Air Temperature Distribution and Energy-balance Modelling of a Debris-covered Glacier

Near-surface air temperature is an important determinant of the surface energy balance of glaciers and is often represented by a constant linear temperature gradients (TGs) in models. Spatiotemporal variability in 2 m air temperature was measured across the debris-covered Miage Glacier, Italy, over an 89 d period during the 2014 ablation season using a network of 19 stations. Air temperature was found to be strongly dependent upon elevation for most stations, even under varying meteorological conditions and at different times of day, and its spatial variability was well explained by a locally derived mean linear TG (MG–TG) of −0.0088°C m−1. However, local temperature depressions occurred over areas of very thin or patchy debris cover. The MG–TG, together with other air TGs, extrapolated from both on- and off-glacier sites, were applied in a distributed energy-balance model. Compared with piecewise air temperature extrapolation from all on-glacier stations, modelled ablation, using the MG–TG, increased by <1%, increasing to >4% using the environmental ‘lapse rate’. Ice melt under thick debris was relatively insensitive to air temperature, while the effects of different temperature extrapolation methods were strongest at high elevation sites of thin and patchy debris cover.

The Effect of Wasta on Business Conduct and HRM in Jordan

Despite rapid globalisation, boom in multinational business and increasing interest in international human resource management (IHRM) generally, research on developing countries in the Middle-East is limited. A three year PhD research project seeks to begin to fill this gap by studying the effect of Jordanian culture on the transfer of western recruitment and selection (R&S) frameworks into Jordan. This paper opens up an investigation into a cultural concept at the heart of management and human resource management (HRM) in Jordan: ‘wasta’. Wasta is a concept that springs from tribalism; favouritism based on family and tribal relations. For multinational organisations this presents a challenge in balancing the western idea of fairness, equal opportunities and diversity and the local system based on favouritism. We argue that the perceived benefits of wasta cannot match the moral case for a merit based model.
