Constructive Leisure as a Strategy For Adolescents Integration in Conflict with the Law
2014
Las actividades de ocio deben representar por sí mismas, acciones educativas con capacidad de conquistar el espacio cotidiano de los nuevos tiempos. Además, se establecen como actividades constructivas en el tránsito hacia la madurez capaces de enlazar prácticas educativas con lúdicas. Cuando se producen fracturas entre estas dos dimensiones (aprendizaje y diversión), pueden generarse espacios sobre los que las actividades orientadas al recreo constituyan en si mismas un riesgo asociado a las propias dinámicas adolescentes. La alerta surge si estos períodos acaban por esconder otras actividades desviadas que, representadas en el espacio cotidiano, transformen rutinas lúdicas en habituales p…
EVIDENCE FOR KIN-STRUCTURED GROUP FOUNDING AND LIMITED JUVENILE DISPERSAL IN THE SUB-SOCIAL SPIDER STEGODYPHUS LINEATUS (ARANEAE, ERESIDAE)
2001
Abstract In sub-social spiders, restricted dispersal of young (i.e., natal philopatry) and the potential for inbreeding could contribute to within-population subdivision, thus resulting in a population structure similar to that found in social congeners. In this context, we analyzed the origin and mode of individual distribution patterns and their contribution to within-population structure in juveniles of the sub-social spider Stegodyphus lineatus. We investigated the distribution of juveniles for four months after leaving the maternal nest using allozyme genetic markers. We found that isolated groups of juveniles consisted predominantly of siblings, whereas larger aggregations of individu…
Detection of the Spider Predator, Hololena Nedra By Naïve Juvenile Field Crickets (Gryllus Integer) Using Indirect Cues
2004
Summary In many species, prey detect predators using chemical cues, which may be based on the predator’s previous diet. Furthermore, the predator’s previous hunting strategy and diet may affect the prey’s behavioural strategies to avoid predation. Juvenile Gryllid field crickets face predation by spiders, but the responses of juvenile crickets to spiders are unknown. We studied whether naive juvenile field crickets can detect a predatory spider, Hololena nedra, using chemotactile cues (silk, secretions and excreta). We also studied the effect of the predator’s diet on the juvenile field cricket’s anti-predator behaviour. Cricket nymphs avoided the chemotactile spider cues when the spiders w…
La costruzione dell’identità femminile nel franchismo: «Y» Revista femenina española (1938-1945)
2019
Soprattutto in determinati contesti storico-politici, l’istanza del potere partecipa in modo determinante alla costruzione dell’identità individuale, di gruppo e nazionale. Affinché ciò sia possibile, il potere deve mettere in pratica una serie di misure di controllo, ricorrendo, non solo a una politica violenta e repressiva, ma anche a concreti programmi sociali e, ovviamente, all’adozione di un discorso perlocutorio, che si faccia espressione dei valori di cui si nutre ogni regime. Nell’interazione tra discorso, cognizione e società (Van Dijk, 2009: 351), la stampa svolge un ruolo cruciale, dato che si configura come uno strumento in grado di influire sulle idee e le azioni di tutti gli a…
Effects of progressive decrease of feeding frequency and re-feeding on production parameters, stomach capacity and muscle nutritional value in rainbo…
2020
Abstract Feeds and feeding constitute the major part of costs in intensive aquaculture. Any action to reduce feeding costs without negatively affecting fish production parameters and flesh quality would improve profitability of farming. Therefore, we studied the effects of feeding frequency on production parameters, stomach capacity and nutritional value of muscle in juvenile rainbow trout (Oncorhynchus mykiss) in an experiment with two stages. First, during the nine-week “starvation period” we fed rainbow trout (initial weight c. 40 g) with four different feeding protocols in an attempt to adapt the fish to a progressive decrease in the number of feeding days. During the second stage, a fo…
Effects of weekend starvation and the duration of daily feeding on production parameters of rainbow trout Oncorhynchus mykiss
2021
Abstract It would often be practical to starve the cultivated fishes over the weekends, e.g. to save in labour costs. We evaluated the possibility that domesticated juvenile rainbow trout (Oncorhynchus mykiss) could compensate for the lost growth of the 2-day weekend starvation by either hyperphagic response and/or by lower feed conversion ratio, compared to the fish fed every day in an 8-week experiment. Rainbow trout (initial weight c. 30 g, temperature 16 °C) starved during the weekends were able to increase feed intake during the weekdays clearly above the intake of the control fish after the first two weekends, also seen as an increase of the compensation coefficients over the last fou…
L'Archivio del Monastero di Santa Caterina d'Alessandria di Palermo. Inventario
2020
Il complesso architettonico di Santa Caterina si trova nel cuore del Centro storico di Palermo. Nell’archivio del monastero di Santa Caterina si conservano ancora i processi verbali nei quali il funzionario dell’Intendenza di Finanza, il priore del monastero e il patrocinatore dello stesso mettevano per iscritto, in elenco, i beni immobili e mobili della chiesa e del monastero, carte comprese25. Un proficuo e puntiglioso lavoro di riordino ha portato alla realizzazione di un inventario che, come è noto, oltre a valorizzare un patrimonio prezioso di carte e documenti, ne costituisce la chiave di accesso. Senza la possibilità, infatti, di un pieno e ordinato recupero delle informazioni conten…
Violent and/or delinquent women: a vision from the biopsychosocial perspective
2015
Violence and/or delinquency in women have been masked to some extent by society. Thus, the main goal of this work is to deeply analyse the published works on these matters, in order to understand this phenomenon from a neurobiological perspective. Firstly, the theory of the cycle of violence as a facilitating mechanism of violence in women will be analysed, with a special emphasis on neuroanatomical correlates. Subsequently, the relation between drug consumption and violence in women will be explained. Finally, the main biological correlates known as facilitating mechanisms of violence in women will be exhaustively described. The main risk factors for the facilitation of violence and/or del…
Spontaneous extrusion of male genital pearling
2021
Pearling is a practice of inserting small beads beneath the skin of the genitalia. Patients generally underwent this practice believing that this would have made their penis bigger and able to better satisfy their partners during intercourse. Pearling can cause complications. We report a case of spontaneous extrusion of genital pearling exiting in a granuloma of the inner face of the foreskin.
The complex nature of progenetic species — examples from Mesozoic ammonites
1991
Several examples of progenetic species among Mesozoic ammonites are investigated. The ammonites are Middle Jurassic kosmoceratids, Upper Jurassic oppeliids, and Upper Cretaceous scaphites. As assessed through outgroup comparison, the progenetic species in each of these examples is characterized by small size at maturity and the presence of morphological features typical of those of the juveniles of more primitive species. However, in none of these examples is the progenetic species a duplicate form of the juvenile stage of more primitive species. There are at least three kinds of features of progenetic species that differ from those of the juveniles of more primitive species: (1) symplesiom…
