Non-bee insects are important contributors to global crop pollination

Wild andmanaged bees arewell documented as effective pollinators of global crops of economic importance. However, the contributions by pollinators other than bees have been little explored despite their potential to contribute to crop production and stability in the face of environmental change. Non-bee pollinators include flies, beetles, moths, butterflies, wasps, ants, birds, and bats, among others. Here we focus on non-bee insects and synthesize 39 field studies from five continents that directly measured the crop pollination services provided by non-bees, honey bees, and other bees to compare the relative contributions of these taxa. Non-bees performed 25-50% of the total number of flower visits. Although non-bees were less effective pollinators than bees per flower visit, they made more visits; thus these two factors compensated for each other, resulting in pollination services rendered by non-bees that were similar to those provided by bees. In the subset of studies that measured fruit set, fruit set increased with non-bee insect visits independently of bee visitation rates, indicating that non-bee insects provide a unique benefit that is not provided by bees. We also show that non-bee insects are not as reliant as bees on the presence of remnant natural or seminatural habitat in the surrounding landscape. These results strongly suggest that non-bee insect pollinators play a significant role in global crop production and respond differently than bees to landscape structure, probably making their crop pollination services more robust to changes in land use. Non-bee insects provide a valuable service and provide potential insurance against bee population declines.Peer Reviewe

Large expert-curated database for benchmarking document similarity detection in biomedical literature search

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency-Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.Peer reviewe

Percepção de professores de educação infantil sobre a inclusão da criança com deficiência

A educação infantil é importante para o desenvolvimento da criança com necessidades especiais. Nesse processo educacional, o professor e sua percepção de educação inclusiva são fatores primordiais. Este trabalho objetivou analisar a percepção de professores de educação infantil, que quanto à prática educativa atual, diferem em relação à presença de alunos com deficiências em seus ambientes de trabalho, sobre a educação da criança com deficiência na faixa etária de 3 a 6 anos. Foram sujeitos da pesquisa 12 professores de educação infantil divididos eqüitativamente em três grupos: de escolas especiais; de escolas comuns que trabalham com crianças com deficiências inseridas em suas classes e de escolas comuns que não possuem em suas classes crianças com deficiências. A coleta de dados foi realizada através de entrevistas semi-estruturadas, gravadas em fita cassete. Foi realizada análise de conteúdo e os dados mostraram que os professores vêem como a principal contribuição do processo de inclusão a socialização da criança com deficiências, restringindo-o, porém, a crianças com possibilidades de independência. Quanto à aprendizagem, acreditam que a criança com deficiência mental é a que encontra maiores dificuldades, contrariamente à com deficiência física. Ressaltam problemas com o espaço físico, recursos materiais e humanos e relativos à formação do professor. Pôde se concluir que é preciso possibilitar aos professores uma formação que abranja conhecimentos sobre as diferentes deficiências e as necessidades educacionais relativas a estas, propiciar a adequação do espaço físico e dos recursos materiais, além de assistência técnica específica.Early childhood education is important for the development of children with special needs. The teacher and his/her perception of inclusive education are essential factors throughout such educational processes. The present study aimed to analyze early childhood teacher's perception of the education of children with disabilities aged three and six years. Their perception of current educational practices is different due to the presence of special needs children in their working environment. Twelve childhood education teachers participated in this study and were equally divided into three groups: those from special schools; those from ordinary schools, who work with children with disabilities and those from ordinary schools who don't have children with disabilities in the classroom. The data were collected using tape recorded semi-structured interviews. Content analysis was performed. The data indicated that the teachers see the disabled children's socialization as the main contribution of the inclusive process, however, they deemed that inclusion should be restricted to children with possibilities of independence. As to the learning process, they expressed that children with intellectual disabilities had more difficulty than the ones with physical disability. Problems regarding physical space, material and human resources as well as teacher education were pointed out. It was concluded that the teachers need preparation not only regarding the understanding of various disabilities and the educational needs related to them but also about adequate physical space, material resources and specific technical assistance
