This study analyzes online reader comments on top US newspapers’ stories related to former congressman, Anthony Weiner’s, August 2016 sexting scandal. Audience gatekeeping was seen through such discussion themes as gender bias and sexism, political scandals, and sex addiction. The analysis revealed that the majority of reader comments significantly diverged from the news topic, and many comments about US politicians were uncivil. Furthermore, online discussions “drowned out” newspapers’ intended message about Weiner’s inclusion of his toddler son into a sexually explicit selfie. This study argues that online commentary should not be perceived as a dichotomy—a negative or positive development, a contributor or preventer of public discourse—but rather as a continuum of citizen engagement.  相似文献

Average and advanced readers from the fourth and sixth grades read visually presented words as rapidly as possible. Target words were preceded by a related prime word, an unrelated word, or a neutral warning stimulus. Related trials constituted 75% of the word prime trials for half of the subjects in each group, and only 25% for the other half. All groups were sensitive to this proportion manipulation, showing only faster naming times for related targets in the 25% condition. In the 75% condition, subjects showed inhibition for unrelated targets, as well as facilitation for related targets. The results indicate that the ability to use context deliberately to facilitate word recognition reaches asymptote for the average reader by the sixth grade at the latest, and perhaps by the fourth. This ability does not appear to be one that shows further improvements at higher levels of reading skill. Some possible reasons for the discrepancies between this research and that using incomplete sentence contexts are considered.  相似文献

Public libraries today are undergoing significant transformations as well as interacting with patrons in new and different ways (Knight Foundation 2017). Part of this transformation is the way libraries are engaging entire families. Libraries are playing a stronger role than ever before in supporting families to promote children’s early literacy and reading skills (Celano and Neuman 2015; Nagle et al. 2016; Neuman and Celano 2010), stimulating adult learning (Boden and Tashijan 2015), creating initiatives to improve family health (Morgan et al. 2016), providing services to families with extreme challenges such as those experiencing poverty, homelessness, food insecurity, and incarceration (Holt and Holt 2010; Terille 2016), as well as becoming spaces for families, especially those who are recent immigrants, to build new relationships and social networks (Khoir et al. 2017; Vårheim 2014). Despite these efforts, few studies have specifically sought to understand the organizational dimensions that support family engagement within a library system and the potential that these efforts have in promoting children’s learning not only in the early years, but also into and throughout middle childhood and adolescence. Based on a yearlong study investigating the power of family engagement in public libraries, this article considers how libraries can begin to adopt a systemic approach to family engagement to further innovate the library space.  相似文献

Providing access to relevant biomedical literature in a clinical setting has the potential to bridge a critical gap in evidence-based medicine. Here, our goal is specifically to provide relevant articles to clinicians to improve their decision-making in diagnosing, treating, and testing patients. To this end, the TREC 2014 Clinical Decision Support Track evaluated a system’s ability to retrieve relevant articles in one of three categories (Diagnosis, Treatment, Test) using an idealized form of a patient medical record. Over 100 submissions from over 25 participants were evaluated on 30 topics, resulting in over 37k relevance judgments. In this article, we provide an overview of the task, a survey of the information retrieval methods employed by the participants, an analysis of the results, and a discussion on the future directions for this challenging yet important task.  相似文献

The Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Stanford‐Binet Intelligence Scale–Fourth Edition (SB‐IV), were administered to 20 gifted children and 20 non‐gifted children to examine the extent of the difference in IQ scores obtained on the two tests and whether order effects were present. Results show that the SB‐IV Composite Score was significantly higher than the WISC‐III Full Scale IQ for both groups. However, for the gifted group, unlike the non‐gifted group, this difference achieved significance only when the SB‐IV was administered first. When either IQ test was administered to the gifted students for the first time, without the confound of a learning influence, there was no significant difference in mean scores. However, when both tests were administered, it was found that the SB‐IV influenced the WISC‐III Full Scale IQ in a downward direction whereas the WISC‐III influenced the SB‐IV Composite Score in an upward direction. © 2002 Wiley Periodicals, Inc.  相似文献

The influence of disciplinary differences onself-perceived gains in critical thinking andcommunication skills were examined in terms of studentbackground characteristics, experiences in the major,and college experience variables. Academicdisciplines were categorized according to Biglan's(1973a) classification of single- and multiple-paradigmdisciplines. Although multigroup structural equationmodeling showed no differences between self-perceivedgains for single- and multiple-paradigm disciplines, theproposed theoretical model accounted for 13.5% and 25.3%of the variance in self-perceived gains in critical thinking and communication skills,respectively. The variable most highly associated withself-perceived gains was the quality of lower-divisioncourses in the major.  相似文献

The authors contend that erroneous conclusions concerning intraindividual strengths and weaknesses may result when comparing scaled scores on subtests of The Test of Reading Comprehension. Examination of scaled scores may seem to indicate that a given student has performed better on one subtest than on another when, in reality, the difference between the two scores is not statistically significant. The authors present a table in which statistically significant differences between subtest scaled scores are identified. Use of the table enables more precise determination of intraindividual strengths and weaknesses.  相似文献

Abstract

The aim of this study was to investigate spatiotemporal and kinematic changes between the initial acceleration, transition and maximum velocity phases of a sprint. Sagittal plane kinematics from five experienced sprinters performing 50-m maximal sprints were collected using six HD-video cameras. Following manual digitising, spatiotemporal and kinematic variables at touchdown and toe-off were calculated. The start and end of the transition phase were identified using the step-to-step changes in centre of mass height and segment angles. Mean step-to-step changes of spatiotemporal and kinematic variables during each phase were calculated. Firstly, the study showed that if sufficient trials are available, step-to-step changes in shank and trunk angles might provide an appropriate measure to detect sprint phases in applied settings. However, given that changes in centre of mass height represent a more holistic measure, this was used to sub-divide the sprints into separate phases. Secondly, during the initial acceleration phase large step-to-step changes in touchdown kinematics were observed compared to the transition phase. At toe-off, step-to-step kinematic changes were consistent across the initial acceleration and transition phases before plateauing during the maximal velocity phase. These results provide coaches and practitioners with valuable insights into key differences between phases in maximal sprinting.  相似文献
