An Empirical Analysis of Australian Labour Productivity

This study presents a model capturing sources of Australian aggregate labour productivity using annual time series data from 1970 to 2001. Labour productivity, or real output per hour worked, in this model is determined by real net capital stock in information technology and telecommunications (ITT), real net capital stock in the non-ITT sector, trade openness, human capital, the wage rate, international competitiveness, and the union membership rate. Given the lack of long and consistent time series data, multivariate cointegration techniques are inappropriate as the cointegration results will be sensitive to the lag length, the inclusion or exclusion of the intercept term or a trend in the cointegration equation and/or the vector autoregression (VAR) specification. Therefore, the Engle-Granger representation theorem and the Hausman weak exogeneity test have been employed to determine the short and long-term drivers of Australian productivity. Empirical estimates indicate that, in the long-term, policies aimed at promoting various types of investment, trade openness, international competitiveness, and the use of wage as a stimulant in a decentralised wage negotiation system, will improve labour productivity. In the short term, all the above variables except for human capital and labour reforms, which both need more time to evolve, determine productivity performance.     

Modeling integrated supply chain logistics in real-time large-scale disaster relief operations

The goal of this research is to develop a comprehensive model that describes the integrated logistics operations in response to natural disasters. We propose a mathematical model that controls the flow of several relief commodities from the sources through the supply chain and until they are delivered to the hands of recipients. The structure of the network is in compliance with FEMA's complex logistics structure. The proposed model not only considers details such as vehicle routing and pick up or delivery schedules; but also considers finding the optimal locations for several layers of temporary facilities as well as considering several capacity constraints for each facility and the transportation system. Such an integrated model provides the opportunity for a centralized operation plan that can eliminate delays and assign the limited resources to the best possible use.A set of numerical experiments is designed to test the proposed formulation and evaluate the properties of the optimization problem. The numerical analysis shows the capabilities of the model to handle the large-scale relief operations with adequate details. However, the problem size and difficulty grows rapidly by extending the length of the operations or when the equity among recipients is considered. In these cases, it is suggested to find fast solution algorithms and heuristic methods in future research.     

The Ten Commandments Perspective on Power and Authority in Organizations

Power and authority in terms of the Ten Commandments (TCs) are discussed. The paper reviews the TCs in Christianity, Judaism, and Islam. The treatment and basis for power and authority in each religion are clarified. Implications of power and authority using the perspective of the TCs are provided. The paper suggests that in today's business environment people tend to be selective in identifying only with certain elements of the TCs that fit their interest and that the TCs should be viewed as general moral guidelines.     

Estimating road traffic mortality more accurately: use of the capture-recapture method in the West Azarbaijan province of Iran

The study estimates the rate of fatal road traffic injuries (RTIs) by population and road-users group in one Iranian province. The capture - recapture method was employed, using both the death register and the forensic medicine register over one year. They recorded totals of 669 and 665 RTIs respectively, giving a non-overlapping number of 897 cases. An estimate of 1018 fatalities occurred, at rates of 34 per 100,000 of the population for all road users aggregated, 10 per 100,000 for pedestrians and 25 per 100,000 for other road users. Coverage was somewhat better for victims less than 15 years of age, and also for males. The method showed 121 under-reported cases in both sources; however, it can help Iranian policy-makers to produce a good estimation of fatal RTIs number each year, when following up current RTIs-prevention programmes. Yet, given that each registry operates separately, optimum coverage will only be obtained when both sources are integrated and work together.
