The public archaeology as a research and action process for sustainable enhancement
No full textIn order to guarantee conditions for a "lasting, inclusive and sustainable economic growth" based on the development of tourism, there is the necessity to evaluate a strategy taking into account not only the economic and environmental implications, but also the socio-cultural ones. This means undertaking a process of research and actions, that at first must bring the community closer to the heritage by developing a sense of belonging and care, then have to make people aware of both the cultural and economic potential of cultural heritage. Communicating research results, the community participation, the training are some of the key actions required coming from the "public archeology" and aiming at developing a relationship with citizens, and that have been for years the focus of ICVBC's research and actions
Roma Caput Aquae: un rapporto di lunga durata tra la città e il territorio
No full textL’Acqua Marcia è uno degli acquedotti dell’antichità romana che ha il rapporto più longevo con Roma. Infatti, ripercorrere le tappe della sua costruzione, trasformazione, interruzione e rivitalizzazione, significa ripercorre la storia stessa dell’Urbe e di parte del territorio laziale. Sull’acquedotto esiste una lunga tradizione di studi, dall’antichità a oggi, che hanno consentito di ricostruirne, con buona approssimazione, il percorso antico dalle sorgenti fino all’interno della città imperiale, di identificare le diramazioni di volta in volta aggiuntesi e le destinazioni finali della sua acqua. Inoltre, sul territorio regionale e nell’Urbe sono ancora evidenti gli imponenti resti dell’acquedotto, dalle singole componenti architettoniche (spechi, ponti, arcate) ai monumenti sorti per lo sfruttamento dell’acqua (ville, terme, ecc.). Ad essi si aggiunge un ricchissimo patrimonio di documenti storici scritti e iconografici, epigrafici e archeologici, conservati in vari archivi e musei, che contribuiscono a comprendere la straordinaria importanza dell’Acquedotto. Il contributo presenta il lavoro di ricerca e analisi svolto sull'acquedotto nell'ambito del progetto europeo Water Shapes

Organic-inorganic composite materials have been extensively studied for a long time, since they combine advantages of the inorganic material (i.e. rigidity, thermal stability) and of the organic phase, which is, in most of cases, a polymer (i.e. flexibility, ductility and processability (1).
Among several organic/inorganic hybrid materials, the polymer/silica nano- and meso-composites are the most commonly reported in literature and have attracted both academic and industrial interests. Besides the common applications, including coating, catalysts, devices and sensors, this type of composites can be also employed to realize innovative construction materials (2).
Here we report a formulation from renewable sources of a novel thermal- insulating material, able to offer an eco-friendly alternative to the conventional light-weighed synthetic products. The designed material is an organic-inorganic composite of lignosulfonate, as the main waste product of cellulose-production, dispersed into a silicate matrix with the addition of non-food corn starch, acting as gluing agent. The further addition of esterification promoters, foaming and coupling agents, polyol acids as pH-regulators, fungi preservatives and Kenaf fibers as reinforcing agents, confers the tailored targeted features. Addition of a suitable coupling agent (APTES) promotes linkage between the polyol groups of glycerol or the surfactant lignosulfonate with silanol and siloxane moieties of the silicate substrate. The resulting blended biopolymers-microporous silica material (40m) appears as a single phase rigid foam, which conjugates low-density (0.25-0.35g/cm3), low conductivity (λ= 0.02-0.05 W/m2K) and acceptable mechanical properties (3). These features make the composite useful for bored-brick filler or as small insulating panels in building applications. Recent efforts to reduce hydrophilicity and then biodegradability by starch acetylation and to introduce benign polycarboxylic acids as alternative expanding promoters, more efficient plasticizers or foam stabilizers and rheology modifiers, will be also presented.

Mindscapes: Laura Riding's poetry and poetics /
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão.Esta tese propõe uma leitura revisionista da poesia contemporânea através do exame do caso de um dos mais esquecidos escritores norte-americanos do século XX: Laura (Riding) Jackson (1901-1991). O objetivo é demonstrar que Riding não apenas possuía uma poética definida e singular, mas que ela permanece uma das instâncias mais extremas e paradoxais do modernismo anglo-americano, a ponto de Riding abandonar a escrita da poesia em 1938. Recorrendo a conceitos de "formação do cânone" bem como às noções de "discurso" e "função do autor", em Foucault, investigo a construção do cânone da poesia moderna anglo-americana, recuperando o contexto e as circunstâncias da ocultação de Riding. Enquanto cubro os "discursos" poéticos em circulação na primeira metade do século XX-o "imagismo" de Pound, a "dissociação da sensibilidade", "impersonalidade" e "tradição" de Eliot, a "unidade orgância" e "ambigüidade" da Nova Crítica-ofereço um panorama crítico de modernismos alternativos sendo articulados à época. Minha intenção é demonstrar que os poemas de Riding são expressões vigorosas de um escritor para quem "a mente pensando se torna a força ativa do poema", para usar a apta formulação de Charles Bernstein. Entre minhas descobertas sobre as várias e complexas razões que levaram à não-canonização de Riding estão a hegemonia da Nova Crítica, o exílio voluntário de Riding da cena literária (onde são feitas ou desfeitas as reputações), sua recusa em ser antologiada, bem como em ser explicada em termos críticos que não os dela. Todos esses fatores, mais a "dificuldade" de sua poesia, contribuíram para fazer de Riding "a maior poeta esquecida da poesia norte-americana", como escreveu Kenneth Rexroth. Ajudado pelos insights de dois importantes críticos de poesia norte-americana, Charles Bernstein e Marjorie Perloff, defendo que a "poesia da mente" de Riding-onde o que está em jogo é que o que pensamos ser a nossa realidade-representa uma mudança radical no paradigma da poética modernista: de uma poesia centrada na imagem para uma poesia centrada na linguagem. Focalizando a experiência consciente e o tempo duracional do pensamento presente em seus poemas, concluo que as "pensagens" de Riding têm o objetivo preciso de constatar um fato universal: enquanto seres humanos e pensantes, estamos numa condição permanente chamada linguagem

Heritage tourism: a case study of the Laura Ingalls Wilder Heritage Site at Pepin, Wisconsin
No full textPlan BMany things must be taken into consideration when developing a heritage tourism site. It can be a wonderful opportunity for the community involved to benefit economically and historically. Heritage tourism can keep alive the heritage and traditions of the communities past. When it is discovered that a heritage site exists, the first step is to consult with the community. A site will not succeed without the acceptance and assistance from the community involved. Once the interest is known, the development process can proceed. After determining that there is a heritage tourism site possibility in their area, a commumity must do research to determine the feasibility of the site, what will make it a success, and how to obtain that success. This study will examine a community with a heritage tourism site that has been successful in developing and maintaining it's site. By conducting this study, other communities seeking information for developing their site will have an example and tool to work with. The site chosen for this study is the Laura Ingalls Wilder site in Pepin, Wisconsin. The town is rich with it's heritage associated with Laura Ingalls Wilder. The development and success for this town will be documented through this study. Laura Ingails Wilder is a perfect choice for examining heritage tourism. The author of many American Pioneer books, she has become famous all over the world. In turn all places that she or her family members lived are or are becoming heritage tourism sites. There are older ones that have been in progress for some years, such as the one in Pepin, and there are ones that are being discovered through the popularity of new books written about Laura's family. These communities would benefi greatly from the information this study will produce. Without the bene-fit of this knowledge communities who are unaccustomed to tourism or the way the other Laura Ingalls Wilder sites operate, may make terrible errors in development, tarnishing the site. This may also reflect badly on the other Laura Ingalls Wilder sites. It is important for new Wilder sites to examine all information and know exactly what they are doing when developing the site. If all the Laura Ingalls Wilder sites can benefit from each other's knowledge and experience it will greatly increase the market for all sites. The more detailed and expansive the sites are about their knowledge and sites to see, the more people are going to want to travel to as many sites as possible, learning all they can about the life of Laura Ingalls Wilder and her family. These sites not only attract Laura Ingalls Wilder fans but all people that are interested in the American Pioneer period of the United States history. This study will provide the knowledge for communities who are developing heritage tourism sites, especially those focusing on Laura Ingalls Wilder. This is a very important study for tourism and especially heritage tourism. When a heritage site is discovered communities run into the barrier of not having the experience and knowledge to develop the site properly. This study will analyze tourism in Pepin, Wisconsin to determine it's successfulness due to the fact that it is a Laura Ingalls Wilder heritage tourism site, and Wfit was developed in a way to provide tourists with a view of Laura Ingalls Wilder's past and the past of many Pioneer Americans. By studying this subject it will allow for many people to benefit. Tourist who are seeking the pleasure of the knowledge of the past, and communities who want to preserve their past and profit from tourism

Capire il territorio: paesaggio, agricoltura e tutela ambientale in penisola sorrentina.
No full textAbstract.
The Lattari mountains and the territory of the Sorrento-Amalfi peninsula constitute a very steep mountain structure with a high hydrogeological risk. This physical structure was determinant for the genesis of the climate and the development of biotopes. In a similar way, it has conditioned the development of the human community by the affirmation of autarchic economies and a very varied and rich agriculture. Unfortunately, in recent times, the abandonment of niche agricultural practices risks not only causing the loss of a traditional economy but also damaging the landscape and geological stability. Only new policies for the protection of ancient crops will be able to guarantee a balanced and sustainable future for the peninsula
