Authors: Saba Munir  , Umair Khalid  
Published: December 2024

Financial resources are essential for business growth and attainment of competitive advantage. The effective allocation and usage of financial resources play a decisive role in ensuring businesses' long-term survival and competitive advantage across the world in all industries. Healthcare sector is of core importance due to its dynamic and ever evolving character. Like every other country, KSA puts a lot of attention to the healthcare industry and effective financial management has gained importance. The study aims to check the association among financial leverage, working capital efficiency and performance of the firm. Six mega healthcare firms that are listed the Saudi Stock Exchange (Tadawul) were selected for sampling from 2014-2022. The results of regression and correlations tests show a goodness of fit or R2 shows 40%and 52% effect of WC on returns and equity of the companies, whereas coefficient shows 0.00039 and 0.00073 negative impact on assets and equity returns. The current research results highlighted a negative association among WCM and companies returns. The study further concluded that FL has a positive effect on CCC, implying that increased financial leverage (FL) and working capital management (WCM) factors had negatively influenced both returns on assets and equity. Effectively managing working capital contributed to improved financial performance. Therefore, findings and results suggested that healthcare organizations better use the best working capital management practices to reach up to optimized performance and returns.

Published: December 2024

The study examines the influence of intellectual capital on the relationship between agency costs and firm performance using a sample of Asian agricultural firms. The study uses value added intellectual coefficient (VAIC) as a proxy of intellectual capital, which is based on human capital efficiency, structural capital efficiency and employed physical capital efficiency. Using the data of 9 Asian economies, the findings suggest that intellectual capital, in general, neutralizes the negative effects of agency cost on firm performance. Further analysis reveals that human capital efficiency and capital employed efficiency mitigate while structural capital efficiency has no impact on the negative relationship between agency cost and firm performance. These findings are robust to several robust tests. Overall, the study contributes to the resource-based view of intellectual capital by documenting how firms might neutralize the negative relationship between agency cost and firm performance while emphasizing intellectual capital.

Published: December 2024

Hiperurisemia merupakan gangguan metabolik yang sering terjadi pada lansia, ditandai dengan peningkatan kadar asam urat dalam darah yang dapat menyebabkan penyakit gout dan komplikasi lainnya. Salah satu faktor yang dapat memengaruhi kadar asam urat adalah aktivitas fisik. Namun, hubungan antara tingkat aktivitas fisik dan kadar asam urat pada lansia masih memerlukan penelitian lebih lanjut, khususnya di wilayah dengan karakteristik populasi spesifik seperti Kecamatan Tanjung Bumi, Kabupaten Bangkalan. Penelitian ini bertujuan untuk mengeksplorasi hubungan antara aktivitas fisik dan kadar serum asam urat pada lansia di Kecamatan Tanjung Bumi, Kabupaten Bangkalan, Jawa Timur. Asam urat yang tinggi dapat menyebabkan gangguan kesehatan seperti gout, terutama pada usia lanjut. Penelitian ini menggunakan desain cross-sectional melibatkan 259 lansia dengan pengukuran aktivitas fisik melalui kuesioner dan kadar asam urat menggunakan alat pengukur asam urat. Analisis statistik dilakukan untuk menentukan hubungan antara tingkat aktivitas fisik dan kadar asam urat dalam darah. Hasil penelitian menunjukkan bahwa mayoritas responden (61,8%) memiliki tingkat aktivitas fisik tinggi, dan 64,1% responden tidak mengalami hiperurisemia. Analisis statistik menunjukkan hubungan yang signifikan antara tingkat aktivitas fisik dengan kadar serum asam urat (p-value = 0,000). PRR menunjukkan bahwa risiko hiperurisemia pada lansia dengan aktivitas fisik tinggi adalah 0,191 kali dibandingkan lansia dengan aktivitas fisik rendah (95% CI: 0,130-0,281). Aktivitas fisik yang lebih tinggi berhubungan dengan kadar serum asam urat yang lebih rendah pada lansia di Kecamatan Tanjung Bumi, Kabupaten Bangkalan. Temuan ini menyoroti pentingnya promosi aktivitas fisik sebagai strategi pengelolaan hiperurisemia pada lansia. Penelitian lebih lanjut dengan desain longitudinal diperlukan untuk mendukung hasil ini.

Published: December 2024

Esse artigo trata-se de uma revisão bibliográfica, que teve como objetivo discutir os conceitos que compõem a teoria da identidade, a considerar a identidade, a autoidentidade e a diferença, levando em conta que se trata de um tema com fundamental importância para o entendimento a respeito da nossa constituição, enquanto ser social, cultural e histórico. Trata-se de uma pesquisa qualitativa e bibliográfica, cujo referencial teórico pautou-se em estudiosos da área, tais como como Stuart Hall, Antony Giddens e Vera Candau. A identidade social forma-se num processo de reconhecimento, que identifica ou diferencia o sujeito, ou seja, não é algo preexistente, mas que passa por situações culturais, sociais e históricas, o que garante, constantemente, a sua construção e reconstrução. Esta discussão faz-se relevante, tendo em vista que é um tema central para que o sujeito compreenda a si mesmo e ao contexto em que se encontra. o estudo possibilitou-nos perceber que a identidade é construída em diferentes contextos, de maneira individual e coletiva, por meio de experiências vividas, que são processadas ao longo da vida.
Road traffic delays in commuting workplace and musculoskeletal health among sedentary workers: A cross-sectional study in Dhaka city
Authors: Ali Mohammad , Ahsan Gias U , Uddin Zakir , Hossain Ahmed 
Published: November 2021

Abstract

Objectives
Despite previous research aimed at identifying factors linked to musculoskeletal health issues, there was no evidence about the relationship between road traffic delays (RTDs) and musculoskeletal health in sedentary employees. As a result, the aim of our research was to understand such a correlation among bank employees in Dhaka, Bangladesh.

Methods
A cross-sectional analysis was conducted with bank employees who worked in sedentary settings. The Eriksen subjective health complaints scale was used to measure the eight items of musculoskeletal health complaints (MHCs), and RTDs were measured using principal component analysis using variables commute time, distance, and traffic congestion experience to work. The association between RTDs and MHCs was identified using a multilevel model after adjusting potential confounders.

Results
A total of 628 employees (mean[SD] age, 36.1[7.0] years; 254[40.5%] women) participated in the study. Among the employees, the one-month prevalence of MHCs was 57.2%. The highest prevalence of MHCs was low-back pain (36.6%), followed by neck pain (22.9%) and upper-back pain (21.2%). Also, 136(21.7%) employees reported long-RTDs in commuting workplace and 81% of them had MHCs. The multilevel analysis identified that long-RTDs had a significant relationship with MHCs (adjusted odds ratio, AOR = 10.20, 95%CI = 5.41–16.91). Private transportation commuters reported 70% reduced odds of MHCs (AOR = 0.30, 95%CI = 0.15–0.59) and walking or bicycling commuters had 84% fewer MHCs (AOR = 0.16, 95%CI = 0.10–0.28) compared to public bus commuters.

Conclusions
Sedentary employees with long-RTDs reported increased MHCs, emphasizing the importance of including musculoskeletal exercise in office facilities. Findings of this study also highlight the need for a sound public transportation system in Dhaka city.

Published: November 2021

AbstractTraditionally, organic chemical reactions require organic solvents, toxic catalysts, heat, or high pressure. However, copper‐free click chemistry has been shown to have favorable reaction rates and orthogonality in water, buffer solutions, and physiological conditions without toxic catalysts. Strain‐promoted azide‐alkyne cycloaddition and inverse electron‐demand Diels–Alder reactions are representative of copper‐free click chemistry. Artificial chemical reactions via click chemistry can also be used outside of the laboratory in a controllable manner on live cell surfaces, in the cytosol, and in living bodies. Consequently, copper‐free click chemistry has many features that are of interest in biomedical research, and various new materials and strategies for its use have been proposed. Herein, recent remarkable trials that have used copper‐free click chemistry are described, focusing on their applications in molecular imaging and therapy. The research is categorized as nanoparticles for drug delivery, imaging agents for cell tracking, and hydrogels for tissue engineering, which are rapidly advancing fields based on click chemistry. The content is based primarily on the experience with click chemistry‐based biomaterials over the last 10 years.

Published: November 2021

AbstractComplex morphology in organic photovoltaics (OPVs) and other functional soft materials commonly dictates performance. Such complexity in OPVs originates from the mesoscale kinetically trapped non‐equilibrium state, which governs device charge generation and transport. Resonant soft X‐ray scattering (RSoXS) has been revolutionary in the exploration of OPV morphology in the past decade due to its chemical and orientation sensitivity. However, for non‐fullerene OPVs, RSoXS analysis near the carbon K‐edge is challenging, due to the chemical similarity of the materials used in active layers. An innovative approach is provided by nitrogen K‐edge RSoXS (NK‐RSoXS), utilizing the spatial and orientational contrasts from the cyano groups in the acceptor materials, which allows for determination of phase separation. NK‐RSoXS clearly visualizes the combined feature sizes in PM6:Y6 blends from crystallization and liquid–liquid demixing, while PM6:Y6:Y6‐BO ternary blends with reduced phase‐separation size and enhanced material crystallization can lead to current amplification in devices. Nitrogen is common in organic semiconductors and other soft materials, and the strong and directional N 1s → π* resonances make NK‐RSoXS a powerful tool to uncover the mesoscale complexity and open opportunities to understand heterogeneous systems.

AbstractSolar cells with a visually aesthetic functionality are of great importance for their smooth integration with indoor and outdoor spaces in buildings and automobiles, and portable electronic devices. Here bidirectional, colorful perovskite solar cells with high efficiency based on optical interference effects within the multilayer solar cell structure are presented. Tunable reflective colors across the whole visible region can be achieved by simply tuning the thickness of a transparent electrode of the solar cell. Same or different colors from top‐ and bottom‐sides can be easily attained by properly selecting the thickness of the transparent electrode. Absorbing a substantial fraction of the visible region of solar radiation allows the colored perovskite solar cells to accomplish high power conversion efficiencies of 16.01% and 17.68% when illuminated from the top‐ and bottom‐sides, respectively, while the reflective colors are produced by using a small proportion of the visible solar spectrum. The described scheme opens a variety of potential applications, such as power‐generating surfaces for buildings and automobiles, energy‐efficient display systems, and self‐powered wearable electronics.

Published: November 2021

AbstractTurnpenny‐Fry syndrome is a very rare genetic disorder characterized by intellectual disability, developmental delay, facial dysmorphism, and skeletal abnormalities. Mutations of the PCGF2 gene are responsible for Turnpenny‐Fry syndrome. This gene encodes the polycomb group ring finger 2 protein that is broadly expressed in various human tissues. To date, only 13 patients with Turnpenny‐Fry syndrome have been reported. Our patient was referred to our clinic for neuromotor retardation and dysmorphic features. Whole exome sequencing (WES) was performed from the peripheral blood sample of the patient. WES revealed a heterozygous mutation in the PCGF2 gene. To the best of our knowledge, we reported the 14th patient with Turnpenny‐Fry syndrome and the first from Turkey, who had new findings.

AbstractObjectivesThe anatomical features of the atlanto‐occipital joint can be potentially useful in re‐associating or excluding crania to atlases in commingled remains. This study investigated whether linear measurements and the 3‐dimensional (3D) surface of occipital condyles and articular facets of atlases can represent valid insights for this purpose.MethodsThe variations among eight corresponding linear distances were analyzed in a sample of 150 individuals through six supervised machine learning techniques attempting to develop classifiers able to identify elements belonging to the same individual. Furthermore, a 3D analysis was conducted on the articular surfaces through superimpositions of 3D models of corresponding and non‐corresponding crania and atlases obtained by using respectively stereophotogrammetry and laser scanning. This analysis investigated differences in terms of point‐to‐point distances (Root Mean Square, RMS) of superimposed 3D surfaces.ResultsNone of the six machine learning techniques were able to correctly detect a satisfying percentage of correspondent pairs in the overall sample by using the linear variables. The 3D analysis of the articular surfaces found RMS values over 0.53 mm only for superimposed non‐corresponding surfaces, which sets a threshold value to identify 32% of incorrect pairs.DiscussionThe re‐association of cranium to atlas proved to be challenging and hardly possible when considering only metric variables. However, the 3D geometry of the articular surfaces represents a valid variable for this purpose and 3D analyses pave the way for an initial exclusion of incorrect re‐associations, thus should not be considered as a re‐association method per se, but as an exclusionary screening technique.

AbstractObjectivesThis study aimed to characterize mineral nutrition (copper, magnesium, selenium, and zinc) in Samburu pastoralist youth, in the context of differential cultural transitions due to uneven changes in educational access, herding intensity, polygyny, and access to wild, domesticated, and market‐sourced foods.Materials and methodsWhole dried blood spots were collected in a total of 161 youth (highlands,n = 97; lowlands,n = 64) to assess concentrations of cadmium, copper, lead, magnesium, mercury, selenium, and zinc. Concentrations were determined through inductively coupled mass spectrometry. Dietary intakes were assessed by 24‐h recall method and calculation of the probability of inadequate intakes. WHO protocols were applied to collect anthropometric measures in the youth.ResultsNearly half of the adolescents (47.8%) fell below the reference range for zinc status, and 88.2% had low zinc‐to‐copper ratios. High probability of nutrient inadequacies was evident for protein, fat, vitamins A, B12, C, and E. In generalized linear modeling, lowland residence was negatively associated with zinc status and the zinc‐to‐copper ratio, and positively correlated with selenium and copper status. Other significant correlates were dairy livestock ownership; wife number of the youth's mother; meat consumption; vegetable consumption; protein intake; infectious disease morbidities; BMI; and hemoglobin concentrations.DiscussionIn recent decades, Samburu pastoralists of northern Kenya have experienced marked dietary changes in the context of market integration, extreme drought, diminishing pasture availability, and violent civil conflict. Some children (particularly boys) successfully supplement their diets by foraging for wild foods, while others (particularly actively herding girls) may be more vulnerable.

Published: November 2021

AbstractThe terpolymerization of a non‐polar olefin (such as ethylene) and two different polar functional olefins in a controlled fashion is of great interest and importance but has hardly been explored to date. We report for the first time the terpolymerization of ethylene (E) and two different methoxyaryl‐substituted propylenes (AR1P=hexylanisyl propylene; AR2P=methoxynaphthyl propylene or methoxypyrenyl propylene) by a half‐sandwich scandium catalyst. The terpolymerization took place in a sequence‐controlled fashion, affording unique multi‐block copolymers composed of two different ethylene‐alt‐methoxyarylpropylene sequences E‐alt‐AR1P (soft segments) and E‐alt‐AR2P (hard segments) and relatively short ethylene–ethylene (EE) blocks (crystalline segments). The terpolymers exhibited excellent elasticity and unprecedented self‐healing as a result of microphase separation of nanodomains of the crystalline EE segments and the hard amorphous E‐alt‐AR2P segments from a very flexible E‐alt‐AR1P matrix, demonstrating unique synergy of the three different components.

Published: November 2021

AbstractConventional polymerization for the synthesis of carbon nitride usually generates amorphous heptazine‐based melon with an abundance of undesired structural defects, which function as charge carrier recombination centers to decrease the photocatalytic efficiency. Herein, a fully condensed poly (triazine imide) crystal with extended π‐conjugation and deficient structure defects was obtained by conducting the polycondensation in a mild molten salt of LiCl/NaCl. The melting point of the binary LiCl/NaCl system is around 550 °C, which substantially restrain the depolymerization of triazine units and extend the π‐conjugation. The optimized polymeric carbon nitride crystal exhibits a high apparent quantum efficiency of 12 % (λ=365 nm) for hydrogen production by one‐step excitation overall water splitting, owing to the efficient exciton dissociation and the subsequent fast transfer of charge carriers.
