: Where there are cases of underdetermination in scientific controversies, such as the case of the molecular clock, scientists may direct the course and terms of dispute by playing off the multidimensional framework of theory evaluation. This is because assessment strategies themselves are underdetermined. Within the framework of assessment, there are a variety of trade-offs between different strategies as well as shifting emphases as specific strategies are given more or less weight in assessment situations. When a strategy is underdetermined, scientists (...) can change the dynamics of a controversy by making assessments using different combinations of evaluation strategies and/or weighting whatever strategies are in play in different ways. Following an underdetermination strategy does not end or resolve a scientific dispute. Consequently, manipulating underdetermination is a feature of controversy dynamics and not controversy closure.

The issue of the dimensionality of materialism and postmaterialism, and their impact on key social and personal indicators, has been a hotly debated topic for decades. This study sought to achieve two goals to further our understanding of these constructs. First, it assessed whether an interactive materialism–postmaterialism conceptualization could be expanded to predict outcomes related to well-being. Second, the study extended the interactive model by using Richins’ three dimensions of materialism instead of the unidimensional construct utilized in previous studies. Results (...) indicated that the interactive model successfully predicted three different measures of well-being, specifically physical symptoms, stress, and subjective vitality. Results are discussed in terms of extending materialism–postmaterialism theory, both with respect to refining the materialism construct as well as its associations with new criterion variables.

Although its roots can be traced to the 19th century, progress in the study of nonlinear dynamical systems has taken off in the last 30 years. While pertinent source material exists, it is strewn about the literature in mathematics, physics, biology, economics, and psychology at varying levels of accessibility. A compendium research methods reflecting the expertise of major contributors to NDS psychology, Nonlinear Dynamical Systems Analysis for the Behavioral Sciences Using Real Data examines the techniques proven to be the most (...) useful in the behavioral sciences. The editors have brought together constructive work on new practical examples of methods and application built on nonlinear dynamics. They cover dynamics such as attractors, bifurcations, chaos, fractals, catastrophes, self-organization, and related issues in time series analysis, stationarity, modeling and hypothesis testing, probability, and experimental design. The analytic techniques discussed include several variants of the fractal dimension, several types of entropy, phase-space and state-space diagrams, recurrence analysis, spatial fractal analysis, oscillation functions, polynomial and Marquardt nonlinear regression, Markov chains, and symbolic dynamics. The book outlines the analytic requirements faced by social scientists and how they differ from those of mathematicians and natural scientists. It includes chapters centered on theory and procedural explanations for running the analyses with pertinent examples and others that illustrate applications where a particular form of analysis is seen in the context of a research problem. This combination of approaches conveys theoretical and practical knowledge that helps you develop skill and expertise in framing hypotheses dynamically and building viable analytic models to test them.

The purpose of this article is to suggest how philosophy might play a key, if precisely delineated, role in the shaping of policy that leads educational development. The argument begins with a reflection on the nature of confidence in the relationship between philosophy and policy. We note the widespread resistance to abstract theorising in the policy community, disguising the enormous potential of a philosophical approach. Defending a philosophically equipped approach to policy, which is inevitably theoretically laden, we argue that philosophical (...) investigation should be construed not as an initial step anterior to the task of research, but as a way of standing in relation to evidence and policy making throughout the process of investigation and adjudication. To illustrate the distinctive contribution philosophy can make, we propose five interrelated stages where philosophical thinking plays a constitutive role in the full process of policy development, critique and instantiation.

The unexpected death of a child is one of the most challenging losses as it fractures survivors’ sense of parenthood and other layers of identity. Given that not all the bereaved parents who have need for support respond well to available treatments and that many have little access to further intervention or follow-up over time, online interventions featuring therapeutic writing and peer support have strong potential. In this article we explore how a group of bereaved mothers experienced the process of (...) participating in an online course in therapeutic writing for the integration of grief. Our research questions were: How do parents who have lost a child experience being part of an online course in therapeutic writing? What are the perceived benefits and challenges of writing in processing their grief? We followed an existential phenomenological approach and analyzed fieldwork notes (n= 13), qualitative data from the application and assessment surveys (n= 35;n= 21), excerpts from the journals of some participants (n= 3), and email correspondence with some participants (n= 5). We categorized the results in three meaning units: (1) where does my story begin? The “both and” of their silent chaos; (2) standing on the middle line: a pregnancy that does not end; (3) closures and openings: “careful optimism” and the need for community support. Participants experienced writing as an opportunity for self-exploration regarding their identities and their emotional world, as well as a means to develop and strengthen a bond with their children. They also experienced a sense of belonging, validation, and acceptance in the online group in a way that helped them make sense of their suffering. Online writing courses could be of benefit for bereaved parents who are grieving the unexpected death of a child, but do not replace other interventions such as psychotherapy. In addition to trauma and attachment informed models of grief, identity informed models with a developmental focus might enhance the impact of both low-threshold community interventions and more intensive clinical ones. Further studies and theoretical development in the area are needed, addressing dialogical notions such as the multivoicedness of the self. (shrink)

We propose that sociological theory should comprise a series of elementary and abstract principles on the operation of distinctive and generic social processes. These processes intersect and interact in varying combinations to create diverse social forms, including stratification. Six elementary principles, stated as simple equations, are developed for the social processes implicated in societal stratification.

We report the results of an experiment in which human subjects were trained to perform a perceptual matching task. Subjects were asked to manipulate comparison objects until they matched target objects using the fewest manipulations possible. An unusual feature of the experimental task is that efficient performance requires an understanding of the hidden or latent causal structure governing the relationships between actions and perceptual outcomes. We use two benchmarks to evaluate the quality of subjects’ learning. One benchmark is based on (...) optimal performance as calculated by a dynamic programming procedure. The other is based on an adaptive computational agent that uses a reinforcement-learning method known as Q-learning to learn to perform the task. Our analyses suggest that subjects were successful learners. In particular, they learned to perform the perceptual matching task in a near-optimal manner (i.e., using a small number of manipulations) at the end of training. Subjects were able to achieve near-optimal performance because they learned, at least partially, the causal structure underlying the task. In addition, subjects’ performances were broadly consistent with those of model-based reinforcement-learning agents that built and used internal models of how their actions influenced the external environment. We hypothesize that people will achieve near-optimal performances on tasks requiring sequences of action—especially sensorimotor tasks with underlying latent causal structures—when they can detect the effects of their actions on the environment, and when they can represent and reason about these effects using an internal mental model.

One facet of the control of gene expression is long‐range promoter regulation by distant enhancers. It is an important component of the regulation of genes that control metazoan development and has been appreciated for some time but the molecular mechanisms underlying this regulation have remained poorly understood. A recent study by Cleard and colleagues1 reports the first in vivo evidence of chromatin looping and boundary element promoter interaction. Specifically, they studied the function of a boundary element within the cis‐regulatory region (...) of the Abdominal‐B (Abd‐B) gene of Drosophila melanogaster.

Japanese Frames of Mind addresses two main questions in light of a collection of research conducted by both Japanese and American researchers at Harvard University: What challenge does Japanese psychology offer to Western psychology? Will the presumed universals of human nature discovered by Western psychology be reduced to a set of 'local psychology' among many in a world of unpredicted variations? The chapters provide a wealth of new data and perspectives related to aspects of Japanese child development, moral reasoning and (...) narratives, schooling and family socialization, and adolescent experiences. By placing the Japanese evidence within the context of Western psychological theory and research, the book calls for a systematic reexamination of Western psychology as one psychology among many other ethnopsychologies. Written in mostly non-technical language, this book will appeal to developmental and cultural psychologists, anthropologists interested in psychological anthropology, educators, and anyone interested in Japanese and Asian studies.

Ethical decision-making in public health rarely involves simply avoiding a bad choice in favor of a good choice. Instead, it requires policymakers to strike a balance among conflicting goals that are all good—goals such as the health of populations and individuals, knowledge gained through scientific research, autonomy, social justice, and the efficient use of limited resources. This balance can be elusive, and perfect examples are the legal instruments governing dual-use research, a term describing scientific endeavors meant to produce beneficial knowledge (...) or technology, but that could also be misapplied. Dual-use research of concern policies were implemented... (shrink)

The AIDS crisis poses a special challenge for American health care, which depends heavily on private insurance to pay medical bills. Can we provide adequate health care to all who need it and still meet the financial requirements of the private health insurance industry? More insurance carriers are turning to antibody testing in order to eliminate poor risks from non‐group, direct‐pay pools. Some cost‐conscious employers have attempted to fire AIDS patients summarily or to exclude AIDS coverage from group insurance policies. (...) Various remedies are available for spreading the financial risks of the epidemic, such as covering persons with AIDS under Medicare or in state‐sponsored health insurance pools. Ethical questions about cost and access may also rekindle the debate about the need for national health insurance. (shrink)

To promote ethical practices, healthcare managers must understand the ethical challenges encountered by key stakeholders. To characterize ethical challenges in Veterans Administration facilities from the perspectives of managers, clinicians, patients, and ethics consultants. We conducted focus groups with patients and managers ; semi-structured interviews with managers, clinicians, and ethics committee chairpersons. Data were analyzed using content analysis. Managers reported that the greatest ethical challenge was fairly distributing resources across programs and services, whereas clinicians identified the effect of resource constraints on (...) patient care. Ethics committee chairpersons identified end-of-life care as the greatest ethical challenge, whereas patients identified obtaining fair, respectful, and caring treatment. Perspectives on ethical challenges varied depending on the respondent's role. Understanding these differences can help managers take practical steps to address these challenges. Further, ethics committees seemingly, are not addressing the range of ethical challenges within their institutions. (shrink)

Defining and implementing Corporate Responsibility can be a challenge for many businesses. The identification of patterns in the processes of adoption and implementation of Corporate Responsibility practices can help managers to administer these processes more ably. In this research note, the authors identify four factors influencing the adoption and implementation of Corporate Responsibility practices: internal drivers; organizational structures; attributes of practice; and formal processes. Results indicate that there is also a continuous improvement component, meaning that the adoption and implementation of (...) Corporate Responsibility practices are cyclical, rather than linear, processes. (shrink)

The collusive relationship between the U.S. Forest Service and the lumber industry substantially harms the public interest, and inspires Congressional clearcutting and stumping policies. An anthropocentric1 (or homocentric) culture milieu fosters destruction of America''s old growth forests which results in ethically-relevant questions. It is proposed that corporate moral responsibility be extended to indirect stakeholders and that a transcendent environmental ethic, biocentrism2 (or deep ecology), oblige management to expand the sphere of external stakeholders to include environment objects such as animals, trees, (...) and biotic communities.

Contemporary commentators on Hume's essay, ‘Of miracles’ have increasingly tended to argue that Hume never intended to suggest that testimonial evidence must always be insufficient to justify belief in a miracle. This is in marked contrast to earlier commentators who interpreted Hume as intending to demonstrate that testimonial evidence is incapable in principle of ever establishing rational belief in a miracle. In this article I argue that this traditional interpretation is the correct one.

Although ethics consultation is offered as a clinical service in most hospitals in the United States, few valid and practical tools are available to evaluate, ensure, and improve ethics consultation quality. The quality of ethics consultation is important because poor quality ethics consultation can result in ethically inappropriate outcomes for patients, other stakeholders, or the health care system. To promote accountability for the quality of ethics consultation, we developed the Ethics Consultation Quality Assessment Tool. ECQAT enables raters to assess the (...) quality of ethics consultations based on the written record. Through rigorous development and preliminary testing, we identified key elements of a quality ethics consultation, established scoring criteria, developed training guidelines, and designed a holistic assessment process. This article describes the development of the ECQAT,.. (shrink)
