Based on the generalized dominance-based rough set approach (G-DR- SA), a synthetic security evaluation method is presented. With-the grey MAGDM security evaluation model as its foundation, the extension of technique for order performance by similarity to ideal solution (TOPSIS) integrates the evaluation of each decision-maker (DM) into a group's consensus and obtains the expected evaluation results of information system. Via the quality of sorting (QoS) of G-DRSA, the inherent information hidden in data is uncovered, and the security attribute weight and DMs' weight are rationally obtained. Taking the computer networks in a certain university as objects, the example illustrates that this method can effectively remove the bottleneck of the grey MAGDM model and has practical significance in the synthetic security evaluation.展开更多

These subtypes represent distinct disease entities, both clinically and at the molecular level. Molecular analysis has revealed significant genetic heterogeneity in ovarian cancer, particularly within the high grade serous subtype. As such, this subtype has been the focus of much research effort to date, revealing molecular subgroups at both the genomic and transcriptomic level that have clinical implications.However, stratification of ovarian cancer patients based on the underlying biology of their disease remains in its infancy. Here, we summarize the molecular changes that characterize the five main ovarian cancer subtypes, highlight potential opportunities for targeted therapeutic intervention and outline priorities for future research.展开更多

Tribal societies have beliefs, which are difficult to understand by modem societies. Their reasoning becomes understandable only when considering that their observations are limited to the macrocosm. Modem societies have access to the microcosm with a microscope, where different biological mechanisms for the conception of a child were discovered. Since the tribes' macroscopical observations were different, their conclusions became necessarily different. The inheritance problem can only be solved by genes at the microscopic level, to which tribal societies had no access. With observations limited to the macrocosm, tribes logically invoked invisible child-spirits of ancestors wanting to be reincarnated in children of the same tribe. Besides the different access to observation, the reasoning of both societies is similar and built around the investigation of a final sense. Reasoning progresses after a phase without any quest for sense through three progressive levels: (1) primary sense, (2) corrected sense, and (3) verified sense. In tribal societies, reasoning is interrupted at the primary sense level when it seems consistent with their general beliefs and traditions. This resembles coherentist theories of epistemic justification, in which justification is only a function of coherence between beliefs. Tribal societies realize the input problem of these theories, since they have no access to the microcosm and also illustrate the Gettier problem. Modem societies progress to the higher levels of corrected and verified sense reasoning, even if inconsistent with their prior beliefs. They initially imagined genes as a hypothetic missing link for inheritance, which relies on a start observation concerning the character of ancestors to the target observation, the similarity with the character of children. If the missing link is definitely verified, it shows a chain of justified beliefs between both observations, allowing the initially hypothetic missing link to be retrospectively considered as the real cause. The SOR of modem societies resembles the extemalist version of foundationalism of epistemic justification, in which the necessary non-inferential justification is represented by the target observation.展开更多

Meanwhile, Software Defined Networking(SDN) emerges as a viable solution to facilitate the deployment of new network paradigm without disrupting production traffic by decoupling the control plane from data forwarding plane. In this paper, the essential properties which reflect ICN working principles are summarized, and a framework called SDICN is designed in accordance to the SDN philosophy. The algorithmic frameworks of SDICN which can satisfy the essential properties are designed based on the programmability and virtualization functions of SDN. Based on Open Flow and data center technology, a prototype of SDICN is implemented. By comparing the performance with the CCNx, the SDICN is proved to be feasibility and availability.展开更多

The World Bank Group has developed a rigorous assessment methodology for assessing a country's ability to access and use knowledge to become more competitive in the knowledge economy of the 21st century. The World Bank's annual knowledge economy index is grounded on a four-pillar model: (1) economic incentives and institutional regime; (2) education and skills; (3) information and communication infrastructure; and (4) innovation systems. An argument can be made that the model lacks coverage of some key factors that pertain to intellectual capital and the production and consumption of knowledge. The model's heavy focus on economic incentives and open institutional regimes comes at a societal cost. This paper proposes an alternative knowledge economy index which is grounded in a more holistic and balanced view of a knowledge society. Adopting the perspective of triple bottom line shifts the purpose and design of a knowledge economy from one of aggregation and reporting to action and involvement. The World Bank's scorecard and indexing methodology are adaptable to this new perspective and a new set of indicators.展开更多

The author first talks about the definition of the hidden curriculum from a theoretical perspective and proposes her own working definition. She then elaborates on the reasons and main manifestations of the hidden curriculum from the teachers' and learners' angles respectively with examples taken from language classrooms. Based on some profound reflections, some feasible suggestions on how to minimize the negative impacts of the hidden curriculum are suggested. On the basis of the previous discussion, the author reaches a conclusion: Language teachers should not avoid or ignore the hidden curriculum existing in the language teaching processes; rather, they are expected to face it positively and try their very best to solve the problems it brings. A sound attitude towards the hidden curriculum can help language teachers better understand and implement the formal or official curriculum made by the school or the state.展开更多

This very program that was brought about in Karl Marx's "Capital" has not been sufficiently expressed in classical or contemporary philosophy. The base of this new Marxist philosophical form is not constructed by the terms of matter, movement, and development overall, but by the conception of the general naturally determined universal process of infinite movement from lower to superior forms of matter. We are aware of four of them: physical, chemical, biological, and social matter. Representing the eternal world as the progressive whole, modern materialism makes nature and proper place of each fundamental science understandable and helps to clarify the location and development future trends of the Man in the world.展开更多

The knowledge base is populated with learnt classification rules categorizing documents into topics. Classification provides for the reduction of the dimensio0ality of the document feature space. The semantic model of retrieved web documents is semantically labeled by querying domain ontology and processed with content-based classification method. The model obtained is mapped to the existing knowledge base by implementing inference algorithm. It enables models of the same semantic type to be recognized and integrated into the knowledge base. The approach provides for the domain knowledge integration and assists the extraction and modeling web documents semantics. Implementation results of the proposed approach are presented.展开更多

However, a corpus-based approach to the study of the collocational behavior of the two frequently-used pairs of synonyms (selection and option, ill and sick) reveals significant discrepancies in the use of these two pairs of synonyms by Chinese English learners and native speakers. According to the analysis, the major problems lie in the current ways of vocabulary teaching and learning. This paper aims to highlight the important role of the corpus-based collocational research in English vocabulary teaching and learning. In the end, some suggestions concerning vocabulary teaching and leaming are put forward on the basis of corpus-based research.展开更多

Their learning processes and attitudes toward such innovation in their community were also examined. Thirty juveniles, 13-18 years of age in each Hangdong and Maerim districts, Chiang Mai province were employed in the study. Data collections were made through questionnaires, interview, test, group discussion and brainstorming. Analysis and evaluation were carried out with the applications of sufficient economy philosophy, constructivism theory and Torrance's future problem-solving instructional model. Results showed that the learning innovation of hyper-multimedia presented by the use of animation, video, scene and sound with related action script synchronization was considerably effective. With the application of sufficient economy philosophy, the result indicated that performance efficiency (El/E2) was 92.228/9.83 and the adolescents learning processes and attitudes were very good. These included purchasing of moderate ICT equipments, information screening for self-immunity and creative using of internet and ICT morally and ethically according to the computer laws. This independent learning system was properly designed for the juveniles with the right to retrieve the data or stop using at anytime. By using Torrance's approach and constructivism theory emphasizing on brainstorming techniques, it was noted that learning process was very well adopted by the adolescents with high satisfaction. They had good attitudes toward the extension of sufficient ICT cultural using in their community with emphasis on brotherly relationship. Related organizations should educate their parents to instruct the juveniles to use the internet properly and encourage people to be aware of ICT business in order to protect social and cultural problems encountered in the future.展开更多

It is argued that many traditional statistical analysis methods with rigorous mathematical footing may not be efficient in extracting essential physical information from climate data;rather,adaptive and local analysis methods that agree well with fundamental physical principles are more capable of capturing key information of climate data. To illustrate the improved power of adaptive and local analysis of climate data,we also introduce briefly the empirical mode decomposition and its later developments.展开更多

The hallmark of a profession is the presence of a common body of knowledge and it can be claimed that a theoretical body of knowledge for the "financial planning profession" has always existed, although it has only been in recent times that agreement has been reached on a common understanding of the theoretical basis of the financial planning profession. This common body of knowledge is the basis upon which the Financial Planning Standards Board [FPSB] is attempting to develop a global curriculum as part of the certification process for financial planners. The FPSB has developed a curriculum framework to be applied by its affiliate members to ensure consistency in global education standards. A review of Certified Financial Planner (CFP) certification in Australia, China, India and the United States exposes differences in how this is approached. The Intemational Organization for Standardization [ISO] has also emerged as another forum in which global financial planning education standards have been set. Although the FPSB's global financial planning education standards has a high degree of compatibility with the ISO standard, the ISO standard has largely remained as a shelf reference.展开更多

I...The issue of income distribution in the modern sense emerged with the creation of the capitalist mode of production-a process characterized by income gaps, at first widening, then narrowing, and widening once again. In the classical economic stage featuring dual economy, income distribution was dominated by capital due to scarce capital and cheap labor, which led to widening income gaps. Entering the neoclassical economic stage, income distribution was dominated by the game between capital and labor due to diminishing marginal return to capital and relatively scarce labor, which led to the growing share of labor compensation and narrowing income gaps. Yet since the 1970s, the deepening of financialization of capital has once again magnified the effect of capital-dominated income distribution, which, together with working class polarization, led to another round of widening income gaps. An observation of the long-term evolution of world economic development and income distribution gives us a clearer view on the intrinsic rationale of change in income distribution: The mode of production determines the mode of distribution and functional distribution shares intrinsic consistency with quantitative distribution.展开更多

A model of joint venture performance in Cambodia is proposed and tested. Finally guidelines for successful joint venture performance in Cambodia are proposed. Based on a study of 62 firms and interviews with 19 joint venture mangers and government officers, it was found that the most important factors driving the formation of a joint venture included access to an emerging new market, utilization of abundant and cheap labor, and existence of government incentives. The most serious obstacles to joint venture performance in Cambodia were corruption, lack of physical infrastructure, bureaucracy, and competition from a black market and smuggling. For the results indicate there are significant correlations between performance and trust, control, commitment, and ownership. Suggested guidelines to improve joint venture performance in Cambodia are proposed.展开更多

Aimed at a set of web services with similar functionality and different quality of service (QoS) , a semantic services chain is given and a corresponding constructing algorithm is proposed to construct the data structure. A pre-filtering process is put forward to find whether a composition service before planning exists. It can avoid aborted planning. An optimal planning algorithm is proposed which can choose the most suitable service from a lot of similar candidate services based on semantic service chains and multi-QoS values. The algorithms can improve the correctness and automation performances of automated semantic web services composition. As an example, a concrete composite process is analyzed. Experimental results show the validity of the composite process.展开更多

文摘To support the rapid automatic services composition and fulfill multi-quality of service (multi- QoS) demand, we propose a novel approach to realize services composition automatically by a prefihering process. Aimed at a set of web services with similar functionality and different quality of service (QoS) , a semantic services chain is given and a corresponding constructing algorithm is proposed to construct the data structure. A pre-filtering process is put forward to find whether a composition service before planning exists. It can avoid aborted planning. An optimal planning algorithm is proposed which can choose the most suitable service from a lot of similar candidate services based on semantic service chains and multi-QoS values. The algorithms can improve the correctness and automation performances of automated semantic web services composition. As an example, a concrete composite process is analyzed. Experimental results show the validity of the composite process.
