The Variety of learning styles requires the variety of teaching strategies. The analysis of learners' learning styles is one of the factors on which the design of learning strategies should be based. Matching teaching strategies and mismatching strategies are chosen intentionally according to the teaching contents, the teaching goals, and the learner's learning styles. Matching teaching strategies can reach the best result of teaching and learning. On the contrary, mismatching strategies can remedy the disadvantages caused by learning styles and be helpful for the development of learning styles.展开更多

Moreover, a subtle change in the distribution of LRs with respect to the pelvis has been observed. In general terms, prior to total mesorectal excision the most common LRs were central types (perianastomotic and anterior) while lateral and posterior forms (presa-cral) have become more common since the growth in the use of combined treatments. No differences have been reported in the current pattern of LRs as a function of the type of approach used, that is, neo-adjuvant therapies (short-term or long-course radiotherapy, orchemoradiotherapy versus extended lymphadenectomy, though there is a trend towards posterior or presacral LR in patients in the Western world and lateral LR in Asia. Nevertheless, both may arise from the same mechanism. Moreover, as well as the mode of treatment, the type of LR is related to the height of the initial tumor. Nowadays most LRs are related to the advanced nature of the disease. Involvement of the circumferential radial margin and spillage of residual tumor cells from lymphatic leakage in the pelvic side wall are two plausible mechanisms for the genesis of LR. The patterns of pelvic recurrence itself (pelvic subsites) also have important implications for prognosis and are related to the potential success of salvage curative approach. The re-operability for cure and prognosis are generally better for anastomotic and anterior types than for presacral and lateral recurrences. Overall survival after LR diagnosis is lower with radio or chemoradiotherapy plus optimal surgery approaches, compared to optimal surgery alone.展开更多

Some typical cross-section shapes, such as triangle, square, pentagon, hexagon and circle, axe carefully explored. The simulation results show that with the same cross-sectional area of the regular polygons, tim thermal conductivities decrease with the reduction of the sides of the polygons, and the thermal conductivity of the circular nanowire is larger than those of the other polygonal ones. Phonon gas kinetic theory is used to analyse the phonon transport in nanowires, and the concept of equivalent diameter is proposed to illustrate the characteristic dimension of the none-circulax cross-section.展开更多

In the current study, the data were garnered from 37 students enrolling in LC 4001 from January 8 to May 7, 2013. Based on the questionnaire, the findings revealed that a large number of the English reading learners acknowledged the mounting importance of English as a linguafranca in the region of 84% and 16% at the "most" and "much" levels, respectively. Likewise, around 90% of the participants had a positive attitude toward such pedagogical method, while only 10% disliked it. Concerning the academic reading curriculum for higher English reading competence, students' different language learning backgrounds and personal excitement caused by reading-aloud activities should be taken on board. Any activity introduced into the classroom should be explicitly stated to the students at the beginning of the course. Using any instructional approach without clear explanations or precautions may seriously upset learners partially or even completely obstruct their effective learning展开更多

Market response curves of price and advertising were presented to calculate the reasonable range based on the market forecast results. The interaction effect of price and advertising was considered,and the game theory was applied to a two-stage price and advertising competition which involved the market share model. A marketing decision support system (MDSS) was developed and simulation data was provided to give the solutions. The operation results show that the leading enterprise makes higher price,spends more on advertising,and earns more profit,while the small-scale enterprise has to lower the price,spend less on advertising,and has slightly higher profit rate. The system is shown to be adaptable to a wide variety of realistic situations.展开更多

Redundant or a diverse range of teaching techniques are not meant to use in the process of their learners' acquiring new vocabulary items; instead, the most effective and to the point teaching techniques in terms of each language skill should be employed. Efficiency of language learners in terms of their command of the vocabulary can be assessed through their understanding any reading or listening context and managing to be productive in speaking or writing procedures in language acquisition process. Phonological, morpho-syntactic, or socio-pragmatic positions of new lexical items as well as the learners' learning styles and multiple intelligences should all be taken into consideration by language teachers so that their learners could really reach an efficient level of vocabulary power. This efficiency has been identified as having a language passport in terms of the proficiency level of the learners within the CEFR (Common European Framework of Reference) for Languages by all EU countries in recent years. Foreign language teachers should try very hard to supply their learners with the required qualifications in every language skill so that they can have a linguistic identity both in their own societies and inter-cultural or multi-cultural contexts. Within this framework, foreign language teachers will hopefully make use of any suggested approach presented in this study so as to widen their learners' horizons in language acquisition process.展开更多

The author pays attention to Japanese output of 19th century Japanese idea that grasped Buddhism into the theoretical frames of western philosophy. The attempt of translating Buddhism with terminology taken from European philosophy allowed not only to refresh the general look at Buddhism, but also to bring it closer to western man. By analyzing the western philosophy, we may often come across many aspects closed to Buddhist idea although we must bear in mind the fact that those similarities can often enough create a misrepresentation. The present article as an attempt is to answer the questions: To what degree can we really speak of knowledge of Buddhism being closed in language frames? Is it possible to get to know Buddhism without its practice, based only on the philosophical studies?展开更多

Legislative and regulatory financial-security regimes have in fact multiplied in recent years. The economic crisis is accelerating the transition of the risk society towards the audit society. But the G20 (Group of Twenty) declarations in Washington and London also reveal a managerial utopia: the march towards a society of confidence or harmony that would make controls superfluous. In this context, the article seeks to call upon philosophical, sociological and managerial references to risk, from Foucault to Power by way of Beck, Giddens & Ewald, to shed light on the official declarations of the leaders of the world's main economies. The documentary corpus examined includes all the G20 works published between November 8, 2008 (preparation for the Washington Summit) and April 2, 2009 (conclusions of the London Summit). The political philosophy underlying the G20's works remains fundamentally liberal, even though saving the worldwide market economy involves established security systems as well as self-control and control of others. In the end, the leaders do not decide between reinforcing the existing tools and inventing new systems. The updating of security technologies is meant to serve the preservation of the capitalist managerial utopia. This gives rise to a new variant of Beck's risk-society paradigm, too often confined to environmental threats alone, in three phases: (1) The crisis is a consequence of financial modernity and in particular of the inefficiency of regulation in the face of growing sophistication in techniques; (2) To restore confidence, the states and international institutions want, paradoxically, both to reinforce regulation and promote flexibility; (3) Thereupon, flexi-security controlled by worldwide economic governance characterizes the second financial modernity.展开更多

The results indicated that the peat fraction give a good dating results sequence in the boreholes, compared with the corresponding organic sediment fraction. And the dating results of organic sediment fraction show 161-6 702 years older than corresponding peat fraction, which was caused by marine influence. Then, we suggest an experience formula as y =0.99 x-466.5 by the correlation analysis for correcting the marine influenced organic sediment ages within the conventional ages between 4 000 to 9 000 yrs BP, and more study should be carried out for the AMS ^(14)C dating of the bulk organic sediments.展开更多

What is a scientific proof?. Philosophical investigations of proofs have the long history. Philosophy is exploring physics, mathematics, astronomy, biology, history, and so on. Science demands strict proofs. Science uses the specific methods as the optimum technologies for the achievement of the truth. Strictness of the proof depends on the aim algorithm: the distribution of the functions between parts of the proof. The beginning stage, the middle parts, and the ending stage are the unit of the proof. Philosophy can make the correct model of the scientific proof only! Science and its methodology develop and the growth of knowledge has not the finish. The rational ideals improve continually. Science is looking for the criterion of the demonstrative strictness. The adaptation algorithm of the scientific method is the best technology for the achievement of the truth.展开更多
