To evaluate how the media frames veterans of the wars in Iraq and Afghanistan, this study systematically assesses the discourse on Iraq and Afghanistan veterans in the New York Times and Washington Post from 2003 to 2011. Our analysis of a stratified sample of 151 articles featuring veterans from either the wars in Iraq or Afghanistan finds that the media frames veterans as damaged by their service but deserving of government benefits and social assistance. When the media frames veterans as actively engaging in society, their social engagement is often because of or despite their injuries or mistreatment. We find interplay between victimization and deservingness such that depictions of the cohort as physically and mentally damaged complement and justify arguments for a sustained high level of benefits to accommodate the needs of veterans. We thus argue that generous benefits for veterans partly stem from their depiction as having suffered from their service. 相似文献

Fine particle (PM(2.5)) emissions from traffic have been associated with premature mortality. The current work compares PM(2.5)-induced mortality in alternative public bus transportation strategies as being considered by the Helsinki Metropolitan Area Council, Finland. The current bus fleet and transportation volume is compared to four alternative hypothetical bus fleet strategies for the year 2020: (1) the current bus fleet for 2020 traffic volume, (2) modern diesel buses without particle traps, (3) diesel buses with particle traps, and (4) buses using natural gas engines. The average population PM(2.5) exposure level attributable to the bus emissions was determined for the 1996-1997 situation using PM(2.5) exposure measurements including elemental composition from the EXPOLIS-Helsinki study and similar element-based source apportionment of ambient PM(2.5) concentrations observed in the ULTRA study. Average population exposure to particles originating from the bus traffic in the year 2020 is assumed to be proportional to the bus emissions in each strategy. Associated mortality was calculated using dose-response relationships from two large cohort studies on PM(2.5) mortality from the United States. Estimated number of deaths per year (90% confidence intervals in parenthesis) associated with primary PM(2.5) emissions from buses in Helsinki Metropolitan Area in 2020 were 18 (0-55), 9 (0-27), 4 (0-14), and 3 (0-8) for the strategies 1-4, respectively. The relative differences in the associated mortalities for the alternative strategies are substantial, but the number of deaths in the lowest alternative, the gas buses, is only marginally lower than what would be achieved by diesel engines equipped with particle trap technology. The dose-response relationship and the emission factors were identified as the main sources of uncertainty in the model. 相似文献

This paper compares flexible automation with labor‐intensive manufacturing processes in a batch production environment and considers learning, forgetting, inventory carrying costs, setup costs, production demand volume, previous production experience, and the proportion of material to labor cost. While flexible automation typically can reduce setup times, and therefore inventory carrying costs through smaller optimal batch sizes, the results of this research show that the effect of forgetting on relative cost savings is difficult to predict in some situations. When using optimal lot sizes in both the automated and labor environments, cost savings from flexible automation may be smaller than expected or may occur in different ways than anticipated. 相似文献

In this paper we analyze the preferences about job security using tools from behavioral economics. We focus on the non-pecuniary value of job security and specifically whether this value depends on the current position of employees as tenured or non-tenured. Using a sample of 107 Israeli social workers, randomly allocated between tenured and non-tenured positions, we demonstrate that the non-pecuniary value of job security is about 20% of the wage. We also found that this value depends on the point of reference of the employees. Those with tenure place a higher value on job security, as do those with a higher level of loss aversion. 相似文献

In this paper, some recent and classical tests of symmetry are modified for the case of an unknown centre. The unknown centre is estimated with its α-trimmed mean estimator. The asymptotic behaviour of the new tests is explored. The local approximate Bahadur efficiency is used to compare the tests to each other as well as to some other tests. 相似文献

Accompaniment, or the intentional practice of presence, emphasizes processes and relationships over outcomes, with the ultimate goal of leveraging privilege and collectively changing destructive systems. Though not widely recognized in social work, accompaniment has been applied globally. Here, we outline an overview of accompaniment, including how it has been applied in social work literature and practice. We then propose community-based accompaniment as an approach to complement traditional models of social action as a necessary, yet accessible way to further advance community organizing in social work education and practice, and ultimately promote transformative social change. 相似文献

In this paper we investigate the possibility of Pareto improving social security reforms within a framework of endogenous
growth. Belan et al. (1998) propose a transition from a pay-as-you-go (PAYG) pension system to a system of savings–subsidization.
We follow this approach and prove that a Pareto improving conversion from the PAYG system to a fully funded one is possible.
Finally, we compare the subsidy system with the fully funded system and discuss the problem of implementing the transition
to the fully funded system.
