Effects of Physical Exercise on Memory – a Study

The motivation behind this audit is to furnish a depiction of the logical proof of the profits of physical action on health and well-being, centering especially on the aversion of no communicable illnesses (Ncds – likewise regularly alluded to as unending infections), and to present case investigations of 'what works' in distinctive settings and contexts

Monetary Rewards for Open Source Software Developers

Open source software (OSS) has changed the landscape and economics of software industry. Large software firms are changing their business models to incorporate OSS for long term success. As a result of greater organizational involvement in OSS, there is an increased prevalence of reward options for OSS developers. However, introducing compensation/rewards to these ideologically motivated communities may threaten their sustainability. We don’t know the nature and type of rewards that would be acceptable in OSS developer community. Using grounded theory methodology, we extracted the concepts regarding developers’ perception of rewards in OSS community and how developers prefer to be compensated. This paper contributes to the literature of open source software development by (1) providing in depth examination of the developers’ intention to work on the OSS project if compensated (2) providing an initial theory for understanding when compensation helps an OSS project and when it hinders

Impact of Financial Benefits on Open Source Software Sustainability

In recent years, the success of open source software (OSS) has attracted proprietary software firms, who now actively participate, and sponsor OSS development. Though researchers agree that for the progress of OSS projects, financial support, rewards, and incentives are critical if not essential, we are yet to understand the dynamics of compensation structures/policies and their impact on the long-term sustainability of OSS projects and communities. In this research, we aim to explore the role of developers’ perceived asymmetry in compensation in OSS projects. Using grounded theory procedures to code and analyse the textual responses from the developers, we find a mixed opinion on whether the perceived asymmetric distribution of project’s financial resources, helps or impedes the progress of an OSS project. We find that fair-terms, transparency and effective communication practices are essential to the sustainability of OSS projects, even with perceived asymmetric compensation

Audience Acquisition in Online Resource Mobilization: Quantifying the Relationship with Influential Actors

The literature recognizes the potential of social media as an alternative channel for promoting the causes of social movements, but little is known about the factors that act on the endeavors by social movement organizations to expand their base of sup-porters in social media environments. Drawing on theories of resource mobilization and social networks, we present a framework for studying how the presence of in-fluential actors or users with a high number of followers in online social networks, can influence the acquisition of new followers by a social movement organization. We collected Twitter data from a major organization in the global justice movement and found evidence that suggests a relationship exists between influential actors and the audience acquired by the social movement organization. However, our model suggests this relationship dwindles as the popularity or number of followers of in-fluential actors reaches extreme large values. Our study sheds light for addressing future questions concerning the factors that drive the propagation of ideologies in social media environments raised by actors of social movements and other social figures in their efforts for bringing about social change

How is the review helpfulness evaluated?

A user-generated review that is perceived as helpful is valuable for both customer and the retailer, and that is why online markets such as Amazon.com collect public opinion on reviews that are perceived more helpful. Review platforms allow customers to vote for reviews they deem helpful. While prior literature has examined what drives the helpfulness of reviews, many of these studies have looked at drivers of perceived helpfulness of reviews in isolation. Using the lens of dual process theory, this research examines how consumers evaluate the helpfulness of a review. We propose a framework and provide empirical evidence for the evaluation of the review helpfulness process. We find that extreme reviews have a higher effect on review helpfulness compared to moderate reviews, and this effect is mediated by the depth and sentiment of the review content

RESOURCE MOBILIZATION IN SOCIAL MEDIA: THE ROLE OF INFLUENTIAL ACTORS

This research in progress studies the role of social media as a resource for contemporary social movements in their endeavors to bring about social change. Current studies on this topic have largely regarded social media as an alternative channel for communicating situational information during protests against repressive regimes or perceptions of fraudulent democracy. Drawing on theories of resource mobilization and social networks, we present a framework for studying how the presence of influential and popular actors in social networks, can influence the acquisition process and the number of new followers by a social movement organization. We collected Twitter data for a major social movement organization in the global justice movement and found evidence suggesting that the existence of popular figures, impacts to some extent, the audience acquired by the social movement organization. We also conclude that the geographic location of these popular figures acts as a moderator for this effect. Our study lays the groundwork for answering questions regarding the sociotechnical dynamics that influence the propagation of ideologies in online environments promoted by groups and organizations concerned with societal issue

Challenges in Short Text Classification: The Case of Online Auction Disclosure

Text classification is an important research problem in many fields. We examine a special case of textual content namely, short text. Examples of short text appear in a number of contexts such as online reviews, chat messages, twitter feeds, etc. In this research, we examine short text for the purpose of classification in internet auctions. The “ask seller a question” forum of a large horizontal intermediary auction platform is used to conduct this research. We describe our approach to classification by examining various solution methods to the problem. The unsupervised K-Medoids clustering algorithm provides useful but limited insights into keywords extraction while the supervised Naïve Bayes algorithm successfully achieves on average, around 65% classification accuracy. We then present a score assigning approach to this issue which outperforms the other two methods. Finally, we discuss how our approach to short text classification can be used to analyse the effectiveness of internet auctions
