Is the role of academics as teachers changing? An exploratory analysis in Italian universities
Authors: Barbato Giovanni , Moscati Roberto , Turri Matteo 
Published: May 2019

University teaching is under pressure to evolve in line with the social, cultural and economic changes of modern society. This process inevitably affects the professional profile of academics since it creates an increasing tension between the traditional modes of teaching and the learning styles and professional expectations of students. This article analyses, both theoretically and empirically, the process of change of university teachers in the face of today’s challenges. The empirical analysis is based on the Italian university system, which has always been characterised by an overall reluctance to reforms. This article presents a theoretical framework based on two dimensions, i.e., the teacher/university relationship and the teacher/student relationship, to investigate the evolution of the professional profile of academics as teachers on the basis of seven teaching practices identified in the literature. The findings show that, besides some limits that are specific to professional bureaucracies, the support of universities is fundamental to promote innovation in teachers’ teaching practices, which are otherwise regulated and shaped only by their disciplinary community.Received: 14 January 2019Accepted: 27 March 2019Published online: 29 May 2019
COMPARISON OF THE PREVALENCE AND DYNAMICS OF ANXIETY, DEPRESSION AND QUALITY OF LIFE IN PATIENTS WITH CHRONIC RHEUMATIC HEART DISEASE
Authors: Petrov V. S. 
Published: May 2019

The objective. The assessment of the severity, prevalence and five-year dynamics of anxiety and depression in those studied with rheumatic heart disease.Materials and methods. The study included 168 patients with rheumatic heart disease: mean age 58,69±0,47 years; 141 women (83,93%) and 27 men (16,07%). To assess anxiety and depression, the following scales were used: HADS (hospital anxiety and depression scale), CES-D (depression scale of the epidemiological research center), and STAI (Spielberger anxiety scale). Quality of life was assessed using total scale SF-36 (Short Form Medical Outcomes Study), KCCQ (Kansas questionnaire for patients with cardiomyopathy), and MHFLQ (Minnesota questionnaire for the quality of life of patients with CHF).Results. Initially, patients with rheumatic heart disease had mild depression and anxiety, except for the high level of state anxiety according to STAI — 48.00 ± 0.95. More pronounced depressive disorders were revealed in patients with CHF NYHA III and IV. According to CES-D — 17,58±1,27 for FC I and 23,4±0,75 for FC IV, for HADS — 7,00±0,64 for FC I and 13,6±0,78 for FC IV. Anxiety disorders, on the contrary, were less with III and IV FC CHF: 8,5±0,49 with FC I and 8,2±1,02 with FC IV in HADS. According to STAI state anxiety — 47,58±1,22 (FC I) and 42,8±1,76 (FC IV), for trait anxiety — 42,67±1,08 (FC I) and 40,4±1,85 (FC IV). For the five-year period there was no negative and positive dynamics according to the questionnaires of anxiety and depression. The only exception was the increase in anxiety according to HADS by 0.66 points. In terms of quality of life, there was a decrease in physical health according to SF-36 by 1.78, and in overall summary score according to KCCQ by 1.55 and MHFLQ by — 3.99.Conclusions. In patients with rheumatic heart disease, the severity of anxiety and depression is insignificant and does not increase during five years of observation. Indicators of depression are more pronounced in the group with CHF NYHA III and IV, and anxiety indicators in patients with CHF NYHA I and II. An increase in depression rates in subjects with rheumatic heart disease is associated with a deterioration in the quality of life. With an improvement in the quality of life values, depressive symptoms decrease, and anxiety rates increase.

Eagle Ford and Pimienta Shales in Mexico: A Case Study
Authors: Cruz Luque Marcela , Aguilera Roberto 
Published: May 2019

Summary
Our objective in this paper is to highlight the potential of the Eagle Ford (Cretaceous) and Pimienta (Upper Jurassic) shales in Burgos Basin (Mexico) through a comparison with the Eagle Ford Shale in Texas. The comparison is a case study focused on real data and their interpretation, north and south of the border, including geochemistry, geology, production, and reservoir–engineering data.
Our overall approach includes the description of Eagle Ford data in Texas, as well as Eagle Ford and Pimienta data in the Burgos Basin. The geologic comparison is carried out using cross sections of the various formations and geophysical data. Geochemical and petrophysical data are compared using specialized crossplots. Production data are compared through rate transient analysis and by investigating the different flow periods observed in wells in both sides of the border. Reservoir–engineering aspects are compared using material–balance methods developed specifically for analyzing multipurpose shale petroleum reservoirs.
Results indicate that there are many similarities but also some differences between the Eagle Ford Shale in Texas and shales in Mexico. The geologic and seismic cross sections show that there is continuity of the Eagle Ford on both sides of the border. However, structural geology in Mexico tends to be more complex than that in Texas. The geological and geochemical descriptions also show important similarities in the rock mineralogy, and the quantity, quality, and maturity of the organic matter. Well–log data show the same pattern of distribution on modified Pickett plots, developed originally for evaluation of the Eagle Ford Shale in Texas. Production data in the Burgos Basin shales are characterized by long periods (several months or even years) of transient linear flow, something that compares well with the Eagle Ford in Texas. Specialized material–balance calculations, which consider multiple porosities, have been used in the Eagle Ford Shale in Texas and are shown to have similar application in the Burgos Eagle Ford and Pimienta shales. On the basis of the Eagle Ford Shale performance in Texas, and the similarities with Burgos shales, the conclusion is reached that there is significant potential in the Mexican Eagle Ford and Pimienta shales.
We present a comparison of the interpretation of real geoscience and engineering shale data collected on both sides of the border. The comparison is meaningful and suggests that the potential of shale reservoirs south of the border will be quite significant. Mexico should benefit from the lessons learned from the Texas Eagle Ford Shale.
Experimental Quantification of the Effect of Thermal Maturity of Kerogen on Its Wettability
Authors: Jagadisan Archana , Heidari Zoya 
Published: May 2019

Summary
Kerogen is often considered to be fully hydrocarbon–wet in reservoir characterization. However, wettability of kerogen is not well–understood and quantified. Thermal maturation induces changes in the chemical structure of kerogen and alters its oxygen (O) and hydrogen (H) content. This process affects the surface properties of kerogen and can influence its wettability. Assumptions made regarding the wettability of kerogen affect the interpretation of borehole geophysical measurements such as electromagnetic measurements. Therefore, it is important to quantify the wettability of kerogen as a function of its thermal maturity. The objectives of this research are to experimentally quantify the wettability of kerogen at different thermal–maturity levels and to quantify the influence of chemical composition of kerogen on its wettability. To achieve these objectives, kerogen was first isolated from organic–rich mudrock samples from two different formations at different thermal–maturity levels. The extracted kerogen samples were then synthetically matured. Variations in the composition and chemical–bonding state of carbon (C) present in kerogen at different levels of natural and synthetic thermal maturity were determined using X–ray photoelectron spectroscopy (XPS). The sessile drop method was used to measure the contact angle to quantify the wettability of kerogen. We then investigated the effects of thermal maturity and chemical composition/bonding of kerogen on its wettability.
Kerogen samples from two organic–rich mudrock formations (Formations A and B) were tested, and it was demonstrated experimentally that the wettability of kerogen varies with thermal maturity. Kerogen from Formation A at low thermal maturity formed a 44° air/water–contact angle and 110° air/oil–contact angle. However, at higher thermal maturities (heat treated at 650°C), the air/water–contact angle increased to 122°, and the oil droplet completely spreads on the kerogen sample. The results suggest that kerogen is oleophilic and hydrophobic at high thermal maturity and hydrophilic at low thermal maturity. The air/water–contact angles in kerogen samples were also recorded after the removal of bitumen generated during synthetic maturation of kerogen using chloroform. The air/water–contact angle was shown to increase from 44 to 90° and from 111 to 125° with an increase in thermal maturity in Formations A and B, respectively, in the absence of bitumen. Thus, kerogen becomes hydrophobic with increasing thermal maturity in both the presence and absence of bitumen. The outcomes of this study can potentially improve the formation evaluation of organic–rich mudrocks, in addition to improving our understanding of fluid–flow mechanisms in unconventional reservoirs.

Authors: Tsaritsentseva O. P. , Chekhovskaya M. N. 
Published: May 2019

The article features the phenomenon of career in modern social and economic conditions. The research studied career orientations of the personality, e.g. its definitions and role in career planning. The authors proved the relevance of studies in career orientation for social and professional development of women. The empirical research involved career orientations of women with inclination to a certain type of career in the context of their social and demographic characteristics. The authors analyzed such social and demographic characteristics as age, qualifications, work experience, marital and parental status, occupation, the sphere of employment, and income level. The research revealed specific features of women characterized by domination of a certain career orientation type, i.e. horizontal, vertical, or conditions-oriented. 18– 21-year-old unmarried childless women appeared to be focused on vertical career, competition, overcoming, difficult tasks, etc. 22–35- year-old mothers were more likely to reveal orientation to the horizontal type of career planning. Divorcees and widows tended to be conditions-oriented. The obtained data can be used in career guidance.

Published: May 2019

This paper presents an analytical review of scientific works devoted to one of the topical studies in cognitive and cultural linguistics, namely, to the concept of "money", which is included in the corpus of basic concepts of European civilization. Concepts as complex mental formations attract special attention of scientists studying the problem of language conceptualization of the person’s environmental world. Language units of different levels are studied in their correlation with the cognitive structure of the concept knowledge. The framework consists of systematization of the majority of existing scientific results of verbal representation, structuring of the concept of "money" in the context of Russian, English, German, and French. A comparative analysis of the ways and means of language representation of the concept "money" in Russian, English, German, and French sets the combination of versatile and specific features that embody the nature of the concept of "money" in these national languages. The obtained scientific findings represent the opportunities of embodiment of general cultural concept of "money" in national linguocultures. The practical value is determined by the fact that the obtained structured scientific data in the specified conceptual field can be used by scientists when developing linguoculturological dictionaries of basic concepts of European culture, as well as in the development of training courses with the dictionaries in question as content database.
A Medieval Repoussage Item from Pankrushikhinskiy District (Altai Krai)
Authors: Kazakov A. A. , Sitnikov S. M. 
Published: May 2019

The paper describes a bronze plaque, made in Perm animal style by method of one-side casting. It depicts a rampant winged bear with its paws on the shoulders of a standing man. Being an accidental finding, the plaque comes from the northern regions of the Altai Territory (the village of Vysokaya Griva, Pankrushikhinskiy District). The paper features its composition and plot, which has a complex semantic content. Following other researchers, the authors consider such products a metal reflection of the three-part world structure, characteristic for the peoples at a certain level of social development, and a myth about the origin of the people. A comparative analysis with both neighboring and quite remote areas made it possible to assume that there were different totem animals, ancestors of the major ethnic groups of different Finno-Ugrian peoples. Thus, a bird of prey was the most typical totem animal for the western territories representing a Finnish-speaking population that lived in the European part of Russia. The bird was both the ancestor and the guardian spirit of the ethnic group. A bear was the totem for the eastern territories of the Finno-Ugrian peoples living in Siberia, in the Asian Russia, that represented the Ugrian-Samoyedic population. It is evidenced by the absence of bears on the plaques with encoded myths about the origin of the kindred in Western European regions, and on the contrary, a practically complete absence of birds on similar plaques in the Asian regions. The finding is published for the first time.
Linguostylistic Means Expressing the Antithesis "Materialism − Moral Values" in John Braine’s Novel "Room at the Top" Exemplified by the Images of Susan Brown and Alice Aisgill
Authors: Kutsevich Yu. A. 
Published: May 2019

The study explores the linguostylistic means in John Braine’s novel "Room at the Top" (1957), which enabled the author to show the character’s inner conflict between his craving for wealth and power and his morals, or the conflict of social stereotypes about happiness and authenticity treated in this article as the real self of Joe Lampton. The true self makes itself evident through the contradictions that torture him in the course of his efforts to overcome social barriers and renounce moral values. The research objective was to analyze the interconnection between the expressive means in the novel and the sense they imply. The linguostylistic, motivic, contextual, and definitional analysis revealed that the antithesis "materialism – moral values" is presented in the opposition of the images of two women. Both play a significant role in the main character’s destiny. The antithesis is conveyed with the help of expressive means, such as contextual antonyms, evaluative vocabulary, syntactic parallelism, irony, climax, metaphor, etc. Susan Brown’s image embodies Joe Lampton’s material values, while that of Alice Aisgill personifies his moral values and the gradual loss of his authenticity.
The Naming Principles of Travel Agencies in Voronezh
Authors: Manukovskaya M. A. 
Published: May 2019

Naming in advertising has become one of the most ambitious areas of linguistics since it reflects dynamics of the lexical system of the language. It features proper names of goods, services, or business enterprises. An unusual proper name is efficient, noticeable and attractive for customers, it fulfills the advertising function. That is why it is necessary to identify the language principles which are taken into account when choosing proper names of a particular kind of a business enterprise, goods, or services. The present research was based on proper names of enterprises that offer tourism services in Voronezh. The naming units were obtained by direct observation, from the Internet, local newspapers, and magazines. The total number of collected examples included about 200 units. The study proved that language means for this type of nominations correspond with the nominative triad "seller / producer – product / service – buyer". In addition, some local territorial peculiarities were observed in the proper names of travel agencies.
Structure, Functions, and Level of Sexual Maturity in Female Undergraduates
Authors: Aizman N. I. 
Published: May 2019

The paper provides a brief analysis of the literature on the structure and functions of sexuality and the problems of its formation in undergraduate girls. The research featured 196 first and fifth year female students, age 17–22, that majored in pedagogical studies. The study involved a set of standardized test methods, e. g. R. Кеttell’s multifactorial personality method, Wiesbaden questionnaire, S. Bem’s Study of Personality Masculinity and Femininity, Ch. D. Spilberger and Yu. L. Khanin’s Evaluation of Reactive and Personal Anxiety, D. Russell and M. Ferguson’s Diagnostics of the Level of Subjective Feeling of Loneliness, methods of gender identity studies, M. Kuhn and T. McPartlend’s "Who am I?" test as modified by T. V. Rumyantseva, and the Scale of Basic Beliefs by R. Yanoff-Bulman. The statistical analysis of the results allowed the authors to build a structural and functional model of female sexuality, as well as to describe its components, functions, and informative characteristics. The factor analysis revealed that female sexuality includes five main components: family relations, cognitive, bodily, emotional and existential. Each of the components contributes to the overall structure and has a specific content and function. The authors developed criteria for diagnosing the levels of formation of female sexuality as low, medium and high. With age, the level of sexuality in all selected components increased, which might be associated with the presence of more experience in establishing intimate relationships and family orientation. Most respondents demonstrated diffuse gender identity accompanied by high androgyny as a variant of sex-role behavior. The study also revealed the effect of personal characteristics on the psychological content of the various components of sexuality. The obtained data determined the need for focused effort on the formation of femininity.

The Role of the Status of Selected Micronutrients in Shaping the Immune Function
Authors: Elmadfa Ibrahim , Meyer Alexa L. 
Published: May 2019

Objective:
This narrative review gives an overview on the essential role of adequate nutrition
to an optimally functioning immune defence. Micronutrients act as regulators of the immune response,
with the focus of this review on the immunomodulatory effects of the trace elements iron, zinc
and selenium, and the vitamins A, D, E, C, B6 and B12 and folic acid.

Results:
Iron deficiency especially impairs the Th1 cell-borne cellular immunity. T lymphocytes are
also most affected by a deficiency of zinc, needed for their maturation and the balance between the
different T cell subpopulations and acting as a redox signal in the regulation of many enzymes. Selenium
is also involved in redox reactions as the glutathione peroxidases and other redox enzymes are
selenoproteins. Selenium status has shown special effects on cellular immunity and resistance to viral
infections.

:
Vitamin A in the form of retinoic acid induces a humoral Th2 cell response via antigen-presenting cells
and is involved in maintaining intestinal immune defence and tolerance through its nuclear receptor
RAR and via kinase signalling cascades. Immune tolerance is particularly promoted by vitamin D acting
through dendritic cells to stimulate the differentiation of regulatory T cells. Vitamin E has antiinflammatory
effects and stimulates naïve T cells especially in the elderly. Besides its antioxidative
properties, vitamin C has effects on cell signalling and epigenetic regulation. The B vitamins are required
for cytotoxic cellular immunity and modulateT cell responses.

:
A diverse diet and regular exposure to sunlight are the best sources for a balanced nutrient
supply to maintain an optimal immune defence.
