Knowledge-intensive systems in the social service agency: Anticipated impacts on the organisation

Shrinking resources and the increasing complexity of clinical decisions are stimulating research in knowledge-intensive computer applications for the delivery of social services. The expected benefits of knowledge-intensive applications such as expert systems include improvement in both the quality and the consistency of service delivery, augmentation of institutional memory, and reduced labour costs through greater reliance on paraprofessionals. This paper analyses the likely impacts of knowledge-intensive systems on social service organisations, drawing on trends in related service-delivery fields, and on known impacts of computer applications in organisations. A structural change may be anticipated: decision making and planning functions will shift increasingly from social service professionals to administrators.     

Social security administration's progress in modernizing its computer operations

This review of the Social Security Administration's information processing efforts by the GAO offers an interesting update to some of the earlier articles that appeared in SOS about Social Security. It appears from the report that progress is being made. However, there have been some changes in a plan that was to result in major improvements in systems at SSA.In particular, the GAO has found the SS Administration does not plan to document existing systems before proceeding with the design of new applications. The investigators are concerned that it will be difficult to develop good specifications if present designs are not documented. On the side of the Administration is the fact that tremendous resources are needed to document existing systems that may be mostly abandoned when new ones are implemented.This discussion of software engineering and design philosophy mirrors what is happening in other organizations faced with the need to make major redesigns of existing applications.     

Effect of physico-chemical factors and semi-synthetic media on vegetative growth of Lentinus subnudus (Berk.), an edible mushroom from Nigeria

Attempts were made to investigate the effect of different semi-synthetic growth media, pH, temperature, carbon and nitrogen compounds, as well as additives, on vegetative growth of L. subnudus (Berk.), an edible mushroom from Nigeria. The best mycelial extensions (92.7 and 92. mm) were obtained on potato dextrose agar (PDA) and yellow corn agar (YCA), respectively. Moderate growths (87.0, 85.0 and 80.0 mm) were observed on white corn agar (WCA), yeast extract agar (YEA) and malt extract agar (MEA), respectively, but least growth (38.6 mm) was recorded on ‘Ife brown’ beans agar (IBBA). This fungus grew within a temperature range of 15–40 °C (optimum 30 °C) and, pH range of 5.0–8.0 (optimum 5.5).     

Editorial.

In the 6 years since the Journal of Personality and Social Psychology was divided into three sections, Interpersonal Relations and Group Processes (IRGP) has come to be the impoverished sibling in the family. This weakness seems curious in a discipline that concentrates on human interrelatedness as its central theme. Indeed, Gordon Allport's definition in the Handbook of Social Psychology (1968) acknowledged the social core of social psychology: "an attempt to understand and explain how the thoughts, feelings and behaviors of individuals are influenced by the actual, imagined or implied presence of others." Perhaps the short rations to which many readers have become accustomed reflected a reluctance of researchers to engage these phenomena in the individualistic Zeitgeist of the 1970s and early 1980s. Nevertheless, 1986 brings a renewed interest in the scientific study of human social bonds. It is to the dissemination of the very best of this work that this editorship is dedicated.

Civil liability for misuse of online communication through websites: an analytical study of UAE law

ABSTRACT

This paper takes the UAE legal system as case in point to illustrate certain challenges posed for jurists by the spread of the Internet. Since it enables large-scale participatory multimedia content production, the Internet is surrounded by regulatory safeguards for ensuring its public accountability. In the UAE, the National Media Council holds responsibility for licensing media outlets, including online ones, and for overseeing content published therein. Together, legal disciplines on content, regulatory accountability frameworks and the collaborative nature of Internet content production form the context in which existing regimes, such as for civil liability (tort), call for interpretive adaptation. This is what this paper undertakes, with respect to civil liability claims for misuse of online communication through websites. A close analytical study of UAE law helps clarify how civil liability is established and apportioned between the National Media Council (vicarious liability), media outlets and individual users, alongside other findings.     

Social presence in relation to students' satisfaction and learning in the online environment: A meta-analysis

Social presence, the ability to perceive others in an online environment, has been shown to impact student motivation and participation, actual and perceived learning, course and instructor satisfaction, and retention in online courses; yet very few researchers have attempted to look across contexts, disciplinary areas, or measures of social presence. This meta-analysis allowed us to look across these variables of the primary studies and identify the pattern of student outcomes (e.g., perceived learning and satisfaction) in relation to social presence through scrutiny of differences between the studies. The results showed a moderately large positive average correlation between social presence and satisfaction (r = 0.56, k = 26) and social presence and perceived learning (r = 0.51, k = 26). Large variation among correlations (86.7% for satisfaction and 92.8% for perceived learning, respectively) also indicated systematic differences among these correlations due to online course settings. We found that (a) the strength of the relationship between social presence and satisfaction was moderated by the course length, discipline area, and scale used to measure social presence; and (b) the relationship between social presence and perceived learning was moderated by the course length, discipline area, and target audience of the course. Implications and future research are discussed.     

Examining the spillover effect of sustainable consumption on microloan repayment: A big data-based research

Social value-oriented consumers perform more sustainable consumption than conventional consumers do because consumers’ choices reflect their latent social values on environmental protection. However, whether sustainable consumption prompts more social value-oriented behaviors outside the consumption domain remains uncertain. The increased availability of consumer-level big data presents an opportunity to investigate consumers’ cross-domain behavior subsequent to sustainable consumption, which broadens the comprehension of sustainable consumption by going beyond the boundary of consumption behavior. Supported by a joint dataset comprising information on both consumers’ consumption behavior and their microloan repayment behavior, this study examines the effects of sustainable consumption on consumers’ subsequent debt default behavior to empirically test the cross-domain spillover effects of sustainable consumption behavior. The results suggest that the default probability of green consumers overall was 4.34 % lower than that of nongreen consumers, even though this positive effect on repayment disappears when sustainable consumption is for health reasons. The findings contribute to research on sustainable consumption by providing empirical evidence indicating that sustainable consumption has positive spillover effects in other domains. The results also provide an alternative perspective for identifying high-quality borrowers for microloan platforms.     

Personality and selfies: Narcissism and the Dark Triad

Selfies, or pictures taken of oneself and shared on social media, have become a worldwide phenomenon. In the present research, we examine the relationship between narcissism, both vulnerable and grandiose, and the frequency of and motivations behind selfie-taking. The Dark Triad of personality (narcissism, psychopathy, and Machiavellianism) and self-esteem were also measured. In Study 1, 348 adults on Amazon Mturk completed measures of personality, demographics, and several questions about selfie behavior online. In Study 2, 491 undergraduate students completed the same measures and a subset of these provided access to their Instagram and Iconosquare accounts, which were rated for narcissism by naive judges. Results from both studies indicate that grandiose narcissism is associated with taking and posting more selfies, experiencing more positive affect when taking selfies, and self-reported self-presentation motives. The Dark Triad traits resembled grandiose narcissism. Vulnerable narcissism was associated with negative affect when taking selfies. Self-esteem was unrelated to selfie-taking.
