Social networks and family firm internationalisation: cases from a transition economy
Authors: Kryeziu Liridon , Coşkun Recai , Krasniqi Besnik 
Published: July 2021

PurposeThe purpose of this study is to examine the impact of family firms’ types of social networks on internationalisation. By investigating the mechanisms and the process and complexity regarding the operation, function and impact of social networks, this paper aims to gain insights and understand the dynamism concerning the content, and process as well as build rich and detailed construct analysis.Design/methodology/approachThis study used a qualitative case study as a research strategy to examine the impact of social networks on family firm internationalisation. A qualitative research strategy was used as the impact of networking relations and structure is challenging to be measured statistically.FindingsThe findings suggest that family firm internationalisation was gradual and characterised by an incremental learning process. This process facilitated the networking relations and structures that helped firms improve their quality, product diversification and set competitive prices.Research limitations/implicationsThis study’s first limitation is that it focused mainly on low technology manufacturing firms. This paper recommends examining how high technology firms maximise social networks. Secondly, this paper examined family firms; therefore, this paper recommends comparing and contrasting networking relations and family and nonfamily firms' social structure. Thirdly, being limited only to social networks, this study did not focus on the impact of ownership; this paper suggests future studies to examine family ownership and involvement in firm internationalisation.Originality/valueUnderstanding how firms’ social network types influence family firms’ internationalisation in a transition economy is critical to ensuring family businesses’ expansion. This study explains how family firms use social networks to internationalise, extending the current understanding of family business literature in transition economies. It also provides implications for policymakers and family firms managers for improving the growth prospects of family businesses.
Analysis of factors influencing energy consumption of material extrusion-based additive manufacturing using interpretive structural modelling
Authors: P. Ramesh , S. Vinodh 
Published: July 2021

Purpose
Material extrusion (MEX) is a class of additive manufacturing (AM) process based on MEX principle. In the viewpoint of Industry 4.0 and sustainable manufacturing, AM technologies are gaining importance than conventional manufacturing route (subtractive manufacturing). Because of the ease of use and lesser operation skills, MEX had wide popularity in industry for product and prototype development. This study aims to analyze energy consumption of MEX-based AM process and its influencing factors.

Design/methodology/approach
A group of factors were identified pertaining to MEX-based AM process. In this viewpoint, this study presents the configuration of a structural model using interpretive structural modeling (ISM) to depict dominant factors in MEX-based AM process. A total of 18 influencing factors are identified and ranked using ISM methodology for MEX process. The Impact Matrix Cross-reference Multiplication Applied to a Classification analysis was done to categorize influencing factors into four groups for MEX-based AM process.

Findings
The derivation of structural model would enable AM practitioners to systematically analyze the factors and to derive key factors which enable comprehensive energy modeling and energy assessment studies. Also, it facilitates the development of energy efficient AM system.

Originality/value
The development of structural model for analysis of factors influencing energy consumption of MEX-based AM is the original contribution of the authors.

Authors: Magana Carranza Rodrigo , Robinson Joseph , Ashton Ian , Fox Peter , Sutcliffe Christopher , Patterson Eann 
Published: July 2021

Purpose
The purpose of this paper is to detail the design and first use of a force transducer device to study the development of forces during the laser-powder bed fusion (L-PBF) process from which residual stresses can be inferred.

Design/methodology/approach
The proposed novel device consists of an array of load cells for in-situ measurement of forces over time during the L-PBF additive manufacturing process. Measurements of the developed forces layer by layer were recorded in a first build using a 67-degree rotating scan strategy using Inconel 625 build material.

Findings
Preliminary experimental results from in-situ measurements using a 67-degree rotating scan strategy showed that the forces induced in the first five layers represented approximately 80% of the maximum on completion of the build and were distributed such as to induce concave deformation of the part, i.e. tension in the centre and compression at the edges of the part.

Originality/value
This paper describes a novel device for in-process measurement of the spatial distribution and time-varying nature of the forces induced during the L-PBF process as well as an evaluation of the residual forces following the completion of the build.
Effects of the COVID-19 pandemic on stock market returns and volatilities: evidence from selected emerging economies
Authors: Rakshit Bijoy , Neog Yadawananda 
Published: July 2021

Purpose
The purpose of this paper is to investigate the effects of exchange rate volatility, oil price return and COVID-19 cases on the stock market returns and volatility for selected emerging market economies. Additionally, this study compares the market performance in the emerging economies during the COVID-19 pandemic with the pre-COVID and global financial crisis (GFC) period.

Design/methodology/approach
The authors apply the arbitrage pricing theory to model the risk-return relationship between the risk-based factors (exchange rate volatility and COVID-19 cases) and stock market returns. By applying the exponential generalized autoregressive conditional heteroskedasticity model, the study captures the asymmetric volatility spillover from the stock markets to foreign exchange markets and vice versa.

Findings
Findings reveal that exchange rate volatility exerts a negative and significant effect on the market returns in Brazil (BOVESPA), Chile (S&P CLX IPSA), India (SENSEX), Mexico (S&P BMV IPC) and Russia (MOEX) during the coronavirus pandemic. Regarding the effect of oil price returns, the authors find a positive relationship between oil price and stock market returns across all the economies in the study. The market returns of Russia, India, Brazil and Peru appeared more volatile during the pandemic than the GFC period.

Practical implications
As the exchange rate volatility is causing higher risk and uncertainty in the stock market’s performance, the central bank’s effort to maintain a stabilizing effect on the exchange rate sale can be proven crucial for the economies under consideration. Emphasized should also be given to boost investors’ confidence in the stock market, and for this, the government policy actions in reducing the transmission of the disease are the need of the hour.

Originality/value
While a large volume of literature on stock market performance in times of COVID-19 has emerged from developed economies, this study adds to the literature by exploring the emerging economies’ stock market performance during the COVID-19 pandemic. Unlike previous literature, this study examines the volatility spillover between stock and exchange rate markets in the worst affected emerging economies during the crisis.
The United States Army Medical Command, becoming a learning organization
Authors: Hartstein Bonnie , Yackel Edward 
Published: July 2021

Purpose
This study aims to describe how the Army and the Army Medical Department matured as a learning organization (LO) during the period after the 2014 Military Health System Review through the incorporation of changes aimed at improving patient safety, data transparency and becoming a high-reliability organization (HRO). This study explores the relationship between HRO and LO concepts by adding to the body of knowledge in both disciplines.

Design/methodology/approach
Four large-scale system changes are presented and evaluated against the principles of the LO. Metric data were collected longitudinally and presented as submitted to several nationally-recognized organizations in healthcare quality and safety. Post initiative observations are paired with a corresponding LO principle to assess US Army Medical Command’s (MEDCOM’s) maturation as a LO. System changes/improvements and the advancement of LO principles are discussed.

Findings
System improvements, analyzed critically alongside paired LO principles, show strong correlation between high-reliability and LO principles. Despite inherent institutional barriers, this study demonstrates that, when leveraged effectively, the leadership hierarchy and command culture can accelerate transformation into an LO.

Originality/value
This study explores changes implemented in MEDCOM, as it evolved as a stronger LO. It demonstrates how healthcare organizations and other high-risk industries that embrace high-reliability concepts will become better LOs and expands current knowledge on how LO concepts in healthcare can affect better system accountability and improved patient safety. Organizations can learn from MEDCOM’s journey changes that can hasten progress toward adoption of LO principles, especially in hierarchical organizations.

Published: July 2021

Purpose
Inefficient waste disposal technique and cement production methodology caused significant environmental impacts, leading to global warming. The purpose of the research was to invent an effective, sustainable technology to use the wastes and alternate for cement in concrete. Geopolymer technology could be the most desirable solution to use the wastes into an effective product.

Design/methodology/approach
The wood waste ash derived from nearby tea shops was used as an alternate binder for fly ash. The replacement of WWA with FA was varied from 0 to 100% at 10% intervals. In this research, setting and mechanical features of Geopolymer Concrete (GPC) along with Waste wood ash (WWA) was carried out. The influence of wood waste ash in the microstructure of the GPC was also assessed using scanning electron microscope and X-ray diffraction analysis.

Findings
The findings revealed that 30% replacement of wood waste ash was performed higher in all measured features. Besides, the formation of different phases was also observed with the inclusion of wood waste ash.

Research limitations/implications
The demand for fly ash was increased in recent years, and the fly-based GPC has required more alkaline solution and temperature curing. Hence, there was a research gap on finding an alternative binder for fly ash.

Originality/value
The research novelty was to use the wood waste ash, which has inbuilt alkaline compounds on the production of sustainable geopolymer. The finding showed that the wood waste ash could be alternate fly ash that eliminates the environmental impacts and economic thrust.
Processing trauma in psychoanalysis in ‘real’ time and in dreams: the convergence of past, present and future during COVID‐19
Authors: Bryon Deborah 
Published: July 2021

AbstractIn the current collective unrest, we and our analysands are living in real time and need vantage points from which to make meaning, as subjective experience of time is collapsing. For many analysands, the past is being relived in the present, with no imaginable future. During the time of COVID‐19, dreams are providing a valuable mechanism in working with atemporal emotional trauma, previously uncontextualized. Dream metaphor can provide a transitional space to move around in within the analytic framework. This paper explores a variety of dreams from individual analysands demonstrating different ways of conceptualizing personal and collective experience, bridging between the past, present, and future. Parallels between feeling states related to the current condition and unprocessed implicit memories from the past will be examined, as a vehicle for processing past trauma. Dreams expressing current states of dread for an unimaginable future, as well compensatory dreams showing a hopeful vision of the future will be considered.

Published: July 2021

AbstractBackgroundSodium glucose cotransporter 2 inhibitor (SGLT2i) has recently been suggested to reduce the risk of cardiovascular events. Left ventricular hypertrophy (LVH) is associated with cardiovascular events. Diabetic macroangiopathy is a crucial complication in patients with diabetes mellitus (DM). This study examined the effect of SGLT2i on LVH in patients with type 2 DM (T2DM).MethodsThe retrospective cohort study was conducted in consecutive outpatients with T2DM from 2010 to 2020. Left ventricular mass index (LVMI) was used as an indicator of LVH based on echocardiography. The minimum follow‐up period was 1 year. After propensity score‐matching for clinical profiles, patients who underwent annual echocardiography twice for a routine checkup and took SGLT2i were defined to the SGLT2i group, whereas patients without SGLT2 inhibitors were defined to the non‐SGLT2 group. SGLT2i was administered after baseline echocardiography followed by a second examination.ResultsLVMI levels in the SGLT2i group (n = 169) significantly decreased from baseline compared with those in the non‐SGLT2i group (n = 169), % changes in LVMI2.7(g/m2.7) in median (interquartile ranges [IQR]) were − 7.7 (−18.7, 2.5) vs −3.6 (−14.3, 5.8), respectively, P = 0.017). In a subgroup analysis, LVMI levels in the patients who had LVH in the SGLT2i group more significantly decreased than those without LVH, % changes in LVMI2.7(g/m2.7) in median (IQR) were −13.5 (−22.1, −2.4) vs −2.8 (−12.6, 9.8), respectively, P < 0.001).ConclusionsSGLT2i treatment was shown to improve LVH in patients with T2DM and may play a pivotal role in the future treatment of diabetic cardiovascular complications.

SummaryProgressive retinal atrophy (PRA), common autosomal recessive disorder affecting several dog breeds including Shih Tzu, is characterized by degeneration of photoreceptors leading to blindness. To identify PRA genetic variants, three affected and 15 unaffected Shih Tzu and 20 non‐Shih Tzu were recruited. Dogs underwent ophthalmologic examination and electroretinography, revealing hallmark retina pathological changes and an abnormal electroretinography in all affected dogs but not in unaffected dogs. WGS was performed. Non‐synonymous homozygous variants were searched in coding regions of genes involved in retinal diseases/development; the criterion was that variants should only be present in affected dogs and should be absent in both unaffected and 46 genomes of dogs (from an available evolutionary database). Only one out of the 109 identified variants is predicted to harbor a high‐impact consequence, a nonsense c.452A>C (p.L151X) in the JPH2 gene. The genotype of JPH2 variant in all 38 dogs was determined with Sanger sequencing. All three affected dogs, but none of the 35 unaffected, were homozygous for the nonsense variant. JPH2 has been previously found to be expressed in several excitable cells/tissues including retina photoreceptors. Hence, JPH2 is a candidate gene for PRA in Shih Tzu.

Published: July 2021

SummaryInfraclavicular and supraclavicular approaches are used for subclavian venous catheterisation. We hypothesised that the supraclavicular approach is non‐inferior to the infraclavicular approach in terms of safety during ultrasound‐guided right subclavian venous catheterisation. We randomly allocated 401 neurosurgical patients undergoing ultrasound‐guided right subclavian venous catheterisation into supraclavicular (n = 200) and infraclavicular (n = 201) groups. We assessed catheterisation‐related complications (primary outcome measure) including catheter misplacement and mechanical complications (arterial puncture, haematoma formation, pneumothorax and haemothorax). We also recorded catheterisation success rates and time required for venous puncture and catheterisation. The number (proportion) of patients with catheterisation‐related complications was six (3.0%) in the supraclavicular group and 27 (13.4%) in the infraclavicular group, mean difference (95%CI) −10.4% (−15.7 to −5.1%), p < 0.001, with a significant difference also seen for catheter misplacement. Except for a shorter time (median (IQR [range]) required for venous puncture in the supraclavicular group, being 9 (6–20 [2–138]) vs. 13 (8–20 [3–99]) s, the incidence of mechanical complications and other catheterisation characteristics were similar between the two groups. We recommend the supraclavicular approach for ultrasound‐guided right subclavian venous catheterisation.

Published: July 2021

AbstractPurposeMicrobiomes have immunoregulatory functions and may be involved in the pathophysiology of eye diseases. However, the effects of microbiomes on uveitic glaucoma (UG) and open‐angle glaucoma (OAG) have not been sufficiently investigated. This study analysed differences in eyelid and buccal microbiomes between UG and OAG using metagenomic technology.MethodsEyelid and buccal specimens were collected from 34 UG and 62 OAG patients. The taxonomic composition of the microbiome was determined via 16S rRNA gene sequencing, operational taxonomic unit analysis and diversity analysis. Differential gene expression analysis (DEG) and principal component analyses (PCoA) determined taxon differences between the microbiomes of the UG and OAG patients. Subgroup analysis according to age and baseline IOP was performed.ResultsThere was no significant difference in alpha‐diversity between the microbiomes of UG and OAG patients. Further, PCoA revealed no differences in eyelid microbiome between the UG and OAG groups, but significant differences were found in buccal microbiome between the groups, especially in a subgroup of OAG patients with normal IOP. DEG analysis of the eyelid microbiome revealed various taxa differences, including the enrichment of Rhodococcus in UG samples over OAG samples. Taxa such as Lactobacillus and Proteus were significantly depleted (q‐value = 9.98e−6 and q‐value = 1.38 × 10−4, respectively) in the buccal microbiome of UG patients, whereas Enterococcus was enriched (q‐value = 5.26e−5).ConclusionsThis study showed that the buccal microbiome in UG differs from that in OAG; reduced Lactobacillus was observed in UG. These results suggest that apart than OAG, microbiome composition may be a factor in the pathogenesis of UG.

Published: July 2021

AbstractAimVancomycin is frequently used in paediatric hospitals. Data suggest trough levels of 10–20 mg/L are needed to achieve bacterial killing. This study aimed to evaluate if commonly used dosing regimens are efficient in reaching these levels and if therapeutic drug monitoring (TDM) was appropriately used.MethodsAll children receiving intravenous vancomycin at the Children´s Hospital Iceland between 2012 and 2016 were included. Vancomycin trough levels were registered. Student t test, Wilcoxon test and regression models were used for statistical analysis.ResultsA total of 105 children received 163 vancomycin treatments (55/105 neonates). Average daily dose in neonates was 23.4 mg/kg/day and 38.4 mg/kg/day for older children. No TDM was done in 58 treatments (35.6%). First trough levels were <10mg/L in 52.4% and <15mg/L in 92% of cases. Therapeutic levels were less likely achieved in children with malignancy (11.8%) compared with others (36.8%, p = 0.09).ConclusionsIn more than half of the cases, trough drug levels were <10 mg/L and malignancy was associated with the lowest probability of reaching therapeutic levels. This study suggests that starting doses of vancomycin in children should be higher, especially in relation to malignant diseases and supports the importance of antibiotic stewardship to ensure optimal antibiotic use.
Suppression of MyoD induces spontaneous adipogenesis in skeletal muscle progenitor cell culture

Published: July 2021

AbstractThe degree of intramuscular adipose tissue accumulation is one of the factors affecting meat quality. Accumulation of adipocytes is also observed under the pathological condition of skeletal muscle such as muscular dystrophy and sarcopenia. The origin of adipocytes seen in skeletal muscle is mesenchymal progenitor cells that can give rise to both adipocytes and fibroblasts. In the present study, we demonstrated that siRNA‐mediated suppression of MyoD expression in rat skeletal muscle progenitor cell culture, which comprises both myogenic satellite cells and mesenchymal progenitor cells, resulted in diminished myotube formation and an unexpected spontaneous appearance of white adipocytes. Suppressing myomaker expression also resulted in complete absence of myotube formation without reducing MyoD expression, but no adipogenesis was seen in this scenario, indicating that decline in MyoD expression rather than decreased myotube formation is necessary to induce adipogenesis. In addition, spontaneous adipogenesis induced by suppressing MyoD expression in culture was inhibited by the conditioned medium from control culture, indicating that anti‐adipogenic factor(s) are secreted from MyoD‐positive myogenic cells. These results indicate the presence of regulatory mechanism on adipogenesis by myogenic cells.

Published: July 2021

AbstractComplementing studies on youth mental health that were mainly depoliticised, this article offers a discursive examination of youth mental health in an Indonesian educational context. We argue that subject positions enabled by the discourse of mental health were at odds with dominant constructions of an ideal Indonesian citizen. Drawing upon qualitative data from 22 teachers and 20 students in a junior high school in Indonesia and analyses of educational policies and textbooks, we identified three discourses underpinning the ideal(ised) constructions of young Indonesian citizen, namely, neoliberalism, (masculine) patriotism and (religious) moralism and discussed how these inhibited youth mental health.
