Risk factors for speech delay of unknown origin in 3-year-old children     

Campbell TF  Dollaghan CA  Rockette HE  Paradise JL  Feldman HM  Shriberg LD  Sabo DL  Kurs-Lasky M 《Child development》2003,74(2):346-357

One hundred 3-year-olds with speech delay of unknown origin and 539 same-age peers were compared with respect to 6 variables linked to speech disorders: male sex, family history of developmental communication disorder, low maternal education, low socioeconomic status (indexed by Medicaid health insurance), African American race, and prolonged otitis media. Abnormal hearing was also examined in a subset of 279 children who had at least 2 hearing evaluations between 6 and 18 months of age. Significant odds ratios were found only for low maternal education, male sex, and positive family history; a child with all 3 factors was 7.71 times as likely to have a speech delay as a child without any of these factors.  相似文献   

Investigating the Validity of the Australian Early Development Index     

Sally A. Brinkman  Sven Silburn  David Lawrence  Sharon Goldfeld  Mary Sayers  Frank Oberklaid 《Early education and development》2007,18(3):427-451

This article aims to contribute to the ongoing evaluation of the Australian Early Development Index (AEDI) by investigating its construct and concurrent validity with a subsample of 642 children aged 4 to 5 years drawn from the Longitudinal Study of Australian Children (LSAC). Construct validity was examined by considering the theoretical consistency of the network of correlations between the AEDI subconstructs and the independently reported multimethod measures of early learning skills and development collected contemporaneously by the LSAC. Concurrent validity was examined by assessing the extent to which children who were “developmentally vulnerable” on the AEDI domains corresponded with the LSAC outcome indices classification of children as “developmentally at risk.” Moderate to large correlations were observed between each of the AEDI domains and subconstructs when compared to analogous teacher-rated LSAC measures, with lower levels of association observed for parent-rated LSAC measures. Concurrent validity was explored; however, with no criterion measure with which to assess the AEDI, findings are inconclusive prior to predictive validity assessment. Future waves of the LSAC will collect information on the children's abilities at school and developmental outcomes, enabling further interpretation of these concurrent and construct validity findings by triangulation and predictive validity analyses.  相似文献   

Library Study Behaviors in the Age of Ubiquitous Mobile Devices: An Observational Study in Four Academic Libraries     

Amy Catalano  Lawrence Paretta  Claudia McGivney  Tara King 《The Reference Librarian》2014,55(4):328-342

In this study, researchers observed student study behaviors in the libraries of four post-secondary institutions. In all, 2,773 observations were made. This research replicates and expands an earlier study and addresses its limitations. The results of a logistic regression test indicate whether students had a mobile device readily available and where students chose to study in the library best predicted whether they demonstrated a study, as opposed to a non-study, behavior. Specifically, if students were found in quiet study or computer areas, they were more likely to be performing study behaviors. This research has implications for library stakeholders making decisions about the use of library space. Most importantly, this research demonstrates that library spaces are widely used for diverse purposes.  相似文献   

Anatomical Sciences Education Vol. 4, Issue 5, 2011 Cover Image     

Charleen M. Moore  Constance Lowe  Jane Lawrence  Penelope Borchers 《Anatomical sciences education》2011,4(5)

Drawing session from an art and anatomy workshop for medical students at the University of Texas Health Science Center at San Antonio and art students at the University of Texas at San Antonio. A current trend in medical education is to integrate aspects of the humanities into the medical school curriculum. In this issue of ASE, Dr. Charleen Moore and her colleagues describe an art and anatomy workshop that uses drawing exercises to increase observational skills, to foster the development of humanistic sensitivities, and to emphasize the emotional aspects of dealing with mortality.

Referential Labeling Can Facilitate Phonetic Learning in Infancy     

H. Henny Yeung  Lawrence M. Chen  Janet F. Werker 《Child development》2014,85(3):1036-1049

All languages employ certain phonetic contrasts when distinguishing words. Infant speech perception is rapidly attuned to these contrasts before many words are learned, thus phonetic attunement is thought to proceed independently of lexical and referential knowledge. Here, evidence to the contrary is provided. Ninety‐eight 9‐month‐old English‐learning infants were trained to perceive a non‐native Cantonese tone contrast. Two object–tone audiovisual pairings were consistently presented, which highlighted the target contrast (Object A with Tone X; Object B with Tone Y). Tone discrimination was then assessed. Results showed improved tone discrimination if object–tone pairings were perceived as being referential word labels, although this effect was modulated by vocabulary size. Results suggest how lexical and referential knowledge could play a role in phonetic attunement.  相似文献   

To stay or not to stay: retention of Asian international faculty in STEM fields     

Janet H. Lawrence  Sergio Celis  Hee Sun Kim  Sarah Ketchen Lipson  Ximeng Tong 《Higher Education》2014,67(5):511-531

The present study identifies characteristics of individuals and work settings that influence Asian international faculty members’ intentions to continue their employment in US research universities. Given the demand for researchers in science, technology, engineering and mathematics fields (STEM), the higher rate of turnover among untenured faculty, and the replacement costs associated with turnover in STEM, the sample is limited to assistant professors employed in these areas. Multinomial regression analyses are conducted to identify variables that “pull” and “push” uncertain faculty toward intentions stay and leave their current institutions. The results suggest that faculty who are more satisfied with time available for research and those who express stronger organizational commitment are more likely to say they will stay. Those dissatisfied with the fairness of work evaluations and believe tenure decisions are not merit-based, are more likely to say they will leave.  相似文献   

Explorations of a Paradox in Curriculum Control: Resistance to Open-ended Science Inquiry in a School for Self-directed Learning     

J. Lawrence Bencze  Maurice Di Giuseppe 《Interchange》2006,37(4):333-361

Despite official government srt (in various jurisdictions around the world) for providing students with opportunities to construct their own knowledge within the context of formal schooling, school science systems continue to place greatest priority on teaching and learning of products of science (e.g., laws and theories), while compromising students’ opportunities to develop realistic conceptions about science and expertise for doing science. Based on qualitative data analyzed using constant comparative methods (based on constructivist grounded theory), we found this also to be the case – paradoxically – in a school belonging to the Canadian Coalition for Self-directed Learning (CCSDL). Schools in this coalition espouse, among various goals, enabling students to construct their own knowledge, in ways and directions suiting their individual needs, interests, perspectives, and abilities, in addition to gaining access to knowledge developed by society. The science department within the coalition school in this study experienced considerable difficulty realizing this goal, despite school-level administrative support for a concerted effort to reinvent itself along these lines. Factors that appeared to influence the science department’s efforts included those in each of Schwab’s (1969) educational "commonplaces;” that is, the curriculum, teachers, students, and the milieu surrounding teaching and learning. Further analysis suggests that results can be explained through reference to a Kuhnian (1962/1996) paradigm conflict – in which the school’s administrative and curricular committee and other members of the CCSDL were unsuccessful in convincing members of the science department (who, in turn, appeared to be supported by the provincial government, parents, and students) to make provisions for more student-directed, openended science inquiry. Assuming that student-led scientific inquiry continues to be an important curricular goal, efforts must continue to be made, therefore, to convince members of the mainstream paradigm that it is a worthy goal.  相似文献   

Preschool Children and iPads: Observations of Social Interactions During Digital Play     

Sandra M. Lawrence 《Early education and development》2018,29(2):207-228

Research Findings: Digital play is now commonplace in many young children’s lives, but not in preschool settings. This situation is likely due to the fact that the existent literature seldom highlights what digital play looks like, the various ways it can be situated, and what young children do when they play together with digital devices in the preschool setting. The present study addresses this limitation by providing a close examination of the social interactions of young children as they engage with different types of iPad apps and each other. Observational data of 20 dyads of children during digital play analyzed qualitatively revealed that children exhibited a range of social behaviors from competitive to collaborative as they engaged in 4 types of digital play: practice/task, exploratory, construction, and pretense. Forms of play and exhibited behaviors were shaped by interrelated factors of children’s individual characteristics and relationships, classroom culture and routines, adult views and actions, as well as aspects of the digital device itself. Practice or Policy: Selecting open-design apps, attending to digital play structures, and monitoring peer play more closely may lessen competition, enhance collaboration, and lead to more complex digital play.  相似文献   

New evidence of relative age effects in “super-elite” sportsmen: a case for the survival and evolution of the fittest     

Benjamin D. Jones  Gavin P. Lawrence  Lew Hardy 《Journal of sports sciences》2018,36(6):697-703

The relative age effect (RAE) describes an overrepresentation of players born early (Q1) in a selection year and is highly prevalent within youth sport pathways. However, a dearth of research has investigated the RAE at the “super-elite” level. The present research assessed the presence of RAE in super-elite performers. Study 1 investigated RAEs in the world’s best international Test cricketers (N = 262) over a 20-year period according to a robust and stringent “super-elite” criteria. Results revealed the RAE (Q1) when all disciplines were combined. Upon closer examination, this effect was also observed for the batting and spin bowling disciplines, whereas no RAE was found for the pace bowling discipline. Study 2 investigated RAEs in super-elite rugby union players (N = 691) over a 20 year period. Results revealed the RAE for backs (Q1) and a reversal of the traditional RAE (Q4) for forwards, and when all rugby union positions were combined. These findings provide new evidence of RAEs at the super-elite level and present both inter and intra sports differences. Potential explanations for these findings are explored, owing to the survival and evolution of the fittest concepts, and the implications for future research and applied practice are presented.  相似文献
