A continent-wide detailed geological map dataset of Antarctica.

A dataset to describe exposed bedrock and surficial geology of Antarctica has been constructed by the GeoMAP Action Group of the Scientific Committee on Antarctic Research (SCAR) and GNS Science. Our group captured existing geological map data into a geographic information system (GIS), refined its spatial reliability, harmonised classification, and improved representation of glacial sequences and geomorphology, thereby creating a comprehensive and coherent representation of Antarctic geology. A total of 99,080 polygons were unified for depicting geology at 1:250,000 scale, but locally there are some areas with higher spatial resolution.

Constraining the tectonic evolution of rifted continental margins by U-Pb calcite dating.

We employ U-Pb calcite dating of structurally-controlled fracture fills within crystalline Caledonian basement in western Norway to reveal subtle large-scale tectonic events that affected this rifted continental margin. The ages (15 in total) fall into four distinct groups with ages mainly ranging from latest Cretaceous to Pleistocene. (1) The three oldest (Triassic-Jurassic) ages refine the complex faulting history of a reactivated fault strand originated from the Caledonian collapse and broadly correlate with known rifting events offshore.

Needs ranking: A qualitative study using a participatory approach.

Youth disengagement is a growing concern globally, yet little research has been done to explore participatory approaches that can engage youth as co-creators of community programs that improve their resilience. The primary objective of the study is to report on the results of an innovative participatory approach used in the Eastern and Western Cape provinces, South Africa, to engage vulnerable youth in needs ranking. Data for this paper were collected in three phases.

Adolescent Substance Use Behavior Change Through School Intervention Is Improved by Teacher and School Implementation Support Together, Especially for Girls.

An earlier trial of a school-based, preventative intervention, HealthWise South Africa, demonstrated some efficacy in preventing adolescent drinking and smoking in the Western Cape, South Africa. This was followed by the current implementation trial, which examined how implementation support conditions influenced adolescent drinking and smoking behavior change in the HealthWise intervention. The hybridized implementation-effectiveness trial included 34 schools (n = 2175 students) that provided student data at four waves through Grades 8 to 10.

Rural voices: A social-ecological perspective on factors influencing youth substance use in rural South africa.

Background: Youth can be a positive force for development when provided with the knowledge and opportunities they need to thrive, yet they continue to experience insurmountable challenges, such as poverty and absentee fathers, that prompt them to resort to risk behaviours such as substance use. In rural South Africa, women tend to be the breadwinners and more involved with parenting than men.

Objective: The primary objective of the study was to explore perspectives of rural youth on factors influencing youth participation in substance use.

Profiles of Adolescent Leisure Motivation and Substance Use in the HealthWise South Africa Research Trial: A Person-Centered Approach.

Engaging in intrinsically motivated behaviors, both within and outside of the leisure context, is associated with well-being. However, individuals can be driven by multiple types of motivation simultaneously, and the impact of constellations of leisure motivation is relatively unknown. The current study uses South African adolescents in the HealthWise South Africa efficacy trial (=2,204; =14.

Supporting South African High School Teachers' Implementation of a Prevention Program via Abridged Consultation: Outcomes and Moderators.

Research is lacking on consultation support for school-based evidence-based programs (EBP) intended to prevent youths' risky behaviors in schools in low-resourced settings like high schools surrounding Cape Town, South Africa. Thus, this study's objective was to examine implementation outcomes and moderators of an abridged consultation condition for supporting teachers in better implementing HealthWise, an EBP for preventing youth risky sexual and substance use behaviors. Twenty-one schools with 33 teachers receiving abridged consultation (i.

A weighted bootstrap approach to logistic regression modelling in identifying risk behaviours associated with sexual activity.

The latest population estimates released by Statistics South Africa indicate that 25.03% of all deaths in 2017 in South Africa were AIDS-related. Along with these results, it is also reported that 7.

Trends in HIV risk behaviour of incoming first-year students at a South African university: 2007-2012.

The aim of the research on which this article is based was to understand the behavioural changes of the target student population over time to ensure that future prevention programmes are more effective in changing behaviour. This study reports on quantitative data collected at the University of the Western Cape over a six-year period between 2007 and 2012. All the students attending the orientation sessions and who were willing to complete the anonymous questionnaire during each of the six years were included in the study.

Correlates of sexual activity versus non-activity of incoming first-year students at a South African university.

In order to contribute to the design of more effective programmes to curb the spread of HIV at tertiary institutions, this study compares the profile of students who are sexually active versus those who are not yet sexually active when entering university. The study was conducted among three cohorts of first-year university students at the University of the Western Cape from 2007 to 2009. A range of correlates of sexual activity versus non-activity were explored using logistic regression analysis.

The Dynamic Association between Healthy Leisure and Substance Use in South African Adolescents: A State and Trait Perspective.

South Africa has an increasing adolescent substance use problem, lack of leisure opportunities and resources, and high adolescent discretionary time. How aspects of leisure relate to adolescent substance use is not well understood. Little research has been conducted on the leisure behaviors and experiences of South African adolescents, if and how those behaviors are associated with substance use, and ecological influences on those associations.

Translational Research in South Africa: Evaluating Implementation Quality Using a Factorial Design.

BACKGROUND: HealthWise South Africa: Life Skills for Adolescents (HW) is an evidence-based substance use and sexual risk prevention program that emphasizes the positive use of leisure time. Since 2000, this program has evolved from pilot testing through an efficacy trial involving over 7,000 youth in the Cape Town area. Beginning in 2011, through 2015, we are undertaking a new study that expands HW to all schools in the Metro South Education District.

AIDS fatigue and university students' talk about HIV risk.

Drawing on a qualitative study that included 20 focus group discussions with male and female students at an urban-based university in South Africa, this article reports on perceptions, attitudes and reported behaviour with respect to HIV and AIDS and safer sex in the campus setting, with an aim to better understand how young people are responding to the challenges of HIV and AIDS in contemporary South Africa. The findings demonstrate the gap between reported HIV-prevention knowledge and safer-sex practices among a group of young and educated South Africans. Although the participants reported that students were knowledgeable about HIV and had easy access to condoms on campus, a range of factors mediated their capacity to apply this knowledge to safer-sex practices.
