Clamped Corticosterone (B) Reveals the Effect of Endogenous B on Both Facilitated Responsivity to Acute Restraint and Metabolic Responses to Chronic Stress

To determine the effects of both corticosterone (B) and chronic stressors on acute ACTH responses to restraint, young male rats were exposed to streptozotocin-induced diabetes, cold (5-7 degreesC) or intracerebroventricular (icv) neuropeptide Y (NPY) for 5 d and then exposed to restraint within 2 h after lights on. Two groups of rats were studied: intact and adrenalectomized replaced with B pellets that maintained plasma B in the normal mean 24-h range of intact rats. In addition to ACTH and B responses to restraint on d 5, body weight, food intake, fat depots, glucose and other hormones were measured to determine the role of stress-induced elevations in B on energy balance. ACTH responses to restraint were normal in intact rats subjected to diabetes or cold. By contrast, there was no ACTH or B response to restraint in NPY-infused intact rats. All 3 groups of chronically stimulated adrenalectomized rats with clamped B had facilitated ACTH responses to restraint compared to their treatment controls. Overall food intake increased in all groups of stressed rats; however, augmented intake occurred only during the light in intact rats and equally in the light and dark in B-clamped rats. White adipose depot weights were decreased by both diabetes and cold and increased by NPY in intact rats; the decreases with cold and increases with NPY were both blunted and changes in fat stores were not significant in adrenalectomized, B-clamped rats. We conclude that: 1. diabetes- and cold-induced facilitation of restraint-induced afferent input to hypothalamic control of the hypothalamo-pituitary-adrenal (HPA) axis is opposed in intact rats by the elevated feedback signal of B secretion; 2. NPY does not induce facilitation of afferent stress pathways; 3. chronic stimulation of the HPA axis induces acute hyperresponsiveness of hypothalamic neurons to restraint provided that the afferent input of this acute stimulus is not prevented by B feedback; 4. stimulus-induced elevations in B secretion result in day-time feeding; 5. insensitivity of both caloric efficiency and white fat stores to chronic stress in adrenalectomized, B-clamped rats results from loss of normally variable B levels.     

Violence restrained: Effects of self-regulation and its depletion on aggression

Aggressive impulses arise from many factors, but they are usually held in check by social norms for self-control. Thus, the proximal cause of aggression is often failure of self-restraint. In five studies, depleted capacity for self-regulation (caused by prior, even irrelevant acts of self-regulation) increased aggressive responding, especially after an insulting provocation. When participants were insulted and their self-regulatory strength was depleted (i.e., after completing previous tasks that required self-regulation), participants were more likely to aggress. When the urge to aggress was relatively weaker (i.e., when participants were not insulted), self-regulatory depletion did not increase aggressive behavior. This effect was moderated by trait self-control: Participants low in trait self-control were particularly likely to express intentions of behaving aggressively in response to provocation, whereas participants high in trait self-control did not express intentions of responding aggressively. Laboratory, autobiographical memory, and hypothetical responses confirmed the pattern.     

The effects of healthy aging on the mnemonic benefit of survival processing

A number of studies have shown that information is remembered better when it is processed for its survival relevance than when it is processed for relevance to other, non-survival-related contexts. Here we conducted three experiments to investigate whether the survival advantage also occurs for healthy older adults. In Experiment 1, older and younger adults rated words for their relevance to a grassland survival or moving scenario and then completed an unexpected free recall test on the words. We replicated the survival advantage in two separate groups of younger adults, one of which was placed under divided-attention conditions, but we did not find a survival advantage in the older adults. We then tested two additional samples of older adults using a between- (Exp. 2) or within- (Exp. 3) subjects design, but still found no evidence of the survival advantage in this age group. These results suggest that, although survival processing is an effective encoding strategy for younger adults, it does not provide the same mnemonic benefit to healthy elders.     

Unique Best Deserver Theory and Arguments From Misclassification

It is a core commitment of Epistemic Two-Dimensionalism (E2D) that an utterance is 1-necessary iff it is a priori. But Jeff Speaks's Argument from Misclassification proves that, on a natural interpretation, E2D assigns necessary 1-intensions to many utterances that speakers deem a posteriori. Given that 1-intensions are meant to formalize a speaker's own understanding of the words she utters, this proof raises serious difficulties for E2D. In response, Elliott, McQueen, and Weber point out that the Argument from Misclassification presupposes a controversial theory of reference-fixation for proper names and argue that E2Dists ought to reject this theory. They discuss three alternatives to the theory that render E2D immune to the Argument from Misclassification. I demonstrate here that each of these alternatives either (i) replicates the faults of the original theory by assigning necessary 1-intensions to a posteriori utterances, or (ii) makes 1-intensions creatures of darkness. I argue that, although the Argument from Misclassification does indeed rely on a controversial theory of reference-fixation, Elliott, McQueen, and Weber have indicated no promising alternative to this theory.     

When Traits Are Behaviors: The Relationship Between Behavioral Responses and Trait-Based Overall Assessment Center Ratings

Federal and state court cases were reviewed to determine the legality of banding. Banding specifies a range of test scores that are considered equivalent for selection purposes, which allows the use of other job-related or diversity factors to select among candidates within a particular band. Although the Supreme Court has not ruled on the legality of banding, state, district, and appellate courts have upheld different types of banding (e.g., fixed, sliding, random) under the 14th Amendment, Title VII of the Civil Rights Act of 1964, and the Civil Rights Act of 1991. However, the case review indicated that banding is less likely to survive legal scrutiny when minority preference is the only factor used to choose among candidates within a band. Implications for organizations using or considering banding are discussed.     

Gratitude and depressive symptoms: The role of positive reframing and positive emotion

Eight studies (N=2,973) tested the theory that gratitude is related to fewer depressive symptoms through positive reframing and positive emotion. Study 1 found a direct path between gratitude and depressive symptoms. Studies 2–5 demonstrated that positive reframing mediated the relationship between gratitude and depressive symptoms. Studies 6–7 showed that positive emotion mediated the relationship between gratitude and depressive symptoms. Study 8 found that positive reframing and positive emotion simultaneously mediated the relationship between gratitude and depressive symptoms. In sum, these eight studies demonstrate that gratitude is related to fewer depressive symptoms, with positive reframing and positive emotion serving as mechanisms that account for this relationship.     

Unpacking Prevention Capacity: An Intersection of Research-to-practice Models and Community-centered Models

Capacity is a complex construct that lacks definitional clarity. Little has been done to define capacity, explicate components of capacity, or explore the development of capacity in prevention. This article represents an attempt to operationalize capacity and distinguish among types and levels of capacity as they relate to dissemination and implementation through the use of a taxonomy of capacity. The development of the taxonomy was informed by the capacity literature from two divergent models in the field: research-to-practice (RTP) models and community-centered (CC) models. While these models differ in perspective and focus, both emphasize the importance of capacity to the dissemination and sustainability of prevention innovations. Based on the review of the literature, the taxonomy differentiates the concepts of capacity among two dimensions: level (individual, organizational, and community levels) and type (general capacity and innovation-specific capacity). The proposed taxonomy can aid in understanding the concept of capacity and developing methods to support the implementation and sustainability of prevention efforts in novel settings.     

Intercultural Study of Personal Space: A Case Study

The study of intercultural differences in personal space attempts to identify factors that could be helpful in guiding people from different cultures to live and work together in international ventures. The objective of this research was to measure interpersonal distance in a cross-cultural environment. Twenty-three participants classified in 4 cultural groups answered an 11-questions interview where the personal distance and orientation between seated interactants were measured. Results showed that Anglo Saxons used the largest zone of personal space, followed by Asians, then Caucasians, and, as expected, Mediterraneans and Latinos used the shortest distance. Where Latinos adopt a face-to-face position, Caucasians tend to orient themselves to the side of the interviewer, which has an impact on interpersonal communication.     

Bridging the Gap Between Prevention Research and Practice: The Interactive Systems Framework for Dissemination and Implementation

If we keep on doing what we have been doing, we are going to keep on getting what we have been getting. Concerns about the gap between science and practice are longstanding. There is a need for new approaches to supplement the existing approaches of research to practice models and the evolving community-centered models for bridging this gap. In this article, we present the Interactive Systems Framework for Dissemination and Implementation (ISF) that uses aspects of research to practice models and of community-centered models. The framework presents three systems: the Prevention Synthesis and Translation System (which distills information about innovations and translates it into user-friendly formats); the Prevention Support System (which provides training, technical assistance or other support to users in the field); and the Prevention Delivery System (which implements innovations in the world of practice). The framework is intended to be used by different types of stakeholders (e.g., funders, practitioners, researchers) who can use it to see prevention not only through the lens of their own needs and perspectives, but also as a way to better understand the needs of other stakeholders and systems. It provides a heuristic for understanding the needs, barriers, and resources of the different systems, as well as a structure for summarizing existing research and for illuminating priority areas for new research and action.
