Numerical study of heat transfer in high voltage solid insulating materials using transmission line method
Authors: Shamsi Amin , Ganjovi Alireza , Shayegani Akmal Amir Abbas 
Published: June 2022

Purpose
The purpose of this study is to numerically examine the heat transfer and transport of space charges in the solid insulating materials [low density polyethylene (LDPE), flame retardant type 4 (FR4), Polytetrafluoroethylene (PTFE)] using the transmission line modeling (TLM) method. Besides, a comprehensive study is performed on the mutual influences of heat transfer and space charges transport within the solid dielectric bulk.

Design/methodology/approach
The obtained governing equations including continuity and circuit equations are coupled with heat transfer equations, and they are solved via fourth-order Runge–Kutta method.

Findings
The electric potential and field, current density and temperature distribution are calculated. It is shown that compared with FR4 and PTFE, the temperature increment rate in LDPE is much lower. Moreover, the heat transfer in the solid insulating materials bulk increases the homo-charges density and temperature in the vicinity of electrodes. Hence, the reduction in electric field is reflected in the potential deformations in the proximity of electrodes. Furthermore, where the electric field is maximized, the temperature is minimized.

Research limitations/implications
This study is restricted to two-dimensional problems.

Originality/value
Interestingly, because of the lower temperature in LDPE, the current density and their increment rates in LDPE are much lower than that in FR4 and PTFE dielectric materials.
Market structure, institutional quality and bank stability: evidence from emerging and developing countries
Authors: Tran Hung Son , Nguyen Thanh Dat , Nguyen Thanh Liem 
Published: June 2022

Purpose
The purpose of this study is to carry out an empirical investigation about how the level of market concentration or competitiveness of the banking system and institutional quality are associated with bank’s financial stability.

Design/methodology/approach
This study uses dynamic panel data techniques on the sample of 133 developing and emerging countries over the years 2002–2020.

Findings
The authors document several significant findings. First, there is evidence that bank stability is positively associated with the level of market concentration. The result is in line with the concentration–stability view that banks operating in a more concentrated market tend to be more stable than those in a less concentrated market. Second, the results confirm that the quality of the institutional environment plays a critical role in improving the stability of banks in developing and emerging countries. Third, the authors find that institutional development can moderate the effect of market concentration (or competitiveness of the banking system) on bank stability. Specifically, the results show that better institutional quality enhances the positive influence of bank concentration on the bank’s financial stability in developing and emerging countries. These results are robust to different specifications with the alternative measures of bank stability and market concentration.

Originality/value
This study provides further understanding regarding the effects of the level of market concentration or competitiveness of the banking system and institutional quality on bank stability in 133 developing and emerging countries over the years 2002–2020.
A boosting-based transfer learning method to address absolute-rarity in skin lesion datasets and prevent weight-drift for melanoma detection
Authors: Singh Lokesh , Janghel Rekh Ram , Sahu Satya Prakash 
Published: June 2022

PurposeAutomated skin lesion analysis plays a vital role in early detection. Having relatively small-sized imbalanced skin lesion datasets impedes learning and dominates research in automated skin lesion analysis. The unavailability of adequate data poses difficulty in developing classification methods due to the skewed class distribution.Design/methodology/approachBoosting-based transfer learning (TL) paradigms like Transfer AdaBoost algorithm can compensate for such a lack of samples by taking advantage of auxiliary data. However, in such methods, beneficial source instances representing the target have a fast and stochastic weight convergence, which results in “weight-drift” that negates transfer. In this paper, a framework is designed utilizing the “Rare-Transfer” (RT), a boosting-based TL algorithm, that prevents “weight-drift” and simultaneously addresses absolute-rarity in skin lesion datasets. RT prevents the weights of source samples from quick convergence. It addresses absolute-rarity using an instance transfer approach incorporating the best-fit set of auxiliary examples, which improves balanced error minimization. It compensates for class unbalance and scarcity of training samples in absolute-rarity simultaneously for inducing balanced error optimization.FindingsPromising results are obtained utilizing the RT compared with state-of-the-art techniques on absolute-rare skin lesion datasets with an accuracy of 92.5%. Wilcoxon signed-rank test examines significant differences amid the proposed RT algorithm and conventional algorithms used in the experiment.Originality/valueExperimentation is performed on absolute-rare four skin lesion datasets, and the effectiveness of RT is assessed based on accuracy, sensitivity, specificity and area under curve. The performance is compared with an existing ensemble and boosting-based TL methods.
Monetary policy and house prices in emerging markets
Authors: Tunc Cengiz , Gunes Ali 
Published: June 2022

PurposeThis study aims to focus on two-way interaction between monetary policy and house prices in emerging economies.Design/methodology/approachThis study uses panel structural vector autoregressive model.FindingsThe results show that real house prices decrease in response to a contractionary monetary policy shock. However, relative to advanced economies, the reaction of the prices is limited in emerging economies, pointing out the structural differences in emerging economies including the small size of the mortgage market and the lack of a well-functioning secondary market in housing finance. This study further finds that monetary policy is tightened in response to a positive shock to house prices. However, this response is also weak when compared to that response in advanced economies.Research limitations/implicationsThese findings suggest that house price developments should not be prior target for monetary policies in emerging economies unless they become problem for financial stability or inflationary concerns.Originality/valueUsing a sample of inflation targeting emerging countries, this study contributes to the literature by conducting both panel setting and single-country analysis to explore the two-way dynamic relationships between the monetary policy and housing market in emerging economies.
On computation of reliability index for tensile membrane structures based on limit state of deflection
Authors: Rana Bhupendra Singh , Dutta Subhrajit , Maiti Pabitra Ranjan , Putcha Chandrasekhar 
Published: June 2022

PurposeThe present study is based on finding the structural response of a tensile membrane structure (TMS) through deformation. The intention of the present research is to develop a basic understanding of reliability analysis and deflection behavior of a pre-tensioned TMS. The mean value first-order second-moment method (MVFOSM) method is used here to evaluate stochastic moments of a performance function with random input variables. Results suggest the influence of modulus of elasticity, the thickness of the membrane, and edge span length are significant for reliability based TMS design.Design/methodology/approachA simple TMS is designed and simulated by applying external forces (along with prestress), as a manifestation of wind and snow load. A nonlinear analysis is executed to evaluate TMS deflection, followed by calculating the reliability index. Parametric study is done to consider the effect of membrane material, thickness and load location. First-order second moment (FOSM) is used to evaluative the reliability. A comparison of reliability index is done and deflection variations from μ − 3s to μ + 3s are accounted for in this approach.FindingsThe effectiveness of deflection is highlighted for the reliability assessment of TMS. Reliability and parametric study collectively examine the proposed geometry and material to facilitate infield design requirements. The estimated β value indicates that most suitable fabric material for a simple TMS should possess an elasticity modulus in the range of 1,000–1,500 MPa, the thickness may be considered to be around 1.00 mm, and additional adjustment of around 5–10 mm is suggested for edge length. The loading position in case of TMS structures can be a sensitive aspect where the rigidity of the surface is dependent on the pre-tensioning of the membrane.Research limitations/implicationsThe significance of the parametric study on material and loading for deflection of TMS is emphasized. Due to the lack of consolidated literature in the field combining reliability with deflection limits of a TMS, this work can be very useful for researchers.Practical implicationsThe present work outcome may facilitate practitioners in determining effective design methodology and material selection for TMS construction.Originality/valueThe significance of parametric study for serviceability criteria is emphasized. Parameters like pre-stress can be included in future parametric studies to witness in depth behavior of TMS. Due to lack of consolidated literature in the field combining reliability with deflection limits of a TMS, this work can be very useful for the researchers. The present work outcome may facilitate practitioners in determining effective design methodology and material selection for TMS construction.
Female veterinarians' experiences with human clients: the link to burnout and depression
Authors: Rhodes Regina L. , Noguchi Kenji , Agler Lin-Miao L. 
Published: June 2022

PurposePrevious research studies have noted that veterinarians are up to four times more likely to die by suicide than the general population. Studies have indicated possible catalysts for this increased risk, including exposure to euthanasia, depression, burnout, compassion fatigue, occupational stress, work–life imbalance and anxiety. With female veterinarians reporting higher rates of mental health issues and the fact that the ratio of female to male veterinarians is almost 2:1, the study focused on the female veterinarian population. Few research studies have been conducted to examine stressors directly related to human factors. The present study aims to examine the path to depression and burnout as it relates to positive versus negative interactions with human clients (owners of animal patients).Design/methodology/approachThe study recruited 222 female veterinarians online (average age = 36.89). The participants completed three scales measuring (1) burnout; (2) depression, anxiety and stress; and (3) positive and negative experiences with human clients.FindingsUsing the structural equation modeling (SEM), the results showed contrasting patterns of positive versus negative client-related experience in relation to burnout and depression. Positive client experience showed a direct path to the lower levels of depression and client-related burnout while negative client experience revealed a non-direct path to depression but a direct path to more specific burnout such as client-related and work-related burnout.Originality/valueResults of the study offered insight into the unique contribution of client-related experience in burnout and depression as positive versus negative client experience took on differential paths to depression and burnout.
On the lubrication performance of journal bearing coupled with the axial movement of journal
Authors: Li Biao , Sun Jun , Wang Hu , Zhang Xiao 
Published: June 2022

Purpose
Under the action of many factors, the shaft of the shaft-journal bearing system inevitably moves along the axis direction at work, which will lead to the axial movement of journal in the bearing. However, at present, only the dynamic and squeezing effects caused by the relative rotation and squeezing motion between the journal and the bearing surfaces are considered in the lubrication analysis of misaligned journal bearing and the axial movement of journal in the actual use of bearing is not considered. The purpose of this paper is to analyze the lubrication of journal bearing considering the axial movement of journal.

Design/methodology/approach
Taking the shaft-journal bearing system as the research object, a hydrodynamic lubrication model of journal bearing is established considering the axial movement and misalignment of journal. The finite difference method is used to solve the Reynolds equation for the lubrication analysis.

Findings
The axial movement of journal has a significant influence on the lubrication characteristics of misaligned journal bearing. The larger the misalignment angles of journal or the eccentricity of bearing, the greater the influence of the axial movement of journal on the lubrication performance of bearing. The lower the speed of bearing or the smaller the clearance of bearing, the more significant the influence of the axial movement of journal on the lubrication performance of bearing is.

Originality/value
The influence of the axial movement of journal on the lubrication performance of journal bearing is studied under different misalignment angles of journal, working conditions and clearances of bearing. The results of this paper are helpful to the design and research of the lubrication performance of journal bearing.
Learning communities and collaborative reflection for teaching improvement
Authors: Sajon Mariana Paz , Primogerio Paula Cecilia , Albarracin Mariana 
Published: June 2022

Purpose
This study covers an experience of teacher training carried out in an Undergraduate Business School from a private university in Buenos Aires, Argentina. The purpose of the project was to provide teachers with an opportunity to reflect on their teaching practices at the university. The aim of this study is to systematize lessons and challenges that emerge from this teacher training experience and get to know in which way this helped to improve student’s learning process.

Design/methodology/approach
A group of teachers, who showed willingness to learn teaching abilities, was selected. They worked in two learning communities that were organized by expertise: one community of the field of social sciences and one of the field of economic sciences. They completed a formative process that began by diving into a pedagogic topic, continued with class observations and finished with an individual and collaborative reflection exercise. They repeated this process with each of the topics in a systematic way among colleagues. In this study, the production of eight teacher’s e-portfolio and the expected product of their training journey are analyzed.

Findings
The analysis shows that after the process of shared reflection, traits related to powerful teaching and meaningful learning have appeared in the classes. Teachers reflect having reached an awareness of their own practices, identifying strengths and opportunities for improvement. The experience of sharing their own way and knowing the successes and failures of others was valued.

Originality/value
Teacher training programmes in business education are infrequent. This experience promotes a journey of pedagogical transformation for teachers of a Business School in Argentina, which could lead to a change in teaching practices for the entire Business School. The present study involves theoretical and pedagogical aspects of business education and its direct implications for the workplace, which may be transferred to other educational contexts.
Caring school leadership, school context and organizational learning: implications for developing professional capital
Authors: Ryu Jisu , Walls Jeff , Seashore Louis Karen 
Published: June 2022

PurposeThe purpose of this study is to examine how context shapes leaders' caring approach in ways that influence organizational learning and the cultivation of professional capital.Design/methodology/approachThis exploratory study draws on case study data from two schools. Within each school, the authors draw primarily on semi-structured interviews with teachers and leaders.FindingsThe authors found that school context and the accompanying leader beliefs shaped the structures and practices where organizational learning occurred, and thereby influence the diffusion of organizational learning in the school and the flexibility by which organizational lessons can be applied.Research limitations/implicationsThis research demonstrates that the context and place in which schools are situated influence how problems are apprehended and addressed. Leaders' relational approach, bounded by this context, influences how members of the school develop professional capacity. Larger scale studies would help clarify the nature of these effects.Originality/valueAlthough context has been shown to influence leadership, no study has examined the links between context, leaders' relational approach and organizational learning.
The influence of emotional intelligence and personal styles of dealing with conflict on strategic decisions
Authors: Alharbi Raed , Alnoor Alhamzah 
Published: June 2022

PurposeOrganizations seek to achieve the best results for their strategic decisions by increasing the effectiveness of the vertical and horizontal interconnection. This leads to an efficient and effective flow of information when making decisions (from the bottom-up) and information related to those decisions when starting to implement them on the ground (from Top-down). Thus, the article aims that, it requires managers at all levels to practice relational leadership skills, the most important of which is dealing with emotions (through emotional intelligence (EI)) and conflicts (through personal styles).Design/methodology/approachIn this paper the views of 324 managers were surveyed in several small and medium-sized companies in Saudi Arabia. The respondents were selected randomly.FindingsA direct positive effect of EI, patterns of cooperation and comprehension to deal with conflict was found on the results of strategic decisions and indirectly through relational leadership.Research limitations/implicationsThis paper is restricted to the relevant literature on the influence of EI and personal styles of dealing with conflict on strategic decisions.Practical implicationsAs part of the practical implication and managerial decision, policymakers should note that intelligence directly impacts strategic decisions.Originality/valueThis is one of the few studies that focused on the level of EI when choosing managers for organizational units and divisions.
Opportunistic diseases in marine eukaryotes: Could Bacteroidota be the next threat to ocean life?
Authors: Hudson Jennifer , Egan Suhelen 
Published: June 2022

AbstractBacteria within the phylum Bacteroidota (Bacteroidetes) are known to cause devastating and widespread disease outbreaks in marine eukaryotic hosts. However, with few pathogens described in detail, their prevalence and virulence strategies remain largely unknown. Here, we systematically reviewed the literature to evaluate the current understanding of Bacteroidota that cause disease in marine hosts. Isolates affiliated with the genera Tenacibaculum and Aquimarina (Flavobacteriaceae) were the most widely reported and characterized pathogens. Although cultured isolates were predominantly Flavobacteriia, culture‐independent studies also found classes Bacteroidia, Cytophagia and Sphingobacteriia associated with disease. We found that pathogenic marine Bacteroidota largely conformed to an opportunistic lifestyle but could also act as secondary pathogens or were involved in polymicrobial diseases. Many diseases were also associated with an environmental stressor, especially those affecting coral, macroalgae and fish. Key virulence traits included the production of adhesins and host tissue‐degrading enzymes. Overall, the nature of disease involving Bacteroidota pathogens appears to be an outcome of complex host–pathogen–environment interactions; however, our understanding of virulence remains limited by the lack of functional characterization studies. This is concerning as Bacteroidota have the potential to emerge as a serious threat to marine ecosystems and aquaculture industries, driven by global changes in ocean conditions.
Food web and metabolic interactions of the lung inhabitants Streptococcus pneumoniae and Pseudomonas aeruginosa
Authors: Sabra Wael , Wang Wei , Goepfert Christiane , Zeng An‐Ping 
Published: June 2022

AbstractBacteria that successfully adapt to different substrates and environmental niches within the lung and overcome the immune defence can cause serious lung infections. Such infections are generally complex, and recognized as polymicrobial in nature. Both Pseudomonas aeruginosa and Streptococcus pneumoniae can cause chronic lung infections and were both detected in cystic fibrosis (CF) lung at different stages. In this study, single and dual species cultures of Pseudomonas aeruginosa and Streptococcus pneumoniae were studied under well‐controlled planktonic growth conditions. Under pH‐controlled conditions, both species apparently benefited from the presence of the other. In co‐culture with P. aeruginosa, S. pneumoniae grew efficiently under aerobic conditions, whereas in pure S. pneumoniae culture, growth inhibition occurred in bioreactors with dissolved oxygen concentrations above the microaerobic range. Lactic acid and acetoin that are produced by S. pneumoniae were efficiently utilized by P. aeruginosa. In pH‐uncontrolled co‐cultures, the low pH triggered by S. pneumoniae assimilation of glucose and lactic acid production negatively affected the growth of both strains. Nevertheless, ammonia production improved significantly, and P. aeruginosa growth dominated at later growth stages. This study revealed unreported metabolic interactions of two important pathogenic microorganisms and shed new lights into pathophysiology of bacterial lung infection.
Bala wāsṭa: aspirant professionals, class‐making, and moral narratives of social mobility in Lebanon
Authors: İpek Yasemin 
Published: June 2022

AbstractWhile there is a growing anthropological interest in professionals as experts and powerful actors, there is little ethnographic inquiry into invocations of professionalism by less privileged communities. This article examines how professionalism in Lebanon was increasingly appropriated by low‐income communities in ways not referring to any particular profession or occupational domain. As a locally defined category, professionalism indexed an urban middle‐class subjectivity of performing specific sets of symbolic capital, moral dispositions, and cross‐sectarian relationalities. Lebanese civil society, led by middle‐class cultural elites, promoted professionalism as a moral alternative to reliance onwāsṭa(intermediary connections through family or kinship), a practice associated with a corrupt sectarian political system. What I call aspirant professionals – young, low‐income, university‐educated Lebanese – increasingly participated in empowerment NGOs to learn professionalism in pursuit of social mobility and respectability. Aspirant professionals did not simply emulate the middle‐class culture of professionalism; rather, their class‐making process generated its own moralities, subjectivities, and practices. Through a critical examination of aspirant professional subjectivity, this article contributes to anthropological studies on professionalism, NGOs, and class.
