Simulation of Complex Heat Transfer Phenomenon across the Composite Wall by Using COMSOL Multiphysics
Full text linkSteady state complex heat transfer phenomenon across a cold storage composite wall has been studied by using COMSOL 5.0 Multiphysics simulation software. The layers of composite wall are built with three different materials, pine, cork board and concrete. Inside and outside surface temperatures of composite wall are T1 = 255K and T4 = 298 K respectively. Without including convective resistance heat flux value is 17.15 W/m2 and with convective resistance it is reduced to 12.12 W/m2. The temperature profiles in each composite layer are linear at constant thermal conductivities. But it has been observed that this trend is changed when thermal conductivities are the function of temperature. COMSOL Multiphysics simulator results are compared with analytical results
Teaching children road safety using a simulated environment
Full text linkThe importance of road safety education is widely acknowledged; however, there is a lack of consistency in road safety interventions currently being used in UK schools. Furthermore, the majority of road safety educational programmes use knowledge-based methods, which do not necessarily translate to improved behaviour in real traffic environments. The use of virtual reality is starting to emerge as a viable option, as it allows for repeated risk-free practice. This study aimed to test the efficacy and playability of a virtual reality road crossing iPad-based game with children aged 7-9 years. A total of 137 children from primary school years 3 and 4 completed the study. The game comprised ten levels increasing in complexity. Participants navigated to a target using a magic portal into the virtual world (the iPad position matching the direction of travel). Remote, anonymous in-game data were collected and the results suggested that performance was significantly better on their final attempt compared to their first attempt, regardless of age of gender. Overall, the results suggest that the iPad-based game allowed the children to practice road crossing in an immersive environment, without risk, and could provide a useful, evidence-based addition to current road safety education in UK schools
Effect of Simulated Chemistry Practicals on Students’ Performance at Secondary School Level
Full text linkThe study was conducted to compare the performance of students working in chemistry laboratory with those working in chemistry laboratory supplemented with simulations at secondary school level. The focus of the study was to find out the effectiveness of laboratory work supplemented with simulation on the performance of students. The study was experimental in nature and posttest only control group design was used. Qualitative data is collected by means of interview of chemistry teachers. Quantitative data was also collected and analyzed. The sample comprised of 118 (60 males and 58 female) students and (02) Chemistry teachers of class IX of Public schools of Peshawar. The control group worked in the Chemistry laboratory under normal condition whereas experimental group performed practicals with the help of simulated software. At the end of the treatment practical examination was conducted on the pattern of Peshawar Board of Intermediate and Secondary Education (PBISE). The scores of both control and experimental groups were compared in three main areas i.e. written, viva voce and notebook. For the sake of comparison of control group and experimental group independent sample t-test was used. The result of t-test indicates that there is a significant difference between the performance of control and experimental groups with large effect size. The qualitative data was collected by means of interview which indicated that both the interviewees were motivated and showed keen interest in the simulated software. Both the respondents confirmed that the use of simulated software results in better understanding of concepts in students but at the same time both interviewees reported that it seems difficult to apply the simulated software in our system of Education. The performance of the students of experimental groups showed improvement, results in the rejection of hypotheses that there is no significant difference between the performance of students taught by conventional demonstration in laboratory and laboratory work facilitated with simulation. If proper physical facilities were available simulated software is the solutions of many problems faced by students and teachers in Chemistry laboratories
Validating Learning Organization in the Medical Profession: A Preliminary Analysis
No full textThis study investigates the underlying pattern of learning organisation practices among medical doctors using Learning Organization Survey (LOS) designed by Garvin, Edmondson and Gino (2008). The instrument was modified to adapt to settings in clinical care. A preliminary data of 150 medical doctors were used for reliability and exploratory factor analysis (EFA). Cronbach’s alpha indicated an excellent reliability score. The outcome of EFA was a seven-factor solution. While some subscales converged to new factors, the three building blocks of a learning organisation successfully retained the original items. The outcomes reveal that LOS in the context of medical vocation is reliable and valid at an initial stage. The three building blocks of a learning organisation as specified by Garvin et al. (2008) can, therefore, be instrumental in fostering continuous learning in medical vocation. The conception of the learning organisation, albeit important for continuous development of human resources for health in the 21st century, was not well researched in medical vocation. The present study, in this context, is an initial analysis that suggests grounds for future research. The findings call for further enquiries with an expanded sampling framework as well as further validation on LOS using confirmatory factor analysis
Shareholder’s Wealth perspective of Credit Risk: Evidences from Banking Sector of Pakistan
No full textThis study examines the effect of credit risk on shareholder’s wealth. Scheduled banks of SBP were taken as statistical frame. The results of the study indicate that overall credit risk has insignificantly and negatively effect on shareholders wealth; similarly indicator of credit risk such as ratio of non-performing loan to gross advance and provision allocated for non-performing loan and actual non-performing loans influence the earring per share and return on equity in significant manner. The non-performing loans has emerged like as the major indicator of credit risk as consequence of the finding of the study, whereas earring per share, return on equity and return on revenue are effective indicators of the wealth of shareholders. These results does matter categorically the banking sector in Pakistan as a developing country of South Asia where such practices are not very common.
THE IMPACT OF FISCAL POLICY ON ECONOMIC GROWTH: PANEL DATA ANALYSIS
No full text The economic transition after 1990’s from socialism toward free market economy has changed the role of state in connection of spending decisions and tax policy. The dynamics of fiscal policy has received less attention among researchers in the past. The present study is a comprehensive analysis of the effectiveness of fiscal policy for economic growth. The study examines the effects of fiscal policy on economic growth over the period of 2002 to 2014,based on International Financial Statistics (IFS) database and World Development Indicator (WDI) database.The studyanalyzes the impact of a fiscal shock on economic growth for 10 countries, with the use of panel ARDL econometric technique.The results of the study summarize the fact that fiscal policy is a key instrument in the process of economic growth in the sample economies.
EFFECTS OF FIRM SPECIFIC MEASURES AND BOARD ATTRIBUTES ON WORKING CAPITAL: EVIDENCE FROM TEXTILE INDUSTRY OF PAKISTAN
No full textThe core objective of this paper is to investigate whether firm specific variables and board attributes affect the working capital ratio of textile composite, textile spinning, textile weaving and overall sample of firms listed on KSE during 2008-2014. Profitability is positively related to working capital ratio in textile spinning, textile weaving and in over sample of firms. Alternatively, profitability is inversely related to working capital ratio in textile composite. Firm size, leverage and assets tangibility have shown consistent results and negatively related to working capital ratio in all regressions. Age is positively related to working capital ratio in textile composite and in overall sample of firms. Board size is unrelated to working capital ratio. Board composition is positively (in textile composite only) while CEO duality is negatively (in textile spinning only) related to working capital ratio. In sum, firm specific variables have a significant while board attributes have a minute impact on working capital ratio.

Investigating the impact of Consumer’s Involvement, Risk-taking Personality, Internet Self-Efficacy, Life Style and Privacy Concern on Online Purchase Intention and Shopping Adoption
No full textThe purpose of this paper is to study the impact of consumer’s psychological traits, lifestyle and privacy concern on online purchase intention. The core issue is ‘to what extent consumer’s involvement, risk-taking personality, internet self-efficacy, life style and privacy concern determines online purchase intention and online shopping adoption’. In causal study design, 590 consumers with convenience sampling technique is used through structured questionnaire. Data analysis undertaken through SEM indicates a significant relation of lifestyle with involvement, risk-taking personality, internet self-efficacy and privacy concern. Whereas, online purchase intention holds significant relationship with internet self-efficacy, lifestyle and online shopping adoption, no significant relationship was proved between involvement, risk-taking personality and privacy concern. E-retailers should focus on building satisfaction in the potential and existing customers by investing in strategies to overcome the perceived risk of online-shopping
Impact of FDI and Real Effective Exchange Rate on Saving and Economic Growth Nexus in Pakistan: An Empirical Analysis
No full textAbstractEconomic growth is influenced by different macro variables. Saving is also important among them. In this study, we attempt to reexamine the saving-growth nexus linking through FDI investment inflows, real effective exchange rate in Pakistan. For analysis we used time series data for net national saving, GDP growth rate, FDI inflows, and real effective exchange rates at constant prices during 1982 to 2015. We employed ADF for unit root,Johansen’s cointegration technique/approach to diagnose robustness of long-run,Model of (ECM) short run dynamics among these variables. Empirical results show that GDP growth rate is significantly positively related to net national saving, in long-run & short-run. These finding in supporting to ”Keynesian approach, permanen-income hypothesis’s validity” in Pakistan. Further results finding identify the impact of exchange rate which has positive impact on national saving in long-run. Complementary role of FDI in saving-growth nexus has positively insignificant impact on national saving in Pakistan. Its coefficient explains, it has very marginal positive impact.
