Purpose The paper aims to focus on the individual contribution of water to the lubrication regimes in articular joints because understanding of these regimes is crucial not only for the treatment of diseases like osteoarthritis but also for the development of new implants to have a longer service cycle. Design/methodology/approach Cartilage specimen and the synovial fluid were both isolated from bovine knee joints that are enclosed by a synovial membrane under sterile conditions of a biosafety Level 2 (BSL2) cabinet. Subchondral bone was removed from the cartilage because it not only creates a stable base to place the specimen on the holder, but it also acts as a primary shock absorber protecting the overlaying cartilage under high-impact loads. A specimen holder specially designed for tests and was attached to the linear oscillation (SRV) test machine. The SRV test machine provides a reciprocating sliding motion between the cartilage samples that are submerged into the selected biological media. The entire system can be mounted on the BSL2 cabinet, sealed with the convoluted gaiter and transported to the SRV machine with a specifically designed handle for the entire system. The process ensures sterile conditions for tests on biological samples that are highly sensitive to the environmental conditions. Findings A remarkably low coefficient of friction value for distilled water constitutes more evidence to support the assumption of the impact of water in the friction behaviour of the cartilage-against-cartilage contact. As the fluid in articular cartilage (AC) effectively serves as a synovial fluid reserve and 70-80 per cent of its composition is distilled water, it can be stated that the tribotest system mimics the natural working conditions of an actual knee joint adequately. Research limitations/implications Time and limited availability of the animal-driven samples led to a focus on certain parameters mentioned in the approach. A planned scan of parameter matrix, such as variation of load and speed, would allow deeper knowledge on the lubrication regimes. Practical implications Study of relevant tribological contact in human joints might give ideas on new designs for artificial joints. Social implications Understanding of lubrication regimes is crucial not only for the treatment of diseases like osteoarthritis but also for the development of new implants to adapt motion of related joint. Originality/value Exclusion of water and application as the primary lubricant in the test system brings a new perspective to joint lubrication.

Purpose – This paper aims to add to the understanding of knowledge sharing in online communities through an investigation of the relationship between individual participant’s motivations and management in open source software (OSS) communities. Drawing on a review of literature concerning knowledge sharing in organisations, the factors that motivate participants to share their knowledge in OSS communities, and the management of such communities, it is hypothesised that the quality of management influences the extent to which the motivations of members actually result in knowledge sharing. Design/methodology/approach – To test the hypothesis, quantitative data were collected through an online questionnaire survey of OSS web developers with the aim of gathering respondents’ opinions concerning knowledge sharing, motivations to share knowledge and satisfaction with the management of OSS projects. Factor analysis, descriptive analysis, correlation analysis and regression analysis were used to explore the survey data. Findings – The analysis of the data reveals that the individual participant’s satisfaction with the management of an OSS project is an important factor influencing the extent of their personal contribution to a community. Originality/value – Little attention has been devoted to understanding the impact of management in OSS communities. Focused on OSS developers specialising in web development, the findings of this paper offer an important original contribution to understanding the connections between individual members’ satisfaction with management and their motivations to contribute to an OSS project. The findings reveal that motivations to share knowledge in online communities are influenced by the quality of management. Consequently, the findings suggest that appropriate management can enhance knowledge sharing in OSS projects and online communities, and organisations more generally.

Purpose Overview of coaching for recovery. The paper aims to show an overview of work that was carried out over 11 years with groups of mental health and physical staff. As the facilitator who had run this course for the duration in Nottingham, this was an excellent opportunity to be at the forefront of a brand new project. Design/methodology/approach The introduction of the skills are taught over two consecutive days followed by a further day a month later. The idea of coaching is to be enabled to find the answers in themselves by the use of powerful questions and using the technique of the grow model, combined with practice enables the brain to come up with its own answers. Using rapport and enabling effective communication to deliver the outcome. Findings Evidence from staff/clients and the purpose of the paper shows that when you step back it allows the individual patients/staff to allow the brain to process to create to come up with their solutions, which then helps them to buy into the process and creates ownership. Research limitations/implications The evidence suggests that the approach that was there prior to the course was very much a clinical approach to working with clients and treating the person, administering medication and not focussing on the inner person or personal recovery. The staff review has shown that in the clinical context change is happening from the inside out. Practical implications “Helps change culture”; “change of work practice”; “it changed staff focus – not so prescriptive”; “powerful questions let clients come to their own conclusions”; “coaching gives the ability to find half full. Helps to offer reassurance and to find one spark of hope”. Social implications This has shown that the approach is now person-centred/holistic. This has been the “difference that has made the difference”. When this paper looks at the issues from a different angle in this case a coaching approach, applying technique, knowledge and powerful questions the results have changed. The same clients, same staff and same problems but with the use of a different approach, there is the evidence of a different outcome, which speaks for itself. The coaching method is more facilitative, therefore it illicit’s a different response, and therefore, result. Originality/value The results/evidence starts with the individual attending and their commitment to the process over the two-day course. Then going away for the four weeks/six for managers and a commitment again to practice. Returning to share the impact if any with the group. This, in turn, helps to inspire and gain motivation from the feedback to go back to work invigorated to keep going.

Purpose Creativity itself does not necessarily lead to idea implementation. The purpose of this paper is to deeply understand the impact of the individual culture value orientation on employees’ motivation on whether they want to push creative ideas into implementation. Design/methodology/approach In this study, drawing on socially desirable responding (SDR) theory, the author reasons that individual value on power distance and superficial harmony and that these two factors interact to influence employees transform their creativity into implementation. The author argues that prevalence of the failure where creativity cannot be transformed into implementation results from the lack of understanding for two elusive individual culture value orientations: individual superficial harmony orientations (ISHO) and individual power distance orientations (IPDO). Data from 66 middle managers and 301 members of five high-tech firms provide a considerable support for the hypothesized model. Findings The results showed that individuals were able to improve the possibility of putting their creative ideas into practice when they are both lower in IPDO and ISHO. Originality/value Such findings help the author to understand how individual cultural value orientation complements each other to generate joint impact on the relationship between their creative ideas to idea implementation.

Purpose Narratives are central to consumers’ understanding of brands especially during change. The financial crisis that began in 2008 offered a changing marketplace from which to develop two managerially useful frameworks of consumer narratives. The paper aims to discuss these issues. Design/methodology/approach Consumer focus groups, interviews with bankers and qualitative consumer surveys were used to gather consumers’ narratives about retail banking. The narratives were examined through frameworks from both the humanities and psychology (narrative identity). Findings The individual consumer narratives were used to create first a possible cultural narrative or bird’s eye view and later archetypal narratives of groups of consumers for a ground-level view of the changing marketplace. Research limitations/implications Like all early research, the findings must be examined in other contexts to improve generalizability. Practical implications The narrative results revealed the impact of change on consumers’ identities, views of other entities and retail banking activity to yield managerially actionable information for segmentation, target marketing, branding and communication. Originality/value Frameworks are developed for consumer narratives which are shown to be useful tools in examining consumers’ reactions to changing markets and in formulating marketing responses.

The Impact

Purpose – The purpose of this paper is to draw out the lessons learned from the implementation of the Individual Placement and Support (IPS) approach to supported employment in two contrasting adult mental health teams; one “standard” CMHT, and one early intervention in psychosis (EIP) team. Design/methodology/approach – These inferences are based on the evidence from a four-year study of IPS in one mental health care provider in the UK, which began by setting up a new service, and went on to run a RCT looking at the impact of psychological input as an adjunct to IPS alone. Findings – In attempting to introduce IPS to mental health teams in Nottingham the authors came across numerous barriers, including service reorganisation, funding cuts and the wider context of recession. Differences were observed between mental health teams in the willingness to embrace IPS. The authors argue that this variability is due to differences in caseload size, recovery priorities and client profiles. The authors have learnt that perseverance, strenuous efforts to engage clinical staff and the use of IPS fidelity reviews can make a positive difference to the implementation process. Practical implications – The experience suggests that setting up an IPS service is possible even in the most challenging of times, and that EIP services may be a particularly fertile ground for this approach. The authors also discuss potential barriers to implementing new services in mental health teams. Originality/value – This paper will be of value to service development and the science of implementation in mental health.

Purpose The purpose of this study is to investigate the impact of artificial intelligence (AI) on the human rights issue. This study has also examined issues with AI for business and its civil and criminal liability. This study has provided inputs to the policymakers and government authorities to overcome different challenges. Design/methodology/approach This study has analysed different international and Indian laws on human rights issues and the impacts of these laws to protect the human rights of the individual, which could be under threat due to the advancement of AI technology. This study has used descriptive doctrinal legal research methods to examine and understand the insights of existing laws and regulations in India to protect human rights and how these laws could be further developed to protect human rights under the Indian jurisprudence, which is under threat due to rapid advancement of AI-related technology. Findings The study provides a comprehensive insight on the influence of AI on human rights issues and the existing laws in India. The study also shows different policy initiatives by the Government of India to regulate AI. Research limitations/implications The study highlights some of the key policy recommendations helpful to regulate AI. Moreover, this study provides inputs to the regulatory authorities and legal fraternity to draft a much-needed comprehensive policy to regulate AI in the context of the protection of human rights of the citizens. Originality/value AI is constantly posing entangled challenges to human rights. There is no comprehensive study, which investigated the emergence of AI and its influence on human rights issues, especially from the Indian legal perspective. So there is a research gap. This study provides a unique insight of the emergence of AI applications and its influence on human rights issues and provides inputs to the policymaker to help them to draft an effective regulation on AI to protect the human rights of Indian citizens. Thus, this study is considered a unique study that adds value towards the overall literature.

PurposeWithin the expatriation subset of the wider IB literature, the focus of research has been on contemporary contextual factors. The purpose of this paper is to link the present to the past by investigating how the individual expatriate experience may be affected by a colonial legacy between host and home countries.Design/methodology/approachGiven the exploratory nature of this study, a qualitative interview-based approach eliciting thick, detailed descriptions of the practical experiences of seven Japanese expatriate managers working in Malaysia was adopted. These were supplemented by additional interviews with three host-country nationals who work alongside some of the expatriates. The data were analysed through a two-stage coding process.FindingsThe expatriate respondents were largely unanimous in their view that the colonial past between the two countries had no negative impact on their experiences in Malaysia, and the Malaysian interviewees corroborated this. On the contrary, the majority of the expatriates actually spoke positively about their experiences. This was especially true for expatriates in both the tourism and education/research field whose work was linked in some way to the period of Japanese occupation.Research limitations/implicationsThe small, single-context nature of the investigation limits generalisation. There are also many particularities in this study (the nature of Japanese-Malaysian postcolonial relations, cultural values of the Malaysians and Japanese, and so on) that are perhaps not easily relatable to other contexts. Having said this, qualitative research is not always geared towards generalisability but rather towards contextual intricacies and nuances.Originality/valueWhile most of the extant literature on expatriation has examined largely contemporary factors, this paper explores the impact of more historical events on the expatriate experience. Although such events may seem distant from an expatriate's current activities, this study suggests that in certain circumstances, they may have a lingering effect.

The Relationship

Purpose This study aims to explore the ways in which young people and prison staff (Prison Officers) within a youth custodial establishment experience empathy. Previous research tends to view empathy as a stable trait and one which people can develop through individual-centred therapy. There has been little consideration of the impact of relationship factors and context in relation to empathy experience and expression. The current study aims to address this by exploring the role of the custodial context in shaping empathy, including the potential impact of relationships, environmental factors and culture. Design/methodology/approach A qualitative approach was used to enable breadth and depth in the exploration of this area. Individual, semi-structured interviews were carried out with a purposive sample of three young people and three Prison Officers. Data was analysed using inductive thematic analysis informed by the guidelines of Braun and Clarke (2006) and King and Horrocks (2010). Findings Constructed themes included “constructions of empathy”, “recipe for empathy”, “institutional investment”, “the value of empathy” and “doing empathy”. Together, they provide detailed insight into the interplay of personal and wider contextual factors influencing the experience of empathy in a custodial setting. The findings suggest that the way in which young people and staff experience empathy in the custodial environment is unique. The findings suggest that empathy takes place within the context of relationships and is influenced by the nature of those relationships, along with the wider social context within which it occurs. Practical implications The findings of the current study support a move away from understanding empathy as an individual personality trait and instead viewing it as a dynamic experience that is changeable based upon the relationship and the context within which it occurs. The findings suggest that interventions aiming to develop empathy should look beyond the level of the individual and the relationship and focus upon developing environments that are supportive of empathy. Originality/value This study provides unique insights into the subjective experience of empathy in a custodial setting, presenting as one of the first to take a more holistic approach to understand this phenomenon.

The Impact

Purpose The recent increase in economic inequalities in many countries heightened the debates about policy preferences on income distribution. Attitudes toward inequality vary greatly across countries and numerous explanations are offered to clarify the factors leading to support for redistribution. The purpose of this paper is to examine the link between subjective social class and redistributive demands by jointly considering the individual and national factors. The author argues that subjective measures of social positions can be highly explanatory for preferences about redistribution policies. Design/methodology/approach The author uses data from 48 countries gathered by World Values Survey and empirically tests the impact of self-positioning into classes by multilevel ordered logit model. Several model specifications and estimation strategies have been employed to obtain consistent estimates and to check for the robustness of the results. Findings The findings show that, in addition to objective factors, subjective class status is highly explanatory for redistributive preferences across countries. The author also exhibits that there is interaction between self-ranking of social status and national context. The author’s estimations from the multilevel models verify that subjective social class has greater explanatory power in more equal societies. This is in contrast to the previous studies that establish a positive link between inequality and redistribution. Originality/value The paper contributes to the literature by introducing subjective social class as a determinant. Self-ranked positions can be very relieving about policy preferences given the information these categorizations encompass about individuals’ perceptions about their and others’ place in the society.

Purpose The purpose of this paper is to study the disposition effect that is exhibited by the investors through the review of research articles in the area of behavioral finance. When the investors are hesitant to realize the losses and quick to realize the gains, this phenomenon is known as the disposition effect. This paper explains various theories, which have been evolved over the years that has explained the phenomenon of disposition effect. It includes the behavior of individual investors, institutional investors and mutual fund managers. Design/methodology/approach The authors have used the existing literatures from the various authors, who have studied the disposition effect in either real market or the experimental market. This paper includes literature over a period of 40 years, that is, Dyl, 1977, in the form of tax loss selling, to the most recent paper, Surya et al. (2017). Some authors have used the PGR-PLR ratio for calculating the disposition effect in their study. However, some authors have used t-test, ANNOVA, Correlation coefficient, Standard deviation, Regression, etc., as a tool to find the presence of disposition effect. Findings The effect of disposition can be changed for different types of individual investors, institutional investors and mutual funds. The individual investors are largely prone to the disposition effect and the demographic variables like age, gender, experience, investor sophistication also impact the occurrence of the disposition effect. On the other side, the institutional investors and mutual funds managers may or may not be affected by the disposition effect. Practical implications The skilled understanding of the disposition effect will help the investors, financial institutions and policy-makers to reduce the adverse effect of this bias in the stock market. This paper contributes a detailed explanation of disposition effect and its impacts on the investors. The study of disposition effect has been found to be insufficient in the context of Indian capital market. Social implications The investors and society at large can gains insights about causes and influences of disposition effect which will be helpful to create sound investment decisions. Originality/value This paper has complied the 11 causes for the occurrence of disposition effect that are found by the different authors. The paper also highlights the impact of the disposition effect in the decision-making of various investors.
