Online Health Communities (OHCs) have emerged as a pivotal resource for individuals managing chronic diseases, serving as a vital supplement to traditional healthcare delivery systems. This study seeks to investigate the dynamics of OHC engagement among users with chronic diseases at various stages of their membership lifecycle. We hypothesize that the initial objectives users have when joining OHCs significantly shape their continued involvement. By embracing the theories of Uses and Gratifications (U&G) and Social Support (SST), we examine how users' goals for seeking information and emotional support, as well as the support they receive in these areas, influence their progression through different stages of engagement. Our empirical analysis uncovers that the goal of seeking information is most closely associated with the selection stage, while the goals of seeking emotional support and receiving emotional support are more closely linked to the commitment stage. Moreover, the degree of alignment between seeking emotional support and receiving emotional support has a significant impact on users' commitment stage activities, whereas the alignment between seeking information and receiving informational support does not significantly affect users' activities. The pattern of user interaction also plays a role in shaping their commitment stage activities and moderates the relationship between emotional support and commitment stage engagement. Our findings can guide OHC moderators and healthcare providers in more effectively leveraging OHCs for healthcare-related purposes.

The emergence of powerful information technologies (IT) has changed innovation and entrepreneurship in significant ways. Research in IT for entrepreneurship is relatively new and there is a growing interest from academics for further studies on investigating this area of research. This study reviews research carried out in the domain of IT for entrepreneurship. A total of 1005 papers, published between 1980 and 2021 were used to uncover the latent topics addressed in this domain. A topic modeling (LDA) algorithm was used to automate the process of extracting the initial research topics from the data. The results show that IT for entrepreneurship studies are classified into six aspects of research: entrepreneurship initiative and innovation, strategy, business process management and operation management, entrepreneurship education, industry analysis, and business model. The results raise awareness of IT-associated entrepreneurship areas of research, provide useful insights for future research, and informs practice in this domain of study.

Blogs are known for their information and knowledge sharing capabilities. Several theoretical frameworks have been proposed to study the factors that influence an individual's intention to use blogs for knowledge sharing. However, factors like content familiarity and design familiarity are lacking in the literature. Hence, this paper aims to extend past studies and investigate the influence of familiarity with blogs in knowledge sharing. Particularly, the purpose of this paper is twofold. The first objective is to explore the effect of familiarity in terms of content familiarity and design familiarity on individual intention to use a blog as a knowledge sharing tool. The second objective is to determine whether familiarity factors change with gender, blog experience, and cultural differences. The results show that content familiarity and design familiarity positively influence an individual's knowledge sharing behavior in blogs. In addition, content familiarity and design familiarity differ according to gender, blog experience, and cultural differences.
