Authors: Guarín-Loaiza Gloria Mercedes , Pinilla-Roa Análida Elizabeth
Published: March 2017

Introducción. La hipertensión arterial tiene una prevalencia del 12.3% en Colombia; además, la baja adherencia al tratamiento antihipertensivo y su relación con la calidad de vida aún no se determina.Objetivos. Determinar la adherencia al tratamiento antihipertensivo y establecer su relación con la calidad de vida.Materiales y métodos. Estudio descriptivo observacional de corte transversal en el que se utilizaron instrumentos que incluían variables demográficas: el test de Morisky–Green (adherencia) y el MINICHAL (calidad de vida). Durante la aplicación de los instrumentos se tomó la presión arterial.Resultados. De un total de 242 pacientes (hospitalizados y ambulatorios), 31.4% eran adherentes y 81% tenían hipertensión arterial controlada con una calidad de vida relacionada con la salud dentro de un rango medio de 49.2%. En los pacientes ambulatorios se presentó asociación entre la variable calidad de vida y adherencia (p<0.001).Conclusiones. Es importante valorar la adherencia y la calidad de vida con herramientas específicas, rápidas, económicas y útiles tanto en el ámbito ambulatorio como en el hospitalario; cada vez que se formulan antihipertensivos a un paciente, se debe propender por no comprometer su calidad de vida e intervenir en los aspectos que puedan afectarla.

Introducción. La literatura especializada señala la importancia del terapeuta ocupacional en conflictos violentos al reportar múltiples reflexiones y experiencias; sin embargo, son ausentes los trabajos que en Colombia profundicen en los alcances y posibilidades profesionales según la legislación vigente.Objetivo. Analizar disposiciones del marco legal colombiano relacionadas con conflicto armado para identificar contenidos afines a la terapia ocupacional.Materiales y métodos. Investigación documental acerca de la normatividad colombiana sobre conflicto armado para su respectivo análisis.Resultados. Las disposiciones revisadas no mencionan la terapia ocupacional. Las normas, según áreas de ejercicio, se distribuyen así: bienestar social 21.8%, psicosocial 21.8%, sociolaboral 20.6%, biosocial 20.6% y educación 14%; estas, en su mayoría, cubren a víctimas del conflicto y se interesan en el desplazamiento forzado. Se destacan la mirada diferencial para protección de la población infantil y los procedimientos como atención directa, actividades grupales e intervención con familias.Conclusiones. Se evidencia una necesidad de impulso gremial al reconocimiento social de las posibilidades de la terapia ocupacional en ámbitos distintos al clínico. La falta de claridad por parte de la sociedad y el desconocimiento de legisladores sobre los alcances profesionales de los terapeutas ocupacionales pueden ser causa de la no mención en las disposiciones analizadas. Como retos gremiales queda participar en escenarios de formulación de políticas públicas, divulgar experiencias profesionales en conflictos violentos y fomentar programas dirigidos a actores armados.

Published: March 2017

El objetivo de este estudio fue evaluar la capacidad antioxidante y la calidad post-descongelación de semen equino criopreservado con quercetina y ergotioneina. Nueve eyaculados provenientes de tres caballos criollos colombianos, se criopreservaron bajo los tratamientos: ergotioneina (100 µM), quercetina (100 µM) y control (sin antioxidante). Post-descongelación se evaluaron la capacidad antioxidante total (CAT) del semen, mediante el ensayo del ácido 2,2´-azino-bis-(3-etilbenzotiazolina)-6-sulfonico (ABTS●+); la movilidad total (MT), la movilidad progresiva (MP), la hiperactividad (HA) y las velocidades curvilínea (VCL), lineal (VSL) y media (VAP), mediante el sistema computarizado SCA®; la integridad estructural de la membrana y la integridad acrosómica, por microscopia de fluorescencia mediante las sondas SYBR/IP y FITC/PNA, respectivamente; la morfología mediante la tinción eosina-nigrosina y la integridad funcional de membrana por la prueba hipoosmotica (HOS). Se realizó el ajuste de modelos lineales generalizados (GLM) y la comparación de medias por Tukey. La CAT (µmol trolox / ml) del semen descongelado fue superior para la ergotioneina (4.0 ± 0.3) y la quercetina (3.9 ± 0.4), respecto al control (2.6 ± 1.5). Para la MT se encontró una media superior para la ergotioneina (70.3 ± 11.2 %), respecto a la quercetina (63 ± 10.5 %) y al control (66.1 ± 11.2 %) (p < 0.05). Para MP, HA, VCL, VSL y VAP, el tratamiento control presentó valores superiores a los tratamientos con antioxidantes (p < 0.05). Se concluye que la ergotioneina y la quercetina incrementan la CAT e influyen sobre la movilidad y la cinética post-descongelación del semen equino.

Authors: Büyüktuncel Ebru , Porgalı Esra , Özkara Serpil
Published: March 2017

A new molecularly imprinted polymer (MIP) was prepared by using catechin (C) as the template molecule. The polymer was characterized by swelling tests, scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), and Fourier transform infrared (FTIR) spectroscopy. The MIP with high recovery was selected as a solid-phase extraction (SPE) sorbent in this work. The standard solutions were directly applied onto the SPE cartridges following loading, washing, and elution procedures. A solution of the collected fractions was analyzed by high-performance liquid chromatography–diode-array detection (DAD) and fluorescence detector. The optimization of the method and validation was achieved on a C18 column (5 μm, 250 × 4.6 mm) with methanol–water (35:65, v/v) mixture adjusted pH 2.5 as the mobile phase at a flow rate of 1 mL min−1 at room temperature. The selectivity coefficient (k) of imprinted p(HEMA–MAH) cryogel was 5.1-fold that of non-imprinted cryogel. It showed good selectivity and affinity for C molecule. A comparison was made between the results obtained with the MIP cartridges and a traditional C18 reversed-phase cartridge. It was observed that 2.3 times higher recovery of C can be obtained on catechin-MIP cryogel. The results of the presented work showed that the prepared MIP can be used as SPE sorbent for extracting of C from red wines.

Analiza roli kredytów konsumpcyjnych w procesie dyfuzji innowacji – ujęcie aksjomatyczne
Authors: Ciałowicz Beata
Published: March 2017

The paper’s aim is to formally analyse the role consumer loans play in the process of diffusing innovation. To that end, the following tools are employed: a set-theoretical and topological apparatus borrowed from general equilibrium theory and a static model of the Debreu economy with money in the form of a multi-range relational system. Specific extensions are defined for this model with respect to innovative changes in a consumption sphere or imitative changes in the production sphere. A formal definition of the diffusion of innovation is then introduced and analysis of the role of consumer loans in this process is presented. Finally, it is shown that consumer loans may improve the process’ ultimate equilibrium.
Analiza ścieżek rozwoju gospodarczego polskich regionów
Authors: Batóg Jacek , Dmytrów Krzysztof
Published: March 2017

The research consists of two stages. The first provides a comparative analysis of the level of economic development of Polish voivodships for the period 2000–2013. The second evaluates how similar the paths of economic development of individual regions are. To achieve the latter end, measures of the similarity of time series were applied, particularly dynamic time warping. The starting point for this method is to compute a matrix of costs containing the distances between all the elements of the time series to be analysed (pairwise). The optimum path between the starting and the final points may then be found. This path is characterised by the minimum value of the cumulated distances. The results evidence strong similarities in dynamics and high differences in the level of economic development of Polish voivodships and can be useful for the programming of regional policy, especially for determining whether the foundations for common programmes of the cohesion policy for given groups of regions exist.

Published: March 2017

When evaluating a property, an appraiser should find a real estate market that is similar to the market the evaluated property is on. While similar markets will sometimes not be found in the same city, demographic and economic ratios can be used as criterion of similarity. The analysis and comparison of the structures of apartments sold on two housing markets could also help in confirming the similarity of markets. The similarity of markets could be used in further analyses and property evaluations.The aim of the research is to compare the structures of apartments sold in cities according to the apartments’ attributes, including date of transaction, price, area and location in the city. The housing markets in Szczecin and Bydgoszcz are compared. These cities have a similar number of transactions on their housing markets and have populations of similar size. The data come from notarial deeds for transactions on the secondary housing markets in Szczecin and Bydgoszcz. The analysis is done for two years: 2009, the first year of crisis on the real estate market, and 2015, the year with the most recent data. Measures of entropy and the similarities of the structures are applied.

Authors: Strożek Piotr , Jewczak Maciej
Published: March 2017

With the evolution of information and communication systems it is possible to speed up the flow of information. These processes have occurred and continue to occur in different areas of social and economic life, and concern both households and the enterprises. Consequently the possibility of building a knowledge-based economy has arisen. Additionally, the demand for ever more advanced digital technology is constantly increasing, which lays the foundation for the information society to function.The aim of the paper is a multi-dimensional approach to analysing the development of modern telecommunication infrastructure in Poland. The research issues are presented in regional terms, since digital networks have started expanding at this level. It was assumed that there were significant disproportions in interregional development of the ICT sector in Poland. That assumption was verified using appropriate taxonomic methods, including synthetic measure of development in standarised terms and cluster analysis. On the basis of the designated ICT indices, regions were classified and homogenously grouped according to the state and performance of the ICT sector. The analyses were carried out in the period 2003–2014.

Published: March 2017

As a result of rapidly increased smart-phone application development, it is critical to identify the influential factors of the information search process of users. In addition, the communication activities in the circumstance of smart-phone application need to be identified. Therefore, the purpose of this paper is to investigate the relationships among the information involvement, information value, information search behavior, and the types of e-communication through a smart-phone application in relation to tourism information. A total of 1,040 data were collected from an on-site survey and 480 were analyzed using an SPSS program. The results indicate that the smart phone application user information search activities and types of e-communication should be significantly related to information involvement, perceived information value (hedonic, risk avoidance, utilitarian), and the use of language. This must be done while simultaneously controlling for demographic characteristics. Based on the results of this research, theoretical and practical implications of these findings are discussed.
The Effects of Role Ambiguity and Role Conflict in Medical Tourism Coordinator Work on Job Satisfaction and Job Performance
Authors:   The Tourism Sciences Society Of Korea, Cho Seung-A
Published: March 2017

This research identified the effects of role ambiguity and role conflict in medical tourism coordinator work on job satisfaction and job performance. Three hypotheses were formulated based on theoretical discussion and data collected from attendances at a job- training center for medical tourism coordinators. The results are summarized as follows. First, there were differences in the perception of role ambiguity, role conflict, job satisfaction and job performance between the group performing as medical tourism coordinators and doing other work and the group performing only medical tourism coordinator. Second, as the level of role ambiguity and role conflict increases, it has a negative influence on the 'aptitude and future possibilities' factor as it applies to job satisfaction factors. Third, as the level of 'aptitude and future possibilities' and 'organization support' factors grow higher, it has a positive influence on job performance. Findings from this study show that the role ambiguity and role conflict in medical tourism coordinator work managed to invigorate medical tourism. Therefore, the government, hospitals and medical tourism agencies need to suggest a system of role regulation. Specifically, an examination to adopt an employment quota system in hospitals and medical tourism agencies over a certain size needs to be established. They should also provide job descriptions and a system of promotion and education. Finally, they need a report line that ends at a superior.
An Analysis of Social Interaction between Disabled People and Volunteers Based on Tourism
Authors:   The Tourism Sciences Society Of Korea, Kim Ji Sun , Lee Hoon
Published: March 2017

Disabled people normally participate in tourist activities with volunteers, and it is meaningful in that the tourism offers a chance for disabled and non-disabled people to interact with one another. This study seeks to identify the meaning of the tourist experience exhibited during an accompanied tour taken by disabled and non-disabled people. Then the study analyzes it in terms of the social interaction exhibited. Data were collected from in-depth interviews conducted with four disabled people and six volunteer workers using six participant-observations. The analysis of data was done using Colaizzi's method of phenomenological study and Goffman’s social interaction system. The results show that disabled individuals and the volunteers communicated through conversation, touch, facial-expression, and observation. Such non-verbal communication was important for the disabled. Volunteers that had experienced difficulties in care, were in conflict with others. Also, disabled people and volunteers were seen to expand their relationships as they related to welfare workers, other volunteers, parents of disabled people, and other disabled people. Hence, disabled people and volunteers experienced social interaction during their accompanied tour, which led to a change in their inter-relationships and tourism behavior. This research is meaningful in that it approached the topic from the integrated viewpoint of two subjects, disabled people and volunteers, within a tourism context. It also emphasized the role of tourism in leading social integration and suggested ways to induce positive interaction.
Agricultural Tourism Research based on Exchange Theory and Community Attachment: Focused on a Farming-fishing Village in Jeju Island
Authors:   The Tourism Sciences Society Of Korea, Kim Min-Ji , Nam Jae-Cheul , Lee Seung-Woo
Published: March 2017

The purpose of this study is to focus on agricultural tourism from the perspective of social exchange theory. Amongst the many stakeholders, residents are the group that is affected most directly and indirectly by tourism development. Therefore, understanding how their perceptions are construed is a crucial topic. Although interest in agritourism has increased, the scale of rural community has decreased gradually so research in this area is still lacking. The study data included a research population from a small-scale farming and fishing village located on Jeju Island. Using Spearman’s Rank Order correlation analysis, it is clear that benefits of tourism development have a positive relationship with tourism development. Economic and environmental impacts are significant, but not statistically significant to cause sociocultural impacts. The hypothesis that examining the cost of tourism development would be negatively related to tourism development was rejected. The third hypothesis that purports the positive relationship between community attachment and tourism development was statistically significant. Finally, the relationship between community attachment and the impact of tourism development showed a significantly positive effect and no significant negative impact.
El universo discursivo político del tema de la movilidad, Quito 2010-2014
Authors: Arenivar Madeleine
Published: March 2017

A nivel internacional existe una tendencia creciente de imponer un nuevo modelo de movilidad, basado en las ideas del público complejo, la meta de mayor acceso y la sostenibilidad en vez de las ideas del viejo modelo del público de individuos, la meta de rapidez, y la expansión del consumo. El intento de cambiar el paradigma de la movilidad implica una lucha para la opinión pública y los términos del debate por los actores políticos. Este artículo busca entender, a través de los conceptos de la teoría del institucionalismo discursivo, cómo el discurso comunicativo del municipio de Quito del período 2010-2014 demuestra un avance hacía la incorporación gradual de las ideas del nuevo modelo de la movilidad dentro del discurso oficial.

Authors: Pinzón López Natalia
Published: March 2017

Este artículo tiene como objetivo proponer herramientas prácticas y teóricas para la comprensión de acciones colectivas cuya finalidad sea una transición agroecológica. El marco teórico se fundamenta en las principales teorías de acción colectiva y movilización social en el contexto del mundo occidental. La propuesta se materializa en lineamientos que fungen como respuesta a las siguientes preguntas: ¿qué sociedad busca la acción colectiva y qué significa la agroecología?, ¿qué motivaciones existen para participar en la transición agroecológica y en la acción colectiva que la promueve?, ¿cuáles son las estrategias para alcanzar la transición agroecológica? y ¿cuál es el contexto político y cómo incide en la acción colectiva y en la transición agroecológica del territorio? Las respuestas a estas preguntas permiten analizar la disposición de los actores para cambiar las prácticas productivas tradicionales por agroecológicas, y asimismo, para examinar la capacidad de cambio y transformación social que tiene la acción colectiva en el territorio.

Published: March 2017

Las primeras historias sobre el origen de las revoluciones y emancipaciones hispanoamericanas fueron gestadas y publicadas antes de que las guerras de independencia hubieran terminado. Algunas de estas obras lo fueron en Estados Unidos. Por otro lado, historias de la revolución editadas en América española fueron reseñadas en revistas literarias estadounidenses de amplia difusión. En este artículo se estudiará entonces el papel que cumplieron los estadounidenses en la fabricación y la difusión de esta naciente historiografía hispanoamericana. El propósito es destacar el protagonismo de Estados Unidos en el doble proceso del nacimiento de estos estados modernos y de sus historiografías.

Feminization of poverty: the Nigerian account
Authors: Nwaoduh E.
Published: March 2017

The paper is an attempt at contributing to the on-going debate on feminization of poverty by discussing the concept of feminization poverty in Nigeria. Women in Nigeria cannot be seen as a minority group and anything (as poverty is the case here) that is a challenges to them as a group should not be neglected as it has and will continue to have tremendous negative effects on the development of the country. Prior to this time, many poverty alleviation programs which are highlighted in the work have been initiated by several governments and they achieved some successes although to a larger extent due to poor implementation and corruption they failed as is evident in the level of poverty in Nigeria. The research elucidates the causes, effects and consequences of women's poverty in Nigeria. Some of the causes discussed include limited access to resources that help women escape from poverty; low income and work discrimination; lack of access to good health care services and socio-cultural exclusions. While some of the effects include poor health and health care access; inadequate food and poor nutrition; lack or poor quality of education; limited access to information and technological development. Several remedies such as increasing the productive capacity of women through access to Economic resources, information and technical assistance, which will increase their income and improve nutrition, education, health care and status within the household were also brought into perspective. Recommendations were made to all concerned groups - the women, men and government agencies and apparatuses, one of which includes: the availability of skill acquisition programs, which should be free and accessible for women especially those in the rural area should be organised, by the government, non-governmental agencies, and well-meaning philanthropists. It was concluded that the structure of the Nigeria society gives room for female poverty.
Laser-assisted bioprinting at different wavelengths and pulse durations with a metal dynamic release layer: A parametric study
Authors: Koch Lothar , Brandt Ole , Deiwick Andrea , Chichkov Boris
Published: March 2017

For more than a decade, living cells and biomaterials (typically hydrogels) are printed via laser-assisted bioprinting. Often, a thin metal layer is applied as laser-absorbing material called dynamic release layer (DRL). This layer is vaporized by focused laser pulses generating vapor pressure that propels forward a coated biomaterial. Different lasers with laser wavelengths from 193 to 1064 nanometer have been used. As a metal DRL gold, silver, or titanium layers have been used. The applied laser pulse durations were usually in the nanosecond range from 1 to 30 ns. In addition, some studies with femtosecond lasers have been published. However, there are no studies on the effect of all these lasers parameters on bioprinting with a metal DRL, and on comparing different wavelengths and pulse durations – except one study comparing 500 femtosecond pulses with 15 ns pulses. In this paper, the effects of laser wavelength (355, 532, and 1064 nm) and laser pulse duration (in the range of 8 to 200 ns) are investigated. Furthermore, the effects of laser pulse energy, intensity, and focal spot size are studied. The printed droplet volume, hydrogel jet velocity, and cell viability are analyzed.

Now it is being applied to 3D cell printing, which can position cells and biomaterials, such as growth factors, at desired positions in the 3D space. However, there are some challenges of 3D cell printing, such as cell damage during the printing process and the inability to produce a porous 3D shape owing to the embedding of cells in the hydrogel-based printing ink, which should be biocompatible, biodegradable, and non-toxic, etc. Therefore, researchers have been studying ways to balance or enhance the post-print cell viability and the print-ability of 3D cell printing technologies by accommodating several mechanical, electrical, and chemical based systems. In this mini-review, several common 3D cell printing methods and their modified applications are introduced for overcoming deficiencies of the cell printing process.

Tissue engineering approaches have been adopted to address challenges in osteochondral tissue regeneration. Single phase scaffolds, which consist of only one single material throughout the whole structure, have been used extensively in these tissue engineering approaches. However, a single phase scaffold is insufficient in providing all the properties required for regeneration and repair of osteochondral defects. Biphasic scaffolds with two distinct phases of titanium/type 1 c ollagen and titanium-tantalum/type 1 collagen were developed for the first time using selective laser melting and collagen infiltration. Observation of the biphasic scaffolds demonstrated continuous interface between the two phases and mechanical characterization of the metallic scaffolds support the feasibility of the newly developed scaffolds for tissue engineering in osteochondral defects.
In vitro pre-vascularization strategies for tissue engineered constructs–Bioprinting and others
Authors: Liew Andy Wen Loong , Zhang Yilei
Published: March 2017

Tissue-engineered products commercially available today have been limited to thin avascular tissue such as skin and cartilage. The fabrication of thicker, more complex tissue still eludes scientists today. One reason for this is the lack of effective techniques to incorporate functional vascular networks within thick tissue constructs. Vascular networks provide cells throughout the tissue with adequate oxygen and nutrients; cells located within thick un-vascularized tissue implants eventually die due to oxygen and nutrient deficiency. Vascularization has been identified as one of the key components in the field of tissue engineering. In order to fabricate biomimetic tissue which accurately recapitulates our native tissue environment, in vitro pre-vascularization strategies need to be developed. In this review, we describe various in vitro vascularization techniques developed recently which employ different technologies such as bioprinting, microfluidics, micropatterning, wire molding, and cell sheet engineering. We describe the fabrication process and unique characteristics of each technique, as well as provide our perspective on the future of the field.

One of the important constituents in tissue engineering is scaffold, which provides structural support and suitable microenvironment for the cell attachment, growth and proliferation. To fabricate micro/nano structures for soft tissue repair and three-dimensional (3D) cell culture, the key is to improve fibre-based scaffold fabrication. Electrohydrodynamic (EHD) jetting is capable of producing and orientating submicron fibres for 3D scaffold fabrication. In this work, an EHD-jetting system was developed to explore the relationship between vital processing parameters and fibre characteristics. In this study, polycaprolactone (PCL) solution prepared by dissolving PCL pellets in acetic acid was used to fabricate the scaffolds. The influence of voltage, motorized stage speed, solution feed rate, and solution concentration on fibre characteristics and scaffold pattern were studied. Morphology of the EHD-jetted PCL fibres and scaffolds were analysed using optical microscope images and scanning electron microscope (SEM) images. Multi-layer scaffolds with the varied coiled pattern were fabricated and analysed. Cell attachment and proliferation have to be investigated in the future by further cell culture studies on these multi-layer coiled scaffolds.

An essential element of Internet literacy for college students is the ability to locate, select,
evaluate, synthesize, and cite sources in their study. This study began with the assumption that
there are stumpy Internet competency and a big digital divide among the students in the engineering
colleges in Solan District of Himachal Pradesh, (India). A survey was conducted to know the
student practices on Internet. A questionnaire was designed and distributed to 480 students.
After filling up, a total of 424 questionnaires with a response rate of 87.2% were received. The
objective of this study was to identify the preferred criteria of using the Internet in the engineering
colleges. This paper examines the digital competencies of the students and discusses on different
aspects of Internet usage. However, the study limits only a few colleges, yet it represents an
overview of the real condition and impact in broader prospects.

Authors: Parihar Bharti Choudhary , Goyal Abhilasha
Published: March 2017

Background: Foetal death or stillbirth is a major obstetrical complication and a devastating experience for the pregnant patients and relatives. Worldwide an estimate of at least 3.2 million stillbirths occurs each year. There are intensified demands on medical, political and epidemiological ground for proper determination and classification of causes of perinatal death. The aim of this study was to test a new classification system- Re. Co. De. Classification (Relevant Condition at Death) for stillbirths to improve our understanding of the main causes and conditions associated with foetal deaths.Methods: This study was a hospital based Prospective study conducted in department of obstetrics and Gynaecology, SZH, Bhopal. The study included 463 women who were admitted with Intra Uterine Foetal Demise. All cases were evaluated and after delivery the stillborn baby, the placenta and cord were examined. The causes were classified according to Re. Co. De. System.Results: The analysis of the new classification system Re. Co. De. Allowed attributable causes to about 90.72% of causes of still births explained where 9.28% were unexplained. The commonest cause was found to be class F4-Toxaemia of pregnancy (13.17%) followed by class A7- IUGR (10.58%), class C1-Abruptio placentae (10.36%), class E3-Obstructed labour (9.8%) and class A1- Lethal congenital malformations (8.42%).Conclusions: The Re. Co. De. Classification system gives us a better understanding of antecedents of stillbirths and the clinical practices, which need to be addressed to reduce perinatal mortality and have a better obstetric result in the next pregnancy.

The Yanomami sociopolitical dynamics in the context of the Hutukara creation: the Pata Thëpë and the emergency of young political leaderships
Authors: Carvalho Maria Auxiliadora Lima de
Published: March 2017

The current study is an effort to understand the Yanomami sociopolitical dynamic in the context of mobilization and articulation that preceded the establishment of Hutukara Yanomami Association; in that context, new patterns of dialogs and knowledge were established, fact that has delineated new forms of relationship between youth and elder leaders. From reads in ethnology, history and I my own ethnography work, I try to understand the place of the new organization in the sociopolitical dynamic of Yanomami and its implication for the local groups and also in the relationship between traditional and youth leaders. I try to show that speech and knowledge are the two major principles that connect the youth and traditional leaders; the choice of youth leaders as major political speaker does not mean the elder’s loss of power; the Yanomami see the presence of the youth in the meetings as necessary, due to the necessity of decoding their relationship with non-Indians.
Society, environment and frontier in the Amazon: some historical and political topics
Authors: Santos Nelvio Paulo Dutra
Published: March 2017

This work is the result of thematic discussions on topics covered during the First International Seminar on Society and Frontiers, sponsored by PPGSOF/UFRR, on December 2012 in Boa Vista. Here we try to establish some relationships between the categories society, environment and frontier in the Amazon, especially from the perspective of political and administrative developments, from colonial times to recent times. The Amazon frontier is characterized here as nothing more than a historical supplier of natural resources as well as more than a space delimited by the National State. Its traditional inhabitants are seen as builders of their own space, and are also incorporated into projects of the National State in order to meet existing demands elsewhere, either at the beginning of the conquest or at present. In short, it is how the economics and politics overcome peoples and environment and shaped life in the area known today as the Brazilian Amazon.

LA FIESTA DE LA VIRGEN DEL CARMEN DE LA TIRANA. ¿RITUAL O ESPECTACULO?
Authors: Muñoz Luis Campos
Published: March 2017

En este artículo abordo la fiesta de la Virgen del Carmen de La Tirana del Tamarugal en Tarapacá, Chile, a partir de una comparación entre sus aspectos rituales religiosos y sus elementos de escenificación teatral, de espectáculo y de entretenimiento. Siguiendo a R. Schechner (2000) la idea es caracterizar la ceremonia entendiéndola como una mezcla de ambos polos, el de la ritualidad y el del entretenimiento superando tal contradicción a partir de un análisis basado en los estudios de la performance, en la línea del mismo Schechner (2000), Taylor (2012) y Fischer-Lichte (2011).

IMIGRAÇÃO DE JOVENS MULHERES BRASILEIRAS NA GUIANA FRANCESA: ENTRE CATEGORIZAÇÕES ETNONACIONAIS E ESTRATÉGIAS DE INTEGRAÇÃO NOS “ESPAÇOS DE INTEGRABILIDADE” DA SOCIEDADE DE RECEPÇÃO
Authors: Silva Brigida Ticiane Ferreira da
Published: March 2017

A presente pesquisa investiga a trajetória de oito brasileiras instaladas na Guiana Francesa, em situação de miscigenação conjugal - cônjuges de nacionalidade estrangeira - e inseridas no mercado de trabalho, com o propósito de identificar a maneira como elas se percebem no meio profissional e social, mas também a maneira como estas brasileiras são percebidas pelos nativos. Nesta pesquisa, o conceito de « representação » está interligado a uma série de outros conceitos tais que sentimento de pertencer, identidade e estratégias empregadas pelas residentes brasileiras para se inserirem socialmente na sociedade guianense. Como método de estudo escolhemos as abordagens autobiográficas, mais precisamente relatos de experiência porque permitem um certo distanciamento de nossas interlocutoras em relação às experiências vividas e as ajudam a capitalizar e a conceituar as estratégias de inserção social por elas utilizadas.
