Graphene Based Electrochemical Sensor for the Detection of Volatile Organic Compounds

Many household consumables contain volatile organic compounds(VOCs)as the active ingredient.Long term exposure to VOCs could cause various health problems,especially to the respiratory system.Graphene has attracted a lot of attention recently for its potential to be used as sensing material for VOCs.In this project we have constructed graphene/PVA composite based gas sensors for VOC detection.It was perceived that the polymer could introduce better selectivity to the sensor.Results suggest that the proposed sensor is highly sensitive to low molecular weight VOCs and that the manner in which the sensor respond to the vapour depends on the polarity or hydrophobicity of the vapour.     

Collaborating with front-line teachers to incorporate self-regulated learning in Chinese language classes

This study aimed to initially explore the possibility of helping front-line teachers to integrate the principles of self-regulated learning (SRL) into Chinese reading instruction in a 1-year collaborative project. A total of 197 Secondary 3 students and 6 Chinese language teachers from a secondary school in Hong Kong participated in the study. The findings of quantitative and qualitative data in this study generally support the feasibility of incorporating the elements of SRL in Chinese reading instruction. Students improved their comprehension performance, intrinsic motivation, strategic knowledge, and strategy use after this learning experience. Teachers also expressed positive attitudes towards the new instruction and made constructive changes on the instructional materials and activities. However, the study found teachers' traditional beliefs might affect theimplementation of SRL instruction. The implications of these findings for understanding Chinese students' capacity for SRL and planning effective reading instruction to enhance their SRL abilities are discussed.     

The roles of teacher efficacy in instructional innovation: its predictive relations to constructivist and didactic instruction

Constructivist instruction has been implemented in the current instructional innovation in Singapore. Large scale survey study was conducted to examine the roles of teacher efficacy in implementing the innovative constructivist instruction. The results showed that the positive correlation between teacher efficacy and constructivist instruction was stronger than the correlation between teacher efficacy and didactic instruction. The study suggests that policy makers and school leaders should try to improve teacher’s efficacy beliefs so that innovative instruction could be effectively implemented by school teachers.

The effects of cognitive strategy instruction on Chinese reading comprehension among Hong Kong low achieving students

This study aimed to investigate the effectiveness of cognitive strategy instruction (CSI) on Chinese reading comprehension of Hong Kong low achieving students. A total of 88 Grade 7 students from four intact Chinese language remedial groups were randomly assigned to treatment and control conditions. Students in the treatment group received a 6-week Chinese CSI Program in their regular Chinese language lessons. The findings in this study generally supported that the Program had a positive impact on the reading development of low achieving students. Students who received strategy instruction made superior gains in comprehension performance, used more strategies during their reading process, had more knowledge about, strategy use, and showed a more positive attitude toward the reading instruction than did their peers who received traditional Chinese language instruction. Students’ improvements on their strategy use and reading comprehension were maintained 4 months after the termination of the Program. However, the positive treatment effects of the Program were not transferred to other school subject materials, and students’ reading motivation did not have significant changes after the Program. Factors contributing to the success of the Program as well as its limitations are discussed.     

Parenting and childhood aggression in the Chinese context: an examination of parental responses,physical coercion and warmth

Parental response, physical coercion and warmth and their relationships with childhood aggression were assessed with 277 children (142 boys; M age = 56.5 months, SD = 10.93 months) in Hong Kong. Results indicated that both fathers and mothers reported significantly more intervention strategies in response to hypothetical vignettes of physical aggression than relational aggression. Both fathers’ and mothers’ self-reported physical coercion was positively correlated with boys’ and girls’ composite scores of physical and relational aggression as reported by teachers, fathers and mothers, whereas fathers’ self-reported warmth was associated with a lower level of physical and relational aggression in boys. Furthermore, maternal warmth moderated the association between physical coercion and girls’ relational aggression. Findings suggest that parents’ normative beliefs regarding relational aggression should be challenged and the general acceptability of parental control in the Chinese context does not necessarily imply the absence of a link with childhood aggression.     

Dynamics of Chinese nationalistic education in Hong Kong from 1945 to 2012

‘Chinese’ is an ambiguous term, depending on whether it is taken to describe a political, linguistic, or cultural entity. While the term has often been considered to represent a politically and culturally homogeneous national identity in recent decades, this article aims to challenge this notion by examining the characteristics and practices of nationalistic education in Hong Kong since 1945. It explores how national identity has been interpreted by different Chinese states over time through different educational policies and practices. Focusing on the evolution of nationalistic education in three phases, this article presents a detailed account and analyses different nationalist narratives over six decades. It describes how different political forces define themselves and come to terms with what are often dual or competing national identities. Historical examples illustrate the challenges in policies and practices of nationalistic education.     

Coparenting,Parenting Stress,and Authoritative Parenting among Hong Kong Chinese Mothers and Fathers

SYNOPSIS

Objective. This paper examines whether the effects of spousal coparenting on authoritative parenting are mediated through parenting stress. Design. A total of 166 married, heterosexual couples in Hong Kong with a preschool child provided information about their spouse’s level of cooperation and triangulation in their coparenting relationship at Time 1; their own parenting stress at Times 1 & 2; and their authoritative parenting at Times 1, 2, and 3. Results. Cooperation at Time 1 affected fathers’ authoritative parenting at Time 3 completely mediated through fathers’ parenting stress at Time 2. There were no mediated or direct effects on authoritative parenting for mothers, although triangulation at Time 1 predicted mothers’ parenting stress at Time 2. Conclusion. Parenting stress mediates the relation between coparenting and authoritative parenting for fathers, suggesting the need to encourage cooperation from mothers. In this way fathers’ stress related to their role as parent will decrease, helping to promote their authoritative parenting.

What's in a name? A comparison of methods for classifying predominant type of maltreatment

OBJECTIVE: The primary aim of the study was to identify a classification scheme, for determining the predominant type of maltreatment in a child's history that best predicts differences in developmental outcomes. METHOD: Three different predominant type classification schemes were examined in a sample of 519 children with a history of alleged maltreatment. Cases were classified into predominant maltreatment types according to three different schemes: Hierarchical regression analyses examined whether the HT, SFT, and EHT type classifications contributed to prediction of child behavior problems, trauma symptoms and adaptive functioning. RESULTS: After controlling for demographic factors, the HT definitions predicted four outcomes, while the SFT definitions predicted three, and the EHT classifications contributed to the prediction of five child outcomes. The co-occurrence of multiple types of maltreatment was robustly related to outcomes. However, the HT and SFT classifications predicted outcomes even after accounting for the co-occurrence of multiple maltreatment subtypes. CONCLUSION: A classification scheme that differentiates between type combinations and single maltreatment types may have the greatest predictive validity. Over and above knowing about co-occurrence of maltreatment sub-types, it is important to understand what type, or constellation of types, of maltreatment have been alleged in a child's history.
