Developing ethical geography students? The impact and effectiveness of a tutorial-based approach

This paper explores the effectiveness of a tutorial-based approach in supporting the development of geography undergraduates’ ethical thinking. It was found that overall the intervention had a statistically significant impact on students’ ethical thinking scores as assessed using a Meta-Ethical Questionnaire. The initiative led to a convergence of scores, having a bigger impact on those who had a relatively low score prior to the intervention. Interestingly, the approach had the biggest impact on students who self-identified as physical geographers. Unlike some previous research, there was little evidence of difference between male and female students.     

Kites of AlUla County and the Ḥarrat ʿUwayriḍ, Saudi Arabia

A comprehensive remote sensing survey of AlUla County in north-west Saudi Arabia has revealed 32 examples of the ancient, stone-built animal traps known as ‘kites’. Noting that most (27) are located on the Ḥarrat ʿ Uwayriḍ, a satellite survey of parts of that lavafield outside of AlUla County was undertaken, identifying a further 175 kites. These show commonalities with ‘V-shaped’ kites previously identified in mountainous areas along the western extents of the Arabian Shield in the Sinai Peninsula, Negev Desert and south-west Saudi Arabia. A study of the form and placement of these kites in their ecological and geological contexts suggests that they are representative of a distinct complex, exhibiting sophisticated morphological adaptations to target specific games over similar terrain.     

Spatial Diffusion of the HIV/AIDS Epidemic: Modeling Implications and Case Study of AIDS Incidence in Ohio

This paper extends a compartmental epidemiological model for HIV transmission and AIDS incidence to include hierarchical and expansion spatial diffusion. An implication of the resultant model is that hierarchical diffusion causes the large infection growth rates of densely populated areas at the top of the central places hierarchy to “chain” down and dominate small local growth rates during the exponential-growth phase of the epidemic. Also, hierarchical diffusion causes a high transient growth rate in the first few years of a local epidemic. The spatial compartmental model fits observed AIDS incidence spatial diffusion patterns in Ohio reasonably well.
