Impact of Devaluation on Trade Balance in Pakistan

The purpose of this paper is to find the impact of devaluation on trade balance in Pakistan in both long and short run using bound testing approach to Cointegration and Error Correction Mechanism (ECM). The result shows that devaluation is effective in improving trade balance and there is a cointegrated relationship between the real effective exchange rate and trade balance in the long run.

The price puzzle and monetary policy transmission mechanism in Pakistan: Structural vector autoregressive approach

This paper address the issue of monetary policy effectiveness and the price puzzle, a positive response of prices to monetary tightening, in Pakistan. Study examines the effects of monetary policy shock on price level and other macroeconomic variables such as output, exchange rate and money supply within the structural VAR framework over the period 1992: M1 to 2010:M08. We find that a contractionary monetary policy shock has a positive effect on prices and the output increase over some horizon following the monetary tightening but continuously falls after initial rise. The results also indicate that monetary contractions in Pakistan over period reviewed associated with persistent depreciation of domestic currency value relative to the U.S. dollar.Monetary policy, Price puzzle, Structural VAR, Pakistan

Moderating effect of social support on personal financial constraints and job stress relationship

The aim of this paper is to examine the moderating effect of social support (which may be supervisory, friends, family and relatives) on the relationship of personal financial constraints and job stress relationship. Sample consists of 294 respondents from randomly selected 28 branches of 22 banks located across all major cities of Pakistan. Moderated regression analysis has been used to test the hypothesized relationships. Personal financial constraints enhance job stress and social support moderates this relationship. Job stress increases when an employee faces financial constraints but decreases in the presence of social support. Practical and theoretical implications are drawn. This research is conducted in banking industry, so its results can’t be generalized to other industries. This paper is the first which examines the impact of a non-work related variable, personal financial constraint on job stress along with buffering role of social support. Its findings have great implications for employers for increasing productivity of employees.Job stress, personal financial constraints, social support, moderating, banking, Pakistan

Maternal education, empowerment, economic status and child polio vaccination uptake in Pakistan: a population based cross sectional study

Objectives: To explore the association of maternal education and empowerment with childhood polio vaccination using nationally representative data of Pakistani mothers in a reproductive age group. Design: Cross-sectional. Setting: Secondary analysis of Pakistan Demographic and Health Survey (PDHS), 2012–2013 data was performed. Participants: Of the 13 558 mothers included in the survey sample, 6982 mothers were able to provide information regarding polio vaccinations. Main outcome measures: Polio vaccination coverage among children aged up to 5 years was categorised as complete vaccination (all four oral polio vaccine (OPV) doses), incomplete vaccination, and no vaccination (zero OPV dose received). Mothers' empowerment status was assessed using standard ‘Measure DHS’ questions regarding their involvement in decision-making related to health, household possessions and visits among family and friends. Education was categorised as no education, primary, secondary and higher education. Results of multinomial regression analyses were reported as adjusted OR with 95% CI. We adjusted for age, wealth index, urban/rural residence, place of delivery, and antenatal and postnatal visits. Results: Only 56.4% (n=3936) of the children received complete polio vaccination. Women with no education had significantly higher odds of their child receiving no polio vaccination (OR 2.34, 95% CI 1.05 to 5.18; p<0.01) and incomplete vaccination (OR 1.40, 95% CI 1.04 to 1.87; p<0.01). Further, unempowered women also had significantly higher odds of not taking their child for any polio vaccination (OR 1.58, 95% CI 1.17 to 2.12; p<0.01) and incomplete vaccination (OR 1.18, 95% CI 1.00 to 1.41; p=0.04). Conclusions: Illiteracy, socioeconomic status and empowerment of women remained significant factors linked to poorer uptake of routine polio vaccination

Factors Affecting job satisfaction of employees in Pakistani banking sector

The job satisfaction has got tremendous attention in organizational research. The focus of this study is to determine the impact of various human resource management practices like job autonomy, team work environment and leadership behavior on job satisfaction. It also investigates the major determinants of job satisfaction in Pakistani banking sector. This study further evaluates the level of difference in job satisfaction among male and female employees. The sample of the study consisted of 450 employees working in different banks of Rawalpindi, Islamabad and Lahore through the questionnaire, of which 295 were returned and processed. SPSS was used to analyze the data, using Independent Sample T Test, Correlation and regression analysis. There is a positive and significant link between job satisfaction and human recourse management practices like team work environment, job autonomy and behavior of leadership. From the findings of the study, it is also inferred that male and female workers have significantly different level of job satisfaction.Human resource management practices, job satisfaction, employees, banking sector

A Quantum Key Distribution Network Through Single Mode Optical Fiber

Quantum key distribution (QKD) has been developed within the last decade that is provably secure against arbitrary computing power, and even against quantum computer attacks. Now there is a strong need of research to exploit this technology in the existing communication networks. In this paper we have presented various experimental results pertaining to QKD like Raw key rate and Quantum bit error rate (QBER). We found these results over 25 km single mode optical fiber. The experimental setup implemented the enhanced version of BB84 QKD protocol. Based upon the results obtained, we have presented a network design which can be implemented for the realization of large scale QKD networks. Furthermore, several new ideas are presented and discussed to integrate the QKD technique in the classical communication networks.Comment: This paper has been submitted to the 2006 International Symposium on Collaborative Technologies and Systems (CTS 2006)May 14-17, 2006, Las Vegas, Nevada, US
