Pediatric radiologists play a key role in the detection of child abuse through the identification of characteristic injury patterns. Emergency radiologists have the potential to play an equally important role in the detection of elder physical abuse; however, they currently play little to no part in this effort. We examine the reasons behind this limited role, and potential strategies to expand it, by interviewing attending faculty from Emergency Radiology, Geriatrics, Emergency Medicine, Pediatric Radiology, and Pediatrics. Our interviews revealed that radiologists’ contribution to elder abuse detection is currently limited by gaps in training, gaps in knowledge about imaging correlates, and gaps in inter-team clinical communication. Specifically, radiographic interpretation of elder trauma is severely restricted by lack of communication between frontline providers and radiologists about patients’ injury mechanism and functional status. Improving this communication and re-conceptualizing ED workflow is critical to expanding and optimizing radiologists’ role in elder abuse detection.  相似文献

Many parents in Britain make huge financial sacrifices to send their children to private schools. Are those sacrifices worthwhile? What return, if any, do they get? Do their children end up in better careers, earning more, than if they have been educated at the expense of the state? Francis Green, Stephen Machin, Richard Murphy and Yu Zhu examine who exactly benefits from the privileges of the Old School Tie.  相似文献

Single session therapy (SST) is grounded in the belief that clients and families can effect change after one therapeutic encounter, using their own resources, with brief support and assistance from therapists. SST has been found to be an effective intervention for children, young people, and their families presenting with a wide range of difficulties. Research in child and adolescent mental health has shown that over 50% of families find one SST encounter is enough with no need for further specialist input. This study aims to explore family member experiences of SST (undertaken as single session family therapy and termed hereafter SSFT) as an initial intervention in a regional child and adolescent mental health service (CAMHS), specifically in terms of worry, confidence, and satisfaction outcomes. An exploratory, mixed methods convergent design was utilised using a combination of open questions and Thurstone scales. All eligible family members were invited to complete questionnaires before and after the SSFT, asking about level of worry, confidence, and overall satisfaction with SSFT. Quantitative and qualitative findings indicated most family members had a positive experience of SSFT, although differences were found between young people, parents, and siblings. Overall, family members’ level of worry decreased, while only parental confidence in managing the presenting issue(s) increased. Over half of the families did not require further contact with CAMHS following the SSFT. Our findings support previous research that SSFT is an effective, family-inclusive, and well received intervention for a variety of mental health issues facing children and young people. SSFT could be considered a beneficial and well received first response for the majority of CAMHS clients, which prioritises a family-inclusive approach. Future research could focus on attaining a more in-depth understanding of individual family member experiences with a view to improving SST delivery.  相似文献

Animal body sizes in urban areas often differ from nearby rural areas, which may impact population fitness and dynamics. We examined the effects of urbanization on larval body sizes of two species of salamanders, the two-lined salamander (Eurycea cirrigera) and the northern dusky salamander (Desmognathus fuscus). Specifically, we utilized a before-after control-impact (BACI) study design which allowed for the assessment of differences in larval body size between multiple control and impacted sites over a 5 year period. We found a decrease in larval body size in both species at the impacted sites compared to control sites in the first year after urbanization, followed by generally larger body sizes in urban sites compared to control sites in years 3–5, and significantly so in year 4. Using generalized linear models, we found support that larger body sizes post impact in urbanized streams may be due to warmer stream water temperature and decreased abundance of larvae. Both E. cirrigera and D. fuscus are well known for their ability to persist in urbanized streams; our data suggest that despite overall lower abundances in urban streams, persistence may be due to increases in larval body size and, potentially, post-metamorphic benefits.  相似文献

This chapter examines the societal drivers of environmental change in South Florida's Everglades region during the past 150 years. This historical geography is developed through the use of a conceptual framework constructed to facilitate the analysis of human–environment interactions and nature–society systems of ecological degradation and restoration at the regional scale. The framework is composed of four basic interlinked components: interaction mechanisms (e.g., land use, direct resource utilization, pollution and external inputs, resource competition), feedback mechanisms (e.g., basic needs, quality of life, environmental ethics), control systems (e.g., governmental regimes, legal institutions, resource management), and the societal context (e.g., population and demographic patterns, social structure and organization, technology, economic conditions, societal values). A primary objective of this chapter is to determine the presence and importance of each of these components during the process of environmental change over the period of study—1845 to 1995.Data for the analysis are drawn from primary and secondary sources on the environmental, social, economic, and political history of South Florida. The results indicate that although elements of each component were present throughout the entire period, different elements of each component play more significant roles at differing moments. The shifts in importance are used to define four periods of environmental change within the region. The periods are the following: (1) frontier settlement (1845–1900), focused on basic needs acquisition and direct utilization of the resource base; (2) drainage and land conversion (1900–1930), focused on population and economic growth, land use change, and increased resource management and competition; (3) flood control and consolidation (1930–1950), focused on inputs from external sources and infusion of advanced technology, the development of governance and social structures, and increased concern for quality of life; (4) postwar boom, flood control, and water supply (1950–1970), focused on accelerated land use change, increased pollution, and further heightened concern for local quality of life; and (5) period of limits (1970–1995), focused on pollution and resource competition concerns, a developing regional environmental ethic and amenity values, and environmental preservation governance strategies.Taken together, the five periods represent the differing nature–society systems through which South Florida's regional ecosystem was degraded and which is now entering a phase of restoration.  相似文献

Existing research has explored the ways the mainstream news media covers Muslims and Islam, but few studies have examined Muslims’ reactions to this reporting. Studies that have investigated this issue have identified that the responses of Muslims to news media coverage tend to be largely negative because of the lack of Muslim news sources, the stereotypical representation of Muslims in news coverage, the portrayal of Muslims as the enemy within, and the conflation of Muslims with terrorism. This paper further explores the attitudes of Muslims to news media coverage of Islam and Muslims by drawing on data from 14 focus groups (N?=?104 participants) conducted with Australian Muslims. Similar to previous research, findings reveal that Australian Muslims are highly critical of news media coverage of Islam and Muslims and express concern about the divisiveness that such portrayal can have for Australian society. However, the study participants also had positive comments to make about the news media. Possible solutions to negative news media portrayals of Muslims are considered.  相似文献
