Career constructions and a feminist standpoint on the meaning of context
Authors: Karam Charlotte M. , Afiouni Fida 
Published: December 2020

AbstractThis paper explores how context shapes the career constructions of 40 Lebanese female professionals. Starting with career construction theory (CCT), we leverage feminist standpoint theory (FST) to propose a hybrid analytic framework. With this framework, we invite CCT researchers to theorize career constructions as situated. The situatedness of career constructions calls for the exploration of an individual's career choices, coupled with the simultaneous potential constraints on choice emanating from collective experiences of historical and sociopolitical oppression. Theorizing contextual complexities in this way leads to a more nuanced tracing of how the personal experiences of challenge, and for some, the oppressive aspects of collective histories are selectively used to construct a cohesive sense of career storied self, each with distinctive implications for the domains of CCT—Vocational Personality (the what), Career Adaptability (the how), and Life Theme (the why). Our analysis reveals three key patterns: (1) advancing the professional field (vocational expert), (2) seeking self‐vindication (adaptive rebel), and (3) engaging in activism (sympathetic activist vs. epistemically privileged activist). We conclude by discussing the value of our framework, thereby highlighting how acknowledging situatedness helps to inform our understandings of career patterns and of the “politicization” of career trajectories.
Gender, business and human rights: Academic activism as critical engagement in neoliberal times
Authors: Grosser Kate 
Published: December 2020

AbstractThis paper contributes to the debate about academic activism in organization studies through an exploration of my engagement with recent international policy‐making relating to gender, business, and human rights. It brings social movement theory to the debate to elucidate how our work as academic activists can be conceived of in terms of social movement strategies with respect to political opportunities, mobilizing structures, and strategic framing processes. The aim is to further elucidate what we do as academic activists, and how such actions might advance feminist social movement agendas through a process that is both critical AND engaged in neoliberal contexts. I conclude with a discussion of the implications for Gender, Work & Organization (GWO) scholars and the GWO journal.

Authors: Singh Agyapal , Maini Jiwan Jyoti 
Published: December 2020

AbstractThe study examines the relationship between Quality of work life (QWL) and job performance among the faculty of technical institutions in the state of Punjab, India. Data collected from a sample of 445 respondents through a structured questionnaire have been put to data analysis with the help of the Statistical Package for the Social Sciences (SPSS 20). Four factors that are associated with QWL (i.e., management policies, fair pay, work environment, and job design & social space) have been identified through Exploratory Factor Analysis (EFA). Subsequently, the relationship between the identified factors of QWL and job performance is modelled through Partial Least Squares Structural Equation Modelling (PLS‐SEM). The results infer that all four factors of QWL have a substantial association with job performance of the faculty. The study puts forward improvement in the level of existing institutional measures to ensure a superior QWL and improved performance of faculty in the technical education sector.

Published: December 2020

AbstractRefractory materials such as mullite, andalusite, forsterite, and cordierite are generally used to prepare saggers for the calcination of Li‐ion battery Li(NixCoyMnz)O2 (LNCM) cathode material. However, these compounds are prone to be attacked by the LNCM materials, thereby leading to short life spans and contamination of the Li‐ion battery cathode materials. To improve the corrosion resistance of refractory sagger materials, the most clear cut‐way is enhancing the corrosion resistance of matrix using a new refractory component. Potassium aluminate (K2O·11Al2O3, KA11) with an excellent corrosion resistance against alkaline oxide was synthesized via solid‐state method using potassium carbonate (K2CO3) and industrial alumina powder (Al2O3). Interactions between KA11 and LNCM cathode materials at 800°C–1100°C were characterized by refractory‐LNCM precursor laboratory‐scale tests to understand the corrosion behavior of KA11. The microstructure and phase composition of synthesized KA11 and the calcined KA11‐LNCM mixture cylinders were analyzed with SEM and XRD. The observations reveal that KA11 shows a better corrosion resistance to LNCM materials compared with mullite, cordierite, and forsterite. The addition of synthesized KA11 also favors the thermal shock resistances of mullite‐based sagger materials.

Published: December 2020

AbstractIntroductionAnaemia, a condition characterized by reduced oxygen‐carrying capacity, is a widespread public health problem with major consequences for human health as well as social and economic development. Prompt and accurate diagnosis as well as effective management of iron deficiency anaemia (IDA) is important to prevent the undesired adverse clinical outcomes.MethodsThe purpose of the study was to assess the adequacy of IDA diagnosis and management within the Namibian private healthcare system. In this study, we used a quantitative, descriptive research design and data collection methods. The design was also nonexperimental in nature, employing a survey instrument to collect data. In total, 51 questionnaires were administered to private medical practitioners.ResultsThe surveyed medical practitioners used different Standard Treatment Guidelines (STGs) in managing IDA cases, with the majority (76.5%) using the Namibia STGs. The other guidelines and their usage rates were as follows: World Health Organization guidelines (39.2%), Standard Treatment Guidelines and Essential Medicine List for South Africa (19.6%) and Essential Medicine List and Standard Treatment Guidelines for Zimbabwe (19.6%). Most of the medical practitioners used Namibian STGs although others used other treatment guidelines at their discretion.ConclusionThe study concluded that medical practitioners follow different guidelines and reference documents when dealing with patients with suspected IDA. Adherence to a single reference document would enable standardization of clinical practice. Management of IDA in the Namibian private healthcare system could be improved. To ensure adequate IDA management and prompt resolution of iron deficiency anaemia, we recommended the need to review the Namibia Standard Treatment guidelines and to ensure that training on the guidelines is offered.

Published: December 2020

AbstractBackgroundArthritis is a common condition, which frequently involves the hands. Patients with inflammatory arthritis have been shown to experience significant delays in diagnosis.AimTo develop and test a screening tool combining an image of a patient's hands, a short series of questions and a single examination technique to determine the most likely diagnosis in a patient presenting with hand arthritis. Machine learning techniques were used to develop separate algorithms for each component, which were combined to produce a diagnosis.MethodsA total of 280 consecutive new patients presenting to a rheumatology practice with hand arthritis were enrolled. Each patient completed a nine‐part questionnaire, had photographs taken of each hand and had a single examination result recorded. The rheumatologist diagnosis was recorded following a 45‐min consultation. The photograph algorithm was developed from 1000 previous hand images and machine learning techniques were applied to the questionnaire results, training several models against the diagnosis from the rheumatologist.ResultsThe combined algorithms in the present study were able to predict inflammatory arthritis with an accuracy, precision, recall and specificity of 96.8%, 97.2%, 98.6% and 90.5% respectively. Similar results were found when inflammatory arthritis was subclassified into rheumatoid arthritis and psoriatic arthritis. The corresponding figures for osteoarthritis were 79.6%, 85.9%, 61.9% and 92.6%.ConclusionThe present study demonstrates a novel application combining image processing and a patient questionnaire with applied machine‐learning methods to facilitate the diagnosis of patients presenting with hand arthritis. Preliminary results are encouraging for the application of such techniques in clinical practice.

AbstractThe optical‐magnetic multifunctional materials are of great importance owing to their potential applications in intersect discipline fields. However, the multifunctional materials with satisfied optical and magnetic property are limited, and the modulation mechanism of their magneto‐optical property related to their structure feature is ambiguous. Here, a new multifunctional solid solution phosphors Ca18K3Sc1‐xSmx(PO4)14 (0 ≤ x ≤ 1) are designed based on composition engineering and are successfully synthesized. The detailed structure feature including the structural evolution of the crystallographic parameters and local lattice environment as well as polyhedral distortion behavior are investigated through X‐ray diffraction Rietveld structure refinement for Ca18K3Sc1‐xSmx(PO4)14 in the full range (0 ≤ x ≤ 1). The photoluminescence spectra indicate that Ca18K3Sc1‐xSmx(PO4)14 (0 ≤ x ≤ 1) can emit intense orange‐red emission (IQE~42.6%) under ultraviolet light excitation ascribed to the4G5/2 ‐6H7/2 transition of Sm3+ ions. The structure modulated luminescence behavior, for example, the tunable emission ratio of I648/I565, high quenching content, and electric multipole interaction mechanism are studied. The versatile phosphors can exhibit tunable orange‐red cathodoluminescence emission along with increasing the accelerating voltage. The electron transition mechanism of the photoluminescence and cathodoluminescence behavior is further discussed through a simple schematic diagram. Moreover, Ca18K3Sc1‐xSmx(PO4)14 (0 ≤ x ≤ 1) shows a ferromagnetic behavior with controllable magnetization and coercive field. Finally, the impact of Fe ions on the photoluminescence and magnetic property of Ca18K3Sc1‐yFey(PO4)14: 0.4Sm3+ (0 ≤ y ≤ 0.05 and y = 1) phosphors are investigated. The current research can provide some ideas and mechanism to design and investigate more novel magneto‐optical muntifunctional materials for versatile applications in intersect disciplines.

Published: December 2020

AbstractA series of zirconolite ceramics with composition CaZr1‐xThxTi2O7 (Δx = 0.10) were reactively sintered at 1350°C for 20 h, in air (0 ≤ x ≤ 0.60) and 5% H2/N2 (0 ≤ x ≤ 0.40). A sample with composition corresponding to x = 0.20 was also produced by hot isostatic pressing (HIP) at 1300°C and 100 MPa for 4 hours. Th4+ immobilization was most readily achieved under oxidizing conditions, with Th4+ preferentially incorporated within a pyrochlore‐structured phase in the range 0.10 ≤ x ≤ 0.50, yet formation of the zirconolite‐4M polytype was not observed. We report the novel synthesis of single‐phase pyrochlore with nominal composition CaZr0.40Th0.60Ti2O7 when targeting x = 0.60. Th4+ incorporation under reducing conditions produced a secondary Th‐bearing perovskite, comprising 24.2 ± 0.6 wt% of the phase assemblage when targeting x = 0.40, alongside 8.8 ± 0.3 wt% undigested ThO2. Under reducing conditions, powder XRD data were consistent with zirconolite adopting the 3T polytype structure. The sample produced by HIP presented a nonequilibrium phase assemblage, yielding a major phase of zirconolite‐2M alongside accessory Th4+‐bearing phases ThTi2O6, ThO2, and perovskite. These data highlight the efficacy of Th4+ as a Pu4+ surrogate, with implications for the formation of Zr‐stabilized Th‐pyrochlore phases as matrices for waste with elevated Th4+ content.

Published: December 2020

AbstractAimThis study aimed to explore the role and impact of advanced practice nurses (APNs) in care of patients following fragility hip fracture by systematically reviewing the available evidence.Review DesignSystematic review.Data sourcesA search of the databases Ovid Medline, CINAHL, Embase, Emcare, Cochrane Library, and Google Scholar was conducted from January–February 2019.MethodThis systematic review adhered to The PRISMA Statement. Study selection was managed using the Covidence software platform and quality was assessed using JBI Critical appraisal tools. Studies included adults >18 years and described the role and impact of APNs in care of patients following fragility hip fracture on clinical and non‐clinical outcomes.ResultsThere were 19 papers identified that met the inclusion/exclusion criteria. Quality was graded as moderate to low risk of bias. Six characteristics of APNs were identified: (1) coordination; (2) collaboration; (3) education; (4) assessment, investigation and treatment recommendations; (5) discharge planning, support and follow up; and (6) documentation. Overall mortality and LOS improved when characteristics of the APN role were present.ConclusionKey findings from this systematic review showed: (1) The APN title and role are not clearly defined, but characteristics of the APN role are evident; (2) characteristics of APNs promote the delivery of best practice hip fracture care and have a positive impact on mortality and LOS; and (3) innovative service delivery models involving APNs should be considered to address future projections of hip fracture rates and improve outcomes.ImpactThis systematic review provides evidence of the role characteristics of APNs in fragility hip fracture and the impact of the role on outcomes. Findings from this research could be used to develop service delivery models using APNs to care for patients following fragility hip fracture and to inform practice where APN roles may improve outcomes for other patient cohorts.
Influence of past and current factors on the beta diversity of coastal lagoon fish communities in South America
Authors: Guimarães Taís de Fátima Ramos , Petry Ana Cristina , Hartz Sandra Maria , Becker Fernando Gertum 
Published: December 2020

AbstractAimFish community composition is shaped by current and historical factors. In recently formed ecosystems, however, as the Quaternary coastal lagoons of South America, the influence of historical factors has less frequently been investigated. The low rate of endemism in these lagoons suggests a limited role for speciation while their dynamic formation history suggests local extinction and dispersal limitation could have affected present species composition. We aimed to assess the influence of past and current factors on the beta diversity of those communities and explore the main processes involved.LocationAtlantic coast of South America.TaxonFishes (173 species).MethodsWe built a dataset of species occurrence in 129 lagoons across eight freshwater ecoregions of the world (FEOWs) located between latitudes 0° and 36°, and calculated beta diversity (βjac) and its turnover (βjtu) and nestedness (βjne) components. We used a partial Mantel test and multiple regressions on distance matrices to evaluate the importance of past and current factors, and of geographical distance in determining beta diversity. Past variables were those representing the historical freshwater habitat during the last glacial maximum (LGM), and contemporary variables were those related to current habitat.ResultsWe found high values of βjac within the FEOWs, with βjtu prevailing over βjne. Both past (palaeodrainage) and current (drainage area, salinity and lagoon area) factors affected species dissimilarity (βjac = 46%) and its components (βjtu = 44% and βjne = 20%), although explanation was, in part, shared with geographical distance. Individually, the influence of past factors was prevalent in beta diversity and its components.Main conclusionsThe large influence of the past factors on beta diversity suggests that major changes in the availability of freshwater habitats and connectivity since the Pleistocene must have affected the colonization, extinction and recolonization processes of fishes along the eastern coast of South America. We suggest that the high beta diversity values result from limited dispersal after extinctions in the LGM. The dissimilar freshwater fish communities currently seen result from heterogeneous subsets of the regional species pool that persisted in landscape refuges during past sea level increases and then recolonized coastal lagoons.

AbstractAimPhylogeographic studies show how historical and current changes in landscapes shape the geographic distribution of genetic diversity in species of animals and plants. In particular, for the species of the Diagonal of Open Formations (DOF), the compartmentalization of the Central Brazilian Plateau (CBP) during the Tertiary and climatic oscillations during the Quaternary have often been invoked to explain the origin and current patterns of biodiversity. We investigated how landscape changes and climatic oscillations shaped the distribution and diversification history of a widespread South American treefrog.LocationSouth American Diagonal of Open Formations (DOF) including Caatinga, Cerrado, and Chaco biomes.TaxonTreefrog Boana raniceps.MethodsWe used a multi‐locus dataset from 288 individual frogs collected at 115 localities throughout most of the species’ distribution. We used population assignment analysis, species distribution models, historical demography models, approximate Bayesian computation and landscape genetic analyses to test alternative hypotheses of diversification.ResultsWe found two genetic lineages that diverged during the mid‐Pleistocene with continued gene flow. Approximate Bayesian computation supported a scenario of isolation with migration until the Last Glacial Maximum, followed by more recent population expansion in north‐eastern Brazil and stability at the southwest in South America. Isolation by environment was the best predictor of genetic distance between populations, which is in accordance with their different environmental niches. As Boana raniceps is a lowland species, steep slopes in the CBP likely restrained gene flow enough to sustain population divergence. We found evidence for major range contraction during the Last Glacial Maximum, raising the possibility of synergic action of climate change and the CBP compartmentalization in regulating migration.Main conclusionsOur findings highlight how landscape and climatic changes can shape the diversification of DOF biota. Past climatic fluctuations and environmental resistance due to topography acted in concert, forming a semipermeable barrier to gene flow, promoting intraspecific differentiation in a continentally distributed species.

AbstractAs one of the most aggressive malignancies, non‐small cell lung carcinoma (NSCLC) has high risks of death. It has been demonstrated that circRNAs accelerate NSCLC progression, but the underlying molecular mechanisms of circRNAs in NSCLC were still obscure. In the first place, the circRNA microarray of NSCLC was investigated in this study, and hsa_circ_0008003 (circ‐0008003) was chosen as the research object. Then, it was unveiled that the expression of circ‐0008003 examined via qRT‐PCR was elevated in tumour tissues relative to the non‐tumour tissues, which was associated with TNM stage and lymphatic metastasis in NSCLC. Additionally, the prognosis of NSCLC patients with high circ‐0008003 level was poor. Besides, circ‐0008003 silencing dampened the invasion and proliferation of NSCLC cells. Next, according to the mechanistic studies, circ‐0008003 functioned as a ceRNA of ZNF281 in NSCLC by acting as the endogenous sponge for miR‐488, which was proved to be a tumour suppressor in NSCLC. Additionally, ZNF281 overexpression and miR‐488 suppression recovered the influences of repressed circ‐0008003 on NSCLC cellular processes. It was validated in this research that circ‐0008003 triggered tumour formation in NSCLC, which was adjusted via miR‐488/ZNF281 axis, casting a novel light on the resultful target for treating NSCLC and predicting the prognosis.

Published: December 2020

AbstractHepatic fibrosis (HF) is involved in aggravated wound‐healing response as chronic liver injury. Extracellular vesicles (EVs) carrying microRNA (miR) have been reported as therapeutic targets for liver diseases. In this study, we set out to explore whether adipose‐derived mesenchymal stem cells (ADMSCs)‐derived EVs containing miR‐150‐5p affect the progression of HF. Carbon tetrachloride (CCl4) was firstly used to induce HF mouse models in C57BL/6J mice, and activation of hepatic stellate cells (HSCs) was achieved using transforming growth factor β (TGF‐β). EVs were then isolated from ADMSCs and co‐cultured with HSCs. The relationship between miR‐150‐5p and CXCL1 was identified using dual luciferase gene reporter assay. Following loss‐ and gain‐function experimentation, HSC proliferation was examined by MTT assay, and levels of fibrosis‐, HSC activation‐ and apoptosis‐related genes were determined in vitro. Additionally, pathological scores, collagen volume fraction (CVF) as well as levels of inflammation‐ and hepatic injury‐associated genes were determined in in vivo. Down‐regulated miR‐150‐5p and elevated CXCL1 expression levels were detected in HF tissues. ADMSCs‐derived EVs transferred miR‐150‐5p to HSCs. CXCL1 was further verified as the downstream target gene of miR‐150‐5p. Moreover, ADMSCs‐EVs containing miR‐150‐5p markedly inhibited HSC proliferation and activation in vitro. Meanwhile, in vivo experiments also concurred with the aforementioned results as demonstrated by inhibited CVF, reduced inflammatory factor levels and hepatic injury‐associated indicators. Both experiments results were could be reversed by CXCL1 over‐expression. Collectively, our findings indicate that ADMSCs‐derived EVs containing miR‐150‐5p attenuate HF by inhibiting the CXCL1 expression.
