When searching underwater crime scenes or disaster scenes for fragmentary human remains, it may be advantageous for forensic divers to be able to detect the presence of bones and teeth among other marine materials (such as shells and rocks). In terrestrial environments, this can typically be accomplished by visual and instrumental methods, but underwater conditions make it difficult to employ detection and sorting techniques in these environments. This study investigates fluorescence of bones and teeth and other marine materials using a submersible alternate light source (ALS) and concludes that an ALS can be a useful tool for detecting bones and teeth in underwater searches as well in terrestrial searches and laboratory environments. The results could impact the methods and equipment used by forensic divers and forensic anthropologists when searching for skeletal remains, potentially increasing the quantity and efficiency of forensic evidence recovered. 相似文献

African American males experience poor academic performance, high absenteeism at school, and are at increased risk of being involved in violence than other racial groups. Given that the educational outlook for African American males appears bleak, it is important to assess the aspirations of these adolescent males in order to find the gap between aspirations and educational attainment. In order to promote positive development within this population, it is essential that factors that affect African American males be identified. A survey was administered to male students attending elementary, middle, and high schools in a local school district. A cross-sectional study was conducted to examine the career and educational aspirations of African American males. A total of 473 males were surveyed: 45% African American, 22% Caucasian, 13% biracial, and 19% Other (including Asian American, Hispanic, Native American). The results revealed that African American males aspired to attend college at the same rate as other ethnic groups. Also, African American males were more likely to aspire to be professional athletes than males from other ethnic groups. Important factors to consider when designing a program are discussed as well as future research and limitations. 相似文献

Over the past few decades researchers have begun to examine the importance of understanding positive youth development and the many contexts in which youth find themselves. The social contexts in which adolescent development occurs are varied and complex, particularly the development among African American youth. African American youth are faced with a number of challenges including living in single-parent homes, high teen pregnancy rates, and poor neighborhoods, yet many of these youth continue to thrive. The purpose of this study was to examine the relationship between family structure (single-parenting) and adolescent outcomes such as educational aspirations and sexual activity among African American adolescent youth aged 12-17. Approximately 462 African American youth were surveyed. A number of positive results emerged; for instance, there was a negative correlation between family structure and educational aspirations. The number of parents in the home did not interfere with youth wanting to complete high school and go on to college (r?=?-?.218, r2?=?.04, p?.05). The results also showed that as educational aspirations increased, the number of sexual partners decreased (r?=?-?.141, meaning that the more adolescents reported a desire to complete high school, they were less likely to report having sexual intercourse. These positive results should be promoted among African American youth so that those faced with these challenges will note that others have overcome and accomplished their goals. In this population educational aspirations were important. Limitations and future research are discussed. 相似文献

The purpose of this article was to assess the overall health behaviors of African American emerging adults who live in a Midwestern city. Two hundred participants, ages 18-25, completed a 129-item survey. Results indicate that African American emerging adults are engaged in relatively healthy behaviors (i.e., physical activity, low substance use). The results also showed that within the emerging adult developmental period, there are differences in behavior for those who are in the younger (18-20) versus those that are older (21-25) in the developmental period. Limitations, future research, and implications for practice will also be discussed. 相似文献

Sub‐national government capital spending is important for both public service delivery and economic development. Currently, Indonesian sub‐national public capital spending appears barely sufficient to cover the annual depreciation of its fixed assets. A substantial proportion of local government investment spending goes to create relatively unproductive assets, such as administrative office buildings. Sub‐national governments finance their capital acquisitions out of gross operating budgets and have thus far not used, to any great extent, either borrowed funds or their significant cash reserves for such purposes. Indonesian sub‐nationals need to spend more on capital than they do now and also need to focus that spending on more useful types of infrastructure. The major constraints to increasing capital spending at the sub‐national level are not related to a dearth of finance, but regulatory rigidities in budget preparation and implementation and, most importantly, a lack of capacity to plan, design and implement investment projects.

Participatory democracy was one of the core tenets of the New Left student movements that emerged in Australia in the 1960s. However, scant attention has been given to the idea within the literature on the New Left. This article examines an experiment in participatory democracy that took place in the Department of Philosophy at Sydney University in the 1970s. Following a series of strikes, the Philosophy department was split in two, with one half, the Department of General Philosophy, operating under a democratic constitution for six years from 1973 to 1979. This case study reveals a great deal about the intellectual history of the student New Left and the centrality of participatory democracy within it. 相似文献

Scholars have spent a great deal of effort examining the effects of negative advertising on citizens’ perceptions of candidates. Much of this work has used experimental designs and has produced mixed findings supporting one of two competing theories. First, negative ads may harm candidates who sponsor them because citizens tend to dislike negativity. Second, negativity may drive down citizens’ support for the targeted candidate because the attacks give people reasons to reject the target. We argue that the mixed findings produced by prior research may be driven by a disregard for campaign dynamics. We present a critical test of these two theories using data drawn from 80 statewide elections—37 gubernatorial and 43 U.S. Senate contests—from three election years and public opinion polling collected during the last 12 weeks of each campaign. We find that a candidate’s support declines as her advertising strategy includes a higher proportion of negative ads relative to her opponent and that this process unfolds slowly over the course of the campaign. 相似文献

AbstractThis paper reflects on responses to Bangladesh’s Rohingya refugee crisis in the weeks that followed the increased numbers of Rohingya refugees who arrived from Myanmar after 24 August 2017. Drawing on literature on the local and international dimensions of humanitarianism, and the analytical lens of performance, it explores narratives of helping in relation to the shifting character of Bangladesh’s civil society, changing expressions of local and international religious sentiments, and the importance of understanding both formal and informal responses historically in the context of Bangladesh’s own experiences as a country born from a crisis in which citizens became refugees fleeing state-sponsored violence. 相似文献
