Abstract
Purpose
In this paper, the main focus is on supply and demand auction systems with resource pooling in modern supply chain from a theoretical modeling perspective. The supply and demand auction systems in modern supply chains among manufacturers and suppliers serve as information sharing mechanisms. The purpose of this paper is to match the supply and demand such that a modern supply chain can achieve incentive compatibility and economic efficiency. The authors design such a supply and demand auction system that can integrate resources to efficiently match the supply and demand.
Design/methodology/approach
The authors propose three theoretic models of modern supply chain auctions with resource pooling according to the Vickrey auction principle. They are supply auction model with demand resource pooling, demand auction model with supply resource pooling, and double auction model with demand and supply resource pooling. For the proposed auction models, the authors present three corresponding algorithms to allocate resources in the auction process by linear programming, and study the incentive compatibility and define the Walrasian equilibriums for the proposed auction models. The authors show that the solutions of the proposed algorithms are Walrasian equilibriums.
Findings
By introducing the auction mechanism, the authors aim to realize the following three functions. First is price mining: auction is an open mechanism with multiple participants. Everyone has his own utility and purchasing ability. So, the final price reflects the market value of the auction. Second is dynamic modern supply chain construction: through auction, firm can find appropriate partner efficiently. Third is resources integration: in business practices, especially in modern supply chain auctions, auctioneers can integrate resources and ally buyers or sellers to gain more efficiency in auctions.
Originality/value
In the paper, the authors propose three theoretic models and corresponding algorithms of modern supply chain auctions with resource pooling according using the Vickrey auction principle, which achieves three functions: price mining, dynamic modern supply chain construction and resources integrating. Besides, these proposed models are much closer to practical settings and may have potential applications in modern supply chain management.

Abstract
Purpose
The purpose of this paper is to examine the determinants of users’ simulated experience in a virtual store and to show the subsequent impact of that experience on engagement. The outcome of that engagement is examined in relation to enjoyment, satisfaction and purchase intentions.
Design/methodology/approach
The method comprised an experiment comparing users’ perceptions of a standard 2D online clothing store with an enhanced, immersive one that aimed to provide shopping value approaching that of a traditional store by using a 3D experience where participants wore special glasses and a data glove.
Findings
Results demonstrate the major role of telepresence components in simulated experience and the critical role of that experience, along with hedonic and utilitarian values, in engagement. Purchase intention is influenced by satisfaction, which is in turn influenced by enjoyment and engagement. Engagement in turn is influenced by utilitarian and hedonic value and the experience of product simulation or telepresence, which is composed of control, colour and graphics vividness, and 3D authenticity. In the immersive, 3D environment, experience is more associated with engagement and enjoyment, leading to greater purchase intention. The immersive, 3D environment, thus, has the potential to rival traditional shopping in terms of experience, resulting in higher sales for retailers and satisfaction for consumers.
Originality/value
This work has evaluated a robust model of purchase intention and demonstrated it to hold not only in a 3D environment on a conventional computer platform, but also in an immersive one, where participants wear special glasses and a data glove.

This study aims to explore the experiences of living through the COVID-19 pandemic for people who faced homelessness and dealt with mental health and/or substance use challenges.
Abstract
Purpose
This study aims to explore the experiences of living through the COVID-19 pandemic for people who faced homelessness and dealt with mental health and/or substance use challenges.
Design/methodology/approach
This qualitative study was comprised of 26 1:1 interviews (16 men and 10 women), conducted between February and May 2021 with people who experienced homelessness in North East England during the COVID-19 pandemic. An inductive reflexive thematic analysis was undertaken, with input from individuals with lived experience who were involved throughout the study.
Findings
Four themes were developed. The first theme, lack of support and exacerbation of mental health and substance use difficulties, highlighted how the lack of in-person support and increased isolation and loneliness led to relapses or new challenges for many people’s mental health and substance use. The second theme, uncertainty and fear during the pandemic, explored how the “surreal” experience of the pandemic led to many people feeling uncertain about the future and when things would return to normal. The third theme, isolation and impacts on social networks, discussed how isolation and changes to relationships also played a role in mental health and substance use. Finally, opportunity for reflection and self-improvement for mental health and substance use, explored how some people used the isolated time to re-evaluate their recovery journey and focus on self-improvement.
Practical implications
The experiences shared within this study have important implications for planning the future delivery and commissioning of health and social care services for people facing homelessness, such as sharing information accessibly through clear, consistent and simple language.
Originality/value
As one of the few papers to involve people with lived experience as part of the research, the findings reflect the unique narratives of this population with a focus on improving services.

Abstract
Purpose
The purpose of this paper is to review the evidence of alcohol use disorders within the different stages of the criminal justice system in the UK. Furthermore it reviewed the worldwide evidence of alcohol brief interventions in the various stages of the criminal justice system.
Design/methodology/approach
A rapid systematic review of publications was conducted from the year 2000 to 2014 regarding the prevalence of alcohol use disorders in the various stages of the criminal justice system. The second part of the work was a rapid review of effectiveness studies of interventions for alcohol brief interventions. Studies were included if they had a comparison group. Worldwide evidence was included that consisted of up to three hours of face-to-face brief intervention either in one session or numerous sessions.
Findings
This review found that 64-88 per cent of adults in the police custody setting; 95 per cent in the magistrate court setting; 53-69 per cent in the probation setting and 5,913-863 per cent in the prison system and 64 per cent of young people in the criminal justice system in the UK scored positive for an alcohol use disorder. There is very little evidence of effectiveness of brief interventions in the various stages of the criminal justice system mainly due to the lack of follow-up data.
Social implications
Brief alcohol interventions have a large and robust evidence base for reducing alcohol use in risky drinkers, particularly in primary care settings. However, there is little evidence of effect upon drinking levels in criminal justice settings. Whilst the approach shows promise with some effects being shown on alcohol-related harm as well as with young people in the USA, more robust research is needed to ascertain effectiveness of alcohol brief interventions in this setting.
Originality/value
This paper provides evidence of alcohol use disorders in the different stages of the criminal justice system in the UK using a validated tool as well as reviewing the worldwide evidence for short ( < three hours) alcohol brief intervention in this setting.

Abstract
Purpose
Previous research has found mixed evidence of an attitude–behavior gap in organic food consumption. However, the complex mechanisms underlying this gap warrant further investigation. The purpose of this study is to examine the role of word-of-mouth (WOM), trust, and involvement in the relationship between consumer organic food attitudes and conative loyalty. The Theory of Planned Behavior (TPB) was used as underlying framework for modeling our conceptualized arguments.
Design/methodology/approach
A moderation and moderated mediation analysis was performed on a cross-sectional sample of 1,011 Australian organic food consumers.
Findings
The results support the TPB-inspired moderated-mediation model. Specifically, the authors found moderated mediation effects of WOM, trust, and involvement on conative loyalty via attitudes toward organics.
Research limitations/implications
The cross-sectional research design and the focus solely on Australian consumers constitute limitations of this study.
Practical implications
The authors' findings imply that an analysis of the attitude–behavior gap should go beyond the testing of contingent consistency hypotheses and instead combine moderation and mediation mechanisms to better model consumer decision-making leading to conative loyalty. Practitioners would face a resource challenge when targeting low-trust, low-involvement, and low-WOM consumers as developing conative loyalty of these segments would require a longer-term approach through building favorable attitudes toward organic foods.
Originality/value
This study is one of the first to demonstrate the potential of examining the attitude–behavior gap in the organic food context through a moderated mediation lens in explaining the dynamics of conative loyalty.

Abstract
This chapter provides first insights into identities and communities of educational staff in one of the largest, multi-campus universities in Italy. This group of managers refers to those supporting teaching and learning in the light of emerging demands from the European strategy for universities which is positioning education at the frontline in today’s higher education institutions (HEIs).
These insights are compared with common issues surveyed among research managers and administrators (RMAs) working in the same as well as in other international HEIs using Evans’ ‘restricted’ and ‘extended’ models of professionalism.
Among findings, educational managers (EM) show awareness of their identity only as ‘professionals’ while RMAs may feel like ‘hybrid’ profiles. Unlike RMAs, EM report not having a strong sense of belonging to one community but feeling like they belong to a plethora of groups. In conclusion, there are no dominant ‘extended’ or ‘restricted’ traits for any of the two groups and they have both these attitudes to a certain extent as the results of this chapter will further explain.

Abstract
Purpose
The purpose of this paper is to highlight the role of positive emotions in generating workplace impacts and examine it through the application of an adapted appreciative inquiry process in the context of a work-based project aimed at promoting integrated working under challenging organisational circumstances.
Design/methodology/approach
The paper adopts a case study methodology which highlights how an organisation facing difficult circumstances (such as austerity measures, siloed cultures, constant threats of reorganisation, and requirement to work across occupational boundaries) adapted an appreciative inquiry intervention/method.
Findings
This paper found, first, that the utilisation of appreciative inquiry in the context of an adapted work-based project in difficult organisational circumstances generated positive emotions manifest through a compelling vision and action plans, second, that the impacts (such as a vision) can become entangled and therefore part of the wider ecological context which promotes pathways to such impact, but that, third, there are a various cultural and climate features which may limit the implementation of actions or the continuation of psychological states beyond the time-bound nature of the work-based project.
Practical implications
The paper illustrates how an organisation adapted a form of appreciative inquiry to facilitate organisational change and generated outcomes which were meaningful to the various occupational groupings involved.
Originality/value
This paper offers new evidence and insight into the adaptation of appreciative inquiry under challenging circumstances in the context of a work-based learning project. It also provides a richer picture of how positive emotion can manifest in ways which are meaningful to a localised context.

Abstract
Purpose
This paper aims to analyze the financial implications associated with Ugandan universities employing e-learning techniques and to suggest sound policy solutions to the problems the investigation found.
Design/methodology/approach
To illustrate how e-learning is used in Uganda, the study used a descriptive research design. The study used a quantitative methodology to highlight the various experiences associated with utilizing e-learning platforms from various universities. A questionnaire survey was distributed to university students, and the data were analyzed using descriptive statistics in order to understand the usage of e-learning and Persons correlation to understand the degree of the relationship between the study variables.
Findings
The study findings reveal that e-learning approaches in universities are favorably correlated with their financial implications (r = 0.598; p-value 0.05). It was excruciatingly difficult to access online learning resources and platforms, and there was a severe lack of power. Some academic staff members lacked adequate e-learning platform training, and students noted that e-learning eased communication between students and lecturers, whereas Internet subscription and acquisition of mobile devices were expensive.
Research limitations/implications
The research was limited to three districts in western Uganda, and thus, it may not be possible to extrapolate the results to the entire nation.
Practical implications
Universities are open to these changes since the digital world is moving more quickly, overall, and this trend has crept into education as well. Policymakers and other universities may utilize the study's findings to inform their decisions.
Originality/value
The study offers useful insights into how e-learning systems have altered university teaching methods.

Abstract
Purpose
The efficiency of each of an organization’s individual workers determines its effectiveness. The study aims to explore the relationship between human resource management (HRM) practices and organizational effectiveness with employee performance as a mediating variable.
Design/methodology/approach
Data were collected from 800 police officers in the Greater Accra and Tema regions. The data were supported by the hypothesized relationship. Construct reliability and validity was established through confirmatory factor analysis. The proposed model and hypotheses were evaluated using structural equation modeling.
Findings
The results show that career planning and employee performance were significantly related. Self-managed teams and employee performance were shown to be nonsignificantly related. Similarly, performance management and employee performance were shown to be nonsignificantly related. Employee performance significantly influenced organizational effectiveness. The results further indicate that employee performance mediates the relationship between HRM practices and organizational effectiveness.
Research limitations/implications
The generalizability of the findings will be constrained due to the research’s police service focus and cross-sectional data.
Practical implications
The study’s findings will serve as valuable pointers for the police administration in the adoption, design and implementation of well-articulated and proactive HRM practices to improve the abilities, skills, knowledge and motivation of officer’s to inordinately enhance the effectiveness of the service.
Originality/value
By evidencing empirically that employee performance mediates the relationship between HRM practice and organizational effectiveness, the study extends the literature.
