Reciprocal pathways between intimate partner violence and sleep in men and women

Toward explicating associations and directionality of effects between relationship processes and a fundamental facet of health, we examined cross-sectional and longitudinal associations between the perpetration of intimate partner violence (IPV) and men and women's sleep. During two assessments, a diverse community sample of couples reported on their perpetrated acts of psychological and physical IPV and their sleep quality. Cross-sectional associations between IPV and sleep were evident for both partners, in particular between psychological IPV and sleep. A dyadic path analysis controlling for the autoregressive effects and within-time correlations revealed longitudinal links between men's perpetration of IPV and their sleep quality. Even though high levels of stability in all IPV and sleep measures were observed over time, results indicated that sleep problems predicted increases in the perpetration of psychological IPV over time for both men and women. Cross-partner effects emerged for men, revealing that men's sleep problems were strongly affected by their partner's earlier perpetration of IPV and sleep difficulties. Findings illustrate the significance of contemporaneous, dyadic assessments of relationship processes and sleep for a better understanding of both facets of adaptation, and have implications for those wishing to understand the etiology and consequences of the perpetration of IPV for both men and women.     

Where gamma fails

A major question for the relevant logics has been, “Under what conditions is Ackermann's ruleγ from -A ∨B andA to inferB, admissible for one of these logics?” For a large number of logics and theories, the question has led to an affirmative answer to theγ problem itself, so that such an answer has almost come to be expected for relevant logics worth taking seriously. We exhibit here, however, another large and interesting class of logics-roughly, the Boolean extensions of theW — free relevant logics (and, precisely, the well-behaved subsystems of the 4-valued logicBN4) — for which γ fails.     

Where Meaning is

Abstract

In an attempt to find some new ways of tackling old problems about meaning, I explore some possible models in which meaning may be conceptually situated. I take a close look at a traditional realist conception of meaning and give some reasons as to why we may have more room to move within this than is immediately apparent. Alternative frameworks are explored along the way.

The approach of thus situating meaning is an ontological one, but it is also an epistemological, as well as a hermeneutical one; in that the models put forward illuminate central issues and offer potential solutions to outstanding puzzles ranging across (at least) all of these broad realms of enquiry. Such solutions give a set of initial conceptualizations of the potential role meaning can play across broader frameworks of enquiry. As such they offer fresh inroads into otherwise deadlocked debates over the nature and place of meaning across philosophical enquiry in general.     

Feminist Bioethics: Where We've Been, Where We's Going

The primary contribution of feminism to bioethics is to note how imbalances of power in the sex-gender system play themselves out in medical practice and in the theory surrounding that practice. I trace the ten-year history of feminist approaches to bioethics, arguing that while feminists have usefully critiqued medicine's biases in favor of men, they have unmasked sexism primarily in the arena of women's reproductive health, leaving other areas of health care sorely in need of feminist scrutiny. I note as well that feminist bioethicists have contributed very little to bioethical theory. In the second part of the paper I suggest two future directions for feminist bioethics. The first is to expand its critique of gender bias beyond reproductive medicine, devoting attention to the same issues raised by advances in biomedical technology as are taken up by mainstream bioethicists. The second is to develop bioethical theory that is more responsive than are mainstream moral theories to the social practices that subordinate women and minority groups.

Comments on Where the Creativity Research Has Been and Where Is It Going

This Commentary examines where the creativity research has been and where it is going. They key points include evolving definitions of creativity, interdisciplinarity in the creativity research, divergent thinking as a reliable index of creative potential, improvements in testing, the impact of technology, the inclusion of political, moral, and everyday creativity in the research, the use of semantic networks and conceptual maps, the creative economy, and the need to extricate personal creativity from social recognition.     

A Dialectic on Validity: Where We Have Been and Where We Are Going

It has been suggested that the primary issue in considerations of validity today is the discrepancy between currently accepted theory and the practice of validation. The reason for this discrepancy may be that although considerable discussion has taken place in educational measurement and psychometrics regarding changes in our conceptions of validity, that has not been the case more generally in the social and behavioral sciences. A dialectic on the current status of validity theory for social and behavioral scientists is presented to help bridge this gap.
