    1. A practical example of service design thinking can be found at the Myyrmanni shopping mall in Vantaa, Finland. The management attempted to improve the customer flow to the second floor as there were queues at the landscape lifts and the KONE steel car lifts were ignored. To improve customer flow to the second floor of the mall (2010) Kone Lifts implemented their 'People Flow' Service Design Thinking by turning the Elevators into a Hall of Fame for the 'Incredibles' comic strip characters. Making their Elevators more attractive to the public solved the people flow problem. This case of service design thinking by Kone Elevator Company is used in literature as an example of extending products into services.

      $$ \begin{aligned} Q(t) & \equiv Q_{\nabla\phi}(\Sigma) := {1 \over 4\pi} \int_{\Sigma} \langle \nabla\phi, \nu \rangle d\sigma_g \\ %% & = {1 \over 4\pi} \int_{\Sigma} d\phi \cdot \nu d\sigma = {1 \over 4\pi} \int_{\Sigma} \frac{\partial\phi}{\partial\nu} d\sigma \end{aligned} $$

      $$ \begin{aligned} \Longrightarrow \frac{dQ}{dt} = {1 \over 4\pi} \int_{\Sigma} \left[ d(\partial_t \phi) \cdot \nu + d\phi \cdot \partial_t \nu + d\phi \cdot \nu \frac{tr_{\Sigma} \partial_t g}{2} \right] d\sigma \end{aligned} $$

      Tomando \( \alpha = 2 \), obtemos: $$ \begin{aligned}

      • {tr_{\Sigma} \partialt g \over 2} & = R - Rc(\nu, \nu) - \alpha \left( |\nabla \phi|^2 - (\partial{\nu} \phi)^2 \right) \ & = R - Rc(\nu, \nu) - 2 \left( |\nabla \phi|^2 - (\partial_{\nu} \phi)^2 \right) \end{aligned} $$

      que é justamente a função que precisamos estimar (veja prova do corolário 5.2), no caso particular de um campo gradiente.

      Haja visto que no na aproximação eletrostática do eletromagnetismo clássico, o campo elétrico (em domínios simplesmente conexos) é gerado por um potencial escalar, isso sugere que, pelo menos nessa aproximação particular, podemos utilizar esse fluxo \((RH)_{\alpha}\), tomando o pontical elétrico como dado inicial para o fluxo do calor para mapas harmônicos.

      Essa ideia é inspirada nas ideias das seções 2 e 3, desse artigo do Benhard List, onde ele observa que soluções estáticas desse fluxo, com \(\alpha\) escolhido adequadamente, coincide com as soluções estáticas para a equação de Einstein no vácuo.

    1. In other words, when YouTube fine-tunes its algorithms, is it trying to end compulsive viewing, or is it merely trying to make people compulsively watch nicer things?

      YouTube's business interests are clearly rewarded by compulsive viewing. If it is even possible to distinguish "nicer" things, YouTube might have to go against its business interests if less-nice things DO lead to more compulsive viewing. Go even deeper, as Rob suggests below, and ask if viewing itself can shape both how (compulsive?) and what (nice or not-nice?) we view?

    1. But I actually think stock and flow is a useful metaphor for media in the 21st century. Here’s what I mean: Flow is the feed. It’s the posts and the tweets. It’s the stream of daily and sub-daily updates that reminds people you exist. Stock is the durable stuff. It’s the content you produce that’s as interesting in two months (or two years) as it is today. It’s what people discover via search. It’s what spreads slowly but surely, building fans over time.

    1. Flaherty’s data and theory indicate that rather than the amount and nature of the objective experiences in a situation, what makes time seem to pass extra slowly or quickly is the extent to which the individual engages in conscious infor­mation processing during the time. When the amount of conscious information processing is about average for the individual, the individual experiences time as passing at what that individual has come to perceive as the usual rate, but when the amount of such processing is high, time appears to slow down (pro­tracted duration); when such information processing is low, time appears to speed up (temporal compression)

      The experience of time passing (fast or slow) is related to conscious information processing.

    1. Because time is not physical, the human perception of time is subjective: the passage of time can seem slower or faster depending on factors liketask

      gets at the experience of "flow" (See Csikszentmihalyi)

    1. Furthermore, and differentiating digital time from clock time, he suggests that a lack of adherence to chronological time is compounded by the fact that digital technologies connect with a flow of information that is al-ways and instantly available. He argues that continual change, which is bound up with web services such as social network sites, blogs and the news, is central to the experi-enced need for constant connectivity.

      Q: How does this idea of time vs information flow affect the data harvested during a digital crowdwork process in humanitarian emergencies?

      Q: How does this idea of time vs information flow manifest when the information flow is not chronological due to content throttling or algorithmic decisions on what content to deliver to a user?

    1. Her astonishing quickness of perception, detected a change in my voice, or my manner, when I put that question, which warned her that I had been speaking all along with some ulterior object in view. She stopped, and taking her arm out of mine, looked me searchingly in the face.

      At the end of the first narrative, Rachel break the engagement and Godfrey agree with it without argument. The reason why Rachel breaks the engagement and the reason why Godfrey accepts it happily is revealed by Mr. Bruff in this chapter. I think it is a typical example of the unique information flow in Moonstone. The writer is so sagacious that he arranges one narrator to show the strange events and lets another narrator reveal the truth and raise some new puzzles. As a result, the writer can promote the development of the plot and reveal the mystery behind it at the same time. It makes readers keep curious all the time because there is fascinating''truth'' in every narrative.

      The idea of making time more present/more felt is counter-intuitive to how time is experienced in crisis response as urgent, as a need for effiicency, as an intense flow (Csikszentmihalyi) that disappears.

    1. WHERE TO FIND FLOWFlow tends to occur when a person faces a clear set of goals that require appropriate responses. It is easy to enter flow in games such as chess, tennis, or poker, because they have goals and rules that make it possible for the player to act without questioning what should be done, and how. For the duration of the game the player lives in a self-contained universe where everything is black and white. The same clarity of goals is present if you perform a religious ritual, play a musical piece, weave a rug, write a computer program, climb a mountain, or perform surgery. In contrast to normal life, these "flow activities" allow a person to focus on goals that are clear and compatible, and provide immediate feedback.article continues after advertisementgoogletag.cmd.push(function() { googletag.display('div-gpt-ad-1404853927369-9'); });Flow also happens when a person's skills are fully involved in overcoming a challenge that is just about manageable, so it acts as a magnet for learning new skills and increasing challenges. If challenges are too low, one gets back to flow by increasing them. If challenges are too great, one can return to the flow state by learning new skills.How often do people experience flow? If you ask a sample of typical Americans, "Do you ever get involved in something so deeply that nothing else seems to matter and you lose track of time?" roughly one in five will say that this happens to them as much as several times a day, whereas about 15 percent will say that this never happens to them. These frequencies seem to he quite stable and universal. For instance, in a recent survey of 6,469 Germans, the same question was answered in the following way: Often, 23 percent; Sometimes, 40 percent; Rarely, 25 percent; Never or Don't Know, 12 percent.A more precise way to study flow is the Experience Sampling Method, or ESM, which I developed at the University of Chicago in the early 1970s. This method provides a virtual filmstrip of a person's daily activities and experiences. At the signal of a pager or watch, which goes off at random times within each two-hour segment of the day, a person writes down in a booklet where she is, what she is doing, what she is thinking about, and whom she is with, then she rates her state of consciousness on various numerical scales. At our Chicago laboratory, we have collected over the years a total of 70,000 pages from about 2,300 respondents. Investigators in other parts of the world have more than tripled these figures.article continues after advertisementgoogletag.cmd.push(function() { googletag.display('div-gpt-ad-1456244145486-0'); });The ESM has found that flow generally occurs when a person is doing his or her favorite activity--gardening, listening to music, bowling, cooking a good meal. It also occurs when driving, talking to friends, and surprisingly often at work. Very rarely do people report flow in passive leisure activities, such as watching television or relaxing.Almost any activity can produce flow provided the relevant elements are present, so it is possible to improve the quality of life by making sure that the conditions of flow are a constant part of everyday life.FLOW AT WORKAlthough adults tend to be less happy than average while working, and their motivation is considerably below normal, ESM studies find more occasions of flow on the job than in free time. This finding is not that surprising: Work is much more like a game than most other things we do during the day. It usually has clear goals and rules of performance. It provides feedback either in the form of knowing that one has finished a job well done, in terms of measurable sales or through an evaluation by one's supervisor. A job tends to encourage concentration and prevent distractions, and ideally, its difficulties match the worker's skills.Nevertheless, if we had the chance most of us would like to work less. One reason is the historical disrepute of work, which each of us learn as we grow up.Yet we can't blame family, society, or history if our work is meaningless, dull, or stressful. Admittedly, there are few options when we realize that our job is useless or actually harmful. Perhaps the only choice is to quit as quickly as possible, even at the cost of severe financial hardship. In terms of the bottom line of one's life, it is always better to do something one feels good about than something that may make us materially comfortable but emotionally miserable. Such decisions are notoriously difficult and require great honesty with oneself.article continues after advertisementgoogletag.cmd.push(function() { googletag.display('div-gpt-ad-1468856734952-0'); });Short of making such a dramatic switch, there are many ways to make one's job produce flow. A supermarket clerk who pays genuine attention to customers, a physician concerned about the total well-being of patients, or a news reporter who considers truth at least as important as sensational interest when writing a story, can transform a routine job into one that makes a difference. Turning a dull jot into one that satisfies our need for novelty and achievement involves paying close attention to each step involved, and then asking: Is this step necessary? Can it be done better, faster, more efficiently? What additional steps could make my contribution more valuable? If, instead of spending a lot of effort trying to cut corners, one spent the same amount of attention trying to find ways to accomplish more on the job, one would enjoy working--more and probably be more successful. When approached without too many cultural prejudices and with a determination to make it personally meaningful, even the most mundane job can produce flow.The same type of approach is needed for solving the problem of stress at work. First, establish priorities among the demands that crowd into consciousness. Successful people often make lists or flowcharts of all the things they have to do, and quickly decide which tasks they can delegate or forget, and which ones they have to tackle personally, and in what order. The next step is to match one's skills with whatever challenges have been identified. There will be tasks we feel incompetent to deal with. Can you learn the skills required in time? Can you get help? Can the task be transformed, or broken into simpler parts? Usually the answer to one of these questions will provide a solution;that transforms a potentially stressful situation into a flow experience.

    1. In hypo-egoic states, people have minimal thoughts about themselves, their reputations, and how people perceive them. They are more focused on concrete present-moment situations and outcomes in which they are not ego-involved or personally invested. Hypo-egoic states can include flow, loss of self-consciousness, and transcendence.
    1. While the title of this report does not really imply anything to contradict the results of the testing of the theory, the content of the report itself leaves room for interpretation as to what these results mean and who it applies to. The main study referenced conducted by the University of Rome (Loffredo) does show that the participants who were given dark chocolate showed a higher acute result than those who were given milk chocolate, their study was made up of a small group of 20. It could also be pointed out that they did not establish a portion of their group who were tested without the ingestion of chocolate to establish a better baseline for their results. Participants endurance on a treadmill was used to measure the effects of the chocolate, but there is no indication of how or if the participants increase in ambulatory movement, or having “warmed up” with their baseline test day may have contributed to the improved results after the chocolate was administered. Another point to note is where the author mentions a previous report she submitted (Aubrey) covering the similarity of the results of the chocolate study to a study on the affects of meditation on the body. While the result may be considered similar, the way the results were achieved were very different. The wording in the studies referenced for the benefits of meditation reflect a psychological improvement as a means for a physical response, while the chocolate experiment was testing a chemical application for a physiological response. This article, although not wrong or misrepresenting the study, simplifies much of the work and applies it to the general public. The author does manage to address that the study is incomplete, as an afterthought and could easily be interpreted as having less weight than the argument for chocolate treatment by simply being under represented or under explained. Further investigation is definitely needed to understand the “how and why” of the affects of chocolate/polyphenols on our bodies before we can set any sort of prescription in place. The study would need to be much more comprehensive or added to others that test this same result on other demographics to determine if the affects can be replicated on everyone, or to narrow down if they only get this result with those who have PAD.

    1. ould be nice if the process of figuring out what causes what is as simple as the light-switch example, but even this example is not as simple as it seems

      I feel like this sentence could be phrased differently; when reading "figuring out what causes what", it does not seem to flow smoothly.

    1. The Triple Feedback Loop offers a compass by aligning the information flows in a framework for operating a network of disparate players with different goals who work together on an overarching goal.

    1. I find I procrastinate for a good hour before getting down to the actual business of writing. This can include doing laundry, checking email, and reading the paper, until the guilt becomes inescapable. But once I start, I fall into that state of flow and become unaware of time passing. I love that feeling.
    1. frost heave
      Before the understanding of frost heave, there was a widely held belief that rocks and stones could grow and multiply. Stones were believe to grow from small pebbles. These stones then rose to the surface of the ground. Another belief was that stones were the offspring of “mother-stones” or “breeding-stones.” Today, it is known that this motion of stones moving upwards toward the surface of the ground is due to frost heave. Frost heave occurs when water in soil or rock freezes and thaws in a cyclic process. This causes an upward movement of the surface of the ground due to the freezing of water underneath. Geologist Stephen Taber from the University of South Carolina proved through extensive research that “it was not expansion, but rather the formation of ice lenses by segregation of water from the soil as the ground freezes that is the principal cause of frost heave.” He also showed that liquids other than water can also cause frost heave. The direction of heave is governed by the growth of ice lenses. Ice lenses form perpendicular to the direction of heat flow, so it is not always the case that frost heave occurs in the path of least resistance (Manz, 2011).

    1. Here is no water but only rock

      This obsession with "rock" and "water" can be tied to images of nature and a state of constant flow to dry and cracked. If this section or book lacks water, then it lacks flow and a substance it needs for survival in a natural sense. Again, we are faced with imagery of death in a metaphor.

    1. I want you to consider that in everything we are doing, we are harmonizing and flowing with the divine energies—with the outpouring of the river of Life, right at Its source. This river of Life flows freely and totally through and as your conscious experience of Being. It is always doing this, whether or not you have placed yourself properly in that Place. This is important to understand, since it makes clear that the only thing we need to do in order to find the resolution to whatever situation we are faced with, is simply go to the Source as the Door.

      Again, it's all happening at once....... the simply choice to become conscious, to be a Conscious Being

    1. You must learn to flow. You must learn that you are not self-directed in the sense of being a puppet with no strings attached, three-dimensionally speaking. From this standpoint, you will always seem to be a puppet with strings attached, and you will not have hold of the controls. From the standpoint of being as Conscious Being, as Fourth-dimensional Man, the concept of strings and controls is irrelevant.
    1. Do not misunderstand me. To know Who You Are, What You Are, and that You Are Where It’s All Happening is, indeed, Divine Fulfillment of Purpose. It is to be One with God. It is to flow with the Divine Energies. It is to be One and in Harmony with the Great Works of Divine Intelligence. BUT, IT IS ABSOLUTELY NORMAL!

      It is incredible yet simply as it is....

    1. The fact remains that as you let go in those other areas, just as you are doing right now while talking with me, the fullness will flow and be recognized by you—the fullness of your Being, that is.

    1. Many of the themes of this week--optimism, focus, flow--converge on another mental habit that relates to happiness: goal setting. Research suggests that setting goals for ourselves, and progressing toward those goals, can foster well-being, perhaps because our happiness is intertwined with having a sense of meaning, hope, and purpose in life--a topic we touched on in Week 1. However, research also suggests that not all goals contribute equally to our happiness.
    2. Familiarity with one another’s communication style also helps them respond to each other quickly, and we know from Csikszentmihalyi’s research that immediate feedback is critical to flow.

      Programming specific example: waiting for compile times, etc., is a killer.

    3. They found that, more than any particular type of activity, achieving flow was determined by the mix of challenge and support teachers provide: Engagement was high when students were appropriately challenged by complex goals and high teacher expectations but also supported through positive interactions with their teacher.
    4. They found that students were most engaged in school while taking tests, doing individual work, and doing group work, and less so when listening to lectures or watching videos. In addition, the students were most engaged and reported being in a better mood when they felt that their activities were under their own control and relevant to their lives. The researchers conclude that teachers can encourage more flow in their classrooms through lessons that offer choice, are connected to students’ goals, and provide both challenges and opportunities for success that are appropriate to students’ level of skill.
    5. Real learning, says Shernoff, requires student engagement—of which flow is the deepest form possible—and that involves a combination of motivation, concentration, interest, and enjoyment derived from the process of learning itself—qualities that are essential to Csikzentmihalyi’s definition of flow.
    6. But one place where we might not find too much flow these days, sadly, is in American schools. For years, the learning conditions in classrooms have been practically antithetical to the conditions people need to achieve flow and all the benefits that come with it. Especially in the era of No Child Left Behind and high-stakes testing, schools have often favored regimentation over self-directed learning, making it harder for students to get deeply engaged with topics that interest them. Paradoxically, these trends might be undermining the kind of student achievement they were designed to promote, and could even be causing student burnout.
    7. Have you ever been so engaged in an activity that you lost all sense of time? Hours passed, but you didn't notice; you felt calm, focused, deeply satisfied, even meditative? Psychologists have a word for that mental state: flow.
    8. But what happens when a challenge ramps up and we don't have the skills to meet it? We're at risk of experiencing "frazzle," as Daniel Goleman explains in the next video.
    9. Many people surveyed in research by Csikszentmihalyi and others report that flow is an optimal state, when they truly feel like they're "in the zone." These findings resonate with Matt Killingsworth's research on mind-wandering and happiness, which we covered earlier.  In flow, we experience the opposite of the kind of distracted mind-wandering that Killingsworth links to unhappiness.
    1. the river, of course, is the flow of your own Being unfolding Itself as Itself, and constituting your conscious experience of Being.

      Flow would be 4d.

    2. Good. Although we are going to be conversing more continuously today and tomorrow than we have in the past, it need not involve any sense of urgency or rush. Let it flow at its own rate, and you float with the current. The river will get to its destination.

      Urgency and rush are of the 3d world of the thinking mind.

    1. Letting go of wanting to feel happy all the time also encourages less self-consciousness about happiness. This may be helpful because many peak, pleasant experiences, characterized by total absorption in an activity, a phenomenon known as “flow,” are marked by a lack of self-awareness.
