One reason it's easier is that in C/C++ the . is used for value field access, while -> for pointer field access. In D, . is used for both. So you can easily switch between a value and a pointer to the value by changing little code.

Talent. A Football Scholarship. Then Crushing Depression. - The New York Times

Fri, 11/30/2018 - 17:24
"Maybe you have never heard of Isaiah Renfro. He did not start at the University of Washington, nor did he play in the N.F.L. But you should know his struggle. There are scores like him, young athletes on college campuses grappling with mental illness — a crisis that is only now getting serious attention. What experts know is this: Recent studies place suicide as the third leading cause of death for college athletes, behind motor vehicle accidents and medical issues. And nearly 25 percent of college athletes who participated in a widely touted 2016 study led by researchers at Drexel University displayed signs of depressive symptoms. Since that percentage is roughly in line with the general college population, the findings countered a long-held belief that athletes are less likely than their peers to become depressed — largely because they benefit from regular, emotion-lifting exercise. As the stigma of mental illness has eased, the reporting of cases has increased. But experts also believe that young athletes now face more stress, which contributes to mental illness, than ever before. “Performance and parental pressure, social media, more games on TV, more players who think they can go to the pros,” said Timothy Neal, the director of athletic training education at Concordia University in Ann Arbor, Mich., and a nationally recognized expert on mental health and college sports. The N.C.A.A. is playing catch-up. “We are still so young in addressing this,” said Brian Hainline, a neurologist who in 2013 became the N.C.A.A.’s first chief medical officer. He cited increasing concern not only about depression, but also about bipolar, eating, anxiety and attention deficit disorders, as well as addiction. “Mental health is our single most important priority.” What happened to Isaiah Renfro seemed to be a result of this combustible mix, where brain chemistry meets the burdens of reaching success and then maintaining it. He was hardly alone in his struggle."

The Real Enemy of Education Reform: It’s the Colleges, Stupid | The New Republic

Sun, 11/18/2018 - 01:33
"Colleges do very well under the status quo. And that’s bad for students and our economy." … "Where is all this money going? Many point to the rise of university administrator salaries and staffs. (You might know them as the college presidents complaining about all these changes Hillary Clinton and Barack Obama want to make to the higher education system.) Another possible culprit is bloated construction costs, which go toward building show palaces for…well, for the administrators to crow about, and attract more students to pay those high tuition rates. Whatever explanation appeals to you, the failures of the current system point clearly toward supplying a public debt-free option as a way to drive down costs. This would provide an anchor against skyrocketing costs, and force the cleanup of administrative bloat and unnecessary construction spending. You can force public colleges to lower costs as a condition of accepting tuition reimbursement. And if a glut of student loans causes prices to rise, then a free public option would reverse the effect. This goes back to the core issue: Incumbents prospering from a system don’t have much interest in seeing it change. And those wanting to reform the system must challenge those incumbents. It’s easier to single out the easy villains, the Sallie Maes and the Corinthian Colleges. But that just sidesteps the real opponent, and will lead to something far less than reform. Most colleges are seen in a fairly benevolent light. Large higher-education institutions are often major employers in their communities. They drive innovation, and provide sanctuary to some of our best thinkers. And for many adults, they are wrapped in the warm and fuzzy gauze of nostalgia. It’s hard to get people to see them as propping up a crisis that is over-burdening students and even stunting the growth of our economy. But until we do, it’s going to be very difficult to see any change."

We can’t educate our kids out of inequality | The Outline

Sun, 11/18/2018 - 01:32
"Those who tout the advantages of a good education like to conjure an image of some future society full of educated professionals all working stable, fulfilling, and salaried jobs. But even the worst students can look around the world and see through this. They can see the economic instability facing most people, and they know that a good education won’t undo the vagaries of the gig economy, or replace the protections of a union. But, they’re told, if you do well enough in school, then hopefully you won’t have to worry about that stuff. This false promise was more disheartening that any other realization I had while working with students. Unfair tests, confusing admissions policies, unequal schools — all that is bad but sadly unsurprising, so you can prepare yourself for it. On the other hand, I was not prepared to lie to students about how, if they just figured out trig functions, then everything would be OK. Education fetishism gives the illusion of fairness to society’s inequalities. Grades and test scores and college rankings mirror the stratification of the economy, and apply a thin veneer of meritocracy to that hierarchy. What students internalize about school is that it is primarily about ranking people. So attempts to improve education are really attempts to make those rankings more accurate, instead of making them less determinative. As long as this is true, then education is not really the solution to society’s problems. Even bold steps to improve schools and bring down college costs will not fix the problem of inequality, since status and sorting are also the results of education in America. None of this is to say that education is bad or that schools should not be improved for their own sake. Learning things, after all, is fun. Education is great when it’s about teaching people stuff they want to know. But because school has to serve this burden of fixing social problems it is not equipped to fix, it cannot simply teach students interesting things they want to learn. Students should learn trig functions because they are an elegant solution to a complicated problem. They should read Hamlet because it’s a good play. They should learn things because there is value in learning them. Instead, educators have to rend these subjects apart, breaking them into supposedly marketable skills like “reading comprehension” and “analytical reasoning” so that they can be used to demonstrate a student’s market value and justify patently unjust economic outcomes. As long as this is the case, then not only will inequality fail to get better, but education will continue to get worse. Instead of insisting we can educate ourselves out of the social problems capitalism creates, we should learn something new."

College campuses are far from radical | The Outline

Sun, 11/11/2018 - 21:06
"If you have considerable time on your hands and wish to see just what kind of leftists run universities, go to the graduate school and propose unionizing Research Assistants, Teaching Assistants, and other itinerant quasi-employees. You’ll discover quickly that senior faculty — the same ones who can’t wait to show you their picture with Tom Hayden or some other talisman of progressive cred — turn into staunch capitalists in a hurry. For the less adventurous, skip grad school and read up on the last two decades in which universities have been forced into the same “run it like a business” model that ruins every public good in this country. This is usually, if not exclusively, driven by GOP political appointees (as trustees) or vengeful GOP state legislative majorities looking to cut spending and score cheap political points with their constituents by showin’ them college boys the what-for. Administrative bloat — the plague of Dean-lets with highly-paid, nebulous titles like “Associate Dean of Library Engagement” that materialize out of nowhere — is real, and decision-making has become increasingly autocratic. Higher ups push for short-term results like CEOs trying to juice a quarterly earnings report, long-term consequences be damned. “Consultants” making twice faculty salaries for a few weeks of work appear and disappear mysteriously. Constant campaigns for “retention” — a code word for keeping students enrolled and paying tuition at all costs — push faculty toward grade inflation and dumbing-down. Expenses (read: labor costs) are forever squeezed, and demonstrably inferior products like online courses taught by some adjunct paid $2000 per semester are offered to Student-Customers happy to have them so long as they’re easy. More money is spent on administration and less is spent on instruction. Not quite the organizing principles of an egalitarian commune. Sounds more like the business model of any mundane corporation in America. Which brings us to the creep of corporate money into every aspect of university research and administration in the 21st Century — a fact that deals the Campus Commies premise a fatal blow. Nothing says “leftist hotbed” quite like Department of Biology, a Proud Partner of Monsanto. The cause for alarm, in fact, is that the direction of university teaching and research increasingly is dictated by donations from politically motivated billionaires and big corporations. If you believe that billions in donations from the Koch Brothers, Silicon Valley tech billionaires, and petrochemical companies is turning campuses ultra-liberal, you are beyond help. I don’t think Marx listed “aligning with corporate interests” as the final ideological step toward communism. None of this is to suggest that professors as a group should be more or less liberal, or that universities should be run more or less like businesses with corporate partners. The point is simply to illustrate the stupidity of the caricature of universities, faculty, and students as a barely-controlled gang of wild-eyed leftists. Were any of the incessant accusations from the right about the Ivory Tower true, campuses would be very different places to work and study. It is a febrile fantasy peddled to people who really enjoy yelling about things they don’t understand and who believe Kevin Sorbo films are documentaries."

Forschungsgruppe Dr. Feil » Kompetenz ist unsere Stärke » Thema: Kritik an Low Carb

Thu, 11/01/2018 - 11:09
Hallo Ihr, Low Carb ist nicht gleich Low-Carb. Wir empfehlen nicht unbedingt mehr Fleisch zu essen, sondern mehr hochwertige Fettsäuren und beim Eiweiß auf Qualität zu achten. Daher verschiebt sich auch das Eiweiß Verhältnis kaum. Gemüse bleibt bei uns nicht auf der Strecke sondern soll in Massen verzehrt werden. Das ist wichtig, damit der Körper auch leicht basisch bleibt und alle Reaktionen im Körper optimal ablaufen können. Das Gehirn übrigens kann nicht nur von Kohlenhydraten leben, sondern ist auch sehr gut im Verwerten von Keton-Körper (Abbau Produkte vom Fettstoffwechsel). Das lernt er allerdings nur, wenn er nicht so viele Kohlenhydrate bekommt. Gruß Friederike ... Hallo Achim, das ist ein ein Mythos. Fett macht nicht Fett und lagert sich auch nicht in Venen und Organen ein. Die Fettverbrennung läuft optimal, wenn wenig Kohlenhydrate genommen werden, sprich, wenn der Insulinspiegel niedrig ist. Bei vielen Kohlenhydraten in Form von Nudeln, Reis und Brot wird der Insulinspiegel jedes Mal erhöht und Fette können nicht mehr verbrannt werden. Sie bleiben in der Zelle. Dann lagern sich diese Fette auch in Arterien und Organe (z.B. Fettleber) ein, denn die Fettzellen fühlen sich überfordert. Allerdings nicht durch den Genuss von Fetten sondern durch den Genuss von Kohlenhydraten. Lassen Sie einfach mal nach der Umstellung mit wenig Kohlenhydraten in ein paar Wochen ihre Triglyceride beim Arzt untersuchen. Sie werden sehen, dass diese runter gegangen sind, sprich weniger Risiko für Ablagerungen. Gruß Friederike
