With the advance of biotechnology, biological information, rather than biological materials, is increasingly the object of principal security concern. We argue that both in theory and in practice, existing security approaches in biology are poorly suited to manage hazardous biological information, and use the cases of Mousepox, H5N1 gain of function, and Botulinum toxin H to highlight these ongoing challenges. We suggest that mitigation of these hazards can be improved if one can: (1) anticipate hazard potential before scientific work is performed; (2) consider how much the new information would likely help both good and bad actors; and (3) aim to disclose information in the manner that maximally disadvantages bad actors versus good ones.  相似文献

Young adults commonly exit from and return to the parental home, yet few studies have examined the motivation behind these exits and returns using a life course framework. Using data from the National Longitudinal Survey of Youth 1997, the authors examined associations between mental health problems and economic characteristics and exits from (n = 8,162) and returns to (n = 6,530) the parental home during the transition to adulthood. The average age of the respondents was 24 years. The authors found evidence that mental health and economic characteristics were related to home leaving and returning. Emotional distress was associated with earlier exits from and returns to the parental home; alcohol problems were associated with earlier returns to the parental home. The findings regarding economic resources were unexpectedly mixed. Greater economic resources were linked to delayed exits from and earlier returns to the parental home. The implications of these findings for young adults are discussed.  相似文献

This longitudinal dyadic clinical process study used coded data from eleven couples to determine the influence of therapist warmth behaviors on couples' warmth behaviors over time in therapy. A mixed effects model was used to examine within‐ and between‐individual variability. Men and women were modeled separately. A series of two‐level multilevel models of change were examined, where Time is Level 1 and Individual is Level 2. Findings were mixed. There was no significant relationship between therapist warmth toward wife and wife warmth toward husband; however, there was a significant relationship between therapist warmth toward husband and husband warmth toward wife. Findings demonstrated that 62.9% of the variance in husband warmth toward wife was accounted for by therapist warmth to husband across time in therapy. Specifically, therapist warmth toward husband was significantly and positively related to husband warmth toward wife over time in therapy. Clinical implications and directions for future research are discussed.  相似文献

This article complements existing studies on the incumbency effects of conditional cash transfers (CCTs) by analysing the principal mechanisms by which Mi Familia Progresa (MIFAPRO) in Guatemala became increasingly politicised through clientelistic vote buying and threats of programme expulsion in case of non‐electoral support. It finds that MIFAPRO constitutes an emblematic case with mixed effects that are particularly relevant in the diffusion of CCTs to other developing countries.  相似文献

Research concerning the relationship between female status and demographic behaviour has largely concluded that community level influences are most important, while status and autonomy at the individual level are far less so. This consensus, however, rests on an untested a priori typology of women’s status and tenuous assumptions about the measurement of defined status dimensions on the individual level. To better understand the potential influences of both community and individual elements it is necessary to take a step back and assess the validity of the constructs of autonomy used. This work uses a latent variable measurement modelling framework to test both the dimensionality of women’s status and the appropriateness of using simple additive index scaling in constructing measures of women’s status on the individual level using questions from the Demographic and Health Surveys status-of-women module in India for 1998/1999.  相似文献

Adolescent depression may be associated with future relationship problems that have long‐term consequences given the developmental importance and health benefits of forming committed unions in emerging adulthood. The authors examined associations between emotional and behavioral indicators of adolescent depression (depressive symptoms, alcohol problems, and suicidal ideation) and romantic relationship and union formation and dissolution in emerging adulthood (n = 14,146) using the National Longitudinal Study of Adolescent Health. Adolescent alcohol problems were associated with more romantic relationships in emerging adulthood. Emerging adults with depressive symptoms or alcohol problems in adolescence were significantly more likely to enter into a cohabiting union, and those with adolescent alcohol problems were less likely to marry. Cohabiting emerging adults with a history of adolescent depressive symptoms were less likely to marry, whereas suicidal ideation was associated with a decreased likelihood of cohabitation dissolution. Implications for future research are discussed.  相似文献

We describe a significant practical consequence of taking anthropic biases into account in deriving predictions for rare stochastic catastrophic events. The risks associated with catastrophes such as asteroidal/cometary impacts, supervolcanic episodes, and explosions of supernovae/gamma‐ray bursts are based on their observed frequencies. As a result, the frequencies of catastrophes that destroy or are otherwise incompatible with the existence of observers are systematically underestimated. We describe the consequences of this anthropic bias for estimation of catastrophic risks, and suggest some directions for future work.  相似文献

We discuss the status of the scientist-practitioner model in marriage and family therapy (MFT) doctoral programs. Issues discussed include a lack of faculty research role models in doctoral programs, "farming out" the majority of research courses to other disciplines, problems with curriculum, and how the culture of MFT does not support research. We also present suggestions for improving doctoral research training. The goal is to improve the quality of research training in doctoral programs. We hope that this will help change the culture of MFT to include research as one of its primary goals and greatest assets.  相似文献

This article explores the development of a scheme to use Information and Communication Technology (ICT) in the training of individuals with severe functional impairments. Computers were used as an integral part of a rehabilitation programme for training, and the authors found that the resource was a useful addition to other treatment methods. This article describes the development and subsequent setting up of computers for training and how the study progressed. The study used a somewhat unique bottom up approach that first trained care-giving staff in computer skills. The caregivers in turn worked with and trained some of those they served. This learning strategy drew upon the concept of learning, empowerment and the motivation of all involved in a system and process. The study found that by using ICT all involved felt a greater sense of empowerment and improvement in the quality of life. That caregivers were involved at all stages was valuable in that they felt an ownership of the process and that they also benefited from being involved because they also learned new skills.  相似文献
