No full textA hyperspectral view of the North Sea
No full textOn the 16th of June 2003 a CASI hyperspectral airborne remote sensing campaign took place above the Southern North Sea, just offshore of Oostende. In coincidence with the airborne overpasses seaborne measurements of water leaving reflectance and water quality parameters were performed. In addition nearsimultaneous satellite imagery are available. This paper describes the analysis of the airborne data. The CASI data have been atmospherically corrected using the software WATCOR which is based on the radiative transfer code MODTRAN and takes into account atmospheric and air/water interface effects. Two different approaches for atmospheric information retrieval were tested. In the first approach aerosol information and visibility are estimated from sun photometer measurements combined with MODTRAN radiative transfer simulations. The second method is based on an adapted dark-target approach to estimate the visibility. The results of both methodologies are comparable. The data are subsequently geometrically corrected with PARGE. A semi-analytical approach is used to retrieve the concentration of the water constituents: for chlorophyll determination a bio-optically modeled red/NIR band ratio algorithm is applied to the data; to quantify the Suspended Particulate Matter a single band NIR algorithm is used. The results of these semi-analytical methods were compared to an analytical approach where the water quality parameters are retrieved using a matrix inversion of the Gordon reflectance model
Outsider status: stigma and discrimination experienced by gay men and African people with HIV
No full textIn recent years there has been an increasing amount of international-level policy and research about the negative impact that HIV-related stigma and discrimination have on the well-being of people with HIV and on prevention (Aggleton & Parker 2002, DeBruyn 2002, Nyblade 2003, UNAIDS/WHO 2003, United Nations 2001). It is clear that stigma and discrimination relating to HIV infection are persistent problems for those who have been diagnosed. Evidence gathered in the UK demonstrates that the majority of people living with HIV report the effects of stigma and discrimination in a range of settings (see Scott 2001 for a detailed review). Sigma’s own work investigating the experiences of people living with HIV in the UK has found that just under a quarter experienced discrimination within the previous year while accessing services, social settings, and in public (Weatherburn et al. 2002). Moreover, a study focussing on African people living with HIV in the UK (Weatherburn et al. 2003) revealed that over one third had experienced problems with discrimination in the previous year. This same study revealed that just under half of African people with HIV had not revealed their diagnosis to anyone they lived with, two thirds had not told their employers and a quarter had not told their GP. There is little question that people’s concern about disclosure of their diagnosis bears a direct relationship to their concern that doing so will bring about damaging consequences.
Although the prevalence and impact of stigma and discrimination relating to HIV in the UK is clear, there is little qualitative research that explores the operation of stigma and discrimination as processes and seeks to describe the nature of the relationship between stigma, discrimination and reduced health outcomes (although see Elam, 2004). Case studies and policy reports point to the role of government policy, political leadership and social environments in either worsening or ameliorating the negative effects of stigma and discrimination (Atrill et al. 2001, Kinniburgh et al. 2001, Fortier 2003). This report presents the findings of a study which explores how stigma and discrimination contribute to reduced health and well-being for the two largest groups of people living with HIV in the UK: African migrants and Gay and Bisexual men. In order to do so, it is necessary to critically consider the ways in which stigma and discrimination are theorised and described

No full textABSTRACTIn situ corrosion testing and in situ monitoring of the near field chemistry are performed as part of the Belgian experimental program for the qualification of an overpack material for long term HLW containment in deep clay formations. Several test facilities are now in operation and some of the first experimental data are presented and discussed in terms of the program objectives.</jats:p
Hyperspectral airborne remote sensing of the Belgian coastal waters
No full textOn the 16th of June 2003 a CASI (Compact Airborne Spectrographic Imager) hyperspectral airborne remote sensing campaign took place above the Southern North Sea, just offshore of Oostende. In coincidence with the airborne overpasses seaborne measurements of water leaving reflectance and water quality parameters were performed. In addition near-simultaneous satellite imagery are available. This paper deals with the analysis of the airborne data. The CASI data have been atmospherically corrected using the in-house software WATCOR which is based on the radiative transfer code MODTRAN-4 and takes into account atmospheric and air/water interface effects. The data are subsequently geometrically corrected with PARGE. A semi-analytical approach is used to retrieve the concentration of the water constituents: for chlorophyll determination a biooptically modelled red/NIR band ratio algorithm is applied to the data; to quantify the Suspended Particulate Matter a single band NIR algorithm, calibrated for the Belgian coastal waters is used. The results of these semi-analytical methods were compared to an analytical approach where the water quality parameters are retrieved from the subsurface irradiance reflectance spectra using a least square determination of chlorophyll-a (CHL), suspended particulate matter (SPM) and colored dissolved organic matter (CDOM) and requires as input the inherent optical properties (IOPs) of (specific) absorption and backscattering of the water constituents
