This study investigated the role of working memory capacity as a factor for individual differences in the ability to compose a text with communicative efficiency based on audience awareness. We analyzed its differential effects on the dynamics of the writing processes, as well as on the content of the finished product. Twenty-five graduate students composed a procedural text explaining how to assemble a model turbine. They were free to consult a documentary source, featuring captioned pictures of turbine parts and assembly steps, at any time. Graphomotor and eye movements were recorded using ‘Eye and Pen’ software with an eye-tracker and digitizing tablet. Results showed that high WM capacity writers used a different strategy to explore the visual source, making longer writing pauses and producing more detailed procedures, and achieved the communicative goal more efficiently, by introducing more reader supports. In conclusion, we discuss the feasibility of audience awareness training. 相似文献

The rapid development of ICT （information technology and communication） in the last two decades has changed society substantially as a whole. For higher education institutions, the external environment pressure to incorporate ICT in their educational and administrative processes has forced them to invest in resources for infrastructure and training. In addition, teachers have found that they can use technology in their teaching, but lack of full knowledge of how to use it effectively from a pedagogical point of view. The incorporation of new education modalities depends largely on the contextual variables prevailing in the institution and teachers. In UABC （Autonomous University of Baja California）, the early days of online education go hack to 1996, so the study period was from 1996 to 2009. An online survey was designed to fmd out the teachers＇ backgrounds and involvement in online education, their experience as online teachers, and the tools and practices used. Of 97 teachers who were identified with some experience in online teaching, 70% responded to the Survey （68）. It was found that the highest percentage （33%） of teachers who responded the survey started teaching online between 2003 and 2006. 56% of teachers have been teaching between one and five online courses. On the other hand, most teachers recognized that 30%-79% of the content of their courses were online based. The most popular learning management system used is moodle followed by blackboard in teachers＇ preference. In general, teachers expressed using the three main communication tools of online education： forums, chat and e-mail, favoring the use of e-mail. The communication slrategies teachers often use in their courses promoted student-student and student-teacher interaction. In their evaluation strategies, most said that they used self-assessment, rubrics and to a lesser extent online exams and co-evaluation. The results show that most teachers who have been involved in online education in UABC campus have expressed havi 相似文献

Objective
We sought to determine the incidence, clinical features, and demographic profile of head injury secondary to suspected child maltreatment (abuse or neglect) in Canada to help inform the development and evaluation of prevention programs for abusive head injuries.Methods
From March 1, 2005 to February 28, 2008, an average of 2,545 paediatricians and paediatric subspecialists were surveyed monthly through the established network of the Canadian Paediatric Surveillance Program. We calculated incidence rates using the number of confirmed cases over the product of the duration of the study (3 years) and population estimates by age group.Results
There were 220 confirmed cases of head injury from suspected child maltreatment. The annual incidence rate was 14.1 per 100,000 for children less than 1 year of age and 1.4 per 100,000 for those less than 15 years. Seventy three percent (141) of cases involved infants less than 12 months of age and 52% (100) of cases involved infants less than 6 months of age. Seventy-five percent (165) of cases presented to the emergency room. With regard to outcome, 12% (27) of cases resulted in death and 45% (75) of survivors had neurological sequelae at discharge. Thirty percent (67) of all cases, as well as 30% (8) of deaths were previously known to child welfare authorities.Conclusion
This study provides an estimate of the rate of head injury secondary to suspected child maltreatment in Canada. The young age and poor medical outcomes of those involved highlights the need for prevention efforts that are implemented early in life. Given that a significant percentage of injured infants and children were already known to child welfare authorities, the study also highlights the need to establish and evaluate additional preventive efforts for parents and caregivers already in the child welfare system. 相似文献4.

To evaluate Information Retrieval Systems on their effectiveness, evaluation programs such as TREC offer a rigorous methodology
as well as benchmark collections. Whatever the evaluation collection used, effectiveness is generally considered globally,
averaging the results over a set of information needs. As a result, the variability of system performance is hidden as the
similarities and differences from one system to another are averaged. Moreover, the topics on which a given system succeeds
or fails are left unknown. In this paper we propose an approach based on data analysis methods (correspondence analysis and
clustering) to discover correlations between systems and to find trends in topic/system correlations. We show that it is possible
to cluster topics and systems according to system performance on these topics, some system clusters being better on some topics.
Finally, we propose a new method to consider complementary systems as based on their performances which can be applied for
example in the case of repeated queries. We consider the system profile based on the similarity of the set of TREC topics
on which systems achieve similar levels of performance. We show that this method is effective when using the TREC ad hoc collection. 相似文献

The purpose of this study was to demonstrate the respective effects of cognitive abilities and personality traits on academic
achievement. The subjects were 141 sixth-grade French adolescents (mean age: 12) who took three cognitive tests (g factor,
numerical ability, and spatial ability) and answered a personality questionnaire based on the Big Five Model. Path analyses
indicated that Openness-intellect had an effect on junior high school achievement in all disciplines, with most effects being
indirect ones mediated by verbal achievement (French). Neuroticism-anxiety also had an effect, although not as marked and
mainly on mathematics. Personality is complementary to abilities in predicting academic achievement. Possible conceptual extensions
and field applications are addressed in the conclusion. 相似文献

The first important monograph describing the battered child syndrome was written in 1860 by Ambroise Tardieu, a French forensic physician. Here is a translation of his article, published in the Annales d'hygiene publique et de medecine legale, with the title "Etude medico-legale sur les sevices et mauvais traitements exerces sur des enfants." The first part of his article is entirely translated. A brief summary of the 32 cases report described by Tardieu in the second part of his article is presented. 相似文献

Recognition at the full professional level of engineers coming from two different countries with totally different systems is a very difficult task. However, in the context of globalization of all human activities, particularly engineering services, it is essential that well-developed countries take very serious efforts using an open-minded approach to establish the parameters that will permit the ultimate objective of international recognition to be achieved. While there are many ways to move toward this objective, one recognized method of making very important steps is certainly the signature of mutual recognition agreements by major players in the trade of engineering services. In this context, this paper presents the features of a bilateral agreement that has been signed between France and Canada for the recognition of engineers at the full professional level from both countries. This agreement is the first of its kind for Canada. Many features of the agreement are worthy of note for others trying to identify the parameters to achieve an agreement between two countries having very different systems. How this success was achieved is explained, giving full attention to those factors that contributed to the conclusion of this agreement. 相似文献

It is a common practice to use several chemical products during restoration projects of monuments or sculptures. However, care must be taken when combining the products to avoid a misuse. For example, it is well-known that applying a biocide on stone before a water-repellent leads to a diminishment of the hydrophobic effect of the treatment. But the application of biocide after a water-repellent treatment has been poorly analysed, although studies have proven that the stone looses its hydrophobicity after the application of the biocide. Henceforth, this study investigates the effects of biocide application on a water-repellent film and focuses on the possibilities to restore the efficiency of the previous water-repellent treatment (after the application of the biocide). At first, the tests were performed on glass slides to understand the mechanisms, with the subsequent results revealing that the biocide product deposits on the water-repellent film. Then, the study focuses on determining methods to remove the remains of biocide on limestone samples, previously treated with a water-repellent. The water-repellent used in the study is an alkylpolysiloxane, Rhodorsil H224 from Rhodia. 相似文献

The importance of encouraging language skills in early childhood has been well documented. Educators who are responsible for
children in daycare services have many opportunities to use rich and stimulating educational practices that support language
acquisition. The purpose of this study was to assess the language-support practices used by 22 educators in ECE centers with
174 children (87 girls and 87 boys) aged 55.7 months on average (SD = 4.2). The Teacher Interaction and Language Rating Scale
developed by Girolametto et al. (Teacher interaction and language rating scale, Hanen Centre, Toronto, 2000) was translated and adapted for use in French. Analyses reveal the heterogeneity of language support provided to 4-year-old
children attending early childhood education centers in Québec (Canada). Results are discussed in relation to the importance
of the educational setting and specific training on language skill development provided to educators around promoting language
skills in children, a fundamental prerequisite for educational success. 相似文献
