Parents do matter: trajectories of change in externalizing and internalizing problems in early adolescence

This study examined the relative influence of three parenting behaviors (support, behavioral control, and psychological control) and deviant peers on trajectories of externalizing and internalizing problems in early adolescence. A white, working-to-middle-class sample of adolescents and their mothers and fathers in two-earner families participated in a 32-year longitudinal study (N = 109 families). The study began when the adolescents were in sixth grade (M age = 11.5 years). Analyses showed that parents' firm behavioral control seemed to halt the upward trajectory in externalizing problems among adolescents with deviant peers. Initial levels of internalizing problems were higher among adolescents with parents who reported lower levels of behavioral control and among adolescents with deviant peers. This study suggests that parenting exerts an important influence in adolescents' lives and may do so even in the face of potentially negative peer influence.     

Effects of an unsupervised pedometer-based physical activity program on daily steps of adults with moderate to severe asthma: a randomized controlled trial

Supervised exercise has shown benefits for subjects with asthma, but little is known about the effectiveness of unsupervised physical activity on this population. We investigated the effects of a 12-week unsupervised pedometer-based physical activity program on daily steps and on clinical and psychological parameters of adults with asthma. Clinically stable adults with moderate to severe asthma were encouraged to take daily 30-minute walks and were randomized to pedometer and control groups. The pedometer group received pedometers and individualized daily step targets. Changes in daily steps (average of steps taken during six consecutive days), six-minute walk test (6MWT), health-related quality of life, asthma control and anxiety and depression levels were assessed 12 weeks after intervention and 24–28 weeks after randomization. Thirty-seven participants were recruited and 30 completed the intervention. At 12 weeks, the groups differed significantly in daily steps (adjusted average difference, 2488 steps; 95% confidence interval [CI], 803 to 4172; p = 0.005) and in the 6MWT (adjusted average difference, 21.9 m; 95% CI, 6.6 to 37.3; p = 0.006). These differences were not significant 24–28 weeks after randomization. The program was effective in increasing daily steps of adults with moderate to severe asthma 12 weeks after intervention.     

Factors Affecting Student Choice of Career in Science and Engineering: parallel studies in Australia,Canada, China,England, Japan and Portugal

This paper describes parallel studies carried out in six countries which investigated the factors which influence school students towards careers and higher educational studies in the physical sciences or technology. The studies consisted of a common questionnaire survey, supplemented by student interviews. It reveals differences between scientists and non scientists in regard to their preferred learning styles, to the broad factors which were influential in their career choice and to their self perception against different personality types. Many factors are common across a wide range of countries. Implications of these findings for schools, higher education and government are discussed.

A comparison of parent and professional perceptions of children with autism spectrum disorder in Portugal

Improving early intervention in Portugal for children with autism spectrum disorder (ASD) requires parents and professionals to collaborate in assessing and planning intervention programmes. This article analyses parental and professional assessments of children with ASD, in the dimensions of social communication, repetitive behaviours and restricted interests, and sensory processing. The study presents contrasting perspectives from professionals and parents from a range of socio‐academic backgrounds. The sample consists of 136 Portuguese children (aged three to six years old) with ASD and involves children, parents and professionals from across the country. All children, at the time, were in preschool and receiving early special education intervention. Parents and professionals used the Assessment Scale for Children with ASD to complete the assessments. The results show that parents rate children's development and learning more positively compared to professionals; and that this difference is more significant in the field of social communication. Further, parents with higher academic qualifications showed statistically significant differences in comparison with professionals in the social communication dimension. These findings are discussed in relation to the literature and some suggestions are made regarding certain practices related to intervention in early childhood.     

Achieving scientific excellence: An exploratory study of the role of emotional and motivational factors

This study investigates the perceived role of psychological factors in achieving excellence in scientific research. Six outstanding scientists aged 33–42 were interviewed. Data were analyzed inductively resulting in three main dimensions: personality traits and characteristics, psychological skills and processes, and task-specific strategies. Researchers highlighted the importance of emotional factors and motivational processes to achieve and sustain scientific excellence. Flexible coping, emotion regulation, and goal setting were emphasized and described as particularly important in dealing with rejections, setbacks, and team management issues. Persistence and adaptive perfectionism were key individual characteristics which helped participants in nurturing and sustaining motivation. This study suggests that the specific impact of emotional, motivational, and other psychological skills at different stages of excellence development is relevant; yet, further investigation is needed.     

Geoethics: Master’s Students Knowledge and Perception of Its Importance

In the 1990s, the field of geoethics started its development, associated with a set of ethical principles that regulate the profession of geologists in their relationship with society and with nature. Given the importance of this field, but also its youth, 36 higher education students attending a Master’s of Geology course were surveyed (20 were from an educational branch and 16 were from a scientific branch). The questionnaire applied to them aimed to achieve the following goals: (a) to identify the knowledge of the respondents about this new field and to verify their position about the inclusion of geoethics in the curriculum, (b) to understand how they consider the importance of geological knowledge in political decisions and (c) to investigate possible differences in the thinking of the respondents, given the specificities of their educational branches. The study concluded that the field of geoethics is unknown to the majority of the respondents. However, the recognition of its importance was also verified, after getting familiar with the definition of the concept, as well as the need for its inclusion in formal education. The respondents also considered relevant the creation of a deontological code that could provide geologists with ethical guidance. They also considered that geology should influence political decisions, but they did not consistently recognise the limits of its influence, which seems to reveal the need of a deeper understanding of the specific nature of geological knowledge when compared with other sciences. Almost all the results were similar in both groups, but the students from the educational branch offered more elaborate answers about the issues present in the questionnaire.     

Studying activities that take place in speech interactions: a theoretical and methodological framework

The paper proposes a theoretical and methodological framework based on a pluralistic, concerted approach to the study of activities that take place in and through speech interactions. The framework has a general scope, applying to any collective activity taking form through language interactions. It contributes to a fuller understanding of the dynamics of activity and the emergence of the phenomena observed. The framework fits a constructivist and interactionist paradigm. It allows an approach to different dimensions of the activity: communicational, functional, discursive and interlocutory. The theories, models, concepts and methods chosen to address each of the dimensions are presented. From the study of a collaborative philosophical inquiry produced in the first year of a French primary school, we illustrate the use of the framework and show how it can be enriched according to the nature of the activity studied and researchers’ aims.
