Reforming the public sector has been on the agenda of nations throughout the world since the late 1970s. Fiji is no exception. It has embarked on reforming its commercial and industrial enterprises since the late 1980s. The government of Fiji has reformed most of its enterprises with an avowed objective of enhancing profitability, productivity, efficiency and accountability. This paper makes an attempt to share some of the experiences of public enterprise reform process in Fiji. It aims to analyze the background, process, contents and impact of the reform and examine the factors impeding the reform program. It highlights that (a) both internal and external factors were responsible for introducing reforms; (b) the reform efforts have not been able to produce desired results; (c) the structural inadequacies in institutions and organizations have created bottlenecks in the reform process; and (d) uncertainty in the political sphere has contributed further to policy shifts. 相似文献

在全面推进乡村振兴的大背景下,乡村建设正如火如荼地开展。其中,乡村建设中农民房屋建筑类型从特质性的“匠心独具”到同质性的“千村一面”,再到异化性的“自厝同异”变迁路径,反映出传统文化的保护危机,也深刻揭示出建筑变迁背后暗藏的农民与地方政府间的多元矛盾和博弈。此问题的根源在于农民主体性被消解,成了被建构的对象或客体,而地方政府却不断强化构建主体的身份认同。事实上,当前乡村建设呈现出五种不同的价值取向:一是为城市消费者休闲情趣的乡村建设;二是为城市中产阶级家乡情感的乡村建设;三是为地方政府凸显政绩的乡村建设;四是为开发商投资回报的乡村建设;五是为农民生存利益的乡村建设。不同参与者均带着不同的利益诉求介入乡村建设,直接影响到乡村建设的发展走向。因此,要处理乡村建设中的矛盾和问题,必须强化农民在乡村建设中的主体意识和主体身份,赋予农民对乡村建设事务的话语权与决定权。 相似文献

A key development in journalism over the past decade has been the rise of web analytics for real-time measurement of how audiences respond to news content. While this has led to concerns that analytics may contribute to a dumbing down of news, our understanding of the impact analytics have on journalism culture is still limited. This study explores individual, organizational and platform-specific influences on ways in which journalists and newsrooms access, use, interpret and apply analytics in their daily work. It argues that, increasingly, analytics are beginning to shape and reshape journalistic roles, values, norms and practices across different types of newsrooms. These developments are contributing to processes of functional differentiation in the journalistic field, which is found particularly in emerging practices of day- and platform-parting. The study argues that this differentiation has important consequences for scholars wanting to study news production, distribution and content in the digital age. 相似文献

This study investigated a potential moderator of the association between popularity and relational aggression: social dominance orientation (SDO), the degree to which an individual endorses the importance of social hierarchy. One hundred eighty‐five ninth graders completed a sociometric assessment of RA and popularity, and a self‐report SDO measure. SDO was positively associated with popularity for both boys and girls, and with RA for girls. Popularity and RA were positively correlated for both genders. Regression analyses showed that SDO moderated the association between popularity and RA for girls, but not for boys. Girls who were both popular and who were social dominance‐oriented were particularly high in peer‐nominated RA. SDO may provide a useful framework for understanding the role of popularity in adolescent peer groups. 相似文献

In a study with 17,785 subjects obtained over the Internet from the United States and 47 other countries, Kinsey's hypothesis that sexual orientation lies on a continuum was supported. Self-identifications of subjects as gay, straight, bisexual, and other corresponded to broad, skewed distributions, suggesting that such terms are misleading for many people. Sexual orientation range—roughly, how much flexibility someone has in expressing sexual orientation—was also measured. The results support a fluid-continuum model of sexual orientation, according to which genetic and environmental factors determine both the size of the sexual orientation range and the point at which an individual's sexual orientation is centered on the continuum. 相似文献
