Purpose – Seam efficiency plays an important role for obtaining a desired seam quality. Therefore, this issue is often referred in research papers. The purpose of this paper is to determine the seam strength and efficiency as well as examining, if and how such factors as: a kind of fabric, kind of thread, kind of seam and the stitch density influence the transverse seam strength and the seam efficiency. Design/methodology/approach – For research four types of polyester/wool fabrics having different structural parameters and two types of polyester sewing threads were used. Three types of seam were made. The fabric samples were sewn using lockstitch with three different stitch densities. Obtained in this way seams were tested on the tensile machine. The influence of individual factors on the seam strength and its efficiency was assessed statistically using a multivariate variance analysis (ANOVA). Findings – The findings of this study revealed that the independent variable – stitch density affect significantly of the seam strength as well as its efficiency. Seam strength and seam efficiency values increase with the increase stitch density. Moreover, the variance analysis showed that a kind of fabric also is a statistically significant factor for the seam efficiency and its strength. Furthermore, in the case of seam efficiency it is also important to the stitch direction. However, the study did not show an impact of kind of thread and kind of seam on dependent variables: the seam strength and its efficiency. Research limitations/implications – Due to the fact that this paper focuses on the seams made only on wool/polyester fabrics with two the most popular weaves, involving only two sewing PES threads, the conclusions presented in this paper are valid only to this assortment and cannot be generalized. Originality/value – So far, it has not been taken research on the effect of seams with the different number of sewn layers on the seam strength and efficiency. This issue has been taken in this work.

Issue Relevance

Purpose – This paper aims to investigate the effects of minorities’ who experienced discrimination on perceptions of offensiveness tied to brand imagery that stereotypically depicts other minorities classified as out-group members. Design/methodology/approach – Study 1 utilizes factor analysis to develop dependent variables, and a path analysis to model relationships between the focal independent variable (IV) and dependent variable (DVs). Study 2 uses an experimental approach analyzing data with ANOVA and bootstrapping methodologies. Findings – Minorities who report experiencing more discrimination perceive more offensiveness tied to branding containing overt stereotypical depictions of out-groups. This effect is mediated through a perceived sympathy for the out-group. However, while some minorities perceive these branded logos as relatively more offensive, minorities, as a group, do not perceive these stereotyped logos as overly offensive. Research limitations/implications – Minorities not depicted in or alluded to in stereotypical imagery associated with a brand may be a valuable consumptive bloc that can be recruited to oppose such uses of stereotypes. This research highlights that any sympathy that these minorities report holding for depicted minority groups may be important to future targeted communications. Brand managers may need to aggressively defend the brand against negative attributions derived from non-depicted minorities’ felt sympathy. Depicted minorities fighting to remove stereotypical imagery in brands may be able to leverage non-depicted minorities’ expressed sympathy to form coalitions. Depicted minorities’ communications, however, may need to increase issue relevance to non-depicted minorities. Originality/value – This research explores how non-affected groups perceive stereotypes infused in branding. It demonstrates that, depending on past experiences, these individuals may defend against a perceived social threat targeted at a societal out-group.

Purpose The purpose of this study is to investigate online viewers’ preferences concerning the number and duration of video advertisements to watch during commercial breaks. The goal of the investigations was to assess whether online viewers preferred watching a fewer number of advertisements with longer durations or a greater number of advertisements with shorter durations. Design/methodology/approach Two studies used experimental research designs to assess viewers’ preferences regarding advertisements. These designs used two independent variables and one dependent variable. The first independent variable manipulated the type of choice options given to online viewers (e.g. one 60 s or two 30 s advertisements). The second independent variable manipulated when the choice was given to online viewers (i.e. at the beginning of the viewing experience or in the middle of the experience). The dependent variable measured viewers’ choices concerning their preferred advertisement option. Findings The results across both studies found that participants made choices that minimized total advertisement exposure time when possible. When minimizing total exposure time was not possible, participants made choices that minimized the number of exposures instead. Originality/value These investigations extend the literature on advertisement choice by examining online viewers’ preferences about the format of their advertising experience rather than the content of the persuasive messages themselves. In addition, these investigations provide value by investigating viewers’ responses to stimuli within realistic online simulations rather than abstract hypotheticals.

Purpose The purpose of this paper is to analyze the relationship between dissemination of research papers on Twitter and its influence on research impact. Design/methodology/approach Four types of journal Twitter accounts (journal, owner, publisher and no Twitter account) were defined to observe differences in the number of tweets and citations. In total, 4,176 articles from 350 journals were extracted from Plum Analytics. This altmetric provider tracks the number of tweets and citations for each paper. Student’s t-test for two-paired samples was used to detect significant differences between each group of journals. Regression analysis was performed to detect which variables may influence the getting of tweets and citations. Findings The results show that journals with their own Twitter account obtain more tweets (46 percent) and citations (34 percent) than journals without a Twitter account. Followers is the variable that attracts more tweets (ß=0.47) and citations (ß=0.28) but the effect is small and the fit is not good for tweets (R2=0.46) and insignificant for citations (R2=0.18). Originality/value This is the first study that tests the performance of research journals on Twitter according to their handles, observing how the dissemination of content in this microblogging network influences the citation of their papers.

Purpose This paper aims to investigate the relationship between corporate governance and auditors switching of listed companies on the Tehran Stock Exchange. Design/methodology/approach To achieve the objectives of this study, 12 hypotheses developed which and tests the relationship between corporate governance and selecting and switching auditors in Iran during 2008-20014 by selecting 116 listed companies on the Tehran Stock Exchange. To test the hypotheses, the cross-sectional time-series nature of research variables data, panel analysis is used. Also, to investigate the relationship between independent and dependent variables in each year, the logistic regression is used. Findings The results of the study indicate that there is a weak relationship between corporate governance auditors switching. Therefore, it could be concluded that there are some other effective factors on which selecting and switching auditors in studied companies are more dependent. Originality/value The current study is almost the first study which has been conducted in Iran, so the results of the study may be beneficial to the Iranian conditions as well as other developing countries.

Purpose The authors decided to study the causes of coercive management behavior (CMB) in universities because this area has been neglected in the past. There has been a lot of research into CMB in profit-oriented organizations, but it has been assumed that universities were unaffected. Design/methodology/approach The study was conducted at 10 universities, five from the private sector and five from the state sector out of the 100 accredited Ghanaian universities. The authors sent out 405 questionnaires and 371 were returned. Findings The results showed a strong relationship between specific causes and different dimensions of CMB. The authors said their analysis identified specific factors that “provide the seedbed for institutionalized bullying”. Originality/value The authors said the research provides the basis for designing policies for employees at any organization. A one-size-fits-all approach was not always appropriate, however, and their identification of the role of individual factors could help universities find their own solutions.

Purpose As a frequently observed business phenomenon, the use of product scarcity to improve a product’s market performance has received increasing attention from both academics and practitioners. The resulting literature has covered a wide variety of issues based on various theories, using different research methods, in a diverse range of settings. However, this diversity also makes it difficult to grasp the core themes and findings, and to see the outstanding knowledge gaps. This paper aims to review previous studies on the use of product scarcity in marketing and identifies new directions for future research. Design/methodology/approach A systematic review was conducted to identify and analyse 66 research papers published in business and management journals between 1970 and 2017. Findings The authors examined the underlying theories of scarcity-based marketing, and developed a conceptual framework that describes the key factors of product scarcity and how they influence both consumers and the market. They also highlighted some key achievements in modelling the processes involved in using product scarcity in marketing. Originality/value This analysis of the identified papers suggests that there are substantial gaps in our knowledge of this field, which opens up new paths for future research. For future research, the authors identified three directions aimed at: addressing the practical needs of firms in understanding product scarcity; guiding the implementation of scarcity-based strategies; and measuring, monitoring and predicting the level of product scarcity and its impacts during implementation.

Purpose Durability of textile materials under wet conditions has become very important in recent years. The water repellency performance of fabrics should be maintained in the seam areas. The purpose of this paper is to analyze the effect of water repellent agents and sewing threads on the seam and water repellency performance properties of woven fabrics. Design/methodology/approach 100 percent polyester woven fabrics were treated with three different water repellent finishing agents (silicone, fluorocarbons with 6 and 8 carbons) and then sewn with different sewing threads (unfinished/water repellent finished polyester/cotton corespun and polyamide filament). Afterwards, mechanical properties, seam performance and water repellency properties of these materials were measured. Findings The effect of finishing which was statistically significant on seam strength only in warp direction was significant on seam elongation and efficiency in both warp and weft directions. Seam strength, seam efficiency, seam slippage and seam pucker of fabrics sewn with polyamide threads were higher than others. The fluorocarbons applied to the fabrics gave higher water repellency values than silicones. In addition, as the chain length increased in fluorocarbons, water repellency performance increased. Sewing process reduced water resistance of fabrics; however, water repellent finish applied to the threads increased water resistance of fabrics. Originality/value As a result of the literature review, it was seen that water repellency property of a wear were studied in only seamless areas of fabrics. Originality of this study is that the water repellency properties are also analyzed in the seam areas of the fabrics and evaluated together with the seam performance characteristics.

Purpose Nowadays, there is a rapid growth in different sciences that has led to thousands of publications in the form of scientific research papers. The readers of these papers are generally the people that are involved in science (i.e. researchers, students, teachers and professors). On the other hand, practitioners rarely use these articles as a resource to learn and apply new methods. They prefer an easy to understand, step-by-step guide (i.e. cookbook) helping them skip over the difficult scientific terms and structures. Therefore, because of a shortage of tools in this space, it takes practitioners many years to use newly developed methods. Design/methodology/approach The purpose of this study is to review the literature on verified repositories and presents the necessity of method repositories. Findings This paper aims to introduce method repositories as new tools to bridge the gap between science and practice. Originality/value Method repositories presented in this paper act as an easy to understand guide for newly developed methods in specific fields.
