K2 Children's Learning of National Identity in Singapore

In May 1991, a quasi-experimental research study was launched to investigate Singapore K2 children's learning of national identity and the effect of parental involvement in the learning process. A specially designed and pilot-tested 43-item questionnaire was used to interview a sample of 329 K2 children randomly selected from the participating education centres and kindergartens. A 4-week intervention (five 20-min lessons plus one home-based exercise each week) was implemented after the pre-test had taken place in early July 91. The same sample of children was interviewed again in mid August, after the celebration of National Day on 9 Aug 91. The post-test scores showed there was an increase of the awareness as well as fondness of Singapore as their nation among the children in the study. The research design and findings of data analyses are presented and discussed in this paper.     

Pre-service teachers’ attitude towards inclusive education for students with Autism Spectrum Disorder in Malaysia

In this study, the pre-service teachers’ attitudes towards the educational inclusion for students with Autism Spectrum Disorder (ASD) were investigated to identify their attitudinal patterns and predictors. An attitudinal survey was conducted with 264 pre-service teachers in a teacher training programme in Malaysia. The study involved 151 special education pre-service teachers and 181 pre-service teachers in Special Education, Sciences, and in English teacher training programmes, in order to identify the effects of teaching specialisations and societal attitude on their inclusive education attitudinal measures. The findings revealed that the special education pre-service teachers were less in favour of the total inclusion of students with ASD in the mainstream, when compared with the non-special education pre-service teachers. The findings also revealed the combined effects of societal attitude and a categorical teacher training model in shaping the pre-service teachers’ attitudes towards inclusive education for the students with ASD in Malaysia. Such combined effects offered a perspective to explain the delay in the implementation of inclusive education, and also the prospect of its future development in the Southeast Asian region.     

An analysis of conference interactions onTeleNex—A computer network for ESL teachers

“TeleNex” is a computer network set up to enhance the professional development of inservice English teachers in Hong Kong by allowing them to access and share curriculum materials and to communicate with teacher educators at The University of Hong Kong and fellow teachers in other schools. This paper reports a study on the characteristics of the interactions in the public conferences on “TeleNex” during its first 16 months of full operation and the possible factors contributing to these characteristics. In order to analyze the various aspects of conference interactions, including teacher participation, initiation and response, response patterns and message types, a framework of message analysis was developed, drawing on concepts in conversational and discourse analysis. To investigate the possible contributing factors, a questionnaire was designed and administered to all users at the end of the 16-month period. The interaction analysis results and the questionnaire results confirmed the findings in previous studies carried out by the authors that social and psychological factors were very important in shaping the network interactions. TeleNex (Teachers of English Language Education Nexus) is a computer network set up by TELEC with a generous donation from the Hong Kong Telecom Foundation. The Hong Kong Language Fund provided further funding for its third year of operation (1995-96). The research side ofTeleNex is funded by the Research Grants Council of The University Grants Committee of Hong Kong. The authors wish to thank the Hong Kong Telecommunications Foundation and the Hong Kong Language Fund for their generous support. They also wish to thank all colleagues at TELEC who have worked tirelessly to set up the network. In particular, they wish to thank Suzi Nicholson for her comments on the draft. Finally, they wish to thank the editor Steven Ross for his detailed comments and suggestions for revision.     

Analysis of a load application point in spline coupling teeth

The objective of this paper is to investigate the position of the resultant force in involute spline coupling teeth due to the contact pressure distribution for both ideal and misaligned conditions. In general, spline coupling teeth are in contact all along the involute profile and the load is far from uniform along the contact line. Theoretical models available in publications consider the resultant contact force as it is applied at the pitch diameter, and this study aims to evaluate the error introduced within the confines of a common approximation environment. This analysis is carried out through using finite element method （FEM） models, considering spline couplings in both ideal and misaligned conditions. Results show that the differences between the load application diameter and pitch diameter are not very obvious in both ideal and misaligned conditions; however, this ap- proximation becomes more important for the calculation of the tooth stiffness.     

Agenda Setting and Priming Effects Based on Information Presentation: Revisiting Accessibility as a Mechanism Explaining Agenda Setting and Priming

In three experiments, this investigation evaluated the sufficiency of construct accessibility in explaining individual-level agenda setting and priming outcomes. Participants were exposed to an issue presented within a story from a respected news source (e.g., New York Times), a story from an unknown individual's blog, a story from a respected non-news organization (e.g., National Geographic), a crossword puzzle from a respected news source, or a crossword puzzle from an online game website. Story and crossword content was constant across the different sources. Participants responded either to a measure of implicit priming or to the traditional agenda setting question asking what the most important issue in the nation is. Priming effects were robust across presentation context, indicating a successful increase in temporary accessibility. Agenda setting effects were strongest when information came from news than from non-news sources, regardless of whether the issue was presented within a story or crossword. Findings suggest that issue salience in agenda setting is more appropriately conceptualized as perceived importance rather than top-of-mind awareness. News sources uniquely cue this salience beyond the abilities of other respected organizations.     

“Real life use” of troponin in the emergency department: a survey of over 3000 cases

Introduction

The aim of this study was to identify clinical variables which may be independently associated with positivity of a cardiac troponin I (cTnI) assay in a large population of patients admitted to the emergency department (ED).

Materials and methods

3166 subjects, with at least two troponin I tests ordered within 6 hours in the ED, were studied. Patient data were statistically analyzed to identify clinical associations with increased values of Troponin I.

Results

Although patients with diagnosis of acute coronary syndrome displayed troponin I values significantly higher than those of other groups, positivity to troponin I (> 40 ng/L) was also observed in patients with other clinical conditions. In multivariate analysis, age, elevated heart rate and electrocardiographyc changes were independently associated with troponin I positivity at admission. In the whole study population troponin I positivity exhibited high sensitivity and negative predictive value, counterbalanced by low specificity and limited positive predictive value.

Conclusions

Troponin I positivity should be combined with history and clinical evaluation and cautiously interpreted in the ED, especially in patients exhibiting factors associated with higher troponin I levels such as older age, elevated heart rate or ECG changes.Key words: troponin I, acute coronary syndrome, emergency service, hospital, chest pain     

Creating and Sustaining Inclusive Instructional Settings for English Language Learners: Why,What, and How

In this article, we provide an empirically based framework for school leaders to support the replacement of separate means of providing services for English learners (ELs) with more inclusive learning supports. The framework encompasses evidence on cultivating language proficiency, ensuring access to a high-quality curriculum, and promoting sociocultural integration. To illustrate the ways that research has informed practice to better meet the needs of ELs, we also present initiatives by the Wisconsin Department of Public Instruction that have helped propel a vision of equity and diversity at both the school and district level. We conclude by providing additional resources that leaders can use to promote the professional growth of the school.     

Perceptual completion in newborn human infants

Despite decades of studies of human infants, a still open question concerns the role of visual experience in the development of the ability to perceive complete shapes over partial occlusion. Previous studies show that newborns fail to manifest this ability, either because they lack the visual experience required for perceptual completion or because they fail to detect the pattern of motion. To distinguish these possibilities, newborns' perception of a center-occluded object was tested, using stroboscopic motion. Infants (mean age of 72 hr) perceived the object as a connected unit, providing the first evidence that the newborn is capable of filling in gaps in the visible surface layout when the relevant visual information can be detected by his or her immature visual system.     

Efficacy of a cultural adaptation of the Identity Project intervention among adolescents attending multiethnic classrooms in Italy: A randomized controlled trial

This registered report evaluated the efficacy of an Italian adaptation of the Identity Project, a school-based intervention promoting adolescents' cultural identity. Migration background and environmental sensitivity were explored as moderators. After adapting and piloting the intervention, a randomized controlled trial was conducted between October 2021 and January 2022 on 747 ethnically diverse adolescents (M_age = 15 years, 53% girls, 31% with migration background) attending 45 classrooms randomly assigned to the intervention or control condition. Bayesian analyses confirmed the efficacy of the Italian IP in enhancing exploration processes (Cohen's d = .18), whereas no cascading effect on resolution emerged. Youth with higher (vs. lower) levels of environmental sensitivity benefited more in terms of exploration. Implications for developmental theory and practice are discussed.
