本文基于模拟方法比较了不同非线性时序模型的LM检验的功效和规模,同时也考虑一般化线性检验BDS检验参与比较,目的在于探讨蒙特一卡洛渐近法检验与自举法（bootstrap）检验的两类临界值的统计功效何者更为有效。通过实证与对比分析,结果表明,当样本小于200或自回归系数接近单位根,或者线性性检验是ARCHT或BDS时,就可以考虑应用自举法临界值而非渐近临界值。而且还发现,BDS检验仅在一般性上优于LM检验。 相似文献

Even though development organizations provide access to working capital and enterprise development training, they often fail to improve the socio-economic condition of low-income households. One of the factors contributing to the failure of development programs is their lack of capacity to measure the entrepreneurial potentials among the low-income participants. This study focused on the development of an entrepreneurial index that measures the entrepreneurial potentials among low-income households. Adopting a cross-sectional design, a total of 403 micro-entrepreneurs were approached from the list provided by ‘Majlis Amanah Rakyat’ and ‘Majlis Agama Islam Dan Adat Istiadat’, Kelantan. This study used formative hierarchial model to determine the local and global weights for all the items used to develop the index. Further, the nomological validity revealed a positive effect of entrepreneurial index on entrepreneurial competency, enterprise performance, and enterprise sustainability. 相似文献

Abstract Local governments in many countries are implementing administrative reforms within the framework of New Public Management (NPM) in order to improve the quality and productivity of public services. The use of performance indicators and benchmarking facilitates evaluation of efficiency regarding the provision of such services and favours the acquisition of better practices. The problems that may arise in the introduction of performance indicators in local government mainly concern the consensual design and standardization of indicators for various entities, the method to be used for calculations and the selection of analytical criteria to be applied to the values obtained. In this article, we identify obstacles that may be encountered in achieving a standardized definition of performance indicators within local government and, on the basis of learning from the practical experience of several large city councils in Spain, formulate strategies to resolve these problems, taking note of the viability and real efficacy of the solutions adopted. 相似文献

Small and medium sized enterprises (SMEs) play an important role in any economy as they contribute to GDP and employment. However, sustainability (right combination of economic, environmental and social) of SMEs is a major concern as they prioritize economic performance over environmental and social to remain competitive. Majority of prior researches on SMEs' sustainability either look at the impact of a few limited enablers (e.g. lean, green, innovation etc.) on sustainability performance or the effect of pressures and barriers on the sustainability performance. There is a clear gap of a holistic and robust framework for sustainability performance analysis in order to measure and improve sustainability performance. This research bridges this knowledge gap by addressing two research questions – what practice and performance criteria are being considered for sustainability performance analysis in a broad environmental, economic and social context, how are they related, and what methods are being used to derive the relationship between sustainability practices and performance. These research questions are addressed through a systematic literature review of 58 papers, published between 2005 and 2018 in leading journals. First, an objective content analysis is undertaken in order to identify sustainability practices and performance criteria along with their frequency of usage in prior research. Second, the correlation among the variables is studied. Third, the methods for analyzing the relationships of the criteria are identified. Finally, a framework for analysing correlation of SMEs’ sustainability practices and performance in order to measure and improve performance using statistical modeling approach is proposed. 相似文献

O wad some Power the giftie gie us To see oursels as ithers see us! It wad frae mony a blunder free us , An' foolish notion:– – Robert Burns, “To a Louse”.The stated purpose of this conference contains the provocative assertion that “[Statistics] does not receive the recognition it needs – as a vital part of making progress in _business and industry_” I agree. I believe that there is a significant divide between senior management in business and industry (Them), and the statisticians (Us) who work on business and industrial problems: in a sense–to borrow from George Bernard Show–two groups divided by lack of a common language. A lot of their words aren't in our vocabulary, and a lot of our words aren't in theirs. Such is not the case in many other major domains of statistical practice–Government, Insurance, Medicine to name but three. Why is this so and what can we do about it in Business and Industry? This paper seeks to explore these questions, and to argue that their resolution will involve a sustained commitment by the Statistics profession to areas such as statistical education, public awareness, and promoting professionalism in the practice of Statistics. However, the most important commitment might need to be that the Statistics profession take Robert Burns to heart. 相似文献

The purchasing of management consulting services is a challenging area for purchasing agents to become involved in. A study of six organizations shows large variations in terms of the extent and way in which they were involved ranging from ad hoc and clerical approaches to their systematic and central participation. Based on a comparison of the cases, enablers of purchasing involvement are discussed, including the status of the purchasing function, managerial use of and attitudes towards consultants, how the management consulting service and the purchasing situation are framed, and the implementation strategy. We conclude that what are generally regarded as sound purchasing practices can also work in the case of management consultants. This, however, requires a good understanding of the consulting service in the client organization. We suggest that the traditionally marginal role of purchasing agents may be better understood as a consequence of the characteristics of the consultant–client relationship than any essential characteristics of the consulting service. 相似文献

Measuring organizational performance is difficult, especially when what has to be measured keeps changing. Sustainability concepts have dramatically widened the scope of measurement options and leading organizations are grappling with sustainability reporting, but there is no sign of consensus on a common reporting standard and the competing frameworks are impossibly complex. This paper recognizes that measuring sustainable performance has to be conceptually based but simplified to be practically useful. It proposes a stakeholder‐based, Sustainable Balanced Scorecard (SBSC) conceptual framework coupled with a single‐measure Organizational Sustainability Performance Index to integrate the measures in the SBSC. The Index helps make sustainable organizational performance measurable and accessible to stakeholders. Copyright © 2006 John Wiley & Sons, Ltd and ERP Environment. 相似文献

This research adopts the institutional and relational view theories to empirically test the impact of organisational culture (OC) on sustainable supply chain performance (SSCP) and further examines the impact of external integration on their relationship, drawing on a study in the food manufacturing industries in the UK and Greece. Using the mixed method approach, structural equation modelling (SEM) technique was first used to empirically analyse the data from a survey of 315 firms. In addition, insights from 11 interviews from top managers were qualitatively used as the basis to enrich and confirm the findings from the quantitative study. Our findings revealed that in the context of global supply chains only developmental, hierarchical, and group culture components of the competing values framework (CVF) as a model for assessing OC are conducive for achieving a higher SSCP. Although developmental, hierarchical and group cultures are instrumental for SSCP, a strong external integration is still required. Thus, external integration was found to mediate the relationship between the dimensions of OC and SSCP. The results further confirmed a positive relationship between all the dimensions of OC (developmental, group, hierarchical and rational culture) and external integration and a positive impact of external integration on SSCP. This research expands the institutional and relational view theories to examine the effect of OC (using CVF) on SSCP and further reveals the extent of external integration needed in the relationship to enhance SSCP in global supply chains. Supply chain managers are encouraged to adopt integrated competing values, namely, developmental, group, and hierarchical cultures to intensify the external integration in the supply chain to overcome several sustainability challenges and improve SSCP. 相似文献

This paper utilizes a large universe of 18,410 technical trading rules (TTRs) and adopts a technique that controls for false discoveries to evaluate the performance of frequently traded spreads using daily data over 1990–2016. For the first time, the paper applies an excessive out-of-sample analysis in different subperiods across all TTRs examined. For commodity spreads, the evidence of significant predictability appears much stronger compared to equity and currency spreads. Out-of-sample performance of portfolios of significant rules typically exceeds transaction cost estimates and generates a Sharpe ratio of 3.67 in 2016. In general, we reject previous studies’ evidence of a uniformly monotonic downward trend in the selection of predictive TTRs over 1990–2016. 相似文献

Abstract In public domains, performances – also in ambiguous fields like policing – are controlled, by making them transparent, by comparing them, and by linking them to targets. Although this ‘numerical capture' of complex phenomena has been heavily criticized, management by measurement is blossoming and in specific cases, measurements like crime monitoring have played a role in reducing crime. The question, however, is whether such improvements are caused by distinctive measurement methods, or by ‘something else'. This paper will analyze how one particular measurement method, the so-called Rotterdam ‘Safety Index', contributed to safety policies. It will show how this dubious instrument is made meaningful; how, indeed, ‘something else' is at work. Political and administrative key players made certain moves in order to ‘link', ‘store', and ‘advocate' the Safety Index. These acts, moreover, occurred amidst distinctive socio-political conditions. Because of ‘acts in context', the Index became a workable tool, producing tangible effects. 相似文献
