Palabras Clave

La variabilidad climática es la norma que ha modulado la vida en el planeta. Este trabajo demuestra que las pesquerías y acuicultura costera ecuatorianas no son la excepción, puesto que tales actividades están fuertemente influenciadas por la variabilidad ENSO (El Niño-Oscilación del Sur) y PDO (Oscilación Decadal del Pacífico), planteándose que la señal del cambio climático debe contribuir a esta influencia. Se destaca también que, en el análisis de los efectos de la variabilidad climática sobre los recursos pesqueros, el esfuerzo extractivo también debe ser considerado. Por su parte, la acción actual de la PDO está afectando la señal del cambio climático, encontrándose actualmente en fases opuestas. Se espera que estas señales entren en fase a finales de esta década, y principalmente durante la década de los 20 y consecuentemente se evidencien con mayor fuerza los efectos del Cambio Climático. Palabras Clave: Variabilidad Climática, Cambio Climático, ENSO, PDO, Pesquerías, Ecuador. ABSTRACT Climate variability is the standard that has modulated life in the planet. This work shows that the Ecuadorian  fisheries and aquaculture are not the exception, since such activities are strongly influenced by ENSO variability (El Niño - Southern Oscillation) and PDO (Pacific Decadal Oscillation), considering that the signal of climate change should contribute to this influence. It also emphasizes that in the analysis of the effects of climate variability on the fishing resources, the extractive effort must also be considered. For its part, the current action of the PDO is affecting the signal of climate change, now found on opposite phases. It is hoped that these signals come into phase at the end of this decade, and especially during the decade of the 20’s and more strongly evidencing the effects of climate change. Keywords: Climate variability, climate change, ENSO (El Niño - Southern Oscillation) and PDO  (Pacific Decadal Oscillation); fisheries, Ecuador. Recibido: mayo, 2012Aprobado: agosto, 2012

A considerable photo-current enhancement was found at the Cu/p-Cu2O/rGO-electrolyte interface in a photo-electrochemical cell with compared to that of Cu/p-Cu2O-electrolyte interface. The reason for the photo-current enhancement may be due to the efficient charge separation process provided at Cu/p-Cu2O/rGO-electrolyte interface. Here rGO (reduced graphene oxide) acts as an electron acceptor for the photo-generated charge carriers as it readily accept electrons from the conduction band of p-Cu2O. rGO was synthesized using electro-phoretic deposition (EPD) technique. Fabricated samples were characterized using diffuse reflectance spectra, photo-current action spectra and the time development of the photocurrent of photo-electrochemical cells.

El presente estudio busca comprender bajo un enfoque naturalista cómo en un periodo denominado por autores de las Ciencias Sociales ( Bajoit, 2009; Sandoval, 2010) de “cambio cultural”, emerge el movimiento Hip Hop y su particular forma de expresión en la ciudad de Punta Arenas. La investigación tiene un objetivo central y busca interpretar la relación entre la expresión contracultural y los jóvenes que son parte de tal, como así también sus significados respecto al ser actores del mismo. La investigación pretende identificar, entonces, la lógica de acción actual de los jóvenes y a su vez dilucidar si existe relación o no con la raíz histórica del movimiento Hip Hop, es decir una expresión de disidencia en razón de la estructura social establecida y las contradicciones que afloran de la misma. The following study aims to understand under the naturalist approach how in a period called for authors of the social sciences (Bajoit, 2009; Sandoval, 2010) of “cultural change”, emerges the Hip Hop movement and its particular form of expression in the city of Punta Arenas. The research has a main objective and seeks to interpret the relation between the expression counterculture and the young people that are part of it, likewise the meaning concerning to be actors of it. The research pretends to identify the logic of current action of the youngsters and at the same time elucidate if there is a relation or not with the historical root of the movement “Hip Hop”, i.e. an expression of dissent aiming with the social structure established and the contradictions that came out from itself.

Action Value

Objective Beta thalassaemias are a group of hereditary red cell disorders resulting in a reduced or absent production of the main adult haemoglobin, adult haemoglobin. In England, the NHS Sickle Cell & Thalassaemia Screening Programme recommends reporting newborn beta thalassaemia disease as an incidental finding when detected whilst screening for sickle cell disease. The current action value to initiate further investigations is 1.5% adult haemoglobin, using high-performance liquid chromatography or capillary electrophoresis. We examined the reliability of this action value. Methods A 44-month country-wide prospective study using data from 13 newborn screening laboratories in England. Results There were 81 cases reported with an adult haemoglobin of 1.5% or less at first-line screen, of which nine were lost to follow-up. The six false-positive results were all of 32 weeks’ gestation or less. Of the 66 true-positives, 36 had confirmatory molecular results (11 of these cases also have results from tandem mass spectrometry), 19 had clinical confirmation and 11 had the results of both parents available which were consistent with the screening result. There was one false-negative, a confirmed beta thalassaemia major case with an adult haemoglobin of 1.7%, above the action value at first-line screen but known to be at risk from parental results and therefore referred into clinical care by the laboratory. Conclusions This study demonstrates a positive predictive value of 91.7%, with a specificity of 99.9% and a sensitivity of 98.5%. These results confirm the reliability of the current action value.

Air Photo

With the advent of air photography, many problems of mapping coast lines, such as those caused by surf action and underwater obstructions, were solved, as the vertical air photo shows the exact configuration of the coast and reveals many of the shallow-water obstructions. This paper shows that aerial photographs, obtained at intervals ranging from 2 to 20 years, contain important information on long-term coastal changes, brought about by wave and current action over a period of time. Two examples of such changes, revealed by sequential aerial photography, are given. It is concluded that a program of systematic study of existing photographs and supplementary rephotography would more than justify its cost.

Abstract The tarnished plant bug, Lygus lineolaris (Palisot de Beauvois), is an important pest of cotton in many areas of the southern United States. An experiment was conducted at two locations in Mississippi during 2016 and 2017 to evaluate action thresholds for tarnished plant bug on a novel Bacillus thuringiensis cotton that expresses the Cry51Aa2.834_16 toxin. Treatments included the current action threshold, a 2× threshold, and treatments where insecticides were only applied during the early season (preflower) or only during late season (during flowering) based on the current action thresholds. These were compared to an untreated control and a weekly insecticide use regime that received weekly insecticide sprays. All treatments were imposed on both Bt Cry1Aa2.834_16 cotton and a nontraited cotton. The Bt Cry1Aa2.834_16 trait reduced the number of tarnished plant bugs and injury, and improved yields compared to nontraited cotton. For all spray treatments except the weekly insecticide use regime, yields were greater for the Bt Cry51Aa2.834_16 cotton than the nontraited cotton. In terms of thresholds, Bt Cry1Aa2.834_16 cotton sprayed based on current action thresholds resulted in similar yields to the weekly insecticide use regime of both cotton types. In contrast, the 2× threshold resulted in lower yields than the current threshold for both cotton types. Though thresholds intermediate to the currently recommended action threshold and the 2× threshold were not tested, these data suggest that currently recommended action thresholds appear appropriate for Bt Cry51Aa2.834_16 cotton. These results suggest that this trait will be an important component of current IPM programs in cotton where tarnished plant bug is an important pest.

Teachers use situated knowledge to deal with the complex and diffuse educational contexts they operate in. To be able to take deliberated action, based on the situated knowledge, reflection is necessary during the teacher training. Video cases with common, real world situations are suitable for reflection because of their holistic and diffuse character. Reflection concerns learning experiences with increasing complexity: single-loop (reflecting on a current action), double-loop (reflecting to gain new insights) and triple-loop (reflecting in order to adjust individual identity) learning. The knowledge gained from loop learning is of a situated nature. The current article operationalizes situated knowledge as educational purposes and design patterns; educational purposes determine which course of action (design pattern), is the best option. Using this distinction, we investigate whether the reflection done by fourth-year teachers in training corresponds to what can be expected of a starting expert, namely, reflection on all three levels. The results indicate that three out of four teachers in training can be characterized as starting experts, based on their responses to a video case. They experience learning on all three loop levels, and these experiences contribute to a variety of educational purposes and design patterns. It is the teacher trainers’ challenge to have their students reflects using video cases, so they can use loop-learning to build their situated knowledge. This knowledge will allow them to adequately respond to the complex and diffuse situations in their educational practice.
