This is also evident in sports games where players have a very limited time to obtain, interpret and analyze information on ever-changing situations before they decide on their actions. Using common basketball game scenarios, this research compares and evaluates decisions made by novice and experienced basketball players of different ages. Adapted from the decision-making test developed by McMorris and Graydon in 1996, this computer-based test comprises 25 common basketball game scenarios, of which 20 are unique, and 5 are repeated for consistency checks. For each scenario, participants decide if the player with the ball should hold on to the ball, pass it to another team mate, dribble the ball or attempt a shot. The participant's choice of action and the time taken to make the decision are the dependent variables analyzed. All 20 unique scenarios were reviewed by expert coaches with at least 10 years of coaching experience. We identified 10 of these scenarios as straight-forward (easy) as all the coaches agree on the same choice of action. The remaining 10 scenarios are deemed as ambiguous (difficult) as the coaches have differing views on the best choice of action for the scenario. In this paper, we investigate how the decisions made by players differ from that of coaches and the time taken to decide.

Six sigma's success in manufacturing is well published. But the same cannot be said about its implementation in services. Applying six sigma to services is still limited to only a small number of services. This paper reviews the application of six sigma in service industries. Emphasis is given to application issues such as what are necessary critical success factors and key performance indicators in order for a project to be successful. A pilot study was carried out in order to highlight the issues discussed. Regardless of the service that is provided, a number of guidelines can be commonly applied to varying types of services. The aim of this paper is to help widen the scope of six sigma application in services.

There are suggestions that the developing antecedents would differ between service firms and product firms. However, there are also other means for business categorization, and the antecedents have rarely been studies globally. In this study, framework for future research is proposed based on literature review. The antecedents are grouped as “BASICs”: backdrop, atmosphere, supporting system, internal enablers, and customer-related factors. They are suggested to be affected by offering nature, offering variety, and service mode. We also suggested the methods for data collection and analysis. Expectations on the results are also stated.

This paper discusses an integrative framework that incorporates the Kano model, Markov chain, and quality function deployment (QFD) into Kansei engineering (KE). Its purposes are: 1 to exhibit the relationship between service performance and Kansei 2 to enable service designers to establish the extent to which they prioritise their improvement programmes in dealing with current and future preferences. Incorporating Markov chain modelling and QFD into Kansei engineering 75 A comprehensive case study involving Indonesian, Japanese, and Singaporean tourists, was carried out. Understanding the cultural differences with respect to Kansei evaluation will yield valuable insights for international marketing strategies.

The IC(50) of wheatgrass-treated HL60 (17.5 ± 1.1, 12.5 ± 0.3, and 16 ± 0.5 microgram/ml for 24, 48 and 72 h, respectively) and fibers-treated HL60 (86.0 ± 5.5, 35.0 ± 2.5, and 52.5 ± 4.5 microgram/ml for 24, 48 and 72 h, respectively) showed that both extracts possessed optimum effect after 48 hours of treatment. No significant cytotoxic effect was observed on other type of cells. For trypan blue dye exclusion method, wheatgrass reduced the number of viable cells by 13.5% (±1.5), 47.1% (±3.6), and 64.9% (±2.7) after 24, 48 and 72 h exposure, respectively. Mixture of fibers reduced the number of viable cells by 36.4% (±2.3), 57.1% (±3.1), and 89.0% (±3.4) after 24, 48 and 72 h exposure, respectively, indicated that necrosis is also an alt...

This was done by reviewing and evaluating the methodological approaches and the geographical affiliations of authors published in the selected journals. A sample of top journal in service research is selected based on previous literature. The review and evaluation considers all papers published in selected journals over a 14 year period from 1995 to 2008. The papers are categorized and the geographical affiliations are noted. The analysis revealed that Taiwan is the major contributor in service related articles followed by Singapore, Hong Kong, and South Korea. This is the first review and analysis of contribution from Asian institutions in top journals of service research. The study provides valuable insights into the nature of academic publishing by authors from Asian institutions in the burgeoning area of service science.

However, with the development of service industries, the ineffectiveness in IP protection becomes manifest. Meanwhile, other knowledge protecting methods enable companies to maintain their competency without formal protection. This study examines the effectiveness of different means of knowledge protection. Specifically, business is classified according to companies' offering nature, serving mode and consider about their business hardware. The effectiveness of protection methods is analyzed among these business types. Interviews were conducted with senior managers of 39 companies in China and Singapore. It is demonstrated that the choice of knowledge protecting method does not depend mainly on whether a company provides products or services, but on how the company produces and provides its offerings. It is found that the core competency of companies largely affects their attitude on whether to protect their offerings. It is found that in weak appropriability regimes, companies apply for patents not for their knowledge protection function, but for other benefits, such as getting awards or tax reductions, and improving reputation among customers.

This research investigates the use of six sigma tools and techniques in service organizations and examines its effect on NSD performance. The results of the research illustrate that by using the six sigma methodology in new service development, firms can experience greater efficiency in their development processes with regards to improved financial results and higher customer satisfaction.

Products and services need to offer features and properties which can make them distinguishable and attractive to customers. Emotions and feelings are prominent during product interaction and service encounter. Kansei Engineering (KE) enables interpretation and translation of customer emotions into design parameters. The application of KE covers both products and services design. Besides dealing with attractive exterior appearances, KE has an ability to optimize properties that are not directly detectable or visible, such as the comfort of hospital and concert hall. There are few empirical studies. Kansei management should recognize cultural differences in Kansei. However, for analysis of cultural values we need to understand the different needs of different customers. A study of luxury hotel services for Indonesian, Japanese and Singaporean tourists, was conducted using interviews and a tri-lingual face-to-face questionnaire. 425 responses were collected. Japanese tourists were found to be the most Kansei-oriented. They tended to value luxury hotels as "clean" and "quiet" places to stay. Indonesian and Singaporean tourists shared a common response to the Kansei word "elegant" which correlates with their common cultural dimension of "power distance". Incorporation of cultural issues into Kansei studies can provide marketing strategies for customers of different cultural backgrounds.

We base our analysis on tools of quantum information theory such as entanglement and the majorization criterion for probability distributions. In particular we scrutinize a recent interesting hypothesis by C. K. Law in the Ref. Phys. Rev. A 71, 034306 (2005) that suggests that the amount of entanglement between the constituent fermions is related to the bosonic properties of the composite boson. We show that a large amount of entanglement does not necessarily imply a good boson-like behaviour by constructing an explicit counterexample. Moreover, we identify more precisely the role entanglement may play in this situation.
