A proposed configurable approach for recommendation systems via data mining techniques

This study presents a configurable approach for recommendations which determines the suitable recommendation method for each field based on the characteristics of its data, the method includes determining the suitable technique for selecting a representative sample of the provided data. Then selecting the suitable feature weighting measure to provide a correct weight for each feature based on its effect on the recommendations. Finally, selecting the suitable algorithm to provide the required recommendations. The proposed configurable approach could be applied on different domains. The experiments have revealed that the approach is able to provide recommendations with only 0.89 error rate percentage.     

Blockchain for tracking serial numbers in money exchanges

Money exchange is one of the most common day‐to‐day activities performed by humans in the daily market. This paper presents an approach to money tracking through a blockchain. The proposed approach consists of three main components: serial number localization, serial number recognition, and a blockchain to store all transactions and ownership transfers. The approach was tested with a total of 110 banknotes of different currency types and achieved an average accuracy of 91.17%. We conducted a user study in real‐time with 21 users, and the mean accuracy across all users was 86.42%. Each user gave us feedback on the proposed approach, and most of them welcomed the idea.

Value relevance of earnings,book value and dividends in an emerging capital market: Kuwait evidence

This study examines the value relevance of book value, earnings and dividends for a sample of all non-financial firms listed on the Kuwait Stock Exchange (KSE) over the period 2003–2009. After controlling for the impact of the global financial crisis, empirical results provide evidence on the value relevance of book value and earnings in the KSE. The results indicate that dividends are not a value-relevant in the presence of earnings in the valuation model. However, when dividends are used as a substitute for earnings they become value-relevant. The explanatory power of the model including both book value and earnings is almost indistinguishable from that of book value and dividends. Furthermore, splitting earnings into dividends declared (or paid) and earnings retained results in each of the two variables becoming value-relevant. The average dividend pay-out ratio tends to increase over time, indicating that dividend policies do matter in the KSE and that dividends in Kuwait are used to boost investors' confidence and support share price, noticeably during the global financial crisis period.     

Religious Charities and Government Funding

The government has the responsibility of providing a social service to its citizens. It decides whether to award funds to a religious nonprofit, secular nonprofit, or to produce the service itself. Religious charities are willing to provide the service at lower costs if they can use the funds as an opportunity to proselytize their doctrine. This proselytizing alters the religious preferences of believers in society. In a situation of equal grants to religious charities, this has the consequence of reducing the number of extremists. Furthermore, conservative religious denominations may discriminate against non-religious individuals in the provision of the social service.     

Inter‐Organizational Learning in Supply Chains: A Focus on Logistics Service Providers and Their Customers

The learning process between supply chain entities is explored from the perspective of senior third‐party executives. Through grounded theory, a theoretical framework emerged that extends our understanding of learning within a supply chain by identifying the major constructs and learning stages comprising the basic social process of inter‐organizational learning. This framework provides significant insights into the complex process employed in a supply chain to share, disseminate, and store information; co‐create knowledge; and to derive a competitive advantage.     

Dynamic price formation in a futures market via double auctions

Summary We report an exploratory study of the process of price formation in a speculative market in the absence of liquidity traders. Traders exchange a futures contract because they interpret information differently. We formulate trading as a sequence of anonymous double auctions and introduce a notion of bounded rationality in which traders use approximate models of market response in forming their bids. We prove existence of a perfect equilibrium in the sequential anonymous auctions game, and show that the equilibrium has a no-regret property. After learning the market price, a trader regrets neither the bid that he made nor the position that he holds. We show that trading volume is related to changes in the distribution of information in the economy. We also show that volume and expected change in price are related to two different attributes of the pattern of private information flow. Fundamentally, no particular relationship between the time series of these variables is always valid for all futures contracts. This point is emphasized by an example.I am thankful for useful comments made by Avraham Beja, James Gammil, Chi-fu Huang, David Scharfstein and three anonymous referees.

Quality management practices and competitive performance: Empirical evidence from Japanese manufacturing companies

This paper presents the results of an empirical study on the relationship between quality management practices and competitive performance in Japanese manufacturing companies. The data was gathered from two surveys including the common sample of twenty-seven Japanese manufacturing companies in the 1990s and the 2000s. Statistical techniques are used to compare the degree of implementation of the eleven quality management practices and their impact on different dimensions of competitive performance between two periods. Findings of this study highlight the stability and consistency of the Japanese quality management, which can be used as one of the strategic weapons for maintaining competitive advantage of Japanese manufacturing companies.     

The Epistemology of Humane Entrepreneurship: Theory and Proposal for Future Research Agenda

This paper proposes a new theory called Humane Entrepreneurship (HumEnt) and identifies areas for future development of knowledge. The new theory integrates in the Entrepreneurial Strategic Posture (ESP) three different concepts: Entrepreneurial Orientation, Sustainable Orientation, and Humane Resource Orientation. From this perspective, HumEnt theory can be considered an extension of previous research but with a new model for consideration. The components of the HumEnt theory and their relationships are outlined in an initial panel of propositions. HumEnt theory can help address the challenges present in creating a more sustainable world. Finally, a research agenda and questions are presented for future consideration.     

Shrinkage estimation of <Emphasis Type="Italic">P</Emphasis>(<Emphasis Type="Italic">X</Emphasis><<Emphasis Type="Italic">Y</Emphasis>) in the exponential case with common location parameter

We consider the problem of estimating R=P(X<Y) where X and Y have independent exponential distributions with parameters and respectively and a common location parameter . Assuming that there is a prior guess or estimate R₀, we develop various shrinkage estimators of R that incorporate this prior information. The performance of the new estimators is investigated and compared with the maximum likelihood estimator using Monte Carlo methods. It is found that some of these estimators are very successful in taking advantage of the prior estimate available.Acknowledgments.
