Should dispersers be fast learners? Modeling the role of cognition in dispersal syndromes.

2021

Abstract Both cognitive abilities and dispersal tendencies can vary strongly between individuals. Since cognitive abilities may help dealing with unknown circumstances, it is conceivable that dispersers may rely more heavily on learning abilities than residents. However, cognitive abilities are costly and leaving a familiar place might result in losing the advantage of having learned to deal with local conditions. Thus, individuals which invested in learning to cope with local conditions may be better off staying at their natal place. In order to disentangle the complex relationship between dispersal and learning abilities, we implemented individual‐based simulations. By allowing for develo…

Using the centre-periphery framework to explore human-carnivore relations

2023

Unidad de excelencia María de Maeztu CEX2019-000940-M Living alongside carnivores can incur both costs and benefits on people's lifeways. While positive outcomes of carnivore presence can foster coexistence, negative relations with carnivores can trigger carnivores' killing and undermine their conservation. In response to this, conservation efforts increasingly focus on promoting positive human-carnivore relations, most often through improvements in the flow of economic benefits from carnivores to local communities. However, there is a question mark over the effectiveness and potential consequences of market-based instruments for carnivore conservation. To understand the opportunities and p…

Biocultural conflicts: understanding complex interconnections between a traditional ceremony and threatened carnivores in north Kenya

2022

Abstract Biological and cultural diversity are inextricably linked and rapidly eroding worldwide. As a response, many conservation efforts foster synergies between cultural and biological diversity agendas through biocultural approaches. However, such approaches do not always address biocultural conflicts, where certain cultural practices can lead to biodiversity loss and, in turn, threaten the continuance of such practices. In this study, we examined a biocultural conflict in the Dimi ceremony, the most important rite of passage of the Daasanach agro-pastoralists of north Kenya, in which skins from threatened carnivore species are used extensively as traditional ornaments. We quantified th…

Tre Sicilie: nascita, distruzione e ri-ciclo dei paesaggi siciliani

2015

L’evoluzione delle politiche sul paesaggio in Sicilia vive una sorta di tripartizione sia storica che geografica: paesaggi tutelati e iper-protetti, paesaggi in trasformazione e paesaggi in recupero si susseguono evolutivamente nella storia dell’Isola, ma si giustappongono anche fisicamente nella contemporaneità. Questa realtà è oggetto di questo contributo che indaga evoluzione ed esiti di creazione, trasformazione e riciclo di paesaggi in alcuni territori esemplari della Sicilia, con l’obiettivo di analizzare, selezionare e proporre buone (o cattive) pratiche nell’ambito della ri-generazione dei paesaggi. Il contributo in forma di cronistoria fortemente selettiva di alcuni fenomeni che ha…

A Scan-to-BIM Approach for the Management of Two Arab-Norman Churches in Palermo (Italy)

2023

The paper shows the results of the research activities carried out by the Department of Engineering at the University of Palermo (Italy), which assessed the application of the Heritage Building Information Modelling (HBIM) methodology through a Scan-to-BIM approach to two local churches belonging to the medieval period. This project was motivated by a renewed interest from the city administrators towards the conservation of cultural heritage dating back to the Arab-Norman domination in Sicily since one of the two buildings was included in the UNESCO World Heritage Sites list in 2015. The morpho-typological style of the churches has been acquired by high-detailed 3D surveys, which provided t…

FROM SFM TO 3D PRINT: AUTOMATED WORKFLOW ADDRESSED TO PRACTITIONER AIMED AT THE CONSERVATION AND RESTAURATION

2017

Abstract. In In the last years there has been an increasing use of digital techniques for conservation and restoration purposes. Among these, a very dominant rule is played by the use of digital photogrammetry packages (Agisoft Photoscan, 3D Zephir) which allow to obtain in few steps 3D textured models of real objects. Combined with digital documentation technologies digital fabrication technologies can be employed in a variety of ways to assist in heritage documentation, conservation and dissemination. This paper will give to practitioners an overview on the state of the art available technologies and a feasible workflow for optimizing point cloud and polygon mesh datasets for the purpose …

TOWARDS AN ADVANCED CONSERVATION STRATEGY: A STRUCTURED DATABASE for SHARING 3D DOCUMENTATION between EXPERT USERS

2019

Abstract. Nowadays, the researchers in Cultural Heritage fields investigate more and more about advanced conservation strategies that comprehend the possibility to share and use 3D models and structured information related to them. One of the modern method adopted to achieve this goal is to use structured web-platform. These are online systems that can handle data, created to contain and support precise information. They simultaneously respond to the need for a common ground for different expert users and of a unique tool where to store several kinds of data, coming from heterogeneous sources. The article aims to show how it is possible to build a valid tool for the conservation and monitor…

COMPUTER AIDED RESTORATION TOOLS TO ASSIST THE CONSERVATION OF AN ANCIENT SCULPTURE. THE COLOSSAL STATUE OF ZEUS ENTHRONED

2017

Abstract. The research focuses on the contribution of the integrated application of Computer Aided Restoration digital procedures as a means to guide the integration measure of an artifact, innovating and implementing the traditional investigation methods. The aim of the study was to provide effective geometrical-formal investigation tools in the frame of the conservation work of Zeus enthroned from Soluntum, conserved in the Archaeological Museum “A. Salinas” of Palermo. The paper describes the workflow of the 3D acquisition and graphical modeling with non-invasive digitalization and high information density techniques to assist the conservation of the legs of the throne, especially the in…

A RESTORATION ORIENTED HBIM SYSTEM FOR CULTURAL HERITAGE DOCUMENTATION: THE CASE STUDY OF PARMA CATHEDRAL

2018

Abstract. The need to safeguard and preserve Cultural Heritage (CH) is increasing and especially in Italy, where the amount of historical buildings is considerable, having efficient and standardized processes of CH management and conservation becomes strategic. At the time being, there are no tools capable of fulfilling all the specific functions required by Cultural Heritage documentation and, due to the complexity of historical assets, there are no solution as flexible and customizable as CH specific needs require. Nevertheless, BIM methodology can represent the most effective solution, on condition that proper methodologies, tools and functions are made available. The paper describes an …
