义务教育资源均衡视角下的学区制改革

学区制是义务教育均衡发展体制和机制创新的实践模式之一,文章从资源均衡的角度对学区制的核心目标进行规定,同时归纳总结了我国目前试行学区制改革的地区的主要内容及改革中的主要薄弱环节,最后从义务教育优质资源的合理化配置、建立新型的学区关系、对优质教育资源进行开发和挖掘、实现优质义务教育的资源共享等四方面探索了学区制改革的路径选择。

Phylogenetic Relationship of an Extremely Endangered Species, Pinus squamata (Pinaceae) Inferred from Four Sequences of the Chloroplast Genome and ITS of the Nuclear Ribosomal DNA

Pinus squamata X. W. Li, a recently-described species of the Pinaceae, is an extremely endangered pine with only 32 individuals in the wild. This species was thought to be intermediate between P. bungeana Zuec. ex Endl. of subgen. Strobus and P. yunnanensis Franch. of subgen. Pinus by the original author. We made an effort to address the question of the phylogenetic relationship of this peculiar and important species in the context of the major groups of the genus Pinus by using sequences of the rbcL, matK,genes, rpl20-rps18 spacer, trnV intron of the chloroplast genome and the nuclear ribosomal ITS region. The results of the separated analysis and the combined analysis of the four cpDNA sequences and ITS sequence indicated that P. squamata was a stable member of subsect. Gerardianae and P. gerardiana Wall. was the closest species of P. squamata phylogenetically. As a result, the causes of the distribution pattern of subsect. Gerardianae were also discussed.

PREVIOUS CONVECTION ANOMALY IN AUTUMN AND WINTER ASSOCIATED WITH THE GENERAL CIRCULATION OVER EAST ASIA IN WINTER AND SPRING AND APRIL PRECIPITATION IN SHANDONG

Using OLR and 850 hPa and 200 hPa wind fields data (1979 - 2006), this paper diagnoses the characteristics of convection over the tropical area in preceding autumns and winters in association with April precipitation anomalies in Shandong province. It is found that preceding convection anomalies over the Western Pacific Warm Pool in December have close relationships with the April precipitation in Shandong. Further analysis of the relationship with the general circulation over the East Asia shows that the convection anomaly over the Western Pacific Warm Pool has close relationships with the Main East Asian Trough, the Hadley cell over East Asia and the Walker cell. The characteristics of East Asian atmospheric circulation anomalies accompanied with stronger (weaker) convection are consistent with those of less (more) April precipitation anomalies in Shandong. Therefore, the convection anomaly over the tropics in December may be an important indicator for April precipitation in Shandong.

The Education of Students of Pedagogy With the Aim of Fostering Multiculturalism in a Community

The paper starts from the theoretical model of multiculturalism as a possibility for an individual to develop their own identity, to accept and respect the identity of other members of a community. The aim of this research is to determine how the students of pedagogy define the concept of multiculturalism and in how far they consider it to be current in contemporary social relationships. The survey was carried out using the descriptive method and the analysis of contents. It examined the attitudes of students who are preparing themselves for advisory work with children in elementary school and high school. The results of the research confirm that the pedagogy students define the concept of multiculturalism clearly. They recognize the need for upbringing that fosters multiculturalism in modern education, in order to gain extensive knowledge and use it in a particular situation.

Thermodynamics of DBI Black Holes in Anti-de Sitter Spacetime

Through the gauge field theory, we obtain the solution of the DBI-AdS black hole, In the meantime, according to the relations between the action and the grand partition function, we obtain the grand partition function in the DBI-AdS black hole. The temperature and the potential of the DBI-AdS black hole are gained from differential of the grand partition function. With the thermodynamic relations, other thermodynamics are also obtained. The solution and the thermodynamics of the DBI-AdS black hole are turned out that they can reduce to the case of a charged black hole in four-dimensional spacetimes.

Conversing in Spanish at a Seniors Center： A Brief Experience of Community-Based and Foreign-Language Learning

This pilot study explored the linguistic gains of intermediate level Spanish learners who completed community-based learning at a Spanish-speaking seniors center. Leamers had the opportunity, rare in foreign-language instruction, to discuss topics from their textbook in authentic native/non-native dyads. The interactions also allowed the seniors to fulfill an identified community needed by socializing in Spanish. Analyses of a post-service survey revealed that learners assessed the experience positively, because they spoke Spanish creatively. Seniors were described as cooperative and fun interlocutors, suggesting that age difference minimally affected the interactions. Direct observation revealed that learners managed to produce L2 Spanish output in connected speech for an extended period of time. Likewise, the seniors enjoyed a moment of socialization and first language use while sharing their views on the topics of discussion with the young visitors. Seniors＇ active participation likely encouraged learners to cope with sudden switches of topics that required negotiating for meaning and pushing the still limited interlanguages. A new service leaming study proposes to investigate the use of native/non-native dyads in Spanish in fulfilling a dual function： socialization and first language maintenance for the seniors at the center and language learning for the students.
