Social Movements and Party Politics: The Case of the Christian Right

This paper explores the uneasy relationship between social movements and major political parties by considering the case of the Christian Right and the Republican Party in the 1994 elections. We look at four states where the movement was active in party politics and where Republican electoral fortunes varied from failure to success. We found that the degree of intraparty division generated by the Christian Right seemed to hurt Republicans at the polls, but the level of movement activity in itself apparently helped the Republicans. Most factors associated with support for the Christian Right did not help account for electoral outcomes across the states. Instead, the accessibility of the political party nomination processes to the movement best accounted for the election results: greater party openness was associated with poor results and more limited access with greater success for the GOP.     

Moral injury,coherence, and spiritual repair

In the PTSD literature, moral injury represents dissonance between a person’s beliefs about how they and the world should function, and the trauma event(s) they experienced. Given the association of moral injury with the assumptive world, it is not surprising the concept is closely intertwined with spiritual concerns. This paper reports on a spiritually integrated group intervention designed to help veterans with PTSD in the process of moral and spiritual repair. Qualitative findings are shared from interviews conducted with 18 participants who completed the intervention. Themes are centred around participants’ overall response to their experience in the group; where they are at regarding feelings such as guilt, shame, anger, trust, sense of betrayal, and desire for forgiveness; changes in religious/spiritual beliefs and practices and the experience of moral injury; and if they now find meaning in the trauma. The findings support the need for additional treatment options that address the moral and spiritual aspects of trauma.     

Typicality effects in contingency-shaped generalized equivalence classes

Two experiments were conducted using match-to-sample methodologies in an effort to model lexical classes, which include both arbitrary and perceptual relations between class members. Training in both experiments used a one-to-many mapping procedure with nonsense syllables as samples and eight sets of abstract stimuli as comparisons. These abstract stimuli differed along a number of dimensions, four of which were critical to the experimenter-defined class membership. Stimuli in some comparison sets included only one of the class-defining features, but stimuli in other sets included two, three, or all four of the critical features. After mastery of the baseline training, three types of probe tests were conducted: symmetry, transitivity/equivalence, and novel probe tests in which the training nonsense syllables served as samples, and comparisons were novel abstract stimuli that included one or more of the class-defining features. Symmetry and transitivity/equivalence probe tests showed that the stimuli used in training became members of equivalence classes. The novel stimuli also became class members on the basis of inclusion of any of the critical features. Thus these probe tests revealed the formation of open-ended generalized equivalence classes. In addition, typicality effects were observed such that comparison sets with more critical features were learned with fewer errors, responded to more rapidly, and judged to be better exemplars of the class. Contingency-shaped stimulus classes established through a match-to-sample procedure thus show several important behavioral similarities to natural lexical categories.     

Functional equivalence classes in rats: Repeated olfactory discrimination reversals and delayed stimulus probes

The simultaneous matching-to-sample procedures that are widely used to study stimulus equivalence in human participants have generally been unsuccessful in animals. However, functional equivalence classes have been demonstrated in pigeons and sea lions using a concurrent repeated reversal discrimination procedure. In this procedure, responding to one set of stimuli is reinforced but responding to a different set is not and the set associated with reinforcement is changed with multiple reversals during the experiment. The experiments reported here were designed to assess whether functional equivalence classes could be demonstrated in rats using similar techniques. Rats were initially trained with two sets of olfactory stimuli (six odors/set). Following many reversals, probe reversal sessions were conducted in which rats were exposed to a subset of the members of each set and, later in the session, the withheld stimuli were introduced. Responding to these delayed probe trials in accord with the reversed contingencies constituted transfer of function. There was some evidence of transfer in Experiment 1, but the effects were relatively weak and variable. Experiment 2 introduced procedural changes and found strong evidence of transfer of function consistent with the formation of functional equivalence classes. These procedures offer a promising strategy to study symbolic behavior in rodents.     

Effects of dizocilpine (MK801) on olfactory span in rats

NMDA receptor antagonists interfere with learning and memory in some tasks, but not others. Some recent accounts have suggested that tasks placing demands on working memory are those most likely to be affected, and the present study tested this hypothesis. The purpose of the study was to adapt a recently developed procedure designed to test working memory capacity, the olfactory memory span task, for use in behavioral pharmacology and to then determine the effects of the NMDA receptor antagonist, dizocilpine (MK801) on performance in this task. Rats were trained in a non-match-to-sample procedure under conditions in which they had to remember an increasing number of olfactory stimuli as the session progressed. Simple olfactory discrimination trials were interspersed to provide a performance control. Effects of dizocilpine (.03, .10, .17, .3mg/kg) were determined after stable performances were obtained. Rats were able to sustain stable performances on both the span and simple discrimination tasks with average spans of about 10 items. Accuracy declined as the number of stimuli to remember increased, and dizocilpine impaired accuracy in a dose-dependent and memory-load dependent fashion. The finding that the effects of dizocilpine interacted with the number of stimuli to remember is generally consistent with hypotheses linking NMDA receptors and working memory processes.     

Using the Interactive Systems Framework to Support a Quality Improvement Approach to Dissemination of Evidence-Based Strategies to Promote Early Detection of Breast Cancer: Planning a Comprehensive Dynamic Trial

Dissemination efforts must optimize interventions for new settings and populations. As such, dissemination research should incorporate principles of quality improvement. Comprehensive Dynamic Trial (CDT) designs examine how information gained during dissemination may be used to modify interventions and improve performance. Although CDT may offer distinct advantages over static designs, organizing the many necessary roles and activities is a significant challenge. In this article, we discuss use of the Interactive Systems Framework for Dissemination and Implementation to systematically implement a CDT. Specifically, we describe “Bronx ACCESS”, a program designed to disseminate evidence‐based strategies to promote adherence to mammography guidelines. In Bronx ACCESS, the Intervention Delivery System will elicit information needed to adapt strategies to specific settings and circumstances. The Intervention Synthesis and Translation System will use this information to test changes to strategies through “embedded experiments”. The Intervention Support System will build local capacities found to be necessary for intervention institutionalization. Simulation modeling will be used to integrate findings across systems. Results will inform on‐going policy debate about interventions needed to promote population‐level screening. More generally, this project is intended to advance understanding of research paradigms necessary to study dissemination.
