Upgraded viscous flow analysis of multi-element airfoils

A description of an improved version of the NASA/Lockheed multi-element airfoil analysis computer program is presented. The improvements include several major modifications of the aerodynamic model as well as substantial changes of the computer code. The modifications of the aerodynamic model comprise the representation of the boundary layer and wake displacement effects with an equivalent source distribution, the prediction of wake parameters with Green's lag-entrainment method, the calculation of turbulent boundary layer separation with the method of Nash and Hicks, the estimation of the onset of confluent boundary layer separation with a modified form of Goradia's method, and the prediction of profile drag with the formula of Squire and Young. The modifications of the computer program for which the structured approach to computer software development was employed are also described. Important aspects of the structured program development such as the functional decomposition of the aerodynamic theory and its numerical implementation, the analysis of the data flow within the code, and the application of a pseudo code are discussed

Reducing Sexual Risk among Racial/ethnic-minority Ninth Grade Students: Using Intervention Mapping to Modify an Evidenced-based Curriculum

Background: Racial/ethnic-minority 9th graders are at increased risk for teen pregnancy, HIV, and STIs compared to their White peers. Yet, few effective sexual health education programs exist for this population. Purpose: To apply IM Adapt—a systematic theory- and evidence-based approach to program adaptation—to modify an effective middle school sexual health education curriculum, It’s Your Game…Keep It Real! (IYG), for racial/ethnic-minority 9th graders. Methods: Following the six steps of IM Adapt, we conducted a needs assessment to describe the health problems and risk behaviors of the new population; reviewed existing evidence-based programs; assessed the fit of IYG for the new population regarding behavioral outcomes, determinants, change methods, delivery, and implementation; modified materials and activities; planned for implementation and evaluation. Results: Needs assessment findings indicated that IYG targeted relevant health and risk behaviors for racial/ethnic-minority 9th graders but required additional focus on contraceptive use, dating violence prevention, active consent, and access to healthcare services. Behavioral outcomes and matrices of change objectives for IYG were modified accordingly. Theoretical methods and practical applications were identified to address these behavioral outcomes, and new activities developed. Youth provided input on activity modifications. School personnel guided modifications to IYG’s scope and sequence, and delivery. The adapted program, Your Game, Your Life, comprised fifteen 30-minute lessons targeting determinants of sexual behavior and healthy dating relationships. Pilot-test data from 9th graders in two urban high schools indicate promising results. Conclusion: IM Adapt provides a systematic theory- and evidence-based approach for adapting existing evidence-based sexual health education curricula for a new population whilst retaining essential elements that made the original program effective. Youth and school personnel input ensured that the adapted program was age-appropriate, culturally sensitive, and responsive to the needs of the new population. IM Adapt contributes to the limited literature on systematic approaches to program adaptation

Asegúrate: an intervention program against cyberbullying based on teachers' commitment and on design of its instructional materials

This article presents the impact on cyberbullying of the Asegúrate program. This educational program is based on the theory of normative social behavior, self-regulation skills,and the beliefs held by adolescents and consists in a whole package of strategies and resources to help teachers to include in the ordinary curricula. The evaluation of Asegúrate was carried out with a sample of 4779 students (48.9% girls) in 5th and 6th grade in primary education and compulsory secondary education (M = 12.76; SD = 1.67) through a quasi-experimental methodology, with two measures over time. The instrument used was the European Cyberbullying Intervention Project Questionnaire. The results show that the involvement in cyberbullying as cyber-victim,cyber-aggressor, and cyber-bully-victim increase without intervention, whereas it diminishes when intervention is carried out by the teachers who have received specific training and have used the didactic Asegúrate package. Additionally, the impact of the intervention on the different types of behaviors was analyzed, and the results show that Asegúrate is more effective with some forms than with others. Consequently, the Asegúrate program is effective for decreasing the prevalence of cyberbullying, but some modifications need to be made to impact on all the different forms it can take.Gobierno de España PSI2017-86723-RGobierno de España PSI2016-74871-

ISICSoo: a class for the calculation of ionization cross sections from ECPSSR and PWBA theory

ISICS, originally a C language program for calculating K-, L- and M-shell ionization and X-ray production cross sections from ECPSSR and PWBA theory, has been reengineered into a C++ language class, named ISICSoo. The new software design enables the use of ISICS functionality in other software systems. The code, originally developed for Microsoft Windows operating systems, has been ported to Linux and Mac OS platforms to facilitate its use in a wider scientific environment. The reengineered software also includes some fixes to the original implementation, which ensure more robust computational results and a review of some physics parameters used in the computation. The paper describes the software design and the modifications to the implementation with respect to the previous version; it also documents the test process and provides some indications about the software performance.Comment: Preprint submitted to Computer Physics Communication

Clinical Sociology and Adolescent Medicine: The Design of a Program

This article describes the uses of sociological theory and knowledge in the design and operation of an in-hospital program for the care of physically ill and injured adolescents. The central tasks of adolescence — resolution of the conflict between autonomy and dependency, the development of intimacy and competence, the ability to take on adult roles, and the development of the self — may be hampered by a total institution which depersonalizes patients and fosters dependency. The development of normative structures which encourage autonomy, continuity of role evelopment, appropriate levels of intimacy, and continued development of the self are encouraged by appropriate modifications of usual hospital routine. Normative support for these modifications is developed through educational programs for house staff (residents and interns), nurses, and others involved in the program. While the article emphasizes sociological concerns, the success of the program depends on contributions from an interdisciplinary team drawn from medicine, nursing, social work, and sociology

Induction of the Novice Teacher in Urban Schools

New teachers entering the urban pre-K-12 school setting require an induction program to perform their teaching duties. Despite modifications to improve an existing induction program, novice teachers in a Midwestern urban school district were underperforming in the classroom, leaving administrators to address new teacher turnover and a disrupted learning process for students. Drawing from Knowles\u27s adult learning theory and state guidelines to fulfill federal legislation mandates for proper induction, this qualitative case study was designed to explore beginning teachers\u27 perceptions of the modifications in the district\u27s induction program. A sample of 8 novice teachers was recruited to participate in open-ended, semi-structured interviews. Thematic analysis and hierarchical coding were used to build themes and capture recurring patterns. Participants\u27 responses suggested that the district\u27s induction program is in accordance with state guidelines; however, the participants voiced that additional program modifications are needed to improve novice teachers\u27 performance in the classroom. Participants requested more classroom management strategies; an understanding of the urban community norms, policies, procedures, building logistics, and the student population; and strategies to communicate effectively with parents. A 4 \u27day professional development workshop was developed to offer skills and strategies specific to the urban experience and school environment to improve novice teachers\u27 performance. This endeavor may contribute to positive social change by increasing the performance of beginning teachers, thus, reducing teacher turnover and increasing student academic performance
