The paper confronts the German Alliance for Jobs (Bündnis für Arbeit) with the literature about the Bündnis für Arbeit. The common dominator of the literature is its bias to define the Bündnis as an instrument for problem solving on the Geman labor market. Reconstructing the emergence of the Bündnis and the conflict over voluntary retirement benefits to workers at age of 60 (Rente mit 60) the paper argues to analyze the Bündnis from the perspective of politics instead from the perspective of actor’s capacities to solve problems.  相似文献

Life Skill Service Needs: Perspectives of Homeless Youth   总被引:1,自引:1,他引:1  
The present study describes the service needs related to life skill development from the perspective of sheltered homeless youth. Qualitative semistructured life narrative interviews addressing the use of services at an emergency shelter were administered to 30 youth. All youth were residig in an emergency shelter located in a large metropolitan area at the time of interview. Youth identified factors that influence their ability to access and utilize services, categorized as service availability, factors serving as access and/or barriers to services and lack of available services. Youth identify service delivery approaches and staff characteristics as impacting service delivery. Services such as counseling and childcare were identified as facilitating development and acquisition of life skills.  相似文献

Labour markets across industrialised countries have seen an increasing polarisation between insiders and outsiders as a result of labour market deregulation and welfare retrenchment, with governments responding to rising pressure from employers. But where are trade unions in this process of labour market deregulation and dualisation? Insider/outsider as well as producer coalition approaches portray organised labour as a structurally conservative force that is ready to prioritise the interests of insiders at the expense of those at the margins of the labour market. Rather than protecting the entire working class, unions are seen as being “complicit” in labour market dualisation that leaves an ever greater number of workers vulnerable. Our examination of the Korean case, though commonly perceived as an example of unions pursuing particularistic interests, does not comply with this image, but shows greater union inclusiveness in the face of socio-economic and socio-political challenges. Understanding the change in Korean trade union strategies, we highlight the critical importance of union identities shifting towards social movement unionism, in addition to the perceived imperative to revitalise the movement in order to remain a meaningful social force.  相似文献

Short-sentenced (less than 12 months) offenders in the United Kingdom consistently account for the greatest number of discharges from prison and demonstrate the highest risk and rate of reoffending. Moreover, until recent changes in UK legislation in 2015, individuals serving short sentences were released into the community with little support postrelease. The present study presents an exploration of (re)offending in individuals who have already served multiple short sentences in custody and aims to understand their experiences, perceptions, and insight into their offending. Is there anything apropos short sentences specifically, or those who continually serve them, that can explain the high rates of reoffending in this population? Semistructured interviews were conducted with eight prisoners currently serving short custodial sentences. Interpretative phenomenological analysis was implemented deriving three superordinate themes from the rich dataset: (a) living short sentences, (b) “You’d do the same if you were me,” and (c) negotiating an identity.  相似文献

This paper provides a knowledge‐based perspective to understanding public value management (PVM). As distinct from other approaches to public administration, PVM focuses on collaborative capacity building for the creation of public value. To develop the notion of PVM further, we explore the role of a knowledge‐based strategy in a case study of change implementation in 18 disability service organisations in Western Australia. Our findings show important inter‐relationships between knowledge management strategy, adopting a person‐centred approach to service provision, and sustainability of change implementation. We discuss the implications of the study for disability sector change management and for the further exploration of the strategic role of knowledge management capabilities in the study and practice of PVM in public sector administration. The paper explores the relationship between an organisation's knowledge capture and sharing systems and processes and its ability to implement change in a way that generates long‐term benefits for both public sector employees (e.g., engaging with key stakeholders to generate innovative solutions for serving client needs) and clients (i.e., increased well‐being through better service design and support).  相似文献

Transit buses are an integral part of urban life. They reduce externalities generated from private vehicles and increase geographic mobility. However, unlike most private vehicles in the United States, they use diesel fuel and emit higher amounts of toxic pollutants. The U.S. Environmental Protection Agency set emission standards for transit buses starting in 1988 that have been continually updated, but their public health and economic impacts are unclear due to scarce emissions data. I construct a novel panel dataset for the New York City (NYC) Transit bus fleet between 1990 and 2009 and examine the impact of bus pollution on infant health by using bus vintage as a proxy for emissions. I exploit the variation in vintage as older buses are retired and replaced with newer, lower‐emitting buses forced to adhere to stricter emission standards. I then assign maternal exposure to bus vintage at the census block level. Findings suggest that maternal exposure to the oldest, unregulated buses is associated with modest reductions in birth weight and gestational age relative to newer buses that abide by emissions policies. I then conduct a back‐of‐the‐envelope cost‐benefit calculation and find net economic benefits of $53.3 million resulting from improved emission standards for the 2009 birth cohort in NYC. Since the treatment in this study clearly maps to federal emissions policies, these results are the first to provide credible evidence that transit bus emission standards had a positive effect on infant health.  相似文献

In this research note we employ the work of Wiktorowicz who suggests that persons who are knowledgeable of Islam may be more capable of critically evaluating the claims of militant recruiters and ideologues and thus be more resistant to their appeals than those who are not knowledgeable. This gives rise to an interesting research question: Does knowledge of Islam reduce support for Islamist militancy? To evaluate this research question, we employ data derived from a nationally representative survey fielded among 16,279 Pakistanis in 2011. Using several survey items, we construct a “knowledge index” to measure respondents’ basic knowledge of Islam, which is our principal independent variable. To operationalize support for militancy we use two survey items that query respondents about their support for two prominent Islamist militant groups based in and from Pakistan: the Afghan Taliban as well the sectarian group, Sipah-e-Sahaba-e-Pakistan (also known as Lashkar-e-Jhangvi and Ahle Sunnat Wal Jamaat). We use ordinary least squares regression to evaluate the impact of our independent variables upon support for these two groups, controlling for other relevant factors. We find that knowledge of Islam does predict less support for these two groups; however, other variables such as sectarian organization and ethnicity have greater predictive power.  相似文献

This study emphasizes the dimension of complex linguistic links (as is the case in New Brunswick ‐ the only officially bilingual province in Canada) and highlights optimizing conditions connected to deliberative instruments’ engineering, to their implementation and ensuing decision‐making processes. To do so, we mainly focused on elements slowing down those instruments’ efficiency, particularly for public policies development. Two dimensions or success conditions emerge from our analysis: 1) the substantive dimension which relates to the bilingualisation role of the instrument and, 2) the process dimension concerning the issue of referral – the role of the instigator and instrument bearer.  相似文献

Color determination of soil evidence is often done by visual comparison to soil color charts. A handheld spectrophotometer was tested with representative materials for its suitability for forensic soil characterization. Instrumental colorimetry provides accurate colorimetry with ~10-fold better precision than a soil color chart. The minimum sample size for accurate color determination was between 0.02 and 0.04 mg of fine soil for the specific instrument tested. Reporting colors in the L*a*b* space permits quantification of ΔE00, a measure of perceptible color difference, could enable objective quantification of small color differences and thresholds for forensic soil comparisons. A ΔE00 greater than ~ 3.5 to 6 likely indicates disparate soil sources in a forensic comparison, in the absence of confounding factors like sample alteration. Despite the superior precision of instrumental colorimetry, this approach is inappropriate for samples which are mottled at an inseparable scale, attached to a substrate, or too small for instrumental measurement.  相似文献
