Anàlisi de les competències transversals des de la carpeta d'estudiant
Un dels debats més importants en l'àmbit de la pedagogia en l'Educació Superior avui en dia és el generat per les competències transversals. No resulta gaire difícil ubicar les competències específiques a cada una de les assignatures d'una àrea, però, com fer-ho en aquelles competències transversals i que per tant afecten a totes o quasi totes aquestes assignatures? Quina relació tenen les competències transversals amb la transdiciplinarietat i la interdisciplinarietat? Les respostes a aquestes preguntes tindran molt a veure amb que l'alumne futur estigui capacitat per a la societat del canvi i de la mobilitat, i per a creure realment que l'aprenentatge/ensenyament prepara per la vida i la professió, i fa adquirir coneixements i actituds vàlids per quelcom més enllà de la unidimensionalitat d'una disciplina acadèmica. Des de la Unitat de Didàctica de les Arts Plàstiques ens hem preguntem com resoldre aquest problema i establir estratègies per a fer-ho a partir de les "carpetes d'estudiant" com evidència. A partir de la declaració de Bolonya (1999) i del projecte Tuning apareixen dos conjunts de competències diferents, les específiques i les genèriques. L'ANECA (2005)1 va establir una selecció d'aquestes per la seva aplicació en la titulació de Grau per Mestres d'Infantil i Primària de les quals es desprenien unes competències transversals - per altre cantó totalment discutibles- comunes a totes elles: instrumentals, sistèmiques i personals2. Aquestes competències transversals s'ha convertit des de fa temps en un debat molt importat per tots els agent implicats en el canvi pedagògic vers l'EEES: "¿Por qué nos empeñamos en encontrar unas competencias que sean «tranversales» a las disciplinas escolares? Es probable que esta nueva noción aporte una respuesta a un problema muy antiguo: el problema de saber para qué sirve lo que se aprende en la escuela." Bernard Rey (2000) La situació és realment fonamental i te implicacions no sols en l'ensenyament / aprenentatge sinó també en la empleabilitat i el model de vida: els alumnes que surten de les nostres titulacions ( titulacions de mestre) seran formadors i la seva activitat no sols pot consistir en donar habilitats mecàniques, sinó més bé, en ajudar a construir una capacitat de crear sentit al món on es viu i a les vides que es viuen. I en aquesta tasca les competències transversals tenen una funció essencial. Així doncs, hi ha tres treballs a fer, identificar aquest tipus de competències, definir-les i ubicar la seva situació dins del currículum de la titulació a partir de les assignatures que la formen. L'estudi que hem realitzat parteix de les carpetes d'estudiant (portfolis) per a identificar, definir i ubicar aquestes competències transversals
Avaluació de la creativitat en les arts visuals i plàstica
Les àrees de les arts estan caracteritzades per l'ambigüitat i subjectivitat. Així la avaluació i els seus indicadors tenen seriosos problemes d'objectivitat. L'estudi que hem realitzar a l'àrea de Visual i Plàstica de CCEE és proposa obtenir criteris per a l'avaluació de la CREATIVITAT en el marc d'aquestes dificultats

En ciencias de la salud la investigación tiene la característica esencial de que el
sujeto de estudio es la persona. Si las enfermeras son las investigadoras
principales, si participan en equipos o intervienen en alguna investigación, es
imprescindible que adquieran sensibilidad ética, compromiso con las personas y
que aboguen la máxima Kantiana: “la persona siempre es un fin en sí misma y
nunca un medio para otros propósitos”.
El Consejo Internacional de Enfermería (CIE) elaboró las directrices éticas para
la investigación integrando los principios del Informe Belmont y concretándolos
en la profesión enfermera. Ya desde la formación básica se debe introducir a los
alumnos en el debate sobre los problemas éticos de la investigación para que
apliquen los principios éticos en casos concretos y los traduzcan en conductas
profesionales.
El objetivo de este póster es presentar el método utilizado en la asignatura de
Ética y Legislación Profesional del Grado de Enfermería para sensibilizar a los
alumnos sobre el comportamiento ético de los investigadores e introducirlos en
la aplicación de principios éticos básicos en la investigación con personas.
Método:
El método docente utilizado para esta actividad es el debate. Los grupos de
trabajo son de 24 alumnos, en grupos de 6, que analizan diferentes casos
clínicos de conflicto ético en situaciones de investigación. El objetivo es discutir
la aplicación de los principios éticos del Informe Belmont y de las Directrices para
la Investigación Enfermera publicadas por el CIE..
Three Millennia of Climatic, Ecological, and Cultural Change on Easter Island: An Integrative Overview
Eastern Island (Rapa Nui) is famous for the legacy of an extinct civilization symbolized by the megalithic statues called moai. Several enigmas regarding the colonization of the island its deforestation and a presumed cultural collapse of the ancient civilization still remain elusive. According to the prevailing view, the first settlers arrived between AD 800 and AD 1200 from east Polynesia and overexploited the island's natural resources causing an ecological catastrophe leading to a cultural collapse (Flenley and Bahn, 2003 ). The main evidence for this theory was the abrupt replacement of palm pollen by grass pollen in the sediments of the island's lakes and mires (Raraku, Kao, and Aroi), which was interpreted in terms of a thorough deforestation between approximately AD 1200 and AD 1400/1600 (Flenley and King, 1984; Flenley et al., 1991; Mann et al., 2008). This ecocidal view is widely accepted not only by the scientific community but also by society, thanks to its popularization by the mass media
Late Holocene vegetation dynamics and deforestation in Rano Aroi: implications for Easter Island's ecological and cultural history
Easter Island (Rapa Nui) has been considered an example of how societies can cause their own destruction through the overexploitation of natural resources. The flagship of this ecocidal paradigm is the supposed abrupt, island-wide deforestation that occurred about one millennium ago, a few centuries after the arrival of Polynesian settlers to the island. Other hypotheses attribute the forest demise to different causes such as fruit consumption by rats or aridity but the occurrence of an abrupt, island-wide deforestation during the last millennium has become paradigmatic in Rapa Nui. We argue that such a view can be questioned, as it is based on the palynological study of incomplete records, owing to the existence of major sedimentary gaps. Here, we present a multiproxy (pollen, charcoal and geochemistry) study of the Aroi core, the first gap-free sedimentary sequence of the last millennia obtained to date in the island. Our results show changing vegetation patterns under the action of either climatic or anthropogenic drivers, or both, depending on the time interval considered. Palm forests were present in Aroi until the 16th century, when deforestation started, coinciding with fire exacerbation elikely of human origine and a dry climate. This is the latest deforestation event recorded so far in the island and took place roughly a century before European contact. In comparison to other Easter Island records, this record shows that deforestation was neither simultaneous nor proceeded at the same pace over the whole island. These findings suggest that Easter Island's deforestation was a heterogeneous process in space and time, and highlights the relevance of local catchment traits in the island's environmental and land management history
Seasonal patterns of pollen sedimentation in Lake Montcortès (Central Pyrenees) and potential applications to high-resolution paleoecology: a 2-year pilot study
14 páginas, 2 tablas, 10 figuras.Lakes with varved sediments are especially
well suited for paleoecological study, from annual to
even seasonal resolution. The interpretative power of
such high-resolution paleoenvironmental reconstructions
relies on the availability of modern analogs with
the same temporal resolution. We studied seasonal
pollen sedimentation in varved Lake Montcorte`s, Central
Pyrenees (Spain), as a modern analog for highresolution
reconstruction of Late Holocene vegetation
and landscape dynamics. Seasonal samples were
obtained from sediment traps that were submerged near
the maximum water depth for a 2-year period (fall 2013
to fall 2015). Seasonal pollen sedimentation was compared
with meteorological variables from a nearby
weather station. Bulk pollen sedimentation, dominated
by Pinus (pine) and Quercus (oak), followed a clear
seasonal pattern that peaked during the spring/summer,
coinciding with maximum temperature and precipitation,
minimum relative humidity and moderate winds
from the SSE. Pollen sedimentation lags (PSL) were
observed formost pollen types, as substantial amounts of
pollen were found in the traps outside of their respective
flowering seasons. Two pollen assemblages were clearly
differentiated by their taxonomic composition, corresponding
to spring/summer and fall/winter. This pattern
is consistent with existing interpretation of the sediment
varves, specifically, that varves are formed by two-layer
couplets that represent the same seasonality as pollen.
We concluded that pollen sedimentation in Lake
Montcorte`s exhibits a strong seasonal signal in the
quantity of pollen, the taxonomic composition of the
pollen assembalges, and relationships between the pollen
and meteorological variables. Thus, varved sediments
provide a potentially powerful tool for paleoecological
reconstruction at seasonal resolution. This method could
be used not only to identify paleoenvironmental trends,
but also to identify annual layers and therefore date
sediments, even in the absence of evident sediment
laminations. A satisfactory explanation of PSL will
require further studies that examine internal lake
dynamics and pollen production/dispersal patterns.This work was funded by the Ministry of

Climate changes and cultural shifts on Easter Island during the last three millennia
Easter Island's cultural shifts have been explained mostly by anthropogenic forcing and climate changes have been dismissed as relevant drivers of societal change. Recent findings demand a more complex scenario in which climatic, ecological and cultural factors interact
Vegetation and landscape around Lake Montcortès (Catalan pre-Pyrenees) as a tool for palaeoecological studies of lake sediments
Vegetation and landscape around Lake Montcortès (Catalan pre-Pyrenees) as a tool for palynological studies of lake sediments. Lake Montcortès (42º 19′ N, 0º 59′ E; 1,027 m elevation) is an excellent target for high-resolution palaeoecological studies because its annually-laminated sediments extending back to the early-middle Holocene. The detailed knowledge of present vegetation patterns around the lake and the pollen they release to lake sediments is essential for a reliable interpretation of past vegetation dynamics. This study aims to identify and map the vegetation types currently growing around the lake. For this purpose, a quadrangular area of ca. 48 ha was defined. The floristic study resulted in a catalogue of 534 species. Vegetation analysis was based on 42 phytosociological inventories used to synthesise and map the relevant plant landscape units. As a result, we obtained 52 vegetation units as expressions of the CORINE habitats previously defined for Catalonia. Each of these habitats was described in floristic, physiognomic, phytogeographic, environmental and human-use terms. The next step will be the palynological study of the more representative species of the described vegetation types, as a means to optimise future palynological interpretations

Macrofossils in Raraku Lake (Easter Island) integrated with sedimentary and geochemical records: Towards a palaeoecological synthesis for the last 34,000 years
Macrofossil analysis of a composite 19m long sediment core from Rano Raraku Lake (Easter Island) wasrelated to litho-sedimentary and geochemical features of the sediment. Strong stratigraphical patterns are shown by indirect gradient analyses of the data. The good correspondence between the stratigraphical patterns derived from macrofossil (Correspondence Analysis) and sedimentary and geochemical data (Principal Component Analysis) shows that macrofossil associations provide sound palaeolimnological information in conjunction with sedimentary data. The main taphonomic factors influencing the macrofossil assemblages are run-off from the catchment, the littoral plant belt, and the depositional environment within the basin. Five main stages during the last 34,000 calibrated years BP (calyrBP) are characterised from the lithological, geochemical, and macrofossil data. From 34 to 14.6calkyrBP (last glacial period) the sediments were largely derived from the catchment, indicating a high energy lake environment with much erosion and run-off bringing abundant plant trichomes, lichens, and mosses into the centre of Raraku Lake. During the early Holocene the infilling of the lake basin and warmer conditions favoured the growth of a littoral plant belt that obstructed terrigenous input. Cladoceran remains and Solanaceae seeds are indicative of reduced run-off and higher values of N and organic C indicate increased aquatic and catchment productivity. From 8.7 to 4.5calkyrBP a swamp occupied the entire basin. The increase of Cyperaceae seeds reflects this swamp development and, with oribatid mites and coleopteran remains, indicates a peaty environment and more anoxic conditions in Raraku. At around 4.5calkyrBP dry conditions prevented peat growth and there is a sedimentary hiatus. About 800calyrBP, peat deposition resumed. Finally, in the last few centuries, a small lake formed within the surrounding swamp. Evidence of human activity is recorded in these uppermost sediments. © 2011 Elsevier Ltd.This research was funded by the Spanish Ministry of Science and Education through the projects LAVOLTER (CGL2004-00683/BTE), GEOBILA (CGL2007-60932/BTE) and CONSOLIDER GRACCIE (CSD2007-00067) and an undergraduate grant (BES-2008-002938 to N.
