Cognitive frailty in the elderly:a concept analysis

Frailty is a recession of age-related reserves caused by a variety of causes and is becoming the most important clinical syndrome that affects the health of the elderly.In the elderly,frailty and cognitive dysfunction often exist,and some people have proposed cognitive frailty.Cognitive frailty is an elderly syndrome that increases the risk of dementia,in the same time,and can independently predict the adverse health outcomes of the patient and affect the quality of the patient's survival.This paper,under the guidance of Walker and Avant method,provides theoretical basis for early recognition and intervention of cognitive weakness in the elderly.

On Transferring the Beauty of Poetry:With Special Reference to Translations of A Psalm of Life

From the aesthetic point of view,translation of poetry is to reproduce the beauty both in form and content of the original text in the target text.This paper presents an analysis of how the aesthetic features of form and content of the original work are transplanted and to which degree they get retained in the target text,with special reference to two Chinese versions of Henry Wadsworth Longfellow's A Psalm of Life.

The Research of Strategies of the Loss of Fuzzy Beauty in Chinese-English Translation from the Perspective of Translation Aesthetics

Chinese is a language which emphasizes on artistic conception and parataxis. It embodies spirit in forms and gives read- ers enough space to think and abundant fuzzy beauty. Fuzziness is the mainstream. However, English is an logical language with strict grammar rules which embodies form in spirit. Fuzziness is tributary in English. As a result, it is inevitable to lose the fuzzy beauty during the course of translating from Chinese to English due to these two different languages with diverse value function and appreciation of the beauty. A lot of scholars feel pity and helpless. Starting from the perspective of translation beauty, this thesis an- alyzes the phenomenon of the loss of fuzzy beauty. It introduces the definition of the fuzzy beauty and makes a brief introduction of the wide existence of fuzzy beauty, analyzes the courses and reasons of the loss of fuzzy beauty in the course of translating Chinese to English . At last, it puts forward two specific methods to translate fuzzy beauty, trying to recreate the fuzzy beauty to the most de- gree.

Thoughts on the Construction of Beautiful Villages with Poverty Alleviation in the Perspective

Accurate poverty alleviation has become an important task in implementing the rural revitalization strategy.Since the 19th CPC National Congress,Chinese government institutions have been striving to take measures to lift poor rural areas out of poverty.This essay takes Tailai district as the blueprint to start the research on precision poverty alleviation,explores and discusses the construction of beautiful villages,proposes strategies for sustainable development,makes people change concepts to coordinate the relationship between interests and concepts.It also points out the target that using the industry as a guide,using technology to alleviate poverty and make the village vibrant.Therefore,the endogenous power will be derived from the roots,and the agriculture,farmer and rural area will be fed back,in order to provide a reference for the Construction of Beautiful Villages in Heilongjiang.

Rough Control Rule Mining Model Based on Decision Interval Concept Lattice and Its Application

Fusing the structure feature of interval concept lattice and the actual needs of rough control rules,we have constructed the decision interval concept lattice,further more,we also have built a rules mining model of rough control based on decision interval concept lattice,in order to achieve the optimality between rough control mining cost and control efficiency.Firstly,we have preprocessed the collected original data,so that we can transform it into Boolean formal context form,and then we have constructed the decision interval concept lattice in rough control;secondly,we have established the control rules mining algorithm based on decision interval concept lattice.By analyzing and judging redundant rules,we have formed the rough control association rule base in end.Analysis shows that under the premise of improving the reliability of rules,we have achieved the rough control optimization goal between cost and efficiency.Finally,the model of reservoir scheduling has verified its feasibility and efficiency.

决策形式背景基于OE-协调性的属性约简

属性约简作为形式概念分析中非常重要的一个研究分支,在三支概念分析中也同样重要。基于对象导出三支概念格,提出了保持决策形式背景OE-协调性的属性约简理论,丰富了三支概念分析的约简理论。首先,定义了决策形式背景的OE-协调集和OE-约简,并将属性按其特征分为3类。其次,指出OE-约简的本质就是极小OE-协调集,给出了OE-协调集的几个判定定理,通过研究OE-协调集的充要条件,获取OE-约简的判定定理。最后,给出OE-差别矩阵和OE-差别函数的定义,并给出了利用OE-差别矩阵和OE-差别函数计算OE-约简的方法。

属性偏序形式结构的数学形式化

属性偏序形式结构,作为一种基于人类认知原理和粒计算思想的知识发现和知识表示新理论,目前已有广泛的应用,但其理论基础缺乏抽象化数学化,这势必影响该理论的系统发展。针对上述问题,研究了属性偏序形式结构的数学形式化描述问题。首先,基于粒计算的思想提出了知识表示的形式化框架。在此基础上,通过定义对象集合的覆盖和最简覆盖,给出属性偏序形式结构的粒和粒群的概念,进而通过对粒衍生出粒群的充要条件的讨论,给出了属性偏序形式结构中的知识结构,从而完成属性偏序形式结构的数学形式化描述。最后,通过具体实例展示了利用数学形式化描述构造属性偏序形式结构的过程,并揭示了该过程所体现的人类认知规律。

保持决策蕴涵不变的决策背景属性约简

形式概念分析是一种利用概念格进行数据分析的理论,属性约简是概念格约简的主要方式之一。决策蕴涵是形式概念分析在决策情形下的一种知识表示与推理模型。在已有保持决策背景知识信息不变的属性约简研究中,通常以保持概念规则或粒规则来保持决策背景的知识信息。而相比于概念规则与粒规则,决策蕴涵具备更强的知识表示能力。为了进一步缩小数据在属性约简前后对知识信息表示的差异,对保持决策蕴涵不变的属性约简进行了研究。首先,结合决策蕴涵的语义给出了保持决策蕴涵不变的协调集和约简定义,提出了判定协调集和约简的充要条件;接着,通过实例分析了该约简存在的问题,并结合蕴涵理论给出解决方法,从而给出了弱协调集和弱约简的定义;然后,从知识包含的角度分析了弱约简相比于约简的合理性;最后,提出了判定弱协调集和弱约简的充要条件,并结合决策蕴涵规范基给出了能够找到弱约简的方法,丰富了保持知识信息的属性约简研究内容。

三支概念背景下属性粒化效率的度量

三支概念分析是三支决策与形式概念分析结合的产物,该理论相对于形式概念分析最大的进步是可以同时研究形式背景中“共同具有”和“共同不具有”的信息。属性粒化是一种基于粒度树与剪枝将属性分解为子属性,形成新属性集合的理论。而由于同一粒度树上剪枝众多,如何选择剪枝,确定最优的粒化方向以进行进一步运算成为保证属性粒化效率的关键问题。通过理论推导,证明了原三支概念与属性粒化得到的新三支概念存在紧密的内在联系,以此作为度量属性粒化效率的基础。首先,基于属性粒化层次的关系,将属性粒化层次分为存在偏序关系的属性粒化层次和不存在偏序关系的属性粒化层次。进一步,给到细化系数的含义,并分别阐述了细化系数在2种属性粒化层次中的度量作用,从而达到度量不同属性粒化效率的目的。

基于依赖空间的对象导出三支概念格的属性约简

在给定形式背景下,基于依赖空间提出了对象导出三支概念格属性约简的新定义,在此基础上讨论了属性约简方法。首先,借助三支算子定义了对象幂集上的一致关系,引入依赖空间。通过依赖空间生成闭包算子的闭元素,研究了闭元素和对象导出三支概念的外延之间的关系。其次,提出基于依赖空间的对象导出三支概念格属性约简的定义,该定义下的约简集是保持由原属性集确定的一致关系不变的最小属性子集。最后,给出协调集的判定定理,利用可辨识属性矩阵及辨识函数给出对象导出三支概念格的属性约简方法。

一般决策形式背景的属性约简

决策形式背景是形式背景的重要扩展。属性约简是决策形式背景领域研究的热点问题。由现实数据所构建的决策形式背景通常是不一致的,文中面向实际应用,研究一般决策形式背景的广义属性约简方法。定义了一般决策形式背景的广义属性约简,并基于辨识函数给出了计算所有约简的算法。该算法具有良好的通用性,可应用于一致和不一致的决策形式背景。

正犯概念的理论选择与规范建构——兼论对主犯条款的解释

明确各行为人的定罪根据、实现刑罚的个别化是共同犯罪理论的两个基本问题,对二者的回答集中反映在正犯概念的建构方法上。扩张的正犯概念在形式层面与罪刑法定原则之间存在激烈冲突,在规范层面误将自然和自由予以等同对待,在实践层面不当地扩张了处罚范围,因而并不可取。形式的正犯概念的两大基点是纯粹因果的不法体系和“正犯定性、主犯定量”的分析框架,但这两大基点均不牢靠。有必要继续坚守规范的正犯概念,并以规范地充足构成要件作为正犯建构的指导原则,以此诠释“在共同犯罪中起主要作用”这一主犯特征。正犯建构的核心是行为归责。行为归责的原理包括对实行行为的决断和决定性塑造。由此,可以将正犯概念及主犯条款予以类型化,并为有组织犯罪中首要分子的主犯责任提供法理说明。

A Pluralistic Approach to Human Rights in a Community of Shared Future for Mankind

'A community of shared destiny for all mankind' has its own inherent logic, structure and development path, and a pluralistic concept of human rights is a key factor to achieve its four core goals: equality, cooperation, security and inclusiveness. A pluralistic concept of human rights and the ideal of a community of shared future for all mankind overlap on certain values and interests, as well as power and cultural attributes. It means that a pluralistic approach to human rights is indispensable to the establishment of a community of shared future for all mankind. Meanwhile, this new view of human rights embodies mutual respect and support for the inherent inevitability among different countries, shared responsibility, and pursuit of common development.
