Social media have become an integral part of online news use, affecting how individuals find, consume, and share news. By applying the Theory of Reasoned Action (TRA), this study investigates the effects of motives, attitude, and intention on news-sharing behavior among German social media users (n = 333). Findings show that news-sharing attitude and subjective norms have a positive effect on news-sharing intention, which in turn has a positive effect on actual news-sharing behavior. Taken together, we see that a new media behavior in the early phases of its societal diffusion—like social media news sharing in Germany in 2015—can mainly be explained by a rational choice logic and is rooted in the motives of socializing and information seeking. This finding thus reflects the double nature of social media as a means for both information retrieval and social grooming.  相似文献

Social networking sites are considered a valuable resource to maintain existing friendships even over considerable distances. The present study emphasizes tie strength as a crucial determinant for the use of interactive and passive features among 302 active Facebook users and friends of different relational closeness (close friends vs. casual friends vs. acquaintances) as well as a moderator for the impact of physical distance. As expected, tie strength affected direct interaction linearly, whereas social surveillance followed a quadratic trend. Furthermore, moderation analyses revealed less frequent direct interaction between close friends and stronger surveillance of casual friends’ profiles as physical distance increases. These results indicate different functions in relationship maintenance for both behaviors as direct interaction aims at nurturing current relationships, while surveillance serves as a catalyst for promising future communications. As a consequence, physical distance influences direct interaction adversely due to emerging constraints but also contains informational value encouraging information-seeking behaviors.  相似文献

This session highlighted trends in continuing resource collections and collection management throughout the 30-year period from 1985 through 2015. Electronic resources became available in the 1990s and grew in prevalence from the 2000s through the present, changing the make-up of library collections and also how libraries measure collections and collection usage. Two librarians and two vendors shared their perspectives on these changes in collection development, describing how library collections now contain a combination of older formats and older ways of collecting data, and new, electronic content and automated ways of collecting and disseminating data about collections.  相似文献

Abstract

Many studies have found a relationship between students’ self-reported procrastination and their grades. Few studies have used learning analytic data as a behavioural measure of procrastination in order to predict performance, and there is no systematic research on how this relationship may differ across assessments or disciplines. In this study we analyse nine years’ worth of institutional electronic submission records, a total of 73,608 assignment submissions, to examine the relationship between submission time and grades across assignments, students, courses, and disciplines in higher education. A significant negative relationship was found overall, with students who submitted closer to the deadline obtaining lower grades, however the size of the relationship was negligible, accounting for less than 1% of the variance in grades. The relationship varied significantly depending on student, assignment, course and discipline.  相似文献

This paper provides an overview of the level of economic development in India, with a brief explanation of the factors that have impeded rapid growth of the economy. Against this background information, the paper focuses on some social programs undertaken by government and non-governmental agencies to help the most vulnerable segments of society to deal with the adverse effects of industrialization and urbanization and to share in the benefits of economic development.  相似文献

Children attending early childhood education and care centres spend a lot of time fitting in with institutional routines. This paper uses ethnographic methods and sociocultural activity theory to describe and analyse the processes whereby young children in an early childhood centre collectively created meaning and interest during potentially boring routine mealtimes. The research explores the relationship between rules and children's playful activity. Using their imaginations children negotiated and played with and within the rules around ‘eating‐together’ times. While physically constrained in chairs around tables children enjoyed the freedom of playing with word sounds and meanings. Children actively, collaboratively and at times subversively, created their peer community culture.  相似文献

ABSTRACT

In this article, I question practice as a research paradigm by exploring its position in relation to non-positivist qualitative methodologies. Frayling’s [1994. Research in art and design. Royal College of Art Research Papers, 1(1), 1993/4] distinctions between research into, through, and as (for) practice are expanded to explore overlaps between these approaches. I argue for the need to understand the nuances of different epistemologies and ontologies that underpin diverse disciplinary approaches to practice-research. This is done through an analysis of a selection of Arts and Humanities Research Council (AHRC)-funded projects to find out how they are using and/or embedding practice in the research process. The resulting Colour Wheel of Practice-Research illustrates a spectrum of positions of practice in relation to research, suggesting existing research paradigms are bursting at the seams and that the “disciplinary matrix” of practice might offers other ways of knowing. The reason I have chosen to focus primarily on AHRC-funded projects is because it explicitly states its support of “practice-led research” and that it “remains dedicated to this area of research”. This article aims to add to knowledge of how and why practice-research is of continuing interest to research councils, universities, and those identifying as practice-based/led researchers.  相似文献
