Ranking services for students via preference elicitation at Padua university
Luigi Fabbris,Giovanna Boccuzzo,Cristiano Vanin
Electronic Journal of Applied Statistical Analysis : Decision Support Systems and Services Evaluation , 2011,
Abstract: The University of Padua conducted a survey to elicit the preferences of its students for new services that the university, the city and local authorities could offer to improve student life before, during and after graduation. In this paper, we present the statistical methodology for ranking services according to students’ preferences and discuss the resulting ranks of the services grouped in 10 thematic areas. We conclude that the preference elicitation method and the rank estimation method adopted in our research are appropriate for within-university prioritisation of student services.

Abstract: a new species of pacholenus schoenherr from southeastern brazil (coleoptera, curculionidae, molytinae), and new occurrences of species of the genus. pacholenus monteiroi sp. nov. (type-locality brazil, rio de janeiro state, carapebus, parque nacional da restinga de jurubatiba) is described and illustrated. the weevil develops as a stem gall-former in calyptranthes brasiliensis spreng (myrtaceae). the new species is easily distinguished from the other five known of the genus by the presence of a prominent supra-ocular ridge. an updated key for identification for all species of pacholenus is provided. three species of pacholenus are presently recorded for the states of rio de janeiro and s?o paulo; p. pelliceus and p. monteiroi occur in both states, while p. penicillus is only known from rio de janeiro; p. hispidus occurs in s?o paulo, being the most widespread species of the genus, ranging from minas gerais south to santa catarina.

Abstract: Relevance Theory, by Sperber & Wilson (1995), is a model of human communication and cognition which intend to explain how information is represented in an individual’s mind and how it is processed in an inferencial way in a communicative act. In this essay, only one aspect of the theory will be applied: the context selection. The formation and choice of the context – a subset of the hearer’s assumptions about the world – will be demonstrated through the movie Twelve Angry Men, in order to exemplify how the individuals process the assumptions about an information and how they select a context, among others, to interpret utterances during a communicative act.
Considera es relevantes sobre defini es de ‘comunidade de fala’ = Relevant considerations concerning some definitions of “speech community”
Aline Aver Vanin
Acta Scientiarum : Language and Culture , 2009,
Abstract: O objetivo deste texto é fazer uma breve revis o de literatura acerca do debate sobre a defini o de ‘comunidade de fala’ para a Sociolinguística. Tal conceito advém da necessidade de analisar e sistematizar as variantes utilizadas por indivíduos que compartilham informa es linguísticas similares por conviverem em uma mesma regi o.Percebe-se que, sendo a unidade de estudo da Sociolinguística, a no o de comunidade de fala acaba se tornando ampla para os propósitos dessa disciplina, levando autores a restringila a dois níveis: o de rede social e o de comunidade de prática. The aim of this text is to make a brief literature review of the various definitions of ‘speech community’ to Sociolinguistics. This concept arises from the need of analyzing the several linguistic variants used by individuals from certain place. The notion of speech community is the unit of study of Sociolinguistics, but some linguists realized that it is too broad to their purposes, which takes to restriction of this concept into two levels: the social network and the practice community concepts.
Coleoptera Larval Fauna Associated with Termite Nests (Isoptera) with Emphasis on the “Bioluminescent Termite Nests” from Central Brazil
Cleide Costa,Sergio Antonio Vanin
Psyche , 2010, DOI: 10.1155/2010/723947
Abstract: Beetle larvae that inhabit termite nests present modifications that allow them to cohabitate with the termites. Some are physogastric and bear special glands and different setae all over their bodies, whereas others are not physogastric. Both kinds of larvae may be termite predators. Some species usually live in the nest cabbage pan, feeding on organic matter, mushrooms, and excrements or eating the nest walls and sometimes causing the nest to be destroyed. Other species live in superficial galleries of the nest and feed on preys that live outside. However, all interactions between these inquilines beetles and their termite hosts are very complex and still little understood. Emphasis was done to the bioluminescent termite nests from Central Brazil and for this reason general aspects of the bioluminescence related to the elaterid fireflies were also given. The adaptations to live in nest environment and functional categories of association of all beetle larvae we have studied, including those not bioluminescent, to termite nests are discussed in this work. 1. Introduction We present here a synthesis of our papers dealing with beetle larvae found inside termite nests in Brazil, Africa (Sudan, Tanzania, Guinea, and Ivory Coast) and Australia, pointing out some aspects not dealt with yet. A numerous and diversified insect larval fauna including many beetle species is found in the interior of termite (Isoptera) nests. This fauna occurs in living colonies as well as in abandoned nests. The inside of the nest provides stable environment protected against climatic variations and enemies. In many cases the termite nest seems to constitute the main or the only place where these beetles can develop. For many years we collected and studied Coleoptera larvae, associated with termite nests, mainly species of the families Elateridae, Passalidae, Melyridae, Scarabaeidae, Tenebrionidae, and Carabidae. As most of the studied species were described by us in several papers and in a book in [1], and the species reported associated with the termite nests are of different taxa, we find it worthwhile presenting a synthesis of the gathered observations, pointing out some aspects not dealt with yet. We had had the opportunity to study larvae of Elateridae (Tetralobini) from Africa and Australia [2, 3] also collected from the inside of termite nests. The phenomenon of the bioluminescent termite nest from Central Brazil is very impressive; it is the result of the luminescent activity of Pyrearinus termitilluminans Costa, 1982 (Elateridae, Agrypninae) larvae, which are found in old

On the concepts of "pre-pupa", with special reference to the Coleoptera
Costa, Cleide;Vanin, Sergio A.;
Revista Brasileira de Zoologia , 1984, DOI: 10.1590/S0101-81751984000200004
Abstract: three main concepts of "pre-pupa" are recognized here in the holometabola: i) pre-pupa without a distinct moult but with a short quiescent period followed or not by slight modifications of the last larval instar form of body - this type corresponds to the pharate pupa; ii) pre-pupa with a distinct moult, and a quiescent resting period followed by slight form modifications (mainly in the mandibles and color pattern) with a variable period of diapause (ex. hymenoptera-symphyta); iii) pre-pupa with a distinct moult, a quiescent period not related to the diapause phenomenon, and distinct morphological modifications (coleoptera-mycteridae).

Revista Brasileira de Computa??o Aplicada , 2010, DOI: 10.5335/rbca.2012.969
Abstract: This tutorial presents an object oriented approach to data reading and metrics extraction from feature basis. Structural issues about basis are discussed first, then the Object Oriented Programming (OOP) is aplied to modeling the main elements in this context. The model implementation is then discussed using C++ as programing language. To validate the proposed model, we apply on some feature basis from the University of Carolina, Irvine Machine Learning Database. Este tutorial apresenta uma abordagem orientada a objetos à leitura e extra o de métricas de bases de características. Aspectos estruturais das bases s o apresentados inicialmente e, em seguida, os recursos da Programa o Orientada a Objetos (POO) s o aplicados na abstra o dos principais elementos presentes neste contexto. A implementa o deste modelo é discutida utilizando o C++ como linguagem de pograma o. Para validar o modelo é feita sua aplica o sobre algumas bases da (University of Carolina, Irvine Machine Learning Database).

Ten Years of the Central Italy Electromagnetic Network (CIEN) Continuous Monitoring  [PDF]
Cristiano Fidani, Daniele Marcelli
Open Journal of Earthquake Research (OJER) , 2017, DOI: 10.4236/ojer.2017.62004
Abstract: A test is being realised by means of a network of wide band electromagnetic detectors that continuously records the electric components of the electromagnetic field, ranging from a few of Hz to tens of kHz. The network has been operating in central Italy for more than ten years. The recorded signals from this network have been analysed in real time as well as their power spectrum contents. Time/frequency data have been saved for further analysis. The spectral contents have evidenced very distinct power spectrum signatures in ELF band that increase in intensity when strong seismic activity occurs near the stations, for example, at the time of Amatrice (M = 6) and Norcia (M = 6.5) earthquakes in 2016 when ten stations were operative, at the time of the Emilia (M = 6) earthquakes in 2012 when nine stations were operative, and at the time of the L’Aquila (M = 6.3) earthquakes in 2009 when only two stations were operative. Strong signals were also detected during the moderate Ancona (M = 5) earthquake in 2013 and by the recently installed Avigliano Umbro, Città di Castello and Gubbio stations in the Umbria region, during small seismic swarms (2 < M < 4) between 2013 and 2014. CIEN is presently composed of 16 stations and collect data from a multidisciplinary instrumentation.
