A Hierarchical Approach to exploiting Multiple Datasets from TalkBank

TalkBank is an online database that facilitates the sharing of linguistics research data. However, the existing TalkBank's API has limited data filtering and batch processing capabilities. To overcome these limitations, this paper introduces a pipeline framework that employs a hierarchical search approach, enabling efficient complex data selection. This approach involves a quick preliminary screening of relevant corpora that a researcher may need, and then perform an in-depth search for target data based on specific criteria. The identified files are then indexed, providing easier access for future analysis. Furthermore, the paper demonstrates how data from different studies curated with the framework can be integrated by standardizing and cleaning metadata, allowing researchers to extract insights from a large, integrated dataset. While being designed for TalkBank, the framework can also be adapted to process data from other open-science platforms

Reanalyzing L2 Preposition Learning with Bayesian Mixed Effects and a Large Language Model

We use both Bayesian and neural models to dissect a data set of Chinese learners' pre- and post-interventional responses to two tests measuring their understanding of English prepositions. The results mostly replicate previous findings from frequentist analyses and newly reveal crucial interactions between student ability, task type, and stimulus sentence. Given the sparsity of the data as well as high diversity among learners, the Bayesian method proves most useful; but we also see potential in using language model probabilities as predictors of grammaticality and learnability

Values, priorities and responses: Comparing English headteachers' and Hong Kong principals' perceptions of their work

This article investigates the perceptions of English headteachers and Hong Kong principals on the kinds of pressures that they believed affected the way they did their job, and in particular the degree to which they felt their governments were affecting their leadership role. The research utilised semi-structured interviews to generate written ‘portraits’ of these individuals, which were then examined to answer questions about current pressures. The findings suggested that (1) there was considerable variation in the manner these individuals responded to key issues; (2) all individuals prioritised local concerns, and particularly with consideration to the children in their care; (3) there was a greater sense of embattlement from the English headteachers and a more critical approach to legislation, than from the Hong Kong principals, though with considerable individual variation in the degree of overt resistance shown; (4) whilst current educational reforms in Hong Kong seemed to favour the development of creativity more than those in England, there was within both national contexts evidence of the damaging effects of the pace and quantity of reforms

Embedded Librarians in the Classroom: A Case Study at HKUST Library

The introduction of new 4-year undergraduate program has unprecedented impacts on the curriculum design, pedagogies and student learning styles for higher education institutions in Hong Kong. In order to prepare for this challenging reform, the Hong Kong University of Science and Technology (HKUST) has strategically redeveloped its undergraduate curriculum. The new curriculum also emphasizes the student-centric approach, with new teaching initiatives to enhance students learning and personal development. Apart from equipping students with sound knowledge in specialized subject areas, graduates are also expected to develop high-level, transferable competencies including critical thinking, leadership, teamwork and information literacy. For many years, the Library has been offering information literacy instructions in all means through orientation programs, course-related classes, credit-bearing information literacy course, database workshops and web-based tutorials. To support the new pedagogical reforms, the Library must be proactive in promoting ourselves to faculty and students as their partners in teaching, learning and research. The librarians must also recognize users’ information needs and behaviors in order to deliver effective, relevant and creative services. In spring, 2011, two reference librarians were invited to join a newly developed engineering course; worked closely with undergraduate students and faculty on solutions to real world challenges throughout the semester. It was the first time HKUST librarians embedded in a course. This collaboration not only strengthened our relationship with faculty and students, it also helped us better understand the learning and information-seeking behaviors of our young generations, and gave us directions on what and how to support student learning in the future. This paper chronicles the faculty-librarian collaboration; follows by the discussion of emerging opportunities and challenges for embedded librarianship in one of the signature courses at the HKUST

Mainland Chinese Tourists’ Expectations, Perceived Performance of and Satisfaction towards Shopping Malls in Hong Kong

Tourists from mainland China constitute one of the world's biggest and fastest-growing travel markets. The Hong Kong Tourism Board expects the frequency of the mainland Chinese tourists to grow steadily. One of the beneficiaries of this phenomenon is Hong Kong’s shopping malls. However, understanding of tourists from mainland China’s expectations from, perceived performance of and satisfaction with the shopping malls’ attributes in Hong Kong is inadequate. This study intends to fill this important gap. A survey questionnaire was employed for data collection. The main results reveal the mainland Chinese tourists’ levels of satisfaction, indifference and dissatisfaction as well as the relationship between shopping malls’ attributes and customer satisfaction

Use of switching barriers to retain customers: Online retail stock traders in Hong Kong

Why some customers decide to stay withexisting service provider after having thought of switchinghas apparently not been examined adequately in extantresearch. The purpose of this research is to identifyfactors relevant to building constructs to representswitching barriers in online retail stock trading industryin Hong Kong. Review of extant literature, development ofa questionnaire and focus group interviews are the threeprincipal methods used for this research. Four factors thatare relevant for measuring switching barriers areidentified: two positive barriers involve service recoveryand trust and two negative barriers relate to higherswitching costs and lack of attractive alternatives

How can the R.E.N.A.L. nephrometry scoring system aid management of a solid renal mass?

OBJECTIVES. To investigate use of the R.E.N.A.L. nephrometry score in relation to the choice of treatment and postoperative complications for renal masses. DESIGN. Case series. SETTING. A tertiary referral hospital in Hong Kong. PATIENTS. Data of patients undergoing nephrectomy were collected retrospectively from a clinical database and analysed. A R.E.N.A.L. nephrometry score was allocated to each renal tumour by a blinded qualified radiologist, utilising computerised imaging systems. Patient demographics, choice of surgery (radical vs partial), and approaches (open vs minimally invasive) were analysed with respect to their R.E.N.A.L. score. RESULTS. In all, 74 patients were included during the study period, of which 38 underwent partial nephrectomy and 36 underwent radical nephrectomy. No differences between the groups were found with respect to patient demographics. There were significant differences between the partial and radical nephrectomy groups in terms of their mean nephrometry score (6.9 vs 9.3, P<0.001). The mean nephrometry sum was also significantly different in the open approach versus the minimally invasive approach in patients having partial nephrectomy (7.8 vs 6.0, P=0.001). There was no difference in the postoperative 90-day morbidity and mortality in the partial nephrectomy and radical nephrectomy groups. CONCLUSIONS. The R.E.N.A.L. nephrometry score of a renal mass correlated significantly with our choice of surgery (partial vs radical) and our approach to surgery (open vs minimally invasive surgery), particularly in the partial nephrectomy group. It does not, however, correlate with postoperative complications. The nephrometry score provides a useful tool for objectively describing renal mass characteristics and enhancing better communication for the operative planning directed at renal masses.published_or_final_versio

Gestational Exposure to Antidepressants and Risk of Seizure in Offspring: A systematic review and meta-analysis

In spite of the preliminary evidence suggesting a link between gestational use of antidepressant and neurodevelopmental disorders in their offspring, the association between maternal use of antidepressants during pregnancy and the risk of neurologically-related adverse outcomes such as neonatal seizure is still unclear. This study summarises the available evidence on the association between gestational exposure to any antidepressants and the risk of seizure in neonates and children. We found that gestational antidepressant exposure is associated with a 2.3-fold higher incidence of seizure in offspring. Although a causal relationship cannot be confirmed in view of other potential confounders, our findings warrant future research on related clinical aspects, and possibly more careful monitoring of foetal neurodevelopment in pregnant women taking antidepressants during pregnancy. However, this does not suggest the abrupt withdrawal of antidepressants during pregnancy for all cases at risk of seizure in offspring as this must be balanced with the risk of negative consequences caused by untreated maternal depression, and decision-making should be individualised for each patient
