Equilibrium in Classical Confucian “Economy”  [PDF]
Shirley Chan
Open Journal of Philosophy (OJPP) , 2012, DOI: 10.4236/ojpp.2012.22015
Abstract: In a modern economy, “equilibrium” means that supply and demand is equal. It is at this point that the allocation of goods and services is at its most efficient, this being because the amount of goods and the amount of goods in demand are equally balanced. The market equilibrium therefore is determined by supply and demand. This paper looks at the concept of “equilibrium” in some of the early Confucian texts and its possible implications in economic activities. In the Confucian context equilibrium, or what can be termed as the ultimate equilibrium, is to be understood in a broader sense where balances and harmony at different levels (e.g. individual and society) need to be sought in order to achieve a model of sustainable development. The ultimate equilibrium may provide an alternative approach to social welfare and economic prosperity creating universal harmony and better living for humans. In Confucian ideology, governing for the welfare of the people is not merely a question of increasing personal income and wealth; it requires implementation on a priority basis, taking into consideration the formation of an orderly society based on the enforcement of moral and ethical standards with the existence of a benevolent government which appropriates things according to the principles of harmony and order to achieve what can be termed as the “great equilibrium”—equilibrium that is not simply defined by balanced economic forces as in modern economic theory; but rather is used to suggest an ideal state of harmony in self fulfilment and socio-political order through incentives and by appropriate means.
Language Learner Autonomy and Learning Contract: A Case Study of Language Majors of a University in Hong Kong  [PDF]
Mable Chan
Open Journal of Modern Linguistics (OJML) , 2015, DOI: 10.4236/ojml.2015.52013
Abstract: With the aim of developing first year undergraduate students’ awareness and ability of autonomous learning, they were asked to do self-access work in an academic English proficiency course through drafting a learning contract outlining their learning objectives and submitting learning evidence regularly in the course of the semester. This study examines the content of the learning contract and the English language learning beliefs reflected from the learning objectives formulated, plus questionnaire results, and determines whether university students in Hong Kong are ready for autonomous learning or not. Based on the findings, the study examines whether Hong Kong university students are ready for autonomous learning, and discusses ways to deal with the challenges which might impede implementation of language learner autonomy in Hong Kong.
Teachers’ Cognition about Teaching and Learning of Simple Past Tense: Can Processing Instruction Help?  [PDF]
Mable Chan
Open Journal of Modern Linguistics (OJML) , 2016, DOI: 10.4236/ojml.2016.64033
Abstract: This study examines how teachers perceive the difficulties and strategies of acquiring simple past tense, and the pedagogical implications. Findings show that teachers’ understanding of the nature of the acquisition problem of tense, and their use of teaching approach are instrumental in shaping students’ learning outcomes. What is fortunate is that they understand the need to improve the existing teaching approach which is too form-oriented. Unfortunately, they do not seem to have much knowledge about how to do so. Findings in the literature should not be limited to researchers; there is a pressing need for teachers to understand the nature of the acquisition problem, possible reasons leading to the difficulty, and ways to help students master both the forms and meaning of simple past tense.
Smart Library and Smart Campus  [PDF]
Hubert C. Y. Chan, Linus Chan
Journal of Service Science and Management (JSSM) , 2018, DOI: 10.4236/jssm.2018.116037
Abstract: The consequence of digitalization, Internet proliferation, and technology advancement, our way of teaching and learning has been changing. The role of library has to be converted into a place for discourse, peer collaboration, social learning, and exhibition concourse. Some scholars believed that the future Library is tied to the technological development of Web4.0 which is characterized by the terminology of Convergence, Remixability, Standardization, Participation, Usability, Economy, and Design. This concept has been extended to Campus. Some universities have started to adopt the latest technology to convert their Campus and Library into Smart ones for the interests of students. The findings of this paper support that the latest development of Smart Campus and library aligns with the new trend of education system, and creates positive impact on the competitiveness of a city. The applications in Smart Camus and Library in reality are also revealed.
How Dark Energy Affects the MOND Theory in Clusters  [PDF]
Man Ho Chan
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.329147
Abstract: Modified Newtonian Dynamics (MOND) is one of the successful theories to explain the dark matter problem in galaxies. However, the data from clusters and the cosmic microwave background (CMB) indicate some dark matter should exist in larger scales. In addition, recent dynamical studies of clusters show that the effect of dark energy should not be ignored in cluster scale. In this article, I will demonstrate how dark energy affects the cluster mass calculation by using MOND. Also, I will show that the calculated cluster mass is consistent with the total matter to baryonic matter ratio obtained by the CMB data.
The Discrimination of English Vowels by Cantonese ESL Learners in Hong Kong: A Test of the Perceptual Assimilation Model  [PDF]
Alice Y. W. Chan
Open Journal of Modern Linguistics (OJML) , 2013, DOI: 10.4236/ojml.2013.33025

This article discusses the results of a study which investigated Cantonese ESL learners’ perception of English vowels and their perceived similarity between similar L1 and L2 vowels in an attempt to test the prediction of the Perceptual Assimilation Model (PAM). Forty university English majors participated in three L2 perception tasks, which aimed at discerning their perception of English vowels spoken in different contexts, and one L1 L2 speech perception task, which aimed at discerning their classification of L2 vowels into native vowel categories and their perceived similarity between similar L1 and L2 vowels. It was found that their classifications of English vowels into Cantonese vowels and their perception of the corresponding English vowels did not provide strong support for the prediction of the model. The effects and extent of native language phonological influence are yet to be determined.

Assessment of Drivers of Deforestation and Forest Degradation in Phnom Tbeng Forest Based on Socio-Economic Surveys  [PDF]
Somanta Chan, Nophea Sasaki
Journal of Environmental Protection (JEP) , 2014, DOI: 10.4236/jep.2014.517155
Abstract: Carbon emission reductions through reducing deforestation and forest degradation or REDD+ scheme of the United Nations Framework Convention on Climate Change could not be achieved without understanding the drivers of deforestation and forest degradation. Until recently, only a handful of study has focused on such drivers. Cambodia experienced rapid deforestation and forest degradation despite growing international interests in protecting forests for carbon revenue generation. This paper was designed to assess livelihood of forest-dependent community and drivers of deforestation and forest degradation in Cambodia. Quantitative and qualitative methods were used to collect socio-economic data from 42 households living in Phnom Tbeng forest, where annual deforestation rate was about 2.4% between 2004 and 2009. Our results suggest that local people depend on forests for income generation, subsistence use and social identity. About 90% of the respondents believed that deforestation was resulted from illegal logging, slush and burn agricultural practices, land clearing for large plantation, land encroachment, firewood extraction, charcoal production and forest fire. As the population has increased rapidly and almost 100% of local people depend on fuelwood for cooking, fuelwood collection will continue to cause deforestation and forest degradation unless alternative sources of affordable energy are provided. Appropriate policy interventions should be proposed to reduce the drivers obtained in this study because if drivers cannot be reduced, it is not possible to reduce deforestation and forest degradation, and related carbon emissions.
Internet of Things Business Models  [PDF]
Hubert C. Y. Chan
Journal of Service Science and Management (JSSM) , 2015, DOI: 10.4236/jssm.2015.84056
Abstract: Almost all businesses are aware of the potential gains that the Internet of Things (IoT) has to offer, they are unsure of how to approach it. This article proposes a business model that builds on Holler et al., (2014) [1]. The model consists of three dimensions: “Who, Where, and Why”. “Who” describes collaborating partners, which builds the “Value Network”. “Where” describes sources of value co-creation rooted in the layer model of digitized objects, and “Why” describes how partners benefit from collaborating within the value network. With the intention of addressing “How”, the proposed framework has integrated the IoT strategy category, tactics, and value chain elements. The framework is then validated through the case studies of some successful players who are either the Awardees of the IoT Award 2014 or the ICT Award 2015 of Hong Kong.
Library3.0 for Public Library  [PDF]
Hubert C. Y. Chan
Journal of Service Science and Management (JSSM) , 2015, DOI: 10.4236/jssm.2015.85075
Abstract: The number of visitors to public library has been dropping in most of the developed cities as a result of digitalization and Internet proliferation. The role of public library has to be converted into a place for discourse, peer collaboration, social learning, and particularly inspiration through and learning from people. Social capital can thus be built up and that the process of building social capital can be part of a community development. Base on the principles of Library3.0 and Connectivism which is considered as the learning theory of this digital age, and the study of “Next” public library, this paper supports that Library3.0 implementation can facilitate this conversion with emphasis on the importance of Personalization in the creation of different space/zones for individual. Library3.0 in reality is introduced at the end.
Effects of Surface Charges on the Seawater Desalination Using Functionalized Graphene  [PDF]
Yue Chan, Yong Ren
Journal of Applied Mathematics and Physics (JAMP) , 2016, DOI: 10.4236/jamp.2016.44066

In this paper, we investigate the selection rule for desalinating seawater using functionalized graphene sheet as a semi-permissible membrane. Both the applied mathematical modeling and MD simulations will be used to determine the acceptance conditions for water molecule or sodium ion permeating into the functionalized graphene. Both the Lennard-Jones potential and Coulomb forces are considered by taking into accounts the major molecular and ionic interactions between molecules, ions and functionalized graphene sheet. The continuous approximation will then be used to coarse grain most significant molecular and ionic interactions so that the multi-body problems could be simplified into several two-body problems and the 3D motions are reduced into degenerated 1D motion. Our mathematical model and simulations show that the negatively charged graphene always accepts sodium ions and water; however the permeability of water molecules and sodium ions becomes very sensitive to the presence of positive charges on the graphene.
