The National Oceanic and Atmospheric Administration instituted a Planning, Programming, Budgeting, and Execution System (PPBES) in 2002. As supplemented by matrix management, PPBES was appealing as an effort to rationalize the performance of an agency with an especially high degree of functional overlap among its component parts. Although PPBES has had some salutary effects, the agency's experience to date consistent with accounts of the difficulties that led to the abandonment of program budgeting by the civilian bureaucracy almost 40 years ago. As such, it speaks to the limits of performance assessment as a means of reallocating resources and responsibilities across organizational boundaries.  相似文献

The effects of polls on public opinion and voting behavior have begun to attract considerable attention. However, aside from experimental studies and research on exit polls, the impact of preelection polls has not received adequate analysis. This paper investigates whether exposure to polls released during the campaign influences voter choices and how the electoral context of referendum versus candidate elections makes a difference in terms of polling effects. These questions were addressed in a cross-election comparison of the 1980 presidential campaign and a 1986 state referendum on the right-to-life issue. Basically, I found significant effects during the referendum, but weak effects in the presidential general election.  相似文献

We studied the biomechanical behaviour of ring and strip specimens from along the length of 18 vertebral arteries taken from 16 subjects aged 28-90 years, in order to consider some of the factors which may play a role in vertebral artery rupture. The method was chosen to allow a comparison between circumferential distension (ring samples) and longitudinal extension, (strip samples). The samples were extended between the jaws of a tensile testing apparatus until the specimen broke and a number of biomechanical parameters were derived. These were the percentage extension to break, the tensile strength, Young's modulus and the peak load. There were a number of important findings. The vertebral artery was shown to be susceptible to longitudinal stretching with a number of strip samples breaking when extended by as little as 16-20%. The tensile strength and load at peak of the strip specimens were correspondingly lower than for the ring samples. Marked intersubject variations were shown for all these parameters and prominent changes in behaviour occurred along the vertebral artery. This study indicates that the artery may be susceptible to head and neck movements which cause the vessel to stretch, and intersubject variations in behaviour may be one important explanation for the marked differences in outcome which appear to exist in subjects who suffer broadly similar head and neck insults.  相似文献

This paper describes an effort to develop a clinical tool for the continuous monitoring of risk for violence in forensic mental health clients who have left their institutions and who are dwelling in the community on a conditional release basis. The model is called Structured Outcome Assessment and Community Risk Monitoring (SORM). The SORM consists of 30 dynamic factors and each factor in SORM is assessed in two ways: The current absence, presence or partial och intermittent presence of the factors, which is an actuarial (systematized and 'objective') assessment. Secondly, the risk effect, i.e. whether the presence/absence of factors currently increases, decreases or is perceived as unrelated to violence risk, is a clinical (or impressionistic) assessment. Thus, the factors considered via the SORM can be coded as risk factors or protective factors (or as factors unimportant to risk of violence) depending on circumstances that apply in the individual case. Further, the SORM has a built-in module for gathering idiographical information about risk-affecting contextual factors. The use of the SORM and its potential as a risk monitoring instrument is illustrated via preliminary data and case vignettes from an ongoing multicenter project. In this research project, patients leaving any of the 9 participating forensic hospitals in Sweden is assessed at release on a variety of static background factors, and the SORM is then administered every 30 days for 2 years.  相似文献

Black women and intimate partner violence: new directions for research   总被引:1,自引:0,他引:1  
African American women are at elevated risk for nonfatal and lethal intimate partner violence (IPV). Accordingly, the purpose of this article is to review our current knowledge, with a focus on the sociodemographic factors that make this population particularly vulnerable to abuse. Future research directions include using more diverse Black samples, considering how living at the intersection of multiple forms of oppression shapes Black women's experience with violence, exploring the influence of historical events and oppressive images on victimization, and focusing on survivors' resilience and activism.  相似文献
