This article explains Internet users’ self-help activities in protecting their privacy online using structural equation modeling. Based on a representative survey of Swiss Internet users, it reveals past experiences with privacy breaches as a strong predictor of current protective behavior. Further, in line with the ‘privacy paradox’ argument, caring about privacy (privacy attitudes) alone does not necessarily result in substantial self-protection. Most strikingly, however, general Internet skills are key in explaining users’ privacy behavior. These skills enable users to reduce risks of privacy loss while obtaining the benefits from online activities that increasingly depend on the revelation of personal data. Consequently, Internet skills are an essential starting point for public policies regarding users’ self-help in privacy protection.  相似文献

This paper provides a response to the commentary by Delfabbro and King (2017), which describes major criticisms of articles situated in a ‘political economy’ conceptual framework. The current paper argues that these criticisms obfuscate legitimate concerns about industry involvement in gambling research, and disregard important evidence about activities of hazardous-consumption industries which provide grounds for strong concern about commercial practices of the gambling industry. Although many aspects of the commentary by Delfabbro and King (2017) are contentious, the current paper summarizes conceptual and empirical literature which supports concern about (a) agency and collaboration in practices of the gambling industry, which make assertions of equivalence with a conspiracy theory both inappropriate and misleading, and (b) the role of research on problem gambling behaviours and pathologies in supporting agendas that may undermine public health. This indicates the need for the scientific community to take seriously its role in improving awareness of the hazards of commercial involvement in gambling research, and thus helping researchers to make informed decisions about these risks and their own manner of engagement with the gambling industry.  相似文献

The scientific literature stresses the importance of culture and social environment in determining what people think about alcohol consumption and consequently do. Several pieces of research have proved the influence on young adults’ alcohol use of proximal social contexts of their family and peers. The present study aimed at investigating the influence of family behaviours and norms compared to the peers’ influence in a context where the culture of alcohol is changing between the different generations. Data were collected by means of a self-report questionnaire on a sample of 598 young adults (average age 22.20 years). The variables investigated were socio-demographic characteristics, the alcohol consumption of parents and friends and the parents’ and peers’ approval of alcohol consumption. The results confirmed the role of family and friends in influencing young adults’ consumption of alcohol, stressing a difference between perceived behaviours and norms. The perceived consumption of parents and friends influenced the participants’ consumption. On the contrary, the effects of the approval of drinking were limited. Globally friends had a stronger influence on alcohol consumption in comparison with family.  相似文献

Problem

Pacific Islanders are disproportionately burdened by poorer maternal health outcomes with higher rates of pre-term births, low birth weight babies, infant mortality, and inadequate or no prenatal care.

Purpose

The purpose of this study was twofold: (1) to explore maternal health care providers’ perceptions and experiences of barriers in providing care to Marshallese women, and (2) providers perceived barriers of access to care among Marshallese women. This is the first paper to explore perceived barriers to maternal health care among a Marshallese community from maternal health care providers’ perspectives in the United States.

Methods

A phenomenological, qualitative design, using a focus group and in-depth interviews with 20 maternal health care providers residing in northwest Arkansas was chosen.

Findings

Several perceived barriers were noted, including transportation, lack of health insurance, communication and language, and socio-cultural barriers that described an incongruence between traditional and Western medical models of care. There was an overall discord between the collectivist cultural identity of Marshallese families and the individualistic maternal health care system that merits further research.

Discussion

Solutions to these barriers, such as increased cultural competency training for maternal health care providers and the incorporation of community health workers are discussed.  相似文献

Background

Prenatal health promotion provides information regarding pregnancy risks, protective behaviours and clinical and community resources. Typically, women obtain prenatal health information from health care providers, prenatal classes, peers/family, media and increasingly, Internet sites and mobile apps. Barriers to prenatal health promotion and related services include language, rural/remote location, citizenship and disability. Online public health platforms represent the capacity to reach underserved women and can be customised to address the needs of a heterogeneous population of pregnant women.

Aim

Canadian government-hosted websites and online prenatal e-classes were evaluated to determine if accessible, inclusive, comprehensive and evidence-based prenatal health promotion was provided.

Methods

Using a multijurisdictional approach, federal, provincial/territorial, municipal and public health region-hosted websites, along with affiliated prenatal e-classes, were evaluated based on four criteria: comprehensiveness, evidence-based information, accessibility and inclusivity.

Findings

Online prenatal e-classes, federal, provincial/territorial and public health-hosted websites generally provided comprehensive and evidence-based promotion of essential prenatal topics, in contrast to municipal-hosted websites which provided very limited prenatal health information. Gaps in online prenatal health promotion were identified as lack of French and multilingual content, targeted information and representations of Indigenous peoples, immigrants and women with disabilities.

Conclusion

Canadian online prenatal health promotion is broadly comprehensive and evidence-based, but fails to address the needs of non-Anglophones and represent the diverse population of Canadian pregnant women. It is recommended that agencies enhance the organisation of website pregnancy portals/pages and collaborate with other jurisdictions and community groups to ensure linguistically accessible, culturally-competent and inclusive prenatal online resources.  相似文献

This study, based on a survey of 489 documentary filmmakers, is a case study in copyright policy in and through practice. It assesses the changes in documentary production practice around clearance of copyrighted material since the creation of the Documentary Filmmakers' Statement of Best Practices in fair use in 2005. Fair use, an exotic and occasional feature of documentary film in 2004, has become well known and commonly employed. Creative options for filmmakers concerning the use of third-party material have dramatically improved with changes in norms after the issuing of the Statement. Attitudes about fair use are strongly associated with free expression and creative opportunity, and vary with experience. Where filmmakers have changed work because of copyright concerns, they themselves rather than any gatekeeper have made the decision to do so. Where change is associated with fair use, risk is a common concern. Newer filmmakers are more likely to support the use of copyrighted material to make new work, but less likely to know about fair use, and also more likely to have experienced takedowns online. Both education about and experience with fair use appear to have an effect on practice. Filmmakers continue to lack reliable information on the actual risk landscape, and about fair use on digital platforms.  相似文献

Temporality is fundamental to qualitative longitudinal (QLL) research, inherent in the design of returning to participants over time, often to explore moments of change. Previous research has indicated that talking about the future can be difficult, yet there has been insufficient discussion of methodological developments to address these challenges. This paper presents insights from the Energy Biographies project, which has taken a QLL and multimodal approach to investigating how everyday energy use can be understood in relation to biographical pasts and imagined futures. In particular, we detail innovative techniques developed within the project (e.g. SMS photograph activities) to elicit data on anticipated futures, in ways that engender thinking about participants’ own biographical futures and wider societal changes. We conclude by considering some of the significant benefits and challenges such techniques present. These methodological insights have a wider relevance beyond the substantive topic for those interested in eliciting data about futures in qualitative research.  相似文献

In China, the implementation of a Danmaku social media system to sustain and raise user interest in online video sites is an increasingly widespread phenomenon. Danmaku technology is used to display users’ messages in written text on the online video stream. Little is known about the effects of this form of interactive enhancement. The aim of this empirical study is to evaluate the evolving media capabilities of the Danmaku system and their effects on users’ perceptions of interactivity and their intentions to continue using Danmaku. We draw on media synchronicity theory and apply it to a stimulus-organism-response model. Using this framework, we hypothesize that the media capabilities of the Danmaku system, namely its transmission velocity, parallelism, symbol sets, rehearsability, and reprocessability, elicit increased interactivity, which influences users’ instantaneous intentions to share and to continue the use of the Danmaku system. The results showed that both users’ instantaneous intention to share and their intention to continue to use were significantly affected by the perceived interactivity. Unlike the results of previous studies, our findings showed that all five media capabilities positively affected the users’ perceptions of interactivity. The potential theoretical and practical implications of our findings are discussed.  相似文献

The present study advances research on union status and health by providing a first look at alcohol use differentials among different‐sex and same‐sex married and cohabiting individuals using nationally representative population‐based data (National Health Interview Surveys 1997–2011, N = 181,581). The results showed that both same‐sex and different‐sex married groups reported lower alcohol use than both same‐sex and different‐sex cohabiting groups. The results further revealed that same‐sex and different‐sex married individuals reported similar levels of alcohol use, whereas same‐sex and different‐sex cohabiting individuals reported similar levels of alcohol use. Drawing on marital advantage and minority stress approaches, the findings suggest that it is cohabitation status—not same‐sex status—that is associated with elevated alcohol rates.  相似文献

Contemporary expectations of good parenting hold that focused, intensive parental attention is essential to children's development. Parental input is viewed as a key determinant in children's social, psychological and educational outcomes, with the early years particularly crucial. However, increased rates of maternal employment mean that more parents are juggling work and family commitments and have less non‐work time available to devote to children. Yet studies find that parental childcare time has increased over recent decades. In this paper, we explore the detail of this trend using data from the Australian Bureau of Statistics (ABS) Time Use Survey (TUS), 1992 and 2006. To investigate whether discourses on intensive parenting are reflected in behaviour, we examine a greater range of parent–child activities than has been undertaken to date, looking at trends in active childcare time (disaggregated into talk‐based, physical and accompanying care activities); time in childcare as a secondary activity; time spent in the company of children in leisure activities; and time spent in the company of children in total. We also investigate whether the influence of factors known to predict parental time with children (gender, education, employment status and the age of children) have changed over time. We contextualize our analyses within social and economic trends in Australia and find a compositional change in parental time, with more active childcare occurring within less overall time, which suggests more intensive, child‐centred parenting. Fathers' parent–child time, particularly in physical care, increased more than mothers' (from a much lower base), and tertiary education no longer predicts significantly higher childcare time.  相似文献
