Authors: Singh B. P.
Published: January 2018

This paper examines the level of stress among senior secondary school students and stress managing strategies to overcome stress. Manage appropriate level of stress among students in order to make him constructive and productive citizen of the country. The main objectives were to find out the stress level among different streams of students as well as bring to light measures to counteract the effect of stress in students. A quantitative method was used in gathering and analyzing the data. For this purpose, Singh’s personal stress sources inventory (SPSSI) was distributed among students of different streams to get mean, S.D. and C.R. values. The results obtained show the medium level of stress among different streams of students. Factors responsible for stress are school environment, physical changes, relationship and family conditions. Major findings are : (i) no significant difference in stress level of male and female students of different streams (ii) significant difference in stress level of male students of different streams. (iii) significant difference exists in stress level of female students of different streams. (iv) urban students have more stress level than rural students. (v) students studying in private school experience more stress level than government school students. Stress can be managed by enough sleep, creative games, meditation, yoga, spiritual talk, continuous monitoring the stress level, creating conducing teaching learning environment at school as well as at home and developing good relationship among peers.
The Silence of Nature in Joseph Conrad’s Heart of Darkness: An Ecocritical Study
Authors: Panigrahi Sambit
Published: January 2018

Nature’s passivity in modern man’s discourse has been the area of focus in Ecocriticism. Ecocritics do believe that Nature has lost its vibrancy and vitality in the realm of modern man’s exclusively anthropocentric culture. Such ‘otherization’ of Nature has its roots in the Western philosophical and discursive practices. The Enlightenment philosophy has been instrumental in taking the dehumanization of Nature to a new low in the sense that it sees Nature as an inert, dull and dispirited entity that has its existence only for the material benefit of man. This kind of an attitude is clearly seen in the way the colonizing people in Conrad’s fiction dehumanize Nature and delineate it as a dull and lifeless entity. Based on these precepts this article intends to reread Conrad’s fiction from an ecocritical perspective and thus desires to expose the mechanism through which the human assumes for itself a central position in the universal scheme of things and relegates Nature to the realms o silence and instrumentality.

Published: January 2018

Purpose: This study aims to predict the incidence of dengue hemorrhagic fever using meteorological data such as rainfall, rainy days, air temperature, humidity, and dengue hemorrhagic fever surveillance data by month in Northern Yogyakarta Municipality (Climatic Zone 138) through 2010-2016.Method: It was descriptive research used a predictive design with temporal approach. This research processed secondary data of DHF incidence from Yogyakarta Municipality Health Office and climate variable from Meteorology Climatology and Geophysics Agency (BMKG) Yogyakarta from 2010 to 2016. Data were analyzed univariat and presented in frequency distribution, bivariate analysis was performed using correlation (Pearson/Spearman), and multivariate analysis to get prediction model was done using Poisson regression, negative binomial regression, and generalized poisson regression.Results: DHF incidence in Northern Yogyakarta Municipality (Climatic Zone 138) was associated with meteorological factors in the same month up to 3 months earlier. Predictors of DHF case were dengue incidence of previous month, rainfall 2 months earlier, current temperature, and relative humidity of the previous month.Conclusion: The best prediction model of DHF incidence in Northern Yogyakarta Municipality (Climatic Zone 138) was a combination of surveillance and meteorological data. It was necessary to develop an awareness system of DHF incidence with meteorological database and surveillance in order to control the incidence of DHF in Yogyakarta Municipality

Authors: Pigoń Katarzyna , Nowak-Radzik Edyta , Młyńczak Tomasz , Banasik Grzegorz , Nowalany-Kozielska Ewa , Tomasik Andrzej
Published: January 2018

Aim:
Study was aimed to assess the real-world costs of manual thrombectomy (MT) in selected ST-segment elevation myocardial infarction patients with intracoronary thrombus (IT).
Methods:
Study group (IT+) comprised 51 patients with MT applied and control group (IT-) comprised 56 patients without IT who underwent angioplasty alone. Costs comprised hospital care and cost of disposable materials used during primary angioplasty.
Results:
Complex management of patients with IT is more expensive, though allows to achieve clinical outcomes comparable to low-risk ST-segment elevation myocardial infarction patients without IT.
Conclusion:
A complex pharmaco-interventional strategy, with glycoprotein IIB/IIIA inhibitor and MT, though more expensive, may prove cost-effective.

La evaluación, los ”rankings” internacionales y la moda
Authors: RUSSELL BARNARD JANE M.
Published: January 2018

El mundo en que hoy vivimos se caracteriza por ser altamente competitivo. La preocupación por lograr un buen posicionamiento con respecto a nuestros pares, no es ajena al mundo académico. Con la publicación en 1975 de las primeras listas de los factores de impacto de las revistas científicas de corriente principal por el Institute for Scientific Information, ISI de Filadelfia, el concepto de los “rankings” llegó para quedarse al campo de la Bibliotecología y la Información como una de las formas de ubicar publicaciones en el contexto global. Alcanzar un alto factor de impacto y estar entre las primeras posiciones dentro de su propia categoría temática, permite a una revista académica atraer la atención de más autores y trabajos de calidad, incrementar el conjunto de manuscritos enviados para su publicación y mejorar la selección de éstos como una manerade elevar la calidad de sus artículos y las oportunidades para que éstos sean citados.

A relação entre Hebreus e as práticas da Sinagoga: um estudo sobre o pano de fundo conceitual de Hebreus
Authors: Rodrigues Adriani Milli , Vasconcelos André Luiz
Published: January 2018

O presente artigo tem como objetivo trazer a relação entre a epístola de Hebreus e as práticas da sinagoga para a discussão a respeito do pano de fundo conceitual desta epístola. Para que isto fosse possível, fez-se necessário realizar uma breve análise das duas principais propostas na literatura contemporânea: o médio-platonismo de Filo e o judaísmo palestino de Qumran. Tendo constatado que o Sitz im Leben de Hebreus é uma homilia pregada na sinagoga e que o autor de Hebreus valeu-se de métodos de exegese rabínica, concluiu-se que a prática da sinagoga fazia parte da imagética do autor de Hebreus. Com base nisso, é então sugerido que este fato seja levado em consideração no debate acerca de seu respectivo contexto intelectual.
A autoria de Hebreus: a sobrevida acadêmica da Hipótese Paulina
Authors: Malheiros Isaac
Published: January 2018

A autoria de Hebreus provocou um debate que começou nos primeiros anos da igreja cristã, diminuiu entre os séculos V e XV, renasceu durante a Reforma do século XVI, e perdura até hoje. O objetivo central desse artigo é, através de uma pesquisa bibliográfica, demonstrar que a antiga sugestão de que Paulo é o autor de Hebreus não está completamente descartada, tendo recentemente ganhado renovada sobrevida na academia. Este artigo não fará uma análise pormenorizada dos argumentos favoráveis ou contrários à autoria paulina, mas uma exposição histórica dessa proposta, com ênfase em suas defesas mais recentes.

Translating Coetzee: a panel discussion
Authors: Hollington Michael
Published: January 2018

With Cristobal Perez Barra (Chile), Peter Bergsma (The Netherlands), Reinhild Böhnke (Germany), Miguel Temprano Garcia (Spain) and Jinghui Wang (China).It was my privilege to be asked to chair a panel on translating J.M. Coetzee at the very end of the ‘Reading Coetzee’s Women’ Conference held at the Monash Campus in Prato, Italy from 27 to 29 September 2016, and now, to present an account of that occasion which contains versions, either of the papers presented at the meeting itself by three of the four invited participants who were able to attend, or submitted to me by two others who could not.The text of the contributions has been very lightly edited by me on the few occasions where it seemed this might help to convey the writer’s meaning with maximum clarity in idiomatic contemporary English, and then submitted to the author for approval. In the same way a draft of the following essay as a whole has been submitted to all the participants for comment or suggested amendment. The result, I hope, is that this essay can be considered in large measure as collaborative work – or, indeed, a conversation.Inevitably, the range of languages covered here is very partial, and indeed, a matter of chance. Before the conference began we were worried that, as a result of participants accepting and then finding themselves forced to withdraw and send in messages to be read on their behalf, real live translators would be rather thin on the ground, reduced to stalwart representatives from Holland and Italy. But we were in luck, discovering as conference delegates arrived that among them were two more Coetzee translators. Furthermore, these were of special interest: representing China and South America respectively, they would enable us to move out beyond the Eurocentric focus originally envisaged. Since both of them kindly agreed to take part at very short notice, we could go a little further than we had hoped, offering a glimpse of the world reception of a writer who, unquestionably, already belongs in his lifetime to Goethean Weltliteratur.

Diante desse contexto, ofertou-se um curso de formação continuada para professores deste nível de ensino objetivando explorar e discutir atividades teóricas e práticas com o propósito de os professores as utilizarem em suas aulas. O curso teve duração de quarenta horas e os docentes foram instigados a desenvolver as atividades problematizadas durante os encontros, com seus alunos. Os dados foram coletados por meio de gravações realizadas durante os encontros, bem como de um relatório entregue, no final do curso, pelos participantes o qual deveria apresentar as atividades desenvolvidas, reação dos alunos e uma avaliação das situações propostas. Os resultados apontaram que: a) os participantes utilizaram as práticas problematizadas durante o curso; b) as atividades propostas foram significativas tanto para os professores participantes, quanto para seus alunos; c) a formação continuada possibilitou melhoria na qualidade de ensino, pois motivou o docente a refletir sobre sua prática e reestruturar suas metodologias.
DETERMINANTS OF MILK PRODUCTION DIVERSITY IN THE MACROREGIONS OF THE EUROPEAN UNION
Authors: Guth Marta
Published: January 2018

The paper aims to distinguish economic determinants of milk production in clusters of FADN regions with farms similar to each other in terms of total utilized agricultural area, number of milk cows and annual milk yield in the light of selected taxonomic methods, i.e. cluster and factor analysis. Observed by the analysis of standard deviations and Gini coefficients, increasing diversity of the majority of characteristics of FADN dairy farms (in 2011 relative to 2004) led to think that production in farms similar to each other in terms of the number of dairy cows, the amount of utilized agricultural area and an annual milk yield can be conditioned by similar determinants, which may differ depending on the membership in a particular group. Classification of groups of regions with similar dairy farms was made using cluster analysis, and the diversification of production determinants was illustrated on the basis of factor analysis in the distinguished clusters. In order to determine the variability distinguished determinants analysis was performed for two research periods (years 2011 and 2013).

Authors: Foryś Iwona , Tarczyńska-Łuniewska Małgorzata
Published: January 2018

Funds investing in the Polish real estate market have been functioning since 2004, but they have lived through both the times of the 2006–2008 boom and the times of the 2009–2014 crisis. The first close-end funds were established in 2004 and were originally intended to close down after eight years. However, their results did not guarantee the return expected by investors. The purpose of the study is to evaluate the performance of the Polish investment funds operating on a young, ten-year-old market in the context of the experience of mature markets with a long history of funds investing in real estate. The paper presents the cause and effect analysis of the impact of macroeconomic factors on the funds’ results as well as of behavioral factors contributing to low interest in the real estate investments with the participation of Polish investment funds operating on the Polish real estate market.
FOOD PRODUCERS’ COMPETITIVENESS GAP IN POLAND ON THE EUROPEAN UNION MARKET
Authors: Juchniewicz Małgorzata
Published: January 2018

This article presents the gap in potential and competitive position of food producers in Poland as compared to selected the European Union countries. The timeframe of research covered the years 2005–2015. The conducted analyses indicate the positive phenomenon of a decreasing but, at the same time, a very clear distance between the competitive potential of food producers in Poland and European leaders. The productivity level of particular production factors indicates, at the same time, the fact that the least beneficial situation was recorded in the case of the productivity of human work. A definitely smaller competitive gap was present at the level of the capital’s productivity. The decreasing competitive gaps were also observed with regard to particular partial measures of the competitive position. The nearly double increase in the share of Polish food producers in intra-Community export was particularly beneficial. This was not reflected in a significant change of the competitive position of domestic food producers on the EU market with the low output level of this index.
THE BEGINNINGS AND DEVELOPMENT OF AGRICULTURAL ADVISORY SERVICES IN POLAND
Authors: Kania Józef
Published: January 2018

The main objective of this article is to present the development of agricultural advisory services in Poland from its beginnings on the Polish lands, until the entry of our country into the European Union (1 May 2004). The data was obtained from a review of literature, published mainly in Polish, hence, not known in English publications and originates from the author’s research carried out in the framework of research grant. The study used a descriptive method and documents the history of agricultural extension dating back to the mid-19th century. In the interwar period (1918–1939), advisory services were carried out by the newly established agricultural chambers, and after World War II, after their liquidation, by state system of agricultural advisory services, which was subject to many changes in the organizational structure and objectives pursued. In the first period of transition of agriculture to a free market economy, the author emphasized the big role of the Polish/American Extension Project for the reorganization of Polish advisory and improvement of skills of our advisers.
INVESTMENT IN HIGHER EDUCATION VERSUS ECONOMIC GROWTH – A PROPOSAL FOR THE DECOMPOSITION OF THE MRW MODEL FOR POLAND
Authors: Kowalska Iwona , Banduła Bartosz
Published: January 2018

Higher education has become an increasingly knowledge-based sector of the present-day economy. The state faces the issues of financing higher education and assessing the effects of investment in the sector of higher education. The aim of this article is to determine the impact of investment expenditure on higher education (including the resources from the EU funds) on Poland’s economic growth as measured by the GDP growth rate. The research hypothesis of the article is that the economic growth that is caused by investment in higher education with the contribution of the EU funds results in a higher GDP growth than in the case when there is no access to such resources. The results of the research indicate that increased investment in higher education, which was the result of the availability of the EU structural funds, influenced the increase in human capital in Poland and raised its impact on the GDP growth rate.
THE DETERMINANTS OF HOUSEHOLD SAVINGS IN POLAND
Authors: Szopiński Tomasz
Published: January 2018

The relevant literature provides an array of factors determining the propensity of households to save. There is no unanimity among researchers as to the direction of statistical relationships among some variables such as, e.g. household income, the place of residence or concerns regarding the worsening of financial circumstances, and a household’s propensity to save. The aim of this article is to verify the statistical relationships between the amount of savings of Polish households and their attributes, such as: income, biological type of the family, and the size of the place of residence. The author of the article analyses the responses provided by Polish households with regard to the size of their savings measured as a multiple of their income. The data under analysis were collected during a panel study Diagnoza społeczna 2015 (ang. Social Diagnosis 2015). Higher earnings were accompanied by higher levels of savings. It was more common for households from bigger cities to have higher earnings. Taking into consideration the biological type of the family, childless marriages and people, who lived alone, declared having the highest savings.
SUSTAINABLE CONSUMPTION OF RURAL AND URBAN HOUSEHOLDS IN POLAND
Authors: Utzig Monika
Published: January 2018

Sustainable consumption is the consumption of goods and services satisfying fundamental needs, increasing life quality, reducing resource use, degradation and pollution along the whole lifecycle of product or service. The aim of the study is to examine whether the consumption of urban households is more sustainable compared to rural ones and to identify directions of changes in this regard. The analysis was realised on the basis of Household Budget Survey conducted by the Central Statistical Office of Poland (CSO) in the span of 2006–2015. The results show that urban and rural households in Poland shift their consumption patterns towards less sustainable as well as urban households’ consumption pattern in some areas is less sustainable that urban ones.
Susceptibility of some cowpea varieties to the seed beetle Callosobruchus maculatus (F.) (Coleoptera: Chrysomelidae)
Authors: Musa Abdulrasak , Adeboye Abiola
Published: January 2018

The study evaluated seven cowpea Vigna unguiculata L. Walp. varieties:
IT89K-568-18, IFE-98-12, IT81P-994, IT89K-288, IT96-660, ?Milk? and ?Drum?
for susceptibility to the seed beetle, Callosobruchus maculatus (F.)
(Coleoptera: Chrysomelidae). Seed samples (100 g) of each variety were
infested with 5 pairs of the seed beetle (1-2 days old) with three
replications at 30?20C and relative humidity of 69-72%. The parameters
evaluated included: number of damaged and undamaged seeds, percentage seed
weight loss, mean number of emerged adults, median developmental period and
susceptibility index. The percentage seed weight loss in IT96-660 was
significantly (p<0.05) higher than in IT89K-568-18, IT89K-288 and ?Milk?. The
mean number of seeds damaged in IFE-98-12 was significantly (p<0.05) higher
than in IT89K-568-18, IT81P-994, IT89K-288, IT96-660 and ?Milk?. The median
developmental period in ?Milk? was significantly (p<0.05) higher than in
IT89K-568-18, IFE-98-12, IT96-660 and ?Drum?. IFE-98-12 and IT89K-568-18 with
susceptibility index of 10.4 and 7.8 were rated highly susceptible and
moderately susceptible, respectively. The number of emerged adults was highly
significant and positively correlated with the percentage seed weight loss.
Results obtained showed that these cowpea varieties were relatively
susceptible to C. maculatus attack in storage suggesting the need for their
proper preservation against the insect.
Effects of spacings and butachlor levels on weed control, growth and yield of NERICA 1 rice (Oryza sativa L. x Oryza glaberrima L.)

Published: January 2018

Poor agronomic practices coupled with herbicide mismanagement influence crop
performance, yield, weed infestation and environmental hazards. Thus, field
experiments were carried out to investigate the effect of spacing and reduced
levels of butachlor on weed control and yield of NERICA 1 rice (Oryza sativa
L. x Oryza glaberrima L). The experiments were conducted in the 2011 rainy
season at the Teaching and Research Farm of the Department of Crop Production
and Horticulture, Modibbo Adama University of Technology, Yola, and Lake
Gerio, Yola in the 2012 dry season. Yola is located between latitude 9o14? N
and longitude 12o28? E in the Northern Guinea Savanna ecological zone of
Nigeria. Treatments consisted of four spacings (20 cm x 20 cm, etc.) and four
butachlor levels (3, 2, 1, and 0 kg ha-1 a.i.). The experiments were laid out
in a split-plot design with spacings assigned to the main plot and butachlor
levels assigned to the sub-plot and were replicated three times. Data were
taken on percentage establishment, number of leaves per plant, general weed
cover, panicle length and grain yield per hectare. Data generated were
subjected to analysis of variance. Means showing a significant F-test were
separated using LSD. Results obtained showed that butachlor at 1 kg ha-1 and
14 cm x 14 cm spacing gave the highest grain yield of 1441 kg ha-1 and
maximum weed control. They are, therefore, recommended for adoption by
farmers in Yola and similar environments.

Published: January 2018

The eight-week feeding trial was conducted to evaluate the nutrient
digestibility and growth performance of broiler chickens fed raw or processed
Senna obtusifolia seed meal (SOSM). Six experimental diets were compounded to
contain 0% SOSM and 20% each of the raw, boiled, soaked, sprouted and
fermented SOSM respectively. Two hundred and sixteen (216) broiler chicks
were randomly allotted to six (6) dietary treatments in a randomised complete
block design with three (3) replicates containing 12 chicks each. Data were
collected on nutrient digestibility, feed intake, weight gain, feed
conversion ratio and mortality. The result of productive performance
indicated that feed intake, weight gain and feed conversion ratio were
significantly (P<0.05) depressed in broiler chickens fed raw, soaked and
sprouted Senna obtusifolia seed meal. However, broiler chickens fed fermented
SOSM showed better (P<0.05) productive performance that was close to those
fed the positive control diet (0% SOSM). The mortality rate did not reveal
any particular trend. However, the low mortality rate recorded in the
different treatments indicated broiler chicken can tolerate up to 20% of
either raw or processed SOSM. Broiler chickens fed raw SOSM recorded lower
values for dry matter (63.06%), crude protein (52.46%), ether extract
(53.88%), crude fibre (30.72%) and nitrogen-free extract (46.11%)
digestibility than those fed the other processed SOSM. The nutrient
digestibility of broiler chickens fed fermented SOSM was significantly
(P<0.05) better followed by those fed boiled Senna obtusifolia seed meal. For
instance, broiler chickens fed fermented Senna obtusifolia seed meal recorded
the highest crude protein and ether extract of 69.91 and 70.03% compared to
the other processing methods. It can be concluded that 20% fermented SOSM can
be incorporated in the diets of broiler chickens with acceptable depreciation
in biological performance. Slightly lower levels of boiled SOSM can be
included in the diet of broiler chickens but the levels should be ascertained
in further studies.

Published: January 2018

3D Finite Element Method simulations were employed in order to describe
tunability properties in anisotropic porous paraelectric structures. The
simulations predicted that properties of a ceramic can be tailored by using
various levels of porosity. Porous Ba0.6Sr0.4TiO3 (BST) ceramics have been
studied in order to investigate the influence of porosity on their functional
properties. The BST ceramics with various porosity levels have been obtained
by solid-state reaction. Lamellar graphite in different concentration of 10,
20 and 35 vol.%was added as sacrificial pore forming agent. The structural,
microstructural, dielectric and tunability properties were investigated. By
comparison with dense BST ceramic, porous samples present a fracture mode
transformation from intragranular to an intergranular fracture and a decrease
of grain size. Lower dielectric constants, low dielectric losses, but higher
values of tunability than in the dense material were obtained in the porous
BST structures as a result of local field inhomogeneity generated by the
presence of air pores-ceramic interfaces.
