Semiotic mediation in guiding interactions with young children: The role of context and communication handicap on distanciation in adult discourse     

Michel Deleau  Eva Gandon  Véronique Taburet 《European Journal of Psychology of Education - EJPE》1993,8(4):473-486

This paper pays attention to two factors often neglected in the studies of instructional or guidance interaction: the specifity of the child as interlocutor and the constraints exerted by the properties of the tasks on the semiotic means used to guide the child. Following Sigel’s ‘distanciation hypothesis’ we have studied the ‘distancing’ characteristics of the adult’s discourse adressed to the child in two groups of dyads, one with deaf (N=5), the other with hearing children (N=7) aged around 24 months, in two tasks: Symbolic Play and Picture — Book reading. The main results indicate a strong effect of the tasks, SP allowing more distanciation than PB for both categories. D-dyads show few differences in SP task but less ability to share references in Picture-Book reading. It appears also that with such young children, the distancing potential might be conveyed by the forms and pragmatic functions and not only by the semantic components of adult’s utterances.  相似文献   

Reciprocal (and Reductionist?) Newswork     

Robert E. Gutsche Jr.  Susan Jacobson  Juliet Pinto  Charnele Michel 《Journalism Practice》2017,11(1):62-79

This paper builds upon previous research that examines participatory forms of “reciprocal journalism” and “public communication” led by high school and college students in Miami, Florida, USA, in the fall of 2014. In this study, the students’ assessment of local and national media coverage is used to reveal greater details inherent in examining participatory methods of newswork. Collectively, students said that media coverage emphasis on local and national public officials instead of residents and community members who experience sea-level rise first-hand, combined with a lack of scientific explanation of and solutions for sea-level rise reduced the event's potential to build reciprocal relationships with younger audiences.  相似文献   

Upper limb joint muscle/tendon injury and anthropometric adaptations in French competitive tennis players     

Isabelle Rogowski  Thomas Creveaux  Cyril Genevois  Shahnaz Klouche  Michel Rahme  Philippe Hardy 《European Journal of Sport Science》2016,16(4):483-489

The purpose of this study was to examine the relationship between the upper limb anthropometric dimensions and a history of dominant upper limb injury in tennis players. Dominant and non-dominant wrist, forearm, elbow and arm circumferences, along with a history of dominant upper limb injuries, were assessed in 147 male and female players, assigned to four groups based on location of injury: wrist (n = 9), elbow (n = 25), shoulder (n = 14) and healthy players (n = 99). From anthropometric dimensions, bilateral differences in circumferences and in proportions were calculated. The wrist group presented a significant bilateral difference in arm circumference, and asymmetrical bilateral proportions between wrist and forearm, as well as between elbow and arm, compared to the healthy group (6.6 ± 3.1% vs. 4.9 ± 4.0%, P < 0.01; ?3.6 ± 3.0% vs. ?0.9 ± 2.9%, P < 0.05; and ?2.2 ± 2.2% vs. 0.1 ± 3.4%, P < 0.05, respectively). The elbow group displayed asymmetrical bilateral proportions between forearm and arm compared to the healthy group (?0.4 ± 4.3% vs. 1.5 ± 4.0%, P < 0.01). The shoulder group showed significant bilateral difference in elbow circumference, and asymmetrical bilateral proportions between forearm and elbow when compared to the healthy group (5.8 ± 4.7% vs. 3.1 ± 4.8%, P < 0.05 and ?1.7 ± 4.5% vs. 1.4 ± 4.3%, P < 0.01, respectively). These findings suggest that players with a history of injury at the upper limb joint present altered dominant upper limb proportions in comparison with the non-dominant side, and such asymmetrical proportions would appear to be specific to the location of injury. Further studies are needed to confirm the link between location of tennis injury and asymmetry in upper limb proportions using high-tech measurements in symptomatic tennis players.  相似文献

The genetic-environmental etiology of cognitive school readiness and later academic achievement in early childhood   总被引：1，自引：0，他引：1  

Lemelin JP  Boivin M  Forget-Dubois N  Dionne G  Séguin JR  Brendgen M  Vitaro F  Tremblay RE  Pérusse D 《Child development》2007,78(6):1855-1869

Using a genetic design of 840 60-month-old twins, this study investigated the genetic and environmental contributions to (a) individual differences in four components of cognitive school readiness, (b) the general ability underlying these four components, and (c) the predictive association between school readiness and school achievement. Results revealed that the contribution of the shared environment for cognitive school readiness was substantial. Genetic effects were more important for the core abilities underlying school readiness than for each specific skill, although shared environment remained the largest factor overall. Genetic, shared, and nonshared environmental factors all accounted for the predictive association between school readiness and early school achievement. These results contribute to a better understanding of the early determinants of school readiness.  相似文献   

Parent-Child Communication about Internet Use and Acceptance of Parental Authority     

Katrien Symons  Koen Ponnet  Ini Vanwesenbeeck  Michel Walrave  Joris Van Ouytsel 《广播与电子媒介杂志》2020,64(1):1-19

Structural equation modeling is applied to investigate how parents’ communication with their child about his or her Internet use is linked to the child’s acceptance of parental authority in the context of Internet use, and how this in turn is linked to the child’s social media behavior. This study surveyed children aged 13 to 18 and their mothers and fathers (N = 357 families) and found that acceptance of parental authority is a key factor in the effectiveness of parental mediation. It is recommended that parental mediation is studied as a dynamic process shaped by both parents and children.  相似文献   

Localized removal of layers of metal,polymer, or biomaterial by ultrasound cavitation bubbles     

David Fernandez Rivas  Bram Verhaagen  James R. T. Seddon  Aaldert G. Zijlstra  Lei-Meng Jiang  Luc W. M. van der Sluis  Michel Versluis  Detlef Lohse  Han J. G. E. Gardeniers 《Biomicrofluidics》2012,6(3)

We present an ultrasonic device with the ability to locally remove deposited layers from a glass slide in a controlled and rapid manner. The cleaning takes place as the result of cavitating bubbles near the deposited layers and not due to acoustic streaming. The bubbles are ejected from air-filled cavities micromachined in a silicon surface, which, when vibrated ultrasonically at a frequency of 200 kHz, generate a stream of bubbles that travel to the layer deposited on an opposing glass slide. Depending on the pressure amplitude, the bubble clouds ejected from the micropits attain different shapes as a result of complex bubble interaction forces, leading to distinct shapes of the cleaned areas. We have determined the removal rates for several inorganic and organic materials and obtained an improved efficiency in cleaning when compared to conventional cleaning equipment. We also provide values of the force the bubbles are able to exert on an atomic force microscope tip.  相似文献   

Development of implanted deaf children’s conversational skills     

Gaïd Le Maner-Idrissi  Virginie Dardier  Cécile Pajon  Géraldine Tan-Bescond  Kristell David  Michel Deleau  Benoit Godey 《European Journal of Psychology of Education - EJPE》2010,25(3):265-279

Previous studies of preverbal development have highlighted the recurrent difficulties experienced by deaf children in acquiring knowledge of the social rules and social skills pertaining to discourse. We expected cochlear implants in children with bilateral profound deafness to improve their use of verbal language, so that their communication skill profile resembled that of younger, hearing children. Using conversation samples taken from videos recorded every 6 months over a 2-year period, we monitored the development of communication skills in a group of 18 prelingually profoundly deaf children (mean implantation age, 3 years and 5 months). Results corroborated our hypothesis that the overall communication performances of children with cochlear implants improve, both quantitatively and qualitatively, as early as the first year post-implantation.  相似文献   

Case studies from morning report: librarians' role in helping residents find evidence-based clinical information     

Atlas MC  Smigielski EM  Wulff JL  Coleman MT 《Medical reference services quarterly》2003,22(3):1-14

In primary care specialties, Morning Report is a traditional vehicle for expanding medical residents' training in diagnosis and treatment. At one academic medical center, residents and faculty in the Department of Family and Community Medicine use case-based teaching, centered around planning and reviewing patient management, to review intriguing cases from patient encounters in the department's hospital service. Seeking to improve the level of evidence-based information exchanged at Morning Report, department leaders invited reference librarians from the health sciences library to attend weekly Morning Report. The librarians saw this as an opportunity not only to improve residents' information-seeking skills, but also to improve librarians' teaching skills and understanding of the needs of users in clinical settings. This paper describes the evolution of librarians' involvement in Morning Report, examples of the kinds of contributions librarians have made in this setting, and changes made in Morning Report sessions to facilitate this activity.  相似文献
