Public relations give opportunity to the organization to present its image and personality to its own “public”- users, supporters, sponsors, donors, local community and other public.It is about transferring the message to the public, but that is a two-way street. You must communicate with your public, but at the same time you must give opportunity to the public to communicate easier with you. The real public relations include dialog – you should listen to the others, to see things through their perspective. This elaborate is made with the purpose to be useful for every organization, not for the sensa-tional promotion of its achievements, but to become more critical towards its work. Seeing the organization in the way that the other see it, you can become better and sure that you are giving to your users the best service possible.

Riba is an economic activity that is prohibited by the Qur’an. Chronologically, the ban has been outlined clearly. On the other hand, bank interest that become one pillar of the existence of financial institutions is rated synonymous with usury. Financial institutions have become a pillar of economic growth. The problem is why the Qur’an forbids usury, whereas various economic activities ‘need’ the existence of interest that are identical to the usury. This study found two findings. First, the prohibition of riba in the Qur’an have preceded other forms of restrictions are more morally intolerable that broadly impacts a major disadvantage in the community. On the other side of the Qur’an strongly encourages the public Makkah to help the poor and orphans around him. Second, the prohibition of riba in the Qur’an has relevance to the real sector of the economy. Therefore, the economy based on usury will naturally ignore the underlying transaction which is the basis of the real sector. As a result of the investors (capitalists) certainly fortunate while the money manager/entrepreneur is still no clarity, so that the position is unbalanced, unjust. The usurious economic system can lead to gaps world community economic growth constantly.

This article aims to present a concept of era based on the Qur'anic idea of Al-Ashr. At the first presence, era, whether at historical level, or transcending it, has never escape holiness, as time and space where sacred moral act is always present. At the second presence, era is, in essence, holiness as a reality of being, reality of existence, and presence, where the entire range of the past, present and future is no longer important, even lost, but is a reality that is present in the era without era. At the third presence, holiness, on the other hand, must be historical for the task of the public in the name of love for God, which is part of the deepest consciousness of every human being and human relations where the past, present and future move historically in space and time. At the fourth presence, the real man is thus a man who always purifies his soul without pause in the historical space of time, even beyond it. At the fifth presence, the act of “so be it” (kun fayakun) of God exists, time exists throughout the span of time without any preconditions or constructions based on His commandments (namely Ibn Arabi Bipolar Triplisity).

Definition Of

The article presents a philosophical analysis of the “Catechism of a Revolutionary” in the light of its paradoxically and nihilistic boundedness which resulted in the system of practical actions of S. G. Nechaev, led to the murder of student Ivanov. In this connection the identification of the philosophical foundation of the Catechism of a Revolutionary becomes relevant, as well as the definition of its nature in the scale of textuality and effectiveness. The author proposes to consider the “Catechism of a Revolutionary” as a philosophical text on the basis of the presence of metaphysical and existential aspects in the article. At the same time, the author highlights such key features: a focus on practice (rejection of theorizing in favour of the action “here and now”), substitution of purpose by means (replacing the value of the public weal with total destruction and the paradox of the struggle for equality through formation of a rigid hierarchy), as well as extreme ethical nihilism and cynicism. All these premises allow the author to designate the ideological foundation of the “Catechism of a Revolutionary” as a holistic and consistent philosophy of destruction. In addition, this philosophy is considered in the context of its direct embodiment, implemented by S. G. Nechayev: lie, blackmail, compromising, and most importantly – murder. The author of the article concludes that it is impossible to explore the “Catechism of a Revolutionary” apart from the actual consequences of the implementation of his philosophy, and therefore one cannot speak only of his textual nature, detached from the real life. Instead, it should be considered as a fusion of textuality and effectiveness, which directly transforms being and affects people’s lives. Thus, the “Catechism of a Revolutionary” is presented by the author as a killer-text, consisting of a philosophy of destruction on the one hand and its embodiment into reality on the other. Such an approach allows not only to comprehensively explore the nature of the “Catechism of a Revolutionary”, but also to identify a number of dangers that the philosophy of destruction bears inside.

AbstractThe liberal justification for censorship equates the harm in hate speech with the sort of tangible injury that would justify state intervention under J.S. Mill's harm principle. Recently, Jeremy Waldron has suggested that the real harm perpetuated by hate speech is less tangible, taking it to be a variety of moral pollution which undermines both the public good of inclusiveness and the minority's assurance of personal dignity. This paper scrutinizes Waldron's conception of the harm in hate speech, arguing that it lacks the specificity and gravity Mill's principle requires in order to justify censorship. The paper also questions the categorical distinction between hate speech and speech that is “merely offensive,” arguing that Waldron's reasons for censoring the one also apply to the other. The result is a censorship regime that liberals ought not to accept.

If one of aims of science today is to respond to the real needs of society, it must find a new way to communicate with people and to be acquainted with their opinions and knowledge. Many science museums in Europe are adopting new ways to actively engage the public in the debate on topical scientific issues. The Museum of Science and Technology "Leonardo da Vinci" in Milan (partner of the SEDEC project) has thus experimented some formats for dialogue with teachers and with the public in general. Our experience shows that museums can be places where science and the public on the one hand and democracy on the other meet.

Hidden “holes” in the capital of banks and the supply of credit to the real sector of economy

Our analysis documents that the existence of hidden “holes” in the capital of not yet failed banks - while creating intertemporal pressure on the actual level of capital - leads to changing of maturity of loans supplied rather than to contracting of their volume. Long-term loans decrease, whereas short-term loans rise - and, what is most remarkably, by approximately the same amounts. Standardly, the higher the maturity of loans the higher the credit risk and, thus, the more loan loss reserves (LLP) banks are forced to create, increasing the pressure on capital. Banks that already hide “holes” in the capital, but have not yet faced with license withdrawal, must possess strong incentives to shorten the maturity of supplied loans. On the one hand, it raises the turnovers of LLP and facilitates the flexibility of capital management; on the other hand, it allows increasing the speed of shifting of attracted deposits to loans to related parties in domestic or foreign jurisdictions. This enlarges the potential size of ex post revealed “hole” in the capital and, therefore, allows us to assume that not every loan might be viewed as a good for the economy: excessive short-term and insufficient long-term loans can produce the source for future losses.
