Publishing performance information about local public services,an increasing trend in many Organisation for Economic Co-operationand Development countries, matters politically because it hasan effect on incumbent local governments' electoral support.Voters are able to use performance information to punish orreward incumbents in the elections that follow their publication,which may fill a gap in the chain of accountability betweenvoters and governments. We model the introduction of publishedComprehensive Performance Assessments of local authorities inEngland, which make summary information about performance availableto voters, as a "shock" to the relationship between voters andincumbents. Controlling for an unpublicized measure of performancechange over time, change in the local tax level, change in localeconomic conditions, and whether the local incumbent is theparty of the incumbent government at the national level, wefind negativity bias. Incumbents in local authorities in the"poor" performance category experience a substantial reductionin aggregate vote share at the election following publication,but there is no similarly sized reward for those in the highestperformance category. 相似文献

Much of the current knowledge pertaining to information technology (IT) and decision making is based on decades old technologies that revolved around a central computing function and application-specific systems. The purpose of this research is to examine the IT decision-making relationship within the emerging organizational computing (OC) environment permeated by spontaneous utilization of both application-and nonapplication-specific computing and communication technologies. Specifically, this study seeks to explore managers' perceptions of the emerging OC environment as a facilitator of their decision-making activities. To achieve a higher level of clarity than previous works, a two-dimensional research framework is developed with the IT dimension consisting of computing and communication, and the decision-making dimension differentiated between operational and managerial decisions. A survey instrument was constructed that measured the computing and communication dimensions of information technology use and their perceived effects upon operational and managerial decisions. The major findings of the study confirmed that managers recognize the value of general, nonapplication-specific information technologies in decision making, and that this recognition is highly associated with how intensively these information technologies are used. Additionally, it was found that the two dimensions of IT differ in their relationships to decision making, and that IT usage relates to managerial decisions differently than operational decisions. These study findings have significant implication for practice and research, especially in the context of information resource management in which the primary purpose of the IS function is the delivery of general information service to users rather than the development of specific IS applications. 相似文献

Caleb Perry Patterson was a leader in the discipline of political science during a long career. He is remembered as the founder of the national political science honor society, Pi Sigma Alpha, and as a charter founder of the Southwestern Political Science Association (now the Southwestern Social Science Association). Both were founded a century ago, in 1920. While his role in founding those organizations is one of his legacies, his career was much more than that. He was a notable educator, an activist in the politics of his time, and a prolific scholar. He used an oratorical presentation style to inspire generations of students, and through promotion of constitutional values, he encouraged independence of thought. One prominent Texas political observer summed up his impact as encouraging students of all political stripes to “love the thing that is America” and to provide critical thinking during the McCarthy Era. With Patterson as his reference, he concluded that “the only thing that can save us is the professors, really.” 相似文献

Decisions to Outsource Information Systems Functions: Testing a Strategy-Theoretic Discrepancy Model
In recent years, the decision to outsource information systems (IS) functions has become a viable strategic alternative in managing the increasingly complex IS functions. In this study, the IS outsourcing phenomenon is conceptualized as a strategic decision in the organization. Drawing on resource-based theories, resource dependence theories, and other theories of strategic management, a discrepancy model of this decision is developed. Relationships between a number of strategy-theoretic factors and the IS outsourcing decision are hypothesized. These factors include IS resource performance discrepancies manifested in the form of gaps in information quality, IS support quality, IS cost effectiveness and financial performance, as well as the strategic orientation of the firm. Results of the study indicate that, while cost consideration and the firm's financial performance are not associated with the IS outsourcing decision, difficulties in providing good information outputs and IS support services are associated with the decision. Overall, the findings suggest that the current trend toward outsourcing represents a continuing evolution of the IS function as it attempts to fulfill its traditional mission of providing high quality information resource to the firm. When the performance of the delivered resource begins to slip in the current environment of rising expectation and technological complexity, outsourcing may become a strategic response of necessity. The paper concludes with a discussion of the implications of the results for practicing managers and suggestions for future research. 相似文献

Product bundling has become increasingly prevalent not only in consumer goods but also in the industrial sector. We study a purchasing problem in which a buyer must obtain necessary numbers of various stock items from a variety of vendors who charge different prices, have limited capacities and different levels of quality, and offer bundled products at discounted prices. We examine relationships among different bundling scenarios and show that the most general scenario is one in which free items are given to the buyer when sufficient quantities are purchased. We develop a mixed integer linear program that finds the purchasing strategy for the buyer that minimizes the total purchase cost. We present computational results which indicate that the problem is very tractable to solve optimally on a personal computer with standard optimization software. Finally, three extensions of the model are discussed. 相似文献
