Effect of repetitive peripheral magnetic stimulation combined with motor imagery on the corticospinal excitability of antagonist muscles
Authors: Asao Akihiko , Hoshino Yuma , Nomura Tomonori , Shibuya Kenichi 
Published: May 2021

Objective
Repetitive peripheral magnetic stimulation (rPMS) combined with motor imagery facilitates the corticospinal excitability of the agonist muscles. However, the effects of rPMS combined with motor imagery on the corticospinal excitability of the antagonist muscles are unclear. This is an important aspect for applying rPMS in neurorehabilitation for sensorimotor dysfunction. Therefore, we investigated the real-time changes of corticospinal excitability of antagonist muscles during rPMS combined with motor imagery.

Methods
Fourteen healthy volunteers underwent four different experimental conditions: rest, rPMS, motor imagery, and rPMS combined with motor imagery (rPMS + motor imagery). In the rPMS and rPMS + motor imagery conditions, rPMS (25 Hz, 1600 ms/train, 1.5× of the motor threshold) was delivered to the dorsal side of the forearm. In motor imagery and rPMS + motor imagery, the participant imagined wrist extension movements. Transcranial magnetic stimulation was delivered to record motor-evoked potentials of the antagonist muscle during experimental interventions.

Results
The motor-evoked potential (normalized by rest condition) values indicated no difference between rPMS, motor imagery, and rPMS + motor imagery.

Conclusion
These results suggest that rPMS combined with motor imagery has no effect on the corticospinal excitability of the antagonist muscles and highlight the importance of investigating the effects of rPMS combined with motor imagery at the spinal level.

AbstractObjectiveTraditional pairwise meta-analyses indicated that nuts consumption can improve blood pressure. We iamed to determine the dose-dependent effect of nuts on systolic (SBP) and diastolic blood pressure (DBP) in adults.MethodsA systematic search was undertaken in PubMed, Scopus, and ISI Web of Science till March 2021. Randomized controlled trials (RCT) evaluating the effects of nuts on SBP and DBP in adults were included. We estimated change in blood pressure for each 20 g/d increment in nut consumption in each trial and then, calculated mean difference (MD) and 95%CI using a random-effects model. We estimated dose-dependent effect using a dose-response meta-analysis of differences in means. The certainty of evidence was rated using the GRADE instrument, with the minimal clinically important difference being considered 2 mmHg.ResultsA total of 31 RCTs with 2784 participants were included. Each 20 g/d increase in nut consumption reduced SBP (MD: -0.50 mmHg, 95%CI: -0.79, -0.21; I2= 12%, n = 31; GRADE = moderate certainty) and DBP (MD: -0.23 mmHg, 95%CI: -0.38, -0.08; I2= 0%, n = 31; GRADE = moderate certainty). The effect of nuts on SBP was more evident in patients with type 2 diabetes (MD: -1.31, 95%CI: -2.55, -0.05; I2= 31%, n = 6). The results were robust in the subgroup of trials with low risk of bias. Levels of SBP decreased proportionally with the increase in nuts consumption up to 40 g/d (MD40g/d: -1.60, 95%CI: -2.63, -0.58), and then appeared to plateau with a slight upward curve. A linear dose-dependent reduction was seen for DBP, with the greatest reduction at 80 g/d (MD80g/d: -0.80, 95%CI: -1.55, -0.04).ConclusionsThe available evidence provides a good indication that nut consumption can result in a small improvement in blood pressure in adults. Well-designed trials are needed to confirm the findings in long term follow-up.
Sex matters: effects of sex and mating in the presence and absence of a protective microbe
Authors: Kloock Anke , Peters Lena , Rafaluk-Mohr Charlotte 
Published: May 2021

AbstractIn most animals, female investment in offspring production is greater than for males. Lifetime reproductive success (LRS) is predicted to be optimised in females through extended lifespans to maximise reproductive events. Extended lifespan can be achieved through increased investment in immunity. Males, however, maximise lifetime reproductive success by obtaining as many matings as possible. Microbe-mediated protection (MMP) is known to affect both immunity and reproduction, but whether the two sexes respond differently to the provision of MMP remains to be explored. Here, we investigated the sex-specific differences in host life history traits between female and male Caenorhabditis elegans following pathogenic infection with Staphylococcus aureus with or without MMP by Enterococcus faecalis. Overall, female survival decreased with increased mating. With MMP, females increased investment into offspring production, while males displayed higher behavioural activity. These results highlight the different strategies employed by the two sexes under pathogen infection with and without MMP.

Published: May 2021

PurposeCircular economy denotes future sustainability that allows optimum utilization of resources. In the present era of technology, plenty of innovations are happening across the world, and digital manufacturing is one of such innovations. However, there are several barriers which are impeding adoption of digital manufacturing in circular economy environment. The study explores the barriers of digital manufacturing initiatives in a circular economy and develops a methodological model to prioritize the identified challenges for automotive parts manufacturing industry.Design/methodology/approachSeven categories of challenges namely process, human resources, financial, collaboration, technological, security and leadership challenges were identified from literature and further validated with subsequent discussions with experts from the industry. The study is conducted in two phases, where in the first phase, the Decision-Making Trial and Evaluation Laboratory (DEMATEL) technique is used to define the priority and importance of seven categories of challenges. In second phase, the barriers are ranked using a Fuzzy Performance Important Index (FPII), taking into account contextual factors associated with the challenges and linked barriers, to determine the extent to which they impede the adoption of digital manufacturing in the sample automotive parts manufacturing company.FindingsThe “risk of data security and information privacy in connection with use of external data and protecting customer data” appeared as the most significant barrier to digital manufacturing in circular economy. Furthermore, technological challenges emerged as the most significant category of challenges followed by financial challenges in adoption of digital manufacturing in circular economy.Practical implicationsIdentification of the identified barriers and understanding the interrelationships will lead to easier adoption of digital manufacturing in circular economy.Originality/valueDespite all the potential benefits of implementing Industry 4.0 technologies in manufacturing industries, the adoption thereof is still in nascent phase with significant challenges yet to be overcome to accelerate the pace of adoption. Hence, this study explores the barriers preventing companies from adopting and benefiting from digital manufacturing initiatives and further develops a methodological model.

Design/methodology/approach
In this paper, the authors reflect on the advantages of school-based research designs for studying gang affiliated youth, primarily contrasting the data derived from school-based designs to official data from police.

Findings
xSpecifically, the authors discuss the key advantages of school-based survey research, identify concerns that can arise from such designs and offer recommendations as to how to mitigate such concerns.

Originality/value
This paper provides a discussion on the utility of gang-related research and guidance on addressing potential limitations.
From Industry 4.0 to Education 4.0: acceptance and use of videoconferencing applications in higher education of Oman
Authors: Jain Vishal , Jain Parul 
Published: May 2021

PurposeThe present paper is an attempt to study Education 4.0 supported by Industry 4.0 tools and techniques. The main purpose of the study is to examine the acceptance and use of one of the internet of things (IoT)-based learning management systems, i.e. videoconferencing application (Google Meet, Microsoft Teams, Zoom, GoToMeeting, WebEx), by academicians of higher education using the unified theory of acceptance and use of technology (UTAUT) model.Design/methodology/approachThe study comprises 218 responses of academicians associated with higher education in the Sultanate of Oman. Descriptive and factor analysis of the collected data are employed using SPSS-26. Further, using Amos-21, the fit and validity indices of the measurement model are computed. Various relationships of the UTAUT structural model along with moderation effects of gender and nationality are tested.FindingsThe results suggest that performance expectancy, effort expectancy and social influence significantly predict behavioral intention. In turn, behavioral intention and facilitating conditions also significantly predict the use behavior of academicians for videoconferencing in higher education. Finally, gender moderates two out of four UTAUT relations, but nationality does not moderate any of these relations.Originality/valueA lot of prior studies investigate several models to use technology-enabled pedagogy from educators' or students' perspectives. There are very limited studies that examine IoT-based learning tools within the UTAUT environment. Additionally, no study is available that considers UTAUT relations for the use of videoconferencing in higher education. Also, in the present study, one more moderator, i.e. nationality, is tested.

Authors: Harris Brigitte , Childs Elizabeth Anne , Axe Jo , Gorley Charlotte 
Published: May 2021

PurposeThis project engaged faculty, students, alumni and staff in re-visioning their university's learning, teaching and research framework. An extensive consultation process allowed participants to explore, discuss and critically reflect on effective practice.Design/methodology/approachThis action research project provided a process for university community members to engage in practice conversations. In phase 1, focus groups and campus community discussions elicited the diverse perspectives of the community. The design-thinking process of discovery, ideation and prototyping aligned with the action research cycles to help a working group create a learning and teaching framework prototype based on the findings. In the second phase, surveys were used to elicit community members' responses to the prototype, which was then refined.FindingsThe prototype was organized into three overarching categories, each containing several attributes. The attributes of the “Applied and Authentic” category were: interdisciplinary and transdisciplinary; experiential and participatory; flexible and individualized; outcomes based; and openly practiced. The attributes of the “Caring and Community-Based” category were: inclusive and diverse; community-based; supportive; team-based; co-creative; and place and virtual space-based. The attributes of the “Transformational” category were socially innovative; respectful of Indigenous peoples and traditions; impactful; and reflective.Originality/valueThis article should interest higher education institutions seeking to engage faculty, staff, students and others in practice conversations to develop a learning, teaching and research strategy. This research demonstrated that fostering practice conversations among diverse community members can be a powerful process for creating a common and integrated vision of excellent learning, teaching and research practice.
Value co-creation activities in retail ecosystems: well-being consequences
Authors: Gardiazabal Pilar , Bianchi Constanza 
Published: May 2021

Purpose
This paper aims to analyze the well-being consequences of value co-creation activities at an ecosystem level, focusing specifically on the micro and meso levels. This study is performed in a retail ecosystem, a highly relevant context where individuals spend a considerable amount of time and resources, but where well-being is usually not deemed as a relevant outcome.

Design/methodology/approach
The investigation analyzes qualitative data from micro and meso level actors of a retail ecosystem. At the micro-level, in-depth interviews performed with customers, employees and suppliers were assessed. The meso level analysis included most of the actors embedded in the retail ecosystem: employees’ headquarters, suppliers’ headquarters, nearby competitors, family, other retail outlets and external employees.

Findings
This study is one of the first in the transformative service research area to analyze well-being from a retail ecosystem perspective. Hence, this analysis broadens the literature on transformative service by considering supermarket retailing, an everyday service context that is not assumed to generate well-being outcomes. Results reveal that actors who spend more time or have fewer options available for them in the retail ecosystem see their well-being deeply affected. It also extends the conceptualization of value co-creation to a retail ecosystem, a specific ecosystem, which differs from previous studies that focus mostly on health-care ecosystems.

Research limitations/implications
Although useful to understand new insights, a limitation of this investigation is that it is based upon a single qualitative study.

Practical implications
The study portrays how activities happening within a business context have consequences beyond traditional measures such as loyalty or turn-over. It proposes specific value co-creation actions to be performed by employees, suppliers and customers to promote positive well-being consequences for the micro and meso level retail ecosystem.

Social implications
Retail ecosystems are usually not deemed as relevant when trying to understand societal well-being outcomes. This study empirically depicts that all services, even the ones without transformative goals, need to be aware of the impact they have on societal well-being.

Originality/value
This paper provides a novel conceptualization of well-being effects in a retail ecosystem. Specifically, this is the first study in the transformative service research literature to identify the micro and meso level well-being consequences of value co-creation activities within a retail ecosystem.
Does GHRM spur business performance via green corporate citizenship, green corporate reputation and environmental performance?
Authors: Opoku Mensah Abigail , Afum Ebenezer , Sam Evelyn Ama 
Published: May 2021

PurposeThis study investigates the effect of green human resource management (GHRM) on green corporate citizenship (GCC), green corporate reputation (GCR), environmental performance (EP) and business performance (BP). The study further examines the mediation roles of GCC, GCR and EP between the direct paths.Design/methodology/approachData for the study is solicited from 185 managers from Ghanaian oil and gas companies. Partial least squares-structural equation modeling (PLS-SEM) is applied to test all hypotheses.FindingsThe results suggest that GHRM has a significant positive effect on GCC, green reputation, environmental and BPs. The mediation analysis further shows that, unlike EP which plays no mediation role, GCC and green reputation play complementary partial mediation role between GHRM and BP. Moreover, GCC mediates the relationship between GHRM and EP.Originality/valueAside from magnifying environmental management and the GHRM literature, this study is among the few that investigates the connection role between GHRM, GCC, green reputation, environmental and BPs, especially from direct effects and mediation analysis standpoint.
Comparative analysis of anti-reflection coatings on solar PV cells through TiO2and SiO2nanoparticles
Authors: Sivakumar Rajkamal , Gopalakrishnan Prabhakaran , Abdul Razak Mohamed Sikkander 
Published: May 2021

PurposePhoton absorbance and reflectance are the most important parameters for the recombination of electron-hole pairs. Bandgap energy plays a vital role in photon absorption. That is, the photons with energy greater than band gap energy are absorbed. Also, the refractive index of semiconductors is responsible for photon reflection, as the surface with the highest refractive index will reflect more photons than a surface with have a low refractive index. The purpose of this paper is to improvise the absorbance and reduce the reflectance of photons on the front surface of solar cells.Design/methodology/approachPhoton reflection is results in reduction in electron-hole pair generation due to the high refractive index of semiconductive materials. To overcome this problem, an Anti-reflection (AR) coating of TiO2and SiO2is undertaken on solar cells through the Sol-spin coating method. Finally, the effectiveness of the Anti-Reflection coating is scrutinized through UV Vis-Spectroscopy, which provides details regarding reflectance, absorbance and bandgap energy characteristics.FindingsUV–visible spectroscopy was used to measure the responses from the samples. The samples responded to the ultraviolet and visible range of electromagnetic radiation perfectly. UV spectroscopy was done before and after the antireflection coating of TiO2and SiO2over the solar cell to find their corresponding extreme reflectance and absorbance values. The effects of TiO2and SiO2were evaluated from the results.Originality/valueIn this research work, the authors have done anti-reflection coating over solar cells with nanoparticles derived from sol-gel process. Absorbance of photons observed through diffuse reflection method.
Proteomic profiling and glycomic analysis of the yeast cell wall in strains with Aflatoxin B1 elimination ability
Authors: García‐Béjar Beatriz , Owens Rebecca A. , Briones Ana , Arévalo‐Villena María 
Published: May 2021

SummaryThe use of microorganisms for Aflatoxin B1 elimination has been studied as a new alternative tool and it is known that cell wall carried out a critical role. For that reason, cell wall and soluble intracellular fraction of eight yeasts with AFB1 detoxification capability were analysed. The quantitative and qualitative comparative label‐free proteomic allowed the identification of diverse common constituent proteins, which revealed that putative cell wall proteins entailed less than 10% of the total proteome. It was possible to characterize different enzymes linked to cell wall polysaccharides biosynthesis as well as other proteins related with the cell wall organization and regulation. Additionally, the concentration of the principal polysaccharides was determined which permitted us to observe that β‐glucans concentration was higher than mannans in most of the samples. In order to better understand the biosorption role of the cell wall against the AFB1, an antimycotic (Caspofungin) was used to damage the cell wall structure. This assay allowed the observation of an effect on the normal growth of those yeasts with damaged cell walls that were exposed to AFB1. This effect was not observed in yeast with intact cell walls, which may reveal a protective role of this structure against mycotoxins.

AbstractObjectiveTo estimate health care systems' value in treating major illnesses for each US state and identify system characteristics associated with value.Data sourcesAnnual condition‐specific death and incidence estimates for each US state from the Global Burden Disease 2019 Study and annual health care spending per person for each state from the National Health Expenditure Accounts.Study designUsing non‐linear meta‐stochastic frontier analysis, mortality incidence ratios for 136 major treatable illnesses were regressed separately on per capita health care spending and key covariates such as age, obesity, smoking, and educational attainment. State‐ and year‐specific inefficiency estimates were extracted for each health condition and combined to create a single estimate of health care delivery system value for each US state for each year, 1991–2014. The association between changes in health care value and changes in 23 key health care system characteristics and state policies was measured.Data collection/extraction methodsNot applicable.Principal findingsUS state with relatively high spending per person or relatively poor health‐outcomes were shown to have low health care delivery system value. New Jersey, Maryland, Florida, Arizona, and New York attained the highest value scores in 2014 (81 [95% uncertainty interval 72‐88], 80 [72‐87], 80 [71‐86], 77 [69‐84], and 77 [66‐85], respectively), after controlling for health care spending, age, obesity, smoking, physical activity, race, and educational attainment. Greater market concentration of hospitals and of insurers were associated with worse health care value (p‐value ranging from <0.01 to 0.02). Higher hospital geographic density and use were also associated with worse health care value (p‐value ranging from 0.03 to 0.05). Enrollment in Medicare Advantage HMOs was associated with better value, as was more generous Medicaid income eligibility (p‐value 0.04 and 0.01).ConclusionsSubstantial variation in the value of health care exists across states. Key health system characteristics such as market concentration and provider density were associated with value.
