Purpose The intelligent identification of stains can quickly and accurately identify stains. At present, stains are identified subjectively by appearance, color, taste, feel, location, etc. Color is an important factor in identifying stains. K/S value is used to analyze the color of textile fabric, and it has additivity. The purpose of the study is to explore its application in stain recognition is of great significance to intelligent washing. Design/methodology/approach A certain method used to stain the textile, then the K/S value of the textile before and after the stain was analyzed and tested by the color difference instrument. The K/S curve of the stain was calculated by the addition of K/S, and then the stain was identified and distinguished. Findings The K/S value of the textile stained with stains could be deducted by the K/S value of the color difference meter. After deducting the base cloth, the K/S curve of the same stain is basically the same. Then the stain can be identified and analyzed. Research limitations/implications The K/S value can be used for stain analysis, but it needs to be analyzed and tested in the laboratory. Practical implications This study provides a simple method for stains identification. Originality/value In addition to common methods of stain identification, such as appearance, color, feel, smell, location, stain removal materials, breaking the substrate, IR, etc., K/S value can be used for stain analysis. Identifying stains and washing them in a targeted way to achieve a better washing effect could provide certain technical support for the development of smart washing and smart home appliances.

PurposeInnovative restaurant service designs impart food wellbeing to diners. This research comprehends customer aspirations and concerns in a restaurant-dining experience to develop a service design that enhances the dining experience using the design thinking approach and evaluates its efficiency using the Taguchi method of robust design.Design/methodology/approachThe sequential incidence technique defines diners' needs, which, followed by brainstorming sessions, helped create multiple service designs with important attributes. Prototype narration, as a scenario, acted as the stimulus for evaluators to respond to the WHO-5 wellbeing index scale. Scenario-based Taguchi experiment with nine foodservice attributes in two levels and the wellbeing score as the response variable helped identify levels of critical factors that develop better FWB.FindingsThe study identified the best combination of factors and their preferred levels to maximize FWB in a restaurant. Food serving hygiene, followed by information about cuisine specification, and food movement in the restaurant, were important to FWB. The experiment revealed that hygiene perceptions are critical to FWB, and service designs have a significant role in it. Consumers prefer detailed information about the ingredients and recipe of the food they eat; being confident that there will be no unacceptable ingredients added to the food inspires their FWB.Research limitations/implicationsTheoretically, this study contributes to the growing body of literature on design thinking and transformative service research, especially in the food industry.Practical implicationsThis paper details a simple method to identify and evaluate important factors that optimize FWB in a restaurant. The proposed methodology will help service designers and technology experts devise settings that consider customer priorities and contribute to their experience.Originality/valueThis study helps to understand the application of design thinking and the Taguchi approach for creating robust service designs that optimize FWB.

Purpose This paper aims to examine the role of religiosity on consumers’ forgiveness when celebrities get involved in transgression. The celebrity’s reaction and its impact on consumers’ forgiveness is tested as well. In addition, consumers’ attitudes towards the brand and celebrity as well as purchase intention for the endorsed brand are examined both before and after the transgression. Design/methodology/approach Data (n = 356) were collected through a self-administered online survey and analysed though structural equation modelling in AMOS 26. Findings The results show that consumers’ attitude towards celebrity, brand and purchase intention gets weaker once the celebrity gets into transgression. Consumers tend to forgive more if the celebrity apologises (vs denies) for the wrongdoing. The hypothesised relationship between attitude towards celebrity and purchase intention did not sustain after the transgression. In addition, consumers’ intrinsic religiosity strengthens the relationship between attitude towards the celebrity and purchase intention. Practical implications The findings of this research present valuable implications for brands practitioners. Brands should formulate actionable contingency plans to mitigate the negative ramifications of celebrity transgressions. Specifically, intrinsic religiosity and celebrity apologies should assist consumers in forgiving the transgression and negate the implications that could have arisen if the celebrity instead denied the transgressions. Originality/value This research extends the previous research by examining religiosity and forgiveness within the context of celebrity transgressions. To the best of the authors’ knowledge, this is one of the first few research studies to consider the role religiosity plays in consumers’ intention to forgive celebrity transgressions.

Purpose The purpose of this study was to explore if five subdimensions of perceived risk (financial, time, privacy, performance and psychological risks) negatively affects image. In addition, this study aims to investigate if image has a positive effect on intentions to use. Lastly, the purpose of this study was to examine the moderating effect of Coronavirus disease-2019 (COVID-19), before and after the outbreak, in the relationship between perceived risk and image. Design/methodology/approach Data were collected from 331 people before the COVID-19 outbreak and 343 people after the COVID-19 outbreak. To test hypotheses, this study used structural equation modeling. Findings Time, performance and psychological risks negatively affected image before the outbreak of COVID-19. Meanwhile, performance risks and psychological risks had a negative influence on image only after the outbreak of COVID-19. In addition, there was demonstrated to be a positive relationship between image and intentions to use, both before and after the COVID-19 outbreak. Finally, the outbreak of COVID-19 positively moderates the relationship between performance risk and image. Practical implications The current study provides the following practical implications. First, industry practitioners need to develop a performance guarantee system which enhances the quality assurance of drone food delivery services (DFDS). Second, live streaming or creative activities would help to visualize DFDS in a way that stresses the stable operation of these services. Originality/value The importance of contactless services has been emphasized ever since the beginning of the COVID-19 outbreak. However, there has been very little research on the future of contactless services after COVID-19. This study investigated the perceived risk from DFDS as a form of contactless service which has not been conducted before. The findings of this study will improve the understanding of the changes that have occurred in consumers’ perception of risk from DFDS during the COVID-19 pandemic.

Purpose The purpose of this paper is to describe the design and development of a final year undergraduate mathematics module designed to address professional skills development at a UK university, including via input to curriculum and assessment from employers, and to investigate student acquisition of skills from this module. Design/methodology/approach Literature on skills development in mathematics informs module design and development. Students optionally completed Likert-style competency questionnaires before and after the taught module content, and reflected on skills development via an end of module questionnaire. Data collection took place over three academic years. Findings Several key competencies exhibit median increases over the course of the module in each academic year, indicating a perceived skills development. Problem solving and presentation skills are particularly highlighted. Research limitations/implications Numbers of students were small, though the study is repeated with three different cohorts. Some students study mathematics jointly with another discipline and hence may have experience in skills development from the other subject. Practical implications This study indicates that innovations in teaching style and assessment in mathematics modules can enhance student confidence and competence with key professional skills. Originality/value Undergraduate modules in mathematics which have a focus on professional skills development are still fairly rare in UK universities. Often such modules do not embed the professional skills development activities with subject-specific technical tasks and projects as this module does. There are few formal studies of the effectiveness of this style of module, especially longitudinal studies covering several academic years.

A Current

Purpose Although there has been an increase in workplace studies on professional agency, few of these have examined the role of emotions in the enactment of agency at work. To date, professional agency has been mainly conceptualised as a goal-oriented, rational activity aimed at influencing a current state of affairs. Challenged by this, this study aims to elaborate the nature and quality of emotions and how they might be connected to the enactment of professional agency. Design/methodology/approach Data are collected in the context of a leadership coaching programme that aimed to promote the leaders’ professional agency over the course of a year. The participants (11 middle-management leaders working in university and hospital contexts) were interviewed before and after the programme, and the data were analysed using qualitative content analysis. Findings Findings showed that emotions played an important role in the leaders’ enactment of professional agency, as it pertained to their work and to their professional identity. The study suggests that enacting professional agency is by no means a matter of purely rational actions. Practical implications The study suggests that emotional agency can be learned and enhanced through group-based interventions reflecting on and processing one’s own professional roles and work. Originality/value As a theoretical conclusion, the study argues that professional agency should be reconceptualised in such a way as to acknowledge the importance of emotions (one’s own and those of one’s fellow workers) in practising agency within organisational contexts.

Interactional Effect

Purpose This paper aims to examine the effect of religiosity on the degree of auditor independence given the significance of symbolic gestures constructed by client economic conditions in different situations before and after considering the degree of auditors’ moral development. Design/methodology/approach The paper uses an experimental design based on running mixed factorial analysis of variance (SPANOVA) using mainly repeated measures GLM to test the interaction effects between (and within) variables on auditor independence. Findings The main findings indicate that there is a significant interactional effect between the degree of moral development and intrinsic religiosity on the degree of auditor independence, given the stimulating effect of the client’s economic gestures/conditions. Practical implications The Egyptian economy is growing and ensuring that auditor independence is paramount to sustaining the local, as well as foreign investors’ interest. Hence, this study is very important in highlighting factors that might lead to some impairment of auditors’ independence. Originality/value To the best of the authors’ knowledge, this study is the first to test the interactional effect between the religious orientation rather than religious affiliation and moral development on the degree of auditor independence, such a relationship has not been tested before in the literature. Additionally and most importantly, it uses statistical measurement through its experimental design, as there is a lack of studies in terms of auditor independence in Egypt. The existing literature follows the perceptional assessment rather than the real measurement of the degree of auditor independence.

Purpose The purpose of this paper is to understand how a company could improve public engagement on social media (SM) analysing the case of Alento, which is a human resources and consulting company located in Portugal. The company’s presence on Facebook was analysed by using the honeycomb model for SM functionality, by Kietzmann et al. (2011), as a theoretical framework. Design/methodology/approach The authors implemented some actions to change procedures on SM management. Monitoring five months of data, the authors could compare the SM engagement before and after changes on SM management. Then, a convenience sample of 205 useable questionnaires was collected. The population of the study comprised Portuguese Facebook users who liked the Alento Facebook Fan Page. An analysis of honeycomb dimensions was performed. Findings The engagement level on Alento’s SM was increased by changing procedures identified on survey. In five months, Alento’s number of followers was increased by just 4.5 per cent, interactions were increased by 35 per cent, views were more than twice (+122 per cent) and fans who clicked on Alento’s Facebook page’s links were increased by 146 per cent. Research limitations/implications There were also some limitations related to the sample, since the authors only obtained 205 responses. Therefore, the second suggestion for future investigations would be to conduct the survey on a larger number of people. This study just considers five months after changing procedures. A longer range of time could produce different results. Practical implications The most relevant contribution of the current study is the offer of some insights into the use of a simple tool such as the honeycomb model of Kietzmann et al. (2011) for the analysis of the social engagement from a firm’s perspective, regardless of their nature. Social implications The importance of SM to spread good content and to reduce media costs is reinforced in this study. Originality/value This study is innovative, as it identifies a need of change on SM management, proposes and implements new procedures, checking its results. SM marketing is a new wagon of study, and the problem of how to increase engagement on professional SM is on top priorities of the field.

Purpose The purpose of this paper is to evaluate a coordinated effort to improve the law enforcement response to non-fatal strangulation in the context of domestic violence. Design/methodology/approach The authors compare law enforcement identification and documentation of strangulation in domestic violence cases before and after the implementation of a strangulation-specific training program in one Central Florida County. Findings The results indicate preliminary support for the effectiveness of training law enforcement, suggesting that the response to strangulation can be improved with comprehensive law enforcement training. Practical implications An improved response by law enforcement may have the potential to increase offender accountability of non-fatal strangulation – a potentially deadly assault. Originality/value The study is the first to evaluate strangulation-specific training efforts of law enforcement. Results point to opportunities that can be taken to improve law enforcement’s response to non-fatal strangulation in domestic violence.

Purpose The purpose of this paper is to establish a suitable procedure for producing antimicrobial 100 per cent cotton textiles using zinc pyrithione. Zinc pyrithione being bacteriostatic in nature is eco-friendly and safe, both for manufacturer to apply and consumer to use. Design/methodology/approach After conducting laboratory trials, bulk trial has also been conducted, and efficacy of zinc pyrithione as bacteriostatic has been quantitatively determined. The durability of antimicrobial finish was also checked before and after repeated domestic laundry. Findings The findings indicated that it is possible to produce durable antimicrobial 100 per cent cotton textiles in bulk using zinc pyrithione. Research limitations/implications Any exporting textile processing mill can directly use the findings of this work and can produce antimicrobial textiles in their factory. Practical implications Any exporting textile mill can increase their export earnings by producing antimicrobial textiles. The antimicrobial textiles are in great demand in Asia-Pacific region and have already touched exports of US$497.4m in 2015 and is projected to reach US$1,076.1m by 2026. Social implications The textile user can get protection against pathogenic or odour-causing microorganisms using this hygiene finish in different end uses. Originality/value The work is original. Very few references are available on zinc pyrithione. First, laboratory studies were done, and bacteriostatic properties of zinc pyrithione were determined quantitatively followed by bulk trial.
