Bruises are often difficult to detect on victims of violence, potentially impacting investigation and prosecution. The purpose of our randomized controlled trial was to measure the effectiveness of an alternate light source (ALS) within visible and long ultraviolet spectrums at improving bruise detection compared to white light over time. We also examined the effects of skin color, age, gender, localized fat, and injury mechanism on bruise detection. Participants included 157 healthy adults with balanced sampling across six skin color categories. Bruises were created under the controlled application of a paintball pellet and dropped weight to one upper and lower arm, respectively. Using a crossover design, both bruises were examined 21 times over 4 weeks. Ten different wavelength (350–535 nm) and filter (yellow, orange, red) combinations were used. Multilevel models were used to analyze 2903 examinations on both upper and lower arms. Results in multivariable models showed after controlling for other covariates 415 and 450 nm using a yellow filter had greater odds of detecting evidence of bruising than white light (Upper Arm: 415 nm: OR = 5.34, 95% CI: 4.35–6.56; 450 nm: OR = 4.08, 95% CI: 3.36–4.96). Under either light source, being female and having more localized fat had increased odds of detecting bruises created by the dropped weight (female: OR = 2.96, 95% CI: 2.37–3.70; fat: OR = 1.21, 95% CI: 1.09–1.34). Our results support ALS as an appropriate tool to enhance concurrent physical assessment of bruises in the presence of known history of injury. Future development and evaluation of clinical practice guidelines for ALS application are needed. 相似文献

Research on achievement gaps by race/ethnicity and poverty status typically focuses on each gap separately, and recent syntheses suggest the poverty gap is growing while racial/ethnic gaps are narrowing. In this study, we used time-varying effect modeling to examine the interaction of race/ethnicity and poverty gaps in math and reading achievement from 1986–2005 for poor and non-poor White, Black, and Hispanic students in three age groups (5–6, 9–10, and 13–14). We found that across this twenty-year period, the gaps between poor White students and their poor Black and Hispanic peers grew, while the gap between non-poor Whites and Hispanics narrowed. We conclude that understanding the nature of achievement gaps requires simultaneous examination of race/ethnicity and income. 相似文献

This reflection draws upon two recent ‘moments’ in British sexuality politics—a series of Parliamentary debates on Global LGBT rights and Brighton Pride’s campaign to ‘Highlight Global LGBT Communities’. It contrasts these two moments in order to demonstrate how, at a time when LGBT rights have ostensibly been ‘won’ in the UK, there is an increasing tendency to shift focus to the persecution of SOGI minorities elsewhere in the world. This shift in focus sets up a binary of here versus there that is politically persuasive but ultimately limited and limiting. By reflecting on the way that this growing trend of creating sexual politics elsewhere occurs in two very different locations in British politics and activism, we seek to begin a conversation about the relational affects of placing sexual politics ‘elsewhere’. 相似文献

Policy makers have long recognized the importance of achieving a representative federal bureaucracy, but the four most recent presidents have expressed divergent views about policies designed to achieve this goal. Meanwhile, there have been widespread perceptions among federal employees that the administrations' ideologies have had a direct impact on the opportunities of minorities, women, and white men for advancement. Using government-wide data from 1979 to 1996, this article examines whether such employment opportunities have varied in the manner suggested by these perceptions. We find little evidence of a correlation between the president's views on affirmative action and minority and female representation in the overall federal workforce. Moreover, the curtailment of promotion opportunities during the Reagan and Clinton administrations has affected all groups nearly equally. Potential presidential influence has been more notable in the representation of women and minorities in politically appointed and career senior executive jobs. We conclude that equal employment opportunity and affirmative action policies have remained basically intact during the 18-year period, but that recent court decisions, along with efforts to reduce the size of government, may slow progress toward achieving a representative bureaucracy. 相似文献

A modern budget reform, performance‐based budgeting (PBB) emphasizes the measurement of government performance by agencies and public servants. In this article we define PBB as requiring strategic planning regarding agency mission, goals and objectives, and a process that requests quantifiable data that provide meaningful information about program outcomes. Performance‐based budgeting requirements are now pervasive in the states. Of forty‐seven states with PBB requirements, thirty‐one have legislated the process to be conducted, while sixteen have initiated the reform through budget guidelines or instructions.1What remains unknown, yet of vital interest to state administrators, their staff, legislators, and citizens, regards implementation status of PBB systems. How many states are utilizing a PBB process as prescribed by law or administrative directive? And if PBB has been implemented, has it been successful regarding improvement of agency effectiveness and decision making about spending? Perhaps most importantly, has PBB influenced appropriation decisions?. This research is based on responses to a mail survey of executive and legislative budgeters regarding the PBB system established in their state. Results discussed in this article consider budgeters’ response about PBB implementation status and effectiveness as conducted. We find that there are differing perceptions across the branches of government regarding both the extent of PBB implementation as well as its success. Results show that states with better‐known PBB systems have not necessarily realized greater success in terms of effectiveness from this budget reform than states with less popularly known systems, at least as perceived by the budgeters included in this article. 相似文献

The United States (U.S.) population structure is currently in a state of flux with one of the most profound changes being the increasing number of people referred to as Hispanic. In the U.S., much of the identification criteria for a biological profile are based on American Black and White individuals from anatomical collections. Using metric data from the Forensic Anthropology Data Bank (FDB), this paper will attempt to explore several issues that forensic anthropologists face when confronted with Hispanic remains. These will involve estimation of sex, height, and ancestry, the initial components of a biological profile. Discriminant function analyses indicate that American White criteria provide poor estimations of sex when applied to Hispanics and that ancestry estimation of Hispanic crania is difficult. Additionally, a new linear regression equation is presented that estimates stature for Hispanic individuals, although population specific criteria are still needed for Hispanic individuals from diverse geographical origins. 相似文献
