Comparison and classification of flexible distributions for multivariate skew and heavy-tailed data

We present, compare and classify popular families of flexible multivariate distributions. Our classification is based on the type of symmetry (spherical, elliptical, central symmetry or asymmetry) and the tail behaviour (a single tail weight parameter or multiple tail weight parameters). We compare the families both theoretically (relevant properties and distinctive features) and with a Monte Carlo study (comparing the fitting abilities in finite samples)

Psychosocial support in emergency situations

In recent decades we have witnessed a growing number of major accidents and emergencies caused by natural hazards (floods, earthquakes, cyclones) and human factors (chemical and nuclear accidents, conflicts, terrorism). In such situations, people’s lives are fundamentally changed and accompanied by various social consequences: loss of loved ones, loss of control over one’s own life, loss of the sense of security, hope and initiative, social infrastructure, access to services and assets. Reactions may be various; shock, tears, anger, rage, a sense of hopelessness and an anxiety are just part of the whole range of unpleasant experiences. However, the intensity of the stress responses differs among individuals, but also communities, and thus the needs for interventions are different. The role of organizations dealing with the protection and rescue is to provide immediate assistance and protection, and also psychosocial assistance and support. The psychosocial support is the process of facilitating the recovery of individuals, family and communities from the effects of hazards and it plays a key role in the interventions at major accidents involving large number of victims. Psychosocial support means that in the approach to a person two dimensions are involved influencing each other mutually: psychological (inner, emotional and meditative processes, feelings and reactions of individual) and social (relationships with other people, family networks, social values and culture of the community). The third dimension involves the first responders. Stress can initiate the development of depression, depressive disorders, anxiety, professional burn-out, depersonalization, distress, emotional exhaustion and related mental health problems, as well as other indicators of psychological distress among members of rescue teams. Bearing in mind the importance of psychosocial programs of the nineties, their implementation is supported in many projects and it is proposed that the psychosocial care becomes an integral part of the emergency response of the public health care system

SOCIAL ENTREPRENEURSHIP AND ECONOMIC DEVELOPMENT

The time in which we currently live and will continue to live is a time of changes, which are comprehensive, deep and quick. They occur in almost all spheres and areas of human activity and life. Regardless of their causes, they are all structural changes whose consequences are primarily economic in their nature. The last three decades have been characterized by a rather significant increase in entrepreneurial activities, which is why they are often referred to as "the age of entrepreneurship", "entrepreneurial revolution" and "entrepreneurial renaissance". Enthusiasm towards the role of entrepreneurship in the economic development has had an impact on the development of social entrepreneurship in the last few decades. Thus, the new entrepreneurial culture has also spread to the social sector. Increasingly higher expectations are being set on social entrepreneurship in terms of addressing the needs in the social sector and achieving socio-economic security. Social entrepreneurship implies innovative and financially sustainable activities targeted at social problems. However, its commercial activities do not necessarily need to coincide with the social mission; rather, their purpose is to create financial resources to implement social objectives. Thus, social entrepreneurship can encompass a rather broad range of organizations and businesses – ranging from those which generate their own profit to those which obtain resources for other organizations that fulfill the social mission. This paper will explain the importance of the social entrepreneurship concept, entrepreneurship with moral and ethical integrity, criteria for its classification, as well as criticism of this concept. In the end, an overview of development of social entrepreneurship in the Republic of Croatia and in the world

University characteristics as the success factor of academic spin-offs

The complexity of knowledge-based society is constantly adding new challenges for higher education institutions. Entrepreneurial university model is developed in such a way that it incorporates the additional role of the commercialization of knowledge and active contribution to the development of private enterprises in the local and regional economy. The main objective of the paper is to explore the characteristics of university which support entrepreneurial activities and facilitate the generation and exploitation of knowledge and technology. The main research question is how the university can become an incentive factor for the development and success of academic spin-off ventures? The results of the research have shown that the characteristics of the social and institutional environment influence the development and success of academic spin-off ventures by developing various mechanisms that encourage innovation and entrepreneurship. In addition, the research has shown that the university, by strengthening the culture of academic entrepreneurship as well as, by establishing cooperation with industry and public institutions on all levels, encourages the development of academic spin-off ventures. In the concluding observations, we emphasized the importance of further research in the field of higher education institutions, in order to provide additional contribution to the literature focused on academic entrepreneurship, as well as to provide practical recommendations for improving the success of academic spin-offs

Reaktivna i spontana agresivnost mladih

Introduction/ The aim of the work. The aim of the research is to determine the degree of severity of reactive and spontaneous aggressiveness of the young. The specific objective of this study was to determine gender differences in the expression of reactive and spontaneous aggression of the young and the reactions of parents to their aggressiveness. Method. The research was done on a sample of 91 examinees, secondary school students of Gymnazium “Bora Stankovic” in Vranje, aged 16-18 years. The research consisted of 52 male (57%) and 39 female examinees (43%). Testing, which took 20 - 30 minutes, was performed by the school psychologist, in a regular class, with a standardized Practice Test. The degree of reactive and spontaneous aggression was measured by two scales of a standardized Freiburg personality test (FPI). This research was done in 2014. The processing of the data was carried out by using the SPSS program package, version 11.5. Results are shown by using methods of statistical description: frequency distribution, average score values, standard deviations and percentages. The significance of differences was shown using the t-test and Chi square tests. The limit of statistical significance is less than 5 % (p lt 0.05). Results. The data show that young men have more reactive, spontaneous, and overall aggressiveness, compared to girls. In the dimension of spontaneous aggression boys show significantly higher statistical values, compared to the girls (p lt 0.05). In response to the aggression of young people, their parents often use verbal aggression and apply prohibitions. It is important to note that 4-6 % of the parents don’t not respond at all to the aggressiveness of their children nor do they use corporal punishment. Conclusion. Obtained results point to the need for more prevention work with young people for increasing awareness and control of aggressive motives and awareness raising in terms of non-violent forms of behavior. It is important to increase the role of school in advisory work with parents whose children are expressing a high degree of aggressive behavior.Uvod/Cilj rada. Cilj istraživanja je da se utvrdi stepen izraženosti reaktivne i spontane agresivnosti mladih. Poseban cilj istraživanja bio je da se utvrde polne razlike u izražavanju reaktivne i spontane agresivnosti mladih i načini reagovanja roditelja na njihovu agresivnost. Metod. Istraživanje je rađeno na uzorku od 91 ispitanika, učenika Gimnazije “Bora Stanković” u Vranju, starosti od 16-18 godina. Uzorak je sastavljen od 52 ispitanika muškog pola (57%) i 39 ispitanika ženskog pola (43%). Testiranje je obavio psiholog škole, na redovnom času, sa standarizovanim uputstvom za rad testa, u trajanju od 20-30 minuta. Stepen izraženosti reaktivne i spontane agresivnosti meren je dvema skalama iz standardizovanog Frajburškog testa ličnosti (FPI). Istraživanje je sprovedeno 2014. godine. Obrada podataka je urađena upotrebom programskog paketa SPSS u verziji 11,5. Rezultati su prikazani metodama statističke deskripcije: distribucijom frekvencije, srednje vrednsti, standardne devijacije i procentima. Značajnosti razlika su rađene t-testom i Hi kvadrat testom. Granica statističke značajnosti je manja od 5% (p lt 0,05). Rezultati. Dobijeni podaci ukazuju da mladići imaju veću reaktivnu, spontanu i ukupnu agresivnost, u odnosu na devojke. U dimenziji spontane agresivnosti mladići imaju statistički značajno veće vrednosti, u poređenju sa devojkama (p lt 0,05). Na agresivnost mladih roditelji najčešće reaguju verbalnom agresijom i zabranama. Značajno je da 4-6% roditelja uopšte ne reaguje na agresivnost svoje dece ili koristi fizičku kaznu. Zaključak. Dobijeni rezultati ukazuju na potrebu dodatnog preventivnog rada sa mladima u osvešćivanju i kontroli agresivnog motiva i razvijanje svesti o nenasilnim oblicima ponašanja. Značajno je povećati ulogu škole u savetodavnom radu sa roditeljima čija deca izražavaju visok stepen agresivnog ponašanja

Impact of the process of polymerization of polyol and toluen diisocyanate on the environoment

The aim of this study was to investigate the impact of the process of polymerization of polyiol and tolyendiisocyanate on the environoment. Toluene diisocyanates are important industryal intermediates used in conjunction with polyether and polyester polyols as coreactants polyurethane foams, paints, varnishes, elasomers and coatings. This presentation summarizes existing information on the release and behavior of the process of polymerization of polyol and toluen diisocyanate on the environment. A major reaction of TDI in the environoment is formation of solid inert polyureas from reaction with water. In use, TDI is reacted with polyols to form many different polyurethane products. Polyurethanes have been show to be stable in the environment and in disposal have no adverse impact on municipal waste handling processes, landfills or incineration.Physical chemistry 2006 : 8th international conference on fundamental and applied aspects of physical chemistry; Belgrade (Serbia); 26-29 September 200

Religiousness level and citizen preparedness for natural disasters

The subject of quantitative research was examination of relationship between the level of religiousness and perception of citizen's flood disaster preparedness. The aim of such research was a scientific explanation of relationships of these characteristics and the perception. Bearing in mind all local communities in Serbia, where floods occurred or there is a high risk of flooding, the sample including 19 of 150 municipalities and 23 towns was randomly selected, as well as the city of Belgrade, where 2,500 persons were surveyed in 2015. The research included the following communities: Obrenovac, Šabac, Kruševac, Kragujevac, Sremska Mitrovica, Priboj, Batočina, Svilajnac, Lapovo, Paraćin, Smederevska Palanka, Jaša Tomić, Loznica, Bajina Bašta, Smederevo, Novi Sad, Kraljevo, Rekovac and Užice. The research of selected communities was undertaken in the areas which were most affected in relation to the amount of water or potential risk of flooding. The survey used strategy of testing in households with the use of a multistage random sample. The parts in the administrative headquarters, which were threatened by hundred-year-old water or a potential risk of high water were determined in the first stage. In the second stage streets and their parts were established, and in the third stage the households in which the survey was conducted were determined. The number of households was coordinated with the size of the community. The fourth stage of sampling referred to the procedure of respondent selection within previously defined household. The respondent selection was conducted using a random sampling method on the adult household members, who were present at the time of the survey. The results indicate that there is a statistically significant correlation level of religiosity with perception in terms of citizens' preparedness to respond. The research results can contribute to the improvement of citizens' preparedness to respond to such events and can be used to develop the strategy for enhancement of the level of citizens' preparedness to respond
