Self-efficacy

Self-efficacy
Self-efficacy is the extent or strength of one's belief in one's own ability to complete tasks and reach goals.[1] Psychologists have studied self-efficacy from several perspectives, noting various paths in the development of self-efficacy; the dynamics of self-efficacy, and lack thereof, in many different settings; interactions between self-efficacy and self-concept; and habits of attribution that contribute to, or detract from, self-efficacy. This can be seen as the ability to persist and a person's ability to succeed with a task. As an example, self-efficacy directly relates to how long someone will stick to a workout regimen or a diet. High and low self-efficacy determine whether or not someone will choose to take on a challenging task or "write it off" as impossible. Self-efficacy affects every area of human endeavor.

הבעיה של גוגל: צירוף של מספרים לא בהכרח מניב מסקנות נכונות - גלובל - אתר חדשות כלכלה ונתוני בורסה מישראל ומהעולם TheMarker דה מרקר ניק בילטון מ"ניו יורק טיימס": "אנחנו ממהרים להשתמש בנתונים של גוגל ושוכחים כי מדובר באסופת מספרים שמתעלמת מההקשר" לפני מספר שנים גוגל יצרה משוואה מפוארת שיכולה לפענח כמה אנשים חולים ברגע מסוים בשפעת. החשבון עבד כך: מיקום האדם יחד עם חיפוש הקשור לשפעת במנוע גוגל בתוספת אלגוריתמים חכמים במיוחד: מספר האנשים בארה"ב החולים בשפעת. ניק בילטון מספר בבלוג ב"ניו יורק טיימס" כי בעוד לפי נתוני גוגל, בחורף הנוכחי 11% מאוכלוסית ארה"ב היתה חולה בשפעת, ולפי מאמר שפורסם במגזין המדעי Nature, האלגוריתמים של גוגל שגויים והתוצאות כפולות לעומת הנתונים של המרכז האמריקאי לפיקוח על מחלות שמדווח על 6% מהאמריקאים חלו בשפעת. לפי בילטון, ייתכן שהבעיה באלגוריתם של גוגל היא כי הוא מסתכל על מספרים, ולא על תוכן. "בעולם של היום, המידע נמצא בכל מקום. בילטון מוסיף חוויה דומה שהתרחשה כאשר לימד באוניברסיטת ניו יורק ב-2010. לפי תוצאות הניסוי, סטודנטים השתמשו במעליות בשעות הבוקר, כנראה כי עוד היו עייפים מהלילה, ובלילות עברו לשימוש במדרגות.

Here Comes Everybody This article is about the book. For the fictional character, see Finnegans Wake. Here Comes Everybody: The Power of Organizing Without Organizations is a book by Clay Shirky published by Penguin Press in 2008 on the effect of the Internet on modern group dynamics and organization. The title of the work alludes to HCE, a recurring and central figure in James Joyce's Finnegans Wake.[2] Synopsis[edit] In the book, Shirky recounts how social tools such as blogging software like WordPress and Twitter, file sharing platforms like Flickr, and online collaboration platforms like Wikipedia support group conversation and group action in a way that previously could only be achieved through institutions. "[Every] institution lives in a kind of contradiction: it exists to take advantage of group effort, but some of its resources are drained away by directing that effort.

<FM modulated doppler radar for human gesture sensing> a measurement device by Godfried-Willlem Raes a doppler radar based gesture measurement system capable of delivering positional information by dr.Godfried-Willem Raes postdoctoral researcher Ghent University College & Logos Foundation This technical note is a continuation of reports on many earlier designs for gesture sensing apparatus using both sonar and radar technologies. Doppler based microwave devices can be used to make pretty good movement sensors with a range from very nearby to about 20 meters. For the project we are reporting here, the following devices are examined: MDU1100 (Microwave Solutions Ltd.): X-band, operating microwave frequency is specified at 10.587 GHz. MDU2400 (Microwave Solutions Ltd).: K-band, operating microwave frequency 24.2 GHz. RSM1700 (Conrad), IPM170 (Microsense), Amiwima DRM-24 (Allsat Gmbh) devices operating around 24.125 GHz. Doppler formula: fd = 2 v fo / c fo = operational frequency c = speed of light fd = Doppler frequency v = movement speed in line with the antenna expressed in m/s Software Dr.

When Profits Can Take a Back Seat to Doing Good A brownie supplier to Ben & Jerry's ice cream, a skateboard maker and a payday lender are among the hundreds of existing businesses that plan to incorporate as "benefit corporations" in coming months. They will be taking advantage of a new and untested corporate charter, available in only a half dozen states, allowing a company's governing board to consider social or environment objectives ahead of profits. The legal structure is intended to shield the board from investor lawsuits. That anything other than maximizing shareholder value should be considered in a company's decision-making normally can open the door to investor suits. But in the past two years, lawmakers in seven states, including Maryland, Virginia and New Jersey, passed legislation to create benefit corporations as an alternative business model. California opened up the option Jan 1. In Mr. The benefit corporation isn't tax-exempt, nor is it a nonprofit. The idea has its share of critics. Mr.

Big-Bang Disruption By now any well-read executive knows the basic playbook for saving a business from disruptive innovation. Nearly two decades of management research, beginning with Joseph L. Bower and Clayton M. Christensen’s 1995 HBR article, “Disruptive Technologies: Catching the Wave,” have taught businesses to be on the lookout for upstarts that offer cheap substitutes to their products, capture new, low-end customers, and then gradually move upmarket to pick off higher-end customers, too. When these disrupters appear, we’ve learned, it’s time to act quickly—either acquiring them or incubating a competing business that embraces their new technology. But the strategic model of disruptive innovation we’ve all become comfortable with has a blind spot. That advice hasn’t been much help to navigation-product makers like TomTom, Garmin, and Magellan. The disruption here hasn’t come from competitors in the same industry or even from companies with a remotely similar business model. A Difference in Kind

IS SOCIAL-ACTUALIZATION REPLACING SELF-ACTUALIZATION? | Chip Conley First posted on Huffington Post 11.6.12 Self-actualization? Abraham Maslow’s Hierarchy of Needs pyramid with “being all you can be” at the top (co-opted by the U.S. Army as a marketing slogan) was a wake-up call for Americans in the 1950s when personal behavior and goals were so influenced by predominant societal ways. Abe’s humanistic psychology theory was made for the 60s with the advent of hippie culture and the idea that we should all “follow our bliss.” Unfortunately, Maslow died young in 1970 at age 62 and the “Me Decade” turned “self-actualization” into “self-absorption.” It’s been more than five years since I wrote PEAK: How Great Companies Get Their Mojo from Maslow where I outlined how my boutique hotel company reinterpreted Maslow’s theory to transform our organization at the bottom of a deep economic downturn. I see just how important Maslow’s theory was in reaction to the stifling social rules of mid-20th century America.

Eight UX Design Trends for 2013 One of the best things about user experience design is that the consumer products and services it helps to crystallize are always evolving. With that level of change comes all sorts of speculation about the future. Speculating is fun.

Should we be suspicious of the Anthropocene? – Jedediah Purdy Officially, for the past 11,700 years we have been living in the Holocene epoch. From the Greek for ‘totally new’, the Holocene is an eyeblink in geological time. In its nearly 12,000 years, plate tectonics has driven the continents a little more than half a mile: a reasonably fit person could cover the scale of planetary change in a brisk eight-minute walk. But the real news in the Holocene has been people. Popular now What will our descendants judge as our greatest sin? Why God knows more about misbehaviour than anything else If your memory fails, are you still the same person? This is why, from the earth sciences to English departments, there’s a veritable academic stampede to declare that we live in a new era, the Anthropocene – the age of humans. The lack of an official decision has set up the Anthropocene as a Rorschach blot for discerning what commentators think is the epochal change in the human/nature relationship. Enjoying Aeon?

InSight team's wearable glass system identifies people by clothes (Phys.org) —Researchers from the University of South Carolina and Duke are proposing a "visual fingerprint" app that can be used with smartphones and wearable camera displays such as Google Glass. Their paper, "Recognizing Humans without Face Recognition," explored techniques that can jointly leverage camera-enabled glasses, an offering that is still in the wings, and phones, to pick out any individual based on what the person is wearing. The team behind the InSight project developed and tested a prototype system that can pick out people by their clothes and other accessories. The system was developed by Srihari Nelakuditi, associate professor of computer science and engineering at the University of South Carolina, along with three colleagues at Duke University, He Wang, Xuan Bao, and Romit Roy Choudhury. How InSight works: A smartphone app creates a person's "fingerprint" by taking a series of pictures of the person. What's the point of the app? What's the limitation?

Can Benefit Corporations Work? In recent years, Warby Parker has become the eyeglass-maker of choice for hipsters. In a recent GQ taxonomy of the different varieties of nerd, all but one of the nerds were wearing a pair of Warby Parkers. The company’s approach—selling stylish specs at affordable prices—seems obvious, but, in an industry where brand-name glasses cost two or three hundred dollars a pair, it counts as revolutionary. There are now more than a thousand B corps in the U.S., including Patagonia, Etsy, and Seventh Generation. Why would any company tie its hands this way? Being a B corp also insulates a company against pressure from investors. In today’s fiercely competitive business environment, one might assume that a company that thinks altruistically is doomed to failure. It’s easy to be skeptical of the mushy rhetoric surrounding B corps.

Image 2: A comparison between the (ground truth) image being focused on the sensor surface and the reconstructed image (inset). WASHINGTON, Feb. 20, 2013— Digital cameras, medical scanners, and other imaging technologies have advanced considerably during the past decade. The new imager, which resembles a flexible plastic film, uses fluorescent particles to capture incoming light and channel a portion of it to an array of sensors framing the sheet. For the luminescent concentrator to work as an imager, Bimber and his colleagues had to determine precisely where light was falling across the entire surface of the film.
