Security and ethical issues in the virtual world of Second Life

In recent times, Virtual Worlds such as Second Life have generated substantial publicity due to the participation of Fortune 500 companies, and other public and private organisations. As practitioners continue to discuss how organisations could derive business value from Virtual Worlds, new security and ethical issues in Virtual Worlds have emerged to challenge Virtual World users and stakeholders. This paper discusses privacy, intellectual property and a host of other security and ethical issues in Virtual Worlds. It contributes to practice and research by (i) providing insight into emerging security and ethical issues in Virtual Worlds, (ii) analysing the implication of these issues, within and beyond Virtual Worlds, and (iii) raising awareness on security and ethics among Virtual World users and stakeholders.

Do female and male employees in Iran experience similar work-family interference, job and life satisfaction?

This study aims at examining gender differences in the experience of work–family interference and perceived job–life satisfaction in a group of Iranian employees. The participants in the study consist of 387 Iranian male and female employees from a variety of organizations. The results of t tests and multiple regression analysis using EQS 6.1 support the hypothesis that Iranian male and female employees experience similar interference in their work–family domains although they spend different numbers of hours in the workplace. The findings also show that whereas work-to-family interference has significant and negative effects on job–life satisfaction among male employees, for female employees, working hours and family-to-work interference had even more significant and negative effects on their job–ife satisfaction. Implications are discussed and recommendations made regarding future research and interventions in this area.

Evaluating quality of life in hip and knee replacement: psychometric properties of the World Health Organization Quality of Life short version instrument

Objective: To evaluate the psychometric properties of the World Health Organization Quality of Life short version instrument (WHOQOL-BREF), and to determine its responsiveness in assessing early outcome after total hip or knee replacement surgery.

Methods: At baseline (entry to an orthopedic waiting list), 279 participants completed the WHOQOL-BREF instrument, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Assessment of Quality of Life (AQOL) instrument, Kessler Psychological Distress (K10) scale, and the modified Health Assessment Questionnaire (MHAQ). A total of 74 patients completed reassessments 3 months after surgery.

Results: The WHOQOL-BREF demonstrated acceptable internal consistency for all domains (Cronbach's = 0.76-0.84) and moderate concurrent validity for the physical and psychological domains (r = 0.67 for physical versus AQOL; r = -0.71 for psychological versus K10). Minimal ceiling or floor effects were identified at baseline or 3 months, except for the social relationships domain. The disease-specific WOMAC subscales were most responsive to change (relative efficiency [RE] 0.66-1.00). Apart from social relationships, all WHOQOL-BREF scores improved significantly after surgery. The physical domain was more responsive than the AQOL (RE 0.50 versus 0.42) and was similar to the MHAQ (RE 0.55 for MHAQ). The responsiveness of the psychological domain was similar to that of the K10 scale (RE 0.11 versus 0.08).

Conclusion: The WHOQOL-BREF has good psychometric properties for use in persons with severe joint disease, and by providing complementary information, it offers clinicians and researchers an additional tool for comprehensively assessing quality of life in this patient group.

Symptoms, ill-health and quality of life of the members of a Porton Down veterans' support group

Background There has been a Human Volunteer Programme at the British chemical weapons research facility at Porton Down since the First World War, in which some of the participants were exposed to chemical warfare agents.

Aim To identify any striking specific morbidity patterns in members of the Porton Down Veterans Support Group (PDVSG).

Methods A self-completed postal questionnaire was prepared including health immediately after the visits to Porton Down, subsequent diagnoses and hospital admissions, symptoms in, and after, the first 5 years after the visits, fatigue symptoms and current quality of life, measured using the SF-36.

Results Responses were received from 289 of 436 (66%). Results reported here relate to 269 male respondents of mean age 66.8 years. Sixty-six per cent reported their first visit to Porton Down in the 1950s. The most common diagnoses or hospital admissions reported were diseases of the circulatory system. In the first 5 years after their visits the most common symptoms were headache, irritability or outbursts of anger and feeling un-refreshed after sleep. In the later period, most common symptoms were fatigue, feeling un-refreshed after sleep and sleeping difficulties. Sixty-five per cent met the definition for a case of ‘fatigue’. Current quality of life dimensions were consistently lower than age-specific estimates from general population samples.

Conclusions Members of the PDVSG responding to this survey reported poorer quality of life than the general population. Despite there being no clear pattern of specific morbidities, we cannot rule out ill-health being potentially associated with past experience at Porton Down

Enriching student experience and inter-professional learning of inclusive design with Second Life

This position paper reflects rapid advances in immersive 2D and 3D eLearning technologies and the expanding pool of ideas and applications in higher education across two professions. Inspiration has been drawn from examples in design learning, and various multidisciplinary collaborative projects through developmental research in Multi-User Virtual Environments (MUVEs). Linden Lab's Second Life (SL) is the most mature and popular of the ‘persistent’ virtual worlds. The study described in this paper aims to increase the authenticity of student learning through a range of SL simulated ‘life experiences’ relating to accessibility and mobility in the built environment. Significantly, the successes of such initiatives lie in several elements: teaching champions with vision and courage; detailed scripting of precise role-play encounters for first-time users to provide supportive ‘blended learning’ contexts; careful and vigilant strategic management of facilities and resources, and a robust design program. This paper focuses on the crucial alignment of these elements to the specific challenges of designing and navigating conception and development processes, to enable the execution and delivery of a tightly defined script for meaningful and memorable learning outcomes. This innovative pedagogical approach lacks time-tested outcomes, but is recognised equally as opportunity and challenge; risk and reward.

Striving for educational equity and ‘world-class quality’ schools in Mauritius in global times

Concerns that the education system in Mauritius has not been adequately preparing students for work and life, and unsatisfactory academic achievement in schools, have fuelled the government’s drive to improve the quality of schools. These concerns exist within education structures that systematically segregate students into ‘star’ schools and less desirable schools that curtail the education experience of the majority of Mauritian children. Within this context, Mauritian education authorities have attempted various educational reforms aiming at ‘World Class Quality Education’ so as to contribute to an efficient and dynamic workforce and to meet the needs of an increasingly competitive, knowledge-based and globalised economy. Reflecting the Mauritian government’s ‘quality’ agenda and its focus on the work of school leaders, this article reports the findings of research exploring Mauritian principals’ views about the usefulness or otherwise of Total Quality Management (TQM) principles in raising educational standards. It focuses specifically on whether and how principals are addressing the mounting challenges brought about by globalisation. The findings indicate that, despite the government’s efforts at reforms, the education system detracts from ambitions to adequately prepare all Mauritian children for work and life in a globalised and networked world. The article argues that school leaders need to take proactive responsibility for ensuring that all Mauritian children have access to an education system that cultivates their participation as active citizens of the global community.
