Building protest online: engagement with the digitally networked #not1more protest campaign on Twitter

This article examines engagement with digitally networked, politically contentious actions. Maintaining engagement over time is a key challenge for social movements attempting to network digitally. This article argues that proximity serves as a condition to address this challenge, because it configures the personal networks upon which transmission depends. This is a paradox of digital activism: it has the capacity to transcend barriers; however, proximity is essential for sustaining relations over time. Examining Twitter data from the #not1more protest campaign against immigrant deportations in the United States, quantitative and social network analyses show a differentiated development of engagement, which results in a particular geographical configuration with the following attributes. First, there is a robust and connected backbone of core organizers and activists located in particular major cities. Second, local groups engage with the campaign with direct actions in other cities. Third, a large and transitory contingent of geographically dispersed users direct attention to the campaign. We conclude by elaborating how this geographically differentiated configuration helps to sustain engagement with digitally networked action.     

Incorporating social networks into leadership development: A conceptual model and evaluation of research and practice

Multilevel and relational views of leadership are expanding the focus of leadership development beyond individuals' knowledge, skills, and abilities to include the networked patterns of social relationships linking members of dyads and larger collectives. In this review, we present a conceptual model explaining how three distinct approaches for network-enhancing leadership development can improve the leadership capacity of individuals and collectives. We then present a review of the leadership development literature and the results of a survey of 282 practitioners to assess the extent to which these approaches have been examined in research and implemented in practice. Our review revealed that leadership research and leadership development practice are outpacing leadership development research in terms of incorporating networks. We aim to spur future research by clarifying the targets, objectives, and underlying mechanisms of each network enhancing leadership development approach in our conceptual model. Further, we identify additional literature, not traditionally considered within the realm of leadership development that may help advance empirical examinations of these approaches.     

PLANNING FOR TRUCK FLEET SIZE IN THE PRESENCE OF A COMMON-CARRIER OPTION

This paper considers a class of network optimization problems in which certain directed arcs must be covered by a set of cycles. Our study was motivated by a distribution planning problem of a commercial firm that had to make deliveries over several origin-destination pairs (directed arcs) and that could service any demand arc by using a vehicle in its own fleet or by paying a common carrier. The problem is to determine an optimal fleet size and the resulting vehicle routes while satisfying maximum route-time restrictions. We formulate the problem, describe some approximate solution strategies, and discuss important implementation issues.     

Community e-gateways: locating networks and learning for social inclusion

The provision of community e-gateways (community-based facilities providing public access to computers and the Internet) has been seen as a way to address the 'digital divide', particularly for people from deprived neighbourhoods. In the UK, policy and practitioner literature has stressed that for these centres to be successful they need to have strong social connections and be able to provide opportunities for interactive learning and content creation. Through a detailed analysis of one community e-gateway, which formed part of a wider study of public access provision, this article analyses the strengths and weaknesses of this advice drawing on broader sociological literature relating to social networks, network mapping and communities of practice. It concludes that greater attention needs to be paid to the significance of weak ties, two-way boundary spanning and the resource requirements of social networks for the policy objectives to be fully achieved.     

Communities, alliances, networks and knowledge in multinational firms: A micro-analytic framework

We develop a model of the micro-process of knowledge acquisition, dissemination, and application in the networks of alliances that have become important sources of external knowledge for multinational firms. Based on the concept of communities of practice as sources of highly tacit know-how, this model addresses the use of alliances with local partners to acquire tacit knowledge on a sub-unit level and to then share this knowledge throughout the firm via an internal network of community-level alliances. We suggest that the supposed advantage of multinational firms in accessing and reconstituting knowledge from widely spread sources is composed of multiple micro-processes at sub-unit levels, and therefore much more complex than usually presented.     

网络融合下的产业交叉进入及企业横向兼并行为研究

本文基于二阶段动态古诺竞争模型,考虑了通信产业网络运营商横向兼并前后边际成本的变化,研究存在n家运营商的同质产品市场中,企业进行横向兼并的条件,并对横向兼并所引起的运营商利润变化及社会福利的变化进行了探讨。结果表明,随着横向兼并后边际成本节约程度的增加,运营商利润和社会福利都会增大。本文尝试对在网络融合下,媒体交叉竞争、产品同质化的过程中,网络运营商之间横向兼并行为进行规范的经济学分析,有关结论可以为政府制定网络融合下通信产业重组的相关政策提供一定的理论依据。

My network,my self: A social network approach to work-based identity

As the organizational landscape becomes increasingly turbulent and the gig economy grows, the conventional anchors for a work-based sense of identity – a relatively stable organization, workgroup, and occupation – are losing relevance. We argue that a “network identity,” defined as the core, distinctive, and more or less enduring character of a set of social ties (e.g., “we are high-achievers”), helps fill this growing void because individuals’ networks often reflect agency and have more or less fluid boundaries and portability. These attributes enable individuals to develop or join networks that may transcend specific contexts and adapt to change. An individual’s network identity simultaneously implicates all three levels of self – individual, relational, and collective – such that it is a potentially very powerful means for realizing his or her identity motives. Crossing the dimensions of network boundary strength and network density, we offer a 2 × 2 typology of networks and discuss their implications for members’ network identities and what kinds of individuals might prefer each network.     

Impartiality,friendship-networks and voting behavior: Evidence from voting patterns in the Eurovision Song Contest

What is the extent to which a country's political institutions impact aggregate voting behavior in a comparative perspective? More specifically, are citizens in some countries more inclined vote on the basis of ‘quality’ or ‘merit’ over ‘friendship’ or ‘loyalty’, and if so, why? This paper seeks to address how the extent to which a country's political institutions are impartial (treats all citizens equally, free from corruption, strong rule of law) impact aggregate citizen behavior. When political institutions are more (less) impartial, success in society is more often on the basis of merit (patrimonial ties). This test cases is voting in the Eurovision Song Contest (ESC) from 1975 to 2012 among pairs and blocs of ‘voting friends’. The theory elucidates that given that certain pairs or blocs exhibit systematic voting bias for one another over time, the bias will be considerably less among impartial states than those with highly partial institutions. Using several measures of ‘friendship’, I find strong empirical evidence for this claim, even when controlling for myriad alternative factors and taking into account various voting regimes. The analysis gives us new insights on how political institutions condition aggregate citizen behavior in general and that although there is much bias in ESC voting, not all bias is equal among friend-countries.
