We have been oversold on the base rate fallacy in probabilistic judgment from an empirical, normative, and methodological standpoint. At the empirical level, a thorough examination of the base rate literature (including the famous lawyer–engineer problem) does not support the conventional wisdom that people routinely ignore base rates. Quite the contrary, the literature shows that base rates are almost always used and that their degree of use depends on task structure and representation. Specifically, base rates play a relatively larger role (...) in tasks where base rates are implicitly learned or can be represented in frequentist terms. Base rates are also used more when they are reliable and relatively more diagnostic than available individuating information. At the normative level, the base rate fallacy should be rejected because few tasks map unambiguously into the narrow framework that is held up as the standard of good decision making. Mechanical applications of Bayes's theorem to identify performance errors are inappropriate when (1) key assumptions of the model are either unchecked or grossly violated, and (2) no attempt is made to identify the decision maker's goals, values, and task assumptions. Methodologically, the current approach is criticized for its failure to consider how the ambiguous, unreliable, and unstable base rates of the real world are and should be used. Where decision makers' assumptions and goals vary, and where performance criteria are complex, the traditional Bayesian standard is insufficient. Even where predictive accuracy is the goal in commonly defined problems, there may be situations (e.g., informationally redundant environments) in which base rates can be ignored with impunity. A more ecologically valid research program is called for. This program should emphasize the development of prescriptive theory in rich, realistic decision environments. (shrink)

For Vajrayana Buddhism, the now is an interval, a boundary, a point of tension and suspension with an atmosphere of uncertainty. It is a bifurcation point of variable length; its name is “bardo.” The bardo is immersed in the conventional, or “seeming” reality. It emerges from what is called the “unstained” ultimate or primordial emptiness or “basal clear light.” Further, the ultimate is not the sphere of cognition. Cognition, including cognition of time, belongs to conventional reality. Buddhahood, in contrast, is (...) a condition of uncompounded knowledge where basic mind blossoms without temporal or other cognitive distinctions, unmade, unfabricated, luminous and pristine. Cyclical existence involves both the ultimate and the conventional as it moves through six bardos—all of which are the effulgent of the basal clear light—until Buddhahood. The six are: the bardo of this life ; the bardo of dream; the bardo of meditation; the bardo of dying; the bardo of dharmata ; and the bardo of existence. Each realm is both ultimate and conventional, and has specific initiation-based yogas to investigate these differences. The process of transition from one to the next involves at least three bodies, one mind, and aspects of speech. In each bardo, the character of the now as embodiment and temporal knowing varies yet a complete and consistent cross-bardo yogic wisdom leads to its total cessation in the basal clear light; the now is extinguished. The author presents, from the viewpoint of a knowledgeable practitioner of over 30 years, an essay on Vajrayana Buddhist time, drawing implications for Fraser’s time typology. The essay will draw from English translations of significant older, tantric texts on dream yoga, deity yoga, the Chod, tantric time, the bardo of death, and empowerment. Useful practices that can be applied by the audience to test the tradition and author’s assertions will be suggested. (shrink)

_Published by Taylor & Francis Group for the American Association of Colleges for Teacher Education_ This _Handbook_ addresses the concept and implementation of technological pedagogical content knowledge -- the knowledge and skills that teachers need in order to integrate technology meaningfully into instruction in specific content areas. Recognizing, for example, that effective uses of technology in mathematics are quite different from effective uses of technology in social studies, teachers need specific preparation in using technology in each content area they will (...) be teaching. Offering a series of chapters by scholars in different content areas who apply the technological pedagogical content knowledge framework to their individual content areas, the volume is structured around three themes: What is Technological Pedagogical Content Knowledge? Integrating Technological Pedagogical Content Knowledge into Specific Subject Areas Integrating Technological Pedagogical Content Knowledge into Teacher Education and Professional Development The _Handbook of Technological Pedagogical Content Knowledge for Educators_ is simultaneously a mandate and a manifesto on the engagement of technology in classrooms based on consensus standards and rubrics for effectiveness. As the title of the concluding chapter declares, "It’s about time!" The American Association of Colleges for Teacher Education is a national, voluntary association of higher education institutions and related organizations. Our mission is to promote the learning of all PK-12 students through high-quality, evidence-based preparation and continuing education for all school personnel.

In lieu of an abstract, here is a brief excerpt of the content:My Ability to FlourishPaulette KoehlerIn twenty years of convulsions, I’ve never heard a neurologist mention the word “epilepsy.” Over this time, the intensity of my original simple partial seizures, “simple” signifying retained consciousness and “partial” indicating disturbances restricted to a specific area of my brain, grew to the complex level on my left temporal lobe. I believe this development was influenced by my use of prescribed medications. Several neurologists (...) from Los Angeles to San Francisco directed various electroencephalograms (EEGs), including a week–long, prescription–free EEG in the hospital; magnetic resonance imaging tests (MRIs); computed tomography (CT) scans anywhere from forty–five minutes to four hours each; and blood profiles to help determine my situation. For legal reasons, one neurologist even had me sign a release stating that he was not able to diagnose my situation.Test results present limited information about my brain and without ever saying, “I don’t know,” these neurologists communicated my test results by utilizing technical terms and thus not always answering my questions. After explaining that my head turns to the left while my right hand shakes, symptoms that have been recognized and reported by several friends and family members, my doctor replied that a seizure on the left side of my brain should cause my head to turn to the right and then changed the subject. I felt like asking, “Am I doing it wrong?”The brain is different from other parts of our anatomy in that it can’t be replaced like a kidney, heart or other organ. It cannot be removed like tonsils, an appendix or even a limb. It can be physically studied or repaired while functioning but the resulting percentage of survival or proper operation of the body after surgery is minimal and the number of people requiring such attention is so low that the amount is scanty. A dead brain limits the analysis of its functions.My “disabilities” involve spontaneous uncontrolled loss of consciousness, exhaustion, mood swings, and the suspension of driving privileges. Activity interference, extra naps, losing friends and not being able to get around are definite disadvantages. However, everyone needs to manage personal problems. No one is perfect.Public transit schedules and directions don’t always offer me the transportation I need. Fortunately, the combination of a bus ride with walking or running can serve my needs while also helping me to keep physically healthy.Limited benefits include discounted transit and the option to ride instead of walking or running. A trip to Nana’s on the train is always a treat.I’d rather not be branded “disabled” even though those who understand my situation address me with compassionate, sympathetic attention, [End Page E4] always asking how I physically feel. I feel fine. A seizure is only a quick, conscious loss of time and an occasional scrape on the knee. I’m more annoyed when I notice strangers looking suspiciously at my public transport discount card as if I don’t really deserve it.Like the “disability” brand, the medications I’ve taken, Dilantin, Neurontin, Depakote, Keppra and Lamictal, among others, all of which produced serious side effects without reducing the frequency of my seizures have only been a cover–up, preventing a search for the true cause and effective treatment of my seizures. Being identified as disabled has only limited my daily schedule. I am not disabled, as society has unfortunately characterized me.My seizures began in 1993, the year our FDA started approving rBGH, recombinant bovine growth hormone, man–made for the use on dairy cows to enhance their milk production. As a result, milk on the market increased while keeping the price from rising, as demonstrated in Economics I. Can the use of rBGH act on my brain in any way?One neurologist, in order to avoid the responsibility of inappropriate recommendations, presented his thoughts in the form of questions, encouraging me to consider options.“You’ve tried all of these medications?”“Has your diet alteration made any difference in your seizures?”“Have you tried organic foods?”His inquiries persuaded me to contemplate whether drugs are an answer to my problem, pay attention to differences in my life and...

During the mid-18th century, when electricity was coming into its own, natural philosophers began to entertain the possibility that electricity is the mysterious nerve force. Their attention was first drawn to several species of strongly electric fish, namely torpedoes, a type of African catfish, and a South American "eels." This was because their effects felt like those of discharging Leyden jars and could be transmitted along known conductors of electricity. Moreover, their actions could not be adequately explained by popular mechanical (...) theories. Many of the early documents supportive of the hypothesis of animal electricity were associated with the Dutch colonies in South America. This article presents and examines those documents, and shows how Dutch scientists on both sides of the Atlantic conducted experiments and communicated with each other in the 1750s and 1760s. It reveals the important roles played by inquisitive physicians and lovers of nature in South America, and by natural philosophers and collectors of exotic specimens in the Netherlands—learned men who began to make a credible case for animal electricity in some exciting places at a pivotal moment in time.

I agree with Gibbs that the message of the base rate literature reads differently depending on which null hypothesis is used to frame the issue. But I argue that the normative null hypothesis, H0: “People use base rates in a Bayesian manner,” is no longer appropriate. I also challenge Adler's distinction between unused and ignored base rates, and criticize Goodie's reluctance to shift research attention to the field. Macchi's arguments about textual ambiguities in traditional base rate problems suggest that empirical (...) testing is needed to tease apart the effects of problem clarification and problem framing. Macdonald's, Fletcher's and Snow's skepticism about the value of Bayesian methods in real world judgment tasks is treated as a challenge for the next generation of empirical base rate studies.

We accept Sunstein's claim that people often use moral heuristics to make judgments and decisions. However, in situations that include a risk of betrayal, we disagree with Sunstein about when the relevant moral heuristic may be said to “misfire.” We suggest that the moral heuristic people apply to avoid the possibility of safety-product betrayal may be reasonable.

Early psychosocial stress (e.g., parental divorce, abuse) is conjectured to place individuals on a developmental trajectory leading to earlier initiation of sexual activity, earlier reproduction, and having more sex partners than those with less early psychosocial stress. But does it also affect an individual’s mate choice? The present study examined whether early psychosocial stress affects preferences and dislikes for opposite-sex faces varying in masculinity/femininity, a putative indicator of mate quality, in premenopausal women (58 with a natural cycle, 53 pill-users) and (...) 196 men. No significant three-way interactions were found when women selected the most or least preferred face with participant group (natural cycle, pill), conception risk (low, high), and early psychosocial stress (low, high) as between-subjects factors. Early psychosocial stress did not affect men’s face preferences when selecting the most preferred face. However, men with high early psychosocial stress disliked masculine faces significantly more so than men with low early psychosocial stress. Overall it was concluded that early psychosocial stress does not affect mate choice with the exception that men with high early psychosocial stress were more likely to dislike masculine female faces. It was suggested that men with high early psychosocial stress may dislike masculine female faces because they have nothing to gain from associating with women with such faces. (shrink)

Commentators agree that simple conclusions about a general base rate fallacy are not appropriate. It is more constructive to identify conditions under which base rates are differentially weighted. Commentators also agree that improving the ecological validity of the research is desirable, although this is less important to those interested exclusively in psychological processes. The philosophers and ecologists among the commentators offer a kinder perspective on base rate reasoning than the psychologists. My own perspective is that the interesting questions (both psychological (...) and normative/prescriptive) are best answered through empirical studies that use real-world performance standards.

O objetivo deste artigo consiste em analisar como Nietzsche, baseado na filosofia schopenhauriana, resolveu o problema do surgimento da tragédia grega através da elevação dos elementos Apolo e Dionísio a um estatuto ontológico, e como os gregos fizeram isso em seu tempo através da Música, além de revelar como, em Nietzsche, o pensamento de Sócrates surge como o “perverso algoz da arte”.O estudo foi realizado através de uma pesquisa bibliográfica com base nas seguintes obras do filósofo: A visão Dionisíaca de (...) Mundo e O nascimento da tragédia no espírito da Música. Na segunda parte, sugere-se como Nietzsche faz esse resgate do trágico em sua época e qual a recepção no século XIX de seu trabalho. (shrink)
