Mother Schooling and Malnutrition among Children of Rural-Urban Pakistan

Background: Although many causes of malnutrition are discussed in previous studies, the impact of mother schooling on malnutrition among children of rural-urban Pakistan and mediating factors is not posited in case of Pakistan. Hence, this study examine the effect of mother schooling and intervening linkages on acute and chronic malnutrition. Methods: The prior empirical relationship is examined by calculating adjusted risk-ratio with the help of binary logistic regression analyses using a sample size of 3184 rural-urban mothers retrieved from the latest Pakistan Demographic and Health Survey 2012-13 (PDHS). Results: The urban mothers without education are more likely to have stunted and underweighted infants as compared to rural ones. Rural (urban) mothers with poor (moderate) economic position have more chances of having stunted infants than urban (rural) mothers. However, only urban mothers with poor status have more chances of having underweight kids relative to mothers with rich class. The rural mothers with empowerment and with seeking for medical services are less likelihood to have stunted infants than urban ones. Value of the Study: The impact of mediating factors arising from education on rural infants’ health is higher than that on urban infant

THE CREDIT SUPPLY CHANNEL OF MONETARY POLICY TRANSMISSION MECHANISM: AN EMPIRICAL INVESTIGATION OF ISLAMIC BANKS IN PAKISTAN VERSUS MALAYSIA

The transmission mechanism of monetary policy is explained through the relationships between a change in money supply and the level of real income. Monetary policy transmits to the real sector through several different channels. Such channels include the interest rate channel, the exchange rate channel, the asset-pricing channel, the credit supply channel, and the bank balance sheet channel. This paper empirically investigates the credit supply channel of monetary policy and explores the differential impact of monetary policy on credit supply of Islamic banks in Pakistan versus Malaysia. The robust two-step System-Generalize Method of Moments (GMM) estimator is applied on an unbalanced panel dataset over the period 2005-2016. While estimating the effects of three alternative measures of monetary policy on banks’ credit supply, several bank- specific variables are included in the specification as control variables. We provide strong evidence on the existence of credit supply channel in the baseline models for both countries and differential impact of monetary policy through Islamic banks in Pakistan versus Malaysia in the extended models. Our findings suggest that there is a vital need to consider the nature of Islamic banks while devising the instruments of an effective monetary policy in countries with dual banking system like Pakistan, Malaysia, Indonesia, Bahrain, Saudi Arabia, Qatar and others

Evaluation of Prognostic response in HIV positive patients after Antiretroviral Therapy

Objective: The present study was aimed to monitor the prognostic response of antiretroviral therapy in HIV positive patients. Methodology: The study was conducted on confirmed HIV positive patients registered at HIV treatment and care centre, PIMS. Islamabad from January 2013 to December 2015.. Among all HIV positive patients,276 adult cases were selected. There were 263 patients on first-line antiretroviral (ARV) therapy and 13 patients were shifted to 2nd line ARV therapy.CD4 cell counts and viral load (Polymerase chain reaction) monitoring was done after one year of starting ARV therapy. Results: Out of 276 adult patients,  75%(n=207) were male and 25%(n=69) were females. Among 276 adult cases, 95.3% (n=263) patients were on first line ARV therapy. Patients on first line ARV therapy showed good prognostic response. There  were 15.5%(n=40) patients having  CD4+cells less than 350cells/µL. There were 84.5%(n=223) patients having  CD4 +cells count greater than 350cells/µL There were 69%(n=182) patients having viral load <50copies/ml and 31%(n=81) patients who had viral load >50copies/ml. Conclusion: First line ARV therapy given to HIV positive patients proved itself best both in respect of increasing the immunity of HIV positive patients by increasing the number of CD4 cells and also results in effective viral load suppression

Towards the Implementation of Monetary Management in Islamic Economic System Based on Recent Developments

Monetary management is an essential part of the objectives of Shari’ah under the umbrella of the preservation of wealth (Ma’al). Our primary sources: Qur’an and Sunn’ah, provide divine legislation on the prohibition of Riba to manage bases of monetary transaction. Further, the juristic tools facilitate scholars to propose solutions to meet the emerging issues on diversified aspects of society. Muslim scholars have always adapted and contributed to the Islamic finance system and regulation, theoretically and practically. In recent decades, Islamic banking and finance has seen strong momentum with double digit growth, fulfilling the monetary requirement of depositors on the liability side along with industry on the asset side. We seek to review the theoretical and empirical literature on Islamic monetary mangement. Monetary management in the Islamic economic context is still an area that needs more research. This paper examines how literature has been developed over time up until modern Islamic economic and banking practices. The findings suggest that Islamic monetary management has been gradually developed in recent years and such development is remarkable steps forward in pursuing Islamic monetary policy independently. In addition, Islamic monetary policy is proved to be relatively more effective compared to interest based conventional monetary policy. The implications of such findings have established new milestones for the central banks of all the countries, including the muslim majority countries for pursuing interest free Islamic monetary policy with full confidence.  Furthermore, there are four major views on Islamic monetary policy and the central banks of the world should choose one of the best methods and views for the greater effectiveness of monetary policy because conventional monetary policy has been less effective in bringing full employment and price stability in recent years and financial crisis has crippled the interest based conventional economic systems quite badly

Cytotoxic and antioxidant potentials of ellagic acid derivatives from Conocarpus lancifolius (Combretaceae)

Purpose: Isolation, characterisation and structure elucidation of compounds obtained from Conocarpus lancifolius and screening of their pharmacological effects in vitro.Methods: After collection, authentication and extraction from whole C. lancifolius plants, screening for secondary metabolites, thin-layer  chromatography and subsequent open column chromatography were performed for phytochemical analysis and subsequent purification of the compounds. The chemical structures of the isolated compounds were elucidated using spectroscopic (UV-visible, infrared and mass) spectroscopy, and nuclear magnetic resonance (1H-NMR, 13C-NMR including BB, DEPT-135, 90 and two-dimensional correlation techniques, including HMBC and HSQC). The cytotoxic and antioxidant potentials of extracts and compounds obtained from C. lancifolius were evaluated using in vitro models.Results: Two ellagic acid derivatives, 2,3,8-tri-o-methylellagic acid (A) and 3-O-methylellagic acid 4-O-β-D-glucopyranoside (B), were isolated. Both compounds (A and B) were cytotoxic in a variety of cancer cell lines, including murine lymphocytic leukaemia (P-388, half-maximal inhibitory concentration (IC50) =3.60 and 2.40 μg/mL, respectively), human colon cancer (Col-2, IC50 = 0.76 and 0.92 μg/mL, respectively) and human breast cancer (MCF-7, IC50 = 0.65 and 0.54 μg/mL, respectively). Moreover, both compounds showed significant antioxidant potential in vitro.Conclusion: C. lancifolius extract and isolated ellagic acid derivatives (compounds A and B) possess cytotoxic and antioxidant properties. These findings suggest that C. lancifolius contains bioactive compounds that can be potentially developed as natural cytotoxic and antioxidant compounds. Keywords: Conocarpus lancifolius, Ellagic acid, Combretaceae, Cytotoxic activity, Antioxidan

Suitability of various plant derived gelling agents as agar substitute in microbiological growth media

Eleven putative gelling agents were investigated as agar substitutes. These included arrowroot (Maranta arundinaceae), coconut powder (Cocos nucifera), corn flour (Zea mays var. amylacea), gel rite (a water-soluble polysaccharide produced by Sphingomonas elodea), glue (Cyanoacrylates), katira gum (Cochlospermum religiosum), guar gum (Cyamopsis tetragonolobus L.), isubgol husk (Plantago ovata), pectin and rice (Oryza sativa L.) powder. Among these, guar gum was found a promising alternate candidate for agar. Media solidified with 2.8% guar gum was transparent and supportive for the growth of three test fungi (Trichoderma harzianum, Alternaria alternata and Alternaria solani) as good as agar. Guar gum also excelled in terms of cost benefit ratio when compared with agar. Guar gum fortified media was found to cost $0.005/L as compared to agar supplemented media costing$ 1.17/L. Further, guar gum is easily available and can be added with ease thereby serving as a suitable and inexpensive substitute of agar and thus, can be adopted for routine microbiological testing in resource poor countries.Key words: Guar gum, media, agar, gelling agents

Work environment and training transfer intentions: does organizational justice moderate their relationship?

The work environment plays a vital role in the transfer of the newly attained knowledge, skills, and abilities (KSAs) at the workplace. In the past decades, a series of studies have investigated the direct relationship between the work environment and training transfer. Surprisingly, empirical findings noted the inconsistent relationship between the work environment and training transfer. Whereas, the moderating effect between these relationships has been less examined in the training transfer literature. Therefore, addressing this gap, the prospective study was designed to investigate the moderating role of organizational justice as a potential moderator between the relationships of work environment and training transfer in Pakistani large-scale textile organizations (LSTO). Survey data were collected from 336 front-line managers by employing a multi-stage sampling technique. Structural equation modeling and hierarchical regression technique were used to test the hypotheses. The results showed that supervisor support, peer support, and opportunity to use learning (i.e., dimensions of work environment) correlate positively with training transfer. The findings also confirmed the moderating role of procedural justice and distributive justice (i.e., dimensions of organization justice) between the relationship of work environment and training transfer. These results underscore the critical role played by organizational justice to enhance the transfer of training at the workplace. This study shows, for the first time, that how organizational justice is an important mechanism to stimulate the work environment to training transfer

ENHANCEMENT IN OVERALL THERMAL EFFICIENCY OF A GAS TURBINE POWER PLANT USING COMBINED CYCLE SYSTEM

The gas turbines are one of the major resources of power generation in the world and its usage is increasing day by day. Although the gas turbines have several advantages over other systems (such as high power to weigh ratio, high rotational speed or fast activation capabilities) but they still waste the energy in the form of high temperature exhaust gases coming out of the gas turbine which pollute the atmosphere and affect the environment. A waste heat recovery system (WHRS) installed at Gas turbine exhaust helps not only to reduce the exhaust temperature of these gases emitting from the uptake into the atmosphere but also enables to produce useful steam for various processes. The air mass flow rate which enters the compressor has a direct relation with the performance of gas turbine power plant. The volumetric efficiency of the gas turbines decreases with rise in the temperature of the inlet air. The increase in temperature will reduce the density which results in the reduction of gas turbine efficiency. In the present work the steam produced from WHRS has been used in the vapor absorption system of refrigeration. The refrigeration system is utilized to cool the air at the entry of the gas turbine compressor power plant. It was observed in gas turbine power plant that there is a 10% increase in thermal efficiency
