The visual world of adults consists of objects at various distances, partly occluding one another, substantial and stable across space and time. The visual world of young infants, in contrast, is often fragmented and unstable, consisting not of coherent objects but rather surfaces that move in unpredictable ways. Evidence from computational modeling and from experiments with human infants highlights three kinds of learning that contribute to infants’ knowledge of the visual world: learning via association, learning via active assembly, and learning (...) via visual-manual exploration. Infants acquire knowledge by observing objects move in and out of sight, forming associations of these different views. In addition, the infant’s own self-produced behavior—oculomotor patterns and manual experience, in particular—is an important means by which infants discover and construct their visual world.

Adults and infants display a robust ability to perceive the unity of a center-occluded object when the visible ends of the object undergo common motion (e.g. Kellman, P.J., Spelke, E.S., 1983. Perception of partly occluded objects in infancy. Cognitive Psychology 15, 483±524). Ecologically oriented accounts of this ability focus on the primacy of motion in the perception of segregated objects, but Gestalt theory suggests a broader possibility: observers may perceive object unity by detecting patterns of synchronous change, of which common (...) motion is a special case. We investigated this possibility with observations of adults and 4-month-old infants. Participants viewed a center-occluded object whose visible surfaces were either misaligned or aligned, stationary or moving, and unchanging or synchronously changing in color or bright- ness in various temporal patterns (e.g. ¯ashing). Both alignment and common motion con- tributed to adults' perception of object unity, but synchronous color changes did not. For infants, motion was an important determinant of object unity, but other synchronous changes and edge alignment were not. When a stationary object with aligned edges underwent syn- chronous changes in color or brightness, infants showed high levels of attention to the object, but their perception of its unity appeared to be indeterminate. An inherent preference for fast over slow ¯ash rates, and a novelty preference elicited by a change in rate, both indicated that infants detected the synchronous changes, although they failed to use them as information for object unity. These ®ndings favor ecologically oriented accounts of object perception in which surface motion plays a privileged role. Ó 1999 Elsevier Science B.V. All rights reserved. (shrink)

This is a well-behaved concept in Newtonian physics. But a center of gravity is not an atom or a subatomic particle or any other physical item in the world. It has no mass; it has no color; it has no physical properties at all, except for spatio-temporal location. It is a fine example of what Hans Reichenbach would call an abstractum. It is a purely abstract object. It is, if you like , a theorist's fiction. It is not one of (...) the real things in the universe in addition to the atoms. But it is a fiction that has nicely defined, well delineated and well behaved role within physics. (shrink)

"Over three years of study and fellowship, sixteen Muslim, Jewish, and Christian scholars sought to answer one question: “Do our three scriptures unite or divide us?” They offer their answers in this book: sixteen essays on how certain ways of reading scripture may draw us apart and other ways may draw us, together, into the source that each tradition calls peace. Reading scriptural sources in the classical and medieval traditions, the authors examine how each tradition addresses the “other” within its (...) tradition and without, how all three traditions attend to poverty as a societal and spiritual condition, and what it means to read scripture while facing the challenges of modernity. Ochs and Johnson have assembled a unique approach to inter-religious scholarship and a rare look at scriptural study as a pathway to peace. “Scriptural reasoning, the growing practice of Jews, Christians, and Muslims reading their scriptures together, makes good academic and common sense in a time of crisis. This ground-breaking book, the outcome of an imaginative 3-year experiment by the Princeton Center of Theological Inquiry, shows scholars and thinkers of the Abrahamic traditions going deeper into the traditions and into their contemporary situation. The result is something new, wise, and relevant… full of promise for the future. Where else can one find testimonies to Jews, Christians, and Muslims coming together not only in study, thinking, and wisdom-seeking but also in play, joy, and friendship?”--David F. Ford, Regius Professor of Divinity, University of Cambridge and Director, Cambridge Inter-Faith Programme". (shrink)

Inferences about spatial, temporal, and other relations are ubiquitous. This article presents a novel model-based theory of such reasoning. The theory depends on 5 principles. The structure of mental models is iconic as far as possible. The logical consequences of relations emerge from models constructed from the meanings of the relations and from knowledge. Individuals tend to construct only a single, typical model. They spontaneously develop their own strategies for relational reasoning. Regardless of strategy, the difficulty of an inference depends (...) on the process of integration of the information from separate premises, the number of entities that have to be integrated to form a model, and the depth of the relation. The article describes computer implementations of the theory and presents experimental results corroborating its main principle. (shrink)

Given a basic conditional of the form, If A then C, individuals usually list three cases as possible: A and C, not‐A and not‐C, not‐A and C. This result corroborates the theory of mental models. By contrast, individuals often judge that the conditional is true only in the case of A and C, and that cases of not‐A are irrelevant to its truth or falsity. This result corroborates other theories of conditionals. To resolve the discrepancy, we devised two new tasks: (...) the “collective” truth task, in which participants judged whether sets of assertions about a specific individual, such as: If A then C, not‐A, C, could all be true at the same time; and one in which participants judged the truth of conditional predictions about specific future events. The results consistently matched the three possibilities, thereby corroborating the model theory. They also showed a massive violation of the probability calculus in estimates of the probabilities of the four cases in the partition of conditionals (A and C, A and not‐C, not‐A and C, and not‐A and not‐C), which summed to over 200%.

Is it socially responsible to price at a premium, company branded generic pharmaceuticals in emerging economies? Building toward an answer to this question, the study first describes the role of the branded generic sector in the economic success of the global pharmaceutical industry. Second, the concept of “shared value,” i.e., the link between competitive advantage and corporate social responsibility, is introduced and applied to the global pharmaceutical industry’s position on marketing generic pharmaceuticals. Third, an empirical evaluation ascertains whether there is (...) sufficient shared value for this company branded generics pricing strategy to be considered “socially responsible.” Fourth, after concluding there is sufficient shared value, a discussion section offers a public/private framework that will help ensure that safe and effective pharmaceuticals are sold to consumers in developing economies. Lastly, a summary and conclusion section completes the article. (shrink)

This exploratory study of ethical decision making by individuals in organizations found moral intensity, as defined by Jones (1991), to significantly influence ethical decision making intentions of managers. Moral intensity explained 37% and 53% of the variance in ethical decision making in two decision-making scenarios. In part, the results of this research support our theoretical understanding of ethical/unethical decision-making and serve as a foundation for future research.

Salient stimuli presented at unattended locations are not always perceived, a phenomenon termed inattentional blindness. We hypothesized that inattentional blindness may be mediated by attentional inhibition. It has been shown that attentional inhibition effects are maximal near an attended location. If our hypothesis is correct, inattentional blindness effects should similarly be maximal near an attended location. During central fixation, participants viewed rapidly presented colored digits at a peripheral location. An unexpected black circle was concurrently presented. Participants were instructed to maintain (...) central fixation and name each color/digit, requiring focused attention to that location. For each participant, the critical stimulus was presented either near to or far from the attended location . In support of our hypothesis, inattentional blindness effects were maximal near the attended location, but only at intermediate task accuracy. (shrink)

Accounting ethics failures have seized headlines and cost investors billions of dollars. Improvement of the ethical reasoning and behavior of accountants has become a key concern for the accounting profession and for higher education in accounting. Researchers have asked a number of questions, including what type of accounting ethics education intervention would be most effective for accounting students. Some researchers have proposed virtue ethics as an appropriate moral framework for accounting. This research tested whether Smithian virtue ethics training, based on (...) Adam Smith’s “The Theory of Moral Sentiments”, is effective in improving accounting student’s cognitive moral development. This research used a pre-test, treatment, post-test, quasi-experimental design utilizing the Defining Issues Test 2 instrument to measure students’ CMD. Analysis of DIT-2 gain scores did show a significant improvement in subjects’ personal interest scores and a significant improvement in an overall measure of CMD, the DIT N2 index, whereas their DIT-2 post-conventional scores did not improve significantly. This research supports the proposition that the concepts contained in Smithian virtue ethics can contribute to an effective accounting ethics education intervention. However, further research is required to determine what concepts should be included to improve accounting students’ post-conventional moral reasoning. (shrink)

In Discovering Alabama Forests, ecologist-educator Doug Phillips and photographer Robert Falls celebrate the current health and diversity of Alabama woodlands while sounding a call for their wise management and protection in the future.

In the United States of America, and in much of the world, corporations are afforded a great deal of rights to both protect themselves and others against legal action and mistreatment. To gain these rights, they defended themselves or were defended many times throughout the years in courts under the framework of “legal personhood”—but this same legal personhood is not afforded to most actual living creatures. There is enough similarity in the legal framework afforded to corporations that should be afforded (...) to animals as well, and more than enough evidence to show that it is increasingly necessary to protect and expand animal rights in this way. The argument is simple: because of their sentience, cognition, and emotional intelligence, animals deserve legal personhood. If we can make the argument that a corporation, which is incapable of these things listed above, should have certain unalienable rights, then it is illogical for us to make the argument that animals should not.

This volume attempts to show why ontology matters for a proper grasp of issues in bioethics. -/- Contemporary discussions on bioethics often focus on seeking solutions for a wide range of issues that revolve around persons. The issues in question are multi-layered, involving such diverse aspects as the metaphysical/ontological, personal, medical, moral, legal, cultural, social, political, religious, and environmental. In navigating through such a complex web of issues, it has been said that the central problems philosophers and bioethicists face are (...) ethical in nature. In this regard, biomedical sciences and technological breakthroughs take a leading role in terms of shaping the sorts of questions that give rise to ethical problems. For example, is it ethical to keep terminally ill patients alive on dialysis machines or artificial ventilators? Is it ethical to take someone’s vital organs upon death and transplant them into another person’s body without any prior consent from a deceased person? Reproductive techniques also raise complicated ethical issues involving in vitro fertilization, contraceptives, prenatal testing, abortions, and genetic enhancements. Moreover, biomedical issues raise ethical problems in regards to research on human subjects, stem cell research, and enhancement biotechnology. The beginning and end of life issues bring up their own complicated ethical conundrums involving, among other things, terminating life support and euthanasia. -/- This book approaches such complex bioethical questions by engaging in ground-level debates about the ontology of persons. This is a non-negotiable first step in taking steps forward in seeking a plausible solution(s) for the complex ethical problems in bioethics. Although the contributors in this book advance their arguments in their own ways, they all agree on one crucial methodological point: the importance of taking the ontology of persons for bioethics seriously. This is the spirit that brings the contributors of this book together as they seek to build their case(s) concerning the nature of persons. (shrink)

Few studies exist which look at psychological factors associated with physician sexual misconduct. In this study, we explore family dysfunction as a possible risk factor associated with physician sexual misconduct. Six hundred thirteen physicians referred to a continuing medical education (CME) course for sexual misconduct were administered the FACES-II survey, a validated and reliable measure of family dynamics. The survey was part of a self-learning activity. We collected data from February 2000 to February 2009. Participants were predominantly white, middle-aged males (...) who represented the full range of medical specialties. Their results were compared against a sample of 177 physicians. The FACES-II is a self-report test that measures family of origin (the family in which one was raised) dynamics on two dimensions (1) flexibility, ranging from too flexible (chaotic) to not flexible enough (rigid) and (2) cohesion ranging from too close (enmeshed) to not close enough (disengaged). The most common family pattern observed among physicians accused of sexual misconduct was rigid flexibility paired with disengaged cohesion, indicative of unhealthy family functioning. This pattern was significantly different than the pattern observed in the comparison group. Physicians who engage in sexual misconduct are more likely to have family of origin dysfunction. Ethics is developmental and learned in one’s family of origin. Family of origin dynamics may be one risk factor predisposing one to ethical violations. These findings have important implications for screening, education, and treatment across the medical education continuum. (shrink)

Second harmonic generating (SHG) nanoprobes have recently emerged as versatile and durable labels suitable for in vivo imaging, circumventing many of the inherent drawbacks encountered with classical fluorescent probes. Since their nanocrystalline structure lacks a central point of symmetry, they are capable of generating second harmonic signal under intense illumination – converting two photons into one photon of half the incident wavelength – and can be detected by conventional two‐photon microscopy. Because the optical signal of SHG nanoprobes is based on (...) scattering, rather than absorption as in the case of fluorescent probes, they neither bleach nor blink, and the signal does not saturate with increasing illumination intensity. When SHG nanoprobes are used to image live tissue, the SHG signal can be detected with little background signal, and they are physiologically inert, showing excellent long‐term photostability. Because of their photophysical properties, SHG nanoprobes provide unique advantages for molecular imaging of living cells and tissues with unmatched sensitivity and temporal resolution. (shrink)
