Oscillation of Systems of Parabolic Differential Equations with Deviating Arguments

To study a class of boundary value problems of parabolic differential equations with deviating arguments, averaging technique, Green’s formula and symbol function sign(·) are used. The multi dimensional problem was reduced to a one dimensional oscillation problem for ordinary differential equations or inequalities. Two oscillatory criteria of solutions for systems of parabolic differential equations with deviating arguments are obtained.

FLIP AND N-S BIFURCATION BEHAVIOR OF A PREDATOR-PREY MODEL WITH PIECEWISE CONSTANT ARGUMENTS AND TIME DELAY

In this paper, the stability and bifurcation behaviors of a predator-prey model with the piecewise constant arguments and time delay are investigated. Technical approach is fully based on Jury criterion and bifurcation theory. The interesting point is that the model will produce two different branches by limiting branch parameters of different intervals. Besides, image simulation is also given.

ASYMPTOTIC EQUIVALENCE OF ALTERNATELY ADVANCED AND DELAYED DIFFERENTIAL SYSTEMS WITH PIECEWISE CONSTANT GENERALIZED ARGUMENTS

In this paper, we investigate the existence, uniqueness and the asymptotic equiv- alence of a linear system and a perturbed system of differential equations with piecewise alternately advanced and retarded argument of generalized type （DEPCAG）. This is based in the study of an equivalent integral equation with Cauchy and Green matrices type and in a solution of a DEPCAG integral inequality of Gronwall type. Several examples are also given to show the feasibility of results.

New Criteria for Oscillation of Vector Parabolic Equations with Continuous Distribution Arguments

The oscillations of a class of vector parabolic partial differential equations with continuous distribution arguments are studied.By employing the concept of H-oscillation and the method of reducing dimension with inner product,the multi-dimensional oscillation problems are changed into the problems of which one-dimensional functional differential inequalities have not eventually positive solution.Some new sufficient conditions for the H-oscillation of all solutions of the equations are obtained under Dirichlet boundary condition,where H is a unit vector of RM.

Generalized Central Factorial Numbers with Odd Arguments

Furthermore, the distributions of the signless r-central factorial numbers are derived. In addition, connections between these numbers and the Legendre-Stirling numbers are given.

Analytical Approach to Differential Equations with Piecewise Continuous Arguments via Modified Piecewise Variational Iteration Method

In the present article, we apply the modified piecewise variational iteration method to obtain the approximate analytical solutions of the differential equations with piecewise continuous arguments. This technique provides a sequence of functions which converges to the exact solution of the problem. Moreover, this method reduces the volume of calculations because it does not need discretization of the variables, linearization or small perturbations. The results seem to show that the method is very reliable and convenient for solving such equations.

Political Reasoning and the Typology of Arguments in the Context of Political Philosophy

The main purpose of this article is to present the initial phase of the project in the field of argumentation theory and political philosophy. Project concerns studies of different types of rationality in the context of the argumentation. Background consideration is the problem of incommensurability and incompatibility types of rationality in political and ideological disputes. The first step is the establishment of a category of argumentative potential as a criterion for the typology of argument, which will build a map of argumentation, which will provide a starting point for a discussion. Apart from demonstrating the disproportion of discourses, the conclusion of the argument is to prove the local character of rationality.

A two-phase system call arguments attribute analyzing method

To detect more attacks aiming at key security data in program behavior-based anomaly detection,the data flow properties were formulated as unary and binary relations on system call arguments.A new method named two-phrase analysis(2PA)is designed to analyze the efficient relation dependency,and its description as well as advantages are discussed.During the phase of static analysis,a dependency graph was constructed according to the program's data dependency graph,which was used in the phase of dynamic learning to learn specified binary relations.The constructed dependency graph only stores the information of related arguments and events,thus improves the efficiency of the learning algorithm and reduces the size of learned relation dependencies.Performance evaluations show that the new method is more efficient than existing methods.

Locke’s Tolerance Theory and the Workmanship Argument

John Locke’s tolerance theory involves the core issue of the relationship between reason and belief in the philosophy of religion.However,there is always controversy over whether the scope of adaptation of this theory is within a religion,between religions,or in a broader field.Considering that the overall moral approach of Locke’s philosophy requires the workmanship argument as a defense,and examining it from this point of view,it can be found that Locke’s efforts to transcend Creationism with this argument have resulted in a successful breakthrough,which makes tolerance not only a religion topic,but also a social principle.

Human Rights-based Argumentation in Climate Change Lawsuits

Climate change lawsuits represented by strategic litigation have become a new force to promote global climate governance. Among them, using the norms and theories of human rights law to present litigation claims, conduct legal reasoning, and form human rights-based argumentation has been one of the most successful strategies for climate change lawsuits. The Paris Agreement marked a major watershed for human rights-based argumentation in climate change lawsuits: Before the signing of the Agreement, human rights-based argumentation in climate change lawsuits remained in its trial stage;since the signing of the Paris Agreement, as a litigation strategy, it has become more flexible and diversified, as its relationship with climate governance is becoming increasingly complicated. The uncertainty of climate legal obligation and the process of legalization of climate targets have fostered new dimensions for human rights-based argumentation: Shifting from an accountability logic to a litigation strategy, from international law to domestic law, from holding governments accountable to holding enterprises accountable. There are micro, medium, and macro paths to clarify the human rights-based argumentation, all leading to truly integrating human rights perspectives and ideas into a nation’s specific process of climate governance and valuing and leveraging the value of human rights-based argumentation as a tool, so as to achieve the goal of climate governance.

语言是通过“续”学会的,语言学习的高效率也可以通过“续”实现。学习者如果能提高以续促学的能力,基于续论的外语教学效果就会更加明显。那么,以续促学的能力包含哪些要素?二语学习者以续促学能力的研究理据是什么?在外语教学中,应当如何培养学习者以续促学的能力?为回答这些问题,推动基于续论的外语教学理论和实践的创新,本文首次提出续能的概念,并分析其基本特征和构成要素,梳理当前以续促学能力研究的认知和实证理据,讨论续能研究的价值及续能培养的途径。

气候司法本土化的三重逻辑:规范、价值和功能

在全球气候治理司法化转型的背景下,中国司法系统在应对气候变化中呈现出全面积极的态度。气候司法作为环境司法专门化的新领域,亟须形成体系性的本土化方案。气候司法本土化的核心要义在于彰显主体性,需要将气候司法的概念体系、功能定位、审判机制、裁判体系与规则等置于中国法治现代化特定背景和社会结构条件之中予以把握,其内在逻辑是涵括规范体系、价值序列和功能定位的动态体系。当前,中国气候司法规范体系中的多层次立法呈现间接、倡导属性,且多元化司法规范创制不足,体系化任务尚未完成,继而诱导出气候司法规范的周延性困境和融贯性难题。在此情形下,气候司法所保护法益的识别和核心价值尚未被清晰地析出,且科学上的不确定性、政策权衡、经济诱因等诸多外部因素限制着对气候变化案件的价值判断。这些都深刻地影响气候司法作为公益型司法与治理型司法的双重功能定位和发展方向。为此,气候司法本土化的方式与进路需要基于规范、价值和功能三重逻辑及其呈现的问题或要求展开。首先,强化多重规范秩序的塑造,从公私法协同出发推动气候变化立法体系化,通过强化次级气候司法规范凝聚共识,借助多元法律解释方法提升气候司法规范体系的融通性。其次,以利益为核心建构法律论证的权威,通过涉碳利益的衡量强化裁判的实质理由,通过气候环境利益的多维保护强化裁判的开放性,通过外在因素与法律因素的平衡强化裁判的权威理由。最后,精准塑造气候司法的双重功能,以风险预防原则构建预防性公益型气候司法,以政策的司法化构建服务于“双碳”目标的治理型气候司法。

中小学科学教学中的“伪论证”:表现、症结与破解之道

将科学论证引入课堂教学的目的在于让学生体验类似科学家经历的论证过程,并在此过程中理解科学概念和科学本质,实现科学思维与实践能力的发展。但在实际教学中,“重要素轻知识”“重结论轻过程”“重传授轻协商”的“伪论证”现象层出不穷,科学论证面临认知性、认识性和社会性多重特征的缺位。科学论证的概念分歧与理性失调,评价标准对实践的裹挟以及教师教学惯习的束缚,是“伪论证”现象频繁出现的主要原因。为推动科学论证回归本真,迫切需要从科学实践的视域理解论证的意义,构建科学论证概念框架,创设真实的科学论证环境,同时寻求教师“在行动中反思”的可行路径。

论因明的知识谱系

如果把因明仅仅定义为关于三支论式及其规则之学,重读古典,走进文本,则可以从文本里衍生出因明的知识谱系:从因明的发展演进来看,实现了印度因明到中国化因明的转换;从因明理论来看,三支论式是五支论式的完善,有与亚里士多德三段论不同的概念群;从研究范围来看,涵摄因明理论与应用。因明知识谱系的分析表明,与有效性推理不同,因明有着自己的一套概念体系和应用范围。从产生之初,逻辑就是思想的论证工具。研究逻辑史、写作逻辑史理应从思想论证视角进入,从逻辑理论与应用两个方面发现并总结不同逻辑的各自特征,这是文明互鉴的基础。

基于任务转化的事件抽取通用框架

论元分散、多重事件和论元重叠是事件抽取长期面临的挑战,许多任务还存在触发词或位置标注缺失的情况。对此,提出一种基于任务转化的事件抽取通用框架,包括任务转化、关系抽取和事件预测3个模块。有触发词和无触发词的标注事件分别被转化为不同形式的关系三元组;这些三元组将与原始文本一起作为关系抽取模型的训练数据;事件预测时先从输入文本中抽取三元组,再将它们还原为目标事件。对于训练语料中位置标注缺失的情况,设计了基于最短距离的论元定位算法。该框架在ChFinAnn数据集上取得81.6%的平均F1值,在DuEE-Fin数据集上的F1值为72.04%(在线提交结果),均达到目前的SOTA水平。实验结果表明,该框架不仅可以显著提高事件抽取效果,而且具有广泛的适应能力。
