We present the first data on the vocalizations of large odorous frogs ( Odorrana graminea, previously Odorrana livida), from southern China. The males produce diverse broadband signals most of which contain ultrasonic harmonics. Six basic call-types were identified based on the number of call notes, fundamental frequency, call/note duration, frequency modulation patterns and spectral composition. O. graminea is one of only a few non-mammalian vertebrates able to detect ultrasound, but its tympanic membranes are not recessed. These results should stimulate further studies to provide new insights into the mechanisms underlying high-frequency communication in anurans. [ABSTRACT FROM AUTHOR]

Summary: Background/Purpose: According to the US National Kidney Foundation K/DOQI Guidelines in 2000, under most circumstances, spot urine samples should be used to detect and monitor proteinuria in children and adults and timed collection is often unnecessary. However, its use is still not widely implemented in Hong Kong. We aimed to assess the correlation of spot urine protein-to-creatinine (Pr/Cr) ratio to 24-hour urine protein excretion in our local setting. Methods: This was a prospective study set in regional hospitals in Hong Kong. A total of 174 patients were recruited from 2007 to 2008. Spot urine Pr/Cr ratio and 24-hour urine protein measurements were determined. Linear regression model was used to fit and test the relationship between 24-hour urine protein excretion and the spot urine Pr/Cr ratio. Results: Spot urine Pr/Cr ratio correlated well with 24-hour urine protein excretion (r = 0.95, p < 0.0001). Conclusion: Spot urine Pr/Cr ratio is a convenient, user-friendly and reliable method to replace 24-hour urine protein measurement for the assessment of proteinuria. 背景: 根據 2000 年美國國家腎臟基金會的 K/DOQI 指引，對於偵測及監察成人及兒童的蛋白尿，在大多數情況下採用隨機單次尿液檢體即可，毋須講究尿液收集的時間。然而，此措施在香港並未被廣泛應用。本研究之目的，是在香港的區域醫院內，測量病人隨機單次尿液之蛋白-肌酸酐 (Pr/Cr) 比例、及 24 小時之尿蛋白排泄量，並調查兩者的相關性。 方法: 研究採取前瞻性的方式，在 2007 至 2008 年間共納入 174 位病人，分別測量隨機單次尿液 Pr/Cr 比例及 24 小時尿蛋白排泄量，並以線性回歸法進行數據的分析。 結果: 結果顯示，隨機單次尿液 Pr/Cr 比例與 24 小時尿蛋白排泄量呈現顯著的相關性 (r = 0.95、p < 0.0001)。 結論: 在蛋白尿的評估上，作為一個簡便而可靠的指標，隨機單次尿液 Pr/Cr 比例理應可取代 24 小時尿蛋白排泄量。 [ABSTRACT FROM AUTHOR]

As part of a comprehensive research into PPP implementation, nine case studies were scrutinized to explore the critical risks influencing the success of PPP water projects in China. Eleven critical risks were identified from real-life risk events through the content analysis. They were further analyzed in the aspects of risk origin and their allocation mechanism. It has been found that the government risks are considered as the most critical risks encountered by the Chinese project practitioners. To allocate risk, industrial practitioners should not only take into account of their management capability, but they should also pay more attention to the overall balance of risks and benefits, and risk guarantee through rigorous contract structure. The findings presented here are believed to enable interested investors to better understand the risks of PPP water projects in China. [ABSTRACT FROM AUTHOR]

The article presents a study which examines the coping mechanisms used by information technology (IT) organizations to respond to rapid change IT in the U.S. and China. It analyzes the success of these mechanisms such as vendor support, education and training, endurance, and consultant support in the two cultures. It is found out that national culture can significantly affect the outcome of the use of these coping mechanisms.

Man-made land or islands that are reclaimed from the sea are suitable for building airports, harbors, and industry parks for material transportation because of their broad air and land spaces. However, the reclaimed foundation settlement process is of public concern, including the continuous impact of ocean processes on its stability. The majority of the buildings and facilities of Hong Kong International Airport (HKIA) are built on a reclaimed foundation. The reclaimed foundation has been in residual settlement since completion of the filling project in 1994. In this study, we use persistent scatterer interferometry (PSI) and ENVISAT (European Satellite) advanced synthetic aperture radar (ASAR) data to detect the residual settlement rates from 19 April 2006 to 9 January 2008. We use ground truth data to develop empirical correction models for correcting systematic biases in the ASAR PSI-detected settlement rates. The corrected data follow the Lorentz distribution well, implying that the residual settlement process is dominated by two modes or categories of settlement rates. The first category represents a relatively stable state and the second category represents a continuous settlement state. A ground settlement rate map of HKIA shows that an area of the Passenger Terminal Building and an area of the Southern Runway are two relatively stable areas. There are two major continuous settlement areas. One covers the airport Midfield. Another is along the coastline, implying that attention should be paid to impacts of ocean processes on the stability of airport foundations. [ABSTRACT FROM AUTHOR]

Abstract: The sorption/desorption characteristics of heavy metals onto/from soil particle surfaces are the primary factors controlling the success of the remediation of heavy-metal contaminated soils. These characteristics are pH-dependent, chemical-specific, and reversible; and can be modified by enhancement agents such as chelates and surfactants. In this study, batch experiments were conducted to evaluate the feasibility of using citric acid industrial wastewater (CAIW) to desorb cadmium from a natural clay from Shanghai, China at different soil mixture pHs. It can be observed from the results that the proportion of cadmium desorbed from the soil using synthesized CAIW is generally satisfactory, i.e., >60%, when the soil mixture pH is lower than 6. However, the proportion of desorbed cadmium decreases significantly with increase in soil mixture pH. The dominant cadmium desorption mechanism using CAIW is the complexion of cadmium with citric acid and acetic acid in CAIW. It is concluded that CAIW can be a promising enhancement agent for the remediation of cadmium-contaminated natural soils when the environmental conditions are favorable. As a result, CAIW, a waste product itself, can be put into productive use in soil remediation. [Copyright &y& Elsevier]

Abstract: This paper sheds an empirical light on port development patterns by discussing the structure and the development of the Yangtze River ports system. We argue that the Yangtze River system is going through a regionalization phase, mainly in relation to the port of Shanghai. This process started on the lower Yangtze but is now also moving upstream. The transition towards the port regionalization phase is typically a gradual and market-driven process that mirrors the increased focus of market players on logistics integration. This paper builds on the existing literature on port systems and adapts port development models to river ports. Furthermore, we employ some statistical techniques that are common to the analysis of port systems, and introduce some techniques that have not been used much by transport geographers in ports. This paper will address the dynamics in the Yangtze River ports system by analyzing the level of cargo concentration and the degree of inequality in operations of the container ports. The paper also assesses observed differences in development of ports in different areas along the river (upstream/downstream) and reflects on the role of ownership structures in shaping regional load centre networks.

Earlier research studies on public-private partnership (PPP) indicated that an objective, reliable, and practical risk assessment model for PPP projects and an equitable risk allocation mechanism among different parties are crucial to the successful implementation of these PPP projects. However, actual empirical research works in this research area are limited. This paper reports the first stage of a research study, which aims to identify and assess the principal risks for the delivery of PPP projects in China and to address their proper risk allocation between the private and public sectors. An empirical questionnaire survey was designed to examine the relative importance of different risk factors and to analyze the allocation of risk factors to different parties in PPP projects. A total of 580 questionnaires were sent out, and a total of 105 valid responses were obtained for data analysis. The Mann-Whitney U test is employed to investigate whether significant difference in perception existed first between the private and public sectors and second between industrial practitioners and academics in China. The empirical findings show that the three most important risk factors for PPP projects in China are (1) government intervention; (2) government corruption; and (3) poor public decision-making processes. These findings reveal that the Chinese government intervention and corruption may be the major obstacles to the success of PPP projects in China. A major cause for these risks may be attributed to inefficient legislative and supervisory systems for PPP projects in China. After conducting the Mann-Whitney U test on the 105 survey respondents, the empirical findings indicate that the perceptions of all 34 risk factors in China between the private and public sectors were not significantly different. Similarly, there were no significant differences between academics and industrial practitioners except that the former perceived the problem of government corruption to be more severe than did the latter. For risk allocation, the empirical results indicate that the public and private sectors were in general consensus with most of the risks identified. The major risks that the public sector preferred to accept are within the systematic risk category, especially political, legal, and social risks. The private sector preferred to retain the principal risks within the specific project risk category, especially construction, operation, and relationship risks, in addition to economic risks within systematic risk category. The remaining risk, environment risk, is preferred to be shared between the two sectors. This research study enables international construction companies to better understand how risks should be assessed and allocated for PPP projects in China. It also assists in risk response planning and control for future PPP projects in China. [ABSTRACT FROM AUTHOR]

Family is a central construct in Chinese life. Although central, it is also a changing construct as China becomes an increasingly international nation. This article discusses the Chinese family system in context, the challenges to existing constructs, and issues of cultural competence in the midst of change. Using diverse constructs such as pastoral care, existential ethics, and systemic approaches, it is possible to develop means of approaching family life in China both therapeutically and in a way that respects the freedom and dignity of a people in flux.

Abstract: This is the 9th Symposium on Electrokinetic Remediation. In Chinese, “9” is pronounced as “▪” which means longevity. As the first symposium of the series to be held on Chinese soil, it may be appropriate to follow the Chinese tradition so as to set the stage for the longevity of the symposium series. Therefore, it is time for us to recognize the milestone developments of past researchers, to clarify some of the myths, and to establish future research directions of electrokinetic remediation.

Based on daily maximum and minimum surface air temperature and precipitation records at 303 meteorological stations in China, the spatial and temporal distributions of indices of climate extremes are analyzed during 1961-2003. Twelve indices of extreme temperature and six of extreme precipitation are studied. Temperature extremes have high correlations with the annual mean temperature, which shows a significant warming of 0.27°C/decade, indicating that changes in temperature extremes reflect the consistent warming. Stations in northeastern, northern, northwestern China have larger trend magnitudes, which are accordance with the more rapid mean warming in these regions. Countrywide, the mean trends for cold days and cold nights have decreased by −0.47 and −2.06 days/decade respectively, and warm days and warm nights have increased by 0.62 and 1.75 days/decade, respectively. Over the same period, the number of frost days shows a statistically significant decreasing trend of −3.37 days/decade. The length of the growing season and the number of summer days exhibit significant increasing trends at rates of 3.04 and 1.18 days/decade, respectively. The diurnal temperature range has decreased by −0.18°C/decade. Both the annual extreme lowest and highest temperatures exhibit significant warming trends, the former warming faster than the latter. For precipitation indices, regional annual total precipitation shows an increasing trend and most other precipitation indices are strongly correlated with annual total precipitation. Average wet day precipitation, maximum 1-day and 5-day precipitation, and heavy precipitation days show increasing trends, but only the last is statistically significant. A decreasing trend is found for consecutive dry days. For all precipitation indices, stations in the Yangtze River basin, southeastern and northwestern China have the largest positive trend magnitudes, while stations in the Yellow River basin and in northern China have the largest negative magnitudes. This is inconsistent with changes of water vapor flux calculated from NCEP/NCAR reanalysis. Large scale atmospheric circulation changes derived from NCEP/NCAR reanalysis grids show that a strengthening anticyclonic circulation, increasing geopotential height and rapid warming over the Eurasian continent have contributed to the changes in climate extremes in China.

We examine the extent to which self-reported health and psychosocial health are affected by relative economic status in China, for the first time examining the importance of reference groups not defined by geographic location or demographic characteristics. We propose a methodology to address potential bias from subjective reporting biases and control for unobserved community characteristics. Analyzing a nationally representative data set from China, our findings support the relative deprivation hypothesis and suggest that relatives and classmates are salient reference groups for urban residents and neighbors are important for rural residents.

The concave-eared torrent frog, Odorrana tormota, has evolved the extraordinary ability to communicate ultrasonically (i.e., using frequencies > 20 kHz), and electrophysiological experiments have demonstrated that neurons in the frog's midbrain (torus semicircularis) respond to frequencies up to 34 kHz. However, at this time, it is unclear which region(s) of the torus and what other brainstem nuclei are involved in the detection of ultrasound. To gain insight into the anatomical substrate of ultrasound detection, we mapped expression of the activity-dependent gene, egr- 1, in the brain in response to a full-spectrum mating call, a filtered, ultrasound-only call, and no sound. We found that the ultrasound-only call elicited egr- 1 expression in the superior olivary and principal nucleus of the torus semicircularis. In sampled areas of the principal nucleus, the ultrasound-only call tended to evoke higher egr- 1 expression than the full-spectrum call and, in the center of the nucleus, induced significantly higher egr- 1 levels than the no-sound control. In the superior olivary nucleus, the full-spectrum and ultrasound-only calls evoked similar levels of expression that were significantly greater than the control, and egr- 1 induction in the laminar nucleus showed no evidence of acoustic modulation. These data suggest that the sampled areas of the principal nucleus are among the regions sensitive to ultrasound in this species. [ABSTRACT FROM AUTHOR]

An essay is presented on the controversy concerning exchange rate in China. It argues that excessive credit creation in the U.S. attributed to the international imbalance, which led to the country's account deficit in the early 1990s. It discusses the influence of sensitivity of the country's trade balances on price effects through exchange rate adjustments as well as highlights the factors responsible for China's large surpluses.

Childhood obesity prevalence amongst children is rising virtually in all countries with rapid acceleration in major cities in China. A cross-sectional study was conducted amongst 2,015 primary and secondary students in Macao to investigate the nutritional status and analyzed for the relationship of overweight and other cardio-metabolic risk factors. Subjects were randomly selected in proportion to the gender and age of the population. A total of 26.4% of boys and 13.9% of girls were overweight or obese with the highest prevalence around 40% among boys aged 9-12 and girls aged 10 and 11. Some 18.1% of boys and 20.4% of girls were found to have borderline LDL levels; a further 9.3% and 10.4% were found to have high-risk, respectively. For those students with overweight and obesity, a significant higher proportion of them had cardio-metabolic risk factors. Based on this evidence, there is a concern that obesity and its associated co-morbidity could reach epidemic proportions in the 'less industrialized' cities of China. [ABSTRACT FROM AUTHOR]

This paper presents an evaluation model useful for assessing the suitability of public-private partnership (PPP) projects by studying their attractive and negative factors. A survey of industrial practitioners in Hong Kong was conducted. Respondents were asked to rank the importance of 15 attractive and 13 negative factors for adopting PPP. From the rankings, relative weights of each factor were derived. The weights of these factors formed the basis for the evaluation model presented in this paper. The Hong Kong Zhuhai Macau Bridge was used to demonstrate how this evaluation model could be applied. From the list of attractive and negative factors the writers selected those that were foreseeable in this project. Calculating the total weights of each group of factors showed that negative factors outweighed attractive factors by 27%. The result indicated that PPP would not be a suitable method for delivering this project. The evaluation model presented in this paper can help both the public and private sectors to assess whether potential public projects are suited for PPP. [ABSTRACT FROM AUTHOR]

Background. GPs are often the first contact for injured children and hence play a crucial role in early identification and intervention of child abuse cases in the community.Objectives. To investigate Hong Kong GPs’ attitudes and behaviours towards child abuse reporting and their opinions on the introduction of a mandatory reporting system.Methods. A cross-sectional survey was conducted in 2006 among GPs who were attending or had attended a local postgraduate family medicine course.Results. One hundred and seventy-one GPs participated in this study, among which only 8.9% received formal child abuse training. Only 35.8% of those GPs who had encountered suspected cases reported every case. GPs who considered reporting could produce more harm than good to the family or child, who concerned about maintaining anonymity and who were reluctant to get involved with legal system were less likely to make a report [odds ratio (OR) 0.21–0.27; 95% confidence interval (CI) 0.06–0.11, 0.67–0.86]. ‘Concern on own anonymity’ was the only significant independent predictor for reporting (OR 3.47; 95% CI 1.11–10.87). Despite the low satisfaction with the present reporting system, 67.3% would not support the introduction of a mandatory reporting system. Logistic regression showed previous training could predict supportive attitude towards mandatory reporting (OR 4.84, 95% CI 1.01–23.27).Conclusions. This study shows low reporting behaviour among Hong Kong GPs. The major barriers to report are identified and can only be addressed by education and a carefully designed support system for GPs. Further research engaging a multidisciplinary approach is required to work towards an optimally beneficial system for the children. [ABSTRACT FROM PUBLISHER]

Purpose – This paper aims to investigate the operational mechanism, project performance, motives behind, benefits, difficulties and success factors of adopting the guaranteed maximum price (GMP) scheme based on a real-life case study of Chater House, an international Grade A private office project in Hong Kong. Design/methodology/approach – The case project was analysed by means of the related project documentation and a series of face-to-face interviews with the relevant senior project representatives. Findings – All the interviewed key project stakeholders perceived that the GMP contract helped achieve competitive price, value for money and superior quality of products as well as provided stronger incentives to innovation and cost saving. The case study revealed that the overall success of this GMP project was underpinned by several key attributes. Originality/value – The paper provides solid groundwork for client bodies and contracting organisations to develop a best practice framework for implementing successful GMP schemes in future construction.

The rationale, objectives and design of this study are described in this paper. [ABSTRACT FROM AUTHOR]

We ask how export demand shocks associated with the Asian financial crisis affected Chinese exporters. We construct firm-specific exchange rate shocks based on the precrisis destinations of firms' exports. Because the shocks were unanticipated and large, they are a plausible instrument for identifying the impact of exporting on firm productivity and other outcomes. We find that firms whose export destinations experience greater currency depreciation have slower export growth and that export growth leads to increases in firm productivity and other firm performance measures. Consistent with "learning-by-exporting," the productivity impact of export growth is greater when firms export to more developed countries. [ABSTRACT FROM AUTHOR]

Purpose - The purpose of this paper is to test the density dependence theory and explain the deep changes that the Chinese construction industry is experiencing. Focusing on both organizational level and industry level, it aims to identify the factors and to show how these factors affect the mortality of the Chinese construction companies. Design/methodology/approach - The Jiangsu construction industry is chosen as a proxy of the Chinese market. With the event history analysis method and life history data on all companies known to have operated during the period 1989-2007 in Jiangsu, an expanded Cox model is established to achieve the purpose. Findings - The construction industry level evolution plays an important role on exit rate of construction companies; however, this effect does not conform with density dependence as expected, and it interacts with organizational age. Besides, age and size of organizational level, and macro environment also act on mortality. Research limitations/implications - Owing to the difficulty in data acquisition, only 19 years of the Jiangsu construction industry have been reported here, which may not provide the whole picture of the evolution process. Furthermore, the different ending events, such as disbanding and merge, have not been identified, which may affect the results to some extent. Practical implications - The paper provides a new perspective to analyze the evolution of the Chinese construction industry and the mortality of construction companies. Originality/value - This is the first article that applies the density dependence theory to analyze the evolution process of the construction industry. It is also the first attempt to analyze the interaction of density, macro factors and organizational age, which is a contribution to the organizational ecology theory and the study of construction industry development.

Abstract: Introduction: The Government of the Hong Kong Special Administrative Region (SAR) has implemented different safety initiatives to improve the safety performance of the construction industry over the past decades. The Pay for Safety Scheme (PFSS), which is one of the effective safety measures launched by the government in 1996, has been widely adopted in the public works contracts. Both the accident rate and fatality rate of public sector projects have decreased noticeably over this period. Method: This paper aims to review the current state of application of PFSS in Hong Kong, and attempts to identify and analyze the perceived benefits of PFSS in construction via an industry-wide empirical questionnaire survey. A total of 145 project participants who have gained abundant handson experience with the PFSS construction projects were requested to complete a survey questionnaire to indicate the relative importance of those benefits identified in relation to PFSS. The perceived benefits were measured and ranked from the perspectives of the client and contractor for crosscomparison. Results: The survey findings suggested the most significant benefits derived from adopting PFSS were: (a) Increased safety training; (b) Enhanced safety awareness; (c) Encouragement of developing safety management system; and (d) Improved safety commitment. A wider application of PFSS should be advocated so as to achieve better safety performance within the construction industry. Impact on Industry: It is recommended that a similar scheme to the PFSS currently adopted in Hong Kong may be developed for implementation in other regions or countries for international comparisons.

Done correctly, cellulosic bioenergy should be both environmentally and economically beneficial. Carbon sequestration and decreased fossil fuel use are both worthy goals in developing next-generation biofuels. We believe that biotechnology will be needed to significantly improve yield and digestibility of dedicated perennial herbaceous biomass feedstocks, such as switchgrass and Miscanthus, which are native to the US and China, respectively. This Forum discusses the sustainability of herbaceous feedstocks relative to the regulation of biotechnology with regards to likely genetically engineered traits. The Forum focuses on two prominent countries wishing to develop their bioeconomies: the US and China. These two countries also share a political desire and regulatory frameworks to enable the commercialization and wide release of transgenic feedstocks with appropriate and safe new genetics. In recent years, regulators in both countries perform regular inspections of transgenic field releases and seriously consider compliance issues, even though the US framework is considered to be more mature and stringent. Transgene flow continues to be a pertinent environmental and regulatory issue with regards to transgenic plants. This concern is largely driven by consumer issues and ecological uncertainties. Regulators are concerned about large-scale releases of transgenic crops that have sexually compatible crops or wild relatives that can stably harbor transgenes via hybridization and introgression. Therefore, prior to the commercialization or extensive field testing of transgenic bioenergy feedstocks, we recommend that mechanisms that ensure biocontainment of transgenes be instituted, especially for perennial grasses. A cautionary case study will be presented in which a plant's biology and ecology conspired against regulatory constraints in a non-biomass crop perennial grass (creeping bentgrass, Agrostis stolonifera), in which biocontainment was not attained. Appropriate technologies that could be applied to perennial grass feedstocks for biocontainment are discussed. [ABSTRACT FROM AUTHOR]

Appropriate training can only be developed if training needs for specific skills are carefully identified. This paper, further to an aggregate model developed previously, aims to forecast the occupational share of the aggregate manpower demand for the construction industry of Hong Kong. The forecast, based on existing manpower statistics, is divided into two levels: broad occupations and detailed occupations. The broad occupational demand forecasting model is formulated using a time-series regression analysis to derive the relationship between the occupational share and the construction output cycle, technology, and various work-mix variables; whereas exponential smoothing technique is used to forecast the share of detailed occupations. This occupational demand estimation can provide solid information to facilitate manpower planning. It enables the policymakers to foresee the trends of occupational manpower demand and formulate policies and training and retraining programs tailored to deal effectively with the industry’s human resource requirements in this critical sector of the economy. Although the study focuses on developing models for the Hong Kong construction labor market, the adopted methodology can be applied in other labor markets to develop such models for manpower planning.

The article presents information on a study which determined the prevalence, diurnal symptoms and conditions associated with habitual snoring (HS) in primary school children. Study population were Chinese children aged 5 to 14 years recruited from 13 primary schools in two representative districts. A discussion on the research findings is detailed. Identifed risk factors were male sex, obesity, parental HS, atopic symptoms and history of upper respiratory infections. It was also observed that HS was associated with sleep-disordered breathing symptoms.

Equitable allocation of risks between the government and the private sector in concession agreement is essential to the success of public-private partnership (PPP) projects. The decision-making process, based on the established risk allocation principles expressed in linguistic terms, requires qualitative judgment and experiential knowledge of construction experts. However, it is subjective, partial, and implicit in actual application. This paper aims to develop a fuzzy synthetic evaluation model for determining an equitable risk allocation between the government and the private sector. By doing so, it assists the PPP project practitioners to transform the risk allocation principles in linguistic terms into a more usable and systematic quantitative-based analysis using fuzzy set. Twenty-three principles and influencing factors for risk allocation were identified through a comprehensive literature review. Nine critical risk allocation criteria (RACs) that evaluate the risk carrying capability of project participants were further identified, validated, and compiled based on the experts’ knowledge via face-to-face interviews. On the other hand, the weighting for each critical risk allocation criterion was determined through a two-round Delphi questionnaire survey. A set of knowledge-based fuzzy inference rules was then established to set up the membership function for the nine RACs. Based on the research findings, a fuzzy synthetic evaluation model was finally established to determine an equitable risk allocation between the government and the private sector.

Abstract: This study unveils causes of accidents in repair, maintenance, alteration and addition (RMAA) work. RMAA work is playing an increasingly important role in developed societies, including Hong Kong. Safety problems associated with RMAA work in Hong Kong has reached an alarming level. In view of rapid expansion of the RMAA sector and rising proportion of accidents in the construction industry, there is a pressing need to investigate causes of RMAA accidents. Structured interviews were conducted with RMAA contractors to explore causes of accidents in the RMAA sector. A two-round Delphi method with 13 safety experts was subsequently employed to verify the interview findings and rank the relative degree of importance for various causes of accidents. Accidents happen in RMAA work due to intersection of reasons. One of the root causes of accidents in RMAA works is low safety awareness of RMAA workers; however, wider organizational and industrial factors are not negligible. This study sheds light on why accidents happen in the RMAA sector. Only when the factors leading to accidents are identified can effective measures be made. [Copyright &y& Elsevier]

The Tibetan Plateau (TP) with an average elevation of over 4,000 m asl is the highest and most extensive highland in the world. We used monthly mean sunshine duration from the Chinese Meteorological Administration to examine the spatial and temporal variability of sunshine duration at 71 stations with elevations above 2,000 m asl in the eastern and central TP during the 1961–2005 period. The temporal evolution of the mean annual sunshine duration series shows a significant increase from 1961 to 1982 at a rate of 49.8 h/decade, followed by a decrease from 1983 to 2005 at a rate of −65.1 h/decade, with an overall significant decrease at a rate of −20.6 h/decade during the whole 1961–2005 period, which is mainly due to the summer and spring seasons. This confirms the evidence that sunshine duration in the TP ranges from brightening to dimming in accordance with sunshine duration trends in the rest of China. The surface solar radiation downwards from ERA-40 reanalysis data in the same region confirms the brightening/dimming phenomenon shown by the sunshine duration before/after the 1980s. Otherwise, additional climatic variables such as low cloud amount, total cloud amount, precipitation, relative humidity and water vapor pressure, in most cases, exhibit significant negative correlation with sunshine duration in the TP on an annual and seasonal basis before and after 1982, respectively. The trends of these variables suggest that changes in some of them might be related to the brightening and dimming detected with the use of sunshine duration measurements over the TP. We also hypothesize that the impact of anthropogenic aerosols upon the climatic variables analyzed cannot be rejected, especially in the significant increase in low cloud cover since approximately 1980.

The Hong Kong Bill of Rights Ordinance (BORO) guarantees many fundamental rights to Hong Kong's permanent residents. In these constitutionally significant statutes, two types of rights exist: 1) textually qualified rights, which contain qualifying language indicating for what purposes a legislated restriction is permissible, such as when necessary for national security, public order, public health or morals, and 2) textually absolute rights, which contain no language indicating when a legislated restriction on that right is permissible. In Leung Ksvok Hung & Others v. HKSAR, the Hong Kong Court of Final Appeal formulated a rationality requirement for when restrictions are constitutionally valid. The Court held that the rationalily requirement is derived from the word "necessary" in qualifying language in the BORO Article considered by the Court. First, this comment argues that subsequent courts have misapplied Leung Kwok Hung's formulation of the rationality requirement when considering textually absolute BORO rights that do not contain the word "necessary." Second, this comment analyzes two possible approaches to correcting this misapplication by constitutionally authorizing the rationality requirement for textually absolute rights in a manner not reliant on the word "necessary." This comment ultimately argues that the second approach, implying the rationality requirement into the BORO, should be followed. [ABSTRACT FROM AUTHOR]

In Europe, legislation about waste of electrical and electronic equipment (WEEE) recovery and recycling has been introduced in 2002, and corresponding legislation in the EU Member States was in place in August 2005 (EU-EC ). In the same period, China has been developing WEEE regulation as well. The main contribution to date to the Chinese legislative framework is the ‘Circular Economy Promotion Law of the People’s Republic of China’ that was approved on August 29, 2008, and came into force as of January 1, 2009. Both these legislative systems contain the Extended Producer Responsibility as a core concept, as well as a formal, and, in the case of China, centralised, recovery system. Given the conceptual similarities of legislation on WEEE, but striking differences in the product recovery systems in China and the EU, it is of interest to investigate if the existing recovery and recycling system in China actually fits the new legislation. Currently, there is anecdotal evidence that, in China, much of the WEEE flows into informal recycling channels such as secondhand market and manual recycling workshops. Not much is known otherwise because a formal governance system and official statistics collection do not exist yet. More particularly, the actual WEEE flow in China, or in particular cities, is virtually unknown, as is the relationship between collection, treatment, re-selling and disposal. This paper suggests a Markov chain model that allows for the analysis of the flow of WEEE through the reverse chain from point of collection through to final disposal. We analyse this system in its equilibrium state and investigate the impact of scenarios that reflect key elements of the new WEEE regulation in China. In addition, we offer a qualitative analysis of the various scenarios for the three dimensions of sustainability: people, planet and profit. This research offers specific suggestions to strengthen the Chinese WEEE recovery and recycling system that would bring the actual system more in line with the current policy. [ABSTRACT FROM AUTHOR]

China has witnessed a rapid increase in waste electrical and electronics equipment (WEEE) in the recent years, but has not yet established corresponding recycling and disposal systems with appropriate administrative oversight. Consequently, most household waste appliances have neither been effectively recycled nor safely treated. However, efforts were made to improve the situations. Reviewing the history of China's legislation in this field since the 1990s, this paper affirms China's recent achievements in the last few years with commentary on several of the latest regulations and laws. Through the research on WEEE recycling chain and related laws, the authors first analyze the significant impact this legislation has imposed on manufacturing, recycling, treatment, and exportation/importation in China's household appliance industry. Secondly, the authors indicate various difficulties in the implementation of the newly made laws and regulations. Finally, the authors propose several practical suggestions with regard to promoting the implementation of these laws and regulations, based on the existing state conditions and the experience of other countries in the recycling industry, such as those of European countries, America, and Japan.

The Tibetan Plateau, with an average elevation of over 4000 m above sea level, is the highest and most extensive highland in the world. Between 1980 and 2005, the annual mean temperature has warmed at the rate of 0.38°C decade-1. However, little attention has been paid to the variation of wind speed, the most important factor controlling evapotranspiration in the Tibetan Plateau. Here we used monthly mean wind speed from the Chinese Meteorological Administration data set to examine the spatial and temporal variability of wind speed at 71 stations (with elevations above 2000 m above sea level) in the eastern and central Tibetan Plateau during 1980-2005, and compared wind speed climatology and their trends with NCEP and ERA-40 reanalyses in the same domain. Compared with surface stations, NCEP overestimates wind speed and ERA-40 underestimates it, with mean annual biases of 0.93 m s-1 for NCEP and -0.75 m s-1 for ERA-40. Both surface stations and NCEP reanalysis show significant decreasing trends, at rates of -0.24 and -0.13 m s-1 decade-1, respectively, mainly evident in spring and summer. ERA-40 fails to capture any decrease. The above results indicate that NCEP captures wind speed better than ERA-40. We speculate that the most likely cause of diminishing wind speed are the asymmetrically decreasing latitudinal surface temperature and pressure gradients over the Tibetan Plateau, which may be part of a large-scale atmospheric circulation shift.

With the rapid growth of the Chinese economy, the desperate demand for infrastructure developments has created bottlenecks in the country’s sustainable development. Infrastructure investment could not be funded completely by the government alone. Taking Beijing as an example, there will be about 2,400 infrastructure projects to be developed during 2006–2010 with a total investment of over RMB 470 billion, which may impose budgetary pressure on the government. As a result, public-private partnership (PPP) could be considered as a favorable option to help provide these rapidly demanded public works and services. In order to investigate the potential for adopting PPPs in the People’s Republic of China, this paper aims to explore the critical success factors (CSFs) necessary to conduct PPP projects. The views from Chinese experts were collected via an empirical questionnaire survey. The respondents were invited to rate a total of 18 CSFs that contribute to the success of PPP projects as gleaned from the contemporary literature. The results of this survey were analyzed by the factor analysis technique. The findings showed that the 18 CSFs could be grouped into five underlying factors including: Factor 1—stable macroeconomic environment; Factor 2—shared responsibility between public and private sectors; Factor 3—transparent and efficient procurement process; Factor 4—stable political and social environment; and Factor 5—judicious government control.

Purpose - The Hong Kong Special Administrative Region (hereinafter referred to as Hong Kong) is an international leading commercial hub, particularly in Asia. In order to keep up its reputation a number of large public works projects have been considered. Public-private partnership (PPP) has increasingly been suggested for these projects, but the suitability of using this procurement method in Hong Kong is yet to be studied empirically. The purpose of this paper is to specifically consider whether PPPs should be used to procure public works projects in Hong Kong by studying the attractive and negative factors for adopting PPP. Design/methodology/approach - As part of this study a questionnaire survey was conducted with industrial practitioners. The respondents were requested to rank the importance of 15 attractive factors and 13 negative factors for adopting PPP. Findings - The results found that in general the top attractive factors ranked by respondents from Hong Kong were efficiency related: these included "Provide an integrated solution (for public infrastructure/services)", "Facilitate creative and innovative approaches", and "Solve the problem of public sector budget restraint". It was found that Australian respondents also shared similar findings to those in Hong Kong, but the UK respondents showed a higher priority to those economic driven attractive factors. Also, the ranking of the attractive and negative factors for adopting PPP showed that on average the attractive factors were scored higher than the negative factors. Originality/value - The results of this research have enabled a comparison of the attractive and negative factors for adopting PPP between three administrative systems. These findings have confirmed that PPP is a suitable means to procure large public projects, which are believed to be useful and interesting to PPP researchers and practitioners.

This study investigated whether the consumption of fruit and vegetable by Chinese primary students in Hong Kong is associated with their mother's (1) nutrition knowledge on fruit and vegetables; (2) attitude towards healthy eating; and (3) fruit and vegetable consumption. Fourth- and fifth-grade students from 10 primary schools located in different districts, along with their mothers, were invited to each fill-in a questionnaire related to their diet intake. Accomplished questionnaires were matched and analysed. There were 1779 mother–child pairs who were successfully matched. Chi-square analysis revealed that students' fruit consumption is associated with their mother's (1) knowledge on fruit and vegetables ( P = 0.006); (2) attitude towards healthy eating ( P = 0.010); and (3) fruit consumption ( P < 0.001). Students' vegetable consumption exhibited the same association with their mother's (1) knowledge ( P < 0.001), (2) attitude towards healthy eating ( P = 0.005), and (3) vegetable consumption ( P < 0.001). Logistic regression showed that knowledge, attitude and dietary practice of mothers were independent factors associated with the consumption of fruit and vegetables by students and are not influenced by the level of education and household income. The results highlight the important role of parents in promoting fruit and vegetable consumption to primary students. It reaffirmed the importance of parent nutrition education in the formulation of a comprehensive health promotion strategy to school-aged children. [ABSTRACT FROM AUTHOR]

The pollen and spores of the Wuyun Formation (Danian, Early Paleocene) from Jiayin County, Heilongjiang Province, Northeast China, are studied in this paper. The Danian vegetation at Wuyun was composed of mixed temperate and subtropical broad-leaved forest, with an admixture of conifers. The climatic parameters, obtained by the Coexistence Approach based on the palynological and megafossil data, are Mean Annual Temperature of 14.8–16.8°C, Mean Annual Precipitation of 815.8–1,571.8 mm. Combining other climatic parameters in the Tertiary, we obtained the latitudinal temperature gradients: 0.24 in Paleocene, 0.1 in Eocene, 0.45 in Miocene and 0.55 in Pliocene, in the area of East Asia. All these values and modern latitudinal gradient of 0.7 suggest a climatic transition from Paleocene to today: the temperature at higher latitudes first increased then decreased gradually during last 65 Ma, while it changed slightly in lower latitudes.

Hong Kong has been one of the early jurisdictions to adopt Public Private Partnership (PPP) model for delivering large public infrastructure projects. T he development of this procurement approach in Hong Kong has followed an intricate path . As such, it is believed that there are a number of areas which are interesting to unveil . As part of a comprehensive research study looking at implementing PPPs, interviews with experienced local industrial practitioners from the public sector were conducted to realize their perspective on the topic of procuring public works projects . Amongst these interviews, fourteen were launched government officials and advisers . The interview findings show that the majority of the Hong Kong and Australian interviewees had previously conducted some kind of research in the field of PPP. Both groups of interviewees agreed that "PPPs gain private sector's added efficiency/expertise/management skills" when compared to projects procured traditionally. Also, both groups of interviewees felt that projects best suited to use PPP are those that have an "Economic business case". The interviewees believed that "Contractor's performance" could be used as key performance indicators for PPP projects. A large number of critical success factors were identified by the interviewees for PPP projects; two of these were similar for both groups of interviewees. These included "Project objectives well defined" and "Partnership spirit/commitment/trust". Finally it was found that in-house guidance materials were more common in the organizations of the Australian interviewees compared to the Hong Kong ones. This paper studies the views of the public sector towards the topic of PPPs in Hong Kong and Australia, which helps to answer some of the queries that both academics and the private sector in these jurisdictions are keen to know. As a result the private sector can be more prepared when negotiating with the public sector and realise their needs better, academics on the other hand are provided a wider perspective of this topic benefiting the research industry at large.

Using data from recent surveys of migrants and local residents in ten cities in 2005, this paper examines how migration influences measurements of urban poverty and inequality in China, and also compares how other indicators of well-being differ for migrants and local residents. Contrary to previous studies that report that the income poverty rate of migrant households is 1.5 times that of local resident households, we find relatively small differences in the poverty rates of migrants and local residents. Although the hourly wages of migrants are much lower than those of local residents, migrant workers work longer hours and have lower dependency ratios and higher labor force participation rates. Including migrants increases somewhat measures of urban income inequality. Significant differences between migrants and local residents are found for non-income welfare indicators such as housing conditions and access to social insurance programs. [ABSTRACT FROM AUTHOR]

Patents for Chinese herbal medicines can be difficult to obtain. When the active ingredients of an herbal formula are known, danfang (single herb prescriptions) is better protected with quantified composition claims. When the active ingredients are unknown, 'product by processing', 'method of processing', 'method of administration' and 'new use claims' are often powerful tools to distinguish a traditional danfang from 'the prior art'. Additional patents may also be filed continuously in the product development process. Existing patents for fufang (composite prescriptions) are primarily drafted to protect traditional herbal formulations. More efforts are needed to protect various herbal combinations and their multiple applications. [ABSTRACT FROM AUTHOR]

A number of risk factors including obesity, insufficient consumption of fruits and vegetables, and lack of physical activities are responsible for the majority of chronic disease burden. Healthy behaviours should begin early in life with sustained actions, but in many countries there is no system addressing positive health. The opportunities offered by different settings for gaining entry into individuals and groups are of paramount importance for health promotion. Evidence has shown the effectiveness of the Healthy School model to improve healthy eating and physical activities. In this article we report key findings of studies in Hong Kong showing changes in school policies and environment in relationship to student health apart from improvement of health behaviours by adopting the Healthy School framework. A case study has illustrated how the framework created a supportive environment, policies changes, and personal health skills development to improve healthy eating. The Healthy School model can help to combat childhood obesity. [ABSTRACT FROM AUTHOR]

Public-private partnership (PPP) has been practiced for quite some time around the world and there are numerous infrastructure, construction, and building projects which are employing the concepts. Unfortunately, not all of these PPP projects are equally successful and some of these projects have been exposed to formidable obstacles. The need to identify potential obstacles for PPP projects is therefore becoming an important issue for both research and practice. Despite the amount of interest vested in PPP, it is normally the advantages of PPP that are touched on rather than the potential obstacles. Both Beijing and the Hong Kong Special Administrative Region (referred to as Hong Kong from here onwards) have been keen to introduce more PPP projects. This paper presents part of the findings of an empirical questionnaire survey in relation to the prevailing barriers to PPP success conducted in these two administrative systems. It was anticipated that the obstacles would be similar for these jurisdictions. Respondents were asked to rate the level of severity of thirteen potential obstacles toward PPP projects identified from a literature review. The top three obstacles rated by the Beijing respondents were found to be “lengthy delays in negotiation,” “lack of experience and appropriate skills,” and “lengthy delays because of political debate.” Similarly the first and third obstacles ranked by the Beijing respondents were also ranked within top three by the Hong Kong respondents, together with “very few schemes have actually reached the contract stage (aborted before contract).” It was also discerned that “less employment positions,” “reduce the project accountability,” and “high project costs” were all ranked bottom by both of the Beijing and Hong Kong respondents. Moreover, the results obtained in the United Kingdom reported in other studies also shown consistency with those of Beijing and Hong Kong. Therefore the research hypothesis was proved to be true. Although the importance of the obstacles was similar it was realized that the scores obtained in the United Kingdom survey were much lower. This observation showed that the British respondents were less threatened by the obstacles, probably due to the fact that they are much more experienced and confident in undertaking PPP projects compared to Beijing and Hong Kong. Further analysis of the data reflected that the responses within each administrative system were consistent as revealed from the Kendall’s concordance analysis. Although the Spearman rank correlation test indicated that there was no significant disagreement on the rankings of obstacles between respondents of the two administrative systems, considerable difference was detected by the independent two-sample t-test in the mean value of their responses between the two administrative systems for the two obstacles lack of experience and appropriate skills and lengthy delays in negotiation. In Beijing, respondents felt that lack of experience and appropriate skills were highly important ranking it second place, but in Hong Kong this obstacle was ranked eighth, showing their confidence in experience and skills. For lengthy delays in negotiation, although the ranking between Beijing and Hong Kong was similar the difference in score showed a large variation. This represents a difference in tendering procedures between the two administrative regions. Triangulation with real cases largely supports the survey findings. [ABSTRACT FROM AUTHOR]

Background: Childhood and adolescence are critical periods of habit formation with substantial tracking of lifestyle and cardiovascular risk into adulthood. There are various guidelines on recommended levels of physical activity in youth of school-age. Despite the epidemic of obesity and diabetes in China, there is a paucity of data in this regard in Chinese youth. We examined the association of self-reported level of physical activity and cardiovascular risk in Hong Kong Chinese youth of school-age.Methods: This was a cross-sectional study conducted in 2007-8 in a school setting with 2119 Hong Kong Chinese youth aged 6-20 years. Physical activity level was assessed using a validated questionnaire, CUHK-PARCY (The Chinese University of Hong Kong: Physical Activity Rating for Children and Youth). A summary risk score comprising of waist circumference, blood pressure, fasting plasma glucose and lipids was constructed to quantify cardiovascular risk.Results: In this cohort, 21.5% reported high level of physical activity with boys being more active than girls (32.1% versus 14.1%, p < 0.001). Regression analysis showed physical activity level, sex and pubertal stage were independently associated with cardiovascular risk score.Conclusion: Self-reported level of physical activity is associated with cardiovascular risk factors in Chinese youth after adjusting for sex and pubertal stage.

Abstract: Research into partnering performance measures for building and construction projects becomes crucial because a growing trend of client organizations has been observed to adopt partnering approach to procure their projects worldwide over the past decade. Although there are some related research studies and papers documented on this research area, few, if any, comprehensive and systematic research studies focus on developing a comprehensive, objective, reliable and practical performance evaluation model for partnering projects in construction. A Partnering Performance Index (PPI), which is composed of seven weighted Key Performance Indicators (KPIs), has been developed to measure, monitor, improve, and benchmark the partnering performance of construction projects in Hong Kong. A set of Quantitative Indicators (QIs) and well-defined ranges of Quantitative Requirements (QRs) for each QI have been further established using the Delphi survey technique and Fuzzy Set Theory. Evaluation of partnering success can now be based on quantitative evidences, thus tackling the subjectivity of performance evaluation. By making use of the Internet and database technology, PPI can be monitored on-line, thus saving much time, cost and efforts on data collection and retrieval than if they are done manually. As such, an Internet-based computerized partnering monitoring and benchmarking tool, namely the Computerized Partnering Performance Index System (CPPIS) has been developed. The Internet-based CPPIS enables project participants to input data at any time and location and the project administrators could perform data analysis via the Internet. The CPPIS also enables project managers to measure, monitor, improve and benchmark their partnering performances against those already stored in the database. Graphical presentations of data and various performance measures are also built in to assist various end-users to identify problematic areas and critical success factors for achieving partnering excellence.

The private sector has long been involved in delivering public sector projects, whether its role has been as a partner or just as a contractor for the government. Over recent years the interest in adopting public private partnerships (PPPs) has increased internationally. Many research studies have presented positive reasons for the governments and the private sector to welcome this form of procurement, rather than continue adopting the traditional options. This paper aims to explore and compare the key drivers for adopting PPP in China and the Hong Kong Special Administrative Region (referred to as Hong Kong from here onwards). An empirical questionnaire survey was conducted in both of these administrative systems and survey respondents were invited to rate their perceptions on the importance of 15 different drivers identified. Eighty-seven completed survey questionnaires were returned for analysis. The findings indicated that respondents from China rated economy-related drivers higher, whereas Hong Kong respondents tended to rate efficiency-related drivers higher. China’s demand for more public infrastructure and services has imposed great pressure on the government’s budget, and therefore economic drivers were rated higher. On the other hand, with adequate financial reserve in hand and budget surplus over recent years, Hong Kong has tended to prefer paying for projects upfront, and hence efficiency was regarded more significantly. Among the 15 drivers, both of the respondents from China and Hong Kong selected, “provide an integrated solution (for public infrastructure/services)” and “solve the problem of public sector budget restraint” to be within the top three drivers. Despite the general agreement on the ranking pattern, the results of independent two-sample t-test showed that China and Hong Kong shared very different views on the driver “reduce the total project cost.” This driver was ranked rather high by the mainland Chinese respondents, but much lower by the Hong Kong respondents. This finding can be construed that economic drivers are in general rated higher in China as compared to that in Hong Kong. [ABSTRACT FROM AUTHOR]

Abstract: We present new anatomical information showing that Koutalisaurus kohlerorum, from the Maastrichtian of Lleida Province, northeastern Spain, is most probably the junior synonym of Pararhabdodon isonensis from the same region. Dentary and maxillary characters previously considered as autapomorphies of K. kohlerorum and P. isonensis, respectively, are shown to be synapomorphies uniting the latter with Tsintaosaurus spinorhinus from the Campanian of the Wangshi Group, Shandong Province, China. This study provided conclusive evidence of the presence of the Lambeosaurinae in Europe. Tsintaosaurus spinorhinus and Pararhabdodon isonensis were inferred to form a clade of basal lambeosaurines characterized by a maxilla with an elevated articular facet for the jugal (continuous with the ectopterygoid ridge) and an extremely medially projected symphyseal region of the dentary. This clade originated in Asia during the middle or late Campanian. Pararhabdodon isonensis or its ancestors migrated from Asia to the Iberian island of the European archipelago. Reconstruction of ancestral areas by Fitch parsimony attributes the European occurrence of P. isonensis to a single dispersal event from Asia no later than middle to late Campanian.

Dividing China into seven regions reveals rural income and consumption divergence for both 1980–2005 and 2000–05. But while real rural consumption growth averaged 7.7 percent over 1985–2005 in the eastern coastal region, it averaged 6.5 percent uniformly in the interior. In evaluating well-being, such rapid improvement in all regions arguably overshadows negative connotations of divergence. Twenty years of household survey data reveal dramatic increases in rural household savings, as rural consumption improved more slowly than income in some periods. This raises questions about the suitability of consumption as a basis for measuring well-being and its distribution. Increased savings appear to be transient, as some households save while others dissave to purchase durables and afford lumpy services like education and healthcare—supplies of which became more plentiful in the 1990s. The paper argues that more meaningful measures of regional disparities come from differences in regional poverty headcounts. It also suggests that higher regional inequality and accompanying interregional migration indicate that inequality plays an important positive role in inducing economic actors voluntarily to move to more productive locations and activities as a mechanism for ensuring sustainable improvements in individual well-being.

Objectives: (1) To examine the validity of existing prediction equations (PREE) for estimating resting energy expenditure (REE) in obese Chinese children, (2) to correlate the measured REE (MREE) with anthropometric and biochemical parameters and (3) to derive a new PREE for local use. Design: Cross-sectional study. Subjects: 100 obese children (71 boys) were studied. Measurements: All subjects underwent physical examination and anthropometric measurement. Upper and central body fat distribution was signified by centrality and conicity index respectively, and REE was measured by indirect calorimetry. Fat free mass (FFM) were measured by DEXA scan. Thirteen existing prediction equations for estimating REE were compared with MREE among these obese children. Fasting blood for glucose, lipid profile and insulin were obtained. Results: The overall, male and female median MREEs were 7.1 mJ/d (IR 6.2-8.4), 7.3 mJ/d (IR 6.3-9.7) and 6.9 mJ/d (IR 5.6-8.1) respectively. No sex difference was noted in MREE (p=0.203). Most of the equations except Schofield equation underestimated REE of our children. By multiple linear regression, MREE was positively correlated with FFM (p<0.0001), conicity index (p<0.001) and centrality index (p=0.001). A new equation for estimating REE for local use was derived as: REE = (17.4*logFFM) + (l1.4*conicity index) - (2.4*centrality index) - 31.3. The mean difference of new PREE-MREE was -0.011 mJ/d (SD 1.51) with an interclass correlation coefficient of 0.91. Conclusion: None of the existing prediction equations were accurate in their estimation of REE, when applied to obese Chinese children. A new prediction equation has been derived for local use.

The WHO health promoting school (HPS) approach covers key areas including school-based programmes improving students' psychological health, but there have been few studies evaluating the resilience performance of these schools. This study compared the resilience scores between schools within the healthy school award (HSA) scheme (HPS group) and those not (non-HPS group). We conducted a cross-sectional survey of grade- one students (aged, 12), all teachers and parents of mainstream secondary, schools recruited, by .stratified random sampling in one large Territory of Hong Kong using, validated resilience questionnaires during November-December 2005. Four non-HPS and four HPS secondary' schools were recruited, respectively, involving 1408 students, 891 parents and 91 teachers, with similar baseline characteristics. The HPS students were found to have better scores than non-HPS students (average age 12.4 year-old in both groups) in all dimensions with significantly higher scores in 'Peer Support' (p = 0.013), 'Making a Difference' (p = 0.011), 'About Me' (p = 0.027) and 'Generally Happy' (p = 0.011). There was no difference in the scores between non-HPS and HPS parents. The HPS teachers reported significantly higher scores in 'Health Policies' (p = 0.023), 'Social Environment' (p = 0.049), 'School Community Relations' (p = 0.048), 'Personal Skills Building' (p = 0.008) and 'Partnership & Health Services' (p = 0.047). The secondary HPS students and teachers reported significantly higher resilience scores than those of non- HPS. This study shows that the HSA scheme under WHO has the potential to exert positive changes in students and teachers and the concept of HPS is effective in building resilience among major school stakeholders.
