It is central to the sustainable development debate. The aim of this research is to examine the effects of urban landuse and its impact on selected public utility services in Akure with a view to improve strategies to protect these utilities for sustainable development. The research was conducted using remote sensing, Geographical information System and questionnaire to collect the required data for the purpose of fulfilling the objectives of this study. In this study of analyzing the urban landuse change, 2010 and 2018 IKONOS are used in a post classification comparison analysis to map the landuse changes and identify the conversion process in Akure. The landuse change statistics results obtained revealed that residential landuse has changed rapidly for the periods (2010-2018). The results also show increase in commercial landuses between the same periods. The results of the analysis reveal that the built-up area has been growing rapidly for the periods (2010-2018). Findings show that, housing provision (residential), business purpose (commercial) and educational (institution) are the major causes of land use change in the study areas. To reduce the effect of land use expansion in the study areas, policy measures were recommended which include regulating the growth and spread of development, regional development programs. In our opinion, the information provided by these technologies could help city planners and policy makers to attain and sustain future urban development.展开更多

Overall, there is a high pressure to increase productivity and reduce operating costs. The need to adapt to the new environment is pushing public organizations to implement Lean Management strategies in accordance with Private Sector standards. However, the limited budget, public deficits and debts, bureaucratic culture, political dependence and lack of transparency present several issues. These pose a serious threat to successful implementation of Lean practices in the long-run. Lack of relevant research and dichotomous role of public service organizations make this study very interesting. This research paper is aiming at exploring and highlighting the impact of the most important Critical Success Factors (CSFs) for the effective integration of Lean Management principles in Public Utility organizations in Greece by combining bibliographic research and empirical—with the quantitative method-research through case studies. <strong>Research Methodology: </strong>The research method combines bibliographic research and empirical—with the quantitative method. Quantitative method was employed on a sufficient sample of public employees from two of the largest public companies of Greece: Public Power Corporation (PPC S.A.) and Athens Water Supply and Sewerage Company (EYDAP S.A.) in order to investigate the impact of the most important CSFs on successful Lean Transformation of them. <strong>Findings:</strong> Quantitative findings from this research illustrated that the most important CSFs that have a positive impact on successful Lean Transformation on Greek public organizations/utilities are: Effective Communication, flexible Organizational Infrastructure, Customer Focus, Linking Lean to Suppliers, Business Plan and Vision, competent Change Management, Top Management Support and Commitment, Training and Education, as well as Selection of Staff. On the contrary, the existence of a bureaucratic Organizational Culture has a negative effect on successful integration of Lean Management. <strong>Limitations: </strong>Important limitations of this study are the utilization of a convenience sample and the strict focus on Greek public organizations operating in a competitive environment.展开更多

Based on data for the damage caused by four recent major earthquakes in Japan, we investigate the trends in the number of evacuees and evacuation centres after these disasters as well as the restoration processes for public utilities such as electricity, gas, water, and communication lines. We compare the restoration speeds and trends of the damaged infrastructure systems. We also propose various mathematical models to approximate the recovery trends using both evacuee-related data and damage recovery process data. These results can be used to design natural disaster mitigation policies not only in Japan, but also in other countries. The results of various statistical data analyses and mathematical modelling techniques are applied to provide policy suggestions.展开更多
