Caring for students in postsecondary open educational resource (OER) and open education initiatives: inviting student participation and voice
Authors: McLure Merinda , Sinkinson Caroline 
Published: August 2020

PurposeThis paper aims to examine librarians’ professional motivations and theoretical perspectives to attend to care and student voice, as they pursue open educational resource (OER) initiatives in higher education.Design/methodology/approachThe authors examine OER initiatives that serve as models for their work at the University of Colorado Boulder (CU Boulder), describe how they have attended to care and student voice in their work to date and reflect on how they hope to continue to do so in their future OER initiatives.FindingsThe authors find connections between theoretical perspectives for care in education and the values and ethics of both the open education movement and librarianship. They propose that these connections provide a foundation for librarians to align their professional motivations and practices in support of learning. The authors provide examples of OER programming that attend to care and student voice and offer related strategies for practitioners to consider.Originality/valueLibrarians at many post-secondary institutions provide critical advocacy and support the adoption, adaptation and creation of OER in higher education. Theories of care, values and ethics in the open education movement and librarianship provide a foundation for librarians to attend to care and elevate student voice as they undertake OER advocacy and initiatives.
The effect of TQM practices on operational performance: an empirical analysis of ISO 9001: 2008 certified manufacturing organizations in Ethiopia
Authors: Kebede Adem Mulugeta , Virdi Sandeep Singh 
Published: August 2020

PurposeThis study is aimed at examining the effect of Total Quality Management (TQM) practices on the operational performance of ISO 9001:2008 certified manufacturing companies in Ethiopia.Design/methodology/approachA cross-sectional survey was conducted to meet the purpose. Primary data was collected from the managers and senior experts working under the production and quality management units of the surveyed firms. Data was obtained from a survey of 302 participants found in 73 ISO 9001:2008 certified manufacturing organizations. Both EFA and CFA were applied to validate and confirm the instrument, and Structural Equation Modeling (SEM) was used to test the hypotheses.FindingsThe results revealed that among the practices of TQM used in the model only supplier quality management, continuous improvement and process management were found to have significant and positive effect on the operational performance of the ISO 9001:2008 certified manufacturing organizations in Ethiopia.Research limitations/implicationsFuture studies are suggested to consider some contextual variables such as firm age, scope of operation, firm size and firm strategy while addressing the objective.Practical implicationsThe study will encourage managers of manufacturing companies in Ethiopia to utilize a reliable and valid framework of TQM practices for better operational performance results.Originality/valueThe fact that Ethiopian manufacturing organizations are required to improve their product's quality in order to improve their productivity and enhance their competitiveness in a global market is the rationale of this study. Even though several studies have evolved to scrutinize the link between TQM and operational performance across the world, nearly nothing, is known about this linkage in Ethiopia. Thus, the study represents one of the first attempts to empirically investigate this linkage in Ethiopian context.

Published: August 2020

With the efficacy of couple therapy no longer in doubt, researchers are seeking to identify client characteristics that explain variability in retention and outcomes. We examined the link between two self‐reported characteristics, attachment insecurity and treatment expectations (for self, partner, and outcome), in a Mechanical Turk sample of 182 adults in committed relationships. A significant canonical correlation accounted for 27 per cent of the variance between the two sets of variables. Interpretation of the structure coefficients indicated that (1) low role expectations for one’s partner were predicted by high attachment anxiety; (2) low expectations for the outcome of couple therapy were predicted by high attachment avoidance coupled with low attachment anxiety; and (3) high self and outcome expectations were predicted by high attachment anxiety when attachment avoidance was low. We discuss the implications of these results for engaging couples with insecure attachment patterns.Practitioner points

Expectations for couple therapy are measurable, and related to levels of attachment insecurity

Results of this study underscore the importance of clinicians inquiring early on in treatment about what each partner anticipates about the process of couple therapy

Clinicians should work gently and creatively with clients with low expectations to help them safely engage in the treatment process

Recognising attachment insecurity should be a signal to clinicians to monitor relevant attachment behaviours and related expectations

ObjectiveTo compare neonatal outcomes of women with a body mass index (BMI) of ≥35 kg/m2 who underwent a trial of labour with those of women who underwent a planned primary caesarean section (CS).DesignA retrospective cohort study of births between April 2012 and March 2014.SettingA provincial database: Better Outcomes Registry & Network (BORN) Ontario, Canada.PopulationA cohort of 8752 women with a BMI of ≥35 kg/m2 who had a singleton birth at 38–42 weeks of gestation.MethodsNeonatal outcomes were compared between women who underwent a trial of labour (with either a successful vaginal birth or intrapartum CS) and those who underwent a planned CS.Main outcome measureA composite of any of the following outcomes: intrapartum neonatal death, neonatal intensive care unit admission, 5‐minute Apgar score of <7 or umbilical artery pH of <7.1.ResultsDuring the study period, 8433 (96.4%) women had a trial of labour and 319 (3.6%) had a planned CS. Intrapartum CS was performed in 1644 (19.5%) cases. There was no association between planned mode of delivery and the primary outcome (aOR 0.80, 95% CI 0.59–1.07). The primary outcome was lower among women who had a successful trial of labour (aOR 0.67, 95% CI 0.50–0.91) and was higher among women who had a failed trial of labour (aOR 1.74, 95% CI 1.21–2.48), compared with women who underwent a planned CS.ConclusionsIn women with a BMI of ≥35 kg/m2 at a gestational age of 38–42 weeks, neonatal outcomes are comparable between planned vaginal delivery and planned CS, although a failed trial of labour is at risk of adverse neonatal outcome.Tweetable abstractNeonatal outcomes are not affected by planned mode of delivery in women who are obese, with a BMI of ≥35 kg/m2.
Civilian Forensic Technician and Sworn Police Officer Job‐Related Stress
Authors: McKay‐Davis Selena , Robinson Tharinia , Sebetan Ismail M. , Stein Paul 
Published: August 2020

AbstractForensic Technicians provide crime scene investigation services and are exposed to stressful violent crimes, motor vehicle accidents, biological or chemical hazards, and other appalling imagery. Forensic Technicians would likely experience physical and psychological stress after exposure to trauma, and security vulnerabilities similar to Sworn Police Officers. The perceived availability of mental health resources, job‐related physical, psychological stress, and traumatic experiences of both Forensic Technicians and Sworn Police Officers from California law enforcement agencies were investigated using a self‐reported survey. Responses were evaluated for any significant differences in the perceived stress, job‐related physical stress, and resulting psychological impact affecting the participants. The survey contained a mix of True/False, Circle/Check the Appropriate Box, or Likert Scale (1–5) responses. The results were evaluated statistically and discussed. Results indicated Sworn Police Officers and Forensic Technicians have different on‐duty stress levels, but similar off‐duty stress levels. Nearly two‐thirds of 54 job‐related stressors were not significantly different between the two occupations. However, Forensic Technicians reported more adverse effects in 17 physical and psychological job‐related activities compared with Sworn Police Officers. Forensic Technicians reported lower awareness levels and availability of agency mental health support services than were reported by Sworn Police Officers. This study reports for the first time an unexpected outcome that perceived and job‐related psychological stress is greater for Forensic Technicians than Sworn Police Officers. Possible reasons for this disparity will be discussed as well as stress management tools that should be implemented to reduce health risk factors for both career professionals as well as increase public safety.
Family‐supportive organisational culture, work–family balance satisfaction and government effectiveness: Evidence from four countries

Published: August 2020

AbstractThis study examines the extent to which perceptions of family‐friendly organisational culture relate to employees' satisfaction with work–family balance (SATWFB) and how this, in turn, associates with their turnover intentions (TIs). Furthermore, we explore the extent to which employee experiences of different levels of government effectiveness (GE; high, medium and low) moderate these associations. Drawing on the work–home resources (W‐HR) model, we test our hypotheses with a sample of 1185 employees drawn from countries with substantially different levels of GE—Nigeria, the Philippines, Guatemala and Spain. Our results show that employees' perceptions of SATWFB mediate the relationship between the two dimensions of family‐friendly organisational culture and TIs of employees. This mediation is weaker for countries where employees experience high GE. Our findings contribute to research on the drivers of work–family balance satisfaction from a cultural and organisational perspective. We expand this line of research by introducing a new resource: GE. Our focus on four different national contexts also strengthens the comparative work–family balance literature.
Preparation and characterization of oleogel emulsions: A comparative study between the use of recovered and commercial sunflower waxes as structuring agent

Published: August 2020

AbstractThe objective of this study was to evaluate the capacity of recovered sunflower waxes (RW) to be used as a structuring agent of oleogel emulsions in comparison with commercial sunflower waxes (CW). RW were recovered from filter cake with a simple hexane extraction procedure. For this purpose, oleogel‐based emulsions were prepared using 2%, 3.5%, and 5% w/w wax in oleogel and characterized using several physicochemical techniques in order to evaluate the potential of these materials to develop products with functionality similar to commercial margarines. The total wax esters content of RW was similar to that of the CW and was mainly composed of wax esters with more than 44 carbon atoms (crystallizable waxes). Polarized light and scanning electron microscopy showed that RW produced emulsions with more intricate crystalline networks composed of smaller platelets than CW. The melting enthalpy was greater in CW emulsions than RW emulsions, which was in agreement with the thermal behavior found for CW and RW. The oil binding capacity of CW oleogel emulsions was higher than the RW ones, and this property improved with the increase in wax concentration. Likewise, the elastic behavior, as well as hardness and adhesiveness, increased with the wax content as a result of a greater amount of microstructural elements composing the network of these semisolid materials. The oleogel emulsions stability was monitored for 2 months at room temperature. The increase of CW concentration slowed down the coalescence process, but this behavior was not observed for RW emulsions. Obtained results demonstrated that RW oleogel emulsions have the potential to replace the functionality of soft spreadable products.Practical ApplicationWax esters are organogelators that have been shown to successfully gel liquid oil at low concentrations. In this work, we are interested in evaluating the potential of sunflower waxes recovered from filter cake, a waste generated during refined oil production, to structure oil and produce oil‐in‐water emulsions with functionality similar to commercial margarines. With this, it is sought not only the development of healthier fats but also the use of wastes to generate more sustainable products.
New approaches to species delimitation and population structure of anthozoans: Two case studies of octocorals using ultraconserved elements and exons

AbstractAs coral populations decline worldwide in the face of ongoing environmental change, documenting their distribution, diversity and conservation status is now more imperative than ever. Accurate delimitation and identification of species is a critical first step. This task, however, is not trivial as morphological variation and slowly evolving molecular markers confound species identification. New approaches to species delimitation in corals are needed to overcome these challenges. Here, we test whether target enrichment of ultraconserved elements (UCEs) and exons can be used for delimiting species boundaries and population structure within species of corals by focusing on two octocoral genera, Alcyonium and Sinularia, as exemplary case studies. We designed an updated bait set (29,181 baits) to target‐capture 3,023 UCE and exon loci, recovering a mean of 1,910 ± 168 SD per sample with a mean length of 1,055 ± 208 bp. Similar numbers of loci were recovered from Sinularia (1,946 ± 227 SD) and Alcyonium (1,863 ± 177 SD). Species‐level phylogenies were highly supported for both genera. Clustering methods based on filtered single nucleotide polymorphisms delimited species and populations that are congruent with previous allozyme, DNA barcoding, reproductive and ecological data for Alcyonium, and offered further evidence of hybridization among species. For Sinularia, results were congruent with those obtained from a previous study using restriction site associated DNA sequencing. Both case studies demonstrate the utility of target‐enrichment of UCEs and exons to address a wide range of evolutionary and taxonomic questions across deep to shallow timescales in corals.
The Synergistic and Neuroprotective Effects of Alcohol–Antioxidant Treatment on Blood–Brain Barrier Endothelial Cells
Authors: Fisher David , Thomas Kelly Angelique , Abdul‐Rasool Sahar 
Published: August 2020

BackgroundAlcohol (EtOH) is reported to adversely affect one of the most crucial roles of the blood–brain barrier (BBB), the regulation of its permeability, thereby compromising the stability of the homeostatic environment of the brain. The central component of the BBB, endothelial cells (ECs), regulates BBB transcellular transport, while their paracellular pathways are made virtually impermeable by molecular structures called tight junctions (TJs). These TJs are composed of proteins, such as claudin‐5, a protein involved in the regulation of paracellular permeability and of key interest in this study.Methods and ResultsThe working hypothesis of this study postulated that the high levels of antioxidants (AOs) in the fermented Aspalathus linearis (Rooibos; Rf) tincture may protect the ECs of the BBB against oxidative stress induced by EtOH exposure. Cells were exposed for 24 hours to selected concentrations of EtOH (25 and 100 mM), Rf (containing an antioxidant equivalence of 1.9 nM Aspalathin), and cotreatments of EtOH and Rf. Cell viability, live cell number, and toxicity were analyzed using the trypan blue exclusion assay. RT‐qPCR was implemented to quantify claudin‐5 transcription. In addition, permeability (Transepithelial Electrical Resistance) of bEnd5 monolayers was measured. The experimental timeline for the above‐mentioned parameters was 24 and 48 hours.ConclusionsOur study showed that simultaneous exposure of Rf and EtOH was able to negate the effects of EtOH on cell viability and cell proliferation, but was not able to reverse or reduce the effects of EtOH on claudin‐5 transcription and paracellular permeability. Furthermore, a novel finding in this study suggests that very low concentrations of AOs in tinctures such as Rooibos tea could profoundly alter the redox status of brain ECs.

ObjectiveObsessive‐compulsive disorder (OCD) is a complex psychiatric disorder with a substantial genetic contribution. While the specific variants underlying OCD's heritability are still unknown, findings from genome‐wide association studies (GWAS) corroborate the importance of common SNPs explaining the phenotypic variance in OCD. Investigating associations between the genetic liability for OCD, as reflected by a polygenic risk score (PRS), and potential endophenotypes of the disorder, such as the personality trait harm avoidance, may aid the understanding of functional pathways from genes to diagnostic phenotypes.MethodsWe derived PRS for OCD at several P‐value thresholds based on the latest Psychiatric Genomics Consortium OCD GWAS (2688 cases, 7037 controls) in an independent sample of OCD patients (n = 180), their unaffected first‐degree relatives (n = 108) and healthy controls (n = 200). Using linear regression, we tested whether these PRS are associated with the personality trait harm avoidance.ResultsResults showed that OCD PRS significantly predicted OCD status, with patients having the highest scores and relatives having intermediate scores. Furthermore, the genetic risk for OCD was associated with harm avoidance across the entire sample, and among OCD patients. As indicated by mediation analyses, harm avoidance mediated the association between the OCD PRS and OCD caseness. These results were observed at multiple P‐value thresholds and persisted after the exclusion of patients with a current comorbid major depressive or anxiety disorder.ConclusionOur findings support the polygenic nature of OCD and further validate harm avoidance as a candidate endophenotype and diathesis of OCD.

AbstractCommercially reared cavity‐nesting bees have been studied mainly in large, intensively managed orchards. However, knowledge on wild cavity‐nesting bee and wasp communities and their potential limitations in smaller orchards remain insufficient.
We compared the colonization rate of trapnests, nesting success, parasitism and response to flower resources of cavity‐nesting bees and wasps between apple orchards and nearby semi‐natural habitats (SNHs).
Trapnests were placed in orchards and neighbouring SNHs. Colonization dynamics were studied and herbaceous flower resources were estimated. Furthermore, nest and brood cell quantity, number of alive offspring and nest parasitism rate were assessed.
We found a higher colonization rate in the SNHs than in the orchards. Both bees and wasps made more nests, completed more brood cells and had a higher number of alive offspring in the SNHs. The number of bee nests in the orchards showed a positive correlation with the species richness of the flowering plants. The nest parasitism of wasps was higher in the SNHs.
Apple orchards in the studied small‐scale system were generally less colonized by cavity‐nesting hymenopterans than nearby SNHs that can be important reservoirs of these ecosystem service provider hymenopterans. Our results highlight the importance of diverse flowering herbaceous vegetation in the understory that increased the number of bee nests in orchards and that could have a positive effect on the nesting activity of the bee species active in summer. Therefore, management practices that support flowering plant species in the understory vegetation are highly recommended in such orchards.

AbstractBackgroundMale infertility is a major issue in human reproduction health, yet known genetic factors are only responsible for a small fraction of cases. TSGA10 is a testis‐specific protein that is highly conserved among different species. A previous study has reported a homozygous mutation in TSGA10 in a male infertile patient; however, function analysis of Tsga10 genes in knockout mice has not yet been undertaken.ObjectivesThe aim of the present work was to analyse the function of TSGA10 protein in the spermatogenesis of Tsga10+/− mice.Materials and methodsTsga10+/− mice were generated by CRISPR/Cas9 technology, in vitro fertilization (IVF), western blot, co‐immunoprecipitation and other methods were used to the function analysis.ResultsHeterozygous Tsga10 male mice created by CRISPR/Cas9 were infertile and presented significantly reduced sperm motility because of disordered mitochondrial sheath formation. Furthermore, TSGA10 can interact with GRP78 and NSUN2, which are associated with peri‐implantation lethality and the gonadotropin‐releasing hormone (GnRH) network.Discussion and conclusionWe demonstrate that deficiency of Tsga10 gene can lead to male infertility in mice. TSGA10 is involved in the correct arrangement of mitochondrial sheath in spermatozoa. Future studies on TSGA10 include an in‐depth exploration of the underlying mechanisms of TSGA10 in spermatogenesis, early embryonic development and GnRH network.
