Purpose The conversion of fabric into a garment involves many interactions such as the selection of suitable sewing thread, optimization of sewing parameters, ease of conversion of fabric into the garment and actual performance of the sewn fabric during wear of the garment. The adjustment of all sewing parameters is necessary to ensure quality. The purpose of this paper is to define the parameters that affect seam quality comprehensively. Design/methodology/approach This study primarily focuses on the studies dealing with the effect of various parameters on-seam quality in detail. A systematic literature review was conducted. Findings The interactions between parameters may lead to different results than the effect of a single parameter. In addition, changing some parameters may have a positive effect on one element of seam quality while having a negative effect on another. For this reason, it is very important to properly select the parameters according to the specific end use of the garment products and also to consider the interactions. Originality/value The knowledge of various factors that affect seam quality will be helpful for manufacturers to improve production performance and to be able to produce high-quality seam.

Purpose This research aims to analyze the effects of religiosity on the decision to participate in a boycott and the effect of a boycott on attitudes toward the boycotted brand. It also aims to measure the moderating effect of brand loyalty on the different models the authors discuss. Design/methodology/approach An experiment involving 165 Tunisian individuals during a call for a boycott of products of the Coca-Cola Company, which supports the Israeli army against Palestine, was conducted. Data analyses were conducted via two principal stages using SPSS 20.0 and Smart PLS 2.0. Findings The findings show that degree of religiosity was one of the antecedents of decision to participate in a boycott, and this decision has a negative effect on the attitude toward the brand being boycotted. The paper also has been able to show that brand loyalty moderates the relation of the present model. It diminishes the effect of religiosity on boycotting. Research limitations/implications Among the limits of the study is the fact that the authors relied on the investigation of only one product/brand (namely, Coca-Cola). In addition, the samples subjected to inquiry by the authors were chosen for their convenience. Practical implications Besides, the presentation of boycotted products in stores has a negative effect on the sales of the surrounding “non-boycotted” products (Friedman, 1999a). The authors note here that marketers can derive huge benefits from the exploration of boycott, for many reasons. The company must insist on the satisfaction and trust of their consumers, which are the bases of the loyalty. They must define the marketing strategy to increase the loyalty. This will diminish the effect of religiosity on the decision to participate in the boycott. Social implications The results allow us to assert that the decision to participate in a boycott has a negative effect on the attitude of the consumer and on the brand to be boycotted. Investigating the moderating effect of loyalty on the relation between religiosity and the decision to participate in a boycott is very interesting. Originality/value This research has shown that religiosity has a positive effect on boycotting. Also, it was found that a boycott has a negative effect on attitudes toward the boycotted brand. Therefore, brand loyalty moderates negatively the effect of religiosity on the decision to participate in the boycott and moderates the effect of the boycott on brand attitude.

Purpose By its high fluidity, great deformability and rheological stability, the self-compacting mortar (SCM) is capable of ensuring the ability to be easily implemented without vibration. However, its formulation requires a large volume of fine materials with a high dosage of cement, which is necessary to ensure adequate workability and mechanical strengths, which is necessary to allow its flow. Current environmental considerations encourage reducing the production of cement, it is essential to use additions to replace the cement, because of their great availability and their moderate price. On another side, their use contributes to an economic sort to solve the problems related to the environment. Design/methodology/approach The formulations and characteristics of SCM made with two types of mineralogical sources (silica and limestone) were investigated. Different materials were used separately and in binary combinations; silica river sand (SRS), limestone quarry sand (LQS), silica fillers (SF) and limestone fillers (LF). The formulation starts with the self-compacting pastes (SCPs) then the SCMs at the SRS and the LQS whose the cement is partially replaced by volume contents of SF and LF with 15%, 30% and 45%. Findings The results obtained prove that the incorporation of LQS instead of SRS has a negative effect on the fluidity and deformability and a positive effect on the mechanical strengths of SCM. In addition, the incorporation of the SF and LF reduces the need for water and the saturation dose of superplasticizer in the pastes. Thus, the addition of the SF and LF in specific voluminal contents (15% SF and 30% LF) in the binder can have a beneficial effect on the parameters of the workability and the mechanical strengths of SCM. These results are very interesting to aspects such as technological, economic and environmental. Originality/value Influence of the different type of sands and fillers in improvements the properties of SCM made from various mineralogical sources.

Purpose Empirical research presents conflicting findings with regards to the effectiveness of referral reward programs (RRPs) and supports two alternative and conflicting views on the effectiveness of incentivizing recommendations. They are, first, a positive effect via perceived attractiveness of the incentive, and second, a negative effect via metaperception of the recommendation. The purpose of this paper is to examine these two opposing psychological mechanisms to reconcile the conflicting findings. Design/methodology/approach The authors conducted three experiments. Study 1 tests the base model. Studies 2 and 3 add moderators to test whether each mediating variable operates exclusively on its intended relationship. Findings Incentive size enhanced the attractiveness of an incentive, but reduced the metaperception favorability of the recommendation. These two opposing mechanisms operated in parallel, independently and fully mediated the effects of incentive size to likelihood of making a recommendation. Thus, the net impact of incentives on recommendation behavior depended on the relative strengths of these two opposing forces. Practical implications The study recommends managers to design RRPs with incentives that recommenders perceive as highly useful (i.e. to increase attractiveness) but have a low face value (i.e. to reduce metaperception concerns) and to target RRPs to strong rather than weak ties. Originality/value Our work offers an integrated theoretical account of consumers’ responses to incentivized recommendations and provides managerially relevant guidelines for the design of effective RRPs.

Purpose Strategic transformations are likely necessary for all organizations at some point in their existence, but the role of external stakeholders in committing resources to support transformations has been largely overlooked. This paper aims to begin to fill this gap by developing a theoretical model detailing which factors increase the likelihood that financial stakeholders will commit resources to strategic transformation. Design/methodology/approach Neo-institutional and stakeholder theories are applied to the strategic transformation phenomenon to develop six propositions regarding financial stakeholders’ resource commitment to strategic transformation. Findings Moral legitimacy, pragmatic legitimacy and unfamiliarity with the firm directly affect the likelihood that financial stakeholders will commit resources to strategic transformation. Cognitive legitimacy or familiarity amplifies the positive effect of pragmatic legitimacy on resource commitment, and pragmatic legitimacy lessens the negative effect of unfamiliarity with the firm on resource commitment. Originality value This paper lays out a clear conceptual model of the antecedents of financial stakeholders’ resource commitment to strategic transformation, aiding practitioners in securing critical stakeholder support and filling an important gap in strategic transformation/stakeholder literature.

Purpose – The purpose of this paper is to examine the causal relationships between inflation, output growth and their uncertainties in Malaysia. Design/methodology/approach – The modeling approach allows for structural breaks to avoid the masking of specific impacts. Findings – Based on the asymmetric Generalized Autoregressive Conditional Heteroskedasticity model, the paper found strong evidence favoring a positive effect of a change in the inflation uncertainty as predicted by the Friedman-Ball hypothesis. In addition, inflation (inflation uncertainty) has direct (indirect) negative effect on the output growth. The results are consistent with the Taylor effect – increases in inflation uncertainty decreases output uncertainty. The analysis also reveals that economic uncertainty lowers the growth rate of output, complying with Bernanke's idea. Originality/value – The present study suggests that extra efforts are required to locate the breaks in the variance in order to draw concrete evidence on link between economic uncertainty and macroeconomic performance.

Purpose – This paper investigates the determinants of credit card use and misuse by student and young professionals. Critical to the research is the impact of materialism and knowledge on selection of the appropriate credit card. Design/methodology/approach – This study uses survey research and partial least squares to investigate credit card behaviors of students versus young professionals. Findings – In a comparative study of young professionals and students, it was found that consumer knowledge, as expected, leads to better consumer selection of credit cards. Materialism was also found to increase the motivation for more optimal consumer outcomes. For more experienced consumers, such as young professionals, it was found that despite them being more knowledgeable, they were more likely to select a credit card based on impulse. Originality/value – This paper examines how materialism may in fact encourage some consumers to make better decisions because they are more motivated to develop better knowledge. It also shows how better credit card selection may inhibit impulse purchasing.

Purpose The purpose of this study is to investigate the effects of the activity-based workspace (ABW) on employee belonging. Place attachment theory (PAT) is used as a proxy to understand and measure the belongingness of employees to their physical workplaces. Design/methodology/approach A case study of a bank’s newly retrofitted ABW office is conducted, providing fresh perspectives on the effect of ABW on employee belonging. A questionnaire survey was used to understand employee belongingness. Surveys are conducted with employees of the bank (n = 100) who experienced the transition from the conventional open-plan office with designated seats to an ABW, to understand and compare the change in employee belonging after the transition, by studying the level of belonging achieved in the space before and after. Findings The results showed that there was a positive sense of belongingness amongst employees working in the ABW space, as per the PAT framework and an increased sense of belongingness compared with the previous conventional open-plan office. However, ABWs were found to also have a negative effect on employees’ sense of control and security. Originality/value Maslow’s hierarchy of needs indicates that a feeling of belonging is fundamental to humans. The need for belonging is also applicable in the workplaces of today’s progressive corporate organisations, where there is increased pressure and incentive to appeal to and retain talent. This research was conducted in response to the huge growth in interest in activity-based working across the corporate real estate community. As there has been no prior research done in the area of the emotional need for belongingness in ABW.

Purpose This study aims to investigate the effect of teaching style and academic enthusiasm of Iraqi accounting and auditing students on their stress, aggression and anxiety. Design/methodology/approach The statistical population in this study consists of two parts. The first is the Iraqi accounting and auditing students in Iran and the second is the Iraqi accounting and auditing students in Iraq. By available non-probability sampling method, 62 people (Iraqi students in Iran) and 102 (Iraqi students in Iraq) were selected as samples. In this research, a questionnaire was used to collect information. The validity of the questionnaire’s structure was confirmed by confirmatory factor analysis. Also, Cronbach’s alpha coefficients in this study indicating the measurement tool’s reliability. In this research, structural equation modeling has been used to analyze and test the hypotheses. The primary criteria for determining the coefficient and evaluating the path coefficients were used to evaluate the structural model. Findings Findings indicate that in Iraqi students in Iraq and Iraqi students in Iran, teaching style negatively affects stress, aggression and accounting and auditing students’ anxiety. Also, in the group of Iraqi students in Iraq and the group of Iraqi students in Iran, the eagerness to study has a significant negative effect on accounting and auditing students’ stress and anxiety. In contrast, the effect of the desire to study accounting and auditing students’ aggression was confirmed only in Iraqi students in Iraq. Originality/value As the accounting and auditing professions are among the most stressful occupations that increase the characteristics of aggression and anxiety in the employees of that profession, the results of leading research can show that the stress, anxiety and aggression of accounting and auditing students how to reduce through training so that their stress, anxiety and aggression do not appear in the workplace and the reports of accountants and auditors are not affected.

PurposeThe purpose of this paper is to demonstrate a “maintenance pathway” for ensuring a low false negative rate in closing investigations unlikely to lead to a clearance (detection).Design/methodology/approachA randomised controlled experiment testing solvability factors for non-domestic cases of minor violence.FindingsA random selection of 788 cases, of which 428 would have been screened out, were sent forward for full investigation. The number of cases actually detected was 22. A total of 19 of these were from the 360 recommended for allocation. This represents an improvement of accuracy over the original tests of the model three years earlier.Research limitations/implicationsThis study shows how the safety of an investigative triage tool can be checked on a continuous basis for accuracy in predicting the cases unlikely to be solved if referred for full investigations.Practical implicationsThis safety check pathway means that many more cases can be closed after preliminary investigations, thus saving substantial time for working on cases more likely to yield a detection if sufficient time is put into the cases.Social implicationsMore offenders may be caught and brought to justice by using triage with a safety backstop for accurate forecasting.Originality/valueThis is the first published study of a maintenance pathway based on a random selection of cases that would otherwise not have been investigated. If widely applied, it could yield far greater time for police to pursue high-harm, serious violence.
