Organizational social capital, resilience and innovation validation of a theoretical model for specialized workers
Authors: Fandiño Antonio Martinez , Formiga Nilton Soares , de Menezes Rui Manuel 
Published: November 2018

PurposeThe purpose of this paper is to understand the interactions and their cause/effect consequences of three aspects present inside organizational realities, namely, organizational social capital (OSC), worker resilience and innovation derived from the workers.Design/methodology/approachA cross-sectional study for analyzing the subjects was chosen. As a quantitative research approach, after the theoretical review, two possibilities were hypothesized for how they act as a system. In order to verify the hypotheses, the authors chose the structural equation model, a suitable instrument for this analysis, as a mathematical tool.FindingsThe results show that OSC is a mediator between resilience and innovation in the organizational dynamics. This suggests that workers’ resilience need OSC, acting as the mediator, to improve their level of innovation capacity.Research limitations/implicationsThe study gives information at a specific point in time. Follow-up studies are needed to understand the phenomena’s transformation, and no distinction was made between exploratory and exploitative innovation. More empirical studies should be carried out to enhance its understanding.Practical implicationsThese findings can help organizations deal better with these resources to reach their goals because the first, as stated in the purpose, is the amalgamated goodwill necessary for individuals to work together; the second is workers’ capacity to bounce back; and the last is the creativity inherent in people. All of which are significant for an enterprise thrive in its market.Originality/valueThe cited dynamic has few studies, and this work provides evidence about its existence and magnitude, shedding light on a critical factors’ relationship net, especially for enterprises based on the creativity of their workers.
Antecedents of co-development and its effect on innovation performance
Authors: Tsou Hung-Tai , Chen Ja-Shen , Yu Ya-Wen (Diana) 
Published: November 2018

PurposeIn the contemporary business environment, companies must constantly consider methods to enhance their competitive advantage and create value for their customers. The purpose of this paper is to develop a research model based on a business ecosystem view. Within a business ecosystem, the authors identified the key factors of co-development and the manner in which these factors affect a company’s innovation performance.Design/methodology/approachThe theoretical hypotheses are confirmed by partial least squares analysis of survey responses collected from information and communication technology (ICT) and hotel industries in Taiwan.FindingsIn both industries, the results suggest that a firm’s co-development within its own ecosystem has positive effects on innovation performance. For companies in the ICT industry, collaborative networks and partner selection have significant impacts on the firms’ co-development, but their information technology (IT) capability does not; in contrast, in the hotel industry, partner selection and IT capability have significant impacts on firm co-development, but their collaborative network does not.Originality/valueThis study contributes to the literature of business ecosystem and co-development by offering a co-development model. As both conceptual and empirical research on this topic is still underdeveloped, this study provides fresh insights into collaboration management and offers significant theoretical and managerial implications from a business ecosystem perspective.
Developing a model for supply chain agility and innovativeness to enhance firms’ competitive advantage
Authors: Chen Chih-Jou 
Published: November 2018

Purpose
Developing agility and innovativeness as dynamic capabilities are important for firms to sustain their competitive advantage in today’s global economy. The purpose of this paper is to develop and empirically test a framework to investigate how the supply chain agility and innovativeness are achieved through IT integration and trust in members of supply chain and how these, in turn, can enhance firms’ competitive advantage.

Design/methodology/approach
This research employs a survey method and data are collected from senior managers working in the supply chain or IT area. The model and hypotheses are tested utilizing data from 204 usable Taiwan manufacturing firms via structural equations modeling methodology.

Findings
The study demonstrates that both IT integration and trust in supply chain members significantly enhance supply chain agility and innovativeness, which in turn positively affect firm’s competitive advantage. The results indicate that IT integration and trust are antecedents and major joint partnership resources for improving supply chain agility and innovativeness.

Research limitations/implications
Data are collected from manufacturing industry in Taiwan and single respondent from each firm, the generalizability of current findings to other industries or countries should require additional investigation.

Practical implications
The study suggests that a firm should focus on IT integration and trust in supply chain members to achieve supply chain agility and innovativeness. To take advantage of supply chain agility and innovativeness, through maximizing firm’s competitive advantage, firms should continually adapt to the fast changing business environment and search for creative ways to satisfy new market needs.

Originality/value
Given the attention paid to supply chain agility and innovativeness in terms of importance to responding to business uncertainty and competitiveness, and more recently, as important capabilities in managing supply chain management, this paper investigates how IT integration and trust can contribute to supply chain agility and innovativeness. Provide evidence regarding the impact of IT integration and trust on agility of supply chains, innovativeness and competitive advantage.
Information asymmetry and equity issue decision of low-leverage firms
Authors: Sony Bipin , Bhaduri Saumitra 
Published: November 2018

PurposeThe purpose of this paper is to investigate the role of information asymmetry in the equity issue decision of two categories of Indian firms with distinct levels of information asymmetry – levered firms and unlevered firms.Design/methodology/approachThis paper proposes a novel empirical approach to compare these two categories of firms. Levered firms exposed to the debt markets are under the scrutiny of lenders, reducing their information asymmetry problems. On the other hand, unlevered firms, which are smaller firms with fewer tangible assets and no credit history suffers more information problems. The authors use a propensity score matching method to identify firms that share similar firm-specific characteristics in these groups and compare equity issues to analyze the impact of information asymmetry.FindingsThe results show that information asymmetry plays a key role in the equity issue decision of Indian firms. Additionally, the authors find that the trends and characteristics of low-leverage (LL) firms in India are comparable to the LL from developed economies, which is consistent with the findings that they face more information problems.Originality/valueUnlike the conventional approach of using proxy variables to capture information asymmetry, this study uses a novel framework where the authors compare the equity issue decision of similar firms in two categories with different degrees of information asymmetry.
Stakeholder input into the implementation of a new music therapy program in a mental health service
Authors: Bibb Jennifer , Castle David , McFerran Katrina Skewes 
Published: November 2018

Purpose
Music therapy programs are increasingly common and necessary in mental health services. However, there is little knowledge of the key factors which influence the successful implementation of new therapeutic programs. The purpose of this paper is to explore how stakeholder input influenced the implementation and sustainability of a new music therapy program in four services within a large government funded mental health department in Melbourne, Australia.

Design/methodology/approach
For a period of 12 months, two cycles of assessment, action and evaluation were conducted where data were collected through interviews with staff members, feedback from consumers and attendance in sessions.

Findings
A number of influential factors were identified as important in the successful implementation and future sustainability of the music therapy program. These included: the degree of staff support received; how the program was structured and facilitated; promotion of the program within the service; evaluation of the program; and congruence with the existing therapeutic program.

Research limitations/implications
Results suggest that successful implementation and future sustainability of a music therapy program is dependent on the flexibility of the program to the context and culture of the existing setting.

Originality/value
This is the first study to incorporate contributions from stakeholders in the implementation of a new music therapy program in a mental health service.
Test for volatility spillover effects in Japan’s oil futures markets by a realized variance approach
Authors: Nakajima Tadahiro 
Published: November 2018

Purpose
The purpose of this paper is twofold. First, the paper examines the risk transmission between crude oil and petroleum product prices of Japan’s oil futures market. Second, it compares the performance of two tests for Granger causality using realized variance (RV) and the exponential generalized autoregressive conditional heteroscedasticity (EGARCH) model.

Design/methodology/approach
The author measures the daily RV of crude oil, kerosene and gasoline futures listed on the Tokyo Commodity Exchange using high-frequency data, and he examines the Granger causality in variance between these variables using the vector autoregression model. Further, the author estimates the EGARCH model based on daily data and test for Granger causality in variance between commodity futures using Hong’s (2001) approach.

Findings
The results of the RV approach reveal that the hypothesis on the existence of a mutual volatility spillover between crude oil and petroleum product markets is accepted. However, the results of the conventional approach indicate that all the hypotheses on Granger causalities in variance are rejected. The methodology based on intraday high-frequency data exhibits higher power than the conventional approach based on daily data.

Originality/value
This is the first paper to investigate Japan’s oil market using RV. The authors conclude that the approach based on RV is universally adoptable when testing for Granger causality in variance.

Authors: Smith Jodie , Levickis Penny , Eadie Tricia , Bretherton Lesley , Conway Laura , Goldfeld Sharon 
Published: November 2018

AbstractBackgroundVariations in parenting, more specifically less responsive and more directive parenting, contribute to language difficulties for children experiencing adversity. Further investigation of associations between specific responsive and directive behaviours and child language is required to understand how behaviours shape language over time within different populations. As language is dyadic, further exploration of how mother–child interactions moderate associations is also important.AimsTo investigate associations between specific responsive and directive maternal behaviours, the quality of mother–child interaction (fluency and connectedness) and child language in a cohort experiencing adversity.Methods & ProceduresPregnant women experiencing adversity were recruited from maternity hospitals in Australia. At 12 months, videos of mother–infant free play were collected. Videos were coded for maternal behaviours and fluency and connectedness (n = 249). At 36 months, child language was measured using a standardized language test. Linear regression models were used to examine associations and the moderating role of fluency and connectedness was explored.Outcomes & ResultsResponsive yes/no questions were positively associated with language scores. Unsuccessful redirectives were negatively associated with language scores. The moderation effect of fluency and connectedness was equivocal in the current data.Conclusions & ImplicationsFindings reproduce and extend previous research highlighting key features of mother–child interactions associated with child language trajectories. Findings also augment knowledge of risk and protective factors related to language for children experiencing adversity and highlight where targeted interventions might be successful.

AbstractBackgroundDetecting asymptomatic and undiagnosed atrial fibrillation (AF) is increasingly important. Recently, we developed a wristwatch‐based pulse wave monitor (PWM; Seiko Epson, Japan) capable of long‐term recording, with an automatic diagnosis algorithm that uses frequency‐based pulse wave analysis. The aim of this study was to evaluate the validity of continuous pulse wave monitoring for detection of AF.MethodsDuring the electrophysiological study (EPS) in patients with AF, simultaneous pulse wave monitoring and Holter electrocardiograms (ECG) were recorded (n = 136, mean age 62.7 ± 10.9 years). The diagnostic accuracy of the PWM for AF was compared to the Holter ECG diagnosis. Standard performance metrics (sensitivity [Se], specificity [Sp], positive predictive value [PPV], and negative predictive value [NPV]) were calculated. The duration‐based measurements were based on the diagnosis concordance ratios for the duration of time between diagnosis detected by the PWM and true diagnosis by the Holter ECG (AF or not AF). The episode‐based performance metrics were based on the proportion of episodes appropriately detected with the PWM relative to episodes determined by the Holter ECG.ResultsThe total recording time was 1,542,770 s (AF: 270,945 s). A high diagnostic Sp (patient average: 96.4%, cumulative: 97.7%) and NPV (patient average: 95.1%, cumulative: 96.8%) were obtained in the duration‐based results. In the episode‐based metrics, all indices significantly improved with longer AF episode durations.ConclusionsContinuous pulse wave monitoring can provide accurate and dependable information to aid in AF diagnosis. A high validity in confirming freedom from AF was shown by a high NPV.

Published: November 2018

ObjectiveTo evaluate the prevalence of penile curvature and health‐seeking behaviour in Australian men.Patients and MethodsA population‐based, cross‐sectional anonymous web‐based survey was designed, and men aged between 35 and 75 years in major and rural metropolitan cities across Australia were invited to participate. Respondents were screened for self‐reported symptoms of penile curvature and their impact on various psychosexual domains.ResultsOf a total of 1782 men who responded, 333 men (19%) reported a bend or curve in their penis and completed the main section of the questionnaire to address the impact of penile curvature on various psychosexual domains. A third of men with penile curvature (32%) reported penile curvature of ≥ 30°, with approximately equal proportions among the three age groups (33% in those aged 35–49 years, 37% in those aged 50–64 years, and 30% in those aged 65–75 years) and with no significant difference detected in the penile curvature characteristics between men in major metropolitan and those in rural cities across Australia. One in six men reported an adverse impact of penile curvature in their lives, complaining of penile pain or discomfort when they had an erection, while 26% of men were bothered by the appearance of their penis and 20% were bothered when they tried to have sexual intercourse. Men aged 35–49 years were more likely than those aged 65–75 years to be bothered by the penile curvature (31% vs 18%; P < 0.05) and men in the age group 65–75 years were twice as likely to have trouble with sexual intercourse compared with other age groups (39% vs 18%; P < 0.05).ConclusionsThis first population‐based study to estimate the prevalence of penile curvature in Australia highlighted that penile curvature is common and has a significant adverse impact on psychosexual functions.

Molecular mechanisms involved in the relapse of T‐cell acute lymphoblastic leukemia (T‐ALL) are not fully understood, although activating NOTCH1 signaling due to NOTCH1/FBXW7 alterations is a major oncogenic driver. To unravel the relevance of NOTCH1/FBXW7 mutations associated with relapse, we performed whole–exome sequencing in 30 pediatric T‐ALL cases, among which 11 diagnosis‐relapse paired cases were further investigated to track the clonal evolution of relapse using amplicon–based deep sequencing. NOTCH1/FBXW7 alterations were detected in 73.3% (diagnosis) and 72.7% (relapse) of cases. Single nucleotide variations in the heterodimerization domain were the most frequent (40.0%) at diagnosis, whereas proline, glutamic acid, serine, threonine–rich (PEST) domain alterations were the most frequent at relapse (54.5%). Comparison between non–relapsed and relapsed cases at diagnosis showed a predominance of PEST alterations in relapsed cases (P = .045), although we failed to validate this in the TARGET cohort. Based on the clonal analysis of diagnosis‐relapse samples, we identified NOTCH1 “switching” characterized by different NOTCH1 mutations in a major clone between diagnosis and relapse samples in 2 out of 11 diagnosis‐relapse paired cases analyzed. We found another NOTCH1 “switching” case in a previously reported Berlin‐Frankfurt‐Münster cohort (n = 13), indicating NOTCH1 importance in both the development and progression of T‐ALL. Despite the limitations of having a small sample size and a non–minimal residual disease–based protocol, our results suggest that the presence of NOTCH1 mutations might contribute to the disease relapse of T‐ALL.

Published: November 2018

SummaryObjectivePost‐thyroidectomy hypocalcaemia is a significant cause of morbidity and prolonged hospitalization, usually due to transient parathyroid gland damage, treated with calcium and vitamin D supplementation. We present a randomized, double‐blinded placebo‐controlled trial of preoperative loading with high‐dose cholecalciferol (300 000 IU) to reduce post‐thyroidectomy hypocalcaemia.Patients and MeasurementsPatients (n = 160) presenting for thyroidectomy at tertiary hospitals were randomized 1:1 to cholecalciferol (300 000 IU) or placebo 7 days prior to thyroidectomy. Ten patients withdrew prior to surgery. The primary outcome was post‐operative hypocalcaemia (corrected calcium <2.1 mmol/L in first 180 days).ResultsThe study included 150 patients undergoing thyroidectomy for Graves’ disease (31%), malignancy (20%) and goitre (49%). Mean pre‐enrolment vitamin D was 72 ± 26 nmol/L. Postoperative hypocalcaemia occurred in 21/72 (29%) assigned to cholecalciferol and 30/78 (38%) participants assigned to placebo (P = 0.23). There were no differences in secondary end‐points between groups. In pre‐specified stratification, baseline vitamin D status did not predict hypocalcaemia, although most individuals were vitamin D replete at baseline. Post‐hoc stratification by day 1 parathyroid hormone (PTH) (<10 pg/mL, low vs ≥10 pg/mL, normal) was explored due to highly divergent rates of hypocalcaemia in these groups. Using a Cox regression model, the hazard ratio for hypocalcaemia in the cholecalciferol group was 0.56 (95%CI 0.32‐0.98, P = 0.04) after stratification for Day 1 PTH. Further clinical benefits were observed in these subgroups.ConclusionsPre‐thyroidectomy treatment with high‐dose cholecalciferol did not reduce the overall rate of hypocalcaemia following thyroidectomy. In subgroups stratified by day 1 PTH status, improved clinical outcomes were noted.

Published: November 2018

AbstractObjectiveTo test the accuracy of measurement of interproximal peri‐implant bone defects at titanium (Ti) and zirconium dioxide (ZrO2) implants by digital periapical radiography (PR) and cone beam computed tomography (CBCT).Material and methodsA total of 18 models, each containing one Ti and one ZrO2 implant, were cast in dental stone. Six models each were allocated to following defect groups: A—no peri‐implant defect, B—1 mm width defect, C—1.5 mm width defect. The defect width was measured with a digital sliding caliper. Subsequently, the models were scanned by means of PR and CBCT. Three examiners assessed the defect width on PR and CBCT. Wilcoxon signed‐rank test and Wilcoxon rank sum test were applied to detect differences between imaging techniques and implant types.ResultsFor PR, the deviation of the defect width measurement (mm) for groups A, B, and C amounted to 0.01 ± 0.03, −0.02 ± 0.06, and −0.00 ± 0.04 at Ti and 0.05 ± 0.02, 0.01 ± 0.03, and 0.09 ± 0.03 at ZrO2 implants. The corresponding values (mm) for CBCT reached 0.10 ± 0.11, 0.26 ± 0.05, and 0.24 ± 0.08 at Ti and 1.07 ± 0.06, 0.64 ± 0.37, and 0.54 ± 0.17 at ZrO2 implants. Except for Ti with defect A, measurements in PR were significantly more accurate in comparison to CBCT (p ≤ 0.05). Both methods generally yielded more accurate measurements for Ti than for ZrO2.ConclusionsThe assessment of interproximal peri‐implant defect width at Ti and ZrO2 implants was more accurate in PR in comparison to CBCT. Measurements in CBCT always led to an overestimation of the defect width, reaching clinical relevance for ZrO2 implants.
