Standard lessons from economics tell us that an externality creates inefficiency, and that this inefficiency can be removed by internalizing the externality. This papers considers how successfully these lessons can be extended to intergenerational externalities such as emissions of greenhouse gas. For intergenerational externalities, the standard lessons involve comparisons between states whose...

Received for publication 11 May 1979 and in revisedform 2 October 1979. 592 50% penetrant autosomal recessive model between the two types of families is compatible with a genetic dissimilarity between them. The high frequency ofthe Dw3 and Dw4 antigens, the Dw3/Dw4 genotype, and the decreased frequency of Dw2, however, indicate the existence of two or more important diabetic genetic factors ass...

©FSRH J Fam Plann Reprod Health Care 2010: 36(4) Summary The issue of gender is an essential feature of the provision of sexual and reproductive health services and policy formulation should be directed towards the needs of men as well as women. This approach is especially important for youth services, with an emphasis on personal relationships and the provision of condoms for safer sex. The vi...

Case Reports Case 1, a female child (IV, 3 in Pedigree) born on December 23, 1958, was noticed to have opaque corneae, of sufficient degree to prevent any estimate of the size of the pupils. There was corneal oedema but no appreciable abnormality of the corneal diameter. In the course of a few days the cornea of each eye had become obviously enlarged and a definite buphthalmos had become establ...

Aim: In this era of globalisation characterised with rapid spread and usage of Information Communication Technology (ICT) and the capacity to store personal information, the issue of information privacy is becoming an increasing concern. In this study, the attitude of Black South African Generation Y students towards information privacy in relation to loyalty card usage was examined. Method: A ...

The computation of all minimal transversals of a given hypergraph in output-polynomial time is a long standing open question known as the transversal hypergraph generation. One of the first attempts on this problem—the sequential method of Berge [Ber89]—is not output-polynomial as shown by Takata [Tak02]. In recent years, three new algorithms designed to improve the sequential method were publi...

The frequency of cloud detection and the frequency with which these clouds are found in the upper troposphere have been extracted from NOAA High Resolution Infrared Radiometer Sounder (HIRS) polar-orbiting satellite data from 1979 to 2001. The HIRS/2 sensor was flown on nine satellites from the Television Infrared Observation Satellite-Next Generation (TIROS-N) through NOAA-14, forming a 22-yr ...

Nuclei below the Z = 50 magic shell gap with A∼100 show a wide variety of structural phenomena. These include excellent examples of vibrational collectivity at low-spins, which give way to more rotational-like excitations with increasing angular momentum. In this paper we present recent results from an experiment performed at Yale to study the yrast evolution of states in 98,99Mo and 101,102Ru....

This study is an investigation of the work ethic of K-12 educators from Generation X and Baby Boom generations. Although much has been written about the baby boom generation, there have been few studies that investigated the work ethic of teachers born between 1946 and 1964 (Gribbin, 2003; Keller, 2002; Petty 2009; Petty 2010; Petty & Brewer, 2008). Additionally, there exists a teacher shortage...
