AbstractOptimization of activities with the aim to provide quality service in conditions of high profitability, is one of the main objectives chased by managers in transportation companies. As a consequence, directing the attention towards monitoring of maintenance activities of vehicles fleet, can achieve desired results. Two of the most important issues related to the maintenance activity, is the increase of reliability and reduction of fuel consumption of the vehicles fleet. Aforementioned actions represents a way forward for raising the quality and profitability of services offered. In this paper, the main ways of monitoring the fuel consumption, in order to reduce it and increase the reliability of transportation vehicles fleet, are presented. For the evaluation of the maintenance system and the degree of influence of malfunctions recorded on the fuel consumption, using the Pareto -ABC method, following case study on a fleet of buses for urban public transport has been conducted. Results obtained highlights the deficiencies of the maintenance process carried out and constitutes a solid base for the reorganization of the maintenance activity, involving preventive maintenance activities, in order to contribute decisively to the results targeted by the management of transport companies.

Maintenance Schedules

Maintenance is crucial to system performance and reliability of a machine for an industry. Machine maintenance system in small and medium industries in Malaysia usually consists of manual file management system, which records all the conducted maintenance works. However, a maintenance system should be more complex to include the scheduling of maintenance activities. This paper presents the findings of studies on the implementation of preventive maintenance schedule conducted at Aman Sales And Services Sdn. Bhd. and Ladang Sabah Palm Oil Mill both located in Sabah, Malaysia. In this study, data form previous maintenance works or activities were collected from both companies. The data were then analyzed. The analysis indicates that reduction in time can be obtained by combining similar or repetitive tasks guided by recommendation from the machines’ manuals. This analysis provides foundation for developing an improved preventive maintenance schedule for each company. The new preventive maintenance schedules are found to be able to reduce the breakdown time ranging from as low as 25% to as high as 50%. This reduction signifies the efficiency of the proposed maintenance schedule.

Performance Results

In this paper we show that not taking into account the fact that fund managers “deviate” from their stated categories biases upward their alphas. When evaluating fund managers most studies compare managers against the S&P 500 regardless of the sectors managers actually invest in. This procedure does not take into account that an important proportion of US stock managers invest in medium and small companies. This neglect biases performance results. In the international stock arena, not only do studies use the incorrect benchmark but they also neglect to take into account the fact that managers deviate from their stated sector. In this paper we not only employ the correct category the managers invest in but we also take into account the fact that managers systematically drift away from their stated category. This drift occurs for approximately half the funds examined and causes the estimated alpha of managers to be on average 45 basis points higher than it should be if we were to undertake the multiple regression that fund drift demands. In addition to using the right benchmarks, adjusting for “drift” in this paper we chose to use as “benchmarks” the ETF’s in each category so as to compare managers not against theoretical constructs, but against an actual investable vehicle in the corresponding category.

Preventive maintenance (PM) is the basic policy in maintenance system and widely used in companies all over the world. However, its advantages are not always fully received by the company because it is not carried out according to prescribed planning and schedule. This is because of improper implementation of the PM that leads to the major problem of increasing number of machine downtime. One of the reasons for the problem is ineffective PM checklist used during the implementation. Therefore, the aim of this paper is to reduce the planned downtime for PM by analyzing and enhancing the PM checklist. This is to show the importance of having good PM checklist as it simplified technicians workload and can reduce machine downtime if conducted properly. Consequently, good PM checklist will show the performances of the technicians doing their tasks as well as the performances of the machines to be operated in good operational condition.

This research examines the factors affecting the financial literacy of Vietnamese adults. Using a sample of 266 observations of adults in 2 big cities in Vietnam (Hanoi and Vinh in Nghe An Province), the author evaluates the literacy level of adults in these urban areas. The financial literacy of the interviewed people is low. The multiple regression results show that lower financial literacy levels associate with higher age and married status and higher financial literacy levels associate with higher education, more family members, the person making financial decisions and the person attending a useful financial course. This research also explores the association between financial literacy and financial behaviors of individuals employing logistic models. It is found that higher financial literacy associates with less probability of overspending and higher probability of saving money and careful spending. Higher financial literacy is also found to associate with higher probability of opening a savings account and making various investments.

In the debate on the Native Authority (Amendment) Law of 1955, the late Premier of the North, Sir Ahmadu Bello, Sardauna of Sokoto, replying to the demand that ‘it is high time in the development of local government systems in this Region that obsolete and undemocratic ways of appointing Emirs’ Councils should close’, commented that ‘the right traditions that we have gone away from are the cutting off of the hands of thieves, and that has caused a lot of thieving in this country. Why should we not be cutting (off) the hands of thieves in order to reduce thieving? That is logical and it is lawful in our tradition and custom here.’ This could be read as a defence against social change, a recrudescence of ‘barbarism’ after the inroads of pax Britannica, and a plea for the retention of the status quo and the entrenched privilege of the political elite.
