Do we always follow others? The impact of psychological distance on consumers’ observational learning modes
Authors: Gu Chenyan , Zhang Zhe , Hou Yuansi 
Published: September 2021

Purpose
To investigate the psychological mechanism of observational learning in the online retailing context, the purpose of this paper is to show how the psychological distance between consumers and products affects modes of observational learning.

Design/methodology/approach
Five experimental studies are conducted to test the hypotheses.

Findings
The findings show that which modes of observational learning are adopted by consumers is affected by consumers’ psychological distance. Specifically, when the psychological distance between consumers and products is proximal, consumers tend to adopt the termed adequate observational learning mode by considering the interaction of information about popularity and the breadth of appeal of a product to make purchase. However, when the psychological distance is distal, consumers would consider information of popularity and breadth of appeal separately without considering the interaction, termed as inadequate observational learning mode. The observed relationship between psychological distance and observational learning mode could be explained by the construal level.

Research limitations/implications
This research advances the observational learning and psychological distance literature by investigating the psychological mechanism behind observational learning modes. Limitations include the use of scenario-based experiments to test the hypotheses, investigation of a single product attribute (i.e. breadth of appeal) and assessment of popularity information by sales volume alone.

Practical implications
The current research provides a deeper understanding of consumer observational learning modes, which can help online retailers to develop effective product strategies and marketing tactics and, finally, achieve stronger competitive positions.

Originality/value
The present research contributes to the literature by examining the psychological mechanism involved in observational learning. This research distinguishes adequate and inadequate observational learning modes from the perspective of psychological distance.

Authors: Agarwal Shweta , Singh S.B. 
Published: September 2021

PurposeThe purpose of the paper is to analyze reliability characteristics of batch service queuing system with a single server model that envisages Poisson input process and exponential service times under first come, first served (FCFS) queue discipline.Design/methodology/approachWith the help of renewal theory and stochastic processes, a model has been designed to discuss the reliability and its characteristics.FindingsThe instantaneous and steady-state availability along with the maintenance model of the systems subject to generalized M/Mb/1 queuing model is derived, and a few particular cases for availability are obtained as well. For supporting the developed model, a case study on electrical distribution system (EDS) has been illustrated, which also includes a comparison for the system subject to M/Mb/1 queuing model and the system without any queue (delay).Originality/valueIt is a quite realistic model that may aid to remove congestion in the system while repairing.
Supplier performance in the public healthcare: internal social capital, logistics capabilities and supply chain risk management capabilities as antecedents in a developing economy
Authors: Tukamuhabwa Benjamin , Mutebi Henry , Isabirye Daniel 
Published: September 2021

PurposeThe purpose of this paper is twofold. First, it intends to explore the link between internal social capital, logistics capabilities, supply chain risk management (SCRM) capabilities and supplier performance. Second, the mediating effect of logistics capabilities between internal social capital and SCRM capabilities, and that of SCRM capabilities between logistics capabilities and supplier performance are also examined.Design/methodology/approachA theoretical model developed from the extant literature was empirically validated through a cross-sectional survey of 122 respondents in 52 public healthcare facilities in Uganda. The data were analysed using partial least square structural equation modeling (PLS-SEM).FindingsThe study found that internal social capital and SCRM capabilities are significant predictors of supplier performance. Internal social capital is positively and significantly related to logistics capabilities, and logistics capabilities are positively and significantly related to SCRM capabilities. The authors also found non-significant relationships between internal social capital and SCRM capabilities, and between logistics capabilities and supplier performance. Furthermore, it was revealed that logistics capabilities play a partial mediating role in the relationship between internal social capital and SCRM capabilities, while SCRM capabilities fully mediate between logistics capabilities and supplier performance.Originality/valueFurther to providing empirical evidence of the antecedents of supplier performance in the public healthcare in a developing economy, which has been evidently scant, this study provides initial empirical evidence of the mediating role of logistics capabilities in the relationship between internal social capital and SCRM capabilities and that of SCRM capabilities in the relationship between logistics capabilities and supplier performance. This is important for understanding the mechanism through which supplier performance can be enhanced.

Authors: Windapo Abimbola , Adediran Abdulrauf , Rotimi James Olabode Bamidele , Umeokafor Nnedinma 
Published: September 2021

Purpose
This study aims to investigate whether clients’ knowledge about construction procurement systems influence project performance objectives and the role of procurement systems on project performance objectives in South Africa.

Design/methodology/approach
Using a two-round survey, 90 usable questionnaires from construction professionals in South Africa plus 3 expert clients were collected. The data were analysed using descriptive statistics – means, percentages and the analytical hierarchy process to determine the rank of client project performance criteria, while inferential statistics – Pearson product-moment correlation was used in establishing the relationship between the level of clients’ knowledge and project performance.

Findings
It was found that the common procurement systems used are traditional, followed by management-oriented and integrated procurement systems. In addition, it emerged that client’s knowledge of procurement systems shows a positive relationship with the achievement of project performance objectives. Based on these findings, it is concluded that some procurement systems being selected by clients in South Africa are inappropriately selected. This is despite the emergence of more efficient procurement systems. If procurement systems are selected based on the knowledge of the client, it will give better chances of a successful project outcome.

Practical implications
The research suggests the need for clients to seek ways to improve their understanding or increase their knowledge of procurement systems in construction. Policymakers’ responsibilities in driving policies that will place responsibilities on clients to seek a reasonable way to improve their knowledge where possible is implied in the study.

Originality/value
It contributes to improving project performance by examining whether the level of knowledge possessed by a client influences project performance.
Is co-production working well in recovery colleges? Emergent themes from a systematic narrative review
Authors: Bester Karen Louise , McGlade Anne , Darragh Eithne 
Published: September 2021

Purpose
“Co-production” is a process in health and social care wherein service users and practitioners work in partnership. Recovery colleges (RCs) are educational establishments offering mental health education; a cornerstone feature is that courses are designed and delivered in parity by both mental health practitioners and “peers” – people with lived experience of mental illness. This paper aims to consider, through the identification of key themes, whether co-production within RCs is operating successfully.

Design/methodology/approach
The paper is a systematic review of qualitative literature. Relevant concept groups were systematically searched using three bibliographic databases: Medline, Social Care Online and Scopus. Articles were quality appraised and then synthesised through inductive thematic analysis and emergent trends identified.

Findings
Synthesis identified three key themes relating to the impact of co-production in RCs: practitioner attitudes, power dynamics between practitioners and service users, and RCs’ relationships with their host organisations. As a result of RC engagement, traditional practitioner/patient hierarchies were found to be eroding. Practitioners felt they were more person-centred. RCs can model good co-productive practices to their host organisations. The review concluded, with some caveats, that RC co-production was of high fidelity.

Originality/value
RC research is growing, but the body of evidence remains relatively small. Most of what exists examine the impact of RCs on individuals’ overall recovery and mental health; there is a limited empirical investigation into whether their flagship feature of parity between peers and practitioners is genuine.
Analysis ofTawarruqcontract in the Islamic profit rate swap (IPRS) implementation in Malaysia
Authors: Ahmad Azlin Alisa , Mohd Dasar Mohd Hafiz , Nik Abdul Ghani Nik Abdul Rahim 
Published: September 2021

PurposeThis study aims to analyse the Shariah issues in the implementation oftawarruqcontract in the Islamic profit rate swap (IPRS) instrument in Malaysia.Design/methodology/approachThis is a qualitative study in applying data analysis and semi-structured interview approaches. Data was collected from various documents including journals, articles and past studies conducted by scholars. To achieve the purpose of this study, the data is analysed based on thematic analysis.FindingsThe study found several Shariah issues regarding the implementation oftawarruqcontract in the IPRS instruments, which have remained a dispute amongst the Islamic financial scholars such as its profit-making purpose, encouragement of debt, impediment of shared risk concept, disputed underlying assets, a deception towards allowing riba and dual agency.Research limitations/implicationsThis study recommends several improvements such as the establishment of a neutral agency that does not represent any banking institution to manage thetawarruqcontract commodity purchase from Bursa Suq al-Sila’ (BSAS). In addition, a neutral agency can provide aid in terms of transaction facility or at least consultation service for clients to enable them to conduct the commodity transactions independently.Practical implicationsMoreover, guidelines should be established on the separation of the deadline to sign the agreement of appointment of a bank as the commodity purchase agent and the agreement of appointment of the bank as the commodity sale agent on behalf of clients. All transactions related totawarruqcontract commodity must be done through BSAS. The regulators and industry experts may create a guideline for the IPRS based on the issues and recommendations that have been discussed in this study.Originality/valueOn the basis of the analysis of the criticisms and issues in the implementation oftawarruqcontract in the IPRS instrument, the current study found that an intermediating institution is allowed to gain profits from transactions conducted so long as they are based on Shariah principles of contract in Islam. As there is no parameter specifically for IPRS, thus the suggested parameter can be used by policymakers such as the Central Bank of Malaysia to ensure the industry complies with Shariah principles.
Making the local and the decentralized governable: a study of the implementation of the Chinese Temples Ordinance
Authors: Fung Wan Yin Kimberly 
Published: September 2021

Purpose
This paper aims at illustrating how the local and the decentralized temple management bodies were made governable and governed through law.

Design/methodology/approach
This paper examines the implementation of Chinese Temples Ordinances (the Ordinance) and the activities of the Chinese Temples Committee (the Committee) in Hong Kong during colonial times by analyzing official archival records from 1920s to 1970s.

Findings
This paper delineates how the local and decentralized temple management bodies were made governable under the Ordinance. The Ordinance and the Committee translated Chinese temples into financial resources for Chinese charity activities managed by the elite merchant class. Chinese temples were also sometimes translated as obstacles for land development. Though there existed different representations of Chinese temples in practices, the Committee and related officials provided legal reasons under the same legal framework suggested by the Ordinance.

Originality/value
This paper suggests that folk religion as a research topic is not only relevant to studies of religious doctrine, belief and ritual performances. A study of the history of temple management bodies is also highly relevant to the study of colonial governance in Hong Kong. It adds value to the discussion on the trajectory of the development of local communities.
Morphological and behavioural differences facilitate tropical butterfly persistence in variable environments
Authors: Wenda Cheng , Xing Shuang , Nakamura Akihiro , Bonebrake Timothy C. 
Published: September 2021

AbstractThe thermal biology of ectotherms largely determines their abundance and distributions. In general, tropical species inhabiting warm and stable thermal environments tend to have low tolerance to cold and variable environments, which may restrict their expansion into temperate climates. However, the distribution of some tropical species does extend into cooler areas such as tropical borders and high elevation tropical mountains. Behavioural and morphological differences may therefore play important roles in facilitating tropical species to cope with cold and variable climates at tropical edges.We used field‐validated biophysical models to estimate body temperatures of butterflies across elevational gradients at three sites in southern China and assessed the contribution of behavioural and morphological differences in facilitating their persistence in tropical and temperate climates. We investigated the effects of temperature on the activity of 4,844 individuals of 144 butterfly species along thermal gradients and tested whether species of different climatic affinities—tropical and widespread (distributed in both temperate and tropical regions)—differed in their thermoregulatory strategies (i.e. basking). In addition, we tested whether thermally related morphology or the strength of solar radiation (when butterflies were recorded) was related to such differences.We found that activities of tropical species were restricted (low abundance) at low air temperatures compared to widespread species. Active tropical species were also more likely to bask at cooler body temperatures than widespread species. Heat gain from behavioural thermoregulation was higher for tropical species (when accounting for species abundance), and heat gain correlated with larger thorax widths but not with measured solar radiation.Our results indicate that physiological intolerance to cold temperatures in tropical species may be compensated through behavioural and morphological responses in thermoregulation in variable subtropical environments. Increasing climatic variability with climate change may render tropical species more vulnerable to cold weather extremes compared to widespread species that are more physiologically suited to variable environments.
Fit for Purpose? BRICS and Inner‐Group Conflicts
Authors: Brosig Malte 
Published: September 2021

AbstractThis contribution argues that BRICS is designed to manage inner‐group tensions indirectly by endorsing a number of pragmatic operating principles. However, these principles seem to work best at smaller scale conflicts but not larger armed confrontation. The article breifly discusses the internal operating procedures of the BRICS group followed by a discussion of their relative value vis‐à‐vis inner group conflict. The article finishes by exploring the role of smaller group members such as South Africa and their ability to dissipate political tensions.
p38 MAPK‐mediated loss of nuclear RNase III enzyme Drosha underlies amyloid beta‐induced neuronal stress in Alzheimer's disease

Published: September 2021

AbstractMicroRNAs (miRNAs) are small noncoding RNAs ubiquitously expressed in the brain and regulate gene expression at the post‐transcriptional level. The nuclear RNase III enzyme Drosha initiates the maturation process of miRNAs in the nucleus. Strong evidence suggests that dysregulation of miRNAs is involved in many neurological disorders including Alzheimer's disease (AD). Dysfunction of miRNA biogenesis components may be involved in the processes of those diseases. However, the role of Drosha in AD remains unknown. By using immunohistochemistry, biochemistry, and subcellular fractionation methods, we show here that the level of Drosha protein was significantly lower in the postmortem brain of human AD patients as well as in the transgenic rat model of AD. Interestingly, Drosha level was specifically reduced in neurons of the cortex and hippocampus but not in the cerebellum in the AD brain samples. In primary cortical neurons, amyloid‐beta (Aβ) oligomers caused a p38 MAPK‐dependent phosphorylation of Drosha, leading to its redistribution from the nucleus to the cytoplasm and a decrease in its level. This loss of Drosha function preceded Aβ‐induced neuronal death. Importantly, inhibition of p38 MAPK activity or overexpression of Drosha protected neurons from Aβ oligomers‐induced apoptosis. Taken together, these results establish a role for p38 MAPK‐Drosha pathway in modulating neuronal viability under Aβ oligomers stress condition and implicate loss of Drosha as a key molecular change in the pathogenesis of AD.
Clinical management of withdrawal from benzodiazepine anxiolytic and hypnotic medications
Authors: Baldwin David S. 
Published: September 2021

AbstractBenzodiazepines continue to be prescribed widely in the management of patients with insomnia or anxiety disorders, despite the availability and acceptability of alternative pharmacological and psychological treatments. Many patients will experience adverse effects during treatment and considerable distress when the dosage is reduced and stopped. Management of benzodiazepine withdrawal includes measures to prevent the development of dependence, careful attention to underlying medical conditions, medication consolidation and gradual dosage reduction, accompanying psychological interventions, occasional prescription of concomitant medication, and relapse prevention with on‐going support to address psychosocial stressors. There are needs for easier patient access to services with refined expertise and for further research to optimise strategies for preventing dependence and facilitating withdrawal.
A Genre of Failed Novelists and Poets: Exploring Ethnography through a Narrative Lens
Authors: Fikry Noha 
Published: September 2021

SummaryGuided by Ruth Behar’s provocation to explore how ethnography was born out of the writings of novelists and poets and building on a special issue of Anthropology and Humanism on the art of ethnography published in 2007, I explore the histories, potentials, and boundaries of ethnography as a genre and craft. Relying on narrative theory as a resource that can enrich ethnography, I provide a close reading of several ethnographies, focusing on issues of character, time, and plot. I argue that a focus on narrative helps ethnographers put in conversation multiple selves’ shifting roles in ethnography. Narrative provides tools to put in dynamic dialogue these different selves, animate our texts, and write more accessible and enjoyable ethnographies. On another level, consulting with narrative theory is a reminder to claim all our ancestors and take pride in ethnography as a queer genre whose strength lies in its openings and porous boundaries.

Published: September 2021

AbstractPurposeTo analyse and compare the number and interval of anti‐vascular endothelial growth factor (anti‐VEGF) injections in neovascular age‐related macular degeneration (nAMD), as well as the visual development in patients followed up for one to three years in clinical practice and during different index periods.MethodsThis observational study included treatment‐naïve eyes with nAMD from the Swedish Macula Register that started treatment between 2007 and 2017, stratified by different index periods (2007–2010, 2011–2013, 2014–2015 and 2016–2017) and by follow‐up cohorts for each index period of one, two or three years (cohorts 1–3). Their intravitreal anti‐VEGF treatment was assessed by number of injections, injection intervals, visual acuity (VA) and near VA change.ResultsFrom the earliest index period 2007–2010 to the latest 2016–2017, the number of injections increased for the comparable follow‐up time; 6.2 ± 1.4 versus 8.3 ± 2.0 injections after 1 year of treatment, 4.8 ± 1.6 versus 6.7 ± 2.4 during year 2. The last injection interval was 73 ± 34 days after 1, 71 ± 33 after 2 and 67 ± 32 after 3 years of follow‐up for the index period 2014–2015. For the same period, the percentage of eyes with at least two consecutive 12–16 weeks of injection interval over 1‐, 2‐ and 3‐year follow‐up increased from 5.2%, 15.0%, to 17.5% respectively. Baseline VA for eyes indexed 2016–2017 increased and presented with 62.1 ± 13.4 letters compared with 57.7 ± 13.5 letters in 2007–2010; p < 0.0001.ConclusionsFrom the earliest to the latest index periods, the number of injections increased for the comparable follow‐up time. Accordingly, baseline VA and near VA and their outcomes improved continuously.
