Published: July 2022

PurposeConsidering both online and offline service scenarios, this study aims to explore the factors affecting doctors' intention to offer consulting services in eHealth and compare the factors between the free- and paid-service doctors. The theory of reasoned action and social exchange theory are integrated to develop the research model that conceptualizes the role of extrinsic motivations, intrinsic motivations, costs, and attitudes in doctors' behavioral intentions.Design/methodology/approachPartial least square structural equation modeling (PLS-SEM) was leveraged to analyze 326 valid sample data. To provide robust results, three non-parametric multigroup analysis (MGA) methods, including the PLS-MGA, confidence set, and permutation test approaches, were applied to detect the potential heterogeneity between the free- and paid-service doctors.FindingsThe results with overall samples reveal that anticipated rewards, anticipated associations, anticipated contribution, and perceived fee are all positively related to attitude, which in turn positively influences behavioral intention, and that perceived fee positively moderates the relationship between attitude and behavioral intention. Attitude's full mediation is also confirmed. However, results vary between the two groups of doctors. The three MGA approaches return relatively convergent results, indicating that the effects of anticipated associations and perceived fee on attitude are significantly larger for the paid-service doctors, while that of anticipated rewards is found to be significantly larger for the free-service doctors.Originality/valueeHealth, as a potential contactless alternative to face-to-face diagnoses, has recently attracted widespread attention, especially during the continued spread of COVID-19. Most existing studies have neglected the underlying heterogeneity between free- and paid-service doctors regarding their motivations to engage in online healthcare activities. This study advances the understanding of doctors' participation in eHealth by emphasizing their motivations derived from both online and offline service scenarios and comparing the differences between free- and paid-service doctors. Besides, horizontally comparing the results by applying diverse MGA approaches enriches empirical evidence for the selection of MGA approaches in PLS-SEM.
Partner selection as a control mechanism in inter-organizational relationships: a meta-model approach
Authors: Desai Hrishikesh 
Published: July 2022

Purpose
The purpose of this paper is to develop a meta-model that systematically aggregates and organizes research on “partner selection” in interorganizational relationships (IORs), which is scattered across several disciplines, to help future researchers explore various aspects of this control mechanism in a more consistent manner. This paper also aims at critically reviewing each aspect of this control mechanism examined in the prior literature and identifying important research trends.

Design/methodology/approach
This paper conducts a comprehensive review and in-depth analysis of the key theoretical and empirical research findings on partner selection in IORs by identifying 172 papers across 46 journals that specifically discuss this control mechanism. A meta-model approach is adopted to review and identify the shortcomings in extant research and provide guidance to future researchers on exploring unanswered research questions. Moreover, maps are constructed using the Luft and Shields’s (2003) approach to graphically present the causal-model forms examined in this topic area.

Findings
This meta-model shows how the research on partner selection in IORs is scattered across different disciplines, resulting in its inconsistent evolution with researchers, in many cases, not being able to effectively synthesize contributions from fields that are not their own or not closely allied. The causal-model forms also enable rapid tracing of what has been researched.

Originality/value
There has been considerable research on control mechanisms in IORs till date. However, “partner selection,” which is an important control mechanism, has received little attention and is often neglected. To the best of the author’s knowledge, this paper is the first to develop a meta-model to consolidate knowledge on this topic that is important for further advancement of research.
Towards measuring SMEs performance amid the COVID-19 outbreak: exploring the impact of integrated supply chain drivers

Published: July 2022

Purpose
This study aims to explore supply chain disruptions during the COVID-19 pandemic in the small and medium enterprise (SME) sector in Oman. This study analyzes the impact on selected supply chain drivers – facilities, inventory, transportation and sourcing. It further intends to explore whether the supply chain challenges faced by the SME sector in Oman impact their overall performance.

Design/methodology/approach
This study follows the quantitative technique of structural equation modeling to examine the proposed hypotheses. Data were collected electronically from SME managers/owners/entrepreneurs. All items were adopted and measured using a five-point Likert scale. One hundred and four complete and usable responses were received and considered.

Findings
The data was analyzed using SPSS and PLS statistical software. The model has been supported empirically, and the results showed a significant relationship between supply chain drivers and SMEs’ overall performance in Oman, except for supply chain inventory. The results have demonstrated that the COVID-19 pandemic has affected the SMEs’ supply chain drivers in Oman and, consequently, their overall performance.

Practical implications
The results of this research can drive the development and implementation of a supply chain management strategy. This research will help policymakers induce the performance of SMEs affected by the COVID-19 pandemic. It would further enhance strategic sourcing and supplier performance considering the developed practices associated with the resource-based view.

Originality/value
The originality of the current study lies in its ability to empirically test two models within the Omani SMEs context while considering the supply chain drivers as a single variable or dividing it into four separate independent variables. This study would provide a preview for scholars for such empirical investigation and serve as a reference for policymakers and practitioners to maintain a management system of crises that may protect the SME supply chain drivers.
Boosting innovation through gender and ethnic diversity in management teams
Authors: Quintana-García Cristina , Marchante-Lara Macarena , Benavides-Chicón Carlos G. 
Published: July 2022

PurposeThis study investigates the link between diversity in management and CEO positions and firm innovation. The purpose of this paper is to examine the effect that women and ethnic diversity in management and CEO positions have on the development of outstanding innovation in firms.Design/methodology/approachThis paper conducts an empirical analysis to investigate these relationships over time using a large panel database of 1,345 publicly US traded firms.FindingsResults revealed that gender and ethnic diversity at all levels of management exhibited a robust positive association with superior innovation competence. This finding remains robust when alternative proxies for innovation are employed. In contrast, the authors found that women and ethnic minorities at the CEO level had no significant influence.Originality/valueConsidering an output measure of innovation, the authors explore the effect of gender and ethnic minority groups in management positions as well as at the CEO level, rather than focusing only on top management teams or board of directors. The authors offer new practical insights regarding the manager selection process that are also useful to support public policy initiatives.

PurposeThis study aims to examine whether the sustainability committee, a specialized governance mechanism for environmental and social issues, is related to environmental performance. Specifically, the authors consider the presence and effectiveness of the sustainability committee.Design/methodology/approachUsing a sample of Australian firms (2002–2016), the presence of a sustainability committee and sustainability committee effectiveness (consisting of 12 sustainability committee characteristics) are examined. Firms’ environmental performance is measured by Thomson Reuters Asset4 ratings.FindingsThe authors confirm prior findings of a positive relationship between the presence of a sustainability committee and the firm’s environmental performance. More importantly, sustainability committee effectiveness is found to be positively associated with environmental performance, indicating the active role that the composition and function of the sustainability committee plays in enhancing environmental performance.Practical implicationsThe findings are of interest to directors and managers who are interested in improving firms’ environmental performance, in addition to investors and regulators who are concerned about environmental performance.Originality/valueThis study meaningfully expands the extant literature that studies the sustainability committee in at least three ways. First, the authors evidence the effect of an unexplored dimension of committee heterogeneity (sustainability committee effectiveness) by hand-collecting detailed information of sustainability committee members. Second, the authors distinguish from prior studies, in that the authors test the direct relationship between sustainability committee effectiveness and environmental performance. Third, by adopting different robustness tests of endogeneity along with sampling firms in various industries over 15 years, the authors offer more compelling and more comprehensive evidence in this regard. Broadly, the authors enrich the literature on corporate governance and environmental performance.

Abstract

Bacterial symbionts can play a key role in the interactions between trophic levels. Certain symbionts are known to confer protection against natural enemies of their arthropod hosts. However, whether natural enemies evolve and adapt to prey symbionts is not well understood.

In this study, we found that a free‐living strain of aphid symbiont Serratia symbiotica, SsMj, was the most discriminative biomarker of the aphid feeding in the microbiota of aphidophagous (aphid‐feeding) ladybirds. Moreover, SsMj persisted in the digestive tract of starved ladybirds and did not decay together with ingested aphid materials, suggesting horizontal transmission across trophic levels.

We further found that SsMj did not necessarily exhibit a negative impact on aphidophagous ladybirds of the Coccinellini tribe in contrast with other, non‐aphidophagous, ladybirds. First, starvation did not significantly change SsMj relative abundance or alpha microbiota diversity of an aphidophagous ladybird. Second, diets containing SsMj did not decrease the performance of the aphidophagous ladybirds. Third, infection with SsMj through injection had a minor impact on the survival of aphidophagous ladybirds.

Together, our evidence suggests that the aphid symbiont S. symbiotica can be horizontally transmitted to ladybird predators. At the same time, the group of ladybirds that have adapted to feeding on aphids have also evolved to establish a nearly neutral relationship with S. symbiotica, suggesting adaptation to a prey symbiont.

Developing a morphological awareness intervention through inquiry‐based learning
Authors: Mulder Evelien , van der Graaf Joep , Verhagen Véronique , Mos Maria , Droop Mienke 
Published: July 2022

Secondary school students are increasingly exposed to texts containing morphologically complex words. Morphological knowledge may help with understanding those words. Appropriate educational materials to teach morphological awareness (MA) are scarce. A design‐based approach was used to develop an MA‐intervention for Dutch secondary school students. We (1) analysed the aforementioned problem through semi‐structured discussions with teachers and a review of previous MA‐intervention research; (2) developed a prototype of an MA‐intervention in collaboration with teachers; (3) evaluated materials from Step 2 quantitatively through a pilot study with seventh grade students (N = 60) and qualitatively through a semi‐structured discussion with teacher educators (N = 4); and (4) reflected on the proposed design principles. Insights obtained from teachers and the literature were implemented in our MA‐intervention. Students' performance was related to a measure of general language proficiency. Finally, teachers, students, and teacher educators pointed out several strengths and weaknesses of the intervention. The present study highlights the importance of the following design principles: focus on the patterns in morphology in order for students to explicate their morphological knowledge, suitability of the intervention for students with varying levels of language proficiency, and availability of training and background information about MA for teachers. Collaborating with teachers provided indispensable insights into students' needs, knowledge of MA, how MA‐interventions can be implemented and matched to teachers' pedagogical expertise and experience.
Group processes and interoperability: A longitudinal case study analysis of the UK's civil contingency response to Covid‐19

Published: July 2022

AbstractOur case study explored a Local Resilience Forum's (LRF) civil contingency response to COVID‐19 in the United Kingdom. We undertook 19 semistructured ethnographic longitudinal interviews, between March 25, 2020 and February 17, 2021, with a Director of a Civil Contingencies Unit and a Chief Fire Officer who both played key roles within their LRF. Within these interviews, we focused on their strategic level decision‐making and how their relationship with national government impacted on local processes and outcomes. Using a form of grounded theory, our data describe the chronological evolution of an increasingly effective localized approach toward outbreak control and a growing resilience in dealing with concurrent emergency incidents. However, we also highlight how national government organizations imposed central control on aspects of the response in ways that undermined or misaligned with local preparedness. Thus, during emergencies, central governments can undermine the principle of subsidiarity and damage the ways in which LRFs can help scaffold local resilience. Our work contributes to the theoretical understanding of the social psychological factors that can shape the behaviour of responder agencies during a prolonged crisis. In particular, the implications of our analysis for advancing our conceptual understanding of strategic decision‐making during emergencies are discussed.
Observations of interference competition between the introduced black rat and native marsupial gliders in Australia
Authors: McGregor Jess , Field Jed , McLean Chris , Beranek Chad , Gould John 
Published: July 2022

AbstractIntroduced rodents, particularly the black rat (Rattus rattus), have caused serious ecological impacts due to their ability to interact with native species as both predators, and by eliciting competitive pressure. However, impacts of black rats upon many Australian mammals have yet to be determined, particularly when those mammals are arboreal. Here, we present novel observations in the form of camera trap footage and photographs of interspecific competition between the introduced black rat and two species of arboreal gliding marsupial (sugar gliders (Petaurus breviceps) and squirrel gliders (Petaurus norfolcensis)) in urban bushland reserves in New South Wales, Australia. Gliders were found to flee or were prevented from exploiting food resources due to antagonistic posturing and physical attacks by black rats. While interspecific aggression and interference competition between black rats and native mammal species has been demonstrated previously, this appears to be the first observation of such interactions for Australian gliders. Our findings may have implications for the future management of glider populations in urban bushland where they co‐occur with rats; however, further research needs to be undertaken to determine the extent of this potential threat.

Published: July 2022

AbstractThis study aimed at investigating the dietary composition of rodents in the Ukaguru Mountains, Tanzania. Micro‐histological analysis of the stomach contents of rodents collected from various habitats was carried out. In the diet of Mastomys natalensis, Lemniscomys rosalia and Mus triton, seed/grain showed greater importance (>35%, >55% and 60% respectively), whereas for Lophuromys kilonzoi, plant materials were more important (>55%) than other categories. Seed/grains were more important (>20%) in the diet of Praomys delectorum, while plant materials were more important (>45%) in the diet of forest‐dwelling L. kilonzoi. Food diversity for rodents in farmland was relatively low compared with forest‐dwelling rodents. Our results indicated that the relatively low niche breadth observed in rodents caught in farms could be attributed to the major contribution of seed/grains to their diet while forest‐dwelling rodents showed greater food diversity owing to the more heterogeneous and stable nature of forests compared with farms. The abundance of food resources in both habitats would have permitted coexistence of rodent species.

Published: July 2022

AbstractIntroductionPreeclampsia (PE) is a heterogeneous disorder and research to date has principally focused on maternal factors. In this study, however, we considered the associations between background factors and preeclampsia in men who fathered preeclamptic and non‐preeclamptic pregnancies.Material and methodsFrom 2008 to 2011, participants in the Finnish Genetics of Pre‐eclampsia Consortium (FINNPEC) cohort completed a questionnaire on their background information. Questionnaire data were available from 586 men who had fathered a preeclamptic pregnancy (PE fathers) and 660 control men who had fathered a non‐preeclamptic pregnancy. Two different control groups were established: Group 1: healthy controls (n = 457), which consisted of fathers whose current partners were healthy women with uncomplicated pregnancies; Group 2: other controls (n = 203), which also included fathers whose current partners had other pregnancy complications.ResultsThe PE fathers more often reported preeclampsia in a previously fathered pregnancy (p < 0.05 for all). The PE and control fathers were similar in age, body mass index, smoking, and preexisting medical conditions. There were no differences in the socioeconomic background or health history of the PE and control fathers or their parents.ConclusionsIn the FINNPEC study cohort, the occurrence of preeclampsia in a previously fathered pregnancy was more common among the men who had fathered a preeclamptic pregnancy; other paternal phenotypic and lifestyle characteristics did not play a significant role in preeclampsia susceptibility of their partners.

AbstractBackgroundThe number of people with intellectual disabilities and associated mental illness has increased considerably in recent years. This population presents greater obstacles than their peers without mental health problems in accessing education, leisure, and health services. This, conditions their quality of life (QoL) and makes them one of the most vulnerable groups in society.MethodsThis study seeks to know the level of QoL of 181 people with intellectual disabilities and mental health problems between the ages of 35 and 75, based on the perceptions of the professionals who work with them in different disability care services in Chile. The data were collected with the FUMAT scale.FindingsThe dimensions of self‐determination and personal development obtained the lowest scores. In addition, living in rural settings, receiving regular support, or being a man was associated with a better QoL.ConclusionsIt would be desirable to increase the frequency with which certain supports aimed at the population with intellectual disabilities and mental health problems are provided. Likewise, the exercise of informed and meaningful choices must be encouraged.

Published: July 2022

Background and PurposeChondroitin sulfate proteoglycan (CSPG) constitutes the neurogenic niche in the hippocampus. The reduction of hippocampal neurogenesis is involved in ageing‐related cognitive decline and dementia. The purpose of this study is to find candidates that improve cognitive function by analysing the effects of memantine (MEM), a therapeutic agent for Alzheimer's disease, on CSPG and adult hippocampal neurogenesis.Experimental ApproachThe effects of MEM on neurogenesis‐related cells and CSPG content were assessed in the hippocampus of middle‐aged mice. The MEM‐induced alterations in gene expressions of neurotrophins and enzymes associated with biosynthesis and degradation of CSPG in the hippocampus also were measured. The effects of MEM on cognitive function were estimated using a behavioural test battery. The same set of behavioural tests was applied to evaluate the effects of pharmacological depletion of CSPG in the hippocampus.Key ResultsThe densities of newborn granule cells and content of CSPG in the hippocampus were increased by MEM. The expression levels of the enzyme responsible for the biosynthesis CSPG were increased by MEM. The neurotrophin‐related molecules were activated by MEM. Short‐ and long‐term memory performance was improved by MEM. Pharmacological depletion of CSPG impairs the effects of MEM on cognitive improvement in middle‐aged mice.Conclusion and ImplicationsMEM regulates the biosynthesis and degradation of CSPG, which may underlie the improvement of cognitive function via the promotion of adult hippocampal neurogenesis. These results imply that CSPG‐related enzymes potentially may be attractive candidates for the treatment of ageing‐related cognitive decline.
