Marketing Approach

PurposeThis study explores why consumers view ambush marketing as an ethical marketing approach.Design/methodology/approachA qualitative study was devised to investigate what ambush marketing means to those consumers who find it ethical or are not annoyed by it. Data were collected via focus groups.FindingsThree main themes emerged from the data analyses. The most dominant theme was Machiavellianism. Favorable evaluations of ambush marketing lean on a Machiavellistic understanding. The second was the Robin Hood effect, which is observed when the ambusher is a smaller or local brand. In the third theme, ambush attacks are considered as charismatic or enjoyable action, in what is termed dark charisma.Practical implicationsFindings of the current study suggest considerable implications both for businesses that deal with sponsorship and for organizing committees.Originality/valueThe extant literature on consumers' attitudes toward ambush marketing mostly focuses on ethical issues and/or the effectiveness of ambush marketing (i.e. harm to official sponsors), using qualitative techniques. However, the literature is devoid of studies exploring consumers' perception on ambush marketing, and more specifically, explanations of what is ethical and unethical from consumers' point of view. To best of the author's knowledge, it is the first study that seeks an explanation about consumers' positive evaluation of ambush marketing.

Purpose The purpose of this paper is to present a comparison between reluctance synchronous machine-enabling work at high internal temperature (HT° machine) with laminated and solid rotor. Design/methodology/approach To obtain heat sources for the thermal model, calculations of the electromagnetic field were made using the Opera 3D program including effect of rotation and the resulting eddy current losses. To analyse the thermal phenomenon, the 3D coupled thermal-fluid (CFD) model is used. Findings The presented results show clearly that laminated construction is much better from a point of view of efficiency and temperature. However, solid construction can be interesting for high speed machines due to their mechanical robustness. Research limitations/implications The main problem, despite the use of parallel calculations, is the long calculation time. Practical implications The obtained simulation and experimental results show the possibility of building a machine operating at a much higher ambient temperature than it was previously produced for example in the vicinity of the aircraft turbines. Originality/value The paper presents the application of fully three-dimensional coupled electromagnetic and thermal analysis of new machine constructions designed for elevated temperature.

Purpose This paper aims to study whether the recycling of a third party competes with the trade-in service of a manufacturer, and explores the optimal trade-in and third-party collection authorization strategies for the manufacturer. Design/methodology/approach According to whether to authorize a third party to collect its used products, the manufacturer has two choices: one is not authorization (NA); the other is authorization (A). This paper uses profit-maximization model to investigate the optimal decisions of the manufacturer and the third party under NA and A, respectively, and then explores which choice is better for the manufacturer. Findings It is observed that there is a competition between trade-in service and third-party recycling when the durability parameter of the used product is relatively small. Moreover, when the durability parameter of the used product is relatively large, A is always better choice for the manufacturer; otherwise, NA is a better choice except for the case that the unit trade-in subsidy is low and the salvage of the used product is high. Practical implications These results provide managerial insights for the manufacturer and the third party to make decisions in the field of recycling. Originality/value This paper is among the first papers to study the competition between trade-in program and third party’s collecting program under government’s trade-in subsidy policy. Moreover, this paper presents the conditions under which the manufacturer should authorize or not authorize the third party to collect its used products.

Purpose Starting from the state-of-the-art of Fintech development, this study aims to propose some research propositions comparing reward-crowdfunding (RCF) and equity-crowdfunding (ECF). In this sense, the present research provides a comprehensive analysis of fintech development and – to conceptualize the comparison between RCF and ECF – it focuses on campaigns’ characteristics, aims and post-campaigns scenarios. Design/methodology/approach All the research propositions related to the comparison between RCF and ECF are rooted in dedicated literature. The methodological approach adopted in the present paper can be referred to theorizing. Findings This study suggests that five key elements characterize the development of fintech: regulation, infrastructure, technologies, finance and innovations. The research provides nine propositions: four related to the campaigns’ characteristics; two related to the use of crowdfunding models by entrepreneurs; and three related to the performance of crowdfunded companies. Practical implications By offering nine research propositions, this study is expected to foster and support the investigation of fintech development from an entrepreneurial and managerial point of view. Originality/value To the best of authors’ knowledge, this study is among the first to explore the fintech development and to propose a comparative approach between RCF and ECF. This research contributes to the current debate on fintech development as well as on the comparison between crowdfunding models.

Purpose This study aims to evaluate if soya consumption can compromise or positively influence the effects of the Mediterranean diet (MD). Design/methodology/approach A full literature review has been conducted as part of a proposal of a new point of view on the consumption of soya and its derivatives in areas where until a few decades ago this type of food did not exist at all. Findings There does not seem to be any contraindications for soy systematic use, therefore, excluding historical-geographical reasons, soya could be included in an MD without altering the benefits associated with it. Practical implications Soya is not advised as a typical food in the MD, but promoting its use could probably contribute to increase the variety of the diet and likely consolidates the positive health benefits characteristic of MD. Originality/value To the best of the authors’ knowledge, this review is one of the first to evaluate soybean consumption within the MD.

PurposeEstablishing peace, security and discipline for individuals, nations and states in contemporary international order is of the highest importance at the present time. Regularization should be done through approaching natural rights of individuals and also through observing humanistic characteristics and ethics. The aim of this paper is to introduce a legal base to promote international relations. Design/methodology/approachA draft for International Relation Declaration based on Islamic Sufi teachings has been compiled, and actually it is an abstract of an extended survey on the subject and opinions in relation to the current international problems. FindingsThis draft has been codified in three main topics of public international law, foreign policy and diplomacy. Research limitations/implicationsTo conclude the draft, it should be scrutinized by many scholars in different disciplines, in the next step. Practical implicationsAs the mystical characteristics of Sufism and Gnosticism of all religions (Tariqa) are all united and based upon love towards the Creator and consequently towards the creatures of God, these provisions could be agreed upon and put into practice. Social implicationsDelicateness, truthfulness and righteousness of Islamic Sufism, which is the gist of all those elites’ divine messages for thousands of years, one after another, can be of a great help to regulate international relations. Originality/valueInternational Law scholars have not looked at this subject matter from the Sufism viewpoint. This paper will shed a light on this point of view from other angles related to the international law such as politics, law and institutions.

Purpose – This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies. Design/methodology/approach – This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context. Findings – Globalization has inspired and created numerous questions, including many within the realms of human resource development (HRD). However, the focus of these questions tends to be from the point of view of developed nations and the effect on either their own HRD issues, and rarely consider what the effects are on developing nations and their HRD activities and policies. Yet, these questions should not be pushed to the back of the queue, as the extent to which HRD can progress effectively is dependent on both sides of the equation. Practical implications – The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations. Originality/value – The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Group Recall

Purpose The purpose of this paper is to present a review on the use of the recall metric for evaluating information retrieval systems, especially search engines. Design/methodology/approach This paper investigates different researchers’ views about recall metrics. Findings Five different definitions for recall were identified. For the first group, recall refers to completeness, but it does not specify where all the relevant documents are located. For the second group, recall refers to retrieving all the relevant documents from the collection. However, it seems that the term “collection” is ambiguous. For the third group (first approach), collection means the index of search engines and, for the fourth group (second approach), collection refers to the Web. For the fifth group (third approach), ranking of the retrieved documents should also be accounted for in calculating recall. Practical implications It can be said that in the first, second and third approaches, the components of the retrieval algorithm, the retrieval algorithm and crawler, and the retrieval algorithm and crawler and ranker, respectively, are evaluated. To determine the effectiveness of search engines for the use of users, it is better to use the third approach in recall measurement. Originality/value The value of this paper is to collect, identify and analyse literature that is used in recall. In addition, different views of researchers about recall are identified.
