Reflections on Cultivating Critical Thinking in Foreign Language Courses in the Context of Integrating Ideological and Political Theories in All Courses

The education reform of integrating ideological and political theories in all courses is crucial in fostering virtue through education.In the new era,foreign language courses are increasingly prominent in moral education.Learning a language is not just about mastering its language form but also about critically examining the cultural connotations and thinking patterns embedded within it.Therefore,cultivating students’critical thinking skills should be a key focus in foreign language education.First,this paper examines the importance of fostering students’critical thinking in foreign language courses.Second,considering the characteristics of Chinese college foreign language courses,we propose that if we want to cultivate critical thinking among students through foreign language courses,we need to effect pattern transformations across four aspects:teaching philosophy,teaching content,teaching methodology,and teaching evaluation.These transformations also present requirements for foreign language teachers.They should focus on enhancing their comprehensive literacy,including ideological and political literacy,teaching design skills,and the ability to integrate teaching materials with logical thinking.And China’s Standards of English Language Ability(the CSE)serves as an important reference indicator for implementing these transformations.

为促进安全管理标准化管理模式顺利实施,铁路建设项目安全管理迈向高标准高水平,开展铁路建设项目安全管理标准化评价研究。首先,以标准化管理为理论基础,根据质性研究方法-扎根理论对数据进行编码处理,建立以制度管理标准化、人员配备标准化、物料管理标准化、环境管理标准化、现场作业标准化、过程控制标准化为6个核心范畴和32个主范畴的铁路建设项目安全管理标准化评价指标体系。其次,借助劳伦茨曲线的基尼系数改进CRITIC方法,提出“G1-CRITIC-距离函数判别法”模型,计算属性权重。最后,采用VIKOR算法对案例项目进行实证分析,基于安全管理标准化值U_(R)评估标准化管理水平。结果表明:各案例项目的安全管理标准化水平不同,U_(R)值具有显著差异,P_(1)~P_(5)各项目的U_R值分别为0.047 6、0.148 3、0.451 9、0.971 5、0.648(其中P_(4)属于“高水平”;P_(3)和P_(5)属于“中水平”;P_(1)和P_(2)属于“低水平”)。通过折衷系数扰动下的敏感性分析,综合考虑群体效用和个体妥协,对不同等级的建设项目(P_(1)~P_(5))分别进行讨论,并提出标准化建设的决策建议。研究结果与各案例项目实际安全管理标准化程度相符,为深入推进铁路建设项目标准化管理工作、促进建设项目各项安全管理行为规范运作和管理体系的持续改进提供参考依据。

On Ethical Literary Criticism and Game Theory--An Interview with Professor Nie Zhenzhao

In 2014,Huang Kaihong,a professor at School of Foreign Languages and Cultures,Southwest University of Science and Technology,interviewed the Doctoral advisor Professor Nie Zhenzhao during the period of his academic visiting to Central China Normal University.As early as in 2005,Huang Kaihong conducted an interview with Professor Nie Zhenzhao on the topic of the general introduction of ethical literary criticism.So around 11 years later,the second interview mainly covers not only the ethical literary criticism theory,but the game theory and the relationship between them as well.Professor Nie thinks whether the game theory can be applied to literature research is still under discussion.The theory of ethical literary criticism is a kind of methodology based on science and it can get the attention of literary critics at home and abroad,which is because it fits the practical needs of literary criticism,draws the literary criticism away from only emphasizing criticism genres and the research of criticism terms,and pays attention to the true nature of the literary text in literature research.After consulting Professor Nie Zhenzhao about some related questions from the perspective of game theory.Huang Kaihong gets some significant information concerning literature research and understands the latest core terms and the concrete application method of ethical literary criticism,especially the relationship between the instructing and aesthetic functions of literature.

SOLUTIONS TO DISCRETE MULTIPARAMETER PERIODIC BOUNDARY VALUE PROBLEMS INVOLVING THE p-LAPLACIAN VIA CRITICAL POINT THEORY

In this paper, we consider the existence of three nontrivial solutions for a discrete non-linear multiparameter periodic problem involving the p-Laplacian. By using the similar method for the Dirichlet boundary value problems in [C. Bonanno and P. Candito, Appl. Anal., 88（4） （2009）, pp. 605-616], we construct two new strong maximum principles and obtain that the boundary value problem has three positive solutions for λ and μ in some suitable intervals. The approaches we use are the critical point theory.

On the energy conservation and critical velocities for the propagation of a "steady-shock" wave in a bar made of cellular material

The propagation of shock waves in a cellular bar is systematically studied in the framework of continuum solids by adopting two idealized material models, viz. the dynamic rigid, perfectly plastic, locking （D-R-PP-L） model and the dynamic rigid, linear hardening plastic, locking （D-R-LHP-L） model, both considering the effects of strain-rate on the material properties. The shock wave speed relevant to these two models is derived. Consider the case of a bar made of one of such material with initial length L 0 and initial velocity v i impinging onto a rigid target. The variations of the stress, strain, particle velocity, specific internal energy across the shock wave and the cease distance of shock wave are all determined analytically. In particular the ＂energy conservation condition＂ and the ＂kinematic existence condition＂ as proposed by Tan et al. （2005） is re-examined, showing that the ＂energy conservation condition＂ and the consequent ＂critical velocity＂, i.e. the shock can only be generated and sustained in R-PP-L bars when the impact velocity is above this critical velocity, is incorrect. Instead, with elastic deformation, strain-hardening and strain-rate sensitivity of the cellular materials being considered, it is appropriate to redefine a first and a second critical impact velocity for the existence and propagation of shock waves in cellular solids. Starting from the basic relations for shock wave propagating in D-R-LHP-L cellular materials, a new method for inversely determining the dynamic stress-strain curve for cellular materials is proposed. By using e.g. a combination of Taylor bar and Hopkinson pressure bar impact experimental technique, the dynamic stress-strain curve of aluminum foam could bedetermined. Finally, it is demonstrated that this new formulation of shock theory in this one-dimensional stress state can be generalized to shocks in a one-dimensional strain state, i.e. for the case of plate impact on cellular materials, by simply making proper replacements of the elastic and plastic constants.

Advances in low-field nuclear magnetic resonance(NMR) technologies applied for characterization of pore space inside rocks:a critical review

NMR serves as an important technique for probing rock pore space,such as pore structure characterization,fluid identification,and petrophysical property testing,due to the reusability of cores,convenience in sample processing,and time efficiency in laboratory tests.In practice,NMR signal collection is normally achieved through polarized nuclei relaxation which releases crucial relaxation messages for result interpretation.The impetus of this work is to help engineers and researchers with petroleum background obtain new insights into NMR principals and extend existing methodologies for characterization of unconventional formations.This article first gives a brief description of the development history of relaxation theories and models for porous media.Then,the widely used NMR techniques for characterizing petrophysical properties and pore structures are presented.Meanwhile,limitations and deficiencies of them are summarized.Finally,future work on improving these insufficiencies and approaches of enhancement applicability for NMR technologies are discussed.

Critical emancipatory reflection on a practice-based issue in relation to the working relationship between doctors and nurses in China

Objective: Reflection is viewed as the most significant skill and should be advocated for lifelong learning. In order to grasp the process of reflection and embrace the reflective skill, one of the authors of this paper reflects on a practice-based issue in relation to the communication between doctors and nurses, to gain new understanding and thus improve the authors' clinical practice.Methods: Smyth's framework with four stages is utilized as an ideal framework to guide the author's reflection on the practice-based issue to free the author from her entrenched assumptions and the oppressive forces that limit her practice.Results: The espoused and enacted theory, together with the critical reflection theory, are used to explore the values and beliefs that essentially govern the author's practice and how these are distinct from the author's worldviews. Following this, critical emancipatory reflection is undertaken to explore the dominant power structures within the author's workplace. Furthermore, given the hegemonic and chaotic working context of this issue, hegemony and symbolic interaction theory are applied to unearth the various hidden constraining and oppressive forces. Additionally, socialization theory is utilized to help the author achieve professional identity.Conclusions: Reconstructing the practice-based issue empowers the author to realize that in the future, she should act as a reflective practitioner, creating a daily habit, staying alert to practice, seeing things freshly, finding support systems, improving communication skills, conducting reflective research, and reifying reflective practice. Ultimately, the author will be sufficiently equipped to be able to transform her practice and change its outcomes.

The upper critical field in two-band layered superconductors

The upper critical field of clean MgB2 is investigated using the two-band layered Ginzburg-Landau （GL） theory. The calculated results are fitted to the experimental data of clean MgB2 crystal very well in a broad temperature range. Based on the GL theory for clean superconductors, a phenomenological theory for dirty superconductor is proposed. Selecting appropriate parameters, two-band layered GL theory is successfully applied to the crystal of Mg（B1-xCx）2 and the neutron irradiation samples of MgB2.

WELL-POSEDNESS IN CRITICAL SPACES FOR THE FULL COMPRESSIBLE MHD EQUATIONS

In this paper we prove local well-posedness in critical Besov spaces for the full compressible MHD equations in R^N, N≥ 2, under the assumptions that the initialdensity is bounded away from zero. The proof relies on uniform estimates for a mixed hyperbolic/parabolic linear system with a convection term.

Free vibration and critical speed of moderately thick rotating laminated composite conical shell using generalized differential quadrature method

The generalized differential quadrature method （GDQM） is employed to con- sider the free vibration and critical speed of moderately thick rotating laminated compos- ite conical shells with different boundary conditions developed from the first-order shear deformation theory （FSDT）. The equations of motion are obtained applying Hamilton＇s concept, which contain the influence of the centrifugal force, the Coriolis acceleration, and the preliminary hoop stress. In addition, the axial load is applied to the conical shell as a ratio of the global critical buckling load. The governing partial differential equations are given in the expressions of five components of displacement related to the points ly- ing on the reference surface of the shell. Afterward, the governing differential equations are converted into a group of algebraic equations by using the GDQM. The outcomes are achieved considering the effects of stacking sequences, thickness of the shell, rotating velocities, half-vertex cone angle, and boundary conditions. Furthermore, the outcomes indicate that the rate of the convergence of frequencies is swift, and the numerical tech- nique is superior stable. Three comparisons between the selected outcomes and those of other research are accomplished, and excellent agreement is achieved.

A critical reflection on improving effective team communication

Objective: This paper aims at critically reflecting on the author's personal experience in the context of communication within a nursing team and exploring relevant existing constraints with a view to improving practice and achieving more effective outcomes in team communication.Methods: Critical emancipatory reflection is used to evaluate and interpret the author's practice. Smyth's model serves as a framework to guide critical reflection step by step in this paper. Relevant theoretical perspectives help to make sense of the author's performance in terms of team communication.Results: It is identified via emancipatory reflection that the author endorses the ideas of equality, respect, trust, and collaboration, which were formed and established during the process of professional socialization. However, different constraints, such as sociocultural,historical, political, and personal factors, impede the author from performing more effectively in terms of team communication.Reconstruction provides the author opportunities to take actions to rectify constraints and avoid the reemergence of previous situations in the future.Conclusions: Reflection is an effective way to gather knowledge and develop comprehensive understanding of practice. Alternative actions for effective team communication are recommended, including formulating ground rules for discussion, guiding nurses in the correct way, transforming conflicts within a team, being an active and reflective listener, and motivating nurses to actively create.

Stability Analysis of a Single-Degree-of Freedom Mechanical Model with Distinct Critical Points: I. Bifurcation Theory Approach

The buckling and post-buckling response of a single-degree-of-freedom mechanical model is re-examined in this work, within the context of nonlinear stability and bifurcation theory. This system has been reported in pioneer as well as in more recent literature to exhibit all kinds of distinct critical points. Its response is thoroughly discussed, the effect of all parameters involved is extensively examined, including imperfection sensitivity, and the results obtained lead to the important conclusion that the model is possibly associated with the butterfly singularity, a fact which will be validated by the contents of a companion paper, based on catastrophe theory.

Self-Organized Criticality Theory Model of Thermal Sandpile

A self-organized criticality model of a thermal sandpile is formulated for the first time to simulate the dynamic process with interaction between avalanche events on the fast time scale and diffusive transports on the slow time scale. The main characteristics of the model are that both particle and energy avalanches of sand grains are considered simultaneously. Properties of intermittent transport and improved confinement are analyzed in detail. The results imply that the intermittent phenomenon such as blobs in the low confinement mode as well as edge localized modes in the high confinement mode observed in tokamak experiments are not only determined by the edge plasma physics, but also affected by the core plasma dynamics.

A Corpus-Based Critical Discourse Analysis of Trump and Biden Administrations’China Policies

The theory of proximization is an effective discourse strategy to study the speaker’s ability to achieve his own legitimacy or reinforce the other’s illegitimacy,and its superiority can be maximized by means of quantitative and comparative analysis.In this study,we collected reports on Trump’s and Biden’s policies on China to build two small corpora,with a total of 11,030 words in the Trump corpus and 17,566 words in the Biden corpus.The critical discourse analysis is combined with proximization theory.With the help of BFSU Qualitative Coder 1.2,Antconc 3.5.7,and Log-Likelihood and Chi-Square Calculator 1.0,a critical cognitive score of the relevant discourse was conducted from the perspective of proximization theory.It has been found that:(1)Both Trump and Biden administrations resort to a large number of spatial proximization strategies to build ODCs converging to IDCs with China as the ODC,posing a threat to internal physical IDCs;(2)in the use of temporal proximization strategy,both administrations use primarily modal verbs and various entities to construct ODCs that extend indefinitely into the present and future,emphasizing the urgency and the threat of the effect and reinforcing the legitimacy of their actions;(3)in terms of axiological proximization strategy,the two administrations differ greatly from each other,indicating that there are still discursive biases.

Critical reflection on the role of theater nurses in a multidisciplinary team for perioperative care in China

Objective: The aim of this article is to reflect on the role of theater nurses in a multidisciplinary team, understand the factors that have influenced theater nurses' practice, and improve the authors' clinical practice ultimately.Methods: The author used Smyth's model to guide the process of reflection on the practice issue. Critical reflection, critical emancipatory theory, reflexivity, and critical social theory were used to help the author analyze the factors that have affected theater nurses' practice in the organization.Results: There are gaps between the espoused and enacted theories. A theater nurse's practice is determined by multiple factors, such as political, structural, social, historical, cultural issues, and so on. The hierarchy of the health context could hinder possible changes in theater nurses' practice. To better understand our practice and implement transformation, we should shape a supportive environment,bear in mind the practice motto of "patient-centered" care, and improve our knowledge and reflection skills.Conclusions: Reflection plays a significant role in the advancing of practice among theater nurses and needs to be combined with clinical practice. To provide the best service of care to perioperative patients, a theater nurse should have an insightful understanding of the factors that have influenced her/his behaviors historically, socially, and culturally. By improving their critical reflection skills,practitioners could gain knowledge from experience.

Stability Analysis of a SDOF Mechanical Model with Distinct Critical Points: II. Catastrophe Theory Approach

In a recent publication [1], the fully nonlinear stability analysis of a Single-Degree-of Freedom (SDOF) model with distinct critical points was dealt with on the basis of bifurcation theory, and it was demonstrated that this system is associated with the butterfly singularity. The present work is the companion one, tackling the problem via the Theory of Catastrophes. After Taylor expanding the original potential energy function and introducing Padè approximants of the trigonometric expression involved, the resulting truncated potential is a universal unfolding of the original one and an extended canonical form of the butterfly catastrophe potential energy function. Results in terms of equilibrium paths, bifurcation sets and manifold hyper-surface projections fully validate the whole analysis, being in excellent agreement with the findings obtained via bifurcation theory.

Optimization of Critical Systems for Robustness in a Multistate World

Critical systems are typically complex systems that are required to perform reliably over a wide range of scenarios, or multistate world. Seldom does a single system exist that performs best for all plausible scenarios. A robust solution, one that performs relatively well over a wide range of scenarios, is often the preferred choice for reduced risk at an acceptable cost. The alternative with the maximum expected utility may possess vulnerabilities that could be exploited. The best strategy is likely to be a hybrid solution. The von Neumann-Morgenstern Expected Utility Theory (EUT) would never select such a solution because, given its linear functional form, the expected utility of a hybrid solution cannot be greater than that of every constituent alternative. The continuity axiom and the independence axiom are assessed to be unrealistic for the problem of interest. Several well-known decision models are analyzed and demonstrated to be potentially misleading. The linear disappointment model modifies EUT by adding a term proportional to downside risk;however, it does not provide a mathematical basis for determining preferred hybrid solutions. The paper proposes a portfolio allocation model with stochastic optimization as a flexible and transparent method for defining choice problems and determining hybrid solutions for critical systems with desirable properties such as diversification and robustness.
