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.

Self-esteem Human emotional need Self-esteem is confidence in one's own worth, abilities, or morals. Self-esteem encompasses beliefs about oneself (for example, "I am loved", "I am worthy") as well as emotional states, such as triumph, despair, pride, and shame.[1] Smith and Mackie define it by saying "The self-concept is what we think about the self; self-esteem, is the positive or negative evaluations of the self, as in how we feel about it (see self)."[2] The construct of self-esteem has been shown to be a desirable one in psychology, as it is associated with a variety of positive outcomes, such as academic achievement,[3][4] relationship satisfaction,[5] happiness,[6] and lower rates of criminal behavior. Self-esteem can apply to a specific attribute or globally. The concept of self-esteem has its origins in the 18th century, first expressed in the writings of the Scottish enlightenment thinker David Hume. Many early theories suggested that self-esteem is a basic human need or motivation. [edit]
<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.
Self-control In behavior analysis[edit] Another view is that self-control represents the locus of two conflicting contingencies of reinforcement, which then make a controlling response reinforcing when it causes changes in the controlled response.[2][3] Research[edit] Counteractive[edit] Desire is an affectively charged motivation toward a certain object, person, or activity that is associated with pleasure or relief from displeasure.[4] Desires vary in strength and duration. A desire becomes a temptation, entering the area of self-control, if the behavior resulting from the desire conflicts with an individual’s values or other self-regulatory goals.[5][6] A limitation to research on desire is the issue of individuals desiring different things. Desires that conflict with overarching goals or values are known as temptations.[6][8] Self-control dilemmas occur when long-term goals and values clash with short-term temptations.

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
Self-actualization Self-actualization is a term that has been used in various psychology theories, often in slightly different ways. The term was originally introduced by the organismic theorist Kurt Goldstein for the motive to realize one's full potential. Expressing one's creativity, quest for spiritual enlightenment, pursuit of knowledge, and the desire to give to society are examples of self-actualization. In Goldstein's view, it is the organism's master motive, the only real motive: "the tendency to actualize itself as fully as possible is the basic drive... the drive of self-actualization."[1] Carl Rogers similarly wrote of "the curative force in psychotherapy - man's tendency to actualize himself, to become his potentialities... to express and activate all the capacities of the organism In Goldstein's theory[edit] Maslow's hierarchy of needs[edit] Abraham Maslow's book Motivation and Personality started a philosophical revolution out of which grew humanistic psychology.

Rubicon model From Wikipedia, the free encyclopedia In psychological theories of motivation, the Rubicon model, more completely the Rubicon model of action phases, makes a distinction between motivational and volitional processes. The Rubicon model "defines clear boundaries between motivational and action phases." The name "Rubicon model" derives from the tale of Caesar's crossing the Rubicon River, a point of no return, thereby revealing his intentions. "Once subjects move from planning and goal-setting to the implementation of plans, they cross a metaphorical Rubicon. — Lyn Corno, The best laid plans, p. 15 (quoted by Rauber) The Rubicon model addresses four questions, as identified by Achtziger and Gollwitzer:[3] How do people select their goals? The study of these issues is undertaken by both the fields of cognitive neuroscience and social psychology. Background[edit] See also[edit] References[edit]
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?
Rosenberg self-esteem scale From Wikipedia, the free encyclopedia Self-report questionnaire The Rosenberg self-esteem scale (RSES), developed by the sociologist Morris Rosenberg,[1] is a self-esteem measure widely used in social science research. It uses a scale of 0–30, where a score less than 15 may indicate problematic low self-esteem.[2] Although the instrument was developed for use with adolescents, it has been widely used in research on adults.[3][4] The RSES is designed similar to the social-survey questionnaires. Five of the items have positively worded statements and five have negatively worded ones. The RSES has been translated and adapted to various languages, such as Persian,[6] French,[7] Chinese,[8] Italian,[9] German,[10] Portuguese,[11] and Spanish.[12] The scale is extensively used in cross-cultural studies in up to 53 different nations.[13] See also[edit] Psychological testing References[edit] ^ Rosenberg, M.

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.
