Authors: González Raúl César Romero , Zermeño Marcela Georgina Gómez 
Published: July 2017

Abstract
This research enquires about the Information and Communication Technologies preferences of students, teachers, and school principals in the teaching-learning process of a second language in 9th grade in two settings: Spanish for the Huichol people in a remote rural area and English for a private school in the city. The first case is situated in a rural Huichol community in the high mountain area of Jalisco, Mexico. The second one is located in a wealthy neighborhood in the Western Metropolitan area of Mexico City. A qualitative methodology with a heuristic and ethnographic design to investigate the reality of the daily use of technologies in both contexts for learning a second language. The instruments were the participant observation and in-depth interviews. Among the key findings are: (a) the participants tend to favor the use of technology for second language learning, (b) the bandwidth and the speed of the Internet is crucial to strengthen the immersion into the culture of a second language, (c) Educational communities support electronic enquiring, (d) there are similarities in the preferred search engines between the two populations, (e) the equity of education is hindered by school desertions, and (f) educational innovation requires that similar investigations take place to foster a full performance in the society of knowledge.
Metadiscourse in persuasive essays by elementary students in South Korea and the US
Authors: Kim Il-Hee 
Published: July 2017

AbstractThis study investigated metadiscourse in the persuasive essays of fourth graders from both urban and rural communities: 224 students in South Korea and 188 in the US. Each student was asked to write a persuasive essay in his or her native Korean or English in response to a story not previously read or discussed. Analysis with a taxonomy developed by Hyland (2004) indicated significant differences in the metadiscourse by country. In terms of interactive metadiscourse, South Korean students used more sentence-level transitions than U.S. students, who used more frame markers and endophoric markers. With regard to interactional metadiscourse, U.S. students used more hedges, boosters, engagement markers, and self-mentions in their essays. This study also compared the students′ essays by the type of community in which the writers lived. In the US the essays of students in rural communities contained more hedges, whereas those of students in urban areas included significantly more self-mentions. In South Korea, no significant difference was detected in the metadiscourse of students living in rural and urban areas.
Vincent Šikula: a story and fairy-tale narrator
Authors: Vitézová Eva 
Published: July 2017

Abstract
Vincent Šikula entered (also) children’s literature in the 1960s, i.e. during the years when crucial works of Slovak children’s literature were published. His works are interesting for children even nowadays because they are built on story-telling, interesting language, and, very often, quick action. Šikula’s poetics is based on not underestimating children. He did not determine in advance for whom his books are intended, since, in his opinion, they were appropriated by those whom they suited most. The paper discusses Šikula’s stories and fairy-tales with regard to the authorial narrative strategies.
The Cost-Effective Laboratory: Implementation of Economic Evaluation of Laboratory Testing
Authors: Bogavac-Stanojevic Natasa , Jelic-Ivanovic Zorana 
Published: July 2017

SummaryLaboratory testing as a part of laboratoryin vitrodiagnostic (IVD) has become required tool in clinical practice for diagnosing, monitoring and prognosis of diseases, as well as for prediction of treatment response. The number of IVD tests available in laboratory practice has increased over the past decades and is likely to further increase in the future. Consequently, there is growing concern about the overutilization of laboratory tests and rising costs for laboratory testing. It is estimated that IVD accounts for between 1.4 and 2.3% of total healthcare expenditure and less than 5% of total hospital cost (Lewin Group report). These costs are rather low when compared to pharmaceuticals and medical aids which account for 15 and 5%, respectively. On the other hand, IVD tests play an important role in clinical practice, as they influence from 60% to 70% of clinical decision-making. Unfortunately, constant increases in healthcare spending are not directly related to healthcare benefit. Since healthcare resources are limited, health payers are interested whether the benefits of IVD tests are actually worth their cost. Many articles have introduced frameworks to assess the economic value of IVD tests. The most appropriate tool for quantitative assessment of their economic value is cost-effectiveness (CEA) and cost-utility (CUA) analysis. The both analysis determine cost in terms of effectiveness or utilities (combine quantity and quality of life) of new laboratory test against its alternative. On the other hand, some investigators recommended calculation of laboratory test value as product of two ratios: Laboratory test value = (Technical accuracy/Turnaround time) × (Utility/Costs). Recently, some researches used multicriteria decision analysis which allows comparison of diagnostic strategies in terms of benefits, opportunities, costs and risks. All analyses are constructed to identify laboratory test that produce the greatest healthcare benefit with the resources available. Without solid evidence that certain laboratory tests are cost-effective, laboratory services cannot be improved. Consequently, simple policy measures such as cost cutting may be imposed upon many laboratories while patients will have limited access to laboratory service.
Law and Development as a Field of Study: Connecting Law with Development
Authors: de Moerloose Stéphanie 
Published: July 2017

AbstractThis article introduces a series of papers prepared for the “2016 Law and Development Conference: From the Global South Perspectives,” held in Buenos Aires, Argentina and co-sponsored by Universidad Austral, the Law and Development Institute and the Inter-American Development Bank’s Institute for the Integration of Latin America and the Caribbean (INTAL). The introduction aims to show one of the major contributions from the law and development field of study: scholars reveal the frequent disconnection between law and development; then, by uncovering contextual factors and proposing innovative solutions, they reconnect law with development. This provides an important support for the adoption of national development policies and the implementation of international development projects. Over forty years after the seminal paper by Trubek and Galanter,
Elliptic operators on refined Sobolev scales on vector bundles
Authors: Zinchenko Tetiana 
Published: July 2017

Abstract
We introduce a refined Sobolev scale on a vector bundle over a closed infinitely smooth manifold. This scale consists of inner product Hörmander spaces parametrized with a real number and a function varying slowly at infinity in the sense of Karamata. We prove that these spaces are obtained by the interpolation with a function parameter between inner product Sobolev spaces. An arbitrary classical elliptic pseudodifferential operator acting between vector bundles of the same rank is investigated on this scale. We prove that this operator is bounded and Fredholm on pairs of appropriate Hörmander spaces. We also prove that the solutions to the corresponding elliptic equation satisfy a certain a priori estimate on these spaces. The local regularity of these solutions is investigated on the refined Sobolev scale. We find new sufficient conditions for the solutions to have continuous derivatives of a given order.

Dynamics of multivalued linear operators
Authors: Chen Chung-Chuan , Conejero J. Alberto , Kostić Marko , Murillo-Arcila Marina 
Published: July 2017

Abstract
We introduce several notions of linear dynamics for multivalued linear operators (MLO’s) between separable Fréchet spaces, such as hypercyclicity, topological transitivity, topologically mixing property, and Devaney chaos. We also consider the case of disjointness, in which any of these properties are simultaneously satisfied by several operators. We revisit some sufficient well-known computable criteria for determining those properties. The analysis of the dynamics of extensions of linear operators to MLO’s is also considered.
Only finitely many Tribonacci Diophantine triples exist
Authors: Fuchs Clemens , Hutle Christoph , Irmak Nurettin , Luca Florian , Szalay László 
Published: July 2017

Abstract
Diophantine triples taking values in recurrence sequences have recently been studied quite a lot. In particular the question was raised whether or not there are finitely many Diophantine triples in the Tribonacci sequence. We answer this question here in the affirmative. We prove that there are only finitely many triples of integers 1 ≤ u < v < w such that uv + 1, uw + 1, vw + 1 are Tribonacci numbers. The proof depends on the Subspace theorem.

The super socle of the ring of continuous functions
Authors: Ghasemzadeh Sahar , Karamzadeh Omid A. S. , Namdari Mehrdad 
Published: July 2017

Abstract
We introduce and study the concept of the super socle of C(X), denoted by SCF
(X) (i.e., the set of elements of C(X), which are zero everywhere except on a countable number of points of X). Using this concept we extend some of the basic results concerning CF
(X), the socle of C(X), to SCF
(X). In particular, we determine spaces X such that CF
(X) and SCF
(X) coincide. Spaces X such that Ann(SCF
(X)) is generated by an idempotent are fully characterized. It is shown that SCF
(X) is an essential ideal in C(X) if and only if the set of countably isolated points (i.e., points with countable neighborhoods) of X is dense in X. The one-point Lindelöffication of uncountable discrete spaces is algebraically characterized via the concept of the super socle. Consequently, it is observed that whenever Ox
⊆ SCF
(X) and SCF
(X) is a regular ideal (von Neumann), then X is either a countable discrete space or the one-point Lindelöffication of an uncountable discrete space. Consequently, in this case SCF
(X) is a prime ideal in C(X) (note, CF
(X) is never prime C(X))
Finiteness of the discrete spectrum in a three-body system with point interaction
Authors: Yoshitomi Kazushi 
Published: July 2017

Abstract
In this paper we are concerned with a three-body system with point interaction, which is called the Ter-Martirosian–Skornyakov extension. We locate the bottom of the essential spectrum of that system and establish the finiteness of the discrete spectrum below the bottom. Our work here refines the result of [MINLOS, R. A.: On point-like interaction between n fermions and another particle, Mosc. Math. J. 11 (2011), 113–127], where the semi-boundedness of the operator is obtained.

AbstractThis paper focuses on studying the antibacterial effect ofHibiscus sabdariffaextracts, a plant known in traditional medicine for its beneficial effects on the body.Hibiscus sabdariffaextracts were done in pure water, 50% ethyl alcohol, and 96% ethyl alcohol; the concentrations used to determine antibacterial activity were 1:1, 1:5, 1:10, 1:25, 1:50, noted cu 1, 2, 3, 4, 5. The antibacterial effect of the extracts was tested using the impregnated disk-diffusion method on bacteriaEscherichia coliATCC 25922,Salmonella typhimuriumATCC 14028,Enterobacter clocaeATCC 13047,Klepsiella pneumoniaeATCC 13833,Staphylococcus aureusATCC 29213,Yersinia enterocoliticaATCC 9610. We ascertained that the most efficient extracts were those obtained using 96% ethyl alcohol, 1:1 concentration onEscherichia coliATCC 25922 andEnterobacter clocaeATCC 13047 strains, where the inhibitory action presented average values between 5.43 mm and 3.43 mm. In the case ofKlepsiella pneumoniaeATCC 13833 andYersinia enterocoliticaATCC 9610 strains, the extracts recorded minimum or zero values. The antibacterial activity ofHibiscus sabdariffadepended on their concentration, on the solvent used, as well as on the resistance of the bacteria under study to the bioactive compounds in them.
Flexible Believers in the Netherlands: A Paradigm Shift toward Transreligious Multiplicity
Authors: Kalsky Manuela 
Published: July 2017

Abstract
The Netherlands has undergone a radical religious transformation through secularization, individualization and migration. Expressions of Christian belief are no longer strictly defined by the Church and hybrid forms of religiosity incorporating other religions have emerged. After a brief sketch of Dutch religious plurality, the author focuses on interviews with ‘flexible believers’, people who combine elements from different religious traditions and worldviews. Through interviews, she discovers a number of characteristics of these multiple religious believers (MRB) - interviewees - such as ritual praxis, identity-making processes and belonging - and reflects on their impact for the wider picture of religiosity in today‘s post-Christian Dutch network society. She concludes that hybrid forms of lived religion like mrb, present a challenge to traditional concepts of religious identity and belonging. They require a paradigm shift from an ‘either/or’ to a relational ‘as well as’ approach within a rhizomatic network of meaning.
The Influence of Hyperoxia On Heat Shock Proteins Expression and Nitric Oxide Synthase Activity – the Review
Authors: Szyller Jakub , Kozakiewicz Mariusz , Siermontowski Piotr 
Published: July 2017

Abstract
Any stay in an environment with an increased oxygen content (a higher oxygen partial pressure, pO2) and an increased pressure (hyperbaric conditions) leads to an intensification of oxidative stress. Reactive oxygen species (ROS) damage the molecules of proteins, nucleic acids, cause lipid oxidation and are engaged in the development of numerous diseases, including diseases of the circulatory system, neurodegenerative diseases, etc. There are certain mechanisms of protection against unfavourable effects of oxidative stress. Enzymatic and non-enzymatic systems belong to them. The latter include, among others, heat shock proteins (HSP). Their precise role and mechanism of action have been a subject of intensive research conducted in recent years. Hyperoxia and hyperbaria also have an effect on the expression and activity of nitrogen oxide synthase (NOS). Its product - nitrogen oxide (NO) can react with reactive oxygen species and contribute to the development of nitrosative stress. NOS occurs as isoforms in various tissues and exhibit different reactions to the discussed factors. The authors have prepared a brief review of research determining the effect of hyperoxia and hyperbaria on HSP expression and NOS activity.
Impact of personality-oriented programs of physical rehabilitation on the heart rate variability in women with post-mastectomy syndrome
Authors: Odinets Tatiana , Briskin Yuriy 
Published: July 2017

AbstractIntroduction. The aim of the study was to determine the effect of personality-oriented physical rehabilitation programs on the heart rate variability in women with post-mastectomy syndrome. Methods. The following methods were applied: theoretical analysis of scientific and methodologic literature data, heart rate variability analysis, and mathematical statistical methods. The subjects of the study were 50 women with late symptoms of post-mastectomy syndrome. The study was conducted during the ambulatory rehabilitation stage after Madden radical mastectomy. All the indicators of the heart rate variability were equivalent in the main and comparison groups at the beginning of rehabilitation. The impact of training was examined every 6 months over the course of a year. Results. Measurements were taken three times: at the beginning of rehabilitation and after 6 and 12 months. It was found that most of the investigated parameters of heart rate variability in both groups steadily improved during the year of rehabilitation. The average values of stress index and amplitude of mode after 12 months of rehabilitation were lower in the main group than in the comparison group but the values of the standard deviation of normal-to-normal intervals and the very low-frequency component of the spectrum were better by 6.48 ms (p < 0.05) and 203.29 ms2 (p < 0.05), respectively. Conclusions. The personality-oriented programs of physical rehabilitation were effective in augmenting heart rate variability and restoring autonomic balance in patients with post-mastectomy syndrome.

The Valuation of Hope Value for Real Estate Development
Authors: Renigier-Biłozor Małgorzata , d’Amato Maurizio 
Published: July 2017

AbstractIn the valuation of a property subject to development, the valuer may consider the potential aspect of the value of both land to be improved and a building to be refurbished. These kinds of valuations are complex, especially when a prudent assessment of value is required. In general terms, all properties may have potential development which, in some cases, can be termed “hope”. In particular, uncertainty regarding the change in the legal framework may create expectations as to the uncertain variation of property value in the future. In these cases, it may be necessary to deal with hope value or future value, trying to reach the value of a property subjected to uncertain changes. Hope value is the difference between the existing use value and the price that the market might pay for future transformation. The main aim of the paper is the elaboration of a methodology to determine the hope value. In this work, a real option model for the valuation of hope value in the real estate market will be applied to a small sample of residential properties located in Olsztyn that are subject to possible transformation. The possibility of a transformation may create expectations and may influence the value of the property. Although the applications of these methods to real estate valuation are fairly recent, the International Valuation Standards have included real option theory in the income approach as a valuation method since 2011.
