Beach safety education for primary school children

Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus.     

Happiness,income and poverty

There is considerable evidence from a variety of sources to suggest that well-being is a function of relative income. These findings have been used to explain the Easterlin Paradox, whereby a rise in income for all does not lead to a rise in average happiness in a country (even though the cross section relationship between income and happiness is positive). This relativity of utility has led to calls for policy to focus away from GDP. I here first discuss some of the evidence that well-being is indeed relative in income, but then consider two relatively little-analysed issues to suggest that there may continue to be a role for GDP per capita in happiness-based policy: the inequality of subjective well-being, and the specific case of those in income poverty.     

Medical Malpractice Liability and Physician Migration

This paper uses national data on individual physicians and two control groups to provide evidence on the extent to which each of five medical malpractice reforms impacts the decision to move one's medical practice to another state. We find robust evidence that states that have implemented noneconomic damage caps experience less out-migration of physicians than states that do not have these reforms. In addition, we find some evidence that joint and several liability reforms and patient compensation funds also impact the migration decisions of physicians.     

Strategic planning of complex economic systems ∗

A major drawback of conventional models of the behavior of economic systems (and derived tools for policy intervention) is that the desire for tractability leads generally to a high degree of abstraction from reality. This article suggests an alternative, and arguably complementary, approach which engages specifically with economic complexity. The technique used is one of interactive spatial modelling over long time periods where the principle economic agents base decisions on incomplete heuristic information. For illustrative purposes the model has been calibrated on the basis of Senegalese data for 1981–91 and broad generic equations presented. The article argues that such a methodological approach holds out considerable advantages for strategic planning of sustainable economic systems. In particular it permits the direct engagement of noneconomic disciplines and client stakeholders in the planning process.

Abstract

We consider an optimal dynamic control problem for an insurance company with opportunities of proportional reinsurance and investment. The company can purchase proportional reinsurance to reduce its risk level and invest its surplus in a financial market that has a Black-Scholes risky asset and a risk-free asset. When investing in the risk-free asset, three practical borrowing constraints are studied individually: (B1) the borrowing rate is higher than lending (saving) rate, (B2) the dollar amount borrowed is no more than K > 0, and (B3) the proportion of the borrowed amount to the surplus level is no more than k > 0. Under each of the constraints, the objective is to minimize the probability of ruin. Classical stochastic control theory is applied to solve the problem. Specifically, the minimal ruin probability functions are obtained in closed form by solving Hamilton-Jacobi-Bellman (HJB) equations, and their associated optimal reinsurance-investment policies are found by verification techniques.     

Running on the spot? A review of twenty years of research on the management of human resources in comparative and international perspective

Research using a comparative and international perspective on the management of human resources is examined, drawing on articles published in leading human resource management, management/organizational behaviour and related social science journals between 1977 and 1997. In total a little under 2 per cent of the articles under review focused on the management of human resources in a comparative and international perspective. The largest group of these articles was comparative in nature (44 per cent), followed by those with an international perspective (35 per cent). A smaller number adopted a combined approach (17 per cent) and a few were separately classified as foreign national studies (4 per cent). Over time, there has been some progress made in terms of the number of articles published and the scope of topics covered. However, many of the articles displayed similar shortcomings to those noted in earlier reviews of cross-national management/organization studies: in particular, an over-reliance on a small number of primarily Anglo-Saxon countries, a lack of a longitudinal perspective, a loose specification of culture, an ethnocentric bias and a frequent failure to explain observed differences and similarities.     

INVESTMENT PERFORMANCE OF COMMON STOCKS IN RELATION TO INSIDER OWNERSHIP

In this paper, the authors empirically examine whether corporations with high degrees of insider ownership enjoy superior returns compared with firms with more diffuse ownership. In addition, the authors evaluate the effects of insider ownership on security returns in relations to the well-known effects of size and earnings yield (or price-earnings) ratios. Results indicate that, in addition to Basu's price-earnings effect, insider ownership is a new statistically significant variable that is associated with abnormal returns. This return anomaly might occur because the market pays an inadequate price for top managements' equity ownership, a firm-specific fundamental variable that has a theoretical foundation in agency theory.     

The demography of micro-states

There are two types of micro-states, islands and mainland ones. Except for a few islands very close to the coast, most of the insular micro-states are demographically very different from the rest of the Third World. Their death-rates are lower, their birth-rates lower, and the propensity of their populations to migrate to developed countries higher. It is argued here that these differences are based on other social and economic differences, which can be summarized by saying that such states are more Westernized. They were part of the European maritime system at a time when the West did not have the economic strength to penetrate continental areas to the same extent. On the whole they retained colonial links longer.
