The value of enterprise social media applications, components, and users is difficult to quantify in formal economic terms such as Return On Investment. In this work we propose a different approach, based on human service to other humans. We describe a family of metrics, Return On Contribution (ROC), to assist in managing social software systems. ROC focuses on human collaboration, namely the c...

When aggregating preferences of agents via voting, two desirable goals are to incentivize agents to participate in the voting process and then identify outcomes that are Pareto efficient. We consider participation as formalized by Brandl, Brandt, and Hofbauer (2015) based on the stochastic dominance (SD) relation. We formulate a new rule called RMEC (Rank Maximal Equal Contribution) that is pol...

Motivating user participation is an important issue for the survival of social web and social software applications. In our previous work demonstrated that a point-based incentive encourages contribution to a social networking site. This paper presents a follow-up analysis after a full deployment of the incentive mechanism to the entire user community. We address an issue uncovered in our previ...

Relationship marketing provides a new foundation for thinking, genuine change in values and ethics and a new logic that sees consumers as the prime drivers of the value creation process. It seems to have a lot to offer to social marketing, however, despite its potential, the social marketing field is responding slowly to relational thinking. This research demonstrates that relationship marketin...

We examined the robustness of the results with four approaches. First, as Podsakoff et al. (2003) recommend, we employed Harman’s onefactor test. This test assesses the threat of common method bias by indicating whether a single latent factor offers a viable alternative explanation of the analysis. The one-factor latent model yielded a chi-square of 6063.27 (d.f. = 209). The fit of the one-fact...

The association between happiness and social relationships was examined in 9to 12-year-old children. Participants included 432 children and their parents. Children’s happiness was assessed using self-rating scales, parent’s ratings, and the Happiness and Satisfaction Subscale from the Piers-Harris Children’s Self-Concept Scale, Second Edition (Piers and Herzberg 2002). Children’s social relatio...

Europe is in a deep economic crisis and social economy and cooperatives are getting more interest by academics, firms and politicians because they can contribute to the economic, social and environmental development, in a sustainable and responsible way, being key for the implementation of new employment sources and the expansion of social responsibility as a development mean.

Knowledge sharing within an organization allows it to develop a competitive advantage over its rivals. However, sustaining and motivating members of knowledge sharing groups to contribute knowledge is a challenge for many organizations. To address this problem, organizations have implemented new knowledge sharing tools such as Wikis to facilitate knowledge contribution, although these have had ...
