RESUMEN

This study investigates the personality traits and motivations of collaborationists with Russian invaders in Ukraine. A focus group of individuals who knew collaborationists personally identified 14 collaborationism motives (CMs), which were used to interview 104 probation clients convicted of collaborationism. The study utilized the five-factor model developed by Costa and McCrae to evaluate individual characteristics. Categorical principal component analysis (CATPCA) reduced the 14 CMs to three dimensions: pragmatism, adaptation, and fear. The study found that individual factors promoting collaborationism included pragmatism, ideological adaptation to changing realities, and fear stemming from threats to the life and health of an individual and/or their relatives. The study provides insights into the psychology of collaborationism, which can be useful in designing resocialization programs during the probation period of collaborationists.

RESUMEN

Objective: This study aimed to analyze the influence and measurement of the relationship and interaction between the elderly lifestyles after the appearance of the SARS-CoV-2 variant and the factors analyzed comprised life satisfaction levels, social relationships, and daily-life activities. Methods: The study population was ≥ 65 in Castile-La Mancha (N = 390,221). The research design was quantitative and arose from primary data collected via an ad hoc survey carried out through the Computer Assisted Telephone Interview system by randomly stratified sampling. The sample size was made up of 1,065 cases, and the participants were selected through a random sampling stratified by gender quotas (55.40% women; 44.60% men), age ( x ¯   =   76 . 56 ), province, and habitat size. Results: The results obtained revealed two main lifestyles, from which a notable behavioral change in personal relationships led to infer toward alternative lifestyles. Conclusion: Notwithstanding the variation in lifestyles of the elderly after the pandemic, certain relationships remained unaltered. Thus, from the analyzed variables, relatives and friends relationships were scarcely influenced by the supervened incident.

RESUMEN

Chimpanzees used as pets and in the entertainment industry endure detrimental living conditions from early infancy onwards. The preferred option for ending their existence as pet or circus chimpanzees is their rescue and transfer to a primate sanctuary that will provide them with optimal living and social conditions, so that they can thrive. In this case study, we had the rare opportunity to compare the activity budgets of three chimpanzees from their time as pets in 2004 to their time living at the MONA sanctuary in 2020, after almost a decade in the centre. We found their behaviour patterns changed in accordance with the sanctuaries' rehabilitation objectives. Resting periods increased considerably while vigilance simultaneously declined sharply. Moreover, the chimpanzees' social competence increased as allogrooming became the predominant social behaviour, and agonistic interactions diminished even though they were living within a larger social group at the sanctuary. All three chimpanzees expanded their allogrooming and proximity networks at the sanctuary, which included new group members, but they maintained the closest relationships to those conspecifics who they were rescued with. In conclusion, these findings suggest that the sanctuary environment and social group setting made it possible for these three chimpanzees to improve their social competence and increase their well-being over time.

RESUMEN

BACKGROUND: Social isolation (SI) leads to various mental health disorders. Despite abundant studies on behavioral and neurobiological changes induced by post-weaning SI, the characterization of its imaging correlates, such as resting-state functional connectivity (RSFC), is critically lacking. In addition, the effects of resocialization after isolation remain unclear. Therefore, this study aimed to explore the effects of 1) SI on cortical functional connectivity and 2) subsequent resocialization on behavior and functional connectivity. METHODS: Behavioral tests were conducted to validate the post-weaning SI mouse model, which is isolated during the juvenile period. Wide-field optical mapping was performed to observe both neuronal and hemodynamic signals in the cortex under anesthesia. Using seed-based and graph theoretical analyses, RSFC was analyzed. SI mice were then resocialized and the array of behavior and imaging tests was conducted. RESULTS: Behaviorally, SI mice showed elevated anxiety, social preference, and aggression. RSFC analyses using the seed-based approach revealed decreased cortical functional connectivity in SI mice, especially in the frontal region. Graph network analyses demonstrated significant reduction in network segregation measures. After resocialization, mice exhibited recovered anxiogenic and aggressive behavior, but RSFC data did not show significant changes. CONCLUSIONS: We observed an overall decrease in functional connectivity in SI mice. Moreover, resocialization restored the disruptions in behavioral patterns but functional connectivity was not recovered. To our knowledge, this is the first study to report that, despite the recovering tendencies of behavior in resocialized mice, similar changes in RSFC were not observed. This suggests that disruptions in functional connectivity caused by social isolation remain as long-term sequelae.

RESUMEN

Chronic Social Isolation (CSI) is a model of prolonged stress employed in a variety of studies to induce depression and anxious behavior in rats. The present study aims to evaluate the effect of CSI on male Wistar rats in terms of "anhedonic-type" behavior in the Sucrose Preference Test (SPT) and anxiogenic profile in the elevated-plus-maze (EPM) test, as well as evaluating the effect of resocialization upon sucrose consumption. A total of 24 adolescent male Wistar rats were evaluated. The animals were housed either together (communally) or socially isolated for 21 days, and then exposed for four consecutive days to the SPT test [water vs. a 32% sucrose solution (SS)]. Four days later, they were again subjected to the SPT test (32% vs. 0.7% SS), and then tested on the EPM apparatus 3 days later. Following the completion of the anxiogenic profile of the model, the animals were resocialized for 72 h and then re-tested once again using the SPT (32% vs. 0.7% SS). Twenty-four hours after this final consumption, the animals were euthanized to record the weight of their adrenal glands (AG). It was found that exposure to CSI produces anhedonic-type behavior and an anxiogenic profile in adolescent male rats, as evidenced in both the SPT and EPM tests, as well as in the animals' physiological stress response. It was also demonstrated that resocialization does not reverse the anhedonic-type behavior, nor the physiological response to stress.

RESUMEN

Although medial prefrontal cortex (mPFC) is known to play important roles in social behaviors, how early social experiences affect the mPFC and its subcortical circuit remains unclear. We report that mice singly housed (SH) for 8 weeks after weaning show a social recognition deficit, even after 4 weeks of resocialization. In SH mice, prefrontal infralimbic (IL) neurons projecting to the shell region of nucleus accumbens (NAcSh) show decreased excitability compared with group-housed (GH) mice. NAcSh-projecting IL neurons are activated when GH mice encounter a familiar conspecific, which is not observed in SH mice. Chemogenetic inhibition of NAcSh-projecting IL neurons in normal mice impairs social recognition without affecting social preference, whereas activation of these neurons reverses social recognition deficit in SH mice. Our findings demonstrate that early social experience critically affects mPFC IL-NAcSh projection, the activation of which is required for social recognition by encoding information for social familiarity.

RESUMEN

Loneliness affects group-living mammals triggering a cascade of stress-dependent physiological disorders. Indeed, social isolation stress is a major risk factor for several neuropsychiatric disorders including anxiety and depression. Furthermore, social isolation has a negative impact on health and fitness. However, the neurobiological consequences of long-term chronic social isolation stress (LTCSIS) manifested during the adulthood of affected individuals are not fully understood. Our study assessed the impact of LTCSIS and social buffering (re-socialization) on the behavioural performance and social-affective brain-related proteins in diurnal, social, and long-lived Octodon degus (degus). Thereby, anxiety-like and social behaviour, and social recognition memory were assessed in male and female animals subjected to a variety of stress-inducing treatments applied from post-natal and post-weaning until their adulthood. Additionally, we evaluated the relationship among LTCSIS, Oxytocin levels (OXT), and OXT-Ca2+-signalling proteins in the hypothalamus, the hippocampus, and the prefrontal cortex. Our findings suggest that LTCSIS induces anxiety like-behaviour and impairs social novelty preference whereas sociability is unaffected. On the other hand, re-socialization can revert both isolation-induced anxiety and social memory impairment. However, OXT and its signalling remained reduced in the abovementioned brain areas, suggesting that the observed changes in OXT-Ca2+ pathway proteins were permanent in male and female degus. Based on these findings, we conclude degus experience social stress differently, suggesting the existence of sex-related mechanisms to cope with specific adaptive challenges.

RESUMEN

Resumen El Sistema de Responsabilidad Penal para Adolescentes (SRPA) en Colombia es un sistema penal diferenciado fundamentado en la resocialización, restitución de de rechos e inclusión educativa. Este artículo analiza los procesos de educación de la Fundación Hogares Claret, operario del SRPA en Santander. Es de resaltar que, el proceso educativo requiere un modelo pedagógico propio acorde al perfil de los jóvenes, así como la revisión de los criterios de selección y la calidad de los profesores y las instituciones educativas.


Abstract The Criminal Responsibility System for Adolescents (SRPA) in Colombia is a diffe rentiated criminal system based on resocialization, restitution of rights, and educa tional inclusion. This article discusses the education processes at the Hogares Claret Foundation, operator of SRPA, in Santander. It should be noted that the educational process requires its own pedagogical model according to the profile of young people, as well as the revision of the selection criteria and the quality of teachers and educational institutions.

RESUMEN

Resumen Esta investigación tuvo como objetivo analizar los efectos de la aplicación del Programa de Enriquecimiento Instrumental (PEI) de Reuven Feuerstein sobre un grupo de jóvenes infractores en proceso de resocialización de la Fundación El Faro del municipio de San José de Cúcuta, Colombia. Corresponde a un estudio cualitativo de nivel descriptivo enmarcado en la orientación epistemológica del paradigma interpretativo. En el estudio participaron diez jóvenes en proceso de resocialización con diversas características y limitaciones; para la intervención y recolección de información se utilizaron los instrumentos de relaciones virtuales, comparaciones y relaciones espaciales del PEI junto al diario de campo. Los resultados presentados desde la perspectiva cualitativa muestran un conjunto de cambios en las estructuras cognitivas de los jóvenes sujetos a intervención, es decir, sobre las funciones cognitivas y las operaciones mentales, aunque algunos factores limitaron la mediación como el consumo de sustancias psicoactivas y el ambiente del centro de rehabilitación. La evidencia permite concluir que son significativas las potencialidades del programa cognitivo y la Experiencia de Aprendizaje Mediado -EAM- como se señalan en otros estudios sobre los diferentes ámbitos de aplicación de la teoría de la Modificabilidad Estructural Cognitiva.


Abstract The objective of this research was to analyze the effects of applying Reuven Feuerstein's Instrumental Enrichment (FIE) Program to a group of juvenile offenders during a resocialization process by Fundación El Faro in the municipality of San José of Cucuta, Colombia. It corresponds to a qualitative, descriptive study framed within the epistemological orientation of the interpretative paradigm. Ten young people with various characteristics and limitations participated in the resocialization process. Virtual relationship instruments, comparisons and FIE spatial relationships were used in the intervention and for information collection, along with the field log. The results presented from a qualitative perspective show a set of changes in the cognitive structures of young people subject to intervention. That is, cognitive functions and mental operations changed, although some factors limited mediation, such as psychoactive substance consumption and the environment within the rehabilitation center. The evidence allows concluding that the Mediated Learning Experience (MLE) and the program's cognitive potentials are significant, as indicated in other studies on the different environments in which the Structural Cognitive Modifiability Theory is applied.

RESUMEN

The objective of this study was to gain insights into how victims use their visual attention to determine the sincerity of an offender's apology during simulated victim-offender mediation. We hypothesized that the victims' visual attention (gaze fixation duration) would be focused more on the offender's upper (than lower) face area, especially the eyes and the eyebrows, to infer the degree to which the offender suffers, takes responsibility, and has empathy for the victim. In turn, we expected these inferences to positively predict the perceived sincerity of the apology. Additionally, we took into account the victims' a priori expectations regarding the sincerity of the apology and (positive) attitudes toward resocialization programs (ARPs). We expected both variables to enhance the above proposed process through which victims determine the sincerity of the apology. Fifty-eight students took the victim's role in a fictitious crime scenario and watched a video in which the offender offered a remorseful apology. We obtained eye tracking data to determine the participants' fixation and attention distribution. As expected, the participants' gaze fixated significantly longer on the upper face. The results also showed that their prior expectations, positive ARPs, and inferences of suffering and responsibility taking after the apology all positively predicted the perceived sincerity. However, unexpectedly, gaze duration was not directly associated with these inferences. The fixation duration on the upper face instead appeared to moderate how ARPs predicted inferences of responsibility taking. More concretely, the exploratory path model analyses revealed that when the participants had more positive a priori ARPs, the longer they focused on the offender's eyes and eyebrows and the more they concluded that he took responsibility for his actions (which in turn predicted more sincerity). However, for those with relatively negative ARPs, it was the other way around: the more they focused on the eyes and the eyebrows, the stronger they inferred that the offender did not take responsibility (which predicted less sincerity). Our findings demonstrate the vital role of the victims' a priori attitudes, expectations, and eye gaze behavior in understanding the reception and the evaluation of offenders' apologies. This study also suggests how novel technology can be used to investigate gaze behavior in the field of victim-offender mediation.

RESUMEN

One of the concerns that always remain for the repentant criminal is the condition for his return to society. This concern may be so strong and effective that the criminal may seclude from the society due to the fear of its consequences and may return to crime. Therefore, paying attention to eliminating the social effect of the criminal conviction of criminals can return security to society and return the repentant criminals to normal life. So, all military and social institutions are effective in the re-socialization, in such a way that the re-socialization of criminals requires the provision of social platforms that starts with their own family and expands to society. The main concern of this research is how we can provide the favorable conditions for the re-socialization of repentant criminals that effectively realize the socialization goals. The Islamic Penal Code initiatives in 2013, despite the gaps in this regard, partly help to achieve such goals, but they are not enough. Therefore, the present article focused on the criminals' re-socialization and tried to raise the criminals' re-socialization both socially and criminally. The method was descriptive analytical. The result showed that the Islamic Penal Code, adopted in 2013 on the period of the subsequent effects, needs to be reformed, and the effective social institutions should be raised orderly in such a case.

RESUMEN

PURPOSE: The purpose of this paper is to evaluate the use of a phototherapeutic technique called "Talking Pictures" within the forensic setting. This approach involves the use of a set of photographs to facilitate clients' disclosure, self-growth and promote the development of positive self-narratives. The use of art therapies and the construction of adaptive identity narratives have been proven to support desistance and increase resocialization in the prison population. DESIGN/METHODOLOGY/APPROACH: A 42-year-old Italian male offender was met for six therapy sessions and invited to talk about his past, present and future through the use of photographs. Session transcripts were analysed using the software for linguistic analysis T-LAB. FINDINGS: Results show a progression in the language used during the sessions: in the beginning the client uses a denotative language with many concrete nouns and no emotional words, in subsequent sessions his speech begins to assume more symbolic connotations and emotional words are used to describe past traumas as well as to find new meanings to present events. Moreover, the fixity of the client's self-image is contrasted with the emergence of new sides to his personality encompassing agency and self-worth. RESEARCH LIMITATIONS/IMPLICATIONS: The study is based on a single case, therefore results cannot be generalised to the prison population; moreover, the absence of any follow-up and standardized measurements of the client's progression should be addressed by future research by both involving larger samples and including follow-up and quantitative measures of the study results. PRACTICAL IMPLICATIONS: The paper provides details on an innovative technique that might be used to explore the offenders' goods and values and to develop truly redemptive rehabilitation programmes. ORIGINALITY/VALUE: This paper adds to the scant literature on phototherapy in prisons and connects it with a reflection on desistance indicating that phototherapeutic interventions might be used to promote positive self-narratives, thus increasing desistance.

RESUMEN

Social isolation (SI) has detrimental effects on human and animal cognitive functions. In particular, acute isolation in adult mice impairs social recognition memory (SRM). Previous accounts of this impairment have focused primarily on memory consolidation. However, the current study suggests that impaired SRM results from enhanced forgetting. SI accelerates SRM decay without affecting memory formation. The impairment is caused by elevated Rac1 activity in the hippocampus. Using adeno-associated-virus-based genetic manipulation, we found that inhibition of Rac1 activity blocked forgetting of SRM in isolated adult mice, whereas activation of Rac1 accelerated forgetting in group-housed mice. Moreover, resocialization reversed the accelerated forgetting following isolation in correlation with suppression of Rac1 activity. In addition, accelerated long-term potentiation (LTP) decay in isolated mice brain slices was rescued by inhibition of Rac1 activity. Taken together, the findings lead us to conclude that social memory deficits in isolated mice are mediated by enhanced Rac1-dependent forgetting.

RESUMEN

Resumen El presente artículo tiene como objetivo analizar el impacto negativo que guarda la política criminal y los sistemas penitenciarios de Colombia, en especial frente aquellas personas que han cometido delitos relacionados con el narcotráfico, cuya persecución altamente represiva contra la fabricación, posesión o tráfico de estupefacientes, no ha tenido ningún efecto significativo en reducir las estructuras delictivas que se han generado en torno al negocio de narcóticos. Lo que ha generado, es un aumento de la población carcelaria, personas que presentan una alta probabilidad de recaída cuando recobran su libertad, -reincidencia delictiva-, motivada por diferentes factores; pero especialmente por el tiempo y la influencia negativa que les ha generado la prisión, ello derivado de las fallas estructurales dentro de las prisiones, lo cual frena la prevención especial positiva, a falta de un tratamiento de resocialización.


Abstract The objective of this work is to analyze the negative impact that the criminal policy and the Colombian penitentiary systems hold, mainly against people who have committed drug trafficking offences, whose highly repressive persecution against the manufacture, possession or narcotic drugs traffic, have not got any significant effect in criminal structures reduction. These criminal structures have been produced on the narco-trafficking business. This has generated an increase in the prison population. These people have a high probability of relapse upon release from prison -criminal recidivism-; it is incited by different factors, particularly the time and the negative influence of prison on them, due to structural problems within the prisons which slow down the special positive prevention, in the absence of a resocialization treatment.


Resumo O objetivo deste trabalho é analisar o impacto negativo da política criminal e dos sistemas prisionais da Colômbia, em especial em relação àquelas pessoas que têm cometido crimes vinculados ao narcotráfico, cuja perseguição, altamente repressiva contra a fabricação, posse ou tráfico de entorpecentes, não tem tido nenhum efeito significativo na redução das estruturas delitivas do negócio dos narcóticos. No entanto, verifica-se um aumento da população prisional, composta por pessoas que apresentam uma probabilidade alta de reincidir quando recobram a liberdade - reincidência delitiva -, motivada por diferentes fatores, sobretudo pelo tempo e pela influência negativa causada pela prisão, devido às falhas estruturais dentro das cadeias, que impedem a prevenção especial positiva, a falta de um tratamentode ressocialização.

RESUMEN

AIM: To assess the effectiveness of a psycho-educational program in patients with schizophrenia. MATERIAL AND METHODS: A psycho-educational program, which included 12 sessions (1.5h each session), was administered to 30 patients (23 women and 7 men), aged under 40 years (90%). The effectiveness of the program was estimated by comparing the proportion of hospitalizations within 12 months after its implementation, as well as by the average duration of hospitalizations. RESULTS AND CONCLUSION: There was a decrease in relapses of mental disorders requiring hospitalization (from 4.9 to 3.8) and a reduction in the length of hospital stay for treatment (from 67 to 35 days). Psychoeducation programs can and should be implemented in practice of psychiatric services as an effective solution when dealing with a patient with schizophrenia and his family.

RESUMEN

INTRODUCTION: Memory deficit is an important issue in some psychiatric diseases either as a primary symptom or as a comorbid symptom. Factors that determine the decline or improvement of memory are an important subject to reduce the severity of these diseases. METHODS AND MATERIALS: In this study, 32 male Sprague-Dawley rats were randomly divided into 4 experimental groups: social (control), isolation, resocialization for 3 days, and resocialization for 7 days. Isolation occurred for 14 days. Resocialization groups were resocialized for 3 or 7 days after isolation. In the social group, there was no intervention with normal socializing among the rats. In the isolation group, rats were isolated with no resocialization. In all 4 groups, after performing the Y-maze, the rats' brains were removed to assess oxidative stress status in the hippocampus and prefrontal cortex. RESULTS: Y-maze performance improved after 3 and 7 days of resocialization. However, oxidative stress status for malondialdehyde, glutathione and nitrite/nitrate returned to normal levels except in 2 experiments after 7 days of resocialization. In addition, in 2 experiments, just glutathione in the prefrontal cortex and nitrite/nitrate in the hippocampus after 3 days of resocialization improved. CONCLUSIONS: A return to normal levels in all types of antioxidant markers in the resocialization groups is not the only factor for improving memory deficits resulting from isolation.
