Dual diagnosis in older drinkers during the COVID-19 pandemic
Authors: Rao Rahul , Mueller Christoph , Broadbent Matthew 
Published: May 2021

PurposeThere is a dearth of literature examining the impact of the COVID-19 pandemic on older people with dual diagnosis referred to mental health services. The purpose of this study was to compare dual diagnosis before and after lockdown in people aged between 55 and 74 with alcohol use.Design/methodology/approachData were collected for people referred to mental health services using an anonymised database of de-identified records to identify people with both substance use disorder alone, or accompanied by co-existing mental disorders.FindingsIn total, 366 older people were assessed with the Alcohol Use Disorders Identification Test (AUDIT), 185 before and 181 after lockdown. People with dual diagnosis were more likely to be referred than those without, after compared to before lockdown (13 and 6%, respectively, p < 0.05). People with any substance use disorder with and without dual diagnosis showed an even greater likelihood of referral after, compared with before, lockdown (61 and 34%, respectively, p < 0.0001). Opioid use more than once a month was more likely to be reported after, compared with before, lockdown (66 and 36%, respectively, p < 0.005).Research limitations/implicationsThe finding of a higher likelihood of opioid use after compared with before lockdown during the COVID-19 pandemic warrants further exploration. There is also further scope for further studies that involve older non-drinkers.Originality/valueA greater likelihood of both dual diagnosis and substance use disorder alone after, compared with before lockdown has implications for both mental health and addiction service provision during a pandemic.

Authors: Naveed Muhammad , Zia Muhammad Qamar , Younis Sobia , Shah Zubair A. 
Published: May 2021

Purpose
The purpose of the study is to probe the influence of individual social entrepreneurship orientations (ISEO) and SE education (SEE) which could affect social entrepreneurial intentions (SEI) among students.

Design/methodology/approach
The data were gathered from 241 entrepreneurship discipline university students. The data were analyzed with structural equation modeling.

Findings
Findings suggest that ISEO plays a vital role in stimulating SEI; moreover, SEE further moderates ISEO and SEI's relationship among students.

Practical implications
Based on the results, academia should focus on SEE and the government should devise policies to encourage social entrepreneurial ventures to aid in social problems solution.

Originality/value
This study validates the relationship of different factors (orientations and intentions) of the theory of planned behavior in the SE domain and confirms the significance of SEE.
Influence of an individual’s unethical behaviour on peers’ vicarious learning in organisations: the role of moral anger
Authors: Zeng Kai , Wang Duanxu , Ye Qingyan , Li Zhengwei , Zheng Xianwei 
Published: May 2021

PurposeBecause unethical behaviour pervades in organisations, how to inhibit the interpersonal influence of unethical behaviour has become increasingly important. This study aims to integrate the deontic justice theory and affective events theory to examine the relationship between an individual’s unethical behaviour and his or her peers’ vicarious learning by highlighting the mediating effect of peers’ moral anger and the moderating effect of task interdependence on this relationship.Design/methodology/approachData were collected in two waves from 254 employees of a large manufacturing company in the People’s Republic of China.FindingsThe hypothesised moderated mediation model was supported. Specifically, as expected, peers’ moral anger mediated the negative relationship between an individual’s unethical behaviour and peers’ vicarious learning. Task interdependence moderated the direct relationship between the individual’s unethical behaviour and his or her peers’ moral anger and the indirect relationship between an individual’s unethical behaviour and his or her peers’ vicarious learning via the peers’ moral anger such that these relationships were stronger when the level of task interdependence was higher.Originality/valueThis study argues that the deontic justice theory is a supplement for the social learning theory in explaining the interpersonal influence of unethical behaviour. Drawing on the deontic justice theory, this study demonstrates that an individual’s unethical behaviours are unlikely to be rewarded or accepted, and by integrating the theories of deontic justice and affective events, offers a rationale for the emotional mechanism that underlies the interpersonal influence of unethical behaviour.
Novel coupled analysis methods of automotive alternators considering synchronous rectification circuit
Authors: Hidaka Yuki 
Published: May 2021

Purpose
The purpose of this paper is to develop a novel coupled analysis method for synchronous rectification alternators.

Design/methodology/approach
An ideal diode module is embedded in a rectification circuit. The resistance of the diode module is set such that it is equal to the on-resistance of the MOS-FET modules in the generation mode. In a mode without power generation, the motor voltage is less than the bus voltage; a sufficiently large value is defined for simulating the infinite resistance.

Findings
Because there is no need to decide the switch timing in advance, only one round of coupled analysis is needed to evaluate the synchronous rectification alternators.

Research limitations/implications
As limited case study is denoted in this paper, much more case studies are needed to be discussed.

Practical implications
By using the proposed method, it can be fulfilled that generation characteristic of automotive alternators can be evaluated without using the control simulation or pre-conducted analysis to decide the switch timing.

Social implications
By using the proposed method, it can be fulfilled that generation characteristic of automotive alternators can be evaluated without using the control simulation or pre-conducted analysis to decide the switch timing.

Originality/value
In the proposed methods, the definition of diode module differs from that of a conventional coupled analysis.
Known and anticipated medical geology issues in Ghana
Authors: Kazapoe Raymond Webrah , Arhin Emmanuel , Amuah Ebenezer Ebo Yahans 
Published: May 2021

Purpose
This paper aims to review the known and anticipated medical geology problems in Ghana, to highlight the impact of some trace elements on human health and to reveal some essential aspects of medical geology on health.

Design/methodology/approach
Literature and empirical studies relating to medical geological issues in Ghana were reviewed. Secondary data were used in the present study such as case studies, reports, geological bulletins and published research studies.

Findings
High levels of heavy metals including arsenic, cadmium and mercury in gold extraction processes through artisanal small-scale mining have contributed to high concentrations of toxic elements in the environment. The distribution and availability of these elements in the environment are facilitated by the geological, chemical and local environmental activities that are irregularly spread exposing people mining areas to pollutions. Exposures to these elements in above and below baseline levels contributed to health implications including fluorosis, intellectual or developmental disability and death in some regions of Ghana. Cardiovascular and cerebrovascular diseases linked to mining activities were also presented in this study. Similarly, non-communicable diseases can affect many people if correct measures are not considered. Following the geometric increase in mining activities, it is anticipated that deleterious environmental and health impacts associated with mining may persist in mining areas in Ghana. Reported implications and continuous contamination of water bodies in mining areas could result in high pollution levels beyond treatment for human use or destroy aquatic habitats and aquatic lives through acid drainage. Above-threshold concentrations of heavy metals in soils could bio-accumulate in crops, and this could pose deleterious public health implications on consumers. Continuous effects posed on the environment and public health may prompt communities, regulatory institutions and government to reduce or ban mineral development.

Originality/value
This review has significantly revealed potential public health issues from the impact on the natural environment and recommends that medical geologists work together with medical workers to devise preventive and therapeutic techniques to address many geology-related-health issues in Ghana.
Twitter users’ coping behaviors during the COVID-19 lockdown: an analysis of tweets using mixed methods
Authors: Mittal Ruchi , Ahmed Wasim , Mittal Amit , Aggarwal Ishan 
Published: May 2021

Purpose
Using data from Twitter, the purpose of this paper is to assess the coping behaviour and reactions of social media users in response to the initial days of the COVID-19-related lockdown in different parts of the world.

Design/methodology/approach
This study follows the quasi-inductive approach which allows the development of pre-categories from other theories before the sampling and coding processes begin, for use in those processes. Data was extracted using relevant keywords from Twitter, and a sample was drawn from the Twitter data set to ensure the data is more manageable from a qualitative research standpoint and that meaningful interpretations can be drawn from the data analysis results. The data analysis is discussed in two parts: extraction and classification of data from Twitter using automated sentiment analysis; and qualitative data analysis of a smaller Twitter data sample.

Findings
This study found that during the lockdown the majority of users on Twitter shared positive opinions towards the lockdown. The results also found that people are keeping themselves engaged and entertained. Governments around the world have also gained support from Twitter users. This is despite the hardships being faced by citizens. The authors also found a number of users expressing negative sentiments. The results also found that several users on Twitter were fence-sitters and their opinions and emotions could swing either way depending on how the pandemic progresses and what action is taken by governments around the world.

Research limitations/implications
The authors add to the body of literature that has examined Twitter discussions around H1N1 using in-depth qualitative methods and conspiracy theories around COVID-19. In the long run, the government can help citizens develop routines that help the community adapt to a new dangerous environment – this has very effectively been shown in the context of wildfires in the context of disaster management. In the context of this research, the dominance of the positive themes within tweets is promising for policymakers and governments around the world. However, sentiments may wish to be monitored going forward as large-spikes in negative sentiment may highlight lockdown-fatigue.

Social implications
The psychology of humans during a pandemic can have a profound impact on how COVID-19 shapes up, and this shall also include how people behave with other people and with the larger environment. Lockdowns are the opposite of what societies strive to achieve, i.e. socializing.

Originality/value
This study is based on original Twitter data collected during the initial days of the COVID-19-induced lockdown. The topic of “lockdowns” and the “COVID-19” pandemic have not been studied together thus far. This study is highly topical.
Triple grief cycle of cancelled events: the emotional crisis aftermath
Authors: Wong IpKin Anthony , Lin Shuyi , Lin Lixin , Liao Ruobing 
Published: May 2021

Purpose
The coronavirus (COVID-19) pandemic response is not only devastating nations and economies across the globe but it is also severely disrupting the event industry, with government and health authorities forcing many events to be postponed or cancelled. The purpose of this study is to investigate the prospective attendees’ emotional responses to cancelled events. This study draws upon grief cycle theory to articulate different layers of the grief process in the event domain of inquiry.

Design/methodology/approach
The National Collegiate Athletic Association basketball tournament was selected as the research context. Taking user-generated messages from Twitter, this study first performed content analysis to organize lexical patterns into categories and higher-order themes based on the grief cycle. It also performed social network analyses using UCINET to illustrate how different grief phases are inter-related.

Findings
Results not only point to attendees’ self-expression manifested through a continuum of denial, anger, bargaining and acceptance but they also reveal a three-layer hierarchy of grief, namely, event-related, socio-politics-related and crisis-related. The network analysis further illustrates how grief phases are tied into a complex network of grief messages.

Originality/value
This study advances the event literature by improving knowledge about attendees’ emotional responses to cancelled events. It increases our understanding of the grieving process in the aftermath of COVID-19. The proposed triple grief cycle helps advance the literature by showcasing how voices from prospective attendees represent three pillars of grief hierarchy. The findings also underscore the emotional crisis of the COVID-19 aftermath.
COVID-19 and incarcerated older adults: a commentary on risk, care and early release in Australia
Authors: Hwang Ye In (Jane) , Ginnivan Natasha Ann , Simpson Paul Leslie , Baidawi Susan , Withall Adrienne , Williams Brie , Butler Tony 
Published: May 2021

Purpose
The purpose of this commentary is to draw upon available literature and practices related to COVID-19 and management of older incarcerated adults in Australia to highlight key matters for better risk management and care of this population during this and future infectious disease pan/epidemics.

Design/methodology/approach
The present commentary draws on current policies, practices and literature regarding the health, needs and management of older incarcerated adults in Australia to discuss risk, care and early release for this population during the COVID-19 pandemic.

Findings
Incarcerated persons experience poorer health and accelerated age-related decline compared to those in the general community. The present situation offers the opportunity to fill knowledge and practice gaps, including policies for staff training, identification of dementia and cognitive decline, assessment of mobility issues, addressing barriers to health-seeking, possibilities of medical or compassionate release, risk assessment and release protocols and post-release needs.

Practical implications
While Australian prisons have acknowledged the vulnerability of older persons, more focused adaptation of COVID-19-related policies to consider adults as young as 45 years are needed. Appropriate ethical identification and management of cases in this population is needed, as is discussion on issues of decarceration and medical release. Re-conceptualisation of incarcerated adults as “citizens in need of care”, rather than as “offenders to be secured”, will be beneficial. Robust, local evidence is needed to assist decision-making.

Originality/value
This is a comprehensive, focused review of relevant evidence, policies and practices for a growing subpopulation of prisoners worldwide with complex needs and particular vulnerability to the COVID-19.
Islamic index market sentiment: evidence from the ASEAN market
Authors: Danila Nevi , Kamaludin Kamilah , Sundarasen Sheela , Bunyamin Bunyamin 
Published: May 2021

Purpose
The purpose of this paper is to examine investor sentiment by measuring the impact of market sentiment shocks on the volatility of the Islamic stock index of five ASEAN countries, with noise traders as a proxy for market sentiment.

Design/methodology/approach
The GJR-GARCH model is used to capture the empirically observed fact that negative shocks in the past period have a stronger impact on variance than positive shocks in the present.

Findings
All five ASEAN Islamic stock indices show clustering volatility. However, only three countries, namely, Malaysia, Thailand and Singapore, demonstrate leverage effects. In addition, the effect of market sentiment on Islamic stock index returns is observed in the Indonesian and Malaysian markets, which are the two largest Islamic markets with a dominant Muslim population in the ASEAN. This finding implies that the trading behaviours of Muslim investors in the Shariah market are the same as their behaviours in the conventional market, that is, nonadherence to the Sunnah.

Practical implications
Whilst establishing investment strategies, creating portfolios and providing client-advisory services, investors and fund managers should factor in the presence of market sentiment and its impact on stock performance and volatility. In addition, a capital market system preventing rumour-based transactions is compelling.

Social implications
In some markets, the Islamic financial products awareness should be increased through education to attract increased domestic investors with the potential to boost growth in the Islamic stock market.

Originality/value
Investigation market sentiment impacts on the Islamic stock index using noise traders as a proxy.
Adaptive governance: learning from what organizations do and managing the role they play
Authors: van Assche Kristof , Valentinov Vladislav , Verschraegen Gert 
Published: May 2021

PurposeThe purpose of this paper is to deepen the understanding of adaptive governance, which is advocated for as a manner to deal with dramatic changes in society and/or environment. To re-think the possible contributions of organizations and organization theory, to adaptive governance.Design/methodology/approachBased on social systems theory this study makes a distinction between “governance organizations” and “governance communities.” Organizations are conceptualized as the decision machines which organize and (co-)steer governance. Communities are seen as the social environments against which the governance system orients its operations. This study considers the adaptive mechanisms of organizations and reflect on the roles of organizations to enhance adaptive governance in communities and societies.FindingsDiverse types of organizations can link or couple in different ways to communities in their social environment. Such links can enhance the coordinative capacity of the governance system and can also spur innovation to enable adaptation. Yet, linking with communities can also slow down responses to change and complexify the processes of deliberation in governance. Not all adaptive mechanisms available to organizations can be used in communicating with communities or can be institutionalized, but the continuous innovation in the field of organizations can inspire continuous testing of small-scale adaptive mechanisms at higher levels. Society can thus enhance its adaptive capacity by managing the role of organizations.Originality/valueThe harnessing of insights in organization theory and systems theory for improving understanding of adaptive governance. The finding that both experiment and coordination at societal level are needed, toward adaptive governance, and that organizations can contribute to both.
An overview on joining/welding as post-processing technique to circumvent the build volume limitation of an FDM-3D printer
Authors: Tiwary Vivek Kumar , P. Arunkumar , Malik Vinayak R. 
Published: May 2021

Purpose
Three-dimensional (3D) printing, one of the important technological pillars of Industry 4.0, is changing the landscape of future manufacturing. However, the limited build volume of a commercially available 3D printer is one inherent constraint, which holds its acceptability by the manufacturing business leaders. This paper aims to address the issue by presenting a novel classification of the possible ways by which 3D-printed parts can be joined or welded to achieve a bigger-sized component.

Design/methodology/approach
A two-step literature review is performed. The first section deals with the past and present research studies related to adhesive bonding, mechanical interlocking, fastening and big area additive manufacturing of 3D printed thermoplastics. In the second section, the literature searches were focused on retrieving details related to the welding of 3D printed parts, specifically related to friction stir welding, friction (spin) welding, microwave and ultrasonic welding.

Findings
The key findings of this review study comprise the present up-to-date research developments, pros, cons, critical challenges and the future research directions related to each of the joining/welding techniques. After reading this study, a better understanding of how and which joining/welding technique to be applied to obtain a bigger volume 3D printed component will be acquired.

Practical implications
The study provides a realistic approach for the joining of 3D printed parts made by the fused deposition modeling (FDM) technique.

Originality/value
This is the first literature review related to joining or welding of FDM-3D printed parts helping the 3D printing fraternity and researchers, thus increasing the acceptability of low-cost FDM printers by the manufacturing business leaders.
Corporate social responsibility, business group affiliation and shareholder wealth: evidence from an emerging market
Authors: Velayutham Eswaran , Ratnam Vijayakumaran 
Published: May 2021

PurposeThis paper aims to examine the relationship between corporate social responsibility (CSR) and shareholder wealth arising from announcement returns of security issuance from a frontier market. It also explores the role of business group affiliation (BGA) on this relationship.Design/methodology/approachThe study uses short-term scenarios to examine the link between CSR and shareholder wealth using the event study methodology which helps us mitigate the reverse causality problems related to studies of the relationship between CSR and firm value. Abnormal returns surrounding the security issue announcements were generated using the market model.FindingsThis paper finds that security issuers with high CSR scores are associated with higher shareholder value. However, this paper finds that CSR activities of security issuers with BGA are value-destroying which is consistent with the agency perspective of CSR.Research limitations/implicationsThis study is limited to only one nascent market, namely the Colombo Stock Exchange.Originality/valueThis study documents that CSR and BGA are important determinants, among others, of stock price reactions to security offerings in emerging markets.
