Published: December 2019

The research was conducted at the intersection of such subject fields as sociology of youth, sociology of education and sociology of communication. The paper analyzes a new generation of young peo-ple born at the very turn of the century and socializ-ing in the context of digitalization and mediatization of a society where significant socio-economic and sociocultural changes took place, in particular, man-ifested in the growing tendency of a contradictory attitude towards higher education. The main aim of the research is to identify the most prominent sub-jects of communicative impact on development of educational strategies of modern young people in Russia in the period when they complete their high school education, as well as bachelor’s or master’s degree programs. As a result of an empirical research there are identified main communicative sources that influence educational strategies both during an extended period of their development and at a final stage of constructing such strategies for a short term. The study also defines a diverse role of parents in the development and choice of educa-tional strategies of modern Russian young people at the end of a consecutive stage of their education. The data obtained concretize a socio-communicative portrait of the new generation of Russian youth in the conditions of digitalization and mediatization of the society, the growth of uncer-tainty and risk.

Authors: Martín-González Nerian , Martinez-Merino Nagore , Martos-García Daniel , Usabiaga-Arruabarrena Oidui
Published: December 2019

Este artículo pretende ayudar a entender la forma en que las presas se relacionan con la droga en prisión y cómo la práctica de actividad física juega un importante papel a la hora de prevenir el consumo. El estudio se basa en cinco entrevistas a distintas presas y ex–presas y en un trabajo de campo etnográfico. Los resultados se presentan como una historia de vida recreada de forma narrativa. Así, el relato evocador profundiza, entre otros aspectos, en el modo en que la actividad físico-deportiva se convierte en un proyecto de vida alejado de la drogodependencia.
Biopoder y Departamento de Cultura Física (Universidad Nacional de La Plata, 1929-1946)
Authors: Kopelovich Pablo
Published: December 2019

Se analiza el accionar del Departamento de Cultura Física de la Universidad Nacional de La Plata (Buenos Aires, Argentina), desde su creación en 1929 hasta su disolución en 1946, a partir del concepto de biopoder de Michel Foucault. Esta dependencia se encargaba del gobierno de los cuerpos infantiles y jóvenes de la mencionada casa de estudios, enseñanza de Educación Física para los alumnos de la escuela primaria “Joaquín V. González” y el Colegio Nacional, y para las alumnas del Colegio Secundario de Señoritas. Así, se identifican elementos que remiten tanto a las disciplinas como a la biopolítica, a la vez que se hace referencia al elemento que se halla en la intersección de esas dos tecnologías de poder: la sexualidad. Se lleva a cabo, entonces, un estudio de caso, en el marco de una metodología cualitativa, y se utiliza el análisis de documentos como técnica de investigación.
Berbagi pengetahuan sebagai pembelajaran organisasi di Perpustakaan Nasional Republik Indonesia

Published: December 2019

Knowledge sharing process is an interactive communication activity between individuals, aimed at increasing each individual’s competence. An organization shares knowledge as an organizational learning medium so the organization can continue to grow and update information owned by individuals. This study discussed the knowledge sharing process in organizational learning at the National Library of the Republic of Indonesia (PERPUSNAS). As the parent library institution in Indonesia, PERPUSNAS has a vital role in improving the quality of librarians, through organizational learning in the form of knowledge sharing activities. This research was conducted to determine the process of applying knowledge sharing, which included aspects of knowledge sharing behavior and the benefits of its application in organizational learning in PERPUSNAS Preservation and Conservation Sub-Division. This qualitative research used a case study approach. Data were collected through observation, interviews, literature study, and documentation. Based on study results, the knowledge sharing process in organizational learning at PERPUSNAS consisted of four aspects, including aspects of subjective norms, attitudes, aspects of behavioral control, and social networking. Librarians in the subjective norm, always directly accepted new policies from superiors. Regarding attitude, librarians succeeded in bringing the organizational direction in a better and non-monotonous direction. Regarding the behavioral control aspect, PERPUSNAS maximized staff potentials by giving the freedom to work outside the sub-field. Also, social networking issues added to the librarian’s convenience when sharing knowledge through social media groups, such as WhatsApp. Knowledge sharing activities at PERPUSNAS become a means to improve individual competencies to become better human resources.
Dispositivo publicitario y desarrollistas urbanos
Authors: Castro Julián Francisco , Vaccaro Natalia Desirée
Published: December 2019

En este artículo, proponemos un abordaje sociosemiótico de las producciones de sentido del sector autodenominados “Desarrollistas Urbanos” de la ciudad de Córdoba. En un contexto de ocupación clasista del espacio, favorecido por las nuevas formas de intervención en la ciudad, el  sector privado se convierte en un actor de peso en las disputas en torno a la producción de ciudad y los modos deseables de habitarla. Proponemos leer estos discursos en el marco de una política urbana, propia de las sociedades contemporáneas, orientada hacia la producción de experiencias.

Manantiales de Edisur, ubicado en la zona sudoeste de la ciudad, con una extensión de 10 km2 y variada oferta de estilos habitacionales, es un caso paradigmático. Nos interesa reconstruir algunos elementos del dispositivo publicitario (Boito, Espoz y Michelazzo, 2015) que el Grupo Edisur despliega para promocionar su proyecto. Nuestro estudio discurrirá sobre un corpus construido en torno a las plataformas virtuales, específicamente, el segmento “Manantiales” de su página web, su ​landing page ​y la revista digital “Manantiales”. Pretendemos que el análisis nos permita evidenciar el sistema de evaluación social imperante (Medvedev y Bajtín, 1993) sobre lo que puede/debe o no hacerse en el espacio de la ciudad y quiénes pueden/deben hacerlo y por qué.

Published: December 2019

En este artículo presento de forma parcial los resultados de mi investigación de tesis doctoral, que se ha centrado en explorar el papel de las tecnologías de la información y comunicación en los procesos de conformación identitarios y de inserción de las comunidades de migrantes en sus territorios de acogida a partir del caso de los migrantes mexicanos en Estados Unidos. Para ello realizo un mapeo de los grupos y páginas en Facebook correspondientes a la comunidad mexicana en Nueva York y Los Ángeles. Dos ciudades con trayectorias, patrones de asentamiento y estructuras organizacionales muy diferentes. En este artículo exploro la relación entre presencia virtual y redes sociales migratorias, y de qué forma son utilizadas las TIC en el proceso de adaptación y llegada a la sociedad de acogida por parte de las comunidades migrantes.  Trato de conocer a través de un análisis comparativo tanto el grado de inclusión y participación de esas comunidades en la Sociedad de la Información y si las TIC suponen una actualización eficaz  respeto a las funciones tradicionales de protección, inclusión y cohesión grupal desempeñadas por los tradicionales clubes de migrantes o por el contrario su utilización supone una respuesta a dinámicas, contextos y necesidades diferentes.
Sistema alimentario carnista y crisis climática
Authors: Navarro Alexandra , Andreatta María Marta
Published: December 2019

El sistema alimentario actual, con su énfasis en el consumo de carne y otros productos de origen animal, es parte fundamental de la crisis ambiental que está atravesando el planeta. Este sistema, que se sostiene a partir de la producción ganadera y la industria cárnica, no sólo es profundamente cruel con los animales no humanos, sino que fomenta una producción alimentaria a la cual la humanidad está teniendo acceso de manera desigual, situación que empeorará en el mediano plazo, según las últimas estimaciones, en tanto supone una rápida degradación de los suelos, el aire, el agua potable y la pérdida de la biodiversidad. Este trabajo realiza un abordaje del problema, cartografiando sus diversas aristas y proponiendo las dietas veg(etari)anas como un aporte relevante y factible a la solución del escenario analizado.
Interpretación de transformaciones lineales en el plano utilizando GeoGebra
Authors: Gallo Humberto G. , Verón Claudio , Herrera Carlos Gabriel
Published: December 2019

En el estudio de conceptos de Algebra Lineal, algunas de las dificultades cognitivas que se observan en los alumnos son derivadas de la falta de articulación de diferentes representaciones de un objeto matemático, especialmente entre el registro simbólico y su correspondiente correlación geométrica en los espacios vectoriales (R2.+.R,*) o (R3.+.R.*), prevaleciendo, en consecuencia, procedimientos de carácter algorítmicos en desmedro de lo conceptual. Fundados en la teoría de la Visualización Matemática, se propone a tales efectos el uso de software GeoGebra como herramienta didáctica en el proceso de aprendizaje de contenidos de algebra Lineal, en caso particular de transformaciones lineales. El carácter dinámico de este aplicativo permite la interpretación geométrica de la transformación, y de conceptos asociados como su núcleo e imagen, a partir de su respectiva matriz asociada, se pretende además que descubran las relaciones entre la singularidad de la matriz, con las dimensiones del núcleo e imagen de la transformación lineal.
Transteoretical Approaches on Domestic Violence
Authors: Popa-Nedelcu Radu , Siserman Coste , Domnariu Carmen Daniela
Published: December 2019

Domestic violence is a widespread public health problem. Domestic violence does not just manifest itself physically, it can take different forms, from verbal aggression to insults of psychological, emotional, sexual, material deprivation or simply negligence. All these affect the victim in many ways. Thus, the professionals in medical, legal sciences, but also the state authorities with responsibilities in social protection and assistance must know the phenomenon very well and find the best ways to fight it. No institution will be able to achieve this objective by working individually, but only an efficient cooperation of all these factors can contribute to limiting the negative effects and the state of vulnerability, but also to provide information and support to the victims.

Published: December 2019

The main objective was to identify pregnancy risk factors arising from the behaviour and lifestyle of Mureş county women during pregnancy. The postpartum women monitored in this study were from Mureş county and were interviewed by applying a questionnaire during the period they were in the hospital for postnatal care immediately after birth. The questions aimed at identifying prenatal risk factors and the unhealthy behaviour of women before and during pregnancy, referring to the socio-economic and cultural status (low family income or unemployment, less than high school studies, rural background and marital status), obesity during pregnancy, alcohol consumption, coffee consumption, no physical activity. We identified, among the three major ethnicities in Mureş county (Romanian, Hungarian, Roma), the behaviour and lifestyle components with risk in pregnancy and after comparing profiles of these groups we identified the Roma ethnicity as being at the highest perinatal risk.

At this moment, geriatric dentistry represents a very well-defined discipline, which deals with the dental treatments in the elderly patients, more precisely the patients over 60 years old. Unfortunately, in Romania, geriatric dentistry is currently very superficiality treated, this being rather an optional study discipline in the curricula of Dental Medicine Faculties. Therefore, in this material we have tried to explain through solid arguments the importance of geriatric dentistry in the basic training of dentists, dental and dental prophylaxis nurses, as well as dental technicians.
Setting up an electroconvulsive therapy (ECT) Department in the Psychiatric Hospital “Dr. GH. Preda” of Sibiu
Authors: Bacilă Ciprian , Anghel Claudia
Published: December 2019

Electroconvulsive therapy has a long history, with periods of approval and of contradiction. The electroconvulsive therapy department in our hospital has a long tradition: it was initiated in 1940 and used for a period of five decades, after which it was abandoned due to several reasons. Starting with the year 2019, it was desired to create a new ECT department that corresponds to the new modern requirements of ECT’s application (under anesthesia). This department was built according to the Portuguese model of the ECT department with the main purpose to increase the accessibility of psychiatric patients to this type of treatment, to decrease the number of hospitalization days for the patients with severe psychiatric disorders and also to train new professionals in this field. Although many clinical studies have shown their effectiveness in treating psychiatric pathology due to preconception and stigmatization, nowadays this treatment is still seen with great reluctance.

Authors: Iancu Gabriela Mariana , Mahu Lilia , Rotaru Maria
Published: December 2019

Lichen planus is an autoimmune, itching disorder that involves T lymphocytes, which may interest the skin, mucous membranes and exoskeletons. The presence of lichen manifestations both at the skin, mucous membranes and at the level of the skin attachments (hair and nails) is rarely mentioned in the literature. Although lichen planus may have a self-limiting evolution, early treatment is important in shortening the evolution of the disease and in controlling the symptoms. The therapeutic effects of retinoids (immunomodulatory, anti-inflammatory, anti-proliferative effects) make them an appropriate choice in the treatment of lichen with (cutaneous-mucosal, nail and planopilaris lesions. We will present the cases of 2 patients with muco-cutaneous, nails and scalp disorder due to lichen planus, and the time of presentation to the doctor made the difference between the complete remission of the disease and the evolution towards severe, extended, definitive alopecia in the scalp and genital lichen sclerosus.

Published: December 2019

Hysteroscopy is a surgical procedure that allows a direct view of the uterine cavity and the tubular ostium. This procedure can be performed for both diagnostic and curative purposes. Hysteroscopy have several indications including the evaluation of abnormal uterine bleeding, infertility or intrauterine tumours identified by ultrasound. The purpose of this paper is to evaluate the correlation between the diagnosis at admission and the intraoperative aspect of the uterine cavity following the hysteroscopic evaluation. We evaluated the patients admitted to the Obstetrics and Gynaecology Clinic of the Sibiu County Emergency Clinical Hospital during 1.01.2019-07.06.2019 who had the following criteria: age between 15-64 years, patients with infertility, patients who had vaginal bleeding or intrauterine tumours or structure identified by ultrasound.

Authors: Bitea Cornel Ioan , Bălţat Georgiana , Maniţiu Ioan
Published: December 2019

Mechanical stress due to flexion-extension in the femoropopliteal space may cause stent failure via stent fracture and thrombosis. Wire-Interwoven self-expanding Nitinol Stents design partially mimics the reticular structure of native vessels, emphasizing radial strength, flexibility and kink resistance; these stent features can offer more chances for short and long term patency. We have evaluated 5 patients with peripheral artery disease with significant superficial femoral artery or proximal popliteal artery lesions. All patients underwent endovascular therapy with Wire-Interwoven self-expanding Nitinol Stents, with primary focus on stent patency at follow-up visits (1, 6, 12 months). The endovascular initial success was achieved in all 5 patients. Stent patency at 1-year follow-up was achieved in 3 patients (60%). 2 patients (40%) had stent thrombosis within 30 days after procedure secondary to arterial dissection at distal stent extremity and self-withdrawal dual antiplatelet therapy; subsequently target lesion revascularization with endovascular therapy and ilio-femoral bypass was performed.
Lung Ultrasonography – A Paraclinical Investigation Promoter in Community-Acquired Pneumonia Diagnosis in Children
Authors: Grădinariu Gabriel , Dobrotă Luminiţa , Neamţu Mihai-Leonida
Published: December 2019

Lung ultrasonography is an excellent alternative to chest radiography, with better sensitivity, specificity, positive and negative predictive values and, finally, with better accuracy. The lung ultrasonography is proven to be useful in trying to reduce the request of chest radiography. In the opinion of most specialists, lung ultrasonography is recommended to be a valuable tool for the diagnosis of community-acquired pneumonia in children. Considering the fact that clinical examination remains essential because it suspects the diagnosis, the evolution does not require radiologic follow-up, also the pathologic findings at the clinical examination may change over the course of a day, the possibility of the clinician to maintain the objectivity is essential. For this goal to be possible, it would be ideal that the clinician himself performs the ultrasonography (in real-time).
Intra-Abdominal Pressure, a Prognostic Marker in the Evolution of Acute Pancreatitis
Authors: Bereanu Alina Simona , Vintilă Bogdan , Sava Mihai
Published: December 2019

In acute pancreatitis some prognostic scores have been suggested, based on clinical, laboratory and radiological criteria. The most popular are: Ranson score, APACHE II score and CT severity index (CTSI). The trend is to find a prognostic marker that is easy to use, cheap, and reproductible. Recently, the increase of the intra-abdominal pressure (IAP) has drawn attention. Material and Methods: From January 2012 to April 2014, a group of 64 patients, admitted to the Clinical Department of Anaesthesia and Intensive Care and the Surgical Departments of the SCJU Sibiu, with the diagnosis of acute pancreatitis, were included in this observational prospective study. The cut-off values, the specificity and sensitivity of the prognostic scores were calculated using the receiver operating characteristics (ROC) analysis curves. Results: At a cut-off value of 12 mm Hg IAP max has a sensitivity of 0,75, similar to Ranson score at 48 h (0.72 at a cut-off value 3) and CTSI (0,73 at a cut-off value 4). Better results are just for APACHE II score at 24 h (0,88 at a cut-off value 8). IAP max has a specificity of 0,88, simillary to CTSI (0,83) and APACHE II score (0,82). Conclusions: In our study maximum IAP could be correlated with prognostic markers for severe evolution in acute pancreatitis.
Management and Prevention of Complications of Guided Bone Regeneration
Authors: Țânțar Cristian Alexandru
Published: December 2019

Guided bone regeneration using titanium-reinforced expanded teflon non-absorbable membranes (e-PTFE) has proven, through rigorous studies on many occasions, that it is a safe and predictable method to achieve bone growth at mandible and maxilla level, both vertically and horizontally. However, the technique itself is one that requires special operative skills and is not without postoperative complications. The purpose of this paper is to review most of these postoperative complications, their management and the key operative elements that help preventing them. Complications are presented both from the perspective of the meta-analysis performed from the present literature and from the point of view of the author’s personal experience, personal casuistry being presented. This paper will discuss all this starting with the complications without negative impact on the bone regeneration such as, late exposure of the membrane and ending with the most serious ones, such as the suppuration of the augmented anatomical regions. All of these can be avoided or minimized by using a correct operating technique. In addition, once installed, we can minimize the negative effects on bone regeneration by a proper management applied at the right time.

Assessing the Effects of Corporate Taxation on the Investment Policy of Manufacturing Firms in Nigeria
Authors: Akinleye Gideon T. , Olarewaju Odunayo M. , Fajuyagbe Samson B.
Published: December 2019

Research Background: The complexities of taxes in business have a tendency of endangering investment decisions at every point in time, if such complexities are not strategically managed.

Purpose: This study therefore assesses the effect of corporate taxation on the investment policy of quoted manufacturing firms in Nigeria.

Research Methodology: Secondary data sourced from annual reports of the selected firms were analysed using descriptive and inferential statistics. Specifically, static panel least square regression techniques were used.

Result: The results of the study revealed that company income tax (CIT) is positively related to the investment decision of the quoted manufacturing firm (INV), and thus enhances the investment of the quoted manufacturing firm (INV) in Nigeria. The probability value revealed that company income tax (CIT) had a statistical significant correlation with the investment of the quoted manufacturing firm in Nigeria. This implies that higher corporate income taxes are associated with lower investment in manufacturing firms.

Novelty: This study digressed from examining the effects of corporate tax on financial performance as that was the major focused area in this context. However, this study assessed its effect on investment decisions. Hence, this study was able to recommend that the Nigerian government should encourage and enhance manufacturing investment decision by designing an appropriate corporate income tax policy. An investment decision that is fostered on new capital, encourages the implementation of new production techniques and thus should be engineered for the development of manufacturing firms.
The Impact of Public Expenditure on Economic Growth: A Review of International Literature
Authors: Nyasha Sheilla , Odhiambo Nicholas M.
Published: December 2019

Research background: Although a number of studies have been conducted on the relationship between public expenditure and economic growth, it is difficult to tell with certainty whether or not an increase in public expenditure is good for economic growth. This lack of consensus on the results of the previous empirical findings makes this study of paramount importance as we take stock of the available empirical evidence from the 1980s to date.

Purpose: In this paper, theoretical and empirical literature on the relationship between government expenditure and economic growth has been reviewed in detail. Focus was placed on the review of literature that assessed the impact of government spending on economic growth.

Research Methodology: This study grouped studies on the impact of public expenditure on economic growth based on their results. Three groups emerged – positive impact, negative impact and no impact. This was followed by a review of each relevant study and an evaluation of which outcome was more prevalent among the existing studies on the subject.

Results: The literature reviewed has shown that the impact of government spending on economic growth is not clear cut. It varies from positive to negative; with some studies even finding no impact. Although the impact of government spending on economic growth was found to be inconclusive, the scale tilts towards a positive impact.

Novelty: The study provides an insight into the relationship between public expenditure and economic growth based on a comprehensive review of previous empirical evidence across various countries since the 1980s.
Assessment of the Development of the European Oecd Countries with the Application of Linear Ordering and Ensemble Clustering of Symbolic Data
Authors: Pełka Marcin
Published: December 2019

The research background of the paper covers the development of a country, that can be measured in various ways. Simple indicators, like GDP and also complex indicators such as HDI (human development index), can be used to measure country development. However, usually countries are divided into groups via setting some arbitrary levels of final measure. What is more, the composite (complex) indices have some problems and errors.

The main purpose of the paper is the assessment of the development of the selected European OECD countries with the application of the linear ordering and ensemble clustering of symbolic data as well as comparison of the ensemble clustering with a single model.

Research methodology covers linear ordering with the application of multidimensional scaling for a visualisation of results and ensemble clustering for symbolic data.

The results are compared according to adjusted Rand and silhouette indices. The obtained results show that ensemble clustering for symbolic data can be a useful tool in country development analysis and allows reaching better results than a single model.

The novelty of the proposed approach is to use a cluster analysis to obtain the clusters of countries with similar variables’ values (indicators of development) and the application of multidimensional scaling for symbolic data in order to visualise linear ordering results.
The Perspective of the Reform of the Constitution of Spain in View of the Institutional Status of Autonomous Communities
Authors: Dankowski Michał Zbigniew
Published: December 2019

Spain according to the Constitution of 1978 is a unitary state, but its whole territory is divided into autonomous communities that have the widest rights from equivalent territorial units in other European countries. The Constitution restored the possibility of creating regional autonomies, which were abolished earlier during the Franco dictatorship. However, the basic law was adopted before the foundations of regional structures were fully developed, so norms concerning the issues of autonomy were dictated in a general way. Only later legal acts regulated the situation in detail, but often their content depended on the political situation and was not always homogeneous. The creators of the Constitution did not foresee the subsequent forming of autonomous communities in the entire state territory. For over four decades of validity of the Spanish constitution, differences in the way the individual autonomous communities were established and differences in the competences of different regions have emerged. Some autonomous governments have also begun to expand their rights at the expense of the central authorities. The above factors caused a lively discussion among lawyers and politicians over the necessity of constitutional reform in the scope of the territorial system of Spain.
The Constitution – Chosen Premises Justifying the Need to Introduce Amendments
Authors: Przybojewski Jacek
Published: December 2019

Indication of conditions constituting necessity of modifications within the scope of the Constitution shall be considered while perceiving the leading role of the Constitution in Polish legal order. Constitutional regulations determine standards for the entire legal system of the Republic of Poland. It is also worth a while to consider the need for unambiguous determination of relations of constitutional norms, also with regard to the law of the European Union. Doubts appearing within the scope of systemic rules concern mainly regulations specifying the rule of division and balancing of powers. Actually, they consist in lacks with regard to organization of bodies of each of three powers. Another issue is improvement of solutions determining coexistence of government and local government administration within the broader scope of principles of uniformity of the state and decentralization of public power. The article presents an analysis related to the aforementioned issues.
Reverse Discrimination – How Fundamental Rights Might be Changed without Notice
Authors: Wojtyła Natalia
Published: December 2019

This article addresses the issue how meaning of fundamental rights might be amended by international treaties, based on example of non-discrimination principle, in particular context of putting own national in less favoured situation than non-national (reverse discrimination).

Two European Union (EU) member states, the United Kingdom (UK) and Poland, were then selected for testing the practice. The main reason for the choice of the UK and Poland lies on their opposite legislation tradition. Polish Constitution expressly prohibit any kind of discrimination, whereas in the UK there is no such an unified act.

Firstly, articles defined that the reverse discrimination is. Secondly, it seeks whether the possibility to offset losses from a subsidiary is treated equally to residents and non-residents. National provisions guarantee general rights and freedoms, but their scope and the meaning are continuously modified. Not only judgements of national courts, but also international treaties might define the true meaning of fundamental rights.

Authors: Jankech Timotej , Maliarová Mária , Martinka Nicholas
Published: December 2019

Methylxanthines such as caffeine, theophylline, theobromine are significant and widespread psychoactive substances. We developed the isocratic method with optimum composition of the mobile phase 90 % water: 10 % acetonitrile and confirmed repeatability of retention times and peak areas. The developed HPLC method was applied to determine the content of methylxanthines in selected types of black and green teas available on the market. Of the black teas (tea bags), the highest concentration of theobromine was found in Ceylon tea (18.98 mg.L−1). The highest concentration of caffeine was in a cup of Earl Gray tea (254.09 mg.L−1). Among loose black teas, the highest content of both theobromine and caffeine was found in Pu Erh Superior tea, where the theobromine content was 24.62 mg.L−1 and the caffeine content was 520.67 mg.L−1. Of green powder teas, highest caffeine content (306.46 mg.L−1) was in Shizuoka Matcha Premium and the highest content of theobromine (8.45 mg.L−1) was found in GABA Midori. From the loose green tea, the highest concentration of theobromine (12.85 mg.L−1) was in Lung Ching West Lake. The highest caffeine content (484.85 mg.L−1) was in Gyokuro Shizuoka Premium Tea. In both types of teas the amount of theobromine and caffeine was quantified, but the presence of theophylline was not proven. Data on contents of these metabolites in tea products are highly informative for consumers.
Treatment and remediation by the stabilization/solidification process based on hydraulic binders of soil contaminated by heavy metals
Authors: Sahnoune Rachid , Moussaceb Karim
Published: December 2019

Nature and the environment are affected by various human industrial and/or urban discharges. Remediation for this problem requires first and foremost an in-depth analysis and an overall characterization of the intrinsic properties of the pollution-receiving environments. Secondly it is necessary to predict in these environments the behavior of dangerous chemical species (here particularly heavy metals) in the long term. This study focuses mainly on a detailed characterization of 4 soil samples sampled in vicinity of wild dump-BOULIMAT located 15 km west of the city of Bejaia-Algeria. The samples were characterised by atomic absorption spectrometry, X-ray diffraction, Fluorescence X and Infrared spectroscopy. The data showed high concentrations of metallic elements especially Zn (2,651.8 mg.kg−1) and Ni (163.44 mg.kg−1) in the soil samples. For their remediation, the stabilization/solidification (S/S) process with hydraulic binders appeared promising in reducing the polluting power of metal. This approach has considerably reduced the content of pollutants; 98 % removal was obtained for Ni and 99 % for Zn. The XRD analysis technique revealed the occurrence or absence of metallic elements in the crystallized phases.

Published: December 2019

The literature review focuses on the effect of forest soil properties on infection of coniferous trees and stumps by Heterobasidion spores and further growth of mycelium from tree to tree. Spread of the fungus is greater in alkaline soil. Forest plantations on former agricultural lands have an increased risk of infection, due to lack of antagonistic soil microorganisms. In Latvia, severe infection of spruce stands by Heterobasidion root rot has been observed on peat soils.

Published: December 2019

The aim of the retrospective case-control study was to determine if the health-related quality of life of overweight and obese children is lower than for children with optimal weight, using the KIDSCREEN-52 survey of health-related quality of life. The study examined differences in health-related quality of life assessments between children with optimal weight, and obese and over-weight children, as well as evaluated parental assessments of the quality of life of their children. In total, 200 children aged 8 to 18 years and their parents participated in the study. The results of the study showed that the total quality of life of obese (p < 0.0001) and overweight (p = 0.008) children was lower than for children with optimum weight (p = 0.001). Also, the assessments of quality of life between parents of obese (p < 0.0001) and overweight (p = 0.001) children scored lower than those of parents whose children had optimal weight.
Diacrises and mixed emotions in the relationship between music and art cinema: teacher learning and training through multimodal experiences
Authors: Nuti Gianni
Published: December 2019

The study discusses the ability to develop metacognitive skills through experiences of contact with cinematic works that produce complex, multifaceted, emotional impacts understood by the body before they are understood by the mind. We investigate the relationship between music and images by identifying morphological profiles and the multimodal value of hybridized, dynamic and mutually changing phenomena [Zambaldi, 2016] in which we see ourselves [Gallese, Guerra, 2015]. We must emphasize that only by elaborating propositions, reordering reality according to grammatical codes and syntactic patterns, it is possible to circumscribe and amplify the power of communication and non-verbal relationships: the power of embodied cognition must not stop but foster the power of words
How to create meaningful learning experiences in an online environment: components from coding student reflections
Authors: Mardi Fatemeh H.
Published: December 2019

This paper examines the learning experiences using student reflections. Data collection was carried out by prompting undergraduate students to reflect on their worst and best experiences, accomplishments, and what they learned through online collaborative activities. The theoretical framework used to explore these experiences was the Community of Inquiry model, which claims the optimal learning experience is at the intersection of three presences (Garrison, Anderson, and Archer, 2000). How can we use these student perceptions of their experiences to create optimal learning experiences in an online environment? Specific teacher characteristics, sense of community, learner effort, sense of improvement and progress, student expectations of online classes, and the impact of feelings and emotion on other presences are some of the themes that surfaced through content qualitative analysis in this study. Students also responded to a validated survey (explicitly prompting the CoI presences) which revealed the impact of lack of student interest in course topics. These themes are valuable because they reveal significant components of students’ learning experiences which can be used to recreate optimal experiences in other settings. This paper builds on the theoretical framework by adding the student perspective and offering a codebook for qualitative content analysis of reflections.
Use of a social network class: an alternative to engage learners
Authors: Bebey Danielle M.
Published: December 2019

This document presents the modelling and engagement process that emerge from content creation on a social network device. The latter is used informally and collaboratively to provide a meaningful learning environment and to constitute the distant side of a blended learning. This device puts into perspective the use of social network that can be beneficial for training. It also shows a creative approach to a mediation initially designed for entertainment. This is an action research project conducted in the form of grounded theory in the context of a communication course. The results of this research make it possible to understand the stakes of distant social experience on training. They are useful to the trainer through the conceptual modelling of processes. They are also useful for research that addresses training issues such as engagement through information and communication technologies. We finally see that this device can serve as a springboard for more immersive technologies such as artificial intelligence.
Was it worth the effort? An exploratory study on the usefulness and acceptance of video annotation for in-service teachers training in VET sector
Authors: Boldrini Elena , Cattaneo Alberto , Evi-Colombo Alessia
Published: December 2019

In the field of teachers training of different levels (primary and secondary) and types (in-service and pre-service), exploiting video support for teaching practices analysis is a well-established training method to foster reflection on professional practices, self- and hetero-observation, and finally to improve teaching. While video has long been used to capture microteaching episodes, illustrate classroom cases and practices, and to review teaching practices, recent developments in video annotation tools may help to extend and augment the potentialities of video viewing. Various, although limited, numbers of studies have explored this field of research, especially with respect to in-service teachers training. However, this is less the case for Vocational Education and Training. The study presented here is a pilot experience in the field of in-service teachers training in the vocational sector. A two-year training programme using video annotation has been evaluated and analysed. The dimensions investigated are teachers’ perceptions on the usefulness, acceptance and sustainability of video annotation in teaching practices analysis. Results show a very good acceptance and usefulness of video annotation for reflecting on practice and to deliver feedbacks. Implications for the integration of a structural programme of analysis of practices based on video annotation are presented.
Teachers’ Professional Development on Media and Intercultural Education. Results from some participatory research in Europe
Authors: Ranieri Maria , Nardi Andrea , Fabbro Francesco
Published: December 2019

Media and intercultural education are being increasingly recognised as a fundamental competence for teachers of the 21st century. Digital literacy and civic competence are facing several new challenges in response to the intensification of migratory phenomena and the unprecedented spread of fake news, especially among adolescents at risk of social exclusion, but teachers’ professional development is still far from coping with this emerging need. Intercultural understanding and a critical use of media among adolescents have now become primary goals for the promotion of active citizenship. This article intends to provide some recommendations on how to support teachers’ professional development in the field of media and intercultural education. To this purpose, it presents and discusses the results of an action-research project aimed at teachers’ improvement of teaching skills about the media in multicultural public schools. The results are part of a larger European project “Media Education for Equity and Tolerance” (MEET) (Erasmus Plus, KA3), an initiative promoted in 2016–2018 by the University of Florence (Italy).

Published: December 2019

Changes are considered essential to every industrial enterprise since changes are unavoidable part of the existence and management of all types of organizations. It can be seen that, comparing to the past, variety of changes in organizations is increasing, increases their frequency, and the speed with which they need to be implemented. Appropriate chosen and applied management practices can help to manage the implementation of changes in the organization and employees to perform their work without growing concerns over changes. The aim of the paper is to present the results of research aimed at identifying the degree of conservatism and progressivism in attitudes towards change with respect to different generational groups of employees. A questionnaire method was used to collect data. The research sample consisted of employees of industrial enterprises and employees working in the public sector with a total of n = 79. Quantitative statistical methods and thought processes were used to process and interpret the obtained data. Processing of collected data was done in Microsoft Excel.
Differences in Approaches to Employment of Contemporary Generations on the Labour Market (on Example of Economics and Managerial Study Programmes)
Authors: Šafránková Jana Marie
Published: December 2019

The paper focuses on some current differences in the current two-generation approaches in the labour market to employment, working conditions and people management. The findings are based on repeated surveys since 2009 focused on the opinions of full-time and part-time students and graduates of some economic and managerial fields of three universities in the Czech Republic and the opinions of selected employees of several companies. The results show that some approaches to work and working conditions differ significantly by age of respondents.
