    [[abstract]]When items are classified according to whether they have more or less of a characteristic, the scale used is referred to as an ordinal scale. The main characteristic of the ordinal scale is that the categories have a logical or ordered relationship to each other. Thus, the ordinal scale data processing is very common in marketing, satisfaction and attitudinal research. This study proposes a new data mining method, using a rough set-based association rule, to analyze ordinal scale data, which has the ability to handle uncertainty in the data classification/sorting process. The induction of rough-set rules is presented as method of dealing with data uncertainty, while creating predictive if—then rules that generalize data values, for the beverage market in Taiwan. Empirical evaluation reveals that the proposed Rough Set Associational Rule (RSAR), combined with rough set theory, is superior to existing methods of data classification and can more effectively address the problems associated with ordinal scale data, for exploration of a beverage product spectrum.[[notice]]補正完畢[[incitationindex]]SCI[[booktype]]紙本[[booktype]]電子

    The Routledge Handbook of Philosophy of Economics

    Get PDF
    The most fundamental questions of economics are often philosophical in nature, and philosophers have, since the very beginning of Western philosophy, asked many questions that current observers would identify as economic. The Routledge Handbook of Philosophy of Economics is an outstanding reference source for the key topics, problems, and debates at the intersection of philosophical and economic inquiry. It captures this field of countless exciting interconnections, affinities, and opportunities for cross-fertilization. Comprising 35 chapters by a diverse team of contributors from all over the globe, the Handbook is divided into eight sections: I. Rationality II. Cooperation and Interaction III. Methodology IV. Values V. Causality and Explanation VI. Experimentation and Simulation VII. Evidence VIII. Policy The volume is essential reading for students and researchers in economics and philosophy who are interested in exploring the interconnections between the two disciplines. It is also a valuable resource for those in related fields like political science, sociology, and the humanities.</p

    A decision support system for animated film selection based on a multi-criteria aggregation of referees' ordinal preferences

    No full text
    International audienceThis paper presents a decision support system devoted to the selection of films for the International Animated Film Festival organized at Annecy, France, every year. It deals with the representation and aggregation of referees' preferences along predefined criteria in addition to their overall selection point of view. The practical requirements associated with this application (often encountered in social or cultural areas as well) are: a common ordinal scale for the criteria scores, a procedure to deal with inconsistencies between criteria and overall scores, explanation tools of each referee's preference model in order to facilitate the deliberation process and also to argument the selection decision. The processing of referees' preferences is achieved thanks to a recent method which consists in finding a generalized mean aggregation operator representing the preferences of a referee, in a finite ordinal scale context. The method allows to deal with consistency conditions on referees' behaviour in order to highlight the criteria or pair of criteria which are the most influential for each of the referees. All the functionalities have been implemented in an interactive decision software that facilitates a shared selection decision. Results issued from the 2007 selection are presented and analysed from the preference representation and processing point of view

    Cultural influences on consumer interactions in the context of electronic commerce

    This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Researchers and academics from diverse disciplines have highlighted the role of 'trust' for establishing and strengthening existing relationships between individuals and organisations in the commercial and the social context. Trust in the cultural context specifically, is credited with being the social 'glue' for sustaining bonds between members of cultural groups. The 'trust' phenomenon has become a 'hallmark' of success for organizations as they become more involved with Information Technology (IT). A precondition for trust to manifest is the natural presence of risk or uncertainties in a potential decision. Since the fears and risks associated with online transactions in the context of ecommerce are high, gaining a customer's trust becomes a must. Some studies have found the ingrained cultural values, which form an essential part of the cultural heritage of a person, to be influential in evoking an individual's trust. Various sources in the marketing and consumer behaviour literature have highlighted the role that religious subcultures play in the purchase decisions of their members. The customs, values, and norms set by a religious group are highly esteemed by its members. The objective of this thesis is to investigate if religious Web sites are more likely to instil trust in online fellow-members than their generic counterparts. From a HCI point of view, we can say that our research will investigate an "abstract" interface of e-commerce systems: the 'theological' interface of a commercial Web site. Consequently, we can also ascertain if religious consumers basing their purchasing decisions on 'religious' trust alone overlook more important issues such as the privacy and security problems associated with financial transactions performed over the Internet. Our empirical findings have discovered that conservative Muslims, who are not very familiar with the Internet, trust a Muslim Web site more than a Christian Web site and a generic Web site. In contrast, conservative Muslims with higher Internet experience were found to be more cautious. They based their 'trust' on more appropriate criteria such as the extent of privacy and security safeguards adopted by a Web site. A qualitative analysis of the post-experimental interviews that we conducted purports that Web-based trust develops with a company's good reputation, previous personal purchasing experiences, and through word-of-mouth recommendations from friends and family or peers. In light of our findings, we argue that the time experience gained in using the Internet plays a major role on how consumers perceive culturally or religiously oriented Web sites. We believe that less experienced Internet users are unaware of the security vulnerabilities inherent in the Internet environment. Therefore, we assume that they are context-blind: they do not differentiate between traditional and the digital marketing environments. Consequently, they would trust purchasing from an electronic store (Web site) in the same manner they would trust purchasing from a 'brick-and mortar' store. In contrast, experienced Internet users deem reputable Web sites adopting good security and privacy safeguards for online transactions to be trustworthier than Web sites designed with a 'religious' interface. We conclude that in the context of e-commerce, one cannot expect to establish a trustworthy commercial relationship based on religious trust alone. From the findings of this study, it has become apparent that the trait of strict religious affiliation seems to disappear in the context of e-commerce. The threats and risks inherent in online transactions seem to restructure the religious community by merging it into a traditional global community of e-consumers. When contemplating a purchase from a Web site, traditional e-consumers pay more attention to the company's reputation and the extent of data security measures adopted by a Web site rather than basing their purchase decisions on the religious affiliations and cultural values taught by parents and ancestors. Thus, Web sites aiming to sell products behind a 'religious' interface could become disappointed. Having said that, we reiterate that the time experience in using the Internet seems to play an influential role in how users' perceive cultural or religious Web sites.Funding was obtained from the Lybian Interest Section

    This Special Issue, entitled "Women in Artificial Intelligence" includes 17 papers from leading women scientists. The papers cover a broad scope of research areas within Artificial Intelligence, including machine learning, perception, reasoning or planning, among others. The papers have applications to relevant fields, such as human health, finance, or education. It is worth noting that the Issue includes three papers that deal with different aspects of gender bias in Artificial Intelligence. All the papers have a woman as the first author. We can proudly say that these women are from countries worldwide, such as France, Czech Republic, United Kingdom, Australia, Bangladesh, Yemen, Romania, India, Cuba, Bangladesh and Spain. In conclusion, apart from its intrinsic scientific value as a Special Issue, combining interesting research works, this Special Issue intends to increase the invisibility of women in AI, showing where they are, what they do, and how they contribute to developments in Artificial Intelligence from their different places, positions, research branches and application fields. We planned to issue this book on the on Ada Lovelace Day (11/10/2022), a date internationally dedicated to the first computer programmer, a woman who had to fight the gender difficulties of her times, in the XIX century. We also thank the publisher for making this possible, thus allowing for this book to become a part of the international activities dedicated to celebrating the value of women in ICT all over the world. With this book, we want to pay homage to all the women that contributed over the years to the field of AI

    An effort to assess the utility of 650 bp Cytochrome C oxidase subunit I (DNA barcode) gene in delineating the members horseshoe crabs (Family: xiphosura) with closely related sister taxa was made. A total of 33 sequences were extracted from National Center for Biotechnological Information (NCBI) which include horseshoe crabs, beetles, common crabs and scorpion sequences. Constructed phylogram showed beetles are closely related with horseshoe crabs than common crabs. Scorpion spp were distantly related to xiphosurans. Phylogram and observed genetic distance (GD) date were also revealed that Limulus polyphemus was closely related with Tachypleus tridentatus than with T.gigas. Carcinoscorpius rotundicauda was distantly related with L.polyphemus. The observed mean Genetic Distance (GD) value was higher in 3rd codon position in all the selected group of organisms. Among the horseshoe crabs high GC content was observed in L.polyphemus (38.32%) and lowest was observed in T.tridentatus (32.35%). We conclude that COI sequencing (barcoding) could be used in identifying and delineating evolutionary relatedness with closely related specie
