Operational and research aspects of a radio-controlled model flight test program

The operational and research aspects of a subscale, radio-controlled model flight test program are presented. By using low-cost free-flying models, an approach was developed for obtaining research-quality vehicle performance and aerodynamic information. The advantages and limitations learned by applying this approach to a specific flight test program are described. The research quality of the data acquired shows that model flight testing is practical for obtaining consistent and repeatable flight data

Solar Terrestrial Relations Observatory (STEREO) Mission and Concept of Operations

The Solar Terrestrial Relations Observatory (STEREO) is a new NASA mission designed to increase the understanding of the origin and consequences of coronal mass ejections (CMEs). The mission will consist of two identical spacecraft at approximately lAU from the Sun: one drifting ahead of the Earth and one behind. Simultaneous image pairs will be obtained by the spacecraft at gradually increasing angular separations over the course of the 2-year mission. The spacecraft launch date is scheduled for 2003. The concept of operations for this mission consists of independent and decoupled instrument and spacecraft bus operations. The Science Operations Teams will generate the instrument commands to accomplish the science objectives, and the STEREO Mission Operations Team (MOT) will support the spacecraft bus. All spacecraft servicing, including commanding and science data recovery, will occur during a daily ground track with the Deep Space Network. All science data will be flowed in near real-time to the Science Operations Center via the Internet. During the normal operations phase of the mission, each track will run autonomously with a small MOT to conduct planning and assessment tasks. The spacecraft and ground system will be highly autonomous, making this mission ideal for lights out operations

Core Beliefs, Self-Perception, and Cognitive Organization in Depressed Adolescents

The relationships between cognitive products (e.g., self-perception) and cognitive structure (or organization) in clinically depressed adolescents and nonpsychiatric controls (average age = 14.68) were examined. Adolescents with major depressive disorder showed significantly higher scores than did controls on the Young Schema Questionnaire domains of Disconnection, Impaired Autonomy, and Impaired Limits. These individuals also demonstrated poorer self-concept than controls on scholastic abilities, social acceptance, athletic competence, physical appearance, job competence, behavioral conduct, and global self-worth, as well as perceptions of limited social networks. The organization of self-referent adjectives was more tightly interconnected for negative content and less interconnected for positive content in depressed adolescents than in nonpsychiatric controls. Specificity of cognitive organization to themes of interpersonal and achievement beliefs/self-perceptions was also found, particularly for positive content. Implications of the findings for the cognitive vulnerability model of depression and future directions are discussed

Improving Access and Mental Health For Youth Using Smart Technologies

The overall objective of this research is to evaluate the use of a mobile health smartphone application (app) to improve the mental health of youth between the ages of 14 and 25 years, with symptoms of anxiety and/or depression. This project includes 122 youth who are accessing outpatient mental health services at one of three hospitals and two community agencies. The youth and care providers are using the Smart technology to enhance care. The technology uses mobile questionnaires (QnairesTM) to help promote self-assessment and track changes to support the plan of care. The youth were provided a smartphone and talk/text/data plan, if needed. The majority of participants identified themselves as Caucasian (73.5%). Expectedly, the demographics revealed that Anxiety Disorders and Mood Disorders were highly prevalent within the sample (73.6% and 66.9% respectively). Findings from the qualitative summary established that both staff and youth found having a smartphone and data plan beneficial. Demographic variables such as age, sex, mental health and physical health did not predict which youth were more likely to use the application

Improving Access and Mental Health for Youth Through Virtual Models of Care

The overall objective of this research is to evaluate the use of a mobile health smartphone application (app) to improve the mental health of youth between the ages of 14–25 years, with symptoms of anxiety/depression. This project includes 115 youth who are accessing outpatient mental health services at one of three hospitals and two community agencies. The youth and care providers are using eHealth technology to enhance care. The technology uses mobile questionnaires to help promote self-assessment and track changes to support the plan of care. The technology also allows secure virtual treatment visits that youth can participate in through mobile devices. This longitudinal study uses participatory action research with mixed methods. The majority of participants identified themselves as Caucasian (66.9%). Expectedly, the demographics revealed that Anxiety Disorders and Mood Disorders were highly prevalent within the sample (71.9% and 67.5% respectively). Findings from the qualitative summary established that both staff and youth found the software and platform beneficial

Obsessive–compulsive disorder with and without tics in a clinical sample of children and adolescents

The purpose of this study was to discriminate subtypes of obsessive-compulsive disorder (OCD) in a clinical sample of children and adolescents. Sixty OCD patients were assessed in two outpatient psychiatric clinics; 15 patients had a lifetime history of tics and 45 patients had no tic history. Interviews were conducted with the patients and their parents by a child psychiatrist using the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). The symptom checklist of the CY-BOCS was used to categorize obsessions and compulsions. Discriminant function analysis was used to compare the two groups in their symptomatology. There was no difference between the two groups in seven obsession categories. However, there was a significant difference between the two groups in seven compulsion categories. Ordering, hoarding, and washing compulsions were more common in those with no tic history. The results indicate that tic-related OCD may be differentiated from non-tic-related OCD early in life by the presence or absence of certain compulsive symptoms.

Study of the distribution of Malassezia species in patients with pityriasis versicolor and healthy individuals in Tehran, Iran

BACKGROUND: Pityriasis versicolor is a superficial infection of the stratum corneum which caused by a group of yeasts formerly named pityrosporium. The taxonomy of these lipophilic yeasts has recently been modified and includes seven species referred as Malassezia. The aim of this study is to compare the distribution of Malassezia species isolated from pityriasis versicolor lesions and those isolated from healthy skins. METHODS: Differentiation of all malassezia species performed using morphological features and physiological test including catalase reaction, Tween assimilation test and splitting of esculin. RESULTS: In pityriasis versicolor lesions, the most frequently isolated species was M. globosa (53.3%), followed by M. furfur (25.3%), M. sympodialis(9.3%), M. obtusa (8.1%) and M. slooffiae (4.0%). The most frequently isolated species in the skin of healthy individuals were M. globosa, M. sympodialis, M. furfur, M. sloofiae and M. restricta which respectively made up 41.7%, 25.0%, 23.3%, 6.7% and 3.3% of the isolated species. CONCLUSIONS: According to our data, M. globosa was the most prevalent species in the skin of healthy individuals which recovered only in the yeast form. However, the Mycelial form of M. globosa was isolated as the dominant species from pityriasis versicolor lesions. Therefore, the role of predisposing factors in the conversion of this yeast to mycelium and its subsequent involvement in pityriasis versicolor pathogenicity should be considered

'It's Just More Acceptable to Be White or Mixed Race and Gay Than Black and Gay': The Perceptions and Experiences of Homophobia in St. Lucia

Lesbian, gay and bisexual (LGB) individuals come from diverse cultural groups with differing ethnic and racial identities. However, most research on LGB people uses white western samples and studies of Afro-Caribbean diaspora often use Jamaican samples. Thus, the complexity of Afro-Caribbean LGB peoples’ experiences of homophobia is largely unknown. The authors’ analyses explore experiences of homophobia among LGB people in St. Lucia. Findings indicate issues of skin-shade orientated tolerance, regionalized disparities in levels of tolerance towards LGB people and regionalized passing (regionalized sexual identity shifting). Finally, the authors’ findings indicate that skin shade identities and regional location influence the psychological health outcomes of homophobia experienced by LGB people in St. Lucia

Social distance between local residents and African-American expatriates in the context of Ghana's slavery-based heritage tourism

This paper explores the social distance between local residents and African-Americans who have settled in Ghana since the 1960s. Data generated from in-depth interviews suggest the African-American expatriates felt their proximity to collective slave memory or particularly slavery heritage conferred on them certain rights to exclude local residents who are more susceptible to forgetting the past. By appropriating traces of the past, the African-American expatriates provide a range of tourism services, albeit to visitors they believed subscribed to socially constructed meanings elicited at slave sites. The study suggests explicit recognition of African-American expatriates in the levels of contestations that result from slavery-based heritage tourism
