The social security problems of peasants in urban demolition and peasantsh desperate demands are analyzed as follows. For example, the Main problems after the peasants losing their lands cover the substandard of resettlement, which can not maintain the former living standard; the source of income has changed and the relevant security mechanism has not been established; the peasants who have lost their land are in desperate need of more stable jobs and stable income. In view of the current situation, the countermeasures and suggestions for establishing social security mechanism for peasants who have lost their land are put forward. The measures cover establishing the subsistence allowances for land-losing peasants; establishing the guarantee system for aged people; building medical care system; providing employment and training opportunity, trying to increase the channels of employment for farmers and fostering the employment security system for peasants who have lost their land.展开更多

Using data, we analyze the "sideline effect" and inherent contradiction of transformational cities, research the policy needs for social security and its trend in the citizenization process of the peri-urban farmers. On this basis, we construct the social security policy system that can adapt to the accelerated process of urbanization. Finally, we put forth the following recommendations for the social security policy in the citizenization process of the peri-urban farmers: distinguishing different groups' policy needs for social security; attaching importance to people's dynamic policy needs for social security in urbanization; focusing on the adaptability of social security policy transformation in urbanization; attaching importance to the social psychosocial environment of social security policy transformation in urbanization; achieving the trinity of non-farm conversion, urbanization and citizenization in the process of urbanization; strengthening the government's dominant position in the building of social security policy system.展开更多

It considers AI based models that can strengthen or undermine infrastructural functions and organize the networks. In addition, the essay delves into AI’s role in Cyber security software development and the need for AI-resilient strategies that could anticipate and thwart AI-created vulnerabilities. The document also touched on the socioeconomic ramifications of the emergence of AI in Cyber security as well. Looking into AI and security literature, the report outlines benefits including made threat detection precision, extended security ops efficiency, and preventive security tasks. At the same time, it emphasizes the positive side of AI, but it also shows potential limitations such as data bias, lack of interpretability, ethical concerns, and security flaws. The work similarly focuses on the characterized of misuse and sophisticated cyberattacks. The research suggests ways to diminish AI-generating maleficence which comprise ethical AI development, robust safety measures and constant audits and updates. With regard to the AI application in Cyber security, there are both pros and cons in terms of socio-economic issues, for example, job displacement, economic growth and the change in the required workforce skills.展开更多

This paper proposes a feature fusion network model Bert-TextLevelGCN based on BERT pre-training and improved TextGCN. On the one hand, Bert is introduced to obtain the initial vector input of graph neural network containing rich semantic features. On the other hand, the global graph connection window of traditional TextGCN is reduced to the text level, and the message propagation mechanism of global sharing is applied. Finally, the output vector of BERT and TextLevelGCN is fused by interpolation update method, and a more robust mapping of positive and negative sentiment classification of public opinion text of “Tangshan Barbecue Restaurant beating people” is obtained. In the context of the national anti-gang campaign, it is of great significance to accurately and efficiently analyze the emotional characteristics of public opinion in sudden social violence events with bad social impact, which is of great significance to improve the government’s public opinion warning and response ability to public opinion in sudden social security events. .展开更多

However, the issue of sustainability of their contribution to the food security equation is still a dilemma. This study therefore examined the challenges and vulnerabilities associated with women farmers in accessing and controlling land for sustained agriculture in Northern Ghana. The study was mainly qualitative and utilized various participatory dialogue processes including focus group discussions and key informant interviews of selected women farmer groups, individual farmers, opinion leaders and traditional authorities in eight communities across four districts in three regions of Northern Ghana. The data was analysed thematically. Results of the study showed that women are disadvantaged in all the possible means of acquiring land for agricultural production-- inheritance, marriage, rent, shared cropping, outright purchase, and gift. It was evident that women have appreciable levels of access to land, but have low level of control of such lands for sustained food production. Several factors, such as low income, socio-cultural factors, climate change, mining, urbanization, low level of education, and low levels of awareness of property and inheritance rights, associate women's vulnerability to limited land in the study area. The findings of the study imply that any policy geared toward women empowerment in agriculture must not only target their access to land but also consider enhancing their control over agricultural land. The study therefore recommended that in order to increase food production and security in the study regions, there is the need to strengthen women's capacity to defend their land tenure rights and enhance their access and control over land within the context of natural resource management.展开更多

The framework extends the semantic web model and controls the dynamic security of semantic web services, such as trust, logic and reasoning. It includes four layers, that is, a trust entrance layer, a social intelligence layer, a transaction layer, and a TCP/IP security protocols layer. The trust entrance layer deals with trustable features from users. Social intelligence layer is responsible for logical questions for a semantic web. The transaction layer carries out transaction reasoning. And the TCP/IP security protocols layer ensures security communication. These layers can cooperate to build closed-security-ring with different security grades. The integrated security framework provides an integrated security method for semantic web flow so that it is universal for various semantic web technologies.展开更多

Based on the U2IoT model, this paper proposes a cyber-physical-social based security architecture (IPM) to deal with Information, Physical, and Management security perspectives, and presents how the architectural abstractions support U2IoT model. In particular, 1) an information security model is established to describe the mapping relations among U2IoT, security layer, and security requirement, in which social layer and additional intelligence and compatibility properties are infused into IPM;2) physical security referring to the external context and inherent infrastructure are inspired by artificial immune algorithms;3) recommended security strategies are suggested for social management control. The proposed IPM combining the cyber world, physical world and human social provides constructive proposal towards the future IoT security and privacy protection.展开更多

文摘Reasonable income distribution and eradication of rural poverty are vital for building a moderately prosperous society in all respects in China.This paper primarily examines the income distribution and poverty reduction effects of social security spending.Market income and redistribution policies are two determinants of income gaps.Based on CHIP2018 household survey data,we find that inadequate income redistribution policies have contributed to yawning income gaps,and that social security spending is more redistributive than personal income tax and social security contributions.After estimating the redistribution effects of social security spending and itemized incomes,we find that pension payments have contributed the most to household income gaps,and that subsistence protection and rural pension payments help improve income distribution.With respect to the poverty reduction effects of social security spending,we have estimated China’s current poverty incidence and the poverty reduction effects of pension payments,healthcare,and educational allowances with CHIP2018 data,and discover that an increase in social security spending may effectively reduce rural poverty.In building a moderately prosperous society in all respects,China should increase social security spending,focusing on specific target groups,and promote the role of social security spending in regulating income distribution and offering social protection to rural residents.
文摘As the Internet of Things (IoT) is emerging as an attractive paradigm, a typical IoT architecture that U2IoT (Unit IoT and Ubiquitous IoT) model has been presented for the future IoT. Based on the U2IoT model, this paper proposes a cyber-physical-social based security architecture (IPM) to deal with Information, Physical, and Management security perspectives, and presents how the architectural abstractions support U2IoT model. In particular, 1) an information security model is established to describe the mapping relations among U2IoT, security layer, and security requirement, in which social layer and additional intelligence and compatibility properties are infused into IPM;2) physical security referring to the external context and inherent infrastructure are inspired by artificial immune algorithms;3) recommended security strategies are suggested for social management control. The proposed IPM combining the cyber world, physical world and human social provides constructive proposal towards the future IoT security and privacy protection.

文摘Social security has,as one of its primary aims,the provision of financial support to those deemed to be poor or facing the threat of poverty.Based on China's national statistical data covering social insurance,social assistance,and social welfare between the period 1978–2018,this paper evaluates the effect of social security expenditure in reducing income inequality and rural poverty with cointegration analysis.It was found that there is a positive correlation between social security expenditure and the income gap of urban and rural residents in the long run,but the effect is very limited;nearly 99%of the changes of the urban–rural income gap come from its own contributions.Further research also shows that the elasticity of rural poverty incidence to social security expenditure is–0.2255,which indicates social security expenditure helps reduce rural absolute poverty.Based on these findings,the policy implications can be that much social security expenditure and a more equitable social security system should be encouraged.It will become one of the major anti-poverty strategies after 2020 in China when we win the battle against absolute poverty.
文摘In 70 years since the founding of the People’s Republic of China,China has successfully transitioned from a closed economy to an open economy with the watershed year of reform and opening up in 1978 and modernized its social security system accordingly.This paper divides the transition of China’s social security system into seven stages before and after 1978.The traditional social security system was predicated on the dominant public ownership,a highly centralized economy,and“full employment.”It was congruous with the ownership structure,income distribution,and labor systems under the closed economy.The modern social security system is developed to meet the needs of an open economy and promotes economic development by giving play to consumption and investment,facilitating labor flow,and boosting productivity.The modern social security system requires further supply-side structural reforms to promote the high-quality development of the open economy.

文摘From the situations about the incomes and life quality of the urban and rural residents,the thesis briefly introduces the status quo of the urban-rural income gap and explores the impact of the income gap on social economy:firstly,it hampers economic development;secondly,it is detrimental to the social development.Then the thesis analyzes the role of a sound social security in narrowing urban-rural income gap:at first,it broadens the institutional environment of improving the agricultural efficiency;secondly,it eliminates the uncertainties influencing the farmers' income;thirdly,it improves the farmers' capacity to increase income;at last,it enhances the farmers' consciousness of wealth.Next the thesis inquires into the problems existing in the system of rural social security:the first problem is more obviously fragmented system;the second is inadequate security projects and narrower coverage;the third is an obvious lack of equality in urban and rural security;the fourth is even less sound management system;the last is the lagging of legislation.Afterwards the thesis proposes the countermeasures and suggestions to improve the system of rural social security and narrow urban-rural income gap:firstly,to integrate the social security system in rural areas;secondly,to perfect security projects and enhance the security system;thirdly,to integrate the administrative management of social security;at last,to enforce the legal system.
