Research Findings: The purpose of this study was to describe differences in the narratives produced by 3-, 4-, and 5- year old Spanish-speaking (SS) children. Narrative productions of 104 typically developing children were collected using a story-retelling task and coded using the Index of Narrative Complexity. The results of this study indicate that 3-year-old SS children produced stories containing characters and actions. Four-year-old SS children’s stories were characterized by the use of characters, actions, and internal responses. Five-year-old SS children retold stories containing characters, settings, initiating events, actions, internal responses, formulaic markers, temporal markers, and knowledge of dialogue. Practice: Developmental information to assist educators working with SS children.  相似文献

Abstract

We compared the movement patterns of cricketers in different playing positions across three formats of cricket (Twenty20, One Day, multi-day matches). Cricket Australia Centre of Excellence cricketers (n = 42) from five positions (batting, fast bowling, spin bowling, wicketkeeping, and fielding) had their movement patterns (walk, jog, run, stride, and sprint) quantified by global positioning system (GPS) technology over two seasons. Marked differences in movement patterns were evident between positions and game formats, with fast bowlers undertaking the greatest workload of any position in cricket. Fast bowlers sprinted twice as often, covered over three times the distance sprinting, with much smaller work-to-recovery ratios than other positions. Fast bowlers during multi-day matches covered 22.6 ± 4.0 km (mean ± s) total distance in a day (1.4 ± 0.9 km in sprinting). In comparison, wicketkeepers rarely sprinted, despite still covering a daily total distance of 16.6 ± 2.1 km. Overall, One Day and Twenty20 cricket required ～50 to 100% more sprinting per hour than multi-day matches. However, multi-day cricket's longer duration resulted in 16–130% more sprinting per day. In summary, the shorter formats (Twenty20 and One Day) are more intensive per unit of time, but multi-day cricket has a greater overall physical load.  相似文献

The memory of science: Inflation,myopia, and the knowledge network     

Raj K. Pan  Alexander M. Petersen  Fabio Pammolli  Santo Fortunato 《Journal of Informetrics》2018,12(3):656-678

Scientific production is steadily growing, exhibiting 4% annual growth in publications and 1.8% annual growth in the number of references per publication, together producing a 12-year doubling period in the total supply of references, i.e. links in the science citation network. This growth has far-reaching implications for how academic knowledge is connected, accessed and evaluated. Against this background, we analyzed a citation network comprised of 837 million references produced by 32.6 million publications over the period 1965–2012, allowing for a detailed analysis of the ‘attention economy’ in science. Our results show how growth relates to ‘citation inflation’, increased connectivity in the citation network resulting from decreased levels of uncitedness, and a narrowing range of attention – as both very classic and very recent literature are being cited increasingly less. The decreasing attention to recent literature published within the last 6 years suggests that science has become stifled by a publication deluge destabilizing the balance between production and consumption. To better understand these patterns together, we developed a generative model of the citation network, featuring exponential growth, the redirection of scientific attention via publications’ reference lists, and the crowding out of old literature by the new. We validate our model against several empirical benchmarks, and then use perturbation analysis to measure the impact of shifts in citing behavior on the synthetic system's properties, thereby providing insights into the functionality of the science citation network as an infrastructure supporting the memory of science.  相似文献   

In the Light of Media     

Solveig Jülich 《Media History》2016,22(2):201-216

This paper aims to highlight the medical and medial relationships that were established and negotiated through the mass X-ray surveys for tuberculosis in Sweden from the early 1940s to 1970. In particular it focuses on three interrelated aspects. Firstly, it shows how mass miniature radiography was developed through the pairing of old X-ray technology with new photographic technology. Secondly, it demonstrates how the survey campaigns enabled connections between medical and media institutions and professional groups. Thirdly, it discusses how the mass surveys helped to create and mediate relations between doctors and patients, experts and lay people, sick and healthy people, participants and objectors. In conclusion, it argues that these three aspects together are crucial if we wish to understand the mediatisation of the medical sphere as well as the medicalisation of everyday life during the twentieth century.  相似文献   

Facilitators and Barriers to the Implementation of EMOTION: An Indicated Intervention for Young Schoolchildren

ABSTRACT

Research on implementation of school-based transdiagnostic interventions, conducted by personnel from the municipal services is limited. We investigated facilitators and barriers regarding implementation of EMOTION, an intervention targeting symptoms of anxiety and depression in children 8–12 years. Trained health- and childcare professionals completed one questionnaire before (N?=?63) and a separate questionnaire after running an EMOTION group (N?=?66). Twelve of the group leaders were interviewed to provide additional information regarding implementation. Results indicated that factors such as a perceived need for the intervention and positive attitudes from the group leaders facilitated implementation. Hindering factors were related to time constraints, workload, unsupportive leaders, and lack of cooperation from the schools. Allocating resources to implementation specifically could promote future use of the program.  相似文献   

A Preliminary Assessment of the Impact of Counseling on Student Adjustment to College     

Thomas J. DeStefano  Ramona N. Mellott  Jerry D. Petersen 《Journal of College Counseling》2001,4(2):113-121

This study compared adaptation to college for students receiving counseling at a university counseling center with adaptation by control counterparts. Students receiving counseling initially reported lower adaptation scores as measured by the Student Adaptation to College Questionnaire. After counseling, scores no longer differentiated between the 2 groups. Results suggest that counseled students were affected positively by this experience.  相似文献   

Emergence and characterization of sex differences in spatial ability: a meta-analysis   总被引：21，自引：0，他引：21  

M C Linn  A C Petersen 《Child development》1985,56(6):1479-1498

Sex differences in spatial ability are widely acknowledged, yet considerable dispute surrounds the magnitude, nature, and age of first occurrence of these differences. This article focuses on 3 questions about sex differences in spatial ability: What is the magnitude of sex differences in spatial ability? On which aspects of spatial ability are sex differences found? and When, in the life span, are sex differences in spatial ability first detected? Implications for clarifying the linkage between sex differences in spatial ability and other differences between males and females are discussed. We use meta-analysis, a method for synthesizing empirical studies, to investigate these questions. Results of the meta-analysis suggest that sex differences arise on some types of spatial ability but not others, that large sex differences are found only on measures of mental rotation, that smaller sex differences are found on measures of spatial perception, and that, when sex differences are found, they can be detected across the life span.  相似文献

Here is a book that makes you want to shout, ‘Finally!’For decades, political scientists and communication researchershave been focusing intensively on the question of how peoplemake their final voting decision and how this decision is influencedby reporting in the mass media and campaign advertising. Nevertheless,even though there is enough literature on this subject to filla library, only very few studies have dealt with the issue ofemotional appeals in election coverage and campaign advertising—andvoters’ emotional, possibly irrational reactions to theseappeals. Although numerous findings in the fields of psychology,neuroscience, and behavioral research suggest that emotionalappeals and reactions play an important role when it comes toall kinds of decisions—which, of course, also includesvoting decisions—social researchers in the United Statesand elsewhere have,  相似文献   

An ethnographic field study of the influence of social interactions during the school day for children diagnosed with ADHD

The aim of this ethnographic field study was to investigate the influence of school-day social interactions on the well-being and social inclusion of children diagnosed with ADHD. The empirical data consisted of participant observations and informal interviews over a three-month period at a Danish primary school. Two ADHD-diagnosed 11-year-old boys in the fourth and fifth grades were followed on an alternating basis. The field notes were analysed using a qualitative content analysis that incorporated Etienne Wenger’s concepts of social identity and participation. The results revealed that the effects of school-day social interactions are complex and situation dependent. Medication, friendships and relationships with teachers and other adults strongly influence how children diagnosed with ADHD participate in social interactions and, consequently, how they thrive. We argue that it is important to emphasise the mediation of these children’s participation in the classroom community throughout an entire school day to ensure their social inclusion and well-being.  相似文献
