Knowledge, the Great Challenge to Deal with Terrorism

Terrorism, radicalisation and violent extremism are great challenges in these times of uncertainty. This paper analyses the need to improve the knowledge to provide a solid foundation for the design of effective security Counter-Terrorism strategies. Broad definitions of stakeholders are considered (including universities, think-tanks, the intelligence community, media, communities, and minorities and citizens), together with the integration of methods and techniques of analysis drawn from the social sciences and intelligence techniques. It proposes new approaches to generate knowledge through the integration of critical perspectives allowing an improved decision-making process that must be followed by continuous evaluations

The audiovisual structure of onomatopoeias: An intrusion of real-world physics in lexical creation

Sound-symbolic word classes are found in different cultures and languages worldwide. These words are continuously produced to code complex information about events. Here we explore the capacity of creative language to transport complex multisensory information in a controlled experiment, where our participants improvised onomatopoeias from noisy moving objects in audio, visual and audiovisual formats. We found that consonants communicate movement types (slide, hit or ring) mainly through the manner of articulation in the vocal tract. Vowels communicate shapes in visual stimuli (spiky or rounded) and sound frequencies in auditory stimuli through the configuration of the lips and tongue. A machine learning model was trained to classify movement types and used to validate generalizations of our results across formats. We implemented the classifier with a list of cross-linguistic onomatopoeias simple actions were correctly classified, while different aspects were selected to build onomatopoeias of complex actions. These results show how the different aspects of complex sensory information are coded and how they interact in the creation of novel onomatopoeias.Fil: Taitz, Alan.

Presente y futuro del terrorismo de extrema derecha en Europa

Is there a risk of increased terrorism of the extreme right in Europe? This document analyses the current and future situation. Highlighting the fuzzy concepts of «terrorism» and «extreme right», the authors develop a critical analysis of the treatment of the phenomenon, noting existing factors for possible aggravation in the future. Finally, they offer several recommendations that would allow to address more effectively the latent threatY a-t-il un risque de propagation du terrorisme d’extrême droite en Europe? Ce document analyse la situation actuelle ainsi que la future. Partant des concepts diffus de «terrorisme» et d’«extrême droite», les auteurs mènent une analyse critique du traitement du phénomène, en soulignant les facteurs susceptibles d’aggraver l’état de choses actuel. Enfin, ils offrent plusieurs recommendations afin de répondre à cette menace latent de manière approprié

Serological Relationships in the <i>Leptodactylus pachypus</i> Species Group (Amphibia, Salientia)

Precipitin tests indicate that Leptodactylus ocellatus and L. chaquensis are more closely related than either is to L. pentadactylus. However, the serological differences between L. ocellatus and L. chaquensis support a separate specific ranking for these forms. Populational variations of the specific antigens occur in all 3 species.Material digitalizado en SEDICI gracias a la colaboración del Dr. Jorge Williams (FCNM-UNLP).Facultad de Ciencias Naturales y Muse

Electrophoretic Patterns and Systematic Relations in South American Toads'

Since 1959 our interest has been addressed to the study and control of the specificity and characteristics of the seroproteinic patterns of neotropical batrachians belonging to the local bufonid and leptodactylid stocks. We have observed a remarkable and specific constancy in their electrophoretic patterns, under standard conditions of comparison.Material digitalizado en SEDICI gracias a la colaboración del Dr. Jorge Williams (FCNM-UNLP).Facultad de Ciencias Naturales y Muse

Bicarbonate is required for migration of sperm epididymal protein DE/CRISP-1 to the equatorial segment and expression of rat sperm fusion ability

Numerous studies have demonstrated that sperm capacitation is a bicarbonate-dependent process. In the rat, capacitation has not been studied as much as in other species, mainly because of the difficulties in carrying out functional assays with this animal model. In the present study, we have examined the influence of bicarbonate in the overall rat sperm capacitation process by analyzing involvement of the anion in 1) protein tyrosine phosphorylation, 2) migration of epididymal protein DE (also known as CRISP-1) from the dorsal region to the equatorial segment of the sperm head that occurs during capacitation, and 3) ability of sperm to fuse with the egg. Incubation of sperm under capacitating conditions produced a time-dependent increase in protein tyrosine phosphorylation. This phosphorylation did not occur in the absence of HCO3- and rapidly increased by either exposure of sperm to HCO3- or replacement of the anion by a cAMP analog (dibutyryl-cAMP) and a phosphodiesterase inhibitor (pentoxifylline). The absence of HCO3- also produced a significant decrease in the percentage of cells showing migration of DE to the equatorial segment. This parameter was completely restored by addition of the anion, but dibutyryl-cAMP and pentoxifylline were not sufficient to overcome the decrease in DE migration. Sperm capacitated in the absence of HCO3- were unable to penetrate zona-free eggs independent of the presence of the anion during gamete coincubation. Exposure of these sperm to bicarbonate, or replacement of the anion by dibutyryl-cAMP and pentoxifylline, only partially restored the sperm fusion ability. Altogether, these results indicate that, in addition to its influence on protein tyrosine phosphorylation, bicarbonate is required to support other rat sperm capacitation- associated events, such as migration of DE to the equatorial segment, and expression of the ability of sperm to fuse with the egg.Fil: Da Ros, Vanina Gabriela.

Parenting Practices, Life Satisfaction, and the Role of Self-Esteem in Adolescents

Introduction: Studies have shown significant associations between parenting practices, life satisfaction, and self-esteem, and the role of parenting practices in adolescent adjustment, emphasizing its influence on wellbeing. Objectives: To analyze the relationships between parenting practices, self-esteem, and life satisfaction, and test the mediating effect of self-esteem on the relationship between the different parenting practices and life satisfaction of adolescents. Method: The sample came to a total of 742 adolescents, with an average age of 15.63 (SD = 1.24; range 13–19). The Parenting Style Scale, the Rosenberg Self-Esteem Scale, and the Satisfaction with Life Scale were used. Results: Perception by adolescents of high levels of affect and communication, self-disclosure, and a sense of humor related to their parents, as well as low levels of psychological control, explained the life satisfaction of the adolescents. Self-esteem exerted a partial mediating effect on the relationship between parenting practices and satisfaction with the life of the adolescent. Finally, self-esteem also appeared to be a moderator variable, specifically in the effect of self-disclosure on the life satisfaction of the adolescent. Conclusions: The results reinforce the role of personal variables, especially self-esteem, in parent-child interaction and in the improved subjective wellbeing of the adolescent

Grief Experiences in Family Caregivers of Children with Autism Spectrum Disorder (ASD)

The main objective of this study was to analyse the experience of grief and feelings of loss in family caregivers of children diagnosed with autism spectrum disorder (ASD), as well as the perceived overload from taking on the primary caregiver role. Twenty family caregivers of children with ASD participated. The family members were assessed using an ad-hoc semi-structured interview that addressed the families' reactions to the diagnosis, implications for daily functioning, and concerns for the immediate and long-term future of their relatives with ASD. The results indicate that family caregivers of children with ASD endure intense and continuous sorrow and grief due to the impact that having and caring for a child with these characteristics has on all aspects of their lives. These data highlight the importance of creating support and intervention programmes and services focused on the feelings and manifestations of ambiguous grief that occur in these family members, in order to improve their well-being and quality of life and reduce caregiver role overload
