One day, when we had a smooth sea and moderate wind, two of my wearied countrymen who were chained together (I was near them at the time), preferring death to such a fife of misery, somehow made through the nettings and jumped into the sea; immediately, another quite dejected fellow, who, on account of his illness, was suffered to be out of irons, also followed their example; and I believe many more would very soon have done the same, if they had not been prevented by the ship's crew, who were instantly alarmed. Those of us that were the most active, were in a moment put down under the deck; and there was such a noise and confusion amongst the people of the ship as I never heard before, to stop her, and get the boat out to go after the slaves.
Equiano's depiction of slave suicide is much like what is depicted in the film. In the film, we see slaves commit suicide that would rather die than see the conditions that faced them in North America. Amistad takes this a step further when it shows slaves being thrown off the ships when rations began to get low on the ship.

At last, when the ship we were in, had got in all her cargo, they made ready with many fearful noises, and we were all put under deck, so that we could not see how they managed the vessel. But this disappointment was the least of my sorrow. The stench of the hold while we were on the coast was so intolerably loathsome, that it was dangerous to remain there for any time, and some of us had been permitted to stay on the deck for the fresh air; but now that the whole ship's cargo were confined together, it became absolutely pestilential. The closeness of the place, and the heat of the climate, added to the number in the ship, which was so crowded that each had scarcely room to turn himself, almost suffocated us. This produced copious perspirations, so that the air soon became unfit for respiration, from a variety of loathsome smells, and brought on a sickness among the slaves, of which many died -- thus falling victims to the improvident avarice, as I may call it, of their purchasers. This wretched situation was again aggravated by the gaffing of the chains, now became insupportable, and the filth of the necessary tubs, into which the clihdren often fell, and were almost suffocated. The shrieks of the women, and the groans of the dying, rendered the whole a scene of horror almost inconceivable.
This description of the slave ships is much like how the film depicts the conditions experienced on the Amistad. What makes Equiano's work compliment the film well is how he fills in the blanks the viewer doesn't see in the film. In this, Equiano describes the smells, the noises, the screams of death. By giving a personal account of these conditions, it makes what the viewer witnesses in Amistad much harder to watch. As John M. said in our weekly discussion, "not only is it important for depictions of the Middle Passage to be spread by films like Amistad, it is crucial that they actually be ACCURATE."

they talked to me in order to cheer me, but all in vain. I asked them if we were not to be eaten by those white men with horrible looks, red faces, and long hair. They told me I was not, and one of the crew brought me a small portion of spirituous liquor in a wine glass; but being afraid of him, I would not take it out of his hand
Equiano writes about the feelings of terror and fear felt at seeing white slavers for the first time, while Amistad illustrates how these feelings turned into anger that led Cinqué to lead a revolt killing the crew of the Amistad.

The first object which saluted my eyes when I arrived on the coast, was the sea, and a slave ship, which was then riding at anchor, and waiting for its cargo. These filled me with astonishment, which was soon converted into terror, when I was carried on board. I was immediately handled, and tossed up to see if I were sound, by some of the crew; and I was now persuaded that I had gotten into a world of bad spirits, and that they were going to kill me
This point really struck me as something that must've been universally felt by all Africans before they traveled to North America. As Equiano described, the feeling of being awestruck at the scale of European ships (which many Africans probably had never seen.) and how that feeling of awestruck turned into terror at what came next.
-
Most of them supposed I had fled towards home; but the distance was so great, and the way so intricate, that they thought I could never reach it, and that I should be lost in the woods. When I heard this I was seized with a violent panic, and abandoned myself to despair. Night, too, began to approach, and aggravated all my fears. I had before entertained hopes of getting home, and had determined when it should be dark to make the attempt; but I was now convinced it was fruitless, and began to consider that, if possibly I could escape all other animals, I could not those of the human kind; and that, not knowing the way, I must perish in the woods. Thus was I like the hunted deer
The unrealistic belief that African slaves could return home is visible in both Equiano's writings, and the movie. However, Equiano realized quite early on that he would never be able to make it home. Conversely, the Amistad slaves hoped that they would be able to steer their ship home. Interestingly, Equiano and Cinqué have two vastly different "endings." Upon his freedom, Equiano stayed in England, where he eventually died seemingly making no attempt to return to Africa, while Cinqué returned back to Africa following his freedom, where he died.

The next day proved a day of greater sorrow than I had yet experienced; for my sister and I were then separated, while we lay clasped in each other's arms. It was in vain that we besought them not to part us; she was tom from me, and immediately carried away, while I was left in a state of distraction not to be described. I cried and grieved continually;
Being ripped from one's family was all too common when Africans were taken as slaves. Like Equiano's work suggests, those that were taken together were even separated from their loved-ones. What's more, Equiano is later briefly reunited with his sisters, albeit for a short time. This was incredibly uncommon as families were usually torn apart permanetly.
-
I remember, in the vessel in which I was brought over, in the men's apartment, there were several brothers, who, in the sale, were sold in different lots; and it was very moving on this occasion, to see and hear their cries at parting. O, ye nominal Christians! might not an African ask you -- Learned you this from your God, who says unto you, Do unto all men as you would men should do unto you? Is it not enough that we are torn from our country and friends, to toil for your luxury and lust of gain? Must every tender feeling be likewise sacrificed to your avarice?
Like Equiano wrote about earlier he writes about how slaves that came together on the ships were still torn from their families and sold. Unlike Equiano, Cinqué was taken from his family that remained in Africa while he was taken to North America.

Trolling Examples
Trolling has its pros whether it be bringing people together, creating communities (ex people who like trolling those indian scammer call centers) and it can surely get a laugh out of people (which I think is the main reason people troll)
-
To go in a different direction for our last example, let’s look at an example of trolling as a form of protest. In the Black Lives Matters protests of 2020, Dallas Police made an app where they asked people to upload videos of protesters doing anything illegal. In support of the protesters, K-pop fans swarmed the app and uploaded as many K-pop videos as they could eventually leading to the app crashing and becoming unusable, and thus protecting the protesters from this attempt at Police surveillance. Read more at the Verge: K-pop stans overwhelm app after Dallas police ask for videos of protesters For another example of trolling as protests, this one with bots, see: A TikToker said he wrote code to flood Kellogg with bogus job applications after the company announced it would permanently replace striking workers
I feel like this example of trolling is more of a form of digital protest as they leveraged the disruption of this troll to actually support a cause. By using trolling in a way to overwhelm platforms with random content, it helps protestors fight against the surveillance and cooperate actions that social media websites take, and this can be a very effective from of activism.

Its interesting how hazing is assumed to be physcially abusing usually but there is also a digital version of it which both cause damage

I find it interesting that there is a distinct difference between Trolling and actual hate speech. Because trolling is intended to invoke a reaction out of users while hate speech is actual hate. I think ethically we need to draw the line on how far we can go while trolling so that people don't get the wrong reaction with sesitive topics.

We can trace Internet trolling to early social media in the 1980s and 1990s, particularly in early online message boards and in early online video games. In the early Internet message boards that were centered around different subjects, experienced users would “troll for newbies” by posting naive questions that all the experienced users were already familiar with. The “newbies” who didn’t realize this was a troll would try to engage and answer, and experienced users would feel superior and more part of the group knowing they didn’t fall for the troll like the “newbies” did. These message boards are where the word “troll” with this meaning comes from.
In this class, I keep finding out new things about things I thought I already knew about. Similar to social media before the internet, I never thought of trolling prior to social media. But it makes sense because trolling doesn't even have to be only on social media; it can be in person or on different forms of the internet. I would think trolling started when the internet came out and people realized they could say things anonymously.

Trolling for newbies highlights the dynamics of online communities, where experienced users assert their status by tricking newcomers. This reinforces group identity through shared knowledge, but it also fosters exclusion and creates barriers for those trying to join, shaping the early culture of internet message boards with elitism.
-
These trolling communities eventually started compiling half-joking sets of “Rules of the Internet” that both outlined their trolling philosophy:
What causes women to be treated unfairly in society? We can always see women being criticized online, from their appearance to their figure to their personality, and in many dirty jokes, women's privacy is the most ridiculed. However, people on the Internet have magnified this misogyny by taking advantage of the "anonymous nature" of the Internet.

I have actually witnessed a lot of trolling online and I realised the trollers want a reaction out of you. Even if its positive or negative they just want a reaction. A good way to stop trollers is to agree with them show a general stance and not show any emotional reaction to there comments
-
Do not argue with trolls - it means that they win
I have heard that it takes two to tango. When one party keeps trying to cause a riot, others will ignore him and he will lose interest in causing a riot. But is this really useful on the Internet? Some people are constantly venting their negative emotions in life through the Internet and spreading negative and pessimistic comments. Our disregard may make them more rampant, so there needs to be specific regulations to reduce the occurrence of such behavior.

Pauses play a key role in turn taking.
How can we use the power of pauses in our conversations to create more meaningful connections with others?
-
Ending a conversation can be just as ritualized as beginning one.
Recognizing the rituals involved in ending conversations is essential for nurturing relationships. Thoughtful closures, whether in person or online, reinforce our connection and ensure that both parties feel valued and respected. These small gestures can significantly enhance the quality of our interactions.
-
Interactions like this one are the building blocks of social rela-tionships
It's remarkable how small, everyday interactions can significantly impact our relationships and well-being. By approaching conversations with openness and affirmation, we not only enhance our connections but also create an environment where individuals feel valued and understood.

Fig. 7.1 On
I know many comments here talk about how much of an outrage making the blue checkmark purchase-able, and in doing so, making trolling way easier than before, however, I would like to add on the ethical POV about verification, identity and authenticity: monetizing one of the only ways to verify an important figure's identity online is definitely a morally wrong decision. When taking a step back and looking at the situation, is a bit more money worth all the problems that arise??

Trolling is when an Internet user posts inauthentically (often false, upsetting, or strange) with the goal of causing disruption or provoking an emotional reaction. When the goal is provoking an emotional reaction, it is often for a negative emotion, such as anger or emotional pain. When the goal is disruption, it might be attempting to derail a conversation (e.g., concern trolling), or make a space no longer useful for its original purpose (e.g., joke product reviews), or try to get people to take absurd fake stories seriously.
Trolling has become very common on social media. And I can't lie; I've been on both sides of the stick during my time on social media. But I realized that I gain absolutely nothing from it, and if someone has to receive happiness from ruining someone else's happiness, then that person isn't in a good spot mentally.

Why troll?
Regarding this issue, I believe the main objectives of trolling are roughly two. Firstly, trolling may be aimed at attracting the attention of internet users and gaining more followers for one's account. Specifically, many account operators will post controversial topics to attract more attention to their works. Some people may follow the operators' accounts to engage in arguments in the controversial topic. When the operators think their accounts have gained enough followers, they may delete the previous controversial topic and change the account's nickname, posting advertisements or other works to earn money. Secondly, trolling may also be aimed at diverting public attention. For example, when a star has negative news, it is very likely that the star's company will troll in order to protect the star's reputation. The company will register many accounts to post controversial topics to gain popularity, while diverting people's attention away from the star.

While most things have two sides, trolling does not seem to have its positive side. There are many users or bots on the internet today who constantly post controversial topics or posts, such as those related to gender opposition; racism, or spreading false information to defame others. Their purpose is simply to bring negative emotions and arguments to internet users. I think that most social media platforms should ban accounts that continuously post controversial topics in order to stop the spread of negative emotions.

I feel like one of the goals of trolling is to manipulate emotions by introducing and using fake content, which then often results in frustration or chaos on this social media pages which can create attention. Trolling does its part in truly undermining genuine conversation between users and it can also turn these social media pages and their comment sections into hostile enviroments.

Some reasons people engage in trolling behavior include:
In some cases, there are may be other reasons that causes people to engage trolling behaviors. People might troll to fit in with a certain online community or group of friends who engage in similar behaviors. Or they may use trolling to get more subscribes and pursue profits.

Punish or stop
One example of Punishment via Trolling that comes to mind is during 2021, Texas opened an abortion reporting site. However, TikTokers from Texas started broadcasting to the fans to overload the website with thousands of fake messages, complete with local zip codes. In this way, people were encouraged to troll in the name of punishing anti-abortion services.

Every “we” implies a not-“we”. A group is constituted in part by who it excludes. Think back to the origin of humans caring about authenticity: if being able to trust each other is so important, then we need to know WHICH people are supposed to be entangled in those bonds of mutual trust with us, and which are not from our own crew. As we have developed larger and larger societies, states, and worldwide communities, the task of knowing whom to trust has become increasingly large. All groups have variations within them, and some variations are seen as normal. But the bigger groups get, the more variety shows up, and starts to feel palpable. In a nation or community where you don’t know every single person, how do you decide who’s in your squad?
As societies grow, trust becomes harder to establish, making group identity more crucial. People often rely on shared values, cultural markers, or common experiences to determine who belongs. The need to define "we" versus "not-we" becomes a way to manage trust and maintain social cohesion in complex, diverse communities.
-
While trolling can be done for many reasons, some trolling communities take on a sort of nihilistic philosophy
I think some of them may not take nihilistic philosophy. A lot of trolling are hired for specific reason, which can be used to infamise their employers' rivals. There are also trolling serve for political ideas. So they may be trolling on purpose.
-
For each theory, think of how many different ways the theory could hook up with the example.
A consequentialist perspective that aligns politcally with the protest could believe that any harm done by the trolling would be outweighted by the impact the protest had, therefor believing it to be ethical. A Kantian perspective believe that acting disingenuously or maliciously, regardless of reason, is always unethical.

then sum-marizing others’ arguments is central to your arsenal of basic moves. Because writers who make strong claims need to map their claims relative to those of other people,
It's important to summarize other views before presenting your own for two reasons: one is to understand other perspectives and be in a position to give your "say," and the other is that it's expected as a way of strengthening your arguments in an academic conversation.

eLife Assessment
This important study uses in vitro and in vivo methods to identify HpARI proteins from H. polygyrus as modulators of the host immune system. The data from comprehensive approaches for investigating differential roles of HpARI proteins are convincing. This paper is relevant to those who investigate host-pathogen interactions at the systems and molecular levels.
-
Reviewer #1 (Public Review):
Colomb et al have further explored the mechanisms of action of a family of three immunodulatory proteins produced by the murine gastrointestinal nematode parasite Heligmosomoides polygyrus bakeri. The family of HpARI proteins binds to the alarmin interleukin 33 and depending on family members, exhibits differential activities, either suppressive or enhancing. The present work extends previous studies by this group showing the binding of DNA by members of this family through a complement control protein (CCP1) domain. Moreover, they identify two members of the family that bind via this domain in a non-specific manner to the extracellular matrix molecule heparan sulphate through a basic charged patch in CCP1. The authors thus propose that binding to DNA or heparan sulphate extends the suppressive action of these two parasite molecules, whereas the third family member does not bind and consequently has a shorter half-life and may function via diffusion.
-
Reviewer #2 (Public Review):
Colomb et al. investigated here the heparin-binding activity of the HpARI family proteins from H. polygyrus. HpARIs bind to IL-33, a pleiotropic cytokine, and modulate its activities. HpARI1/2 has suppressive functions, while HpARI3 can enhance the interaction between IL-33 and its receptor. This study builds upon their previous observation that HpARI2 binds DNA via its CCP1 domain. Here, the authors tested the CCP1 domain of HpARIs in binding heparan sulfate, an important component of the extracellular matrix, and found that 1/2 bind heparan, but 3 cannot, which is related to their half-lives in vivo.

Author response:
The following is the authors’ response to the original reviews.
Reviewer #1 (Public Review):
Summary:
Colomb et al have further explored the mechanisms of action of a family of three immunodulatory proteins produced by the murine gastrointestinal nematode parasite Heligmosomoides polygyrus bakeri. The family of HpARI proteins binds to the alarmin interleukin 33 and depending on family members, exhibits differential activities, either suppressive or enhancing.

The authors thus propose that binding to DNA or heparan sulphate extends the suppressive action of these two parasite molecules, whereas the third family member does not bind and consequently has a shorter half-life and may function via diffusion.
Strengths:
A strength of the work is the multifaceted approach to examining and testing their hypotheses, using a well-established and well-defined family of immunomodulatory molecules using multiple approaches including an in vivo setting.
Weaknesses:
There are a few weaknesses of the approach. Perhaps some discussion and speculation as to how these three family members might operate in concert during Heligmosomoides polygyrus bakeri infection would help place the biology of these molecules in context for the reader, e.g. when and where they are produced.
We agree that the roles of these proteins during infection requires further study and is not fully elucidated in infection here. We have added further discussion to the manuscript on their potential roles during infection (track changes manuscript, lines 277 – 283).

Here, the authors tested the CCP1 domain of HpARIs in binding heparan sulfate, an important component of the extracellular matrix, and found that 1/2 bind heparan, but 3 cannot, which is related to their half-lives in vivo.
Strengths:
The authors use a comprehensive multidisciplinary approach to assess the binding and their effects in vivo, coupled with molecular modeling.
Weaknesses:
(1) Figure 1C should include Western.
We apologise for this oversight, and now include an uncropped western blot image as a Figure 1, Figure Supplement 1.
(2) Figure 1E: Why does HpARI1 stop binding DNA at 50%?
It is currently unclear why HpARI1 does not bind to all DNA in the EMSA assay, however this was our repeated finding. With our revised findings we can now state definitively that HpARI1 has a lower affinity for HS compared to HpARI2, and in each of our assays (EMSA (Fig 1D-E), size exclusion chromatography (Fig 4A), HS-bead pull-down (Fig 4B), lung cell surface binding (Fig 4C) and ITC (Fig 4D)) HpARI1 always shows a weaker response compared to HpARI2. We hypothesise that HpARI1 binds more weakly to DNA/HS to allow it to diffuse further from the site of deposition, but we have yet to demonstrate this during infection. We add further discussion of this point (track changes manuscript, lines 262 – 266).
(3) ITC binding experiment with HpARI1? Also, the ITC results from HpARI2 do not seem to saturate, thus it is difficult to really determine the affinity.
We have now included HpARI1-HS ITC, and re-ran the HpARI2 experiment to saturation (Fig 4D-E).
(4) It would be helpful to add docking results from HpARI1.
We have now included HpARI1-HS docking, in Figure 5B.
(5) Some conclusions are speculative and need to remain in the Discussion. e.g.: a) That HpARI3 may be able to diffuse farther
We have rewritten these points to remove the speculation on localisation from the abstract (lines 18-19) and introduction (line 78).
b) That DNA/HS may trap HpARI1/2 at the infection site.
Likewise, these points have been rewritten in the abstract and introduction as above, and we have made it clearer that this is a model that we are proposing in the discussion (line 277-283).
Reviewer #1 (Recommendations For The Authors):
The paper is well-written and the data well-presented. I have one small comment that the authors may like to consider. In the discussion, second paragraph, line 17, perhaps, "evolved" rather than "developed".
Thank you for this suggestion, we have made this change (line 248).

Debate continues over the effectiveness of transplantation in conserving threatened coral species, increasing coral abundance, and accelerating reef restoration
Some argue that while transplantation can help, it may not address the root causes of coral decline, such as water quality degradation or rising ocean temperatures. Without mitigating these broader issues, coral transplants may simply fail over time. However, others see transplantation as a crucial stopgap measure to preserve key species and habitats while long-term solutions are developed
-
there is a deepening awareness that no habitat, once damaged or degraded, can be restored to its original condition
The reality is that restoration efforts, while beneficial, may never fully return coral reefs to their pristine state. This is due to the complex interactions between species, environmental conditions, and historical degradation. As a result, conservationists now focus on creating resilient reefs that can survive in future conditions rather than merely replicating past ecosystems
-
Continuing declines and the lack of recovery on coral reefs worldwide have sparked renewed calls for action by the scientific, conservation, and reef management communities
Coral reefs are known as the "rainforests of sea", these are the biodiversity hotspots that support a vast range of marine species. However, their rapid decline due to climate change, overfishing, and pollution has created an urgent need for restoration strategies. Scientists and conservationists now face the challenge of reversing damage to these ecosystems, which are vital for both marine life and coastal human populations.

Data can be poisoned intentionally as well. For example, in 2021, workers at Kellogg’s were upset at their working conditions, so they agreed to go on strike, and not work until Kellogg’s agreed to improve their work conditions. Kellogg’s announced that they would hire new workers to replace the striking workers: Kellogg’s proposed pay and benefits cuts while forcing workers to work severe overtime as long as 16-hour-days for seven days a week. Some workers stayed on the job for months without a single day off. The company refuses to meet the union’s proposals for better pay, hours, and benefits, so they went on strike. Earlier this week, the company announced it would permanently replace 1,400 striking workers. People Are Spamming Kellogg’s Job Applications in Solidarity with Striking Workers – Vice MotherBoard People in the antiwork subreddit found the website where Kellogg’s posted their job listing to replace the workers. So those Redditors suggested they spam the site with fake applications, poisoning the job application data, so Kellogg’s wouldn’t be able to figure out which applications were legitimate or not (we could consider this a form of trolling). Then Kellogg’s wouldn’t be able to replace the striking workers, and they would have to agree to better working conditions. Then Sean Black, a programmer on TikTok saw this and decided to contribute by creating a bot that would automatically log in and fill out applications with random user info, increasing the rate at which he (and others who used his code) could spam the Kellogg’s job applications:
The Kellogg's incident, in which the general public used electronic means to interfere with the company's operations, is a fascinating illustration of collective resistance in the digital age. It, in my opinion, represents society's reaction to large businesses abusing their power. But this kind of "data poisoning" begs the moral dilemma of how to define an appropriate mode of dissent. Although flooding the hiring process with phony applications paralyzes it, it may have unintended consequences for other parties, therefore a deeper analysis of the boundaries of technical confrontation is required.

Social media platforms collect various types of data on their users. Some data is directly provided to the platform by the users. Platforms may ask users for information like: email address name profile picture interests friends Platforms also collect information on how users interact with the site. They might collect information like (they don’t necessarily collect all this, but they might): when users are logged on and logged off who users interact with What users click on what posts users pause over where users are located what users send in direct messages to each other Online advertisers can see what pages their ads are being requested on, and track users across those sites. So, if an advertiser sees their ad is being displayed on an Amazon page for shoes, then the advertiser can start showing shoe ads to that same user when they go to another website.
Social media collects user data not only to improve the user experience, but also for compelling business purposes. This makes me wonder: if data collection becomes more widespread, do we have appropriate control over what data is used? While users often implicitly agree to data collecting tactics when they sign up, this does not mean they fully understand how the data will be used. As a result, this behavior is not always desired and may occasionally go against the user's wishes.

eLife Assessment
This is an important study on the damage-induced checkpoint maintenance and termination in budding yeast that provides novel and convincing evidence for a role of the spindle assembly checkpoint and mitotic exit network in halting the cell cycle after prolonged arrest in response to irreparable DNA double strand breaks (DSBs). The study identifies particular components from these checkpoints that are specifically required for the establishment and/or the maintenance of a cell cycle block triggered by such DSBs. The authors propose an interesting model for how these different checkpoints intersect and crosstalk for timely resumption of cell cycling even without repairing DNA damage that has been revised by addressing the bulk of the reviewers' comments to the first version of the manuscript.
-
Reviewer #1 (Public review):
Summary:
In their manuscript, Zhou et al. analyze the factors controlling the activation and maintenance of a sustained cell cycle block in response to persistent DNA DSBs. By conditionally depleting components of the DDC using auxin-inducible degrons, the authors verified that some of them are only required for the activation (e.g., Dun1) or the maintenance (e.g., Chk1) of the DSB-dependent cell cycle arrest, while others such as Ddc2, Rad24, Rad9 or Rad53 are required for both processes. Notably, they further show that after a prolonged arrest (>24 h) in a strain carrying two DSBs, the DDC becomes dispensable and the mitotic block is then maintained by SAC proteins such as Mad1, Mad2 or the mitotic exit network (MEN) component Bub2.
Strengths:
The manuscript dissects the specific role of different components of the DDC and the SAC during the induction of a cell cycle arrest induced by DNA damage, as well as their contribution for the short-term and long-term maintenance of a DNA DSB-induced mitotic block. Overall, the experiments are well described and properly executed, and the data in the manuscript are clearly presented. The conclusions drawn are generally well supported by the experimental data. Their observations contribute to drawing a clearer picture of the relative contribution of these factors to the maintenance of genome stability in cells exposed to permanent DNA damage.
Weaknesses:
The main weakness of the study is that it is fundamentally based on the use of the auxin-inducible degron (AID) strategy to deplete proteins. This widely used method allows an efficient depletion of proteins in the cell. However, the drawback is that a tag is added to the protein, which can affect the functionality of the targeted protein or modify its capacity to interact with others. In fact, three of the proteins that are depleted using the AID systems are shown to be clearly hypomorphic, and hence their capacity to induce a strong checkpoint response might be compromised. A corroboration of at least some of the results using an alternative manner to eliminate the proteins would help to strengthen the conclusions of the manuscript.

Reviewer #2 (Public review):
Summary:
The manuscript analyzes and attempts to discriminate genetic requirements for DNA damage-induced cell cycle checkpoint induction, maintenance, and adaptation in budding yeast bearing one or two unrepairable DNA double strand breaks using auxin-induced degradation (AID) of key DNA damage response (DDR) factors. The study paid particular attention to solving a puzzle regarding how yeasts bearing two unrepaired DNA breaks fail to engage in "adaptation" whereas those with a single unrepairable break eventually resume cell cycling after a prolonged (up to 12 h) G2 arrest.
The key findings are: 1. Genetic requirements for the entry and the maintenance of DDC are separable. For instance, Dun1 is partially required for the entry but not the DDC maintenance whereas Chk1 is only required for maintenance. 2. Cells with two unrepairable breaks respond to DDR only up to a certain time (~12-15 h post damage) and beyond this point, depend on spindle assembly checkpoint (SAC) and mitotic exit network (MEN) to halt cell cycling. 3. The authors also propose an interesting concept that the location of DNA breaks and their distance to centromeres are important factors dictating the effect of SAC/MEN on the duration of cell cycle arrest after prolonged arrest (and cells become "deaf" to persistent arrest signals) and yeast's adaptability following DNA damage. The results provide most compelling evidence to date on the role of SAC/MEN in DNA damage response and cell cycle arrest albeit its impact might be limited to the handful of model systems due to the vastly different centromeric elements and far larger chromosome sizes in metazoan cells. The study albeit briefly discussed the basis of transitions from entry, maintenance, and adaptation ( ex. changes in centromeric architectures), it does not offer detailed explanations or a testable hypothesis to this topic.
Overall, the conclusion of the study is well supported by the elegant set of genetic experimental data and employed multiple readouts on DDC factor depletion on checkpoint integrity and cell cycle status. Although the study simply measures Rad53 phosphorylation as the primary metric to assess checkpoint status, it successfully demonstrated how the signaling is modified through the different stages and that eventually cells become recalcitrant to DDC signaling after a prolonged arrest. The results are clear, and rigorously tested and carefully interpreted with good discussion on the possible limitations. The revision provided detailed responses to the reviewers' comments and addressed a few key concerns, one of which is universally raised by the reviewers on the full functionality of AID tagged DDC factors, by simply expressing excess Rad9-AID to restore more normal looking checkpoint response. It will be interesting if the excess expression of other DDC factors could overcome suboptimal checkpoints in cells after 24 h post damage.

Reviewer #3 (Public review):
Summary:
The DNA damage checkpoint (DDC) inhibits the metaphase-anaphase transition to repair various types of DNA damage, including DNA double strand breaks (DSBs). One irreparable DSB can maintain the DDC for 12-15 hours in yeast, after which the cells resume the cell cycle. If there are two DSBs, the DDC is maintained for at least 24 hours. In this study, the authors take advantage of this tighter DDC to investigate whether the best-known proteins involved in establishing the DDC are also responsible for its long-term maintenance during irreparable DSBs. They do this by cleverly degrading such proteins after DSB formation. They show that most, but not all, DDC proteins maintain the cell cycle block. Interestingly, DDC proteins become dispensable after 15 hours and the block is then maintained by spindle assembly checkpoint (SAC) proteins.
Strengths:
The authors have engineered a tight yeast system to study DDC shutdown after irreparable DSBs and used it to address whether checkpoint proteins (DDC and SAC) contribute to the long-term maintenance of DSB-mediated G2/M block. The different roles of Ddc2, Chk1 and Dun1 are interesting, while the fact that SAC overtakes DDC after 15 hours is intriguing and highlights how DSBs near and far from centromeres can have a profound impact on cell adaptation to DSBs. In their revision, the authors have now improved the Rad9-AID methodology to place Rad9 in the context of DDC adaptation, as well as widening the association between adaptation and proximity to centromeres.
Weaknesses:
Some of the results they present essentially confirm their own previous findings, albeit with a tighter strain design for long-term arrest. Conclusions about the maintenance of G2/M in several mutant combinations could have been strengthened by adding simple microscopy experiments with DAPI staining. No clear mechanism for how depletion of Bub2, but not Bfa1, can relieve the G2/M (metaphase) block is given.
-
Author response:
The following is the authors’ response to the original reviews.
Reviewer #1 (Recommendations For The Authors):
To hopefully contribute to more strongly support the conclusions drawn by the authors, I am including a series of concerns regarding the manuscript, as well as some suggestions that could be useful to address these issues:
(1) The main results of this study derive from the use of auxin-inducible degron (AID)-tagged proteins. Despite the great advantages of the AID strategy to conditionally deplete proteins, the AID tag can affect the normal function of a protein. In fact, some of the AID-labeled DDC components generated in this work are shown to be hypomorphic. Hence, the manuscript would have benefited from the additional confirmation of some of the observations using a different way to eliminate the proteins (e.g., temperature-sensitive mutants).
Most ts mutants are also hypomorphic; hence we don’t see there is much advantage to their use. The addition of the AID to these proteins alone does not interfere with the ability to sustain checkpoint arrest as demonstrated in Figure S1. Instead we found that by overexpressing Rad9-AID we could demonstrate that inactivating Rad9 after 15 h behaved the same way as the inactivation of Ddc2, significantly strengthening our finding that the DDC checkpoint becomes dispensable while the SAC takes over.
(2) In cells depleted of Rad53-AID, the deletion of CHK1 stimulates an earlier release from a mitotic arrest induced by two DSBs (Figures 2D and 3C). Likewise, the authors claim that a faster escape from the cell cycle block can also be observed when upstream factors such as Ddc2, Rad9, or Rad24 are depleted in the absence of CHK1 (Figures 2A-C and Figures 3D-F). However, this earlier release from the cell cycle arrest, if at all, is only slightly noticeable in a Rad9-AID background (Figures 2B and 3E). In this sense, it is also worth pointing out that Rad9-AID chk1Δ (Figure 3E) and Rad24-AID chk1Δ (Figure 3F) cells were only evaluated up to 7 h, while in all other instances, cells were followed for 9 h, which hinders a fair assessment of the differences in the release from the cell cycle arrest.
As noted above, we have now been able to examine Rad9 over the long-time frame.
(3) Although only 25% of the cells depleted for Dun1 remained in G2/M arrest 7 h following the induction of two DSBs, it is shocking that Rad53 was nonetheless still phosphorylated after the cells had escaped the cell cycle blockage (Figure 4A).
This persistence of Rad53 phosphorylation is also seen with the inactivation of Mad2, allowing escape in spite of continued Rad53 phosphorylation.
(4) Generation of Rad9-AID2 and Rad24-AID2 strains did not fully restore the function of these proteins, since most cells had adapted 24 h after induction of two DSBs (Figure S1C). Nonetheless, Rad9-AID2 and Rad24-AID2 are still likely more stable than their AID counterparts, and hence the authors could have instead used the AID2 proteins for the experiments in Figure 2 to better evaluate the role of Rad9 and Rad24 in the maintenance of the DDC-dependent arrest.
We note again that we have found a way to study Rad9 up to 24 h.
(5) Deletion of BFA1 has been shown to promote the escape from a cell cycle arrest triggered by telomere uncapping (Wang et al. 2000, Hu et al. 2001, Valerio-Santiago et al. 2013). Likewise, while cells carrying the cdc5-T238A allele cannot adapt to a checkpoint arrest induced by one irreparable DSB, BFA1 deletion rescues the adaptation defect of this mutant CDC5 allele (Rawal et al., 2016). The authors show how, using AID-degrons of Bfa1 and Bub2, that only Bub2, but not Bfa1, is required to maintain a prolonged cell cycle arrest after the induction of two DSBs. To reinforce this point, and as shown for mad2Δ cells (Figure S6A), the authors could perform a complete time course using both the Bfa1-AID and a bfa1Δ mutant to demonstrate that they do indeed show the same behavior in terms of the adaptation to a two DSB-induced cell cycle arrest.
We thank the reviewer for noting these other instances where bfa1D promoted an escape from arrest. We tested a 2-DSB bfa1 deletion, data has been added to Figure S9E-F. We did not observe a difference in the percentage of cells escaping arrest between the 2-DSB bfa1 deletion and the 2-DSB BFA1-AID strains.
(6) Bypass or adaptation of a checkpoint-induced cell cycle arrest in S. cerevisiae often leads to cells entering a new cell cycle without doing cytokinesis and, hence, to the accumulation of rebudded cells. However, the experiments shown in the manuscript only account for G1 or budded cells with either one or two nuclei. Do any of the mutants show cytokinesis problems and subsequent rebudding of the cells? If so, this should have been also noted and quantified in the corresponding assays.
In the cases we have studied we have not seen instances where the cells re-bud without completing mitosis (at least as assessed by the formation of budded cells with two distinct DAPI staining masses). In the morphological assays we have done, we score the continuation of the cell cycle by the appearance of multiple buds, G1, and small budded cells. In our adaptation assays when cells escaped G2/M arrest they formed microcolonies indicating no short-term deficiency in cell division.
(7) The location of the DSB relative to the centromere of a chromosome seems to be a factor that determines the capacity of the SAC to sustain a prolonged cell cycle arrest. The authors discuss the possibility that the DSB could somehow affect the structure of the kinetochore. Did they evaluate whether Mad1 or Mad2 were more actively recruited to kinetochores in those strains that more strongly trigger the SAC after induction of the DSBs?
We have not attempted to follow Mad1/2 recruitment. ChIP-seq could be used to monitor Mad1/2 localization at the 16 centromeres in response to DSBs and the spread of g-H2AX across the centromere. Our previous data showed that g-H2AX could spread across the centromere region and could create a change that would be detected by Mad1/2. This change does not, however, affect the mitotic behavior of a strain in which the H2A genes have been modified to the possibly phosphomimetic H2A-S129E allele.
(8) The authors could speculate in the discussion about the reasons that could explain why the DDC is required for the maintenance of checkpoint arrest at early stages but then becomes dispensable for the preservation of a prolonged cell DNA DSB-induced cycle arrest, which is instead sustained at later stages by the SAC.
Our suggestion is that cells would have adapted, but modification of the centromere region engages SAC.
Finally, some minor issues are:
(1) The lines in the graphs that display the results from adaptation assays (e.g., Figures 1B and 1E) or cell and nuclear morphology (e.g., Figures 1D and 1G) are too thick. This makes it sometimes difficult to distinguish the actual percentages of cells in each category, particularly in the experiments monitoring nuclear division.
Fixed
(2) While both the adaptation assay and the analysis of nuclear division in Figures 1E and 1G, respectively, show a complete DDC-dependent arrest at 4h, the Western blot in Figure 1F suggests that Rad53 is not phosphorylated at that time point. Do these figures represent independent experiments? Ideally, the analysis of cell budding and nuclear division, which is performed in liquid cultures, and the Western blot displaying Rad53 phosphorylation should correspond to the same experiment.
Cell budding in liquid cultures and adaptation assays were performed in triplicate with 3 biological replicates and the collective results are shown in each graph showing the percentage of large-budded cells. Western blot samples were collected in each liquid culture experiment. The western blot in 1G is a representative western blot.
(3) It is somewhat confusing that the blots for the proteins are not displayed in the same order in Figures 2A (Rad53 at the top) and 2B or 2C (Rad53 in the middle).
Fixed. We place Rad53 – the relevant protein - at the top.
Reviewer #2 (Recommendations For The Authors):
(1) Yeast with the two breaks responds to DNA damage checkpoint (DDC) until sometimes 4-15 h post DNA damage. Since the auxin-induced degradation does not completely deplete all the tagged proteins in cells, the results should be more carefully considered and not to interpret if the checkpoint entry or maintenance depends on each target protein's ability to induce Rad53 phosphorylation. It should be theoretically possible if checkpoint maintenance requires only a modest amount of checkpoint factors especially because the experiments involve the induction of one or two DSBs. The low levels of DDC factors may be insufficient for Rad53 activation but could still be effective for cell cycle arrest. Indeed, the Haber group showed that the mating type switch did not induce Rad53 phosphorylation but still invoked detectable DNA damage response. To test such possibilities, the authors might consider employing yet another marker for DDC such as H2A or Chk1 phosphorylation besides Rad53 autophosphorylation. Alternatively, the authors might check if auxin-induced depletion also disrupts break-induced foci formation for checkpoint maintenance or their enrichment at DNA breaks using ChIP assays at various points post-damage.
DAPI staining of Ddc2-AID cells show that when IAA is added 4 h after DSB induction (Figure S3A), cells escape G2/M arrest as evidenced by the increase in large-budded cells with 2 DAPI signals, small budded cells, and G1 cells. Overexpression of Ddc2 can sustain the checkpoint past 24 h, but without SAC proteins like Mad2 they will eventually adapt (Figure S6B).
That Rad9-AID or Rad24-AID in the absence of added auxin (but in the presence of TIR1) is unable to sustain arrest suggests to us that low levels of Rad9 or Rad24 are not sufficient to maintain arrest. As the reviewer notes, normal MAT switching doesn’t cause Rad53 phosphorylation or arrest, though early damage-induced events such as H2A phosphorylation do occur. But our point is that Rad9 or Ddc2 is needed to maintain arrest only up to a certain point, after which they become superfluous and a different checkpoint arrest is imposed. At that point apparently a low level of these proteins plays no obvious role.
(2) It is interesting that DDC no longer responds to the damage signaling after 15 h of DSB-induced prolonged checkpoint arrest after two DNA double-strand breaks. Is this also applicable to other adaptation mutants? The results might improve the broad impact of the current conclusions. It is also possible that the transition from DDC to SPC depends on simply the changes in signaling or in part due to the molecular changes in the status of DNA breaks or its flanking regions. Indeed, the proposed model suggests that the spreading of H2A phosphorylation to centromeric regions induces SAC and thus mitotic arrest. The authors could measure H2A phosphorylation near the centromere using ChIP assays at various intervals post-DNA damage. It is particularly interesting if depletion of Ddc2 at 15 h post DNA damage does not alter the level of H2A phosphorylation at or near centromere.
Our previous data have suggested that the involvement of the SAC in prolonging DSB-induced arrest involved post-translational modification of centromeric chromatin such as the Mec1- and Tel1-dependent phosphorylation of the histone H2A (Dotiwala). In budding yeast there is also a similar DSB-induced modification of histone H2B (Lee et al.). To ask if there is an intrinsic activation of the SAC if the regions around centromeres were modified by checkpoint kinase phosphorylation, we examined cell cycle progression in strains in which histone H2A or histone H2B was mutated to their putative phosphomimetic forms (H2A-S129E and H2B-T129E). As shown in Figure S11, there was no effect on the growth rate of these strains, or of the double mutant, suggesting that cells did not experience a delay in entering mitosis because of these modifications. We note that although histone H2A-S129E is recognized by an antibody specific for the phosphorylation of histone H2A-S129, the mutation to S129E may not be fully phosphomimetic.
(3) It is puzzling why Rad9-AID or Rad24-AID are proficient for DDC establishment but cannot sustain permanent arrest in the two break cells. It appears Rad53 phosphorylation for DDC is weaker in cells expressing Rad9-AID or Rad24-AID according to Fig.2B and C even though their protein level before IAA treatment is still robust. This might also explain why the results of depleting Rad53 and Rad9 are very different. It also raises concern if the effect of Rad24 depletion on checkpoint maintenance is in part due to the weaker checkpoint establishment. It might be necessary to use the AID2 system to redo Rad24 depletion to exclude such a possibility.
We believe that the AID mutants are very sensitive to the low level of IAA present in yeast. The instability of the protein is entirely dependent on the TIR1 SCF factor, so the proteins themselves are not intrinsically defective; they are just subject to degradation. Overexpressing Rad9 allowed us to evaluate its role at late time points.
(4) It is intriguing that the switch from DDC to SAC might take place at around 12 h when yeasts with a single unrepairable break ignore DDC and resume cell cycling (so-called "adaptation"). Since 4h and 15h are far apart and the transition point from DDC to SAC likely takes place between these two points, it will be very helpful to analyze and compare cell cycle exit after 24 h by treating IAA at multiple points between 4-15h.
When we add IAA to Mad2-AID and Mad1-AID 4 h after DSB induction, cells remain arrested for up to 12 h after DSB induction. At 15 h cells begin to exit checkpoint arrest indicating that the handoff of checkpoint arrest must occur between 12 to 15 h after DSB induction. If we degraded DNA damage checkpoint proteins at any point before Mad2, Mad1, and Bub2 begin to contribute to checkpoint arrest, then arrested cells will likely adapt in a similar manner to when IAA was added 4 h after DSB induction.
(5) Some of the Western blot quality is poor. For instance, in Figure 6C, Mad1-AID level after IAA addition is not compelling especially because the TIR level (the loading control) is also very low.
In Figure 6C, while the relative levels of TIR1 are similar in the IAA treated and untreated samples, there is no detectable amount of Mad1-AID in the IAA treated samples indicating that Mad1-AID was successful degraded with the AID system.
(6) Fig. 8 is complex. It might be helpful to define the different types of arrows in the figure. The legend also has a spelling error, Rad23 should be Rad24.
We’ve defined what each arrow means in the legend and corrected the spelling error in the figure legend.
Reviewer #3 (Recommendations For The Authors):
Major concerns:
Much of the manuscript states that two unrepairable DSBs lead to a long and severe G2/M arrest. Two main cytological approaches are used to make this statement: bud size and number on plates after micromanipulation (microcolony assay), and cell and nuclear morphology in liquid cultures. While the latter gives a clear pattern that can be assigned to a G2/M block as expected by DDC, i.e. metaphase-like mononucleated cells with large buds, the former can only tell whether cells eventually reach a second S phase (large budded cells on the plate can be in a proper G2/M arrest, but can also be in an anaphase block or even in the ensuing G1). The authors always performed the microcolony assay, but there are several cases where the much more informative budding/DAPI assay is missing. These include Dun1-aid and others, but more importantly chk1D and its combinations with DDC proteins. Incidentally, for the microcolony assay, it is more accurate to label the y-axis of the corresponding graphs (and in the figure legends and main text) with something like "large budded cells"; "G2/M arrested cells" is misleading.
Figures have been updated to more accurately reflect what we are measuring.
The results obtained with the Bfa1/Bub2 partner are intriguing. These two proteins form a complex whose canonical function is to prevent exit from mitosis until the spindle is properly aligned, acting in a distinct subpathway within the SAC that blocks MEN rather than anaphase onset. The data presented by the authors suggest that, on the one hand, both SAC subpathways work together to block the cell cycle. However, why does canonical SAC (Mad1/Mad2) inactivation not lead to a transition from G2/M (metaphase-like) arrested cells to anaphase-like arrest maintained by Bfa1-Bub2? Since Bfa1-Bub2 is a target of DDC, is it possible that DDC knockdown also inactivates this checkpoint, allowing adaptation? On the other hand, can the authors provide more data to confirm and strengthen their claim of a Bfa1-independent Bub2 role in prolonged arrest? Perhaps long-term protein localization and PTM changes. Bub2-independent roles for Bfa1 have been reported, but not vice versa, to the best of my knowledge.
In the mitotic exit network Bfa1/Bub2 prime activation of the pathway by bringing Tem1 to spindle pole bodies. Phosphorylation of Bfa1 causes Tem1 to be released and phosphorylate Cdc5 to trigger exit by MEN. It has been shown that DNA damage, in a cdc13-1 ts mutant, phosphorylates Bfa1 in a Rad53 and Dun1 dependent manner. This phosphorylation of Bfa1 could release Tem1 and prime cells to exit checkpoint arrest when cells pass through anaphase. Looking at Tem1 localization to spindle pole bodies and interactions with Bfa1/Bub2 in response to DNA damage might give insight into why cells don’t experience an anaphase-like arrest when they are released by either deactivation of the DNA damage checkpoint or SAC.
We have previously shown that a deletion of bub2 in a 1-DSB background shortens DSB-induced checkpoint arrest. Deletion of bfa1 in a 2-DSB background showed ~80-70% of cells stuck in a large-budded state as measured through an adaptation assay tracking the morphology of G1 cells on a YP-Gal plate and DAPI staining. Deletion or degradation of bfa1 might not release cells from arrest because the Mad2/Mad1 prevent cells from transitioning into anaphase. Our DAPI data for Bub2-AID shows an increase in cells with 2 DAPI signals (transition into anaphase) and small budded cells indicating that degradation of Bub2 is releasing cells into anaphase and allowing cells to complete mitosis.
Further suggestions:
It would be richer if authors could provide more than one experimental replicate in some panels (e.g., S1A,B; S4A; and S6B).
S1C confirms that Rad9-AID and Rad24-AID will adapt by 24 h even with the point mutant TIR1(F74G) which has lower basal degradation than TIR1. S4A has been updated with additional experimental replicates. The 48 h timepoint after DSB induction was to show the importance of Mad2 even when Ddc2 is overexpressed.
Figure 1: Rearrange figure panels when they are first mentioned in the text. For example, it makes more sense to have the plate adaptation assay as panel B for both 1-DSB and 2-DSB strains, budding plus DAPI as panel C, and Rad53 as panel D.
These figures have been rearranged in the order that they are mentioned in the paper.
Figure 5: Correct Ph-5-IAA in the Rad53 WBs (it should be 5-Ph-IAA).
This has been corrected.
Figure S2: The straight line under the "+IAA" text box is misleading. I think it should also cover the "-2" time point, right? Also, check the figure legend. Information is missing and does not correspond to the figure layout.
This has been corrected.
Figure S3: Perhaps "Cell cycle profile as determined by budding and DAPI staining" is a better and more accurate legend title.
The legend title has been updated to “Cell cycle profile as determined by budding and DAPI staining in Ddc2-AID and Rad53-AID mutants ± IAA 4 h after galactose.”
Figure S5: Detection of both Rad53 and Ddc2 in the same blot could lead to misinterpretation as hyperphosphorylated Rad53 appears to coincide with Ddc2 migration.
Figure S5A-B are representative western blots where Rad53 was probed to show activation of the DNA damage checkpoint by Rad53 phosphorylation. When measuring the relative abundance of Ddc2 we did not probe all blots for Rad53.
Table S1: Include the post-hoc test used for comparisons after ANOVA.
A Sidak post-hoc test was used in PRISM for the one-way ANOVA test. PRISM listed the Sidak post-hoc test as the recommended test to correct for multiple comparisons. A column has been added to S. Table 1 to show which post-hoc test was used.
Page 10, line 4: The putative additive effect of chk1 knockout with Dun1 depletion should also be compared to chk1 alone (in Figure 3A).
We address the additive effect of chk1 knockout with Dun1-AID depletion in a later section on Page 11, line 6. Since we had not explored possible effects from downstream targets of Rad53 for prolonging checkpoint arrest when Rad53 was depleted, we did not mention the effect of the chk1 knockout on Dun1 depletion.
Page 14, second paragraph, line 4: "Figure 6A-D", is it not?
Figure S6A is measuring checkpoint arrest in a deletion of mad2 in a 2-DSB strain. Figure 6A-D shows how degradation of Mad2-AID and Mad1-AID after the handoff of arrest causes cells to exit the checkpoint in a Rad53 independent manner.

Pet owners had lower PTSD scores 4.4 years after the disaster than non-pet owners (p = 0.0035)
The long term emotional benefits ofpet oeneership became evident in the lower PTSD scores among pet owners over time. This suggests that pets may serve as a critical source of emotional support during the long-term recovery phase. Pets provide companionship, a sense of routine, and an emotional outlet, all of which contribute to reducing feelings of isolation and anxiety. The act of caring for a pet may also help restore a sense of purpose and normalcy in a post-disaster context. Moreover, interacting with pets has been shown to increase levels of oxytocin, a hormone associated with reducing stress and promoting feelings of well-being. In the context of prolonged recovery, where survivors may struggle with ongoing challenges like housing instability, financial difficulties, and rebuilding their lives, pets can offer consistency and unconditional love, which may buffer against the development of long-term psychological disorders like PTSD. This effect highlights the potential role of animal-assisted therapy or pet ownership as part of mental health interventions in disaster recovery programs.
-
Pet ownership did not have an association with PTSD score 1 month after the disaster (p = 0.337)
The psychological. trauma and shock are so overwhelming that specific factors like pet ownership may not show a measurable impact on mental health outcomes. One potential explanation for the lack of a significant association between pet ownership and PTSD scores one month after the disaster is that all evacuees, regardless of whether they owned pets, were dealing with a similar level of acute stress and disruption. The chaos of the evacuation, uncertainty about future, and loss of property or loved ones likely overshadowed the nuanced emotional benefits that pets might offer. Furthermore, the conditions in evacuation shelters could have been so challenging for both humans and animals that any potential comfort a pet could provide was mitigated by the logistical difficulties of caring for them in such an environment. The delay in showing a positive effect on mental health suggests that pets may play a more substantial role in long-term recovery rather than in the immediate aftermath of a disaster.
-
Acceptance of animals at human evacuation shelters depended on the discretion of shelter's chief operating officer
The fact that pet acceptance was left to the discretion of individual shelter managers reveals the absence of a national or regional policy for handling animals in emergency situations. This lack of standardized protocol created a highly inconsistent experience for evacuees. In some shelters, animals were allowed but kept in separate areas, while in others, pets were outright refused. This inconsistency led to frustration, as many pet owners felt forced to make difficult choices between their own safety and their responsibility to their pets. The emotional toll on evacuees was exacerbated by the uncertainty of not knowing if their shelter would accept pets, causing additional anxiety during an already traumatic situation. This scenario highlights the need for comprehensive disaster planning that explicitly addresses pet welfare, ensuring uniformity and reducing the stress on pet owners during evacuations.

eLife Assessment
This important study examines the role of Microrchidia (MORC) proteins in the human malaria parasite Plasmodium falciparum. Solid experimental results, including genome editing and chromatin profiling methods (ChIP-seq and Hi-C), provide a comprehensive picture of the critical role MORC plays in shaping parasite chromatin. Depletion of MORC results in a lethal collapse of heterochromatin and parasite death, nominating the factor as a new target of antimalarial therapies.
-
Reviewer #1 (Public review):
Summary:
The authors investigated the function of Microrchidia (MORC) proteins in the human malaria parasite Plasmodium falciparum. Recognizing MORC's implication in DNA compaction and gene silencing across diverse species, the study aimed to explore the influence of PfMORC on transcriptional regulation, life cycle progression and survival of the malaria parasite. Depletion of PfMORC leads to the collapse of heterochromatin and thus to the killing of the parasite. The potential regulatory role of PfMORC in the survival of the parasite suggests that it may be central to the development of new antimalarial strategies.
Strengths:
The application of the cutting-edge CRISPR/Cas9 genome editing tool, combined with other molecular and genomic approaches, provides a robust methodology. Comprehensive ChIP-seq experiments indicate PfMORC's interaction with sub-telomeric areas and genes tied to antigenic variation, suggesting its pivotal role in stage transition. The incorporation of Hi-C studies is noteworthy, enabling the visualization of changes in chromatin conformation in response to PfMORC knockdown.
Weaknesses:
Although disruption of PfMORC affects chromatin architecture and stage-specific gene expression, determining a direct cause-effect relationship requires further investigation. Furthermore, while numerous interacting partners have been identified, their validation is critical and understanding their role in directing MORC to its targets or in influencing the chromatin compaction activities of MORC is essential for further clarification. In addition, the authors should adjust their conclusions in the manuscript to more accurately represent the multifaceted functions of MORC in the parasite.

We greatly appreciate the overall positive feedback and cognisense of our efforts. Our application of CRISPR/Cas9 genome editing tools coupled with complementary cellular and functional approaches shed light on the importance of _Pf_MORC in maintaining chromatin structural integrity in the parasite and highlights this protein as a promising target for novel therapeutic intervention.
Weaknesses: Although disruption of PfMORC affects chromatin architecture and stage-specific gene expression, determining a direct cause-effect relationship requires further investigation.
Our conclusions were made on the basis of multiple, unbiased molecular and functional genomic assays that point to the relevance of the _Pf_MORC protein in maintaining the parasite’s chromatin landscape. Although we do not claim to have precise evidence on the step-by-step pathway to which _Pf_MORC is involved, we bring forth first-hand evidence of its role in heterochromatin binding, gene-regulation and its association with major TFs as well as chromatin remodeling and modifying enzymes. We however agree with the comment regarding the lack of direct effects of _Pf_MORC KD and have since provided additional evidence by performing ChIP-seq experiments against H3K9me3 and H3K9ac during KD. Our new results are presented in Fig. 5. We showed that the level of H3K9me3 decreased significantly during _Pf_MORC KD.
Furthermore, while numerous interacting partners have been identified, their validation is critical and understanding their role in directing MORC to its targets or in influencing the chromatin compaction activities of MORC is essential for further clarification. In addition, the authors should adjust their conclusions in the manuscript to more accurately represent the multifaceted functions of MORC in the parasite.
Validation of the identified interacting partners is indeed critical and essential to understanding their role in directing MORC to its targets. Our protein pull down experiments have been done using several biological replicates. Several of the interacting partners have also been identified and published by other labs and collaborators. To confirm our results, we completed a direct comparison of our work with previous published work. Results have now been incorporated into the revised manuscript to confirm the identified interacting partners and the accuracy of the data we obtained in our experiment. Molecular validation of novel proteins identified in our protein pull down requires generation of tagged lines and may take a few more years but will be submitted for publication in a follow up manuscript.
Reviewer #2 (Public Review):
Summary: This paper, titled "Regulation of Chromatin Accessibility and Transcriptional Repression by PfMORC Protein in Plasmodium falciparum," delves into the PfMORC protein's role during the intra-erythrocytic cycle of the malaria parasite, P. falciparum. Le Roch et al. examined PfMORC's interactions with proteins, its genomic distribution in different parasite life stages (rings, trophozoites, schizonts), and the transcriptome's response to PfMORC depletion. They conducted a chromatin conformation capture on PfMORC-depleted parasites and observed significant alterations. Furthermore, they demonstrated that PfMORC depletion is lethal to the parasite.
Strengths: This study significantly advances our understanding of PfMORC's role in establishing heterochromatin. The direct consequences of the PfMORC depletion are addressed using chromatin conformation capture.
We appreciate the Reviewer’s comments and reflection on the importance of our work.
Weaknesses: The study only partially addressed the direct effects of PfMORC depletion on other heterochromatin markers.
Here again, we agree with the reviewer’s comment and have performed additional experiments to delve deeper into the multifaceted roles of _Pf_MORC. We have performed additional ChIP-sequencing analysis on _Pf_MORC depleted conditions focusing on known heterochromatin and euchromatin markers H3K9me3 and H3K9ac respectively. We hope our new results presented in figure 5 will shed light on the more direct implications of _Pf_MORC on heterochromatin and gene silencing.
Reviewer #1 (Recommendations For The Authors):
Suggestions for improved or additional experiments, data or analyses.
• Why does MORC, which was used in the pull-down, seem to be only minimally enriched in the volcano plot, while a series of proteins (marked in red) and AP2 (highlighted in green) are enriched with log2 fold changes exceeding 15?
We apologize for the confusion. MORC was detected with the highest number of peptides (97 and 113) and spectra (1041 and 1177) confirming the efficiency of our pull-down. However, considering the relatively large size of the MORC protein (295kDa) and it weak detection in the control (5 and 7 peptides; 16 and 43 spectra), the Log2 FoldChange and Z-statistic after normalization are minimal compared to smaller proteins that were not identified in the control samples.
Additionally, can you explain why these proteins appear to be enriched at the same fold?
We can postulate that these proteins form a complex with a ratio of 1:1. Two of these three proteins are described to interact with MORC in several publications, supporting a strong interaction between them.
Variations in the interactome could result from the washing buffer's stringency.
We agree that the IP conditions could affect the detection of the interactome as well as the parasite stage used. As indicated below, the overlap with previous publications and the presence of AP2 TFs and chromatin remodelers strongly support our results.
It would be highly appropriate for the authors, similar to the co-submitted article (Maneesh Kumar Singh et al.), to present their mass spectrometry data in relation to previous purifications in Plasmodium (Bryant et al. 2020; Subudhi et al. 2023; Hillier et al. 2019) and also in Toxoplasma (Farhat et al. 2020). It would be good if authors could also put their results into perspective in light of the following pre-prints:
We agree with the reviewer’s comment. In this revised manuscript, we compared our IP-MS data to previous published manuscripts. Key proteins including the AP2-P (PF3D7_1107800) and HDAC1 were indeed identified in several experiments validating our initial findings of the formation of large complexes with MORC. However, it’s important to highlight that the MORC protein was not used as the bait protein in previously published papers, and thus some discrepancies can be observed.
Given the tendency of MORCs to form multiple complexes with AP2 factors, have you explored whether specific AP2s are conserved between Plasmodium and Toxoplasma, within the phylum?
P. falciparum encodes for 27 putative AP2s, while T. gondii has over 60 AP2s, making direct comparison challenging. Some Plasmodium AP2s have multiple counterparts in T. gondii and typically conservation is limited to the AP2 binding domains. Attempts to identify sequence homology among AP2s and the regions of conservation have been performed (PMID: 30959972, PMID: 30959972, PMID: 16040597). Although this information would provide interesting insight, we believe exploring this topic at this time would diverge from our primary objectives. It would be more appropriate to address this in future studies.
Could this conservation be identified either through phylogenetic means or by using tools such as AlphaFold, especially considering not just the AP2 domains but also any existing ACDC domains?
Although this may reveal important information regarding the association between MORC proteins and AP2 domains, we believe investigating the conservation between AP2 across apicomplexan parasites may prove too challenging and is beyond the scope of this work.
Most of the genes are depicted without their immediate surroundings (Fig. 2d and Fig S2c, d). For instance, the promoter region of AP2g is not shown (Fig. 2d). It is therefore very challenging to determine the presence or absence of MORC upstream or downstream; considering that this factor, which can create DNA loop protrusions, might bind at a distance from the genes in question.
All gene coverage plots, including AP2-G, show 500 bp up- and downstream of the displayed gene. We have modified our figure legends to make sure that this information is provided.
Upon examining Figure S3, it is evident that the authors have indicated a decline in PfMORC expression, represented as percentages over two unique time frames. The methodology behind this quantification remains ambiguous. It's essential for the authors to specify whether normalization was done using a loading control. As a benchmark, Singh et al. (2021) in their Figure 4 transparently used GAPDH as a loading control and included an untreated sample in their western blot analysis.
We thank the Reviewer for bringing this to our attention. Our initial quantification was performed using ImageJ. To address the Reviewer’s comment, we have reperformed the experiment. Our quantitative analysis was performed through Bio-Rad ImageLab software using aldolase expression as a loading control (50% of the MORC loading). This information has now been incorporated into the supplementary figures (Figure S3).
There's a striking observation that, despite significant degradation of PfMORC (as depicted in Figures S1 and S3), only the upper band in the western blot diminishes. This inconsistency needs addressing, as it can raise questions about the interpretation of the results.
We agree with the reviewer's comment. We experienced some challenges upon performing a Western Blot on such a large protein (295kDa). Our initial attempts required long exposure that may have highlighted non-specific signals of smaller proteins. To address the reviewer’s comment, we have performed the experiment one more time and made necessary changes to our WB protocol. Our new result better reflects the expected down regulation of _Pf_MORC. These changes have been incorporated to our manuscript and Fig S3.
Recommendations for improving the writing and presentation.
MORC KD quantification and consistency with previous findings (Figure S3): When comparing their results with those from another study (Singh et al. 2021), it's critical to ensure that the experimental conditions, especially the methodology for KD and the quantification of protein levels, are similar. If not, a direct comparison might be misleading.
We greatly appreciate the suggestions and have made efforts to redesign the MORC KD quantifications according to the reviewer’s recommendations.
While the manuscript mentions the level of KD, it does not delve into the functional consequences of such a decrease in protein levels. It would be of interest to understand how this level of KD affects the parasite's biology, especially in the context of the paper's main findings.
We have addressed this question by looking at the changes in chromatin structure in WT versus KD parasites upon atc removal. We have also validated this initial result by designing an additional ChIP-seq experiment against histone marks in WT versus KD parasites upon atc removal. Our findings showed a significant downregulation in H3K9me coverage in heterochromatin regions, specifically in genes associated with antigenic variation and invasion genes. These findings suggest that PfMORC regulates at least partially gene silencing and chromatin arrangements. The manuscript has been edited accordingly.
Concluding page 5, the authors present an interpretation of their findings that suggests a multi-faceted role of PfMORC in regulating stage-specific gene families, particularly the gametocyte-related genes and merozoite surface proteins. While the narrative they present is intriguing, several concerns arise:
Over-reliance on correlation: The authors draw a direct line between the levels of PfMORC binding and the function of these genes in the parasite's life cycle. However, a mere correlation between PfMORC binding and stage-specific gene activity does not necessarily imply causation. They would need to provide experimental evidence showing that manipulation of PfMORC levels directly impacts these genes' expression.
We agree with the reviewer's comment. We have however partially addressed this issue by comparing our ChIP-seq, RNA-seq and Hi-C experiments. We concluded that several of the transcriptional changes observed were due to an indirect effect of PfMORC KD and were most likely induced by a cell cycle arrest and partial collapse of the chromatin structure. The collapse of the heterochromatin structure was validated using our Hi-C experiment. To further address additional concerns the review’s had, we have included additional ChIP-seq experiments targeting histone marks to confirm our initial hypothesis. Result of this additional experiment has been incorporated in the revised version of the manuscript.
Ambiguity surrounding "low levels" and "high levels": The terms "low levels" and "high levels" of PfMORC binding are qualitative and could be subject to interpretation. Without quantification or a clear benchmark, these descriptions remain vague.
We agree with the reviewers that the terms "low levels" and "high levels" of PfMORC binding are qualitative and could be subject to interpretation. We have however quantified our change in DNA binding using normalized reads (RPKM). In trophozoite and schizont stages, most of the genes contain a mean of <0.5 RPKM normalized reads per nucleotide of Pf_MORC binding within their promoter region, whereas antigenic gene families such as _var and rifin contain ~1.5 and 0.5 normalized reads, respectively (Fig. 2b). Similar results are also obtained for the gametocyte-specific transcription factor AP2-G that contains levels of Pf_MORC binding similar to what is observed in _var genes (Fig. 2c and S2c, d).
Shift in Binding Sites: The observed minor switch in PfMORC binding sites from gene bodies to intergenic and promoter regions is mentioned, but without context on how these shifts impact gene expression or any comparative analysis with other proteins showing similar shifts. The claim that this shift implicates PfMORC as an "insulator" is a leap without direct evidence.
We apologize for the confusion. We have compared our ChIP-seq with RNA seq results at different time points of the cell cycle and demonstrated that the shift observed has an effect in gene expression. We have edit the manuscript to clarify these results.
Overextension of PfMORC's Role: The authors suggest that PfMORC moves to the regulatory regions around the TSS to guide RNA Polymerase and transcription factors. This is a substantial claim and would require additional experiments to validate. Simply observing binding in a region is insufficient to assign a specific functional role, especially one as critical as guiding RNA Polymerase. Historically, the MORC family has been primarily linked with gene silencing across Apicomplexan, plants, and metazoans. On page 7, the authors noted a minimal overlap between the ChIP-seq and RNA-seq signals (Fig. 4e). They also acknowledged that the pronounced gene expression shifts at schizont stages result from a combination of direct and indirect impacts of PfMORC degradation, which could cause cell cycle arrest and potential heterochromatin disintegration, rather than just decreased PfMORC binding. Therefore, the authors should adjust their conclusions in the manuscript to more accurately represent the multifaceted functions of MORC in the parasite.
We agree with the reviewer's comment and have edited the manuscript accordingly.
DISCUSSION:
The authors concluded that "Using a combination of ChIP-seq, protein knock down, RNA-seq and Hi-C experiments, we have demonstrated that the MORC protein is essential for the tight regulation of gene expression through chromatin compaction, preventing access to gene promoters from TFs and the general transcriptional machinery in a stage specific manner."
Again, the assertion that MORC protein is essential for tight regulation of gene expression, based purely on correlational data (e.g., ChIP-seq showing binding doesn't prove functionality), assumes causality which might not be fully substantiated. The phrase "preventing access to gene promoters from TFs and the general transcriptional machinery in a stage-specific manner" needs also validation. Asserting that MORC is essential for this function might oversimplify the process and overlook other critical contributors.
We agree with the reviewer’s comments and the conclusion has since been edited accordingly.
The discussion is quite poor. It would be pertinent to put MORC in perspective within the broader picture of regulatory mechanisms of chromatin state at telomeres and var genes. For instance, how do SIR2 and HDAC1 (associated with MORC) divide the task of deacetylation? Or the contribution of HP1 and other non-coding RNAs.
We agree with the reviewer’s suggestion. However, in order to put MORC in perspective within a broader picture, we would need to measure changes in localization of several molecular components regulating heterochromatin in WT versus KD condition. This will require access to several molecular tools and specific antibodies that we do not currently have. We have addressed these issues in our discussion.
Minor corrections to the text and figures.
Figure 1d: Could you provide the ID for each AP2 directly on the volcano plot? While some IDs are referenced in the manuscript, visual representation in the plot would facilitate a clearer understanding of their enrichment levels.
ID for unknown AP2 proteins have been added on the volcano plot.
I recommend presenting Figure S2b as a panel within a primary figure. This change would offer readers a more quantitative understanding of the distinct differences between developmental stages. Notably, there seems to be a limited number of genes in common when considering the total, and there is an apparent lack of enrichment in the ring stage.
This has been done.
The captions are very minimally detailed. An effort must be made to better describe the panels as well as which statistical tests were used.
We have improved the figure legends and add the number of biological replicates as well as the statistic used in each figure legend.
Figure 1A: The protein diagram with its domains does not take scale into account.
The figure has been modified.
Reviewer #2 (Recommendations For The Authors):
(1) The study lacks a direct link between PfMORC's inferred function and the state of heterochromatin in the genome post-depletion.
We agree with the reviewer's comment and have included additional ChIP-seq experiments to measure changes in histone marks in PfMORC depleted parasite line. We show a significant decrease in histone H3K9me3 marks in PfMORC KD condition.
Conducting ChIP-seq on well-known heterochromatin markers such as H3K9me3, HP1, or H3K36me2/3 could shed light on the consequences of PfMORC depletion on global heterochromatin and its boundaries.
With no access to an anti-HP1 antibody with reasonable affinity, we have not been able to study the impact of MORC KD on HP1 but have successfully observed the impact on H3K9me3 marks. These results have been added to the revised manuscript in (Fig. 5).
(2) The authors should conduct a more comprehensive analysis of PfMORC's genomic localization, comparing it to ApiAP2 binding (interacting proteins) and histone modifications. This would provide valuable insights.
We have performed a more comprehensive genome wide analysis of MORC binding through ChIP-seq on WT and MORC-KD conditions. Our results show that Pf_MORC localizes to heterochromatin with significant overlap with H3K9-trimethylation (H3K9me3) marks, at or near _var gene regions. When downregulated, level of H3K9me3 was detected at a lower level, validating a possible role of _Pf_MORC in gene repression. Regarding the comparison with AP2 binding, our proteomics datasets have shown extensive MORC binding with several AP2 proteins.
(3) RNA-seq data reveals that only a few genes are affected after 24 hours of PfMORC depletion, with an equivalent number of up-regulated and down-regulated genes. The reasons behind down-regulation resulting from a heterochromatin marker depletion are not clearly established.
We agree with the reviewer’s comment. At this stage (24 hours), _Pf_MORC depletion is limited and the effects at the transcriptional level are quite restricted. Furthermore, it is highly probable that down-regulated genes are most likely due to an indirect effect of a cell cycle arrest. We have edited the manuscript to address this comment.
The relationship between this data and the partial depletion of PfMORC needs further discussion.
We agree with the reviewers and have improved our discussion in the revised version of the manuscript.
(4) The authors did not compare their ChIP-seq data with the genes found downregulated in the RNA-seq data. Examining the correlation between these datasets would enhance the study.
We apologize for the confusion. We have compared ChIP-seq and RNA-seq data and identified a very limited number of overlapping genes indicating that most of the changes observed in gene expression are in fact most likely indirect due to a cell cycle arrest and a collapse of the chromatin. We have edited the manuscript to clarify this issue.
(5) The discussion section is relatively concise and does not fully address the complexity of the data, warranting further exploration.
We have improved the discussion section in the revised version of the manuscript.

"militarization" is limited in its ability to fully capture the violence of liberal order, as it fails to acknowledge that there is no "good" liberal civilian past to which we can retreat.
-
It implies that universities were once purely civilian institutions that have been encroached upon by military values.
militarisation ignores contexts that built institutions were built on war values
-
"militarization" framework elides: the historical context out of which the use of military equipment and tactics against Black activism develops.
limits of MILITARISATION as it excludes crucial contexts
-
militarization is a new process by which the exception (war) encroaches on the norm (peace).
-
The concept of militarization assumes a peaceful liberal order that is encroached on by military values or institutions, but this assumption is false.

¿Qué bendición recibieron Pablo y Silas por aguantar la persecución sin perder la alegría?
Que el carcelero y todos los de su casa fueron bautizados. Nos imaginamos la alegría que debieron haber sentido por el buen resultado que tuvo aquella injusticia.
-
a) ¿Cómo ayudaron Pablo y Silas al carcelero?
Le dedicaron tiempo “le predicaron la palabra de Jehová”. Sin preocuparse por el dolor de las profundas heridas que tenían en la espalda. Pero el carcelero sí se fijó en ellas y se puso a limpiárselas.
-
¿Qué situación llevó al carcelero a preguntar qué debía hacer para salvarse?
En determinado momento de la noche mientras Pablo y Silas cantaban alabanzas, hubo un terremoto y las puertas de la prisión se abrieron. El carcelero al pensar que se habían escapado, intentó quitarse la vida para evitar el castigo que se imaginó. Pero Pablo le hablo y dijo que estaban ahí. Éso seguramente lo conmovió el mismo los saco y le realizó esa pregunta. Hechos 16:25-31

b) ¿Qué tácticas siguen usando contra nosotros Satanás y la gente que actúa bajo su influencia?
Las mismas que en aquel momento, usan mentiras para fomentar el odio y la Opcion, debido al nacionalismo. O tradiciones. Por lo que muchos hermanos terminan golpeados o en prisión. Lo bueno es que Jehová está al tanto de todo éso 1 Pedro 3:12 dice que nada está escondido a Jehová y que además el escucha el ruego de los justos.
-
a) ¿Cómo veían Pablo y sus compañeros la persecución, y por qué?
Cómo una señal que Jehová estaba contento con su obra. ellos estaban advertidos y recordaban las palabras de Jesús acerca de que Satanás se enojaría, y los atacaría. Juan 15:20
-
. ¿Qué les pasó a Pablo y Silas después de expulsar al demonio?
Los amos de la Joven perdieron una fuente de ingresos, así que tomaron venganza, y empezaron hablar mal de Pablo y Silas, y los arrastraron ante jueces que tenían prejuicios, así que mediante acusaciones falsas, los encerraron en un calabozo muy oscuro y con cepo en los pies. Hechos 16:19-24
-
¿Qué hicieron los demonios para tratar de detener a Pablo y sus compañeros?
Hicieron lo posible para distraerlos intentando detener su predicación, en una ocasión, un demonio los molestaba diciendo que Pablo y sus compañeros eran enviados por Dios, aunque éso era verdad. Era una molestia para Pablo y por supuesto distraía a las personas, nos imaginamos a los hermanos hablando normal y está joven gritando cerca de ellos? Hechos 16:16-18

I long to hear that you have declared an independancy—and by the way in the new Code of Laws which I suppose it will be necessary for you to make I desire you would Remember the Ladies, and be more generous and favourable to them than your ancestors. Do not put such unlimited power into the hands of the Husbands. Remember all Men would be tyrants if they could. If perticuliar care and attention is not paid to the Laidies we are determined to foment a Rebelion, and will not hold ourselves bound by any Laws in which we have no voice, or Representation.
Reflects Abigail's eagerness for Americas independence from British rule. She explicitly asks John to consider women in the legislative process, indicating an early demand for women's inclusion in lawmaking. She also critiques traditional views on marriage and the power held by husbands over their wives. Abagail presents a bold statement about the potential for men to abuse power, highlighting the need for checks and balances Her warning implies that women are ready to rise against oppression, similar to the colonies fight against British rule .The closing assertion is a direct demand for inclusion and rights, emphasizing the importance of representation in governance. Abigail Adams' letter is foundational text in the discourse about women's rights and representation during the American Revolution. The themes highlighted through this annotation process illustrate her advocacy for gender equality ,critique of existing power structures, and demand for women's voices in the political arena. This letter not only reflects the historical context of the time but also resonates with contemporary discussions about gender rights and representation.

Reflectors, uniquely, have a very close relationship with the moon. They live in a time zone all their own. It is a lunar cycle time zone. It is this closeness to the moon that offers the Reflector an ability to make decisions reliably. But in order to be correct the Reflector needs to wait out the entire 28 day lunar cycle before making a decision. And of course this is a very difficult thing to do!

3.6. CONCLUSÃO
Deixo só um último comentário onde acho que esta maneira de analisar um documento em conjunto, assim como o software da semana passada onde analisámos um vídeo em conjunto são plataformas que eu desconhecia mas que acredito terem um grande potencial pois fazem com que trabalhos mundanos fiquem mais divertidos com o conjunto de ideias que são partilhados por todos!

Para que tal aconteça é importante quese verifique uma correta adequação entre os conteúdos e a atividadeproposta; é igualmente pertinente que os alunos percebam a utilidade daatividade para a sua aprendizagem e que a mesma seja clara; é tambémrelevante que as atividades propostas ao longo da ação formativa sejamdiversificadas e estejam de acordo com o nível educativo dos alunos;
Este ponto é um que eu considero que muitos formadores deixam de fora, é muito importante que alunos percebam porque estão a ser avaliados! Muitas pessoas, incluindo eu, não funcionam com base no porque sim. E conseguirmos explicar os motivos da avaliação e mostrar-lhes que se feita de uma forma adequada e correta é benéfica para todos, especialmente para eles, será uma grande ajuda para que o processo de avaliação corra de maneira positiva, promovendo a evolução dos alunos.

In a fashion similar to Western Zen’s ontology of the self, the entrepreneurial person engages in a twin project of subjectification and desubjectification, i.e. deconstructing an illusionary understanding of the self and making room for a more flexible and even foundationless identity
ok - now the connection is explicit!
The question remains, though: how much desubjectification is necessary?

the entrepreneurial self is a figure who is perfectly liquid
DING! --This relates explicitly to the claims made about “liquid society” in the “Unconventional entrepreneurship” article. It also relates implicitly to the claims made about entrepreneurship in the article, “‘Don't forget to like, share and subscribe’: Digital autopreneurs in a neoliberal world.” But whereas this latter article discusses “figures” that do not appear perfectly content in their management of their entrepreneurial selves, Saari and Harni seem to suggest mindfulness and a ‘spiritual’ relationship to one’s environment as a transcendent (or tactical) move that empowers entrepreneurial, flexible individuals in their journeys toward self-fulfilment. Clearly, there are many links between entrepreneurial adult education and the “world-affirming” insights it offers and the themes of the previous weeks we’ve examined in this course.

mindfulness meditation
-
t has become a commonplace, for example, to say that if a person thinks positively, he/she actually becomes positive, happy person.
somewhat redressed by last week's content...
And how does this incessant happiness gel with the zen-like attitude of the following:
-
mindfulness as a meditative practice of non-judgmental focus on the present moment
-
world-affirming action in everyday life. Acting in the Zen way in quotidian life is always effortless and flexible,
-
. Learning to foster a calm mind will help you become a better entrepreneur.
Fostering a peaceful disposition:
-
ntrepreneurial ethos, therefore, deals with idea of a person who is self-satisfied, and more specific, someone who produces her own satisfaction and happiness
ok... but the zen-like peace gets displaced by the entrepreneurial ethos that says you always have to be working (in order to produce your own happiness):
-
Drawing from Zen Buddhism, the entrepreneurial celebration of mindfulness highlights its ability to cultivate creativity, intuitive and flexible action and learning to learn. I

oth Zen and entrepreneurial discourse in general can be traced back to a tradition of criticism of the nexus of positivist psychology and Taylorist management practices

mindfulness as emancipating...
-
capitalism does not only ‘repress’ in the sense of suffocating human life, but creates human reality and cultivates it productive forces
ends off with a strangely positive-sounding note...
-
the way Zen spirituality is used in entrepreneurship education shows the inventive sweeping logic of capitalism:
...
-
person practicing mindfulness is not attached to the future nor the past, but focuses stringently on the present moment only.
how do you think this accords with entrepreneurial thinking? Clearly, one ought not be wrapped up in the past (either failures or successes), but what about a future-focus? A fixed mindset is clearly bad, but is a growth mindset also (especially if the pressure to "grow" and "develop" takes one away from a present focus)?
-
Through learning to control one’s self through mindfulness meditation, an entrepreneurial person can have a deeper, healthier relation to her own affects and bodily well-being
ok... last week's emphasis on (happiness and subjective) well-being blends with this focus on wellness and bodily well-being
-
lements from Western Zen Buddhism have also been added to limn the contours of the spiritual aspects of work.
to limn = to depict/describe (from the root word "illuminate")
-
e countercultural and at times decidedly anti-capitalist ethos of Zen Buddhism was deterritorialized and annexed to the very conditions of productive work in general economy.
this isn't the original "zen"
-
e very notion of subjectivity now assumes a liquidity or ‘emptiness’, as there is seemingly nothing stable and unchanging in the ideal entrepreneur.

y practicing mindfulness, one supposedly learns not to falter into emotional reactions to surprising adversities, but retain clear-headedness and self-control

Being a holistic entrepreneur means there is no separation between your love, life, work and spirituality.

-
ne should even let go of the very notion of trying to achieve something through mindfulness practice.
Wow - this sounds, at first, like it's antithetical to entrepreneurial undertakings. Shouldn't one want to achieve something and invest oneself wholly in it?
-
mindfulness can enable entrepreneurs to minimize errors and remain vigilant. F

-
the dynamics of cognitive, conative and affective constructs and meta-level self-regulating abilities are crucial in achieving entrepreneurial behavior and an entrepreneurial mindset.
indeed - this is a summation of the relevance of the last number of weeks, connected under the rubric of "mindset."
FYI - cognitive relates to thinking, affective relates to emotions, and conative relates to behaviour, specifically the inclination to act 'on purpose'. It's an effort or a drive to do something, but this isn't entirely rational...
-
This resonates well with the aforementioned ontological ramifications of spirituality in Western Zen Buddhism, where the self is decidedly empty, i.e. not fixed in its delusions of stable identity.
what a link - liquid selves in an entrepreneurial context = zen-like...
-
Entrepreneurial mindfulness discourses entail meticulous descriptions on how to calm the mind by focusing on the present moment.
...
-
self-regulation refers to an individual’s active participation in his or her own learning process
very eudaimonic!
-
There is a large amount of self-help literature, websites, courses and self-evaluation measurement tools in which entrepreneurs and those who strive for an entrepreneurial mindset in their everyday lives are encouraged to develop themselves as persons, to seize the day, to learn to rule their thoughts and to cope with increasing uncertainty.
zen is awfully implied here - not at all explicit.
