Published: December 2017

<p><em>Este trabajo relaciona dos aspectos básicos de la evaluación en educación superior (la evaluación formativa y la evaluación por competencias) con la existencia de una Red Interuniversitaria que lleva cinco años trabajando dichos aspectos de forma sistemática. En un primer punto realizamos un análisis del estado de la cuestión sobre evaluación formativa y compartida en educación superior. En el segundo explicamos la organización y funcionamiento de la Red de evaluación formativa en docencia universitaria: finalidades, metodología básica de trabajo, diferentes acciones y líneas de trabajo establecidas: proyectos de innovación e investigación educativa, seminarios permanentes de investigación-acción, difusión de resultados, organización de congresos anuales y grupos de trabajo temáticos. También presentamos los principales resultados obtenidos, organizados en cuatro apartados: a-ventajas; b-inconvenientes, problemáticas y posibles soluciones; c-influencia en el rendimiento académico; d-carga del trabajo que supone para profesorado y alumnado. En el tercer y último apartado del trabajo explicamos los aspectos fundamentales de la evaluación por competencias en educación superior, los cambios que requiere y la importancia de la coherencia entre los elementos curriculares; en este sentido, aportamos una aplicación práctica que esperamos sea útil para lograr mayores niveles de coherencias curricular en nuestras asignaturas.</em></p><p> </p><p> </p>

Published: December 2017

<p><em>Los retos que plantea la evaluación de los aprendizajes en la formación por competencias, se hacen más ostensibles cuando nos referimos a sistemas blended-learning, cada vez más utilizados incluso por universidades presenciales. En estos sistemas, el cambio en la concepción pedagógica y de renovación metodológica en el proceso de enseñanza-aprendizaje supone un proceso muy complejo, no exento de retos y dificultades. Este artículo pretende conocer cómo se está planteando la evaluación en competencias, principalmente las genéricas, en un modelo blended-learning. Para ello, analizamos el proceso de implantación de los nuevos Grados en la UNED, en el curso académico 2009/10, desde la perspectiva del diseño de las nuevas asignaturas. Los resultados corresponden a dos fases de análisis: una de carácter cuantitativo, mediante el análisis de las guías de estudio elaboradas por los equipos docentes; y otra de carácter cualitativo, con la realización de entrevistas a responsables de la implantación de títulos y equipos docentes, para conocer sus valoraciones del proceso de adaptación al EEES. En ambos análisis se hace hincapié en el nuevo modelo de evaluación de competencias y en el uso de protocolos homogéneos, como las rúbricas.<br /></em></p><p> </p>

Published: December 2017

Abstract. Ground-based, satellite, and reanalysis datasets were used to identify two similar cyclone-induced surface ozone depletion events at Eureka, Canada (80.1° N, 86.4° W), in March 2007 and April 2011. These two events were coincident with observations of hydrogen deuterium oxide (HDO) depletion, indicating that condensation and sublimation occurred during the transport of the ozone-depleted air masses. Ice clouds (vapour and crystals) and aerosols were detected by lidar and radar when the ozone- and HDO-depleted air masses arrived over Eureka. For the 2007 event, an ice cloud layer was coincident with an aloft ozone depletion layer at 870 m altitude on 2–3 March, indicating this ice cloud layer contained bromine-enriched blowing-snow particles. Over the following 3 days, a shallow surface ozone depletion event (ODE) was observed at Eureka after the precipitation of bromine-enriched particles onto the local snowpack. A chemistry–climate model (UKCA) and a chemical transport model (pTOMCAT) were used to simulate the surface ozone depletion events. Incorporating the latest surface snow salinity data obtained for the Weddell Sea into the models resulted in improved agreement between the modelled and measured BrO concentrations above Eureka. MERRA-2 global reanalysis data and the FLEXPART particle dispersion model were used to study the link between the ozone and HDO depletion. In general, the modelled ozone and BrO showed good agreement with the ground-based observations; however, the modelled BrO and ozone in the near-surface layer are quite sensitive to the snow salinity. HDO depletion observed during these two blowing-snow ODEs was found to be weaker than pure Rayleigh fractionation. This work provides evidence of a blowing-snow sublimation process, which is a key step in producing bromine-enriched sea-salt aerosol.

Abstract. After 43 years of inactivity, the Calbuco volcano, which is located in the southern part of Chile, erupted on 22 April 2015. The space–time evolutions (distribution and transport) of its aerosol plume are investigated by combining satellite (CALIOP, IASI, OMPS), in situ aerosol counting (LOAC OPC) and lidar observations, and the MIMOSA advection model. The Calbuco aerosol plume reached the Indian Ocean 1 week after the eruption. Over the Reunion Island site (21° S, 55.5° E), the aerosol signal was unambiguously enhanced in comparison with background conditions, with a volcanic aerosol layer extending from 18 to 21 km during the May–July period. All the data reveal an increase by a factor of  ∼  2 in the SAOD (stratospheric aerosol optical depth) with respect to values observed before the eruption. The aerosol mass e-folding time is approximately 90 days, which is rather close to the value ( ∼  80 days) reported for the Sarychev eruption. Microphysical measurements obtained before, during, and after the eruption reflecting the impact of the Calbuco eruption on the lower stratospheric aerosol content have been analyzed over the Reunion Island site. During the passage of the plume, the volcanic aerosol was characterized by an effective radius of 0.16 ± 0.02 µm with a unimodal size distribution for particles above 0.2 µm in diameter. Particle concentrations for sizes larger than 1 µm are too low to be properly detected by the LOAC OPC. The aerosol number concentration was  ∼  20 times higher that observed before and 1 year after the eruption. According to OMPS and lidar observations, a tendency toward conditions before the eruption was observed by April 2016. The volcanic aerosol plume is advected eastward in the Southern Hemisphere and its latitudinal extent is clearly bounded by the subtropical barrier and the polar vortex. The transient behavior of the aerosol layers observed above Reunion Island between May and July 2015 reflects an inhomogeneous spatio-temporal distribution of the plume, which is controlled by the localization of these dynamical barriers.

Published: December 2017

AbstractReproduction and post-metamorphic growth of the American toad (Anaxyrus americanus) were examined in specimens from agricultural fields in south central Pennsylvania. Males were most fertile during spring and early summer. Females were gravid from April to June and in October prior to brumation. Clutch and body size relationships were indicative of a K strategy, perhaps reflecting a population at carrying capacity. Sexual maturity was reached at postmetamorphic ages of approximately two years in males (min = 56.7 mm SVL) and three years in females (min = 68.9 mm SVL). Later-season metamorphoslings of both sexes would not have bred for the first time until nearly one year later. Mean adult body size was smaller in males (mean = 69.4 mm SVL) than in females (mean = 81.5 mm SVL). Life history traits examined in this study reflect responses of both northern and southern populations and quantify effects of site-specific conditions on reproductive relationships.
Selected life history traits of the eastern red-backed salamander, Plethodon cinereus (Green), at a suburban residence in south central Pennsylvania
Authors: Meshaka Walter E. , Wright Danielle 
Published: December 2017

Abstract
Museum specimens of the red-backed salamander, Plethodon cinereus (Green), from a single suburban site in south central Pennsylvania were examined for patterns in life history traits at the latitude and habitat of the population. Seasonal activity was bimodal (April–November). Mating could occur during fall–spring, and 75.9% of all females produced eggs each year. Clutch size (mean = 8.7 eggs) covaried with female body size. Young appeared in the fall, and sexual maturity could be reached just after their second year of life. The frequency of unstriped individuals corroborated the association of this phenotype with warmer climates. The higher incidence of broken/regenerated tails among males and juveniles was suggestive of a lower susceptibility of females to inefficient predators. Overall, life history traits of this population were similar to those of southern populations. In turn, global climate change can be expected to maintain those trends, and even more so in urban heat islands.
Expansion of the invasive Round Goby (Neogobius melanostomus) into Allegheny River tributaries: LeBoeuf and French Creeks in Pennsylvania

Published: December 2017

AbstractThe Round Goby (Neogobius melanostomus) is an invasive fish species currently found in all five of the Laurentian Great Lakes of the United States. Round gobies have previously been restricted to the Lake Erie watershed of Pennsylvania, however, in fall of 2014, they were discovered in portions of the upper Allegheny River watershed, specifically Lake LeBoeuf and LeBoeuf Creek. This introduction was likely via bait bucket transfer. This paper confirms additional records of Round Gobies, including age zero fish and males in breeding colors, in LeBoeuf Creek as well as in the main stem of French Creek, tributaries to the Allegheny River.
Transferrin and Lactoferrin – Human Iron Sources for Enterococci
Authors: LISIECKI PAWEŁ 
Published: December 2017

Abstract
To overcome limitations in iron acquisition, enterococci have evolved a number of mechanisms to scavenge iron from the host iron-binding proteins – transferrin (TR) and lactoferrin (LF). The aim of this study was to demonstrate the mechanisms by which enterococci utilize human TR and LF bound iron. The study included two strains of Enterococcus faecalis grown in iron-deficient and iron-excess media respectively. The binding activity of both proteins was monitored using proteins labelled with 125I. The uptake of iron by enterococci was determined using 59Fe labelled proteins. Reduction of iron bound to TR and LF was assayed with ferrozine. The proteolytic cleavage of TR and LF was visualized by SDS-polyacrylamide gel electrophoresis. The siderophore activity was measured with chrome azurol S. The study revealed that enterococci use several ways to acquire iron from TR and LF, such as iron chelating siderophores, iron reduction – facilitated iron release, protein degradation – promoted iron release, and receptor mediated capture of the iron-host protein complexes. The broad spectrum of iron acquisition mechanisms used by enterococci may play a significant role in the colonization of the human body and the resulting pathogenicity.

OBJECTIVE To evaluate the safety and efficacy of vasopressin for the treatment of hypotension in patients admitted to neonatal intensive care units (NICUs).
METHODS Vasopressin use in 69 infants admitted to our NICU between 2011 and 2014 was examined. Data evaluated included demographics; serum creatinine, sodium, and lactate concentrations; urine output; and systolic, diastolic, and mean blood pressures (BPs). Parameters prior to vasopressin use were compared to those at maximum dose.
RESULTS Vasopressin use was associated with increased urine output (p &lt; 0.05), and increased systolic (p &lt; 0.0005), diastolic (p &lt; 0.01), and mean (p &lt; 0.001) BP. There were no differences in sodium or lactate concentrations before vs during infusion; vasopressin use was not associated with hyponatremia (sodium &lt; 130 mEq/L) at the maximum dose.
CONCLUSIONS Vasopressin for the treatment of neonatal hypotension appears safe and was efficacious in raising BP. These data suggest that vasopressin could be considered a viable option in the treatment regimen in hypotensive infants in the NICU.
Om <em>så</em> og <em>der</em> som genoptagere for ekstraponerede tid og stedsadverbialer
Authors: Christensen Sune Just 
Published: December 2017

The adverbs så and der are both able to represent left dislocated adverbials denoting time. But the Grammatik over det Danske Sprog (GDS) and Ordbog over det Danske Sprog (ODS) both describe how så as opposed to der is not able to represent left dislocated adverbials denoting space. This paper therefore explores in both speech (5,5 hours) and written text (6 million words) the actual distribution of the adverb så and der as representatives for left dislocated adverbials denoting space. The results show that the construction where så represents left dislocated adverbials denoting space is not as infrequent as GDS and ODS prescribes. However alternative analyses of the constructions found in the study may enable a different view at the result.

A qualitative exploration of chiropractic and physiotherapy teachers' experiences and conceptualizations of the educational environment
Authors: Palmgren Per J. , Liljedahl Matilda , Lindquist Ingrid , Laksov Klara Bolander 
Published: December 2017

Objective:
There has been increasing scholarly interest in the role of environments in health care professional education, and the value of these has been widely acknowledged as an influential factor in educational quality. However, little is known about how teachers experience the environment, and there is a recognizable absence of a perspective from chiropractic and physiotherapy faculties. The aim of this study was to explore and contrast chiropractic and physiotherapy teachers' experiences and conceptualizations of the meaning of the educational environment.

Methods:
In this qualitative study, we performed semistructured interviews with 14 teachers, purposefully selected to obtain richness, variation, and breadth in the data. The data were analyzed using inductive qualitative content analysis.

Results:
The most noteworthy findings were, first, that chiropractic teachers experienced the meaning of the environment as motivating a vocational practice and modeling ideal, supporting and managing stressed students, and including students in the community of chiropractors. Physiotherapy teachers experienced the meaning of the environment as putting the pedagogical vision into practice, balancing students' expectations, and providing the prerequisites to grow within the profession. Second, both groups of teachers held common conceptualizations of the constituents of the environment as physical, organizational, relational, communicational, and pedagogical; however, they attached different connotations to these dimensions.

Conclusion:
The findings conveyed a variance in the experience of the meaning of the educational environment that can be attributed to contextual and cultural differences.
