Research on Social Engagement with a Rabbitic User Interface

Companions as interfaces to smart rooms need not only to be easy to interact with, but also to maintain long-term relationships with their users. The FP7-funded project SERA (Social Engagement with Robots and Agents) contributes to knowledge about and modeling of such relationships. One focal activity is an iterative field study to collect real-life long-term interaction data with a robotic interface. The first stage of this study has been completed. This paper reports on the set-up and the first insights

Does marketing and sales integration always pay off? evidence from a social capital perspective

Building on social capital theory, the authors view the marketing and sales interface as a set of inter-group ties and investigate how firms (1) generate value from inter-group relationships and (2) develop the social capital embedded in these relationships. Their findings suggest that social capital enhances, but can also limit, a firm’s performance depending on the characteristics of its customers. Their results also demonstrate that managing the marketing and sales interface at different levels of customer concentration is critical to the success of a firm’s performance.Marketing organization; sales organization; interface; social capital theory.

The determinants of the quality of Sales-Marketing Interface in a Multinational Customer Brand Focused Company: The Latin American Branches

Customer evolution and changes in consumers, determine the fact that the quality of the interface between marketing and sales may represent a true competitive advantage for the firm. Building on multidimensional theoretical and empirical models developed in Europe and on social network analysis, the organizational interface between the marketing and sales departments of a multinational high-growth company with operations in Argentina, Uruguay and Paraguay is studied. Both, attitudinal and social network measures of information exchange are used to make operational the nature and quality of the interface and its impact on performance. Results show the existence of a positive relationship of formalization, joint planning, teamwork, trust and information transfer on interface quality, as well as a positive relationship between interface quality and business performance. We conclude that efficient design and organizational management of the exchange network are essential for the successful performance of consumer goods companies that seek to develop distinctive capabilities to adapt to markets that experience vertiginous change

Faster Random Walks By Rewiring Online Social Networks On-The-Fly

Many online social networks feature restrictive web interfaces which only allow the query of a user's local neighborhood through the interface. To enable analytics over such an online social network through its restrictive web interface, many recent efforts reuse the existing Markov Chain Monte Carlo methods such as random walks to sample the social network and support analytics based on the samples. The problem with such an approach, however, is the large amount of queries often required (i.e., a long "mixing time") for a random walk to reach a desired (stationary) sampling distribution. In this paper, we consider a novel problem of enabling a faster random walk over online social networks by "rewiring" the social network on-the-fly. Specifically, we develop Modified TOpology (MTO)-Sampler which, by using only information exposed by the restrictive web interface, constructs a "virtual" overlay topology of the social network while performing a random walk, and ensures that the random walk follows the modified overlay topology rather than the original one. We show that MTO-Sampler not only provably enhances the efficiency of sampling, but also achieves significant savings on query cost over real-world online social networks such as Google Plus, Epinion etc.Comment: 15 pages, 14 figure, technical report for ICDE2013 paper.

Attention and Visibility in an Information Rich World

As the rate of content production grows, we must make a staggering number of daily decisions about what information is worth acting on. For any flourishing online social media system, users can barely keep up with the new content shared by friends. How does the user-interface design help or hinder users' ability to find interesting content? We analyze the choices people make about which information to propagate on the social media sites Twitter and Digg. We observe regularities in behavior which can be attributed directly to cognitive limitations of humans, resulting from the different visibility policies of each site. We quantify how people divide their limited attention among competing sources of information, and we show how the user-interface design can mediate information spread.Comment: Appearing in 2nd International Workshop on Social Multimedia Research 2013, in conjunction with IEEE International Conference on Multimedia & Expo (ICME 2013
