Methodology: Facebook has become an essential part of nearly every individual's daily life. Though it is beneficial for students in terms of connectivity such as exchanging information, socialization, and other constructive activities, the literature shows that Facebook has become dangerously addictive, causing disruption in routinely activities and academic goals of students. Papers were retrieved from academic databases and Google from 2011 to 2017. All studies that were included appraised critically by using Mixed Method Appraisal Tool. The results showed that both positive and negative impacts of using Facebook on the academic performance of university students. Findings: The results showed that both positive and negative impacts of using Facebook on the academic performance of university students. Conclusion: The conclusions propose that, despite the variance of findings, the overall outcome is negative when it comes to the use of Facebook in academic performance. Furthermore, it highlights the ways that how Facebook can help to enhance the academic performance of university students.

The aim of the study is to find a correlation between organizational justice and readiness to change. The sample was carried from the employees working in telecom sector. The sample was carried from 309 employees. Previously used scales for the measurement of variables was carried out. The results of linear regression predicted that some factors of organizational justice are strong predictor of readiness to change.

This study, therefore, sought to examine the effect of employee job satisfaction on employee's happiness at work among telecommunication workers in Pakistan. The study was anchored on the motivation theory and includes some factors that influence motivation at the work place. The motivational factors include job inspiration, job security, benefits/salary, work environment and leadership. These motivational factors are expected to influence the dependent variable (happiness at work) through a mediating variable (employee job satisfaction). Employee job satisfaction functioning as an independent variable is also expected to influence the exogenous variable (happiness at work). Data for the study was obtained from a sample of 515 telecoms workers from Pakistan using a structured questionnaire. The data was analyzed through Structural Equation Modeling via SPSS 22 and SmartPLS 3.0. Findings from this study indicate factors that determine or influence employees' job satisfaction are job inspiration, benefits, job security, and leadership in that order. The study further found a positive and significant relationship between the independent variables (job inspiration and benefits) and employee job satisfaction. Also, the study found that employee job satisfaction has a positive and significant influence on happiness at work. The study builds on the empirical findings on factors influencing employee job satisfaction by linking it with happiness at work in the telecoms sector This study contributes to the extant literature on happiness at work and makes valuable contribution to future research in this area.

The rationale behind the study is to find out whether the daily exposure of the students to social networking sites has effect on their academic performance. The researcher tries to find out the answers of research questions. 1. Most used social networking sites by students and purpose of using social networking sites, 2. How much time students spend on their study? 3. How much time students spend on social networking sites? The research study also tests a hypothesis that social networking sites usage has significant impact on academic performance of students. Methodology: Researcher uses a quantitative study design to conduct the research. A sample comprises of hundred students has been selected by means of convenience sampling from a private sector university of Karachi to study the phenomenon. Data has been collected through a detailed structured questionnaire and analyze by using Statistical Packages for Social Sciences (SPSS V 17.0). Findings: Findings also show that exposure to social media has effect on the students as they found to be more engaged in social networking instead of spending time on studies. Conclusion: This paper recommends that student should pay more attention to studies, limit their use of social networking and use it more for educational purpose.

Here, absorption against non-flat distributions is examined. These non-flat distributions are Gaussian and Lorentz distribution. Analytically equivalent widths for absorption against non-flat continuum are complicated integrals. It is impossible to solve these integrals analytically so I have solved them numerically. At low μ the absorption is independent on profile while the growth of absorption depends on profile at high μ, where μ is width.

The quantitative and inductive approach was used to collect data for 515 employees. The data was collected through a field survey with a closed-ended questionnaire methodology. The Smart-Partial Least Square (PLS-3.0) was used to analyze structural equation modeling (SEM) for studied variables. Furthermore, findings proved that there is a positive relationship between benefits and salary with employee job satisfaction. The work environment mediates the relationship between Benefits & salary and employee job satisfaction. Here, leadership moderates between work environment and employees' job satisfaction. The job stress has a relationship between employee job satisfaction, whereas, the work environment has a positive effect on job stress. This study assists the executive bodies of the telecommunication sector, how to reduce job stress and raise the level of job satisfaction among employees.

Expressing the energy of a surface in terms of its local deformation, local force on the surface is given by differentiating the energy with respect to position that gives an equation. The modelled equations make a system that has been converted in to a biquadratic function and used to minimize the energy to save the life of spring in the best method of optimization. The Powell's method is given in detail and compared with Downhill Simplex method.

The results of three stages regression supported the authors proposed hypothesis that those employees who value teamwork in organization are less affected by organizational politics in term of job satisfaction and particularly, affective organizational commitment in contrary, to others who give little value to expression of teamwork. Therefore, based on statistically significant, interaction of teamwork and organizational politics in proposed model, it is infer that the potential adverse consequences of organizational politics can be mitigated through promoting importance of teamwork within organization.
