Background Excessive speed is a primary contributing factor to young novice road trauma, including intentional and unintentional speeds above posted limits or too fast for conditions. The objective of this research was to conduct a systematic review of recent investigations into novice drivers’ speed selection, with particular attention to applications and limitations of theory and methodology. Method Systematic searches of peer-reviewed and grey literature were conducted during September 2014. Abstract reviews identified 71 references potentially meeting selection criteria of investigations since the year 2000 into factors that influence (directly or indirectly) actual speed (i.e., behaviour or performance) of young (age <25 years) and/or novice (recently-licensed) drivers. Results Full paper reviews resulted in 30 final references: 15 focused on intentional speeding and 15 on broader speed selection investigations. Both sets identified a range of individual (e.g., beliefs, personality) and social (e.g., peer, adult) influences, were predominantly theory-driven and applied cross-sectional designs. Intentional speed investigations largely utilised self-reports while other investigations more often included actual driving (simulated or ‘real world’). The latter also identified cognitive workload and external environment influences, as well as targeted interventions. Discussion and implications Applications of theory have shifted the novice speed-related literature beyond a simplistic focus on intentional speeding as human error. The potential to develop a ‘grand theory’ of intentional speeding emerged and to fill gaps to understand broader speed selection influences. This includes need for future investigations of vehicle-related and physical environment-related influences and methodologies that move beyond cross-sectional designs and rely less on self-reports.

The silver gemfish Rexea solandri is an important economic resource but vulnerable to overfishing in Australian waters. The complete mitochondrial genome sequence is described from 1.6 million reads obtained via next generation sequencing. The total length of the mitogenome is 16,350 bp comprising 2 rRNA, 13 protein-coding genes, 22 tRNA and 2 non-coding regions. The mitogenome sequence was validated against sequences of PCR fragments and BLAST queries of Genbank. Gene order was equivalent to that found in marine fishes.

The effects of plant growth conditions on concentrations of proteins, including allergens, in peanut (Arachis hypogaea L.) kernels are largely unknown. Peanuts (cv. Walter) were grown at five sites (Taabinga, Redvale, Childers, Bundaberg, and Kairi) covering three commercial growing regions in Queensland, Australia. Differences in temperature, rainfall, and solar radiation during the growing season were evaluated. Kernel yield varied from 2.3 t/ha (Kairi) to 3.9 t/ha (Childers), probably due to differences in solar radiation. Crude protein appeared to vary only between Kairi and Childers, whereas Ara h 1 and 2 concentrations were similar in all locations. 2D-DIGE revealed significant differences in spot volumes for only two minor protein spots from peanuts grown in the five locations. Western blotting using peanut-allergic serum revealed no qualitative differences in recognition of antigens. It was concluded that peanuts grown in different growing regions in Queensland, Australia, had similar protein compositions and therefore were unlikely to show differences in allergenicity.

Two complete mitochondrial genomes of the black marlin Istiompax indica were assembled from approximately 3.5 and 2.5 million reads produced by Ion Torrent next generation sequencing. The complete genomes were 16,531 bp and 16,532 bp in length consisting of 2 rRNA, 13 protein-coding genes, 22tRNA and 2 coding regions. They demonstrated a similar A + T base (52.6%) to other teleosts. Intraspecific sequence variation was 99.5% for three I. indica mitogenomes and 99.7% for X. gladius. A lower value (85%) was found for the I. platypterus mitogenomes from genbank and accredited to inadvertent inclusion of gene regions from a con-familial species in one record, highlighting the need for cautious downstream use of genbank data. © 2014 Informa UK Ltd.

Homozygosity has long been associated with rare, often devastating, Mendelian disorders1, and Darwin was one of the first to recognize that inbreeding reduces evolutionary fitness2. However, the effect of the more distant parental relatedness that is common in modern human populations is less well understood. Genomic data now allow us to investigate the effects of homozygosity on traits of public health importance by observing contiguous homozygous segments (runs of homozygosity), which are inferred to be homozygous along their complete length. Given the low levels of genome-wide homozygosity prevalent in most human populations, information is required on very large numbers of people to provide sufficient power3, 4. Here we use runs of homozygosity to study 16 health-related quantitative traits in 354,224 individuals from 102 cohorts, and find statistically significant associations between summed runs of homozygosity and four complex traits: height, forced expiratory lung volume in one second, general cognitive ability and educational attainment (P < 1 × 10−300, 2.1 × 10−6, 2.5 × 10−10 and 1.8 × 10−10, respectively). In each case, increased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months’ less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing evidence that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples5, 6, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection7, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been.

Introducción: "La investigación titulada Tiempo kairológico y tradición oculta. La recepción del pensamiento de Walter Benjamin por parte de Hannah Arendt propone el esclarecimiento de las cuestiones y de las actitudes teóricas que Hannah Arendt tomó, selectivamente, de Walter Benjamin. Ambos comparten la conciencia del colapso moral y político de la Europa de entreguerras, no menos que la desconfianza ante las categorías de juicio transmitidas por una tradición, a la que no juzgaban vinculante. Discuten los mecanismos compulsivos de la lógica y los juzgan estériles e impropios para comprender y valorar. Impugnan un concepto de historia al que consideran obsoleto e indebido para discernir el significado de las acciones e inadecuado para dar cuenta de la novedad y el acontecimiento. En consecuencia, ambos recalan en “el fragmento y la ruina”, y enaltecen eventos olvidados y des-asidos del contexto referencial habitual. Así, presentan una historiografía fragmentada, compatible con una concepción del tiempo como origen y acontecimiento o, también, como disrupción de la linealidad cronológica. A esta noción llamamos tiempo kairológico..."

El objetivo del presente estudio fue el determinar el rendimiento y adaptabilidad de tres cultivares clonales de quequisque Masaya (MY), Nueva Guinea (NG) y Apalí (AP), en la comunidad de La Poma, Masaya establecidas en época de postrera. El ensayo se estableció siguiendo arreglo del diseño de bloque completos al azar, unifactorial, con tres tratamientos y tres bloques. La parcela experimental estuvo conformada de 4 surcos de 13 m y l m de separación entre ellos, para un área de 52 m2 En cada surco se establecieron 22 plantas y una separación de 0. 6 m entre las mismas, para un total de 88 plantas por parcela, 264 por bloque y 792 totales en el ensayo. La parcela útil la conformaron los 2 surcos centrales sin incluir las primeras 5 plantas, para un total de 20 plantas evaluadas. El área del bloque fue de 156 m y el área total del ensayo de 468 m . Las variables evaluadas fueron: las morfológicas (altura de planta en cm, número de hojas, grosor del seudotallo en cm2, área foliar en cm2 y número de hijos), los componentes del rendimiento (peso promedio por cormelo en g, peso promedio de cormelos por planta en g, dimensión de cormelo en cm2 y número de cormelos); los eventos morfológicos (velocidad de brotación y ahijamiento, momento de cosecha), incidencia de enfermedades virales, fungosas y bacterianas y el efecto del DMV sobre el rendimiento. El análisis de varianza realizado a las variables morfológicas indica que: los 3 genotipos presentaron valores estadísticamente similares en las variables altura de planta, grosor del seudotallo, número de hojas y área foliar al menos en las 6 primeras evaluaciones, únicamente en variable número de hijos el clon NG obtuvo resultados estadísticamente superiores a los otros dones en estudio. El ANDEVA de los datos de los componentes del rendimiento señala que no hubo diferencias estadísticas entre los cultivares en cuanto a peso de los cormelos por planta: NG (75.26 qq/mz), AP (53,67 qq/mz) y MY (64.98 qq/mz)y dimensiones del cormelo; sin embargo, el número de cormelos por planta las plantas NG reportaron valores promedios superiores estadísticamente a los reportados por el clon MY (2.94) y AP (3. 28). El peso promedio de los cormos fue superior estadísticamente en el don MY (79.16 g) con relación a los reportados por NG (58.35g) y AP (79. 16 g). Se realizó un primer test de ELISA a las muestras de hojas de plantas que presentaban los síntomas, se encontró un 96 % de incidencia del DMV en las muestras . Considerando el total de plantas por cultivar en el ensayo, la mayor incidencia la presentó el clon NG con 47 %. Tres conteos visuales posteriores indican que los valores de plantas que presentan los síntomas. varían en cada fecha de evaluación encontrándose el cv. Apalí con los mayores valores de infección. Los conteos visuales de los síntomas de la bacteria Xanthomona campestris (Pammel) Dowson registran los mayores valores al cultivar AP con valores de 6 %, seguido del cultivar NG con 3.33% y MY con 1.66% a los 150 dds y un leve incremento a los 210 dds de 8. 33% para el AP y 5 % para los cultivares NG y MY. Los conteos visuales de los síntomas de Collectrotichum Kloesporioides (Penz) indican que los valores de reportados a los 150 dds redujeron a los 210 dds en todos los genotipos. En el caso del cultivar NG de 13.33 % en la primera fecha a 5% en la segunda, de 10 a 3.33% en el cultivar AP, y de 13.33 a 6.66% en el caso del clon MY.

Resumen: El trabajo permite reconstruir el itinerario de la reacción inmediata del ultra realismo de Walter Burley frente a la crítica nominalista, tomando base en la teoría física y particularmente, en el tema del tiempo. Entendemos que el análisis comparativo de las doctrinas de Burley y de Ockham permitirá arrojar cierta luz sobre la historia de los primeros e importantes enfrentamientos al ockhamismo, procurando conformar una intelección nueva del siglo XIV donde Burley pasaría a ser un personaje de interés al motivar la reflexión de una figura como la de Ockham. Centramos nuestro análisis en torno a dos tópicos: aquel vinculado con la determinación del concepto de tiempo y su distinción del movimiento; y en segundo término, consideraremos el problema de la unicidad o pluralidad de tiempos. El trabajo propone tentativamente que ambos autores conocieron mutuamente sus doctrinas, se leyeron y corrigieron recíprocamente; y las profundas diferencias que conforman sus sistemas deben buscarse en una fundamentación gnoseo-ontológica diversa.

Resumen: n esta intervención Carlos Galli dialoga con la valiosa ponencia del cardenal Walter Kasper resumiendo la recepción de la eclesiología conciliar desde la Argentina. Este diálogo se centra en cuatro puntos, la dialéctica liberación – libertad en el diálogo de la Iglesia con la modernidad, la recepción argentina de su eclesiología considerando las relaciones entre la fe del Pueblo de Dios y las culturas de los pueblos, la reforma evangélica radical a partir del paradigma de la conversión misionera de todo el Pueblo de Dios y de todos en el Pueblo de Dios. El género del texto une el comentario interpretativo y el diálogo teológico más constructivo que crítico.

Thin films of inorganic materials are used in diverse applications, typically in polycrystalline form due to their relatively simple production. We have used enhanced piezoresponse force microscopy to investigate the domain distribution within neighbouring grains in thin polycrystalline films of the ferroelectric-ferroelastic system lead zirconate titanate (PZT). We demonstrate that domains are organized into areas with a correlated alignment of the ferroelastic and ferroelectric domains, spanning multiple grain boundaries. We present five typical arrangements of such structures: azimuthal, radial, gradient, and short- and long- range linear domain organizations. Moreover, we discuss the mechanical and electrical constraints that dictate these structures. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
