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

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

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

To have a clean, safe, and functional environment is not only essential for the purpose of preservation, but also imperative for safeguarding the most fundamental of human rights. Resolution 45/94 of the United Nations (UN) General Assembly also stresses and acknowledges that: “all individuals are entitled to live in an environment adequate for their health and wellbeing” (United Nations Digital Library System, 1991). Environmental and climate justice, which: “emerged in the context of the local environmental struggles of directly oppressed groups”, is a global movement dedicated to ensuring equal protection of people’s human rights (i.e., water, health, life, etc.) in the face of the climate crisis. Moreover, health, environment and human rights are part of the 2030 agenda (in particular, SDG 1, SDG 5, SDG 6, SDG 7, SDG 13, SDG 16, SDG 17). Individually, both environmental and climate justice are rooted in an intersectional outlook, by which they highlight the common threads between communities and the people’s inclusion, irrespective of race, class, or gender, in the pursuit of justice. On the other hand, they recognise and acknowledge the role and consequences of climate change in economic, social, and political dimensions;thus, drawing emphasis on the rights of people under the emerging inequities. In the case of Palestine, the Palestinian community is increasingly becoming vulnerable to these effects and the resulting inequalities of climate change. This vulnerability stems from: 1) The right to life;clean WASH;equitable work opportunities;access to resources;and free movement;are all examples of human rights that the Israeli colonial regime infringes upon;2) Infrastructure is essential for climate adaptation: 61% of the West Bank is ultimately barred from building infrastructure (B’Tselem, 2019) and Gaza Strip has major gaps in infrastructure due to intentional destruction by Israel;3) Palestinian deprivation of the sovereign right to natural resources by Israel;4) Apartheid system in water accessibility: Israeli water usage per person is over three times higher than that of Palestinians (their usage is under the WHO recommended minimum per day) (B’Tselem, 2023);and 5) Violent settler attacks. In 2022 alone, the Applied Research Institute-Jerusalem (ARIJ) recorded 1527 settler attacks that targeted land, properties, livestock, agriculture and even Palestinian civilians. The ongoing neglect of these concerns and the persistent colonization of Palestine by Israel unequivocally and unwaveringly affect the human rights of Palestinians. The power dynamics at play especially hamper the Palestinian ability to exercise and fulfill their inalienable human rights and to tackle the obstacles to justice in their environment. 展开更多

Space is both a product and a producer of social relations.In the spatial domain,gender blindness has long existed,limiting women’s rights of access to and use of space,leading to structural oppression of women’s rights,and giving rise to new gender inequalities.The barrier-free environment construction has the functions of eliminating physical barriers and generating societal norms,and when combined with social changes,can facilitate justice correction across multiple dimensions.However,barrier-free environment construction itself,as a means of justice correction,also suffers from gender blindness.There remains room for improvement in the areas of facility construction,information exchange,and social services within the realm of barrier-free environments.In response to this phenomenon,gender equality offers a new critical perspective.Therefore,integrating a gender perspective into the barrier-free environment construction,focusing on the spatial rights of women,especially groups with multiple vulnerabilities,such as disabled women and elderly women,can contribute to the advancement towards spatial justice. 展开更多

Online criminal litigation transcends the constraints of physical time and space and changes the logic and path of trial hearings for some criminal cases with the help of technology.However,the leapfrog shift from the“physical field”to the“virtual field”has brought great challenges to the effective exercise of the defendant's right to defense.Online criminal justice further highlights the imbalance in the relationship between prosecution and defense in the context of smart justice,and proposes a new topic for protecting the human rights of the prosecuted.The introduction of online criminal litigation in judicial practice is intended to achieve justice in a faster and more convenient way.However,the dissipation of the ritualized remote hearings tends to undermine the effectiveness of the defense and impair the defense's ability to cross-examine evidence,while the technically advantageous public authorities can aggravate the barrier to the defense's meeting and reading the case file.The root cause is that technological power instrumentalism overemphasizes pragmatism and the pursuit of truth under the position of authority,thus diluting humanistic care for the subject of litigation.In order to resolve the problem with the quality and effectiveness of the right to defense in remote hearings,it is necessary to transform online criminal litigation from a“practical technical tool”to a“convenient auxiliary method,”and appropriately weigh the limits of pursuing truth against human rights protection in special scenarios.Meanwhile,it is also feasible to provide technical care for the defense and strengthen its ability to cross-examine evidence.Moreover,a covert communication platform should be furnished for the defender's online meeting to actively strengthen the protection of the defendant's right to defense. 展开更多

A city is a complex giant system,in which landscape is a process,and emphasizes the regulation of social relationships in the process of creating landscape,rather than simply creating a kind of landscape.In response to the slogan of high-quality development of China,communities,as the earliest developed but declining old areas in Chinese cities,are the focus of current urban renovation work.By studying the latest research theories in the process of community renewal,it is concluded that there is a close relationship between“community renewal”and“landscape justice”or“public participation”.Based on this,research related to community renewal and landscape justice were sorted out,and suggestions for future research focus were proposed. 展开更多
