The results of the field and biochemical researches of sweet cherry Prunus avium L. scion Chermashnaya fruit grown on 8 clonal stocks (Kolt, Moskoviya, Izmaylovskiy, Stepnoy rodnik, AVCH-2, VSL-2, VTS-13, V-5-88) are presented. Trees productivity, the fruit average weight and the stone- fruit weight relation were studied, fruit degustation evaluation was fulfilled and the main biochemical parameters such as soluble solids, sugars sum, ascorbic acid concentration and antioxidant activity were determined. The influence of the stock on the fruit biochemical composition, the trees productivity and the fruit weight was determined. The sweet cherries productivity was 12,5 kg/tree at average, and depending on the stock it varied from 8,3 kg/tree (V-5-88) to 18,6 kg/tree (Izmaylovskiy). The biggest fruit were found on the trees with stocks VSL-2, Izmaylovskiy and AVCH-2. At average the proportion of the stone in the fruit weight was 5.3% with the variation depending on the stock from 5.2% (Kolt) to 5.5% (V-5-88, Stepnoy rodnik). According to the degustation results the fruit of scion Chermashnaya were characterized by the sweet harmonized taste and smell (4.5 points), there were not found either taste deterioration or bitterness on any stock. The best results according to the degustation evaluation by the parameters complex were found at scion Chermashnaya combinations on stocks Izmaylovskiy, VSL-2 and Kolt. The soluble solids content also depended on the stock and varied from 13.9 (Chermashnaya on AVCH-2) to 17.2% (Chermashnaya on Izmaylovskiy) at average value 16.0%. The sugars content in the sweet cherry fruit was within the range from 9.0 to 12.4%. The sugars higher accumulation belonged to the combinations of Chermashmaya on Stepnoy rodnik (11.1%) and Chermashmaya on Izmaylovskiy (12.4%). The ascorbic acid content in the sweet cherry fruit did not exceed 8 mg.100 g-1. Depending on the stock this parameter varied from 5.9 to 9.3 mg.100 g-1. The highest vitamin C content was found in the fruit at the grafting on the stock Stepnoy rodnik, the lowest one - on the stock Moskoviya. The sweet cherry fruit antioxidant activity according to DPPH method was not high and was in the range from 11.8 to 13.8%.
Modeling of urease thermal inactivation processes in soybean at high-temperature micronization
Authors: Zverev Sergey , Sesikashvili Otari 
Published: July 2018

The use of soybean, in particular in forage production without preliminary heat treatment is not appropriate, and sometimes dangerous, because of the presence of antinutrients. As a marker in assessing safety of cakes and meals, there is often used urease in forage production. This paper describes the results of thermal inactivation of urease in soybean during the process of high-temperature micronization (heating of grain in the flux of infrared radiation). There have been obtained the empirical dependencies of the degree of its inactivation on time of heat treatment and energy exposure (the product of irradiation by the time of treatment). The similar dependences of urease activity on grain temperature are invariant to infrared heating (irradiation and time) regimes, but their nature is affected by the initial moisture content. The paper proposes the models of inactivation of antinutrients based on of the first-order equations of chemical kinetics with the reaction rate constant in various forms (Arrhenius and Hinshelwood, the transition state theory). The models have been tested on literature data on the inactivation of a trypsin inhibitor at a constant temperature. The models are further refined taking into account the variable (increasing) temperature and are reduced to the simplest form: Y= k [Exp (-εR/T) - T0 еxp (-εR/T0)], where T, T0- are the current and initial temperatures of grain, k, εR - theempirical coefficients. The identification of the model coefficients was carried out based on the results of inactivation of urease during heating in the flux of infrared radiation. It has been established that the results of thermal inactivation of soybean do not depend on the IR processing regimes and are determined only by the initial moisture content of grain, and by the end heating temperature. The efficiency of inactivation is higher the higher is the used irradiation. There is a compensating effect - with the growth in one coefficient, another is also increased. The considered models can be used for the thermal degradation processes and other thermolabile substances.

Published: July 2018

The impact of different types of vermicomposts as well as different species and genera of earthworms on the quantity of the cultivated crops yield has been studied for decades. There is scarce information about the effects of these factors on the quality of plant production. One of the qualitative parameters of vegetables, to which a special attention is paid, is the content of antioxidants (vitamin C, total polyphenols and other substances). The pot experiment carried out in the vegetation cage studied: A) the influence of soil itself, soil mixed with vermicompost in a ratio of 4:1; B) the influence of earthworms number (genus Eisenia foetida, 10 and 20 individuals per pot) supplied to soil mixed with vermicompost in a ratio of 4:1 on the weight of radish roots and leaves, to the total chlorophylls content in leaves, to the selected qualitative parameters of the roots and leaves (vitamin C, total polyphenols content, total antioxidant activity). The results showed that the supplementation of vermicompost into soil increased the content of the total chlorophylls in leaves. The carrot roots and leaves yield has also been risen. In the roots the content of vitamin C and content of total polyphenols (TPC) was decreased and the total antioxidant activity (TAA) dropped, too. The increased content of vitamin C and TPC was detected in leaves. The inoculation of soil containing vermicompost by earthworms increased the root yield and TAA in roots. It increased the content of vitamin C and TPC in leaves. From the viewpoint of antioxidant content (vitamin C and total polyphenols) the leaves are more attractive than a root.

Published: July 2018

Abstract
“An Unaccompanied Refugee children is a person under the age of 18, who is afraid of being persecuted, whose rights are threatened and is forced to leave his / her habitual residence and / or country of origin and is outside it, without the accompaniment of parents, relatives or other adult person, who, by law or custom, is responsible. “ (Angelidou & Aguaded, 2016). According to the Human Rights Watch researches (2016), serious crimes against refugees and immigrants children are being committed. The Government of Spain announced that they expect to relocate a total of 586 people before the end of 2017. At present, the number of refugees in Spain is more than 470. Specifically, Andalusia became, in September 2016, the first Spanish community that manages to relocate unaccompanied refugees children. The objective of this research is to analyze the socio-educational intervention, which is being carried out with these children. For this, the method used was in-depth interviews, y cuestionarios, which results offer very diverse information, from which we can conclude that there is a way forward, which is leading to improvements for children.
Introducing Everyday ‘Digital Literacy Practices’ into the Classroom: An Analysis of Multi-layered Media, Modes and their Affordances
Authors: Creer Adele 
Published: July 2018

Abstract
Integrating digital media into classroom practice requires consideration on many levels, how young people access and engage with digital media at the level of media, mode and genre is complex and may redefine how literacy practices in the classroom are perceived. Young people use digital media in their everyday literacy practices and a failure to embrace new technologies in the classroom may lead to a disjuncture between their everyday and college-assessed literacy practices.
Following an analysis of communicative interactions that looked at multi-layered media, modes and their affordances, this paper offers insights from recent research. It looks carefully at the congruence and incongruences that exists between the two literacy practices with the aim to offer rich insights into meaning making in what are comparatively new, digital literacy practices.
A major conclusion is that some assessment tasks do have congruence with young people’s everyday literacy practices but at times they either do not take account of the students ‘funds of knowledge’ (Moll et al.,1992) to the full which is likely to cause confusion and possible under performance.

Published: July 2018

Abstract
The 2010 President’s Council of Advisors on Science and Technology indicated that there was a need to provide individuals with strong STEM (Science, Technology, Engineering, and Mathematics) backgrounds in order to be a competitive country internationally. Additionally, it has been found that there is a gender gap in STEM related fields. Therefore, this article describes theories related to the gender gap in the STEM field and ways to engage girls in STEM related fields in order to close the gender gap. The researchers of this study did extensive research to review the current literature, condense and summarize the findings from various studies, and provide steps for educators to engage in that will create an early atmosphere of positive learning environments for girls to be curious about STEM concepts.
Thresholds of Change in Children’s Literature: The Symbol of the Mirror
Authors: Arlandis Sergio , Reyes-Torres Agustín 
Published: July 2018

Abstract
This article approaches the study of children’s literature as a threshold of change that allows readers to explore the reality around them, imagine other worlds and understand other perspectives. Based on the notion of the child’s cognitive development organized into four stages ―pre-reading, fantastic stage, fantastic-realistic stage and aesthetics stage― reading becomes a resource to combine fantasy and experience where the mirror is a highly suggestive element and prone to hundreds of interpretations and applications as can be seen in the plots of well-known books such as the brother Grimm’s Snow White, Lewis Carroll’s Through the Looking-Glass, Michael Ende’s The Neverending story and J.K. Rowling’s The Philosopher’s Stone, among others. As a result, as young readers go from one stage to another, the mirror gains greater symbolic complexity and they face the discovery of the self and the other as well as the confrontation between the so-called primary and secondary worlds, reality and the marvelous.

Authors: García-Umaña Andrés , Tirado-Morueta Ramón 
Published: July 2018

Abstract
The increase in the use of information technologies encompasses all educational and social issues, even changing intergenerational skills. It is considered that the most conditioned to this effect are adolescents and young people. This research is a literary review of various studies on addiction and Internet abuse and presents relevant results of the situation of college students and their level of Internet use. The study was developed in seven educational units of Ecuador, with a sample of n = 773 students (53.6% men and 46.4% women). An instrument with sufficient validation guarantees (α.94) has been applied, verified by means of a factorial analysis of main components, which determined two study factors in the use of the Internet and loss of control and interference with life. Through a statistical treatment (Pearson) a good correlation was established (,62) between the two study dimensions, which is a concern in the educational field.
E-Teaching in Higher Education: An Essential Prerequisite for E-Learning
Authors: Guri-Rosenblit Sarah 
Published: July 2018

Abstract
The discourse on the implementation of the digital technologies in higher education settings focuses mainly on students’ learning rather than on professors’ teaching. The little attention paid to the crucial role of teachers in online settings results in a restricted and moderate adaptation of the technologies in higher education worldwide. In most higher education institutions, the new technologies are used mainly for add-on functions and not for substituting face-to-face encounters or for an intensive web-enhanced teaching. This article starts with briefly explaining why most students, particularly at the undergraduate level, are unable and/or unwilling to study by themselves without expert teachers to guide their knowledge construction, discusses the problematics of digital literacy of teachers, examines the main reasons for the reluctance of many academics to utilize the technologies more fully in their teaching, and concludes by recommending some strategies for incorporating more fully the huge array of the technologies’ capabilities in higher education institutions.
Non-technological Learning Environments in a Technological World: Flipping Comes to the Aid
Authors: Froehlich Dominik E. 
Published: July 2018

Abstract
We live in a world permeated by digital technologies. Still, however, this digitization is not always reflected in the learning environments of higher education institutions, which raises questions about the adequacy of the instructional outcomes. In this paper, I maintain that the concept of the inverted or flipped classroom may be a fruitful path to including learning “hands-on” with technology even in learning environments absent of any technological resources. The rationale for this proposition is that flipped elements transfer the demand for technology from the teaching environment to the student. I report on a design-based research project to put this claim to a first test. The qualitative and quantitative data collected all support the idea that flipped classroom elements may help overcome differences in terms of availability of technology in different learning environments. The implications for universities and higher education teachers are discussed.

Abstract
This study conducted a general and comparative analysis of how university students use mobile digital devices for educational purposes in various places and spaces both inside and outside university facilities in Spain and Latin America. It analyses a total sample of 886 students (442 Spanish and 444 Latin American) corresponding to five Spanish and five Latin American universities. The research methodology was based on factorial analysis and comparison between groups with parametric and nonparametric tests. The results show that educational use of mobile digital devices in the Hispanic world concentrates on the use of smartphones and tablets inside university facilities; primarily in college cafeterias, corridors, classrooms and libraries. Spanish and Latin American students used tablets in and out of University facilities for storing and retrieving information, and smartphones for sharing educational information and content.
Lifelong Learning at Universities: Future Perspectives for Teaching and Learning
Authors: Cendon Eva 
Published: July 2018

Abstract
This paper examines practices of teaching and learning in the era of digitalization. More specifically, it addresses practices of teaching and learning for students with professional experience who work alongside their studies. Based on the assumption that digitalization is a means of allowing more open and flexible pathways for teaching and learning in higher education, the paper focusses on the perspectives and perceptions of both students and teachers in digital supported teaching and learning environments as forms of blended learning. It brings together findings from two qualitative empirical studies: one focused on students’ perspectives of their development over the course of their studies; the second addressed teachers’ perspectives and their teaching strategies and activities. Based on the findings of these two research studies, the paper outlines future perspectives for teaching and learning and the role of digitalization, with a particular emphasis on programs of lifelong learning at universities.
Plagiarism, Internet and Academic Success at the University
Authors: Torres-Diaz Juan Carlos , Duart Josep M. , Hinojosa-Becerra Mónica 
Published: July 2018

Abstract
In this work, we determined, the level of incidence of the use of technologies on academic success and the incidence of interaction and experience on the level of plagiarism of university students. A sample of 10,952 students from 31 face-to-face universities in Ecuador was created. Students were classified based on their experience level, level of interaction with teachers and classmates, and the use they do with technology for academic activities. The results showed that the level of experience does not affect academic success, but does have an incidence on plagiarism levels that increase as this experience increases. Plagiarism reaches higher levels when level of experience, family income and hours of connection per day increases. Academic performance depends on the number of hours that students seek information and the number of academic videos they watch. Also, plagiarism tends to decrease as the student makes better use of technology for their academic activities.

Published: July 2018

AbstractThis study examines the individual and contextual factors associated with sociopolitical control expressed by immigrants in southern Spain. We used hierarchical linear modeling to evaluate the relations between individual (community participation, social connectedness, and perceived cultural competence of receiving community services) and municipality characteristics (city community participation, city social connectedness, and city community services’ cultural competence) and immigrants’ feelings of sociopolitical control. Data were analyzed using a two‐level model based on 707 Moroccan immigrants in 25 municipalities. After adjusting for gender, educational level, and psychosocial confounding factors, we observed a positive association between social connectedness and sociopolitical control at the individual level. At the contextual level, we observed a positive association between (a) city community participation, (b) city social connectedness, and (c) city community services’ cultural competence, and sociopolitical control. Indeed, living in a municipality where there are community services with high levels of cultural competence and where, on average, many people participate in organizations and neighbors are connected, was associated with higher levels of perceived control in the sociopolitical domain for immigrants. We also discuss implications for community‐based research and practice.

Published: July 2018

BackgroundProlonged length of stay (pLOS), disease‐related complications, and 30‐day readmissions are important quality metrics under the Affordable Care Act. The purpose of our study was to investigate the effect of patient‐level and hospital‐level factors on these outcomes for patients admitted for transsphenoidal pituitary surgery.MethodsThe Statewide Planning and Research Cooperative System (SPARCS) database was queried to investigate 30‐day readmissions and pLOS for transsphenoidal pituitary surgery in New York from 1995 to 2015. Multivariate logistic regression, adjusting for patient and hospital characteristics, was performed to assess the effect of these variables on the outcomes of interest.ResultsA total of 9950 patients underwent transsphenoidal pituitary surgery; 7122 (72%), 2394 (24%), and 434 (4%) patients were treated at high‐volume, medium‐volume, and low‐volume centers, respectively. Patient factors associated with treatment at high‐volume centers (HVCs) included: top income quartile, private insurance, urban residence, and white or Asian race (p < 0.05). Patient variables associated with treatment at low‐volume centers (LVCs) included: age >65 years, elevated Charlson comorbidity index (CCI) scores, bottom income quartile, Medicaid and Medicare insurance, rural residence, black race, and Hispanic ethnicity (p < 0.05). Variables predictive of prolonged hospitalizations in our multivariable model included black race, Hispanic ethnicity, Medicaid insurance, low income, female gender, LVC, and comorbidities (panhypopituitarism, hypothyroidism, diabetes insipidus [DI], visual disturbances, CCI) while predictors of readmissions included Asian race, female gender, and comorbidities (Cushing syndrome, DI, CCI).ConclusionPatients undergoing transsphenoidal pituitary surgery at HVCs have shorter hospitalizations, fewer postoperative electrolyte abnormalities, and lower charges; however, socioeconomic factors may influence access to quality care.
