Based on detailed investigation of the modern sedimentation of the distributive fluvial system of Shule River and the data of unmanned aerial vehicle(UAV)aerial photography and satellite remote sensing,the sedimentary characteristics and differences of distributive fluvial system in arid areas are analyzed.By comparing the changes in slope,river morphology and sedimentary characteristics in different sections from the apex to the toe,the distributive fluvial system of Shule River can be divided into three facies belts:"proximal","middle"and"distal".The proximal belt has the largest slope and strongest hydrodynamic condition,mainly appears as large-scale braided river deposits;the fluvial bars in this belt are mainly composed of gravels,the gravels have good roundness and certain directionality,and are medium-large boulders,with low sand content;the main microfacies in this belt are braided channel and flood plain.The middle belt with slope smaller than the proximal belt,is mainly composed of braided bifurcating river deposits.Due to branching and infiltration,this belt has weaker hydrodynamic conditions,so some of the distributive rivers dry up,appearing as ephemeral rivers.This belt has small lenticular sandbodies,fine to medium gravels,higher sand content,and mainly braided channel,flood plain and aeolian dune microfacies.The distal belt has the smallest slope and flat terrain,where the river begins to transform from braided river to meandering river,the sediment is mainly sand.Due to the influence of slope,this belt has weaker erosion toward source and stronger lateral erosion,and point bars developing around the edge of the active lobes.In this belt,the river is completely meandering,and the main microfacies are braided channel,meandering channel,flood plain,aeolian dune,lake and swamp. 展开更多

A soft group is a parameterized family of subgroups and a fuzzy soft group is a parameterized family of fuzzy subgroups. The concept of fuzzy soft group is the generalization of soft group. Abdulkadir Aygunoglu and Halis Aygun introduced the notion of fuzzy soft groups in 2009[1]. In this paper, the concept of lattice ordered fuzzy soft groups and its duality has been introduced. Then distributive and modular lattice ordered fuzzy soft groups are analysed. The objective of this paper is to study the lattice theory over the collection of fuzzy soft group in a parametric manner. Some pertinent properties have been analysed and hence established duality principle. 展开更多

It is an unarguable fact that the urban-rural dual structure led to two different results. On the one hand,it had been playing a great role in the city development and prosperity,and on the other hand,it had led the slow development of rural economy and the income gap between rural and urban areas. The government makes efforts to promote the process of urbanization to maintain the sustained development of China's economy and economic transformation which are the two needs of the Chinese reality. But in the top-level design of the policy,the government did not give a fair profits distribution to all social groups. On the contrary,the result of urban development is based on the expense of a part of the people's interests in exchange for the interests of another parts of the people,and especially on the government expropriation in the process of urban expansion. Under Land Administration Law of the People's Republic of China,the government monopolized the expropriation right of the rural land,and the rural collectives and farmers as the land owner and constructors respectively have no rights to decide the land use purposes. In fact,they are forced to accept the land compensation,and because of the little bargaining rights,they gain little from the land value increment. Comparatively,the governments became the biggest beneficiary who made use of the land as a source and capital to earn the achievement in their official career and more money required by the urban development. The paper mainly analyzes the current situation of the distribution of the land added value,elaborates the reasons why the government strives for the land interests,and discusses what farmers lose in the government expropriation. Last but not lest,the author reflects on the land reform and gives a proposal on distribution of land added value. 展开更多

Global distributive justice is directly connected to the increased inequality in the world. This inequality, which includes the huge inequality of education opportunities, is usually understood as unjust. There are two main approaches to this problem: cosmopolitan and statist. Looking from the cosmopolitan point of view, this kind of injustice is related predominantly with the socio-economic relationships among the individuals on the planet. Just the opposite is the view of the so-called statists, who claim that a more just world is not a world of persons who are equal among themselves, but rather a world of nation states which are able to achieve a more just society within their borders and, consequently, a more just and egalitarian global society as well. 展开更多

Among the hundred schools of scholars in the pre-Qin period,Confucianism and Mohism were prominent.From the perspective of the emotional motivation of distribution and the fact that individual love is unequal,the Confucianism believes that there is an inevitable natural and reasonable distribution gap.From the perspective of distribution results,Mohism,from the ideal inverse of overall utilitarianism,requires the group to“love without unequal”,and believes that the distribution of selfless“universal love”is reasonable.However,the Confucianism and Mohism views on distributive justice are basically the same in the following five aspects.First,equal distribution of basic means of production and livelihood;second,give priority to the elderly and other vulnerable groups in society;third,oppose extreme individualism;fourth,criticize the polarization of too large distribution gap;fifth,public power should be appropriately opened.Therefore,the view of distributive justice of Confucianism and Mohism is both opposite and unified. 展开更多

It is observed that one of the causes of conflicts and crises in Nigeria society is the inability of the government,religious leaders,politicians and social groups to share equitably benefits,rewards,duties,rights,obligations,and opportunities to the society fairly and excusably to achieve social justice.In the context of the nation’s recent awakening to economic inequalities,it is most helpful here to revisit the meaning and roots of the concept of distributive justice.Distributive justice,requires that the allocation of income,wealth,and power in Nigerian society be evaluated in light of its effects on persons whose basic material needs are unmet.So to address the socio-political,economic,and security challenges of Nigerian society,the unequal distribution of wealth,power,and responsibilities,should be redressed to achieve a peaceful Nigerian society with justice,peace,and security.This work will use qualitative and quantitative methods to undergo the essay.The primary source will be through discussions and interactions with people that have idea on the problems generated by the unequal sharing of the societal power and economic benefits in Nigeria.The secondary source will be the use of the library materials,the Holy Scripture,books,internet,encyclopedia,and journals.Historical,sociological,and analytical approaches will be employed to analyze the data obtained from the sources.The work will dictate the setbacks which Nigeria has suffered by not implementing the principles of distributive justice in the sharing of rewards and responsibilities in Nigerian society.The challenges generated:insecurity,economic depression,political instability that resulted to the creation of different ethnic,religious,and regional militant groups which are strangulating the Nigerian society.To resolve the challenges,the work will address the constitution of the Federal Republic of Nigeria,provisions on the principles of Federal character,Quota System,Fundamental Objectives of State Policy,and the Principles of Fundamental Human Rights as well as considering the implications of the provisions and its effect on the issues to be discussed.Equally,the paper will make recommendations and contribute to how to resolve the irregularities in the sharing of benefits,rewards,and responsibilities in Nigeria society in order to stabilize socio-political,religious,and economic challenges of Nigerian State which will enable us to achieve a peaceful and stable Nigeria with good religion and politics with integrity. 展开更多

Using data from the General Social Survey of Wuhan,China in 2014,this study designs three paths to analyze the direct and indirect relationships between education and perception of distributive justice of income.The first path explores whether education directly affects people’s perception of distributive justice.The second path connects education to socioeconomic status to determine whether higher status results in a higher perception of distributive justice.The last path introduces political trust as a mediating variable to evaluate the relationship between political trust and justice perception.Results show that education is the significant factor that affects people’s political trust and perception of distributive justice. 展开更多

A distribution map of osier weevil (Crytorrynchus lapathi L.) was drown up based on widely collecting information and field survey. The results showed that Osier weevil has a widespread in China, stretching from 33°21' to 51°42' N latitude and 83°00' to 132°58' E longitude, and distributes in forms of big or small patches or sports uncontinously. According to the analysis of meteorological data, the temperature and humidity threshold for osier weevil's distribution were determined by methods of PCA (Principle Component Analysis) and RA(Relativity Analysis): January temperature is -30~ 0℃. Annual temperature -4~13℃, Annual precipitation from 411~ 1,136 min.The areas with January temperature under 0℃, annual temperature above 0℃ and annual precipitation of 400~ 800 mm are the optimum distributing places for osier weevil in China. 展开更多

To achieve the value goal of distributive justice, human society turns to the rational design and organization of social institutions. The construction of social institutions aimed at distributive justice should observe the following principles: equal opportunity, equal distribution of benefits and obligations, rational distribution criteria and procedures, and rectification of injustices. Social institutions established on these principles demonstrate inherent fairness and can ensure that social resources are distributed in an equitable way. For social institutions to ensure distributive justice is of great practical significance because this helps society integrate individuals' singular intentionality of pursuing distributive justice into a collective intentionality that fosters a social perspective on investigating distributive justice, establishes an egalitarian concept of distributive justice, and provides more effective protection for acts promoting distributive justice and stronger sanctions for acts undermining it. This maintains and enhances the interests of both advantaged and disadvantaged groups in distribution. 展开更多

A solution is given for the word problem for free idempotent distributive semirings. Using this solution the lattice L(ID) of subvarieties of the variety ID of idempotent distributive semirings is determined. It turns out that L(ID) is isomorphic to the direct product of a four-element lattice and a lattice which is itself a subdirect product of four copies of the lattice L (B) of all band varieties. Therefore L(ID) is countably infinite and distributive. Every subvariety of ID is finitely based. 展开更多

Distributive fluvial systems(DFS)are widespread in drylands in the northwestern China.Analyzing differences in fluvial morphology in drylands is beneficial for studying ancient rock records and the extraterrestrial surface environment.The remote sensing image,characterized by real-time and possibility of repeated observations,is a vital tool for recording and comparing fluvial systems in drylands.Satellite remote sensing technology is a method of investigating fluvial morphologies.Due to the limited accuracy of satellite imagery,there are few reports on the detailed description of the fluvial system in drylands of NW China.We analyze the pattern of fluvial morphology changes in the Golmud distributive fluvial system(DFS)in the Qaidam Basin,northwestern China,using satellite remote sensing and unmanned aerial vehicles(UAV).Firstly,we use Google Earth real-time image data,historical image data,and radar digital elevation data to extract geomorphological information;then the UAV remote sensing image data were used to interpret fluvial network information;finally,we use the gray-scale differential vector method to describe the fluvial morphologies.Three zones have been identified in the Golmud DFS:the proximal,the medial,and the distal,by comparing the differences in topographic and geomorphic characteristics,fluvial morphologies,and sedimentary characteristics of the Golmud DFS.The proximal slope is higher than the other two zones,and the geomorphic features are mainly gravel gobi.The proximal fluvial morphologies are mainly large braided rivers,and sediments are more gravelly and less sandy.The medial slope is relatively small,and the geomorphic features are mostly oasis plains.The medial fluvial morphologies are mainly meandering rivers associating with braided rivers,and sediments are more sandy and less gravelly.The distal slope is the lowest,and the geomorphic features are mostly oasis plains,lakes,and marsh plains.The distal fluvial morphologies are mainly meandering rivers,and sediments are sandy and muddy.Comparison of the DFS from proximal to medial to distal in Golmud confirmed the potential of remote sensing image technology in identifying the fluvial morphologies and sedimentary facies distribution in dryland. 展开更多

Desert is the core concept of justice, and social desert is the core concept of distributive justice. Distributive justice involves not only the self-ownership of each person, but also the public resources people share and the social fights and economic interests they acquire from the state and society. Everyone has total self-ownership, which forms the basis of many of the rights they enjoy, but this is not the basis of their social desert. Social desert refers to the public value and shared resources that each person can acquire from society. Its basis is people's status as members of a community, a status determined by their position in the political, social and economic structure. Social justice means that everyone gets their just desert in the socioeconomic sphere. The theory of social desert is a theory of resource distribution concerned with social justice in the distribution and allocation of basic social resources. It advocates not only the protection of self-ownership and careful treatment of self-ownership transactions, modifications, and compensation, but also equal enjoyment of basic social resources. Announcing a return to the starting point of social justice, it provides a feasible path to easing social contradictions. 展开更多
