    Get PDF
    During the last decade, the integration of management systems (this includes any management system that is used to achieve the goals of an organisation example PASCAL, ISO standards and enterprise resource planning), has become an increasingly important strategy adopted by organisations, as it represents an alternative to operating with multiple management systems in parallel (Abad, Cabrera & Medina, 2014:860). Despite the established need for the integration of management systems, research on how to carry out integration has yet to be developed fully and an elaborated methodology of integration needs full realisation (Bernardo, CasadesĂșs, Karapetrovic & Heras, 2012; Rocha, Searcy, Karapetrovic, 2007; Wilkinson & Dale, 1999a; Zeng, Shi & Lou, 2007). The aim of the current study was to develop a framework for organisations that could be used for the integration of management systems in a structured manner. This study was undertaken by exploring the views and opinions of senior management through fourteen face-to-face semi-structured interviews. Thereafter, an online survey collected 220 responses from four South African multinational organisations involved with management system development and implementation. The research instrument used a seven-point Likert-type scale for the respondents to rate each question. The data was analysed statistically primarily using factor analysis to confirm the significant factors and then structural equation modelling to test the relationships between the factors, which ultimately confirmed the developed framework. The beneficiaries of this research are primarily organisations that have three or more management systems in an organisation. The framework will also be valuable to management in industry and policymakers since it addresses key integration issues, such as employee performance, organisational culture, employee motivation and policy as factors when considering integration of management systems.Kule minyaka ilishumi idluleyo amaqumrhu aye aphuhlisa ngamandla icebo lobulumko lokuhlanganiswa kweenkqubo zolawulo (kuquka nayiphi na inkqubo yolawulo esetyenziselwa ukufezekisa iinjongo zequmrhu, iinkqubo ezifana nePASCAL, ISO, ne standards and enterprise resource planning). Oku kumele indlela eyenye yokusebenzisa ngaxeshanye iinkqubo zolawulo ezininzi (Abad, Cabrera & Medina, 2014:860). Ngaphandle kokuba siqondakala kakuhle isidingo sokuhlanganisa iinkqubo zolawulo, alukaphuhliswa kakuhle uphando lokuqhuba oko kuhlanganisa (Bernardo, CasadesĂșs, Karapetrovic & Heras, 2012; Rocha, Searcy & Karapetrovic, 2007; Wilkinson & Dale, 1999a; Zeng, Shi & Lou, 2007). Injongo yolu phando kukuphuhlisa isakhelo esinokusetyenziswa ngamaqumrhu ekuhlanganiseni iinkqubo zolawulo ngendlela efanelekileyo. Esi sifundo saqhutywa ngokuphengulula izimvo neengcinga zabaphathi abakwizinga elingentla ngokuqhuba udliwano ndlebe nabaphathi abali-14 nganye nganye. Emva koko kwenziwa intlolomvo kubantu abangama-220 abasebenza kumaqumrhu amane aseMzantsi Afrika, maqumrhu lawo asebenza ngophuhliso nokusetyenziswa kweenkqubo zolawulo. Isixhobo sophando esisetyenzisiweyo sisikali esineencam esisixhenxe esiludidi lweLikert, apho abathathi nxaxheba bebeka esikalini umbuzo ngamnye abawunikiweyo. Iinkcukacha zolwazi zahlalutywa ngobuchule bezobalo, kuqukaniswa iimpendulo ezenza udidi olunye, emva koko kwasetyenziswa indlela yokuhlalutya apho kuphononongwa ukwalamana ngoonobangela neziphumo zemiba ethile, okuthe ekugqibeleni kwaveliswa isakhelo. Abancedakeleyo lolu phando ngamaqumrhu asebenzisa iinkqubo zolawulo ezintathu nangaphezulu. Isakhelo esiphuhlisiweyo siya kuba luncedo kakhulu kubalawuli nabaqulunqi bomgaqo nkqubo, kuba sijolise kwimibandela yokuhlanganisa, efana nendlela abasebenza ngayo abaqeshwa, inkcubeko yequmrhu, ukukhuthazwa kwabasebenzi nemiba emalunga nomgaqo nkqubo oqwalaselwa xa kuhlanganiswa iinkqubo zolawuloKule minyaka eyishumi edlule, ukuhlanganiswa kwezinhlelo zokuphatha (kufaka kukho noma yiluphi uhlelo lokuphatha olusetshenziselwa ukufeza izinhloso zenhlangano, njengePASCAL, amaqophelo e-ISO kanye nokuhlelwa kwezinsiza zebhizinisi), sekuyicebo elibaluleke kakhulu elamukelwa yizinhlangano, njengoba kumele enye indlela yokusebenza nezinhlelo eziningi zokuphatha ngokuhambisanayo (Abad, Cabrera & Medina, 2014: 860). Yize sekubonakale isidingo sokuhlanganiswa kwezinhlelo zokuphatha, ucwaningo lokuthi kuzohlanganiswa kanjani kusamele luthuthukiswe ngokuphelele kanti nendlela ecacile yokuhlanganiswa kumele ifezeke ngokugcwele (Bernardo, CasadesĂșs, Karapetrovic & Heras, 2012; Rocha, Searcy & Karapetrovic, 2007; Wilkinson & Dale, 1999a; Zeng, Shi & Lou, 2007). Inhloso yocwaningo lwamanje bekungukuthuthukisa uhlaka lwezinhlangano olungasetshenziselwa ukuhlanganiswa kwezinhlelo zokuphatha ngendlela ehlelekile. Lolu cwaningo lwenziwe ngokuhlola imibono nemicabango yabaphathi abaphezulu ngokuba nezingxoxo eziyi-14 ezingahlelekile ngokuphelele ezibe khona kuxoxwa ubuso nobuso. Ngemuva kwalokho, ucwaningo olwenziwa ngokuqoqa imininingwane ngobuchwepheshe bekhompuyutha lwaqoqa izimpendulo ezingama-220 ezinhlanganweni ezine zaseNingizimu Afrika ezihlanganise amazwe ahlukene nezibandakanyeka ekusungulweni nasekuqaliseni ukusebenza kohlelo lokuphatha. Kusetshenziswe indlela yokucwaninga yesikali sohlobo lwe-Likert samaphoyinti ayisikhombisa abaphendulayo abakala ngaso umbuzo ngamunye. Imininingwane ihlaziyiwe ngokwezibalo kusetshenziswa ukuhlaziywa kwezinto ngokuqavile ukuqinisekisa izici ezibalulekile bese kulandelwa indlela yokulinganisa ukwakheka ukuhlola ubudlelwano phakathi kwezici, okugcina kuqinisekisa uhlaka olusunguliwe. Abahlomuli balolu cwaningo ngokuqavile yizinhlangano ezinezinhlelo ezintathu noma ngaphezulu zokuphatha enhlanganweni. Uhlaka luzoba wusizo nakubaphathi embonini nakubenzi bezinqubomgomo, njengoba lubheka izingqinamba ezibalulekile zokuhlanganiswa, njengokusebenza kahle kwabasebenzi, isiko lenhlangano, ukukhuthazwa kwabasebenzi kanye nenqubomgomo njengezinto ezibhekwayo uma kucatshangwa ngokuhlanganiswa kwezinhlelo zokuphatha.SBLD.B.L

    Malaysian bilateral trade relations and economic growth

    Get PDF
    This paper examines the structure and trends of Malaysian bilateral exports and imports and then investigates whether these bilateral exports and imports have caused Malaysian economic growth. Although the structure of Malaysia’s trade has changed quite significantly over the last three decades, the direction of Malaysia’s trade remains generally the same. Broadly, ASEAN, the EU, East Asia, the US and Japan continue to be the Malaysia’s major trading partners. The Granger causality tests have shown that it is the bilateral imports that have caused economic growth in Malaysia rather than the bilateral exports

    Exchange rate misalignments in ASEAN-5 countries

    The purpose of this paper is to estimate the exchange rate misalignments for Indonesia, Malaysia, Philippines, Singapore and Thailand before the currency crisis. By employing the sticky-price monetary exchange rate model in the environment of vector error-correction, the results indicate that the Indonesia rupiah, Malaysian ringgit, Philippines peso and Singapore dollar were overvalued before the currency crisis while Thai baht was undervalued on the eve of the crisis. However, they suffered modest misalignment. Therefore, little evidence of exchange misalignment is found to exist in 1997:2. In particular, Indonesia rupiah, Malaysia ringgit, Philippines peso and Singapore dollar were only overvalued about 1 to 4 percent against US dollar while the Thai baht was only 2 percent undervalued against US dollar

    The research first aims to investigate the effects of all influencing factors on household energy consumption and to evaluate their complex relationships under different situation. Hybrid modeling combing physics-based modeling and data-driven modeling is the state-of-the-art approach to be considered for energy forecast, while factor analysis has the potential for sorting the weight of factors. Discussion on the final results imply cognitive changes for consumers where the visualization of energy efficiency optimization can be easily captured so that environmental sustainability will be closer than ever.挗äčć·žćž‚立性

    Proceedings of the inaugural construction management and economics ‘Past, Present and Future’ conference CME25, 16-18 July 2007, University of Reading, UK

    Get PDF
    This conference was an unusual and interesting event. Celebrating 25 years of Construction Management and Economics provides us with an opportunity to reflect on the research that has been reported over the years, to consider where we are now, and to think about the future of academic research in this area. Hence the sub-title of this conference: “past, present and future”. Looking through these papers, some things are clear. First, the range of topics considered interesting has expanded hugely since the journal was first published. Second, the research methods are also more diverse. Third, the involvement of wider groups of stakeholder is evident. There is a danger that this might lead to dilution of the field. But my instinct has always been to argue against the notion that Construction Management and Economics represents a discipline, as such. Granted, there are plenty of university departments around the world that would justify the idea of a discipline. But the vast majority of academic departments who contribute to the life of this journal carry different names to this. Indeed, the range and breadth of methodological approaches to the research reported in Construction Management and Economics indicates that there are several different academic disciplines being brought to bear on the construction sector. Some papers are based on economics, some on psychology and others on operational research, sociology, law, statistics, information technology, and so on. This is why I maintain that construction management is not an academic discipline, but a field of study to which a range of academic disciplines are applied. This may be why it is so interesting to be involved in this journal. The problems to which the papers are applied develop and grow. But the broad topics of the earliest papers in the journal are still relevant today. What has changed a lot is our interpretation of the problems that confront the construction sector all over the world, and the methodological approaches to resolving them. There is a constant difficulty in dealing with topics as inherently practical as these. While the demands of the academic world are driven by the need for the rigorous application of sound methods, the demands of the practical world are quite different. It can be difficult to meet the needs of both sets of stakeholders at the same time. However, increasing numbers of postgraduate courses in our area result in larger numbers of practitioners with a deeper appreciation of what research is all about, and how to interpret and apply the lessons from research. It also seems that there are contributions coming not just from construction-related university departments, but also from departments with identifiable methodological traditions of their own. I like to think that our authors can publish in journals beyond the construction-related areas, to disseminate their theoretical insights into other disciplines, and to contribute to the strength of this journal by citing our articles in more mono-disciplinary journals. This would contribute to the future of the journal in a very strong and developmental way. The greatest danger we face is in excessive self-citation, i.e. referring only to sources within the CM&E literature or, worse, referring only to other articles in the same journal. The only way to ensure a strong and influential position for journals and university departments like ours is to be sure that our work is informing other academic disciplines. This is what I would see as the future, our logical next step. If, as a community of researchers, we are not producing papers that challenge and inform the fundamentals of research methods and analytical processes, then no matter how practically relevant our output is to the industry, it will remain derivative and secondary, based on the methodological insights of others. The balancing act between methodological rigour and practical relevance is a difficult one, but not, of course, a balance that has to be struck in every single paper

    Managing operational risk among SMEs: the Malaysian perspective

    Get PDF
    Despite being one of the integral components in fostering Malaysia’s economic growth, small and medium-sized enterprises (SMEs) have failed to attain their full potential due to various challenges. Based on the SMEs Masterplan 2012-2020, the Malaysian government has outlined six key challenges that could impede company performance excellence: innovation and technology adoption, infrastructure, access to financing, legal and regulatory environment, market access and human capital development. These challenges might lead to operational risks, which would likely lower the SMEs performance. The objective of this study is to examine the relationship between operational risk, risk mitigation strategy, and company performance. Specifically, this study focuses on Malaysia’s SMEs manufacturing industry by suggesting agility as part of a mitigation strategy towards enhancing their performance. Although the government has spent billions of Malaysian Ringgit, the impact on SMEs’ performance is still unimpressive, a situation prompting this study to be conducted. A total of 152 companies from the SMEs manufacturing industry in Peninsular Malaysia participated in this study. The data was collected through the survey method. The relationships between the variables were tested using Partial Least Square-Structural Equation Modelling (PLS-SEM) software. Statistical results reveal that a company performance can be significantly affected by innovation and technology adoption risk, along with legal and regulatory environment risk. Furthermore, agility is found to have a moderating effect on the relationship between innovation and technology adoption risk, infrastructure risk, and legal and regulatory environment risk. Overall, the research findings indicate that this analytical model provides a good understanding of the factors influencing the company performance and risk management in Malaysia’s SMEs manufacturing industry

    Knowledge and Management Models for Sustainable Growth

    In the last years sustainability has become a topic of global concern and a key issue in the strategic agenda of both business organizations and public authorities and organisations. Significant changes in business landscape, the emergence of new technology, including social media, the pressure of new social concerns, have called into question established conceptualizations of competitiveness, wealth creation and growth. New and unaddressed set of issues regarding how private and public organisations manage and invest their resources to create sustainable value have brought to light. In particular the increasing focus on environmental and social themes has suggested new dimensions to be taken into account in the value creation dynamics, both at organisations and communities level. For companies the need of integrating corporate social and environmental responsibility issues into strategy and daily business operations, pose profound challenges, which, in turn, involve numerous processes and complex decisions influenced by many stakeholders. Facing these challenges calls for the creation, use and exploitation of new knowledge as well as the development of proper management models, approaches and tools aimed to contribute to the development and realization of environmentally and socially sustainable business strategies and practices

    Capturing proof process

    Get PDF
    PhD ThesisProof automation is a common bottleneck for industrial adoption of formal methods. Heuristic search techniques fail to discharge every proof obligation (PO), and significant effort is spent on proving the remaining ones interactively. Luckily, they usually fall into several proof families, where a single idea is required to discharge all similar POs. However, interactive formal proof requires expertise and is expensive: repeating the ideas over multiple proofs adds up to significant costs. The AI4FM research project aims to alleviate the repetitive effort by “learning” from an expert doing interactive proof. The expert’s proof attempts can give rise to reusable strategies, which capture the ideas necessary to discharge similar POs. Automatic replay of these strategies would complete the remaining proof tasks within the same family, enabling the expert to focus on novel proof ideas. This thesis presents an architecture to capture the expert’s proof ideas as a highlevel proof process. Expert insight is not reflected in low-level proof scripts, therefore a generic ProofProcess framework is developed to capture high-level proof information, such as proof intent and important proof features of the proof steps taken. The framework accommodates branching to represent the actual proof structure as well as layers of abstraction to accommodate different granularities. The full history of how the proof was discovered is recorded, including multiple attempts to capture alternative, failed or unfinished versions. A prototype implementation of the ProofProcess framework is available, including integrations with Isabelle and Z/EVES theorem provers. Two case studies illustrate how the ProofProcess systems are used to capture high-level proof processes in examples from industrial-style formal developments. Reuse of the captured information to discharge similar proofs within the examples is also explored. The captured high-level information facilitates extraction of reusable proof strategies. Furthermore, the data could be used for proof maintenance, training, proof metrics, and other use cases
