Accelerating new product diffusion: How lead users serve as opinion leaders in social networks

In social networks or, more specifically, online communities on tech-products, opinion leaders are important sources of advice for other consumers in the adoption and diffusion of new products. However, possibilities for potential users to exert their influence on opinion leadership are ignored. This study determines whether and how lead users may serve as opinion leaders in social networks and advise other consumers in the adoption and diffusion of new products. Our survey with 308 users in the Xiaomi and Huawei communities suggests that higher lead userness is positively and significantly associated with the likelihood of opinion giving and passing. Product-possessing innovativeness has a higher impact compared with information-possessing innovativeness. Product involvement does not enhance the effect of information-possessing innovativeness. The findings provide a better understanding of the formation of opinion leadership in social networks for an accelerated diffusion of new products.     

Making life: a brief history of human-robot interaction

This article is based on a talk for the Third Annual Eugene H. Fram Chair in Applied Critical Thinking lecture at Rochester Institute of Technology, which took place on 23 September 2014. The talk weaved together a brief history of robots, feral data, the internet of things, and consumer materiality to illuminate how life infuses our imagination of technology. This article illuminates the intersection of culture and technology and provides a lively history of the interactions between humans and robots.     

Reference points for measuring social performance: Case study of a social business venture

We present a longitudinal qualitative case study to elaborate on how a social venture forms reference points for social performance. Although organizations increasingly use various social performance targets to direct their operations, the scholarly knowledge on social performance reference points remains limited. We make use of the prior accounting literature and draw on the idea of compromising accounts to discuss how provisional and performative metrics can have a significant role in how organizations develop new ways to evaluate their social performance. Given that the social performance reference point criteria are ambiguous and the corresponding referents malleable, performative accounts are helpful as they can intervene in the organizational life by making particular things visible, providing space for interpretations, and facilitating discussion, thus creating temporary settlements and enabling opportunities for productive compromises between different organizational groups and evaluative principles. The recursive feedback loops between reference point referents, criteria and accounting artefacts help the organization to make sense of its own social performance and interpret the associated performance feedback, and thereby provide ground for organizational decisions on further action. Moreover, we discuss how imperfect accounts can be useful for social businesses in their pursuit of developing their activities and achieving social impact.

Corporate social responsibility and employee’s desire: a social influence perspective

Corporate social responsibility (CSR) is an increasingly important topic in management, especially in organizational behavior field across the globe; however, this concept is still in its infancy in Pakistan. In this study, we examined the effect of employees’ perceptions about CSR on their Desire to have a Significant Impact through Work (DSIW). We suggested the serial mediation of organizational identification and organizational pride in this relationship. The time-lag data of middle managers were collected from a well-known Pakistani firm that is actively engaged in CSR. The data consist of 187 observations and were analyzed using structural equation modeling in AMOS software. The results show that CSR positively affects employees’ identification that in turn make employees proud of their organizational membership and finally pride leads to employees’ DSIW. The study contributes in CSR and organizational behavior literature and provides managerial implication to enhance the positive psychological state of employees.     

Training as a social purpose: are economic and social benefits delivered?

This paper reports original research which measures the social and economic impact of training and skills development on individuals who participated in training provided by social purpose, nonprofit organizations. An implicit policy assumption is that such organizations contribute to social and economic regeneration. Examining the costs and benefits of training to trainees, an adapted Return on Investment methodology measures any economic benefit, while an Index of Social Benefit measures changes in individual well‐being. The results demonstrate that while changes to both the economic and social well‐being of trainees occur, it does not necessarily relate solely to the training they received. Instead, changes reflect other, often complex, aspects of trainees’ lives, although training may facilitate change. Furthermore, social purpose, nonprofit organizations need to evince the socioeconomic benefits of their training programmes to secure future funding, public or private, but proving their successful delivery may be difficult to determine.     

Extending network analysis with social inclusions: A Chinese entrepreneur building social capital

Social network analysis is a highly useful tool to study the way individuals form alliances to cope with their daily tasks on the micro-level. We can map the interaction between the key persons involved into a graph, representing the social network. The result is then a snapshot of who interacts with whom and why/how at the time the data were collected. However, when trying to apply it to a higher level, real life problems, this method of analysis seems to deviate from the way people form networks of relationships in social practice. In social practice, human actors tend to form relationships on the basis of institutional affiliation and inclusion in social groups. This paper intends to use Social Integration (SI) developed at Erasmus University Rotterdam on the basis of Karl Weick’s organization theory to enrich current social network theory with a module that links networks on the basis of multiple inclusions of actors in several social-cognitive groups (networks). The expanded model is tested on a Chinese business case.     

Emoji rhetoric: a social media influencer perspective

ABSTRACT

Social media require a marketing rhetoric that embraces emerging language use and shifting communication norms. Emojis have become quintessential elements of social media communication; yet, their role in supporting persuasion attempts has not been systematically analysed. Drawing on general rhetoric literature, this paper dissects, portrays and labels social media influencers’ persuasive attempts to initiate engagement through emojis. The focus on influencers is justified because of their dual roles as marketers and active social media users. 600 Weibo posts by the top 200 Weibo influencers were collected to develop a taxonomy of emoji-based verbal moves aimed at encouraging responses in followers. The resulting taxonomy demonstrates that emoji use by social media influencers is complex and strategic and serves multiple persuasive and communicative purposes.
