Neuro‐linguistic programming and altered states: encouraging preparation for learning in the classroom for students with special educational needs

In seeking to identify the processes associated with the immediate engagement of learning for students with mild special educational needs, this study examined the responses of an extraction group (n = 7) of 11‐ to 13‐year‐old students who participated in a number of lessons in which the opening episode involved the use of visualisation techniques and language associated with representational systems as identified within neuro‐linguistic programming (NLP). Students endeavoured to alter their negative state to a positive state via this intervention. The study, by Voldis Kudliskis of South Dartmoor Community College, was of a naturalistic research design, and the students' experiences were explored by means of formal interviews, semi‐structured interviews, questionnaires and observations. The implications for altering state through techniques associated with NLP are described and evaluated in terms of student comments. The case is made for the process of altering state as a strategy to empower students to engage with their learning from the outset of the lesson.     

以科学管理导引文化自觉——北京市小学规范化工程的目的与方法

本文对北京市2007年开始的小学规范化建设工程设计进行分析，指出小学规范化建设的目的是提高质量，基线调查、合理规划和增值评价是提高质量的必然要求。基线调查为合理规划、增值评价积累了数据，奠定了基础，增值评价可以为规划的实施情况进行科学评价，三个方法之间是相互联系的。

科研项目选择的0-1目标规划模型

本文论述了科研项目选择问题的重要性，对常用的科研项目选择方法进行了述评。为克服常用方法的缺陷即无力解决具有资源约束的、多目标相互冲突且计量单位不可比的科研项目选择问题，本文提出了基于资源分配的科研项目选择的0—1目标规划模型。最后，对模型进行了测试运行，并对运行结果给出了详细的经济学解释。     

On the intrinsic value of information objects and the infosphere

What is the most general common set ofattributes that characterises something asintrinsically valuableand hence as subject to some moral respect, andwithout which something would rightly beconsidered intrinsically worthless or even positivelyunworthy and therefore rightly to bedisrespected in itself? Thispaper develops and supports the thesis that theminimal condition of possibility of an entity'sleast intrinsic value is to be identified with itsontological status as an information object.All entities, even when interpreted as only clusters ofinformation, still have a minimal moral worthqua information objects and so may deserve to be respected. Thepaper is organised into four main sections.Section 1 models moral action as an information systemusing the object-oriented programmingmethodology (OOP). Section 2 addresses the question of whatrole the several components constituting themoral system can have in an ethical analysis. If theycan play only an instrumental role, thenComputer Ethics (CE) is probably bound to remain at most apractical, field-dependent, applied orprofessional ethics. However, Computer Ethics can give rise to amacroethical approach, namely InformationEthics (IE), if one can show that ethical concern should beextended to include not only human, animal orbiological entities, but also information objects. Thefollowing two sections show how this minimalistlevel of analysis can be achieved. Section 3 provides anaxiological analysis of information objects. Itcriticises the Kantian approach to the concept ofintrinsic value and shows that it can beimproved by using the methodology introduced in the first section.The solution of the Kantian problem prompts thereformulation of the key question concerningthe moral worth of an entity: what is theintrinsic value of x qua an object constituted by itsinherited attributes? In answering thisquestion, it is argued that entitiescan share different observable propertiesdepending on the level of abstraction adopted,and that it is still possible to speak of moral value even at thehighest level of ontological abstractionrepresented by the informational analysis. Section 4 develops aminimalist axiology based on the concept ofinformation object. It further supports IE's position byaddressing five objections that may undermineits acceptability.     

两阶段相结合的广义投影类算法

讨论了非线性不等式约束最优化问题，利用一种新的广义投影技术建立问题的一类算法，该算法的初始点可任意选取，且能自动地将初始化和最优化两阶段统一起来。算法不但无需作任何转轴运算，而且只采用ε－约束集内函数梯度确定广义投影阵，方法结构简单，计算量小，具有普遍意义。     

基于IOWA算子的组合预测方法

有序加权平均(OWA)算子是近年来发展的在多属性决策中用于集结各决策者的偏好信息或方案优选的方法。通过引进诱导有序加权平均(IOWA)算子，提出了以误差平方和为准则新的组合预测模型，给出了IOWA权系数的确定的数学规划方法。该模型能提高组合预测精度，最后的实例分析表明了模型的有效性。
