Histological analysis of bone tissue has been used to explore a variety of questions relating to age-at-death, habitual behaviors, health, and nutritional stress. Identification of intact and fragmentary osteons is of key interest to many researchers in these studies, yet the definitions of these features vary between researchers making cross-study comparisons problematic. Furthermore, histological variable definitions are often ambiguous or require subjective classifications by the observer. As a result, and as indicated by previous studies, observer error and misclassification of certain variables, namely intact and fragmentary osteons, can be significant. This study proposes new definitions for intact and fragmentary osteons that are designed to limit observer subjectivity and also explore efficacy of combining osteon types into one variable. A sample of 30 6th rib cross-sections from a modern forensic population was used to test the validity of the proposed definitions. Observations of intact osteon population density (OPD(I)) and fragmentary osteon population density (OPD(F)) were made by three observers for each cross-section. These observations were used to explore the interobserver error associated with the proposed definitions and determine if combining variables into one variable (OPD) mitigates persisting classification difficulties. Results indicate that the proposed definitions significantly reduce interobserver error and misclassification of intact and fragmentary osteons. However, the interobserver error associated with fragmentary osteons is still high. Evaluation of the variables independently indicates that combining variables has potential to reduce the predictive strength of an age estimation model and the ability to interpret age-related bone remodeling. 相似文献

As performance‐based contracting in social welfare services continues to expand, concerns about potential unintended effects are also growing. We analyze the incentive effects of high‐powered, performance‐based contracts and their implications for program outcomes using panel data on Dutch cohorts of unemployed and disabled workers that were assigned to private social welfare providers in 2002 to 2005. We employ a difference‐in‐differences design that takes advantage of the fact that contracts gradually moved from partial performance‐contingent pay to full (100 percent) performance‐contingent contracting schemes. We develop explicit measures of selection into the programs and find evidence of cream skimming and other gaming activities on the part of providers, but little impact of these activities on program outcomes. Moving to a system with contract payments fully contingent on performance appears to increase job placements, but not job duration, for more readily employable workers. 相似文献

While research on the distinctions between for‐profit and nonprofit organizations and their changing service sector shares is vast, there is comparatively little empirical evidence on the consequences of their differing attributes for social program outcomes. This article presents research on publicly subsidized for‐profit and nonprofit job‐training service providers, namely whether organizational form influences client enrollment, service delivery activities, or performance, as measured in terms of participant outcomes. The findings show that nonprofit providers were not more likely to serve more disadvantaged clients and that neither for‐profit nor nonprofit service providers were consistently more effective in increasing participants' earn‐ings and employment rates. When performance incentives were included in service providers' contracts, contractors of all forms performed significantly better across all participant outcomes examined. © 2000 by the Association for Public Policy and Management. 相似文献

Despite the wide‐ranging use of performance measures within the public sector and the growing use of performance bonuses to recognize performance achievements, the use of formal performance standards adjustment procedures in public performance measurement systems is relatively rare. Burt S. Barnow of Johns Hopkins University and Carolyn J. Heinrich of the University of Wisconsin–Madison set forth the basic arguments in favor of and against the use of formal or informal procedures for adjusting performance expectations. They describe how performance standards adjustments processes are currently (or have been) in use, review the evidence of their effectiveness or problems encountered in their application, and explore the consequences of the inadequacy of performance standards adjustments. The authors offer recommendations for the improvement of public sector performance measurement systems and conclude why this area remains fruitful for future research experimentation. The nice thing about standards is that there are so many of them to choose from. —Andrew S. Tannenbaum 相似文献

The impact of globalization on the composition of government expenditures: Evidence from panel data 总被引:1,自引:0,他引:1
According to the disciplining hypothesis, globalization restrains governments by inducing increased budgetary pressure. As a consequence, governments may attempt to curtail the welfare state, which is often seen as a drag on international competitiveness, by reducing especially their expenditures on transfers and subsidies. This globalization-induced welfare state retrenchment is potentially mitigated by citizens’ preferences to be compensated for the risks of globalization (“compensation hypothesis”). Employing two different datasets and various measures of globalization, we analyze whether globalization has indeed influenced the composition of government expenditures. For a sample of 60 countries, we examine the development of four broad expenditure categories for the period 1971–2001: capital expenditures, expenditures for goods and services, interest payments, and subsidies and other current transfers. A second dataset provides a much more detailed classification: public expenditures, expenditures for defence, order, economic affairs, environment, housing, health, recreation, education, and social expenditures. However, this second data set is only available since 1990—and only for OECD countries. Our results show that globalization did not influence the composition of government expenditures in a notable way. 相似文献

This paper examines the influence of political propaganda on voters and analyses the behavior of the interest groups in the face of the influence being exercised. By propaganda semitruths are distributed among the electorate. The decision taken by a voter results from his basic opinion and from the parts of information he receives. The analysis shows that the greater the likelihood of a certain decision being reached by a fully informed electorate, the more probable it is that the same decision will be reached by a rationally uninformed electorate. The pecuniary interest of an interest group is, however, also positively correlated with the probability that the electorate reaches a decision which is agreeable to that interest group. It has finally become apparent that the results of the approach concur well with empirical studies. 相似文献

A collaborative study was carried out by the European DNA Profiling Group (EDNAP) in order to evaluate the performance of Y-chromosome binary polymorphism analysis in different European laboratories. Four blood samples were sent to the laboratories, to be analysed for 11 Y-chromosome single nucleotide polymorphisms (SNPs): SRY-1532, M40, M35, M213, M9, 92R7, M17, P25, M18, M153 and M167. All the labs were also asked to submit a population study including these markers. All participating laboratories reported the same results, indicating the reproducibility and robustness of Y-chromosome SNP typing. A total of 535 samples from six different European populations were also analysed. In Galicia (NW Spain) and Belgium, the most frequent haplogroup was R1b*(xR1b1,R1b3df). Haplogroup F*(xK) is one of the most frequent in Austria and Denmark, while the lowest frequency appear in Belgium. Haplogroup frequencies found in this collaborative study were compared with previously published European Y-chromosome haplogroup data. 相似文献
