    Research suggests family disturbance is highly correlated to adolescents running away from home. However, given methodological challenges, few studies assess parent report of the family situation and instead, rely primarily on adolescent self-report. This article reports the findings of parents' and runaway adolescents' reports on several behavioral dimensions. Substance-using runaway adolescents completed measures about their family environment and adolescent problem behaviors. Of 119 adolescents, 49 of their parents also completed measures at intake. Adolescents perceived a more negative family environment than did their parents, and parents rated their youth as having more externalizing problems than did the youth themselves. Findings are consonant with prior research showing a relationship between parental distress and child problems. Contrary to prior findings, this sample of parents did not report significant alcohol use, and there was no relationship between their use and their child's use. Implications for future research and family therapy are discussed. PMID:18776946

The instrument used was Young’s schema questionnaire. Results. The results of the discriminate analysis showed that after the stepwise analysis, 4 variables were remained which from the 1 st to the 4 th steps are subsequently: emotional deprivation, vulnerability to dan - ger, defectiveness/shame and dependence/incompetence. The results of the function group categorization analysis showed that all adolescents of the normal group were predicted correctly (100%, however, the discriminate function had placed 96.7% of the runaway group in the right place and 3.3% were wrongly categorized. In general, the discriminate function categorized 98.6% of all cases correctly and this claims a high predictive power and a significant validity for this model. Discussion and Conclusion. The results were compiled based on theoretical foundations and the role of the schemas in adolescent girls’ running away was discussed

    Full Text Available Objective:Substance abuse in adolescents may also be a marker to other harmful life styles. This study aims to find out the prevalence, pattern and sociodemographic risk factors of substance abuse in male adolescents. Methods:This study examined 390 male school children aged 10-19 years in the rural and urban areas of district Aligarh, Uttar Pradesh, India. Data was analyzed by SPSS -10. Findings:Substance abuse was prevalent in 13.3% of adolescents of whom 96.1% were using various forms of tobacco and 3.8% were taking alcohol. While there was statistically significant association between the substance abuse and the age group of adolescents and size of their families, variables such as religion, socioeconomic status, place of residence were not associated with substance use. Most of the students reported initiation of substance use at 14 yrs of age due to peer pressure. Conclusion:Peer educators would be a useful strategy for communication with adolescents to counter peer pressure. The prevention and control measures should be started at primary education level.

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.

    Directory of Open Access Journals (Sweden)

    Girish H Banwari

    2013-01-01

    Full Text Available Traditionally, sexual abuse is under-reported and under-recognized when the victims are boys. A study carried out by the Government of India in 2007 suggests that every second child/adolescent in the country faces some form of sexual abuse and it is nearly equally prevalent in both sexes. The significance of the problem is undermined all the more when the abuse is perpetrated by a peer. Sexual activity between children and adolescents that occurs without consent or as a result of coercion is tantamount to abuse. A majority of the victims do not disclose the occurrence to anyone. This often neglected issue of adolescent male peer sexual abuse in a sexually conservative country like India is highlighted and discussed through this case, which came to light only after the victim developed a venereal disease.

A study carried out by the Government of India in 2007 suggests that every second child/adolescent in the country faces some form of sexual abuse and it is nearly equally prevalent in both sexes. The significance of the problem is undermined all the more when the abuse is perpetrated by a peer. Sexual activity between children and adolescents that occurs without consent or as a result of coercion is ...

    Leclerc, Benoit; Felson, Marcus

    2016-03-01

    Adolescent abuse of younger children has long been recognized, but empirical research on the circumstances of this phenomenon is rare. This article examines how adolescent offenders find and gain access to victims, work out time alone with them, and set up or exploit settings for sexual contact. Prior researchers learned that adult sex offenders use certain routine activities to perform these tasks. The current research inquires whether adolescent offenders are similar. We administered Kaufman's Modus Operandi Questionnaire to a sample of 116 Canadian adolescent males undergoing treatment for a sexual offense against a child. Adolescent offenders follow routines similar to adults but are better able to use games and activities as a prelude to sexual abuse. We discuss how routine legal activities set the stage for activities and should be considered when devising situational prevention strategies. PMID:25060598

    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.

    Four hundred seventy-nine drug abusing adolescent patients enrolled in seven Straight, Inc. Adolescent Drug-Abuse Treatment Programs in five geographic regions across the United States were studied to determine the severity and patterns of cocaine abuse. Of these, 341 admitted to cocaine use and became part of this survey. Cocaine use was categorized as heavy, intermediate, or light. Areas examined were the addictive spectrum, psychosocial dysfunction, and psychiatric symptoms. Intermediate and heavy users of cocaine abused significantly less marijuana and inhalants than light cocaine abusers. Heavy and intermediate users were more likely to use cocaine intravenously and to use crack. They developed tachyphylaxis more frequently, progressed to weekly use in less than 3 months more frequently, and became preoccupied with obtaining and using cocaine significantly more frequently. They used more sedative hypnotics to calm themselves and engaged in more criminal behavior, such as stealing from parents and stores and passing bad checks. They had more arrests for possession of drugs, stole more cars, sold more drugs, and were more likely to trade sexual favors to obtain the drug. Heavy and intermediate users were significantly more psychiatrically disturbed than light users, becoming more suspicious, nervous, aggressive, and demonstrating increased symptoms of fatigue, sleeplessness, decreased appetite, and increasing cocaine dysphoria. All of these symptoms could be mistaken for psychiatric disorders. This study suggests that cocaine is as addictive in adolescents as in adults; possibly more so. It also causes psychosocial dysfunction and psychiatric symptoms. Further research into cocaine addiction among adolescents is indicated. PMID:2582695

    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.

    Abstract Background Studies among adults show an association between abuse and Body Mass Index (BMI) status. When an aberrant BMI status as a consequence of abuse is already prevalent in adolescence, early detection and treatment of abuse might prevent these adolescents from developing serious weight problems and other long-term social, emotional and physical problems in adulthood. Therefore, this study investigated the prevalence of physical, sexual and mental abuse among adolescents and exa...

    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.

    2013-02-01

    The aim of this study was to identify two sub-populations of sex offenders based on the age of the victims and on the age difference between the abuser and the victim (child sexual abusers vs. peer sexual abusers), and to compare the personality characteristics of these two subgroups with those of juvenile non-sex offenders. The group was composed of 67 adolescent offenders aged 13-18 years who were adjudicated for sexual offenses or non-sexual offenses: 20 non-sex offenders (JNSOs), 26 child sexual abusers (CAs), and 21 peer sexual abusers (PAs). The Millon Adolescent Clinical Inventory (MACI) was administered to all participants. The mean scores and clinical cutoffs on the MACI scales were compared across the three samples. Compared with PAs, CAs were more submissive and conforming, and they experienced more anxious feelings. Peer sexual abusers scored higher on the unruly and forceful personality scales, on social insensitivity, and on delinquent predisposition. Peer sexual abusers also reported higher scores on substance-abuse proneness, impulsive propensities, and antisocial functioning than CAs, but their scores were similar to those of JNSOs. Our results show clear similarities between PAs and JNSOs in terms of personality and clinical characteristics, especially with regard to antisocial personality traits. Child sexual abusers did not display the personality characteristics typical of PAs and JNSOs which predisposed them to delinquent activities. These results raise questions as to whether juvenile sex offenders should be treated within the same institutions as non-sex offenders and whether the same treatment programs should be implemented for all types of juvenile sex offenders.

    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.

    This study examined the roles played by parental alcohol abuse and social support, peer substance abuse risk and social support, and substance abuse risk among adolescents in South Korea. Participants were adolescents between the ages of 15 and 22 years (mean, 18), residing in Seoul city and in surrounding Kyung-gi Province. Of 259 participants, 41.3% scored 2 or more on the POSIT scale, which suggested they met the problematic criteria for substance abuse risk. Logistic regression results suggested that the influence of social support on substance abuse risk among adolescents depended on the source of support--parents or peers. These findings need to be considered in the development of intervention programs for adolescents at risk for substance abuse. PMID:19435169

    Parenting behaviors such as monitoring and communications are known correlates of abusive outcomes in adolescent dating relationships. This longitudinal study draws on separate parent (58 % female; 61 % White non-Hispanic, 12 % Black non-Hispanic, 7 % other non-Hispanic, and 20 % Hispanic) and youth (ages 12-18 years; 48 % female) surveys from the nationally representative Survey of Teen Relationships and Intimate Violence. Latent class analyses were applied to investigate whether there are distinguishable parenting profiles based on six measures of parent-youth relationship and interactions, with youth's attitudes about abusive dating behavior and both perpetration and victimization examined in a follow-up survey as distal outcomes (n = 1117 parent-youth dyads). A three-class model-a "Positive Parenting" class, a "Strict/Harsh Parenting" class, and a "Disengaged/Harsh Parenting" class-was selected to best represent the data. The selected latent class model was conditioned on parents' (anger trait, relationship quality, attitudes about domestic violence) and youth's (prior victimization and perpetration) covariates, controlling for parent's gender, race/ethnicity, income, marital status, and youth's age and gender. Youth in the "Positive Parenting" class were significantly less likely 1 year later to be tolerant of violence against boyfriends under any conditions as well as less likely to perpetrate adolescent relationship abuse or to be a victim of adolescent relationship abuse. Parents' anger and relationship quality and youth's prior perpetration of adolescent relationship abuse as well as gender, age, and race/ethnicity predicted class membership, informing universal prevention program and message design, as well as indicated efforts to target communications and services for parents as well as for youth.

    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.

    2010-10-01

    The causes of adolescent substance use are multifactorial, but the media can play a key role. Tobacco and alcohol represent the 2 most significant drug threats to adolescents. More than $25 billion per year is spent on advertising for tobacco, alcohol, and prescription drugs, and such advertising has been shown to be effective. Digital media are increasingly being used to advertise drugs. In addition, exposure to PG-13- and R-rated movies at an early age may be a major factor in the onset of adolescent tobacco and alcohol use. The American Academy of Pediatrics recommends a ban on all tobacco advertising in all media, limitations on alcohol advertising, avoiding exposure of young children to substance-related (tobacco, alcohol, prescription drugs, illegal drugs) content on television and in PG-13- and R-rated movies, incorporating the topic of advertising and media into all substance abuse-prevention programs, and implementing media education programs in the classroom.

    2014-01-01

    Full Text Available Herpes simplex virus infection is mostly spread and occurs more commonly among substance abusing adolescents as compared to the nonsubstance abusing. In this paper, a mathematical model for the spread of HSV-2 within a community with substance abusing adolescents is developed and analysed. The impacts of condom use and educational campaigns are examined. The study suggests that condom use is highly effective among adolescents, when we have more of them quitting than becoming substance abusers. Measures such as educational campaigns can be put in place to try and reduce adolescents from becoming substance abusers. Further, we applied optimal control theory to the proposed model. The controls represent condom use and educational campaigns. The objective is based on maximising the susceptible nonsubstance abusing adolescents, while minimising the susceptible substance abusing adolescents, the infectious nonsubstance abusing adolescents, and the infectious substance abusing adolescents. We used Pontrygin’s maximum principle to characterise the optimal levels of the two controls. The resulting optimality system is solved numerically. Overall, the application of the optimal control theory suggests that more effort should be devoted to condom use as compared to educational campaigns.

  6. Brain SPECT perfusion in children and adolescents poly drug abusers

    International Nuclear Information System (INIS)

    Polydrug abuse in children and adolescents is a major social problem. Aim: The aim of this study was to evaluate brain perfusion in polydrug abuser adolescents with brain SPECT imaging (BSI) using 99mTc-HMPAO. Materials and Methods: Sixteen male polydrug abuser patients (11 to 18 years) were submitted to BSI. Forty-eight normal individuals (26 males, 22 females; 18 to 31 years) were used as a control group. Images were performed after an intravenous injection of 99mTc-HMPAO in a dark, quiet room. Images were acquired in a camera-computer system equipped with a fan beam collimator. The images were reconstructed in the transaxial, coronal and sagittal views and submitted to semi-quantitative analysis using the thalami as reference, by placing regions of interest (ROIs) in the cerebral and cerebellar cortices. Patients were also submitted to neuropsychology tests and neurologic examination. Results: Significant hypoperfusion was found in the inferior portion of the frontal lobes (left and right: p<0.0001), temporal lobes (left lateral: p=0.0392; right lateral: p=0.0044; left and right mesial: p<0.0005), right parietal lobe (p=0.025), visual cortex (p=0.0013), pons (p = 0.0002), cerebellar hemispheres (left: p=0.0216; right: p=0.0005) and vermis (p=0.0015). An inverse relationship was observed between the degree of perfusion and the duration of drug abuse in the inferior left frontal lobe (? = -0.55; p=0.0255), superior right frontal lobe (? = -0.51; p=0.043), lateral right temporal lobe (? = -0.58; p=0.0172), mesial left temporal lobe (? -0.52; p=0.0384), left parietal lobe (? = -0.51; p=0.0416), basal ganglia (left: ? = -0.70; p=0.0022; right: ? = -0.65; p=0.0056) and cingulate gyrus (? = -0.66; p=0.0054). A significant correlation was observed between the perfusion of the temporal lobes with the Bender-Koppits test (left and right lateral: p=0.0559). Significant correlation was also noted between the perfusion of the lateral left temporal lobe (p=0.0559), parietal

    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.

    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. PMID:27068856

    2012-05-01

    As concern grows over the impact that accidental chemical exposures may have on the long term health of individuals, our young people are deliberately exposing themselves to the effect of neurotoxic chemicals with the intent of feeling high. Over time the result of inhaling these chemicals is often the development of symptoms and behavior that may suggest serious physiological damage. Research is being conducted to examine what the exact nature of the damage might be, especially the impact of inhaled lipophilic chemicals on structures in the brain and other parts of the nervous system. Healthcare professionals responsible for assessing adolescents in all settings need to be aware of the prevalence of inhalant abuse, as well as the chemicals, terminology, and potential symptomatology in order to intervene in the behavior and provide diagnosis and treatment as indicated. Some implications for nursing are included. PMID:22471781

    Full Text Available Abstract Background Studies among adults show an association between abuse and Body Mass Index (BMI status. When an aberrant BMI status as a consequence of abuse is already prevalent in adolescence, early detection and treatment of abuse might prevent these adolescents from developing serious weight problems and other long-term social, emotional and physical problems in adulthood. Therefore, this study investigated the prevalence of physical, sexual and mental abuse among adolescents and examined the association of these abuse subtypes with BMI status. Methods In total, data of 51,856 secondary school students aged 13–16 who had completed a questionnaire on health, well-being and lifestyle were used. BMI was classified into four categories, underweight, normal weight, overweight and obesity. Adolescents reported if they had ever been physically, sexually or mentally abused. Crude and adjusted General Estimation Equation (GEE analyses were performed to investigate the association between abuse subtypes and BMI status. Analyses were adjusted for ethnicity and parental communication, and stratified for gender and educational level. Results Eighteen percent of the adolescents reported mental abuse, 7% reported sexual abuse, and 6% reported physical abuse. For underweight, overweight and obese adolescents these percentages were 17%, 25%, and 44%; 7%, 8%, and 16%; and 6%, 8%, 18% respectively. For the entire population, all these subtypes of abuse were associated with being overweight and obese (OR=3.67, 1.79 and 1.50 and all but sexual abuse were associated with underweight (OR=1.21 and 1.12. Stratified analyses showed that physical and sexual abuse were significantly associated with obesity among boys (OR=1.77 and 2.49 and among vocational school students (OR=1.60 and 1.69, and with underweight among girls (OR=1.26 and 0.83.

    Full Text Available Background and Objective: Adolescence is the most critical period of life as regards commencing drug abuse. The social cost and damage caused by drug abuse in adolescence are enormous, necessitating interventional programs to prevent this behavior. The theory of planned behavior (TPB is perhaps the most influential theory for the prediction of social and health behaviors such as drug abuse.Materials and Methods: In this descriptive analytical study, samples were collected from male students in four high schools in different regions of Hamedan. The survey was carried out via random cluster sampling of 650 students. Data were collected using the standard self-report questionnaires and were analyzed using SPSS16, chi-squared test, correlation coefficient, and logistic regression analysis.Results: Among the adolescents participating in this study, 11.1% had the experience of cigarette smoking, 3.4% had the experience of drug abuse, and 12% had the experience of intention to abuse drugs. There was a significant relationship between drug abuse and the following variables: smoking experience (p value =0.001, OR=27.238; having drug user parents (p value =0.001, OR=8.630; having friends who had experienced drug abuse (p value =0.001, OR=11.060; having best friends who had experienced drug abuse (p value = 0.001, OR=11.931; family with drug abuse (p value = 0.001, OR=4.311; and having a sibling who abused drugs (p value=0.001, OR=15.815. According to the logistic regression analysis, attitude, subjective norms, and perceived behavior control were the most influential predictors of intention to abuse drugs.Conclusion: The use of TPB is beneficial in the predicting and planning for high-risk behaviors. TPB can be used for planning and implementing drug abuse prevention programs in adolescents.

  14. Parental substance use disorder and the risk of adolescent drug abuse: an event history analysis.

    A common observation in the research literature is that children of drug-dependent parents are at significantly heightened risk of adolescent drug use, abuse, and dependence. Recent research indicates that several psychological and interpersonal factors may affect the association between parents' psychoactive substance use disorder (PSUD) and drug use risks among adolescents, yet studies have failed to examine explicitly whether these factors moderate the association between PSUD and adolescent substance abuse. This paper explores these potential relationships using longitudinal data from a study that has followed three cohorts of adolescents and their families over a 7-year period. The cohorts are defined by parental diagnoses of PSUD, affective disorders, or no diagnosable disorder. The results indicate that PSUD is positively associated with adolescent drug abuse, yet this association is attenuated by strong family cohesion. Affective disorders among parents are associated with a higher risk of alcohol, but not drug, abuse. The associations are stronger in the presence of lower stress and higher self-esteem. PSUD is also associated more strongly with offspring drug and alcohol abuse when levels of use are lower. Hence, some unobserved mechanism that may involve physiological sensitivities to drugs and alcohol appears to put children of parents with drug problems at particular risk of drug and alcohol abuse. Limitations of the data and analysis are discussed. PMID:12062460

    This study investigated the association between self-perceived oral health and self-reported exposure to different types of child abuse. It was hypothesized that self-perceived oral health is compromised in exposed adolescents. All Grade-9 compulsory school and second-year high-school pupils in Södermanland County, Sweden (n = 7,262) were invited to take part in a population-based survey; 5,940 adolescents responded. Survey items on health and social wellbeing included self-perceived oral health and exposure to abuse. The results showed that poor self-perceived oral health was associated with self-reported experience of physical abuse, intimate partner violence, forced sex, and bullying (adjusted OR = 2.3-14.7). The likelihood of reporting poor oral health increased from an adjusted OR of 2.1 for a single incident of abuse to an adjusted OR of 23.3 for multiple abuses. In conclusion, poor self-perceived oral health and previous exposure to child physical abuse, intimate partner violence, bullying, and forced sex is associated. It is important that dental professionals recognize adolescents with poor subjective oral health and take into consideration child abuse as a possible cause in order to prevent these adolescents from further victimization. These results further strengthen that dental professionals are an important resource in child protection. PMID:24206076

    This article provides an ecological framework for understanding adolescent-initiated parent abuse. We review research on adolescent-initiated parent abuse, identifying sociodemographic characteristics of perpetrators and victims (e.g., gender, age, race/ethnicity, and socioeconomic status [SES]). Bronfenbrenner's [1] ecological systems theory is applied, which examines the risk and protective factors for adolescent-initiated parent abuse within micro- (maltreatment, domestic violence, parenting behavior and disciplinary strategies), meso- (peer influence), exo- (media influence), macro- (gender role socialization), and chronosystem (change in family structure) levels. Findings from our review suggest that older and White children are significantly more likely to abuse their parents. Females are selective in the target of their aggression, while males target family members in general. Mothers are significantly more likely to be abused than fathers. However, researchers also report variations in the association between SES and parent abuse. Domestic violence and child maltreatment are risk factors, while findings on parenting behavior and disciplinary strategies are mixed. Peer influence, exposure to media violence, gender role socialization, and change in family structure can potentially increase the risk of parent abuse. Practice and research implications are also discussed. An ecological systems framework allows for an examination of how various contexts interact and influence parent abuse behavior, and can provide needed directions for further research. PMID:22160270

    This study compared physical child abuse and teacher harassment of bully-victims with other groups and examined their associations with mental health problems in bully-victims. For 6,160 adolescents, experiences of physical child abuse, teacher harassment, peer bullying, and six mental health problem indicators were assessed. Adolescents that had experienced physical child abuse and teacher harassment were more likely to be bully-victims but not neutral or pure victims. Adolescents who reported physical child abuse were more likely to be bully-victims but not pure bullies. Bully-victims that had experienced teacher harassment exhibited more severe depression and insomnia than did those without teacher harassment. Gender had moderating effects on the difference in physical child abuse between bully-victims and neutrals and on the association between physical child abuse and suicidality in bully-victims. Physical child abuse and teacher harassment should be considered when preventive and intervention programs are developed for adolescents. PMID:25300192

    The purpose of this study was to examine gender-based differences in abuse-related characteristics and post-abuse psychiatric disorders among sexually abused children and adolescents. The researchers retrospectively examined files, judicial reports, and social examination reports of 1,250 sexually abused youth cases. Results showed that boys were more often victimized by penetration, force, and physical violence. Incidence of sexual abuse by family members, familiar persons, and multiple persons was higher among girls. In addition, a higher rate of major depressive disorder as well as alcohol consumption and cigarette smoking were found in sexually abused girls. No difference was observed between boys and girls in terms of post-traumatic stress disorder, conduct disorder, and other mental disorders. Intellectual disability was more frequent in boys.

    Full Text Available Adolescence is defined as the period of transition from childhood to adulthood in terms of physical, sexual, cognitive and psychosocial development. Adolescence period can be investigated in three phases which are early adolescence, middle adolescence and late adolescence. Physical and mental maturity is reached in late adolescence and the sexual behavior of the child changes from individual to socially shared relationships. There are some researches which show the increase of sexual abuse in adolescence. In these researches, importance of forensic and medical evaluation is emphasized in situations where sexual abuse of a psychosocially immature child by an adult exists. During forensic and medical evaluation, protecting every kind of material which can be used as medical evidence, and structuring the inspection as soon as possible is very important in order to not only preserve the rights of the attacked person, but also to identify the attacker. In forensic and medical evaluation, preparation of judicial report by doctors, who were assigned as medical referees, collaborating with doctors from different specialty areas in medicine is very important. During the evaluation of physical and mental symptoms in the sexually abused adolescent forensic and psychiatric examination is also needed. To be able to reintegrate child to the society, carrying out the medicalevaluation by an experienced team composed of forensic science experts, psychiatrists, psychologists, pedagogues, and social service experts is very important.

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.

    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. PMID:24661691

    2007-02-01

    The authors examined the reciprocal relations between rumination and symptoms of depression, bulimia, and substance abuse with longitudinal data from 496 female adolescents. Rumination predicted future increases in bulimic and substance abuse symptoms, as well as onset of major depression, binge eating, and substance abuse. Depressive and bulimic, but not substance abuse, symptoms predicted increases in rumination. Rumination did not predict increases in externalizing symptoms, providing evidence for the specificity of effects of rumination, although externalizing symptoms predicted future increases in rumination. Results suggest rumination may contribute to the etiology of depressive, bulimic, and substance abuse pathology and that the former two disturbances may foster increased rumination. Results imply that it might be beneficial for prevention programs to target this cognitive vulnerability. PMID:17324030

  2. Emergence of sex differences in the development of substance use and abuse during adolescence.

    Substance use and abuse begin 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

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.

    Adolescents exposed to domestic violence are at high risk for dating abuse. This randomized controlled trial evaluated a dating abuse prevention program designed specifically for this risk group. Moms and Teens for Safe Dates consisted of six mailed booklets of dating abuse prevention information and interactive activities. Mothers who had been victims of domestic violence but no longer lived with the abuser delivered the program to their adolescents who had been exposed to the abuse. Mother and adolescent pairs (N = 409) were recruited through community advertising; the adolescents ranged from 12 to 16 years old and 64 % were female. Mothers and adolescents completed baseline and 6-month follow-up telephone interviews. Booklet completion in the treatment group ranged from 80 % for the first to 62 % for the last booklet. The analyses first tested whether program effects on dating abuse varied by four a priori identified moderators (mother's psychological health, the amount of adolescent exposure to domestic violence, and adolescent sex and race/ethnicity). Main effects of the program were examined when there were no differential program effects. Program effects on psychological and physical victimization and psychological and cyber perpetration were moderated by the amount of adolescent exposure to domestic violence; there were significant favorable program effects for adolescents with higher, but not lower levels of exposure to domestic violence. There were no moderated or main effects on sexual violence victimization and perpetration or cyber victimization. The findings suggest that a dating abuse prevention program designed for adolescents exposed to domestic violence can have important positive effects. PMID:25776110

    Durr, Marlese; Small, La Fleur F; Dunlap, Eloise

    2010-06-01

    Lula Beatty (2003:59) asks, "What makes a black woman, voluntarily take a substance into her body which alters her perceptions and feelings of well-being?" This research examines African American women's substance abuse as a response to stressful life events grounded in adolescence, drawing in part on the cognitive-transactional approach and distal stressor model to discuss the effects of stressors on mental health and substance abusing behavior. Most respondents viewed their adolescent experiences and the associated stress as tribulations or lessons to be lived through, rather than a signal of needed change in their social, cultural, and ecological life circumstances. The effect of exposure to constant stressors early in the life course coupled with proximal stressors often resulted in negative active responses to stress (i.e. substance abuse) and continued stunted emotional growth. Thus, our findings indicate that the experience of African American women as adolescents contributes to understanding substance abuse amongst this population. These findings further help develop the cognitive-transactional model, while adding to the distal stressors and life process model as a way of considering gender, race, and structural forces.

    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 Abstract Aim Inhalant abuse is a prevalent and often overlooked form of substance abuse in adolescents. Chronic inhalant abuse can damage respiratory, cardiac, renal, hepatic, and neurologic systems. This study aims to determine the physiologic effects of inhaling solvents on the respiratory functions. Methods The general health status of the subjects was assessed by history taking, physical examination and a questionnaire which was designed to show the severity of respiratory symptoms. Spirometry, ventilation/perfusion scintigraphy, and high resolution computed tomography (HRCT were performed to assess pulmonary functions and anatomy. Results Thirty-one male volatile substance abusers and 19 control subjects were included in the study. The mean age of onset of inhalant use was 14.6 ± 2.2 (9-18 years and duration of drug use was 3.7 ± 1.7 years. The most common respiratory symptoms in volatile substance abusers were nasal congestion (45.2%, sputum (38.7%, exercise intolerance (32.3% and cough (22.6%. Results of spirometric studies showed 12 (41.4% subjects with low FVC values Conclusion This study has shown a positive correlation between volatile substance abuse and the development of restrictive ventilatory pattern, but more comprehensive studies are needed for more precise conclusions.

    This study examined the relationship between the characteristics of childhood sexual abuse (CSA) and the severity of consequent posttraumatic stress disorder (PTSD), depression, suicidal ideation, and substance use in a sample of 83 female adolescents aged 13-18 years seeking treatment for PTSD. Nearly two-thirds of the sample (60.7%, n = 51) reported the perpetrator of the CSA was a relative. A large portion (40.5%, n = 34) of the sample reported being victimized once, while almost a quarter of the sample reported chronic victimization (23.8%, n = 20). PTSD and depression scores were in the clinical range, whereas reported levels of suicidal ideation and substance use were low. The frequency of victimizations was associated with suicidal ideation. Contrary to expectation, CSA characteristics including trauma type, perpetrator relationship, and duration of abuse were unrelated to PTSD severity, depressive symptoms, or substance abuse.

    Full Text Available Background: Inhalant use, an important, yet-under recognized form of substance abuse has been reported commonly among adolescents in India but the true extent of the problem is not known due to paucity of data. Aims: To assess the prevalence and determinants of inhalant substance used amongst the adolescents in Manipur. Settings and Design: This cross sectional study was conducted among 1671 adolescent studying in Eighth to Twelfth standard in schools of Imphal-East District Manipur, India during March to June 2013. Materials and Methods: Schools were selected by simple random method and a semi-structured self-administered questionnaire adapted from the 'UNDCP/WHO Global initiative on Primary Prevention of substance abuse' was used for data collection. Univariate and Multiple logistic regression analysis were performed for association between ever users and selected variables. Results: Mean (SD age of the students was 14.5(1.32 years, with males constituting 923(55.2%. Prevalence of ever users was186 (11.1% and glue/dendrite was the commonest substance abused 98(52.7%. Being male, belonging to joint family and increase in age were found to have significant higher risk of being a user, whereas higher level of parental education shows a protective effect. Conclusion: An increased effort for prevention, treatment along with sensitization of parents and teachers is a distinct challenge for policy makers.

    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.

    In contrast to previous research on parental drug abuse, the present study examined comorbid drug addiction and HIV infection in the father as related to his adolescent child's psychological distress. Individual structured interviews were administered to 505 HIV-positive and HIV-negative drug-abusing fathers and one of their children, aged 12-20. Structural equation modelling tested an hypothesized model linking paternal latent variables, ecological factors and adolescent substance use to adolescent distress. Results demonstrated a direct pathway between paternal distress and adolescent distress, as well as an indirect pathway; namely, paternal distress was linked with impaired paternal teaching of coping skills to the child, which in turn was related to adolescent substance use and, ultimately, to the adolescent's distress. There was also an association between paternal drug addiction/HIV and adolescent distress, which was mediated by both ecological factors and adolescent substance use. Findings suggest an increased risk of distress in the adolescent children of fathers with comorbid drug addiction and HIV/AIDS, which may be further complicated by paternal distress. Results suggest several opportunities for prevention and treatment programmes for the children of drug-abusing fathers. PMID:18278619

    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. PMID:26990389

    Although many studies have examined the relationship between early deviant behavior and subsequent life problems among adolescents drawn from the general population, such relationships have not been examined for youth attending substance abuse treatment. Based on in-depth psychosocial assessments conducted with adolescents entering an outpatient substance abuse treatment program (N = 193), the current study examines individual characteristics, life circumstances, and other behavioral and psychological characteristics that are correlated with the age at which these youth initiated substance use and criminal activity. Early onset of substance use was associated with greater levels of family deviance and a variety of problems including school adjustment, drug use, criminal involvement, bullying and cruelty to people and animals, and involvement in risky sexual activities. In contrast, early onset of crime was related only to male gender, early onset of substance use, and cruelty to people. Findings suggest that treatment providers may need to consider the ages at which their adolescent clients initiated substance use given its association with illegal activity, other deviant behavior, and precocious and high-risk sexual behaviors.

    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. PMID:26241375

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

    Science.gov (United States)

    Botvin, G J

    1983-01-01

    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

    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.

    Psychiatric comorbidity and impaired emotional functioning have been previously reported in adult substance abusers but have been less well documented in adolescents. Thus, we investigated mental health problems and emotion regulation abilities in adolescents and young adults with cannabis dependence. Moreover, we explored the relationships between consumption modalities and affective style. Therefore, 32 cannabis abusers (CA) and 30 healthy controls completed a battery of self-reports measuring depression (BDI-13), anxiety (STAI-Y), alexithymia (TAS20; BVAQ-B), anhedonia (PAS; SAS), and sensation seeking (SSS). The MINI was administered to evaluate cannabis dependence and axis I DSM-IV comorbid diagnoses. A semi-structured clinical interview was given to determine psychoactive substance use. Statistical analyses revealed that more than half of the CA reported at least one other non-drug or alcohol comorbid diagnosis. The most common were mood and anxiety disorders. CA subjects scored significantly higher on all affective dimensions except alexithymia total scores; however, they had greater scores for the two subscales measuring the difficulties in identifying feelings. Logistic regressions demonstrated that CA subjects were more likely to experience high levels of trait anxiety, physical anhedonia and sensation seeking than the controls. Various correlations were observed between the affective scores and the substance considered. The amount of substance use and, particularly, the prevalence of polydrug use we observed are alarming. This study demonstrates that cannabis dependence in adolescents and young adults is related to a great psychological distress and specific emotional dimensions and puts emphasis on the importance of substance use prevention as early as middle school.

    This article explores the process of recovering from sexual abuse according to children and adolescents who have been sexually abused and have successfully completed psychotherapy. In this qualitative study, interviews were conducted with 20 participants from 8 to 18 years of age and then subject to narrative analysis. Results show that participants' narratives of recovery involve an improvement of psychological well-being. Moreover, they feel better equipped to overcome future challenges, feeling empowered and able to retake control of their lives. Factors that support and inhibit recovery are examined, as are developmental differences. Discussion underlines the valuable role of psychotherapy in helping children and adolescents in their healing process, changing the meaning of the abusive experience, and developing new capacities.

    The role of disclosure on psychological well-being of adolescents with child sexual abuse experience was investigated in a subsample of 74 disclosers among 800 adolescents recruited in the community in Hong Kong. The results supported that CSA experiences have differential impact on adolescents' psychological well-being. Family characteristics of the disclosers accounted for only a small amount of the variance in an array of psychological well-being measures. CSA characteristics were robust predictors of disclosers' sexual eroticism and externalizing behavioral symptoms. Disclosers' cognitive appraisal of CSA experience and quality of parental attachment were strong predictors of their self-esteem and internalizing behavioral problems. After controlling for the aforementioned factors, negative disclosure experience still significantly predicted lower self-esteem, higher sexual anxiety, more internalizing behavior, and more severe post-traumatic stress disorder responses. Research to understand the factors that generate negative disclosure experiences is needed for developing effective intervention strategies to mitigate the negative consequences of disclosure.

    This study examined a broad variety of adverse childhood experiences in a consecutive sample of female adolescent inpatients with borderline personality disorder (BPD; n = 44) compared with a clinical control (CC; n = 47) group with mixed psychiatric diagnoses. BPD was diagnosed using a structured clinical interview; different dimensions of childhood adversity were assessed using the Childhood Experiences of Care and Abuse Questionnaire, the Parental Bonding Instrument, and the Family Assessment Device. A history of childhood adversity was significantly more common in patients with BPD than in the CC group. Using a multivariate model, sexual abuse (OR = 13.8), general family functioning (OR = 8.9), and low maternal care (OR = 7.6) were specific and independent predictors of adolescent BPD. The results increase our knowledge of the specific role of different dimensions of childhood adversity in adolescent BPD. They have important implications for prevention and early intervention as they highlight the need for specific strategies for involving the family. PMID:25905734

    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.

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 Currently, there is no standardized protocol for the evaluation of situations of sexual abuse. Thus, this study investigated the techniques used by psychologists in forensic examinations in cases of suspected child and adolescent sexual abuse in the context of the criminal investigation. Semi-structured interviews, which were qualitatively analyzed using the WebQDA software, were applied with twelve psychologists who work as expert witnesses in the Medical-Legal Institute of six Brazilian capitals. The results showed a diversity of actions taken in the forensic examination practice, as well as consensus and controversy regarding the use of psychological testing and the credibility assessment of the report. Flexibility in conducting the forensic examinations by the teams was also observed, with the techniques used adapted according to the needs. The importance of the diversity of techniques was highlighted, as these aim to assist the expert witness to come to reliable conclusions, as well as maintain the rigor and technical quality of the evaluation.

    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.

    Wang, Meme; Kviz, Frederick J; Miller, Arlene M

    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.

    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.

    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." PMID:25548142

  13. Adolescent suicide in New York City: plenty of room for new research.

    2012-01-01

    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. PMID:22909918

  14. Inflation Expels Runaways

    CERN Document Server

    Bachlechner, Thomas C

    2016-01-01

    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.

  19. Theory of runaway electrons

    International Nuclear Information System (INIS)

    This paper treats the problem of electrons moving through an infinite gas of positive ions under the influence of a static uniform electric field of arbitrary strength. In evaluating the electrical conductivity of such a gas the conventional treatment involves a perturbation solution of the time-independent Boltzmann equation, and results in the well-known (temperature)3/2 law. Two assumptions are basic to these treatments: 1) that a steady state electron velocity distribution is attained several mean-free collision times after the electric field is applied, and 2) that the terminal electron drift velocity is small compared to the average random electron speed. Both assumptions are avoided in this paper. In the next section the problem is formulated starting with the Boltzmann equation and a review of approximate analytic solutions appropriate to the weak and strong electric field cases is presented. We then describe a time-dependent numerical solution to the Boltzmann equation and compare these results with the approximate solutions. All of these treatments lead to the conclusion that this problem does not admit a time-independent solution. Because of the strong energy dependence of the Rutherford scattering law, the electron drift velocity is not bounded by a terminal value, rather it grows monotonically with time. This is the so-called runaway effect predicted by Giovanelli. Collective effects, or plasma oscillations, are ignored in this work, although these undoubtedly play an important role in the conduction of electricity through the plasma

    Background Physical, emotional and sexual abuse of children is a major problem in South Africa, with severe negative outcomes for survivors. To date, no known studies have used data directly obtained from community-based samples of children to investigate prevalence, incidence, locations and perpetrators of child abuse victimisation. This study aims to investigate prevalence and incidence, perpetrators, and locations of child abuse victimisation in South Africa using a multicommunity sample. Methods 3515 children aged 10–17 years (56.6% female) were interviewed from all households in randomly selected census enumeration areas in two South African provinces. Child self-report questionnaires were completed at baseline and at 1-year follow-up (96.7% retention). Results Prevalence was 56.3% for lifetime physical abuse (18.2% past-year incidence), 35.5% for lifetime emotional abuse (12.1% incidence) and 9% for lifetime sexual abuse (5.3% incidence). 68.9% of children reported any type of lifetime victimisation and 27.1% reported lifetime multiple abuse victimisation. Main perpetrators of abuse were reported: for physical abuse, primary caregivers and teachers; for emotional abuse, primary caregivers and relatives; and for sexual abuse, girlfriend/boyfriends or other peers. Conclusions This is the first study assessing current self-reported child abuse through a large, community-based sample in South Africa. Findings of high rates of physical, emotional and sexual abuse demonstrate the need for targeted and effective interventions to prevent incidence and re-victimisation. PMID:26962202

    Although attachment representation is considered to be disturbed in traumatized adolescents, it is not known whether this is specific for trauma, as comparative studies with other clinical groups are lacking. Therefore, attachment representation was studied by means of the Adult Attachment Interview in adolescents with Childhood Sexual Abuse (CSA) (N = 21), clinical depression (N = 28) and non-clinical controls (N = 28). Coherence of mind and unresolved loss or trauma, as well as the disorganized attachment classification differentiated the CSA group from the clinical depression group and controls, over and above age, IQ, and psychiatric symptomatology. In the current era of sustained criticism on criteria-based classification, this may well carry substantial clinical relevance. If attachment is a general risk or vulnerability factor underlying specific psychopathology, this may guide diagnostic assessment as well as treatment. PMID:26047034

    This study explores the association of child sexual abuse (CSA) with subsequent health risk behaviors among a cross-section of 4354 adolescents and young adults surveyed in urban and rural Taipei. Descriptive analysis and logistic regressions were employed. The overall proportion of CSA was 5.15%, with more females (6.14%) than males (4.16%) likely to experience CSA. CSA was differently associated with multiple adverse health outcomes, after adjusting other factors, such as age, residence, economic status, education, employment status, and household instability. Both males and females with CSA experience were more likely to report drinking, gambling, and suicidal ideation compared with those who had no history of CSA. However, the significant association between CSA and smoking, fighting, and suicidal attempt was not observed among females. Effective interventions are needed to reduce CSA and its adverse effects on adolescent well-being. PMID:25720535

    Morphine sulfate misuse is essentially observed among regular heroin injectors. To our knowledge, primary addiction to morphine sulfate is exceptional, especially among young adolescents. A 13-year-old girl, with no history of addiction, was found dead with three empty blisters of Skenan(®) LP 30 mg at her side. Opiates were detected in biological fluids and hair by chromatographic methods. Blood analyses confirmed morphine overdose (free morphine: 428 ng/mL; total morphine: 584 ng/mL) and segmental hair analysis confirmed regular exposure over several months (maximum morphine concentration 250 pg/mg). Suspecting the victim's mother of recreational use of Skenan(®), the magistrate ordered analysis of her hair, with negative results. From an epidemiological viewpoint, this case of oral morphine sulfate abuse in an adolescent with no previous history suggests the emergence of a new trend of morphine sulfate consumption. From a toxicological viewpoint, it demonstrates the value of hair testing, which documented the victim's regular exposure and made an important contribution to the police investigation.

    This study seeks to determine whether white matter integrity in the brain differs between adolescents with post-traumatic stress disorder (PTSD) due to childhood sexual abuse (CSA) and matched healthy adolescents and whether there is a relationship between white matter integrity and symptom severity in the patient group. Using 3T diffusion tensor imaging, we examined fractional anisotropy (FA) in a group of adolescents with CSA-related PTSD (n = 20) and matched healthy controls (n = 20), in a region of interest consisting of the bilateral uncinate fasciculus (UF), the genu, splenium and body of the corpus callosum (CC), and the bilateral cingulum. In addition, we performed an exploratory whole brain analysis. Trauma symptomatology was measured with the Trauma Symptom Checklist for Children (TSCC) to enable correlational analyses between FA differences and trauma symptomatology. The PTSD group had significantly lower FA values in the genu, midbody and splenium of the CC in comparison with controls (p Post hoc analyses of the eigenvalues of the DTI scan showed increased radial and mean diffusivity in the patient group. In addition, we found a significant negative correlation between scores on the anger subscale of the TSCC and FA values in the left body of the CC in patients (p trauma exposure affects the development of the CC, which may play a role in the pathophysiology of PTSD in adolescents.

  7. Thermonuclear Runaway model

    International Nuclear Information System (INIS)

    The nova outburst requires an energy source that is energetic enough to eject material and is able to recur. The Thermonuclear Runaway (TNR) model, coupled with the binary nature of nova systems satisfies these conditions. The white dwarf/red dwarf binary nature of novae was first recognized as a necessary conditions by Kraft. The small separation characteristic of novae systems allows the cool, red secondary to overflow is Roche lobe. In the absence of strong, funneling magnetic fields, the angular momentum of this material prevents it from falling directly onto the primary, and it first forms a disk around the white dwarf. This material is eventually accreted from the disk onto the white dwarf. As the thickness of this hydrogen-rich layer increases, the degenerate matter at the base reaches a temperature that is high enough to initiate thermonuclear fusion of hydrogen. Thermonuclear energy release increases the temperature which in turn increases the energy generation rate. Because the material is degenerate, the pressure does not increase with temperature, which normally allows a star to adjust itself to a steady nuclear burning rate. Thus the temperature and nuclear energy generation increase and a TNR results. When the temperature reaches the Fermi temperature, degeneracy is lifted and the rapid pressure increase causes material expansion. The hydrogen-rich material either is ejected or consumed by nuclear burning, and the white dwarf returns to its pre-outburst state. The external source of hydrogen fuel from the secondary allows the while process to repeat. 43 refs., 8 figs

    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.

  9. Behaviour of disruption generated runaways in JET

    International Nuclear Information System (INIS)

    Experiments have established the regions of parameter space in JET that lead to runaway generation in disruptions. Previous measurements on the structure of the runaway beam have been confirmed. The delay in runaway generation following temperature collapse is found to be caused by the very high density generated by the disruption. It is shown that runaway generation in JET can be best modelled and understood by including avalanche processes. (author)

    Full Text Available This descriptive study explored the relationship between client and counselor perceptions of the working alliance and the interpersonal relationship dimensions of affiliation and control, and evaluated the relationship of perceptions of the alliance and of client and counselor interpersonal reactions to each other to client outcome after 3-6 months of treatment for substance abuse. Clients were 39 adolescents. Client and counselor ratings of the working alliance (using the Working Alliance Inventory-WAI and interpersonal appraisals of each other (using the Impact Message Inventory Circumplex-IMI-C were obtained during the second week of treatment. Outcome data using the Global Appraisal of Individual Needs (GAIN and the Child and Adolescent Functional Assessment Scale (CAFAS were obtained during the second week of treatment and again after three months and six months of treatment. Interpersonally the predominant impact clients and counselors had on each other was friendliness. For both clients and counselors feelings of affiliation with their counterpart was the relationship dimension most strongly associated with the perception of a working alliance. These findings, and significant associations obtained between WAI and IMI measures and outcome measures, have implications for future research on the role of alliance and interpersonal variables in substance abuse clients¿ response to treatment.

    Research shows that drugs and delinquency are frequently linked, the abuse of various types of substance being a widespread practice among young offenders. At the same time, some psychosocial characteristics are associated with both drug abuse and criminal/antisocial behavior. To help us explore the relationship between young offenders' drug abuse and certain psychosocial variables, we examined closed judicial files on young offenders from the Juvenile Justice Service in Jaen (Spain) corresponding to the period 2001 to 2010. From the contents of these judicial files we analyzed demographic variables such as gender and age, as well as psychosocial variables such as drug abuse, peer group, violent behavior, self-control, tolerance to frustration and attributional style. The results show that most of the young offenders use some type of drug, as well as revealing differential patterns of use according to gender. Also observed is a link between drug abuse and deviant peer group, violent behavior and the above-mentioned psychological variables. Finally, we found some differences in these psychological variables depending on the type of drug used. PMID:22508015

    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.

    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.

    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. PMID:25577999

    Full Text Available Psychological assessment done with children and adolescents victims of sexual abuse is still a challenge for professionals due to the complexity of the phenomenon. This article aims to present the results of a psychological assessment method conducted with girls who were victims of sexual abuse. Ten girls with age raging from 9 to 13 years old were evaluated in three individual meetings. The results have shown that the sexual abuse lasted for, at least, one year before it was revealed. The girls presented symptoms of Post-Traumatic Stress Disorder (PTSD, depression and anxiety. The assessment method which was used showed to be efficient, favoring the creation of bonds, the knowledge of the sexual abuse history and the identification of related psychological symptoms.

  14. Runaway electron generation in tokamak disruptions

    International Nuclear Information System (INIS)

    The time evolution of the plasma current during a tokamak disruption is calculated by solving the equations for runaway electron production simultaneously with the induction equation for the toroidal electric field. The resistive diffusion time in a post-disruption plasma is typically comparable to the runaway avalanche growth time. Accordingly, the toroidal electric field induced after the thermal quench of a disruption diffuses radially through the plasma at the same time as it accelerates runaway electrons, which in turn back-react on the electric field. When these processes are accounted for in a self-consistent way, it is found that (1) the efficiency and time scale of runaway generation agrees with JET experiments; (2) the runaway current profile typically becomes more peaked than the pre-disruption current profile; and (3) can easily become radially in the shape of filaments. It is also shown that higher runaway electron generation is expected if the thermal quench is sufficiently fast. (authors)

  15. A model for disruption generated runaway electrons

    International Nuclear Information System (INIS)

    One of the possible consequences of disruptions in tokamaks is the generation of runaway electrons which can impact plasma facing components and cause damage, owing to high local energy deposition. This problem becomes more serious as the machine size and plasma current increase. Since large size and high currents are characteristics of proposed future machines, control of runaway generation is an important design consideration. A lumped circuit model for disruption runaway electron generation indicates that impurity concentration and type, as well as plasma motion, can strongly influence runaway behaviour. A comparison of disruption data from several runs on JET and DIII-D with model results demonstrate the effects of impurities, and plasma motion, on runaway number density and energy. The model is also applied to the calculation of runaway currents for ITER. (author). 16 refs, 13 figs

  16. Passive runaway electron suppression in tokamak disruptions

    International Nuclear Information System (INIS)

    Runaway electrons created in disruptions pose a serious problem for tokamaks with large current. It would be desirable to have a runaway electron suppression method which is passive, i.e., a method that does not rely on an uncertain disruption prediction system. One option is to let the large electric field inherent in the disruption drive helical currents in the wall. This would create ergodic regions in the plasma and increase the runaway losses. Whether these regions appear at a suitable time and place to affect the formation of the runaway beam depends on disruption parameters, such as electron temperature and density. We find that it is difficult to ergodize the central plasma before a beam of runaway current has formed. However, the ergodic outer region will make the Ohmic current profile contract, which can lead to instabilities that yield large runaway electron losses

    2007-06-01

    A new approach to assessing family attachment patterns is presented, using a composite measure of individual attachment representations based on the Bartholomew Attachment Interview. A cluster analysis yielded three different patterns in a sample of N = 37 families with a drug dependent adolescent (age 14 - 25) and both biological parents. A "triangulated" pattern (mothers: preoccupied; fathers: dismissing; adolescents: fearful) was found in 65% of the sample. A total of 19% showed an "insecure" pattern (mothers, fathers, and adolescents: fearful) and 16% a "near-secure" pattern (mothers and adolescents: secure; fathers preoccupied). Preliminary comparisons between these groups indicate differences in comorbid psychiatric disorders, in individual and family functioning, but not in addiction severity. There is a trend towards differences in outcome of family therapy. Implications for treatment and further research are discussed. PMID:17508312

  10. Relativistic runaway electrons in tokamak plasmas

    International Nuclear Information System (INIS)

    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)

    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

    Not everyone exposed to an efficacious human immunodeficiency virus (HIV) intervention will reduce sexual risk behaviors, yet little is known about factors associated with "failure to change" high-risk sexual behaviors post-intervention. History of abuse and polymorphisms in the serotonin transporter gene (5-HTT) may be associated with non-change. The current study sought to identify genetic, life history, and psychosocial factors associated with adolescents' failure to change condom use behaviors post-participation in an HIV prevention intervention. A sub-set of participants from a clinic-based sample of adolescent African-American females (N = 254) enrolled in a randomized trial of an HIV-prevention was utilized for the current study. Forty-four percent did not increase their condom use from baseline levels 6 months after participating in the sexually transmitted infection (STI)/HIV prevention intervention. In multivariable logistic regression analysis, an interaction between abuse and 5-HTTLPR group was significantly associated with non-change status, along with partner communication frequency scores at follow-up. Follow-up tests found that having a history of abuse was significantly associated with greater odds of non-change in condom use post-intervention for only those with the s allele. For those with ll allele, participants with higher partner communication frequency scores were at decreased odds of non-change in condom use post-intervention. Thus, STI/HIV interventions for adolescent females may consider providing a more in-depth discussion and instruction on how to manage and overcome fear or anxiety related to being assertive in sexual decisions or sexual situations. Doing so may improve the efficacy of STI/HIV prevention programs for adolescent women who have experienced abuse in their lifetime. PMID:23479192

    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 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.

    2014-04-01

    The schema therapy model posits that maltreatment generates early maladaptive schemas (EMSs) that lead to the development of emotional disorders throughout the life span. The model also stipulates that temperament moderates the influence of maltreatment on EMSs. This study examines (a) whether emotional abuse perpetrated by parents and peers, both alone and interactively with temperament, predicts the worsening of EMSs; and (b) whether EMSs in turn predict an increase in depressive and social anxiety symptoms in adolescents. A total of 1,052 adolescents (Mage=13.43; SD=1.29) were assessed at three time points, each of which was separated by 6 months. The subjects completed measures of emotional abuse by parents and peers, neuroticism, extraversion, EMSs, depressive symptoms, and social anxiety. The findings indicate that emotional bullying victimization and neuroticism predict a worsening of all schema domains over time. Contrary to expectations, there was no significant interaction between temperament dimensions and emotional abuse. The results confirmed the mediational hypothesis that changes in EMSs mediated the predictive association between bullying victimization and emotional symptoms. This study provides partial support for the schema therapy model by demonstrating the role of emotional abuse and temperament in the genesis of EMSs. PMID:24252743

    Full Text Available Objective: To examine the relationship of eating disorder (ED symptoms with the severity of alcohol use among adolescents in treatment for alcohol and other substance use disorders (AOSUDs. Method: A sample consisted of 177 adolescents who participated in outpatient AOSUD treatment programs in Connecticut. Chi square tests, one-way ANOVAs and Pearson’s correlation coefficients were used to describe the prevalence and correlates of any eating disorders, and the related symptoms. Multivariate regression was used to test the associations between ED symptoms and alcohol consumption. Results: 26.4% of the participants had at least one ED symptom, with the highest number of symptoms occurring in females. The number of ED symptoms was associated with increases in the number of times that they became intoxicated in the year before entering treatment, the number of alcohol-related social problems, and the number of alcohol-related physical symptoms after taking into consideration the effects of age and gender. Conclusions: The prevalence of symptoms of EDs is high in adolescents with AOSUDs, with the number of ED symptoms correlating with increased alcohol consumption. Further studies on the course and treatment of adolescents with AOSUDs and symptoms of EDs are warranted.

  8. Trapped-Electron Runaway Effect

    CERN Document Server

    Nilsson, E; Fisch, N J; Peysson, Y

    2015-01-01

    In a tokamak, trapped electrons subject to a strong electric field cannot run away immediately, because their parallel velocity does not increase over a bounce period. However, they do pinch towards the tokamak center. As they pinch towards the center, the trapping cone becomes more narrow, so eventually they can be detrapped and run away. When they run away, trapped electrons will have very a different signature from circulating electrons subject to the Dreicer mechanism. The characteristics of what are called trapped-electron runaways are identified and quantified, including their distinguishable perpendicular velocity spectrum and radial extent.

  9. Runaway acceleration during magnetic reconnection in tokamaks

    International Nuclear Information System (INIS)

    In this paper, the basic theory of runaway electron production is reviewed and recent progress is discussed. The mechanisms of primary and secondary generation of runaway electrons are described and their dynamics during a tokamak disruption is analysed, both in a simple analytical model and through numerical Monte Carlo simulation. A simple criterion for when these mechanisms generate a significant runaway current is derived, and the first self-consistent simulations of the electron kinetics in a tokamak disruption are presented. Radial cross-field diffusion is shown to inhibit runaway avalanches, as indicated in recent experiments on JET and JT-60U. Finally, the physics of relativistic post-disruption runaway electrons is discussed, in particular their slowing down due to emission of synchrotron radiation, and their ability to produce electron-positron pairs in collisions with bulk plasma ions and electrons

    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.

    We present an incidence analysis of forensic medical examinations at the Afrânio Peixoto Institute of Forensic Medicine in Rio de Janeiro, Brazil, from January to July 2000. A sample of 124 cases of suspected sexual abuse was selected, both male and female, aged 0 to 17 years. Minors from 0 to 14 years of age represented 81.45% of the sample, coinciding with rates from a former study spanning the first quarter of 2000. Other than vaginal rape, young male subjects prevailed in cases of suspected anal, oral, or other forms of sexual violence and comprised 20.97% of the total sample, with no such cases, either male or female, in the 15-17-year group. Most cases of alleged vaginal sexual abuse were detected in the 10-17-year group. 44.36% of the alleged aggressors were related to the victims; non-related aggressors represented 13.71% of the study group. 30.65% of all cases lacked information about the aggressor. Most police complaints were recorded in the North and East Sides of the city of Rio de Janeiro. The present study did not analyze the victims' social, economic, or cultural characteristics.

    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 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.

    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. PMID:25342471

    Experimental results on the position and current control of disruption generated runaway electrons (RE) in FTU are presented. 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.

    The well observed inward drift of current carrying runaway electrons during runaway plateau phase 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 balance between the change in canonical angular momentum and the input of mechanical angular momentum in such a 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 integrating the modified Euler-Lagrange equation over one bounce time. 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 the ideal wall case and no wall case, and the runaway current center displacement as a function of parallel momentum variation is obtained. The time scale of such displacement is estimated by considering effective radiation drag, which shows reasonable agreement with the observed displacement time scale. This indicates that the phase space dynamic studied here plays a major role in the horizontal displacement of runaway electrons during plateau phase. (C) 2016 AIP Publishing LLC.

    This study tested the hypothesis that internalized gender-role personality attributes and gender-role ideology mediate sex differences in alcohol use and drinking problems in a random sample of 1,077 adolescents aged 13 to 19. Results indicated that gender roles substantially, although not completely, mediated the effects of sex on drinking patterns. The relationships between gender roles and alcohol use were largely consistent with the hypothesis that individuals with conventional gender identities conform more closely to cultural norms that condone drinking among males but not among females. However, effects of the gender-linked attributes of expressivity, emotional control, and instrumentality on drinking also may be interpreted within a framework that views them as functional coping styles. Finally, differences between Black and White teens in the relationships between alcohol use and the masculine attributes of instrumentality and emotional control suggest possible race differences in the functional value of these attributes.

  3. Simulation of runaway electrons in Tokamak disruptions

    International Nuclear Information System (INIS)

    Self-consistent modelling of the generation of runaway electrons and the evolution of the toroidal electric field during tokamak disruptions is presented. The process of runaway generation is analysed by combining a relativistic kinetic equation for the electrons with Maxwell's equations for the electric field. Such modelling allows for a quantitative assessment of the runaway generation during disruptions in present day tokamak experiments, and to extrapolate to future tokamaks like ITER. It is found that the current profile can change dramatically during a disruption, such that the post disruption current, carried mainly by the runaway electrons, is significantly more peaked than the current profile before the disruption. In fact, it is found that the central current density can increase in spite of a reduction in the total current. (authors)

  4. Study of runaway electrons in TEXTOR-94

    International Nuclear Information System (INIS)

    For the process of runaway avalanching to become clearly visible during a disruption several conditions have to be fulfilled: a) the presence of high energetic (approx 20 MeV) primary runaway electrons, b) a value for t0 small compared with the current quench time scale, i.e. a low value for Zeff or a sufficiently high Eparallel, c) some intact magnetic surfaces, such that the generated runaway electrons can be confined for a time longer that t0 and finally d) suitable diagnostics, such as the IR synchrotron radiation and ECE diagnostics. In this paper we considered two examples of runaway avalanche during a disruption, when the above mentioned conditions were satisfied

  5. Runaway electrons in TEXT-U

    International Nuclear Information System (INIS)

    Runaway electrons have long been studied in tokamak plasmas. The previous results regarding runaway electrons and the detection of hard x-rays are reviewed. The hard x-ray energy on TEXT-U is measured and the scaling of energy with electron density, ne, is noted. This scaling suggests a runaway source term that scales roughly as ne/1. The results indicate that runaways are created throughout the discharges. An upper bound for Xe due to magnetic fluctuations was found to be .0343 m2/s. This is an order of magnitude too low to explain the thermal transport in TEXT, implying that electrostatic fluctuations are important in thermal transport in TEXT

    I carried out the Adolescent Alcohol Involvement Scale (AAIS), which was developed for screening of alcohol abuse in youth. The subjects are 288 college students (74 boys, 213 girls and unknown 1). In AAIS, the score of 42 or above is defined as indicating alcohol misuse interfering with psychological functioning, social relation, or family living. In this study, students who marked 42 or above are 6 boys (8.1%) and 1 girls (0.5%). The scores of AAIS of boys have a tendency to distribute to a higher side than those of girls and the average scores of AAIS are 30.7 in boys and 26.8 in girls respectively (significant difference, p < 0.01). The average score of AAIS of good health condition students (27.1) was lower than those of bad health condition students (30.9) and normal condition students (28.7) respectively. The average score of AAIS of one's own house students (26.4) was lower than that of lodging house students (29.5). The average score of AAIS of the students belonging to club activity (28.3) was higher than that of the students not belonging to club activity (25.8). The average score of the students belonging to athletic club (29.0) was higher than those of the students belonging to cultural club (26.8) and the students not belonging to club activity (25.8) respectively. The orderliness of AAIS in selection limbs was generally reasonable but the nessity of replace of the selection limbs in the questionnaire seemed to be requested in some cases. The latter facts and the items in which the rates of no answer were high, requested the future investigations. PMID:8940806

All subjects were selected from Hama­dan City (urban area, Iran based on snowball sampling method. Participants were males who used alcohol and illicit drugs in their life (n=398, completed a self-administered questionnaire."nResults: Approximately half of the participants were used to smoke, drink, take marijuana and/or use opium regularly, and one in ten had taken ecstasy or heroine in the last weeks. Tobacco and alcohols were most common substance as a gateway and consequently marijuana and opium were the next substances. Initiation age result for using substance was ages 13 to 18 years. More than 90% classified as group who suffering familial support, 60.8% as low level of religiosity, and 51.5% of partici­pants was external locus of control."nConclusion: Our findings were similar to western countries pattern except that for opium. The high rate substances use by adoles­cents and changes in pattern of use suggests that all drug use need to be taken into account when addressing adoles­cents' substance use. Moreover, research is needed to identify possible mechanisms underlying the association between binge drug uses in the vulnerable groups.

    Suicide represents, in France, the second cause of death in youth aged 15 to 24. Sixteen per cent of juvenile mortality is attributable to suicide. The annual incidence of suicide attempts in this age group is estimated at about 40 000 cases. Jumping from high represents 6% of deaths from suicide: girls resort to this method twice as often as boys. The severity of somatic consequences and the frequency of sequels following a jumping from a window can hold center stage for a long time, at the risk of trivializing the psychopathology underlying such a violent acting-out. These clinical situations particularly involve a multidisciplinary follow up including an early and active participation of psychiatric consultation-liaison teams. Jumping from a window can occur even apart from established mental disorders, such as psychotic or mood disorders. Our four case-reports draw attention to risk factors represented by: substance abuse (alcohol, cannabis, but also cocaine, ecstasy...), the notion of previous suicide attempts and various drive disorders having a self-harm value or displaying an underlying impulsiveness (eating disorders, scarifications, shoplifting, running away...), the precipitating role of a recent loss of a parent or an important removal from family environment, the potential influence, especially in this age group, of spectacular cases of suicide amplified by the Medias ("Werther effect"). Paradoxically, to belong to a well-off milieu can also contribute to the risk of such acting-out, when parents replace affection and availability by an easy access to various consumer goods and a permissive education, thus opening the way to the encounter with different substances.

    The evaluation of treatment fidelity has become increasingly important as the demand for evidence-based practice grows. The purpose of the present study is to describe the psychometric properties of two measures of treatment fidelity that can be used by therapists and supervisors - one for group-based cognitive-behavioral therapy (CBT) and one for combined Substance Education and Twelve-Step Introduction (SET) for adolescent substance use. At the end of group sessions (CBT n=307; SET n=279), therapists and supervisors completed an evaluation measure assessing adherence to certain core components of the intervention. The supervisor version of the fidelity measure also included items for rating the level of competency the therapist demonstrated when providing each component of the intervention. Results from split-half cross-validation analyses provide strong support for an 11-item, three-factor CBT fidelity measure. Somewhat less consistent but adequate support for a nine-item, two-factor SET fidelity measure was found. Internal consistencies ranged from acceptable to good for both the CBT and SET adherence scales and from acceptable to good for the CBT and SET competency scales, with the exception of the CBT practices competency scale. Preliminary validation of the measures suggests that both measures have adequate to strong factor structure, reliability, and concurrent and discriminant validity. The results of this study have implications for research and clinical settings, including the supervision process. PMID:27211991

    Massive runaway positrons are generated by runaway electrons in tokamaks. The fate of these positrons encodes valuable information about the runaway dynamics. The phase space dynamics of a runaway position is investigated using a Lagrangian that incorporates the tokamak geometry, loop voltage, radiation and collisional effects. It is found numerically that runaway positrons will drift out of the plasma to annihilate on the first wall, with an in-plasma annihilation possibility less than 0.1\\%. The dynamics of runaway positrons provides signatures that can be observed as diagnostic tools.

    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.

    For ITER-relevant runaway electron studies, such as suppression, mitigation, termination and/or control of runaway beam, obtaining the runaway electrons after the disruption is important. In this paper we report on the first achieved discharges with post-disruptive runaway electron beam, entitled "runaway plateau", in the COMPASS tokamak. The runaway plateau is produced by massive gas injection of argon. Almost all of the disruptions with runaway electron plateaus occurred during the plasma current ramp-up phase. Comparison between the Ar injection discharges with and without plateau has been done for various parameters. Parametrisation of the discharges shows that COMPASS disruptions fulfill the range of parameters important for the runaway plateau occurrence. These parameters include electron density, electric field, disruption speed, effective safety factor, maximum current quench electric field. In addition to these typical parameters, the plasma current value just before the massive gas injection surpris...

    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 ...

    About 20% of all massive stars in the Milky Way have unusually high velocities, the origin of which has puzzled astronomers for half a century. We argue that these velocities originate from strong gravitational interactions between single stars and binaries in the centers of star clusters. The ejecting binary forms naturally during the collapse of a young (≤1 million years old) star cluster. This model replicates the key characteristics of OB runaways in our galaxy, and it explains the presence of runaway stars of ≥100 solar masses (M(⊙)) around young star clusters, such as R136 and Westerlund 2. The high proportion and the distributions in mass and velocity of runaways in the Milky Way are reproduced if the majority of massive stars are born in dense and relatively low-mass (5000 to 10,000 M(⊙)) clusters.

    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.

    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.

    Full Text Available A avaliação psicológica de crianças e adolescentes vítimas de abuso sexual é um desafio para os profissionais, devido à complexidade do fenômeno. O presente artigo tem como objetivo apresentar os resultados de um modelo de avaliação psicológica. O estudo foi realizado com 10 meninas com idade entre nove e 13 anos. As participantes foram clinicamente avaliadas em três encontros individuais. Os resultados apontaram que a maioria das meninas foi vítima de abuso sexual por pelo um ano até revelarem a situação a alguém. As meninas apresentaram sintomas de transtorno do estresse pós-traumático, depressão e ansiedade. O método de avaliação utilizado mostrou-se efetivo, possibilitando a formação de vínculo, o conhecimento da história do abuso sexual e a identificação dos sintomas psicológicos decorrentes.Psychological assessment done with children and adolescents victims of sexual abuse is still a challenge for professionals due to the complexity of the phenomenon. This article aims to present the results of a psychological assessment method conducted with girls who were victims of sexual abuse. Ten girls with age raging from 9 to 13 years old were evaluated in three individual meetings. The results have shown that the sexual abuse lasted for, at least, one year before it was revealed. The girls presented symptoms of Post-Traumatic Stress Disorder (PTSD, depression and anxiety. The assessment method which was used showed to be efficient, favoring the creation of bonds, the knowledge of the sexual abuse history and the identification of related psychological symptoms.

  19. Children as Prey: A Case of the Utmost. Contemporary Legends of Organ Theft, Children’s Disappearances, Kidnappings, and the Sexual Abuse of Children and Adolescents

    Directory of Open Access Journals (Sweden)

    Véronique Campion-Vincent

    2015-12-01

    Full Text Available This article discusses several sets of rumours and contemporary legends studied by the author since the 1990s. The common theme concerned with children as prey, victims of ruthless predators, unites narratives of organ theft, the social construction of disappearances and kidnappings, and sexual abuse of children and adolescents. In light of these facts, the denial of yesterday has turned into an ever-growing obsession. This paper examines children as prey through three subthemes, attending to the individual features and to the ways they overlap and also engage contemporary anxieties. An overview of recent events in the United Kingdom and France indicates the persistence of some scary and hazardous hypotheses regarding the children as prey theme. The concluding remarks are presented in three parts: first, a review of key transformations in the discourse around the children as prey by the adoption of a different approach; second, an in-depth discussion of the well-known tale of the Slaughter of the Innocents, as always present in the successive sets of accusations linked to the emergence of collective faces of the Evil; and third, an analysis of the concept of the utmost, a special type of the extreme. Finally, the author’s hypotheses on the contemporary obsession with child sexual abuse are presented.

    2000-05-01

    Background: Numerous cutaneous abnormalities have been described in adolescent girls who have been sexually abused. These include bruising, bite marks, cuts, scratches, abrasions, edema, hematomas or other evidence of struggle. Victims frequently shower or bathe excessively in an effort to cleanse their skin following such an unwanted encounter. However, there is a paucity of information in the literature regarding the association of sexual abuse and removal of the superficial layers of the skin as a more desperate attempt by teenagers to rid themselves of the perpetrator. The purpose of this paper is to heighten awareness among practitioners that self-induced cutting and carving of the forearms with scarification may occur as a manifestation of sexual abuse in young women.Methods: A 14-year-old girl was seen in an adolescent medicine consultation setting during the spring of 1999 for evaluation of an anxiety disorder. During the interview the girl related that she had been under considerable stress and that she was having difficulty sleeping. She also had worsening of facial tics that had been previously noted in association with obsessive compulsive behaviors. She had been receiving psychotherapy and was being treated with fluoxetine, but the symptoms were becoming more severe. On examination she appeared very anxious and demonstrated numerous involuntary, repetitive facial grimaces. Similar twitching movements of the neck were also noted. In addition, she had several well healed scars over both forearms. The lesions were linear with a range of one half to one inch in width and three to four inches in length. The remainder of the general physical examination was entirely unremarkable.Results: The etiology of the scars was initially unknown. Upon further questioning the patient was asked directly about what had caused these marks. At that point she broke down and cried as she related that had been sexually assaulted several months earlier. She stated that she

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.

  5. Studies of runaway electron transport in TEXT

    International Nuclear Information System (INIS)

    The transport of runaway electrons is studied by a plasma position shift experiment and by imposing an externally applied perturbing magnetic field on the edge. The perturbing magnetic field can produce either magnetic islands or, with overlapping islands, a stochastic field. Hard X-ray signals are then measured and compared with analytic and numerical model results. Diffusion coefficients in the edge, ∼104 cm2/sec, and inside the plasma, ∼102 - 103 cm2/sec, are estimated. The averaged drift effects are small and the intrinsic magnetic fluctuations are estimated to be r/B0)2 > ∼1--10 at the edge and decreasing inward. Runaway electrons are a good diagnostic of the magnetic fluctuations. It is considered that the magnetic fluctuations have a negligible effect on electron thermal diffusion in the edge plasma

    We present an investigation of the known sample of runaway stars. The orbits of these stars are traced back to their origin in the Galactic disc. The velocity distribution of these stars is compared to theoretical predictions. We conclude that the majority of stars is well explained by the standard binary ejection mechanism (BEM) and the dynamical ejection mechanism (DEM). However, we find a sample of ten stars which has ejection velocities in excess of those predicted by standard scenarios. ...

  8. Experimental study on runaway characteristics of pump system

    International Nuclear Information System (INIS)

    Experiments on runaway characteristics were conducted for two sets of tubular pump systems and two sets of vertical axial pump systems. The measurement results show that at different blade angles the unit runaway speeds are different and increase with the increase of the blade angle. For the same pump system at the same blade angle the unit runaway speeds decrease with decrease of reverse-water-head of the system. The different outflow passages of pumps also caused variation of the unit runaway speeds. Through the calculation of resistance torque the variable factors of runaway speed with same blade angle are analyzed under different operation conditions of reverse-water-head. It is evident that the unit runaway speed obtained from model pump system is applicable and safe for conversion to prototype pump system

    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.

    The adjoint Fokker-Planck equation method is applied to study the runaway probability function and the expected slowing-down time for highly relativistic runaway electrons, including the loss of energy due to synchrotron radiation. In direct correspondence to Monte Carlo simulation methods, the runaway probability function has a smooth transition across the runaway separatrix, which can be attributed to effect of the pitch angle scattering term in the kinetic equation. However, for the same numerical accuracy, the adjoint method is more efficient than the Monte Carlo method. The expected slowing-down time gives a novel method to estimate the runaway current decay time in experiments. A new result from this work is that the decay rate of high energy electrons is very slow when E is close to the critical electric field. This effect contributes further to a hysteresis previously found in the runaway electron population.

    2016-01-01

    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...

  13. Runaway-electron-materials interaction studies

    International Nuclear Information System (INIS)

    During the operation of magnetic fusion devices it has been frequently observed that runaway electrons can cause severe damage to plasma facing components. The energy of the runaway electrons could possibly reach several 100 MeV in a next generation device with an energy content in the plasma in the order of 100 MJ. In this study effects of high energy electron - materials interaction were determined by laboratory experiments using particle beam facilities, i.e. the Electron Linear Accelerator of the Institute of Scientific and Industrial Research of Osaka University and the 10 MW Neutral Beam Injection Test Stand of the National Institute for Fusion Science. The experiments and further analyses lead to a first assessment of the damage thresholds of plasma facing materials and components under runaway electron impact. It was found that metals (stainless steel, molybdenum, tungsten) showed grain growth, crack formation and/or melting already below the threshold for crack initiation on graphite (14-33 MJ/m2). Strong erosion of carbon materials would occur above 100 MJ/m2. Damage to metal coolant channels can occur already below an energy deposition of 100 MJ/m2. The energy deposited in the metal coolant channels depends on the thickness of the plasma facing carbon material D, with the shielding efficiency S of carbon approximately as S∼D1.15.

  14. Numerical analysis on pump turbine runaway points

    International Nuclear Information System (INIS)

    To research the character of pump turbine runaway points with different guide vane opening, a hydraulic model was established based on a pumped storage power station. The RNG k-ε model and SMPLEC algorithms was used to simulate the internal flow fields. The result of the simulation was compared with the test data and good correspondence was got between experimental data and CFD result. Based on this model, internal flow analysis was carried out. The result show that when the pump turbine ran at the runway speed, lots of vortexes appeared in the flow passage of the runner. These vortexes could always be observed even if the guide vane opening changes. That is an important way of energy loss in the runaway condition. Pressure on two sides of the runner blades were almost the same. So the runner power is very low. High speed induced large centrifugal force and the small guide vane opening gave the water velocity a large tangential component, then an obvious water ring could be observed between the runner blades and guide vanes in small guide vane opening condition. That ring disappeared when the opening bigger than 20°. These conclusions can provide a theory basis for the analysis and simulation of the pump turbine runaway points.

  16. Bump formation in the runaway electron tail

    Decker, J; Fülöp, T

    2015-01-01

    Runaway electrons are generated in a magnetized plasma when the parallel electric field exceeds a critical value. For such electrons with energies typically reaching tens of MeV, the Abraham-Lorentz-Dirac (ALD) radiation force, in reaction to the synchrotron emission, is significant and can be the dominant process limiting the electron acceleration. The effect of the ALD-force on runaway electron dynamics in a homogeneous plasma is investigated using the relativistic finite-difference Fokker-Planck codes LUKE [Decker & Peysson, Report EUR-CEA-FC-1736, Euratom-CEA, (2004)] and CODE [Landreman et al, Comp. Phys. Comm. 185, 847 (2014)]. Under the action of the ALD force, we find that a bump is formed in the tail of the electron distribution function if the electric field is sufficiently large. We also observe that the energy of runaway electrons in the bump increases with the electric field amplitude, while the population increases with the bulk electron temperature. The presence of the bump divides the elec...

    It is discovered that the tokamak field geometry generates a pitch-angle scattering effect for runaway electrons. This neoclassical pitch-angle scattering is much stronger than the collisional scattering and invalidates the gyro-center model for runaway electrons. As a result, the energy limit of runaway electrons is found to be larger than the prediction of the gyro-center model and to depend heavily on the background magnetic field.

  5. An Impact Triggered Runaway Greenhouse on Mars

    Science.gov (United States)

    Segura, T. L.; McKay, C. P.; Toon, O. B.

    2004-01-01

    When a planet is in radiative equilibrium, the incoming solar flux balances the outgoing longwave flux. If something were to perturb the system slightly, say the incoming solar flux increased, the planet would respond by radiating at a higher surface temperature. Since any radiation that comes in must go out, if the incoming is increased, the outgoing must also increase, and this increase manifests itself as a warmer equilibrium temperature. The increase in solar flux would correspond to an increase in temperature, which would increase the amount of water vapor in the atmosphere due to increased evaporation. Since water vapor is a greenhouse gas, it would absorb more radiation in the atmosphere leading to a yet warmer equilibrium temperature. The planet would reach radiative equilibrium at this new temperature. There exists a point, however, past which this positive feedback leads to a "runaway" situation. In this case, the planet does not simply evaporate a little more water and eventually come to a slightly higher equilibrium temperature. Instead, the planet keeps evaporating more and more water until all of the planet's available liquid and solid water is in the atmosphere. The reason for this is generally understood. If the planet's temperature increases, evaporation of water increases, and the absorption of radiation increases. This increases the temperature and the feedback continues until all water is in the atmosphere. The resulting equilibrium temperature is very high, much higher than the equilibrium temperature of a point with slightly lower solar flux. One can picture that as solar flux increases, planetary temperature also increases until the runaway point where temperature suddenly "jumps" to a higher value, in response to all the available water now residing in the atmosphere. This new equilibrium is called a "runaway greenhouse" and it has been theorized that this is what happened to the planet Venus, where the surface temperature is more than 700 K

  6. Study of runaway current generation following disruptions in KSTAR

    International Nuclear Information System (INIS)

    The high fraction of runaway current conversion following disruptions has an important effect on the first wall for next-generation tokamaks. Because of the potentially severe consequences of a large full current runaway beam on the first wall in an unmitigated disruption, runaway suppression is given a high priority. The behavior of runaway currents both in spontaneous disruptions and in D2 massive gas injection (MGI) shutdown experiments is investigated in the KSTAR tokamak. The experiments in KSTAR show that the toroidal magnetic field threshold, BT >2 T, for runaway generation is not absolute. A high fraction of runaway current conversion following spontaneous disruptions is observed at a much lower toroidal magnetic field of BT = 1.3 T. A dedicated fast valve for high-pressure gas injection with 39.7 bar is developed for the study of disruptions. A study of runaway current parameters shows that the conversion efficiency of pre-disruptive plasma currents into runaway current can reach over 80% both in spontaneous disruptions and in D2 MGI shutdown experiments in KSTAR.

  9. Disruption runaway modeling, ripple effects and energy limits

    International Nuclear Information System (INIS)

    Several models of runaway electron generation during a disruption are described and applied to the problem of determining the radiation loss and energy limit of runaway electrons. In particular the prediction of orbits and energy limits for proposed ITER design are discussed. It was found that resonance between the electron gyrofrequency and the fundamental ripple frequency can lead to large synchrotron radiation losses and create an upper bound on runaway energy. Interactions with the second harmonic of the ripple field are very sensitive to ripple amplitude and may lead to a further reduction in runaway energy. In ITER this effect can limit the runaway energy to values of 270 MeV. A lump circuit model of the plasma can be used to determine the coupled interactions of the runaway currents with the plasma and control circuit currents. Depending on what is assumed about the perpendicular energy of the runaway electrons. Maximum values of runaway energy predicted for ITER are in the range of 35 to 120 MeV. 4 refs., 15 figs

  10. Thermal effects of runaway electrons in an armoured divertor

    International Nuclear Information System (INIS)

    This report describes the results of a numerical thermal analysis of the heat deposition of runaway electrons accompanying plasma disruptions in a armoured divertor. The divertor concepts studied are carbon on molybdenum and beryllium on copper. The conclusion is that the runaway electrons can cause melting of the armour as well as melting of the structure and can damage the divertor severely. (orig.)

    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.

  13. Runaway breakdown and electric discharges in thunderstorms

    International Nuclear Information System (INIS)

    This review concerns the theory of the avalanche multiplication of high-energy (0.1 - 10 MeV) electrons in a neutral material, a newly discovered phenomenon known as runaway breakdown (RB). In atmospheric conditions RB takes place at electric fields an order of magnitude weaker than those needed for normal breakdown in air. Experimental work of the past few years has shown that RB determines the maximum electric field strength in thunderclouds and is behind a variety of phenomena newly observed in thunderstorm atmosphere, such as giant high-altitude discharges between thunderclouds and the ionosphere, anomalous amplifications of X-ray emission, intense bursts of gamma radiation, etc. These phenomena are becoming increasingly active areas of study. A necessary condition for the occurrence of runaway avalanche is the presence of high energy seed electrons. In the atmosphere, these are cosmic ray secondary electrons. Therefore, the observed effects reflect the close relationship between cosmic rays and electrodynamic processes in the thunderstorm atmosphere. The first laboratory results on RB are also presented. Further studies in this area may be of interest for high-current electronics. (reviews of topical problems)

    Runaway electrons can be generated in tokamak plasmas if the accelerating force from the toroidal electric field exceeds the collisional drag force owing to Coulomb collisions with the background plasma. In ITER, disruptions are expected to generate runaway electrons mainly through knock-on collisions (Hender et al 2007 Nucl. Fusion 47 S128-202), where enough momentum can be transferred from existing runaways to slow electrons to transport the latter beyond a critical momentum, setting off an avalanche of runaway electrons. Since knock-on runaways are usually scattered off with a significant perpendicular component of the momentum with respect to the local magnetic field direction, these particles are highly magnetized. Consequently, the momentum dynamics require a full 3D kinetic description, since these electrons are highly sensitive to the magnetic non-uniformity of a toroidal configuration. For this purpose, a bounce-averaged knock-on source term is derived. The generation of runaway electrons from the combined effect of Dreicer mechanism and knock-on collision process is studied with the code LUKE, a solver of the 3D linearized bounce-averaged relativistic electron Fokker-Planck equation (Decker and Peysson 2004 DKE: a fast numerical solver for the 3D drift kinetic equation Report EUR-CEA-FC-1736, Euratom-CEA), through the calculation of the response of the electron distribution function to a constant parallel electric field. The model, which has been successfully benchmarked against the standard Dreicer runaway theory now describes the runaway generation by knock-on collisions as proposed by Rosenbluth (Rosenbluth and Putvinski 1997 Nucl. Fusion 37 1355-62). This paper shows that the avalanche effect can be important even in non-disruptive scenarios. Runaway formation through knock-on collisions is found to be strongly reduced when taking place off the magnetic axis, since trapped electrons can not contribute to the runaway electron population. Finally, the

  19. 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...

  20. 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.

  1. Runaway studies in the ATF [Advanced Toroidal Facility] torsatron

    International Nuclear Information System (INIS)

    Pulsed torsatrons and heliotrons are susceptible to runaway electron formation and confinement resulting from the inherent good containment in the vacuum fields and the high loop voltages during the initiation and termination of the helical and vertical fields (''field ramping''). Because runaway electrons can cause an unacceptable level of hard X rays near the machine, a runaway suppression system was designed and included in the initial operation of the Advanced Toroidal Facility (ATF). The main component of the system is a rotating paddle that is normally left in the vacuum chamber during the field ramps. This device proved to be very effective in reducing the runaway population. Measurements of hard X rays from ATF have shown that the runaways are produced primarily during the field ramping but that usually a small steady-state runaway component is also present during the ''flat-top'' portion of the fields. The paddle is the main source of the hard X rays (thick-target bremsstrahlung), although other objects in the vacuum chamber also serve as targets for the runaways at various times. The maximum X-ray energy found by pulse height analysis is /approximately/12--15 MeV; the mean energy appears to be a few mega-electron-volts. A noticeable forward peaking of the bremsstrahlung from the paddle is evident. The limiters do not appear to be major sources of bremsstrahlung. 17 refs., 14 figs

  3. Stellar dynamics in young clusters: the formation of massive runaways and very massive runaway mergers

    CERN Document Server

    Vanbeveren, D; Van Bever, J; Mennekens, N

    2007-01-01

    In the present paper we combine an N-body code that simulates the dynamics of young dense stellar systems with a massive star evolution handler that accounts in a realistic way for the effects of stellar wind mass loss. We discuss two topics: 1. The formation and the evolution of very massive stars (with a mass >120 Mo) is followed in detail. These very massive stars are formed in the cluster core as a consequence of the successive (physical) collison of 10-20 most massive stars of the cluster (the process is known as runaway merging). The further evolution is governed by stellar wind mass loss during core hydrogen burning and during core helium burning (the WR phase of very massive stars). Our simulations reveal that as a consequence of runaway merging in clusters with solar and supersolar values, massive black holes can be formed but with a maximum mass of 70 Mo. In small metallicity clusters however, it cannot be excluded that the runaway merging process is responsible for pair instability supernovae or fo...

    Ion runaway in the presence of a large-scale, reconnection-driven electric field has been conclusively measured in the Madison Symmetric Torus reversed-field pinch (RFP). Measurements of the acceleration of a beam of fast ions agree well with test particle and Fokker-Planck modeling of the runaway process. However, the runaway mechanism does not explain all measured ion heating in the RFP, particularly previous measurements of strong perpendicular heating. It is likely that multiple energization mechanisms occur simultaneously and with differing significance for magnetically coupled thermal ions and magnetically decoupled tail and beam ions.

    The present study examines prevalence and correlates of exchanging sex for drugs, money, food shelter, or other favors (sex exchange) among a nationally representative sample of youth and young adults. Adolescents and young adults (n = 11,620, 53% female, 47% male) from the National Longitudinal Study of Adolescent Health were used for the current sample. Participants completed in-home interviews at both waves. Results revealed that sex exchange was reported by 4.9% (n = 569) of the population in wave 2 or wave 3, and 4.6% (n = 26) of those who exchanged sex did so at both waves. More males reported exchanging sex than females (n = 332 versus n = 237). Respondents who reported child sexual abuse were more likely to exchange sex (95% CI 2.51-4.28, p abuse. Both males and females who engaged in sex exchange were at greater risk for sexually transmitted infections; however, the odds of ever exchanging sex were highest among males who ever had gonorrhea (OR = 6.2; 95% CI 3.75-10.3). Although sex exchange has been studied extensively among homeless and runaway youth, the current study reveals sex exchange also occurs in the general population. PMID:27266400

  8. Transits Probabilities Around Hypervelocity and Runaway Stars

    CERN Document Server

    Fragione, Giacomo

    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.

    International Nuclear Information System (INIS)

    We present the first ultraviolet (UV) and multi-epoch optical spectroscopy of 30 Dor 016, a massive O2-type star on the periphery of 30 Doradus in the Large Magellanic Cloud. The UV data were obtained with the Cosmic Origins Spectrograph on the Hubble Space Telescope as part of the Servicing Mission Observatory Verification program after Servicing Mission 4, and reveal no. 016 to have one of the fastest stellar winds known. From analysis of the C IV λλ1548-51 doublet we find a terminal velocity, v ∞ = 3450 ± 50 km s-1. Optical spectroscopy is from the VLT-FLAMES Tarantula Survey, from which we rule out a massive companion (with 2 days -1, suggesting that the star has traveled the 120 pc from the core of 30 Doradus as a runaway, ejected via dynamical interactions.

  10. Naturalness from runaways in direct mediation

    International Nuclear Information System (INIS)

    Postulating that the nonminimal supersymmetric standard model 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 μ/Bμ problem and simultaneously lead to realistic phenomenology. The singlet that couples to the Higgs fields develops a runaway produced by soft interactions and 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 super QCD superpotential leads to large spontaneous R-symmetry breaking, gaugino masses naturally at the scale of the Higgs mass parameters, and the absence of CP violating phases.

    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 objective of this study was to examine the underlying factorial architecture of lifetime DSM-IV alcohol use disorder (AUD) criteria in a population-based sample of adolescent and emerging adult female twins who had ever used alcohol (n=2832; aged 18-25 years), and to determine whether thresholds and factor loadings differed by age. Item response modeling was applied to DSM-IV AUD criteria. Compound criteria (e.g., persistent desire or unsuccessful attempts to quit or cut down) were included as separate items. Of the remaining 16 items, tolerance and use despite physical problems were the most and least commonly endorsed items, respectively. Underlying the items was a single factor representing liability to AUDs. Factor loadings ranged from 0.67 for blackouts to 0.90 for time spent using/recovering from effects. Some items assessing different DSM-IV criteria had very similar measurement characteristics, while others assessing the same criterion showed markedly different thresholds and factor loadings. Compared to that of women aged 21-25 years, the threshold for hazardous use was higher in women aged 18-20 years, but lower for used longer than intended and persistent desire to cut down. After accounting for threshold differences, no variations in discrimination across age groups were observed. In agreement with the extant literature, our findings indicate that the factorial structure of AUD is unidimensional, with no support for the abuse/dependence distinction. Individual components of compound criteria may differ in measurement properties; therefore pooling information from such divergent items will reduce information about the AUD construct.

    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.

    Results of experiments demonstrating the phenomenon of runaway electron breakdown of atmospheric air under laboratory conditions are presented. As the discharge-initiating electron beam of duration ∼50 ps had passed through the electrode gap, a runaway electron avalanche current was detected in the electrode gap downstream of the anode grid and then breakdown occurred with picosecond stability. The maximum electron energy and the duration of the avalanche current corresponded to theoretical notions about the runaway electron breakdown of atmospheric air in a strong electric field. Breakdown did not occur at all or was considerably delayed when no initiating beam was used. -- Highlights: → Runaway electron air breakdown in laboratory experiments is demonstrated. → The discharge is initiated by electron beam of 50 ps duration. → The maximum electron energy and avalanche current duration correspond to the theory.

    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.

    Based on the analysis of data from the numerous dedicated experiments on plasma disruptions in the TEXTOR tokamak the mechanisms of the formation of runaway electron beams and their losses are proposed.

  4. Empirical Quantification of the Runaway Greenhouse Limit on Earth

    Science.gov (United States)

    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. This research was done as part of Maura Dewey's undergraduate honours thesis at the University of Victoria. Refs: Robert T. Pierrehumbert.

  5. Numerical simulation of runaway electron effect on Plasma Facing Components

    International Nuclear Information System (INIS)

    The runaway electron effects on Plasma Facing Components (PFCs) are studied by the numerical analyses. The present study is the first investigation of time-dependent thermal response of PFCs caused by runaway electron impact. For this purpose, we developed a new integrated numerical code, which consists of the Monte Carlo code for the coupled electrons and photons transport analysis and the finite element code for the thermo-mechanical analysis. In this code, we apply the practical incident parameters and distribution of runaway electrons recently proposed by S. Putvinski, which can express the time-dependent behavior of runaway electrons impact. The incident parameters of electrons in this study are the energy density ranging from 10 to 75 MJ/m2, the average electrons' energy of 12.5 MeV, the incident angle of 0.01deg and the characteristic time constant for decay of runaway electrons event of 0.15sec. The numerical results showed that the divertor with CFC (Carbon-Fiber-Composite) armor did not suffer serious damage. On the other hand, maximum temperatures at the surface of the divertor with tungsten armor and the first wall with beryllium armor exceed the melting point in case of the incident energy density of 20 and 50 MJ/m2. Within the range of the incident condition of runaway electrons, the cooling pipe of each PFCs can be prevented from the melting or burn-out caused by runaway electrons impact, which is one of the possible consequences of runaway electrons event so far.

  8. Phase-space Dynamics of Runaway Electrons In Tokamaks

    Energy Technology Data Exchange (ETDEWEB)

    Xiaoyin Guan, Hong Qin, and Nathaniel J. Fisch

    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.

  11. Child abuse

    International Nuclear Information System (INIS)

    Child abuse is common in most, if not all, Western nations; it probably occurs worldwide. It may be a major factor in the increase in violence throughout much of the world. Radiologists who treat children should think of the possibilitys of abuse whenever they diagnose a fracture, intracranial bleed, ar visceral injury, especially when the history is not compatible with their findings. Metaphyseal 'corner' fractures in infants usually are caused by abuse. Less than 20% of abused children, however, present injuries that can be recognized by radiologic techniques. Consequently normal roentgenograms, nuclear medicine scans, ultrasound studies, and computed tomograms do not exclude child abuse. (orig.)

  12. Runaway electrons and plasma turbulence in current ramping by lower hybrid waves in tokamak plasmas

    International Nuclear Information System (INIS)

    The role of runaway electrons in current ramping by lower hybrid waves is discussed. The back emf induced by current ramping using lower hybrid waves produces runaway electrons at such a rate that the rate of change of the current carried by runaways can completely compensate the rf current ramp rate if runaways are well-confined. However, runaway electrons can also destabilize the oblique plasma waves due to their anisotropy. The resulting turbulence can greatly reduce the run-away production rate, enabling the current ramping rate to exceed the above limit

    International Nuclear Information System (INIS)

    The runaway electrons have been measured in combination with hard x-ray detectors and thermographic camera in the HT-7 tokamak. The dynamics of runaways in the core and edge regions is monitored simultaneously. The HXR signals monitor the lost runaways and the dynamics of runaways in the edge region. The maximum energy of runaways in the edge region could be blocked by the resonance of gyromotion with the nth harmonic of the magnetic field ripple. This resonance interaction creates a barrier to a further increase in the energy of runaway electrons. (author)

    1994-01-01

    Kentucky has the fourth highest percentage of infants born to teenage mothers in the US. Risk factors for adolescent pregnancy are poor academic performance, family history of adolescent pregnancy, absence of one or both biological parents in the home, troubled family relationships, family violence, history of substance abuse, and poor self-concept. Pregnancy adds new developmental requirements to the continual developmental crisis of adolescence. Some of these developmental requirements are dealing with pregnancy and birth of a child and peer and family reactions and relationships. Pregnant teens are at high risk for anemia, preeclampsia, preterm delivery, and low birth weight infants. The health care team must assess the abilities, needs, practices, and priorities of teens. Nurses should promote health and positive health practices in teens. They should focus on prevention of adolescent pregnancy and on meeting the needs of pregnant teens. Adolescent pregnancy interventions include education and adolescent-centered special programs. Peer groups, role playing, videos, and computer games are individualized and effective education techniques for teens. Formal adolescent pregnancy prevention programs are abstinence education, knowledge-based programs, and clinic-focused or school-based programs. A combination of approaches is more effective than using just one approach. Adolescent pregnancy prevention interventions should promote the value of education, discourage substance abuse, and provide counseling for victims of child abuse. Pregnant teens should receive prenatal care as soon as possible. One health care agency should combine physical care, psychosocial support, and education for teens. Kentucky schools help pregnant teens continue their education and help them obtain information and support for care for themselves and their babies. Nurses can be effective at reducing the number of unwanted teen pregnancies. PMID:7934083

  17. TIDALLY INDUCED THERMAL RUNAWAYS ON EXTRASOLAR EARTHS: IMPACT ON HABITABILITY

    International Nuclear Information System (INIS)

    We study the susceptibility of extrasolar Earth-like planets to tidal dissipation by varying orbital, rheological, and heat transfer parameters. We employ a three-dimensional numerical method solving the coupled problem of mantle convection and tidal dissipation. A reference model mimicking a plate tectonic regime and reproducing Earth's present-day heat output is considered. Four other models representing less efficient heat transfer regimes are also investigated. For these five initial models, we determine the orbital configurations under which a positive feedback between tidal dissipation and temperature evolution leads to a thermal runaway. In order to describe the occurrence of thermal runaways, we develop a scaling that relates the global dissipated power to a characteristic temperature and to the orbital parameters. For all numerical experiments sharing the same initial temperature conditions, we show that the reciprocal value of the runaway timescale depends linearly on the global dissipated power at the beginning of the simulation. In the plate tectonic-like regime, Earth-like planets in the habitable zone (HZ) of 0.1 Msun stars experience thermal runaways for 1:1 spin-orbit resonance if the eccentricity is sufficiently high (e>0.02 at a 4 day period, e>0.2 at a 10 day period). For less efficient convective regimes, runaways are obtained for eccentricities as low as ∼0.004 at the inner limit of the HZ. In the case of 3:2 spin-orbit resonance, the occurrence of thermal runaways is independent of eccentricity and is predicted for orbital periods lower than 12 days. For less efficient convective regimes, runaways may occur at larger orbital periods potentially affecting the HZ of stars with a mass up to 0.4 Msun. Whatever the convective regime and spin-orbit resonance, tidal heating within Earth-like planets orbiting in the HZ of stars more massive than 0.5 Msun is not significant.

    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. PMID:24648489

    Novel observations of the burst-like runaway electron losses in tokamak disruptions are reported. The runaway bursts are temporally resolved and first-time measurements of the corresponding runaway energy spectra are presented. A characteristic shape and burst to burst changes of the spectra are found. The runaway energy content of the disruptions and the conversion of the predisruptive magnetic energy are estimated. The radial decay of the runaways can be approximated by an exponential distribution. Deriving from the measurements, resistive tearing modes or kink modes are suggested to trigger the formation of the bursts.

    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 ...

  14. Runaway beam studies during disruptions at JET-ILW

    International Nuclear Information System (INIS)

    Highlights: • Runaway electrons (RE) have been obtained at JET-ILW using massive argon injection. • The runaway electron domain entry points are similar between JET-C and JET-ILW. • Inside the runaway electron domain, higher RE currents are observed with JET-ILW. • RE impact has been observed without material melting up to 100 kA RE current. • Heat deposition of 2 ± 1 mm is confirmed by measurements and simulations. - Abstract: Runaway electrons (RE) during disruptions are a concern for future tokamaks including ITER with its metallic wall. Although RE are rare in spontaneous disruptions with the JET ITER-like Wall (JET-ILW), RE beams up to 380 kA were obtained using massive injection (MGI) of argon in JET-ILW divertor discharges. Entry points into the RE domain defined by operational parameters (toroidal field, argon fraction in MGI) are unchanged but higher RE currents have been obtained inside the JET-ILW MGI-generated RE domain when compared to JET-C. This might be due to the influence of the metallic wall on the current quench plasma. Temperatures of 900 °C have been observed following RE impacts on beryllium tiles. Heat deposition depth of ∼2 mm has to be assumed to match the tile cooling time. 3D simulations of the RE energy deposition using the ENDEP/MEMOS codes show that material melting is unlikely with 100 kA RE beams

    We have searched for radio pulsar companions to 40 nearby OB runaway stars. Observations were made at 575 and 770 MHz with the NRAO 140 foot (43 m) telescope. The survey was sensitive to long- period pulsars with flux densities of 1 mJy or more. No pulsar companions to OB runaways were discovered. One previously unknown pulsar was discovered, PSR J2044 +4614, while observing toward target 0 star BD +45°3260. Follow-up timing observations of the pulsar measured its position to high precision, revealing a 9' separation between the pulsar and the target star, unequivocally indicating they are not associated. The pulsar is ordinary, except that its dispersion measure, 315 pc cm-3, is unusually high given its Galactic longitude, l = 85°. The nondetection of pulsars bound to target stars places an upper limit of 8% (95% confidence) for the fraction of runaway OB stars with pulsar companions detectable via pulsed radio emission by surveys such as ours. Assuming standard models for the pulsar beaming fraction and luminosity function, we conclude most OB runaways do not have pulsar companions.

  17. How close is Earth to a runaway greenhouse?

    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...

    Silicon Carbide (SiC) Junction-Field Effect Transistors (JFETs) are attractive devices for power electronics. Their high temperature capability should allow them to operate with a reduced cooling system. However, experiments described in this paper conclude to the existence of runaway conditions in which these transistors will reach destructive temperatures.

  20. Low Simulated Radiation Limit for Runaway Greenhouse Climates

    Terrestrial planet atmospheres must be in long-term radiation balance, with solar radiation absorbed matched by thermal radiation emitted. For hot moist atmospheres, however, there is an upper limit on the thermal emission which is decoupled from the surface temperature. If net absorbed solar radiation exceeds this limit the planet will heat uncontrollably, the so-called \\runaway greenhouse". Here we show that a runaway greenhouse induced steam atmosphere may be a stable state for a planet with the same amount of incident solar radiation as Earth has today, contrary to previous results. We have calculated the clear-sky radiation limits at line-by-line spectral resolution for the first time. The thermal radiation limit is lower than previously reported (282 W/sq m rather than 310W/sq m) and much more solar radiation would be absorbed (294W/sq m rather than 222W/sq m). Avoiding a runaway greenhouse under the present solar constant requires that the atmosphere is subsaturated with water, and that cloud albedo forcing exceeds cloud greenhouse forcing. Greenhouse warming could in theory trigger a runaway greenhouse but palaeoclimate comparisons suggest that foreseeable increases in greenhouse gases will be insufficient to do this.

    Highlights: • Runaway electrons (RE) have been obtained at JET-ILW using massive argon injection. • The runaway electron domain entry points are similar between JET-C and JET-ILW. • Inside the runaway electron domain, higher RE currents are observed with JET-ILW. • RE impact has been observed without material melting up to 100 kA RE current. • Heat deposition of 2 ± 1 mm is confirmed by measurements and simulations. - Abstract: Runaway electrons (RE) during disruptions are a concern for future tokamaks including ITER with its metallic wall.

    Given previous research on depression, history of physical abuse, family order, attachment, and parenting, we hypothesized that the physical abuse-depression relationship would be moderated by (a) family order and (b) attachment, and that (c) attachment and family order would interact significantly in predicting depression. Hypotheses were tested in South Korea in a random cluster sample of 82 youth aged 15-25 who were either themselves North Korean refugees (n=39) or who were born to North Korean refugee mothers in China (n=43). A qualitative interview was used to shed further light on the findings. Family order appears to be a protective factor against depression in that more order is associated with a weakened past abuse-depression relationship. PMID:25712047

    International Nuclear Information System (INIS)

    This paper reports that this study used SPECT to examine patients who have abused drugs to determine whether SPECT could identify abnormalities and whether these findings have clinical importance. Fifteen patients with a history of substance abuse (eight with cocaine, six with amphetamine, and one with organic solvent) underwent SPECT performed with a triple-headed camera and Tc-99m HMPAO both early for blood flow and later for functional information. These images were then processed into a 3D videotaped display used in group therapy. All 15 patients had multiple areas of decreased tracer uptake peppered throughout the cortex but mainly affecting the parietal lobes, expect for the organic solvent abuser who had a large parietal defect. The videotapes were subjectively described by a therapist as an exceptional tool that countered patient denial of physical damage from substance abuse.

    It is a well known fact that drug abuse is most common in early adolescence. The most popular substances among youth are cannabis products (made from Cannabis sativa L., Cannabaceae). The majority of heroin and cocaine addicts have started with marijuana. The aim of this study is to show some psycho-social characteristics of adolescents who abuse cannabis. Research conducted during the year 2001 was epidemiological and prospective. The study group included 600 adolescents of equal gender and age distribution. Q 2000 questionnaire was used, as a comprehensive tool for all aspects of adolescent life. The results show strong peer impact on one's behavior. Youth who use cannabis had 2-3 friends of the same behavior, compared to others who had none. We found positive correlation between life stressful events and cannabis abuse. We also noticed tendency to delinquent behavior related to cannabis abuse (35%). PMID:15771607

  16. High-current runaway electron beam in a tokamak plasma

    International Nuclear Information System (INIS)

    An equilibrium of toroidal plasma with a large electron-beam current has been realized using the runaway effect in a tokamak. Reproducible runaway-mode discharges are obtained with pure hydrogen gas by the help of intense titanium flashing which results in a low electron density. The beam current is estimated to be more than a half of the total toroidal current. The equilibrium of this discharge is maintained by a strong vertical field because the beam pressure gives rise to an additional increase in Shafranov Λ. The beam pressure is estimated to be more than 80% of the total pressure. The kinetic energy and the spatial distributions of beam electrons are studied by seeing X-ray emission from a tungsten wire inserted into the plasma. The increase of Shafranov Λ due to beam pressure is enhanced by puffing gas into the discharge. (author)

    Runaway, massive stars are not among the most numerous. However, the bow shocks built by their supersonic movement in the interstellar medium have been detected in the infrared range in many cases. Most recently, the stellar bow shocks have been proposed as particle acceleration sites, as radio data analysis at high angular resolution have shown. We present results of different manifestations of the stellar bowshock phenomenon, revealed from modern IR databases.
