Quantitative Reduction of Vowels Following Soft Consonants in the Russian Speech of Lithuanians
Authors: Balšaitytė Danutė
Published: December 2019

This investigation of the acoustic characteristics of phonetic units in the Russian speech of Lithuanians is important for a description of the mechanisms of speech production in a situation of the interference of two languages (native and studied), and for the solution of applied problems of teaching (or correcting) Russian phonetics to Lithuanians.The article analyses the average duration (in milliseconds) of the Russian stressed vowels [i], [e], [a], [u], and their unstressed allophones, when they follow soft consonants in the speech of Lithuanians. The results of the spectral analysis show peculiarities of quantitative reduction of Russian vowels in the speech of Lithuanians, due to the interference of the phonetic systems of the two languages.Four major types of distinctions – in the phonological and phonetic systems of the genetically related Russian and Lithuanian languages, in the degree of quantitative reduction of vowels, in the relation between the duration of different types of unstressed vowels in different positions, and in the relation between the duration of unstressed vowels depending on the placement of the stress – allow deviations from Russian norms of pronunciation to be predicted in the Russian speech of Lithuanians.In unstressed syllables, Lithuanians pronounce vowels of varying duration in place of the graphemes и, е and я, which testifies to the unequal degree of quantitative reduction of these vowels. In Russian, these vowels in unstressed positions are expressed by the same sound and cease to differ. In the pronunciation of Lithuanians, the weak quantitative reduction of the Russian vowel [a] (grapheme я) and the insignificant shortening of the duration of [u] can be observed in all unstressed syllables.According to the received data, in the Russian speech of Lithuanians, a poststressed, non-final vowel can be longer than a vowel in the second prestressed syllable; this breaks the opposition of duration of poststressed vowels to that of all pre-stressed vowels which is characteristic of Russian.

Costa Rica: Estimaciones de la tasa de desempleo que no acelera la inflación
Authors: Álvarez Corrales Cristian , Muñoz-Salas Evelyn
Published: December 2019

Este documento presenta varias estimaciones de la tasa de desempleo que no acelera la inflación (NAIRU por sus siglas en inglés) para Costa Rica. De los resultados obtenidos, destaca lo siguiente: este indicador muestra una tendencia creciente desde inicios de los noventa, que se acentúa posterior a la Gran Recesión, periodo a partir del cual Costa Rica exhibe tasas de inflación históricamente bajas; las estimaciones de brecha de desempleo (diferencia entre la tasa de desempleo observada y la NAIRU) apuntan a que desde inicios de los noventa y hasta los primeros años de la década de los 2000, esta tiende a ser mayormente negativa, y positiva en adelante. Para el segundo trimestre de 2017, las diferentes estimaciones coinciden en señalar que la brecha de desempleo estaba cerrada, indicando la ausencia de presiones de demanda agregada. Asimismo, a partir del año 2004 se encuentra un fortalecimiento en la relación entre brecha de desempleo e inflación.

Authors: Quesada Chacón Aldo Jesús , Nakajima Shiori , Rojas Camacho Pedro A. , Rojas Alvarado Carlos
Published: December 2019

El seguimiento de las características del bosque es relevante en el contexto de cambio climático. En este estudio, se ha evaluado la estructura vertical y horizontal, así como las reservas de carbono de un parche boscoso de 28 ha en sucesión temprana en el Caribe de Costa Rica. Esta evaluación se ha hecho con base en el uso de la tierra y en una hipótesis de homogeneidad forestal. Los resultados indicaron que el promedio del DAP, la altura de los árboles y la apertura del dosel fueron 1.15 m, 20.83 m y 18.5%, respectivamente. De las seis variables estudiadas, el DAP y la apertura de dosel fueron las más importantes para determinar la estructura forestal y los resultados mostraron alta homogeneidad en el bosque. Un cálculo de la biomasa sobre el suelo determinó que la finca estudiada tiene entre 100-130 T por hectárea para un total de 1372-1795 T de carbono total sobre el bosque. Este estudio representó el primer acercamiento a la investigación forestal de la estación experimental bajo análisis y ha sido importante para determinar la línea base de información de esta. Se espera que futuros estudios puedan utilizar la información de la presente investigación para darle seguimiento a la progresión boscosa en ese sitio.
Assessing the invasion speed of triatomine populations, chagas disease vectors evaluación de la velocidad de invasión de poblaciones de vectores triatominos de la enfermedad de chagas
Authors: Mahdjoub Tewfik , Kribs Christopher M.
Published: December 2019

Spraying insecticides to control triatomine populations, the vectors of Chagas disease, does not prevent the disease’s reemergence in infested areas. Mathematical models try to explain this reemergence in terms of the factors underlying sylvatic transmission of the parasite Trypanosoma cruzi. The presence of reservoir hosts such as woodrats is essential to the infection’s geographical spread. This study models a vector-host system using integrodifference equations to incorporate dispersal as well as hostvector interactions. These equations capture, simultaneously, the three processes taking place between successive generations: demography, infection and spatial dispersal. Travelling waves, the solutions of the integrodifference equations thus derived, allow one to calculate numerically the invasion speed of the disease. Neubert-Caswell’s theorem can then be applied to calculate the analytical invasion speed.
Modeling post-kala-azar dermal leishmaniasis as an infection reservoir for visceral leishmaniasis
Authors: Calderón Andrea , Landrith Ryan , Le Nhan , Muñoz Ileana , Kribs Christopher M.
Published: December 2019

Visceral Leishmaniasis (VL) is a potentially fatal disease caused by the protozoan parasite Leishmania donovani. This disease is a health problem for the very poor because it results in thousands of deaths and illnesses every year. Some countries, such as India and Bangladesh, have started programs to reduce the occurrences of VL by focusing on early diagnosis and complete treatment of VL. Post-Kala-azar Dermal Leishmaniasis (PKDL) is a cutaneous manifestation of Leishmaniasis that can occur following the incomplete treatment of VL. Diagnosis and treatment of PKDL are limited in affected regions, and PKDL has been identified as a possible reservoir for infection. This study develops a mathematical model of the relationship between the level of PKDL treatment and the incidences of VL during a given period. The results indicate a nearly linear relationship between PKDL treatment rates and the percent reduction of VL incidences. With the current treatments available and considering achievable levels of treatment, the model predicts that up to 20% of VL cases could be prevented by treating new PKDL cases. Hypothetical combined treatment initiatives including bed nets and insecticide spraying are also considered. Results suggest that the population of individuals with PKDL is certainly a significant factor in the transmission of L. donovani infection, with treatment of new cases particularly important.
Uso y abuso de los animales: responsabilidades éticas de la Psicología
Authors: González Suárez Mirta
Published: December 2019

Desde sus inicios la Psicología ha tenido relación con especies no humanas, utilizándolas de diversas maneras. En los clásicos estudios de Pavlov y Skinner se evidencia la crueldad reiterada, e incluso investigaciones más recientes revelan también el uso impune de procedimientos dolorosos. Cabe señalar que desde el siglo pasado existen indicios sobre la tortura a animales en personas menores de edad y posterior conducta violenta hacia humanos, de manera que ésta se asocia a trastornos en el ICD-10  y DSM-5.

Al analizar la relación con los animales destaca también su utilización en procesos terapéuticos, sobre todo con la participación de perros, gatos y equinos, los cuales aportan beneficios a la salud mental. Sin embargo, de manera generalizada se observa una tendencia humano-céntrica, si bien, cabe destacar, existen avances éticos que indican que los seres sintientes tienen derechos, y deben ser respetados.

El artículo presenta un resumen desde la psicología sobre la relación inter-especies, concluyendo que es necesaria una aproximación en el marco de los derechos de los animales. Es urgente el desarrollo de la investigación-acción que promueva la empatía con los animales y motive la educación por una cultura de paz y respeto a los seres sintientes y al entorno en general.

This study aims to understand Islamic management works in business organizations. We intend to expand this area of study while affirming the main argument by raising studies in culinary organizations. Waroeng Group was appointed as a case. It was considered successful in internalizing Islam into the organization's work system. Reviewing the workings of the WG along with the criteria within it are the main focus. We follow the pattern of qualitative work, such as make observations and interviews early, perform data collection, and write the results of the field to the worksheet.The study found that initial emphasis should emerge from a leader (top Management). We call it by ‘the call of the heart’, not because of the encouragement of the other party or are profitable. So understanding that leadership is a reorientation intention readable work, building work paradigm for worship (to Allah), ukhuwah Islamiyah, and worship as the income base of the organization. Then bringing up a special team that is able to present the Islamic management program. WG restructures the organization chart by providing a special position for the department of the spiritual company (DSC).The DSC is led by a person who is able to integrate and interconnection of Islam and business, call it Ustadz. Organizing the needs of employees into a DSC workload. Coaching begins with recruitment and selection, then providing sufficient time for training. WG train new employees about 40 days prior to the employment contract. Furthermore, the paradigm of working for worship has spawned a new paradigm, working for da'wah.That is a special finding in this study. The working not to save oneself, but also to insiders and outside organizations. WG provides da’wah program from internal to internal, internal to external, external to external. This study provides the way of Islamic management work, so it is considered able to answer the needs of practitioners and academics, especially Islamic management consultants to bring the Islamic culture, especially in the context of business organizations.

The study aims to examine the influence of intellectual capital to social performance of Islamic banks. The study assumes there is an intervening role of financial performance on the relation between intellectual capital and social performance of Islamic banks. The VAIC (valued added intellectual capital) is used to measure the intellectual capital. While social capital of Islamic banks comprises four main aspects which are contribution economic development, society, stakeholders, and human development & research. The financial performance is represented by ROA and ROE. The study finds that intellectual capital of Islamic banks has an increasing performance during the period of the study where human capital is the main backbone. Otherwise, social performances of Islamic banks are relatively fluctuated and tend to remain stable during the period. The statistical test shows that intellectual capital has no significant impact on social performance of Islamic banks. However intellectual capital positively and significantly influences financial performance of Islamic banks.

Two-Stage Anaerobic Co-digestion of Landfill Leachate and Starch Wastes Using Anaerobic Biofilm Reactor for Methane Production
Authors: Darwin  , Triovanta Ulfa , Rinaldi Ridho
Published: December 2019

The study aims to evaluate two-stage anaerobic co-digestion of leachate and starch waste using anaerobic biofilm bioreactor to enhance methane production. The anaerobic digestion process was operated under the mesophilic condition at 35 ± 1 °C. Hydraulic retention time (HRT) applied to the acidogenesis and methanogenesis reactors were 5 and 25 days, respectively. The organic loading rate (OLR) used in the process of acidogenesis was 2.91 gram volatile solid /L.day, while methanogenesis was 0.58 gram volatile solid (VS) per liter per day. Results showed that two-stage process using biofilm was an effective method for operating anaerobic co-digestion of starch waste and landfill leachate in which the system produced higher methane yield at 125.11 mL methane (CH4) per gram volatile solid (VS) added (mL.CH4/g.VS.added) in comparison to the single-stage process (20.57 mL CH4/g.VS.added) and two-stage process (77.60 mL CH4/g.VS.added) without using biofilm. Two-stage process using biofilm also effectively reduced organic matters in the culture in which the system reached 61% BOD removal in comparison to the single-stage process and two-stage process without biofilm that only had 27.6 and 39.3% BOD removal, respectively. This study suggested that the two-stage process using biofilm would be the preferred technique for treating starch waste and landfill leachate.
Considerations of Regional Coherences for the Development of Renewable Energy Technologies Used in South Part of Transdanubian Region of Hungary
Authors: Illes Zoltan , Szendro Peter , Unk Janosne
Published: December 2019

The existing effective domestic regional development framework requires analyses for increasingly wider areas (micro, meso and even macro regions) before operational – short-term – local developments to be prepared and implemented.

Such comprehensive complex studies or larger-term programmes may demonstrate the profitability of the given project and can complement it with combined utilization technologies; in the case of Himesháza several locally known renewable energy sources could facilitate geothermal heat, later electricity supply, e.g. local biomass (biogas-based) recovery technology (organic waste of the local pig farm) and, for example, the construction of a low-power “dwarf” hydroelectric power plant chain based on rich watercourses of the region (the “southern dwarves” in Hungary) and the connection of existing solar utility facilities to a modern “smart grid” system in the longer term.

Himesháza, located in southern Hungary in Baranya county, is developing; it has a detailed feasibility study of a thermal energy supply network and an energy supply development plan.

Based on the geothermal characteristics of Baranya county it would be reasonable to encourage the development of smaller-scale, decentralized heating systems for dynamic settlements. Several settlements in close proximity to Himesháza have already explored thermal wells. Power generation with a small scale, closed-loop system can be used in the project region for thermal water with an outflow temperature of 90 °C. The heating system may also be able to fulfill the needs of recreational, vacation-based or complex thermal spa facilities formerly planned in the region. Moreover, the system could also be capable of utilizing a larger spectrum of renewable energy through its combination with photovoltaic technology.

Due to the country's favorable agricultural characteristics, Hungary's biomass potential is higher than the European average. The utilization of organic waste from agricultural and farming sectors is highly recommended in Baranya county; biogas production seems to be the most suitable in the region of Himesháza too, broadening the utilization of renewable resources.

The realization of the current project could contribute to shifting the energy resource sector in a more modern, environmentally conscious direction.

The background for shorter-term plans and investment (carried out within the framework of operational programs) necessary for the optimal operation and maintenance of longer-term (25–50 years) energy development strategies is created by the analysis (at multiple scales) of complex regional characteristics and future potential, and the selection of optimal sites.

Development of Competition in Regional Markets of Medical Services
Authors: Gorbova Olga
Published: December 2019

The purpose of assessing the level of competition in the market of medical services is achieved through the use of the author’s methodology. The author develops a theoretical model of competition taking into account features of the social sphere on the basis of the received estimates. The method of assessing the level of competition includes two groups of indicators: objective and subjective ones. Objective indicators are based on the use of official statistical information, subjective indicators are based on the data of electronic surveys of service consumers. The paper presents the integral assessment in points and allows to refer the level of competition in the market to one of three categories: weak, moderate or strong competition. According to the results of evaluating, the author points out the problems hindering the development of competition in the market, as well as features that impose restrictions on the potential of forming a competitive environment. These include: high share of public institutions in the market, complexity of working in the system of compulsory health insurance for commercial organizations, lack of real mechanisms for the development of competition on the part of the state. The author presents a theoretical model of development of competition in the market including three levels of medical organizations allocated in accordance with complexity and cost of the process of providing services and conditions implemented by Federal and regional authorities.

Published: December 2019

Background

The effectiveness of second-line palliative chemotherapy in patients with recurrent/metastatic osteosarcoma is not well defined. Several small studies (6–19 patients) have reported on ifosfamide as second-line treatment. In this study we report our single-center experience with second-line ifosfamide monotherapy in patients treated for recurrent/metastatic osteosarcoma.

Methods

A chart review was conducted of all patients with osteosarcoma treated with ifosfamide from 1978 until 2017. Until 1997 a 5 g/m2 regimen was used, and from 1997 onwards a 9 g/m2 regimen was used. Overall survival (OS) from start of ifosfamide was the primary endpoint. Progression-free survival (PFS) from start of treatment was also studied. To assess difference in survival between groups the log rank test was applied. To investigate the effect of ifosfamide dose and World Health Organization performance status (PS) a Cox proportional hazard regression model was estimated.

Results

Sixty-two patients were selected with recurrent/metastatic osteosarcoma treated with second-line ifosfamide monotherapy (dose of 5 g/m2, n = 26; 9 g/m2, n = 36). OS was significantly better in univariate analysis for 9 g/m2 compared with 5 g/m2 (10.9 months [95% confidence interval (CI), 9.3–12.6] vs. 6.7 months [95% CI, 5.9–7.6], respectively) and for PS (median OS PS 0, 13.0 months [95% CI, 2.3–23.8]; PS 1, 8.2 months [95% CI, 5.4–11.1]; PS ≥2, 6.2 months [95% CI, 2.2–10.3]; and unknown PS, 5.4 months [95% CI, 2.2–8.5]). In multivariate analysis only PS showed a significant difference. No difference in PFS was found between 5 and 9 g/m2 ifosfamide treatment or PS.

Conclusion

This study suggests that ifosfamide is an effective second-line treatment for patients with recurrent/metastatic osteosarcoma.

Elektrik direnç punta kaynağı ile birleştirilen %15 deforme edilmiş TWIP çeliğinde kaynak akımının mikroyapı ve mekanik özellikler üzerindeki etkisi
Authors: AYDIN Hakan , TUTAR Mümin , DAVUT Kemal , BAYRAM Ali
Published: December 2019

Çalışmada, %15 deforme edilmiş TWIP saclarının elektrik direnç punta kaynağıyla birleştirmelerinde kaynak akımının mikroyapı ve mekanik özellikler üzerindeki etkisi incelenmiştir. Mikroyapı karakterizasyonunda optik mikroskop, taramalı elektron mikroskobu (SEM), SEM/Enerji dağılımlı X-ışını Spektroskopisi (SEM-EDS) ve SEM/Elektron Geri Saçılım Kırınımı (SEM-EBSD) teknikleri kullanılmıştır. Mekanik özelliklerin belirlenmesinde, mikrosertlik ölçümleri ve çekme testleri yapılmıştır. Kaynak akımı artışı ile erime bölgesindeki kaynak boşlukları azalırken, çekirdek çapı, çökme miktarı ve ısı tesiri altındaki bölge (ITAB) genişliği yaklaşık lineer bir şekilde artmıştır. Kaynak bölgesinde deformasyon ikizleri ortadan kalkarken, ITAB’da iri tavlama ikizleri ortaya çıkmıştır. Ayrıca, kaynak akımı artışıyla ITAB’daki tane irileşmesi ve ikiz kalınlıkları artmıştır. Ancak, kaynak işlemi kaynak bölgesinde herhangi bir faz dönüşümüne neden olmamıştır. Bu sebeple, kaynak bölgesi sertlik değerleri temel malzemenin sertlik değerlerinden oldukça düşük kalmıştır. Genel itibariyle, en düşük sertlikler ITAB’da gözlenmiştir. Kaynak akımı ile kaynak bölgesi sertlik değerleri arasında herhangi bir korelasyon elde edilmemiştir. Kopma yükü kaynak akımı ile artmıştır: En yüksek kopma yükü 10 kA kaynak akımında elde edilmiştir. Düşük kaynak akımlarında aryüzey tipi kırılma meydana gelirken yüksek kaynak akımlarında buton çekirdek tipi kırılmalar ortaya çıkmıştır. Kırılma karakteristikleri genel itibariyle gevrek-sünek karışımıdır. Daha yüksek mukavemete sahip numunelerde gevrek-sünek kırılma bölgesinde sünek kırılma, gevrek kırılma bölgesinde ise trans-granular kırılma karakteristikleri artış göstermiştir.

Published: December 2019

Dış
kaçış merdivenlerinde erişime ve kullanıma yönelik sorunların var olması ve
sürekliliği nedeniyle binalarda yangın güvenliği açısından tehlikeli durumlar
söz konusudur. Bu çalışmanın amacı, dış kaçış merdivenlerindeki tehlike
kaynaklarının ortadan kaldırılması ya da azaltılması ve bu kaynakların
kullanıcılar üzerinde oluşturabileceği zararların önlenmesidir. Çalışmada,
mevcut binalarda bulunan dış kaçış merdivenlerindeki tehlikelerin önlenmesine yönelik
yapılacak düzenlemelerde, hangi tehlike kaynaklarının dikkate alınması
gerektiğini tespit etmek ve çözüm üretmek amacıyla yeni bir risk analizi modeli
önerilmiştir. Bu model, İstanbul’un 10 ilçesinde yapılan alan çalışmasıyla sınanmış
ve dış kaçış merdivenlerindeki risklerin yüksek olduğu belirlenmiştir. Elde
edilen sonuçlar, önerilen modelin dış kaçış merdivenlerinde var olan tehlike
kaynaklarının, bina sayısı ve tehlike düzeyi dikkate alınarak
derecelendirilmesinde ve risklerin analiz edilerek tehlikelere karşı çözümler
üretilmesinde, başarılı bir biçimde kullanılabileceğini göstermiştir.
Linguistics of information-psychological war in the making: methodological heterogeneity and first results
Authors: Kushneruk Svetlana Leonidovna
Published: December 2019

The paper focuses on theoretical and methodological aspects of the development of one of the latest trends in Russian discourse studies – linguistics of information-psychological war. The analysis involves publications, retrieved from Russian electronic library (“Elibrary”) under a thematic subject heading "Linguistics" and "Mass communication", all of which being dedicated to the problems of information confrontation. The main objective is to specify how linguistics of information-psychological war has been developing since 2017, when the research trend was initially proposed by a group of Siberian scholars. Minor task is to determine, what ideas constitute a common around for Russian scholars, that try to unravel the linguistic mechanisms, underlying the complex phenomenon of information-psychological war. Analytical-descriptive approach, including methods of observation, generalization, and interpretation, is employed. It is argued that linguistics of information-psychological war has acquired discursive dimension. It features methodological heterogeneity, recurrence of themes, terminological variability, use of related concepts. It is proved that information-psychological war is treated as a construct, textualized in media discourse. The major theoretical and methodological problem is outlined, which relates to the absence of relevant criteria that could be adequate to identify texts as means of information-psychological war. The results can be used to extend the scope of linguistics of information-psychological war and to increase its capacity for working out the linguistic bases of counteraction to threats in media sphere.

deney ve kontrol gruplarına ön-test ve son-test olarak uygulanmıştır. Deney grubunda bulunan öğretmen adayları küçük gruplar
halinde araştırma, tartışma ve karar verme süreçlerine katılırken, kontrol
grubunda ise büyük grup tartışmalarına dayalı etkinlikler yürütülmüştür. Çalışmadan elde edilen bulgulara göre, hem
deney ve hem de kontrol grubunun eleştirel düşünme eğilimlerinde istatistiksel
olarak anlamlı düzeyde bir artış sağlanmıştır. Ancak, deney grubu
öğrencilerinin eleştirel düşünme eğilimleri, kontrol grubuna oranla anlamlı
düzeyde daha yüksek bir artış göstermiştir.
Epigrafía cristiana de al-Andalus: Mozárabe y latina
Authors: Barcelo Carmen
Published: December 2019

Recuento de las inscripciones latinas y bilingües latín-árabe hasta ahora conocidas, labradas por cristianos de la Península Ibérica bajo el gobierno islámico. Las inscripcciones latinas se concentran en las ciudades y son escasas en las áreas rurales; en su gran mayoría son epitafios y apenas se registran sobre objetos litúrgicos. El trabajo analiza por primera vez la posibilidad de que pertenezcan a cristianos algunos epígrafes solo en árabe.
El castillo de Peñas de San Pedro (Albacete) en la Edad Media
Authors: González Ballesteros José Ángel , Soria Combadiera Lucía , Lucendo Díaz Diego
Published: December 2019

La Peña del Castillo (Peñas de San Pedro, Albacete) es un yacimiento arqueológico de gran interés por constatarse una dilatada ocupación desde el Bronce Final al siglo XIX. El proyecto de actuaciones arqueológicas, iniciado en 2016, pretende conocer los diferentes modelos de poblamiento a lo largo de su ocupación. La Edad Media constituye uno de los periodos más significativos de esta evolución temporal a nivel material. El promontorio rocoso donde se asienta el actual “castillo”, fue base de las comunidades campesinas andalusíes y germen del núcleo urbano de la actual población, adscrita al concejo de Alcaraz durante la Baja Edad Media hasta su segregación como villa en el año 1537. El presente trabajo sintetiza el estado actual de los datos disponibles sobre el asentamiento andalusí y el análisis de algunos elementos que caracterizan el perímetro amurallado, centrándonos en el acceso septentrional del recinto medieval.
The Utilisation of Migrant Capital to Access the Labour Market: The Case of Swedish Migrants in Helsinki
Authors: Wahlbeck Östen , Fortelius Sabina
Published: December 2019

This article explains from a Bourdieusian perspective how migrants gain access to fields in which their resources are valued and their cultural and social capital can be mobilised. Interviews conducted among Swedish migrants in Helsinki (Helsingfors) illustrate how the migrants have been able to utilise various forms of capital to gain access to the local labour market. Knowledge of the Swedish language and society may constitute cultural capital, but only in specific occupations and social contexts. The article highlights the importance of access to social networks among Finnish spouses and friends in finding information about the jobs in which knowledge of the Swedish language and society is valued. The results indicate that the resources of migrants do not always constitute a valuable social capital, migrants also need to be able to mobilise their resources in a given social context. It is also argued that there may be specific forms of cultural and social capital that are only available to migrants as a consequence of their being migrants. This migrant capital consists of the various forms of capital that are connected to the migration process and are mobilisable by the migrants.
Transnational Social Capital in Migration: The example of Educational Migration between Bulgaria and Germany
Authors: Glorius Birgit
Published: December 2019

Focusing on student migration from Bulgaria to Germany, this article examines what types of social capital are accumulated, transformed and implemented through migration, who profits from the investment, and how. The empirical work consists of 60 narrative biographical interviews with migrants and returnees to Bulgaria. The research reveals that the accumulation and investment of social capital takes place throughout the migratory trajectory—starting well before leaving—and is embedded in a transnational social space. Transnational networks exist as family, peer and professional networks, and all of them have a specific meaning for the migrants. Family networks are naturally present; they provide bonding social capital and thus have a stabilizing function for the individual’s identity. Professional networks have a strongly bridging function, helping the young migrants to manage status transitions. After return the transnational social capital acquired during the migratory stay helps returnees to re-integrate and find their way into the Bulgarian labour market. It also encourages them to pursue activities which are meaningful for civil society development, or for innovative (social) entrepreneurship. Thus, transnational social capital helps migrants to align their biographical development to the future, considering the post-transformative environment of Bulgaria, thereby helping to manage transformative changes and supporting societal modernization processes.
“Poesia é vertical”: Samuel Beckett e a criatividade vanguardista
Authors: Kempinska Olga
Published: December 2019

Ao debruçar-se sobre o envolvimento de Samuel Beckett no surrealismo, evidenciado pela assinatura, em 1932, do manifesto “Poesia é vertical”, e culminado em Murphy, o artigo tenta resgatar alguns traços da teoria do sublime de Burke na visão vanguardista da criatividade. A acentuação da verticalidade subverte não apenas a experiência desencarnada do sublime, tal como conceituado na estética tradicional, como também insiste em sua reinterpretação no âmbito da psicanálise, permitindo, dessa forma, a elaboração de uma reflexão sobre o prazer do trabalho da escrita e sobre a relevância da destruição nos processos criativos. Constituindo uma resposta ao Segundo Manifesto do Surrealismo (1930), permeado pela violência, e coincidindo com a reformulação freudiana do processo da sublimação, no qual acontece a troca não apenas da direção da pulsão, mas também de seu objeto, o manifesto conta ainda com a assinatura de Hans Arp, abrindo-se, assim, a uma discussão sobre a importância da relação entre os regimes visual e verbal.
“Dearest Reader, It’s Up to You”: Articulating the Theory of Aesthetic Response and Metafiction in Ian McEwan’s Sweet Tooth
Authors: Nóbrega Caio Antônio , Azerêdo Genilda
Published: December 2019

In this paper, we aim at discussing the figure of the reader and the reading processes in Ian McEwan’s novel Sweet Tooth. To do so, we propose an articulation between the theoretical discourses on metafiction and the theory of aesthetic response. Drawing from theoretical frameworks elaborated mainly by Iser (1972, 1978, 1989, 2006) – regarding the theory of aesthetic response – and by Hutcheon (1980, 2000) and Waugh (1984) – regarding metafiction – we understand parody and mise en abyme as two metafictional procedures that constitute the structure of the implied reader. In this sense, if these metafictional creative strategies make the reading activity more complex, they also function as guiding systems to the reader, allowing him to pursue answers to the enigmas articulated within the novel. Parody and mise en abyme, for McEwan, are powerful tools in what we might perceive as a project to develop more proficient readers.
“Your Words and Your Performances Are no Kin Together”: um estudo sobre o clown do teatro shakespeariano
Authors: De Freitas Coachman Erika
Published: December 2019

Formado pela fusão de ator e personagem, o clown do palco shakespeariano não se submetia à tirania do script: sua atuação era marcada por improvisos e interações com o público. O presente artigo busca transcender a análise do texto dramático para lançar luz sobre ele, uma criatura do teatro elisabetano-jaimesco que desafiava e reinventava a peça concebida por seu criador. No espaço liminal entre palco e realidade, sua performance cômica roubava a cena, tornando a experiência teatral inescapavelmente imprevisível.
Uma alavanca em direção ao fim do mundo: H. G. Wells e sua máquina do tempo
Authors: Iachtechen Fabio Luciano
Published: December 2019

A máquina do tempo, primeiro romance do escritor inglês H. G. Wells, foi, desde seu lançamento em 1895, um importante sucesso editorial, além de ter se tornado uma das mais representativas obras precursoras da moderna ficção científica. Uma de suas características essenciais é a proposta de uma viagem temporal proporcionada pela ação humana, com base no conhecimento de sua época. Ao dialogar com as premissas científicas em voga Wells criou não apenas uma máquina, mas também um conjunto de possibilidades acerca da relação humana com o tempo, concebido não mais aprioristicamente como um dado natural, mas conjecturado como um elemento possível de ser apreendido e moldado pela ação humana. Neste artigo, proponho analisar a máquina de viajar no tempo como uma criação wellsiana e discutir tanto as bases materiais e científicas que a acompanharam, bem como uma concepção histórico-filosófica acerca do tempo enquanto experiência humana concreta.
