Supplier-initiated ingredient/component branding
Authors: Aljafari Abdullah M. , Brown Tom J. 
Published: April 2020

Purpose
This paper aims to understand the process of initiating ingredient/component (IC) branding from the supplier's perspective. It proposes modeling entrepreneurial orientation (EO) as an antecedent factor and differentiation abilities (functional and reputational) as mediators. Investigating IC branding from the supplier's perspective is critical given the cost and risk associated with implementing such a strategy.

Design/methodology/approach
A total of 5,254 manufacturing companies were screened to identify IC supplier firms that meet certain criteria. Survey data were collected from 77 top managers (Chief Executive Officers or Chief Marketing Officers) of IC supplier firms. The paper uses partial least squares structural equation modeling (PLS-SEM) and SPSS in analyzing data.

Findings
The results indicate that IC branding is a complex strategy – one involving a number of steps that need to be taken in a specific order. More specifically, results indicate that IC branding starts with EO exerting a positive influence on IC functional differentiation ability (FDA). FDA facilitates reputational differentiation ability (RDA), which in turn encourages the supplier to initiate IC branding.

Originality/value
This paper addresses an important gap by studying the process through, which suppliers initiate IC branding.

PurposeHypertension is a key determinant for the development and progression of chronic kidney disease (CKD). The purpose of this study is to assess the rate of uncontrolled blood pressure (BP) and identify its associated factors in patients with predialysis CKD in Bali, Indonesia.Design/methodology/approachA cross-sectional study was conducted among 165 patients who attended the nephrology clinic in a central public hospital in Bali. Data were obtained by measuring BP at threshold 130/80 mmHg, as well as collected through standardized questionnaires. Univariate analysis was done using Chi-square test, and multivariate analyses were carried out using multiple logistic regression.FindingsA total of 165 patients (111 males and 54 females) with predialysis CKD participated in this study. About 64% of the participants had uncontrolled BP. In multiple logistic regression, all selected variables significantly explained 63.2% of the variance in uncontrolled BP. However, low physical activity (odds ratio [OR] = 24.287, 95% confidence interval [CI]: 3.114–189.445), unhealthy dietary pattern (OR = 10.153, 95% CI: 2.770–37.210), as well as perceived moderate stress (OR = 4.365, 95% CI: 1.024-18.609) and high stress (OR = 10.978, 95% CI: 2.602–46.312) were significantly associated with uncontrolled BP.Research limitations/implicationsThe study findings provide evidence for health care providers to improve BP control among patients with predialysis CKD.Originality/valueControlling BP among patients with predialysis CKD was poor. Lifestyle modification and stress management are keys to improving BP control.
STEM academic achievement and perceptions of family support: a gender analysis
Authors: Smith Daniella LaShaun , Tyler–Wood Tandra L. 
Published: April 2020

PurposeThis study examines the results of a STEM unit taught in an elementary school library, with 26 fourth-grade students as the participants.Design/methodology/approachA quasi-experimental design was used. The relationships between the independent variable gender and the perceptions of familial support structures and academic achievement were examined.FindingsFor the entire group, the average academic achievement scores of the participants increased. The increase was not statistically significant. The male students had a statistically significant improvement in their academic achievement scores, and there was a statistically significant decrease in the academic achievement scores of the female students. An increase in the female students' belief that their family was interested in their science classes was correlated with a decrease in their academic achievement scores.Research limitations/implicationsThe sample size for this study is small, and the results are not generalizable. Open-ended questions were not included in the data collection instruments. Therefore, it cannot be determined why the overall academic scores may have decreased for female students. Further research is encouraged.Practical implicationsThe results of this study show the potential for STEM activities in school libraries. School librarians can provide students with low-risk, informal learning environments to practice new skills.Social implicationsLibraries equalize the availability of resources that otherwise may not be available to populations underrepresented in STEM careers. School librarians have the potential to serve as much needed STEM role models. The availability of STEM activities in school libraries can make it possible for more students to understand what STEM careers are interesting to them.Originality/valueThere are very few studies to examine the results of STEM activities implemented in school libraries that use quasi-experimental or experimental research designs. This study adds to the corpus of research that can be used to support the preparation of students for STEM careers with activities in school libraries.

Authors: Lin Chieh-Peng , Huang Her-Ting , Huang Tse Yao 
Published: April 2020

PurposeDrawing upon social exchange theory, this study justified the indirect effects of responsible leadership and knowledge sharing on job performance through the mediation of work engagement and helping initiatives. Job tenure was examined as a moderator.Design/methodology/approachThe hypotheses of this study were empirically tested with structural equation modeling (SEM) and moderated regression analyses. This study conducted a field survey on 512 knowledge workers who employed a high portion of or highly specialized tacit knowledge to do their job.FindingsThis research presented that both work engagement and helping initiatives mediated the indirect effects of responsible leadership and knowledge sharing on job performance. The empirical results revealed that job tenure moderated the relationships between responsible leadership and work engagement, and between responsible leadership and helping initiatives. However, job tenure did not moderate the relationships between knowledge sharing and work engagement, and between knowledge sharing and helping initiatives.Originality/valueThis research is one of the few to verify the key role of responsible leadership from the theoretical aspect of social exchange, complementing the leadership literature based on stakeholder theory. This research is a pioneer by taking into account the simultaneous influences of responsible leadership and knowledge sharing on job performance in a single model setting.
Deep exploration using long‐offset transient electromagnetics: interpretation of field data in time and frequency domain

Published: April 2020

ABSTRACTIn the framework of the Deep Electromagnetic Soundings for Mineral Exploration project, we conducted ground‐based long‐offset transient‐electromagnetic measurements in a former mining area in eastern Thuringia, Germany. The large‐scale survey resulted in an extensive dataset acquired with multiple high‐power transmitters and a high number of electric and magnetic field receivers. The recorded data exhibit a high data quality over several decades of time and orders of magnitude. Although the obtained subsurface models indicate a strong multi‐dimensional subsurface with variations in resistivity over three orders of magnitude, the electrical field step‐on transients are well fitted using a conventional one‐dimensional inversion. Due to superimposed induced polarization effects, the transient step‐off data are not interpretable with conventional electromagnetic inversion. For further interpretation in one and two dimensions, a new approach to evaluate the long‐offset transient‐electromagnetic data in frequency domain is realized. We present a detailed workflow for data processing in both domains and give an overview of technical obstructions that can occur in one domain or the other. The derived one‐dimensional inversion models of frequency‐domain data show strong multi‐dimensional effects and are well comparable with the conventional time domain inversion results. To adequately interpret the data, a 2.5D frequency‐domain inversion using the open source algorithm MARE2DEM (Modeling with Adaptively Refined Elements for 2‐D EM) is carried out. The inversion leads to a consistent subsurface model with shallow and deep conductive structures, which are confirmed by geology and additional geophysical surveys.

Abstract

Atlantic salmon in aquaculture act as reservoir hosts and vectors of parasites like salmon lice and this parasite is shown to harm wild salmonid populations.

In this study, n = 29,817 tagged Atlantic salmon were studied in four release trials. Half of the released fish were given prophylactic treatment against lice, the other half represented sham control fish. We used a nested design comparing years with low and high lice density and seasonal dynamics in infestation pressure. The released Atlantic salmon thus experienced highly variable lice infestation pressures, which we linked to survival and growth in returning fish. The fish were released in a protected ‘National Salmon Fjord’ and n = 559 Atlantic salmon were recaptured after spending 1–4 years at sea.

In most experimental groups 1%–2.5% of the fish were recaptured at return. However, survival of unprotected fish was extremely low for the trial released at the highest density of lice: only 0.03% of these Atlantic salmon returned to the river, compared to 1.86% in the protected group.

Synthesis and applications. We document that high lice density can cause more than 50 times higher mortality risk in Atlantic salmon on their sea migration, even in a fjord with protected status. Fine‐tuned and hard‐to‐predict year‐to‐year differences in timing, both for the wild smolt migration and the population build‐up of lice released from aquaculture, means life or death to wild salmon. Management actions such as spatial segregation of farmed fish and lice (e.g. closed farm pens), and/or moving farms away from vulnerable habitats for wild salmonids (fjords and coastal areas), may be needed to ensure sustainable coexistence of wild and farmed Atlantic salmon.

AbstractABO antigens play an important role in solid organ transplantation. Desensitization for ABO incompatibility offers patients awaiting transplant a larger donor pool. The aim of this study was to assess outcome of desensitization using the institutional preconditioning protocol in ABO‐incompatible solid organ transplants. A retrospective analysis of ABO‐incompatible solid organ transplants between October 2015 and June 2018, at a tertiary healthcare center was performed. The preconditioning regimen consisted of immunosuppression and therapeutic apheresis (TA). Pre‐ and post‐TA titers were performed, until a target titer of 8 or below was achieved, at which transplant was performed. Follow‐up data till 1 year was analyzed. A total of 50 ABO‐incompatible solid organ transplantations, including 14 liver transplants and 36 renal transplants were analyzed. The median baseline anti‐A and anti‐B titers were 192 and 256, respectively. A total of 150 therapeutic plasma exchange (TPE) procedures were performed for renal transplant recipients; 19 TPE and eight immunoadsorption procedures (five preoperative and three intraoperative) were performed for liver transplant recipients. Five (10%) patients experienced minor adverse events. Biopsy revealed antibody‐mediated rejection was observed in three cases in the immediate posttransplant phase and in three (6.67%) cases over 1 year. There was one death due to transplant‐associated thrombotic microangiopathy. Graft survival for renal transplant was 100% and death‐censored graft survival for liver transplant was 100%. Despite difficulties, ABO‐incompatible transplants can be performed without antibody‐mediated rejection with the use of an appropriate protocol.
Bayesian weighted inference from surveys

Published: April 2020

SummaryData from large surveys are often supplemented with sampling weights that are designed to reflect unequal probabilities of response and selection inherent in complex survey sampling methods. We propose two methods for Bayesian estimation of parametric models in a setting where the survey data and the weights are available, but where information on how the weights were constructed is unavailable. The first approach is to simply replace the likelihood with the pseudo likelihood in the formulation of Bayes theorem. This is proven to lead to a consistent estimator but also leads to credible intervals that suffer from systematic undercoverage. Our second approach involves using the weights to generate a representative sample which is integrated into a Markov chain Monte Carlo (MCMC) or other simulation algorithms designed to estimate the parameters of the model. In the extensive simulation studies, the latter methodology is shown to achieve performance comparable to the standard frequentist solution of pseudo maximum likelihood, with the added advantage of being applicable to models that require inference via MCMC. The methodology is demonstrated further by fitting a mixture of gamma densities to a sample of Australian household income.
Care experienced young people: Agency and empowerment
Authors: Priestley Andrea 
Published: April 2020

AbstractEmpowerment discourses have become fashionable in current policy and practice relating to young people, including those with care experience. Empowerment, however, is a slippery and contested concept, associated with neo‐liberal discourses. An ecological understanding of agency offers more theoretically nuanced understandings of empowerment, taking account of the complex, temporal and relational factors, upon which empowerment is contingent. This paper utilises data generated through an ‘empowerment group’ for care‐experienced young people; it illustrates how an ecological understanding of agency, as a heuristic, might further understanding of the lives of care‐experienced young people.

AbstractWidespread global declines in shellfish reefs (ecosystem‐forming bivalves such as oysters and mussels) have led to growing interest in their restoration and protection. With restoration projects now occurring on four continents and in at least seven countries, global restoration guidelines for these ecosystems have been developed based on experience over the past two decades. The following key elements of the guidelines are outlined: (a) the case for shellfish reef restoration and securing financial resources; (b) planning, feasibility, and goal setting; (c) biosecurity and permitting; (d) restoration in practice; (e) scaling up from pilot to larger scale restoration, (f) monitoring, (g) restoration beyond oyster reefs (specifically mussels), and (h) successful communication for shellfish reef restoration projects.
Genetic mosaicism in haemophilia: A practical review to help evaluate the risk of transmitting the disease
Authors: Lannoy Nathalie , Hermans Cedric 
Published: April 2020

AbstractApproximately 70% of patients with haemophilia exhibit a clear inheritance pattern, while for the remaining 30%, patients are the first to be diagnosed in their family and are considered sporadic cases. In such a setting, the determination of carrier status and the risk estimation of disease transmission to another child are major challenges for genetic counselling. Large studies have suggested that genetic testing reveals 70% of sporadic patients’ mothers are carriers. In the remaining 30%, in some apparently non‐carrier mothers, the pathogenic variant can be detected as low somatic and gonosomal mosaicism. The significance of mosaic pathogenic variants has thus far been underestimated, since conventional Sanger sequencing and other technology are not sufficiently sensitive. The study of various tissue samples and recent extra‐sensitive molecular methods have now made it easier to detect both single‐nucleotide variants (SNVs) and copy‐number variants (CNVs), at a mosaic level in parents, and to predict the probability of disease recurrence. This review seeks to examine various kinds of mosaicism in haemophilia, including the mechanisms by which they arise and the risk of passing these variants on to the next generation. In addition, we focus on the selection of cell tissues and methods to detect these mosaic variants in the haemophilia setting. Taking into account the high rate of mosaicism in mothers of sporadic cases, we propose a diagnostic flow chart that could facilitate better evaluation of the risk of transmitting haemophilia in genetic and prenatal counselling.

Published: April 2020

AbstractIn this work, MgO‐ZrO2 and MgO‐6YSZ ceramic fibers were prepared with sol‐gel method via electrospinning. Polymorph stability and microstructure evolution of zirconia fibers were fully characterized by X‐ray diffraction, Raman spectra, X‐ray photoelectron spectroscopy, and Scanning electron microscope. The results indicated that tetragonal zirconia for MgO‐ZrO2 was obtained and cubic zirconia could be fully stabilized for MgO‐6YSZ with MgO molar fractions varying from 0.1 to 0.5 at 800°C. Monoclinic phase appeared with MgO molar fractions even up to 0.5 for MgO‐ZrO2 system and partially or fully stabilized zirconia could be achieved for MgO‐6YSZ at 1000°C and 1200°C. Grain size was gradually decreased with increasing of MgO content at 800°C both for MgO‐ZrO2 and MgO‐6YSZ ceramic fibers. The grain size of both systems increased with MgO molar fractions varying from 0.1 to 0.2 and then decreased at higher contents at 1000°C and 1200°C. A discussion on relationship among MgO state and the phase stability and grain size was presented. This work shows surface excess and solid solution of MgO predominantly controlled the phase stability and microstructure evolution of zirconia fibers.
L'économie des plateformes sous l'angle de la géographie ouvrière: comprendre les stratégies d'organisation collective dans le contexte du travail intermédié par les plateformes numériques

Published: April 2020

RésuméL'auteure analyse sous un angle géographique la lutte collective des travailleurs de plateforme. Distinguant deux formes de travail de plateforme (l'offre de services locaux et le microtravail), elle examine leurs caractéristiques spatiales respectives et les stratégies d'organisation collective spécifiques à chacune. À partir de trois démarches de dialogue social (comités d'entreprise, négociation collective et accords multientreprises), elle cherche à comprendre pourquoi chaque catégorie de travailleurs de plateforme choisit telle stratégie plutôt que telle autre. Elle analyse les cadres réglementaires dans lesquels s'inscrivent les luttes collectives de ces travailleurs et les chances de voir cette mobilisation améliorer leurs conditions de travail.

AbstractQuestionFiltering vegetation plot records according to sampling size is an essential methodological step in vegetation studies. In fens, the variation of traditionally used plot sizes seems to limit continental‐scale syntheses following the Braun‐Blanquet approach. Which plot sizes harbour the analogous number of habitat specialists (i.e., diagnostic/indicator species) and capture the main compositional gradients identically?LocationScandinavia, central Europe.MethodsThe data set of fen vegetation plot records was compiled using large databases and categorised into four distinct habitats. For each habitat, semi‐log species–area curves of specialists and other species were fitted using generalised additive models (GAM). In addition, we surveyed 72 sites in a series of plot sizes (0.07, 0.25, 1, 4, 16 m2) where we applied, separately for each plot size, Non‐Metric Multi‐Dimensional Scaling (NMDS) and compared the resulting patterns with Procrustes analysis.ResultsConsistently across different fen habitats, the species–area curves of specialists increased steeply up to the plot size of 1 m2, while increasing negligibly in the plot size range of 1–25 m2. In contrast, the species–area curves of other species displayed mostly linear to linear‐exponential trends. NMDS ordinations of medium (1 and 4 m2) and large plots (16 m2) were the most congruent, while the patterns captured in the ordination of the smallest plots (0.07 m2) differed most from the others.ConclusionsIn fens, plot sizes of at least 1 m2 describe sufficiently the broad‐scale pattern in specialists’ diversity as well as the main environmental gradients. The range of plot sizes of 1–25 m2 may be safely merged in broad‐scale analyses of fen vegetation without introducing substantial bias, at least when compared with other possible uncertainty sources.
Procuring Snakes: Thomas Pennant and recent scholarship in Welsh writing of the long eighteenth century
Authors: Edwards Elizabeth 
Published: April 2020

AbstractThis article surveys recent developments in the field of Welsh writing in English in the long eighteenth century. Drawing on the findings of the research project “Curious Travellers: Thomas Pennant and the Welsh and Scottish Tour 1760‐1815”, it sets new work on Pennant and his networks in the context of ongoing research into a number of fields within eighteenth‐century Wales, including political history, literature and science, Wales's bilingual literary inheritance, place and cartography, gender and sexuality, visual culture, print and manuscript, and the digital turn. It proposes Pennant as a useful but underused point of entry to many of these fields, given the extraordinary range of his writing career.
