Factores dinámicos en el comportamiento de delincuentes juveniles con perfil de ajuste social. Un estudio de reincidencia
2017
RESUMEN Este estudio tiene por objeto evaluar el riesgo de reincidencia, analizando el impacto de los factores dinámicos en adolescentes en conflicto con la ley (ACL). Para ello, se evalúa una muestra de 157 ACL con perfil de ajuste social mediante el instrumento para la evaluación del riesgo de violencia de adolescentes Structured Assesment of Violence Risk in Youth (SAVRY), además de otras técnicas de análisis cualitativo que triangulan el proceso empírico. Por un lado, destaca que la amplia estructura relacional y la vinculación intermitente con redes formales e informales de aprendizaje y empleo de que disponen los ACL con perfil de ajuste estiman un buen nivel de ajuste futuro y una ba…
Pre-invasion history and demography shape the genetic variation in the insecticide resistance-related acetylcholinesterase 2 gene in the invasive Col…
2012
Abstract Background Invasive pest species offers a unique opportunity to study the effects of genetic architecture, demography and selection on patterns of genetic variability. Invasive Colorado potato beetle (Leptinotarsa decemlineata) populations have experienced a rapid range expansion and intense selection by insecticides. By comparing native and invasive beetle populations, we studied the origins of organophosphate (OP) resistance-associated mutations in the acetylcholinesterase 2 (AChE2) gene, and the role of selection and demography on its genetic variability. Results Analysis of three Mexican, two US and five European populations yielded a total of 49 haplotypes. Contrary to the exp…
Quelques problèmes d'analyse de la délinquance juvénile à la fin du XIXe siècle. L'exemple parisien
2012
La question de la déviance des jeunes a donné naissance à nombre de travaux historiques. Dans le cadre des recherches initiées, depuis deux décennies, par Michelle Perrot et Jacques-Guy Petit sur le « système pénitentiaire », l’étude des colonies de jeunes détenus constitue un des champs privilégiés de l’exploration des diverses formes de l’emprisonnement. Force est de constater que les recherches sont moins nombreuses sur les décisions judiciaires qui conduisent ces jeunes en maison de corre...
La fuga impossibile. Sulla narrativa di Maria Messina
2017
I tre saggi di cui consta il volume, affrontando nodi critici centrali, ma anche questioni più particolari, tendono comunque a fornire un'interpretazione complessiva della figura e dell'opera della narratrice. Il primo saggio ("Ideologia e struttura nell'opera della Messina") si avvale di un approccio critico che dall'analisi dei meccanismi costruttivi dei testi risale alla struttura conoscitiva. Ne risulta il quadro di una scrittura ambivalente (tra liberazione di tensioni e di rifiuti e resa o, in certi casi, fedeltà al sistema sociale vigente). In connessione a queste tematiche è affrontato anche il rapporto della scrittrice con il realismo. Le contraddizioni e le ambiguità dell'autrice …

Maternal effects in vulnerability to eye-parasites and correlations between behavior and parasitism in juvenile Arctic charr
2017
Hatchery-reared fish show high mortalities after release to the wild environment. Explanations for this include potentially predetermined genetics, behavioral, and physiological acclimation to fish farm environments, and increased vulnerability to predation and parasitism in the wild. We studied vulnerability to Diplostomum spp. parasites (load of eye flukes in the lenses), immune defense (relative spleen size) and antipredator behaviors (approaches toward predator odor, freezing, and swimming activity) in hatchery-reared juvenile Arctic charr (Salvelinus alpinus) using a nested mating design. Fish were exposed to eye-fluke larvae via the incoming water at the hatchery. Fish size was positi…
Specific Recognition of the 5′-Untranslated Region of West Nile Virus Genome by Human Innate Immune System
2022
In the last few years, the sudden outbreak of COVID-19 caused by SARS-CoV-2 proved the crucial importance of understanding how emerging viruses work and proliferate, in order to avoid the repetition of such a dramatic sanitary situation with unprecedented social and economic costs. West Nile Virus is a mosquito-borne pathogen that can spread to humans and induce severe neurological problems. This RNA virus caused recent remarkable outbreaks, notably in Europe, highlighting the need to investigate the molecular mechanisms of its infection process in order to design and propose efficient antivirals. Here, we resort to all-atom Molecular Dynamics simulations to characterize the structure of th…
De Novo Assembly and Functional Annotation of the Olive (Olea europaea) Transcriptome
2013
Olive breeding programmes are focused on selecting for traits as short juvenile period, plant architecture suited for mechanical harvest, or oil characteristics, including fatty acid composition, phenolic, and volatile compounds to suit new markets. Understanding the molecular basis of these characteristics and improving the efficiency of such breeding programmes require the development of genomic information and tools. However, despite its economic relevance, genomic information on olive or closely related species is still scarce. We have applied Sanger and 454 pyrosequencing technologies to generate close to 2 million reads from 12 cDNA libraries obtained from the Picual, Arbequina, and L…
Tra Gaspar Serrano e Giovan Battista Contini: la riforma seicentesca del campanile della cattedrale di Saragozza
2010
La collocazione della campana Valera, rifusa nel 1679, comportò la necessità di costruire un nuovo e più solido campanile per la cattedrale di Saragozza. Dal 1680, infatti, si avvicendarono nella città aragonese diversi artefici che presentarono al Capitolo svariati progetti da sottoporre al giudizio di Francisco de Herrera el Mozo, architetto di Carlo II. La prima pietra della torre fu posta il 4 luglio 1681 su direzione dei maestri locali Jaime Borbón, Francisco López e Gaspar Serrano. L’atteggiamento ostile mostrato da Francisco de Herrera nella valutazione di nuovi progetti costrinsero i canonici a rivolgersi ai più importanti architetti attivi in quel momento a Roma, fulcro del mondo c…
A study of the pattern of digestive enzimes in Diplodus puntazzo (Cetti, 1777) (Osteychthyes, Sparidae): evidence for the definition of nutritional p…
2005
The digestive enzymes (proteases, carbohydrases and lipases) present along the alimentary tract of juveniles and adults of Diplodus puntazzo were studied. The data obtained showed a different distribution of the enzymatic activities in the different parts of the alimentary tract. Levels of enzymatic activity in the adults were higher than those measured in juveniles, suggesting that adults have a greater ability to digest larger pieces of food. The enzymatic pattern of D. puntazzo justifies its omnivorous habit and suggests an high potential for digesting vegetable polysaccharides. The results of this study suggest the need to adapt the diet to the digestive potential of this new farming sp…
