Development of a process mining system for supporting knowledge discovery in a supply chain network

In today's competitive environment, business organizations are forced to maintain their competitive advantage by their ability to cut costs, increase revenue and uncover hidden issues. In order to enhance the visibility and transparency of value added information in a supply chain network, a process mining system is proposed for discovering a set of fuzzy association rules based on the daily captured logistics operation data, within the network. The proposed methodology provides all levels of employees with the ability to enhance their knowledge and understanding of the current business environment. Once interesting association rules have been extracted, organizations can identify the root-causes of quality problems in a supply chain and improve performance by fine-tuning the configuration of process parameters in specified processes. The application of the proposed methodology in a case company has also been studied. The prototype system has been developed and evaluated after performing a spatial analysis. The results obtained indicate that the system is capable of extracting high-quality and actionable information in the case company.     

A global database of domestic and international tourist numbers at national and subnational level

We present a new, global database on tourist destinations. The database differs from other databases in that it includes both domestic and international tourists; and it contains, for the most important destinations, data at national level as well as at lower administrative levels. Missing observations are interpolated using statistical models. The data are freely accessible on the internet. Copyright © 2007 John Wiley & Sons, Ltd.     

Strategic orientation of high-technology firms in a transitional economy

Strategic orientation is a critical factor for a firm's competitiveness in a transitional economy context but it is understudied in the current literature. This article examines the antecedents of strategic orientation from both the socio-cognitive and resource-based view perspectives. The study posits that the strategic orientations of firms in a transitional economy context are influenced by the top managers’ cognitions and organizational resources. Based on a national survey of high-technology firms in China, the study finds that a stronger market-focused strategic orientation was facilitated by managerial cognitions about the future of the industry and current operation and performance of the firm, as well as organizational resources including an R&D infrastructure, technological alliance, and top managers' foreign experience. The study confirms that strategic orientations should be examined from multiple theoretical perspectives.     

A Step Forward: Ethics Education Matters!

Ethics education matters! Contrary to some common beliefs that ethical behavior is inborn, this study suggests that education does matter. This paper examines ethics education and its relationship with students’ ethical awareness and moral reasoning. Attitudes Towards Business Ethics Questionnaire and 10 vignettes were deployed as the major measurement instruments. It is hypothesized that students with ethics education will have both a greater ethical awareness and ability to make more ethical decisions. Hypotheses were tested in two undergraduate business courses at a major research university where 707 students were sampled. Results suggest that ethics education improved students’ ethical awareness and moral reasoning. Interestingly, results also seem to show that students’ readiness moderated their learning outcomes.     

Bootstrap ARDL on energy-growth relationship for 22 OECD countries

Applying a recent bootstrap autoregressive distributed lag method, this article re-examines the energy-growth relationship for 22 OECD countries over the period 1966–2013. The empirical results suggest degenerate cases for eight countries. Only Japan is truly cointegrated. Some causality patterns are identified.     

Introducing cable television into Hong Kong : Political and economic implications

This paper seeks to evaluate and predict the impact of the introduction of cable television into Hong Kong, a densely populated and highly dynamic Asian metropolis currently under British administration. The discussion will focus on how the coming of cable communication will impact on the ownership and economic structure of the broadcasting industry, with particular reference to international participation; public policy issues concerning economic structure and programming of the cable system; and the implications for the period of Hong Kong's political transition from the UK to China.     

Using stochastic growth models to understand unit roots and breaking trends

This paper provides economic underpinnings for some recent econometric models of unit roots and breaking trends. It shows that in an endogenous growth model, difference stationarity is present in every growing variable; and this phenomenon is generated by the propagation mechanism of the model. For an exogenous growth model, either difference stationarity or trend stationarity may be present, depending on the nature of external impulses. Regarding long-run growth rates, permanent changes in economic fundamentals lead to segmented trends in endogenous growth models, but only shifting trends in exogenous growth models.     

What's wrong with executive compensation? A roundtable moderated by Charles Elson

The value that many superpaid CEO superstars supposedly created has largely disappeared, and the likelihood that it will be recovered anytime soon seems remote. On top of that, a good number of top executives treated their companies like ATMs, awarding themselves millions of dollars in corporate perks. It's hard to dispute the idea that executives were corrupted by the sums of money dangled in front of them. What's wrong with executive compensation, and what can we do about it? HBR and the University of Delaware's Center for Corporate Governance convened a round-table of compensation experts last October on the university's campus in Newark, Delaware. The 12 panelists, from CEOs to investors, from the professionals who advise them to a chief justice who rules on their disputes, provided an extraordinary diversity of viewpoints. The panelist began by debating ways to align the interests of the senior executives with the long-term interests of the company-weighing the relative benefits of stock options versus stock grants, for instance. But the discussion expanded to cover broader questions of corporate governance and company values. "The main reason compensation increases every year is that most boards want their CEO to be in the top half of the CEO peer group," said Ed Woolard,Jr., a former CEO of DuPont. And compensation lawyer Joe Bachelder pointed out the danger of structuring pay in such a way that it dampens risk taking among executives. It was a lively and wide-ranging discussion of one business's most pressing issues.     

MULTIATTRIBUTE UTILITY THEORY,INTERTEMPORAL UTILITY,AND CORRELATION AVERSION

Convenient assumptions about qualitative properties of the intertemporal utility function have generated counterintuitive implications for the relationship between atemporal risk aversion and the intertemporal elasticity of substitution. If the intertemporal utility function is additively separable, then the latter two concepts are the inverse of each other. We review a theoretical specification with a long lineage in the literature on multi‐attribute utility and use this theoretical structure to guide the design of a series of experiments that allow us to identify and estimate intertemporal correlation aversion. Our results show that subjects are correlation averse over lotteries with intertemporal income profiles.
