How personal well-being of adolescents changes over the high school period is not entirely clear in the scientific literature. Using 15 positive youth development (PYD) attributes as indicators of well-being, the current study investigated the related developmental trajectories among a large sample of Hong Kong adolescents from Grade 7 to Grade 12. Individual growth curve modeling revealed that...

A 2-wave survey study among 1173 10–14-year-olds tested the longitudinal contribution of secrecy from parents to psychosocial and behavioral problems in adolescence. Additionally, it investigated a hypothesized contribution of secrecy from parents to adolescent development by examining its relation with self-control. Results showed that keeping secrets from parents is associated with substantia...

Before the development of the germ theory in the late 19th century, infectious illnesses were largely uncontrollable and caused significant mortality. Implementing public hygiene, preventive, and treatment interventions created remarkable improvements in population health. Today's U.S. public health crises involve threats to health and human capital evidenced by multiple indicators of deteriora...

METHODS Twenty two patients aged 14-18 years participated in motivational interviewing sessions during a six month intervention. The effects of the intervention on HbA1c and a range of psychological...

We conducted 2 longitudinal meditational studies to test an integrative model of goals, stress and coping, and well-being. Study 1 documented avoidance personal goals as an antecedent of life stressors and life stressors as a partial mediator of the relation between avoidance goals and longitudinal change in subjective well-being (SWB). Study 2 fully replicated Study 1 and likewise validated av...

Existing compact models for memristive devices (including RRAM and CBRAM) all suffer from issues related to mathematical ill-posedness and/or improper implementation. This limits their value for simulation and design and in some cases, results in qualitatively unphysical predictions. We identify the causes of ill-posedness in these models. We then show how memristive devices in general can be m...

An algorithm that stores the prime implicates of a propositional logical formula in a trie was developed in [10]. In this paper, an improved version of that pi-trie algorithm is presented. It achieves its speedup primarily by significantly decreasing subsumption testing. Preliminary experiments indicate the new algorithm to be substantially faster and the trie based subsumption tests to be cons...

BACKGROUND Procrastination is a prevalent and problematic phenomenon that has mostly been studied in the domain of academic behavior. The current study shows that procrastination may also lead to harmful outcomes in the area of health behavior, introducing bedtime procrastination as an important factor related to getting insufficient sleep and consequently affecting individual well-being. Bedti...

Unmanned aerial vehicles, or 'drones', appear to offer a flexible, accurate and affordable solution to some of the technical challenges of nature conservation monitoring and law enforcement. However, little attention has been given to their possible social impacts. In this paper, I review the possible social impacts of using drones for conservation, including on safety, privacy, psychological w...

An adolescent's subjective experiences of mindfulness were explored in a single case study of a 17-year-old female. Data were created by means of 'mindfulness sessions', unstructured interviews, creative expression, journals and field notes. The data were analysed and interpreted using a combination of typological and interpretive analysis strategies. Findings are presented within a conceptual ...
