2-D Seismic Data Interpretation of Qadirpur Area, Pakistan Ammad Ali Tariq Aim of the study is to interpret 2D-Seismic Reflection time section of the Qadirpur Area (Sindh Province) Pakistan. This seismic section is a Pre-stacked time migrated section and was provided by the Department of Earth Sciences, Bahria University Islamabad and this line bears the title 985-QPR-03 It is about 40 Kms in length and is oriented in SW-NE direction. OGDC acquired data in October 1998 and processed it in January 1999. The velocity information is in the form of RMS. DIX interval and DIX average at different times is given, and is provided at selected S.P. RMS velocity varies from 1500 m/s to 5000 m/s Interpreted part of this line from S.P. # 460 to S.P # 720, with CDPs from 920 to 1440 Length of this part of seismic section is 13 Kms. For interpretation of this part of Seismic section, four reflectors and 2 faults are marked on the basis of prominent reflections from subsurface horizons due to changes in lithology and diffractions. Using the RMS velocity given in the velocity panels on seismic section for selected shot points, calculate the time on constant velocity interval of 100m/sec Then using these calculated time and velocity values prepare the Iso-velocity graph and Iso-time graph (for mean line method) by taking constant velocity and time respectively, In Mean line Method of velocity estimation, a velocity vs time graph is prepared. From this graph, a mean average velocity is determined. From Seismic Section, arrival times (two ways) of each marked reflector are determined, Using these arrival times, Time Section is prepared. Also using these arrival times, calculate the average velocity for these times on mean line graph and then the depth of each reflector has been calculated using s(vt)/2 and is represented in Depth Section. Depth Section provides a reliable picture of reflectors and structures present in the subsurface of the area. Well correlation is also done, which satisfy the calculated depths, so horizons have been marked Interpretation of the Project Area shows that, extensional regime and calm environment prevails in the area. Reflectors are almost flat-lying, whereas Horst and Graben structures have been found. Supervised by Mr. Rashid Jamil

IMPACT OF PERFORMANCE APPRAISAL SYSTEM ON EMPLOYEE SATISFACTION AT KARACHI PORT TRUST MAHWASH MERAJ, Reg # 30563 Purpose: The puipose of this research was to find out the impact of Performance Appraisal System (PAS) on Employee satisfaction at Karachi Port Trust (KPT). Performance appraisal is considei ed an essential tool to motivate and develop employees. Effort was made to find out the effectiveness of PAS by looking at its various aspects. Methodology/sample: The research, being explanatory in nature, involved quantitative data collected through a questionnaire. The data were collect from a sample of 50 managerial level employees belonging to different departments of KPT. To analyze the data, Regression and Correlation tests were applied. Findings: The investigation and analysis results have revealed that there is no participative goal setting at KPT. Managers do not give an opportunity of participative goal setting to employees, although it is a very essential component of PAS. However, periodic review meetings during the appraisal cycle are a source of satisfaction among the employees as they are provided feedback for corrective measures. Practical Implications: The findings/results of this research are likely to help the management of KPT about effectiveness of PAS and also about its weaknesses. Participative goal setting can improve the satisfaction and motivation level of employees. Although managers set goals in the start of the year but for perfect PAS, participation of employees and provision of timely feedback is essential. Other organization may also benefit from this study. Future scholars may further study causes of non-participative management by the manageis. Supervised By Dr. Rafique Ahmed Khan

IMPACT OF 'LEAD-TIME, ON-TIME DELIVERY & PERCEIVED SECURITY RISK' ON CUSTOMER RETENTION IN E-COMMERCE INDUSTRY OF PAKISTAN Shaukat, Naeem Reg # 28792 Purpose of Research: The purpose of this research was to find out the Impact of Lead Time, On-Time Delivery & Perceived Security Risk on Customer Retention in E-Commerce Industry of Pakistan. It is believed that there is a lack of customer retention rate in E-Commerce industry of Pakistan. Customers prefer to purchase from retail markets rather than from online stores. Methodology of Research: This study is descriptive in nature. Which involves quantifiable data which was gathered through a survey questionnaire. The data was collected from a sample population of 164- customers, who had experienced Online shopping in Pakistan. In order to analyze the data regression and correlation test were performed via SPSS. In this research Non- probability and convenient selection approach was used. As Dornyei (2007) stated that convenience sampling method is a type of non-probability or non-random sampling technique. Because in this technique individuals from targeted population are selected on certain definite standards. Like Geographical Location, Easy Access, Timely availability, & willingness to participate. Findings of Research: The results of this study confirm that there is significant impact of Lead-Time, On-Time Delivery, and Perceived Security Risk on Customer Retention in E-Commerce industry of Pakistan. All three components or independent variables of this study are observed useful and showed a significant impact with a significance value less than 0.05, on dependent variable which is Customer Retention. Practical Implications: The findings resulting from this research will help the investors and government of Pakistan to implement effective policies and eliminate those causes which are resulting a decreasing trend of Customer satisfaction and retention in this Online industry.
