Abstract: In the Sudano-Sahelian areas of Africa droughts can have serious impacts on natural resources, and therefore land surface moisture is an important factor. Insufficient conventional sites for monitoring land surface moisture make the use of Earth Observation data for this purpose a key issue. In this study we explored the potential of using reflectance data in the Red, Near Infrared (NIR), and Shortwave Infrared (SWIR) spectral regions for detecting short term variations in land surface moisture in the Sahel, by analyzing data from three test sites and observations from the geostationary Meteosat Second Generation (MSG) satellite. We focused on responses in surface reflectance to soil- and surface moisture for bare soil and early to mid- growing season. A method for implementing detrended time series of the Shortwave Infrared Water Stress Index (SIWSI) is examined for detecting variations in vegetation moisture status, and is compared to detrended time series of the Normalized Difference Vegetation Index (NDVI). It was found that when plant available water is low, the SIWSI anomalies increase over time, while the NDVI anomalies decrease over time, but less systematically. Therefore SIWSI may carry important complementary information to NDVI in terms of vegetation water status, and can provide this information with the unique combination of temporal and spatial resolution from optical geostationary observations over Sahel. However, the relation between SIWSI anomalies and periods of water stress were not found to be sufficiently robust to be used for water stress detection.
Alcohol consumption patterns during transition and economic growth in Estonia: results from the 1996 and 2006 health interview surveys  [PDF]

Abstract: Aims: To investigate alcohol consumption patterns in Estonia in 1996, which represents the transition period after the collapse of the Soviet Union, and in 2006, which is characterized by economic growth. Methods: Data from all 25 – 64 year olds from the nationally representative 1996 and 2006 Estonian Health Interview Surveys were analysed. The frequency of alcohol consumption and heavy episodic drinking (HED) were examined. The odds ratios of at least weekly alcohol consumption and HED according to socio-demographic characteristics were calculated using logistic regression models. Results: In comparison with 1996, at least weekly alcohol consumption was nearly twice as high among men in 2006. No association between HED and the study year was found. Alcohol consumption was lower among respondents in the oldest age group. Weekly alcohol consumption was lower among non-Estonian men in both study years. HED was higher among non-Estonian men and women in 1996 but this difference disappeared in 2006. Weekly alcohol consumption was lower among less educated men in 1996 but not in 2006. No clear tendency in weekly alcohol consumption by education was found among women. HED was higher among less educated men in both study years; however, this association was weaker in 2006. While HED was not associated with education among women in 1996, an inverse relationship was found in 2006. Conclusions: The study confirmed that rapid societal changes had an effect on alcohol consumption patterns in Estonia. Estonia needs the implementation of a comprehensive alcohol policy to decrease harmful alcohol consumption in the whole society.

Taking Care of Digital Collections and Data: ‘Curation’ and Organisational Choices for Research Libraries
Inge Angevaare
Liber Quarterly : The Journal of European Research Libraries , 2008,
Abstract: This article explores the types of digital information research libraries typically deal with and what factors might influence libraries’ decisions to take on the work of data curation themselves, to take on the responsibility for data but market out the actual work, or to leave the responsibility to other organisations. The article introduces the issues dealt with in the LIBER Workshop ‘Curating Research’ to be held in The Hague on 17 April 2009 ( http://www.kb.nl/curatingresearch) and this corresponding issue of LIBER Quarterly.
