Abstract

In this paper we consider the effects of certain capital market imperfections on portfolio choice problems. We show that as a result of these imperfections, the distribution functions of rates of return may depend on portfolio allocation, thus leading to non‐convexities and consequently to patterns of specialisation rather than diversification.

Abstract

Purpose

There appears to be a puzzle associated with the observation that individuals both donate and volunteer to charity. If the purpose of a giving individual is to maximize the effect of his/her donation, then he/she should give as effectively as possible. This implies that an individual should donate either time or money but not both. Yet, simultaneous volunteering and donating money is extremely common. Indeed, it may be viewed as the rule rather than the exception. This paper aims to offer a solution to this puzzle.

Design/methodology/approach

This theoretical paper models giving behavior by individuals and takes into account the disutility of volunteer and income related work.

Findings

By modeling the difference between an individual's volunteer and income‐related work, it can be understood why individuals' giving behavior of donating money and volunteering.

Research limitations/implications

Future research should test these findings empirically.

Originality/value

Theoretical contribution to our understanding of giving behavior as to why individuals donate money and time even if is not economically efficient to do both.

Abstract

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

Abstract

Purpose

In spite of the fact that the health, mental, and educational benefits of physical activity are well documented, information is still lacking regarding the physical activity patterns in Israeli society. The purpose of the present study is to shed light on the changes of physical activity practices between the years 1992‐2008 and to analyze the main reasons for such changes.

Design/methodology/approach

A survey was conducted among 501 adults (ages 18‐69) representing the Jewish Hebrew‐speaking population of Israel.

Findings

The percentage of Israelis who engaged in physical activity more than doubled between 1992 and 2008. Almost 56 percent of Israelis took part in some activity on a regular basis in 2008.

Originality/value

This investigation of some of these factors uncovers a cultural transformation as well as demographic, global, and cognitive processes, all of which affected and reflected upon physical activity in Israeli society during that period.

Abstract

Purpose

This review paper seeks to conceptualise childhood obesity through clinical, operational, and financial procedures. It informs multiple disciplines about: the trajectory of paediatric obesity and current recommendations; the trends in the clinical, administrative/policy and financial worlds of paediatric obesity; and discusses commonly misunderstood collaborative terms.

Design/methodology/approach

The paper is based on analysis of national and international policy documents and research papers in the field.

Findings

Paediatric obesity treatment teams, programmes, and providers could all benefit from a document that bridges the disciplines of medicine, other professions, and financial management. A family centred, multidisciplinary approach is necessary at all stages of obesity treatment care and the three‐world model discussed is helpful in achieving this. The clinical, operational, and financial aspects of the service need to be integrated in a way that reduces the barriers to accessing services.

Originality/value

The paper combines perspectives from different service sectors: clinical, operational, and financial. To facilitate interdisciplinary cooperation, it offers common definitions of terms that often have different meanings for those involved.
