The reflection of offline activities on users’ online social behavior: An observational study

The ever increasing presence of online social networks in users’ daily lives has led to the interplay between users’ online and offline activities. There have already been several works that have studied the impact of users’ online activities on their offline behavior, e.g., the impact of interaction with friends on an exercise social network on the number of daily steps. In this paper, we consider the inverse to what has already been studied and report on our extensive study that explores the potential causal effects of users’ offline activities on their online social behavior. The objective of our work is to understand whether the activities that users are involved with in their real daily life, which place them within or away from social situations, have any direct causal impact on their behavior in online social networks. Our work is motivated by the theory of normative social influence, which argues that individuals may show behaviors or express opinions that conform to those of the community for the sake of being accepted or from fear of rejection or isolation. We have collected data from two online social networks, namely Twitter and Foursquare, and systematically aligned user content on both social networks. On this basis, we have performed a natural experiment that took the form of an interrupted time series with a comparison group design to study whether users’ socially situated offline activities exhibited through their Foursquare check-ins impact their online behavior captured through the content they share on Twitter. Our main findings can be summarised as follows (1) a change in users’ offline behavior that affects the level of users’ exposure to social situations, e.g., starting to go to the gym or discontinuing frequenting bars, can have a causal impact on users’ online topical interests and sentiment; and (2) the causal relations between users’ socially situated offline activities and their online social behavior can be used to build effective predictive models of users’ online topical interests and sentiments.  相似文献   

Photovoice as a research method for higher education research

ABSTRACT

Higher education (HE) research often draws on a range of qualitative research approaches. However, some methods developed in other fields are underutilised in HE research, even though they could be of great use for answering particular kinds of research questions, or for involving students more actively in the research process. In this article, we draw on a study that piloted different methodological approaches to explore students’ conceptions of good teaching and effective learning at university. The participants in our study included 33 high achieving international, Māori, Pacific Island, and (other) local students enrolled in Humanities subjects. Our study used photovoice as a visual data collection approach in conjunction with more traditional methods of data collection: open-ended focus group questions and critical incident technique. In this article, we review the photovoice literature, which is mostly from outside HE. Then, we describe our study, discussing the students’ responses to photovoice, and the different kinds of data it elicited. We note that, while most students expressed appreciation of the photovoice approach, some also found it restrictive and challenging in some respects. We conclude, photovoice offers a useful methodological addition to HE research, while noting, as with all data collection approaches, researchers need to be mindful of its limitations.  相似文献   

Public deliberation and social justice sensibilities in Greensboro Participatory Budgeting     

Vincent Russell  Spoma Jovanovic 《传播与批判/文化研究》2020,17(2):111-128

ABSTRACT

Participatory budgeting (PB) has emerged as a tool for empowering marginalized communities and advancing social justice through public deliberation and advocacy. However, public deliberation scholars have contested the appropriate roles of social justice, activism, and equity. PB bridges deliberation, advocacy, and equity, as it strives to accomplish social change. We detail how the first cycle of Greensboro PB navigated tensions between residents who sought social change and government officials who wished to maintain the status quo. We argue PB is an example of public deliberation that fosters social justice sensibilities among participants and conclude with applied recommendations for design improvements.  相似文献

Research agenda for social and collaborative information seeking     

Chirag Shah  Rob Capra  Preben Hansen 《Library & information science research》2017,39(2):140-146

Scholars in diverse fields of inquiry have identified the need to expand individual-based information seeking and behavior models and systems to incorporate social as well as collaborative dimensions. However, the research areas of Social Information Seeking (SIS) and Collaborative Information Seeking (CIS) have been largely disconnected from one another despite a few notable attempts to study them under one umbrella. Researchers in these communities have recently realized the value of bringing SIS and CIS together for two main reasons: often it is impossible to separate social and collaborative dimensions in a project; and by considering these two aspects of information seeking, we may be able to support human information behavior in ways not previously possible. A brief synthesis of work in the domains of SIS and CIS is presented here. Then, an integrated view is presented to consider Social and Collaborative Information Seeking (SCIS) as an intersection and extension of SIS and CIS. Benefits of this approach are discussed and the integrated view is used as the basis to present a research agenda that outlines opportunities and challenges unique to SCIS.  相似文献   

Constructing and experiencing boyhoods in research in London   总被引：1，自引：1，他引：1  

Rob Pattman  Stephen Frosh  Ann Phoenix 《Gender and education》2005,17(5):555-561

When Rob was about 14‐years‐old, at an all male boarding school, he was so glad that he did not have a tiny penis like another boy who was called girl. He was popular because he was good at sport, missed his mum and dog terribly but never showed it (except a little to his mum and dog) and talked a lot about girls he fancied. These memories were triggered by an interview based study on the identities of 11‐ to 14‐year‐old boys in London which we conducted from 1997–2000. Rob was the interviewer, and he interviewed boys in groups (45: 36 single sex and nine mixed) and individually (79) in 12 London schools.  相似文献   

Mechanisms underlying reductions in stroke volume at rest and during exercise at high altitude     

Mike Stembridge  Philip N. Ainslie  Rob Shave 《European Journal of Sport Science》2016,16(5):577-584

High-altitude exposure challenges the cardiovascular system to maintain oxygen delivery to the mitochondria under conditions of hypoxic stress. Following acclimatisation (3–5 days), stroke volume (SV) falls to below sea-level values but heart rate remains elevated, such that cardiac output is maintained compared to sea level. The decrease in SV has been a topic of research for over 40 years, but the underlying mechanisms are incompletely understood. Impaired systolic contractile function secondary to reduced coronary arterial oxygen tension has been investigated as a potential cause for the decrease in SV. However, despite in vitro evidence of impaired cardiac contractile force in severe hypoxia, the majority of studies to date have reported enhanced in vivo ventricular systolic function at rest and during exercise in humans up to and above 5000?m. However, the elevated function observed at rest has recently been suggested to reduce the functional reserve available during exercise. While in vivo systolic function appears enhanced at high altitude, a decrease in left ventricular end-diastolic volume (EDV) and altered filling patterns of both ventricles has been observed. The reduction in ventricular filling will undoubtedly affect SV, and four potential mechanisms have been proposed to explain the reduction in left ventricular filling. In this article, both historical and recent reports of systolic function at high altitude will be reviewed, and evidence supporting and refuting each of the four mechanisms underpinning reduced left ventricular filling will be discussed.  相似文献
