When children go missing, authorities sometimes release age progressed images that are intended to approximate the person's current appearance. The current studies measured the influence of the range between the time when the child went missing and the age portrayed in the age progression on the similarity between the progressions and current images of the targets. Experiment 1 examined whole face images and Experiment 2 examined internal features only. Eight artists were recruited to produce progressions at three age ranges. Also included were averaged (morphed) images made of progressions of the same individual at a given range by different artists. Progressions across shorter ranges produced images more similar than those across longer ranges, and target comparisons yielded higher similarity ratings than foil comparisons. Although there was much variability among artists, the morphed images performed better than the average rating given to all age progressions.  相似文献

Occupational health providers (OHPs) and other clinicians who assess readiness to work have a difficult task in assessing return to work for healthcare professionals (HCPs) with substance use disorders (SUDs). About 10 to 15 % of HCPs will misuse drugs or alcohol at some time in their career, yet they are often reluctant to seek help. This paper reviews the clinical challenges of assessing SUDs in HCPs, including risk factors, prognosis, and limited evidence base for work restrictions. Furthermore, ethical and legal challenges throughout the return to work process are reviewed for stakeholders such as HCPs with SUDs, OHPs, other providers, employers, and the public at large. Suggestions are made for stakeholders, particularly for OHPs and other providers, who are navigating this complex environment.  相似文献

Low back pain (LBP), a leading cause of disability, has been linked with profound economic, personal, and social costs (Hills 2006; World Health Organization 2003). This significant effect propels research in identifying modifiable risk factors that protract LBP; these factors can be targeted in early intervention (EI) (Pransky, Journal of Occupational & Environmental Medicine, 49(3):249–251, 2007; Schultz et al., Journal of Occupational Rehabilitation, 17:327–352, 2007, Journal of Occupational Rehabilitation, 18(2), 140–151, 2008; White et al. 2013). This randomized controlled study evaluated the effectiveness of two approaches, fixed versus flexible, in delivering proactive, interdisciplinary EI with 63 workers within a workers' compensation interdisciplinary case management setting (i.e., WorkSafeBC, Canada). Off-work 4 to 10 weeks post-back injury, the workers were also at risk of protracted work disability (N?=?24 at high risk; N?=?39 at moderate risk). Fixed, protocol-driven, interdisciplinary, multimodal, clinical, occupational, and case management-based EI was compared with a flexible, individual need-driven EI with the same modalities as the fixed approach. Results showed a significant narrowing of the outcome gap between the two interventions. High-risk injured workers tended to benefit more from a fixed, protocol-driven approach, as shown in the pilot study (Schultz et al. Journal of Occupational Rehabilitation, 18(2), 140–151, 2008). The results indicated that moderate-risk workers benefitted from a more flexible, need-based, individual, and low-intensity approach as compared with a fixed approach. The flexible approach for moderate-risk workers was also less costly and consumed fewer rehabilitation and health care resources. Recommendations for future research and practice included larger sample sizes, controllability of research interventions, risk for disability-EI matching, and conditions under which a flexible delivery of multimodal EI is more efficacious than a fixed approach, and vice versa.  相似文献

Ernesto Laclau argues that Saussurean structural linguistics is one framework necessary for a post-Marxist understanding of political identities and new social movements. Disrupting the distinction between the discursive and the political, he provides insight into the formal properties of identity, difference, universality and particularity. However, this disruption means that his work is relevant not only to political theory per se but has retroactive value for understanding semiotics and signification. By considering methodological problems encountered during an analysis of an anti-war poster genre, this essay suggests that Laclau's concept of empty signifiers enables a novel understanding of genre. His schema complements approaches that emphasize the analysis of content and the analysis of audience reception, broadly conceived. Between the poles of content and reception, there are structural or relational properties enabling the contingent stability and meaningfulness of genre. These properties include the differential nature of a genre's identity, and a genre's discursive reliance on a radical exclusion.  相似文献

This article uses household data from Nepal's two major populated regions (and 27 of 59 districts within those regions) to examine fuelwood consumption and production. In contrast with a purely market assessment, household analysis includes production which is consumed in the producing household. The household regressions yield coefficients and elasticities that are very different from and more reliable than a comparable assessment of market demand and supply. Household results generally support the hypotheses that expenditures on fuelwood are a small share of total household activity and that fuelwood is not sufficiently scarce to alter household behaviour. Fuelwood is sufficiently scarce, however, to alter behaviour for those households in the hill region that do not participate in market exchange. These households may be the best targets for public market interventions designed to alter fuelwood supply and deforestation.  相似文献

Since previous studies have found that crime rates vary by immigrant group there is a need to dis‐aggregate immigrants by country of birth in order to obtain a more accurate representation of the relationship between migrants and crime. This study examines data from six countries (Australia, Canada, France, Italy, the Netherlands, and the U.S.A.) on the country of birth of their inmate populations. The following observations are reasonable conclusions from the data available. First, the percentages of each home country's inmate population that is foreign‐born varies remarkably. Second, in general foreign‐born inmates tend to come from regions outside the region within which the host country was located, though in most cases from regions that were proximate. Third, given the small number of countries reporting, it is intriguing that just a small number of countries and regions can account for such a high proportion of a home country's inmate population if one includes the numbers of a country's citizens who are housed in foreign prisons as part of that original country's inmate population. The paper concludes with a discussion of a number of policy implications that flow from these findings.  相似文献

Transparency is considered a key value for trustworthy governments. However, the effect of transparency on citizens’ trust across national cultures is overlooked in current research. This article compares the effect of transparency on trust in government in the Netherlands and South Korea. The effect is investigated in two similar series of three experiments. The authors hypothesize that the effect of transparency differs because the countries have different cultural values regarding power distance and short‐ and long‐term orientation. Results reveal similar patterns in both countries: transparency has a subdued and sometimes negative effect on trust in government. However, the negative effect in South Korea is much stronger. The difference in the magnitude of transparency's effect suggests that national cultural values play a significant role in how people perceive and appreciate government transparency.  相似文献

Since the mid-1990s, academic and policy communities have debated the risk posed by terrorist use of chemical, biological, radiological, or nuclear (CBRN) weapons. Three major schools of thought in the debate have emerged: the optimists, the pessimists, and the pragmatists. Although these three schools of thought draw on the same limited universe of data on CBRN terrorism, they arrive at strikingly different conclusions. Given the highly subjective process of CBRN terrorism risk assessment, this article analyzes the influence of mental shortcuts (called heuristics) and the systemic errors they create (called biases) on the risk assessment process. This article identifies and provides illustrative examples of a range of heuristics and biases that lead to the underestimation of risks, the overestimation of risks and, most importantly, those that degrade the quality of the debate about the level of risk. While these types of biases are commonly seen as affecting the public's perception of risk, such biases can also be found in risk assessments by experts. The article concludes with recommendations for improving the CBRN risk assessment process.  相似文献

The 1961 Kuwait crisis stands as a key event in the evolution of American strategic thinking on the Persian Gulf. Following Iraqi threats to annex Kuwait, Britain despatched a sizable military force to the Emirate hoping to pre-empt an Iraqi invasion. When the Iraqi invasion failed to occur, Britain was forced to weather a political maelstrom as it struggled to withdraw its forces. Although the United States was largely an observer to the crisis, London's actions required Washington to acknowledge the limits of Britain to meet the political challenges of the Middle East and protect Western interests in the region. This realisation provided the impetus for Washington to diversify its strategy in the Persian Gulf and increasingly seek regional solutions for its security concerns.  相似文献
