Victims of child abuse and neglect are at an increased risk of involvement with the juvenile justice and adult correctional systems. Yet, little is known about the continuation and trajectories of offending beyond initial contact with law enforcement. Neglect likely plays a critical role in continued offending as parental monitoring, parental rejection and family relationships are instrumental in explaining juvenile conduct problems. This study sought to determine whether neglect is associated with recidivism for moderate and high risk juvenile offenders in Washington State. Statewide risk assessments and administrative records for child welfare, juvenile justice, and adult corrections were analyzed. The sample was diverse (24 % female, 13 % African American, 8 % Hispanic, 5 % Native American) and included all moderate and high risk juvenile offenders screened by juvenile probation between 2004 and 2007 (n = 19,833). Official records from child protection were used to identify juvenile offenders with a history of child neglect and to identify juvenile offenders with an ongoing case of neglect. Event history models were developed to estimate the risk of subsequent offending. Adolescents with an ongoing case neglect were significantly more likely to continue offending as compared with youth with no official history of neglect. These findings remain even after controlling for a wide range of family, peer, academic, mental health, and substance abuse covariates. Interrupting trajectories of offending is a primary focus of juvenile justice. The findings of the current study indicate that ongoing dependency issues play a critical role in explaining the outcomes achieved for adolescents in juvenile justice settings. The implications for improved collaboration between child welfare and juvenile justice are discussed.

While researchers have found that African American youth experience higher levels of juvenile justice involvement at every system level (arrest, sentencing, and incarceration) relative to their other ethnic counterparts, few studies have explored how juvenile justice involvement and number of contacts might be correlated with this broad range of problems. A convenience sample of 638 African American adolescents living in predominantly low-income, urban communities participated in a survey related to juvenile justice involvement. Major findings using logistic regression models indicated that adolescents who reported juvenile justice system involvement versus no involvement were 2.3 times as likely to report mental health problems, substance abuse, and delinquent or youth offending behaviors. Additional findings documented that the higher the number of juvenile justice system contacts, the higher the rates of delinquent behaviors, alcohol and marijuana use, sex while high on drugs, and commercial sex. These findings suggest that identifying and targeting youth who have multiple juvenile justice system contacts, especially those in low-resourced communities for early intervention services, may be beneficial. Future research should examine whether peer network norms might mediate the relationships between juvenile justice involvement and youth problem behaviors. PMID:28966415

In 1982 the NPPC included in its Fish and Wildlife Program a measure that called for studies ''... to investigate juvenile salmon and steelhead losses to predators while these fish are migrating through Columbia and Snake River reservoirs.'' In the same year the Bonneville Power Administration (BPA) funded ODFW and FWS to conduct collaborative studies to estimate the number of juvenile salmonids lost to predators in John Day Reservoir. Also included as study objectives were: (1) a description of the importance of predation losses relative to mortality at the dam and total reservoir mortality; (2) a description of how predationmore » losses might vary (spatially and temporally); and (3) recommendations of measures to control predation on smolts. We studied four species of predator: northern squawfish, walleye, smallmouth bass, and channel catfish. We selected John Day Reservoir as the study site because the following factors led us to believe if predation was a problem in any reservoir, it would be most obvious there because: (1) the reservoir is an important subyearling chinook rearing area; (2) passage and residualism of juvenile salmonids were considered a problem there; and (3) substantial populations of predators were known to reside in the reservoir. Individual reports were processed separately for the data base.« less

Growing up with adversity: From juvenile justice involvement to criminal persistence and psychosocial problems in young adulthood.

PubMed

Basto-Pereira, Miguel; Miranda, Ana; Ribeiro, Sofia; Maia, Ângela

2016-12-01

Several studies have been carried out to investigate the effect of child maltreatment on juvenile justice involvement and future criminal life. However, little is known about the impact of other forms of adversity, beyond abuse and neglect, on juvenile delinquency and criminal persistence. The effect of early adversity on psychosocial problems is underexplored, particularly in juvenile delinquents. This study, using the Childhood Adverse Experiences (ACE) questionnaire, a tool accessing the exposure to different types of abuse, neglect and serious household dysfunction, explored the role of each adverse experience on juvenile justice involvement, persistence in crime and psychosocial problems during young adulthood. A Portuguese sample of 75 young adults with official records of juvenile delinquency in 2010/2011, and 240 young adults from a community sample completed ACE questionnaire and measures of psychosocial adjustment. Seven out of ten adverse experiences were significantly more prevalent in young adults with juvenile justice involvement than in the community sample, after matching the main demographic variables. The strongest predictor of juvenile justice involvement and criminal persistence during early adulthood was sexual abuse. Dimensions of child/adolescent emotional maltreatment and a mental illness in the household predicted a set of psychosocial problems in young adulthood. This study indicates that early adversity is significantly related to juvenile justice involvement, criminal persistence and psychosocial problems. This study also suggests that each experience has a different role in this process. There is an urgent need to screen, prevent and stop serious adversity. Future scientific directions and recommendations for policies are provided. Copyright © 2016 Elsevier Ltd. All rights reserved.

Although arrest rates among juveniles have substantially decreased since the 1990s, US national trends in conduct problems are unknown. Population variation in conduct problems would imply changes in the social environment, which would include emergent or receding risk factors. In the present study, we separated age, period, and cohort effects on conduct problems using nationally representative surveys of 375,879 US students conducted annually (1991-2015). The summed score of 7 items measuring the frequency of conduct problems was the outcome. Conduct problems have decreased during the past 25 years among boys; the total amount of the decrease was approximately 0.4 standard deviations (P < 0.01), and by item prevalence, the total amount of the decrease was 8%-11%. Declines are best explained by period effects beginning approximately in 2008, and a declining cohort effect beginning among those born after 1992, which suggests not only declines in population levels, but more rapid declines among younger cohorts of boys. Trends were also consistent with age-period-cohort effects on evenings spent out, which suggest a possible mechanism. Conduct problems among girls were lower than boys and did not demonstrate trends across time. These changes may reflect the changing nature of adolescence toward less unsupervised interaction.

Fire interest and antisociality as risk factors in the severity and persistence of juvenile firesetting.

PubMed

MacKay, Sherri; Henderson, Joanna; Del Bove, Giannetta; Marton, Peter; Warling, Diane; Root, Carol

2006-09-01

In the DSM-IV-TR, firesetting is included as a criterion for the diagnoses of conduct disorder and pyromania. The link between firesetting and antisocial behavior is well established in the empirical literature. Although theoretical models of firesetting often include fire interest as a putative risk factor, there is little research on the role of fire interest in firesetting or on the construct of pyromania. The present study evaluated a sample of children and adolescents referred to an outpatient specialty program for juvenile firesetters with firesetting as the primary presenting problem. By assessing fire interest and antisocial behavior concurrently, the contribution of fire interest to firesetting after controlling for the role of conduct problems was evaluated. Results revealed that fire interest and antisocial behavior were significantly and positively correlated. Moreover, variations in fire interest added to the prediction of firesetting severity at assessment and firesetting recidivism at 18-month follow-up above and beyond what was predicted by antisociality alone. These findings have implications for an empirically derived taxonomy of pathological firesetting.

This study assesses the social, emotional and behavioral symptoms of 2,575 youth who were receiving behavioral health services from a private provider agency, either in an out of home placement (e.g., foster care home, a group home or a residential treatment facility) or in their own home (through the In-Home Services Program). The findings suggest the prevalence of symptoms in each of the domains (i.e., conduct problems, emotional problems, ADHD, and peer problems) were relatively high compared to the general population. Over 50% of the youth had conduct problems in the borderline or abnormal range, more than 35% had hyperactivity and peer problems subscale scores in the borderline or abnormal range, and almost 25% of the youth reported symptoms of emotional problems in the borderline or abnormal range. Youth's social, emotional and behavioral problems varied by gender, race/ethnicity and age group.

Can callous-unemotional traits enhance the understanding, diagnosis, and treatment of serious conduct problems in children and adolescents? A comprehensive review.

PubMed

Frick, Paul J; Ray, James V; Thornton, Laura C; Kahn, Rachel E

2014-01-01

This article provides a comprehensive review of the research on the use of callous and unemotional (CU) traits for designating an important subgroup of children and adolescents with severe conduct problems. It focuses on the etiological significance of recognizing this subgroup of youths with severe conduct problems, its implications for diagnostic classification, and the treatment implications of this research. The review highlights limitations in existing research and provides directions for future research. The available research suggests that children and adolescents with severe conduct problems and elevated CU traits show distinct genetic, cognitive, emotional, biological, environmental, and personality characteristics that seem to implicate different etiological factors underlying their behavior problems relative to other youths with severe conduct problems. Recognizing these subgroups could be critical for guiding future research on the causes of severe conduct problems in children and adolescents. Further, children and adolescents with both severe conduct problems and elevated CU traits appear to be at risk for more severe and persistent antisocial outcomes, even controlling for the severity of their conduct problems, the age of onset of their conduct problems, and common comorbid problems, which supports the clinical importance of designating this group in diagnostic classification systems. Finally, although children and adolescents with both severe conduct problems and elevated CU traits tend to respond less positively to typical interventions provided in mental health and juvenile justice settings, they show positive responses to certain intensive interventions tailored to their unique emotional and cognitive characteristics.

Salekin, Randall T; Lester, Whitney S; Sellers, Mary-Kate

2012-08-01

The purpose of the current study was to examine the effect of a motivational intervention on conduct problem youth with psychopathic features. Specifically, the current study examined conduct problem youths' mental set (or theory) regarding intelligence (entity vs. incremental) upon task performance. We assessed 36 juvenile offenders with psychopathic features and tested whether providing them with two different messages regarding intelligence would affect their functioning on a task related to academic performance. The study employed a MANOVA design with two motivational conditions and three outcomes including fluency, flexibility, and originality. Results showed that youth with psychopathic features who were given a message that intelligence grows over time, were more fluent and flexible than youth who were informed that intelligence is static. There were no significant differences between the groups in terms of originality. The implications of these findings are discussed including the possible benefits of interventions for adolescent offenders with conduct problems and psychopathic features.

2007-01-01

The current study sought to explore subtypes of adolescents within a sample of female juvenile offenders. Using the Millon Adolescent Clinical Inventory with 101 female juvenile offenders, a two-step cluster analysis was performed beginning with a Ward's method hierarchical cluster analysis followed by a K-Means iterative partitioning cluster analysis. The results suggest an optimal three-cluster solution, with cluster profiles leading to the following group labels: Externalizing Problems, Depressed/Interpersonally Ambivalent, and Anxious Prosocial. Analysis along the factors of age, race, offense typology and offense chronicity were conducted to further understand the nature of found clusters. Only the effect for race was significant with the Anxious Prosocial and Depressed Intepersonally Ambivalent clusters appearing disproportionately comprised of African American girls. To establish external validity, clusters were compared across scales of the Behavioral Assessment System for Children - Self Report of Personality, and corroborative distinctions between clusters were found here.

[Mental health of adolescents in the juvenile detention system: the relationship between the system's staff and external mental health services].

PubMed

Ribeiro, Débora Stephanie; Ribeiro, Fernanda Mendes Lages; Deslandes, Suely Ferreira

2018-03-12

The aim of this article is to analyze how professionals in the mental health teams of the juvenile detention system in Rio de Janeiro, Brazil, perceive the relations with the external Network of Psychosocial Care in dealing with mental health issues in adolescents serving time in juvenile detention centers. Nine interviews were held with mental health professionals in the system, and the results were presented with Fairclough's critical discourse analysis as the reference. The results were organized in three parts: the relationship between the juvenile detention system's mental health teams and the external services, difficulties experienced by the teams from the detention centers and the external network's services, and prospects and proposals. The logic of the arguments' development showed that the weakness in the agreements between administrators of the Brazilian Unified National Health System and the juvenile detention system has a daily impact on mental health activities conducted by the centers' teams. This scenario is aggravated by other structural problems such as lack of transportation and personnel to accompany adolescents on extramural appointments, and resistance on the part of professionals both inside and outside the detention centers. The study showed that both the adolescents and professionals were isolated in relation to mental health activities and policies.

2009-01-01

Background Inhalant use is among the most pernicious and poorly understood forms of adolescent substance use. Many youth in the juvenile justice system have used inhalants, but little is known about inhalant use disorders (IUDs) in antisocial youth populations. The purpose of this study was to examine the prevalence, clinical features, and latent structure of DSM-IV IUDs in a state population of antisocial youth. Methods Cross-sectional survey conducted in 2003. Of 740 youth residing in Missouri State Division of Youth Services' (MDYS) residential treatment facilities at the time the study was conducted, 723 (97.7%) completed interviews. Eighty-seven percent were male, with a mean age of 15.5 (SD = 1.2). Nearly 4 in 10 youth (38.5%; n = 279) reported lifetime inhalant use. Youth ranged from very mildly to severely antisocial. Results Of 279 inhalant users, 52 (18.6%) met DSM-IV inhalant abuse criteria and 79 (28.3%) met inhalant dependence criteria. Five of 10 IUD criteria were met by > 10% of the total sample. Latent class analyses demonstrated a substantial concordance between DSM-IV-defined IUDs and an empirically-derived classification based on responses to DSM-IV IUD diagnostic criteria. Conclusion IUDs and constituent criteria were prevalent among youth in the juvenile justice system. Two groups of problem inhalant users were identified, symptomatic users-DSM-IV inhalant abuse and highly symptomatic users-DSM-IV inhalant dependence, which differed primarily in severity of inhalant-related problems. Inhalant screening, prevention and treatment efforts in juvenile justice settings are rarely delivered, but critically needed. PMID:19267939

1999-08-01

A population-based randomized intervention trial for the prevention of conduct problems (i.e., oppositional defiant disorder and conduct disorder) is described. The LIFT (Linking the Interests of Families and Teachers) intervention was designed for all first- and fifth-grade elementary school boys and girls and their families living in at-risk neighborhoods characterized by high rates of juvenile delinquency. The 10-week intervention strategy was carefully targeted at proximal and malleable antecedents in three social domains that were identified by a developmental model of conduct problems. From 12 elementary schools, 671 first and fifth graders and their families participated either in the theory-based universal preventive intervention or in a control condition. The intervention consisted of parent training, a classroom-based social skills program, a playground behavioral program, and systematic communication between teachers and parents. A multiple measure assessment strategy was used to evaluate participant satisfaction and participation, fidelity of implementation, and the immediate impacts of the program on targeted antecedents.

Exposure to teflubenzuron negatively impacts exploratory behavior, learning and activity of juvenile European lobster (Homarus gammarus).

Infestations with salmon lice, a parasitic copepod, is a major problem in the salmon farming industry. Teflubenzuron is an in-feed pharmaceutical applied to control lice outbreaks; the standard medication is 10 mg per kg fish per day for seven days. Surveys reveal that teflubenzuron accumulates and persists in the sediment around fish farms and causes deformities and mortality in juvenile European lobster (Homarus gammarus), a species commonly found in the vicinity of salmon farms in Norway. To date, there is no information on sub-lethal effects of teflubenzuron on, for example, behavior. We conducted an experiment to assess possible difference in the shelter seeking behavior of teflubenzuron-exposed (N = 19) vs. not exposed (N = 19) H. gammarus juveniles. The teflubenzuron-exposed juveniles had been given very low concentrations, 1.7 µg per pellet twice per week for 113 days prior to this experiment. The concentration of teflubenzuron was estimated to be less than 1 ng/g lobster when they were tested in the behavior experiment. Animals were placed in a lane with a shelter at one end. Once a lobster had found and entered the shelter, they were repeatedly displaced back to the opposite end of the lane, for a total of 3 repeated runs per animal. Three of the exposed juveniles failed to settle in the shelter, and the remaining teflubenzuron-exposed animals took significantly more time to explore the environment and to find and recognize shelter. Furthermore, exposed lobsters also exhibited slower walking speed compared to the controls. These results demonstrate that teflubenzuron significantly reduces exploratory behavior, learning and activity of juvenile H. gammarus. Thus, exposure to teflubenzuron could increase predation mortality of juvenile lobsters in the wild. Copyright © 2018. Published by Elsevier Inc.

ADHD and risky sexual behavior in adolescents: Conduct problems and substance use as mediators of risk

PubMed Central

Sarver, Dustin E.; McCart, Michael R.; Sheidow, Ashli J.; Letourneau, Elizabeth J.

2015-01-01

Background Recent studies have linked attention-deficit/hyperactivity disorder (ADHD) to elevated rates of risky sexual behavior (RSB) in adult samples. The current study tested whether ADHD symptoms were associated with RSB among adolescents, and examined comorbid conduct problems and problematic substance use as joint mediators of this association. Methods ADHD symptoms, conduct problems (oppositional defiant disorder/conduct disorder symptoms), problematic alcohol use (alcohol use disorder symptoms, alcohol use frequency), problematic marijuana use (marijuana use disorder symptoms, marijuana use frequency), and RSB were assessed among an ethnically diverse cross-sectional sample of adolescents (N=115; mean age=14.9 years) involved in the juvenile justice system. Results Bootstrapped mediation models revealed an initial association between ADHD symptoms and RSB that was accounted for fully by the influence of problematic alcohol and marijuana use, but not conduct problems. A follow-up multiple groups mediation analysis demonstrated that the relationship between ADHD symptoms and RSB emerged only among youth with clinically elevated conduct problems, and that problematic marijuana use fully accounted for this relationship. Hyperactive/impulsive but not inattentive symptoms were related to RSB, although the pattern of indirect effects was consistent with the multiple groups analysis. Conclusions The association between ADHD and adolescent RSB is restricted to youth with elevated comorbid conduct problems and reflects the contributions of comorbid marijuana use problems, and to a lesser extent alcohol use problems. Early identification and treatment of these comorbid conditions may be important for the prevention of negative sexual health outcomes among youth with ADHD. PMID:24813803

2012-02-01

Research to establish an evidence-base for the treatment of conduct problems and delinquency in adolescence is well established; however, an evidence-base for interventions with offenders who are diverted from the juvenile justice system has yet to be synthesized. The purpose of this study was to conduct a meta-analysis of experimental studies testing juvenile diversion programs and to examine the moderating effect of program type and implementation quality. A literature search using PsycINFO, Web of Science, and the National Criminal Justice Reference Service data-bases and research institute websites yielded 28 eligible studies involving 57 experimental comparisons and 19,301 youths. Recidivism was the most common outcome reported across all studies. Overall, the effect of diversion programs on recidivism was non-significant (k=45, OR=0.83, 95%CI=0.43-1.58). Of the five program types identified, including case management (k=18, OR=0.78), individual treatment (k=11, OR=0.83), family treatment (k=4, OR=0.57), youth court (k=6, OR=0.93), and restorative justice (k=6, OR=0.87), only family treatment led to a statistically significant reduction in recidivism. Restorative justice studies that were implemented with active involvement of researchers led to statistically significant reductions in recidivism (k=3, OR=0.69). Other outcomes, including frequency of offending, truancy, and psycho-social problems were reported infrequently and were not subjected to meta-analysis. High levels of heterogeneity characterize diversion research. Results of this study recommend against implementation of programs limited to case management and highlight the promise of family interventions and restorative justice. Copyright © 2011 Elsevier Ltd.

Corneau, Mélanie; Lanctôt, Nadine

2004-01-01

Empirical evidence indicates that the rates of mental health problems and disorders are relatively high among adjudicated youths, especially females, yet few longitudinal studies have focused on gender differences regarding their mental health outcomes as adults. The present study was designed to assess the prevalence rates of self-reported suicide attempts and psychological help-seeking in young adults adjudicated for antisocial behaviours in adolescence. This study also assessed gender differences in the prevalence rates of mental health problems and disorders reported by participants. Structured interviews assessing personal and social adaptation were conducted on three occasions with 292 adjudicated male and 113 female youths (mean age 15 years on the first occasion). Data from the third testing wave (mean age 23.51 at T3) provide information on their mental health outcomes in adulthood. Results indicate that in individuals with a history of juvenile delinquency and/or problem behaviour over 10% of the males and 20% of the females reported suicide attempts, and one-fifth and one-third respectively reported psychological consultation. Similar and lower proportions reported psychiatric hospitalization and/or drug addiction programme/therapy at the beginning of adulthood. The present study suggests that these youths may need more mental health directed interventions in their assessment rehabilitation programmes.

Manders, Willeke A; Deković, Maja; Asscher, Jessica J; van der Laan, Peter H; Prins, Pier J M

2013-10-01

The aim of the present study was to determine whether psychopathic traits act as a predictor and/or moderator of the effectiveness of Multisystemic Therapy (MST). The sample included N = 256 adolescents (188 boys and 68 girls) referred for conduct problems, randomized to MST or Treatment As Usual (TAU). The mean age was 16 years (SD = 1.31). Assessments were carried out before and immediately after treatment (6 months later). Three psychopathic traits (callous/unemotional traits, narcissism, and impulsiveness) were assessed with parent reports. Adolescents and parents were informants on externalizing problems. MST was more effective than TAU in decreasing externalizing problems for the "lower callous/unemotional" and "lower narcissism" group, but not for the "high callous/unemotional" and "high narcissism" group (moderators). Impulsiveness was found to predict more post-treatment externalizing problems rated by adolescents (predictor), but not more post-treatment externalizing problems rated by parents. These findings point out the clinical relevance of adequately assessing psychopathic traits in adolescents referred for treatment of antisocial behaviour, and identifying those adolescents who show high levels of these traits. It is important to tailor MST specifically to meet the needs of juveniles with high levels of callous/unemotional traits and high levels of narcissism to obtain the same level of effectiveness as with juveniles scoring lower on these traits.

Trauma, Delinquency, and Substance Use: Co-occurring Problems for Adolescent Girls in the Juvenile Justice System.

PubMed

Smith, Dana K; Saldana, Lisa

2013-07-02

Girls in the juvenile justice system are known to have high rates of co-occurring childhood abuse, trauma, and substance abuse. Girls with this constellation of problems are at high risk for serious adverse outcomes, including problems with drug dependence and abuse. The relationship between childhood sexual abuse, childhood physical abuse, other types of childhood trauma, and rates of substance use during adolescence were examined for girls in the juvenile justice system. As expected, childhood sexual abuse was significantly related to girls' substance use during adolescence. In contrast to prior research, no link was found between physical abuse, lifetime trauma, and substance use. Limitations and future directions are discussed.

2016-01-01

This study examined the influence of treatment motivation on posttreatment effectiveness of an outpatient, individual social skills training for juvenile delinquents imposed as a penal sanction. Propensity score matching was used to match a control group of juveniles receiving treatment as usual (n = 108 of total N = 354) to a treatment group of juveniles receiving Tools4U, a social skills training with a parental component (N = 115). Treatment motivation was examined as a moderator and predictor of treatment effects on impulsivity, social perspective-taking, social problem-solving, lack of critical reasoning, developmental task-related skills, and parenting skills. Treatment effects were mostly consistent across juveniles with different levels of treatment motivation. Only one moderating effect was found on active tackling (i.e., actively addressing problems), and predictive effects were found on seeking social support, cognitive empathy, hostile intent attribution, and self-centeredness. Implications for further research are discussed. PMID:27225504

Talking with juvenile offenders about gay males and lesbians: implications for combating homophobia.

PubMed

Van de Ven, P

1995-01-01

Violence against gay males and lesbians, much of it perpetrated by young people, has emerged as a significant social problem. Thirty-one juvenile offenders were asked a series of structured questions in order to elucidate the functions their attitudes toward homosexuals serve. In addition, responses were examined for evidence of social-structural and cognitive variables which mediate offending behaviors. Juvenile offenders were found to hold attitudes toward homosexuals characterized by negativity, ambivalence, and defensiveness. These attitudes were maintained by particular myths and stereotypes about gay and lesbian culture, and were related to Opportunism, Impulsivity, Role-Taking Inability, and Disabilities in Social Problem Solving. Specific recommendations for combating homophobic attitudes and behaviors in juvenile offender populations are discussed.

Assessing the criminal capacity of children: a challenge to the capacity of mental health professionals.

PubMed

Pillay, Anthony L; Willows, Clive

2015-01-01

With increasing numbers of juveniles accused of serious crimes international concern is growing around the procedural consequences for affected individuals within the context of the law and criminal justice. Issues of culpability in children and adolescents are often raised, with much deliberation and insufficient agreement among legal and child development experts. Exactly when and to what extent juveniles can be held responsible for their action is a matter requiring careful consideration to avoid substantial erring in either direction. Although some international guiding standards and principles have been established, these are rather broad and unable to provide specific prescriptions. In addition, the assessment of criminal capacity in juveniles is a complex task, and one that is not wholly without reliability and validity problems. As in the case of South Africa and a few other countries, mental health specialists are often tasked with conducting developmental assessments to provide courts with expert evidence regarding criminal capacity. This paper examines the concept of criminal capacity in the context of the theory, controversies and challenges that affect this area of psychological focus.

ADHD and risky sexual behavior in adolescents: conduct problems and substance use as mediators of risk.

PubMed

Sarver, Dustin E; McCart, Michael R; Sheidow, Ashli J; Letourneau, Elizabeth J

2014-12-01

Recent studies have linked attention-deficit/hyperactivity disorder (ADHD) to elevated rates of risky sexual behavior (RSB) in adult samples. The current study tested whether ADHD symptoms were associated with RSB among adolescents, and examined comorbid conduct problems and problematic substance use as joint mediators of this association. ADHD symptoms, conduct problems (oppositional defiant disorder/conduct disorder symptoms), problematic alcohol use (alcohol use disorder symptoms, alcohol use frequency), problematic marijuana use (marijuana use disorder symptoms, marijuana use frequency), and RSB were assessed among an ethnically diverse cross-sectional sample of adolescents (N = 115; mean age = 14.9 years) involved in the juvenile justice system. Bootstrapped mediation models revealed an initial association between ADHD symptoms and RSB that was accounted for fully by the influence of problematic alcohol and marijuana use, but not conduct problems. A follow-up multiple groups mediation analysis demonstrated that the relationship between ADHD symptoms and RSB emerged only among youth with clinically elevated conduct problems, and that problematic marijuana use fully accounted for this relationship. Hyperactive/impulsive, but not inattentive, symptoms were related to RSB, although the pattern of indirect effects was consistent with the multiple groups analysis. The association between ADHD and adolescent RSB is restricted to youth with elevated comorbid conduct problems and reflects the contributions of comorbid marijuana use problems, and to a lesser extent alcohol use problems. Early identification and treatment of these comorbid conditions may be important for the prevention of negative sexual health outcomes among youth with ADHD. © 2014 The Authors.

The Washington Department of Fish & Wildlife (WDFW) assumed responsibility for the Smolt Monitoring Program at McNary Dam on the Columbia River in 1990 and at the new juvenile collection facility at Lower Monumental Dam on the Snake River in 1993. In 1996, Smolt Monitoring Program activities also began at the new juvenile collection facility located at Ice Harbor Dam. This report summarizes the 1996 Smolt Monitoring work at all three sites. The work at Ice Harbor consisted of Gas Bubble Trauma (GBT) monitoring only. In general, the 1996 passage season at both the McNary and Lower Monumental sites canmore » be characterized by reduced passage of juveniles through the collection systems due to elevated river flows and spill, and low (<1%) overall facility mortality rates most likely resulting from cooler water temperatures. In accordance with the National Marine Fisheries Service recommendations (NMFS, 1995) all spring migrants were bypassed at McNary Dam in 1996. Mechanical problems within the McNary collection system resulted in collection and sampling activities being delayed until April 18 at this site, while sampling and collection began on the scheduled starting date of April 1 at Lower Monumental Dam. Monitoring operations were conducted through December 14 at McNary Dam and through October 28 at Lower Monumental Dam. An ongoing transportation evaluation summer migrant marking program was conducted at McNary Dam in 1996 by the NMFS. This necessitated the sampling of 394,211 additional fish beyond the recommended sampling guidelines. All total, 509,237 and 31,219 juvenile salmonids were anesthetized and individually counted, examined for scale loss, injuries, and brands by WDFW Smolt Monitoring personnel in 1996 at McNary Dam and Lower Monumental Dam, respectively.« less

Mental Health Referrals Reduce Recidivism in First-Time Juvenile Offenders, But How Do We Determine Who is Referred?

PubMed

Zeola, Michael P; Guina, Jeffrey; Nahhas, Ramzi W

2017-03-01

While psychiatric disorders are common among juvenile delinquents, many mental health problems go undetected, increasing the likelihood for persistent difficulties. This is the first known study to examine mental health referral rates and recidivism in the juvenile justice system. In addition to the study, we review juvenile justice mental health screening to improve detection and treatment. Juvenile criminal records in conjunction with behavioral health screenings were analyzed to determine differences in referrals and recidivism among first time offenders. Recidivism rates were significantly lower (p = 0.04) and time to recidivism was significantly longer (p = 0.03) for those referred specifically for mental health services than for those without any referrals, even after adjusting for offense severity. While black youths had a significantly higher recidivism rate (p = 0.02) and a shorter time to recidivism (p = 0.009) than white youths, there was no significant difference between races when referred specifically for mental health services. Among the groups studied, black youths had the most profound positive effect from mental health referrals (p < 0.0001). This study indicates the importance of detecting mental health problems among juvenile delinquents, especially for black offenders. The apparent protective effect of mental health interventions necessitates screening that better identifies underlying psychosocial factors rather than strict reliance upon diagnostic criteria and self-report. Broader or even universal mental health referrals for juvenile offenders could reduce future legal system involvement and costs to society. We review potential reasons that mental health problems go undetected and provide recommendations.

Enhancement of juvenile Caribbean spiny lobsters: an evaluation of changes in multiple response variables with the addition of large artificial shelters.

PubMed

Briones-Fourzán, Patricia; Lozano-Alvarez, Enrique; Negrete-Soto, Fernando; Barradas-Ortiz, Cecilia

2007-03-01

Shortage of natural crevice shelters may produce population bottlenecks in juvenile Caribbean spiny lobsters (Panulirus argus), a socially gregarious species. We conducted a field experiment to test enhancement of a local population of juvenile P. argus with the addition of artificial shelters ("casitas") that mimic large crevices (1.1 m(2) in surface area and 3.8 cm in height). Changes in density and biomass of juvenile lobsters 15-50 mm carapace length (CL) were assessed with a multiple before-after control-impact (MBACI) analysis. Separate analyses were also conducted on small (15-35 mm CL) and large (35.1-50 mm CL) juveniles to assess size-related effects. First, we carried out 13 lobster surveys on nine fixed 1-ha sites over a shallow reef lagoon ("before" period). Then, we deployed ten casitas in each of five sites and left four sites as controls, and conducted 22 further surveys ("after" period). Deployment of casitas resulted in a sixfold increase in juvenile density (76% contributed by small and 24% by large juveniles) and a sevenfold increase in biomass (40 and 60%, respectively). Capture-recapture results revealed that enhancement was achieved not by promoting individual growth but by increasing survival, persistence, and foraging ranges of small and large juveniles. Casitas both mitigated shortage of natural shelter and increased sociality, allowing for cohabitation of smaller, more vulnerable juveniles with larger conspecifics that have greater defensive abilities. Casitas may help enhance local populations of juvenile P. argus in Caribbean seagrass habitats, typically poor in natural crevice shelters. The use of MBACI and the simultaneous assessment of multiple interrelated response variables may be a powerful analytical approach to test shelter limitation in other species and to examine the function of structural habitat in other systems.

Examining ethnic differences in self-reported psychopathic traits among Portuguese male juvenile offenders.

Pechorro, Pedro; Poiares, Carlos; Barroso, Ricardo; Nunes, Cristina; Jesus, Saul Neves

2015-01-01

The aim of the present study was to analyze differences regarding psychopathic traits and related constructs in male youths of diverse ethnic backgrounds. The participants were 216 male youths from the Juvenile Detention Centers of the Portuguese Ministry of Justice (White Europeans group: n = 108; ethnic minorities group: n = 108). Psychopathy was measured by the Antisocial Process Screening Device and the Child and Adolescent Taxon Scale. The results showed that no differences were found between ethnic groups regarding psychopathic traits and psychopathy taxon. Independent of ethnic group membership, psychopathic trait scores were significantly associated with behavioral problems, conduct disorder, self-reported delinquency, seriousness of criminal activity, age of criminal activity onset, and age at first trouble with the law. The present study adds support to the literature regarding youth psychopathic traits and supports the psychopathy construct as universally and interculturally consistent. © The Author(s) 2013.

Non-surgical treatment of hallux valgus: a current practice survey of Australian podiatrists.

PubMed

Hurn, Sheree E; Vicenzino, Bill T; Smith, Michelle D

2016-01-01

Patients with hallux valgus (HV) frequently present to podiatrists for non-surgical management, with a wide range of concerns including pain, footwear difficulty and quality of life impacts. There is little research evidence guiding podiatrists' clinical decisions surrounding non-surgical management of HV. Thus practitioners rely largely upon clinical experience and expert opinion. This survey was conducted to determine whether a consensus exists among Australian podiatrists regarding non-surgical treatment of HV, and secondly to explore common presenting concerns and physical examination findings associated with HV. An online survey was distributed to Australian podiatrists in mid-2013 via the professional association in each state (approximately 1900 members). Podiatrists indicated common treatments recommended, presenting problems and physical examination findings associated with HV in juveniles, adults and older adults. Proportions were calculated to determine the most common responses, and Chi-squared tests were used to examine differences in treatment recommendations according to HV patient age group and podiatrist demographics. Of 210 survey respondents, 65 % (136) were female and 80 % (168) were private practitioners. Complete survey responses were received from 159 podiatrists for juvenile HV, 146 for adults and 141 for older adults. Seven different non-surgical treatment options were commonly recommended (by >50 % podiatrists), although recommendations differed between adult, older adult and juvenile HV. Common treatments included footwear advice or modification, custom and prefabricated orthotic devices, addition of padding, and muscle strengthening/retraining exercises. Padding was more likely to be utilised in older adults, while exercises were more likely to be prescribed for juveniles. A diverse range of presenting problems and physical examination findings were reported to be associated with HV. Despite the lack of empirical evidence in this area, there appears to be a consensus among Australian podiatrists regarding non-surgical management of HV, and these recommendations are largely aligned with available clinical consensus documents. Presenting concerns and physical examination findings associated with HV are diverse and have implications for treatment decisions. Management strategies differ across patient age groups, thus any updated clinical guidelines should differentiate between adult and juvenile HV. This study provides useful data to inform clinical practice, education, policy and future research.

Mediation of the relationship between callous-unemotional traits and proactive aggression by amygdala response to fear among children with conduct problems.

2014-06-01

Among youths with conduct problems, callous-unemotional (CU) traits are known to be an important determinant of symptom severity, prognosis, and treatment responsiveness. But positive correlations between conduct problems and CU traits result in suppressor effects that may mask important neurobiological distinctions among subgroups of children with conduct problems. To assess the unique neurobiological covariates of CU traits and externalizing behaviors in youths with conduct problems and determine whether neural dysfunction linked to CU traits mediates the link between callousness and proactive aggression. This cross-sectional case-control study involved behavioral testing and neuroimaging that were conducted at a university research institution. Neuroimaging was conducted using a 3-T Siemens magnetic resonance imaging scanner. It included 46 community-recruited male and female juveniles aged 10 to 17 years, including 16 healthy control participants and 30 youths with conduct problems with both low and high levels of CU traits. Blood oxygenation level-dependent signal as measured via functional magnetic resonance imaging during an implicit face-emotion processing task and analyzed using whole-brain and region of interest-based analysis of variance and multiple-regression analyses. Analysis of variance revealed no group differences in the amygdala. By contrast, consistent with the existence of suppressor effects, multiple-regression analysis found amygdala responses to fearful expressions to be negatively associated with CU traits (x = 26, y = 0, z = -12; k = 1) and positively associated with externalizing behavior (x = 24, y = 0, z = -14; k = 8) when both variables were modeled simultaneously. Reduced amygdala responses mediated the relationship between CU traits and proactive aggression. The results linked proactive aggression in youths with CU traits to hypoactive amygdala responses to emotional distress cues, consistent with theories that externalizing behaviors, particularly proactive aggression, in youths with these traits stem from deficient empathic responses to distress. Amygdala hypoactivity may represent an intermediate phenotype, offering new insights into effective treatment strategies for conduct problems.

Young offenders are known to be a population with high prevalence of mental health disorders. In most cases, these disorders are neither identified nor treated properly, with the majority of them being chronic and difficult to treat. In many countries, the prevalence rates of psychopathology in male young offenders are still unknown and no psychotherapeutic interventions are delivered. Therefore, the main goal of the present study was to assess mental health problems in Portuguese male young offenders placed in either custodial or community-based programs and discuss treatment implications within the juvenile justice interventions. Participants in this study included 217 male young offenders aged between 14 and 20 years old that were randomly selected using a random number table. From the total sample, 122 (56.3 %) participants were placed in juvenile detention facilities, and 95 (43.7 %) were receiving community-based programs. Participants were interviewed with the Mini-International Neuropsychiatric Interview for Children and Adolescents, a structured interview that assesses DSM-IV Axis I Mental Disorders. Participants aged 18 years or older were also assessed with the antisocial personality disorder section from the Structured Clinical Interview for DSM-IV Axis II Personality Disorders. Results showed a high prevalence of mental health disorders, with a global prevalence of 91.2 % in the total sample. In both groups, global prevalence rates were equally high (93.4 % in youth in custodial versus 88.4 % in youth in community-based programs). Substance-related disorders were more prevalent in youth placed in juvenile facilities, whereas anxiety and mood disorders were more often found in the community-based group. Moreover, oppositional defiant disorder was more prevalent in youth from the community, whereas antisocial personality disorder and conduct disorder were less prevalent than expected in this same group. A high comorbidity rate was also found, with the majority of participants from both groups' fulfilling criteria for two or more disorders. Additionally, participants with conduct disorder were over four times more likely to fulfill criteria for substance abuse. Our findings inform about specific needs concerning mental health intervention that should be taken into account when deciding and planning rehabilitation programs for male young offenders, either from custodial or community-based programs.

Can you teach an old parrot new tricks? Cognitive development in wild kaka (Nestor meridionalis)

PubMed Central

Shaw, Rachael C.; Burns, Kevin C.

2016-01-01

Despite recent efforts to characterize innovative individuals within a species, we still know very little about the ontogeny of innovation ability. A number of studies have found that innovation rates are correlated with personality traits, such as neophilia and exploration. Juvenile birds are frequently more neophilic and explorative, yet few studies have found evidence of age-related differences in innovative problem-solving success. Here, we show consistently higher innovation efficiency in juveniles of a wild, omnivorous parrot species across a variety of tasks and contexts. We tested 104 kaka (Nestor meridionalis), ranging in age from four months to 13 years. Twenty-four individuals participated in all three of our problem-solving tasks, two of which involved a familiar feeder and one an entirely novel apparatus. Juveniles were the most efficient problem-solvers in all three tasks. By contrast, the adults’ success was context dependent and limited to the novel apparatus, which did not require modification of a pre-learned behavioural response. This suggests greater behavioural flexibility in the juvenile birds, who also showed higher persistence and exploratory diversity than adults. These traits may enable young kaka to discover efficient foraging techniques, which are then maintained throughout adulthood. PMID:27252018

The link between substance use and involvement in the juvenile justice system has been well established. Justice-involved youth tend to have higher rates of drug use than their non-offending peers. At the same time, continued use can contribute to an elevated risk of recidivism, which leads to further, and oftentimes more serious, involvement with the juvenile justice system. Because of these high rates of use, the juvenile justice system is well positioned to help identify youth with substance use problems and connect them to treatment. However, research has found that only about 60% of juvenile probation agencies screen all youth for substance involvement, and even fewer provide comprehensive assessment or help youth enroll in substance use treatment. This paper describes an integrated training curriculum that was developed to help juvenile justice agencies improve their continuum of care for youth probationers with substance use problems. Goal Achievement Training (GAT) provides a platform for continuous quality improvement via two sessions delivered onsite to small groups of staff from juvenile justice and behavioral health agencies. In the first session, participants are taught to identify goals and goal steps for addressing identified areas of unmet need (i.e., screening, assessment, and linkage to treatment services). In the second session, participants learn principles and strategies of data-driven decision-making for achieving these goals. This paper highlights GAT as a model for the effective implementation of cost-efficient training strategies designed to increase self-directed quality improvement activities that can be applied to any performance domain within juvenile justice settings. Efforts to monitor implementation fidelity of GAT within the specific context of the juvenile justice settings are highlighted. Challenges to setting the stage for process improvement generally, as well as specific hurdles within juvenile justice settings are discussed, as are next steps in disseminating findings regarding the fidelity to and effectiveness of GAT in this unique context.

A comparative test of the investigator as a variable in aging quail

Rosene, W.; Fitch, F.

1956-01-01

To test the reliability of current techniques, five biologists appraised the ages of 200 quail from a random sample of wings collected during the 1952-53 hunting season in Alabama. Attempt was made to distinguish adults from juveniles, to ascertain the stage of post-nuptial and post-juvenile molts, and to estimate the age of juveniles according to days or weeks. Three 'problem' wings in this sample had molt characteristics somewhat eauallv divided between adult and juvenile classes; two wings called 'questionable' had all molt characteristics except one of either age group. A 3.5 per cent disparity occurred between investigators in their classification of adult and juvenile age groups. This included not only 'problem' and 'questionable' wings, but also 'obvious errors.' Individual differences were greater than 3.5 per cent but cancelled out. This study emphasizes the need of working with large samples of birds of a known age in order to know more concerning molt variations. Until aging techniques can be refined, it is believed that investigators should be fully familiar with existing methods and their weaknesses. Also, it appears important that reports on aging should indicate clearly the techniques used.

Longitudinal studies found that criminal behavior in juveniles often concurs with neighborhood disadvantage and family dysfunction, especially in girls. In this study we assessed the psychosocial background in incarcerated juveniles and analyzed the data for each gender separately. The Multidimensional Clinical Screening Inventory for delinquent juveniles (MCSI) was used to assess school history, psychiatric history, family background, abuse and neglect and motive for crime. The sample consisted of 294 juveniles (46 females and 248 males). Innerfamilial abuse/neglect was reported by 91% (girls) and 79% (boys). 76% (girls) and 88% (boys) reported school-problems. 57% (girls) and 29% (boys) reported to have recieved psychiatric pretreatment. In girls we found significantly higher prevalence rates for parental divorce, incarceration of mother, abuse/neglect and psychiatric pretreatment. Significantly more girls reported a co-occurrence of school-problems and experiences of separation and loss and abuse (65.2% vs. 46.4%, χ²=5.51, df=1, p<.05). Incarcerated juveniles, especially females, are and have been exposed to multiple psychosocial burdens. Therefore it is necessary to implement prevention programs for psychosocially stressed families. Forensic intervention in and after detention has to include a family centered approach.

We investigated effects of severe hypoxia (dissolved oxygen <1 ml l(-1)) on recruitment of mantis shrimp Oratosquilla oratoria in Tokyo Bay. Ten-year field surveys were conducted to examine quantitative relationships in annual mean densities of larvae and juveniles, and spatial distribution of juveniles and severe hypoxia. There was no significant correlation between annual mean densities of larvae and juveniles, suggesting that mortality during larval or juvenile stages varies among years, which might have regulated abundance of young-of-the-year juveniles. Juvenile density was low in the severely hypoxic area, implying that hypoxia could affect survivals and spatial distribution of juveniles. Meanwhile, there are yearly fluctuations in juvenile density in normoxic areas of both northern and southern part of the bay. This evidence suggests that abundance of post-settled juveniles might have been determined by not only effects of hypoxia, but also other factors influencing mortality during the early life stages.

The present study evaluated the performance and variability in acute toxicity tests with glochidia and newly transformed juvenile mussels using the standard methods outlined in American Society for Testing and Materials (ASTM). Multiple 48-h toxicity tests with glochidia and 96-h tests with juvenile mussels were conducted within a single laboratory and among five laboratories. All tests met the test acceptability requirements (e.g., ???90% control survival). Intralaboratory tests were conducted over two consecutive mussel-spawning seasons with mucket (Actinonaias ligamentina) or fatmucket (Lampsilis siliquoidea) using copper, ammonia, or chlorine as a toxicant. For the glochidia of both species, the variability of intralaboratory median effective concentrations (EC50s) for the three toxicants, expressed as the coefficient of variation (CV), ranged from 14 to 27% in 24-h exposures and from 13 to 36% in 48-h exposures. The intralaboratory CV of copper EC50s for juvenile fatmucket was 24% in 48-h exposures and 13% in 96-h exposures. Interlaboratory tests were conducted with fatmucket glochidia and juveniles by five laboratories using copper as a toxicant. The interlaboratory CV of copper EC50s for glochidia was 13% in 24-h exposures and 24% in 48-h exposures, and the interlaboratory CV for juveniles was 22% in 48-h exposures and 42% in 96-h exposures. The high completion success and the overall low variability in test results indicate that the test methods have acceptable precision and can be performed routinely. ?? 2007 SETAC.

Juvenile Radio-Tag Study: Lower Granite Dam, 1985 Annual Report.

DOE Office of Scientific and Technical Information (OSTI.GOV)

Stuehrenberg, Lowell C.

The concept of using mass releases of juvenile radio tags represents a new and potentially powerful research tool that could be effectively applied to juvenile salmonid passage problems at dams on the Columbia and Snake Rivers. A system of detector antennas, strategically located, would automatically detect and record individually tagged juvenile salmonids as they pass through the spillway, powerhouse, bypass system, or tailrace areas below the dam. Accurate measurements of spill effectiveness, fish guiding efficiency (FGE), collection efficiency (CE), spillway survival, powerhouse survival, and bypass survival would be possible without handling large numbers of unmarked fish. A prototype juvenile radio-tagmore » system was developed and tested by the National Marine Fisheries Service (NMFS) and Bonneville Power Administration (BPA) at John Day Dam and at Lower Granite Dam. This report summarizes research to: (1) evaluate the effectiveness of the prototype juvenile radio-tag system in a field situation and (2) to test the basic assumptions inherent in using the juvenile radio tag as a research tool.« less

2015-11-01

Nearly half a million inmates with mental health issues are housed in our country’s jails and prisons. The majority of juvenile justice-involved (JJI) youth have a history of behavioral health (mental health or substance use) problems. Multiple studies estimate that between 65% to 75% of juvenile justice-involved youth have at least one behavioral health disorder, and 20% to 30% report suffering from a serious behavioral disorder. With so many juveniles with behavioral health issues entering a system that was not designed to provide comprehensive treatment, communities are reevaluating their approach to juvenile justice. This article describes the origins and the results of Ohio’s Behavioral Health Juvenile Justice Initiative (BHJJ), a diversion program for juvenile justice-involved youth with behavioral health issues. The authors also discuss the key components of program success, offer advice to other jurisdictions considering implementing similar programming, and identify ways to take diversion programs to scale.

2016-01-01

Research on juvenile justice aims to identify profiles of risk and protective factors in juvenile offenders. This paper presents a study of profiles of risk factors that influence young offenders toward committing sanctionable antisocial behavior (S-ASB). Decision tree analysis is used as a multivariate approach to the phenomenon of repeated sanctionable antisocial behavior in juvenile offenders in Spain. The study sample was made up of the set of juveniles who were charged in a court case in the Juvenile Court of Almeria (Spain). The period of study of recidivism was two years from the baseline. The object of study is presented, through the implementation of a decision tree. Two profiles of risk and protective factors are found. Risk factors associated with higher rates of recidivism are antisocial peers, age at baseline S-ASB, problems in school and criminality in family members. PMID:27611313

2010-02-01

Two studies were conducted to identify the incidence (Study 1) and characteristics (Study 2) of juvenile prostitution cases known to law enforcement agencies in the United States. Study 1 revealed a national estimate of 1,450 arrests or detentions (95% confidence interval [CI]: 1,287-1,614) in cases involving juvenile prostitution during a 1-year period. In Study 2, exploratory data were collected from a subsample of 138 cases from police records in 2005. The cases are broadly categorized into three main types: (a) third-party exploiters, (b) solo prostitution, and (c) conventional child sexual abuse (CSA) with payment. Cases were classified into three initial categories based on police orientation toward the juvenile: (a) juveniles as victims (53%), (b) juveniles as delinquents (31%), and (c) juvenile as both victims and delinquents (16%). When examining the status of the juveniles by case type, the authors found that all the juveniles in CSA with payment cases were treated as victims, 66% in third-party exploiters cases, and 11% in solo cases. Findings indicate law enforcement responses to juvenile prostitution are influential in determining whether such youth are viewed as victims of commercial sexual exploitation or as delinquents.

Mediation of the Relationship Between Callous-Unemotional Traits and Proactive Aggression by Amygdala Response to Fear Among Children With Conduct Problems

Lozier, Leah M.; Cardinale, Elise M.; VanMeter, John W.; Marsh, Abigail A.

2015-01-01

Importance Among youths with conduct problems, callous-unemotional (CU) traits are known to be an important determinant of symptom severity, prognosis, and treatment responsiveness. But positive correlations between conduct problems and CU traits result in suppressor effects that may mask important neurobiological distinctions among subgroups of children with conduct problems. Objective To assess the unique neurobiological covariates of CU traits and externalizing behaviors in youths with conduct problems and determine whether neural dysfunction linked to CU traits mediates the link between callousness and proactive aggression. Design, Setting, and Participants This cross-sectional case-control study involved behavioral testing and neuroimaging that were conducted at a university research institution. Neuroimaging was conducted using a 3-T Siemens magnetic resonance imaging scanner. It included 46 community-recruited male and female juveniles aged 10 to 17 years, including 16 healthy control participants and 30 youths with conduct problems with both low and high levels of CU traits. Main Outcomes and Measures Blood oxygenation level–dependent signal as measured via functional magnetic resonance imaging during an implicit face-emotion processing task and analyzed using whole-brain and region of interest–based analysis of variance and multiple-regression analyses. Results Analysis of variance revealed no group differences in the amygdala. By contrast, consistent with the existence of suppressor effects, multiple-regression analysis found amygdala responses to fearful expressions to be negatively associated with CU traits (x = 26, y = 0, z = −12; k = 1) and positively associated with externalizing behavior (x = 24, y = 0, z = −14; k = 8) when both variables were modeled simultaneously. Reduced amygdala responses mediated the relationship between CU traits and proactive aggression. Conclusions and Relevance The results linked proactive aggression in youths with CU traits to hypoactive amygdala responses to emotional distress cues, consistent with theories that externalizing behaviors, particularly proactive aggression, in youths with these traits stem from deficient empathic responses to distress. Amygdala hypoactivity may represent an intermediate phenotype, offering new insights into effective treatment strategies for conduct problems. PMID:24671141

Nonsuicidal self-injury (NSSI) is a frequent phenomenon in adolescents, however there is a lack of studies on the prevalence of NSSI in adolescents placed in youth welfare and juvenile justice group homes. The goal of the present study is to investigate the prevalence rates of NSSI and mental disorders in adolescents living in the youth welfare system, as well as how occasional and repetitive NSSI differ with respect to mental disorders, suicidality, and gender. The sample consisted of 397 adolescents aged 12 to19 years (mean age = 15.98, SD = 1.77, 65.7% male) placed in youth welfare and juvenile justice group homes. NSSI, suicidality, and mental disorders were assessed using the Kiddie-Schedule of Affective Disorders and Schizophrenia (K-SADS-PL). Lifetime prevalence rates of occasional and repetitive NSSI were 21.9% and 18.4%, respectively and 85.6% of the sample endorsed a lifetime mental disorder. Occasional and repetitive NSSI were significantly associated with depressive, conduct, and substance use disorders (d = 0.50-0.67) among both genders. Prevalence rates of repetitive NSSI in youth welfare and juvenile justice institutions are higher than in the general population and males who engage in NSSI are at particularly high risk of suicidality. Due to the high prevalence of NSSI and its related problems, NSSI should be routinely assessed in this vulnerable population and staff should be trained in recognizing and handling NSSI as well as supporting adolescents in improving their emotion regulation skills.

As from 2008, juveniles sentenced under civil law and juveniles sentenced under criminal law can no longer be assigned to the same juvenile detention centres. The reasoning runs as follows: the centres are unlikely to provide adequate treatment for the 'civil' group, and the 'criminal' group may exert a negative influence on the 'civil' group. Hitherto, there has been no research into the question of whether the problems and treatment requirements of girls in the two categories call for detention in the same detention centres or in different ones. The aim of this study is to investigate differences between the two groups of girls with regard to offence history, sociodemographic characteristics, contact with the social services, psychiatric disorders and trauma. Investigation of a representative sample of 211 female minors in three juvenile detention centres using standard instruments. results 82% of the girls were detained under civil law, 18% under criminal law. There were strong similarities between the groups. However, the 'criminal' group more often had a violent history of delinquency and a non-Dutch background, whereas the 'civil' group more often had a background of residential placements, oppositional-defiant disorder, suicidality and self-harm. Girls detained under civil and under criminal law differed in characteristics such as criminal record, but there were striking similarities in the girls' behavioural problems and psychiatric disorders. It is argued that assignment to a particular type of detention centre should depend on treatment requirements rather than on measures imposed by civil or criminal law.

In recent years, there has been an increasing interest in juvenile sex offenders showing that this population is highly heterogeneous. The aim of the present study was to identify possible different profiles that could help understand the motivation behind offending, comparing 31 Juvenile Sexual Offenders (JSOs), 31 Juvenile Sexual Non Offenders (JSNOs) and 31 Juvenile Non Offenders (Control Group). A data collection form, the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) or Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the Coping Inventory for Stressful Situations (CISS) and the Parental Bonding Inventory (PBI) were administered to all participants. The results show that JSOs differs from JNSOs in some domains, such as living in single-parent homes, while maintain some common aspects such as academic failure and previous sexual intercourse. Moreover, JNSOs showed more abnormal personality traits, such as Authority Problems, MacAndrew Alcoholism, Acknowledgement and Alcohol-Drug Problem Proneness compared to JSOs and the Control Group, while JSOs and JNSOs use a coping strategy more oriented to Avoidance and Distraction compared to the Control group. Finally, JSOs described the relationships with fathers characterized by higher care and protection than JNSOs. These findings provide additional evidence with respect the prevention and treatment of criminal sexual behavior in adolescent. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Mitigation of Marijuana-Related Legal Harms to Youth in California.

Banys, Peter

2016-01-01

If recreational marijuana is legalized for adults in California, a rational implementation of public policy would neither criminalize youth possession, nor medically pathologize it by conflating possession with addiction. The harms of a criminal justice approach to juveniles should not exceed the harms of the drug itself. Juvenile arrests and probation have consequences: (1) arrest records, probation, and juvenile hall; (2) an incarceration subculture, "crime school," psychological and re-entry costs; (3) school "zero-tolerance" expulsions and suspensions; (4) ineligibility for federal school loans; (5) employment screening problems; (6) racial disparities in arrests; (7) fines and attorney's fees; and (8) immigration/naturalization problems. Marijuana-related arrest rates in California dropped after a 2011 law making possession under 1 oz. an infraction for all, but juvenile marijuana arrests continue to outnumber arrests for hard drugs. Recommendations for prudent implementation policy include: stable marijuana tax funding for Student Assistance Programs (SAPs) in high schools; elimination of "zero-tolerance" suspension/expulsion policies in favor of school retention and academic remediation programs; juvenile justice transparency discriminating among infractions, misdemeanors, and felonies. Criminal sanctions and durations must be proportional to the offense. Probation-based interventions should be reserved for larger possession amounts and recidivist offenders, and outcomes should be independently evaluated.

The independent, nonfederal Task Force on Community Preventive Services (Task Force), which directs the development of the Guide to Community Preventive Services (Community Guide), conducted a systematic review of published scientific evidence concerning the effectiveness of laws and policies that facilitate the transfer of juveniles to the adult criminal justice system to determine whether these transfers prevent or reduce violence among youth who have been transferred and among the juvenile population as a whole. For this review, transfer is defined as placing juveniles aged <18 years under the jurisdiction of the adult criminal justice system. The review followed Community Guide methods for conducting a systematic review of literature and for providing recommendations to public health decision makers. Available evidence indicates that transfer to the adult criminal justice system typically increases rather than decreases rates of violence among transferred youth. Available evidence was insufficient to determine the effect of transfer laws and policies on levels of violent crime in the overall juvenile population. On the basis of these findings, the Task Force recommends against laws or policies facilitating the transfer of juveniles to the adult criminal justice system for the purpose of reducing violence.

Juvenile idiopathic arthritis is a systemic pathology of connective tissue characterized by a chronic inflammatory process with an autoimmune background whereas multiple sclerosis is a demyelination disease with an important role of immune disorders in its pathogenesis. The etiology in both cases remains unknown. The coincidence of juvenile idiopathic arthritis and multiple sclerosis was described a just a few patients. We now report on a 31-year-old woman with juvenile idiopathic arthritis and multiple sclerosis. In the present case, the main problem was to find the right proper medication for a very, aggressive course of multiple sclerosis and for arthritis. Treatment with interferon-beta and methylprednisolone led to remission with just minor side-effects.

This study examined (1) the information present in juvenile court records in Belgium (Flanders) and (2) whether there are differences in information between records that mention a mental disorder and those that do not. The file study sample included 107 court records, and we used a Pearson's chi-square test and a t-test to analyze the information within those records. Information in juvenile court records varied considerably. This variability was evident when we compared juvenile court records with and without mention of a mental disorder. Significantly more information about school-related problems, the functioning of the minor, and the occurrence of domestic violence was included in records that mentioned a mental disorder compared with records that did not. The content of the juvenile court records varied, particularly with regard to the mental health status of the minor in question. We suggest guidelines to standardize the information contained in juvenile court records. Copyright © 2013 Elsevier Ltd. All rights reserved.

Chang, Hsueh-Ling; Chen, Sue-Huei; Huang, Chien

2007-01-01

The etiological factors and interrelations of juvenile delinquents, with psychiatric morbidity and substance abuse have been continuously debated. Cloninger's Tridimensional Theory of Temperament has been reported to predict patterns of substance abuse and comorbidity. In the current study, we aimed to examine the usability of the theory in predicting juvenile delinquency and substance abuse. Sixty consecutive and newly incarcerated male delinquents with history of substance abuse were recruited from a juvenile correctional facility in northwestern Taiwan from January 2002 through December 2003. All subjects were assessed of their temperament, behavioral problems, and psychiatric disorders on an individual base. The juvenile delinquent subjects with childhood history of attention deficit and hyperactivity disorder (ADHD) were significantly younger, consumed less betel nuts, and had more siblings with history of drug abuse. Consistent with the results of Cloninger's studies, novelty seeking positively correlated to the amount of substance abuse, while harm avoidance inversely correlated in juvenile delinquents. Endemic trend of choice of substance abuse needs to be taken into consideration in future research projects.

2010-11-01

This study investigated the predictive validity of youth callous-unemotional (CU) traits, as measured in early adolescence (Grade 7) by the Antisocial Process Screening Device (APSD; Frick & Hare, 2001), in a longitudinal sample (N = 754). Antisocial outcomes, assessed in adolescence and early adulthood, included self-reported general delinquency from 7th grade through 2 years post-high school, self-reported serious crimes through 2 years post-high school, juvenile and adult arrest records through 1 year post-high school, and antisocial personality disorder symptoms and diagnosis at 2 years post-high school. CU traits measured in 7th grade were highly predictive of 5 of the 6 antisocial outcomes-general delinquency, juvenile and adult arrests, and early adult antisocial personality disorder criterion count and diagnosis-over and above prior and concurrent conduct problem behavior (i.e., criterion counts of oppositional defiant disorder and conduct disorder) and attention-deficit/hyperactivity disorder (criterion count). Incorporating a CU traits specifier for those with a diagnosis of conduct disorder improved the positive prediction of antisocial outcomes, with a very low false-positive rate. There was minimal evidence of moderation by sex, race, or urban/rural status. Urban/rural status moderated one finding, with being from an urban area associated with stronger relations between CU traits and adult arrests. Findings clearly support the inclusion of CU traits as a specifier for the diagnosis of conduct disorder, at least with respect to predictive validity.

To facilitate preparing Biological Assessments of proposed channel maintenance projects, the Portland District of the U.S. Army Corps of Engineers contracted the Pacific Northwest National Laboratory to consolidate and synthesize available information about the use of the lower Columbia River and estuary by juvenile anadromous salmonids. The information to be synthesized included existing published documents as well as data from five years (2004-2008) of acoustic telemetry studies conducted in the Columbia River estuary using the Juvenile Salmon Acoustic Telemetry System. For this synthesis, the Columbia River estuary includes the section of the Columbia River from Bonneville Dam at river kilometermore » (Rkm) 235 downstream to the mouth where it enters the Pacific Ocean. In this report, we summarize the seasonal salmonid presence and migration patterns in the Columbia River estuary based on information from published studies as well as relevant data from acoustic telemetry studies conducted by NOAA Fisheries and the Pacific Northwest National Laboratory (PNNL) between 2004 and 2008. Recent acoustic telemetry studies, conducted using the Juvenile Salmon Acoustic Telemetry System (JSATS; developed by the Portland District of the U.S. Army Corps of Engineers), provided information on the migratory behavior of juvenile steelhead (O. mykiss) and Chinook salmon in the Columbia River from Bonneville Dam to the Pacific Ocean. In this report, Section 2 provides a summary of information from published literature on the seasonal presence and migratory behavior of juvenile salmonids in the Columbia River estuary and plume. Section 3 presents a detailed synthesis of juvenile Chinook salmon and steelhead migratory behavior based on use of the JSATS between 2004 and 2008. Section 4 provides a discussion of the information summarized in the report as well as information drawn from literature reviews on potential effects of channel maintenance activities to juvenile salmonids rearing in or migrating through the Columbia River estuary and plume.« less

Can hunting of translocated nuisance Canada geese reduce local conflicts?

USGS Publications Warehouse

Holevinski, R.A.; Malecki, R.A.; Curtis, P.D.

2006-01-01

Resident Canada geese (Branta canadensis) nest or reside in the temperate latitudes of North America. In past years, translocation-the capture and subsequent release of geese at distant locations-has been used to establish resident goose populations and to reduce nuisance problems. However, with new special hunting seasons designed to target resident Canada geese, we can now evaluate translocation as a management tool when hunting is allowed at release sites. We selected 2 study sites, representative of urban and suburban locations with nuisance resident geese, in central and western New York, USA. In June 2003, we translocated 80 neck-banded adult geese, 14 radiomarked adult females, and 83 juveniles 150 km east and southwest from urban and suburban problem sites in western New York to state-owned Wildlife Management Areas. At these same capture sites, we used 151 neck-banded adult geese, 12 radiomarked females, and 100 juveniles as controls to compare dispersal movements and harvest vulnerability to translocated geese. All observations (n = 45) of translocated radiomarked geese were <20 km from release sites, in areas where hunting was permitted. Only 25 of 538 observations (4.6%) of radiomarked geese at control sites were in areas open to hunting. The remainder of observations occurred at nonhunting locations within 10 km of control sites. More translocated adult geese (23.8%) were harvested than control geese (6.6%; ??2 = 72.98, P = 0.0009). More translocated juvenile geese were harvested (22.9%) than juvenile controls (5.0%; ??2 = 72.30, P = 0.0005). Only 7 (8.8%) translocated adult geese returned to the original capture sites during Canada goose hunting seasons. Translocation of adult and juvenile geese in family groups may alleviate nuisance problems at conflict sites through increased harvest, reducing the number of birds returning in subsequent years.

2011-07-01

Incarcerated adolescents show a high prevalence rate of psychopathology and comorbid psychiatric conditions. Child and adolescent psychiatrists working in the penal system are confronted with the need to provide care and to develop specific treatment plans. The data gathered from incarcerated juveniles were analyzed with a special focus on gender-specific treatment aspects. The Mini-International Neuropsychiatric Interview for children and adolescents was used to assess psychopathology in detained juveniles in Austria. The final study sample consisted of 333 juveniles (58 girls and 275 boys). 90 % of the juveniles in our sample suffered from at least one psychiatric disorder, and more than 60 % were diagnosed with two or more simultaneous psychiatric disorders. Using factor analyses we found three clinically relevant disorder patterns according to psychopathological characteristics for males: ADHD/conduct disorder and drug abuse; anxiety and depression; separation anxiety disorder/PTSD and alcohol abuse. In females, we found four disorder patterns: separation anxiety disorder/social phobia/dysthymia; PTSD and drug abuse in combination with either ADHD or conduct disorder; depression and alcohol abuse. Considering that juvenile detainees are burdened by high rates of psychopathology and comorbidity, it is essential to develop a substantiated diagnostic procedure in order when making treatment decisions; different disorder patterns must be considered in conjunction with detained juveniles. The patterns of psychopathology observed might be related to different characteristics in the development of delinquent behavior, in treatment needs, and legal prognosis.

An Enriched Environment Promotes Shelter-Seeking Behaviour and Survival of Hatchery-Produced Juvenile European Lobster (Homarus gammarus)

The high loss of newly released hatchery-reared European lobster (Homarus gammarus) juveniles for stock enhancement is believed to be the result of maladaptive anti-predator behaviour connected to deprived stimuli in the hatchery environment. Our objective was to learn if an enriched hatchery environment enhances shelter-seeking behaviour and survival. In the “naïve” treatment, the juveniles were raised in single compartments without substrate and shelter whereas juveniles in the “exposed” treatment experienced substrate, shelter and interactions with conspecifics. Three experiments with increasing complexity were conducted. Few differences in shelter-seeking behaviour were found between treatments when one naïve or one exposed juvenile were observed alone. When observing interactions between one naïve and one exposed juvenile competing for shelter, naïve juveniles more often initiated the first aggressive encounter. The third experiment was set up to simulate a release for stock enhancement. Naïve and exposed juveniles were introduced to a semi-natural environment including substrate, a limited number of shelters and interactions with conspecifics. Shelter occupancy was recorded three times during a period of 35 days. Exposed juveniles occupied more shelters, grew larger and had higher survival compared with naïve juveniles. Our results demonstrate that experience of environmental complexity and social interactions increase shelter-seeking ability and survival in hatchery reared lobster juveniles. PMID:27560932

1999-01-01

From 1993 to 1995, field surveys were conducted in western Madagascar to assess the current status of the angonoka tortoise (Geochelone yniphora) in the wild. Tortoise presence was documented at 10 of 11 localities surveyed. These localities represent at least five populations, all within a 30-km radius of Baly Bay, near the town of Soalala. The populations occur on fragments of habitat ranging from <50 to 4–6000 ha in size. One hundred and forty-five tortoises were marked in the five populations. Hatchling or juvenile tortoises were observed in all populations, indicating that reproduction was occurring. Most of the 145 tortoises (68%) were marked on Cape Sada, where monthly surveys were conducted. The tortoise density on the c. 150 ha peninsula was 0.66 tortoises/ha. The remains of 22 dead juveniles were found on Cape Sada over the 2-year period. This evidence, combined with the low number of juveniles in intermediate size classes in the Cape Sada population suggests that juvenile mortality may be high.

Juvenile spondyloarthropathies are mainly manifested by symptoms of peripheral arthritis and enthesitis. Early involvement of sacroiliac joints and spine is exceptionally rare in children; this usually happens in adulthood. Conventional radiographs visualize late inflammatory lesions. Early diagnosis is possible with the use of ultrasonography and magnetic resonance imaging. The first part of the article presented classifications and radiographic presentation of juvenile spondyloarthropathies. This part discusses changes seen on ultrasonography and magnetic resonance imaging. In patients with juvenile spondyloarthropathies, these examinations are conducted to diagnose inflammatory lesions in peripheral joints, tendon sheaths, tendons and bursae. Moreover, magnetic resonance also shows subchondral bone marrow edema, which is considered an early sign of inflammation. Ultrasonography and magnetic resonance imaging do not show specific lesions for any rheumatic disease. Nevertheless, they are conducted for early diagnosis, treatment monitoring and identifying complications. This article presents a spectrum of inflammatory changes and discusses the diagnostic value of ultrasonography and magnetic resonance imaging. PMID:29075522

Health care needs assessment among adolescents in correctional institutions in Zambia: an ethical analysis.

PubMed

Kumwenda, Maureen; Nzala, Selestine; Zulu, Joseph M

2017-08-22

While health care needs assessments have been conducted among juveniles or adolescents by researchers in developed countries, assessments using an ethics framework particularly in developing countries are lacking. We analysed the health care needs among adolescents at the Nakambala Correctional Institution in Zambia, using the Beauchamp and Childress ethics framework. The ethics approach facilitated analysis of moral injustices or dilemmas triggered by health care needs at the individual (adolescent) level. The research team utilized 35 in-depth interviews with juveniles, 6 key informant interviews and 2 focus group discussions to collect data. We analysed the data using thematic analysis. The use of three sources of data facilitated triangulation of data. Common health problems included HIV/AIDS, STIs, flu, diarrhoea, rashes, and malaria. Although there are some health promotion strategies at the Nakambala Approved School, the respondents classified the health care system as inadequate. The unfavourable social context which included clouded rooms and lack of adolescent health friendly services unfairly exposed adolescents to several health risks and behaviours thus undermining the ethics principle of social justice. In addition, the limited prioritisation of adolescent centres by the stakeholders and erratic funding also worsened injustices by weakening the health care system. Whereas the inadequate medical and drug supplies, shortage of health workers in the nearby health facilities and weak referral systems excluded the juveniles from enjoying maximum health benefits thus undermining adolescents' wellbeing or beneficence. Inadequate medical and drug supplies as well as non-availability of adolescent friendly health services at the nearest health facility did not only affect social justice and beneficence ethics principles but also threatened juveniles' privacy, liberty and confidentiality as well as autonomy with regard to health service utilisation. Adequately addressing the health needs in correctional institutions may require adopting an ethics framework in conducting health needs assessment. An ethics approach is important because it facilitates understanding of moral dilemmas that arise due to health needs. Furthermore, strategies for addressing health needs related to one ethics principle may have a positive ripple effect over other health needs as the principles are intertwined thus facilitating a comprehensive response to health needs.

Nurturing for Careers in Drug Use and Crime: Conduct Norms for Children and Juveniles in Crack-Using Households

PubMed Central

Johnson, Bruce D.; Dunlap, Eloise; Maher, Lisa

2009-01-01

A very sizable proportion of juvenile delinquents and adult criminals come from backgrounds and family kin systems having deviant parents or kin. This paper provides a focus upon the child-rearing practices directly observed by trained ethnographer during a case study of one highly criminal, drug-using household/kin network. The concrete expectations (and actual practices)—called conduct norms—with which the household adults respond to (or “nurture”) children and juveniles are delineated. While children are taught to “pay attention” to what adults do, adults typically model various deviant activities and rarely engage in conventional behaviors. Drug-using, and especially crack-using, men and women are expected not to raise (or financially support) children born to them; other kin expect to raise children of such unions. Children are not expected, nor able, to develop strong affective bonds with any household adults, and receive little or no psychological parenting. Adults do not take strong measures to protect children/juveniles from harm, and often adults are a major source of harm. In many ways the conduct norms in such crack-using households are well designed to “nurture” those persons who will be antisocial as children, delinquents as juveniles, and become criminals, drug misusers, and prostitutes in adulthood—and who have very few chances to become conventional adults.

Branded for Life: The Case of Detained Black Youth.

ERIC Educational Resources Information Center

Swan, L. Alex

The concept represented by the term juvenile delinquency covers a wide range of activities and a complex set of juvenile offenses. Moreover, the concept is vague and its definition is often left to the discretion of law enforcement agencies and the courts. A problem for black youth is that their acts are assessed by outsiders who have the power to…

Rawal, Purva; Romansky, Jill; Jenuwine, Michael; Lyons, John S

2004-01-01

Mental health placement rates by the juvenile justice system differ by race. However, it is unknown whether mental health needs differ by race. This study attempted to investigate potential differences in mental health needs and service utilization among Caucasian, African American, and Hispanic juvenile justice involved youth. A stratified random sample of 473 youth petitioned, adjudicated, and incarcerated from 1995-1996 was examined using a standard chart review protocol and the Childhood Severity of Psychiatric Illness measure for mental health needs. Significant and unique mental health needs were demonstrated for all racial groups. African American youth demonstrated the greatest level of needs. Minority status indicated significantly lower rates of mental health service utilization. Minority youth in the juvenile justice system are most at risk for underserved mental health needs. Based on the current data, it can be inferred that the first contact with the state's child and adolescent serving system, which includes the juvenile justice and mental health sectors, appears to be through the juvenile justice sector for many minority youth with delinquency problems.

Spatial distribution of juvenile and adult female Tanner crabs (Chionoecetes bairdi) in a glacial fjord ecosystem: Implications for recruitment processes

USGS Publications Warehouse

Nielsen, J.K.; Taggart, S. James; Shirley, Thomas C.; Mondragon, Jennifer

2007-01-01

A systematic pot survey in Glacier Bay, Alaska, was conducted to characterize the spatial distribution of juvenile and adult female Tanner crabs, and their association with depth and temperature. The information was used to infer important recruitment processes for Tanner crabs in glaciated ecosystems. High-catch areas for juvenile and adult female Tanner crabs were identified using local autocorrelation statistics. Spatial segregation by size class corresponded to features in the glacial landscape: high-catch areas for juveniles were located at the distal ends of two narrow glacial fjords, and high-catch areas for adults were located in the open waters of the central Bay. Juvenile female Tanner crabs were found at nearly all sampled depths (15–439 m) and temperatures (4–8°C), but the biggest catches were at depths <150 m where adults were scarce. Because adults may prey on or compete with juveniles, the distribution of juveniles could be influenced by the distribution of adults. Areas where adults or predators are scarce, such as glacially influenced fjords, could serve as refuges for juvenile Tanner crabs.

Innovative problem solving by wild spotted hyenas

2012-01-01

Innovative animals are those able to solve novel problems or invent novel solutions to existing problems. Despite the important ecological and evolutionary consequences of innovation, we still know very little about the traits that vary among individuals within a species to make them more or less innovative. Here we examine innovative problem solving by spotted hyenas (Crocuta crocuta) in their natural habitat, and demonstrate for the first time in a non-human animal that those individuals exhibiting a greater diversity of initial exploratory behaviours are more successful problem solvers. Additionally, as in earlier work, we found that neophobia was a critical inhibitor of problem-solving success. Interestingly, although juveniles and adults were equally successful in solving the problem, juveniles were significantly more diverse in their initial exploratory behaviours, more persistent and less neophobic than were adults. We found no significant effects of social rank or sex on success, the diversity of initial exploratory behaviours, behavioural persistence or neophobia. Our results suggest that the diversity of initial exploratory behaviours, akin to some measures of human creativity, is an important, but largely overlooked, determinant of problem-solving success in non-human animals.

Hematology and blood biochemistry of captive mugger crocodiles (Crocodylus palustris).

PubMed

Stacy, B A; Whitaker, N

2000-09-01

Comprehensive hematologic and biochemical analyses were conducted on blood from 23 male and 31 female clinically stable captive mugger crocodiles (Crocodylus palustris). Erythrocyte mean corpuscular volume (MCV), potassium, cholesterol, and calcium concentrations were significantly greater in juvenile males than in juvenile females, but no significant differences were determined between parameters of subadult males and subadult females. The mean WBC count and mean heterophil count were significantly higher in adult males than in adult females. Mean uric acid concentration was significantly greater in adult females than in males. Mean erythrocyte count was significantly higher in adults than in juveniles. Adult mean WBC and lymphocyte counts were significantly lower than those of both juveniles and subadults. Subadults had significantly lower mean eosinophil counts than both adults and juveniles. Subadults had significantly lower mean alkaline phosphatase activities than juveniles, whereas the adults had significantly lower aspartate aminotransferase and alanine aminotransferase activities than other groups. Lactate dehydrogenase activities were significantly lower for subadults than for juveniles and adults. Cholesterol concentrations were significantly higher for subadults and juveniles compared with adults. Triglyceride concentration was significantly lower for subadults and highest for juveniles. Glucose concentrations were significantly higher for adults. Blood urea nitrogen was significantly lower for subadults than for both adults and juveniles. Uric acid concentrations were significantly higher for juveniles than for the subadults and adults. The subadult animals also had a significantly lower potassium concentration. The results obtained were then compared with known values for other crocodilian species.

Sports Participation and Juvenile Delinquency: A Meta-Analytic Review.

Spruit, Anouk; van Vugt, Eveline; van der Put, Claudia; van der Stouwe, Trudy; Stams, Geert-Jan

2016-04-01

Participation in sports activities is very popular among adolescents, and is frequently encouraged among youth. Many psychosocial health benefits in youth are attributed to sports participation, but to what extent this positive influence holds for juvenile delinquency is still not clear on both the theoretical and empirical level. There is much controversy on whether sports participation should be perceived as a protective or a risk factor for the development of juvenile delinquency. A multilevel meta-analysis of 51 published and unpublished studies, with 48 independent samples containing 431 effect sizes and N = 132,366 adolescents, was conducted to examine the relationship between sports participation and juvenile delinquency and possible moderating factors of this association. The results showed that there is no overall significant association between sports participation and juvenile delinquency, indicating that adolescent athletes are neither more nor less delinquent than non-athletes. Some study, sample and sports characteristics significantly moderated the relationship between sports participation and juvenile delinquency. However, this moderating influence was modest. Implications for theory and practice concerning the use of sports to prevent juvenile delinquency are discussed.

Drug abuse in Costa Rica: a review of several studies.

Alfaro Murillo, E

1990-01-01

This article provides a review of drug use surveys conducted by Costa Rica's Institute on Alcoholism and Drug Dependence during the years 1983-1987. These studies dealt with a wide range of subjects--residents of marginal neighborhoods, juvenile male and adult female detainees, and high school students--as well as with the general population. Overall, the studies indicated that the most commonly used illicit drug was marijuana, that the bulk of the drug users (excluding alcohol and tobacco users) were young males, that relevant levels of cocaine use were starting to occur, and that the country's general drug abuse picture poses a problem in need of immediate attention.

2014-01-01

There is increasing recognition that family violence may be perpetrated by juveniles against their parents and siblings, however empirical research regarding the nature and causes of such violence is relatively limited. This study examines juvenile family violence in the context of an Intervention Order (IO) being sought against a relative aged 18years or less. All cases over a 3-year period involving an IO application in a major metropolitan Children's Court in Australia were analysed (n=438). The majority of applicants/victims were parents (78%) and to a lesser extent siblings (11%) and other relatives (9%). Most parents who sought applications were mothers (63%) and one-parent households were over-represented (66%). The majority of defendants/perpetrators were male (69%), though juvenile females constituted a significant minority (31%). Intervention orders were sought to prohibit property damage (61%), physical assaults (59%) and/or threats (53%). According to the victim reports, these behaviours emerged in the context of prolonged behavioural problems (49%), a desire to intimidate the victim (12%) or retaliation (8%). While 44% of IO applications were granted, the majority were not (56%) due to the victim discontinuing the application prior to a formal hearing. Of the orders that were granted, a third (32%) were subsequently reported as having been breached. Juvenile family violence is a serious social problem that requires more systematic research to identify the correlates of this behaviour and effective interventions to prevent or reduce its occurrence.

2003-01-01

The Empiric Stream Treatment Ranking (ESTR) system is a data-driven, model-based, decision tool for selecting Great Lakes streams for treatment with lampricide, based on estimates from larval sea lamprey (Petromyzon marinus) surveys conducted throughout the basin. The 2000 ESTR system was described and applied to larval assessment surveys conducted from 1996 to 1999. A comparative analysis of stream survey and selection data was conducted and improvements to the stream selection process were recommended. Streams were selected for treatment based on treatment cost, predicted treatment effectiveness, and the projected number of juvenile sea lampreys produced. On average, lampricide treatments were applied annually to 49 streams with 1,075 ha of larval habitat, killing 15 million larval and 514,000 juvenile sea lampreys at a total cost of $5.3 million, and marginal and mean costs of $85 and $10 per juvenile killed. The numbers of juvenile sea lampreys killed for given treatment costs showed a pattern of diminishing returns with increasing investment. Of the streams selected for treatment, those with > 14 ha of larval habitat targeted 73% of the juvenile sea lampreys for 60% of the treatment cost. Suggested improvements to the ESTR system were to improve accuracy and precision of model estimates, account for uncertainty in estimates, include all potentially productive streams in the process (not just those surveyed in the current year), consider the value of all larvae killed during treatment (not just those predicted to metamorphose the following year), use lake-specific estimates of damage, and establish formal suppression targets.

The blind men and the elephant: Concerns about the use of juvenile proportion data

McCaffery, Brian J.; Handel, Colleen M.; Gill, Robert E.; Ruthrauff, Daniel R.

2007-01-01

Juvenile proportion data in shorebirds are being used with increasing frequency to estimate recruitment and even breeding success. Although this area of investigation holds great promise, flaws in current study designs preclude great confidence in the broad-scale inferences being drawn. We present data from our own investigations on juvenile proportions in Bar-tailed Godwits Limosa lapponica in Alaska to illustrate the significance of some of these problems. We then explore issues of study design, specifically bias, precision, untested assumptions and the use of correlations for interpreting juvenile proportion data. The issue of bias is particularly important, because inferences about shorebird productivity are being expanded to geographic areas well beyond what the data legitimately allow. Until studies of juvenile proportions are more rigorously designed and implemented, we suggest that many of the inferences about shorebird productivity based on such data are premature and may lead to management decisions that are detrimental to the conservation of shorebirds.

Species-specific and transgenerational responses to increasing salinity in sympatric freshwater gastropods

USGS Publications Warehouse

Suski, Jamie G.; Salice, Christopher J.; Patino, Reynaldo

2012-01-01

Freshwater salinization is a global concern partly attributable to anthropogenic salt contamination. The authors examined the effects of increased salinity (as NaCl, 250-4,000 µS/cm, specific conductance) on two sympatric freshwater gastropods (Helisoma trivolvis and Physa pomillia). Life stage sensitivities were determined by exposing naive eggs or naive juveniles (through adulthood and reproduction). Additionally, progeny eggs from the juvenile-adult exposures were maintained at their respective parental salinities to examine transgenerational effects. Naive H. trivolvis eggs experienced delayed development at specific conductance > 250 µS/cm; reduced survivorship and reproduction were also seen in juvenile H. trivolvis at 4,000 µS/cm. Survival and growth of P. pomilia were not affected by increased salinity following egg or juvenile exposures. Interestingly, the progeny of H. trivolvis exposed to higher salinity may have gained tolerance to increased salinity whereas P. pomilia progeny may have experienced negative transgenerational effects. The present study demonstrates that freshwater snail species vary in their tolerance to salinization and also highlights the importance of multigenerational studies, as stressor impacts may not be readily apparent from shorter term exposures.

Reclaiming futures: communities helping teens overcome drugs, alcohol and crime--a new practice framework for juvenile justice.

PubMed

Nissen, Laura Burney

2007-03-01

Increasing numbers of youth entering the juvenile justice system on drug-related charges require new practice frameworks for youth advocates. Screening, assessment and intervention capabilities have not kept pace with the youth who need them. This article presents an overview of a new approach, based on the system of care movement, to integrated care service provision for this population. Utilizing the Reclaiming Futures initiative--being piloted in 10 communities in the United States--as a model for change, the article suggests that juvenile justice, in partnership with treatment and other community stakeholders, can have a positive impact on this social problem.

Progress and perils in the juvenile justice and mental health movement.

PubMed

Grisso, Thomas

2007-01-01

The juvenile justice system in the United States is experiencing a social movement aimed at responding to the mental and emotional problems of delinquent youths. Ironically, this movement arose in the wake of a decade of reform in juvenile justice that had set aside the system's 100-year tradition of rehabilitation for delinquents in the interests of their punishment and a primary emphasis on public safety. This article describes the recent juvenile justice and mental health movement, discusses the circumstances that motivated it, and provides examples of its progress. Now that the movement has taken hold, however, its future is threatened by several unintended consequences of the motives and strategies of those who succeeded in promoting the movement. Those potential perils are described with an eye to reducing their impact, thereby sustaining the movement and its potentially positive effects.

Host fish suitability for glochidia of Ligumia recta

USGS Publications Warehouse

Khym, J.R.; Layzer, J.B.

2000-01-01

In the early 1900s several hosts were identified for the black sandshell Ligumia recta. Recent attempts to propagate juvenile L. recta with two of the reported hosts (bluegill Lepomis macrochirus and largemouth bass Micropterus salmoides) have produced inconsistent results and few juveniles. We conducted this study to determine which of the reported hosts or other fish hosts were the most suitable for glochidial metamorphosis. The duration of glochidial metamorphosis varied among seasons. Despite similar water temperatures, juveniles metamorphosed sooner and over a shorter period of time in the spring than early fall; the modal day of metamorphosis differed by 78 d. Relatively few juveniles were recovered from bluegill and largemouth bass in three trials. White crappie Pomoxis annularis and black crappie P. nigromaculatus were marginally suitable hosts. Although glochidia encysted on all hosts, >10x more juveniles metamorphosed on sauger Stizostedion canadense compared to other hosts tested.

2012-04-01

Most studies assessing the burden of psychiatric disorders in juvenile correctional facilities have been based on small or male-only samples or have focused on a single disorder. Using electronic data routinely collected by the Texas juvenile correctional system and its contracted medical provider organization, we estimated the prevalence of selected psychiatric disorders among youths committed to Texas juvenile correctional facilities between January 1, 2004, and December 31, 2008 (N = 11,603). Ninety-eight percent were diagnosed with at least one of the disorders. Highest estimated prevalence was for conduct disorder (83.2%), followed by any substance use disorder (75.6%), any bipolar disorder (19.4%), attention-deficit/hyperactivity disorder (18.3%), and any depressive disorder (12.6%). The estimated prevalence of psychiatric disorders among these youths was exceptionally high and showed patterns by sex, race/ethnicity, and age that were both consistent and inconsistent with other juvenile justice samples.

Youth Offender Care Needs Assessment Tool (YO-CNAT): an actuarial risk assessment tool for predicting problematic child-rearing situations in juvenile offenders on the basis of police records.

PubMed

van der Put, Claudia E; Stams, Geert Jan J M

2013-12-01

In the juvenile justice system, much attention is paid to estimating the risk for recidivism among juvenile offenders. However, it is also important to estimate the risk for problematic child-rearing situations (care needs) in juvenile offenders, because these problems are not always related to recidivism. In the present study, an actuarial care needs assessment tool for juvenile offenders, the Youth Offender Care Needs Assessment Tool (YO-CNAT), was developed to predict the probability of (a) a future supervision order imposed by the child welfare agency, (b) a future entitlement to care indicated by the youth care agency, and (c) future incidents involving child abuse, domestic violence, and/or sexual norm trespassing behavior at the juvenile's address. The YO-CNAT has been developed for use by the police and is based solely on information available in police registration systems. It is designed to assist a police officer without clinical expertise in making a quick assessment of the risk for problematic child-rearing situations. The YO-CNAT was developed on a sample of 1,955 juvenile offenders and was validated on another sample of 2,045 juvenile offenders. The predictive validity (area under the receiver-operating-characteristic curve) scores ranged between .70 (for predicting future entitlement to care) and .75 (for predicting future worrisome incidents at the juvenile's address); therefore, the predictive accuracy of the test scores of the YO-CNAT was sufficient to justify its use as a screening instrument for the police in deciding to refer a juvenile offender to the youth care agency for further assessment into care needs.

Blood samples were obtained from adult (> 1.5 years) and juvenile (2-8 weeks, 9-16 weeks and 17-24 weeks) captive buff-crested bustards (Eupodotis ruficrista gindiana) to study age-related changes. A total of twelve different tests were conducted using a Hitachi 90011 wet chemistry analyzer. A comparison of the values obtained was made between adult and juvenile buff-crested bustards and from the literature with other bustard species. Significant differences between adult and juvenile buff-crested bustards were found for glucose, uric acid, total protein, alkaline phosphatase, asparatate amino transferase and calcium. The results obtained from this study provide blood chemistry values for this species and demonstrate age-related differences between adult and juvenile birds.

To examine the medical status and history of health care utilization of adolescents at the time of their admission to a juvenile detention facility. Data were collected over an 18-month period on all detainees admitted for the first time to a juvenile detention facility in a major southeastern city in the United States. Information was gathered through a private, confidential interview completed by a medical social worker and a physical examination by a physician. Information was obtained regarding past medical history, complaints at the time of admission, health care utilization, and physical examination. Approximately 10% of teenagers admitted to a detention facility have a significant medical problem (excluding drug/alcohol abuse, or uncomplicated sexually transmitted diseases) that requires medical follow-up. The majority of these conditions were known to the adolescent at the time of admission. Only a third of adolescents admitted to the detention facility reported a regular source of medical care, and only about 20% reported having a private physician. A majority of all the detainees had already fallen behind in or dropped out of school. More than half of the families of the adolescents with a medical problem appeared to be unable or unwilling to assist in ensuring proper medical follow-up. A significant percentage of adolescents entering a detention facility have a medical problem requiring health care services. Detention facilities offer an opportunity to deliver and coordinate medical care to high-risk adolescents. Programs linking public and private health care providers with the correctional care system may provide juveniles with an acceptable option for obtaining needed health care services.

Juvenile delinquency among students of an approved sheltered girls' school in Lagos, Nigeria.

PubMed

Ebuehi, O M; Omogbemi, K B

2011-01-01

Juvenile delinquency is the involvement of a child younger than 18 years in behavior that violates the law. Its cost in terms of human potential, public safety and tax expenditures can be very high. Research that assesses how and why children become delinquent is a sound investment, because it can provide the foundation for effective intervention in its prevention and control. The study is to determine the factors associated with juvenile delinquency. A cross-sectional study was conducted among sixty (60) students of the approved sheltered girls' school, Idi-Araba, Lagos, using a structured interviewer-administered questionnaire. Findings revealed that the respondents were within the ages of 10-18 years with a mean age of 14.2 +/- 2.0 years, 70% had attained primary school education. Of the 53.3% that dropped out of school, 65.6% did so from financial problems, 6.3% as a result of poor performance and peer pressure accounted for 28.1%. A total of 71.7% of the students were brought to the school by the police; 52.5% on account of roaming while lack of parental control, stealing, robbery and fighting accounted for 16.9%, 11.9%, 10.2%, and 8.5% respectively. Majority (58.6%) of the students had both parents alive while 12.1% had both parents deceased. About 25 (41.7%) of the respondents admitted to committing a crime out of which 88% was stealing, 4% were involved in armed robbery and 8% in house breaking. Of all the socio-demographics characteristics of the respondents explored, only their educational level was found to be significantly associated (p = 0.0197) with criminal behaviour. Mother's educational level (p = 0.0245), maternal alcohol consumption (p = 0.0173) and kind of treatment (0.0245) received from step mums were significantly associated with criminal behaviour. Poor parental supervision, poverty and peer pressure played key roles in delinquency among the juveniles. An effective prevention and control of juvenile delinquency will require collective efforts involving all stakeholders (family, government and non-governmental organizations) in child development.

Spatial patterns of native freshwater mussels in the Upper Mississippi River

Multiple physical and biological factors structure freshwater mussel communities in large rivers, and their distributions have been described as clumped or patchy. However, few surveys of mussel populations have been conducted over areas large enough and at resolutions fine enough to quantify spatial patterns in their distribution. We used global and local indicators of spatial autocorrelation (i.e., Moran’s I) to quantify spatial patterns of adult and juvenile (≤5 y of age) freshwater mussels across multiple scales based on survey data from 4 reaches (navigation pools 3, 5, 6, and 18) of the Upper Mississippi River, USA. Native mussel densities were sampled at a resolution of ∼300 m and across distances ranging from 21 to 37 km, making these some of the most spatially extensive surveys conducted in a large river. Patch density and the degree and scale of patchiness varied by river reach, age group, and the scale of analysis. In all 4 pools, some patches of adults overlapped patches of juveniles, suggesting spatial and temporal persistence of adequate habitat. In pools 3 and 5, patches of juveniles were found where there were few adults, suggesting recent emergence of positive structuring mechanisms. Last, in pools 3, 5, and 6, some patches of adults were found where there were few juveniles, suggesting that negative structuring mechanisms may have replaced positive ones, leading to a lack of localized recruitment. Our results suggest that: 1) the detection of patches of freshwater mussels requires a multiscaled approach, 2) insights into the spatial and temporal dynamics of structuring mechanisms can be gained by conducting independent analyses of adults and juveniles, and 3) maps of patch distributions can be used to guide restoration and management actions and identify areas where mussels are most likely to influence ecosystem function.

Spirituality, adolescent suicide, and the juvenile justice system.

PubMed

Wahl, Richard A; Cotton, Sian; Harrison-Monroe, Patricia

2008-07-01

Spirituality is often overlooked as a coping method and resilience factor in the lives of adolescents. An improved understanding of the role of spirituality in the lives of adolescents will help in understanding the choices many teens face during times of personal crisis. Youth entering the juvenile justice system often present with high rates of mental health problems and suicidal ideation. Two clinical vignettes of adolescents who exhibited suicidal ideation while in juvenile detention are discussed. An understanding of the role of spirituality for an adolescent in crisis can greatly enhance our ability to provide culturally competent care and offer meaningful support. This becomes increasingly important as the juvenile detention population becomes ever more diverse. Valuable information can be obtained by taking a "clinical spiritual history" which enables clinicians to have a clearer understanding of an adolescent's worldview and provide the necessary therapeutic interventions. Specific questions are suggested as a basis for obtaining this information.

Mental health needs of Native American youth in the Oregon juvenile justice system are compared to those of Euro-American youth. The comparison is between 109 Euro-American youth and 22 Native American youth drawn from two samples of youth adjudicated to community service and incarcerated. The youth completed a mental health history and indices of mental health and health status. Native American youth are disproportionately represented in the Oregon juvenile justice system. Mental health profiles of Native American youth reflect problems at least as severe as those of Euro-American youth, and both Native American and Euro-American youth in the juvenile justice system had profiles different from those of youth not referred for clinical services. More Native American youth (42.5%) compared to Euro-American youth (27.5%) reported considering suicide in the past 12 months. Mental health screenings for both Native American and Euro-American youth are indicated.

Reference toxicant testing using juvenile freshwater mussels was conducted as part of the CR-ERP biomonitoring study of Clinch River sediments to assess the sensitivity of test organisms and the overall performance of the test. Tests were conducted using moderately hard synthetic water spiked with known concentrations of copper as copper sulfate. Two different foods, phytoplankton and YCT-Selenastrum (YCT-S), were tested in side by side tests to compare food quality. Toxicity testing of copper sulfate reference toxicant was conducted from July 6--15, 1993. The organisms used for testing were juvenile fresh-water mussels (Anodonta imbecillis). Although significant reduction in growth, compared tomore » the phytoplankton control, was seen in all treatments, including the YCT-S Control, the consequence of this observation has not been established. Ninety-day testing of juvenile mussels exhibited large variations in growth within treatment and replicate groups.

Lost opportunities for intervention: undetected markers for the development of serious juvenile delinquency.

PubMed

Stouthamer-Loeber, Magda; Loeber, Rolf

2002-01-01

Persistent serious delinquency in young males rarely starts without a history of problem behaviour in childhood. This paper addresses the following questions: (1) At what age does persistent serious offending emerge for the first time? (2) What proportion of persistent serious delinquent boys qualifies for a diagnosis of a disruptive behaviour disorder? (3) What proportion of persistent serious delinquent boys receive help for their behavioural or educational problems, either from mental health professionals or from personnel at school? Eight waves of assessments from the oldest sample (ages 13 to 18.5) of the Pittsburgh Youth Study were used to classify boys as persistent serious violent offenders, persistent serious property offenders, persistent non-serious offenders, and non-offenders based on their self-reports. Juvenile court records, diagnostic information and information about help for mental health problems were used. Almost half of the boys who eventually become a persistent serious offender already have an onset of their serious delinquent behaviour by age 12. Two-thirds of the boys who come to the attention of the juvenile court already had behaviour problems for at least five years, and one-third were diagnosed as having a disruptive behaviour disorder by age 13. However, less than half of the persistent serious delinquents had received any help from either mental health professionals or from personnel in schools. Early behaviour problems and a diagnosis of disruptive behaviour disorder constitute targets for intervention. The relatively low rate of interventions for boys with these problems and who later become persistent serious offenders indicates a high under-utilization of opportunities to prevent serious delinquency by parents and professionals.

Promoting Healthy Outcomes Among Youth with Multiple Risks: Innovative Approaches

PubMed Central

Greenberg, Mark T.; Lippold, Melissa A.

2015-01-01

Adolescent behavior problems such as substance use, antisocial behavior problems, and mental health problems have extremely high social costs and lead to overburdened mental health and juvenile justice systems in the United States and Europe. The prevalence of these problems is substantial, and at-risk youth often present with a combination of concerns. An understanding of risk and protective factors at multiple levels, including the child, family, peer, school, and community, has influenced intervention development. At the individual and family levels, the most effective and cost-effective programs work intensively with youth and their families or use individual and group cognitive-behavioral approaches. However, there is a paucity of careful studies of effective policies and programs in the juvenile justice system. Research is needed that focuses on adoption, financing, implementation, and sustainable use of evidence-based programs in public service systems. In addition, the field needs to understand better for whom current programs are most effective to create the next generation of more effective and efficient programs. PMID:23297659

Psychosocial adversity, delinquent pathway and internalizing psychopathology in juvenile male offenders.

PubMed

Lemos, Ida; Faísca, Luis

2015-01-01

The main aim of the present study was to investigate the presence of a set of risk factors relating to childhood life events and other psychosocial factors that may be associated with criminal indicators and with the prevalence of internalizing psychopathology in a sample of adolescent offenders. Fifty male adolescents in the custody of the Portuguese Juvenile Justice System participated in the study (M=15.8 years of age). The Adolescent Psychopathology Scale - Short Form (APS-SF) was administered in a structured interview format, and the sociodemographic, family and criminal data questionnaire was filled in by the justice professional after consulting the adolescent's file. Forty-six percent of all subjects had previous delinquent behavior. About 32% of the boys had committed violent offenses and 88% acted with peers. Also, the persistence of the delinquent behavior (50% of the offenders), coupled with the increase in the severity of the crimes committed (38% of the sample), suggests that these adolescents were at risk for serious and chronic delinquency at the time of the intervention. About 32% of the participants reported posttraumatic stress disorder symptoms, 20% had suicide ideation, and a lower percentage reported other internalizing problems. Institutionalization, maltreatment and conduct problems in childhood, and family risk factors (parental conflict, absence of a father figure, lack of parental control and family substance addiction) were related with the report of internalizing problems. Moreover, the increase in the severity of criminal offenses and living in a correctional facility were associated with higher levels of posttraumatic stress, interpersonal problems, anxiety and depression. This study draws attention to the importance of assessing indicators of psychopathology and of psychosocial risk in intervention programs with young offenders, but also to the need of family focused interventions in order to help prevent recidivism.

According to the risk-need-responsivity model of offender, assessment and rehabilitation treatment should target specific factors that are related to re-offending. This study evaluates the residential care of Filipino juvenile offenders using the risk-need-responsivity model. Risk analyses and criminogenic needs assessments (parenting style, aggression, relationships with peers, empathy, and moral reasoning) have been conducted using data of 55 juvenile offenders in four residential facilities. The psychological care has been assessed using a checklist. Statistical analyses showed that juvenile offenders had a high risk of re-offending, high aggression, difficulties in making pro-social friends, and a delayed socio-moral development. The psychological programs in the residential facilities were evaluated to be poor. The availability of the psychological care in the facilities fitted poorly with the characteristics of the juvenile offenders and did not comply with the risk-need-responsivity model. Implications for research and practice are discussed. Copyright © 2016 Elsevier Ltd. All rights reserved.

The research carried out in Poland reflected that sexual initiation before 18 years of age is a common phenomenon and refers to roughly 80% of teenagers. In Poland there is no uniform standing of medical and legal environments with regard to dealing with a juvenile patient who has become sexually active and expects the advice of a gynaecologist, gynaecologic examination and often asks for prescribing contraceptives. The procedures must take into account the fact that in Poland, until 18 years of age, a juvenile functions under the parental or tutelary authority, while a consent for medical service requires beside of the consent of legal guardian also the consent of a juvenile who is 16 years of age and becomes a full-right patient. According to the Act on Health Care Institutions, a patient has the right to self-decisions, the respect of physical and mental integrity and the respect of privacy, while the participation of a statutory representative post 16th year of age refers practically to co-deciding on a medical service provision. Therefore, the information received from such juvenile patient in subjective and objective examination does not have to be passed to the statutory representative, if the juvenile patient requires confidentiality and if this does not affect the patient's health and the planned medical procedures (e.g. the necessity of making an operation). The knowledge of conduct procedures with regard to a juvenile patient as a carrier of rights shall enable doctors to make aware choices of conduct and provide services or, in most cases, only advice, without the necessity to breach the laws of Poland.

Substance use and substance use disorders are highly prevalent among youth under juvenile justice (JJ) supervision, and related to delinquency, psychopathology, social problems, risky sex and sexually transmitted infections, and health problems. However, numerous gaps exist in the identification of behavioral health (BH) problems and in the subsequent referral, initiation and retention in treatment for youth in community justice settings. This reflects both organizational and systems factors, including coordination between justice and BH agencies. This paper presents a new framework, the Juvenile Justice Behavioral Health Services Cascade ("Cascade"), for measuring unmet substance use treatment needs to illustrate how the cascade approach can be useful in understanding service delivery issues and identifying strategies to improve treatment engagement and outcomes for youth under community JJ supervision. We discuss the organizational and systems barriers for linking delinquent youth to BH services, and explain how the Cascade can help understand and address these barriers. We provide a detailed description of the sequential steps and measures of the Cascade, and then offer an example of its application from the Juvenile Justice - Translational Research on Interventions for Adolescents in the Legal System project (JJ-TRIALS), a multi-site research cooperative funded by the National Institute on Drug Abuse. As illustrated with substance abuse treatment, the Cascade has potential for informing and guiding efforts to improve behavioral health service linkages for adolescent offenders, developing and testing interventions and policies to improve interagency and cross-systems coordination, and informing the development of measures and interventions for improving the implementation of treatment in complex multisystem service settings.

The mediating effect of parental neglect on adolescent and young adult anti-sociality: a longitudinal study of twins and their parents.

PubMed

Eaves, Lindon J; Prom, Elizabeth C; Silberg, Judy L

2010-07-01

The causes of correlation between parental treatment and offspring behavior are ambiguous since genetic and social factors are correlated in typical family studies. The problem is complicated by the need to characterize the effects of genes and environment on both juvenile and adult behavioral outcomes. A model is developed for the resemblance between juvenile and adult twins and their parents that allows some of these effects to be resolved. Data on childhood adversity, parental anti-social behavior, and longitudinal adult and juvenile anti-social behavior were obtained from 1,412 families of adolescent and young adult twins. A structural model is fitted that allows for the effects of genetic and social transmission of information from parents to children. Environmental effects of parents may be mediated through measured features of the home environment. Parameters were estimated by diagonal weighted least squares applied to the 33 distinct polychoric correlations between relatives and between variables within and between ages. Sub-hypotheses were tested. Results confirmed that effects of genes and environment were both highly significant. Genetic effects were large in juveniles and largely age and sex-specific. Approximately 30% of the variation due to the shared environment was due to the effect of childhood adversity. The remaining shared environmental effects are unexplained. Adversity is affected significantly by maternal anti-social behavior. The correlation between paternal ASP and adversity may be explained by antisocial fathers selecting (or creating) antisocial mothers. All significant environmental effects of parental ASP are mediated through the measure of adversity. Though transmission of ASP is both genetic and social, passive genotype-environment correlation is very small. Assortative mating for ASP has barely detectable consequence for the genetic correlation between siblings. The longitudinal study of twins and their parents makes it possible to demonstrate there is a direct causal effect of childhood adversity on child conduct disorder over and above any indirect genetic correlation.

Different Points of a Continuum? Cross Sectional Comparison of the Current and Pre-contact Psychosocial Problems among the Different Categories of Adolescents in Institutional Care in Nigeria

PubMed Central

2012-01-01

Background The combination of adverse social indicators and a predominantly youthful population puts Nigeria, and indeed many countries of sub-Sahara Africa, at the risk of explosion in the number of youth coming in contact with the juvenile justice system. Despite this risk, custodial childcare systems in the region are still poorly developed with both juvenile offenders and neglected adolescents coming in contact with the systems being kept in the same incarcerating facility. The needs of these different groups of adolescents may be different. Knowing their common and unique needs can inform common prevention strategies and ensure that specific service-needs of different categories of adolescents in institutional custody are met. Methods Data on the family background, pre-contact social circumstance, neurological and anthropometric profiles, and certain aspects of mental health of adolescents drawn from two juvenile justice institutions in Nigeria were obtained. The results for the adolescents on ‘criminal code’ and those admitted as a case of child neglect were compared using chi-square and odd ratios. Results Participants were 211 adolescents comprising of 158 on ‘criminal code’ and 53 declared as ‘neglected’. A lot of similarities were found. For instance, the prevalence of parental separation, family transition, experience of street-life and lifetime exposure to traumatic events and posttraumatic stress was equally high among the two groups of adolescents. The adolescents on ‘criminal code’ however had significantly higher prevalence of conduct and alcohol/substance use disorders while the child neglect group had poorer anthropometric profiles and higher prevalence of neurological disorders. Conclusions Child neglect and juvenile delinquency in Nigeria may truly be different points of a continuum. There are however fundamental differences that can warrant specific prevention strategies and tailor-made service provision while in custodial care. PMID:22835146

The Disease of the Italian Poet Giacomo Leopardi (1798-1837): A Case of Juvenile Ankylosing Spondylitis in the 19th Century?

PubMed

Sganzerla, Erik Pietro; Riva, Michele Augusto

2017-06-01

Some authors sustained that the pessimistic thought of the Italian writer and philosopher Giacomo Leopardi (1798-1837) may be attributed to his unhappy life, characterized by several health problems. His philosophical theories appear as the result of depressive and melancholic state, related to his precarious health conditions, so limiting their intrinsic values. Several authors formulated various hypotheses on the diseases that Leopardi suffered from and postulated different theories on the cause of his early death. This article assumed that Leopardi may have been affected by juvenile ankylosing spondylitis, conditioning spinal deformities, relapsing-remitting uveitis, urinary tract and bowel tract problems, and acute arthritis. Chest deformity, as a complication of juvenile ankylosing spondylitis, may have caused progressive cardiorespiratory failure, worsened by recurrent bronchial and pulmonary complications, until his death caused by acute right ventricular heart failure. The acknowledgment of a physical cause of Leopardi's disease contributes to reevaluate his "cosmic pessimism" as an original expression of his thought, so leading a general revaluation of the figure of one of the most important European thinkers of the 19th century.

This study draws on Conservation of Resources (COR) stress theory to examine the impact of a specific trauma, Hurricane Katrina, relative to other adverse life events on the mental health of female adolescent offenders in Mississippi. Teenage girls (N = 258, 69% African American) were recruited from 4 juvenile detention centers and the state training school. Participants were interviewed about the occurrence and timing of adverse life events and hurricane-related experiences and completed a self-administered mental health assessment. Hierarchical linear regression models were used to identify predictors of anxiety and depression. Pre-hurricane family stressors, pre-hurricane traumatic events, hurricane-related property damage, and receipt of hurricane-related financial assistance significantly predicted symptoms of anxiety and depression. Findings support COR theory. Family stressors had the greatest influence on symptoms of anxiety and depression, highlighting the need for family-based services that address the multiple, inter-related problems and challenges in the lives of female juvenile offenders.

Kopeĭko, G I

2011-01-01

The author analyzed the problem in historical, diagnostic and psychopathological aspects and presented the results of his own study. The aim was to study the structure and dynamics of endogenous juvenile mixed states in order to work out the psychopathological typology and to clarify the criteria of diagnosis, differential treatment and clinical-social prognosis. The study included 174 patients, 118 men and 56 women, aged from 17 to 25 years (mean age 20, 4 years). Depressive states were found in 65%, mania in 16% and mixed in 19% of patients. The clinical differentiation of mixed states was carried out basing on the dominating pole of affective disorders and the following types were singled out and described: mania type (dysphoria-like mania)--34%, depressive type (association-driven depression)--38%; alternating type of mixed states--28%. The preference of the formation of alternating and atypical variants of mixed states in the juvenile age demonstrated in the study may reflect the pathogenetic and pathoplastic effect of biological features characteristic of this age--lability and polymorphism of clinical presentations as well as immaturity of emotional and cognitive spheres.

Background Juvenile polyps are distinct hamartomatous malformations of the gastrointestinal tract that may occur in the heritable juvenile polyposis syndrome (JPS) or sporadically. Histologically, juvenile polyps are characterised by a marked increase of the stromal cell compartment but, an epithelial phenotype has also been reported. JPS has an increased risk of colorectal cancer but sporadic juvenile polyps do not. In 50–60% of JPS patients a germline mutation of the TGF-β/BMP pathway genes SMAD4 or BMPR1A is found. This study compares the histological phenotype of juvenile polyps with a SMAD4 or BMPR1A germline mutation and sporadic juvenile polyps. Methods H&E slides of 65 JPS polyps and 25 sporadic juvenile polyps were reviewed for histological features and dysplasia. Systematic random crypt and stroma counts were obtained by count stereology and a crypt-stroma ratio was determined. All polyps were subsequently categorised as type A (crypt-stroma ratio <1.00) or type B (crypt-stroma ratio ≥1.00), the latter referring to the epithelial phenotype. Cell cycle activity was assessed using immunohistochemistry of the proliferation marker Ki67, and mutation analysis was conducted for KRAS and APC to determine the involvement of the adenoma-carcinoma sequence. Results Juvenile polyps with a SMAD4 germline mutation were predominantly type B, whereas, type A was more common among juvenile polyps with a BMPR1A germline mutation, but this distinction could not be ascribed to differences in cell cycle activity. Dysplasia was equally common in JPS polyps with either a SMAD4 or BMPR1A germline mutation, where the involvement of the adenoma-carcinoma sequence does not seem to play a distinct role. Conclusion juvenile polyps in the setting of JPS exhibit distinct phenotypes correlating with the underlying genetic defect. PMID:21412070

A series of toxicity tests were conducted to investigate the role of chronological age on zinc tolerance in juvenile brown trout (Salmo trutta). Four different incubation temperatures were used to control the maturation of the juveniles before zinc exposures. These 96-h exposures used flow-through conditions and four chronological ages of fish with weights ranging from 0.148 to 1.432 g. Time-to-death (TTD) data were collected throughout the exposure along with the final mortality. The results indicate that chronological age does not play a predictable role in zinc tolerance for juvenile brown trout. However, a relationship between zinc tolerance and fish size was observed in all chronological age populations, which prompted us to conduct additional exploratory data analysis to quantify how much of an effect size had during this stage of development. The smallest fish (0.148-0.423 g) were shown to be less sensitive than the largest fish (0.639-1.432 g) with LC50 values of 868 and 354 µg Zn/L, respectively. The Kaplan-Meier product estimation method was used to determine survival functions from the TTD data and supports the LC50 results with a greater median TTD for smaller fish than larger juvenile fish. These results indicate that fish size or a related characteristic may be a significant determinant of susceptibility and should be considered in acute zinc toxicity tests with specific attention paid to the expected exposure scenario in the field.

Reference toxicant testing using juvenile freshwater mussels was conducted as part of the CR-ERP biomonitoring study of Clinch River sediments to assess the sensitivity of test organisms and the overall performance of the test. Tests were conducted using moderately hard synthetic water spiked with known concentrations of copper as copper sulfate. Two different foods, phytoplankton and YCT-Selenastrum (YCT-S), were tested in side by side tests to compare food quality. Toxicity testing of copper sulfate reference toxicant was conducted from July 6-15, 1993. The organisms used for testing were juvenile fresh-water mussels (Anodonta imbecillis). Results from this test showed LC{sub 50}more » values of 0.97 and 0.84 mg Cu/L for phytoplankton and YCT-S, respectively. Previously obtained values for phytoplankton tests are 2.02 and 1.12 mg Cu/L. Too few tests have been conducted with copper as the toxicant to determine a normal range of values. Although significant reduction in growth, compared to the phytoplankton control, was seen in all treatments, including the YCT-S Control, the consequence of this observation has not been established. Ninety-day testing of juvenile mussels exhibited large variations in growth within treatment and replicate groups.« less

Juvenile delinquency, welfare, justice and therapeutic interventions: a global perspective.

PubMed

Young, Susan; Greer, Ben; Church, Richard

2017-02-01

This review considers juvenile delinquency and justice from an international perspective. Youth crime is a growing concern. Many young offenders are also victims with complex needs, leading to a public health approach that requires a balance of welfare and justice models. However, around the world there are variable and inadequate legal frameworks and a lack of a specialist workforce. The UK and other high-income countries worldwide have established forensic child and adolescent psychiatry, a multifaceted discipline incorporating legal, psychiatric and developmental fields. Its adoption of an evidence-based therapeutic intervention philosophy has been associated with greater reductions in recidivism compared with punitive approaches prevalent in some countries worldwide, and it is therefore a superior approach to dealing with the problem of juvenile delinquency.

Psychopathology and personality in juvenile sexual homicide offenders.

PubMed

Myers, W C; Blashfield, R

1997-01-01

This project describes the psychopathology and personality findings in 14 juveniles who committed sexual homicide. These incarcerated youth were assessed using a structured interview, a personality assessment instrument, correctional files review, and an author-designed clinical interview. Nearly all of these youth met DSM-III-R conduct disorder criteria at the time of the crime. The presence of personality disorders and moderately high psychopathy scores at follow-up were common. Two-thirds of these youth reported the presence of violent sexual fantasies before their crimes. Weapons, most often knives, were used by these juvenile sexual murderers to kill known victims in a majority of the cases. They usually acted alone and selected a low risk victim. These findings suggest that juvenile sexual murderers are an emotionally and behaviorally disturbed population with identifiable psychopathology, personality disturbances, and criminal patterns.

We conducted a field experiment in SW Spain to test the efficacy of a myxomatosis vaccine, a viral disease strongly affecting wild rabbit populations, by assessing individual survival and antibody seroprevalence of monthly live-trapped, vaccinated (N=466) and unvaccinated (N=558) juvenile wild rabbits, between April and October 2007. Eight percent of all juveniles caught from April to June showed maternal antibodies against myxomatosis, whereas all animals were seropositive to the disease after the outbreak. Juveniles vaccinated before the outbreak showed 17% higher survival (31% vs. 14%) and an increased mortality probability of 8% after the outbreak. Results suggest that only a costly and systematic vaccination performed before the annual myxomatosis outbreak, would improve the survival of juvenile rabbits, a premise not always accomplished that compromises its efficacy in the field.

With the growing experience in the conduct of juvenile toxicity studies for multiple classes of compound, the 'case-by-case' approach has become under much more pressure. Instead, a general screen or 'standard design' is now commonly expected by regulatory authorities with more routine inclusion of neurological and reproductive assessments. Minor modifications or additions can be made to the design to address specific questions according to the class of drug or intended clinical use. This drift from a 'case-by-case' approach to a 'standard design' approach is present within certain reviewing divisions of the FDA, often requesting by default a rodent and non-rodent juvenile animal study. However, juvenile animal studies should be designed thoughtfully to fulfil a purpose based on scientific rationale, with each endpoint carefully considered in terms of practicality and interpretability of data generated. Only when using the appropriate strategy and design may juvenile studies add value by (1) identifying potential safety or pharmacokinetic issues for drugs intended for paediatric use, (2) suggesting additional clinical endpoints and (3) adding new information to the product label. As the knowledge from juvenile animal studies in various species grows, a better understanding of the significance/relevance of findings will be achieved.

Experimental manipulation reveals few subclinical impacts of a parasite community in juvenile kangaroos

Large mammalian herbivores are commonly infected with gastrointestinal helminths. In many host species, these helminths cause clinical disease and may trigger conspicuous mortality events. However, they may also have subclinical impacts, reducing fitness as well as causing complex changes to host growth patterns and body condition. Theoretically, juveniles should experience significantly greater costs from parasites, being immunologically naive and undergoing a significant growth phase. The aims of our study were to quantify the subclinical effects of helminths in juvenile eastern grey kangaroos (Macropus giganteus), which commonly harbour large burdens of gastrointestinal nematodes and are susceptible to associated mass mortality during cold, wet conditions. We conducted a field experiment on a population of free-ranging kangaroos, removing nematodes from one group of juveniles using an anthelmintic treatment. We then compared growth parameters (body condition and growth rates) and haematological parameters of this group with an age-matched, parasitised (untreated) control group. Treated juvenile kangaroos had significantly higher levels of plasma protein (albumin) but, contrary to our predictions, showed negligible changes in all the other parameters measured. Our results suggest that juvenile kangaroos are largely unaffected by their gastrointestinal helminth burdens, and may be able to compensate for the costs of parasites. PMID:25161906

Background: There is an intimate relationship between drugs and criminal behavior. The drug–violence relationship is further complicated by intoxicating doses and/or withdrawal effects of specific drugs. Understanding this relationship is important for both healthcare workers and policy makers. Materials and Methods: The study was conducted in Prayas observation home for boys, a short stay home for juveniles-under-enquiry in New Delhi. The present study aims to correlate substance use and criminal behavior by investigating the sociodemographic characteristics and the current trend of substance use among juveniles in New Delhi. In this study, 487 detained juveniles aged between 8 and 18 years were included. The information was obtained by face-to-face semi-structured interviews and juvenile case records maintained by the juvenile home. Results: Out of 487 juveniles-under-enquiry booked under different crimes, 86.44% of the sample had a history of substance use. Consumption of tobacco and cannabis were higher when compared to other drugs. Consumption of psychotropic drugs though relatively lesser was related with more serious crimes. There is an increasing trend in serious crimes such as rape, murder/attempt to murder, and burglary committed by juveniles. Drug-crime correlation has been noted among consumption of cannabis with murder, inhalants with rape and opioids with snatching-related crimes. Conclusion: Substance use and criminal behavior are clearly interrelated. Greater the involvement in substance abuse, more severe is the violence and criminality. This paper highlights this complex relationship and suggests possible scope of interventions. PMID:27385851

In this study I tested Benson Ginsburg's theory that dogs should show diminished ability, compared to wolves, in orienting in three-dimensional space and manipulating objects sequentially. Dogs of all ages and juvenile wolves should do poorly on these measures, but at some time before sexual maturity, the juvenile wolves should begin improving to the level of adult wolves. Two adult and seven juvenile wolves were compared with 40 adult German shepherds. The initial task was to pull a single rope suspended from the ceiling; complexity was increased by the addition of ropes and by changing spatial configurations. Adult wolf performance was consistently successful across all tests and requirements. Juvenile wolves had little difficulty with one and two rope tests, but did more poorly in the three rope tests. The behavior of the dogs grouped into four profiles (# of dogs): non-responders (6), one rope (15), two rope (14), and three rope responders (5).

Responding to urgent calls for effective interventions to address young offenders' multiple and interconnected problems, a new variant of an existing empirically-validated intervention for drug-using adolescents, Multidimensional Family Therapy (MDFT)-Detention to Community (DTC) was tested in a two-site controlled trial. This article (a) outlines the rationale and protocol basics of the MDFT-DTC intervention, a program for substance-using juvenile offenders that links justice and substance abuse treatment systems to facilitate adolescents' post-detention community reintegration; (b) presents implementation outcomes, including fidelity, treatment engagement and retention rates, amount of services received, treatment satisfaction, and substance abuse-juvenile justice system collaboration outcomes; and (c) details the implementation and sustainability challenges in a cross-system (substance abuse treatment and juvenile justice) adolescent intervention. Findings support the effectiveness of the MDFT-DTC intervention, and the need to develop a full implementation model in which transfer and dissemination issues could be explored more fully, and tested experimentally.

Background Currently, there is a lack of clear guidelines regarding evaluation and management of giant juvenile fibroadenomas. The purpose of this study was to conduct a systematic review of giant juvenile fibroadenomas and to evaluate the most common diagnostic and therapeutic modalities. Methods A systematic literature search of PubMed and MEDLINE databases was conducted in February 2014 to identify articles related to giant juvenile fibroadenomas. Pooled outcomes are reported. Results Fifty-two articles (153 patients) met inclusion criteria. Mean age was 16.7 years old, with a mean lesion size of 11.2 cm. Most patients (86%) presented with a single breast mass. Imaging modalities included ultrasound in 72.5% and mammography in 26.1% of cases. Tissue diagnosis was obtained using a core needle biopsy in 18.3% of cases, fine-needle aspiration (FNA) in 25.5%, and excisional biopsy in 11.1% of patients. Surgical treatment was implemented in 98.7% of patients (mean time to treatment of 9.5 months, range, 3 days to 7 years). Surgical intervention included excision in all cases, of which four were mastectomies. Breast reconstruction was completed in 17.6% of cases. There were no postoperative complications. Conclusions Diagnosis and treatment of giant juvenile fibroadenoma is heterogeneous. There is a paucity of data to support observation and non-operative treatment. The most common diagnostic modalities include core needle or excisional biopsy. The mainstay of treatment is complete excision with an emphasis on preserving the developing breast parenchyma and nipple areolar complex. Breast reconstruction is uncommon, but may be necessary in certain cases. PMID:26312217

2016-01-01

Cigarette use is a prominent problem in juvenile offenders, leading to negative health outcomes and substance use. One interesting precipitator of cigarette use in this population is discrimination. Social support could potentially buffer the positive relationship between cigarette use and discrimination in juvenile offenders, which could be dependent on the context in which the discrimination is experienced, such as peer, institutional (e.g., stores, restaurants), or educational contexts. The present study explored the relationship between three types of discrimination, social support, and smoking outcomes among 112 detained and probated juvenile offenders (mean age = 16.24, SD = 2.11, 29.2% female, 54.9% Caucasian, 40.4% detention, 53.8% smokers). Results indicated that the relationship between institutional discrimination (OR = −0.10, p = 0.005) and peer discrimination (OR = −0.11, p = 0.01) were significantly moderated by social support, with a higher likelihood of being a smoker, compared to a non-smoker at higher levels of peer and institutional discrimination. Further, based on a moderated regression analysis, results indicated that youth who experienced greater educational discrimination and lower levels of social support, they were at higher risk of nicotine addiction (b = −0.09, p = 0.03). Overall, results indicate that varying avenues of social support, such as parent, peer, and teacher support, can mitigate negative effects of discrimination on juvenile offenders, particularly cigarette use. Addressing discrimination in smoking treatment and prevention in juvenile offenders may be of great utility. Future studies should examine the potential mechanisms underlying the discrimination and cigarette use connection in juvenile offenders. PMID:27010849

2013-01-01

This study reports the prevalence of emotional and behavioral problems among youths placed in juvenile correctional facilities in Jordan and describes the effect of length of stay on mental health outcomes. The Youth Self Report (YSR) was administered to 187 adolescent males (mean age=16.4, SD=1.0) in all five juvenile detention facilities in Jordan in 2011. Descriptive statistics were calculated to estimate the prevalence of emotional and behavioral problems. Logistic regression models were estimated to evaluate the impact of placement length on mental health. Statistical models were weighted by the youth propensity to be 'long-stay' youths (>23 weeks) based on preplacement case characteristics. The prevalence of clinically significant emotional and behavioral problems was 84%. 46% had YSR scores above the clinical cutpoint in both the internalizing and externalizing subscales. 24% of youths reported suicidal ideation. The high prevalence of emotional and behavioral disorders was stable across placement for most YSR subscales. The prevalence of emotional and behavioral disorders among detained and incarcerated youth in Jordan mirrors the literature worldwide. These findings suggest that serious mental health problems for many youths persist throughout placement. Copyright © 2013 Elsevier Ltd. All rights reserved.

Uncoupling protein and ATP/ADP carrier increase mitochondrial proton conductance after cold adaptation of king penguins.

Juvenile king penguins develop adaptive thermogenesis after repeated immersion in cold water. However, the mechanisms of such metabolic adaptation in birds are unknown, as they lack brown adipose tissue and uncoupling protein-1 (UCP1), which mediate adaptive non-shivering thermogenesis in mammals. We used three different groups of juvenile king penguins to investigate the mitochondrial basis of avian adaptive thermogenesis in vitro. Skeletal muscle mitochondria isolated from penguins that had never been immersed in cold water showed no superoxide-stimulated proton conductance, indicating no functional avian UCP. Skeletal muscle mitochondria from penguins that had been either experimentally immersed or naturally adapted to cold water did possess functional avian UCP, demonstrated by a superoxide-stimulated, GDP-inhibitable proton conductance across their inner membrane. This was associated with a markedly greater abundance of avian UCP mRNA. In the presence (but not the absence) of fatty acids, these mitochondria also showed a greater adenine nucleotide translocase-catalysed proton conductance than those from never-immersed penguins. This was due to an increase in the amount of adenine nucleotide translocase. Therefore, adaptive thermogenesis in juvenile king penguins is linked to two separate mechanisms of uncoupling of oxidative phosphorylation in skeletal muscle mitochondria: increased proton transport activity of avian UCP (dependent on superoxide and inhibited by GDP) and increased proton transport activity of the adenine nucleotide translocase (dependent on fatty acids and inhibited by carboxyatractylate).

Ruperto, Nicolino; Vesely, Richard; Saint-Raymond, Agnes; Martini, Alberto

2013-12-01

Conducting clinical trials in paediatric rheumatology has been difficult mainly because of the lack of funding for academic studies and the lack of interest by pharmaceutical companies in the small and non-rewarding paediatric market. The situation changed dramatically a few years ago with the introduction of the Best Pharmaceuticals for Children Act in the USA and of specific legislation for the development of paediatric medicines (Paediatric Regulation) in the European Union (EU). The EU Paediatric Regulation had a positive impact in paediatric rheumatology-in particular, on the development of new treatments for children with juvenile idiopathic arthritis (JIA). Some problems remain, however, such as greater harmonisation of the regulatory aspects of medicines, how to handle me-too agents, how to conduct adequate pharmacokinetic studies and develop age-appropriate formulations, ethical problems in study review and implementation, and a change in the current JIA classification. The introduction of specific legislation, coupled with the existence of large international networks such as the Pediatric Rheumatology Collaborative Study Group (PRCSG at http://www.prcsg.org), covering North America, and the Paediatric Rheumatology International Trials Organisation (PRINTO at http://www.printo.it), covering more than 50 countries, has led to great advances in paediatric rheumatology. Future changes might increase the possibility of conducting trials with similar approaches in other paediatric rheumatological conditions and provide evidence-based treatments for children affected by rheumatic diseases.

Curfew laws have been instituted in cities across the United States in an attempt to control the rise in juvenile crime. This article discusses the advantages and disadvantages of a curfew law for Baltimore City based on interviews with city officals and concludes that the law in its present form will not bring about any significant change in the rate of delinquency. Alternative are suggested that might better get to the source of the problem. These include more youth and family counseling services, rehabilitative facilities, work study programs and shelter areas.

Glaucoma in juvenile xanthogranuloma.

Juvenile xanthogranuloma (JXG) is a benign histiocytic skin disorder mainly encountered during infancy. Approximately 10% of cases exhibit ocular manifestations leading to serious complications. Specifically, secondary glaucoma can result in severe and blinding eye disease. We present a case of a two-month-old female with JXG related glaucoma in order to demonstrate the classic presentation and the problems commonly encountered in treating this disease. The natural history, pathogenesis, and treatment of the condition are then discussed and the pertinent literature reviewed. JXG should be considered in any case of unilateral glaucoma that presents in infancy.

There is a large proportion of minority youth involved in the juvenile justice system. Disproportionate minority contact (DMC) occurs when the proportion of any ethnic group is higher at any given stage in the juvenile justice process than the proportion of this group in the general population. There are several theories explaining the presence and persistence of DMC. This article reviews the history of DMC and the theories and implications of this problem. It discusses several targets for interventions designed to reduce DMC and offer resources in this area. Copyright © 2016 Elsevier Inc. All rights reserved.

2016-01-01

High morbidity of mental disorders among juvenile offenders has been confirmed by several studies, thus challenging both the juvenile justice system and the mental health system. Data from developed countries may not reflect the situation in low-income countries and therefore cannot form a basis for intervention. No similar study has been done in Sudan. The objective to determine prevalence of psychiatric disorders among incarcerated youth in Al-Juref juvenile correctional facility. All juveniles (forty eight) were studied utilizing a descriptive cross-sectional study design. Data was collected using a socio-demographic questionnaire and the MINI-KID 6.0 and was analyzed using the SPSS v.20. Most respondents were males (Forty six) with a mean age of fifteen (±1.6 years SD). Most were living with both parents (75%) and were school dropouts (41.7%). The majority was arrested for theft (33.3%) and rape (29.2%). Prevalence of psychiatric disorders was high (60.4%) with conduct disorder (CD) being the most common (47.9%), followed by anxiety disorders (31.1%) and major depressive disorder (14.6%). Comorbid psychiatric disorders rate was high (31%). Even after subtracting CD, prevalence was still common (39%). New information can help mental health providers and policy makers in the juvenile justice system make effective interventions in provision of mental health services. We recommend clinical assessment for juveniles when they appear at court and training of workers in the justice system on how to detect features of psychopathology. PMID:28096556

DNA fingerprint similarity between female and juvenile brown-headed cowbirds trapped together

Hahn, D.C.; Fleischer, R.C.

1995-01-01

This DNA fingerprinting study investigates whether females of the brood parasite brown-headed cowbird, Molothrus ater, associate with their own juvenile offspring at feeding sites more often than would be expected by chance. Cowbirds lay their eggs in the nests of a variety of host species and, as far as is known, leave them to the care of foster parents. Using baited walk-in funnel traps, 36 adult female-juvenile pairs (or trios) of cowbirds were trapped. Blood samples were collected from these individuals to conduct DNA fingerprinting analyses, calculate similarity indices, and to compare S-values for the 11 comparisons of juveniles and the females with which they were caught with S-values of random pairings of juveniles and the females in adjacent gel lanes with which they were not caught. Overall band-sharing was significantly higher for the individuals trapped together than for the random pairings. These associations between juvenile cowbirds and their mothers could occur as a result of female cowbirds monitoring the development of their young in the nests where they have laid. Alternatively, nestling cowbirds in the nest could become familiar visually and locally with a female parent that is frequently in their territory and could follow her when she departs for feeding grounds. In either case these data suggest that adult cowbirds associate with juveniles, in some cases their own offspring, and that offspring may learn to function as cowbirds in part from this association.

Justice-involved youth endorse high rates of mental health problems. Juvenile probation is the most common disposition in the justice system and juvenile probation officers (JPOs) are crucial for connecting justice-involved youth with appropriate care. We examined the role of mental health competency on the use of self-report case management strategy types (deterrence, restorative justice, and treatment) by JPOs and whether jurisdiction-level differences were relevant. Results suggest that mental health competency predicted use of restorative justice and treatment strategies and all three strategy types varied at the county level. The role of mental health competency in use of treatment strategies is relevant to connecting justice-involved youth to mental health care. Furthermore, a substantial amount of the variance predicting the use of all three strategies was accounted for at the county level.

Kin assortment in juvenile shoals in wild guppy populations.

2011-05-01

Grouping provides many potential benefits to individuals in terms of foraging and anti-predator protection. However, it has been suggested that individuals could gain additional benefits in terms of indirect fitness by grouping with kin. Surprisingly, the genetic composition of wild fish shoals and the importance of kin-associated shoaling remain poorly understood. The Trinidadian guppy (Poecilia reticulata) has life history traits that might promote kin structure of shoals such as internal fertilisation and small brood size in contrast to many other fish species. Even though previous studies did not find any indication of kin structure in shoals of adult guppies, it is possible that related juveniles remain together in shoals, partly because of lower mobility and because the advantages of kin association may change with age. Using 10 microsatellite markers, we conducted a genetic analysis on 40 shoals from four populations. Pair-wise relatedness was inferred using a modified version of the software package COLONY and permutation tests were conducted to test the hypothesis that kin occur together in juvenile shoals more often than expected by chance. The frequency of sib dyads among juveniles within shoals was significantly larger than that between shoals in two high predation populations but not in two low predation populations. This finding contributes to the understanding of factors underlying shoal composition and highlights the potential of recent methodological advances for detecting such relationships.

Juvenile justice, delinquency, and psychiatry.

PubMed

Steiner, H; Cauffman, E

1998-07-01

Juvenile delinquency is a serious problem in the United States, and is likely to remain so for many years to come. Because delinquency often is accompanied by high rates of coincidental and causal comorbidities, effective treatment programs for CD youths must use multimodal approaches tailored to each youth's particular set of psychopathologies. Child psychiatrists are uniquely qualified to provide assistance and leadership in the treatment of delinquent youths, as their problems are best captured by a developmental psychopathology model. Knowledge regarding the epidemiology of CD, and of the risk factors associated with it, is excellent, although a thorough understanding of resilience and treatment is still developing. Successful involvement in the treatment of delinquent youth requires that psychiatrists maintain a diverse set of skills, a high level of flexibility in treatment approaches, and a special awareness of the legal parameters governing the rehabilitation of these youngsters.

Collateral Consequences of Juvenile Sex Offender Registration and Notification: Results From a Survey of Treatment Providers.

Harris, Andrew J; Walfield, Scott M; Shields, Ryan T; Letourneau, Elizabeth J

2016-12-01

Among many in the research, policy, and practice communities, the application of sex offender registration and notification (SORN) to juveniles who sexually offend (JSO) has raised ongoing concerns regarding the potential collateral impacts on youths' social, mental health, and academic adjustment. To date, however, no published research has systematically examined these types of collateral consequences of juvenile SORN. Based on a survey of a national sample of treatment providers in the United States, this study investigates the perceived impact of registration and notification on JSO across five key domains: mental health, harassment and unfair treatment, school problems, living instability, and risk of reoffending. Results indicate that treatment providers overwhelmingly perceive negative consequences associated with registration with an incremental effect of notification indicating even greater concern across all five domains. Providers' demographics, treatment modalities, and client profile did not influence their perceptions of the collateral consequences suggesting that provider concern about the potential harm of SORN applied to juveniles is robust. Policy implications are discussed. © The Author(s) 2015.

A 24-year-old Japanese woman developed anterocollis, weakness of the proximal arms, and subsequent cognitive impairment. A neurological examination revealed amyotrophic lateral sclerosis (ALS) without a family history. Systemic muscle atrophy progressed rapidly. Cerebral MRI clearly exhibited high signal intensities along the bilateral pyramidal tracts. An analysis of the FUS gene revealed a heterozygous two-base pair deletion, c.1507-1508delAG (p.G504WfsX515). A subset of juvenile-onset familial/sporadic ALS cases with FUS gene mutations reportedly demonstrates mental retardation or learning difficulty. Our study emphasizes the importance of conducting a FUS gene analysis in juvenile-onset ALS cases, even when no family occurrence is confirmed.

Finding paradise: cues directing the migration of the waterfall climbing Hawaiian gobioid Sicyopterus stimpsoni.

2012-07-01

A series of waterfall-climbing trials were conducted to identify cues that direct the climbing of juvenile Sicyopterus stimpsoni. In the first experiment, whether climbing juveniles preferentially ascend water sources with conspecifics or whether the presence of just stream water is sufficient to attract fish to ascend a climbing path were assessed. In the second experiment, whether climbing juveniles create a trail of mucus that facilitates the ability of conspecifics to follow their lead was determined. The results indicate that juvenile S. stimpsoni are less likely to climb in waters devoid of organic cues but are strongly attracted to stream water with or without the odour of conspecifics. Once climbing, performance did not differ for juveniles climbing in differing water choices, suggesting an all-or-nothing commitment once climbing commences. Climbing S. stimpsoni did produce a mucous trail while climbing that was associated with a mucous gland that dramatically increases in size just prior to juveniles gaining the ability to climb. The trail was not followed closely by subsequent juveniles traversing the same channel, however, suggesting only weak trail-following in waterfall climbing S. stimpsoni. Previous genetic studies suggest that juvenile S. stimpsoni do not home to natal streams in the face of strong near-shore oceanic currents. Instead, these fish appear primarily to rely on cues that suggest the presence of organic growth in streams, a factor that may indicate suitable habitat in an ever-changing stream environment but which may also be vulnerable to interference through human activity. © 2012 The Authors.

Use of stress-hormone levels and habitat selection to assess functional connectivity of a landscape for an amphibian.

2012-10-01

The influence of landscape matrix on functional connectivity has been clearly established. Now methods to assess the effects of different land uses on species' movements are needed because current methods are often biased. The use of physiological parameters as indicators of the level of resistance to animal movement associated with different land uses (i.e., matrix resistance) could provide estimates of energetic costs and risks to animals migrating through the matrix. To assess whether corticosterone levels indicate matrix resistance, we conducted experiments on substrate choice and measured levels of corticosterone before and after exposure of toads (Bufo bufo) to 3 common substrates (ploughed soil, meadow, and forest litter). We expected matrix resistance and hormone levels to increase from forest litter (habitat of the toad) to meadows to ploughed soil. Adult toads had higher corticosterone levels on ploughed soil than on forest litter or meadow substrates. Hormone levels did not differ between forest litter and meadow. Toads avoided moving onto ploughed soil. Corticosterone levels in juvenile toads were not related to substrate type; however, hormone levels decreased as humidity increased. Juveniles, unlike adults, did not avoid moving over ploughed soil. The difference in responses between adult and juvenile toads may have been due to differences in experimental design (for juveniles, entire body used to measure corticosterone concentration; for adults, saliva alone); differences in the scale of sensory perception of the substrate (juveniles are much smaller than adults); or differences in cognitive processes between adult and juvenile toads. Adults probably had experience with different substrate types, whereas juveniles first emerging from the water probably did not. As a consequence, arable lands could act as ecological traps for juvenile toads. ©2012 Society for Conservation Biology.

Common Snook Centropomus undecimalis were once abundant off the Texas coast, but these populations are now characterized by low abundance and erratic recruitment. Most research concerning Common Snook in North America has been conducted in Florida and very little is known about the specific biology and habitat needs of Common Snook in Texas. The primary objective of this study was to describe the habitat use patterns of juvenile Common Snook and their role in the fish assemblage in the lower portion of the Rio Grande, Texas. Secondarily, we documented the relationship between age and juvenile reproductive development. Fish were collected during January–March 2006 from the lower 51.5 km of the Rio Grande using a bottom trawl and boat-mounted electrofisher. Measurements of water quality and other habitat traits were recorded at each sampling site. We captured 225 Common Snook exclusively in freshwater habitats above river kilometer 12.9. The distribution of juvenile Common Snook was not random, but influenced primarily by turbidity and dissolved oxygen. Sex differentiation and gonadal development based on histological examination of gonads established that age-1 and age-2 Common Snook were juvenile, prepubertal males. There was no difference between the age groups in their overall distribution in the river. However, age-2 Common Snook were associated with deeper areas with faster currents, higher conductivity, and steeper banks. Overall, Common Snook in the lower Rio Grande show substantial differences in habitat use than their counterparts in other parts of the range of the species, but it is unclear whether this is due to differences in habitat availability, behavioral plasticity, or some combination thereof.

In order to study the effect of concentrates restriction on feed consumption, diet digestibility, and utilization of nitrogen in captive Asian elephants (Elephas maximus), two feeding trials were conducted on three juveniles, four sub-adults, and three adults. During trial I, the conventional zoo diets of juveniles, sub-adults, and adult contained 22, 17, and 16% of concentrates on dry matter (DM) basis, respectively. During trial II, the amount of concentrate was reduced by 50%. A digestion trial of five days collection period was conducted during each period. The animals ate more roughages when concentrates were restricted. Intake of DM (g/kg BW(0.75) /day) was highest in sub-adults, followed by juveniles and adults. Apparent digestibility of crude protein (CP), neutral detergent soluble (NDS), and supply of digestible energy (DE) was highest in juveniles, followed by sub-adults and adults. Based upon the estimated metabolic fecal nitrogen (MFN) and calculated endogenous urinary nitrogen (EUN) and dermal losses, minimum dietary CP required to meet maintenance requirement was estimated to be 6.12, 6.05, and 5.97% in juveniles, sub-adults, and adults, respectively. Restriction of concentrates resulted in decreased (P < 0.05) digestibility of DM and GE, but the diet still supplied adequate amounts of DE and CP to fulfill estimated requirements of energy and protein during the period of experimentation. Thus, the concentrates portion of the diets of captive Asian elephants should be fed in a restricted way so as to reduce the intake of excessive calories and the potential risk of obesity. © 2014 Wiley Periodicals, Inc.

Vulnerability to predation and physiological stress responses of experimentally descaled juvenile Chinook salmon, Oncorhynchus tshawytscha

Juvenile salmonids,Oncorhynchus spp., commonly encounter conditions (e.g., during hatchery release and dam passage) that result in damage to the skin, scale, and slime complex. We conducted laboratory experiments to determine if descaling of juvenile chinook salmon,O. tshawytscha, increased their vulnerability to predation, and to assess the physiological stress responses elicited by descaling. Salmon were experimentally descaled on either 10% or 20% of their total body area. When offered equal numbers of control and descaled juvenile chinook salmon, northern squawfish,Ptychocheilus oregonensis, did not consume significantly more of either prey type (48–60% of consumed prey were descaled). Juvenile chinook salmon descaled on 10% of their body area did show significant physiological stress responses, however. Mean concentrations of plasma cortisol peaked 1 h after descaling, and returned to control levels by 12 h. Plasma glucose peaked 3 h post-treatment and remained elevated for 24 h. Plasma lactate increased immediately following treatment and returned to undisturbed control levels by 3 h. The osmoregulatory response of plasma potassium was highly variable, but plasma sodium decreased immediately and remained low for 24 h. The observed physiological responses suggest that descaling of juvenile chinook salmon could result in decreased resistance to disease and other stressors encountered in the field, possibly leading to reduced performance capacity and lowered survival.

We conducted a series of in situ tests to evaluate the effects of pore-water ammonia on juvenile Lampsilis cardium in the St. Croix River (WI, USA). Threats to this river and its associated unionid fauna have accelerated in recent years because of its proximity to Minneapolis-St. Paul, Minnesota, USA. In 2000, caged juveniles were exposed to sediments and overlying water at 12 sites for 10 d. Survival and growth of juveniles was significantly different between sediment (mean, 47%) and water column (mean, 86%) exposures; however, these effects were unrelated to pore-water ammonia. During 2001, juveniles were exposed to sediments for 4, 10, and 28 d. Pore-water ammonia concentrations ranged from 0.3 to 62.0 ??g NH3-NIL in sediments and from 0.5 to 140.8 ??g NH3-N/L within exposure chambers. Survival (mean, 45, 28, and 41% at 4, 10, and 28 d, respectively) and growth (range, 3-45 ??,m/d) of juveniles were highly variable and generally unrelated to ammonia concentrations. Although laboratory studies have shown unionids to be quite sensitive to ammonia, further research is needed to identify the route(s) of ammonia exposure in unionids and to understand the factors that contribute to the spatial variability of ammonia in rivers.

Juvenile king penguins develop adaptive thermogenesis after repeated immersion in cold water. However, the mechanisms of such metabolic adaptation in birds are unknown, as they lack brown adipose tissue and uncoupling protein-1 (UCP1), which mediate adaptive non-shivering thermogenesis in mammals. We used three different groups of juvenile king penguins to investigate the mitochondrial basis of avian adaptive thermogenesis in vitro. Skeletal muscle mitochondria isolated from penguins that had never been immersed in cold water showed no superoxide-stimulated proton conductance, indicating no functional avian UCP. Skeletal muscle mitochondria from penguins that had been either experimentally immersed or naturally adapted to cold water did possess functional avian UCP, demonstrated by a superoxide-stimulated, GDP-inhibitable proton conductance across their inner membrane. This was associated with a markedly greater abundance of avian UCP mRNA. In the presence (but not the absence) of fatty acids, these mitochondria also showed a greater adenine nucleotide translocase-catalysed proton conductance than those from never-immersed penguins. This was due to an increase in the amount of adenine nucleotide translocase. Therefore, adaptive thermogenesis in juvenile king penguins is linked to two separate mechanisms of uncoupling of oxidative phosphorylation in skeletal muscle mitochondria: increased proton transport activity of avian UCP (dependent on superoxide and inhibited by GDP) and increased proton transport activity of the adenine nucleotide translocase (dependent on fatty acids and inhibited by carboxyatractylate).

Juvenile Fibromyalgia Syndrome (JFMS) is a chronic health condition characterized by widespread musculoskeletal pain and multiple tender points (TP). The objective of this study was to determine the prevalence of JFMS in the urban population of Samsun and to determine the impact of JFMS on depression symptoms, school performance and quality of life (QOL). A cross-sectional study was conducted in 1109 children (mean age (14.8 ± 2.0) years old). A questionnaire was applied to the children and a medical examination including TP was performed. Yunus and Masi's criteria were used for diagnosis of JFMS. The children with JFMS were compared with an age and sex matched non-JFMS group. Depression was assessed with Children's Depression Inventory (CDI) and QOL was evaluated with Pediatric Quality of Life Inventory 4.0 (PedsQL4.0). Sixty-one (5.5%) (13 boys and 48 girls) of 1109 children met the diagnostic criteria of JFMS. While PedsQL scores of children with JFMS were lower than the non-JFMS group for physical, emotional, social, school functioning and total score (P = 0.001), CDI total score was higher in the JFMS group than in the non-JFMS group (P = 0.001). The JFMS group reported more school absences (P = 0.001) and the average school grade was lower in the JFMS group than in the non-JFMS group (P = 0.03). The prevalence of JFMS is high in school age children. Since JFMS is a common problem of childhood, early diagnosis and identification of the disorder and more comprehensive and successful treatment approaches with appropriate psychological assistance may prevent more complex and severe problems in adulthood.

Juvenile delinquency is a serious and common problem. To date, several studies have focused on possible psychosocial risk factors for delinquency among youths and on the implications of childhood mental illness on child criminality. However, the literature on prevalence of psychopathology and predictors of crime severity among delinquent youths in Turkey is sparse. Therefore, the aim of this study was to show the associations between crime severity and psychosocial factors such as gender, age, criminal history, concomitant attention deficit hyperactivity disorder (ADHD) and other comorbid psychiatric conditions, along with behavioral problem domains of Child Behavior Checklist (CBCL). This analytical cross-sectional study sample consisted of 52 individuals (30 females and 22 males) who were sent to a pilot detention facility in Istanbul, Turkey. The participants' age ranged from 8 to 18 years ( M =13.4; SD =2.9). Self-rating scales were administered in an interview format, and the crime severity information was provided by participants' admission documents. No differences were found in terms of gender, age, children's past history of crime and substance abuse. However, family crime history was significantly higher in the high severity crime group ( P =0.026). Having one or more comorbid psychiatric disorder was associated with high crime severity ( P =0.018). The most common psychiatric disorders were found to be ADHD, oppositional defiant disorder, conduct disorder (CD) and anxiety disorder. Findings suggest that a family history of crime comes across as a very strong predictor of severity of crime. Among psychiatric factors, ADHD and CD were associated with commitment of more severe crimes in delinquent youths in our sample. Anxious/depressed traits as depicted by CBCL are found to be associated with less severe crimes.

Purpose Juvenile delinquency is a serious and common problem. To date, several studies have focused on possible psychosocial risk factors for delinquency among youths and on the implications of childhood mental illness on child criminality. However, the literature on prevalence of psychopathology and predictors of crime severity among delinquent youths in Turkey is sparse. Therefore, the aim of this study was to show the associations between crime severity and psychosocial factors such as gender, age, criminal history, concomitant attention deficit hyperactivity disorder (ADHD) and other comorbid psychiatric conditions, along with behavioral problem domains of Child Behavior Checklist (CBCL). Participants and methods This analytical cross-sectional study sample consisted of 52 individuals (30 females and 22 males) who were sent to a pilot detention facility in Istanbul, Turkey. The participants’ age ranged from 8 to 18 years (M =13.4; SD =2.9). Self-rating scales were administered in an interview format, and the crime severity information was provided by participants’ admission documents. Results No differences were found in terms of gender, age, children’s past history of crime and substance abuse. However, family crime history was significantly higher in the high severity crime group (P=0.026). Having one or more comorbid psychiatric disorder was associated with high crime severity (P=0.018).

2017-11-01

The U.S. Department of Justice has called for the creation of trauma-informed juvenile justice systems in order to combat the negative impact of trauma on youth offenders and frontline staff. Definitions of trauma-informed care have been proposed for various service systems, yet there is not currently a widely accepted definition for juvenile justice. The current systematic review examined published definitions of a trauma-informed juvenile justice system in an effort to identify the most commonly named core elements and specific interventions or policies. A systematic literature search was conducted in 10 databases to identify publications that defined trauma-informed care or recommended specific practices or policies for the juvenile justice system. We reviewed 950 unique records, of which 10 met criteria for inclusion. The 10 publications included 71 different recommended interventions or policies that reflected 10 core domains of trauma-informed practice. We found 8 specific practice or policy recommendations with relative consensus, including staff training on trauma and trauma-specific treatment, while most recommendations were included in 2 or less definitions. The extant literature offers relative consensus around the core domains of a trauma-informed juvenile justice system, but much less agreement on the specific practices and policies. A logical next step is a review of the empirical research to determine which practices or policies produce positive impacts on outcomes for youth, staff, and the broader agency environment, which will help refine the core definitional elements that comprise a unified theory of trauma-informed practice for juvenile justice.

Objective We validated the Myositis Damage Index (MDI) in juvenile and adult myositis, to describe the degree and types of damage and to develop predictors of damage. Methods Retrospective MDI evaluations and prospective assessment of disease activity and illness features were conducted. Juvenile-onset patients (n = 143) were evaluated a median of 18 months after diagnosis; 135 patients were assessed 7–9 months later, and 121 were last assessed 82 months after diagnosis. Adult-onset patients (n = 96) with dermatomyositis (DM) or polymyositis (PM) had a baseline assessment a median of 30 months after diagnosis; 77 had a 6-month follow-up evaluation, and 55 had a final assessment 60 months after diagnosis. Results Damage was present in 79% of juvenile and 97% of adult patients. In juveniles, scar, contractures, persistent weakness, muscle dysfunction and calcinosis (23–30%) were most frequent on last evaluation. In adults, muscle atrophy, muscle dysfunction and weakness were most frequent (74–84%). MDI severity correlated with physician global damage, functional disability, weakness and muscle atrophy on MRI. MDI damage scores and frequency were highest in patients with a chronic illness course and in adult patients who died. Predictors of damage included functional disability, active disease duration, onset severity, global activity, and illness features, including ulcerations in children and pericarditis in adults. Conclusions Damage is common in myositis patients after a median of 5 years duration in adult-onset and 6.8 years in juvenile-onset patients. The MDI has good content, construct and predictive validity in juvenile and adult myositis. PMID:19877055

Tributyltin (TBT) is as an antifouling organotin compound used in boat paints. Although organotin-based antifouling agents have been banned on a global scale, the mode of action of TBT has been studied in numerous aquatic species because of its toxicity, persistence, bioaccumulation potential, and endocrine-disrupting characteristics. In this study, we conducted 96-h acute toxicity tests wherein we exposed juvenile and adult marine mysids to waterborne TBT. Over 4 weeks of exposure, mortality was dose-dependently increased in juveniles and adult mysids. To test sublethal effects of TBT on juvenile development, newborn juvenile mysids were exposed to 1, 5, or 10 ng L -1  TBT for 4 weeks. Subsequently, we measured morphological growth parameters and quantified the hormone ecdysterone (20-hydroxyecdysone: 20E), which controls molting in mysids. The lengths of the whole body, antennal scale, exopod, endopod, and telson were significantly smaller in the 5 and/or 10 ng L -1 TBT-exposed juvenile mysids than in control and DMSO-exposed groups. Levels of 20E were significantly lower at 5 and 10 ng L -1  TBT exposures. Additionally, the number of newly hatched juveniles was significantly lower from females previously exposed to 10 ng L -1  TBT. Our results indicate sublethal concentrations of TBT have inhibitory effects on the survival, growth, and production of juveniles. The lower 20E levels could be strongly associated with TBT-triggered inhibition. Copyright © 2018 Elsevier Ltd. All rights reserved.

2015-03-04

In The Netherlands, police officers not only come into contact with juvenile offenders, but also with a large number of juveniles who were involved in a criminal offense, but not in the role of a suspect (i.e., juvenile non-offenders). Until now, no valid and reliable instrument was available that can be used by Dutch police officers for estimating the risk for future care needs of juvenile non-offenders. In the present study, the Youth Actuarial Care Needs Assessment Tool for Non-Offenders (Y-ACNAT-NO) was developed for predicting the risk for future care needs that consisted of (1) a future supervision order as imposed by a juvenile court judge and (2) future worrisome incidents involving child abuse, domestic violence/strife, and/or sexual offensive behavior at the juvenile's living address (i.e., problems in the child-rearing environment). Police records of 3,200 juveniles were retrieved from the Dutch police registration system after which the sample was randomly split in a construction (n = 1,549) and validation sample (n = 1,651). The Y-ACNAT-NO was developed by performing an Exhaustive CHAID analysis using the construction sample. The predictive validity of the instrument was examined in the validation sample by calculating several performance indicators that assess discrimination and calibration. The CHAID output yielded an instrument that consisted of six variables and eleven different risk groups. The risk for future care needs ranged from 0.06 in the lowest risk group to 0.83 in the highest risk group. The AUC value in the validation sample was .764 (95% CI [.743, .784]) and Sander's calibration score indicated an average assessment error of 3.74% in risk estimates per risk category. The Y-ACNAT-NO is the first instrument that can be used by Dutch police officers for estimating the risk for future care needs of juvenile non-offenders. The predictive validity of the Y-ACNAT-NO in terms of discrimination and calibration was sufficient to justify its use as an initial screening instrument when a decision is needed about referring a juvenile for further assessment of care needs.

Mansion, Andre D; Chassin, Laurie

2016-02-01

The high rates of substance disorders in the juvenile justice system, as well as the relation between substance use and reoffending, suggest the importance of substance use treatment service and understanding the factors that influence treatment provision. The current study tested whether race/ethnicity affects the relation between substance use disorder diagnosis and the receipt of substance use treatment services among a sample of male serious juvenile offenders (N=638). Findings showed that among adolescents with a substance use disorder diagnosis, there were no race/ethnicity differences in substance use treatment receipt. However, among adolescents without a substance use disorder diagnosis, non-Hispanic Caucasians were more likely to receive substance use treatment than were Hispanics or African-Americans. Additionally, findings showed that there were race/ethnicity differences in service receipt at moderate levels of substance use problems, such that non-Hispanic Caucasians were more likely to receive substance use treatment than Hispanics or African-Americans. There were no race/ethnicity differences in treatment receipt when substance use problems were either very severe or very low. Results suggest that race/ethnicity may play a role in service provision in the juvenile justice system when levels of need are less clear.

2012-06-01

Adult psychopathy has proven to be an important clinical and forensic construct, but much less is known about juvenile psychopathy. In the present study, we examined the construct validity of the self report modified Child Psychopathy Scale mCPS; Lynam (Psychological Bulletin 120:(2), 209-234, 1997) in a sample of 57 adolescents residing in a Dutch juvenile justice center, aged between 13 and 22 years. The mCPS total score was reliably related to high externalizing problems, low empathy, high anger and aggression, high impulsivity, high (violent) delinquency, and high alcohol/drug use. Unique relations were found for the antisocial-impulsive (mCPS Factor 2), but not the callous-unemotional facet of psychopathy (mCPS Factor 1). Our findings support the validity of the mCPS in that it encompasses the antisocial-impulsive facet of psychopathy, but it is less clear whether the mCPS sufficiently captures the affective-interpersonal facet of psychopathy.

Patterns of Competence and Adjustment Among Adolescents from Authoritative, Authoritarian, Indulgent, and Neglectful Homes: A Replication in a Sample of Serious Juvenile Offenders

2009-01-01

The correlates of authoritative, authoritarian, indulgent, and neglectful parenting were examined within a sample of 1,355 14- to 18-year-olds adjudicated of serious criminal offenses. The sample is composed primarily of poor, ethnic-minority youth living in impoverished urban neighborhoods. As has been found in community samples, juvenile offenders who describe their parents as authoritative are more psychosocially mature, more academically competent, less prone to internalized distress, and less prone to externalizing problems than their peers,whereas those who describe their parents as neglectful are less mature, less competent, and more troubled. Juvenile offenders who characterize their parents as either authoritarian or indulgent typically score somewhere between the two extremes, although those from authoritarian homes are consistently better functioning than those from indulgent homes. These patterns did not vary as a function of adolescents' ethnicity or gender. PMID:20016759

Preventing and treating obesity in pediatrics through physical activity.

PubMed

Graf, Christine

2011-09-01

The prevalence of juvenile obesity is increasing worldwide. Throughout Europe, ca. 20% are affected, in Germany 15%. Many modifiable and nonmodifiable causes have been determined and included, but are not limited to genetic, familiar, and lifestyle factors. In addition, obesity disproportionately affects minority and low socioeconomic status groups. Juvenile obesity increases the risk of having multiple cardiovascular and metabolic diseases, psycho-social problems, and a variety of other co-morbidities. The burden upon the health services cannot yet be estimated. Therefore, there is a need for preventive and therapeutic counter-measures. Until now, most approaches focus on changing the behaviour of individuals in diet and exercise. Based on the existing data researchers agree that programmes should start as early as possible and involve children's environment (family, peers etc.). In conclusion, a positive public health approach including political, environmental, sociocultural, and educational strategies offer the best chance of preventing and reducing juvenile obesity.

Displacement and suicide risk for juvenile justice-involved youth with mental health issues.

Kretschmar, Jeff M; Flannery, Daniel J

2011-01-01

This article examined the relationship between suicide behaviors and displacement, as defined by out-of-home placement, in a sample of juvenile-justice-involved youth with mental health issues. Participants included boys and girls between the ages of 10 and 18 who were enrolled in a juvenile justice diversion program for children with mental or behavioral health problems. Data collected included youth-reported suicide and self-harm ideation, caregiver reports of previous suicide attempts, and whether the youth had been in an out-of-home placement in the year prior to enrollment in the program. Logistic regression analyses indicated that youth who had recently been in an out-of-home placement reported significantly less suicide ideation and marginally less self-harm ideation than youth who had not been in an out-of-home placement. Out-of-home placement status had no impact on caregiver reports of previous youth suicide attempts.

Juvenile offenders with substance use problems are at high risk for deleterious long-term outcomes. This study evaluated the capacity of a promising vocational and employment training program in the building sector (i.e., Community Restitution Apprenticeship-Focused Training, CRAFT) to mitigate such outcomes through enhanced employment and education. Participants were 97 high-risk juvenile offenders (mean age = 15.8 years) randomized to CRAFT versus education as usual (EAU) intervention conditions. Multi-method procedures measured employment, education, substance use, mental health, and criminal outcomes through a 30-month post-baseline follow-up. CRAFT was significantly more effective than EAU at increasing rates of youth employment and GED attendance. Intervention effects were not observed, however, for months employed, hours worked, or hourly wage. Measures of youth substance use, mental health symptoms, and criminal activity showed no favorable or iatrogenic effects. The potential of CRAFT was modestly supported, and suggestions were made for future research. PMID:23958035

Mental illness, violence risk, and race in juvenile detention: implications for disproportionate minority contact.

PubMed

Desai, Rani A; Falzer, Paul R; Chapman, John; Borum, Randy

2012-01-01

Disproportionate minority contact (DMC) is a pervasive problem throughout the juvenile justice system. This article explored whether mental illness may be an explanatory factor in DMC. Data such as measures of violence risk and symptoms of mental illness were taken from intake interviews with 482 detained youth in Connecticut. Results indicated that racial minorities in detention have significantly lower violence risk than Caucasians but are disproportionately represented among detention populations relative to their proportions in the general population. In addition, DMC in these data was not explained by mental illness, seriousness of charges, violence risk, age, or gender. We suggest that mandated efforts to reduce DMC will need to address more than improving behavior or reducing symptoms of mental illness among detained minority youth. Instead, efforts should be focused on reducing the racial disparity evident in decisions made within the juvenile justice system. © 2012 American Orthopsychiatric Association.

Peer violence, peer sexual harassment and abuse, and staff abuse experienced by boys and girls in juvenile correctional facilities are compared with those experienced by peers in schools in the community. Responses of 360 youths in 20 gender-separated correctional facilities in Israel to a questionnaire tapping these forms of mistreatment were compared with those of 7,012 students in a representative sample of Israeli junior high and high schools. Victimization was reported more frequently by those in correctional facilities than by those in schools. However, some of the more prevalent forms of violence and abuse were reported with equal frequency in both settings, and some more frequently in schools. Despite being victimized more frequently, those in the correctional facilities tended to view their victimization as a significantly less serious problem than those in the schools and to rate the staff as doing a better job of dealing with the problem.

Genetic conflict between sexual signalling and juvenile survival in the three-spined stickleback.

PubMed

Kim, Sin-Yeon; Velando, Alberto

2016-02-29

Secondary sexual traits and mating preferences may evolve in part because the offspring of attractive males inherit attractiveness and other genetically correlated traits such as fecundity and viability. A problem regarding these indirect genetic mechanisms is how sufficient genetic variation in the traits subject to sexual selection is maintained within a population. Here we explored the additive genetic correlations between carotenoid-based male ornament colouration, female fecundity and juvenile survival rate in the three-spined stickleback (Gasterosteus aculeatus) to test the possibility that attractiveness genes reduce important fitness components in the bearers not expressing the sexual trait. Male sexual attractiveness (i.e., red nuptial colouration) as well as female fecundity and juvenile viability showed heritable variations in the three-spined stickleback. Thus, females can gain indirect benefits by mating with an attractive male. There was a strong positive genetic correlation between female fecundity and juvenile viability. However, red sexual signal of male sticklebacks was negatively genetically correlated with juvenile survival, suggesting genetic conflict between attractiveness and viability. There was no significant correlation between attractiveness of brothers and fecundity of sisters, suggesting no intra-locus sexual conflict. The negative effects of mating with a colourful male on offspring viability may contribute to maintaining the heritable variation under strong directional sexual selection. The strength of indirect sexual selection may be weaker than previously thought due to the hidden genetic conflicts.

Identification, Characterization, and Mapping of a Novel SNP Associated with Body Color Transparency in Juvenile Red Sea Bream (Pagrus major).

2018-03-23

We previously reported a body color deformity in juvenile red sea bream, which shows transparency in the juvenile stage because of delayed chromatophore development compared with normal individuals, and this finding suggested a genetic cause based on parentage assessments. To conduct marker-assisted selection to eliminate broodstock inheriting the causative gene, developing DNA markers associated with the phenotype was needed. We first conducted SNP mining based on AFLP analysis using bulked-DNA from normal and transparent individuals. One SNP was identified from a transparent-specific AFLP fragment, which significantly associated with transparent individuals. Two alleles (A/G) were observed in this locus, and the genotype G/G was dominantly observed in the transparent groups (97.1%) collected from several production lots produced from different broodstock populations. A few normal individuals inherited the G/G genotype (5.0%), but the A/A and A/G genotypes were dominantly observed in the normal groups. The homologs region of the SNP was searched using a medaka genome database, and intron 12 of the Nell2a gene (located on chromosome 6 of the medaka genome) was highly matched. We also mapped the red sea bream Nell2a gene on the previously developed linkage maps, and this gene was mapped on a male linkage group, LG4-M. The newly found SNP was useful in eliminating broodstock possessing the causative gene of the body color transparency observed in juvenile stage of red sea bream.

Sex and race differences in mental health symptoms in juvenile justice: the MAYSI-2 national meta-analysis.

Vincent, Gina M; Grisso, Thomas; Terry, Anna; Banks, Steven

2008-03-01

Studies have suggested a high prevalence of mental health symptoms among youths in the juvenile justice system, with the highest prevalence among girls and whites compared to boys and other races. This multisite, archival study examined whether sex and race differences, when they exist, were consistent across U.S. juvenile justice programs. Data included scores on the Massachusetts Youth Screening Instrument-Version 2 (MAYSI-2) for 70,423 youths from 283 juvenile justice probation, detention, or corrections programs. A meta-analytic technique investigated the consistency of effect sizes for sex and race/ethnic differences across sites in self-reported mental health problems; Across sites, girls on average were 1.8 (95% confidence interval 0.98-1.10) to 2.4 (95% confidence interval 2.38-2.48) times as likely as boys to have clinical elevations on all applicable MAYSI-2 scales except the Alcohol/Drug Use scale. On the Alcohol/Drug Use scale, a sex effect existed but only among youngeryouths. Whites were more likely to have clinical elevations than blacks or Hispanics; but surprisingly disparities varied across mental health categories and varied considerably across sites. At the aggregate level, 72% of girls and 63% of boys had a clinical elevation on at least one MAYSI-2 scale. Our meta-analytic technique indicated that the sex differences across sites were even larger than these numbers imply. Conversely and counter to existing evidence, race-related differences were generally small or nonexistent. Whites were more likely to have alcohol and drug problems and suicide ideation, but not more likely to have symptoms of depression, anxiety, or thought disturbance than blacks or Hispanics.

Photosynthesis in developing leaf of juveniles and adults of three Mediterranean species with different growth forms.

PubMed

Chondrogiannis, Christos; Grammatikopoulos, George

2016-12-01

Leaf development is influenced by almost all the prevailing environmental conditions as well as from the conditions at the time of bud formation. Furthermore, the growth form of a plant determines the leaf longevity and subsequently the investment in biomass and the internal structure of the mesophyll. Therefore, photosynthetic traits of a growing leaf, though, partly predetermined, should also acclimate to temporal changes during developmental period. In addition, the age of the plant can affect photosynthesis of the growing leaf, yet, in the majority of studies, the age is associated to the size of the plant. To test if the reproductive status of the plant affects the time kinetics of the photosynthetic capacity of a growing leaf and the relative contribution of the plants' growth form to the whole procedure, field measurements were conducted in juveniles (prereproductive individuals) and adults (fully reproductive individuals) of an evergreen sclerophyllous shrub (Nerium oleander), a semi-deciduous dimorphic shrub (Phlomis fruticosa), and a winter deciduous tree with pre-leafing flowering (Cercis siliquastrum). PSII structural and functional integrity was progressively developed in all species, but already completed, only some days after leaf expansion in P. fruticosa. Developing leaf as well as fully developed leaf in adults of C. siliquastrum showed enhanced relative size of the pool of final PSI electron acceptors. Photosynthetic traits between juveniles and adults of P. fruticosa were similar, though the matured leaf of adults exhibited lower transpiration rates and improved water-use efficiency than that of juveniles. Adults of the evergreen shrub attained higher CO 2 assimilation rate than juveniles in matured leaf which can be attributed to higher electron flow devoted to carboxylation, and lower photorespiration rate. The reproductive phase of the plant seemed to be involved in modifications of the PSII and PSI functions of the deciduous tree, in carboxylation and photorespiration traits of the evergreen shrub, and in water conductance efficiency of the semi-deciduous shrub. However, it is interesting, that regardless of the growth form of the plant and the prospective leaf longevity of the developing leaf, adults need to support flowering outmatch juveniles, in terms of photosynthesis.

Youth with juvenile justice histories often reside in poorly resourced communities and report high rates of depression, gang involved networks, and STI-sexual related risk behaviors, compared to their counterparts. The primary aim of this study was to examine the relationship between social context (ie, a combined index score comprised of living in public housing, being a recipient of free school lunch, and witnessing community violence) and risk factors that are disproportionately worse for juvenile justice youth such as depression, gang involved networks and STI sexual risk behaviors. Data were collected from a sample of detained youth ages 14 to 16 (N = 489). Questions assessed demographics, social context, depression, gang-involved networks, and STI risk behaviors. Multiple logistic regression models, controlling for age, gender, race, school enrollment, and family social support, indicated that participants who reported poorer social context had double the odds of reporting being depressed; three times higher odds of being in a gang; three times higher odds of personally knowing a gang member; and double the odds of having engaged in STI-risk behaviors. These results provide significant information that can help service providers target certain profiles of youth with juvenile justice histories for early intervention initiatives.

Juvenile Rhus glabra leaves have higher temperatures and lower gas exchange rates than mature leaves when compared in the field during periods of high irradiance.

We sought to test the hypothesis that stomatal development determines the timing of gas exchange competency, which then influences leaf temperature through transpirationally driven leaf cooling. To test this idea, daily patterns of gas exchange and leaflet temperature were obtained from leaves of two distinctively different developmental stages of smooth sumac (Rhus glabra) grown in its native habitat. Juvenile and mature leaves were also sampled for ultrastructural studies of stomatal development. When plants were sampled in May-June, the hypothesis was supported: juvenile leaflets were (for part of the day) from 1.4 to 6.0 degrees C warmer than mature leaflets and as much as 2.0 degrees C above ambient air temperature with lower stomatal conductance and photosynthetic rates than mature leaflets. When measurements were taken from July to October, no significant differences were observed, although mature leaflet gas exchange rates declined to the levels of the juvenile leaves. The gas exchange data were supported by the observations that juvenile leaves had approximately half the number of functional stomata on a leaf surface area basis as did mature leaves. It was concluded that leaf temperature and stage of leaf development in sumac are strongly linked with the higher surface temperatures observed in juvenile leaflets in the early spring possibly being involved in promoting photosynthesis and leaf expansion when air temperatures are cooler.

The toxicity of dietary exposure to artificially aged TiO₂ nanomaterial (T-Lite) used in sunscreen cream was studied on Danio rerio. Embryolarval assays were conducted to assess the effects of TiO₂ residues of nanomaterial (RNM) on fish early life stages. Juvenile fishes were exposed by the trophic route in two experiments. During the first experiment, juvenile fishes were exposed to TiO₂ RNM for 14 days by adding RNM to commercial fish food. The second one consisted in producing a trophic food chain. Pseudokirchneriella subcapitata algae, previously contaminated with TiO₂ RNM in growth medium, was used to feed Daphnia magna neonates over a 48-h period. Daphnia were used next to feed juvenile fishes for 7 days. Accumulation of Ti, life traits (survival and growth) and biochemical parameters such as energy reserves, digestive (trypsin, esterase, cellulose and amylase) and antioxidant (superoxide dismutase and catalase) enzyme activity were measured at the end of exposures. As expected in the receiving aquatic system, TiO2 RNM at low concentrations caused a low impact on juvenile zebrafish. A slight impact on the early life stage of zebrafish with premature hatching was observed, and this effect appeared mainly indirect, due to possible embryo hypoxia. When juvenile fish are exposed to contaminated food, digestive enzyme activity indicated a negative effect of TiO₂ RNM. Digestive physiology was altered after 14 days of exposure and seemed to be an indirect target of TiO₂ RNM when provided by food.

Laboratory bioassays were conducted to evaluate the effects of six vineyard pesticides on Typhlodromus pyri Scheuten (Acari: Phytoseiidae), a key predator of the mite Calepitrimerus vitis Nalepa (Acari: Eriophyoidae), in Pacific coastal vineyards. Materials tested were whey powder, 25% boscalid + 13% pyraclostrobin (Pristine), 40% myclobutanil (Rally), micronized sulfur (92% WP), 75% ethylene bisdithiocarbamate (mancozeb; Manzate), and 91.2% paraffinic oil (JMS Stylet), all applied at three concentrations. Pesticide dilutions were directly sprayed onto T. pyri adult females and juveniles, and each treatment was assessed to determine effects on direct mortality and fecundity. Five of the six pesticides tested resulted in < 50% mortality to adult and juvenile T. pyri for all concentrations 7 d after treatment. Paraffinic oil treatments displayed direct mortality > 50% for adult and juvenile assays and resulted in significantly higher mortality. Sublethal effects were more pronounced than acute pesticide toxicity, particularly in juvenile mite bioassays. Significant decreases in fecundity were detected in the sulfur and mancozeb treatments compared with the control in juvenile tests. The relative percentage of fecundity reduction for juvenile mites was highest when applying mancozeb (> 70%), sulfur (> 25%), or myclobutanil (> 20%). Adult mites displayed the greatest reductions in fecundity from applications of paraffinic oil (> 20%) or mancozeb (> 15%) treatments. Boscalid (+ pyraclostrobin) and whey displayed the least effect on fecundity across all bioassays. These results can be used to develop management guidelines in vineyard pest management practices to help conserve and enhance predatory mite populations.

To estimate the parameters that govern mass- and temperature-dependent growth, we conducted a meta-analysis of existing growth data from juvenile Chinook Salmon Oncorhynchus tshawytscha that were fed an ad libitum ration of a pelleted diet. Although the growth of juvenile Chinook Salmon has been well studied, research has focused on a single population, a narrow range of fish sizes, or a narrow range of temperatures. Therefore, we incorporated the Ratkowsky model for temperature-dependent growth into an allometric growth model; this model was then fitted to growth data from 11 data sources representing nine populations of juvenile Chinook Salmon. The model fit the growth data well, explaining 98% of the variation in final mass. The estimated allometric mass exponent (b) was 0.338 (SE = 0.025), similar to estimates reported for other salmonids. This estimate of b will be particularly useful for estimating mass-standardized growth rates of juvenile Chinook Salmon. In addition, the lower thermal limit, optimal temperature, and upper thermal limit for growth were estimated to be 1.8°C (SE = 0.63°C), 19.0°C (SE = 0.27°C), and 24.9°C (SE = 0.02°C), respectively. By taking a meta-analytical approach, we were able to provide a growth model that is applicable across populations of juvenile Chinook Salmon receiving an ad libitum ration of a pelleted diet.

We examined the effect of high salinity wastewater (brine) from oil and natural gas drilling on freshwater mussels in the Allegheny River, Pennsylvania, during 2012. Mussel cages (N = 5 per site) were deployed at two sites upstream and four sites downstream of a brine treatment facility on the Allegheny River. Each cage contained 20 juvenile northern riffleshell mussels Epioblasma torulosa rangiana). Continuous specific conductance and temperature data were recorded by water quality probes deployed at each site. To measure the amount of mixing throughout the entire study area, specific conductance surveys were completed two times during low-flow conditions along transects from bank to bank that targeted upstream (reference) reaches, a municipal wastewater treatment plant discharge upstream of the brine-facility discharge, the brine facility, and downstream reaches. Specific conductance data indicated that high specific conductance water from the brine facility (4,000–12,000 µS/cm; mean 7,846) compared to the reference reach (103–188 µS/cm; mean 151) is carried along the left descending bank of the river and that dilution of the discharge via mixing does not occur until 0.5 mi (805 m) downstream. Juvenile northern riffleshell mussel survival was severely impaired within the high specific conductance zone (2 and 34% at and downstream of the brine facility, respectively) and at the municipal wastewater treatment plant (21%) compared to background (84%). We surveyed native mussels (family Unionidae) at 10 transects: 3 upstream, 3 within, and 4 downstream of the high specific conductance zone. Unionid mussel abundance and diversity were lower for all transects within and downstream of the high conductivity zone compared to upstream. The results of this study clearly demonstrate in situ toxicity to juvenile northern riffleshell mussels, a federally endangered species, and to the native unionid mussel assemblage located downstream of a brine discharge to the Allegheny River.

We conducted a radiotelemetry evaluation to determine if strobe lights could be used to decrease turbine entrainment of juvenile steelhead (Oncorhynchus mykiss) at Cowlitz Falls Dam, Washington. We found that radio-tagged juvenile steelhead approached and entered two spillbays (one lighted, one unlighted) in equal proportions. However, the presence of strobe lights was associated with decreased spillbay residence time of juvenile steelhead and increased passage through induction slots (secondary turbine intakes located upstream of the ogee on the spillway). Mean residence time of tagged fish inside the lighted spillbay was 14 min compared to 62 min inside the unlighted spillbay. Radio-tagged steelhead passed through induction slots at a higher proportion in the lighted spillbay (55%) than in the unlighted spillbay (26%). Recent studies have suggested that strobe lights can induce torpor in juvenile salmonids. We believe that strobe light exposure affected fish in our study at a location where they were susceptible to high flows thereby reducing mean residence time and increasing the proportion of tagged fish entering induction slots in the lighted spillbay. Our results suggest that factors such as deployment location, exposure, and flow are important variables that should be considered when evaluating strobe lights as a potential fish-deterring management tool.

Biopsychosocial Causes of Suicide and Suicide Prevention Outcome Studies in Juvenile Detention Facilities: A Review.

2017-03-01

To identify various biopsychosocial risk factors associated with suicidality in juvenile detention facilities and the effectiveness of suicide prevention protocols currently in use. Medical literature searches were conducted using databases like Pub Med, Ovid, and Google Scholar to identify studies conducted in and outside of United States. The prevalence of suicide among youth imprisoned at detention facilities has risen. Psychiatric disorders are common among such population, making them vulnerable to suicidal tendencies. Suicide risk screening within first 24 h of admission to the detention facility has shown to lower the risk of suicide. Identification of high risk individuals and their further psychiatric assessment is advocated. Much of work with regards to screening tools and instruments is underway and further study is required to get a better understanding.

To investigate relationships among family risk factors, childhood firesetting and animal cruelty, and adolescent delinquency. In 1990, mothers and children participating in a 10-year prospective study provided information about family risk factors and childhood problem behavior. Subsequent interviews with 86% of the sample in 1996 and 1998 and court record reviews in 2000 provided information about juvenile delinquency. Marital violence (odds ratio [OR] 2.4, 95% confidence interval [CI] = 1.1-5.4), paternal pet abuse (OR 2.4, CI = 1.0-5.6), and paternal drinking (r = 0.14) were related to firesetting, whereas exposure to marital violence (OR 2.3, CI = 1.0-5.1) and paternal (r = 0.19) and maternal harsh parenting (r = 0.14) were associated with animal cruelty. Regression analyses indicated that after controlling for conduct disorder, firesetters were 3.0 times (CI = 1.3-6.7) at risk of juvenile court referral and 3.3 times (CI = 1.4-7.6) at risk of arrest for a violent crime. Analysis of self-reports of delinquency replicated these results. Animal cruelty was related to self-reported violent crime (beta = 0.16). These findings indicate that family variables increase the likelihood of childhood firesetting and animal cruelty and that these behaviors are related to adolescent delinquency.

Little is known about the three-dimensional depth distributions in rivers of individually marked fish that are in close proximity to hydropower facilities. Knowledge of the depth distributions of fish approaching dams can be used to understand how vulnerable fish are to injuries such as barotrauma as they pass through dams. To predict the possibility of barotrauma injury caused by pressure changes during turbine passage, it is necessary to understand fish behaviour relative to acclimation depth in dam forebays as they approach turbines. A guiding study was conducted using high-resolution three-dimensional tracking results of salmonids implanted with Juvenile Salmon Acoustic Telemetry System transmitters to investigate the depth distributions of subyearling and yearling Chinook salmon (Oncorhynchus tshawytscha) and juvenile steelhead (Oncorhynchus mykiss) passing two dams on the Snake River in Washington State. Multiple approaches were evaluated to describe the depth at which fish were acclimated, and statistical analyses were performed on large data sets extracted from ∼28 000 individually tagged fish during 2012 and 2013. Our study identified patterns of depth distributions of juvenile salmonids in forebays prior to passage through turbines or juvenile bypass systems. This research indicates that the median depth at which juvenile salmonids approached turbines ranged from 2.8 to 12.2 m, with the depths varying by species/life history, year, location (which dam) and diel period (between day and night). One of the most enlightening findings was the difference in dam passage associated with the diel period. The amount of time that turbine-passed fish spent in the immediate forebay prior to entering the powerhouse was much lower during the night than during the day. This research will allow scientists to understand turbine-passage survival better and enable them to assess more accurately the effects of dam passage on juvenile salmon survival.

Habitat choice by juvenile cod ( Gadus morhua L.) on sandy soft bottoms with different vegetation types

Habitat choice by juvenile cod ( Gadus morhua L.) on sandy bottoms with different vegetation types was studied in laboratory. The experiment was conducted day and night in flow-through tanks on two different size-classes of cod (7-13 and 17-28 cm TL). Four habitats, typical of shallow soft bottoms on the Swedish west coast: Fucus vesiculosus, Zostera marina, Cladophora sp. and bare sand, were set up pair-wise in six combinations. The main difference between habitats in this study was vegetation structure, since all parameters except vegetation type was considered equal for both sides of the experimental tanks and natural prey was eliminated. The results showed a difference in habitat utilization by juvenile cod between day (light) and night (dark). During day time the fishes showed a significant preference for vegetation, while nocturnally no significant choice of habitat was made. Both size-classes preferred Fucus, considered the most complex habitat in this study, when this was available. The smaller size-class seemed to be able to utilize the other vegetation types as well, always preferring vegetation over sand. Larger juvenile cod, on the other hand, appeared to be restricted to Fucus. This difference in habitat choice by the two size-classes might be due to a greater dependence on shelter from predation by the smaller juveniles, causing them to associate more strongly with vegetation. The larger juveniles avoided Cladophora, since they might have difficulties in entering the compact structure of this filamentous algae. Availability of vegetation at day time, as a predation refuge, as well as of open sandy areas for feeding during night, thus seems to be important for juvenile cod. It is concluded that eutrophication-induced changes in habitat structure, such as increased dominance by filamentous algae, could alter the availability of predation refuges and foraging habitats for juvenile cod.

We sought to understand incarcerated youths' perspectives on the role of protective factors and risk factors for juvenile offending. We performed an in-depth qualitative analysis of interviews (conducted October-December 2013) with 20 incarcerated youths detained in the largest juvenile hall in Los Angeles. The adolescent participants described their homes, schools, and neighborhoods as chaotic and unsafe. They expressed a need for love and attention, discipline and control, and role models and perspective. Youths perceived that when home or school failed to meet these needs, they spent more time on the streets, leading to incarceration. They contrasted the path through school with the path to jail, reporting that the path to jail felt easier. All of them expressed the insight that they had made bad decisions and that the more difficult path was not only better but also still potentially achievable. Breaking cycles of juvenile incarceration will require that the public health community partner with legislators, educators, community leaders, and youths to determine how to make success, rather than incarceration, the easier path for disadvantaged adolescents.

Evaluation of several chemical disinfectants for removing zebra mussels from unionid mussels

We evaluated the safety and effectiveness of chemical treatments for killing veliger and juvenile stages of the zebra mussel Dreissena polymorpha attached to unionid mussels. Static toxicity tests were conducted on eight unionid mussel species with common aquaculture chemicals (benzalkonium chloride, formalin, hydrogen peroxide, calcium chloride, potassium chloride, and sodium chloride). The concentration and duration of each chemical treatment tested had previously been found to kill zebra mussel veligers and juveniles. Several species (e.g., Elliptio dilatata, Lampsilis cardium, and Lasmigona complanata) incurred less than 10% mortality in chloride salt treatments, while in other species (e.g., Obliquaria reflexa and Leptodea fragilis) mortality varied greatly among treatment regimes. Treatments with benzalkonium chloride, formalin, and hydrogen peroxide were less than 90% effective on juvenile stages of zebra mussels and, therefore, were ruled out after preliminary trials. Limited application of specific chemical treatments may be feasible for more tolerant species; however, effective disinfection of unionid shells will require the use of chemical treatment followed by a quarantine period to completely remove zebra mussel larvae and juveniles.

Although bocaccio (Sebastes paucispinis) was an economically important rockfish species along the west coast of North America, overfishing has reduced the stock to about 7.4% of its former unfished population. In 2003, using a manned research submersible, we conducted fish surveys around eight oil and gas platforms off southern California as part of an assessment of the potential value of these structures as fish habitat. From these surveys, we estimated that there was a minimum of 430,000 juvenile bocaccio at these eight structures. We determined this number to be about 20% of the average number of juvenile bocaccio that survive annually for the geographic range of the species. When these juveniles become adults, they will contribute about one percent (0.8%) of the additional amount of fish needed to rebuild the Pacific Coast population. By comparison, juvenile bocaccio recruitment to nearshore natural nursery grounds, as determined through regional scuba surveys, was low in the same year. This research demonstrates that a relatively small amount of artificial nursery habitat may be quite valuable in rebuilding an overfished species.

2016-04-01

Juvenile crime is a serious public health problem that results in significant emotional and financial costs for victims and society. Using etiologic models as a guide, multiple interventions have been developed to target risk factors thought to perpetuate the emergence and persistence of delinquent behavior. Evidence suggests that the most effective interventions tend to have well-defined treatment protocols, focus on therapeutic approaches as opposed to external control techniques, and use multimodal cognitive-behavioral treatment strategies. Moving forward, there is a need to develop effective policies and procedures that promote the widespread adoption of evidence-based delinquency prevention practices across multiple settings.

Some quantitative indicators of postovulatory aging and its effect on larval and juvenile development of Atlantic salmon (Salmo salar).

PubMed

Mommens, Maren; Storset, Arne; Babiak, Igor

2015-07-01

Modern out-of-season egg production in Atlantic salmon (Salmo salar) increases the risk of postovulatory aging (POA) of oocytes. Postovulatory aging is known to influence oocyte quality in salmonids, but reliable tests for POA are lacking in Atlantic salmon egg production. To address this problem, we have collected oocytes from the same 20 Atlantic salmon females sequentially in approximately 1-week intervals, from the start of ovulation until 28 days postovulation (dpo), to determine the effect of natural retention of matured oocytes in body coelomic cavity on further performance of embryos and juveniles produced from those oocytes. Also, we investigated oocyte water hardening and several coelomic fluid parameters as potential quantitative indicators of POA. Oocyte quality decreased significantly from 22 dpo onward, as inferred from decrease in fertilization success and survival of embryos, alevins, and juveniles and increase in alevin and juvenile deformity rates. The occurrence of head deformities was significantly related to postovulatory age of oocytes. Coelomic fluid pH decreased significantly at 28 dpo and correlated positively with fertilization rates (r = 0.45), normal eyed embryo rates (r = 0.67), and alevin relative survival rates (r = 0.63) and negatively correlated with total alevin deformity rates (r = -0.59). Oocyte weight gain at 60 minutes decreased significantly at 28 dpo and correlated negatively with total alevin deformities and the occurrence of cranial nodules (r = -0.99). Generally, quality of ovulated oocytes remained stable for the first 2 weeks after ovulation. Later on, POA negatively influenced Atlantic salmon embryo, alevin, and juvenile performance. For the first time, we show a long-term effect of POA on salmonid juvenile performance. Standardized pH measurements of coelomic fluid could potentially improve embryo and juvenile production by identifying low-quality oocytes at an early stage during the production.

This study explored expectations and experiences of employment among young people with juvenile idiopathic arthritis and the role of health professionals in promoting positive employment outcomes. Semistructured interviews (n = 13) and three focus groups (n = 9, n = 4, n = 3) were conducted with young people (16-25 y) and adults (26-31 y) with juvenile idiopathic arthritis and semistructured interviews (n = 9) were conducted with health professionals. Transcripts were analyzed thematically. Young people with juvenile idiopathic arthritis have concerns about employers' attitudes toward employees with long-term health conditions and lack knowledge of antidiscrimination legislation. Young people not in education, employment or training identify arthritis as a key barrier. Challenges associated with arthritis (e.g., pain, psychological distress) may not be visible to employers. Decisions about disclosing arthritis are challenging and cause anxiety. Young people associate good disease management and access to flexible and convenient care with their capacity to succeed in employment. Psychosocial and vocational interventions have benefited some young people but are not routinely available. Low expectations of employers may affect young people's decisions about disclosure and seeking appropriate support in the work place. Health professionals can equip young people with knowledge and skills to negotiate appropriate support, through signposting to antidiscrimination information and offering practice of transferable skills such as disclosure in consultations. Implications for rehabilitation Young people with juvenile idiopathic arthritis encounter challenges with regard to employment; many lack the knowledge and skills to negotiate appropriate support from employers. Rehabilitation professionals could play a more substantial role in equipping them with relevant knowledge and skills by signposting to antidiscrimination information and nurturing transferable skills, such as disclosure, in consultations. Potentially helpful interventions, such as group activities or assessment by a psychologist, have benefited some but need more evaluative scrutiny with respect to employment outcomes.

Background Adolescent juvenile offenders are at high risk for problems associated with drug use, including polysubstance use (i.e., use of a variety of drugs). The combination of juvenile offending and polysubstance use presents a significant public and child health concern. Objective This study explored polysubstance use among a sample of youth incarcerated for serious offenses. We examined several risk factors for substance use and delinquency (i.e., early and frequent substance use, prior history of arrests, school expulsion, Black ethnicity), as well as the association between aggression and polysubstance use. Methods Data were collected via questionnaires from 373 serious male juvenile offenders upon intake into a secure locked facility. Youth were on average 16 years old, and minority youth were overrepresented (28.1% Black, 53.1% Latino). Poisson regressions were used to assess the associations between the risk factors, aggression, and polysubstance use. Results Consistent with the literature, Black youth reported less polysubstance use and later age of drug use onset than White and Latino youth. Findings suggest that Latino juvenile offenders and those with an early and problematic pattern of substance use are at heightened risk for polysubstance use. Aggression was not significantly related to polysubstance use, over and above the risk factors. Conclusions Given that Latino youth experience low rates of treatment for substance use, the development of culturally-sensitive interventions for these youth is needed. Interventions should also be multifaceted to address the multitude of risk factors associated with polysubstance use among juvenile offenders. PMID:26997851

Do Juvenile Curfew Laws Reduce Underage Drinking?

2016-07-01

Although not originally enacted to deter the problem of underage drinking in the United States, one set of laws that may influence this behavior is juvenile curfew laws. This research asked the following: (a) What is the effect of enacting a juvenile curfew law on youth drinking, and (b) do demographic variables moderate the relation between juvenile curfew law enactment and drinking? This study examined the effect of juvenile curfew laws on underage drinking, using data from 46 U.S. cities from 1991 to 2005. In 2014, we compiled a data set containing alcohol and curfew law data by zip code. It included 63,081 minors (ages 12-17 years) from 1,081 zip codes. We used difference-in-difference regressions to analyze the data. The effect of the enactment of a curfew law on the likelihood of consuming alcohol in the past year or past 30 days or of heavy episodic drinking in the past 2 weeks was not significant when compared with cities without curfew laws during the same periods. Although the likelihood of consuming alcohol over the past year differed depending on an individual's characteristics (e.g., race/ethnicity, age, and gender), none of the interaction terms between these characteristics and curfew laws were significant. Curfew laws appear to have a nonsignificant effect on youth drinking, but these results are unclear without more knowledge as to where and when youth are drinking both before and after the enactment of curfew laws and how these laws are being enforced.

There is a growing consensus about the importance of mental health screening of youths in welfare and juvenile justice institutions. The Massachusetts Youth Screening Instrument-second version (MAYSI-2) was specifically designed, normed and validated to assist juvenile justice facilities in the United States of America (USA), in identifying youths with potential emotional or behavioral problems. However, it is not known if the USA norm-based cut-off scores can be used in Switzerland. Therefore, the primary purpose of the current study was to estimate the diagnostic performance and optimal cut-off scores of the MAYSI-2 in a sample of Swiss youths in welfare and juvenile justice institutions. As the sample was drawn from the French-, German- and Italian-speaking parts of Switzerland, the three languages were represented in the total sample of the current study and consequently we could estimate the diagnostic performance and the optimal cut-off scores of the MAYSI-2 for the language regions separately. The other main purpose of the current study was to identify potential gender differences in the diagnostic performance and optimal cut-off scores. Participants were 297 boys and 149 girls (mean age = 16.2, SD = 2.5) recruited from 64 youth welfare and juvenile justice institutions (drawn from the French-, German- and Italian-speaking parts of Switzerland). The MAYSI-2 was used to screen for mental health or behavioral problems that could require further evaluation. Psychiatric classification was based on the Schedule for Affective Disorders and Schizophrenia for School-Age Children, Present and Lifetime version (K-SADS-PL). The MAYSI-2 scores were submitted into Receiver-Operating Characteristic (ROC) analyses to estimate the diagnostic performance and optimal 'caution' cut-off scores of the MAYSI-2. The ROC analyses revealed that nearly all homotypic mappings of MAYSI-2 scales onto (cluster of) psychiatric disorders revealed above chance level accuracy. The optimal 'caution' cut-off scores derived from the ROC curve for predicting (cluster of) psychiatric disorders were, for several MAYSI-2 scales, comparable to the USA norm-based 'caution' cut-off scores. For some MAYSI-2 scales, however, higher optimal 'caution' cut-off scores were found. With adjusted optimal 'caution' cut-off scores, the MAYSI-2 screens potential emotional or behavioral problems well in a sample of Swiss youths in welfare and juvenile justice institutions. However, as for choosing the optimal 'caution' cut off score for the MAYSI-2, both language as well as gender seems to be of importance. The results of this study point to a compelling need to test the diagnostic performance and optimal 'caution' cut-off scores of the MAYSI-2 more elaborately in larger differentiated language samples in Europe.

Psychiatric disorder prevalence has been shown demonstrably higher among justice-involved adolescents than youth in the general population. Yet, among arrested juveniles, little is known regarding racial/ethnic differences in disorder prevalence, the role of trauma exposure in the diagnosis of behavioral disorders, or subsequent psychiatric treatment provided to adolescents with such diagnoses. The current study examines racial/ethnic disparity in psychiatric diagnoses and treatment of behavioral disorders associated with delinquency, controlling for traumatic experiences, behavioral indicators, and prior offending among serious juvenile offenders. Logistic regression is employed to explore the racial/ethnic disproportionality in behavioral disorder diagnoses and psychiatric treatment provision among 8763 males (57.7 % Black, 11.8 % Hispanic) and 1,347 females (53.7 % Black, 7.6 % Hispanic) admitted to long-term juvenile justice residential placements in Florida. The results indicate Black males are 40 % more likely, and Black females 54 % more likely to be diagnosed with conduct disorder than Whites, even upon considerations of trauma, behavioral indicators, and criminal offending. Black and Hispanic males are approximately 40 % less likely to be diagnosed with ADHD than White males, with no racial/ethnic differences for females. Importantly, Black males are 32 % less likely to receive psychiatric treatment than White males, with no differences between White and Hispanic males, or any female subgroups. Traumatic exposures increased the odds of oppositional defiant disorder and ADHD, but not conduct disorder for males, though adverse childhood experiences were unrelated to behavioral disorder diagnoses among females.

Altered behaviour and reduced survival of juvenile olive flounder, Paralichthys olivaceus, infected by an invasive monogenean, Neoheterobothrium hirame.

PubMed

Shirakashi, Sho; Teruya, Kazuhisa; Ogawa, Kazuo

2008-11-01

Neoheterobothriumhirame is a blood feeding monogenean of olive flounder Paralichthys olivaceus. The parasite was first reported in the mid-1990s from the Sea of Japan and became epidemic within cultured and wild flounder populations after several years. Infected fish often suffer from severe anaemia and thus the parasite is thought to have played an important role in the recent depletion of flounder populations in some areas of Japan. However, the causal mechanism underlying the parasite epidemic and decreases in host populations is unclear because apparently N. hirame infection is not fatal to the host. Here, we tested the hypothesis that N. hirame indirectly reduces the survival of wild juvenile flounder by altering their behaviour and making them more susceptible to predation. We conducted a series of experiments to compare behaviours and predation susceptibility between experimentally infected juvenile P. olivaceus and uninfected fish. Results showed that N. hirame infection increases the activity level, alters diel activity and has negative effects on burrowing performance and swimming endurance. When juvenile flounder cohabitated with predators, the survival rate of infected juveniles was approximately 25% less than that of uninfected fish. We believe this is the first empirical evidence linking N. hirame infection to death of the host through predation. Consequences of N. hirame-induced behavioural change for the survival of juvenile flounder in the wild are discussed. We conclude that recent outbreaks of N. hirame are likely to have been a key factor in the decline of flounder populations in Japan.

Juvenile sex offenders compared to non-sex offenders: a review of the literature 1995-2005.

2006-10-01

An unresolved but clinically important issue in the literature on juvenile delinquency is to what extent juvenile sex offenders resemble non-sex offenders with respect to individual, familial, and environmental characteristics. The current article reviewed published studies (1995-2005) comparing sex offenders with non-sex offenders. The 17 articles meeting the inclusion criteria suggest that differences exist between sex offenders and non-sex offenders on personality characteristics, behavioral problems, history of sexual abuse, nonsexual offending, and peer functioning. Inconsistent results were found for demographic factors, family functioning and background, antisocial attitudes, and intellectual and neurological functioning. Although it is likely that sex offenders can be differentiated from nonsex offenders on a number of characteristics, caution is warranted because of methodological differences between studies and small samples size. Also, studies show that sex offenders are a heterogeneous group. Further research should take into account this heterogeneity by including sex offenders from clearly circumscribed groups and investigating characteristics specifically related to sexual behavior.

Fitting a Structured Juvenile-Adult Model for Green Tree Frogs to Population Estimates from Capture-Mark-Recapture Field Data

We derive point and interval estimates for an urban population of green tree frogs (Hyla cinerea) from capture-mark-recapture field data obtained during the years 2006-2009. We present an infinite-dimensional least-squares approach which compares a mathematical population model to the statistical population estimates obtained from the field data. The model is composed of nonlinear first-order hyperbolic equations describing the dynamics of the amphibian population where individuals are divided into juveniles (tadpoles) and adults (frogs). To solve the least-squares problem, an explicit finite difference approximation is developed. Convergence results for the computed parameters are presented. Parameter estimates for the vital rates of juveniles and adults are obtained, and standard deviations for these estimates are computed. Numerical results for the model sensitivity with respect to these parameters are given. Finally, the above-mentioned parameter estimates are used to illustrate the long-time behavior of the population under investigation. ?? 2011 Society for Mathematical Biology.

This study aimed to describe the social, behavioural and offence characteristics of all convicted perpetrators of homicide aged 17 and under; to examine their previous contact with mental health services, and to discuss strategies for homicide prevention. An eight-year (1996-2004) sample of 363 juvenile homicide perpetrators in England and Wales was examined. The majority of perpetrators were male, used a sharp instrument, and most victims were acquaintances or strangers. Over half had previously offended. A history of alcohol and/or drug misuse was common, as was the prevalence of family dysfunction, abuse, educational difficulties or discipline problems. Previous contact with mental health services was rare. Earlier intervention targeting social and psychological adversity and substance misuse could help to reduce the level of risk for future violence, and may reduce homicide rates among juveniles. Strengthening engagement with young offenders and increasing resources to prevent recidivism may also be beneficial. Copyright © 2010 The Association for Professionals in Services for Adolescents.

The objective of the present study was to determine acute toxicity of copper, ammonia, or chlorine to larval (glochidia) and juvenile mussels using the recently published American Society for Testing and Materials (ASTM) Standard guide for conducting laboratory toxicity tests with freshwater mussels. Toxicity tests were conducted with glochidia (24- to 48-h exposures) and juveniles (96-h exposures) of up to 11 mussel species in reconstituted ASTM hard water using copper, ammonia, or chlorine as a toxicant. Copper and ammonia tests also were conducted with five commonly tested species, including cladocerans (Daphnia magna and Ceriodaphnia dubia; 48-h exposures), amphipod (Hyalella azteca; 48-h exposures), rainbow trout (Oncorhynchus mykiss; 96-h exposures), and fathead minnow (Pimephales promelas; 96-h exposures). Median effective concentrations (EC50s) for commonly tested species were >58 ??g Cu/L (except 15 ??g Cu/L for C. dubia) and >13 mg total ammonia N/L, whereas the EC50s for mussels in most cases were 40 ??g/L and above the FAV in the WQC for chlorine. The results indicate that the early life stages of mussels generally were more sensitive to copper and ammonia than other organisms and that, including mussel toxicity data in a revision to the WQC, would lower the WQC for copper or ammonia. Furthermore, including additional mussel data in 2007 WQC for copper based on biotic ligand model would further lower the WQC. ?? 2007 SETAC.

Effects of post-weaning social isolation and environment al enrichment on exploratory behavior and ankiety in Wistar rats.

Adverse early experience is generally regarded as a risk factor for both externalizing and internalizing behavioral disorders in humans. It can be modeled in rats by a post-weaning social isolation procedure. Effects of social isolation might possibly be ameliorated by environmental enrichment. In the current study, 24 male Wistar rats were divided post-weaning into four rearing conditions: control, environmental enrichment (EE), social isolation (SI) and a combination of the two experimental conditions; (EE+SI). Two observations of the effects of rearing conditions on the rate of social and object interactions were conducted during the juvenile and post-pubertal stages of development. The SI condition led to a marked increase of social interactions during the juvenile phase, but did not affect object interactions. The EE condition increased the level of social interactions during both the juvenile and post-pubertal measurements. The effects of early rearing conditions on adult exploratory behavior were less clear, with a significant difference between the groups obtained in one of three behavioral tests. Results suggest a general robustness in the development of adult exploratory behavior and anxiety when rats were exposed to early social isolation and provided brief opportunities for social play during the juvenile period. Further studies, aimed at distinguishing play-related protective factors serving against long-term adverse effects of juvenile social isolation, are suggested.

During 2004, the USGS Columbia River Research Laboratory conducted a study at McNary Dam using radio telemetry to estimate passage and survival parameters of juvenile salmonids. Our primary objective was to estimate these parameters under ambient environmental and operational conditions, and thus project-wide treatments were not implemented. The primary dam operation consisted of “biop” spill, where spill occurred at night between 1800 and 0600 hours, and no spill occurred between 0600 and 1800 hours for the majority of our study period. During the spring study period, we radio-tagged and released 1,896 yearling Chinook salmon and 1,888 juvenile steelhead. During the summer study period, we radio-tagged and released 1,919 subyearling Chinook salmon. All fish were tagged using gastric techniques to implant transmitters weighing 1.58 g for yearling Chinook salmon, 1.93 g for juvenile steelhead, and 0.96 g for subyearling Chinook salmon. Minimum fish sizes were based on a 6.5% tag:fish weight ratio, and the size of tagged fish represented about 91%, 100%, and 17% of the population, respectively for yearling Chinook salmon, juvenile steelhead, and subyearling Chinook salmon. About 60% of radio-tagged fish were released 10 km upstream of McNary Dam at Hat Rock State Park, Oregon, with the remainder released as control groups 400 m downstream of the dam.

The Influence of Stress on Juvenile Delinquency: Focusing on the Buffering Effects of Protective Factors among Korean Adolescents.

2017-01-01

The present study sought to examine self-control, parental support, and peer support as internal and external protective factors that buffer the influence of adolescent stress on delinquency among Korean adolescents. To this end, the paper utilized the 1st-year data from the Korea Youth Panel Study (KYPS) conducted by the National Youth Policy Institute; the study surveyed a total of 3,449 2nd-year middle school students. The results of the hierarchical regression analysis indicated that despite high levels of stress, high self-control mitigated the negative influence of stress on delinquency in adolescents. In contrast, parental and peer support were only found to be directly influential on juvenile delinquency. Parental support had only negative influences on status delinquency, and peer support had positive influences on both status and serious delinquency. Based on these results, we propose implications for preventing and intervening with juvenile delinquency.

Juvenile neuronal ceroid lipofuscinosis (JNCL) is characterized by severe visual impairment with onset around age 4-8 years, and a developmental course that includes blindness, epilepsy, speech problems, dementia, motor coordination problems, and emotional reactions. There is presently no cure and the disease leads to premature death. There have been few studies of non-medical intervention for individuals with JNCL, probably because of the negative prognosis. The present chapter discusses the education of children and adolescents with JNCL on the basis of current knowledge about the variation in perceptual, cognitive and language abilities through the course of the disease, and the possibilities that exist for supporting coping and learning within and outside the classroom. Adapted and special needs education may contribute significantly to improved learning conditions, better maintenance of skills and less frustration for individuals with JNCL.

Sports participation and juvenile delinquency: the role of the peer context among adolescent boys and girls with varied histories of problem behavior.

Gardner, Margo; Roth, Jodie; Brooks-Gunn, Jeanne

2009-03-01

In a study of 1,344 urban adolescents, the authors examined the relation between participation in organized sports and juvenile delinquency. They compared youth who participated in sports to those who only participated in nonathletic activities and to those who did not participate in any organized activities. They also examined the indirect relations between sports and delinquency via 2 peer-related constructs-deviant peer affiliations and unstructured socializing. Finally, they examined the extent to which gender and prior externalizing problems moderated the direct and indirect relations between sports participation and delinquency. The authors found that the odds of nonviolent delinquency were higher among boys who participated in sports when compared to boys who participated only in nonathletic activities but not when compared to boys who did not participate in any organized activities. Deviant peer affiliations and unstructured socializing mediated the relation between sports participation and boys' nonviolent delinquency. Moreover, prior externalizing problems moderated the mediated path through peer deviance. The authors did not, however, find direct, mediated, or moderated relations between sports and boys' violent delinquency nor between sports and girls' violent or nonviolent delinquency.

 Five juvenile Labrador Retrievers between the ages of 6 and 8 months were presented to our referral centres with a history of intermittent forelimb lameness.  The clinical examination revealed the presence of bilateral orthopaedic problems in four out of five cases.  Radiographic and computed tomography examinations showed the presence of a radiolucent defect corresponding to the area of insertion of the infraspinatus or supraspinatus tendons on the proximal humerus. Three dogs were concurrently affected by elbow disease on the contralateral forelimb and one dog with bilateral infraspinatus avulsion also had osteochondritis dissecans affecting both shoulder joints.  Avulsion of the insertion of the infraspinatus tendon in four dogs and of the supraspinatus tendon in one dog.  According to the current literature, the incidence of infraspinatus and supraspinatus tendinopathies in adult Labrador Retrievers is higher than in other breeds. In our five cases, the patients were juvenile and the nature of the injury was an avulsion of the tendinous insertion. Avulsion of the tendon of insertion of the infraspinatus or supraspinatus has been poorly described in the veterinary literature, and this would represent the first series of cases affecting juvenile Labrador Retrievers.

To review prevention programs, psychosocial and psychopharmacologic treatments, and service delivery configurations for children and adolescents with maladaptive aggression. To propose a research agenda for disorders of aggression in child and adolescent psychiatry. Recent empirical studies were reviewed using searches of MEDLINE and PsycINFO (text terms: aggression, antisocial, violence, conduct, oppositional, psychosocial treatment, psychopharmacology, and prevention), relevant books, review articles, and bibliographies. Articles met the following criteria: published in an English-language, peer-reviewed journal between 1980 and 2005, included a focus on individuals < 18 years old, and included an outcome measure of relevant significance. Results of 154 randomized, controlled psychosocial treatment trials, 20 controlled psychopharmacology studies, 4 open-label medication studies, and 2 psychopharmacology meta-analyses were reviewed. Prevention programs show promise for reducing future aggression in at-risk populations. Empirical support is available for the effectiveness of multifocused psychosocial treatments in reducing aggression in children and adolescents. Atypical antipsychotics, lithium, divalproex sodium, and stimulants for conduct problems associated with attention-deficit/hyperactivity disorder have empirical support for reducing aggression in selected patient populations. Therapeutic nihilism in the treatment of aggressive children and adolescents with conduct problems is no longer warranted. Multifocused psychosocial interventions given early in life to at-risk children have the most support for effectiveness. However, treatments for children who routinely present to the child psychiatrist with already well-established disorders of aggression are neither robust nor well-established. Further research into maladaptive aggression in referred children and adolescents within and across psychiatric diagnoses is important for the field of child and adolescent psychiatry.

The U.S.Geological Survey Great Lakes Science Center has conducted trawl surveys to assess annual changes in the deepwater demersal fish community of Lake Huron since 1973. Since 1992, surveys have been carried out using a 21 m wing trawl towed on-contour at depths ranging from 9 to 110 m on fixed transects. Sample sites include five ports in U.S. waters with less frequent sampling near Goderich, Ontario. The 2008 fall bottom trawl survey was carried out between October 24 and November 20, 2008 and sampled only the three northern U.S. ports at DeTour, Hammond Bay, and Alpena due to mechanical problems with the research vessel and prolonged periods of bad weather. Therefore, all data presented for 2008 are based on samples collected from these ports. Compared to previous years, alewife populations in Lake Huron remain at low levels after collapsing in 2004. Age-0 alewife density and biomass appears to have increased slightly but overall levels remain near the nadir observed in 2004. Density and biomass of adult and juvenile rainbow smelt showed a decrease from 2007 despite record-high abundance of juveniles observed in 2005, suggesting recruitment was low. Numbers of adult and juvenile bloater were low despite recent high year-classes. Abundances for most other prey species were similar to the low levels observed in 2005 - 2007. We captured one wild juvenile lake trout in 2008 representing the fifth consecutive year that wild lake trout were captured in the survey. Based on pairwise graphical comparisons and nonparametric correlation analyses, dynamics of prey abundance at the three northern ports followed lakewide trends since 1992. Density of benthic macroinvertebrates was at an all-time low in 2008 since sampling began in 2001. The decline in abundance was due to decreases in all taxonomic groups and a large reduction in recruitment of quagga mussels. Density of Diporeia at northern ports in 2008 was the lowest observed. Diporeia were found only at 73-m sites of three ports sampled in northern Lake Huron. While no lakewide estimate of prey biomass was calculated due to the limited spatial scope of the 2008 survey, existing data suggest prey biomass remains depressed. Prey available to salmonids during 2009 will likely be small alewives, small rainbow smelt and small bloaters. Predators in Lake Huron will continue to face potential prey shortages.

We conducted an evaluation of alterations produced in the valve closing speed of juvenile Argopecten ventricosus (Catarina scallop) exposed to the metals cadmium, chromium and lead, because of the connection of this response to the state of health of the mollusk. Bioassays were conducted with 50 juveniles (length 3 +/- 0.5 cm) exposed to 0.02, 0.1, 0.2 mg Cd l(-1); 0.1, 0.5, 1.0 mg Cr l(-1); 0.04, 0.2, 0.4 mg Pb l(-1) and 0.8 and 1.6 mg Cd + Cr + Pb l(-1) for 480 h. The average valve closing speed at the end of the experiment was under 1 s in the control group, from 2 to 3.6 s in the bioassays with cadmium, from 1.4 to 3.4 s with chromium, from 3 to 12 s with lead, and from 12 to 15 s with the metal mixtures. It was found that there are significant differences between the values recorded in assays with metals and the control (P < 0.05). The retardation of valve closing in the organisms exposed to toxic substances is probably caused by damage to the sensory cilia located on the edge of the mantle.

Skalski, John R.; Weiland, Mark A.; Ham, Kenneth D.

Survival studies of juvenile salmonids implanted with acoustic tags have been conducted at hydroelectric dams within the Federal Columbia River Power System (FCRPS) in the Columbia and Snake rivers between 2010 and 2014 to assess compliance with dam passage survival standards stipulated in the 2008 Biological Opinion (BiOp). For juvenile salmonids migrating downstream in the spring, dam passage survival defined as survival from the upstream dam face to the tailrace mixing zone must be ≥96% and for summer migrants, ≥93%, and estimated with a standard error ≤1.5% (i.e., 95% confidence interval of ±3%). A total of 29 compliance tests havemore » been conducted at 6 of 8 FCRPS main-stem dams, using over 109,000 acoustic-tagged salmonid smolts. Of these 29 compliance studies, 23 met the survival standards and 26 met the precision requirements. Of the 6 dams evaluated to date, individual survival estimates range from 0.9597 to 0.9868 for yearling Chinook Salmon, 0.9534 to 0.9952 for steelhead, and 0.9076 to 0.9789 for subyearling Chinook Salmon. These investigations suggest the large capital investment over the last 20 years to improve juvenile salmon passage through the FCRPS dams has been beneficial.« less

Effects of body size, condition, and lipid content on the survival of juvenile lake herring during rapid cooling events

Pangle, K.L.; Sutton, T.M.; Kinnunen, R.E.; Hoff, M.H.

2005-01-01

Juvenile lake herring Coregonus artedi were exposed to rapid cooling events during two laboratory experiments to determine the effects of body size, physiological condition, and lipid content on survival. The first experiment was conducted at the onset of winter, exposing small (50 to 85 mm) and large (85 to 129 mm) fish to a decline in water temperature from 12 to 2??C at a rate of 1??C/hr. During this experiment, both large and small individuals exposed to a rapid cooling event experienced no mortality or abnormal behaviors. Separate fish were then maintained under thermal and photoperiod regimes that mimicked those in Lake Superior from October through May. Fish in each size class were maintained at two feeding treatments: Artemia ad libitum and no food. At the completion of the winter period, these lake herring were subjected to the same rapid cooling event conducted in the first experiment. During the experiment, lake herring exhibited no mortality or abnormal behaviors despite treatment-dependent differences in condition and lipid content. Our results indicate that mortality due to rapid cooling events does not appear to contribute to the recruitment variability observed for juvenile lake herring in Lake Superior.

This study examined the utility of the Minnesota Multiphasic Personality Inventory-2-Restructured Form (MMPI-2-RF) substantive scales in the prediction of premature termination and therapy no-shows while controlling for other relevant predictors in a university-based community mental health center, a sample at high risk of both premature termination and no-show appointments. Participants included 457 individuals seeking services from a university-based psychology clinic. Results indicated that Juvenile Conduct Problems (JCP) predicted premature termination and Behavioral/Externalizing Dysfunction and JCP predicted number of no-shows, when accounting for initial severity of illness, personality disorder diagnosis, therapist experience, and other related MMPI-2-RF scales. The MMPI-2-RF Aesthetic-Literary Interests scale also predicted number of no-shows. Recommendations for applying these findings in clinical practice are discussed. © The Author(s) 2014.

Theoretical models concerning how neighborhood contexts adversely influence juvenile antisocial behavior frequently focus on urban neighborhoods; however, previous studies comparing urban and rural areas on the prevalence of youth antisocial behavior have yielded mixed results. The current study uses longitudinal data on the offspring of a nationally representative sample of mothers (N = 4,886) in the US. There was no relation between density and mother-reported child conduct problems across ages 4-13 years, but youth living in areas of greater population density exhibited more youth self-reported delinquency across 10-17 years. Families often moved to counties with greater or lesser population density, but longitudinal analyses treating population density as a time-varying covariate did not support the hypothesis that living in densely populated counties influenced youth delinquency. Rather, the association between population density and delinquency appears to be due to unmeasured selection variables that differ between families who live in more or less densely populated counties.

Female juvenile offenders exhibit high levels of anger, relational aggression, and physical aggression, but the population has long been ignored in research and practice. No anger management treatments have been developed specifically for this population, and no established anger management treatments are empirically supported for use with delinquent girls. Thus, to alleviate anger and reduce the frequency and severity of aggressive behaviors in this underserved population, we developed the gender-specific, Juvenile Justice Anger Management (JJAM) Treatment for Girls. This cognitive-behavioral intervention was adapted from the Coping Power Program (Lochman & Wells, 2002), a school-based anger management treatment for younger children that has established efficacy and effectiveness findings with its target populations. This paper describes how the content of JJAM was developed to meet the unique needs of adolescent girls in residential juvenile justice placements. It also traces the process of developing a manualized treatment and the steps taken to enhance efficacy and clinical utility. An overview of the treatment, a session-by-session outline, an example session activity, and an example homework assignment are provided. A randomized controlled trial is currently being conducted to evaluate the efficacy of the JJAM Treatment for Girls. PMID:27642247

"I see so much in them": Australian Chaplains telling an alternative narrative of adolescents in the justice system.

This qualitative study aims to provide insight into the impact of chaplaincy in the Australian juvenile justice system. Semi-structured qualitative interviews were conducted with six chaplains and managers of chaplaincy services in the juvenile justice system in Victoria, Australia. Interviews were analysed thematically using deductive and inductive coding. Four themes emerged relating to the role and impact of the chaplain: to establish a safe and trusting relationship with the adolescents, to convey love and belonging, to engage the adolescents in meaning making, and to help adolescents to realise their full potential. These themes are consistent with Maslow's Hierarchy of Needs. Two themes emerged regarding how to increase the reach of chaplaincy: through recognising chaplaincy as an integral part of the justice system and enabling chaplains to work with the adolescents and their families post-release. While limited by a small sample, this study represents all organisations that provide chaplaincy in the juvenile justice system in Victoria, Australia. Future research could include the voices of the adolescents in juvenile justice, to gain their perspective on the role and impact of chaplaincy services. © 2018 John Wiley & Sons Ltd.

The effect of prey density on foraging mode selection in juvenile lumpfish: balancing food intake with the metabolic cost of foraging.

PubMed

Killen, Shaun S; Brown, Joseph A; Gamperl, A Kurt

2007-07-01

1. In many species, individuals will alter their foraging strategy in response to changes in prey density. However, previous work has shown that prey density has differing effects on the foraging mode decisions of ectotherms as compared with endotherms. This is likely due to differences in metabolic demand; however, the relationship between metabolism and foraging mode choice in ectotherms has not been thoroughly studied. 2. Juvenile lumpfish Cyclopterus lumpus forage using one of two modes: they can actively search for prey while swimming, or they can 'sit-and-wait' for prey while clinging to the substrate using a ventral adhesive disk. The presence of these easily distinguishable foraging modes makes juvenile lumpfish ideal for the study of foraging mode choice in ectotherms. 3. Behavioural observations conducted during laboratory experiments showed that juvenile lumpfish predominantly use the 'cling' foraging mode when prey is abundant, but resort to the more costly 'swim' mode to seek out food when prey is scarce. The metabolic cost of active foraging was also quantified for juvenile lumpfish using swim-tunnel respirometry, and a model was devised to predict the prey density at which lumpfish should switch between the swim and cling foraging modes to maximize energy intake. 4. The results of this model do not agree with previous observations of lumpfish behaviour, and thus it appears that juvenile lumpfish do not try to maximize their net energetic gain. Instead, our data suggest that juvenile lumpfish forage in a manner that reduces activity and conserves space in their limited aerobic scope. This behavioural flexibility is of great benefit to this species, as it allows young individuals to divert energy towards growth as opposed to activity. In a broader context, our results support previous speculation that ectotherms often forage in a manner that maintains a minimum prey encounter rate, but does not necessarily maximize net energy gain.

Biological activities of marine benthos such as burrowing and feeding may change sediment characteristics. We conducted three experiments to examine the potential of using juveniles of a spoon worm Urechis unicinctus to improve the quality of organically contaminated coastal sediment. Sediment samples were collected from a site that was heavily contaminated with organic matter (Seonso) and two sites that were clean (Myo-do, Dolsan-do). Urechis juveniles, obtained by artificial fertilization and cultured in the laboratory, were introduced to the sediment (weight 3 kg, depth 10 cm) at a density of 500 individuals per aquarium (length 50 cm, width 35 cm, height 30 cm) (Experiment 1), or at densities ranging from 100 to 900 individuals per beaker (Experiment 2). To examine how sediment contamination can be modified by the effects of Urechis, 500 individuals (per aquarium) were exposed to the Seonso contaminated sediment that had been mixed with 0-100% clean sand (Experiment 3). Each experiment lasted two months and sediment samples were collected every 15 d to determine the several indexes of sediment quality, which included acid volatile sulfide (AVS), chemical oxygen demand (COD) and total ignition loss (TIL). In Experiment 1, the existence of Urechis did not result in significant changes in quality indexes in the sediments collected from Myo-do, Dolsan-do. However, AVS, COD and TIL of the Seonso sediment all decreased significantly after co-incubation with Urechis juveniles for 30 to 45 d. Experiment 2 showed that a density of at least 300 juveniles per beaker was necessary to significantly reduce all three quality indexes, and the magnitude of reduction was positively correlated with juvenile density. Experiment 3 revealed that Urechis juveniles were effective in reducing the AVS, COD and TIL of the Seonso sediment that had been mixed with 60%, 80%, and 80% of clean sand, respectively. The results of the present study therefore indicated that juveniles of this spoon worm have the potential to be used to improve the quality of organically contaminated sediment in coastal waters.

Objective: Although not originally enacted to deter the problem of underage drinking in the United States, one set of laws that may influence this behavior is juvenile curfew laws. This research asked the following: (a) What is the effect of enacting a juvenile curfew law on youth drinking, and (b) do demographic variables moderate the relation between juvenile curfew law enactment and drinking? This study examined the effect of juvenile curfew laws on underage drinking, using data from 46 U.S. cities from 1991 to 2005. Method: In 2014, we compiled a data set containing alcohol and curfew law data by zip code. It included 63,081 minors (ages 12–17 years) from 1,081 zip codes. We used difference-in-difference regressions to analyze the data. Results: The effect of the enactment of a curfew law on the likelihood of consuming alcohol in the past year or past 30 days or of heavy episodic drinking in the past 2 weeks was not significant when compared with cities without curfew laws during the same periods. Although the likelihood of consuming alcohol over the past year differed depending on an individual’s characteristics (e.g., race/ethnicity, age, and gender), none of the interaction terms between these characteristics and curfew laws were significant. Conclusions: Curfew laws appear to have a non-significant effect on youth drinking, but these results are unclear without more knowledge as to where and when youth are drinking both before and after the enactment of curfew laws and how these laws are being enforced.

An independent peer review was conducted on the draft version of this report utilizing three reviewers, each with different areas of expertise and different levels of knowledge regarding hydrodynamic modeling, fall Chinook biology, life history, and habitat requirements, and fishery issues relating to hydropower development and operations. Peer review comments have been incorporated into this final version.

Validity of juvenile idiopathic arthritis diagnoses using administrative health data.

Stringer, Elizabeth; Bernatsky, Sasha

2015-03-01

Administrative health databases are valuable sources of data for conducting research including disease surveillance, outcomes research, and processes of health care at the population level. There has been limited use of administrative data to conduct studies of pediatric rheumatic conditions and no studies validating case definitions in Canada. We report a validation study of incident cases of juvenile idiopathic arthritis in the Canadian province of Nova Scotia. Cases identified through administrative data algorithms were compared to diagnoses in a clinical database. The sensitivity of algorithms that included pediatric rheumatology specialist claims was 81-86%. However, 35-48% of cases that were identified could not be verified in the clinical database depending on the algorithm used. Our case definitions would likely lead to overestimates of disease burden. Our findings may be related to issues pertaining to the non-fee-for-service remuneration model in Nova Scotia, in particular, systematic issues related to the process of submitting claims.

Clarifying the link between childhood abuse history and psychopathic traits in adult criminal offenders

PubMed Central

2015-01-01

Childhood abuse is a risk factor for the development of externalizing characteristics and disorders, including antisocial personality disorder and psychopathy. However, the precise relationships between particular types of childhood maltreatment and subsequent antisocial and psychopathic traits remain unclear. Using a large sample of incarcerated adult male criminal offenders (n = 183), the current study confirmed that severity of overall childhood maltreatment was linked to severity of both psychopathy and antisocial personality disorder in adulthood. Moreover, this relationship was particularly strong for physical abuse and the antisocial facet of psychopathy. Sexual abuse history was uniquely related to juvenile conduct disorder severity, rather than adult psychopathy or antisocial behaviors. Additionally, there was a significantly stronger relationship between childhood maltreatment and juvenile conduct disorder than between childhood maltreatment and ASPD or psychopathy. These findings bolster and clarify the link between childhood maltreatment and antisocial behavior later in life. PMID:26389621

Effects of turbidity on predation vulnerability of juvenile humpback chub to rainbow and brown trout

Predation on juvenile native fish by introduced rainbow trout Oncorhynchus mykiss and brown trout Salmo trutta is considered a significant threat to the persistence of endangered humpback chub Gila cypha in the Colorado River in Grand Canyon. Diet studies of rainbow and brown trout in Glen and Grand canyons indicate that these species eat native fish, but impacts are difficult to assess because predation vulnerability is highly variable depending on the physical conditions under which the predation interactions take place. We conducted laboratory experiments to evaluate how short-term predation vulnerability of juvenile humpback chub changes in response to changes in turbidity. In overnight laboratory trials, we exposed hatchery-reared juvenile humpback chub and bonytail Gila elegans (a surrogate for humpback chub) to adult rainbow and brown trout at turbidities ranging from 0 to 1,000 formazin nephlometric units. We found that turbidity as low as 25 formazin nephlometric units significantly reduced predation vulnerability of bonytail to rainbow trout and led to a 36% mean increase in survival (24–60%, 95% CI) compared to trials conducted in clear water. Predation vulnerability of bonytail to brown trout at 25 formazin nephlometric units also decreased with increasing turbidity and resulted in a 25% increase in survival on average (17–32%, 95% CI). Understanding the effects of predation by trout on endangered humpback chub is important when evaluating management options aimed at preservation of native fishes in Grand Canyon National Park. This research suggests that relatively small changes in turbidity may be sufficient to alter predation dynamics of trout on humpback chub in the mainstem Colorado River and that turbidity manipulation may warrant further investigation as a fisheries management tool.

Given the growth of juvenile detainee populations, epidemiologic data on their psychiatric disorders are increasingly important. Yet, there are few empirical studies. Until we have better epidemiologic data, we cannot know how best to use the system's scarce mental health resources. Using the Diagnostic Interview Schedule for Children version 2.3, interviewers assessed a randomly selected, stratified sample of 1829 African American, non-Hispanic white, and Hispanic youth (1172 males, 657 females, ages 10-18 years) who were arrested and detained in Cook County, Illinois (which includes Chicago and surrounding suburbs). We present 6-month prevalence estimates by demographic subgroups (sex, race/ethnicity, and age) for the following disorders: affective disorders (major depressive episode, dysthymia, manic episode), anxiety (panic, separation anxiety, overanxious, generalized anxiety, and obsessive-compulsive disorders), psychosis, attention-deficit/hyperactivity disorder, disruptive behavior disorders (oppositional defiant disorder, conduct disorder), and substance use disorders (alcohol and other drugs). Nearly two thirds of males and nearly three quarters of females met diagnostic criteria for one or more psychiatric disorders. Excluding conduct disorder (common among detained youth), nearly 60% of males and more than two thirds of females met diagnostic criteria and had diagnosis-specific impairment for one or more psychiatric disorders. Half of males and almost half of females had a substance use disorder, and more than 40% of males and females met criteria for disruptive behavior disorders. Affective disorders were also prevalent, especially among females; more than 20% of females met criteria for a major depressive episode. Rates of many disorders were higher among females, non-Hispanic whites, and older adolescents. These results suggest substantial psychiatric morbidity among juvenile detainees. Youth with psychiatric disorders pose a challenge for the juvenile justice system and, after their release, for the larger mental health system.

Sediment toxicity tests compared chronic effects on survival, growth, and biomass of juvenile freshwater mussels (28-d exposures with Lampsilis siliquoidea) to the responses of standard test organisms—amphipods (28-d exposures with Hyalella azteca) and midges (10-d exposures with Chironomus dilutus)—in sediments from 2 lead–zinc mining areas: the Tri-State Mining District and Southeast Missouri Mining District. Mussel tests were conducted in sediments sieved to <0.25 mm to facilitate recovery of juvenile mussels (2–4 mo old). Sediments were contaminated primarily with lead, zinc, and cadmium, with greater zinc and cadmium concentrations in Tri-State sediments and greater lead concentrations in southeast Missouri sediments. The frequency of highly toxic responses (reduced 10% or more relative to reference sites) in Tri-State sediments was greatest for amphipod survival (25% of samples), midge biomass (20%), and mussel survival (14%). In southeast Missouri sediments, the frequency of highly toxic samples was greatest for mussel biomass (25%) and amphipod biomass (13%). Thresholds for metal toxicity to mussels, expressed as hazard quotients based on probable effect concentrations, were lower for southeast Missouri sediments than for Tri-State sediments. Southeast Missouri sites with toxic sediments had 2 or fewer live mussel taxa in a concurrent mussel population survey, compared with 7 to 26 taxa at reference sites. These results demonstrate that sediment toxicity tests with juvenile mussels can be conducted reliably by modifying existing standard methods; that the sensitivity of mussels to metals can be similar to or greater than standard test organisms; and that responses of mussels in laboratory toxicity tests are consistent with effects on wild mussel populations.

Food habits of Juvenile American Shad and dynamics of zooplankton in the lower Columbia River

As many as 2.4 million adult American shad annually pass John Day Dam, Columbia River to spawn upriver, yet food web interactions of juvenile shad rearing in John Day Reservoir are unexplored. We collected zooplankton and conducted mid-water trawls in McNary (June-July) and John Day reservoirs (August-November) from 1994 through 1996 during the outmigration of subyearling American shad and Chinook salmon. Juvenile American shad were abundant and represented over 98% of the trawl catch in late summer. The five major taxa collected in zooplankton tows were Bosmina longirostris, Daphnia, cyclopoid cope-pods, rotifers, and calanoid copepods. We evaluated total crustacean zooplankton abundance and Daphnia biomass in relation to water temperature, flow, depth, diel period, and cross-sectional location using multiple regression. Differences in zooplankton abundance were largely due to differences in water temperature and flow. Spatial variation in total zooplankton abundance was observed in McNary Reservoir, but not in John Day Reservoir. Juvenile American shad generally fed on numerically abundant prey, despite being less preferred than larger bodied zooplankton. A decrease in cladoceran abundance and size in August coupled with large percentages of Daphnia in juvenile American shad stomachs indicated heavy planktivory. Smaller juvenile American shad primarily fed on Daphnia in August, but switched to more evasive copepods as the mean size of fish increased and Daphnia abundance declined. Because Daphnia are particularly important prey items for subyearling Chinook salmon in mainstem reservoirs in mid to late summer, alterations in the cladoceran food base is of concern for the management of outmigrating salmonids and other Columbia River fishes. ?? 2006 by the Northwest Scientific Association.

Goulet, Richard R; Thompson, Patsy-A

2018-05-26

Uranium mining and milling release arsenic (As), nickel (Ni) and uranium (U) to receiving waters, which accumulate in sediments. The objective of this study was to investigate if As, Ni and U concentrations in tissue residue of Hyalella azteca, overlying water, sediment pore water and solids could predict juvenile and adult survival and growth in similar conditions to lake sediments downstream of Uranium mines and mills. We conducted 14 day, static sediment toxicity tests spiked with uranium, arsenic and nickel salts. For uranium, we spiked uranyl nitrate with sodium bicarbonate to limit U precipitation once in contact with circumneutral sediment. LC 50 for As, Ni and U of juveniles and adults based on measured concentrations in sediments were 1.8 and 2.2 µmol As/g dw, 6.3 and 13.4 µmol Ni/g dw and 0.2 and 0.9 µmol U/g dw, respectively. Adult survival and growth linearly decreased with increasing bioaccumulation. For juveniles, metal accumulation linearly predicted survival. We calculated lethal body concentrations (LBC 50 ) for juveniles and adults of 70 and 485 nmol As/g dw, 246 and 832 nmol Ni/g dw and 1.7 and 4.4 nmol U/g dw, respectively. The concentrations of As, Ni and U in tissue residue leading to a 20% decrease in growth were 427 nmol As/g, 755 nmol Ni/g and 5 nmol U/g. Overall, this study showed that Uranium was the most toxic element followed by As and Ni, that juveniles were more sensitive to the three metals tested than adults and that threshold body concentrations can support assessment of benthic invertebrate community impairment.

2014-01-01

Female juvenile offenders report high rates of sexual coercion and substance use, yet the temporal relationship between the two remains unclear. The focus of this study was to conduct a prospective examination of predictors of sexual coercion and substance use for a group of high-risk young women. Two hundred and forty five adolescent females (34% of a sample including males and females), between the ages of 14-17, and from a larger study of juvenile offenders, were recruited from juvenile probation offices to participate in a longitudinal study on substance use and sexual risk. At baseline, participants completed measures associated with increased risk for sexual coercion, including substance use, perceived relationship control, and externalizing behavior. At 6- and 24-month follow-up, participants also completed a measure assessing sexually coercive experiences. Path analysis revealed that less relationship control at baseline predicted sexual coercion at 6-months. Additionally, 6-month sexual coercion predicted alcohol use and sexual coercion at 24-month follow-up. Logistic regression analysis revealed also that alcohol use at 6-months predicted sexual revictimization at 24-months. Sexual coercion appears to be associated with subsequent increases in alcohol use, suggesting that female juvenile offenders may be using alcohol to cope with the psychological and emotional consequences of victimization. Alcohol use is linked to increased risk for repeat sexual coercion, suggesting that exposure to risky environments also may be important in understanding these girls' risk. Difficulties responding assertively in sexual relationships (i.e., low relationship control) also seem to increase female juvenile offenders' risk for sexual coercion. Finally, previous sexual coercion appears to increase risk for future victimization, highlighting the importance of early intervention for this at-risk group. PMID:25107488

Energetic cost of bot fly parasitism in free-ranging eastern chipmunks.

Careau, Vincent; Thomas, Donald W; Humphries, Murray M

2010-02-01

The energy and nutrient demands of parasites on their hosts are frequently invoked as an explanation for negative impacts of parasitism on host survival and reproductive success. Although cuterebrid bot flies are among the physically largest and most-studied insect parasites of mammals, the only study conducted on metabolic consequences of bot fly parasitism revealed a surprisingly small effect of bot flies on host metabolism. Here we test the prediction that bot fly parasitism increases the resting metabolic rate (RMR) of free-ranging eastern chipmunks (Tamias striatus), particularly in juveniles who have not previously encountered parasites and have to allocate energy to growth. We found no effect of bot fly parasitism on adults. In juveniles, however, we found that RMR strongly increased with the number of bot fly larvae hosted. For a subset of 12 juveniles during a year where parasite prevalence was particularly high, we also compared the RMR before versus during the peak of bot fly prevalence, allowing each individual to act as its own control. Each bot fly larva resulted in a approximately 7.6% increase in the RMR of its host while reducing juvenile growth rates. Finally, bot fly parasitism at the juvenile stage was positively correlated with adult stage RMR, suggesting persistent effects of bot flies on RMR. This study is the first to show an important effect of bot fly parasitism on the metabolism and growth of a wild mammal. Our work highlights the importance of studying cost of parasitism over multiple years in natural settings, as negative effects on hosts are more likely to emerge in periods of high energetic demand (e.g. growing juveniles) and/or in harsh environmental conditions (e.g. low food availability).

Terrestrial habitat selection and strong density-dependent mortality in recently metamorphosed amphibians.

2008-09-01

To predict the effects of terrestrial habitat change on amphibian populations, we need to know how amphibians respond to habitat heterogeneity, and whether habitat choice remains consistent throughout the life-history cycle. We conducted four experiments to evaluate how the spatial distribution of juvenile wood frogs, Rana sylvatica (including both overall abundance and localized density), was influenced by habitat choice and habitat structure, and how this relationship changed with spatial scale and behavioral phase. The four experiments included (1) habitat manipulation on replicated 10-ha landscapes surrounding breeding pools; (2) short-term experiments with individual frogs emigrating through a manipulated landscape of 1 m wide hexagonal patches; and habitat manipulations in (3) small (4-m2); and (4) large (100-m2) enclosures with multiple individuals to compare behavior both during and following emigration. The spatial distribution of juvenile wood frogs following emigration resulted from differences in the scale at which juvenile amphibians responded to habitat heterogeneity during active vs. settled behavioral phases. During emigration, juvenile wood frogs responded to coarse-scale variation in habitat (selection between 2.2-ha forest treatments) but not to fine-scale variation. After settling, however, animals showed habitat selection at much smaller scales (2-4 m2). This resulted in high densities of animals in small patches of suitable habitat where they experienced rapid mortality. No evidence of density-dependent habitat selection was seen, with juveniles typically choosing to remain at extremely high densities in high-quality habitat, rather than occupying low-quality habitat. These experiments demonstrate how prediction of the terrestrial distribution of juvenile amphibians requires understanding of the complex behavioral responses to habitat heterogeneity. Understanding these patterns is important, given that human alterations to amphibian habitats may generate extremely high densities of animals, resulting in high density-dependent mortality.

Although mental health disorders are common among incarcerated minors, psychiatric urgencies and emergencies often cannot be treated in juvenile detention facilities, necessitating emergency department (ED) transfers. The cost of this ED care has not been well studied. This study aimed to provide information on disposition and cost related to ED visits by juvenile hall patients transported for urgent psychiatric evaluation. A retrospective cross-sectional descriptive study of patients presenting to 1 ED from juvenile detention centers for consideration of psychiatric holds was conducted. Eligible patients were identified by a search of the International Classification of Diseases, Ninth Revision, discharge diagnosis codes and chart review. We collected information on patient demographics and disposition and calculated costs of ED visits, screening laboratories performed, inpatient stays on a medical ward, sitter and parole officer salaries, and ambulance transfers. One hundred eight patients accounting for 196 visits were transported from juvenile hall for urgent psychiatric evaluation. Of the 196 visits, 131 (67%) resulted in an involuntary psychiatric hold. More than half of the patients on hold (75 patients) were admitted to a medical ward for boarding because of lack of psychiatric inpatient beds. Included charges for the 196 visits during the 18-month period totaled US $1,357,884, with most of the costs due to boarding on the medical ward. We describe the magnitude and cost associated with addressing psychiatric emergencies in a juvenile correctional system relying on transport of patients to an ED for acute psychiatric evaluation and treatment. Further research is needed to determine if costs could be decreased by increasing psychiatric resources in juvenile detention centers.

The goal of Idaho Steelhead Monitoring and Evaluation Studies is to collect monitoring data to evaluate wild and natural steelhead populations in the Clearwater and Salmon river drainages. During 2007, intensive population data were collected in Fish Creek (Lochsa River tributary) and Rapid River (Little Salmon River tributary); extensive data were collected in other selected spawning tributaries. Weirs were operated in Fish Creek and Rapid River to estimate adult escapement and to collect samples for age determination and genetic analysis. Snorkel surveys were conducted in Fish Creek, Rapid River, and Boulder Creek (Little Salmon River tributary) to estimate parr density.more » Screw traps were operated in Fish Creek, Rapid River, Secesh River, and Big Creek to estimate juvenile emigrant abundance, to tag fish for survival estimation, and to collect samples for age determination and genetic analysis. The estimated wild adult steelhead escapement in Fish Creek was 81 fish and in Rapid River was 32 fish. We estimate that juvenile emigration was 24,127 fish from Fish Creek; 5,632 fish from Rapid River; and 43,674 fish from Big Creek. The Secesh trap was pulled for an extended period due to wildfires, so we did not estimate emigrant abundance for that location. In cooperation with Idaho Supplementation Studies, trap tenders PIT tagged 25,618 steelhead juveniles at 18 screw trap sites in the Clearwater and Salmon river drainages. To estimate age composition, 143 adult steelhead and 5,082 juvenile steelhead scale samples were collected. At the time of this report, 114 adult and 1,642 juvenile samples have been aged. Project personnel collected genetic samples from 122 adults and 839 juveniles. We sent 678 genetic samples to the IDFG Eagle Fish Genetics Laboratory for analysis. Water temperature was recorded at 37 locations in the Clearwater and Salmon river drainages.« less

To study the relationships between retrospective reports of physical punishment/maltreatment and rates of adjustment difficulties at age 18 in a birth cohort of New Zealand subjects. Data were gathered over the course of an 18 year longitudinal study of a birth cohort of 1,265 New Zealand born children. At age 18 retrospective reports of exposure to physical punishment/maltreatment were obtained. At this time the cohort was also assessed on measures of psychosocial adjustment juvenile offending, substance abuse behaviors, and psychiatric disorder. Young people reporting exposure to harsh or abusive treatment during childhood had elevated rates of juvenile offending, substance abuse, and mental health problems. However, subsequent analysis using logistic regression methods showed that much of the elevated risk shown by this group was explained by social and contextual factors that were associated with patterns of childhood punishment/maltreatment. Nonetheless, even after control for confounding factors those reporting harsh or abusive childhood experiences were at increased risks of violent offending, suicide attempts, being a victim of violence, and alcohol abuse. This study leads to three major conclusions: (1) Those exposed to harsh or abusive treatment during childhood are an at-risk population for juvenile offending, substance abuse, and mental health problems; (2) Much of this elevated risk arises from the social context within which harsh or abusive treatment occurs; (3) Nonetheless, exposure to abuse appears to increase risks of involvement in violent behavior and alcohol abuse.

Ford, Julian D; Grasso, Damion J; Hawke, Josephine; Chapman, John F

2013-10-01

This study replicates and extends the research literature on poly-victimization with a vulnerable and under-served population, juvenile justice-involved youths. N=1959, 10-16 year old youths (76% male; 74% youth of color) consecutively newly admitted to juvenile detention facilities completed psychometric measures of trauma history, posttraumatic stress, affect regulation, alcohol/drug use, suicide risk, and somatic complaints. Using latent class analysis derived from 19 types of adversity, three unique classes best fit the data. A poly-victim class (49% female, 51% youth of color) accounted for 5% of the sample and reported a mean of 11.4 (SD=1.1) types. A relatively moderate adversity class (31% female, 70% youth of color) accounted for 36% of the sample and reported a mean of 8.9 (SD=0.3) types of adversity and 2.65 (SD=1.1) types of traumatic adversity. A low adversity class (59% of the sample; 17% female, 78% youth of color) reported a mean of 7.4 (SD=0.4) adversity types but only 0.3 (SD=0.45) types of traumatic adversity. The relatively moderate adversity class was comparable to poly-victims in endorsing extensive non-victimization traumatic adversity (e.g., accidental and loss trauma), but poly-victims were distinct from both moderate and low adversity class members in the likelihood of reporting all but one type of traumatic victimization, multiple types of traumatic victimization, and severe emotional and behavioral problems. Girls were at particularly high risk of poly-victimization, and African American and White youths also were at risk for poly-victimization. Although youth involved in the juvenile justice system typically have experienced substantial victimization, a poly-victimized sub-group, especially (but not exclusively) girls, warrants particular scientific, clinical, and rehabilitative attention in order to address the most severe behavioral and mental health problems and risks faced by this vulnerable population.

There is a need for better knowledge about the relationship between sexual offending by young people and mental health problems. This study aimed to compare mental health problems between young people who commit sexual offences and those who do not. After completion of the Massachusetts Youth Screening Instrument-Version 2 (MAYSI-2), 334 young people who, according to MAYSI-2 information, had committed a sex offence were compared with 334 young people whose MAYSI-2 data suggested that they had not committed a sex offence. They were matched for age, race/ethnicity, type of facility and adjudication status. We also examined the young sex offenders for within group differences. The young sex offenders were less likely to report anger-irritability or substance misuse than the comparison youths. Within the sex offender group, older juveniles were more likely to report alcohol and drug use problems than younger ones, Caucasians were more likely to report anger and suicidal ideation than their non-Caucasian peers, those detained were more likely to report alcohol and drug use problems and somatic complaints than those on probation, and convicted youths were more likely to report alcohol and drug use problems and anger-irritability than those awaiting trial. Juvenile sexual offending seems less likely to be committed in the context of an anti-social lifestyle than other offending. Important findings among young sex offenders are their higher levels of mental health problems among those detained and convicted than among those on probation or awaiting trial. Assessment of the mental health of young sex offenders seems to be even more important the further they are into the justice system. Copyright © 2015 John Wiley & Sons, Ltd.

Chronic bacterial lung infections in cystic fibrosis (CF) are caused by defects in the CF transmembrane conductance regulator chloride channel. Previously, we described that newborn CF transmembrane conductance regulator-knockout ferrets rapidly develop lung infections within the first week of life. Here, we report a more slowly progressing lung bacterial colonization phenotype observed in juvenile to adult CF ferrets reared on a layered antibiotic regimen. Even on antibiotics, CF ferrets were still very susceptible to bacterial lung infection. The severity of lung histopathology ranged from mild to severe, and variably included mucus obstruction of the airways and submucosal glands, air trapping, atelectasis, bronchopneumonia, and interstitial pneumonia. In all CF lungs, significant numbers of bacteria were detected and impaired tracheal mucociliary clearance was observed. Although Streptococcus, Staphylococcus, and Enterococcus were observed most frequently in the lungs of CF animals, each animal displayed a predominant bacterial species that accounted for over 50% of the culturable bacteria, with no one bacterial taxon predominating in all animals. Matrix-assisted laser desorption-ionization time-of-flight mass spectrometry fingerprinting was used to quantify lung bacteria in 10 CF animals and demonstrated Streptococcus, Staphylococcus, Enterococcus, or Escherichia as the most abundant genera. Interestingly, there was significant overlap in the types of bacteria observed in the lung and intestine of a given CF animal, including bacterial taxa unique to the lung and gut of each CF animal analyzed. These findings demonstrate that CF ferrets develop lung disease during the juvenile and adult stages that is similar to patients with CF, and suggest that enteric bacterial flora may seed the lung of CF ferrets.

β-Adrenergic enhancement of neuronal excitability in the lateral amygdala is developmentally gated.

PubMed

Fink, Ann E; LeDoux, Joseph E

2018-05-01

Noradrenergic signaling in the amygdala is important for processing threats and other emotionally salient stimuli, and β-adrenergic receptor activation is known to enhance neuronal spiking in the lateral amygdala (LA) of juvenile animals. Nevertheless, intracellular recordings have not yet been conducted to determine the effect of β-adrenergic receptor activation on spike properties in the adult LA, despite the potential significance of developmental changes between adolescence and adulthood. Here we demonstrate that the β-adrenergic agonist isoproterenol (15 μM) enhances spike frequency in dorsal LA principal neurons of juvenile male C57BL/6 mice and fails to do so in strain- and sex-matched adults. Furthermore, we find that the age-dependent effect of isoproterenol on spike frequency is occluded by the GABA A receptor blocker picrotoxin (75 μM), suggesting that β-adrenergic receptors downregulate tonic inhibition specifically in juvenile animals. These findings indicate a significant shift during adolescence in the cellular mechanisms of β-adrenergic modulation in the amygdala. NEW & NOTEWORTHY β-Adrenergic receptors (β-ARs) in amygdala are important in processing emotionally salient stimuli. Most cellular recordings have examined juvenile animals, while behavioral data are often obtained from adults. We replicate findings showing that β-ARs enhance spiking of principal cells in the lateral amygdala of juveniles, but we fail to find this in adults. These findings have notable scientific and clinical implications regarding the noradrenergic modulation of threat processing, alterations of which underlie fear and anxiety disorders.

The U.S. Fish and Wildlife Service conducts an annual Waterfowl Parts Collection Survey to estimate composition of harvested waterfowl by species, sex, and age (i.e., juv or ad). The survey relies on interpretation of duck wings by a group of experienced biologists at annual meetings (hereafter, flyway wingbees). Our objectives were to estimate accuracy of age assignment at flyway wingbees and to explore how accuracy rates may influence bias of age composition estimates. We used banded mallards (Anas platyrhynchos; n = 791), wood ducks (Aix sponsa; n = 242), and blue-winged teal (Anas discors; n = 39) harvested and donated by hunters as our source of birds used in accuracy assessments. We sent wings of donated birds to wingbees after the 2002–2003 and 2003–2004 hunting seasons and compared species, sex, and age determinations made at wingbees with our assessments based on internal and external examination of birds and corresponding banding records. Determinations of species and sex of mallards, wood ducks, and blue-winged teal were accurate (>99%). Accuracy of aging adult mallards increased with harvest date, whereas accuracy of aging juvenile male wood ducks and juvenile blue-winged teal decreased with harvest date. Accuracy rates were highest (96% and 95%) for adult and juvenile mallards, moderate for adult and juvenile wood ducks (92% and 92%), and lowest for adult and juvenile blue-winged teal (84% and 82%). We used these estimates to calculate bias for all possible age compositions (0–100% proportion juv) and determined the range of age compositions estimated with acceptable levels of bias. Comparing these ranges with age compositions estimated from Parts Collection Surveys conducted from 1961 to 2008 revealed that mallard and wood duck age compositions were estimated with insignificant levels of bias in all national surveys. However, 69% of age compositions for blue-winged teal were estimated with an unacceptable level of bias. The low preliminary accuracy rates of aging blue-winged teal based on our limited sample suggest a more extensive accuracy assessment study may be considered for interpreting age compositions of this species.

Coming of age: how adolescent boys construct masculinities via substance use, juvenile delinquency, and recreation.

PubMed

Sanders, Jolene M

2011-01-01

This research aims to uncover aspects of adolescent masculine development among adult substance abusers. In-depth interviews and the resulting narrative provide the data for this exploratory analysis. Three main areas of adolescent masculinities are discussed: substance abuse, juvenile delinquency, and recreation. The findings are interpreted in light of Connell's conceptualization of hegemonic masculinities. Based on this sample, masculinities are constructed via a menu of adolescent behaviors that are descriptive of a working class lifestyle. It is the cultural context that sets the stage for substance abuse and its meaning to identity formation in adolescence, as well as in adulthood. Substance abuse in adolescence, along with other forms of juvenile delinquency and recreation, is a means of achieving masculinity. Unfortunately, for these men the use of substance abuse to achieve masculinity in adolescence becomes problematic later in adulthood. This article concludes that to successfully recover from substance abuse and addiction, these men must revisit and reframe their adolescent constructions of masculinity to better fit the problems and challenges they face as adults.

A compartmental model has been implemented on a microcomputer as an aid in the analysis of alternative solutions to a problem. The model, entitled Smolt Survival Simulator, simulates the survival of juvenile salmon during their downstream migration and passage of hydroelectric dams in the Columbia River. The model is designed to function in a workshop environment where resource managers and fisheries biologists can study alternative measures that may potentially increase juvenile anadromous fish survival during downriver migration. The potential application of the model has placed several requirements on the implementing software. It must be available for use in workshop settings.more » The software must be easily to use with minimal computer knowledge. Scenarios must be created and executed quickly and efficiently. Results must be immediately available. Software design emphasis vas placed on the user interface because of these requirements.

We reported 19 cases of school-aged children. They were initially judged to have learning difficulty or school maladaptation because of attention deficits, hyperactive behaviors or poor school performance, followed by the diagnosis such as degenerative or metabolic neurological diseases. The patients consisted of 4 cases of adrenoleukodystrophy, 5 cases of dentatorubral-pallidoluysian atrophy, 3 cases of Sanfilippo syndrome, 3 cases of subacute sclerosing panencephalitis, and each one case of juvenile Gaucher disease, juvenile Huntington disease, juvenile metachromatic leukodystrophy and Leigh disease. They had markedly poor school performance, and/or abnormal behaviors, followed by seizures, character disorders or psychomotor regression. The diagnostic clues included brain CT scan and/or MRI, peculiar facial appearance and notable family histories. When the children were indicated to have learning difficulty or maladjustment to school life, we should make deliberate differential diagnoses before concluding that they have a learning disorder and/or attention-deficit/hyperactivity disorder. Instead they should be recommended to visit child neurologists, when they present with any problems as aforesaid.

Gaps in service coordination between child welfare and other child-serving agencies are well documented. This article examines the gap between the child welfare and juvenile justice systems and discusses a program, Project Confirm, designed to reduce the problems associated with this gap. Project Confirm aims to improve cooperation between juvenile justice and child welfare agencies to prevent the unnecessary detention of arrested foster children in secure facilities. The program's design is outlined, and implementation statistics and government partner perceptions of the program in its first year of operations are provided. The article also identifies future challenges to implementation and discusses the broader implications of the program. In making this appeal for coordination and collaboration among public agencies, I'm not talking about pro forma integration efforts-I'm not talking about memoranda of understanding or top-level reorganizations that have autonomous agencies vaguely reporting to a single box labeled "human services." Rather, I'm talking about the much more challenging objective of achieving real working partnerships at the front line. (Nelson, 1998, p. 6)

Parent-child interaction therapy is an effective means to prevent and correct children's mental problems. Interactive interventions shown to be effective share common features: the focus is on the support of the parent's sensitivity, positive guiding ability and reflective capability. Simultaneous participation of both parents in the therapy, application of video observation and affirmation of positive collaborative relationship with the parents seem to increase the efficacy of the intervention. The above-mentioned elements are utilized in an interactive therapy method called Theraplay.

DENTAL LESIONS IN THE LOWLAND TAPIR (TAPIRUS TERRESTRIS).

Dental ailments, mandibular swelling, and dentoalveolar abscesses are common in tapirs, but knowledge about prevalence or etiology of these lesions in the Tapiridae family in general, and in lowland tapirs (Tapirus terrestris) in particular, is scarce. A recent study identified resorptive lesions of unknown etiology as a common problem in the Malayan tapir (Tapirus indicus). In order to investigate the type and prevalence of dental lesions occurring in lowland tapirs, and to compare these with findings with the Malayan tapir, skulls and teeth from 46 deceased lowland tapirs were visually and radiographically examined. The specimens were divided into subpopulations according to age (juveniles, young adults, adults) and origin (free-range or captive). Dental lesions were identified in 24% (11/46) of the study population. The most common pathologic findings were complicated dental fractures with associated periapical reaction (15%) and periapical reactions of various degrees without associated detectable dental pathology (13%). All these lesions likely originated from dental trauma. As in Malayan tapirs, juveniles had significantly fewer lesions than adults. This study shows that dental lesions present frequent problems for lowland tapirs, occurring both in captive and in free-ranging individuals, and indicates that increasing age should be considered a risk factor for the development of these lesions. Notably, the predominant dental problems in lowland tapirs and Malayan tapirs are not the same.

How does the Canadian juvenile justice system respond to detained youth with substance use associated problems? Gaps, challenges, and emerging issues.

PubMed

Erickson, Patricia G; Butters, Jennifer E

2005-01-01

Despite a juvenile justice system that, since its inception in 1908, has been predicated on meeting the rehabilitative needs of youth, Canada has few specialized programs for substance misusing young offenders, preferring more holistic approaches. This is in keeping with an addictions treatment system that has evolved recently in the direction of more integrated services within the general health care and social services delivery systems. In addition, Canada has tended to emphasize community-based over institutional treatment programs. Nevertheless, for youth in conflict with the law, "substance abuse" is recognized as a significant risk factor for recidivism. The approximately 9000 young persons held in custodial facilities on any given day across the country are exposed to a variety of programs aimed at reducing antisocial behavior and hence, re-offending. Some of these have a substance use component. Programs for Aboriginal youth offer some of the most innovative approaches for particular drug use problems. This article provides an overview of the Canadian response and elaborates features of some programs, particularly Multisystemic Therapy, mainly in the province of Ontario. Few programs have received adequate evaluation, however, and the need for systematic assessment is crucial for the development of future effective interventions for youth with multiple drug and other problems.

Juvenile hormone III (JH III) racemate was prepared from methyl (2E,6E)-farnesoate via epoxidation with 3-chloroperbenzoic acid (mCPBA). Enantioselective separation of JH III was conducted using normal-phase high-performance liquid chromatography (HPLC) on a chiral stationary phase. [(2)H(3)]Methyl (2E,6E)-farnesoate was also prepared from (2E,6E)-farnesoic acid and [(2)H(4)]methanol (methanol-d(4)) using 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC) and 4-dimethylaminopyridine (DMAP); the conjugated double bond underwent isomerization to some degree. Epoxidation of [(2)H(3)]methyl (2E,6E)-farnesoate with mCPBA gave a novel deuterium-substituted internal standard [(2)H(3)]JH III (JH III-d(3)). The standard curve was produced by linear regression using the peak area ratios of JH III and JH III-d(3) in liquid chromatography-mass spectrometry (LC-MS).

Development of Antisocial Personality Disorder in Detained Youth: The Predictive Value of Mental Disorders

2009-01-01

Antisocial personality disorder (APD) is a serious public and mental health concern. Understanding how well conduct disorder (CD) and other mental disorders predict the development of APD among youth involved in the juvenile justice system is critical for prevention. This study used a stratified random sample of 1112 detained youth to examine the development of APD at a three-year follow-up interview. Nearly one fifth of male juvenile detainees later developed APD; approximately one quarter of male juvenile detainees with CD at baseline later developed APD. Significantly more males than females developed APD; no differences were found by race/ethnicity. Having five or more symptoms of CD, dysthymia, alcohol use disorder, or generalized anxiety disorder was significantly associated with developing modified APD (M-APD; APD without the CD requirement). Some disorders were strong predictors of APD; however, none were adequate screeners for identifying which detainees would later develop M-APD. The findings of this study have implications for interventions and further research in developmental psychopathology. PMID:17469880

The effectiveness of the Stop Now and Plan (SNAP) program for boys at risk for violence and delinquency.

PubMed

Burke, Jeffrey D; Loeber, Rolf

2015-02-01

Among the available treatments for disruptive behavior problems, a need remains for additional service options to reduce antisocial behavior and prevent further development along delinquent and violent pathways. The Stop Now and Plan (SNAP) Program is an intervention for antisocial behavior among boys between 6 and 11. This paper describes a randomized controlled treatment effectiveness study of SNAP versus standard behavioral health services. The treatment program was delivered to youth with aggressive, rule-breaking, or antisocial behavior in excess of clinical criterion levels. Outcomes were measured at 3, 9, and 15 months from baseline. Youth in the SNAP condition showed significantly greater reduction in aggression, conduct problems, and overall externalizing behavior, as well as counts of oppositional defiant disorder and attention deficit hyperactivity disorder symptoms. Additional benefits for SNAP were observed on measures of depression and anxiety. Further analyses indicated that the SNAP program was more effective among those with a higher severity of initial behavioral problems. At 1 year follow-up, treatment benefits for SNAP were maintained on some outcome measures (aggression, ADHD and ODD, depression and anxiety) but not others. Although overall juvenile justice system contact was not significantly different, youth in SNAP had significantly fewer charges against them relative to those standard services. The SNAP Program, when contrasted with standard services alone, was associated with greater, clinically meaningful, reductions in targeted behaviors. It may be particularly effective for youth with more severe behavioral problems and may result in improvements in internalizing problems as well.

Molecular analysis of the XLRS1 gene in 4 females affected with X-linked juvenile retinoschisis.

X-linked juvenile retinoschisis (XLRS) is the most common cause of juvenile macular degeneration in males. Because of its X-linked mode of transmission, the disease is rare in females. In this article, we describe a mutation screen conducted on a family in which 4 female patients affected with XLRS presented with an unusually severe phenotype. DNA was extracted from peripheral blood, and the XLRS1 gene was amplified on DNA samples of all the available family members. The mutation screen was conducted by performing direct DNA sequencing using an MJ Research PTC-225 Peltier Thermal Cycler. A novel mutation, 588-593ins.C, was identified in exon 6 of the gene. The affected father was found to be heterozygous for the mutation, whereas all the female patients were homozygous for this mutation. The homozygosity of the mutation in the affected females led to severe phenotypes. The defective allele was expressed in infancy in 1 patient, whereas the disease manifested itself at variable ages in the other patients, reflecting a variation in the phenotype. This report describes a novel mutation in a family in which consanguinity has led to XLRS in 4 females. A variation in the phenotype of the disease is consistent with the published literature and suggests the involvement of genetic modifiers or environmental factors in influencing the clinical severity of the disease.

Partitioning loss rates of early juvenile blue crabs from seagrass habitats into mortality and emigration

Determining how post-settlement processes modify patterns of settlement is vital in understanding the spatial and temporal patterns of recruitment variability of species with open populations. Generally, either single components of post-settlement loss (mortality or emigration) are examined at a time, or else the total loss is examined without discrimination of mortality and emigration components. The role of mortality in the loss of early juvenile blue crabs, Callinectes sapidus, has been addressed in a few studies; however, the relative contribution of emigration has received little attention. We conducted mark-recapture experiments to examine the relative contribution of mortality and emigration to total loss rates of early juvenile blue crabs from seagrass habitats. Loss was partitioned into emigration and mortality components using a modified version of Jackson's (1939) square-within-a-square method. The field experiments assessed the effects of two size classes of early instars (J1-J2, J3-J5), two densities of juveniles (low: 16 m-2, high: 64 m-2), and time of day (day, night) on loss rates. In general, total loss rates of experimental juveniles and colonization rates by unmarked juveniles were extremely high (range = 10-57 crabs m-2/6 h and 17-51 crabs m-2/6 h, for loss and colonization, respectively). Total loss rates were higher at night than during the day, suggesting that juveniles (or potentially their predators) exhibit increased nocturnal activity. While colonization rates did not differ by time of day, J3-J5 juveniles demonstrated higher rates of colonization than J1-J2 crabs. Overall, there was high variability in both mortality and emigration, particularly for emigration. Average probabilities of mortality across all treatment combinations ranged from 0.25-0.67/6 h, while probabilities of emigration ranged from 0.29-0.72/6 h. Although mean mortality rates were greater than emigration rates in most treatments, the proportion of experimental trials in which crab loss from seagrass due to mortality was greater than losses due to emigration was not significantly different from 50%. Thus, mortality and emigration appear to contribute equally to juvenile loss in seagrass habitats. The difference in magnitude (absolute amount of loss) between mean emigration and mean mortality varied between size classes, such that differences between emigration and mortality were relatively small for J1-J2 crabs, but much larger for J3-J5 crabs. Further, mortality rates were density-dependent for J3-J5 juvenile stages but not for J1-J2 crabs, whereas emigration was inversely density-dependent among J3-J5 stages but not for J1-J2 instars. The co-dependency of mortality and emigration suggests that the loss term (emigration or mortality) which has the relatively stronger contribution to total loss may dictate the patterns of loss under different conditions. For older juveniles (J3-J5), emigration may only have a large impact on juvenile loss where densities are low, since the contribution of mortality appears to be much greater than emigration at high densities. The size-specific pattern of density-dependent mortality supports the notion of an ontogenetic habitat shift by early juvenile blue crabs from seagrass to unvegetated habitats, since larger individuals may experience increased mortality at high densities within seagrass beds. Qualitative comparisons between this study and a concurrent study of planktonic emigration of J1-J5 blue crabs (Blackmon and Eggleston, 2001) suggests that benthic emigration among J1-J2 blue crabs was greater than planktonic emigration; for J3-J5 stages benthic and planktonic emigration were nearly equal. This study demonstrates the potentially large role of emigration in recruitment processes and patterns of early juvenile blue crabs, and illustrates how juvenile size, juvenile density, and time of day can affect mortality and emigration rates as well as total loss and colonization.

The objective of the study was to determine the sensitivity of material properties of the juvenile spine to its external and internal responses using a finite element model under compression, and flexion-extension bending moments. The methodology included exercising the 8-year-old juvenile lumbar spine using parametric procedures. The model included the vertebral centrum, growth plates, laminae, pedicles, transverse processes and spinous processes; disc annulus and nucleus; and various ligaments. The sensitivity analysis was conducted by varying the modulus of elasticity for various components. The first simulation was done using mean material properties. Additional simulations were done for each component corresponding to low and high material property variations. External displacement/rotation and internal stress-strain responses were determined under compression and flexion-extension bending. Results indicated that, under compression, disc properties were more sensitive than bone properties, implying an elevated role of the disc under this mode. Under flexion-extension moments, ligament properties were more dominant than the other components, suggesting that various ligaments of the juvenile spine play a key role in modulating bending behaviors. Changes in the growth plate stress associated with ligament properties explained the importance of the growth plate in the pediatric spine with potential implications in progressive deformities.

Predation by northern pikeminnow on juvenile salmonids in The Dalles Dam tailrace: field, laboratory, and habitat modeling studies (FY2000)

Predation by resident fish is known to be a substantial cause of juvenile salmonid mortality, especially in dam tailraces and outfall locations. Conditions in The Dalles Dam tailrace are unique compared to other projects on the Columbia or Snake rivers, having a complex basin with a series of downriver islands where predators are known to reside. In May-June of 1999, northern pikeminnow and smallmouth bass were sampled in the tailrace of The Dalles Dam during periods immediately following the release of PIT-tagged juvenile salmonids for survival studies. Over twice as many smallmouth bass (N = 101) were collected as northern pikeminnow (N = 40), but none of the predators had PIT tags within their gut. A laboratory study was conducted to estimate the time required for PIT tags in juvenile salmonids to be evacuated from the gut of northern pikeminnow after consuming a tagged preyfish. Evacuation rate was sensitive to temperature, with median evacuation time being 21 h at 18 oC and 30 h at 14 oC. These results suggest that field studies to estimate predator population sizes, feeding rates, or predation on specific release groups would require considerably more effort than we allocated during 1999.

Liedtke, Theresa L.; Kock, Tobias J.; Hurst, William

2018-04-03

A multi-year evaluation was conducted during 2010–16 to evaluate passage survival of juvenile steelhead (Oncorhynchus mykiss), Chinook salmon (O. tshawytscha), and coho salmon (O. kisutch) in Lake Scanewa, and at Cowlitz Falls Dam in the upper Cowlitz River Basin, Washington. Reservoir passage survival was evaluated in 2010, 2011, and 2016, and included the tagging and release of 1,127 juvenile salmonids. Tagged fish were released directly into the Cowlitz and Cispus Rivers, 22.3 and 8.9 km, respectively, upstream of the reservoir, and were monitored as they moved downstream into, and through the reservoir. A single release-recapture survival model was used to analyze detection records and estimate reservoir passage survival, which was defined as successful passage from reservoir entry to arrival at Cowlitz Falls Dam. Tagged fish generally moved quickly downstream of the release sites and, on average, arrived in the dam forebay within 2 d of release. Median travel time from release to first detection at the dam ranged from 0.23 to 0.96 d for juvenile steelhead, from 0.15 to 1.11 d for juvenile coho salmon, and from 0.18 to 1.89 d for juvenile Chinook salmon. Minimum reservoir passage survival probabilities were 0.960 for steelhead, 0.855 for coho salmon and 0.900 for Chinook salmon.Dam passage survival was evaluated at the pilot-study level during 2013–16 and included the tagging and release of 2,512 juvenile salmonids. Juvenile Chinook salmon were evaluated during 2013–14, and juvenile steelhead and coho salmon were evaluated during 2015–16. A paired-release study design was used that included release sites located upstream and downstream of Cowlitz Falls Dam. The downstream release site was positioned at the downstream margin of the dam’s tailrace, which allowed dam passage survival to be measured in a manner that included mortality that occurred in the passage route and in the dam tailrace. More than one-half of the tagged Chinook salmon (52 percent) released upstream of Cowlitz Falls Dam moved downstream and passed the project; the remaining fish either remained upstream of the dam (37 percent) or were collected (11 percent). In 2015 and 2016, collection efficiencies at Cowlitz Falls Dam were abnormally high for juvenile steelhead and coho salmon, which resulted in few fish passing the dam. Seven percent of the tagged steelhead (40 fish) and 4 percent of the tagged coho salmon (18 fish) released upstream of the dam eventually passed the project, but these low numbers of fish precluded the estimation of meaningful survival estimates. Dam passage survival probability estimates for juvenile Chinook salmon were 0.828 in 2013 and 0.861 in 2014, lower than previously reported for turbine-specific passage Cowlitz Falls Dam.

Elevated streamflows increase dam passage by juvenile coho salmon during winter: Implications of climate change in the Pacific Northwest

2012-01-01

A 4-year evaluation was conducted to determine the proportion of juvenile coho salmon Oncorhynchus kisutch passing Cowlitz Falls Dam, on the Cowlitz River, Washington, during winter. River and reservoir populations of coho salmon parr were monitored using radiotelemetry to determine if streamflow increases resulted in increased downstream movement and dam passage. This was of interest because fish that pass downstream of Cowlitz Falls Dam become landlocked in Riffe Lake and are lost to the anadromous population. Higher proportions of reservoir-released fish (0.391-0.480) passed Cowlitz Falls Dam than did river-released fish (0.037-0.119). Event-time analyses demonstrated that streamflow increases were important predictors of dam passage rates during the study. The estimated effect of increasing streamflows on the risk of dam passage varied annually and ranged from 9% to 75% for every 28.3 m3/s increase in streamflow. These results have current management implications because they demonstrate the significance of dam passage by juvenile coho salmon during winter months when juvenile fish collection facilities are typically not operating. The results also have future management implications because climate change predictions suggest that peak streamflow timing for many watersheds in the Pacific Northwest will shift from late spring and early summer to winter. Increased occurrence of intense winter flood events is also expected. Our results demonstrate that juvenile coho salmon respond readily to streamflow increases and initiate downstream movements during winter months, which could result in increased passage at dams during these periods if climate change predictions are realized in the coming decades.

Social and Foraging Behavior in Northwestern Crows (Corvus caurinus): Incorporating New Analyses and Technology

NASA Astrophysics Data System (ADS)

Xu, Carol K.

Both foraging and social decisions impact animals in important ways. We investigate the effects of age on foraging efficiency and sociality on Northwestern Crows (Corvus caurinus) at the beach, and use the growing field of social network analysis (SNA) to further examine social behavior in these birds. Specifically, we predict that 1) adults are more efficient foragers than juveniles, 2) juveniles interact with larger numbers of social partners than adults, 3) juveniles and adults prefer to associate with each other rather than within their own age classes, 4) crows are not associating randomly while on the beach (aka they have preferred social partners), and 5) pairs of individuals engaging in more affiliative behaviors with each other are less likely to also behave agonistically to one another, and vice versa. We also explore the uses of a remote radio detection system Encounternet by testing the validity of pilot data collected through this system against live observations conducted simultaneously. There is no effect of age on foraging efficiency; however, juveniles were found to interact with more total partners than adults, and most social associations occur between juveniles and adults. Our results also suggest crows are engaging in preferential social associations, though there is no evidence that affiliative pairs and agonistic pairs are mutually exclusive. Finally, it appears Encounternet can be useful for data collection when paired with live observations, as long as certain limitations are kept in mind. Our pilot study could be beneficial to anyone considering the use of remote detection tools in data collection on animals.

2018-06-07

The pathogenicity of frog virus 3 (FV3)-like ranavirus varies in adult chelonian species at different environmental temperatures, but differences in pathogenicity at different temperatures has yet to be determined in juveniles. Our objective was to determine the susceptibility to FV3-like ranavirus in four species of juvenile chelonians: red-eared sliders (RES; Trachemys scripta elegans), Mississippi map turtles ( Graptemys pseudogeographica kohnii), false map turtles (FMT; Graptemys pseudogeographica), and eastern river cooters ( Pseudemys concinna concinna) at two environmental temperatures. Two simultaneous trials ( n=8 treatment and n=4 controls of each species) were conducted in separate temperature-controlled rooms with animals maintained at 22 C or 27 C. All of the inoculated animals of each species at each temperature died, but no mortality was observed in control animals. Median survival times varied between 8 d and 11 d, based on species and temperature, with RES in the 27 C trial surviving the shortest time and the FMT in the 22 C trial surviving the longest. Combining all species, turtles in the 27 C trial survived for fewer days than those housed at 22 C, despite all turtles in both trials having similar viral copies detected in postmortem tissues. Lesions in inoculated turtles resembled those noted in natural and experimental FV3-like ranavirus infections and included vasculitis, thrombosis, hemorrhage in multiple organs, renal tubular necrosis, and hepatic necrosis. Myositis was not present in any juvenile, infected turtles in this study. This study confirmed that juvenile chelonians have a high susceptibility to ranaviral disease.

Recruitment success and growth variability of mugilids in a West African estuary impacted by climate change

With the persistence of a drought since the late 1960s, some West African estuaries became permanently reversed in term of salinity gradient and hypersaline waters are present in their upstream part (salinity >60). To understand the mechanisms regulating fish recruitment intensity in these estuaries and evaluate the consequences of freshwater shortages on juvenile habitat quality, a growth study was conducted in the Saloum hypersaline estuary (Senegal). The Mugilidae fish family, highly representative of estuarine environments, was targeted and several species sampled (Chelon dumerili, Mugil bananensis and M. cf. curema sp. M). Juveniles were sampled monthly all the year round in three areas of the estuary exhibiting strongly contrasted habitat conditions. Otolith sections were used to estimate the ages, reconstruct growth trajectories, estimate the duration of the oceanic larval phase, and evaluate juvenile growth variability along the salinity gradient. Analyses revealed that the temporal recruitment variability of C. dumerili, with 2 annual cohorts, was not mainly induced by growth-selection mechanisms, but probably more by predation pressures. Juveniles exhibited significantly faster growth rates in the lower salinity suggesting that benthic food availability was a strong factor controlling habitat quality of early juveniles. Salinity had also a clear impact when reducing the growth in hypersaline conditions and/or selecting slower growing individuals. Moderate freshwater inputs positively affected the nursery function of the estuary for mugilids by enhancing the productivity of the first trophic levels. In a long term, the global change could have an impact of the mugilid fishery and its management.

Effects of pressure reductions in a proposed siphon water lift system at St. Stephen Dam, South Carolina, on mortality rates of juvenile American shad and blueback herring. Technical report

This report presents results of studies to predict the mortality rate of juvenile blueback herring (Alosa aestivalis) and American shad (A. sapidissima) associated with reduced pressure as they pass downstream through a proposed siphon water lift system at St. Stephen Dam, South Carolina. The primary function of the siphon is to increase attracting flow to better guide upstream migrating adult herring of both species into the existing fish lift for upstream passage. The US Army Engineer District, Charleston, wishes to consider the siphon as an alternative bypass route through the dam for downstream migrating juvenile and adult herring. A pressure-reductionmore » testing system that emulates some of the pressure characteristics of the siphon was used to determine the approximate percentage of juvenile fishes that could be reasonably expected to be killed passing through the reduced pressures anticipated for the siphon water lift system. The testing system could duplicate the range of pressure change anticipated for the siphon lift system but could not obtain pressures lower than 4.1 psi, whereas pressures for some design alternatives may approach the theoretical minimum pressure of 0.0 psi. Study results indicate that the mortality rate is probably about 20 percent. Power analysis indicates that mortality rate above 30 percent is unlikely. Conducting additional mortality studies is recommended to refine predicted mortality rates. Measures should be taken to prevent juvenile fish from entering the siphon lift system if excessive mortality rates are observed.« less

Total Dissolved Gas Effects on Fishes of the Lower Columbia River

McGrath, Kathy E.; Dawley, Earl; Geist, David R.

2006-03-31

Gas supersaturation problems generated by spill from dams on the Columbia River were first identified in the 1960s. Since that time, considerable research has been conducted on effects of gas supersaturation on aquatic life, primarily juvenile salmonids. Also since that time, modifications to dam structures and operations have reduced supersaturated gas levels produced by the dams. The limit for total dissolved gas saturation (TDGS) as mandated by current Environmental Protection Agency water quality standards is 110%. State management agencies issue limited waivers to water quality, allowing production of levels of up to 120% TDGS to facilitate the downstream migration ofmore » juvenile salmonids. Recently, gas supersaturation as a water quality issue has resurfaced as concerns have grown regarding chronic effects of spill-related total dissolved gas on salmonids, including incubating embryos and larvae, resident fish species, and other aquatic organisms. Because of current concerns, and because the last comprehensive review of research on supersaturation effects on fishes was conducted in 1997, we reviewed recent supersaturation literature to identify new or ongoing issues that may not be adequately addressed by the current 110% TDGS limit and the 120% TDGS water quality waiver. We found that recent work supports older research indicating that short-term exposure to levels up to 120% TDGS does not produce acute effects on migratory juvenile or adult salmonids when compensating depths are available. Monitoring programs at Snake and Columbia river dams from 1995 to the early 2000s documented a low incidence of significant gas bubble disease or mortality in Columbia River salmonids, resident fishes, or other taxa. We did, however, identify five areas of concern in which total dissolved gas levels lower than water quality limits may produce sublethal effects on fishes of the Columbia River. These areas of concern are 1) sensitive and vulnerable species or life stages, 2) long-term chronic or multiple exposure, 3) vulnerable habitats and reaches, 4) effects on incubating fish in hyporheic habitats, and 5) community and ecosystem effects. Although some of these areas of concern may have been identified previously in earlier works, we suggest that consideration of the issues is warranted to avoid detrimental impacts on aquatic resources of the Columbia River system. We discuss these issues and provide recommendations to regulatory and management agencies based on our review of recent literature. In general, we recommend that additional attention be directed toward resolving the uncertainties within these five areas.« less

Influence of sediment presence on freshwater mussel thermal tolerance

USGS Publications Warehouse

Archambault, Jennifer M.; Cope, W. Gregory; Kwak, Thomas J.

2014-01-01

Median lethal temperature (LT50) data from water-only exposures with the early life stages of freshwater mussels suggest that some species may be living near their upper thermal tolerances. However, evaluation of thermal sensitivity has never been conducted in sediment. Mussels live most of their lives burrowed in sediment, so understanding the effect of sediment on thermal sensitivity is a necessary step in evaluating the effectiveness of the water-only standard method, on which the regulatory framework for potential thermal criteria currently is based, as a test of thermal sensitivity. We developed a method for testing thermal sensitivity of juvenile mussels in sediment and used the method to assess thermal tolerance of 4 species across a range of temperatures common during summer. Stream beds may provide a thermal refuge in the wild, but we hypothesized that the presence of sediment alone does not alter thermal sensitivity. We also evaluated the effects of 2 temperature acclimation levels (22 and 27°C) and 2 water levels (watered and dewatered treatments). We then compared results from the sediment tests to those conducted using the water-only standard methods. We also conducted water-only LT tests with mussel larvae (glochidia) for comparison with the juvenile life stage. We found few consistent differences in thermal tolerance between sediment and water-only treatments, between acclimation temperatures, between waterlevel treatments, among species, or between juvenile and glochidial life stages (LT50 range = 33.3-37.2°C; mean = 35.6°C), supporting our hypothesis that the presence of sediment alone does not alter thermal sensitivity. The method we developed has potential for evaluating the role of other stressors (e.g., contaminants) in a more natural and complex environment.

Chronic bacterial lung infections in cystic fibrosis (CF) are caused by defects in the CF transmembrane conductance regulator chloride channel. Previously, we described that newborn CF transmembrane conductance regulator–knockout ferrets rapidly develop lung infections within the first week of life. Here, we report a more slowly progressing lung bacterial colonization phenotype observed in juvenile to adult CF ferrets reared on a layered antibiotic regimen. Even on antibiotics, CF ferrets were still very susceptible to bacterial lung infection. The severity of lung histopathology ranged from mild to severe, and variably included mucus obstruction of the airways and submucosal glands, air trapping, atelectasis, bronchopneumonia, and interstitial pneumonia. In all CF lungs, significant numbers of bacteria were detected and impaired tracheal mucociliary clearance was observed. Although Streptococcus, Staphylococcus, and Enterococcus were observed most frequently in the lungs of CF animals, each animal displayed a predominant bacterial species that accounted for over 50% of the culturable bacteria, with no one bacterial taxon predominating in all animals. Matrix-assisted laser desorption–ionization time-of-flight mass spectrometry fingerprinting was used to quantify lung bacteria in 10 CF animals and demonstrated Streptococcus, Staphylococcus, Enterococcus, or Escherichia as the most abundant genera. Interestingly, there was significant overlap in the types of bacteria observed in the lung and intestine of a given CF animal, including bacterial taxa unique to the lung and gut of each CF animal analyzed. These findings demonstrate that CF ferrets develop lung disease during the juvenile and adult stages that is similar to patients with CF, and suggest that enteric bacterial flora may seed the lung of CF ferrets.

Non-malignant fibrosing tumors in the pediatric hand or juvenile fibromatoses are clinically challenging because of their relatively infrequent occurrence and because of the variety of names associated with these diseases. We conducted a review of a personal case series of pediatric patients with these tumors and discuss here the more common histologic types and clinical characteristics of the disease spectrum in the context of the available published literature. All histologic samples were reviewed by a single pathologist. Infantile myofibromatosis, fibrous hamartoma of infancy, juvenile aponeurotic fibromatosis, palmar fibromatosis (Dupuytren’s type), infantile digital fibromatosis (Reye’s tumor), fibroma of the tendon sheath, and melorheostosis represent the encountered lesions.

Amani, Bita; Milburn, Norweeta G; Lopez, Susana; Young-Brinn, Angela; Castro, Lourdes; Lee, Alex; Bath, Eraka

We conducted focus groups with defense lawyers, clinicians, and education advocates to gather their perspectives on families' experiences with the juvenile justice system. Our quantitative descriptive analysis identified a range of themes such as discussions about the poor treatment of families as well as recommendations for a shifting of power to families. These perspectives may provide insights about the context in which families are expected to participate in interventions, meet probationary demands, and provide for their youth's well-being. The results support evidence gathered from families about the impact of youth incarceration on their lives and has implications for practitioners and researchers working with families whose youth have been incarcerated.

X-linked juvenile retinoschisis: mutations at the retinoschisis and Norrie disease gene loci?

PubMed

Hiraoka, M; Rossi, F; Trese, M T; Shastry, B S

2001-01-01

Juvenile retinoschisis (RS) and Norrie disease (ND) are X-linked recessive retinal disorders. Both disorders, in the majority of cases, are monogenic and are caused by mutations in the RS and ND genes, respectively. Here we report the identification of a family in which mutations in both the RS and ND genes are segregating with RS pathology. Although the mutations identified in this report were not functionally characterized with regard to their pathogenicity, it is likely that both of them are involved in RS pathology in the family analyzed. This suggests the complexity and digenic nature of monogenic human disorders in some cases. If this proves to be a widespread problem, it will complicate the strategies used to identify the genes involved in diseases and to develop methods for intervention.

Psychological characteristics of male 14- to 20-year-olds on probation and in a residential home in Hong Kong.

PubMed

Chui, Wing Hong; Chan, Heng Choon Oliver

2013-02-01

Little research has been conducted with Hong Kong juvenile probationers. The goals of this study are to examine the psychological characteristics of 14- to 20-year-old male probationers and to test their relationship with broad types of offending--violent and nonviolent. Participants were drawn from the only transitional housing facility for juvenile probationers aged 14-20 years. Offence types and numbers were rated from self-report. Various schedules were rated at interview with consenting young men to describe them in terms of eight psychological characteristics: self-esteem, life satisfaction, social bonding, positive affect, negative affect, impulsivity, pro-criminal attitude and self-perceived life problems. A total of 113 young men completed the assessment, 90% of those eligible. The average psychological profile of these young men was fairly typical for their communities. Pro-criminal attitudes, however, correlated with both main types of offending, whereas main affective state was differently associated. Predominantly, negative affect was associated with violent offending and predominantly positive affect with nonviolent offending. Participants in this study generally reported higher levels of positive psychological well-being than in previous nondelinquent Chinese samples. IMPLICATIONS FOR PRACTICE AND FUTURE RESEARCH: A case-control study comparing such offenders with nondelinquents is required to clarify these findings. A longitudinal design is now indicated to test the direction of relationships between psychological indicators and offending. These steps would be useful precursors to a service evaluation of probation hostels for young offenders. Copyright © 2013 John Wiley & Sons, Ltd.

Life stage sensitivity of the marine mussel Mytilus edulis to ammonia.

Kennedy, Alan J; Lindsay, James H; Biedenbach, James M; Harmon, Ashley R

2017-01-01

Ammonia is an important contaminant to consider in all toxicity tests. It is especially important to consider the impacts of ammonia in test methods that use sensitive water column organisms exposed to sediments or sediment extracts, such as porewater and elutriate toxicity tests. Embryo-larval development toxicity tests, such as the 48-h method using Mytilus mussel species, are particularly sensitive to ammonia. To better understand the effect thresholds across different life stages of these mussels, 6 short-term (48-h) development toxicity tests and 3 21-d toxicity tests with different-sized juvenile mussels were conducted. Two of the juvenile mussel tests involved 21-d continuous chronic exposure to ammonia, whereas the third involved an acute 2-d ammonia exposure, followed by a 19-d recovery period. The embryo-larval development test method (50% effect concentration [EC50] = 0.14-0.18 mg/L un-ionized ammonia) was 2.5 times more sensitive than the juvenile mussel 21-d survival endpoint (50% lethal concentration = 0.39 mg/L un-ionized ammonia) and 2 times more sensitive than the most sensitive sublethal juvenile mussel endpoint (EC50 = 0.26 mg/L un-ionized ammonia). Further, it was found that the juveniles recovered from a 48-h exposure to un-ionized ammonia of up to 1.1 mg/L. The data generated suggest that the embryo development endpoint was sufficiently sensitive to un-ionized ammonia to protect the chronically exposed (21 d) juvenile mussels.

Effects of multiple acute stressors on the predator avoidance ability and physiology of juvenile Chinook salmon

USGS Publications Warehouse

Mesa, Matthew G.

1994-01-01

Northern squaw fish Ptychocheilus oregonensis are the predominant predators of juvenile Pacific salmonids Oncorhynchus spp. in the Columbia River, and their predation rates are greatest just below dams. Because juvenile salmonids are commonly subjected to multiple stressors at dams in the course of their seaward migration, high predation rates below dams may be due in part to an increase in the vulnerability of stressed fish. I conducted laboratory experiments to examine the predator avoidance ability and physiological stress responses of juvenile chinook salmon O. tshawytscha subjected to treatments (stressors) designed to simulate routine hatchery practices (multiple handlings) or dam passage (multiple agitations). Both stressors resulted in lethargic behavior in the fish, and agitation also caused disorieniation and occasional injury. When equal numbers of stressed and unstressed fish were exposed to northern squawfish for up to 1 h, significantly more stressed fish were eaten, but this effect was not evident during longer exposures. The lack of differential predation in trials lasting up to 24 h can be explained by the rapid development of schooling behavior in the prey, but other possibilities exist, such as changing ratios of stressed and unstressed prey over time. Concentrations of plasma cortisol, glucose, and lactate in fish subjected to multiple stressors were similar and sometimes cumulative, returned to prestress levels within 6-24 h, and correlated poorly with predator avoidance ability. My results suggest that juvenile salmonids are capable of avoiding predators within 1 h after being subjected to multiple acute stressors even though physiological homeostasis may be altered for up to 24 h. Therefore, because juvenile salmonids typically reside in lailrace areas for only a short time after dam passage, measures aimed at reducing physical stress or protecting them as they migrate through dam tailraces may help alleviate the relatively intense predation in these areas.

The study reported herein was funded as part of the Anadromous Fish Evaluation Program, which is managed by the U.S. Army Corps of Engineers (USACE). The Anadromous Fish Evaluation Program study code is EST P 02 01: A Study of Salmonid Survival and Behavior through the Columbia River Estuary Using Acoustic Tags. The study was conducted by the Pacific Northwest National Laboratory (PNNL) and National Oceanic and Atmospheric Administration (NOAA) Fisheries for the USACE Portland District. Estimated survival of acoustic-tagged juvenile Chinook salmon and steelhead through the lower Columbia River and estuary in 2009 was lowest in the final 50more » km of the estuary. Probability of survival was relatively high (>0.90) for yearling and subyearling Chinook salmon from the Bonneville Dam forebay (rkm 236) to Three-tree Point (rkm 49.6). Survival of juvenile Chinook salmon declined sharply through the lower 50 km of the estuary. Acoustic-tagged steelhead smolts did not survive as well as juvenile Chinook salmon between Bonneville Dam and the mouth of the Columbia River. Steelhead survival began to decline farther upstream (at rkm 86) relative to that of the Chinook salmon stocks. Subyearling Chinook salmon survival decreased markedly as the season progressed. It remains to be determined whether later migrating subyearling Chinook salmon are suffering increasing mortality as the season progresses or whether some portion of the apparent loss is due to fish extending their freshwater residence. This study provided the first glimpse into what promises to be a very informative way to learn more about how juvenile salmonid passage experiences through the FCRPS may influence their subsequent survival after passing Bonneville Dam. New information regarding the influence of migration pathway through the lower 50 km of the Columbia River estuary on probability of survival of juvenile salmonids, combined with increased understanding regarding the foraging distances and time periods of avian predators should prove useful in developing or assessing management actions to reduce losses of juvenile salmonid smolts that attempt to pass through the estuary on their seaward migration.« less

Small piscivores are regarded as important regulators of the composition of coral reef fish communities, but few studies have investigated their predatory ecology or impact on assemblages of juvenile fishes. This study investigated the foraging ecology of a common coral reef predator, the dottyback Pseudochromis fuscus, using underwater focal animal observations. Observations were conducted at two times of year: the summer, when recruit fishes were an available food item and winter, when remaining juveniles had outgrown vulnerability to P. fuscus. During the summer, P. fuscus directed 76% of its strikes at invertebrates and 24% at recruiting juvenile fishes. When striking at fishes, P. fuscus exhibited two distinct feeding modes: an ambush (26% successful) and a pursuit mode (5% successful). Predator activity in the field peaked at midday, averaging 2.5 captures h-1 of juvenile fishes. Monitoring of activity and foraging in the laboratory over 24-h periods found that P. fuscus was a diurnal predator and was active for 13 h d-1 during the summer. The number of hours during which foraging was recorded differed greatly among individuals ( n = 10), ranging from 4 to 13 h. The number of predatory strikes did not increase with standard length, but the success rate and consumption rate of juvenile fishes did increase with size. Estimated hourly mortality on juvenile fish ranged from 0.49 fish h-1 in small P. fuscus individuals (30-39 mm standard length, SL; equating to 6.3 per 13 h day) to 2.4 fish h-1 in large P. fuscus individuals (55-65 mm SL; 30.6 per 13 h day). During the winter, P. fuscus struck at invertebrates with a similar rate to the summer period. These observations of the predatory ecology of P. fuscus support the hypothesis that in coral reef systems, small piscivores, because of their high metabolism and activity, are probably important regulators of coral reef fish community composition.

Assessment of resource selection models to predict occurrence of five juvenile flatfish species (Pleuronectidae) over the continental shelf in the western Gulf of Alaska

According to the nursery size hypothesis, flatfish recruitment is constrained by nursery area. Thus, if resource selection models can be shown to accurately predict the location and geographic extent of flatfish nursery areas, they will become important tools in the management and study of flatfish population dynamics. We demonstrate that some resource selection models derived previously to predict the presence and absence of juvenile flatfishes near shore were applicable to the broader continental shelf. For other age-species groups, derivation of new models for the continental shelf was necessary. Our study was conducted in the western Gulf of Alaska (GoA) during October 2011 on four groups of age-0 juvenile flatfishes: Pacific halibut (Hippoglossus stenolepis), arrowtooth flounder (Atheresthes stomias), northern rock sole (Lepidopsetta polyxystra), and flathead sole (Hippoglossoides elassodon); and three groups of age-1 juvenile flatfishes: northern rock sole, flathead sole, and yellowfin sole (Limanda aspera). Sampling occurred at 33 sites across the continental shelf. Fish were collected using a 3-m beam trawl, and a midwater trawl. Environmental data were collected on sediment composition and water temperature and depth. Many of the age-species groups co-occurred in the Shumagin and Barnabus sea valleys; however, age-0 arrowtooth flounder occurred at more locations than other juveniles, perhaps due to a relatively broad tolerance of environmental conditions and to the utilization of midwater habitat. Thus, the large nursery area of arrowtooth flounder may be one reason why they are currently the most abundant GoA flatfish. In fact, among all species, mean recruitment at age 3 increased with the percent occurrence of age-0 juveniles at the 33 sites, a proxy for relative nursery area, in accordance with the nursery size hypothesis, suggesting that mean recruitment among GoA flatfishes is structured by nursery size.

Multidimensional family therapy HIV/STD risk-reduction intervention: an integrative family-based model for drug-involved juvenile offenders.

2009-03-01

Drug and juvenile justice involved youths show remarkably high rates of human immunodeficiency virus (HIV)/sexually transmitted disease (STD) risk behaviors. However, existing interventions aimed at reducing adolescent HIV risk behavior have rarely targeted these vulnerable young adolescents, and many approaches focus on individual-level change without attention to family or contextual influences. We describe a new, family-based HIV/ STD prevention model that embeds HIV/STD focused multifamily groups within an adolescent drug abuse and delinquency evidence-based treatment, Multidimensional Family Therapy (MDFT). The approach has been evaluated in a multisite randomized clinical trial with juvenile justice involved youths in the National Institute on Drug Abuse Criminal Justice Drug Abuse Treatment Studies (www.cjdats.org). Preliminary baseline to 6-month outcomes are promising. We describe research on family risk and protective factors for adolescent problem behaviors, and offer a rationale for family-based approaches to reduce HIV/STD risk in this population. We describe the development and implementation of the Multidimensional Family Therapy HIV/STD risk-reduction intervention (MDFT-HIV/ STD) in terms of using multifamily groups and their integration in standard MDFT and also offers a clinical vignette. The potential significance of this empirically based intervention development work is high; MDFT-HIV/STD is the first model to address largely unmet HIV/STD prevention and sexual health needs of substance abusing juvenile offenders within the context of a family-oriented evidence-based intervention.

Moral judgment and conduct disorder intensity in adolescents involved in delinquency: matching controls by school grade.

PubMed

Chudzik, Lionel

2007-08-01

Most studies that have found associations between delinquency and moral judgment generally compare incarcerated juveniles with adolescents in normal schooling. However, this comparison is subject to two criticisms. First, a large number of adolescents in school who are not charged with any crime in the legal system are still involved in unlawful behaviour. Second, adolescents involved with delinquency often have difficulties at school. The aim of the present study was to measure this association by matching a sample of adolescents involved with delinquency (n=18, M age=15.8, SD=1.1) to adolescents not involved in delinquency (n=42, M age=15.8, SD=0.8) according to their school grade and Conduct Disorder Intensity as measured by a self-report index using DSM-IV diagnostic criteria. Participants who met four or more criteria were assigned to the High Conduct Disorder group (n=28), and the rest were assigned to the Low Conduct Disorder group (n=32). Their level of moral judgment was evaluated with the French version of the Sociomoral Reflection Measure-Short Form by Gibbs, Basinger, and Fuller, inspired by Kohlberg's model of moral development. Findings demonstrate that in both samples, adolescents in the High Conduct Disorder group presented moral judgment that was significantly less mature than that of adolescents in the Low Conduct Disorder group. However, the majority of participants in the Low Conduct Disorder group also scored low on the Sociomoral Reflection Measure-Short Form, suggesting more immature moral judgment. The bias introduced by the mode of recruitment in most comparisons of adolescents involved with delinquency to adolescents with no delinquency problems is discussed, and an argument is made for the importance of analysing moral judgment development within a framework of general cognitive development.

2008-01-01

The objective of the present study was to evaluate the influence of pH on the toxicity of ammonia to juvenile freshwater mussels. Acute 96-h ammonia toxicity tests were conducted with 10-d-old juvenile mussels (fatmucket, Lampsilis siliquoidea) at five pH levels ranging from 6.5 to 9.0 in flow-through diluter systems at 20??C. Acute 48-h tests with amphipods (Hyalella azteca) and 96-h tests with oligochaetes (Lumbriculus variegatus) were conducted concurrently under the same test conditions to determine the sensitivity of mussels relative to these two commonly tested benthic invertebrate species. During the exposure, pH levels were maintained within 0.1 of a pH unit and ammonia concentrations were relatively constant through time (coefficient of variation for ammonia concentrations ranged from 2 to 30% with a median value of 7.9%). The median effective concentrations (EC50s) of total ammonia nitrogen (N) for mussels were at least two to six times lower than the EC50s for amphipods and oligochaetes, and the EC50s for mussels decreased with increasing pH and ranged from 88 mg N/L at pH 6.6 to 0.96 mg N/L at pH 9.0. The EC50s for mussels were at or below the final acute values used to derive the U.S. Environmental Protection Agency's acute water quality criterion (WQC). However, the quantitative relationship between pH and ammonia toxicity to juvenile mussels was similar to the average relationship for other taxa reported in the WQC. These results indicate that including mussel toxicity data in a revision to the WQC would lower the acute criterion but not change the WQC mathematical representation of the relative effect of pH on ammonia toxicity. ?? 2008 SETAC.

2009-01-01

The purpose of this study was to identify the clinical and demographic characteristics of adolescent females admitted to a psychiatric hospital who meet the criteria for Juvenile Primary Fibromyalgia Syndrome (JPFS). Participants (n = 62) were adolescent females, ages 12 to 18 years who were admitted to an inpatient psychiatric unit. The participants completed four questionnaires: The Achenbach Youth Self-Report (YSR), the Children's Somatization Inventory (CSI), the Fibromyalgia Impact Questionnaire modified for children (FIQ-C) and the Pain Symptom Questionnaire (PSQ). Then participants were interviewed to assess the Yunus and Masi JPFS criteria. The interview included an examination of 21 (18 bilateral and 3 control) tender points. Of the 62 adolescent females enrolled, 52% (n = 32) met criteria for JPFS (i.e. JPFS cases). Both the FIQ and CSI scores were significantly elevated for JPFS cases as compared with non-cases (p = .0001 and p = .0012 respectively). Cases of JPFS also scored significantly higher on the anxiety, depression, and conduct disorder scales of the YSR. No between-group differences were found in reports of physical or sexual abuse. However, a consistently higher percentage of JPFS cases reported physical or sexual abuse as a child. Juvenile primary fibromyalgia is highly prevalent in an adolescent inpatient psychiatric unit. This possibility should be taken into consideration when chronic complaints of pain are expressed by patients in this setting, especially in those who have conduct-related issues. The connection between JPFS and abuse history requires further investigation.

Purpose: To describe the results of conformal radiotherapy in advanced juvenile nasopharyngeal angiofibroma in a tertiary care institution. Methods and Materials: Retrospective chart review was conducted for 8 patients treated with conformal radiotherapy between 2006 and 2009. The median follow-up was 17 months. All patients had Stage IIIB disease with intracranial extension. Radiotherapy was considered as treatment because patients were deemed inoperable owing to extensive intracranial/intraorbital extension or proximity to optic nerve. All but 1 patient were treated with intensity-modulated radiotherapy using seven coplanar fields. Median (range) dose prescribed was 39.6 (30-46) Gy. Actuarial analysis of local control and descriptivemore » analysis of toxicity profile was conducted. Results: Despite the large and complex target volume (median planning target volume, 292 cm{sup 3}), intensity-modulated radiotherapy achieved conformal dose distributions (median van't Reit index, 0.66). Significant sparing of the surrounding organs at risk was obtained. No significant Grade 3/4 toxicities were experienced during or after treatment. Actual local control at 2 years was 87.5%. One patient died 1 month after radiotherapy secondary to massive epistaxis. The remaining 7 patients had progressive resolution of disease and were symptom-free at last follow-up. Persistent rhinitis was the only significant toxicity, seen in 1 patient. Conclusions: Conformal radiotherapy results in good local control with minimal acute and late side effects in juvenile nasopharyngeal angiofibromas, even in the presence of advanced disease.« less

Young offenders represent a group for which Chlamydia trachomatis infection screening is recommended in the US. In the absence of local epidemiological data it is difficult to assess whether such recommendations apply to the Swiss context. Our aim was to obtain local prevalence data for Chlamydia trachomatis infection among young male offenders as a basis for screening strategies in Swiss juvenile detention centres. This cross-sectional study was conducted in a juvenile detention facility in Geneva, Switzerland. Adolescent males aged 15-18 years admitted to the detention facility were invited to participate during a consultation with a nurse conducted within 48 hours of admission. Participants were asked to provide a first void urine sample for PCR detection of Chlamydia trachomatis infection and to complete a questionnaire on reproductive health behaviours. 72 males were considered for participation in the study. 13 were excluded (mainly due to the language barrier or a shorter than 3 days' stay in the facility) and 9 (15%) declined participation. Not being sexually active was the most common reason for declining participation. Most participants originated from Switzerland or the European Union and 68% reported having ≥2 sexual partners in the past year. Only one participant (18 years, asymptomatic) had Chlamydia trachomatis infection (2%; 95%CI: 0-6%). This study does not support screening for Chlamydia trachomatis among young offenders admitted to detention centres in Switzerland. Studies in other European detention centres should document the extent to which our findings are generalisable to the European context.

To study the major social-psychological factors contributing to male juvenile delinquency. One hundred and thirty-seven cases of male juvenile delinquents (delinquent group) and 145 aged-matched male students (control group) were enrolled in this case-control study. A questionnaire survey was conducted using the Adolescent Self-Rating Life Events Check List, the Coping Style Questionnaire, the Family Environment Scale-Chinese version, and the Social Support Rating Scale. The monovariate analysis showed that the total score and the scores of some factors of negative life events, the scores of immature coping styles and family conflicts, and the proportion of broken families in the delinquent group were significantly higher than those in the control group. In contrast, the scores of educational levels, study stress factor in the negative life events, mature coping styles, family environments and social supports were significantly lower in the delinquent group than those in the control group. The multivariate factors analysis showed that 7 variables were enrolled into the discriminatory equations, including negative life events (interpersonal relationship and healthy adaptation), self-condemn styles, family conflicts, subjective supports, objective supports, and utilization of social supports. The total accuracy of this equation was 92.2%. Negative life events in the interpersonal relationship and healthy adaptation, self-condemn styles, family conflicts, and weak social support system may be major social-psychological factors contributing to male juvenile delinquency.

In response to population declines of Burbot Lota lota maculosa, conservation aquaculture methods have been developed for this species. In general, Burbot are relatively resistant to many salmonid pathogens; however, cultured juvenile Burbot have experienced periodic epizootic disease outbreaks during production. A series of trials were conducted to determine the virulence of select bacteria isolated from juvenile Burbot following outbreaks that occurred in 2012 and 2013 at the University of Idaho's Aquaculture Research Institute. Initial clinical diagnostics and sampling resulted in the isolation of numerous putative bacterial pathogens. To determine which bacteria were the most likely causative agents contributing to these epizootics, juvenile Burbot were injectied intraperitoneally (IP) with select bacteria in log phase growth. Mortality associated with specific isolates was recorded, and more comprehensive challenges followed this initial screening. These challenges used side-by-side IP and immersion methods to expose Burbot to potential pathogens. The challenges resulted in significantly higher mortalities in fish following IP injection of two Aeromonas sp. isolates compared to controls (P ≤ 0.01), but no difference in mortality for immersion challenged groups was observed (P = 0.42). Results demonstrate that two isolates (Aeromonas sp.) cultured from the epizootics are virulent to Burbot. This article is protected by copyright. All rights reserved.

On the Pacific island of Guam, control of the invasive Brown Treesnake (Boiga irregularis) relies largely on methods that use mice as bait. Juvenile B. irregularis feed primarily on lizards and their eggs, but little is known about their prey preference. We conducted an experiment to investigate preferences for, and acceptance of, dead geckos, skinks, and neonatal mice, in juvenile B. irregularis ranging from 290 mm to ca. 700 mm snout-vent length (SVL). Snakes of all sizes showed a preference for geckos over skinks and neonatal mice. Geckos were the first prey chosen in 87% of 224 initial trials (56 snakes subjected to four trials each; 33% would be expected from a random choice). The smallest snakes had the most pronounced preference. Although many of the snakes accepted neonatal mice and/or skinks, some snakes of all sizes were reluctant to feed on anything but geckos, especially when well fed. We also addressed the hypothesis that repeated encounters with a particular prey type increase a snake's preference for that prey. Our study does not support this hypothesis. Our results suggest that control methods relying solely on rodent bait may be inefficient for targeting snakes < 700 mm SVL and that individual heterogeneity in prey preference may cause a significant part of this juvenile cohort to be completely refractory to capture with rodent bait, even if the bait is dead and small enough to be readily swallowed.

A number of studies have reported data suggestive of a significant association between ADHD and BPD, nevertheless, the nature of this relation has not been fully understood yet. In our study, we tried to evaluate if the relationship between retrospectively assessed ADHD symptoms and adult BPD features could mediated by selected temperament/personality traits. Four hundred forty-seven in- and outpatients consecutively admitted to the Clinical Psychology and Psychotherapy Unit of the Scientific Institute H San Raffaele of Milan, Italy, were administered the Italian versions of the following instruments: Structured Clinical Interview for DSM-IV Axis II Personality Disorders, Version 2.0 (SCID-II), Wender Utah Rating Scale (WURS), Temperament and Character Inventory-Revised (TCI-R), Barratt Impulsiveness Scale-11 (BIS-11), and Aggression Questionnaire (AQ). Our mediation analyses showed that the combination of impulsivity, aggression, novelty seeking, and juvenile conduct problems completely mediate the relationship between retrospectively assessed ADHD symptoms and current BPD features.

The runoff volumes in 2002 were near average for the January to July period above Lower Granite Dam (80%) and The Dalles Dam (97%). The year 2002 hydrosystem operations and runoff conditions resulted in flows that were less than the seasonal Biological Opinion (Opinion) flow objectives at Lower Granite Dam for both the spring and summer period. The seasonal flow objectives for Priest Rapids and McNary dams were exceeded for the spring period, but at McNary Dam summer flow objectives were not met. While seasonal flow objectives were exceeded for the spring at McNary Dam, the 2002 season illustrated thatmore » Biological Opinion management to seasonal flow targets can result in conditions where a major portion of the juvenile fish migration migrates in conditions that are less than the flow objectives. The delay in runoff due to cool weather conditions and the inability of reservoirs to augment flows by drafting lower than the flood control elevations, resulted in flows less than the Opinion objectives until May 22, 2002. By this time approximately 73% of the yearling chinook and 56% of steelhead had already passed the project. For the most part, spill in 2002 was managed below the gas waiver limits for total dissolved gas levels and the NMFS action criteria for dissolved gas signs were not exceeded. The exception was at Lower Monumental Dam where no Biological Opinion spill occurred due to the need to conduct repairs in the stilling basin. Survival estimates obtained for PIT tagged juveniles were similar in range to those observed prior to 2001. A multi-year analysis of juvenile survival and the factors that affect it was conducted in 2002. A water transit time and flow relation was demonstrated for spring migrating chinook and steelhead of Snake River and Mid Columbia River origin. Returning numbers of adults observed at Bonneville Dam declined for spring chinook, steelhead and coho, while summer and fall chinook numbers increased. However, all numbers were far greater than observed in the past ten years averaged together. In 2002, about 87 million juvenile salmon were released from Federal, State, Tribal or private hatcheries into the Columbia River Basin above Bonneville Dam. This represents an increase over the past season, when only 71 million juvenile fish were released into the same area.« less

BACKGROUND: Mood disorders have been described as the commonest psychiatric disorders in patients with temporal lobe epilepsy. Secondary depression in temporal lobe epilepsy could be interpreted either as an adjustment reaction to a chronic disease or as a limbic dysfunction. To clarify this issue, a controlled study of psychiatric disorders was conducted in different forms of epileptic and non-epileptic chronic conditions. METHODS: Twenty outpatients with temporal lobe epilepsy, 18 outpatients with juvenile myoclonic epilepsy--a primary generalised seizure disorder--20 matched type I diabetic patients, and 20 matched normal controls were assessed by a structured interview (SADS) and by self rating scales (Beck depression inventory (BDI) and the state and trait anxiety scales STAIX1 and STAIX2). RESULTS: Sixteen (80%) patients with temporal lobe epilepsy fulfilled the criteria for a psychiatric diagnosis at the SADS interview with a significantly higher frequency than patients with juvenile myoclonic epilepsy (22%) and diabetic patients (10%) (P < 0.0001). The most frequent disorder in temporal lobe epilepsy was a mood disorder: 11 (55%) patients with temporal lobe epilepsy had depression compared with three patients with juvenile myoclonic epilepsy and two diabetic patients (P < 0.001). Eight patients with temporal lobe epilepsy with an affective disorder also had a comorbid personality or anxiety disorder. Patients with temporal lobe epilepsy scored significantly higher on BDI, STAIX1, and STAIX2 than the three control groups (P < 0.001, P < 0.01, P < 0.001). CONCLUSIONS: Patients with temporal lobe epilepsy have a higher incidence of affective and personality disorders, often in comorbidity, than patients with juvenile myoclonic epilepsy and diabetic patients suggesting that these psychiatric disorders are not an adjustment reaction to a chronic disease but rather reflect a limbic dysfunction.

We conducted laboratory experiments with Dabry's sturgeon, Acipenser dabryanus, from the upper Yangtze River to develop a conceptual model of early behavior. We daily observed fish from day-0 (embryo, first life interval after hatching) to day-30 feeding larva for preference of bright habitat and cover, swimming distance above the bottom, up- and down-stream movement, and diel activity. Hatchling to day-12 embryos and days 13-24 larvae were similar for ontogenetic behavior, i.e., neither initiated a dispersal migration, both swam within 15 cm of the bottom, both preferred bright habitat, and neither strongly preferred cover or open habitat. Embryos and larvae were weakly active day and night. Days 72-76 juveniles had a weak nocturnal downstream migration, indicating wild juveniles disperse from a spawning site. In other sturgeon species yet studied representing three genera on three continents, Dabry's sturgeon is the first that does not disperse as an embryo or larva. Development of Dabry's sturgeon is slow, requiring more cumulative temperature degree days per millimeter of larvae TL than is required for other sturgeons to develop into larvae. Thus, a dispersal migration that diverts energy from development may not be adaptive. The available information suggests the initial dispersal of early life intervals is likely done by females, which spawn in a dispersed spawning style, not the usual aggregated spawning style. Juvenile migrants had a black body and tail with a light line along the lateral scutes. The color of juvenile migrants shows that a dark body and tail is characteristic of Acipenser that migrate downstream as larvae or juveniles.
