Victims of Racket: Entrepreneurs and Traders Dealing with Cosa Nostra, Ndrangheta, and Camorra
2015
This work proposes research on a still unexplored psychical world: thoughts, emotions, and real events experienced by racket victims of the three largest criminal organizations of the South of Italy: Mafia, Camorra, and Ndrangheta. The purpose is to understand the multifaceted psycho-anthropological and social issues criminal organizations have settled on, and particularly which psycho-relational dynamics and sociocultural codes come into play in the complex and controversial relationship between victim and criminal system, between victim and support systems. With entrepreneurs and tradesmen victims of organized crime, we have analyzed lived experiences - in particular fear - and psychologi…
Challenges in the use of Near Infrared Spectroscopy for improving wood quality: A review
2018
Aims of study: Forestry-related companies require quality monitoring methods capable to pass a large number of samples. This review paper is dealing with the utilization of near infrared (NIR) technique for wood analysis.Area of study: We have a global point of view for NIR applications and characterization of different kind of wood species is considered.Material and methods: NIR spectroscopy is a fast, non-destructive technique, applicable to any biological material, demanding little or no sample preparation. NIR spectroscopy and multivariate analysis serve well in laboratories where the conditions are controlled. The main challenges to NIR spectroscopy technique in field conditions are mo…
Découverte d'Arthropodes et de bivalves inédits dans le Permien continental (Lodévois, France)
1997
Resume Des Triopsides, Conchostraces, Insectes, Bivalves, pistes et terriers d'Arthropodes sont decouverts dans le Groupe saxonien considere longtemps comme quasi azoique. Ces fossiles sont pour la plupart inedits, au niveau de l'espece, de la famille et de l'ordre. Chez les Insectes, de nouveaux taxons comblent des lacunes temporelles considerables, allant du Jurassique au Permien. Les informations recueillies vont permettre de rediscuter certaines phylogenies et de reapprecier l'impact de la crise fini-permienne sur cette classe. La repartition des Insectes et des Conchostraces suggere de donner un âge Koungourien a Tatarien (Leonardien a Capitanien) au ≪ Saxonien ≫.
RESEARCH PAPER: Multiple Sexual Ornamentation Signals Male Quality and Predicts Female Preference in Minnows
2010
Sexual ornamentation often consists of multiple components. Different sexual signals may indicate different aspects of mate quality or reflect quality in different time scales. On the other hand, same signals can have a dual function and are used both in male–male competition and courtship. Many fish species are capable of rapidly altering their colouration (ephemeral colour changes), but this capability is usually ignored in sexual selection studies. Here, we used experimentally manipulated social environments to study the ephemeral colour changes in multicomponent sexual signals of male minnows (Phoxinus phoxinus) during male–male competition and female choice. We found that the dominant …
Intraguild interactions between egg parasitoids: window of opportunity and fitness costs for a facultative hyperparasitoid.
2013
We investigated intraguild interactions between two egg parasitoids of Nezara viridula (L.) (Heteroptera: Pentatomidae), Ooencyrtus telenomicida (Vassiliev) (Hymenoptera: Encyrtidae) and Trissolcus basalis (Wollaston) (Hymenoptera: Platygastridae), as the former has the potential to be a facultative hyperparasitoid of the latter. We assessed the suitability of N. viridula eggs for the development of O. telenomicida as a function of egg age when they were unparasitized, or had been attacked by T. basalis at different times prior to exposure to O. telenomicida females. Ooencyrtus telenomicida can exploit healthy N. viridula host eggs up to 5 days of age, just prior to the emergence of N. viri…
Cultural Competences of International Students: Its Role on Successful Sociocultural and Psychological Adaptation
2014
This chapter addresses the study of cultural competences involved in the successful adaptation of a particular group of migrants: international students. Cultural competences are skills that people display when facing cultural diversity and have been found to predict job performance and academic achievement of those who have to interact in different contexts other than their own. This chapter aims to respond three questions that students consider when studying abroad: ‘What should I do to have a successful life?’, ‘How prepared are members of the host culture to receive me?’, and, ‘Who are the most successful international students?’ The first segment introduces the role of acculturative st…

"Bad romance": Links between psychological and physical aggression and relationship functioning in adolescent couples
2015
Contains fulltext : 150442.pdf (Publisher’s version ) (Open Access) Assortative mating is an important issue in explaining antisocial, aggressive behavior. It is yet unclear, whether the similarity paradigm fully explains frequent displays of aggression in adolescents' romantic relationships. In a sample of 194 romantic partner dyads, differences between female and male partners' reports of aggression (psychological and physical) and different measures of relationship functioning (e.g., jealousy, conflicts, and the affiliative and romantic quality of the relationship) were assessed. A hierarchical cluster analysis identified five distinct subgroups of dyads based on male and female reports …
Gender, Translation, and Censorship
2019
After the “cultural turn” in the 1980s, translation was redefined as a cultural transfer rather than a linguistic transposition. Key translation concepts were revised, including equivalence, correction, and fidelity. Feminist approaches to translation emerged, for example, the recovery of texts lost in patriarchy. Following the death of Franco and the transition to democracy, Spain initiated a cultural expansion. The advent of the Franco regime after the civil war (1936-1939) resulted in years of cultural involution and the abolition of rights for women attained during the Spanish Second Republic (1931-1939). Severe censoring prevented the publication of literature—both native and foreign (…
Do highly ornamented and less parasitized males have high quality sperm? - an experimental test for parasite-induced reproductive trade-offs in Europ…
2014
Parasites take their resources from hosts and thus directly reduce available resources for hosts’ own body functions, such as growth and reproduction. Furthermore, parasite infections cause significant indirect costs to their hosts in terms of increased investments on immune defense. In this study, we investigated the impact of parasite infection on the sperm quality and expression of secondary sexual ornamentation (saturation of the red abdominal colouration and number of breeding tubercles) in the Eurasian minnow (Phoxinus phoxinus). We exposed minnows to a high and low dose of common nonspecific fish ectoparasite, the glochidia larvae of duck mussel (Anodonta anatina) and tested whether …
