Queries submitted to search engines can be classified according to the user goals into three distinct categories: navigational, informational, and transactional. Such classification may be useful, for instance, as additional information for advertisement selection algorithms and for search engine ranking functions, among other possible applications. This paper presents a study about the impact of using several features extracted from the document collection and query logs on the task of automatically identifying the users’ goals behind their queries. We propose the use of new features not previously reported in literature and study their impact on the quality of the query classification task. Further, we study the impact of each feature on different web collections, showing that the choice of the best set of features may change according to the target collection. 相似文献

This paper provides evidence of the effects of adult literacy on individuals’ income and employability in Brazil based on information obtained from the monthly employment survey (PME). The OLS results indicate that after controlling for observable characteristics, there is a 21.25% increase in wages for individuals who become literate; however, there is no significant impact on employability. Moreover, the findings show an 8.1% increase in the probability of being employed in the formal sector. We also explore the longitudinal structure of the dataset to control for unobservable fixed characteristics of individuals. The fixed-effects estimators show smaller effects compared to the OLS estimators. We find that literacy has a 4.4% effect on wages and a 4.3% impact on the probability of being formally employed. The effects are significantly different from zero. 相似文献

ABSTRACTInclusion of students with disabilities in general education settings has been an international focus for over two decades. In the US, federal laws [e.g. Individuals with Disabilities Education Improvement Act (IDEIA). 2004. H.R. 1350, 108th Congress] mandate access to the general education curriculum for all students, including those with disabilities. These mandates codify a philosophical orientation of least restrictive environment, within a free appropriate public education, while explicitly requiring evidence-based practices. The policies support and protect inclusive practices for individuals with emotional and behavioural disabilities, yet the state of the empirical literature is unknown. A review is needed to provide an overview of the research and reveal the breadth of the literature. To this end, scoping review methodology was used to map the state of the literature. This particular approach is recommended for topics with myriad and complex definitions and issues, as is the case with inclusive education. Results map six themes (professional and student experience, strategy effectiveness, policy and programmes, perception of influencing factors, teacher training, teacher knowledge) and reveal several gaps in the literature. Recommendations are made for systematic review, meta-analyses, and individual studies to address the gaps in the literature. 相似文献

This paper examines perceptions of roles and responsibilities in primary and secondary initial teacher education following a sustained period of increase in the involvement of schools. The paper reports findings from a survey of higher education staff, school-based mentors and student teachers, which sought information about their perceptions of roles and responsibilities. A postal survey was followed up by telephone interviews. We found broad levels of agreement between all three partners in the training process and across primary and secondary phases. We found no evidence of a wish on the part of schools to assume greater responsibility for training student teachers. All three parties involved in the survey were able to articulate clearly areas of student professional development where they see complementary roles for school and higher education. 相似文献

The effects of running with or without shoes on injury prevention have been extensively studied, and several investigations have assessed biomechanical differences between them. However, findings are not consensual and further insights on biomechanical load associated with differently shod or barefoot conditions may be needed. This study aimed to observe if habitually shod marathon runners show acute alterations when running barefoot or with minimalist shoes, and to determine whether the running kinematical adaptations of wearing minimalist shoes were similar to barefoot running. Twelve male marathon runners ran on the treadmill at their average marathon pace in different footwear conditions: habitual running shoes, minimalist shoes, and barefoot. High-resolution infrared cameras and visual 3D software were used to assess kinematic data. The following parameters were studied: foot strike angle, cycle time, stance time, normalized stride length, hip, knee, and ankle angular position at initial contact, and their respective range-of-motion (ROM) during stance phase. Contrary to the expectations, it was found that highly trained habitually shod elite marathon runners changed their lower limb kinematic pattern both when running barefoot or wearing minimalist shoes. Minimalist shoes showed a trend towards intermediate biomechanical effects between running with and without shoes. 相似文献

This article considers international ice hockey from 1947 through the Squaw Valley Olympics in 1960. International hockey in these years dramatised important Cold War issues and offered useful insight into interaction among Americans, Canadians, Russians and Czechoslovaks. National programmes and styles of play reflected their nation states; hockey served simultaneously as both cultural diplomacy and psychological warfare. Czechoslovakia's powerhouse programme was purged for political reasons, while Prague officials tried to use Soviet hockey success to claim legitimacy for communism. The Soviets' communist-influenced ‘collective hockey’ achieved stunning success: the USSR national team started playing only in 1947 but was competitive with the world's best amateurs by 1954. Rules governing ‘amateurism’ were susceptible to manipulation, especially by communist regimes, further aiding Soviet progress. Canada remained the strongest power, but many of its best players were openly professional, hindering its efforts to stay on top. In 1948, US hockey demonstrated the messiness of an open society when two teams arrived in St Moritz claiming to represent the USA. After that, though, American players compiled a record in 1952, 1956 and 1960 that showed that the USA – not Canada, not the USSR – was the strongest nation in Olympic hockey. 相似文献

The author of this paper has just graduated from one of our great American seminaries. He seriously questions whether the education he received there has given him the best preparation for his future work in the ministry. His question is so pertinent that it calls for further exploration. The Editor has invited comment from a seminary graduate of one year standing, from a graduate of fifteen years standing, and from the heads of two seminaries which are particularly interested in preparing men for the ministry. Their comments follow immediately after the article. In the nature of the case, the author and the seminary would better remain anonymous. 相似文献

ABSTRACTNurturing students’ continuous learning is a current trend in the higher education agenda. Curricula and academic contents should enable students to take part in stimulating learning experiences, as well as promoting both developing and training opportunities in the course of their lives and careers. Despite the relevance given to lifelong learning in the educational system, there are still some open questions: how this concept is understood and put into practice by higher education institutions? The paper aims to analyse the conceptions of lifelong learning as reflected on the learning outcomes proposed in a sample of study programs. A qualitative methodology and a data-driven approach are adopted to explore the content of the learning outcomes proposed in 10% of total study programs submitted to quality accreditation, since 2009. Generally, results reveal that higher education institutions are committed to the lifelong learning paradigm, particularly in master and PhD degrees. Students are expected to ‘invest in personal and professional development through life’, to ‘develop learning competences through life’, as well as to ‘foster lifelong learning’. This study provides a better understanding of the range of perspectives and the relevance given to lifelong learning as a valuable learning outcome. 相似文献
