Racial Equality and the Law: Creating an Effective Statute and Enforcement Model for Hong Kong
Full text linkThe 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
Full text linkThis 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

Sine-Gordon Equation and Quantum spin transport in one-dimension
No full text我研究一維自旋1/2反鐵磁系統的量子自旋傳輸機制. 我先將此自旋鏈轉換成費米子，再做玻色化近似。最後變成(雙) Sine-Gordon方程式，在第二章我證明解的等價性。考慮外場的變化，我加入絕熱相位並考慮在不同的邊界條件下此方程式的解。還原此解到原來的自旋鏈物理系統. 我觀察到在一般的固定邊界條件下有自旋=1通過整個系統。而此結論不同於一般的結論──自旋是由邊界態來傳輸。這寫在第三章。而在其他等價性不同的邊界條件下，自旋是累積在邊界。其機制不同於前，我也提出一個拓樸圖像。這是第四章的內容。最後在第五章，我利用Möbius轉換找到雙Sine-Gordon方程式含絕熱相位的數值精確解。在有限與無限系統，相對應解也有不同。另外我也討論微擾解的方法。We studied the spin transport mechanism in a S=1/2 antiferromagnetic chain. The spin chain is mapped into a fermion system, where equation of motion is transformed into a (Double) Sine-Gordon Equation ((D)SGE) with the approach of bosonization. We studied first, the non-interacting case. By varying adiabatically a phase angle ϕ which comes from external fields, the spin states change between the Néel state and dimer state and a quantized spin S=1 is transported by the bulk state from one end of the spin chain to the other. We have also considered the interacting case. I found that it is equivalent to the situation of twisted boundary condition. The spin states possess topological meaning. I also transform the solutions of SGE in Wazwaz [20] into another form we are familiar with. Finally, I use Möbius transformation to numerically solve asymmetric DSGE, which was not solved before.Table of contents:hapter1: Introduction (4).1: Quantum physics in one dimension and bosonization.1.1: Quantum physics in one dimension.1.2: Luttinger liquids and Bosonization.1.3: Construct soliton operator for the quantized Sine-Gordon Equation.2: Introduction of Sine-Gordon Equation.2.1 Traveling solution of Sine-Gordon Equation.2.2: The separability of Sine-Gordon Equation.2.3: Separable solution of Sine-Gordon Equation and its complex extension.2.3.2: complex extension.2.4: Exact N-Soliton Solitons of Sine-Gordon Equation.2.5: Algebraic Geometry ( finite-zone) solutions of Sine-Gordon Equationhapter 2: Sine-Gordon equation with asymmetric phase (22).1: Introduction.1.1: List Wazwaz’s solutions.2: Further study of the states of solitons.2.1: Mathematics calculation and lemmas.2.2: Conclusions and Results of this sectionhapter 3: Evident of spin pump through bulk state by solving (28)symmetric Sine-Gordon Equation.0: Introduction.1: Hamiltonian and Continuum field theoretical studies.2: Analysis of sine-Gordon equation on a finite chain.3: Detailed analysis of the static soliton case.3.1: The solutions fit the fixed boundary conditions and the energy.3.2: Other solutions with the same Ath, x0, energy.4: Spin transport.5: Spin transport phenomena connecting to source and drainhapter 4: Sine-Gordon Equation with twisted boundary condition (47).0:Introduction.1: Hamiltonian.2: Different views of relation between beta and Ath.3: Twisted boundary condition of Sine-Gordon Equation.4: Real solutions in the forbidden region.4.1: Arguments that the state in the forbidden region is real.4.2: The energy formula in twised boundary condition SGE.5: Another observation in the forbidden region.6: Arguments that the spin state in the forbidden region is edge statend the topology view of this case.7: Conclusionshapter 5: Asymmetrical double-sine-Gordon equation (59).1: Introduction:.2: Classical solutions of Double Sine-Gordon Equation.2.1: List of classical solutions of DSGE.2.2: List of energies of classical solutions in DSGE.2.3: A method to construct solutions and action E ofouble Sine-Gordon Equation.3: General Mathematical Analysis include easier case: eta<1/4.3.1: Potential analysis and related topi.3.2: The equation to be solved.3.3: Function form and equations for infinite systems.3.4: Particular problem occur in eta<1/4.3.5.Another method to solve asymmetric Double Sine-Gordon Equation:.3.6 Discuss and Conclusion of DSGE in an infinite system.4: asymmetric Double Sine-Gordon Equation in finite system (87).4.1: Equations of asymmetric DSGE in a finite system.4.2: The particular problem: two sets of parameters for theolutions in finite system.5: Perturbation method for approach 0:.5.1: Introduction:.5.2: Perturbation for a finite system.5.3: Three examples of perturbation method.6: Discussion and Conclusion of DSGE in an infinite and a finite systemhapter 6: Conclusions (105)ppendix A: Basic properties of Jacobi Elliptic Functionsppendix B: Periodic theorem of static soliton of SGEppendix C: Introdction to Moeferences

[[alternative]]The Land Cultivation and Formation of the Regional Characteristics in Nan-Zi-Sian river mid-stream region During the Japanese-Ruled Period
No full text[[abstract]]This thesis study land cultivation process from Ch’ing dynasty to Japanese-Ruled Period in Nan-Zi-Sian river mid-stream region, on the frontier of Kaoshiuang .In order to restructure the regional characteristics, we selected the power of Japanese-Ruled government in Taiwan and private Japanese corporations project to Nan-Zi-Sian river mid-stream region as the research objects.
The land cultivation before Japanese-Ruled in Nan-Zi-Sian river mid-stream region, was a process of long-term interaction between Contonese(客家人) and plain aborigines, and that of construction of different life-style in both shores of Nan-Zi-Sian river mid-stream. Despite the fact that Nan-Zi-Sian river mid-stream region had been developed for a long time , the high limitation of unstable natural environment and the characteristic of traditional self-subsistent economy, which compelled the phenomena as individual isolated settlement and scattered space.
After 1895, the colonialists accelerated a new growth of development of land cultivation in the mid-stream region. Modern cane-sugar refinery , camphor and afforestation enterprises established in this area. Moreover, after private Japanese corporations invested in mid-stream region, they not only had changed the land-use of the hillside around this area , but had controlled the land operation and agricultural activities. A crowd relationship also change.
Under the powerful control of new style land cultivation and enterprise , many landowners and gentry appeared. They became local leaders. Local leaders almost took charge of leaders of important social and economic organizations. The important social and economic organizations became the formation of space of jiezhuangmin, the space of jingchaguan , and the space of buluomin.With agriculture , market ,school ,traffic and police system developed, Nan-Zi-Sian river mid-stream region greatly was structured. Finally, this area had changed the frontier and established tightly contact to other regions.
