Relationship between private speech and performance in social problem solving task in preschool children

This study documented the developmental course of private speech and investigated the relationship between private speech and task performance in a social task. 40 Cantonese-speaking preschool children recruited were assigned into three groups (3-, 4- and 5-year-old). They were required to manipulate interaction partner’s mental state and propose solutions to cooperate or compete with the interaction partner in finding treasures. Task-irrelevant private speech was found to decrease with age while muttering and lip movement increased with age. Task-relevant private speech showed an inverted-U age pattern. Results also revealed a significant positive correlation between private speech and total solution scores (performance measurement), and insignificant correlation between private speech and total belief question scores (performance measurement). Implications and future directions were discussed.published_or_final_versionSpeech and Hearing SciencesBachelorBachelor of Science in Speech and Hearing Science

The Sociolinguistics of Code-switching in Hong Kong’s Digital Landscape: A Mixed-Methods Exploration of Cantonese-English Alternation Patterns on WhatsApp

This paper examines the prevalence of Cantonese-English code-mixing in Hong Kong through an under-researched digital medium. Prior research on this code-alternation practice has often been limited to exploring either the social or linguistic constraints of code-switching in spoken or written communication. Our study takes a holistic approach to analyzing code-switching in a hybrid medium that exhibits features of both spoken and written discourse. We specifically analyze the code-switching patterns of 24 undergraduates from a Hong Kong university on WhatsApp and examine how both social and linguistic factors potentially constrain these patterns. Utilizing a self-compiled sociolinguistic corpus as well as survey data, we discovered that those who identified as male, studied English, and had an English medium-of-instruction (EMI) background tended to avoid intra-clausal code-switching between Cantonese and English. Responses to the open-ended questions revealed that many of our participants used code-switching as a means to fill conceptual gaps, engage in socialization (e.g., to strengthen solidarity or make their speech sound more casual and natural), and construct bilingual and Hongkonger identities. Our findings shed some light on at least some of the locally embedded social meaning(s) of this linguistic practice in a digital context

Social work education as a catalyst for social change and social development: case study of a Master of Social Work Program in China

In response to the urgent need for professionally trained social workers to help in alleviating emerging social problems in China after the introduction of the market economy, the Hong Kong Polytechnic University and the Peking University launched a Master of Social Work (China) Program for social work educators in 2000, with the aim of developing a critical mass of social work educators to take up the future leadership in developing social work and social work education in China. To date, seven cohorts of over 230 students consisting of social work educators, NGO and government officials have been admitted to the program, and graduates of the program are playing a pivotal role in spearheading the development of social work education and fostering social development through the process. In this paper, the authors will present the vision and mission of the Master of Social Work (MSW) Program, the teaching and learning strategies adopted, and the ways in which the program has facilitated social change and social development through its educational process

On the Relationship between Resolution Enhancement and Multiphoton Absorption Rate in Quantum Lithography

The proposal of quantum lithography [Boto et al., Phys. Rev. Lett. 85, 2733 (2000)] is studied via a rigorous formalism. It is shown that, contrary to Boto et al.'s heuristic claim, the multiphoton absorption rate of a ``NOON'' quantum state is actually lower than that of a classical state with otherwise identical parameters. The proof-of-concept experiment of quantum lithography [D'Angelo et al., Phys. Rev. Lett. 87, 013602 (2001)] is also analyzed in terms of the proposed formalism, and the experiment is shown to have a reduced multiphoton absorption rate in order to emulate quantum lithography accurately. Finally, quantum lithography by the use of a jointly Gaussian quantum state of light is investigated, in order to illustrate the trade-off between resolution enhancement and multiphoton absorption rate.Comment: 14 pages, 7 figures, submitted, v2: rewritten in response to referees' comments, v3: rewritten and extended, v4: accepted by Physical Review
