Quatre dècades de recerca a les illes Medes

Fa exactament 30 anys, l’agost de 1982, un de nosaltres signava la presentació (Ros, 1984a) del volum Els sistemes naturals de les illes Medes, que no veuria la llum fins dos anys després (Ros, Gili i Olivella, 1984). Fou aquell un esforç col·lectiu important, en el que participaren 54 autors, que al llarg de més de vuit-centes pàgines, 42 capítols i una vintena de làmines i mapes desplegables explicava tot el que llavors se sabia de l’entorn físic, la flora, la fauna i les comunitats, marines i terrestres, delpetit arxipèlag empordanès. L’esperó del llibre havien estat uns projectes de recerca, modestos si es comparen amb els actuals, endegats per joves llicenciats, estudiants i afeccionats que al llarg de ladècada prèvia exploraren extensivament els fons de les illes, en mostrejaren les comunitats i en feren diversos estudis faunístics, florístics i comunitaris relativament complets.

L’alguer de Posidonia oceanica de les illes Medes: més de trenta anys d’estudi

Fins on hem pogut esbrinar, el primer estudi publicat en una revista científica sobre la praderia o alguer de Posidonia oceanica de les illes Medes és el de De Haro (1965). En aquella època, la investigació delsfons marins estava als seus inicis i probablement la praderia de les illes Medes va ser un dels primers llocs en què, amb mitjans força precaris i a càrrec d’uns joves estudiants, es van efectuar prospeccions en immersió, tècnica que tot just començava però que molt ràpidament havia de substituir les dragues ialtres artefactes menys fiables. Amb el Programa de Bentos, entre 1972-1974 (Ros, 1982) –precisament aquest autor (vegeu el capítol 1) era un d’aquells «joves estudiants»; l’altre era en Jordi Camp, actualment investigador del CSIC–, la recerca bentònica va agafar un primer impuls i l’escafandre autònom es va incorporar plenament com a eina d’observació i mostreig. Durant aquest programa, es va situar una de les estacions de treball a les illes Medes, i l’alguer de Posidonia va ser un dels hàbitats objecte d’estudi, tot i que més aviat amb un objectiu faunístic i biocenòtic que estrictament ecològic.

El coral·ligen de les illes Medes: una comunitat fràgil amb un gran valor patrimonial

El coral·ligen ha estat definit com una bioconstrucció formada sobretot per algues calcàries de la família de les coral·linàcies, principalment dels gèneres Lithophyllum, Lithothamnion, Mesophyllum,Neogoniolithon, Peyssonnelia i Halimeda, que es desenvolupen entre 20 i 120 m de fondària, on la poca disponibilitat de llum limita el creixement de les algues fotofil·les (Ballesteros, 2006). En aquestescondicions, les espècies d’algues carbonatades passen a ser dominants i, juntament amb diferents espècies d’invertebrats, desenvolupen unes comunitats amb una forta complexitat estructural.Originalment, el coral·ligen es va descriure en el segle XIX a la zona de Marsella (Marion, 1833). El nom, coral·ligen, estava relacionat amb la “producció” de corall vermell Corallium rubrum per part deles bioconstruccions algals. De fet, a la zona de Marsella el corall vermell era un recurs pesquer molt important en aquella època i d’aquí, probablement, que s’emprès el terme. Tanmateix, el terme englobael conjunt de comunitats dominades per diferents algues calcàries i invertebrats que, independentment de la seva composició, estan caracterizades per desenvolupar importants bioconcrecions (fins a 2 m d’alçada) en diferents zones geogràfiques de la Mediterrània.

A bioeconomic model for Mediterranean fisherires, the hake off Catalonia (western Mediterranean) as a case study

The theoretical aspects and the associated software of a bioeconomic model for Mediterranean fisheries are presented. The first objective of the model is to reproduce the bioeconomic conditions in which the fisheries occur. The model is, perforce, multispecies and multigear. The main management procedure is effort limitation. The model also incorporates the usual fishermen strategy of increasing efficiency to obtain increased fishing mortality while maintaining the nominal effort. This is modelled by means of a function relating the efficiency (or technological progress) with the capital invested in the fishery and time. A second objective is to simulate alternative management strategies. The model allows the operation of technical and economic management measures in the presence of different kind of events. Both deterministic and stochastic simulations can be performed. An application of this tool to the hake fishery off Catalonia is presented, considering the other species caught and the different gears used. Several alternative management measures are tested and their consequences for the stock and economy of fishermen are analysed.

Sharing and Learning= Changing. A real story at the Institute of Public Security of Catalonia

The Institute has professionals with extensive experience in training, specifically with experience in the field of police and emergencies training. Moreover, it also has very talented people. But above all, our institution has public professionals with a desire to serve, who love security and emergency responders and want to provide them with the best knowledge to make them every day better professionals. In the quest for continuous training improvement, its during 2009 when e-learning begins to have a presence at the Institute. Virtual training methodology becomes a facilitator for the training of various professionals, avoiding geographical displacement and easing the class schedule.

Are we living longer but less healthy? Trends in mortality and morbidity in Catalonia (Spain), 1994-2011

Evidence on trends in prevalence of disease and disability can clarify whether countries are experiencing a compression or expansion of morbidity. An expansion of morbidity as indicated by disease have appeared in Europe and other developed regions. It is likely that better treatment, preventive measures and increases in education levels have contributed to the declines in mortality and increments in life expectancy. This paper examines whether there has been an expansion of morbidity in Catalonia (Spain). It uses trends in mortality and morbidity from major causes of death and links of these with survival to provide estimates of life expectancy with and without diseases and functioning loss. We use a repeated cross-sectional health survey carried out in 1994 and 2011 for measures of morbidity; mortality information comes from the Spanish National Statistics Institute. Our findings show that at age 65 the percentage of life with disease increased from 52% to 70% for men, and from 56% to 72% for women; the expectation of life unable to function increased from 24% to 30% for men and 40% to 47% for women between 1994 and 2011. These changes were attributable to increases in the prevalences of diseases and moderate functional limitation. Overall, we find an expansion of morbidity along the period. Increasing survival among people with diseases can lead to a higher prevalence of diseases in the older population. Higher prevalence of health problems can lead to greater pressure on the health care system and a growing burden of disease for individuals.

FROM TOTAL INSTITUTION TO EXTITUTION? Discussions on the future of monastic life in the Benedictine women’s monasteries of Catalonia (Spain

On the 50th anniversary of the creation of the Federation of Benedictine Women’s Monasteries of Catalonia (Spain), the five monasteries represented are discussing the following question: what will monastic life be like in the future? This question is added to the debate about “new forms of monasticism”, “urban monastic life” and, in a more general sense, to the modernisations and “the opening up” of the precepts and practices of monastic life at this time. Faced with the ambitious monastic questioning, the author responds with five deliberately provocative debates developed out of a consideration of various chapters of the Rule of St. Benedict that raise profound questions when it comes to responding to the question presented here. Having described these five debates, by way of a summary, the article presents three ideal types of monastery in relation to the current processes of deinstitutionalisation that represent, in an overall way, three provisional responses and serve as a focus for the question discussed here.

La migració primaveral d'ocells als Aiguamolls de l'Empordà (Girona): primer anellament de Becadell Gros (Gallinago Media) a la Península Ibèrica

En aquest treball s'exposen els resultats obtinguts en la campanya 1994 d'anellament d'ocells inclosa dins del projecte italià Piccole Isole. Es demostra que el factor meteorològic afecta directament la fenologia migratòria de diferents espècies d'ocells. Es pretén també estudiar la influència dels diferents hàbitats en el nombre i en la diversitat de captures. Es recullen també en aquest treball les principals espècies visualitzades durant la campanya, com també l'elevat nombre de controls estrangers recuperats. Dintre de les captures i l'anellament posterior, destaca sobretot la d'un becadell gros (Gallinago media) fets per primera vegada a la peninsula Ibèrica

Accessing Legal Information in Catalonia. Open Acces to Legislation and Case Law

The article outlines free online legal resources to conduct research on Catalan and Spanish legislation and case-law. Most of these resources are primary sources made public by government bodies. The list shows how the Spanish and Catalan governments, in their attempt to promote equal access to legislation and case-law, cover the different jurisdictions. The text also mentions some resources to conduct historical legal research about legislation and case law, and some free legal private websites.

Viticulture under climate change : understanding vulnerability and adaptive capacity of wineries and growers. A case study in El Penedès region, Catalonia

Climate change may pose challenges and opportunities to viticulture, and much research has focused in studying the likely impacts on grapes and wine production in different regions worldwide. This study assesses the vulnerability and adaptive capacity of the viticulture sector under changing climate conditions, based on a case study in El Penedès region, Catalonia. Farm assets, livelihood strategies, farmer-market interactions and climate changes perceptions are analysed through semi-structured interviews with different types of wineries and growers. Both types of actors are equally exposed to biophysical stressors but unevenly affected by socioeconomic changes. While wineries are vulnerable because of the current economic crisis and the lack of diversification of their work, which may affect their income or production, growers are mainly affected by the low prices of their products and the lack of fix contracts. These socioeconomic stressors strongly condition their capacity to adapt to climate change, meaning that growers prioritize their immediate income problems, rather than future socioeconomic or climate threats. Therefore, growers undertake reactive adaptation to climate changing conditions, mainly based on ancient knowledge, whilst wineries combine both reactive and anticipatory adaptation practices. These circumstances should be addressed in order to allow better anticipatory adaptation to be implemented, thus avoiding future climate threats.

Proposal of three thermodynamic variables to discriminate between storms associated with hail and storms with intense rainfall in Catalonia (Proposta de tres variables termodinàmiques per discriminar entre tempestes amb pedregades i tempestes amb pluges intenses)

Between late spring and early fall, the development of storms is common in Catalonia. Despite the fact that they usually produce heavy showers of short duration, they can also involve severe weather with ice pellets or hail. While the latter usually affect inland regions, and there are numerous publications on these cases; the analysis of events affecting the coast and causing damage to public and private properties is not so well developed. The aim of this study is to provide additional thermodynamic indicators that help differentiate storms with hail from storms without hail, considering cases that have affected various regions of Catalonia, mainly coastal areas. The aim is to give more information to improve prognosis and the ability to detail information in these situations. The procedure developed involved the study of several episodes of heavy rainfall and hail that hit Catalonia during the 2003-2009 period, mainly in the province of Girona, and validated the proposal during the campaign of late summer and fall of 2009, as well as 2012. For each case, several variables related to temperature, humidity and wind were analyzed at different levels of the atmosphere, while the information provided by the radio sounding in Barcelona was also taken into account. From this study, it can be concluded that the temperature difference between 500 hPa and 850 hPa, the humidity in the lower layers of the atmosphere and the LI index are good indicators for the detection of storms with associated hail.

Network characteristics of film tourism websites in Catalonia: an application of network analysis in tourism

This master thesis presents a research on the analysis of film tourism stakeholders in Catalonia applying the network analysis approach. The research aims to provide an analysis of the relations between local tourism stakeholders with local film offices through their websites. Therefore, the development of the present work involved the review of literature on the themes of film tourism and network analysis. Then the main stakeholders of film and tourism of Catalonia were identified and their websites analyzed. The measures indicators for network analysis such as centrality, closeness and betweenness degree have been applied on the analysis of the websites to determine the extent of the relations of film and tourism stakeholders in Catalonia. Results and conclusions are presented on the referred sections
