3D Scene Annotation for Efficient Rendering on Mobile Devices

This paper presents a new approach for efficient 3D rendering on mobile devices, where selective rendering can be achieved with the help of 3D scene annotation. By taking advantage of first person environments in most 3D applications, we are able to annotate the flooring details of the 3D space. This allows 3D environments to be interfaced using a higher level view of objects. With the higher level of scene understanding, it is possible to determine which 3D objects are not required for loading or rendering based on the viewer’s location and its surrounding constraints

CONSTRUCTING THE LANGUAGE IDENTITY OF A HONG KONG CHINESE LANGUAGE TEACHER: A NARRATIVE SELF-STUDY

This study examines the development of second language (L2) identity based on the author's personal experiences as a citizen of Hong Kong. Employing a narrative self-study method, the author explores how Hongkongers' perceptions of their language identities evolve over time. The study reveals that the author's own perception of L2 identities has changed due to shifting political and social contexts as she has taken on various roles throughout her life, including daughter, granddaughter, student, and teacher. By using Mandarin and English at different times, the author has gained a unique understanding of her language identity as a Hong Kong citizen. This research demonstrates that L2 identity is fluid and constantly evolving, adapting to roles and experiences, which in turn influence teaching practices.本研究透過探索香港教師的個人經歷，研究第二語言身份的發展和演變。透過自我敘說研究法，探討香港人如何隨著時間推移感知他們的語言身份的變化和連續性。研究亦探討個人的第二語言身份認同如何隨著生活角色轉換以及政治和社會環境的變化而改變，以及如何影響其教學實踐   Article visualizations

The Fee Sensitive Risk Exposures of Project Authorized Person in Hong Kong

Authorized Persons (AP) play a critical role in the design and construction of building works in Hong Kong. Under the Building Ordinance, design and construction of building works need to be coordinated and monitored by an AP registered with the Buildings Department. Professionally qualified Architects, Engineers and Surveyors are eligible to register as AP after completing the prescribed assessment. In addition, the project AP is often appointed by the project owner to be the project team leader. In these capacities, a project AP is exposed to various risks. This paper seeks to identify the fee sensitive risk exposures of project APs. Through an ANOVA study, these risks exposures are those due to liabilities under the Building Ordinance at the construction stage, those towards the third parties and the clients

Webtrust Sm (Version 3.0): Evidence On Consumers Demand For Assurance Services And CPAs Comparative Advantage

Modifications to Web Trust in version 3.0 allowing practitioners to issue an opinion on individual principles (e.g., privacy and security) enables WebTrust to compete directly against other assurance services. The success of the new strategy depends upon: (1) differences in assurance demand for the individual principles, and (2) perceptions that CPAs are the most trusted assurance provider. This study finds: (1) the need for assurance differs across individual WebTrust principles and depends upon transaction type, and (2) CPAs are not perceived to be the most trusted provider

The Moderating Effect of Third-Party Assurance on the Relationship Between CSR Disclosure and Investor Judgments

Abstract: Using a survey-based experiment, we investigate whether corporate social responsibility (CSR) disclosures can influence perceptions of corporate reputation and if these perceptions affect investors’ assessment of firms as attractive investments. After viewing CSR disclosures, participants were asked how they perceived the subject firm as a potential investment, and also how they assessed the firm’s reputation. Specifically, the subject firm’s CSR disclosure was manipulated to include either all-positive performance information or mixed information reporting that some CSR goals are not being achieved. A second manipulation divided disclosures into those that were based on information assured by a third-party and those that were not assured. Current MBA alumni and MBA students from an AACSB-accredited university were surveyed. The results supported the usefulness of assurance in promoting a positive firm image, particularly when only positive CSR performance information is reported. The effect of perceived corporate reputation on investment attractiveness was also found to be significant. Together, the findings suggest that when CSR disclosures are assured, they can positively influence investors’ assessments of corporate reputation, which in turn leads to greater investment attractiveness.

NEUROPROTECTIVE EFFECT OF ARTOCARPUS LAKOOCHA EXTRACT AND OXYRESVERATROL AGAINST HYDROGEN PEROXIDE-INDUCED TOXICITY IN SH-SY5Y CELLS

Objective: Artocarpus lakoocha Roxb. is a traditional medical plant native to Southeast Asia and used as a dried aqueous extract so-called puag haad. Its role (and its major ingredient, oxyresveratrol) as an antioxidant neuroprotectant were explored.Methods: Differentiated SH-SY5Y neuroblastoma cells in 96-well plates were challenged with 200 µM H2O2 for 4 h and either Trolox (100 µM), oxyresveratrol (5-100 µM), or puag haad (1.2-25 µg/ml) applied 2 h before H2O2 or for 20 h after H2O2 washout. Cell viability, mitochondrial function, intracellular ROS, and lipid peroxidation were assessed.Results: Continuous presence of both H2O2 and antioxidant reduced mitochondrial function by ~50% but only by 30% with antioxidant. Sustained 24 h H2O2 showed no recoveries with antioxidants. Cell viability was modestly restored when antioxidants accompanied H2O2 for 4 h and both washed for another 20 h, but little recovery of mitochondrial function even though antioxidants removed ROS and prevent lipid peroxidation. Antioxidants added for 20 h after H2O2 marginally improve mitochondria and modestly restore cell viability, but lipid peroxidation was completely reversed.Conclusion: These results show that mitochondrial protection was illusive, yet both tested compounds, puag haad and oxyresveratrol, improved cell viability and especially ROS levels and lipid peroxidation. The potency oxyresveratrol on the redox-sensitive expression of antioxidant enzymes and its pharmacokinetics suggests that oral puag haad could provide effective protection in transient neurodegenerative disease.Â

Suppression of the postoperative neutrophil leucocytosis following neoadjuvant chemoradiotherapy for rectal cancer and implications for surgical morbidity

Objective: The extent to which neoadjuvant chemoradio- therapy for rectal cancer influences postoperative morbid- ity is controversial. This study investigated whether this treatment suppresses the normal perioperative inflamma- tory response and explored the clinical implications. Method: Prospective databases were queried to identify 37 consecutive study patients undergoing definitive surgery following 5-FU ⁄ capecitabine-based chemoradio- therapy and 35 consecutive untreated control patients operated upon for rectal or rectosigmoid cancer. Preop- erative (< 10 days) and postoperative (< 24 h) neutrophil counts, along with morbidity data, were confirmed retrospectively. Univariate and multivariate analyses assessed the apparent effect of chemoradiotherapy on change in neutrophil count. The latter’s association with postoperative morbidity was then examined. Results: Sufficient data were available for 34 study and 27 control patients. Repeated-measures ANCOVA revealed significant differences between their periopera- tive neutrophil counts (P = 0.02). Of the other charac- teristics which differed between the groups, only age and tumour location were prognostically significant regarding perioperative change in neutrophil count. Accounting for relevant covariates, chemoradiotherapy was significantly associated with a suppressed perioper- ative neutrophil leucocytosis. Local postoperative com- plications affected 25 of 61 patients, who had lower perioperative neutrophil increases than their counter- parts (P = 0.016). Conclusion: Chemoradiotherapy appears to suppress the perioperative inflammatory response, thereby increasing susceptibility to local postoperative complications

“Hidden youth”: a critical study of socially disengaged young people in Hong Kong and Scotland

There has been growing interest in academic literature about young people who are marginalised and disengaged from society. This thesis focuses on young people in Hong Kong and Scotland who physically shut themselves in the bedroom and do not go outside for months and years on end. They are referred to as “hidden youth” in East Asia, and it has emerged as a topical social issue across the region in the past ten years. Previous research studying “hidden youth” (mainly in Japan and Hong Kong) highlights that there are structural barriers in contemporary society which could lead to young people becoming self-secluded. The young people are described as living reclusive and solitary lives, as they are excluded from participation in the labour market and education and disengaged from interactions with families and other communities, especially friends and peer groups. Hence, they are considered as “withdrawn” from society and disconnected from socialising. This thesis critically reflects on “hidden” young people’s sense of connectedness and “being social” based on their lived experience. It also draws on recent debates of the construction of the “social”, particularly in digital sociology, to shed light on the processes of socialising in the digital age. This study uncovered that how “hidden” young people socialise may in fact be heterogeneous. Variability in how they engage in interactions and participation in society was identified. There were also differences in their levels of solitude and loneliness. Hence, describing how the young people are “being social” could be more nuanced than previously thought. This also makes analysing them as “socially withdrawn” particularly problematic. This research uses a qualitative exploratory approach, looking comparatively across two contexts; 32 interviews were conducted with “hidden youth” in Hong Kong and Scotland. These two contexts are considered as instrumental examples, where social disengagements are especially prominent but discussed differently. The participants revealed various perceptions of hopelessness and lack of opportunities in work and education on the hand. This significantly affected their motivations to participate in employment and education; they could feel unable to fulfil their aspirations and become de-motivated. On the other hand, they were more interconnected with different groups of people in the digital world, and their interactions could be fluid. The space of the bedroom was highlighted as an important site where interactions could occur. This adds another dimension to consider how “hidden” young people interact, particularly with communities such as peer groups, friends and families. Moreover, digital interactions may also be important to how they socialise and experience a sense of connectedness. This highlights that there may be tensions in how young people’s motivations, as well as the opportunities they have, affect their engagements in digital and physical interactions. Therefore, this thesis argues that “hidden youth” could feel a sense of powerlessness towards hierarchical macro structures and meaninglessness towards interactions and participation in society. Conversely, they are relying on emerging digital social structures and networks to seek other forms of “being social”. Their high levels of digital interactions could in fact be a reaction to their experiences of unfulfilment in the labour market and in education. This thesis makes an important contribution to understand “hidden youth” and adds a more nuanced perspective to this emerging debate. In addition, it points to further aspects that should be taken into account in future studies to fully comprehend the sociality of a young person and its complexities in the digital age
