Human neural and behavioral activities have been reported to exhibit fractal dynamics known as 1/f noise, which is more aptly named 1/f scaling. Some argue that 1/f scaling is a general and pervasive property of the dynamical substrate from which cognitive functions are formed. Others argue that it is an idiosyncratic property of domain‐specific processes. An experiment was conducted to investigate whether 1/f scaling pervades the intrinsic fluctuations of a spoken word. Ten participants each repeated the word bucket over 1,000 (...) times, and fluctuations in acoustic measurements across repetitions generally followed the 1/f scaling relation, including numerous parallel yet distinct series of 1/f fluctuations. On the basis of work showing that 1/f scaling is a universal earmark of metastability, it is proposed that the observed pervasiveness of 1/f fluctuations in speech reflects the fact that cognitive functions are formed as metastable patterns of activity in brain, body, and environment.

The nonlinear dynamical process of self-organized criticality provides a new that explains a number of unresolved anomalies: Why are the really big events in human history usually unpredictable? Why is it impossible to anticipate sudden political, economic, and social changes? Why do distributions of historical data almost always contain a few extreme events that seem to have had a different cause from all the rest? Why do so many of our fail to predict important future events? As people, organizations, and (...) nations become increasingly sensitive to each other's behavior, trivial occurrences sometimes propagate into sudden changes. Such events are unpredictable because in the self-organized criticality environment that characterizes human history, the magnitude of a cause often is unrelated to the magnitude of its effect.

The ideas contained in Karl Popper's The Open Society and Its Enemies—one of the most important tracts in political philosophy in the twentieth century—are relevant to anyone seeking to understand the recent history of the East Asian economies. Even though Popper wrote his tract to provide an explanation for both the rise and objectionable nature of totalitarian regimes in Europe in the twentieth century, many of the arguments that he advanced in this European context also explain the social, political and (...) economic relationships that are seen in modern South Eastern Asian economies. The narrative of this book is driven by a research agenda that is inter-disciplinary in nature, since to make the link between the Popperian framework and East Asian socio-economic relationships the contributing authors needed to draw upon research fields as far apart as political philosophy and East-Asian studies. With one or two exceptions, however, nearly all of the contributing authors have a background in economics, and this background is reflected in the way that they have sought to tackle the research question. This book is, in short, an inter-disciplinary exercise undertaken from an economics perspective, and hence it may best be described as an exercise in political economy rather than pure analytical economics. The novelty of juxtaposing Popperian ideas with a discussion of social, political and economic development in South East Asia makes this narrative of interest to both political philosophers and specialists in South East Asian economies. The key insight drawn from the analysis is that although Karl Popper's The Open Society and Its Enemies was a product of a European time and place, it is also relevant to anyone seeking to understand the recent history of the East Asian economies.

Teaching bioethics with visual education tools, such as movies and comics, is a unique way of explaining the history and progress of human research and the art and science of medicine to high school students. For more than a decade, bioethical concepts have appeared in movies, and these films are useful for teaching medical and research ethics in high schools. Using visual tools to teach bioethics can have both interpretational and transformational effects on learners that will enhance their overall understanding (...) of complex moral and legal issues in medicine and research.High school students are uniquely suited to learn bioethics because they will soon become legal adults. As adults, they will make moral decisions that may affect their health and wellbeing as well as that of their communities and societies.However, not all visual education tools are appropriate for bioethics pedagogy in high school. Bioethics film and comic producers must consider the specifics of student age, race, gender, belief, level of education, and sexual orientation. Such tools must not be dominated by either dystopic or utopic genres, must aim for objectivity, and must consider the complexity of ethical decision making. It is critical that the teacher, who is the final arbiter regarding the use of visual tools in the classroom, determines that the visual learning tool is acceptable for students in any particular education context. In addition, during the conceptualization and creation of these tools, bioethics film and comic producers must work harder to ensure that these visual tools are devoid of any form of stereotyping.

Approximately one in two hundred persons in the Marshall Islands have active tuberculosis. We examine the historical antecedents of this situation in order to assign ethical responsibility for the present situation. Examining the antecedents in terms of Galtung’s dialectic of personal versus structural violence, we can identify instances in the history of the Marshall Islands when individual subjects made decisions with large-scale ecologic, social, and health consequences. The roles of medical experimenters, military commanders, captains of the weapons industry in particular, (...) and industrial capitalism in general are examined. In that, together with Lewontin, we also identify industrial capitalism as the cause of tuberculosis, we note that the distinction between personal versus structural violence is difficult to maintain. By identifying the cause of the tuberculosis in the Marshall Islands, we also identify what needs be done to treat and prevent it. (shrink)

This article focuses on mirror self-recognition, the ability to recognize one's own image in a mirror. It presents the result of the first experiment on mirror self-recognition which showed that chimpanzees are able to learn that the chimps they see in the mirror are not other chimps, but themselves, as evidenced by self-directed behaviour. It reviews evidence for neural network for self-recognition and self-other differentiation and cites evidence that frontal cortex and cortical midline structures are implicated in self-recognition tasks. It (...) also suggests that the mirror self-recognition ability correlates to large brain size relative to the animal's body size. (shrink)

Context Physicians are regularly confronted with research that is funded or presented by industry. Objective To assess whether physicians discount for conflicts of interest when weighing evidence for prescribing a new drug. Design and setting Participants were presented with an abstract from a single clinical trial finding positive results for a fictitious new drug. Physicians were randomly assigned one version of a hypothetical scenario, which varied on conflict of interest: ‘presenter conflict’, ‘researcher conflict’ and ‘no conflict’. Participants 515 randomly selected (...) Fellows in the American College of Obstetricians and Gynecologists' Collaborative Ambulatory Research Network; 253 surveys (49%) were returned. Main object measures The self-reported likelihood that physicians would prescribe the new drug as a first-line therapy. Results Physicians do not significantly discount for conflicts of interest in their self-reported likelihood of prescribing the new drug after reading the single abstract and scenario. However, when asked explicitly to compare conflict and no conflict, 69% report that they would discount for researcher conflict and 57% report that they would discount for presenter conflict. When asked to guess how favourable the results of this study were towards the new drug, compared with the other trials published so far, their perceptions were not significantly influenced by conflict of interest information. Conclusion While physicians believe that they should discount the value of information from conflicted sources, they did not do so in the absence of a direct comparison between two studies. This brings into question the effectiveness of merely disclosing the funding sources of published studies. (shrink)

Understanding how impactful scientific articles were funded informs future funding decisions. The structural significance of articles is broken down into two submeasures: citation count and “generativity”. Generativity is an attempt to provide a quantitative operationalization of transformativeness, a concept often used as a funding criterion despite not being a well-defined construct. This report identifies highly impactful and generative publications indexed in the subject area of psychology in the Web of Science in the year 2002. Publications that reported funding sources were (...) found to be more generative than those that did not, and research that was privately funded was found to be more generative than publicly funded research. This analysis is exploratory, and hopefully contributes to a foundation for future empirical investigations into the structure and nature of transformative science that granting agencies would want to fund.

This paper describes the application of eight statistical and machine-learning methods to derive computer models for predicting mortality of hospital patients with pneumonia from their findings at initial presentation. The eight models were each constructed based on 9847 patient cases and they were each evaluated on 4352 additional cases. The primary evaluation metric was the error in predicted survival as a function of the fraction of patients predicted to survive. This metric is useful in assessing a model’s potential to assist (...) a clinician in deciding whether to treat a given patient in the hospital or at home. We examined the error rates of the models when predicting that a given fraction of patients will survive. We examined survival fractions between 0.1 and 0.6. Over this range, each model’s predictive error rate was within 1% of the error rate of every other model. When predicting that approximately 30°K of the patients will survive, all the models have an error rate of less than 1.5%. The models are distinguished more by the number of variables and parameters that they contain than by their error rates; these differences suggest which models may be the most amenable to future implementation as paper-based guidelines.

This study investigated (1) whether potential future purchasing agents were predisposed to accept gratuities or whether the practice of gratuity acceptance is a manifestation of the job itself, (2) whether the existence of a code of ethics forbidding gratuity acceptance curtails the occurrence, and (3) whether disparities in ethics policies between the sales and purchasing functions affect gratuity acceptance. Hypotheses based upon the concepts of organizational concern and institutionalized ethics are developed and empirically tested. Results suggest that future purchasing agents (...) are predisposed to accept gratuities and that formal written ethics policies decrease the acceptance of gratuities. Disparities in ethics policies between the sales and purchasing functions concerning gratuities failed to affect gratuity acceptance significantly. (shrink)

This article places the issue of quoting practices in journalism - widely debated in public and professional forums since the Masson-Malcolm (Masson v. New Yorker Magazine, 1991) dispute - into both practical and ethical contexts. It suggests that the multitude of ethical dilemmas facing journalists in the handling of quotations can be addressed by adapting Bok's (1979) test of publicity, which requires that journalists willingly imagine themselves under scrutiny. The spirit of the test asks journalists to embrace this central orienting (...) rhetorical question: Is my behavior such that I'd be comfortable having all my audiences - interview subject, editor, public, and self - simultaneously monitor my choice(s), knowing that I might later be called upon to justify my actions.

The paper discusses Dr. Floris Tomasini's paper “What Is Bioethics: Notes toward a New Approach?”. Based on Tomasini's account of methodological and ethical pluralism, the paper explores the demarcation problem of bioethics and suggests a full methodological laissez-faire.

The purpose of this paper is to show that if one adopts conditional probabilities as the primitive concept of probability, one must deal with the fact that even in very ordinary circumstances at least some probability values may be imprecise, and that some probability questions may fail to have numerically precise answers.

This study examines the impact of Sarbanes–Oxley on the nonprofit sector. Focusing on three key SOX policies applicable to charities—conflict-of-interest policies, records retention policies, and whistleblower policies—this study tests the relationship between the existence and addition of these policies on subsequent ethical and governance lapses as reflected in the issuance of “donor advisories” by the large third-party ratings agency Charity Navigator. The findings suggest that, controlling for other relevant organizational factors, the three SOX-inspired written policies are related to a reduced (...) likelihood of donor advisories in the organizations rated by Charity Navigator.

Life history theory predicts that greater extrinsic mortality will lead to earlier and higher fertility. To test this prediction, I examine the relationship between life expectancy at birth and several proxies for life history traits (ages at first sex and first marriage, total fertility rate, and ideal number of children), measured for both men and women. Data on sexual behaviors come from the Demographic and Health Surveys (DHS). Two separate samples are analyzed: a cross-sectional sample of 62 countries and a (...) panel sample that includes multiple cross-sectional panels from 48 countries. Multivariate regression analysis is used to control for potential confounding variables. The results provide only partial support for the predictions, with greater support among women than men. However, the prediction is not supported in sub-Saharan African countries, most likely owing to the nonequilibrium conditions observed in sub-Saharan Africa with respect to life expectancy. The applicability of the model to understanding HIV/AIDS risk behaviors is discussed. (shrink)

An analysis of student learning with the LISP tutor indicates that while LISP is complex, learning it is simple. The key to factoring out the complexity of LISP is to monitor the learning of the 500 productions in the LISP tutor which describe the programming skill. The learning of these productions follows the power‐law learning curve typical of skill acquisition. There is transfer from other programming experience to the extent that this programming experience involves the same productions. Subjects appear to (...) differ only on the general dimensions of how well they acquire the productions and how well they retain the productions. Instructional manipulations such as remediation, content of feedback, and timing of feedback are effective to the extent they give students more practice programming, and explain to students why correct solutions work.

The hypothesis that father absence during childhood, as well as other forms of childhood psychosocial stress, might influence the timing of sexual maturity and adult reproductive behaviors has been the focus of considerable research. However, the majority of studies that have examined this prediction have used samples of women of European descent living in industrialized, low-fertility nations. This paper tests the father-absence hypothesis using the Cape Area Panel Study (CAPS), which samples young adults in Cape Town, South Africa. The sample (...) contains multiple racial groups (blacks, coloureds [mixed race], and whites) and includes both males and females. Dependent variables include age at menarche, age at first sexual intercourse, and age at first pregnancy. Childhood stress is measured by father absence by age six (either never lived with father or lived with father some but not all years) and an index of childhood exposure to violence (measuring threatened or actual verbal or physical abuse). The hypothesis received no support for effect on age at menarche but was supported for age at first sex and first pregnancy. The model showed stronger support for coloureds and whites than blacks and had no predictive power at all for black males. (shrink)
