One of the fundamental problems of the world humans live in is that the resources human beings have used to meet their needs are limited. These resources, when used correctly, are enough to meet these needs. The main problem here is the mistakes human beings make and them not being aware of making these. In other words, they are consciously or unconsciously destroying the world they live in with every action they have taken to create the civilization. In this study, we will focus on the subjects of damages brought out to the natural sources by agricultural and aquacultural production which is used to meet the need for food, and wiping the effects of these damages. In this context, we will also focus on the conditions of the organic agriculture principle application on aquacultural production, which has emerged as a solution to the threats targeting human health and to the environmental problems brought out by the agricultural production.

Abstract. This research took place just after the end of the protests following the killing of a 16-year-old boy by a policeman in Greece in December 2008. Participants (N = 224) were 16-year-olds in different schools in Attiki. Informed by the Politicized Collective Identity Model ( Simon & Klandermans, 2001 ), a questionnaire measuring grievances, adversarial attributions, emotions, vulnerability, identifications with students and activists, and questions about justice and Greek society in the future, as well as about youngsters’ participation in different actions, was completed. Four profiles of the participants emerged from a cluster analysis using representations of the conflict, emotions, and identifications with activists and students. These profiles differed on beliefs about the future of Greece, participants’ economic vulnerability, and forms of participation. Importantly, the clusters corresponded to students from schools of different socioeconomic areas. The results indicate that the way young people interpret the events and the context, their levels of identification, and the way they represent society are important factors of their political socialization that impacts on their forms of participation. Political socialization seems to be related to youngsters’ position in society which probably constitutes an important anchoring point of their interpretation of the world.

With signs of normalization seemingly in place in the world economy, a number of problems show the possibility of aggravation in the future. The volume of derivatives in American banks grows significantly, high risk instruments are back in place and their use becomes more active, global imbalances increase. All of the above requires thorough approaches when creating mechanisms which can neutralize external shocks for the Russian economy and make it possible to develop in the new post-crisis environment.

The article examines the epistemological roots of conservative ideology, development trends and further prospects in political reform not only in modern Russia, but also in other countries. The author focuses on the “world” and Russian conservatism. In the course of the study, the author illustrates what opportunities and limitations a conservative ideology can have in political reform not only in modern Russia, but also in the world. In conclusion, it is concluded that the prospect of a conservative trend in the world is wide enough. To avoid immigration and to control the development of technology in society, it is necessary to adhere to a conservative policy. Conservatism is a consolidating ideology. It is no coincidence that the author cites as an example the understanding of conservative ideology by the French due to the fact that Russia has its own vision of the ideology of conservatism. If we say that conservatism seeks to preserve something and respects tradition, we must bear in mind that traditions in different societies, which form some kind of moral imperatives, cannot be a single phenomenon due to different historical destinies and differing religious views. Considered from the point of view of religion, Muslim and Christian conservatism will be somewhat confrontational on some issues. The purpose of the work was to consider issues related to the role, evolution and prospects of conservative ideology in the political reform of modern countries. The author focuses on Russia and France. To achieve this goal, the method of in-depth interviews with experts on how they understand conservatism was chosen. Already today, conservatism is quite diverse. It is quite possible that in the future it will transform even more and acquire new reflections.

The world-wide use of scleral contact lenses has dramatically increased over the past 10 year and has changed the way that we manage patients with corneal irregularity. Successfully fitting them can be challenging especially for eyes that have significant asymmetries of the cornea or sclera. The future of scleral lens fitting is utilizing corneo-scleral topography to accurately measure the anterior ocular surface and then using software to design lenses that identically match the scleral surface and evenly vault the cornea. This process allows the practitioner to efficiently fit a customized scleral lens that successfully provides the patient with comfortable wear and improved vision.

The article discusses the meanings of life and value priorities of the post- Soviet society. The author argues that, at present, there are symptoms of a global ideological crisis in the world, that the West does not have its own vision of where and how to move on and has no understanding of the future. Unfortunately, most of the post-Soviet countries do not have such vision as well. In these conditions, there are mistrust, confusion, paradoxical manifestation of human consciousness. The main meanings that determine our life-world are: the desire of citizens for social justice and social security, the desire to figure out and understand the basic values of modern society, how honestly and equally the authorities act toward their fellow citizens, and to what extent they reflect their interests. The meanings of life, which are the answers to the challenges of the time, are embodied in the cultural code of each nation, state. The growth points of new values, which will become the basis for the future sustainable development of a new civilization, have yet to be discovered in the systemic transformative changes of the culture. In this process, the emergence of a new system of values that governs human life is inevitable. However, modern technology brings new troubles to humans. It has provided wide opportunities for informational violence and public consciousness manipulation. Nowadays, the scenario that is implemented in Western consumer societies claims to be the dominant scenario. Meanwhile, today there is no country in the world that is a role model, there is no ideal that others would like to borrow. Most post-Soviet states failed to advance their societies to more decent levels of economic development, to meet the challenges of the modern information age, and to provide the population with new high living standards. Therefore, in conditions of growing confrontation, we should realistically understand the world and be ready to implement changes that will ensure sustainable development of the state and society without losing our national identity.

In the Macedonian literary language the analytic da-construction used in an independent clause has a wide range of possible modal meanings, the most common of which are imperative and optative. The present article offers a detailed analysis of the semantics and functions of the Macedonian optative da-construction based on fiction and journalistic texts. The first part of the article deals with the specificities of the optative as a category which primarily considers the subject of a wish. In accordance with the semantic characteristics of this category, optative constructions are used in those discourse text types where the speakers are explicitly designated (the most natural context for the optative is the dialogue). The analysis of the Macedonian material includes instances of atypical usage of the optative da-construction, in which the wish of the subject is not apparent and thereby produces new emotional tonalities perceptible to the reader of a fiction/journalistic text. The study describes Macedonian constructions involving two different verb forms: 1) present tense form (da + praes) and 2) imperfective form (da + impf). These constructions formally designate the hypothetical and counterfactual status of the optative situation, respectively. Thus, the examples in the analysis are ordered according to two types of constructions, which reflect the speaker’s view on the probability of the realisation of his/her wish. Unrealistic wishes can be communicated through the present da-construction, while the imperfective construction denotes situations in which the wish can be realised in the future. The second part of the article is devoted to performative optative da-constructions, which express formulas of speech etiquette, wishes and curses. The analysis demonstrates that these constructions lose their magical functions, when used outside of the ritual context, and begin to function as interjections.

The biggest challenge faced by students nowadays and in the future, is how to deal with the increasingly high competition in the world, the increasing number of undergraduate and limited job opportunities. In this kind of situations, the students had to find a creative way and change the approach of being a university graduate looking for a job, to become scholars who can create their own jobs, or even able to create jobs for others. The purpose of this study was to determine the youth interest on entrepreneurship in Indonesia. It seems that the youth are unaware to see that the job is increasingly difficult to find nowadays. So through this study, researchers wanted to find out what causes youth in Indonesia, reluctant to become an entrepreneur. While being an entrepreneur, the youth can open or create jobs for others and can reduce the level of unemployment in Indonesia. Self-confidence is an important factor in entrepreneurship. Family environment and quality education also participate in creating interest for youth in entrepreneurship. This research is using basic research method; where researchers will try to link the theories of the existing variables. Thus, researchers can conduct research by distributing questionnaires to the youth throughout Indonesia. This study aims to determine the cause of Indonesian youth lack of interest in entrepreneurship.
