Attention deficit hyperactivity disorder: concomitant diseases with an emphasis on epilepsy
Authors: Pylaeva O. A. , Shatenshtein A. A. , Mukhin K. Yu.
Published: December 2018

Attention deficit hyperactivity disorder (ADHD) is the most common cause of behavioral disorders and learning difficulties in preschool and school-age children. Patients with ADHD are often diagnosed with concomitant diseases, which creates additional diagnostic and therapeutic challenges and leads to a more significant reduction in the quality of life. ADHD is often associated with epilepsy: ADHD manifestations are more common in individuals with epilepsy, and vice versa, patients with ADHD are more likely to have epilepsy. The estimated prevalence of ADHD in children is 7–9 %, whereas in children with epilepsy, it reaches 20–50 %. Epilepsy is also one of the most common diseases in children (affecting approximately 1 % of the pediatric population), which is often aggravated by concomitant diseases, including cognitive, behavioral and emotional disorders. Various factors, such as characteristics of epileptic process and lesions in particular portions of the brain, can underlie the development of ADHD in epilepsy. Epileptiform activity and adverse effects of antiepileptic drugs can also play an important etiological role. Some antiepileptic drugs (such as barbiturates) may cause symptoms similar to those in ADHD (in this case, inattentiveness and hyperactivity shall be considered as adverse events that can be reduced or eliminated after cessation of the drug) or exacerbate ADHD symptoms in patients with these disorders. Therefore, the drugs with no negative impact on concomitant diseases or with a positive therapeutic effect for both diseases are preferable in these cases.

High prevalence of the ADHD/epilepsy combination leads to a greater reduction in the quality of life, suggesting high relevance of this problem and requiring a revision of therapeutic approaches.
Benign epileptiform discharges of childhood and associated conditions
Authors: Mukhin K. Yu.
Published: December 2018

This article provides a detailed description of benign epileptiform discharges of childhood (BEDC) as one of electroencephalography patterns in children. We emphasize that BEDC are not specific for both idiopathic (genetic) focal epilepsy and epilepsy in general. BEDC can be observed in a number of various disorders and also in neurologically healthy children. We developed a detailed classification of BEDC-associated states that are divided into 3 groups: neurologically healthy children, children with various forms of epilepsy, and patients with various neurological disorders without epilepsy. We found that there are 2 main factors responsible for BEDC in electroencephalogram: genetic predisposition and white matter lesions, usually occurring during the antenatal or perinatal period. BEDC should be considered rather a manifestation of congenital abnormalities in brain maturation than a marker of epilepsy. We also discuss the need for therapy in patients with BEDC-associated states.

Öğrencilerin nicel
muhakeme yoluyla doğrusal fonksiyondaki temel çoklukları düşünmeleri, yeni
çokluklar oluşturmaları ve farklı gösterimler arasında ilişkilendirmeler
yapmaları kavramsal öğrenme için önemlidir. Bu çalışmada doğrusal fonksiyonun öğrenilmesine
yönelik tasarlanan modelleme etkinliği üzerinde çalışan öğrencilerin nicel
muhakemelerini incelemek amaçlanmıştır. Öğretim deneyine dayalı
gerçekleştirilen çalışmanın katılımcılarını bir fen lisesindeki üçü kız, yedisi
erkek on tane 10.sınıf öğrencisi oluşturmaktadır. Öğrenciler yazılı olarak
verilen etkinlik üzerinde kendi belirledikleri ikişer kişilik gruplar halinde
çalışmışlardır. Grupların çözüm kağıtları ve etkinlik çalışmaları boyunca
alınan video kamera kayıtlarının transkriptleri araştırmanın verilerini oluşturmuştur.
Toplanan veriler öğrencilerin nicel muhakemeleri doğrultusunda devam eden
analizler ve geriye dönük analizler olarak iki aşamada analiz edilmiştir. Analizler,
öğrencilerin deneyimledikleri ya da anlam yükleyebildikleri bir durum üzerinde
çalışırlarken zihinsel olarak daha aktif eylemler sergilediklerini göstermiştir.
Etkinliğin yansıtıcı soyutlamayı destekleyecek nicel muhakemeleri göz önüne
alarak tasarlanmasının öğrencilerin çoklukları oluşturmalarını desteklemede
önemli bir etken olduğu söylenebilir. Bu bağlamda modelleme etkinliklerinden
kavram öğretimi süreçlerinde yararlanılması önerilmektedir.

Authors: CANBOLAT Önder , AKBAY Kadir Cem , KAMALAK Adem
Published: December 2018

Bu araştırma, yem bezelyesi (Pisum Sativum L.) silajına suda çözünür karbonhidrat (ŞÇK)  kaynağı olarak melas ilavesinin silo fermantasyonu, mikrobiyolojisi, in vitro gaz üretimi ve nispi yem değerleri (NYD) üzerine etkilerini saptamak için düzenlenmiştir. Bu amaçla yem bezelyesi bakla doldurma döneminde hasat edilmiştir. Hasat sonrası yaklaşık 1.5-2.0 cm boyutunda parçalanan taze materyale 0 (kontrol), 15, 30, 45 ve 60 g/kg taze materyal (TM) düzeyinde melas katılmıştır. Melas ilavesi yem bezelyesi silajlarının ham besin maddeleri bileşimini önemli derecede etkilemiştir (P<0.01). Melas dozuna bağlı olarak silajların ham protein (HP), ham yağ (HY), nötr deterjan lif (NDF), asit deterjan lif (ADF) ve asit deterjan lignin (ADL) içeriği azalmış, kuru madde (KM), ham kül (HK) ve suda çözünebilir karbonhidrat (SÇK) içeriği artmıştır (P<0.01). Melas ilavesi yem bezelyesi silajlarının pH’sını, asetik asit, bütirik asit ve amonyak azotu (NH3-N) içeriklerini düşürürken, laktik asit ve propiyonik asit içeriklerini artırmıştır (P<0.01). Aynı şekilde melas ilavesi  yem bezelyesi silajlarının  in vitro gaz üretimi, organik madde sindirim derecesini (OMSD) ve metabolik enerji (ME) içeriklerini de artırmıştır (P<0.01). Melas ilavesi ayrıca yem bezelyesi silajlarının nispi yem değeri (NYD) ve kuru madde tüketimi (KMT)’ni olumlu yönde etkilemiştir (P<0.01). Araştırma sonucunda, melasın SÇK düzeyi düşük olan yem bezelyesi silajlarında kullanılması, silajların yem değerini ve fermantasyon özelliklerini iyileştirmiştir.
Saberes ocultos no Brasil Império: a arte da cura pelo magnetismo animal e a busca pela legitimidade * Hidden knowledge in Brazil Empire: the art of cure for animal magnetism and the search for legitimacy
Authors: Lacerda Danielle Christine Othon
Published: December 2018

Os princípios e a prática do magnetismo animal consolidaram-se na França poucos anos antes da Revolução Francesa acontecer. Em meio a polêmicas e um crescente número de adeptos, o magnetismo animal ultrapassa as barreiras do tempo e as fronteiras espaciais, chegando ao Brasil nas primeiras décadas do século XIX por meio do imigrante francês Leopold Gamard. O objetivo deste trabalho foi compreender as tentativas de Gamard de legitimar o magnetismo animal como prática curativa, perante as instituições científicas médicas e a opinião pública na Corte imperial. Para tanto, examinamos periódicos científicos e jornais populares na tentativa de juntar fragmentos para recompor a intrigante trajetória de Leopold Gamard e que ajudaram a tecer a trama das relações sociais na construção de representações e apropriações da prática do magnetismo animal, como uma alternativa para cura de moléstias.*The principles and practice of animal magnetism were consolidated in France a few years before the French Revolution took place. Amid controversy and a growing number of adepts, animal magnetism surpasses the barriers of time and space frontiers, arriving in Brazil in the first decades of the nineteenth century through the French immigrant Leopold Gamard. The purpose of this work was to understand Gamard's attempts to legitimize animal magnetism as a curative practice before medical scientific institutions and public opinion in the imperial court. In order to do so, we examined popular scientific journals and newspapers in an attempt to combine fragments to reconstruct Leopold Gamard's intriguing trajectory and helped to weave the fabric of social relations in the construction of representations and appropriations of the practice of animal magnetism as an alternative for healing diseases
A construção de uma literatura moderna nas obras de Charles Perrault em meio a querela dos Antigos e dos Modernos * The construction of a modern literature in Charles Perrault's works in the middle of the quarrel of the Ancients and the Moderns
Authors: Martins Juliana Timbó
Published: December 2018

Conhecida, já no século XVII, como querela dos Antigos e dos Modernos, a série de debates entre membros da Academia Francesa opôs, de um lado, aqueles que defendiam a exemplaridade da Antiguidade na produção artística e literária do período e, de outro, os partidários da legitimidade da criatividade dos artistas modernos. Entre os letrados que em pleno reinado de Luís XIV deram ensejo a essa disputa, Charles Perrault se destacou não apenas como porta-voz dos autointitulados Modernos, mas também como o estopim e catalisador do debate. Nesse sentido, este trabalho tem como objetivo apresentar as ideias e argumentos do poeta francês durante a querela a fim de evidenciar em suas obras tanto a defesa de uma literatura moderna, entendida como arte que expressa a singularidade de seu tempo, quanto o exercício de suas premissas na escrita de Contos da Mamãe Gansa, obra de maior sucesso do autor e da literatura francesa.*Already known in the seventeenth century as the quarrel of the Ancients and the Moderns, the series of debates between members of the French Academy opposed, from one side, those who defended the exemplarity of antiquity in the artistic and literary production in that age and, on the other side, the legitimacy partisans of the modern artists’ creativity. Among the scholars who, during Louis XIV’s reign, created the occasion to such dispute, Charles Perrault stood out not only as an advocate to Moderns, but also as the trigger and the catalyst of the debate. In this regard, this paper aims to present the ideas and arguments of the French poet during the quarrel in order to highlight in his works both the defense of modern literature whereas art that expresses its time’s singularity, and the exercise of his premises in the writing of Tales of Mother Goose, the most successful work of the author and French literature.

Authors: Elíbio Jr Antônio Manoel , Nascimento Fernanda De Santos
Published: December 2018

Este artigo tem por o objetivo analisar a categoria “Questões Nacionais (ou não-militares)” na Revista A Defesa Nacional (ADN).  Chama a atenção ao investigarmos a ADN, que temas como o papel do Exército/ Militares e a política sejam tão frequentes quanto os assuntos relacionados à organização militar e às reformas militares. A recorrência destes assuntos demonstrada na formação do corpus deste trabalho tornou-o relevante para a análise sobre A Defesa Nacional nas edições aqui levantadas publicadas entre os anos de 1931 a 1937. Portanto, procuraremos problematizar o papel dos militares na República e a “modernização do Exército” que são discutidos pelos redatores da ADN, sobretudo pela oficialidade do Exército Brasileiro.*This paper aims to analyze the category "National issues (or non-military)" in the A Defesa Nacional Journal. As we investigate the journal, we noticed that themes such as the role of the Army / Military and politics are as frequent as the issues related to the military organization and military reforms. The recurrence of these subjects displayed in the formation of the corpus of this work made it relevant to the analysis of Defesa Nacional journal on issues raised here published between 1931 and 1937. We will, therefore, seek to problematize the role of the military in the Republic and the "modernization of the Army" that are discussed by the editors of the Defesa Nacional Journal, especially by officers of the Brazilian army.
Ética animal en Coloquio de los Perros
Authors: Marrero-Henríquez José Manuel
Published: December 2018

La sensibilidad contemporánea contra el maltrato animal conforma un horizonte de expectativas en el que descuellan detalles de Coloquio de los perros capaces de transformar el relato de Berganza en un texto en defensa de los derechos de los animales, tan dulce y útil como antaño, si bien ahora la poética horaciana acordada con la ética animalista y con la sensibilidad ecologista de los tiempos que corren. Nada es evidente, parece decir Cervantes, ni la inteligencia y la racionalidad del animal humano, ni la inconsciencia y mecanicismo autómata del animal no humano. En el contexto del Antropoceno, Coloquio de los perros se revela como una lectura crítica de los fundamentos de la excepcionalidad humana y como una reflexión descarnada sobre las relaciones de poder entre seres humanos y entre éstos y la naturaleza y los animales que la habitan.
El álbum sin palabras: la construcción de una comunidad lectora en la biblioteca pública
Authors: Colón María Jesús , Tabernero-Sala Rosa
Published: December 2018

Este artículo presenta un estudio de caso cualitativo de modalidad etnográfica. El estudio se efectuó en una biblioteca pública del ámbito rural aragonés. Durante un curso escolar, 41 niños de tres a once años participaron en un taller de lectura en el que se utilizaron álbumes sin palabras. Esta investigación responde a dos preguntas: qué estrategias utilizaron los lectores infantiles en la recepción de álbumes sin palabras y qué significados otorgaron los actores del contexto a la experiencia socioeducativa. Para el tratamiento de los datos se utilizó el método comparativo constante con el apoyo del software NVivo. Se analizaron las respuestas lectoras generadas en la recepción de La ola y Sombras de Suzy Lee, las entrevistas realizadas a los participantes y el diario de campo de la investigadora. Las respuestas lectoras indican que los álbumes sin palabras propician el desarrollo de estrategias de lectura a través de la interacción oral y la construcción conjunta de sentido. Los datos obtenidos a lo largo del estudio muestran además que la lectura colectiva continuada generó una comunidad lectora y que los hábitos de lectura y la función social de la biblioteca se vieron reforzados.

Published: December 2018

Cardiovascular (CVS) morbidity and mortality in the peritoneal dialysis patients (PD) is 10-30-fold higher than in the general population. A relatively low level of adiponectin and a higher level of leptin are important predictors of vascular complications as well as CVS events in PD patients. The asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, is an important risk factor of CVS morbidity and mortality. It is very important to establish all CVS risk factors in the PD patients to prevent CVS morbidity and mortality in this population. The aim of the study was to determine the plasma concentration of ADMA and adipokines in relation to the protein-energy wasting (PEW) in PD patients.The study was performed in 30 PD patients and in the control group which consisted of 23 healthy volunteers. Plasma levels of hsC-reactive protein, TNF, IL-6, leptin, adiponectin, oxyLDL and ADMA were measured by ELISA method in both groups. The nutritional status was determined by measuring the albumin, body mass index (BMI), the percentage of body fat (%F), lean body mass (LBM) and Subjective Global Assessment Score (SGA). The adequacy of dialysis was estimated by weekly Kt/V. In all PD patients, significantly higher levels of ADMA, leptin, oxyLDL, hsCRP and TNF in comparison to controls were observed. In contrast to well-nourished subjects, patients with PEW, in addition to increased hsCRP, showed significantly higher ADMA. PEW was associated with high levels of ADMA and hsCRP and this could probably be responsible for increased CVS risk in PD patients.

Authors: Araujo Carolina Dutra de , Cândido Débora Regina Campos , Krott Max
Published: December 2018

O turismo de base comunitária pode ser uma alternativa para o desenvolvimento do turismo na medida em que este promove o empoderamento das comunidades locais nos processos de tomada de decisão. Entretanto, os diferentes interesses dos atores envolvidos apresentam-se como entraves a essa alternativa. O objetivo deste estudo é identificar os elementos de poder dos atores mais poderosos que exercem influência no Parque Nacional Marinho de Fernando de Noronha, a fim de analisar se há condições de desenvolvimento de turismo de base comunitária na ilha, de acordo com o apoio desses atores. Para tanto, foi analisada a distribuição de poder entre os atores levando-se em consideração coerção, incentivos e desincentivos, e informação dominante por meio de entrevistas com oito atores considerados mais poderosos, com interesse em turismo no local. Acredita-se que quando os interesses dos atores mais poderosos são contemplados, o planejamento do turismo pode ser mais efetivo. Nesse contexto, o turismo de base comunitária emerge como uma das alternativas possíveis para um desenvolvimento turístico mais justo para as comunidades locais. Os resultados indicam que há algum apoio ao turismo de base comunitária por parte dos entrevistados, entretanto, o cenário observado é de excessiva valorização do conhecimento técnico, notadamente por ser uma área protegida, o que afasta o residente dos processos de tomada de decisão.
Turismo gastronômico e desenvolvimento regional: um estudo a partir do caso do queijo minas artesanal do Serro
Authors: Medeiros Mirna De Lima , Cunha Júlio Araujo Carneiro da , Passador João Luiz
Published: December 2018

Práticas alimentares tradicionais incorporadas ao turismo local podem tornar-se mais do que manifestações culturais e identitárias, elementos estratégicos para uma “marca” local. Assim, objetivou-se analisar o turismo gastronômico relacionado ao queijo minas artesanal do Serro. Especificamente buscou-se verificar a percepção e atitude do turista com relação ao QMA do Serro e atividades relacionadas ao produto; analisar a opinião de stakeholders; e tecer apontamentos com relação ao aproveitamento turístico do QMA do Serro e o desenvolvimento econômico e cultural. A teoria de sustentação discutiu a influência do turismo gastronômico no desenvolvimento regional (econômico e cultural). Para tal fim, optou-se por um estudo de caso de design rígido, planejado e com proposições bem definidas. A coleta de dados contemplou um questionário aos turistas que visitaram a região queijeira (103 respostas válidas); entrevistas com pessoas envolvidas com a produção ou comercialização do QMA do Serro (15 sujeitos) e análise documental. A análise se deu por análise de conteúdo e estatística descritiva. O potencial turístico do QMA do Serro é confirmado, contudo, há subaproveitamento de recursos que parece implicar em baixo incremento econômico e de trocas de conhecimentos limitadas, que poderiam melhor ocorrer em redes.
Effect of biodegradation processes on the composition and structure of asphaltenes in West Siberian oils
Authors: Borisova Lyubov S. , Fursenko Elena A.
Published: December 2018

NMR spectroscopy in combination with elemental analysis was used to study asphaltenes in biodegraded oils from Cenomanian pools of West Siberia. The sampling depths vary from 680 to 1800 m, formation temperatures – from 40°C to 70°C. For comparison, we used the data on asphaltenes in non-biodegraded oils of different genotypes. Given that biodegraded oils are very heavy (density: 910-950 kg/m3), they are characterized by high boiling point temperatures (145-270°C). Due to the loss of hydrocarbon components, they have higher resin and asphaltene content (9-20%) compared to non-degraded samples. Elemental analysis of asphaltenes in biodegraded and unaltered oils of different genotypes revealed an increasing trend for oxygen content in the asphaltenes from biodegraded samples, which may result from the oxidation of structural blocks of asphaltenes during microbial oxidation. It was shown that the aromaticity of the moderately biodegraded terrestrial-aquatic Novoaganskaya samples tends to increase with a decrease in asphaltene saturation, suggesting that the redistribution of structural groups of asphaltenes may be caused by biodegradation processes. High saturation of asphaltenes in strongly biodegraded Gubkinskaya and Novoportovskaya oils, along with a high degree of substitution of aromatic compounds in asphaltenes in Gubkinkaya oils (terrestrial and aquatic-terrestrial genotype) can be attributed to the formation of asphaltenes during strong biodegradation of hydrocarbon components in these oils.

Authors: Garita César , Ortiz Giannina , Mora-Mora Juliana
Published: December 2018

Los puentes representan un componente fundamental de la infraestructura vial de cualquier país.  Daños y deficiencias en puentes pueden tener un impacto directo en la ejecución de actividades socio-económicas de la población en general. En Costa Rica, aún no se cuenta con un inventario completo de puentes en rutas nacionales por lo que resulta muy difícil conocer su condición real para poder diseñar y desarrollar un adecuado plan de mantenimiento e intervención a largo plazo, así como priorizar mejor la inversión de recursos estatales.  Para abordar este problema, el proyecto de investigación e-Bridge 3.0 planteado en el Instituto Tecnológico de Costa Rica, tiene como objetivo principal diseñar un prototipo de un sistema de monitoreo de puentes que permita integrar información de las estructuras existentes con el fin de apoyar la toma de decisiones por parte de diversos actores e instituciones en el área de gestión vial. Como base para el diseño del prototipo, se realizó una fase de análisis de requerimientos, incluyendo una revisión de trabajos relacionados y una comparación detallada de sistemas existentes que condujeron a la identificación de los actores, la información y los procesos principales que deben ser tomados en cuenta por un sistema de este tipo.  También se llevó a cabo un taller de consulta con un grupo de potenciales usuarios del sistema para validar los requerimientos.  Este artículo resume los resultados obtenidos del análisis de los requerimientos funcionales más importantes que debe considerar un sistema nacional de monitoreo de puentes.

Published: December 2018

La generación de residuos es causa inmediata de cualquier tipo de actividad humana, hoy en día se está ante una sociedad de consumo que genera gran cantidad y variedad de residuos sólidos biodegradables procedentes de una amplia gama de actividades. El presente estudio tuvo como objetivo la evaluación de tratamientos de estabilización de residuos sólidos biodegradables, provenientes del restaurante institucional del Tecnológico de Costa Rica, como alternativa de para gestionar y valorizar dichos residuos a través de la alimentación de cerdos de engorde. La estabilización se obtuvo a partir de una fermentación anaeróbica con microorganismos eficaces (EM), a partir de tres tratamientos que consideraron distintas proporciones de adición de EM, semolina, y melaza de caña en polvo, dispuestos en capas en microsilos para la fermentación. Se evaluaron cualitativamente parámetros físicos, y cuantitativamente parámetros nutricionales como fueron el porcentaje de proteína, fibra total, cenizas y extracto etéreo, así como humedad, pH, Energía Bruta, presencia de Salmonella y Coliformes Fecales. Como resultados se obtuvo un producto de tipo energético, estabilizado al ser llevado a un pH ácido y no se detectó presencia de patógenos. Finalmente, se realizó un análisis económico y ambiental del uso de los residuos estabilizados en un caso hipotético de producción porcina según parámetros nacionales, resultando en la posibilidad de obtener rentabilidad e inocuidad en los tratamientos, además de lograr evitar ciertos costos ambientales y una mejor gestión en general.
Inclusión de criterios ambientales en las compras públicas en Costa Rica: suministros de oficina
Authors: Gamboa-Castro Juan José , Salazar-Rojas Teresa
Published: December 2018

El sector público es el principal consumidor del país, por ende, tiene la capacidad de accionar los mercados hacia modelos de producción sostenibles. Costa Rica cuenta con iniciativas para promover las compras verdes y sustentables en sus instituciones estatales. Sin embargo, aún existe desconocimiento y falta de experiencia. Esta investigación propone la inclusión de criterios ambientales en los procesos de contratación administrativa, desarrollada en el Instituto Tecnológico de Costa Rica (ITCR) para la compra de suministros de oficina. Para esto, se definieron criterios ambientales con sus respectivas evidencias de verificación y se realizaron entrevistas a proveedores con el fin de determinar la factibilidad de cumplimiento. Los hallazgos encontrados reflejan la poca capacidad de los proveedores consultados para responder a los criterios ambientales, la importancia de realizar estudios de mercado para su adecuada clasificación en los carteles y la necesidad de formación ambiental de los entrevistados para obtener mejores rendimientos en las licitaciones.
Seeking Financial Advice and Other Desirable Financial Behaviors
Authors: Moreland Keith A.
Published: December 2018

Advice from financial counselors is one potential source for improving financial behaviors and well-being among clients and within their communities. This study examined whether obtaining financial advice is associated with other personal financial behaviors. Analysis of National Financial Capability Study data showed that obtaining advice is positively associated with financial behaviors while controlling for other relevant variables, including two measures of financial knowledge. The results also indicated greater benefits from obtaining advice for those with less financial knowledge. The findings suggest that efforts by financial counselors to provide financial advice to clients and others through service activities can improve financial decision-making in their communities including by those who can benefit the most.
User-Source Fit and Financial Information Source Selection of Millennials
Authors: Huang Emily J. , Lassu Reka A. , Chan Kenny K.
Published: December 2018

This study investigated Millennials’ source selection while searching for financial information to improve financial well-being. Results from an online survey of 488 business students at a Western U.S. university showed that Millennials used multiple sources when looking for financial information, but only sources whose perceived attributes fit the seekers’ preferences were considered; respondents favored family, employer/university, and government sources. Associations between personal characteristics (personal financial well-being, financial issue involvement, financial health self-efficacy, gender, and perception of source attributes) and financial information source selection were examined. Findings suggest financial practitioners, universities, and employers can improve their “fit” as financial information sources for Millennials by cocreating financial information with them, tailoring the communication channels, and enhancing the accessibility of information.
Perceptions of Retirement Adequacy: Evidence From South Africa
Authors: Reyers Michelle
Published: December 2018

Concerns regarding the adequacy of retirement savings have contributed to the move to encourage better savings behavior. One area of research focuses on understanding the profile of individuals who believe they are preparing adequately for retirement. The current study uses data from a national survey of South Africans to determine how confident workers are about their future retirement income adequacy, and whether behavioral characteristics play a role in their perception of retirement readiness. This study highlights the role that behavioral factors play in perceptions of retirement income adequacy in an African developing market context. In particular, financial risk tolerance, future time perspective, good financial behavior, and self-assessed financial knowledge are all found to be positively related to respondents’ retirement confidence.

Published: December 2018

This study investigates the relationship between financial self-efficacy (FSE) and saving behavior within a sample of 847 U.S. pre-retirees aged 50 to 70 from the Health and Retirement Study. In accordance with the social cognitive theory of self-regulation, results revealed that FSE is positively related to saving behavior after controlling for sociodemographic attributes, financial characteristics, and saving motives. Understanding how FSE contributes to saving behavior is critical as older workers attempt to bridge the retirement saving gap. Financial counselors and planners can help this population save by cultivating and supporting clients’ FSE throughout the financial planning and counseling process.
Income Uncertainty and Household Stock Ownership During the Great Recession
Authors: Shin Su Hyun , Kim Kyoung Tae
Published: December 2018

Using the 2007–2009 Survey of Consumer Finances (SCF) panel dataset, this study investigated the relationship between subjective income risks and stock ownership of 2,386 households with a working head before and after the Great Recession. We used subjective income uncertainty as a proxy for subjective income risks. A two-stage least squares (2SLS) estimation with an instrumental variables (IV) approach was used to reduce potential selection bias. The results suggested that households that were more likely to face subjective income uncertainty were less likely to hold stock assets in their portfolios. We confirmed this negative relationship between subjective income risks and stock ownership using tests of robustness.
Perceived Income Changes, Saving Motives, and Household Savings
Authors: Shin Su Hyun , Kim Kyoung Tae
Published: December 2018

Using the 2007–2009 Survey of Consumer Finances panel dataset, we investigate whether and how changes in perceived income and saving motives are related to demand for household savings in the United States after the Great Recession. Households that perceive their current income as lower, relative to normal years are less likely to save than those who view that their income is the same as the reference point. This result holds only for those who experienced a significant negative income shock during the Great Recession. Among five major saving motives, saving for an emergency is an important factor in explaining the likelihood of saving. This study suggests that financial planners and educators should pay close attention to the role of households’ income perception and saving motives and should account for the resulting potential psychological biases in households’ saving decisions.
Behind the Numbers: Understanding the Survey of Consumer Finances

Published: December 2018

The Survey of Consumer Finances (SCF) is the most frequently used dataset for research in this journal, but many researchers and readers do not fully understand some of the dataset’s complex details. This article provides insight into important issues that researchers and readers need to understand to accurately conduct and interpret SCF-based research. The issues addressed include the primary economic unit versus the household, identifying the respondent versus the head, limitations of variables in the survey, imputation and implicates, shadow variables, the public dataset versus the full dataset, weighting of analyses, and the use of replicate weights.
Ruderal Plants in Urban and Sub-Urban Walls and Roofs
Authors: YALÇINALP Emrah , MERAL Alperen
Published: December 2018

Objective: Main purpose of this study is to identify the ruderal plant species which spontaneously grows on the wall and roof surfaces in urban and sub-urban areas due to their limited ecological needs and to contribute to the creating of the sustainable green areas in urban environments by understanding the parameters that ruderals depend on while they require little maintenance and irrigation support if not no.Material and Methods: The main material of this study is the ruderal plants which were collected from totally 60 walls and 36 roof surfaces within six districts of Trabzon city –Akçaabat, Arsin, Çaykara, Of, Ortahisar and Yomra in Turkey. From these 96 habitats, 1540 plants samples form the walls and 448 plant samples from the roofs were collected. All the plant samples collected from the research area were identified in the herbarium of the faculty of forestry in Karadeniz Technical University. Apart from this, parametres affecting coverage rate of common species on three different habitats were analysed.Results: It was found that 448 samples from the roof surfaces distributed into 61 species while 1540 samples from the walls distributed into 196 species. Plus, according to the analyses, 28species were found on all three different habitats. As a result of the observations, measurements and analyses, it is clear from the study that coverage rate of the plant species depends onanthropogenic interaction, daylight period and depth of the media but there is no relation with the number of the species on the surfaces.Conclusion: Ruderal plants are definitely important to study on, if the world wants the term sustainability to find its real meaning as they require nearly nothing to grow in hard conditions.In urban life, maintenance is getting more and more expensive for green areas in urban life and this makes it difficult for them to survive especially when cities have limited budget on this, which has often occurred all over the world recently. There is no doubt that ruderal plants offer a great opportunity for modern era urban areas with their limited needs to grow in hard conditions. Furthermore, when thinking about the fact a serious amount of the ruderal plants detected on all three basic habitats has a great landscape plant characteristics, the approaches to their usage in urban areas are really critical.
O gaúcho como herói da decadência em Os ratos, de Dyonélio Machado
Authors: Sebben Ismael , Ceccagno Douglas
Published: December 2018

O objetivo deste artigo é identificar e analisar, na obra Os ratos, de Dyonélio Machado, com foco em seu protagonista Naziazeno Barbosa, a condição humana do homem citadino perante a Porto Alegre do início do século XX, ressaltando as transformações do mito do gaúcho herói, bem como explicitar os comportamentos daquele que se entende ser um herói da decadência. Para tanto, abordar-se-ão, a partir de textos teóricos que discorrem sobre a Porto Alegre da época, seu espaço e suas vivências, o imaginário das cidades, a relação entre campo e cidade na história e na literatura, além da caracterização do herói da decadência. Assim, com base na representação que os textos teóricos e literários oferecem e mediante a análise da obra de Dyonélio, visa-se a discorrer sobre a mutação do mito do gaúcho herói a partir das transformações do espaço, da subversão de valores e da imposição de novas normas de conduta a que é submetido Naziazeno no espaço urbano.

Versões controversas na leitura de arquivos: o Museu Penitenciário Paulista
Authors: Massmann Débora
Published: December 2018

Este trabalho analisa o processo de produção de sentidos em um espaço simbólico muito específico, a saber, o Museu Penitenciário Paulista (MPP). A partir do dispositivo teórico-analítico da Análise de Discurso, compreendeu-se que o museu, como arquivo e como interdiscurso, se configura na relação com o espaço urbano, com as instituições e com as condições de produção (artefatos, visitantes, etc.). As análises apontam para as versões controversas que são postas em funcionamento pelo Museu Penitenciário Paulista na produção de um discurso autoritário em que a única versão aceita, aparentemente, é aquela do Estado.
Determinants of the Government Bond Yield: Evidence from a Highly Euroised Small Open Economy
Authors: Mihelja Žaja Maja , Jakovčević Drago , Višić Lucija
Published: December 2018

This paper analyses the relationship between bond market, macroeconomic fundamentals and a set of additional covariates in the Republic of Croatia, a small open economy with a very high and persistent level of euroization. The sample ranges from the year 2001 to 2017. Ordinary least squares regression is applied on the quarterly dataset to examine the major drivers of nominal yields of government bonds, whereas Multiple Breakpoint Tests are used to determine structural breaks in the variables. The results corroborate theoretical knowledge and suggest a significant effect of fiscal and financial determinants on bond yields. Variables presenting macroeconomic fundamentals explain a substantial part of Croatian trends. Therefore, policymakers seeking to improve macroeconomic conditions should learn from multi-causal studies involving these variables before setting their policies.

Environmental uncertainty is increasing day by day in increasing competition conditions. Under the uncertainty, corporate executives are confronted with the problem of taking long-term strategic decisions that are both instantaneous and capable of maintaining their assets. Particularly under uncertainty, limited information and focusing on short term and near environment are the most important problems faced by the sustainability of today's companies.The aim of this study is to create a model where managers can create organizational structures that can turn environmental uncertainty into a risk by positively affecting organizational performance. As a result of the study, it has been observed that the institutions where the bottom-up and horizontal information flow structures are formed and the centralization levels are reduced have more detailed information in the sectoral framework and the organizational performance perceived in the context of innovation, quality and productivity has increased.
