Abstract

Purpose

Multi-view fuzzy clustering algorithms are not widely used in image segmentation, and many of these algorithms are lacking in robustness. The purpose of this paper is to investigate a new algorithm that can segment the image better and retain as much detailed information about the image as possible when segmenting noisy images.

Design/methodology/approach

The authors present a novel multi-view fuzzy c-means (FCM) clustering algorithm that includes an automatic view-weight learning mechanism. Firstly, this algorithm introduces a view-weight factor that can automatically adjust the weight of different views, thereby allowing each view to obtain the best possible weight. Secondly, the algorithm incorporates a weighted fuzzy factor, which serves to obtain local spatial information and local grayscale information to preserve image details as much as possible. Finally, in order to weaken the effects of noise and outliers in image segmentation, this algorithm employs the kernel distance measure instead of the Euclidean distance.

Findings

The authors added different kinds of noise to images and conducted a large number of experimental tests. The results show that the proposed algorithm performs better and is more accurate than previous multi-view fuzzy clustering algorithms in solving the problem of noisy image segmentation.

Originality/value

Most of the existing multi-view clustering algorithms are for multi-view datasets, and the multi-view fuzzy clustering algorithms are unable to eliminate noise points and outliers when dealing with noisy images. The algorithm proposed in this paper has stronger noise immunity and can better preserve the details of the original image.

Abstract

Real estate researchers have suggested that the law of diminishing marginal utility applies not only to consumption of property but to the characteristics of the properties consumed as well. Employs a unique data set to empirically model the functional form of the price effects of marginal additions to lot size and view. Shows that the relationships between lot price, size and view are non‐linear, and that marginal price effects diminish as lot size and view quality increase. The results imply that traditional valuation models allow only for the existence of view, rather than the quality of view, and are too simplistic and imprecise. Appraisers should be cognizant of this implication, and devise valuation techniques which allow them to consider differences in the quality of view from property to property.

Abstract

Purpose

Despite a surge in public and academic interest in the social sustainability conduct of firms, only few firms have taken responsibility for the social issues in their supply chains. This study seeks to extend our theoretical understanding of why some firms grow toward accepting this type of responsibility while others do not.

Design/methodology/approach

The authors conduct a systematic literature review for the purpose of theory building. Building on Gao and Bansal's distinction of instrumental and integrative views on business sustainability (2013, DOI 10.1007/s10551-012-1245-2) as well as corporate social responsibility development research, the authors review socially sustainable supply chain management (social SSCM) literature to theorize the interplay of driving factors that underly firms' choice to refrain from, start or deepen their engagement in social SSCM.

Findings

The authors propose an overview of the presumed mechanisms underlying the development of a reluctant, a purely instrumental or an integrative view on social SSCM. Among other things, the authors propose that it seems highly unlikely for conventional, profit-oriented firms to develop beyond an instrumental view on social SSCM.

Originality/value

This study conceptually extends current research on social SSCM by offering insights on how firms are driven to engage in it. This study offers first thoughts that should help managers and other stakeholders better understand the social SSCM potential of firms and how to realize this potential effectively.

Abstract

Purpose

This study provides a framework to explain the attitude–intention gap in viewing advertisements in social networks. Going beyond the literal and evaluative inconsistency issues in measuring factors with theory of planned behavior (TPB), the authors propose and test a theoretical framework with possible moderators to the relationship between the attitude and behavioral intention.

Design/methodology/approach

Two surveys were conducted to test the theoretical framework, one with students and the other with working people in Hanoi, Vietnam. After testing measure reliabilities and validities, hypotheses were tested with regressions using SPSS.

Findings

In general, the attitude was still found to have a positive relationship with the behavioral intention. However, the attitude–intention gap still exists as trust in social network was found to moderate the relationship between the attitude and intention with the working people sample while trust in brands advertised facilitate the relationship with the student sample. Interestingly, involvement was not found to moderate the relationship.

Practical implications

Several practical implications can be recommended. In general, the marketing strategy for managers is still to develop positive attitude by consumers toward viewing advertisements. However, personalization strategy should be taken with care in advertisement in social network. Providing consumers with perceived privacy control may help enhance the advertisement effectiveness. Finally, building trusts, on or off the social network, should be optimized to increase the users' intention to view advertisements in social network.

Originality/value

This research offers a new explanation for the attitude–intention inconsistency in general and for viewing advertisements in social networks in particular. Going beyond the measurement issues, the research suggests looking at the process under that the attitude can be formed and activated to impact on the intention. Moreover, mixed findings from two comparable samples provide nuanced insights for different groups of consumers.

Abstract

Despite the widely varying estimates about the strength of the global Internet economy, there is general agreement among experts about the dramatic influence of this medium on consumers as well businesses. However, one area that has generated conflicting views is the issue of Internet privacy. As businesses develop more sophisticated technologies to collect, store and disseminate information on consumers, privacy and security of this information are raising concerns among consumers and public policy advocates. Anecdotal evidence seems to suggest that consumers in some European countries view privacy protection as a very important issue. Investigates consumer attitudes in the Federal Republic of Germany. The findings indicate that consumers in Germany have very strong views about protecting their privacy. They believe that both companies and governments are obligated to protect the information of their consumers and citizens. To this end, German consumers are willing to support stricter legislation. Results also suggest that German consumers’ views about Internet use and on‐line behaviors, are affected, among other things, by their views regarding privacy in general, their personal expertise in Internet technologies, and how they view the role of the government and the role of companies in protecting consumer privacy.

Abstract

In order to succeed in an action under the Equal Pay Act 1970, should the woman and the man be employed by the same employer on like work at the same time or would the woman still be covered by the Act if she were employed on like work in succession to the man? This is the question which had to be solved in Macarthys Ltd v. Smith. Unfortunately it was not. Their Lordships interpreted the relevant section in different ways and since Article 119 of the Treaty of Rome was also subject to different interpretations, the case has been referred to the European Court of Justice.

Abstract

The World Wide Web has undergone a rapid transition from the originally static hypertext to an ubiquitous hypermedia system. Today, the Web is not only used as a basis for distributed applications (Web applications), moreover it serves as a generic architecture for autonomous applications and services. Many research work has been done regarding the modeling and engineering process of Web applications and various platforms, frameworks and development kits exist for the efficient implementation of such systems. Concerning the modeling process, many of the published concepts try to merge traditional hypermedia modeling with techniques from the software engineering domain. Unfortunately, those concepts which capture all facets of the Web’s architecture become rather bulky and are eventually not applicable for a model‐driven Web application development. Moreover, there is a need for frameworks which address both, the modeling process and the implementation task and allow a model driven, semi‐automatic engineering process using CASE tools. This paper outlines the DaVinci Web Engineering Framework which supports the modeling as well as the semi‐automated implementation of Web applications. The DaVinci Architectural Layer specifies a persistent, hierarchical GUI model and a generic interaction scheme. This allows the elimination of the hypermedia paradigm, which turned out to be rather practical when building Web applications.

Abstract

Purpose

The purpose of this paper is to explore the social and cultural aspects of the context that frames service exchange to better understand how value and experience are evaluated.

Design/methodology/approach

The authors apply a conceptual approach to develop and propose a framework for deepening the understanding of the context of market-related experiences. The authors integrate two growing streams of research – consumer culture theory and service-dominant logic – that focus on phenomenological and experiential views on value and extend the context of experience with a culturally rich, service-ecosystems view of markets.

Findings

The authors broaden the context of experience by applying a service-ecosystems perspective and identify four social and cultural factors that influence experience from this extended context – sign systems and service ecosystems; multiplicity of structure and institutions; value-in-cultural-context; and co-construction of context. Based on this, the authors point toward directions for future research.

Research limitations/implications

The proposed framework points researchers and managers toward an extended context that is reproduced through the co-creation of value and influences evaluations of experience. Empirical research is needed to provide evidence of the proposed framework and further extend the understanding of dynamic social and cultural contexts.

Practical implications

The findings of this study provide a broader scope of context and identify additional social and cultural factors for managers to consider in their efforts to enhance customer experiences.

Originality/value

Traditional views of markets limit the context of experience to firm-customer encounters or consumer-centric practices and processes. This paper extends the context of experience to consider the practices and perspectives of multiple actors and various views on value.

Abstract

A collection of essays by a social economist seeking to balance economics as a science of means with the values deemed necessary to man′s finding the good life and society enduring as a civilized instrumentality. Looks for authority to great men of the past and to today′s moral philosopher: man is an ethical animal. The 13 essays are: 1. Evolutionary Economics: The End of It All? which challenges the view that Darwinism destroyed belief in a universe of purpose and design; 2. Schmoller′s Political Economy: Its Psychic, Moral and Legal Foundations, which centres on the belief that time‐honoured ethical values prevail in an economy formed by ties of common sentiment, ideas, customs and laws; 3. Adam Smith by Gustav von Schmoller – Schmoller rejects Smith′s natural law and sees him as simply spreading the message of Calvinism; 4. Pierre‐Joseph Proudhon, Socialist – Karl Marx, Communist: A Comparison; 5. Marxism and the Instauration of Man, which raises the question for Marx: is the flowering of the new man in Communist society the ultimate end to the dialectical movement of history?; 6. Ethical Progress and Economic Growth in Western Civilization; 7. Ethical Principles in American Society: An Appraisal; 8. The Ugent Need for a Consensus on Moral Values, which focuses on the real dangers inherent in there being no consensus on moral values; 9. Human Resources and the Good Society – man is not to be treated as an economic resource; man′s moral and material wellbeing is the goal; 10. The Social Economist on the Modern Dilemma: Ethical Dwarfs and Nuclear Giants, which argues that it is imperative to distinguish good from evil and to act accordingly: existentialism, situation ethics and evolutionary ethics savour of nihilism; 11. Ethical Principles: The Economist′s Quandary, which is the difficulty of balancing the claims of disinterested science and of the urge to better the human condition; 12. The Role of Government in the Advancement of Cultural Values, which discusses censorship and the funding of art against the background of the US Helms Amendment; 13. Man at the Crossroads draws earlier themes together; the author makes the case for rejecting determinism and the “operant conditioning” of the Skinner school in favour of the moral progress of autonomous man through adherence to traditional ethical values.
