Starting with the premise that research questions emanating from the fields of psychoneuroimmunology and behavioral medicine may provide critical information for understanding and treating acquired immune deficiency syndrome (AIDS), we provide brief backgrounds on psychoneuroimmunology and on AIDS. Previously, Solomon had generated 25 hypotheses based on the thesis that the immune and central nervous systems are intimately linked. Eight hypotheses from his list are presented as particularly relevant to AIDS. From these hypotheses, we derived a set of 12 new questions to be addressed in research on AIDS. Evidence and illustrations from studies in the literature, from our own research on psychoimmunologic relationships and psychosocial factors related to outcome, and from clinical examples is discussed for each question. Finally, suggestions are offered to address some of the problems in conducting psychoneurologic research. 相似文献

This study explores connections between inward-directed violence and outward-directed violence using data from the Reach for Health sample, which was originally recruited in the 1990s from three middle schools in economically distressed, predominantly African American neighborhoods of New York City. Now in their thirties, participants (N = 595) completed surveys assessing current suicidal thoughts and behaviors as well as other violence involvements, including intimate partner violence victimization and perpetration. About 10% of males and females reported any suicidal ideation or attempt in the past 12 months. In logistic regression analyses adjusting for sociodemographics, prior reports of feeling blue in middle school (OR: 1.12, CI: 1.02–4.39) and young adult suicidality (OR: 2.54, CI: 1.30–4.95) are significantly related to later suicidality. So are concurrent aggressive behaviors, including reports of physical fighting outside the home (OR: 2.70, CI: 1.29–5.67) and IPV perpetration (OR: 2.09, CI: 1.11–3.94). Neither IPV victimization nor witnessing neighborhood violence is correlated. Findings shed light on the persistence of suicidality in the lives of those who come of age, and often remain, in communities with high levels of poverty, and confirm linkages of suicidality with externally directed aggression. Life-stage interventions are needed to counter the interwoven causes and consequences of multiple forms of violence. 相似文献

Two studies were conducted to develop and examine internal consistencies and validate the Abbreviated Multidimensional Acculturation Scale. Study 1 participants were 156 Latino/Latina college students. Findings indicated good internal reliabilities for all 3 subscales. Adequate concurrent validity was established with length of residence in the United States. The scale also showed adequate convergent and discriminant validity. Study 2 participants were 90 Latino/Latina community members. The subscales were also reliable and showed adequate concurrent validity with length of residence in the United States. Convergent and discriminant validity were also adequate. Construct validity was further demonstrated through factorial analyses of the combined samples (N = 246). Three separate factors emerged: cultural identity, language competence, and cultural competence. 相似文献

In subterranean species where excavation is energetically expensive, efficient spatial navigation is vital to reducing the costs of locating important resources such as food and mates. While spatial navigational ability is positively correlated with sociality in subterranean mammals, we have a less clear understanding of the role of habitat complexity on navigational ability. We tested spatial navigational ability and memory in 12-18-month captive Natal mole-rats (Cryptomys hottentotus natalensis) maintained in a simple environment with no environmental enrichment and newly captured wild individuals from natural, complex burrow systems. In maze trials, mole-rats captured freshly from the wild made significantly fewer navigational errors, were more likely to successfully navigate the maze, travelled shorter distances and as a consequence, completed the maze in less time. Male mole-rats from both experimental treatments were more likely to complete the maze than females. Memory retention of the maze was tested on day two, seven, 30 and 60, respectively. The results were variable, although both groups showed a significant memory retention 60?days after testing. Our results highlight the potential importance of the environment (microhabitat complexity) on spatial cognitive performance in mole-rats. 相似文献

I examine the role of inference from experiment in theory building. What are the options open to the scientific community when faced with an experimental result that appears to be in conflict with accepted theory? I distinguish, in Laudan’s (1977), Nickels’s (1981), and Franklin’s (1993) sense, between the context of pursuit and the context of justification of a scientific theory. Making this distinction allows for a productive middle position between epistemic realism and constructivism. The decision to pursue a new or a revised theory in response to the new evidence may not be fully rationally determined. Nonetheless, it is possible to distinguish the question of whether there is reason to pursue a theory from the question of whether that theory, once it has been pursued over time, solves a problem of interest to science. I argue that, in this context, there is a solid way to distinguish between the contexts of pursuit and of justification, on the basis of a theory’s evidential support and problem-solving ability. 相似文献
