The relationship of trauma exposure to sex offending behavior among male juvenile offenders

The most common type of adult and juvenile sex offender treatment utilizes a Relapse Prevention (RP) model. In RP clients learn about their offense cycle with an emphasis on recognizing high-risk situations and negative emotional states that can be precursors or triggers to offending behavior. This study identifies ways that traumatic experiences and trauma-associated feelings can be offense triggers for juvenile sex offenders. Researchers interviewed the treating clinicians of 40 male juvenile sex offenders who received at least six months of RP sex offender treatment. Results showed that 95% of the youths had experienced a Post Traumatic Stress Disorder (PTSD) Criterion A traumatic event and that 65% met criteria for PTSD based on clinician judgments. Overall, clinicians identified prior trauma exposure as being related to the offense triggers in 85% of offenders. Specifically, the following trauma-related feelings were identified as offense triggers: intense fear in 37.5% of sex offenders, helplessness in 55%, and horror in 20%. Implications for sex offender treatment programs are discussed.     

Many a slip between cup and lip. Process evaluation of a program to promote and support evidence-based public health practice

The main aims of this study are to document whether an intervention for promoting evidence-based public health practice had been delivered as intended and to explore the reasons for its lack of impact. Process data from the implementation of the program and data from interviews with 40 public health physicians are analyzed. Although they expressed satisfaction with the service, the doctors experienced the program as rather irrelevant for their daily work. They did not perceive that they dealt with many issues relevant for the use of research information, and if they did, referring to research would not make any difference to the way others perceived their advice. There is a need to develop more overlying strategies for integrating evidence into decision making than addressing the individual level.     

Role of workplace safety: a revisit of the relationship between job satisfaction and employment status

This study evaluated the relationship between employment status (i.e., part- and full-time) and job satisfaction, with the focus on the moderating roles of perceived injury risk and injury incidence. The results found that the level of job satisfaction for full-time workers was about the same regardless of the level of injury risk they perceived. In contrast, job satisfaction of part-time workers was significantly higher when they perceived low injury risk rather than high injury risk. The findings also supported the potential adverse impact of injury incidence and injury risk on job satisfaction for both part- and full-time workers. This study highlighted the importance of understanding both workplace safety and job satisfaction when attempting to understand the differences between part-time and full-time workers.     

The role of natural recovery in alcoholism and pathological gambling

While most pathological gamblers, like most alcohol abusers, recover on their own, it seems likely that they are at greater risk for relapse than those who have been through successful treatment. Accordingly, a substantial increase in treatment resources for pathological gamblers, along with greater efforts to establish the effectiveness of these treatments, ought to receive national priority. If the data on alcohol-abusing self-changers are generalizable to self-changing pathological gamblers, the prognosis for gamblers who stop gambling all together is better than for those who aspire to controlled or nonproblem gambling. While pathological gamblers with comorbid substance abuse are more difficult to treat than those without it, the impact of comorbid substance abuse on the decision by pathological gamblers to change has not yet been explored, although it should be. Similarly, the impact of other Axis I pathology on pathological gambling self-change, especially depression and anxiety, should be thoroughly explored. The most pressing problem in this field appears to be definitional. As a consequence, until consensus is reached on a reliable, valid, and useful classification scheme for pathological gambling, both research and clinical efforts will continue to suffer.     

Mouse and human cells versus oxygen

Mice and humans are at opposite ends of the mammalian spectrum of longevity. A major question in biology is whether this difference can be accounted for by differences in the properties of cells from these two species. A new publication from Judith Campisi's lab reports that human cells in culture are more resistant than mouse cells to the damaging effects of 20% oxygen. The greater burden of DNA damage sustained by mouse cells causes them to rapidly enter a phase of culture in which most cells enter permanent growth arrest (replicative senescence). However, some mouse cells usually escape from senescence and then grow into an immortal cell line. This never happens in human fibroblast cell cultures. Human cells also eventually enter replicative senescence in culture, but this phenomenon is caused by shortening of telomeres and not by DNA damage of the type responsible for mouse cell senescence. Human fibroblasts never spontaneously escape from senescence. This Perspective reviews differences between mouse and human cells that could account for these differences in behavior. Some evidence indicates that human cells are generally more resistant than mouse cells to oxidative damage to DNA, but more needs to be done to confirm this finding and to understand the underlying mechanisms. Whether or not there are differences in the amount of DNA damage caused by oxygen or in the early phase of repair, there may be important differences in the later consequences of DNA damage. Mouse cells appear to be able to continue to divide with DNA damage that has not been repaired or has been misrepaired, and becomes fixed in the form of chromosomal abnormalities. The checkpoints that cause cells to stop dividing when chromosomes develop abnormalities (aberrations or shortened telomeres) appear to operate more efficiently in human cells. Much more work is needed to understand the basis for these differences and the implications for aging and cancer.     

Who Reaps the Benefits,Who Bears the Risks? Comparative Optimism,Comparative Utility,and Regulatory Preferences for Mobile Phone Technology

Although the issue of risk target (e.g., self, others, children) is widely acknowledged in risk perception research, its importance appears underappreciated. To date, most research has been satisfied with demonstrating comparative optimism, i.e., lower perceived risk for the self than others, and exploring its moderators, such as perceived controllability and personal exposure. Much less research has investigated how the issue of target may affect benefit perceptions or key outcomes such as stated preferences for hazard regulation. The current research investigated these issues using data from a public survey of attitudes toward mobile phone technology (N= 1,320). First, results demonstrated comparative optimism for this hazard, and also found moderating effects of both controllability and personal exposure. Second, there was evidence of comparative utility, i.e., users believed that the benefits from mobile phone technology are greater for the self than others. Third, and most important for policy, preferences for handset regulation were best predicted by perceptions of the risks to others but perceived benefits for the self. Results suggest a closer awareness of target can improve prediction of stated preferences for hazard regulation and that it would be profitable for future research to pay more attention to the issue of target for both risk and benefit perceptions.     

伦理经济原理与市场经济伦理

伦理学和经济学仿佛是互有敌意的兄弟。说它们是兄弟,因为它们都是关于人的行动和决策的理论,都关心行动和决策的合理性和正确性。说它们互有敌意,因为它们的规范性内容似乎是互相矛盾的,伦理学追求至善,而经济学追求效率,至善的东西未必有效率,有效率的东西未必至善;追求至善的好心人未必总是得到好报,追求效率的坏人未必总是得到恶报。怎样解决两者之间的这种矛盾,伦理经济提出了若干基本原理,其中最重要的有:善的三重性(道德、效果和效率)原理;伦理经济的双重性(经济和伦理性质)原理;作为伦理学经济的伦理经济原理(如道德利益相容性原理、普遍利益权重原理等);作为市场经济的伦理预设的伦理经济原理(如契约第三方原理、双重效应原理、超动机原理等)。     

Forecasting the market for ships

Product development and market penetration strategy rely on dependable forecasts. Market segmentation is necessary for finding profitable niches. The paper describes macro- forecasts in the maritime sector divided by nine ship types. Balance between supply and demand is calculated with dynamic models. Demand for transportation depends on the development of world trade. Supply of transportation capacity depends on present fleet size, future contracting, scrapping and productivity.
