Analyses and policy statements about publicly funded services frequently distinguish 'demands' from 'needs'. The distinction has been challenged, calling into question the coherence of formulating welfare policy and evaluating public services in terms of needs. This paper explicates the conceptual distinction between demands and needs in terms of derived demand and information asymmetry. 'Needs' can be defined as 'rational demands', where 'rational' means 'consistent and evidence–based', and 'demands' as 'desires' rather than 'effective (i.e. economic) demand'. On that basis, practical demand management in needs–based public services would require:
1. Knowledge of users' demands for services;
2. Content analyses of users' demands to identify any misinformed demands;
3. Conversion of any misinformed demands into evidence–based specifications of needs;
4. Formulating coherent, evidence–based demands on behalf of users who cannot to do so themselves.
A study of English NHS Primary Care Groups explores the problems which authorities responsible for publicly funded services face in undertaking these activities. Demand management receives low priority in terms of the incentives and intellectual resources applied to it. Needs assessment has higher priority but is regarded as a branch of evidence–based professional practice, controlled by professionals rather than responsive to users. This separation tends to defeat the purposes of needs–based public services.  相似文献

This paper examines multiple characteristics of belief systems among people at different levels in the policy process using the same measures in the same time period. More specifically, it analyzes belief systems concerning the environment among the general public, several attentive publics, and state legislators in Idaho. The following belief system characteristics are probed: horizontal constraint among specific issue beliefs, and between general environmental orientations and party and ideology; vertical constraint between the general environmental orientation and specific issue beliefs; and the role of general orientations in screening incoming information. Legislators are more likely to connect their environmental beliefs to partisan and ideological orientations. However, attentive and general public respondents do exhibit substantial constraintwithin the environmental issue domain; individual self-placement on a preservationist-developmentalist dimension appears to provide a cohering force in orientations to the environment. While legislators exhibit greater belief connections with general political orientations, the results also suggest an order in the public's beliefs about the environment and in the nature of conflict over the environment.  相似文献

Social justice in animals is beginning to attract interest in a broad range of academic disciplines. Justice is an important area of study because it may help explain social dynamics among individuals living in tightly-knit groups, as well as social interactions among individuals who only occasionally meet. In this paper, we provide an overview of what is currently known about social justice in animals and offer an agenda for further research. We provide working definitions of key terms, outline some central research questions, and explore some of the challenges of studying social justice in animals, as well as the promise of the work we're proposing. Finally, we suggest why continued research into animal cognition and social behavior has significant ethical implications for our treatment of nonhuman animals.  相似文献

Online vendors are offering a new legal high, 4‐methylpentedrone (4‐MPD). Information for potential users provided by internet vendors of 4‐MPD includes incorrect structures and nonexistent CAS numbers. A sample of 4‐MPD was obtained and analyzed using GC‐MS, NMR, and LC‐EIS. The fragmentation data from the GC‐MS and LC‐EIS produced an M‐1 ion that suggested the molecular mass was 219 amu, rather than 205 amu as calculated for 4‐methylpentedrone. The difference in molecular mass corresponded to the addition of a methyl group. Based on the mass and fragmentation pattern, two standards were synthesized, 2‐(ethylamino)‐1‐(4‐methylphenyl)‐1‐pentanone and 1‐(4‐methylphenyl)‐2‐(propylamino)‐1‐butanone. The synthesis involved bromination of the appropriate ketone followed by the reaction with ethylamine or propylamine. Based on the NMR data and unique fragmentation patterns produced by these molecules, the sample was identified as 2‐(ethylamino)‐1‐(4‐methylphenyl)‐1‐pentanone, not 4‐methylpentedrone.  相似文献

In this paper we seek to assess the effects of the neighborhood context on sex offenders’ perceptions of their neighbor’s willingness to support them upon release. We also examine the effect of the neighborhood context on sex offenders’ feelings of stress and the need for secrecy, potential risk factors for recidivism. Using survey data obtained from a sample of 333 in-treatment sex offenders, we find that the neighborhood social context exerts an important influence on sex offenders’ perceptions of neighborhood support. We also find that offenders are less likely to worry about the negative repercussions of their status as a sex offender when they perceive higher levels of neighborhood support. Despite the limitations of the sample, implications of this research indicate a need for policies that promote public awareness of local sex offenders while also offering education and understanding about potential barriers to successful sex offender reintegration.  相似文献

The first synthesis of the 2,3-isomers of MDPV, butylone and methylone is reported. The isomers were characterised by (1)H and (13)C NMR spectroscopy and compared to the corresponding 3,4-isomers. A GC method is described which separates the 3,4- and the 2,3-isomers from each other. IR spectra of the 2,3-isomers are also compared with the corresponding 3,4-isomers. Two seized drug samples were analysed by GCMS and the samples were found to contain the 3,4-isomers.  相似文献

A growing number of U.S. cities have large numbers of untested sexual assault kits (SAKs) in police property facilities. Testing older kits and maintaining current case work will be challenging for forensic laboratories, creating a need for more efficient testing methods. Methods: We evaluated selective degradation methods for DNA extraction using actual case work from a sample of previously unsubmitted SAKs in Detroit, Michigan. We randomly assigned 350 kits to either standard or selective degradation testing methods and then compared DNA testing rates and CODIS entry rates between the two groups. Results and conclusions: Continuation‐ratio modeling showed no significant differences, indicating that the selective degradation method had no decrement in performance relative to customary methods. Follow‐up equivalence tests indicated that CODIS entry rates for the two methods could differ by more than ±5%. Selective degradation methods required less personnel time for testing and scientific review than standard testing.  相似文献
