Body weight provides insights into the feeding strategy of swarming bats.
2010
Temperate bat species that hibernate in underground sites are known to visit hibernacula in late summer where they perform an activity known as "swarming". We analysed trends in body mass-to-forearm ratio - the body condition index (BCI) - to investigate whether bats arrive at swarming sites following intensive nocturnal feeding. In a two-year study, Myotis daubentonii, M. brandtii and M. dasycneme were captured by mist-net at one swarming site from late July until early October. In late summer, the BCIs of captured males, females and subadult bats were positively correlated to the time of their capture during the night. In September, adult bats had higher BCIs than in late summer and the B…
An Optimized Design of Choice Experiments: A New Approach for Studying Decision Behavior in Choice Task Experiments
2014
In this paper, we present a new approach for the optimal experimental design problem of generating diagnostic choice tasks, where the respondent's decision strategy can be unambiguously deduced from the observed choice. In this new approach, we applied a genetic algorithm that creates a one-to-one correspondence between a set of predefined decision strategies and the alternatives of the choice task; it also manipulates the characteristics of the choice tasks. In addition, this new approach takes into account the measurement errors that can occur when the preferences of the decision makers are being measured. The proposed genetic algorithm is capable of generating diagnostic choice tasks eve…
Target analysis of primary aromatic amines combined with a comprehensive screening of migrating substances in kitchen utensils by liquid chromatograp…
2015
An analytical strategy including both the quantitative target analysis of 8 regulated primary aromatic amines (PAAs), as well as a comprehensive post-run target screening of 77 migrating substances, was developed for nylon utensils, using liquid chromatography-orbitrap-high resolution mass spectrometry (LC-HRMS) operating in full scan mode. The accurate mass data were acquired with a resolving power of 50,000 FWHM (scan speed, 2 Hz), and by alternating two acquisition events, ESI+ with and without fragmentation. The target method was validated after statistical optimization of the main ionization and fragmentation parameters. The quantitative method presented appropriate performance to be u…

Aerobic Metabolism: Benefits from an Oxygenated World
2010
In the preceding chapter, we have emphasized the dangers that the advent of dioxygen presented to the existing anaerobic organisms, and the ways they evolved to deal with the problems. However, this is only part of the story and were it to have ended here, we and the world we know would not exist. What happened instead was quite remarkable; for life seized upon an opportunity presented by the presence of free dioxygen to become many-fold more efficient in extracting energy from foodstuffs. As we shall see, this aerobic, oxidative metabolism opened in turn a multitude of new opportunities for growth and diversification.
Spain: commercialization drives public debate and precaution
2000
Since the commercialization of genetically modified (GM) crops and foods in Spain in 1996, these products have become a topic of public concern and conflict. Several important social protagonists from science, industry and civil society have become involved in the public debate. The conflicts have influenced the regulation, improving its precautionary content, in response to social pressures in Spain and elsewhere in Europe. As Spain has become the primary cultivator of GM crops in the European Union, commercial cultivation there has been scientifically monitored for possible long-term environmental effects. Regulators have also asked industry to cease using antibiotic-resistant marker gene…
The role of civil society organisations in European responsible research and innovation
2018
EC policy reveals a strong conviction that CSO’s main function in EU-funded research and innovation projects is to take care of the ‘societal perspective’, which would not be adequately represented otherwise. With this, CSOs are supposed to be the main advocates of RRI in project consortia and are supported by all kinds of EC policy measures to fulfil this role. This conviction is not only problematic due to definition problems concerning CSO as such. Empirical data about the role of CSOs in high-tech/high-innovation research projects and the distribution of RRI activities among consortia members reveal that the role of CSOs is much more multi-faceted (data providers, providers of access to…
Changing Policy Environments in Europe and the Resilience of the Third Sector
2020
Contains fulltext : 202754.pdf (Publisher’s version ) (Closed access) In the article, we analyse the impact of changing policy environments on the development of the third sector in Europe. Based on the results of systematic comparative research in eight European countries (Austria, Croatia, France, Germany, the Netherlands, Poland, Spain and the UK), we identify commonalities and differences. In a three-step analysis, we examine policy changes, effects on the third sector and responses by third sector organizations (TSOs) in the social domain. Overall, the third sector in Europe has proven resilient. However, not only have public and private funding decreased, the process for acquiring suc…
Factors influencing inclusion in digestive cancer clinical trials: A population-based study
2015
Inclusion in a randomized therapeutic trial represents an optimal therapeutic strategy.To determine the influence of demographic characteristics and deprivation on the enrolment of patients in digestive cancer clinical trials.Between 2004 and 2010, 4632 patients were recorded by the Burgundy Digestive Cancer Registry. According to a balancing score, the 136 patients included in a clinical trial were matched with 272 patients who met the eligibility criteria for trials. Deprivation was measured by the ecological European deprivation index. A conditional multivariate logistic regression was performed.Patients aged over 75 years were significantly less likely to be included in clinical trials …
Estrategia de revascularización invasiva en el síndrome coronario sin elevación del segmento ST. El debate continúa
2009
Revascularization strategy in the setting of non-ST-segment acute coronary syndromes remains a controversy. Evidence obtained from clinical trials, generally performed in selected patients, reveals heterogeneous and insufficient results when a routine invasive revascularization strategy and a conservative one are compared. The conflicting results among trials are due to differences in: a) baseline characteristics; b) methodology and protocols applied and; c) objectives and outcomes definitions. Although present guidelines recommend that a routine invasive strategy should be used in high risk non-ST-segment elevation acute coronary syndromes, there is no consistent evidence that supports thi…
