Family religiosity and climate: the protective role of personal interiorized religiosity in deviance propensity among justice-involved juveniles.

According to the literature, religious commitment could be a protective factor against dangerous behaviors, such as criminal offending, unsafe sex, and substance use. Our study aims to investigate the influence of Family Religiosity and climate on anger dysregulation and deviance propensity in a sample of 214 justice-involved boys from Italian Youth Detention Centers (range 14-25). The sample was divided into religious (n = 102) and non-religious (n = 112) justice-involved juveniles. Participants filled in the following questionnaires: Deviant Behavior Questionnaire, Aggression Questionnaire, Family Communication Scale, Moral Disengagement Scale, and the Multidimensional Scale of Perceived Social Support. We used a partial least square structural equation modeling (PLS_SEM) method to build our model and we found that Family Religiosity was positively associated with Family Climate which was negatively associated with Anger Dysregulation and Deviance Propensity, and Anger Dysregulation was positively related to Deviance Propensity. The multigroup analysis confirmed that for justice-involved juveniles who interiorized religious discipline and beliefs, Family Religiosity showed a positive association with Family Climate, which had a negative relationship with Anger Dysregulation, which strongly predicted Deviance Propensity. This result could be useful to promote new development goals and preventive activities and interventions based on positive religiosity values in juveniles' behavior.

Making a Bad Situation Worse: Current and Potential Unintended Consequences of Juvenile Registration for Sexual Offences.

Within the US, children and adolescents who engage in sexually abusive behavior are often subjected to sex offender registration and notification requirements, which contribute to stigmatization and forfeiture of their civil rights without empirical basis (Lancaster, 2011; Pickett et al., 2023; Zilney & Zilney, 2009). To date, 39 states subject children with adjudicated sexual offenses to sex offender registration requirements, with most recent estimates revealing that approximately 200,000 youth have been placed on sex offender registries within the US and many are now on the registry as adults (Pickett et al., 2020). This severe response-by both members of the public and policymakers-toward children who engage in inappropriate sexual behavior is imposed upon children and adolescents with adjudicated sexual offenses in an effort to meet goals of reducing sexual violence and increasing community safety. Within the current discourse, we review the history of registration and notification practices for adolescents with sexual offenses, describe what registration and notification policies entail, and then present empirical and theoretical evidence of the harmful outcomes associated with implementation of registration and notification requirements for sexual offenses. Thus, the predominant aim of this discourse is to encourage thoughtful and critical examination of registration and notification policies and their iatrogenic impacts.

The incorporation of strontium and barium into the otoliths of the flounder Paralichthys olivaceus at early life stages demonstrates resilience to ocean acidification.

Ocean acidification could modify the bioavailability and chemical properties of trace elements in seawater, which could affect their incorporation into the calcareous structures of marine organisms. Fish otoliths, biomineralized ear stones made by aragonite, are suspended within the endolymph fluid of teleosts, indicating that the elemental incorporation of otoliths might also be susceptible to ocean acidification. In this study, we evaluated the combined effects of CO2-induced ocean acidification (pH 8.10, 7.70, and 7.30, corresponding to ocean acidification scenarios under the representative concentration pathway 8.5 model as projected by the Intergovernmental Panel on Climate Change) and water elemental concentrations of strontium (Sr) and barium (Ba; low, medium, and high) on elemental incorporation into otoliths of the flounder Paralichthys olivaceus at early life stages. Our results revealed that the elemental incorporation of Sr and Ba into otoliths was principally dependent on the corresponding water elemental concentrations rather than on ocean acidification. Moreover, the partition coefficients (DMe) of Sr and Ba may stabilize after dynamic equilibrium is reached as the water elemental concentration increases, but are not affected by ocean acidification. Therefore, the incorporation of Sr and Ba into otoliths of the flounder at early life stages may not serve as an effective indicator of ocean acidification. In other words, the findings suggest that ocean acidification does not impact the incorporation of Sr and Ba incorporation into otoliths when tracing the temperature or salinity experiences of the flounder. Our findings will provide new knowledge for understanding the potential ecological effects of ocean acidification on the recruitment dynamics of fish species.

Exploring the Effects of Graphene-Based Nanoparticles on Early Salmonids Cardiorespiratory Responses, Swimming and Nesting Behavior.

Graphene-based nanomaterials are exceptionally attractive for a wide range of applications, raising the likelihood of the release of graphene-containing nanoparticles into aquatic environments. The growing use of these carbon nanomaterials in different industries highlights the crucial need to investigate their environmental impact and evaluate potential risks to living organisms. The current investigation evaluated the nanotoxicity of graphene (nanoflakes) and graphene oxide (GO) nanoparticles on the cardiorespiratory responses (heart rate, gill ventilation frequency), as well as the swimming and nesting behavioral parameters of early stage larvae and juvenile salmonids. Both short-term (96 h) and long-term (23 days) exposure experiments were conducted using two common species: brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss). The findings demonstrated notable alterations in fish nesting behavior, swimming performance, and cardiorespiratory functions, indicating the potential toxicity of nanoparticles. This impact was observed at both physiological and whole-organismal levels in salmonids at early stages. Future investigations should explore different types of nanocarbons and their potential enduring effects on fish population structure, considering not only individual survival but also broader aspects of development, including feeding, reproductive, and other social dynamics.

Toxicological impacts of microplastics on virulence, reproduction and physiological process of entomopathogenic nematodes.

Microplastics have emerged as significant and concerning pollutants within soil ecosystems. Among the soil biota, entomopathogenic nematodes (EPNs) are lethal parasites of arthropods, and are considered among the most effective biological agents against pests. Infective juveniles (IJs) of EPNs, as they navigate the soil matrix scavenging for arthropod hosts to infect, they could potentially encounter microplastics. Howver, the impact of microplastics on EPNs has not been fully elucidated yet. We addressed this gap by subjecting Steinernema feltiae EPNs to polystyrene microplastics (PS-MPs) with various sizes, concentrations, and exposure durations. After confirming PS-MP ingestion by S. feltiae using fluorescent dyes, we found that the PS-MPs reduced the survival, reproduction, and pathogenicity of the tested EPNs, with effects intensifying for smaller PS-MPs (0.1-1 µm) at higher concentrations (105 µg/L). Furthermore, exposure to PS-MPs triggered oxidative stress in S. feltiae, leading to increased reactive oxygen species levels, compromised mitochondrial membrane potential, and increased antioxidative enzyme activity. Furthermore, transcriptome analyses revealed PS-MP-induced suppression of mitochondrial function and oxidative phosphorylation pathways. In conclusion, we show that ingestion of PS-MPs by EPNs can compromise their fitness, due to multple toxicity effects. Our results bear far-reaching consequences, as the presence of microplastics in soil ecosystems could undermine the ecological role of EPNs in regulating pest populations.

Morphological Ontogeny, Ecology, and Biogeography of Fuscozetes fuscipes (Acari, Oribatida, Ceratozetidae).

The systematic status of Fuscozetes Sellnick, 1928, is not clear in the literature. Therefore, the morphological ontogeny of F. fuscipes (C.L. Koch, 1844), the type species of this genus, was investigated and compared with its congeners in this study, and a new diagnosis of Fuscozetes is given. The juveniles of F. fuscipes are light brown, with a brown prodorsum, sclerites, epimeres, and legs. In all juveniles, a humeral organ and a humeral macrosclerite are present. The gastronotum of the larva has 12 pairs of setae (h3 is present), whereas the nymphs have 15 pairs. In the larva, the gastronotal shield is weakly developed, and most gastronotal setae are short except for a slightly longer h2. Most of the gastronotal setae are inserted on the microsclerites except for h3, and several other macrosclerites and many microsclerites are present on the hysterosoma. In the nymphs, the gastronotal shield is well developed, with 10 pairs of setae (d-, l-, and h-series, and p1), and setae p2 and p3 are located on a large posteroventral macrosclerite. In all the instars, femora I and II are oval in cross-section, without a large ventral carina. Mitochondrial COI sequence data revealed a deep split between the Nearctic and Palearctic populations of F. fuscipes, and a less, but significant, divergence within each continent. These strong geographical barriers were contrasted with multiple cases of shared haplotypes over long distances in the Palearctic, indicating high migration rates in modern times.

Repeatability of measures of behavioral organization over two years in captive infant rhesus macaques, Macaca mulatta.

Individual differences of infant temperament have been associated with future health outcomes that provide explanatory power beyond adult personality. Despite the importance of such a metric, our developmental understanding of personality-like traits is poor. Therefore, we examined whether young primates show consistency in personality traits throughout development. We replicated a Biobehavioral Assessment (BBA) at three time periods: 3-4 months, 1 year, and 2 years of age in 47 rhesus macaque (Macaca mulatta) subjects from large mixed-sex outdoor social housing units at the California National Primate Research Center. We report results for tests focused on responses and adaptation to the temporary separation and relocation, responses to a threatening stimulus, and ratings of overall temperament. We found consistently repeatable associations in measures of Emotionality; these associations were stronger in males, but also present in females, and broadly consistent between Years 1 and 2. We also explored whether behavioral responses to this experimental relocation might be influenced by their experience being relocated for other reasons (i.e., hospitalizations) as individuals' responses might be influenced by similar experiences to the BBA procedure. Only locomotion, during one of the assessments, was associated with past hospitalization events. Overall, repeatability in Emotionality-associated behaviors was evident across the 2 years, in both sexes. We did, however, find evidence of the emergence of sex differences via differentiated expression of behavioral responses during the BBA. We emphasize that there is likely contextual nuance in the use of these BBA factor-associated behaviors. Further research is required to determine whether and how shifts occur in underlying factor structure and the expression of associated behaviors.

Coach-athlete relationships and life skills development among Brazilian handball players: A prospective study / Relaciones entrenador-atleta y desarrollo de habilidades para la vida entre jugadores brasileños de balonmano: un estudio prospectivo

This study was to examine the prospective associations between coach-athlete relationship (CAR) and life skills development in youth handball players. This study employed a longitudinal research design. A total of 78 male handball players completed the Life Skills Scale for Sport and the Coach-Athlete Relationship Questionnaire over three waves of data collection: start of the season; midseason and end of the season. Data were analyzed using multivariate analysis of variance Pearson’s Correlation and Linear Multiple Regression (p<.05). The findings indicated the three dimensions of CAR seem to have higher effect on life skills subscales as the season progressed (i.e., higher effect on life skills at T3 compared to T2 and T1). Commitment and Complementarity were positively associated with several life skills subscales at all three timepoints. Results suggest that the quality of the CAR is an important determinant for the de-velopment of life skills in youth handball players across the sports season. (AU)

Este estudio tuvo como objetivo examinar las posibles asociaciones entre la relación entrena-dor-atleta (CAR) y el desarrollo de habilidades para la vida en jugadores juveniles de balon-mano. Este estudio empleó un diseño de investigación longitudinal. Un total de 78 jugadores masculinos de balonmano completaron la Escala de Habilidades para la Vida Deportiva y la Es-cala de Entrenadores. Cuestionario sobre la relación con los atletas en tres oleadas de recopi-lación de datos: inicio de la temporada; mitad de temporada y final de temporada. Los datos se analizaron mediante análisis multivariado de varianza, correlación de Pearson y regresión lineal múltiple (p<0,05). Los hallazgos indicaron que las tres dimensiones de CAR parecen te-ner un mayor efecto en las subescalas de habilidades para la vida a medida que avanzaba la temporada (es decir, un mayor efecto sobre las habilidades para la vida en T3 en comparación con T2 y T1). El compromiso y la complementariedad se asociaron positivamente con varias subescalas de habilidades para la vida en los tres momentos. Los resultados sugieren que la ca-lidad del CAR es un determinante importante para el desarrollo de habilidades para la vida en jugadores juveniles de balonmano a lo largo de la temporada deportiva.

Teaching-Learning Process in a Juvenile Delinquents' Correction Center: Challenges in Focus.

A case study was employed to explore the effectiveness of the teaching-learning process in the center. Active participants in the process and the head of the juvenile correction center were purposely selected as informants. Semi-structured interviews and classroom observations were used to gather relevant data. Data analysis and data collection were conducted simultaneously. The study revealed that teachers either use corporal punishment or are laissez-faire when students show misbehavior. They often use the lecture method. Neither teachers nor students are motivated to take part in curricular and extra-curricular activities. Lack of adequate meals, absence of different facilities, mistreatment from teachers and guardians, and lack of appropriate counseling service make students develop hatred for the center. Moreover, the curriculum rarely addresses students' unique behavior and education needs. Thus, it is less likely to realize the intended objective of the center in such a situation.

Fish Playpens: Method for Raising Individual Juvenile Zebrafish on a Recirculating System for Studies Requiring Repeated Measures.

Even though many experimental approaches benefit from tracking individual juvenile animals, there is yet to be a commercial zebrafish rack system designed to accomplish this task. Thus, we invented playpens, an acrylic, and screen container, to raise 12 individual zebrafish juveniles per standard 10 L tank on an existing recirculating fish system. During a week-long experiment, fish raised in playpens grow to the same size as conventionally raised juveniles.

Assessing the Effectiveness of a Specialized, Field-Based Treatment Program for Youth Who Have Committed Sexual Offenses in an Australian Jurisdiction.

This study provides an evaluation of recidivism outcomes for a specialized, field-based treatment program for youth who perpetrate sexual offenses in an Australian jurisdiction. Using survival analyses, recidivism outcomes for the treatment group (n = 200), who were followed for an average of 5.07 years (SD = 3.13), were contrasted with a sample of sexually offending youth who were either referred but not accepted or not referred to the program (n = 295). Rates of sexual recidivism were low and not significantly different between the groups (9.5% for treated and 10.8% for untreated). Unadjusted Cox regression results indicated that the treated group were less likely to violently recidivate compared to the untreated group (HR = 1.41, 95% CI [1.01, 1.96]), but this effect became nonsignificant when controlling for offense history covariates (HR = 1.22, 95% CI [0.87, 1.72]). Both groups exhibited high rates of nonsexual offending during the follow-up period, and treatment factors including clinician-rated success, were found to be associated with a lower frequency of reoffending after treatment. Findings highlight important considerations for both practice and research. First, findings suggest the need for specialized programs to ensure factors associated with general recidivism are also addressed in treatment; second, findings reinforce potential utility for clinician-rated and structured assessments to inform treatment planning and outcomes. Finally, the findings raise the importance of appropriate comparison groups when designing evaluation studies, to accurately inform policy and practice.

Morphological Ontogeny and Ecology of a Common Peatland Mite, Nanhermannia coronata (Acari, Oribatida, Nanhermanniidae).

Nanhermannia coronata Berlese, 1913, is a common and abundant oribatid species in peatlands but can be easily mistaken for N. sellnicki Forsslund, 1958, as an adult. Therefore, the identity of adults of N. coronata from several sites in Norway and Ireland was supported by the COI sequence data, and based on this material, the morphological ontogeny of this species is described and illustrated to highlight the differences between N. coronata and N. sellnicki. In all juvenile stages of N. coronata, the bothridial seta is absent, but two pairs of exobothridial setae are present, including short exp and exa reduced to its alveolus. In the larva, seta f1 is setiform, but in the nymphs, it is reduced to its alveolus. Most prodorsal and gastronotal setae of larva are short, and of nymphs they are long. In all instars, the leg segments are oval in cross section and relatively thick, and many setae on tarsi are relatively short, thick and conical, except for longer apical setae. Seta d accompanies solenidion σ on all genua, φ1 on tibia I and φ on other tibiae. We found some morphological characters that clearly differentiate N. coronata from N. sellnicki, like the number of setae on femora of adults and tritonymphs, the shape of insertions of prodorsal seta in and all gastronotal and adanal setae of juveniles; in N. sellnicki, these setae are inserted in small individual depressions, whereas in N. coronata, these depressions are absent. Our ecological observations confirm a common occurrence of N. coronata in raised bogs, a high percentage of juvenile stages in its populations and a preference of this species for humid microhabitats, whereas N. sellnicki is less common than N. coronata and occurs in drier habitats.

Limited prosocial emotions (LPE) specifier in conduct disorder and offending behavior: findings from a 10-year prospective longitudinal study of juveniles in residential care.

BACKGROUND: Since the introduction of the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5, a limited prosocial emotion (LPE) specifier has been added to the conduct disorder (CD) diagnosis in addition to the age of onset specifier. It was suggested that this would identify a subgroup with severe antisocial and/or aggressive behavior with serious current and future (mental health) impairment. Research in recent years has shown that this is indeed a subgroup with severe antisocial behavior; however, mental health problems do not appear to differ from those of youth with CD without LPE. Most research to date has been cross-sectional. However, longitudinal research is urgently needed to better understand the predictive value of the LPE specifier. The aim of the current longitudinal study is to examine future offending behavior of youth with CD with compared to youth without the LPE specifier. In addition, the predictive value of the categorical LPE specifier and the dimensional LPE score will be examined beyond factors that are strongly associated with future offending (i.e., gender, age, and prior offending). METHODS: Adolescents and young adults (12-25) with CD (assessed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version [K-SADS-PL]) with (N = 61) and without (N = 75) the LPE specifier (assessed with the Callous-Unemotional [CU] dimension of the Youth Psychopathic traits Inventory [YPI]) (in line with Jambroes et al., 2016) were compared on sociodemographic characteristics, mental health problems and offending behavior. Future (general and violent) offending was based on official conviction data. RESULTS: Our results showed that youth with CD with and without the LPE specifier did not differ in self-reported and informant-reported mental health problems. However, youth with CD with the LPE specifier showed more offending behavior and personality pathology at baseline. In addition, the categorical LPE specifier was associated with future general offending, but not with future violent offending. The dimensional LPE score was associated with both future general and violent offending. However, after adjustment for gender, age, and prior delinquency, these associations disappeared, with the exception of the association between the dimensional LPE score and violent offending, which remained significant even after controlling for gender, age, and prior violent offending. DISCUSSION: In conclusion, there seems to be evidence of a relationship between limited prosocial emotions and future offending behavior in youth with CD. This relationship, however, should not be overestimated, as there are other (static) factors (e.g. gender and prior offending behavior) that also have a strong influence on future (violent) offending behavior. Still, from a clinical point of view, a dynamic factor like prosocial emotional skills is a good focus for reducing the risk of future offending behavior.

Hair and plasma cortisol throughout the first 3 years of development in infant rhesus macaques, Macaca mulatta.

Cortisol expression has been demonstrated to have variation across development in rhesus macaques (Macaca mulatta). There exists contradictory evidence for the nature of this change, and age at which it occurs, across biological sample types. Consequently, we lack a cohesive understanding for cortisol concentrations across the development of a major human health translational model. We examined hair cortisol concentrations over the first 3 years of life for 49 mother-reared infant macaques from mixed-sex outdoor units at the California National Primate Research Center. For 48 of these subjects at infancy, 1 year, and 2 years, we obtained plasma cortisol samples for response to a stressor, adjustment to prolonged stress, and response to dexamethasone injection. Hair cortisol concentrations decreased dramatically between 3 and 10 months, followed by relative stability up to the final sampling event at around 34 months of age. Plasma cortisol showed within-year consistency, and consistency between infancy and year 1. We document variability in the infant plasma cortisol samples, especially in percent change between samples 1 and 2. Our plasma cortisol results indicate that infants possess the physiological capacity to effectively inhibit the release of cortisol when stimulated, as effectively as later responses in juveniles. Age-related changes in hair cortisol parallel findings indicating a large decline in the weeks following postparturation.

Living Situation of Juveniles After Secure Residential Treatment: Exploring the Role of Family Centeredness, Child, and Family Factors.

To promote the return of juveniles to a home-like environment (e.g. living with (foster)parents) after secure residential treatment (SRT), it is important to know which factors are related to this outcome. The current study examined which characteristics of the juvenile, family, and SRT, including family centeredness and use of systemic interventions, are related to the living situation after discharge. For 259 juveniles (mean age 15.82 years, 127 girls) in SRT and their parents, questionnaires were administered at admission, discharge, and 6-months follow-up. Furthermore, information about the living situation before and after SRT was gathered. Higher likelihood of living in a home-like setting after SRT correlated with more furlough moments with parents, receiving a systemic intervention, and a shorter duration of the SRT. Systemic interventions during SRT and spending furlough moments with parents may have a positive impact on returning to a home-like situation after SRT for juveniles.

Evaluation of Post-Larval Diets for Indoor Weaned Largemouth Bass (Micropterus salmoides).

This study aimed to evaluate different commercial diets (Otohime C1, Aller Futura (AF), Biomar Inicio Plus (BIP)) and one experimental feed (EF) in terms of their effectiveness as post-larval diets for indoor weaned largemouth bass, LMB (Micropterus salmoides). Key variations in the content of nutritive values were monounsaturated fatty acid (MUFA) and highly unsaturated FA (HUFA) ω3. Fish were fed with one of four tested diets from the 33rd to the 40th day post-hatch (DPH). Biometric indices, digestive enzyme-specific activities, thyroid hormone status, and mRNA expression of genes coding for skeleton, neuron, and muscle growth were analyzed. The lowest skeletal deformity rate and highest survival among the treatments were seen in BIP-fed fish. Dietary lipids, with an appropriate balance between MUFA and polyunsaturated FA (PUFA), alongside amino acid balance, were shown to be the main contributors to the growth of the skeleton and/or fish survival. On the other hand, fish growth is correlated with fish digestive capacity and feed moisture percent rather than feed quality. Unexpectedly, BIP-fed fish were attributed with the lowest expression of skeleton differentiation markers, which may reflect the sacrifice of scale and/or cranium growth at the expense of somatic growth. This study highlights the role of non-marine ingredients in the nutrition of post-larval LMB.

Juvenile waiting stage crown-of-thorns sea stars are resilient in heatwave conditions that bleach and kill corals.

The juveniles of predatory sea stars can remain in their recruitment-nursery habitat for some time before their ontogenetic shift to the adult habitat and diet. These small juveniles are vulnerable to a range of factors with their sensitivity amplified by climate change-driven ocean warming. We investigate the thermal tolerance of the waiting stage herbivorous juveniles of the keystone coral predator, the crown-of-thorns sea star (COTS, Acanthaster sp.), in context with the degree heating weeks (DHW) model that predicts coral bleaching and mass mortality. In temperature treatments ranging from +1 to 3°C in prolonged heatwave acclimation conditions, the juveniles exhibited ~100% survival in DHW scenarios that trigger coral bleaching (4 DHW), resulting in mass mortality of corals (8 DHW) and extreme conditions well beyond those that kill corals (12 DHW). This indicates that herbivorous juvenile COTS are far more resistant to heatwave conditions than the coral prey of the adults. The juveniles exhibited higher activity (righting) and metabolic rate after weeks in increased temperature. In separate acute temperature experiments, the upper thermal limit of the juveniles was 34-36°C. In a warming world, juvenile COTS residing in their coral rubble nursery habitat will benefit from an increase in the extent of this habitat due to coral mortality. The juveniles have potential for long-term persistence as herbivores as they wait for live coral to recover before becoming coral predators, thereby serving as a proximate source of COTS outbreaks on reefs already in a tenuous state due to climate change.

Maternal Investment Fosters Male but Not Female Social Interactions with Other Group Members in Immature Wild Spider Monkeys (Ateles geoffroyi).

In several species, individuals form long-lasting social relationships with other group members, which provide them with important fitness benefits. In primates, patterns of social relationships are known to differ between sexes, but little is known about how these differences emerge through development or the role that mothers might have in this process. Here, we investigated how sex differences in social behaviour emerge during the first six years of primate life and how sex-biased maternal investment can foster immatures' social development and social interaction with other group members. For this purpose, we observed 20 males and females aged between zero and six years in a wild group of spider monkeys (Ateles geoffroyi) that was male-philopatric and, therefore, expected to show sex-biased maternal investment. Our results showed no sex difference in the social development of offspring with regards to body contact and grooming, but the probability of play was rather constant throughout age for females, whereas, for males, it became higher than females around two years of age, peaking between three and four years of age. Moreover, we found differences between female and male immatures in the importance of maternal investment (which included the time mothers spent nursing, carrying, grooming, touching and playing with their offspring) for their social integration in the natal group. In particular, maternal investment increased the probability of playing with other group members for sons, but not for daughters. Our findings suggest that mothers, through sex-biased maternal investment, might have a crucial function in the social development of spider monkeys, fostering the abilities that young offspring need to thrive as adults. By shedding light on maternal investment and social development in a still understudied primate species, these findings contribute to understanding the evolutionary roots of human maternal care and social development.

Academic Motivation of Incarcerated Juveniles From the Perspective of Self-Determination Theory: A Multiple Case Study in Kosovo Context.

This qualitative (multiple case) study investigated incarcerated juveniles' experiences of being enrolled in an educational institution outside the correctional facility, and how this impacted their motivation, well-being, life satisfaction, and future social integration. Self-determination theory was used to understand how youth experienced fulfillment of their psychological needs (i.e., autonomy, competence, and relatedness). Results showed that the need for autonomy and competence were gradually met by education, whereas the need for relatedness was primarily fulfilled through relationships within the existing social network instead of through relationships with peers in the education setting. Reluctance to become acquainted with peers in the education setting may be explained by feelings of self-stigmatization. We conclude that attending education of juveniles outside prison may contribute to their future perspective and rehabilitation, in particular if sufficient attention is paid to opportunities for meaningful contact with (prosocial) fellow students outside the correctional facility.

Impacts of acute and chronic suspended solids exposure on juvenile freshwater mussels.

Construction activities may affect adjacent water systems by introducing increased levels of suspended solids into the water body and may subsequently affect the survival and growth of freshwater mussels. We tested three sediment types from sites in Missouri, including Spring River sediment (SRS), Osage River bank clay soil (ORC), and quarried limestone from Columbia (LMT). We prepared series of suspensions of each sediment with total suspended solids concentrations ranging from 0 to 5000 mg/L. Juveniles from three mussel species, Fatmucket (Lampsilis siliquoidea), Arkansas Brokenray (Lampsilis reeveiana), and Washboard (Megalonaias nervosa) were exposed to these suspensions in both acute (96-h) and chronic (28-d) tests. No clear impact on survival was observed from the acute or chronic exposures, but chronic test showed that juvenile mussels' growth was strongly affected. Interestingly, growth was enhanced at lower levels of SRS and ORC (≤500 mg/L, p < 0.05), and the juvenile mussels exposed to 500 mg/L SRS exhibited approximately 60 % more dry weight than those reared in the control. LMT did not enhance growth. Growth was slowed by high concentrations (>1000 mg/L) of all three sediments, implying that high suspended solids levels could reduce survival in the long term. Our findings may help to inform regulations and guidelines for construction activities to minimize adverse effects on juvenile mussels.
