Maternal care provides antifungal protection to eggs in the European earwig

2014

Many insects raise their offspring on organic substrates or in the soil where microorganisms are abundant. Microbes may pose a serious threat to offspring development and survival by either decomposing food resources or directly infecting the offspring. Selection to cope with these effects may favor social defenses, for example, through forms of parental care that can limit or eliminate these threats to offspring fitness. In this study, we experimentally tested if maternal egg attendance in the European earwig Forficula auricularia has a function as a social defense against mold infection of eggs by manipulating exposure of eggs to mold spores and the presence of the mother in a fully facto…

Toxicological and bioactivity evaluation of blackcurrant press cake, sea buckthorn leaves and bark from Scots pine and Norway spruce extracts under a…

2021

Aqueous extracts from blackcurrant press cake (BC), Norway spruce bark (NS), Scots pine bark (SP), and sea buckthorn leaves (SB) were obtained using maceration and pressurized hot water and tested for their bioactivities. Maceration provided the extraction of higher dry matter contents, including total phenolics (TPC), anthocyanins, and condensed tannins, which also impacted higher antioxidant activity. NS and SB extracts presented the highest mean values of TPC and antioxidant activity. Individually, NS extract presented high contents of proanthocyanidins, resveratrol, and some phenolic acids. In contrast, SB contained a high concentration of ellagitannins, ellagic acid, and quercetin, exp…

Anxiety level and decision-making among Norwegian top-class soccer referees

2013

The purpose of this study was to examine the level of anxiety experienced by Norwegian top-class soccer referees while officiating, and to predict the level of anxiety according to refereeing level and perceived refereeing competence. Also investigated were referees' perceptions of how crowd noise and disturbance from players and/or coaches, failure (i.e. mistakes) in refereeing, and aggressive behaviour by players and/or coaches influence their decision-making when officiating. A total of 83 (response rate: 84.7%) referees (73 men and 10 women) aged 20–46 years (mean = 33.2 years) completed our questionnaire using SurveyXact, a web-based program for conducting electronic questionnaires. Th…

Lessons Learned from the German Registry for Acute Aortic Dissection Type A (GERAADA) and Expectations for the Future

2014

The German Registry for Acute Aortic Dissection type A (GERAADA) is a prospective observational clinical multicenter registry that was launched in 2006. With more than 2,500 patients included from over 50 recruiting centers it is—to our knowledge—the most representative register for acute aortic dissection type A (AADA) currently available. We examined mortality and post-operative events as well as the influence of various pre- and intraoperative factors on these endpoints. Among patients registered, 30-day mortality is 15.9 %. 13.4 % of patients experienced postoperatively a new neurological deficit and a total of 10.5 % of patients suffered from permanent neurological impairment 30 days a…

Responsabilité Sociale de l'Entreprise et pratiques de Gestion des Ressources Humaines

2006

As far as human resource management practices (HRM) are concerned, how do French companies respond to corporate social responsibility (CSR)? Are they eager to develop practices beyond the existing legal rules? To answer these questions, we present the results of an inquiry involving 106 HR managers who mainly belong to large manufacturing companies. Their statements, collected by questionnaire, are focused on a few "responsible" HRM practices: - Recruiting practices in favour of disabled or non skilled persons - Training practices promoting the access or the return to work - Communication practices encouraging the dialog between the managers and the employees. According to our results, the …

River ecosystems receive and process vast quantities of terrestrial organic carbon, the fate of which depends strongly on microbial activity. Variation in and controls of processing rates, however, are poorly characterized at the global scale. In response, we used a peer-sourced research network and a highly standardized carbon processing assay to conduct a global-scale field experiment in greater than 1000 river and riparian sites. We found that Earth’s biomes have distinct carbon processing signatures. Slow processing is evident across latitudes, whereas rapid rates are restricted to lower latitudes. Both the mean rate and variability decline with latitude, suggesting temperature constrai…

Archaeogenetics and Landscape Dynamics in Sicily during the Holocene: A Review

2021

The Mediterranean islands and their population history are of considerable importance to the interpretation of the population history of Europe as a whole. In this context, Sicily, because of its geographic position, represents a bridge between Africa, the Near East, and Europe that led to the stratification of settlements and admixture events. The genetic analysis of extant and ancient human samples has tried to reconstruct the population dynamics associated with the cultural and demographic changes that took place during the prehistory and history of Sicily. In turn, genetic, demographic and cultural changes need to be understood in the context of the environmental changes that took place…

The indigenous settlement of Monte Iato (western Sicily): an ethnoarchaeometric approach for outlining local Archaic ceramic productions

2021

AbstractAn ethnoarchaeometric approach has been followed to identify the textural and compositional characteristics of the ceramic pastes produced in ancient Iaitas/Ietas, an indigenous site located in western Sicily on Monte Iato, a few tens of kilometres from Palermo. This approach was primarily motivated by the lack of discovered Archaic kilns or production sites/workshops and the inability to identify reference groups. Raw clays were sampled in the territory of San Cipirello and San Giuseppe Iato (today’s municipalities both sited on the northern slopes of Monte Iato), together with representative historic tiles and bricks locally produced until fairly recently. Grain-size analysis and …
