Caratteri adattivi della resilienza : la sperimentazione di Tangible Media Group e la progettazione adattiva per le crisi del futuro
No full textThe Adaptive Characters of Resilience Designing adaptive and resilient architecture could constitute an opportunity to re-think the immovable architectural characters, above all the firmitas, and to define a new paradigm of resilient adaptivity. Defining an adaptive methodology means being able to go beyond the actual strategies, which focus on technological solutions or social policies. The aim of this paper is to illustrate a different scenario for the near future design by introducing the vision-based design approach of the Tangible Media Group, and specifically
three of their latest prototypes, which merge the physicality of the real-world with the flexibility of the natural and digital environment
Il corpo fisico dell'architettura interattiva : approcci scenario-based e generativo
No full textLa complessità della realtà, insieme fisica e virtuale, nella quale siamo immersi richiede una riflessione su come realizzare una integrazione tra il mondo del digitale e l’architettura contemporanea. In particolare, l’articolo intende esplorare il modo in cui le informazioni virtuali possano divenire materie progettuali, intervenendo anche sui caratteri spaziali e formali del costruito. Pertanto si tratteranno due diversi approcci nelle architetture interattive, uno scenario-based e un altro generativo, capaci di stabilire i confini fisici della relazione tra architettura e informazioni. Jade Eco Park, Translated Geometries e One Ocean Pavilion offrono una diversa chiave di lettura del rapporto tra uomo, edificio e ambiente circostante, in una relazione meta-testuale tra fisico e virtuale che richiama
l’architettura contemporanea a una riflessione sulle potenzialità di questo fenomeno.The complexity of reality, both physical and virtual, in which we are immersed requires a reflection on how to achieve integration between the digital world and contemporary architecture. In particular, the article intends to explore the way in which virtual information can become design material, also intervening on the spatial and formal characteristics of the built environment. Therefore, two different approaches in interactive architectures will be discussed, one scenario-based and the other generative, capable of establishing the physical boundaries of the relationship between architecture and information. Jade Eco Park, Translated Geometries and One Ocean Pavilion offer a different key to interpreting the relationship between man, building and surrounding environment, in a meta-textual relationship between the physical and the virtual that calls contemporary architecture to reflect on the potential of this phenomenon
The role of natural complexity in adaptive architecture : Eco-based design: Nature as pattern and architecture element
No full textIn the broader context of an ongoing doctoral research, it is possible to consider adaptive architecture as a possible solution for designing resilience. Despite the large use of technology, it is possible in fact to recognise different design approaches that involve Nature in the whole process, from the initial conceptual phase toward the effective construction stage. Among these different ways, which underline a biomorphic common perspective, this paper would focus on two of them, underlying the role of nature in the design approach. The first is referred to the consideration of Nature as a design material and is shown through the projects of the American architectural firm SCAPE, ‘Living breakwaters’ and ‘Oystertecture’. The second approach instead will introduce the use of natural pattern as a way to conceive architecture through geometries, as shown in ‘Hygroscope’ and ‘Pad Hygroskin’, two projects conceived within the Institute for Computational Design, University of Stuttgart. The aim of the paper is to show different vision of the More-than-human approach in architecture, envisioning a more responsible way to think of the built environment through Nature to design resilience
La Sicilia dei centri minori: Above the clouds nella Valle di Bolognetta : architettura, arti performative e nuovi immaginari
No full textIl lavoro elaborato dal Gruppo di ricerca LabCity Architecture sulla rigenerazione dei piccoli centri rurali del territorio siciliano, vittime della crisi economica e demografica di quest’ultimo decennio, evidenzia l’urgenza di un ripensamento delle strategie di intervento in questi luoghi con forti potenzialità territoriali, patrimoniali e culturali, proponendo progetti di ricerca-azione in sinergia con le comunità locali coinvolte. La recente emergenza sanitaria causata dalla pandemia da Covid-19 ha evidenziato l’esigenza di una ricerca mirata ad individuare i caratteri e le esigenze specifiche soprattutto dei centri minori, destinatari di politiche e di interventi spesso inadeguati. In quest’ottica si inserisce il progetto Above the clouds, elaborato nel 2021 dal LabCity Architecture in occasione della Winter School “Cinema Paradise” nel territorio naturale della cascata di San Nicola nella Valle di Bolognetta, nell’area metropolitana di Palermo.LabCity Architecture group researches on the topic of regeneration of small rural centers in Sicily, victims of the economic and demographic crisis of the last decade. It highlights the urgency of rethinking new strategies in such places with strong territorial, heritage and cultural potential, and has suggested research-action projects in synergy with the local communities involved. The recent health emergency caused by the Covid-19 pandemic has highlighted the need for research aimed at identifying the specific characteristics and needs, especially of smaller towns, often the recipients of inadequate policies and interventions. In this perspective fits the project ‘Above the clouds’, developed in 2021 by LabCity Architecture on the occasion of the Winter School "Cinema Paradise" in the natural territory of the waterfall of San Nicola in the Valley of Bolognetta, in the metropolitan area of Palermo
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Genetic population structure of Epinephelus marginatus (Pisces, Serranidae) revealed by two molecular markers
No full textIn this paper, data are presented regarding the population structure of dusky grouper (Epinephelus marginatus) which was sampled in the Mediterranean Sea and Atlantic Ocean using two different molecular markers, ND2 RFLP and cytochrome b (cyt b) sequence analysis. The main objective of the study is to analyse the genetic variability of E. marginatus in the Mediterranean Sea to define how the biological characteristics of the species, such as the dispersal capability of pelagic larvae and the benthonic-sedentary life style, can affect the genetic population structure or maintaining the gene flow or determining genetic differences. Furthermore, we considered an Atlantic sample to establish the presence of genetic differences between the two biogeographical areas under consideration. Analysis of variation based on ND2 RFLP analysis revealed a genetic difference between the Atlantic and Mediterranean samples, whilst cyt b sequence analysis did not. There exists evidence for genetic differentiation for both molecular markers in the Mediterranean region. The majority of the variation was due to the Ustica Island sample and this could be due to differences in fisheries effort since the island is a protected area where recreational and professional fisheries are almost completely forbidden. The pattern of genetic diversity, haplotype networks and mismatch distribution suggest a historical influence on the genetic structure of E. marginatus and recent population expansion. An analysis of the genetic structure of the dusky grouper will be the prerequisite for decisions regarding conservation and fisheries management
Concern about the spread of the invader seaweed Caulerpa taxifolia var. distichophylla(Chlorophyta: Caulerpales) to the Western Mediterranean
No full textThe Australian alien seaweed Caulerpa taxifolia var. distichophylla, after being established along the Turkish Mediterranean coast in 2006, was recorded in Southern Sicily in 2007. Since then local fishermen asked for support to counteract the effects of entanglement of large amounts of the alien strain wrack in their trammel nets, causing the gear to become ineffective. The further northward and westward spread of this new alien strain is believed to be limited by winter temperature. We present novel data confirming that the new alien strain is fully naturalized in the Central Mediterranean and is expanding its range beyond such limit (i.e. the 15°C February isotherm), thus becoming potentially able to colonize the western basin. Based on a preliminary estimation of the effects on native polychaete assemblages, and considering some peculiarities of Sicily (mostly linked to its geographical position in the Mediterranean Sea), the risk linked to the increasing range of distribution of the invasive algae is highlighted
Rehabilitation, using prosthetic implants, in patients with cancer of the oral cavity [Riabilitazione implanto protesica in pazienti trattati per neoplasia del cavo orale.]
No full textBACKGROUND: The number of patients treated for neoplasms of the oral cavity (by surgery and/or radiotherapy) requiring prosthesis rehabilitation using osteointegrated implants is increasing greatly. The objective of this research is to examine the correlation between prosthesis rehabilitation using osteointegrated implants, radiotherapy and the use of hyperbaric oxygen treatment in order to reduce the risk of osteoradionecrosis. METHODS: Research was carried out on 13 patients with 58 implants. The patients were divided into three sample groups: group A patients underwent radiotherapy (10 implants), group B patients did not undergo radiotherapy (29 implants) and group C patients first underwent radiotherapy and then hyperbaric oxygen treatment (19 implants). The group C patients first underwent hyperbaric oxygen treatment at 2.5 atmospheres. The osteointegrated implants were then applied and hyperbaric oxygen treatment was carried out again over 20-30 postoperative sittings without any other treatment between the sittings. The whole test period lasted 24 months. RESULTS: Only two implants were lost out of the 58 implants and they were in the group that had undergone radiotherapy. CONCLUSIONS: The results show how pre and postoperative hyperbaric oxygen treatment improves the success rate of osteointegrated implants in mandibular areas that had previously undergone radiotherapy. Moreover, the stability of the prostheses that are fixed to the implants is greatly improved compared to conventional methods
