Analysis of protein binding characteristics among Arabidopsis BBX protein family

Abstract Plants have evolved various mechanisms of adjusting their diurnal and seasonal growth and development in response to variations in day length and light quality. This plasticity is facilitated by intricate regulatory networksthat comprise transcription factors, whose expression is modulated by the activity of photoreceptors. In Arabidopsis, B-box (BBX) transcription factors, which contain one or two Zn-ligating B-box motifs in their N-termini, serve as key mediators of light signaling for photomorphogenesis, shade avoidance, and photoperiodic flowering. While multiple BBX proteins may function as a single regulatory unit, the binding networks that form among members of the BBX family have not been extensively investigated. Here, we have demonstrated that the homodimerization of two B-box motifs containing CONSTANS protein (BBX1), which regulates light signaling and is the most extensively characterized among all BBX proteins, requires at least three B-box motifs. Therefore, the number of B-box motifs may significantly influence heterodimerization among BBX family members. An interactome analysis of all 32 known B-box family members revealed that the binding affinity between group III and V proteins with only one B-box motif is relatively weaker than that observed among other group members. In fact, the group V proteins BBX26 and BBX27 rarely interact with other BBX members. Taken together, the results of this study emphasize the importance of the B-box motif in network formation among BBX proteins and provide insights into investigating the various signaling pathways mediated by these networks

E-commerce adoption within SME's in Ghana, a tool for growth?

Electronic commerce presents small and medium enterprises (SMEs) in developing economies the opportunity to compete on a global stage. With theoretical underpinning of the technology acceptance model (TAM) and technology-organisation-environment (TOE), this study investigated e-commerce adoption among SMEs in Ghana. Managers and owners of SMEs participated in both survey (n = 152) and interview (n = 38). Partial least squares regression analysis indicates that the introduction of point of sale (POS) machines for SMEs will improve offline cashless trading, which must necessarily precede online trading for an effective payment system to exist. An increased internet penetration rate would enable nationwide e-commerce participation rather than the current skewed practice with e-commerce dominance within southern Ghana. For the private investor, there exists a market for logistics services. The Ghana postal service must, however, take the lead to serve as a blueprint as well as a source of data for private investors

Why do people post and read personal messages in public? The motivationof using personal blogs and its effects on users’ loneliness, belonging, and well-being

The purpose of the current paper is to develop a theoretical model that identifies why people blog personal content and explains the effects of blogging in “real life.” Data from an online survey are analyzed using maximum likelihood procedures in LISREL 8.75 to test the structural model. Among 531 respondents from Cyworld, a popular social network and blogging site in South Korea, a randomly selected group of 251 users was used to develop the model. The other group of 280 users was used to confirm the usefulness of the revised model. Results (N=251; N=280) showed that impression management and voyeuristic surveillance are two major psychological factors that motivate individuals to post and read messages on personal blogs. Results also showed evidence for blogging’s real life consequences, measured by users’ perceived social support, loneliness, belonging, and subjective well-being.Accepted versio

Extrovert And Lonely Individuals’ Social Tv Viewing Experiences: A Mediating And Moderating Role Of Social Presence

Social TV viewing is generally understood as a simultaneous act of watching TV and engaging in communication about the TV program with other TV viewers connected online. In response to the increasing popularity of this new TV viewing practice, the current study examined how individuals’ extrovert personality and loneliness influence social TV viewing experiences through the theoretical notion of social presence. An online survey was completed by 330 individuals. Results demonstrated that extrovert personality positively influenced social TV viewing experiences; it is important to note that this relationship was mediated by social presence. Loneliness itself was negatively related to social TV viewing experiences; however, this relationship was moderated by social presence. Specifically, when lonely people felt strong social presence, they enjoyed social TV viewing experiences. The findings provide theoretical implications for social TV research, the dynamic role of social presence, social enhancement model, and social compensation model

Assessing Technologies for Information-Seeking on Prostate Cancer Screening by Low-Income Men

Purpose: This paper presents a multipart investigation of the benefits and challenges in deploying automated question-answering as an alternative to web-based searching to provide information about prostate cancer screening for low-income men age 40 years and older. Methods: The study comprised: 1) a survey assessing current use of the Internet, mobile phones and texting; 2) a controlled observational study of both web-based searching and automated question-answering for information about prostate cancer; and 3) a formative field study in which subjects interacted with a health department nurse using text messages. Results: Survey results suggest the target population has greater access to, and familiarity with, cell phones and text messaging compared to the Internet and web-based searching. Participants were significantly more confident using a cell phone and preferred to get health information through text messaging. Participants in the controlled observational study accepted the text messaging system, with most indicating it answered their questions, was easy to use and was a favorable tool for information-seeking. The field study also demonstrated potential for automated question-answering and text messaging to help the target population access health information. Conclusions: A two-way text messaging system has great potential to promote health communication and health information distribution. Participant interest in this system was high and did not seem to be specific to prostate cancer screening, suggesting that information about other topics, such as high blood pressure screening, could be provided similarly. We believe more investigations should be focused on this area, especially on benefits for the low-income community

Anti-smoking educational game using avatars as visualized possible selves

Few social smokers envision themselves being affected by the negative consequences of smoking despite well-known facts that smoking causes serious illnesses and death. However, as smoking habits quickly develop, social smokers cannot be free from the negative consequences of smoking. In this study, we pose the following question: “Would showing social smokers’ possible future as a consequence of smoking help them alter their current smoking behaviors?” Thus, using the theoretical concept of possible selves, an anti-smoking educational game was created in which players could see changes to the appearance of their future selves as a consequence of smoking. We used a 2 (Future face: Showing vs. Not showing) x 2 (Self avatar: Self-avatar vs. Other-avatar) between-subjects design for the experiment. Results indicated that participants who viewed the future face, compared to who did not, reported more negative attitudes toward social smoking and greater intention to quit smoking. The main effect of the self avatar was insignificant; however, seeing the future face in the self-avatar condition led to an increase in perceived risks compared to other-avatar condition. The implications of using avatars as visualized possible selves in health promotion are discussed.Accepted versio
