Abstract

Purpose

The purpose of this paper is to propose a soft computing model based on multi-objective evolutionary algorithm (MOEA), namely, modified micro genetic algorithm (MmGA) coupled with a decision tree (DT)-based classifier, in classifying and optimising the students’ online interaction activities as classifier of student achievement. Subsequently, the results are transformed into useful information that may help educator in designing better learning instructions geared towards higher student achievement.

Design/methodology/approach

A soft computing model based on MOEA is proposed. It is tested on benchmark data pertaining to student activities and achievement obtained from the University of California at Irvine machine learning repository. Additional, a real-world case study in a distance learning institution, namely, Wawasan Open University in Malaysia has been conducted. The case study involves a total of 46 courses collected over 24 consecutive weeks with students across the entire regions in Malaysia and worldwide.

Findings

The proposed model obtains high classification accuracy rates at reduced number of features used. These results are transformed into useful information for the educational institution in our case study in an effort to improve student achievement. Whether benchmark or real-world case study, the proposed model successfully reduced the number features used by at least 48 per cent while achieving higher classification accuracy.

Originality/value

A soft computing model based on MOEA, namely, MmGA coupled with a DT-based classifier, in handling educational data is proposed.

Abstract

Gives an in depth view of the strategies pursued by the world’s leading chief executive officers in an attempt to provide guidance to new chief executives of today. Considers the marketing strategies employed, together with the organizational structures used and looks at the universal concepts that can be applied to any product. Uses anecdotal evidence to formulate a number of theories which can be used to compare your company with the best in the world. Presents initial survival strategies and then looks at ways companies can broaden their boundaries through manipulation and choice. Covers a huge variety of case studies and examples together with a substantial question and answer section.

Abstract

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract

Purpose

With the growing interest in behavioral health and medical decision-making, this systematic integrative review aims to understand research on cognitive biases in the context of consumer health information seeking and where future research opportunities may reside.

Design/methodology/approach

Following a systematic review protocol, 40 empirical research articles, out of 1,127 journal research papers from 12 academic databases, from 1995 to 2019, are included for review.

Findings

The study of cognitive biases in consumer health information seeking is a nascent and fast-growing phenomenon, with variety in publication venues and research methods. Among the 16 biases investigated, optimistic bias and confirmation bias have attracted most attention (46.9%). Researchers are most interested in specific disease/illness (35%) and the health factors of consumer products (17.5%). For theoretical presence, about one-third of the reviewed articles have cited behavioral economist Daniel Kahneman, although most of the references are the early works of Kahneman.

Research limitations/implications

As an emerging research area, there exists plenty of cognitive biases to be investigated in the context of health information seeking. In the meantime, the adoption of more recent theoretical insights such as nudge for debiasing may enrich this research area. Health communication scientists may find incorporating the behavioral decision research framework enriches the disciplinary inquiry of health information seeking, while information scientists could use it to commence the cognitive turn of information science evolution.

Originality/value

Through evidence-based understanding, this review shows the potential research directions that health communication scientists and information scientists could contribute to optimize health decisions through the adoption of behavioral decision research framework.

Abstract

The growing importance of entrepreneurship is the result of a global awareness of increasing competitiveness in the business environment. In Singapore, the SME Master Plan (1989) emphasises entrepreneurship as “a key component of the strategy to develop Singapore into a major node in global business and a total business centre.” Much has been reported in the press about entrepreneurship. The article “So You Think We've Arrived?” (Straits Times, 3 Jan 1993) says it all. In the past, Singapore had the temporary sensation of plenty and peace. Singapore industrialised and attracted multinational corporations (MNCs) to leap‐frog the region. This has enabled Singapore to grow at a phenomenal rate. Now, the region has awakened. Our neighbours have learned and are now more competitive to demand a share of the market. The challenge for tomorrow is a more competitive business environment. Our Senior Minister, Mr Lee Kuan Yew, has emphasised that about 15 to 20 percent of Singapore's better graduates must venture abroad if Singapore is to become a developed country (Straits Times, 23 Apr. 1993). Thus, the emerging need for an entrepreneurial spirit has begun and is more real now than ever.

Abstract

Purpose

Interest is increasing in sustainable consumption, including the purchase of used products instead of new ones. This study aims to examine customer behaviors in the context of resale websites. Specifically, it aims to identify the relative role of multidimensional perceived benefits associated with customer attitudes.

Design/methodology/approach

Data are derived from a survey conducted among 169 resale website customers in the USA. Structural equation modeling (using SmartPLS software) is used to examine the hypothesized relationships.

Findings

Results show that epistemic benefits mostly serve to create positive attitudes, followed by economic and functional benefits. However, emotional and social benefits from purchase experience with resale websites fail to influence customers' positive attitudes.

Research limitations/implications

The main limitation of the study lies in the generalizability of findings given that the results and conclusions are based on the study of a single industry. More studies would help to provide a deeper understanding of sustainable consumption across different types of product categories.

Originality/value

This study shows that customers' positive attitudes increase their intention to repurchase from resale websites, suggesting an area of opportunity for resale service providers to design websites to facilitate customer self-expression, to reinforce economic efficiency and to highlight the performance of products and services.

Abstract

E‐commerce plays an important role in today’s business environment, and that role will continue to grow each year. eMarketer predicts that by “2004, world wide e‐commerce revenues are expected to total USD 2.7 trillion”. E‐commerce continues to grow in the United States. “The Census Bureau of the Department of Commerce announced today that the estimate of U.S. retail e‐commerce sales for the first quarter of 2004, not adjusted for seasonal, holiday, and trading‐day differences, was $15.5 billion, an increase of 28.1 per cent (±2.9 per cent) from the first quarter of 2003.” “According to a new study by RoperASW and AOL Time Warner, Europeans spent on average EUR430 on line between August and October 2002.” This compares with an average spend of EUR543 per head in the US over the same period.
