Authors: Adeyemi Bashir Ademola , Ebegbetale Christopher Idemudia , Showemimo Ibrahim Olanrewaju 
Published: July 2024

Purpose
Managing patients’ health information is one of the building blocks of the health system and the adoption of health information technologies like electronic health records (EHRs) is expected to reduce the various challenges in keeping and accessing quality health-care data that aid decision-making among medical practitioners. This study aims to investigate how leadership styles and change management affected the job performance of health information management practitioners on their adoption of EHRs in tertiary hospitals in Nigeria.

Design/methodology/approach
The study used primary data collected using a Likert scale questionnaire from 117 health information management officers and health information technicians in selected tertiary hospitals in South-Eastern Nigeria. The data were analysed using bivariate correlation and multiple regression techniques of inferential statistics.

Findings
The analyses revealed that transformational leadership style, transactional leadership style and change management had significant positive influence on the job performance of health information management practitioners. However, laissez-faire leadership style did not show any significant positive influence. A further analysis showed that the combined effects of leadership styles and change management were also affirmed to significantly influence the adoption of EHRs for quality health-care delivery in Nigerian tertiary hospitals.

Originality/value
The study contributes to health information management and the need to understand how leadership styles and change management can influence the adoption of EHRs. However, there is no adequate research that examined the role of leadership style and change management in influencing the job performance of Nigerian HIM practitioners regarding their usage of EHRs in tertiary hospitals in Nigeria.
Leadership dynamics in nursing: a comparative study of paternalistic approaches in China and Pakistan
Authors: Safdar Samyia , Faiz Shazia , Mubarak Namra 
Published: July 2024

Purpose
This study aims to examine the impact of nurses’ paternalistic leadership style on performance, in the presence of underlying mechanisms, i.e. self-efficacy as a mediator in the high-power distance societies, namely, China and Pakistan, based on social exchange theory. Both healthcare sectors have seen several behavioral advancements in recent years. To improve things, even more, behavioral elements such as the influence of leadership styles, personality traits and so on have become more important. However, leadership styles, particularly paternalistic leadership, have received little attention in this field and need to be highlighted along with the mediating and moderating effects.

Design/methodology/approach
Data were collected from public and private sector hospitals in China and Pakistan using a 6-week time lag technique. Firstly, 356 Chinese and 411 Pakistani nurses were surveyed about their perceptions of power distance, self-efficacy and paternalistic leadership. Their managers were called six weeks later for a dyadic response to provide feedback on nurses’ performance. For confirmatory factor analysis, AMOS 22 and for regression analysis, SPSS 22 was used.

Findings
According to the study's findings, nurses in both countries perform well when led by a paternalistic leader. Furthermore, self-efficacy explains the relationship between paternalistic leaders and nurses’ performance. The moderated-mediation result also supported the importance of power distance.

Originality/value
This study highlights the kind of nursing leadership which is beneficial in high-power-distance societies and leads to better performance. According to this research, paternalistic leadership improves nurses’ performance in both China and Pakistan. As a result, this study will be useful in high-power-distance societies, where hospital administrators can ensure that paternalism is implemented in leadership, thereby improving nurse performance.

Authors: Oh Sanghee , Syn Sue Yeon 
Published: July 2024

PurposeThis study aimed to examine the impact of perceived risks of COVID-19 and users’ intention to continually use social media for COVID-19 information, thereby revealing social media users’ perceptions and behaviors regarding the pandemic.Design/methodology/approachThe Health Belief Model was used to develop the research model. Data were collected from social media users in Korea using an online survey.FindingsThe findings showed that social media users’ intention to continually use social media for COVID-19 information explained 46.5% of the variance in their perceived severity, perceived susceptibility, perceived benefits, and perceived barriers. The degree of impact and relationships varied across the constructs. Two age groups were examined, and it transpired that perceived risks and perceived use were more highly recognized by young users than old users.Research limitations/implicationsThis study focused on Korean social media users, providing valuable insights but limiting its generalizability. The proposed research model and methodology can include participants from various countries or cultures to enhance global relevance and diversified perspectives on how perceived risks impact social media use for health information.Practical implicationsThis study’s findings can be used to provide tailored health information services to those with different levels of perceived risks, social media use, and different age groups.Originality/valueThis study adopted the Health Belief Model to understand users’ perceptions of COVID-19 information on social media and examined users’ intentions to continue using social media as a channel for COVID-19 information.
Does firm-level teamwork culture affect cash holdings?
Authors: Sinha Rajesh Kumar , Damle Harshali 
Published: July 2024

PurposePrior literature on the cultural determinants of cash holdings focuses on time-invariant cultural variables measured at the geographical level. These measures of culture do not capture the firm-level variation in corporate culture. Using a validated time-variant measure of firm-level corporate culture, specifically teamwork, we examine the effect of teamwork on a firm's cash holdings.Design/methodology/approachIn this paper, we explore the effect of corporate teamwork culture on firms' cash holdings. Using sudden CEO turnover as an exogenous shock to a firm's teamwork culture, we find teamwork increases cash holdings. Also, we test and find two channels—financial constraint and agency—and two new labour-related channels—human capital quality and labour inefficiency—through which teamwork culture affects cash holdings. Our results are robust to endogeneity tests.FindingsWe find that teamwork increases the cash holdings of firms. We find that a firm with a high teamwork culture has higher cash holdings: an increase of one standard deviation in teamwork leads to a 14.6% rise in the mean cash holdings.Originality/valueTo our knowledge, our study is the first to introduce the firm-level teamwork cultural construct as a determinant of cash holdings.
Multilayer polyester tire cord fabrics reinforced gamma irradiated SBR/devulcanized waste rubber: impact of fabric layers and devulcanization methods
Authors: Raslan Heba , El-Nemr Khaled , Ali Magdy , Hassan Medhat 
Published: July 2024

Purpose
This study aims to investigate the influences of polyester fabric layers on the mechanical properties of SBR and devulcanized waste rubber composite materials, as well as the effect of gamma irradiation dose.

Design/methodology/approach
The devulcanized waste rubbers (DWR) were carried out by different methods. First, chemically, by two different reclaiming agents such as tetramethylthiuram disulfide (TMTD) and 2-mercapto benzothiazole disulfide (MBTS). Secondary by a physical method like microwave (MW). The devulcanized rubbers were mixed with virgin styrene butadiene rubber (SBR) in different ratios, as follows: SBR-DWR (TMTD) 50 / 50, SBR-DWR (MBTS) 80 / 20 and SBR-DWR (MW) 80 / 20. A series of sandwich polyester tire cord fabrics were used as reinforcement for making SBR and devulcanized waste rubber composite materials and molded on a hot press into rubber sheet films, then subjected to gamma radiation at different doses ranging from 100 up to 200 kGy.

Findings
The experimental results indicate that increasing the layer number improves the mechanical properties of composites. The tensile strength, tearing, hardness and elastic modulus of the rubber composites increased with the rise of the fiber layers and by increasing the irradiation dose up to 200 kGy. The reclaiming agent TMTD gave the best results for mechanical properties, followed by MW and then MBTS.

Originality/value
This phenomenon can be detailed based on the fact that when the fiber-reinforced composites are subjected to loading, the fibers act as load carriers, depending on the population and orientation of the fibers. Also, scanning electron microscopy (SEM) reveals that adhesion was caused by tire cord fabrics and rubber blend matrix.

Authors: Enes Kemal 
Published: July 2024

PurposeThis study investigates the roles of technological development, artificial intelligence (AI), and robots in the catering business and their effects on the labor force and staff shortages.Design/methodology/approachThe impact of AI, robots, and technological advancements on the labor force is outlined. Secondary sources and the results of interviews with two highly experienced experts were used to identify the transformation or metamorphosis that affects the staff situation during catering operations. This is an opinion paper that explains why it contains many of the authors’ observations and experiences.FindingsTechnological equipment and AI have been used frequently in catering operations, and robots are not grooved. In the near future, these tools could be part of a solution for the staff shortage because, with their help, less-skilled workers could be doing some of the job in the catering business.Research limitations/implicationsThe study is written from a limited perspective because of its qualitative nature and the fact that it is shaped by expert opinions and the author's views. It is expected that conducting the same study with a larger number of experts operating in various fields on similar topics in the future will lead to more effective results.Practical implicationsThis research character is an opinion paper and qualitative. This research aims to explain the use of artificial intelligence, technological advancements, and robots and to explore their impacts on the labor force based on the opinions of experts and the author. The data obtained are expected to be useful for future labor force planning in catering businesses.Social implicationsThis study provides an exploratory framework regarding staff shortages in catering businesses and the integration of technology, AI and robots.Originality/valueBased on a literature review, only a limited number of studies have been conducted on the use of technology, artificial intelligence, and robots in kitchens. None of these studies investigated their impact on the labor force. Therefore, this study is both original and valuable.
Analytical and numerical examinations on the stability investigation of Casson nanofluid flow in a permeable layer controlled by vertical throughflow
Authors: Mohamad A.M. , Yadav Dhananjay , Awasthi Mukesh Kumar , Ragoju Ravi , Bhattacharyya Krishnendu , Mahajan Amit 
Published: July 2024

Purpose
The purpose of the study is to analytically as well as numerically investigate the weight of throughflow on the onset of Casson nanofluid layer in a permeable matrix. This study examines both the marginal and over stable kind of convective movement in the system.

Design/methodology/approach
A double-phase model is used for Casson nanofluid, which integrates the impacts of thermophoresis and Brownian wave, whereas for flow in the porous matrix the altered Darcy model is occupied under the statement that nanoparticle flux is disappear on the boundaries. The resultant eigenvalue problem is resolved analytically as well as numerically with the help of Galerkin process with the Casson nanofluid Rayleigh–Darcy number as the eigenvalue.

Findings
The findings revealed that the throughflow factor postpones the arrival of convective flow and reduces the extent of convective cells, whereas the Casson factor, the Casson nanoparticle Rayleigh–Darcy number and the reformed diffusivity ratio promote convective motion and also decrease the extent of convective cells.

Originality/value
Controlling the convective movement in heat transfer systems that generate high heat flux is a real mechanical challenge. The proposed framework proved that the use of throughflow is one of the most important ways to control the convective movement in Casson nanofluid. To the best of the authors’ knowledge, no inspection has been established in the literature that studies the outcome of throughflow on the Casson nanofluid convective flow in a porous medium layer. However, the convective flow of Casson nanofluid finds many applications in improving heat transmission and energy efficiency in a range of thermal systems, such as the cooling of heat-generating elements in electronic devices, heat exchangers, pharmaceutical practices and hybrid-powered engines, where throughflow can play a significant role in controlling the convective motion.

AbstractObjectiveMost cases of hepatocellular carcinoma (HCC) arise as a consequence of cirrhosis. In this study, our objective is to construct a comprehensive diagnostic model that investigates the diagnostic markers distinguishing between cirrhosis and HCC.MethodsBased on multiple GEO datasets containing cirrhosis and HCC samples, we used lasso regression, random forest (RF)‐recursive feature elimination (RFE) and receiver operator characteristic analysis to screen for characteristic genes. Subsequently, we integrated these genes into a multivariable logistic regression model and validated the linear prediction scores in both training and validation cohorts. The ssGSEA algorithm was used to estimate the fraction of infiltrating immune cells in the samples. Finally, molecular typing for patients with cirrhosis was performed using the CCP algorithm.ResultsThe study identified 137 differentially expressed genes (DEGs) and selected five significant genes (CXCL14, CAP2, FCN2, CCBE1 and UBE2C) to construct a diagnostic model. In both the training and validation cohorts, the model exhibited an area under the curve (AUC) greater than 0.9 and a kappa value of approximately 0.9. Additionally, the calibration curve demonstrated excellent concordance between observed and predicted incidence rates. Comparatively, HCC displayed overall downregulation of infiltrating immune cells compared to cirrhosis. Notably, CCBE1 showed strong correlations with the tumour immune microenvironment as well as genes associated with cell death and cellular ageing processes. Furthermore, cirrhosis subtypes with high linear predictive scores were enriched in multiple cancer‐related pathways.ConclusionIn conclusion, we successfully identified diagnostic markers distinguishing between cirrhosis and hepatocellular carcinoma and developed a novel diagnostic model for discriminating the two conditions. CCBE1 might exert a pivotal role in regulating the tumour microenvironment, cell death and senescence.
Cone beam computed tomography and cross‐sectional anatomy of the region of the fetlock in the horse (Equus caballus)
Authors: Bierau Jonathan , Rott Patricia , Röcken Michael , Staszyk Carsten 
Published: July 2024

AbstractThis study aimed to delineate the detailed anatomy of the metacarpophalangeal (MCP) and metatarsophalangeal (MTP) joints in healthy horses using cone beam computed tomography (CBCT). The fetlock region of 15 cadaveric forelimbs and 14 cadaveric hindlimbs from nine adult horses without orthopaedic disease underwent CBCT scanning. Additionally, arthrography CBCT scans were conducted following intra‐articular injection of a radiopaque contrast medium containing blue epoxy resin dye. Subsequently, limbs were frozen and sectioned to visualize anatomical structures in sectional planes corresponding to selected CBCT images. CBCT proved suitable for detailed visualization of the bony components of the fetlock region. Furthermore, the common digital extensor tendon, superficial and deep digital flexor tendons, suspensory ligament, and straight and oblique sesamoidean ligaments were identifiable on CBCT images. However, certain ligaments, such as the collateral sesamoidean ligaments and intersesamoidean ligaments, were not clearly identified. The hyaline cartilage of the MCP and MTP joint facets was assessable on the post‐contrast sequence. In cases where a radiographic or ultrasound examination cannot provide a definitive diagnosis and determine the extent of disease, CBCT can provide additional valuable data on the equine MCP and MTP joint. The images obtained in this study can serve as a reference for CBCT examination of the equine MCP and MTP joint.

Published: July 2024

AbstractAt the top of many ecosystems, raptors, also known as birds of prey, hold major influence. They shape their surroundings through their powerful hunting skills and complex interactions with their environment. This study investigates the beak morphology of four prominent raptor species, Golden eagle (Aquila chrysaetos), Common buzzard (Buteo buteo), Peregrine falcon (Falco peregrinus) and Common kestrel (Falco tinnunculus), found in Türkiye. By employing geometric morphometric methods, we investigate shape variations in the beaks of these species to unravel the adaptive significance of their cranial structures. This analysis reveals distinct beak morphologies among the studied raptors, reflecting adaptations to their feeding habits, hunting techniques and ecological niches. The results from Principal component analysis and Canonical variate analysis demonstrate significant differences in beak morphology between the Falconiformes and Accipitriformes clades, as well as among all three groups. The overall mean beak shapes of Golden Eagles are quite similar to Common Buzzards, with both species having longer beaks. In contrast, Falcons exhibit a distinctly different beak morphology, characterized by wider and shorter beaks. Changes in beak shape can lead to changes depending on the skull. It is thought that skull shape variations among predator families may have an impact on beak shape. These findings highlight the importance of integrating morphometric analyses with ecological insights to enhance our understanding of the evolutionary processes shaping raptor beak morphology.

AbstractPersonal growth and self‐expressive goals have become increasingly important in modern marriages. In dual‐earner couples, sharing work‐related experiences with the partner can be particularly important in promoting mutual support for each other's personal growth. The current study examined dual‐earner couples' sharing of work‐related experiences and how it influenced both partners' relationship satisfaction and personal well‐being. A total of 102 heterosexual dual‐earner couples were recruited from communities in Hong Kong. They completed a pretest survey, a 14‐day daily diary study, and a follow‐up survey 1 year later. The Actor‐Partner Interdependence Model was adopted to analyze the dyadic effects of sharing positive and negative work‐related experiences on relationship satisfaction and personal well‐being on the same day and 1 year later. In general, the sharing of both positive and negative work‐related experiences had beneficial effects on the outcomes. Specifically, wives' sharing had more immediate effects on both partners' relational and personal well‐being, whereas husbands' sharing had more long‐term effects on the partner's personal well‐being. The findings highlight the importance of work‐related sharing in dual‐earner couples. Practical implications are discussed.

AbstractA painted wooden shield from the 16th century, commonly traced back to the famous Lepanto Battle (1571), was investigated by a multi‐analytical approach to identify its manufacturing process and shed light on its cultural provenance. The typology is coherent with both the Christian and Ottoman armies and does not allow for an attribution. Radiocarbon dated the shield to two time intervals (1470–1525, 1580–1625, at 68% level of probability), compatible with the date of the Battle of Lepanto. Optical and Scanning Electron Microscopy, Attenuated Total Reflectance, External Reflection Fourier Transform Infrared, micro‐Raman and Energy Dispersive X‐ray Spectroscopy, and histochemical and shrinking temperature tests were used to characterize the artefact. The shield resulted to be made of softwood panels, covered by a stratigraphy of flax fibres, cattle skin, and a painting preparation layer of hydromagnesite. Adhesion was ensured by bone glue. Oblique, red, and cinnabar stripes alternating on the white preparation are visible on the front of the shield, whereas a homogeneous dark paint covers the back. None of the raw materials was informative by themselves, but the unusual presence of the hydromagnesite could be crossed with the geographical context, resulting in a promising outcome for future isotopic and trace element studies.
Employment systems in the twenty‐first century
Authors: Gahan Peter , Turnbull Peter 
Published: July 2024

AbstractIn this article, we honour David Marsden's most important contribution: his Theory of Employment Systems (ToES). Grounded in standard economic analysis, ToES sets out to explain how a relatively small number of employment systems solve fundamental problems associated with open‐ended employment relationships (flexibility and opportunism). In the period since its publication, the employment relationship remains the dominant form of engaging workers; however, employment arrangements in the UK and elsewhere have been transformed, and employment systems in many settings more closely resemble configurations of rules that ToES predicted would prove unstable. While ToES does not explicitly integrate a number of important dimensions that define all aspects of employment systems, we show why Marsden's core theoretical insights retain analytical purchase as an explanatory framework. That said, taking a more sociologically and historically informed approach to understanding contemporary employment systems is required to comprehend the diversity of employment systems and how they evolve in the twenty‐first century.
