The application of the exponential model is extended by the inclusion of new nonhuman primate (NHP), rabbit, and guinea pig dose‐lethality data for inhalation anthrax. Because deposition is a critical step in the initiation of inhalation anthrax, inhaled doses may not provide the most accurate cross‐species comparison. For this reason, species‐specific deposition factors were derived to translate inhaled dose to deposited dose. Four NHP, three rabbit, and two guinea pig data sets were utilized. Results from species‐specific pooling analysis suggested all four NHP data sets could be pooled into a single NHP data set, which was also true for the rabbit and guinea pig data sets. The three species‐specific pooled data sets could not be combined into a single generic mammalian data set. For inhaled dose, NHPs were the most sensitive (relative lowest LD50) species and rabbits the least. Improved inhaled LD50s proposed for use in risk assessment are 50,600, 102,600, and 70,800 inhaled spores for NHP, rabbit, and guinea pig, respectively. Lung deposition factors were estimated for each species using published deposition data from Bacillus spore exposures, particle deposition studies, and computer modeling. Deposition was estimated at 22%, 9%, and 30% of the inhaled dose for NHP, rabbit, and guinea pig, respectively. When the inhaled dose was adjusted to reflect deposited dose, the rabbit animal model appears the most sensitive with the guinea pig the least sensitive species. 相似文献

Recently C. Czymara and A. Schmidt-Catran published in this journal (KZfSS 2016 (2)) a factorial Survey-Experiment to contribute to the current debate on the inflow of refugees in Germany. The authors concluded from their Survey-Experiment that in particular highly qualified immigrants who show little culture distance should get accepted in Germany, while for instance Muslim immigrants would be more strongly rejected. In this comment it is argued that authors’ results probably suffered from a strong confounder bias. The employed experimental design also allows for a lot of alternative interpretations. Therefore, readers of the original article or further users of the data should be more cautious when interpreting the results. 相似文献

This article offers a new definition of military cultural competence based on a review of the literature. As a starting point, the defining characteristics of military culture is discussed and includes the chain of command, military norms, and military identity. Having laid this groundwork, the multidimensionality of military cultural competence—attitudinal, cognitive, behavior—is discussed. Clinical applications of these various competencies are provided. 相似文献

Older Adults’ Experiences of Sexual Difficulties: Qualitative Findings From the English Longitudinal Study on Ageing (ELSA) 总被引:1,自引:0,他引:1
There is a growing body of evidence demonstrating that sexual activity is important to the quality of life of older adults, and that it can be influenced by physical, psychological, and social factors. However, older adults’ experiences of sexual difficulties remain relatively unexplored. This article draws on qualitative data collected as part of the English Longitudinal Study of Ageing (ELSA). Participants answered a Sexual Relationships and Activities Questionnaire (SRA-Q), which included an open comment box for further details, 1,084 (1/7) of which were completed. These data were analyzed using Template Analysis, and findings on the experiences of sexual difficulties are presented in this article. Sexual difficulties were contextualized within the couple relationship and could be detrimental to the relationship, particularly if the partner would not seek professional help. Participants reported that sexual difficulties could also have a negative impact on psychological well-being, described mainly as frustration, depression, and sadness. For some participants the supportive nature of their relationship buffered these impacts. Few had sought professional help; those who had reported helpful and unhelpful experiences. These findings add to the limited evidence base and have implications for health care in the context of global aging and a growing recognition of older adults’ sexual rights. 相似文献

Parenting is a critical factor in substance abuse prevention. Positive parenting behaviors are identified as a protective factor for substance abuse among youth. Limited research exists that investigates the role of parenting practices on minority youth substance use. The present study seeks to examine correlates between parenting and recent alcohol use among African American youth. Specifically, to what extent do African American students report experiencing specific parenting behaviors that are measured by the National Household Survey on Drug Use and Health?, do specific parenting behaviors increase the risk of recent alcohol use among African American youth?, does the impact of parenting behaviors on recent alcohol use among African American youth differ based on sex (males and females) and age category (12–13, 14–15, and 16–17 years old) were examined in this study? Logistic regression analysis of the National Household Survey on Drug Use and Health was conducted to examine the research questions. Findings indicated that parenting behaviors was associated with recent alcohol among youth. Significant differences were found for males, females, 12–13, 14–15, and 16–17 years olds. Study findings demonstrate the importance of positive parenting behaviors in youth alcohol prevention. Program specialists may target parenting as a means of preventing and reducing youth alcohol use among African American youth. 相似文献

The social economy (SE) is alternatively conceptualized as a third sector (between the private and public sector); or by a typology of the organizations involved (such as cooperatives, non-profit organizations and social enterprises); or by the principles and values driving such activities (such as cooperation, mutual benefit, and democracy). One important consideration is often overlooked, namely that the SE emerges in different forms and with varied emphases depending on location. The SE is ‘place-based’—rooted in specific geographic, historical, cultural, and socioeconomic settings. This article explores the conceptualization of the SE in the Bolivian context from the perspective of government and civil society actors. The research took place after the country recognized the importance of the social, cooperative and community economy in their new constitution and found that the understanding of the SE in Bolivia relates strongly to the country’s indigenous and colonial heritage. 相似文献

Delinquent peers have a strong influence on adolescent delinquent behavior. However, few studies have investigated adolescents’, and in particular young females’, own perspectives of the role of peers on their delinquent behavior. The purpose of the present study was to explore how young female offenders described their delinquent behavior and more specifically the role they assign to peer relations in committing or avoiding delinquent acts. Nine female adolescents, sentenced to youth service, were interviewed, and the data was analyzed using the Consensual Qualitative Research (CQR) method. The results showed that committing crimes and taking drugs with peers were portrayed as a way for the female delinquents to socialize. Delinquent and pro-social activities with peers appear to serve similar developmental functions in the sense that it is described to fulfill the same developmental needs. The young offenders also described collectively created pressures and norms in the peer group as the main contributing factor to their norm-breaking behavior, where they described being both recipients and producers of influence in the group. Another important finding was that the female offenders showed an awareness of the importance of pro-social peers and the need to eliminate delinquent friends from their peer network in order to help them refrain from deviant behavior. Implications for prevention and intervention are discussed. 相似文献

This study considers key value differences between leaders of two types of social ventures: for-profit social benefit corporations and nonprofit organizations. The research question asks to what degree the value sets of leaders of benefit corporations are congruent with those of similarly situated individuals in nonprofit organizations. The results show the values of leaders working in benefit corporations and nonprofit organizations are in many ways aligned, but there are notable statistical differences. A sectoral association of values is also present with employees in both types of organization, especially when the previous work experience of employees is considered. 相似文献

Understanding how different forms of supervision support good social work practice and improve outcomes for people who use services is nearly impossible without reliable and valid evaluative measures. Yet the question of how best to evaluate the quality of supervision in different contexts is a complicated and as-yet-unsolved challenge. In this study, we observed 12 social work supervisors in a simulated supervision session offering support and guidance to an actor playing the part of an inexperienced social worker facing a casework-related crisis. A team of researchers analyzed these sessions using a customized skills-based coding framework. In addition, 19 social workers completed a questionnaire about their supervision experiences as provided by the same 12 supervisors. According to the coding framework, the supervisors demonstrated relatively modest skill levels, and we found low correlations among different skills. In contrast, according to the questionnaire data, supervisors had relatively high skill levels, and we found high correlations among different skills. The findings imply that although self-report remains the simplest way to evaluate supervision quality, other approaches are possible and may provide a different perspective. However, developing a reliable independent measure of supervision quality remains a noteworthy challenge. 相似文献

The importance of commitment from the point of view of companies or organizations is discussed controversially in recent years. On the one hand, a key competitive advantage is seen in the field of human resources. At the same time, very different forms of employment flexibilization can be observed. These different approaches are shown in this article and the versatile embedding of work such as the perception of disposition possibilities in terms of time, individual room for maneuver or even the experienced social justice. All of these dimensions have the potential to portray themselves as faultlines in organizations and thus have an impact on the binding in organizations. 相似文献
