    The integrity of online games has important economic consequences for both the gaming industry and players of all levels, from professionals to amateurs. Where there is a high likelihood of cheating, there is a loss of trust and players will be reluctant to participate — particularly if this is likely to cost them money. Chess is a game that has been established online for around 25 years and is played over the Internet commercially. In that environment, where players are not physically present “over the board” (OTB), chess is one of the most easily exploitable games by those who wish to cheat, because of the widespread availability of very strong chess-playing programs. Allegations of cheating even in OTB games have increased significantly in recent years, and even led to recent changes in the laws of the game that potentially impinge upon players’ privacy. In this work, we examine some of the difficulties inherent in identifying the covert use of chess-playing programs purely from an analysis of the moves of a game. Our approach is to deeply examine a large collection of games where there is confidence that cheating has not taken place, and analyse those that could be easily misclassified. We conclude that there is a serious risk of finding numerous “false positives” and that, in general, it is unsafe to use just the moves of a single game as prima facie evidence of cheating. We also demonstrate that it is impossible to compute definitive values of the figures currently employed to measure similarity to a chess-engine for a particular game, as values inevitably vary at different depths and, even under identical conditions, when multi-threading evaluation is used

    In 2007 in every European Union region, involved in the planning of Rural Development Plan (RDP), an independent evaluator should asses the impact of the plan in term of value added and productivity. Each region has adopted different methodologies but few of them have followed the indications of Common and Monitoring Evaluation Framework (CMEF) to evaluate the net value deriving by direct and indirect effect. IRPET, the Independent evaluator of Tuscany, utilising REMI-IRPET model has assed the impact of RDP on the main economic variables until 2020. Among 30 different measures it has been chosen only 5 of them that cover more than 54% of total amount of public and private investments. The economic impacts are also evaluated at provincial level.evaluation, regional model, rural development, Community/Rural/Urban Development,

    Maquiavel e a corrupção: doença e remédio

    No full text
    A presente tese procurou refletir o problema da corrupção presente no pensamento político republicano do secretário da República Florentina. Para o autor, a experiência histórica da República de Roma na Antiguidade era a fonte de imitação e inspiração adequada para cumprir a meta de realização do maior sonho diurno de Maquiavel: a unificação política da Itália. Procuramos, nessa tese, reunir as várias falas de Maquiavel sobre a corrupção, focando a relação desse problema com a sua feição natural e inevitável, com o aumento da riqueza privada, com as ordenações e a construção das leis. Ao mesmo tempo, estudamos a relação entre corrupção e religião, corrupção e educação, e a relação desse problema com os contatos externos estabelecidos por uma determinada república. A partir desse percurso, podemos afirmar a tese de que Maquiavel, quando pensa a corrupção, refere-se a esta como sendo uma doença, e busca, ao mesmo tempo, os remédios para sanar esse mal. Os remédios são de naturezas diversas, como aponta o autor, entretanto exige uma ampla responsabilidade por parte dos cidadãos, para que estes, no desenrolar dos conflitos naturais e inevitáveis da república, possam forçar a aplicação desses remédios, preparando os conflitos políticos para o aperfeiçoamento da liberdade republicana.The present dissertation sought to reflect upon the corruption problem present in the republican thought of Florentine Republic secretary. For the author, the historical experience of Rome Republic in Antiquity was the adequate source of imitation as well as inspiration to reach Machiavelli s greatest daytime dream: the Italian political unification. In this work, we tried to reunite Machiavelli s many speeches on corruption, relating this problem to his natural and unavoidable trait, with the rising of private life, to law and order construction. At the same time, we investigated the relation between corruption and religion, as well as corruption and education and how such problems were related to external contacts set out by one specific republic. Based on this, it is possible to affirm that when Machiavelli focuses on corruption, he believes it as sickness, and then seeks the remedies to heal it. As the author points out, although such remedies are of diverse nature, they demand a high responsibility from citizens, so that, as republic natural and unavoidable conflicts develop, they are able to force the use of the remedies, preparing the political conflicts to the republic freedom enhancement

    Sull'inquadramento sistematico delle obbligazioni nella Parafrasi di Teofilo (e nelle Istituzioni giustinianee)

    The contribution deals with the origin of the particular place assigned in the Paraphrase of Theophilos to Obligations in relation to the Institutional System ‘personae-res-actiones’. The Author suggests that the displacement of Obligations from the field of the res to the field of the actiones and the representation of Obligations as “mothers of actions”, instead of deriving from an existing idea of Theophilos or from a general byzantine view, is influenced by some passages of the Justinian’s Institutions

    Predicting strategic change of public research institutions under unstable negative growth

    The purpose of this paper is to forecast and analyse, by a demographic perspective, the organizational behaviour of public research labs. The research focuses on the biggest Italian public research body. Demographic models of growth, based on different human resource policies, show the uncertain and retrogressive evolutionary change of Italian public research bodies that would halve their research personnel over the forecast horizon. These results provide vital information to the public management about the weaknesses and environmental threats in order to support decisions for improving the strategic change and survival of public research institutions over time.Organizational Studies, Forecasting, Public Research Institutions, Internal Demography

    Tese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em LiteraturaEsta tese busca problematizar um estudo comparado entre a Divina commedia e o Grande sertão: veredas a partir da noção de "Homo viator". Para tanto, nossa análise se concentrou sobre a percepção do aprimoramento do viajante que é também o protagonista nas duas obras Este viajante ficcional é concebido segundo um feixe de relações que Dante-autor e Guimarães Rosa realizam ao compor suas obras, de maneira que nos primeiro e segundo capítulos nos detivemos em alguns destes elementos, a saber: a presença da noção de êxodo bíblico bem como do viajante náutico greco-latino na caracterização deste viajante, o recurso ao narrador-protagonista e a composição das obras como literatura de viagem. Para analisar estes elementos nos utilizamos dos postulados da literatura comparada, da teoria dos arquétipos e da metafísica platônica. Por fim, no terceiro capítulo, realizamos um confronto entre dois episódios das referidas obras: a viagem de Ulisses presente no canto XXVI do Inferno e a viagem ao Liso do Sussuarão presente no Grande sertão: veredas. Este estudo tem por finalidade apresentar o "Homo viator" como metáfora da incansável busca humana da verdade.This dissertation performs a comparative study between the Divina Commedia and Grande Sertão: Veredas, having as a starting-point the notion of "Homo viator". Our analysis focuses on the path towards improvement undertaken by the "traveler", who is also the protagonist in both works. This fictional traveler is conceived of as a nexus of relationships that Dante-the-author and Guimarães Rosa construct in the making of each of their works, and it is to some of these relationships that we will pay attention in the first and second chapters, namely: the notion of the biblical exodus; the figure of the Roman-Greek nautical traveler in the characterization of the "homo viator"; the narratorprotagonist as a narrative device; and the caracterization of the works as travel literature. In order to perform an analysis of such elements, we draw our theoretical premises from the field of comparative literature, the theory of archetypes, and Platonic metaphysics. Lastly, in the third chapter, we compare and contrast two episodes from the referred works: the journey undertook by Ulysses in Canto XXVI of the Inferno, and the crossing of the "Liso do Sussuarão" in Grande Sertão: Veredas. The current work aims to present the "Homo viator"as a metaphor for the indefatigable human quest for truth

    The Harvesting Memories project aims to investigate the historical landscape dynamics in an inner area of the Sicani Mountains district in Western Sicily (Contrada Castro, Corleone-Palermo). The interdisciplinary approach of the project allowed us to combine and integrate methods from different disciplines such as historical ecology, landscape archaeology, archaeobotany and GIS-based spatial analysis. In this paper some results have been summarized. The comparison between land mosaic change during the last 60 years, the relationship between site catchment area and land suitability and the correlation between archaeobotanical and phytosociological data. This approach underlined the relevance of the historical ecology for understanding landscape trajectories and planning strategy of suitable development of rural areas. © 2022 by the author(s

    Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura, Florianópolis, 2013Esta pesquisa de mestrado acadêmico busca evidenciar as relações dialógicas do romance brasileiro A Divina Paródia, sobretudo para com a obra A Divina Comédia, ambas tratadas neste estudo como realização literária do inferno alegórico cristão. Para isso, pelo viés dos estudos comparados entre Teologia e Literatura, revisitam-se conceitos teóricos, especialmente escatológicos e paródicos, buscando-se perceber o sentido do gênero paródico com laços religiosos no contexto da contemporaneidade.This Master's degree academic research aims at pointing the dialogic relations in the Brazilian novel A Divina Paródia (The Divine Parody), especially between it and The Divine Comedy, both works portrayed in this study as literary depiction of the Christian allegoric hell. To do so, considering the compared studies between Theology and Literature, theoretical concepts are revisited, mostly eschatological and parodic ones, in an attempt of understanding the meaning of the parodic genre with religious bonds contemporarily

    16 pages, 5 figures, supplementary materials https://www.mdpi.com/article/10.3390/ijms25179604/s1.-- Data Availability Statement: All related data are included in either the manuscript or Supplementary Information. Other data are available from the corresponding author upon requestSpermatozoon volume regulation is an essential determinant of male fertility competence in mammals and oviparous fishes. In mammals, aquaporin water channels (AQP3, -7 and -8) have been suggested to play a role in spermatozoon cell volume regulatory responses in the hypotonic female oviduct. In contrast, the ejaculated spermatozoa of marine teleosts, such as the gilthead seabream (Sparus aurata), experience a high hypertonic shock in seawater, initially resulting in an Aqp1aa-mediated water efflux, cell shrinkage and the activation of motility. Further regulatory recovery of cell volume in post-activated spermatozoa is mediated by Aqp4a in cooperation with the Trpv4 Ca2+ channel and other ion channels and transporters. Using a paralog-specific antibody, here, we show that seabream spermatozoa also express the aquaglyceroporin AQP3 ortholog Aqp3a, which is highly accumulated in the mid posterior region of the spermatozoon flagella, in a similar pattern to that described in mouse and human sperm. To investigate the role of Aqp3a in seabream sperm motility, we used a recently developed AQP3 antagonist (DFP00173), as well as the seabream Aqp3a-specific antibody (α-SaAqp3a), both of which specifically inhibit Aqp3a-mediated water conductance when the channel was heterologously expressed in Xenopus laevis oocytes. Inhibition with either DFP00173 or α-SaAqp3a did not affect sperm motility activation but did impair the spermatozoon motion kinetics at 30 s post activation in a dose-dependent manner. Interestingly, in close resemblance to the phenotypes of AQP3-deficient murine sperm, electron microscopy image analysis revealed that both Aqp3a inhibitors induce abnormal sperm tail morphologies, including swelling and angulation of the tail, with complete coiling of the flagella in some cases. These findings suggest a conserved role of Aqp3a as an osmosensor that regulates cell volume in fish spermatozoa under a high hypertonic stress, thereby controlling the efflux of water and/or solutes in the post-activated spermatozoonThis work was supported by the Spanish Ministry of Science and Innovation (MCIN/AEI/10.13039/501100011033) and FEDER “A way of making Europe”, European Union, Grants no.
