Illegal wildlife trade (IWT) is an omnipresent global threat to ecological, social, and economic systems. Marketing expertise can aid in the mitigation and reduction of crime against wildlife using a variety of mechanisms. This paper focuses on how social media usage relates to the framing of conservation appeals. By studying the content of existing blogs, articles, white papers, and other online...
The context for creating, sharing and accessing knowledge is rapidly changing at global and local levels as new technologies and approaches are introduced. These changes are driven and enabled by digital technologies, but who wins and who loses, and how do we ensure that development takes place in an equitable manner, and we move towards the kind of societies in Africa that citizens themselves would...
Higher education faces challenges on many fronts, including new learning models such as MOOCs, new forms of credentialing that question the value of a diploma, and a generation of students raised on socially-enabled technologies that view creating and sharing information differently. Clearly change must occur, but existing siloed models are well-ingrained into the culture. In this paper, we use complex...
With the development of mobile internet, wireless communications via mobile devices, which is typically in the form of Delay Tolerant Networks (DTNs), becomes a hot research topic. One critical issue in the development of DTNs is the routing. Although there are a lot research works addressing routing issues in DTNs, they handle routing problem from only one or two aspects, which cannot produce an...
Since mobile devices nowadays have become ubiquitous, several types of networks formed over such devices have been proposed. One such approach is opportunistic networking, which is based on a store-carry-and-forward paradigm, where nodes store data and carry it until they reach a suitable node for forwarding. The problem in such networks is how to decide which the next hop will be, since nodes do...
In this paper, three IT-based startups are presented that have each "hitched their wagon to a star" and have built their fledgling enterprise by blending the social, mobile, and instant elements of IT into their startup. This paper takes the form of a case study that first describes the founding story of one startup, Tweet Photo, with specific attention paid to the elements that prompted...
Service Innovations have played an important role in enabling social initiatives and in many cases have facilitated bridging the economic divide. In this paper we examine a few successful case studies in the context of developing economies, which have implemented sustainable service innovations. The motivation behind the paper is to understand how technology driven service innovations are bridging...
This is a report intended to describe a research about assessment of learning activities done in a virtual forum. Student's messages in the forum as a whole were considered as analysis unit. It was employed a content analysis technique to identify characteristics involved in the messages. Categories and indicators for analysis were defined from the Community of Inquire Model, adapted specifically...
With the growth in the past few years of social tagging services like Delicious and CiteULike, there is growing interest in modeling and mining these social systems for deriving implicit social collective intelligence. In this paper, we propose and explore two probabilistic generative models of the social annotation (or tagging) process with an emphasis on user participation. These models leverage...
