The goal of this study is to examine the association between location-sharing in location based social networking (LBSN) services and social capital, such as trust, reciprocity, and network resources. A cross-sectional survey (n = 491) was conducted by adopting a simple random sampling method in 2014. The findings showed that intensity of LBSN services is positively associated with all social capital aspects. In general, compared to a group of non-users of LBSN services, those groups of users with low and high intensity of LBSN services were higher in trust, reciprocity, and network resources. Therefore, this study proposes theoretical and practical implications of location-sharing to scholars in social sciences demonstrating how use of LBSN services influences accumulation of social capital.  相似文献

Comparative social policy analysis has been shaped by the measurement of policy as a macro phenomenon. However, social policy theories have consistently asserted that policy entitlements vary across class, gender, ethnicity and the life-course. This paper synthesises a number of innovations to produce an approach which allows researchers to explore the policy heterogeneity within populations, across populations and over time. Using the example of maternity and parental leave, policy entitlements are identified through the calculation of financial support an individual would receive if they were to have a child, using a combination of legislative rules with representative survey sample. The results reveal far greater heterogeneity in policy entitlements than existing indicators suggest, with considerable implications for research on maternity and parental leave. This approach is not limited to maternity and parental leave benefits and demonstrates a way to explore comparative social policy in greater depth and detail.  相似文献

In 2007, Petrova and Tarrow coined the term transactional activism, arguing that, despite weak individual-level political participation, civil societies in Central and Eastern Europe were surprisingly strong due to their capacity to establish transactional links. Yet the research which followed, relying mostly on quantitative data, has not uncovered much evidence of how transactional activism works. To make advances here, we take a more qualitative approach and focus on transactional ties among NGOs, developing a more fine-grained conceptualization. Specifically, we distinguish associative ties of loosely defined cooperation and interlocking ties based on the division of labour. We utilize this new conceptualization through a successful anti-corruption initiative known as ‘Reconstruction of the State’. The initiative presented itself largely in transactional terms (plurality of participating actors) and was extremely successful in the run-up to the Parliamentary elections in 2013 in the Czech Republic, inspiring similar initiatives abroad. We use social network analysis and qualitative interviews to test our concept of interlocking transactional ties. In contrast to our expectations, we find limited division of labour in the initiative, with just one organization, in the main, shouldering most of the important tasks. We use our findings to question the previously claimed importance of transactional activism in Central and Eastern Europe. Specifically, we call for more robust evidence describing how cooperation among organizations empowers civil society.  相似文献

Prior studies (see e.g. [Rosch, E. (1975). Cognitive reference points. Cognitive Psychology, 7, 532–547]) indicate that multiples of ten serve as cognitive reference points with a view to perceiving and evaluating numbers. In order to explore whether managers set dividends per share (henceforth DPS) at or just above a cognitive reference point, we perform a digital analysis on US firms’ DPS for the period 1995–2004. That is, based on the theory of cognitive reference points, DPS of $2.00 will be viewed as being abnormally larger than DPS of $1.99, whereas the actual difference only amounts to a marginal $0.01. Results presented in this paper indicate that managers fall back on cognitive reference points when they set DPS, which shows in significantly more (fewer) zeroes (large digits) in the second-from-the-left position of DPS than would normally be expected. Overall, results presented in this paper tally with prior findings on odd-ending prices and price clustering documented in related disciplines.  相似文献

This paper employs a field experiment to assess whether interpersonal contact changes domiciled individuals’ attitudes of the homeless. Volunteers for Project Homeless Connect—a one-day event that provides social services to the homeless—were asked to complete a pre- and post-survey. The results provide mixed support for the contact hypothesis. After volunteering, respondents were far less likely to see homelessness as the result of individual characteristics, such as substance abuse or work aversion. However, opinion was remarkably stable when it came to policy preferences. The results cast doubt on the conventional wisdom that individuals’ perceptions of the causes of homelessness track closely with their preferences for governmental policy.  相似文献

ABSTRACT

Economic globalization is an important aspect of the ideology of the United States. The US has long been championing notions of a global free-market system, free of trade barriers. One of the ways in which the US has tried to challenge these trade barriers is through economic sanctions under Section 301 of the Trade Act of 1974. Section 301 gives broad powers to the President to combat unfair foreign trade practices. However, these broad powers have also been used for protectionist measures themselves. This paper examines the power of Section 301 and whether it undermines economic globalization, using the Reagan tariffs on semiconductors as a case study. This paper argues that Section 301, instead of promoting economic globalization, undermines it by its own protectionist nature.  相似文献

Cluster point processes comprise a class of models that have been used for a wide range of applications. While several models have been studied for the probability density function of the offspring displacements and the parent point process, there are few examples of non-Poisson distributed cluster sizes. In this paper, we introduce a generalization of the Thomas process, which allows for the cluster sizes to have a variance that is greater or less than the expected value. We refer to this as the cluster sizes being over- and under-dispersed, respectively. To fit the model, we introduce minimum contrast methods and a Bayesian MCMC algorithm. These are evaluated in a simulation study. It is found that using the Bayesian MCMC method, we are in most cases able to detect over- and under-dispersion in the cluster sizes. We use the MCMC method to fit the model to nerve fiber data, and contrast the results to those of a fitted Thomas process.
