    Abstract Purpose—The purpose of this study is to investigate the impact of spiritual leadership on knowledge-hiding behavior in agriculture research institutes of Khyber Pakhtunkhwa, Pakistan. The study aims to analyze theoretical and empirical evidence regarding the mediation pathway, specifically professional commitment, in order to clarify the significant association between spiritual leadership and subordinates’ knowledge-hiding behavior. Design/methodology—This survey-based study used cross-sectional data and a five-point Likert scale to investigate the given hypotheses. In order to address the primacy effect and mitigate any potential for common method bias, data were collected at two distinct time points, with a four-week interval between them. Smart PLS4 was used to assess a sample of 298 complete and valid responses for hypothesis testing. Findings—The results show that spiritual leadership has a negative impact on employees’ knowledge-hiding behavior. Additionally, this relationship is mediated by professional commitment. Originality/value—First, in contrast to the majority of previous studies, which focused on the factors influencing knowledge sharing, the present study investigates the influence of spiritual leadership on employees’ knowledge-hiding behaviors, which are two contrasting concepts. Secondly, the study empirically examined the mediation effect of professional commitment. These three variables have not previously been studied together.

    Abstract Research is continuously being pursued to treat cancer patients and prevent the disease by developing new medicines. However, experimental drug design and development is a costly, time-consuming, and challenging process. Alternatively, computational and mathematical techniques play an important role in optimally achieving this goal. Among these mathematical techniques, topological indices (TIs) have many applications in the drugs used for the treatment of breast cancer. TIs can be utilized to forecast the effectiveness of drugs by providing molecular structure information and related properties of the drugs. In addition, these can assist in the design and discovery of new drugs by providing insights into the structure-property/structure-activity relationships. In this article, a Quantitative Structure Property Relationship (QSPR) analysis is carried out using some novel degree-based molecular descriptors and regression models to predict various properties (such as boiling point, melting point, enthalpy, flashpoint, molar refraction, molar volume, and polarizability) of 14 drugs used for the breast cancer treatment. The molecular structures of these drugs are topologically modeled through vertex and edge partitioning techniques of graph theory, and then linear regression models are developed to correlate the computed values with the experimental properties of the drugs to investigate the performance of TIs in predicting these properties. The results confirmed the potential of the considered topological indices as a tool for drug discovery and design in the field of breast cancer treatment.

    Abstract Purpose: The current study focused on exploring the impact of maltreatment of child laborers on their psychosocial health condition from the views of their parents.
    Methods: A total of 100 parents of child laborers were recruited using snowball sampling. The structured questionnaire comprised two validated scales including ISPCAN Child Abuse Screening Tool (ICAST-P), and Paediatric Symptom Checklist (PSC) were used for the survey. Factor analysis and multivariable linear regression analysis were performed to examine the data using SPSS version 26, and Stata version 16.1.
    Results: A three-factor model consisting of internalizing, externalizing, and attention associated psycho-social impairments of child laborers were derived from the 35-item scale of PSC tool and represented a good fit to the data. A mean estimate of maltreatment indicates that a majority of child laborers are maltreated psychologically, followed by physical maltreatment and neglect. The factor analysis resulted that maltreated child laborers are highly prone to exhibit internalized psycho-social difficulties, followed by externalized and attention-associated emotional and behavioral difficulties among child laborers. The regression model further depicts that child laborers, who had been physically and psychologically maltreated, are significantly more likely to be affected by internalized and attention-related psycho-social impairments.
    Conclusions: The study concluded that victimized child laborers exhibited significant internalized, as well as attention-related problems. These findings may be useful for future studies that examine emotional and behavioral problems among maltreated child laborers and, therefore, for developing prevention strategies.

    Abstract Quantitative structure-activity relationship (QSAR) represents quantitative correlation of biological structural features (called as topological indices) and pharmacological activity as response endpoints. Topological index is a molecular descriptor extensively used to study QSAR of pharmaceutical to assess their molecular characteristics by numerical computation. Meanwhile, the topological indices are numerical functions which are used to predict the growth rate of microorganisms in biological networks. Theoretical assessment of microorganism, such as bacteria and viruses help to expedite the vaccine design and discovery process by rationalizing the lead identification, lead optimization and understanding their mechanism of actions. Hypertree, a network structure derived from graph theory, has a great importance in biological networks for growth of microorganisms, such as bacteria and viruses. In this article, some novel eccentric and degree based topological features of two important biological networks (hypertree and its corona product) are obtained on h-level and derived closed formulas for them. Based on the obtained topological features, the biological properties of these networks are investigated.Communicated by Ramaswamy H. Sarma.

    Abstract Bioconjugate networks refer to networks that are formed by connecting different molecules or particles (such as proteins, enzymes, or nanoparticles) through covalent or non-covalent interactions. These networks are often used in various biological and biomedical applications, such as drug delivery, biosensors, and tissue engineering. The specific properties and behavior of these networks depend on the types of molecules used and the nature of their interactions, which can be studied using various computational and experimental techniques. Farnesyl and geranyl groups are types of isoprenoid chains that are commonly found in various biological molecules such as proteins, lipids, and pigments. The addition of these groups to penicillin molecules may alter their physical and chemical properties, such as solubility, stability, and bioavailability. To gain a better understanding of the structure-property relationships of these antibiotics, this study computes various irregularity indices such as the Albertson index, irregularity index, total irregularity index, Randić irregularity index, and other degree-based indices for two types of sensitive bonds of bioconjugate networks. Numerical results and graphical representations are used to illustrate these findings. The obtained results provide valuable insights into the structure-property relationships of penicillins, which will aid in a better understanding of their behavior and developing more effective antibiotics.

    Abstract Dendrimers, also known as dendritic polymers, have various applications due to their unique properties, such as their monodisperse structure and their ability to be synthesized with precise control over their size, shape, and surface functionality. Dendrimers are used in drug delivery systems to improve drug solubility, bioavailability, and targeting. They can carry drugs to specific sites, such as cancer cells, and release them in a controlled manner, reducing side effects. Dendrimers can be used as gene delivery vehicles to deliver genetic material to cells in a controlled and targeted manner. Mathematical chemistry is useful to model chemical reactions and predict the behavior of chemical systems. It provides a quantitative understanding of chemical phenomena, which can aid in the design of new molecules and materials. It is used to develop molecular descriptors, which are mathematical representations of molecular structures that can be used to quantify the properties of molecules. These descriptors can be useful in structure-activity relationship studies to predict the biological activity of compounds. The topological descriptors are parameters of any molecular structure that gives a mathematical formula to model such molecular structures. In the current study, our concern is to calculate some useful topological indices for three kinds of dendrimer networks and derive closed mathematical formulas for them. The comparisons of these calculated topological indices are also investigated. Our obtained results will be helpful in investigating QSPRs/QSARs of such molecules in many fields of science, such as chemistry, physics and biochemistry. The dendrimer structure (left). From first (G0) to third (G3) generation, the dendrimer's increasing generations are shown schematically (right).
