Technological capability, relational capability and firms’ performance
Authors: Salisu Yakubu , Abu Bakar Lily Julienti 
Published: September 2019

Purpose
The purpose of this paper is to empirically evaluate the mediating role of learning capability on the relationship between technological capability, relational capability and small and medium enterprises (SMEs) performance in developing economy of Africa.

Design/methodology/approach
A quantitative survey design was employed to collect the data from owner/manager of manufacturing SMEs in Nigeria. Partial least square structural equation model was used in the evaluation of both the measurement and structural models to determine the reliability and validity of the measurement and test the hypotheses, respectively.

Findings
The statistical result indicates a positive relationship between technological capability, learning capability and SMEs performance. Equally, relational capability significantly and positively relates to SMEs learning capability. However, relational capability negatively relates to SMEs performance, while technological capability also negatively relates to learning capability. Furthermore, learning capability mediates the negative relationship of relational capability and SMEs performance to significant positive relationship, while it does not mediate the relationship of technological capability and performance.

Research limitations/implications
The analysis of this study is restricted to only resource-based view and dynamic capability theory. Data of the study were collected once a time on a self-reported technique. The study contributed significantly to the body literature on technological and relational capabilities and performance. It also demonstrated the need for SMEs manager to recognize and appreciate the roles of these strategic capabilities in achieving sustainable competitive position.

Practical implications
Through relational capability SMEs develops efficient collaborative relationship to acquire new techniques, knowledge. This is specifically, essential for SMEs firms from less developing and emerging economies as they are lagging behind at the global competitive platform, and that the possession of specific advantage locally may not be adequately enough to help penetrate the global markets. Similarly, technological capability enable firms to identify acquire and apply new external knowledge to develop operational competencies which may lead to the attainment of superior performance.

Social implications
Government policies and programs designed to support technological development and innovation must be adjusted to consider the peculiar nature of SMEs firms in terms of technology and innovativeness that enhances competitive position and performance.

Originality/value
This study empirically examined the relationship of technological and relational capabilities and the SMEs learning capability and performance.

Purpose
The purpose of this paper is to formally assess the training program received by information studies graduate students and the reference services they provided at a research-intensive university.

Design/methodology/approach
A qualitative content analysis was used to evaluate if graduate students incorporated the training they received in their provision of reference services. The students’ virtual reference transcripts were coded to identify the level of questions asked, if a reference interview occurred and if different teaching methods were used by the students in their interactions. The in-person reference transactions recorded by the students were coded for the level of questions asked.

Findings
The main findings demonstrate a low frequency of reference interviews in chat interactions with a presence in only 23 per cent of instances while showing that instructional methods are highly used by graduate student reference assistants and are present in 66 per cent of chat conversations.

Originality/value
This study is of interest to academic libraries who wish to partner with information studies programs and schools to offer graduate students valuable work experience. It aims to show the value that graduate students can bring to reference services. Furthermore, it highlights the importance of continuously developing training programs and assessing the performance of graduate students working in these roles.
Efficacy of alitretinoin depending on the concomitant use of topical corticosteroids in chronic hand eczema patients
Authors: Cheon Dong Uk , Kim Jeong Eun , Ko Joo Yeon , Ro Young Suck 
Published: September 2019

AbstractAlitretinoin is the only systemic agent approved for the treatment of severe chronic hand eczema (CHE) unresponsive to potent topical corticosteroids. Clinical trials have shown the efficacy of oral alitretinoin with topical emollients for CHE treatment, but most studies have failed to reach a therapeutic success rate of 50%. Reasonably, we thought it would be more effective to combine topical corticosteroids with oral alitretinoin, but the concomitant use of topical corticosteroids has not been studied yet. One‐hundred and seven Korean patients diagnosed with CHE were recruited. The participants were divided into two groups depending on the concomitant use of topical corticosteroids. Comparative analysis was performed between the combined therapy (alitretinoin and topical corticosteroids) and monotherapy groups (alitretinoin only) by using physician global assessment (PGA), patient's global assessment (PaGA), modified total lesion symptom score (mTLSS), and recurrence rates. The combined therapy group showed a significantly higher treatment success rate than the alitretinoin monotherapy group for all efficacy parameters (PGA: P < 0.001, PaGA: P < 0.001, mTLSS changes: P < 0.001), but there was no significant difference in recurrence rates between the groups (P = 0.266). Combined use of topical corticosteroids is recommended for CHE patients being treated with oral alitretinoin due to clinically rapid and superior effectiveness.

Authors: Haselgruber A. , Sölva K. , Lueger‐Schuster B. 
Published: September 2019

ObjectiveICD‐11 introduces post‐traumatic stress disorder (PTSD) and complex PTSD (CPTSD) as two distinct trauma‐related disorders. Using the International Trauma Questionnaire (ITQ) as disorder‐specific measure, this study is the first to examine the factorial and construct validity of ICD‐11 PTSD, CPTSD and the ITQs’ applicability in children.MethodsTwo hundred and eight Austrian foster children completed a set of standardized measures. Excluding participants who reported not having experienced any kind of trauma, a final sample of 136 children completed the ITQ. Factorial and construct validity of ICD‐11 CPTSD and psychometric properties of ITQ scales were assessed by factor analysis and latent class analysis.ResultsConfirmatory factor analysis supported the two‐factor higher‐order model of ICD‐11 CPTSD in children by high factor loadings and excellent model fit. Reliability and regression analysis evidenced psychometric adequacy and discriminant validity of ITQ scales. Latent class analysis substantiated construct validity of ICD‐11 CPTSD, identifying a CPTSD (22.8%), PTSD (31.6%) and low symptoms class (45.6%). The CPTSD class showed highest rates of childhood trauma, comorbid psychopathology and functional impairment.ConclusionFactorial and construct validity of ICD‐11 CPTSD was evidenced in children for the first time using precise descriptions of ICD‐11 symptom content, supporting the reliability and validity of the ITQ in children.

Published: September 2019

Accessible summary

There is a need for more voiced opinions from Special Olympic (SO) athletes in contemporary literature.

Five SO athletes presented their own views on their experiences of participating in sport.

SO athletes would welcome more autonomy, responsibility and roles in their everyday sporting participation.

Implications for coaches and parents are presented as a consequence of sporting involvement.

AbstractBackgroundIn the past, academic literature and research relating to the Special Olympics (SO) have focused mainly on the parents', professionals' and coaches' views, with some concentrating on the effects of SO on athletes' quality of life. Relatively little has concentrated on the athlete's own perspectives. Therefore, this study set out to examine the under‐researched area of SO athletes' opinions of taking part in sporting activities and their satisfaction during training and competition.Materials and MethodsFive athletes from one SO athletic club agreed to take part in the study. Thematic analysis was used for generating themes in relation to participants' responses.ResultsFour themes were identified: (a) platform for voice; (b) intense emotions; (c) social reasons to participate; and (d) nutrition, health and sport.ConclusionsSO athletes' views suggest the need for changes in practice during training and competition. Recommendations are made with the view to further support SO athletes' needs.

AbstractHashimoto encephalopathy (HE) is an autoimmune encephalopathy associated with autoimmune chronic thyroiditis. The clinical entity and nosology of HE have long been debated. Recently, new autoantibodies associated with autoimmune encephalitis have been discovered. With accumulated reported cases, and our discovery of serum autoantibody against NH2‐terminal of alpha‐enolase as a specific diagnostic marker, HE has been recognized as a distinct clinical entity. The condition appears dominant in females. The clinical features of HE are characterized by various neuropsychiatric symptoms, such as altered consciousness, psychosis and seizures, the presence of serum anti‐thyroid antibodies, normal or non‐specific changes in brain magnetic resonance imaging, diffuse slow wave activities in electroencephalogram and responsiveness to immunotherapy. A few pathological studies showed a lymphocytic infiltration of the small and medium‐sized vessels of the brain, which suggested vasculitis. Non‐specific neurological symptoms, laboratory findings and neuroimaging of HE make its diagnosis an oversight and difficult, whereas antibodies against NH2‐terminal of alpha‐enolase can be useful as a diagnostic biomarker for HE. In this review, we describe the current state of knowledge about HE and discuss progress in the diagnosis of HE.

AbstractAimsTo evaluate the percentage of women with untreated fasting hyperglycaemia in early pregnancy who develop gestational diabetes mellitus after 22 weeks’ gestation, the determinants of gestational diabetes development in such women and the prognosis of early fasting hyperglycaemia according to whether the women go on to develop gestational diabetes.MethodsFrom a large cohort of women who delivered in our hospital between 2012 and 2016, we retrospectively selected all those who had untreated early fasting hyperglycaemia and separated them into a ‘gestational diabetes’ and a ‘no‐gestational diabetes’ group according to oral glucose tolerance test results after 22 weeks’ gestation. We compared the incidence of a predefined composite outcome (preeclampsia or large‐for‐gestational‐age infant or shoulder dystocia or neonatal hypoglycaemia) in both groups.ResultsA total of 268 women (mean fasting plasma glucose 5.3 ± 0.3 mmol/l at a mean ± sd of 10.2 ± 4.2 weeks’ gestation) were included. Gestational diabetes developed in 134 women and was independently associated with early fasting plasma glucose ≥ 5.5 mmol/l [odds ratio 3.16 (95% CI 1.57, 6.33)], age ≥ 30 years [odds ratio 2.78 (95% CI 1.46, 5.31)], preconception obesity [odds ratio 2.12 (95% CI 1.11, 4.02)], family history of diabetes [odds ratio 1.87 (95% CI 1.00, 3.50)] and current employment [odds ratio 0.46 (95% CI 0.26, 0.83)]. Despite treatment, gestational diabetes induced a significant increase in the composite outcome as compared to no gestational diabetes (odds ratio 2.16 [95% CI 1.08, 4.34]). The association disappeared after adjustment for risk factors.ConclusionsOnly half of the women with early fasting hyperglycaemia and no specific care subsequently developed gestational diabetes, and these women had a poor prognosis despite gestational diabetes treatment. Poor prognosis was mostly attributable to risk factors. Our results suggest that only women with certain risk factors should be screened for early fasting hyperglycaemia.

Background and purposeThe rate at which the chance of a good outcome of endovascular stroke therapy (EVT) decays with time when eligible patients are selected by baseline diffusion‐weighted magnetic resonance imaging (DWI‐MRI) and whether ischaemic core size affects this rate remain to be investigated.MethodsThis study analyses a prospective multicentre registry of stroke patients treated with EVT based on pretreatment DWI‐MRI that was categorized into three groups: small [Diffusion‐Weighted Imaging Alberta Stroke Program Early Computed Tomography Score (DWI‐ASPECTS)] (8–10), moderate (5–7) and large (<5) cores. The main outcome was a good outcome at 90 days (modified Rankin Scale 0–2). The interaction between onset‐to‐groin puncture time (OTP) and DWI‐ASPECTS categories regarding functional outcomes was investigated.ResultsUltimately, 985 patients (age 69 ± 11 years; male 55%) were analysed. Potential interaction effects between the DWI‐ASPECTS categories and OTP on a good outcome at 90 days were observed (Pinteraction = 0.06). Every 60‐min delay in OTP was associated with a 16% reduced likelihood of a good outcome at 90 days amongst patients with large cores, although no associations were observed amongst patients with small to moderate cores. Interestingly, the adjusted rates of a good outcome at 90 days steeply declined between 65 and 213 min of OTP and then remained smooth throughout 24 h of OTP (Pnonlinearity = 0.15).ConclusionsOur study showed that the probability of a good outcome after EVT nonlinearly decreased, with a steeper decline at earlier OTP than at later OTP. Discrepant effects of OTP on functional outcomes by baseline DWI‐ASPECTS categories were observed. Thus, different strategies for EVT based on time and ischaemic core size are warranted.

AimTo determine the prevalence of dementia in the past two decades and provide updated estimates about older people (aged ≥60 years) with dementia in China from 2015 to 2050.MethodsThe English and Chinese databases were retrieved. Published epidemiology surveys of dementia from 1990–2018 were screened. Meta‐analysis was used to calculate their pooled prevalence. The age‐moving method was used to estimate the population aged ≥60 years in 2020, 2030, 2040 and 2050 based on the data of the sampling survey of 1% of the population in 2015 released by the National Bureau of Statistics. The pooled prevalence of three age groups (60–69, 70–79, ≥80 years) from 2015 to 2018 was used as the basis to estimate the number of older people with dementia.ResultsThe pooled prevalence rate of dementia in Mainland China from 1985 to 2018 was 4.9% (95% CI 4.3–5.4), and the prevalence rate from 2015 to 2018 among them was 7.4% (95% CI 5.3–9.5). In 2020, 2030, 2040 and 2050, the number of people with dementia will be 16.93 million, 24.25 million, 31.98 million and 35.98 million, respectively. Furthermore, people with dementia aged ≥60 years in 2050 will be 2.13‐fold than that of 2015.ConclusionThe number of dementia patients in China will increase dramatically in the next 30 years without preventive measures.

Published: September 2019

BackgroundATP‐sensitive potassium (KATP) channel opener levcromakalim induces migraine attacks in migraine patients. Underlying mechanisms responsible for headache and migraine induction after levcromakalim infusion are unknown.ObjectiveTo investigate the effect of levcromakalim on the cranial arteries and to explore the possible relationship between the middle meningeal artery (MMA) dilation and headache.MethodsIn a double‐blind, randomized, placebo‐controlled study, 20 healthy volunteers were scanned at the baseline and repeatedly after infusion of levcromakalim (n = 14) and placebo (n = 6). All participants received a subcutaneous injection of sumatriptan 6 mg before the last scanning.ResultsThe MMA circumference was significantly larger after levcromakalim compared with placebo (P < .0001). The MMA dilation lasted over 5 hours during observational period. We found a significant association between headache and MMA dilation (P < .0001). The superficial temporal artery (STA) circumference was significantly larger after levcromakalim compared with placebo (P = .03) over the initial period (110 minutes). Over the entire observational period, there was no difference in circumference of the STA and the middle cerebral artery (MCA) between levcromakalim and placebo.ConclusionLevcromakalim dilated the MMA but not MCA. The MMA dilation was associated with headache. Future studies should investigate whether opening of KATP channels can activate and sensitize the perivascular nociceptors.

Published: September 2019

AbstractAimsTo investigate the effect of defect morphology, bone thickness and examiner experience on the accuracy to detect the presence, the type and the depth of peri‐implant defects with digital periapical radiographs (PAs) and cone beam computed tomography (CBCT) in an in vitro model.MethodsThirty six implants were placed in fresh porcine rib bone with different types of standardized defects while sites with no defect served as control. Fourteen masked examiners evaluated 324 PAs and 108 CBCT images. The presence and type of defect, the location of the bottom of the defect and the location of first bone‐to‐implant contact were recorded. The sensitivity, specificity, accuracy, positive and negative predictive values were calculated for each type of defect using actual measurements as the gold standard.ResultsThe diagnostic accuracy for PAs was affected by defect morphology, exposure time, thickness of bone walls and the level of experience of the examiner. The overall diagnostic accuracy of CBCT was high (>96%) for all types of defects.ConclusionCone beam computed tomography showed better diagnostic accuracy in the detection of peri‐implant defects, this can be attributed to the fact that CBCT seems to be less affected by variables that contribute to the poorer performance of PAs.

BackgroundParenting programs suitable for delivery at scale in low‐resource contexts are urgently needed. We conducted a randomized trial of Parenting for Lifelong Health (PLH) for Young Children, a low‐cost 12‐session program designed to increase positive parenting and reduce harsh parenting and conduct problems in children aged 2–9.MethodsTwo hundred and ninety‐six caregivers, whose children showed clinical levels of conduct problems (Eyberg Child Behavior Inventory Problem Score, >15), were randomly assigned using a 1:1 ratio to intervention or control groups. At t0, and at 4–5 months (t1) and 17 months (t2) after randomization, research assistants blind to group assignment assessed (through caregiver self‐report and structured observation) 11 primary outcomes: positive parenting, harsh parenting, and child behavior; four secondary outcomes: parenting stress, caregiver depression, poor monitoring/supervision, and social support. Trial registration: ClinicalTrials.gov (NCT02165371); Pan African Clinical Trial Registry (PACTR201402000755243); Violence Prevention Trials Register (http://www.preventviolence.info/Trials?ID=24).ResultsCaregivers attended on average 8.4 sessions. After adjustment for 30 comparisons, strongest results were as follows: at t1, frequency of self‐reported positive parenting strategies (10% higher in the intervention group, p = .003), observed positive parenting (39% higher in the intervention group, p = .003), and observed positive child behavior (11% higher in the intervention group, p = .003); at t2, both observed positive parenting and observed positive child behavior were higher in the intervention group (24%, p = .003; and 17%, p = .003, respectively). Results with p‐values < .05 prior to adjustment were as follows: At t1, the intervention group self‐reported 11% fewer child problem behaviors, 20% fewer problems with implementing positive parenting strategies, and less physical and psychological discipline (28% and 14% less, respectively). There were indications that caregivers reported 20% less depression but 7% more parenting stress at t1. Group differences were nonsignificant for observed negative child behavior, and caregiver‐reported child behavior, poor monitoring or supervision, and caregiver social support.ConclusionsPLH for Young Children shows promise for increasing positive parenting and reducing harsh parenting.
