Second order triangular number
Opis:
Let G=(V,E) be a graph with p vertices and q edges. A second order triangular graceful labeling of a graph G is an one to one function φ:V(G)→{0,1,2,…,B_q} where B_q is the qth second order triangular number, ie., B_q=1/6 q(q+1)(2q+1), that induces a bijection φ^*:E(G)→{B_1,B_2,…,B_q} of the edges of G defined by φ^* (uv) =|φ(u)-φ(v)| ∀ e=uv ∈E(G). A graph which admits such labeling is called a second order triangular graceful graph. In this paper, we introduce second order triangular graceful labeling and we prove that star, subdivision of star, nK_1,3, nK_2, bistar, path, comb, coconut tree, shrub and Y-tree are second order triangular graceful graphs.

Opis:
An approach to nonlinear constrained mathematical programming problems which makes use of a second order derivative is presented. By using a second order modified objective function method, a modified optimization problem associated with a primal mathematical programming problem is constructed. This auxiliary optimization problem involves a second order approximation of an objective function constituting the primal mathematical programming problem. The equivalence between the original mathematical programming problem and its associated modified optimization problem is established under second order convexity assumption. Several practical O.R. applications show that our method is efficient. Further, an iterative algorithm based on this approach for solving the considered nonlinear mathematical programming problem is given for the case when the functions constituting the problem are second order convex. The convergence theorems for the presented algorithm are established.

Opis:
This study examines evidence for the hypothesis (e.g., Muñoz, 2006) that an early starting age is not necessarily more beneficial to the successful learning of L2 inflectional morphology in strictly formal instructional settings. The present author investigated the quantitative and qualitative differences in the production and reception of 5 selected inflectional morphemes in English written performance and competence tasks by 100 early classroom learners and 100 late classroom learners of the same age. While an earlier age of first exposure and a longer instructional period was not associated with higher accuracy scores, the findings suggest distinct patterns in the productive and receptive knowledge abilities of inflectional morphology; the late classroom learners’ superiority seems to be rooted in their greater reliance upon memory-based item-by-item associative learning, as they are significantly stronger on tasks that might cause semantic difficulties, whereas the early classroom learners are marginally better on pattern-based processes for certain morphemes. This finding possibly supports Ullman’s (2005) proposal that, as procedural memory declines with age, older starters have difficulty in discovering regularities in the input and thus over-rely on the declarative memory system in L2 learning.

Opis:
In this paper, we introduce new classes of nonsmooth second-order cone-convex functions and respective generalizations in terms of first and second-order directional derivative. These classes encapsulate several already existing classes of cone-convex functions and their weaker variants. Second-order KKT type sufficient optimality conditions and duality results for a nonsmooth vector optimization problem are proved using these functions. The results have been supported by examples.

Opis:
Foreign language teachers’ language competence is one of the key factors contributingto the success of instruction as it ensures the provision of a good model of the target language,enables teachers to address the problems learners encounter, and makes teaching more creative. For this reason, improving this facet of a teacher’s expertise is indispensible in in-service teacher training, either in the form of stand-alone courses or modules incorporated into more comprehensive teacher education programs. The main aim of the present paper is to emphasize the importance of language teachers’ proficiency in the language they teach, describe its dimensions, presentthe possible goals of in-service teacher education in this area, and discuss issues involved inconducting and organizing training of this kind.

Opis:
In recent years increased attention has been given in applied linguistics to the learning processes of various groups of special needs (SN) students, especially to those whose achievement is impeded by dyslexia or other learning difficulties. However, students with sensory impairment, particularly those who are Deaf or severely hard of hearing (HOH), seem to have remained on the periphery of second language acquisition (SLA) research although they constitute a highly interesting group both from a linguistic as well as a cultural point of view. Since the best approach to understanding how this special minority handles foreign language learning is by first exploring their so-called individual differences, a nationwide research project was launched in Hungary to investigate students’ language learning beliefs, motivation, strategy use and motivated learning behavior. As part of that project, the present paper intends to detail how self-related concepts of hearing impaired students at eight different SN schools  an be described. In order to gain an in-depth understanding, a mixed-method research design was employed. First, a barrier-free instrument was used to measure learner variables among 105 14-19-year-old Deaf and HOH learners. Then 31 individual interviews were conducted with selected students using maximum variety sampling. The quantitative data indicate that Deaf and HOH (D/HH) learners lack pronounced, well-developed and detailed future ideal L2 selves and corresponding visions to guide their learning. Another important finding is the paramount importance of language learning experience for our D/HH participants. Based on the analysis of the qualitative data, we can conclude that students’ language learning experiences are largely shaped by the choice of language used as the medium of education, the intensity and content of the English classes as well as how far students internalize extrinsic motives.

Artykuł dotyczy kształcenia językowego seniorów jako kategorii wiekowej zyskującej na znaczeniu w dobie starzejących się społeczeństw. Wielowymiarowa edukacja ustawiczna, obejmująca także kursy języka obcego, jest ważnym aspektem zapewniania aktywnej starości umożliwiającej czynne uczestnictwo w życiu społecznym sensu largo. W artykule omówiono specyfikę akwizycji języka w wieku seniorskim, przedstawiono dane statystyczne dotyczące kompetencji językowych osób po 65. roku życia w oparciu o wyniki badań ogólnopolskich, zaprezentowano typologię form kształcenia językowego osób starszych oraz scharakteryzowano pracę z seniorami z perspektywy glottodydaktycznej na podstawie doświadczeń z uczestnikami kursu włoskiego na Uniwersytecie Trzeciego Wieku w Akademii Wychowania Fizycznego w Warszawie.
The paper examines language education of senior learners, whose enrolment in language courses – considering the phenomenon of population aging – is becoming more and more noticeable. A well-organized process of lifelong learning, including also language education, enables senior citizens to fully and actively participate in the rapidly changing social life. The aim of the paper is to describe language acquisition in this age group; to present statistical data about Polish learners over 65 and a typology of educational forms addressed to seniors; and, last but not least, to analyze the glottodidactic process based on participants of the Italian course at the University of the Third Age at the Józef Piłsudski University of Physical Education in Warsaw.

Opis:
After Poland regained its independence in 1918, Polish people started rebuilding civil hospital network. Bad health conditions of the society and spreading epidemics forced people to undertake the immediate actions. In Bialystok province in the twenties of the twentieth century there were 47 hospitals and among them 18 were epidemic. In following years there appeared the tendency of reducing the amount of hospital institutions. This situation was influenced by the Great Depression in the thirties of the twentieth century. Very often smaller hospitals were merged into one large institution which had several departments with specialized medical staff. The causes of such actions were medical reasons. In the interwar years, in the area of Bialystok province there were also two specialized institutions established. They used innovative ways of treating. It was the Hospital for Mentally and Nervously Ill in Choroszcz and the Public Institute for Nervously Exhausted in Świack.

The aim of the study was to evaluate the effect of four fertigation levels (25, 50, 75 and 100% of fertilizer dose, 240:100:200 kg N:P:K ha-1) and to compare with conventional practices (CP). The fertigation levels F1 25% of total fertilizer (60:25:50 kg N:P:K ha-1) treatments, F2 treatment is 50% of total fertilizer (120:50:100 kg N:P:K ha-1), F3 treatment is 75% of total fertilizer (180:75:150 kg N:P:K ha-1), F4 treatment is 100% of total fertilizer (240:100:200 kg N:P:K ha-1). The experiment was conducted during 2012 summer (from 20 June to 15 September) under the field conditions in the Menzilat soil series (Typic Xerofluvents) which is located in the East Mediterranean coastal part of Turkey. The experiment was designed as a completely randomized-block with three replications. The maize plant (Zea mays L.) was sown as second crop following with wheat cultivation. The maize yield was higher in F3 fertigation level treatment (12.47 Mg ha-1) compared to the other treatments. Lowest yield was recorded in F2 (8.45 Mg ha-1) treatment. The results shown that the half of the fertilizer application with conventional practices and the other half with fertigation are more efficient under Menzilat soil series conditions. For future, it is important to see the long term effect of fertigation on soil nutrients dynamic under the Mediterranean soil conditions.

Opis:
Ulrich Beck is a famous German sociologist who has examined the concepts of risk society and the second modernity. Both terms were described by Beck as opposite to industrial society and class society. Recently, Dean Curran has attempted to overcome this opposition, and reconcile hermeneutics of classes and the risk society. This article examines the exchange of arguments between Ulrich Beck and Dean Curran and treats this exchange as a pretext to systematically identify those parts of the theory of risk society that cannot be reconciled with class theory. We examine how Marxian and Weberian theories of classes can effectively explain the phenomenon of second modernity.
