Alternative Employment Arrangements: A Gender Perspective

In this study we drew on national-level data to investigate the gendered nature of two alternative employment arrangements (independent contractors and temporary agency help), preferences for such arrangements, and the extent to which such arrangements accommodate work/family career quandaries of contemporary workers. Multivariate analyses revealed the perpetuation of gender schema and gendered structures, but this varied by type of alternative employment arrangement. Greater preference for temporary agency employment by married women than by married men derived from women not having to be the primary source of family income, rather than from an effort to balance work and child-rearing responsibilities. There were also gender differences in the tendency of married men and women to be independent contractors; women were less likely to be contractors. However, this alternative employment arrangement offers potential for both men and women to satisfy or challenge other gendered family structures and schema.     

Teaching for adaptive expertise in biomedical engineering ethics

This paper considers an approach to teaching ethics in bioengineering based on the How People Learn (HPL) framework. Curricula based on this framework have been effective in mathematics and science instruction from the kindergarten to the college levels. This framework is well suited to teaching bioengineering ethics because it helps learners develop “adaptive expertise”. Adaptive expertise refers to the ability to use knowledge and experience in a domain to learn in unanticipated situations. It differs from routine expertise, which requires using knowledge appropriately to solve routine problems. Adaptive expertise is an important educational objective for bioengineers because the regulations and knowledge base in the discipline are likely to change significantly over the course of their careers. This study compares the performance of undergraduate bioengineering students who learned about ethics for stem cell research using the HPL method of instruction to the performance of students who learned following a standard lecture sequence. Both groups learned the factual material equally well, but the HPL group was more prepared to act adaptively when presented with a novel situation.     

Individual Concepts in Modal Predicate Logic

The article deals with the interpretation of propositional attitudes in the framework of modal predicate logic. The first part discusses the classical puzzles arising from the interplay between propositional attitudes, quantifiers and the notion of identity. After comparing different reactions to these puzzles it argues in favor of an analysis in which evaluations of de re attitudes may vary relative to the ways of identifying objects used in the context of use. The second part of the article gives this analysis a precise formalization from a model- and proof-theoretic perspective. This material has grown out of Chapters 2 and 4 of my PhD thesis Quantification under Conceptual Covers.     

Neuroscience and learning: lessons from studying the involvement of a region of cerebellar cortex in eyeblink classical conditioning

How the nervous system encodes learning and memory processes has interested researchers for 100 years. Over this span of time, a number of basic neuroscience methods has been developed to explore the relationship between learning and the brain, including brain lesion, stimulation, pharmacology, anatomy, imaging, and recording techniques. In this paper, we summarize how different research approaches can be employed to generate converging data that speak to how structures and systems in the brain are involved in simple associative learning. To accomplish this, we review data regarding the involvement of a particular region of cerebellar cortex (Larsell's lobule HVI) in the widely used paradigm of classical eyeblink conditioning. We also present new data on the role of lobule HVI in eyeblink conditioning generated by combining temporary brain inactivation and single-cell recording methods, an approach that looks promising for further advancing our understanding of relationships between brain and behavior.     

Promoting Alternative Thinking Strategies (PATHS) and Elementary School Aged Children’s Aggression: Results from a Cluster Randomized Trial

This study reports on aggressive outcomes from a cluster randomized trial of the Promoting Alternative Thinking Strategies (PATHS) curriculum. Fourteen elementary schools were randomly assigned to intervention or control condition and third grade students were followed through the fifth grade. Teacher and self-reports of student aggression, conduct problems, delinquency, acting out problems, and social information processing (SIP) variables were collected. Linear change for each of the SIP variables was noted with control students demonstrating increased normative beliefs about aggression, increased aggressive social problem solving, increased hostile attribution bias, and increased aggressive interpersonal negotiation strategies over time while PATHS students remained relatively stable. Teachers reported significant curvilinear change in student aggression, conduct problems, and acting out behavior problems; all favoring PATHS students.     

Evaluating Environmental Change Strategies: Challenges and Solutions

In this introductory article we define environmental change strategies (ECS), summarize the primary challenges associated with evaluating ECS, and provide an overview of the methods researchers have employed to begin to address these challenges. This special issue provides a range of examples, from researchers and practitioners in the field, of different approaches for addressing these challenges. These articles present new methods to understand and test how ECS are implemented and propose methods to evaluate their implementation. The content of the articles covers multiple public health issues, including substance abuse prevention, tobacco control, HIV prevention, and obesity prevention. This special issue is intended to build the evidence base for effective ECS, generate compelling discussion, critical analyses, and spur future research that will help improve the implementation and evaluation of ECS.     

Influences on the Food Choice Behaviors of Adults With Severe Mental Illness

The objective of this research was to gain a deeper understanding of factors influencing the healthiness of food choice behaviors of community-dwelling adults with severe mental illness. Semi-structured interviews were conducted in an outpatient treatment facility with 20 program participants and 10 staff. Grounded theory analysis methods were used. Five dominant themes emerged: food availability, preference for simple food preparation, perceived cost of food, complexity of choice, and relative importance of healthy food choices. The theme of medication effects only emerged from staff interviews. This research can be useful to inform the design of nutrition interventions for this population.     

Darwin's lost theory and its implications for the 21st century

This paper reports the reconstruction of the long ignored “second half” or human level completion for Darwin's theory of evolution. Pursuing the striking contradictions between what has been attributed to Darwin by his neo‐Darwinian and sociobiological heirs and what he actually said, in ignored sections of The Descent of Man and Darwin's long unpublished notebooks it uncovers a three‐level theory of the moral agent that foreshadows the emergence of 20th century social science and the late 20th century rise of the fields of systems science and humanistic psychology. Implications for a joint venture of natural science and social science in the completion of the humanistic and action‐oriented theory of evolution called for by the species‐threatening challenges of the 21st century are considered.
