Purpose The uncertainty of remanufacturing parts is a key factor affecting the quality of remanufactured products. Therefore, the purpose of this paper is to measure the uncertainty of remanufactured parts and study the coupling mechanism of reassembly quality. Design/methodology/approach First, uncertainty of remanufactured parts is analyzed, and the uncertainty measure model for remanufacturing parts based on entropy is constructed. Second, the nonlinear mapping model between the uncertainty and reassembly quality were studied using Gauss-Newton iterative method to reveal the coupling mechanism between uncertainty of remanufacturing parts and reassembly quality. Finally, the model is verified in the reassembly process of remanufacturing cylinder head. Findings The method can guide reassembly operations to improve the reassembly quality with uncertainty of remanufactured parts. Originality/value This study provides practical implications by developing a multivariate nonlinear mapping model for reassembly quality based on entropy to determine the uncertainty factors that affect the reassembly quality significantly and then correct the reassembly operation to better optimize the allocation of remanufacturing production resources. The study also theoretically contributes to reveal the coupling mechanism of reassembly quality with the uncertainty of remanufactured parts.

PurposeIntegrated healthcare is a central tenant of the NHS Long Term Plan (NHS, 2019). NICE in 2019 published guidelines; advising the integration of multidisciplinary professionals which may lead to an improvement in conservative treatment methods of pelvic organ prolapse. Therefore, current literature on the conservative treatments for pelvic organ prolapse needs to be reviewed to ascertain if an integrated approach would improve the symptoms and quality of life for women.Design/methodology/approachA systematic review of the literature between 2013 and 2018 was implemented. Papers included were written in English, peer-reviewed and consisted of treatments of pelvic organ prolapse in women. Papers containing surgical interventions, postpartum participants, reviews, evaluations, guidelines, follow-up studies, focusing on cost effectiveness, sexual function were excluded.FindingsSeven studies in total were included, and two overarching themes were identified: quality of life after treatment and the effect of conservative treatment on pelvic organ prolapse symptoms. The literature suggested that integrating care had a more positive outcome on pelvic organ symptoms and quality of life.Research limitations/implicationsTo develop a robust enhanced model of care for conservative treatment of pelvic organ prolapse through more mixed method or qualitative research, that incorporates integrative treatment methods with collaboration from multidisciplinary professionals.Practical implicationsThe practical implications of integrating the conservative management of pelvic organ prolapse is the communication between the multidisciplinary team must be exceptional to ensure everyone understands and agrees the treatment that is being provided to patient. Also, effective teamwork is important to ensure the patient receives the best care with input from the correct disciplines. The multi-professional team will need to have regular meetings to discuss and implement care plans for patients that might prove difficult to schedule due to differing commitments and priorities. This must be overcome to insure a successful and effective integrated approach to pelvic organ prolapse is delivered.Social implicationsThe social implications of integrating the professional approach to women's care of pelvic organ prolapse involves reducing the severity of the symptoms therefore, increasing the quality of life. This may result in the reduction of surgical intervention due to the patient being satisfied with the conservative management. Through integrating the management of the prolapse the patient will receive an accessible individualised care plan pathway that focuses on treating or reducing the impact of the symptoms that are bothersome to the patient whilst managing patient expectations. Patients will also, be reassured by the number of multi-disciplinary professionals involved in their care.Originality/valueGlobal integration of conservative treatments and multidisciplinary-professionals specialising in pelvic organ prolapse and pelvic floor dysfunction is needed.

Purpose – The purpose of this paper is to map the field of sociological animal studies through some examples of critical and mainstream approaches and considers their relation to advocacy. It makes the argument that while all these initiatives have made important contributions to the project of “animalising sociology” and suggest a need for change in species relations, the link between analysis and political strategy is uncertain. Design/methodology/approach – The paper develops its argument by using secondary sources, reviewing sociological positions and offering illustrations of possible interventions. Findings – Sociological interventions in the field of animal studies have been informed by critical perspectives, such as feminism and Marxism, or taken less critical routes deploying actor-network theory and symbolic interactionism. Whilst those working in critical traditions may appear to have a more certain political agenda, an analysis of “how things are” does not always lead to a clear position on “what is to be done” in terms of social movement agendas or policy intervention. In addition, concepts deployed in advocacy such as “liberation”, “quality of life” or “care” are problematic when applied beyond the human. Despite this, there are possibilities for coalition and solidarity around certain claims for change. Research limitations/implications – If the central argument of the paper were taken seriously by general sociologists, then sociology may be more open to “animal studies”. In implications for exisitng sociological animal studies scholarship is to trouble some of the certainties around advocacy. Practical implications – If the central argument of the paper were taken seriously by advocacy groups, then the hiatus between “welfarism” and “liberation” might be overcome. Originality/value – There have been recent attempts to map the field of scholarship in animal studies, but surprisingly little consideration of how different emergent positions inform questions of advocacy and the possibilities for political intervention.

Purpose This paper aims to present a model of shareholders’ willingness to exert effort to reduce the likelihood of bank distress and the implications of the presence of contingent convertible (CoCo) bonds in the liabilities structure of a bank. Design/methodology/approach This study presents a basic model about the moral hazard surrounding shareholders willingness to exert effort that increases the likelihood of a bank’s success. This study uses a one-shot game and so do not capture the effects of repeated interactions. Findings Consistent with the existing literature, this study shows that the direction of the wealth transfer at the conversion of CoCo bonds determines their impact on shareholder risk-taking incentives. This study also finds that “anytime” CoCos (CoCo bonds trigger-able anytime at the discretion of managers) have a minor advantage over regular CoCo bonds, and that quality of capital requirements can reduce the risk-taking incentives of shareholders. Practical implications This study argues that shareholders can also use manager-specific CoCo bonds to reduce the riskiness of the bank activities. The issuance of such bonds can increase the resilience of individual banks and the whole banking system. Regulators can use restrictions on conversion rates and/or requirements on the quality of capital to address the impact of CoCo bonds issuance on risk-taking incentives. Originality/value To model the risk-taking incentives, authors generally modify the asset processes to introduce components that reflect asymmetric information between CoCo holders and shareholders and/or managers. This paper follows a simpler method similar to that of Holmström and Tirole (1998).

Purpose It has recently become more acknowledged that there is a quality of “messiness” to the qualitative research process. The purpose of this paper is to introduce the fieldpath approach—a hermeneutically inspired framework—to account for the non-linearity, uncertainty and ambiguity of the research process. Design/methodology/approach This conceptual paper reviews how the scope of hermeneutics has been partly misunderstood. The paper discusses how the scope of hermeneutics has lately been expanded by works such as Günter Figal’s (2010) Objectivity: The Hermeneutical and Philosophy. Findings The fieldpath approach proposes that a heightened relation to materiality enables the messiness of the process to be preserved, while at the same time offering a way to find one’s footing in the midst of ontologically incomplete phenomena that are still—in a processual fashion—forming and becoming. Research limitations/implications This is a conceptual paper. In addition to the research mentioned here, more studies would be needed to legitimise, test and refine the approach. Practical implications Objectivity provides an additional criterion for researchers to lean on when facing the non-linearity and unexpected turns inherent in the qualitative research process. Social implications The stress on materiality involves an ethical dimension. Post-human ethics are concerned with the future environmental consequences and sustainability of the material world. The way that matter matters in our methodologies is of primary importance. Originality/value First, the paper emphasises that hermeneutics, contrary to the common perception, does offer criteria for evaluating between interpretations. Second, it introduces the notion of hermeneutic objectivity, which stresses the importance of materiality for interpretations. Third, it introduces the fieldpath approach, which, based on the previous criterion of hermeneutic objectivity, allows for the messiness of the research process, while also preserving a tight grip on the hermeneutic imperative of “understanding in a new way”.

Purpose – The aim of this paper is to determine the sensory quality of food in restaurants by professional food evaluators and to research the impact of education, age and number of employees on the quality of food. Design/methodology/approach – In the first phase five trained food tasters evaluated the sensory quality of food. In the second phase, the analysis of the structure of employees was done by establishing their level of education, age and number of employees. In the third phase the regression and correlation analysis was done with the aim to establish the impact of the level of education, age and number of employees on the sensory quality of food. Findings – The sensory evaluation has shown that the evaluated food is of moderate quality. Correlation matrix has shown that the education level of employees has a high impact on the sensory quality of food. There is a correlation between the number of employees, their age and their education. Practical implications – Obtained results are the indicators of the quality of food in restaurants in the region and they can serve for the improvement of quality. They have shown that education and staff training can contribute to a better quality of food. Established methodology can also contribute to the practical evaluation of quality. Originality/value – This paper is reflected on the specific application of methodology of the sensory analysis of food in restaurants. The paper pointed to the impact of employees on the sensory quality of food by statistical methods. Statistical results which point to the great impact of the level of education of employees on the sensory quality of food in restaurants are particularly valuable.

Purpose Hypermarkets face a very competitive environment, as their rivals also include traditional markets, convenient stores and supermarkets. In addition to offering innovative services, hypermarket managers must also pay attention to customer shopping patterns and behaviors in order to gain market share. The purpose of this paper is to posit that there will be significant differences between male and female hypermarket customers in terms of both shopping time and categories of goods purchased. Design/methodology/approach To investigate actual shopping behaviors, this study observed customers in hypermarkets and recorded how long they spent shopping and what they purchased. Findings The results of this study implied that gender is a key factor that affects both shopping time and the goods purchased in Taiwanese hypermarkets. The empirical findings also indicated that customers favor certain goods categories. Practical implications The results of this study provide details of the differences between male and female hypermarket customers, with which managers can use to develop better marketing strategies. Originality/value The purpose of this study is to show hypermarket retailers how gender differences affect customer behavior in this context. It also presents a consumer product categories list for hypermarkets, and this can be used as a reference for follow-up studies.

Purpose The purpose of this paper is to study the changing relationship between auditing and evaluation. Over the past several years, supreme auditing institutions (SAIs) in a number of advanced democracies have evolved from conventional auditing institutions to becoming increasingly concerned with assisting policy change and administrative reform in the public sector; tasks that are traditionally associated with evaluation. The paper discusses the potential consequences of this development for the SAIs themselves as well as for the audited and reforming institutions and for policy-making. Design/methodology/approach The paper uses qualitative method and draws on the extensive literature on auditing and evaluation. The analysis has also benefitted from the authors’ recent comparative research on SAIs. Findings The findings, summarized in six points, are that the growth of auditing in areas previously assigned to evaluators, has led to a shortened time perspective; stronger emphasis on the administration of policies; increased focus on efficiency of the audited entity; greater independence from the evaluated organizations; a shift in receiver of information toward the legislature and/or the public; and improved communication. Practical implications Evaluation as a professional and scholarly field has developed theories and advanced methods to assess the effectiveness of public programs. The growth of auditing may thus change the focus and quality of policy evaluation. Originality/value The paper speaks to both scholars and practitioners. To the best of the knowledge a similar analysis has not been done before.

PurposeThis study contributes to the leadership literature by examining how and when despotic leadership jeopardizes employees' performance. Specifically, we examine whether employees' job performance could be harmed by despotic supervision through employees' work withdrawal behaviour. Moreover, we investigate whether the quality of work-life (QWL) helps in toning down the harmful effects of despotic supervision on work withdrawal.Design/methodology/approachWe used a multi-wave research design with data collected from 195 employees and their supervisors working in Pakistan's manufacturing sector. At time 1, we measured the independent variable (i.e. despotic leadership) and moderator (QWL), whereas, at time-2, the mediator (work withdrawal) was tapped by the same respondent with a time interval of three weeks between them. At time 3, the outcome (supervisor-rated job performance) was assessed directly by the supervisors.FindingsThe results support the mediating effect between despotic leadership and employees' performance through an enhanced level of work withdrawal behaviour. The effect of despotic leadership on job performance via work withdrawal behaviour was found to be weaker among employees with a higher level of QWL.Practical implicationsFor individuals, QWL serves as an enhancement of personal resources to deal with despotic leaders at the workplace; for organizations, our study results alert managers and leaders at the workplace to address employees' need for QWL as this positive resource may discourage work withdrawal behaviour and stimulate employees to perform well in their jobs despite facing despotic supervision.Originality/valueThis study contributes to the leadership literature by introducing work withdrawal as an underlying mechanism to explain the despotic leadership – job performance relationship. Further, we examined how the harmful effects of despotic leadership can be toned down through the moderating variable of QWL thus having practical implications for both employers and employees.

PurposeThis paper furthers research into the potential contribution of pollutant databases for corporate accountability. We evaluate the quality of corporate and government mercury reporting via the Australian National Pollutant Inventory (NPI), which underpins Australia's reporting under the Minamata Convention, a global agreement to reduce mercury pollution.Design/methodology/approachThe qualitative characteristics of accounting information are used as a theoretical frame to analyse ten interviews with thirteen interviewees as well as 54 submissions to the 2018 governmental enquiry into the NPI.FindingsWhile Australian mercury accounting using the NPI is likely sufficient to meet the expected Minamata reporting requirements (especially in comparison to developing countries), we find significant limitations in relation to comparability, accuracy, timeliness and completeness. These limitations primarily relate to government (as opposed to industry) deficiencies, caused by insufficient funding. The findings suggest that multiple factors are required to realise the potential of pollutant databases for corporate accountability, including appropriate rules, ideological commitment and resourcingPractical implicationsThe provision of additional funding would enable the NPI to be considerably improved (for mercury as well as other pollutants), particularly in relation to the measurement and reporting of emissions from diffuse sources.Originality/valueWhilst there have been prior reviews of the NPI, none have focused on mercury, whilst conversely prior studies which have discussed mercury information have not focused on the NPI. In addition, no prior NPI studies have utilised interviews nor have engaged directly with NPI regulators. There has been little prior engagement with pollutant databases in social and environmental accounting (SEA) research.

Purpose Guided by the resource-based theory, the purpose of this study was to predict the role of football talent in the Federation Internationale de Football Association (FIFA) rankings of the men’s national football teams in the Copa America zone. Design/methodology/approach The study used archival data of Copa American national football teams. The dependent variable was FIFA rankings, and the independent variables were football talent (measured by the stocks of amateur footballers, professional footballers and football officials). Statistical analysis was performed using Kendall tau statistic and binary logistic regression. Findings The binary logistic regression results indicated that FIFA rankings were statistically and significantly associated with the stock of football officials and professional footballers – but not amateur footballers. The predictive model explained 80 per cent of the variance. Research limitations/implications The study focused exclusively on the stock of football talent in each nation, and not alternative determinants of national football team competitiveness as economic power and quality of professional football leagues, among others. Practical implications The stocks of professional footballers and football officials are valuable sources of competitive advantage (CA) in national football team rankings. Originality/value The study highlighted the uniqueness and distinctiveness of a nation possessing large stocks of professional footballers which can boost the CA and rankings of Copa American national football teams.
