高等教育研究的学科性、跨学科性及非学科性

从学科建制的标准来看,高等教育学作为一门学科正在被高等教育研究努力建构中。当新的研究范式渗透到高等教育领域,高等教育研究又出现明显的跨学科性取向,这种积极响应进而促使高等教育研究的非学科性又重新"精神焕发"。学术论争充满了变化,持一种开放态度无疑比较妥当。

比较教育的学科性、跨学科性及非学科性

奥利维拉(Oliveira)对在教育科学领域内进行的研究的各个组成部分进行了分类,并对比较教育的地位的这一概念进行了基本的梳理。本文在对奥利维拉著作进行评论后指出:比较教育是一种跨学科领域的研究,这种研究欢迎各种类型的输入信息。然而,人们也注意到比较教育中的有些研究没有很好的界定,且缺乏研究核心。本文关注比较教育从构成它的各个主要学科中多大程度地获益,并意识到比较教育领域中的研究以各种方式为其他研究领域的学者提供了各种思想观点。

跨学科性与视觉文化

跨学科研究有三种基本类型：自上而下型的总体性研究、自下而上型的经验性研究和自里向外型的非学科研究。视觉文化研究属于第三种类型,旨在以视觉性和视觉图像为研究焦点,打破学科界限,进行解构性的整合研究。

Investigation on nonlinear rolling dynamics of amphibious vehicle under wind and wave load

Nonlinear amphibious vehicle rolling under regular waves and wind load is analyzed by a single degree of freedom system.Considering nonlinear damping and restoring moments,a nonlinear rolling dynamical equation of amphibious vehicle is established.The Hamiltonian function of the nonlinear rolling dynamical equation of amphibious vehicle indicate when subjected to joint action of periodic wave excitation and crosswind,the nonlinear rolling system degenerates into being asymmetric.The threshold value of excited moment of wave and wind is analyzed by the Melnikov method.Finally,the nonlinear rolling motion response and phase portrait were simulated by four order Runge-Kutta method at different excited moment parameters.

Extended Hyperbola Function Method and Its Application to Nonlinear Equations

An extended hyperbola function method is proposed to construct exact solitary wave solutions to nonlinear wave equation based upon a coupled Riccati equation. It is shown that more new solitary wave solutions can be found by this new method, which include kink-shaped soliton solutions, bell-shaped soliton solutions and new solitary wave.The new method can be applied to other nonlinear equations in mathematical physics.

Discussion about the Bachelor Thesis of Japanese Major in University

Currently, Bachelor thesis of Japanese major＇s main problems is related to the topics of the irrational, writing both impetuous attitude, which led to poor quality of the article, is worrying. There are many causes of the problem, and you can relax from the writing language requirements, the timing of mentor, and guiding additional academic writing courses in a bid to solve them.

Rationality of escalating commitment in information systems project management： An inter-disciplinary perspective

Escalation of commitment has been linked to losses in information systems （IS） projects. Understanding the nature and the rationality of escalation allows the firm to promote optimal project management practices. This study takes an inter-disciplinary approach and draws on research from economics and management to create a model of irrational escalation and a model of rational escalation. The forces that contribute to irrational escalation include the responsibility of the same manager for both the project selection and project continuation decisions that create proneness to self-justification, the potential for negative framing of decision options due to large sunk costs, the proximity of project completion and the presence of organizational inertia. Identifying these irrational escalation factors helps design appropriate de-escalation techniques. The rational escalation model draws on the real option theory and the bandit process theory to identify conditions when project continuation is justified by the value of information and the value of flexibility that the firm receives from continuing the project.

Irrationality in Scientific Development？

The paper discusses several wide-spread misunderstandings of Kuhn＇s theory of scientific development, most prominently the ascription that he conceives of scientific development as irrational. The core of this ascription is an assessment of incommensurability as implying the lack of any rational possibility of theory comparison. This is supposed to be due to Gestalt switches and a quasi-religious element of conversion in theory change. Accordingly, scientific revolutions cannot be a serious matter for philosophical analysis; they furthermore foreclose any scientific progress. It is shown that such images of Kuhn＇s theory rest on deep misunderstandings that are partly due to Kuhn＇s writing style.

Synergetics as a Positivistic ＂Trick＂ for Philosophy

This paper substantiates the idea that particular science reflects only a certain angle of a complex model of the world. Guidance as to ＂adding＂ particular science data in order to achieve a holistic picture of the world is a philosophical outlook. The meaning of each relatively closed system is revealed only in the context of a more capacious system. According to the author, as the material world itself, its epistemic models as well are built according to the principle of ＂matryoshka dolls.＂ The rational and irrational are discussed in the paper as equal moments of scientific knowledge. Contrary to the importance given to randomness in synergy, the author considers if it is possible to find out the causes of all events. In order to do this, other viewpoints and structure levels should be considered. There is a hidden order in every chaos, and that is revealed only in a certain situation. The main issue is taking into account the counter action of the system with the environment.

Three-dimensional in situ stress determination by anelastic strain recovery and its application at the Wenchuan Earthquake Fault Scientific Drilling Hole-1(WFSD-1)

In situ stress state becomes more and more significant with in-depth research on geodynamics and energy development.However,there has not been an economic and effective method developed to determine deep three-dimensional in situ stress.The Anelastic Strain Recovery(ASR)method is a newly developed technique that can determine three-dimensional in situ stresses.After the 12 May 2008 Ms8.0 Wenchuan earthquake,the ASR method was used for the first time in China's Mainland to measure the in situ stresses in the WFSD scientific boreholes in Sichuan Province,China.In this paper,the basic procedure of the ASR method is introduced in detail and the compliances of ASR for boring cores are investigated.The results show that the maximum principal stress direction was NW64°at a measured depth(MD)of 1173 m(vertical depth 1151 m)in WFSD-1.The ratio of shear mode to the volume mode compliance of ASR was 2.9.And the three principal stresses at 1173 m MD in WFSD-1are 43,28 and 25 MPa.Combined with stress measurement results determined using other in situ measurement methods along the Longmenshan fault zone,the directions of the maximum horizontal principal stress changes from E-W to NEE-SWW to NWW-SEE when moving from NE to SW along the Longmenshan fault zone.This change is in agreement with the stress regime of the Longmenshan fault zone of the Wenchuan Earthquake,which supports a stress regime consisting predominantly of thrusts in the southwest and strike-slip in the northeast.

Drive Control of Spiral Wave and Turbulence by a Target Wave in CGLE

Suppression of spiral wave and turbulence in the complex Cinzburg-Landau equation （CCLE） plays a prominent role in nonlinear science and complex dynamical system. In this paper, the nonlinear behavior of the proposed drive-response system, which consists of two coupled OGLEs, is investigated and controlled by a state error feedback controller with the lattice Boltzmann method. First, spiral wave appropriate parameters of the response system under the no-flux and turbulence are, respectively, generated by selecting boundary and perpendicular gradient initial conditions. Then, based on the random initial condition, the target wave yielded by introducing spatially localized inhomogeneity into the drive system is applied on the above response system. The numerical simulation results show that the spiral wave and turbulence existing in the response system could be successfully eliminated by the target wave in the drive system during a short evolution time. Furthermore, it turns out that the transient time for the drive course is related to the control intensity imposed on the whole media.
