Relations outside the workplace matter! A nexus of coworker ostracism, relational capital, alternate belongingness and knowledge hiding
Authors: Fatima Tehreem , Bilal Ahmad Raza , Imran Muhammad Kashif , Waqas Muhammad 
Published: May 2022

PurposeThe current study aims to investigate the impact of coworker ostracism on coworker-directed knowledge hiding through the mediating role of relational social capital and moderating role of alternate belongingness in Pakistani higher educational settings.Design/methodology/approachA time-lagged study was carried out in which data from teaching and non-teaching faculty (N= 217) from the higher education sector of Lahore, Pakistan, were collected through multi-stage sampling. The collected data were analysed using moderated mediation analysis (PROCESS model 4 and 7).FindingsThe results revealed that ostracism from coworkers has an unfavourable impact on relational social capital that in turn promotes knowledge hiding. Nonetheless, if ostracized employees had sources to fulfil belongingness needs outside the work settings, this negative association was strengthened.Originality/valueThe authors have taken the role of belongingness outside the workplace in explaining the coworker ostracism and knowledge hiding relationship in higher educational settings and identified the explanatory role of relational social capital.
Supply chains and the success of M&As: investigating the effect of structural equivalence of merging firms' supplier and customer bases
Authors: Chae Sangho , Son Byung-Gak , Yan Tingting , Yang Yang S. 
Published: May 2022

PurposeThis study investigates the extent to which structural equivalence between acquiring and target firms is associated with post-merger and acquisition (M&A) performance—a relationship that is proposed to be moderated by industry-level vertical relatedness between acquiring and target firms.Design/methodology/approachApplying social network analysis and regression, this study analyzes a buyer–supplier relationship network dataset of 279 M&A deals completed between 2010 and 2017 to test the hypotheses. Structural equivalence is measured as the proportion of common customers and suppliers between an acquiring firm and a target firm.FindingsSupporting a view about the importance of supply chains in explaining M&As outcomes, the results suggest that the structural equivalence in the supplier network is positively associated with post-M&A firm performance. The results also show that the effect of the structural equivalence in the customer network is moderated by vertical relatedness between two merging firms (i.e. structural equivalence contributes to post-M&A performance when vertical industry relatedness is high).Originality/valueThis study contributes to the M&A and supply network literature by investigating the performance implications of structural equivalence in supplier and customer networks, demonstrating the importance of taking a supply chain view when explaining M&As outcomes. Specifically, the authors suggest considering structural equivalence as a new type of relatedness between merging firms (i.e. relatedness in network resources in explaining post-M&A performance). It also indicates how industry-level vertical resource relatedness, which is about relatedness in internal resources between the two firms, could interact with firm-level network resource relatedness, which is about relatedness in external supply chain resources between the two firms, in affecting post-M&A performance.
Guidelines for public sector managers on assessing the impact of outsourcing on business continuity strategies: a Brazilian case
Authors: Aragão João Paulo Santos , Fontana Marcele Elisa 
Published: May 2022

Purpose
This paper aims to propose guidelines for public sector managers in assessing the impact of outsourcing on business continuity (BC) strategies. This paper evaluated how public managers from the state of Pernambuco, Brazil, perceive outsourcing, considering BC and how it relates to the outsourcing of services and activities.

Design/methodology/approach
Theoretical lenses of outsourcing and BC were used to derive the study hypotheses. A questionnaire was drawn up to collect information to test the hypotheses. To test the proposed hypotheses, binary logistic regression was used through an empirical analysis of a sample of 51 Brazilian public managers.

Findings
This study found that when the public sector suffers from negative impacts of financial restrictions, outsourced services are the first ones to receive the negative impacts. This has had an adverse impact on BC in the public sphere. On the other hand, the authors verified that the public sphere’s capacity for resilience and the existence of specific methodologies to support public managers in outsourcing decision-making can contribute to BC.

Research limitations/implications
This study assists public organizations to take advantage of internal outsourced services in the best possible way, making better use of public resources, gaining social legitimacy and legitimacy also in the provision of public services. However, each public sector can present different risks of non-continuity, and this aspect could not be considered in this research as well.

Originality/value
This study is a pioneer in highlighting the relationships between outsourcing strategies and BC in public services in Brazil. Through the guidelines discussed in this study, public managers could develop a more effective response to the implications of post-outsourcing budget constraints. In addition, the findings of this paper add to an understanding of the importance of business strategies for public services continuity and seek to help reduce uncertainties and better inform the government decision-making process.
The mediating effects of psychological states on the relationship of job dimensions to personal and work outcomes, for fresh graduates
Authors: Serhan Carole , Tsangari Haritini 
Published: May 2022

PurposeIn today's challenging markets, organizations need to explore new ways to maximize employees' effectiveness and job satisfaction. Within this context, employed fresh graduates are a special group, which requires attention. Recognizing its needs in job design is one of the keys. The aim of the study is to determine the mediating role of experienced psychological states in the relationship between job dimensions and personal/work outcomes (motivation, satisfaction, effectiveness and commitment).Design/methodology/approachThe new “modified job characteristics model” (MJCM) was implemented, where the focus was on testing if experienced psychological states play a mediating role. An index for summarizing core job dimensions (modified motivating potential score (MMPS)) was also developed in the study. For the empirical testing of the new modeling framework, a sample of 630 employed fresh graduates in Lebanon was selected. Various statistical analyses were performed, including partial correlation and multiple regression analysis.FindingsResults showed that for those core job dimensions that significantly affected fresh graduates' personal/work outcomes, the relation was not direct causal, but was mediated by “experienced meaningfulness of the work”, “experienced responsibility for outcomes of the work”, “knowledge of results”, “self-confidence” and “prestige inside outside”. Further, MMPS was verified as a valid score reflecting the “motivating potential” of a job.Practical implicationsThe findings demonstrate the importance of effectively designing and redesigning jobs: employers should focus on the core job dimensions and adopt an adjusted strategy to enhance fresh graduates' affective and behavioral responses.Originality/valueThe current study innovatively examines fresh graduates' psychological states and their role as a mediator in the relation between job dimensions and job satisfaction or commitment. A new modeling framework is used and an index for summarizing job dimensions is developed.
Residual stresses in additively manufactured parts: predictive simulation and experimental verification
Authors: Shaikh Mohammad Qasim , Berfield Thomas A. , Atre Sundar V. 
Published: May 2022

Purpose
The purpose of this paper is to investigate a simulation solution for estimating the residual stresses developed in metal fused filament fabrication (MF3) printed parts. Additionally, to verify these estimates, a coupled experimental–computational approach using the crack-compliance method was investigated in this study.

Design/methodology/approach
In this study, a previously validated thermomechanical process simulation was used to estimate the residual stresses developed in the MF3 printing process. Metal-filled polymer filament with a solids loading of 59 Vol.% Ti-6Al-4V was studied. For experimental validation of simulation predictions, the MF3 printed green parts were slitted incrementally and the corresponding strains were measured locally using strain gauges. The developed strain was modeled in finite-element-based structural simulations to estimate a compliance matrix that was combined with strain gauge measurements to calculate the residual stresses. Finally, the simulation results were compared with the experimental findings.

Findings
The simulation predictions were corroborated by the experimental results. Both results showed the same distribution pattern, that is, tensile stresses at the outer zone and compressive stresses in the interior. In the experiments, the residual stresses varied between 1.02 MPa (tension) and −2.28 MPa (compression), whereas the simulations were predicted between 1.37 MPa (tension) and −1.39 MPa (compression). Overall, there was a good quantitative agreement between the process simulation predictions and the experimental measurements, although there were some discrepancies. It was concluded that the thermomechanical process simulation was able to predict the residual stresses developed in MF3 printed parts. This validation enables the printing process simulation to be used for optimizing the part design and printing parameters to minimize the residual stresses.

Originality/value
The applicability of thermomechanical process simulation to predict residual stresses in MF3 printing is demonstrated. Additionally, a coupled experimental–computational approach using the crack-compliance method was used to experimentally determine residual stresses in the three-dimensional printed part to validate the simulation predictions. Moreover, this paper presents a methodology that can be used to predict and measure residual stresses in other additive manufacturing processes, in general, though MF3 was used as demonstrator in this work.

Authors: Singh Navjit , Arora Simran , Kapur Bharti 
Published: May 2022

Purpose
The purpose of this paper is to examine current trends in over the top (OTT) research through bibliometric analysis of Scopus and Web of Science indexed publications. This study attempted to identify the thrust areas that may be addressed through future research initiatives.

Design/methodology/approach
This study included bibliometric analysis of research articles published on OTT domain for a time period ranging from 2011 to 2021. The authors were able to extract 137 unique articles from selected databases with inclusion criteria limited to social sciences only. The retrieved data is then analyzed using the R studio and VoSviewer user interfaces. Finally, discussions on citations, keywords, authors and source contributions toward the development of field were presented using descriptive and visual displays.

Findings
OTT as a research theme has gained wider acceptance recently. However, there is a scarcity of studies on the subject. The authors discovered that previous studies in the field had focused on technological aspects of the domain thus leaving a plethora of opportunities for future researchers to explore. In this regard, the findings enlisted few unexplored domains specific to OTT that require immediate attention of the researchers and stakeholders. It was suggested to investigate the field from marketing, behavioral, regulatory, social and quality aspects so as to broaden its scope.

Originality/value
To the best of the authors’ knowledge, this is going to be the first bibliometric study ever conducted on OTT research. This study may be considered unique in identifying current trends in OTT research and recommending a course of action for future researchers.

AbstractObjectiveTo test the hypothesis that potential missed opportunities for antenatal corticosteroids increase as gestational age decreases and are associated with adverse outcomes.DesignObservational cohort study.SettingTwenty‐four US centers in the Neonatal Research Network.PopulationActively treated infants at 22–25 weeks of gestation and with birthweight 401–1000 g, without major birth defects, born 2006–18.MethodsPotential missed opportunity was defined as no antenatal corticosteroids but did have prenatal antibiotics, and/or magnesium sulphate, and/or prolonged rupture of membranes. Poisson regression models adjusted for baseline characteristics.Main outcome measuresAntenatal corticosteroid exposure, mortality and severe intracranial haemorrhage or periventricular leucomalacia.ResultsA total of 6966 (87.5%) infants were exposed to antenatal corticosteroids, 454 (5.7%) had no exposure but potential missed opportunities for antenatal corticosteroid exposure, and 537 (6.7%) had no exposure and no evidence of potential missed opportunities. Compared with infants born at 25 weeks, potential missed opportunities for antenatal corticosteroid exposure were more likely at 22 weeks (adjusted relative risk [aRR] 11.06, 95% confidence interval [CI] 7.52–16.27) and 23 weeks (aRR 3.24, 95% CI 2.44–4.29) but did not differ at 24 weeks (aRR 1.08, 95% CI 0.82–1.42). Potential missed opportunities for antenatal corticosteroids decreased over time at 22–23 weeks of gestation. Antenatal‐corticosteroid‐exposed infants had lower risk of death (31.0% versus 54.8%; aRR 0.77, 95% CI 0.70–0.84) and survivors had lower risk of severe brain injury (25.0% versus 44.5%; aRR 0.64, 95% CI 0.55–0.73) compared with infants with potential missed opportunities.ConclusionPotential missed opportunities for antenatal corticosteroid exposure increased with decreasing gestational age and were associated with higher rates of death and severe brain injury among actively treated periviable births.
Sengstaken–Blakemore tube in critical upper gastrointestinal bleeding: Implications for aeromedical retrieval
Authors: Latona Akmez , Chao Che‐Yung , Bartholdy Roland , Jarvis Christopher 
Published: May 2022

AbstractSengstaken–Blakemore tubes (SBTs) are rarely used in Australia, because of improved access to endoscopy and interventional radiology, as well as overall lower rate of variceal haemorrhage from improvements in primary prophylaxis. SBT's use is associated with significant rate of serious complications, such as oesophageal perforation, mucosal necrosis, aspiration pneumonia and respiratory compromise secondary to external compression of the trachea. As such, SBT is currently only recommended for use in life‐threatening variceal haemorrhage, where endoscopic, embolization and pharmacologic therapy have been unsuccessful or are unavailable. No data exist for its use in Australasia but one area that it could be indicated is for hemodynamically unstable patients in remote setting, where long transfer times often means delayed access to endoscopy. We present a case of SBT insertion in retrieval medicine and discuss placement in the management of an unstable upper gastrointestinal bleed, complicating factors such as lack of radiology to confirm balloon position, the impact of flight altitude on balloon pressures, the maintenance of traction in flight and logistics of long flight times across the state of Queensland. This is the first case report of SBT use in the Australian aeromedical environment. It is also the first one where SBT has been used for duodenal bleeding, although the source of bleeding was unknown prior to insertion.

AbstractBackgroundRecent studies indicated that T cell immunoreceptor with immunoglobulin and ITIM domains (TIGIT) and cluster of differentiation 47 (CD47) have emerged as new potential immunotherapy targets. However, the roles of TIGIT and CD47 in lung squamous cell carcinoma (LUSC) have not been fully illustrated.MethodsThe specimens and clinicopathological information from 190 LUSC patients who underwent surgeries in our center were retrospectively collected. Immunohistochemical staining for TIGIT and CD47 was conducted. Transcriptional and clinical data of 479 LUSC were downloaded from The Cancer Genome Atlas (TCGA).ResultsIn the TCGA LUSC cohort, 142 (29.6%) cases were TIGIT/CD47 dual high expression at RNA level. The expression levels of TIGIT and CD47 were significantly correlated (p < 0.001). The proportions of patients with high TIGIT expression (p = 0.001) and high TIGIT/CD47 dual high expression (p = 0.049) were both higher in female cases. Advanced TNM stage (p = 0.006) and TIGIT/CD47 dual high expression (p = 0.047) were independent prognostic factors for LUSC. In the 190 LUSC cohort of our center, 75 (39.5%) cases were TIGIT/CD47 dual high expression at protein level. Cross‐table analysis showed a correlation between TIGIT and CD47 expression. Older age (p = 0.001), advanced TNM stage (p < 0.001) and TIGIT/CD47 dual high expression (p = 0.046) were independent prognostic factors in our cohort.ConclusionWe found that TIGIT and CD47 dual high expression was associated with poor prognosis in LUSC. We speculated that patients with dual high expression of CD47/TIGIT might be suitable for new target immunotherapy in the future.

AbstractFor the first time in Russia, instrumental neutron activation analysis (INAA) and related analytical techniques were used to determine the distribution patterns of elemental composition in archeological pottery in terms of classification and provenance of medieval pottery. A total of 48 fragments have been discovered in three locations; Bolgar, the Moscow Kremlin (MosKremlin), and Selitrennoe settlement (Selitrennoe). The assemblages were subjected to INAA in order to determine the concentrations of 37 elements in mg/kg. The data were analyzed using geochemical, bivariate, and multivariate statistical techniques. To classify the fragments according to their origin hierarchical clustering (HCA), linear discriminant (LDA), and principal component analyses (PCA) were used. Based on the INAA results, the first attempt was made to apply machine learning methods to the study of artifacts in Russia. The results show that they are reliable and powerful in extracting information about critical elements for identifying ceramic fragments and using them as chemical fingerprints. Chromium was the most useful element and was used in conjunction with other elements as a fingerprint to distinguish sherds. Chemical and statistical analyses help to establish of reference groups for medieval archeological pottery, which will be used in the future to classify and identify various unknown sherds. These reference groups serve as baseline data for determining the fragment's place of manufacture and are considered a reasonable judgment based on experimental data.

AbstractLaparoscopic choledochal cyst excision and hepaticojejunostomy is a representative surgical procedure requiring laparoscopic suturing including needle driving and knot tying. Laparoscopic needle driving and knot tying is a highly technically demanding skill, especially in small infants and children. We developed a laparoscopic hepaticojejunostomy simulator for training. This simulator was developed for a 1‐year‐old infant body size based on computed tomography data and reproduced a pneumoperitoneum condition based on 3D scanner data of the clinical situation. Surgeon in training (SITs) of our institution have to acquire practice of laparoscopic hepaticojejunostomy using a simulator before performing clinical cases. Thirteen cases of choledochal cyst have been managed at our institution since the introduction of practice using this simulator in 2016. Six SITs performed 13 cases of laparoscopic choledochal cyst excision and hepaticojejunostomy. There were no cases of anastomotic bile leakage. Laparoscopic disease‐specific simulator practice is effective for the acquisition of secure hepaticojejunostomy skills for the treatment of choledochal cysts in children as off‐the‐job training.

AbstractStudy 309/KEYNOTE‐775 is a phase 3 open‐label, randomized trial of lenvatinib plus pembrolizumab versus treatment of physician's choice (TPC) in patients with advanced endometrial cancer with progression after platinum‐based therapy. Primary endpoints of superiority for lenvatinib plus pembrolizumab were met for progression‐free survival (PFS) and overall survival (OS) in all‐comers (ie, regardless of mismatch repair [MMR] status) and patients with MMR proficiency (pMMR). We present results for the Japanese subset. Patients were randomized to oral lenvatinib 20 mg/day plus intravenous pembrolizumab 200 mg every 3 weeks (Q3W; up to 35 cycles of pembrolizumab) or TPC (intravenous doxorubicin 60 mg/m2 Q3W or paclitaxel 80 mg/m2 QW [3 weeks on/1 week off]). Primary endpoints were PFS by blinded independent central review per RECIST version 1.1 and OS. One hundred four patients were randomized in Japan (data cutoff, October 26, 2020; median follow‐up, 11.8 [range, 1.1–26.9] months). Hazard ratios (HRs) for PFS with lenvatinib plus pembrolizumab versus TPC were 1.04 (95% CI, 0.63–1.73) in patients with pMMR and 0.81 (0.50–1.31) in all‐comers. Hazard ratios for OS were 0.74 (0.41–1.34) with pMMR and 0.59 (0.33–1.04) for all‐comers. Adverse events were manageable and led to discontinuation of one/both study drugs in 36.5% of patients in the lenvatinib plus pembrolizumab group versus 7.8% in the TPC group. Similar to the global Study 309/KEYNOTE‐775 results, this analysis suggested favorable efficacy and manageable safety with lenvatinib plus pembrolizumab after platinum‐based chemotherapy in Japanese patients with advanced endometrial cancer and supports this combination as a new standard of care in this population.
