Prácticas de gestión del conocimiento en organizaciones del tercer sector (ongs): caso de estudio
Authors: Aguilera Castro Adriana , Asprilla Castillo Vanessa
Published: December 2019

El presente trabajo tiene como objetivo verificar empíricamente las prácticas de gestión del conocimiento en una organización del tercer sector (ONG). Las Organizaciones no gubernamentales son cada vez más importantes, ya que logran suplir necesidades sociales insatisfechas; por tanto, el estudio de sus prácticas de gestión del conocimiento, es significativo para el apoyo al mejoramiento de su gestión. Este artículo aborda un estudio de caso; el enfoque de investigación es cualitativo, de tipo descriptivo y para la recolección de información se aplicaron entrevistas semi – estructuradas. El caso de estudio es la Fundación Carlos Portela, una organización reconocida en el Valle del Cauca (Colombia), por su labor de apoyo a los niños con cáncer y sus familias. Los resultados obtenidos en el estudio evidencian que la Fundación Carlos Portela desarrolla prácticas de adquisición, socialización, almacenamiento, distribución y uso del conocimiento, que en su mayoría, carecen de una estructura formalmente establecida. Esta situación se puede explicar principalmente porque no existe claridad de lo que significa gestionar el conocimiento y de los beneficios, oportunidades y potencialidades que representa esta actividad para el desarrollo de las organizaciones.
El marketing olfativo como posicionamiento de marcas
Authors: Grisales Castro Claudia Patricia
Published: December 2019

El objetivo de este estudio se basa en analizar la percepción que tienen los consumidores sobre el marketing sensorial olfativo, como estrategia utilizada para el posicionamiento de las marcas.

El sentido del olfato siempre ha sido un factor determinante en la toma de decisiones del ser humano, sin embargo, los estudios que existen sobre el proceso que vincula los aromas, el olfato y las marcas. Son descriptivos y de carácter interno por esta razón no pueden confirmar que un aroma estratégico, aplicado a una empresa o marca sea un factor de posicionamiento efectivo.

Algunas marcas ya utilizan el sentido del olfato como activador de relaciones, emociones y sentimientos con sus clientes, aprovechando que sentido del olfato no presenta saturación publicitaria, y tiene comunicación directa con la memoria, sin embargo, es una estrategia aislada que migra de otros países y que para la mayoría de empresas es un concepto nuevo como aplicación de marketing sensorial.

Se realizó una investigación cuantitativa de tipo exploratoria utilizando encuestas aplicadas a (120) consumidores, entre hombre y mujeres en edades 18 a 60 años con procesos de compra y consumo en el territorio colombiano.

Los hallazgos relacionan positivamente al consumidor y los aromas, también se puede evidenciar lo novedoso que es para el mercado el concepto de marketing olfativo, confirmando que algunos consumidores si conocen este tipo de estrategias, y la han experimentado en grandes marcas, como hoteles, restaurantes y sector vestuario.

Como conclusiones se puede evidenciar una disposición por parte de los consumidores en la implementación de estrategias sensoriales olfativas para las marcas. Convirtiéndose esto en una oportunidad de mercado interesante para las empresas, desarrolladoras y distribuidoras de marketing olfativo, ya que el consumidor en general está dispuesto a disfrutar de la estrategia sensorial olfativa.

Authors: ERTEKİN Hülya
Published: December 2019

Introduction: The aim of
this study was to evaluate the relationship between eating attitude, body
composition and disease severity in patients with anxiety disorders.Methods: This is
a cross-sectional case-control study conducted between January-March 2018 in
Clinic of Psychiatry of Çanakkale Onsekiz Mart University Medical Faculty of
Hospital. Beck depression scale (BDI), beck anxiety scale (BAI) and eating
attitude test (EAT) were applied to patients diagnosed as anxiety disorder
according to DSM-5 criteria and to healthy controls. Body compositions of all participants
were measured by Bioimpedance Analysis (BIA). Results: Twenty-five
patients with anxiety disorders and 25 healthy controls were included in the
study. The BDI and BAI scores of the participants measured the severity of
anxiety and depressive symptoms were statistically higher than the controls. (p
<0.001). There were statistically significant positive correlations between
BDI and BAI, EAT and BMI (p = 0.029, r = 0.436; p = 0.001, r =.630,
respectively). There was a statistically significant positive correlation
between EAT and BMI (p = 0.027, r = 0.441). There were no statistically
significant differences between two groups in terms of body fat ratios.

Conclusions: Our study shows that patients with anxiety disorders should be evaluated
for obesity and related factors and necessary recommendations should be made.
A critical analysis of the impact measurement in impact finance
Authors: Piras Luca
Published: December 2019

Academic literature on impact finance has not yet covered all aspects of the topic, nor has significantly contributed, so far, to solve several relevant problems arising from the field. Defining the metrics and measurement models suitable to assess impact is probably, among them, the most important one. Practitioners seem willing to exploit the potential value and, although useful heuristics and practical solutions have been found, no satisfactory and widely accepted valuation model is available. The present paper tries to summarize the state of the art, through the analysis of the available literature and tries to address some possible development in future research. The underlying idea is that the field is still very new, on one side, and extremely diverse in its manifestation, therefore no traditional theory fully applies to it. At the same time, the research on the topic still relays on practitioners’ effort, rather than on academia, a gap that ought to be filled. The paper concludes that Impact Finance and Investing are perhaps too narrow labels that limit the possibility to fully grasp the core of it and propose to widen up it by using “Positive Finance” as a more comprehensive one. Indeed, it has been found that academic empirical studies are so far very few and statistical findings far from being robust. The absence of accepted market models, prevent researchers from delivering a theoretical effective interpretation of the growing market.

Published: December 2019

An ability to instantly transmit and replicate information provides new means of identity construction and their impact on a person’s identity in the modern world. One of them is a social network as a form of interactive sociality transferred to virtual space. Social networks place a variety of entertainment content, provide access to information or means of further work with it at the users’ disposal, and affect the person’s perception of the world and himself. The paper explores some aspects of social networks functioning, which affects the modern person’s identity. It is observed that the process of self-assertion as a virtual person is not just a game for fun, but both a potential danger and a new space of creative self-realization in the information field, which can change significant aspects of the user's identity including ethical ones.
A Comparative Study of Political Process: Theoretical and Methodological Issues
Authors: ORDUKHANYAN Emil
Published: December 2019

The political process, as one of political science primary categories, is an important basis for political analysis. The political reality is created as a result of human activity, and it is connected with interrelated political interests' realization aiming to achieve predefined goals.

The article explores the theoretical and methodological foundations of political process based on the analysis of relevant works in this field of study. The institutional, behavioral, structural-functional approaches as well as conflict, discourse, and other methods of political process analysis are examined.  

Summing up the results of explored issues, we concluded that political process is a dynamic and nonlinear political phenomenon that can vary in time, taking into account the impact of various direct or indirect factors.

A comparative analysis of political process research approaches has shown that any particular approach can be efficient only in an appropriate situation and political time. In case of other circumstances' presence, the same approach cannot be applied efficiently to a precise political process. It is also necessary to consider the peculiarities of political process due to the political culture model, dominant in the given society.

Authors: BIGUNOVA Natalia , KOLEGAEVA Irina
Published: December 2019

The paper focuses on verbal and non-verbal characteristics of approval speech act in English literary discourse. Approval evaluation object have been identified including things, ideas, facts, traditions, weather conditions, events, pieces of news and other phenomena that become evaluated. It has been proved that approval evaluation objects never refer to the addressee's sphere of interests and that the approval recipient and the evaluation object of approval never overlap. The article also dwells on illocutionary aims pursued by approval speech act addressers and the perlocutionary effect of approval speech act. The main part of the paper considers lexical, morphological, syntactic, and stylistic means applied by the personages of literary fictional discourse to express approval of a certain object. Finally, non-verbal means manifesting approval have been identified. It has been found out that in literary fictional discourse it is the verbalized kinemes that specify the emotional state of the approval addresser and signal whether the approving utterance is sincere or not.

Science And Education In The Conditions Of Formation Of The Global World
Authors: URSUL Arkady
Published: December 2019

One of the main social transformations is that the formation of the global world is taking place and this world is reflected in science and education, and these last begin to form it. It is shown that to a large extent a global direction of research has already been formed, which includes globalistics, global scientific disciplines, globalization research, global evolutionism and a number of other areas of scientific research. Although this global cluster of scientific knowledge is most intensively developed only in the second half of the last century, its origins are found in the works of V. I. Vernadsky at the beginning of the same century. The global cluster of scientific knowledge is associated with the globalization of education and the formation of global education. The main integrative characteristics and features in the forms and content of these global evolutionary processes in education are revealed. It is shown that integrative tendencies connected with global-evolutionary changes of civilization and its interaction with nature are developed in education. It is noted that the globalization of education is focused mainly on the formal and organizational methods of integration of different systems and forms of education; the most important directions of this process are highlighted. And global education is characterized by qualitative and meaningful transformations of the educational process, the subject field of which is "filled" with universal-integrative knowledge obtained in the course of global studies. It is assumed that with the globalization of science and education begins a new global revolution in the scientific and educational space.
Schiff Bases and Triazolothiadiazines Derived from A Thiophene-Substituted 4-Amino-3-Mercapto-1,2,4-Triazole
Authors: Roman Gheorghe
Published: December 2019

4-Amino-5-(thiophen-2-ylmethyl)-2,4-dihydro-3H-1,2,4-triazole-3-thione was synthesized and converted into the corresponding Schiff bases using several aromatic aldehydes. Reaction of this aminotriazolethione with phenacyl bromides lead to triazolothiadiazines, which were subsequently reduced with NaBH4 to dihydrotriazolothiadiazines. The latter type of fused heterocycle has been also obtained directly by reacting one of the previously obtained Schiff base with phenacyl bromides. NMR analysis confirmed the structures of the synthesized compounds.

The obesity is one of the most common physiological disorders, also it is linked with a variety of circumstances like hypertension, dyslipidemia, T2DM, non-alcoholic fatty liver disease, and cardiovascular diseases. The aim of this study was to check the changes and compare serum omentin-1, lipid profile (TC, TG, VLDL-C, LDL-C, and HDL-C), trace elements (Mg, Zn, Cu, Fe) and insulin resistance between the prediabetic obese patients, healthy obese, and control subjects and assess the correlation between omentin-1, lipid profile, trace elements (Mg, Zn, Cu, Fe) levels and insulin resistance in prediabetic obese patients. Correlation analysis between omentin-1 levels with the biochemical parameters in the prediabetic obese patients with WC, body mass index, FBG, Insulin, HOMA-IR, HbA1c, TG, TC, LDL-C, VLDL-C, and copper was found to be negative; while significant positive correlation of omentin-1 with HDL-C, Mg, Zn, and Fe was noticed. Omentin-1 serum concentration level decrease and insulin resistance increased in prediabetic obese patients compared to healthy obese and control individuals. Omentin-1 inversely associated with obesity and insulin resistance, therefore can be used as a biomarker for obesity related metabolic disorders.

Published: December 2019

Streszczenie

Chłoniak rozlany z dużych komórek B (DLBCL) jest najczęstszym rodzajem chłoniaka u dorosłych i stanowi 30–40% wszystkich chłoniaków niehodgkinowskich. Większość pacjentów z DLBCL może być wyleczona za pomocą standardowego schematu immunochemioterapii zawierającego rytuksymab, cyklofosfamid, doksorubicynę, winkrystynę i prednizon (R-CHOP), jednak 30–40% pacjentów ma nawrót choroby lub jest opornych na leczenie pierwszego rzutu. Zrozumienie patogenezy DLBCL jest więc niezbędne do zidentyfikowania nowych potencjalnych celów terapeutycznych i opracowania nowych schematów leczenia w walce z tą chorobą. W przedstawionej pracy podsumowujemy obecną literaturę, skupiając się na zmianach genetycznych, w tym mutacjach somatycznych, zmianach liczby kopii i translokacjach chromosomowych zidentyfikowanych w DLBCL.

Streszczenie

Talasemia alfa to niedokrwistość wynikająca z mutacji w genach kodujących alfa-globinę lub w elementach regulatorowych klastra alfa-globiny. Zespół hemoglobiny Barta to najcięższa postać tej niedokrwistości, spowodowana defektem genetycznym prowadzącym do całkowitego braku syntezy alfa-globiny, najczęściej wynikającym z delecji obu kopii genów z każdego allelu. U chorych nie są syntetyzowane dwie dominujące hemoglobiny niezbędne dla prawidłowej ontogenezy – HbF w okresie płodowym oraz postnatalnie HbA. Hemoglobiną dominującą jest hemoglobina Barta, składająca się wyłącznie z łańcuchów gamma-globiny. Choroba ujawnia się w okresie prenatalnym w postaci niedokrwistości oraz obrzęku płodu. Przypadek tej postaci talasemii alfa został zdiagnozowany i był skutecznie leczony prenatalnie w jednym z ośrodków w Polsce. W pracy przedstawiono jego opis kliniczny oraz zaprezentowano wyniki badań biochemicznych i molekularnych.

Authors: Karpavičienė Birutė , Mlečkaitė Giedrė Elzbieta
Published: December 2019

The morphological variation and population structure were studied in seven populations of Polygonatum multiflorum and 19 populations of P. odoratum. The mean number of flowers per shoot and per inflorescence as well as inflorescence number per shoot in both species correlated negatively with total tree and shrub canopy cover, while the mean number of flowers per inflorescence in P. odoratum correlated positively with the soil pH. The shoot density and life stage composition in P. odoratum populations depended on total tree and shrub canopy cover, which negatively correlated with the density of generative shoots in populations of both species. The results of this study revealed the crucial effect of light availability expressed via total tree and shrub canopy cover in the habitats of Polygonatum species to their flowering intensity and population structure.

Authors: Kovtoniuk Anna
Published: December 2019

The aim of our work was to analyse synanthropic fraction of spontaneous flora of gardens and parks in the Middle Pobuzhzhia Region of Ukraine and to reveal the features of synanthropisation. The landscapes of gardens and parks in the Region include botanical gardens, arboretums and monuments of landscape art. A total of 15 objects were studied. The floras of parks were estimated by proportion of different groups (origin, naturalisation degree, time and ways of introduction) of synanthropic species. The synanthropic fraction of spontaneous flora was calculated using the indices of synanthropisation, apophytisation, anthropophytisation, archeophytisation, kenophytisation and modernisation. These indices were specified for each park and for the Middle Pobuzhzhia Region in general. The obtained data were compared to each other and to the analogous urban floras from different zones of Ukraine. It was revealed that the apophytisation processes were dominated by the processes of adventisation in most of the parks. The proportion of the synanthropic fraction of spontaneous flora of the Middle Pobuzhzhia Region was significantly lower compared to urban floras of some cities of Ukraine, and despite a considerable anthropogenic pressure retained some features of natural flora.

Authors: Krupińska Izabela , Płuciennik-Koropczuk Ewelina , Gągała Sylwia
Published: December 2019

Aluminium is one of the environmental factors that may have an impact on Alzheimer’s and Parkinson’s disease. Some epidemiological studies show a relationship between the concentration of aluminium in drinking water and the incidence of Alzheimer’s disease. The article presents and discusses the results of research on the effect of the type and dose of non-prehydrolyzed aluminium coagulants on the concentration of residual aluminium in water intended for human consumption. Aluminium sulphate (VI) and sodium aluminate were tested as coagulants. Analysis of the obtained test results showed that lower concentrations of residual aluminium were found after coagulation with aluminium sulphate (VI), which is hydrolyzed acidally, lowering the pH of the water in the range of 7.47 to 7.12 providing good conditions for the formation of Al(OH)3. A less useful coagulant due to the concentration of residual aluminium was sodium aluminate, which undergoes basic hydrolysis creating conditions for the transition of Al(OH)3 into soluble Al(OH)4−.

Analysis of physical and chemical properties of drinking water after the modernization of the system showed the effectiveness of the water purification processes used and the correct selection of the technological line. The obtained water quality parameters were in accordance with the Regulation of the Minister of Health on the quality of water intended for human consumption (Journal of Laws of 2017, item 2294).
Haemophilus influenzae and Haemophilus parainfluenzae occurrence in the ear effusion in pediatric patients prone to recurrent respiratory tract infections (RRTI) and with otitis media with effusion (OME)
Authors: Kosikowska Urszula , Chwiejczak Edyta , Niedzielski Artur , Andrzejczuk Sylwia , Malm Anna
Published: December 2019

Introduction.
Haemophilus influenzae and Haemophilus parainfluenzae are known as human-restricted respiratory microbiota representatives. The aim of the present paper was to assay haemophili prevalence in middle ear effusion specimens in pediatric patients with otitis media with effusion (OME).

Methods. A total of 86 ear effusion specimens (from the left and right ear independently) were collected from 43 pediatric patients with OME. For comparison, 58 nasopharyngeal specimens were taken from 58 pediatric patients prone to recurrent respiratory tract infections (RRTI). Isolation and identification of haemophili biotypes and antimicrobial susceptibility was accomplished by standard microbiological methods. The cell surface hydrophobicity (CSH) of isolates was assayed by the method of aggregation in ammonium sulfate (SAT).

Results. Haemophili were isolated in 25.6% (11/43) of all OME patients: in 5/43 (11.6%)– H. influenzae (biotypes II, III), in 5/43 (11.6%) – H. parainfluenzae, in 1/43 (2.3%) – both species were found. Haemophili-positive nasopharyngeal specimen was found in 27/58 (46.6%) RRTI patients: in 19/58 (32.8%) – H. influenzae, in 8/58 (13.8%) – H. parainfluenzae. About 90% of all haemophili isolates were characterised by extreme to strong CSH. Antimicrobial resistance occurred mainly among H. parainfluenzae (80%) and to a much lower percentage among H. influenzae (33.3%) isolates. The obtained data suggest that both H. influenzae and H. parainfluenzae can be involved in pathology of OME in pediatric patients. The high cell surface hydrophobicity can affect on the haemophili prevalence and ear colonization, and induces predisposition to the presence of these bacteria as a biofilm that serves as a virulence factor with great importance for the survival of these opportunistic bacteria and their persistence in the ear environment.

Published: December 2019

Various laboratory parameters are commonly used to assess the efficacy of biological treatment (BT). The aim of our study was to assess the correlation between platelet (PLT) indices: (mean platelet volume (MPV), plateletcrit (PCT), platelet distribution width (PDW)), C-reactive protein (CRP) and endoscopic picture in the course of infliximab induction regimen in ulcerative colitis (UC) patients. The study enrolled 46 patients with UC – 32 men and 16 women. They were administered infliximab (standard induction therapy). Laboratory tests (CRP and PLT indices) and colonoscopy were performed in all patients during the induction regimen – at 0, 2, and 6 weeks and in follow-up six weeks after the completion of induction therapy. The study revealed a statistically significant decrease in CRP and PLT, and an increase in MPV, together with improvement of endoscopic picture (p <0.001) (MAYO score, MAYO endoscopic subscore) in all patients. PCT and PDW values remained in normal ranges before BT and after the finish of the induction regimen. PCT correlated positively with CRP before the introduction of BT (p = 0.018). In addition, positive correlations between PCT and PLT count were noticed before infliximab induction regimen and in follow-up after the finished of therapy (p <0.001). Additionally, a negative correlation between PLT count and MPV prior to the first dose of infliximab was observed (p=0.032). Our data suggest that PLT indices could be useful biomarkers for determining active UC and for assessing the efficacy of BT. From what we know, this is the first survey devoted to PLT parameters in Polish patients with UC.

Subject and purpose of work: The aim of the conducted research and analyzes was the attempt to assess the impact of selected factors over tourist activity of people with disabilities and factors related to the immediate environment of people with disabilities

Materials and methods: A total of 5 000 respondents were subjected to the quantitative research. Participants of the research were adults with legally recognized disabilities. In the research, there was used the method of a diagnostic survey.

Results: Tourist activity of disabled people living in rural areas in Poland concerns only about 50% of respondents. Leaving the place of permanent residence in a free time is the most often declared by young and middle-aged people with higher, secondary and post-secondary education, professionally active, married people with mental and sensory disabilities.

Conclusions: Factors stimulating participation in tourism are the level of education and professional activity of respondents. In the assessment of respondents the important factor is also a general family situation.
The Darling Men of Sean O’Casey’s Juno and the Paycock: An Early Postmodern Representation of Masculinity
Authors: Malkawi Sohaib
Published: December 2019

This article examines how Sean O’Casey’s Juno and the Paycock, written in 1924, anticipated the postmodern conception of gender, or more accurately, the postmodern deconstruction of gender as merely repetitive patterns of behavior. The focus is on how the play dramatizes the Foucauldian notion of the death of man in the neurotic and irresponsible behavior of the male characters. Taking the psychological vertical approach in the analysis, the article adds to the scholarly work that has been written about the play, which mostly focused on its sociopolitical and religious aspects. The analysis this article sets forth shows how O’Casey’s representation (or perhaps mal-representation) of male characters was symptomatic of the cultural upsurge that later came to be known as postmodernism. In so doing, the article makes a curious link between O’Casey’s representation of neurotic men and the more recent inception of postmodernism and its deconstruction of gender. This link, in other words, is between neurosis and deconstruction, between psychological disturbances and the much-celebrated postmodern theory that came later. Thus, the article concludes with the peculiar question of how much of postmodern thought was, albeit unconsciously, predicated upon psychological degeneration, especially when it comes to its deconstruction of gender dynamics.
‘The Cake is (Not) a Lie:’ Intertextuality as a Form of Play in Digital Games
Authors: Melnic Diana , Melnic Vlad
Published: December 2019

Since Julia Kristeva’s first use of the term in the late 20th century, intertextuality has given rise to one of the literary theories most frequently applied in the interpretation of texts across different media, from literature to art and film. In what concerns the study of digital games, however, the concept has received little attention, in spite of the fact that the new medium offers a more than fertile ground for its investigation. The aim of the present essay, therefore, is to propose that digital games can be and, indeed, are intertextual in at least two ways. First, we argue, games deliberately refer to other games, which may or may not be a part of the same series. Secondly, they connect with texts from other media and specifically with literary texts. In both cases, the intertextual link can be a sign of tribute, a critical comment, or a means of self-reflection. Ultimately, however, these links are a form of aesthetic play that reveals new similarities between digital games and traditional media for artistic expression.

Due to the remarkable health benefits of celery (Apium graveolens), its consumption has increased over time. A partial substitution of NO3
− with NH4
+ is recommended to limit the accumulation of NO3
− in leafy vegetables. Hence, a factorial experiment with two factors, consisting of six treatments as combinations of three NH4:NO3 ratios (0:100, 20:80 and 40:60) in nutrient solutions and two harvesting times (in the morning and in the evening), was conducted on celery plants in a soilless culture system. The results showed that 100% NO3 as a sole N source significantly increased plant height, leaf number, chlorophyll, fresh weight, N, K, Ca, Mg, Fe, Mn, Zn, protein, dietary fibre, soluble sugars, nitrate, vitamin C, α-carotene, β-carotene and lutein of celery plants compared to either 80 or 60% NO3. However, this increase was not significant compared to 20% NH4:80% NO3 in terms of leaf number, fresh yield, N, Mg, Mn, protein, soluble sugars, vitamin C and α-carotene. Harvesting in the evening significantly increased K, Mg, Fe, soluble sugars, α-carotene and β-carotene, and lowered the nitrate level in celery plants. In conclusion, partial replacement of 20% NO3-N with 20% NH4-N and evening harvesting are recommended for a greater fresh yield, higher quality, and lower nitrate level.

Published: December 2019

The Actinidia genus includes a number of commercial fruit species with a wide range of countries of origin. Some species such as A. arguta or A. kolomikta are characterized by a high level of resistance to frost. The aim of this study was to compare the fruit of selected cultivars of kiwiberry. In the kiwiberry fruit, sucrose was the predominant type of sugar. Citric acid was dominant in all samples; it was most represented in the pulp of kiwiberry seedlings and in the skin of kiwiberry ‘Issai’. Kiwiberry fruits feature a higher ascorbic acid content in the skin in comparison with the commercial A. chinensis cultivars. Antioxidant activity of kiwiberry fruit skin was up to 18 times higher than that of the pulp. In view of the kiwiberry fruit having no hair, it is possible to eat the whole fruit, including the skin containing substances beneficial to health.
Crucial Directions of the Development of Continuing Education in Russia. Aspects of Quality
Authors: Viktorovna Martynenko Elena , Petrovich Parkhitko Nickolay
Published: December 2019

The development of the lifelong education system is one of the most important areas of educational activity, which implies the continuity of processes in the systems of preschool, general secondary, primary, secondary, higher, postgraduate and additional professional education. The effectiveness and the possibility of educational activities are determined by the interconnections between the various stages of the innovation cycle, producers and consumers of services; firms, market, government and other social partners. Continuing education can be seen as part of a lifelong learning concept. Continuing education is not just a pedagogical system, characterized by certain structural features, functional relationships and teaching technologies, but also a specific component of the whole society. It becomes continuous, connected with life, and not just final, prescribed to a person during his studies at school, secondary school or university. The development of the lifelong education system allows creating all the necessary conditions to ensure the response of the education system to the dynamically changing needs of the individual, society, and the economy. In addition, many scientists note that the continuing education system plays an important role in the formation of personnel for the innovative development of Russian regions. The development of the lifelong education system is aimed at supporting the competent development of the individual, at implementing the concept of developing education. A competency-based approach to education creates all the necessary conditions for the diverse development of the individual, the formation of competencies and personal qualities that allow effective action in various life situations. The concept of lifelong education is based on the principles of continuity, flexibility, fast dynamics associated with changing needs in the labor market, for the implementation of education “not FOR life, but THROUGH life”. The article is devoted to the problem of implementation of continuing education in Russia and its impact on the quality of education in our country.
Globalisation, migration flows and sustainability
Authors: Varani Nicoletta , Bernardini Enrico
Published: December 2019

The mobility of people is an important theme of geographical research because immigrant currents profoundly transform regional models, mainly urban areas, configuring themselves as a factor of social destabilization, as they change the composition of the population, triggering processes of mutual cultural contamination that are projected on the territory, differentiating it from its geographical surroundings. The contribution, starting from a look at international migration, intends to analyze different aspects related to the phenomenon of mobility such as globalization, sustainability and the role of International Cooperation in the light of the objectives of Agenda 2030 for sustainable development, challenges that concern not only the present, but especially the future.

In this paper we assess the irrigation water use in the Danube Basin, highlight its complexity, identify future challenges and show the relevance for a basin-wide integrative irrigation management plan as part of a more holistic and coherent resource policy. In this sense, we base our integrative regional assessments of the water-food-energy nexus on insights from an extensive review and scientific synthesis of the Danube Basin and region, experimental field studies on irrigation and agricultural water consumption, current irrigation related policies and strategies in most of the Danube countries, and regulatory frameworks on resources at European Union level. We show that a basin-wide integrative approach to water use calls for the evaluation of resource use trade-offs, resonates with the need for transdisciplinary research in addressing nexus challenges and supports integrative resource management policies within which irrigation water use represents an inherent part. In this respect, we propose a transdisciplinary research framework on sustainable irrigation water use in the Danube Basin. The findings were summarized into four interconnected problem areas in the Danube Basin, which directly or indirectly relate to irrigation strategies and resource policies: prospective water scarcity and Danube water connectedness, agricultural droughts, present and future level of potential yields, and science based proactive decision-making.
Nuclear reaction applied to fluorine depth profiles in human dental tissues
Authors: Torrisi Lorenzo
Published: December 2019

The nuclear reaction 19F(p, αγ)16O is presented as a valid method to measure the fluorine content in the first superficial layers of teeth. The analysis is performed in-vitro in extracted teeth, both healthy, fluorotic and decayed. It is performed irradiating the tooth with an energetic proton beam and analyzing the emitted high energy alpha particles. The quantitative analysis is performed comparing results with that of a standard sample at a known concentration. The depth profile of fluorine has a maximum content in the first superficial layers. The average concentrations in healthy enamel are of the order of 2 mg/g; it is of about 10 mg/g in fluorotic teeth, and below 0.1 mg/g in decayed teeth. The concentration in the dentine is about 50% lower than in the enamel and the concentrations decrease going from incisors to premolar and to molar teeth. Many results and a literature comparison are presented and discussed.
