Reverse Modelling Process to support of a Flemish Wooden Altarpiece Physical Restoration

2021

This study focuses on digital Computer Aided Restoration procedures to guide the complex physical restoration of an artwork, innovating and implementing traditional survey methods. As a case study some results are presented of a complex and articulated conservative restoration project on a sculpted and painted wing altar, preserved in the Regional Gallery of Sicily in Palazzo Abatellis, Palermo. The application of non-invasive and high information density 3D survey methodologies allowed to record and integrate into a unique digital platform (designed within the UnReal Engine) a wide quantity of heterogeneous data which document the work's state (diagnostic analyses, graphical annotation, hi…

Ancora sulle "esplosive palatali" nelle inchieste dell'Atlante Linguistico del Mediterraneo (ALM): i punti albanesi

2021

Tra i «Problemi redazionali» emersi in fase di controllo e organizzazione dei materiali giunti dalla campagna di rilevamenti dell’Atlante Linguistico del Mediterraneo (ALM), Berruto (1971-1973) rileva la proliferazione e l’eterogeneità di alcune scelte grafemiche operate da diversi raccoglitori che, impegnati in una trascrizione più o meno puntuale delle risposte ottenute, avevano interpretato e risolto variamente alcune delle indicazioni previste nel sistema di trascrizione fonetica che accompagnava il Questionario. Particolarmente complesso era emerso il quadro relativo alla trascrizione di alcune consonanti del settore “palatale”, per le quali i grafemi (e i foni a essi corrispondenti) p…

Settore L-FIL-LET/12 - Linguistica ItalianaAmong the «Editorial problems» that emerged during the control and organization of the materials coming from the survey campaign of the Atlante Linguistico del Mediterraneo (ALM) Berruto (1971-1973) notes the proliferation and heterogeneity of some graphemic choices made by different field researchers. As they were engaged in a more or less punctual transcription of the answers obtained they had interpreted and solved differently some of the directions provided in the phonetic transcription system that accompanied the Questionnaire. The picture relating to the transcription of some consonants of the palatal sector had emerged as particularly complex since the graphemes (and the corresponding phones) foreseen in the original system (ALM 1959) were insufficient. Not even the 1971 updates meant to improve the representation of some phonetic features emerged from the investigations in the operations of Response reviewing allowed to obtain a clear homogeneous picture regarding the «plosive palatal» consonants. With regard to the phonetic trait under scrutiny I have already had the opportunity to propose a path aiming to the achievement of possible operational solutions. This has taken place in view of the planned simplification / homologation and transcoding phase from the ALM original system to the IPA one - while proceeding from the examination of the Schedoni’s current state with regard to the surveys referring to central-southern Italy Corsica and Sicily (see Matranga 2019). The scope is now to investigate the same phonetic trait as proven in the materials about the surveys carried out by Lirak Dodbiba in the ALM’s three Albanian points.

Lupi e licotoponimi in Sicilia: un confronto interdisciplinare

2019

ABSTRACT. (Wolves and wolf place names in Sicily: an interdisciplinary comparison). Starting from zoological and onomastic aspects, the paper aims at comparing data demonstrating the presence of wolves in Sicily. Apart from the review offered by LA MANTIA & CANNELLA (2008) and the study on Minà Palumbo’s works (GENCHI 2012), further sources prove the presence of wolves in Sicily, in particular in the Madonie area. The integration of these data with those concerning ethno-linguistic and toponymic aspects, even without the support of other scientific works, allows to verify the distribution of this predator in Sicily as well as its presence in Sicilian cultural imagery.

Social networks and social activities promote cognitive functioning in both concurrent and prospective time: evidence from the SHARE survey

2018

The study aimed to investigate the role of social activities, social networks as well as socioeconomic status (SES) in influencing some aspects of cognitive functioning (immediate and delayed verbal recall tests and semantic verbal fluency) in elderly people over time. This analysis was conducted on a sample of 31,954 healthy elderly people (58% female, mean age 65.54 ± 9.74) interviewed in both the fourth and sixth waves of the Survey on Health, Aging and Retirement in Europe (SHARE), in 2011 and 2015. A structural equation model with measurement component was used to assess the relationship between cognitive function, social life and SES over time. Multilevel ordinal logistic regression w…

Design and analysis of discrete choice experiments for models with response time

2013

Settore SECS-S/02 - Statistica Per La Ricerca Sperimentale E TecnologicaA sector of conjoint analysis (experimental design in marketing research) is made of the so called choice experiments. In choice experiments respondents undergo a questionnaire which is nowadays mostly submitted through the internet. The questionnaire proposes to the respondent a sequence of choice sets each one including two or more profiles being a profile a specific combination of attribute levels. The respondent selects the preferred profile for each choice set. Responses given by a sample of respondents are analysed through suitable methods aimed to eventually find the best combination of attribute levels. One method of analysis adopts the Multinomial Logit (MLN) model. In this article the authors show the results of the MLN analysis compared with another model of analysis which uses an additional response which can be easily recorded by electronically submitted questionnaires. In practice modern survey platforms like “Qualtrics” (the one used for this work) can record the so called “response latency” i.e. the time taken by the respondent to make the choice and select the most preferred profile in the choice set. Thanks to a response latency model further refined in this work it is possible to deduce the relative weight of importance of the profiles for each choice set and respondent. This type of response can be used in place of the dichotomous choice variable in the MLN model. The two models and methods of analysis are deeply compared and it is critically discussed when it is better to use one or the other method. As a result a more reliable estimate of the optimal profile comes up implying lower risks for new investments and marketing decisions.

Prioritisation of alternatives with analytical hierarchy process plus response latency and web surveys

2014

This paper introduces a new method that combines the well-known analytical hierarchy process (AHP) with a response latency metric. The response latency is the time taken by respondents to make choices over pairwise comparisons. The analytical calculation of relative importance weights of the alternatives is made by using a response latency model previously validated in several case studies. This combination aims to overcome some drawbacks of the traditional AHP related to the use of a rating scale (the so-called Saaty scale), and it is a natural way to involve response latency in established decisionmaking methods. This new method can be profitably adopted in web surveys where it is easy to…

A Proposal to estimate the roaming–dog Total in an urban area through a PPSWOR spatial sampling with sample size greater than two

2018

Settore SECS-S/05 - Statistica SocialeDogs roaming in urban areas constitute an issue for public order hygiene and health. Proper planning of actions for health and security control and allocation of financial funds require the knowledge of the roaming–dog–population size in a given urban area. Unfortunately a reliable statistical procedure aimed to measure such population is not available yet in literature. This paper presents a simple reproducible survey sampling procedure to estimate the number of roaming dogs in an urban area through the description of a real study carried out on a restricted area of the city of Palermo in southern Italy. A sample of areas is drawn by means of a drawn–by–drawn spatial sampling with probabilities proportional to size and without replacement (PPSWOR). As inclusion probabilities are not available in closed form they are estimated by Monte Carlo approach which is of simple implementation and permits design–based variance estimation even when first–order inclusion probabilities are unknown.

Fluttuazioni commerciali tra Nord Africa e Sicilia meridionale: il VI e il VII secolo. Cignana come caso studio

2021

This essay will examine the trend in imports of African potteries – notably amphorae and fine wares – in a rural zone of southern Sicily. We are dealing with the region of Cignana, not far from the coastline, where archaeological excavations documented a large settlement that experienced a big growth between the 5th and 6th centuries AD. During this period, a shift in the ceramic supply from the Zeugitana towards the Byzacena occurred. Nevertheless, the positive trend in imports persists until the last decades of the 6th century. Thereafter, it shows a decrease until the apparent interruption after the mid-7th century. New changes in the Mediterranean trading system seem to undermine the pr…
