Long-term and large-scale multispecies dataset tracking population changes of common European breeding birds

Around fifteen thousand fieldworkers annually count breeding birds using standardized protocols in 28 European countries. The observations are collected by using country-specific and standardized protocols, validated, summarized and finally used for the production of continent-wide annual and long-term indices of population size changes of 170 species. Here, we present the database and provide a detailed summary of the methodology used for fieldwork and calculation of the relative population size change estimates. We also provide a brief overview of how the data are used in research, conservation and policy. We believe this unique database, based on decades of bird monitoring alongside the comprehensive summary of its methodology, will facilitate and encourage further use of the Pan-European Common Bird Monitoring Scheme results.publishedVersio

Ambivalent Stereotypes Towards Gendered Robots: The (Im)mutability of Bias Towards Female and Neutral Robots

Many studies have investigated the effect of robot genderedness on the attribution of gender stereotypes to a robot, often with mixed results. This paper aims to overcome some of the limitations of previous research. We adopted a mixed study design with stereotypical trait type (communion vs. agency) or task type (stereotypical female vs. stereotypical male) and robot genderedness (female vs. male vs. neutral) as within-subjects factors, and participant gender (men vs. women) as between-subjects factor. We asked participants to rate 24 robots (8 per category) in terms of their perceived communion, agency, and suitability for stereotypical female and male tasks. The results disclosed that female robots activate paternalistic stereotypes (higher communion than agency, higher suitability for female tasks than male tasks), while male robots do not. Moreover, they reveal that the ambivalence of these stereotypes is stronger in men than in women. Even more interestingly, our analyses showed that neutral robots activate paternalistic stereotypes in men and envious stereotypes (higher agency than communion) in women. This last finding is particularly relevant as it suggests that gender neutrality is not enough to safeguard robots from harmful biases

Models of (Often) Ambivalent Robot Stereotypes:: Content, Structure, and Predictors of Robots' Age and Gender Stereotypes

This study focused on investigating the content, structure, and predictors of robots' stereotypes. We involved 120 participants in an online study and asked them to rate 80 robots on communion, agency, suitability for female and suitability for male tasks. In line with the stereotype content model, we discovered that robots' stereotypes are described by two dimensions, communion and agency, which combine to form univalent (e.g., low communion/low agency), as well as ambivalent clusters (e.g., low communion/high agency). Moreover, we found out that a robot's stereotypical appearance has a role in activating stereotypes. Indeed, in our study, female robots featuring appearance cues socio-culturally associated with femininity (e.g., eyelashes or apparel) were perceived as more communal, and juvenile robots featuring appearance cues tapping into the baby schema (e.g., cartoony eyes) were perceived as more communal, less agentic, and less suited to perform tasks. Given the renowned relationship between stereotyping, prejudice and discrimination, the causal link between appearance and stereotyping we establish in this paper can help HRI researchers disentangle the relation between robots' design and people's behavioral tendencies towards them, including proneness to harm

Evaluation of head and neck cancer education at European dental schools

Aim: In Europe, approximately 150.000 patients are diagnosed with head and neck cancer annually. Dentists play an important role in prevention and detection at an early stage when survival rates are best. This study aims to evaluate content of head and neck cancer education curricula of European dental schools. Materials and Methods: A questionnaire, comprising 20 questions about content of curricula and teaching methods, was distributed to the deans of all 234 members of the Association for Dental Education in Europe. Results: The response rate was 24%. All dental schools included head and neck cancer screening practices in their curricula, two-thirds had their students perform this screening on all patients routinely and education was mostly divided over various courses (65%). A variation in content of education in screening practices and counselling patients about various risk factors was reported. Alcohol and tobacco use were included in most curricula as risk factors for head and neck cancer (98%), gastro-oesophageal reflux was less frequently included (41%). The human papillomavirus (HPV) as a risk factor for oropharyngeal cancer was included in 94% of curricula and 87% also contained education about strategies to discuss prevention of HPV-related cancer. No association was found between curricula containing strategies about discussing HPV-related cancer and inclusion of the HPV vaccine in national immunisation programmes. Conclusion: Head and neck cancer teaching programmes show a considerable variation across European dental schools. Development of a unified teaching programme suitable for all European dental schools seems warranted

Synergistic Effect of Feeding Time and Diet on Hepatic Steatosis and Gene Expression in Male Wistar Rats

Objective: Eating out of phase with the endogenous biological clock alters clock and metabolic gene expression in rodents and can induce obesity and type 2 diabetes mellitus. Diet composition can also affect clock gene expression. This study assessed the combined effect of diet composition and feeding time on (1) body composition, (2) energy balance, and (3) circadian expression of hepatic clock and metabolic genes. Methods: Male Wistar rats were fed a chow or a free-choice high-fat, high-sugar (fcHFHS) diet, either ad libitum or with food access restricted to either the light or dark period. Body weight, adiposity, and hepatic fat accumulation as well as hepatic clock and metabolic mRNA expression were measured after 5 weeks of the diet. Energy expenditure was measured using calorimetric cages. Results: Animals with access to the fcHFHS diet only during the light period showed more hepatic fat accumulation than fcHFHS dark-fed animals despite less calories consumed. In contrast, within the chow-fed groups, light-fed animals showed the lowest hepatic fat content, but they also showed the lowest caloric intake. Locomotor activity and heat production followed feeding times, except in the fcHFHS light-fed group. Hepatic clock and metabolic gene expression rhythms also followed timing of food intake. Yet, in the fcHFHS light-fed animals, clock gene expression appeared 3 hours advanced compared with chow light-fed animals, an effect not observed in the fcHFHS dark-fed animals. Conclusions: An fcHFHS diet consumed in the light period promotes hepatic fat accumulation and advances clock gene expression in male Wistar rats, likely because of a mismatch between energy intake and expenditure

Association of Antibiotic Resistance in Agricultural Escherichia coli Isolates with Attachment to Quartz▿

Surface water can be contaminated by bacteria from various sources, including manure from agricultural facilities. Attachment of these bacteria to soil and organic particles contributes to their transport through the environment, though the mechanism of attachment is unknown. As bacterial attachment to human tissues is known to be correlated with antibiotic resistance, we have investigated here the relationship between bacterial attachment to environmental particles and antibiotic resistance in agricultural isolates. We evaluated 203 Escherichia coli isolates collected from swine facilities for attachment to quartz, resistance to 13 antibiotics, and the presence of genes encoding 13 attachment factors. The genes encoding type I, EcpA, P pili, and Ag43 were detected, though none was significantly related to attachment. Quartz attachment was positively and significantly (P < 0.0038) related to combined resistance to amoxicillin/streptomycin/tetracycline/sulfamethazine/tylosin/chlortetracycline and negatively and significantly (P < 0.0038) related to combined resistance to nalidixic acid/kanamycin/neomycin. These results provide clear evidence for a link between antibiotic resistance and attachment to quartz in agricultural isolates. We propose that this may be due to encoding by the responsible genes on a mobile genetic element. Further exploration of the relationship between antibiotic resistance and attachment to environmental particles will improve the understanding and modeling of environmental transport processes, with the goal of preventing human exposure to antibiotic-resistant or virulent microorganisms
