Determinants of credit growth in Saudi Arabia are investigated.

A panel approach is applied to macroeconomic and bank-level data spanning 2000 ‐15.

Bank lending is supported by strong bank balance sheet conditions (high capital ratio, and growth of NPL provisioning and deposits), and higher growth of both oil prices and non-oil private sector GDP. Lower bank concentration also helps, likely through greater competition, so does stronger institution. Consistent with the literature, lending by Islamic banks may be more responsive to economic activity. Lending remained robust in 2015 despite oil prices having declined, helped by strong bank balance sheets and as banks reduced their holdings of “excess liquidity”. To support bank lending in the period ahead, bank balance sheets need to remain strong. Fiscal adjustment and a reduced reliance on banks to finance the budget deficit would support credit provision to the private sector.

The paper is first to analyze in detail determinants of bank lending in Saudi Arabia applying a panel approach to bank level data, and draws critical policy implications.

Outlines the international travels of Clement Allan Tisdell in the period 1965‐1996 and an Australian journey made to Adelaide in 1962 for academic reasons and indicates the influence of these journeys on his publications, outlook and intellectual evolution. Emphasises how varied the life of an economist can be and the importance of international social contacts for academic development. Because of the extent of his travels, descriptions and analysis of most of his journeys are brief. Consequently, a longer story still remains untold.

The purpose of this paper is to analyse the leadership tendencies of Japanese people and relevant changes over time while exploring their task and relationship orientations on the basis of culture.

In order to explore the behavioural tendencies of working adults in the Japanese workplace, the paper focused on comparing the leadership orientations of 231 respondents on the basis of age, gender and public/private sector work experience. To deepen the understanding of Japanese leadership orientation, the authors precisely examine Japanese culture, organisation and management practices.

Japanese respondents have a significantly higher score on the relationship orientation. Their task score is also in the moderately high range. Japanese males were found to be more task‐oriented. No differences were found based on public/private sector work experience. However, older Japanese have a significantly higher focus on task orientation compared to their younger colleagues.

One of the limitations is the small number of responses. One specific limitation is the fact that this study was conducted with a convenient sample population. Future studies can compare specific populations in different parts of the country with similar working backgrounds and demographic variables.

The findings that Japanese employees are more focused on their relationship but that they also have a moderately high task orientation score are useful for managers and expatriates working in Japan to understand the behavioural tendencies of Japanese people and the relevant changes over time.

Japan is a high‐context culture; therefore Japanese people are traditionally regarded to be relationship‐oriented, and this was confirmed academically in the findings of this research. However, the paper showed that the Japanese also have a moderately high task orientation.

The total capacity of ambulances in metropolitan cities is often less than the post-disaster demand, especially in the case of disasters such as earthquakes. However, because earthquakes are a rare occurrence in these cities, it is unreasonable to maintain the ambulance capacity at a higher level than usual. Therefore, the effective use of ambulances is critical in saving human lives during such disasters. Thus, this paper aims to provide a method for determining how to transport the maximum number of disaster victims to hospitals on time.

The transportation-related disaster management problem is complex and dynamic. The practical solution needs decomposition and a fast algorithm for determining the next mission of a vehicle. The suggested method is a synthesis of mathematical modeling, scheduling theory, heuristic methods and the Voronoi diagram of geometry. This study presents new elements for the treatment, including new mathematical theorems and algorithms. In the proposed method, each hospital is responsible for a region determined by the Voronoi diagram. The region may change if a hospital becomes full. The ambulance vehicles work for hospitals. For every patient, there is an estimated deadline by which the person must reach the hospital to survive. The second part of the concept is the way of scheduling the vehicles. The objective is to transport the maximum number of patients on time. In terms of scheduling theory, this is a problem whose objective function is to minimize the sum of the unit penalties.

The Voronoi diagram can be effectively used for decomposing the complex problem. The mathematical model of transportation to one hospital is the P‖ΣU_j problem of scheduling theory. This study provides a new mathematical theorem to describe the structure of an algorithm that provides the optimal solution. This study introduces the notion of the partial oracle. This algorithmic tool helps to elaborate heuristic methods, which provide approximations to the precise method. The realization of the partial oracle with constructive elements and elements proves the nonexistence of any solution. This paper contains case studies of three hospitals in Tehran. The results are close to the best possible results that can be achieved. However, obtaining the optimal solution requires a long CPU time, even in the nondynamic case, because the problem P‖ΣU_j is NP-complete.

This research suggests good approximation because of the complexity of the problem. Researchers are encouraged to test the proposed propositions further. In addition, the problem in the dynamic environment needs more attention.

If a large-scale earthquake can be expected in a city, the city authorities should have a central control system of ambulances. This study presents a simple and efficient method for the post-disaster transport problem and decision-making. The security of the city can be improved by purchasing ambulances and using the proposed method to boost the effectiveness of post-disaster relief.

The population will be safer and more secure if the recommended measures are realized. The measures are important for any city situated in a region where the outbreak of a major earthquake is possible at any moment.

This paper fulfills an identified need to study the operations related to the transport of seriously injured people using emergency vehicles in the post-disaster period in an efficient way.
