    The study aims to comprehend the adolescents’ behavioral issues and their impact on their physical and emotional life. The theory of socialized anxiety and adolescents has been applied to this study which conceptually analyzes the anxiety and behavioral issues of the students. The qualitative and quantitative approach was utilized in the study and adolescent students were the targeted sample. However, for qualitative study, the teachers and parents of the adolescents were also selected for focus group discussions. The study finds that the mood of adolescents frequently changes even in the school environment. It was also found that adolescents do not share their emotions and problems with their parents, though they prefer their teachers and friends. The study recommends that the gap between the parents and the adolescents must be reduced so that the adolescents could perform more effectively and efficiently in the school environment and their social life

    This paper aims at analyzing the traditional processes of conflict resolution in Pukhtoon society. The institution under study is Jirga an essential element of Pukhtunwali. By using Karak district in Khyber Pakhtunkhwa as a case study, this paper explores Maraka a form of Jirga that dispenses justice at a local level on the basis of Pukhtunwali and Shariah. This study found that the current conflict in the region has significant implications for the institution of Maraka in terms of its structure, composition and dispensation of justice. In most of the Jirgas Ulama (religious clerics) are considered to be an essential part of it. The inclusion of Ulama is making this institution vulnerable to shariatization. A significant number of decisions are taking place on the basis of locally interpreted Shariah law. The paper argues that this trend of shariatization of this institution leads to the weakening of the social relations in the area

    Cement and concrete composites are inherently brittle and exhibit very less tensile/flexural strength capacity as compared to their compressive strength. Use of thoroughly dispersed carbon nanotubes in the concrete matrix is one of the possible solution for enhancing mechanical properties in tension/flexure. In the present research work, small fractions of multiwall carbon nanotube (MWCNTs) i.e. 0.05 and 0.10 wt% of cement have been integrated into the cement concrete to study their effect on the mechanical properties of the resultant concrete mixtures. The enhanced performance of the whole mix lies on a single point that MWCNTs must be thoroughly disperse in the mixture. Hence, special arrangement through usage of high energy sonication along with amended acrylic based polymer (performing as a surfactant) was made to have a uniform dispersion of MWCNTs in the concrete mix. The testing of concrete samples includes i.e., flexure, splitting tensile and compressive strengths after 3, 7, 28 and 56 days of curing. After having comparison with the control mix cured for 28 days, it was observed that the addition of 0.05 wt% MWCNTs increased the splitting tensile strength by 20.58%, flexural strength by 26.29% and compressive strength by 15.60%. Through above results, which verify the increase in concrete mix strength after adding MWCNTs, these MWCNTs may be incorporated in the treatment of Nano/micro cracks completed through process of connecting, branching and pinning. Similarly, as proved in threepoint bending tests, MWCNTs also enhances the breaking strains as well as the fracture energy of the concrete mixes, besides, imparting increase to the strength. The investigations have shown that incorporating lesser amounts of MWCNTs i.e., 0.05 and 0.10 wt% of cement to the concrete mixes after insuring there complete dispersion, unusually improve their properties like mechanical strengths and fracture behavio

    Detecting lung diseases in medical images can be quite challenging for radiologists. In some cases, even experienced experts may struggle with accurately diagnosing chest diseases, leading to potential inaccuracies due to complex or unseen biomarkers. This review paper delves into various datasets and machine learning techniques employed in recent research for lung disease classification, focusing on pneumonia analysis using chest X-ray images. We explore conventional machine learning methods, pretrained deep learning models, customized convolutional neural networks (CNNs), and ensemble methods. A comprehensive comparison of different classification approaches is presented, encompassing data acquisition, preprocessing, feature extraction, and classification using machine vision, machine and deep learning, and explainable-AI (XAI). Our analysis highlights the superior performance of transfer learning-based methods using CNNs and ensemble models/features for lung disease classification. In addition, our comprehensive review offers insights for researchers in other medical domains too who utilize radiological images. By providing a thorough overview of various techniques, our work enables the establishment of effective strategies and identification of suitable methods for a wide range of challenges. Currently, beyond traditional evaluation metrics, researchers emphasize the importance of XAI techniques in machine and deep learning models and their applications in classification tasks. This incorporation helps in gaining a deeper understanding of their decision-making processes, leading to improved trust, transparency, and overall clinical decision-making. Our comprehensive review serves as a valuable resource for researchers and practitioners seeking not only to advance the field of lung disease detection using machine learning and XAI but also from other diverse domains

    No full text
    With the concept of language variation, it has become utmost important to analyze linguistic patterns across register. Pakistani academic writing like other registers in Pakistan is an area that still seeks the attention of the researchers and linguists. This target register needs to be fully described in terms of linguistic characteristics to strengthen the distinct identity of Pakistani academic writing as a register. The present research strives to explore linguistic variation across research sections of Pakistani academic writing as a register along with five new textual dimensions explored through the technique of Multidimensional analysis (Azher &amp; Mehmood, 2016). The research is based on the corpus of 235 M. Phil and PhD research dissertations taken from different universities all over Pakistan. The corpus was further divided into five research sections and was tagged for 189 linguistic features. The ANOVA results on variation among research sections indicate that there lie statistically significant differences among research sections of Pakistani Academic Writing on all the new textual dimensions.</jats:p

    Introduction: Educational institutions have recognised the importance of evaluating academic curricula to keep up with dynamic changes in the field of medical education. The college of medicine at King Khalid University has acknowledged this trend and embarked on reviewing its curriculum. Objectives: To evaluate the undergraduate medical curriculum using SPICES model of curriculum evaluation as a tool with the view to plan and shape future curriculum reforms at the college of medicine, King Khalid University. Methodology: A questionnaire-based survey was conducted eliciting the responses of faculty members and the departmental chairmen regarding the practice of student centred, integrated and non-traditional teaching methods as well as a separate questionnaire for the quality of problem-based learning in practice. The compiled responses from all the respective departments were statistically analysed subsequently. Results: An average of 43.5% of student-centred learning (SCL), 41% of Integrated teaching (IT) and 19% of Non-traditional teaching (NTT) is being employed in different departments of the college of medicine. Conclusion: The results suggest that the college of medicine is currently carrying out traditional teacher centred, discipline based and information-oriented teaching along with small chunks of student centred, integrated and problem-based teaching methods. Although the problem-based learning is proportionately very small in practice but in general, its quality is better in the clinical departments as compared to the basic sciences departments. &nbsp; Key words: Curriculum evaluation, curriculum review, medical education, educational strategie

    Difference equations related to majorization theorems via Montgomery identity and Green’s functions with application to the Shannon entropy

    No full text
    In this paper we give generalized results of a majorization inequality by using extension of the Montgomery identity and newly defined Green’s functions (Mehmood et al. in J. Inequal. Appl. 2017(1):108, 2017). We obtain a generalized majorization theorem for the class of n-convex functions. We use Csiszár f-divergence and generalized majorization-type inequalities to obtain new generalized results. We further discuss our obtained generalized results in terms of the Shannon entropy and the Kullback–Leibler distance. © 2020, The Author(s)

    This paper is devoted to obtain generalized results related to majorization-type inequalities by using well-known Fink’s identity and new types of Green functions, introduced by Mehmood et al. (J. Inequal. Appl. 2017:108, 2017). We give a generalized majorization theorem for the class of n-convex functions. We utilize the Csiszár f-divergence and generalized majorization-type inequalities in providing the corresponding generalizations. As an application, we present the obtained results in terms of Shannon entropy and Kullback–Leibler distance. © 2020, The Author(s)
