Current phonological awareness assessment procedures consider only the total score a child achieves. Such an approach may result in children who achieve the same total score receiving the same instruction even though the configuration of their errors represent fundamental knowledge differences. The purpose of this study was to develop a tool for phonological awareness error classification and explore the types of errors made by 215 grade one children from low socioeconomic backgrounds on a phonological awareness test. Twenty-one distinct errors were identified and classified into eight categories. The most frequently occurring error category was Additions followed by Segmentations, Substitutions, Insertions, Repetitions, Omissions, Reversals, and Multiple Errors. Examination of a subsample of study participants who were classified as high and low reading performers revealed differences in the both the degree and type of errors exhibited. Low reading performers exhibited significantly more Insertion, Omission, Segmentation, and Substitution errors. Knowledge of child errors has the potential to enhance understanding and interpretation of child test performance and subsequent instructional recommendations.  相似文献

Objective:Systematic reviews and other evidence syntheses, the pinnacle of the evidence pyramid, embody comprehensiveness and rigor; however, retracted data are being incorporated into these publications. This study examines the use of retracted publications in the field of pharmacy, describes characteristics of retracted publications cited by systematic reviews, and discusses factors associated with citation likelihood.Methods:Using data from Retraction Watch, we identified retracted publications in the pharmacy field. We identified all articles citing these retracted publications in Web of Science and Scopus and limited results to systematic reviews. We classified the retraction reason, determined whether the citation occurred before or after retraction, and analyzed factors associated with the likelihood of systematic reviews citing a retracted publication.Results:Of 1,396 retracted publications, 283 were cited 1,096 times in systematic reviews. Most (65.0%) (712/1096) citations occurred before retraction. Citations were most often to items retracted due to data falsification or manipulation (39.2%), followed by items retracted due to ethical misconduct including plagiarism (30.4%), or concerns about or errors in data or methods (26.2%). Compared to those not cited in systematic reviews, cited items were significantly more likely to be retracted due to data falsification and manipulation, were published in high impact factor journals, and had longer delays between publication and retraction.Conclusions:Further analysis of systematic reviews citing retracted publications is needed to determine the impact of flawed data. Librarians understand the nuances involved and can advocate for greater transparency around the retraction process and increase awareness of challenges posed by retractions.  相似文献

An increase in salivary leukocytes may contribute to the exercise-induced increase in salivary antimicrobial proteins (AMPs). However, exercise-induced changes in salivary leukocytes have not been studied. The purpose of the study was to describe salivary leukocyte changes with exercise. Participants (= 11, 20.3 ± 0.8 years, 57.2 ± 7.6 ml kg?1 min?1 peak oxygen uptake ((VO) ?2peak), 11.1 ± 3.9% body fat) ran for 45 min at 75% of VO2peak. Stimulated saliva (12 mL) was collected pre- and immediately post exercise. Saliva was filtered through a 30 µm filter before analysis of leukocytes (CD45+), granulocytes (CD45+CD15+), monocytes (CD45+CD14+), T-cells (CD45+CD3+), and B-cells (CD45+CD20+) using flow cytometry. Saliva was analysed for Lysozyme (Lys) using ELISA. Exercise did not alter any leukocyte subset. The major constituent of leukocytes pre-exercise were granulocytes (57.9 ± 30.3% compared with monocytes: 5.1 ± 2.7%, T-cells: 17.1 ± 8.9%, B-cells: 12.1 ± 10.2%) (P < 0.05). In a subset of = 6, Lys secretion rate increased after exercise (pre: 5,170 ± 5,215 ng/min; post: 7,639 ± 4,140 ng/min) (P < 0.05). Exercise does not result in increased granulocytes, but does increase Lys. Further, these data suggest that an increase in salivary leukocytes is not needed to increase Lys.  相似文献

In this article, Caitlin Howlett offers a critical framework for understanding the limits of prohibitive and individually oriented sexual harassment policies in academia through a discussion of melodrama. Howlett draws on the work of Linda Williams, Emma Goldman, and Carole Vance in arguing that such sexual harassment policies participate in melodrama and thus fail to address the structural or institutional conditions that allow for sexual harassment. She then turns to the work of Sara Ahmed to examine what is at stake in this failure, before concluding that this understanding of sexual harassment policies points to their insufficiency and inadequacy within the academy.  相似文献

We explored 30 Black Kindergarten‐2nd grade students' spoken narratives around pages of their science journals that the children selected as best for showing them as scientists. Because in all narratives, space–time relationships play an important role not only in situating but also in constituting them, we focused on such relationships using Bakhtin's (1981) construct of chronotopes. Our chronotopical analysis aimed at fleshing out the temporal and spatial features that were present in the children's journal pages, and in the children's ways of talking both about these features and about being scientists. Our goal was to better understand ways in which African‐American children identify with science and scientists in particular contexts: an interview with an adult who had visited their class throughout that year and a class where they were offered various opportunities to engage with science. Using six cases that maximized the variety of understandings we could develop vis‐à‐vis our research question, we show how the children's narratives were filled with differing space–time relationships in which the children found ways to showcase their agency. Thus, we provide insights into how the children authored relationships with science and scientists, negotiated the past with the present and possible future, and contextualized their narratives within various time‐spaces that had meaning for them. Moreover, multiple people populated the children's chronotopes and became intertwined with the space–time relationships that underlined their conceptions of themselves vis‐à‐vis science and scientists. Despite the varied conceptions of science and scientists that the children portrayed, their narratives communicated a high level of confidence in being able to do science and be scientists, and initiative in learning. The children's narratives were filled with hope, “able‐ness,” knowledge, affect, and possibility. These findings point to several considerations for practice. © 2012 Wiley Periodicals, Inc.

Background:Concerns over scientific reproducibility have grown in recent years, leading the National Institutes of Health (NIH) to require researchers to address these issues in research grant applications. Starting in 2020, training grants were required to provide a plan for educating trainees in rigor and reproducibility. Academic medical centers have responded with different solutions to fill this educational need. As experienced instructors with expertise in topics relating to reproducibility, librarians can play a prominent role in providing trainings, classes, and events to educate investigators and trainees, and bolstering reproducibility in their communities.Case Presentations:This special report summarizes efforts at five institutions to provide education in reproducibility to biomedical and life sciences researchers. Our goal is to expand awareness of the range of approaches in providing reproducibility services in libraries.Conclusions:Reproducibility education by medical librarians can take many forms. These specific programs in reproducibility education build upon libraries'' existing collaborations, with funder mandates providing a major impetus. Collaborator needs shaped the exact type of educational or other reproducibility support and combined with each library''s strengths to yield a diversity of offerings based on capacity and interest. As demand for and complexity of reproducibility education increases due to new institutional and funder mandates, reproducibility education will merit special attention.  相似文献

Globally, school systems are pressed to engage in large-scale school improvement. In the United States and other countries, school district central offices and other local governing agencies often engage with external organizations and individuals to support such educational change efforts. However, initiatives with external partners are not always productive. We draw on the idea of absorptive capacity to present a conceptual framework for understanding when and under what conditions partnerships are likely to foster district learning and support change efforts. We contend that prior knowledge, communication pathways, strategic knowledge leadership, and resources to partner are preconditions for a district central office’s absorptive capacity, and we identify the features of the external partner that likely matter for productive partnering. We argue that the relationship between district absorptive capacity and features of the partner is mediated by the nature of the interactions between district and partner, with likely consequences for organizational learning outcomes. For researchers, this framework serves as a tool for understanding how a district central office can learn from an external partner for educational improvement efforts. For school district leaders and external partners, this framework provides a structure for thinking strategically about when and under what conditions a partnership is likely to be productive.  相似文献

This paper compares the concept of mixed faith/cultural education in Northern Ireland and Israel. It is primarily concerned with the processes that these ‘integrated’ schools adopt in their quest to improve relations between divided ethnic groups. Drawing on qualitative data collected in two mixed religion primary schools in each jurisdiction the paper shows that the schools' existing cultural norms act as important mediating influences on the way that inter‐group relationships are constructed. The paper concludes that attention needs to be paid to both the policy context and the culture if contact initiatives are to be successful.  相似文献

The performance of deaf children with cochlear implants was assessed using measures standardized on hearing children. To investigate nonverbal cognitive and sensorimotor processes associated with postimplant variability, five selected sensorimotor and visuospatial subtests from A Developmental Neuropsychological Assessment (NEPSY) were compared with standardized vocabulary, reading, and digit span measures. Participants were 26 deaf children, ages 6-14 years, who received a cochlear implant between ages 1 and 6 years; duration of implant use ranged from 3 to 11 years. Results indicated significant correlations between standard scores on the Design Copying subtest of the NEPSY and standard scores on vocabulary comprehension, reading, and digit span measures. The results contribute to our understanding of the benefits of cochlear implantation and cognitive processes that may support postimplant language and academic functioning.  相似文献
