Published: March 2017

A tlu:ee-component aeromagnetic survey of British Columbia and the northeastern Pacifie Ocean was carried out in early 1969. The survey data are in the form of averages over 30 seconds of time, or roughly 3.5 km of flight track. The International Geomagnetic
Reference Field (IGRF) was removed from these data, and the resulting residuals plotted as profiles. A 3rd-degree polynomial was fitted to the survey data by least-squares to determine how well the IGRF represents the average regional field over the survey area. The polynomial was also used to
obtain vector residuals, which require a residual mean close to zero. Lines of zero gradient in the component parallel to the flight tracks are also given.
The Dominion Observatory seismic station at Resolute Bay, Northwest Territories
Authors: Bremner P C
Published: March 2017

The Dominion Observatory has installed a seismograph station at Resolute Bay, Cornwallis Island, latitude 74°41'N., longitude 94°54'W. The need for such a station in the Canadian Arctic has been recognized for many years. The establishment of a joint
weather station at Resolute Bay offered an opportunity for the installation. A preliminary survey of the terrain indicated that the only outcrop of bedrock was situated at a distance of 1,400 feet from the settlement. At a conference held in Ottawa it was decided that electromagnetic instruments
should be used, the detectors to be on the rock outcrop, the recording unit close to the weather station. Field tests carried out at Ottawa throughout a winter season demonstrated the feasibility of this plan.
The station was installed during the summer of 1950. The seismometers were placed on concrete piers and enclosed in a heated, insulated shelter that was subsequently buried with gravel to provide an effective vault. The recording unit was housed in a double-walled, prefabricated building especially
designed for the purpose. Principal source of heat is an oil-fired space heater, but close control is made possible by the additional use of thermostats and electric heaters.
The station is equipped with Sprengnether long-period horizontal seismometers and a Sprengnether short-period vertical instrument. Records are read daily and the data are sent through Ottawa to the United States Coast and Geodetic Survey for use in epicentral determinations.
The paper outlines research investigations undertaken during the first year's operation. The first, a study of near earthquakes, shows that the eastern Arctic islands do not have frequent tremors. The second investigation attempts to associate spurious seismic disturbances with the movement of sea
ice by making a careful study of the tide. A third undertaking was the successful operation of a short-period vertical seismometer on a base consisting of steel pipes driven into the frozen ground. It was established that this frozen medium could be used for transmitting seismic radiation to the
detector if bedrock was not available. Finally, the occurrence of microseismic storms is discussed in relation to atmospheric disturbances.
A seismic survey in the Canadian Shield, II: Refraction studies based on timed blasts
Authors: Urli M , Thiffault N , Chalifour D
Published: March 2017

During the rock burst studies described in Part I of this series, blasts timed at their source were recorded at one or more of the stations of the profile.
One group of blasts, at La Cave and at Rolphton, were timed automatically by the stations maintained at those points. These blasts frequently recorded at the other station of the pair, and sometimes at Ottawa. Timing and location were not as precise as in other sections of this work, but it was
possible to determine mean velocities for P1 and S1 of 6.29 ± 0.04 km/sec. and 3.44 ± 0.03 km/sec. respectively. The uncertainties listed are Probable Errors of the means.
A second group of blasts, occurring at, La Cave and at Temiskaming, were precisely located and were timed with the greatest possible accuracy. They were recorded at stations lying northwestward toward Kirkland Lake, and the series thus provided a reverse profile. P1 and S1 velocities obtained, with
probable errors, were 6.19 ± 0.07 km/sec. and 3.54 ± 0.07 km / sec. A very strong phase, both in the P and S group, suggested the existence of a second layer, but this interpretation proved to be inconsistent with the evidence of other secondary arrivals.
The final group of blasts provided data on the variation of velocity with rock type. The source was near Sudbury and as the blasts were recorded at eight different stations of the rockburst profile a variation of 47° of azimuth was obtained. This provided many different sections across the
Huronian basin. Mean velocities, and their Probable Errors, for P1 and S1 were 6.189 ± 0.023 and 3.551 ± 0.007 km/sec.
The mean for all determinations, including that made with the aid of rockbursts, together with the Probable Error of the mean, proved to be: for P1 6.234 ± 0.012 km/sec., and for S1 3.544 ± 0.011 km/sec. Secondary arrivals, in general, satisfied the single-layer travel time curves
developed for the rockburst profile, although in this case also there were variations from the curves such as might have been due to variations in rock type and variations in crustal thickness.
Diamond drilling in permafrost at Resolute Bay, Northwest Territories
Authors: Bremner P C
Published: March 2017

In the summer of 1948 a number of high-resistance ceramic thermometers were placed in shallow holes drilled in the permanently frozen ground at Resolute Bay (latitude 74° 41' N, longitude 94° 54' W). During the next year the temperature of the soil was
measured daily by Department of Transport officers. The interest engendered by this work led to the suggestion that an attempt be made to drill deep holes and to place temperature-measuring elements at regular intervals to a depth of 1,000 feet. This project was carried out during the four summers
of 1950-53, its object being to drill the holes and install thermometers in them. The reading of the thermometers, the determination of temperatures at various levels and the analysis of the results in terms of heat flow from the earth was to be undertaken by the Department of Transport in
cooperation with Professor A. D. Misener at the University of Western Ontario.
The program was carried out under great difficulties. Because of transportation problems a relatively light drill was used and because of the low temperature of the ground the drilling water often froze in the hole and seized the rods, necessitating the use of hot water heated to an initial
temperature of 190°F. Even this was not sufficient at depths in excess of 600 feet, for the water had cooled almost to the freezing point before it returned to the surface. The work was hampered by caving formations which could not be cased off because of the small size (li inches) of the hole
being drilled. Due to all these difficulties it was necessary to be content with a maximum depth of 650 feet.
Although the original aim of the work was to drill at least one hole of 1,000 feet, the object of determining the temperature gradient at Resolute Bay was almost as well served by the 10 holes successfully completed from 5 to 650 feet in depth, and equipped with temperature elements at 5-foot
intervals to 70 feet, at 10-foot intervals thence to 100 feet and at 50-foot intervals to the maximum of 650 feet.
Cores were taken at all depths to 100 feet and at approximately 50-foot intervals to 650 feet. Some of these cores have been submitted to the Geological Survey of Canada for examination, while the thermal properties of others are being studied at the University of Western Ontario in connection with
the general analysis of the project.
On certain characteristics of irregular magnetic activity observed at Canadian magnetic observatories during 1960
Authors: Aoki W , Archambault R , Bérubé J , Lamoureux Y , Fukuda M , Yamada A
Published: March 2017

Hourly range data in three orthogonal components for the year 1960 are summarized for the Canadian magnetic observatories at Victoria Meanook, Churchill, Baker Lake and Resolute Bay. The times of maxima of the two major patterns of high-latitude corpuscular
precipitation are clearly defined for these locations with one year's data. However the third pattern of disturbance ( the afternoon maximum of disturbance in the auroral zone) postulated by Russian workers is found to be very weak and scarcely identifiable in the average data for one year. It
appears most clearly in the data for disturbed days but the records from one year are then insufficient to remove ail the random peaks. This statistical weakness of the third peak is in agreement with the theory of Axford and Hines (1961). The diurnal plots for different components are similar at
high latitudes, whereas the latitudinal variation of the mean levels of activity for each component differ significantly. Part of this difference can be attributed to varying contributions from induction, and reasonable approximate estimates of the magnitude of the induced terms can be made assuming
a random source model.
Canadian west coast earthquakes, 1953
Authors: Fortin M , Sattler D , Schneider R
Published: March 2017

In 1951 the Dominion Observatory began a program of studying the earthquakes of southwestern British Columbia. The present paper lists 150 earthquakes recorded during 1953; this brings to 443 the number of tremors recorded since the inception of the program in
August, 1951. The new epicentres are tabulated and plotted on a map of southwestern British Columbia. A detailed map of south Vancouver Island shows all the epicentres recorded in this area throughout the program.
The paper also gives the details of the newly built and newly equipped Victoria station.
The gravity anomaly field in northern Manitoba and northeastern Saskatchewan
Authors: Spillebout F , Stoyanov S R , Zelyak O , Stryker J M , Kovalenko A
Published: March 2017

About 4100 new gravity stations were established in 1965 in northern Manitoba and northeastern Saskatchewan by the Dominion Observatory. The survey results are presented as nine Bouguer anomaly maps at a scale of 1: 500, 000. The local Bouguer anomalies are
adequately explained by near-surface Precambrian geological structures using density relations obtained from measurements of rock samples collected in the area. The Bouguer anomalies show a correlation with the degree of granitization; minimum values occur where the granitic rocks appear to be
intrusive. Sedimentary and volcanic sequences are characteristically defined by relatively positive anomalies. Areas of dense granulite facies rocks are also outlined by positive anomalies. lnterpretation of the gravity data is concentrated on the anomalous area traversed by the boundary between the
Churchill and Superior structural provinces of the Canadian Shield. In this region the Pikwitonei subprovince of the Superior Province, an Archaean craton of granulites underlies the Nelson River gravity high. The northwestern boundary of the craton forms the boundary between the Churchill and
Superior provinces and is marked by a steep gravity gradient. Abrupt changes in lithology, density, metamorphic facies and age occur along this boundary.
Gravity measurements in the Sudbury area
Authors: Candanedo J A , Vallianos C , Delcroix B , Date J , Saberi Derakhtenjani, A , Morovat N , John C , Athienitis A K
Published: March 2017

A total of 2, 302 gravity stations established in the Sudbury area (N.T. S. map sheet 41 I) in the period 1945-1969, was used to compile the Bouguer gravity anomaly map (scale 1:250, 000) with 2 mgal contour interval. Most of the area is characterized by a
relatively positive regional gravity anomaly which in its western part includes the Sudbury structure; it may reflect the distribution of gabbroanorthositic rocks within the crust. Regional gravity lows appear to be related to large bodies of granite, such as the Cartier granite and the Killarney
granite , or to granitegneisses of the Grenville Province. Many local gravity anomalies correlate well with the geology but the Sudbury structure itself cannot be related to a simple gravity anomaly.

Authors: Rosato A , Sibilio S , Guarino F , El Youssef, M , Entchev E , Maffei L
Published: March 2017

The geomagnetic components D, H, Z, and the total intensity F were measured at 4.6 km to 6.2 km altitude along flight lines traversing British Columbia and extending 1,400 km westward over the Pacifie. TI1e determination of systematic errors, mainly due to
aircraft magnetic fields, is described. The corrected data, reduced to sea level and averaged over five-minute (~ 35 km) intervals, are listed. Further smoothing was applied to produce contoured charts of D, H, Z, and the Z anomaly field. Sorne features of the Z anomaly chart are discussed. One
anomaly, prominent over a large area in northeastern British Columbia is fitted by models and compared with Precambrian Shield anomalies of similar scale reported by others. IGRF residuals derived from the five-minute averages are shown as profiles in D, H, Z, and F. The regional field, in the form
of a 3rd-degree polynomial, is compared with IGRF.

Discriminación percibida, afrontamiento y salud mental en migrantes peruanos en Santiago de Chile
Authors: Lahoz i Ubach Sonia , Forns i Santacana Maria
Published: March 2017

El paradigma transaccional del estrés conceptualiza la discriminación percibida como un estresor que puede tener consecuencias negativas para la salud mental y que supone el desarrollo de estrategias para hacerles frente. Este estudio examina la discriminación percibida por la población migrante peruana asentada en Santiago de Chile, tanto grupal como personal, y su relación con las estrategias de afrontamiento y con la salud mental. A través de un muestreo de bola de nieve participaron 355 inmigrantes peruanos de entre 18 y 58 años residentes en Santiago, quienes respondieron a una batería de tests sobre discriminación personal y grupal percibida; respuestas de afrontamiento y sintomatología clínica. Los resultados muestran una mayor percepción de discriminación grupal que personal. Las personas que se sienten discriminadas utilizan en mayor medida estrategias de evitación cognitiva, las cuales no muestran relación con sintomatología. Se concluye que el uso de estas estrategias podría tener un rol protector ante los efectos de la discriminación personal percibida.
Jovens estudantes e seus professores: Interação social e currículo dialógico
Authors: Vasconcelos Ivar César Oliveira de , Gomes Candido Alberto da Costa
Published: March 2017

As mudanças da universidade têm levado a certa frustração quando o professor não consegue atender às exigências por informações atualizadas, ainda mais se este jáse conscientizou de que educar não ésóinformar, mas formar. Então, torna-se imperativa a articulação entre conteúdos e destes com valores. Por que tem predominado o currículo que prioriza aspectos informativos da educação, portanto, menos dialógico? Nesta perspectiva, investiga-se a interação entre experiências sociaisconstruídas por estudantes e professores, visando a compreender como concretizar, cada vez mais, o currículo dialógico. Um estudo de casos múltiplos revelou o hábito de culpar o outro pelo insucesso acadêmico, a negação da capacidade de crítica dos sujeitos e a tendência a cultivar relações autoritárias.
Valoración del alumnado de primaria sobre convivencia escolar: El valor de la red de iguales
Authors: Còrdoba Alcaide Francisco , Del Rey Alamillo Rosario , Casas Bolaños José Antonio , Ortega Ruiz Rosario
Published: March 2017

Este estudio buscó conocer los elementos más relevantes que los escolares de tercer ciclo de primaria de Andalucía consideran cuando perciben y enjuician la convivencia escolar, así como las dimensiones que tienen valor predictivo sobre su valoración de la convivencia escolar. Bajo un diseño transversal con una muestra representativa de la población de Andalucía, España, se encuestó a 1265 estudiantes (47.7% niñas). Los resultados descriptivos indican que la convivencia escolar se caracteriza por buenos niveles de calidad en las relaciones interpersonales y bajos niveles de dificultades que afectan a las mismas. Los resultados de la regresión lineal múltiple sugieren que, entre los elementos con valor predictivo a la hora de que un/a niño/a valore la convivencia en su escuela como positiva, destaca la red de iguales, es decir, el sistema de relaciones entre pares. A pesar de encontrar diferencias en función del sexo y del curso del alumnado en los modelos de regresión, la percepción positiva de la red de iguales mantuvo un valor predictivo sobre la valoración de una buena convivencia escolar.
Bypass del cuerpo simbólico: Algunas consideraciones psicológicas de las cirugías bariátricas en obesidad mórbida
Authors: Bilbao Ramirez Rodrigo
Published: March 2017

Este artículo revisa el tratamiento de la obesidad a través de intervenciones bariatricas, localizando algunas consecuencias clínicas. Ofrece una nueva lectura desde el psicoanálisis, tomando en cuenta una comprensión del cuerpo desde los tres registros Real-Simbólico-Imaginario de Jacques Lacan, con el cual se analiza el modelo actual de tratamiento.  Se reconoce por esta vía la ausencia del cuerpo simbólico en el modelo de intervención y la necesidad de reintroducirlo en la escena médica y psicológica. Se muestra cómo el olvido de esta dimensión puede estar a la base del malestar psicológico y fracasos post operatorio.  Por último, se orienta de modo transversal a reconocer la multidimensionalidad del cuerpo que ofrece las tres dimensiones interrelacionadas, como un esfuerzo de superar la división cartesiana mente-cuerpo.
Reconstrucción de soportes sociales en mujeres urbanos populares post viudez: Una mirada a los cuidados
Authors: Del Pozo Marisol Tatiana , Thumala Dockendorff Daniela
Published: March 2017

La creciente feminización de la vejez, junto al carácter de género del envejecimiento, sitúan la viudez de mujeres mayores como un momento privilegiado para observar el quiebre en la organización de los cuidados. Se realizó un estudio cualitativo en mujeres adultas mayores viudas, de sectores populares urbanos de la ciudad de Santiago, bjetivo fue identificar y describir la existencia de patrones de género y de  socialización, en el modo en que reconstruyeron sus relaciones de soporte social.  Los hallazgos más relevantes se refieren al  impacto del tipo de relación de pareja, en términos de expectativas de género, en las atribuciones de significado frente a las pérdidas asociadas a la viudez y el modo como estas atribuciones impactan la reconstrucción de soportes.  Estos resultados permiten sostener que la construcción social de género y la socialización configuran las distintas viudeces expresadas por las mujeres.  El aporte de este estudio es la aproximación desde la perspectiva de los cuidados y sus determinantes de género a la comprensión de la viudez femenina en la adultez mayor.

Published: March 2017

El envejecimiento progresivo mundial, junto a otros factores, han llevado a los sistemas de pensiones, sus reformas y las desigualdades de género a la discusión internacional. En este contexto se inserta el debate chileno en torno a las Administradoras de Fondos de Pensiones. Este artículo tiene como propósito conocer las vivencias y percepciones de mujeres jubiladas por el sistema de pensiones privado en Chile respecto a los montos de sus pensiones actuales. Para ello se entrevistaron 16 mujeres jubiladas y se utilizó Análisis de Contenido Cualitativo para el procesamiento de los datos. Los resultados dan cuenta de tres categorías: la percepción de estafa y el arrepentimiento en el traspaso a la AFP; discriminación de género en el ámbito laboral que impacta en la jubilación; y empobrecimiento y sufrimiento en la vida cotidiana. Se concluye que las vivencias subjetivas de las mujeres están marcadas por el sufrimiento, desamparo y el pesimismo, lo que hace difícil aspirar a una sociedad con equidad de género si el sistema de pensiones se configura como discriminatorio y poco solidario.

Published: March 2017

Cuidar a un familiar dependiente es una actividad cada vez más necesaria debido al aumento de la esperanza de vida, pero a la vez más conflictiva y dependiente de las características legislativas y cambios sociales ocurridos en cada país, como la incorporación de la mujer al mercado laboral. Las cuidadoras familiares constituyen una población especialmente vulnerable cuya salud física y psicológica está en riesgo y que requiere de especial atención. Por ello, en este trabajo se analizan los estudios empíricos que en los últimos cinco años se han realizado en cuidadoras españolas. Se destacan las características de esta población, los instrumentos que se han empleado para estudiarlas y las conclusiones a las que en los diferentes estudios se han llegado
Infancia, palabra y silencio: Aproximación desde una perspectiva constructivista
Authors: Miranda Miranda Jenniffer , Cortés Espinoza Catalina , Vera Pavez Juan Ignacio
Published: March 2017

Este artículo describe la investigación realizada con el objetivo de reducir la victimización secundaria en la población infantil, particularmente aquella asociada al maltrato y las agresiones sexuales. Se presenta una revisión teórica del silencio como concepción histórica de la infancia y de la participación infantil, y se expone la comprensión de la construcción de significados desde la perspectiva constructivista. Como una aproximación inicial y utilizando una metodología cualitativa, se desarrollaron Talleres de Filosofía con 35 niños y niñas de cuarto año de la Enseñanza Básica de Santiago, Chile. La producción de diálogos fue sometida a análisis de contenido. Los resultados indican que los/as niños/as entienden el silencio como estrategia de escape a dificultades e inexpresión de emociones negativas. La palabra es la expresión de felicidad y cooperación mutua, pero al mismo tiempo, la significan como fuente de dolor e imposición de otros. En conclusión, es necesario generar nuevos modos de relación entre el mundo infantil y el adulto, con el foco en desarrollar nuevos conocimientos sobre las percepciones y expectativas de los/as propios/as niños/as, y en sus necesidades.
Abordaje de la intervención sociocomunitaria en programas de rehabilitación psicosocial: Un estudio de caso en dos dispositivos del sur de Chile.
Authors: Avello Saez Daniela , Román Morales Alberto , Zambrano Constanzo Alba
Published: March 2017

Esta investigación caracteriza las prácticas en rehabilitación psicosocial de profesionales de dos dispositivos, profundizando en el análisis de la dimensión sociocomunitaria. Los datos fueron producidos a partir de entrevistas grupales en donde participaron trece profesionales de las regiones del Biobío y La Araucanía. Los datos fueron examinados a través de análisis de contenido en su aproximación dirigida. Los resultados reportan que a pesar de que los equipos valoran la necesidad de incluir en las intervenciones aspectos contextuales como la comunidad y las redes institucionales, en la práctica priman estrategias para el desarrollo de competencias individuales en las personas atendidas. Paradojalmente, la comunidad aparece para los equipos como una amenaza al trabajo de rehabilitación que realizan puesto que en ella se encuentran los principales factores de riesgo de sus usuarios y claras condiciones que restringen la inclusión de esta población. Se aprecian tensiones entre los modelos institucionales que incluyen en sus lineamientos programáticos la dimensión social y comunitaria, y el plano operativo administrativo que en la práctica lo obstaculiza.
Autoagresión y auto concepto en adolescentes violentadas sexualmente: una mirada descriptiva
Authors: Vallejo Samudio Álvaro , Granados Brenda E.
Published: March 2017

Este artículo tiene como objetivo analizar de forma descriptiva, las expresiones verbales de 11 adolescentes violentadas sexualmente, con relación a la forma como se auto agreden y el auto concepto que construyen de sí mismas. Ellas participaron en un proceso psicoterapéutico de tres meses, a razón de dos sesiones semanales y de hora y media de duración. Se utilizó una metodología mixta de origen cuantitativo y cualitativo, se analizaron fundamentalmente dos categorías, la agresión corporal a sí mismas y la agresión psicológica a sí mismas. Para ello, se tomaron 195 fragmentos de las 23 sesiones en las que participaron. Los resultados evidencian que la agresión psicológica es mayor que la agresión corporal a sí mismas, que no existe correlación lineal entre estas dos categorías y que la forma como dirigen la agresión corporal hacia sí mismas,  va desde el ataque al propio cuerpo a través de sustancias psicoactivas hasta intentos serios de suicidio. La agresión psicológica a sí mismas, se caracteriza fundamentalmente en el daño al vínculo afectivo y al auto concepto negativo que construyen de sí mismas.
Bayesian inverse modeling and source location of an unintended I-131 release in Europe in the fall of 2011

Published: March 2017

Abstract. In the fall of 2011, iodine-131 (I-131) was detected at several radionuclide monitoring stations in Central Europe. After investigation, the International Atomic Energy Agency (IAEA) was informed by Hungarian authorities that I-131 was released from the Institute of Isotopes Ltd in Budapest, Hungary. It was reported that a total activity of 342 GBq of I-131 was emitted between September 8 and November 16, 2011. In this study, we use the ambient concentration measurements of I-131 to determine the location of the release as well as its magnitude and temporal variation. Although the location of the release became eventually known, its temporal variation is still uncertain and only partial information is available. For our source reconstruction, we use no prior knowledge. Instead, we estimate the source location and emission variation using only the available I-131 measurements. Subsequently, we use the information about the source term for validation of our results. For the source determination, we first perform backward runs of atmospheric transport models and obtain source-receptor-sensitivity (SRS) matrices for each grid cell of our study domain. We use two dispersion models, Flexpart and Hysplit, driven with meteorological analysis data from the global forecast system (GFS) weather forecast model. Second, we use a recently developed inverse method, least-squares with adaptive prior covariance (LS-APC), to determine the I-131 emissions and their temporal variation from the measurements and computed SRS matrices. For each grid cell of our simulation domain, we evaluate the probability that the release was generated in that cell using Bayesian model selection. The model selection procedure also provides information about the most suitable dispersion model for the source term reconstruction. Third, we select the most probable location of the release with its associated source term and perform forward calculation to study the consequences of the iodine release. Results of these procedures are compared with the known release location and reported information about its time variation. We find that our algorithm could successfully locate the actual release site. The estimated release period is also in agreement with the values reported by IAEA, while our estimate for the total released activity (490 GBq) is higher than the reported one (342 GBq). Nevertheless, even using our larger source term, dose amounts were very low and never exceeded regulatory limits.
Tagged tracer simulations of black carbon in the Arctic: Transport, source contributions, and budget

Published: March 2017

Abstract. We implemented a tagged tracer method of black carbon (BC) into a global chemistry-transport model GEOS-Chem, examined the pathways and efficiency of long-range transport from a variety of anthropogenic and biomass burning emission sources to the Arctic, and quantified the source contributions of individual emissions. Firstly, we evaluated the simulated BC by comparing it with observations at the Arctic sites and found that the simulated seasonal variations were improved by implementing an aging parameterization and reducing the wet scavenging rate by ice clouds. For tagging BC, we added BC tracers distinguished by source types (anthropogenic and biomass burning) and regions; the global domain was divided into 16 and 27 regions for anthropogenic and biomass burning emissions, respectively. Our simulations showed that BC emitted from Europe and Russia was transported to the Arctic mainly in the lower troposphere during winter and spring. In particular, BC transported from Russia was widely spread over the Arctic in winter and spring, leading to a dominant contribution of 62 % to the Arctic BC near the surface as the annual mean. In contrast, BC emitted from East Asia was found to be transported in the middle troposphere into the Arctic mainly over the Okhotsk Sea and East Siberia during winter and spring. We identified an important window area, which allowed a strong incoming of East Asian BC to the Arctic (130°–180° E and 3–8 km altitude at 66° N). The model demonstrated that the contribution from East Asia to the Arctic had a maximum at about 5 km altitude due to uplifting during the long-range transport in early spring. The efficiency of BC transport from East Asia to the Arctic was smaller than that from other large source regions such as Europe, Russia and North America. However, the East Asian contribution was most important for BC in the middle troposphere (41 %) and BC burden over the Arctic (27 %) because of the large emissions from this region. These results suggested that the main sources of the Arctic BC differed with altitude. The contribution of all the anthropogenic sources to Arctic BC concentrations near the surface was dominant (90 %) on an annual basis. The contributions of biomass burning in boreal regions (Siberia, Alaska and Canada) to the annual total BC deposition onto the Arctic were estimated to be 12–15 %, which became the maximum during summer.
How to make them walk the talk: governing the implementation of energy and climate policies into local practices
Authors: Mattissek Annika , Sturm Cindy
Published: March 2017

Abstract. Urban policy mobility has become a lively field of research in recent years. One important argument has been that policies do not travel from place to place unmodified, but are transformed in the process of their implementation. Drawing on a research project on adaptations of climate protection policies in German cities we elaborate how discourse studies and work on governmentality can be brought into resonance with the policy mobility debate. We suggest that these theoretical concepts can be used to explain why, despite the growing number of laws and recommendations in this context, local adaptations of climate policies vary significantly between different cities. We argue that the concept of governmentality is particularly well suited to grasping the discrepancies between discursively produced guidelines and actual planning practices and to conceptualising these planning practices as effects of competing and often conflicting technologies of government.
L’effet de la personnalité sur la performance des étudiants universitaires en sciences de l’administration à l’examen écrit, au test à choix multiple et aux travaux pratiques
Authors: Lakhal Sawsen , Frenette Éric , Sevigny Serge
Published: March 2017

Plusieurs programmes universitaires en sciences de l’administration au Canada ont implanté des réformes majeures, suite aux demandes des organismes d’agrément tels que l’Association to Advance Collegiate Schools of Business (AACSB). Conséquemment, de plus en plus de méthodes d’évaluation des apprentissages sont utilisées. Toutefois, l’introduction de ces méthodes dans les programmes d’études pourrait engendrer des biais aux résultats de l’évaluation des apprentissages. L’étude des facteurs pouvant avoir un effet sur la performance des étudiants aux différentes méthodes d’évaluation devient pertinente dans ce contexte. Ainsi, l’objectif de cette étude consiste à vérifier si la personnalité telle que définie par le modèle des cinq facteurs influence la performance à l’examen écrit, au test à choix multiples et aux travaux pratiques. Deux variables contrôle, le genre et l’âge, sont inclus dans les analyses. Un échantillon de 378 étudiants inscrits à un cours de premier cycle universitaire en sciences de l’administration a répondu à un questionnaire en ligne. Les résultats des analyses des régressions linéaires multiples indiquent que ce ne sont pas toujours les mêmes facteurs de la personnalité qui sont sollicités d’une méthode d’évaluation à l’autre, indiquant l’existence potentielle de biais à l’évaluation des apprentissages. Ces résultats sont discutés au regard de la littérature plus large dans le domaine et touchant à d’autres programmes d’études universitaires.
In Canada, a number of university programs in business administration have imbedded major reforms, following requests from accreditation bodies such as the Association to Advance Collegiate Schools of Business (AACSB). Consequently, more and more learning assessment methods are used. However, the introduction of these methods in curricula could lead to bias to the results of learning assessment. In this context, it becomes pertinent to study the factors that could affect student performance with the various assessment methods. Thus, the aim of this study is to verify if personality, as defined by the five-factor model, impacts the performance on written exams, multiple-choice exams, and practical exercises. Two control variables, gender and age, are included in the analyses. A sample of 378 students in an undergraduate business administration course responded to an online questionnaire. The results of analyses of multiple linear regressions shows that not always the same personality factors are solicited from one assessment method to the next, which indicates the potential existence of bias to the learning assessment. These results are discussed against the broader literature in the field and in other university programs.

We describe interim results of an ongoing longitudinal pedagogical study investigating the efficacy of the Honours Integrated Science Program (iSci). We describe the pedagogical methods we use to prompt research skill development in a model from instructor-dependence to independent original research. We also describe a tool we use to help students organise their group research during their first attempts. Finally, we discuss students’ perceptions of how well iSci develops their research skills.
Our results show that students are attracted to the iSci program because of the opportunities for research-based learning and skills development. We also found that in-program students value research skill development as a tool for successful completion of their degree and for their future academic or career plans. We conclude that our study methods help identify areas where we can support our students by building their research confidence and, in particular, their time-management skills.
Nous présentons une description des résultats intérimaires d’une étude pédagogique longitudinale qui vise à évaluer l’efficacité du programme spécialisé intégré de sciences (iSci). Nous faisons une description des méthodes pédagogiques que nous utilisons pour déclencher le développement des compétences en recherche au sein d’un modèle qui va de la recherche qui dépend de l’instructeur à la recherche indépendante originale. Nous décrivons également un outil que nous utilisons pour aider les étudiants à organiser leur recherche par groupe au cours de leurs premières tentatives. Pour finir, nous discutons les perceptions des étudiants sur la manière dont le programme iSci développe leurs compétences en recherche.
Nos résultats indiquent que les étudiants sont attirés vers le programme iSci à cause des occasions d’apprentissage basé sur la recherche et de développement des compétences. Nous avons également remarqué que les étudiants inscrits au programme apprécient le développement de compétences en recherche en tant qu’outil qui leur servira à terminer leurs études et à obtenir leur diplôme, ou pour leurs projets de carrière, à l’avenir. En conclusion, nous déclarons que nos méthodes d’études aident à identifier les domaines où nous pouvons soutenir les étudiants en renforçant leur confiance en matière de recherche et, en particulier, leurs compétences en gestion du temps.

It has been argued that for novice students to acquire a full understanding of scientific texts, they also need to pursue a recurrent construction of their comprehension of scientific concepts. The course dossier method has students examine concepts in multiple passes: (a) through reflective writing on text before it is considered in the classroom, (b) in a one-page essay at the end of the week, and (c) through a final essay at the end of the term. Students are encouraged to relate to the text in their reflective writing and critiques in the manner of a hermeneutical circle. Students are further scaffolded in writing their final essay by the use of student reviewers. This study explored how students in a humanities course perceived and accomplished the course dossier method. It was found that students’ understanding of concepts improved as the course progressed.
D’aucuns ont fait valoir qu’afin que les étudiants novices comprennent pleinement les textes scientifiques, ils doivent également poursuivre une construction récurrente de leur compréhension des concepts scientifiques. La méthode qui consiste à tenir un dossier de cours requiert des étudiants qu’ils examinent les concepts en plusieurs passes : (a) par le biais de la rédaction réflective sur le texte avant que celui-ci soit étudié en classe, (b) par un essai d’une page à la fin de la semaine et (c) par un essai final à la fin du trimestre. Les étudiants sont encouragés à mettre le texte en rapport avec leur rédaction réflective et leurs critiques à la manière d’un cercle herméneutique. De plus, les étudiants sont davantage préparés à rédiger leur essai final par l’utilisation d’étudiants réviseurs. Cette étude explore la manière dont les étudiants d’un cours de sciences humaines perçoivent et accomplissent la méthode qui consiste à tenir un dossier de cours. On a découvert qu’au fur et à mesure que le cours a progressé, les étudiants ont davantage compris les concepts.
Evaluating the Implementation and Effectiveness of Reflection Writing

There is ample theoretical justification for incorporating reflection exercises as a tool for preparing students for life beyond university, yet the utility of such exercises needs to be documented if resources are to be devoted to their implementation. This study describes the implementation and evaluates the effectiveness of a reflection exercise that was introduced in an entry-level undergraduate psychology course. Students completed four periodic reflection journals and submitted an essay summarizing their progress as learner at the end of the semester using examples from the journals to support their reflection. Multiple qualitative analysis methods were used to measure the reflective content of the summary essays. The analyses support the effectiveness of the exercise in promoting reflection on the process of learning including strengths, weaknesses, learning strategies, competence, efforts, and emotions. In addition, reviewing the reflective essays provided the instructor with invaluable insight into the students’ experience. We conclude that reflection writing can be incorporated in undergraduate studies to encourage the development of life-long learning skills with reasonable time requirements. Suggestions for modes of implementation as well as future avenues of research are discussed.
Il existe une ample justification théorique à l’incorporation d’exercices de réflexion en tant qu’outils pour préparer les étudiants à la vie après l’université, et pourtant l’utilité de tels exercices a besoin d’être documentée avant de consacrer des ressources à leur mise en oeuvre. Cette étude décrit la mise en oeuvre et évalue l’efficacité d’un exercice de réflexion qui a été présenté dans un cours de premier cycle en psychologie. Les étudiants ont complété quatre journaux de réflexion personnelle au cours du semestre et à la fin du cours, ils ont rédigé un essai dans lequel ils ont résumé leurs progrès en tant qu’apprenants en utilisant des exemples tirés de leurs journaux pour soutenir leur réflexion. Plusieurs méthodes d’analyse qualitative ont été utilisées pour mesurer le contenu réflectif des essais. Les analyses soutiennent l’efficacité de l’exercice pour favoriser la réflexion sur le processus d’apprentissage, y compris les forces, les faiblesses, les stratégies d’apprentissage, la compétence, les efforts et les émotions. De plus, le fait d’avoir examiné les essais de réflexion a fourni à l'instructeur des indications d’une valeur inestimable sur l’expérience des étudiants. Nous concluons que la rédaction réflective peut être incorporée dans les études de premier cycle pour encourager le développement de compétences d’apprentissage qui serviront tout au long de la vie et ce selon des exigences raisonnables quant au temps requis. Des suggestions de divers modes de mise en oeuvre ainsi que d’avenues pour des recherches futures sont également discutées.
ESPAÇOS HÍBRIDOS DA AGRICULTURA FAMILIAR: A PAISAGEM CULTURAL DAS FEIRAS AGROECOLOGICAS DO RECIFE-PE

Published: March 2017

Analisando as feiras agroecologicas da cidade do Recife, sob a ótica da paisagem cultural é possível perceber que existe uma mesclagem de valores estéticos e culturais que são predominantes tanto no meio rural como no urbano. Essa mistura de cultura rural/urbano possibilita o surgimento de processos de hibridização através dos vários aspectos e características do espaço de comercialização dos produtos. Além do mais, a dinâmica e as relações estabelecidas entre os consumidores e agricultores familiares, atribuem um sentido ou valor diferenciado ao espaço de comercialização familiar. Nesse contexto observa-se uma transformação da paisagem local em dias de feira agroecológica em alguns bairros do Recife.
