Abstract

Australia is experiencing a period of immense cultural change predicated on the use of Information and Communication Technology (ICT). New devices such as smartphones, tablet computers, and the social iterations of the internet are impacting on communication patterns and contributing to the merging of people's online and offline lives. Using Spanish sociologist Manuel Castells's theory of the Network Society as a theoretical foundation, this issues paper posits that social work must overcome its historical reluctance to embrace ICT if it is to remain relevant in the era of the network society. In particular, we argue that social work professionals need to begin a dialogue with IT developers, social service managers, and funding bodies about the need for practice-led ICT systems. This paper examines the turbulent history social work has had with technological change, and concludes that the adoption of a practice-led approach to ICT use in education, practice, and research provides a strong foundation for reimagining the relationship between social work and ICT.  相似文献

Abstract

Objective: To examine the efficacy of a self-affirmation task in deterring college alcohol misuse and the importance of preexisting beliefs in predicting subsequent behavior change. Participants: Heavy-drinking undergraduates (N = 110) participated during the 2011–2012 academic year. Methods: Participants were randomized to complete an affirmation or control task before reading an alcohol risk message. Alcohol-related beliefs and behaviors were assessed. Participants completed a 2-week online follow-up assessing alcohol-related behaviors. Results: Both groups reported increased perceived problem importance, but neither group displayed changes in personal risk. Follow-up assessment revealed similar, significant declines in peak consumption in both groups, with no significant between-group differences. Preexisting beliefs accounted for 5% to 10% of variance in drinking outcomes. Conclusions: An affirmation task does not seem to decrease defensive processing or alter high-risk drinking behaviors among college students and should not be utilized in lieu of more effective strategies.  相似文献

Abstract

Objectives: This exploratory study examined pre-event drinking, or pregaming, by US college students. Participants: 112 undergraduates from 10 Pennsylvania colleges participated. Method: A focus group, including a written questionnaire, was conducted at each institution. Results: Only 35.7% of the participants had not pregamed during the last 2 weeks. Pregamers consumed an average of 4.9 (SD = 3.1) drinks during their most recent session. Gender, class year, and other demographic variables did not predict pregaming. Heavier drinkers, and those stating that the average student pregamed 3+ times in the last 2 weeks, were more likely to report pregaming in the last 2 weeks. How much students drink when pregaming is influenced by how much they expect to drink later on. Conclusion: Pregaming presents a growing challenge for campus officials. Additional research is needed on the nature of the problem and which combination of prevention strategies might best address this behavior.  相似文献

While studies have shown that adults use smoking to deal with stress, little research has been carried out with children to explore their perceptions of smoking as a coping strategy. Qualitative questionnaire and interview data were generated with children aged 9–11 years. Participants perceived that adults smoked to relieve boredom and stress, and suggested that children might smoke for the same reasons. Children were more likely to know that adults smoked to deal with stress if they lived in a deprived area. Girls were more likely to believe that some children need to smoke as a coping strategy.  相似文献

Forty individuals from the American Red Cross were interviewed to explore the use of social media in communicating with key publics. Results show that practicing public relations through social media is effective and necessary in the emerging digital age, as shown through the Red Cross’ development of a two-way dialogue with younger constituents, the media, and the community. This two-way dialogue has been accomplished primarily through Twitter and Facebook, with barriers such as lack of staff and time, and opportunities to improve National Headquarters and local chapter relations. The insights shared by the American Red Cross are useful for both public relations scholars and professionals to help them understand and apply social media practices to build strong, lasting relationships.  相似文献

Abstract

The resuscitation of deliberative democracy in the Information Age requires the construction of transparent public spaces ‐ public arenas where power relationships between speakers are discernible and debate ensues according to the rules of civility and reason (conversational transparency). The metaphor of transparency, in the sense of legal accountability, also connects the role of communications regulation to the development of democratic political culture (legal transparency). Finally, transparency suggests the power of technology to obscure and hinder as well as help the progress of deliberative democracy (technological transparency).  相似文献

Summary.  Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder which is most often diagnosed in childhood with symptoms often persisting into adulthood. Elevated rates of substance use disorders have been evidenced among those with ADHD, but recent research focusing on the relationship between subtypes of ADHD and specific drugs is inconsistent. We propose a latent transition model (LTM) to guide our understanding of how drug use progresses, in particular marijuana use, while accounting for the measurement error that is often found in self-reported substance use data. We extend the LTM to include a latent class predictor to represent empirically derived ADHD subtypes that do not rely on meeting specific diagnostic criteria. We begin by fitting two separate latent class analysis (LCA) models by using second-order estimating equations: a longitudinal LCA model to define stages of marijuana use, and a cross-sectional LCA model to define ADHD subtypes. The LTM model parameters describing the probability of transitioning between the LCA-defined stages of marijuana use and the influence of the LCA-defined ADHD subtypes on these transition rates are then estimated by using a set of first-order estimating equations given the LCA parameter estimates. A robust estimate of the LTM parameter variance that accounts for the variation due to the estimation of the two sets of LCA parameters is proposed. Solving three sets of estimating equations enables us to determine the underlying latent class structures independently of the model for the transition rates and simplifying assumptions about the correlation structure at each stage reduces the computational complexity.  相似文献
