Calendar Anomalies in Stock Market: A Case of KSE 100 Index

This paper aims to investigate the calendar anomalies in Karachi Stock exchange by using KSE 100 index during the period of 2008 to 2012. The study examined the existence of week days, weekend and monthly seasonal anomalies. These calendar effects are examined by applying different statistical techniques. First of all series of daily and monthly returns were calculated. Then mean and standard deviation of daily and monthly returns were calculated. The values of mean and standard deviation have rejected the first two null hypothesis and accepted the third one. The results provide an evidence for the existence of calendar anomalies at KSE 100 index. The results showed that there is significant difference among the returns of days of the week, and Friday has highest mean average return which makes it confirm that weekend effect exists at KSE. Finally monthly anomaly in stock returns is also present because there is highest positive return in the month of March.     Keywords. Stock Market, Anomalies, weekday effect, weekend effect, monthly effect, Return

Undergraduate clerkship in emergency medicine: experience from Pakistan.

Although Emergency Medicine (EM) is an integral part of undergraduate medical curriculum in many countries, it has not been included formally in the MBBS curriculum in Pakistan. Medical graduates are supposed to be able to handle common as well as life threatening emergencies but little has been done to ensure the process to achieve this competence. The development of an undergraduate EM curriculum is important but challenging task. Implementation of standard curriculum will ensure that medical graduates have gained competence in assessing and managing acutely ill patients and dealing with common emergencies. This paper shares the features of an undergraduate EM clerkship which can be used as a template by other medical institutions

ECONOMETRIC IMPACT OF GOVERNANCE AND TRADE LIBERALIZATION ON POVERTY: A CASE STUDY

Both reformed governance and trade liberalizationreduces poverty while instability of foreign exchange and theinflation rate causes increase in the poverty. In this study, weexamined governance and liberalisation's effect on povertyalleviation by using Time Series data. We applied Auto RegressiveDistributive Lag (ARDL) technique to conclude the empiricalresults. The econometric study revealed a statistically significantand negative effect of governance and trade liberalization onpoverty alleviation. This study will assist the government to makecomprehensive policies for poverty alleviation, especially forPakistan

Understanding Labor Problems and the Social Consequences of Child Labor in Pakistan

Pakistan during the past nearly five decades has experienced various economic hardships and the consequent social complexities. The rapidly and constantly rising population of Pakistan together with the low rate of literacy has given rise to unemployment. Despite introduction of labor policies, the conditions of labor are far from being termed as satisfactory. The impact of labor policies and their non-implementation in true sense has developed serious socio-economic issues in Pakistan. Child labor is one of those grave issues that need serious attention not only by the government but also by the people themselves. Low rate of literacy does play significant role in this issue. This paper discusses the concern of child labor, which in the present era has emerged as a serious human rights issue, with focus on the influence of labor policies of Pakistan on child labor. Keywords: labor, child labor, socio-economic conditions DOI: 10.7176/PPAR/9-3-15 Publication date:March 31st 201

Workplace Internet Leisure and Employee Productivity: Mediating Role of Employee Engagement

There is an ongoing discussion on the role of workplace internet leisure (WIL) and whether it is a vice or virtue. Considering this, Current study is aimed to examine the effects of Workplace internet leisure on employee productivity with mediating role of employee engagement in the Army health care sector of Pakistan. The data was collected through self-administered questionnaires from Armed forces nursing officers of different Army hospitals and institutes through convenience sampling size of 300.SPSS model macro Version 3 (Hayes, 2018) was used to analyze the respondents’ feedback. For analysis of workplace internet leisure influence on employee engagement regression is calculated and results indicates that workplace internet leisure has positive and significance impact on employee engagement, while work place internet leisure has positive but insignificance impacts on employee productivity. Additionally, indirect analysis is calculated for mediation analysis, results indicate that employee engagement positively mediates association between workplace internet leisure and employees productivity. Keywords: Workplace internet leisure (WIL), Employee productivity (EP), Employee engagement (EE), Self-determination theory(SDT), Job demand-resource model (JDR

Polymorphic noncoding region of GNRH1 gene in male patients with impaired fertility

Impaired male fertility is a multifactorial pathological condition and genetic contribution is up to 20%. Gonadotropin Releasing Hormone 1 (GNRH1) is associated with maturation of spermatozoa. We aimed to study genetic sequence of GNRH1 gene in azoospermia males. We collected 50 clinically diagnosed infertile males after the informed consent. DNA was extracted and primers were designed to amplify the exonic and exon/intron boundaries of exon 1 and exon 2 region of GNRH1 gene. The amplicons were sequenced and analyzed using bioninformatic tools. We have identified sequence variations at c.1325-131del.A, c.1325+40 T>G, c.1325+34T>G, c.1325+124 Ins. A, c.1325+126 Ins. A, c.1325+181T>G, c.1325+264 Ins.G and c.1325+269 Ins. A positions. Human Splicing Finder predicted that c.1325-131del.A, c.1325+34T>G, c.1325+124 Ins. A, c.1325+264 Ins.G and c.1325+269 Ins. A have impact on the splicing while c.1325+40 T>G, c.1325+126 Ins. A and c.1325+181T>G have relation with the splicing. The c.1325+40 reported in literature as rs2709608 but has no association with the male infertility. The c.1325+181T>G We could not find other variations in the literature therefore suggested to be novel. Our study suggests that intronic region of GNRH1 gene a highly variable in Pakistani infertile male patients and suggests to explore its correlation with the disease on a large scale

Enhanced electrocatalytic performance of cobalt oxide nanocubes incorporating reduced graphene oxide as a modified platinum electrode for methanol oxidation

Herein, we report a facile hydrothermal method for the preparation of cobalt oxide nanocubes incorporating reduced graphene oxide (rGO–Co3O4 nanocubes) for electrocatalytic oxidation of methanol. The synthesized rGO–Co3O4 nanocubes were characterized using transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), and Raman techniques. The electrochemical behavior of an rGO–Co3O4 nanocube modified electrode was studied using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) techniques. The electrocatalytic performances of rGO–Co3O4 nanocube-modified electrodes with different wt% of GO were investigated in relation to methanol oxidation in an alkaline medium. The rGO–Co3O4 nanocube modified electrode showed enhanced current density due to oxidation of methanol when compared to the bare Pt, rGO, and Co3O4 nanocube modified electrodes. The optimal GO content for an rGO–Co3O4 nanocube-modified electrode to achieve a high electrocatalytic oxidation of methanol was 2 wt%, and it showed an anodic peak current density of 362 μA cm−2
