Breeding bird communities in Berlin were investigated at five study sites, which represent an structural urban-rural gradient,
from densely built-up areas with sealed ground to green areas such as large parks. In this paper, we tested the Hasse Diagram
Technique (HDT), an approach belonging to partial order theory, for its appropriateness to extract information about changes
in species composition from our data set. As expected, the overall number of bird species was positively correlated with the
urban-rural gradient, increasing from 12 found in the city center to 28 in an urban park. By HDT analysis, four different
sub-groups of birds could be identified, contributing differentially to the increase in species number: (1) ubiquists, i.e.,
species found at each study site, (2) a sub-group, the species’ number of which was positively correlated with the urban-rural
gradient, increasing with increasingly green areas, (3) a sub-group, the species’ number of which was negatively correlated
with the urban-rural gradient, decreasing with a declining density of buildings, and (4) species, the distribution of which
did not show any correlation with the urban-rural gradient. The results show that HDT is a suitable tool for formalized analysis
of the pattern of species’ communities along an environmental gradient. 相似文献

This study demonstrates that a professional journalism background contributes to the credibility evaluations of public relations practitioners in regards to expertness and the capability to meet journalistic values and expectations. However, having a professional journalism background does not necessarily render public relations practitioners any more trustworthy than not having such credentials. 相似文献

Governmental organizations play a major role in disaster relief operations. Supply chains set up to respond to disasters differ dramatically in many dimensions that affect the cost of relief efforts. One factor that has been described recently is self‐sustainment, which occurs when supplies consumed by intermediate stages of a supply chain must be provided via the chain itself because they are not locally available. This article applies the concept of self‐sustainment to response supply chains. A mathematical model of a self‐sustaining response supply chain is developed. Analysis of this model yields insights about the relationships and interactions among self‐sustainment, speed of disaster onset, dispersion of impact, and the cost of the relief efforts. 相似文献

Data on 117 young sexual abusers were examined to investigate the nature of community responses to young people's abusive behaviour. A wide range of community responses were found, with stigmatisation, social isolation and collateral damage being common. A contagion effect was noted, with community responses extending over time and across contexts. Some young offenders and their families were attacked and forced out of their homes. In some cases, community responses heightened risk factors. The policy and practice implications of the findings are discussed, including the need for caution about the inclusion of children in policies on community notification of sex offenders. 相似文献

State Medicaid programs have expanded home and community-based services (HCBS). This article compares trends and variations in state policies for Medicaid HCBS programs in 2005 and 2010. State limitations on financial eligibility criteria and service benefits have remained stable. Although the use of consumer direction, independent providers, and family care providers has increased, some states do not have these options. The increased adoption of state cost control policies have led to large increases in persons on waiver wait lists. Access could be improved by standardizing and liberalizing state HCBS policies, but state fiscal concerns are barriers to rebalancing between HCBS and institutional services. 相似文献

Occupational accidents and injuries continue to be a critical concern for nurses, given the hazardous healthcare environment. This study advances the research on workplace safety by studying the process variables (i.e. job-related negative affect (JRNA) and job satisfaction) in explaining the relationship between safety climate and various safety criteria in nurses. Based on survey data from 326 nurses, our findings suggest that psychological safety climate is negatively related to JRNA, turnover intentions, safety workarounds, and workplace hazards. In addition, structural equation modelling indicated general support for a model in which psychological safety climate influences employee strain through job attitudes, including JRNA and job satisfaction. More specifically, job attitudes were found to mediate the relationship between psychological safety climate and turnover intentions, experience of hazards, and injuries. Safety workarounds did not significantly relate to injuries. The present study contributes to the ongoing improvement of interventions aimed at mitigating nurses’ injuries by integrating job attitudes into the safety climate–safety outcome framework. 相似文献

Where Would I Be Without You, the first and only poetry recording from Olivia Records, offers a glimpse into the powerful friendship and artistic collaboration between poets Pat Parker and Judy Grahn. Grahn and Parker met in Oakland, California in 1970, beginning an artistic collaboration and a powerful friendship that endured through Parker's death in 1989. Grahn's and Parker's work spread the good news of poetry; they were integral to how we lesbians imagined our voices in the world. The articles in this special issue reconsider and pay tribute to their work. 相似文献

This paper examines hiring decision under uncertainty of firing costs. We extend the labor demand problem of the firm to account for a random shock that hits the firing cost function. We also consider recursive preferences for the employer in order to separate risk aversion from intertemporal substitution. We find that a rise of the variance of the shock decreases hiring investment if and only if the intertemporal elasticity of substitution is greater than one. The risk aversion parameter does not determine the sign of the uncertainty effect but only its magnitude. 相似文献
