Racial Equality and the Law: Creating an Effective Statute and Enforcement Model for Hong Kong
No full textThe Hong Kong government has commenced a public consultation exercise on a bill to prohibit racial discrimination, which is expected to be introduced in the Legislative Council in early 2005. The government has proposed to model the bill on the existing Sex Discrimination Ordinance (SDO) and the Disability Discrimination Ordinance (DDO). While there are advantages to adopting a familiar format, the author argues that the SDO and DDO can be improved upon, in particular, that a more flexible definition of indirect discrimination should be adopted and that special provisions be drafted to address discrimination against new immigrants from mainland China. The author takes the view that this is an opportune time to strengthen the enforcement model for all of Hong Kong's anti-discrimination laws. The author proposes that officers at the Equal Opportunities Commission (EOC) be empowered to take a more proactive approach and that a specialist equal opportunities tribunal should be established outside the auspices of the EOC.published_or_final_versio
The Failure of the Hong Kong Court of Appeal to Recognise and Remedy Disability Discrimination
No full textThis article critiques the recent decision of the Hong Kong Court of Appeal in Ma Bik Yung v Ko Chuen, the first case to be tried under Hong Kong's Disability Discrimination Ordinance. The Court of Appeal upheld the District Court's finding of disability harassment but granted the appeal from the finding of disability discrimination. The author argues that the Court erred, by introducing a hypothetical factual scenario that was inconsistent with the District Court's findings of fact and by failing to apply s3 of the Ordinance. The article also criticises the Court's holding that an 'unwilling' apology is outside the scope of remedies allowed by the Ordinance. In fact, similar statutory language is regularly used in Australia as the basis for orders to apologise. The author concludes by considering the potential conflict between the right to free expression and court-ordered apologies and suggests two possible approaches to the issue.published_or_final_versio

Tailoring Diffusion Dynamics in Energy Storage Ionic Conductors for High‐Performance, Multi‐Function, Single‐Layer Electrochromic Supercapacitors
No full textElectrochromic (EC) energy storage devices represent a cutting-edge technology visually indicating stored energy status in real time through color change. Herein, extremely simple single-layer electrochromic supercapacitors (SL-ECSs) based on energy storage EC ion gels are proposed. The operation of SL-ECSs follows Fick's law because of the diffusive nature of mass transport of all redox species. Therefore, the diffusion dynamics are tuned by tailoring fundamental parameters, the diffusion coefficient, and concentration gradient, and the availability of energy storage is maximized by reducing residual charges that cannot be extracted during the normal discharge process. In terms of the two critical metrics of ECSs, areal capacitance (C-areal) and transmittance contrast between charged and discharged states (Delta T), the performance of SL-ECSs (C-areal approximate to 43.0 mF cm(-2) and Delta T approximate to 96.8%) is favorably compared with previously reported ECSs. The capacitance retention remains at >80% even after continuous charge/discharge cyclic operations for 3000 min without specific encapsulation. Moreover, the practical multi-functionality of the SL-ECS is successfully demonstrated as a power source and applied force monitoring platform. It is expected that the SL-ECS will be a simple but versatile component of high-performance, ultra-small functional electronics.
Polymeric Ion Conductors Based on Sono‐Polymerized Zwitterionic Polymers for Electrochromic Supercapacitors with Improved Shelf‐Life Stability
No full textMonolithic electrochromic supercapacitors (ECSs) have attracted increasing interest in recent electrochemical electronics due to their simplicity and unique ability to visually indicate stored energy levels. One crucial challenge for practical use is the improvement of shelf-life. Herein, zwitterionic (ZI) ionogels are proposed as effective electrolytes to reduce the self-discharging decay of ECSs. All-in-one ZI electrochromic (EC) gels are produced by one-pot sono-polymerization. The presence of ZI moieties in the gel does not affect the EC characteristics of chromophores. In addition, excellent capacitive properties in areal capacitance and coulombic efficiency are presented owing to the alignment of ZI units under an electric field and the formation of ion migration channels where rapid ion transport is allowed. Furthermore, the shelf-life of the ZI gel-based ECS is significantly improved by adjusting the interaction between polymeric gelators and ion species. The ZI gel-based ECS is expected to be a key platform for future smart energy storage devices.
Criminal Due Process in Hong Kong and Singapore: A Mutual Challenge
No full textThis article explores what the author believes to be the fruitful task of comparing the divergent development of criminal due process jurisprudence in Hong Kong following the enactment of the Bill of Rights Ordinance and the Basic Law, with that in Singapore. Whilst Singapore cases have remained conservative, Hong Kong courts have begun to develop what promises to be a robust attitude toward due process issues. It is argued that the comparison between the two jurisdictions is especially apt given the many similarities between the peoples of Hong Kong and Singapore. The article also ventures to sketch out the predictive exercise of asking whether Singapore is likely to become more like Hong Kong, or whether it is Hong Kong which will move closer to Singapore
