Measures of social segregation in the context of Warsaw, Berlin and Paris metropolitan areas
Authors: Grzegorczyk Anna , Jaczewska Barbara
Published: November 2015

Social segregation is a subject common in contemporary studies of metropolitan areas. Until recently, studies of segregation focused on the distribution of ethnic groups, immigrants, and the poor. Today, they also cover additional indicators such as demographic properties, education, and affiliation with social and professional categories, which can also serve to determine the causes of the segregation (including the self-segregation of the rich). This article aims to point out the measures of segregation that present the segregation levels in the most complete manner, along with their application in the context of three European metropolitan areas: Warsaw, Berlin, and Paris. The first part of the article is a review of the existing approaches to segregation measures, followed by the selection of research method, presentation of the analysis’ results, and evaluation of the applied methods; presenting the opportunities and limitations in research of the social segregation phenomenon.
Regional economic resilience: concepts, empirics and a critical review
Authors: Tóth Balázs István
Published: November 2015

Regional (economic) resilience and resilient thinking have gained considerable attention in recent years. My aim with this work is to throw light on some of the underlying aspects of regional economic resilience and resilient thinking. In the current study I give an overview of the notion, key concepts, main empirical results and planning tasks concerning regional (economic) resilience as well as outlining some of the criticisms. Finally, I provide some suggestions for studies in resilience and resilient thinking for future research agendas. The main results of the study is my own belief in the concept of regional economic resilience, and an overview and comparison of regional (economic) resilience literature and empirics that lead me to highlight some of the shortcomings of the research topic.
Driving under the influence…..”Of social factors”
Authors: Arthur Robert M.
Published: November 2015

The bulk of the research that seeks to understand driving behavior and decision making has been performed by behavioral psychologists and engineers. These studies have a tendency to focus on the individual driver, examining such topics as road and vehicle design, cognitive skills, and the effects of collisions on the human body. This disparate research has produced a wealth of knowledge but with little unifying theory. The act of driving occurs within social environments that exist at many levels; the same act can be viewed through multiple lenses. In its exploration of the social context, this paper moves from an analysis of the global scale to the regional to the local. Our roads are monitored by police services and illegal acts are punished by judicial systems; these social institutions attempt to modify behavior through punitive measures. These punitive measures are derived from social theories of deviance and deterrence, methods shown here to be flawed. Empirical data derived from observations in Al Ain, UAE, are used in a quasi-experimental design that describes how drivers alter their choice of speed based on their observations of other drivers. This paper concludes by suggesting that, both by examining and legislating for driver behavior, there is a pressing need to situate the driver within his/her social environment.
The peripheries of development: development and labour in circumstances of constant shortages, as exemplified by the Frías district of Peru*
Authors: Czerny Miroslawa , Córdova-Aguilar Hildegardo , Rzucidło Anna
Published: November 2015

Empirical research into social vulnerability – and into strategies that allow people to persist or secure their existence – has most often concerned itself with peripheral, poorly-developed regions with a long history of shortages; frequently even ones in which a failure to solve socio-political problems over decades or even centuries, manifests itself in a permanent crisis. One such region is north–western Peru, presented in this article by the authors who have proceeded on the assumption that the socioeconomic development of the country’s mountainous areas (including Frías, the district selected for study) not only reflects a peripheral location as regards central areas of Peru and the department of Piura, but is also an outcome of the workings of political and environmental factors that do not help sustain (or in many cases even obstruct) processes of development.
Dialect and stance-taking by non-Egyptian celebrities in Egypt
Authors: Bassiouney Reem
Published: November 2015

This article explores the stance of non-Egyptian celebrities performing in Egyptian Colloquial Arabic (ECA) and/or living in Egypt. These celebrities are forced by the Egyptian media to take a stance towards ECA and Egypt, and engage in the ongoing dialogue concerning Egypt’s cultural role. Meta-linguistic, as well as linguistic, resources become the focal point of a struggle for dominance. Over the last five years, there have been intense debates regarding the role of Egypt as a cultural hub in relation to the Egyptian media. This is due to the increasing threat from other emerging cultural hubs – such as Dubai and Lebanon – both of which have greater financial resources and allow the use of other Arabic dialects. The data utilised for this research includes television and newspaper interviews, articles, as well as performances by non-Egyptians. One particularly relevant example is that of Russian/Armenian belly dancer Ṣāfināz who currently resides in Egypt.
Meaningfulness, the unsaid and translatability: Instead of an introduction
Authors: Keidan Artemij
Published: November 2015

The present paper opens this topical issue on translation techniques by drawing a theoretical basis for the discussion of translational issues in a linguistic perspective. In order to forward an audienceoriented definition of translation, I will describe different forms of linguistic variability, highlighting how they present different difficulties to translators, with an emphasis on the semantic and communicative complexity that a source text can exhibit. The problem is then further discussed through a comparison between Quine's radically holistic position and the translatability principle supported by such semanticists as Katz. General translatability — at the expense of additional complexity — is eventually proposed as a possible synthesis of this debate. In describing the meaningfulness levels of source texts through Hjelmslevian semiotics, and his semiotic hierarchy in particular, the paper attempts to go beyond denotative semiotic, and reframe some translational issues in a connotative semiotic and metasemiotic perspective.
A Holistic And Integrative Concept For Strong-Motion Records On Constructions Of The URBAN-INCERC National Seismic Network
Authors: Dragomir Claudiu-Sorin , Meita Vasile , Dobre Daniela , Georgescu Emil-Sever , Borcia Ioan-Sorin
Published: November 2015

The main objective of the National Seismic Network for Constructions, operated by the National Institute for Research and Development in Constructions, Urban Planning and Spatial Territorial Development “URBAN-INCERC”, is the monitoring of situations generated by earthquakes or other dangerous sources of vibrations induced in constructions on the entire Romanian territory. The NIRD URBAN-INCERC seismic records obtained in-situ and on buildings were and are extremely important for designers, especially in 1977, 1986 and 1990. It is the largest network in Romania, consisting of some 60 digital acceleration recorders distributed in Bucharest and in the country. This network is strategic from the population safety point of view. Due to the specific seismic hazard and vulnerability, our country shall be in preparation for the impact of a possible earthquake, which cannot be predicted in time domain, but it is possible to occur anytime. To prevent and mitigate negative consequences of such an event, urgent actions are required to ensure structural safety. Given the facts, Romania is in a critical time on strategic options regarding the seismic risks.

Presently, a urgent necessity is the seismic network function in order to get as much as possible strong-motion data for advanced research and to understand why damages in buildings occurred. The next goal is to have more parametric and spectral data for engineering design, as well as to improve the zoning maps, having more stations at reduced distances. If possible, strong-motion micro-zonation data would explain some specific shaking differences, as a future option for local arrays.

The paper presents the necessity, means and requirements of achieving a holistic and integrative concept for the national seismic network of constructions, taking into account geological settings, environmental and local soil conditions on regional profiles, attenuation patterns, architectural and structural patterns, and number of seismic stations in specific seismic zones. Also, a case study of building seismic instrumentation in Bucharest according to the Romanian Seismic Design code, indicative P100-1:2013.
The Historical Flood Of July 2008 From Vaser River Basin, Romania. Causes, Effects And Flood Control Actions
Authors: Sima Andrei , Șerban Gheorghe
Published: November 2015

Floods is an experience perceived by society as unexpected, unexplainable and traumatizing and nowadays a threat to humanity more than ever. Among the natural phenomena which negatively affect human activities, floods are the ones which usually have the most significant consequences. The research, evaluations and statistics related to these phenomena do not reveal the drama and serious consequences that come with floods. It was proven that the increase of these extreme hydrological phenomena it is closely related to the anthropic activities from the area. Vaser basin is the most significant sub-basin of Vișeu river basin, contributing with 28% from the total flow of Vișeu river. Having a strong touristic and economic potential, the basin is often threatened by flash floods which usually have devastating effects. During July 2008 there was recorded the most significant flood from the history of hydrometric activity that led to substantial damage and death among locals. The present paper aims to analyze this historical flood, identifying the causes, effects, as well as the methods to control this extreme hydric phenomenon.
The Impact Of Ten Weeks Of Bodyweight Training On The Level Of Physical Fitness And Selected Parameters Of Body Composition In Women Aged 21-23 Years
Authors: Lipecki Krzysztof , Rutowicz Bartosz
Published: November 2015

Introduction
. The aim of the study was to assess the impact of 10 weeks of bodyweight training on selected elements of body composition (body mass, muscle mass, and the percentage of body fat and water) and components of physical fitness (strength, strength endurance, flexibility, and aerobic capacity) of women aged 21-23 years who do not practise sports professionally.

Material and methods
. The study involved 15 women whose mean age was 22 years 2 months. Their body mass and composition were assessed using a TANITA BC-1000 scale, and the following parameters of physical fitness were measured: the strength and power of the upper and lower extremities; the strength endurance of the shoulders, shoulder girdle, and trunk; as well as their flexibility and physical capacity. The assessment was performed twice, that is before and after the completion of the 10-week programme.

Results
. The study revealed that the 10-week bodyweight training programme had caused a minor increase in body mass (1.16%) and body fat percentage (2.43%), while muscle mass and body water percentage had not changed. As far as physical fitness is concerned, the bodyweight exercises had had a positive impact on all of the elements of physical fitness which were measured, including statistically significant increases in the explosive strength of the lower extremities (5.6%; p<0.01), strength endurance of the trunk (10.7%; p<0.01), and aerobic capacity (33.3%; p<0.05).

Conclusions
. Without a properly balanced diet and nutrition control, the bodyweight training programme had a small impact on the parameters of body composition. It was, however, an effective way of enhancing general physical fitness: apart from improving muscle strength and endurance, it also increased physical capacity and flexibility.
An Assessment Of The Physical Activity Of Adults Residing In The Świętokrzyskie Region
Authors: Jopkiewicz Andrzej , Gawron Jacek
Published: November 2015

Introduction
. The aim of the study is to assess the physical activity of adults residing in the Świętokrzyskie region in Poland with relation to age, gender, and socioeconomic factors such as the level of education, place of residence, and financial situation.

Material and methods
. The survey questionnaire used to assess physical activity was prepared by the Department of Auxology of Jan Kochanowski University in Kielce. The study group involved a total of 1,032 persons, aged 20-59 years, including 517 women and 515 men. The results of the study were subjected to statistical analysis. Two tests were carried out to determine the correlations between variables: Spearman's rank correlation coefficient was calculated and the nonparametric chi-square test (x2) was used.

Results
. It was found that the leisure-time physical activity of the adults residing in the Świętokrzyskie region who participated in the study was insufficient and remained at a low level. Particularly alarming is the fact that a low level of leisure-time physical activity was found for young persons, both male and female, aged 20-39 years. This low level of activity also prevailed in the older age groups. Apart from age, gender, and the level of education, the place of residence and financial situation significantly impacted the physical activity of the adults.

Conclusions
. It was observed that the physical activity of men and women aged 20-59 years in their leisure time was the greater the bigger the size of the agglomeration they resided in, the higher their level of education, and the better their financial situation.
Virtual fractional flow reserve assessment in patient-specific coronary networks by 1D hemodynamic model
Authors: Gamilov Timur M. , Kopylov Philippe Yu. , Pryamonosov Roman A. , Simakov Sergey S.
Published: November 2015

Atherosclerotic diseases of coronary vessels are the main reasons of myocardial ischemia. The value of the fractional flow reserve (FFR) factor is the golden standard for making decision on coronary network surgical treatment. The FFR measurements require expensive endovascular diagnostics. We propose a noninvasive method of the virtual FFR assessment in patient-specific coronary network based on angiography and computer tomography data. Also we analyze sensitivity of the model to the heart stroke volume.
“Money. Armed. Quietly”: An analysis of criminogenic prose in institutional holdup notes
Authors: Arntfield Michael
Published: November 2015

This paper examines an Anglophonic corpus of institutional holdup notes (n=29) recovered by robbery detectives in a single Canadian city over a twenty-year period. Moreover, it examines how the recurrence of specific lexical structures in written content reflects a given offender’s awareness of his social position relative to both his victim and the institution where a robbery is committed. By disaggregating holdup notes into three distinct categories based on written content, it is argued that these categories reflect the willingness of perpetrators to adjust the content of these notes through a process of linguistic code switching that both enables and expedites the completion of the offence. It is additionally argued that the perceived formality of the institution targeted by perpetrators has an unconscious but direct bearing on the formality and structure of their writing.
Políticas y lugares de la memoria. La reconstrucción del pasado en el presente. El caso del Espacio Mansión Seré en Buenos Aires, Argentina.
Authors: Escolar Cora , Fabri Silvina
Published: November 2015

Nos proponemos en este artículo reflexionar acerca de lo tendencialmente infinita que es la reconstrucción del pasado en el presente. De ahí, que en un primer momento, estimamos significativo hablar sobre los “lugares de memoria”, para debatir la relación entre la memoria y el olvido. Esos lugares que, habitualmente, cumplen una función de simbolización, articulan nuevos sentidos y significaciones con el fin de conmemorar/rememorar el pasado reciente. Es en el caso de la ex Mansión Seré donde pensamos centrar nuestra atención. En este sentido, el espacio conmemorativo plantea la posibilidad de reflexionar sobre las políticas de la memoria, el hacer institucional y el modo en el que ambos se conjugan.
A fragmentação da documentação ferroviária: uma perspectiva legal
Authors: Matos Lucina Ferreira
Published: November 2015

Este ensaio debate as diretrizes relativas à preservação do acervo documental da Rede Ferroviária Federal S.A. (RFFSA), após a sua extinção. Considero as condições a qual esse patrimônio está sujeita como promotora de um risco eminente de perda da memória ferroviária e brasileira. Há uma referência significativa de relato de casos de danos infringidos aos documentos, tanto por agentes públicos quanto particulares, ocasionando uma perda irreparável. Os cuidados estão descritos na legislação que respalda a extinção da empresa, mas não garante a salvaguarda desses bens. Para demostrar essa problemática, descrevo sucintamente, neste trabalho, o processo de desestatização, as diretrizes para o recolhimento do acervo e as competências dos novos responsáveis. Utilizo como respaldo teórico as bases disciplinares da Arquivologia e as práticas aplicadas pelos órgãos responsáveis pelas políticas documentais no país – o Conselho Nacional de Arquivos e o Arquivo Nacional.

Case Reports of Aripiprazole Causing False-Positive Urine Amphetamine Drug Screens in Children
Authors: Kaplan Justin , Shah Pooja , Faley Brian , Siegel Mark E.
Published: November 2015

Urine drug screens (UDSs) are used to identify the presence of certain medications. One limitation of UDSs is the potential for false-positive results caused by cross-reactivity with other substances. Amphetamines have an extensive list of cross-reacting medications. The literature contains reports of false-positive amphetamine UDSs with multiple antidepressants and antipsychotics. We present 2 cases of presumed false-positive UDSs for amphetamines after ingestion of aripiprazole. Case 1 was a 16-month-old girl who accidently ingested 15 to 45 mg of aripiprazole. She was lethargic and ataxic at home with 1 episode of vomiting containing no identifiable tablets. She remained sluggish with periods of irritability and was admitted for observation. UDS on 2 consecutive days came back positive for amphetamines. Case 2 was of a 20-month-old girl who was brought into the hospital after accidental ingestion of an unknown quantity of her father’s medications which included aripiprazole. UDS on the first day of admission came back positive only for amphetamines. Confirmatory testing with gas chromatography–mass spectrometry (GC-MS) on the blood and urine samples were also performed for both patients on presentation to detect amphetamines and were subsequently negative. Both patients returned to baseline and were discharged from the hospital. To our knowledge, these cases represent the first reports of false-positive amphetamine urine drug tests with aripiprazole. In both cases, aripiprazole was the drug with the highest likelihood of causing the positive amphetamine screen. The implications of these false-positives include the possibility of unnecessary treatment and monitoring of patients.
X-linked Agammaglobulinemia With Normal Immunoglobulin and Near-Normal Vaccine Seroconversion
Authors: Preece Kahn , Lear Graeme
Published: November 2015

We present a 22-month-old boy with X-linked agammaglobulinemia masked by normal immunoglobulin levels and vaccine seroconversion. Diagnosis was made after strong clinical suspicion of immune deficiency led to identification of markedly reduced B-cell numbers and confirmation with identification of a novel Bruton tyrosine kinase gene mutation. He was commenced on replacement immunoglobulin therapy with excellent clinical improvement. This case highlights the variability of phenotypic presentation and apparent disunity between routine immunologic investigations and severe disease in X-linked agammaglobulinemia, necessitating clinical acumen to make the diagnosis.

Authors: O’Leary Sean T. , Allison Mandy A. , Fisher Allison , Crane Lori , Beaty Brenda , Hurley Laura , Brtnikova Michaela , Jimenez-Zambrano Andrea , Stokley Shannon , Kempe Allison
Published: November 2015

BACKGROUND AND OBJECTIVES:

Physicians dismissing families who refuse vaccines from their practices is controversial. We assessed the following among pediatricians (Peds) and family physicians (FPs): (1) reported prevalence of parental refusal of 1 or more vaccines in the infant series; (2) physician response to refusal; and (3) the association between often/always dismissing families and provider/practice characteristics and state exemption laws.

METHODS:

Nationally representative survey conducted June to October 2012. A multivariable analysis assessed association of often/always dismissing families with physician/practice characteristics, state philosophical exemption policy, and degree of difficulty obtaining nonmedical exemptions.

RESULTS:

The response rate was 66% (534/815). Overall, 83% of physicians reported that in a typical month, ≥1% of parents refused 1 or more infant vaccines, and 20% reported that >5% of parents refused. Fifty-one percent reported always/often requiring parents to sign a form if they refused (Peds 64%, FP 29%, P < .0001); 21% of Peds and 4% of FPs reported always/often dismissing families if they refused ≥1 vaccine. Peds only were further analyzed because few FPs dismissed families. Peds who dismissed families were more likely to be in private practice (adjusted odds ratio [aOR] 4.90, 95% confidence interval [CI] 1.40–17.19), from the South (aOR 4.07, 95% CI 1.08–15.31), and reside in a state without a philosophical exemption law (aOR 3.70, 95% CI 1.74–7.85).

CONCLUSIONS:

Almost all physicians encounter parents who refuse infant vaccines. One-fifth of Peds report dismissing families who refuse, but there is substantial variation in this practice. Given the frequency of dismissal, the impact of this practice on vaccine refusers and on pediatric practices should be studied.
Análisis de estabilidad y adaptabilidad de híbridos de maíz de alta calidad proteica en diferentes zonas agroecológicas de Colombia
Authors: Vargas Escobar Ever Andrés , Baena García Diosdado , Vargas Sánchez José Ever
Published: November 2015

La energía es el mayor aporte del maíz (Zea mays) para la producción de alimentos de consumo humano y animal.  Desde 1896 se ha tratado de incrementar el nivel de proteína en este cereal, no obstante fue en la década de 1960 cuando se obtuvo un gran avance con el hallazgo del gen opaco o2.  Este gen, en su esta-do recesivo, hace que la calidad proteica del maíz aumente, debido al incremento en el contenido de glo-bulinas y la reducción de zeínas.  Los maíces conocidos como QPM (Quality Protein Maize) duplican la cantidad de lisina y triptófano cuando se comparan con maíces de endospermo normal.  Una meta posible es obtener QPM de alto rendimiento de grano, con buena sanidad y adaptados a diferentes condiciones ambientales.  En el este trabajo se probaron nueve híbridos amarillos QPM, desarrollados por la Federa-ción Nacional de Cultivadores de Cereales y Leguminosas (Fenalce) con germoplasma cedido por el Centro Internacional de Mejoramiento de Maíz y Trigo (CIMMYT) y un testigo comercial de endospermo normal, en 17 ambientes de seis zonas agroecológicas de Colombia:  Caribe Húmedo, Caribe Seco, Orinoquía, Valle del Río Cauca, Valle del Río Magdalena y Zona Cafetera.  En un diseño de bloques completos al azar y cuatro repeticiones, se midieron variables de planta, componentes del rendimiento y contenido de triptó-fano.  Los análisis de estabilidad y adaptabilidad se basaron en el rendimiento de grano usando los mode-los estadísticos de Eberhart y Russell, Lin y Binns y AMMI.  El híbrido QPM 303 sobresalió en todos los ambientes y el QPM 305 en ambientes poco favorables.  Ambos conservan sus características bioquímicas de calidad proteínica y son estables en los ambientes donde fueron evaluados, según los modelos estadísticos utilizados.

Published: November 2015

El género Ocimum con más de 150 especies se caracteriza por la gran variabilidad morfológica y quimiotípica y el gran valor en la industria de perfumería, cosmética, alimentaria y farmacéutica. Con el objetivo de evaluar la calidad fisiológica de las semillas de Ocimum spp, en el Centro Experimental y el laboratorio de Fisiología Vegetal de la Universidad Nacional de Colombia, ubicada en el municipio de Palmira, se realizaron pruebas de viabilidad en tetrazol y germinación. En ensayos factoriales completamente al azar y tres repeticiones, en semillas de cinco variedades de Ocimum se evaluó el efecto de embeberlas durante cinco minutos en Nitrato de potasio KNO3 al 0.2% y ácido giberélico AG3 a 250 ppm y 500 ppm y un testigo (agua). Los resultados mostraron que las semillas de la especie O. selloi presentaron los mayores porcentajes (90 %) de viabilidad en tetrazolio TTZ y germinación (46,2 %). Las semillas embebidas en KNO3 al 0,2 % presentaron los mayores valores de germinación en semillas de tres de las cinco variedades evaluadas. Las mejores respuestas de germinación se obtuvieron con las semillas de las especies O.selloi (70%) y O, micranthum (58%), seguido de Ocimum sp. (26%). Los resultados indicaron la presencia de niveles variables de latencia, que fue superada parcialmente con los tratamientos de germinación evaluados especialmente nitrato de potasio (KNO3).
Hormigas asociadas a nectarios extraflorales de árboles de dos especies de Inga en cafetales de Cauca, Colombia

Published: November 2015

En dos fincas cafeteras localizadas en la vereda Villanueva, municipio de Popayán; Colombia, se identificó la comunidad de hormigas presentes en los nectarios extraflorales de árboles de guamo (Inga edulis e I. densiflora) utilizados como sombra en cafetales, y sobre la hojarasca del suelo.  Las recolecciones se realizaron con cebos, extracción de hojarasca con sacos mini-Winkler y captura manual.  Se encontraron 43 especies, distribuidas en 17 géneros y siete subfamilias.  Los resultados mostraron que las especies de hormigas que habitan en los árboles son diferentes a las que habitan en la hojarasca, pero gracias a sus hábitos forrajeros algunas especies se desplazan de un estrato al otro.  Se concluye que los árboles de sombrío como el guamo son importantes tanto para el mantenimiento de las interacciones mutualistas hormiga–planta, como para la conservación de la diversidad; además, la presencia de árboles puede contribuir indirectamente a la prestación de servicios ecosistémicos fitosanitarios, ya que algunas especies de hormigas de los géneros Crematogaster y Camponotus pueden servir como potenciales agentes de control biológico para insectos plaga.
Efecto de la aplicación de zeolita en la recuperación de nitrógeno y el rendimiento de maíz
Authors: Obregón Portocarrero Nicolas , Díaz Ortíz Jaime Ernesto , Daza Martha Constanza , Aristizabal Rodríguez Héctor Fabio
Published: November 2015

La baja eficiencia de la fertilización nitrogenada ocasiona altos costos de producción y contaminación ambiental por lo que estrategias como la aplicación de zeolitas pueden reducir pérdidas de nitrógeno (N) en sistemas productivos. Empleando un diseño experimental de bloques completos al azar con cuatro repeticiones, se evaluó el efecto de la aplicación de zeolita (clinoptilolita) en la recuperación de nitrógeno (N) y el rendimiento de maíz (Zea Mays L.) mediante la adición del mineral (15, 25 y 35 kg ha-1) y de 100kg/ha de N proveniente de urea. El aporte de zeolita incidió significativamente (P<0.05) en el rendimiento del cultivo, altura de plantas y diámetro del tallo. Los indicadores de eficiencia de uso del nutriente reportaron aumentos en el N recuperado del fertilizante, mejorando su aprovechamiento y la efectividad económica de la urea. El análisis del suelo al final del ciclo del cultivo mostró que la aplicación de zeolita favoreció la adsorción de fósforo, magnesio y potasio, mejoró la CIC e impactó el pH del suelo. Aunque la eficiencia de recuperación de nitrógeno no excedió el 60%, se observaron diferencias importantes en la recuperación de nitrógeno entre etapas fenológicas del cultivo, lo cual es relevante para el manejo nutricional eficiente.
Efecto del viento en la dispersión a corta distancia del parasitoide Amitus fuscipennis MacGown y Nebeker (Hymenoptera: Platygasteridae) en cultivos de fríjol y habichuela
Authors: Hernandez Mahecha Luis Miguel , Manzano Maria Del Rosario
Published: November 2015

El parasitoide Amitus fuscipennis MacGown y Nebeker (Hymenoptera: Platygasteridae) es un agente de control biológico promisorio de la mosca blanca de los invernaderos Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae), no obstante no se conoce la distancia ni el efecto del viento en la dispersión del parasitoide en cultivos. Por tanto, el objetivo de este estudio fue determinar la distancia y dirección del proceso inicial de dispersión de A. fucipennis en cultivos de frijol y habichuela infestados con T. vaporariorum. Adultos del parasitoide fueron marcados con fluorocromo rojo y recapturadas en tram-pas pegajosas amarillas de 1, 1.5 y 2 m de altura ubicadas a 4, 8 y 12 m de distancia del punto de libera-ción, respectivamente. Los resultados mostraron que A. fuscipennis se dispersó hasta 12 m sin diferencias (P > 0.05) en el promedio de adultos recapturados en las tres distancias probadas. La tasa promedio de recaptura fue de 2.06 % y la mayor tasa ocurrió en dirección Este (15.08%) lo que sugieren que el parasi-toide se dispersa más de 12 m y que el viento contribuye a la dispersión pasiva una vez que el insecto ini-cia el vuelo. El parasitoide se dispersó preferiblemente en la dirección del viento predominante en latitu-des bajas de los Andes. Estos aspectos son relevantes al momento de liberar A. fuscipennis en un agro-paisaje andino con combinación de cultivos atacados y no atacados por T. vaporariorum para disminuir la dispersión del parasitoide hacia otros cultivos.
Small non-volant mammals (Didelphimorphia and Rodentia) from the RPPN Guarirú, an Atlantic Forest fragment in northeastern Brazil
Authors: Carvalho Mateus Souza de , Oliveira Téo Veiga de
Published: November 2015

Due to the very rare mammal inventories in the northern half of the Atlantic Forest in the state of Bahia, Brazil, all initiatives to increase the knowledge of the group in this region are greatly appreciated. Thus, herein we present an inventory conducted in the privately owned Guarirú Nature Reserve, a fragment of Atlantic Forest in several conservation/regeneration stages. Sampling was carried out using Tomahawk, Sherman, and Pitfall traps over one year. The sampling resulted in 154 captures of 93 individuals from 12 different species. The didelphids Didelphis aurita, Gracilinanus microtarsus, Marmosa murina, Marmosops incanus, Metachirus nudi­caudatus, Micoureus paraguayanus, and Monodelphis americana were recorded, as well as the cricet­ids Akodon cursor, Oligoryzomys sp., and Rhipidomys sp., and the echimyids Trinomys albispinus and T. setosus. Given the relative lack of knowledge about this important portion of the Atlantic Forest this inventory is an important contribution to the mammalogy of Brazil.

Recent records of bird species in the Colombian Andes have shown that this region is not as well known as was previously believed. We compiled data from a major collection of Colombian birds and from our recent field observations to complement the bird species list of Quindío department. We report the addition of 14 species to Quindío’s checklist and data of museum vouchers for 12 species reported only from field observations. The majority of additions were from localities below 1,900 m above sea level, a zone that has been highly transformed by human activities. Our dataset, and other information, raised the number of bird species in Quindío to 560. This information must be considered in decisions about the land use in this region of the Colombian Andes.

Field research was conducted to evaluate the efficacy of preplant herbicides commonly used in no-till corn and soybean production and to determine the efficacy of three application timings in the spring for star-of-Bethlehem bulb management. A single, preplant application of herbicide treatments that included flumioxazin, sulfentrazone, or paraquat resulted in 91 to 97% control of star-of-Bethlehem at 14 d after treatment (DAT). Star-of-Bethlehem control from atrazine and metribuzin was moderate (70 to 75%) at the Marion location but poor (< 20%) at Murphysboro. Regardless of the initial foliar control at 14 DAT from treatments included in the corn and soybean herbicide screen, only applications containing paraquat resulted in extensive control (75 to 86%) of star-of-Bethlehem foliar regrowth by 1 yr after treatment. Star-of-Bethlehem was most responsive to herbicide applications in mid-March in southern Illinois when compared with applications made March 1 and April 11. The mid-March application timing corresponded to the vegetative reproductive stage, approximately 3 wk prior to flowering. The average density of star-of-Bethlehem bulbs in nontreated plots occupied 7.9% of the field soil volume in the upper 7.6 cm of the soil profile. Spring applications of paraquat (repeated 2 yr consecutively) reduced bulb density in the soil by 88%, compared with 5% or less bulb reduction for consecutive applications of glyphosate or 2,4-D ester applied alone. Overall, paraquat and paraquat tank mixtures provided the most effective and consistent control of star-of-Bethlehem foliage and underground bulbs, which is paramount for long-term management of this invasive species.

Sprayer applicator-controlled variables, such as nozzle selection and spray volume, will become increasingly important for making labeled POST applications of dicamba in next-generation cropping systems. A field experiment was conducted in 2013 and 2014 at the Northeast Research and Extension Center in Keiser, AR. Tank mixtures of Engenia (a new form of dicamba), glyphosate, glufosinate, andS-metolachlor were applied with TeeJet AIXR, AITTJ60, and TTI nozzles. Two nozzle sizes, 11003 and 11006, were used to vary spray volume from 94 L ha−1to 187 L ha−1, respectively. For barnyardgrass, a significant decrease in control was observed when spray volume was reduced for glyphosate + dicamba in 2013. In 2014, an overall decrease in control was observed for the TTI nozzle when spray volume was reduced to 94 L ha−1, averaged across all herbicide treatments. The addition of the productS-metolachlor to glyphosate + glufosinate + dicamba significantly reduced the droplet spectra for all nozzle types. For example, addingS-metolachlor into the tank-mix decreased the volume median diameter (Dv50) for the TTI nozzle at 187 L ha−1spray volume from 789 μm to 570 μm. The results from this research demonstrate that using low spray volume and coarser nozzles could reduce efficacy of the herbicides on the weed species evaluated. Nozzle selection and spray volume have key roles in maximizing efficacy of POST applications in dicamba-resistant crops. Additionally, evaluating droplet spectra of potential dicamba-containing tank-mixtures is critical for producing the desired droplet size to minimize off-target movement.

Sprayer applicator–controlled variables, such as nozzle selection and ground speed, will become increasingly important for making labeled POST applications of dicamba in next-generation cropping systems. Typically, nozzle orifice sizes and ground speeds differ greatly between small-plot research applications, from which efficacy recommendations are made, and commercial field applications. However, little research has been conducted to compare applications made with backpack sprayers and tractor sprayers. Thus, a field experiment was conducted in 2013 and 2014 at the Northeast Research and Extension Center in Keiser, AR. Tank mixtures of Engenia™ (N, N-Bis-(aminopropyl) methylamine form of dicamba), Liberty (glufosinate-ammonium), and Liberty + Engenia were applied with TeeJet XR, TT, AIXR, AI, and TTI nozzles at 5 km h−1and 20 km h−1. Two nozzle sizes (110015 and 11006 rated at 0.58 L min−1and 2.27 L min−1at 276 kPa, respectively) were used to keep spray volume constant at 141 L ha−1, whereas ground speed was varied. Weed control ratings were typically lower at 5 km h−1than at 20 km h−1. For example, Palmer amaranth control 4 WAT in 2013 with glufosinate and the TTI nozzle was 89% at 5 km h−1and 96% at 20 km h−1. More differences between speeds were observed for the coarser nozzles, such as the TTI and AI, as opposed to finer nozzles, such as the XR and TT. Results from this research suggest increasing orifice size increases droplet size and that other factors related to applications at faster speeds (e.g., higher droplet velocity, disruption of the crop canopy) may influence the efficacy of herbicide applications. However, increasing ground speed is not a recommended means for increasing efficacy of herbicide applications.
Biased Shorts: Short Sellers' Disposition Effect and Limits to Arbitrage
Authors: von Beschwitz Bastian , Massa Massimo
Published: November 2015

We investigate whether short sellers are subject to the disposition effect using a novel dataset that allows to identify the closing of short positions. Consistent with the disposition effect, short sellers are more likely to close a position the higher their capital gains. Furthermore, stocks with high short sale capital gains experience negative returns, suggesting that their disposition effect has an effect on stock prices. A trading strategy based on this finding achieves significant three-factor alphas. Overall, short sellers’ behavioral biases limit their ability to arbitrage away the mispricing caused by the disposition effect of other market participants.
Securitization and Credit Quality

Banks are usually better informed on the loans they originate than outside investors. As a result, securitized loans might be of lower credit quality than — otherwise similar — non-securitized loans. We assess the effect of securitization activity on credit quality employing a uniquely detailed dataset from the euro-denominated syndicated loan market. We find that, at issuance, banks do not select and securitize loans of lower credit quality. Following securitization, however, the credit quality of borrowers whose loans are securitized deteriorates by more than those in the control group. We find tentative evidence suggesting that poorer performance by securitized loans might be linked to banks’ reduced monitoring incentives.

Published: November 2015

Pretende apresentar-se a versão portuguesa do REHACOP (Ana Paula Couceiro Figueira, Rui Paixão, et al., sd), um programa de intervenção neuropsicológica, espanhol (Ojeda, N., Peña, J., Bengoetxea, E., & García, A., da Universidade de Deusto, País Basco). O REHACOP (2012, apresentação pública oficial), originalmente, assume-se como um programa de reabilitação neuropsicológica de psicoses e esquizofrenia. Resulta de um longo trabalho, de vários anos, de vários especialistas em neuropsicologia, com mais de 18 anos de experiência na área, e várias vezes premiado. Todavia, neste momento, os autores da versão original, espanhola, têm projetos de utilização com outras populações (crianças, adolescentes e idosos). O mesmo será e está a ser tentado em Portugal. Trata-se de um programa integral e estruturado, constituído por 8 módulos de intervenção: atenção, linguagem, aprendizagem e memória, funções executivas, atividades da vida diária, competências sociais, cognição social e psicoeducação. O programa é composto por um total de 300 exercícios de intervenção, acessíveis de administração, com instruções e soluções e orientações para avaliação das mudanças, fichas de seguimento e sugestões de seguimento, de tarefas para realizar em contexto familiar. As atividades ou tarefas estão estruturadas por subdomínios e por níveis de dificuldade. Os materiais são acessíveis e coloridos e incluem as instruções para os clientes e as soluções para o interventor. Pode ser utilizado em sessões individuais ou em grupo. O programa completo é composto por 2 manuais, um para o administrador/profissional e outro para o cliente.
Inteligencia emocional en el alumnado de Educación Secundaria ourensano

Published: November 2015

La actual situación de la educación secundaria obligatoria en Galicia, expuesta a numerosas reformas legislativas y estructurales, hace necesaria una profunda reflexión con la única pretensión de guiar al alumnado en tiempo de crisis. Ahora bien, la educación es un fenómeno complejo que requiere el concurso de distintos saberes a la hora de comprender y explicar sus distintas dimensiones (Martínez-Otero, 2003), reconociéndose cada vez más, la necesidad de atender educativamente la dimensión emocional del alumnado. A través de este estudio realizado a jóvenes ourensanos que cursan Educación Secundaria Obligatoria, se pretende conocer el nivel de inteligencia emocional que poseen y la influencia que puede ejercer sobre ella diferentes variables del alumnado (sexo, edad, expediente académico, estructura familiar) y de los centros educativos (ubicación, tipo y curso académico). Las variables analizadas brindan una panorámica de la inteligencia emocional en la adolescencia, al tiempo de ofrecer las claves para optimizar las actuaciones del alumnado en el proceso socioeducativo. El cuestionario utilizado, TMMS-24, tiene como objetivo la evaluación de la inteligencia emocional intrapersonal percibida evaluando los siguientes aspectos: atención de las emociones, claridad emocional y reparación emocional. La muestra quedó compuesta por 1.270 alumnos que cursan Educación Secundaria Obligatoria en la provincia de Ourense durante el curso escolar 2014-15. Se puede concluir que el alumnado muestra un mayor nivel de inteligencia emocional en relación a la dimensión regulación de las emociones (M = 3.39), mostrándose más deficitarias las restantes dimensiones: percepción emocional (M =3.01) y comprensión de sentimientos (M = 3.07). Según los datos obtenidos, las puntuaciones medias más altas alcanzadas en la percepción emocional se detectan en el alumnado que tiene 16 años, mujer, repetidora, vive en un ambiente familiar desestructurado, y cursa 3º de ESO en un centro rural concertado; en la compresión de sentimientos, se presentan a la edad de 12 años, en varones que aprueban todo, de un ambiente familiar estructurado y cursan 1º de ESO en un centro concertado del entorno urbano; y en la dimensión de regulación emocional, se detecta en la edad de 12 años, varón que aprueba toso, con un ambiente familiar estructurado y curas 1º de ESO en un centro concertado del entorno rural.
