Practical Implications

Purpose The purpose of this paper is to examine the relationship between Amartya Sen’s notion of adaptation and his views on identity politics by focussing on the issue of slavery and, more specifically, on the example of the happy or contented slave. Design/methodology/approach The paper is text based. The methodological approach adopted is that of conceptual analysis, as is typical for work of this kind. Findings The paper concludes that the example of the happy or contented slave is indeed a fruitful one for those interested in exploring the relationship between Sen’s views on “the adaptation problem” and his views on identity politics, especially in relation to the subjection of women. Here Sen’s debt to the ideas of Mary Wollstonecraft and John Stuart Mill is particularly important. Research limitations/implications One implication of the argument of the paper is that there is a need to consider more carefully the differences that exist between the views of Wollstonecraft and Mill, so far as the example of the happy or contented slave is concerned. Practical implications One practical implication of the paper is that, hopefully, it establishes the continued relevance of the ideas of thinkers such as Wollstonecraft and Mill today, not least because of the influence that they have had on theoreticians such as Amartya Sen. Social implications The paper addresses issues which are of considerable social and political significance, especially for women in underdeveloped societies today. Originality/value The example of the happy or contented slave has not received much discussion in the literature on Sen, although Sen himself has suggested that the distinction between happiness and contentment is an important one, which does merit further discussion.

Purpose The purpose of this paper is to test the impact of a rule that affects tertiary students progressing from an introductory level finance course to intermediate level. The rule restricted students from progressing until they achieved a higher grade than just a “pass” mark. Design/methodology/approach Archival data were gathered from 11 semesters regarding student performance pre and post the rule being introduced. Findings Results show that the rule was associated with an increase in the chances of success at intermediate level for those students enrolled after the rule was introduced. Practical implications This paper’s main contribution regards the evidence that increasing prior learning at an introductory level has a positive follow-on effect for students learning at intermediate level. This has a practical implication for educators, as the rule has shown to increase the chance of success for knowledge development in the first year of studies. Originality/value The setting for this paper is unique and could potentially be replicated elsewhere. In 1980, Schaffer and Calkins called for an evaluation of the pre-requisites necessary for finance education at the tertiary level, and this paper answer this call stating that pre-requisites can contribute to the academic success of finance students.

Purpose The purpose of this paper is to report on research that uncovered myths about HIV and AIDS held by serodiscordant couples in Malawi, and the sources of these myths. The paper reflects on how the myths affect serodiscordant couples’ engagement with HIV and AIDS information. Design/methodology/approach Van Manen’s (1997) approach to analysis of phenomenological data was used to analyse data from in-depth interviews conducted in Malawi with 21 serodiscordant couples and three individuals who had separated from their partners because of serodiscordance. Findings Serodiscordant couples in Malawi believe and hold on to some inaccurate HIV and AIDS information that can be seen as “myths”. Some of these myths are perpetuated by official HIV and AIDS information when it is translated into the local languages. Other myths derive from social norms of the societies where the couples live. Practical implications The findings of this paper have practical implications for how HIV and AIDS information providers should engage with target audiences to understand the origins of the myths they hold. The findings also imply that some myths have technical, religious, moral and cultural bases which need to be addressed before challenging the myth itself. Originality/value Using real-life descriptions of experiences of HIV and AIDS information provided by serodiscordant couples, the authors reveal how myths can affect engagement with the information. The authors make recommendations on how to address myths in ways that contribute to a positive experience of HIV and AIDS information by serodiscordant couples.

PurposeThe author's purpose is to identify and analyze the progress of proposals and dissertations after mentor–mentee relationships rapidly transitioned to intensive online doctoral mentoring as a result of coronavirus 2019 (COVID-19).Design/methodology/approachAn exploratory pedagogic research design was implemented in 2020 to examine the COVID-19 Dyadic Online Mentoring Intervention, a four-month individualized approach to mentorship. A survey was completed by mentees in an educational leadership cohort that revealed the benefits and drawbacks of technology for learning within online doctoral mentoring contexts. Additional sources of data were published literature, mentor's notes, email exchanges, and scholarly enrichment products.FindingsData analysis yielded three themes: (1) mentoring strategies were utilized; (2) the pandemic unsettled reality and (3) personal professional development opportunities were evident. Although life challenges were exacerbated by the pandemic, the online doctoral mentoring intervention met dissertation-related needs and supported academic progress in a Doctorate in Education degree program.Practical implicationsTechnology-mediated mentoring during crises involves more than modality changes. Faculty mentors should not be solely responsible for mitigating program and dissertation disruption. Academic cultures must support the adoption of pedagogic innovations like high-quality online doctoral mentoring.Originality/valueOnline doctoral mentoring structures utilizing synchronous and asynchronous technologies can help mentees make academic progress in a crisis, not only in “normal” times.

Purpose The 2015 Modern Slavery Act focusses attention forms of modern slavery (human trafficking and forced labour), within the UK. The contemporaneous 2014 Care Act, identifies modern slavery as a new form of risk within adult social care, listing forms of abuse and vulnerability. However, it does not consider whether those providing care may themselves be vulnerable to forms of modern slavery. The paper aims to discuss these issues. Design/methodology/approach The authors describe the history of the development of modern slavery legislation in the UK, outline key provisions of the Care Act, illustrated with real-life cases. The analysis suggests that adult social care – characterised by informality, fragmentation and vulnerability – is one where instances of modern slavery may be more common than considered to date. Findings The data collected, though relatively modest, suggests that a thorough investigation should be undertaken into the possibility of modern slavery taking place within the realm of adult social care. Research limitations/implications Data have been collected through a snowball process, rolling out a survey to relevant groups of individual and organisations. A more rigorous investigation is required to examine the extent of modern slavery within adult social care. Practical implications The training of those responsible for the regulation/management of adult social care needs to ensure that they are fully equipped to understand the nature of modern slavery and how to identify its symptoms and victims. Social implications There is also a need for heightened awareness of those close to people being cared for that they may also identify the symptoms of modern slavery. Originality/value This area has not been explored to date.

PurposeThe purpose of this paper is to try and trace a new itinerary in the matter of the destabilization of financial institutions, i.e. the identification of a catalogue of measures that private law can offer in order to make sure that all unlawful initiatives resulting in the loss of credibility of financial markets and prejudice to the public at large do not escape the imposition of all possible liabilities.Design/methodology/approachThe matter here applied consists of the recourse to a number of experiences deriving from European legal systems that have tackled the phenomenon of unlawful attacks on the integrity of the financial markets through individual or organized acts. This comparative approach also benefits from the scrutiny of both legislation and judicial decisions: the latter are also looked at from the perspective of legal authors.FindingsThe most striking result of the research is that the instruments provided for by the private law remedies seem to be very efficient in the contrast of unlawful practices adversely affecting financial markets: the new spirit emerging from this survey is that it is imperative to set aside all contracts and agreements aimed at creating illicit ways to make profits and hide their origins.Practical implicationsThe practical implication should be to encourage all institutions with the task of checking the good functioning of financial markets to avail themselves of the tools here described to stabilize markets and deprive illegal contracts of their ill effects: it would be most desirable if such an approach were to be taken.Originality/valueThe novelty lies in the new approach described above (practical implications).

Purpose Marketers often assume that functional, hedonic and socially conspicuous utilities in choosing a brand differ for men and women, thus different marketing strategies are required for each gender. To date, most of the research studies have used self-reported measures when shopping in general or in regard to a single product. The purpose of this research is to examine this question using two different contexts of brand choice: single choice evaluation (SCE) and brand selection context (BSC). This assessment will clarify whether male and female utilities when choosing a brand are indeed inherent and consistent. Design/methodology/approach Data were collected using surveys in three studies (N = 923). Conjoint analysis and ICLV (integrated choice and latent variables) models were examined. Findings BSC analysis that more closely mimics real-life contexts revealed that the consideration of these utilities is generally similar for men and women, while the SCE analysis showed significant gender differences. Practical implications In the context of choosing between brands, stereotypical gender targeting may be ineffective and might not be the best allocation of resources for marketers. Social implications Gender stereotypes in advertising seem to reconstruct differences that are not significant in a realistic brand selection context. Originality/value The context of choice was found to be a condition boundary for gender differences in brand choice considerations. Gender differences are not evolutionary or inherent.

Purpose The purpose of this paper is to detail the design and prototyping of a smart automation solution for de-strapping plastic bonding straps on shipping pallets, which are loaded with multiple containers secured by a top-cover as they move on a conveyor belt. Design/methodology/approach The adopted design methodology to have the system perform its function entails using the least number of sensors and actuators to arrive at an economic solution from a system design viewpoint. Two prototypes of the robotic structure are designed and built, one in a research laboratory and another in an industrial plant, to perform localized cutting and grabbing of the plastic straps, with the help of a custom-designed passive localizing structure. The proposed structure is engineered to locate the plastic straps using one degree of freedom (DOF) only. An additional strap removal mechanism is designed to collect the straps and prevent them from interfering with the conveyor. Findings The functionality of the system is validated by performing full-process tests on the developed prototypes in a laboratory setting and under real-life operating conditions at BMW Group facilities. Testing showed that the proposed localization system meets the specified requirements and can be generalized and adapted to other industrial processes with similar requirements. Practical implications The proposed automated system for de-strapping pallets can be deployed in assembly or manufacturing facilities that receive parts in standard shipping pallets that are used worldwide. Originality/value To the best of the authors’ knowledge, this is the first mechanically smart system that is used for the automated removal of straps from shipping pallets used in assembly facilities. The two main novelties of the proposed design are the robustness of the strap localization without the need for computer vision and a large number of DOF, and the critical placement and choice of the cutting and gripping tools to minimize the number of needed actuators.

Purpose The purpose of this paper is to investigate the “organic” phenomenon within a sample of companies and try to depict the main business model (BM) features and profiles. Design/methodology/approach The methodology used for the current research is twofold: first, a literature analysis has been conducted in order to highlight the gap in the existing literature. Then, the different BM profiles were investigated through a survey questionnaire conducted among a sample of Italian organic companies and organic districts. The evidence from the literature review supported the researchers during the empirical phase. Findings From the literature review, it emerged that studies on the BMs of organic companies and organic districts need a deep analysis and a literature gap on this topic has emerged. From the BM point of view, clustering sheds light on proactive companies, which are characterized by a higher level of education among entrepreneurs, greater investments in the business and the sale of products within and outside of the domestic market. Research limitations/implications Limitations include the number of answers collected through surveys and the focus on a single country. Practical implications The main practical implication focuses on the regulatory bodies that should better understand the BMs characteristics implementing adequate policies for the development of organic companies and districts. Originality/value The main practical implication focuses on the regulatory bodies that should better understand the BM characteristics and implement adequate policies for the development of organic companies and districts.
