Abstract

Goals in the public sector are complex and managers can face situations in which pursuing one legitimate goal necessitates performance trade-offs in other areas. This study tests how knowledge of legitimate performance trade-offs shapes the perception of red tape. Using a vignette experimental design and a sample of university students, between group t-tests and regression analyses suggest that, when evaluating increased rule burden, individuals that are provided with information about how objectively burdensome rules serve alternative values such as equity and effectiveness associate them with lower levels of red tape. A series of Monte Carlo simulations suggest that this effect is substantial.  相似文献

The social development model (SDM) is a theory of behavior that has proven useful in explaining the etiology of delinquency, violence, and substance use among adolescents as well as early antisocial behavior among pre-adolescents. A further test of the model is its generalizability across population groups. A section of the SDM representing prosocial influences in the etiology of problem behavior was compared for boys and girls and for children from low- and non low-income families using three waves of child, parent and teacher survey data on a sample of 851 elementary school students. Multiple group structural equation modeling was used to assess differences across groups in both measurement of model constructs and hypothesized structural paths between constructs. The results indicate overall similarity in the reliability of measurement models and validity of structural models.  相似文献

This article explains political radicalism by the number of voters who are biased towards a party. With little voters biased in favor of a party, this party has to rely more heavily on its programmatic distance to other parties. Because large parties – i.e.: parties with a high number of biased voters – gain votes when they move to the center of the political spectrum, parties with a lower number of voters that are biased in their favor are forced to the edges of the policy space. We draw on a computational model of political competition between four parties in a two‐dimensional policy space to investigate this relationship. We use panel corrected OLS estimates to analyze the data generated by the computer simulation. Our results substantiate the hypothesis of a negative relationship between the number of biased voters and the inclination of a party to adopt a more extreme policy stance.  相似文献

Do parties change their platform in anticipation of electoral losses? Or do parties respond to experienced losses at the previous election? These questions relate to two mechanisms to align public opinion with party platforms: (1) rational anticipation, and (2) electoral performance. While extant work empirically tested, and found support for, the latter mechanism, the effect of rational anticipation has not been put to an empirical test yet. We contribute to the literature on party platform change by theorizing and assessing how party performance motivates parties to change their platform in-between elections. We built a new and unique dataset of >20,000 press releases issued by 15 Dutch national political parties that were in parliament between 1997 and 2014. Utilizing automated text analysis (topic modeling) to measure parties’ platform change, we show that electoral defeat motivates party platform change in-between elections. In line with existing findings, we demonstrate that parties are backward-looking.  相似文献

In the debate on minimal media effects and their causes, methodological concerns about measurement are rarely discussed. We argue that even in state-of-the-art media-effects studies that combine measures of media messages and media use (i.e., linkage analyses), measurement error in both the media content analysis and the media use self-reports will typically lead to severely downward-biased effect estimates. We demonstrate this phenomenon using a large Monte Carlo simulation with varying parameters of the content analysis and the survey study. Results show that measurement error in the content analysis and media use variables does indeed lead to smaller effect estimates, especially when the media messages of interest are relatively rare. We discuss these findings as well as possible remedies and implications for future research.  相似文献

A massive open online course (MOOC) entitled “Shaping the Future of Work” (offered through MITx, the Massachusetts Institute of Technology's online learning division) has been the context for a multiparty simulation designed to produce classroom negotiation results that will have social impacts. After running the course in the MOOC context three times and in face‐to‐face settings eight times, we noticed that key themes emerged. Participants have brought their own workforce perspectives to their simulation roles as employers, worker representatives, elected officials, and educators. They have called for reciprocal agreements centered on fair treatment and representation in the workplace, improved organizational performance, investments in skills and capabilities, aligned rewards and benefits for workers, and work–life balance in communities. We continue to use the simulation in the classroom and are exploring ways to expand its use. In the meantime, in this article, we discuss how the insights gleaned from this simulation could be used to crystallize and advance a new social contract at a time when the public policies, institutions, and organizational practices governing employment relations have not kept up with the dramatic changes taking place in the workforce, nature of work, and overall economy.  相似文献

The horizontal displacement of the human body resulting from fatal fall from a height is an important variable commonly used to inversely determine the cause or identify other forensic aspects of the fall. When examining the horizontal displacement, the wind effect is generally ignored. This technical note reports analytical modeling of the falling process, utilizing previous measurements of wind force acting on the human body, for determining the functional relationship between the wind speed and the horizontal displacement in the falling process. The result reveals that it does not take extremely rare wind conditions to cause a considerable shift of the human body, highlighting the importance to consider wind as a factor in investigations of fatal falls.  相似文献
