Bracketing or reinforcing? Socio-economic status,network power,and online deliberation

The extent to which the deliberative scenario brackets socio-economic inequalities (i.e., functioning as an ideal public sphere) has been long-debating. This study empirically addresses this question in the online setting. We test whether offline advantages (i.e., economic and cultural capitals) can be translated into power in online deliberation and how their dynamic relations further influence interlocutors’ deliberation experience (i.e., perceived procedural fairness and validity claim). Power is conceptualized as network power, including prestige (indegree), leadership (outdegree), and brokering power (betweenness). A national sample of Singaporeans participated in a three-week online deliberation, and network power is measured based on the web log. The participants answered a two-wave (i.e., pre- and post-deliberation) survey to indicate individual attributes. Structural equation modeling finds that online deliberation brackets as well as reinforces offline status. Economic capital is suppressed while cultural capital translates into network power, which further influences interlocutors’ evaluation of the deliberation.     

How does time spent on WeChat bolster subjective well-being through social integration and social capital?

Although WeChat has recently spawned significant resolutions in technology-mediated social contact and interpersonal communication, the research regarding the social and psychological impacts of the newly emerging technology is relatively few. The primary purpose of the current empirical research is to unearth whether and how WeChat interaction could enhance overseas students’ sense of subjective well-being by concentrating on social integration, bridging relationships, and bonding relationships. Using web-based data of 228 Chinese subjects, the obtained results reveal that the time spent on WeChat significantly and directly impacts users’ subjective well-being. Additionally, the findings demonstrate that social integration, bridging relationships, bonding relationships are all significant predictors to subjective well-being. Furthermore, the perceptions of social integration and social capital could play the crucial mediating roles in the connection between WeChat use and the dependent variable of subjective well-being. Therefore, these outcomes may shed light on a more nuanced comprehending of the influence of the new social media interaction on sojourner’s social adaption and overall life quality in the digital age.     

Transnational experience and high-performing entrepreneurs in emerging economies: Evidence from Vietnam

Do high-performing entrepreneurs in the technology sector in emerging economies have more, or different, transnational experience than the founders of high-performing non-technology businesses? Employing Vietnam as a case study, we find that they do; the founders of high-performing technology-oriented businesses are 15 times more likely to have transnational experience in the U.S. compared to their non-technology peers, and are 35 times more likely to be graduates of American universities compared to founders of high-performing, non-technology-oriented business. The founders of high-performing non-technology businesses are more ‘place-based’, as they have predominantly lived and studied in Vietnam. Our data and methods are comprised of a logistic regression analysis of the biographical details of Vietnam's 143 highest-performing entrepreneurs; the founders of the 76 Vietnam's (non-technology-based) companies with the highest market capitalizations and the 67 founders of Vietnam's highest performing technology-oriented companies, in terms of private equity fundraising, as of April 2020. The paper's theoretical contribution is the advance it makes in analytical explanations of why technology-based entrepreneurs have more transnational experience, especially in the U.S., than high-performing founders of businesses in other sectors; this helps extend theory on the relationship between social and human capital and entrepreneurial performance, specifically in the technology sector.     

Migration and occupational careers: The static and dynamic urban wage premium by education and city size

Using matched employer-employee full population data on regional migrants in Sweden, this paper addresses the question whether the urban wage premium, and ‘thick’ labour market matching effects, are to be found across all educational groups, and whether the population threshold for these types of effects varies by educational category. Estimating initial wages, average wage level and wage growth 2001-2009, we find similar wage premiums for all workers in the three largest metropolitan areas, but that there are distinct population thresholds for these type of effects, regardless of educational background. However, job search behaviour as explaining dynamic effects over time seems to pertain mostly to those with higher education.     

基础设施PPP项目脆弱性影响因素研究

以基础设施 PPP 项目为对象,借助网络模型,对其进行脆弱性影响因素的研究。基础设施 PPP 项目作为一个系统,其脆弱性往往由脆弱性影响因素诱发。将影响因素作为网络中的节点,因素间的关联关系及强度作为边和权重,在此基础上构建无向加权网络。通过对网络模型参数的计算,可以按照重要程度对脆弱性影响因素进行排序,从而为基础设施 PPP 项目的风险管理提供理论依据和实践指导。

Water and Sewerage Charges in Scotland

The paper outlines the statutory arrangements governing water and sewerage charges in Scotland, and comments on the factors affecting the levels of charges. Trends in revenue expenditure over the period 1989–90 to 1992–93 are considered in relation to increases in personal community water charge levels, metered water rates, and costs per household. Non-domestic sewerage rates and industrial effluent charges are also discussed. Some comparisons are made with England and Wales and with other countries. The funding arrangements for capital expenditure and their effect on the levels of charges are described, with particular reference to debt levels and rising expenditure to meet UK and EC standards. Factors affecting future charge levels are also identified.
