    1. Your sources will include both primary sources and secondary sources. As you conduct research, you will want to take detailed, careful notes about your discoveries. These notes will help trigger your memory about each article’s key ideas and your initial response to the information when you return to your sources during the writing process. As you read each source, take a minute to evaluate the reliability of each source you find.

      One of the most important parts of research is taking careful notes about your discoveries. It will trigger your memory about the key points of each of the articles. Make sure to evaluate the reliability of every source you use.

    2. The challenge here is to conduct your search efficiently, so writers use strategies to help them find the sources that are most relevant and reliable while steering clear of sources that will not be useful.

      Searching efficiently you can decide what source is the most relevant. Narrowing down your options.

    3. Your topic and purpose determine whether you must cite both primary and secondary sources in your paper. Ask yourself which sources are most likely to provide answers your research questions. If you are writing a research paper about reality television shows, you will need to use some reality shows as a primary source, but secondary sources, such as a reviewer’s critique, are also important. If you are writing about the health effects of nicotine, you will probably want to read the published results of scientific studies, but secondary sources, such as magazine or journal articles discussing the outcome of a recent study, may also be helpful.

      Depending on your topic you will decide if you will use primary as well as secondary sources. Which one is more beneficial and can provide answers to my research paper?

    4. Secondary sources discuss, interpret, analyze, consolidate, or otherwise rework information from primary sources. In researching a paper about the First Amendment, you might read articles about legal cases that involved First Amendment rights or editorials expressing commentary on the First Amendment. These sources would be considered secondary sources because they are one step removed from the primary source of information. The following are examples of secondary sources: Magazine articles Biographical books Literary and scientific reviews Television documentaries

      Secondary sources as well as examples of other articles you could use.

    5. Other primary sources include the following: Research Articles Literary Texts Historical documents such as diaries or letters Autobiographies or other personal accounts Podcasts

      Other primary sources used for sourcing

    1. Solías empezar la universidad con un curso de estructuras de datos, con listas enlazadas, tablas hash y demás, con un uso extensivo de punteros. Esos cursos solían usarse como descarte: eran tan difíciles que cualquiera que no pudiera afrontar el reto mental de una licenciatura en Ciencias de la Computación lo abandonaba, lo cual era bueno, porque si pensabas que los punteros son difíciles, espera a intentar demostrar algo sobre la teoría del punto fijo.

      ¿Qué crítica realiza sobre la forma en que se enseña programación?

    2. Java no es, en general, un lenguaje de programación lo suficientemente complejo como para distinguir entre buenos y malos programadores.

      ¿Cuál es la idea principal que plantea el autor en el artículo?

    1. specialize in rice and could easily export it on boats

      Different places specialized in different things showing the need for trade and exchanging goods. This way the food that was eaten in a place does not limit to the food that is specialized to that place.

    2. worked by African slaves

      This shows how much labor and force were on the slaves. Slavery was the backbone of a lot of trade and that is what fueled the slave owners to be so stern on them and force them to labor on.

    3. working families spent 60 to 80 percent of their earnings on food

      One thing has always stayed the same throughout history, working helps families and individuals feed and care for themselves. Working is not for just luxury goods, but about maintaining basic health too.

    4. The use of coal-fired steam to power machines was a major breakthrough, launching human society out of the biological old regime and into a new one no longer limited by annual solar energy flows

      This shows the breakthroughs that happen in history due to discovery. Learning how to manipulate natural products can benefit societies and advance living that impacts history from then on.

    1. that a single shelf of a good European library was worth the whole native literature of India and Arabia.

      This statement doesn't acknowledge non-European knowledge.

    2. It would be, on the most selfish view of the case, far better for us that the people of India were well governed and independent of us, than ill governed and subject to us

      Macaulay frames British interest as compatible with Indian independence, his is reasoning is economic (better trading partners).

    1. OK: I went to the University of Washington and [then] I got hired by this company called Geoworks, doing assembly-language programming, and I did it for five years. To us, the Geoworkers, we wrote a whole operating system, the libraries, drivers, apps, you know: a desktop operating system in assembly. 8086 assembly! It wasn't even good assembly! We had four registers! [Plus the] si [register] if you counted, you know, if you counted 386, right? It was horrible.I mean, actually we kind of liked it. It was Object-Oriented Assembly. It's amazing what you can talk yourself into liking, which is the real irony of all this. And to us, C++ was the ultimate in Roman decadence. I mean, it was equivalent to going and vomiting so you could eat more. They had IF! We had jump CX zero! Right? They had "Objects". Well we did too, but I mean they had syntax for it, right? I mean it was all just such weeniness. And we knew that we could outperform any compiler out there because at the time, we could!So what happened? Well, they went bankrupt. Why? Now I'm probably disagreeing – I know for a fact that I'm disagreeing with every Geoworker out there. I'm the only one that holds this belief. But it's because we wrote fifteen million lines of 8086 assembly language. We had really good tools, world class tools: trust me, you need 'em. But at some point, man...The problem is, picture an ant walking across your garage floor, trying to make a straight line of it. It ain't gonna make a straight line. And you know this because you have perspective. You can see the ant walking around, going hee hee hee, look at him locally optimize for that rock, and now he's going off this way, right?This is what we were, when we were writing this giant assembly-language system. Because what happened was, Microsoft eventually released a platform for mobile devices that was much faster than ours. OK? And I started going in with my debugger, going, what? What is up with this? This rendering is just really slow, it's like sluggish, you know. And I went in and found out that some title bar was getting rendered 140 times every time you refreshed the screen. It wasn't just the title bar. Everything was getting called multiple times.Because we couldn't see how the system worked anymore!

      This is a well-known passage by Yegge explaining why GeoWorks didn't attain success with their object-oriented assembly, and why their object-oriented assembly is the reason for not doing so.

      A pithier and more succinct analogy of the bigger picture that Yegge is trying to communicate here—something like what Engelbart struggled to get people to understand resulted in his metaphor of a pencil taped to a brick—would be, "There's a reason why programmers aren't writing code on punch cards anymore (and it's not just because the market for the equipment and, accordingly, the equipment itself, all but vanished and is no longer available)."

    1. Consider correlated scenarios via the maturity slider

      We probably want to unpack this more. One could imagine some forms of technical development going together and others less so.

    2. At 20 kTA reference scale

      Still needs more explanation. I don't know why you're using this reference scale. I don't know why we're talking about farmer grade, etc.

    3. Weighted average cost of capital

      That seems rather high - what are references for this? Why should it be so expensive? Here, is this comparable to some benchmarks?

      And again, I want to be able to look up each of these elements within an equation somewhere - I don't see where that equation is. Make the links clearer.

    4. Breakthrough technologies that could trigger the “cheap” scenario: - Autocrine cell lines (cells produce own FGF2) - Plant molecular farming ($1-10/g target) - Precision fermentation at scale - Polyphenol substitution (reduces GF requirements by 80%)

      Okay, you got to my question here that I asked above, although it still seems underexplained. Wouldn't each of these things have independent effects on the cost of growth factors? So why is it just a zero-one switch?

    5. 30-200 g/L Final biomass at harvest Cycle time 0.5-5 days Time per production batch Media turnover 1-10 ratio 1=batch, >1=perfusion

      Interesting, but it should be more clear how this maps into the ultimate cost equation. Everything should be linked back in some way to a total cost formula. I'd like to be able to open and close and unpack the different elements.

    6. Scalable GF technology 50% Switches to “cheap” GF prices Pivotal uncertaint

      As mentioned elsewhere, this needs a lot more explanation or discussion. What is the major factor switching us between cheap and expensive growth factors here? How much does this affect the outcomes? What are the different price distributions for the cheap versus expensive ones? I'm not actually seeing growth factors or any of these p's in any of the equations you give. At least not in a way that allows me to unpack each element.

    7. Why correlate? In “good worlds” for cultured chicken: - Technologies are more likely adopted (higher P) - Custom reactors are more common (lower CAPEX) - Financing is cheaper (lower WACC) This prevents unrealistic scenarios where technology succeeds but financing remains prohibitively expensive.

      this is really not well explained. I don't see how the discussion relates to the equations here

    8. The model uses a latent maturity factor (0–1) to correlate technology adoption, reactor costs, and financing: Padopted=bound(Pbase+k⋅(m−0.5),0,1) What does “bound” mean? bound(x, 0, 1) ensures the result stays between 0 and 1. Also c

      what are k and m here? define and explain

    9. The GF progress slider interpolates between current and target prices: PGF=Pcurrent×(0.01)progress At 0% progress: current prices ($5,000–500,000/g) At 100% progress: target prices ($1–100/g for cheap scenario)

      The equation doesn't seem to be correct/displayed correctly here. Explain more but also I don't understand what "0.01^(progress)" means

    10. Example calculation: - Cell density: 50 g/L → need 1000/50 = 20 L per kg - Media turnover: 3× (perfusion system) → 20 × 3 = 60 L/kg - Media price: $0.50/L (hydrolysates) → 60 × 0.50 = $30/kg

      is the 'per liter' meaningful though? Doesn't the density depends strongly on the contents used?

    1. In what ways do you think you’ve participated in any crowdsourcing online?

      I think I was a more active participant of crowdsourcing online when I was younger, but am now a lurker on essentially website I do use. When I was younger I was an active member of my communities, raising awareness, and even doing small events for designers which got donations. Now, I just scroll on my own private accounts ranging from 0-70 followers and like what I enjoy. I sometimes still donate money (crowdfunding), and I buy merch from posts in my fandom communities.

    1. Emergent and self-sustaining: Communities creating and spreading their own rumors or own conspiracy narratives.

      Can this be harmful even if it is framed as a joke? One example that instantly came to my mind is a running joke that women shed their skin once a month as well, to make fun of people (predominantly men) who are unaware of how the female body actually works and functions. Typically videos like this go viral, and most people in the comments section are in on the joke, with the occasional reply being someone unaware asking if everyone is being serious. I never found this harmful, but I'm wondering if it is because I always understood that it is a joke poking at unawareness. Can this cause people to feel inferior for not understanding?

      this stat is presented as if "connecting with coworkers on social media" = "social media presence in a professional context."

    1. first-person narration, third-person limited narration, and third-person omniscient narration.

      Different types of point of view

    2. The argument is narrated in direct speech, suggesting an authentic recreation of the actual incident, but is followed by a piece of narration by Stevens that immediately undermines our trust in his version of events:

    1. Some online platforms are specifically created for crowdsourcing. For example: Wikipedia: Is an online encyclopedia whose content is crowdsourced. Anyone can contribute, just go to an unlocked Wikipedia page and press the edit button. Institutions don’t get special permissions (e.g., it was a scandal when US congressional staff edited Wikipedia pages), and the expectation that editors do not have outside institutional support is intended to encourage more people to contribute. Quora: An crowdsourced question and answer site. Stack Overflow: A crowdsourced question-and-answer site specifically for programming questions. Amazon Mechanical Turk: A site where you can pay for crowdsourcing small tasks (e.g., pay a small amount for each task, and then let a crowd of people choose to do the tasks and get paid). Upwork: A site that lets people find and contract work with freelancers (generally larger and more specialized tasks than Amazon Mechanical Turk. Project Sidewalk: Crowdsourcing sidewalk information for mobility needs (e.g., wheelchair users). 16.2.2. Example Crowdsourcing Tasks# You probably already have some ideas of how crowds can work together on things like editing articles on a site like Wikipedia or answer questions on a site like Quora, but let’s look at some other examples of how crowds can work together. Fold-It is a game that lets players attempt to fold proteins. At the time, researchers were having trouble getting computers to do this task for complex proteins, so they made a game for humans to try it. Researchers analyzed the best players’ results for their research and were able to publish scientific discoveries based on the contributions of players.

      These examples show that crowdsourcing can be used for a wide range of work, from knowledge-sharing and freelancing to scientific research and accessibility projects. They also show that crowdsourcing is most powerful when platforms are designed well so many small contributions can be organized into something genuinely useful.

    1. When looking at who contributes in crowdsourcing systems, or with social media in generally, we almost always find that we can split the users into a small group of power users who do the majority of the contributions, and a very large group of lurkers who contribute little to nothing. For example, Nearly All of Wikipedia Is Written By Just 1 Percent of Its Editors, and on StackOverflow “A 2013 study has found that 75% of users only ask one question, 65% only answer one question, and only 8% of users answer more than 5 questions..” We see the same phenomenon on Twitter: Fig. 16.3 Summary of Twitter use by Pew Research Center# This small percentage of people doing most of the work in some areas is not a new phenomenon. In many aspects of our lives, some tasks have been done by a small group of people with specialization or resources. Their work is then shared with others. This goes back many thousands of years with activities such as collecting obsidian and making jewelry, to more modern activities like writing books, building cars, reporting on news, and making movies.

      This shows that social media participation is very uneven, with a small group producing most of the content while most users mostly read or watch. That pattern is not unique to the internet, but on social media it matters because the views and behavior of power users can shape what everyone else sees.

    1. The habit is very general among rich men and officials in China, but not so much among poor men. I don’t think it does as much harm as the liquor that the Americans drink. There’s nothing so bad as a drunken man. Opium doesn’t make people crazy.

      I found this observation to be interesting as it predates the prohibition movement, but mirrors some of the same sentiments. This outside view of American drinking culture vs. China's opium use is interesting as they are most likely both abused and used as a form of escapism for the user.

    2. You have expended a lot of the Public money foolishly, all because of a one poor little Child.

      The San Francisco school board's decision to spend taxpayer money on a new school rather than letting Tape into the school shows the prejudice they faced. I would be interested to know how common of solution this would become across the nation before the ruling of Brown V. Board.

    3. What right have you to bar my children out of the school because she is a chinese Decend. They is no other worldly reason that you could keep her out, except that

      I found this portion of Tape's writing to be interesting. Today, we have FAPE (free and appropriate education) guidelines that every school must abide by. I'm interested in whether her writing and similar ones of discrimination influence more well-known education law such as Brown v. Board and ADA (Americans with Disabilities Act)

      Important distinction

    1. Primary care is the first contact that a patient has with the health system when they have a health problem.

      Hello Class! I have chosen to talk about primary care because it is the first step and arguably the most important. Primary care is when we first meet the patient when they are experiencing a health related issue. The main goals of primary care is to prevent new illness, manage any chronic illness, and promote a healthy and active lifestyle. There is a very large team that can participate in primary care. Physicians including doctors and nurse practitioners, nurses, social workers, and medical assistants. Everyone can be seen in the primary care setting as it is the go to. Think of your doctors office and what you witness that goes on onside of it. They perform regular immunizations, monitor and treat minor issues, and education patients on the simple things such as diets. Other places that offer primary care are local health clinic, urgent care, and newly Telehealth. Payments sources that we will commonly see especially in our location is medicare for the elderly population and medicaid for low income. Primary care is our first look at a patient to determine what issues they might be facing which is why I think it is the most important. What do you think is the most common age population that visits the doctors office for primary care? Why do you think they are visiting so often? Thank you, Morgan Wagner

    1. Since numerous tumors have been shown to originate from tissue stem cells (Visvader, 2011), it has been proposed that CACs are the cell of origin for PanINs and PDA (Miyamoto et al., 2003; Stanger et al., 2005). However, this contention has not been directly tested, largely because genetic tools to target ductal and CACs have only recently been generated (Kopp et al., 2011; Solar et al., 2009).

      CAC's are cells that promote tissue regeneration and stem cells. These CAC's are proposed to be the cell origin for PanINs and PDA. This would make sense as these cells have increased proliferation in mice that lack the tumor suppressor gene (Pten). It is stated that not a lot of research has been done on that hypothesis, but it seems promising for understanding this cancer's origin.

    2. However, it is still unclear whether ADM and PanINs primarily arise by expansion of ductal cells and secondary replacement of acinar cells or by direct reprogramming of acinar cells into cells with ductal morphology.

      This sentence defines the central question of the study. Although pancreatic ductal adenocarcinoma has ductal morphology, it remains unclear whether precursor lesions arise from true ductal cells or from acinar cells that undergo reprogramming. The authors test whether oncogenic KRAS expands existing ductal cells or instead drives acinar cells to adopt a duct-like state through factors such as Sox9. Defining this distinction is essential for identifying the true cell of origin in PDA.

    1. Interestingly, these tumors did not manifest mutations in any of the other TSG pathways noted above. This raises the question of whether other TSG mutations alter the biology of the disease. For example, additional mutations may be required to develop a significant metastatic burden.

      Noting that none of the other TSG pathways were mutated in these tumors shows how little we actually can prove about PDA. This cancer can have many mutations that accelerate the disease and we aren't truly sure what mutation combinations are the cause of this cancer's aggressiveness.

    2. However, such molecular compendia are necessarily speculative and cannot distinguish causal from coincident events, nor which combinations of events might be required to establish disease.

      This sentence highlights the main scientific problem the study is addressing. Just because mutations like KRAS and TP53 are commonly found in pancreatic cancer does not prove they are sufficient or that they must occur together to cause disease. Observing mutations in patient samples cannot determine causation. Therefore, the authors use a genetically engineered mouse model to systematically test whether combining KrasG12D and Trp53R172H is enough to drive invasive and metastatic PDA.

    1. why content management systems were adopted on the Web. What you need is a way of getting to the HTML typing something easier to read and type. You need a simple way to manage the website structure for what you have written. Again there are programs that do this today. Unfortunately many are complex and come with their own steep learning curve.

      So document the process for updating the site in an SOP, making sure they're written in sufficient detail to be executable (by an agent—a user agent—sans LLMs), and then host the documents that detail those procedures on your site, as first-class content.

      "Updating the site" then entails 1. consulting the SOP, and 2. carrying out the procedure there (either manually, or having your agent do it).

      This is all achievable on a static site, provided there are Web-accessible (and, ideally, CORS-enabled) endpoints to control what content appears there (like the GitHub API, to name one example).

    1. Each piece is important, but without the bigger picture for reference, you and anyone watching will have a hard time understanding what is being assembled.

      This is true because if not analyzing well it leads to confusion.

    1. On the other hand, while Kant accepts killing animals—perhaps thinking of our food, although he doesn't explicitly say so—he imposes two very "human" restrictions: their death must be quick and painless (90). In this sense, our author would condemn the deplorable conditions in which animals are kept today on factory farms and the way they die to satisfy the market demand for meat. Kant would even oppose the slaughter of animals to please carnivorous humans, since, as we have already seen, no human desire justifies animal suffering. For this reason, we agree with Matthew Altman when he states that the ultimate consequence of Kant's stance against the cruel death of animals would be to adopt a vegetarian diet (91).
    1. Social information processing (SIP) theory’s chief claim is this: People can build interpersonal relationships despite the limitations imposed by mediated channels. SIP’s close cousin, the hyperpersonal model, goes a step further: Sometimes, mediated communication is even more satisfying than face-to-face communication. As I (Andrew) write this in the midst of the COVID-19 pandemic, these assertions feel very relevant and, honestly, a bit comforting. After all, the virus forced so many face-to-face interactions into technological means of communication. SIP helps us understand why that often works out just fine.

      This paragraph stood out to me because it shows how people can still build close relationships even when they aren’t communicating face-to-face. I think this connects to social penetration theory because relationships grow when people share more personal information over time, and that can still happen through texting or social media. Even if technology limits things like body language or tone of voice, people can still get to know each other by communicating regularly and opening up more. The part about COVID-19 makes this feel realistic because a lot of relationships had to move online, but people still stayed connected. The hyperpersonal model is also interesting because it suggests online communication can sometimes make relationships feel even closer, which might be because people feel more comfortable sharing personal things. Overall, this paragraph shows that relationships can still develop as long as people keep sharing information and communicating.

    1. Those who deal with death,” writes Lesy,“work at an intersection of opposites, tainted by the suffering and decay of the body,transfigured by the plight of the self and the destiny of the soul.”1

      I found this quote quite resonant, highlighting the inherent tensions in the activity of preservation. Though, I don't know if I agree with what the author says in the following passage regarding archivists being in the business of saving souls! In my estimation, an archivist is more like a shepherd, a docent, or perhaps, to use a million dollar word, an interlocutor between life and death, between the past and present (and so too the future). The article also made me think about hospices, of course, and the philosophy of palliative care - how one passes from this life to the next, with what dignity, in what repose. Moreover, the quote draws, for me, an important analogy between material objects and the temporal body - how one is, in effect, substituted for the other, allowing this transfiguration, as the author puts it.

    1. Le TDAH : Entre Trouble Neurodéveloppemental et Neurodivergence

      Résumé Exécutif

      Ce document propose une synthèse des connaissances actuelles et des débats entourant le Trouble du Déficit de l'Attention avec ou sans Hyperactivité (TDAH).

      Longtemps considéré comme une pathologie exclusivement infantile, le TDAH est désormais reconnu comme un trouble persistant à l’âge adulte, touchant environ 2,5 % de cette population.

      Le cœur du débat oppose une vision purement clinique, centrée sur le traitement des symptômes (inattention, agitation, impulsivité), à une approche basée sur la neurodiversité, percevant ces différences comme des atouts potentiels pour la société.

      Bien que le traitement médicamenteux (méthylphénidate) reste le plus efficace pour réduire les risques de mortalité et améliorer le quotidien, l'adaptation de l'environnement social et professionnel apparaît comme un levier crucial pour l'intégration et le bien-être des personnes concernées.

      --------------------------------------------------------------------------------

      1. Définition et Nature du TDAH

      Un trouble de la régulation de l'attention

      Le TDAH ne se définit pas par une absence totale d'attention, mais par une difficulté à la réguler.

      Il se manifeste par :

      Une distractibilité marquée : Difficulté à rester concentré sur des tâches routinières ou ennuyeuses.

      Une agitation motrice : Un besoin constant de mouvement, parfois intériorisé.

      Une impulsivité : Des réactions spontanées difficiles à cadrer.

      Une variabilité attentionnelle : L'attention est souvent détournée de son objet initial vers des stimuli environnementaux que le cerveau ne parvient pas à filtrer.

      La perspective de la neurodivergence

      Le concept de neurodiversité, formulé en 1998 par Judy Singer, postule qu'aucun cerveau n'est identique.

      Dans ce cadre, la neurodivergence désigne un fonctionnement cérébral s'écartant de la moyenne.

      Le Professeur André Zimpel suggère que le TDAH pourrait être perçu comme un "système d'alarme" pour la communauté, signalant un excès de monotonie ou de sédentarité dans notre environnement moderne.

      --------------------------------------------------------------------------------

      2. Diagnostic et Évolution Démographique

      Un sous-diagnostic chez l'adulte

      Bien que les cas recensés augmentent, le TDAH reste largement sous-diagnostiqué chez les adultes.

      Estimation : 2,5 % des adultes sont concernés.

      Le cas spécifique des femmes : Le diagnostic est souvent plus tardif chez les filles (comme l'illustre le parcours de Vanessa Bolk, diagnostiquée à 28 ans).

      Elles présentent souvent un "TDAH caché" car elles développent de meilleures capacités d'adaptation sociale, bien que le sentiment de chaos intérieur persiste.

      Historique de la perception clinique

      | Année | Évolution de la conception | | --- | --- | | 1844 | Heinrich Hoffman décrit l'instabilité motrice chez l'enfant. | | 1902 | Frédéric Schtill lie les symptômes à un "dysfonctionnement cérébral minimal". | | 1980 | Le terme officiel "TDAH" s'impose. | | Actuel | Reconnaissance du trouble comme une condition permanente et non uniquement infantile. |

      --------------------------------------------------------------------------------

      3. Impacts Sociaux et Risques Sanitaires

      Conséquences sur le parcours de vie

      Le TDAH non pris en charge peut mener à des trajectoires de vie difficiles :

      • Échecs scolaires et abandons de formations professionnelles.

      • Sentiment de rejet et "blessure narcissique" (impression de ne pas être aimé sans traitement).

      • Vulnérabilité accrue à la dépression, au burnout et à l'anxiété.

      Santé et espérance de vie

      Des données récentes indiquent une réduction de l'espérance de vie de 7 à 8 ans chez les personnes atteintes de TDAH.

      Cette surmortalité s'explique par :

      • Un risque accru d'accidents et de suicides.

      • Des facteurs de risque comportementaux : tabagisme précoce, consommation d'alcool, troubles alimentaires menant au surpoids.

      • Des maladies cardio-vasculaires liées au stress chronique de l'inadaptation.

      --------------------------------------------------------------------------------

      4. Stratégies de Traitement et de Prise en Charge

      Le traitement médicamenteux

      Le méthylphénidate (connu sous le nom de Ritaline) est un stimulant du système nerveux central.

      Paradoxalement, il aide les personnes hyperactives à se calmer en leur permettant de mieux cadrer leur impulsivité et de lutter contre une "fatigue" liée à la monotonie.

      Efficacité : Supérieure à la psychothérapie seule pour les symptômes primaires.

      Bénéfices : Réduction documentée des accidents et des suicides (études scandinaves).

      Effets secondaires : Troubles du sommeil, de l'appétit et mains froides.

      Innovations et thérapies alternatives

      Stimulation cérébrale par courant continu : Une méthode de recherche visant à modifier la communication entre les cellules nerveuses pour améliorer l'attention (séances d'environ 21 minutes).

      Psychothérapie comportementale : Utile pour gérer les conséquences psychologiques et organiser le quotidien, bien que moins efficace que les médicaments sur le déficit attentionnel pur.

      Activité physique : Recommandée comme régulateur naturel.

      --------------------------------------------------------------------------------

      5. Le TDAH comme Atout pour la Société

      Malgré les difficultés, les profils TDAH possèdent des compétences inestimables dans des contextes spécifiques :

      Tolérance au risque : Dans un monde en bouleversement, leur capacité à agir sous pression et leur absence de peur face au risque sont cruciales.

      Pensée visuelle et conceptuelle : À l'ère de l'intelligence artificielle, leur aptitude à penser en images plutôt qu'en checklists est un avantage (ex: en cybersécurité).

      Créativité : Une capacité à apporter des perspectives divergentes, essentielles à l'intelligence globale d'une société.

      Conclusion :

      La gestion du TDAH appelle à un double mouvement.

      D'une part, une prise en charge médicale rigoureuse pour ceux qui souffrent de leur fonctionnement cérébral.

      D'autre part, une adaptation de l'environnement social et professionnel (flexibilité des procédures, tolérance à l'agitation) pour permettre à ces individus d'exprimer leur potentiel sans s'épuiser à vouloir rejoindre une norme rigide.

    1. Briefing : Génétique et Réussite Scolaire

      Synthèse de la problématique

      Ce document synthétise l'intervention de Franck Ramus concernant l'influence des facteurs génétiques sur la réussite scolaire.

      L'analyse repose sur deux postulats fondamentaux : les enfants arrivent à l'école avec des inégalités déjà constituées, et ces inégalités résultent d'une combinaison de facteurs environnementaux (sociaux, familiaux, prénataux) et génétiques.

      L'objectif est de déconstruire les réticences idéologiques face à la génétique comportementale en s'appuyant sur des données probantes issues de la recherche contemporaine.

      Points clés à retenir :

      Héritabilité : Environ 50 % des différences d'intelligence générale et 30 % des différences de réussite scolaire entre individus sont attribuables à des facteurs génétiques.

      Scores polygéniques : Ces nouveaux outils de mesure expliquent entre 11 % et 13 % de la variance du niveau d'études, un ordre de grandeur comparable à celui du revenu des parents ou du niveau d'éducation de la mère.

      Interaction gène-environnement : L'environnement fourni par les parents est lui-même partiellement influencé par leur propre patrimoine génétique (concept de "nurture génétique").

      Implications pédagogiques : La connaissance des bases génétiques ne justifie pas l'inaction, mais plaide pour une différenciation pédagogique accrue afin de traiter l'hétérogénéité réelle des élèves.

      --------------------------------------------------------------------------------

      I. Déconstruction des obstacles idéologiques et conceptuels

      Le débat sur la génétique est souvent entravé par des peurs irrationnelles que la recherche scientifique s'efforce de lever :

      1. Le Réductionnisme : Contrairement aux critiques, les biologistes n'ambitionnent pas de réduire l'humain à ses gènes.

      Ils prônent une compréhension multi-niveaux (moléculaire, cellulaire, neuronal, psychologique et sociologique).

      2. Le Déterminisme : Les gènes ne sont pas un destin "gravé dans le marbre".

      Les influences environnementales sont tout aussi déterminantes que les influences génétiques ; la science cherche simplement à identifier les causes, quelles qu'elles soient.

      3. Le Paralogisme Naturaliste : L'idée que ce qui est "naturel" (génétique) serait acceptable ou immuable est un biais de raisonnement.

      La société se construit souvent en réaction à la nature pour réduire les injustices.

      4. Le Paralogisme Moraliste : Nier un fait scientifique au motif que ses implications morales déplaisent revient à prendre ses désirs pour des réalités, ce qui nuit à l'élaboration de solutions efficaces.

      --------------------------------------------------------------------------------

      II. Modélisation de la réussite scolaire

      La réussite scolaire est déterminée par une structure complexe de facteurs interactifs :

      Facteurs de réussite

      | Catégorie | Éléments clés | | --- | --- | | Facteurs Externes | Enseignement, moyens financiers, opportunités, effort personnel. | | Capacités Cognitives | Langage, mémoire de travail, attention, raisonnement abstrait. L'intelligence générale (QI) est la moyenne pondérée de ces fonctions. | | Facteurs "Non-Cognitifs" | Motivation, personnalité (conscienciosité, ouverture), dispositions à l'effort. |

      Dynamique des boucles de rétroaction

      L'effort améliore les capacités cognitives (la scolarisation est le meilleur levier connu pour augmenter l'intelligence).

      La réussite renforce la motivation, créant un cercle vertueux.

      Le génome et l'environnement agissent en amont sur le développement de ces capacités et traits de personnalité.

      --------------------------------------------------------------------------------

      III. Preuves scientifiques de l'influence génétique

      La science mobilise trois types de preuves convergentes pour établir le rôle de la génétique :

      1. Études d'apparentés (Jumeaux et adoptions)

      Adoption : Sur le long terme, les scores de QI des enfants adoptés sont plus corrélés à ceux de leurs parents biologiques qu'à ceux de leurs parents adoptifs (corrélation tendant vers zéro avec les parents adoptifs à l'âge adulte).

      Jumeaux : Les jumeaux monozygotes (100 % de gènes communs) se ressemblent beaucoup plus que les jumeaux dizygotes (50 % de gènes communs) pour l'intelligence et la réussite scolaire.

      Conclusion : L'héritabilité de l'intelligence générale est estimée à environ 50 %.

      2. Études des mutations génétiques

      • Plus de 1 000 gènes ont été identifiés comme ayant un impact sur l'intelligence en cas de mutation (ex: trisomie 21, gène FoxP2 pour le langage, gènes associés à la dyslexie).

      Le continuum de sévérité : Il n'y a pas de rupture nette entre le pathologique et le normal.

      Les mutations peuvent être fortes (suppression d'une protéine) ou faibles (altération de la quantité d'expression), produisant un impact graduel sur les capacités cognitives.

      3. Études génomiques (GCTA et Scores Polygéniques)

      Méthode GCTA : Mesure directe de la similarité génétique sur l'ADN. Elle confirme une héritabilité de 30 à 35 % pour l'intelligence et les matières scolaires (lecture, maths, sciences).

      Scores Polygéniques (PGS) : Compilation de milliers de petites variations génétiques. Le score "EA3" explique 11 à 13 % de la variance du niveau d'études.

      Exemple : Un individu dans le quintile supérieur de score génétique a 50 % de chances d'obtenir un diplôme du supérieur, contre 10 % pour le quintile inférieur.

      --------------------------------------------------------------------------------

      IV. Complexité : L'interdépendance Gènes-Environnement

      L'analyse démontre que gènes et environnement ne sont pas des entités isolées mais profondément imbriquées.

      La confusion Gène-Environnement ("Genetic Nurture")

      Les caractéristiques environnementales (nombre de livres à la maison, revenus) sont en partie héritables.

      • Les gènes des parents influencent leurs propres capacités cognitives et leur statut socio-économique.

      • Ce statut détermine l'environnement qu'ils créent pour l'enfant.

      Résultat : Environ 50 % de la corrélation entre le milieu social et la réussite de l'enfant passe par la transmission génétique, et non par une influence environnementale pure.

      Effet additif

      Les facteurs sont cumulatifs :

      Injustice maximale : Faible score génétique + milieu familial défavorisé (< 10 % de réussite).

      Privilège maximal : Fort score génétique + milieu riche (60 % de réussite).

      --------------------------------------------------------------------------------

      V. Limites et applications pratiques

      Faible valeur prédictive individuelle

      Malgré leur intérêt statistique en recherche, les scores polygéniques ne permettent pas de prédire le destin d'un individu spécifique avec précision.

      La marge d'erreur est trop colossale pour justifier des décisions d'orientation ou de sélection (ex: sélection d'embryons).

      Le niveau scolaire réel à un instant T reste un bien meilleur prédicteur que le génome.

      Message aux acteurs de l'éducation

      Pour les enseignants, les causes (génétiques ou sociales) importent peu dans l'action immédiate car ils n'ont aucun levier sur le passé de l'enfant.

      Recommandations :

      1. Cibler le présent : Intervenir directement sur les manques cognitifs observés (ex: vocabulaire), quelle qu'en soit l'origine.

      2. Pratiquer la différenciation : Puisque les enfants sont inégaux, les traiter de manière égale (uniforme) accroît les inégalités.

      3. Équité vs Égalité : Adopter une pédagogie inégale (aider davantage ceux qui en ont besoin) pour compenser les différences de prédispositions.

      Conclusion : La connaissance génétique ne doit pas être vue comme une menace mais comme un levier pour améliorer les recherches en sciences sociales et affiner les politiques éducatives en tenant compte de la réalité biologique de l'hétérogénéité humaine.

    1. Berners-Lee is building tools that aim to resist the Big Tech platforms, give users control over their own data, andprevent A.I. from hollowing out the open web. Illustration by Tim Bouckley

      [https://media.newyorker.com/photos/68d41dd5a787e07278d41d3f/master/w_960,c_limit/r47425.jpg

      This image visually represents Berners-Lee as surrounded by browser windows, symbolizing how his invention became the foundation of the modern digital world. The web has expanded far beyond its original academic purpose and now shapes communication, commerce, and everyday life. It also suggests the overwhelming scale of the web today compared to its original vision.

    2. Hypertext datedto the nineteen-forties, when the science administrator Vannevar Bush wrote anarticle about a device that could represent knowledge “As Freely as We MayThink.”

      Hypertext is the core concept behind the web. It allows documents to link to each other instead of existing in isolation. Vannevar Bush’s Memex concept influenced Berners-Lee’s creation of HTML. This shows that the web was built on earlier ideas about organizing knowledge in a connected and accessible way.

    3. They bought out rivalsand turned into monopolies: between 2007 and 2018, Wu notes, Facebook,Microsoft, Google, and Amazon collectively acquired more than a thousand firms.

      This shows how the web shifted from an open system to one controlled by large corporations. Originally, anyone could create a website and participate equally. Now, platforms like Google, Facebook, and Amazon control access to information and user data. This represents a major transformation from the decentralized vision Berners-Lee originally intended.

    4. Another competitor was Gopher, developed at theUniversity of Minnesota.

      Gopher was an alternative system that organized information using hierarchical menus instead of hyperlinks. If Gopher had become dominant, the web might have looked more like a rigid file system instead of the flexible, interconnected structure we use today. HTML’s hyperlink model allowed information to be connected in a decentralized way, which made it more scalable and creative.

    5. began laying the web’s foundations: HTML, the language of web pages; HTTP,the protocol that governed their transmission; and URLs, the addresses thatlinked them together.

      This is one of the most important moments in the history of computing. HTML was created so documents could be structured in a way that computers and humans could both understand. Instead of files being isolated on individual machines, HTML allowed them to be linked together into a global network. Without HTML, the web would likely have remained fragmented, similar to early systems like CompuServe or AOL. HTML made the web universal and accessible.

    1. gone viral as part of posts supporting far-right and anti-immigrant groups.
      • description: image depicts a mass protest of british patriots waving the union jack flag
      • context: viral image shared in support of far right and anti immigration groups.
      • Image has been debunked as AI generated: objects in the foreground (flags, faces and limbs) bleed together.
    1. They have to get through many posts during their time, and given the nature of the content (e.g., hateful content, CSAM, videos of murder, etc.), this can be traumatizing for the moderators:

      This brings to my mind the historical example of the Mechanical Turk, and the current amazon based processes of the same name. Because the internet allows a level of abstraction from the labor which its existence necessitates, there is a lot of violence wreaked on the working classes that is never seen or discussed. I wonder if there is a way of providing compensation for the violence of these images in the jobs of the moderators.

      example of flat character functions

    2. Keep in mind that archetype simply means original pattern and does not always apply to characters. It can come in the form of an object, a narrative, etc.

      Archetypes do not strictly apply to characters

    3. protagonist is the focal point of the conflict, meaning that he or she is the main character of the story.

      Protagonist definition

    4. We use the term characterisation to describe the strategies that an author uses to present and develop the characters in a narrative.

      I have never heard of the word charecterisation before and now I understand the meaning

    1. How AI Is Changing The Role Of Teachers In Education

      Question 3- Blake Morgan’s article, How AI Is Changing the Role of Teachers in Education, argues that artificial intelligence is transforming teaching by automating administrative tasks and enhancing personalized learning. Morgan emphasizes that AI can free teachers from routine grading and paperwork, allowing them to focus on more meaningful interactions with students. Morgan highlights that AI enables more individualized learning experiences, as teachers can use data-driven insights to adjust lessons to each student’s needs. Morgan also points out that AI requires teachers to develop new skills, including digital literacy and the ability to guide ethical AI use in the classroom. Overall, Morgan advocates that the purpose of the article is to show how AI can empower teachers and improve student learning outcomes while acknowledging the need for careful integration.

    2. How AI Is Changing The Role Of Teachers In Education

      Question 2- I liked Blake Morgan’s article better because it provides practical examples of how AI tools are directly reshaping teachers’ responsibilities in classrooms.

    1. useful angles expressed in both degrees and radians is

      Unfortunately, the radians column is messed up, too tiny. $$30^{\circ}\longleftrightarrow\frac{\pi}{6}$$ $$45^{\circ}\longleftrightarrow\frac{\pi}{4}$$ $$60^{\circ}\longleftrightarrow\frac{\pi}{3}$$ $$90^{\circ}\longleftrightarrow\frac{\pi}{2}$$ $$120^{\circ}\longleftrightarrow\frac{2\pi}{3}$$ $$135^{\circ}\longleftrightarrow\frac{3\pi}{4}$$

    1. What content is considered “quality” content will vary by site, with 4chan considering a lot of offensive and trolling content to be “quality” but still banning spam (because it would make the site repetitive in a boring way), while most sites would ban some offensive content.

      This gets at the ethical consideration of how the internet ought to be split up, and if there should be an overall governing body to the internet. There's a thread of thought in internet ethics that purports the internet as a location which allows free speech for all, but we've seen that allowing sites like 4chan and in some cases reddit has demonstrated real harm and resulted in real violence. The issue reminds me of the tolerance paradox.

    1. Scrolling through other people's highlight reels can make your own life feel underwhelming by comparison. like everyone else is doing more, living more, looking better. That constant over-comparison can build into real anxiety and a sense that you're falling behind somehow.

    1. Learning about things like doomscrolling, trauma dumping, Munchausen by Internet, and digital self-harm was genuinely eye-opening. These point to something deeper about how these platforms affect people psychologically in ways that aren't always obvious.

    1. Individual users are often given a set of moderation tools they can use themselves, such as: Block an account: a user can block an account from interacting with them or seeing their content Mute an account: a user can allow an account to try interacting with them, but the user will never see what that account did. Mute a phrase or topic: some platforms let users block content by phrases or topics (e.g., they are tired of hearing about cryptocurrencies, or they don’t want spoilers for the latest TV show). Delete: Some social media platforms let users delete content that was directed at them (e.g., replies to their post, posts on their wall, etc.) Report: Most social media sites allow users to report or flag content as needing moderation. And there are other options and nuances as w

      With these moderations, social media has become safer. I do not block people, but when they offend me or do something bad, I'll block them. I'm glad that nowadays we have social media moderation because it prevents people from getting their feelings hurt. When people feel safer and more comfortable, they are more likely to continue using the platform. This shows why companies are incentivized to provide moderation tools; it protects users and helps retain them.

    1. Having a system with no moderators puts all the responsibility on the person running the site, which sounds like freedom until you realize what that actually means. You control everything, but you're also accountable for everything. Spam, illegal content, anything that ends up there is on you. That's manageable when a site is small, but as it grows and gets more attention, it becomes a real problem fast.

    1. Women are genuinely trapped at the intersection of capitalism and patriarchy

      Money systems and society’s rules about women work together to make women feel like they always need to improve how they look and act

    2. pop culture has started to reflect the fractures in selfhood that social media creates.

      Constant comparison creates anxiety because people compete with perfected photos.

    3. They encourage you to produce yourself as the body that they ide- ally display.”

      Tolentino explains that fashion and advertising don’t just show beauty standards, they make people change themselves to match those standards.

    4. life has become frictionless.”

      Tolentino shows how capitalism, feminism, and consumer culture combine to turn self improvement into a lifelong responsibility.

    5. In 1844, “optimize” was used as a verb for the first time, mean- ing “to act like an optimist.”

      Tolentino shows optimization started as an economic idea but slowly spread into everyday life thinking.

    6. The beauty ideal asks you to understand your physical body as a source of potential and control.

      Self improvement feels empowering but creates a lot of pressure still

    7. ven in situations like this, in which women’s choices are constrained and dictated both by social expectations and by the arbitrary dividends of beauty _work, which is more rewarding if one is young and rich and con- ventionally attractive to begin with.

      She critiques a version of feminism that treats all choices as empowerment, but those choices are shaped by society pressure

    8. he default assumption tends to be that it is politically important to designate everyone as beautiful, that it is a meaningful project to make sure that everyone can become, and feel, increasingly beau- tiful. We have hardly tried to imagine what it might look like if our culture could. do the opposite—de-escalate the situation, make beauty matter less.

      Tolentino is trying to say that instead of reducing beauty pressure, society tries to include everyone inside the beauty system but the problem never fully goes away

    9. Photoshop use in ads and on magazine covers, which on the one - hand instantly exposed the artificiality and dishonesty of the con- temporary beauty standard, and on the other showed enough of a. ' powerful, lingering desire for “real” beauty that it cleared space for ever-heightened expectations.

      Even movements like sever editing which is meant to fight unrealistic beauty can create new pressures which now causes people to think they must look naturally perfect all the time

    10. Under this ethical ideal, women attribute implicit moral value to the day-to-day efforts of improving their looks, and failing to ‘\meet the beauty standard is framed as “not a local or partial fail- ure, but a failure of the self.”

      Instead of blaming unrealistic standards, women blame themselves. The system shifts responsibility from society to the individual.

    11. I like trying to look good, but it’s hard to say how much you can genuinely, independently like what amounts to a mandate. In 1991, Naomi Wolf wrote, in The Beauty Myth, about the peculiar fact that beauty requirements have escalated as women’s subju- gation has decreased.

      Tolentino is saying women may think they freely choose to live up to beauty standards , but those choices are shaped by social pressure. Even as women gain independence, beauty expectations actually increase.

    12. here beauty has historically functioned as a symbol for female worth and morality

      Question: why does society treat appearance like a measure of character?

    13. Beauty constituted a sort of “third shift,” Wolf wrote—an extra obligation in every possible setting.

      Summary: omen already balance work and home responsibilities, but beauty expectations add more stress to the job. Maintaining appearance requires constant effort.

    14. this seems to me to be the thing, with barre, that people pay $40 a class for, the investment that always brings back returns.:

      People are literally pay money to become better at surviving stressful lifestyles

    15. Barre feels like exercise the way Sweetgreen feels like eating: both might better be categorized as mechanisms that help you adapt to arbitrary, prolonged agony.

      Summary: the author is trying to say exercise here isn’t about joy or health, it trains people to endure stressful modern life and makes you work way harder.

    16. But today, in an economy defined by precarity, more of what was merely stupid and adaptive has turned stupid and compulsory.

      Things that used to be optional like working constantly now feels required just to survive.

    17. mechanically effi- cient salad-feeding session, conducted in such a way that one need not take a break from emails—is the good life. It means progress, individuation. It’s what you do when you've gotten ahead a little bit, when you want to get ahead some more. The hamster-wheel aspect has been self-evident for a long time now.

      Summary: Tolentino is saying modern success looks like being busy and efficient all the time. People think productivity equals happiness even though it keeps them stuck working nonstop.

    18. Buchanan described the chopped salad as “the perfect mid-day nutritional replenishment for the mid-level modern knowledge worker”

      Question: what parts of life are we losing when everything becomes optimized for productivity?

    19. But the worse things get, the more a person is compelled to optimize.

      Question: are people improving themselves or just trying to survive unrealistic expectations?

    20. The chopped salad is engineered. . . to free one’s hand and eyes from the task of consuming nutrients, so that precious atten- tion can be directed toward a small screen, where it is more urgently needed, so it can consume data:

      Paraphrase: even eating is designed for efficiency so people can keep working or consuming media.

    21. most pleasures end up being traps, and every public-facing demand escalates in perpetu- ity.

      Things meant to feel fun (fitness, beauty, lifestyle trends) become pressure and work.

    22. Figuring out how to “get better” at being a woman is a ridiculous and often amoral project

      Paraphrase: Trying to perfectly perform womanhood is impossible and unfair.

    23. It is harder for us to suspect images produced by our peers, and nearly impossible to get us to suspect the images we produce of ourselves, for our own pleasure and benefi

      Does social media make comparison worse because the images feel more real?

    24. Everything about this woman has been preemptively controlled to the point that she can afford the im- pression of spontaneity and, more important, the sensation of it— having worked to rid her life of artificial obstacles, she often feels legitimately carefree.

      Tolentino is trying to say her life looks natural, but actually requires a lot of money and effort.

    25. The ideal woman, in other words, is always optimizing.

      Women are expected to constantly improve their appearance, lifestyle, and productivity which means they are never staying satisfied.

    1. There are cases where that makes sense for the government to be in control, to block illegal content, hate speech, or misinformation. But it can just as easily become a tool to silence people, suppress different points of view, and limit freedom of expression. And that's where it gets complicated.

    2. eddit is composed of many smaller discussion boards, called subreddits. These subreddits range from friendly to very toxic, with different moderators in charge of each subreddit. Reddit as a larger platform decided to ban and remove some of its most toxic and hateful subreddits, including r/c***town (note: I censored out a racial slur for Black people), and r/fatpeoplehate. In a study of what happened after this ban: Post-ban, hate speech by the same users was reduced by as much as 80-90 percent. […] “Members of banned communities left Reddit at significantly higher rates than control groups. […] Migration was common, both to similar subreddits (i.e. overtly racist ones) and tangentially related ones (r/The_Donald). […] However, within those communities, hate speech did not reliably increase, although there were slight bumps as the invaders encountered and tested new rules and moderators.

      An important thing to consider when imposing censorship upon a certain platform is the likelihood of certain groups/communities of just migrating to another platform with less censorship. Is banning these groups the most effective way to curb hate speech?

    1. # Another concern is for the safety of the users on the social media platform (or at least the users that the platform cares about). Users who don’t feel safe will leave the platform, so social media companies are incentivized to help their users feel safe. So this often means moderation to stop trolling and harassment.

      User safety is a major concern for social media platforms. When harassment, trolling, or unsafe political content spreads, users may feel uncomfortable and leave the platform. Because of this, companies have a right to moderate harmful content to maintain trust and keep users engaged.

    2. So this often means moderation to stop trolling and harassment.

      This brings to quesiton many site's option for anonymity towards users for any purpose. We find that most times people feel more comfortable when it comes to online posting because there are no immediate repercussions to their actions. Anonymity provides these users an extra protective layer towards their hurtful actions and can provide stronger hateful media platform uses.

    1. When social media companies like Facebook hire moderators, they often hire teams in countries where they can pay workers less

      Oftentimes bigger companies cut corners in order to maintain their maximum output and income. With being paid less, their working conditions are extremely severe and inhumane. These "max-moderators" lose their social and moral integrity in order to produce more.

    2. What support should content moderators have from social media companies and from governments?

      Moderation is a field that contains a lot of gray area — it is important to consider prioritizing what needs to be taken down first, and then determining what is even worth removing. Clearer legislation is the first step to making moderators’ lives easier.

    1. Student primary home language was a dichotomous vari-able. Parents were asked whether a language other than English was regularly spoken in the home during the fall and spring of kindergarten.

      So important to consider this factor

    2. Hypothesis 2: Consistent with prior work using the ante-cedent-opportunity-propensity framework (Byrnes, 2020; Lewis & Farkas, 2017), we further hypothesized that the study’s kindergarten explanatory factors, particu-larly the family’s socioeconomic resources and the stu-dent’s propensities for acquiring advanced levels of science or mathematics skills (e.g., prior achievement and executive functioning) would substantially or fully explain racial and ethnic disparities in advanced science and mathematics achievement in first, second, third, fourth, and fifth grade.MethodDatabase, Design, and Analytical SampleWe analyzed the public-use version of the nationally repre-sentative Early Childhood Longitudinal Study, Kindergarten Class of 2010-11 (ECLS-K:2011) dataset. The ECLS-K:2011 is a population-based cohort followed from the fall of kinder-garten to the spring of fifth grade. The U.S. Department of

      Makes sense. Regarding the methods, I think that a logitudinal study with more cohorts would be better, instead of following just one cohort.

    3. Figure 1 displays a conceptual model of the study’s antecedent-opportunity-propensity framework. Antecedent factors help to explain why some students experience greater learning opportunities includ-ing in their homes and schools

      Very informative and a good way to explain what factors may hinder learning

    4. The nationally repre-sentative NAEP program only begins academically assessing students in fourth grade. The available longitudinal studies analyzing samples of elementary students often report on achievement disparities

      Not a lot of time to assess and again, there are others factors that should be considered

    5. he contrasting rates for Black and Hispanic children were .05 and .02, respectively (Bell et al., 2019). These rates would be expected to increase to .06 and .03 (and so percentage increases of 20% and 50%, respectively) for Black and Hispanic children displaying the same mathematics achievement as White chil-dren (Bell et al., 2019).

      How is this data being used for good?

    1. Mills argued that a truly just society would need to include ALL subgroups in devising and agreeing to the imagined social contract, instead of some subgroups using their rights and freedoms as a way to impose extra moderation on the rights and freedoms of other groups.

      This statement highlights that who sets the rules determines "what should be restricted" and "who is more likely to be restricted." Applied to platforms, this means content moderation is not a neutral technology, but rather an extension of a "social contract": if the rule-makers primarily represent powerful groups, moderation may draw its boundaries in their own favor, making vulnerable groups more susceptible to collateral damage or silencing. Consider Rawls's "veil of ignorance": if you didn't know you would be a minority, immigrant, sexual minority, or political dissident in the future, you would be more inclined to design a more appealable, transparent, consistent, and protective moderation system for the vulnerable. Therefore, "abstract moderation" here becomes a political and justice issue: moderation is not just about controlling extreme content, but also about preventing moderation power from being used to perpetuate inequality.

    2. Moderation, or being moderate, is something that is valued in many ethical frameworks, not because it comes naturally to us, per se, but because it is an important part of how we form groups and come to trust each other for our shared survival and flourishing.

      The "moderation" here emphasizes maintaining a sustainable coexistence between extremes: neither allowing all expression (leading to harassment, intimidation, and the proliferation of misinformation) nor excessive suppression (suffocating public discussion and diversity). Social media "content moderation/traffic limiting/banning" essentially translates this abstract "moderation" into enforceable boundaries, aiming to maintain basic order and trust on the platform. The problem is that when platforms concretize "moderation," they often use simple rules (keywords, model confidence levels, uniform policies) to replace complex contexts, thus easily turning "balance" into "brutal division." Therefore, content moderation is related to the moderation of moral ethics: it is essentially a governance practice of the "golden middle way," only often not done delicately or fairly enough.

    3. What would be considered bad actions that need to be moderated? What would be the goals of doing content moderation? How might this look different than current content moderation systems?

      I think that misinformation should be moderated, harassment or bullying. I think these are big problems that might undermine the users experience, and creates safeguards for them to enjoy the social media platform as they wish. This is beneficial for all users to make rational decisions.

    1. Have you ever reported a post/comment for violating social media platform rules? Have you ever faced consequences for breaking social media rules (or for being accused of it)? In unmoderated online spaces who has the most power and ability to speak and be heard? Who has the least power and ability to speak and be heard?

      Yes, I have reported someone for impersonating someone I know. If you let them, people can impersonate others and do weird things with it, like scam people. I think that social media not tolerating this really curbs that kind of scamming. For hate speech, I have probably when I was younger, but nowadays I don't see it much. I think in unmoderated spaces, everyone can be heard therefore no one can be heard.

    1. eLife Assessment

      This important study investigates how structurally diverse cardenolide toxins in tropical milkweed, especially mixtures containing nitrogen- and sulfur-containing variants, influence monarch caterpillar feeding, growth, and toxin sequestration. The experiments suggest that chemical diversity within a single group of plant toxins can have combined effects on even highly specialized herbivores that differ from the effects of each toxin alone. However, as the mixture design does not fully separate true diversity effects from the influence of the N,S-cardenolides themselves and the ecological basis for the chosen natural ratios remains weakly justified. As a result, the broader conclusions remain incomplete and would require more fully justified concentration regimes, mixture treatments that exclude N,S-cardenolides, and tests on living plants and non-adapted herbivores to firmly support the proposed coevolutionary interpretation.

    2. Reviewer #1 (Public review):

      Summary:

      In the ecological interactions between wild plants and specialized herbivorous insects, structural innovation-based diversification of secondary metabolites often occurs. In this study, Agrawal et al. utilized two milkweed species (Asclepias curassavica and Asclepias incarnata) and the specialist Monarch butterfly (Danaus plexippus) as a model system to investigate the effects of two N,S-cardenolides-formed through structural diversification and innovation in A. curassavica-on the growth, feeding, and chemical sequestration of D. plexippus, compared to other conventional cardenolides. Additionally, the study examined how cardenolide diversification resulting from the formation of N,S-cardenolides influences the growth and sequestration of D. plexippus. On this basis, the research elucidates the ecophysiological impact of toxin diversity in wild plants on the detoxification and transport mechanisms of highly adapted herbivores.

      Strengths:

      The study is characterized by the use of milkweed plants and the specialist Monarch butterfly, which represent a well-established model in chemical ecology research. On one hand, these two organisms have undergone extensive co-evolutionary interactions; on the other hand, the butterfly has developed a remarkable capacity for toxin sequestration. The authors, building upon their substantial prior research in this field and earlier observations of structural evolutionary innovation in cardenolides in A. curassavica, proposed two novel ecological hypotheses. While experimentally validating these hypotheses, they introduced the intriguing concept of a "non-additive diversity effect" of trace plant secondary metabolites when mixed-contrasting with traditional synergistic perspectives-in their impact on herbivores.

      Weaknesses:

      The manuscript has two main weaknesses. First, as a study reliant on the control of compound concentrations, the authors did not provide sufficient or persuasive justification for their selection of the natural proportions (and concentrations) of cardenolides. The ratios of these compounds likely vary significantly across different environmental conditions, developmental stages, pre- and post-herbivory, and different plant tissues. The ecological relevance of the "natural proportions" emphasized by the authors remains questionable. Furthermore, the same compound may even exert different effects on herbivorous insects at different concentrations. The authors should address this issue in detail within the Introduction, Methods, or Discussion sections.

      Second, the study was conducted using leaf discs in an in vitro setting, which may not accurately reflect the responses of Monarch butterflies on living plants. This limitation undermines the foundation for the novel ecological theory proposed by the authors. If the observed phenomena could be validated using specifically engineered plant lines-such as those created through gene editing, knockdown, or overexpression of key enzymes involved in the synthesis of specific N,S-cardenolides-the findings would be substantially more compelling.

    3. Reviewer #2 (Public review):

      I have reviewed both the original and revised version of this manuscript and while no additional experiments were added, I find the interpretations and discussion of the limitations of the study have improved. This is appreciated.

      My original concern regarding the mixture treatments largely remains. Figure 4 nicely shows that the mixtures are more potent than the average of all single compounds. However, Fig S3 shows that the effects of mixtures are not significantly different from effects of at least one, single N,S compound (voruscharin or uscharin) across all measured growth/sequestration responses. Essentially, the effects of single N,S compounds is similar to mixtures (which also contain N,S compounds).

      While the current results are certainly interesting as presented, in my view the main takeaway of the manuscript would be more compelling if it could be demonstrated that it isn't simply the presence of N,S compounds in the mixtures driving the observations. For example, does a mixture of all compounds except voruscharin or uscharin still have stronger growth/sequestration effects compared to single non-N,S compounds?

      Reviewer #2 (Public review):

      This study examined the effects of several cardenolides, including N,S-ring containing variants, on sequestration and performance metrics in monarch larvae. The authors confirm that some cardenolides, which are toxic to non-adapted herbivores, are sequestered by monarchs and enhance performance. Interestingly, N,S-ring-containing cardenolides did not have the same effects and were poorly sequestered, with minimal recovery in frass, suggesting an alternate detoxification or metabolic strategy. These N,S-containing compounds are also known to be less potent defences against non-adapted herbivores. The authors further report that mixtures of cardenolides reduce herbivore performance and sequestration compared to single compounds, highlighting the important role of phytochemical diversity in shaping plant-herbivore interactions.

      Overall, this study is clearly written, well-conducted and has the potential to make a valuable contribution to the field. However, I have one major concern regarding the interpretations of the mixture results. From what I understand of the methods, all tested mixtures contain all five compounds. As such, it is not possible to determine whether reduced performance and sequestration result from the complete mixture or from the presence of a single compound, such as voruscharin for performance and uscharin for sequestration. For instance, if all compounds except voruscharin (or uscharin) were combined, would the same pattern emerge? I suspect not, since the effects of the individual N,S-containing compounds alone are generally similar to those of the full mixture (Figure S3). By taking the average of all single compounds, the individual effects of the N,S-containing ones are being inflated by the non-N,S-containing ones (in the main text, Figure 4). In the mix, of course, they are not being 'diluted', as they are always present. This interpretation is further supported by the fact that in the equimolar mix, the relative proportion of voruscharin decreases (from 50% in the 'real mix'), and the target measurements of performance and sequestration tend to increase in the equimolar mix compared to the real mix.

      Despite this issue, the discussion of mixtures in the context of plant defence against both adapted and non-adapted herbivores is fascinating and convincing. The rationale that mixtures may serve as a chemical tool-kit that targets different sets of herbivores is compelling. The non-N,S cardenolides are effective against non-adapted herbivores and the N,S-containing cardenolides are effective against adapted herbivores. However, the current experiments focus exclusively on an adapted species. It would be especially interesting to test whether such mixtures reduce overall herbivory when both adapted and non-adapted species are present.

      It remains possible that mixtures, even in the absence of voruscharin or uscharin, genuinely reduce sequestration or performance; however, this would need to be tested directly to address the abovementioned concern.

      Thanks for these insightful reviews and your summary assessment. We certainly agree that ours was a laboratory study with a single specialized insect, and both mixtures types had all five compounds (controlling for total toxin concentration). Thus, our conclusion that combined effects of naturally occurring toxins (within the cardenolide class) have non-additive effects for the specialized sequestering monarch are constrained by our experimental conditions. In our assay we used two mixture types, equimolar and “natural” proportions. We acknowledge that the natural proportions will vary with plant age, damage history, etc. of the host plant, Asclepias curassavica. Our proportions were based on growing the plants a few different times under variable conditions. Although we did not conduct these experiments on non-adapted insects, we discuss a related experiment that was conducted with wild-type and genetically engineered Drosophila (Lopez-Goldar et al. 2024, PNAS). In sum, we appreciate the reviewers’ comments.

      Recommendations for the authors:

      Reviewing Editor Comments:

      (i) More convincingly justify the choice and ecological relevance of the "natural" cardenolide ratios, (ii) Clarify the interpretation of mixture effects, and (iii) more explicitly discuss the limitations of leaf-disc assays and the absence of non-adapted herbivores in light of the broader coevolutionary claims.

      Thank you for these suggestions. We have added several sentences of text to the Discussion section to make these points.

      Reviewer #1 (Recommendations for the authors):

      (1) Statistical analysis is missing from Figure 3 and Figure S3, making it difficult to assess the significance of the data.

      Much of the data in Fig. 3 is meant for descriptive presentation, with the main statistical analysis (contrast between N,S and non-N,S cardenolides given in the main text of the results. We have added treatment differences between the sequestration efficiencies to the figure as well.

      (2) To help readers intuitively understand how certain results (such as ECD and sequestration efficiency) were calculated, the authors can provide the equations used for these computations.

      Thank you, this was given in the methods and we have added it to the Result on first mention as well.

      (3) For Figure 4, we suggest presenting the results of the equal mixture treatment and the realistic mixture treatment separately, rather than averaging the results from these two types of treatments.

      We understand and appreciate this comment – all of the treatment means are given in Fig. S3. For this particular figure we have opted to stick with the binary comparison (singles vs. mixed) to maximize replication for statistical tests (typically n = 25 vs. 10).

      Reviewer #2 (Recommendations for the authors):

      Given the interpretations and discussion generally, I feel the manuscript would benefit from either additional experiments (mixtures w/o N-S compounds), inclusion of non-adapted herbivore performance, or reframing of the explicit interpretations from your findings.

      We have added some caveats to the text but not added any additional experiments.

      Also, for all treatments/mixtures are concentrations above the IC50? Perhaps this could be calculated from the information presented, but it may be best to explicitly mention this.

      This is an interesting question. IC50’s are estimated from in vitro assays (with the enzyme and toxins in microplate wells) and so are not translatable to foliar concentrations. As indicated in the text, we chose cardenolide levels based on foliar concentrations to match A. curassavica.

      Some minor points:

      (1) Although the intact N,S-ring-containing compounds are recovered in low amounts in frass (and not sequestered), is there evidence of N,S-ring components being otherwise traceable in the frass? For example, can excess S or N be detected in frass? This could provide insight into differential detoxification or reincorporation of these elements, potentially explaining variation between voruscharin and uscharin.

      Great question! We have not been able to detect breakdown projects. In other experiments we have conducted mass spectrometric analysis of bodies and frass, but have not been able to find the features representing breakdown products. Nonetheless, as mentioned below, the main conversion products are evident and measurable, as in this study.

      (2) As a point of curiosity, is there evidence of interconversion between such compounds? For instance, if monarchs are fed only voruscharin, can other cardenolides be detected in their tissues?

      Yes, we have tried to make this more clear in the text. Both uscharin and voruscharin are converted to calotropin and calactin.
