    This study examines the effectiveness of social support networks on psychological well-being among 602 homeless and runaway adolescents. The respondents were interviewed in shelters, drop-in centers, and on the streets in cities of four Midwestern states (Missouri, Iowa, Nebraska, and Kansas). The path model was used to test the direct effect of family abuse and precocious independence on adolescent depressive symptoms and indirect effects through social support networks. Results indicate that although abusive family origins contribute directly to depressive symptoms there are indirect effects of family abuse and early independence through social support networks. Family abuse and early independence drive homeless adolescents to rely on peers for social support. While support from friends on the street reduces depression, association with deviant peers increases depression.

    2011-11-01

    Little is known about the prevalence of violent behaviors among homeless and runaway adolescents or the specific behavioral factors that influence violent behaviors across time. In this longitudinal study of 300 homeless and runaway adolescents aged 16-19 years at baseline, we use event history analysis to assess the factors associated with acts of violence over three years, controlling for individual propensities and time-varying behaviors. The results indicate that females, non-minorities, and non-heterosexuals were less likely to engage in violence across time. Those who met criteria for substance abuse disorders (i.e. alcohol abuse, alcohol dependence, drug abuse) were more likely to engage in violence. A history of caretaker abuse was associated with violent behaviors, as were street survival strategies such as selling drugs, participating in gang activity, and associating with deviant peers. Simply having spent time directly on the streets at any specific time point also increased the likelihood for violence.

    To study differences between runaways and non-runaways in a mental health clinic and to study differences between runaways in a mental health clinic and legal / shelter system. Psychiatric records of runaways and non-runaways from Vajira Hospital were collected from June 1994 to October 2003. 21 cases in each group were studied in various factors. 21 runaway cases who were in child and adolescent shelters were interviewed by the researchers. Neglect, sexual abuse, rejection, poverty and truancy were more common in the runaway group. The runaway group had more conduct disorder and substance abuse. Physical abuse, authoritarian and being in custody were more common in runaways in shelters. Various factors correlate with running away. These factors lie beneath long before runaway has taken place and understanding and managing them help in preventing and prompt treatment.

    Objectives To analyze the trend of dextromethorphan abuse in California and to compare these findings with national trends. Design A 6-year retrospective review. Setting California Poison Control System (CPCS), American Association of Poison Control Centers (AAPCC), and Drug Abuse Warning Network (DAWN) databases from January 1, 1999, to December 31, 2004. Participants All dextromethorphan abuse cases reported to the CPCS, AAPCC, and DAWN. The main exposures of dextromethorphan abuse cases included date of exposure, age, acute vs long-term use, coingestants, product formulation, and clinical outcome. Main Outcome Measure The annual proportion of dextromethorphan abuse cases among all exposures reported to the CPCS, AAPCC, and DAWN databases. Results A total of 1382 CPCS cases were included in the study. A 10-fold increase in CPCS dextromethorphan abuse cases from 1999 (0.23 cases per 1000 calls) to 2004 (2.15 cases per 1000 calls) (odds ratio, 1.48; 95% confidence interval, 1.43–1.54) was identified. Of all CPCS dextromethorphan abuse cases, 74.5% were aged 9 to 17 years; the frequency of cases among this age group increased more than 15-fold during the study (from 0.11 to 1.68 cases per 1000 calls). Similar trends were seen in the AAPCC and DAWN databases. The highest frequency of dextromethorphan abuse occurred among adolescents aged 15 and 16 years. The most commonly abused product was Coricidin HBP Cough & Cold Tablets. Conclusions Our study revealed an increasing trend of dextromethorphan abuse cases reported to the CPCS that is paralleled nationally as reported to the AAPCC and DAWN. This increase was most evident in the adolescent population. PMID:17146018

    2013-07-01

    Shelter-recruited adolescents are known to have high rates of substance abuse and co-occurring internalizing and externalizing problem behaviors. Many studies have documented these mental health concerns, but only a small number of studies have tested interventions that may be useful for ameliorating these vulnerabilities. The current study compared three empirically supported psychotherapy interventions, Motivational Interviewing (MI), the Community Reinforcement Approach (CRA), and Ecologically-Based Family Therapy (EBFT) with 179 substance abusing runaway adolescents (47 % female, 74 % minority) and their primary caretaker recruited through a Midwestern runaway crisis shelter. Examining both child and primary caretaker reports, each treatment was associated with significant reductions in internalizing and externalizing behaviors to 24 months post-baseline. However, the trajectory of change differed among the treatments. Adolescents receiving MI showed a quicker reduction in internalizing and externalizing behaviors but also a quicker increase in these behaviors compared to adolescents receiving EBFT, who continued to evidence improvements to 24 months. The findings provide support for continued evaluation of these treatments for use with this vulnerable population of adolescents.

    2008-08-01

    Homeless youth are at particularly high risk for teen pregnancy; research indicates as many as 20% of homeless young women become pregnant. These pregnant and homeless teens lack financial resources and adequate health care, resulting in increased risk for low-birth-weight babies and high infant mortality. This study investigated individual and family-level predictors of teen pregnancy among a national sample of runaway/homeless youth in order to better understand the needs of this vulnerable population. Data from the Runaway/Homeless Youth Management Information System (RHY MIS) provided a national sample of youth seeking services at crisis shelters. A sub-sample of pregnant females and a random sub-sample (matched by age) of nonpregnant females comprised the study sample (N = 951). Chi-square and t tests identified differences between pregnant and nonpregnant runaway females; maximum likelihood logistic regression identified individual and family-level predictors of teen pregnancy. Teen pregnancy was associated with being an ethnic minority, dropping out of school, being away from home for longer periods of time, having a sexually transmitted disease, and feeling abandoned by one's family. Family factors, such as living in a single parent household and experiencing emotional abuse by one's mother, increased the odds of a teen being pregnant. The complex problems associated with pregnant runaway/homeless teens create challenges for short-term shelter services. Suggestions are made for extending shelter services to include referrals and coordination with teen parenting programs and other systems of care.

    Williams, Robert J; Goodale, Leslie A; Shay-Fiddler, Michele A; Gloster, Susan P; Chang, Samuel Y

    2004-01-01

    The prevalence of methylphenidate and dextroamphetamine misuse and abuse was examined in 450 adolescents referred for substance abuse treatment. Twenty three percent reported nonmedical use of these substances and six percent were diagnosed as methylphenidate or dextroamphetamine abusers. Abuse was more common in individuals who were out of school and had an eating disorder. Methylphenidate and dextroamphetamine abuse appears to be much less common than abuse of most other substances. It does occur, however, and parents and schools need to exert greater control over the dispensing of these medications. Physicians are advised to prescribe non-stimulant medications (eg, bupropion) when treating attention deficit hyperactivity disorder in substance-abusing individuals.

    2017-02-01

    Internal short circuit of large-format Li-ion pouch cells induced by mechanical abuse was simulated using a modified mechanical pinch test. A torsion force was added manually at ∼40% maximum compressive loading force during the pinch test. The cell was twisted about 5° to the side by horizontally pulling a wire attached to the anode tab. The combined torsion-compression force created small failure at the separator yet allowed testing of fully charged large format Li-ion cells without triggering thermal runaway. Two types of commercial cells were tested using 4-6 cells at each state-of-charge (SOC). Commercially available 18 Ahr LiFePO4 (LFP) and 25 Ahr Li(NiMnCo)1/3O2 (NMC) cells were tested, and a thermal runaway risk (TRR) score system was used to evaluate the safety of the cells under the same testing conditions. The aim was to provide the cell manufacturers and end users with a tool to compare different designs and safety features.

    2006-09-01

    The objective of this article is to review the state of the science in evidence-based drug abuse treatments for Hispanic adolescents, highlight scientific opportunities, and offer recommendations to further the field of drug abuse treatment for this population. The article is divided into seven sections: boundaries for this review, drug abuse and associated problems, behavioral treatment, cultural issues in hispanic adolescent behavioral drug abuse treatment, pharmacological treatment, gender differences in treatment, and scientific opportunities/recommendations. Although only one treatment approach, Brief Strategic Family Therapy, has been empirically shown to be efficacious in treating Hispanic adolescent drug abusers, with some modifications other treatments may also have the potential to be efficacious with Hispanic adolescents. Family-based approaches, which typically appear to be most efficacious with adolescents in general, may also have the greatest potential to treat drug abuse in Hispanic adolescents.

  4. Psychologic aspects of sexual abuse in adolescence.

    Jeffrey, T B; Jeffrey, L K

    1991-12-01

    This paper reviews psychologic aspects of sexual abuse in female adolescents. It documents that sexual abuse is widespread, occurring at an alarming rate at all socioeconomic levels of society. It is perpetrated principally by adult men in the victim's family. Often its effects are tragic. Adolescent female sexual abuse victims are at high risk for subsequent acting out behavior, sexual promiscuity, physical and sexual abuse, anxiety, depression, low self-esteem, alcohol and drug abuse or dependence, chronic sleep disturbance, dissociative disorders, eating disorders, emotional numbing, dissociation, guilt, shame, hyperalertness, suicidal ideation, and multiple associated psychiatric disorders. Although it may appear at a surface level that sexual abuse victims recover from such abuse, follow-up studies suggest that many remain disabled long after the abuse has ended. Health care professionals should be especially cognizant of the magnitude of the impact of sexual abuse on adolescent girls and recognize the need of these patients for psychologic and medical services.

    1991-01-01

    Problems related to homeless/runaway youths have received increased attention in recent years. Homeless/runaway youths manifest many problems in addition to being absent from home and without supervision of a parent or guardian. The purpose of the study was to determine drug use and abuse patterns of homeless/runaway youths and to compare those patterns, along with attitudes toward selected illicit behaviors, with similar data collected from adolescents in school. Data were collected from persons (n = 253) in homeless/runaway shelters in the southeast United States. Comparisons made with data from other studies of runaways and of youths in school indicate that drug use and abuse is two-three times more prevalent for runaways than with the school youths. Runaways' attitudes toward selected illicit behaviors are more tolerant than those of school youths. Intervention programs for runaway/homeless youths should reflect an understanding of the complexity of the psycho-social and behavioral history of the clients which is much different than that of those who are in school.

    Boyce, Cheryl Anne; Lynne-Landsman, Sarah D

    2013-06-01

    Adolescence is an exciting and challenging period of maturation, rapid brain development, and developmental changes in neurobiological, neurocognitive, and neurobehavioral processes. Although behavioral therapies available for adolescent substance abuse have increased, effectiveness research in this area lags considerably behind that of clinical research on treatment for drug-abusing adults. Behavioral treatment approaches show significant promise for treating drug-abusing adolescents, but many have not incorporated innovations in neuroscience on brain development, cognitive processes, and neuroimaging. Linking developmental neuroscience with behavioral treatments can create novel drug abuse interventions and increase the effectiveness of existing interventions for substance-abusing adolescents. Contemporary research on brain development, cognition, and neuroscience is ripe for translation to inform developmentally sensitive drug abuse treatments for adolescents. Neuroscientists and interventionists are challenged to build mutual collaborations for integration of neuroscience and drug abuse treatment for adolescents.

    Tramadol abuse liability is underestimated and the evidence of abuse and dependence is emerging. It has many health and social consequences especially in adolescents. Tramadol abuse has not been well studied in Egypt. The aim of this study was to estimate the prevalence and associated correlates of tramadol use and abuse among school students in Egypt. A total of 204 students, aged 13-18 years, from six schools in Zagazig, Egypt, were screened for tramadol use using The Drug Use Disorders Identification Test and a urine screen for tramadol. The prevalence of tramadol use was 8.8% among school students and the average age at onset of tramadol use was 16.5 ± 1.1. Some 83% of the users were using tramadol alone while the rest (17%) were using a combination of tramadol, alcohol, and cannabis. Two-thirds of these students started with tramadol as the first drug after the onset of tobacco smoking. Over one third of tramadol users had drug-related problems and 6% had dependence. There was a significant association between tramadol use and older age, male gender, and smoking. Drug-related problems were negatively correlated with age at onset of tramadol use. Tramadol use was common among adolescents and over one third of tramadol users had drug-related problems. Population-based longitudinal studies are needed to investigate tramadol use and the possible role of tramadol as a gateway drug in the development of substance abuse in Egypt.

    Full Text Available This article came from the monographic study “Resilience and Sexual Violence: a study of adolescents victimized by sexual abuse assistance” (MARANHÃO, 2008, in which was investigated the building resilience in victimized adolescents. Resilience is characterized as overcoming adversity, setting up as something procedural, promoted by the interaction of personal and collective protection, in particular context of risk or social vulnerability. We made the trimming about the meanings and feelings of sexual victimization within the family from the perception of adolescents between 12 and 16 years of age that received care in a Specialized Reference Social Assistance in 2010. The research is qualitative, having as theoretical-methodological referential the Historic-Cultural Theory. Data collection was used by semi-structured interview. We realize that the profile of the victims are set up by females, the beginning of sexual abuse occurred between childhood and preadolescence. The profile of perpetrators are men, adults, acting the role of the stepfather, father and uncle. Despite an abject sense, adolescents could not break the cycle of violence. Friends, extended family, and the work of professionals emerged as support for the redefinition of the abusive relationships.

    Empirical evidence has revealed various factors that contribute to the development and maintenance of Internet abuse. The aim of this paper was to analyze, on a sample of Spanish adolescents, the relationship between Internet abuse and: (1) Personal and interpersonal risk factors, including social skills in both virtual and real-life contexts; (2) Drug use. A total of 814 high school students aged between 13 and 17 participated in this study, and were divided into two groups: Internet Abusers (IA = 173) and Non-Internet Abusers (NIA = 641). Questionnaires were used to analyze Internet and drug use/abuse, as well as social skills, in virtual and real contexts. Various interpersonal risk factors (family and group of friends) were also assessed. IA showed a more severe pattern of Internet and drug use, as well as poorer social skills in both contexts. Moreover, their groups of friends appeared more likely to become involved in risky situations related to Internet and drug abuse. Both IA and NIA showed more adaptive social skills in the virtual context than in the real one. There is a need for further research to build on these findings, with a view to designing specific preventive programs that promote responsible Internet use.

Factor analysis of quantitative data revealed 3 factors attributed to main clinical types of alcohol abuse in adolescents: 1) alcohol abuse associated with personal disorders; 2) alcohol abuse associated with attention deficit hyperactivity disorder - ADHD; 3) alcohol abuse associated with the sensitivity within personal-neurotic reactions.

  1. Sexual abuse of children and adolescents.

    Science.gov (United States)

    Sugar, M

    1983-01-01

    Parents, relatives, and friends may inflict their passions on children of the same or opposite sex. This is often initiated by sleeping together. Sexual abuse contributes to and causes emotional trauma, although the child's turmoil, confusion, wish for acceptance, and anxiety may be overlooked by the parent and professional. Mutual silence aided by threats adds to the anxiety. Despite the notion that reports of parental sexual exploitation of their children are usually fantasies, there appear to be increasing data that incest and sexual abuse are frequent traumata. At present, there is increased risk of lowering the incest barrier because of increased rates of divorce and step- or surrogate parenthood, since they provide additional potential for being sexually and emotionally traumatized. Sexual abuse seems to be part of a constellation involving neglect and a pathological symbiosis. That sexual abuse is emotionally traumatic is apparent, but it needs emphasizing. Children's defensive reactions may cloud this, and it may be years before such incidents are connected to symptomatic behavior, even when the child is in intensive therapy. In the reported cases, there appears to be a pattern of reactions and defenses related to the traumata that are embedded in imprinting and identification with the aggressor. This leads to sexual abuse being a legacy passed on to the next generation of victims, as the victim becomes the molester through identification. Adolescent self-destructive behavior may stem from guilt about sexually abusing younger children. Therapists may be better able to understand and deal with some of their patients' symptoms if sexual abuse is considered as a possible factor in one or both directions.

    2017-01-01

    This cross-sectional, case control study examines the association between child sexual abuse and interpersonal and intrapersonal outcomes among 54 adolescents, examining specific clinical measures (depression, anxiety, dissociation, and posttraumatic stress disorder, attachment patterns, self-esteem, self-disclosure, and family environment characteristics). The research results point to a correlation between sexual abuse and higher levels of the clinical measures. In addition, a correlation was found between sexual abuse and level of avoidant attachment, self-esteem, and family environment characteristics. Stepwise hierarchical regressions were conducted to examine how adolescent attributes predicted depression, anxiety, and dissociation beyond the prediction based on sexual abuse. A combination of self-esteem, anxiety attachment, and family cohesiveness made sexual abuse insignificant when predicting levels of depression, anxiety, and dissociation. This study contributes to characterizing the emotional, personal, and family attributes of adolescents who experienced sexual abuse. It also raises questions about the clinical outcomes usually associated with sexual abuse.

    To assess the prevalence and frequency of medical marijuana diversion and use among adolescents in substance abuse treatment and to identify factors related to their medical marijuana use. This study calculated the prevalence and frequency of diverted medical marijuana use among adolescents (n = 164), ages 14-18 years (mean age = 16.09, SD = 1.12), in substance abuse treatment in the Denver metropolitan area. Bivariate and multivariate analyses were completed to determine factors related to adolescents' use of medical marijuana. Approximately 74% of the adolescents had used someone else's medical marijuana, and they reported using diverted medical marijuana a median of 50 times. After adjusting for gender and race/ethnicity, adolescents who used medical marijuana had an earlier age of regular marijuana use, more marijuana abuse and dependence symptoms, and more conduct disorder symptoms compared with those who did not use medical marijuana. Medical marijuana use among adolescent patients in substance abuse treatment is very common, implying substantial diversion from registered users. These results support the need for policy changes that protect against diversion of medical marijuana and reduce adolescent access to diverted medical marijuana. Future studies should examine patterns of medical marijuana diversion and use in general population adolescents. Copyright © 2012 American Academy of Child and Adolescent Psychiatry.

    This study focuses on family predictors of conflict behavior in adolescent dating relationships, drawing on family systems and socialization perspectives. Mother-adolescent, father-adolescent, and triadic relationships each was examined as predictors of adolescent dating outcomes that hold importance for developmental and prevention science (positive conflict resolution, verbal abuse, and physical abuse). We conducted a longitudinal analysis using a 6-month longitudinal design with 236 ethnically diverse high school students. Findings indicate that triangulation into parental conflicts was related to increases in positive conflict resolution and with increases in verbally abusive behavior with dating partners over time. Parent-adolescent closeness and conflict each was related to positive conflict resolution and verbal abuse, but these associations were only found for boys. © 2015 The Authors.

    To describe the knowledge, attitudes, and behaviors of runaway and homeless youths regarding infection with the human immunodeficiency virus (HIV). Cross-sectional, descriptive. A crisis shelter for runaway and homeless youths. One hundred one residents, aged 13 to 20 years, of a shelter for homeless and runaway youths in Houston, Tex. None. A self-administered questionnaire was used to examine the knowledge, attitudes, and behaviors of these youths regarding infection with HIV. Nearly one fourth had injected illegal drugs; one fifth had shared needles for other purposes. Sixteen percent had had anal intercourse, 19% had engaged in prostitution, and 67% of all subjects reported having four or more sexual partners. One fifth reported that they always use condoms. While quite knowledgeable about means of transmission, they held prevalent misconceptions about casual contact and risk reduction. Youths perceive few barriers to condom use, have fairly high intentions to practice preventive behavior, and have high self-efficacy to do so. Most believe they are at little or no risk for acquiring HIV. These findings support the need for medical, educational, and social service programs to reduce the risk of HIV among these youths. Runaway and homeless youths practice behaviors that place them at high risk for acquisition of HIV infection. Risk reduction is imperative and will require programs that address the educational, psychological, social, and medical needs of these youths.

    2008-01-01

    Full Text Available Introduction: Narcotic drug abuse and illicit use of drugs is a major, complicated multifactorial phenomenon affecting most of the societies today. Incidence of drug abuse among adolescents is very high. Adolescents become addicted to substances more quickly than adults. The aim of this study was to assess the pattern of drug abuse among male adolescents in Hamadan. Methods: This study was a descriptive study and samples (n=400 were collected on the basis of snowball sampling method. Information was collected individually through completion of a researcher-designed questionnaire including demographic and epidemiological indices, perceived familial support, religiosity, and locus of control. Results: The results showed that smoking (93%, alcohol (92.5%, marijuana (64.3%, and opium (57.8% use were very high, while LSD (4.8% and Cocaine(2.3% use was rare. 77.8 % of adolescents began drug abuse between 12 and 18 years of age. Moreover, sensation seeking (26.5%, individual interest (24.8%, and peer pressure (22%, were the main reasons for drug abuse. Conclusion: As initial smoking, alcohol and marijuana use play an important role in determining the future addiction of adolescents to narcotics, yearly surveillance programs in the country and evaluation of etiological factors of narcotic addiction need to be studied carefully. All of the preventive and school programs designed for the young should take into account environmental, demographic and policy factors in addition to personal factors so that the programs have a maximum effect.

    A long-standing belief in the literature on sex offenders is that sexually victimized youths are at increased risk of becoming sex offenders themselves. The present study tested the link between past sexual abuse, either with or without contact, and sexually offending behavior in a representative sample of male and female adolescents while controlling for other types of abuse, mental health problems, substance use, and non-sexual violent behaviors. Self-reported data were collected from a nationally representative sample of 6,628 students attending 9th grade public school in Switzerland (3,434 males, 3,194 females, mean age = 15.50 years, SD = 0.66 years). Exposure to contact and non-contact types of sexual abuse was assessed using the Child Sexual Abuse Questionnaire and sexually offending behavior by the presence of any of three behaviors indicating sexual coercion. Two-hundred-forty-five males (7.1 %) and 40 females (1.2 %) reported having sexually coerced another person. After controlling for non-sexual abuse, low parent education, urban versus rural living, mental health problems, substance use, and non-sexual violent behavior, male adolescents who were victims of contact sexual abuse and non-contact sexual abuse were significantly more likely to report coercive sexual behaviors. Females who experienced contact or non-contact sexual abuse were also found at increased risk of committing sexual coercion after controlling for covariates. The present findings demonstrate a strong relationship between past sexual abuse, with and without physical contact, and sexual-offending behavior in male and female adolescents. Reducing exposure to non-contact sexual abuse (like Internet-based sexual exploitation) should become a new area of sexual violence prevention in youths.

    Substance abuse is one of the nation's primary health concerns. Native American youth experience higher rates of substance abuse than other youth. There is little empirical evidence that exists concerning the use of culturally-based interventions among Native American adolescents. This study used a community-based participatory research approach to develop and evaluate an innovative school-based cultural intervention targeting substance abuse among a Native American adolescent population. A two-condition quasi-experimental study design was used to compare the Cherokee Talking Circle (CTC) culturally-based intervention condition (n = 92) with the Be A Winner Standard Education (SE) condition (n = 87). Data were collected at pre-intervention, immediate post-intervention, and 90-day post-intervention using the Cherokee Self-Reliance Questionnaire, Global Assessment of Individual Needs - Quick, and Written Stories of Stress measures. Significant improvements were found among all measurement outcomes for the CTC culturally-based intervention. The data provide evidence that a Native American adolescent culturally-based intervention was significantly more effective for the reduction of substance abuse and related problems than a noncultural-based intervention. This study suggests that cultural considerations may enhance the degree to which specific interventions address substance abuse problems among Native American adolescents.

    Full Text Available Inhalant abuse has been commonly reported especially in the young during the last decades globally. The reason for the relative paucity of literature from India may be attributed to a lack of knowledge about this growing problem among health professionals. A series of five cases of inhalant abuse is described in order to understand this growing public health concern. Most of the cases started inhalant abuse during adolescence. All patients except one abused typewriter erasing fluid and thinner which contains toluene. All the patients reported using inhalants as addictive substance because of their easy accessibility, cheap price, their faster onset of action and the regular ′high′ that it provided. Whereas several features of inhalant dependence were fulfilled, no physical withdrawal signs were observed. The diagnosis of inhalant abuse can be difficult and relies almost entirely on clinical judgment. Treatment is generally supportive.

    2012-04-01

    Research on the correspondence between adolescent and parent reports of adolescent substance abuse has typically been conducted on adolescent outpatient treatment samples, or on non-treatment samples. In the current study, fifty adolescents receiving residential substance abuse treatment, and their parents were assessed separately regarding the teen's substance use (e.g., cigarettes, alcohol, marijuana, other illicit drugs) during the 90 days preceding adolescent treatment entry. Correspondence between reporters was for the most part fair to excellent, with observed discrepancies generally due to parents providing lower estimates of use than did adolescents. Multiple regression analysis revealed that higher discrepancy between reporters occurred when the parent was younger, when the parent encountered fewer problems due to the teen's substance use, when the adolescent attended more probation or parole meetings, the fewer the number of days the adolescent was incarcerated, and the fewer days the adolescent lived at home prior to treatment. Results from exploratory analyses suggest that parents and adolescents are more discrepant when the assessment occurs later in the adolescent's treatment program. Overall, results suggest that in the absence of a cooperative teen, parental report of the adolescent's previous substance use could serve as a good proxy among families in which the adolescent is entering residential substance abuse treatment.

    Introduction The purpose of this study was to investigate the psychiatric consequences of sexual abuse and its associated factors in children and adolescents referred to our child and adolescent psychiatry clinic from official medico–legal units. Methods All victims of sexual abuse (n=590) aged 1–18 (mean: 13.56±3.38) referred from forensic units to Ondokuz Mayis University Child and Adolescent Psychiatry Clinic over a period of 2 years [boys: 83 (14.1%); girls: 507 (85.9%)] were included. Child and adolescent psychiatry and forensic medicine specialists evaluated all the cases. The Wechsler Intelligence Scale for Children-Revised Form (WISC-R) and the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version-Turkish Version (K-SADS-PL-T) were applied. Results Abuse-related psychiatric diagnoses (of which 45.9% were major depressive disorder and 31.7% were post-traumatic stress disorder cases) were made in 75.2% of the cases. In 80.3% of the cases, the perpetrators were known to their victims [incest, n=91 (15.1%)], and intercourse took place in 48.8%. Although gender and age were not significantly associated with the appearance of any psychiatric disorders, severity of abuse (e.g., intercourse; p=.006), additional physical assault (pabuse severity, incest, involvement of any other victim, additional physical assault, and length of time from first abuse to first psychiatric evaluation. This combination of variables (occurrence of incest, additional physical assault, and a long duration from first abuse to first psychiatric evaluation) significantly predicted the appearance of a psychiatric disorder of any kind (χ2=55.42; df=7; n=522; pabuse to first psychiatric evaluation predict higher rates of sexual abuse-related psychiatric disorders.

    Full Text Available The research aimed to investigate the phenomena of adolescent depressive symptomology, substance abuse and the relationship between the two phenomena in a South African context. The influence of moderator variables was also examined. Another objective was to determine risk factors for the before mentioned. This was done by using a questionnaire with a sample of 1298 conveniently selected adolescents in a South African high school. It was determined that adolescents become progressively unhappier from 13 to 17 years of age. Girls are more depressed than boys. This research also revealed that adolescent depressive symptomology is significantly and positively correlated with earlier age of onset of substance abuse as well as frequency of usage. There appear to be no gender differences in substance abuse but teenagers from different ethnic and language groups differ in their use of substances. Risk factors for depression and substance abuse included a conflict relationship with parents, the experience of major stressful events, dissatisfaction with school grades and friends’ use of substances.

    Full Text Available Background Child abuse is a serious social health problem all over the world with important adverse effects. Objectives The aim of this study was to extend our understanding of the relation between mental disorders and child abuse. Materials and Methods The study was designed as a cross-sectional survey on 700 students in secondary schools using multiple cluster sampling in Yazd, Iran in 2013. We applied 2 self reported questionnaires: DASS (depression anxiety stress scales-42 for assessing mental disorders (anxiety, stress and depression and a standard self-reported valid and reliable questionnaire for recording child abuse information in neglect, psychological, physical and sexual domains. The collected data was analyzed using SPSS software. P-values < 0.05 were considered as significant. Results There was a statically significant correlation between mental disorder and child abuse score (Spearman rho: 0.2; P-value < 0.001. The highest correlations between mental disorders and child abuse were found in psychological domain, Spearman’s rho coefficients were 0.46, 0.41 and 0.36 for depression, anxiety and stress respectively (P-value < 0.001. Based on the results of logistic regression for mental disorder, females, last born adolescents and subjects with drug or alcohol abuser parents had mental disorder odds of 3, 0.4 and 1.9 times compared to others; and severe psychological abuse, being severely neglected and having sexual abuse had odds 90, 1.6 and 1.5 respectively in another model. Conclusions Programming for mandatory reporting of child abuse by physicians and all health care givers e.g. those attending schools or health centers, in order to prevent or reduce its detrimental effects is useful and success in preventing child abuse could lead to reductions in the prevalence of mental disorders.

    NMDA receptor antagonists include the prescription medication ketamine, the illicit xenobiotics PCP, MXE, and other novel PCP analogs, and the OTC medication DXM. The NMDA receptor antagonist most commonly abused by adolescents in the United States is DXM. These xenobiotics cause dissociative effects by non-competitively inhibiting the action of glutamate at the NMDA receptor. Additionally, these agents modulate the actions of monoamine neurotransmitters, agonize opioid receptors, and inhibit nitric oxide synthase. Patients typically present with sympathomimetic and neuropsychiatric clinical manifestations after abuse of NMDA receptor antagonists. Treatment is generally symptomatic and supportive. Interventions include benzodiazepines, propofol, fluids, antiemetics, aggressive cooling, and respiratory support.

    Baumrind, D; Moselle, K A

    1985-01-01

    Adolescent drug use is placed in an historical and developmental perspective. Existing evidence concerning causes and consequences of adolescent drug use is inconclusive. In the absence of conclusive empirical evidence and cogent theories, we present a prima facie case against early adolescent drug use by defending six propositions which posit specific cognitive, conative, and affective negative consequences including impairment of attention and memory; developmental lag imposing categorical limitations on the level of maximum functioning available to the user in cognitive, moral and psychosocial domains; amotivational syndrome; consolidation of diffuse or negative identity; and social alienation and estrangement. We call for a program of research which could provide credible evidence to support or rebut these propositions, and thus address the factual claims underlying the sociomoral concerns of social policy planners.

    A large number of adolescents in a psychiatric population, particularly those who are chemically dependent, prefer to listen to heavy metal music. Young people who do not identify with traditional values may find simple but unconventional answers to complex problems in the lyrics of this type of music. While a clearcut relationship cannot be established between heavy metal music and destructive behavior, evidence shows that such music promotes and supports patterns of drug abuse, promiscuous sexual activity, and violence.

    While research has explored adolescents' use of technology to perpetrate dating violence, little is known about how traditional in-person and cyber abuse are linked, and no studies have examined their relationship over time. Using our sample of 780 diverse adolescents (58 % female), we found that traditional and cyber abuse were positively associated, and cyber abuse perpetration and victimization were correlated at each time point. Cyber abuse perpetration in the previous year (spring 2013) predicted cyber abuse perpetration 1 year later (spring 2014), while controlling for traditional abuse and demographic variables. In addition, physical violence victimization and cyber abuse perpetration and victimization predicted cyber abuse victimization the following year. These findings highlight the reciprocal nature of cyber abuse and suggest that victims may experience abuse in multiple contexts.

    2010-02-01

    Full Text Available Abstract Doping with endocrine drugs is quite prevalent in amateur and professional athletes. The World Anti-Doping Agency (WADA has a list of banned drugs for athletes who compete and a strategy to detect such drugs. Some are relatively easy, anabolic steroids and erythropoietin, and others more difficult, human growth hormone (rhGH and insulin like growth factor I (IGF-I. The use of such compounds is likely less in adolescent athletes, but the detection that much more difficult given that the baseline secretion of the endogenous hormone is shifting during pubertal development with the greatest rise in testosterone in boys occuring about the time of peak height velocity and maximal secretion of hGH and IGF-I. This review notes the rationale, physiology, performance enhancement, adverse events and the detection of doping with insulin, rhGH, rhIGF-I, erythropoietin, and anabolic-androgenic steroids.

    Full Text Available Objective: Verify the occurrence of child and adolescent abuse referred to Caruaru Tutelary Council between 2002 and 2004. Method: To this end, data on the complaints lodged in the period concerned was requested from the Tutelary Council. Results: From a total of 798 cases reported the most common was neglect (49.24% followed by psychological violence (28.94%. Physical and sexual abuse represented 17.6% and 4.66% of the total of the sample, respectively. As to sex, males represented 55.3% of the cases reported. Conclusion: According to literature, lesions are most frequent on the orofacial area. The awareness of such a piece of information makes a high demand for dental surgeons´ ethical and legal responsibility. Besides reporting suspect child abuse to authorities, there is now a call for creating protective mechanisms for the abused in addition to preventive educational campaigns with focus on the need for denouncing and avoiding all kinds of maltreatment.

Results: In the Active group, 26% of mothers had completed high-school and 11% belonged to the A/B socioeconomic classes. The TD group showed the highest percentages of wage earning parents (52% living together (64%. In the WIRL group, 17% of the mothers were illiterate or had not completed primary education, and 23% of the fathers were unemployed. In the WI group, 22% lived in houses that had been lent to them. Conclusions: Results indicate the impact of addiction and underprivileged conditions (such as housing status, fathers’ level of education, and socioeconomic status on retention in the service and the importance of health prevention and promotion strategies aimed at this population.

  7. Child physical and sexual abuse and cigarette smoking in adolescence and adulthood.

    Science.gov (United States)

    Kristman-Valente, Allison N; Brown, Eric C; Herrenkohl, Todd I

    2013-10-01

    Analyses used data from an extended longitudinal study to examine the relationship between childhood physical and sexual abuse (CPA and CSA, respectively) and adolescent and adult smoking behavior. Two questions guided the study: (1) Is there an association between childhood abuse and adolescent and adult smoking behavior? (2) Does the relationship between childhood abuse and later cigarette smoking differ for males and females? A censored-inflated path model was used to assess the impact of child abuse on adolescent and adult lifetime smoking prevalence and smoking frequency. Gender differences in significant model paths were assessed using a multiple-group approach. Results show no significant relation between CPA or CSA and risk of having ever smoked cigarettes in adolescence or adulthood. However, for males, both CPA and CSA had direct effects on adolescent smoking frequency. For females, only CSA predicted increased smoking frequency in adolescence. Adolescent smoking frequency predicted adult smoking frequency more strongly for females compared with males. CPA and CSA are risk factors for higher frequency of smoking in adolescence. Higher frequency of cigarette smoking in adolescence increases the risk of higher smoking frequency in adulthood. Results underscore the need for both primary and secondary prevention and intervention efforts to reduce the likelihood of childhood abuse and to lessen risk for cigarette smoking among those who have been abused.

    normal intelligence adolescents with behavioral disorders. Risk factors that increase the chances of developing either simple or more complicated types of psychopathology in adolescents with mental retardation have been found to be based on individual, family and social levels. On the other hand, the individual characteristics of adolescents (intellectual level, attention capacity, understandable linguistic expression, overall progress until adolescence), the existence of a supportive family environment and the presence of social support and awareness through the creation of special counseling, education and medical services, are the most important protective factors which contribute to the prevention of several forms of psychopathology in adolescents with mental retardation. For the writing of the literature review, the following electronic databases were used: PubMed, Scopus, Psycinfo, Cochrane Library, Web of Science and Google Scholar. The key words used were: Intellectual Disability, Behavioral disorders, Adolescents, Mental Retardation, Learning disabilities, Developmental Disabilities, Disruptive behaviour disorders, Conduct disorder, Substance Abuse, Substance Misuse, Oppositional defiant disorder, Alcohol and illicit drug use, Smoking Use, Young people, Teenagers, Youths.

    Jones, Diana L; Heflinger, Craig Anne; Saunders, Robert C

    2007-12-01

    This paper presents an ecological-community model toward the explanation of variation in patterns of substance abuse (SA) service utilization among adolescents who are enrolled in Tennessee's Medicaid program (TennCare). Guided by a theoretical framework that draws from the social ecology work of Bronfenbrenner and health services utilization models promoted by Aday and Andersen, we apply a social indicators approach toward explaining the impact of community ecology on identification of SA and treatment engagement. Both county-level rates and individual-level treatment utilization are examined and hierarchical linear modeling is incorporated to examine the individual-in-community phenomenon. This study is an expansion of previous service utilization research and suggests that explanations of youth's service utilization must necessarily include not only individual, familial, and service system characteristics, but community factors, as well.

    2010-01-01

    Policy makers and advocates are increasingly encouraging child-serving organizations to work together. The current study examined how child welfare agency ties with substance abuse treatment providers and schools correlated with substance abuse treatment for adolescents receiving child protective services. A sample of adolescents with substance use risk was extracted from a national survey of families engaged with child welfare. Logistic regressions with adjustments for complex survey design used child welfare agency ties to substance abuse treatment providers and schools to predict treatment. As expected, adolescents were more likely to report treatment when child protective services and substance abuse treatment were in the same agency and when child welfare agency directors reported joint planning with schools. However, child welfare agency agreements with substance abuse treatment providers were negatively associated with treatment. This unexpected finding implies that agencies may sometimes cooperate to address problems as well as to improve service utilization. PMID:20870374

    We examined correlations of child sexual abuse among 300 adolescent girls in psychiatric inpatient treatment. Diagnostic and Statistical Manual of Mental Disorders (4th ed.)-based psychiatric diagnoses were obtained from the Schedule for Affective Disorder and Schizophrenia for School-Age Children-Present and Lifetime and from data on family and behavioral characteristics from the European Addiction Severity Index (EuropASI). A total of 79 girls (26.3%) had experienced child sexual abuse during their lifetime. Child sexual abuse was associated with an adolescent's home environment, sibling status, smoking, posttraumatic stress disorder diagnosis, self-mutilating behavior, and suicidal behavior. At least 62% of the perpetrators were acquaintances of the victims. Correlates of child sexual abuse can be used to identify child sexual abuse victims and persons at heightened risk for child sexual abuse.

    Full Text Available Background This study deals with the link between forced migration and sexual abuse, with a special focus on adolescent girls. Existing literature associates forced migration with sexual abuse and identifies adolescent girls as the most vulnerable. However, little is known about the situation of sexual abuse among Congolese refugees in Rwanda since their arrival in 2012 due to the conflict between Congolese government forces and the M23 rebel group. This study was initiated to explore the situation of sexual abuse of Congolese adolescent girls in Kigeme camp and to suggest remedial strategies. Participants and procedure Qualitative data were collected through individual interviews and focus group discussions (FGDs with adolescent girls. Interviews also involved parents, boys, camp authorities, and neighbouring citizens. Results The findings show that rape, unwanted physical touching, sexual exploitation, commercial sex, early marriage and girl trafficking are the main forms of sexual abuse. These are facilitated by the miserable life in the camp, shortcomings in the camp layout and security system, and adolescent developmental stage. They negatively impact girls’ reproductive health, social integration and mental health. Conclusions Existing strategies to address sexual abuse in the camp have had positive but insufficient results, and thus need to be improved and reinforced. Improvement is suggested in the areas of the abuse reporting system, the camp layout and security system, involvement of men and youth, and the consolidation of anti-GBV (gender-based violence clubs.

    Holliday, Erica; Gould, Thomas J

    2016-06-01

    In order to continue the decline of smoking prevalence, it is imperative to identify factors that contribute to the development of nicotine and tobacco addiction, such as adolescent initiation of nicotine use, adolescent stress, and their interaction. This review highlights the biological differences between adolescent and adults in nicotine use and resulting effects, and examines the enduring consequences of adolescent nicotine administration. A review of both clinical and preclinical literature indicates that adolescent, but not adult, nicotine administration leads to increased susceptibility for development of long-lasting impairments in learning and affect. Finally, the role stress plays in normal adolescent development, the deleterious effects stress has on learning and memory, and the negative consequences resulting from the interaction of stress and nicotine during adolescence is reviewed. The review concludes with ways in which future policies could benefit by addressing adolescent stress as a means of reducing adolescent nicotine abuse. Copyright © 2016 Elsevier Ltd.

    Adolescents naturally experience an increased interest in sexual behavior, but they usually lack much experience. Thus, any prescription medication that holds the potential to ease or facilitate sexual matters holds a unique allure. Widespread cultural awareness of medications to treat erectile dysfunction (ED) has combined with a recent trend toward increased adolescent prescription drug abuse to create unique challenges for industry, clinicians, and researchers.

    2009-07-01

    The presence of sexual abuse among societies in Botswana is a phenomenon whose occurrence is usually denied albeit the police report on it and legal frameworks have been established to combat it. Several factors influence the concealment of sexual abuse among adolescent girls, which includes cultural factors and social status of the perpetrators. This paper espouses the concept of sexual abuse among adolescent girls, the existence of the problem, its magnitude, the factors that increase vulnerability to violence and abuse, and how these factors intersect with HIV and AIDS. Two case studies using a discovery method were used to explore the phenomenon under the study. The findings of the study indicated that sexual abuse and violence have profound mental health consequences including guilt, anxiety, depression and anger. Future research is suggested to explore this problem on a wider scale and develop interventions that can assist victims and perpetrators to cope with the situation.

  1. Amygdala habituation to emotional faces in adolescents with internalizing disorders, adolescents with childhood sexual abuse related PTSD and healthy adolescents

    Full Text Available Adolescents with internalizing disorders and adolescents with childhood sexual abuse related post-traumatic stress disorder (CSA-related PTSD show a large overlap in symptomatology. In addition, brain research indicated hyper-responsiveness and sustained activation instead of habituation of amygdala activation to emotional faces in both groups. Little is known, however, about whether the same patterns of amygdala habituation are present in these two groups. The current study examined habituation patterns of amygdala activity to emotional faces (fearful, happy and neutral in adolescents with a DSM-IV depressive and/or anxiety disorder (N = 25, adolescents with CSA-related PTSD (N = 19 and healthy controls (N = 26. Behaviourally, the adolescents from the internalizing and CSA-related PTSD group reported more anxiety to fearful and neutral faces than adolescents from the control group and adolescents from the CSA-related PTSD group reacted slower compared to the internalizing group. At the whole brain level, there was a significant interaction between time and group within the left amygdala. Follow-up ROI analysis showed elevated initial activity in the amygdala and rapid habituation in the CSA-related PTSD group compared to the internalizing group. These findings suggest that habituation patterns of amygdala activation provide additional information on problems with emotional face processing. Furthermore, the results suggest there are differences in the underlying neurobiological mechanisms related to emotional face processing for adolescents with internalizing disorders and adolescents with CSA-related PTSD. Possibly CSA-related PTSD is characterized by a stronger primary emotional response driven by the amygdala.

    2014-01-01

    Research on child sexual abuse has focused on adult revictimization and outcomes. This article examines the rate of child maltreatment revictimization among male and female children reported to child protective services for child sexual abuse and whether revictimization impacts outcomes. Using longitudinal administrative data, Cox regressions were used to examine relationships between initial report of child sexual abuse, maltreatment revictimization, and adolescent outcomes among children from poor and nonpoor families. Despite no significant differences in child sexual abuse rates between poor and nonpoor families, poor child sexual abuse victims were significantly more likely to have re-reports for maltreatment. Children with multiple reports were more likely to have negative outcomes. Interventions for child sexual abuse survivors should focus on preventing maltreatment recurrence generally and not ignore needs of male victims.

    Full Text Available Abstract Background Association between psychiatric morbidity and substance abuse among adolescent has been reported. However prevalence and pattern of such dysfunctions are unknown in our environment. Aims To determine the prevalence of psychosocial dysfunction and depressive symptoms among adolescents who abuse substance and also note the influence of socio-demographic factors and type of substance on the pattern of dysfuction. Method A cross-sectional study was carried out among 900 adolescents selected from 29 secondary schools in Enugu metropolis. A multi-stage sampling procedure was used to select the students. The student drug use questionnaire was used to screen respondents for substance abuse. Those who were abusing substance and matched controls (non substance abusers were assessed for psychiatric symptoms using the 35-item Paediatric Symptom Checklist (PSC and the Zung Self-rating Depression Scale (SDS. Social classification was done using the parental educational attainment and occupation. Result A total of 290 students were current substance abusers. The substances most commonly abused were alcohol (31.6%, cola nitida (kola nut (20.7% and coffee (15.7%. Using the PSC scale, 70 (24.1% subjects compared to 29 (10.7% of the controls had scores in the morbidity range of ≥ 28 for psychosocial dysfuction. This was statistically significant (χ2 = 17.57 p = 0.001. Fifty-four subjects (18.6% had scores in the morbidity range of ≥ 50 for depressive symptoms using the Zung SDS compared to 21 (7.7% of controls. This was statistically significant (χ2 = 14.43, p = 0.001. Prevalence of dysfunction was not significantly related to age in both subjects and controls (χ2 = 4.62, p = 0.010, χ2 = 4.8, p = 0.10 respectively. Also using both scales, there was no significant relationship between psychosocial dysfunction and gender or social class in both subjects and control. The prevalence of dysfuction using both scales was significantly higher

    In Colombia, one out of five women between the ages of 15 and 19 years have been pregnant. Almost two-thirds (64%) of these pregnancies were unplanned. To examine the socio-demographic, psychosocial and clinical risk factors associated with adolescent pregnancy. An analytical prevalence study was performed using secondary data from the First Demographic Study of Mental Health in Medellin, Colombia. Female adolescents between 13 and 19 years of age were included in the study. The population was evaluated using the Composite International Diagnosis Interview, a structured interview developed by the World Health Organization, which establishes diagnoses according to the DSM-IV and ICD-10 criteria. A sample of 499 female adolescents was obtained, in which 135 adolescent pregnancies were identified, representing a prevalence of 21.5%. The large majority (84.4%) were between 16 and 19 years old. The median age was 17 years, with an interquartile range of 2 years. Almost two-thirds (61.2%) of female adolescents had initiated sexual activity at the age of 15 or later. Almost one-third (31.9%) reported being physically abused during childhood, and 6.7% sexually abused. Of those who were pregnant, 66.7% reported previous sexual abuse. A bivariate analysis showed that sexual abuse (OR=7.68), childhood negligence (OR=4.33), and having a partner (OR=6.31) were factors associated with an adolescent pregnancy. Negligence and sexual abuse in childhood and adolescence can be prevented, and adolescent pregnancies can be decreased. This finding has important implications for clinical management and prognosis, and requires public preventive policies. Copyright © 2016 Asociación Colombiana de Psiquiatría.

    This article explores the rates of co-occurring disorders in two large federally-funded programs that target youth. In the mental health treatment system, the Substance Abuse and Mental Health Services Administration's (SAMHSA) Center for Mental Health Services (CMHS) supports the Comprehensive Community Mental Health Services for Children and Their Families Program. SAMHSA's Center for Substance Abuse Treatment (CSAT) supports a number of grant programs providing substance abuse treatment for adolescents. The data from these programs underscores the need for the use of systematic, validated, biopsychosocial assessment instruments for all youth entering either the substance abuse or mental health treatment systems. The current evidence base for models of co-occurring treatment for youth is discussed and recommendations made for future activity related to adolescent co-occurring treatment.

  7. Proposal for a new detection method of substance abuse risk in Croatian adolescents

    2011-01-01

    Full Text Available One of the most important factors of successful substance abuse treatment is the early start of the same treatment. Recent selection method for identification of Croatian adolescents in the substance abuse risk that has been using drug tests from urine samples, has been simple and exact on the one hand, but on the other, has been very rare and usually guided by the pressure of parents or the court. Besides, such method presented the source of legal and ethical questions. So, the proposal of application of standardized psychological tests during systematic medical exams of Croatian adolescents at the age range of 15-22 years could help with the early detection of those adolescents who were in the substance abuse risk or already had the developed addiction problem.

    Identify and analyze cases of child and adolescent abuse and neglect in Curitiba, Brazil. This is an exploratory descriptive study that takes a quantitative approach. Secondary data from the reporting registry of the Network for the Protection of Children and Adolescents at Risk for Violence in Curitiba, Brazil, dating from 2004 to 2009, were analyzed. Variables included the victims' sociodemographic profile, place of notification, type, nature and severity of abuse, information about the author of the aggression or abuse, and physical lesions. The frequency distribution and associations between the variables were analyzed using the Chi-square test at a 5% significance level. The analysis of 19,316 records showed that domestic violence, abuse and neglect directed against children and adolescents were the most frequently recorded situation, with 17,082 cases (88.4%) distributed in the following manner: neglect, with 9742 reports (57.0%); physical violence, with 1341 reports (7.9%); sexual violence, with 796 reports (4.7%); psychological violence, with 574 reports (3.4%); and abandonment, with 190 reports (1.1%). Of the total, 43.9% were considered severe cases. The most affected age group was between 5 and 14 years of age, with balance between genders. In the majority of cases, the mother was registered as the author of the abuse or neglect. Physical sequelae (20.2%) mostly affected the head and upper and lower limbs, with consequent lesions manifesting as bruises, cuts, and fractures. An increase in the visibility of domestic violence and children and adolescents abuse and neglect has been observed in the city during the last few years, suggesting the effectiveness of the reporting strategies proposed by the protection network. It is important to increase social security and public welfare policies to prevent child and adolescent abuse and neglect, focusing on family support.

    Social factors influence drug abuse. Conversely, drugs of abuse alter social behavior. This is especially pertinent during post-weaning development, when there are profound changes in the social repertoire, and the sensitivity to the positive and negative effects of drugs of abuse is altered. This study aimed to provide an overview of our current understanding of the interaction between drugs of abuse and juvenile/adolescent social behavior. We first provide evidence that a characteristic form of juvenile and adolescent social behavior, i.e., social play behavior, has reinforcing properties and is affected by drugs of abuse. Next, social risk factors for drug use and addiction are described, including antisocial personality traits and early social insults. Last, we discuss research that investigates social influences on drug use, as well as the consequences of perinatal drug exposure on later social interactions. Social play behavior is highly rewarding in laboratory animals, and it is affected by low doses of opioids, cannabinoids, ethanol, nicotine, and psychostimulants. In humans, antisocial personality traits, most prominently in the form of conduct disorder, are a prominent risk factor for drug addiction. Preclinical studies have consistently shown altered sensitivity to drugs as a result of social isolation during post-weaning development. The social environment of an individual has a profound, but complex, influence on drug use, and perinatal drug exposure markedly alters later social interactions. The studies reviewed here provide a framework to understand the interaction between drugs of abuse and adolescent social interaction, at the preclinical and the clinical level.

    Prospective longitudinal data from 585 families were used to examine parents' reports of child physical abuse in the first 5 years of life as a predictor of substance use at ages 12, 16, and 24. Path analyses revealed that physical abuse in the first 5 years of life predicted subsequent substance use for females but not males. We found a direct effect of early physical abuse on girls'substance use at age 12 and indirect effects on substance use at age 16 and age 24 through substance use at age 12. For boys, age 12 substance use predicted age 16 substance use, and age 16 substance use predicted age 24 substance use, but physical abuse in the first 5 years of life was unrelated to subsequent substance use. These findings suggest that for females, a mechanism of influence of early physical abuse on substance use into early adulthood appears to be through precocious initiation of substance use in early adolescence.

    Children's affective experiences and cognitive abilities have an impact on emotion understanding. However, their relative contribution, as well as the possibility of an interaction between them, has rarely been examined. The aim of the present study was to evaluate the influence of severe abuse and learning difficulties on simple and complex components of emotion understanding in late childhood and early adolescence. A total of 28 older children and young adolescents were selected for the study. Half of the participants had suffered from severe abuse, and half of these abused children additionally had learning disabilities. The remaining half of the sample had no history of abuse but were matched with the abused children on learning difficulties, age and gender. The participants' emotion understanding was assessed with the Test of Emotion Comprehension (TEC). Results showed that (a) learning difficulties but not abuse had an impact on emotion understanding, (b) there was no interaction effect of abuse and learning difficulties on emotion understanding, and (b) the observed effects of learning difficulties were most apparent for the understanding of relatively complex components of emotion and not for simple components. The results are discussed in terms of their theoretical and practical implications.

    Much is known about the prevalence and correlates of dating violence, especially the perpetration of physical dating violence, among older adolescents. However, relatively little is known about the prevalence and correlates of the perpetration of cyber dating abuse, particularly among early adolescents. In this study, using a predominantly ethnic-minority sample of sixth graders who reported ever having had a boyfriend/girlfriend (n = 424, 44.2 % female), almost 15 % reported perpetrating cyber dating abuse at least once during their lifetime. Furthermore, using a cross-sectional design, across multiple levels of the socio-ecological model, the individual-level factors of (a) norms for violence for boys against girls, (b) having a current boyfriend/girlfriend, and (c) participation in bullying perpetration were correlates of the perpetration of cyber dating abuse. Collectively, the findings suggest that dating violence interventions targeting these particular correlates in early adolescents are warranted. Future studies are needed to establish causation and to further investigate the relative importance of correlates of the perpetration of cyber dating abuse among early adolescents that have been reported among older adolescents.

    This study tested the hypothesis that adolescent-onset alcohol abuse (AOAA) would both mediate and moderate the effect of childhood conduct disorder on antisocial behaviour in late adolescence and early adulthood. A sample comprising 504 young men and women strategically recruited from the community were grouped using the criteria of the Diagnostic and Statistical Manual (DSM-IV, American Psychiatric Association. (1994). Diagnostic and statistical manual of mental disorders (4th ed.). Washington, DC: APA), as follows: neither childhood conduct disorder (CCD) nor alcohol abuse/dependence; CCD but no alcohol abuse or dependence; alcohol abuse/dependence but no CCD; both CCD and alcohol abuse/dependence. The outcome measure was the sum of positive responses to 55 interview items capturing a variety of antisocial behaviours engaged in since age 15. Severity of lifetime alcohol-related and CCD problems served as predictor variables in regression analysis. Antisocial behaviour problems were greatest in individuals with a history of co-occurring conduct disorder (CD) and alcohol abuse/dependence. While CCD was strongly predictive of adult antisocial behaviour, this effect was both mediated and moderated (exacerbated) by AOAA.

    This study tested the hypothesis that basic social information-processing components represented by family conflict, peer aggression, and pro-aggression cognitive scripts are related to aggression and social problems among adolescents in substance abuse treatment. The sample consisted of 547 adolescents in two community-based residential facilities. Correlation results indicated that more peer aggression is related to more pro-aggression scripts; scripts, peer aggression, and family conflict ...

  20. Emergence of Sex Differences in the Development of Substance Use and Abuse during Adolescence

    Substance use and abuse begins during adolescence. Male and female adolescent humans initiate use at comparable rates, but males increase use faster. In adulthood, more men than women use and abuse addictive drugs. However, some women progress more rapidly from initiation of use to entry into treatment. In animal models, adolescent males and females consume addictive drugs similarly. However, reproductively mature females acquire self-administration faster, and in some models, escalate use more. Sex/gender differences exist in neurobiologic factors mediating both reinforcement (dopamine, opioids) and aversiveness (CRF, dynorphin), as well as intrinsic factors (personality, psychiatric co-morbidities) and extrinsic factors (history of abuse, environment especially peers and family) which influence the progression from initial use to abuse., Many of these important differences emerge during adolescence, and are moderated by sexual differentiation of the brain. Estradiol effects which enhance both dopaminergic and CRF-mediated processes contribute to the female vulnerability to substance use and abuse. Testosterone enhances impulsivity and sensation seeking in both males and females. Several protective factors in females also influence initiation and progression of substance use including hormonal changes of pregnancy as well as greater capacity for self-regulation and lower peak levels of impulsivity/sensation seeking. Same sex peers represent a risk factor more for males than females during adolescence, while romantic partners increase risk for women during this developmental epoch. In summary, biologic factors, psychiatric co-morbidities as well as personality and environment present sex/gender-specific risks as adolescents begin to initiate substance use. PMID:26049025

    2010-07-01

    "Prevention of Adolescent Reoccurring Violence and Alcohol Abuse: A Multiple Site Evaluation" is a multiple component alcohol abuse and violent behavior prevention strategy, targeted to adolescents ages 16-21 who have high levels of anger, or who are victims/perpetrators of violence, and their families. Three community centers located in upstate New York provided group participants (N = 210) known to have conduct disorder and substance abuse history. The centers were used as the intervention sites over a seven-week period with the youth assessment staff using objective screening measures. The participants were exposed to a two-pronged intervention, using a parental involvement cohort with approximately half of the study participants. The Teams, Games, and Tournaments strategy was the intervention method. Teams, Games, and Tournaments is a Social Learning Theory-based intervention with demonstrated empirical evidence of the model's effectiveness. A 2 x 3 factorial design with two follow-up points encompassed: anger control, alcohol/substance abuse, and family interactive education. The goals of the study were to help adolescents reduce their alcohol use, to increase productive family interaction, and ultimately to reduce the adolescents' aggression levels and subsequently reduce the possibility of their becoming victims or perpetrators of a violent crime. Consistent with Social Learning Theory, the Teams, Games, and Tournaments treatment intervention makes use of adolescents as peer counselors. The practical implications include that professionals or students in our public schools, juvenile courts, correctional institutions, and residential treatment centers can easily implement this program. A standardized treatment manual is available. It offers a complete, ready-to-use, and cost-effective tool for reducing adolescent violence and alcohol abuse. Further, the data provide support for a hypothesis of social learning theory, that is: interventions using multiple

    This article presents the initial psychometric properties of a treatment planning and progress inventory for adolescents with sexual behavior problems, the Treatment Progress Inventory for Adolescents Who Sexually Abuse (TPI-ASA). The TPI-ASA was designed to monitor common elements of specialized treatment for youth with sexual behavior problems. The TPI-ASA measures nine dimensions relevant to the evaluation and treatment of adolescents with sexual behavior problems (inappropriate sexual behavior, healthy sexuality, social competency, cognitions supportive of sexual abuse, attitudes supportive of sexual abuse, victim awareness, affective/behavioral regulation, risk prevention awareness, and positive family caregiver dynamics). Members of the Association for the Treatment of Sexual Abusers completed the TPI-ASA with 90 male adolescents with sexual behavior problems as part of a psychosexual evaluation. The preliminary findings provided support for the internal consistency and convergent and discriminant validity of the dimensions. Suggestions are offered for additional research on the TPI-ASA and its potential as a clinical tool.

    The aim was to understand variables contributing to the occurrence of sexual offending in children and adolescents. Twenty youngsters who had engaged in coercive sexual behavior involving other children were compared to a matched group of clinic-referred youngsters with conduct disorders. Assessments included family histories, interviews, and psychometric measures. There was no group difference in the frequency of experiencing sexual abuse. However, sexually abusive youngsters were more often exposed to adult caregivers with known histories of being sexually abusive. These children had been subjected to multiple distortions of adult attachment, tended to internalize distress, and failed to use available social supports. They were likely to have experienced physical and verbal abuse; children with behavior disorders were more likely to have a parent with a psychiatric illness and to have experienced parental conflict. Severely disrupted attachment, in conjunction with family experiences of inappropriate sexual expression, place children and adolescents at risk for sexual offending. Sexually abusive youngsters had less social supports and their offending occurred after a negative emotional experience, when there was opportunity in the form of younger victims. The study suggests an interaction among developmental pathways, coping skills, and immediate proximal variables for the perpetration of sexual abuse by young people.

    1995-01-01

    This multiple case study of ten families of normal private preparatory school adolescents and five families of substance abusing/mood disordered adolescents was an effort to identify factors that may suggest a relationship between the abuse of substances in adolescents who also have mood disorders and the following family factors: parental marital discord, degree of family satisfaction, and family problem-solving styles. The fifteen families completed four assessment instruments and participated in a videotaped problem-solving exercise. The results of this study showed that all members of the substance abusing/mood disordered adolescents' families rated themselves as dysfunctional in all major areas of family life. In contrast, the normal private preparatory school families reported satisfaction with most areas of family functioning. Communication styles also differed considerably between the two small groups of families. These results appear to support the importance of family evaluation and treatment when addressing the issue of adolescent substance abusers with mood disorders.

  20. Relativistic Runaway Electrons

    Breizman, Boris

    2014-10-01

    This talk covers recent developments in the theory of runaway electrons in a tokamak with an emphasis on highly relativistic electrons produced via the avalanche mechanism. The rapidly growing population of runaway electrons can quickly replace a large part of the initial current carried by the bulk plasma electrons. The magnetic energy associated with this current is typically much greater than the particle kinetic energy. The current of a highly relativistic runaway beam is insensitive to the particle energy, which separates the description of the runaway current evolution from the description of the runaway energy spectrum. A strongly anisotropic distribution of fast electrons is generally prone to high-frequency kinetic instabilities that may cause beneficial enhancement of runaway energy losses. The relevant instabilities are in the frequency range of whistler waves and electron plasma waves. The instability thresholds reported in earlier work have been revised considerably to reflect strong dependence of collisional damping on the wave frequency and the role of plasma non-uniformity, including radial trapping of the excited waves in the plasma. The talk also includes a discussion of enhanced scattering of the runaways as well as the combined effect of enhanced scattering and synchrotron radiation. A noteworthy feature of the avalanche-produced runaway current is a self-sustained regime of marginal criticality: the inductive electric field has to be close to its critical value (representing avalanche threshold) at every location where the runaway current density is finite, and the current density should vanish at any point where the electric field drops below its critical value. This nonlinear Ohm's law enables complete description of the evolving current profile.

    Kelley, Michelle L; Fals-Stewart, William

    2008-01-01

    The focus of this study was whether couples-based treatment for substance abuse had comparable secondary benefits on the internalizing and externalizing behaviors of adolescent versus child siblings living in their homes. Couples took part in a couples-based treatment for substance abuse that combines Behavioral Couples Therapy and individual counseling (i.e., Learning Sobriety Together). During a 17-month assessment period, the relationship between parents' functioning (i.e., fathers' drug use as determined by percent days abstinent and parents' dyadic adjustment) as rated by mothers, fathers, and children's teachers and internalizing behavior (as rated by mothers' only) was stronger for children than their adolescent siblings, particularly in terms of children's externalizing behaviors. Interventions that reduce paternal drug use and improve couple functioning may reduce internalizing and externalizing symptoms for children in their homes; however, adolescents may need more intensive interventions to address internalizing and externalizing symptoms.

    This study estimated prevalence of HIV risk behaviors and its association with substance use and mental health problems among adolescents in treatment. A pooled dataset of 9,519 adolescents admitted to substance abuse treatment programs between 2002 and 2006 was analyzed. HIV risk behaviors, substance use, and mental health problems were assessed at treatment intake. Sixty percent of adolescents were engaged in at least one sexual or needle use risk behavior in the year prior to entering treatment. Sex with multiple partners, sex under the influence of alcohol or drugs, and unprotected sex were the most prevalent HIV risk behaviors. Several gender differences were found for specific types of sexual and needle use behaviors. Adolescents with substance dependence or other comorbid mental health problems were at increased odds for HIV risk. Findings suggest treatment programs may benefit adolescents better by screening them consistently for HIV risk behaviors and incorporating tailored interventions.

Controls were established for abuse-related variables (type of abuse, severity and multiple abuse in a representative sample of high schools students in the province of Quebec. A total of 15.2% of adolescent females and 4.4% adolescent males in high school reported a history of sexual abuse in childhood. Sexually abused adolescent females (27.8% were more likely than adolescent males (14.9% to achieve scores with high clinical levels of PTSD. Hierarchical logistic regression revealed that over and above the characteristics of the sexual abuse experienced, resilience factors (maternal and peer support contributed to the prediction of symptoms of PTSD attaining the clinical threshold. Alternative intervention and prevention practices geared to adolescent victims of sexual assault are discussed.

    Abused children and adolescents are exposed to factors that can trigger vocal changes. This study aimed to analyze the prevalence of vocal changes in abused children and adolescents, through auditory-perceptual analysis of voice and the study of the association between vocal changes, communication disorders, psychiatric disorders, and global functioning. This was an observational and transversal study of 136 children and adolescents (mean age 10.2 years, 78 male) who were assessed by a multidisciplinary team specializing in abused populations. Speech evaluation was performed (involving the aspects of oral and written communication, as well as auditory-perceptual analysis of voice, through the GRBASI scale). Psychiatric diagnosis was performed in accordance with the DSM-IV diagnostic criteria and by applying the K-SADS; global functioning was evaluated by means of the C-GAS scale. The prevalence of vocal change was 67.6%; of the patients with vocal changes, 92.3% had other communication disorders. Voice changes were associated with a loss of seven points in global functioning, and there was no association between vocal changes and psychiatric diagnosis. The prevalence of vocal change was greater than that observed in the general population, with significant associations with communication disorders and global functioning. The results demonstrate that the situations these children experience can intensify the triggering of abusive vocal behaviors and consequently, of vocal changes.

    Objective. The aim of the study was to determine the relation between inhalant abuse and conduct disorders in adolescents. Material and methods. Authors studied 95 adolescents with ICD-10 diagnoses conduct disorders (F91.1, 91.2), "Mental and behavioral disorders due to use of inhalant abuse. Harmful use" (F18.1) and "Inhalant drug dependence" (F18.2). "The Nisonger Child Behavior Rating Form" ("NCBRF, TIQ version") and "Adolescent Drug Abuse Diagnosis (ADAD)" ("EvroADAD" version) were used. Two teenager groups were investigated: the younger (mean age 14.35±0.844 years) one and the older (mean age 16.30±0.464 years) ones. Clinical manifestations of inhalant intoxication and symptoms of addiction were described. Using cluster analysis, the relation of clinical manifestations of conduct disorder with symptoms of inhalant addiction and its consequences were calculated. Results and conclusion. In the younger group, no significant statistical relationships were found. In the older group, 3 cluster were detected: 1) the variables that characterized the relationship of inhalant abuse with typical behavioral patterns such as delinquency, school and social maladjustment; 2) the variables that characterized the transformation of the inhalant use to alcohol use which was associated with hyperkinetic conduct disorder; 3) the variables that characterize a pronounced health and psychological consequences of the inhalant use.

    To explore significant experiences of adolescents as next of kin that the general practitioner (GP) should identify and recognize. Qualitative study with focus-group interviews. Three focus-group interviews were conducted with a total of 15 Norwegian adolescents each with an ill or substance-abusing parent. The participants were recruited from existing support groups. The adolescents' days were dominated by unpredictability in their family situation and their own exhausting efforts to keep up an ordinary youth life. Mostly, they consulted GPs for somatic complaints. In encounters with the GP, they wanted to be met both as a unique person and as a member of a family with burdens. Their expectations from the GP were partly negatively formed by their experiences. Some had experienced that both their own and their parent's health problems were not addressed properly. Others reported that the GP did not act when he or she should have been concerned about their adverse life situation. The GP may contribute to better long-term psychosocial outcomes by ensuring that the adolescents receive information about the parent's illness and have someone to talk to about their feelings and experiences. In addition, the GP may help by supporting their participation in relieving activities. Burdened adolescents seek a GP most often for somatic complaints. The GP has a potential to support them by taking the initiative to talk about their life situation, and by recognizing their special efforts. Key points Little is known about how a general practitioner can support adolescents with ill or substance-abusing parents. Adolescents experience unpredictability in life and strive to find balance between their own needs and the restrictions caused by parental illness. In encounters with adolescents having ill parents, the GP should take the initiative to talk about their family situation. The GP may help them by recognizing their experiences and struggles, give information, offer talks and

    Full Text Available Childhood sexual abuse is often associated with a number of deleterious psychological and behavioural outcomes for survivors. However, some research suggests that this impact is variable and that some survivors adapt positively. An ability to adapt positively to adversity, under any circumstances, has been termed resilience. Drawing on a socio-ecological understanding of resilience, the aim of this scoping review was to comprehensively map existing empirical studies on resilience processes in sexually abused adolescent girls and to summarise emerging resilience-enabling factors. We also considered the implications of the findings for practice and research. A total of 11 articles met the criteria for inclusion in the review. Findings from these studies suggest that internal factors (meaning making, optimistic future orientation, agency and mastery and contextual factors (supportive family, social and educational environments function interdependently to enable resilience in sexually abused adolescent girls. Practitioners should leverage these complementary and interdependent resilience-enabling mechanisms by encouraging greater involvement of girls in the planning of interventions and by assisting girls in developing meaningful narratives about their abuse experiences. Interventions should also encourage greater involvement from supportive structures, while challenging social and cultural norms that inhibit resilience. Resilience researchers should be cognisant of the paucity of research focusing on resilience processes in sexually abused adolescent girls as well as the absence of innovative, participatory methods of data collection. Significance: The review adds to a body of literature on resilience processes with implications for resilience researchers. The findings have implications for a range of practitioners (psychologists, social workers, teachers etc. who work with sexually abused girls.

  11. Stress in adolescence and drugs of abuse in rodent models: Role of dopamine, CRF, and HPA axis

    2014-01-01

    Rationale Research on adolescence and drug abuse increased substantially in the past decade. However, drug-addiction related behaviors following stressful experiences during adolescence are less studied. We focus on rodent models of adolescent stress cross-sensitization to drugs of abuse. Objectives Review the ontogeny of behavior, dopamine, corticotropin-releasing factor (CRF), and the hypothalamic pituitary adrenal (HPA) axis in adolescent rodents. We evaluate evidence that stressful experiences during adolescence engender hypersensitivity to drugs of abuse and offer potential neural mechanisms. Results and Conclusions Much evidence suggests that final maturation of behavior, dopamine systems, and HPA axis occurs during adolescence. Stress during adolescence increases amphetamine- and ethanol-stimulated locomotion, preference, and self-administration under many conditions. The influence of adolescent stress on subsequent cocaine- and nicotine-stimulated locomotion and preference is less clear. The type of adolescent stress, temporal interval between stress and testing, species, sex, and the drug tested are key methodological determinants for successful cross-sensitization procedures. The sensitization of the mesolimbic dopamine system is proposed to underlie stress cross-sensitization to drugs of abuse in both adolescents and adults through modulation by CRF. Reduced levels of mesocortical dopamine appear to be a unique consequence of social stress during adolescence. Adolescent stress may reduce the final maturation of cortical dopamine through D2 dopamine receptor regulation of dopamine synthesis or glucocorticoid-facilitated pruning of cortical dopamine fibers. Certain rodent models of adolescent adversity are useful for determining neural mechanisms underlying the cross-sensitization to drugs of abuse. PMID:24370534

    This study aimed to describe the family context characteristics of high school adolescents and their relation to psychoactive substance abuse. It is a cross-sectional and descriptive study, with a population of 657 secondary-school students in the city of Leon, Nicaragua, which corresponded to 31% of the research context. Data was collected through an anonymous questionnaire. Results show that 56% of the adolescents were living with both parents and 32% only with the mother, 86% declared a good relationship with the mother, but 24% did not show confidence in the mother figure. Regarding psychoactive substance use within the family context, 52% of the adolescents' family presented previous use events and, in 42% of cases, the father was the user. Results offer important contributions to design public healthcare policies and to outline prevention strategies for use among adolescents.

    Studies conducted outside of Scandinavia indicate that most adolescents with substance misuse problems suffer from co-morbid mental disorders. The present study assessed the mental health of adolescents seeking help for substance misuse problems in a large Swedish city. Parents' mental health was also examined. The sample included 97 girls with their 90 mothers and 52 fathers, and 81 boys with their 72 mothers and 37 fathers. The adolescents completed a diagnostic interview, either the Kiddie-SADs or the Structured Clinical Interview for DSM-IV (SCID) depending on their age. Their parents underwent diagnostic interviews with the SCID. Ninety per cent of the girls and 81% of the boys met criteria for at least one disorder other than substance misuse, and on average, they suffered from three other disorders, most of which had onset before substance misuse began. Almost 80% of the mothers and 67% of the fathers met criteria for at least one mental disorder other than alcohol and drug-related disorders. The findings concur with those reported from studies conducted in North America. The results suggest that in Sweden mental disorders are not being identified and effectively treated among some children and young adolescents who subsequently abuse alcohol and/or illicit drugs. Adolescents who consult for substance abuse problems require assessments and treatment by mental health professionals.

  1. Antisocial Psychopathy and HIV Risk among Alcohol and Other Drug (AOD Abusing Adolescent Offenders

    Full Text Available While the consensus is that HIV prevalence has remained low among adolescent offenders, the prevalence of STDs and HIV transmission risk behaviors is alarming, particularly for those abusing alcohol and other drugs and those displaying antisocial or conduct disorder characteristics. In the current study, 269 male and 110 female inner city, culturally diverse alcohol and other drug (AOD abusing adolescent offenders completed measures of (a psychopathy, using the Millon Adolescent Clinical Inventory (MACI (b HIV transmission risk behavior, (c prevention skills and attitudes and (d social desirability. Results showed that those with high levels of psychopathy reported more AOD use, overall unprotected sex and more sexual activity when influenced by alcohol and/or marijuana. High psychopathy adolescent offenders also reported lower self-efficacy and sexual response-efficacy, less favorable safer sex and condom attitudes and less favorable intentions to engage in safer sex behaviors, when controlling for social desirability. Data suggest that adolescent offenders, who are either in court-ordered treatment or detention, should be assessed for psychopathy and provided with tailored risk reduction interventions, geared toward attitudinal and behavioral change. A discussion of integrating neurobiological measures to improve the next generation of tailored interventions for this risk group is offered in conclusion.

    Full Text Available Childhood abuse has been associated with significant increases in non-suicidal self-injury (NSSI behaviors in adolescents; however, only general definitions of this risk indicator have been examined. This study identified relationships between specific forms of childhood abuse and NSSI in mainland Chinese adolescents.A total of 14,221 cases were retained from an epidemiological study involving adolescents from junior and senior middle schools. Information relating to the perpetrator, perceived harm, timing of exposure to different types of childhood abuse, and NSSI were obtained. Logistic regression was used to analyze relationships between each form of childhood abuse and NSSI.Approximately 51.0% of the students reported at least one abusive childhood experience. Nearly one in four students (24.9% reported that they had engaged in NSSI in the past 12 months. Each type of childhood abuse, occurring at any time within the first 16 years of life, especially in situations of continuous exposure, was significantly associated with NSSI. A significant graded relationship was found between number of abusive childhood experiences and NSSI. Students maltreated by parents or others were at high risk of engaging in NSSI, the risk was greater in students maltreated by both; students who had been exposed to childhood abuse with no perceived harm still demonstrated an elevated risk for NSSI. The pattern of associations did not vary by gender.These findings suggest that experiencing any of various forms of childhood abuse should be considered a risk factor for NSSI during adolescence. Further research should focus upon psychosocial, neural, and genetic factors that might moderate or mediate the onset of NSSI in adolescents who have experienced childhood abuse.

    The sexual assault of girls and women in this country is estimated at approximately 20%. The development of post-traumatic stress disorder (PTSD) after sexual abuse and assault is one of the potential lingering aftereffects. In this article we describe PTSD after sexual abuse and its effect on presenting complaints, such as sexually transmitted infections, contraception, and chronic pain, for the pediatric and adolescent gynecology (PAG) clinician. Treatment approaches, including the use of antidepressants and anxiolytics, as well as evidenced-based psychotherapies, are highlighted. In addition, this article will assist the PAG clinician in identifying trauma-related concerns during clinic visits and will cover specific screening tools to aid in identification of PTSD. A better understanding of PTSD after sexual abuse will allow PAG providers to deliver better care to their patients.

    Parental substance abuse confronts children with a variety of psychological, social, and behavioral problems. Children of substance abusing parents show higher levels of psychiatric disorders including anxiety and depression and exert lower levels of communication skills. Weak social skills in this group of adolescents put them at a higher risk for substance abuse. Many studies showed school based interventions such as life skill training can effective on future substance abusing in these high risk adolescences. The participants consisted of 57 middles schools girls, all living in rural areas and having both parents with substance dependency. The participants were randomly assigned to intervention (n=28) and control (n=29) groups. The data were collected before and six weeks after training in both group. The intervention group received eight sessions of group assertiveness training. Participants were compared in terms of changes in scores on the Oxford Happiness Questionnaire and the Gambrills-Richey Assertion Inventory. The total score for happiness change from 43.68 ±17.62 to 51.57 ±16.35 and assertiveness score changed from 110.33±16.05 to 90.40±12.84. There was a significant difference in pretest-posttest change in scores for intervention (7.89±4.13) and control (-2.51±2.64) groups; t (55) =2.15, p = 0.049. These results suggest that intervention really does have an effect on happiness and assertiveness. Determining the effectiveness of these school based interventions on other life aspects such as substance abuse calls for further study on these rural adolescent girls.

  5. Runaway electrons and ITER

    2016-10-01

    ITER planning for avoiding runaway damage depends on magnetic surface breakup in fast relaxations. These arise in thermal quenches and in the spreading of impurities from massive gas injection or shattered pellets. Surface breakup would prevent a runaway to relativistic energies were it not for non-intercepting flux tubes, which contain magnetic field lines that do not intercept the walls. Such tubes persist near the magnetic axis and in the cores of islands but must dissipate before any confining surfaces re-form. Otherwise, a highly dangerous situation arises. Electrons that were trapped and accelerated in these flux tubes can fill a large volume of stochastic field lines and serve as a seed for the transfer of the full plasma current to runaways. If the outer confining surfaces are punctured, as by a drift into the wall, then the full runaway inventory will be lost in a short pulse along a narrow flux tube. Although not part of ITER planning, currents induced in the walls by the fast magnetic relaxation could be used to passively prevent outer surfaces re-forming. If magnetic surface breakup can be avoided during impurity injection, the plasma current could be terminated in tens of milliseconds by plasma cooling with no danger of runaway.

    To examine the effects of incorporating tribal specific cultural beliefs into a tailored substance abuse prevention intervention for at risk rural Oklahoma Native American Indian (NAI) Plains adolescents. The 10 hour Native American Talking Circle Intervention, a school-based, group substance abuse prevention program, was implemented over a 8.5 week period and evaluated using a one group, pretest-posttest design. Measurements were from the Native Self-Reliance Questionnaire and the Substance Problems Scale from Global Appraisal of Individual Needs-Quick (GAIN-Q). One-tailed, paired sample t-tests demonstrated significant increase in self-reliance, from 86.227 to 92.204 (t (43) = -2.580, p = .007) and a decrease in substance abuse/use, from 2.265 to 1.265 (t (33) = 1.844, p = .007). The Native Talking Circle Intervention based on tribal-specific values and beliefs was shown to be effective with substance abuse/use at-risk NAI Plains tribal adolescents.

    During the past twenty years, various instruments have been developed for the assessment of substance use in adolescents, mainly in the United States. However, few of them have been adapted to, and validated in, French-speaking populations. Consequently, although increasing alcohol and drug use among teenagers has become a major concern, the various health and social programs developed in response to this specific problem have received little attention with regard to follow-up and outcome assessment. A standardized multidimensional assessment instrument adapted for adolescents is needed to assess the individual needs of adolescents and assign them to the most appropriate treatment setting, to provide a single measurement within and across health and social systems, and to conduct treatment outcome evaluations. Moreover, having an available instrument makes it possible to develop longitudinal and transcultural research studies. For this reason, a French version of the Adolescent Drug Abuse Diagnosis (ADAD) was developed and validated at the University Child and Adolescent Psychiatric Clinic in Lausanne, Switzerland. This article aims to discuss the methodological issues that we faced when using the ADAD instrument in a 4-year longitudinal study including adolescent substance users. Methodological aspects relating to the content and format of the instrument, the assessment administration and the statistical analyses are discussed.

    Maltreatment is associated with chronic depression, high negative self-attributions, and lifetime psychopathology. Adolescence is a sensitive period for the formation of self-concept. Identifying neurobiomarkers of self-processing in depressed adolescents with and without maltreatment may parse the effects of trauma and depression on self-development and chronic psychopathology. Depressed adolescents (n = 86) maltreated due to omission (DO, n = 13) or commission (DCM, n = 28) or without maltreatment (DC, n = 45), and HCs (HC, n = 37) appraised positive and negative self-descriptors in the scanner. DCM and DO showed hypoactivity in the dorsal anterior cingulate cortex (dACC) while processing positive versus negative self-descriptors compared to DC youth, who in turn showed reduced dACC recruitment versus HC. HC youth showed the highest activation in the dACC and striatum during positive self-descriptors; these regions showed a linear decline in activity across DC, DO, and DCM. Low dACC activity to positive versus negative self-descriptors was linked to inadequate coregulation of children's emotions by parents. Negative self-cognitions prevalent in DCM and DO adolescents may be perpetuated by activity in the dACC and striatum. Reduced activation of the dACC and striatum for positive self-descriptors, coupled with enhanced activity for negative self-descriptors, may heighten the risk for persistent depression.

    The present study aimed to assess the factor structure of the childhood trauma questionnaire (CTQ; Bernstein & Fink, 1998), and use it to describe the prevalence of abuse and neglect in Indian adolescents, and its associations with gender, family structure (nuclear vs. joint), and level of parental education. Participants were 702 adolescents from Jammu in the age range of 13-17 years (41.5% female). We found acceptance for a four-factor intercorrelated model for the CTQ with emotional abuse, physical abuse, sexual abuse, and neglect (5 emotional neglect and 2 physical neglect items) factors following a confirmatory factor analysis (CFA). Forty-one to sixty-one percent of adolescents reported maltreatment which is higher in comparison with CTQ based studies from the West. Analysis of CFA with covariates (MIMIC model) indicated that males, and adolescents of less educated mothers' and from joint families reported higher abuse and neglect, and sexual abuse, respectively, while fathers' education level was not associated with abuse or neglect. Implications of these findings are highlighted.

    Recently there has been an alarming increase in the number of schoolchildren sniffing glue (toluene). The medical complications seen in 18 boys, aged 14 to 18 years, include physical and mental dependence, pulmonary hypertension with cor pulmonale, restrictive lung defect, encephalopathy, peripheral neuropathy and high frequency, continuous discharges ( neuromyotonia ) on electromyogram. Glue sniffing took place in small groups and abusers sniffed directly from cans containing glue. Lower socio-economic status, overcrowding, lack of attention by working parents, school failure and easy availability of the glue were commonly cited associated factors.

    Although a number of management strategies are available for adolescent substance abusers, the outcomes are limited due to high drop out. The factors related to drop out in adolescent substance users, especially in low and middle income countries (LAMIC) have been sparsely studied. To study the personal, family and clinical variables related to immediate drop out in adolescent substance abusers. A retrospective outpatient chart review was carried out for adolescent substance abusers aged 12-19 years from January 2012 to December 2014. Of the 89 patients, 57 (64%) dropped out immediately. The majority of adolescent substance users were >17 years (85%), having some education (90%), belonging to a joint family (76%), having good family support (66%). Drop out was higher in those with later onset and less duration of substance abuse (3.42 vs. 2.36, p=0.014), not currently employed/attending school (OR=2.65, 95% CI=1.04-6.70), not having a psychiatric comorbidity, using a single substance and abusing cannabis. Factors like school drop out, background, family type and support and the relationship to the accompanying person were not associated with immediate drop out. Later onset, lesser duration of substance use, not currently employed/attending school, absence of psychiatric illness and using cannabis were associated with drop out from outpatient treatment. These factors must be thoroughly addressed in substance abuse interventions.

    Full Text Available OBJECTIVE(S: To investigate associations between alcohol drinking by parents at different time of their life and alcohol use by adolescents.DESIGN: The longitudinal epidemiological study design was used to answer the proposed research questions. This study is based on the data of the Family and Children of Ukraine Study (FCOU, which is a prospective cohort study of women and children. PARTICIPANTS: Recruited subjects were pregnant women with last menstrual period (LMP between 25 December 1992 and 23 July 1994. Self-completed questionnaires and the medical record data were collected at the first antenatal clinic visit and at the delivery. The sample in the city of Dniprodzerzhynsk consists of 2148 women, their children and partners (if any, but at 15-17-years-old follow-up only data about 1020 participants were available. MAIN EXPOSURES: Use of alcohol by mother/father before pregnancy, during pregnancy, and at 15-17 years of child’s age.OUTCOME MEASURE: Use of alcohol by 15-17-year-old adolescent.RESULTS: Use of alcohol more than once a week by mother before pregnancy was associated with alcohol abuse by adolescents, unlike father’s use of alcohol before and during pregnancy. Use of alcohol both by mother and father during adolescence of their offspring was strongly associated with alcohol abuse by the child. In the multivariate analysis only alcohol use by mother during adolescence of the child was significantly associated with alcohol use by the adolescent.CONCLUSIONS: This study supports the hypothesis that concurrent social factors influence regular alcohol use among adolescents more intensively than early life factors.

    Full Text Available Globally 320 million young people between ages 15-29 years are dying from alcohol related causes. Child line foundation survey report showed that 13.1% of the people involved in drug and substance abuse in India, are adolescents. India’s 1.2 billion populations contain the largest number of street children of the world who are at risk of substance abuse. But there is a gap in reliable data of adolescent substance abuse patterns in Assam as well as in India. Substance abuse pattern in the slums need more research. It was a community based cross sectional study. Study period was three months, from 15th July to 15th October 2012. Six slums of Guwahati city were selected purposively. Both male and female adolescents between the ages of 10-19 years with past or present history of any substance abuse, permanent residents of these slums, with guardian and self-consents given to take part in this study were included in the study. Each study subject was interviewed by personal interview method using a predesigned pretested Performa. Total 60 respondents, 20 from each of the selected slums were interviewed in detail. Male: Female ratio was 4:1, 93.3% were current abusers, maximum (46.7% in the age group of 14-16 years. 58% were students and living with families (93% though 30% of the respondents had single parenting. 25% of the respondents were illiterate and 93.3% were from lower socioeconomic status. 78.3% had history of drug abuse in their families and more than 2/3rd got information about the different substances from their peers and friends.

    Negative consequences of alcohol abuse during adolescence have been extensively described. Consequently, different interventions have been developed to address this issue. This article describes the implementation and evaluation of Iudicium, an educational drama-based intervention designed to increase risk perception of alcohol abuse. In this activity, high school students judge a case in which alcohol consumption had negative consequences (e.g., fights, unwanted pregnancy, and car accident). A trial is simulated and after that, a debriefing takes place during which the activity is discussed and informational materials on the effects of alcohol is provided and commented. A total of 318 students (55.7% females and 44.3% males) from five high schools participated in the study. Data regarding risk perception of alcohol abuse and adequacy of the activity was collected before and after the intervention. Results suggest that Iudicium was effective in increasing risk perception of abusive drinking, reaching a 34% of increase regarding risk perception. Participants highlighted the experiential component of Iudicium as a strength. The intervention was well-accepted, easy to understand and apparently an effective tool for increasing risk perception of alcohol abuse amongst high school students.

  20. Inter-personal violence and abuse in adolescent intimate relationships: mental health impact and implications for practice.

    Barter, Christine; Stanley, Nicky

    2016-10-01

    This paper provides a narrative review of the knowledge on inter-personal violence and abuse (IPVA) in adolescents' intimate relationships. It draws on the authors' own research, published reviews, and a rapid review on IPVA victimization and mental health outcomes for adolescents. The research reviewed identified associations between adolescent IPVA and substance misuse, depressive symptoms and PTSD, eating disorders and suicidal thinking, and behaviour in young people. Generally, girls appeared more likely to report severe mental health outcomes than boys. Adolescents rarely disclose IPVA to adults and delivering preventative programmes that promote knowledge and help seeking may offer a means of building on young people's tendency to seek help from friends. These preventative interventions, usually delivered in schools, need to be closely linked to support services for adolescents who disclose abuse. While there are some practice examples of emerging interventions for both victims and perpetrators of adolescent IPVA, there is as yet little robust evidence regarding their effectiveness.

  1. An animal model of social instability stress in adolescence and risk for drugs of abuse.

    McCormick, Cheryl M

    2010-02-09

    There is increasing evidence that adolescence, like early life, is a sensitive period in which ongoing brain development can be influenced by environmental factors. This review describes our use of social instability as a model of mild adolescent social stress, its effects on social interactions and on hypothalamic-pituitary-adrenal function over the course of the procedure and in response to new stressors. The effects of social instability are sex-specific, with qualitative differences between the sexes on HPA function over the course of the stressor procedure, and with greater effects in males on behaviour observed during the social instability and greater effects in females on behavioural responses to drugs of abuse into adulthood, long after the stress exposure. The results from investigations with this model of adolescent social stress are discussed in relation to those of studies using other stressor procedures. Elevated exposure to glucocorticoids over the course of adolescence confers sex-specific changes in behavioural responses to drugs of abuse, which may be of relevance for understanding risk factors in people.

    Research on adult intimate partner violence has demonstrated that economic considerations and financial decision-making are associated with the use of violence in marital and cohabiting relationships. Yet limited work has examined whether financial behaviors influence the use of violence in adolescent dating relationships. We use data from the National Survey on Teen Relationships and Intimate Violence (STRiV) (n = 728), a comprehensive national household survey dedicated specifically to the topic of adolescent relationship abuse, to examine associations between requests for money lending, economic control/influence, financial socialization and adolescent relationship abuse among a large, diverse sample of male and female adolescents [48 % female; 30 % non-White, including Black (10 %), Hispanic (2 %), and other (18 %)]. Findings suggest that requests for money lending are associated with heightened risk of moderate and serious threats/physical violence perpetration and victimization, net of traditional predictors. We discuss the implications of our findings for intervention and prevention efforts.

    Drug testing is often used as part of an assessment for substance use in children and adolescents. However, the indications for drug testing and guidance on how to use this procedure effectively are not clear. The complexity and invasiveness of the procedure and limitations to the information derived from drug testing all affect its utility. The objective of this clinical report is to provide guidance to pediatricians and other clinicians on the efficacy and efficient use of drug testing on the basis of a review of the nascent scientific literature, policy guidelines, and published clinical recommendations.

    Full Text Available Abstract Background Use of alcohol and illicit drugs by adolescents remains a problem in the U.S. Case identification and early treatment can occur within a broad variety of healthcare and non-healthcare settings, including acute care hospitals. The objective of this study is to describe the extent and nature of adolescent admissions to the acute inpatient setting for substance abuse (SA. We use the Agency for Healthcare Research and Quality (AHRQ 2000 Healthcare Cost and Utilization Project Kids Inpatient Database (HCUP-KID which includes over 2.5 million admissions for youth age 20 and under to 2,784 hospitals in 27 states in the year 2000. Specifically, this analysis estimates national number of admissions, mean total charges, and mean lengths of stay for adolescents between the ages of 12 and 17 admitted to an acute care hospital for the following diagnostic categories from the AHRQ's Clinical Classifications Software categories: "alcohol-related mental disorders" and "substance-related mental disorders". Frequency and percentage of total admissions were calculated for demographic variables of age, gender and income and for hospital characteristic variables of urban/rural designation and children's hospital designation. Results SA admissions represented 1.25 percent of adolescent admissions to acute care hospitals. Nearly 90 percent of the admission occurred in non-Children's hospitals. Most were for drug dependence (38% or non-dependent use of alcohol or drugs (35%. Costs were highest for drug dependence admissions. Nearly half of admissions had comorbid mental health diagnoses. Higher rates of admission were seen in boys, in older adolescents, and in "self-pay" patients. Alcohol and drug rehabilitation/detoxification, alone or in combination with psychological and psychiatric evaluation and therapy, was documented for 38 percent of admissions. Over 50 percent of cases had no documentation of treatment specific to substance use behavior

    Although the literature suggests that childhood maltreatment (CM) relates to adolescent heavy episodic drinking (HED), few studies have examined the long-term effects of CM on adolescent HED. This study is the first to examine associations between exposure to CM and trajectories of HED from adolescence to young adulthood for the US population. Four waves of data from the National Longitudinal Study of Adolescent Health were used. A total of 8503 adolescents followed from adolescence (7th-12th grades) into young adulthood (ages 24-32) were assessed on CM and past-year HED frequency. Using growth curve modeling, trajectories of adolescent HED were examined, with subtype, frequency, and severity of CM as the primary independent variables. All of our analyses controlled for common risk factors for adolescent HED, including demographics, parental and peer alcohol use, parental education and employment, family income, parent-child relationship, and adolescent depression. After controlling for potential risk factors, neglect and physical abuse, both individually and in conjunction, were associated with faster increases in HED during adolescence and persistently elevated HED over much of adolescence and young adulthood. The frequency of neglect and physical abuse, individually and in conjunction, was also associated with the trajectory of HED, such that additional instances of these types of maltreatment were associated with faster increases in HED during adolescence and higher rates of peak use during young adulthood. Child neglect and physical abuse appear to have long-lasting adverse effects on HED beyond adolescence and throughout much of young adulthood. Copyright © 2012 Elsevier Ireland Ltd.

    Among the negative sequelae of child maltreatment is increased risk for continuity of maltreatment into subsequent generations. Despite acknowledgment in the literature that the pathways toward breaking the cycle of maltreatment are likely the result of dynamic interactions of risk and protective factors across multiple ecological levels, few studies have followed high-risk samples of maltreated and nonmaltreated parents over time to evaluate such processes. In the current investigation, exposure to community violence and authoritarian parenting attitudes were evaluated as predictors of the intergenerational continuity of abuse, and the moderating effect of African American race was examined. The sample included 70 mothers and their 18-year-old children, who have been followed longitudinally since the third trimester of the adolescent mothers' pregnancy. Results revealed that among mothers with a child abuse history, higher exposure to community violence and lower authoritarian parenting attitudes were associated with increased risk for intergenerational continuity of abuse. The relation of authoritarian parenting attitudes to intergenerational continuity was moderated by race; the protective effects of authoritarian parenting were limited to the African American families only. The salience of multiple ecological levels in interrupting the intergenerational continuity of child abuse is discussed, and implications for preventive programs are highlighted.

    Besides other explanatory variables, parenting styles and parental violence might also be responsible for setting a path towards overweight/obesity in childhood. While this association has consistently been observed for adults, findings for adolescents still remain scarce and inconsistent. Therefore, the goal of this study is to add evidence on this topic for children and adolescents. Analyses are based on a sample of 1729 German, ninth-grade students. To analyze associations between parenting dimensions and weight status, non-parametric conditional inference trees were applied. Three gender-specific pathways for a heightened risk of overweight/obesity were observed: (1) female adolescents who report having experienced severe parental physical abuse and medium/high parental warmth in childhood; (2) male adolescents who report having experienced low or medium parental monitoring in childhood; and (3) this second pathway for male adolescents is more pronounced if the families receive welfare. The importance of promoting parenting styles characterized by warmth and a lack of physical abuse is also discussed. This is one of only a few studies examining the association of parenting dimensions/parental physical abuse and weight status in adolescence. Future studies should include even more parenting dimensions, as well as parental physical abuse levels, in order to detect and untangle gender-specific effects on weight status.

    Individuals with histories of childhood trauma may adopt a nonspecific memory retrieval strategy to avoid unpleasant and intrusive memories. In a sample of 93 adolescents and adults with or without histories of child sexual abuse (CSA), we tested the hypothesis that nonspecific memory retrieval is related to an individual's general tendency to use avoidant (i.e., distancing) coping as a personal problem-solving or coping strategy, especially in victims of CSA. We also examined age differences and other individual differences (e.g., trauma-related psychopathology) as predictors of nonspecific memories. Distancing coping was significantly associated with less specific autobiographical memory. Younger age, lower vocabulary scores, and non-CSA childhood maltreatment (i.e., physical and emotional abuse) also uniquely predicted less autobiographical memory specificity, whereas trauma-related psychopathology was associated with more specific memory. Implications for the development of autobiographical memory retrieval in the context of coping with childhood maltreatment are discussed.

    The association of sexual victimization with self-esteem, depression, and problematic internet use was examined in Korean adolescents. A total of 695 middle and high school students were recruited (413 boys, 282 girls, mean age, 14.06±1.37 years). The participants were administered the Early Trauma Inventory Self Report-Short Form (ETISR-SF), Rosenberg's Self-Esteem Scale (RSES), the Children's Depression Inventory (CDI), and Young's Internet Addiction Test (IAT). The associations between sexual abuse and the level of self-esteem, depressive symptoms, and problematic internet use were analyzed. Adolescents who had experienced sexual abuse showed lower self-esteem, more depressive symptoms, and greater problematic internet use compared with adolescents who had not experienced sexual abuse. In the path model, sexual abuse predicted lower self-esteem (β=-0.11; 95% CI=-0.20, -0.04; p=0.009), which predicted higher depressive symptoms (β=-0.34; 95% CI=-0.40, -0.27; p=0.008). Depressive symptoms predicted problematic internet use in a positive way (β=0.23; 95% CI=0.16-0.29; p=0.013). Sexual abuse also predicted problematic internet use directly (β=0.20; 95% CI=0.12-0.27; p=0.012). The results of the present study indicate that sexually abused adolescents had a higher risk of depression and problematic internet use. For sexually abused adolescents, programs aimed at raising self-esteem and preventing internet addiction, as well as mental health screening, are needed.

    2013-01-01

    Childhood sexual abuse (CSA) is thought to be a precursor to substance use and sexual risk behaviors during adolescence. To inform adolescent prevention efforts, information is needed to explicate the nature of the relationships between CSA and these health risks. The aim of this study was to summarize the current literature on the associations between a history of CSA and substance use and sexual risk behaviors during adolescence. We conducted a systematic literature search and an integrative review. Current evidence implicates CSA as a robust precursor to the use of a wide variety of substances and multiple sexual risk behaviors during adolescence. Screening for CSA in adolescents at risk and incorporating strategies that enhance CSA recovery in adolescent prevention programs are warranted. Future research that includes longitudinal designs, uses multiple methods of assessment, and identifies pathways between CSA and adolescent health risks is recommended. Copyright © 2013 Elsevier Inc.

  17. Prevention of adolescent substance abuse through the development of personal and social competence.

    The initiation of substance use typically begins during adolescence and appears to be the result of the complex interplay of social, personality, cognitive, attitudinal, behavioral, and developmental factors. Traditional smoking, alcohol, and drug education programs have attempted to increase students' knowledge of the risks associated with using these substances in the hope that this would deter use. Other programs have attempted to enrich the personal and social development of students through what has been referred to as "affective" education. Unfortunately, the inescapable conclusion to be drawn from the substance abuse prevention literature is that few of these programs have demonstrated any degree of success in terms of the actual prevention of substance use/abuse. Traditional educational approaches to substance abuse prevention appear to be inadequate because they are based on faulty assumptions and are too narrow in their focus. The "affective" education approaches, on the other hand, appear to have placed too little emphasis on the acquisition of the kind of skills that are likely to increase general personal competence and enable students to cope with the various interpersonal and intrapersonal pressures to begin using tobacco, alcohol, or drugs. From the perspective of social learning theory (Bandura 1977) and problem behavior theory (Jessor and Jessor 1977), substance use is conceptualized as a socially learned, purposive, and functional behavior which is the result of the interplay of social (environmental) and personal factors. One potentially effective approach to substance abuse prevention might involve enhancing general personal competence and teaching adolescents the kind of problem-specific skills and knowledge which will increase their ability to resist the various forms of pro-substance-use social pressure. Brief reviews of the social skills training literature and the literature related to techniques for coping with anxiety not only provide

    The Ministries of Justice and Education have implemented adolescent substance abuse prevention programs for many years. Rates of substance abuse among high school students continue to rise in spite of such programs. This study investigates adolescents' substance abuse-related knowledge and attitudes and self-confidence to resist substance use in order to identify predictive factors of poor adolescent resistance to substance use. A cross-sectional study survey gathered data on substance abuse-related knowledge and attitudes and self-confidence to resist substance use from 243 second-year senior high school students studying at two schools in northern Taiwan. Participants were most knowledgeable about tobacco (80.2%), followed by alcohol (72.0%), ecstasy (56.0%), and marijuana (30.0%). Only 19.3% demonstrated an understanding of the harmful effects of using Ketamine. A 10-point Likert scale measured participant substance use attitudes. Alcohol was the substance participants were most willing to use (2.18 ± 3.27), followed by tobacco (0.66 ± 2.19), ecstasy (0.45 ± 1.88), Ketamine (0.43 ± 1.93), and marijuana (0.38 ± 1.83). Participants had higher awareness of the harmful effects of Ketamine (t = -2.37, p = .018), marijuana (t = -2.33, p = .021), and tobacco (t = -2.02, p = .044), with participants reporting greater self-confidence to resist using these three substances. Multiple regression analysis found the three most important factors affecting participant self-confidence to resist substance use to be gender (β= .26, p knowledge about the substance (β= .15, p = .028), and attitude toward substance use (β= -.20, p Level of harmful effects knowledge and attitudes toward use varied among the various substances considered in this paper. Being female, having strong knowledge about the substance, and negative attitude toward substance use correlated with higher levels of self-confidence to resist substance use. Study results will be used in ongoing research

    We argue that moduli stabilization generically restricts the evolution following transitions between weakly coupled de Sitter vacua and can induce a strong selection bias towards inflationary cosmologies. The energy density of domain walls between vacua typically destabilizes Kahler moduli and triggers a runaway towards large volume. This decompactification phase can collapse the new de Sitter region unless a minimum amount of inflation occurs after the transition. A stable vacuum transition ...

  1. Runaway electrons and ITER

    The potential for damage, the magnitude of the extrapolation, and the importance of the atypical—incidents that occur once in a thousand shots—make theory and simulation essential for ensuring that relativistic runaway electrons will not prevent ITER from achieving its mission. Most of the theoretical literature on electron runaway assumes magnetic surfaces exist. ITER planning for the avoidance of halo and runaway currents is focused on massive-gas or shattered-pellet injection of impurities. In simulations of experiments, such injections lead to a rapid large-scale magnetic-surface breakup. Surface breakup, which is a magnetic reconnection, can occur on a quasi-ideal Alfvénic time scale when the resistance is sufficiently small. Nevertheless, the removal of the bulk of the poloidal flux, as in halo-current mitigation, is on a resistive time scale. The acceleration of electrons to relativistic energies requires the confinement of some tubes of magnetic flux within the plasma and a resistive time scale. The interpretation of experiments on existing tokamaks and their extrapolation to ITER should carefully distinguish confined versus unconfined magnetic field lines and quasi-ideal versus resistive evolution. The separation of quasi-ideal from resistive evolution is extremely challenging numerically, but is greatly simplified by constraints of Maxwell’s equations, and in particular those associated with magnetic helicity. The physics of electron runaway along confined magnetic field lines is clarified by relations among the poloidal flux change required for an e-fold in the number of electrons, the energy distribution of the relativistic electrons, and the number of relativistic electron strikes that can be expected in a single disruption event.

    It is estimated that the percentage of students using illicit substances by sixth grade has tripled over the last decade not only in developed countries but in developing countries as well probably due to the transition to a more Western society. Although much has been done to understand the mechanisms underlying substance abuse, few studies have been conducted with minority ethnic and religious groups such as Middle Eastern Youth. The primary goal of this study was to determine whether there are differences in factors contributing to substance abuse in adolescents from Lebanon versus the U.S.A. and to decipher the role of spirituality, religion, and culture among other factors that may influence substance abuse. A correlational cross-sectional design was used with adolescents living in two different countries: Los Angeles, California and Beirut, Lebanon. Muslim adolescents had significantly less rates of alcohol and substance use than Christians in both Lebanon and Los Angeles. More years lived in the U.S.A. increases the likelihood of abuse for both Muslims and Christians. Attachment to God and family was negatively associated with substance abuse. These results among others facilitate a better understanding of the influence of culture, religion, family and personal factors on substance abuse. Culturally sensitive interventions could benefit from the findings of this pilot study.

    Commitment to change is an innovative potential mediator or mechanism of behavior change that has not been examined in adolescents with substance use disorders (SUD). The Adolescent Substance Abuse Goal Commitment (ASAGC) questionnaire is a 16-item measure developed to assess an individual's commitment to his/her stated treatment goal. The objectives of this study are to explore the research and clinical utility of the commitment construct as measured by the ASAGC. During sessions 3 and 9 of a 10-week SUD treatment, therapists completed the ASAGC for 170 13-18 year-old adolescents. An exploratory factor analysis was conducted on the ATAGC items. Concurrent validity with related constructs, self-efficacy and motivation for change, was examined as well. At both sessions, the factor analysis resulted in two scales--Commitment to Recovery and Commitment to Harm Reduction. The ASAGC scales were found to demonstrate a high level of internal consistency (alpha coefficients ranged from .92 to .96 over time). In contrast to the Commitment to Harm Reduction scale, the Commitment to Recovery scale consistently correlated with scales from the Situational Confidence Questionnaire assessing self-efficacy, evidencing concurrent validity. Similarly, the Commitment to Recovery scale was related to the Problem Recognition Questionnaire, providing further evidence of the validity of the ASAGC. The ASAGC is a reliable and valid clinical research instrument for the assessment of adolescents' commitment to their substance abuse treatment goal. Clinical researchers may take advantage of the clinical utility of the ASAGC including its ability to differentiate between commitment to abstinence versus commitment to harm reduction.

    Full Text Available OBJECTIVE: to analyze the factors associated with the underreporting on the part of nurses within Primary Health Care of abuse against children and adolescents.METHOD: cross-sectional study with 616 nurses. A questionnaire addressed socio-demographic data, profession, instrumentation and knowledge on the topic, identification and reporting of abuse cases. Bivariate and multivariate logistic regression was used.RESULTS: female nurses, aged between 21 and 32 years old, not married, with five or more years since graduation, with graduate studies, and working for five or more years in PHC predominated. The final regression model showed that factors such as working for five or more years, having a reporting form within the PHC unit, and believing that reporting within Primary Health Care is an advantage, facilitate reporting.CONCLUSION: the study's results may, in addition to sensitizing nurses, support management professionals in establishing strategies intended to produce compliance with reporting as a legal device that ensures the rights of children and adolescents.

    This randomized clinical trial examined longitudinal outcomes from an alcohol abuse prevention program aimed at urban youths. Study participants were an ethnically and racially heterogeneous sample of early adolescents, recruited from community-based agencies in greater New York City and its environs. Once they assented to study participation and gained parental permission, youths were divided into three arms: youth intervention delivered by CD-ROM (CD), the same youth intervention plus parent intervention (CD(P)), and control. Once all youths completed baseline measures, those in CD and CD(P) arms received a computerized 10-session alcohol abuse prevention program. Parents of youths in the CD(P) arm received supplemental materials to support and strengthen their children's learning. All youths completed postintervention and annual follow-up measures, and CD- and CD(P)-arm participants received annual booster intervention sessions. Seven years following postintervention testing and relative to control-arm youths, youths in CD and CD(P) arms reported less alcohol use, cigarette use, binge drinking, and peer pressure to drink; fewer drinking friends; greater refusal of alcohol use opportunities; and lower intentions to drink. No differences were observed between CD and CD(P) arms. Study findings lend support to the potential of computerized, skills-based prevention programs to help urban youth reduce their risks for underage drinking.

    Full Text Available O presente estudo propõe uma revisão bibliográfica sobre habilidades sociais e abuso de substâncias. Este artigo foi elaborado a partir de pesquisa nas Bases de Dados Pschynfo, Web of Science, Cochrane Library, Proquest, Medline e Lilacs, entre 1996 e 2006. Os descritores foram: social skills, social skills training, social competence, assertiveness, adolescents, teeenagers, substance abuse, drug abuse, cannabis e marijuana. Nas bases de língua portuguesa, foram: habilidades sociais, treinamento em habilidades sociais, assertividade, adolescentes, abuso de substâncias, drogas e maconha. Os estudos, a maioria de língua inglesa, apontaram a existência de déficits, principalmente a dificuldade em resistir às drogas e dizer não. Conclui-se que a construção de habilidades de resistência ao oferecimento de drogas, a auto-eficácia e o estímulo à capacidade de tomada de decisões pode reduzir o uso de substâncias. Poucos estudos brasileiros foram encontrados abordando esta temática.The present article proposes a bibliographic revision on social skills and drug abuse. This article was elaborated from a research in the following Databases: Pschynfo, Web of Science, Cochrane Library, Proquest, Medline and Lilacs, between 1996 and 2006. The used describers were: social skills, social skills training, social competence, assertiveness, adolescents, teenagers, substance abuse, drug abuse, cannabis and marijuana. In the databases in Portuguese language we used the terms habilidades sociais, treinamento em habilidades sociais, assertividade, adolescentes, abuso de substâncias, drogas and maconha. The studies, the majority of which were in English, pointed the existence of deficits, mainly the difficulty in resisting to drugs and in saying no. It can be concluded that the construction of resistance skills to the offering of drugs, self-efficacy training and the stimulation of decision making capabilities can reduce substance use.

    No known studies have tested the effectiveness of child abuse prevention programmes for adolescents in low- or middle-income countries. 'Parenting for Lifelong Health' ( http://tiny.cc/whoPLH ) is a collaborative project to develop and rigorously test abuse-prevention parenting programmes for free use in low-resource contexts. Research aims of this first pre-post trial in South Africa were: i) to identify indicative effects of the programme on child abuse and related outcomes; ii) to investigate programme safety for testing in a future randomised trial, and iii) to identify potential adaptations. Two hundred thirty participants (adolescents and their primary caregivers) were recruited from schools, welfare services and community-sampling in rural, high-poverty South Africa (no exclusion criteria). All participated in a 12-week parenting programme, implemented by local NGO childcare workers to ensure real-world external validity. Standardised pre-post measures with adolescents and caregivers were used, and paired t-tests were conducted for primary outcomes: abuse (physical, emotional abuse and neglect), adolescent behaviour problems and parenting (positive and involved parenting, poor monitoring and inconsistent discipline), and secondary outcomes: mental health, social support and substance use. Participants reported high levels of socio-economic deprivation, e.g. 60 % of adolescents had either an HIV-positive caregiver or were orphaned by AIDS, and 50 % of caregivers experienced intimate partner violence. i) indicative effects: Primary outcomes comparing pre-test and post-test assessments showed reductions reported by adolescents and caregivers in child abuse (adolescent report 63.0 % pre-test to 29.5 % post-test, caregiver report 75.5 % pre-test to 36.5 % post-test, both p child abuse and improved caregiver and adolescent outcomes. It showed high acceptability and unexpected community-level diffusion. Findings indicate needs for adaptations, and

    New results from the generation of runaways and the loss of runaway electrons in an ergodized magnetic field are presented. For the generation process, a clear difference between a 'normal' and a clean, freshly boronized wall condition has been found. Under clean wall conditions, one observes at low densities not only the runaway electrons with energies up to 30 MeV and at discharges with even lower electron density one finds more runaway electrons but at an energy in the low-MeV regime. The runaway electrons are utilized as test particles for revealing the ergodized magnetic field line structure. For the measurements the m/n = 6/2 base mode configuration of the dynamic ergodic divertor (DED), has been applied. One observes a clear modification of the radial runaway profile with preferential losses in the ergodized zone. From the loss rate of the runaway electrons due to ergodization and from the redistribution of the runaways after the DED phase, the diffusion rate is estimated to be of the order of 0.1 m2 s-1.

    Adolescent mothers are at increased risk of mistreating their children. Intervening before they become pregnant would be an ideal primary prevention strategy. Our goal was to determine whether psychopathology, exposure to maltreatment, preparedness for child-bearing, substance use disorders (SUDs), IQ, race, and socioeconomic status were associated with the potential for child abuse in nonpregnant adolescent girls. The Child Abuse Potential Inventory (CAPI) was administered to 195 nonpregnant girls (aged 15 to 16 years; 54% African American) recruited from the community. Psychiatric diagnoses from a structured interview were used to form 4 groups: conduct disorder (CD), internalizing disorders (INTs; that is, depressive disorder, anxiety disorder, or both), CD + INTs, or no disorder. Exposure to maltreatment was assessed with the Childhood Trauma Questionnaire, and the Childbearing Attitudes Questionnaire measured maternal readiness. CAPI scores were positively correlated with all types of psychopathology, previous exposure to maltreatment, and negative attitudes toward child-bearing. IQ, SUDs, and demographic factors were not associated. Factors associated with child abuse potential interacted in complex ways, but the abuse potential of CD girls was high, regardless of other potentially protective factors. Our study demonstrates that adolescent girls who have CD or INT are at higher risk of perpetrating physical child abuse when they have children. However, the core features of CD may put this group at a particularly high risk, even in the context of possible protective factors. Treatment providers should consider pre-pregnant counselling about healthy mothering behaviours to girls with CD.

    Using Swedish nationwide registry data, the authors investigated genetic and environmental risk factors in the etiology of drug abuse by twin sibling modeling. The authors followed up with epidemiological analyses to identify shared environmental influences on drug abuse. Drug abuse was defined using public medical, legal, or pharmacy records. Twin and sibling pairs were obtained from the national twin and genealogical registers. Information about sibling pair residence within the same household, small residential area, or municipality was obtained from Statistics Sweden. The authors predicted concordance for drug abuse by years of co-residence until the older sibling turned 21 and risk for future drug abuse in adolescents living with parental figures as a function of family-level socioeconomic status and neighborhood social deprivation. The best twin sibling fit model predicted substantial heritability for drug abuse in males (55%) and females (73%), with environmental factors shared by siblings operating only in males and accounting for 23% of the variance in liability. For each year of living in the same household, the probability of sibling concordance for drug abuse increased 2%-5%. When not residing in the same household, concordance was predicted from residence in the same small residential area or municipality. Risk for drug abuse was predicted both by family socioeconomic status and neighborhood social deprivation. Controlling for family socioeconomic status, each year of living in a high social deprivation neighborhood increased the risk for drug abuse by 2%. Using objective registry data, the authors found that drug abuse is highly heritable. A substantial proportion of the shared environmental effect on drug abuse comes from community-wide rather than household-level influences. Genetic effects demonstrated in twin studies have led to molecular analyses to elucidate biological pathways. In a parallel manner, environmental effects can be followed up by

    Child maltreatment is strongly associated with adolescent psychopathology and substance abuse and dependence. However, developmental processes unfolding from childhood into adolescence that delineate this trajectory are not well understood. The current study used path analysis in a structural equation modeling framework to examine multiple mediator models, including ego control, ego resiliency, and internalizing and externalizing symptoms to investigate this developmental process. Participants were 415 children, assessed across 3 waves of data, (i.e., at ages 7 to 9, 10 to 12, and 13 to 15). The sample included maltreated (n = 259) and nonmaltreated (n = 156) children; groups were comparable in sociodemographic characteristics. Findings support an transactional-ecological model by revealing a developmental sequence in which severity of early childhood maltreatment potentiates less adaptive childhood personality functioning, followed by externalizing problems in preadolescence, and ultimately adolescent cannabis abuse and dependence symptoms. A developmental pathway from child maltreatment to adolescent cannabis abuse and dependence symptoms via personality and preadolescent internalizing problems was not supported. Understanding developmental pathways by which maltreatment experiences increase risk for substance abuse and dependence symptoms in youth has far-reaching implications for the treatment and prevention of substance use disorders.

    Utilizing the large, longitudinal Minnesota Twin Family Study (N = 2510; 96 % European American ancestry), we examined the influence of several person-environment transactions on adolescent substance abuse. We focused on the two childhood personality traits found to be most predictive of substance abuse in this sample-socialization (willingness to follow rules and endorse conventional values) and boldness (social engagement and assurance, stress resilience, thrill seeking)-and the environmental variables of antisocial and prosocial peers, academic engagement, parent-child relationship quality, and stressful life events. Path analysis revealed that low socialization had a selection effect for each environmental risk factor, that is, socialization at age 11 predicted environmental risk at age 14, after controlling for the stability of the environmental variables from ages 11 to 14. Antisocial peers and academic engagement at age 14 then mediated some of the risk of low socialization on substance abuse at age 17, but the majority of risk for substance abuse was accounted for by the stability of socialization from age 11 to 14. Boldness at age 11 also increased risk for substance abuse, but did so primarily via a direct effect. The findings help to parse the nature of person-environment transactions across multiple personality traits and contextual risk factors that contribute to adolescent substance abuse.

    The objectives of the study were to assess the prevalence of child sexual abuse (CSA) in a nation-wide representative sample of 14-17 year old Israeli adolescents, and to examine the associations between CSA, socio-demographic correlates and various measures of physical and mental health. The study population consisted of 906 mother-adolescent dyads, belonging to a community based, representative sample of Israeli 14-17 year olds, interviewed in 2004-5. Response rate was 68%. Subjects provided demographic data, and information about CSA, physical symptoms, body image, well-being and use of mental health services. DAWBA was used to obtain information regarding mental disorders and suicidality. SDQ was used to obtain data on bullying. Statistical analyses were conducted using an SPSS-17 complex sample analysis module and multivariate analyses were conducted to assess the associations between CSA and risk factors and social and health related correlates. Findings show that CSA was reported by 3.3% of adolescents. Higher risk of exposure to CSA was found among girls, among adolescents living in a one-parent household and among adolescents with a chronic disability. In multivariate models adjusting for gender, learning disabilities and depression, CSA was associated with suicidal attempts, stomach ache, dizziness, sleep problems, well being at home and bullying behaviors. No association was found with suicidal ideation or other physical symptoms. Our findings confirm that the associations between CSA and different outcomes vary depending on the socio-psychological context, and underline the importance of addressing the complexity of variables associated with CSA.

    2014-01-01

    Risk factors for traumatic reenactments of child sexual abuse experiences (perpetration, revictimization, and self-injury) were examined in a sample of 718 South African secondary school adolescents. Logistic regression analyses indicated that the most consistent predictors of reenactments were a history of child sexual abuse (rape and/or indecent assault) and respondents' gender, with males being significantly more likely than females to report perpetration (OR = 13.5) and females being more likely to report revictimization (OR = 3.2) and self-injury (OR = 2.5). An analysis restricted to respondents with a history of child sexual abuse indicated that negative abuse-related cognitions were the most consistent predictor of all forms of traumatic reenactment.

    The study investigated the relationship among physical abuse, positive psychological factors including emotional competence and social problem-solving, and suicidal ideation among adolescents in China. The possible moderating effects of emotional competence and social problem-solving in the association between physical abuse and adolescent suicidal ideation were also studied. A cross-sectional survey employing convenience sampling was conducted and self-administered questionnaires were collected from 527 adolescents with mean age of 14 years from the schools in Shanghai. Results showed that physical abuse was significantly and positively related to suicidal ideation in both male and female adolescents. Emotional competence was not found to be significantly associated with adolescent suicidal ideation, but rational problem-solving, a sub-scale of social problem-solving, was shown to be significantly and negatively associated with suicidal ideation for males, but not for females. However, emotional competence and rational problem-solving were shown to be a significant and a marginally significant moderator in the relationship between physical abuse and suicidal ideation in females respectively, but not in males. High rational problem-solving buffered the negative impact of physical abuse on suicidal ideation for females. Interestingly, females with higher empathy and who reported being physically abused by their parents have higher suicidal ideation. Findings are discussed and implications are stated. It is suggested to change the attitudes of parents on the concept of physical abuse, guide them on appropriate attitudes, knowledge and skills in parenting, and enhance adolescents' skills in rational problem-solving.

    To assess the influence of peer alcohol use during adolescence on young adults' alcohol use and abuse, and to assess to what extent parents' perception of their adolescent child's friends and adolescent's self-control modify this influence. We analyzed data from the first, third, and fourth wave of a population-based prospective cohort study of 2230 adolescents conducted between 2001 and 2010 (mean ages: 11.1, 16.3, and 19.1, respectively). Alcohol use and abuse were measured at T4 by self-report questionnaires and by the Composite International Diagnostics Interview (CIDI), respectively. Peer alcohol use, self-control, and parents' perception of their adolescent child's friends were measured at T3. We adjusted for gender, age, socioeconomic-status, parental alcohol use, and adolescent baseline alcohol use. Peer alcohol use during adolescence was related to young adults' alcohol use and abuse [odds ratio (95% confidence interval): 1.31 (1.11-1.54) and 1.50 (1.20-1.87), respectively]. Neither parents' perception of their adolescent child's friends nor self-control modified this relationship. Alcohol abusers were more likely to have low self-control than alcohol users. No differences were found between alcohol users and abusers regarding their parents' perception of their friends and peer alcohol use. Peer alcohol use during adolescence affects young adults' alcohol use and abuse. We found that self-control was only related to alcohol abuse. Peer influence was not modified by parents' perception of peers or by self-control. Peer alcohol use and self-control should thus be separate targets in the prevention of alcohol use/abuse. © 2013.

    This study evaluates the mediational role of general attributions in explaining the impact of specific attributions regarding sexual abuse (SA) on six posttraumatic symptoms. One hundred three SA female adolescents (13-17 years old) completed the Trauma Symptoms Checklist for Children (TSCC; Briere, 1989), the blame/guilt subscale of the Children's Impact of Traumatic Events Scale (CITES-R; Wolfe, Gentile, Michienzi, Sas, & Wolfe, 1991), and the Personal Attributions for Negative Events subscale of the Children's Attributions and Perceptions Scale (CAPS; Mannarino, Cohen, & Berman, 1994). Results indicate that general attributions act as a mediator between specific attributions and six posttraumatic symptoms (i.e., anxiety, depression, sexual concerns, posttraumatic stress, dissociation, and anger).

    2007-01-01

    In this study of 360 low-income mother-child dyads, our primary goal was to disentangle risks linked with commonly co-occurring maternal diagnoses: substance abuse and affective/anxiety disorders. Variable- and person-based analyses suggest that, at least through children's early adolescence, maternal drug use is no more inimical for them than is maternal depression. A second goal was to illuminate vulnerability and protective processes linked with mothers' everyday functioning, and results showed that negative parenting behaviors were linked with multiple adverse child outcomes. Conversely, the other parenting dimensions showed more domain specificity; parenting stress was linked with children's lifetime diagnoses, and limit setting and closeness with children's externalizing problems and everyday competence, respectively. Results are discussed in terms of implications for resilience theory, interventions, and social policy.

    2017-08-01

    Digital dating abuse (DDA) behaviors include the use of digital media to monitor, control, threaten, harass, pressure, or coerce a dating partner. In this study, 703 high school students reported on the frequency of DDA victimization, whether they were upset by these incidents, and how they responded. Results suggest that although both girls and boys experienced DDA at similar rates of frequency (with the exception of sexual coercion), girls reported that they were more upset by these behaviors. Girls also expressed more negative emotional responses to DDA victimization than boys. Although DDA is potentially harmful for all youth, gender matters. These findings suggest that the experience and consequences of DDA may be particularly detrimental for girls. Copyright © 2017 The Foundation for Professionals in Services for Adolescents.

    2005-03-01

    On two occasions separated by one year, Chinese adolescents with economic disadvantage in Hong Kong (N = 199) responded to instruments measuring perceived parental parenthood qualities (indexed by perceived parenting styles, support and help from parents, and conflict and relationship with the parents) and psychosocial adjustment (psychological well-being, substance abuse, and delinquency). Results showed that parental parenthood variables were concurrently associated with different measures of adolescent psychological well-being and problem behavior at Time 1 and Time 2. While paternal parenthood qualities at Time 1 predicted changes in existential well-being and delinquency in adolescent boys, but not in adolescent girls, at Time 2, maternal parenthood qualities at Time 1 predicted changes in the mental health and problem behavior in adolescent girls, but not in adolescent boys, at Time 2. There is no strong support for the thesis that adolescent adjustment influences perceived parental parenthood qualities over time. The present study suggests that the influences of fathers and mothers on the adjustment of Chinese adolescents experiencing economic disadvantage vary with the gender of adolescent children. 2004 Wiley Periodicals, Inc.

    Full Text Available The type of parental child-rearing practices used by parents and guardians substantially influence children’s self-esteem and consequently their decision to engage in alcohol use, its abuse. The aim of this study was to explore the role of self-esteem and parenting patterns on alcohol use and abuse among adolescents. Three hundred and sixteen boys and girls in Senior High Schools completed self-report questionnaires assessing self-esteem, parenting patterns and alcohol use and abuse. The results showed that while girls reported lesser self-esteem than boys, boys reported higher levels of alcohol use and abuse than girls. Also, authoritative parenting pattern had a positive effect on self-esteem and a negative effect on alcohol use. On the other hand, authoritarian and permissive parenting patterns had negative effects on self-esteem and positive effects on alcohol use, with slight variations. These results provide valuable information regarding strategies aimed at fostering parent-child relationship and rapport with the ultimate aim of bolstering the self-esteem of adolescents to subsequently eschew insalubrious behaviour, particularly alcohol use and abuse.

    Full Text Available BACKGROUND According to UNDCP World Drug Report, the problem of substance abuse in adolescence is fast assuming alarming proportions in both developed and developing nations. Kullu District of Himachal Pradesh has regularly been in media headlines for extensive cannabis cultivation and abuse of other substances. The study was conducted to provide an essential source of information about substance abuse and its correlates in this Himalayan region. MATERIALS AND METHODS This was a descriptive school-based cross-sectional study conducted among students (13-19 years studying in classes 7th to 12th. Multi-stage cluster random design and PPS sampling methodology was adopted. A sample of 3000 students both from rural and urban areas studying in 20 government and private senior secondary schools was selected. An anonymous, pretested, self-administered questionnaire adapted from WHO and ESPAD questionnaires was used to collect relevant information. Statistical analysis was done by entering the data in SPSS. RESULTS The ultimate response rate was 98.5%. Out of the total of 2864 participants, 785 (27.4%; 95%, CI 25.8% to 29.1% had indulged in substance abuse at least once in their lifetime. Prevalence of current and regular users was 13.8% (95%, CI 12.5% to 15.1% and 4.1% (95%, CI 3.4% to 4.9%, respectively. Alcohol was the most commonly abused substance among ever users at 18.1% followed by tobacco (17.6% and cannabis (6.2%. Around 85% of the students perceived indulgence in substance abuse to be harmful for health. The logistic regression model revealed that substance abuse among friends (AOR 5.32, family members (AOR 2.04, inability to spend quality time with parents (AOR 2.44, gender (AOR 1.68 and older age group of 16-19 years (AOR 1.51 were the factors found to be positively associated with substance abuse. CONCLUSION The study has brought out a high prevalence of substance abuse among the students. The participants’ high knowledge about

    We argue that moduli stabilization generically restricts the evolution following transitions between weakly coupled de Sitter vacua and can induce a strong selection bias towards inflationary cosmologies. The energy density of domain walls between vacua typically destabilizes Kahler moduli and triggers a runaway towards large volume. This decompactification phase can collapse the new de Sitter region unless a minimum amount of inflation occurs after the transition. A stable vacuum transition is guaranteed only if the inflationary expansion generates overlapping past light cones for all observable modes originating from the time of reheating, which leads to an approximately flat and isotropic universe. High scale inflation is vastly favored. Our results point towards a framework for studying parameter fine-tuning and inflationary initial conditions in flux compactifications.

    This study tests the hypothesis that adolescents with romantic partners are less similar to their friends on rates of alcohol abuse than adolescents without romantic partners. Participants (662 girls, 574 boys) ranging in age from 12 to 19 years nominated friends and romantic partners, and completed a measure of alcohol abuse. In hierarchical linear models, friends with romantic partners were less similar on rates of alcohol abuse than friends without romantic partners, especially if they were older and less accepted. Follow-up longitudinal analyses were conducted on a subsample (266 boys, 374 girls) of adolescents who reported friendships that were stable across 2 consecutive years. Associations between friend reports of alcohol abuse declined after adolescents became involved in a romantic relationship, to the point at which they became more similar to their romantic partners than to their friends.

    Full Text Available Numerous questions surround the nature of reward processing in the developing adolescent brain, particularly in regard to polysubstance use. We therefore sought to examine incentive-elicited brain activation in the context of three common substances of abuse (cannabis, tobacco, and alcohol. Due to the role of the nucleus accumbens (NAcc in incentive processing, we compared activation in this region during anticipation of reward and loss using a monetary incentive delay (MID task. Adolescents (ages 14–18; 66% male were matched on age, gender, and frequency of use of any common substances within six distinct groups: cannabis-only (n = 14, tobacco-only (n = 34, alcohol-only (n = 12, cannabis + tobacco (n = 17, cannabis + tobacco + alcohol (n = 17, and non-using controls (n = 38. All groups showed comparable behavioral performance on the MID task. The tobacco-only group showed decreased bilateral nucleus accumbens (NAcc activation during reward anticipation as compared to the alcohol-only group, the control group, and both polysubstance groups. Interestingly, no differences emerged between the cannabis-only group and any of the other groups. Results from this study suggest that youth who tend toward single-substance tobacco use may possess behavioral and/or neurobiological characteristics that differentiate them from both their substance-using and non-substance-using peers.

    The use of drugs among adolescents/youth often results in a high degree of distress for the family members who live with them. This in turn can lead to a deterioration of mental (psychological) health, hindering any attempt to successfully cope with the situation. The goal of our research was to study the effect of the Community Reinforcement and Family Training (CRAFT) program on parents of adolescents/young adult drug users. Study volunteers (n = 50) were parents from Valencia (Spain) that were divided into two groups. The experimental group (n = 25) was made up of parents whose sons and daughters exhibited problems with drug use and the constructed noncausal baseline group (n = 25) was made up of parents whose sons and daughters did not show any substance abuse problems. For both groups, self-esteem (Rosenberg Self-Esteem Scale), depression (BDI-II), anxiety (STAI), and anger (STAXI-II) were evaluated before and after the application of the CRAFT program. Results show a significant improvement in the experimental group's self-esteem, depression, and anger state and a decrease in negative moods. These changes in parents produce a positive effect on their substance-using sons and daughters: of the 25 participants, 15 contacted specialized addiction treatment resources for the first time.

    Substance and Internet use or abuse, psychopathology and suicidal ideation appear to be related. The aim of this study is to investigate the association between use of psychotropic substances, inadequate Internet use, suicidal ideation and other psychopathological symptoms within the adolescent population. The present study was carried out as part of the Saving and Empowering Young Lives in Europe (SEYLE) project, funded by the European Union. The sample is composed of 1026 adolescents aged between 14 and 16 years from 12 state schools in Asturias (530 men and 496 women). This study adds to the possibility of knowing whether the SEYLE data is confirmed in a relatively isolated and recession hit province of Spain. In the present study the following consumption rates were obtained: a) alcohol 11.89% in males and 7.86% in females; b) tobacco: 4.15% and 5.44 % in males and females respectively; c) other drugs: 6.98% in males and 4.44% in females; d) maladaptive or pathological Internet use: 14.53% and 20.77% in males and females respectively. The variables that predict suicide ideation in the logistic regression model were: previous suicide attempts, depression, maladaptive or pathological Internet use, peer problems and alcohol consumption.

    Recovery among adolescents undergoing substance abuse treatment was modeled in terms of pre-treatment motivation, therapeutic relationships, psychological functioning, treatment retention, legal pressures, DSM diagnoses, and client demographics. To address between program differences, a within-covariance matrix, based on 547 youth, was used. Applicability of the results across treatment modalities was also examined. The data were from the NIDA-sponsored DATOS Adolescent study. Results from structural equation models (estimated using Mplus) indicated that higher pre-treatment motivation predicted stronger counselor and in-treatment peer relationships, better counselor relationships and retention predicted less illegal drug use at follow-up, and DSM diagnosis was important in the treatment process. Overall, illegal drug use at follow-up was associated with post-treatment alcohol consumption, cigarette use, condom nonuse, psychological distress, criminality, and school non-attendance. The results document the importance of motivation and therapeutic relationships on recovery, even when taking into account the relative effects of legal pressures, DSM diagnoses, and demographics.

    The runaway generation during disruptions is regarded as a serious problem in future tokamak devices. The number and the high energy of these runaways can lead to considerable damage of wall components. In the TEXTOR tokamak (R{sub 0}=1.75 m, a=0.46 m; I{sub p}=350 kA, B{sub t}=2.25T, flat top time {approx_equal}2 s), low density discharges (n{sub e} < 1x10{sup 19} m{sup -3}) are analyzed to study the creation mechanism and the energy increase of the runaways. This is mainly done by the synchrotron radiation emitted by highly relativistic runaways (> 20 MeV). The general features of this synchrotron radiation will be described in Sect.2. In Sect.3 the creation rate of runaways is derived from this radiation. An intriguing observation made at the end of low density ohmic discharges is a fast increase in the pitch angle (i.e. the ratio of perpendicular to parallel velocity) from the runaways on a time scale of less than 65 {mu}s. This phenomenon is discussed in Sect.4. Finally some conclusions will be drawn on the implications these results have for future tokamak operation. (author) 4 refs., 3 figs.

    1994-08-01

    The diagnostic validity of multiple personality disorder (MPD) and its association to trauma have been questioned because corroboration of child abuse in studies of patients with MPD is scant. The purpose of this study was to determine on a retrospective basis whether external corroboration of child abuse could be found in a group of patients with MPD and dissociative disorder not otherwise specified. A group of child and adolescent psychiatric inpatients and outpatients was chosen because of the extensive number of collateral records collected on them in a tertiary care setting. This group was also chosen because of the intense interest paid by child protective services and courts to child abuse during the past 15 years. This retrospective chart review confirmed child abuse in eight of nine patients with MPD and in all 12 cases of dissociative disorder not otherwise specified. This study provides further evidence of the association of severe dissociative disorders with trauma, particularly child abuse. Future studies should be prospective and blinded to avoid the possibility of investigator bias, and should include a control group for comparison of base rate of child abuse.

  17. Some theoretical models and constructs generic to substance abuse prevention programs for adolescents: possible relevance and limitations for problem gambling.

    Evans, Richard I

    2003-01-01

    For the past several years the author and his colleagues have explored the area of how social psychological constructs and theoretical models can be applied to the prevention of health threatening behaviors in adolescents. In examining the need for the development of gambling prevention programs for adolescents, it might be of value to consider the application of such constructs and theoretical models as a foundation to the development of prevention programs in this emerging problem behavior among adolescents. In order to provide perspective to the reader, the present paper reviews the history of various psychosocial models and constructs generic to programs directed at prevention of substance abuse in adolescents. A brief history of some of these models, possibly most applicable to gambling prevention programs, are presented. Social inoculation, reasoned action, planned behavior, and problem behavior theory, are among those discussed. Some deficits of these models, are also articulated. How such models may have relevance to developing programs for prevention of problem gambling in adolescents is also discussed. However, the inherent differences between gambling and more directly health threatening behaviors such as substance abuse must, of course, be seriously considered in utilizing such models. Most current gambling prevention programs have seldom been guided by theoretical models. Developers of gambling prevention programs should consider theoretical foundations, particularly since such foundations not only provide a guide for programs, but may become critical tools in evaluating their effectiveness.

    OBJECTIVE: to analyze the factors associated with the underreporting on the part of nurses within Primary Health Care of abuse against children and adolescents. METHOD: cross-sectional study with 616 nurses. A questionnaire addressed socio-demographic data, profession, instrumentation and knowledge on the topic, identification and reporting of abuse cases. Bivariate and multivariate logistic regression was used. RESULTS: female nurses, aged between 21 and 32 years old, not married, with five or more years since graduation, with graduate studies, and working for five or more years in PHC predominated. The final regression model showed that factors such as working for five or more years, having a reporting form within the PHC unit, and believing that reporting within Primary Health Care is an advantage, facilitate reporting. CONCLUSION: the study's results may, in addition to sensitizing nurses, support management professionals in establishing strategies intended to produce compliance with reporting as a legal device that ensures the rights of children and adolescents.

    2012-10-01

    The purpose of this paper is to describe unique culturally-based factors that may increase the vulnerability of Asian American adolescents to engage in alcohol use and abuse and the role of parent-child bonding as a protective factor. In particular, this paper addresses the interactions among acculturation, alcohol use, and parent-child bonding and the challenges Asian American families face in strengthening parent-child bonds. We begin by examining likely causes for alienation that occur as a result of immigration to the United States. We then present the cultural context of Asian American families that can also serve to create distance between parent and child, including the contrasting cultural orientations of individualism and collectivism, Asian traditional values, differences in Eastern and Western parenting styles, and intergenerational cultural dissonance. Next, we present a review of the research that has examined acculturation as a risk factor for alcohol use and abuse among Asian American adolescents, with special attention to the mediating role of parent-child bonding. Finally, we conclude with recommendations for future research on the risk and protective factors for adolescent substance abuse, as well as other risky health behaviors among the growing population of Asian Americans in the United States.

    2009-03-01

    The purpose of this study was to examine the relationship between child maltreatment and adolescent binge drinking. Given that many victimized children have been maltreated in multiple ways, we examine the effects of co-occurrence of multiple types of maltreatment on adolescent binge drinking. We used the National Longitudinal Study of Adolescent Health (AddHealth), which included a nationally representative sample of adolescents (n=12,748). Adolescent binge drinking was defined as five or more drinks in a row at least 2-3 times per month in the past year. Among those reporting any maltreatment, 12.4% reported binge drinking compared to 9.9% among those reporting no maltreatment. Logistic regression models found that child maltreatment is a robust risk factor for adolescent binge drinking controlling for parental alcoholism. In particular, all types of or combinations of types of maltreatment were strongly associated with adolescent binge drinking, controlling for age, gender, race, parental alcoholism and monitoring. Research examining the effect of childhood maltreatment on later alcohol abuse needs to recognize the clustering effects of multiple types of childhood maltreatment on alcohol problems.

    2016-03-01

    This article reports results from the National Survey on Teen Relationships and Intimate Violence (STRiV) for 12- to 18-year-old youth (n = 1,804). STRiV provides the first nationally representative household survey focused on adolescent relationship abuse (ARA), covering perpetration and victimization. Among respondents (37%) reporting current- or past-year dating, 69% reported lifetime ARA victimization (63% lifetime ARA perpetration). Although psychological abuse was most common for these youth (more than 60%), the rates of sexual abuse (18%) and physical abuse victimization (18%), as well as 12% reporting perpetrating physical abuse and/or sexual abuse (12%) were substantial as well. Other than differences by age and gender, ARA rates were consistent by race/ethnicity, geographic region, urbanicity, and household characteristics, highlighting the importance of universal prevention programs. Compared with youth aged 15 to 18, those 12 to 14 years old reported lower rates of psychological and sexual ARA victimization. Similarly, we found lower ARA perpetration rates for those 12 to 14. We found no gender differences for ARA victimization but found that girls perpetrated more physical ARA than boys. Girls aged 15 to 18 reported perpetrating moderate threats/physical violence at more than twice the rate of younger girls and 3 times the rate compared with boys aged 15 to 18; girls aged 15 to 18 reported perpetrating more than 4 times the rate of serious psychological abuse than boys 15 to 18. Finally, these data document the significant positive correlation between ARA victimization and perpetration. Findings suggest that when working with youth in prevention services, interventions should not be designed for monolithic groups of "victims" or "perpetrators." © The Author(s) 2014.

    The relationships between family environment and psychological distress and between psychological distress and sleep disturbance in adolescents are well established. However, less is known about the influence of family environment on sleep disturbance. The authors' goal is to examine the effects of parental involvement on psychological distress and sleep disturbance in 34 adolescents with a history of substance abuse. Linear regression techniques and confidence intervals were used to test the significance of mediation analyses. Lower levels of parental involvement were associated with higher levels of psychological distress, and higher levels of psychological distress were associated with lower sleep efficiency and more time spent in bed. Follow-up analyses found that higher levels of parental involvement were associated with earlier morning arising times, when controlling for psychological distress. These data indicate that psychological distress is important to consider when examining the relationship between parental involvement and sleep in adolescents.

    This study examined if relationship power, sex refusal self-efficacy, and/or fear of condom negotiation mediated the relationship between abuse history and consistent condom use (CCU) among African-American female adolescents (n=593). Participants with an abuse history (58%) were less likely to report CCU (p=.003). Women with an abuse history reported less relationship power (p=.006) and self-efficacy for refusing sex (p<.001), and more fear of condom negotiation (p=.003), none of which independently or jointly mediated the association between abuse and CCU. Notably, history of abuse was associated with CCU across mediator models (p=.037 to p=.067), despite inclusion of psychosocial mediators. This study demonstrates the importance of understanding adolescents’ condom use behaviors within the context of their life experiences, especially past abuse history. PMID:25505369

    The act of adolescent suicide continues to threaten adolescent populations in New York City (NYC). Consistent positive correlations have been found between a plethora of risk factors present in NYC adolescent populations and suicidal ideations and behaviors. Psychiatric conditions that may contribute to the rate of adolescent suicide in NYC include depression, bipolar disorder, substance abuse and schizophrenia. Unique factors that have been found to contribute to increased rates of completed suicides in NYC include the phenomena of railway suicides and suicide tourism. Homelessness and income inequality in NYC have also been consistently correlated with increased suicidality; with one study finding suicide attempts reported by a significant percentage of new admissions to homeless shelters. Adolescent populations in NYC that have been identified as particularly vulnerable to suicidality include runaway youth, homosexual youth, victimized adolescents and adolescents with a recent history of posttraumatic stress disorder (PTSD). Longitudinal studies in NYC have found that physical and sexual abuse is highly predictive of adolescent suicidality, with variations by ethnic group. Currently, there is a disturbing lack of sufficient research on adolescent suicide in NYC, specifically regarding causal factors, the effects of television on suicide, comorbid suicidality and drug abuse, and cultural factors contributing to suicide. This dearth of literature may be related to the ethical problems inherent in suicide research, self reports and/or post mortem analyses.

    In recent decades, alexithymia has been considered a risk factor for multiple somatic and psychiatric conditions. Yet, whereas alexithymia has been extensively studied in adults with a substance misuse, only one study has reported data on cannabis abusers from the general population. Hence, our main objective was to explore alexithymia in a clinical sample of treatment-seeking young outpatients with a DSM-IV cannabis dependence or abuse diagnosis compared to controls. 120 young patients (95 males - mean age 17.9years (SD=2.8; 14 to 25)) with a cannabis dependence or abuse (DSM-IV-TR criteria evaluated with the MINI), seeking treatment in an addiction unit, and 110 healthy control subjects (77 males - mean age 18.2years (SD=3.4; 14 to 25)) participated in the study. They completed a battery of self-reports measuring alexithymia (TAS-20; BVAQ-B), depression (BDI-13) and state and trait anxiety (STAI). 35.3% of cannabis users were alexithymic, and logistic regression analysis showed that the alexithymic components of difficulties identifying and describing feelings combined with trait anxiety predicted group membership. This first study on young cannabis abusers and dependent subjects further emphasizes the importance of considering the affective style, and particularly the anxious temperament and alexithymia features, as factors associated with substance misuse during late adolescence.

    It has been suggested that child sexual abuse is related to poor attachment to parents, which is associated with an inability to form intimate relationships. Seto and Lalumière indicated that there were too few studies of adolescent males to determine whether poor attachment was associated with perpetration. This study was designed to follow up on a previous study and further explored the association between insecure attachment to parents, social isolation, and interpersonal adequacy to child sexual abuse perpetration in adolescents. We compared two samples of adolescent males who had committed sexual offenses, those who committed offenses against children (n = 140) and those who committed offenses against peer or adults (n = 92), with a sample of similarly aged males in treatment for mental health or substance use issues (n = 93). Data were collected using a semi-structured interview and computer-administered questionnaire. We found an indirect association between anxious attachment and sexual offenses against child victims, which was accounted for by measures of social involvement and social isolation. These involvement and isolation measures also did not have a direct association with sexual offenses against child victims, in that their contribution was accounted for by a measure of Masculine Adequacy. This Masculine Adequacy, combined with decreased levels of Sexual Preoccupation and Hypersexuality and increased Sexual Compulsivity, was associated with commission of child sexual abuse. The interpersonal variables did not enter a model predicting sexual offending against peers/adults, which seemed solely associated with the interaction between Sexual Compulsivity and Hypersexuality. © The Author(s) 2014.

    Neglectful rearing is linked with young adults' substance use and abuse, though the developmental mechanisms that underlie this association are unclear. The present study examines links between self-esteem growth during adolescence, childhood supervisory versus physical neglect severity, and substance use and abuse in young adulthood. A sample of youth was obtained from the Add Health study (N = 8738; 55.4 %-Female; 20 %-African American, 14.7 %-Hispanic). Growth mixture modeling analyses supported declining, ascending, and stable high self-esteem trajectories. The declining and ascending trajectories reported greater neglect and alcohol abuse (but not use) as well as cannabis use and abuse. The findings suggest that compromised development of self-esteem underlies associations between neglect and substance use and abuse. Preventive interventions may benefit from targeting self-esteem among neglected youth.

    The purpose of this study was to examine the moderating mediation effect of self-esteem on the relations among adolescents' abuse experiences, depression and anxiety, and suicidal ideation. The participants were selected using secondary data from a population in the 2012 Korea Welfare Panel Survey (KOWEPS). Data were analyzed using SPSS 15.0 and SPSS Macro, and bootstrapping and hierarchical regression analysis were performed to analyze multilevel models. First, analysis of the mediating effect of the adolescents' abuse showed that there was significant mediating influence between suicidal ideation and depression and anxiety. Second, hierarchical regression analysis showed that self-esteem had significant mediation effect on depression and anxiety in adolescents' suicidal ideation. Third, SPSS Macro showed that self-esteem also significantly moderated the mediating effect of adolescents' abuse experiences on suicidal ideation through depression and anxiety. The study results suggest that in future research on adolescent's abuse experience, the risk of suicide in depression and anxiety scores should be selected through evaluation of each individual's self-esteem scale. Coping strategies with immediate early intervention should be suggested.

    Full Text Available Introduction: The present study was ‎designed to evaluate the prevalence of child abuse in a child and adolescent psychiatric clinical population. Methods: This cross-sectional study was conducted in a clinical population of children and adolescents aged 8-18 years. 80 out-patients and 94 in-patients were selected according to probability proportional to size sampling. Kiddie schedule for affective disorder and schizophrenia questionnaire, a demographic questionnaire, and child abuse self-report scale were filled for each subject. Data were analyzed by using Stata software. Results: Among the out-patient subjects, 50 were male (62.5% and 30 were female (37.5%; for in-patient these subjects numbers were 76 (80.9% and 18 (19.1%, respectively. The mean age of subjects was 15.2 years in the in-patient group and 11.7 years in the out-patient group. In 66.1% of abuse cases the perpetrators were parents, 5.2% siblings, and 28.7% someone else. Among in-patient subjects, summed up prevalence rates of severe and very severe psychological abuse, neglect, physical abuse, and sexual abuse were 11.7, 33.0, 2.1, and 0.0%, respectively; for out-patient subjects these values were 3.8, 11.2, 3.8, and 0.0%, respectively. Moreover, among in-patient subjects, prevalence rates of moderate psychological abuse, neglect, physical abuse, and sexual abuse were 27.7, 27.7, 24.5, and 4.3%, respectively; and for out-patient subjects these values were 30.0, 27.5, 11.2, and 0.0%, respectively. Subjects with attention-deficit/hyperactivity disorder (ADHD suffered a higher rate of physical abuse, whereas, subjects with bipolar mood disorder (BMD suffered a higher rate of sexual abuse. Conclusion: The prevalence of child abuse is highly prevalent in children and adolescents with psychiatric disorders. It is recommended that this population be screened routinely for child abuse.

    The use of illicit drugs is currently a major medical problem among adolescents. Several illicit drugs have a high abuse potential and can be neurotoxic causing high morbidity and mortality. The clinical manifestation of adolescents with acute drug-induced neurotoxicity is often characterized by non-specific symptoms and findings. Early diagnosis is important to prevent death and permanent long-term neurological impairments. We report on clinical and neuroimaging findings in five adolescents with acute brain imaging following illicit drug intoxication to highlight the role of neuroimaging findings in the diagnostic work-up of pediatric acute drug-induced neurotoxicity. Our patients reveal two main neuroimaging patterns of brain injury: diffuse symmetric subcortical white matter injury with preferential cerebellar involvement (leukoencephalopathy pattern) or multiple foci of ischemic infarctions in a non-arterial territory distribution (ischemic pattern). Familiarity with these two neuroimaging patterns of findings in the evaluation of magnetic resonance imaging studies in adolescents with acutely altered mental status may suggest the correct diagnosis, narrow the differential diagnosis, and consequently allow early initiation of targeted laboratory investigations and treatment, potentially improving outcome.

    Electronic communication technology (ECT), such as mobile phones and online communication tools, is widely used by adolescents; however, the availability of such tools may have both positive and negative impacts within the context of romantic relationships. While an established literature has documented the nature, prevalence, and impact of traditional forms of adolescent dating violence and abuse (ADVA), limited empirical investigation has focused on the role of ECT in ADVA or what shall be termed technology-assisted adolescent dating violence and abuse (TAADVA) and how adolescents perceive the impact of TAADVA relative to ADVA. In this article, the authors explore the role ECT plays in adolescent romantic relationships and psychologically abusive and controlling ADVA behaviors and its perceived impact. An opportunity sample of 52 adolescents (22 males and 30 females) between the ages of 12 and 18 years participated in the study. One all-female and seven mixed-gendered semi-structured focus groups were conducted. Thematic analysis was used to identify three superordinate themes, including (a) perceived healthy versus unhealthy communication, (b) perceived monitoring and controlling communication, and (c) perceived impact of technology-assisted abuse compared with that in person. While ECTs had a positive impact on the development and maintenance of adolescent romantic relationships, such tools also provided a new avenue for unhealthy, harassment, monitoring, and controlling behaviors within these relationships. ECT was also perceived to provide unique impacts in terms of making TAADVA seem both less harmful and more harmful than ADVA experienced in person. Adolescents' perceptions and experiences of ECT in romantic relationships and TAADVA may also vary be gender. Implications of the findings are discussed, and recommendations are made for future research.

    The dynamic ergodic divertor (DED) of TEXTOR has been applied to runaway discharges. The runaway electrons (ɛ < 30 MeV) are developed as probes for investigating the internal magnetic field line structure in the plasma. Complementary diagnostics are used, namely neutron measurements for the loss of the runaways and synchrotron radiation for the detection inside the plasma. During the DED phase, three features of the runaway electrons are found: a sudden loss from the just formed ergodic layer, an enhanced diffusive transport and very sudden loss events which may be related to field line reconnection processes.

    1995-02-03

    Runaway electrons are inherently present in a tokamak, in which an electric field is applied to drive a toroidal current. The experimental work is performed in the tokamak TEXTOR. Here runaway electrons can acquire energies of up to 30 MeV. The runaway electrons are studied by measuring their synchrotron radiation, which is emitted in the infrared wavelength range. The studies presented are unique in the sense that they are the first ones in tokamak research to employ this radiation. Hitherto, studies of runaway electrons revealed information about their loss in the edge of the discharge. The behaviour of confined runaways was still a terra incognita. The measurement of the synchrotron radiation allows a direct observation of the behaviour of runaway electrons in the hot core of the plasma. Information on the energy, the number and the momentum distribution of the runaway electrons is obtained. The production rate of the runaway electrons, their transport and the runaway interaction with plasma waves are studied. (orig./HP).

    2005-01-01

    Sexual abuse in childhood can disable self-esteem, self-concept, relationships, and ability to trust. It can also leave psychological trauma that compromises a boy's confidence in adults. While some boys who willingly participate may adjust to sexual abuse, many others face complications, such as reduced quality of life, impaired social relationships, less than optimal daily functioning, and self-destructive behavior. These problems can respond to treatment if detected. In this paper, we examine the prevalence, characteristics, psychological consequences, treatment, and coping patterns of boys who have been sexually abused and their failure to disclose abuse unless asked during a therapeutic encounter. Nurses have a responsibility to detect the clues to sexual abuse, diagnose the psychological consequences, and advocate for protection and treatment. Computerized literature search of the Medline and PsychInfo literature and books on sexual abuse of boys. Psychological responses to abuse such as anxiety, denial, self-hypnosis, dissociation, and self-mutilation are common. Coping strategies may include being the angry avenger, the passive victim, rescuer, daredevil, or conformist. Sexual abuse may precipitate runaway behavior, chronic use of sick days, poor school or job performance, costly medical, emergency and or mental health visits. In worst cases, the boy may decide that life is not worth living and plan suicide. The nurse has a key role to play in screening, assessing, and treating sexual abuse children.

FONTES DE DADOS: Revisão da literatura nacional e internacional através do MEDLINE e LILACS, utilizando como palavras-chave "abuso" e "violência sexual" (1988 a 2005, aliada à experiência clínica dos autores. SÍNTESE DOS DADOS: O abuso sexual tem um impacto muito grande na saúde física e mental da criança e do adolescente, deixando marcas em seu desenvolvimento, com danos que podem persistir por toda vida. Sua detecção precoce possibilita o tratamento e acompanhamento adequados, com a minimização das seqüelas. O envolvimento familiar deve ser levado em conta. Todas as distorções de relacionamento necessitam ser avaliadas e tratadas, para que se interrompa sua continuidade, que se dará no abuso intergeracional e na possibilidade de revitimização. A identificação da violência doméstica e dos sinais de alerta físicos e psicológicos para o abuso sexual fazem parte da avaliação. CONCLUSÕES: Todo pediatra precisa estar apto a decodificar os sinais e sintomas que a criança e o adolescente vítimas de abuso sexual trazem consigo. Necessita ser proficiente na escuta, no exame clínico e no tratamento. Deve estar capacitado para o manejo psicológico da situação de violência e ter conhecimento da legislação e meios de proteção legais e sociais existentes em sua comunidade, sempre necessários na assistência às vitimas de abuso sexual.OBJECTIVE: To review single aspects, which involve sexual abuse in childhood and adolescence, giving subsidies for accurate diagnosis and management, emphasizing the short and long-term consequences.

    2013-02-01

    We used a longitudinal twin design to examine selection effects of personality traits at age 11 on high-risk environmental contexts at age 14 and the extent to which these contexts mediated risk for substance abuse at age 17. Socialization at age 11 (willingness to follow rules and endorse conventional values) predicted exposure to contextual risk at age 14. Contextual risk partially mediated the effect of socialization on substance abuse, though socialization also had a direct effect. In contrast, boldness at age 11 (social engagement and assurance, thrill seeking, and stress resilience) also predicted substance abuse directly but was unrelated to contextual risk. There was substantial overlap in the genetic and shared environmental influences on socialization and contextual risk, and genetic risk in socialization contributed to substance abuse indirectly via increased exposure to contextual risk. This suggests that active gene-environment correlations related to individual differences in socialization contributed to an early, high-risk developmental trajectory for adolescent substance abuse. In contrast, boldness appeared to index an independent and direct genetic risk factor for adolescent substance abuse.

  19. Cannabis abuse in adolescence and the risk of psychosis: a brief review of the preclinical evidence.

    Science.gov (United States)

    Rubino, T; Parolaro, D

    2014-07-03

    Epidemiological studies suggest that Cannabis use during adolescence confers an increased risk for developing psychotic symptoms later in life. However, despite their interest, the epidemiological data are not conclusive, due to their heterogeneity; thus modeling the adolescent phase in animals is useful for investigating the impact of Cannabis use on deviations of adolescent brain development that might confer a vulnerability to later psychotic disorders. Although scant, preclinical data seem to support the presence of impaired social behaviors, cognitive and sensorimotor gating deficits as well as psychotic-like signs in adult rodents after adolescent cannabinoid exposure, clearly suggesting that this exposure may trigger a complex behavioral phenotype closely resembling a schizophrenia-like disorder. Similar treatments performed at adulthood were not able to produce such phenotype, thus pointing to a vulnerability of the adolescent brain towards cannabinoid exposure. The neurobiological substrate of the adolescent vulnerability is still largely unknown and experimental studies need to elucidate the cellular and molecular mechanism underlying these effects. However, the few data available seem to suggest that heavy adolescent exposure to cannabinoids is able to modify neuronal connectivity in specific brain areas long after the end of the treatment. This is likely due to disruption of maturational events within the endocannabinoid system during adolescence that in turn impact on the correct neuronal refinement peculiar of the adolescent brain, thus leading to altered adult brain functionality and behavior.

    Full Text Available Background: Children are one of the most vulnerable groups of the society and are constantly threatened by different people in their family or society. The aim of this study was investigating the correlation of child abuse with personality features and high risk behavior in high school students of Islamshahr, Iran. Methods: This study cross-sectional analytical was conducted on the high school girls and boys of Islamshahr in spring 2014.528 students were selected by cluster random sampling among 4 high schools (two female and two male high schools. Childhood trauma questionnaire, NEO-Five Factor Inventory and Youth Risk-Taking Scale were used for data collection. Data were analyzed by independence t-test, Pearson's correlation coefficient and multiple linear regression. Results: The results of independence t-test indicated significant differences between girls and boys in terms of child abuse and high risk experience (t=-2.16,p=0.03 and t=-5.03, P=0.001, respectively. Also, the results demonstrated a significant relationship between child abuse and personality characteristics, high risk behavior and all its subscales (P<0.05. The findings of multiple linear regressionindicated that child abuse could explain 14% total risk-taking, 25% neurotic personality feature , 14% extroversion, 10% agreeableness, 1% flexibility and 13% conscientiousness (P<0.05. Conclusion: According to the research findings, appropriate behavior with children is of great importance. Therefore, child abuse would form inappropriate personality features and increase risk behaviors among children.

    Childhood sexual trauma has been demonstrated to increase survivors' risk for engaging in unrestricted sexual behaviors and experiencing adolescent sexual assault. The current study used the sexual self-schema construct to examine cognitive representations of sexuality that might drive these behavioral patterns. In Study 1 (N = 774), we attempted to improve the content validity of the Sexual Self Schema Scale for child sexual abuse (CSA) survivors, introducing a fourth sexual self-schema factor titled the "immoral/irresponsible" factor. In Study 2 (N = 1150), the potential differences in sexual self-views, as assessed by the four sexual self-schema factors, between CSA survivors and non-victims were explored. In addition, Study 2 evaluated how these sexual self-schema differences may contribute to participation in unrestricted sexual behaviors and risk for sexual assault in adolescence. Results indicated that a history of CSA impacted the way women viewed themselves as a sexual person on each of the four factors. CSA survivors were found to view themselves as more open and possessing more immoral/irresponsible cognitions about sexuality as compared to women who did not have a CSA history. In addition, the CSA survivors endorsed less embarrassment and passionate/romantic views of their sexual selves. The interaction of CSA severity and the sexual self-schemas explained variance in adolescent sexual assault experiences above and beyond the severity of CSA history and participation in risky sexual behaviors. The findings suggest that sexual self-views may serve to moderate the relationship between CSA and adolescent sexual assault. Implications of these findings and directions for future research are discussed.

  4. Runaway Stars in Supernova Remnants

    Half of all stars and in particular 70 % of the massive stars are a part of a multiple system. A possible development for the system after the core collapse supernova (SN) of the more massive component is as follows: The binary is disrupted by the SN. The formed neutron star is ejected by the SN kick whereas the companion star either remains within the system and is gravitationally bounded to the neutron star, or is ejected with a spatial velocity comparable to its former orbital velocity (up to 500 km/s). Such stars with a large peculiar space velocity are called runaway stars. We present our observational results of the supernova remnants (SNRs) G184.6-5.8, G74.0-8.5 and G119.5+10.2. The focus of this project lies on the detection of low mass runaway stars. We analyze the spectra of a number of candidates and discuss their possibility of being the former companions of the SN progenitor stars. The spectra were obtained with INT in Tenerife, Calar Alto Astronomical Observatory and the University Observatory Jena. Also we investigate the field stars in the neighborhood of the SNRs G74.0-8.5 and G119.5+10.2 and calculate more precise distances for these SNRs.

    Supernova Propels Companion Star through Interstellar Space The following success story is a classical illustration of scientific progress through concerted interplay of observation and theory. It concerns a 35-year old mystery which has now been solved by means of exciting observations of a strange double star. An added touch is the successive involvement of astronomers connected to the European Southern Observatory. For many years, astronomers have been puzzled by the fact that, among the thousands of very young, hot and heavy stars which have been observed in the Milky Way, there are some that move with exceptionally high velocities. In some cases, motions well above 100 km/sec, or ten times more than normal for such stars, have been measured. How is this possible? Which mechanism is responsible for the large amounts of energy needed to move such heavy bodies at such high speeds? Could it be that these stars are accelerated during the powerful explosion of a companion star as a supernova? Such a scenario was proposed in 1961 by Adriaan Blaauw [1], but until now, observational proof has been lacking. Now, however, strong supporting evidence for this mechanism has become available from observations obtained at the ESO La Silla observatory. The mysterious runaway stars OB-runaway stars [2] are heavy stars that travel through interstellar space with an anomalously high velocity. They have been known for several decades, but it has always been a problem to explain their high velocities. Although most OB-runaway stars are located at distances of several thousands of lightyears, their high velocity results in a measurable change in position on sky photos taken several years apart. The velocity component in the direction of the Earth can be measured very accurately from a spectrogram. From a combination of such observations, it is possible to measure the space velocity of OB-runaways. Bow shocks reveal runaway stars It has also been found that some OB-runaways display

    This study is first of its kind in Bangkok, and is a five-year (2009-2013) cross-sectional web-based survey to examine HIV preventive behaviors related to substance abuse among adolescents (N = 16,913). The questionnaire was self-administered. Logistic regression was used to analyze the data. The relationship between different types of substance abuse with risky and preventive behaviors was assessed. Male participants reported more substance abuse as compared to females. The risk behaviors observed among the substance abusers include increased sexual experience, multiple sex partners, no use of condoms, and injection drug use. The preventive behaviors include having a high self-risk assessment, going for HIV testing (highest in methamphetamine users), and screening for sexually transmitted infection. Logistic regression suggests that risky behaviors (e.g., sexual experience, injection drug use) are more common in substance abusers. Adolescents are clearly at a high risk. Behavioral preventive measures are needed to reduce or delay premature substance exposure to prevent a wide range of health problems and risks such as HIV and AIDS, injection drug use and unprotected sex.

    Abuse during early life, especially from the caregiver, increases vulnerability to develop later-life psychopathologies such as depression. Although signs of depression are typically not expressed until later life, signs of dysfunctional social behavior have been found earlier. How infant abuse alters the trajectory of brain development to produce pathways to pathology is not completely understood. Here we address this question using two different but complementary rat models of early-life abuse from postnatal day 8 (P8) to P12: a naturalistic paradigm, where the mother is provided with insufficient bedding for nest building; and a more controlled paradigm, where infants undergo olfactory classical conditioning. Amygdala neural assessment (c-Fos), as well as social behavior and forced swim tests were performed at preweaning (P20) and adolescence (P45). Our results show that both models of early-life abuse induce deficits in social behavior, even during the preweaning period; however, depressive-like behaviors were observed only during adolescence. Adolescent depressive-like behavior corresponds with an increase in amygdala neural activity in response to forced swim test. A causal relationship between the amygdala and depressive-like behavior was suggested through amygdala temporary deactivation (muscimol infusions), which rescued the depressive-like behavior in the forced swim test. Our results indicate that social behavior deficits in infancy could serve as an early marker for later psychopathology. Moreover, the implication of the amygdala in the ontogeny of depressive-like behaviors in infant abused animals is an important step toward understanding the underlying mechanisms of later-life mental disease associated with early-life abuse.

    This article describes the increasing risks of use of marijuana and related products by adolescents. As THC content increases and methods such as "dabbing" increase frequency of use, risks of marijuana use as perceived by youth are decreasing. At a time when marijuana access is increasing nationally, a new marijuana landscape is forming in which both adolescents and treatment providers must adjust their perceptions of what was once thought of as a "harmless" drug. This article describes this new landscape, and what it may mean for adolescent drug treatment.

    The way emotions are regulated might affect the engagement on risk behaviors in adolescents and young adults. Therefore, studying the relationship between these variables could be of great importance. Some of the less studied risky behaviors are pathological gambling, and Internet and videogame abuse. This research aims to analyze the existing relationship between such risky behaviors, emotion regulation, and dysfunctional psychological symptomatology (depression, anxiety, phobic anxiety, somatization, obsessive-–compulsive behavior, interpersonal sensitivity, hostility, paranoid ideation, and psychoticism). In addition, it also looks to assess whether emotional regulation plays a mediating role between pathological gambling, and Internet and videogame abuse, and psychological symptomatology. The sample was composed of 1312 young adults and adolescents, aged between 12 and 30, recruited from scholar centers, universities and free time groups, and from associations and centers associated with FEJAR (Spanish Federation of Rehabilitated Gamblers). Participants completed measurements of impulsive behavior, emotion regulation, and dysfunctional symptomatology. Results showed that there is generally a positive and significant relation between these variables. Moreover, it has been pointed out that emotion regulation mediates the association between impulsive behavior and dysfunctional symptomatology among those young adults and adolescents who engage in these impulsive behaviors, except for the relation between videogame abuse and depressive symptomatology. Training in emotional regulation skills could be useful in dealing with and treating this type of behaviors in adolescents and young adults.

    Reports an error in "Neurobehavioral markers of resilience to depression amongst adolescents exposed to child abuse" by Meg J. Dennison, Margaret A. Sheridan, Daniel S. Busso, Jessica L. Jenness, Matthew Peverill, Maya L. Rosen and Katie A. McLaughlin (Journal of Abnormal Psychology, 2016[Nov], Vol 125[8], 1201-1212). In the article there was an error in the title. The word "Adolescents" was singular. The online version of this article has been corrected. (The following abstract of the original article appeared in record 2016-52992-014.) Childhood maltreatment is strongly associated with depression, which is characterized by reduced reactivity to reward. Identifying factors that mitigate risk for depression in maltreated children is important for understanding etiological links between maltreatment and depression as well as improving early intervention and prevention. We examine whether high reward reactivity at behavioral and neurobiological levels is a marker of resilience to depressive symptomology in adolescence following childhood maltreatment. A sample of 59 adolescents (21 with a history of maltreatment; Mean Age = 16.95 years, SD = 1.44) completed an fMRI task involving passive viewing of emotional stimuli. BOLD signal changes to positive relative to neutral images were extracted in basal ganglia regions of interest. Participants also completed a behavioral reward-processing task outside the scanner. Depression symptoms were assessed at the time of the MRI and again 2 years later. Greater reward reactivity across behavioral and neurobiological measures moderated the association of maltreatment with baseline depression. Specifically, faster reaction time (RT) to cues paired with monetary reward relative to those unpaired with reward and greater BOLD signal in the left pallidum was associated with lower depression symptoms in maltreated youth. Longitudinally, greater BOLD signal in the left putamen moderated change in depression scores over time, such that

A scanning interferometer diagnostic has been used to analyze the time evolution of the RE beam radial position and its instabilities. Correspondence of the interferometer time traces, radial profile reconstructed via magnetic measurements and fission chamber signals are discussed. New RE control algorithms, which define in real-time updated plasma current and position references, have been tested in two experimental scenarios featuring disruption generated RE plateaus: the experimental data confirm the effectiveness of the control strategies as the RE beam interaction with the plasma facing components is reduced while the current is ramped-down.

    2011-12-01

    Full Text Available The principal aim of this study was to provide a current description of the child and teenager maltreatment phenomenon in the Buenos Aires Province. The sample was composed by 5341 cases of children and teenagers from 0 to 20 years old, whose were treated in 2010 for having been victims of maltreatment. Physical maltreatment was the most frequent one. The girls presented major proportion of sexual abuse, whereas boys registered major proportions of negligence, physical maltreatment and desertion situation. An increase of the sexual abuse frequency in teenagers from 12 years was observed. As a whole, the information demonstrates that sex and age of victims are differentially associated with different types of maltreatment, and these are pertinent variables to have into account by future investigations, and prevention and protection organisms.

    Emerging adulthood is the period of greatest risk for problematic substance use. The primary aim of the current study was to examine the relationship between a broad measure of child maltreatment and several key outcomes for a large clinical sample of emerging adults (n = 858) and adolescents (n = 2,697). The secondary aim was to examine the extent to which the relationship between child maltreatment and treatment outcomes differed between emerging adults and adolescents. Multilevel latent growth curve analyses revealed emerging adults and adolescents who experienced child maltreatment reported significantly greater reductions over time on several treatment outcomes (e.g., substance use, substance-related problems, and emotional problems). Overall, analyses did not support differential relationships between child maltreatment and changes over time in these substance use disorder treatment outcomes for emerging adults and adolescents. The one exception was that although emerging adults with child maltreatment did reduce their HIV risk over time, their improvements were not as great as were the improvements in HIV risk reported by adolescents who had experienced child maltreatment. © The Author(s) 2014.

    Full Text Available Sexual abuse is defined as use of child or adolescent by the adults for satisfying of sexual urges and needs with forcing, threatening or tricking. Sexual abuse can be in the form of sexual abuse without touch, sexual touch, interfemoral intercourse, sexual penetration, and sexual exploitation. The prevalence of sexual abuse is reported as 10-40%. It is seen in female four times more than in males. Abusers are frequently male, only 5-15% of them are female. The abuse by females is usually towards male child. Thirty-fifty percent of abuse cases among child and adolescent are outside the family including strangers or familiar person. Some features of abusers are introvert personality, pedophilic and antisocial personality. Most of the abusers have a history of sexual abuse or aggression during childhood. Sexual intercourse between two people who are not allowed to marry by law is called as incest. Family pattern of incest is defined globally as disorganized and dysfunctional. The most commonly reported familial pattern is rigid and patriarchal family pattern with a harsh father using force quite frequently. The clinical features and impacts of the sexual abuse on the child varies according to the relation between abusers and the child, form of abuse, duration of abuse, presence of physical assault, developmental phase, child age and psychological development before the abuse. Sexual abuse history may result in psychiatric disorders including anxiety, depression, substance dependence, suicide act, borderline personality disorder, posttraumatic stress disorder. Abuse negatively affects interpersonal relationships and self esteem of abused individuals. Several studies reported close association between risky sexual behaviors in adulthood and a history of of sexual abuse during childhood. Four traumatic dynamics including traumatic sexuality with abuse, feeling of betrayal, weakness, and stigmatization exist in childhood abuse. Trauma can cause

    Full Text Available Abstract Background Substance abuse among adolescents is a major public health and social problem. However, studies rarely investigate the relationships between substance abuse, educational achievement and sport factors. Substance abuse is an even more significant problem in societies that have experienced trauma, such as Bosnia and Herzegovina, which have had recent wars. The aims of this study were to investigate substance abuse among adolescents in Bosnia and Herzegovina and to study the potential gender-specific relationships between a sport factors (physical activity/exercise/athletic participation and substance abuse and b scholastic achievement and substance abuse. Methods Our sample consisted of 1,032 adolescents who were 17 to 18 years old (435 boys and 597 girls and who were in the final grade of high school. These subjects were randomly selected from the territory of Herzegovina-Neretva Canton of Bosnia and Herzegovina. Retrospective testing was performed using an extensive self-administered questionnaire. The questionnaire included questions involving topics such as sociodemographic variables, scholastic variables, sport factors, and substance abuse data (smoking habits, drugs consumption and alcohol consumption using the AUDIT questionnaire. Descriptive statistics, frequencies, analyses of the differences and correlational analyses were performed. Results Our results found that greater than one-third of the boys and one-fourth of the girls were daily smokers, and almost half of the boys and one-fifth of the girls practiced harmful drinking; other drugs (i.e. heroin, cocaine, amphetamines, etc. were rarely consumed. Boys dominated in sport factors, whereas girls were more successful in scholastic achievement. Approximately 23% of the boys and 6% of the girls reported that they practiced harmful drinking and smoked simultaneously.

    Full Text Available Problem statement: Incarcerated youth with borderline symptomatology represent a particularly at risk-population due to their enggement in risky behaviors. Five hundred twenty two adolescents were assessed for borderline symptomatology (MACI, engagement in risky behaviors and attitudes/knowledge. Approach:Adolescents were divided into two groups: low borderline (below the 60 scale score cutoff and high borderline (subclinical and clinical range. Multivariate analyses were used to test for group differences. Results: The high borderline group had higher perceived susceptibility, greater knowledge, less favorable sexual and condom attitudes and less favorable behavioral intentions. There were no significant differences by group on sexual risk or substance use behaviors. A subset (n = 156 participating in a risk reduction experimental trial were followed three months post-intervention for differences in sexual risk and substance use. The high borderline experimental participants reported significantly more anal sex than the low borderline adolescents at 3 month follow-up. High borderline adolescents in the control group reported greater cocaine use than low borderline controls at 3 months, including trends suggesting more marijuana and alcohol use. At 3 month follow-up, no differences in cocaine, alcohol or marijuana use were detected between high and low borderline adolescents in the experimental group. Adolescents with higher borderline tendencies appear to realistically assess that they are at high risk of contracting HIV but may have less confidence in their ability to adopt HIV preventive behaviors. The results indicate that borderline personality symptoms may represent an important indicator of attitudes conducive to HIV transmission. Conclusion:Three-month follow-up data indicate the importance of examining borderline characteristics more microanalytically within research studies, including

    This study aimed to examine the pathways from child sexual abuse to sexual assault victimization and perpetration in adolescence and early adulthood, considering risky sexual behavior and lowered sexual self-esteem as mediator variables. In a two-wave longitudinal study with 2251 college students in Germany, male and female participants provided reports of sexual aggression victimization and perpetration since age 14 (T1) and again a year later (T2), covering the last 12 months. In addition, child sexual abuse (CSA; before the age of 14), risky sexual behavior, and sexual self-esteem were assessed at T1, and risky sexual behavior and sexual-self-esteem were assessed again at T2. Experience of CSA was significantly associated with greater likelihood of sexual aggression victimization and perpetration, lower sexual self-esteem, and more risky sexual behavior in both gender groups at T1 and was directly related to victimization at T2 among male participants. In both gender groups, CSA indirectly contributed to a higher probability of sexual victimization at T2 via its impact on victimization T1. In males, the indirect path from CSA to T2 perpetration via T1 perpetration was also significant. Through its negative impact on sexual self-esteem, CSA indirectly increased the probability of sexual victimization among women and the probability of sexual aggression perpetration among men. Risky sexual behavior mediated the pathway from CSA to sexual victimization at T2 for men and women and the pathway from CSA to sexual aggression perpetration for women. The findings contribute to the understanding of gendered effects of CSA on revictimization and the victim-to-perpetrator cycle. Copyright © 2016 Elsevier Ltd. All rights reserved.

    It has been estimated that as many as 12%-15% of the nations 63 million children are in need of mental health treatment. We have a responsibility to do everything we can to see to it that these children receive the services they need. Unfortunately, there is mounting evidence that a significant proportion of our health care resources are being misspent on the unnecessary and inappropriate hospitalization of children and youths in psychiatric and substance abuse treatment programs. More alarming is the evidence of poor quality programs, abusive practices, and greed. The intense competition to capture a "share of the market" and turn a profit or keep a nonprofit hospital from closing its doors is contributing to unprofessional and unethical advertising and public relations practices. In the end these practices will reflect poorly on the broader mental health and health care community. Hopefully, the stakeholders in the system will recognize these problems and assume a leadership role in turning the situation around. If not, we can expect intervention from forces outside the system (e.g., courts, elected public officials, public interest groups, the business community, and child advocates).

    Bullying is endemic in the nation's schools and takes a substantial toll on its victims' physical and social-emotional well-being. We assessed the association between specific reasons for which adolescents believe that they are targeted for bullying and their rates of various types of substance use by analyzing the association between self-reported past 30-day substance use and past 30-day bullying victimization among 53,750 middle and high school students in Oregon. Our results confirm previous estimates of prevalence rates for bullying as well as modest (r bullying victimization and substance use. However, study findings did not reveal a particular reason for bullying victimization that would place adolescents at a relatively high risk of substance use.

    We present an overview of FTU experiments on runaway electron (RE) generation and control carried out through a comprehensive set of real-time (RT) diagnostics/control systems and newly installed RE diagnostics. An RE imaging spectrometer system detects visible and infrared synchrotron radiation. A Cherenkov probe measures RE escaping the plasma. A gamma camera provides hard x-ray radial profiles from RE bremsstrahlung interactions in the plasma. Experiments on the onset and suppression of RE show that the threshold electric field for RE generation is larger than that expected according to a purely collisional theory, but consistent with an increase due to synchrotron radiation losses. This might imply a lower density to be targeted with massive gas injection for RE suppression in ITER. Experiments on active control of disruption-generated RE have been performed through feedback on poloidal coils by implementing an RT boundary-reconstruction algorithm evaluated on magnetic moments. The results indicate that the slow plasma current ramp-down and the simultaneous reduction of the reference plasma external radius are beneficial in dissipating the RE beam energy and population, leading to reduced RE interactions with plasma facing components. RE active control is therefore suggested as a possible alternative or complementary technique to massive gas injection.

  10. Desire to dissociate: implications for problematic drinking in college students with childhood or adolescent sexual abuse exposure.

    Alcohol use to replace inadequate dissociative capabilities, or chemical dissociation, has been linked to college students with childhood or adolescent sexual abuse (CASA). Insofar as CASA-exposed persons experience a restricted range of dissociative capabilities, what remains relatively unclear is whether some desire to achieve greater dissociative experiences. Nonclinical levels of dissociative tendencies have positively predicted alcohol-related blackouts in CASA-exposed students, and dissociation mediated the relations between CASA and intoxication frequency. Although alcohol (similar to dissociation) can reduce physiological and psychological responses to stress, alcohol consumption may be prompted by a desire to dissociate rather than inadequate dissociative tendencies alone. To investigate this interpretation of the chemical dissociation phenomenon, researchers examined the mediating potential of dissociative tendencies using the Dissociative Experiences Scale-II (DES-II) as well as the desire to dissociate concept (ie, a modified version of the DES-II) on the relations between CASA exposure and problematic alcohol use in college students (N = 298). Results indicated that dissociation scores did not replicate previous mediation findings whereas desire to dissociate scores fully mediated CASA exposure and problematic alcohol use. Implications of the results are discussed including possible reasons why prior mediation results were not replicated as well as links to experiential avoidance.

    This study examines intentions to take protective action against peer sexual harassment and abuse (PSHA). The theory of planned behavior (TPB) proposes that attitudes about protective action, perceptions of what others would think about doing this (subjective norms), and behavioral control would be important predictors. A total of 1,531 Chinese secondary school students (769 boys and 762 girls) from Hong Kong were surveyed to test this model. Results showed that the TPB model was predictive for girls, but only subjective norms and behavioral control significantly predicted boys' intentions to protect themselves. Results supported the influence of subjective norms and perceived behavioral control on youths' intentions to reject PSHA. These factors may be useful in guiding the development of an educational program for prevention of PSHA.

    Alcohol and substance dependency are complex, problematic phenomena, which are growing worldwide. In particular, drug use and abuse among young people is a significant concern. Although addiction presents as a problem of dependent individuals, families are also profoundly affected by the family member's addiction. In this narrative literature review, we review published research from 1937 to 2014 to capture a narrative and historical perspective of addiction and family. We condense and analyze the experiences of parents with alcohol- and drug-dependent children, to emphasize the need for a more specific, in-depth exploration of mothers' experiences. Such exploration may advance nurses' understandings of individual, familial, and social complexities of parenting an addicted child.

    Full Text Available Drug abuse is reported to be on the increase among young persons using illicit substances but little is known about the frequency with which they occur, the symptoms on presentation to health institutions, and the different substances abused. To establish this, we reviewed patient data collected at Al-Amal Hospital in Jeddah Kingdom of Saudi Arabia on young persons who are refered to the hospital for problems related to drug abuse. Data on 69 adolescent drug users were reviewed and analyzed using the Composite International Diagnostic Interview - Substance Abuse Model (CIDI-SAM to assess dependence on substances including amphetamines, cannabis, cocaine, and opioids. Furthermore, we assessed the adolescents’ data on history of delusions and hallucinations in the context of use of, or withdrawal from, these specific substances. Our analysis shows that 10 to 79.6% of users of amphetamines, cannabis, cocaine, and opiates met DSM-III-R dependence criteria for each specific substance. The prevalence of psychotic symptoms associated with each specific substance ranged from users with no diagnosis to users with severe dependence as follows: amphetamines (3-100%, cannabis (7- 60.0%, cocaine (5-70.7%, and opiates (4- 88%. The risk of psychotic symptoms increased for respondents who abused (OR=7.2 or had mild (OR=8.1, moderate (OR=20.0, or severe dependence (OR=14.0 on cocaine when compared to those who were users with no diagnosis. A similar pattern was evident in cannabis, opiate, and amphetamine users. In conclusion, most adolescent drug users in Saudi Arabia who are dependent on illicit substances experience psychotic symptoms in the context of use of, or withdrawal from, these substances. Psychotic symptoms increased with the severity of the disorders associated with use of all four substances. These findings underscore the importance of developing services to target this population; a population at risk of developing psychotic symptoms.

    As lithium-ion battery technologies mature, the size and energy of these systems continues to increase (> 50 kWh for EVs); making safety and reliability of these high energy systems increasingly important. While most material advances for lithium-ion chemistries are directed toward improving cell performance (capacity, energy, cycle life, etc.), there are a variety of materials advancements that can be made to improve lithium-ion battery safety. Issues including energetic thermal runaway, electrolyte decomposition and flammability, anode SEI stability, and cell-level abuse tolerance continue to be critical safety concerns. This report highlights work with our collaborators to develop advanced materials to improve lithium-ion battery safety and abuse tolerance and to perform cell-level characterization of new materials.

    Childhood maltreatment is strongly associated with depression, which is characterized by reduced reactivity to reward. Identifying factors that mitigate risk for depression in maltreated children is important for understanding etiological links between maltreatment and depression as well as improving early intervention and prevention. We examine whether high reward reactivity at behavioral and neurobiological levels is a marker of resilience to depressive symptomology in adolescence following childhood maltreatment. A sample of 59 adolescents (21 with a history of maltreatment; Mean Age = 16.95 years, SD = 1.44) completed an fMRI task involving passive viewing of emotional stimuli. BOLD signal changes to positive relative to neutral images were extracted in basal ganglia regions of interest. Participants also completed a behavioral reward-processing task outside the scanner. Depression symptoms were assessed at the time of the MRI and again 2 years later. Greater reward reactivity across behavioral and neurobiological measures moderated the association of maltreatment with baseline depression. Specifically, faster reaction time (RT) to cues paired with monetary reward relative to those unpaired with reward and greater BOLD signal in the left pallidum was associated with lower depression symptoms in maltreated youth. Longitudinally, greater BOLD signal in the left putamen moderated change in depression scores over time, such that higher levels of reward response were associated with lower increases in depression over time among maltreated youths. Reactivity to monetary reward and positive social images, at both behavioral and neurobiological levels, is a potential marker of resilience to depression among adolescents exposed to maltreatment. These findings add to a growing body of work highlighting individual differences in reactivity to reward as a core neurodevelopmental mechanism in the etiology of depression.

    Childhood sexual abuse is a major social problem in Africa including Ethiopia. Moreover, little has been explored about the pattern of childhood sexual abuse in the context of high school students in Ethiopia in general and in Arbaminch town in particular. Thus, the present study aims to assess the prevalence and associated factors of childhood sexual abuse among adolescent female high school students in Arbaminch town. A school- based, cross-sectional study was conducted among adolescent female high school students in Arbaminch town from 3(rd) to 8(th) March 2014. Both quantitative and qualitative methods of data collection were used. For the quantitative data, a simple random sampling technique was used to select 369 female students from grade ten of the six high schools. A pre-tested, self-administered questionnaire was used to collect the data and then analysis was made using SPSS version 20 statistical packages. For the qualitative component, fourteen in-depth interviews were conducted and analysed based on the thematic areas. The prevalence of life time rape among adolescent female high school students in Arbaminch town was 11 %. The odds of experiencing life time rape was higher among students who lived alone (AOR = 4.30; 95 % CI: 1.81, 10.24) and among students who lived with their friends (AOR = 3.31; 95 % CI: 1.23, 8.89) than those lived with their parents. The chance of experiencing rape among students who have had no open discussions with their parents about sexuality and reproductive health was higher (AOR = 2.93; 95 % CI: 1.33, 6.45) than those who have had discussions. This study revealed high levels of childhood sexual abuse among the adolescent female high school students in Arbaminch town. Ever having a discussion about sexuality and reproductive health with parents, living arrangement of the student, and father's educational status had statistically significant association with childhood sexual abuse.

    2016-08-01

    The breakup of magnetic surfaces is a central feature of ITER planning for the avoidance of damage due to runaway electrons. Rapid thermal quenches, which lead to large accelerating voltages, are thought to be due to magnetic surface breakup. Impurity injection to avoid and to mitigate both halo and runaway electron currents utilizes massive gas injection or shattered pellets. The actual deposition is away from the plasma center, and the breakup of magnetic surfaces is thought to spread the effects of the impurities across the plasma cross section. The breakup of magnetic surfaces would prevent runaway electrons from reaching relativistic energies were it not for the persistence of non-intercepting flux tubes. These are tubes of magnetic field lines that do not intercept the walls. In simulations and in magnetic field models, non-intercepting flux tubes are found to persist near the magnetic axis and in the cores of magnetic islands even when a large scale magnetic surface breakup occurs. As long as a few magnetic surfaces reform before all of the non-intercepting flux tubes dissipate, energetic electrons confined and accelerated in these flux tubes can serve as the seed electrons for a transfer of the overall plasma current from thermal to relativistic carriers. The acceleration of electrons is particularly strong because of the sudden changes in the poloidal flux that naturally occur in a rapid magnetic relaxation. The physics of magnetic islands as non-intercepting flux tubes is studied. Expressions are derived for (1) the size of islands required to confine energetic runaway electrons, (2) the accelerating electric field in an island, (3) the increase or reduction in the size of an island by the runaway electron current, (4) the approximate magnitude of the runaway current in an island, and (5) the time scale for the evolution of an island.

    This paper reviews the physiology of menstrual abnormalities in the adolescent and suggests a management protocol based on this pathophysiological framework. Initial discussion covers the physiology of puberty and menstruation. Menstrual abnormalities occur often in the adolescent. Excessive bleeding is the most dramatic symptom, but the most common complaints concern the frequency, duration, and variability of menstrual flow. Often the oral contraceptive (OC) pill is the panacea for the patient, her family, and the physician. This solution has several advantages. It is attractive, inexpensive, easy to use, and regulates the menstrual cycle. Although menstrual abnormalities are seemingly corrected, the treatment is not physiological. This use of the OC pill may mask the underlying problem and delay the diagnosis of a medical disorder and will interfere with the normal maturation of the hypothalamic-pituitary-ovarian axis, which is necessary for regular menses to occur. The diagnosis of anovulatory bleeding is one of exclusion. Both local and systemic problems can mimic dysfunctional bleeding. Pregnancy must always be considered but is often overlooked in the young teenager. A satisfactory history and physical examination, including a vaginal and/or rectal examination, is paramount to rule out other causes. Coagulation defects may play a significant role in adolescent bleeding abnormalities. Endocrine disorders, including thyroid disease, Cushing's syndrome, hypoprolactinemia, and acromegaly, can result in menstrual abnormalities. After a meticulous history and physical examination, any teenager presenting with abnormal vaginal bleeding should not exhibit any physical abnormality other than the signs and symptoms of blood loss. The initial laboratory tests need not be extensive but must include a hemoglobin estimation, blood smear, platelet count, bleeding time, prothrombin time, partial thromboplastin time, and thyroid function tests.

In the framework of the clinical and psychological (non-clinical levels psychological consequences of CSA in accordance with the psychic state of victims were revealed. 4 groups of consequences with different intensity are described: psychogenic state in form of disorder (1 and psychogenic state in form of reaction (2 (clinical level; unfavorable psychological state (3 and minimally unfavorable state (4 (psychological level. It was stated that the more severe is the victim’s psychic disturbance, from minimally unfavorable to psychic disorder, the broader is the range of psychological, personality spheres involved the bigger is the number and the intensity of symptoms of posttraumatic reactions. Psychological consequences displayed by mentally healthy victims of CSA indicate, though, their quality of life impairment.

    2017-06-01

    A self-consistent analysis of the relevant physics regarding the formation and termination of runaway beams during mitigated disruptions by Ar and Ne injection is presented for selected ITER scenarios with the aim of improving our understanding of the physics underlying the runaway heat loads onto the plasma facing components (PFCs) and identifying open issues for developing and accessing disruption mitigation schemes for ITER. This is carried out by means of simplified models, but still retaining sufficient details of the key physical processes, including: (a) the expected dominant runaway generation mechanisms (avalanche and primary runaway seeds: Dreicer and hot tail runaway generation, tritium decay and Compton scattering of γ rays emitted by the activated wall), (b) effects associated with the plasma and runaway current density profile shape, and (c) corrections to the runaway dynamics to account for the collisions of the runaways with the partially stripped impurity ions, which are found to have strong effects leading to low runaway current generation and low energy conversion during current termination for mitigated disruptions by noble gas injection (particularly for Ne injection) for the shortest current quench times compatible with acceptable forces on the ITER vessel and in-vessel components ({τ\\text{res}}∼ 22~\\text{ms} ). For the case of long current quench times ({τ\\text{res}}∼ 66~\\text{ms} ), runaway beams up to  ∼10 MA can be generated during the disruption current quench and, if the termination of the runaway current is slow enough, the generation of runaways by the avalanche mechanism can play an important role, increasing substantially the energy deposited by the runaways onto the PFCs up to a few hundreds of MJs. Mixed impurity (Ar or Ne) plus deuterium injection proves to be effective in controlling the formation of the runaway current during the current quench, even for the longest current quench times, as well as in decreasing

    Full Text Available Abstract: Background: Childhood sexual abuse (CSA is a substantial global health and human rights problem and consequently a growing concern in sub-Saharan Africa. We examined the association between individual and community-level socioeconomic status (SES and the likelihood of reporting CSA. Methods: We applied multiple multilevel logistic regression analysis on Demographic and Health Survey data for 6,351female adolescents between the ages of 15 and 18 years from six countries in sub-Saharan Africa, between 2006 and 2008. Results: About 70% of the reported cases of CSA were between 14 and 17 years. Zambia had the highest proportion of reported cases of CSA (5.8%. At the individual and community level, we found that there was no association between CSA and socioeconomic position. This study provides evidence that the likelihood of reporting CSA cut across all individual SES as well as all community socioeconomic strata. Conclusions: We found no evidence of socioeconomic differentials in adolescents’ experience of CSA, suggesting that adolescents from the six countries studied experienced CSA regardless of their individual- and community-level socioeconomic position. However, we found some evidence of geographical clustering, adolescents in the same community are subject to common contextual influences. Further studies are needed to explore possible effects of countries’ political, social, economic, legal, and cultural impact on childhood sexual abuse.

    Sundown Ranch, a residential behavioral health care treatment facility for adolescents, tracked the progress and results of treatment by selecting performance measures from a psychosocial screening inventory. The temper scale was one of the two highest scales at admission and the highest scale at discharge. A clinical performance improvement (PI) project was conducted to assess improvements in clients' ability to manage anger after the incorporation of Rational Emotive Behavior Therapy (REBT) into treatment. Eighteen months of baseline data (July 1, 1999 - February 1, 2001) were collected, and 20 months of data (May 1, 2001 - December 31, 2002) were collected after the introduction of the PI activity. In all, data were collected for 541 consecutive admissions. A comparison of five successive quarterly reviews indicated average scores of 1.4 standard deviations (SDs) above the mean on the temper scale before the PI activity and .45 SD above the mean after. The performance threshold of reduction of the average temper scale score to < or =1 SD was met for 17 of 20 months. The fact that the PI activity reduced the temper scale elevations by almost one full SD is highly suggestive of the efficacy of REBT with the treatment population. After the project was completed, REBT was promoted as an additional therapeutic modality within the treatment program.

    2010-12-01

    This review considers the precise role played by runaway breakdown (RB) in the initiation and development of lightning discharges. RB remains a fundamental research topic under intense investigation. The question of how lightning is initiated and subsequently evolves in the thunderstorm environment rests in part on a fundamental understanding of RB and cosmic rays and the potential coupling to thermal runaway (as a seed to RB) and conventional breakdown (as a source of thermal runaways). In this paper, we describe the basic mechanism of RB and the conditions required to initiate an observable avalanche. Feedback processes that fundamentally enhance RB are discussed, as are both conventional breakdown and thermal runaway. Observations that provide clear evidence for the presence of energetic particles in thunderstorms/lightning include γ-ray and X-ray flux intensifications over thunderstorms, γ-ray and X-ray bursts in conjunction with stepped leaders, terrestrial γ-ray flashes, and neutron production by lightning. Intense radio impulses termed narrow bipolar pulses (or NBPs) provide indirect evidence for RB particularly when measured in association with cosmic ray showers. Our present understanding of these phenomena and their enduring enigmatic character are touched upon briefly.

RESULTS: significant statistic results were found. 90.8% of the adolescents were victims of rape, and 46.5% of the children suffered sexual assault. The presupposed violence (PV was more frequent in the group of children (63.4% and a serious threat in the group of adolescents (63.2%. Innocentia consilli was exclusive PV among 100% of children and 59.5% of adolescents. 84.5% of children were molested by identifiable abusers, most frequently family members. Perpetrators were unknown in 72.3% of the cases of adolescent abuse. 42.3% of sexual abuse of children occurred in their homes, and 28.2% at the abuser's. Adolescents were approached during daily activities (34.8% and on their way to work or school (28.4%. Most patients did not have genital or extragenital trauma. CONCLUSIONS: children suffered sexual assault, perpetrated by a known abuser through presupposed violence in private places. Adolescents were raped by unknown individuals, under serious threat, in nondomestic places.

  13. Abuse behavior of high-power, lithium-ion cells

    Spotnitz, R.; Franklin, J.

    Published accounts of abuse testing of lithium-ion cells and components are summarized, including modeling work. From this summary, a set of exothermic reactions is selected with corresponding estimates of heats of reaction. Using this set of reactions, along with estimated kinetic parameters and designs for high-rate batteries, models for the abuse behavior (oven, short-circuit, overcharge, nail, crush) are developed. Finally, the models are used to determine that fluorinated binder plays a relatively unimportant role in thermal runaway.

    Improved understanding of runaway-electron formation and decay processes are of prime interest for the safe operation of large tokamaks, and the dynamics of the runaway electrons during dynamical scenarios such as disruptions are of particular concern. In this paper, we present kinetic modelling of scenarios with time-dependent plasma parameters; in particular, we investigate hot-tail runaway generation during a rapid drop in plasma temperature. With the goal of studying runaway-electron generation with a self-consistent electric-field evolution, we also discuss the implementation of a conservative collision operator and demonstrate its properties. An operator for avalanche runaway-electron generation, which takes the energy dependence of the scattering cross section and the runaway distribution into account, is investigated. We show that the simpler avalanche model of Rosenbluth & Putvinskii [Nucl. Fusion 37, 1355 (1997)] can give very inaccurate results for the avalanche growth rate (either lower or hig...

    A new method to obtain the runaway probability and the expected slowing-down time for runaway electrons is developed, by solving the adjoint Fokker-Planck equation in momentum space. The runaway probability function has a smooth transition at the runaway separatrix, which can be attributed to the effect of the pitch angle scattering term in the kinetic equation. The expected slowing-down time gives a new way to estimate the runaway current decay time in experiments. The result shows that the decay rate of high energy electron is very slow when E is close to the critical electric field, which helps elucidate the hysteresis effect seen in the runaway electron population. Given the same numerical accuracy, the new method is more efficient than the Monte Carlo simulation.

  16. On the Production of Relativistic Runaway Electrons in Damavand Tokamak

    2013-02-01

    Experimental observations in Damavand tokamak show that hard X-ray is produced by either disruption with I p 20 kA. Hard X-ray also persists from the initiation of plasma discharge to the end. Occurrence of multiple spikes in hard X-ray during the discharge is evident. The propagation of hard X-ray is attributed to runaway electrons. We observe runaway electrons in two regimes with different characteristics. Regime (RADI) is similar to the observations of other Tokamak during disruption on that the plasma current is reduced abruptly and interpreted by Dreicer theory. In the regime of RADII, hard X-ray and subsequently runaway electrons are observed from starting of plasma discharge which provides the condition that the most of runaway electrons contain the toroidal plasma current. Runaway electron beam excites whistler waves and scattered electrons in velocity space and prevent growing the runaway electrons beam.

    2015-01-01

    Ions accelerated by electric fields (so-called runaway ions) in plasmas may explain observations in solar flares and fusion experiments, however limitations of previous analytic work have prevented definite conclusions. In this work we describe a numerical solver of the 2D non-relativistic linearized Fokker-Planck equation for ions. It solves the initial value problem in velocity space with a spectral-Eulerian discretization scheme, allowing arbitrary plasma composition and time-varying electric fields and background plasma parameters. The numerical ion distribution function is then used to consider the conditions for runaway ion acceleration in solar flares and tokamak plasmas. Typical time scales and electric fields required for ion acceleration are determined for various plasma compositions, ion species and temperatures, and the potential for excitation of toroidal Alfv\\'en eigenmodes during tokamak disruptions is considered.

    The influence of magnetic turbulence on runaway transport has been studied. The evolution of runaway distribution function has been calculated using Electra a 2D code in momentum space and 1D in radius coordinate. The code considers the effect of averaging the turbulence by runaway orbits.

    During pellet injection and supersonic molecular beam injection, we have observed the increase of electron density and the enhancement of hard x-ray radiation, but the runaway electrons normally decrease without additional fuelling when the density of plasma increases. This phenomenon may come from the synergetic effects of Dreicer and avalanche runaway electrons. The experimental results are consistent with the calculation based on the theory of avalanche runaway in the HL-1M tokamak.

    Runaway electrons are a promising tool to study magnetic turbulence in tokamak plasma. Recently, several studies have been devoted to this issue. In these studies hard X-rays, created when runaways hit the limiter, have been analysed. This paper also addresses the question of confinement of runaways. Here, however, not the runaways leaving the plasma are studied, but the runaways in the interior. They were diagnosed by means of the infrared synchrotron radiation which relativistic runaways (> 10 MeV) emit, as shown by Finken et al. With this tool information can be obtained about runaway - confinement times, energy, birth-rate, dimensions of the runaway beam and perhaps about their energy distribution. In this paper, at first a presentation of the measurements is given and the energy and pitch angle is deduced from the data. Then a comparison of the runaway confinement in low density plasmas (n[sub e](0) < 0.8 10[sup 19] m[sup -3]) is made for three different conditions; normal ohmic discharge, discharge with a gas puff and one with neutral beam injection (NBI).

  1. Generation of runaway electrons during the thermal quench in tokamaks

    Aleynikov, Pavel; Breizman, Boris N.

    2017-04-01

    This work provides a systematic description of electron kinetics during impurity dominated thermal quenches. A Fokker–Planck equation for the hot electrons and a power balance equation for the bulk plasma are solved self-consistently, with impurity radiation as the dominant energy loss mechanism. We find that runaway production is facilitated by heavy injection of impurities up to prompt conversion of the total current into a sub-MeV runaway current. We also find that runaway formation is less efficient in plasmas with high pre-quench temperatures and predict significant radial variation of the runaway seed in such plasmas.

    Full Text Available Introduction:Attention deficit hyperactivity disorder (ADHD is a neuropsychiatric pathology that has an important prevalence among young people and is difficult to diagnose. It is usually treated with methylphenidate, a psychostimulant with a mechanism of action similar to that of cocaine. Previous studies show that repeated use of psychostimulants during childhood or adolescence may sensitize subjects, making them more prone to later abuse of psychostimulant drugs such as cocaine and methamphetamine.Objective: To review experimental studies in non-human models (rodents and monkeys treated with methylphenidate during infancy or adolescence and tested for reinforcing effects on psychostimulant drugs in adulthood.Method: Systematic collection of data was performed on four databases (Web of Knowledge, PsycARTICLE, PubMed and SciELO. The initial search identified 202 articles published from 2009 to 2014, which were screened for eligibility. Seven articles met the inclusion criteria and were reviewed in this study.Results: The findings indicate that early exposure to methylphenidate has an effect on an ADHD animal model, specifically, on spontaneously hypertensive strain rats, especially those tested using the self-administration paradigm.Conclusion:Future studies should prioritize the spontaneously hypertensive rat strain - an animal model of ADHD. Experimental designs comparing different behavioral paradigms and modes of administration using this strain could lead to improved understanding of the effects of exposure to methylphenidate during childhood and adolescence.

  5. A backward Monte Carlo method for efficient computation of runaway probabilities in runaway electron simulation

    Science.gov (United States)

    Zhang, Guannan; Del-Castillo-Negrete, Diego

    2016-10-01

    Kinetic descriptions of RE are usually based on the bounced-averaged Fokker-Planck model that determines the PDFs of RE in the 2 dimensional momentum space. Despite of the simplification involved, the Fokker-Planck equation can rarely be solved analytically and direct numerical approaches (e.g., continuum and particle-based Monte Carlo (MC)) can be time consuming specially in the computation of asymptotic-type observable including the runaway probability, the slowing-down and runaway mean times, and the energy limit probability. Here we present a novel backward MC approach to these problems based on backward stochastic differential equations (BSDEs). The BSDE model can simultaneously describe the PDF of RE and the runaway probabilities by means of the well-known Feynman-Kac theory. The key ingredient of the backward MC algorithm is to place all the particles in a runaway state and simulate them backward from the terminal time to the initial time. As such, our approach can provide much faster convergence than the brute-force MC methods, which can significantly reduce the number of particles required to achieve a prescribed accuracy. Moreover, our algorithm can be parallelized as easy as the direct MC code, which paves the way for conducting large-scale RE simulation.

    Victims of child abuse and neglect are more likely to develop emotional and behavioral problems than their non-abused peers. In many cases they do not receive evidence based treatments. Based on pilot studies and clinical experience, a structured and manualized case-management protocol was developed to provide child welfare professionals guidance, direction and support in helping these families find and engage in appropriate treatment. The protocol is described. A survey among child welfare workers indicates a lack of knowledge about mental disorders in victims of child abuse as well as an insufficient cooperation between the child welfare and the mental healthcare system. Child welfare workers who have applied the manual evaluate it positively. This study shows that the structured case-management can be implemented in a child welfare setting.

We show that the simplified avalanche model of Rosenbluth and Putvinskii (1997 Nucl. Fusion 37 1355) can give inaccurate results for the avalanche growth rate (either lower or higher) for many parameters, especially when the average runaway energy is modest, such as during the initial phase of the avalanche multiplication. The developments presented pave the way for improved modelling of runaway-electron dynamics during disruptions or other dynamic events.

  11. Runaway electron drift orbits in magnetostatic perturbed fields

    Science.gov (United States)

    Papp, G.; Drevlak, M.; Fülöp, T.; Helander, P.

    2011-04-01

    Disruptions in large tokamaks can lead to the generation of a relativistic runaway electron beam that may cause serious damage to the first wall. To mitigate the disruption and suppress the runaway beam the application of resonant magnetic perturbations has been suggested. In this work we investigate the effect of resonant magnetic perturbations on the confinement of runaway electrons by simulating their drift orbits in magnetostatic perturbed fields and calculating the orbit losses for various initial energies and magnetic perturbation magnitudes. In the simulations we use a TEXTOR-like configuration and solve the relativistic, gyro-averaged drift equations for the runaway electrons including synchrotron radiation and collisions. The results indicate that runaway electrons are well confined in the core of the device, but the onset time of runaway losses closer to the edge is dependent on the magnetic perturbation level and thereby can affect the maximum runaway current. However, the runaway current damping rate is not sensitive to the magnetic perturbation level, in agreement with experimental observations.

    Full Text Available Objective: It is now generally known that undergoing a sexual abuse may lead to self-destruction, suicide, post-traumatic stress disorder (PTSD, depression and dissociative disorders. Our study aims at determining the rate of self-destruction and suicide among children who had experienced sexual abuse and determining the rates of depression, PTSD and dissociative disorders and their relationships each other. Materials and Methods: The children aged 0-18 who had undergone sexual abuse and sent to Prevention of Child Abuse, Application and Research Center at Erciyes University between 01.01.2011-31.12.2011 to have a judicial report were analyzed retrospectively with regard to their age, sex, frequency of abuse, psychiatric diagnosis according to DSM IV-TR and leaving home or suicide behaviors. The children were made to complete Depression Scale for Children (CDI, Child Post-Traumatic Stress Reaction Index (RPTS-CS and Dissociation Questionnaire (DIS-Q. Results: 556 cases were included in our research. There was suicide attempt in 24(4,3% of them, 15 (2,7% had the behavior of self-mutilation, 6 (1,1% of them had the idea to commit suicide.

    2015-09-01

    The dynamics of high energy runaway electrons is analyzed for plasmas with high impurity content. It is shown that modified collision terms are required in order to account for the collisions of the relativistic runaway electrons with partially stripped impurity ions, including the effect of the collisions with free and bound electrons, as well as the scattering by the full nuclear and the electron-shielded ion charge. The effect of the impurities on the avalanche runaway growth rate is discussed. The results are applied, for illustration, to the interpretation of the runaway electron behavior during disruptions, where large amounts of impurities are expected, particularly during disruption mitigation by massive gas injection. The consequences for the electron synchrotron radiation losses and the resulting runaway electron dynamics are also analyzed.

    The production of runaway massive binaries offers key insights into the evolution of close binary stars and open clusters. The stars HD 14633 and HD 15137 are rare examples of such runaway systems, and in this work we investigate the mechanism by which they were ejected from their parent open cluster, NGC 654. We discuss observational characteristics that can be used to distinguish supernova ejected systems from those ejected by dynamical interactions, and we present the results of a new radio pulsar search of these systems as well as estimates of their predicted X-ray flux assuming that each binary contains a compact object. Since neither pulsars nor X-ray emission are observed in these systems, we cannot conclude that these binaries contain compact companions. We also consider whether they may have been ejected by dynamical interactions in the dense environment where they formed, and our simulations of four-body interactions suggest that a dynamical origin is possible but unlikely. We recommend further X-ra...

    2011-01-01

    The incident in the LHC in September 2008 occurred in an interconnection between two magnets of the 13 kA dipole circuit. This event was traced to a defect in one of the soldered joints between two superconducting cables stabilized by a copper busbar. Further investigation revealed defective joints of other types. A combination of (1) a poor contact between the superconducting cable and the copper stabilizer and (2) an electrical discontinuity in the stabilizer at the level of the connection can lead to an unprotected quench of the busbar. Once the heating power in the unprotected superconducting cable exceeds the heat removal capacity a thermal run-away occurs, resulting in a fast melt-down of the non-stabilized cable. We have performed a thorough investigation of the conditions upon which a thermal run-away in the defect can occur. To this aim, we have prepared heavily instrumented samples with well-defined and controlled defects. In this paper we describe the experiment, and the analysis of the data, and w...

    In the blooming field of exoplanetary science, NASA's Kepler Space Telescope has revolutionized our understanding of exoplanets. Kepler's very precise and long-duration photometry is ideal for detecting planetary transits around Sun-like stars. The forthcoming Transiting Exoplanet Survey Satellite (TESS) is expected to continue Kepler's legacy. Along with transits, the Doppler technique remains an invaluable tool for discovering planets. The next generation of spectrographs, such as G-CLEF, promise precision radial velocity measurements. In this paper, we explore the possibility of detecting planets around hypervelocity and runaway stars, which should host a very compact system as consequence of their turbulent origin. We find that the probability of a multiplanetary transit is 10-3 ≲ P ≲ 10-1. We therefore need to observe ∼10-1000 high-velocity stars to spot a transit. However, even if transits are rare around runaway and hypervelocity stars, the chances of detecting such planets using radial velocity surveys is high. We predict that the European Gaia satellite, along with TESS and the new-generation spectrographs G-CLEF and ESPRESSO, will spot planetary systems orbiting high-velocity stars.

    Calorimetric measurements of the total runaway electron energy are carried out using a reciprocating probe during induced TEXTOR disruptions. A comparison with the energy inferred from runaway energy spectra, which are measured with a scintillator probe, is used as an independent check of the results. A typical runaway current of 100 kA at TEXTOR contains 30 to 35 kJ of runaway energy. The dependencies of the runaway energy on the runaway current, the radial probe position, the toroidal magnetic field and the predisruptive plasma current are studied. The conversion efficiency of the magnetic plasma energy into runaway energy is calculated to be up to 26%.

  4. On the inward drift of runaway electrons in plateau regime

    CERN Document Server

    Hu, Di

    2016-01-01

    The well observed inward drift of current carrying runaway electrons during runaway plateau regime after disruption is studied by considering the phase space dynamic of runaways in a large aspect ratio toroidal system. We consider the case where the toroidal field is unperturbed and the toroidal symmetry of the system is preserved. The invariance of canonical angular momentum in such system requires runaways to drift horizontally in configuration space for any given change in momentum space. The dynamic of this drift can be obtained by taking the variation of canonical angular momentum. It is then found that runaway electrons will always drift inward as long as they are decelerating. This drift motion is essentially non-linear, since the current is carried by runaways themselves, and any runaway drift relative to the magnetic axis will cause further displacement of the axis itself. A simplified analytical model is constructed to describe such inward drift both in ideal wall case and no wall case, and the runa...

  5. One-Dimensional Modelling of Marine Current Turbine Runaway Behaviour

    Directory of Open Access Journals (Sweden)

    Staffan Lundin

    2016-04-01

    Full Text Available If a turbine loses its electrical load, it will rotate freely and increase speed, eventually achieving that rotational speed which produces zero net torque. This is known as a runaway situation. Unlike many other types of turbine, a marine current turbine will typically overshoot the final runaway speed before slowing down and settling at the runaway speed. Since the hydrodynamic forces acting on the turbine are dependent on rotational speed and acceleration, turbine behaviour during runaway becomes important for load analyses during turbine design. In this article, we consider analytical and numerical models of marine current turbine runaway behaviour in one dimension. The analytical model is found not to capture the overshoot phenomenon, while still providing useful estimates of acceleration at the onset of runaway. The numerical model incorporates turbine wake build-up and predicts a rotational speed overshoot. The predictions of the models are compared against measurements of runaway of a marine current turbine. The models are also used to recreate previously-published results for a tidal turbine and applied to a wind turbine. It is found that both models provide reasonable estimates of maximum accelerations. The numerical model is found to capture the speed overshoot well.

  6. The relentless past: The effect of chronic sexual abuse in childhood on fifty years of adolescent and adult development.

    Four sisters, now in their late fifties and early sixties, were sexually abused during childhood over a four-year span by the same priest. Until recently they told no one about their experience and never received any psychological diagnostic evaluations or treatment. The author conducted detailed psychiatric evaluations of each of the four women while serving as the plaintiffs' expert witness during their lawsuits against the Catholic Church. The suits have been settled, and the women have given written permission to tell their stories. This unique clinical material provides a rare opportunity to describe and understand the ongoing, pervasive effects of untreated, chronic childhood sexual abuse on developmental processes over half a century. In each instance the women were describing the details of the abuse and the effects on their development for the first time. The severity of the pathology and the intense shame and anxiety associated with discussing their experiences after so many years raises questions about the choice of treatment and technique, particularly in regard to transference and countertransference issues.

    Full Text Available Runaway electrons present an important part of the present efforts in nuclear fusion research with respect to the potential damage of the in-vessel components. The COMPASS tokamak a suitable tool for the studies of runaway electrons, due to its relatively low vacuum safety constraints, high experimental flexibility and the possibility of reaching the H-mode D-shaped plasmas. In this work, results from the first experimental COMPASS campaign dedicated to runaway electrons are presented and discussed in preliminary way. In particular, the first observation of synchrotron radiation and rather interesting raw magnetic data are shown.

    Many disruptions in the Tokamak Fusion Test Reactor (TFTR) (Meade and the TFTR Group 1991 Proc. Int. Conf. on Plasma Physics and Controlled Nuclear Fusion (Washington, DC, 1990) vol 1 (Vienna: IAEA) pp 9-24) produced populations of runaway electrons which carried a significant fraction of the original plasma current. In this paper, we describe experiments where, following a disruption of a low-beta, reversed-shear plasma, currents of up to 1 MA carried mainly by runaway electrons were controlled and then ramped down to near zero using the ohmic transformer. In the longer lasting runaway plasmas, events resembling Parail-Pogutse instabilities were observed.

    The transport of runaway electrons in a high-temperature plasma is relatively easy to measure in a steady state experiment and a perturbation experiment, which provides runaway electron diffusion coefficient Dr. This diffusion coefficient is determined by internal magnetic fluctuations, so it can be interpreted in terms of a magnetic fluctuation level. The internal magnetic fluctuation level (br/BT) is estimated to be about (2-4)×-4 in the HL-1M plasma. The results presented here demonstrate the effectiveness of using runaway electron transport techniques to determine internal magnetic fluctuations. A profile of magnetic fluctuation level in the HL-1M plasma can be estimated from Dr.

  10. Runaway massive stars from R136: VFTS 682 is very likely a "slow runaway"

    Banerjee, Sambaran; Oh, Seungkyung

    2011-01-01

    We conduct a theoretical study on the ejection of runaway massive stars from R136 --- the central massive, star-burst cluster in the 30 Doradus complex of the Large Magellanic Cloud. Specifically, we investigate the possibility of the very massive star (VMS) VFTS 682 being a runaway member of R136. Recent observations of the above VMS, by virtue of its isolated location and its moderate peculiar motion, have raised the fundamental question whether isolated massive star formation is indeed possible. We perform the first realistic N-body computations of fully mass-segregated R136-type star clusters in which all the massive stars are in primordial binary systems. These calculations confirm that the dynamical ejection of a VMS from a R136-like cluster, with kinematic properties similar to those of VFTS 682, is common. Hence the conjecture of isolated massive star formation is unnecessary to account for this VMS. Our results are also quite consistent with the ejection of 30 Dor 016, another suspected runaway VMS f...

  11. Project Runaway: Calibrating the Spectroscopic Distance Scale Using Runaway O and Wolf-Rayet Stars

    Hartkopf, William I.; Mason, B. D.

    2009-05-01

    Well-determined O star masses are notoriously difficult to obtain, due to such factors as broad spectral lines, larger and less-reliable average distances, high multiplicity rates, crowded fields, and surrounding nebulosity. Some of these difficulties are reduced for the subset of O stars known as runaways, however. They have escaped some of the nebulosity and crowding, and the event leading to their ejection virtually guarantees that these objects are either single stars or extremely hard spectroscopic binaries. The goal of this project is to increase the sample of known runaway stars, using updated proper motions from the soon-to-be-released UCAC3 catalog, as well as published radial velocities and data from recent duplicity surveys of massive stars using AO and speckle interferometry. Input files include the Galactic O Star Catalog of Maiz-Apellaniz et al. (2004 ApJSS 151, 103) as well as the Seventh Catalogue of Galactic Wolf-Rayet Stars and its more recent Annex (van der Hucht 2001 NewAR 45, 135; 2006 A&A 458, 453). The new runaway star sample will form the basis for a list of SIM targets aimed at improving the distances of Galactic O and WR stars, calibrating the spectroscopic distance scale and leading to more accurate mass estimates for these massive stars.

    Peculiar phenomena were observed during experiments with runaway electrons: rapid changes in the synchrotron spot and its intensity that coincided with stepwise increases in the electron cyclotron emission (ECE) signal (cyclotron radiation of suprathermal electrons). These phenomena were initially observed in TEXTOR (Tokamak Experiment for Technology Oriented Research), where these events only occurred in the current decay phase or in discharges with thin stable runaway beams at a q = 1 drift surface. These rapid changes in the synchrotron spot were interpreted by the TEXTOR team as a fast pitch angle scattering event. Recently, similar rapid changes in the synchrotron spot and its intensity that coincided with stepwise increases in the non-thermal ECE signal were observed in the EAST (Experimental Advanced Superconducting Tokamak) runaway discharge. Runaway electrons were located around the q = 2 rational magnetic surface (ring-like runaway electron beam). During the EAST runaway discharge, stepwise ECE signal increases coincided with enhanced magnetohydrodynamic (MHD) activity. This behavior was peculiar to this shot. In this paper, we show that these non-thermal ECE step-like jumps were related to the abrupt growth of suprathermal electrons induced by bursting electric fields at reconnection events during this MHD plasma activity. Enhancement of the secondary runaway electron generation also occurred simultaneously. Local changes in the current-density gradient appeared because of local enhancement of the runaway electron generation process. These current-density gradient changes are considered to be a possible trigger for enhancement of the MHD plasma activity and the rapid changes in runaway beam behavior.

    The analysis of Li-ion secondary cells under outstanding conditions, as overcharge and high temperatures, is important to determine thermal abuse characteristics of electroactive materials and precise risk assessments on Li-ion cells. In this work, the thermal runaway behavior of LiCoO2 and LiMn2O4 cathode materials were compared at different state of charges (SOCs), including overcharge, by carrying out accelerating rate calorimetry (ARC) measurements using 18650 Li-ion cells. Onset temperatures of self-heating reactions and thermal runaway behavior were identified, and by using these onset points thermal mapping plots were made. We were able to identify non-self-heating, self-heating and thermal runaway regions as a function of state of charge and temperature. The cell using LiMn2O4 cathode material was found to be more thermally stable than the cell using LiCoO2. In parallel with the ARC measurements, the electrochemical behavior of the cells was monitored by measuring the OCV and internal resistance of the cells. The electrochemical behavior of the cells showed a slightly dependency on SOC.

    Postulating that the NMSSM singlet is a meson of a microscopic confining theory opens up new model-building possibilities. Based on this, we construct calculable models of direct mediation that solve the {mu}/B{mu} problem and simultaneously lead to realistic phenomenology. The singlet that couples to the Higgs fields develops a runaway produced by soft interactions, then stabilized by a small superpotential perturbation. The mechanism is first realized in an O'Raifeartaigh model of direct gauge mediation with metastable supersymmetry breaking. Focusing then on the microscopic theory, we argue that super QCD with massless and massive flavors in the free magnetic phase gives rise to this dynamics in the infrared. A deformation of the SQCD superpotential leads to large spontaneous R-symmetry breaking, gaugino masses naturally at the scale of the Higgs mass parameters, and absence of CP violating phases.

  15. Transits Probabilities Around Hypervelocity and Runaway Stars

    2016-01-01

    In the blooming field of exoplanetary science, NASA's Kepler Space Telescope has revolutionized our understanding of exoplanets. Kepler's very precise and long-duration photometry is ideal for detecting planetary transits around Sun-like stars. The forthcoming Transiting Exoplanet Survey Satellite (TESS) is expected to continue Kepler's legacy. In this paper, we explore the possibility of detecting planetary transits around hypervelocity and runaway stars, which should host a very compact system as consequence of their turbulent origin. We find that the probability of a multi-planetary transit is $10^{-3}\\lesssim P\\lesssim 10^{-1}$. We therefore need to observe $\\sim 10-1000$ high-velocity stars to spot a transit. We predict that the European Gaia satellite, along with TESS, could spot such transits.

    2016-10-01

    The Langevin approach to the kinetics of a collisional plasma is developed for relativistic electrons such as runaway electrons in tokamak plasmas. In this work, we consider Coulomb collisions between very fast, relativistic electrons and a relatively cool, thermal background plasma. The model is developed using the stochastic equivalence of the Fokker-Planck and Langevin equations. The resulting Langevin model equation for relativistic electrons is an stochastic differential equation, amenable to numerical simulations by means of Monte-Carlo type codes. Results of the simulations will be presented and compared with the non-relativistic Langevin equation for RE electrons used in the past.

  17. Runaway evaporation for optically dressed atoms

    Wilkowski, David

    2010-01-01

    Forced evaporative cooling in a far-off-resonance optical dipole trap is proved to be an efficient method to produce fermionic- or bosonic-degenerated gases. However in most of the experiences, the reduction of the potential height occurs with a diminution of the collision elastic rate. Taking advantage of a long-living excited state, like in two-electron atoms, I propose a new scheme, based on an optical knife, where the forced evaporation can be driven independently of the trap confinement. In this context, the runaway regime might be achieved leading to a substantial improvement of the cooling efficiency. The comparison with the different methods for forced evaporation is discussed in the presence or not of three-body recombination losses.

    2013-05-03

    The particular electric pulse discharges are observed in thunderclouds during the initiation stage of negative cloud-to-ground lightning. The discharges are quite different from conventional streamers or leaders. A detailed analysis reveals that the shape of the pulses is determined by the runaway breakdown of air in the thundercloud electric field initiated by extensive atmospheric showers (RB-EAS). The high amplitude of the pulse electric current is due to the multiple microdischarges at hydrometeors stimulated and synchronized by the low-energy electrons generated in the RB-EAS process. The series of specific pulse discharges leads to charge reset from hydrometeors to the free ions and creates numerous stretched ion clusters, both positive and negative. As a result, a wide region in the thundercloud with a sufficiently high fractal ion conductivity is formed. The charge transport by ions plays a decisive role in the lightning leader preconditioning.

    2012-01-01

    Since 2008, it has been recognised by most health authorities worldwide that the abuse of newly-emerging psychoactive drugs, ('designer drugs'/'legal highs'; DD), in youth is a rapidly increasing problem, especially in the EU, threatening to offset gains made in tackling established and illegal drugs which they are intended to mimic; DD diversity is continually increasing to circumvent laws. The aim of the study was to determine the scale of DD abuse/availability amongst Polish youth. The surveyed test population was randomly selected from a representative group of adolescents attending high schools, secondary schools and universities throughout Poland. Questionnaires were completed by 14,511 subjects (10,083 school pupils and 4,428 students). Few persons from each group admitted using DDs; 453 school pupils (4.49%) vs. 81 students (1.83%). More males (4.74%) took DDs than females (2.77%). The tendency to take DDs in the company of friends was high in both DD-taking groups (>80%). DDs were consumed mostly in open spaces (34.15%), discos/pubs (21.13%) and boarding school/friend's house (20.57). Most frequently, DDs came from shops (57.68%), friends (31.46%) or dealers (10.11%). Ensuing symptoms included; happy/euphoric mood (58.80%), talkativeness (42.51%) and hallucinations (22.85%). Over 74% of DD-takers in both groups experienced adverse reactions, and those requiring help sought it from: friends/colleagues (6.74%), doctors (5.06%), and hospitals (4.87%), but most rarely from parents/guardians (2.62%). Urgent action is being taken, especially in youth education, to prevent DDs becoming the serious menace seen with conventional drugs.

    2017-04-01

    Dynamics of runaway electrons in magnetic fields are governed by the competition of three dominant physics: parallel electric field acceleration, Coulomb collision, and synchrotron radiation. Examination of the energy and pitch-angle flows reveals that the presence of local vortex structure and global circulation is crucial to the saturation of primary runaway electrons. Models for the vortex structure, which has an O-point to X-point connection, and the bump of runaway electron distribution in energy space have been developed and compared against the simulation data. Identification of these velocity-space structures opens a new venue to re-examine the conventional understanding of runaway electron dynamics in magnetic fields.

    2014-01-01

    In this letter we investigate factors that influence the effective critical electric field for runaway electron generation in plasmas. We present numerical solutions of the kinetic equation, and discuss the implications for the threshold electric field. We show that the effective electric field necessary for significant runaway formation often is higher than previously calculated due to both (1) extremely strong dependence of primary generation on temperature, and (2) synchrotron radiation losses. We also address the effective critical field in the context of a transition from runaway growth to decay. We find agreement with recent experiments, but show that the observation of an elevated effective critical field can mainly be attributed to changes in the momentum-space distribution of runaways, and only to a lesser extent to a de facto change in the critical field.

  6. Mitigating Thermal Runaway Risk in Lithium Ion Batteries

    2014-01-01

    The JSC/NESC team has successfully demonstrated Thermal Runaway (TR) risk reduction in a lithium ion battery for human space flight by developing and implementing verifiable design features which interrupt energy transfer between adjacent electrochemical cells. Conventional lithium ion (li-Ion) batteries can fail catastrophically as a result of a single cell going into thermal runaway. Thermal runaway results when an internal component fails to separate electrode materials leading to localized heating and complete combustion of the lithium ion cell. Previously, the greatest control to minimize the probability of cell failure was individual cell screening. Combining thermal runaway propagation mitigation design features with a comprehensive screening program reduces both the probability, and the severity, of a single cell failure.

    1989-11-01

    The results of laboratory catalyst tests, conducted in recycle reactors under fixed conditions of feed rate and composition and otherwise at average production conditions, permit the evaluation of catalyst performance for production reactors. These tests are performed in short steady-state runs at stepwise increasing temperatures until a specified product concentration is reached. From these results, in addition to performance evaluation, the thermal stability criteria of the reaction can also be calculated. This information is needed to maximize production within the thermal runaway limit. Since the thermal runaway limit, estimated from the catalyst test, does not contain assumptions on kinetics, the experimentally evaluated runaway limit can be used as a benchmark to help discriminate between kinetic models that were developed from other data sets. The evaluation of the performance as well as the thermal runaway limit is shown on actual experimental measurements made for the production of ethylene oxide by oxidation of ethylene.

  10. Empirical Quantification of the Runaway Greenhouse Limit on Earth

    Goldblatt, C.; Dewey, M. C.

    2015-12-01

    There have been many modeling studies of the runaway greenhouse effect and the conditions required to produce one on an Earth-like planet, however these models have not been verified with empirical evidence. It has been suggested that the Earth's tropics may be near a state of localized runaway greenhouse, meaning the surface temperature and atmospheric composition in those areas could cause runaway greenhouse, were it not for the tempering effects of meridional heat transport and circulation (Pierrehumbert, 1995). Using the assumption that some areas of the Earth's tropics may be under these conditions, this study uses measurements of the atmospheric properties, surface properties, and radiation budgets of these areas to quantify a radiation limit for runaway greenhouse on Earth, by analyzing the dependence of outgoing longwave radiation (OLR) at the top of the atmosphere on surface temperature and total column water vapour. An upper limit on OLR for clear-sky conditions was found between 289.8 W/m2 and 292.2 W/m2, which occurred at surface temperatures near 300K. For surface temperatures above this threshold, total column water vapour increased, but OLR initially decreased and then remained relatively constant, between 273.6 W/m2 and 279.7 W/m2. These limits are in good agreement with recent modeling results (Goldblatt et al., 2013), supporting the idea that some of the Earth's tropics may be in localized runaway greenhouse, and that radiation limits for runaway greenhouse on Earth can be empirically derived.

    The suppression of runaways following disruptions is key for the safe operation of ITER. The massive gas injection (MGI) has been developed to mitigate heat loads, electromagnetic forces and runaway electrons (REs) during disruptions. However, MGI may not completely prevent the generation of REs during disruptions on ITER. Resonant magnetic perturbation (RMP) has been applied to suppress runaway generation during disruptions on several machines. It was found that strong RMP results in the enhancement of runaway production instead of runaway suppression on J-TEXT. The runaway current was about 50% pre-disruption plasma current in argon induced reference disruptions. With moderate RMP, the runway current decreased to below 30% pre-disruption plasma current. The runaway current plateaus reach 80% of the pre-disruptive current when strong RMP was applied. Strong RMP may induce large size magnetic islands that could confine more runaway seed during disruptions. This has important implications for runaway suppression on large machines.

  12. Phase-space Dynamics of Runaway Electrons In Tokamaks

    2010-08-31

    The phase-space dynamics of runaway electrons is studied, including the influence of loop voltage, radiation damping, and collisions. A theoretical model and a numerical algorithm for the runaway dynamics in phase space are developed. Instead of standard integrators, such as the Runge-Kutta method, a variational symplectic integrator is applied to simulate the long-term dynamics of a runaway electron. The variational symplectic integrator is able to globally bound the numerical error for arbitrary number of time-steps, and thus accurately track the runaway trajectory in phase space. Simulation results show that the circulating orbits of runaway electrons drift outward toward the wall, which is consistent with experimental observations. The physics of the outward drift is analyzed. It is found that the outward drift is caused by the imbalance between the increase of mechanical angular momentum and the input of toroidal angular momentum due to the parallel acceleration. An analytical expression of the outward drift velocity is derived. The knowledge of trajectory of runaway electrons in configuration space sheds light on how the electrons hit the first wall, and thus provides clues for possible remedies.

  13. Simulation of abuse tolerance of lithium-ion battery packs

    Science.gov (United States)

    Spotnitz, Robert M.; Weaver, James; Yeduvaka, Gowri; Doughty, D. H.; Roth, E. P.

    A simple approach for using accelerating rate calorimetry data to simulate the thermal abuse resistance of battery packs is described. The thermal abuse tolerance of battery packs is estimated based on the exothermic behavior of a single cell and an energy balance than accounts for radiative, conductive, and convective heat transfer modes of the pack. For the specific example of a notebook computer pack containing eight 18650-size cells, the effects of cell position, heat of reaction, and heat-transfer coefficient are explored. Thermal runaway of the pack is more likely to be induced by thermal runaway of a single cell when that cell is in good contact with other cells and is close to the pack wall.

    Introduction One of the most effective strategies in the prevention of addiction is increasing awareness among young people, towards the tendency for taking drugs their physical, mental and social side effects. Storytelling is effective for increasing characteristics of happiness and resilience. This study uses storytelling, a common and popular method to increase awareness among adolescents. Aim To examine the effect of storytelling-based education on the prevention of drug abuse, based on a readiness to addiction index. Materials and Methods This quasi-experimental study was conducted on 136 high school students (grade one), selected by a cluster sampling procedure from May 2014 to February 2015 in Zabol, Iran. The instrument for gathering data was a readiness to addiction questionnaire. This questionnaire included 41 items for which the scoring of each item followed the Likerts format. The data gathered was analysed using SPSS version 21 with descriptive statistics and inferential statistics. Results The results revealed that the mean of the readiness to addiction index in the case group fell from 75.66±19.99 to 69.57±21.83 (paired t-test; p =0.02); in the control group the same index changed from 103.01±21.88 to 93.98±27.70 (paired t-test, p = 0.775). That is, the index decreased for both groups, but the reduction was statistically significant only for the case group (p =0.02). Conclusion This suggests that the narrative method is effective in reducing adolescents readiness to addiction. Storytelling is an effective way to raise awareness among young people about addiction and its detrimental impacts on health. Therefore, such a technique can be taken into consideration in teaching principles of prevention. PMID:28050403

    This article presents the results of a study conducted with 243 Native American students who were part of a multi-ethnic sample of adolescents attending middle school in a large urban center in the Southwest region of the United States. Native adolescents who felt a stronger sense of belonging in their school were found to report a lower lifetime use of alcohol and cigarettes, lower cigarette and marijuana use in the previous month, lower frequency of current use of these substances, fewer substances ever used, and a later age of initiation into drug use than other Native students. Research implications are discussed in relationship to school environment, culturally-grounded prevention curricula, and school social work practice.

    The article discusses the resilience concept from a critical review. It prioritizes texts produced by organizations with leading roles in the field of child and adolescent health (PAHO, Pan-American Health Organization; ASBRA, the Brazilian Association for Adolescence). The main definitions of resilience are discussed, along with a debate on the contributions and limitations of the current literature. Furthermore, the conceptual and operative possibilities of resilience when confronted with child abuse are discussed, specifically using intra-familial sexual abuse as an example. The authors conclude that the concept of resilience presents polarization around certain axes: "adaptation/overcoming process", "innate/acquired" "permanent/circumstantial". However, they all point to a common ground: the singularity and delicacy of micro-social health-promoting relationships.

  20. Verification of runaway migration in a massive disk

    Energy Technology Data Exchange (ETDEWEB)

    Li, Shengtai [Los Alamos National Laboratory

    2009-01-01

    Runaway migration of a proto-planet was first proposed and observed by Masset and Papaloizou (2003). The semi-major axis of the proto-planet varies by 50% over just a few tens of orbits when runaway migration happens. More recent work by D'Angelo et al. (2005) solved the same problem with locally refined grid and found that the migration rate is sharply reduced and no runaway occurs when the grid cells surrounding the planet are refined enough. To verify these two seemly contradictory results, we independently perform high-resolution simulations, solving the same problem as Masset and Papaloizou (2003), with and without self-gravity. We find that the migration rate is highly dependent on the softening used in the gravitational force between thd disk and planet. When a small softening is used in a 2D massive disk, the mass of the circumplanetary disk (CPD) increases with time with enough resolution in the CPD region. It acts as the mass is continually accreted to the CPD, which cannot be settled down until after thousands of orbits. If the planet is held on a fixed orbit long enough, the mass of CPD will become so large that the condition for the runaway migration derived in Masset (2008) will not be satisfied, and hence the runaway migration will not be triggered. However, when a large softening is used, the mass of the CPD will begin to decrease after the initial increase stage. Our numerical results with and without disk-gravity confirm that the runaway migration indeed exists when the mass deficit is larger than the total mass of the planet and CPD. Our simulations results also show that the torque from the co-orbital region, in particular the planet's Hill sphere, is the main contributor to the runaway migration, and the CPD which is lagged behind by the planet becomes so asymmetric that it accelerates the migration.

    The injection of C60/C nanoparticle plasma jet (NPPJ) into tokamak plasma during a major disruption has the potential to probe the runaway electrons (REs) during different phases of their dynamics and diagnose them through spectroscopy of C ions visible/UV lines. A C60/C NPPJ of ~75 mg, high-density (>1023 m-3), hyper-velocity (>4 km/s), and uniquely fast response-to-delivery time (~1 ms) has been demonstrated on a test bed. It can rapidly and deeply deliver enough mass to increase electron density to ~2.4 × 1021 m-3, ~60 times larger than typical DIII-D pre-disruption value. We will present the results of our investigations on: 1) C60 fragmentation and gradual release of C atoms along C60 NPPJ penetration path through the RE carrying residual cold plasma, 2) estimation of photon emissivity coefficient for the lines of the C ions, and 3) simulation of C60/C PJ penetration to the RE beam location in equivalent conditions to the characteristic ~1 T B-field of DIII-D. The capabilities of this injection technique provide a unique possibility in understanding and controlling the RE beam, which is a critical problem for ITER.

    In the cores of young dense star clusters repeated stellar collisions involving the same object can occur, which has been suggested to lead to the formation of an intermediate-mass black hole. In order to verify this scenario we compute the detailed evolution of the merger remnant of three sequences. We follow the evolution until the onset of carbon burning and estimate the final remnant mass to determine the ultimate fate of a runaway merger sequence. We use a detailed stellar evolution code to follow the evolution of the collision product. At each collision, we mix the two colliding stars, taking account of mass loss during the collision. During the stellar evolution we apply mass loss rates from the literature, as appropriate for the evolutionary stage of the merger remnant. We compute models for high ($Z=0.02$) and low ($Z=0.001$) metallicity to quantify metallicity effects. We find that the merger remnant becomes a Wolf-Rayet star before the end of core hydrogen burning. Mass loss from stellar winds domi...

    This study was designed to empirically assess the potential of microcomputer-based intervention with black adolescents from economically disadvantaged backgrounds. Subjects were 26, 11 through 14-year-old black females and males recruited from three boroughs in New York City. A sample task was administered via microcomputer system followed by a postintervention measurement battery. Observational measures were also employed to assess interactional variables. Subjects' attitudes toward educational content in general, and toward drug and alcohol information delivery in particular, appeared to be a significant intervening variable that could alter the overall efficacy of computer-delivered interventions. Both observational and postintervention measures indicated an overall positive subject response to computer-administered instruction. In contrast, however, respondents indicated a negative response to microcomputer delivery of drug and alcohol related materials. Results of the experiment are discussed along with rationales and future research directions.

    Runaway currents following disruptions have an important effect on the first wall in current tokamaks and will be more severe in next generation tokamaks. The behavior of runaway currents in massive gas injection (MGI) induced disruptions have been investigated in the J-TEXT tokamak. The cold front induced by the gas jet penetrates helically along field lines, preferentially toward the high field side and stops at a location near the q  =  2 surface before the disruption. When the cold front reaches the q  =  2 surface it initiates magnetohydrodynamic activities and results in disruption. It is found that the MGI of He or Ne results in runaway free shutdown in a large range of gas injections. Mixture injection of He and Ar (90% He and 10%Ar) consistently results in runaway free shutdown. A moderate amount of Ar injection could produce significant runaway current. The maximum runaway energy in the runaway plateau is estimated using a simplified model which neglects the drag forces and other energy loss mechanisms. The maximum runaway energy increases with decreasing runaway current. Imaging of the runaway beam using a soft x-ray array during the runaway current plateau indicates that the runaway beam is located in the center of the plasma. Resonant magnetic perturbation (RMP) is applied to reduce the runaway current successfully during the disruption phase in a small scale tokamak, J-TEXT. When the runaway current builds up, the application of RMP cannot decouple the runaway beam due to the lower sensitivity of the energetic runaway electrons to the magnetic perturbation.

    We have used the Hubble Space Telescope to measure the motion in the sky and compute the galactocentric orbit of the black hole X-ray binary GRO J1655-40. The system moves with a runaway space velocity of $112\\pm 18$ km s$^{-1}$ in a highly eccentric ($e = 0.34\\pm 0.05$) orbit. The black hole was formed in the disk at a distance greater than 3 kpc from the Galactic centre and must have been shot to such an eccentric orbit by the explosion of the progenitor star. The runaway linear momentum and kinetic energy of this black hole binary are comparable to those of solitary neutron stars and millisecond pulsars. GRO J1655-40 is the first black hole for which there is evidence for a runaway motion imparted by a natal kick in a supernova explosion.

  12. Magnetic field modification to the relativistic runaway electron avalanche length

    2016-11-01

    This paper explores the impact of the geomagnetic field on the relativistic runaway electron avalanche length, λe-. Coleman and Dwyer (2006) developed an analytical fit to Monte Carlo simulations using the Runaway Electron Avalanche Model. In this work, we repeat this process but with the addition of the geomagnetic field in the range of [100,900]/n μT, where n is the ratio of the density of air at altitude to the sea level density. As the ambient electric field approaches the runaway threshold field (Eth≈284 kV/m sea level equivalent), it is shown that the magnetic field has an impact on the orientation of the resulting electron beam. The runaway electrons initially follow the vertically oriented electric field but then are deflected in the v × B direction, and as such, the electrons experience more dynamic friction due to the increase in path length. This will be shown to result in a difference in the avalanche length from the case where B = 0. It will also be shown that the average energy of the runaway electrons will decrease while the required electric field to produce runaway electrons increases. This study is also important in understanding the physics of terrestrial gamma ray flashes (TGFs). Not only will this work impact relativistic feedback rates determined from simulations, it may also be useful in studying spectroscopy of TGFs observed from balloon and aircraft measurements. These models may also be used in determining beaming properties of TGFs originating in the tropical regions seen from orbiting spacecraft.

    This task was developed in the wake of the Boeing 787 Dreamliner lithium-ion battery TR incidents of January 2013 and January 2014. The Electrical Power Technical Discipline Team supported the Dreamliner investigations and has followed up by applying lessons learned to conduct an introspective evaluation of NASA's risk of similar incidents in its own lithium-ion battery deployments. This activity has demonstrated that historically NASA, like Boeing and others in the aerospace industry, has emphasized the prevention of TR in a single cell within the battery (e.g., cell screening) but has not considered TR severity-reducing measures in the event of a single-cell TR event. center dotIn the recent update of the battery safety standard (JSC 20793) to address this paradigm shift, the NASA community included requirements for assessing TR severity and identifying simple, low-cost severity reduction measures. This task will serve as a pathfinder for meeting those requirements and will specifically look at a number of different lithium-ion batteries currently in the design pipeline within the ISS Program batteries that, should they fail in a Dreamliner-like incident, could result in catastrophic consequences. This test is an abuse test to understand the heat transfer properties of the cell and ORU in thermal runaway, with radiant barriers in place in a flight like test in on orbit conditions. This includes studying the heat flow and distribution in the ORU. This data will be used to validate the thermal runaway analysis. This test does not cover the ambient pressure case. center dotThere is no pass/ fail criteria for this test.

    The topology of a magnetic field and transport properties of runaway electrons can be changed by a resonant magnetic perturbation field. The J-TEXT magnetic topology can be effectively altered via static resonant magnetic perturbation (SRMP) and dynamic resonant magnetic perturbation (DRMP). This paper studies the effect of resonant magnetic perturbation (RMP) on the confinement of runaway electrons via simulating their drift orbits in the magnetic perturbation field and calculating the orbit losses for different runaway initial energies and different runaway electrons, initial locations. The model adopted is based on Hamiltonian guiding center equations for runaway electrons, and the J-TEXT magnetic turbulences and RMP are taken into account. The simulation indicates that the loss rate of runaway electrons is sensitive to the radial position of electrons. The loss of energetic runaway beam is dominated by the shrinkage of the confinement region. Outside the shrinkage region of the runaway electrons are lost rapidly. Inside the shrinkage region the runaway beam is confined very well and is less sensitive to the magnetic perturbation. The experimental result on the response of runaway transport to the application RMP indicates that the loss of runaway electrons is dominated by the shrinkage of the confinement region, other than the external magnetic perturbation.

    CERN Document Server

    Kobayashi, Hiroshi; Okuzumi, Satoshi

    2015-01-01

    When planetesimals grow via collisions in a turbulent disk, stirring through density fluctuation caused by turbulence effectively increases the relative velocities between planetesimals, which suppresses the onset of runaway growth. We investigate the onset of runaway growth in a turbulent disk through simulations that calculate the mass and velocity evolution of planetesimals. When planetesimals are small, the average relative velocity between planetesimals, $v_{\\rm r}$, is much greater than their surface escape velocity, $v_{\\rm esc}$, so that runaway growth does not occur. As planetesimals become large via collisional growth, $v_{\\rm r}$ approaches $v_{\\rm esc}$. When $v_{\\rm r} \\approx 1.5 v_{\\rm esc}$, runaway growth of the planetesimals occurs. During the oligarchic growth subsequent to runaway growth, a small number of planetary embryos produced via runaway growth become massive through collisions with planetesimals with radii of that at the onset of runaway growth, $r_{\\rm p,run}$. We analytically der...

    Production of runaway electrons during disruptions has been observed in the HT-7 Tokamak. The runaway current plateaus, which can carry part of the pre-disruptive current, are observed in lower-hybrid current drive (LHCD) limiter discharges. It is found that the runaway current can mitigate the disruptions effectively. We can use gas puffing to increase the line-averaged density to restrain the runaway electrons and rebuild the plasmas after the disruptions. Detailed observations are presented on the runaway electrons generated following disruptions in the HT-7 tokamak discharges. The results indicate that the magnetic oscillations play a significant role in the loss of runaway electrons in disruptions. There are two important preconditions to rebuild plasmas by runaway electrons after the disruptions. One of them are weak magnetic oscillations; another one are LHWs (lower-hybrid waves) (copyright 2011 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    2015-01-01

    Based on the analysis of data from the numerous dedicated experiments on plasma disruptions in the TEXTOR tokamak mechanisms of the formation of runaway electron beams and their losses are proposed. The plasma disruption is caused by strong stochastic magnetic field formed due to nonlinearly excited low-mode number MHD modes. It is hypothesized that the runaway electron beam is formed in the central plasma region confined inside the intact magnetic surface located between $q=1$ and the closest low--order rational [$q=4/3$ or $q=3/2$] magnetic surfaces. The thermal quench time caused by the fast electron transport in a stochastic magnetic field is calculated using the collisional transport model. The current decay stage is due to the ambipolar particle transport in a stochastic magnetic field. The runaway electron beam in the confined plasma region is formed due to their acceleration the inductive toroidal electric field. The runaway electron beam current is modeled as a sum of toroidally symmetric part and a ...

  2. How close is Earth to a runaway greenhouse?

    Ramirez, Ramses M; Lindner, Valerie; Kasting, James F

    2013-01-01

    Recent calculations suggest that the inner edge of the habitable zone around the Sun could be as far out as 0.99 astronomical units (AU)- much closer to the orbit of Earth than had been thought. This reopens the question of whether future increases in atmospheric CO2 might trigger a runaway or moist greenhouse. A runaway greenhouse implies complete ocean vaporization; a moist greenhouse implies that the stratosphere becomes wet, leading to ocean loss via hydrogen escape to space. Previous studies (Kasting and Ackerman, 1986) had indicated that neither a moist nor a runaway greenhouse could be triggered by CO2 increases of any magnitude. Here, we revisit this question with a 1-D climate model that includes updated absorption coefficients for CO2 and H2O, along with an improved parameterization of tropospheric relative humidity. We find that a runaway greenhouse is still precluded. However, a moist greenhouse could conceivably be triggered by an 11-fold increase in atmospheric CO2, and humans could be subject t...

    Methylphenidate is a stimulant used in the treatment of attention deficit hyperactivity disorder in children and is subject to abuse. This study describes the patterns of methylphenidate abuse and drug identification (ID) calls received by several poison control centers in Texas. Cases were calls involving methylphenidate received by Texas poison control centers during 1998-2004. Drug ID and drug abuse calls were assessed by call year and geographic location. Drug abuse calls were then compared to all other human exposure (nonabuse) calls with respect to various factors. Of 6798 calls received involving methylphenidate, 35% were drug IDs and 56% human exposures. Of the human exposures, 9% involved abuse. The number of drug ID calls and drug abuse calls received per year both declined during the first part of 7-yr period but then increased. Male patients accounted for approximately 60% of both drug abuse and nonabuse calls. Adolescent patients comprised 55% of drug abuse calls and children less than 13 yr old comprised 62% of nonabuse calls. Although the majority of both types of human exposures occurred at the patient's own residence, drug abuse calls were more likely than non-abuse calls to involve exposures at school (15% vs. 6%) and public areas (3% vs. 0.4%). While drug abuse calls were less likely than nonabuse calls to present with no clinical effects (29% vs. 52%), they were more likely to show more serious medical outcomes. Methylphenidate abusers are more likely to be adolescents. Methylphenidate abuse as compared to other exposures is more likely to occur outside of the person's home and to involve more serious medical outcomes.

    The purpose of this study was to investigate the phenomenon of loneliness in delinquent adolescents with regard to types of delinquency offenses committed, demographic characteristics, and personality characteristics in the areas of interpersonal needs for inclusion, control, and affection. The types of delinquency offenses were categorized as burglary, runaway, drugs, assault, and incorrigible. The demographic variables examined were age, sex, race, family rank or birth order, family structure in terms of parental presence, family income level, religion, and geographic locale. A sample of 98 adolescents was obtained from juvenile detention facilities in three metropolitan areas in the United States. Subjects ranged in age from 12 to 18. Subjects were asked to complete the Loneliness Questionnaire as a self-reported measure of loneliness. Subjects also provided information about themselves relative to demographic characteristics and completed the FIRO-B Questionnaire, which measured interpersonal needs for inclusion, control, and affection. The results revealed no significant differences with regard to any of the demographic variables when the effect of each was considered alone. However, there was a significant effect on loneliness by income when considered jointly with other demographic variables. Adolescents from the middle income group expressed more loneliness than those from the upper and lower income groups. No significant differences were observed with regard to personality characteristics related to interpersonal needs for inclusion and affection, but delinquent adolescents with medium to high needs for control indicated significantly more feelings of loneliness than delinquent adolescents with low needs for control.

    There is now conclusive evidence of the major and long-lasting negative effects of physical and sexual abuse on children. Within Africa, studies consistently report high rates of child abuse, with prevalence as high as 64%. However, to date, there has been no review of factors associated with physical and sexual child abuse and polyvictimization in Africa. This review identified 23 quantitative studies, all of which showed high levels of child abuse in varying samples of children and adults. Although studies were very heterogeneous, a range of correlates of abuse at different levels of the Model of Ecologic Development were identified. These included community-level factors (exposure to bullying, sexual violence, and rural/urban location), household-level factors (poverty, household violence, and non-nuclear family), caregiver-level factors (caregiver illness in particular AIDS and mental health problems, caregiver changes, family functioning, parenting, caregiver-child relationship, and substance abuse), and child-level factors (age, disability, physical health, behavior, and gender). These findings identify key associated factors that are potential foci of child abuse prevention interventions. In addition, there is a clear need for further rigorous longitudinal research into predictive factors and culturally relevant interventions.

    Thermal runaway is a well-known safety concern in Li-ion cells. Methods to predict and prevent thermal runaway are critically needed for enhanced safety and performance. While much work has been done on understanding the kinetics of various heat generation processes during thermal runaway, relatively lesser work exists on understanding how heat removal from the cell influences thermal runaway. Through a unified analysis of heat generation and heat removal, this paper derives and experimentally validates a non-dimensional parameter whose value governs whether or not thermal runaway will occur in a Li-ion cell. This parameter is named the Thermal Runaway Number (TRN), and comprises contributions from thermal transport within and outside the cell, as well as the temperature dependence of heat generation rate. Experimental data using a 26650 thermal test cell are in good agreement with the model, and demonstrate the dependence of thermal runaway on various thermal transport and heat generation parameters. This parameter is used to predict the thermal design space in which the cell will or will not experience thermal runaway. By combining all thermal processes contributing to thermal runaway in a single parameter, this work contributes towards a unified understanding of thermal runaway, and provides the fundamental basis for design tools for safe, high-performance Li-ion batteries.

    This study inquires into neurobiological response to stress and its clinical correlates among adolescents with post-traumatic stress disorder (PTSD). Structural magnetic resonance imaging (MRI) measures of cerebral anatomy were carried out on 23 female adolescents with PTSD related to severe childhood sexual abuse and 21 matched healthy controls. Clinician Administered PTSD Scale for Children and Adolescents, Adolescent Dissociative Experiences Scale, Childhood Trauma Questionnaire, Schedule for Affective Disorders and Schizophrenia for School Age Children, Beck Depression Scale, and a set of neuro-cognitive tests were administered to all participants. Compared to controls, PTSD group bilaterally had smaller amygdala, hippocampus, anterior cingulate, and thinner prefrontal cortex but normal thalamus. Further analyses within the PTSD group suggested an association between symptoms of PTSD and sizes of right brain structures including smaller amygdala but larger hippocampus and anterior cingulate. Thinner right prefrontal cortex and larger right thalamus seemed to be related to denial and response prevention, respectively. Being related to both hemispheres, dissociative amnesia was negatively associated with proportion of the right amygdala to right thalamus and to both left and right prefrontal cortex. Suggesting a neuro-protective effect against traumatic stress at least through adolescence, depersonalization-derealization and identity alteration were correlated with thicker left prefrontal cortex. Unlike the lateralization within PTSD group, correlations between regions of interest were rather symmetrical in controls. The graded response to stress seemed to be aimed at mental protection by lateralization of brain functions and possibly diminished connection between two hemispheres. A Tri-Modal Reaction (T-MR) Model of protection is proposed.

    We used a longitudinal twin design to examine selection effects of personality traits at age 11 on high-risk environmental contexts at age 14 and the extent to which these contexts mediated risk for substance abuse at age 17. Socialization at age 11 (willingness to follow rules and endorse conventional values) predicted exposure to contextual risk at age 14. Contextual risk partially mediated the effect of socialization on substance abuse, though socialization also had a direct effect. In con...

    When the energy of confined runaway electrons approaches several tens of MeV, the runaway electrons can emit synchrotron radiation in the range of infrared wavelength. An infrared camera working in the wavelength of 3-5 μm has been developed to study the runaway electrons in the Joint Texas Experimental Tokamak (J-TEXT). The camera is located in the equatorial plane looking tangentially into the direction of electron approach. The runaway electron beam inside the plasma has been observed at the flattop phase. With a fast acquisition of the camera, the behavior of runaway electron beam has been observed directly during the runaway current plateau following the massive gas injection triggered disruptions.

  17. Runaway Merging of Black Holes Analytical Constraint on the Timescale

    Following the discovery of a black hole (BH) with a mass of 10^3-10^6 M(sun) in a starburst galaxy M82, we study formation of such a BH via successive merging of stellar-mass BHs within a star cluster. The merging has a runaway characteristic. This is because massive BHs sink into the cluster core and have a high number density, and because the merging probability is higher for more massive BHs. We use the Smoluchowski equation to study analytically the evolution of the BH mass distribution. Under favorable conditions, which are expected for some star clusters in starburst galaxies, the timescale of the runaway merging is at most of order 10^7 yr. This is short enough to account for the presence of a BH heavier than 10^3 M(sun) in an ongoing starburst region.

    The effect of runaway electrons has been studied in this work. There were derived the conditions runaway electrons, the influence of electric field on the electron velocity distribution is considered for nonideal classical plasma models. The dependence of friction force on electrons on their velocities,electron-ion collision frequency as a function of the coupling parameter and the strength of critical electric field on particle density and temperature are determined. The results are compared with the asymptotic theory. It has been shown that for the definite density and temperature ranges the difference between critical electric field values is essential for various plasma models.

  20. ICPP: Scale size of of magnetic turbulence as probed with 30 MeV runaway electrons

    Jaspers, Roger

    2000-10-01

    This paper reviews results concerning generation, confinement and transport of runaway electrons in the energy range 20-30 MeV in the TEXTOR tokamak. For future fusion reactors, it is of major importance to know the processes of runaway generation and runaway loss after disruptions, because of the potential damage to first wall components. Second, since the runaway electrons are effectively collisionless, their confinement is determined by the magnetic field turbulence. In this way the runaway transport provides a unique opportunity to probe turbulence in the core of a thermonuclear plasma. Runaway electrons above 20 MeV emit synchrotron radiation in the (near) infrared, which can easily be detected by thermographic cameras. This technique is developed and exploited at the TEXTOR-94 tokamak and has resulted in some spectacular results. These include: the experimental evidence of the secondary (`knock-on') runaway generation; the discovery of the runaway snake; the observation of disruption generated runaways; the probing of magnetic turbulence in the core of the plasma in Ohmic and additionally heated plasmas. The paper reviews these results with special emphasis on the subject of probing magnetic turbulence in the core of the plasma. Measurements in the TEXTOR-94 tokamak show that after switching on Neutral Beam Injection, the runaway population decays. The decay only starts with a significant delay, which decreases with increasing NBI heating power. This delay provides direct evidence of the energy dependence of runaway confinement, which is expected if magnetic modes govern the loss of runaway electrons. These observations allow to estimate the mode width δ of the magnetic perturbations:δ smaller than 0.5 cm in Ohmic discharges, increasing to δ=3D 4.4 cm for 0.6 MW NBI power.
