Due to the transparency of the wireless channel, users in multiple-key environment are vulnerable to eavesdropping during the process of uploading personal data and re-encryption keys. Besides, there is additional burden of key management arising from multiple keys of users. In addition, profile matching using inner product between vectors cannot effectively filter out users with ulterior motives. To tackle the above challenges, we first improve a homomorphic re-encryption system (HRES) to support a single homomorphic multiplication and arbitrarily many homomorphic additions. The public key negotiated by the clouds is used to encrypt the users’ data, thereby avoiding the issues of key leakage and key management, and the privacy of users’ data is also protected. Furthermore, our scheme utilizes the homomorphic multiplication property of the improved HRES algorithm to compute the cosine result between the normalized vectors as the standard for measuring the users’ proximity. Thus, we can effectively improve the social experience of users.

Cyberstalking has become a new form of crime and deviant behaviour. The authors research the problem of cyberstalking and intimidation via the Internet in details. These concepts are used interchangeably because all forms of stalking are threatening or have the purpose of distressing the victim (victim stress exhaustion). The authors tried to draw attention and show the interconnectcion between the social danger of cyberstalking and the violation of private life boundaries. The consequences of such interference can cause the significant harm to man interests, material harm; threaten the physical and mental health of a person. The authors in this article draw attention to the activities of people who use the Internet to threaten (intimidate) others. The phenomenon of cyberstalking constitutes one of the main aims of the analysis because it includes a rather large area of behavior performance (starting with the expression of threats to the theft of personal data). The main question of this research is simple: what makes an intelligent and law-abiding person in the offline world (outside the Internet), take part in anti-social or criminal activities online? The basic reason is the fact that the combination of technological and social factors encourages people to participate in crime or antisocial acts, such as incitement to violence against other people. The originality of the study is that the authors analyzed the public danger of cyberstalking and the consequences of privacy infringement by the negative impact on a person through the Internet. Authors highlight trends and developments, and give recommendations on how cyberstalking prevention matters can be improved.

Health is the basic right for everybody, therefore every citizen is entitled to get the health care. In enforcing the regulation for Jaringan Kesehatan Nasional (National Health Supports), it is heavily influenced by the foreign interests. Economically, this program does not reduce the people’s burdens, on the contrary, it will increase them. This means the health supports in which should place the government as the guarantor of the public health, but the people themselves that should pay for the health care. In the realization of the health support the are elements against the Syariah principles. Indonesian Muslim Religious Leaders (MUI) only say that the BPJS Kesehatan (Sosial Support Institution for Health) does not conform with the syariah. The society is asked to register and continue the participation in the program of Social Supports Institution for Health. The best solution is to enforce the mechanism which is in accordance with the syariah principles. The establishment of BPJS based on syariah has to be carried out in cooperation from the elements of Social Supports Institution (BPJS), Indonesian Muslim Religious (MUI), Financial Institution Authorities, National Social Supports Council, Ministry of Health, and Ministry of Finance. Accordingly, the Social Supports Institution for Helath (BPJS Kesehatan) based on syariah principles could be obtained and could became the solution of the polemics in the society.

The article examines the contribution of the representatives of the Samarin family to the development of the Parish issue in the Russian Empire in the late 19th and early 20th centuries. The issue of expanding the rights of the laity in the sphere of parish self-government was one of the most debated problems of Church life in that period. The public discussion was initiated by D.F. Samarin (1827-1901). He formulated the “social concept” of the parish and parish reform, based on Slavophile views on society and the Church. In the beginning of the twentieth century his eldest son F.D. Samarin who was a member of the Special Council on the development the Orthodox parish project in 1907, and as such developed the Slavophile concept of the parish. In 1915, A.D. Samarin, who took up the position of the Chief Procurator of the Most Holy Synod, tried to make his contribution to the cause of the parish reforms, but he failed to do so due to his resignation.

Waqf has two dimensional meaning; the spiritual dimension that is taqarrub to Allah and the social dimension as the source of Islamic financial for the welfare of the people. Waqf disputes can be caused by several reasons; waqf land is not accompanied with a pledge; waqf is done on the basis of mutual trust so it has no legal proof and ownership. Currently, the choice to use the court is less effective in resolving disputes. Hence, the public ultimately chooses non-litigation efforts as a way to resolve the disputes. Mediation process is preferred by many as it is viewed to be the fairest way where none of the two parties wins or loses (win-win solution). It is also fast and cheap. This study is intended to examine how to solve waqf dispute with mediation model according to the waqf law, and how the application of mediation in the Religious Courts system

"Feminist Interpretations of Action and the Public in Hannah Arendt’s Theory. Arendt’s typology of human activity and her arguments on the precondition of politics allow for a variety in interpretations for contemporary political thought. The feminist reception of Arendt’s work ranges from critical to conciliatory readings that attempt to find the points in which Arendt’s theory might inspire a feminist political project. In this paper I explore the ways in which feminist thought has responded to Arendt’s definition of action, freedom and politics, and whether her theoretical framework can be useful in a feminist rethinking of politics, power and the public realm. Keywords: Hannah Arendt, political action, the Public, the Social, feminism "

Subject. The article provides considerations on the formation and development of a successful person model in the modern Russian society. Objectives. The study is an attempt to model a successful person in the Russian society, when the ideological subsystem of the institutional matrix is changing. Methods. The study relies upon the theory of institutional matrices by S. Kirdina, theories of human and social capital. We focus on the assumption viewing a person as a carrier of social capital, which conveys a success, socio-economic position, social status, civic activism, doing good to your family and the public, confidence in people and association with your region. The empirical framework comprises data of the sociological survey of the Russian population in 2018. The data were processed through the factor analysis. Results. We devised a model of a successful person in today's Russian society, which reveals that a success, first of all, depends on the economic wellbeing and has little relation to civic activism. The potential involvement (intention, possibility, preparedness) in the social and political life significantly dominates the real engagement of people. The success has a frail correlation with constituents of the social capital, such as confidence in people and doing good to the public. Conclusions and Relevance. Based on the socio-economic wellbeing, that is consumption, the existing model of a successful person proves to be ineffective. The sustainability of socio-economic wellbeing seriously contributes to the social disparity of opportunities, which drive a contemporary Russian to a success in life.

Dr. C.K. Clarke (1857-1924) was one of Canada’s most prominent psychiatrists. He sought to improve the conditions of asylums, helped to legitimize psychiatry and established formal training for nurses. At the beginning of the 20th Century, Canada experienced a surge of immigration. Yet – as many historians have shown – a widespread anti-foreigner sentiment within the public remained. Along with many other members of the fledgling eugenics movement, Clarke believed that the proportion of “mental defectives” was higher in the immigrant population than in the Canadian population and campaigned to restrict immigration. He appealed to the government to track immigrants and deport them once they showed signs of mental illness. Clarke’s efforts lead to amendments to the Immigration Act in 1919, which authorized deportation of people who were not Canadian-born, regardless of how many years that had been in Canada. This change applied not only to the mentally ill but also to those who could no longer work due to injury and to those who did not follow social norms. Clarke is a fascinating example of how we judge historical figures. He lived in a time where what we now think of as xenophobia was a socially acceptable, even worthy attitude. As a leader in eugenics, therefore, he was a progressive. Other biographers have recognized Clarke’s racist opinions, some of whom justify them as keeping with the social values of his era. In further exploring Clarke’s interest in these issues, this paper relies on his personal scrapbooks held in the CAMH archives. These documents contain personal papers, poems and stories that proclaim his anti-Semitic and anti-foreigner views. Whether we allow his involvement in the eugenics movement to overshadow his accomplishments or ignore his racist leanings to celebrate his memory is the subject of ongoing debate. Dowbiggin IR.

The article reveals the conceptual foundations of the social responsibility of the court as an important prerequisite for the legal responsibility of a judge. It has been established that the problem of court and judge liability is regulated by the following international and Ukrainian documents, such as: 1) European Charter on the Law «On the Status of Judges» adopted by the Council of Europe; 2) The Law of Ukraine «On the Judicial System and the Status of Judges»; 3) the Constitution of Ukraine; 4) The Code of Judicial Ethics, approved by the Decision of the XI (regular) Congress of Judges of Ukraine; 5) Recommendation CM/Rec (2010) 12 of the Cabinet of Ministers of the Council of Europe to member states regarding judges: independence, efficiency and responsibilities; 6) Bangalore Principles of Judicial Conduct. The results of a survey conducted by the Democratic Initiatives Foundation and the Razumkov Center, the Council of Judges of Ukraine and the Center for Judicial Studios with the support of the Swiss Agency for Development and Cooperation based on the «Monitoring of the State of Independence of Judges in Ukraine – 2012» as part of the study of the level of trust in the modern system were considered and analyzed, justice, judges and courts. It is determined that a judge has both a legal and a moral duty to impartially, independently, in a timely manner and comprehensively consider court cases and make fair judicial decisions, administering justice on the basis of legislative norms. Based on the study of the practice of litigation, it has been proven that judges must skillfully operate with various instruments of protection from public influence. It has been established that in order to ensure the protection of judges from the public, it is necessary to create special units that will function as part of judicial self-government bodies. It was proposed that the Council of Judges of Ukraine, which acts as the highest body of judicial self- government in our state (in Ukraine), legislate the provision on ensuring the protection of the procedural independence of judges.
