We develop natural language processing techniques to identify the creation and impact of new technologies in the population of U.S. patents. We validate the new techniques and their improvement over traditional metrics based on patent classification and citations in two case-control studies. First, we collect patents linked to awards such as the Nobel prize and the National Inventor Hall of Fame. These patents likely cover radically new technologies with a major impact on technological progress and patenting. Second, we identify patents granted by the United States Patent and Trademark Office but simultaneously rejected by both the European and Japanese patent office. Such patents arguably lack novelty or cover small incremental advances over prior art and should have little impact on technological progress. We provide open access to code, data, and new measures for all utility patents granted by the USPTO up to May 2018 (see https://zenodo.org/record/3515985, DOI: 10.5281/zenodo.3515985). 相似文献

The mean age of identification for autism spectrum disorder (ASD) occurs during the months before children enter kindergarten. The incidence and prevalence of “autistic behaviors” in the general population are not fully understood, however, census-matched studies of these behaviors have yielded important new data. As children presenting with behaviors characteristic of ASD enter school, school psychologists are increasingly faced with the assessment and determination of individuals with disabilities improvement act (IDEIA) eligibility, often with students yet to be formally diagnosed with ASD. In many US states, a clinical diagnosis of ASD is not required for a child's eligibility to be served under the category of other health impaired as autism. Nor does a diagnosis of ASD automatically qualify a student as eligible under IDEIA. Eligibility hinges on educational impact. This article briefly reviews the current state of knowledge as it relates to understanding and evaluating children with suspected ASD in the schools, offers a framework for assessment, and discusses a set of proposed guidelines to assist in effectively utilizing assessment data in the development of individualized education plan goals. 相似文献

This study investigated age-related differences in maturity, physical and functional characteristics and playing performance in youth Australian Football (AF). Young male players (n = 156) were recruited from 12 teams across 6 age groups (U10–U15) of a recreational AF club. All players were tested for body size, maturity and fitness. Player performance was assessed during a match in which disposals (kicks and handballs) and their effectiveness were coded from a video recording and match running performance measured using Global Positioning System. Significant main effects (P < 0.01) for age group were observed for age, years to peak height velocity, body mass, height, 20 m sprint, maximal speed over 20 m, vertical jump, 20 m multistage shuttle run, match distance, high-speed running distance, peak speed, number of effective disposals and percentage of effective disposals. Age-related differences in fitness characteristics (speed, lower body power and endurance) appeared to transfer to match running performance. The frequency in which players disposed of the football did not differ between age groups, however the effectiveness of each disposal (i.e., % effective disposals) improved with age. Match statistics, particularly those that evaluate skill execution outcome (i.e., effectiveness), are useful to assess performance and to track player development over time. Differences between age groups, and probably variability within age groups, are strongly associated with chronological age and maturity. 相似文献

Between the years 1993 and 2000, the W. K. Kellogg Foundation sponsored the Comprehensive Community Health Models (CCHMs) Initiative in three Michigan counties. CCHMs was comprised of three closely related community initiatives carried out in the midst of a failed national health care reform effort and the continued penetration of managed care arrangements into many health care systems. This experimental initiative set out to test the hypothesis that traditional healthcare system animosities and exclusionary practices could be overcome by stakeholder participation in an ongoing, structured, collaborative dialogue about improving access to health services. In the process of collecting data through surveys, interviews, content analysis, and observation, we were struck by the occurrence of several overarching tensions that we perceive to exist in our data. The present article elucidates five such tensions and suggests how third parties such as communication researchers, evaluators, and practitioners can facilitate community health improvement initiatives and better their own data interpretation by acknowledging and understanding these tensions. 相似文献

Our understanding of the transition from school to work has traditionally been underpinned by a three-stage model. This is one in which the first stage is a preparatory one, where the focus is on school, followed by a second transition stage and ending in a third stage, the successful entry to work. This is a model that has been challenged by work from the ‘cultural studies’ school but still informs much contemporary work. The study of freelance dancers’ entry into work reveals a very different experience of the transition. Rather than a sequence of experiences of school, preparation for work and then entry into established employment, the dancer’s experience is one of coterminus experiences of work, vocational training and family life that can start before the entry into primary education. This represents a serious challenge to the three-stage model as a general model for conceptualising transitions. Using the experience of the dancers and building on the work of Becker and Wyn, this paper explores how the concept of belonging points the way forward towards a more comprehensive conceptualisation of the transition. 相似文献

The effects of obstetrical medication on neonatal behavior were studied using a sample of Israeli infants from medicated and nonmedicated mothers. Few significant behavioral differences were detected in the first month of life, and there was no difference in Bayley Infant Scale performance at 3 months of age. Comparative analyses using samples of American and Uruguayan infants and additional data from other studies of American newborns led to the conclusion that light levels of obstetrical medication do not appear to have significant effects on neonatal behavior. However, this may well be qualified by some initial population differences, by the measurements commonly used in the studies reviewed, and possibly by critical cutoff points dividing the levels of medication that will and will not affect neonatal behavior. 相似文献

An investigation into the impact of predictive text use upon the literacy skills of primary school, secondary school and university cohorts was conducted over the course of a year. No differences in use of text abbreviations (‘textisms’) were found between predictive text users and nonusers. However, secondary school children who used predictive text made more genuine spelling errors than nonusers. Predictive text was related to use of some specific grammatical violations in school‐age children's text messages but was not related overall to the tendency to make grammatical errors when texting. University students, however, made significantly fewer grammatical errors in their text messages when they used predictive text. Over the course of a year, predictive text use was variable for all age groups. Consistency of predictive text use was unrelated to grammatical understanding, spelling or orthographic processing for primary and secondary school cohorts. Predictive text use was negatively related to morphological awareness for adult participants. 相似文献

Connecting the public to concepts in science, technology, engineering, and mathematics (STEM) is an essential for technological advancement and inspiring future scientists, impacting both the communicator and the audience's understanding of scientific topics. Without proper communication of scientific knowledge, acceptance and implementation of new technologies can be hindered. Additionally, increasing public awareness about current scientific issues through STEM engagement permits more informed policy and consumer choices, especially in the field of food science where many new food technologies are met with initial resistance by the consuming public. Here, we describe an event that introduced topics in food science to the nonexpert public, including K‐8th grade participants and their adult caregivers in an informal learning environment. This program consists of six activities that collectively introduce three areas in food science: food chemistry, food microbiology, and process engineering. Protocols are provided for each activity including a materials list (with the option to scale up or down according to event duration, event space allowances, and number of participants), learning objectives and discussion points that are adaptable to different age groups, event spaces, or budgets. Each activity has a participatory component to ensure both audience member and instructor engagement. A program designed for food science communication empowers young scientific minds to better understand complex scientific topics and could inspire them to envision a possible career in STEM fields, with the additional benefit of providing graduate students an exciting medium through which they may practice their science communication skills, potentially benefiting not only their personal academic and professional skills but also broader societal needs. 相似文献

How to Study Effectively was probably the first distance learning course in the UK to help students to acquire learning skills. It has consistently attracted large numbers of students. Sam Rouse has tutored the course for the whole of its life and this paper reports the result of an evaluation he recently carried out. Samples of three student groups, all enrolled in 1972, were asked for their views on the course after a ten year gap. A group of'normal'enrollers is compared with two more special groups, one of TUC sponsored students and one of intending ordinands in the Church of England. Why did they enrol? How many assignments did they complete? What did they think of the course? What differences if any has it made to their lives? The paper concludes with three case studies of students, one from each group. The full report, And Having Studied Effectively , is published by the National Extension College. 相似文献
