Land use changes, landscape ecology and their socioeconomic driving forces in the Spanish Mediterranean coast (the Maresme County, 1850-2005)

[cat] Utilitzem un conjunt de mètriques del paisatge per estudiar l'evolució a llarg termini seguida en una típica zona costanera del Mediterrani des de 1850 fins a 2005, que mostren una greu deterioració del medi ambient entre 1950 i 2005. Les principals forces motores d'aquesta degradació del paisatge han estat el creixement urbà experimentat a les antigues zones agrícoles situades a les planes litorals, juntament amb l'abandonament i la reforestació dels vessants dels pujols interceptats per àrees residencials de baixa densitat, carreteres i altres infraestructures lineals. Duem a terme una anàlisi estadística de redundància (RDA) amb la finalitat d'identificar els que considerem com alguns agents rectors socioeconòmics i polítics d'última instància d'aquests impactes ambientals. Els resultats confirmen les nostres hipòtesis interpretatives, que són que: 1) els canvis en les cobertes i usos del sòl determinen canvis en les propietats dels paisatge, tant estructurals com funcionals; 2) aquests canvis no es produeixen per atzar, sinó que estan relacionats amb factors geogràfics i forces socioeconòmiques i polítiques.

The Achieved Dreams of a Neighborhood

This article explains the social transformation process initiated at the end of the 1970s within the neighborhood of La Verneda-Sant Martı´ in Barcelona. This process started with the foundation of an adult education center that was organized as a Learning Community (the first one in the world). From the beginning, it was administered for and by the community. It became a space of debate where the demands and dreams of the neighbors converged about transforming their neighborhood along with the recommendations of the international scientific community. Twenty years later, the dreams came true: There have been substantial improvements throughout the urban space, infrastructures, housing, urban thoroughfares, and public highways. The INCLUD-ED European project, using the communicative methodology of research, has thoroughly studied the transformation carried out in the La Verneda-Sant Martı´ Adult School and its neighborhood. INCLUD-ED has identified successful practices within diverse social areas that are transferable to other contexts and contribute to overcoming inequalities and improving the most underprivileged neighborhoods.

Lentoaseman terminaalirakennuksen energiankäyttö ja sisäilmasto

Diplomityössä tarkasteltiin lentoaseman terminaalirakennuksen energia- ja ainevirtoja sekä sisäilman ominaisuuksia. Esimerkkikohteena oli Helsinki-Vantaan lentoaseman keskiterminaalirakennus, jonka 1. ja 2. rakennusvaiheen ulkovaippa muodosti taserajan. Taseen ulkopuolisista tekijöistä tarkasteltiin jäähdytysenergian tuotantoa ja ulkoilman laatua. Työn yhtenä tavoitteena oli muodostaa rakennukselle energiatase. Taseen avulla saatiin tietoa energian jakautumisesta eri toimintoihin ja löydettiin tekijät, joita suunnittelussa tulee painottaa. Terminaalin lähiympäristössä tutkittiin ulkoilman laatua mittausten avulla. Mittaustietoja käytetään apuna tulevaisuuden ilmanottosuunnittelussa. Työssä tarkasteltiin energia- ja ainevirtoina lämpö-, jäähdytys- ja sähköenergian sekä veden ostoa, tuotantoa ja kulutusta sekä prosessointia. Terminaalin lämpötarpeesta hieman yli puolet katettiin kaukolämmöllä. Loput noin 45 % lämpöenergiasta saatiin ns. ilmaisenergioista. Näistä merkittävimmäksi havaittiin sähkölaitteiden luovuttama lämpömäärä. Lämpöhäviöiden kannalta merkittäviä energiavirtoja olivat ilmanvaihdon ja vuotoilmojen kautta siirtyvät energiavirrat, joiden osuuden todettiin olevan noin 80 % terminaalin kokonaislämpöhäviöistä. Vaipan lämmöneristyskyky ja kyky absorboida auringon säteilyä todettiin hyviksi. Tulevaisuudessa tärkeitä suunnittelunäkökohtia tulevat olemaan ilmanvaihdon ja vuotoilman kautta siirtyvien energiavirtojen hallinta sekä sähköenergian ominaiskulutuksen pienentäminen. Ulkoilma todettiin mittauksin hyvätasoiseksi. Lento- ja maaliikenteen päästöarvot olivat lähellä toisiaan ja selvästi ohjearvoja alemmalla tasolla. Päästöjen sijaintiin vaikuttivat liikennemääriä enemmän tuuliolosuhteet. Tulevaisuudessa tuloilma voidaan johtaa terminaaliin yhtä hyvin joko lento- tai maaliikenteen puolelta.

Building Partnerships and Fostering Activities to Promote English Outside the Classroom

Becoming proficient in at least one foreign language is a target for educational authorities throughout Europe. The question is how we can improve our students’ command of English without increasing the workload on teachers and without much funding. In El Prat de Llobregat, a city located in the vicinity of Barcelona, we have addressed that issue by creating a group of teachers, educational advisors and city council administrators, who have been acting in a coordinated way to enhance English language exposure beyond the classroom. Our interest in promoting English stems from our location: our municipality is situated next to an international airport where finding a job is bound to be dependent on English fluency. We aim to show that, through a network of members at school and administrative levels, an array of meaningful and empowering initiatives can be implemented in a city where resources are scarce and cultural backgrounds diverse.

Konepajateollisuuden komponenttitoimittajasta järjestelmätoimittajaksi

Konepajateollisuuden suurasiakkaiden kansainvälistymisen myötä on noussut esiin uusia haasteita ja tarpeita, joihin yritysten tulisi pystyä vastaamaan kilpailukyvyn säilyttämiseksi. Konepajateollisuudessa tämä tarkoittaa entistä tiukempaa keskittymistä ydinosaamisalueisiin, kilpailuedun säilyttämistä, kustannustason sekä laadun hallintaa ja tehtävien jakoa päämiehiltä omille toimittajilleen verkostossa. Toimittajaverkostoissa toimii lukuisa määrä erikokoisia ja - tasoisia alihankkijoita, joista päämiesten lähimpinä toimittajina ovat niin kutsutut järjestelmätoimittajat. Tässä diplomityössä on tutkittu verkostoitumista ja sen perusteita lähinnä konepajateollisuuden kannalta, alan alihankintaverkostoa yleisesti sekä paikallisesti eteläisessä Kymenlaaksossa. Järjestelmätoimittajuuteen on kiinnitetty erityistä huomiota. Työssä on haettu sellaisia pk-yrityksiltä vaadittavia toimenpiteitä ja ominaisuuksia, jotta nouseminen jonkun päähankkijan komponenttitoimittajasta järjestelmätoimittajaksi olisi mahdollista. Aihetta on tarkasteltu teoreettisesti tutkimusten, julkaisujen ja kirjallisuuden avulla. Tämän lisäksi on suoritettu benchmarkkauksia muutamille menestyneille, konepajateollisuudessa toimiville ja järjestelmätoimittajiksi kehittyneille yrityksille. Näiden kerättyjen tietojen perusteella on tehty johtopäätöksiä ja niistä edelleen käytännön kehitystoimenpiteiden ja vaatimusten kartoitus sekä toimintasuunnitelma eräälle Kymenlaakson seudulta olevalle metallialan pk-yritykselle, jolla on tunnistettu olevan mahdollisuudet kehittyä järjestelmätoimittajaksi ja mitä liiketoimintamallia yrityksen johto pitää varteenotettavana vaihtoehtona ja kiinnostavana mahdollisuutena.

From the Olympic dream to a down to earth approach: Lausanne's sports events hosting strategy

In the context of globalized competition among territories, cities, regions and countries have to find new ways to be attractive to companies, investors, tourists and residents. In that perspective, major sports events (such as the Olympic Games or the FIFA World Cup) are often seen as a lever for territorial development. Based on that idea, many sports events hosting strategies have emerged in the 1980s and 1990s. However, the growing competition in the sports events' market and the gigantism of those major events, forced some territories to turn to smaller events. This necessary resize of their strategy raises the question of their capacity to meet the initial objectives, which aim usually at developing the economy and promoting the image of the host destination. This essay sketches out the evolution of a sports events hosting strategy in a city that does not have the resources (either financial, human or in terms of infrastructures) to attract major international sports events. The challenges they have to face and a possible solution based on the event portfolio perspective are discussed through the article.

Association of car ownership and physical activity across the spectrum of human development : Modeling the Epidemiologic Transition Study (METS).

BACKGROUND: Variations in physical activity (PA) across nations may be driven by socioeconomic position. As national incomes increase, car ownership becomes within reach of more individuals. This report characterizes associations between car ownership and PA in African-origin populations across 5 sites at different levels of economic development and with different transportation infrastructures: US, Seychelles, Jamaica, South Africa, and Ghana. METHODS: Twenty-five hundred adults, ages 25-45, were enrolled in the study. A total of 2,101 subjects had valid accelerometer-based PA measures (reported as average daily duration of moderate to vigorous PA, MVPA) and complete socioeconomic information. Our primary exposure of interest was whether the household owned a car. We adjusted for socioeconomic position using household income and ownership of common goods. RESULTS: Overall, PA levels did not vary largely between sites, with highest levels in South Africa, lowest in the US. Across all sites, greater PA was consistently associated with male gender, fewer years of education, manual occupations, lower income, and owning fewer material goods. We found heterogeneity across sites in car ownership: after adjustment for confounders, car owners in the US had 24.3 fewer minutes of MVPA compared to non-car owners in the US (20.7 vs. 45.1 minutes/day of MVPA); in the non-US sites, car-owners had an average of 9.7 fewer minutes of MVPA than non-car owners (24.9 vs. 34.6 minutes/day of MVPA). CONCLUSIONS: PA levels are similar across all study sites except Jamaica, despite very different levels of socioeconomic development. Not owning a car in the US is associated with especially high levels of MVPA. As car ownership becomes prevalent in the developing world, strategies to promote alternative forms of active transit may become important.

Geospatial approach for defining the Wildland-Urban Interface in the Alpine environment

Problems related to fire hazard and fire management have become in recent decades one of the most relevant issues in the Wildland-Urban Interface (WUI), that is the area where human infrastructures meet or intermingle with natural vegetation. In this paper we develop a robust geospatial method for defining and mapping the WUI in the Alpine environment, where most interactions between infrastructures and wildland vegetation concern the fire ignition through human activities, whereas no significant threats exist for infrastructures due to contact with burning vegetation. We used the three Alpine Swiss cantons of Ticino, Valais and Grisons as the study area. The features representing anthropogenic infrastructures (urban or infrastructural components of the WUI) as well as forest cover related features (wildland component of the WUI) were selected from the Swiss Topographic Landscape Model (TLM3D). Georeferenced forest fire occurrences derived from the WSL Swissfire database were used to define suitable WUI interface distances. The Random Forest algorithm was applied to estimate the importance of predictor variables to fire ignition occurrence. This revealed that buildings and drivable roads are the most relevant anthropogenic components with respect to fire ignition. We consequently defined the combination of drivable roads and easily accessible (i.e. 100 m from the next drivable road) buildings as the WUI-relevant infrastructural component. For the definition of the interface (buffer) distance between WUI infrastructural and wildland components, we computed the empirical cumulative distribution functions (ECDF) of the percentage of ignition points (observed and simulated) arising at increasing distances from the selected infrastructures. The ECDF facilitates the calculation of both the distance at which a given percentage of ignition points occurred and, in turn, the amount of forest area covered at a given distance. Finally, we developed a GIS ModelBuilder routine to map the WUI for the selected buffer distance. The approach was found to be reproducible, robust (based on statistical analyses for evaluating parameters) and flexible (buffer distances depending on the targeted final area covered) so that fire managers may use it to detect WUI according to their specific priorities.

What hurts the dominant airlines at hub airports?

This paper estimates a frequency equation to explain the determinants of network airline service levels at their hub airports. Drawing on European data for 2002 - 2013, we find that network airlines reduce frequencies when the share of low - cost airlines increases both on the route and at the hub airport. On the contrary, frequency choices of network airlines are not affected by competition from low - cost airlines operating in nearby secondary airports. We also find some evidence that mergers in Europe may result in a re - organization of the route structure in favor of the hubs of the larger airline.

Does privatization spur regulation? Evidence from the regulatory reform of European airports

This paper conducts an empirical analysis of the relationship between privatization and regulation drawing on data from a wide sample of European airports. We find that privatization promotes a shift from basic regulation to a situation of more detailed or non-regulation, depending on the specific characteristics of the privatization process and on the type of airport being privatized. Moreover, we report a significant association between high traffic volumes and more detailed regulation. By contrast, airports where slot allocation is noncoordinated are significantly associated with non-regulation.

Safety and sustainability research for university schools of fine arts

Designing new teaching programs for both undergraduate and graduate university studies involves integrating concepts and methodologies regarding quality, work safety and hazard prevention, and environmental protection. One of the challenges facing Spanish research within the realm of European Higher Education concerns health and safety issues in the Arts.In the case of Fine Arts, student exploration is one of the fundamental pillars of the study program; therefore it is imperative that art studios be optimized. This optimization affects both designated resources (infrastructures, materials, equipment, etc.) and organization of the teaching force.In this context, the aim of our research is to improve educational practices by designing quality measures that are both friendly to the environment and hazardous free. The aim here is to assure adequate art studio and laboratory management, and provide students with hazard free health and environmentally safe concepts that can be incorporated in their professional lives.The school of Fine Arts at the University of Barcelona is part of a pilot program, where our experience in educational innovation and research is serving as a reference for the implantation of OSHAS 18001 norms.
