Anti-triad legislations in Hong Kong: issues, problems and development

One way to tackle triad societies is through effective legislation. The present article first describes and reviews the legislation dealing with triad activities in Hong Kong – The Societies Ordinance – and highlights the main issues and problems. Four issues are discussed, namely ambiguity in the definition of triad membership, doubtful neutrality of triad experts, outdated triad-related literature cited in the court, and the contradiction with human rights and freedom of expression. The article further examines the effect of the ordinance in suppressing triad activities and argues that the law is not very effective in penalizing senior triad members, thus justifying the need for a new legislation to contain the growth of triad activities and organized crime.     

Joblessness and poverty in America's central cities: Causes and policy prescriptions

Abstract

Two paradigms pervade the policy debate on the causes of urban joblessness and poverty: (1) a structural, nonvoluntaristic perspective emphasizing the roles of urban economic change, residential segregation, and spatial and skills mismatches, and (2) a rational‐choice, voluntaristic perspective contending that the generosity and ready availability of welfare programs have removed the incentive for poor persons to accept low‐paying jobs. This article brings together propositions of each paradigm into a comprehensive theoretical model. The study measured and tested key causal operators of the model for a sample of 67 large U.S. cities, with special attention to race and gender.

Results show that structural and welfare disincentive perspectives are not in conflict but rather operate side by side to reinforce joblessness and poverty. Race and gender, especially the role of urban space for women's work, are important. The article raises pertinent policy issues derived from the two perspectives and from the analysis.     

Democratization in turmoil? Elections in Hong Kong

The first SAR Chief Executive, Tung Chee‐hwa, in his speech at the SAR Establishment Ceremony, said: ‘Democracy is the hallmark of a new era for Hong Kong. The SAR Government will resolutely move forward to a more democratic form of government in accordance with the provisions in the Basic Law’. Butler, Penniman and Ranney, however, cautioned that ‘the critical difference between democratic and nondemocratic regimes is to be found in whether or not they hold elections, and if they do, what kind’. Indeed, electoral changes made to the 1998 LegCo elections are found to be anti‐democratic and retrogressive, as well as unnecessary. The authors conclude that electoral systems matter because they are one of the central mechanisms in modern democracies to give substance and content to democratic governance. If electoral systems are designed in such a manner that they obstruct the exercise of popular sovereignty, ride rough‐shod over the principle of political equality, undermine the extent of representation, complicate relationships of accountability as well as delimit opportunities for participation, then such systems should have little place in genuine democratic reform. To bring Hong Kong's democratization forward, a hard look at the electoral system, which should be more informed by the principles and practices of democracy will be mandatory.     

Optimization of the separation of organic explosives by capillary electrophoresis with artificial neural networks

The separation of 12 explosives by capillary electrophoresis was optimized with the aid of artificial neural networks (ANNs). The selectivity of the separation was manipulated by varying the concentration of sodium dodecyl sulfate (SDS) and the pH of the electrolyte, while maintaining the buffer concentration at 10 mM borate. The concentration of SDS and the electrolyte pH were used as input variables and the mobility of the explosives were used as output variables for the ANN. In total, eight experiments were performed based on a factorial design to train a variety of artificial neural network architectures. A further three experiments were required to train ANN architectures to adequately model the experimental space. A product resolution response surface was constructed based on the predicted mobilities of the best performing ANN. This response surface pointed to two optima; pH 9.0-9.1 and 60-65 mM SDS, and pH 8.4-8.6 and 50-60 mM SDS. Separation of all 12 explosives was achieved at the second optimum. The separation was further improved by changing the capillary to an extended cell detection window and reducing the diameter of the capillary from 75 microm to 50 microm. This provided a more efficient separation without compromising detection sensitivity.     

Effects of self-concept and perceived disapproval of delinquent behavior in school children

It is argued that a multidimensional approach to self-concept may reveal intricate relations between self-concept and delinquent behavior, and that perceived approval of delinquent behaviors from referent groups may be related to the frequency of their occurrence. To evaluate these hypotheses, 1668 students from Grade 7 to Grade 9 responded to a questionnaire that measured their general self-esteem; their self-concept with regard to physical ability, social ability, physical appearance, and academic ability; the frequency they committed 15 delinquent acts; and the perceived approval of committing these acts from their parents, teachers, and friends. Regression analyses indicated that poor academic self-concept and poor relationship with school and parents were related to a higher frequency of delinquent behavior. However, a higher frequency of delinquent behavior was related to a more positive selfconcept with regard to social ability and physical ability. Finally, higher perceived approval from parents and peers was related to more delinquent behavior. Implications of these findings for identifying the antecedents and consequences of delinquent behavior were discussed.Received his Ph.D. from University of Illinois in social, industrial, and organizational psychology.

A Novel Solvent-based Method to Separate Duct Tape from Porous Surface for Fingerprint Development

In this study, we have proposed a novel solvent-based method using a specific concentration of 3M™ Novec™ HFE-72DE and 7200 solvents to untangle duct tape from porous article with minimal impact to the quality of latent fingerprint deposited on the sticky-side surface of duct tape. A series of experiments determined that a mixture of 30% HFE-72DE:7200 (v/v) was found to be the most effective to separate various brands of duct tape from different types of porous surface, including office copy paper, newspaper, cardboard, and tissue wipe, which had been stored for up to 30 days before untangling. Further studies also revealed that 30% HFE-72DE:7200 was compatible with three common fingerprint development methods for porous articles, namely ninhydrin, indanedione-zinc, and physical developer. The nonflammability and low toxicity nature of this novel solvent mixture also make it ideal for separating duct tape from porous surface in laboratory or at crime scene.     

Economic development and structural setting: Hong Kong electronics industry

A structural analysis of the economic development in developing economies is proposed. A development model is constructed and examined against the experience of the Hong Kong electronics industry. The proposed model indicated that the local structural settings of developing economies did not foster a high profit incentive and investment environment for rapid economic development. However, the same settings when integrated into an international structural context can generate a structural profit that is based on the difference in the cost of production. This structural profit can act as an engine of growth for the whole economy. The application of the model has shown that the calculation of the structural profit is not simply based on certain factors of production but on the overall cost of production. In addition, the application also indicated that three main aspects of the structural settings have played the determining role in shaping the development of the industry, namely, the export network, risk and uncertainty in the local structural settings and peripheral industries.
