Remittances, Spending, and Political Instability in Ukraine
Authors: Kuntsevych Iuliia 
Published: April 2016

Abstract
This paper offers an analysis of remitt ances sent by Ukrainian emigrants to their country of origin. It explores how far the expenditure on remitt ances by individual Ukrainians and the total amount of all remitt ances received from abroad has been dependent on the political situation of the Orange Revolution and Presidential Elections in Ukraine in 2004. The author then investigated what effect the political instability in Ukraine had on how households there used such remittances. She used the results of a nationally representative survey of households in Ukraine to compare individual decisions to invest money received from remittances, and how those decisions depended on individual political views and future expectations. Changes in emigrants’ expectations might increase emigrants’ willingness to offer financial support to relatives remaining in Ukraine.
A Two Parameter Discrete Lindley Distribution
Authors: Hussain Tassaddaq , Aslam Muhammad , Ahmad Munir 
Published: April 2016

<p>In this article we have proposed and discussed a two parameter discrete Lindley distribution. The derivation of this new model is based on a two step methodology i.e. mixing then discretizing, and can be viewed as a new generalization of geometric distribution. The proposed model has proved itself as the least loss of information model when applied to a number of data sets (in an over and under dispersed structure). The competing models such as Poisson, Negative binomial, Generalized Poisson and discrete gamma distributions are the well known standard discrete distributions. Its Lifetime classification, kurtosis, skewness, ascending and descending factorial moments as well as its recurrence relations, negative moments, parameters estimation via maximum likelihood method, characterization and discretized bi-variate case are presented.</p>

Published: April 2016

<p>Conventional measures of location are commonly used to develop ratio estimators. However, in this article, we attempt to use some non-conventional location measures. We have incorporated tri-mean, Hodges-Lehmann, and mid-range of the auxiliary variable for this purpose. To enhance the efficiency of the proposed mean ratio estimators, population correlation coefficient, coefficient of variation and the linear combinations of auxiliary variable have also been exploited. The properties associated with the proposed estimators are evaluated through bias and mean square errors. We also provide an empirical study for illustration and verification.</p>

Se trata de un estudio transversal de alcance correlacional que contó con una muestra de 101 cuidadores, evaluados por medio de los instrumentos Zarit, MOS, IDER, Coping, la Escala de Resiliencia de Wagnild y Young. Se identificaron correlaciones positivas estadísticamente significativas entre apoyo social y solución de problemas como estrategia de afrontamiento y resiliencia, y correlaciones negativas con depresión, evidenciando en estos resultados los factores protectores y de riesgo que pueden aportar a la creación de futuros programas de intervención.</p>
El Lado Socialmente Deseable de las Respuestas a Medidas de Burnout y Engagement: un Estudio Preliminar
Authors: Fernández-Arata Manuel , Merino-Soto César 
Published: April 2016

<p>El presente estudio reporta la asociación divergente entre la deseabilidad social y las respuestas al MBI-GS y UWES, dos<br />instrumentos que miden constructos considerados opuestos: <em>burnout</em> y <em>engagement</em>. Esta relación ha sido muy pocas veces explorada, y menos aun en sujetos hispanos. Los participantes fueron trabajadores de tiendas comerciales en la zona central de Lima Metropolitana. Se halló que la deseabilidad social comparte varianza con los puntajes de agotamiento emocional e indiferencia, pero esta relación estuvo influenciada por el instrumento de medición de la deseabilidad social. Las correlaciones parciales entre los puntajes del MBI no fueron prácticamente diferentes de sus correlaciones de orden cero. El UWES no covarió con deseabilidad social. Se concluye que la deseabilidad social tiene poca influencia sobre los puntajes orientados hacia el burnout en el MBI.</p>
Discurso narrativo e presente histórico em Paul Ricoeur
Authors: Leal Ivanhoé Albuquerque 
Published: April 2016

Analisamos uma das teses da teoria narrativa de Paul Ricoeur que concede ao discurso histórico a habilidade de configurar a experiência temporal humana, sempre exposta à trama de perspectivas cruzadas entre a expectativa do futuro, a recepção do passado e a vivência do presente. Face à multiplicidade do tempo, os lineamentos argumentativos ricoeurianos indicam o ato narrativo como a condição tanto de pensar a efetividade das ações humanas e sua reconstrução histórica quanto de forjar uma unidade plural própria a uma consciência hermenêutica
Humanidade e dignidade em Kant
Authors: Nodari Paulo César 
Published: April 2016

A ciência e a tecnologia ocupam um lugar fundamental e insubstituível na construção da realidade sociocultural atual. Estão ligadas ao destino da vida humana, sendo que o ser do homem está marcado cada vez mais pela ciência e a depender dela em sua efetivação. Porém, do expressivo avanço científico tecnológico advém um dilema que penetra o âmago da realidade sociocultural humana. O homem contemporâneo, por um lado, sente-se orgulhoso de ter superado a pura facticidade existencial de uma vida simplesmente inserida em crenças tradicionais, assumindo, por sua vez, a consciência de seu processo de autoconstrução e uma vida eminentemente racionalizada, mas, por outro, ele não consegue superar e ultrapassar a vigência histórica da normatividade da comunidade humana histórica na qual ele está inserido. Contudo, percebendo-se que o progresso científicotecnológico avança rapidamente, exigindo, pois, um novo espectro do raciocínio ético da ação, dimensão esta desconhecida a todas as formas precedentes de ação e reflexão, constata-se certo descompasso entre os avanços da ciência e da tecnologia com o alcance da reflexão e da práxis do agir ético, especialmente, depois que a ciência e a técnica ampliaram a margem de liberdade e autonomia a ponto de ser possível afirmar, depois de um desencantamento da natureza externa, agora, uma espécie de um novo encantamento com a natureza interna. À luz dessa nova conjuntura sociocultural, tem-se o propósito de remontar à Fundamentação da metafísica dos costumes de Kant na segunda formulação do imperativo categórico, humanidade como fim, a fim de investigar se a mesma, por um lado, pode ser aproximada à compreensão do fim último e do fim final no processo de moralização na Crítica do juízo, e, por outro lado, se tal formulação pode ser ancoradouro razoável à discussão ética contemporânea de espectro em nentemente científico.
Rendimiento académico y autopercepción de inteligencias múltiples e inteligencia emocional en universitarios de primera generación
Authors: Barraza López René , González A. Mauricio 
Published: April 2016

El objetivo del presente artículo fue determinar la relación entre la autopercepción de inteligencias múltiples e inteligencia emocional y el rendimiento académico alcanzado por 252 estudiantes de nivel universitario de diversas carreras de la Universidad Santo Tomás-La Serena, tras el primer año de educación universitaria. Los antecedentes teóricos y empíricos establecen que el rendimiento académico se asociaría a variables novedosas como: ser primer miembro familiar en iniciar estudios universitarios y a la autopercepción de habilidad; no obstante, la evidencia disponible respecto de esta relación es aún escasa y contradictoria, más todavía si se considera que el grupo evaluado proviene mayoritariamente de familias con padres sin formación universitaria. Desde un enfoque cuantitativo se aplicó la escala TMMS-24 para la evaluación de la autopercepción de inteligencia emocional y la escala MIDAS-teens para la evaluación de la autopercepción de inteligencias múltiples. Los resultados revelan correlaciones débiles entre rendimiento académico y la autopercepción de las inteligencias: lingüística, lógico-matemática, además de una correlación inversa con la autopercepción de la rama atención de inteligencia emocional; de este modo, no evidencia correlación con la otras dimensiones de la inteligencia emocional y de las inteligencias múltiples. A partir del análisis de regresión múltiple se establece que no es posible explicar la varianza del rendimiento académico desde la autopercepción de las inteligencias mencionadas. Queda abierta la interrogante en cuanto al real efecto de la autovaloración de las propias capacidades en el rendimiento académico, como también el efecto de las formas de evaluación utilizadas en diversas áreas disciplinares respecto de estos resultados.

Published: April 2016

Abstract

Background.
We explored biologics receipt in metastatic colon cancer.

Methods.
We used Surveillance, Epidemiology, and End Results-Medicare data of 4,545 elderly patients diagnosed with incident metastatic colon cancer from 2003 to 2009, treated with chemotherapy and/or biologics, and followed up through 2010.

Results.
A total of 2,504 (55%) patients received a biologics-containing regimen. Treatment with biologics fluctuated between 46% and 63% of first-line regimens and 67% and 73% of second-line regimens. Bevacizumab accounted for 95% of first-line and 68% of second-line biologics use. Cetuximab accounted for 33% of second-line and 48% of third-line use. Panitumumab accounted for 5% of second-line and 27% of third-line use. The adjusted odds of biologics receipt decreased rapidly with age, resulting in a threefold difference between the youngest and the oldest study participants in the sample (odds ratio [OR] 0.35, p &lt; .01). African Americans (OR 0.77, p = .03) and patients with Charlson Comorbidity Index of 1 (OR 0.83, p = .02) or &gt;1 (OR 0.75, p &lt; .01) were considerably less likely to receive biologics therapy. Medicare state buy-in was associated with 2% lower odds of receiving biologics (OR 0.98, p = .04).

Conclusion.
After controlling for sociodemographic and clinical differences, age, race, comorbidities, and low income had a statistically significantly negative effect on the likelihood of receiving biologics among treated patients. Use of biologics varied over time, across the treatment continuum, and by chemotherapy regimen. Bevacizumab was most frequently used in both first- and second-line treatment. Cetuximab was the second most prescribed biologic. Panitumumab use was mostly limited to third-line treatment.
Delivering work-ready business graduates - keeping our promises and evaluating our performance
Authors: Jackson Denise , Sibson Ruth , Riebe Linda 
Published: April 2016

Business schools globally are responding to calls for graduate work-readiness primarily through the development of employability skills, encompassing career management skills, and work integrated-learning (WIL). There has been considerable attention to clarifying precisely which skills should be developed, and how, but far less on evaluating employability skill provision and its impact on graduate work-readiness. This is increasingly important as industry worldwide continues to lament graduate inadequacies in certain employability skills and the extent to which they are job-ready.
This paper outlines a systematic approach for evaluating employability skill outcomes and the effectiveness of learning programs in developing these skills. The approach was developed in a learning program dedicated to developing employability skills in business undergraduates in an Australian university. It may assist other universities in communicating, assessing, mapping and reporting their employability skills outcomes; an integral component of all business undergraduate programs, and now a requirement of all Australian higher education providers (TEQSA, 2011). The approach provides a means of evaluating program effectiveness in skill provision, enabling a more informed review of curricula content, assessment and pedagogical techniques to achieve better alignment with industry requirements.
GOVERNANÇA NOS MERCADOS EMERGENTES
Authors: Lameira Valdir de Jesus 
Published: April 2016

Neste artigo procura-se evidenciar o relacionamento entre governança e diversas variáveis econômicas ou financeiras dos mercados emergentes. Com esse objetivo estabeleceu-se um referencial teórico contendo os conceitos fundamentais ligados ao nível de governança dos países que sugere influência no desempenho dos países. A amostra com que se trabalhou foi composta de um grupo de países emergentes, tendo sido considerado como critério para sua composição a existência de um nível de renda per capita por habitante por ano que se situasse entre U$ 500 e U$ 20.000. Em seguida procurou-se selecionar alguns indicadores médios de desempenho econômico e financeiro desses países no período entre 2000 e 2002. Todos os dados econômicos e financeiros dos países foram obtidos junto ao site do Banco Mundial. Posteriormente utilizou-se o método de regressões lineares múltiplas de modo a investigar possíveis relações estatísticas entre as variáveis. Os resultados apontam para a existência de uma relação positiva entre governança e renda per capita e negativa entre governança e crescimento econômico entre outras relações relevantes.
ANÁLISE DO PROCESSO DECISÓRIO NO AGRONEGÓCIO: ABORDAGEM NA CADEIA DE VALOR DA SOJA
Authors: Oliveira Deyvison de Lima , Pereira Sidinei Aparecido 
Published: April 2016

A análise do processo decisório no agronegócio, com abordagem na cadeia de valor, insere-se no campo dos estudos ainda incipientes. O trabalho objetiva identificar fontes de informações da cadeia de valor utilizadas na tomada de decisão em organizações produtoras de soja. O processo decisório com foco na cadeia de valor considera três contextos: fornecedores, organização e clientes. As tomadas de decisões, objetos da pesquisa, estão reunidas em três blocos: decisões de investimentos, financiamentos e continuidade do negócio. Observou-se que no interior da cadeia de valor as informações da Gestão Estratégica de Custos (análise Custo-Volume-Lucro – CVL) são utilizadas em menor escala, se comparadas com as fontes de informações dos elos da cadeia, que se situam além da porteira do empreendimento. O procedimento metodológico utilizado é o estudo de campo, com aplicação de formulário para a coleta de informações junto a gestores da produção de soja no município de Vilhena-RO.
A INFLUÊNCIA DAS REDES SOCIAIS DE CATADORES NA CADEIA PRODUTIVA DA RECICLAGEM
Authors: Farias Filho Milton Cordeiro , Pires José Otavio Magno 
Published: April 2016

O artigo apresenta os resultados de uma pesquisa com oito grupos de catadores de materiais recicláveis em seis municípios do estado do Pará. O objetivo foi examinar as influências de suas redes pessoais na capacidade das organizações e na apropriação desses agentes na cadeia da reciclagem. A análise de redes sociais foi considerada a metodologia mais adequada para identificar os relacionamentos entre os catadores e seus efeitos na organização e na cadeia da reciclagem. Os dados foram levantados via questionário (gerador de nomes) específico para análise de redes sociais e organizados no software Ucinet 6.4. As análises foram feitas a partir das medidas de densidade, complementadas com informações de entrevistas e observações livres em lixões e aterros sanitários. A base analítica foi a tese da “força dos laços fracos” e a concepção de “cadeias produtivas” e “integração vertical”. Os resultados revelam que não há diferença entre redes de catadores organizados e não organizados e que por serem grupos fechados encontram dificuldades no acesso aos recursos que estão fora de suas redes. Esta característica tem reflexos na cadeia produtiva, dentre as quais estão a fragilidade das cooperativas, o baixo rendimento obtido no trabalho e a redução da capacidade produtiva dos catadores. A principal conclusão da pesquisa é a de que o baixo nível de densidade das relações nas redes dos grupos estudados limita as ações das organizações de catadores, representando obstáculo para elevar os resultados desses profissionais na cadeia da reciclagem.
Models of Thermal EOR in Fractured Reservoirs
Authors: Ziegler V. M. 
Published: April 2016

Abstract
Models for hot-water or steam injection into a fractured shale or diatomite reservoir are developed from existing analytic models of energy transport and counter-current imbibition.
Radial convective heat flow through a horizontal fracture system is modeled with conductive heat flow into the low permeability matrix. The flow geometry approximates hot fluid injection into a five-spot pattern. Recovery mechanisms accounted for in the models include capillary imbibition and thermal expansion. Temperature dependence of viscosity and interfacial tension are included in the imbibition estimate. Laboratory data is needed to quantify the magnitude of the imbibition mechanism, which is usually the primary contributor to oil recovery. Data representative of either the Belridge Diatomite or the Antelope Shale, two giant fractured oil reservoirs, are used for the model forecasts.
The steamflood model has been partially validated against a large-scale project in the Belridge Diatomite. Using public-domain information, a reasonable match was obtained between the model and field project over a four-year injection period. Comparison to conventional thermal simulation was also performed and indicated reasonable agreement with the steamflood analytical model.
The models have been used to determine the key factors determining the success of thermal recovery in fractured, low-permeability reservoirs. Steam injection is shown to be superior to hot water injection in heating the matrix. Key factors enhancing recovery include: reduced fracture spacing, increased matrix permeability and increased injection temperature. Model results indicate that steamflood recoveries in excess of 40% of the original oil-in-place (OOIP) may be achieved by injection in both diatomite and shales containing light oils. Application to diatomites containing heavy oil also shows good performance. Successful application in diatomite reservoirs is forecast to be possible in the current low oil price environment. Economic application in fractured shales, would require a higher oil price because of the higher well costs and lower oil content relative to diatomite projects.
Because of the significant volumes of remaining oil in place in both the diatomite and shale reservoirs, application of thermal enhanced oil recovery (EOR) to these resources represents the logical next step in steamflood development.
Detecting Opal-CT Formation Resulting From Thermal Recovery Methods in Diatomites

Abstract
Evaluation of the effects of thermal recovery methods upon diatomaceous reservoirs with their inherent high porosity and low permeability is problematic in that diatoms, a main component of their namesake rock, are composed of amorphous, hydrous biogenic silica (Opal-A) and can alter when heated. The opal-A to opal-CT transformation, is readily apparent using imaging methods, X-ray diffraction (XRD), and petrophysical measurements when the rock has been fully converted. In laboratory experiments with partial transformation, these changes, if any, are subtle and easily missed due to the minute amount of alteration products and the substantial amount of natural variability within the rocks. For example, XRD measurements may show an increase of 1 wt % in opal-CT after an experiment. It is not apparent whether additional opal-CT either formed as a result of the experiment or is a relative enrichment caused by the dissolution of more susceptible minerals such as opal-A and pyrite.
A new method based on nitrogen sorption was developed to detect silica-phase alteration in diatomaceous samples. We observed that nanometer-scale pore-size distributions as measured via nitrogen sorption and processed using the classic BJH method differ for opal-A and opal-CT reservoir samples. Opal-A samples have less nanometer-scale pore volume (~0.1 cc/g), smaller nanoscale pore sizes (~3.8 nm), and distinct pore-size distributions compared to samples containing opal-CT (e.g., 0.3 cc/g and 6.6 nm). This method detects subtle amounts of opal-CT in that samples containing only 3 wt % (XRD) exhibit a distinct opal-CT peak at 7.8 nm in one example. These nanometer-scale pore-size changes occur whether micrometer-scale pores either increase in size (dissolution) or decrease in size (alteration).
This method was applied to reservoir and quarry diatomites before and after laboratory experiments conducted at ambient to 230 °C temperatures, pH values of 6 to 10, durations of 10 hours to two years, different fluids, various pressures, and a gamut of flow conditions including spontaneous imbibition, forced imbibition, and static. Supporting data such as water chemistry and XRD data were also measured. Comparison of before and after BJH pore-size distributions reveals a reduction in peak size when dissolution occurs and a shift to larger nanometer-scale pore sizes when alteration (converting to opal-CT) occurs. Many samples exhibit both characteristics. The inlet side of the cores exhibit more dissolution and alteration than the outlet side of the same core. Other factors could also contribute to these changes in the nanometer-scale pore structure such as fines mobilization and compaction.
