略论现代西方哲学对传统二元论的反对

19世纪中叶，西方哲学发生了重大转折，其最主要的表现是现代西方哲学对传统二元哲学的反对，即反对哲学从思维和存在两极对立出发，主张从人和自然统一的人类世界现实出发进行哲学思维。究其原因：1．它同人的生存方式有关；2．这是哲学本质意义的体现；3．哲学思维范式的转化影响哲学基本问题的解决；4．现代社会发展表明，人与自然是有机的统一整体，哲学必须立足于现实。

从引资战略谈我国外贸结构转变

改革开放以来我国外贸进出口额大幅度提高,跃居世界前列,但同时也存在服务贸易落后、加工贸易比重较高等问题.这种现状是由我国经济发展阶段与对外开放政策及国际跨国公司产业转移等因素决定的.要改变这种现状,我们应该采取适合我国国情的引进外资战略,更有效地利用外资来提升我国对外贸易的结构.

Distributed leadership for personalized learning

Abstract

Personalized learning refers to a collection of practices designed to place student interests and needs at the heart of schooling. Schools that implement personalized learning need leaders that support educators and students in redesigning the core practices of teaching and learning in K-12 schools. To answer the question of how leaders support this redesign, we use distributed leadership theory to focus on the macrotasks and microtasks that leaders enact to create the conditions for personalized learning practices. Drawing on a five-year, qualitative study of 11 personalized learning programs in the Midwest, we identify three macrotasks supporting personalized learning: reorganizing learning environments to support student voice and choice, assembling idiosyncratic technology ecosystems to distribute teaching and learning tasks, and redesigning instructional time to prioritize student’s interests, agency, and learning relationships. After we describe a number of microtasks associated with each macrotask, we discuss how a consideration of these kinds of leadership tasks can open the contemporary discussion of personalized learning from a narrow focus on learning technologies to an expansive vision of student-centered school reform.

Boundary control of a linear distributed parameter bioprocess

This paper is concerned with boundary control of a linear distributed parameter bioprocess. Huang's result (Ann. Differential Equations 1(1) (1985) 43) on the spectrum determined growth assumption is applied to prove that the closed-loop system becomes exponentially stable under a certain condition with respect to the feedback gain. Moreover, it is shown that the decay rate of the open-loop system is given by letting the feedback gain tend to zero.
