Medico-Legal Cases (MLC) Presented at a Tertiary Care Center and Acute Symptoms of Post-Traumatic Stress Disorder among the Survivors

Objectives:  An observational, prospective study was conducted to determine the incidence and risk factors associated with victims of physical assault and symptoms of post-traumatic stress disorder (PTSD). Material & Methods:  All the registered medico-legal cases reported to the emergency department of Gambat hospital were included in the study. The data was collected on a predefined questionnaire including age, gender, mode of injury, weapon of the injury, type of assault (blunt or penetrating), firearm injuries, and road traffic accidents from medico-legal registers. Impact of Event Scale (IES) was used to assess Post-traumatic stress disorder. Results:  The mean age (SD) of victims was 29.3 (10.25) years. Blunt injuries were experienced by 47 (31.33%) victims. The majority of the victims suffered road traffic collision injuries, 59 (39.33%). Forty-eight (32%) victims had substantially higher IES scores (above 37) that confirmed severe PTSD that may contribute to the suppression of the immune system’s functioning among survivors. The majority of the victims were between 18 and 40 years. Conclusion:  The most common cases were related to road traffic collisions followed by blunt injuries. The incidence rate of PTSD was also prevalent in these individuals. Thus, strategies should be developed to prevent such incidents and those who suffer from such traumatic events must be offered psychiatric consultation

The Role of Radiology (X-Ray versus Computed Tomography) in Medicolegal Cases Presented at a Tertiary Care Hospital in Pakistan

Objectives:  A prospective observational study was aimed to assess the role of plain radiographs and computed tomography in detecting head injuries presented at the medicolegal office at the Forensics and Radiology Departments, Gambat Medical Hospital, Sindh. Material and Methods:  All cases referred from the Medicolegal Office (MLO) with head injury were included. All victims underwent X-ray head and computed tomography skull was done with 1 or 1.5 cm thick axial sections without administration of intravenous contrast. The radiological reports of X-ray head and CT scans were documented and comparatively evaluated. Results:  Mean age was 38.63 ± 3.91 years. In 51 (45.13%) cases, X-ray was able to detect skull fracture, while CT scan detected 64(56.64%) skull fractures. There were 54 (84.3%) true positives, 3 (2.6%) false positives, 10(8.8%) false negatives, and 40 (40.7%) true negatives. The accuracy of X-ray to detect skull fracture was 88.50%. Conclusion:  X-ray had a sensitivity and specificity of 84.38% and 93.88%, respectively. It is a reliable tool to detect skull fractures in victims of assault in comparison with CT scans. X-ray is also associated with low dose radiation exposure as compared with CT scan which delivers 70 times more exposure than the former

Supramolecular interaction of non-racemic benzimidazolium based ion pairs with chiral substrates

A series of novel benzimidazolium-based non-racemic ionic liquids (ILs) was synthesized from low–cost chiral terpenoid alcohols and fully characterized by the use of a wide variety of techniques, such as DSC, ESI-MS, ATR FT-IR, polarimetry as well as 1H and 13C NMR spectroscopy. The ILs were investigated as chiral shift agents for the chiral recognition of racemic mixtures of Mosher’s acid potassium salt by 19F NMR spectroscopy, leading to high splitting values of the CF3 signal. Supramolecular interactions between salt and H–C2 of chiral benzimidazolium cation are responsible for the chiral recognition, as was demonstrated by experimental evidences. Indeed, the enantiomeric excess value of enantioenriched substrates depends mainly on the strength of the contact ion pairs

Towards a model of mathematics attitudes formation : through the child’s perception of social agents and self-beliefs

La revue de littérature montre que dans le cadre théorique, le concept d’attitude envers les mathématiques n’a pas été l’objet de suffisamment d'attention. Cette étude propose une vue multidimensionnelle de l'attitude envers les mathématiques basée sur deux composantes: l’intérêt et la croyance. Nous proposons un modèle théorique de formation de l’attitude. Dans ce modèle, nous faisons l’hypothèse que les tendances évaluatives de l’élève de cette discipline (qui deviennent l’attitude) sont le résultat de la connaissance personnelle, construite en conséquence de sa croyance et de ses réactions affectives antérieures dans cette discipline, et se développent sous l’influence de facteurs psychologiques et sociaux. En tout 1499 élèves (678 filles et 821 garçons) de la 6ème et de la 9ème classe dans 10 écoles du Pakistan ont participé à l'enquête finale. Dans cette étude, les filles ont montré une attitude positive en ce qui concerne la «croyance de besoin», alors que les garçons ont montré une attitude positive en termes de «plaisir». Par ailleurs, on a découvert que le bas niveau d’éducation des parents a une influence positive sur la « croyance de besoin » des mathématiques chez les élèves. De plus, l’analyse de notre modèle a montré que l'influence de l’enseignant, plus forte que celle des parents, passant par le concept de soi et l'auto-efficacité en mathématiques des élèves, développe un effet positif sur l’attitude. En outre, dans le cadre de l’attitude, la direction de causalité a été trouvée meilleure de l’intérêt vers la croyance. Cette étude ouvre la porte à revisiter les études sur genre et attitudes en utilisant notre analyse conceptuelle multidimensionnelle.In mathematics education research, less work is documented on theorizing mathematics attitude and its formation process, especially in Pakistani context. Therefore, this study proposed a multi-dimensional concept of mathematics attitude based on two components (mathematics interest & mathematics belief). Further, it was theorized in the model that, the student’s evaluative inclinations about mathematics are the results of his private knowledge, constructed as a consequence of prior beliefs and affective reactions with mathematics, under the influence of psychological and social factors. Total 1499 students (671girls & 821boys) of grade six and nine from ten schools of Pakistan participated in this study. Results indicated that girls possessed significantly more positive “maths need belief”, while boys hold significantly more positive interest in the dimension of “enjoy doing maths”. Regarding parents’ education effect, low level of education caused strong “maths need belief” in students. In the hypothetical model, teacher affect significantly positive the mathematics attitude than parents, mediated through student’s maths self-concept and self-efficacy. Within the components of attitude, causality direction was found better from interest to belief. This research concluded that students’ differences in mathematics attitude are caused by the societal needs and expectations developed by parents and teachers, sometimes accompanied by stereotypic beliefs, which affect a boy and a girl differently. Findings of this study demand a review of already done researches on gender differences in mathematics attitude in the light of dimensional concept, proposed in this research

Corporal Punishment in Schools: A Narrative Analysis of Contemporary Situation

The environment at home, school, social circles, and key life events all have an impact on students’ wellbeing in the formative years. The tremendous familial and societal pressure placed on pupils to be high academic achievers is a prevalent factor in the Pakistan’s context. Scoring marks is the primary goal, particularly in South Asian culture where students’ performance has been reduced down to competitive testing formats. High grades on progress cards have been linked to a better likelihood of gaining admission to prestigious schools, resulting in a promising career and future. Security, family pride, and social position have all been connected to these factors. With this perspective, parents, often impose unrealistic expectations on the child and in schools, teachers deliberately or unintentionally use the corporal punishment to achieve and maintain the discipline and good grades of the students which negatively affect their behaviors and regress them academically (Nair, 2014). This narrative review-based paper explain why teachers are using corporal punishment as the terminal solution for most of the problems despite of legislation against corporal punishment in schools through “Prohibition of corporal punishment Bill, 2014”? This paper concluded that teachers are unable to abide this law effectively due to their personality traits tagged with their own aggressive childhood experiences. Therefore, it was suggested that in order to eradicate the corporal punishment from schools, teachers’ psychological well-being assessments and their counseling may be way forward to achieve the students’ well-being

Mediating Role of Affective Organizational Commitment on the Relationship between Training and Employee’s Performance: a Case of Civil Society Organizations

In a competitive business environment, organizational performance depends upon employees’ performance and their capabilities which can be enhanced through effectual tools like, training to boost knowledge, behaviour and skills of employees. This research aims to investigate the effect of training on employees’ performance directly and indirectly mediated through affective organizational commitment in the civil society organizations of Pakistan. Convenient sampling technique was used and the sample of 219 employees was selected out of 569 total employees from different CSOs Offices of Punjab by using Krejcie and Morgan table. Descriptive statistics, correlation and confirmatory factor analysis were used to analyse the data. The results demonstrated that training has a positive and significant impact on employees’ performance. Further, an effective organizational commitment was found to have significant mediation in the relationship between employees’ performance and training. Thus, the study suggested that training should be the part of civil society organization to boost the organizational commitment which will affect the employee performance

Training and Employee Performance: Mediating Role of Job Satisfaction in Civil Society Organizations of Pakistan

In the advanced business world, training is an indispensable tool used to build the new abilities, skills and enhance the employee’ knowledge which in result boost the employee performance. The current research aims to investigate how training influences employees’ performance in the presence of job satisfaction as a mediator in civil society organizations of Pakistan. The quantitative survey research design was used. A sample of two hundred and nineteen employees was drawn from civil society organizations of Punjab, using the Krijchi and Morgan Table. A questionnaire was adopted as a tool to collect the data. Hierarchical regression was run to analyze the mediating impact of job satisfaction on the relationship between training and employee performance. The results indicated that training has a direct positive relationship with the performance of the employee. Further, job satisfaction partially mediates the relationship between training and employee performance. It is suggested that need base and interactive trainings should be provided to enhance employee’s performance

Mediating Effect of It Tools Usage on the Relationship Between Academic Self-efficacy, Learning Attitude and Academic Performance

Information technology has a powerful impact on our daily doings in all walks of life. Particularly in educational settings, the pyramid of learning attitude has been altered by the usage of technological tools in learning process and thus the performance of the students. However, comprehensive integration of information technology tools to enhance the learning is a deemed necessity of information age where adolescents are seemed as digital natives. Therefore, this study focused on measuring the mediating effect of information technology usage on the relationship of Academic efficacy &learning attitude and academic performance of the students in secondary schools. Multi stage sampling technique was used; 10% of secondary public schools were randomly selected from four randomly selected Tehsils of Sargodha as sample; at second stage, 20% of the 10th graders were selected from each school through stratified random sampling. Data was collected through questionnaire by using quantitative survey method. Path analysis was applied to study the mediating effect of IT usage on the relationship between academic self-efficacy and academic performance. Findings revealed that academic self-efficacy exert significant positive in direct effect on the academic performance mediated through IT usage. Similarly, academic attitude also found to have significant direct and indirect effect on the academic performance. Therefore, it is suggested that teachers should integrate the technology embedded activities in their teaching

The current study investigates incompressible, MHD flow of Cross nanofluid containing of gyrotactic microorganisms and thermophoretic particle deposition over a sheet with activation energy and variable thermal conductivity. The variable characteristic of thermal conductivity is considered as a linear function of temperature. The present study’s insights can optimize the design of nanofluid-based systems, enhance drug delivery methods, improve environmental monitoring, refine materials engineering, advance microfluidics for diagnostics, boost renewable energy technologies, and upgrade electronics cooling solutions. Moreover, this study contribution to scientific understanding will catalyze further research across disciplines, fostering innovation and progress. Cross nanofluid containing iron oxide ( F e 3 O 4 ) nanoparticles, and based fluid ethylene glycol ( C 2 H 6 O 2 ) is used. In the current study, distributions of concentration, temperature, mass, microorganisms, and flow are examined in the presence of nanofluid while also accounting for thermophoretic particle deposition and a heat source. The proposed flow equations are transmuted into ODEs by employing the suitable similarity variables. RKF-45th approach is used to evaluate the reduced equations. Graphs are used to determine the effects of important factors on thermal, microorganism, concentration, and flow profiles. With a rise in the Marangoni ratio parameter, the velocity distribution is enhanced, whereas the temperature distribution exhibit inverse behavior

Why I don’t Blow the Whistle? Perceived Barriers by the University Teachers to Report Wrong Doings

Whistle blowing is a term used to report the unethical act of colleagues and wrongdoings within the organization. Bringing attention towards the misconducts and organization’s effective response accordingly improves the productivity and quality of services. However, this generates the potential threats of organizational and interpersonal conflicts for the whistle-blower thus leads often failure in reporting by the personals or employees. This study explores the perceived barriers by the university teachers, which may hinder the process of reporting wrongdoings. Social constructionism qualitative research design is used. At first phase, face-to-face interviews of six faculty members and narrative research design has been used. At second phase, three focused group discussion sessions with total 24 participants, were carried out in three public sector universities of Punjab, purposively selected. Analysis shows that the people hesitate to blow the whistle due to psychological, social, and organizational barriers, like, fear of joblessness, security threats, lack of supportive organizational polices, lack of adequate mechanism for blowing the whistle, the personal waded interest of the personals. However, this procedure can be enhanced by addressing the issue well in time, adequate security measures, ensured job security for the whistle-blowers, and adoption of a well-developed reporting mechanism in the universities
