    PURPOSE: Although the potential consequences of immigration for adolescent problem behaviors have been addressed in many former studies, internationally comparative research is scarce. This study investigated the impact of immigration on four indicators of adolescents' emotional and behavioral...... symptoms than native boys. Furthermore, both second-generation immigrant boys and girls reported higher levels of physical fighting than their native peers, but differences were more pronounced for boys than for girls. CONCLUSIONS: Overall, the results of this study support a risk perspective on the impact...... problems in 10 countries, taking into account gender and immigrant generation as moderating factors. METHODS: Analyses were based on data from 11-, 13-, and 15-year-old adolescents participating in the Health Behavior in School-aged Children study in Denmark, Germany, Greece, Iceland, Ireland, Italy...

    The change in socio-economic status, drastic decrease in living standards, war, and the introduction of sanctions to our country were complicated in addition by a large number of internally displaced people from Kosovo, which culminated with the 1999 NATO bombing. The aim of this investigation was to estimate the influence of internal displacement on the adaptation and mental health of adolescents. The investigation was conducted on 238 adolescents, comprising a control group of 206 adolescents from Belgrade and 32 internally displaced adolescents from Kosovo. A specific questionnaire regarding habits, behaviour, and psychosomatic state was used, as well as the Cornell Medical Index and the Eysenck Personality Questionnaire. Internally displaced adolescents from Kosovo exhibited greater difficulties in adapting and had worse school records than adolescents from Belgrade, one year after the change in their location. Immediately after the NATO bombing, both groups reacted in the same way: they often talked about the events they had survived, they were afraid of the sounds of alarm sirens and of aeroplanes, and in addition had similar dreams (no statistical variation between the groups). Emotional disturbances, one year after the bombing, were not observed in 40.6% of adolescents from Kosovo, compared to the figure of 74.8% for adolescents from Belgrade. Adolescents from Belgrade consumed alcohol significantly more often: 75.7% compared to 56.3% for adolescents from Kosovo. In addition, 20.4% of adolescents from Belgrade consumed psychoactive substances compared to 6.3% of adolescents from Kosovo. There was no significant difference between the examined groups in the total scores on the scale for neuroticism. All in all, the girls from both examined groups displayed neurotic tendencies more frequently than the boys.

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

    Recognizing that adolescents providing or withholding information about their activities is a strong predictor of parental knowledge, this article compares several ideas about what prompts adolescents to disclose information or keep secrets from their parents. Using a sample of 874 Northern European adolescents (aged 12-16 years; 49.8 % were girls), modified cross-lagged models examined parental monitoring (solicitation and monitoring rules), adolescent delinquency, and perceived parental support as predictors and consequences of adolescents disclosing to parents or keeping secrets, with adolescents' acceptance of parental authority as a moderator. Results suggest that, when adolescents view their parents as supportive, they subsequently disclose more and keep fewer secrets. Engaging in delinquent behavior was related reciprocally to keeping secrets. By comparison, the results generally did not support the idea that adolescents who are monitored provide information to parents, even when they accept parental authority. These results suggest that relationship dynamics and adolescents' delinquent behaviors play an important role in adolescents' information management.

    High prevalence rates of depression and anxiety among adolescents underscore the importance of identifying parental and adolescent behaviors that may lessen the risk for these outcomes. Previous research has shown that parental acceptance, parental knowledge, and child disclosure are negatively associated with internalizing behaviors. It is also important to explore the impact of internalizing behaviors on these parental and child constructs. The current study examined longitudinal relationships between parental acceptance, parental knowledge, child disclosure, and internalizing symptoms across a one-year time period. Participants were 358 adolescents (54 % female) and their primary caregivers, who were primarily African American (92 %). Parents and adolescents provided data through face-to-face interviews. Results showed that parental knowledge and parental acceptance predicted child disclosure, and child disclosure predicted parental knowledge one year later. Higher levels of parental acceptance predicted lower levels of adolescent-reported depressive symptoms, while higher levels of parental report of adolescents' internalizing symptoms predicted lower levels of parental knowledge. No differences in the strength of these relationships were found across grade or gender. These findings highlight the role of the adolescent's perceived acceptance by parents in promoting children's disclosure, and the benefits of parental acceptance in decreasing depressive symptoms over time. Overall, these results show the impact that both adolescent and parental behaviors and internalizing behaviors have on each other across time.

    The latest studies and practice guidelines for the treatment of adolescent patients with anorexia nervosa agree in pointing out the key role played by parents in determining the young patients' therapeutic possibilities and outcomes. Still family functioning has usually been studied using only self-reported instruments. The aim of the present study is therefore to investigate the triadic interactions within the families of adolescents with anorexia nervosa using a semi-standardized observational tool based on a recorded play session, the Lausanne Trilogue Play (LTP). Parents and adolescent daughters, consecutively referred to adolescent neuropsychiatric services, participated in the study and underwent the observational procedure (LTP). The 20 families of adolescent girls with anorexia nervosa (restricting type) were compared with 20 families of patients with internalizing disorders (anxiety and depression). The results showed different interactive patterns in the families of adolescents with anorexia nervosa: they had greater difficulties in respecting roles during the play, maintaining the joint attention and in sharing positive affect, especially in the three-together phase (third phase). The majority of these families (12) exhibited collusive alliances. The parental subsystem appeared frequently unable to maintain a structuring role, i.e., providing help, support and guidance to the daughters, while the girls in turn often found it hard to show independent ideas and develop personal projects. Parents experienced difficulty in carving out a couple-specific relational space, from which the ill daughter was at least temporarily excluded also when they were asked to continue to interact with each other, letting the daughter be simply present in a third-part position (fourth phase). The study of the triadic interactions in the families of adolescents with anorexia nervosa may help to shift the attention from the exclusive mother-daughter relation to the involvement

    Chronic pain in childhood and adolescence has been shown to heighten the risk for depressive and anxiety disorders in specific samples in adulthood; however, little is known about the association between a wider variety of chronic pains and internalizing mental health disorders. Using nationally representative data, the objectives of this study were to establish prevalence rates of internalizing mental health disorders (anxiety and depressive disorders) among cohorts with or without adolescent chronic pain, and to examine whether chronic pain in adolescence is associated with lifetime history of internalizing mental health disorders reported in adulthood. Data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) was used (N = 14,790). Individuals who had chronic pain in adolescence subsequently reported higher rates of lifetime anxiety disorders (21.1% vs 12.4%) and depressive disorders (24.5% vs 14.1%) in adulthood as compared with individuals without a history of adolescent chronic pain. Multivariate logistic regression confirmed that chronic pain in adolescence was associated with an increased likelihood of lifetime history of anxiety disorders (odds ratio: 1.33; 95% confidence interval: 1.09-1.63, P = 0.005) and depressive disorders (odds ratio: 1.38; confidence interval: 1.16-1.64, P < 0.001) reported in adulthood. Future research is needed to examine neurobiological and psychological mechanisms underlying these comorbidities.

    Full Text Available Studies regarding the relationship between attachment and psychopathology during adolescence have been performed separately for clinical and nonclinical adolescents and have used different assessment measures, which together might produce a methodological bias that increases the association between attachment and psychopathology. With the aim of avoiding this bias, the present study used identical measures to explore the relationship between attachment styles and internalizing or externalizing symptoms in clinical and nonclinical samples of adolescents. The sample consisted of 258 adolescents, 129 clinical and 129 nonclinical, aged between 14 and 18 years. The adolescents in each sample were matched for age, gender, and socioeconomic status. Attachment was assessed using the CaMir Q-sort, and psychopathological symptoms were assessed by means of the Youth Self Report (YSR. The relationships between attachment and psychopathology were similar for clinical and nonclinical adolescents. A preoccupied attachment style predicted internalizing and externalizing symptoms, somatic complaints, anxious-fearful behavior, verbal aggression, attention-seeking behavior, and thinking problems. Compared to previous studies, this research has made it possible to identify broader, stronger, and more specific associations between preoccupied attachment style and psychopathological symptoms in adolescents.

  20. The Dual Role of Media Internalization in Adolescent Sexual Behavior.

    Science.gov (United States)

    Rousseau, Ann; Beyens, Ine; Eggermont, Steven; Vandenbosch, Laura

    2016-12-16

    Sexualizing media content is prevalent in various media types. Sexualizing media messages and portrayals emphasize unattainable body and appearance ideals as the primary components of sexual desirability. The internalization of these ideals is positively related to self-objectification and sexual body consciousness. In turn, self-objectification and sexual body consciousness affect adolescents' sexual behavior, albeit in opposing directions. While objectifying self-perceptions are linked to higher levels of sexual behavior, body consciousness during physical intimacy is linked to lower levels of sexual behavior. Based on this knowledge, the present three-wave panel study of 824 Belgian, predominant heterosexual adolescents (M age = 15.33; SD = 1.45) proposes a dual-pathway model that investigates two different pathways through which the internalization of media ideals may impact adolescents' sexual behavior. An inhibitory pathway links media internalization to lower levels of sexual behavior through sexual body consciousness, and a supportive pathway links media internalization to higher levels of sexual behavior through self-objectification. Structural equation analyses supported the proposed dual-pathway, showing that the impact of media internalization on adolescents' sexual behavior proceeds through an inhibitory pathway and a supportive pathway. Regarding the supportive pathway, media internalization (W1) positively predicted sexual behavior (W3), through valuing appearance over competence (W2). Regarding the inhibitory pathway, media internalization (W1) positively predicted body surveillance, which, in turn, positively predicted sexual body consciousness (all W2). Sexual body consciousness (W2) is negatively related to sexual behavior (W3). From a sexual developmental perspective, these findings emphasize the importance of guiding adolescents in interpreting and processing sexualizing media messages.

    In this study, we examined longitudinal, person-centered trajectories of acculturation, internalizing symptoms, and self-esteem in 349 Latino adolescents. We compared acculturation measures (time in the US, culture-of-origin involvement, US cultural involvement, for both parents and adolescents); acculturation stressors (perceived discrimination, acculturation conflicts); and family dynamics (parent-adolescent conflict, familism). Results indicated that, over time, Latino adolescents' internalizing problems decreased and their self-esteem increased. However, we showed that increased length of time living in the US was significantly related to lower self-esteem among adolescents. Parent-adolescent conflict was a strong risk factor, which not only directly heightened internalizing symptoms and lowered self-esteem, but also mediated the effects of acculturation conflicts and perceived discrimination on these outcomes. Our findings revealed familism as a cultural asset associated with fewer internalizing symptoms and higher self-esteem. Internalizing symptoms were also minimized by the adolescent's involvement in the US culture whereas bicultural adolescents with high culture-of-origin involvement reported higher self-esteem. We discussed the limitations and implications of this study for future research and practice.

    In expressed emotion (EE) theory, it is held that high EE household environments enhance adolescent psychopathological distress. However, no longitudinal study has been conducted to examine if either the mother's EE or the adolescent's perception of EE predicts adolescent internalizing and externalizing symptom dimensions (an EE effect model) or vice versa (psychopathological effect model) together in one model. To unravel the reciprocal influences of maternal and adolescent perceived EE to adolescent internalizing and externalizing symptom dimensions, we tested two (i.e., one for internalizing and one for externalizing) cross-lagged panel models. In this study, it was found that both internalizing and externalizing symptom dimensions predicted the adolescent's perception of maternal EE as well as the mother's own rated EE criticism over time. The findings of this study should give both researchers and therapists a reason to reevaluate only using the EE effects model assumption in future EE studies.

    We use data from the National Longitudinal Study of Adolescent Health and the Adolescent Health and Academic Achievement Study to estimate how parents' union dissolution influences changes in adolescents' mathematics course work gains, overall grade point average, and course failure rates during a window of approximately 1 year (N = 2,629). A primary purpose of this study is demonstrating the utility of propensity score matching techniques for studying topics such as ours that pose methodological challenges such as dealing with endogeneity and selection bias. We compare propensity score matching techniques to ordinary least squares (OLS) regression methods to show and discuss comparability of results obtained using these different procedures. Findings suggest that associations between parents' union dissolution and achievement may be causal, regardless of method used.

    Cannabis is the illicit substance most widely used by adolescents. Certain personality traits such as impulsivity and sensation seeking, and the subjective effects experienced after substance use (e.g. euphoria or relaxation) have been identified as some of the main etiological factors of consumption. This study aims to categorize a sample of adolescent cannabis users based on their most dominant personality traits (internalizing and externalizing profile). Then, to make a comparison of both profiles considering a set of variables related to consumption, clinical severity and subjective effects experienced. From a cross-sectional design, 173 adolescents (104 men and 69 women) aged 13 to 18 asking for treatment for cannabis use disorder in an Addictive Behavior Unit (UCAD) from the hospital were recruited. For the assessment, an ad hoc protocol was employed to register consumption, the Millon Adolescent Clinical Inventory (MACI) and the Addiction Research Center Inventory (ARCI) 49-item short form were also administered. Factor analysis suggested a two-profile solution: Introverted, Inhibited, Doleful, Dramatizing (-), Egotistic (-), Self-demeaning and Borderline tendency scales composed the internalizing profile, and Submissive (-), Unruly, Forceful, Conforming (-) and Oppositional scales composed the externalizing profile. The comparative analysis showed that the internalizing profile has higher levels of clinical severity and more subjective effects reported than the externalizing profile. These results suggest the need to design specific intervention strategies for each profile.

    Little is known about why some adolescents with internalizing symptoms engage in sexual behaviors that increase their risk for HIV. This study tested a mediation model of internalizing symptoms and safe sex intentions among adolescents receiving mental health treatment. Self-efficacy for HIV prevention, HIV knowledge, and worry about HIV were hypothesized to mediate associations between internalizing symptoms and safe sex intentions among sexually active and non-active adolescents receiving mental health treatment (N = 893, M age = 14.9). Significant indirect effects from internalizing symptoms to safe sex intentions varied according sexual experience: for sexually non-active adolescents, HIV worry and knowledge mediated this link, whereas for sexually active adolescents, HIV self-efficacy was the significant mediator. Increasing both HIV knowledge and self-efficacy for HIV prevention are important targets for HIV prevention with adolescents with internalizing symptoms, and careful attention should be paid towards targeting these interventions to sexually experienced and inexperienced youth.

  13. INTERNAL AUDIT COMPARATIVE ANALYSIS - MANAGEMENT CONTROL CONCEPTS

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Given Romania's integration into the European Union we consider it appropriate to clarify some terms used in auditing activities of both public funds and European funds. International practice requires a clear separation of internal audit activities from other management control concepts and recommend to establish an internal controlling system as well as an internal audit structure under the coordination of the manager as being the only ways cap able to respond to current risks faced by public entities. Internal Audit, along its evolution - characterized by complex dynamics and adaptability - created confusion regarding the concept of control. The research presented in this paper is based on works published to date regarding the conceptual boundaries of this notion.

    The goal of this study was to advance the understanding of separate and joint effects of mothers' and fathers' autonomy-relevant parenting during early and middle adolescence. In a sample of 518 families, adolescents (49 % female; 83 % European American, 16 % African American, 1 % other ethnic groups) reported on their mothers' and fathers' psychological control and knowledge about adolescents' whereabouts, friends, and activities at ages 13 and 16. Mothers and adolescents reported on adolescents' externalizing and internalizing behaviors at ages 12, 14, 15, and 17. Adolescents perceived their mothers as using more psychological control and having more knowledge than their fathers, but there was moderate concordance between adolescents' perceptions of their mothers and fathers. More parental psychological control predicted increases in boys' and girls' internalizing problems and girls' externalizing problems. More parental knowledge predicted decreases in boys' externalizing and internalizing problems. The perceived levels of behavior of mothers and fathers did not interact with one another in predicting adolescent adjustment. The results generalize across early and late adolescence and across mothers' and adolescents' reports of behavior problems. Autonomy-relevant mothering and fathering predict changes in behavior problems during early and late adolescence, but only autonomy-relevant fathering accounts for unique variance in adolescent behavior problems.

    This study examined the relative influence of three parenting behaviors (support, behavioral control, and psychological control) and deviant peers on trajectories of externalizing and internalizing problems in early adolescence. A white, working-to-middle-class sample of adolescents and their mothers and fathers in two-earner families participated in a 32-year longitudinal study (N = 109 families). The study began when the adolescents were in sixth grade (M age = 11.5 years). Analyses showed that parents' firm behavioral control seemed to halt the upward trajectory in externalizing problems among adolescents with deviant peers. Initial levels of internalizing problems were higher among adolescents with parents who reported lower levels of behavioral control and among adolescents with deviant peers. This study suggests that parenting exerts an important influence in adolescents' lives and may do so even in the face of potentially negative peer influence.

    Parents generally take pains to insure that their children adopt their own religious beliefs and practices, so what happens psychologically to adolescents who find themselves less religious than their parents? We examined the relationships among parents' and adolescents' religiousness, adolescents' ratings of parent-adolescent relationship quality, and adolescents' psychological adjustment using data from 322 adolescents and their parents. Adolescent boys who had lower organizational and personal religiousness than their parents, and girls who had lower personal religiousness than their parents, had more internalizing and externalizing psychological symptoms than did adolescents whose religiousness better matched their parents'. The apparent effects of subparental religiousness on adolescents' psychological symptoms were mediated by their intermediate effects on adolescents' ratings of the quality of their relationships with their parents. These findings identify religious discrepancies between parents and their children as an important influence on the quality of parent-adolescent relationships, with important implications for adolescents' psychological well-being.

    Internalizing symptoms such as withdrawn and anxious-depressed behavior are common in adolescence. This prospective longitudinal study helps to gain insight into the development of internalizing behavior, focusing on the role of early parent-child interaction while ruling out genetic similarity as a confounder. More specifically, the central question addressed in this study was whether parental sensitivity and child inhibited temperament predict children's withdrawn and anxious-depressed behavior in middle childhood and adolescence. We followed 160 early-adopted children (53 % girls) from infancy to adolescence. Structural equation modeling was used to test relationships both prospectively and concurrently. The results revealed that more sensitive parenting in infancy and middle childhood predicted less inhibited behavior in adolescence, which in turn predicted fewer internalizing problems in adolescence. The findings suggest that maternal sensitivity lowers adolescents' inhibited behavior and decreases the risk for adolescents' internalizing problem behavior indirectly through lower levels of inhibition. Supporting sensitive parenting in the years before adolescence may protect children from developing inhibited behavior and internalizing behavior problems in adolescence.

    Adolescent girls today suffer from internalizing problems such as somatic symptoms and mental health problems at higher rates compared to those of previous decades, and effective interventions are warranted. The aim of this study was to explore the experiences of participating in an 8-month dance intervention. This qualitative study was embedded in a randomized controlled trial of a dance intervention for adolescent girls with internalizing problems. A total of 112 girls aged 13-18 were included in the study. The dance intervention group comprised 59 girls, 24 of whom were strategically chosen to be interviewed. Data were analyzed using qualitative content analysis with an inductive approach. The experiences of the dance intervention resulted in five generic categories: (1) An Oasis from Stress, which represents the fundamental basis of the intervention; (2) Supportive Togetherness, the setting; (3) Enjoyment and Empowerment, the immediate effect; (4) Finding Acceptance and Trust in Own Ability, the outcome; and (5) Dance as Emotional Expression, the use of the intervention. One main category emerged, Finding Embodied Self-Trust That Opens New Doors, which emphasizes the increased trust in the self and the ability to approach life with a sense of freedom and openness. The central understanding of the adolescent girls' experiences was that the dance intervention enriched and gave access to personal resources. With the non-judgmental atmosphere and supportive togetherness as a safe platform, the enjoyment and empowerment in dancing gave rise to acceptance, trust in ability, and emotional expression. Taken together, this increased self-trust and they discovered a new ability to "claim space." Findings from this study may provide practical information on designing future interventions for adolescent girls with internalizing problems.

Potentially, this contrast provides quite differentiated responses to administrative reform......Over the last few years new practices of spatial strategy making at different planning scales have emerged. At the metropolitan level, such spatial strategies are reminiscent of national and supranational competitive strategies (e.g. EU policies) as well as ratifications of international...... conventions and agreements. A particular feature that metropolitan spatial strategies seem to have in common is the increasingly discretionary planning practices, often, however, within different institutional contexts.

    Thirty-five hospitalized catatonic schizophrenic patients from Sri Lanka were compared with 22 patients in the U.K. and 13 in Canada. The phenomenology was established using the Present State Examination. Results suggest that ethnicity, chronicity of illness and reception of neuroleptic treatment may influence the lower prevalence of catatonic symptoms among the U.K. and Canadian schizophrenics. Onset of illness appears to be among young adults and mutism, stupor, mannerisms, stereotypes and negativism were the common catatonic symptoms observed.

    The present study aimed to investigate the level of self-esteem among religious minority adolescents (Christians and Hindus) by making a comparison with their dominant counterparts (Muslims) in Pakistan. It was hypothesized that adolescents of religious minorities would have lower level of self-esteem than their dominant counterparts. In the present study 320 adolescents participated, in which 160 adolescents belonged to minority religious groups (i.e. 76 Christians and 84 Hindus) and 160 adolescents belonged to dominant religious group i.e. Muslims. To assess self-esteem of the participants, Rosenberg Self-Esteem Scale (Rosenberg in Society and the adolescent self image, Princeton University Press, Princeton, NJ, 1965) was used. One Way Analysis of Variance reveals that religious minority adolescents (Christians and Hindus) inclined to have lower self-esteem as compared to their dominant counterpart (Muslim adolescents).

    Adolescents higher in temperamental withdrawal are at risk for anxiety and depressive symptoms; however, not all youth higher in withdrawal exhibit internalizing symptoms, suggesting that contextual factors may influence these relationships. We examined whether youth withdrawal moderates the relationships between neighborhood processes (crime, social cohesion) and internalizing symptoms and whether findings were consistent with the diathesis-stress or differential susceptibility hypotheses. Participants were 775 adolescents (M = 15.50 ± 0.56 years, 72 % male, 76 % White). Adolescents higher in withdrawal manifested higher internalizing symptoms in the context of lower neighborhood crime and lower neighborhood social cohesion than youth lower in withdrawal, supporting diathesis-stress. These findings elucidate neighborhood processes associated with internalizing symptoms, which can inform models of risk and resilience for these symptoms among children who differ in temperamental withdrawal.

    Parental monitoring and warmth have traditionally been studied in the context of White, middle-class families. This article explores optimal levels of these parenting behaviors in preventing adolescent psychopathology in impoverished, urban high-crime areas while accounting for child perceptions of neighborhood danger. In this study, data were collected longitudinally at 2 time points 1 year apart from a sample of 254 African American young adolescents (T1: M age = 12.6 years, 41% male) and their parents. Parental monitoring and warmth, child perception of neighborhood danger, and child internalizing and externalizing behaviors were measured using questionnaires. Child internalizing behaviors were also measured using a time sampling technique capturing in vivo accounts of daily distress. Findings indicated associations between parental monitoring and children's externalizing behaviors along with linear and quadratic associations between parental monitoring and internalizing behaviors. Monitoring and warmth were differentially related to symptoms depending on neighborhood danger level. When children perceived less danger, more monitoring related to less externalizing. When children perceived more danger, more warmth related to less internalizing. In addition, adolescents' perceptions of neighborhood danger emerged as equally strong as monitoring and warmth in predicting symptoms. This study underscores the influence of carefully considering parenting approaches and which techniques optimally prevent adolescents' externalizing, as well as prevent internalizing difficulties. It also highlights how context affects mental health, specifically how perceptions of danger negatively influence adolescents' psychopathology, emphasizing the importance of initiatives to reduce violence in communities.

    Objective Mean-levels of thin-ideal internalization increase during adolescence and pubertal development, but it is unknown whether these phenotypic changes correspond to developmental changes in etiological (i.e., genetic and environmental) risk. Given the limited knowledge on risk for thin-ideal internalization, research is needed to guide the identification of specific types of risk factors during critical developmental periods. The present twin study examined genetic and environmental influences on thin-ideal internalization across adolescent and pubertal development. Method Participants were 1,064 female twins (ages 8–25 years) from the Michigan State University Twin Registry. Thin-ideal internalization and pubertal development were assessed using self-report questionnaires. Twin moderation models were used to examine if age and/or pubertal development moderate genetic and environmental influences on thin-ideal internalization. Results Phenotypic analyses indicated significant increases in thin-ideal internalization across age and pubertal development. Twin models suggested no significant differences in etiologic effects across development. Nonshared environmental influences were most important in the etiology of thin-ideal internalization, with genetic, shared environmental, and nonshared environmental accounting for approximately 8%, 15%, and 72%, respectively, of the total variance. Discussion Despite mean-level increases in thin-ideal internalization across development, the relative influence of genetic versus environmental risk did not differ significantly across age or pubertal groups. The majority of variance in thin-ideal internalization was accounted for by environmental factors, suggesting that mean-level increases in thin-ideal internalization may reflect increases in the magnitude/strength of environmental risk across this period. Replication is needed, particularly with longitudinal designs that assess thin-ideal internalization across key

  4. Prefrontal Dopaminergic Mechanisms of Extinction in Adolescence Compared to Adulthood in Rats

    Adolescents with anxiety disorders attain poorer outcomes following extinction-based treatment compared to adults. Extinction deficit during adolescence has been identified to involve immaturity in the medial prefrontal cortex (mPFC). Findings from adult rodents suggest extinction involves dopamine signaling in the mPFC. This system changes dramatically during adolescence, but its role in adolescent extinction is unknown. Therefore, we investigated the role of prefrontal dopamine in extinction using Pavlovian fear conditioning in adolescent and adult rats. Using quantitative PCR (qPCR) analyses, we measured changes in dopamine receptor gene expression in the mPFC before and after extinction. We then enhanced dopamine 1 receptor (D1R) or dopamine 2 receptor (D2R) signaling in the infralimbic cortex (IL) of the mPFC using agonists at the time of extinction. Adolescent rats displayed a deficit in extinction retention compared to adults. Extinction induced a reduction in D1R compared to D2R gene expression in adolescent rats, whereas an increase of D1R compared to D2R gene expression was observed in adult rats. Acutely enhancing IL D1R signaling using SKF-81297 had no effect on extinction at either age. In contrast, acutely enhancing IL D2R signaling with quinpirole significantly enhanced long-term extinction in adolescents, and impaired within-session extinction in adults. Our results suggest a dissociated role for prefrontal dopamine in fear extinction during adolescence compared to adulthood. Findings highlight the dopamine system as a potential pharmacological target to improve extinction-based treatments for adolescents. PMID:28275342

  5. Comparing sleep disorders in urban and suburban adolescents

    2014-09-01

    Full Text Available Background Sleep disturbances commonly occur in adolescents. Socioeconomic levels, lifestyle, and urban or suburban environments influence the sleep patterns of adolescents. The modernization process in urban environments is marked by the development of information technology media, and the lack of parental monitoring potentially influencing adolescent sleep disturbances. Sleep disturbances may affect children’s physical growth, as well as their emotional, cognitive, and social development. Objective To assess for sleep disorders in urban and suburban adolescents, and to determine the factors that influence the prevalence of sleep disturbances. Methods A cross-sectional study was conducted on 12 to 15-year-old junior high school students in urban (n=350 and suburban (n=350 environments in the city of Medan, North Sumatera. The study was undertaken from May to June 2010 using the Sleep Disorders Scale for Children (SDSC, a set of questionnaires. The SDSC was filled out by parents based on what they remembered about their children’s sleep patterns in the prior 6 months. Results In the urban group, there were 133 (38.0% subjects with sleep disturbances, 182 (52.0% were borderline, and 35 (10.0% were normal. In the suburban group, there were 132 (37.7% subjects with sleep disturbances, 180 (51.4% were borderline, and 38 (10.9% were normal. The most influential factors for sleep disturbances in urban and suburban youth were environmental noise (P=0.001 and consuming beverages that contain caffeine (P=0.001. There were three types of sleep disorders that significantly found more in urban adolescents: disorders of initiating and maintaining sleep, disorders of excessive somnolence, and sleep hyperhidrosis.

    Full Text Available Abstract Background Recently, attention has been focused on subsequent pregnancies among teenage mothers. Previous studies that compared the reproductive outcomes of teenage nulliparae and multiparae often did not consider the adolescents' reproductive histories. Thus, the authors compared the risks for adverse reproductive outcomes of adolescent nulliparae to teenagers who either have had an induced abortion or a previous birth. Methods In this retrospective cohort study we used perinatal data prospectively collected by obstetricians and midwives from 1990–1999 (participation rate 87–98% of all hospitals in Lower Saxony, Germany. From the 9742 eligible births among adolescents, women with multiple births, >1 previous pregnancies, or a previous spontaneous miscarriage were deleted and 8857 women Results In bivariate logistic regression analyses, compared to nulliparous teenagers, adolescents with a previous birth had higher risks for perinatal [OR = 2.08, CI = 1.11,3.89] and neonatal [OR = 4.31, CI = 1.77,10.52] mortality and adolescents with a previous abortion had higher risks for stillbirths [OR = 3.31, CI = 1.01,10.88] and preterm births [OR = 2.21, CI = 1.07,4.58]. After adjusting for maternal nationality, partner status, smoking, prenatal care and pre-pregnancy BMI, adolescents with a previous birth were at higher risk for perinatal [OR = 2.35, CI = 1.14,4.86] and neonatal mortality [OR = 4.70, CI = 1.60,13.81] and adolescents with a previous abortion had a higher risk for very low birthweight infants [OR = 2.74, CI = 1.06,7.09] than nulliparous teenagers. Conclusion The results suggest that teenagers who give birth twice as adolescents have worse outcomes in their second pregnancy compared to those teenagers who are giving birth for the first time. The prevention of the second pregnancy during adolescence is an important public health objective and should be addressed by health care providers who attend the first birth or the abortion

    Full Text Available Objective: To investigate whether internalizing disorders are associated with quality of life (QoL in adolescents, even after accounting for shared risk factors. Methods: The sample comprised 102 adolescents from a community cross-sectional study with an oversampling of anxious subjects. Risk factors previously associated with QoL were assessed and divided into five blocks organized hierarchically from proximal to distal sets of risk factors. Results: Multiple regression analysis yielded a hierarchical model accounting for 72% of QoL variance. All blocks were consistently associated with QoL (p < 0.05, accounting for the following percentages of variance: 12% for demographics; 5.2% for family environment; 37.8% for stressful events; 10% for nutritional and health habits; and 64.2% for dimensional psychopathological symptoms or 22.8% for psychiatric diagnoses (dichotomous. Although most of the QoL variance attributed to internalizing symptoms was explained by the four proximal blocks in the hierarchical model (43.2%, about 21% of the variance was independently associated with internalizing symptoms/diagnoses. Conclusions: QoL is associated with several aspects of adolescent life that were largely predicted by our hierarchical model. Our findings reinforce the hypothesis that internalizing disorders and internalizing symptoms in adolescents have a high impact on QoL and deserve proper clinical attention.

    Peer victimization experiences represent developmentally salient stressors among adolescents and are associated with the development of internalizing symptoms. However, the mechanisms linking peer victimization to adolescent psychopathology remain inadequately understood. This study examined emotion dysregulation as a mechanism linking peer stress to changes in internalizing symptoms among adolescents in a longitudinal design. Peer victimization was assessed with the Revised Peer Experiences Questionnaire (M. J. Prinstein, J. Boergers, & E. M. Vernberg, 2001) in a large (N = 1,065), racially diverse (86.6% non-White) sample of adolescents 11-14 years of age. Emotion dysregulation and symptoms of depression and anxiety were also assessed. Structural equation modeling was used to create a latent construct of emotion dysregulation from measures of discrete emotion processes and of peer victimization and internalizing symptoms. Peer victimization was associated with increased emotion dysregulation over a 4-month period. Increases in emotion dysregulation mediated the relationship between relational and reputational, but not overt, victimization and changes in internalizing symptoms over a 7-month period. Evidence for a reciprocal relationship between internalizing symptoms and relational victimization was found, but emotion dysregulation did not mediate this relationship. The implications for preventive interventions are discussed.

    Childhood adversity (CA) is strongly associated with youth psychopathology. Identifying factors that reduce vulnerability following CA is critical for developing preventive interventions. Vagal tone and vagal reactivity following psychosocial stressors might influence psychopathology among youths exposed to CA. We acquired heart period and impedance cardiography data to calculate respiratory sinus arrhythmia (RSA) and preejection period (PEP) from 157 adolescents aged 13-17 years at rest and during the Trier Social Stress Test (TSST). Internalizing and externalizing symptoms and multiple forms of CA were assessed. Resting RSA and RSA reactivity interacted with CA in predicting internalizing but not externalizing psychopathology; CA was unassociated with internalizing problems in adolescents with high resting RSA and RSA reactivity. No interactions were observed with PEP. High resting RSA predicted greater vagal rebound and accelerated heart rate recovery following the TSST, highlighting one potential mechanism underlying low internalizing symptoms following CA among youths with high vagal tone.

    Self-consciousness is considered as a multifaceted and hierarchical construct that includes self-evaluation, self-experience, and self-control. This study assumes that self-consciousness is a preventative factor of internalizing and externalizing problems among Chinese adolescents. 1202 Chinese adolescents from grade 7 to grade 12 participated in this study by completing a battery of questionnaires that assessed self-consciousness and internalizing/externalizing problems. The results showed that, after controlling demographic variables, some lower-order factors (i.e., sense of satisfaction, sense of anxiety, social self, self-restraint, self-esteem, and self-monitoring) and higher-order subscales (i.e., self-evaluation and self-experience) of self-consciousness significantly predicted internalizing problems, while externalizing problems were predicted by several lower-order factors (i.e., self-restraint, sense of satisfaction, and self-monitoring) and higher-order subscales (i.e., self-control and self-experience). In conclusion, this study demonstrates that Chinese adolescents' internalizing and externalizing problems are related with different aspects of self-consciousness, which sheds light on the prevention into adolescents' problem behaviors.

    Full Text Available Background: Psychometrically sound measurement instrument is a fundamental requirement across broad range of research areas. In negative affect research, Depression Anxiety Stress Scale (DASS has been identified as a psychometrically sound instrument to measure depression, anxiety and stress, especially the 21-item version. However, its psychometric properties in adolescents have been less consistent. Objectives: Thus, the present study sought to examine the factorial validity and internal consistency of the adapted 21-item version of DASS in Malaysian adolescents. Method: Using cross-sectional study design, DASS-21 was administered to 750 Malaysian adolescents (Mean age = 13.40 ± 0.49. The data were then analyzed using Confirmatory factor analysis (CFA, in which the original DASS-21 factor structure (depression-stress-anxiety was compared to 8 other alternative models.Results: CFA results revealed a weak support for DASS-21 as a differentiated measure of depression, anxiety and stress in Malaysian adolescents. Extremely high latent factors intercorrelations were observed in the model reflecting original DASS factor structure. On the other hand, despite the best overall fit of a 4-factor model consisting of depression, anxiety, and stress, as well as a general negative affect factor, individual factor loadings for the specific factors were uninterpretable. Although model fit of 1-factor model was inferior when compared the other competing models, this model (1-factor exhibit reasonable model fit. Conclusion: We concluded that the use of Malaysian adapted DASS-21 as a differentiated measure stress, anxiety, and depression in Malaysian adolescent should proceed with caution and further refinement of the scale is necessary before a concrete conclusion can be made.

    Objective To investigate whether reported fast-food consumption over the previous year is associated with higher childhood or adolescent body mass index (BMI). Design Secondary analysis from a multicentre, multicountry cross-sectional study (International Study of Asthma and Allergies in Children (ISAAC) Phase Three). Subjects and methods Parents/guardians of children aged 6–7 completed questionnaires which included questions about their children's asthma and allergies, fast-food consumption, height and weight. Adolescents aged 13–14 completed the same questionnaire. The questionnaire asked “In the past 12 months, how often on average did you (your child) eat fast-food/burgers?” The responses were infrequent (never/only occasionally), frequent (once/twice a week) or very frequent (three or more times per week). A general linear mixed model was used to determine the association between BMI and fast-food consumption, adjusting for Gross National Income per capita by country, measurement type (whether heights/weights were reported or measured), age and sex. Results 72 900 children (17 countries) and 199 135 adolescents (36 countries) provided data. Frequent and very frequent fast-food consumption was reported in 23% and 4% of children, and 39% and 13% of adolescents, respectively. Children in the frequent and very frequent groups had a BMI that was 0.15 and 0.22 kg/m2 higher than those in the infrequent group (p<0.001). Male adolescents in the frequent and very frequent groups had a BMI that was 0.14 and 0.28 kg/m2 lower than those in the infrequent group (p<0.001). Female adolescents in the frequent and very frequent groups had a BMI that was 0.19 kg/m2 lower than those in the infrequent group (p<0.001). Conclusions Reported fast-food consumption is high in childhood and increases in adolescence. Compared with infrequent fast-food consumption, frequent and very frequent consumption is associated with a higher BMI in children. Owing to residual

    Internationally adopted adolescents may have more delinquent behavior than non-adopted adolescents. One explanation is these adolescents experience discrimination and loss of culture, and adoptive parents are not adequately addressing these experiences. However, studies have not examined the effects of family discussions of racial and ethnic differences within adoptive families on adopted adolescents' delinquent behavior. To test this relationship, this study utilized data from 111 U.S. internationally adoptive families with 185 South Korean adopted adolescents (55% female, M age = 17.75). During an observational assessment, families discussed the importance of their racial and ethnic differences, and adolescents completed a delinquent behavior questionnaire. Analysis of covariance showed differences in adolescent delinquent behavior across three ways adoptive families discussed racial and ethnic differences; adolescents whose families acknowledged differences had the fewest mean delinquent behaviors. There were no significant differences in delinquent behavior between adolescents whose families acknowledged or rejected the importance of racial and ethnic differences. However, adopted adolescents whose families held discrepant views of differences had significantly more problem behavior than adolescents whose families either acknowledged or rejected the importance of racial and ethnic differences. Clinicians, adoption professionals, and other parenting specialists should focus on building cohesive family identities about racial and ethnic differences, as discrepant views of differences are associated with the most adoptee delinquent behavior.

    Background. Sexual behaviors and knowledge among PHIV-infected (PHIV(+)) adolescents in comparison with HIV-uninfected youths are not well understood and continue to be studied actively. Objective. To compare sexual behavior and sexual knowledge of PHIV(+) and HIV-uninfected adolescents at an urban, tertiary-care center in New Jersey. Study Design. Modified Centers for Disease Control and Prevention (CDC) Youth Risk Behavior Surveillance questionnaire was administered to PHIV(+) and HIV-uninfected adolescents to assess and compare sexual behavior and knowledge over a 1-year-period. Results. Twenty-seven PHIV(+) and 100 HIV-uninfected adolescents were studied; 59% PHIV(+) and 52% HIV-uninfected adolescents were sexually active. A significantly higher proportion of PHIV(+) adolescents compared to HIV-uninfected adolescents reported ≥1 occasion of unprotected penetrative sex (p 4) sexual partners (p = 0.037). Significantly more PHIV(+) males reported receptive anal intercourse (p sexual abstinence can prevent HIV transmission and >80% adolescents in both groups did not consider multiple sexual partners a risk factor for HIV transmission. Only 25% PHIV(+) adolescents reported disclosing their seropositive status to their first sexual partners. Conclusions. High risk sexual behaviors were significantly more prevalent among PHIV(+) youths; however both groups demonstrated considerable gaps in sexual knowledge. There is an urgent need for heightening awareness about risky behaviors, interventions for prevention, and reproductive health promotion among adolescents.

    Lower family cohesion is associated with adolescent internalizing and externalizing problems. However, there are likely individual differences in youth's responses to family processes. For example, adolescents higher in negative emotional reactivity, who often exhibit elevated physiological responsivity to context, may be differentially affected by family cohesion. We explored whether youth's negative emotional reactivity moderated the relation between family cohesion and youth's symptoms and tested whether findings were consistent with the diathesis-stress model or differential susceptibility hypothesis. Participants were 651 adolescents (M = 12.99 ± .95 years old; 72% male) assessed at two time points (Time 1, ages 12-14; Time 2, age 16) in Pittsburgh, PA. At Time 1, mothers reported on family cohesion and youth reported on their negative emotional reactivity. At Time 2, youth reported on their symptoms. Among youth higher in negative emotional reactivity, lower family cohesion predicted higher symptoms than higher family cohesion, consistent with the diathesis-stress model.

Questionnaire data on psychosocial variables and anthropometric measurements, together with a fasting blood sample, were obtained from 53 low-birthweight and 119 normal-birthweight adolescents. Insulin resistance was calculated using the homeostasis model assessment (HOMA). Spearman correlation analyses showed that both INR (r = 0.244) and hostility (r = 0.204) were significantly (p physical activity and family history of diabetes. The results of the current study show that the positive relationship between INR and metabolic health risk seen in African-Caribbean adults also exists in African Caribbean adolescent youth independent of birthweight.

    Schools are among the most important setting for preventive interventions among adolescents. There are evidence-based intervention programs for adolescents at risk for and with early signs of mental health problems but one demanding task is to detect the ones who are in need of an intervention. The aim of the present study was to analyze associations between self-esteem, depressive symptoms, and social anxiety in order to determine clinically relevant cut-points for male and female adolescents' self-esteem as measured with the Rosenberg Self-Esteem Scale (RSES). The participants of the present prospective study, started in 2002-2003, were 2070 adolescents aged 15 years (1,167 girls and 903 boys) at two study sites in Finland who participated at both baseline and 2-year follow-up. Self-esteem was related to depressive symptoms and social anxiety, and the RSES was able to discriminate between cases of depression and social phobia. The present study suggests a cutoff of 25 points to classify low self-esteem in both girls and boys. Low self-esteem may function as an indicator of various forms of internalizing psychopathology. The RSES is worth further examination as a potential screening tool for adolescents in risk of psychopathology.

    A growing literature supports the importance of understanding the link between religiosity and youths' adjustment and development, but in the absence of rigorous, longitudinal designs, questions remain about the direction of effect and the role of family factors. This paper investigates the bidirectional association between adolescents' relationship with God and their internalizing adjustment. Results from 2-wave, SEM cross-lag analyses of data from 667 mother/adolescent dyads in Belfast, Northern Ireland (50% male, M age = 15.75 years old) supports a risk model suggesting that greater internalizing problems predict a weaker relationship with God 1 year later. Significant moderation analyses suggest that a stronger relationship with God predicted fewer depression and anxiety symptoms for youth whose mothers used more religious coping.

    Full Text Available It was widely accepted that nuclear damage might be extensive and spread to other countries. International civil liability for nuclear damage is embodied by two major instruments: International Atomic Energy Agency (IAEA 1963 Vienna Convention on Civil liability for Nuclear Damage and Paris Convention of 1960 on third party liability (OECD with its amending protocols. Major problem arises because of lack of coherence and for this reason supplementary conventions and protocols has been adopted but sufficient results has not been achieved. International treaties on civil liability for nuclear damage are mostly based upon principles of operator’s exclusive, channeling, strict liability for nuclear damage, mandatory financial coverage, compensation without discrimination. These principles set ground for the appropriate compensation standard thus minimizing the difficulty level of complicated legal cross-actions and identifies certain subjects in individual cases who are liable also allows a concentration of the insurance capacity. Although Conventions sets similar principles, Europe remains in two different liability regimes which cover differences of liability amounts, scope of application, rules of jurisdiction conflicts. Problem of legal coherence at European Union level also arises because Member States are either parties to the Paris Convention or Vienna Convention at different speeds. This research paper provides an in-depth analysis of international legal framework development and impetus to create trans-boundary compensation mechanisms thus to foster development of European Union nuclear energy market and to provide higher protection for victims inside and outside the country where the incident has occurred. Purpose – provide comparative analysis of international treaties which regulate civil liability for nuclear damage in the context of European Union nuclear energy market development.

    A large body of research has examined the development of internalizing and externalizing symptoms in childhood and early adolescence. Notably, there is significant concomitant impairment associated with early adolescent symptomatology, as well as association of these symptoms with future development of psychopathology, poor physical health, self-destructive thoughts and behaviors, criminal behavior, and HIV risk behaviors. Drawing on negative reinforcement theory, the current study sought to examine the potential role of distress tolerance, defined as the ability to persist in goal-directed activity while experiencing emotional distress, as a potential mechanism that may underlie both internalizing and externalizing symptoms among 231 Caucasian and African American youth (M age=10.9 years; 45.5% female; 54.5% Caucasian ethnicity). A series of regressions resulted in significant moderated relationships, such that low distress tolerance conferred increased risk for alcohol use among Caucasians, delinquent behavior among African Americans, and internalizing symptoms among females. Clinical implications, including the potential role of negative reinforcement models in early intervention with young adolescents, are discussed.

    Family violence has been associated with various negative outcomes among children and adolescents. Yet, less is known about how unique forms of physical family violence contribute to externalizing and internalizing behaviors based on a child's developmental stage. Using data from the Illinois Families Study and administrative Child Protective Services data, we explored the relation between 3 types of physical family violence victimization and externalizing and internalizing behaviors among a sample of 2,402 children and adolescents. After including parent and family level covariates in Poisson regressions, we found that a unique form of family violence victimization was associated with increased externalizing behaviors among children at each age group: exposure to physical intimate partner violence (IPV) among children ages 3-5, exposure to the physical abuse of a sibling among children ages 6-12, and child physical abuse among adolescents ages 13-18. No form of physical family violence was significantly associated with internalizing behaviors for children in any age group. Including exposure to the child maltreatment of a sibling is crucial when attempting to contextualize children's responses to family violence and providing comprehensive services in an effort to enhance the well-being of all children in a family.

    Higher self-concept clarity is related to several adjustment indices and may be promoted by open communication with parents, while problems with self-concept clarity development could enhance internalizing problems (i.e., depressive and anxiety symptoms) in adolescence. This longitudinal study examined linkages between self-concept clarity, adolescents' open communication with parents, and adolescent depressive and anxiety symptoms. Dutch youths (N = 323; 51.1 % girls; mean age Time 1 = 13.3 years) reported on these constructs over four consecutive annual measurements. Concurrent positive links between open communication and self-concept clarity were found at Time 1. Over time, higher levels of open communication with parents predicted higher self-concept clarity only in middle adolescence (mean age between 14 and 15 years). We also found concurrent associations between self-concept clarity and both depressive and anxiety symptoms. Longitudinally, lower self-concept clarity predicted relatively higher levels of depressive symptoms across all waves, and also higher anxiety levels from Time 1 to Time 2. Conversely, higher levels of anxiety also predicted lower levels of self-concept clarity during the first three waves. Self-concept clarity did not mediate the longitudinal associations between open communication and internalizing symptoms. This study is one of the first to investigate self-concept clarity across adolescence. It highlights the possible importance of both anxiety symptoms and communication with parents in understanding the development of a clear self-concept, and demonstrates an association between lower self-concept clarity and higher levels of later depressive and anxiety symptoms.

    Full Text Available In both adults and children, metabolic syndrome (MetS has been attributed to risk factors for type 2 diabetes and cardiovascular disease such as insulin resistance, abdominal obesity, hypertension, and dyslipidemia. This descriptive study aimed to compare the prevalence of MetS and diagnostic components according to the National Cholesterol Education Program, Adult Treatment Panel III (NCEP-ATP III and International Diabetes Federation (IDF in 2330 Korean adolescents (10–18 years, using data from the 2010–2012 Korea National Health and Nutrition Examination Survey-V. The NCEP-ATP III and IDF were used to diagnose MetS and yielded prevalence rates of 5.7% and 2.1%, respectively, with no sex-related differences. The most frequent MetS diagnostic components according to the NCEP-ATP III and IDF criteria were high triglyceride levels (21.2% and low high-density lipoprotein cholesterol levels (13.6%, respectively; approximately 50.1% and 33.1% of adolescents had at least one MetS diagnostic component according to the respective criteria. Both overweight/obese male and female adolescents exhibited significantly increased prevalence rates of MetS and related diagnostic components, compared to normal-weight adolescents. In conclusion, the prevalence rates of MetS and diagnostic components differ according to the NCEP-ATP III and IDF criteria. Henceforth, efforts are needed to establish diagnostic criteria for Korean adolescents.

  1. AN INTERNATIONAL COMPARATIVE PERSPECTIVE ON MOTORISATION IN URBAN CHINA

    Directory of Open Access Journals (Sweden)

    2002-01-01

    Full Text Available During a period of economic reform, the People's Republic of China has emerged as an important market for multinational automobile manufacturers and a source of concern for “sustainable transport” advocates worried about the long-term sustainability of systems based on private automobiles and fossil fuels. Much of the growth in China's motor vehicle fleet and the negative consequences of that growth has been concentrated in China's large, economically dynamic coastal cities. Based on a large standardised 1995 database on urban transport, this paper compares characteristics of three of China's largest cities with cities around the world. This international comparative perspective suggests that in 1995, Chinese cities still had exceptionally high use of non-motorised and public transport modes. However, some characteristics of these cities indicated a high potential for extensive and rapid growth in private motor vehicles which could generate significant problems in the future. In particular, the relatively high population density and lack of reserved public transport routes suggested that the potential for highly concentrated negative impacts were in place, while the means of moving large numbers of people with lesser polluting modes of transport than the private motor vehicle were not in place. Finally, data on investment in public transport and freeways indicated that in the early 1990s the conditions were being created for rapid and continued motorisation. While in 1995 China's cities in some ways approximated a “sustainable transport” ideal, this is likely to have already changed substantially.

The aim of this study is to assess alexithymia in anorexic adolescent patients and in their parents using a multimethod measurement to gain more direct, in-depth knowledge of the problem. Methods: Forty-six subjects, anorexic adolescent patients and their parents, underwent the Toronto Alexithymia Scale (TAS-20 along with the Toronto Structured Interview for Alexithymia (TSIA, which represents the first comprehensive clinically structured interview focused specifically on assessing alexithymia. The use of latent trait Rasch analysis allowed a comparison of the two instruments’ sensitivity and ability to detect the presence and intensity of alexithymic components in patients and parents. Results: Significant discordance was found between the two measures. The clinical instrument allowed detection of a greater level of alexithymia compared with the self-report, in particular in our adult parent sample. Moreover, a significant alexithymic gap emerged within families, particularly within parental couples, with noticeably more alexithymic fathers compared with the mothers. Conclusion: The TSIA clinical interview may be a more sensitive instrument in detecting alexithymia, minimizing parents’ negation tendency. Clinical questions have arisen on

    Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8-10) in matched samples of 138 adolescents (34.78 % girls) with low levels of cognitive abilities and 556 adolescents (44.88 % girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within

    This study examined adolescents' attitudes of cosmetic surgery, as well as the relationships between these attitudes, body appreciation, body ideal internalization, and fashion blog reading. The sample comprised 110 (60 boys, 50 girls) late adolescents (mean age 16.9 years) from a Swedish high school. The results indicated that younger adolescents seem somewhat more accepting of cosmetic surgery. This was especially the case for boys' acceptance of social motives for obtaining cosmetic surgery (boys' M=2.3±1.55 vs. girls' M=1.7±0.89). Girls', and to a limited extent boys', internalization of the thin ideal was related to more favorable cosmetic surgery attitudes. Athletic ideal internalization and body appreciation were unrelated to these attitudes. Finally, girls who frequently read fashion blogs reported higher thin ideal internalization, and also demonstrated a slight tendency of more cosmetic surgery consideration.

    Although characteristics of traditional bullying participants have been identified and studied for years, research on cyberbullying is limited. The purpose of this study is to expand the literature on cyberbullying with a particular focus on the relationships among cyberbullying characteristics, typical social activities, and more traditional forms of bullying. The typical activities and experiences with traditional bullying and cyberbullying of 52 children ages 11 to 17 were compared to those of 52 matched controls. Children exposed to cyberbullying, whether as a cyberbully, cybervictim, or both (bully/victim), spent more time on computer-based social activities. Nearly two thirds of cyberbully/victims were also traditional bully/victims. While preliminary, results suggest that efforts to prevent cyberbullying may need to focus on patterns of Internet use, amount and type of social activities, and exposure to traditional bullying as risk factors for engaging in cyberbullying.

  7. Childhood internalizing and externalizing problems predict the onset of clinical panic attacks over adolescence: the TRAILS study.

    Christina M Mathyssek

    Full Text Available BACKGROUND: Panic attacks are a source of individual suffering and are an independent risk factor for later psychopathology. However, much less is known about risk factors for the development of panic attacks, particularly during adolescence when the incidence of panic attacks increases dramatically. We examined whether internalizing and externalizing problems in childhood predict the onset of panic attacks in adolescence. METHOD: This study is part of the TRacking Adolescents' Individual Lives Survey (TRAILS, a Dutch longitudinal population cohort study (N = 1,584. Internalizing and Externalizing Problems were collected using the Youth Self-Report (YSR and the parent-report Child Behavior Checklist (CBCL at baseline (age 10-12. At age 18-20, DSM-IV defined panic attacks since baseline were assessed with the Composite International Diagnostic Interview (CIDI. We investigated whether early adolescent Internalizing and Externalizing Problems predicted panic attacks between ages 10-20 years, using survival analysis in univariate and multivariate models. RESULTS: There were N = 314 (19.8% cases who experienced at least one DSM-IV defined panic attack during adolescence and N = 18 (1.2% who developed panic disorder during adolescence. In univariate analyses, CBCL Total Problems, Internalizing Problems and three of the eight syndrome scales predicted panic attack onset, while on the YSR all broad-band problem scales and each narrow-band syndrome scale predicted panic attack onset. In multivariate analyses, CBCL Social Problems (HR 1.19, p<.05, and YSR Thought Problems (HR 1.15, p<.05 and Social Problems (HR 1.26, p<.01 predicted panic attack onset. CONCLUSION: Risk indicators of panic attack include the wide range of internalizing and externalizing problems. Yet, when adjusted for co-occurring problem behaviors, Social Problems were the most consistent risk factor for panic attack onsets in adolescence.

    Viglione, Donald J; Giromini, Luciano

    2016-01-01

    Currently, there is some debate about whether to use Comprehensive System norms (CS; Exner, 2003 ) or the Composite International Reference Values (CIRV; Meyer, Erdberg, & Shaffer, 2007 ) when interpreting Rorschach Inkblot Method (RIM; Rorschach, 1921 ) protocols administered with the CS method. The goal of this study is to assist clinicians in making this decision by providing information about the effects of choosing one option or the other. Accordingly, this research evaluates the effects of using the CS versus CIRV norms with children, adolescents, and adults. First, we identified 43 variables for which the CS and the CIRV for children and adolescents differ from each other by at least a Cohen's d value of .50. Next, we evaluated whether these divergent variables are the same as those previously identified as divergent for the adult population. Results showed that for both children and adolescents, as well as for adults, relying on CS norms versus CIRV would result in interpretations that are more pathological in terms of (a) perception and thinking, (b) psychological resources and cognitive and emotional abilities, and (c) representations of human relationships. A discussion on the clinical effects of using one versus the other set of norms follows.

    This study investigated frequencies of smoking, alcohol use, and illicit drug use by diagnostic category in 566 adolescent psychiatric patients, comparing this sample with 8173 adolescents from the general population in Norway who completed the Young-HUNT 3 survey. Frequencies of current alcohol use were high in both samples but were lower among psychiatric patients. Compared with adolescents in the general population, adolescents in the clinical sample had a higher prevalence of current smoking and over four times higher odds of having tried illicit drugs. In the clinical sample, those with mood disorders reported the highest frequencies of smoking, alcohol use, and illicit drug use, whereas those with autism spectrum disorders reported the lowest frequencies. Our results show an increased prevalence of risky health behaviors among adolescents with psychiatric disorders compared with the general population. The awareness of disorder-specific patterns of smoking and substance use may guide preventive measures.

    Full Text Available The purpose of the study was to compare the linear kinematics of the barbell and the angular kinematics of the lower limb during the snatch lifts of two different barbell weights in elite male adolescent weightlifters. In the national team level, nine elite male adolescent weightlifters participated in the study. The snatch lifts were recorded by two video cameras under competitive conditions in preparation period before the European Junior Championship (Sony MiniDv PAL- 50 field/s and the two heaviest successful lifts were selected for kinematic analysis. The little toe, ankle, knee, hip, and shoulder on the body and one point on the barbell were digitized using Ariel Performance Analysis System (APAS, San Diego, CA, USA. Significant decreases were found in the maximum barbell height, the relative power output during the second pull, and the maximum vertical velocity of the barbell during the second pull of the heaviest lift (p < 0.05. Maximum extension velocity of the hip joint significantly increased during the first pull of the heaviest lift (p < 0.05. As the mass of the barbell increased, the maximum vertical velocity and the maximum height of the barbell and relative power output during the second pull decreased in the heaviest lift performed by adolescent weightlifters. Coaches should pay attention to assistant exercises to increase explosive strength during the second pull with maximum strength in male adolescent weightlifters.

    Full Text Available OBJECTIVE: We provide a population-based overview of health behaviours of children and adolescents with type 1 diabetes in comparison to the general population, and analyse their relevance for glycaemic control and self-rated health status. METHODS: Data from questionnaires of 11- to 17-year-old children and adolescents with diabetes (n = 629 were compared to a representative sample (n = 6,813. RESULTS: Children and adolescents with type 1 diabetes had a significantly increased odds of infrequent physical activity (adjusted OR 1.56, short overall duration of physical activity per week (OR 1.55, difference -1.3 hours/week, and high daily computer use (OR 2.51. They had a lower odds of active and passive smoking (OR 0.31 and OR 0.29, and high daily television time (OR 0.68. The odds of an at least good and excellent self-rated health status was increased with intense physical activity, and decreased with active smoking and prolonged daily use of computer and television. Active smoking and prolonged daily use of computer were associated with higher HbA1c. CONCLUSIONS: Children and adolescents with type 1 diabetes showed a different profile of health behaviour. Their overall health may improve if their education stresses specifically frequent physical activity with longer overall duration and less frequent television or computer use.

    Full Text Available Background: Adolescents are often less informed, less experienced, and less comfortable accessing reproductive health information and services than adults. In many developing countries, a culture of silence surrounds the topic of menstruation and related issues; as a result many young girls lack appropriate and sufficient information regarding menstrual hygiene. This may result in incorrect and unhealthy behaviour during their menstrual period. Objectives: To assess and compare knowledge, belief, ideas, source of knowledge and practice of menstrual hygiene between school-going adolescents in an urban and a rural school of West Bengal, India. Methods: Cross-sectional, descriptive study was conducted among adolescent female students of Howrah district of West Bengal, India in the year 2011. Data was collected by pre-designed, pre-tested semi-structured self administered questionnaire. Results: The mean age at menarche was 12.1 years among urban and 12.2 years among the rural participants. More than 80% participants had some restrictions imposed during menstruation. Significantly higher number of urban girls had pre-menarchal knowledge on menstruation and used sanitary napkins. Conclusions: Menstrual hygiene is a vital aspect of health education for adolescent girls. For improvement of menstrual hygiene, sanitary napkins should be made universally available and affordable.

    2013-12-01

    This study sought to compare national and international criteria for assessing the nutritional status of adolescents. A cross-sectional analytical study was conducted in the period from July 2007 to January 2008 with a representative sample comprised of 1256 adolescents from the state of Maranhão. Body mass index (BMI) for age and gender was used to diagnose underweight, normal weight and overweight, using the criteria proposed by Conde and Monteiro and the World Health Organization (WHO). Chi-square, McNemar concordance and Spearman correlation tests were applied. According to the criteria of Conde and Monteiro and the WHO, there were significant differences among the boys with respect to low weight and obesity. It was observed that there was no significant divergence between the two criteria, and a significant positive correlation (0.011) between the two criteria was detected. With this analysis it can be seen that there are many divergences between the criteria used, therefore the best option and the advantage of using one or the other cannot be singled out. However, it should be stressed that the national criterion can also be used more, since there are no significant differences with the criteria advocated by the Ministry of Health of the WHO.

    2006-01-01

    Full Text Available In this paper we describe the process used to develop treatment manuals for internalizing and externalizing disorders in children and adolescents. These manuals were developed to offer health care providers and others working in child mental health a flexible intervention that could be adapted to different countries and localities based on: 1 the amount of health care and school resources that are available; 2 the nature and severity of the types of problems children have; and 3 the preferences and cultural factors that are important within these communities. We also discuss the experiences and cultural issues faced by sites in Egypt, Lebanon, Israel, and Brazil who volunteered to implement the manualized treatment programs. The feedback received from these sites indicates that the manuals can be implemented to help children with internalizing and externalizing problems.

  1. Comparative risk assessment: an international comparison of methodologies and results.

    Morgenstern, R D; Shih, J; Sessions, S L

    2000-11-03

    Comparative risk assessment (CRA) is a systematic procedure for evaluating the environmental problems affecting a geographic area. This paper looks beyond the U.S. border and examines the experience with CRAs conducted in various developing countries and economies in transition, including Bangkok, Thailand, Cairo, Egypt and Quito, Ecuador, as well as other locations in Eastern Europe, Asia and Central and South America. A recent pilot CRA conducted in Taiwan is also considered. Comparisons are made of both the methodologies and the results across the relatively diverse international literature. The most robust finding is that conventional air pollutants (e.g., particulate matter and lead) consistently rank as high health risks across all of the CRAs examined. Given the varied nature of the settings studied in the CRAs, including level of economic development, urban-rural differences, and climate, this finding is particularly significant. Problems involving drinking water are also ranked as a high or medium health risk in almost all the countries studied. This is consistent with the results of analyses conducted by the World Bank suggesting contamination, limited coverage and erratic service by water supply systems. Beyond the major air pollutants and drinking water, the CRA results diverge significantly across countries. A number of problems involving toxic chemicals, e. g., hazardous air pollutants, rank as high health risks in the US but do not appear as consistent areas of concerns in the other countries studied. This likely reflects the so-called "risk transition" - the shift from sanitation and infection disease problems to those involving industry, vehicles and toxic substances - that often occurs with economic development. It may also reflect the greater information about sources of toxic pollutants in the U.S. For other problems, there are important differences across the developing countries and economies in transition. For example, hazardous and

    2012-03-01

    Full Text Available Abstract Background The behaviours of non-suicidal self-injury (NSSI and deliberate self-harm (DSH are prevalent among adolescents, and an increase of rates in recent years has been postulated. There is a lack of studies to support this postulation, and comparing prevalence across studies and nations is complicated due to substantial differences in the methodology and nomenclature of existing research. Methods We conducted a systematic review of current (2005 - 2011 empirical studies reporting on the prevalence of NSSI and DSH in adolescent samples across the globe. Results Fifty-two studies fulfilling the inclusion criteria were obtained for analysis. No statistically significant differences were found between NSSI (18.0% SD = 7.3 and DSH (16.1% SD = 11.6 studies. Assessment using single item questions led to lower prevalence rates than assessment with specific behaviour checklists. Mean prevalence rates have not increased in the past five years, suggesting stabilization. Conclusion NSSI and DSH have a comparable prevalence in studies with adolescents from different countries. The field would benefit from adopting a common approach to assessment to aide cross-cultural study and comparisons.

  3. Peremptory Norms in International Law; Development or Revolution of Sources of International Law (A Comparative Analysis of National Legal Systems

    2015-05-01

    Full Text Available Contemporary international law introduces a notion of peremptory norms comparable to hierarchy of norms in national legal system. A jus cogens is a norm of international law considered so fundamental that it overrides all other sources of international law. A rule of jus cogens has a specific process of emergence that will be essentially different from other sources of international law which reflected in Article 38(1 of ICJ Statute. Unfortunately, there is not a precise definition of jus cogens norms. The vagueness of the definition and thereby its instances is one problematic issue that harden realization of ideals of the international community.

    Full Text Available According to Horwitz (1987 learners’ belief about language learning are influenced by previous language learning experiences as well as cultural background. This study examined the English Language Learning Strategies between local and international Chinese students who share the same cultural background but have been exposed to different learning experiences. Given the significant number of local and international Chinese students enrolled in educational institutions, there is a need to understand the differences and similarities in the learning strategies of these two groups. The sample for the study comprised of 60 local and 50 international Chinese students currently enrolled at a local private college. The Oxford Strategy Inventory for Language Learning (SILL was administered as a measure of learning strategy preferences. The study reveals that language learning experiences as well as socioeconomic status impact the learning strategy adopted by both local and international Chinese students. The findings of this study point to the need to address the needs of these students in order to enhance their English language learning experience in Malaysia.

    Recruiting adolescent participants for research is challenging. The purpose of this study was to compare traditional in-person recruitment methods to social media recruitment. We recruited adolescents aged 14-18 years for a pilot physical activity intervention study, including a wearable physical activity tracking device and a Facebook group. Participants were recruited (a) in person from a local high school and an adolescent medicine clinic and (b) through social media, including Facebook targeted ads, sponsored tweets on Twitter, and a blog post. Data collected included total exposure (i.e., reach), engagement (i.e., interaction), and effectiveness. Effectiveness included screening and enrollment for each recruitment method, as well as time and resources spent on each recruitment method. In-person recruitment reached a total of 297 potential participants of which 37 enrolled in the study. Social media recruitment reached a total of 34,272 potential participants of which 8 enrolled in the study. Social media recruitment methods utilized an average of 1.6 hours of staff time and cost an average of $40.99 per participant enrolled, while in-person recruitment methods utilized an average of 0.75 hours of staff time and cost an average of $19.09 per participant enrolled. Social media recruitment reached more potential participants, but the cost per participant enrolled was higher compared to traditional methods. Studies need to consider benefits and downsides of traditional and social media recruitment methods based on study goals and population.

    The aim of this study was to examine the direction and the etiology of the association between different parenting styles (parental emotional overinvolvement [EOI] and parental criticism) and internalizing behavior from adolescence to early adulthood. A longitudinal genetically informative cross-lagged design was applied to a population-based sample of Swedish twins contacted at age 16-17 (n = 2369) and at age 19-20 (n = 1705). Sex-limitation modelling revealed different effects for boys and girls. For girls, genetic influences on internalizing problems at age 16-17 independently explained 2.7% of the heritability in parental EOI at age 19-20. These results suggest that emotionally overinvolved and self-sacrificing parental behavior stems in part from daughters (but not sons) genetic predisposition for internalizing behavior. These findings highlight the importance of genetically influenced child-driven effects underlying the parenting-internalizing association, and clarify that the role of such effects may differ depending on sex, type of parenting and developmental period.

    Full Text Available The present study compared gender differences in parental perceptions of child personality trait expression across different age groups in Slovenia and Russia. The patterns of gender differences in adolescents were further explored using parent and self-rating methods of assessment. Employing the Inventory of Child Individual Differences (Halverson et al., 2003 reports on large samples of children/ adolescents (2 to 15 years in both countries were obtained. Gender differences were small and similar across countries, and their patterns were closer to each other for the same data source across countries than they were for the two sources of information within the country. The parents in both countries concurred in rating daughters as somewhat more achievement orientated, compliant, considerate, and organized, whereas sons were assessed as slightly more active, antagonistic, and distractible. At the higher-order trait level, girls were perceived to be more conscientious and agreeable relative to the boys, especially from middle childhood onwards. Regarding self-reports, adolescent girls also scored significantly higher on Considerate and Positive Emotions scales than boys, while the former reported on higher agreeableness relative to the latter in Slovenia only. Gender differences were evident even in parental assessments of the youngest group but they did not systematically increase over children's age.

    The oil industry is dynamic and global, being performed worldwide and by investors from several countries. In this sense, it is essential for investors to be informed of the legal frameworks in target countries and the differences between the legislation in those countries and their own legal systems. In this article, we will analyze the main differences on the environmental liability in Brazil, which is, currently, one of the most attractive markets in the oil and gas industry, the United States of America (US), the largest consumer of oil and the third producer around the world; and the European Union (EU) which concentrates the second largest global consumer, besides being the main player in the international and diplomatic relationships. Thus, the present paper, without the intent to exhaust the subject matter, aims at presenting comparisons between the legal environment of the three main players in the international oil and gas scenario, specifying not only the legal aspects of each of them, but also outlining the economic impacts generated over business investors from the oil industry, determining that although the differences in the basis of legal framework, all players have presented the liability and the duty to compensate.

  11. Problem partners and parenting: exploring linkages with maternal insecure attachment style and adolescent offspring internalizing disorder.

    Bifulco, Antonia; Moran, Patricia; Jacobs, Catherine; Bunn, Amanda

    2009-01-01

    An intergenerational study examined mothers' insecure attachment style using the Attachment Style Interview (ASI; Bifulco et al., 2002a) in relation to her history of partner relationships, her parenting competence, and depression or anxiety disorder in her offspring. The sample comprised 146 high-risk, mother-adolescent offspring pairs in London, who were recruited on the basis of the mothers' psychosocial vulnerability for depression. Retrospective, biographical, and clinical interviews were undertaken independently with mother and offspring. A path model was developed, which showed that mothers' insecure attachment style had no direct link to either recalled child neglect/abuse or currently assessed disorder in their adolescent and young adult offspring. The connections appeared to be indirect, through the quality of relationships in the family system: mothers' insecure attachment and their partners' problem behavior accounted for variance in mothers' incompetent parenting as rated by interviewers. These variables predicted her neglect/abuse of the child, which was the only variable directly associated with internalizing disorder in her offspring. Mother's lifetime depression did not add to the model. It is argued that an ecological approach (emphasizing social adversity and different role domains) and a lifespan approach (emphasizing a history of adverse relationships a different life stages) is important in understanding the mechanisms by which parental insecure attachment style influences transmission of risk to the next generation.

    Child maltreatment is a robust risk factor for internalizing and externalizing psychopathology in children and adolescents. We examined the role of disruptions in emotion regulation processes as a developmental mechanism linking child maltreatment to the onset of multiple forms of psychopathology in adolescents. Specifically, we examined whether child maltreatment was associated with emotional reactivity and maladaptive cognitive and behavioral responses to distress, including rumination and impulsive behaviors, in two separate samples. We additionally investigated whether each of these components of emotion regulation were associated with internalizing and externalizing psychopathology and mediated the association between child maltreatment and psychopathology. Study 1 included a sample of 167 adolescents recruited based on exposure to physical, sexual, or emotional abuse. Study 2 included a sample of 439 adolescents in a community-based cohort study followed prospectively for 5 years. In both samples, child maltreatment was associated with higher levels of internalizing psychopathology, elevated emotional reactivity, and greater habitual engagement in rumination and impulsive responses to distress. In Study 2, emotional reactivity and maladaptive responses to distress mediated the association between child maltreatment and both internalizing and externalizing psychopathology. These findings provide converging evidence for the role of emotion regulation deficits as a transdiagnostic developmental pathway linking child maltreatment with multiple forms of psychopathology.

    Over half-a-million adolescents take part in each cycle of the Program for International Student Assessment (PISA). Yet often, researchers and policy makers across the globe tend to focus their attention primarily on the academic trajectories of adolescents hailing from highly successful education systems. Hence, a vast majority of the adolescent population who regionally and globally constitute the 'long tail of underachievement' often remain unnoticed and underrepresented in the growing literature on adolescents' academic trajectories. The present study, therefore, explored the relations of dispositions toward mathematics, subjective norms in mathematics, and perceived control of success in mathematics to mathematics work ethic as well as mathematics performance; and the mediational role of mathematics work ethic in the association between dispositional, normative, and control beliefs and mathematics performance among adolescents in one of the lowest performing education systems, Qatar. Structural equation modeling (SEM) analyses revealed that Qatari adolescents' dispositional, normative, and control beliefs about mathematics were significantly associated with their mathematics work ethic and mathematics performance, and mathematics work ethic significantly mediated the relationship between dispositional, normative, and control beliefs about mathematics and mathematics performance. However, multi-group SEM analyses indicated that these relationships were not invariant across the gender and the SES groups.

    Drawing on data from the 2012 Program for International Student Assessment (PISA) and employing multilevel modeling as an analytic strategy, this study examined the relations of adolescent children's perceptions of their parents' attitudes towards mathematics to their own attitudes towards mathematics and mathematics achievement among a sample of 5116 adolescents from 384 schools in the United Arab Emirates. The results of this cross-sectional study revealed that adolescents who perceived that their parents liked mathematics and considered mathematics was important for their children not only to study but also for their career tended to report higher levels of intrinsic and instrumental motivation to learn mathematics, mathematics self-concept and self-efficacy, and mathematics work ethic. Moreover, adolescents who perceived that their parents liked mathematics and considered mathematics was important for their children's career tended to report positive intentions and behaviors toward mathematics. However, adolescents who perceived that their parents considered mathematics was important for their children's career tended to report higher levels of mathematics anxiety. Finally, adolescents who perceived that their parents considered mathematics was important for their children to study performed significantly better on the mathematics assessment than did their peers whose parents disregarded the importance of learning mathematics.

  20. [Adolescence and choice of contraceptive].

    1986-11-01

    The majority of books, studies, and publications on adolescence are written by adults, whose frequent focus on unbridled adolescent sexuality, adolescents in crisis, or immature adolescents does not seem to correspond to the self-image of adolescents. All authors agree that adolescence is the period between childhood and adulthood beginning at puberty, but opinions differ as to the termination of adolescence and entrance into adulthood. The most significant consensus about adolescence is its tendency to become prolonged. The majority of authors regard adolescence as a preparation for adult life and hence as a natural phase necessary and indispensable to human existence. Ethnographic studies of societies that do not acknowledge adolescence demonstrate, however, that it is not a natural phase. It is also evident that comparatively few roles in modern society require lengthy periods of preparation such as adolescence. It is therefore difficult to regard adolescence as a time of preparation for adult life. From a historic perspective, adolescence emerged with the socioeconomic transformations of industrialization. Mechanization and automation excluded numerous types of workers, especially young workers, from the labor force. Adolescence represents marginalization of young people in response to socioeconomic exigencies rather than a period of preparation for a better adult life. The marginalization is internalized in the consciousness of adults and youth alike and in their hierarchical relations. The marginalization of young people is expressed in the domain of sexuality by the fact that, although physiologically mature, adolescents are not viewed as psychologically mature enough to have children. Adolescents have sexual relations at increasingly young ages, but unlike adults they are not permitted by society the choice of having a child. Contraception, an option for adults, becomes obligatory for sexually active adolescents. The refusal of contraception or failure to

    Full Text Available This study uses a large and representative sample of adolescents to test the theoretically informed hypotheses comparing adolescent singletons with those who have siblings. The results found that, for academic related outcomes (educational expectations, time spent on homework, and self-reported grades, there are no differences between singletons and firstborns who have any number of younger siblings. Singletons are also not different from laterborns from two-child families. In contrast, singletons are more advantageous compared to laterborns who have two or more siblings on educational expectations and grades. Singletons also spend more time on homework than laterborns who have three or more siblings. For psychosocial outcomes (psychological distress, susceptibility to negative peer pressure, and problem behaviors, singletons are not different from both firstborns and laterborns with any number of siblings. The findings suggest that singletons are not at any disadvantage compared to their peers who have siblings and they enjoy some advantages over laterborns from medium to large families on academic related outcomes.

  4. Smoothing internal migration age profiles for comparative research

    Aude Bernard

    2015-05-01

    Full Text Available Background: Age patterns are a key dimension to compare migration between countries and over time. Comparative metrics can be reliably computed only if data capture the underlying age distribution of migration. Model schedules, the prevailing smoothing method, fit a composite exponential function, but are sensitive to function selection and initial parameter setting. Although non-parametric alternatives exist, their performance is yet to be established. Objective: We compare cubic splines and kernel regressions against model schedules by assessingwhich method provides an accurate representation of the age profile and best performs on metrics for comparing aggregate age patterns. Methods: We use full population microdata for Chile to perform 1,000 Monte-Carlo simulations for nine sample sizes and two spatial scales. We use residual and graphic analysis to assess model performance on the age and intensity at which migration peaks and the evolution of migration age patterns. Results: Model schedules generate a better fit when (1 the expected distribution of the age profile is known a priori, (2 the pre-determined shape of the model schedule adequately describes the true age distribution, and (3 the component curves and initial parameter values can be correctly set. When any of these conditions is not met, kernel regressions and cubic splines offer more reliable alternatives. Conclusions: Smoothing models should be selected according to research aims, age profile characteristics, and sample size. Kernel regressions and cubic splines enable a precise representation of aggregate migration age profiles for most sample sizes, without requiring parameter setting or imposing a pre-determined distribution, and therefore facilitate objective comparison.

    2015-01-01

    We examined evidence that peer victimization in middle childhood is a lead indicator of internalizing behavior problems and diagnostic outcomes during adolescence. This research was conducted as part of an ongoing multisite longitudinal investigation. The participants were 388 children (198 boys, 190 girls). Peer victimization was assessed with a peer nomination inventory that was administered when the average age of the participants was approximately 8.5 years. Internalizing problems were assessed using a behavior problem checklist completed by mothers in 9 consecutive years, and a structured clinical interview was administered to the participants in the summer following high school graduation (10-11 years after the victimization assessment). Peer victimization in middle childhood was correlated with internalizing problems on a bivariate basis through the late years of adolescence. Multilevel analyses also revealed associations between peer victimization and increases in internalizing problems over time. In addition, peer victimization had a modest link to unipolar depressive disorders in late adolescence. Victimization in the peer group during middle childhood appears to be a marker of long-term risk for internalizing behavior problems and unipolar depression.

    The current study tested the associations between peer victimization and internalizing symptoms in 54 verbally fluent adolescent males with a diagnosis of autism spectrum disorder. Adolescent- and parent-reports of multiple types of peer victimization and internalizing symptoms were used. First, the validity and reliability of the adolescent-report measure of peer victimization were successfully tested, with some exceptions. Then, structural equation models showed that adolescent-reports of peer victimization were associated with a latent construct of internalizing symptoms even after controlling for parent-reports of peer victimization. Discussion focuses on the importance of considering adolescent-reports of negative peer experience, such as peer victimization, rather than relying exclusively on parent reports.

    The purposes of the present study were to: (1) describe rates of peer victimization in young adolescents with attention-deficit/hyperactivity disorder, (2) evaluate the association between types of peer victimization (i.e., physical, relational, and reputational) and internalizing problems (i.e., anxiety, depression, and self-esteem), and (3) examine whether associations between victimization and internalizing problems differ for males or females. Participants were 131 middle-school students (ages 11-15 years, 73 % male, 76 % White) diagnosed with ADHD who completed ratings of victimization, anxiety, depression, and self-esteem. Over half of the participants (57 %) reported experiencing at least one victimization behavior at a rate of once per week or more, with higher rates of relational victimization (51 %) than reputational victimization (17 %) or physical victimization (14 %). Males reported experiencing more physical victimization than females, but males and females did not differ in rates of relational or reputational victimization. Whereas relational and physical victimization were both uniquely associated with greater anxiety for both males and females, relational victimization was associated with greater depressive symptoms and lower self-esteem for males but not females. These findings indicate that young adolescents with ADHD frequently experience peer victimization and that the association between victimization and internalizing problems among young adolescents with ADHD differs as a result of victimization type, internalizing domain, and sex.

    Background Literature has demonstrated the adaptive function of identity development and parenting toward manifestation of problem behaviors in adolescence. These dimensions act on both internalizing and externalizing symptoms. Methods The objective is to investigate the relationship between identity status, parenting, and adolescent problems, which may manifest through internalized (phobias, obsessions, depression, eating disorders, entropy) and externalized modes (alcohol use and school discomfort). The research involved 198 Italian students (104 males and 94 females) in the 4th year (mean =16.94 years, standard deviation =0.35) and 5th year (mean =17.94 years, standard deviation =0.43) of senior secondary schools, who live in Caltanissetta, a town located in Sicily, Italy. The research lasted for 1 school year. The general group consisted of 225 students with a mortality rate of 12%. They completed an anamnestic questionnaire to provide 1) basic information, 2) alcohol consumption attitude in the past 30 days, and 3) their beliefs about alcohol; the “Ego Identity Process Questionnaire” to investigate identity development; the “Parental Bonding Instrument” to measure the perception of parenting during childhood; and the “Constraints of Mind” to value the presence of internalizing symptoms. Results Data show that identity status influences alcohol consumption. Low-profile identity and excessive maternal control affect the relational dependence and the tendency to perfectionism in adolescents. Among the predictors of alcohol use, there are socioeconomic status, parental control, and the presence of internalizing symptoms. Conclusion Family is the favored context of learning beliefs, patterns, and values that affect the broader regulatory social environment, and for this reason, it is considered the privileged context on which to intervene to reduce the adolescents’ behavior problems. This deviance could be an external manifestation of the difficulty

    Full Text Available Objectives: Poor motor skills are associated with a range of psychosocial consequences, including internalizing (anxious and depressive symptoms. The Elaborated Environmental Stress Hypothesis provides a causal framework to explain this association. The framework posits that motor skills impact internalizing problems through an indirect effect via perceived social support. However, empirical evaluation is required. We examined whether motor skills has an indirect effect on anxious and depressive symptoms via perceived family support domains. Methods: This study used a community sample of 93 adolescents (12-16 years. Participants completed measures of motor skills, perceived social support across three dimensions (family, friend, and significant other, depressive symptoms, and anxious symptoms. Age, gender, verbal IQ, and ADHD symptoms were included as control variables.Results: Regression analysis using PROCESS revealed that motor skills had an indirect effect on depressive symptoms via perceived family support, but not by perceived friend support or significant other support. The negative association between motor skills and anxious symptoms was not mediated by any perceived social support domain. Conclusions: Findings are consistent with previous literature indicating an association between motor skills and internalizing problems. However, we identified a different pattern of relationships across anxious and depressive symptoms. While anxiety and depressive symptoms were highly correlated, motor skills had an indirect effect on depressive symptoms via perceived family support only. Our findings highlight the importance of family support as a potential protective factor in the onset of depressive symptoms. This study provides partial support for the Elaborated Environmental Stress Hypothesis, however further research is required.

    The International Conference on Population and Development in Cairo in 1994 laid out a bold, clear, and comprehensive definition of reproductive health and called for nations to meet the educational and service needs of adolescents to enable them to deal in a positive and responsible way with their sexuality. In the context of the ongoing review of the International Conference on Population and Development Programme of Action and the considerations for a post-2015 development agenda, this article summarizes the findings of the articles presented in this volume and identifies key challenges and critical answers that need to be tackled in addressing adolescent sexual and reproductive health and rights. The key recommendations are to link the provision of sexuality education and sexual and reproductive health (SRH) services; build awareness, acceptance, and support for youth-friendly SRH education and services; address gender inequality in terms of beliefs, attitudes, and norms; and target the early adolescent period (10-14 years). The many knowledge gaps, however, point to the pressing need for further research on how to best design effective adolescent SRH intervention packages and how best to deliver them.

    Used standardized questionnaires to compare psychosocial functioning of 116 children and adolescents (9 to 18 years) and 73 adults (18 to 38 years) operated on for hypospadias, a congenital penile anomaly, with that of 88 and 50 age-matched comparison males, respectively, treated for an inguinal hernia. The relationships of coping with penile appearance, subject age, severity of hypospadias, number of operations, age at final surgery, and type of surgical procedure with psychosocial functioning were also investigated. Hypospadias patients did not exhibit a poorer psychosocial functioning and no significant relationships of various medical characteristics with psychosocial functioning could be discerned. Genital/body perception of hypospadias patients ages 9 to 18 years correlated positively with psychosocial functioning, albeit with low values. These findings are important for psychologists and specialists in the counseling process of hypospadias patients and their parents.

    Full Text Available EnglishCompared to older, more educated mothers, adolescent mothers are more prone to less than optimal parenting interactions with their children. Moreover, adolescents' children are more likely to experience developmental challenges. In this study, effects of social-environmental factors in the first two years of life on children's anxiety and hyperactivity from age 2 to 8 were examined by analyzing Canadian longitudinal data. Initial levels of anxiety and hyperactivity were higher for children of adolescent mothers, and anxiety increased with age for all children. Female children displayed lower initial levels of hyperactivity than males, and females of adolescent mothers showed a steeper decrease in hyperactivity while males of adolescent mothers showed a steeper increase in hyperactivity than their counterparts parented by older mothers. Parenting,social support and other demographic factors were controlled for and the effects of these predictor variables on trajectories of anxiety and hyperactivity are discussed.FrenchEn comparaison aux mères plus âgées et ayant reçu une meilleure éducation, lesmères adolescentes ont tendance à avoir des interactions parentales moinsqu’idéales.

    The aim of the study was to investigate mental health and resilience in adolescents who have been internationally adopted and their non-adopted peers and examine the potential interaction between adoption status and resilience on mental health problems. Data from the population based youth@hordaland-survey, conducted in Hordaland County, Norway, in 2012 was used. In all, 10 257 adolescents aged 16-19 years provided self-reported data on several mental health instruments. Of these, 45 adolescents were identified as internationally adopted. Adoptees reported more symptoms of depression, attention-deficit/hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD) and perfectionism than non-adopted adolescents, but there were no differences regarding resilience. Adolescents with higher resilience scores reported fewer symptoms of mental health problems, however, no interaction effects were found for adoption status and total resilience score on measures of mental health problems. Our findings indicate that knowledge of resilience factors can form the basis for preventive interventions.

    The 10th revision of the classification of mental disorders and behavioural disorders is due to description of clinical symptoms and diagnostic criteria more accurate and enriches the activities of departments of child and adolescent psychiatry. Diagnostics, therapy and prevention profit not only from sections dealing with newly conceived disorders which begin in childhood and adolescence but also other sections where problems relating to children and adolescents are pointed out. The Czech translation inovates clinical pictures given in our textbook of Child psychiatry published in 1963 and thus replaces partly a hitherto not published modern Czech textbook of child and adolescent psychiatry.

    The relationship of parenting styles with adolescents' outcomes was analyzed within a sample of Spanish adolescents. A sample of 1456 teenagers from 13 to 16 years of age, of whom 54.3% were females, reported on their parents' child-rearing practices. The teenagers' parents were classified into one of four groups (authoritative, authoritarian, indulgent, or neglectful). The adolescents were then contrasted on two different outcomes: (1) priority given to Schwartz's self-transcendence (universalism and benevolence) and conservation (security, conformity, and tradition) values and (2) level of self-esteem (appraised in five domains: academic, social, emotional, family and physical). The results show that Spanish adolescents from indulgent households have the same or better outcomes than adolescents from authoritative homes. Parenting is related with two self-esteem dimensions--academic and family--and with all the self-transcendence and conservation values. Adolescents of indulgent parents show highest scores in self-esteem whereas adolescents from authoritarian parents obtain the worst results. In contrast, there were no differences between the priority given by adolescents of authoritative and indulgent parents to any of the self-transcendence and conservation values, whereas adolescents of authoritarian and neglectful parents, in general, assign the lowest priority to all of these values.

    Using the Adolescent Coping Scale, ACS (Frydenberg & Lewis, 1993) we surveyed 45 randomly selected foreign adolescents in Australian schools. The coping strategies used most by the participants were: focus on solving the problem; seeking relaxing diversions; focusing on the positive; seeking social support; worry; seeking to belong; investing in close friends; wishful thinking; and keep to self (Table 4). With regard to coping styles, the most widely used was the productive coping followed by non-productive coping while the least used style was reference to others (Table 4). In terms of both genders the four coping strategies used most often were:  work hard to achieve; seeking relaxing diversions; focus on solving the problem; and focus on the positive (Table 5). The most noticeable gender difference was the use of the physical recreation coping strategy in which male students engaged more (Fig 1). The usage of four coping strategies (solving problem; work hard; focus on positive; and social support) was higher for students who have been away from family more than once as compared to those who have been away once only while the usage of seeking relaxing diversions was higher for the first timers (Table 6). No significant differences were obtained on the sample's performance on the ACS subscales by gender (Table 7), frequency of leaving own country (Table 8), country of origin (Table 9), and length of stay in Australia (Table 11). However, foundation students scored significantly higher on the reference to others variable than their secondary school peers (Table 10). We recommended counseling for students with high support needs and further large-scale mixed-methods research to gain additional insights.

    This research examined how adolescents' internalizing symptoms, such as depression, anxiety, and loneliness, relate to the content of their Facebook communication and the responses they receive from peers on Facebook. Participants (n = 125, 56 female, age 18) reported on their internalizing symptoms in the summer following 12(th) grade, and downloaded an application to their Facebook account that stored the content of all of their Facebook communication to secure, online archive. Two months of participants' status updates and comments and peers' comments were coded for content. Relations between internalizing symptoms and Facebook communication differed for girls and boys. For girls, internalizing symptoms predicted several types of Facebook content: negative affect, somatic complaints and eliciting support. In contrast, internalizing symptoms were not related to boys' Facebook posts. Relations between internalizing symptoms and peers' responses on Facebook also differed by gender. For girls, internalizing symptoms positively predicted receiving more peer comments expressing negative affect, and peer responses offering support. For boys, internalizing symptoms did not predict any of the measured peer responses. These findings suggest that girls prone to internalizing symptoms use Facebook in ways that appear similar to co-rumination, by expressing problems to friends and receive possibly reinforcing feedback in return.

    There is no consensus in the literature concerning the optimal approach for performing a fluoroscopically guided shoulder arthrogram injection in a pediatric population. To compare adequacy of capsular injection and radiation doses between fluoroscopically guided anterior and posterior glenohumeral joint contrast injections in adolescents. We evaluated imaging in 67 adolescents (39 boys, 28 girls; mean age 16.0 years; range 11.7-19.1 years) who underwent an anterior approach glenohumeral contrast injection with subsequent MR imaging, and 67 age- and gender-matched subjects (39 boys, 28 girls; mean age 16.0 years; range 11.1-19.2 years) who underwent a posterior approach injection during the period June 2010 to September 2015. Two pediatric radiologists independently evaluated all MR shoulder arthrograms to assess adequacy of capsular distention and degree of contrast extravasation. We recorded total fluoroscopic time, dose-area product (DAP) and cumulative air kerma (CAK). There were no significant differences in age, gender, height, weight or body mass index between the populations (P-values > 0.6). The amount of contrast extravasation between the groups was not significantly different (P = 0.27). Three anterior injections (4.5%) and one posterior (1.5%) were suboptimal (P = 0.62). Fluoroscopy time was not different: 1.1 min anterior and 1.3 min posterior (P = 0.14). There was a significant difference in CAK (0.7 mGy anterior and 1.1 mGy posterior; P = 0.007) and DAP (5.3 μGym{sup 2} anterior and 9.4 μGym{sup 2} posterior; P = 0.008). Inter-rater agreement was excellent (Cohen kappa >0.81). Both techniques were technically successful. There was no difference in the fluoroscopy time for either approach. The radiation dose was higher with the posterior approach but this is of questionable clinical significance. (orig.)

    Full Text Available Background: Dietary polyamines have been shown to give a significant contribution to the body pool of polyamines. Knowing the levels of polyamines (putrescine, spermidine, and spermine in different foods and the contribution of daily food choice to polyamine intake is of interest, due to the association of these bioactive amines to health and disease. Objective: To estimate polyamine intake and food contribution to this intake in adolescents compared to a diet fulfilling the Swedish Nutrition Recommendations. Design: A cross-sectional study of dietary intake in adolescents and an ‘ideal diet’ (Swedish nutrition recommendations objectified [SNO] list of foods was used to compute polyamine intake using a database of polyamine contents of foods. For polyamine intake estimation, 7-day weighed food records collected from 93 adolescents were entered into dietetic software (Dietist XP including data on polyamine contents of foods. The content of polyamines in foods recommended according to SNO was entered in the same way. Results: The adolescents’ mean daily polyamine intake was 316±170 µmol/day, while the calculated contribution according to SNO was considerably higher with an average polyamine intake of 541 µmol/day. In both adolescent's intake and SNO, fruits contributed to almost half of the total polyamine intake. The reason why the intake among the adolescents was lower than the one calculated from SNO was mainly due to the low vegetable consumption in the adolescents group. Conclusions: The average daily total polyamine intake was similar to that previously reported in Europe. With an ‘ideal’ diet according to Swedish nutrition recommendations, the intake of this bioactive non-nutrient would be higher than that reported by our adolescents and also higher than that previously reported from Europe.

    The international Headache Society (I H S) diagnostic criteria (International classification of headache disorders edition 2- ICHD 2) for headache in children and adults improved the accuracy of migraine diagnoses. However many short duration headaches in children, receive an atypical migraine diagnosis. This study is to diagnose children and adolescents who presented with such atypical migraines of less than one hour duration. 1402 children and adolescents aged 5 to 15 years who presented with recurrent brief activity affected head pain, were studied. Known and common migraine triggers and family history of migraine were recorded in all. All the children studied had moderate to severe headache lasting 5 to 45 minutes which forced them motionless during the attacks (thus fulfilling 2 diagnostic pain features). At least one of the ICHD2 pediatric migraine diagnostic symptoms (nausea / vomiting / photophobia / phonophobia) were present in all. Two additional features were diagnostic of brief migraines in all of them- one of the parents or siblings was a migrainer and one of the common migraine triggers as a precipitating factor. This study concludes that if duration of head pain is less than one hour ,two additional features to be included to diagnose definitive migraine in children and adolescents - one migraine parent or sibling and one of the migraine triggers precipitating the head pain.

In doing so, a critique of the international transfer of globally dominant research modalities and strategies is presented--along with arguments for increased attention to context sensitivity in both international development cooperation and educational research in general. Illustrative examples that support these arguments are drawn from the author's own research, from an analysis of emergent educational policy debates in the UK, and from related studies being carried out in Malaysia. In concluding, the strategic role of comparative research traditions and perspectives in a rapidly globalizing world is highlighted, while supporting the promotion of new initiative and research centres for comparative and international education.

    Full Text Available Abstract Background This study aimed to clarify associations between pain, psychological adjustment, and family functioning with health-related quality of life (HRQOL in a sample of adolescents with sickle cell disease (SCD utilizing teen- and parent-report. Methods Forty-two adolescents (between the ages of 12 and 18 with SCD and their primary caregivers completed paper-and-pencil measures of pain, teen's psychological adjustment, and HRQOL. In addition, primary caregivers completed a measure of disease-related parenting stress. Medical file review established disease severity. Results Pearson correlations identified significant inverse associations of pain frequency with physical and psychosocial domains of HRQOL as rated by the teen and primary caregiver. Generally, internalizing symptoms (i.e. anxiety and depression and disease-related parenting stress were also significantly correlated with lower HRQOL. Examination of possible mediator models via a series of regression analyses confirmed that disease-related parenting stress served as a mediator between pain frequency and physical and psychosocial HRQOL. Less consistent were findings for mediation models involving internalizing symptoms. For these, parent-rated teen depression and teen anxiety served as mediators of the association of pain frequency and HRQOL. Conclusion Results are consistent with extant literature that suggests the association of pain and HRQOL and identify concomitant pain variables of internalizing symptoms and family variables as mediators. Efforts to improve HRQOL should aim to address internalizing symptoms associated with pain as well as parenting stress in the context of SCD management.

    A sample of 15-year-olds in India took part in the Program for International Student Assessment (PISA) for the first time in 2010. The PISA reading, mathematics, and science literacy scores of Indian adolescents were considerably lower than their counterparts in most PISA participating countries. In order to explore potential reasons for this, the present study, therefore, drawing on data from the fourth cycle of PISA and employing multilevel modeling, examined the relations of student- and school-level factors to reading, mathematics, and science literacy among 4826 15-year-old students from 213 schools in India. Gender, metacognitive learning strategies, students' positive attitudes toward school, and students' positive perceptions of classroom climate were found to be significantly associated with Indian adolescents' performance on the PISA assessment.

    2016-06-01

    Peer relations constitute a main developmental context for adolescents. Peers offer an instance for identity definition and set the norms of acceptable and valued characteristics, behaviors, and attitudes, representing a societal model that allows and restrains avenues for adolescents' socioemotional development. The present article departs from these considerations to review research on adolescents' peer relations in Latin America from a socioemotional perspective. First, approaches to adolescence are discussed, with a main focus on attachment and identity theories, based on a bioecological framework. Then, a review of research in Latin America on friendships, school climate, and intergroup relations is presented. The discussion addresses the tension between theories and evidence generated in developed societies and highlights the particularities of Latin American youth, stressing the need for collecting local data.

    Given the rise in depression disorders in adolescence, it is important to develop and study depression prevention programs for this age group. The current study examined the efficacy of Interpersonal Psychotherapy-Adolescent Skills Training (IPT-AST), a group prevention program for adolescent depression, in comparison to group programs that are typically delivered in school settings. In this indicated prevention trial, 186 adolescents with elevated depression symptoms were randomized to receive IPT-AST delivered by research staff or group counseling (GC) delivered by school counselors. Hierarchical linear modeling examined differences in rates of change in depressive symptoms and overall functioning from baseline to the 6-month follow-up assessment. Cox regression compared rates of depression diagnoses. Adolescents in IPT-AST showed significantly greater improvements in self-reported depressive symptoms and evaluator-rated overall functioning than GC adolescents from baseline to the 6-month follow-up. However, there were no significant differences between the two conditions in onset of depression diagnoses. Although both intervention conditions demonstrated significant improvements in depressive symptoms and overall functioning, results indicate that IPT-AST has modest benefits over groups run by school counselors which were matched on frequency and duration of sessions. In particular, IPT-AST outperformed GC in reduction of depressive symptoms and improvements in overall functioning. These findings point to the clinical utility of this depression prevention program, at least in the short-term. Additional follow-up is needed to determine the long-term effects of IPT-AST, relative to GC, particularly in preventing depression onset.

    Full Text Available In this study, the internationalism strategies and policies of Turkish higher education institutions and their reflections has been compared with the way in which the higher education institutions practise in the United Kingdom. This study has been conducted with regard to the foreign students enrolled on the Turkish programmes, the position of the universities at the international rankings (Times Higher Education Rankings and the number of the international academic staff in Turkish universities. The results showed that although Turkish universities and Turkish Council of Higher Education have not completed their process of making a compatible internationalism policy, especially the internationalism strategies of the foundation universities have been more successful and these universities have showed much better results in the rankings by means of their successful internationalism strategies and policies. Nevertheless, it is not necessarily true that the internationalism strategies in the non-profit universities are very healthy due to the fact that the state universities showed great success in recruiting more international students.

    Salaam, Braima; Mounts, Nina S

    2016-06-01

    This investigation addressed the relation between maternal warmth, behavioral control, psychological control, and psychological adjustment in a sample of 119 Ghanaian adolescents (42% boys) living in an urban area (mean age = 14.19). Adolescents in the sample reported clinically elevated levels of depression and anxiety. Significant associations were found between warmth, behavioral control, and psychological control and adolescents' anxiety, physical aggression, relational aggression, positive friendship quality, and conflict with friends. Warmth moderated the effect of behavioral control on anxiety, physical aggression, and relational aggression such that higher levels of warmth in combination with higher levels of behavioral control were related to more positive adjustment. Higher levels of warmth in conjunction with higher psychological control were related to higher levels of anxiety. Boys who reported lower levels of warmth in combination with higher behavioral control reported higher levels of physical aggression. For boys reporting higher levels of warmth, higher behavioral control was associated with lower physical aggression.

    Adolescent internalizing and externalizing psychopathology is strongly associated with adult psychiatric morbidity, including psychotic disorders. This study examined whether internalizing or externalizing trajectories (continuity/discontinuity of symptoms) from middle childhood were associated with adolescent psychotic-like experiences (PLEs). Prospective data were collected from a community sample of 553 children (mean age = 10.4 years; 50% male) and their primary caregivers. Participants completed questionnaire reports of internalizing and externalizing psychopathology and PLEs at baseline, and again approximately 2 years later. Logistic regression was used to examine the association of adolescent PLEs with four trajectories of internalizing and externalizing psychopathology (persistent, incident, remitting, and none), controlling for a range of potential confounders and sampling bias. Significant associations were identified between adolescent PLEs and the incident internalizing (adjusted odds ratio [adj. OR] = 2.96; 95% confidence interval [CI] = 1.60-5.49) and externalizing psychopathology (adj. OR = 2.14; 95% CI = 1.11-4.14) trajectories, as well as the persistent internalizing (adj. OR = 1.90; 95% CI = 1.13-3.18) and externalizing (adj. OR = 1.81, 95% CI = 1.02-3.19) trajectories. Children with remitting psychopathology trajectories were no more likely to present later PLEs than those who never experienced psychopathology. While for many individuals symptoms and illness remit during development without intervention, this study provides important insights regarding potential targets and timing for delivery of early intervention and prevention programs.

    2010-10-01

    While physical activity is beneficial for youth with developmental disabilities, little is known about those individuals' fitness profile and levels of activity. Therefore the purpose of this study was to investigate the physical fitness profile and physical activity level of 30 adolescents with and without Asperger syndrome (AS). Evaluations were done using the Eurofit physical fitness test and the Baecke Habitual Physical Activity questionnaire. A 2 x 2 MANOVA indicated that adolescents with AS scored significantly lower than the comparison group on all physical fitness subtests, including balance, coordination, flexibility, muscular strength, running speed, and cardio-respiratory endurance (p < .001). Adolescents with AS were also less physically active (p < .001). Engagement in physical activities is therefore recommended.

  18. Neuroticism and Conscientiousness as Moderators of the Relation Between Social Withdrawal and Internalizing Problems in Adolescence.

    Smith, Kelly A; Barstead, Matthew G; Rubin, Kenneth H

    2017-04-01

    Social withdrawal, or refraining from social interaction in the presence of peers, places adolescents at risk of developing emotional problems like anxiety and depression. The personality traits of neuroticism and conscientiousness also relate to emotional difficulties. For example, high conscientiousness predicts lower incidence of anxiety disorders and depression, while high neuroticism relates to greater likelihood of these problems. Based on these associations, socially withdrawn adolescents high in conscientiousness or low in neuroticism were expected to have lower levels of anxiety and depressive symptoms. Participants included 103 adolescents (59 % female) who reported on their personality traits in 8th grade and their anxiety and depressive symptoms in 9th grade. Peer ratings of social withdrawal were collected within schools in 8th grade. A structural equation model revealed that 8th grade withdrawal positively predicted 9th grade anxiety and depressive symptoms controlling for 8th grade anxiety and depressive symptoms, but neuroticism did not. Conscientiousness moderated the relation of withdrawal with depressive symptoms but not anxiety, such that high levels of conscientiousness attenuated the association between withdrawal and depressive symptoms. This buffering effect may stem from the conceptual relation between conscientiousness and self-regulation. Conscientiousness did not, however, moderate the association between withdrawal and anxiety, which may be partly due to the role anxiety plays in driving withdrawal. Thus, a conscientious, well-regulated personality partially protects withdrawn adolescents from the increased risk of emotional difficulties.

    Full Text Available The relationship between international trade and growth is one of the most popular debates in international economics literature. Although there are numerous theoretical approaches and empirical studies about the issue, the direction of the causality and the magnitude of the interaction still remain unclear. In this study, qualitative comparative analysis introduced by Ragin (1987 is applied, different from the previous empirical studies on the topic. The results present the conditions for growth in the country groups involved. The findings imply that trade policy is still of great importance in terms of stimulating growth in developing countries, while it has little importance in developed countries.

Methods: A cross-sectional study based on secondary analysis of data from a representative sample of high school students in Pernambuco (n = 4,207, 14 - 19 years was conducted. Data were collected through a previously validated questionnaire. Adolescents who reported a daily consumption of soft drinks and occasional consumption of fruits, juices and vegetables were classified as exposed to inadequate standard of consumption of these foods. The independent variable was the place of residence (urban/rural. Data were analyzed by frequency distribution, χ2 test and binary logistic regression. Results: It was observed that students residing in rural areas had a higher prevalence of occasional consumption of natural fruit juices (37.6%; 95%CI 36.1 - 39.0 than those living in urban areas (32.1%; 95%CI 30.7 - 33.6. The proportion of students exposed to daily consumption of soft drinks was higher among those who reported they lived in urban areas (65.0%; 95%CI 63.5 - 66.4 compared to those who reported living in rural areas (55.3%; 95%CI 53.8 - 56.9. Conclusion: Adolescent students living in rural areas had a higher prevalence of low consumption of natural fruit juices while those residing in urban areas had a higher prevalence of daily consumption of soda drinks.

Another objective is to highlight the most effective method of treatment in terms of overall rehabilitation period, the time spent by the patient in the rehabilitation centre and the preservation of scoliosis correction. 9 adolescents patients (aged between 14 and 17 years with idiopathic scoliosis were divided into three groups based on the followed kinetic method. Three patients underwent a physical therapy program based on the conventional Klapp and Cotrel method, three patients performed Schroth method, and the other three patients performed Vojta method. All patients were monitored for 6 months. They followed a certain rehabilitation therapy in a specialized centre under the guidance of specialized therapist. Height, weight and scoliosis curvature (measured by the Cobb angle were assessed at the beginning of the program and after 6 months of kinetic program. The small number of patients in each group could not issue conclusions regarding the statistical efficiency of the three methods of therapy. However, besides the conventional therapy, both Schroth method and Vojta method represent possibilities to treat the adolescent patients with idiopathic scoliosis.

    Background Evidence in the literature suggests that there is an impairment of social cognition in schizophrenia. Theory of Mind (ToM) is defined as one’s ability to understand others’ wishes, beliefs, intentions, and other psychological states and thereby to judge others’ behavior, as an essential component of social cognition. However, there have been limited studies on social cognition, especially ToM in adolescent onset schizophrenia (AOS). The current study aims to investigate ToM abilities in adolescent schizophrenia according to various ToM subcomponents (cognitive ToM and affective ToM) and various ToM orders (first order and second order). Methods This study examines ToM in 35 adolescent schizophrenic patients and 35 healthy adolescents using the “Yoni task” and “Faux Pas Recognition test” to assess their affective and cognitive ToM abilities. Results In the Yoni task, patients with AOS showed differences in ToM abilities either on a different order or under different conditions. The Faux Pas Recognition task results revealed that AOS patients were not always able to recognize a faux pas or understand complicated emotions under the faux pas scenario. Furthermore, as indicated by the correlation analysis, neither cognitive ToM nor affective ToM was related to the patients’ symptoms, disease duration, dose of medication, or intelligence quotient (IQ). Conclusion Our findings showed AOS impairment in the performance of ToM tasks. It seemed that impairment in second-order-ToM is more serious. Moreover, these deficits are largely independent of symptom clusters, disease duration, dose of medication, and IQ. It can be speculated that ToM dysfunction may be a hallmark of adolescent schizophrenia.

Results: The results show significant differrences in self-esteem between D/HH and HA adolescents. D/HH adolescents have, on average, lower self-esteem than HA. There are differences in self-esteem regarding gender and also regarding ages of 16 and of 20. D/HH adolescents who use speech or sign language in their communication have higher self-esteem than those who use mostly sign language. D/HH adolescents in mainstream schools have higher self-esteem than those included into a segregated form of schooling. Discussion: There are differences among adolescents in how they view themselves. Self-esteem can be a significant predictor of life satisfaction. Conclusion: D/HH adolescents experience lower self-esteem when compared with HA peers.

    With increasing frequency of Internet use among adolescents, there are growing concerns about their risk for becoming attached to these forms of communication and increased vulnerability for negative online experiences, including cyber victimization. The effect of these experiences on adolescent mental health is not well understood. In this study, we examine how Internet attachment is related to anxiety and depression and assess the mediating effect of cyber victimization on these associations. Participants included 1,151 middle school students (51.4 percent males) aged 10 to 16 (M = 12.7, SD = 0.93). Structural equation models show that greater Internet attachment was associated with more cyber victimization and greater symptoms of anxiety and depression. Cyber victimization mediated the associations between Internet attachment and anxiety and between Internet attachment and depression. Implications for online awareness efforts are discussed.

    This article describes the development of the Lions-Quest Skills for Adolescence program. The primary purpose of this program is to respond to the needs of young people by helping them become more self aware, more skilled, more able to make positive and healthy choices, and better able to make informed, aware, and considered decisions about their own behavior. Skills for Adolescence is one school/community/parent-based curricular program that attempts to address health, life skills, and prevention issues in ways that have clearly struck a common chord in numerous countries. The program's emphasis on effective communication, on self-efficacy and social skills, and on strengthening the family appear to have a strong appear in many different contexts and cultures. Careful attention to local needs during adaptation while employing collaborative strategies is an essential ingredient to crossing cultural and national boundaries.

    Full Text Available The purpose of the study was to investigate the influence of human papillomavirus (HPV vaccination on adolescent girls' knowledge of HPV and HPV vaccine, perception of sexual risk and intentions for sexual debut. This cross-sectional comparative study was conducted in Ibanda and Mbarara districts. Data was collected using a standardized self-administered questionnaire and analyzed using the Statistical Package for the Social Sciences computer software. Univariate, bivariate, and logistic regression analyses were conducted with significance level set at p < .05. Results showed that HPV vaccination was associated with being knowledgeable (Crude OR: 5.26, CI: 2.32-11.93; p = 0.000. Vaccination against HPV did not predict perception of sexual risk. Knowledge was low (only 87/385 or 22.6% of vaccinated girls were knowledgeable, but predicted perception of a high sexual risk (Adjusted OR: 3.12, CI: 1.37-3.63; p = 0.008. HPV vaccination, knowledge and perceived sexual risk did not predict sexual behaviour intentions. High parental communication was associated with adolescent attitudes that support postponement of sexual debut in both bivariate and multiple regression analyses. In conclusion, findings of this study suggest that HPV vaccination is not likely to encourage adolescent sexual activity. Influence of knowledge on sexual behaviour intentions was not definitively explained. Prospective cohort studies were proposed to address the emerging questions.

    The investigation of self-reflective processing during adolescence is relevant, as this period is characterized by deep reorganization of the self-concept. It may be the case that an atypical development of brain regions underlying self-reflective processing increases the risk for psychological disorders and impaired social functioning. In this study, we investigated the neural bases of self- and other-related processing in typically developing adolescents and youths with 22q11.2 deletion syndrome (22q11DS), a rare neurogenetic condition associated with difficulties in social interactions and increased risk for schizophrenia. The fMRI paradigm consisted in judging if a series of adjectives applied to the participant himself/herself (self), to his/her best friend or to a fictional character (Harry Potter). In control adolescents, we observed that self- and other-related processing elicited strong activation in cortical midline structures (CMS) when contrasted with a semantic baseline condition. 22q11DS exhibited hypoactivation in the CMS and the striatum during the processing of self-related information when compared to the control group. Finally, the hypoactivation in the anterior cingulate cortex was associated with the severity of prodromal positive symptoms of schizophrenia. The findings are discussed in a developmental framework and in light of their implication for the development of schizophrenia in this at-risk population.

    Introduction: Adolescent idiopathic scoliosis is the most common type of scoliosis. A Cobb angle of 50° will progress beyond the age of spinal maturity. Surgery over bracing is advised at a Cobb angle above or equal to 50°. The aim of surgery is to bring the Cobb angle down below 50° to prevent reprogression as well as improve the quality of life. The objective of the study is to analyze the efficacy and significance in lifestyle improvement of pedicle screw-only fixation system versus the more common hybrid instrumentation system used for the surgical treatment of adolescent idiopathic scoliosis. Materials and Methods: A prospective cohort study was conducted involving two groups of patients were included in the study. One group was operated with pedicle screw-only method while the other with hybrid instrumentation system. The pre- and post-operative Cobb's angles were taken across a follow-up of 4 years. An SRS-30 questionnaire was given in a yearly follow-up to assess the lifestyle improvement of the patient. Results: Pedicle screw-only method was significantly more effective in reducing Cobb's angle (P = 0.0487). It was showed less loss of correction (P = 0.009) pedicle screw-only surgery was also better at reducing thoracic curves (P = 0.001). There seemed a better recovery time with pedicle screw surgery (P = 0.003). Conclusion: Pedicle screws are more effective and durable than hybrid systems at when treating adolescent idiopathic scoliosis. PMID:27695235

    2014-10-01

    The International PV Quality Assurance Task Force is developing a rating system that provides comparative information about the relative durability of PV modules. Development of accelerated stress tests that can provide such comparative information is seen as a major step toward being able to predict PV module service life. This paper will provide details of the ongoing effort to determine the format of such an overall module rating system. The latest proposal is based on using three distinct climate zones as defined in IEC 60721-2-1 for two different mounting systems. Specific stresses beyond those used in the qualification tests are being developed for each of the selected climate zones.

    We investigated the relationship between three factors--internal/external locus of control, self-esteem, and parental verbal interaction--for at-risk Black male adolescents in the United States. Forty-two male students in Grades 6, 7, and 8 who had been identified by their teachers as being at risk completed the Locus of Control Scale for Children (Nowicki & Strickland, 1973), the Self-Esteem Inventory (Coopersmith, 1967), and the Verbal Interaction Questionnaire (Blake, 1991). A moderate positive relationship found between self-esteem and parental verbal interaction was consistent with a previous finding for White high school students. A moderate negative relationship found between locus of control and self-esteem differed from a previous finding of no significant relationship for Black elementary children. A weak, yet significant, negative relationship was found between locus of control and parental verbal interaction.

    Full Text Available Objective: To investigate the agreement between two international criteria for classification of children and adolescents nutritional status. Methods: The study included 778 girls and 863 boys aged from six to 13 years old. Body mass and height were measured and used to calculate the body mass index. Nutritional status was classified according to the cut-off points defined by the World Health Organization and the International Obesity Task Force. The agreement was evaluated using Kappa statistic and weighted Kappa. Results: In order to classify the nutritional status, the agreement between the criteria was higher for the boys (Kappa 0.77 compared to girls (Kappa 0.61. The weighted Kappa was also higher for boys (0.85 in comparison to girls (0.77. Kappa index varied according to age. When the nutritional status was classified in only two categories - appropriate (thinness + accentuated thinness + eutrophy and overweight (overweight + obesity + severe obesity -, the Kappa index presented higher values than those related to the classification in six categories. Conclusions : A substantial agreement was observed between the criteria, being higher in males and varying according to the age.

    This Nigerian Ministry of Health speech reiterates the importance of focusing on the problems of youth and adolescents which was 1st identified in 1989 at a World Health Assembly. Every stage of the life cycle is important because mental, physical, psychological, and social scars are carried into the future. It is important to make the transition to adulthood as smooth as possible. Of the 30% (1.5 billion) of the World's population that are adolescents 10-24 years old, 80% live in developing countries. 50% of the world population is 25 years. In the preparation for adulthood, age-old customs, culture, and tradition have ensured the stability and survival of societies, but great changes have taken place due to colonialism, modern education, urban migration, rapid travel an communication, tourism, and trade. There is weakening of traditional marriage. Foreign cultural influence has armed youths to challenge community cultural norms and parental authority to direct their development. There is social tension, disruption, an instability. Adults as role models have sometimes failed to represent integrity and honesty. There is a need for sensitive support and guidance from adults. Peer pressure operates for both good or ill. Some will react to this stress to conform in unhealthy ways. The health care system may not fill adolescent needs because they are too old for the pediatrician and too young for the physician. Girls are particularly vulnerable to the problems of premarital pregnancy, induced abortion, out-of-wedlock births, and sexually transmitted diseases. The pressure is to grow up fast, particularly in polygamous societies where the woman has security only in her children. Opportunities for dialogue degenerate into sessions of being "talked at" and forced compliance. Unemployment is very high which can lead to loss of self-esteem, psychological stress, and hopelessness and sometimes street fighting, thuggery, drug pushing, and armed robbery.

    The study was aimed to verify, from a longitudinal perspective, whether perceived peer support would mediate the relationship between attachment and internalizing problems. Longitudinal participants included 482 adolescents (245 boys) aged 14-15 years in Wave 1 and 17-18 years in Wave 2. Participants in Wave 1 completed the Relationship Questionnaire, and those in Wave 2 completed the Social Support Questionnaire and the Youth Self-Report. Results showed that secure attachment positively predicted high levels of perceived peer support and negatively predicted internalizing problems, whereas fearful and preoccupied attachment negatively predicted perceived peer support and positively predicted internalizing problems. The mediation models showed that perceived peer support partially mediated the relationship between secure attachment and internalizing problems as well as between preoccupied attachment and internalizing problems and between fearful attachment and internalizing problems. Our results confirm the role of subjective perception of peer support in contributing to the prediction of internalizing problems beyond attachment styles.

    Objectives: Performance indicators are a popular mechanism for measuring the quality of healthcare to facilitate both quality improvement and systems management. Few studies make comparative assessments of different countries’ performance indicator frameworks. This study identifies and compares frameworks and performance indicators used in selected Organisation for Economic Co-operation and Development health systems to measure and report on the performance of healthcare organisations and local health systems. Countries involved are Australia, Canada, Denmark, England, the Netherlands, New Zealand, Scotland and the United States. Methods: Identification of comparable international indicators and analyses of their characteristics and of their broader national frameworks and contexts were undertaken. Two dimensions of indicators – that they are nationally consistent (used across the country rather than just regionally) and locally relevant (measured and reported publicly at a local level, for example, a health service) – were deemed important. Results: The most commonly used domains in performance frameworks were safety, effectiveness and access. The search found 401 indicators that fulfilled the ‘nationally consistent and locally relevant’ criteria. Of these, 45 indicators are reported in more than one country. Cardiovascular, surgery and mental health were the most frequently reported disease groups. Conclusion: These comparative data inform researchers and policymakers internationally when designing health performance frameworks and indicator sets. PMID:28228948

    This meta-analysis aimed at determining the efficacy of psychological and psychopharmacological interventions for children and adolescents suffering from symptoms of posttraumatic stress disorder (PTSD). A search using the Medline, PsycINFO, and PILOTS databases was conducted to identify randomized controlled trials (RCTs) for pediatric PTSD. The search resulted in 41 RCTs, of which 39 were psychological interventions and two psychopharmacological interventions. Results showed that psychological interventions are effective in treating PTSD, with aggregated effect sizes of Hedge's g=0.83 when compared to waitlist and g=0.41 when compared to active control conditions at posttreatment. Trauma-focused cognitive behavior therapy was the most researched form of intervention and resulted in medium to large effect sizes when compared to waitlist (g=1.44) and active control conditions (g=0.66). Experimental conditions were also more effective than control conditions at follow-up. Interventions were further effective in reducing comorbid depression symptoms, yet the obtained effect sizes were small to medium only. The findings indicate that psychological interventions can effectively reduce PTSD symptoms in children and adolescents. There is very little evidence to support use of psychopharmacological interventions for pediatric PTSD.

    While the problem of climate change is being perceived as increasingly urgent, decision-makers struggle to agree on the distribution of responsibility across countries. In particular, representatives from countries hosting emissions-intensive exporting industries have argued that the importers of emissions-intensive goods should bear the responsibility, and ensuing penalties. Indeed, international trade and carbon leakage appear to play an increasingly important role in the carbon emissions debate. However, definitions of quantities describing the embodiment of carbon emissions in internationally traded products, and their measurement, have to be sufficiently robust before being able to underpin global policy. In this paper we critically examine a number of emissions accounting concepts, examine whether the ensuing carbon balances are compatible with monetary trade balances, discuss their different interpretations, and highlight implications for policy. In particular, we compare the emissions embodied in bilateral trade (EEBT) method which considers total trade flows with domestic emission intensities, with the multi-regional input-output (MRIO) method which considers trade only into final consumption with global emission intensities. If consumption-based emissions of different countries were to be compared, we would suggest an MRIO approach because of the global emissions coverage inherent in this method. If trade-adjusted emission inventories were to be compared, we would suggest an EEBT approach due to the consistency with a monetary trade balance.

  17. Comparative internal anatomy of Staurozoa (Cnidaria), with functional and evolutionary inferences

    Comparative efforts to understand the body plan evolution of stalked jellyfishes are scarce. Most characters, and particularly internal anatomy, have neither been explored for the class Staurozoa, nor broadly applied in its taxonomy and classification. Recently, a molecular phylogenetic hypothesis was derived for Staurozoa, allowing for the first broad histological comparative study of staurozoan taxa. This study uses comparative histology to describe the body plans of nine staurozoan species, inferring functional and evolutionary aspects of internal morphology based on the current phylogeny of Staurozoa. We document rarely-studied structures, such as ostia between radial pockets, intertentacular lobules, gametoducts, pad-like adhesive structures, and white spots of nematocysts (the last four newly proposed putative synapomorphies for Staurozoa). Two different regions of nematogenesis are documented. This work falsifies the view that the peduncle region of stauromedusae only retains polypoid characters; metamorphosis from stauropolyp to stauromedusa occurs both at the apical region (calyx) and basal region (peduncle). Intertentacular lobules, observed previously in only a small number of species, are shown to be widespread. Similarly, gametoducts were documented in all analyzed genera, both in males and females, thereby elucidating gamete release. Finally, ostia connecting adjacent gastric radial pockets appear to be universal for Staurozoa. Detailed histological studies of medusozoan polyps and medusae are necessary to further understand the relationships between staurozoan features and those of other medusozoan cnidarians.

    Full Text Available This paper attempts to contribute to ways by which confluence, referring to a meeting point for the different agents to cooperate and communicate on education policy processes, can be understood. Pertinent national education policies in countries receiving aid, in particular, are formed and implemented in a complex nexus. Cultural and context sensitivity can be stimulated through a thorough understanding of this confluence, which subsequently can enable the different policy agents, which function at this meeting point, collaborate to alleviate some of the educational challenges. Comparative and international education, in this respect, has a significant role to play.

    The current study filled significant gaps in our knowledge of developmental psychopathology by examining the influence of multilevel risk factors and developmental assets on longitudinal trajectories of internalizing symptoms and self-esteem in an exceptionally culturally diverse sample of rural adolescents. Integrating ecological and social capital theories, we explored if positive microsystem transactions are associated with self-esteem while negative microsystem transactions increase the chances of internalizing problems. Data came from the Rural Adaptation Project, a 5-year longitudinal panel study of more than 4,000 middle school students from 28 public schools in two rural, disadvantaged counties in North Carolina. Three-level hierarchical linear modeling models were estimated to predict internalizing symptoms (e.g., depression, anxiety) and self-esteem. Relative to other students, risk for internalizing problems and low self-esteem was elevated for aggressive adolescents, students who were hassled or bullied at school, and those who were rejected by peers or in conflict with their parents. Internalizing problems were also more common among adolescents from socioeconomically disadvantaged families and neighborhoods, among those in schools with more suspensions, in students who reported being pressured by peers, and in youth who required more teacher support. It is likely that these experiences left adolescents disengaged from developing social capital from ecological microsystems (e.g., family, school, peers). On the positive side, support from parents and friends and optimism about the future were key assets associated with lower internalizing symptoms and higher self-esteem. Self-esteem was also positively related to religious orientation, school satisfaction, and future optimism. These variables show active engagement with ecological microsystems. The implications and limitations were discussed.

The risk of suffering from MS is 2.5–3.5 times greater in females than in males. While there is extant research on fatigue, depression, and cognitive impairment in patients with MS during its clinical course, there is a lack of research focusing on sleep, psychological functioning, and physical activity (PA at the point of disease onset. The aims of the present study were therefore, to assess the markers of mental toughness (MT as a dimension of psychological functioning, sleep disturbances (SD, and PA among patients at the moment of disease onset and to compare these with the corresponding values for healthy adolescents and young adults. Methods: A total of 23 patients with MS at disease onset (mean age =32.31 years; 91% females, 23 healthy adolescents (mean age =17.43 years; 82% females, and 25 healthy young adults (mean age =20.72 years; 80% females took part in the study. They completed questionnaires covering sociodemographic data, MT, SD, and PA. Results: Patients with MS had similar scores for MT traits as those in healthy

    Full Text Available Introduction: Adolescents and young adults with congenital heart disease [CHD] show a range of memory deficits, which can dramatically impact their clinical outcomes and quality of life. However, few studies have identified predictors of these memory changes. The purpose of this investigation was to identify predictors of memory deficits in adolescents and young adults with CHD after surgical palliation compared to healthy controls. Method: 156 adolescents and young adults [80 CHD and 76 controls; age 14-21 years] were recruited and administered an instrument to assess memory [Wide Range Assessment of Memory and Learning 2nd Edition – general memory index (GMI score] and completed questionnaires that measure anxiety, depression, sleepiness, health status, and self-efficacy. Descriptive and non-parametric statistics were used to assess group differences, and logistic regression to identify predictors of memory deficits. Results: CHD subjects consisted of 58% males, median age 17 years, 41% Hispanic, and medians of 2 previous heart surgeries and 14 years since last surgery. Memory deficits [GMI < 85] were identified in 50% CHD compared to 4% healthy controls [median GMI 85 vs. 108, p <0.001]. Of GMI subscale medians, CHD subjects had significantly worse memory performance vs. healthy controls [verbal 88 vs. 105, p <0.001; attention 88 vs. 109, p<0.001; working memory 86 vs. 108, p <0.001]. No significant differences appeared between groups for visual memory. Multiple clinical and psychosocial factors were identified which were statistically different on bivariate analyses between the subjects with and without memory deficits. By multivariate analysis, male gender, number of surgeries, anxiety, and self-efficacy emerged as independent predictors of memory deficits. Conclusion: Adolescents and young adults with CHD, more than a decade since their last surgery, show significant verbal, attention and working memory deficits over controls. To enhance

    At least two leading developmental models of borderline personality disorder (BPD) emphasize the role of accurate reflection and understanding of internal states as significant to the development of BPD features (Fonagy, Int J Psycho-Anal 72:639-656, 1991; Linehan, Cognitive-behavioral treatment of borderline personality disorder, 1993). The current study used the construct of experiential avoidance (EA) to operationalize avoidance of internal states and sought to examine (1) the concurrent relations between EA and borderline features in a large and diverse community sample; and (2) the prospective relation between EA and borderline features over a 1-year follow-up, controlling for baseline levels of borderline features. N = 881 adolescents recruited from public schools in a large metropolitan area participated in baseline assessments and N = 730 completed follow-up assessments. Two main findings were reported. First, EA was associated with borderline features, depressive, and anxiety symptoms at the bivariate level, but when all variables were considered together, depression and anxiety no longer remained significantly associated with borderline features, suggesting that the relations among these symptom clusters may be accounted for by EA as a cross-cutting underlying psychological process. Second, EA predicted levels of borderline symptoms at 1-year follow-up, controlling for baseline levels of borderline symptoms, and symptoms of anxiety and depression. Results are interpreted against the background of developmental theories of borderline personality disorder.

    Introduction Attention-deficit/hyperactivity disorder (ADHD) is a major public health issue. Pharmacological treatments play an important role in the multimodal treatment of ADHD. Currently, there is a lack of up-to-date and comprehensive evidence on how available ADHD drugs compare and rank in terms of efficacy and tolerability, in children or adolescents as well as in adults. We will conduct a network meta-analysis (NMA), integrating direct and indirect comparisons from randomised controlled trials (RCTs), to rank pharmacological treatments for ADHD according to their efficacy and tolerability profiles. Methods and analysis We will search a broad range of electronic databases, including PubMed, MEDLINE, EMBASE, PsycINFO, ERIC and Web of Science, with no date or language restrictions. We will also search for unpublished studies using international clinical trial registries and contacting relevant drug companies. We will identify and include available parallel-group, cross-over and cluster randomised trials that compare methylphenidate, dexmethylphenidate, amphetamine derivatives (including lisdexamfetamine), atomoxetine, clonidine, guanfacine, bupropion or modafinil (as oral therapy) either with each other or to placebo, in children, adolescents or adults with ADHD. Primary outcomes will be efficacy (indicated by reduction in severity of ADHD core symptoms measured on a standardised scale) and tolerability (the proportion of patients who left a study early due to side effects). Secondary outcomes will be global functioning, acceptability (proportion of patients who left the study early by any cause) and changes in blood pressure and body weight. NMA will be conducted in STATA within a frequentist framework. The quality of RCTs will be evaluated using the Cochrane risk of bias tool, and the quality of the evidence will be assessed using the GRADE approach. Subgroup and sensitivity analyses will be conducted to assess the robustness of the findings. Ethics and

    Childhood obesity is associated with biologic and behavioral characteristics that may impact bone mineral density (BMD) and structure. The objective was to determine the association between obesity and bone outcomes, independent of sexual and skeletal maturity, muscle area and strength, physical activity, calcium intake, biomarkers of inflammation, and vitamin D status. Tibia and radius peripheral quantitative CT scans were obtained in 91 obese (BMI>97th percentile) and 51 non-obese adolescents (BMI>5th and Tibia cortical section modulus and calf muscle area Z-scores were greater in obese participants (1.07 and 1.63, respectively, both pTibia and radius trabecular and cortical volumetric BMD did not differ significantly between groups. Calf muscle area and strength Z-scores, advanced skeletal maturity, and physical activity (by accelerometry) were positively associated with tibia cortical section modulus Z-scores (all ptibia section modulus Z-scores between obese and non-obese participants from 1.07 to 0.28. After multivariate adjustment for greater calf muscle area and strength Z-scores, advanced maturity, and less moderate to vigorous physical activity, tibia section modulus Z-scores were 0.32 (95% CI -0.18, 0.43, p=0.06) greater in obese, vs. non-obese participants. Radius cortical section modulus Z-scores were 0.45 greater (p=0.08) in obese vs. non-obese participants; this difference was attenuated to 0.14 with adjustment for advanced maturity. These findings suggest that greater tibia cortical section modulus in obese adolescents is attributable to advanced skeletal maturation and greater muscle area and strength, while less moderate to vigorous physical activities offset the positive effects of these covariates. The impact of obesity on cortical structure was greater at weight bearing sites.

    Internalizing symptoms during adolescence and beyond is a major public health concern, particularly because severe symptoms can lead to the diagnosis of a number of serious psychiatric conditions. This study utilizes a unique sample with a complex statistical method in order to explore Gene × Environment interactions found in internalizing symptoms during adolescence. Data for this study were drawn from a longitudinal prevention intervention study (n = 798) of Baltimore city school children. Internalizing symptom data were collected using self-report and blood or saliva samples genotyped using Affymetrix 6.0 microarrays. A major depression polygenic score was created for each individual using information from the major depressive disorder Psychiatric Genetics Consortium and used as a predictor in a latent trait-state-occasion model. The major depressive disorder polygenic score was a significant predictor of the stable latent trait variable, which captures time-independent phenotypic variability. In addition, an early childhood stressor of death or divorce was a significant predictor of occasion-specific variables. A Gene × Environment interaction was not a significant predictor of the latent trait or occasion variables. These findings support the importance of genetics on the stable latent trait portion of internalizing symptoms across adolescence.

    This paper, summarizing the March 2012 presentation at the second international workshop of the Canadian Task Force on Adolescents and Young Adults with Cancer, describes the situation in Italy concerning the inadequate access to optimal cancer services for adolescents, and the need to improve the quality of care for these patients while investing in more research on the diseases that afflict them. National actions to bridge the gap in care and implement specific programs tailored to these patients arose from the pediatric oncology community. These actions include creation of the national Committee on Adolescents of the Associazione Italiana Ematologia Oncologia Pediatrica (AIEOP), founded with the mission of ensuring that Italian adolescents with cancer have prompt, adequate, and equitable access to the best care to optimize their treatment outcome and quality of life. Also developed was the Youth Project of the pediatric oncology unit at the Istituto Nazionale Tumori in Milan, which is currently dedicated to adolescents aged 15-19 years old and may eventually serve young adults up to the age of 25 that are affected by pediatric-type tumors.

    Anxiety and mood disorders are among the most prevalent mental health problems affecting our youth. We propose that assessment and treatment efforts in this area can benefit from a focus on developmentally sensitive neurobehavioral trait constructs, that is, individual difference constructs with direct referents in both neurobiology and behavior across the lifespan. This approach dovetails with the National Institute of Mental Health's Research Domain Criteria initiative, which aims to improve classification and treatment of psychopathology by delineating dimensions of functioning that transcend measurement domains and traditional diagnostic categories. We highlight two neurobehavioral dimensions with clear relevance for understanding internalizing problems at differing ages: (a) defensive reactivity and (b) cognitive control. Individual differences in defensive reactivity are posited to reflect variations in sensitivity of the brain's negative valence systems, whereas differences in cognitive control are theorized to reflect variations in neural systems dedicated to regulating behavior and affect. Focusing on these target constructs, we illustrate a psychoneurometric approach to assessment of internalizing psychopathology entailing use of neural, self-report, and behavioral indicators. We address the feasibility of the psychoneurometric approach for clinical application and present results from a pilot study demonstrating expected associations for neural, parent-report, and behavioral measures of defensive reactivity and cognitive control with internalizing symptoms in preschoolers. Together, our conceptual and empirical analyses highlight the promise of multimethod, dimensional assessment of internalizing psychopathology in the lab and in the clinic.

    This study compares the performance of a field bioretention cell with and without an internal water storage (IWS) layer for treating highway runoff. Both synthetic and natural runoff tests were conducted. Hydraulic performances on peak discharge reduction and detention time extension were measured. Pollutant removal efficiencies were evaluated for total suspended solids (TSS), copper (Cu), lead (Pb), zinc (Zn), total nitrogen, nitrate, ammonia, total phosphorus, and orthophosphate phosphorus. Pollutants in soil media were measured. Results reveal that both IWS and non-IWS designs reduced peak discharge and extended detention time, while the IWS design performed better. For water quality performance, the non-IWS design removed TSS, Cu, Pb, Zn, and total phosphorus to varying degrees of efficiency, but total nitrogen removal was minimal. The IWS layer significantly improved removal efficiencies for TSS, Cu, Zn, nitrogen, and phosphorus. Soil media accumulated some metals over time.

    This study focuses on the comparison of the Uniform Building Code (UBC) 1997 and International Building Code (IBC) 2003 in relation to the seismic design and analysis of special steel moment resisting frame buildings (SMRF).This paper formulates a numerical study of a steel SMRF building, studied in four different situations, namely: as an office building in San Francisco; as an office building in Sacramento; as an essential facility in San Francisco, and as an essential facility in Sacramento. The analytical results of the model buildings are then compared and analyzed taking note of any significant differences. This case study explores variations in the results obtained using the two codes, particularly the design base shear and drift ratios as they relate to different locations and occupancy use. This study also proves that IBC 2003is more stringent for the redundancy factor under design category E for the SMRF building, and drift limits for essential facilities.

    Full Text Available Abstract Background There is a lack of population-based long-term longitudinal research on mental health status and functional physical/somatic symptoms. Little is known about the long-term mental health outcomes associated with somatic symptoms or the temporal relationship between depression and such symptoms. This 15-year study followed up adolescents with depression and matched controls, screened from a population-based sample, who reported different numbers of somatic symptoms. Methods The total population of 16–17-year-olds in Uppsala, Sweden, was screened for depression in 1991–1993. Adolescents who screened positive and an equal number of healthy controls took part in a semi-structured diagnostic interview. In addition, 21 different self-rated somatic symptoms were assessed. Sixty-four percent of those adolescents participated in a follow-up structured interview 15 years later. Results Somatic symptoms in adolescence predicted depression and other adult mental disorders regardless of the presence of adolescent depression. In adolescents with depression, the number of functional somatic symptoms predicted, in a dose response relationship, suicidal behavior, bipolar episodes, and psychotic episodes as well as chronic and recurrent depression. Contrary to expectations, the somatic symptoms of abdominal pain and perspiration without exertion better predicted depression than all DSM-IV depressive symptoms. Abdominal pain persisted as an independent strong predictor of depression and anxiety, even after controlling for other important confounders. Conclusions Somatic symptoms in adolescence can predict severe adult mental health disorders. The number of somatic symptoms concurrent with adolescent depression is, in a stepwise manner, linked to suicidal attempts, bipolar disorders, psychotic disorders, and recurrent and chronic depression. These findings can be useful in developing treatment guidelines for patients with somatic symptoms.

    Tumoural portal vein thrombosis (PVT) is a major prognostic factor in hepatocellular carcinoma (HCC). The efficacy of sorafenib, the only treatment approved at an advanced stage, is limited. Based on previous data, selective internal radiation therapy (SIRT), or {sup 90}Y radioembolization, seems an interesting option. We aimed to compare both treatments in this population. We retrospectively compared patients treated in two centres for HCC with tumoural PVT. We compared overall survival (OS) between patients treated with SIRT and patients treated with sorafenib. Analyses were performed before and after 1:1 matching with a propensity score for controlling indication bias, using a Cox proportional hazards model. A total of 151 patients were analysed, 34 patients treated with SIRT and 117 patients treated with sorafenib only. In the whole population, SIRT was associated with a higher median OS as compared with sorafenib: 18.8 vs 6.5 months (log-rank p < 0.001). There was an imbalance of baseline characteristics between patients treated by SIRT and sorafenib, which justified patient matching with use of a propensity score: 24 patients treated with SIRT could be matched with 24 patients treated with sorafenib. OS was estimated with a median of 26.2 vs 8.7 months in patients treated with SIRT vs sorafenib, respectively (log-rank p = 0.054). Before and after patient matching, the adjusted hazard ratio related to treatment by SIRT was estimated at 0.62 [95 % confidence interval (CI) 0.39-0.97] (p = 0.037) and 0.40 (95 % CI 0.19-0.82) (p = 0.013), respectively. SIRT seems more effective than sorafenib in patients presenting with HCC and tumoural PVT. This hypothesis is being tested in prospective randomized trials. (orig.)

    2016-04-01

    Smoking and drinking constitute two risk factors contributing to the rising burden of non-communicable diseases in low- and middle-income countries. Both issues have gained increased international attention, but tobacco control has made more sustained progress in terms of international and domestic policy commitments, resources dedicated to reducing harm, and reduction of tobacco use in many high-income countries. The research presented here offers insights into why risk factors with comparable levels of harm experience different trajectories of global attention. The analysis focuses particular attention on the role of dedicated global health networks composed of individuals and organizations producing research and engaging in advocacy on a given health problem. Variation in issue characteristics and the policy environment shape the opportunities and challenges of global health networks focused on reducing the burden of disease. What sets the tobacco case apart was the ability of tobacco control advocates to create and maintain a consensus on policy solutions, expand their reach in low- and middle-income countries and combine evidence-based research with advocacy reaching beyond the public health-centered focus of the core network. In contrast, a similar network in the alcohol case struggled with expanding its reach and has yet to overcome divisions based on competing problem definitions and solutions to alcohol harm. The tobacco control network evolved from a group of dedicated individuals to a global coalition of membership-based organizations, whereas the alcohol control network remains at the stage of a collection of dedicated and like-minded individuals.

    Full Text Available This paper compares the development of alcohol and cannabis use in two English and German adolescent cohorts, using longitudinal data from ongoing studies located in Peterborough and Duisburg respectively. We set out the two studies and detail the steps taken to make the comparisons presented. Unusually, this paper assesses this development simultaneously in both cohorts, using an under-utilized variation of a well-known technique (multiple-group multiple-cohort latent growth curve modelling. In keeping with expectations from other research, there are large differences in the proportions of young people in the two countries using cannabis and alcohol. The Peterborough cohort embarked on earlier initiation of both alcohol and cannabis use, and increase their frequency of use very quickly. Despite a one year chronological gap between the two study cohorts, the 13 year old Peterborough group drink (until drunk and smoke cannabis at the same level as the 15 year old versions of their German counterparts. Although there are some methodological differences between the two projects, the results appear to be valid.In questo articolo viene svolta una comparazione sullo sviluppo, nel corso dell’adolescenza, del consumo di droghe leggere e alcol tra un campione di giovani tedeschi e inglesi, utilizzando i dati di due studi longitudinali panel condotti rispettivamente in Germania e in Inghilterra.

Alguns resultados da pesquisa "Responsabilidade e garantias ao adolescente autor de ato infracional: uma proposta de revisão do ECA em seus 18 anos de vigência" apoiada pela Secretaria de Assuntos Legislativos do Ministério da Justiça, ilustram as dificuldades de mplementação dos preceitos legais, possibilitando refletir se é a textura aberta da lei o que vem favorecendo a persistência de argumentos extrajurídicos e ideológicos em sua interpretação.Since its approval, The Child and Adolescent Act has been attacked for several critics in the public debate. However neither the specialized dogmatic nor jurisprudence have presented effective efforts to the comprehension of the law or its principles, especially related to internment measures applied to young offenders. the text shows the homogeneous appearance of the brazilian jurisprudence into the State Courts, according to the most used arguments by the decisions. some results from the "Responsibility and Guarantees to young offender: a revision proposal for the child and adolescent act in 18 years of existence" research illustrate these difficulties to implement the legislation, avoiding the consideration regarding the open texture of the law as a possible cause for the persistence of extralegal and ideological arguments on its interpretation.

    Full Text Available Background: The effect of correcting static vision on sports vision is still not clear. Aim: To examine whether sports vision (depth perception [DP], dynamic visual acuity [DVA], eye movement [EM], peripheral vision [PV], and momentary vision [MV], were different among soft tennis adolescent athletes with normal vision (Group A, with refractive error and corrected with (Group B and without eyeglasses (Group C. Setting and Design: A cross-section study was conducted. Soft tennis athletes aged 10–13 who played softball tennis for 2–5 years, and who were without any ocular diseases and without visual training for the past 3 months were recruited. Materials and Methods: DPs were measured in an absolute deviation (mm between a moving rod and fixing rod (approaching at 25 mm/s, receding at 25 mm/s, approaching at 50 mm/s, receding at 50 mm/s using electric DP tester. A smaller deviation represented better DP. DVA, EM, PV, and MV were measured on a scale from 1 (worse to 10 (best using ATHLEVISION software. Statistical Analysis: Chi-square test and Kruskal–Wallis test was used to compare the data among the three study groups. Results: A total of 73 athletes (37 in Group A, 8 in Group B, 28 in Group C were enrolled in this study. All four items of DP showed significant difference among the three study groups (P = 0.0051, 0.0004, 0.0095, 0.0021. PV displayed significant difference among the three study groups (P = 0.0044. There was no significant difference in DVA, EM, and MV among the three study groups. Conclusions: Significant better DP and PV were seen among soft tennis adolescent athletes with normal vision than those with refractive error regardless whether they had eyeglasses corrected. On the other hand, DVA, EM, and MV were similar among the three study groups.

    2016-05-01

    The International Sunspot Numbers (ISN; Version 2) have been recently (2015) revised at the Sunspot Index and Long Term Solar Observations maintained at Royal Observatory of Belgium (http://www.sidc.be/silso/datafiles). ISN is a reconciled aggregate over several ground-based observatories, mostly using hand-drawn sunspot recordings. We make a detailed 10-year comparisons between the Improved Solar Observing Optical Network’s prototype digital data (2002-2011) and the ISN V1 (Version 1; pre-2015), and ISN V2. Over the ~ 10-year period, ISN V1 underestimates the sunspot number counts by up to 40% while the ISN V2 overestimates by a similar amount. We also compare the hand-drawn data from a single telescope at the National Solar Observatory with the digital data and ISN numbers. These comparisons reveal caveats that need to be taken into account, as sunspot numbers are used to forecast both the solar cycle and the near term climatology of solar cycle impacts on the space environment.

    2011-05-01

    This investigation examined the relation between developmental trajectories jointly estimated for social and physical aggression and adjustment problems at age 14. Teachers provided ratings of children's social and physical aggression in Grades 3, 4, 5, 6, and 7 for a sample of 255 children (131 girls, 21% African American, 52% European American, 21% Mexican American). Participants, parents, and teachers completed measures of the adolescent's adjustment to assess internalizing symptoms, rule-breaking behaviors, and borderline and narcissistic personality features. Results showed that membership in a high and rising trajectory group predicted rule-breaking behaviors and borderline personality features. Membership in a high desister group predicted internalizing symptoms, rule-breaking behaviors, and borderline and narcissistic personality features. The findings suggest that although low levels of social and physical aggression may not bode poorly for adjustment, individuals engaging in high levels of social and physical aggression in middle childhood may be at greatest risk for adolescent psychopathology, whether they increase or desist in their aggression through early adolescence.

    Full Text Available Background: Obesity is a major risk factor for chronic diseases and has a role on high blood pressure, diabetes type II, etc., This review assesses the prevalence of Iranian children obesity and overweight for different age categories and compares the three standard definitions of obesity. Materials and Methods: To retrieve desirable studies concerning childhood anthropometric data from different area of Iran, the MEDLINE, Scopus, and different local databases such as Scientific Information database were used. The studies reported the prevalence of obesity or overweight of children < 6, 6–12, and 12–20 years old, despite differences between definitions of childhood obesity, were included in the study. We combined the reported prevalence of the overweight and obesity with regard to age and gender, and also by the different standard references which are the Centers for Disease Control and Prevention (CDC, the World Health Organization (WHO definition, and the International Obesity Task Force (IOTF references. The analysis was carried out using STATA software. Results: Our review covered 75 articles reported the prevalence of overweight or obesity among children and adolescents for different age groups in Iran. Our meta-regression analysis showed that the prevalence of obesity and overweight did not vary significantly in gender and age categories, but different definitions provide different prevalence of overweight and obesity. Conclusion: The effective factors on obesity and overweight included administration policy and organizational, interpersonal, intrapersonal, and social factors. CDC and WHO references intended in monitoring children's growth and the IOTF cutoffs would rather provide a common set of definitions that researchers and policymakers could use for descriptive and comparative purposes.

    Disruptive Behavior Disorders (DBDs) are among the most common reasons for youth referrals to mental health clinics. Aim of this study is to compare short and medium term efficacy of a multimodal treatment program (MTP), compared to community care (treatment-as-usual, TAU). The sample included 135 youths with DBDs (113 males, age range 9-15 years, mean age 12±2.5 years) were assigned either to a MTP (n=64), or addressed to community care for a TAU (n=71). Outcome measures were the Child Behaviour Checklist (CBCL) and the Children's Global Assessment Scale (C-GAS). All subjects were assessed at the baseline (T0), after 1-year treatment (T1) and after a 2-year follow-up (T2). Compared with patients receiving TAU, youths in the MTP showed, both at T1 and T2, significantly lower scores on CBCL Externalizing Scale, Internalizing Scale, Anxious/Depressed, Social Problems, and Aggressive Behavior, and higher scores at the C-GAS. Improvement in Internalizing Scales was particularly evident, with a shift from the clinical to the non-clinical range. Rate of use of mental health services and scholastic failure were reduced in the MTP. It is suggested that the improvement of the Internalizing symptoms is a crucial component of the therapeutic process in this MTP.

    2016-01-01

    As society continues to advocate an unrealistically thin body shape, awareness and internalization of appearance and its consequent impact upon self-esteem has become increasingly of concern, particularly in adolescent girls. School gender environment may influence these factors, but remains largely unexplored. This study aimed to assess differences between two different school environments in appearance attitudes, social influences and associations with self-esteem. Two hundred and twelve girls (M = 13.8 years) attending either a single-sex or co-educational school completed measures on socio-cultural attitudes towards appearance, social support and self-esteem. Though marginal differences between school environments were found, significantly higher internalization was reported among girls at the co-educational school. School environment moderated relations between internalization and self-esteem such that girls in co-educational environments had poorer self-esteem stemming from greater internalization. Thus, in a single-sex school environment, protective factors may attenuate negative associations between socio-cultural attitudes towards appearance and self-esteem in adolescent girls.

    Pizza is a popular food that can contribute to high intakes of saturated fat and sodium among children and adolescents. The objective of this study was to compare daily nutrient intakes when a pizza product meeting the US Department of Agriculture's criteria for competitive food entrées under the HealthierUS School Challenge (HUSSC) was substituted for usual pizza products consumed during foodservice-prepared school lunch. The study used National Health and Nutrition Examination Survey (2005-2008) dietary recall data from a cross-sectional sample of US children and adolescents (age 5 to 18 years, n=337) who ate pizza during school lunch on 1 day of dietary recall. Daily nutrient intakes based on the consumption of usual pizza products for school lunch (pre-modeled) were compared with intakes modeled by substituting nutrient values from an HUSSC whole-grain pizza product (post-modeled). Paired t tests were used to make the comparison. Post-modeled intakes were lower in daily energy, carbohydrate, total fat, saturated fat, cholesterol, and sodium compared with pre-modeled intakes among children and adolescents (Ppizza product for usual pizza products may significantly improve dietary quality of children and adolescents eating pizza for school lunch, indicating that it could be an effective approach to improve the nutritional quality of school lunch programs.

    2015-07-01

    Purpose: The midventilation (midV) approach can be used to take respiratory-induced pancreatic tumor motion into account during radiation therapy. In this study, the dosimetric consequences for organs at risk and tumor coverage of using a midV approach compared with using an internal target volume (ITV) were investigated. Methods and Materials: For each of the 18 patients, 2 treatment plans (25 × 2.0 Gy) were created, 1 using an ITV and 1 using a midV approach. The midV dose distribution was blurred using the respiratory-induced motion from 4-dimensional computed tomography. The resulting planning target volume (PTV) coverage for this blurred dose distribution was analyzed; PTV coverage was required to be at least V{sub 95%} >98%. In addition, the change in PTV size and the changes in V{sub 10Gy}, V{sub 20Gy}, V{sub 30Gy}, V{sub 40Gy}, D{sub mean} and D{sub 2cc} for the stomach and for the duodenum were analyzed; differences were tested for significance using the Wilcoxon signed-rank test. Results: Using a midV approach resulted in sufficient target coverage. A highly significant PTV size reduction of 13.9% (P<.001) was observed. Also, all dose parameters for the stomach and duodenum, except the D{sub 2cc} of the duodenum, improved significantly (P≤.002). Conclusions: By using the midV approach to account for respiratory-induced tumor motion, a significant PTV reduction and significant dose reductions to the stomach and to the duodenum can be achieved when irradiating pancreatic tumors.

  19. Internal Consistency and Power When Comparing Total Scores from Two Groups.

    2016-01-01

    Researchers now know that when theoretical reliability increases, power can increase, decrease, or stay the same. However, no analytic research has examined the relationship of power to the most commonly used type of reliability-internal consistency-and the most commonly used measures of internal consistency, coefficient alpha and ICC(A,k). We examine the relationship between the power of independent samples t tests and internal consistency. We explicate the mathematical model upon which researchers usually calculate internal consistency, one in which total scores are calculated as the sum of observed scores on K measures. Using this model, we derive a new formula for effect size to show that power and internal consistency are influenced by many of the same parameters but not always in the same direction. Changing an experiment in one way (e.g., lengthening the measure) is likely to influence multiple parameters simultaneously; thus, there are no simple relationships between such changes and internal consistency or power. If researchers revise measures to increase internal consistency, this might not increase power. To increase power, researchers should increase sample size, select measures that assess areas where group differences are largest, and use more powerful statistical procedures (e.g., ANCOVA).

    Arctic peoples today find themselves on the front line of rapid environmental change brought about by globalizing forces, shifting climates, and destabilizing physical conditions. The weather is not the only thing undergoing rapid change here. Social climates are intrinsically connected to physical climates, and changes within each have profound effects on the daily life, health, and well-being of circumpolar indigenous peoples. This paper describes a collaborative effort between university researchers and community members from five indigenous communities in the circumpolar north aimed at comparing the experiences of indigenous Arctic youth in order to come up with a shared model of indigenous youth resilience. The discussion introduces a sliding scale model that emerged from the comparative data analysis. It illustrates how a "sliding scale" of resilience captures the inherent dynamism of youth strategies for "doing well" and what forces represent positive and negative influences that slide towards either personal and communal resilience or vulnerability. The model of the sliding scale is designed to reflect the contingency and interdependence of resilience and vulnerability and their fluctuations between lowest and highest points based on timing, local situation, larger context, and meaning.

    Full Text Available With the emergence of globalization, it has become increasingly important for all citizens to possess an international perspective. The trend of internationalizing educational systems has also emerged in various countries. Thus, to explore the degree to which students can possess international perspectives is an important topic worthy of studying. The purpose of this study was to develop a questionnaire to investigate the current status of the international perspectives of and the differences between sixth graders in Taipei and Shanghai. A total of 1,300 sixth -graders were randomly stratified from the two cities, with 1,111 valid questionnaires returned for further analysis. A significant difference was found in sixth graders’ international perspectives between the two cities. Differences of their demographic characteristics were also identified. More similarities than differences in their backgrounds and experiences were identified. Both similarities and differences were also found in their parents’ level of education and occupation.

    Previous studies on self-esteem development show substantial changes as well as interindividual differences in change from adolescence to young adulthood. However, the processes underlying these developmental trajectories are still not well understood. The aim of the present study was to shed light on the macro- and microprocesses of self-esteem development. We investigated a sample of 876 German high school students (M = 16.0 years at Time 1) participating in an international exchange year. Exchange students provided 3 waves of trait self-esteem data (shortly before they departed, immediately after return, and 1 year later), as well as 9 monthly state measures of self-esteem and social inclusion during their stay abroad. In addition, a control group of high school students who stayed in Germany (N = 714) provided 2 waves of trait self-esteem data. From a macroperspective, results showed an effect of student exchange on trait self-esteem development: Exchange students showed a steeper mean-level increase and a lower rank-order stability compared with control students. Zooming in on the microprocesses underlying these developmental patterns, we found trait changes in exchange students to be mediated by state changes in self-esteem during their exchange. These fluctuations in state self-esteem were found to be predicted by feelings of social inclusion in the host country, and vice versa, providing support for both sociometer and self-broadcasting perspectives on self-esteem dynamics. In sum, our findings emphasize the importance of incorporating a microanalytical approach when investigating self-esteem development by showing that the environment triggers changes in this relatively stable personality trait through changes in states.

    Full Text Available The question of what deters crime is of both theoretical and practical interest. The present paper focuses on what factors deter minor, non-violent crimes, i.e. dishonest actions that violate the law. Much research has been devoted to testing the effectiveness of legal sanctions on crime, while newer models also include social sanctions (judgment of friends or family and internal sanctions (feelings of guilt. Existing research suggests that both internal sanctions and, to a lesser extent, legal sanctions deter crime, but it is unclear whether this pattern is unique to Western countries or robust across cultures. We administered a survey study to participants in China, Colombia, Germany, Portugal, and USA, five countries from distinct cultural regions of the world. Participants were asked to report the likelihood of engaging in seven dishonest and illegal actions, and were asked to indicate the probability and severity of consequences for legal, friend, family, and internal sanctions. Results indicated that across countries, internal sanctions had the strongest deterrent effects on crime. The deterrent effects of legal sanctions were weaker and varied across countries. Furthermore, the deterrent effects of legal sanctions were strongest when internal sanctions were lax. Unexpectedly, social sanctions were positively related to likelihood of engaging in crime. Taken together, these results suggest that the relative strengths of legal and internal sanctions are robust across cultures and dishonest actions.

    Introduction: Age estimation is a preliminary step in the identification of an individual. It is a crucial and often most critical step for forensic experts. The assessment has been standardized utilizing common dental diagnostic x-rays, but most such age-estimating systems are European population-based and their applicability has not been determined in the context of the Indian population. Aims and Objectives: To assess the applicability and to compare the methods of dental age estimation by Demirjian's method and the same method as modified by Willems (i.e. the Willems method) in Indian children of the National Capital Region (NCR). Also, to find a correlation among skeletal maturity using the Cervical vertebrae maturation index (CVMI), dental maturity, and chronological age in the same population. Materials and Methods: This cross-sectional study was conducted using dental radiographs of 70 orthodontic patients (37 males, 33 females) in the age range 9-16 years selected by simple random sampling. pantomogram were used to estimate dental age by Demirjian's method and the Willems method using their scoring tables. Lateral cephalograms were used to estimate skeletal maturity using CVMI. The latter was compared with Demirjian's stage for mandibular left second molar. Results: Overestimation of age among males by 0.856 years and 0.496 years was found by Demirjian's and the Willems methods, respectively. Among females, both the methods underestimated the age by 0.31 years and 0.45 years, respectively. Demirjian's stage G corresponded to CVMI stage 3 in males and stage 2 in females. Conclusion: In our study, the Willems method has proved to be more accurate for age estimation among Indian males, and Demirjian's method for Indian females. A statistically significant association appeared between Demirjian's stages and CVMI among both males and females. Our study recommends the derivation of a regression formula by studying a larger section of the Indian population

    In responding to the UK government's market forces model, some National Health Service (NHS) managers have introduced private sector concepts such as 'customer care' and 'total quality management' (TQM). Private sector firms find that success of these techniques is dependent upon creating an internal marketing orientation across the entire organization. To determine how internal marketing is being applied, a comparative survey of UK service sector firms and NHS units was undertaken using a modified version of Parasuraman's SERVQUAL model. All respondents indicated existence of type 1, 2, 3 and 4 gaps in the internal customer management process within their organizations. Major influencers of service gaps include departments placing internal efficiency ahead of internal customers and insufficient understanding of internal customer requirements. The survey indicated that, in certain areas of managing service quality, the NHS is performing better than its private sector counterparts. Nevertheless, opportunity for enhancing service quality in the NHS is possible through improving the flow of information between departments, stronger orientation towards meeting customer needs, upgrading provision systems and changing intradepartmental culture. The constraint facing the NHS manager is the limited availability of resources. One solution is to allocate resources in relation to service priorities. A directional planning matrix is presented as a tool for developing an optimum internal customer management strategy within an NHS unit.

The purpose of this study was to compare the content of participation instruments using the ICF classification. Methods A systematic literature search was conducted to identify instruments that assess participation according to the ICF. Instruments were considered to assess participation and were included if the domains contain content from a minimum of three ICF chapters ranging from Chapter 3 Communication to Chapter 9 Community, social and civic life in the activities and participation component. The instrument content was examined by first identifying the meaningful concepts in each question and then linking these concepts to ICF categories. The content analysis included reporting the 1 ICF chapters (domains covered in the activities and participation component, 2 relevance of the meaningful concepts to the activities and participation component and 3 context in which the activities and participation component categories are evaluated. Results Eight instruments were included: Impact on Participation and Autonomy, Keele Assessment of Participation, Participation Survey/Mobility, Participation Measure-Post Acute Care, Participation Objective Participation Subjective, Participation Scale (P-Scale, Rating of Perceived Participation and World Health Organization Disability Assessment Schedule II (WHODAS II. 1351 meaningful concepts were identified in the eight instruments. There are differences among the instruments regarding how participation is operationalized. All the instruments cover six to eight of the nine chapters in the activities and participation component.

    Full Text Available Sovereign funds are an important actor occurring on international financial markets in the last decade, being, in fact, state controlled international investments. Generally, they are financed from foreign currency reserves of the emergent countries they are constituted in, being managed apart of the official reserves and used for external expansion; they are likely to be detrimental to certain strategic interests. As public financial vehicles, they own, endorse or manage public funds of some emergent countries, freely invested by them in a great number of assets, being seen as a foreign policy element.

    The health effects of eating disorders (EDs) in adolescence have been widely studied, but their impact on present adolescent psychosocial adjustment and development have been overseen. This study aimed to investigate the association between EDs and career aspirations in middle adolescence. The participants were 147 adolescents diagnosed with EDs. Participants reported on their future career aspirations, and these were coded according to the International Standard Classification of Education of 1997. Of the participants, 83 adolescents were followed up longitudinally, and their aspirations were reassessed and compared for stability across the two assessments. Moreover, participants' career aspirations were compared to those of healthy (non-ED) best-friend controls. Health-related and social-behavioral science careers were chosen significantly more by adolescents with an ED as compared to their non-ED counterparts. For adolescents with an ED, career choices were consistent across reassessments. These findings suggest that adolescents with an ED gravitate toward careers associated with their pathology, namely, both facets of their mind-body pathology. This finding may indicate restricted identity development for adolescents with an ED. Suggestions for treatments protocols to include identity exploration are discussed.

    Chen, Hao; Zhu, Sheng; Chen, Liang-Biao

    2005-03-01

    In 1970's, Ohno proposed that primordial proteins might evolve from periodic amplification of oligopeptides. Internal repeating segments in proteins may play important roles in functional evolution of proteins. In this study,a new method was designed to extract internal repeating segments from proteomes of 8 modern species belong to eukaryota, bacteria and archaea, respectively. The repeating patterns and the frequencies within proteomes of each kingdom were analyzed by matrix plot. Simple repeat segments were found in eukaryotic proteins with high frequencies,but were much lower in bacteria and none in archaea. Further analysis showed that, the biased usage of amino acids in the internal repeating segments was positively related to the frequencies of individual amino acids in the proteome of a given species. The correlation coefficient was up to 0.95 in prokaryota, with the eukaryota to be lower. The high frequency of simple repeat sequences in eukaryotic proteomes, as well as the disparate relationships of amino acid compositions between the internal repeating segments and their haboring eukaryotic proteomes imply that the fast evolution of simple repeat sequences could be one force that generates the high complexity of eukarytic proteomes.

    A very large grey area exists between translational stem cell research and applications that comply with the ideals of randomised control trials and good laboratory and clinical practice and what is often referred to as snake-oil trade. We identify a discrepancy between international research and ethics regulation and the ways in which regulatory instruments in the stem cell field are developed in practice. We examine this discrepancy using the notion of 'national home-keeping', referring to the way governments articulate international standards and regulation with conflicting demands on local players at home. Identifying particular dimensions of regulatory tools - authority, permissions, space and acceleration - as crucial to national home-keeping in Asia, Europe and the USA, we show how local regulation works to enable development of the field, notwithstanding international (i.e. principally 'western') regulation. Triangulating regulation with empirical data and archival research between 2012 and 2015 has helped us to shed light on how countries and organisations adapt and resist internationally dominant regulation through the manipulation of regulatory tools (contingent upon country size, the state's ability to accumulate resources, healthcare demands, established traditions of scientific governance, and economic and scientific ambitions).

  4. Comparing Cross-Cultural Dimensions of the Experiences of International Tourists in Vietnam

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available Vietnam’s location in South East Asia places it well to benefit from tourism growth trends regionally and globally. It appeals to international tourists because of its long history, its culture and its unique customs and habits. Vietnam is experiencing rapid international tourism growth of visitors from different cultural backgrounds which places pressure on tourism service providers. If development is to be well managed, tourism professionals will need to broaden their understanding of both Western and Asian visitors, and managers need to encourage an atmosphere of familiarity and comfort amongst tourist groups, thus enhancing visitor satisfaction. However, appealing to diverse tourists markets is difficult because the needs of visitors are culturally determined and complex. Despite the importance of tourism for Vietnam, no research has attempted to measure tourist satisfaction in a cross-cultural context. In the present paper, a conceptual framework is proposed to explain the determinants of satisfaction amongst international tourists from different cultures when holidaying in Vietnam. In developing the proposed model, a review is undertaken of the concepts of culture, rules of behaviour, tourist perception and satisfaction. A range of factors are take into account including internal factors (such as cultural values, rules of behaviour, socio-demographics, behavioural and other travel characteristics and external factors including tourist perceptions of their hosts and of products and services.

    2016-03-01

    We diagnosed 10 Galeazzi-equivalent injuries. We report the radiological and clinical results at the end of growth in adolescents, including the results of ulnar lengthening. This study included 10 Galeazzi-equivalent injuries (seven patients requiring open reduction and three requiring closed reduction for ulnar lesions) seen since 2004. The periosteum was entrapped around the fractured physis in five patients and the extensor carpi ulnaris to the periosteum was interposed in two patients. Among the seven patients, ulnar lengthening was performed in only three patients. Ulnar variances at the time of the lengthening were -6, -6, and -5 mm. Gradual lengthening was performed. Radiologic abnormalities, including the ulnar variances, were investigated at the end of growth. In addition, pain scores, the range of wrist motion, and grip strength were evaluated and compared with nonlengthened ulnas. The mean age of the patients at the final follow-up was 19.7 years, and the mean total follow-up period was 6 years. The final ulnar variances were -5, -5, -3, and 0 mm in four patients with nonlengthened ulnas among the seven patients. Three patients with lengthened ulnas showed final neutral variances. In four nonlengthened ulnas, three ulnas bowed to the radial side and two ulnar heads had an inclined and deformed shape. Joint mismatch of the distal radioulnar joint surface was found in one patient with lengthened and one with nonlengthened ulnas. Three patients with nonlengthened ulnas showed decreased range of wrist motions. Comparison of contralateral grip strength indicated a significant difference between patients with or without lengthened ulnas. Long-term follow-up after Galeazzi-equivalent injuries may be essential to check for premature epiphyseal closure, length discrepancies, or joint incongruency. A procedure for a shortened ulna could be needed; however, the appropriate time and degree of lengthening remain to be investigated.

  9. Adoptive parenting and attachment: association of the Internal Working Models between adoptive mothers and their late-adopted children during adolescence

    2015-09-01

    Full Text Available Introduction. Recent literature has shown that the good outcome of adoption would mostly depend on the quality of adoptive parenting, which is strongly associated with the security of parental internal working models (IWMs of attachment. Specifically, attachment states-of-mind of adoptive mothers classified as free and autonomous and without lack of resolution of loss or trauma could represent a good protective factor for adopted children previously maltreated and neglected. While most research on adoptive families has focused on pre-school and school-aged children, the aim of this study was to assess the concordance of IWMs of attachment in adoptive dyads during adolescence.Method. Our pilot-study involved 76 participants: 30 adoptive mothers (mean age=51.5±4.3, and their 46 late-adopted adolescents (mean age = 13.9 ± 1.6, who were all aged four to nine years old at time of adoption (M = 6.3 ± 1.5. Attachment representations of adopted adolescents were assessed by the Friend and Family Interview (FFI, while adoptive mothers’ state-of-mind with respect to attachment was classified by the Adult Attachment Interview (AAI. Adolescents’ verbal intelligence was controlled.Results. Late-adopted adolescents were classified as follows: 67% secure, 26% dismissing and 7% preoccupied in the FFI, while their adoptive mothers’ AAI classifications were 70% free-autonomous, 7% dismissing, and 23% unresolved. We found a significant concordance of 70% (32 dyads between the secure-insecure FFI and AAI classifications. Specifically adoptive mothers with high coherence of transcript and low unresolved loss tend to have late-adopted children with high secure attachment, even if the adolescents’ verbal intelligence made a significant contribution to this prediction.Discussion. Our results provides an empirical contribution to the literature concerning the concordance of attachment in adoptive dyads, highlighting the beneficial impact of highly coherent

  10. The quality of life after a femoral neck fracture in elderly patients: a comparative study between internal fixation and arthroplasties

    2017-01-01

    Full Text Available Introduction: The femoral neck fracture is a frequent pathology in the elderly population, with about of 100,000 cases per year in Brazil. The surgical treatment by internal fixation or arthroplastic hip replacement is advocated today. The non-surgical treatment is reserved for cases of exception. Objective: To compare the quality of patient postoperative life treated for femoral neck fracture by two different techniques: hip arthroplasty and internal fixation. Methods: Through the SF-36 questionnaire, we study the quality of life of 60 patients with more than 65 years, treated between 2004 and 2012 in our service. Half of the patients was submitted to internal fixation and the other half to the arthroplastic replacement. Results: Higher averages in the large majority of the parameters of the questionnaire were obtained by the group which was carried out by internal fixation, but without statistical significance in most of these differences. Some international reports indicate that patients who have suffered a fracture of the femoral neck and were treated with internal fixation may recover the quality of life they had before the fracture. Paradoxically, there is a growing trend among orthopedic surgeons to perform a hip replacement surgery in these cases. Conclusion: Further studies are needed to define which is the best surgical treatment option.

    Although scale-up of antiretroviral therapy (ART) since 2005 has contributed to declines of about 30% in the global annual number of human immunodeficiency (HIV)-related deaths and declines in global HIV incidence, estimated annual HIV-related deaths among adolescents have increased by about 50% and estimated adolescent HIV incidence has been relatively stable. In 2012, an estimated 2,500 (40%) of all 6,300 daily new HIV infections occurred among persons aged 15-24 years. Difficulty enrolling adolescents and young adults in ART and high rates of loss to follow-up (LTFU) after ART initiation might be contributing to mortality and HIV incidence in this age group, but data are limited. To evaluate age-related ART retention challenges, data from retrospective cohort studies conducted in seven African countries among 16,421 patients, aged ≥15 years at enrollment, who initiated ART during 2004-2012 were analyzed. ART enrollment and outcome data were compared among three groups defined by age at enrollment: adolescents and young adults (aged 15-24 years), middle-aged adults (aged 25-49 years), and older adults (aged ≥50 years). Enrollees aged 15-24 years were predominantly female (81%-92%), commonly pregnant (3%-32% of females), unmarried (54%-73%), and, in four countries with employment data, unemployed (53%-86%). In comparison, older adults were more likely to be male (padolescents and young adults had higher LTFU rates in all seven countries, reaching statistical significance in three countries in crude and multivariable analyses. Evidence-based interventions to reduce LTFU for adolescent and young adult ART enrollees could help reduce mortality and HIV incidence in this age group.

    Self-esteem, generally regarded as an important indicator of adolescents' mental health, was assessed by a self-report questionnaire in a school sample of 593 subjects who had been assessed at 3 time points over 7 years between 11 and 25 years of age within the Zurich Psychology and Psychopathology Study (ZAPPS). Cross-lagged panel analyses of the longitudinal data from ZAPPS indicated that self-esteem was predictive of internalizing problems and had an impact on internalizing symptoms when the analyses were adjusted for coping behavior, efficiency of social networks, and impact of stressful life events. Self-esteem was also stable (r = .37-.60) within the observed age range, after controlling for prior levels of the predicted variables. The findings support the impact of self-esteem on mental health and indicate the importance of addressing self-esteem in prevention and intervention programs.

    2015-04-01

    There is limited research examining psychological correlates of a uniquely racialized experience of the model minority stereotype faced by Asian Americans. The present study examined the factor structure and fit of the only published measure of the internalization of the model minority myth, the Internalization of the Model Minority Myth Measure (IM-4; Yoo et al., 2010), with a sample of 155 Asian American high school adolescents. We also examined the link between internalization of the model minority myth types (i.e., myth associated with achievement and myth associated with unrestricted mobility) and psychological adjustment (i.e., affective distress, somatic distress, performance difficulty, academic expectations stress), and the potential moderating effect of academic performance (cumulative grade point average). Results suggested the 2-factor model of the IM-4 had an acceptable fit to the data and supported the factor structure using confirmatory factor analyses. Internalizing the model minority myth of achievement related positively to academic expectations stress; however, internalizing the model minority myth of unrestricted mobility related negatively to academic expectations stress, both controlling for gender and academic performance. Finally, academic performance moderated the model minority myth associated with unrestricted mobility and affective distress link and the model minority myth associated with achievement and performance difficulty link. These findings highlight the complex ways in which the model minority myth relates to psychological outcomes.

    2012-12-01

    Full Text Available Advertising today has conquered national boundaries, reaching consumers everywhere; however, local commercials retain their cultural background, combining global and local features. This is the new “glocalization” phenomenon, or the specificity of globalization. During the past two decades, Romanian advertising developed spectacularly, making up for the time it was forbidden. Life-styles, consumer insight, economy and market dynamics changed the relationship between global and local advertising. Today, national advertising promotes surviving pre-Revolution brands, new, post-1990 brands, and international brands adapted to the local market. This chapter analyzes the local and global features of Romanian TV commercials for national and international brands according to the following criteria: positioning, visual/verbal identity, social/cultural background.

    2007-10-01

    Relations between various values of the internal friction (tgdelta, Q(-1), Q(-1*), and Lambda/pi) measured by free decay and forced vibration are analyzed systemically based on a fundamental mechanical model in this paper. Additionally, relations between various natural frequencies, such as vibration frequency of free decay omega(FD), displacement-resonant frequency of forced vibration omega(d), and velocity-resonant frequency of forced vibration omega(0) are calculated. Moreover, measurement of natural frequencies of a copper specimen of 99.9% purity has been made to demonstrate the relation between the measured natural frequencies of the system by forced vibration and free decay. These results are of importance for not only more accurate measurement of the elastic modulus of materials but also the data conversion between different internal friction measurements.

    1990-07-01

    Clean coal technologies (CCTs) are being demonstrated in research and development programs under public and private sponsorship. Many of these technologies could be marketed internationally. To explore the scope of these international opportunities and to match particular technologies with markets appearing to have high potential, a study was undertaken that focused on seven representative countries: Italy, Japan, Morocco, Turkey, Pakistan, the Peoples' Republic of China, and Poland. The results suggest that there are international markets for CCTs and that these technologies can be cost competitive with more conventional alternatives. The identified markets include construction of new plants and refurbishment of existing ones, especially when decision makers want to decrease dependence on imported oil. This report describes potential international market niches for U.S. CCTs and discusses the status and implications of ongoing CCT demonstration activities. Twelve technologies were selected as representative of technologies under development for use in new or refurbished industrial or electric utility applications. Included are the following: Two generic precombustion technologies: two-stage froth-flotation coal beneficiation and coal-water mixtures (CWMs); Four combustion technologies: slagging combustors, integrated-gasification combined-cycle (IGCC) systems, atmospheric fluidized-bed combustors (AFBCs), and pressurized fluidized-bed combustors (PFBCs); and Six postcombustion technologies: limestone-injection multistage burner (LIMB) systems, gas-reburning sorbent-injection (GRSI) systems, dual-alkali flue-gas desulfurization (FGD), spray-dryer FGD, the NOXSO process, and selective catalytic reduction (SCR) systems. Major chapters of this report have been processed separately for inclusion on the data base.

    The burgeoning immigrant population in major immigrant-receiving countries in North America and Europe has necessitated researchers and policymakers in these countries to examine the academic success of children of immigration and the factors contributing to their academic success. However, there is sparse research on the academic trajectories of children of immigration in other continents, such as Asia. Hence, the purpose of the present study was to examine first- and second-generation immigrant adolescents' mathematics achievement and dispositions towards mathematics in comparison to their native peers in one of the Middle Eastern countries in Asia, Qatar. The results of the study indicated that both first- and second-generation immigrant adolescents tended to have higher mathematics achievement, intrinsic motivation to learn mathematics, instrumental motivation to learn mathematics, mathematics self-efficacy, and mathematics self-concept than did their native counterparts. Moreover, immigrant adolescents tended to have lower mathematics anxiety than did their native peers. The study also revealed significant differences between first- and second-generation immigrant adolescents with respect to their mathematics achievement and dispositions towards mathematics.

    Against the backdrop of demographic change and economic reconfiguration, recruiting international students, especially those at tertiary level, has drawn growing attention from advanced economies as part of a broad strategy to manage highly skilled migration. This comparative study focuses on three English speaking countries receiving international students: Canada, the United States, and the United Kingdom. International student policies, in particular entry and immigration regulations, and the trends in student mobility since the late 1990s are examined drawing on secondary data. By exploring the issue from the political economy perspectives, this study identifies distinct national strategies for managing student mobility, determines key factors shaping the environment of student migration in each nation, and addresses the deficiency of human capital theory in the analysis of global competition for high skills.

    Full Text Available The propagation of utilization of arbitration as a method of dispute resolution depends on the public confidence in the method. In this regard, the independence of arbitrators and their impartiality are necessary conditions for the realization of such confidence. Independence and impartiality of arbitrators ensure a fair trial in arbitration and the lack of aforementioned features makes it impossible to trust the fairness of the dispute settlement process and its result. The importance of confidence in the health of the dispute settlement system is to the extent that many international instruments have frequently emphasised on the necessity of the two above-mentioned features. In the recent decade, contemporaneous with the incredible development of arbitration, the debate over independence and impartiality of arbitrator has become important and controversial because neither national laws nor international provisions provide a clear difinition of the said concepts. This article set out to explain the exact point that the independence and impartiality are distinct concepts and are not interchangeable with each other; Independence is concerned with the relationships between the arbitrator and disputing parties, while impartiality considers the arbitrator's conduct over the equal treatment with the parties. The aforesaid distinction includes such a legal effect that each of these two concepts shall be considered as an autonomous and separate cause for challenging arbitrators.

    Full Text Available Anterior cruciate ligament (ACL surgery is being increasingly performed in the adolescent population. Computer navigation offers a reliable way to quantitatively measure knee stability during ACL reconstruction. A retrospective review of all adolescent patients (<18 years old who underwent computer-assisted primary single bundle ACL reconstruction by a single surgeon from 2007 to 2012 was performed. The average age was 15.8 years (SD 3.3. Female adolescents were found to have higher internal rotation than male adolescents both pre- (25.6° vs 21.7°, P=0.026 and post-reconstruction (20.1° vs 15.1°, P=0.005. Compared to adults, adolescents demonstrated significantly higher internal rotation both pre- (23.3° vs 21.5°, P=0.047 and post-reconstruction (17.1° vs 14.4°, P=0.003. They also had higher total rotation both pre- (40.9° vs 38.4°, P=0.02 and post-reconstruction when compared to adults (31.56° vs 28.67°, P=0.005. In adolescent patients, anterior translation was corrected more than rotation. Females had higher pre- and residual post-reconstruction internal rotation compared to males. When compared to adults, adolescents had increased internal rotation and total rotation both pre- and post-reconstruction.

    Despite accumulated experimental evidence of the negative effects of exposure to media-idealized images, the degree to which body image, and eating related disturbances are caused by media portrayals of gendered beauty ideals remains controversial. On the basis of the most up-to-date meta-analysis of experimental studies indicating that media-idealized images have the most harmful and substantial impact on vulnerable individuals regardless of gender (i.e., "internalizers" and "self-objectifiers"), the current longitudinal study examined the direct and mediated links posited in objectification theory among media-ideal internalization, self-objectification, shame and anxiety surrounding the body and appearance, dietary restraint, and binge eating. Data collected from 685 adolescents aged between 14 and 15 at baseline (47 % males), who were interviewed and completed standardized measures annually over a 3-year period, were analyzed using a structural equation modeling approach. Results indicated that media-ideal internalization predicted later thinking and scrutinizing of one's body from an external observer's standpoint (or self-objectification), which then predicted later negative emotional experiences related to one's body and appearance. In turn, these negative emotional experiences predicted subsequent dietary restraint and binge eating, and each of these core features of eating disorders influenced each other. Differences in the strength of these associations across gender were not observed, and all indirect effects were significant. The study provides valuable information about how the cultural values embodied by gendered beauty ideals negatively influence adolescents' feelings, thoughts and behaviors regarding their own body, and on the complex processes involved in disordered eating. Practical implications are discussed.

    Full Text Available In this study, the internal reproductive organs of Grapholita molesta males and females are described, illustrated and measured, considering virgin individuals of one and eight days of age and mated individuals of eight days. In females, the ovaries, lateral oviducts, common oviduct, bursa copulatrix and seminal receptacle were evaluated. The most evident alterations were observed in the ovaries, which were significantly larger in eight-day-old virgin females, and also in the bursa copulatrix of mated specimens. In males, we observed one pair of fused testes, paired vas deferens, seminal vesicles, duplex ejaculatory ducts and glands, and simplex ejaculatory duct and aedeagus. The testis of eight-day-old specimens, both virgin and mated, were significantly smaller than they were in one-day-old virgin males.

    There are striking disparities in the academic achievement of American youth, with Latino students being a particularly vulnerable population. Adolescents' academic expectations have been shown to predict educational outcomes, and thus are an important factor in understanding educational disparities. This article examines racial/ethnic differences in the future expectations of adolescents, with a particular focus on how expectations about higher education may differ in frequency and meaning for Latino youth. Participants included 375 urban ninth-grade students (49 % Latino, 23 % White, 22 % Black, and 6 % other; 51 % female) who gave written descriptions of how they pictured their lives in 5 years. Responses were subsequently coded for content and themes. Results demonstrate that Latino youth were less likely to picture themselves attending college when compared to Black and White youth, and more likely to hold social goals, such as starting their own family. Ethnic/racial differences also were found in the themes present in responses, with Latino and Black students more likely than White students to describe individuation and materialistic goals, and to give more unrealistic responses. For Latino youth only, higher education goals were associated significantly with individuation themes. In addition, for Latino youth, adolescents who wished to pursue higher education reported more depressive symptoms and emotional distress than those who did not picture going to college, whereas the opposite pattern was evident for Black and White youth. These differences may reflect cultural values, such as familismo. Practice implications include the importance of culturally tailoring programs aimed at promoting higher education.

    Full Text Available Introduction: Globalization has favored intra-European Commission (EC and extra-EC migration to Spain. One of the most numerous cultural groups that have settled in the southern Spain is from Romania. Coexistence, especially in schools, has made us become interested in knowing the eating habits at breakfast of Romanian and Spanish populations. Numerous studies show that the food intake at breakfast, mostly made before leaving home, has an incidence on the physic wellbeing of adolescent throughout the day. The processes of acculturation are also inseparable from the eating habits, health and life, that maintain the migrant teenagers. Breakfast is analyzed as one of the habits more associated with diet quality; paradoxically, one of the findings of our study, many adolescents do not take a proper breakfast every day.

    Full Text Available Abstract Background The literature on simulated or standardized patient (SP methodology is expanding. However, at the level of the program, there are several gaps in the literature. We seek to fill this gap through documenting experiences from four programs in Australia, Canada, Switzerland and the United Kingdom. We focused on challenges in SP methodology, faculty, organisational structure and quality assurance. Methods We used a multiple case study method with cross-case synthesis. Over eighteen months during a series of informal and formal interactions (focused meetings and conference presentations we documented key characteristics of programs and drew on secondary document sources. Results Although programs shared challenges in SP methodology they also experienced differences. Key challenges common to programs included systematic quality assurance and the opportunity for research. There were differences in the terminology used to describe SPs, in their recruitment and training. Other differences reflected local conditions and demands in organisational structure, funding relationships with the host institution and national trends, especially in assessments. Conclusion This international case study reveals similarities and differences in SP methodology. Programs were highly contextualised and have emerged in response to local, institutional, profession/discipline and national conditions. Broader trends in healthcare education have also influenced development. Each of the programs experienced challenges in the same themes but the nature of the challenges often varied widely.

    Full Text Available The terms on which the integration of new generations of immigrants into Portuguese and Spanish societies happens will have a decisive influence in the future of both countries. Therefore, promoting their health, well-being, and psychosocial adaptation is a matter of strategic interest. This paper analyses psychosocial factors associated with well-being and psychological adjustment on a sample of 108 adolescents (55 males and 53 females, children of immigrants from Huelva (Spain and Algarve (Portugal, aged between 10 and 17 years. Adolescents were assessed for demographic characteristics and perceived well-being. We used the "KIDSCREEN-5", a self-report questionnaire that yields detailed profile information for children aged 8 to 18 years for the following ten dimensions: Physical well-being, Psychological well-being, Moods and emotions, Self-perception, Autonomy, Parental relationships and home life, Financial resources, Social support and peers, School environment, and Social acceptance (Bullying. Overall, significant differences were found between the Spanish and Portuguese samples on physical well-being, psychological well-being, mood, financial resources and social acceptance (bullying. Boys perceived themselves as having a better physical well-being than girls. Mothers' educational level was associated with psychological well-being and mood. Also, results suggested that residence location and other socio-demographical variables were not associated with the adolescents' well-being and psychological adjustment.

    2016-10-01

    Youth incarceration is an international public health concern among developed and developing countries. Worldwide, youth are held in incarceration, detention, and other secure settings that are inappropriate for their age and developmental stages, jeopardizing their prosocial development, and reintegration into society. Youth incarceration lacks evidence and cost-effectiveness. The well-being of youth is a key indicator of the welfare of families, communities, and society at large; therefore, the Society for Adolescent Health and Medicine (SAHM) supports a paradigm shift in the role of the justice system as it relates to treatment of youth. SAHM recommends justice systems focus greater attention and resources on identifying and reducing the antecedents of high-risk and criminal behaviors, recognizing the rights and freedom of young persons, and prioritizing the well-being of youth over punitive measures that may harm and disrupt healthy adolescent development. SAHM supports the following positions: (1) incarceration is a last option for selected offenders who have committed the most serious violent crimes and are unable to remain safely in the community; (2) youth justice policies, programs, and practices affecting youth be evidence based and trauma informed; (3) youth justice policies, programs, and practices must incorporate research and ongoing program evaluation; (4) youth justice policies shall protect the privacy and dignity of children younger than 18 years; and (5) health care professionals and media will promote positive portrayals of youth in healthy relationships within their communities and reduce representations and images of youth that are negative, violent, deviant, and threatening.

    2009-09-01

    Full Text Available Since 2000, a number of parliaments and governments have introduced electronic petitions systems (e-petitions. Compared to most other means of e-participation made available by public institutions, e-petitions have moved beyond the experimental stage and are characterized by a high level of institutionalization and procedural maturity. Hence, the field of e-petitioning is particularly promising if the relationship between public institutions and Internet-based participation channels is to be better understood. Based on empirical data generated in the research project "Public electronic petitions and civic involvement" conducted on behalf of the German Bundestag, the article undertakes an analysis of the e-petition systems of the Scottish Parliament, the Parliament of Queensland, the Bundestag and the Norwegian Municipalities in comparative perspective. Apart from presenting the systems’ main technical and procedural features and selected user statistics, the article attempts to explain the high attractiveness of e-petitions for parliaments and governments.

We mainly focus our presentation on exploring all the possibilities that each type of database offers us, in the case that the data, which has to be stored, cannot or is not wanted to be normalized. This is a scenario most often found in production when, for the application that is being developed we are extracting unstructured data from social networks or all kinds of different channels that the user might have. The comparative study is based on the creation of a benchmark application developed in C# using Visual Studio 2013, which accesses databases created beforehand with proper optimizations that will be described.

    Full Text Available In today's world, human made familiar with a space called cyberspace which its feature is distinct in the physical and material world. Productivity of this space is always dependent on information technological progress and electronic communications and human forced to the use of its universal and general of this space in all the political, economic, social, cultural and military dimension. In this regard, some norms should be established, some deals should be made and prevented about abnormal conditions based on the unique features of cyberspace . In this context, our country has not been joined to none of the international conventions related to the cybercrime and the judiciary and security forces has been faced with difficulties to prevent of these crimes in practicedue to the current vacuum in domestic law. Accordingly, in the first instance, point of view of legislator has been considered in strengthening the legally binding texts in prevention of cybercrime. In this regard and in dimension of non-criminal prevention, primarily, looking at situational prevention is necessary. Certainly, the physical presence of institutions for prevention will have an important role in the prevention of these crimes in cases where cybercrimecarry out by entry of unauthorized users to acomputer site. Police can be an important role in prevention process byusing the powerful software and caring of mentioned space .In the second place, public education and provide the specific training to individuals and organizations that are likely to be at risk of cyber crime and identification of caller ID belongs to these measures, should be considered in the realm of social protection.

    The purpose of this study was to compare movement pattern, fatigue development, and heart rate (HR) for top-class elite female players when playing international (INT) vs. domestic league games (DOM). Video-based time-motion analyses and HR recordings were performed on 17 players during INT and DOM. The distances covered in high-intensity running (HIR) and sprinting were longer (p game types, the amount of HIR was reduced by 24-27% (p game. The midfielders covered longer (p game and in the most intense 5-minute period of the games, whereas no differences were observed between the game types for defenders. No difference in the HR response was found between INT and DOM. In conclusion, more HIR and sprinting occur in international compared with domestic games, which may affect the fatigue development for players in physically demanding roles. Thus, our results are important to coaches to prepare players to meet the challenges of international soccer games and show that the ability to perform intense intermittent exercise should be trained regularly in elite female players.

    Full Text Available OBJECTIVE: The aim of this study is to find out if an ultrasound technique has advantages over the conventional landmark technique. METHODS: This is a prospective randomized comparative study on 120 patients requiring central venous cannulation of the right internal jugular vein. The study comprised of two groups: ultrasound and landmark groups, each consisting of 60 patients. The outcome measures were compared between the groups. RESULTS: Cannulation of the internal jugular vein was successful in 58 patients in the ultrasound group and in 53 in the landmark group. The number of attempts was 1.5 (1 - 3 and 2 (1 - 3 in the ultrasound and landmark group respectively (p = 0.001. The time taken for the successful cannulation was 4.9 +/- 1.7 minutes in the ultrasound approach and 8.0 +/- 2.8 minutes in the landmark approach (p = 0.00. The internal jugular vein diameter in the supine position was 11.2 +/- 1.5 mm which increased to 15.04 +/- 1.5 mm with a 15 degrees head-down position in the USG group (p = 0.001. The first attempt success rate was 39/60 (63% in the ultrasound group and 19/60 (32% with the landmark technique. The seven (12% failure cases in the landmark group were rescued by the ultrasound technique. Inadvertent carotid artery puncture occurred in 2/60 (3% and 6/60 (10% of patients in the ultrasound and land mark group respectively. CONCLUSIONS: Ultrasound improves success rate, minimizes cannulation time and complications during internal jugular vein cannulation. It can be employed as a rescue technique in cases of a failed landmark technique. Keywords:cannulation, central, landmark, technique, ultrasound.

  6. International collaborative project to compare and track the nutritional composition of fast foods

    2012-07-01

    Full Text Available Abstract Background Chronic diseases are the leading cause of premature death and disability in the world with over-nutrition a primary cause of diet-related ill health. Excess quantities of energy, saturated fat, sugar and salt derived from fast foods contribute importantly to this disease burden. Our objective is to collate and compare nutrient composition data for fast foods as a means of supporting improvements in product formulation. Methods/design Surveys of fast foods will be done in each participating country each year. Information on the nutrient composition for each product will be sought either through direct chemical analysis, from fast food companies, in-store materials or from company websites. Foods will be categorized into major groups for the primary analyses which will compare mean levels of saturated fat, sugar, sodium, energy and serving size at baseline and over time. Countries currently involved include Australia, New Zealand, France, UK, USA, India, Spain, China and Canada, with more anticipated to follow. Discussion This collaborative approach to the collation and sharing of data will enable low-cost tracking of fast food composition around the world. This project represents a significant step forward in the objective and transparent monitoring of industry and government commitments to improve the quality of fast foods.

  7. Comparative international analysis of radiofrequency exposure surveys of mobile communication radio base stations.

    2012-01-01

    This paper presents analyses of data from surveys of radio base stations in 23 countries across five continents from the year 2000 onward and includes over 173,000 individual data points. The research compared the results of the national surveys, investigated chronological trends and compared exposures by technology. The key findings from this data are that irrespective of country, the year and cellular technology, exposures to radio signals at ground level were only a small fraction of the relevant human exposure standards. Importantly, there has been no significant increase in exposure levels since the widespread introduction of 3G mobile services, which should be reassuring for policy makers and negate the need for post-installation measurements at ground level for compliance purposes. There may be areas close to antennas where compliance levels could be exceeded. Future potential work includes extending the study to additional countries, development of cumulative exposure distributions and investigating the possibility of linking exposure measurements to population statistics to assess the distribution of exposure levels relative to population percentiles.

    Full Text Available Background Headaches are common problems in adults, adolescents, and children. Headaches impact a child’s life, their family life, and even society. An assessment of quality of life in adolescents with primary headaches may help to determine actions necessary to improve the quality of life of these patients. Objective To assess the quality of life of adolescents with primary headaches compared to healthy adolescents. Methods We conducted a cross-sectional study in December 2009 on adolescents aged 13 to 18 years. The headache group consisted of children with primary headaches according to the International Classification of Headache Disorders and the control group consisted of healthy adolescents. Subjects were selected by consecutive sampling, with 75 subjects in each group. Subjects filled the Pediatric Quality of Life Inventory version 4.0 (PedsQL 4.0 questionnaire. Results The mean PedsQL total score was significantly lower in the headache group than in the control group [175.7 vs. 392.2, respectively, (95%CI of differences -28.1 to -219.3, P = 0.001]. However, out of 23 items in the questionnaire, 9 were not significantly different between the headache and control groups. Conclusions Primary headaches in adolescents is associated with lower quality of life. Most quality of life domains scores are significantly lower in adolescents with primary headaches compared to those without primary headaches. [Paediatr Indones. 2013;53:350-4.].

    In the past 17 years neonatal mortality survey has provided important data on the trends in deaths of all live born infants born in Southern Ireland who are greater than 500 g birth weight and who die within the first 28 days of life. The aims of this study were to report neonatal mortality data for Southern Ireland for 2004, to examine trends in neonatal mortality over the past 17 years and compare Irish Neonatal Mortality rates to other countries around the world. The neonatal mortality rate for 2004 was 2.9\\/1000 with a corrected NMR of 1.9\\/1000. The response rate to the survey was 100%. Prematurity is now the leading cause of neonatal mortality representing a change from previous years. Deaths related to asphyxia have remained largely unchanged. When compared to international figures Ireland compares favourably to other countries around the world.

  10. COMPARATIVE INTERNATIONAL PERSPECTIVES ON MARKET-ORIENTED MODELS OF CORPORATE GOVERNANCE

    2010-07-01

    Full Text Available The study of corporate governance requires not only the knowledge of economic, financial, managerial and sociological mechanisms and norms, but it must also incorporate an ethical dimension, while remaining aware of the demands of various stakeholders. The interest towards good governance practice is very present in the company laws of many countries. National differences may lead to specific attributes derived from the meaning that is given to the role of competition and market dispersion of capital. Based on a research consisting of a critical and comparative perspective, the present contribution is dominated by qualitative and mixed methods. In conclusion, it can be said that a market-oriented corporate governance model, though not part of the European Union’s convergence process, may very well respond to the increasing importance of investors’ rights and to the gradual evolution of corporate responsibilities, beyond the national context, with the aim of ensuring market liberalization.

    2001-10-01

    Teacher cohorts in England and China received special training in techniques for teaching higher-level critical and creative cognitive strategies to deaf learners. Both cohorts implemented the strategies in the classroom at least twice weekly for 6 months. Measures included Raven's Standard Progressive Matrices (1959), a systematic observation checklist for cognitive behaviors (Martin & Craft, 1998), and critical and creative problem situations to which students had to respond. Results were compared with those from a study of similar learners in the United States (Martin & Jonas, 1985), and little difference was found. Students in all three countries improved in reasoning, devising real-world problem solutions involving critical thinking (but not creative thinking), using cognitive vocabulary in the classroom, and expressing others' viewpoints. Postintervention focus groups showed teachers in China used a more invariant sequence in teaching the cognitive strategies, but teachers in all three countries experienced similar expansion in cognitive terminology and self-perceptions as teachers of problem solving.

    It is of great signif icance to conduct an international comparative study on China’s and other countries’ urbanization by taking the concept of "scale" as a crucial study point. This paper puts forward that countries with an area over two million km2 or a GDP over 650 billion dollars are comparable with China. Accordingly, there are 24 such countries in the world leading the global socio-economic development. For consisting of almost all types of countries, they can be considered as basic references for international comparative studies on China’s urbanization. Based on the relationship between urbanization and economic levels, the 24 countries can be divided into three tiers. The fi rst tier countries are mainly developed countries at high urbanization and economic levels; the second tier countries are later starters yet urbanized at a rapid speed, thus have fallen into the "middle-income trap" because of an imbalanced urbanization and economic development; the third tier countries including China and India are still in the starting phase of urbanization, and the key to their future development is a steady economic growth and a balanced urbanization and economic development.

    2016-01-01

    Background Reports of food-related incidents, such as cows infected with bovine spongiform encephalopathy (2001) and the Fukushima nuclear accident (2011), engendered significant fear among Japanese consumers and led to multiple farmer suicides, even when no actual health damage occurred. The growing availability of genetically modified (GM) food is occurring against this backdrop of concern about food safety. Consumers need information to assess risk and make informed purchasing decisions. However, we lack a clear picture of Japanese consumer perceptions of GM food. Objective This study aims to understand Japanese consumer perceptions of GM food for risk communication. Consumer perceptions of GM food were compared among 4 nations. Methods A Web-based survey was conducted in Japan, the United States, the United Kingdom, and France. Participants were asked about demographics, fear of health hazards, resistance to GM and breeding-improved products, perception of GM technology and products, and willingness to pay. Multiple linear regression analyses were conducted, as were t tests on dichotomous variables, and 1-way analysis of variance and post hoc tests. Results Of 1812 individuals who agreed to participate, 1705 (94%) responded: 457 from Japan and 416 each from France, the United States, and the United Kingdom. The male/female and age group ratios were all about even. Some resistance to GM food was seen in all countries in this study. France showed the strongest resistance (Pfood. Japan showed stronger fear of food hazards than other nations (Pfood (Pconsumers in nations other than Japan would accept GM food if it were appropriately explained, they were provided with scientific data supporting its safety, and they understood that all food carries some risk. However, Japanese consumers tended to accept GM technology but rejected its application to food (Pfood, consumers in Japan required a discount of 30% compared with about 20% in other nations.

    Full Text Available The main objective was to study the personality of the volleyball players of India. All the players of Indian team and the players of Brazil team, who came for FIVB Men Volleyball World Championship held at Pune in August 2009, were selected for the study. They were administered the Cattell’s 16 PF questionnaire. The results wereanalyzed with the help of ‘t’ test which showed that there are significant differences found between Indian volleyball players and Brazilian Volleyball players on seven factors but not on nine factors of 16 PF Questionnaire. Indian players scored high on factor ‘F’, factor ‘I’ and factor ‘M’ whereas Brazilian players have scored high on factor ‘B’, factor ‘G’, factor ‘H’ and factor ‘L’. Indian players scored low on Factor B which means that they tend to be slow to learn and grasp and they were dull as compared with Brazilian team, and gives concrete and literal interpretation. This dullness simply represents poor functioning.

    Dara, Ajay; Sangamwar, Abhay T

    2015-01-01

    The article reported an in-depth comparative technology analysis of 1708 Anti-cancer patents from top 20 international universities and leading 10 Indian public funded organization and research institutes. The study segregated pioneer universities vs. technologies used in the field of Anticancer research at a level of drug discovery, development, diagnosis and treatment, which are illustrated in the form of novel substantive patent landscape maps. The reported competitive intelligent maps identified genetics, composition and synthetic compounds as dominating technologies; followed by natural extracts, combination and drug delivery systems as upcoming technologies. The least number of patents were reported by surgical apparatus, targeted therapy and animal models. In addition, the study analysed the key technologies followed by Indian universities in comparison to the international universities, to identify the overlooked technologies by the Indian public funded institutes. In an ever changing competitive world, it is essential for every university to have their own research plan and thrust areas; but at the same time, it is equally important for any organisation to have an idea of their competitor's research plan as well. So, the article suggested Indian institutes to focus on the latest emerging Anti-cancer technology trends, which are in practice by the international universities. Concurrently, this study may be a landmark indication for Indian public funded universities and institutes, calling for a U-turn from their traditional approaches.

  18. Analysis of English language textbooks in the light of English as an International Language (EIL: A comparative study

    Naji Meidani, Elham

    2013-01-01

    Full Text Available The global spread of the English language has not only resulted in more non-native speakers than native speakers (Crystal, 1997, but it has even put into question the ownership of the language (Widdowson, 1994; Brumfit, 1995. Therefore, English is recognized as an international language that does not belong to any particular country and is used for global, political, cultural and financial exchange. The following study aimed to find out to what extent English language textbooks demonstrate the international status of the language by comparing four different textbooks published in different years. To this purpose, the following criteria were taken into account: references to Inner Circle countries, references to Outer and Expanding Circle countries, non-native accents, dialogues in non-English speaking countries, place of home culture and famous people. The analysis revealed differences among the selected books with a gradual tendency towards more recognition of the international status of English. Finally, the results were discussed and some suggestions were made in the context of English language learning and teaching.

    2007-01-01

    Many substance use prevention programs directed at adolescents exist that have been developed by researchers in the United States and are intended to be used in school settings. Some of the problems associated with such programs are reviewed, including their accessibility, ease of use, copyright status, evaluation options, program scales, and ratings, together with an overall consideration of the factors and processes posited to be associated with substance use and non-use (posited "at-risk" and "protective" mechanisms). The authors contend that there is a great need to: (a) develop substance use prevention programs which are commercially available but are not protected by copyright, (b) assess empirically each component in a program separately, and (c) encourage funding bodies to be more active in supporting the production of manuals and evaluation instruments for substance use prevention programs directed at adolescents. We need more and better process evaluations that are also sensitive to both endogenous and exogenous forces in order to know the processes by which a successful prevention program achieves its effects, is prevented from doing so and which processes are irrelevant. A social competence framework might be used as both a goal and as a theoretical base to achieve a better understanding of the processes by which substance use prevention programs reach their effects.

    Research suggests that borderline personality disorder (BPD) can be diagnosed in adolescents and is marked by considerable heterogeneity. This study aimed to identify personality features characterizing adolescents with BPD and possible meaningful patterns of heterogeneity that could lead to personality subgroups. The authors analyzed data on 60 adolescents, ages 15 to 18 years, who met DSM criteria for a BPD diagnosis. The authors used latent class analysis (LCA) to identify subgroups based on the personality pattern scales from the Millon Adolescent Clinical Inventory (MACI). LCA indicated that the best-fitting solution was a two-class model, identifying two discrete subgroups of BPD adolescents that were described as internalizing and externalizing. The subgroups were then compared on clinical and sociodemographic variables, measures of personality dimensions, DSM BPD criteria, and perception of attachment styles. Adolescents with a BPD diagnosis constitute a heterogeneous group and vary meaningfully on personality features that can have clinical implications for treatment.

    Using an air quality model, two future urban scenarios induced by the construction of the new international airport for Mexico City are compared at a regional level. The air quality model couples the meteorology model MM5 and state-of-the-art photochemistry. The air quality comparison is made using metrics for the criterion gases selected for the study. From the two urban scenarios compared, the option for Tizayuca is moderately better than the option for Texcoco, because relative reductions in O3 and other photochemical pollutants are achieved over highly populated areas. Regardless of the site, the air quality for the central region of Mexico in the future will deteriorate. In the region of central Mexico, SO2 and NO2 will become important pollutants.

    2012-09-01

    Previous literature has demonstrated the separate contributions of parental attributions and adolescent attributions to psychosocial adjustment of adolescents with chronic illness. However, it is unknown whether parental attributions affect adolescents' mental health directly or indirectly by influencing the youths' attributional style. This study evaluated the direct and indirect (through adolescent attributions) effects of parental attributions on internalizing and externalizing problems of adolescents with chronic illness. Adolescents (N = 128; M = 14.7 years) diagnosed with cystic fibrosis or diabetes and their caregivers completed measures of attributional style and adolescent adjustment. Parents' optimistic attributions were associated with fewer adolescent internalizing and externalizing problems. These effects were partly mediated by adolescent attributions. These results suggest that targeting both adolescent and parent attributions may be important for improving adolescents' adjustment to a chronic illness.

    Full Text Available The social skills rating system (SSRS is used to assess social skills and competence in children and adolescents. While its characteristics based on United States samples (US are published, corresponding Australian figures are unavailable. Using a 4-week retest design, we examined the internal consistency, retest reliability and measurement error (ME of the SSRS secondary student form (SSF in a sample of Year 7 students (N = 187, from five randomly selected public schools in Perth, western Australia. Internal consistency (IC of the total scale and most subscale scores (except empathy on the frequency rating scale was adequate to permit independent use. On the importance rating scale, most IC estimates for girls fell below the benchmark. Test-retest estimates of the total scale and subscales were insufficient to permit reliable use. ME of the total scale score (frequency rating for boys was equivalent to the US estimate, while that for girls was lower than the US error. ME of the total scale score (importance rating was larger than the error using the frequency rating scale. The study finding supports the idea of using multiple informants (e.g. teacher and parent reports, not just student as recommended in the manual. Future research needs to substantiate the clinical meaningfulness of the MEs calculated in this study by corroborating them against the respective Minimum Clinically Important Difference (MCID.

    Full Text Available Background. Stents have become the treatment of choice for native aortic coarctation in adults and adolescents, but in pediatric patients insufficient data are currently available to identify the best therapeutic option. Methods. To compare the outcomes of pediatric and adolescent patients, we retrospectively evaluated early and long-term results of stenting for aortic coarctation in 34 patients divided into 2 groups (A and B composed, respectively, of 17 children (mean age 8.2±2.3, weight ≤30 kg and 17 adolescents (mean age 14.3±1.7, weight >30 kg. Results. No significant differences in outcome were found between groups immediately after the procedure. In all of our patients, peak systolic gradient pressure significantly decreased after stenting from 43.7±12 to 1.7±3.1 mmHg in group A and from 39.4±16.8 to 1.6±3 in group B (p<0.0001. We observed early and late adverse events in both groups: early femoral vessel injury or thrombosis was more frequent in younger patients, as well as restenosis due to vessel growth requiring stent redilatations, often complicated by stent fractures. Data from long-term follow-up showed that, in younger patients, stress-related hypertension was more frequent. Conclusions. The procedure was immediately safe and effective in both groups. Pediatric patients must be accurately selected before stenting because they could probably need reinterventions and stents could impact on their future therapeutic perspectives.

    This study possessed 2 aims: (a) to develop and validate a clinician-friendly measure of academic problem behavior that is relevant to the assessment of adolescents with attention deficit/hyperactivity disorder (ADHD) and (b) to better understand the cross-situational expression of academic problem behaviors displayed by these youth. Within a sample of 324 adolescents with the Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision diagnosed ADHD (age M = 13.07, SD = 1.47), parent, teacher, and adolescent self-report versions of the Adolescent Academic Problems Checklist (AAPC) were administered and compared. Item prevalence rates, factorial validity, interrater agreement, internal consistency, and concurrent validity were evaluated. Findings indicated the value of the parent and teacher AAPC as a psychometrically valid measure of academic problems in adolescents with ADHD. Parents and teachers offered unique perspectives on the academic functioning of adolescents with ADHD, indicating the complementary roles of these informants in the assessment process. According to parent and teacher reports, adolescents with ADHD displayed problematic academic behaviors in multiple daily tasks, with time management and planning deficits appearing most pervasive. Adolescents with ADHD display heterogeneous academic problems that warrant detailed assessment prior to treatment. As a result, the AAPC may be a useful tool for clinicians and school staff conducting targeted assessments with these youth.

In this article, we investigate the determinants of anti-gay attitudes among adolescents in two liberal democracies, Belgium (n = 6,330) and Canada (n = 3,334). The analysis indicates that hostile feelings toward LGBT rights are particularly widespread among boys, while the effects of socioeconomic status and parental education remain limited. Various religious denominations proved to have a strong and significant negative impact on tolerance, with especially high scores for Islam. Religious practice, too, contributes to a negative attitude toward LGBT rights. The consequences of these findings with regard to tolerance for gay rights among Islamic youth in Western democracies are discussed.

    Full Text Available BACKGROUND: We recently showed that in preschoolers risk factors for overweight show stronger associations with BMI in children with high BMI values. However, it is unclear whether these findings might also pertain to adolescents. METHODS: We extracted data on 3-10 year-old (n = 7,237 and 11-17 year-old (n = 5,986 children from a representative cross-sectional German health survey (KiGGS conducted between 2003 and 2006 and calculated quantile regression models for each age group. We used z-scores of children's body mass index (BMI as outcome variable and maternal BMI, maternal smoking in pregnancy, low parental socioeconomic status, exclusive formula-feeding and high TV viewing time as explanatory variables. RESULTS: In both age groups, the estimated effects of all risk factors except formula-feeding on BMI z-score were greatest for children with the highest BMI z-score. The median BMI z-score of 11-17 year-old children with high TV viewing time, for example, was 0.11 [95% CI: 0.03, 0.19] units higher than the median BMI z-score of teenage children with low TV viewing time. This risk factor was associated with an average difference of 0.18 [0.06, 0.30] units at the 90(th percentile of BMI z-score and of 0.20 [0.07, 0.33] units at the 97(th percentile. CONCLUSIONS: We confirmed that risk factors for childhood overweight are associated with greater shifts in the upper parts of the children's BMI distribution than in the middle and lower parts. These findings pertain also to teenagers and might possibly help to explain the secular shift in the upper BMI percentiles in children and adolescents.

    Objectives: We aimed to establish normal ultrasonographic (US) values of internal jugular vein (IJV) sizes in children/adolescents aged birth to 18 years and to determine the correlation of US measurements with age, height, weight and body surface area (BSA) of children in different age groups. Methods: Two hundred and thirty-six healthy children (0–18 years) were divided into four groups according to their age (0–2, 3–6, 7–12, and 13–18 years). US measurements (transverse, anteroposterior diameter, and cross-sectional area at rest and during the Valsalva maneuver) of bilateral IJVs were taken at the level of cricoid cartilage. Results: Our study gives information about the reference values in children between birth to 18 years of age. There were significant differences between measurements taken at rest and during the Valsalva maneuver in all age groups. Moderate to strong correlations (clinically significant) between age, height and BSA of the subjects and IJV measurements were detected only in the 0–2 years age group. The strength of the correlations decreased with increasing age. Pearson's correlation revealed that height had the strongest and weight had the weakest correlation with US measurements. ‘Height’ was an independent variable on the right, and ‘age’ on the left side, except for rest CSA, when a regression analysis was performed for clinically significant correlations. Conclusions: Determination of normal reference values for US measurements of the IJV and knowledge of correlation with age, height, weight and BSA might be valuable during interventional procedures and for the diagnosis of phlebectasia in children/adolescents.

    Delayed sleep phase disorder is characterized by a delay in the timing of the major sleep period relative to conventional norms. The sleep period itself has traditionally been described as normal. Nevertheless, it is possible that sleep regulatory mechanism disturbances associated with the disorder may affect sleep duration and/or architecture. Polysomnographic data that may shed light on the issue are scarce. Hence, the aim of this study was to examine polysomnographic measures of sleep in adolescents and young adults with delayed sleep phase disorder, and to compare findings to that of healthy controls. A second aim was to estimate dim light melatonin onset as a marker of circadian rhythm and to investigate the phase angle relationship (time interval) between dim light melatonin onset and the sleep period. Data from 54 adolescents and young adults were analysed, 35 diagnosed with delayed sleep phase disorder and 19 healthy controls. Results show delayed timing of sleep in participants with delayed sleep phase disorder, but once sleep was initiated no group differences in sleep parameters were observed. Dim light melatonin onset was delayed in participants with delayed sleep phase disorder, but no difference in phase angle was observed between the groups. In conclusion, both sleep and dim light melatonin onset were delayed in participants with delayed sleep phase disorder. The sleep period appeared to occur at the same circadian phase in both groups, and once sleep was initiated no differences in sleep parameters were observed.

    Full Text Available Abstract Background The axial complex of echinoderms (Echinodermata is composed of various primary and secondary body cavities that interact with each other. In sea urchins (Echinoidea, structural differences of the axial complex in "regular" and irregular species have been observed, but the reasons underlying these differences are not fully understood. In addition, a better knowledge of axial complex diversity could not only be useful for phylogenetic inferences, but improve also an understanding of the function of this enigmatic structure. Results We therefore analyzed numerous species of almost all sea urchin orders by magnetic resonance imaging, dissection, histology, and transmission electron microscopy and compared the results with findings from published studies spanning almost two centuries. These combined analyses demonstrate that the axial complex is present in all sea urchin orders and has remained structurally conserved for a long time, at least in the "regular" species. Within the Irregularia, a considerable morphological variation of the axial complex can be observed with gradual changes in topography, size, and internal architecture. These modifications are related to the growing size of the gastric caecum as well as to the rearrangement of the morphology of the digestive tract as a whole. Conclusion The structurally most divergent axial complex can be observed in the highly derived Atelostomata in which the reorganization of the digestive tract is most pronounced. Our findings demonstrate a structural interdependence of various internal organs, including digestive tract, mesenteries, and the axial complex.

    The upcoming Juno and Cassini gravity measurements of Jupiter and Saturn, respectively, will allow probing the internal dynamics of these planets through accurate analysis of their gravity spectra. To date, two general approaches have been suggested for relating the flow velocities and gravity fields. In the first, barotropic potential surface models, which naturally take into account the oblateness of the planet, are used to calculate the gravity field. However, barotropicity restricts the flows to be constant along cylinders parallel to the rotation axis. The second approach, calculated in the reference frame of the rotating planet, assumes that due to the large scale and rapid rotation of these planets, the winds are to leading order in geostrophic balance. Therefore, thermal wind balance relates the wind shear to the density gradients. While this approach can take into account any internal flow structure, it is limited to only calculating the dynamical gravity contributions, and has traditionally assumed spherical symmetry. This study comes to relate the two approaches both from a theoretical perspective, showing that they are analytically identical in the barotropic limit, and numerically, through systematically comparing the different model solutions for the gravity harmonics. For the barotropic potential surface models we employ two independent solution methods - the potential-theory and Maclaurin spheroid methods. We find that despite the sphericity assumption, in the barotropic limit the thermal wind solutions match well the barotropic oblate potential-surface solutions.

    Many regions of the world feel the pressure to interconnect electric power systems internationally. Regional integrations of the electricity sector have become part of free trade and common market initiatives, though the steps individual national jurisdictions take towards developing integrated systems vary. In this article, we review three regions concerned with common market initiatives and at different stages of integration processes that involve infrastructural, regulatory, and commercial decisions. First, we examine the North European countries in the Nordic Council, then countries in the Southern Cone of South America in MERCOSUR, and finally Mexico, the United States and Canada, linked under NAFTA. This comparative study highlights the potential, but also the many hurdles, that electricity sector integrations face. The study suggests a framework for measuring the level of electricity sector integration that could be applied to other regions.

    Supervised field trials were carried out in a commercial orchard in 2011. The purpose of the study was to assess the usefulness of the comparative method to examine the mechanism of disappearance of pesticide residues. Captan and trifloxystrobin residues were determined with the use of gas chromatograph equipped with a micro-electron capture detector. Disappearance trends of captan and trifloxystrobin residues in fruit and leaves were estimated using the method of internal normalisation, and based on that, the courses of concentration changes of these substances on fruit and leaves and the amount of these substances in one apple were established. The initial deposits of trifloxystrobin on leaves and fruits dropped by 50% within 8 and 4 days after treatment, respectively, in both varieties, whereas captan residues dropped by 50% within 29 days in leaves and 7 days in apples of the Olive Yellow varieties.

    The choice of general (GA) versus local anesthesia (LA) in open inguinal hernia repair (OIHR) has a substantial financial impact and may influence clinical outcomes. Our study compares postoperative quality of life (QOL) in patients undergoing OIHR under LA versus GA. A cooperative prospective study from centers in 10 countries was performed through the International Hernia Mesh Registry from 2007 to 2012. QOL was compared at one, six, 12, and 24 months for LA versus GA with univariate and multivariate analysis controlling for known confounding variables. Of 1128 patients who underwent OIHR, 585(52%) used GA and 533(48%) used LA. Most were male (92%) with unilateral (94%), primary (91%) repairs with a mean age 57 ± 16 years. There was no difference (P > 0.05) in age, gender, operative time, mesh size, length of stay, infection, recurrence, reoperation, or death. Multivariate analysis demonstrated significant QOL differences between groups: GA had higher odds of discomfort at one and six months [odds ratio (OR) 3.3, 2.0], movement limitation at one and six months (OR 3.5, 2.8), and mesh sensation at one and 12 months (OR 2.9, 1.8). Overall, patients undergoing OIHR under LA had improved postoperative QOL in the short and long term compared with GA.

    Full Text Available Sleeping sickness (human African trypanosomiasis [HAT] is a neglected tropical disease with limited treatment options that currently require parenteral administration. In previous studies, orally administered pafuramidine was well tolerated in healthy patients (for up to 21 days and stage 1 HAT patients (for up to 10 days, and demonstrated efficacy comparable to pentamidine.This was a Phase 3, multi-center, randomized, open-label, parallel-group, active control study where 273 male and female patients with first stage Trypanosoma brucei gambiense HAT were treated at six sites: one trypanosomiasis reference center in Angola, one hospital in South Sudan, and four hospitals in the Democratic Republic of the Congo between August 2005 and September 2009 to support the registration of pafuramidine for treatment of first stage HAT in collaboration with the United States Food and Drug Administration. Patients were treated with either 100 mg of pafuramidine orally twice a day for 10 days or 4 mg/kg pentamidine intramuscularly once daily for 7 days to assess the efficacy and safety of pafuramidine versus pentamidine. Pregnant and lactating women as well as adolescents were included. The primary efficacy endpoint was the combined rate of clinical and parasitological cure at 12 months. The primary safety outcome was the frequency and severity of adverse events. The study was registered on the International Clinical Trials Registry Platform at www.clinicaltrials.gov with the number ISRCTN85534673.The overall cure rate at 12 months was 89% in the pafuramidine group and 95% in the pentamidine group; pafuramidine was non-inferior to pentamidine as the upper bound of the 95% confidence interval did not exceed 15%. The safety profile of pafuramidine was superior to pentamidine; however, 3 patients in the pafuramidine group had glomerulonephritis or nephropathy approximately 8 weeks post-treatment. Two of these events were judged as possibly related to

    Background Our aim was to identify genetic variants associated with blood pressure (BP) in childhood and adolescence. Methods and Results Genome-wide association study data from participating European ancestry cohorts of the Early Genetics and Lifecourse Epidemiology (EAGLE) Consortium was meta-analyzed across 3 epochs; prepuberty (4–7 years), puberty (8–12 years), and postpuberty (13–20 years). Two novel loci were identified as having genome-wide associations with systolic BP across specific age epochs: rs1563894 (ITGA11, located in active H3K27Ac mark and transcription factor chromatin immunoprecipitation and 5′-C-phosphate-G-3′ methylation site) during prepuberty (P=2.86×10–8) and rs872256 during puberty (P=8.67×10–9). Several single-nucleotide polymorphism clusters were also associated with childhood BP at P<5×10–3. Using a P value threshold of <5×10–3, we found some overlap in variants across the different age epochs within our study and between several single-nucleotide polymorphisms in any of the 3 epochs and adult BP-related single-nucleotide polymorphisms. Conclusions Our results suggest that genetic determinants of BP act from childhood, develop over the lifecourse, and show some evidence of age-specific effects. PMID:26969751

    Full Text Available Background: Obesity is prevalent among adolescents and is associated with serious health consequences. Roux-en-Y Gastric Bypass (RYGB and Sleeve Gastrectomy (SG are bariatric procedures that cause significant weight loss in adults and are increasingly being performed in adolescents with morbid obesity. Data comparing outcomes of RYGB versus SG in this age-group are scarce. This study aims to compare short-term (1-6 months and longer-term (7-18 months body mass index (BMI and biochemical outcomes following RYGB and SG in adolescents/young adults.Methods: A retrospective study using data extracted from medical records of patients 16-21 years who underwent RYGB or SG between 2012-2014 at a tertiary care academic medical center. Results: Forty-six patients were included in this study: 24 underwent RYGB and 22 underwent SG. Groups did not differ for baseline age, sex, race or BMI. BMI reductions were significant at 1-6 months and 7-18 months within groups (p<0.0001, but did not differ by surgery type (p= 0.65 and 0.09, for 1-6 months and 7-18 months, respectively. Over 7-18 months, within-group improvement in low density lipoprotein (LDL (-24±6 in RYGB, p=0.003, vs. -7±9mg/dL in SG, p=0.50 and non-high density lipoprotein (non-HDL cholesterol (-23±8 in RYGB, p=0.02, vs. -12±7 in SG, p=0.18 appeared to be of greater magnitude following RYGB. However, differences between groups did not reach statistical significance. When divided by non-alcoholic steatohepatitis stages (NASH, patients with Stage II-III NASH had greater reductions in ALT levels vs. those with Stage 0-I NASH (-45±18 vs -9±3, p=0.01 after 7-18 months. RYGB and SG groups did not differ for the magnitude of post-surgical changes in liver enzymes. Conclusion: RYGB and SG did not differ for the magnitude of BMI reduction across groups, though changes trended higher following RYGB. Further prospective studies are needed to confirm these findings.

    Despite major improvements in outcome over the past decades, acute myeloid leukemia (AML) remains a life-threatening malignancy in children, with current survival rates of ∼70%. State-of-the-art recommendations in adult AML have recently been published in this journal by Döhner et al. The primary goal of an international expert panel of the International BFM Study Group AML Committee was to set standards for the management, diagnosis, response assessment, and treatment in childhood AML. This paper aims to discuss differences between childhood and adult AML, and to highlight recommendations that are specific to children. The particular relevance of new diagnostic and prognostic molecular markers in pediatric AML is presented. The general management of pediatric AML, the management of specific pediatric AML cohorts (such as infants) or subtypes of the disease occurring in children (such as Down syndrome related AML), as well as new therapeutic approaches, and the role of supportive care are discussed.

    Huntington disease (HD) belongs to the group of neurodegenerative disorders characterized by unstable expanded trinucleotide repeats. In the case of HD, the expansion of a CAG repeat occurs in the IT15 gene. The detection of the expanded CAG repeats has usually involved the electrophoretic separation of polymerase chain reaction (PCR) amplification products using conventional agarose and acrylamide gel electrophoresis. We have undertaken the comparative analysis of sizing CAG repeats of the IT15 gene using radioactive and fluorescent PCR amplification, and the subsequent separation of these products by slab gel and capillary electrophoresis. The assays have been performed on both cloned and sequenced CAG repeats, as well as genomic DNA from HD patients with a wide range of repeat lengths. The mobility of the CAG repeat amplification products of the IT15 gene is greater using capillary electrophoresis compared to slab gel electrophoresis. The analysis of 40 DNA samples from HD patients indicates that the mobility difference increases with the length of the repeat. However, we have devised an allele ladder for sizing the CAG repeats. This ladder provides a mandatory internal calibration system for diagnostic purposes and enables the confident use of either capillary or slab gel electrophoresis for sizing HD alleles.

    Single-nucleotide polymorphisms (SNPs) determined based on SNP arrays from the international HapMap consortium (HapMap) and the genetic variants detected in the 1000 genomes project (1KGP) can serve as two references for genomewide association studies (GWAS). We conducted comparative analyses to provide a means for assessing concerns regarding SNP array-based GWAS findings as well as for realistically bounding expectations for next generation sequencing (NGS)-based GWAS. We calculated and compared base composition, transitions to transversions ratio, minor allele frequency and heterozygous rate for SNPs from HapMap and 1KGP for the 622 common individuals. We analysed the genotype discordance between HapMap and 1KGP to assess consistency in the SNPs from the two references. In 1KGP, 90.58% of 36,817,799 SNPs detected were not measured in HapMap. More SNPs with minor allele frequencies less than 0.01 were found in 1KGP than HapMap. The two references have low disc ordance (generally smaller than 0.02) in genotypes of common SNPs, with most discordance from heterozygous SNPs. Our study demonstrated that SNP array-based GWAS findings were reliable and useful, although only a small portion of genetic variances were explained. NGS can detect not only common but also rare variants, supporting the expectation that NGS-based GWAS will be able to incorporate a much larger portion of genetic variance than SNP arrays-based GWAS.

The International Headache Society recently added revised criteria (ICHD-IIR for chronic migraine to its Appendix. We retrospectively reviewed all charts of 34 children and adolescents (<17 years with primary CDH presenting to the outpatient clinic of the Universitary Department of Neuropediatrics of Lille between February 2004 and February 2006 and tried to classify their CDH according to both S-L criteria and the recently published ICHD-IIR. Thirty-two children (94% and 33 children (97% could respectively be successfully classified into one subtype of CDH according to the S-L classification and the ICHD-IIR. Transformed migraine was the most common diagnosis (61.8%, followed by new daily-persistent headache (20.6% when the S-L criteria were used. Twenty-three children and adolescents (67.6% could be classified under one of the migraine categories according to the ICHD-IIR classification. We think that both S-L and ICHD-II classifications, when used with detailed headache histories and diaries, are adequate to classify chronic daily headache in children and adolescents.Keywords: chronic daily headache, classification, children, adolescents

    ça nos escores de Apgar no primeiro minuto.PURPOSE: to describe the obstetric outcomes in pregnant adolescents at a tertiary hospital and to compare the maternal and labor outcomes between precocious and late adolescents. METHODS: in a transversal analytical study, 2058 cases were evaluated, considering 322 (15.65% from the precocious group and 1736 (84.35% from the late group that delivered at the "Maternidade Escola Assis Chateaubriand/UFC" from January 1, 2000 to December 31, 2000. The clinical complications in the prenatal period, kind of delivery, indications for cesarean section, birth gestational age at birth, birth weight, comparison of birth weight and gestational age, Apgar score at the first and fifth minute, presence of malformations, and neonatal death were analyzed. The exact Fisher and the chi2 tests were used to compare both groups. The prevalence ratio was calculated. RESULTS: from of total of deliveries, 25.95% belonged to adolescents. The average age was 17.19 years. Prenatal visits were made by 88% of the patients, but 60% had an insufficient number of visits. The most frequent clinical situations were preeclampsia (14.72%, anemia (12.97% and urinary tract infections (6.37%, with no statistical difference between the groups. Thirty-one and three percent of the births were by cesarean section, preeclampsia being the main indication in the two age groups (25 and 23%, respectively. The frequency of an Apgar score less than 7 at the first minute was 19,9% in the precocious adolescent group and 14,2% in the late adolescent group (x²=6,96, p=0.008. There was no statistical difference regarding prematurity rate (20.2 vs 16.1%, low-birth weight infants (12.4 vs 10.4%, low Apgar score at the fifth minute (5.3 vs 3.3%, congenital malformations (3.1 vs 2.7%, and neonatal death (5.3 vs 3.3%. CONCLUSIONS: the precocious and late pregnant adolescents presented similar pregnancy evolution and obstetric outcomes, except for the differences of the first minute Apgar

    Full Text Available Background Headaches and sleep disorders may influence academic performances, personality, memory, and interpersonal relationships. Migraine is the most common headache type seen in adolescents. Although headaches and sleep disorders are believed to be related, there has been little study in this area. Objectives To assess the relationship between migraine and sleep disorders in adolescents and compare different types of sleep disorders found in adolescents with migraine vs. healthy adolescents. Methods We conducted a cross sectional study in December 2009 on students of three junior high schools in the Secanggang District, Langkat Rregency, North Sumatera. We included adolescents aged 12 to 17 years who suffered from migraines, as defined by the International Classification of Headache Disorders, 2nd edition criteria (ICHD-II, and healthy adolescents who did not experience migraines as the control group. Parents filled questionnaires on their child’s sleep patterns for one week. Results A total of 100 adolescents were enrolled in the study, consisted of 50 adolescents in the migraine group and the others 50 in the control group. There was a significant difference in the incidence of sleep disorders between the two groups (76% and 30%, in the case and control groups, respectively; P=0.0001. Moreover, significant differences were also found in the prevalence of different sleeping disorder types between the case and control groups, i.e. insomnia (62% and 30%, respectively; P=0.003, sleep apnea (56% and 16%, respectively; P=0.0001, restlessness (56% and 18%, respectively; P=0.0001, parasomnia (76% and 10%, respectively; P=0.0001, narcolepsy (42% and 16%, respectively; P=0.008, and excessive daytime sleepiness (50% and 26%, respectively; P= 0.023. Conclusions Migraine in adolescents is significantly associated with sleep disorders. Parasomnia is the most common type of sleeping disorder observed in adolescents with migraines in our study

    Cyclin D1 amplification and/or overexpression contribute to the loss of the regulatory circuits that govern G1-S transition phase of the cell cycle, playing pivotal roles in different human malignant tumors, including breast, colon, prostate cancer, lymphoma, melanoma and neuroblastoma. In vitro studies have shown that cyclin D1 is overexpressed in Ewing's sarcoma (EWS)/peripheral Primitive Neuroectodermal Tumor (pPNET), but not in rhabdomyosarcoma cell lines. Only a few immunohistochemical studies are available on cyclin D1 expression in EWS/pPNET, which confirmed its expression only in a limited number of cases. The aim of the present study was a comparative immunohistochemical analysis of the expression and distribution of cyclin D1 in a large series of pediatric/adolescent soft tissue EWS/pPNETs and rhabdomyosarcomas (both embryonal and alveolar subtypes) to assess its potential usefulness in their differential diagnosis. Notably cyclin D1 was strongly and diffusely expressed in all cases (20/20) of EWS/pPNET, while it was lacked in all cases (15/15) of rhabdomyosarcomas. Immunohistochemical overexpression of cyclin D1 in EWS/pPNET is a novel finding which could be exploitable as a diagnostic immunomarker for this tumor. Although highly sensitive, cyclin D1 is not specific for EWS/pPNET, and thus it should not be evaluated alone but in the context of a wide immunohistochemical panel. Accordingly, we first emphasize that when pathologists are dealing with a small round blue cell tumor of soft tissues in pediatric/adolescent patients, a strong and diffuse nuclear expression of cyclin D1 is of complementary diagnostic value to CD99 and FLI-1 in confirming diagnosis of EWS/pPNET and in ruling out rhabdomyosarcoma.

    2013-01-01

    Full Text Available Based on an internal tidal model, the practical performances of the limited-memory BFGS (L-BFGS method and two gradient descent (GD methods (the normal one with Wolfe’s line search and the simplified one are investigated computationally through a series of ideal experiments in which the open boundary conditions (OBCs are inverted by assimilating the interior observations with the adjoint method. In the case that the observations closer to the unknown boundary are included for assimilation, the L-BFGS method performs the best. As compared with the simplified GD method, the normal one really uses less iteration to reach a satisfactory solution, but its advantage over the simplified one is much smaller than expected. In the case that only the observations that are further from the unknown boundary are assimilated, the simplified GD method performs the best instead, whereas the performances of the other two methods are not satisfactory. The advanced L-BFGS algorithm and Wolfe’s line search still need to be improved when applied to the practical cases. The simplified GD method, which is controllable and easy to implement, should be regarded seriously as a choice, especially when the classical advanced optimization techniques fail or perform poorly.

The Manchester Ice Nucleus Chamber (MINC is a concentric-cylinder continuous flow diffusion chamber (CFDC. A full explanation of the MINC instrument is given here, along with first results and a comparison to an established instrument of similar design (Colorado State University CFDC during sampling of common ice nucleating aerosols at the 2007 International workshop on Comparing Ice nucleation Measuring Systems (ICIS-2007. MINC and CSU-CFDC detected the onset of ice nucleation under similar conditions of temperature and supersaturation for several different types of ice nuclei. Comparisons of the ratio of ice nuclei to total aerosol concentrations as a function of supersaturation with respect to water (SSw showed agreement within one order of magnitude. Possible reasons for differences between the two instruments relating to differences in their design are discussed, along with suggestions to future improvements to the current design.

    The extent of agreement between International Labour Office (ILO) and clinical readings of chest x ray films from construction workers was studied. From a survey of 5898 workers 258 subjects with a profusion of small opacities of > or = 1/1 and a stratified sample of subjects with profusion ILO profusion category > or = 1/1 were clinically recorded as non-normal for the parenchyma. The proportion of films recorded as pneumoconiotic (or possibly so) was especially low for irregular opacities (22%), but increased with the profusion category (both rounded and irregular) as well as with the size of rounded opacities (p 3/11, q 12/25, r 3/4). Only with the profusion category > or = 2/1 were most of the films recorded as pneumoconiotic. The specificity and sensitivity were highest in the geographical areas where a few clinical readers had assessed many films each. The proportion of false negative clinical reports was low for circumscribed pleural thickening of the chest wall (9%) and diaphragmatic pleural thickening (6%). For calcified pleural changes and for the combination of diffuse pleural thickening and obliteration of the costophrenic angle, false negative reports were absent. The present study shows an unsatisfactory sensitivity for clinical compared with ILO readings as a means for screening the parenchyma of workers with a risk of pneumoconiosis.

    The oil industry is one of the more global sectors of the economy, with its economic agents acting and competing at the same time in many countries. The limitation of available funds for investment and competition in global scale make the host countries adapt some elements of their concession instruments, as a way to attract greater investments. The comparison of legal framework of diverse host countries is an essential part in this process of decision and an indispensable tool to help the host countries in the dispute for the attraction of international investors. Therefore, to place Brazil in this process of global competition between States is necessary the knowledge and the comparison between the conditions offered for its legal system and offered for countries considered as models of attraction of investment. This work intends to offer a comparative study of relevant legal aspects for the oil industry, amongst them: characterization of the concession instrument; reach of the participation of the state-owned company; intervention of the State in the private management. The comparison will be made between countries with different characteristics, to obtain a consolidation of paradigms that helps the evolution of the Brazilian exploration and production legal framework.

    Full Text Available This article presents a review of some of the research in the international context aimed at unveiling and valuing the experience of young people in experiences and beliefs regarding citizenship (Burke, 2007. Such research is generally intended to obtain information on students’ knowledge, attitudes and civic behavior in their own schools. We will highlight throughout the present paper that previous studies and the current state of scientific knowledge in civic education focuses on purely formal and structural aspects and lack a deep understanding and interpretation of the experiences of young citizens. We conclude, after our review, that it is necessary to include more comprehensive factors in the research and enquiry into the experiences and civic training of the youth.

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

    Full Text Available Coilia nasus is widely distributed in the Yangtze River, the coastal waters of China, Korea and the Ariake Sound of Japan. Several ecotypes exist and this provides a useful model for the study of comparative diversity between molecular markers. Here we analyze and compare the nucleotide sequences between single-copy ribosomal protein S7 gene intron 1 (rpS7 and multiple-copy ribosomal internal transcribed spacer 1 (ITS1 in this species to compare the phylogenetic signal of the two nuclear genes. Nucleotide substitutions among the two gene sequences and partial sequence of mitochondrial cytochrome c oxidase subunit I (COI gene were also analyzed. A total of 115 clones for rpS7 and 122 clones for ITS1 were obtained from 37 specimens. The nucleotide sequence length is 741 to 743 bp for rpS7 and 334 to 348 bp for ITS1. Intra- and inter-specimen variation in rpS7 results from nucleotide substitution, while such variation in ITS1 is mainly due to different numbers of short base repeats. The content of G + C is lower in rpS7 (43.5% than in ITS1 (68.2%. Our results indicate that the proportion of the sequence variable sites is higher in rpS7 (61 than in ITS1 (23; the informative parsimony of rpS7 is evidently higher than that of ITS1 (26 vs. 2; the overall ratio between transitions and transversions in ITS1 is slightly lower than in rpS7, but remarkably lower than in COI. These results suggest that rpS7 is more suitable than ITS1 as a marker for genetic divergence of this group. Furthermore, gene flow is observed between the different geographic populations of C. nasus from the phylogeny of this species based on rpS7, showing that rpS7 has more evolutionary characteristics for understanding the processes of genomic evolution at the intraspecific level.

    Purpose: The first aim was to compare medial patellofemoral ligament injury patterns in children and adolescents after first-time lateral patellar dislocations with the injury patterns in adults. The second aim was to evaluate the trochlear groove anatomy at different developmental stages of the growing knee joint. Materials and methods: Knee magnetic resonance (MR) images were collected from 22 patients after first-time patellar dislocations. The patients were aged 14.2 years (a range of 11-15 years). The injury pattern of the medial patellofemoral ligament was analysed, and trochlear dysplasia was evaluated with regard to sulcus angle, trochlear depth and trochlear asymmetry. The control data consisted of MR images from 21 adult patients who were treated for first-time lateral patellar dislocation. Results: After patellar dislocation, injury to the medial patellofemoral ligament was found in 90.2% of the children and in 100% of the adult patients. Injury patterns of the medial patellofemoral ligament were similar between the study group and the control group with regard to injury at the patellar attachment site (Type I), to the midsubstance (Type II) and to injury at the femoral origin (Type III) (all p > 0.05). Combined lesions (Type IV) were significantly less frequently observed in adults when compared to the study group (p = 0.02). The magnitude of trochlear dysplasia was similar in children, adolescents and adults with regard to all three of the measured parameter-values (all p > 0.05). In addition, the articular cartilage had a significant effect on the distal femur geometry in both paediatrics and adults. Conclusion: First, the data from our study indicated that the paediatric medial patellofemoral ligament injury patterns, as seen on MR images, were similar to those in adults. Second, the trochlear groove anatomy and the magnitude of trochlear dysplasia, respectively, did not differ between adults and paediatrics with patellar instability. Thus

    碳税作为一种控制二氧化碳排放的经济手段受到许多学者的青睐,国外一些学者主张通过在国际层面实行碳税来实现全球二氧化碳减排的目标,并提出了不同的设计构想.但至今仍没有研究者对国际上的国际碳税提议进行系统的归纳.对已有国际碳税提议进行归纳和分析即成为本文的目的.本文将已有典型的国际碳税提议归纳成四种方案,即统一的国际税方案、有差异的国际税方案、统一的国内税方案和国内税+边境调节税方案,分别阐述了每种方案的内容和特征,并运用比较分析的方法从成本效益、公平性、参与广泛性及可操作性四个方面对所归纳的四种方案进行对比分析.通过分析得出,如果仅基于成本效益、公平性、参与广泛性及可操作性四个指标,前三种方案差别不大,但都明显优于第四种方案,因此第四种方案是最劣的.但如果考虑到方案实行的现实条件和推动力,最劣的第四种方案是短期内最可能实现的,并且,最优的国际碳税方案可能需由最劣的方案逐次演化而成,而难以直接实现.%As one of the economic policies to control carbon dioxide (CO2) emissions, carbon tax is favored by many scholars. Some foreign scholars advocate that carbon tax should be implemented worldwide to reach the goal of global carbon emission abatement and put forth a few different proposals. However, so far, there is no study focusing on the summary and induction of these proposals. In this article the existing proposals are summarized and analyzed. The Typical proposals are sorted into four international carbon tax options, which are Uniform International Taxes, Non-uniform International Taxes, Harmonized Domestic Taxes and Domestic Taxes and Border-Tax Adjustment, and their main contents and features are described respectively, followed by comparisons of these options in the perspectives of cost-effectiveness, equity

    Full Text Available Starting from the stipulations of the two well-known internal control system models – COSO and CoCo - the purpose of this paper is to focus on the Romanian framework for credit institutions – trying to to identify on which international model is our national one most appropriate to. The research methodology is based on an empirical analysis between Romanian regulation and the models already mentioned. To reach to a conclusion we tried to identify several key issues closely related to information and communication, and to determine the degree of similarities and dissimilarities between the three selected frameworks, by using statistical indicators. The paper has some limitations, too, because it only approaches formal harmonization. So, those issues analyzed through the regulations’ perspectives need to be closely quantified in matters of their actual implementation, which offer us outlooks of future research.

    Full Text Available Background & aim: At the present time, obesity as one of the most important public health problems which has widely prevailed throughout the world. The aim of this study was to compare the effectiveness of the attachment-based therapy, dietary-therapy, and the combined treatment method on weight (body mass index loss in obese high school adolescents of Yasuj city. Methods: This clinical trial study was conducted on sixty female high school students of Yasuj, Iran, diagnosed with overweight and obesity. Subjects were randomly selected and divided into four equal groups, and their body mass indexes were assessed. Three intervention groups were exposed to the attachment-based therapy, dietary-therapy, and combined treatment method. The fourth group (control did not receive any intervention. Following the treatment period, body mass indexes of the four groups were assessed. The data were analyzed by implementing Univariate analysis of covariance and LSD post hoc tests. Results: All three intervention methods of weight loss significantly increased compared with the control group (p < 0.001. However, the combination therapy was more effective. Conclusions: According to the findings of this study, it was concluded that although interventional techniques such as attachment-based therapy and dietary therapy are effective for weight loss, the combination of these two methods were more effective for weight loss.

    Full Text Available Measurement of RNA can be used to study and monitor a range of infectious and non-communicable diseases, with profiling of multiple gene expression mRNA transcripts being increasingly applied to cancer stratification and prognosis. An international comparison study (Consultative Committee for Amount of Substance (CCQM-P103.1 was performed in order to evaluate the comparability of measurements of RNA copy number ratio for multiple gene targets between two samples. Six exogenous synthetic targets comprising of External RNA Control Consortium (ERCC standards were measured alongside transcripts for three endogenous gene targets present in the background of human cell line RNA. The study was carried out under the auspices of the Nucleic Acids (formerly Bioanalysis Working Group of the CCQM. It was coordinated by LGC (United Kingdom with the support of National Institute of Standards and Technology (USA and results were submitted from thirteen National Metrology Institutes and Designated Institutes. The majority of laboratories performed RNA measurements using RT-qPCR, with datasets also being submitted by two laboratories based on reverse transcription digital polymerase chain reaction and one laboratory using a next-generation sequencing method. In RT-qPCR analysis, the RNA copy number ratios between the two samples were quantified using either a standard curve or a relative quantification approach. In general, good agreement was observed between the reported results of ERCC RNA copy number ratio measurements. Measurements of the RNA copy number ratios for endogenous genes between the two samples were also consistent between the majority of laboratories. Some differences in the reported values and confidence intervals (‘measurement uncertainties’ were noted which may be attributable to choice of measurement method or quantification approach. This highlights the need for standardised practices for the calculation of fold change ratios and

    Full Text Available Abstract Background The effectiveness of bracing on preventing curve progression in coronal plane for mild and moderate adolescent idiopathic scoliosis (AIS patients has been confirmed by previous radiographic researches. However, a hypokyphotic effect on the sagittal plane has been reported by a few studies. A relatively increasing number of AIS patients were noticed to wear a new kind of elastic orthotic belt for the treatments of scoliosis without doctors' instructions. We postulate the correcting mechanism of this new appliance may cause flattening of the spine. To our knowledge, no study has investigated the effects of this new orthosis on the sagittal profile of AIS patients. The aim of this study was to evaluate and compare the effects of elastic orthotic belt and Milwaukee brace on the sagittal alignment in AIS patients. Methods Twenty-eight female AIS patients with mild or moderate thoracic curves were included in this study. Standing full-length lateral radiographs were obtained in three conditions: natural standing posture without any treatment, with elastic orthotic belt and with Milwaukee brace. Thoracic kyphosis (TK, lumber lordosis (LL and pelvic incidence (PI were measured and compared between the above three conditions. Results Both elastic orthotic belt and Milwaukee brace can lead to significant decrease of TK, however, the decrease of TK after wearing elastic orthotic belt is significantly larger than that after wearing Milwaukee brace. Compared with no treatment, LL was found to be significantly smaller after wearing Milwaukee brace, however, such significant decrease was not noted after wearing elastic orthotic belt. No significant changes were observed for the PI between 3 conditions. Conclusions The elastic orthotic belt could lead to more severe thoracic hypokyphosis when compared with Milwaukee brace. This belt may not be a suitable conservative method for the treatment of mild and moderate AIS patients.

    Antimicrobial susceptibility testing for Helicobacter pylori is increasingly important due to resistance to the most used antimicrobials agents. Only agar dilution method is approved by CLSI, but it is difficult to perform routinely. We evaluated the reliability of E-test and disk diffusion comparing to agar dilution method on Helicobacter pylori antimicrobial susceptibility testing. Susceptibility testing was performed for amoxicillin, clarithromycin, furazolidone, metronidazole and tetracycline using E-test, disk-diffusion and agar dilution method in 77 consecutive Helicobacter pylori strains from dyspeptic children and adolescents. Resistance rates were: amoxicillin - 10.4%, 9% and 68.8%; clarithromycin - 19.5%, 20.8%, 36.3%; metronidazole - 40.2%33.7%, 38.9%, respectively by agar dilution, E-test and disk diffusion method. Furazolidone and tetracycline showed no resistance rates. Metronidazole presented strong correlation to E-test (r = 0.7992, p Helicobacter pylori susceptibility testing. Disk diffusion method presented high disagreement and high rates of major errors.

  18. The clinical effectiveness of a brief consultation and advisory approach compared to treatment as usual in child and adolescent mental health services.

    A brief consultation and advice (BCA) approach to dealing with routine referrals was introduced into a child and adolescent mental health service (CAMHS) over an 18-month period. This is a time-limited, client-centred and solution-focused approach to dealing with common non-complex referrals. The model proposes that all families are seen for an initial \\'consultation\\' appointment followed by a maximum of two further appointments. A randomized controlled study compared the clinical effectiveness of BCA treatment with treatment as usual (TAU) over a 6-month period. The parents of children referred to CAMHS were eligible to participate if their child was deemed \\'non-complex\\'. Ethical approval was granted by the relevant ethics committee. Families who consented to participate in the study were randomly allocated to either the BCA or TAU group. Sixty children enrolled in the study. Both groups showed improvements on a number of variables at 3 months post treatment, but only those receiving BCA showed continued improvement at 6 months. Participants in both groups showed high levels of satisfaction with the treatment received. Participants in the TAU group expressed dissatisfaction with long waiting times and had a higher drop out rate than the BCA treatment group. During the time frame studied, the introduction of the BCA approach did not lead to a decrease in overall mean waiting time. These results and the usefulness of a BCA model are discussed.

    The prosthetic foot plays an important role in propelling, breaking, balancing and supporting body loads while the amputee ambulates on different grounds. It is therefore important to quantify the effect of the prosthetic foot mechanism on biomechanical parameters, in order to prevent pressure ulcers and deep tissue injury. Our aim was to monitor the internal stresses in the residuum of transtibial amputation (TTA) prosthetic-users ambulating on different terrains, which the amputees encounter during their daily activities, i.e. paved floor, grass, ascending and descending stairs and slope. We specifically aimed to compare between the internal stresses in the TTA residuum of amputees ambulating with a novel hydraulic prosthetic foot compared to conventional energy storage and return (ESR) prosthetic feet. Monitoring of internal stresses was accomplished using a portable subject-specific real-time internal stress monitor. We found significant decrease (phydraulic foot, compared to walking with ESR feet. The loading rate calculated while ambulating with the hydraulic foot was at least three times lower than the loading rate calculated while ambulating with the ESR foot. Although the average decrease in internal stresses was ≈ 2-fold larger when replacing single-toe ESR feet with the hydraulic foot than when replacing split-toed ESR feet with the hydraulic foot, the differences were statistically insignificant. Our findings suggest that using a hydraulic prosthetic foot may protect the distal tibial end of the TTA residuum from high stresses, therefore preventing pressure-related injury and pain.

    Sialoadhesin (Sn) is a surface receptor expressed on resident macrophages with the ability to bind with sialic acids. During inflammation, an upregulation of Sn is observed. Upon binding of monoclonal antibodies to Sn, the receptor becomes internalized and this has been observed in multiple species. The latter characteristic, combined with the strong upregulation of Sn on inflammatory macrophages and the fact that Sn-positive macrophages contribute to certain inflammatory diseases, makes Sn an interesting entry portal for phenotype-modulating or cytotoxic drugs. Such drugs or toxins can be linked to Sn-specific antibodies which should enable their targeted uptake by macrophages. However, the activity of such drugs depends not only on their internalization but also on the intracellular trafficking and final fate in the endolysosomal system. Although information is available for porcine Sn, the detailed mechanisms of human and mouse Sn internalization and subsequent intracellular trafficking are currently unknown. To allow development of Sn-targeted therapies, differences across species and cellular background need to be characterized in more detail. In the current report, we show that internalization of human and mouse Sn is dynamin-dependent and clathrin-mediated, both in primary macrophages and CHO cell lines expressing a recombinant Sn. In primary macrophages, internalized Sn-specific F(ab')2 fragments are located mostly in the early endosomes. With Fc containing Sn-specific antibodies, there is a slight shift towards lysosomal localization in mouse macrophages, possibly because of an interaction with Fc receptors. Surprisingly, in CHO cell lines expressing Sn, there is a predominant lysosomal localization. Our results show that the mechanism of Sn internalization and intracellular trafficking is concurrent in the tested species. The cellular background in which Sn is expressed and the type of antibody used can affect the intracellular fate, which in turn can

    Aims To examine the relationship between personality, pregnancy and birth outcomes in adolescents Background Personality has been shown to be a strong predictor of many health outcomes. Adolescents who become pregnant have worse birth outcomes than adults. Design Cross-sectional study using data from the National Longitudinal Study of Adolescent Health (baseline, 1994-1995; follow-up, 2007-2008). Methods The study sample was 6529 girls, 820 of whom reported on pregnancy outcomes for a teenage birth. Personality data was taken from the Mini International Personality Item Pool personality tool, which measures the five-factor personality traits of neuroticism, conscientiousness, intellect/imagination, extraversion and agreeableness. Logistic regression was used to predict teen pregnancy and linear regression was used to predict birth weight and gestational age with adjustment for confounders and stratification by race. Results Agreeableness and intellect/imagination were associated with a reduced likelihood of becoming pregnant as an adolescent, while neuroticism, conscientiousness and extraversion were all associated with an increased likelihood of becoming pregnant. Higher neuroticism was associated with lower birth weight and gestational age among Black girls, but not non-Black. Conscientiousness was associated with lower gestational age among non-Black girls. No relationships were found with extraversion or agreeableness and birth outcomes. Receiving late or no prenatal care was associated with higher intellect/imagination. Conclusions Personality is understudied with respect to pregnancy and birth outcomes compared with other health outcomes. Such research could help professionals and clinicians design and target programs that best fit the characteristics of the population most likely to need them, such as those with high neuroticism.

The moderating role of the built environment was examined.Participants (N = 1217, aged 14-18 years were randomly assigned to four conditions: planning (n = 270, self-efficacy (n = 311, self-efficacy+planning (n = 351, and control (n = 285. The measurement was conducted at baseline (T1, two-month follow-up (T2, and fourteen-month follow-up (T3. Interventions/control group procedures were delivered at T1 and T2. Percent of body fat tissue (measured at T1 and T3 was the main outcome. Social cognitive mediators (self-efficacy and planning were assessed at T1 and T2. The behavioral mediator (MVPA and the presence of built MVPA facilities (the moderator were evaluated at T1 and T3.Similar small increases of body fat were found across the three intervention groups, but the increment of body fat was significantly larger in the control group. On average, differences between control and intervention groups translated to approximately 1% of body fat. Effects of the interventions on body fat were mediated by relevant social cognitive variables and MVPA. A lower increase of body fat was found among intervention group participants who had access to newly-built MVPA facilities.We found no superiority of an intervention targeting two social cognitive variables over the intervention targeting one cognition only.

    Pedicle screw constructs have become the mainstay for surgical correction in patients with spinal deformities. To reduce or avoid the risk of pedicle screw-based complications and to decrease the costs associated with pedicle screw instrumentation, some authors have introduced interval, skipped, and key-vertebral pedicle screw strategies for correction. However, there have been no comparisons of outcomes among these 3 pedicle screw-placement strategies.The aim of this study was to compare the correlative clinical outcomes of posterior correction and fusion with pedicle screw fixation using these 3 surgical strategies.Fifty-six consecutive patients with Lenke type 1 adolescent idiopathic scoliosis were included in this study. Twenty patients were treated with the interval pedicle screw strategy (IPSS), 20 with the skipped pedicle screw strategy (SPSS), and 16 with the key-vertebral pedicle screw strategy (KVPSS). Coronal and sagittal radiographs were analyzed before surgery, at 1 week after surgery, and at the last follow-up after surgery.There were no significant differences among the 3 groups regarding preoperative radiographic parameters. No significant difference was found between the IPSS and SPSS groups in correction of the main thoracic curve (70.8% vs 70.0%; P = 0.524). However, there were statistically significant differences between the IPSS and KVPSS groups (70.8% vs 64.9%) and between the SPSS and KVPSS groups (70.0% vs 64.9%) in correction of the main thoracic curve (P SPSS group was significantly higher than those in the IPSS (P SPSS and KVPSS groups (P SPSS, it can achieve a satisfactory clinical outcome and is more cost-effective.

    Full Text Available ABSTRACT Objective To perform the psychometric evaluation of the Disordered Eating Attitude Scale (DEAS for adolescents. Methods Sample consisted of 1,119 Brazilian adolescents (12-18 years old; 59.6% female studying at technical schools in São Paulo state-Brazil, who answered an online survey with the DEAS, the Eating Attitude Test (EAT-26, and the Restraint Scale (RS. The internal consistency of the DEAS was assessed using Cronbach’s alpha. The convergent validity of DEAS was evaluated by means of Pearson’s coefficient correlation with EAT-26 and RS. The test-retest reliability was evaluated using a sub-sample of 61 adolescents. Known-groups validity was determined by comparing female student mean scores with scores of 33 female adolescents with eating disorders. Results The reliability of the DEAS was 0.79. EAT-26 and RS scores were positively correlated with DEAS scores (EAT: 0.78 for females and 0.59 for males, p < 0.001; RS: 0.63 for females and 0.48 for males, p < 0.001. The DEAS total and subscale scores differentiated students and patients with eating disorders (p < 0.001. The intra-class correlation coefficient for test-retest reliability was 0.87. Conclusion Results indicate that the DEAS adolescent version showed good internal consistency, convergent validity, known-groups validity, and test-retest reliability, suggesting its potential in identifying disordered eating attitudes among adolescents. It could also be helpful in identifying adolescents at risk from eating disorders, assisting in prevention programs.

    In China, the five-year program of undergraduate education for stomatology consists of four years of lecture courses and one year of internship focused on clinical training. Dental schools provide this clinical training either in their own clinics (referred to as the one-stage pattern because all forms of practice are completed together) or by placing students in external clinics usually at non-affiliated hospitals (referred to as the three-stage program because the three primary areas are taught separately). The aims of this study were to investigate differences in teaching effect between the one-stage and the three-stage patterns and to evaluate advantages and disadvantages of the two patterns. A three-section, 31-item questionnaire was designed to assess basic and clinic information about the interns' training and their self-confidence in performing clinical procedures. The survey was administered to graduates who finished the fifth-year internship in 2012-14. Of the 356 individuals invited to participate, 303 graduates who spent their intern years in 43 academic dental institutions returned completed surveys (response rate of 85%). The one-stage group (n=121) reported longer independent operation time than the three-stage group (n=182) (pconfident in oral hygiene instruction and scale and polish (overall median=5), but showed low confidence in rubber dam placement and four other procedures (overall median=2). The one-stage group rated their confidence level higher than the three-stage group on comprehensive skills such as arranging appointments and managing patients and procedures needing long treatment periods such as molar endodontics. The three-stage group showed higher confidence on more specialized procedures such as surgical extractions and suturing. This study found that both of the two intern patterns had advantages and shortcomings in clinical training in various procedures. Combining the two could be a way to improve clinical education in China.

    We performed an in vitro study to investigate the stabilization (i.e. motion reduction) provided by the external spinal fixator (ESF), and to compare the three configurations of the ESF with two internal fixation techniques. Six human cadaveric lumbar spine specimens (L3-S1) were subjected to multidirectional flexibility testing in six configurations: (1) intact, (2) ESF in neutral, (3) ESF in distraction, (4) ESF in compression, (5) translaminar facet screw fixation, and (6) internal transpedicular fixation. Both the ESF and the internal fixation systems stabilized the specimens from L4 to S1. In each testing configuration, pure bending moments of flexion-extension, bilateral axial rotation, and bilateral lateral bending were applied to the uppermost vertebra stepwise to a maximum of 10 Nm. The rigid body motion between the vertebrae was measured using an optoelectronic camera system, and custom software was used to calculate the intervertebral rotations. For each applied motion in all testing configurations, the total range of motion (ROM) of L4-S1 is reported. All three ESF configurations stabilized the spine significantly when compared to the intact specimen. The ESF in compression provided significantly more stabilization in flexion-extension than the two other ESF configurations, but no other significant differences were found between the three ESF modes. In flexion-extension the ESF stabilized the spine significantly when compared with the two internal fixation devices. Only in bilateral lateral bending was the ESF inferior to internal transpedicular fixation in providing stabilization. The results of the present study suggest that the ESF provides a high degree of stabilization for preoperative assessment of selected low back pain patients. Whether other non-mechanical factors affect the pain relief experienced by the patients remains unknown.

    Back pain constitutes a major problem in modern societies. Facet joints are increasingly recognised as a source of such pain. Knowledge about the internal morphology and its changes with age may make it possible to include the facets more in therapeutic strategies, for instance joint replacements or immobilisation. In total, 168 facets from C6/7 and L4/5 segments were scanned in a micro-computed tomography. Image analysis was used to investigate the internal morphology with regard to donor age and gender. Additional data from trabecular bone of the vertebral core allowed a semi-quantitative comparison of the morphology of the vertebral core and the facets. Porosity and pore spacing of the cortical sub-chondral bone does not appear to change with age for either males or females. In contrast, bone volume fraction decreases in females from approximately 0.4 to 0.2 , whereas it is constant in males. Trabecular thickness decreases during the ageing process in females and stays constant in males , whereas trabecular separation increases during the ageing process in both genders. The results of this study may help to improve the understanding of pathophysiological changes in the facet joints. Such results could be of value for understanding back pain and its treatment.

    Since the start of international negotiations on the climate in 1991, the Federal Republic of Germany has supported the process of agreeing on binding limits especially for CO{sub 2} emissions among the industrialised countries under international law, after corresponding commitments had already been agreed upon for CFC emissions. The formation of the Adhoc group Berlin Mandate (AGBM) launched a process of negotiation which aimed to lead to the adoption of a protocol with, among other things, quantified limits and reduction targets for the Annex-I countries; this objective was reconfirmed at the Second Conference of Member States in July '96 in Geneva. The work carried out is documented in this final report. Chapter 2 deals with the fundamental principles of target differentiation. Justifications and possible correction factors are presented and methodological approaches to target differentiation developed. In the subsequent chapters, example calculations are made for different groups of countries (EU, OECD, OECD with selected Eastern European countries). Three different methods of target differentiation are employed: correction factors without sectoral differentiation (Chapter 3), correction factors with sectoral differentiation (Chapter 4) and a division into reduction clusters (Chapter 5). A summary of the results and the conclusions to be drawn can be found in Chapter 6 of this final report. The data collected during the study and the individual results of the example calculations are shown in the Appendices. (orig.)

    Circular dichroism is a spectroscopic technique that is widely used to obtain information about protein structure, and hence is an important tool with many applications, including the characterization of biopharmaceuticals. However, there is a lack of confidence in the technique, arising from an observed lack of comparability in the data obtained by different laboratories, or even different operators. In this study, we set out to determine the extent of comparability in the technique, by comparing the results obtained from identical protein samples by a panel of worldwide laboratories. The laboratories chosen were either national measurement institutes (NMIs) or expert laboratories nominated by an NMI. We also aimed to identify the main factors contributing to any lack of measurement comparability. Data were analysed using PCA and SIMCA methods, and we show these statistical techniques are ideal for analysing large amounts of this type of spectroscopic data. We found a startling lack of comparability among laboratories, but we also found that most of the variability arose from relatively simple problems, which can be avoided by following simple guidelines. We believe that the lack of an absolute reference or measurement traceability in circular dichroism contributes to a lack of confidence in the technique. Main text.

    Full Text Available Distal radius fractures account for 17% of all fractures in adults. The fracture of the lower end of radius crush the mechanical foundation of man‟s most elegant tool, the hand. No other fracture has a greater potential to devastate hand function. Today, o pen reduction of the fracture with internal fixation and closed reduction of the fracture with external fixation, forms the mainstay of the treatment of an uncomplicated distal end radius fracture in a patient unless specifically contraindicated. AIMS AND OBJECTIVES: To compare functional outcome, complications & results of two commonly used surgical methods; Open reduction & internal fixation with volar placed buttress plate and Closed reduction & external fixation with „Jess fixator‟ and internal fixation with „k - wire‟ in volar displaced distal radial fractures. MATERIALS AND METHODS : Total 30 cases were included in the study. 15 patients were treated with Open reduction & internal fixation with volar placed buttress plate and 15 were treated with Closed r eduction & external fixation with „Jess fixator‟ and internal fixation with „k - wire‟ in volar displaced distal radial fractures.

    The present study was designed to examine developmental patterns of identity status change during adolescence and young adulthood through meta-analysis. Some 124 studies appearing in PsycINFO, ERIC, Sociological Abstracts, and Dissertation Abstracts International between 1966 and 2005 provided data. All calculations were performed using the software program, Comprehensive Meta-analysis. Results from longitudinal studies showed the mean proportion of adolescents making progressive identity status changes was .36, compared with .15 who made regressive changes and .49 who remained stable. Cross-sectional studies showed the mean proportion of moratoriums rising steadily to age 19 years and declining thereafter, while the mean proportion of the identity achieved rose over late adolescence and young adulthood; foreclosure and diffusion statuses declined over the high school years, but fluctuated throughout late adolescence and young adulthood. Meta-analyses showed that large mean proportions of samples were not identity achieved by young adulthood. Possible reasons for this phenomenon are explored.

The aim of this study was to assess the state of oral health in children with type 1 diabetes compared with healthy children in 2013-2014 in Hamadan province, Iran. Materials and Methods: The specimens were selected through convenience sampling in two groups. Group one consisted of 80 individuals (5-18 years old; case group, suffering from type 1 diabetes mellitus referred to the Pediatric endocrine clinic. Control group consisted of 80 non-diabetic healthy children who were out- patients of pediatric and orthodontic department of Hamadan dental school. Two groups were similar in age and sex. The data were collected through a questionnaire, medical records and clinical examination. DMFT, dmft, GI and PI indices were assessed in each patient. Data were analyzed using ANOVA and T-test. Results: In spite of similarity in oral hygiene habits in both group, there was no significant difference in mean DMFT and permanent decayed teeth in both groups (P>0.05, but the mean dmft (P<0.008 and primary decayed teeth (P<0.011 in the control group was significantly higher than that of the case group. Also, diabetic patients had significantly more gingival inflammation (P<0.05. The mean PI in the two groups did not differ significantly. Oral hygiene habits were similar in both groups but diabetic patients were significantly referred to dentists with lower frequency then that of control group (P=0.00. Conclusion: The devastating effects of diabetes on the oral health, along with other side effects can be effective in promoting tooth decay and gingivitis in diabetic patients. Unfortunately, oral health care and programmed dental visit were not the priority for the diabetic patient (and parents involved in our study. Therefore, programs to increase awareness and encourage patients for a better control of their oral health in order to diminish diabetes

    Study was planned to evaluate the efficacy of commonly used disinfectants and to study qualitatively and quantitatively the persistence of microflora on the untreated (control group) and the disinfected impression surface after 24 h. Disinfectant systems used were immersion systems like glutaraldehyde, sodium hypochlorite and the ultraviolet chamber. The effect of disinfectant on most commonly used Indian impression materials was carried out in this study and results compared with the most commonly used foreign brands for irreversible hydrocolloid and addition silicone. Impressions were made of 25 healthy volunteers. These were disinfected and incubated in an incubator for 24 h at 37°C for aerobic organisms. The inoculation in nutrient media was done to test the viability of microorganisms that can persist after rinsing and disinfection of the impression surface. The colony forming units were counted and compared with that of control group. Control group of all the impression material samples showed growth of Streptococcus viridans, Diphtheroids, Streptococcus pneumoniae to a greater extent. The growth of Candida albicans, Pseudomonas aerugenosa and Staphyloccus albus was present in all the groups but to a lesser extent. The persistence of the microflora on the impression surface of both the studied brands was similar but the concentration of organisms in the alginate control group was two folds as compared to addition silicone group. Use of ultraviolet chamber gave better results compared to the studied immersion systems. All the disinfection systems were effective in reducing the microbial load with ultraviolet chamber as the most effective.

    Full Text Available Background: Catheterization of Internal Jugular Vein (IJV is commonly attempted to obtain central venous access for hemodynamic monitoring, long term administration of fluids, total parenteral nutrition and hemodialysis in critical care patients. The safe puncture of the IJV is achieved by using anatomical land marks on skin surface. Ultrasound guidance could be beneficial in placing central venous catheters by improving the success rate, reducing the number of needle passes, decreasing access time and decreasing complications. Material and Methods: Sixty critical care patients were selected for IJV cannulation either by land mark technique or by ultrasound guided technique in two groups of thirty each. Results: In our study there was 100% success rate for first attempt cannulation in USG technique and where as it was 83.3% in LMG technique. The mean access time in USG technique was 152.50 ± 63.90 sec as against 323.23 ± 146.19 sec in LMG group. Conclusion: Ultrasound guided technique improves the cannulation of the IJV with respect to safety, rapidity and comfort to the patient during the procedure.

    Circular dichroism (CD) is a spectroscopic technique that is widely used to obtain information about protein structure, and hence is an important tool with many applications, including the characterization of biopharmaceuticals. A previous inter-laboratory study, CCQM-P59, showed that there was a poor level of comparability between laboratories in CD spectroscopy. In a follow-up study reported here, we achieved our goal of demonstrating improved comparability and data quality, primarily by addressing the problems identified in the previous study, which included cell path-length measurement, instrument calibration and good practice in general. Multivariate analysis techniques (principal component analysis and soft independent modelling of class analogies) were shown to be useful in comparing large spectral data sets and in classifying spectra. However, our results also show that there is more work to be done to improve confidence in the technique as the discrepancies observed were partially due to systematic effects, which the statistical approaches do not consider. We therefore conclude that there is a need for an improved understanding of the uncertainties in CD measurement.

    Full Text Available Cellular phones are used in the vicinity of a human head, which absorbs power from antenna radiation. This investigation analyzes the effects of antenna substrate materials on electromagnetic (EM absorption in a human head. Antennas are used in analysis with four different dielectric substrate materials, which are Bakelite, FR4 glass epoxy, Rogers R04003, and Taconic TLC. Moreover, two different thicknesses of each substrate are considered in the experimental setup. The EM absorption associated with two types of cell phone antennas is evaluated in the closed vicinity of the human head model. One of them is planar inverted-F antenna (PIFA, which is used as the internal handset antenna and another one is helical antenna, which is used as external handset antenna. This investigation consists of two different operating frequency bands, GSM 900 MHz and DCS 1800 MHz. The EM absorption in the human head is presented using the peak specific absorption rate (SAR and total absorbed power (TAP by the user. The finite-difference time-domain (FDTD method based on Computer Simulation Technology (CST Microwave studio is utilized in this investigation. The obtained results show that the substrate materials do not effect SAR and TAP values considerably for both antennas, but substrate thickness affects the SAR and TAP values significantly. In addition, the substrate thickness affects the SAR and TAP values significantly in most of the cases Moreover, PIFA produces lower SAR than that of a helical antenna significantly for both GSM and DCS frequency band.DOI: http://dx.doi.org/10.5755/j01.ms.22.3.8889

    Full Text Available The aim in this study is to analyze the current stage of conceptual convergence between Brazilian accounting standards applied to the public sector (NBCTSP and the International Public Sector Accounting Standard (IPSAS. The complexity and range of transactions between public or private sector entities, as a result of market internationalization, demand continuous and dynamic assessment of the events that promote quantitative or qualitative equity changes. For this evaluation process, observing accounting principles and standards is important to guarantee, among other information characteristics, understandability and comparability, thus reducing costs for investors and users in general, in view of the barriers raised by diverse languages, cultures, tax and economic policies. For convergence analysis, the standards’ contents were subject to a comparative study, based on a descriptive analysis, with a view to verifying the existing adherence between Brazilian and international standards applied to the public sector. The results found highlight that different aspects still have to be discussed with a view to an actual convergence with the international standards; the current convergence is partial. The high-quality conceptual exposure of the NBCPSPs is observed though, while the contents of the IPSAS are more focused on operating procedures

    Little is known about the psychosocial functioning of persons who have recovered from dysthymic disorder. Such information might be useful in identifying trait markers for dysthymia, and for guiding continuation and maintenance treatment. We explored this issue using data from the Oregon Adolescent Depression Project, a large community-based study of the epidemiology of psychiatric disorders in a high school population. Four groups of adolescents were identified: 38 with a past history of dysthymic disorder; 217 with a past history of major depressive disorder; 142 with a past history of non-affective disorders; and 1079 with no lifetime history of psychopathology. The groups were compared on an extensive battery of psychosocial variables. The most consistent and diagnostically specific finding was that adolescents with a past history of dysthymic disorder reported having a significantly lower level of social support from friends than each of the other three groups of adolescents. Adolescents with a past history of dysthymic disorder also reported significantly higher levels of depressive, internalizing and externalizing symptoms and daily hassles than adolescents with no lifetime history of psychopathology. In addition, they reported higher levels of depressive symptoms and self-consciousness, but fewer externalizing symptoms than adolescents with a past history of non-affective disorders. These data suggest that adolescents with dysthymic disorder continue to experience significant difficulties in psychosocial functioning even after recovery.

    Background: Studies have shown that adolescents with attention-deficit/hyperactivity disorder (ADHD) have an increased risk of alcohol and substance abuse in adulthood. An unequivocal reason for this association has not yet been identified but it has been shown that pharmacological treatment...... is likely to reduce this risk. Aims: To test whether adolescents with ADHD in pharmacological treatment have a higher prevalence of smoking and use of alcohol and drugs than a matched control group from the general population. The study will also analyse associations between smoking, alcohol and drug use......, drugs and alcohol and the self-report version of the Strengths and Difficulties Questionnaire (SDQ). Results: 21% of ADHD probands vs. 16% controls were daily smokers (P = 0.326). Among alcohol users, 52% of ADHD probands vs. 70% controls confirmed monthly alcohol intake (P = 0.014); 4% of cases...

  5. Global Production Networks and International Inequality: Making a Case for a Meso-Level Turn in Macro-Comparative Sociology

    Directory of Open Access Journals (Sweden)

    Mathew Mahutga

    2015-08-01

    Full Text Available In this article, I extend recent macro-comparative empirical research on the developmental implications of global production networks. I draw from theories of commodity/value chains, global production networks and economic sociology to identify three contending theoretical perspectives for exactly how the developmental returns to network participants should be distributed-cooperation, exploitation and differential gains-and derive testable hypotheses for each. Adding to recent empirical advances for measuring the average network position of firms at the country level, I evaluate these hypotheses by way of dynamic panel regression models of hourly wage rates in the garment and transportation equipment industries. The results suggest that macro-sociological theories linking underdevelopment to the structure of the world-economy, as well as theories of the distribution of the gains from network participation, miss important variation at the industry level. Cooperation provides a poor account of the distribution of the gains from network participation. Instead, both industries appear to distribute the gains from network participation differentially across network participants. However, the extent of this inequality increases, and the garment industry transitions to exploitation, when global production networks become entrenched organizational logics. Variation in the distribution of the returns to network participation is explicable only by accounting for production-network governance as it varies across industries and over time. I conclude by highlighting the analytical utility to macro-comparative sociology of a turn toward the mesa-level of global industries.

    This study presents the results from an interlaboratory sequencing study for which we developed a novel high-resolution method for comparing data from different sequencing platforms for a multi-copy, paralogous gene. The combination of PCR amplification and 16S ribosomal RNA gene (16S rRNA) sequencing has revolutionized bacteriology by enabling rapid identification, frequently without the need for culture. To assess variability between laboratories in sequencing 16S rRNA, six laboratories sequenced the gene encoding the 16S rRNA from Escherichia coli O157:H7 strain EDL933 and Listeria monocytogenes serovar 4b strain NCTC11994. Participants performed sequencing methods and protocols available in their laboratories: Sanger sequencing, Roche 454 pyrosequencing(®), or Ion Torrent PGM(®). The sequencing data were evaluated on three levels: (1) identity of biologically conserved position, (2) ratio of 16S rRNA gene copies featuring identified variants, and (3) the collection of variant combinations in a set of 16S rRNA gene copies. The same set of biologically conserved positions was identified for each sequencing method. Analytical methods using Bayesian and maximum likelihood statistics were developed to estimate variant copy ratios, which describe the ratio of nucleotides at each identified biologically variable position, as well as the likely set of variant combinations present in 16S rRNA gene copies. Our results indicate that estimated variant copy ratios at biologically variable positions were only reproducible for high throughput sequencing methods. Furthermore, the likely variant combination set was only reproducible with increased sequencing depth and longer read lengths. We also demonstrate novel methods for evaluating variable positions when comparing multi-copy gene sequence data from multiple laboratories generated using multiple sequencing technologies.

    Full Text Available Objective: Comprehensive statistics on gynecologic malignancies reported from India are deficient. This study was performed to ascertain the profile of gynecologic cancers reported at our center regarding incidence, histologic subtypes, frequency of involvement at various sites and stage at presentation. We endeavored to compare our data with gynecologic cancers reported at other national and international centers. Materials and Methods: Retrospective review of records of gynecologic cancers obtained from Departments of Pathology and Gynecology, at a tertiary care center, Delhi from January 2000 to December 2009 was performed. Comparison with international data was performed using Fishcher′s exact test and chi square tests. Results: A total of 1315 gynecologic cancers were reported. Cervical malignancies were the commonest at our center as compared to uterine malignancies in data from Surveillance, Epidemiology, and End Results (SEER Program of United States and European Union. All malignancies except cervical cancers affected a younger age group at our center than in the US population. Cervical cancer presented at a relatively more advanced stage, ovarian cancers at more localized stages, whereas uterine cancers presented at similar stages as compared to Western data. Conclusions: Our registry presents composite data from North India. Higher age and advanced stage at presentation of cervical cancers suggests lacunae in screening programs available. Ovarian malignancies were more localized at presentation than in the Western population for which environmental or genetic factors may be causative.

    We have observed 10 interacting galaxy pairs using the Fabry-Perot interferometer GH$\\alpha$FaS (Galaxy H$\\alpha$ Fabry-Perot system) on the $4.2\\rm{m}$ William Herschel Telescope (WHT) at the Observatorio del Roque de los Muchachos, La Palma. We present here the H$\\alpha$ surface brightness, velocity and velocity dispersion maps for the 10 systems we have not previously observed using this technique, as well as the physical properties (sizes, H$\\alpha$ luminosities and velocity dispersion) of 1259 HII regions from the full sample. We also derive the physical properties of 1054 HII regions in a sample of 28 isolated galaxies observed with the same instrument in order to compare the two populations of HII regions. We find a population of the brightest HII regions for which the scaling relations, for example the relation between the H$\\alpha$ luminosity and the radius, are clearly distinct from the relations for the regions of lower luminosity. The regions in this bright population are more frequent in the inte...

    Various definitions are used to define metabolic syndrome in adolescents. This study aimed to compare, in terms of prevalence and differences, five frequently used definitions for this population: International Diabetes Federation, National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP) modified by Cook, pediatric American Heart Association (AHA), World Health Organization, and Jolliffe and Janssen. A sample of 1004 adolescents (12.5-17.0 years) from the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study was considered. The components of the definitions (waist circumference/BMI, plasma lipids, glycemia, and blood pressure) were applied, and definitions were compared by using crosstabs, sensitivity, specificity, and kappa coefficient. The prevalence of metabolic syndrome varied from 1.6 to 3.8% depending on the used definitions. Crosstabs comparing the definitions showed the fewest cases being misclassified (having metabolic syndrome or not) between NCEP-ATP and AHA. Analyses for kappa coefficient, sensitivity, and specificity confirmed this finding.

    The purpose of the present study was twofold: (1) to investigate the effects of sexual orientation (heterosexuals and gay men/lesbians) and gender difference on responses to romantic relationship problems (Exit, Voice, Loyalty, and Neglect [EVLN] responses) and of perceived partner's EVLN responses in Turkey, and (2) to examine whether internalized homophobia was associated with EVLN responses and perceived partner's EVLN responses for gay men and lesbians. Responses to Dissatisfaction Scale-Accommodation Instrument, Internalized Homophobia, and Demographics Information were administered to 187 participants (44 lesbians, 44 gay men, 53 heterosexual women, 46 heterosexual men).The MANCOVA results showed that men reported higher loyalty than women, whereas women presented more exit responses than men. Further, the interactions between gender and sexual orientation on the participants' EVLN responses and on the perceived partner's EVLN responses were significant. With respect to heterosexual women, heterosexual men displayed more loyalty responses. Lesbians had higher scores on loyalty than did heterosexual women. Lesbians also had higher scores on perceived partner's exit response than did heterosexual women and gay men. On the contrary, heterosexual women reported more perceived partner's voice response than lesbians. In addition, lesbians reported higher perceived partner's neglect responses than heterosexual women. Compared to heterosexual women, heterosexual men reported higher perceived partner's exit response. Finally, internalized homophobia was associated with destructive responses for both lesbians and gay men.

    Full Text Available Objective: To compare the neurobehavior of neonates born to adolescent mothers with and without depression during gestation. Methods: This prospective cross-sectional study included healthy term neonates born to adolescent mothers with untreated depression during gestation, without exposure to legal or illicit drugs, and compared them with infants born to adolescent mothers without psychiatric disorders. Maternal psychiatric diagnoses were assessed by the Composite International Diagnostic Interview (CIDI 2.1 and neonatal neurobehavior by the Neonatal Intensive Care Unit Network Neurobehavioral Scale (NNNS at 24 to 72 hours of life. Neurobehavioral outcomes were analyzed by ANOVA adjusted for confounders. Results: 37 infants born to mothers with depression during gestation were compared to 332 infants born to mothers without psychiatric disorders. Infants of mothers with depression had smaller head circumferences. Significant interactions of maternal depression and male gender, gestational age > 40 weeks, regional anesthesia during delivery, vaginal delivery, and infant head circumference ≥ 34 cm were found. Worse performance was noted in the following neonatal neurobehavioral parameters: arousal, excitability, lethargy, hypotonicity, and signs of stress and abstinence. Conclusion: Infants born to adolescent mothers with depression exhibit some behavioral changes in the first days of life. These changes are associated with infant sex, gestational age, type of anesthesia, mode of delivery, and head circumference.

    Full Text Available Abstract Background An inverse social gradient in overweight among adolescents has been shown in developed countries, but few studies have examined whether weight gain and the development of overweight differs among adolescents from different socioeconomic groups in a longitudinal study. The objective was to identify the possible association between parental socioeconomic position, weight change and the risk of developing overweight among adolescents between the ages 15 to 21. Methods Prospective cohort study conducted in Denmark with baseline examination in 1996 and follow-up questionnaire in 2003 with a mean follow-up time of 6.4 years. A sample of 1,656 adolescents participated in both baseline (mean age 14.8 and follow-up (mean age 21.3. Of these, 1,402 had a body mass index (BMI = weight/height2kg/m2 corresponding to a value below 25 at baseline when adjusted for age and gender according to guidelines from International Obesity Taskforce, and were at risk of developing overweight during the study period. The exposure was parental occupational status. The main outcome measures were change in BMI and development of overweight (from BMI = 25. Results Average BMI increased from 21.3 to 22.7 for girls and from 20.6 to 23.6 in boys during follow-up. An inverse social gradient in overweight was seen for girls at baseline and follow-up and for boys at follow-up. In the full population there was a tendency to an inverse social gradient in the overall increase in BMI for girls, but not for boys. A total of 13.4% developed overweight during the follow-up period. Girls of lower parental socioeconomic position had a higher risk of developing overweight (OR's between 4.72; CI 1.31 to 17.04 and 2.03; CI 1.10-3.74 when compared to girls of high parental socioeconomic position. A tendency for an inverse social gradient in the development of overweight for boys was seen, but it did not meet the significance criteria Conclusions The levels of overweight and

    Staphylococcus aureus is a human pathogen that can cause a wide range of diseases. Although formerly regarded as extracellular pathogen, it has been shown that S. aureus can also be internalized by host cells and persist within these cells. In the present study, we comparatively analyzed survival and physiological adaptation of S. aureus HG001 after internalization by two human lung epithelial cell lines (S9 and A549), and human embryonic kidney cells (HEK 293). Combining enrichment of bacteria from host-pathogen assays by cell sorting and quantitation of the pathogen's proteome by mass spectrometry we characterized S. aureus adaptation during the initial phase between 2.5 h and 6.5 h post-infection. Starting with about 2 × 10(6) bacteria, roughly 1450 S. aureus proteins, including virulence factors and metabolic enzymes were identified by spectral comparison and classical database searches. Most of the bacterial adaptation reactions, such as decreased levels of ribosomal proteins and metabolic enzymes or increased amounts of proteins involved in arginine and lysine biosynthesis, enzymes coding for terminal oxidases and stress responsive proteins or activation of the sigma factor SigB were observed after internalization into any of the three cell lines studied. However, differences were noted in central carbon metabolism including regulation of fermentation and threonine degradation. Since these differences coincided with different intracellular growth behavior, complementary profiling of the metabolome of the different non-infected host cell types was performed. This revealed similar levels of intracellular glucose but host cell specific differences in the amounts of amino acids such as glycine, threonine or glutamate. With this comparative study we provide an impression of the common and specific features of the adaptation of S. aureus HG001 to specific host cell environments as a starting point for follow-up studies with different strain isolates and regulatory

    Full Text Available Background: In Germany, a national competence based catalogue of learning objectives in medicine (NKLM was developed by the Society for Medical Education and the Council of Medical Faculties. As many of its international counterparts the NKLM describes the qualifications of medical school graduates. The definition of such outcome frameworks indents to make medical education transparent to students, teachers and society. The NKLM aims to amend existing lists of medical topics for assessment with learnable competencies. All outcome frameworks are structured into chapters, domains or physician roles. The definition of the scholar-role poses a number of questions such as: What distinguishes necessary qualifications of a scientifically qualified physician from those of a medical scientist? Methods: 13 outcome frameworks were identified through a systematic three-step literature review and their content compared to the scholar role in the NKLM by means of a qualitative text analysis. The three steps consist of (1 search for outcome frameworks, (2 in- and exclusion, and (3 data extraction, categorization, and validation. The results were afterwards matched with the scholar role of the NKLM.Results: Extracted contents of all frameworks may be summarized into the components , and . Compared to the included frameworks the NKLM emphasises competencies necessary for research and teaching while clinical application is less prominently mentioned. Conclusion: The scholar role of the NKLM differs from other international outcome frameworks. Discussing these results shall increase propagation and understanding of the NKLM and thus contribute to the qualification of future medical graduates in Germany.

    Why do governments pursue obesity legislation? And is the case of Brazil unique compared with other nations when considering the politics of policy reform? Using a nested analytic approach to comparative research, I found that theoretical frameworks accounting for why nations implement obesity legislation were not supported with cross-national statistical evidence. I then turned to the case of Brazil's response to obesity at three levels of government, national, urban, and rural, to propose alternative hypotheses for why nations pursue obesity policy. The case of Brazil suggests that the reasons that governments respond are different at these three levels. International forces, historical institutions, and social health movements were factors that prompted national government responses. At the urban and rural government levels, receiving federal financial assistance and human resource support appeared to be more important. The case of Brazil suggests that the international and domestic politics of responding to obesity are highly complex and that national and subnational political actors have different perceptions and interests when pursuing obesity legislation.

    前些年大家都在讨论比较教育学科的身份危机,然而近年来世界各国,特别是发展中国家比较教育学科的发展依然繁荣,其生命力何在?笔者重申了作为比较教育方法论框架的国际教育交流论坛这一观点的重要性,认为随着知识经济的发展以及世界的多极化和经济体的多元化发展,今天世界各国的教育更需要在真诚沟通的前提下,在教育理论、观念、价值、制度、政策和实践领域互相交流,在具有跨文化性、发展性和预测性的国际性课题中相互合作。由此可见,把比较教育作为国际教育交流论坛,就可以摆脱比较教育学科身份危机的困境,开拓比较教育研究新的广阔天地。%The identity crisis of Comparative Education was once a great concern a few years ago. But nowadays Comparative Education is still flourishing all over the world, especially in developing countries. Why? The author of this article re-stresses the importance of the methodological framework of Comparative Education as an international education exchange forum. It believes that with the development of knowledge economy, multi-polarization of the world order and diversity of economic powers, there is a greater need to exchange their education theories, ideals, values, systems, policies and practice experiences among all countries based on sincere communication. They need to cooperate with each other in the international research projects with cross-cultural, developmental and prospects nature. Taking Comparative Education as an international education exchange forum will help to overcome its identity crisis and expanding its new research horizon.

    Background. This study aims to compare the outcome of macular hole (MH) surgery with internal limiting membrane (ILM) peeling facilitated by two different vital dyes. Methods. This was a retrospective chart review. The group designated “group-MB” underwent pars plana vitrectomy with ILM peeling facilitated by Membrane-Blue (MB), whereas in “group-MBD,” the vital dye used was Membrane-Blue-Dual (MBD). Results. Seventy-four eyes comprised the study population: 53 in group-MB and 21 in group-MBD. There was no difference in the rate of macular hole closure in group-MB or group-MBD: 71.2% closed MHs compared to 66.7%, respectively (p = 0.7). Postoperative visual improvement was of a higher magnitude in the MBD group compared to the MB group: −0.34 ± 0.81 logMAR versus 0.01 ± 0.06 logMAR, respectively (p = 0.003). Conclusions. In this study, MBD led to better visual results that may be related to better staining characteristics or lesser toxicity compared to MB. PMID:28050275

    2004-01-01

    Obesity in adolescence has increased significantly over the past 30-40 years and a recent international comparison study (13 European countries, Israel and the US) showed that the highest prevalence in adolescents was found in the US (12.6% in 13 year old boys, 10.8% in girls; 13.9% in 15 year old boys and 15.1% in 15 year old girls) and the lowest in Lithuania. This increase in adolescence is a public health concern, because most obese adolescents continue their obesity into adulthood with serious risk for chronic disease. Focus should therefore be on prevention programs that increase healthier patterns of lifestyle and physical activity.

  12. First Steps Toward a Quality of Climate Finance Scorecard (QUODA-CF): Creating a Comparative Index to Assess International Climate Finance Contributions

    Are climate finance contributor countries, multilateral aid agencies and specialized funds using widely accepted best practices in foreign assistance? How is it possible to measure and compare international climate finance contributions when there are as yet no established metrics or agreed definitions of the quality of climate finance? As a subjective metric, quality can mean different things to different stakeholders, while of donor countries, recipients and institutional actors may place quality across a broad spectrum of objectives. This subjectivity makes the assessment of the quality of climate finance contributions a useful and necessary exercise, but one that has many challenges. This work seeks to enhance the development of common definitions and metrics of the quality of climate finance, to understand what we can about those areas where climate finance information is available and shine a light on the areas where there is a severe dearth of data. Allowing for comparisons of the use of best practices across funding institutions in the climate sector could begin a process of benchmarking performance, fostering learning across institutions and driving improvements when incorporated in internal evaluation protocols of those institutions. In the medium term, this kind of benchmarking and transparency could support fundraising in contributor countries and help build trust with recipient countries. As a feasibility study, this paper attempts to outline the importance of assessing international climate finance contributions while describing the difficulties in arriving at universally agreed measurements and indicators for assessment. In many cases, data are neither readily available nor complete, and there is no consensus on what should be included. A number of indicators are proposed in this study as a starting point with which to analyze voluntary contributions, but in some cases their methodologies are not complete, and further research is required for a

    Multilevel models of developmental psychopathology implicate both characteristics of the individual and their rearing environment in the etiology of internalizing problems and disorders. Maladaptive regulation of fear and sadness, the core of anxiety and depression, arises from the conjoint influences of ineffective parasympathetic regulation of emotion and ineffective emotion socialization experiences. In 171 youths (84 female, M = 13.69 years, SD = 1.84), we measured changes of respiratory sinus arrhythmia (RSA) in response to sadness- and fear-inducing film clips and maternal supportive and punitive responses to youths' internalizing emotions. Youths and mothers reported on youths' internalizing problems and anxiety and depression symptoms concurrently and 2 years later at Time 2. Maternal supportive emotion socialization predicted fewer, and punitive socialization predicted more, mother-reported internalizing problems at Time 2 only for youths who showed RSA suppression to fear-inducing films. More RSA suppression to sadness-inducing films predicted more youth-reported internalizing problems at Time 2 in girls only. In addition, less supportive emotion socialization predicted more youth-reported depression symptoms at Time 2 only for girls who showed more RSA suppression to sadness. RSA suppression to sadness versus fear might reflect different patterns of atypical parasympathetic regulation of emotional arousal, both of which increase the risk for internalizing difficulties in youths, and especially girls, who lack maternal support for regulating emotions.

    Previous studies on computer modeling of RF ablation with cooled electrodes modeled the internal cooling circuit by setting surface temperature at the coolant temperature (i.e., Dirichlet condition, DC). Our objective was to compare the temperature profiles computed from different thermal boundary conditions at the electrode-tissue interface. We built an analytical one-dimensional model based on a spherical electrode. Four cases were considered: A) DC with uniform initial condition, B) DC with pre-cooling period, C) Boundary condition based on Newton's cooling law (NC) with uniform initial condition, and D) NC with a pre-cooling period. The results showed that for a long time (120 s), the profiles obtained with (Cases B and D) and without (Cases A and C) considering pre-cooling are very similar. However, for shorter times ( 30 s), Cases A and C overestimated the temperature at points away from the electrode-tissue interface. In the NC cases, this overestimation was more evident for higher values of the convective heat transfer coefficient (h). Finally, with NC, when h was increased the temperature profiles became more similar to those with DC. The results suggest that theoretical modeling of RF ablation with cooled electrodes should consider: 1) the modeling of a pre-cooling period, especially if one is interested in the thermal profiles registered at the beginning of RF application; and 2) NC rather than DC, especially for low flow in the internal circuit.
