Learning style preference and critical thinking perception among engineering students
Engineering education plays a vital role towards modernization of world. Therefore, engineering students need to be nurture with multiple skills like learning preferences and critical thinking skills. This study has been conducted to identify the learning style preferences and critical thinking perception of the engineering students from three programs electrical engineering, mechanical engineering and civil engineering at Universiti Tun Hussein Onn Malaysia (UTHM), Johor. Survey research design was applied in this study. The quantitative data was collected by two questionnaires Index of Learning Styles (ILS) that is based on Felder-Silverman Learning Style Model (FSLSM) and Critical Thinking Skills (CTS) questionnaire which consists of analysis, evaluation, induction and deduction in terms of problem solving and decision making. A total of 315 final year engineering students were participated in this study. Data was analyzed in descriptive and inferential statistics involving tests Analysis of Variance (ANOVA), Pearson Correlation and linear regression. The study discovered that engineering students are preferred to be visual learners (83.80%). Visual learning style denotes FSLSM input dimension and visual learners learn best by diagrams, charts, maps and graphical presentations. This study also found that engineering students possess critical thinking perception in all dimensions. However, there is no statistical significant difference of learning style found among engineering programs as “p” value found 0.357. Whereas, there is statistical significant critical thinking difference found among engineering programs as “p” value found 0.006. Lastly, findings revealed that there is no significant relationship found between learning styles and critical thinking skills. The study findings suggested that providing preferred learning style (visual learning style) in classroom will enhance students’ academic achievement and increase their cognitive level. This study might serve as a guideline for educators to facilitate learners to enhance their learning and thinking for better outcomes in academia as well as in workplace

The Impact of Supply Chain Capabilities on Logistic Efficiency for the Construction Projects
Rapid technological advancements force organizations to be more proactive and efficient it operations while previous studies revealed that most of the public sector projects go over in term of time and cost. Although extensive literature is available but only for the private sector, the investigations on the public sector are scarce. After plentiful literature, it has found that timely and sage supply chain is a major hurdle. Various strategies and approaches have been proposed to tackle the situation but after a thorough investigation, it was found that flexibility and collaboration are the topmost influencing factors in improving logistic efficiency. Thus the aim of this study is to empirically verify the positive impact of flexibility and collaboration on logistic efficiency. A questionnaire was adopted and distributed by random sampling to the strategic level of the construction projects in the city of Lahore, Pakistan. Multiple regressions were applied through SPSS. The finding of the study revealed that flexibility contributes 33%, collaboration contributes 35.5% in the logistic efficiency. It can be concluded that construction projects must be flexible and force stakeholders for collaboration. This study added in the frame of knowledge as new findings for public sector projects. This study will help the managers in completing their projects timely and accurately
Needs assessment regarding occupational health and safety interventions among textile workers: A qualitative case study in Karachi, Pakistan
Objective: To determine the perceived health and safety needs identified by textile workers, managers and experts as well as direct observation of the prevailing health and safety practices in the textile industry.Methods: The qualitative study using the needs assessment conceptual framework was conducted in July-August 2015 in Karachi, and comprised focus group discussions with textile workers, in-depth interviews with factory managers and health and safety officers, and key informant interviews with relevant stakeholders and experts. A walk-through survey was also conducted in selected mills for which the Checklist of hazards in textiles was used.Results: A total of 6focus group discussions, 6 in-depth interviews and 5 key informant interviews were conducted. Workers were found to have limited knowledge of occupational hazards, preventions and diseases. They identified lack of awareness and non-existent safety mechanisms as areas for improvement. Managers thought preventive practices and health services were not standardised while influence of buyers in the form of international business regulations and legislations were thought to be the enabling factors for enforcing health and safety standards. Poor governance, lack of knowledge regarding labour rights, low literacy level, poor compliance and low wages were the barriers for health promotion at workplace, as identified by the experts. Walk-through survey found mechanisms in place for fire safety, but the workers and managers were generally not using Personal Protective Equipment despite the presence of several hazards at workplace.Conclusions: There was found a need for context-specific occupational health and safety interventions at individual, organisational and policy levels
Application of the GPS technology to assess time-location pattern of undergraduate students at a private medical university in Karachi, Pakistan: A pilot study
To compare time-location pattern of undergraduate university students through GPS and diary method, and with level of physical activity, a cross-sectional survey was conducted from September 2012 - May 2013 involving 50 undergraduate students from Aga Khan University. Data were recorded through GPS, diary method, International Physical Activity Questionnaire (IPAQ-L) and accelerometer (ActiGraph). Median self-reported time spent in the indoor-inside the campus, indoor-outside the campus and outdoor environment was 405 (IQR:300-540), 720 (IQR:465-840) and 300 minutes (IQR:180-495) respectively, while 52% of the students were in moderate, 40% vigorous and 8% in mild categories of physical activity. Mean differences in location (GPS versus diary method) were statistically insignificant; indoor residential, -30.2, indoor other, -26.2, outdoor at rest, 45.9 and outdoor travelling, 10.5 minutes. We conclude that students spent most of their time indoors-outside of campus and majority were physically active, while also demonstrating the applicability of GPS and ActiGraph for such studies

Effect of different types of stenosis on generalized power law model of blood flow in a bifurcated artery
This study is focus on generalized power law model of blood flow in a stenosed bifurcated artery under the effect of different types of stenosis. Stenosis can cause the narrowing of the artery that may reduce the flow of blood supply to the heart, and this may lead to the heart attacks. The geometry of the bifurcated artery with different classification of stenosis locations is considered in order to shows four possible morphologies formation of plaque from healthy artery to disease artery. The bifurcated artery is modelled as a two-dimensional rigid wall since the wall of a disease artery is reported to be less flexibility. Few assumptions are considered such as blood are incompressible, laminar, steady and characterized as the generalized power-law model. Simulation results are obtained using COMSOL Multiphysics 5.2, which is a software that based on the finite element method to solve this problem. Results concerning the effect of different locations of stenosis on generalized power law model of the blood flow characteristic such as streamlines pattern are discussed
