论水平扭剪应力场对大裂缝系统的控制

本文根据地质力学和岩体结构力学原理，探讨水平扭剪应力场在大裂缝系统形成、转化和分布中的重要控制作用及其物理模型．文中认为，大裂缝系统是较大的直压型裂缝网络与扭剪型裂缝网络叠加的产物，主要分布在较强的水平扭剪应力和术平直压应力复合作用的区块；水平扭剪应力场是改造和控制大裂缝网络结构异向性的最重要因素。这为研究和勘探较大的隐伏裂缝系统，提供了新的成藏模式和理论依据。     

Legal Marriage,Unequal Recognition,and Mental Health Among Same‐Sex Couples

The authors examined whether the perception of unequal relationship recognition ‐ a novel couple‐level minority stressor ‐ has negative consequences for mental health among same‐sex couples. Data were analyzed from a dyadic study of 100 same‐sex couples (200 individuals) in the United States. Being in a legal marriage was associated with lower perceived unequal recognition and better mental health; being in a registered domestic partnership or civil union—but not also legally married—was associated with greater perceived unequal recognition and worse mental health. Actor partner interdependence models tested associations between legal relationship status, unequal relationship recognition, and mental health (nonspecific psychological distress, depressive symptomatology, and problematic drinking), net controls (age, gender, race and ethnicity, education, and income). Unequal recognition was consistently associated with worse mental health, independent of legal relationship status. Legal changes affecting relationship recognition should not be seen as simple remedies for addressing the mental health effects of institutionalized discrimination.     

A Mixed-Methods Inquiry Into Trans* Environmental Microaggressions on College Campuses: Experiences and Outcomes

ABSTRACT

The experiences, including with environmental microaggressions, and well-being of trans* collegians remain an under-researched topic. In this mixed-methods study of a survey sample of 152 trans* collegians, multivariable regression findings suggest that the frequency of experiencing select trans* environmental microaggressions (e.g., not having access to comfortable bathrooms as a trans* person) are associated with increased risk for poorer academic outcomes (e.g., developmental challenges) but are not associated with mental health outcomes. Furthermore, interviews with 18 trans* collegians suggest that students face several systemic microaggressions, including difficulties advancing trans* inclusion. Various reactions, including paths of resistance, were identified. Implications are discussed.     

“重陆轻海”与“通洋裕国”之海洋观刍议

明清两朝正处于世界性海洋历史发展的"千古变局"时代,但统治者沿袭传统模式,在立国思想上"重农抑商"、"重陆轻海",在国防战略上以"禁海"代替海防,禁海迁界、"守土防御",反映其海洋观念的淡薄;而东南沿海地方官员,尤其郑成功"通洋裕国"思想的提出和实践,显露出"以商立国",向海洋空间发展的意涵;传统时代"重陆轻海"与"通洋裕国"所反映的海洋观念,对国家民族发展的影响在某种程度上可以忽略不计,但大航海时代,海洋作为人类的第二生存空间影响到世界历史走向和发展格局时,"重陆轻海"观念所带来的深层影响会因此而改变国家和民族的命运。     

Combat Social Work During the Surge in Iraq

The military has long recognized the short-term psychiatric effects of war upon soldiers, a significant factor for combat operational readiness and strength (NATO, 2008). Currently referred to as combat stress reaction or combat operational stress reaction (COSR), the condition has debilitating, immediate effects as well as long-term consequences for soldiers and military units. For the wars in Iraq and Afghanistan, commanders expected psychiatric casualties rates equaling physical ones, stemming from the intensity and duration of these conflicts, nonlinear nature of the battlefields, unit morale, and soldier experiences and preparedness. For these recent wars, the concept of behavioral health, combat stress, and its military importance has dramatically changed, as have the protocols dictating the delivery of preventive and restorative combat behavioral health care. This article outlines the conceptual foundation of modern combat stress control, protocols, and the efforts of one social worker–led combat stress prevention team, forward deployed to a small base in a volatile area of Baghdad during the height of the surge in 2006–2007.     

Randomized controlled trial of the Resilience and Coping Intervention (RCI) with undergraduate university students

Objective: The purpose of this pilot study was to evaluate the Resilience and Coping Intervention (RCI) with college students. Participants: College students (aged 18–23) from a large Midwest US university who volunteered for a randomized controlled trial during the 2015 spring semester. Methods: College students were randomly assigned to an intervention (n = 64) or a control (n = 65) group. Intervention participants received three 45-minute RCI sessions over subsequent weeks. All participants completed pre- and post-intervention assessments at the beginning of Week 1 and end of Week 3. Student resilience, coping, hope, stress, depression, and anxiety were assessed. Results. RCI participants reported significantly more hope and less stress and depression from Week 1 to Week 3 compared with control participants. Results for resilience also approached statistical significance. Effect sizes were small to moderate. Conclusions: This study found preliminary evidence that RCI is an effective resilience intervention for use with college students.     

Statistical modeling for Bayesian extrapolation of adult clinical trial information in pediatric drug evaluation

Children represent a large underserved population of “therapeutic orphans,” as an estimated 80% of children are treated off‐label. However, pediatric drug development often faces substantial challenges, including economic, logistical, technical, and ethical barriers, among others. Among many efforts trying to remove these barriers, increased recent attention has been paid to extrapolation; that is, the leveraging of available data from adults or older age groups to draw conclusions for the pediatric population. The Bayesian statistical paradigm is natural in this setting, as it permits the combining (or “borrowing”) of information across disparate sources, such as the adult and pediatric data. In this paper, authored by the pediatric subteam of the Drug Information Association Bayesian Scientific Working Group and Adaptive Design Working Group, we develop, illustrate, and provide suggestions on Bayesian statistical methods that could be used to design improved pediatric development programs that use all available information in the most efficient manner. A variety of relevant Bayesian approaches are described, several of which are illustrated through 2 case studies: extrapolating adult efficacy data to expand the labeling for Remicade to include pediatric ulcerative colitis and extrapolating adult exposure‐response information for antiepileptic drugs to pediatrics.

Three Approaches to Understanding Self-Help Groups

With the increasing importance of self-help groups, professionals need to augment their understanding of how groups work in order to help clients make effective use of them. Three conceptual frameworks-social networks, social learning and cognitive theory-explain the basic psychosocial processes of self-help groups. Practice implications indicate how clients can benefit from self-help groups and suggest how professionals might enable their clients to realize the full benefits of participation in them.     

Psychologically and biochemically assessed stress in a follow-up study of long-term unemployed

Abstract

It has been suggested that psychological stress is one of the reasons for the high morbidity among unemployed people in Western countries. The same may apply to the well-documented high mortality. It would be expected that increased levels of biological stress would be found in these people. In the present study a sample of 310 long-term unemployed people from Norway was followed for 2 years. Psychologcal stress was assessed by medical examination and by the psychometric tests GHQ-28 and HSCL-30, the latter compared with a reference population of employed people. Serum levels of cortisol, prolactin and testosterone, together with immunoglobulins IgA, IgG and IgM, were compared with working controls. The unemployed had a high level of psychological distress at the first examination, the sanie for men and women. At the 2-year follow up distress was reduced by re-employment. This fits the ‘causation hypothesis' which explains the high distress level as caused by unemployment. The other direction of causation, ‘the selection hypothesis', assuming that distressed persons have an increased chance of continuous unemployment, was also confirmed in the present study. As for biological stress, significant differences were not found between the unemployment, the re-employed and the working controls.
