The main aim of this study is to assess the physical work capacity of bricklayers with focus on the energy expenditure during work. Eighty Nine bricklayers’ working on various sites in Ibadan and Eruwa towns of Oyo State, Nigeria are used for the study. Correlation and regression analysis using SPSS 16.0 Statistical Package was used to determine the relationship between VO2 given the age and weight of the subjects; % RHR(Relative Heart Rate) and working heart rate (HRW) given weight; VO2 and %RHR given Body Mass Index (BMI).
The results showed that the mean energy expenditure of bricklaying was 1.5l/min of oxygen (7.23Kcal/min, using a conversion factor of 4.82) which classified bricklaying as “heavy work”. A rest allowance of 64.45% (38.67 minutes rest for 60 minutes work duration) was calculated.
It was concluded that there is a need to redesign the work content of the aforementioned occupation in order to reduce excessive strain on the workers, which in turn will increase productivity.

Motivation is one of the most important factors influencing workers & apos; productivity. An increase in workers & apos; motivation could add more value to organizations & apos; structure and influence the profitability, significantly. In this paper, we study different factors on demotivating workers using questionnaire consist of various questions. The questionnaire is distributed among some employees who work for rubber production units located in Esfahan, Iran. The results of this survey indicate that discrimination on annual job compensation, entrusting responsibilities and unpleasant relationship with family partner are some of the most important factors influencing employees & apos; motivation. While financial factors play important role on increasing employees & apos; motivation, non-financial factors are considered more important.

Sugar is one of the strategic goods in the basket of households in each country and it plays an
important role in supplying the required energy. On the other hand, it is one of the goods, which
Iranian government is about to change its subsidy strategies. To design useful sugar subsidy
strategies, it is necessary to know sugar position in the basket of households and be familiar
with households & apos; sugar demand or consumption behavior. This research estimates sugar demand
for Iranian households by using time series of 1984-2008, which is taken from central bank of
Iran. In this paper, first independent and dependent variables of household sugar demand
model are chosen based on the literature review and theory of demand. Then, sugar demand is
estimated by OLS technique and linear regression. The preliminary statistical observations such
as Durbin-Watson, F statistic and R2 indicate that the regression is admissible. The results seem
plausible and consistent with theory and show that sugar demand in Iranian households is
associated with household expenditure, relative sugar price, family size and indicate that
demand of sugar is affected during the war time. The results also show the income elasticity is
0.8 and price elasticity is -0.2 which means sugar is essential good for Iranian households and is
inelastic to price.

Service quality plays an important role in health care systems since hospitals are responsible for people & apos; s lives. This study presents an effective approach for evaluating and comparing service qualities of four hospitals. Service quality consists of different attributes and many of them are intangible and difficult to measure. Therefore, we propose a fuzzy method to resolve the ambiguity of the concepts, which are associated with human judgments. SERVQUAL model is used to evaluate the respondents & apos; judgments of service quality and multi attribute decision making approach is implemented for the comparison among hospitals. The paper use analytical hierarchy process (AHP) for obtaining criteria weight and TOPSIS for ranking the cases.

One of the most important issues on revenue management in banking industries is the assignment of loan to customers. In fact, a big portion of banks' revenue is from loan assignment and choosing appropriate customers for loan assignment not only reduces the financial risk but also it can increase the revenue. In this study, we perform an empirical study to find out whether customers' financial statements could provide enough information about customers for loan assignment. The other objective of this study is to find out whether banks' officials could understand about the details of customers' financial statements. Finally, we want to find out whether there is any relationship between unpaid loans and customers' credit rating. The present study is executed on an Iranian bank by distributing a questionnaire analyzing the results. The results indicate that there are some strong evidence that financial statement could help bank official determine customers' credit rating. The survey also concludes that highly education and experienced employees are the best people for devoting best credit rating for customers.

The personality of an entrepreneur plays an important role on the success of creating new ideas. There are different characteristics such as courage, hardness, braveness, which could help an entrepreneur reach his/her goals. In this paper, we present an empirical study to learn more about students who are supposed to act as entrepreneur to create jobs in different fields of accounting, computer science, mechanical engineering, etc. In this paper, There are seven aspects of accepting reasonable risk, locus of control, the need for success, mental health conditions, being pragmatic, tolerating ambiguity, dreaming and the sense of challenging in our study to measure the level of entrepreneurship. We implement ANOVA test to measure different entrepreneurship characteristics of students who study in various educational fields. The case study is associated with Sama private university located in city of Zanjan/Iran. The results indicate that there are not meaningful differences among pairwise comparison of many engineering fields.

Teenagers are believed the people who are supposed to build the world & apos; s future. High-risk behaviors such as addiction to drugs, smoking cigarettes, sex, etc. could significantly hurt teenagers and there must be some supporting programs to reduce these issues as much as possible. This paper performs an empirical investigation to study different factors influencing high- risk behavior among teenagers who live in a city of Esfahan, Iran. The proposed study designs a questionnaire and distributes between two groups of female and male teenagers. The results indicate that while there is a meaningful relationship between high-risk behaviors and average teenagers grades among male teenagers there is no meaningful relationship between high-risk behaviors and teenagers & apos; grades among female students. The results also indicate that there is a meaningful difference between gender and high-risk behavior. The season of birth for female and male students is another important factor for having high-risk behaviors. While the order of birth plays an important role among male students, the order of birth is not an important factor among female teenagers. Finally, the results indicate that teenagers & apos; parental financial affordability plays a vital role on both female and male teenagers.

Empowering workers play an essential role on increasing productivity in any organization. The service industries such as insurance companies or banks mostly rely on their own people to retain their customers and incomes. The recent increasing trend on the number of private banks in Iran has increased competition among existing banks. The banking industry strives to empower its employees as much as possible in an attempt to maintain market share by not losing its customers. In this paper, we present an empirical study to detect the most important factors empowering bank employees. The study is implemented for a recently established private bank with 228 people with 32 questions where 15 questions are focused on empowering employees. The results are analyzed using statistical tests and descriptive methods. The results indicate that leadership, academic qualification, appropriate policy and strategy, cooperation and processes play important role on empowering and enabling bank & apos; s employee.

The data is analyzed using the techniques of rank correlation coefficient and multiple regression analysis. All the findings are tested at 0.01 and 0.05 levels of significance. The result concludes that altruism, conscientiousness, and civic virtue have strong positive impacts on the organizational citizenship behavior in the context of higher education institutes in Pakistan.
