What Turns on Hinges?

Being unable - when we surrender ourselves to philosophical thought - to help saying such-and-such; being irresistibly inclined to say it - does not mean being forced into an assumption …     

Introduction to the special section on dissemination: dissemination research and research dissemination: how can we close the gap?

One of the greatest challenges facing health promotion and disease prevention is translating research findings into evidence-based public health and clinical practices that are actively disseminated and widely adopted. Despite the tremendous strides made in developing effective disease prevention and control programs, there has been little study of effective dissemination of evidence-based programs to and adoption by community, public health, and clinical practice settings. This special section provides a venue in which to highlight exemplary dissemination research efforts while also identifying limitations in research to date and framing important future research questions. This issue establishes a resource for investigators interested in dissemination research, with relevance to health psychology. In this sense, it can serve as a benchmark by which to examine subsequent progress. The 6 articles reflect the state of the science in dissemination research for the promotion and adoption of health behavior change interventions.     

The Interpersonal Theory of Suicide Applied to Male Prisoners

The interpersonal theory of suicide proposes that severe suicide ideation is caused by the combination of thwarted belongingness (TB) and perceived burdensomeness (PB), yet few studies have actually examined their interaction. Further, no studies have examined this proposal in male prisoners, a particularly at‐risk group. To address this gap, the current study surveyed 399 male prisoners. TB and PB interacted to predict suicide ideation while controlling for depression and hopelessness. High levels of both TB and PB were associated with more severe suicide ideation. The interpersonal theory may aid in the detection, prevention, and treatment of suicide risk in prisoners.     

Global Interaction in Classical Mechanics

In this paper, an example is presented for a dynamic system analysable in the framework of the mechanics of rigid bodies. Interest in the model lies in three fundamental features. First, it leads to a paradox in classical mechanics which does not seem to be explainable with the conceptual resources currently available. Second, it is possible to find a solution to it by extending in a natural way the idea of global interaction in the context of what is called interaction by impenetrability. Third, the solution presented throws light on a problem posed and discussed in the recent literature in connection with the mass conservation principle.
