A dynamic perspective: local interactions driving the spread of social networks

ABSTRACT

This study takes a micro standpoint to quantitatively verify the extent to which local interactions affect the expansion of dynamic social networks. By reviewing and synthesizing the theoretical literature in this article, we seek to establish a pragmatic analytical framework to capture the underlying functioning of local interactions. It then aims to produce findings on seven distinct marketing campaigns in which the real-world virtual communities offer intact time-series connections. In our considered cases, the firm-to-consumer interactivity plays a pivotal role in social media marketing while the customer-driven influence advances individual information transmission. The significant positive relationships demonstrate features of interactivity within subgroups including reciprocal edges and directed 3-cliques associated with the evolution of the virtual community by electronic word-of-mouth (WOM) of both firm-to-consumer and consumer-to-consumer interactions. More importantly, the attenuation of local interactions to a large extent leads to the cut-off point of the growth of the dynamic social network.

The people behind the scenes: Episodic volunteering at fundraising events

Nonprofit organizations (NPOs) have become increasingly dependent on episodic volunteers (EVs), those that would help carry out an event with little training and expectation to commit to future events. Despite its importance to the survival of NPOs, the use of EVs with respect to fundraising has received little research focus. Furthermore, none of the existing studies identified examined how fundraising EVs differ from other EVs. This study seeks to contribute to our understanding of fundraising EVs using a global perspective. Data were generated using surveys distributed in seven countries, tallying more than 4,000 respondents. Variables included demographic characteristics, previous donation and volunteer history, motives, mode of volunteering, and overall experience. The data were analyzed by applying between-group (logistic regression on participation) and within-group analysis (ordered logistic regression on willingness to participate in the future). Data were further analyzed by examining differences by country. We found that country, gender, religion, income, employment, history of donations, mode of volunteering, and several motives, both intrinsic and extrinsic, were significant in the logistic regression analysis of participation in fundraising episodic volunteering. The ordered logistic analysis unexpectedly found that the only predictors to foster a willingness to engage again were the responsiveness of the event team and a desire to fulfill spiritual satisfaction. In recruiting and selecting EVs for fundraising events, NPOs should consider previous or current donors and those with regular volunteering experience and they should market volunteer opportunities towards those in search of spiritual fulfillment and meaning. Moreover, NPOs should prioritize quick and clear communication with fundraising EVs in order to foster a willingness to volunteer again. Lastly, NPOs should regularly assess for country-specific factors and contexts that may affect episodic volunteering in fundraising events. Our paper illustrates who fundraising EVs are, their motives, how they choose to volunteer, and what contributes to their willingness to volunteer again. Given the limited research on fundraising EVs, this study serves to help lay the foundation of research for this unique subgroup. Our aim was to not only address the dearth of literature but serve as a springboard for future research on fundraising EVs.     

地形因子对北京市土地覆盖变化的影响研究

目前国内外学者从人文因素方面对土地覆盖变化已进行了大量的研究,但是探讨地形因子(高程、坡度、坡向)对土地覆盖变化影响的研究还相对较少。鉴于此,文中以北京市土地覆盖动态变化为研究对象,通过定量、定位的研究方法分析不同坡度、不同高程带和不同坡向的土地利用类型在各个历史阶段内的土地利用变化情况。研究结果表明:建设用地、水体、耕地和水田主要分布在350m以下,且坡度小于6°的平地和缓平地上;林地主要分布在350~1200 m的中高地区域且坡度多在大于15°的斜坡和缓陡坡上,除平坡以外在其余各坡向分布均匀;草地主要分布在50~750m的高程区域且坡度在2°~25°的缓平地和斜坡上。研究结论表明:地形因子在很大程度上影响着北京市土地覆盖变化格局。     

领导力在项目组合管理中的影响研究

项目组合是连接战略和项目的桥梁。区别于以往有关项目管理中领导力的研究,针对高管和项目经理两种层次的领导角色,界定了领导力的内涵,从战略视角出发构建了领导力对项目组合绩效的影响作用模型,并运用偏最小二乘法和实证方法对理论模型进行检验。研究结果表明,高管及项目经理的领导力均对项目绩效、组合绩效有积极的影响,但项目绩效对组合绩效的作用并不显著。结论强化了领导力在项目组合管理中的关键作用,为研究组合绩效的提升机制提供了新的思路和方法。

持有金融机构股份与企业资金配置效率

采用2007年到2011年我国上市公司数据,就持有金融机构股份对投资现金流敏感度以及投资效率的影响进行分析,研究结果显示:持有金融机构股份会提高企业的投资现金流敏感度,会降低企业的投资效率,导致企业过度投资行为更加严重,而这种现象在民营企业中更加显著。
