Cross-linguistic analysis of vocabulary in young children: spanish, dutch, French, hebrew, italian, korean, and american english

The composition of young children's vocabularies in 7 contrasting linguistic communities was investigated. Mothers of 269 twenty-month-olds in Argentina, Belgium, France, Israel, Italy, the Republic of Korea, and the United States completed comparable vocabulary checklists for their children. In each language and vocabulary size grouping (except for children just learning to talk), children's vocabularies contained relatively greater proportions of nouns than other word classes. Each word class was consistently positively correlated with every other class in each language and for children with smaller and larger vocabularies. Noun prevalence in the vocabularies of young children and the merits of several theories that may account for this pattern are discussed.     

Technological requirements of profile machining

INTRODUCTION Many products, from automotive body panels to television consoles, are designed with sculptured surfaces, and all rely on sculptured surface machining technology for the production of the dies and moulds used in manufacturing. Since the quality of machining is no better than the quality of its tool path, generating an accurate tool path in an efficient manner has been investigated by numerous researchers. Profile ma- chining refers to the milling vertical surfaces de- scribed …     

How the second screens change the way people interact and learn: the effects of second screen use on information processing

The use of a second screen can enhance information processing and the execution of search tasks within a given period. In this study, we examined the learner's attentional shift (AS) between two screens and controlled secondary tasks (STs) in the media multitasking setting and its effect on the learning process. In particular, we analyzed how cognitive and emotional learning effects can be explored depending on the role of this setting. A between-subject experiment was conducted with 69 participants (simultaneous vs. sequential use of a second screen in terms of open versus closed STs). The findings showed that there was a greater difference in emotional learning effects than in cognitive learning effects for participants who used a second screen. In terms of estimated emotional learning effects of media multitasking, participants engaged in sequential use demonstrated lower anxiety levels and higher competence beliefs during learning compared to participants who were engaged in simultaneous use. Moreover, an interaction effect occurred in the AS between the two screens and in controlled STs of recognition memory. These results indicate that attentional change and controlled STs are key predictors of learning effects in the media multitasking environment.     

Self-Concept/Ideal-Self-Concept Congruence and Rated Effectiveness of Counselor Trainees

Sixty-nine counselor trainees in Alberta, Canada, completed the Interpersonal Check List at the beginning and end of their training year. On both occasions trainees responded to a “set” for self-concept and self-ideal. The congruence between self and ideal (S-I) was tested for both linear and curvilinear relationships with supervisor ratings and final practicum grades of students. A curvilinear relationship was found between (S-I) congruence and final performance measures for full-time male practicum students, suggesting the presence of an optimal range of S-I congruence.     

Professional Characteristics and Teacher Professionalism of Secondary School Teachers

Questionnaire responses from 338 secondary school teachers were analysed to relate teachers' professional characteristics (comprising teaching experience, professional development, and academic and professional qualifications) to teacher professionalism, defined in terms of the two dimensions, teaching competence and commitment to teaching. The Professional Development and Teacher Professionalism Instrument (PDTPI) was devised to measure professional development and teacher professionalism. Inferential statistical techniques employed in the study showed that the variable, teaching experience, was not related to teacher professionalism. Professional development, on the other hand, was found to be an important variable, with the mean teacher professionalism scores between the “high” and “low” professional development groups being significantly different. The study also found that academic qualification was not related to teacher professionalism. However, teachers who had higher professional qualifications were found to possess a higher degree of teacher professionalism.     

Aggressor/victim subtypes and teacher factors in first grade as risk factors for later mental health symptoms and school functioning

In a sample of 244 first graders, we identified four subtypes of children based on multi-informant measures of victimization by peers and aggression toward peers: aggressive victims (AV), non-victimized aggressors, non-aggressive victims, and non-aggressive, non-victimized (i.e., normative) children. We examined the differences between the aggressor/victim groups concurrently and two years later in third grade in terms of both mental health symptoms (severity and directionality) and school functioning (academic competence and school engagement). AV showed the worst results for mental health, academic competence, and school engagement concurrently and two years later. The role of first-grade teacher experience and education in predicting third-grade outcomes was also the subject of examination. Significant interactional effects were found between both AV and teacher experience and education. Most notably, the education level of first-grade teachers interacted with AV status to predict school engagement, such that the least engaged students at third grade were AV whose first-grade teachers had no schooling beyond a bachelor’s degree.     

A Web-based machining process monitoring system for E-manufacturing implementation

INTRODUCTION Recently, the application of the information technology into manufacturing fields gets more and more importance on the whole manufacturing shop floors. Currently, many researches reflect the effec- tiveness of knowledge-based production system re- lated to the exchange and management of various manufacturing information using information tech- nology via the Internet in order to increase the com- petitive power of industries. This research suggests a Web-based machining proce…     

Effect of encoding instructions on children's spatial and color memory: is there evidence for automaticity?

This experiment is concerned with assessing whether there is evidence for the automatic processing of spatial and color information by children and with the development of control of encoding operations. First, third, and fifth graders viewed pictures of simple objects that varied in color (red or green) and spatial location (left or right). Subjects were instructed to encode (a) only the item, (b) the item and its color, (c) the item and its position, (d) the item, its color, and its position. The data yielded evidence for nonchance incidental memory of spatial, but not color, information. The data also suggested that children at all age levels were able to control their encoding operations similarly, as there was no evidence for an interaction of development with encoding instructions. These findings are discussed with respect to a model for automatic encoding processes and work on memory for central and incidental information.     

A review of human competence in educational research: Levels of K- 12, College, Adult, and Business Education

The purpose of this study is to review the main perspectives or issues dealt with in the research on considered to be key competences, in order to develop a fuller understanding of how human competence functions. As a result of this review, two themes considered as having important implications for the actual practices can be identified: that there exists an holistic nature with different aspects of a given competence and that influences of a contextual and cultural nature are factors which affect the operation of human competence. By incorporating four characteristics and three domains of competence with the review conducted in this study, we began to appreciate what the research on human characteristics related to key competences has achieved and what is needed for future research.
