Forecasting the need for medical specialists in Spain: application of a system dynamics model

[EN] Background: Spain has gone from a surplus to a shortage of medical doctors in very few years. Medium and long-term planning for health professionals has become a high priority for health authorities. Methods: We created a supply and demand/need simulation model for 43 medical specialties using system dynamics. The model includes demographic, education and labour market variables. Several scenarios were defined. Variables controllable by health planners can be set as parameters to simulate different scenarios. The model calculates the supply and the deficit or surplus. Experts set the ratio of specialists needed per 1000 inhabitants with a Delphi method. Results: In the scenario of the baseline model with moderate population growth, the deficit of medical specialists will grow from 2% at present (2800 specialists) to 14.3% in 2025 (almost 21 000). The specialties with the greatest medium-term shortages are Anesthesiology, Orthopedic and Traumatic Surgery, Pediatric Surgery, Plastic Aesthetic and Reparatory Surgery, Family and Community Medicine, Pediatrics, Radiology, and Urology. Conclusions: The model suggests the need to increase the number of students admitted to medical school. Training itineraries should be redesigned to facilitate mobility among specialties. In the meantime, the need to make more flexible the supply in the short term is being filled by the immigration of physicians from new members of the European Union and from Latin America.

El paisaje como recurso turístico de la ciudad. Una propuesta metodológica para valorar el papel de la planificación del territorio en el caso de Las Palmas de Gran Canaria

[ES] Se propone una metodología para la valoración de las relaciones entre la ciudad, el turismo y la planificación del territorio desde la perspectiva del paisaje y el medio ambiente. Para ello, analizamos como las estrategias de mejora de la competitividad turística de las ciudades tienen su traslación en la planificación urbanística de los ayuntamientos y la relación o integración de los elementos que configuran ambientalmente el espacio urbano. Con este objeto genérico, se selecciona el ejemplo de Las Palmas de Gran Canaria como laboratorio de experiencias de ordenación del espacio, mediante las cuales puede observarse los indicadores y dificultades en el tratamiento de la calidad ambiental. Nos interesa distinguir cómo estos elementos ambientales se planifican como recursos turísticos y la relevancia que tienen en las estrategias públicas de la ordenación del territorio.

Minori rumeni tra percorsi migratori e rappresentazioni. Nè soli, nè accompagnati a Bologna

The thesis deals with the heterogenous category of the “unaccompanied minors”, concentrating the scientific work on those who migrate from Romania to the Italian city of Bologna. Between different migratory routes that include Romanian minors, I chose to explore the ones linked with the underground and illegal contexts. In order to analyse the reasons and the morphology of their migratory career, I used the multisituated field research which allowed me to consider the social policies in both the Romanian and the Italian environment. The main debate on the situation of the “unaccompanied children” refers to the extent to which these minors leave their country of origin “accompanied” by different adult figures and it also involves the role played by these adults. The first chapter is dedicated to a brief theoretical and methodological introduction to the main arguments of the thesis such as Romanian migration to Italy, trafficking in human beings, transnationality of migrant’s migration and decentered cooperation as a means of contrasting illegal migration and trafficking. Each field of research is characterized by a specific methodological approach, but they are all linked by the anthropological perspective I adopted throughout the entire work. The Romanian context, analized from a diachronic and a synchronic perspective represents the object of the second chapter. Some aspects of the Regime policies and other characteristics of the Romanian poscomunist period of “transition” are useful frameworks that become a background of the migration flows outside the country. The third chapter focuses on the Romanian patterns of migration. The reconstruction of some past attitudes that Romanians adopted towards migration are relevant in order to reveal the continuity with the present migratory practices. A consistent part is dedicated to a concrete example based on a field research in Bologna on a group of Romanian roma migrating from the south of Romania. The contact with these persons opened a debate on the limits between legal and illegal migration practices among the Romanians. The conclusion is that minors’ migration to Italy follows the adult patterns and flows. The nucleus of the field researches is included in the fourth and the fifth chapter. Before presenting the settings and the itineraries of the field researches, some deconstructive reflections are made on the representations that common sense and social sciences create on concepts as “child”, “minor” and “childhood”. A first perspective on the Romanian migrant minors emerges from a research concentrated on a group of roma teenagers engaged in Bologna in activities like windscreen washing, pocket-picking, begging and street prostitution. The aim of the research was to gain access to their daily life, to observe their relationship with the adults who “accompany” them and the strategies they activate in order to take some material profit out of their migratory experience. A parallel field research focuses on the Romanian minors who are part of the roma group coming from the south of Romania. Most of them are reunited with their family in Bologna, but according to the Italian law, they are all living as illegal migrants. Others are only temporary sheltered by these families and they meanwhile dedicate to illegal survviving practices. An interesting point of my participant observation was to reveal the motivations that these minors give when asked about the refusal to start a legal career inside the local Centres dedicated to the “non accompanied minors”. Their autoreflexivity brings some light on the controversy regarding the adequacy of the local and national care system and the migratory projects the minors have. In this respect, a small part of the research is dedicated to the phenomena of minors’ street prostitution in Bologna, as a useful contribution to the fragmented vision researchers have on the “unaccompanied” or “separated” children. The last chapter focuses on a decentered cooperation project that emerged as an alternative response the local administration from Bologna had chosen for facing the presence of numerous migrants coming from the south of Romania. The group of Romanian roma who was also the object of my field research became the starting point for the cooperation proposals between the city of Bologna and the city of Craiova. Although there are three projects involving the two administrations, throughout a period of stage in the Romanian city of Craiova I chose to analyse, only the one dedicated to the “urgent measures” requested in order to contrast the illegal migration and the trafficking in minors. This final part of the thesis highlightens the possible contribution that such a project might bring to the study of a complex and in some parts contradictory phenomena as that of the “unaccompanied” migrant minors.

Progettare l'ospitalità: turismi e turisti della città contemporanea

La ricerca si pone come obbiettivo principale quello di individuare gli strumenti in grado di controllare la qualità di una progettazione specifica che risponde alle forti richieste della domanda turistica di un territorio. Parte dalle più semplici teorie che inquadrano una costante condizione dell’uomo, “il VIAGGIARE”. La ricerca si pone come primo interrogativo quello definire una “dimensione” in cui le persone viaggiano, dove il concetto fisico di spazio dedicato alla vita si è spostato come e quanto si sposta la gente. Esiste una sorta di macroluogo (destinazione) che comprende tutti gli spazi dove la gente arriva e da cui spesso riparte. Pensare all'architettura dell’ospitalità significa indagare e comprendere come la casa non è più il solo luogo dove la gente abita. La ricerca affonda le proprie tesi sull’importanza dei “luoghi” appartenenti ad un territorio e come essi debbano riappropriarsi, attraverso un percorso progettuale, della loro più stretta vocazione attrattiva. Così come si sviluppa un’architettura dello stare, si manifesta un’architettura dello spostarsi e tali architetture si confondono e si integrano ad un territorio che per sua natura è esso stesso attrattivo. L’origine terminologica di nomadismo è passaggio necessario per la comprensione di una nuova dimensione architettonica legata a concetti quali mobilità e abitare. Si indaga pertanto all’interno della letteratura “diasporica”, in cui compaiono le prime configurazioni legate alla provvisorietà e alle costruzioni “erranti”. In sintesi, dopo aver posizionato e classificato il fenomeno turistico come nuova forma dell’abitare, senza il quale non si potrebbe svolgere una completa programmazione territoriale in quanto fenomeno oramai imprescindibile, la ricerca procede con l’individuazione di un ambito inteso come strumento di indagine sulle relazioni tra le diverse categorie e “tipologie” turistiche. La Riviera Romagnola è sicuramente molto famosa per la sua ospitalità e per le imponenti infrastrutture turistiche ma a livello industriale non è meno famosa per il porto di Ravenna che costituisce un punto di riferimento logistico per lo scambio di merci e materie prime via mare, oltre che essere, in tutta la sua estensione, caso di eccellenza. La provincia di Ravenna mette insieme tutti i fattori che servono a soddisfare le Total Leisure Experience, cioè esperienze di totale appagamento durante la vacanza. Quello che emerge dalle considerazioni svolte sul territorio ravennate è che il turista moderno non va più in cerca di una vacanza monotematica, in cui stare solo in spiaggia o occuparsi esclusivamente di monumenti e cultura. La richiesta è quella di un piacere procurato da una molteplicità di elementi. Pensiamo ad un distretto turistico dove l’offerta, oltre alla spiaggia o gli itinerari culturali, è anche occasione per fare sport o fitness, per rilassarsi in luoghi sereni, per gustare o acquistare cibi tipici e, allo stesso tempo, godere degli stessi servizi che una persona può avere a disposizione nella propria casa. Il percorso, finalizzato a definire un metodo di progettazione dell’ospitalità, parte dalla acquisizione delle esperienze nazionali ed internazionali avvenute negli ultimi dieci anni. La suddetta fase di ricerca “tipologica” si è conclusa in una valutazione critica che mette in evidenza punti di forza e punti di debolezza delle esperienze prese in esame. La conclusione di questa esplorazione ha prodotto una prima stesura degli “obbiettivi concettuali” legati alla elaborazione di un modello architettonico. Il progetto di ricerca in oggetto converge sul percorso tracciato dai Fiumi Uniti in Ravenna. Tale scelta consente di prendere in considerazione un parametro che mostri fattori di continuità tra costa e città, tra turismo balneare e turismo culturale, considerato quindi come potenziale strumento di connessione tra realtà spesso omologhe o complementari, in vista di una implementazione turistica che il progetto di ricerca ha come primo tra i suoi obiettivi. Il tema dell’architettura dell’ospitalità, che in questo caso si concretizza nell’idea di sperimentare l’ALBERGO DIFFUSO, è quello che permette di evidenziare al meglio la forma specifica della cultura locale, salvandone la vocazione universale. La proposta progettuale si articola in uno studio consequenziale ed organico in grado di promuovere una riflessione originale sul tema del modulo “abitativo” nei luoghi di prossimità delle emergenze territoriali di specifico interesse, attorno alle quali la crescente affluenza di un’utenza fortemente differenziata evidenzia la necessità di nodi singolari che si prestino a soddisfare una molteplicità di usi in contesti di grande pregio.

Survival of the fittest: Herausforderungen an den Fremdenverkehr im Zeichen des global change

Der Globale Wandel ist im Begriff, den Tourismus zu verändern. Die Wechselwirkung von Tourismus und Klimawandel sind beidseitiger Art. Die vorliegende Arbeit zeigt Möglichkeiten der Adaption und einen wandelbaren Fremdenverkehr. Eine Übersicht der gängigen Tourismusmodelle stellt den Stand der Forschung dar. Der Fremdenverkehr ist durch drei Faktoren massiv geprägt: Die Nachfrage und Motivation, die Reisemittler und Veranstalter sowie das Destinationsangebot. Bei der Motivation wirken Motiv und Anreiz Motivationspsychologisch betrachtet auf die Reiseentscheidung deren Grundlage verarbeitete Informationen sind. Reisemittler und Veranstalter haben einen großen Einfluss auf Entscheidungsprozesse. Neue IuK Technologien haben deren Arbeit grundlegend verändert. Das Tourismusangebot wird stark durch die naturräumlichen Gegebenheiten sowie das politische System bestimmt. Überlebenswichtig für die Destination ist die evolutionstheoretisch etrachtete Fitnessmaximierung also Adaption und Wandel, um sich an geänderte Rahmenbedingungen anpassen zu können. Gerade im Bereich des Klimawandels müssen Maßnahmen ergriffen werden. Aber auch die Marktsättigung gerade in Verbindung mit der aktuellen Finanzkrise wirkt besonders schwer auf die Destination. Eine hohes Innovationsvermögen, Trendscanning und der Zusammenschluss in flexiblen Netzwerkclustern können einen Kundenmehrwert erzeugen. Die Fitnessmaximierung ist somit Überlebensziel der Destination und führt zur Kundenzufriedenheit die im Sättigungsmarkt alleinig Wachstum generieren kann.

Entwicklung eines ökotouristischen Nutzungskonzeptes für den ehemaligen Militärstandort Hjerkinn Skytefelt im Nationalpark Dovrefjell-Sunndalsfjella in Mittel-Norwegen

Der Ökotourismus hat sich in den letzten Jahren zu einer Tourismussparte entwickelt, die nicht nur immer mehr Interessenten unter den Nutzern findet, sondern auch vielfältige Forschungsmöglichkeiten eröffnet.rnAus interdisziplinärer Betrachtungsweise kann man sowohl in den Gebieten der Biologie, der Wirtschaft, der Geographie, aber auch der Politik forschend tätig werden. rnDa der Tourismus in den letzten Jahren eine immer größere Bedeutung gerade für Länder mit weitestgehend intakten Naturressourcen erlangt hat, stellt sich die Frage inwieweit die Wirtschaft eines Landes auf diese Einnahmequelle angewiesen ist und ob nicht die ökologischen Belange immer weiter in den Hintergrund treten.rnAus diesem Ansatz heraus erfolgte zunächst eine qualitative und quantitative Bestandsaufnahme, die ein klares Bild vom derzeitigen Zustand in der Region ermöglicht. Darüber hinaus werden im Rahmen der Untersuchungen Zukunftsperspektiven aufgezeigt. Diese sollen verdeutlichen, inwieweit man steuernd in solche dynamischen Entwicklungsprozesse eingreifen kann oder soll.rnDie Schwerpunkte dieser Arbeit liegen in dem Bereich der Befragung von Touristen und in der Ausarbeitung eines digitalen Geländemodells zur späteren Nutzung in einem aufzubauenden Nationalpark-Infozentrum. Auf der Grundlage dieser Untersuchungen wurde ein touristisches Nutzungskonzept entwickelt und auf seine ökologischen Umsetzungschancen hin untersucht. Der Aspekt des Ökotourismus wird einleitend erörtert und definiert. Anschließend werden die Potenziale der norwegischen Tourismuswirtschaft untersucht. Die Befragungsergebnisse sowohl der norwegischen Besucher als auch der ausländischen Touristen werden in verschiedenen Korrelationen näher untersucht.rnEin gesonderter Bereich der Untersuchungen gilt dem Problemfeld des Wildcampings in Norwegen. Die dramatischen Entwicklungen der letzten Jahre rufen immer mehr Aktivisten auf den Plan. Da die Deutschen die größte Besuchergruppe darstellen, wurden innerhalb der Jahre 2003 bis 2006 Einzelinterviews geführt, um einen Überblick über das Übernachtungsverhalten der Deutschen in Norwegen gewinnen zu können. In den vergangenen 10 Jahren sind die deutschen Besucherzahlen in Norwegen leicht rückläufig, während die der Niederländer kontinuierlich steigen.rnAuf diesen Ergebnissen basierend wurden problemzentrierte Interviews mit Wohnmobilreisenden, der größten Gruppe der Individualreisenden, durchgeführt. rnMehr als 600.000 Nächte pro Jahr verbrachten die deutschen Wohnmobilreisenden außerhalb der Campingplätze, was ökologische und ökonomische Auswirkungen hat und nicht mehr mit dem in Norwegen geltenden „Allemansrett“, dem Jedermannsrecht, vereinbar ist. rnGerade die Touristen, die mit dem Wohnmobil reisen, können nur schwer mit anderen Reisenden verglichen werden, da sie mit einer völlig anderen Reiseauffassung mehr oder weniger autark unterwegs sind. Dabei legen sie besonders große Distanzen zurück und haben sich zum Ziel gesetzt, möglichst viel in kurzer Zeit zu sehen und zu erleben. Für alle Touristengruppen wurde untersucht, auf welchem Weg die Informationen für die geplante Reise beschafft wurden. Der Reiseführer ist der hauptsächliche Informationslieferant und ist teilweise für das Verhalten der Urlauber mitverantwortlich. Es konnte festgestellt werden, dass das Image des Landes und die Reisemotive das Reiseverhalten und die Wahrnehmung determinieren. Eine Untersuchung der so genannten Pull- und Push-Faktoren ergab, dass die nahezu noch unberührte Natur, die raue Landschaft sowie Ruhe und Erholung die entscheidenden Pull-Faktoren für Norwegenreisende sind. Dabei überprägt das Image Norwegens als „wildes Naturland“ die Wahrnehmung für verschiedene Problembereiche, die in Norwegen, wie auch in vielen anderen Ländern Europas, durchaus vorhanden sind. rnProblemfelder, wie Landschaftsausbeutung, Wildcamping, reduziertes Konsumverhalten und damit einhergehende rückläufige Besucherzahlen, können aber durch innovative Tourismuskonzepte und neue Reiseformen abgebaut werden. Hierbei sind Medien, wie Reiseführer, Internet und Reisemagazine, in die Pflicht zu nehmen.

Geomorphological and statistical analysis on Ravenna dune fields changes, based on Terrestrial Laser Technology

Coastal sand dunes represent a richness first of all in terms of defense from the sea storms waves and the saltwater ingression; moreover these morphological elements constitute an unique ecosystem of transition between the sea and the land environment. The research about dune system is a strong part of the coastal sciences, since the last century. Nowadays this branch have assumed even more importance for two reasons: on one side the born of brand new technologies, especially related to the Remote Sensing, have increased the researcher possibilities; on the other side the intense urbanization of these days have strongly limited the dune possibilities of development and fragmented what was remaining from the last century. This is particularly true in the Ravenna area, where the industrialization united to the touristic economy and an intense subsidence, have left only few dune ridges residual still active. In this work three different foredune ridges, along the Ravenna coast, have been studied with Laser Scanner technology. This research didn’t limit to analyze volume or spatial difference, but try also to find new ways and new features to monitor this environment. Moreover the author planned a series of test to validate data from Terrestrial Laser Scanner (TLS), with the additional aim of finalize a methodology to test 3D survey accuracy. Data acquired by TLS were then applied on one hand to test some brand new applications, such as Digital Shore Line Analysis System (DSAS) and Computational Fluid Dynamics (CFD), to prove their efficacy in this field; on the other hand the author used TLS data to find any correlation with meteorological indexes (Forcing Factors), linked to sea and wind (Fryberger's method) applying statistical tools, such as the Principal Component Analysis (PCA).

Nuove pratiche turistiche e sostenibilita'. I profili del turista lento in Valnerina

Il presente lavoro intende analizzare il tema del turista lento che nell’ultimo decennio si è diffuso nel dibattito scientifico e culturale connesso al tema della sostenibilità e della qualità della vita e nel contesto dell’approccio teorico strutturato intorno alle nuove tendenze dello Slow Tourism. In una prima parte la tesi delinea il framework della sostenibilità con particolare attenzione al recente dibattito in corso sulla “decrescita” e l’“a-crescita” come concetti alternativi al paradigma della crescita. Successivamente viene evidenziato il modo in cui le idee di base ed i principi dello sviluppo sostenibile sono stati applicati al turismo e indagato il legame tra sostenibilità e responsabilità e come questo configura l’emergere di un turismo “responsustable”. In tale contesto viene analizzata la relazione tra turismo e lentezza in cui a filosofia slow non deve essere interpretata come un fenomeno del momento o un innovativo prodotto turistico, ma come una filosofia di vita, un movimento sociale e globale che negli ultimi anni ha caratterizzato i diversi ambiti socio-economici delle comunità locali. Successivamente attraverso una review della letteratura nazionale ed internazionale sul tema, la pluralità di prospettive teoriche vengono sistematizzate in tre ipotesi di lettura riconducibili a tre paradigmi: sostenibilità- slow tourism- territorio; benessere – slow tourism – qualità della vita; esperienza – slow tourism – consumo. Nella seconda parte del lavoro viene presentata l’indagine empirica a partire dall’analisi di contesto del territorio in cui si è svolta l’attività di ricerca, i nove comuni del Comprensorio Turistico della Valnerina in Umbria, con particolare riferimento all’analisi dell’offerta e della domanda turistica. Successivamente sono presentati i risultati di un questionario somministrato a 620 turisti attraverso il quale viene analizzato il profilo motivazionale, le esperienze di fruizione turistica e la percezione della qualità territoriale da parte del turista e delineato il profilo del turista slow in Valnerina.

Eine ökologische Landeskunde der Rhön

Die Ökologische Landeskunde der Rhön – mit einem Schwerpunkt auf dem hessischen Teil – behandelt als moderne Landeskunde neben der Geostruktur und der humangeographischen Struktur im Besonderen die ökologische Struktur, denn nur durch diese Pointierung können Räume in ihrer Gesamtheit und Komplexität beschrieben werden. Das gilt im Besonderen für ökologisch bedeutsame Schutzräume wie die Rhön. Der Mittelgebirgsraum Rhön ist eine über Jahrhunderte gewachsene Kulturlandschaft mit einem weitgehend intakten, aber fragilen Ökosystem, das eine einzigartige und schützenswerte floristische und faunistische Ausstattung aufweist. Durch die weitreichenden mittelalterlichen Rodungen und die anschließende extensive Weidenutzung haben sich unter dem Eingriff des Menschen besonders auf den Höhenlagen im Laufe der Zeit artenreiche und ökologisch bedeutsame Ökosystemtypen, wie Borst- und Kalkmagerrasen, entwickelt. Um das naturräumliche und touristische Potential des Untersuchungsraums langfristig erhalten zu können, haben ökologische und nachhaltige Entwicklungen in den einzelnen Wirtschaftssektoren eine überragende Funktion. Im primären, sekundären und tertiären Sektor zeigen sich deutliche Entwicklungen hin zu ökologischen Erzeugnissen und Dienstleistungen. Der Ökolandbau gewinnt in der Rhön zunehmend an Bedeutung, Betriebe spezialisieren sich immer mehr auf Bio-zertifizierte und regionale Produkte und werben verstärkt mit ökologischen und rhöntypischen Begrifflichkeiten. Vor allem der für die Rhön wirtschaftlich bedeutende Tourismussektor, der im Spannungsfeld zwischen Ökonomie und Ökologie steht, entwickelt sich ebenfalls in Richtung nachhaltiger und umweltfreundlicher Formen. Am Beispiel des Milseburgradwegs konnte anhand einer Besucherbefragung auf Basis standardisierter Fragestellungen mit vornehmlich geschlossenen Fragen gezeigt werden, wie wichtig den Nutzern eine intakte Natur ist und wie Ökotourismus, Wirtschaftlichkeit und Naturschutz koexistieren können. Die Prämierung der Rhön zum Biosphärenreservat Rhön durch die UNESCO im Jahre 1991 erwies sich als Glücksfall und konnte dem strukturschwachen ländlichen Raum wichtige ökologische und wirtschaftliche Impulse geben, vor allem in Richtung ökologischer und nachhaltiger Erzeugnisse und Dienstleistungen. Die Auszeichnung kann dabei als Synthese zwischen Geostruktur und humangeographischer Struktur angesehen werden und ist Würdigung, Mahnung und Pflicht zugleich. Zusätzlich verdeutlicht sie auf eindringliche Weise die Fragilität und Schutzwürdigkeit des Ökosystems. Gegenwärtig zeichnen sich im Untersuchungsraum einige Entwicklungen ab, die die ökologische Raumstruktur gefährden und zusätzlich zur Aberkennung des Titels Biosphärenreservat führen könnten, weshalb sie kritisch gesehen werden müssen. Hier stechen der Bau der geplanten Bundesstraße B 87n von Fulda nach Meiningen oder das Kernzonendefizit hervor. Die Arbeit ist deshalb ein Plädoyer für den unbedingten Erhalt des identitätsstiftenden Titels Biosphärenreservat sowie für eine aktive Umweltbildung, denn eine erfolgreiche Zukunft und Identifikation der Bewohner mit ihrem Heimatraum ist unmittelbar an das Prädikat gekoppelt. Ökologische Landeskunden verstehen sich als aktive Elemente in der Umweltbildung und richten sich an die Menschen, die immer mehr zum prägenden Faktor von Räumen und ihren Ökosystemen werden. In der Rhön können sie sogar als Ausgangspunkt für die Herausbildung aufgefasst werden. Trotz der begrenzten Aussagekraft der Arbeit und der Komplexität des Untersuchungsraums zeigen sich vielfältige, ökologisch relevante Entwicklungen, die jedoch durch weitere sozialwissenschaftliche und wirtschaftswissenschaftliche Arbeiten erweitert, vertieft und stetig abgeglichen werden müssen.

Observations and modeling of the Marginal Ice Zone

Global climate change in recent decades has strongly influenced the Arctic generating pronounced warming accompanied by significant reduction of sea ice in seasonally ice-covered seas and a dramatic increase of open water regions exposed to wind [Stephenson et al., 2011]. By strongly scattering the wave energy, thick multiyear ice prevents swell from penetrating deeply into the Arctic pack ice. However, with the recent changes affecting Arctic sea ice, waves gain more energy from the extended fetch and can therefore penetrate further into the pack ice. Arctic sea ice also appears weaker during melt season, extending the transition zone between thick multi-year ice and the open ocean. This region is called the Marginal Ice Zone (MIZ). In the Arctic, the MIZ is mainly encountered in the marginal seas, such as the Nordic Seas, the Barents Sea, the Beaufort Sea and the Labrador Sea. Formed by numerous blocks of sea ice of various diameters (floes) the MIZ, under certain conditions, allows maritime transportation stimulating dreams of industrial and touristic exploitation of these regions and possibly allowing, in the next future, a maritime connection between the Atlantic and the Pacific. With the increasing human presence in the Arctic, waves pose security and safety issues. As marginal seas are targeted for oil and gas exploitation, understanding and predicting ocean waves and their effects on sea ice become crucial for structure design and for real time safety of operations. The juxtaposition of waves and sea ice represents a risk for personnel and equipment deployed on ice, and may complicate critical operations such as platform evacuations. The risk is difficult to evaluate because there are no long-term observations of waves in ice, swell events are difficult to predict from local conditions, ice breakup can occur on very short time-scales and wave-ice interactions are beyond the scope of current forecasting models [Liu and Mollo-Christensen, 1988,Marko, 2003]. In this thesis, a newly developed Waves in Ice Model (WIM) [Williams et al., 2013a,Williams et al., 2013b] and its related Ocean and Sea Ice model (OSIM) will be used to study the MIZ and the improvements of wave modeling in ice infested waters. The following work has been conducted in collaboration with the Nansen Environmental and Remote Sensing Center and within the SWARP project which aims to extend operational services supporting human activity in the Arctic by including forecast of waves in ice-covered seas, forecast of sea-ice in the presence of waves and remote sensing of both waves and sea ice conditions. The WIM will be included in the downstream forecasting services provided by Copernicus marine environment monitoring service.

Mobilities and Pottery Production Archaeological and Anthropological Perspectives

Our workshop aims at a deeper understanding of various itineraries of pottery and dif-ferent forms of human mobilities in which pottery is relevant, bringing together archae-ological and anthropological perspectives. For thousands of years, pottery has been an important part of many societies’ material culture and therefore a major research topic in both disciplines. In past and present societies the material existence of ceramic vessels is informed by various movements across time and space but also by periods of stasis: from the mo-ment of their production until their exclusion from daily practices, either disposed as waste, excluded as funerary objects or stored as collectibles. In their seemingly endless material durability, ceramic vessels might outlive their human producers, distributors or consumers and travel farther and longer. Still they are embedded in the regimes of human mobility, ranging from daily subsistence-based mobility to long-term migrations. In such processes, pottery shifts between spatial, temporal, social, economic and cultural contexts. Thereby ceramic vessels are appropriated and integrated in new contexts of action and meaning, sometimes leading to material transformations. This workshop takes place in the context of our archaeological research project „Mobili-ties, Entanglements and Transformations in Neolithic Societies on the Swiss Plateau (3900-3500 BC)“ to which our PhDs are connected. We address the above outlined topic by analysing the production of pottery. Based on dendrochronologically dated settle-ments between 3900 and 3500 BC, two regional pottery styles and their local variations are well known, Pfyn and Cortaillod. The vessels share the same habitus and were made of clays and temper deriving from the settlements’ surroundings. However, some vessels specific to other pottery styles are also present on the sites. They are characteristic for pottery styles known from more or less far off regions (Michelsberg, Munzingen or Néo-lithique Moyen Bourguignon). Some of them were travelling objects, as their non local raw materials show. Others seem to have been produced locally, pointing to long-term mobility and a change of residence from neighbouring social groups.

Capability of E-Bike Tourism in Switzerland

AIM OF PAPER AND RESEARCH QUESTIONS The primary aim of this investigation was to examine, if tourism in Switzerland can be stimulated by focusing on e-bike offers. Switzerland is an attractive and manifold country for bike tourism. However, there are plenty of hilly and steep areas, where the topography is quite demanding and cycling is predestined to ambitious sportsperson. Less performance-oriented bike tourists are possibly discouraged by the challenges of the landscape. E-bikes seem to be a reasonable alterna-tive to enable less trained person to attend bike tours in steeper regions as well as to keep heterogeneous groups together. E-bikes are already popular in Switzerland for daily routes as the journey to work, but they are not very common in the tour-istic context. The presented investigation evaluates the current standing of supply and demand for e-bike tourism and asks for opportunities and threats in the future development. LITERTURE REVIEW The existing frameworks to analyse capability in the field of sport tourism are limited, because of the broad variation of sports and tourism types. Still several conceptions are valuable to evaluate the opportunities of e-bike tourism in Switzer-land. According to Higham and Hinch (2009) the potential of touristic products and destinations always depends on the interaction among the factors place, people and activity. Standeven and de Knop (1999) support this position by identify-ing the experience of place as a key component of the sport tourism experience. Bull (2005) assumes that place not only affects experience. In his opinion, the specific spatially located resources are even crucial for the existence of nature sports. He identifies four factors determining the attraction of touristic products or destination, as physical characteristics, accessibility and infrastructural arrangements, political and economic resources as well as cultural and perceptual aspects. Concerning the demand side (people) the contemporary research is guided by an individual psychological focus delivering mainly results about motives and the decision making process (e.g. Görtz & Hürten, 2011). RESEARCH DESIGN AND DATA ANALYSIS The presented study is based on a between method triangulation, consisting of qualitative interviews with important stake-holders on the supply side and a cross sectional survey on the demand side. Qualitative interviews were conducted with the first provider of touristic e-bike routes and with the manager of the leading e-bike rental company in Switzerland. The interviews were evaluated by qualitative content analysis according to Mayring (2008). The survey covered a randomized sample of 748 adult persons and focused on interests and needs of potential consumers. The concluding potentials analy-sis combined the results of the interviews and the survey with the findings of literature research. As central outcome the strengths, weaknesses, opportunities and threats were evaluated and presented by SWOT-analysis. RESULTS Results showed that the development of e-bike tourism in Switzerland was not initiated by tourism promoter, but by an innovative e-bike producer. However, also for the manufacturer the fit between landscape (place), product (activity) and visitors (people) was the crucial criterion. The first e-bike tours were offered in a demanding and rural region, in order that the experience of place was able to promote a positive overall experience. Due to the success of the first touristic e-bike products, several tourism regions started to extend their portfolio with e-bike offers. To date a nationwide network for signalised e-bike tours, rental stations and changing stations for rechargeable batteries is established. Despite the attractive offer, the demand is only moderate. The obtained results of the consumer survey pointed at a certain barrier to use e-bikes for tourism activities. The most substantial barrier is the missing affinity for bike tourism in general. Another notable group considering themselves as “fit enough for normal bike tourism”. Nevertheless 55% of the respondent are interested in tour-istic e-bike products. Looking only at people with e-bike tourism experience, even 92% are interested in further activities. DISCUSSION AN CONCLUSION The current study findings are encouraging because they suggest a superior suitability and an attractive level of e-bike tourism products in Switzerland. The results of the consumer survey indicate an increasing demand for e-bike tourism. The investigation also points at some risks, as the rivalry for bike tourism or the raised safety hazard because of the increased driving speed. Summing up, the results support the conclusion, that e-bike tourism will become more important in the com-ing years. However, to reach the goal relevant trends as the requirement for customised offers must be considered and marketing activities are supposed to be extended. REFERENCES Bull, C. (2005).

Cálculo del valor ambiental de los jardines frontales urbanos : Mendoza (Argentina)

Los espacios verdes y, en general, la vegetación que cumple funciones estéticas y de protección ambiental son valorados, medidos y calculados por el área destinada al cultivo, en lugar de basar los cálculos en los elementos vegetales constitutivos. Esto significa una simplificación excesiva de la valoración de la vegetación (actual o proyectada) que no aporta criterios de cuantificación valorativa necesarios, actualmente, tanto para preservar vegetación existente como para políticas de desarrollo urbano y proyectos de ingeniería del mejoramiento ambiental. En el presente trabajo se propone aplicar a la valoración de los jardines frontales urbanos de la ciudad de Mendoza una metodología cuantitativa desarrollada por R. Codina et al., que se apoya en un concepto nuevo que es su influencia como mejoradores ambientales. La ecuación de cálculo se integra con índices de valoración como el Índice de Vegetación Ambientalmente Activa y el Índice Ambiental Urbanístico, que permiten cuantificar la importancia urbanística y ambiental de la vegetación. También se propone una base para implementar una política de incentivo de los jardines frontales mediante la disminución del avalúo valor terreno del impuesto inmobiliario, en una escala progresiva según el Índice Ambiental Urbanístico de cada propiedad, tendiente a la transformación de la ciudad en una ciudad-jardín, mejorando la calidad de vida y el atractivo turístico urbano.

Los recursos visuales en el ordenamiento territorial : I- Potrerillos (Mendoza, Argentina)

Se presenta la primera etapa del relevamiento de los recursos paisajísticos de la provincia de Mendoza, con el ajuste metodológico efectuado mediante una prueba piloto desarrollada sobre la Ruta Nac. N° 7, desde el Acceso sur en Luján de Cuyo (límite este) hasta Potrerillos inclusive (límite oeste). Los límites norte y sur están abarcados por el horizonte observable desde la ruta que atraviesa el área en sentido este-oeste. Se seleccionaron los puntos representativos mediante dos tipos de muestreo: sistemático y discrecional. En base a la catalogación de los recursos visuales se diseña una zonificación referencial general con miras al ordenamiento territorial y uso del suelo en distintas actividades de desarrollo futuro: turístico, reservas, residencial, agrícola, industrial. Se valora la calidad estética del paisaje aplicando, además, índices valorativos de la vulnerabilidad de los espacios a las actividades humanas (Índice de Naturalidad e Índice de Fragilidad), para obtener valores de la Calidad Visual Vulnerable del paisaje. Estos valores se grafican en planos que representan las distintas calidades alcanzadas y se complementa con una descripción de los puntos analizados, recomendaciones para el mejoramiento paisajístico a través de introducción o conducción de vegetación y fotografías documentales de las vistas analizadas.
