Physical activity from adolescence to young adulthood: patterns of change, and their associations with activity domains and sedentary time
2021
Background Longitudinal studies demonstrate an average decline in physical activity (PA) from adolescence to young adulthood. However, while some subgroups of adolescents decrease activity, others increase or maintain high or low activity. Activity domains may differ between subgroups (exhibiting different PA patterns), and they offer valuable information for targeted health promotion. Hence, the aim of this study was to identify PA patterns from adolescence to young adulthood; also to explore the associations of (i) changes in PA domains and in sedentary time, (ii) sociodemographic factors, and (iii) self-rated health with diverging PA patterns. Methods The observational cohort study data …
How Do Young Adults Orchestrate Their Multiple Achievement-Related Goals? Associations of Achievement Goal Orientations With Identity Formation and G…
2016
Young adults strive for multiple achievement goals. Frameworks for achievement goal orientations, personal goals, and identity formation have emphasized the role of goal-specific exploration and commitment in the interpretation of goals. However, researchers have yet to combine these different perspectives in an empirical study. Therefore, to explore the processes involved in the selection of multiple goals, the present study investigated the associations of young adults’ achievement goal orientations (mastery-intrinsic, mastery-extrinsic, performance-approach, performance-avoidance, and work-avoidance orientations) with distinct styles of exploring and committing to goals, by considering d…
Relationships Between Career Indecision, Search for Work Self-Efficacy, and Psychological Well-Being in Italian Never-Employed Young Adults.
2017
Although different studies have investigated career choices as cognitive acts of decision-making, non-cognitive components also play an important role. The study tries to develop an empirically based model of career decision-making process linking cognitive (search for work self-efficacy - SWSE) and non-cognitive (psychological well-being - PWB) components. In particular, the study investigates, among 148 never-employed Italian young adults, to what extent the relationship between SWSE and career indecision in terms of lack of readiness (LoR) can be explained by their common relationship with PWB. Results highlighted that SWSE is negatively associated with LoR when considered in absence of …
Mediating Effects of Global Negative Effect Expectancies on the Association between Problematic Cannabis Use and Social Anxiety
2017
The relationship between social anxiety and cannabis use among adolescents and young adults is a highly debated topic. In this cross-sectional study, we tested whether cannabis use expectancies mediated the association between social anxiety and cannabis use severity in a sample of 343 young adults (74.3% male) who used cannabis. They completed self-report measures for the screening of problematic cannabis use (Cannabis Use Problems Identification Test) and social anxiety symptoms (Social Interaction Anxiety Scale and Social Phobia Scale). A multiple mediation analysis was used to test whether marijuana effect expectancies mediate social anxiety effect on problematic cannabis use. Social an…
Rules of Engagement: Family Rules on Young Children’s Access to and Use of Technologies
2018
This chapter reports on a study conducted in seven countries in which young children’s (aged under 8) digital practices in the home were examined. The study explored family practices with regard to access to and use of technologies, tracing the ways in which families managed risks and opportunities. Seventy families participated in the study, and interviews were undertaken with both parents and children, separately and together, in order to address the research aims. This chapter focuses on the data relating to parental mediation of young children’s digital practices. Findings indicate that parents used a narrow range of strategies in comparison to parents of older children, primarily becau…
Young Elderly and Digital Coaching : A Quantitative Intervention Study on Exercise Self-Efficacy
2020
Sport and wellness technology devices are becoming an increasingly relevant topic when discussing health and wellness. This study focuses on the use of a “digital coach”, within a specific population, young elderly people. This research explored how the use of a digital coach would affect self-efficacy related to physical activity and exercise among young elderly. Thisquantitative intervention study provided a digital coaching device to a group of young elderly people ranging from 61-78 in age for 10-weeks. It was found that a digital coach may be useful for this population, particularly in increasing their perceived confidence in exercising independently. However, the participants’ percept…
Biodegradable Metal-Organic Framework-Based Microrobots (MOFBOTs).
2020
Microrobots and metal–organic frameworks (MOFs) have been identified as promising carriers for drug delivery applications. While clinical applications of microrobots are limited by their low drug loading efficiencies and the poor degradability of the materials used for their fabrication, MOFs lack motility and targeted drug delivery capabilities. The combination of these two fields marks the beginning of a new era; MOF‐based small‐scale robots (MOFBOTs) for biomedical applications. Yet, biodegradability is a major hurdle in the field of micro‐ and nanoswimmers including small‐scale robots. Here, a highly integrated MOFBOT that is able to realize magnetic locomotion, drug delivery, and selec…
Sirds veselības pratība un Latvijas veselības žurnāli
2016
Maģistra darbā “Sirds veselības pratība un Latvijas veselības žurnāli”, izmantojot zinātnes komunikācijas, ziņas kā izklaides un mediju pratības teorijas, analizēti Latvijas veselības žurnālos paustie viedokļi par sirds un asinsvadu veselību/slimībām un veikta piedāvāto ārstniecisko metožu analīze. Noskaidrojot vai respondenti ir sirds pratīgi, tika analizēti: raksti veselības žurnālos, aptaujāto respondentu sniegtās atbildes, intervijas ar žurnālu pārstāvjiem un kardiologiem. Pētījumā izmantota novērojuma pētnieciskā metode, kas ļāva fiksēt sirds veselībai veltīto zinātnes komunikācijas pasākumu. Kontenanalīzē, aptaujā, intervijā un novērojumā iegūto datu analīze parāda, ka Latvijas veselī…

Des vestiges de consommation de sel sur le site laténien de Brebières « Les Béliers » (Pas-de-Calais)
2013
Le site de Brebières « Les Béliers » (Pas-de-Calais) a fait l'objet d'une opération de diagnostic couvrant une surface de 60 ha aboutissant à la fouille d'une superficie de 17 ha. Celle-ci a donné lieu à la découverte d'une vingtaine d'enclos fossoyés dont la datation s'échelonne de La Tène C à La Tène D. Près de 2 000 fragments de moules à sel, pour un poids d'environ 6 kg, ont été mis au jour. Implanté à une centaine de kilomètres des côtes et à une vingtaine de kilomètres d'Arras (fig. 1), l'absence de toute trace d'artisanat du sel exclut cependant la possibilité d'un atelier de saunier. Ce site constitue l'un des principaux témoins de la consommation de sel dans le Nord de la France.
