Distribution of temperature coefficient density for muons in the atmosphere
Authors: Кузьменко Василий , Kuzmenko Vasiliy , Янчуковский Валерий , Yanchukovsky Valery
Published: December 2017

To date, several dozens of new muon detectors have been built. When studying variations in cosmic-ray intensity with these detectors, located deep in the atmosphere, it is necessary to calculate all characteristics, including the distribution of temperature coefficient density for muons in the atmosphere, taking into account their specific geometry. For this purpose, we calculate the density of temperature coefficients of muon intensity in the atmosphere at various zenith angles of detection at sea level and at various depths underground for different absorption ranges of primary protons and pions in the atmosphere.
Information Systems Projects and Individual Developer Outcomes: Role of Project Managers and Process Control
Authors: Venkatesh Viswanath , Rai Arun , Maruping Likoebe M.
Published: December 2017

We integrate control theory and the information systems (IS) project management literature using a multilevel lens to theorize the cross-level effects of technical IS project risk on individual developer outcomes—performance and psychological stress—and the mechanisms by which IS project managers’ project-related knowledge attenuates this relationship. We argue that IS project managers with project-related knowledge mitigate technical IS project risk by facilitating the enactment of internal and external process controls in their IS projects. Our empirical study involves data collected from 1,230 individual developers embedded in 130 IS project teams that are managed by 20 IS project managers. Our results provide strong support for the three-level model and its set of (a) cross-level main effects of technical IS project risk on individual developer outcomes; (b) cross-level main effects of IS project manager project-related knowledge on enacted internal and external process controls; and (c) cross-level moderation of the relationship between technical IS project risk and individual developer outcomes by IS project manager project-related knowledge through internal and external process controls. Our study provides insights on how IS project management, IS project process controls, and technical IS project risk must be managed as a system of multilevel dependencies to achieve the desired developer outcomes.

Simulating Macro-Level Effects from Micro-Level Observations
Authors: Smith Edward Bishop , Rand William
Published: December 2017

We consider the fruits of integrating agent-based modeling (ABM) with lab-based experimental research with human subjects. While both ABM and lab experiments have similar aims—to identify the rules, tendencies, and heuristics by which individual agents make decisions and respond to external stimuli—they work toward their common goal in notably different ways. Behavioral-lab research typically exposes human subjects to experimental manipulations, or treatments, to make causal inferences by observing variation in response to the treatment. ABM researchers ascribe individual simulated “agents” with decision rules describing their behavior and subsequently attempt to replicate “macro” level empirical patterns. Integration of ABM and lab experiments presents advantages for both sets of researchers. ABM researchers will benefit from exposure to a larger set of empirically validated mechanisms that can add nuance and refinement to their models of human behavior and system dynamics. Lab-oriented researchers will gain from ABM a method for assessing the validity and magnitude of their findings, adjudicating between competing mechanisms, developing new theory to test in the lab, and exploring macro-level, long-run implications of subtle, micro-level observations that can be difficult to observe in the field. We offer an example of this mixed-method approach related to status, social networks, and job search and issue guidance for future research attempting such integration.

REFLECTIONS ON PRIORITIZING DIVERGENT INTANGIBLE HUMANE ACTS
Authors: Shang Jennifer
Published: December 2017

AHP is a versatile tool for prioritizing and making decisions.  Yet, when facing numerous alternatives with significantly different scale, decision makers often found it impossible to put them together in one matrix and compare them simultaneously. To address the issue, Thomas Saaty and I (2011) proposed a new Analytic Hierarchy Process-based structure to capture the complex relationship between various levels of activities. Without the proposed model, we may not be able to tackle alternatives that are not comparable or it may require a very large number of comparisons, as only comparable items can be compared and used to calculate meaningful priorities. In this paper, we show how to use clustering and pivots to handle this difficulty. Through the proposed method, we expand the comparison scale, build a near-consistent matrix, and allow the use of incomparable alternatives.  The proposed method helps us effectively derive priorities for alternatives with orders-of-magnitude differences like those in divergent intangible humane acts.https://doi.org/10.13033/ijahp.v9i3.536

Autonomy Support, Need Satisfaction, and Motivation for Support Among Adults With Intellectual Disability: Testing a Self-Determination Theory Model
Authors: Frielink Noud , Schuengel Carlo , Embregts Petri J. C. M.
Published: December 2017

The tenets of self-determination theory as applied to support were tested with structural equation modelling for 186 people with ID with a mild to borderline level of functioning. The results showed that (a) perceived autonomy support was positively associated with autonomous motivation and with satisfaction of need for autonomy, relatedness, and competence; (b) autonomous motivation and need satisfaction were associated with higher psychological well-being; (c) autonomous motivation and need satisfaction statistically mediated the association between autonomy support and well-being; and (d) satisfaction of need for autonomy and relatedness was negatively associated with controlled motivation, whereas satisfaction of need for relatedness was positively associated with autonomous motivation. The self-determination theory provides insights relevant for improving support for people with intellectual disability.
Later Life Impacts of Social Participation on Parents of Adult Offspring With and Without Intellectual and Developmental Disabilities
Authors: Olsen Darren L. , Floyd Frank J. , Mailick Marsha R. , Greenberg Jan S.
Published: December 2017

Social participation is an important resource for parents in old age, and may be particularly important for parents living with adult offspring with intellectual and developmental disabilities. To evaluate whether socializing with friends and family and participating in social organizations protects against depression in old age, this study examined parents of adult offspring with disabilities (n = 164) and without disabilities (n = 820). As expected, more socializing with friends and more participating in organizations were associated with fewer depressive symptoms for all parents. However, socializing with family members predicted fewer depressive symptoms only for parents co-residing with their adult offspring with disabilities, suggesting that socializing with family is particularly important for parents providing direct care to adults with disabilities.

Published: December 2017

Introducción:

La Discitis o Espondilodiscitis es una entidad poco frecuente en pediatría, la cual, en términos de fisiopatología y manifestaciones clínicas, es muy controvertida.  Se presenta un reporte de caso, de una paciente de 3 años, quien consulta al servicio de urgencias por presentar marcha antálgica progresiva. Se hizo un enfoque diagnóstico inicial mediante una resonancia magnética nuclear (RMN) que reporto una Espondilodiscitis. Se dio tratamiento integral con antibioticoterapia y antiinflamatorio, logrando una evolución satisfactoria.

Presentación del caso:

Paciente de 3 años de edad, de sexo femenino, quien consulto por cuadro clínico de 20 días de evolución, consistente en marcha antálgica progresiva asociada a irritabilidad, signos y síntomas ventilo-respiratorios, sin antecedentes de importancia. Ante hallazgos clínicos e imageneológicos se realizó el diagnóstico de Espondilodiscitis. Se inició antibioticoterapia, manejo antiinflamatorio y, adicionalmente, se ordenó reposo y rehabilitación física. La paciente evolucionó de manera satisfactoria por lo cual se dio egreso hospitalario.

Conclusiones:

Aun cuando la Espondilodiscitis es una patología poco frecuente y auto-limitada, es importante tenerla en cuenta entre los diagnósticos diferenciales debido a sus potenciales complicaciones. La resonancia magnética es el estándar de oro para el diagnóstico temprano. El tratamiento integral incluye reposo en cama inicial, antiinflamatorios, en algunos casos, antibioticoterapia y rehabilitación física.
EFECTO DE DIETAS EN ADULTOS DE Spodoptera cosmioides (LEPIDOPTERA: NOCTUIDAE) SOBRE LA FERTILIDAD, FECUNDIDAD Y LONGEVIDAD DEL ADULTO

Published: December 2017

La aparición de cultivares de soja Bt + RR2Y determinó la emergencia de una nueva plaga, Spodoptera cosmioides, una plaga altamente polífaga de amplia distribución. La cría de insectos en cámaras de cría es necesaria para estudios de investigación básica y aplicada. El objetivo del trabajo fue evaluar el efecto de tres dietas ricas en carbohidratos (solución de miel, de jarabe de glucosa y de jarabe de maíz) en la alimentación de los adultos y determinar su efecto sobre la fecundidad, fertilidad y supervivencia de S. cosmioides. Se determinó que, si bien no se hallaron diferencias entre los tratamientos, la composición de los  azúcares de las dietas, puede afectar los parámetros reproductivos de esta plaga, ya que las hembras alimentadas con solución de miel natural, más rica en compuestos orgánicos, aumentaron la fecundidad, refl ejado en una mayor puesta y eclosión de huevos y la longevidad de los adultos.

Published: December 2017

Se evaluaron métodos para superar la dormición y determinar las necesidades de luz en la germinación de Juglans nigra. Para superar la latencia y dureza del endocarpio se realizó Estratificación en caliente (T1), Inmersión en ácido giberélico (T2) y Estratifi cación en frío húmedo (T3). Para la necesidad de luz se evaluó alternancia de oscuridad/luz y oscuridad permanente. Se analizó el Porcentaje Germinación (% de G), Índice Velocidad de Germinación (IVG), Tiempo Medio Germinación Máxima (TMG), % Plántulas Normales, % Semillas sin germinar, Peso Seco Medio de plántulas (PSM) y el Índice de Germinación Relativo a la luz (GRL). En T1 no hubo germinación y en T2 irrelevante. T3 produjo diferencias altamente significativas en todas las variables analizadas, siendo el período de 4 meses de estratifi cación el mejor para romper la dormición. Al no ser la luz un factor determinante en la germinación, esta especie se clasifi caría como fotoblástica neutra.

Published: December 2017

The Computer-Aided Dispatch (CAD) system is an essential element of public safety to streamline the emergency response process and enable real-time information sharing. With the introduction of Next Generation 9-1-1 (NG9-1-1), there is great potential to enhance the functionalities and capabilities of the conventional CAD system. However, the transition to NG9-1-1 and the implementation of the Next Generation CAD (NGCAD) system are both challenging and very slow owing to many constraints. This paper aims to explore and discuss the current challenges and future trends that have an impact on developing and implementing NGCAD. More specifically, it highlights current technological and non-technological challenges associated with NG9-1-1 and outlines how the emerging technologies can help in resolving them. We predict that this paper will benefit all CAD system stakeholders, including public safety and industry professionals, by increasing the awareness of the NGCAD system’s evolution and the capabilities it is required to have within the context of NG9-1-1.
Asociaciones africanas en Cataluña: fortalezas y debilidades
Authors: Llevot Calvet Nuria , López Teulón María Paz
Published: December 2017

La evolución del fenómeno migratorio en España ha comportado, entre otras cuestiones, el continuo crecimiento de organizaciones creadas por inmigrantes. Este aumento se produce, por una parte, por el interés de los propios africanos y, por otra, por la voluntad que tienen los representantes de las administraciones de generar interlocutores que faciliten el contacto con los inmigrantes. Asimismo son fundamentales las posiciones que adoptan las diferentes políticas (estatales y autonómicas) al condicionar los papeles que desempeñan las asociaciones de inmigrantes. Este estudio[1] en cuya realización se ha empleado metodología cualitativa (entrevistas en profundidad) con una perspectiva territorial abarca toda Cataluña, centra el objeto de estudio en la inmigración y el asociacionismo de los inmigrantes africanos y, más particularmente, en as necesidades que tienen y en las demandas que dirigen a instituciones públicas y privadas.

[1] Este estudio forma parte del proyecto I + D dirigido por Jordi Garreta (UdL), titulado “Asociacionismo e inmigración africana: funciones latentes y manifiestas” financiado por el Ministerio de Ciencia e Innovación (CSO2008-01122/SOCI) y centrado en las comunidades de Cataluña, Valencia y Navarra.

Published: December 2017

Este texto reflexiona sobre el papel de la prensa española en la comercialización sexual de mujeres a través de la publicidad de contactos que insertan en sus páginas, tomando como punto de partida una muestra de 860 anuncios aparecidos en los principales diarios españoles durante 2016. De una parte, se analizan las claves del discurso publicitario de la prostitución, que presenta como rasgos principales la  hipersexualización de los atributos físicos de las mujeres, la reproducción de los roles tradicionales de género y la racialización-etnificación de la oferta, que se relaciona con la intensificación de los flujos migratorios dirigidos  a España. De otra parte, se presenta el debate ético-jurídico sobre esta clase de publicidad, inexistente en la prensa europea de referencia, pero generalizada en los periódicos españoles

Morphological responses of the Wax Lake Delta, Louisiana, to Hurricanes Rita

Published: December 2017

This study examines the morphodynamic response of a deltaic system to extreme weather events. The Wax Lake Delta (WLD) in Louisiana, USA, is used to illustrate the impact of extreme events (hurricanes) on a river-dominated deltaic system. Simulations using the open source Delft3D model reveal that Hurricane Rita, which made landfall 120 km to the west of WLD as a Category 3 storm in 2005, caused erosion on the right side and deposition on the left side of the hurricane eye track on the continental shelf line (water depth 10 m to 50 m). Erosion over a wide area occurred both on the continental shelf line and in coastal areas when the hurricane moved onshore, while deposition occurred along the Gulf coastline (water depth < 5 m) when storm surge water moved back offshore. The numerical model estimated that Hurricane Rita’s storm surge reached 2.5 m, with maximum currents of 2.0 m s–1, and wave heights of 1.4 m on the WLD. The northwestern-directed flow and waves induced shear stresses, caused erosion on the eastern banks of the deltaic islands and deposition in channels located west of these islands. In total, Hurricane Rita eroded more than 500,000 m3 of sediments on the WLD area. Including waves in the analysis resulted in doubling the amount of erosion in the study area, comparing to the wave-excluding scenario. The exclusion of fluvial input caused minor changes in deltaic morphology during the event. Vegetation cover was represented as rigid rods in the model which add extra source terms for drag and turbulence to influence the momentum and turbulence equations. Vegetation slowed down the floodwater propagation and decreased flow velocity on the islands, leading to a 47% reduction in the total amount of erosion. Morphodynamic impact of the hurricane track relative to the delta was explored. Simulations indicate that the original track of Hurricane Rita (landfall 120 km west of the WLD) produced twice as much erosion and deposition at the delta compared to a hurricane of a similar intensity that made landfall directly on the delta. This demonstrates that the wetlands located on the right side of a hurricane track experience more significant morphological changes than areas located directly on the hurricane track.

Published: December 2017

Biodiesel is typically made by chemically reacting lipids of palm, vegetable, and waste cooking oils and animal fat with an alcohol producing fatty acid esters. Biodiesel is not efficient in cold weather and this is biodiesel’s major problem. Viscosity has influences on the fuel flow rate and leads to poor fuel atomisation during the combustion process. The aim of this study is to determine the effects of biodiesel temperature in the range fom 40 °C and 60 °C on engine performance such as torque, brake power, brake mean effective pressure, and fuel consumption. Three types of biodiesel oil were used (crude palm oil (CPO), waste cooking oil (WCO), and jatropha oil) under biodiesel blending ratio of 5vol%. A single cylinder four-stroke engine was used and operated under different load conditions of 0% and 50% and observed emission of CO, CO2, NOx, and HC. The engine operated at 0% and 50% dynamometer load conditions and running speeds of the engine of 800 rpm, 1200 rpm, 1600 rpm, and 2000 rpm. The results of this study showed that the heating temperatures in the range from 40 °C and 60 oC in CPO10 produced the highest brake power as well as torque and BMEP. For the experimental results of exhaust emission, the preheated temperature affected the degradation of the exhaust emission. In addition, preheated biodiesel increased the pressure on the cylinder combustion chamber. It can be concluded that the biodiesel preheated blend influences the performance and emission. For CPO biodiesel, the preheated biodiesel decreased CO and NOx while the standard diesel produced the lower emission of CO2 and HC. WCO biodiesel blend produced a lower emission with increasing fuel temperature.

Authors: Satheesh Kumar B. , Padmanabhan G. , Vamsi Krishna P.
Published: December 2017

This paper aims to obtain the optimal combination of machining parameters for multiple performance characteristics in the turning operation by implementing desirability function analysis. Experiments were conducted using machining parameters like different proportions (5%, 10%, and 15%) of extreme pressure additive in three different vegetable oil based cutting fluids (sesame, canola, and coconut oils), cutting speed and feed rate for evaluating the cutting force, cutting tool temperature, tool flank wear, and surface roughness. An orthogonal array (L27) was generated using the Taguchi design to carry out the experiments on AISI 1040 steel. Composite desirability was analysed for identifying the optimal levels of machining parameters. Experimental results revealed that cutting fluid had the most significant effect on cutting force, cutting tool temperature, tool flank wear, and surface roughness. Confirmation test was carried out to validate the results. Experimental results have shown that machining performance can be improved through desirability function analysis.
Investigation of surface roughness and material removal rate for UD-GFRP composite using Taguchi grey relational analysis
Authors: Kumar Surinder , Meenu
Published: December 2017

In this paper, a grey relational method was used for minimising surface roughness and  maximising material removal rate during turning of unidirectional glass fibre reinforced plastic composite (UD-GFRP). Taguchi approach was used for the experiment. The parameters studied were tool rake angle, speed, depth of cut, feed, tool nose radius, and cutting environment. Castrol water (1:6) miscible soluble coolant was flooded in the machining zone. Cutting environment: Wet (33°-38°c) and Cold (5°-7°c) were used. The Taguchi L18 orthogonal array was used for performing the experiment. Significant parameters were found by applying ANOVA. The grey relational analysis was used to optimise the parameters affecting the response. Cutting speed was the factor, followed by feed rate that influenced surface roughness and material removal rate. The surface roughness of 1.761 µm and material removal rate of 275.78 mm3 were achieved.
Investigation and optimization for the dynamical behaviour of the vehicle structure
Authors: Zargar Omid , Masoumi Abolfazl , Moghaddam Amir Ostadi
Published: December 2017

Conceptual modelling is known as a well suited alternative approach for Computer-Aided Engineering (CAE) analysis in automotive industry. In this paper, an improved conceptual modelling method in which beams and panels of the structure are modelled as simplified beam elements has been proposed. To explore the advantage of conceptual modeling in determining the resonant frequencies/mode-shapes, a case study for wheelhouse was performed. Firstly, an experimental test and advanced CAE analysis were carried out to measure the wheelhouse dynamic characteristics. The advanced CAE model was then validated by means of Modal Assurance Criterion and natural frequencies by associated experimental measurements. The results of wheelhouse concept model compared to the advanced CAE and experimental model in low frequency range, showed that the error percent of natural frequency is lower than 10% and the Modal Assurance Criterion is above 0.75 for the first four mode shapes of wheelhouse structure. Finally, the conceptual model is used as a baseline for optimization. The genetic algorithm was implemented to maximize the first natural frequency to 41.74 Hz. So The genetic algorithm successfully provided new possibility for optimization by attempting to influence the first mode shape by means of the cross section characteristics. Due to the accuracy and reliability of developed conceptual model, this modelling approach can be a crucial tool in CAE and vibration analysis of vehicle in the early design phase. The proposed method allows the designer to give the results of design changes very quickly by neglecting details. Therefore, for the analysis of the vehicle performance in NVH domain, the proposed method could be considered in the conceptual design phase.

Published: December 2017

The volume that the root system can occupy is associated with the efficiency of water and nutrient uptake from soil. Genetic improvement of root length, which is a limiting factor for root distribution, is necessary for increasing crop production. In this report, we describe identification of two quantitative trait loci (QTLs) for maximal root length, QUICK ROOTING 1 (QRO1) on chromosome 2 and QRO2 on chromosome 6, in cultivated rice (Oryza sativa L.). We measured the maximal root length in 26 lines carrying chromosome segments from the long-rooted upland rice cultivar Kinandang Patong in the genetic background of the short-rooted lowland cultivar IR64. Five lines had longer roots than IR64. By rough mapping of the target regions in BC4F2 populations, we detected putative QTLs for maximal root length on chromosomes 2, 6, and 8. To fine-map these QTLs, we used BC4F3 recombinant homozygous lines. QRO1 was mapped between markers RM5651 and RM6107, which delimit a 1.7-Mb interval on chromosome 2, and QRO2 was mapped between markers RM20495 and RM3430-1, which delimit an 884-kb interval on chromosome 6. Both QTLs may be promising gene resources for improving root system architecture in rice.
Psychosocial work environment and oxidative stress among nurses’
Authors: Salem Eman A , Ebrahem Sabah M
Published: December 2017

Background

Work stress among nurses has increased in recent years due to the demands of clinical nursing.

Objectives

To investigate psychosocial work stress among nurses using the effort-reward imbalance (ERI) model with assessment malondialdehyde (MDA) as an oxidative stress marker and total antioxidants.

Methods

The present study was conducted on 204 registered nurses worked at two tertiary hospitals in Menoufia governorate, Egypt through the period from the 1st of February to the end of July 2016. Two questionnaires were applied including general demographic and occupational histories as well as effort-reward questionnaire. Blood analysis was performed to assess MDA and total antioxidant levels.

Results

ERI was prevalent among the study participants (72.5%). ERI was more prevalent among young married nurses who worked more than 10 years. Nurses that worked at ICUs complained more of ERI (43.2%) while nurses that worked at operation rooms complained more of overcommitment (62.5%). MDA levels were significantly positively correlated with E/R ratios (rho = 0.350, P ≤ 0.001).

Conclusions

Work stress was prevalent among the studied nurses as revealed by the high ERI and MDA levels. Young married female nurses complained more of work stress. ICUs and operating rooms were the most stressful departments at the studied hospitals. Hence, implementing programs and strategies that eliminate stressful working conditions at hospitals is critical to the reduction and prevention of work stress among nurses.

Methods: It was an observational, cross-sectional, quantitative study, which evaluated 97 records of the elderly outpatient from Single HealthSystem of the Institute of Geriatrics and Gerontology (IGG) and the University Extension Center (UEC) Villa Fatima, Porto Alegre/RS from 2008 to 2009.Results: The results revealed that the lack of understanding might be related to the progression of age of the population. The prescription understanding ofthe patients attending the IGG was higher when compared to the elderly who attended the UEC (p<0.05). The parameters of blood pressure and dyslipidemiaare not directly correlated to the understanding of the prescription. Conclusions: Thus, it is necessary to work towardsfollowing of pharmacotherapyfrom elderly patients to improve therapy adhesion in this population.

Novela ou romance? A construção da narrativa contemporânea Opisanie Swiata na era da multiplicidade
Authors: Junior Cloves Da Silva
Published: December 2017

Este artigo apresenta uma análise da obra Opisanie Świata (2013), de Veronica Stigger, com enfoque para a construção dessa narrativa. As discussões são direcionadas, primeiramente, em torno das teorias sobre novela e romance, no intuito de perceber as características da narrativa que apontam igualmente para esses dois gêneros. Em seguida, a ideia de contemporâneo, desenvolvida por Agamben (2009), será vinculada à obra, ao mesmo tempo em que se discute a presença da narrativa na era da multiplicidade, baseada nas concepções teóricas de Resende (2008). Trata-se de uma pesquisa bibliográfica com base nos postulados de Bakhtin (2010), Carneiro (2005), Eikhenbaum (1971), Soares (2007), dentre outros. Por meio da análise, o texto apresenta a obra de Stigger como uma narrativa híbrida, resultante da fusão entre romance e novela, bem como indica os pontos que caracterizam a obra como pertencente à era da multiplicidade, juntamente com os aspectos da ideia de contemporâneo.
Malinche e a narrativa histórica feminina no século XXI
Authors: Ribeiro Fernanda Aparecida
Published: December 2017

A literatura de autoria feminina tem registrado ultimamente experiências de personagens femininas que transitam entre as esferas privadas e públicas, com o objetivo de desmascarar a subordinação da mulher legitimada pela ideologia patriarcal e pela literatura canônica. Nesse cenário, algumas escritoras têm se destacado na ficção por resgatar figuras históricas que foram esquecidas ou silenciadas ao longo do tempo por uma realidade arbitrária e por um discurso que valoriza o masculino em detrimento ao feminino. Nesse trabalho, o destaque é a personagem Malinche, uma indígena que acompanhou Hernán Cortés na Conquista do México e ficou conhecida como a traidora de seu povo. O objetivo desse estudo é apresentar as reflexões e a versão do passado que Laura Esquivel oferece em seu romance Malinche (2006), emaranhando os discursos histórico e literário e fazendo com que sua obra provoque o diálogo com a história de forma “transgressora”, pois implica novas visões sobre o discurso instaurado (TROUCHE, 2006). A autora torna-se, assim, uma expoente da literatura escrita por mulheres como sujeitos próprios de seu discurso e que tem como propósito desconstruir o discurso histórico oficial, ao apresentar uma personagem feminina consciente de seus atos e palavras.
Avaliação do uso variável das vogais pretônicas: estudos preliminares de crenças e atitudes
Authors: Avelheda Anna Carolina Da Costa , Da Silveira Eliete Figueira Batista , De Souza Silvia Carolina Gomes
Published: December 2017

A presente pesquisa conjuga os pressupostos da sociolinguística variacionista e a metodologia de análise de crenças e atitudes linguísticas, baseando-se em corpora sociolinguisticamente estratificados de falantes do Rio de Janeiro para analisar o alteamento das vogais médias pretônicas. Primeiramente, focalizamos os casos de especialização semântica. Por meio de um questionário fonético fonológico e de um questionário de percepção, observamos como os usuários da língua produzem os itens cujos sentidos podem influenciar na escolha da variante pretônica. A hipótese é a de que o alteamento tende a ocorrer na expressão de significados menos valorizados (VIEGAS, 1987). No segundo estudo, o teste de atitude compõe-se de três técnicas para observar: (i) na leitura de texto, se o informante realiza o alteamento ao ler determinadas palavras no texto; (ii) na entrevista, a avaliação subjetiva do falante em relação ao fenômeno; e (iii) no questionário, se o julgador é afetado pelo teste de percepção anteriormente realizado. Os resultados de ambos os estudos evidenciam relativa avaliação negativa do uso das variantes alteadas, diferentemente do que mostram os trabalhos que focam exclusivamente os fatores condicionantes.
Estudo sociolinguístico da concordância verbal de 3ª pessoa do plural no português de São Tomé e Príncipe
Authors: Vieira Silvia Rodrigues , Silva Karen Cristina da
Published: December 2017

Com o objetivo de verificar a existência de uma regra variável na concordância verbal de terceira pessoa do plural no Português de São Tomé e Príncipe, consoante a Teoria da Variação e Mudança, este estudo investiga as motivações linguísticas e extralinguísticas que atuam sobre o fenômeno. Partindo do princípio da heterogeneidade ordenada, foi feita a análise multivariada dos dados coletados de entrevistas sociolinguísticas do corpus VAPOR. Os resultados obtidos pelo programa computacional GOLDVARB-X foram interpretados à luz de hipóteses previamente levantadas, com especial atenção aos fatores relacionados ao multilinguismo, fortemente presente na região. Em correlação com outras variedades do Português, os resultados mostram tendências de preferência expressiva pela concordância, sugerindo adoção do modelo europeu. No entanto, os índices obtidos aproximam-se daqueles encontrados em trabalhos sobre a variedade urbana brasileira, o que permite a constatação de uma regra variável na variedade são-tomense. Além disso, observou-se a forte atuação dos fatores extralinguísticos sobre o fenômeno, fato que indica mais semelhanças com a variedade brasileira e pode, futuramente, trazer hipóteses sobre as situações de multilinguismo e a relação deste com a simplificação da morfologia verbal.
Análise variacionista da ditongação crescente na fala popular de Salvador
Authors: Silva Eleneide De Oliveira , Gayer Juliana Ludwig
Published: December 2017

Este artigo apresenta uma parte dos resultados encontrados dentro de uma pesquisa maior, que analisou todos os contextos possíveis de ditongação entre palavras, casos de ditongação crescente e decrescente. Para este trabalho, selecionamos os resultados referentes apenas à análise variacionista da ditongação crescente na fala popular de Salvador. Entre palavras, a ditongação crescente pode ocorrer entre a vogal final de uma palavra e a vogal inicial de outra palavra na sequência, quando a primeira vogal for foneticamente alta e átona. Nesse caso, a primeira vogal se torna glide com a aplicação do processo, como no exemplo tre[zja]nos (treze anos). O objetivo desta pesquisa é contribuir com uma descrição mais detalhada da ditongação crescente que ocorre no português brasileiro, considerando dados da fala popular de Salvador, retirados do banco PEPP (Programa de Estudos sobre o Português Popular Falado de Salvador), coordenado pela Professora Norma Lopes (UNEB). Selecionamos desse banco de dados oito entrevistas classificadas por sexo (masculino e feminino), escolaridade (fundamental e médio) e idade (25 a 35 e mais de 65), totalizando 1.121 dados para a análise estatística. Os dados referentes à ditongação crescente passaram pela análise estatística do Goldvarb X, levando em consideração algumas variáveis já analisadas em outras pesquisas. Dentre os fatores favorecedores à aplicação do processo, encontramse V2 central e tônica, contexto seguinte preenchido por consoante, combinação de vogais altas diferentes e domínio do grupo clítico.
Por uma variável morfossintática: delimitações teóricas e aplicadas à expressão de passado no espanhol
Authors: Araujo Leandro Silveira de
Published: December 2017

Este trabalho visa avaliar como a definição de variável linguística pode se ajustar ao estudo da variação entre as formas do pretérito perfecto em variedades diatópicas da língua espanhola. Para tanto, partimos do percurso epistemológico que envolve a definição do conceito dentro do quadro teórico da Teoria da Variação e Mudança linguística. Em seguida, tratamos especificamente do estudo das formas do pretérito perfecto, mostrando como a norma-padrão define o contexto de uso categórico da forma simpes (canté) e composta (he cantado) e como os estudos descritivos apresentam possibilidades variáveis de uso das mesmas formas. Frente ao cenário de variação, propomos aplicar o conceito de variável linguística apenas àqueles contextos de uso em que ambas as formas expressam efetivamente o mesmo valor, isso é, em que tenham as particularidades neutralizadas no discurso.
Línguas em contato e diversidade linguística: o léxico regional na música gauchesca
Authors: Silva dos Santos Odair José
Published: December 2017

A diversidade de línguas no mundo possibilita que muitas delas estejam em constante contato ou mesmo convivendo emum mesmo espaço, resultando também em interculturalidade. Cria-se, então, a necessidade de promover ações que sejam capazes não só de “ler” essas diferentes realidades, mas também de valorizar e preservar as línguas e suas respectivas culturas, sendo a escola a principal promotora dessas ações. No Rio Grande do Sul, como produto cultural e manifestação da representação de tradições, as músicas gaúchas carregam muitas marcas culturais e linguísticas: vivências de fronteira, vida no campo, fatos da história, além de empréstimos da língua espanhola para a língua portuguesa. Como exemplo, destacamos as produções de César Oliveira e Rogério Melo, que servirão como corpus para a presente investigação. O contato linguístico vai além do mero contato entre duas línguas, provocando intercâmbios entre culturas também e, desse modo, os sujeitos envolvidos acabam por “incorporar” tanto os aspectos linguísticos como culturais. Assim, a presente proposta pretende discutir a noção de diversidade linguística e de pluralidade cultural em uma perspectiva lexical.
Expressões impessoais no discurso acadêmico brasileiro
Authors: Vieira Marcia Dos Santos Machado
Published: December 2017

Este artigo enfoca a comparabilidade de microconstruções com ter-se e haver relacionadas ao domínio funcional da impessoalização discursivo-pragmática, da construção gramatical de impessoalização. Esse estudo descreve, com base no Sociofuncionalismo, o aumento da frequência da recorrência a instâncias da microconstrução com ter-se num intervalo de tempo e os condicionamentos da variação (estável) de usos desse padrão gramatical com os da microconstrução com o verbo haver: a área acadêmica e a semântica de SN, por exemplo. A mudança que se nota na microconstrução ter-se SN decorre da cristalização sintática de seus componentes e da associação de sua extensão de sentido indefinido com uma extensão de sentido impessoal (existencial ou apresentacional), o que propicia sua equivalência funcional com construções com haver e sua atuação como estratégia discursivo-pragmática que possibilita tornar opaca a presença do enunciador. Os resultados advêm de análise estatística e qualitativa de usos detectados em textos acadêmicos de áreas distintas do conhecimento. Tencionase, em última instância, contribuir também para a discussão teórica sobre o lugar da variação em estudos sob a ótica da  ramática das Construções, que, até então, se tem voltado para o fenômeno da mudança linguística.
