Self-tracking has attracted a lot of attention from researchers and public opinion makers owing to its potential for improving life conditions through preemptive action on health, and as a tool of user empowerment vis-à-vis health-care professionals and private and public institutions. Nevertheless, the ‘stuff’ that is typically tracked – exercise and diet being the dominant tracking activities – refers to cultural and social practices that, for the individual user, are utterly mundane and reside in an experiential realm of everyday life. Self-tracking has to be understood in relation to behavior that is predominantly about getting things done in ways that are possible, suitable and meaningful for the individual. To account for this, we propose to conceptualize self-tracking as a communicative phenomenon along three dimensions: communication with the system, the self and social networks of peers. We develop the theoretical framework, drawing upon empirical findings from a qualitative study on how self-tracking is practiced and experienced in the context of exercise by different categories of empirical users. We demonstrate that the meanings of self-tracking practices are, at once, shaped by the motivation of an individual user who is situated in a broader web of everyday activities, and stimulated and augmented by communicative features provided by the technology. 相似文献

This objective of this research was to determine factors influencing counselor educators’ behavioral intentions to teach counseling students about mental health mobile applications (MHMAs), factors influencing values of MHMAs as therapeutic tools, and to what extent counselor education programs are contributing to future counselors’ technological competence with regard to evaluating and integrating MHMAs. The conceptual basis was a theory triangulation approach using theories of technology use and acceptance and diffusion of innovations. Nine quantitative, two qualitative, and two mixed methods research questions served to guide the study. Participants were 132 faculty members from 99 university counseling programs. Participants completed an initial survey, an evaluation of an evidence-based mental health mobile application (app), and a postmeasure. Hierarchical multiple regression, analysis of covariance (ANCOVA), independent samples t-tests, and paired samples t-tests were used to analyze quantitative data. Results indicated that unified theory of acceptance and use of technology (UTAUT) variables along with anxiety/apprehension and ethical concerns are related to behavioral intentions to teach students about MHMAs. Semistructured video interviews were conducted and analyzed in the qualitative phase to add depth and explain quantitative findings. This study has implications for graduate counselor education programs and related accrediting agencies. 相似文献

Technology-Based Interventions and Trainings to Reduce the Escalation and Impact of Alcohol Problems

There has been a rapid increase in the development of technological innovations to reduce the escalation and impact of alcohol problems among adolescents and adults. Technology-based interventions offer the possibility of reaching individuals who otherwise might not seek treatment, (e.g., those in remote areas, those not perceiving a need for treatment, or others who might resist treatment). This article describes 4 case examples of technology-based interventions for risky drinking: (a) a freely available and interactive Web site that provides individualized feedback and information on risky drinking patterns; (b) a brief intervention for adolescents that provides individualized feedback to teens regarding their alcohol use; (c) a computer-delivered screening and brief intervention for alcohol use among pregnant women; and (d) a simulation program for training social workers in screening and brief intervention. These case examples highlight how technology could have a role in addressing the Alcohol Misuse Grand Challenge. 相似文献

服务商增值战略匹配已超出单一企业的范畴,有必要进行基于价值链环境的跨企业决策。为实现基于价值链环境的增值战略匹配,以价值链均衡为优化目标,建立受当前决策变量状态约束的优化模型。针对信息不完全条件下的动态多目标优化问题,提出实证关系驱动的定性模拟进行求解。扩展传统战略匹配模型(SAM)至信息不完全的价值链环境中,抽象出优化模型描述。以增值战略匹配为研究对象,设计了问卷,利用ANP方法获取决策变量之间的关系。通过QSIM算法驱动因素间交互关系的动态演化,确定实现价值链增值战略均衡时的最佳决策变量组合。算例分析表明了该模型和算法的有效性,能为移动增值战略的实时优化决策提供支持。根据计算结果可以确定战略要素的发展优先级,从而实现资源的优化配置。 相似文献

Digital technologies have given rise to increased occurrences of self-surveillance and forms of 'virtual vigilantism'. This has progressed from key moments such as the video recording of the Rodney King incident, to recording human rights abuses, to citizen grassroots surveillance. From this has emerged the phenomenon known as citizen journalism where recent urban crises have been recorded on mobile phones by the individuals involved. Also on the increase are forms of mob vigilantism, or 'participatory panopticon'; examples here include phone images spread over the Internet as severe forms of 'community punishment'. I argue that these unmediated forms of bottom-up surveillance – sousveillance – show the early signs of a new type of civil responsibility that stands unregulated and without restraint. This paper addresses the issues of increased individualised self-surveillance and asks whether this is the consequence of a personalised resistance to an ever increasing surveillance society. 相似文献
