Three Poems

Within Southern Appalachia there are distinct, historic patterns of exploitation. These patterns have helped to give shape to certain cultural tendencies that are strikingly similar to the clinical manifestations of groups who have experienced traumatic stress. Once normative adaptations to the well documented crises that come with unemployment, over the generations they became ingrained in the culture. The resulting cultural traits-an enduring sense of resignation, deep depression, and disrupted relationships represent the presence of a culturally transmitted traumatic stress syndrome that is induced by exploitation.     

A general causal model to guide alcohol, tobacco, and illicit drug prevention: assessing the research evidence

The problems associated with the use of alcohol, tobacco, and other drugs (ATOD) extract a significant health, social, and economic toll on American society. While the field of substance abuse prevention has made great strides during the past decade, two major challenges remain. First, the field has been disorganized and fragmented with respect to its research and prevention practices; that is, there are often separate ATOD prevention "specialists." Second, both the prevention researchers who test the efficacy of specific prevention strategies and the practitioners who implement prevention efforts often lack an overall perspective to guide strategy selection. To address these limitations, we present an ATOD causal model that seeks to identify those variables (Domains) that are theoretically salient and empirically connected across alcohol, tobacco, and illicit drugs. For the researcher, the model demonstrates important commonalities, as well as gaps, in the literature. For the practitioner, the model is a means to recognize both the complexity of the community system that produces ATOD problems and the multiple intervention points that are possible within this system. Researchers and practitioners are thus challenged to work synergistically to find effective and cost-effective approaches to change or reduce ATOD use and associated problems.     

Children''s Exposure to Arsenic from CCA-Treated Wooden Decks and Playground Structures

CCA-treated wood is widely used in the fabrication of outdoor decks and playground equipment. Because arsenic can be removed from the surface of CCA-treated wood both by physical contact and by leaching, it is important to determine whether children who play on such structures may ingest arsenic in quantities sufficient to be of public health concern. Based on a review of existing studies, it is estimated that arsenic doses in amounts of tens of micrograms per day may be incurred by children having realistic levels of exposure to CCA-treated decks and playground structures. The most important exposure pathway appears to be oral ingestion of arsenic that is first dislodged from the wood by direct hand contact, then transferred to the mouth by children's hand-to-mouth activity. The next most important pathway appears to be dermal absorption of arsenic, while ingestion of soil that has become contaminated by leaching from CCA-treated structures appears to be of lesser importance, except possibly in the case of children with pica. Considerable uncertainty, however, is associated with quantitative estimates of children's arsenic exposure from CCA-treated wood. Priorities for refining estimates of arsenic dose include detailed studies of the hand-to-mouth transfer of arsenic, studies of the dermal and gastrointestinal absorption of dislodgeable arsenic, and studies in which doses of arsenic to children playing in contact with CCA-treated wood are directly determined by measurement of arsenic in their urine, hair, and nails.     

Mnemonic Institutions and Residential Clustering: Jewish Residential Patterns in Toronto

In this paper, we envisage how the sociohistorical experiences of groups are related to their residential patterns. We posit that the residential clustering of a group can be strongly related to the group's mnemonic institutions, which are organizational symbols of collective identity that link the present to the past. We present the case of Jewish residential clustering patterns in Toronto to demonstrate our arguments. We employ 2001 Canadian Census tract‐level data to show Jewish residential clustering patterns in relation to the presence of a synagogue or Jewish community center, the mnemonic institutions of Jews.     

Back to Stir It Up: Erectile Dysfunction in an Evolutionary,Developmental, and Clinical Perspective

In this review, we analyze erectile dysfunction (ED) in the context of sexual selection. We highlight that ED is a specific human male characteristic linked to the loss of the baculum or penile bone and results from a range of physical and psychological factors. We discuss evolutionary interpretations that consider dysfunctional penile erection as an honest signal of a low-quality male. We further emphasize the importance of considering psychosocial context and early attachment dynamics for understanding the etiology of some types of ED. Finally, we suggest that the integration of developmental factors for understanding the emergence of this sexual disorder is instrumental for the calibration of more effective therapies.     

欧盟电子电气设备废弃物指令的生产者影响分析

在欧盟,荷兰、比利时和瑞典等国家的WEEE回收体系已经建立并运行了多年。根据这些国家的经验,欧盟制定了《关于电子电气设备废弃物(WEEE)指令》。生产者在WEEE指令中责任可分解为经济责任、信息责任和逆向物流责任。本文围绕WEEE指令中针对生产者经营的问题,提出相应的修改建议。
