Abstract: To compliment an EBP course for allied health care professionals and CAM practitioners, we undertook a questionnaire survey to assess learning needs. We developed a questionnaire to measure allied health care professionals and CAM practitioners' basic knowledge, skills and beliefs concerning the main principles of EBP. The questionnaires were administered to all attendees of one-day EBP workshops.During 2004–5 we surveyed 193 allied health care professionals and CAM practitioners who attended one-day EBP courses prior to commencement of teaching. Of the respondents 121 (62.7%) were allied health care professionals and 65 (33.7%) practitioners stated that they work in the CAM field Our survey found that the majority of the respondents had not previously attended a literature appraisal skills workshop (87.3%) or received formal training in research methods (69.9%), epidemiology (91.2%) or statistics (80.8%). Furthermore, 67.1% of practitioners specified that they felt that they had not had adequate training in EBM and they identified that they needed more training and education in the principles of EBM (86.7%). Differences in knowledge and beliefs concerning EBP amongst allied and CAM practitioners were found and length of time since qualification was also found to be an important factor in practitioner's beliefs. More CAM practitioners compared to allied health professionals accessed educational literature via the Internet (95.3% v 68.1%, p = 0.008). Whilst, practitioners with more than 11 years experience felt that original research papers were far more confusing (p = 0.02) than their less experienced colleagues.The results demonstrate that practitioner's learning needs do vary according to the type of profession, time since graduation and prior research experience. Our survey findings are exploratory and will benefit from further replication, however, we do believe that they warrant consideration by allied health care and CAM tutors and trainers when planning EBP t

Abstract: This study examines the impact of on-the-job training (OJT) on job performance. Variables were selected from existing research studies to assess the effects of OJT on job performance of employees. The researcher uses database of 10 telecom companies situated in Islamabadregion for analysis and determines that training has both a positive and a significant effect on both wage growth and change in job performance scores of workers. As implied by the model,employer-financed training is positively related to wage growth and job performance which shows the robustness of the relationship between training and worker productivity. OJT increases the skill level of workers and become more productive by which they deserve higherdemand in the market. Organizations offer higher wages to hire them because of their higher skill levels. This research finding provides several important indicators that will influence the way economists and managers think about the relationships between OJT and wages and job performance.

Abstract: A re-thinking and clear understanding of the factors underlying a country's balance of trade position is needed as the global trade regime becomes more liberalized. The relationship between the overall trade balance and its determinants as propounded in the standard models may not necessarily be the same with the bilateral trade balances. This study has developed a model of bilateral trade balance that captures the effects of all factors influencing trade balance as suggested by elasticity, absorption, and monetary approaches and the popular Gravity Model with some extensions. Specifically, the present paper postulates that the relative factors determine the trading pattern, and hence the trade balance of a country in bilateral trade with partners while in the earlier models absolute factors determine the trade balance,. Using standard panel data techniques the model is empirically tested and the results show significant effects of all the relative factors on the bilateral trade balance of Bangladesh in trading with her partners. The robustness check of the model ensures the validity of the specification.

Abstract: The Paper examines/analyzed the factors contributing exchange rate vitality in Pakistan. The study was conducted on some major factors contributing to exchange rate volatility, and their relative importance. Annual data for the period 1975-2010 is used, taken from Economic Survey of Pakistan (various issues) and International Financial Statistics. The main variables used to check variability are inflation, Growth rate, imports and exports on exchange rate volatility. Simple Linear Regression model with ordinary least method (OLS) is used to analyze the results. The study revealed that inflation is the main factor affecting exchange rate in Pakistan. The study further show that the second important variable which bring more variation in exchange rate is economic growth, while order of export and import in variation lies at third and fourth position. Based on the finding of the study it is recommended to harmonize fiscal policies with monetary policy first and then make effective link of both these policies with trade policy.

Abstract: Chlorpyrifos is a commonly used pesticide of organophosphate group, which causes toxicological effects in non-target organisms especially fish and frogs. In the present study, the genotoxicity of sublethal concentrations of chlorpyrifos was observed in the erythrocytes of common Indus valley toad, Bufo stomaticus, using the Alkaline Single-Cell Gel Electrophoresis (Comet) assay. In the first step, acute toxicity of chlorpyrifos was evaluated by exposing the tadpoles to high concentrations of the pesticide. The acute LC50 value of chlorpyrifos, calculated by Trimmed Spearman-Karber (TSK) in static bioassay, was found to be 930.0 μg/L. On the basis of acute LC50 value, the tadpoles were exposed to three sublethal concentrations (155, 233 and 465 μg/L) of chlorpyrifos for 96 h. Blood cells were collected at every 24

Similarity Solutions of MHD Mixed Convection Flow with Variable Reactive Index, Magnetic Field, and Velocity Slip Near a Moving Horizontal Plate: A Group Theory Approach
W. A. Khan,Md. Jashim Uddin,A. I. Md. Ismail
Mathematical Problems in Engineering , 2012, DOI: 10.1155/2012/183029
Abstract: The mixed convection of Newtonian fluid flow along a moving horizontal plate with higher-order chemical reaction, variable concentration reactant, and variable wall temperature and concentration is considered. Velocity slip and the thermal convective boundary conditions are applied at the plate surface. The governing partial differential equations are transformed into similarity equations via dimensionless similarity transformations developed by one-parameter continuous group method. The numerical solutions of the transformed ordinary differential equations are constructed for velocity, temperature and concentration functions, the skin friction factor, the rate of heat, and the rate of mass transfer using an implicit finite difference numerical technique. The investigated parameters are buoyancy parameters , , chemical reaction parameter , suction/injection parameter , velocity slip parameter convective heat transfer parameter , magnetic parameter , Prandtl number Pr and Schmidt number, Sc. Comparison with results from the open literature shows a very good agreement.

Mathematical Problems in Engineering , 2012, DOI: 10.1155/2012/934964
Abstract: Steady viscous incompressible MHD laminar boundary layer slip flow of an electrically conducting nanofluid over a convectively heated permeable moving linearly stretching sheet has been investigated numerically. The effects of Brownian motion, thermophoresis, magnetic field, and heat generation/absorption are included in the nanofluid model. The similarity transformations for the governing equations are developed. The effects of the pertinent parameters, Lewis number, magnetic field, Brownian motion, heat generation, thermophoretic, momentum slip and Biot number on the flow field, temperature, skin friction factor, heat transfer rate, and nanoparticle, volume fraction rate are displayed in both graphical and tabular forms. Comparisons of analytical (for special cases) and numerical solutions with the existing results in the literature are made and is found a close agreement, that supports the validity of the present analysis and the accuracy of our numerical computations. Results for the reduced Nusselt and Sherwood numbers are provided in tabular and graphical forms for various values of the flow controlling parameters which govern the momentum, energy, and the nanoparticle volume fraction transport in the MHD boundary layer.

Journal of Applied Mathematics , 2012, DOI: 10.1155/2012/648675
Abstract: Two-dimensional, steady, laminar and incompressible natural convective flow of a nanofluid over a connectively heated permeable upward facing radiating horizontal plate in porous medium is studied numerically. The present model incorporates Brownian motion and thermophoresis effects. The similarity transformations for the governing equations are developed by Lie group analysis. The transformed equations are solved numerically by Runge-Kutta-Fehlberg fourth-fifth order method with shooting technique. Effects of the governing parameters on the dimensionless velocity, temperature and nanoparticle volume fraction as well as on the dimensionless rate of heat and mass transfer are presented graphically and the results are compared with the published data for special cases. Good agreement is found between numerical results of the present paper and published results. It is found that Lewis number, Brownian motion and convective heat transfer parameters increase the heat and mass transfer rates whilst thermophoresis decreases both heat and mass transfer rates.
