Arctic warming will promote Atlantic-Pacific fish interchange

Throughout much of the Quaternary Period, inhospitable environmental conditions above the Arctic Circle have been a formidable barrier separating most marine organisms in the North Atlantic from those in the North Pacific(1,2). Rapid warming has begun to lift this barrier(3), potentially facilitating the interchange of marine biota between the two seas(4). Here, we forecast the potential northward progression of 515 fish species following climate change, and report the rate of potential species interchange between the Atlantic and the Pacific via the Northwest Passage and the Northeast Passage. For this, we projected niche-based models under climate change scenarios and simulated the spread of species through the passages when climatic conditions became suitable. Results reveal a complex range of responses during this century, and accelerated interchange after 2050. By 2100 up to 41 species could enter the Pacific and 44 species could enter the Atlantic, via one or both passages. Consistent with historical and recent biodiversity interchanges(5,6), this exchange of fish species may trigger changes for biodiversity and food webs in the North Atlantic and North Pacific, with ecological and economic consequences to ecosystems that at present contribute 39% to global marine fish landings.

Sex-specific selective pressures on body mass in the greater white-toothed shrew, Crocidura russula.

The direction, intensity and shape of viability-, sexual- and fecundity selection on body mass were investigated in a natural population of the greater white-toothed shrew (Crocidura russula), combining parentage assignment through molecular techniques and mark-recapture data over several generations. A highly significant stabilizing viability selection was found in both sexes, presumably stemming from the constraints imposed by their insectivorous habits and high metabolic costs. Sexual selection, directional in both sexes, was twice as large in males than in females. Our results suggest that body mass matters in this context by facilitating the acquisition and defense of a breeding territory. No fecundity selection could be detected. The direction of sexual size dimorphism (SSD) was in agreement with the observed pattern of selective pressures: males were heavier than females, because of stronger sexual selection. SSD intensity, however, was low compared with other mammals, because of the low level of polygyny, the active role of females in territory defense and the intensity of stabilizing viability selection.

Reenginyeria inversa d'aplicacions J2EE

L'objectiu d'aquest Projecte Final de Carrera es el de trobar eines que a partir del codi font d'una aplicació J2EE generin diagrames que facilitin entendre el disseny de l'aplicació per tal de facilitar-ne la modificació a un nou equip que no hagués participat en la seva creació. El treball es centra en veure quins diagrames genera cada eina, i quina informació proporcionen aquests diagrames pensant en una possible modificació d'una aplicació J2EE que no haguem desenvolupat nosaltres en un futur.

Making the Link Between Obesity and wellbeing

Making the links between Obesity & Well-being. A briefing paper developed for Care Services Improvement Partnership (CSIP) North West. The paper covers the epidemiology and evidence of links between health and obesity. Mental well-being is a key factor of obesity and weight management. Good mental health is a protective factor for good physical health and against physical illness and is essential for making healthy lifestyle choices and behaviour changes. Poor mental health can lead to unhealthy lifestyle choices and unhealthy weight management. Obesity and physical illness can also lead to poor mental health. People with mental health problems, especially severe, are also at increased risk of obesity and related poor health. In order to ensure that strategies and programmes effectively address the relevant mental well-being factors, a mental well-being impact assessment (MWIA) could be undertaken. This process is based on health impact assessment methodology and a set of evidence based mental well-being determinants and factors, grouped under the four themes of enhancing control, increasing resilience and community assets, facilitating participation and promoting inclusion. The process also involves identifying indicators to measure progress. Evaluation shows it is effective in engaging stakeholders in service development and evaluation and it increases understanding of mental well-being and its determinants.

Així mateix renovem la imatge de la nostra organització, adequant-la als temps actuals.

Jugant a definir ciència : una eina per treballar amb infants, llenguatge i coneixement especialitzat de manera integrada

Treball desenvolupat en el marc del projecte "La construcció del coneixement científic: primeres representacions" de l'IULA de la Universitat Pompeu Fabra (Estopà, 2008), l'objectiu principal del qual és desenvolupar una eina que ajudi a mestres i educadors a l'hora de treballar les dues branques fonamentals del coneixement, les ciències i les lletres, de manera simultània, sense oblidar-ne una per afavorir l'altra. Es tracta d'una eina que, des de la lexicologia i la terminologia, a través del joc, ajudi a conceptualitzar correctament termes de ciència, els dessacralitzi i atregui els infants al coneixement científic.

The relationships between technology and open education in the development of a resilient higher education

The place of technology in the development of coherent educational responses to environmental and socio-economic disruption is here placed under scrutiny. One emerging area of interest is the role of technology in addressing more complex learning futures, and more especially in facilitating individual and social resilience, or the ability to manage and overcome disruption. However, the extent to which higher education practitioners can utilise technology to this end is framed by their approaches to the curriculum, and the socio-cultural practices within which they are located. This paper discusses how open education might enable learners to engage with uncertainty through social action within a form of higher education that is more resilient to economic, environmental and energy-related disruption. It asks whether open higher education can be (re)claimed by users and communities within specific contexts and curricula, in order to engage with an uncertain world.

La organización de recursos digitales y la oferta de servicios documentales en un entorno virtual de aprendizaje

El creixement d'usuaris potencials i el de l'oferta de serveis per part de la Biblioteca Virtual de l'UOC, va generar un procés de reflexió estratègica per donar resposta a nou escenari de l'organització. El resultat ha estat tres eixos o línies d'actuació que permetin afrontar aquest canvi i creixement: organització dels recursos en una base de dades, el desenvolupament dels serveis "push" i el facilitar l'accés a la biblioteca des de qualsevol entorn i de forma personalitzada a aquest.

Aplicación de un estudio de usabilidad en bibliotecas digitales : la Biblioteca Virtual de la UOC

The Open University of Catalonia (UOC) has conducted a study of operability of its user interfaces, creating for this purpose different work groups that have analyzed different casuistries. One of these groups focused on the study and analysis of the usability of the Virtual Library's website, with the objective of obtaining benefits for our users. As a result of this analysis, an important qualitative jump is occurring in the new implementation of the website of the UOC's Virtual Library, prioritizing the role of users from different points of view: ease of navigation, management of profiles and the services associated to these and the restructuring of the information architecture, with the final aim of facilitating access to the resources and the services offered from the Library, advocating in this way for their quality and improvement.

La gestió dels recursos documentals a les aules de la UOC

La gestió dels recursos documentals a les aules de la UOC es fa de manera compartida entre el professorat i la Biblioteca de la Universitat. La responsabilitat dels continguts que trobem com a 'recursos de l'aula' i de l'actualització d'aquests recau en el professor/a responsable de l'assignatura que és qui decideix quins recursos electrònics han de tenir les aules de les seves assignatures i comunica a la Biblioteca aquests recursos i les possibles actualitzacions i/o modificacions que cal fer-hi. La gestió d'aquests recursos que es fa des de la biblioteca és un element clau perquè, a través d'aquest procés, la biblioteca esdevingui un element realment facilitador de l'aprenentatge i la docència, i situa la biblioteca com un element central en el model d'aprenentatge de la UOC. S'inclou al final de la presentació un seguit de recomanacions per a l'èxit dels recursos documentals a les aules virtuals.

La gestió dels recursos documentals a les aules de la Universitat Oberta de Catalunya

The management of the documental resources in the classrooms of the UOC is shared between the teaching staff and the Library of the University. The responsibility of the contents that we find as "resources of the classroom" and updating these falls on the teacher responsible for the course which is the one who decides which electronic resources must have the classrooms of his/her courses and communicates these resources and the possible updates or modifications to the Library. The management of these resources done from the library is a key element because, through this process, the library becomes a really facilitating element of the learning and the teaching, and places the library like a central element in the learning model of the UOC. A series of recommendations for the success of the documental resources in the virtual classrooms are included at the end of the presentation.

Análisis del modelo salutogénico en España: aplicación en salud pública e implicaciones para el modelo de activos en salud

This article seeks to provide an in depth review about one of the most revolutionary and influential methods used in understanding the variables and processes that explain human health. Based on a new vision in the analysis of the consequences of theNazi Holocaust, a doctor-sociologist—Aaron Antonovsky— managed to influence medicine and behavioral science by facilitating the keys for the optimal development of public health today. Despite the fact that this theory began appearing in the1970s in the 20th century, its real development and expansion have been seen in recent years. In fact, in Spain, there is littlescientific literature that analyses the theoretic keys of the model in depth. This work seek to cover this gap; to achieve this objective, it first presents how the construct of salutogenesis arose, the social-cultural context that promoted it, as well as the importance public health acquires today. This is the aim of this work, which analyses the theoretical bases of the salutogenesis model,with specific emphasis on its background and precursors, aswell as its inception, development and current expansion
