A Question of Identity 
Life on the Screen is a fascinating and wide-ranging investigation of the impact of computers and networking on society, peoples' perceptions of themselves, and the individual's relationship to machines. Sherry Turkle, a Professor of the Sociology of Science at MIT and a licensed psychologist, uses Internet MUDs (multi-user domains, or in older gaming parlance multi-user dungeons) as a launching pad for explorations of software design, user interfaces, simulation, artificial intelligence, artificial life, agents, "bots," virtual reality, and "the on-line way of life." 
Turkle's discussion of postmodernism is particularly enlightening. She shows how postmodern concepts in art, architecture, and ethics are related to concrete topics much closer to home, for example AI research (Minsky's "Society of Mind") and even MUDs (exemplified by students with X-window terminals who are doing homework in one window and simultaneously playing out several different roles in the same MUD in other windows). Those of you who have (like me) been turned off by the shallow, pretentious, meaningless paintings and sculptures that litter our museums of modern art may have a different perspective after hearing what Turkle has to say. 
This is a psychoanalytical book, not a technical one. However, software developers and engineers will find it highly accessible because of the depth of the author's technical understanding and credibility. Unlike most other authors in this genre, Turkle does not constantly jar the technically-literate reader with blatant errors or bogus assertions about how things work. Although I personally don't have time or patience for MUDs,view most of AI as snake-oil, and abhor postmodern architecture, I thought the time spent reading this book was an extremely good investment.

Agency over social media use can be enhanced through brief abstinence, but only in users with high cognitive reflection tendencies

This study theorizes on and examines the impact of social networking sites (SNS) use on health outcomes in adolescents. By using data from the 2015-16 sweep of the Millennium Cohort Study, SNS use and its effects on sleep duration, healthy eating (fruits/vegetables intake, eating breakfast), and self-rated health was evaluated in 11,406 adolescents (13–15 years old). For this, a model was constructed and tested with the PROCESS macro in SPSS. Daily SNS use time was found to be negatively associated with general health; and this effect was fully mediated through decreased sleep duration and reduced healthy eating. Females had a higher risk of being negatively affected by the extent of their SNS use, compared to males. These findings contribute to the understanding of potential social media use effects on adolescents. They further show that established sex differences in sleep hygiene and healthy eating, which have been explained from the psychological and physiological perspective in prior research, can also stem, in part, from differences in social media use patterns. From a practical standpoint, strategies aimed at helping adolescents manage their sleep hygiene and healthy food intake despite their SNS use may be more fruitful than those aimed at assisting them to curb their social media use.

Technology addiction is a relatively new, but important, concept that has not yet been well integrated into mainstream IS models. This study bridges this gap, and integrates technology addiction and technology adoption in the context of online auction websites. The findings of an empirical study of 132 eBay users indicate that addiction to online auction websites augments user perceptions of the usefulness and enjoyment attributed to the technology, which in turn influence future usage. Post-hoc analysis further indicates that addiction is not a proximal concept, and as such, it affects future usage through key system-referenced perceptions. Implications of the findings are discussed.

Integrating Technology Addiction and Adoption: An Empirical Investigation of Online Auction Websites.

Purpose: Electronic waste (e-waste) such as discarded computers and smartphones may contain large amounts of confidential data. Improper handling of remaining information in e-waste can, therefore, drive information security risk. This risk, however, is not always properly assessed and managed. The authors take the protection motivation theory (PMT) lens of analysis to understand intentions to protect one's discarded electronic assets. Design/methodology/approach: By applying structural equation modeling, the authors empirically tested the proposed model with survey data from 348 e-waste handling users. Findings: Results highlight that (1) protection intention is influenced by the perceived threat of discarding untreated e-waste (a threat appraisal) and self-efficacy to treat the discarded e-waste (a coping appraisal) and (2) optimism bias plays a dual-role in a direct and moderating way to reduce the perceived threat of untreated e-waste and its effect on protection intentions. Originality/value: Results support the assertions and portray a unique theoretical account of the processes that underline people's motivation to protect their data when discarding e-waste. As such, this study explains a relatively understudied information security risk behavior in the e-waste context, points to the role of optimism bias in such decisions and highlights potential interventions that can help to alleviate this information security risk behavior.

The purpose of this paper is to validate empirically a theoretical model that integrates an innovative construct capturing consumers’ non-adoption risk belief associated with not using a mobile service designed to support them in a non-leisure activity.,A theoretical model contrasting perceived non-adoption risk to perceived adoption risk of a mobile service supporting health promotion was developed and tested with a sample of potential consumers in North America.,Results show that non-adoption risk is a moderately strong antecedent of motivational factors in contrast to adoption risk that hinders the acceptance of a mobile service supporting health promotion.,Healthcare is a highly sensitive social sector, so possible negative consequences of not using the support of a mobile service are an additional motivation for adopting this service. Future research should test the role of non-adoption risk in other contexts of technology use, including non-leisure settings.,Making potential users see the possible negative consequences of not using a mobile service designed to support them in a non-leisure activity increases their motivation and, subsequently, intention to use the service.,Educational efforts to making consumers see the risks of not using a supporting technology application appear to be justified.,This study demonstrates the significant role of non-adoption risk belief that captures the negative consequences individuals may perceive if they fail to use as expected a mobile service application designed specifically to help them.
