Research on and practical attention for the coproduction of public services is increasing. Coproduction is seen as a way to strengthen the quality and legitimacy of public service and reduce costs. Scholarship on coproduction of public services repeatedly ignores the role of the new media. This is surprising since many proponents highlight its potential for changing traditional, government‐centric approaches to delivering public services. This article shows that digital communities form an important addition to the government‐centric form of public service provision since they foster both an exchange of experiential information and social‐emotional support. 相似文献

This article discusses recent legal conflicts between state universities and conservative religious students in the United States, focusing on Christian Legal Society v. Martinez. In recent years, several universities have denied recognition to religious student organizations that discriminate on the basis of religion or sexual orientation. I argue that scholars on both sides of the issue have failed to recognize the full scope of the privilege that the universities demand. If the courts accept the universities' demands, then the courts dangerously expand the government's authority to suppress dissenters. No proponent of civil liberties should welcome this change. 相似文献

The present postmortem study examines whether specific amino acid abnormalities associated with renal diseases or diabetes mellitus in animal experiments and on clinical examination may also be found in human brain samples obtained at clinical autopsies. The material includes 12 deceased with renal insufficiency, 23 deceased with diabetes mellitus and 26 control cases with lethal cardiovascular diseases (without a history of hepatic, renal or metabolic disturbances). The autopsy and clinical records were retrospectively analyzed for age, sex, postmortem delay, cause of death, substantial preexisting diseases and histological findings. The analysis of free amino acid concentrations in human brain specimens was performed applying a Beckman amino acid analyzer. The results were evaluated using the U-test according to Mann, Willcox and Whitney. A P-value less than 0.05 was considered to be significantly different. Differences of amino acid concentrations attributable to sex, age and postmortem delay were not significant. The comparison of postmortem amino acid concentrations in the brains of patients with diabetes mellitus and controls did not reveal relevant changes. However, the patients with renal diseases, as compared to controls, showed a significant cerebral increase of urea, phenylethanolamine and gamma-aminobutyric acid. Thus, the postmortem amino acid analysis may contribute to the understanding of pathophysiological mechanisms of uremic encephalopathy and may supplement the conventional postmortem morphological diagnosis in kidney diseases by indication of functional impairment. 相似文献

The central hypothesis of the economic model of voter participation was put to an empirical test. It was found that the coefficient of population size, which represents the subjective probability of affecting election results, is negative and significant in municipal local elections, but insignificant in national Knesset elections. Therefore, this variable is unable to represent subjective probability in the latter case.It was suggested that the economic model is more relevant to local elections than to Knesset elections. The empirical results revealed that the regression coefficients of municipal elections that took place separately from Knesset elections fit the expected outcome of the economic model whereas when municipal elections were held simultaneously with the Knesset election this did not hold true. 相似文献

The purpose of this article is to examine the evolution of Israel's relations with Saudi Arabia since the establishment of the Jewish state in 1948. The author explains how the major events in the Middle East affected Saudi Arabia's foreign policy orientation. It shows how Saudi Arabia's policy toward Israel was affected by the deterioration in Saudi-Egyptian relations, by its quest for security in the Arabian Gulf region and by its aspiration to hegemony in the Middle East. The author argues that Saudi Arabia's policy toward Israel remained far less hostile than that of the Arab states surrounding Israel. In addition, it argues that it was not until 1973 that Saudi Arabia became seriously involved in the attempt to pressure Israel to withdraw from the territories it occupied in the Six-Day War. The author concludes by showing that neither Saudi Arabia's acquisition of the intelligence-gathering AWACS aircraft, nor Israel's invasion of Lebanon or the massacre of Palestinians in the refugee camps of Sabra and Shatila had a serious impact on the bilateral relations, and that it was not until the emergence of the Iranian nuclear threat that Saudi Arabia's relations with Israel began to improve. 相似文献

In principle, experiments offer a straightforward method for social scientists to accurately estimate causal effects. However, scholars often unwittingly distort treatment effect estimates by conditioning on variables that could be affected by their experimental manipulation. Typical examples include controlling for posttreatment variables in statistical models, eliminating observations based on posttreatment criteria, or subsetting the data based on posttreatment variables. Though these modeling choices are intended to address common problems encountered when conducting experiments, they can bias estimates of causal effects. Moreover, problems associated with conditioning on posttreatment variables remain largely unrecognized in the field, which we show frequently publishes experimental studies using these practices in our discipline's most prestigious journals. We demonstrate the severity of experimental posttreatment bias analytically and document the magnitude of the potential distortions it induces using visualizations and reanalyses of real‐world data. We conclude by providing applied researchers with recommendations for best practice. 相似文献
