Key fundamental aspects for mapping and assessing ecosystem services: Predictability of ecosystem service providers at scales from local to global

How an apparent static and ordered landscape condition in social ecological landscapes (SELs), can be made sustainable in terms of maintenance and improvement of the provision of ecosystem services (ESs) in face of unpredictable disturbance and change? Our contribution to the Mapping and Assessment of Ecosystem Services (MAES) working group is to advance some recommendations on how to approach the dynamic analysis of complex adaptive systems to improve ecosystem resilience, habitat connectivity and the delivery of ESs. We show exemplary cases where we utilize the NDVI provided by remote sensing to evaluate land cover transformations and processes and ES provisioning. We focus on NDVI because it allows the supply of information on net primary production, i.e., the energetic foundation of nearly all ecosystems and that provides the basis of most of ESs. The use of spectral entropy, and nonlinear analysis of spatial temporal dynamics to investigate trajectory predictability of SELs provide very useful insight into the dynamics of SELs and can assist in the characterization of the links between land cover patterns with ecological processes to support more reliable assessments and accountings of ESs

Dynamical chiral symmetry breaking and confinement with an infrared-vanishing gluon propagator?

We study a model Dyson-Schwinger equation for the quark propagator closed using an {\it Ansatz} for the gluon propagator of the form \mbox{$D(q) \sim q^2/[(q^2)^2 + b^4]$} and two {\it Ans\"{a}tze} for the quark-gluon vertex: the minimal Ball-Chiu and the modified form suggested by Curtis and Pennington. Using the quark condensate as an order parameter, we find that there is a critical value of $b=b_c$ such that the model does not support dynamical chiral symmetry breaking for $b>b_c$. We discuss and apply a confinement test which suggests that, for all values of $b$, the quark propagator in the model {\bf is not} confining. Together these results suggest that this Ansatz for the gluon propagator is inadequate as a model since it does not yield the expected behaviour of QCD.Comment: 21 Pages including 4 PostScript figures uuencoded at the end of the file.

Ethnic variation in the prevalence of depression and anxiety in primary care: A systematic review and meta-analysis.

Primary care plays a key role in the detection and management of depression and anxiety. At present it is not clear if the prevalence of depression and anxiety in primary care differs between migrants and ethnic minorities (MI) and natives and ethnic majorities (MA). A systematic review and a meta-analysis of studies comparing the prevalence of depression and anxiety in MI and MA in primary care were performed. Studies were identified by searching MEDLINE, PsychINFO, EMBASE and through hand-search. We included 25 studies, most of which had a relatively small sample size. Significant variations were found in the prevalence of anxiety and depression across studies. Pooled analyses were carried out for 23 studies, based on random-effects models. Pooled RR of depression and anxiety in MI were 1.21 (95% CI 1.04-1.40, p=0.012) and 1.01 (95% CI 0.76-1.32, p=0.971), with high heterogeneity (I\ub2=87.2% and I\ub2=73%). Differences in prevalence rates among studies can be accounted for by inclusion criteria, sampling methods, diagnostic instruments and study design. Further research on larger samples and with culturally adapted instruments is needed to estimate the prevalence of depression and anxiety in MI seeking help for these disorders

Risk Factors for Lung Cancer in the Province of Lecce: Results from the PROTOS Case–Control Study in Salento (Southern Italy)

In the province of Lecce (southern Italy), a higher incidence of lung cancer (LC) among men compared to regional and national data was reported. In a sub-area in the center of the province (cluster area), the incidence and mortality for LC was even higher. PROTOS is a case–control study aimed at investigating possible risk factors for LC in the province area. A total of 442 patients with LC and 1326 controls matched by sex and age living in the province of Lecce for at least 10 years were enrolled and georeferenced; they filled in a questionnaire with their personal information and exposures. For each risk factor, an Odds Ratio adjusted for all the other variables was calculated. The risk of LC increased with excessive use of alcohol in women, for those subjects with a family cancer history, for each increase in pack/year of cigarettes, for men more exposed considering the industrial district in the cluster area, and for those using pesticides in agriculture without wearing personal protective equipment. The higher incidence of adenocarcinoma in both sexes suggests that, in addition to cigarette smoking, concurrent exposures to other environmental, occupational, and life-style factors may play a role in increased cancer risk and should be more deeply explored
