ABSTRACT

While collaboration among individuals, work groups, and organizations is central for understanding the performance of public agencies, most studies have focused on collaboration between organizations or sectors. We develop a model that focuses on two types of collaborative behavior: between persons (both horizontal and vertical) and between work units. We empirically test our hypotheses using data on work collaboration and perceptions of public agency performance from the United States federal government. We introduce a method for estimating the impact of different types of collaborative behavior that also accounts for nonlinear effects and a dependent variable that takes ordered values. We find that intra-organizational collaborative behavior has a large impact on organizational performance and that horizontal collaborative behavior between workers has the greatest impact among the specific types.  相似文献

The article examines the role of lending rates, imports and growth on the duration of self-employment in Zimbabwe while the country embarked on trade liberalisation. The variables were selected because of their importance as policy variables in reform programmes and also their importance to small entrepreneurs. Previous research has established the importance of an initial endowment and other measures of human capital on entry into self-employment as well as growth of the respective enterprises. We show that such initial conditions do not always give robust results. Instead, duration of self-employment is negatively related to higher lending rates, increased imports and structural change, but responds positively to growth.  相似文献

Using data from the Philippines, we study the impact of mobile phones on the prices agricultural producers receive for their cash crop. We first look at the impact on price of mobile phone ownership at the household level. Because this masks a considerable amount of heterogeneity, we then look at the impact on price of the intrahousehold allocation of mobile phones. We find that whether the household owns a mobile phone has no impact on price, but whether a farmer or spouse owns a mobile phone is associated with a 5- to 8-per cent increase in price.  相似文献

Free market ideology has continued its hegemonic reign notwithstanding considerable opposition. Under capitalism, the relationship between the political and economic realms is intricate. This inquiry on corporate restructuring in Singapore between the late 1990s and the early 2000s scrutinizes how a dominant state collaborated with the multinational corporations to reconstitute their accumulation regimes to outlast the business cycles. Based on six cases, the findings underscore the critical role of the state on the subject of restructuring. The peculiar configuration of the relations between the state and labour in Singapore shaped how they negotiated the restructuring process with the companies. While those involved reckoned that training, research and technology were pivotal, the foregoing were not the panacea that optimistic consultants had made them out to be. The interactions among capital, labour and the state remained the underpinnings of solutions.  相似文献

A decade after retrocession to China, Hong Kong still has limited democracy. Only half of the legislature is directly elected by the people, and the Chief Executive – the leader of Hong Kong government – is chosen by an election committee of 800 people, most of them loyal to Beijing. In December 2007, the Chinese Central Government announced that the direct election of the Chief Executive and the whole legislature may be implemented from 2017 and 2020, respectively. Still, in this paper it is suggested that real democracy in the foreseeable future is unlikely. This paper demonstrates the existence of a “power elite” of tightly knit business-state networks in Hong Kong society and argues that this constitutes a systemic barrier against further democratic development. Central to the discussion is an analysis of the formation and composition of the legislature and the relations to the elite-interlocks among influential organisations in society. Mainly based on 2006‐07 data, the Elite Database which is subject to network analyses is composed of 1531 individuals holding 1854 seats from 40 listed corporations, 27 government committees, 20 non-governmental organisations, and eight universities.  相似文献

The effects of political news on the mass audience are usually difficult to establish empirically. Recent models of mass communication effects have held that political knowledge is a better indicator of media reception than traditional measures of exposure. This claim is tested in two studies of attitudes toward Democratic and Republican leaders during the 1996 U.S. presidential primary campaigns. The impact of messages from three types of political talk radio (PTR) is examined: Rush Limbaugh, other conservative hosts, and liberal/moderate hosts. Political knowledge and exposure to talk radio are found to be equally good predictors of attitudes toward political leaders when studied separately. However, when tested against one another, exposure is the more effective measure. Agreement between Rush Limbaugh's messages and his audience's attitudes toward political figures is consistent and strong. Biased processing of PTR content by audience members with partisan predispositions contrary to those of the host is also examined.  相似文献

The emerging field of risk communication has yet to thoroughly grapple with how the mass media report risk. Through a content analysis of five newspapers noted for their science reporting, newspaper coverage of four environmental hazards is compared to media coverage of more traditional risky events. In general, these slow‐to‐develop stories are reported in much the same way as more traditional disaster stories. News accounts emphasized an event orientation, framed risks in terms of human activity rather than social and political contexts, described risk in terms of harms and benefits, and relied on traditional sources. The authors then explore how this version of mass‐mediated risk might change current definitions of risk communication and how a mediated construction of risk may influence public perception of the political choices these issues raise.  相似文献

An increasing number of studies in political communication focus on the “sentiment” or “tone” of news content, political speeches, or advertisements. This growing interest in measuring sentiment coincides with a dramatic increase in the volume of digitized information. Computer automation has a great deal of potential in this new media environment. The objective here is to outline and validate a new automated measurement instrument for sentiment analysis in political texts. Our instrument uses a dictionary-based approach consisting of a simple word count of the frequency of keywords in a text from a predefined dictionary. The design of the freely available Lexicoder Sentiment Dictionary (LSD) is discussed in detail here. The dictionary is tested against a body of human-coded news content, and the resulting codes are also compared to results from nine existing content-analytic dictionaries. Analyses suggest that the LSD produces results that are more systematically related to human coding than are results based on the other available dictionaries. The LSD is thus a useful starting point for a revived discussion about dictionary construction and validation in sentiment analysis for political communication.  相似文献
