Exploring the space of cognitive architectures

Production systems have been proposed as a candidate for the basic architecture of the human information processor. We consider a number of dimensions along which production systems can vary, and we discuss PRISM, a production system formalism designed to aid cognitive modelers in their exploration of the space of architectures. Examples of PRISM settings are presented in the context of particular models. Finally, some heuristics are suggested for efficiently searching the space of possible architectures.     

Principles and theory in bioethics.

The following citations were selected from BIOETHICSLINE, the online database prepared at the Kennedy Institute of Ethics for the National Library of Medicine's MEDLARS system. Searching the keywords autonomy, beneficence, casuistry, justice, and virtues, as well as the text word principlism produced more than 400 citations. Only the citations concerned with theory and principle in the practice of bioethics are included here -- e.g., works about justice in resource allocation have been deleted.     

When knowing becomes remembering: individual differences in susceptibility to suggestion

In two experiments, the authors explored factors that might influence a person's tendency to make source-monitoring errors about autobiographical memories. In the first experiment, undergraduates retrieved a memory from childhood (a) that was known about but not remembered, (b) that was remembered, or (c) for which they were unsure of their memory's source. After writing down the memory, experimental groups listened to a guided visualization tape and answered questions about the event--interventions designed to help them focus on details of their memory. Controls also retrieved and wrote down a memory; however, instead of visualizing the memory, they were instructed to conduct a visual search task. Results indicated that guided visualization led participants to rate known memories closer to remembered events. A second experiment examined individual difference variables that might be related to this know-to-remember shift. Results indicated that extraversion, external locus of control, a memory that conveyed fear, and overall affective content predicted this rating. The applicability of these findings to the psychotherapy process is discussed.     

When is a Concrete Property Basic?

We more or less understand how composition works in the case of objects. We cement bricks together to build a wall. We stir together red paint and yellow paint to get orange paint. In both cases, one way or another, A = B + C. This paper examines composition in the case of concrete natural properties. It explains why property composition is so much less straightforward than object composition. Then it distinguishes strictly basic properties (like the mass of an electron), compositely basic properties (like the mass of a planet), and fully non-basic properties (like the saltiness of blood). It shows how strictly basic properties compose, or result in, compositely basic and fully non-basic properties, which differ from, yet depend for their natures on, the strictly basic properties they result from. It explains the characteristics and differences of these types of properties. It notes that the existence of compositely basic and non-basic properties grounds an argument for the genuine existence of composite properties as well as the composite objects they characterize. Finally, it defends the usefulness of these distinctions by identifying projects they assist, and by applying them both to mark off distinct metaphysical views too often conflated and to correct sundry metaphysical mistakes.     

“LANDSCAPE PLOTTED AND PIECED”: EXPLORING THE CONTOURS OF ENGAGEMENT BETWEEN (NEURO)SCIENCE AND THEOLOGY

This article—the first of a linked set of three outlining the development and practice of a different approach to science/religion dialogue—begins with an overview of some persistent tensions in the field. Then, using a threefold heuristic of encounter, engagement, and expression, it explores the routes taken by James Ashbrook and Andrew Newberg to develop a dialogue between theology and neuroscience, discussing some of the problems associated with these and their implications for attempts to further develop neurotheology. Finally, it proposes a different way of thinking about this enterprise and points toward a new methodology for supporting this endeavor.     

Applying the Interactive Systems Framework to the Dissemination and Adoption of National and State Recommendations for Hypertension

The Centers for Disease Control and Prevention (CDC), Division for Heart Disease and Stroke Prevention (DHDSP), commissioned an Institute of Medicine (IOM) report to identify the highest priority action areas for CDC, state health departments, and other public health partners in their efforts to reduce and control hypertension. To assess the dissemination and adoption of the IOM report recommendations, DHDSP developed an evaluation based on the Interactive Systems Framework for Dissemination and Implementation (ISF). The evaluation incorporates data collection at critical points across 3 years. In this article, we focus on the ISF systems to describe the role of funded state partners and their relationship with CDC in implementing public health recommendations. We describe baseline results for three data collection activities: (1) key informant interviews, (2) a Web‐based survey, and (3) content analysis of state workplans to determine the degree of alignment with IOM recommendations. For example, currently 30 % of surveyed programs are implementing most (or all) of the recommendations in the IOM report, however 76 % intend to change hypertension program priorities based on the recommendations of the IOM report. Qualitative data suggest that there are several facilitators and barriers in implementing public health policy recommendations. DHDSP will use these baseline results to provide additional technical assistance and support to state health departments in their efforts to implement the IOM report's recommendations.

Catholic/Jesuit Values in an Introductory Religious Studies Course

A growing interest in the communication to students of the mission and identity of a higher education institution prompted this study about the presence of Catholic, Jesuit values in the introductory religious studies course at a faith‐based university. To conduct this study a survey instrument was developed, piloted, further refined, and then administered again to about four hundred and fifty students. The study's results showed that the introductory course had a positive effect on the majority of students surveyed, namely, those who had no Catholic schooling or only had a Catholic elementary school education. Statistically significant advances in several areas of knowledge about Catholic teachings endorsed by Catholic bishops and the pope occurred. Although less extensive, knowledge of Jesuit values also advanced in the course.
