Encrypted objects and decryption processes: problem-solving with functions in a learning environment based on cryptography

This paper introduces an applied problem-solving task, set in the context of cryptography and embedded in a network of computer-based tools. This designed learning environment engaged students in a series of collaborative problem-solving activities intended to introduce the topic of functions through a set of linked representations. In a classroom-based study, students were asked to imagine themselves as cryptanalysts, and to collaborate with the other members of their small group on a series of increasingly difficult problem-solving tasks over several sessions. These tasks involved decrypting text messages that had been encrypted using polynomial functions as substitution ciphers. Drawing on the distinction between viewing functions as processes and as objects, the paper presents a detailed analysis of two groups’ developing fluency with regard to these tasks, and of the aspects of the function concept underlying their problem-solving approaches. Results of this study indicated that different levels of expertise with regard to the task environment reflected and required different aspects of functions, and thus represented distinct opportunities to engage those different aspects of the function concept.     

Linear differential equation with constant coefficients solved by matrix formulation

By the formulation of matrix function, a system of linear differential equations with constant coefficients can be uniquely solved. The desired solution is simply expressed as the matrix product of two factors: (1) a variable vector, uniquely derived from the given system, can be set aside after it is found; and (2) a constant matrix, directly related to the initial conditions, is computed numerically. The effort of re-computation is very minimal upon the initial conditions changed. For the classical Laplace transformation, the solution of the differential equation must be recalculated from the very beginning whenever the initial conditions are altered.A typical numerical example is provided in detail to show the merit of the approaches presented.     

金融衍生产品与风险管理

商业银行可以借助金融衍生产品的经济功能更好地实现经营目的，其主要经济功能包括：转移风险；降低交易成本；发挥财务杠杆作用，提高资产流动性；调整资产组合，实现特定的资产负债结构，不过，转移风险并不等于消灭风险，金融衍生产品交易中同样存在着很大的风险，如果不能正确运用，将引发巨额损失，从而又会限制金融衍生产品的发展。     

基于主体功能区的土地利用分区研究——以内蒙古自治区为例

划分土地利用分区对科学制定土地利用方向、合理确定土地利用结构、提高土地利用集约化程度、促进区域协调发展具有重要意义。本文在总结前人开展的内蒙古自治区土地利用分区的基础上,充分考虑内蒙古自治区主体功能区规划确定的主体功能区对土地利用分区划分的影响,土地利用分区应有利于促进主体功能区形成的前提下,提出基于主体功能区的自治区土地利用分区构想,将自治区土地利用划分形成耕地与基本农田集中区、城镇村发展区、工矿建设区和生态安全保护与建设区4个土地利用功能区。
