Liberating critical pedagogy of Paulo Freire in the scientific production of Nursing 1990-2017
Authors: Garzon Adriana Marcela Monroy , Silva Kênia Lara da , Marques Rita de Cássia
Published: August 2018

ABSTRACT Objective: To analyze the theoretical and methodological application of Paulo Freire’s critical pedagogy in the scientific production of nursing. Method: An integrative review was carried out with consultation of the databases: LILACS, BDENF, MEDLINE, PUDMED and CINHAL. We included studies in the Spanish, English and Portuguese languages, published from 1990 to 2017. Results: A total of 38 articles were analyzed, of which the main concepts adopted were: dialogue/dialogicity, awareness/critical awareness and questioning. Regarding the application of the method, it was noticed the predominance of the adoption of elements such as culture circles, thematic phase and horizontality relation of the nurse with the individuals involved. Conclusion: Nursing has partially appropriated the Freire’s referential. However, it reveals the intentionality of a transformative practice that requires deepening for the implementation of the method in its full.

Published: August 2018

ABSTRACT Objective: to analyze the perceptions of professors and students on academic tutoring. Method: descriptive study with a qualitative approach, carried out at the Magalhães Barata School of Nursing, State University of Pará, Brazil. Twenty-seven professors and 32 students participated in the study. Data were collected through semi-structured and individual interviews, using different scripts for professors and students. For analysis, the technique of content analysis was used. Results: we defined three thematic categories: academic tutoring as a tool for strengthening teaching-learning; academic tutoring as a possibility of intellectual and social transformation; and reflections of academic tutoring in nurses’ training. Final considerations: the teaching-learning process is referred to as a process in which there must be dialogue, and in which professors, students, and tutors learn with each other, breaking the traditional paradigms of unilateral and vertical transfer of content. Academic tutoring stands out as promoter and strengthener of this process.
Caboclos e Orixás no Terreiro: modos de conexão e possibilidades de simbiose
Authors: Rabelo Miriam C. M. , Aragão Ricardo
Published: August 2018

Resumo Entidades brasileiras, donas da terra, caboclos são presença marcante nos candomblés de Salvador, onde são cultuados os orixás, divindades africanas. Neste trabalho, discutimos o modo como eles se conectam no terreiro de candomblé e nos corpos dos adeptos. Procuramos mostrar que essas conexões constituem exemplo de simbiose no contexto do que a filósofa Isabelle Stengers denomina ecologia das práticas: são conexões parciais entre seres que, embora relacionados por interesses comuns, seguem divergindo. Conforme argumentamos, oportunidades de simbiose desenham-se na dinâmica espacial do terreiro e apoiam-se em uma ética sutil que maneja a distância entre termos que se atraem.

Resumen El objetivo de este artículo es sistematizar investigaciones que centran su estudio en la relación entre educación y religión, sea porque refieren a procesos de transmisión intergeneracional en comunidades religiosas, indagan instituciones escolares religiosas o exploran las relaciones entre grupos religiosos, iglesias y la laicidad en el sistema escolar. Para ello, nos basamos en la recopilación de bibliografía disponible en las disciplinas que se han abocado al estudio de estos campos, aún cuando no se propusieran explícitamente analizar sus vinculaciones, considerando principalmente las investigaciones en antropología, pero también en otras ciencias sociales. Partiendo de estos materiales, realizaremos una primera sistematización para reconstruir los ejes que son abordados en las investigaciones, como modo de trazar un marco de análisis que sirva de referencia inicial en cualquier trabajo preocupado por los procesos educativos y las experiencias formativas religiosas de niños y niñas.

ABSTRACT: The objective of this study was to investigate the echocardiographic changes during anesthesia induction in dogs sedated with acepromazine (0.05mg/kg) and butorphanol (0.3mg/kg) (AB). Twenty-four male dogs, with a mean weight of 12.40kg±3.1kg, were randomly assigned to 4 groups (n=6). Fifteen minutes after administering pre-anesthetic medication, anesthesia with diazepam (0.5mg/kg) and etomidate (1mg/kg) (group DE); diazepam (0.5mg/kg) and ketamine (3mg/kg) (group CD); propofol (4mg/kg) (group P); or ketamine (1mg/kg) and propofol (3mg/kg) (group CP) was administered to the 6 dogs in each group. Systolic blood pressure (SBP) was measured and echocardiography was performed immediately prior to the application of the sedation protocol (baseline), 15 minutes after sedation (M1), and immediately after anesthesia induction (M2). No significant differences were observed in SBP and in hemodynamic variables such as cardiac index, shortening fraction, and ejection fraction, between groups at all time points (M0, M1, and M2) evaluated. The SBP was significantly reduced after anesthetic induction in the dogs of the DE and CP groups. It can be concluded that the protocols DE and CP reduce similarly to SPB in dogs medicated with CD and P to SBP remain stable after anesthetic induction. All anesthetic induction protocols maintained a stable IC in premedicated dogs. None of the protocols evaluated promoted significant echocardiographic changes. Furthermore, the ketamine and diazepam combination had a negative impact on myocardial relaxation.

Published: August 2018

ABSTRACT: This study was conducted to evaluate the effect of ractopamine concentrations on swine fat and meat lipid profiles. Ninety finishing barrows, initially weighing 71.9±4.4kg, were distributed in a randomized block design in three ractopamine concentrations (0, 10 and 20ppm) with fifteen replicates of two animals in each. Gas chromatography was used to analyze the lipid profiles of backfat and meat. The inclusion of ractopamine in the diet changed (P<0.05) α-linolenic acid and eicosatrienoic acid concentrations in the backfat but did not affect (P>0.05) any of the other fatty acids or indexes evaluated. In the meat, a significant effect (P<0.05) was observed on nine fatty acids evaluated, with a decrease (P<0.05) in lauric, myristic, and palmitic fatty acids, and an increase (P<0.05) in linoleic, γ-linolenic, dihomo-γ-linolenic, and eicosapentaenoic acid. Ractopamine also affected (P<0.05) the concentration of α-linolenic and arachidonic acid in the meat (P<0.05). The indexes evaluated were also affected (P<0.05). Addition of 10ppm decreased the saturated fatty acid concentration, atherogenic index, thrombogenic index and omega 6: omega 3, while it increased unsaturated and polyunsaturated fatty acids concentrations. Ractopamine addition had less effect on the backfat than on the meat, and the 10ppm level improved the meat lipid profile.

ABSTRACT: The aim of this study was to evaluate the effects of three enteral electrolyte solutions, each with different energy sources, administrated as continuous flow on the physiological parameters and blood count of healthy Holstein heifers. Six Holstein heifers were used in a crossover design. All animals received all three treatments: solution with calcium propionate, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, and 10g of calcium propionate diluted in 1000mL of water (measured osmolarity: 299mOsm/L); solution with glycerol, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, 1g of calcium acetate, and 10mL of glycerol in 1000mL of water (measured osmolarity: 287mOsm/L); solution with propylene glycol, 4g of NaCl, 0.5g of KCl, 0.3g of MgCl2, 1g of calcium acetate, and 15mL of propylene glycol in 1000mL of water (measured osmolarity: 378mOsm/L). Physical evaluations and blood samples were collected immediately before the initiation of fluid therapy, at 3-hour intervals over the 12-hour period of fluid therapy, and 12 hours after the end of fluid therapy. Animals presented no signs of stress or discomfort. All solutions resulted in a significant decrease in erythrocyte concentration, hemoglobin concentration, and hematocrit, without affecting the leukogram. Enteral fluid therapy administered as continuous flow via the naso-ruminal route was well-tolerated by animals with minimal effects on animal welfare, even when administered for 12 hours. This technique is indicated as an alternative route for parenteral maintenance fluid therapy. Electrolyte solutions proposed here were able to significantly expand blood volume.

ABSTRACT: The objective of this study was to determine the prevalence of anti Trypanosoma vivax antibodies and the possible risk factors associated with the infection in cattle in Rio Grande do Norte, Northeastern Brazil, through a cross-sectional epidemiological study, with non-probabilistic convenience sampling. A total of 467 cattle’s serum samples were analyzed by indirect immunofluorescence. Forty-two samples tested positive for Trypanosoma vivax IgG antibodies, corresponding to the prevalence of 9%. Risk factors influencing the occurrence of trypanosomiasis were milk exploration, raising of European breeds, productivity category: lactation cow, purchase of new cattle, foraging habits near ponds and rivers, and the presence of mechanical vectors. So, high prevalence in beef animals (59.5%), females (95.2%), European breed (88.1%), lactating cows (85.7%), pasture at banks of dams and rivers (95.2%), in addition to the presence of mechanical vectors (81%) and acquisition of animals (88.1%), indicates the expansion of trypanosomiasis in Northeastern semi-arid region, and the information obtained may explain the epidemiological factors that determine the occurrence of trypanosomiasis by T. vivax in this region.

RESUMO: Objetivo: Descrever e analisar o absenteísmo dos trabalhadores do Brasil notificados com distúrbios musculoesqueléticos, do período de 2007 a 2012. Métodos: Estudo quantitativo, transversal e descritivo, com dados retrospectivos e secundários. Os registros foram do Sistema de Informação de Agravos de Notificação, que notifica trabalhadores em regime de previdência, bem como os informais. O período do estudo foi de seis anos. As variáveis foram: sociodemográficas, organizacionais do trabalho e específicas do agravo. Resultados: Foram aproximadamente 5 milhões de dias perdidos de trabalho, de 18.611 trabalhadores afastados e notificados com o agravo. Os grupos que mais se destacaram na análise foram os analfabetos, na faixa etária dos 50 aos 59 anos, com carga horária diária de trabalho acima de 6 horas, do grande grupo ocupacional 4, os CID-10 M50 e M51 e os trabalhadores com transtornos mentais. Conclusões: Elevado absenteísmo entre os trabalhadores com distúrbios musculoesqueléticos, analfabetos, idade dos 50 aos 59 anos, trabalhadores de serviços administrativos, CID-10 M51 e trabalhadores com transtornos mentais. Há necessidade de traçar políticas públicas que contemplem o absenteísmo causado pelo agravo, a fim de reduzir a morbidade, bem como os prejuízos socioeconômicos.

Resumo OBJETIVO Analisar as relações entre a presença e a orientação da Atenção Primária à Saúde e as internações por condições sensíveis à atenção primária em um hospital universitário. MÉTODO Estudo seccional com amostra de 197 sujeitos internados no período de março a junho de 2016 na clínica médica de um hospital universitário de Juiz de Fora. A aferição, realizada por meio de entrevistas, utilizou o Primary Health Care Assessment Tool, versão reduzida para adultos, e a lista brasileira de condições sensíveis, editada pelo Ministério da Saúde. RESULTADOS A frequência regular à Atenção Primária esteve associada às internações (RP:2,06), especialmente frente ao baixo desempenho dos atributos de acesso (RP:5,3) e da integralidade (RP:4,7). CONCLUSÃO A baixa orientação dos atributos da Atenção Primária sugere que somente a cobertura deste nível talvez não seja suficiente para reduzir estas internações, mas a forma que ela se organiza e efetiva no nível comunitário.

Published: August 2018

ABSTRACT The netted melon requires special growing conditions, including a protected environment, an adequate staking system and proper water and nutrient management. This study aimed to assess the effect of irrigation levels and silicon doses on the yield and quality of Sunrise hybrid melons, in a greenhouse. A randomized block design was used, with a 5 x 3 factorial scheme and four replications. The first factor consisted of five silicon doses (0 kg ha-1, 50 kg ha-1, 100 kg ha-1, 150 kg ha-1 and 200 kg ha-1) and the second of three irrigation levels (40 %, 70 % and 100 % of the ETc). The results demonstrated that the applied irrigation levels and silicon doses have no influence on the yield traits of melon plants. The irrigation level corresponding to 100 % of the ETc promotes higher values for soluble solids (9.86 ºBrix) and maturation index (114.9) on fruits. The increase of silicon doses up to 200 kg ha-1 also increases the maturation index in the treatment with the greatest irrigation level and reduces this index at the shallowest level applied.

Published: August 2018

ABSTRACT Complications are rare in pediatric cases of idiopathic nephrotic syndrome (NS). Thromboembolism ranks among the most uncommon and difficult complications to diagnose, particularly in the first episode of NS, since clinical signs might be unspecific. This report describes the case of a 5-year-old girl with NS for the first time presenting with severe hypoalbuminemia (< 2g/dL). The patient responded poorly to therapy with corticosteroids. On day 8 of hospitalization she started having headaches and vomiting; she did not present hemodynamic alterations, fever or exanthems, and her neurological parameters were normal. The patient was suspected for intracranial hypertension, and computed tomography scans revealed she had cerebral venous sinus thrombosis (CVST). She was started on anticoagulants and showed clinical signs of improvement. The patient had no evident prothrombotic risk factors. She had three other episodes since she was diagnosed, one in which her plasma antithrombin level was low. Although antithrombin levels were normal in her first episode, she was tested after the resolution of proteinuria. The low levels of antithrombin seen in the first recurrence might have mirrored the initial drop in plasma antithrombin levels, an idea supported by the severe hypoalbuminemia she had when diagnosed. This severe manifestation of acquired thrombophilia might be in the origin of CVST. This report presents a rare case of thromboembolic complication in a pediatric patient with NS. The patient progressed well since she was started on anticoagulants. Although she did not present any evident risk factors at first, the development of her case indicated that severe acquired thrombophilia might have worked as the pathophysiological mechanism leading to CVST.

Por fim, a ideia da cultura digital, correlacionada à formação, denota movimento contrário à polarização do presencial, não presencial, a distância e/ou on-line, convergindo para a ideia de hibridizações.
Potencial de índices urbanísticos como indicadores da qualidade térmica do ambiente urbano
Authors: Vasconcelos Juliano Souza , Souza Léa Cristina Lucas de
Published: August 2018

RESUMO A qualidade térmica do ambiente urbano é um dos problemas enfrentados pelas cidades atualmente. A forma de ocupação urbana altera o balanço de energia nas cidades, provocando frequentemente um aquecimento do ar nas camadas intraurbanas e criando microclimas variados. No entanto, mapear os microclimas urbanos possibilitando apoio à tomada de decisões de planejamento urbano é uma tarefa complexa e de longo prazo. Procurando demonstrar as potencialidades térmicas oferecidas por alguns índices urbanísticos usualmente aplicados por órgãos decisores, este artigo buscou verificar a influência dos coeficientes de ocupação, de aproveitamento e de cobertura vegetal sobre a temperatura do ar em microclimas urbanos. Em uma fração urbana de ocupação consolidada, foram realizadas medições em campo, que serviram de base para a validação de um modelo computacional de simulação do ambiente térmico urbano. Posteriormente foram feitas simulações com diferentes índices urbanísticos e desenvolvidos mapas térmicos. Os resultados apontaram que os coeficientes estudados devem ser mais explorados termicamente, principalmente se considerado o coeficiente de cobertura vegetal, cuja alteração de valores pode levar a diferenças mais significativas na temperatura do ar.

Authors: Ferreira Thays Santos , Barbassa Ademir Paceli , Moruzzi Rodrigo Braga
Published: August 2018

RESUMO O objetivo deste trabalho foi avaliar uma nova concepção de poço de infiltração como técnica de controle de drenagem pluvial na fonte. Esse poço, denominado P-GHidro, possui furos na parede dos anéis de concreto, camada de brita externa aos anéis para melhorar a distribuição de água, pré-filtro de geotêxtil na tampa e filtros adicionais no fundo e na lateral, entre a brita e o solo. Usou-se como referência o poço de infiltração comumente empregado em São Carlos, São Paulo (P-SC), cuja construção foi realizada com anéis de concreto justapostos ao solo sem furos laterais e sem pré-filtro. Foram realizados seis ensaios de chuvas simuladas para cada poço de infiltração. Os dados experimentais de vazão de água infiltrada foram modelados pelo método de Puls. A condutividade hidráulica, constante ou variada, foi empregada como parâmetro de calibração do modelo aos dados experimentais; o ajuste foi avaliado por meio dos coeficientes de determinação (R2) e de Nash-Sutcliffe (NS). O P-GHidro apresentou melhor desempenho na infiltração de água pluvial, com volume armazenado 25% menor e tempos de esvaziamento 4% menores que os do P-SC. A modelagem apresentou boa representatividade dos dados experimentais para condutividade hidráulica constante (média de R2 de 0,92 e de NS de 0,56) e melhor ainda para condutividade hidráulica variada (média de R2 de 0,97 e de NS de 0,97).

Authors: GÜZEL Kudret , ALTUNCU Ekrem , FİDAN Sinan
Published: August 2018

Flame spray technology is basic member of the thermal spray
coating family. Higher cost-effective coatings can be produced at higher speeds
with new flame spray equipments which developed in recent years. The Flexicord flame
spray method developed in this direction offers many advantages. A wide variety
of ceramic coatings can be deposited on metallic surfaces with this spray
methods in the face of wear-induced problems. In this study, solid particle
erosion rates and wear behaviors of different oxide (Al2O3,
MgO-Zr2O3, Al2O3-MgO
based coatings have been studied comparatively with respect to ASTM G76 standard.
Spinel based coatings between the oxide based coatings exhibited superior wear
resistance and significantly lower mass loss than the others. Due to the
fragile nature of the ceramic coatings, the erosive wear rate is increased by
crack growth formation related with the porosity of coating. Due to the
accelerated solid particle impacting at high impact angles, wear rate is
highest.

Dental erosion is a high prevalence condition characterized by the loss of dental substance due to chemical agents. It can also be associated with physical wear, affecting function and aesthetics. Ceramic veneers can provide effective solutions to patients affected by erosive disorders, by means of an indirect approach and minimal intervention. Recent advances in cementation techniques and ceramic materials have allowed their use in reduced thicknesses, known as "dental contact lenses" or "ultra-thin veneers". They contribute significantly to the preservation of the dental structures, having excellent mechanical properties and providing satisfactory aesthetic solutions. Their manufacture requires rigorous planning and the use of three-dimensional models or mock ups in order to preview the final outcome. Case: The aim of this report is to communicate the use of this technique for the treatment and successful 12-months follow-up of a patient affected by dental erosion of the maxillary central incisors. Special interest was placed on direct mock-up, which is a simple technique not requiring laboratory steps. Luting of the lithium disilicate veneers was carried out with a light-curing resin cement and try-in pastes, yielding a very satisfactory result. Conclusion: Diagnosis and early treatment of this disorder allows the application of conservative techniques, such as ultra-thin veneers, which are seen as a promising alternative treatment to full coverage restorations and traditional ceramic veneers.

Objective: To compare the gene expression levels of collagen type I alpha 2 (COL1A2) in children with and without dental fluorosis. Methods: Cross-sectional study involving 92 children between 5 and 12 years of age. Socio-demographic characteristics, the presence of dental fluorosis by means of the Thylstrup-Fejerskov index, and gene expression analysis of COL1A2 in peripheral blood samples by reverse transcription polymerase chain reaction (RT-PCR) assays, were described. For the descriptive analysis, measures of central tendency, dispersion and proportions were used. Differences between the groups (p<0.05) were established by the Student t-test. Results: Mean age was 8.6 (SD=1.9) years, 51.1% were female; 54 children were diagnosed with fluorosis and 38 without fluorosis; prevalence of dental fluorosis was 58.7% (95% CI: 48.4% -68.9%). Gene expression of COL1A2 was statistically significantly lower (p<0.05) in the participants with dental fluorosis. Conclusion: There are differences in the expression levels of the COL1A2 gene among the population under study. Therefore, COL1A2 may be potentially involved in the development of dental fluorosis

Information Technology (IT) is a buzzword in the present economic scenario. It is a tool to build a digital global economy. Thus, organizations worldwide are increasingly introducing various technological changes in their operations. The Indian Postal Department now renamed as India Post is a recent example in this regard. Although IT is beneficial to an organization, its adoption and usage puts the employees in a continuous refinement process. This may trigger different kinds of reactions from the employees towards IT use in their organization. Hence, the study has been an endeavour to identify the factors that significantly have a bearing on the employees’ intentions to accept IT at their workplace. The study has been conducted in post offices and it is based on both primary and secondary data.
Risk Information Practices in Annual Reports: An Indo-German Collaborative Comparison
Authors: Trivedi Pankaj , Berger Thomas , Parmar Sunil
Published: August 2018

This paper looks at the information given on risks as disclosed in Indian and German annual reports. Such annual reports are a method for overcoming the information asymmetry between investors and managers by gaining information on the performance and the associated risks of listed companies. They can also be of valuable for analysts and managers as a reference for their own reporting and (financial) analysis. We therefore analysed the annual reports of the companies in the Indian SENSEX index and compared them with the companies included in the German DAX index keeping in mind the regulatory framework of their operations. This was done with the help of an evaluation scheme, acting as a guideline for the qualitative content analysis. With disclosure requirements oscillating between mandatory and voluntary, we found that while companies of both indices comply with the mandatory requirements, information on voluntary basis, especially on numerical concrete risk reporting, can be improved, more so in the Indian context. Also, some companies in both economies have shown the way in comprehensively categorizing risk related information which can be adopted, where possible, by other companies in their respective indices. Overall, we found that (1) companies issue only few information on concrete risks, (2) the difference in information quality between the two samples is statistically significant, and (3) size and leverage can explain part of the variance within the samples.

Risk taking is the foundation of business activity. Quantifying it in an accurate manner such that the magnitude, impact, and point in time effect is recognized financially is critical for efficiency in business. Both unhedged and mispriced risk, while opposites in terms of the cost of doing business, have similar effects of loss of capital for the entire community an entity operates with. In this paper, we examine the list of known risks which need to firewalled against for a business to survive as well as thrive. Costing risks and derivatives in a similar manner allows for representing the health of a business in relation to its impact in the reassuringly standardized form of a balance sheet.

The role of translation in the foreign language classroom has been changing, but it still remains a contentious issue. The long-lasting debate whether students of foreign languages might benefit from the use of translation in class might have made practitioners insecure in relation to whether using translation is beneficial or not, what methods are best and when to use translation. The aim of this study is to investigate EFL practitioners’ perspective on translation in teaching foreign languages. Specifically, it explores language for specific purposes (LSP) teachers’ attitudes toward translation at tertiary-level institutions in Croatia. The data were collected by means of an online questionnaire using snowball sampling method in order to reach a greater number of teachers. The respondents were English, German and Italian LSP teachers from a variety of tertiary-level institutions. The study revealed that in the Croatian context the majority of LSP teachers use translation in language teaching, however, there seems to be a lack of certainty about its usefulness. In addition, LSP teachers' approach to translation appears to be rather traditional given there is no diversity in the methods mentioned.

Authors: Yang Na , Gao Li , Zeng Jie
Published: August 2018

As one of the learner factors, most of the reported researches concerning learners’ beliefs mainly deal with the correlation between learners’ beliefs and other learner factors, and mostly belong to cross-sectional study. By contrast, learners’ beliefs are investigated longitudinally in this study---respectively before, after and half a year after a language learning strategy training: TCLTSP model. The influence of the training on learners’ beliefs is analyzed based on the changes of learners’ beliefs.

This research succinctly explicates the areas of problem in Senior Secondary Students’ use of the English Concord in written texts. Language is a social property and has rules that determine how words should be matched to achieve effective communication. Concord in English deals with those rules that govern the co-occurrence of words in sentences. This work is a practical classroom experience and it x–rays the students’ performance in the grammatical, notional and proximity concords respectively. The findings are clearly presented in statistical tables and each of the tables shows the students’ performance in each of the areas. The result shows that the students performed fairly well in notional and proximity concords. The total results, however, led to the conclusion that the students are yet to attain competence in the English concord for good communication.

Learning language through literature has got a great emphasis in foreign language class room since the use of literary text as a resource for teaching macro and micro skills is very popular within the field of language learning. Literary texts increase the learners’ proficiency of integrated language learning as they enable the learners to apply all macro and micro skills. Of the issues to be considered, the contents, their levels of difficulty, their diversity and the appropriateness of the tasks designed based on the contents. This study evaluated the literary texts in preparatory students English text books. Based on the objectives of the study, both qualitative and quantitative research method was employed. The result of the study indicated that the most of the literary texts are above the language competence of the students and the teachers. Teachers strongly affirmed that they have faced to understand the literary texts’ language. The literary texts are not considering the students’ cultural background since almost all of the texts are written by foreign in a foreign context. Moreover, the majority of the literary texts are not related with the unit topic of the book. Using the literary materials in language class, therefore, should take into account the students’ need, motivation, interests, cultural background and language competence.

A Cognitive Construal of English News Headlines: Prominence Dimension
Authors: Xing Xiaoyu , Zhang Li
Published: August 2018

As windows through which people get in touch with the world, English news headlines are extensively studied in both journalistic and linguistic fields. However, little literature has been found to approach their demonstrations and motivations behind. Cognitive Linguistics devotes itself to find out the motivations behind language demonstrations. From the perspective of prominence, one dimension of cognitive construal, this paper discusses the demonstrations and motivations of the news headlines of five different e-papers reporting the same news events. It is concluded that (1) different headlines in different e-papers give prominence to different parts of news events. (2) e-papers’ different attitudes towards the news events cognitively motivate the different demonstrations in terms of prominence.
El efecto testimonial como configuración del pasado colectivo en La ceiba de la memoria, de Roberto Burgos Cantor
Authors: Clavijo Tavera Daniel
Published: August 2018

A partir del diálogo del arte con episodios de violencia y horror en la historia, así como de la configuración de la memoria colectiva, este artículo busca indagar en las implicaciones del discurso testimonial ficcional como mecanismo de construcción de pasado colectivo en La ceiba de la memoria, de Roberto Burgos Cantor. La reflexión incluye tres perspectivas de análisis: la configuración ficcional de un género discursivo propio de la historia, la manera en que dicho procedimiento trasciende ciertos límites de la lógica testimonial y las posibilidades de sentido derivadas de la no-dialogicidad de la expresión del testimonio en la novela.
Apologías humanistas del Imperio y la Conquista. El Antijovio de Ximénez de Quesada y las Elegías de varones ilustres de Indias de Juan de Castellanos
Authors: Restrepo Luis Fernando
Published: August 2018

En la cuarta parte de las Elegías de varones ilustres de Indias, Juan de Castellanos menciona la reiterada insistencia de Gonzalo Ximénez de Quesada en cuanto a que la forma poética más apropiada para cantar las gestas de la conquista de las Indias eran los antiguos versos castellanos, por “ser hijos nacidos de su vientre”, mientras que el Beneficiado de Tunja, por su parte, consideraba válido el uso de la entonces nueva métrica italiana, la ottava rima, pues eran versos engendrados en nuestra lengua, al uso moderno, para renovar la memoria de los conquistadores (Historia del Nuevo Reino de Granada, canto XIII). Si bien parece ser una simple cuestión de formas y lenguaje, no lo es así para el humanismo renacentista.
Egy térszerkezeti modell
Authors: Baráth Etele
Published: August 2018

The conceptual model outlined in the paper was elaborated in order to support regional planning. It is a resource oriented model involving both natural and societal resources . The model aims to facilitate the analysis of inter-relationships among the components of spatial development processes.

ln its first part the paper reviews some of the issues which urge a system oriented approach in the study of the Hungarian settlement network. It assumes that Hungarian urbanists faíled to give answers to basic theoretical questions therefore are unable to provide a reliable background for settlement planning and settlement development. While social scientists manifest an increasing interest in settlement development, urbanists are largely índifferent to social issues. Their scope of interest is stíll restricted to technical problems: the 'reformist wave' in Hungary seems to have passed by the urbanists . The conceptual model outlined in the paper derives regional and settlement development processes from societal needs and pools their operating factors into two subsystems, the so-called sectoral und the so-called spatial systems, which are dialectically related to each other. The second part of the paper gives insight into the contents of spatial analyses made with the application of the model.
Gondolatok a városi turizmus fejlesztéséről, két testvérváros vendégkörének elemzése alapján
Authors: Bakucz Márta
Published: August 2018

A turizmus általános gazdaságélénkítő szerepének lokális érvényesüléséhez elengedhetetlen a keresleti piac igényeinek folyamatos követése, felmérése és elemzése annak érdekében, hogy hatékony tervezésre és cselekvési program összeállítására kerülhessen sor. A 2000 nyarán Pécsett, illetve Grazban végzett turista vendégkör felmérés tapasztalatait összegező tanulmány kísérletet tesz arra, hogy adaptálható osztrák módszerekre és eljárásokra hívja fel az érdekeltek – önkormányzati vezetők, a helyi turisztikai szakemberek, vállalkozók és a lakosság – figyelmét, amelyek az itthoni körülmények között hatékonyan működő városi turizmus kiépítéséhez vezethetnének, ezzel együtt a helyi gazdasági fejlődést is jelentős mértékben előmozdíthatnák. A témának az ad különös aktualitást, hogy – bár a Széchenyi Terv egyik fő fejlesztési célként jelöli meg a turizmust – kifejezetten a városi turizmus fejlesztésére a 2001-2002-re szóló Nemzeti Fejlesztési Terv nem irt ki pályázati lehetőségeket.
Falvaink sorsa az ezredfordulón: a közép-tiszavidéki tapasztalatok

A tanulmány a kevésbé fejlett Közép-Tiszavidék négy községében (Sarud, Tiszakeszi, Tiszaszentimre, Újszentmargita) 1998-ban végzett kérdőíves felmérés tükrében mutatja be a rendszerváltozás után a falusi életkörülményekben (infrastruktúrális ellátottság, lakásviszonyok, lakások felszereltsége, jövedelmi helyzet, vásárlási szokások stb.) bekövetkezett változásokat: hogyan reagáltak azokra a háztartások és az egyének, s milyen stratégiákat alkalmaztak a fennmaradásuk érdekében.
A halogatott regionalizáció mint a területi politika sajátossága az átmenetben
Authors: Rechnitzer János
Published: August 2018

A tanulmány célja bemutatni a magyar regionális politika fontosabb jellemzőit az átmenet időszakában, összehasonlítani azt az Európai Unió regionális politikájának elvárásaival, s mindezek alapján meghatározni azokat a kihívásokat, amelyekkel szembe kell nézni a csatlakozás időszakáig és talán még azután is a hazai területi politikában. Az értékelésnél külön figyelmet szentel a dolgozat a regionalizációnak, a régiók kialakulásának, az azokat segítő és akadályozó tényezőknek.
A határ menti területek jellegzetességeinek átalakulása a 20. század végi Nyugat-Magyarországon
Authors: Hardi Tamás , Nárai Márta
Published: August 2018

Magyarország nyugati határa, az osztrák–magyar államhatár az első világháborút lezáró békerendszerben született meg, hasonlóan Magyarország többi államhatárához. Azonban történeti fejlődésében, jellegzetességeiben lényeges eltéréseket találunk. A két világháború közötti időszakban, mikor a környező, újonnan alakult vagy frissen átalakult nemzetállamok (a kis-antant országok) az új határok elválasztó szerepének fokozására törekedtek nyugati határunk átjárható maradt, Magyarország és Ausztria között a határ nem jelentett akadályt a mindennapi kapcsolatok folytatásában. A szocializmus időszaka alatt azonban ez a határvonal két nagy világrendszer elválasztó gátjává vált, s a szigorúan őrzött határterületek kimaradtak fontos fejlesztési programokból, s a korábban hagyományosan fejlett térségek periférikus helyzetbe kerültek. Az 1989-1990. évi rendszerváltás után a térség helyzete ismételten felértékelődött, s mára az osztrák-magyar határmente jelentős része az ország gazdasági fejlődésének élenjáró területévé vált. Tanulmányunk ennek az utolsó évtizednek a változásait kívánja bemutatni korábbi kutatások eredményeit felhasználva. Szólunk az átalakuló gazdaságról, összehasonlítva azt a szomszédos osztrák területek (Burgenland) fejlődési irányaival; a társadalmi átalakulásról; a határon átnyúló kapcsolatok megváltozásáról és a jövőbéli lehetőségekről.
