Different trends of neighboring populations of Lesser Kestrel: Effects of climate and other environmental conditions

2019

The sensitivity of population trends to the climate and environment is generally considered a species-specific trait. However, evidence that populations may show different responses to the climate and environmental conditions is growing. Whether this differential sensitivity may arise even among neighboring populations remains elusive. We compared the trends of two neighboring populations of the Lesser Kestrel Falco naumanni, using data from a 12-year survey of 158 colonies in Sicily, Italy; the two populations inhabiting a lowland and an highland area, respectively. Population trends were modeled through the TRIM algorithms implemented in R (package rtrim). A reversed U-shaped population t…

Comment on "Estimating average annual per cent change in trend analysis"

2010

We discuss some issues relevant to paper of Clegg and co-authors published in Statistics in Medicine; 28, 3670-3682. Emphasis is on computation of the variance of the sum of products of two estimates, slopes and breakpoints.

Capturing methodological trends in mobile communication studies

2013

This study investigates methodological trends in mobile communication studies. The articles published over the past 20 years in five journals (Communication Research, Journal of Communication, Journal of Computer-Mediated Communication, New Media & Society, and Information, Communication & Society) are analysed. The results show that the quantitative and qualitative studies have increased while theoretical accounts have remained few. The quantitative approach is the most applied. The studied articles reflect a structural problem of science communication that stems from the lack of cumulativity of scientific results and cross-national analyses and from the standard length of articles that po…

Climate change of Benin for the period 1950-2010 and its impact on surface water.

2016

6 pages; International audience; In West Africaand Benin in particular, variability / climate change affects the availability of surface water resources. Thus,this study aims to analyze the rainfall field of Benin from the fifty three (53) meteorological stations from 1950to 2010 and to detect the rainfall amounts and the average temperature of six synoptic stations and thehydrometric stations of Niger river in, Benin, Pendjari, Ouémé, Mono and Couffo. From the analysis a trend ofdeclining precipitation and of rising temperatures have been highlighted. This decrease is more pronounced inthe Sudanese area (north of 8 ° N) and in the sub-equatorial area (south of 8 ° N). This decrease of prec…

Mean speed in professional cycling: No evidence of decline

2014

Abstract The aim of this article was to evaluate the mean speed progression of the three major cycling stage races in order to empirically establish whether excellent in performance in professional cycling is to some extent correlated with the trend of blood doping and anti-doping throughout more than a century of official cycling competitions. We retrieved data about the mean speed of the winners of the Tour de France, Giro d’Italia and Vuelta a Espana, since their beginning. A linear correlation has then been calculated between the years and the mean speed in km/h for each single major cycling stage race, as well as for the mean speed of the winners of the three major cycling stage races …

Africa ad portas? : Italiens Migrationspolitik

2010

Through police co-operation, re-admission agreements, and setting up of detention camps, Italy’s immigration policy tries to delocalise border controls between Europe and North Africa. Italian immigration quotas and development aid should induce countries of origin and transit of migrants to tighten their border controls and cooperate with Italy. Development aid is used by the EU in order to exert pressure on other countries, whereas Libya for instance uses transiting refugees as a diplomatic weapon. On the other hand, relations between Italy and North African countries do not focus on human rights violations taking place in some of these countries.
