Web-based product design review: Implementation perspective

Product design review is one of the typical scenarios of collaborative product development. We developed a web-based prototype framework for supporting the collaborative tele-product design review on the Internet. It provides a suite of tools to establishing and management the new product design review process. This paper discusses the issues related to the development and implementation of web application in prototype implication. The typical 3-tier architecture is explained to show how the CyberReview components work together to achieve the intended functionality. The VRML EAI and Java Applet-Servlet pair technology was included to support the implication.published_or_final_versio

Encouraging the use of urban green space: the mediating role of attitude, perceived usefulness and perceived behavioural control

Prior studies have identified key factors that influence recycling intention. However, these studies rarely pay attention to the interaction of attitude and subjective norm that influences recycling intention. This study applied a conceptual model by extending the Theory of Planned Behavior (TPB) for addressing the gap. The study collected 246 responses through a street survey in Hong Kong. Findings revealed that two interaction terms (i.e., experiential attitude and subjective norm; instrumental attitude and subjective norm) influenced recycling intention. It implies that subjective norm plays a crucial role in motivating recycling behaviors. Moreover, subjective norm could increase the likelihood of recycling for people exhibiting positive experiential attitude, and motivate people who possesses limited knowledge on recycling benefits of practicing recycling behaviors. Policy implications were drawn from the findings. Limitations of the study and future research direction were also discussed

Salient attributes of urban green spaces in high density cities: the case of Hong Kong

This study aimed to elicit users' perceptions of key attributes of urban green spaces (UGS) in Hong Kong, a compact and land-hungry city, and assess their associations with perceptions of the usefulness, quality, and the frequency of visits in a sample of users of these spaces. This study first employed the repertory grid technique to interviews with 21 respondents to elicit users' assessment of key attributes of green spaces. Second, the factors that emerged were used to develop a questionnaire, which was administered telephonically to 263 individuals who were users of these spaces. The responses were then analysed by multiple regression to assess the extent to which the attributes predicted users' attitudes regarding usefulness and quality and users' behaviour regarding frequency of use of the spaces. The results suggested that the four factors of attributes (features, naturalness, accessibility, and variety of facilities) significantly predicted both of the attitudes and the behaviour relevant to UGS in Hong Kong. Accessibility was most important to the frequency of use and features were the most important to attitudes regarding usefulness and quality. The results imply that policymakers and urban planners could more effectively and sustainably utilise limited land resources by considering users' nuanced meanings and perceptions of urban green spaces. Limitations of the study and future research directions are discussed

A review on political factors influencing public support for urban environmental policy

Environmental quality is important to urban residents’ physical, social and psychological well-being. Governments have been formulating and implementing policies to mitigate environmental deterioration in cities. To effectively implement policies and achieve policy goals, gaining sufficient public support is an essential prerequisite; the policies would be in ruins and the government may also suffer from setbacks in other policy areas in the absence of public support. Therefore, to understand what contributes to public support is a crucial task for policymakers. Though current literature on socio-demographic and attitudinal/psychological factors provides fruitful accounts for policy support, a comprehensive examination of political determinants has yet to be established. In response to this, this review paper explores political factors that influence level of policy support based on existing literature. An integrated framework is proposed to explain policy support for urban environmental policy. This paper also discusses the possible directions of future research

Understanding public support for recycling policy: to unveil the political side of influence and implications

Policy support from the public is gaining importance for successful implementation of environmental policy. Yet the underlying factors of policy support for environmental policy have not been comprehensively examined. While considerable number of studies offered explanation of the phenomenon from the perspective of environmental psychology and social psychology, the growing attention to political factors has not been adequately addressed. In light of this, the present study systematically identified political factors and integrated them with psychological attributes to build a conceptual model for investigating level of policy support for recycling policy. A random household telephone survey was conducted in Hong Kong. 504 valid responses were collected for model testing. The results suggested that although psychological attributes, attitude and perceived benefits, are significant in predicting recycling policy support, political factors are stronger predictors, which perceived policy effectiveness, policy fairness, policy preference, and participatory process demonstrated a significant effect on the level of policy support. In addition, the explanatory power of the conceptual model remarkably increased after political factors were added to the model. The model enables us to compare effects of different sources on the level of policy support, in turn, advances our understanding of the phenomenon. In addition to shaping positive attitude towards recycling and enhancing perceived benefits of recycling practices among the public, policy-makers should put more efforts in formulating a fair, responsive recycling policy that demonstrates capability of policy goal attainment. Public involvement during policy formulation stage is also highly encouraged for mobilizing greater public support

Differential public support for waste management policy: the case of Hong Kong

Gaining public support for environmental policy can promote pro-environmental behaviors and facilitate policy implementation. A telephone survey was conducted in Hong Kong to solicit 504 respondents’ level of support for different waste management policies and to investigate the role of key socio-demographic variables in influencing the level of support for these policies. Data was examined by using multivariate analysis of variance (MANOVA). Findings revealed that variance in policy support for different measures differs significantly across gender, age groups, and education level, while household size and political inclination exhibited less association with support for the policies. Respondents also indicated a varying level of support across policy tools, with policies of developing recycling industry and extending Producer Responsibility Scheme received more support, but municipal solid waste charging scheme and publicity and education measure were less welcomed by respondents. Our analysis infers that current waste management framework should be driven toward a more coherent mode in order to secure greater public support and maximize policy effectiveness. Policy implications could be applied to waste management framework development in cities which share similar background with Hong Kong

The moderating effect of subjective norm in predicting intention to use urban green spaces: a study of Hong Kong

People living in urban areas are encouraged to use urban green spaces (UGS) because of the physical, psychological and social benefits offered by the green environment to city dwellers. Prior studies have investigated the physical, socio-psychological and demographic factors in explaining the use of UGS; however, the moderating effect of social influence has rarely been examined. Based on the theory of planned behaviour, a model extending the predictors of behavioural intention was proposed in this study. Data were collected by a telephone survey conducted in Hong Kong. The results revealed that attitude, subjective norm, perceived behavioural control, and usefulness positively influence people’s intention of using urban green areas. It was also proved that the interaction terms of usefulness and subjective norm, and perceived quality and subjective norm, negatively influence behavioural intention. Insightful implications for studying UGS behaviour, suggestions for urban planning and promotion of using urban green spaces are discussed

Clinical efficacy and safety of buyang huanwu decoction for acute ischemic stroke: a systematic review and meta-analysis of 19 randomized controlled trials

Buyang Huanwu Decoction (BHD) is a well-known traditional Chinese herbal prescription for treating stroke-induced disability. The objective of this study was to evaluate the efficacy and safety of BHD for acute ischemic stroke. A systematic literature search was performed in 6 databases until February 2012. Randomized controlled clinical trials (RCTs) that evaluate efficacy and safety of BHD for acute ischemic stroke were included. Nineteen RCTs with 1580 individuals were identified. The studies were generally of low methodological quality. Only one of the trial included death or dependency as a primary outcome measure. Only 4 trials reported adverse events. Meta-analysis showed the clinical effective rate of neurological deficit improvement favoring BHD when compared with western conventional medicines (WCM), P < 0.001. There is significant difference in the neurologic deficit score between the BHD treatment group and the WCM control group, P < 0.001. In Conclusion, BHD appears to improve neurological deficit and seems generally safe in patients with acute ischemic stroke. However, the current evidence is insufficient to support a routine use of BHD for acute ischemic stroke due to the poor methodological quality and lack of adequate safety data of the included studies. Further rigorously designed trials are required.published_or_final_versio

Meta-analysis of scalp acupuncture for acute hypertensive intracerebral hemorrhage

Objectives: Scalp acupuncture (SA) is a commonly used therapeutic approach for primary intracerebral hemorrhage (ICH) in Traditional Chinese Medicine (TCM), but the efficacy and safety of SA therapy are still undetermined. The aim of this study is to systematically evaluate the efficacy and safety of SA therapy for the treatment of acute hypertensive ICH. Methods: Literature reports with randomized controlled clinical trials and controlled clinical trials on SA therapy for acute hypertensive ICH were searched, and the efficacy and safety of SA therapy were evaluated by using the Cochrane systematic review methods. The primary outcome measures were death or dependency at the end of long-term follow-up (at least 3 months) and adverse events. The secondary outcome measure was neurological deficit improvement at the end of the treatment course. Results: Seven (7) independent trials (230 patients) were included in this study. All trials described the methods of randomization in which four trials had adequate concealment of randomization at the level of grade A, but no trial included sham acupuncture as a control group. None of the trials included "death or dependency" as a primary outcome measure. Four (4) trials contained safety assessments and stated that no adverse event was found, whereas the other three trials did not provide the information about adverse events. By using random effects statistical model, it was found that patients with acute hypertensive ICH who received SA therapy had significantly improved neurological deficit scores (Z=4.97, p<0.01). Conclusions: Although SA therapy is widely used to treat acute hypertensive ICH in TCM, the efficacy and safety of SA therapy remain to be further determined. No evidence is available on whether SA therapy can be used to treat acute ICH according to the primary outcome measure. However, SA therapy appears to be able to improve neurological deficit in patients with acute hypertensive ICH. © 2011, Mary Ann Liebert, Inc.published_or_final_versio
