Geoengineering: The Most Important Technology Nobody's Heard Of - 0 views

  • As Leinen put it, even if the proposals on the table at Copenhagen had been adopted, we’d still end the century with an atmospheric carbon dioxide of 700 parts per million–more than enough to cause climate upheaval, raise seas dramatically, and so forth.

Did Culture, Not Biology, Develop Humanity's Sense of Fair Play? - 0 views

  • in a new study published in Science, scientists studying groups of people from different societies have suggested that our sense of fairness may depend on the type of society we live in.
  • Lead researcher Joseph Henrich observed that members of smaller groups were unwilling to punish selfish behavior and were willing to keep much of the money for themselves. This may be because smaller communities lack the social norms or informal institutions like markets and religion, causing them to have narrower concepts of fairness.
  • However critics argue that in the absence of cultural context, the tests seem weak. Terming the games an “artificial situation,” evolutionary game theorists Martin Nowak and David Rand pointed out that college students are “used to [such] concepts and hunter-gatherers aren’t. Who knows how they’re understanding the game?”

Study: Massive Lava Flows Allowed Dinosaurs to Conquer the Planet - 0 views

  • This week in the Proceedings of the National Academy of Sciences, paleontologists say they’ve studied the period about 200 million years ago when dinosaurs first came to power, and found that while catastrophic volcanic activity may not explain dinosaur extinction, it could have explained why dinosaurs’ competitors disappeared and the terrible lizards took over the planet.
  • The scientists examined how two different isotopes (or forms) of carbon fluctuated during these volcanic eruptions. They found that the “heavy” form of carbon was depleted relative to the “light” form. They say this reflects disturbances in the carbon cycle at this time, including a spike in atmospheric carbon dioxide (CO2) and aerosols (fine solid particles)

40 years later, failure is still not an option - 0 views

  • This week marks three related anniversaries. April 12, 1961: Yuri Gagarin becomes the first man in space. That was 49 years ago today. April 14, 1970: An oxygen tank disrupts on Apollo 13, causing a series of catastrophic malfunctions that nearly leads to the deaths of the three astronauts. That was 40 years ago this week. April 12, 1981: The first Space Shuttle, Columbia, launches into space. That was 29 years ago today.
  • In 1970 Apollo 13 became our nation’s "successful failure".
  • But I’m old enough to remember when NASA could do the impossible. That was practically their motto. Beating the Soviets was impossible. Landing on the Moon was impossible. Getting Apollo 13 back safely was impossible.

  • Don’t get me wrong; the Shuttle is a magnificent machine. But it’s also a symbol of a political disaster for NASA.
  • Now, there’s a lot to be said for low Earth orbit. It is a fantastic resource for science, and I strongly think we should be exploiting it even more.
  • The idea of going back to the Moon is one I very much strongly support, but I get the impression that the plan itself is not well-thought out by NASA. The engineering, sure, but not the political side of it. And it’s the politics that will always and forever be NASA’s burden.
  • NASA needs a clear vision, and it needs one that is sturdy enough to resist the changing gusts of political winds.

Enter the nano-spiders - independent walking robots made of DNA - 0 views

  • Two spiders are walking along a track – a seemingly ordinary scene, but these are no ordinary spiders. They are molecular robots and they, like the tracks they stride over, are fashioned from DNA. One of them has four legs and marches over its DNA landscape, turning and stopping with no controls from its human creators. The other has four legs and three arms – it walks along a miniature assembly line, picking up three pieces of cargo from loading machines (also made of DNA) and attaching them to itself. All of this is happening at the nanometre scale, far beyond what the naked eye can discern. Welcome to the exciting future of nanotechnology.

Rand and Empirical Responsibility 6 - 0 views

  • the unconscious mind figures out which decks are bad before this awareness reaches the conscious mind. These findings are consistent with a large body of experimental research (see Timothy Wilson's Strangers to Ourselves).
  • The phrase "programmed by chance" means something along the lines of: not sufficiently focused.

  • according to Objectivism, the ultimate choice is to focus or not.
  • Did Rand provide any evidence for this view? Nope. Nor did she explain why she believed it. Then what reason can any rational person have for believing it? None whatever.
  • The conscious not only processes knowledge, but makes decisions and organizes memory.
  • The relevant evidence (see the above mentioned Strangers to Ourselves) strongly suggests that the conscious mind neither is nor could be in control all the time.
  • Since most of one's "inner states" lie below the threshhold of consciousness, they cannot be introspected.

Newly-discovered galactic arm means the Milky Way is more warped than we thought - 0 views

  • Here's our current understanding of the Milky Way's geography. The central bar has a huge proportion of our galaxy's stars, and jutting off of it are the two main arms of the spiral, which are the Perseus Arm and the Scutum-Centaurus Arm. The other four arms are mostly just gas and relatively unimportant. Our solar system is close to the Perseus Arm, which extends about 300 degrees around galactic center.
  • The discovery of this new arm provides good evidence that the Scutum-Centaurus Arm is just as large and expansive as the Perseus Arm, suggesting we live in an almost perfectly symmetrical galaxy.
  •  
    "It was back in 1852 that College of New Jersey astronomer Stephen Alexander first suggested the galaxy has a spiral shape. Since then, we've identified at least six arms of that spiral, and in the 1990s we found evidence that there is a star-heavy central bar running through the galactic plane. It's not easy figuring all this out because our neighboring stars tend to obscure the ones further away, making it difficult to identify our galaxy's larger structures with precision."

  • The first category is “Scientific and Engineering Practices,” and includes such laudable concepts as ” Analyzing and interpreting data.”
  • The second category is “Crosscutting Concepts That Have Common Application Across Fields,” by which they mean things like “Scale, proportion, and quantity” or ” Stability and change.

  • Whether or not these concepts and the grander conceptual scheme actually turn out to be useful will depend much more on implementation than on this original formulation. The easy part is over, in other words. The four ideas above seem vague at first glance, but they are spelled out in detail in the full report, with many examples and very specific benchmarks.

Relax! You'll Be More Productive - NYTimes.com - 0 views

  • More and more of us find ourselves unable to juggle overwhelming demands and maintain a seemingly unsustainable pace.
  • Paradoxically, the best way to get more done may be to spend more time doing less. A new and growing body of multidisciplinary research shows that strategic renewal — including daytime workouts, short afternoon naps, longer sleep hours, more time away from the office and longer, more frequent vacations — boosts productivity, job performance and, of course, health.
  • Taking more time off is counterintuitive for most of us. The idea is also at odds with the prevailing work ethic in most companies, where downtime is typically viewed as time wasted. More than one-third of employees, for example, eat lunch at their desks on a regular basis. More than 50 percent assume they’ll work during their vacations.
  • ...10 more annotations...
  • In a study of nearly 400 employees, published last year, researchers found that sleeping too little — defined as less than six hours each night — was one of the best predictors of on-the-job burn-out. A recent Harvard study estimated that sleep deprivation costs American companies $63.2 billion a year in lost productivity.
  • Daytime naps have a similar effect on performance. When night shift air traffic controllers were given 40 minutes to nap — and slept an average of 19 minutes — they performed much better on tests that measured vigilance and reaction time.
  • Longer naps have an even more profound impact than shorter ones. Sara C. Mednick, a sleep researcher at the University of California, Riverside, found that a 60- to 90-minute nap improved memory test results as fully as did eight hours of sleep.
  • The importance of restoration is rooted in our physiology. Human beings aren’t designed to expend energy continuously. Rather, we’re meant to pulse between spending and recovering energy.
  • we sleep in cycles of roughly 90 minutes, moving from light to deep sleep and back out again. They named this pattern the Basic-Rest Activity Cycle or BRAC. A decade later, Professor Kleitman discovered that this cycle recapitulates itself during our waking lives.
  • The difference is that during the day we move from a state of alertness progressively into physiological fatigue approximately every 90 minutes.
  • Our bodies regularly tell us to take a break, but we often override these signals and instead stoke ourselves up with caffeine, sugar and our own emergency reserves — the stress hormones adrenaline, noradrenaline and cortisol.
  • Working in 90-minute intervals turns out to be a prescription for maximizing productivity. Professor K. Anders Ericsson and his colleagues at Florida State University have studied elite performers, including musicians, athletes, actors and chess players. In each of these fields, Dr. Ericsson found that the best performers typically practice in uninterrupted sessions that last no more than 90 minutes.
  • Along the way, I learned that it’s not how long, but how well, you renew that matters most in terms of performance. Even renewal requires practice. The more rapidly and deeply I learned to quiet my mind and relax my body, the more restored I felt afterward. For one of the breaks, I ran. This generated mental and emotional renewal, but also turned out to be a time in which some of my best ideas came to me, unbidden. Writing just four and half hours a day, I completed both books in less than six months and spent my afternoons on less demanding work.
  • Our basic idea is that the energy employees bring to their jobs is far more important in terms of the value of their work than is the number of hours they work. By managing energy more skillfully, it’s possible to get more done, in less time, more sustainably. In a decade, no one has ever chosen to leave the company. Our secret is simple — and generally applicable. When we’re renewing, we’re truly renewing, so when we’re working, we can really work.

Machiavelli's Virtue - 0 views

  • For the state must organize the lives of millions of strangers and protect their need to selfishly acquire material possessions. If everyone stole from everyone else there would be anarchy. So the state monopolizes the use of force, taking it away from criminals. The state appeals not to God, but to individual selfishness. Thus, it clears the path for progress.
    • anonymous
       
      I positively *love* these 'meta' discussions about the state. I also love the idea that right-wing StratFor subscribing nutjobs, normally excited to learn about American military power, also have to wade through hard thoughts about the nature of the state.
  • Thomas Hobbes conceived of the modern state in his Leviathan, published in 1651. Hobbes is known wrongly as a gloomy philosopher because of his emphasis on anarchy. Hobbes was actually a liberal optimist, who saw the state as the solution to anarchy, allowing people to procure possessions and build a community. Hobbes knew that in the path toward a better world, order first has to be established. Only later can humankind set about making such order non-tyrannical.
  • But what did Hobbes' philosophy ultimately build on? It built on the first of the moderns, the early 16th century Florentine Niccolo Machiavelli, whose masterpiece, The Prince, was written 500 years ago in 1513. Here is an anniversary as important as the 500th anniversary of Columbus discovering America, celebrated in 1992.
  • ...22 more annotations...
  • By taking politics away from the narrowing fatalism of the medieval Roman Catholic Church, Machiavelli created the very secular politics from which Hobbes could conceive of the idea of the state.
  • The Prince may be less a work of cynicism than an instructional guide to overcome fate -- the fatalism of the Roman Catholic Church at that time. Thus, Machiavelli, more than Michelangelo perhaps, was the true inventor of the Renaissance.
  • The founders of the American Republic, who conceived of a polity in which church and state were separate and in which government existed to lay the rules for individuals to compete freely in the struggle to acquire wealth, owed much to Machiavelli and Hobbes.
  • But it is with Machiavelli, more than with Hobbes, where the principles of Western modernity truly begin.
  • Harvard Professor Harvey C. Mansfield Jr. Mansfield knows that it is more important to tell hard truths than it is to be liked and to get good reviews.
  • For by setting the terms for political reality, Machiavelli helps lay the foundation for geopolitics.
  • necessity frees people from religious faith. People may pray to God and go to church or synagogue or the mosque, but they must also acquire food and possessions for the sake of their loved ones, and thus they must enter into competition with their fellow human beings
  • just as nations must enter into competition with other nations.
  • Self-interest informs compromise with other human beings, and thus a state governed by self-interest is likely to compromise with other states: whereas a person or state governed solely by religious or moral virtue will tend to delegitimize as immoral those with whom he or it disagrees -- and therein lies conflict.
  • Virtue, in other words, is fine. But outstanding virtue -- because it tempts sanctimoniousness -- is dangerous. It is ultimately with this maxim that we find philosophical justification for moderation in contemporary politics and statecraft.
  • Those who find such thinking dark or cynical may be under the illusion that politics can bring respite from primitive necessity. Machiavelli, as Mansfield explains, is doubtful of this.
  • Yes, politicians may announce their intention to strive for truth and justice, but their unspoken concerns and desires, even in a democracy -- especially in a democracy -- are really about satisfying the selfish needs of their constituents.
  • Face it, primitive necessity is a fixture of the human condition. And, therefore, the only way to reduce conflict and suffering is through anxious foresight: the ability to foresee danger and necessities ahead. Thus are intelligence agencies more likely to prevent atrocities than humanitarians.
    • anonymous
       
      Ouch... This hurts. Probably because, though my monkey mind keeps resisting, I suspect it is very true.
  • In politics, explains Machiavelli (through Mansfield), one who does good often cannot be good. One must even learn how to be bad, or at least devious, for the sake of the common good. This is not necessarily the end justifies the means, for Machiavelli is careful to stipulate that only the minimum amount of cruelty should be applied for the sake of the greatest amount of good.
  • Machiavelli is all about results. He believes that you define something in politics not by its inherent excellence, but by its outcome.
  • A leader may be honest, unselfish and moral, but if he starts a war that later proved unnecessary and killed many people, he lacks virtue -- despite being on a personal level very sympathetic.
  • Conversely, a leader may be cynical, selfish and excessively ambitious, but if he keeps his countrymen away from danger he can still be said to have virtue -- despite being personally unappealing.
  • Likeability has nothing to do with virtue, it turns out.
  • For politics -- and especially geopolitics -- is concerned, according to Machiavelli, with knowing about the world rather than knowing about heaven. Indeed, precisely because Machiavelli was concerned with men and not with God, he was a humanist.
  • Machiavelli has his limits. For example, he could not have foreseen 20th century totalitarianism that mirrored the self-righteousness of the medieval Church with which he was in conflict, but on a much larger scale.
  • Because the stakes are arguably higher now because of weapons of mass destruction, there is a danger of taking Machiavelli too far and using his philosophy to justify all sorts of risky subterfuges.
  • But there is a greater danger in simply dismissing his philosophy as unworthy of our so-called enlightened age. For our age is determined less by globalization than by the battle of space and power, both between states and between groups within states themselves -- as witnessed most recently by the ethnic and sectarian turmoil throughout the Greater Middle East. An American leader who is forced to grapple with such anarchy, even as he must take care to adopt the right tone with a militarily ascendant China and with an economically rising Latin America, could do worse than act "Machiavellian." And thanks to Professor Mansfield, we now know the true meaning of that adjective.
  •  
    "What is modernity? Is it skyscrapers, smart phones, wonder drugs, atomic bombs? You're not even close. Modernity, at least in the West, is the journey away from religious virtue toward secular self-interest. Religious virtue is fine for one's family and the world of private morality. But the state -- that defining political structure of modern times -- requires something colder, more chilling. "

Science-Based Medicine » It's a part of my paleo fantasy, it's a part of my p... - 0 views

  • If I had to pick one fallacy that rules above all among proponents of CAM/IM, it would have to be either the naturalistic fallacy (i.e., that if it’s natural—whatever that means—it must be better) or the fallacy of antiquity (i.e., that if it’s really old, it must be better).
  • Basically, it’s a rejection of modernity, and from it flow the interest in herbalism, various religious practices rebranded as treatments
  • there is a definite belief underlying much of CAM that technology and pharmaceuticals are automatically bad and that “natural” must be better.
  • ...33 more annotations...
  • it’s hard not to note that cancer and heart disease are primarily diseases of aging, and life expectancy was so much lower back in the day that a much smaller percentage of the population lived to advanced ages than is the case today.
  • Even so, an implicit assumption among many CAM advocates is that cardiovascular disease is largely a disease of modern lifestyle and diet and that, if modern humans could somehow mimic preindustrial or, according to some, even preagricultural, lifestyles, that cardiovascular disease could be avoided.
  • Over the last decade, Cordain has become the most prominent promoter of the so-called “Paleo diet,” having written The Paleo Diet: Lose Weight and Get Healthy by Eating the Foods You Were Designed to Eat and multiple other books advocating a paleolithic-mimetic diet as the cure for what ails modern humans.
  • But how does one determine what the prevalence of cardiovascular disease was in the ancient past?
  • there have been indications that the idea that ancient humans didn’t suffer from atherosclerosis is a comforting myth, the most recent of which is a study published a week ago online in The Lancet by Prof. Randall C. Thompson of Saint Luke’s Mid America Heart Institute and an international team of investigators entitled Atherosclerosis across 4000 years of human history: the Horus study of four ancient populations.
  • Basically, it was a study of 137 different mummies from four different geographic locations spanning 4,000 years.
  • So, although there was a fair amount of evidence from studies of Egyptian mummies that atherosclerosis was not uncommon, in Egypt it was mainly the wealthy and powerful who were mummified after their deaths. Conceivably, they could have lived a very different lifestyle and consumed a very different diet than the average Egyptian living around that time.
  • So the authors obtained whole-body CT scans of the 137 mummies, either pre-existing scans or scans prospectively done, and analyzed them for calcifications.
  • The mummies to be included in the study were chosen primarily based on two factors, being in a good state of preservation with identifiable vascular tissue, and being adults.
  • The authors obtained identifying information from an extensive search of museum and other databases by a team of archeologists and experts in mummy restoration, and sex was determined by either analysis of the genitals and reproductive organs when present and by pelvic morphology when they were not present.
  • Age was estimated by standard analysis of architectural changes in the clavicle, femur, and humerus.
  • Finally, multiple anthropological and archeological sources were used in an attempt to estimate likely risk factors for the mummies.
  • Figure 2 summarizes the findings nicely: There’s also this video featured in a Nature report on the study showing the reconstructed scan of one of the mummies with atherosclerotic plaques in the coronary arteries.
  • As expected, more atherosclerosis correlates with advanced age, and the amount of atherosclerosis in the young and middle-aged (although the times in which the people who became these mummies after death lived age 50 was old) was less.
  • Although the sample number was far too small to draw definitive conclusions (as is often the case in archeological research), the prevalence of atherosclerotic disease in these mummies did not appear to correlate with the cultures in which the mummies lived.
  • As is noted in Thompson’s article, ancient Egyptians and Peruvians were agricultural cultures with farms and domesticated animals, Ancestral Puebloans were forager-farmers, and the Unangans were hunter-gatherers without agriculture. Indeed, the Peruvians and Ancestral Puebloans predated the written word and were thus prehistoric cultures.
  • One notes that no one, including the authors of this study, is saying that lifestyle and diet are not important factors for the development of atherosclerotic heart disease.
  • What they are saying is that atherosclerosis appears to be associated with aging and that the claims that mimicking paleolithic diets (which, one notes, were definitely not vegan) are overblown. In other words, there is a certain inherent risk of atherosclerosis that is related to aging that is likely not possible to lower further
  • I actually think that the authors probably went too far with that last statement in that, while they might be correct that atherosclerosis is an inherent component of human aging, it is quite well established that this inherent component of aging can at least be worsened by sedentary lifestyle and probably certain diets.
  • One notes that, although the Paleo Diet is not, strictly speaking, always sold as CAM/IM, the ideas behind it are popular among CAM advocates, and the diet is frequently included as part of “integrative medicine,” for example, here at the University of Connecticut website, where it’s under integrative nutrition.
  • In particular, the appeal to ancient wisdom and ancient civilizations as yet untouched by the evil of modernity is the same sort of arguments that are made in favor of various CAM modalities ranging from herbalism to vegan diets rebranded as being somehow CAM to the appeal to “natural” cures.
  • Indeed, the fetish for the “natural” in CAM is such that even a treatment like Stanislaw Burzynski’s antineoplaston therapy is represented as “natural” when in fact, if it were ever shown to work against cancer, it would be chemotherapy and has toxicities greater than that of some of our current chemotherapy drugs.
  • The book is by Marlene Zuk and entitled Paleofantasy: What Evolution Really Tells Us About Sex, Diet, and How We Live. Zuk is an evolutionary biologist, and in particular she points out how the evolutionary arguments favored by advocates of the Paleo diet don’t stand up to scrutiny.
  • The interview begins with Zuk confronting Cordain at a conference on evolution and diseases of modern environments. At his lecture, Cordain pronounced several foods to be the cause of fatal conditions in people carrying certain genes.
  • These foods included, predictably, cultivated foods such as bread (made from grain), rice, and potatoes. Zuk couldn’t resist asking a question, namely why the inability to digest so many common foods would persist in the population, observing, “Surely it would have been selected out of the population.” Cordain’s response? That humans had not had time to adapt to these foods, to which Zuk retorted, “Plenty of time.” Apparently, in her book, Zuk produces numerous examples of evolution in humans occurring in a time frame of less than 10,000 years, including:
  • Blue eyes arose 6,000 to 10,000 years ago
  • Rapid selection for the CCR5-D gene variant that makes some people immune to HIV
  • Lactase persistence (production past the age of weening of the lactase enzyme that digests lactose in milk) probably dates back only around 7,500 to 10,000 years, around the time that cattle were domesticated
  • there is no one diet or climate that predominated among our Paleolithic ancestors:
  • Zuk detects an unspoken, barely formed assumption that humanity essentially stopped evolving in the Stone Age and that our bodies are “stuck” in a state that was perfectly adapted to survive in the paleolithic environment. Sometimes you hear that the intervention of “culture” has halted the process of natural selection. This, “Paleofantasy” points out, flies in the face of facts. Living things are always and continuously in the process of adapting to the changing conditions of their environment, and the emergence of lactase persistence indicates that culture (in this case, the practice of keeping livestock for meat and hides) simply becomes another one of those conditions.
  • For this reason, generalizations about the typical hunter-gatherer lifestyle are spurious; it doesn’t exist. With respect to what people ate (especially how much meat), the only safe assumption was “whatever they could get,” something that to this day varies greatly depending on where they live. Recently, researchers discovered evidence that people in Europe were grinding and cooking grain (a paleo-diet bugaboo) as far back as 30,000 years ago, even if they weren’t actually cultivating it. “A strong body of evidence,” Zuk writes, “points to many changes in our genome since humans spread across the planet and developed agriculture, making it difficult at best to point to a single way of eating to which we were, and remain, best suited.”
  • Oh, and, as Zuk tells us, paleolithic people got cancer, too.
  • we humans have long been known to abuse and despoil our environment, even back in those “paleo” days. Indeed, when I took a prehistoric archeology course, which was largely dedicated to the period of time of the hunter-gatherers, one thing I remember my professor pointing out, and that was that what he did was largely the study of prehistoric garbage and that humans have always produced a lot of it.

What Your Culture Really Says - 0 views

  • The monied, celebrated, nuevo-social, 1% poster children of startup life spread the mythology of their cushy jobs, 20% time, and self-empowerment as a thinly-veiled recruiting tactic in the war for talent against internet giants. The materialistic, viral nature of these campaigns have redefined how we think about culture, replacing meaningful critique with symbols of privilege. The word “culture” has become a signifier of superficial company assets rather than an ongoing practice of examination and self-reflection.
  • Culture is not about the furniture in your office. It is not about how much time you have to spend on feel-good projects. It is not about catered food, expensive social outings, internal chat tools, your ability to travel all over the world, or your never-ending self-congratulation.

  • What your culture might actually be saying is… We have implemented a loosely coordinated social policy to ensure homogeneity in our workforce. We are able to reject qualified, diverse candidates on the grounds that they “aren’t a culture fit” while not having to examine what that means - and it might mean that we’re all white, mostly male, mostly college-educated, mostly young/unmarried, mostly binge drinkers, mostly from a similar work background. We tend to hire within our employees’ friend and social groups. Because everyone we work with is a great culture fit, which is code for “able to fit in without friction,” we are all friends and have an unhealthy blur between social and work life. Because everyone is a “great culture fit,” we don’t have to acknowledge employee alienation and friction between individuals or groups. The desire to continue being a “culture fit” means it is harder for employees to raise meaningful critique and criticism of the culture itself.
  • What your culture might actually be saying is… We have a collective post-traumatic stress reaction to previous workplaces that had hostile, unnecessary, unproductive and authoritarian meetings. We tend to avoid projects and initiatives that require strict coordination across the company. We might have difficulty meeting the expectations of enterprise companies and do better selling to startups organized like us. We are heavily invested in being rebels against traditional corporate culture. Because we communicate largely asynchronously and through chat, it is easy to mentally dehumanize teammates and form silos around functional groups with different communications practices or business functions.
  • What your culture might actually be saying is… Our employees must be treated as spoiled, coddled children that cannot perform their own administrative functions. We have a team of primarily women supporting the eating, drinking, management and social functions of a primarily male workforce whose output is considered more valuable. We struggle to hire women in non-administrative positions and most gender diversity in our company is centralized in social and admin work. Because our office has more amenities than home life, our employees work much longer hours and we are able to extract more value from them for the same paycheck. The environment reinforces the cultural belief that work is a pleasant dream and can help us distract or bribe from deeper issues in the organization.
  • What your culture might actually be saying is… We have enough venture funding to pay people to work on non-core parts of the business. We are not under that much pressure to make money. The normal work of the business is not sufficiently rewarding so we bribe employees with pet projects. We’re not entirely sure what our business objectives and vision are, so we are trying to discover it by letting employee passions take root. We have a really hard time developing work that takes more than a few people to release. We have lots of unfinished but valuable projects that get left behind due to shifts in focus, lack of concentrated effort, and inability to organize sufficient resources to bring projects to completion.
  • What your culture might actually be saying is… Management decisions are siloed at the very top layers of management, kept so close to the chest they appear not to exist at all. The lack of visibility into investor demands, financial affairs, HR issues, etc. provides an abstraction layer between employees and real management, which we pretend doesn’t exist. We don’t have an explicit power structure, which makes it easier for the unspoken power dynamics in the company to play out without investigation or criticism.
  • What your culture might actually be saying is… We fool ourselves into thinking we have a better work/life balance when really people take even less vacation than they would when they had a vacation policy. Social pressure and addiction to work has replaced policy as a regulator of vacation time.
  • What your culture might actually be saying is… Features are the most important function of our business. We lack processes for surfacing and addressing technical debt. We have systemic infrastructure problems but they are not relevant because we are more focused on short-term adoption than long-term reliability. We prioritize fast visible progress, even if it is trivial, over longer and more meaningful projects. Productivity is measured more by lines of code than the value of that code. Pretty things are more important than useful things.
  • Talk to your company about culture. Talk to other companies about culture. Stop mistaking symbology and VC spoils for culture. Be honest with yourself, and with each other. Otherwise, your culture will kill you softly with its song, and you won’t even notice. But hey, you have a beer keg in the office.

East China Sea, a Treasure for Oil, Is Fraught With Danger - 0 views

  • China and Japan thirst after an estimated 60 million to 100 million barrels of oil under the 482,000-square-mile sea east of Shanghai. Add to that 1 trillion to 2 trillion cubic feet of natural gas reserves. Their economies, Asia's two largest, need fuel for manufacturing of just about everything in the world. Both are net importers today.
  • Political analysts say a one-sided move to drill for oil or gas in the surrounding sea comes with so much risk that nothing's going on. China and Japan have discovered plenty of other sources for economic development oil in the meantime. Even the South China Sea, claimed by six governments, has stabilized since summer, letting oil exploration gingerly move forward.
  • "While resources are at stake, no one can realistically expect to safely drill for oil or gas if there is a full-on territorial dispute that could get militarized, since oil and gas rigs are inherently indefensible," says Scott Harold, associate political scientist with the American think tank Rand Corp.

  • in 2008 China and Japan had signed a resource-sharing deal for a disputed oil field, called Chunxiao by Beijing and Shirakaba by Tokyo. Then, two years ago, Japan accused China of breaking its word by going ahead on its own.
  • Looking at who had sought oil or gas there previously - as far back as the 1980s -- points to who now might lose out under today's conditions.

U.S. Energy Information Administration (EIA) - 0 views

  • The East China Sea is a semi-closed sea bordered by the Yellow Sea to the north, the South China Sea and Taiwan to the South, Japan's Ryukyu and Kyushu islands to the East and the Chinese mainland to the West. Evidence pointing to potentially abundant oil and natural gas deposits has made the sea a source of contention between Japan and China, the two largest energy consumers in Asia.
  • The sea has a total area of approximately 482,000 square miles, consisting mostly of the continental shelf and the Xihu/Okinawa (Chinese name/Japanese name) trough, a back-arc basin formed about 300 miles southeast of Shanghai between the two countries. The disputed eight Daioyu/Senkaku (Chinese/Japanese name) islands lie to the northeast of Taiwan, with the largest of them two miles long and less than a mile wide. Though barren, the islands are important for strategic and political reasons, as ownership can be used to bolster claims to the surrounding sea and its resources under the United Nations Convention on the Law of the Sea. To date, China and Japan have not resolved their ownership dispute, preventing wide-scale exploration and development of East China Sea hydrocarbons.
  • The East China Sea basin, particularly the Xihu/Okinawa Trough, is a potentially rich source of natural gas that could help meet Chinese and Japanese domestic demand.
  • ...33 more annotations...
  • China recently became the second largest net oil importer in the world behind the United States and the world's largest global energy consumer. Gas imports have also risen in recent years, and China became a net natural gas importer for the first time in almost two decades in 2007.
  • Japan is the third largest net importer of crude oil behind the United States and China, as well as the world's largest importer of liquefied natural gas (LNG), owing to few domestic energy resources.
  • Therefore, both China and Japan are interested in extracting hydrocarbon resources from the East China Sea to help meet domestic demand.
  • Hydrocarbon reserves in the East China Sea are difficult to determine. The area is underexplored and the territorial disputes surrounding ownership of potentially rich oil and natural gas deposits have precluded further development.
  • The EIA estimates that the East China Sea has between 60 and 100 million barrels of oil (mmbbl) in proven and probable reserves.
  • China began exploration activities in the Each China Sea in the 1980's, discovering the Pinghu oil and gas field in 1983. Japan co-financed two oil and gas pipelines running from the Pinghu field to Shanghai and the Ningbo onshore terminal on the Chinese mainland through the Asian Development Bank and its own Japanese Bank of International Cooperation (JBIC).
  • More recently, both China and Japan have concentrated their oil and gas extraction efforts in the contested Xihu/Okinawa trough.
  • Only the Pinghu field, operational since 1998, has produced oil in significant quantities to date. Pinghu's production peaked at around 8,000 to 10,000 barrels per day (bbl/d) of oil and condensate in the late 1990's, and leveled off to around 400 bbl/d in recent years. In the medium-term, the East China Sea is not expected to become a significant supplier of oil.
  • EIA estimates that the East China Sea has between 1 and 2 trillion cubic feet (Tcf) in proven and probable natural gas reserves.
  • In 2012, an independent evaluation estimated probable reserves of 119 Bcf of natural gas in LS 36-1, a promising gas field north of Taiwan currently being developed as a joint venture between CNOOC and U.K. firm Primeline Petroleum Corp.
  • The uncontested Pinghu field began producing in 1998, reaching a peak of approximately 40 to 60 million cubic feet per day (Mmcf/d) in the mid-2000's and declining in recent years.
  • China began producing at the contested Tianwaitian/Kashi field in 2006, claiming it as part of its Exclusive Economic Zone.
  • The Chinese government prioritizes boosting the share of natural gas as part of total energy consumption to alleviate high pollution from the country's heavy coal use. To that end, Chinese authorities intend to ramp up production and increase East China Sea gas to flow into the Yangtze River delta region, which includes Shanghai and Hangzhou, two large cities with growing gas demand.
  • In the 1990's, several foreign companies drilled a series of dry holes in uncontested waters.
  • In 2003, Unocal and Royal Dutch Shell announced a joint venture (JV) with CNOOC and Sinopec to explore gas reserves in the Xihu/Okinawa trough. However, Unocal and Shell withdrew from exploration projects in late 2004, citing doubts over the commercial viability of developing energy resources in the disputed area.
  • The companies plan to build pipelines and a 42 Mmcf/d onshore processing terminal at Wenzhou to accept the future gas supplies from the LS 36-1 field.
  • China and Japan have two separate, but interlinked disputes: where to demarcate the sea boundary between each country and how to assign sovereignty over the Daioyu/Senkaku Islands.
  • Despite multiple rounds of high-level negotiations between China and Japan, the two countries have thus far been unable to resolve territorial issues related to the East China Sea.
  • Until these disputes are resolved, it is likely that the East China Sea will remain underexplored and its energy resources will not be fully developed.
    • anonymous
       
      "resolved" is quaint sounding.
  • The Daioyu/Senkaku Islands consist of five uninhabited islets and three barren rocks. Approximately 120 nautical miles southwest of Okinawa, the islands are situated on a continental shelf with the Xihu/Okinawa trough to the south separating them from the nearby Ryukyu Islands.
  • Japan assumed control of Taiwan and the Daioyu/Senkaku islands after the Sino-Japanese War in 1895. Upon Japan's defeat in World War II, Japan returned Taiwan to China, but made no specific mention of the disputed islands in any subsequent document.
  • For several decades after 1945, the United States administered the islands as part of the post-war occupation of Okinawa. The islands generated little attention during this time
  • Although China had not previously disputed Japanese claims, the PRC claimed the islands in May 1970 after Japan and Taiwan held talks on joint exploration of energy resources in the East China Sea.
  • When the United States and Japan signed the Okinawa Reversion Treaty returning the disputed islands to Japanese control as part of the Okinawa islands, both the PRC and Taiwan challenged the treaty.
  • China claims the disputed land based on historic use of the islands as navigational aids. In addition, the government links the territory to the 1895 Shimonoseki Peace Treaty that removed Japanese claims to Taiwan and Chinese lands after World War II.
  • Japan claims that it incorporated the islands as vacant territory (terra nullius) in 1895 and points to continuous administration of the islands since that time as part of the Nansei Shoto island group.
  • According to the Japanese, this makes ownership of the islands a separate issue from Taiwan and the Shimonoseki treaty. Japan cites the lack of Chinese demands on the area prior to 1970 as further validation for its claim.
    • anonymous
       
      Both claims seem (on the surface) prudent and plausible. The perfect recipe for conflict.
  • China and Japan apply two different approaches to demarcating the sea boundary
  • Japan defines its boundary as the UNCLOS Exclusive Economic Zone (EEZ) extending westward from its southern Kyushyu island and Ryukyu islands.
  • China defines its boundary using the UNCLOS principle of the natural extension of its continental shelf.
  • The overlapping claims amount to nearly 81,000 square miles, an area slightly less than the state of Kansas.
    • anonymous
       
      Seriously? We're describing this in terms of "it's as big as Kansas"? I wonder how many "Empire State Buildings" would fit in it.
  • Japan has proposed a median line (a line drawn equidistant between both countries uncontested EEZs) as a means to resolve the issue, but China rejected that proposal.
  • Under UNCLOS, Article 121 (3), "Rocks which cannot sustain human habitation or economic life of their own shall have no exclusive economic zone or continental shelf". The Japanese have claimed that the disputed islands generate an EEZ and continental shelf. China has not taken an official position on the status of the Daioyu/Senkakus as rocks or islands.

Magic trick transforms conservatives into liberals - 0 views

  • When US presidential candidate Mitt Romney said last year that he was not even going to try to reach 47% of the US electorate, and that he would focus on the 5–10% thought to be floating voters, he was articulating a commonly held opinion: that most voters are locked in to their ideological party loyalty.
  • But Lars Hall, a cognitive scientist at Lund University in Sweden, knew better. “His calculation, only zeroing in on 10% of voters, is a risky proposition,” he says.
  • When Hall and his colleagues tested the rigidity of people’s political attitudes and voting intentions during Sweden’s 2010 general election, they discovered that loyalty was malleable: nearly half of all voters were open to changing their minds. The team's work is published today in PLoS ONE1.
  • ...7 more annotations...
  • Hall’s group polled 162 voters
  • The person conducting the experiment secretly filled in an identical survey with the reverse of the voter's answers, and used sleight-of-hand to exchange the answer sheets, placing the voter in the opposite political camp (see video above).
  • No more than 22% of the manipulated answers were detected, and 92% of the study participants accepted the manipulated summary score as their own.
  • What is interesting about the latest study is that, on the basis of the manipulated score, 10% of the subjects switched their voting intentions, from right to left wing or vice versa. Another 19% changed from firm support of their preferred coalition to undecided. A further 18% had been undecided before the survey, indicating that as many as 47% of the electorate were open to changing their minds, in sharp contrast to the 10% of voters identified as undecided in Swedish polls at the time.
  • Eugene Borgida, a social and political psychologist at the University of Minnesota in Minneapolis, is not surprised that some people changed their minds in the experiment. “We know that when you ask someone to explain their views, it tends to temporarily destabilize those views,” he says.
  • But Borgida wonders how durable the results would be. “I suspect if left alone these people would drift back to their baseline affiliation.” The team, he says, “may be overstating the proportion of people who are malleable”.
  • And after the trick was explained to them, many were pleased to find themselves not so hidebound by ideology as to be unable to even contemplate another point of view. But they still were often relieved that they were not supporting the wrong party

BioShock Infinite: an intelligent, violent videogame? - Read - ABC Arts | Australian co... - 1 views

  • Infinite has the difficulty of an inherited legacy: people like to point to the first BioShock (2007) as an example of how videogames made in studios by hundreds of people and financed by corporations can be artistic. It was, in a way, a beacon of hope for those who dreamed that the sheer industrial scale at the peak of the videogames business could translate into something worth taking seriously.
  • BioShock Infinite is a videogame with ideas. Set in 1912, it’s in part inspired by The Devil In The White City, Erik Larson’s 2003 novelistic account of the 1893 Chicago World’s Fair.
  • The city is beautiful, and possibly unparalleled in terms of visual design in a videogame: along with the expected white American neo-classical architecture, we get an astounding array of poster art and fashion, taking in both the decline of the strong silhouettes and Gibson Girl aesthetics of the 1910s, and the Art Nouveau movement, as well as Kinetoscopes similar to the illusionistic films of Georges Melies.
  • ...20 more annotations...
  • Columbia, according to Infinite, is to have set sail at the 1893 Fair, thus opening up a ripe array of potential themes stemming from real world history and politics, all of which get at least lip service in the game: Manifest Destiny, American Exceptionalism, racism, and religious conflict.
  • This all occurs, as with the first BioShock, within the framework of a first person shooter.
  • The first major choice that players of BioShock Infinite are presented with is whether they would like to publicly punish an interracial couple or not. You may choose to throw a ball at the couple, who are tied up in front of a crowd at a fair, or you may choose to throw the ball at the man who is asking you to do so. The outcome of your choice is mostly the same.
  • Let’s think about that for a moment. BioShock Infinite, the game that many would hope to point to as an example of how art and subtlety might be found in expensive, mainstream videogames, sets up its moral stakes by asking the player if they would like to be a violent bigot.
  • Would you like to be for or against?
  • This is thunderously stupid, and an insipid example of how terrifyingly low the bar is set for ‘intelligence’ in mainstream videogames
  • In taking the game seriously, I want to be as clear as possible: BioShock Infinite uses racism for no other reason than to make itself seem clever. Worse, it uses racism and real events in an incredibly superficial way—BioShock Infinite seeks not to make any meaningful statement about history or racism or America, but instead seeks to use an aesthetics of ‘racism’ and ‘history’ as a barrier to point to and claim importance.
  • puts the lie to the claim that by engaging with these themes, BioShock Infinite is the place to find substance in mainstream videogames.
  • At the real Wounded Knee, over three hundred Native Americans—the Lakota Sioux—were massacred. Many of them were unarmed. Some of them were children. These were real people, with real lives and real families. The victims were buried in a mass grave, and many of the US Cavalry who led the massacre were later awarded the Medal of Honor, a decision that remains shameful today.
  • I am certainly not saying that a videogame has no right to engage with such events. What I am saying is that when you use such a horrific historic event in art—in any media—you have a responsibility to get it right, to use it to say something worthwhile, to make the invocation count.
  • Wounded Knee, I believe, is not something you get to invoke in 2013 without also making a statement of sorts. The idea of publicly punishing interracial relationships, something that of course has happened in reality, is also not something you get to invoke in 2013 without making a statement.
  • “[Letting] the player decide how they feel,” is not respecting your audience’s intelligence in these situations; it is a cop-out of the highest order.
  • For a game that so explicitly aimed to take on racism through its 1912 setting, the politics of BioShock Infinite are defined by evasion.
  • Such nihilistic disapproval is the absence of a political position masquerading as shrewd criticism. It may seem worldly, but it allows BioShock Infinite to be controversial to no-one by treating everyone with equal contempt.
  • Let us get one thing straight, then: despite its desperation to be taken seriously, BioShock Infinite is not an intelligent work of art. It is a history-themed first person shooter, and it deserves no more or less respect than any other first person shooter.
  • You can argue that the faults of BioShock Infinite are the latest and most unfortunate result of the first-person genre that found bedrock in both Doom (reflexes and gore) and Myst (architecture and mystery) in the mid-1990s, two sharply different trajectories that have been bound into problematic convergence ever since. While the two genres remain fruitfully exploited in separation, all attempts at marrying the two—and thus discovering the elusive union of the shooter’s popularity and the exploration game’s more literary aspirations—have remained ill considered. In a way, mainstream videogames are still completely dumbfounded by Edge magazine’s famous 1994 criticism of Doom: “If only you could talk to these creatures.”
  • Maybe this is really the central problem of the game—how do you merge any kind of intelligent thematic exploration while taking unrestrained pleasure in shooting people in the face?
  • Where do those two circles converge in a Venn diagram?
  • By its conclusion, BioShock Infinite quickly forgets that it ever engaged with ideas of racism and American Exceptionalism in favour of a tangled Christopher Nolan puzzle plot about time travel. This is the sound of a thousand popguns going off, taking up the silent report of a giant cannon that failed to fire.
  • it remains difficult to point to a single videogame that is both artful, subtle and a successful mainstream videogame, and BioShock Infinite only muddies the waters further.
  •  
    "Can mainstream videogame makers present an artful, intelligent thematic exploration about real world history within a game dominated by scenes of unrestrained violence, asks Daniel Golding."
