A STRUCTURAL MODEL OF THE DEMAND FOR COLLEGE ATTENDANCE IS DERIVED FROM THE THEORY OF COMPARATIVE ADVANTAGE AND RECENT STATISTICAL MODELS OF SELFSELECTION AND UNOBSERVED COMPONENTS. ESTIMATES FROM NBER-THORNDIKE DATA STRONGLY SUPPORT THE THEORY.

You might be interested in some of the things we are doing or attempting to accomplish within the Superior Court Judges' Association. Only one of our seven standing committees, that on judges' retirement, deals exclusively with matters that are peculiarly of interest to the judges themselves. The other committees—those on rules, juvenile delinquency, public institutions, improvement of the adminstration of justice, uniformity of dignity and procedure, and legislation—are concerned with, as their names imply, many different subjects of vital importance to the state and of interest to its citizens.

Environmental Systems Engineering and Economics emphasizes the application of optimization, economics, and systems engineering to problems in environmental resources management. This senior level/graduate textbook introduces optimization theory and algorithms that have been successful in resolving water quality and groundwater management problems. Both linear programming and nonlinear optimization are presented. Multiobjective optimization and the linked simulation-optimization (LSO) methodology are also introduced. The basic principles of economics and engineering economics are also discussed to provide a framework for economic decision making. This text contains numerous example problems. Case studies are presented that address water resources management issues in the north China plain, the control of saltwater intrusion in Jakarta, Indonesia, and groundwater resources management in the Yun Lin basin, Taiwan

Purpose- This paper investigates how mobile phones can be used to support women's entrepreneurship in Arab countries. The objective is to explore new ways to close the gender gaps in terms of entrepreneurship in these countries. Design/methodology/approach- The methodology used in this research is an in-depth analysis of the existing literature and recent reports on women's entrepreneurship and on the adoption and use of mobile phones in Arab countries. Findings- The findings of this research indicate that female Arab entrepreneurs are interested in using mobile phones. However, they have not yet realised the full potential of mobile technology in empowering them beyond its basic use. Several challenges facing women's entrepreneurship in the Arab countries were identified. Mobile phones can be used to overcome these challenges. Research limitations/implications- This research is based on the collection and analysis of secondary data rather than primary data to support the findings. Practical implications- There is a need for collaboration between telecommunication companies operating in the Arab region and government initiatives to build a solid environment in which female Arab entrepreneurs can operate. Originality/value- This research provides new insights and recommendations for reducing the gender gaps in terms of entrepreneurship by using new and improved techniques to address women's needs for economic independence. This will also increase the profit gained by the telecommunication companies operating in Arab countries and bring additional income to this region

PurposeTo consider the extent to which regimes of performance measurement in the public sector are fit for purpose, and the likely outcomes for public services and public sector workers of such performance measurement systems.Design/methodology/approachThe article considers four key issues: the context and content of performance measurement in the public sector, the specific examples of health care and higher education, the limitations of performance measurement systems, and the likely outcomes of performance measurement systems.FindingsCurrent systems of performance measurement in the public sector are unlikely to have a significant influence on improving services. The most likely outcomes of these systems is further commodification of services and deprofessionalisation of public sector workers.Originality/valueThe article builds on established literature and offers a systematic metaphor‐driven critique of performance management in the public sector, and discusses the implications of this.
