This article examines the influence of citizen participation, specifically voter turnout, on congressional policy responsiveness. We argue that higher levels of citizen participation signal to representatives greater surveillance of their actions by their constituents and, thus, a higher probability of sanction. Representatives respond to these signals by deploying resources in ways that provide better intelligence of district needs and preferences. As a consequence, higher citizen participation is rewarded with enhanced policy responsiveness.  相似文献

Examining data on the recent health care legislation, we demonstrate that public opinion polls on health care should be treated with caution because of item nonresponse--or "don't know" answers--on survey questions. Far from being the great equalizer, opinion polls can actually misrepresent the attitudes of the population. First, we show that respondents with lower levels of socioeconomic resources are systematically more likely to give a "don't know" response when asked their opinion about health care legislation. Second, these same individuals are more likely to back health care reform. The result is an incomplete portrait of public opinion on the issue of health care in the United States.  相似文献

How are relationships between corporate clients and law firms evolving? Drawing on interview and survey data from 166 chief legal officers of S&P 500 companies from 2006–2007, we find that—contrary to standard depictions of corporate client‐provider relationships—(1) large companies have relationships with ten to twenty preferred providers; (2) these relationships continue to be enduring; and (3) clients focus not only on law firm platforms and lead partners, but also on teams and departments within preferred providers, allocating work to these subunits at rival firms over time and following “star” lawyers, especially if they move as part of a team. The combination of long‐term relationships and subunit rivalry provides law firms with steady work flows and allows companies to keep cost pressure on firms while preserving relationship‐specific capital, quality assurance, and soft forms of legal capacity insurance. Our findings have implications for law firms, corporate departments, and law schools.  相似文献

Despite the increase in media attention on "meth cooking" in rural areas of the United States, little is known about rural stimulant use, particularly the criminality associated with stimulant use. Data were collected from community stimulant users in rural Ohio, Arkansas, and Kentucky (N=709). Findings from three logistic regression models indicate that younger stimulant users (x =32.55, SD = 10.35), those with more convictions, and those who used crack frequently were significantly more likely to have been arrested for committing a substance-related crime, a property crime, or another crime in the 6-months before entering the study. Implications include the need for longitudinal studies to further understand rural stimulant use as well as increasing community and corrections-based drug abuse prevention and treatment interventions for stimulant users who live in rural areas.  相似文献

Dermestidae could be useful in forensic investigations to assess the PMI as adults and larvae colonize dried remains. We reared two species of Dermestidae (Dermestes frischii and Dermestes undulatus) to understand the effects of different temperatures on the length of their whole life cycle and on their immature stages. Both species were reared at 23°C ± 0.5, RH 75% and at 26°C ± 0.5, 75% RH. Our result shows that the temperature is the main factor that influences the development of those species; in fact, increasing temperature leads to a shorter development cycle (59.8 ± 0.5 and 38.1 ± 0.2 for D. frischii; 50.6 ± 0.6 and 36.2 ± 0.2 for D. undulatus). Furthermore, we found that the number of the molts before the pupa decreases from 5–7 to 5–6 for D. frischii and from 4–6 to 4–5 for D. undulatus, respectively, at 23°C and 26°C.  相似文献

The morphological analysis of stab wounds may often not be accurate enough to link it with the type of wounding weapon, but a further evaluation may be performed with the search for metallic residues left during the contact between the instrument and the skin. In this study, Scanning Electron Microscopy-Energy Dispersive Spectroscopy (SEM-EDS) was applied to the study of cadaveric stab wounds performed with kitchen knives composed of iron, chromium and nickel, in order to verify the presence of metallic residues on the wound's edge. Two groups of 10 corpses were selected: group A, including victims of stab wounds and a control group B (died of natural causes). Samplings were performed on the lesions and in intact areas of group A, whereas in group B sampling were performed in non-exposed intact skin. Samples were then analysed with optical microscopy and SEM-EDS. In group A, optical microscopic analysis showed the presence of vital haemorrhagic infiltration, while SEM-EDS showed evidence of microscopic metal traces, isolated or clustered, consisting of iron, chromium and nickel. Moreover, in two cases organic residues of calcium and phosphate were detected, as a probable sign of bone lesion. Control samples (group A in intact areas and group B), were negative for the search of exogenous material to optical microscopy and SEM-EDS. The results show the utility and possible application of the SEM-EDS in theidentification of metallic residues from sharp weapons on the skin.  相似文献

The past year has seen a global upsurge of violent attacks by lone, mentally unstable individuals. The motivations for these attacks have varied and extremist ideological drivers are rarely ‘pure’, but mental health problems and personal grievances are common themes. Mentally ill and disenfranchised individuals may be vulnerable to extremist messages and propaganda because such beliefs can be a means of interpreting their social difficulties. Terrorist messages can also be adopted by psychotic people who are seeking to make sense of their symptoms. Most lone-actor attacks are preventable, if there is a system in place for identifying and intervening with antecedent behaviours, which include mental disturbances and the social problems that frequently accompany these conditions. Joint police-mental health models developed to assess and manage fixated persons can be applied to other forms of grievance-fuelled, lone-actor violence. This paper describes the establishment of such a service in Australia, and provides some preliminary data. It also discusses the role of mental health in the current security environment.  相似文献

One of the most important contributions of forensic entomology is to assist criminal expertise to determine the postmortem interval, which depends on the duration of the immature stages of insects of forensic interest. On the other hand, the time of development of the different stages varies according to the species; therefore, its identification is essential. Currently, few studies have investigated the use of cuticular hydrocarbons, and none regarding fatty acids, as complementary taxonomic tools to expedite species identification. Therefore, we evaluated whether cuticular hydrocarbons together with fatty acids of eggs of flies of the family Calliphoridae, main group of forensic interest, can be used to distinguish species. The analyses were performed by chromatographic techniques. The results show that there are significant differences between the composition of cuticular hydrocarbons and fatty acids between species and, therefore, they can be used to provide a complementary taxonomic tool to expedite the forensic expertise.  相似文献
