Published: May 2023

PurposeBrain-drain insurgency has become pervasive amongst professionals and the last option for everyone in the country to realise a sustainable quality of work-life (QWL). All youths now in the country have perceived migrating to the international workspace as a noble idea. This study investigates the incidence of brain-drain and QWL amongst academics in Nigerian universities.Design/methodology/approachTo sparkle a clearer understanding concerning factors preventing the QWL amongst Nigeria's lecturers, this study utilised a cross-sectional research design to survey the participants across all departments in federal institutions through an explanatory research approach. This study applied an array of adapted scales to evaluate members of academic staff track of what provoked the incidence of brain-drain amongst Nigerian lecturers and possible influence on their QWL. The study surveyed 431 members of academic staff in Nigerian universities to collect useful data and employed a structural equation model (SEM) to analyse the obtained data.FindingsThe outcome of this study highlights that there is a horrible condition of service amongst Nigerian lecturers, a poor compensation system, poor academic research funding and lack of autonomy are bane to the QWL experienced in Nigerian tertiary institutions today. This study indicates that poor staff development and inadequate university funding are part of the justification that provoked brain-drain insurgence, and allowed the government to lose their skilled and competent egg-heads in the university to other foreign nations of the world.Originality/valueThis study demonstrated that brain-drain has become part of Nigeria's national life given that all professionals are seeking better life where their skills, competence and energy would be valued. Brain-drain was not common until these days amongst academics and fewer studies were noted but this study showed a novel paradigm regarding the QWL and brain-drain trajectory.

Published: May 2023

Purpose
This paper aims to determine whether there is a relationship between intellectual capital and social capital and internal control weaknesses and assess the relationship between the variables of intellectual capital and social capital and internal control weaknesses.

Design/methodology/approach
The statistical population consists of 1,309 firm-year observations from 2014 to 2020. The research hypothesis is tested using statistical methods, including multivariate, least-squares and fixed-effects regression.

Findings
The results demonstrate a negative and significant relationship between intellectual capital, social capital and internal control weaknesses. The study also finds that increased intellectual and social capital quality improves human resource utilization, control mechanism, creativity and firm performance. The results also show that intellectual capital and social capital enhancement will reduce internal control weaknesses in the upcoming years.

Originality/value
This paper is the pioneer study on the relationship between intellectual capital and social capital and internal control weaknesses in Iran, carried out separately and in exploratory factor analysis. This paper considers intellectual capital components for theoretical factor analysis, including human capital, structural capital and customer capital. Internal control weakness is assessed based on financial, non-financial and information technology (IT) weaknesses.

Published: May 2023

PurposeThis study aims to investigate the influence of supply chain resilience (SCR) and supply chain capabilities (SCC) on supply chain performance (SCP) through the direct and moderating influence of the degree of SCR (DSCR), as demonstrated in UAE energy industry supply chain management (SCM) processes.Design/methodology/approachUsing the partial least squares structural equation modeling (PLS-SEM), a questionnaire-survey collected 168 valid responses from UAE-based companies that operate within the energy industry. This study investigates the moderated mediation research model of the SCR, SCC and SCP with DSCR being considered as the variable having the moderation role.FindingsSCR and SCC were found to have a significant positive affect on SCP playing a mediating role in improving performance during or after a SC disruption. However, the objective was to confirm the exitance of the moderator role in DSCR to substantiate its moderated mediating effect in the research model. There was a negative moderating effect of SCR on SCP through SCC.Originality/valueThis is among the pioneer study that suggests and empirically tests the moderated mediating impacts of the SCR degree on the relationships between SCR, capability within a supply chain and its performance. An additional element of originality of this study is its relevance to the UAE energy industry and recent SC disruptions.

Authors: Jingbo Xu , Qiaowei Li , Bai White 
Published: May 2023

Purpose
The purpose of this study is solving the hand–eye calibration issue for line structured light vision sensor. Only after hand–eye calibration the sensor measurement data can be applied to robot system.

Design/methodology/approach
In this paper, the hand–eye calibration methods are studied, respectively, for eye-in-hand and eye-to-hand. Firstly, the coordinates of the target point in robot system are obtained by tool centre point (TCP), then the robot is controlled to make the sensor measure the target point in multiple poses and the measurement data and pose data are obtained; finally, the sum of squared calibration errors is minimized by the least square method. Furthermore, the missing vector in the process of solving the transformation matrix is obtained by vector operation, and the complete matrix is obtained.

Findings
On this basis, the sensor measurement data can be easily and accurately converted to the robot coordinate system by matrix operation.

Originality/value
This method has no special requirement for robot pose control, and its calibration process is fast and efficient, with high precision and has practical popularized value.

Published: May 2023

BackgroundA significant portion of adults struggle to read at a basic level. Word reading (defined here as decoding and word recognition) appears to play a pivotal role for this population of readers; however, less is known about how word reading relates to other important semantic processes (e.g., vocabulary, sentence processing) known to account for a large portion of variance in reading comprehension. This study used the Reading Systems Framework to explore the extent that moderational and mediational relations existed between word reading and semantic processing abilities in predicting reading comprehension.MethodsParticipants (N = 169) completed the Reading Inventory and Scholastic Evaluation, which consists of a series of subtests intended to measure decoding/word recognition, vocabulary, sentence processing and reading comprehension.ResultsA moderated mediation model was constructed to assess the extent to which moderational and mediational relations between word reading and semantic processing were predictive of comprehension. Results suggested that word reading moderated the effect of vocabulary knowledge on comprehension among struggling adult readers. Additionally, semantic processing at the word (i.e., vocabulary) and sentence level both significantly mediated the relation between word reading and comprehension.ConclusionsWord reading moderated the relation between vocabulary and comprehension for struggling adult readers. Readers with greater word reading ability benefited most from having a higher degree of vocabulary knowledge. Vocabulary and sentence processing mediated the relation between word reading and comprehension. Thus, word reading appears to serve as an important gateway for struggling readers, and, as such, interventions targeting component skills of reading may have a limited impact on reading literacy tasks until word reading skills are developed.

ObjectivesPortal venous thrombosis (PVT) in cirrhotic patients is usually asymptomatic and diagnosed incidentally. In this study we aimed to investigate the prevalence and characteristics of advanced PVT in cirrhotic patients with a recent episode of gastroesophageal variceal hemorrhage (GVH).MethodsCirrhotic patients with recent GVH at one month before their admission for further treatment to prevent rebleeding were retrospectively recruited. Hepatic venous pressure gradient (HVPG) measurements, contrast‐enhanced computed tomography (CT) scan of the portal vein system, and endoscopy were performed. PVT was diagnosed by CT examination and classified as none, mild and advanced.ResultsOf the 356 patients enrolled, 80 (22.5%) had advanced PVT. Elevated levels of white blood cells (WBC) and serum D‐dimer were observed in advanced PVT patients compared with those with no or mild PVT. Moreover, HVPG was lower in patients with advanced PVT, with fewer patients having HVPG exceeding 12 mmHg, while grade III esophageal varices and varices with red signs were more prevalent. Multivariate analysis showed that WBC count (odds ratio [OR] 1.401, 95% confidence interval [CI] 1.171–1.676, P < 0.001), D‐dimer level (OR 1.228, 95% CI 1.117–1.361, P < 0.001), HVPG (OR 0.942, 95% CI 0.900–0.987, P = 0.011), and grade III esophageal varices (OR 4.243, 95% CI 1.420–12.684, P = 0.010) were associated with advanced PVT.ConclusionsAdvanced PVT, which is associated with a more severe hypercoagulable and inflammatory status, causes severe prehepatic portal hypertension in cirrhotic patients with GVH.

AbstractBackgroundArthroplasty patients are at high risk of hypothermia. Pre‐warming with forced air has been shown to reduce the incidence of intraoperative hypothermia. There is, however, a lack of evidence that pre‐warming with a self‐warming (SW) blanket can reduce the incidence of perioperative hypothermia. This study aims to evaluate the effectiveness of an SW blanket and a forced‐air warming (FAW) blanket peri‐operatively. We hypothesised that the SW blanket is inferior to the FAW blanket.MethodsIn total, 150 patients scheduled for primary unilateral total knee arthroplasty under spinal anaesthesia were randomised to this prospective study. Patients were pre‐warmed with SW blanket (SW group) or upper‐body FAW blanket (FAW group) set to 38°C for 30 min before spinal anaesthesia induction. Active warming was continued with the allocated blanket in the operating room. If core temperature fell below 36°C, all patients were warmed using the FAW blanket set to 43°C. Core and skin temperatures were measured continuously. The primary outcome was core temperature on admission to the recovery room.ResultsBoth methods increased mean body temperature during pre‐warming. However, intraoperative hypothermia occurred in 61% of patients in the SW group and in 49% in the FAW group. The FAW method set to 43°C could rewarm hypothermic patients. Core temperature did not differ between groups on admission to the recovery room, p = .366 (CI: −0.18–0.06).ConclusionsStatistically, the SW blanket was non‐inferior to the FAW method. Yet, hypothermia was more frequent in the SW group, requiring rescue warming as we strictly held to the NICE guideline.Trial RegistrationClinicaltrials.gov identifier: NCT03408197.

AbstractBackgroundVentilator‐induced diaphragm dysfunction occurs rapidly following the onset of mechanical ventilation and has significant clinical consequences. Phrenic nerve stimulation has shown promise in maintaining diaphragm function by inducing diaphragm contractions. Non‐invasive stimulation is an attractive option as it minimizes the procedural risks associated with invasive approaches. However, this method is limited by sensitivity to electrode position and inter‐individual variability in stimulation thresholds. This makes clinical application challenging due to potentially time‐consuming calibration processes to achieve reliable stimulation.MethodsWe applied non‐invasive electrical stimulation to the phrenic nerve in the neck in healthy volunteers. A closed‐loop system recorded the respiratory flow produced by stimulation and automatically adjusted the electrode position and stimulation amplitude based on the respiratory response. By iterating over electrodes, the optimal electrode was selected. A binary search method over stimulation amplitudes was then employed to determine an individualized stimulation threshold. Pulse trains above this threshold were delivered to produce diaphragm contraction.ResultsNine healthy volunteers were recruited. Mean threshold stimulation amplitude was 36.17 ± 14.34 mA (range 19.38–59.06 mA). The threshold amplitude for reliable nerve capture was moderately correlated with BMI (Pearson's r = 0.66, p = 0.049). Repeating threshold measurements within subjects demonstrated low intra‐subject variability of 2.15 ± 1.61 mA between maximum and minimum thresholds on repeated trials. Bilateral stimulation with individually optimized parameters generated reliable diaphragm contraction, resulting in significant inhaled volumes following stimulation.ConclusionWe demonstrate the feasibility of a system for automatic optimization of electrode position and stimulation parameters using a closed‐loop system. This opens the possibility of easily deployable individualized stimulation in the intensive care setting to reduce ventilator‐induced diaphragm dysfunction.

Published: May 2023

AbstractBackgroundChildren and young people experience various transitions throughout their education. Theory and evidence highlight that these can be complex, and poor experiences of transitions can be associated with worsened outcomes, necessitating a need to develop and implement wellbeing support. However, children and young people's views are lacking in the literature, and studies tend to focus on specific transitions rather than on what matters for wellbeing during transitions generally.AimsWe explore children and young people's own perceptions of what would support wellbeing during educational transitions.SampleWe engaged with 49 children and young people aged 6–17 years, using purposeful maximum variation sampling to facilitate engagement of a diverse sample across a variety of education setting types.MethodsWe undertook focus groups, using creative methods centred around a storybook, asking participants to make decisions as headteachers about wellbeing provision in a fictional setting. Data were analysed using reflexive thematic analysis.AnalysisWe constructed four themes: (1) helping children and young people understand what to expect; (2) developing and sustaining relationships and support; (3) being responsive to individual needs and vulnerabilities; and (4) managing loss and providing a sense of closure.ConclusionsOur analysis highlights a desire among children and young people for a considered, supportive approach that recognizes their individual needs and their connection to educational communities. The study makes a methodological and conceptual contribution, demonstrating the value of adopting a multifocussed lens to researching and supporting transitions.

AbstractCongenital erythrocytoses represent a heterogenous group of rare defects of erythropoiesis characterized by elevated erythrocyte mass. We performed molecular‐genetic analysis of 21 Czech patients with congenital erythrocytosis and assessed the mutual link between chronic erythrocyte overproduction and iron homoeostasis. Causative mutations in erythropoietin receptor (EPOR), hypoxia‐inducible factor 2 alpha (HIF2A) or Von Hippel–Lindau (VHL) genes were detected in nine patients, including a novel p.A421Cfs*4EPORand a homozygous intronic c.340+770T>CVHLmutation. The association and possible cooperation of five identified missense germlineEPORor Janus kinase 2 (JAK2) variants with other genetic/non‐genetic factors in erythrocytosis manifestation may involve variants of Piezo‐type mechanosensitive ion channel component 1 (PIEZO1) or Ten‐eleven translocation 2 (TET2), but this requires further research. In two families, hepcidin levels appeared to prevent or promote phenotypic expression of the disease. No major contribution of heterozygous haemochromatosis gene (HFE) mutations to the erythrocytic phenotype or hepcidin levels was observed in our cohort.VHL‐ andHIF2A‐mutant erythrocytosis showed increased erythroferrone and suppressed hepcidin, whereas no overproduction of erythroferrone was detected in other patients regardless of molecular defect, age or therapy. Understanding the interplay between iron metabolism and erythropoiesis in different subgroups of congenital erythrocytosis may improve current treatment options.
Increase in physiological inhibitory control results in better suppression of unwanted memories
Authors: Gunduz Turan , Gunduz Hasan , Cetinkaya Hakan 
Published: May 2023

AbstractForgetting or suppressing a memory with unwanted content is just as important as remembering a desirable one. In addition to emphasizing the role of inhibitory control in memory suppression processes, neuropsychological studies have indicated that an intentional inhibition targeting a brain area may exert its inhibitory effects in seemingly unrelated areas through a common inhibitory network. In this study, we aimed to investigate whether the suppression of unwanted memories can be strengthened by recruiting an inhibitory task that can be simultaneously performed with a memory suppression task. Therefore, we manipulated the level of urinary urgency‐induced inhibition of participants (N = 180) and test its effect on the suppression of unwanted memories using a Think/No‐Think (T/NT) task. The results of our study indicated that individuals with high levels of urinary urgency demonstrated greater memory suppression compared to those with low urinary urgency. Findings and their implications are discussed within the context of cognitive and clinical perspectives, and recommendations are made for future research.

ObjectiveTo provide insight into the use and staging information on lymph‐node involvement added by fluorodeoxyglucose‐positron emission tomography/computed tomography (FDG‐PET/CT) in patients with muscle‐invasive bladder cancer (MIBC), based on a nationwide population‐based cohort study.Patients and methodsWe analysed a nationwide cohort of patients with MIBC without signs of distant metastases, newly diagnosed in the Netherlands between November 2017 and October 2019. From this cohort, we selected patients who underwent pre‐treatment staging with CT only or CT and FDG‐PET/CT. The distribution of patients, disease characteristics, imaging findings, nodal status (clinical nodal stage cN0 vs cN+) and treatment were described for each imaging modality group (CT only vs CT and FDG‐PET/CT).ResultsWe identified 2731 patients with MIBC: 1888 (69.1%) underwent CT only; 606 (22.2%) underwent CT and FDG‐PET/CT, 237 (8.6%) underwent no CT. Of the patients who underwent CT only, 200/1888 (10.6%) were staged as cN+, vs 217/606 (35.8%) who underwent CT and FDG‐PET/CT. Stratified analysis showed that this difference was found in patients with clinical tumour stage (cT)2 as well as cT3/4 MIBC. Of patients who underwent both imaging modalities and were staged with CT as cN0, 109/498 (21.9%) were upstaged to cN+ based on FDG‐PET/CT. Radical cystectomy (RC) was the most common treatment within both imaging groups. Preoperative chemotherapy was more frequently applied in cN+ disease and in FDG‐PET/CT‐staged patients. Concordance of pathological N stage after upfront RC was higher among patients staged as cN+ with CT and FDG‐PET/CT (50.0% pN+) than those staged as cN+ with only CT (39.3%).ConclusionPatients with MIBC who underwent pre‐treatment staging with FDG‐PET/CT were more often staged as lymph node positive, regardless of cT stage. In patients with MIBC who underwent CT and FDG‐PET/CT, FDG‐PET/CT led to clinical nodal upstaging in approximately one‐fifth. Additional imaging findings may influence subsequent treatment strategies.
