Published: September 2018

Introdução: A audibilidade, medida pelo SII (Índice de Inteligibilidade de fala), tem se mostrado uma condição necessária para o desenvolvimento de linguagem, pois permite o acesso ao input linguístico. O desenvolvimento de vocabulário tem provado ser um bom indicador do desenvolvimento de linguagem. Objetivo: investigar as características audiológicas e de desenvolvimento de linguagem oral em crianças com deficiência auditiva usuárias de aparelho de amplificação sonora individual. Método: Foram avaliadas 65 crianças entre 6 e 17 anos, usuárias de aparelho de amplificação sonora individual, quanto ao desempenho de vocabulário receptivo (Peabody Picture Vocabulary Test - PPVT-4) e audibilidade (SII 65). Resultados: A audibilidade para sons de fala revelou que, 9% dos sujeitos tinham SII 65 menor que 37, 47% tinham SII 65 entre 38 e 57 e 43% maior que 58. A pontuação média de escore padrão no teste de vocabulário foi de 51,8 pontos. Ao relacionar a audibilidade com o vocabulário, a tendência linear de aumento no desempenho de vocabulário com o aumento da audibilidade não foi significativa. Conclusões: As características e heterogeneidade da população pareceram representar as diferentes condições dos sujeitos acompanhados em um serviço de saúde auditiva no Brasil. Para a população estudada, a audibilidade não determinou o desempenho do vocabulário, sendo condição necessária, mas não suficiente para o desenvolvimento e crescimento do vocabulário.

The process of social manipulation of modern youth is the object of the study. Foreign intelligence services, international organizations and the media, supported by them as agents of the process of social manipulation of young people is the subject of the research. The relevance of the research topic is due to the fact that in the conditions of the systemic crisis of the basic institutions and institutions of socialization of modern Russian society, there is an urgent need to develop effective mechanisms to counter the manipulative effects of various, not unambiguous subjects of social life. These subjects use young people as an object of manipulation, as well as testing of political, social and psychological technologies and experiments on them. In this context, the systematization of relevant scientific knowledge about the activities of foreign intelligence agencies, international organizations and the media, supported by them as important subjects of social manipulation, is an important task facing modern Russian society and science. The analysis of the activities of these agents of social manipulation confirmed the relevance, novelty and prospects of the development of this problem, as well as the urgent need to limit the influence of these actors on the political life of Russian society, as well as the younger generation of our country.

Authors: Shipunova T. V.
Published: September 2018

The article is devoted to one of the most urgent problems of the social life – to the identifying the risks of young people’s deviance. For modern Russian realities, the growth of deviant phenomena in a given social group is characteristic. This testifies to the shortcomings of the organization of preventive social control, which is not limited to the development of a policy on prevention, but is more dependent on professional practices and ideas about the risks of deviance in the discourses of various control agents. The article presents the main approaches to understanding risks, the importance of studying risks in everyday professional practices of control agents is examined. The main attention is paid to the presentation of the research results, the purpose of which was to identify the general and specific in the content of discourses of social control agents regarding the risks of deviance of youth. The discourses of the main agents of control – police, school, social service institutions (state and non-state) are considered. The author comes to the conclusion that in the police and teacher discourses, an institutional approach, involving the use of external control of behavior, is predominantly used. The discourse of social security institutions is closer to the modern concepts of riskand protective factors, based on the need to consider life situations of youth and the development of internal control. This article may be of interest to specialists working in the field of the sociology of youth, the sociology of the family, social work, as well as to representatives of all agents of preventive social control.

Theories of reference group and revolution: general theoretical matrix of relative deprivation
Authors: Svishcheva A. N.
Published: September 2018

The article is an overview of the first stage in the development of relative deprivation theories during the 1940–1970s: theories of reference group and revolution. The concepts of “relative deprivation” and “reference group” appeared in 1949 and 1942, respectively. Further specification of reference group concept statements by H. Hyman, R. Merton, W. Runciman, R. Williams contributed to the formulation of relative deprivation theory. The definition of the forms of reference objects (individual, collective, social category), types of comparisons, essence and functional types of reference groups (comparative, normative, identification, and audience) allowed to describe types of relative deprivation, its essence, content (cognitive and affective), and also it’s levels: individual and group. However, reference group theorists have also identified a lot of problematic issues requiring further scientific development. One such issue, problems of relative deprivation formation, is considered within the framework of the theories of revolution through the analysis of social changes. Within the theories of revolution of the 1960s–1970s two approaches of understanding the essence of relative deprivation have emerged: theories of frustrationaggression (T. Gurr, J. Davies, D. Lerner, I. and R. Feierabends) and status inconsistency (J. Urry, C. Johnson, E. Hoffer). Works of the adherents of the first approach have made it possible to expand the field of relative deprivation study, but also they have become the subject of wide criticism. Focusing on the reference group theory and problems of collective identity research J. Urry’s approach was better integrated into the tradition of relative deprivation studying.
Transformation of types of religiosity in the context of globalization
Authors: Trophimov S. V.
Published: September 2018

The article outlines the transformation of types of religiosity in the conditions of modern Western society. An assessment of the religious situation in contemporary Western society at the end of the 20th century and some examples are given. Particular attention is paid to the crisis of secular regulation of religion in modern society. Paradoxically, the weakening of the regulatory capacity of religious institutions leads to a weakening of the secular state. Religion, displaced into the private sphere, undergoes significant transformations. The active expansion of neoliberal ideology through the leading actors of globalism has significantly changed the nature of the socialization of individuals, their relation to the world and the ability to communicate. As a result of the principles of freedom of conscience and religious pluralism enshrined in both constitutions and in public morals, the individual’s right to choose his religious beliefs is generally accepted, and therefore the human right to form a religious identity proves to be primary in relation to a religious tradition controlled by institutions. If earlier the younger generation accepted the experience of the older generations, partially modifying it, but on the whole following it and finding in it suitable models of behavior, today the main emphasis is given to individual experience, shared with others, and acceptance of personal responsibility. Even adherents of traditional confessions themselves bring to their religious practice elements of eastern religions and esotericism, but discard elements of their own traditions that they consider “out-ofdate” or “do not fit into the way of modern life”. The institutional crisis of the establishment of the truths of faith favors the increase in the number of belief systems of individual communities. In a changing religious situation, the state should seek a new model of interaction with religious organizations and groups. The material is provided useful for comparative studies of the religious situation in Russia and Western Europe.
Reproductive history as a predictor of reproductive behavior
Authors: Karpova V. M.
Published: September 2018

The article is devoted to the analysis of actual tendencies of reproductive behavior, change of birth rate indicators, frequency of induced abortion and births’ loss for natural reasons. The significance of reducing reproductive losses, both by of reducing the number of induced abortions, and by improving women’s reproductive health is shown. The article contains dynamic statistical data on the indicators of reproductive behavior, comparisons are made with similar indicators of other countries, to clarify the characteristics of reproductive behavior of Russians. The data of sociological surveys conducted by leading research centers on the attitude of the population to various lines of reproductive behavior are also given. Based on the analysis of the survey data, it is shown that, despite declared disapproval of abortions, people in general are not ready to assume the financial responsibility for making such a decision. Based on the regression analysis of reproductive histories of 2935 women, who participated in a series of studies conducted under the chair of the Sociology of Family and Demography, the influence of previous reproductive behavior on the outcome of pregnancy was analyzed. It is shown, that in addition to known medical patterns, a number of behavioral and values’ system factors that increase the likelihood of a child’s birth can be identified. Regression analysis showed that the growth of reproductive attitudes not only leads to an increase in the likelihood of a child’s birth against artificial abortion, but also has a positive effect on reducing the probability of spontaneous abortion. The significant negative impact of the existing number of children on the likelihood of choosing a birth against induced abortion was shown. This result confirms spread of lowfertility norms and childbearing termination after the need in children and their specific number is satisfied.

Authors: Novoselova E. N. , Liadova A. V.
Published: September 2018

The article examines the main trends and forecasts of Africa’s development. The global inequality is seen by the authors as a key factor threatening the continent today and the future. As it shows by the authors, the global inequality influences on the development of Africa differentlly: by social, economical, ecological, political aspects. The certain aspects and statistical characteristics of inequality such as poverty, resources’ deficit (food shortages and water crisis) are analyzed by the present study. Degradation of the environment is happening due to the irrational use of nature that becomes an inhibitory factor in development of the African continent. A comprehensive analysis of current and forecasted demographic indicators has been carried. Africa’s role in the future demographic processes has been characterized, considering that the continent is of the rising “demographic giants”. Migration processes from Africa to the European Union countries has been assessed, as well as the prospects of an increasing inflow of migrants from Africa to Russia. As a consequence of demographic influence together with the adverse environmental impact, the authors point to extremely low standard of living, social inequality, disordered urbanization. However, despite the fact that Africa in the early 21st century is associated with conflicts (interstate and civil wars, inter-ethnic clashes), uncontrolled migration, insurmountable poverty, environmental disasters, hunger, deadly diseases, drug production and export, the authors note that global interest in Africa and the economic community first of all significantly increases in the third millennium. It is concluded that there is a need for a balanced assessment of the main risks and benefits of Russian-African relations at the present stage. Future planning of Russian-African relations must to take into account both the tremendous natural resources and demographic potential of Africa together with the global challenges and threats it bears.
The Environmental, Social and Governance Aspects of Social Responsibility Indices – A Comparative Analysis of European SRI Indices
Authors: Mikołajek-Gocejna Magdalena
Published: September 2018

An increasing number of investors want to invest their capital not only with profit but also responsibly, and they pay significant attention to the formula of socially responsible investing (SRI), which means that they consciously engage their funds in companies operating in accordance with CSR principles. An important influence on the development of CSR is the role of stock exchange indices on socially responsible companies. These indices can be considered specific tools for adapting this concept in practice, in particular in the field of socially responsible investment. This article provides a comparative analysis of the social, environmental and governance criteria underlying the definition of the composition of selected European SRI indices. The research will cover the following indices: the DJSI Europe Index, the FTSE4Good Europe 40, the FTSE4Good Europe 50, the EURO STOXX Sustainability 40 and the Solactive Sustainability Index Europe. This paper also intends to set an index reflecting the degree to which companies of certain European countries are represented in major European SRI indices. Consequently, global and national initiatives and ratings were excluded, as well as sector‑and industry‑specific initiatives and ratings. The proposed index is standardized by introducing the GDP of each country into the calculation formula as a way to a achieve comparable result. We believe that the proposed metric will reflect the state of the art in SRI and provide an overall picture of SRI practices across nations.
Island tourism during the global economic crisis
Authors: Podhorodecka Katarzyna
Published: September 2018

The purpose of this article was to observe the relationship between the tourism movement and the economic development of island territories during the global economic crisis (2008-2010). The aim of the paper was also answer the questions: why did some island territories react differently to the global economic crisis and if the coefficient of variation is a good indicator for assessing the changes in tourism movement during crisis events. Countries that have larger tourism expenditures as a proportion of GDP had a weak relationship between changes in tourist arrivals and changes in GDP. The islands prone to the global economic crisis did not have a stronger correlation between changes in tourist arrivals and GDP. The coefficient of variation was a good measure to indicate the island regions that were characterized by major changes in the volume of tourist movements.

Authors: Besic Nikola , Dremelj Marta , Pilko Gasper
Published: September 2018

Background

Locoregional recurrence is common in patients with locally advanced differentiated thyroid carcinoma (DTC). Our aim was to find out the rate of locoregional control of the disease after external beam radiotherapy (EBRT) of the neck and mediastinum in patients with DTC and pT4 tumor.

Patients and methods

Altogether 91 patients (47 males, 44 females, median age 61 years) with DTC had EBRT of the neck and mediastinum as part of the multimodal treatment of pT4 tumor (63 cases pT4a, 28 cases pT4b) from the year 1973 to 2015. Data on clinical factors, histopathology and recurrence were collected. Disease-free, disease-specific and overall survival was calculated.

Results

Median tumor size was 5 cm (range 1–30 cm). Out of 91 patients, 23 had distant and 38 regional metastases. A total or near-total thyroidectomy, lobectomy, subtotal thyroidectomy and lymph node dissection was performed in 70%, 14%, 2% and 30% of cases, respectively. Thirteen percent of patients were not treated with surgery. All patients had EBRT and 39 had chemotherapy. Radioiodine (RAI) ablation of thyroid remnant and RAI therapy was applied in 90% and 40% of cases, respectively. Recurrence was diagnosed in 29/64 patients without a persistent disease: locoregional and distant in 16 and 13 cases, respectively. Five-year and ten-year disease-free survival rate was 64% and 48%, respectively.

Conclusions

The majority of patients with DTC and pT4 tumors who were treated with EBRT of the neck and mediastinum region as part of multimodal treatment have long-lasting locoregional control of the disease.

Student Teachers as Future Researchers: How do Hungarian and Austrian Initial Teacher Education Systems Address the issue of Teachers as Researchers?
Authors: Pesti Csilla , Győri János Gordon , Kopp Erika
Published: September 2018

Even though initial teacher education is a rather short period in comparison to the other phases of a teacher’s career, it has a crucial role in shaping student teachers’ career-long activities. Many argue that everyday teaching in a classroom setting is comparable to conducting research, as teachers pursue experimenting with different strategies to teaching and learning, as they reflect on their own as well as their colleagues’ work, and as they make decisions about their future steps based on these experiences. This paper aims to reveal how the concept of teachers as researchers is addressed in initial teacher education programmes by answering two questions: How is the concept of teachers as researchers represented in these programmes? What kind of experiences do student teachers have regarding practice-oriented research? The research has a case study design with a comparative aspect, in which one Hungarian and one Austrian institution offering initial teacher education serve as the two cases. Results show that both universities have integrated research into their initial teacher education programmes, but in different ways and to different extents. An important notion is that although various courses that deal with research and/or research methodology and could contribute to the development of student teachers’ research competences could be identified, the activities of these courses are somewhat restricted to taking place within the university walls (e.g., discussion of research results), detached from practice. The study is expected to contribute to the understanding of structural similarities and differences in initial teacher education systems in the two countries that may foster or hinder the development of student teachers’ development during their school-based teaching practice, with a particular focus on those that are required to conduct practice-oriented research.
Using Least Mean p-Power Algorithm to Correct Channel Distortion in MC-CDMA Systems
Authors: Zidane Mohammed , Safi Said , Sabri Mohamed , Frikel Miloud
Published: September 2018

This work focuses on adaptive Broadband Radio Access Network (BRAN) channel identiﬁcation and on downlink Multi-Carrier Code Division Multiple Access (MCCDMA) equalization. We use the normalized BRAN C channel model for 4G mobile communications, distinguishing between indoor and outdoor scenarios. On the one hand, BRAN C channel parameters are identiﬁed using the Least Mean p-Power (LMP) algorithm. On the other, we consider these coeﬃcients in the context of adaptive equalization. We provide an overview and a mathematic formulation of MC-CDMA systems. According to these fundamental concepts, the equalizer technique is investigated analytically to compensate for channel distortion in terms of the bit error rate (BER). The numerical simulation results, for various signal-to-noise ratios and diﬀerent p threshold, show that the presented algorithm is able to simulate the BRAN C channel measured with different accuracy levels. Furthermore, as far as the adaptive equalization problem is concerned, the results obtained using the zero-forcing equalizer demonstrate that the algorithm is adequate for some particular cases of threshold p.
