    The purpose of this study was to evaluate the factor structure of the Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA). The LSAS-CA was administered to 225 children and adolescents as a component of various clinical studies. In addition, other measures of psychopathology and impairment were administered to a subgroup of the sample. Confirmatory factor analyses of the social interaction and performance subscales for the anxiety and avoidance ratings yielded poor fit indices. Exploratory factor analysis supported a two-factor solution with a higher order factor for the LSAS-CA anxiety and avoidance ratings. Based on item content, factors were named Social and School Performance. The internal consistency of the factors was high and the convergent and divergent validity was supported vis-à-vis correlations with measures of depression and social anxiety, and clinician ratings of impairment and functioning. Findings suggest that the anxiety and avoidance ratings are best explained by a two-factor solution that measures social anxiety and avoidance in social and school performance interactions. This factor structure appears to be a reliable and valid framework for assessing childhood social phobia

    Objective: To examine the psychometric properties of a newly developed clinician rating scale, the Liebowitz Social Anxiety Scale for Children and Adolescents (LSAS-CA), Method: A total of 154 children and adolescents participated in an assessment consisting of a diagnostic interview, the LSAS-CA, and other measures of psychopathology and impairment. Sixty-one of these children also participated in a second LSAS-CA administration, by a different rater blind to diagnosis, within 7 days of the initial assessment. Results: High internal consistency (α = .90-.97 for full sample and .S3-.95 for social phobia group) and test-retest reliability (intraclass correlation coefficient = 0.89-0.94) were obtained for LSAS-CA total and subscale scores. LSAS-CA scores had stronger associations with measures of social anxiety and general impairment than with a measure of depression. Subjects with social anxiety disorder had significantly higher LSAS-CA scores than subjects with other anxiety disorders and healthy controls. A LSAS-CA cutoff score of 22.5 represented the best balance of sensitivity and specificity when distinguishing between individuals with social phobia and normal controls, whereas a cutoff of 29.5 was optimal for distinguishing social phobia from other anxiety disorders. Conclusion: Initial findings suggest that the LSAS-CA is a reliable and valid instrument for the assessment of social anxiety disorder

    Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers

    No full text
    In the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)

    Piracy on the High C's: Music Downloading, Sales Displacement, and Social Welfare in a Sample of College Students

    No full text
    Recording industry revenue has fallen sharply in the last three years, and some -- but not all -- observers attribute this to file sharing. We collect new data on albums obtained via purchase and downloading, as well as the consumers' valuations of these albums, among a sample of US college students in 2003. We provide new estimates of sales displacement induced by downloading using both OLS and an instrumental variables approach using access to broadband as a source of exogenous variation in downloading. Each album download reduces purchases by about 0.2 in our sample, although possibly much more. Our valuation data allow us to measure the effects of downloading on welfare as well as expenditure in a subsample of Penn undergraduates, and we find that downloading reduces their per capita expenditure (on hit albums released 1999-2003) from 126to126 to 100 but raises per capita consumer welfare by $70.

    Moral erosion: how can medical professionals safeguard against the slippery slope?

    No full text
    The extensive participation of German physicians in the atrocities of the Holocaust raises many questions concerning the potential for moral erosion in medicine. What circumstances and methods of rationalisation allowed doctors to turn from healers into accomplices of genocide? Are physicians still vulnerable to corruption of their guiding principles and, if so, what can be done to prevent this process from occurring? With these thoughts in mind, the author reflects on his experiences participating in the Fellowships at Auschwitz for the Study of Professional Ethics program and offers a medical student's perspective on the ethical issues encountered in clinical training and the practice of medicine

    The spotlight effect and the illusion of transparency in social anxiety

    [Clark, D. M., & Wells, A. (1995). A cognitive model of social phobia. In: R. G. Heimberg, M. R. Liebowitz, D. A. Hope, & F. R. Schneier (Eds.), Social phobia: diagnosis, assessment, and treatment (pp. 69–93). New York: Guildford Press] cognitive model of social phobia suggests that both public and private sources of information contribute to the construction of the self as a social object, which is thought to maintain the disorder. This study used two concepts developed in social psychology that might help to explain the processes that contribute to the development of this constructed self. These two concepts are the spotlight effect [Gilovich, T., Medvec, V. H., & Savitsky, K. (2000). The spotlight effect in social judgment: an egocentric bias in estimates of the salience of one’s own actions and appearance. Journal of Personality and Social Psychology, 78(2), 211–222] and the illusion of transparency [Gilovich, T., Medvec, V. H., & Savitsky, K. (1998). The Illusion of transparency: biased assessments of others’ ability to read one’s own emotional states. Journal of personality and social psychology, 75(2), 332–346]. Participants performed a memory task under either a low or a high social-evaluative condition. In the high social-evaluative condition, participants reported higher levels of the spotlight effect and more negative evaluation of task performance, compared to participants in the low social-evaluative condition. There were no differences between the two conditions in levels of the illusion of transparency. Surprisingly, however, in the low socialevaluative condition, participants reported higher levels of the illusion of transparency than the spotlight effect, whereas, in the high social-evaluative condition, they reported the opposite. Results suggest that the spotlight effect may be specific to social-evaluative concerns, whereas, the illusion of transparency may represent more general features of social anxiety concerns. Implications of the results for Clark and Wells’ cognitive model of social phobia model are discussed

    Co-Designing the Driver's Seat: A call for an "Open" Approach to Drawing Production in Spatial Design Practice

    The question of what the architect is actually doing … raises questions about authorship. Is the architect a creative author with the will to produce a specific work, or do the conditions imposed on him inevitably result in something interchangeable, something that could as easily have been produced by someone one else? (Reidijk, 2010, p20) This inherent contravention of authorship, summarised in the prologue of Reidijk’s collection of writings in Architecture as Craft, brings to light a crucial aspect of the built environment’s process of production; rarely is a building or a space solely brought together through an individual’s vision and efforts. As a rule, the built spaces occupied by society are the result of multiple forms of agency and ownership working together at different levels. While this co-productive nature of built space is well established through Open Building discourse, the nature of the design communication artefacts to which are trusted to carry the idea to be understood through remain largely ‘closed’ within the disciplinary boundaries of the designer and select group of building professionals. Nowhere is this closure more evidently seen than in technical output produced and commoditised by large scale design practices, such as urban and city design in South Africa. The author firmly stands by the belief that in order to allow for the true co-production of the South Africa built environment to take place equitably and efficiently, spatial design practitioners need to develop more ‘open’ approaches to the practice in the built environment – in particular to allow the design communication artefacts of their discipline to be co-owned and co-produced in the face of a rapidly urbanising world. In 2015 the author of this paper assisted in the running of UJ_UNIT2; a design-led architectural research unit housed in the master’s programme at the University Of Johannesburg (UJ). The research unit embarked on an exploration of new forms of design and building exposing the nature of agency through the levels that make up the South African built environment. This experience, combined with the author’s personal work in providing socio-technical support to the grass-roots international organisation Slum/Shack Dwellers International, provide the experiential reference to support the above stated belief. This paper will examine two projects conducted through the author’s own teaching and design practice that attempted to change the manner in which designer’s see and control design communication artefacts. A summary of these experiences will then be outlined through a call for design practitioners to develop their own means of sharing control not only in the spatial drawing artefact, but in the design itself. This is done with the hope of supporting a growing national movement that seeks to responsibly relinquish power through design in the aim of achieving social and spatial justice in South Africa
