The whisper with a thousand echoes: Tony Gentile’s photograph of Falcone and Borsellino

Tony Gentile’s photograph of Giovanni Falcone and Paolo Borsellino is one of the most reprinted Italian photographs of the twentieth century. Deriving a special status from its connection to the lost dead bodies of the judges, Gentile’s photograph is a cultural icon, which makes demands on viewers in the present like an uncanny revenant from 1992. This paper considers examples of ways the photograph has been visually, symbolically and materially manipulated by social agents in the years since the judges’ assassinations, to reflect on the polysemous power of the photograph. Considering visual adaptations of the photograph from anti-mafia demonstrations to monuments, and commemorative stamps; from football stadiums to political cartoons, this paper will show how Gentile’s photograph has become the quintessential visual symbol representing the struggles over the memory and meaning of the war against the mafia in contemporary Italy. La fotografia di Giovanni Falcone e Paolo Borsellino, scattata nel 1992 da Tony Gentile, è una delle fotografie italiane più famose del ventesimo secolo. La fotografia di Gentile è anche un’icona culturale che trae il proprio potere simbolico dal suo implicito legame con i corpi dei giudici uccisi. Questo articolo considera alcuni usi pubblici della fotografia sia nell’ambito della protesta che delle commemorazioni ufficiali. L’articolo si interessa in particolare alle re-invenzioni e manipolazioni grafiche e plastiche della fotografia originale, per considerare alcune ‘reazioni culturali’ al fenomeno mafioso in Italia nell’ambito della memoria collettiva

Analyse de l'activité de match chez l'arbitre de football par accéléromètre et critique des tests de sélection FIFA

Introduction : Depuis 2005, le « Test FIFA » est utilisé chez les arbitres de football, comme critère de sélection pour monter dans les échelons de l'arbitrage et chaque arbitre base son entraînement dans cet objectif. Ce test a été développé grâce aux nombreux travaux scientifiques, ayant utilisé l'analyse vidéo, afin de quantifier les activités de match des arbitres et analyser leur performance en cours de match. Objectifs : Le but de ce travail a été d'évaluer la performance de l'arbitre, lors d'un match de football, au moyen d'un accéléromètre en raison de sa facilité d'utilisation et en particulier d'évaluer si au cours du match, il existe une éventuelle diminution de la capacité de performance engendrée par la fatigue. Enfin, à la lumière des résultats, nous avons pu discuter du bien fondé du «test par intervalle proposé par la FIFA» comme moyen d'estimation de la capacité physique d'un arbitre. Méthode : Il s'agit d'une étude prospective basée sur une analyse descriptive. Les données ont été récoltées dans des stades de football suisses ≥1ère Ligue, du 01.12.2011 au 01.12.2012. Le groupe étudié était composé de 5 arbitres de football de sexe masculin, dont deux officiant en 1ère Ligue et faisant partie des talents de l'Association Cantonale Vaudoise de Football (ACVF) et trois en Super League et Challenge League. Les 5 arbitres ont été équipés d'un iPhone 3GS®, muni d'une application, capable d'enregistrer les déplacements sur le terrain (arrêt, marche et course). Le traitement des données a été effectué par un programme Matlab®, élaboré par le Laboratoire des Mesures d'Analyse du Mouvement (LMAM) de l'EPFL, tout comme l'application en question. Pour ce travail ont été considérées les phases et les fréquences d'arrêt, de marche et de course tout au long de l'évolution de la partie. Résultats : Durant les 90 minutes du match, la répartition se fait de la manière suivante : 13,74% du temps total où l'accéléromètre ne mesure aucune activité, 33,70% concernent une activité de course alors que le reste, 52,48% est de la marche. Avec l'avancement dans le match, il est constaté une augmentation des phases d'arrêt et une diminution du temps de course. Une intensité d'effort plus importante est observée lors des 15 premières minutes du match (environ  41,7% de course), alors qu'en fin de la partie, il y a une alternance de marche et de course avec des efforts de plus en plus brefs. La détermination de la médiane de durée des différents efforts a montré qu'un épisode de marche ou de course étaient de 5-6 secondes. De plus, les épisodes de marche ou de course étaient rarement >20 secondes. Discussion : Les résultats montrent que l'accéléromètre est un système de mesure facile d'utilisation, permettant un gain de temps dans l'analyse des données pour évaluer la performance sportive. Les principaux résultats de cette étude, ont mis en évidence une diminution de l'intensité des activités physiques de l'arbitre avec l'avancement du match, résultant soit de sa propre fatigue, soit de celle des joueurs dictant le rythme du jeu. Cette diminution se traduit par des déplacements de plus en plus brefs au fil du temps. La mesure de médiane du temps de course et de marche (5-6 sec) correspond à une activité aérobie pour la marche et anaérobie alactique pour la course. Par conséquent, le « test par intervalle » de la FIFA actuel ne nous semble pas adéquat en raison de sa filière énergétique de type anaérobique lactique. Conclusion : Cette étude pilote apporte un nouveau type d'instrumentation efficace et simple, jamais employé auparavant dans l'analyse des activités de match des arbitres de football. Il permet d'explorer des mouvements avec précision au fil du match et apporte un nouvel aspect sur la quantification de performance des arbitres non exploré jusqu'ici. Après analyse de l'ensemble des paramètres, il semble que le test FIFA ne soit pas adapté à la performance exigée par l'arbitrage

Phylogenetic signal in amphibian sensitivity to copper sulfate relative to experimental temperature

The release of large quantities of chemicals into the environment represents a major source of environmental disturbance. In recent years, the focus of ecotoxicology has shifted from describing the effects of chemical contaminants on individual species to developing more integrated approaches for predicting and evaluating long term effects of chemicals across species and ecosystems. Traditional ecotoxicology is typically based on data of sensitivity of a few surrogate species to a contaminant and often considers little variability in chemical sensitivity within and among taxonomic groups. This approach assumes that evolutionary history and phylogenetic relatedness among species have little or no impact on species’ sensitivity to chemical compounds. Few studies have tested this assumption. Using phylogenetic comparative methods and published data for amphibians, we show that sensitivity to copper sulfate, a commonly used pesticide, exhibits a strong phylogenetic signal when controlling for experimental temperature. Our results indicate that evolutionary history needs to be accounted for to make accurate predictions of amphibian sensitivity to this contaminant under different temperature scenarios. Since physiological and metabolic traits showing high phylogenetic signal likely underlie variation in species sensitivity to chemical stressors, future studies should evaluate and predict species vulnerability to pollutants using evolutionarily informed approaches

Ideas for a phenomenological interpretation and elaboration of personal construct theory. Part 1. Kelly between constructivism and phenomenology

Kelly’s personal construct theory, put forward in 1955, is considered the first constructivist theory of personality and the first expression of those contemporary psychotherapeutic perspectives grounded on a constructivist view of knowledge. Notwithstanding the similarities between psychological constructivism and the phenomenological-hermeneutic tradition, Kelly always rejected the parallel of his theory to phenomenology, regarding the latter as unacceptable since idealistic, solipsistic, and particularistic. In this first article of a work subdivided into three parts, the Authors explain such criticism by Kelly with his knowledge of phenomenology deriving from secondary sources, and stress the wide possibilities of a phenomenological interpretation and elaboration of his theory

Isolating and Quantifying the Role of Developmental Noise in Generating Phenotypic Variation

Genotypic variation, environmental variation, and their interaction may produce variation in the developmental process and cause phenotypic differences among individuals. Developmental noise, which arises during development from stochasticity in cellular and molecular processes when genotype and environment are fixed, also contributes to phenotypic variation. While evolutionary biology has long focused on teasing apart the relative contribution of genes and environment to phenotypic variation, our understanding of the role of developmental noise has lagged due to technical difficulties in directly measuring the contribution of developmental noise. The influence of developmental noise is likely underestimated in studies of phenotypic variation due to intrinsic mechanisms within organisms that stabilize phenotypes and decrease variation. Since we are just beginning to appreciate the extent to which phenotypic variation due to stochasticity is potentially adaptive, the contribution of developmental noise to phenotypic variation must be separated and measured to fully understand its role in evolution. Here, we show that variation in the component of the developmental process corresponding to environmental and genetic factors (here treated together as a unit called the LALI-type) versus the contribution of developmental noise, can be distinguished for leopard gecko (Eublepharis macularius) head color patterns using mathematical simulations that model the role of random variation (corresponding to developmental noise) in patterning. Specifically, we modified the parameters of simulations corresponding to variation in the LALI-type to generate the full range of phenotypic variation in color pattern seen on the heads of eight leopard geckos. We observed that over the range of these parameters, variation in color pattern due to LALI-type variation exceeds that due to developmental noise in the studied gecko cohort. However, the effect of developmental noise on patterning is also substantial. Our approach addresses one of the major goals of evolutionary biology: to quantify the role of stochasticity in shaping phenotypic variation

Dessert freddi: criteri per la loro classificazione [Cold dessert: criteria for their classification]

The expression “cold desserts” names a heterogeneous group of sweet products, which includes gelati, ice cream, pudding, mousse and more. The present work develop an inventory of all the sweet products falling under the definition of “cold desserts”. To reach this aim, several databases (Mintel GNPD), pastry’s books, industrial, as well as artisanal, products are going to be consulted. Moreover, the research has the objective to advance a rational organization of the sweet products comprised by the “cold dessert”’s definition. Thanks to such a logical organization, it will be possible to develop homogenous groupings of products, according to their characteristics. The variables with the greatest discriminating and grouping power employed in this research are: the product’s temperature of consumption, its structure, and the modalities through which it incorporates the air. The main difference between industrial and artisanal gelato is indeed in the modalities through which the air is incorporated in the products and in their consequently different rheological properties

Field Induced Staggered Magnetization and Magnetic Ordering in Cu2(C5H12N2)2Cl4Cu_2 (C_5 H_{12} N_2)_2 Cl_4

We present a $^2$D NMR investigation of the gapped spin-1/2 compound $Cu_2 (C_5 H_{12} N_2)_2 Cl_4$. Our measurements reveal the presence of a magnetic field induced transverse staggered magnetization (TSM) which persists well below and above the field-induced 3D long-range magnetically ordered (FIMO) phase. The symmetry of this TSM is different from that of the TSM induced by the order parameter of the FIMO phase. Its origin, field dependence and symmetry can be explained by an intra-dimer Dzyaloshinskii-Moriya interaction, as shown by DMRG calculations on a spin-1/2 ladder. This leads us to predict that the transition into the FIMO phase is not in the BEC universality class.Comment: 4 page
