Course Curricular Design and Development of the M.Sc. Programme in the Field of Ict in Education for Sustainable Development
Authors: Makrakis Vassilios , Kostoulas-Makrakis Nelly 
Published: April 2013

Abstract
This paper presents the design and development of a virtual learning enviroment (VLE) for a M.Sc. programme on information and communication technologies (ICTs) in education for sustainable development (ESD) driven by a learning paradigm that merges three theories of learning, namely: experiential learning, constructivist learning and transformative learning (ExCon- Tra) funded by the European Commission. Learning activities were designed to offer the chance for students to interact asynchronously and synchronously, negotiate meaning and reflect on their learning and viewpoints through collaborative problem solving. The ExConTra learning process is also based on an interdisciplinary approach addressing the four pillars (environment, society, culture and economy) of sustainable development and makes use of an online course design methodology that uses four phases: needs analysis, curriculum design, development and formative evaluation. The VLE that encompasses both the curriculum programme and the online platform with its tools and online technologies merges ICTs with ESD in three ways: a) providing opportunities to target groups for reflective practice; b) using open source ICT tools and ESD-related learning objects available in the Web and c) using ICTs to develop interactive, interdisciplinary and cross-disciplinary ESD learning activities

Published: April 2013

Abstract
The paper describes an action research during the implementation of an e-learning course on commercial studies in a bachelor’s programme. The action research study aims to: 1) determine the effectiveness of action research in a technologically-based learning environment and 2) establish how group work in e-learning environment affects students’ interest in, and need for, communication and discourse. Qualitative and statistical methods of data analysis were used in this mixed-methods study. The present paper analyses the experience of students working in three action phases to design their personal frames of reference for evaluation of the content and metacontent of business fundamentals. The study identified several possibilities for improving e-learning environment with techniques that make this form of learning more sustainable.
Winter diet composition of urban long-eared owls (Asio otus) in Rzeszów (SE Poland)
Authors: Dziemian Sylwia , Piłacińska Barbara , Pitucha Grzegorz 
Published: April 2013

Abstract
Diet variation of the long-eared owl (Asio otus Linnaeus, 1758) was investigated on the basis of pellets collected in winter season 2007/2008 from a communal roosting site in a municipal cemetery in Rzeszów (a city in south-eastern Poland). We assumed that the proximity of human settlements would affect the diet composition of this predator, resulting in a higher proportion of species associated with urban habitats. Although voles, especially the common vole Microtus arvalis, were still the most important prey, mice constituted approximately 17% of all prey items, with the field mouse Apodemus agrarius being most frequent. Food niche breadth was wider in December than in March. Our results suggest that owls from Rzeszów hunt mostly in open habitats surrounding the city, where they can still capture their basic prey species. Yet, they can broaden their diet with species of murids associated with the mosaic urban and suburban habitats.
Invasive giant knotweed (Fallopia sachalinensis) alters the composition of oribatid mite communities
Authors: Skubała Piotr 
Published: April 2013

Abstract
Plant invasions are a serious global threat to biodiversity and ecosystem stability. The invasive giant knotweed Fallopia sachalinensis (synonym: Reynoutria sachalinensis) is one of the most aggressive plant invaders in many countries. It forms dense stands that prevent other species from growing. To assess the impact of the knotweed, oribatid mite communities were studied under Fallopia-free native vegetation and at Fallopia-infested sites (2 types: 90-100% and 30% of coverage) with similar soil. All the sites are located in mixed forest in the Kraków-Częstochowa Upland (Jura Krakowsko-Częstochowska) in south Poland. Species composition and functional group composition of oribatid mite communities were compared. In total, 1540 specimens belonging to 70 oribatid species were collected from 90 soil samples. This successful exotic invasive species had a moderate influence on species richness (20% less species at the totally invaded site than at the Fallopia-free site) and a profound effect on soil oribatid mite community composition. Several oribatid species characteristic of a particular site were observed. Shifts were detected in proportions of groups with different habitat specificity (e.g. higher proportion of eurytopic mites at invaded sites), ecomorphological groups (e.g. lower proportion of litter-dwelling mites at invaded sites), trophic groups (e.g. lower proportion of macrophytophagous mites at invaded sites) and zoogeographical groups (e.g. higher proportion of mites with broad geographical distribution at invaded sites). These observations prove the radical negative change of environmental conditions for soil oribatid mites as a result of Fallopia invasion. The increase in sexually reproducing oribatid mites at invaded sites suggests that this way of reproduction is preferable when resources are in shortage.
Margaret Fuller’S Conversations: Speaking as Revision and Feminist Resistance
Authors: Quawas Rula 
Published: April 2013

Abstract
Conversation as a means to social, intellectual, and spiritual self-culture was advocated during the American Romantic period by members of the Transcendental movement. Margaret Fuller was a transcendental conversationalist who challenged the theoretical setting and practice of self-culture, remedied the gap in it about concepts of womanhood that were imposed by the culture of the time and that attempted to determine women’s place in the symbolic order, and placed an emphasis on self-knowledge, whatever the subject matter. She came to represent a rhetoric whose aim was to foster community, moral truths, ethical actions, and feminist resistance. Fuller fully subscribed to the idea of the revelatory power in conversation and provided women with an opportunity to develop the intellectual rigor necessary to establish their own identities in the world: public or private. Through her weekly conversations for Boston women, held from 1839 through 1844, she used conversation or speaking as revision to explore philosophical, aesthetic, and sociocultural questions and supplied access to education from which women were excluded. Women who speak in public, if they have a moral power ... that is if they speak for conscience’ sake, to serve a cause which they hold sacred ... subdue the prejudices of their hearers (Margaret Fuller, Woman in the nineteenth century, 110).
Lexical Borrowings and Calques From African American Slang in Polish Youth Slang – A Study Based on A Selected Internet Forum
Authors: Dylewski Radosław , Jagodziński Piotr 
Published: April 2013

Abstract
The aim of the article is to present a very preliminary chunk of a wider study of Polish slang, whose aim is to pinpoint lexical influence of American English in broad terms and the usage and understanding among Polish youngsters of various types of borrowings. More specifically, the authors have concentrated on the borrowings of words, phrases and meanings from a sociolect known as African American English to the language of Polish youngsters. To this end, the largest Polish hardcore punk Internet forum has been scrutinized. The conducted analysis points to a discernible, albeit not significant lexical influence of the sociolect on the Polish youth slang, which calls for a more nuanced, survey-based analysis the authors wish to undertake as part of their research project.
Memory and Forgetting in Lisa Appignanesi’S the Memory Man
Authors: Drewniak Dagmara 
Published: April 2013

Abstract
The aim of this paper is to look at Lisa Appignanesi’s novel The memory man ([2004] 2005), which won the 2005 Holocaust Literature Award, and examine the patterns of remembering and forgetting as indispensable aspects conducive to the formation of Jewish identity. The main character of the book, Bruno Lind, a Holocaust survivor and a scientist dealing professionally with the complicated neurological issues of remembering and losing memory, tries to recollect his war memories during a journey to the places of his youth which are at the same time the sites of his and his family’s trauma. The Holocaust, change of identities, the war memories and finally the stay at the DP camps and escape to Canada return to Bruno Lind’s mind in order to be passed onto the next generation and remembered. This article shows Appignanesi’s novel as an important contribution to the discussion on the role of memory in Jewish identity.
When William Met Mary: The Rewriting of Mary Lamb’S and William-Henry Ireland’S Stories in Peter Ackroyd’S The Lambs Of London
Authors: Chalupský Petr 
Published: April 2013

Abstract
Peter Ackroyd’s London novels represent a distinctive component in his project of composing a literary-historical biography of the city. Understanding London as a multilayered palimpsest of texts, Ackroyd adds to this ongoing process by rewriting the city’s history from new, imaginative perspectives. For this he employs approaches and strategies such as parody, pastiche, genre mixture, metafiction, intertextuality and an incessant mixing of the factual with the fictititious. The aim of this article is to explore the various ways in which he toys with historical reality and blurs the borderline between fiction and biography in The Lambs of London (2004), offering thus an alternative rendering of two unrelated offences connected with late eighteenth and early nineteenth century London literary circles: Mary Lamb’s matricide and William-Henry Ireland’s forgeries of the Shakespeare Papers.

Abstract
We study continuity points of functions with values in generalized metric spaces. We define the generalized oscillation, which is a useful tool in our study. Let X be a topological space and Y be a weakly developable space. Let ƒ
: X →Y be a function. Then the set C (ƒ) of continuity points of ƒis a Gδ-set in X. Some results concerning continuity points of separately continuous functions as well as functions with closed graphs are also given.

Some functional equations characterizing polynomials
Authors: Koclęga-Kulpa Barbara , Szostok Tomasz , Wąsowicz Szymon 
Published: April 2013

Abstract
We present a method of solving functional equations of the type where f, F: P → P are unknown functions acting on an integral domain P and parameteres are given. We prove that under some assumptions on the parameters involved, all solutions to such kind of equations are polynomials. We use this method to solve some concrete equations of this type. For example, the equation (1) for f, F: ℝ → ℝ is solved without any regularity assumptions. It is worth noting that (1) stems from a well-known quadrature rule used in numerical analysis.
On the family of [λ,ρ]-continuous functions

Published: April 2013

Abstract
In this paper, we introduce the class of [λ, ρ] -continuous functions. First, we investigate some relations between the classes of [ λ1, ρ1] and [λ2,ρ2] -continuous functions for different pairs [λ1,ρ1] , [λ2,ρ2]. Next, we give an equivalent condition for a function in order that it will belong to the discussed class.
Error-correcting codes and Minkowski’s conjecture
Authors: Horak Peter 
Published: April 2013

ABSTRACT
The goal of this paper is twofold. The main one is to survey the latest results on the perfect and quasi-perfect Lee error correcting codes. The other goal is to show that the area of Lee error correcting codes, like many ideas in mathematics, can trace its roots to the Phytagorean theorem a2+b2 = c2. Thus to show that the area of the perfect Lee error correcting codes is an integral part of mathematics. It turns out that Minkowski’s conjecture, which is an interface of number theory, approximation theory, geometry, linear algebra, and group theory is one of the milestones on the route to Lee codes.

Abstract
The aim of this work is to study asymptotic properties of the third-order quasi-linear delay differential equation , (E) where and τ(t) ≤ t. We establish a new condition which guarantees that every solution of (E) is either oscillatory or converges to zero. These results improve some known results in the literature. An example is given to illustrate the main results.
A generalized Bernstein approximation theorem
Authors: Duchoň Miloslav 
Published: April 2013

ABSTRACT
The present paper is concerned with some generalizations of Bernstein’s approximation theorem. One of the most elegant and elementary proofs of the classic result, for a function f(x) defined on the closed interval [0, 1], uses the Bernstein’s polynomials of f,

We shall concern the m-dimensional generalization of the Bernstein’s polynomials and the Bernstein’s approximation theorem by taking an (m−1)-dimensional simplex in cube [0, 1]m. This is motivated by the fact that in the field of mathematical biology naturally arouse dynamic systems determined by quadratic mappings of “standard” (m − 1)-dimensional simplex to self. The last condition guarantees saving of the fundamental simplex. Then there are surveyed some other the m-dimensional generalizations of the Bern- stein’s polynomials and the Bernstein’s approximation theorem.

Published: April 2013

ABSTRACT
We introduce the Weibull distributions in presence of cure fraction, censored data and covariates. Two models are explored in this paper: mixture and non-mixture models. Inferences for the proposed models are obtained under the Bayesian approach, using standard MCMC (Markov Chain Monte Carlo) methods. An illustration of the proposed methodology is given considering a life- time data set.
Chaos and stability in some random dynamical systems
Authors: Janková Katarína 
Published: April 2013

ABSTRACT
Nonchaotic behavior in the sense of Li and Yorke chaos in discrete dynamical systems generated by a continuous selfmapping of a real compact inter- val means that every trajectory can be approximated by a periodic one. Stability of this behavior was analyzed also for dynamical systems with small random perturbations. In this paper we study similar properties for nonautonomous periodic dynamical systems with random perturbations and for random dynamical systems generated by two continuous maps and their perturbations.

On Pseudo-Random Oracles
Authors: Rjaško Michal 
Published: April 2013

ABSTRACT
Many cryptographic systems which involve hash functions have proof of their security in a so called random oracle model. Behavior of hash functions used in such cryptographic systems should be as close as possible to the behavior of a random function. There are several properties of hash functions dealing with a random behavior. A hash function is pseudo-random oracle if it is indifferentiable from a random oracle. However, it is well known that hash functions based on the popular Merkle-Damg˚ard domain extension transform do not satisfy the pseudo-random oracle property. On the other hand no attack is known for many concrete applications utilizing Merkle-Damg˚ard hash functions. Hence, a weakened notion called public-use pseudo random oracle was introduced. The property can be met by the Merkle-Damg˚ard construction and is sufficient for several important applications. A hash function is public use pseudo-random oracle if it is indifferentiable from a random oracle with public messages (i.e., all messages hashed so far are available to all parties). This is the case of most hash based signature schemes.
In this paper we analyze relationship between the property pseudo-random oracle and its variant public image pseudo-random oracle. Roughly, a hash function is public image pseudo-random oracle if it is indifferentiable from a random oracle with public images (i.e., all images of messages hashed so far are available to all parties, messages are kept secret). We prove that the properties are equivalent.

Abstract
Background: Endothelial dysfunction is increasingly recognized as an important early feature of vascular disease. As the damage to endothelium is a key underlying factor in the development and progression of atherosclerotic processes, markers of endothelial abnormalities have been sought. Increased expression of cell adhesion molecules (CA Ms) on the vascular endothelium has been postulated to play a significant role in atherogenesis. Both in vitro and in vivo studies have suggested that different risk factors of atherosclerosis may increase expression of CA Ms. The elevated level of soluble forms of CA Ms in circulation is associated with a higher risk to future cardiovascular events in subjects predisposed to atherosclerosis.
Objective: To determine the reference range for serum concentration of soluble cell adhesion molecules - sICA M-1, sVCA M-1, sE-selectin, sP-selectin.
Materia l and methods: We studied 110 healthy people of Bulgarian nationality aged 18-65. The selection criteria for the reference group were made in accordance with the requirements of the International Federation of Clinical Chemistry (IFCC ). Serum concentrations of CA Ms were analysed by means of EL ISA assay.
Results: The results are presented as central 95% interval and 0.90 confidence interval of the reference range. Reference ranges were determined for sICA M-1 (128.9 - 347.48 ng/ml), sVCA M-1 (170.42 - 478.36 ng/ml), sE-selectin (9.15 - 65.19 ng/ml) and sP-selectin (101.86 - 209.7 ng/ml). As we found no sex-related differences in the CA Ms concentrations (p > 0.05) there needed to be no separate reference intervals for men and women. The single-factor dispersion analysis we used in analysing the effect of age found no agerelated dependence (p > 0.05, F = 1.038) for the serum CA M concentrations in the 18-65 age range, which means that it is not necessary to establish reference intervals for smaller age ranges in this age group.
Conclusion: The reference ranges for sICA M-1, sVCA M-1, sE-selectin, sP-selectin computed in accordance with the results distribution can be used as baseline criteria in clinical laboratory studies.
Correction of paralytic lagophthalmos
Authors: Anastassov George E. , Khater Regina H. , Anastassov Yourii K. 
Published: April 2013

ABSTRACT
INTRODUCTION: Bell’s palsy causes lagophthalmos of the involved eyelids. Secondary to the atonicity of the eyelids, xerophthalmia, conjunctivitis and epiphora develops. There are dynamic (muscle transfers) and static (gold weights, tarsorrhaphy) approaches to alleviate these problems.
The GOALS of this study are to present a technical note for a surgical method for lengthening the retracted upper eyelid with autogenous temporalis fascia and elevation of the lower eyelid with transplantation of autogenous morselized conchal cartilage graft via standard blepharoplasty incisions.
MATERIAL AND METHODS: The proposed technique is illustrated in details with an example of a patient with paralytic lagophtalmos.
The 4 years follow up of the case operated by this technique shows a stable occlusion of the eyelids with a lowering of the upper eyelid and elevation of the lower eyelid margin.
CONCLUSION: If the paralysis is complete this technique will not accomplish adequate relieve of symptoms. In this cases re-animation of the eyelids with either temporalis muscle transfers or free micro neurovascular muscle transfers are indicated.
