Exploring the link between government funding and efficiency in nonprofit colleges

Previous literature has suggested that federal funding can hinder the efficiency of nonprofit organizations, but this has yet not been empirically tested. This study used a two‐stage data envelopment analysis (DEA) model to measure the efficiency of a set of private nonprofit teaching‐oriented colleges, then estimate the impact of federal and state funding on organizational efficiency. The findings indicate that, on average, increases in neither state nor federal funding effect efficiency of nonprofit colleges. Increasing state funding negatively impacted the efficiency of public colleges (N = 799). This study suggests that the challenges for nonprofits that accompany government funding may not rise to a quantifiable negative effect on efficiency.     

基于最大收益的无线虚拟网络重映射算法

针对无线环境的动态性及虚拟网络请求到达与离开的随机性,使得物理网络负载分布不均衡,导致后续请求的接受率降低的问题,提出一种无线网络虚拟化中的两阶段重映射算法（two stages reconfiguration scheme for wireless network virtualization,TR-WNV）。该算法通过第1个阶段选出合适的虚拟网络进行重映射,接着在第2个阶段按照优先级对已选出的虚拟网络进行重映射,并根据离散度来判断每次映射效果。最后,通过仿真对算法进行验证,结果表明该算法在保证虚拟网络请求收益最大化同时,有效提高了虚拟网络请求接受率,实现整个底层网络的负载分布均衡。     

When is brokerage negatively associated with economic benefits? Ethnic diversity,competition, and common-pool resources

There is a growing body of literature positively linking dimensions of social capital to economic benefits. Yet recent research also points to a potential “dark side” of social capital, where over-embeddedness in networks and the pressures associated with brokerage are hypothesized to constrain actors, having a negative effect on economic outcomes. This dichotomy suggests that context is important, yet the overwhelming majority of existing empirical evidence stems from socially homogenous populations in corporate and organizational settings, limiting a broader understanding of when and how context matters. We advance this discourse to a socially fragmented, ethnically diverse common-pool resource system where information is highly valuable and competition is fierce. Merging several unique datasets from Hawaii's pelagic tuna fishery, we find that network prominence, i.e., being well connected locally, has a significant, positive effect on economic productivity. In contrast, we find that brokerage, defined here as ties that bridge either structurally distinct or ethnically distinct groups, has a significant, negative effect. Taken together, our results provide empirical support to widespread claims of the value of information access in common-pool resource systems, yet suggest that in ethnically diverse, competitive environments, brokers may be penalized for sharing information across social divides. Our results thus contribute to an emerging theory on the fragile nature of brokerage that recognizes its potential perils and the importance of context.     

China and global internet governance: toward an alternative analytical framework

Drawing on historical methods, this study assesses the conventional “cyber-sovereignty” framework, which has been used to capture and interpret China’s stance toward global Internet governance. This framework focuses on political control and tends to reduce China’s policies to the attempts by an authoritarian state to elevate governments and intergovernmental organizations to be the only legitimate governors of global cyberspace. As it traces the evolution of China’s relationship with the global Internet in the past three decades, the study demonstrates that China’s stance is more complex than the prevalent framework allows and that it is both built upon and different from the US-centric, market-oriented Internet governance scheme. This study recognizes the inadequacy of the conventional framework and invokes a theory of critical political economy of communication, thereby offering an alternative model to explicate the complex power dynamics behind China’s changing strategies. The alternative model advanced in this study is based on the understanding of China’s evolving approach as the product of multifaceted interactions among a group of power-holders that include both state agencies and business units on the transnational level.
