Lesson study as a vehicle for improving SEND teachers’ teaching skills
Authors: Holmqvist Mona 
Published: June 2020

PurposeCollaborative professional development for inclusive teaching is a limited area of research, although there is an extensive need for special educational needs and disabilities (SEND) teachers. Research findings of how teachers’ professional development can contribute to support the development of powerful learning situations for all students are presented in this special issue. The aim is to contribute to the knowledge of how the use of lesson study can develop teachers’ capabilities to offer high-quality education for students with SEND.Design/methodology/approachThe guest editor presents each of the papers and introduces key themes and concepts.FindingsThe collection of papers is divided into two themes; the first has a focus on lesson study used by teacher educators during SEND in-service training. In this theme, the teachers are the students who are studying different fields of SEND, supported by teacher educators. The second theme studies different forms of lesson studies carried out by researchers and teachers in the collaboration focused aspects of content that are of importance for students in SEND.Research limitations/implicationsThe papers focus on areas of education with a limited research tradition, and as a result, the studies may be seen as starting points for further research. The results so far lack generalisability. Therefore, the researchers have to test the findings further under different conditions and with wider groups of teachers and students.Practical implicationsThe results of the papers can be used to develop both SEND teacher education, and collaborative professional development for in-service SEND teachers. This issue will, therefore, be of interest to school and system leaders.Originality/valueThe papers contribute initial findings from an under-researched area and also combine lesson study with methods and designs not previously explored.
How to design fashion retail's virtual reality platforms
Authors: Xue Liangchao , Parker Christopher J. , Hart Cathy 
Published: June 2020

PurposeHigh-street fashion retail faces an uncertain future because of fluctuating consumer shopping habits. To revive fashion retailers, adopting disruptive technologies such as virtual reality (VR) becomes important to offer highly valued consumer experiences. Yet v-commerce designers still lack sufficient guidance to create effective retail environments. This paper establishes the v-commerce experience that targets fashion consumers’ desire and presents 13 specific design guidelines.Design/methodology/approachIn this study, 22 participants, 20 consumers and two VR developers were interviewed regarding attitudes towards VR, motivation to shop through v-commerce and the moderating variables that influence virtual environment perceptions.FindingsConsumers expect a vivid shopping environment with authentic product features instead of the more common simulated environment. Hedonically motivated consumers are more open to v-commerce than utilitarian consumers and consumers aged 18–34 years regard interactivity, personalisation and social networking as critical to offer a cost-efficient shopping experience.Research limitations/implicationsThis paper explored the ways v-commerce delivers creative experiences to facilitate consumer purchase behaviour, contributing to the high street's regeneration. Yet consumers have too high expectations of lifelike interaction in v-commerce, which is beyond contemporary VR's capabilities. Future research should focus on developing authenticity of v-commerce environments, i.e. vivid interaction with product and people.Originality/valueThis paper establishes the fundamental design rules for v-commerce platforms, enabling designers to create effective retail environments, sympathetic to the consumer's cognitive desires.

PurposeTo identify transitional palliative care (TPC) interventions for older adults with non-malignant chronic diseases and complex conditions.Design/methodology/approachA systematic review of the literature was conducted. CINAHL, Cochrane Library, Embase and Pubmed databases were searched for studies reporting TPC interventions for older adults, published between 2002 and 2019. The Crowe Critical Appraisal Tool was used for quality appraisal.FindingsA total of six studies were included. Outcomes related to TPC interventions were grouped into three categories: healthcare system-related outcomes (rehospitalisation, length of stay [LOS] and emergency department [ED] visits), patient-related outcomes and family/carer important outcomes. Overall, TPC interventions were associated with lower readmission rates and LOS, improved quality of life and better decision-making concerning hospice care among families. Outcomes for ED visits were unclear.Research limitations/implicationsPositive outcomes related to healthcare services (including readmissions and LOS), patients (quality of life) and families (decision-making) were reported. However, the number of studies supporting the evidence were limited.Originality/valueStudies examining the effectiveness of existing care models to support transitions for those in need of palliative care are limited. This systematic literature review identified and appraised interventions aimed at improving transitions to palliative care in older adults with advanced non-malignant diseases or frailty.
The impact of social media use for communication and social exchange relationship on employee performance
Authors: Chen Xiayu , Wei Shaobo 
Published: June 2020

PurposeThe purpose of this paper is to investigate the underlying mechanisms through which social media use for vertical and horizontal communication enhance employee performance.Design/methodology/approachTo test the research model, the authors conducted a questionnaire survey in China. The authors used a customer panel database provided by a marketing research firm in China to identify appropriate respondents. Finally, the authors received 243 valid responses.FindingsThe authors find that social media use for vertical communication (SMUVC) is positively related to leader-member exchange (LMX) and social media use for horizontal communication (SMUHC) is positively related to team-member exchange (TMX). LMX and TMX are positively related to employee performance. LMX is positively associated with TMX. Besides, task complexity positively moderates the relationship between LMX and employee performance, while it negatively moderates the relationship between TMX and employee performance.Originality/valueFirst, it adds to the literature by investigating the underlying mechanisms of how social media use for communication influences job performance. By identifying LMX and TMX as the underlying mechanisms, the authors make comprehensive considerations of how the vertical and horizontal relationships link the effect of social media use for communication on employee performance. Second, despite the growing evidence demonstrates that high-quality LMX and TMX can individually contribute to employee job performance, little research has considered both LMX and TMX relationships simultaneously and their effects on job performance. Finally, by establishing task complexity as a key moderator on the relationships between LMX and TMX and job performance, the study could explain the inconsistent findings in the literature that the effects of LMX and TMX are significant in some studies yet not significant in other studies.
Leadership styles and employees’ work outcomes in nonprofit organizations: the role of work engagement
Authors: Aboramadan Mohammed , Dahleez Khalid Abed 
Published: June 2020

PurposeThis study aims to investigate the effects of transformational and transactional leaders’ behaviors on employees’ affective commitment and organizational citizenship behavior in the context of nonprofit organizations (NPOs). Additionally, this study attempts to examine the role of work engagement, as an intervening mechanism as work engagement in NPOs has been empirically neglected (Park et al., 2018).Design/methodology/approachData were conducted from 400 employees working in Italian NPOs in the North of Italy. For verifying the hypotheses of this study, structural equation modeling techniques were implemented.FindingsIt was found that both transformational and transactional leaderships influenced positively affective commitment and organizational citizenship behavior, and work engagement was revealed to have significant positive mediating effects on the relationship between the variables examined in this study.Practical implicationsThe results of this study may be beneficial to leaders and supervisors of NPOs, specifically regarding the influence of the leaders’ behaviors on the employees’ outcomes.Originality/valueDue to the limited number of studies conducted on leadership in nonprofit organizations, this study theoretically and empirically contributes to the leadership literature as it is the first study to investigate the two styles of leadership on work-related outcomes via work engagement in the nonprofit sector.
Trade-off between value creation and value appropriation?
Authors: Silveira Cleo Schmitt , Oliveira Marta Olivia Rovedder de , Heldt Rodrigo , Luce Fernando Bins 
Published: June 2020

PurposeManagers face the challenge of balancing resources needed to support value creation and value appropriation. In this study the authors analyze the impacts of innovation investments (i.e. value creation: VC) on advertising expenditures (i.e. value appropriation: VA), and vice versa, and verify the effects of these options on short- and long-term performance.Design/methodology/approachThe effects of these two activities on short- and long-term performance were analyzed observing a panel of 4,090 companies of Standard and Poor's Compustat database from a 40-year period. The authors adopted the panel vector autoregressive (VAR) approach, using the generalized method of moments (GMM).FindingsAlthough there is a trade-off between the strategic emphases on creating and appropriating value, there is also a synergy between them. The results from the impulse response functions support the argument for a virtuous business circle: companies that choose to intensify their investments in R&D tend to increase advertising expenditures, and vice versa.Practical implicationsManagers, rather than having to deal with a trade-off between allocating resources either on VC or VA activities, can capitalize on synergetic benefits resulting from the interaction among them.Originality/valueThe relationship between the VC and VA activities transcends the trade-off imposed by resource restrictions, since the interaction between them creates additional benefits afforded by the synergy of these activities.

Published: June 2020

SummaryDiplonemids are a group of highly diverse and abundant marine microeukaryotes that belong to the phylum Euglenozoa and form a sister clade to the well‐studied, mostly parasitic kinetoplastids. Very little is known about the biology of diplonemids, as few species have been formally described and just one, Diplonema papillatum, has been studied to a decent extent at the molecular level. Following up on our previous results showing stable but random integration of delivered extraneous DNA, we demonstrate here homologous recombination in D. papillatum. Targeting various constructs to the intended position in the nuclear genome was successful when 5′ and 3′ homologous regions longer than 1 kbp were used, achieving N‐terminal tagging with mCherry and gene replacement of α‐ and β‐tubulins. For more convenient genetic manipulation, we designed a modular plasmid, pDP002, which bears a protein‐A tag and used it to generate and express a C‐terminally tagged mitoribosomal protein. Lastly, we developed an improved transformation protocol for broader applicability across laboratories. Our robust methodology allows the replacement, integration as well as endogenous tagging of D. papillatum genes, thus opening the door to functional studies in this species and establishing a basic toolkit for reverse genetics of diplonemids in general.
Identification of an extracytoplasmic function sigma factor that facilitates c‐type cytochrome maturation and current generation under electrolyte‐flow conditions in Shewanella oneidensisMR‐1

Published: June 2020

SummaryShewanella oneidensis MR‐1 was cultured on electrodes in electrochemical flow cells (EFCs), and transcriptome profiles of electrode‐attached cells grown under electrolyte‐flow conditions were compared with those under static (nonflow) conditions. Results revealed that, along with genes related to c‐type cytochrome maturation (e.g., dsbD), the SO_3096 gene encoding a putative extracytoplasmic function (ECF) sigma factor was significantly upregulated under electrolyte‐flow conditions. Compared to wild‐type MR‐1 (WT), an SO_3096‐deletion mutant (∆SO_3096) showed impaired biofilm formation and decreased current generation in EFCs, suggesting that SO_3096 plays critical roles in the interaction of MR‐1 cells with electrodes under electrolyte‐flow conditions. We also compared transcriptome profiles of WT and ∆SO_3096 grown in EFCs, confirming that many genes upregulated under the electrolyte‐flow conditions, including dsbD, are regulated by SO_3096. LacZ reporter assays showed that transcription from a promoter upstream of dsbD is activated by SO_3096. Measurement of current generated by a dsbD‐deletion mutant revealed that this gene is essential for the transfer of electrons to electrodes. These results indicate that the SO_3096 gene product facilitates c‐type cytochrome maturation and current generation under electrolyte‐flow conditions. The results also offer ecophysiological insights into how Shewanella regulates extracellular electron transfer to solid surfaces in the natural environment.

Published: June 2020

AbstractForensic science uses scientific methods to help the scientists who study evidence to assist in the solving of crimes. Coleoptera is the most diverse and speciose group of insects that have an important role in many scientific fields especially forensic entomology. In addition, it is difficult to morphologically identify and discriminate between them. In the present study, the molecular analysis using mitochondrial DNA information was conducted to swiftly and accurately identify the recovered Coleoptera species. A molecular identification method involving a 221‐bp segment of the 16 s ribosomal RNA (16 s rRNA) gene from three beetle species, collected from a rabbit carcass, was evaluated. The analysis with maximum likelihood method recovered a generally well supported phylogeny, with most currently accepted taxa and species groups as monophyletic. These results will be instrumental for the implementation of the Saudian database of forensically relevant beetles.

Published: June 2020

BackgroundAngiotensin‐converting enzyme inhibitor (ACE‐I) and angiotensin‐receptor blocker (ARB) users may be associated with increased mortality in patients with post‐operative acute kidney injury (AKI), but data are limited. We studied whether users of ACE‐I/ARBs with AKI after colorectal cancer surgery (CRC) were associated with increased 1‐year mortality after AKI.MethodsThis population‐based cohort study in Northern Denmark included patients with AKI within 7 days after CRC surgery during 2005‐2014. From reimbursed prescriptions, patients were classified as ACE‐I/ARB current, former, or non‐users. We computed the cumulative 30‐day and 1‐year mortality after AKI with 95% confidence intervals (95% CI) using the Kaplan‐Meier method (1—survival function). Hazard ratios (HRs) comparing mortality in current and former users with non‐users were computed by Cox proportional hazards regression analyses, controlling for potential confounders.ResultsWe identified 10 713 CRC surgery patients. A total of 2000 patients had AKI and were included. Thirty‐day mortality was 16.5% (95% CI 13.7‐19.8), 16.2% (95% CI 11.3‐22.8), and 13.4% (95% CI 11.6‐15.4) for current, former, and non‐users. Adjusted HR was 1.26 (95% CI 0.96‐1.65) and 1.19 (95% CI 0.78‐1.82) for current and former users compared with non‐users. One‐year mortality rates were 26.4% (95% CI 22.9‐30.4), 29.8% (95% CI 23.2‐37.8), and 24.7% (95% CI 22.4‐27.2) in current, former, and non‐users. Compared with non‐users, the adjusted 1‐year HR for death in current and former users were 1.29 (95% CI 0.96‐1.73) and 1.11 (95% CI 0.91‐1.35).ConclusionBased on our findings, current users of ACE‐I/ARB may possibly have a small increase in mortality rate in the year after post‐operative AKI, although the degree of certainty is low.
Board‐level ethics committees in large European firms

Published: June 2020

AbstractAfter the approval of a code of ethics, the creation of a permanent board‐level ethics committee is the next step in the institutionalization of business ethics. This study explores how the board's structure and demographic characteristics explain the decision to form an ethics committee. The analysis is based on the constituents of the Standard and Poor's Europe 350 index. Consistent with our hypotheses, we find that ethics committees are more likely to be found in firms with a lower presence of executive directors and of directors holding MBA degrees. However, we also observe that boards chaired by executive directors seem to favor the creation of an ethics committee. Additionally, as we had anticipated, firms with stronger agency conflicts seem to be more willing to create committees. The analysis conducted with segmented samples reveals that the model has greater explanatory power when applied to firms from common‐law and French civil‐law countries than when applied to firms from the German–Scandinavian civil‐law area. Finally, our results indicate that a firm's country of origin is a more influential factor in explaining the decision to create an ethics committee than the industry to which it belongs or even the magnitude of its agency conflicts.

AbstractIntroductionWe aimed to evaluate the association between PNPLA3 polymorphism and post‐liver transplantation (LT) outcomes related to alcohol relapse (AR).MethodWe retrospectively analyzed data from patients receiving LT for alcoholic liver disease (ALD) from 04/2014 to 12/2017. Liver‐related clinical outcomes were assessed by the gamma‐glutamyltransferase (GGT) level and alcohol‐related liver failure (ARLF). Genotyping was performed using prospectively collected DNA samples in both donors and recipients.ResultsA total of 83 recipients were enrolled. Post‐LT AR occurred in 31 patients (37.3%). Thirty‐one patients (14 AR, 9 abstainers) showed elevated GGT levels, and 3 AR patients experienced ARLF. In the multivariate analysis, rs738409 G allele carrier and heavy drinking (HRAR score ≥ 4) were independent risk factors for elevated GGT levels (odds ratio [OR] = 8.69, P < .01; OR = 13.07, P = .01) and ARLF (OR = 4.52, P = .04; OR = 19.62, P = .03). Among 15 heavy AR patients, being an rs738409 G allele carrier was related to GGT elevation (P = .03) and ARLF (P = .04), but it was not related to GGT elevation in mild drinkers (n = 16) or abstainers (n = 52).ConclusionPNPLA3 polymorphism of the recipient genotype can independently affect the post‐LT prognosis of LT patients for ALD, especially in heavy AR patients. Therefore, strong abstinence education is recommended in patients with this single nucleotide polymorphism.

AbstractIntroduction and AimsPregabalin is a gamma‐aminobutyric acid analogue registered and subsidised for the treatment of neuropathic pain in Australia. Despite pre‐clinical evidence of low abuse potential, there are increasing reports of extramedical use and overdose deaths involving pregabalin. This study aimed to describe patterns of pregabalin use among an Australian sample of people who inject drugs (PWID) and identify sociodemographic, substance use and mental/physical health correlates of prescribed and non‐prescribed use.Design and MethodsData were obtained from the 2018 Illicit Drug Reporting System, comprising a cross‐sectional sample of 905 PWID recruited from Australian capital cities. Multinomial logistic regression was used to identify correlates of past 6‐month prescribed and non‐prescribed pregabalin use.ResultsOne‐quarter (25%) of participants reported any past 6‐month pregabalin use, with 10% reporting prescribed use and 15% non‐prescribed use. Past 6‐month use of prescribed benzodiazepines and non‐prescribed pharmaceutical opioids were associated with both prescribed and non‐prescribed pregabalin use compared to no recent pregabalin use. Pain/discomfort on the day of interview was significantly associated with prescribed pregabalin use. Recent use of non‐prescribed benzodiazepines and illicit stimulants and past year non‐fatal overdose were significantly associated with non‐prescribed pregabalin use (compared to no recent pregabalin use).Discussion and ConclusionsPregabalin use was relatively common among an Australian sample of PWID. Benzodiazepine and pharmaceutical opioid use were positively correlated with both prescribed and non‐prescribed pregabalin use, suggesting that education campaigns regarding the risks of harm associated with concomitant use of these substances are warranted (targeting both health professionals and consumers).
