The majority of research on homeless youth has focused on the multitude of problems faced by this vulnerable population. The current study, while acknowledging the hazards of life on the streets, seeks to explore the personal strengths and informal resources street youth rely on to navigate their environments. Qualitative data from seven focus groups conducted with street youth ages 18?24 were analyzed using content analysis. These data, rich with interactions among youth participants, highlight three important themes: developing ?street smarts,?? existence of personal strengths, and informal resources relied upon by youth to survive. Results provide valuable insights into the strengths of homeless youth that can be useful to providers in assessing street youths? service needs and increasi...

Objective: To reduce mental health symptoms and high-risk behaviors and increase social support and service utilization among street-living youth, the authors conducted a pilot study to assess the feasibility of the social enterprise intervention (SEI) at a homeless youth agency. Method: Convenience sampling was used to recruit 16 street-living youth from the agency. SEI participants received 7 months of vocational and small business training and service referrals. A comparison sample of 12 agency youth was used. Results: Findings from independent sample t tests demonstrate that SEI participants displayed significant improvements at 9 months in life satisfaction, family contact, peer support, and depressive symptoms. Conclusions: Preliminary findings suggest that the SEI was feasible within the agency setting and associated with higher mental health and social outcomes. (Contains 3 ...
The current study investigated relations among ethnic similarity in caregiver-therapist pairs of youth participating in Multisystemic Therapy, therapist adherence, and youth long-term behavioral and criminal outcomes. Participants were 1,979 youth and families treated by 429 therapists across provider organizations in 45 sites. Relations were found, independently, and in the presence of ethnic similarity, between adherence and reductions in youth externalizing and internalizing behavior problems 1-year posttreatment and youth criminal charges 4 years posttreatment. Relations between ethnic similarity and outcomes were found only for reductions in youth externalizing behavior problems and not when adherence was included in the model. Adherence ratings were higher, however, in ethnically similar caregiver-therapist pairs, and evidence was ...
Objectives: Many youth with tics experience distress about having tics and how others may perceive them. Such symptoms are often more impairing and distressing than are the tics and negatively impact self-concept, functioning, and quality of life. Although treatments exist that target the frequency and severity of tics, no intervention has been developed that helps youth with tics cope with their condition and limit associated functional impairment and distress. Given this, we developed a cognitive-behaviorally oriented psychotherapy protocol that promotes adaptive coping and resiliency among youth with tics in addressing varied issues commonly experienced by this population. This poster reports data from the Phase I component of this study. Method: Phase I concentrated on developing the t...

The purpose of this study is to examine the cross-ethnic measurement equivalence of the "Child Behavior Checklist" (CBCL) for 6- to 18-year-olds (2001, parent version) using a sample of African American special needs adopted children, along with a comparison group of Caucasian American special needs adopted children. Reliability and multiple sources of postdictive criterion-related validity were analyzed, and a confirmatory factor analysis of the CBCL within and between participating groups was performed. The results indicate that for practical purposes, the CBCL items appear reliable but not valid in terms of assessing the mental health profiles of both African American and Caucasian youth. These findings are significant because they have important implications for the practical utility of the CBCL in the field for adopted youth. (Contains 6 tables.)
Objective: Evidence from adults suggests that changes in thyroid function are associated with the development of bipolar disorder (BD) and severe mood dysregulation. A dysregulation profile based on the Child Behavior Checklist (CBCL-DP) describes a phenotype with severe mood problems in youth. The present study investigated whether altered thyroid functioning in youths is associated with the severe mood dysregulation symptoms characterized by the CBCL-DP. Methods: We analyzed the thyroid function data from 262 children and adolescents (n=262 for serum TSH, n=148 for free triiodothyronine [fT3] and n=153 for free thyroxine [fT4]) with their CBCL-DP composite score. We created and compared high CBCL-DP and low CBCL-DP subgroups with regard to their serum TSH, fT3 and fT4 concentrations as w...

Divided into three sections, this paper briefly presents Kohlberg's theory of moral reasoning; surveys some key research relating childrearing practices to adolescents' social competence, including moral reasoning; and reports research findings concerning the value systems adolescents develop. The first section characterizes preconventional, conventional, and postconventional morality and explores ways of promoting the development of a mature concept of justice, which includes role taking and living in a "just community." The second section focuses on aspects of social learning, which include authoritative parenting, inductive discipline, argumentative discourse, and tradition-based upbringing. In addition, this section explores socialization practices that hinder the development of mature moral reasoning. Focusing initially on characteristics of alienated youth and parental influences on such youth, the third section describes ...
Given the important role of parent-youth communication in adolescent well-being and quality of life, we sought to examine the relationship between specific communication variables and youth perceived quality of life in general and as a deaf or hard-of-hearing (DHH) individual. A convenience sample of 230 youth (mean age = 14.1, standard deviation = 2.2; 24% used sign only, 40% speech only, and 36% sign + speech) was surveyed on communication-related issues, generic and DHH-specific quality of life, and depression symptoms. Higher youth perception of their ability to understand parents' communication was significantly correlated with perceived quality of life as well as lower reported depressive symptoms and lower perceived stigma. Youth who use speech as their single mode of communication ...

The current status of at-risk and adjudicated youth with behavioral challenges provides a context for addressing needed future directions for research and practice in fields that impact this population. This context includes the myriad characteristics and complex needs of these youth, the programs and services currently available in communities and secure settings, and youth outcomes following incarceration. Recent and emerging national, state, and local initiatives and the benefits that have been realized or are anticipated from their application are presented. The challenges to achieving and sustaining these systems changes are then discussed. The paper concludes with recommendations for future research and practice, based on the issues raised in this special issue and elsewhere. (Contains 1 endnote.)
This longitudinal study examined a model of early school achievement in reading and math, as it varies by socioeconomic context, using data from the NICHD Study of Early Child Care and Youth Development. A conceptual model was tested that included features of family stress, early parenting, and school readiness, through both a single-group analysis and also a multiple-group analysis. Latent profile analysis was used to identify subgroups of more advantaged and less advantaged families. Family stress and parenting were shown to operate differently depending on the socioeconomic context, whereas child-based school readiness characteristics were shown to operate similarly across socieodemographic contexts. Implications for intervention are discussed.
We present a study of the mid-infrared properties and dust content of a sample of 27 HII ``blobs'', a rare class of compact HII regions in the Magellanic Clouds. A unique feature of this sample is that even though these HII regions are of high and low excitation they have nearly the same physical sizes ~1.5-3 pc. We base our analysis on archival 3-8 microns infrared imagery obtained with the Infrared Array Camera (IRAC) on board the Spitzer Space Telescope. We find that despite their youth, sub-solar metallicity and varied degrees of excitation, the mid-infrared colors of these regions are similar to those of typical HII regions. Higher excitation ``blobs'' (HEBs) display stronger 8 micron emission and redder colors than their low-excitation counterparts (LEBs).
Lack of access to basic education leads to diminished individual and national capabilities, therewith furthering cycles of poverty. An equitable education system meeting basic learning needs represents not only a human right, but also a means for reducing poverty, promoting productivity, and sustaining development. The Government of China--the most populous developing nation, the majority of whose citizens live in rural areas--has been committed to universalizing nine-year compulsory education among school-aged children and eliminating illiteracy among youths and adults aged 15-45. This study examines lessons learned from China's efforts in these areas. It also reports on current challenges and trends in a new national initiative for achieving high-quality universal basic education by the year 2007.
This study examined the relationship between the 1997 UPE policy and regional educational and poverty inequality and its impact on lifelong learning through a one-year field based critical ethnography in Uganda, between June 2007 and May 2008. It drew on the Government's assumption that through UPE the twin goals of the universalisation of primary education and lifelong learning would be attained. This led to the concentration of resources away from higher education, secondary education, and lifelong learning to primary education. This 'UPE centric' approach ignored the precarious situation of the large number of illiterate children, youths and adults who have never accessed UPE or dropped out without attaining literacy and numeracy skills. This paper will clarify the relationship between ...
Children with attention-deficit/hyperactivity disorder (ADHD) often have poor relationships with peers. However, research on this topic has predominantly focused on boys. This study considered child gender, ADHD status, and dimensionally assessed conduct problems as predictors of peer relationship difficulties. Participants were 125 children (ages 6-10; 67% male), 63 with clinical diagnoses of ADHD and 62 non-ADHD comparison youth. Conduct problems were reported by teachers and observed in a lab playgroup. Peer relationships were assessed by parent report, teacher report, and peer sociometric nominations in the playgroup. Results suggested that children with ADHD, as well as those with high conduct problems, displayed more impaired peer relationships than did comparison children and those ...
ObjectiveInjury is the leading cause of death among American youth, killing more 11-year-olds than all other causes combined. Children with symptoms of externalizing behavior disorders such as attention-deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) may have increased risk. Our aims were to determine: (1) whether increasing symptoms of ADHD and CD associate positively with injuries among a community sample of fifth graders; and (2) whether symptoms of ADHD and CD have a multiplicative rather than additive association with injuries among the sample. MethodsData were collected from 4745 fifth graders and their primary caregivers participating in Healthy Passages, a multisite, community-based study of pediatric health risk behaviors and health outcomes. The primary outcome wa...

This paper aims to estimate the prevalence of cigarette smoking among students in Vietnam ages 13-15 and examines its relationship with compositional and contextual factors. The data used in this paper were obtained from the 2007 Global Youth Tobacco Survey conducted in nine provinces in Vietnam. A multilevel logistic regression model was applied to analyse the association between the current incidence of cigarette smoking and factors on both the individual and school level. The prevalence of cigarette smoking among students was 3.3% overall. The prevalence of smoking among male students (5.9%) was higher than that among females (1.2%). Parental smoking was a significant risk factor for smoking among the students. Having a friend who smoked was the strongest predictor of smoking status amo...
The dramatic increase in diagnostic rates of bipolar disorder in children and adolescents in the USA has led to an intense interest in the phenomenology of the disorder. Here we present data from a newly-developed instrument to assess episodic mania-like symptoms in youth in a large population-based sample (N?=?5326) using parent- and self-report. We found that a substantial proportion of children screened positive for having episodes of ?going high? and were at an increased risk for morbidity and impairment. Using factor analysis, we identified that episodic mania-like symptoms comprised two dimensions: An under-controlled dimension that was associated with significant impairment, and a low-risk exuberant dimension. Using latent class analysis, we identified a small group of children scor...
Participation in conventional politics, such as elections, membership of organizations and political parties, is relatively low among young adults of ethnic minority background. Instead, engagement seems to find its way through aesthetic and other expressive channels of influence drawing on new technologies, impulses from transnational youth culture traditions, and both street riots and less conflictual actions. The aim of this article is to grasp a potential social movement in the making, by exploring the processes of articulation through which young people from immigrant families in Norway express their political engagement. The phenomenon of articulation is understood as a process comprising three steps or modes: (i) becoming conscious; (ii) generating expressions and (iii) collective a...
In Japan, the term mizumizushii is used to express beauty. This term mizumizushii is an adjective involving factors for a variety of `beauties full of the feeling of vitality' such as youthful, fresh, watery, dewy and the like. The exact choice of words depends on the circumstances. Mizumizushii-looking skin represents the skin that looks wet with the moisture contained in it and that has a good gloss. However, according to our research carried out using a Corneometer, almost no relationship was found between skin actually including a large amount of moisture in the stratum corneum and mizumizushii-looking skin. We elucidated the `apparently mizumizushii-looking skin,' and tried to develop makeup products having the function of making the skin look mizumizushii, which is to be one of the f...
In spite of recent education reform and reorganization efforts requiring the use of research-based methods, the fundamental elements of an effective program for children and youth with emotional and behavioral disorders (EBD) have not been succinctly identified. This article presents the essential features of programs for students with EBD. Program elements include (a) qualified and committed professionals, (b) utilitarian environmental supports, (c) effective behavior management plans, (d) valid social skill and social interpretation training and social interaction programs, (e) proven academic support systems, (f) strong parent- and family-involvement programs, (g) coordinated community support mechanisms, and (h) ongoing evaluation of essential program components and student outcomes and progress. A justification for the program and a comparison of the proposed program with existing models is included in the discussion. (Contains 1 figure.)
Seven years ago 164 governments, together with partner organizations from around the world, made a collective commitment to dramatically expand educational opportunities for children, youth, and adults by 2015. Participants at the World Education Forum in Dakar, Senegal, endorsed a comprehensive vision of education, anchored in human rights, affirming the importance of learning at all ages and emphasizing the need for special measures to reach the poorest, most vulnerable and most disadvantaged groups in society. This sixth edition of the "Education for All (EFA) Global Monitoring Report" assesses the extent to which these commitments are being met. There is clearly a "Dakar effect," evidence that rallying around common goals can mobilize countries to empower individual lives. Partly because of the abolition of tuition fees, more children are enrolled in school than in 2000, with the sharpest increases in the regions farthest from the goals set in Dakar. Many ...

Dimensional variability studies and published dimensional variability standards have been used by the foundry industry for years as an indicator of the casting process` ability to produce uniform parts. These studies are an extremely useful tool in the continuous ``dimensional dialogue`` between foundries and customers. The nature of these studies, and of the current tolerancing systems used by casting designers, leaves room for some misinterpretation and misuse of these study results. This paper contains two important discussions. The first part explains exactly what these studies represent. Following this is a brief explanation on dimensional and geometric tolerances and how they communicate dimensional requirements.

Objective: Results of reliability and agreement studies are intended to provide information about the amount of error inherent in any diagnosis, score, or measurement. The level of reliability and agreement among users of scales, instruments, or classifications is widely unknown. Therefore, there is a need for rigorously conducted interrater and intrarater reliability and agreement studies. Information about sample selection, study design, and statistical analysis is often incomplete. Because of inadequate reporting, interpretation and synthesis of study results are often difficult. Widely accepted criteria, standards, or guidelines for reporting reliability and agreement in the health care and medical field are lacking. The objective was to develop guidelines for reporting reliability and...

Terror management theory (TMT) proposes that people who are reminded of their mortality should be motivated to defend their cultural worldview. Studies 1 and 2 examined whether the TMT worldview defence-buffering effect found in Western cultures could be generalized to Asians in Taiwan. No such effect was found in the present studies. This non-significant result was robust when either a stronger distraction task was used (study 1) or when a subliminal manipulation of mortality salience was utilized (study 2). A meta-analysis, including 24 TMT experiments in East Asia, was also conducted (study 3). The average effect size (d = 0.11, r = 0.055) of worldview defence among these experiments was not significantly different from zero. Study 4 found that mortality salience manipulation also did n...

This report presents the data and results of a site specific case study comparing costs of an overhead line with an underground circuit traversing the same route. The costs used for the overhead line are actual numbers for a line scheduled to be built by a utility. The underground circuit costs were developed using the same criteria of line rating, contingencies, and location. Often cost comparisons between overhead and underground lines are made using figures taken from studies with widely varying assumptions. This project attempts to provide a comparison by studying the costs of overhead and underground lines following the same route and using the same design assumptions. Caution must be used, however, in extending the results of this study beyond its original intent. It is site-specific and may be representative of only one area of the country. 9 refs., 23 figs., 18 tabs.
The synapsin III gene, SYN3, which belongs to the family of synaptic vesicle-associated proteins, has been implicated in the modulation of neurotransmitter release and in synaptogenesis, suggesting a potential role in several neuropsychiatric diseases. The human SYN3 gene is located on chromosome 22q12-13, a candidate region implicated in previous linkage studies of schizophrenia. However, association studies of SYN3 and schizophrenia have produced inconsistent results. In this study, four SYN3 SNPs (rs133945 (-631 C>G), rs133946 (-196 G>A), rs9862 and rs1056484) were tested in three sets of totally 3759 samples that comprise 655 affected subjects and 626 controls in the Irish Case-Control Study of Schizophrenia (ICCSS), 1350 samples incorporating 273 pedigrees in the Irish Study of High D...

Accurate engineering cost estimates are critical in developing bids for new work, and for effective resource allocation and project control. This study reports on design estimating methods found in the literature, and on the results of two empirical studies of how estimating techniques are used in professional practice and their accuracy. The study found great reliance on a classic {open_quotes}activity analysis{close_quotes} approach to estimating design resources, and significant hazards in commonly used parametric techniques. The study found that project managers expect their estimates to be accurate (with 80% confidence interval) of between -10% to +25%. The study also found that actual bids between engineering firms had a much greater range (-40% to +45%) than can be explained by accuracy. Perhaps most importantly the study found that none of the sampled ...
