Abstract

This article analyses party strategies during the campaign for the Dutch general election of March 2017, making use of issue-yield theory. It investigates whether parties strategically emphasise high-yield issues, by juxtaposing the issue opportunities provided by voters with parties’ issue emphasis during the campaign. More specifically, it asks whether parties strategically emphasised issues that were expected to reward them electorally. Analysing voter preferences and party campaign data, it is found that parties and most of their constituencies show high ideological consistency, that parties emphasise mostly positional issues and thus choose a conflict-mobilising strategy, and that most parties emphasise high-yield issues rather than following the general political agenda. Four small parties that won significantly behaved strategically while the social democrats – who severely lost – hardly did. The findings imply that the issue-yield framework can help to explain the election result in the fragmented Dutch multi-party context.  相似文献

Food handlers are essential in the fight for the prevention of foodborne disease outbreaks as they are critical in ensuring the delivery of safe and healthy food to the consumers. The current study build on knowledge, attitude, and practice model (KAP) to investigate the impact of food handlers' knowledge and attitude on the hygienic‐sanitary conditions of food delivered to the consumers in Nigerian hospitality sector. Using data collected from food handlers in restaurants, hotels and hospitals in Jos metropolis of Nigeria, the study revealed that handlers applied food safety measures to the level of their knowledge. Further investigation revealed that KAP model works effectively in the case of food handlers in Jos. We conclude with recommendations for the industry and education institutes where handlers are trained.  相似文献

Both China and India are adopting information and communication technologies to facilitate openness and transparency in their governments, and hence reduce corruption. Distinctive from their traditional anticorruption approaches, is the innovative e-government approach an effective solution to corruption in these two large developing countries? This paper addresses the question through comparative in-depth interviews with 44 mid- or senior-level officials in the public sector in these two countries. The first study of its kind, our research shows that civil servants in both countries overall think positively about transparency and technology in reducing corruption. However, to what extent these innovative measures will be effective is conditional on various factors, such as political willingness, income inequality, and infrastructure readiness. What is worth noting is that the Chinese respondents were more positive regarding the role of transparency, whereas the Indian respondents were more positive about the role of technology, which may reflect the different facilitators of corruption and the constraints of anticorruption in China and India.  相似文献

Developing nations demand a different scholarly approach in the field of public administration. We advance an agenda for research that stands on four pillars. First, in the absence of easily accessible data scholars of developing world public administration must assemble it for themselves. Second, building and testing theory plays a paramount role because researchers face limited information. Third, in developing countries, multi‐national and non‐governmental organizations are often crucial and must be considered in studying public administration. Fourth, given the novelties and ambiguities researchers face, qualitative information must be integrated throughout the research process. Our article—and the articles in this volume—constitute a call for developing country research to contribute to the study of public administration writ large, informing our understanding of both developing and developed states.  相似文献

Amidst calls for more scrutiny of the failure of infrastructure public–private partnerships (PPPs), uncertainty about how we can measure failure remains, and little systematic evidence illuminates its likelihood. Our mixed‐methods design explores the notion of failure and identifies the conditions under which it happens. The first phase of our research employs documentary analysis and semistructured expert interviews, and identifies project cancellation as capturing the most severe occurrences of failure. A second phase statistically analyzes a unique World Bank data set capturing the provisions of over 4,000 infrastructure PPPs launched between 1990 and 2015 in 89 countries. We find robust evidence supporting the theoretical claim that PPPs are less likely to be canceled in countries with more veto points among their political institutions to restrain politicians from intervening in policy implementation. Cancellation is a rare, but valid indicator of failure, and the importance of veto players clarifies how political risk operates in this context.  相似文献

Certified aircraft mechanics represent the largest gender-based demographic disparity in aviation with a 49-to-1 male-to-female ratio. Recent research into women’s perspective on the aircraft mechanic career field revealed that a large majority of women felt unsure or negatively about their potential promotion opportunities and social acceptance. The purpose of this follow-on mixed-methods concurrent triangulation study was to explore the perspectives of men regarding the aforementioned topics to see if they differ from previously published research on women perceptions. A total of 587 men and 431 women completed an eight-question survey containing 5-point Likert-type and open-ended questions. The quantitative comparison consisted of the total 1018 responses, while only the survey responses from the 587 men were analysed for correlations and qualitative codes. Results indicated that there was a significant difference between the perceptions of men from those of the women regarding work environment safety and social acceptance. Additional correlation analysis revealed social acceptance to be a key variable when predicting career appropriateness, advancement opportunity and work environment safety. The 587 qualitative responses yielded results that differed from those of women, citing an assumption that women have the same advancement opportunities or be as socially accepted as men entering the field.  相似文献
