Finding appropriate tools and platforms to maintain and manage their activities is a major challenge for communities of practice (CoPs). We reviewed in this research several platforms used by CoPs from several backgrounds (IT, education, social activities, etc.) in order to identify common tools that might help in proposing guidelines for dedicated CoPs' platforms. We classified the reviewed platforms into four main categories: basic tools (forums), simple platforms (content management systems), community-oriented platforms (portals) and proprietary platforms (Youmedia, iwlearn). Indeed, we identified four main limitations of the reviewed platforms namely: single authentication to the platform, common repository of resources and global search, notification and performing activities. Consequently, we discussed and justified adopting a pivot technology for implementing CoPs' platform (widget technology). Additionally, we justified the necessity in providing interoperability of embedded tools for performing activities. Finally, a proposed logical structure of the dedicated platform for CoPs was discussed then justified. © 2017 Inderscience Enterprises Ltd.

Requirements elicitation is a key and critical activity for software/system development success. Several methods and techniques have been developed and used for requirements elicitation. Prior research referred to many problems and shortfalls with existing group-based methods (e.g., brainstorming, focus groups, and joint application development [JAD]). This paper provides a new approach for requirements elicitation using a novel method called discount focus subgroups (DFSG). The current paper demonstrates that DFSG is an alternative effective technique to improve requirements elicitation activity by addressing pitfalls and problems with existing group-based methods. The method is effective in several situations such as when the development team aims to minimize the costs of system development, large numbers of stakeholders need to be involved in large projects like enterprise systems (ERP), the system is novel and where no similar systems have been developed before.

Positive associations between human intelligence and brain size have been suspected for more than 150 years. Nowadays, modern non-invasive measures of in vivo brain volume (Magnetic Resonance Imaging) make it possible to reliably assess associations with IQ. By means of a systematic review of published studies and unpublished results obtained by personal communications with researchers, we identified 88 studies examining effect sizes of 148 healthy and clinical mixed-sex samples (>8000 individuals). Our results showed significant positive associations of brain volume and IQ (r=.24, R2=.06) that generalize over age (children vs. adults), IQ domain (full-scale, performance, and verbal IQ), and sex. Application of a number of methods for detection of publication bias indicates that strong and positive correlation coefficients have been reported frequently in the literature whilst small and non-significant associations appear to have been often omitted from reports. We show that the strength of the positive association of brain volume and IQ has been overestimated in the literature, but remains robust even when accounting for different types of dissemination bias, although reported effects have been declining over time. While it is tempting to interpret this association in the context of human cognitive evolution and species differences in brain size and cognitive ability, we show that it is not warranted to interpret brain size as an isomorphic proxy of human intelligence differences. © 2015 Elsevier Ltd.

This paper aims to achieve two fundamental objectives. First, we examine whether the electric consumption of the GCC countries exhibit any form of non-linearity that is of economic interest. In this context, we use the BDS test in order to determine the absence or presence of linear or non-linear dependence. The test results indicate that there is a substantial non-linear dependence in all the series of the countries in the region. In the second objective, we investigate the asymmetric properties of the electric consumption of these countries. In particular, we explore two types of asymmetry: deepness and steepness. The test results indicate that there is a strong corroborative evidence of asymmetric deepness and steepness relative to trend in these countries’ electric consumption variable. © 2015, Econjournals.

This article studies the effect of electronic commerce on perceptions of export barriers in a developing country. Five categories of export barriers were evaluated in this study, including organizational barriers, operational barriers, psychological barriers, product and market barriers, and psychic distance barriers. Findings indicate that perceptions of organizational, operational, psychological, and product and market barriers did not differ significantly based on whether the exporters used electronic commerce or not. However, perceptions of psychic distance barriers were significantly higher in companies with Web sites. Psychic distance barriers included ignorance of the need to conduct research in foreign markets and difficulties with foreign representatives. Results show that the pattern of perception of barriers to export depended upon the kinds of barriers. The study contributes to an improved understanding of the use of electronic commerce for exporting small and medium enterprises in developing countries. © Taylor & Francis Group, LLC.

This paper presents case study findings of exploratory research on the growth of Event Tourism in Dubai, UAE. Dubai targeted tourism as a growth industry in the 1990s and is now emerging as a world-class event destination. The research takes an epistemological approach in exploring theoretical knowledge of tourism events along with practical knowledge of their development and delivery. Utilizing a typology of Dubai events and a narrative of their growth, a conceptual framework is developed to guide related research into the behaviour of event tourists. Findings show Dubai has applied a diverse strategic approach in developing a strong brand image and events have significantly contributed to this as a brand extension, a key brand element, and as a co-branding partner. © 2016 Informa UK Limited, trading as Taylor & Francis Group

The emergence of social media has created a new medium for administering surveys for tourism research. While social media has great potential for tourism researchers, several aspects need to be considered. In the case of backpackers, a traditionally "difficult-to-sample" group, destination-based surveys, email surveys, survey links posted in online forums, and social media sites such as Facebook have all been used to administer surveys. The purpose of this paper is to present the case for a mixed-mode dual-frame sampling procedure as an optimum for targeting backpackers. The sampling procedure discussed in this paper included self-administered surveys through backpacker-specific groups on and self-administered surveys at backpacker hostels in Cairns, Australia. This paper argues that for this particular group, combining offline and online sampling modes allows the research to minimize errors while maximizing the diversity. Additionally, this paper provides some insights and recommendations into administering surveys through Facebook for tourism researchers. © 2013 Copyright Taylor and Francis Group, LLC.

This paper examines the principles and practices of Islamic hospitality, outlining the diverse ways in which Islam intersects with 'hospitality' and the 'hospitality industry'. The intangible elements of Islamic hospitality are initially discussed, particularly the importance of the host-guest relationship and differing cultural interpretations. The discussion then evaluates the tangible aspects of Islamic hospitality through identifying trends, developments and challenges within the hotel sector, the food production and service sector, and the festivals and events sector. The work adopts a global perspective, examining Islamic hospitality with reference to both OIC (Organization of Islamic Cooperation) countries and non-OIC countries. The paper also considers new sector opportunities and acknowledges the social difficulties associated with the development of Islamic hospitality within the Western world, notably Islamophobia. Finally, the paper indicates ways forward for future research. © 2013 Elsevier Ltd.

Cost Effectiveness and Resource Allocation | Year: 2016

Background: The Palestinian government has been under increasing pressure to improve provision of health services while seeking to effectively employ its scare resources. Governmental hospitals remain the leading costly units as they consume about 60 % of governmental health budget. A clearer understanding of the technical efficiency of hospitals is crucial to shape future health policy reforms. In this paper, we used stochastic frontier analysis to measure technical efficiency of governmental hospitals, the first of its kind nationally. Methods: We estimated maximum likelihood random-effects and time-invariant efficiency model developed by Battese and Coelli, 1988. Number of beds, number of doctors, number of nurses, and number of non-medical staff, were used as the input variables, and sum of number of treated inpatients and outpatients was used as output variable. Our dataset includes balanced panel data of 22 governmental hospitals over a period of 6 years. Cobb-Douglas function, translog function, and multi-output distance function were estimated using STATA 12. Results: The average technical efficiency of hospitals was approximately 55 %, and ranged from 28 to 91 %. Doctors and nurses appear to be the most important factors in hospital production, as 1 % increase in number of doctors, results in an increase in the production of the hospital of 0.33 and 0.51 %, respectively. If hospitals increase all inputs by 1 %, their production would increase by 0.74 %. Hospitals production process has a decrease return to scale. Conclusion: Despite continued investment in governmental hospitals, they remained relatively inefficient. Using the existing amount of resources, the amount of delivered outputs can be improved 45 % which provides insight into mismanagement of available resources. To address hospital inefficiency, it is important to increase the numbers of doctors and nurses. The number of non-medical staff should be reduced. Offering the option of early retirement, limit hiring, and transfer to primary health care centers are possible options. It is crucial to maintain a rich clinical skill-mix when implementing such measures. Adopting interventions to improve the quality of management in hospitals will improve efficiency. International benchmarking provides more insights on sources of hospital inefficiency. © 2016 Hamidi.
