This research aims to check the mediating role of resilience between the relationships of hope with life satisfaction. Hope and mindfulness are independent variables and life satisfaction is the dependent variable. This is cross-sectional research and data was collected from 350 employees of an engineering company randomly. Simple linear and multiple regression analyses are performed for testing the hypotheses of the study. Results indicate that hope has a direct positive impact on life satisfaction and resilience respectively. Moreover, resilience is partially mediating the relationship of hope with life satisfaction. The current study considers only the employees of Mott MacDonald Group. Current research is a case study on Mott MacDonald Group, so cannot generalize the results on other types of industry and describes only a few predictors of life satisfaction. Future researches will also conduct on the same kind of engineering firm for generalization. In future researches, some other variables as predictors and outcomes may also include for explaining the phenomenon of life satisfaction. It is also beneficial to conduct this kind of research on sectors like the textile sector, banking sector, and telecom sector. Life satisfaction is very supportive for the organizations to maintain balance in work and lives of employees which may result in dedicated employees. The proposed research model of life satisfaction is satisfactorily supported by empirical tests.
Objective: To evaluate VMAT plans for conformity and homogeneity of radiation dose to the target in order to share our experience as a pioneering institute to use VMAT technology in Pakistan. Methods: Since December 2014 to January 2018, 530 patients of various anatomical sites were treated by VMAT technique at Neurospinal Cancer Care Institute (NCCI) Karachi Pakistan. ERGO++ planning system (Version 1.7.2) was used to develop VMAT plans with single or multiple arcs by the rotation of couch and gantry. The plans were evaluated by calculating Conformity Index (CI) and Homogeneity Index (HI) and critical organ (OARs) doses of individual tumor sites. Results: The average CI of various sites was 1.4 (range: 1.0–2.0) and average HI of various sites was 1.20 (range: 1.07–1.374), respective critical organ doses were adequately achieved. Conclusions: VMAT treatment planning technique showed good conformal and homogeneous target coverage with sparing of organs at risk and reduced treatment delivery time. With these features, safety of VMAT technique may allow its routine clinical use, though it is still under investigation in many areas.

The purpose of current study is to explore the relationship of organizational commitment, verbal bullying and direct bullying in the banking sector of Lahore. Organizational commitment has been found to a serious problem in these days for all organization. This research concentrated on organizational commitment and two types of bullying i.e., physical and verbal bulling. The banking sector chose to conduct this current study. Because banking sector is considered as one of the extremely stressful sectors in Pakistan and it has great share in the economy. Simple random sampling technique was applied to choose 300 respondents from 28 banks located in Lahore (Pakistan). the structure questionnaire was utilized to gather the data. 270 fully completed questionnaires were used in the final analysis. Multiple linear regression was applied through SPSS to test the hypotheses. Overall workplace bullying has negative influence on organizational commitment. Moreover, two dimensions like the verbal bullying and direct bullying has the negative influence on the organizational commitment.
The aim of current study was to examine how absorptive capacity functions as mediator amid organizational trust and Process innovation. Employee information was gathered and basic linear and multiple regression analysis were used to further examine the data. The findings support hypothesis that organizational trust influences process innovation via absorptive capacity. The conditional indirect impact model demonstrates how absorptive ability mediates indirect link between organizational trust and process innovation. The cross-sectional design of this study was its main drawback. To deepen their understanding of the significance of organizational trust, researchers in human resource management should work to expand and imitate findings using multi-wave data. This is first example to demonstrate how absorptive capacity might affect organizational trust, which in turn can drive process innovation. The study offered significant results that helps in reaching the desired conclusions and offering certain recommendations to policymakers and future researchers in order to revisit their research regarding the issues under consideration.
