Efficacy of a treatment program based on positive psychology for drug use in juvenile offenders.

One of the factors that increase the likelihood of adolescents starting to exhibit and consolidate anti-social behavior is drug use, with a consistent pattern of consumption of different substance found in young offenders (Aebi, Bessler & Steinhausen, 2021). A cognitivebehavioral group treatment program inspired by the positive psychology approach was developed and applied to drug use in minors deprived of liberty (experimental group); the results were compared to those of a group of adolescents with the same type of drug use in the same center (active control group) at two points in time: during and after incarceration. The fall in the rate of problems associated with drug use after incarceration in the experimental group was statistically significant compared to the control group, and the effect size of the experimental condition was large (ῆ2 = 0.55), much higher than the control group (ῆ2 = 0.16). The treatment program has proven to be an effective tool for reducing problems associated with drug use and is especially effective in reducing alcohol and cannabis consumption.

Do one‐step mechanisms always involve simultaneous evolution of electron density? QTAIM/IQA analysis of the Curtius rearrangement

The Curtius rearrangement reaction is studied by using quantum theory of atoms in molecules (QTAIM) analysis of the electron density and the interacting quantum atoms (IQA) formalism. Although the rearrangements take place in one stage, two phases are distinguished when the rearranged atom is H: the first one corresponds to the separation of N2, and the second one to the N‐H/C‐H bond rearrangement. The transition state (TS) for the reaction does not represent an intermediate between reagent and product for the migration but for the isolation of the N2 molecule. When the migration is undergone by a fluorine atom, no electronic phases can be distinguished and the process is really concerted. As the migration happens closer to the TS, the TS is more similar to the product. The IQA analysis reveals different electron density evolutions for H and F migrations, and the scarce relevance (in terms of energy) of the point where BCPs appear or disappear.Xunta de Galicia | Ref.

Electron density analysis on the alpha acidity of nitriles

24 substituted cyanocompounds and the corresponding anions obtained upon H + -abstraction from diverse positions were subjected to an electron density analysis with the quantum theory of atoms in molecules (QTAIM). All the electron densities were obtained at the B3LYP/6–31 +  + G(2d,2p) level on completely optimized geometries. In accordance to experimental evidence, α-H + abstraction is found as the most favored one (by at least 100 kJ mol −1 in all the tested compounds). The presence of additional resonance electron attractors reduces significantly the α-deprotonation energy, whereas this magnitude is quite insensitive to the inclusion of resonance electron donors. The electron density rearrangement accompanying the deprotonation is apparently in line with the predictions of the resonance model (RM). In fact, a significant part of the electron density gained by expelling the proton is transferred to cyano N and to other groups where significant resonance structures delocalize the negative charge. Nevertheless, some significant modifications have to be introduced on the RM picture when the QTAIM results are studied in detail.Xunta de Galicia | Ref. GRC 2019/24Universidade de Vigo/CISU

Risk prediction and assessment of intervention, re-education and reintegration of juvenile offenders: development and psychometric properties of the PREVI-A

This paper proposes and analyzes the psychometric properties of the PREVI-A scale (Predicción del Riesgo y Valoración de la Intervención en la ARRMI—-Risk Prediction and Intervention Assessment in the ARRMI). It describes the process of item development, the factorial structure of the scale, reliability, evidence of validity and diagnostic performance with regard to recidivism risk in juvenile offenders. The sample was made up of 212 juvenile offenders held at detention centers run by the Madrid Agency for Reeducation and Reintegration of Juvenile Offenders, a regional government body. Statistical analyses were used to corroborate the theoretical factorial structure of the PREVI-A, which consists of six risk/protection dimensions (64 items) based on the Risk- Needs-Responsivity Model, and to obtain empirical support for the reliability and validity of PREVI-A as a tool to assess the risk of recidivism by juvenile offenders in Spai

La “Ruta de las huellas fósiles” (Monsagro, Salamanca): un ejemplo de iniciativa geoturística aplicada al desarrollo rural

Se presenta la “Ruta de las huellas fósiles”, realizada en el casco urbano de Monsagro (Sierra de Francia, Salamanca).

Los visitantes señalan como fortalezas de la ruta su fácil y didáctico recorrido, así como la implicación ciudadana en la conservación de las icnitas

Physical and psychological aggression in dating relationships in Spanish university students

The presence of violent behaviors of a psychological and physical nature in dating relations was analyzed in a sample of Spanish university students between 18 and 27 years of age. The results indicate a high prevalence of both kinds of aggression in interpersonal relationships, revealing important typology differences between the sexes. Violent psychological behaviors (characterized by the presence of verbal aggression and coercive and jealous behaviors) and physical aggression were significantly higher in women, though the consequences of physical aggression were worse for the women’s health. The implications of the results and their possible relation with more severe violent acts in more stable, emotional relationships are discussed. Agresión física y psicológica en las relaciones de noviazgo en universitarios españoles. En el presente trabajo se analiza la presencia de comportamientos violentos de carácter psicológico y físico en las relaciones de noviazgo en una muestra de jóvenes universitarios españoles con edades comprendidas entre los 18 y los 27 años. Los resultados indican la alta prevalencia de ambos tipos de agresión en las relaciones interpersonales, encontrando diferencias importantes en cuanto a su tipología entre sexos. Así, la violencia de carácter psicológico (analizadas por la presencia de agresiones verbales y comportamientos coercitivos y celosos) y la agresión física resultaron ser significativamente superiores en el caso de las mujeres, aunque las consecuencias para la salud derivadas de la misma son más negativas para ellas. Se comentan, asimismo, las implicaciones de los resultados obtenidos y su posible relación con actos de violencia más graves en posteriores relaciones emocionales más estables

Validación de la versión modificada de la Conflicts Tactics Scale (M-CTS) en población juvenil española

La version modificada de la Conflicts Tactics Scale (M-CTS), realizada originalmente por Straus en 1979, es uno de los instrumentos más ampliamente utilizados para la detección de comportamientos violentos de carácter verbal y físico en las relaciones de noviazgo en jóvenes y adolescentes. El objetivo del presente trabajo fue analizar las propiedades psicométricas del instrumento y validar su adecuación en población española. La muestra estuvo compuesta por 5.355 jóvenes españoles pertenecientes a la Comunidad de Madrid, con edades comprendidas entre los 16 y los 26 años. A través de un Analisis Factorial Confirmatorio se identificaron cuatro factores consistentes con la teoría y las investigaciones previas: argumentación, agresión psicológica/verbal, agresión física leve y agresión física grave. Se concluye que la escala permite evaluar, con suficientes garantías psicométricas, la presencia de diferentes tipos de agresión en las relaciones de pareja en jóvenes y adolescentes

The VVV Near-IR Galaxy Catalogue beyond the Galactic disk

Knowledge about the large-scale distribution of galaxies is far from complete in the Zone of Avoidance, which is mostly due to high interstellar extinction and to source confusion at lower Galactic latitudes. Past near-infrared (NIR) surveys, such as the Two Micron All Sky Survey (2MASS), have shown the power of probing large-scale structure at these latitudes. Our aim is to map the galaxy distribution across the Southern Galactic plane using the VISTA Variables in the V\'ia L\'actea Survey (VVV), which reach 2 to 4 magnitudes deeper than 2MASS. We used SExtractor + PSFEx to identify extended objects and to measure their sizes, the light concentration index, magnitudes, and colours. Morphological and colour constraints and visual inspection were used to confirm galaxies. We present the resulting VVV NIR Galaxy Catalogue of 5563 visually confirmed galaxies, of which only 45 were previously known. This is the largest catalogue of galaxies towards the Galactic plane, with 99% of these galaxies being new discoveries. We found that the galaxy density distribution closely resembled the distribution of low interstellar extinction of the existing NIR maps. We also present a description of the 185 2MASS extended sources observed in the region, of which 16% of these objects had no previous description, which we have now classified. We conclude that interstellar extinction and stellar density are the main limitations for the detection of background galaxies in the Zone of Avoidance. The VVV NIR Galaxy Catalogue is a new data set providing information for extragalactic studies in the Galactic plane.Comment: Accepted for publication in Monthly Notices of the Royal Astronomical Society Main Journal 21 page

LanderPick, a Remote Operated Trawled Vehicle to cost-effectively deploy and recover lightweight oceanographic landers.

Landers are modular structures equipped with miscellaneous sensors and monitoring equipment which are positioned directly on the seabed to operate autonomously for a defined timeframe. A drawback of landers intended to operate for prolonged periods in the deep ocean is the high cost of recovery systems, typically depending on buoyancy modules plus expendable ballast, or requiring ROVs assistance. LanderPick concept consists of the design of a specific trawled vehicle to deploy and recover lightweight oceanographic landers not provided with recovery elements, but having a capture mesh that facilitates their hitching. The LanderPick vehicle is technically a ROTV (Remote Operated Trawled Vehicle) controlled through a standard coaxial electromechanical cable that allows real-time control from the vessel. Navigation is enabled by a low-light high-definition camera, aided by spotlights and laser pointers. Small propellers aid in the final precision approach maneuvers. A mechanical release allows the precise placement at the sea bottom of landers carried as a payload, as well as their recovery by means of a triple hook. First sea missions of the system were carried out successfully in 2021 in southern Biscay. A 4-month deployment of a lander array equipped with current-meters along an energetic canyon axis provided unprecedented detail in the progression of the internal tidal bore. Short (48-hours) deployments of a fully-instrumented lander, including lapse-time image and baits in a deep seamount summit within a marine protected area, provided insights on the biodiversity of a unique ecosystem. The LanderPick novel approach to cost-effectively and precisely deploy and recover lightweight oceanographic landers allows to conceive (i) monitoring systems based on the deployment of arrays or fleets of low-cost landers and (ii) experiments associated with deep habitats such as coral reefs in which it is necessary to locate landers with great precision
