GEOCHEMICAL AND MINERALOGICAL FINGERPRINTS OF THE SEDIMENTS SUPPLY AND EARLY DIAGENETIC PROCESSES IN THE BIZERTE LAGOON (TUNISIA)
2016
International audience; The Bizerte Lagoon (Tunisia) functions as a sedimentation environment characterized by receiving allochthonous sediments mainly transported by the Ben Hassine, Rharek and Guenich streams, as well as marine sediments from the Mediterranean Sea. It is subjected to significantenvironmental changes due to the natural and anthropic influences altering the natural patterns of circulation, extraction and/or deposition of mineralogical materials. The aim of this investigation is to analyze the sediments supply and early diagenetic processes in Bizerte Lagoon. Thephyicochemical parameter of the sediment pore water, as well as their texture, mineralogical composition (X-Ray di…
Drivers of peat accumulation rate in a raised bog: impact of drainage, climate, and local vegetation composition
2017
We used variation partitioning to assess the relative importance of drainage, climate and local vegetation composition for the development of a raised bog. As a case study we selected Teici (Teici) Bog in Latvia (north-east Europe). Explanatory variables together explained 74 % of the variation in peat accumulation and only the residue of 26 % remained unexplained. Our study showed that the local vegetation composition and dominant Sphagnum species significantly influence peat accumulation rates. The results of linear models revealed that, under natural conditions, minor drainage and even strong drainage of the peat is associated with a positive growth balance of the system. However, draina…
Good Quality Care for Cancer Patients Dying in Hospitals, but Information Needs Unmet: Bereaved Relatives’ Survey within Seven Countries
2021
Abstract Background Recognized disparities in quality of end‐of‐life care exist. Our aim was to assess the quality of care for patients dying from cancer, as perceived by bereaved relatives, within hospitals in seven European and South American countries. Materials and Methods A postbereavement survey was conducted by post, interview, or via tablet in Argentina, Brazil, Uruguay, U.K., Germany, Norway, and Poland. Next of kin to cancer patients were asked to complete the international version of the Care Of the Dying Evaluation (i‐CODE) questionnaire 6–8 weeks postbereavement. Primary outcomes were (a) how frequently the deceased patient was treated with dignity and respect, and (b) how well…
Evaluation of 10 pesticide residues in oranges and tangerines from Valencia (Spain)
2006
Abstract One hundred and sixteen orange and tangerine samples from an agricultural cooperative of the Valencian Community (Spain) were analyzed for bitertanol, carbendazim, hexythiazox, imazalil, imidacloprid, methidathion, methiocarb, pyriproxyfen, thiabendazole, and trichlorfon by liquid chromatography–mass spectrometry (LC–MS) after a conventional multiresidue extraction procedure. Of 52 samples that contained pesticide residues, carbendazim was detected in 27 (51.9%) in the concentration range of 0.02–0.04 mg kg−1, hexythiazox in 22 (42.3%) in the concentration range of 0.02–0.05 mg kg−1, imazalil in 8 (15.0%) in the concentration range of 0.02–1.2 mg kg−1, imidacloprid in 5 (9.6%) in a…
Can we be satisfied with our football team? Evidence from spanish professional football.
2009
This article assesses the sporting performance of Spanish professional football teams at competition level, namely, League, King’s Cup, and European competitions (Champions League and Union of European Football Associations [UEFA] Cup). Then, the gap between the result obtained by a team at the end of a season and that expected according to its potential is used as a proxy of the degree of satisfaction that fans should feel: the narrower the gap the greater the level of satisfaction. Regarding methodology, Data Envelopment Analysis techniques and directional distance functions are used. Results reveal that most teams perform rather differently across competitions, the lower average performa…

Register data in sample allocations for small-area estimation
2018
The inadequate control of sample sizes in surveys using stratified sampling and area estimation may occur when the overall sample size is small or auxiliary information is insufficiently used. Very small sample sizes are possible for some areas. The proposed allocation based on multi-objective optimization uses a small-area model and estimation method and semi-collected empirical data annually collected empirical data. The assessment of its performance at the area and at the population levels is based on design-based sample simulations. Five previously developed allocations serve as references. The model-based estimator is more accurate than the design-based Horvitz–Thompson estimator and t…
Viral tunes:changes in musical behaviours and interest in coronamusic predict socio-emotional coping during COVID-19 lockdown
2021
AbstractBeyond immediate health risks, the COVID-19 pandemic poses a variety of stressors, which may require expensive or unavailable strategies during a pandemic (e.g., therapy, socialising). Here, we asked whether musical engagement is an effective strategy for socio-emotional coping. During the first lockdown period (April–May 2020), we surveyed changes in music listening and making behaviours of over 5000 people, with representative samples from three continents. More than half of respondents reported engaging with music to cope. People experiencing increased negative emotions used music for solitary emotional regulation, whereas people experiencing increased positive emotions used musi…

This article stems from a gender-specific examination of migration decision-making and remittance behavior as a proxy for the creation of gendered transnational spaces when faced with macro-economi...
Last interglacial temperature seasonality reconstructed from tropical Atlantic corals
2016
Abstract Reconstructions of last interglacial (LIG, MIS 5e, ∼127–117 ka) climate offer insights into the natural response and variability of the climate system during a period partially analogous to future climate change scenarios. We present well preserved fossil corals (Diploria strigosa) recovered from the southern Caribbean island of Bonaire (Caribbean Netherlands). These have been precisely dated by the 230Th/U-method to between 130 and 120 ka ago. Annual banding of the coral skeleton enabled construction of time windows of monthly resolved strontium/calcium (Sr/Ca) temperature proxy records. In conjunction with a previously published 118 ka coral record, our eight records of up to 37 …
