For better characterizing the heat distribution of data centers, Multi-zone Model are considered in this paper, modularizing the cold and hot aisle space of a data center into several regular modules. Upon studying the thermal transmission between every two modules, the heat distribution of all cold and hot aisles in a data center was figured out. Firstly, while considering the thermal transmission, Multi-zone Heat-mass Balanced Model, a model improved from a traditional one, was established. Three modules, which are wall flow module, thermal plume module and thermal transmission module, consists the model. The model characterizes the thermal transmission in both vertical and horizontal direction by integrating the heat conduction of walls, wall convective heat exchange and convective heat exchange among sub-regions. Then, Multi-zone Heat Distribution Model were built by combining the established modules, wall flow module, thermal plume module and thermal transmission module, with Heatmass Balanced Model. The new model makes the contribution to a detailed characterization of cold-and-hot-aislespace heat distribution in a data center. Finally, the heat distribution model, combined with data in a case, was numerically simulated. Comparing the simulation results with data in the case, conclusion can be made that the Multi-zone Heat Distribution Model enjoys well consistency and robustness. © 2013 Maxwell Scientific Organization.

The article traces the history of the Poly Implant Prosthesis (PIP) scandal from an ethical perspective and explores the underpinning moral dilemmas inherent in the act of 'whistleblowing.' It goes on to consider the consequential stakeholder and broader societal reaction to whistleblowing which is discussed through deontological and teleological perspectives of ethically driven motives to act. It draws on the duty of care responsibility of healthcare professionals and the dilemma of personal consequence by the act of whistleblowing, whereby the objective of that act is the maintenance or improvement of patient standards and care. It argues that a cultural shift in organisational behaviour is urgently required to abrogate the needs for whistleblowing by means of internal systems and processes. Whistleblowing would thus become a supererogatory act of moral courage rather than carrying negative consequences in the interests of short-term saving face.

The Implementation of Enterprise Resource Planning (ERP) systems require huge investments while ineffective implementations of such projects are commonly observed. A considerable number of these projects have been reported to fail or take longer than it was initially planned, while previous studies show that the aim of rapid implementation of such projects has not been successful and the failure of the fundamental goals in these projects have imposed huge amounts of costs on investors. Some of the major consequences are the reduction in demand for such products and the introduction of further skepticism to the managers and investors of ERP systems. In this regard, it is important to understand the factors determining success or failure of ERP implementation. The aim of this paper is to study the critical success factors (CSFs) in implementing ERP systems and to develop a conceptual model which can serve as a basis for ERP project managers. These critical success factors that are called "core critical success factors" are extracted from 62 published papers using the content analysis and the entropy method. The proposed conceptual model has been verifed in the context of fve multinational companies.

The 2008-2009 global financial crisis and its subsequent ramifications on capital markets have led to an increasing attention on the importance of cognitive and behavioral issues in finance. The purpose of this study is to determine the ranking of the industry alternatives for portfolio investments based on individual investors' perceptions. Accordingly, a hybrid analytic multi-criteria decision model (MCDM)-based on the Fuzzy Analytic Hierarchy Process (FAHP) and the Fuzzy Technique for the Order of Preference by Similarity to Ideal Solution (FTOPSIS) methods along with sensitivity analysis-is developed to identify and rank-order the best performing industry options. The proposed model is applied to Borsa Istanbul Stock Exchange 100 Index (BIST 100) in Turkey. The results indicate that (i) the investors' perceptions on market conditions and global financial situation influence their industry selection on company stocks; (ii) the investors' perceptions on portfolio investments rely heavily on performance and risk levels of individual asset/stocks, and (iii) traded stocks of financial industry (along with its sub-industries) have greater performance expectations than those of the ones in other industries such as technology, services and tourism. © 2016 Elsevier B.V.

Background.Different studies have analysed a wide range of use cases and scenarios for using IT-based services in homecare settings for elderly people. In most instances, the impact of such services has been studied using a one-dimensional approach, either focusing on the benefits for the patient or health service provider. Purpose.The objective of this contribution is to explore a model for identifying and understanding outcomes of IT-based homecare services from a multi-actor perspective. Methods.In order to better understand the state of the art in homecare informatics, we conducted a literature review. We use experiences from previous research in the area of informatics to develop the proposed model. Results.The proposed model consists of four core activities 'identify involved actors', 'understand consequences', 'clarify contingencies', 'take corrective actions', and one additional activity 'brainstorming IT use'. Conclusion.The primary goal of innovating organisations, processes and services in homecare informatics today, is to offer continued care, better decision support both to practitioners and patients, as well as effective distribution of resources. A multi-actor analysis perspective is needed to understand utility determination for the involved stakeholders. © 2011 Informa UK, Ltd.

This paper investigates the nexus between economic growth, export and public debt in Malaysia. The analysis was conducted using the VECM framework and the Granger Causality test over the period of 1970–2013 in order to explore the existence of causality relationship between these variables. The findings from the analysis show the existence of long run bi-directional relationship between public debt and exports of Malaysia. The causality tests statistics do not support the existence of short run causality relationship from public debt to GDP, or vice versa. The test results also fail to support the existence of short run causal relationship between exports and public debt. However, this study found evidence to support the existence of uni-directional short run causal relationship from exports to public debt in Malaysia. In conclusion, the government debt may not influence Malaysia’s economic growth in the short run, but it could affect the exports in the long run and subsequently the sustainability of the economy. © 2015 American Scientific Publishers.

The review highlights the main features of internal audit by focus on distribution of medicinal products. Recent data suggest internal audit as an antidote to effects of economic recession. The present review reveals internal audit as a tool for competitiveness through implementation of good practices. The purpose of the review is to describe the advantages of internal audit in new institutional frame. The object of analysis is the distribution practice, and more concrete, the wholesale distributors. The analysis was perform by factor analysis and done in response to the tendency for outsource of distribution activities and practical interest in the use of internal audit by implementation of requirements and recommendations for good practices. The results showed that the internal audit in pharmaceutical industry is determinate by two factors: regulatory requirements and complexity of supply chain. The external and the internal environment define five features of internal audit in pharmaceutical industry.

This study aims to examine the moderating effect of technostress inhibitors on the relationship between technostress creators and organisational commitment among academic librarians in the Malaysian public universities. It considers how literacy facilitation, technical support, and involvement facilitation influence the strength of the relationship between technostress creators and organisational commitment. Multiple regression analysis and hierarchical multiple regression analysis were utilised to test the relationship and the moderating effect among the variables. The findings revealed that collectively, technostress creators significantly explained 13.1 percent of the variance in organisational commitment. Techno-overload and techno-uncertainty were found to have significant positive relationship with organisational commitment. As for the moderating effect, both literacy facilitation and involvement facilitation did not act as moderator in the relationship between technostress creators and organisational commitment. Nevertheless, technical support was found to moderate the relationship between techno-overload and organisational commitment. All the technostress inhibitors were, however, found to be significant predictors for organisational commitment. This study demonstrates that a certain amount of stress is essential in enhancing employee's commitment towards organisation. Moreover, it reveals that the existence of literacy facilitation, technical support, and involvement facilitation is crucial in boosting organisational commitment of academic librarians in the Malaysian public universities. © 2014 Penerbit UTM Press.
