Modified hexagonal pin fins for enhanced thermal-hydraulic performance of micro-pin fin heat sinks
Authors: Roozbehi Ahmad Reza , Zabetian Targhi Mohammad , Heyhat Mohammad Mahdi , Khatibi Ala 
Published: May 2023

Purpose
This numerical study aims to investigate the modification of the hexagonal pin fin geometry to enhance both the thermal and hydraulic performance of the copper micropin fin heat sink with single-phase water coolant in a laminar regime. The heat sink performance evaluation criteria have been investigated for the parametric effects of vertex angle θ (10–120) and relative length (RL) (0.25–9) of hexagonal pin fins.

Design/methodology/approach
To carry out research and reduce the computational cost, only one heat sink unit is simulated and analyzed using periodic boundary conditions on the side walls and includes a hexagonal pin fin and half channel on both sides to reflect the structural characteristics completely. The governing equations are also solved using finite volume method.

Findings
The results reveal that θ = 60 and RL = 1 yield the optimum thermal performance and heat sink performance is significantly influenced by the vertex angle and RL. The modified hexagon geometry improves fluid flow behavior by reducing the volume of the recirculation region behind the pin fin, preventing its effects on the downstream pin fins and restricting the thermal boundary layer development on its straight side. At Re = 1,000, the modified geometry enhances the average Nusselt number by 24.46% and the thermal performance factor by 23.89%, demonstrating the potential of modified hexagonal pin fins to enhance micropin fin heat sink performance.

Originality/value
Prior studies suggest using the pin fins with a regular hexagonal cross-section to obtain better thermal performance. However, this comes with a higher pressure drop penalty. The modification of the hexagonal pin fin geometry has been investigated in this numerical study to enhance both the thermal and hydraulic performance of the micropin fin heat sink. Because little attention has been paid to the modification of the regular hexagonal pin fins, as a geometry inspired by natural honeycomb structures, its design optimization is relatively scarce, and a gap was felt in this field.
Why are consumers dissatisfied? A text mining approach on Sri Lankan mobile banking apps
Authors: Sally Maas Sherina 
Published: May 2023

PurposeThe motivation of this study is to identify whether the overall rating of a banking app actually reflects the customer opinion and to find the causes for reduced ratings. Thus, these causes lead to the dissatisfaction of customers. Additionally, these insights reflect the overall rating of the app and it is a source of information to the executive management to contemplate on their services and take timely and effective decisions to improve their mobile app.Design/methodology/approachThis research was conducted on ten reputed Sri Lankan mobile banking apps to analyze the textual opinions of the customers. Data were collected from the Google Play Store considering the higher Android consumers in Sri Lanka. Each review was automatically classified into a relevant sentiment (positive, negative or neutral). These classified reviews were examined along with its rating to identify any discrepancies. The trends of the positive and negative reviews of each app were observed separately along with time. Topic modeling techniques were used to identify the causes of such behavior.FindingsAlthough banks expect to perpetuate good customer reviews all the time, there were aberrant negative trends observed during certain time ranges. The results revealed that unstable versions after recent updates, bad customer service, erroneous functional and nonfunctional features are the root causes toward the dissatisfaction of the customers.Originality/valueNo previous study has been done on the textual reviews of Sri Lankan mobile banking apps. Most studies had considered analyzing the reviews of the app on the entire period of its usage, whereas this research finds the trends where negative reviews surpass the positive reviews and analyze the causes of such behavior.
The relationship between physicians' ingroup favoritism to patients and workplace violence: regulatory role of physicians' psychological resilience
Authors: Okun Olcay , Arun Korhan 
Published: May 2023

PurposeThis research aims to reveal the relationship between ingroup favoritism, seen as a theoretical cause of workplace violence experienced by physicians, with pre-violence, the moment of violence and post-violence, and the role of psychological resilience in coping with workplace violence.Design/methodology/approachA descriptive, cross-sectional design was applied in the research. First, data was gathered via structured questionnaire surveys to the 169 physicians and 321 patients with appointments using the simple random sampling method in three public hospitals in the province of Sanliurfa-Turkey between June 3, 2020, and January 1, 2021. The data was then examined through variance-based structural equation modeling and regression analysis.FindingsResults indicate that the psychological resilience of physicians is essential in coping with workplace violence. The causes of favoritism behaviors were stated as a desire to protect the individuals they are with, increase their power, gain interest and cover their incompetence. It was determined that favoritism behaviors increase violence, but psychological resiliency decreases violence.Originality/valueSome unobservable markers that impose priority for a patient from one's primary group, favoritism, may predict behaviors including violence. Contrary to popular belief, violence against physicians may be prevented by hospital management and social psychology practices rather than taking legal actions or increasing physical safety procedures. Moreover, the simultaneous collection of the data used in the study from physicians and patients with an appointment makes the study more meaningful and unbiased.

Findings
In particular, it is noted that during the period of the destruction of the planned economic model and the choice of ways for the development of the economy, as well as at the initial stage of the transition period of the economy in Russia.

Originality/value
The author singles out the following patterns of development of criminal legislation in Russia: a) under the influence of a sharp change in the economic model, risks in the sphere of protection of economic relations; and b) the tasks of criminal law in the field of protection of economic relations are changing significantly: from protecting the state monopoly in most areas of economic activity to protecting market economic relations.
Is corporate social responsibility more valuable in disrupted industries?
Authors: Wang Liu , Wang Yong 
Published: May 2023

PurposeThe business world today is witnessing ever-growing disruption. This study highlights corporate social responsibility (CSR) as an effective strategy for firms in disrupted industries to consider in order to differentiate themselves and to increase their chance of survival facing disruption.Design/methodology/approachIn this study, the authors test the hypotheses using a multilevel modeling (MLM) design to capture the group and intergroup effects at the industry level and at the firm level. The empirical analysis is based on a panel sample of 1,193 firms over the 10-year period from 2010 to 2019.FindingsThe empirical analysis indicates that CSR has a positive impact on corporate financial stability and the effect is especially significant for firms in disrupted industries. Further investigation suggests that this positive effect largely runs through traits of the social pillar, such as human rights, employee relations, customer protection, product responsibility and community impact. The results are robust after controlling for other firm-specific characteristics and after addressing endogeneity concerns.Originality/valueThis study examines whether, and through which channel, CSR helps enhance corporate financial stability and mitigate bankruptcy risk in disrupted industries. To the best of the authors' knowledge, this study is the first attempt to explore the use of CSR as an effective strategic response to disruption. Further analysis indicates that the social capital built through CSR plays an important role in helping enhance corporate financial stability.
Accounting comparability and financial distress
Authors: Islam Mohammad Nazrul , Li Shihong , Wheatley Clark M. 
Published: May 2023

Purpose
The purpose of this study is to present the evidence of the association between financial statement comparability and corporate financial distress.

Design/methodology/approach
This is an empirical study, and this study uses multiple regression analysis to evaluate hypothesis.

Findings
The authors find a significant decrease in the probability of financial distress as accounting comparability increases. Findings of this study suggest that distressed firms tend to produce financial statements that compare poorly to those of peer firms; the effectiveness of predicting financial distress with accounting ratios may be conditional on comparability with peers; and financial statement comparability may be predictive of financial distress.

Research limitations/implications
First, this study only used publicly available financial data, which may not be representative of all countries and could differ because of differences in accounting practices. Second, although this study found a connection between accounting comparability and financial distress, it cannot prove a causal relationship, as other factors that were not controlled for may also have an impact. Third, this study used various measures of financial distress, but other measures could lead to different results. Finally, this study did not include all relevant variables, such as industry-specific factors and macroeconomic conditions, which could influence the relationship between accounting comparability and financial distress.

Practical implications
For investors and financial analysts, the results imply that accounting comparability can serve as a useful signal for identifying companies that are more likely to remain financially stable in the long run. Thus, they may prefer to invest in or recommend highly comparable firms over their less comparable counterparts. For auditors, this study underscores the importance of promoting and enforcing accounting standards that improve comparability, as this can help mitigate the risk of financial distress among their clients. Regulators may also consider the implications of the study’s findings when designing policies and guidelines related to financial reporting and disclosure.

Originality/value
To the best of the authors’ knowledge, this is the first study investigating the association between financial statement comparability and corporate financial distress of the US firms. This study uses large, comprehensive and multi-year data. Furthermore, this is the only study that presents the evidence of negative association between comparability and firm financial distress.
Shifting to a high impact practice-centered student worker staffed research desk: a Hispanic serving institution perspective
Authors: DeZouche Elizabeth , Santos Denise 
Published: May 2023

PurposeThe authors seek to demonstrate, from a Hispanic-serving institution (HSI) perspective, the importance of utilizing High Impact Practices (HIPs) for not only more meaningful student employment initiatives, but to benefit the campus community and prepare Hispanic students for success post-graduation.Design/methodology/approachEvaluation of current practices in academic libraries aided the design of the new staffing model, location and name. A survey of research desk student assistants was designed and implemented approximately one academic year after changes were executed. Survey data combined with follow-up interviews summarized the qualitative-focused assessment of the research desk's evolution and verified the validity of maintaining HIPs in libraries for Hispanic student success.FindingsThe transition of the reference desk to a student-staffed research desk was successful in that librarians were able to dedicate more time to other endeavors, such as campus outreach and collection development. The High Impact Practice (HIP)-focused desk model, along with new, customized onboarding and training materials, fulfilled their goals of giving student assistants meaningful employment on campus while also bridging the gap between the library and the mostly Hispanic, first-generation student population. An assessment from the student assistants' point of view helped them further analyze the new research desk model. They found that student assistants noticed the ease with which their peers approached the desk and how their skills learned on the research desk transferred to their classes and future careers.Research limitations/implicationsDue to the COVID-19 pandemic and the restructuring of library personnel the authors were unable to implement library patron surveys to evaluate the new desk model.Originality/valueMany academic libraries and partners have made the transition to student-staffed help desks or offer peer-to-peer tutoring or mentoring services. HIPs positively impact marginalized student populations scholastically, but no current studies discuss the effect on the Hispanic student population from an HSI perspective. This study illuminates the wholistic influence HIPs have on Hispanic student assistants, not only their work and peers, but the affect on their academic and personal lives.
Hybrid mineral model integrating probabilistic and machine learning approaches for the Brazilian pre‐salt carbonate reservoirs
Authors: de Oliveira Lucas Abreu Blanes , do Nascimento Freitas Gabriel , Pesce Pedro Barros Cotta , de Carvalho Carneiro Cleyton 
Published: May 2023

AbstractWell mineralogy can be estimated from probabilistic, direct and machine learning models; however, all these models have limitations. The maximum number of components in probabilistic models is restricted to the number of logs plus one. Direct models require the precise composition of minerals. Machine learning models demand unbiased databases, a challenge as the samples are collected in reservoir intervals. These limitations impact the evaluation for the Santos Basin pre‐salt rocks due to the complexity of facies and magnesian clays. This work proposes creating a hybrid model through the combination of probabilistic and machine learning models. First, mineral fractions of calcite, dolomite, quartz, k‐feldspar, detrital clay, plagioclase and pyroxene are estimated by the algorithm XGBoost trained using rock samples. Then, a probabilistic model reconstructs the well logs and machine learning estimations through the seven minerals mentioned plus magnesian clays, pyrite, barite and fluids. The difference between the real and reconstructed responses is minimized, weighted by the curves’ uncertainties. The hybrid model is used to estimate the mineralogy of three wells drilled in the Santos Basin, honouring the mineralogy of the rock samples collected in these wells and improving the quantification of dolomite, pyroxene and magnesian clay. Among the advances introduced, the following stand out: The use of machine learning estimates and well logs improved the quantification of magnesian clay; the machine learning estimates regularized the probabilistic model, generating more coherent results; the uncertainties of the machine learning algorithms dealt with database bias. The hybrid model mitigated limitations related to database bias without the costs associated with collecting more samples.
Quantitative Study of the Morphological Variations among Dzieduszyckia Populations from the Devonian Rongxian Formation, South China and their Influencing Factors

Published: May 2023

AbstractThe rhynchonellide brachiopod Dzieduszyckia Siemiradzki is widely distributed in the Lower Famennian strata, and exhibits a wide range of morphological variations among populations. 1272 autochthonous Devonian Rongxian Dzieduszyckia fossils were collected from three populations in South China, namely the Dazhai, Dalong, and Longmi sections. A series of quantitative morphological analyses were conducted to understand the morphological variation among populations and identify the triggers responsible for such variations. The results show that the Dazhai population differs significantly in morphospace from the Dalong and Longmi populations, while the latter two exhibit more similar morphological features, suggesting that geographic distribution may play a key role in affecting Dzieduszyckia morphology. The Longmi population shows a distinct morphospace from the Dazhai population and an overlapped morphospace with the Dalong population, indicating that habitat may not be the controlling factor. Lastly, the Dazhai and Dalong populations share some morphological similarities, but the Dazhai and Longmi populations occupy completely different morphospaces, indicating that evolution had a greater impact on phenotypic divergence than habitat. Our findings suggest that geographic distribution is the predominant factor influencing the morphological variation of Dzieduszyckia, while evolution and living habitat are less significant, the former of which might play a more important role.
Shedding light on a hot topic: Tuberisation in potato
Authors: Stockem Julia E. , de Vries Michiel E. , Struik Paul C. 
Published: May 2023

AbstractGrowing small seedling tubers from true seed, comparable with mini tubers, in controlled conditions could be a method to multiply healthy starting material of potato. In indoor farming systems, the conditions can be optimised for high production. In field trials, it is impossible to investigate the effects of environmental factors such as temperature and light separately. In this study, we performed three climate room experiments in which the effects of light intensity, temperature and percentage of far‐red light in the light spectrum on tuber production were assessed. We found that increasing the average temperature reduced tuber number and tuber weight. Increasing the diurnal temperature variation while keeping the average temperature equal resulted in increased tuber size. The light treatments on the other hand only affected the number of tubers per plant: increasing light intensity and increasing the percentage of far‐red light in the spectrum enhanced the number of tubers. Moreover, interaction in tuber production between inbred lines and temperature was significant, with some inbred lines being relatively tolerant to high temperature. These findings will help breed for heat tolerant varieties and optimise growing conditions for tuber production in indoor farming systems.
Cognitive style and creativity: The role of education in shaping cognitive style profiles and creativity of adolescents
Authors: Ho Shuen , Kozhevnikov Maria 
Published: May 2023

AbstractBackgroundPrevious research on cognitive styles (CSs) has often overlooked their complexity and the effect of the environment on their development. While research supports visual abilities as predictors of domain‐specific creativity, there is a lack of studies on the predictive power of CS in relation to creativity beyond abilities.AimsThe current study aimed to explore the validity of the CS construct as environmentally sensitive individual differences in cognition. We examined the internal structure of the CS construct, its predictive power in creativity beyond visual abilities, and how CSs of Singaporean secondary school students are shaped with age under specific sociocultural influences (Singapore's emphasis on STEM disciplines).SampleData were collected from 347 students aged 13–16 from a secondary school in Singapore.MethodsStudents were administered nine tasks assessing their visual abilities and learning preferences, artistic and scientific creativity, and questionnaires assessing their CS profiles.ResultsThe confirmatory factor analyses provided evidence for a matrix‐type CS structure consisting of four orthogonal CS dimensions and third levels of information processing. Structural equation models demonstrated significant contributions of context independence and intuitive processing to artistic and scientific creativity, respectively, beyond visual abilities. The results also suggested that Singapore's education system could be contributing to significantly shaping adolescents' CS profiles.ConclusionsOur findings support the validity of CS as individual differences in cognition that develop to cope with environmental demands. They highlight the importance of providing an appropriate environment in shaping adolescents' CS profiles to support the development of domain‐specific creativity according to their strengths and talent.

SummaryIn high‐risk myeloid malignancy, relapse is reduced using cord blood transplant (CBT) but remains the principal cause of treatment failure. We previously described T‐cell expansion in CBT recipients receiving granulocyte transfusions. We now report the safety and tolerability of such transfusions, T‐cell expansion data, immunophenotype, cytokine profiles and clinical response in children with post‐transplant relapsed acute leukaemia who received T‐replete, HLA‐mismatched CBT and pooled granulocytes within a phase I/II trial (ClinicalTrials.Gov NCT05425043). All patients received the transfusion schedule without significant clinical toxicity. Nine of ten patients treated had detectable measurable residual disease (MRD) pre‐transplant. Nine patients achieved haematological remission, and eight became MRD negative. There were five deaths: transplant complications (n = 2), disease (n = 3), including two late relapses. Five patients are alive and in remission with 12.7 months median follow up. Significant T‐cell expansion occurred in nine patients with a greater median lymphocyte count than a historical cohort between days 7–13 (median 1.73 × 109/L vs. 0.1 × 109/L; p < 0.0001). Expanded T‐cells were predominantly CD8+ and effector memory or TEMRA phenotype. They exhibited markers of activation and cytotoxicity with interferon‐gamma production. All patients developed grade 1–3 cytokine release syndrome (CRS) with elevated serum IL‐6 and interferon‐gamma.
