Research and Development Expenditures and Economic Growth in the EU: A Panel Data Analysis
2016
Abstract The main aim of the paper is to investigate the empirical relationship between research and development (R&D) expenditures and economic growth in the European Union member states in the period of 2000–2013. The empirical analysis is based on panel data regressions. The estimated model is the production function type standard growth model extended with R&D stock variable. The results show a statistically significant impact of R&D expenditures on the economic growth in the EU countries. The significance for R&D coefficient remains robust to different sub-periods, but the level of significance decreases as a sub-sample of new EU countries was considered.
Peer group influence and selection in adolescents' school burnout : A longitudinal study
2008
The present study investigated the extent to which peer group similarity in school burnout is due to peer group influence and the extent to which it is due to peer group selection. Moreover, the roles of academic achievement and gender in school burnout were examined. A total of 611 ninth graders were examined at the beginning of the final term of comprehensive school, and 614 were examined at the end of the final term. The results of the Multilevel Latent Growth Modeling showed that peer group influence was responsible for peer group similarity, but no evidence was found for peer group selection. The results showed further that high academic achievement protected group members against an i…
From stationary state to endogenous growth: International trade in the mathematical formulation of the Ricardian system
2015
In his 1814–15 correspondence with Malthus and in his Essay on Profits, Ricardo championed the free importation of wage goods as a highly effective growth-enhancing policy. In order to capture this aspect in the mathematical formulation of the Ricardian system first introduced by Pasinetti in 1960 in the context of a closed economy, we produce a variant of that model where the economy is a small open one. We show that this economy is characterised by endogenous growth since the growth rate is bounded from below and we locate two thresholds concerning the allocation of labour among the two sectors of the economy and the pattern of international trade.
Economic Growth and Religious Production Efficiency
2005
During the past few years, empirical economic growth modeling has emerged by constructing and testing numerous model and explanatory variable alternatives. One of the most promising recent idea consists that also religious aspects should be included as explanatory variables into economic growth models, therefore capturing influences of culture, moral and ethics. Moral institutions and ethics affect the economic development, as for example, trust and honesty are essential requirements for emerging economic activity. Religious activities and beliefs are documented over a long time period in many Western economies, making quantitative empirical time series data available. Following the idea an…
Development of internalizing symptoms during adolescence in three countries: the role of temperament and parenting behaviors
2022
AbstractThis longitudinal study examined the unique and joint effects of early adolescent temperament and parenting in predicting the development of adolescent internalizing symptoms in a cross-cultural sample. Participants were 544 early adolescents (T1: Mage = 12.58; 49.5% female) and their mothers (n = 530) from Medellín, Colombia (n = 88), Naples, Italy (n = 90), Rome, Italy (n = 100) and Durham, North Carolina, United States (African Americans n = 92, European Americans n = 97, and Latinx n = 77). Early adolescent negative emotionality (i.e., anger and sadness experience), self-regulation (i.e., effortful control), and parent monitoring and psychological control were measured at T1. Ad…
School-Age Children's Actual Motor Competence and Perceived Physical Competence: A 3-Yr Follow-up.
2022
Purpose This study examined school-aged children’s actual motor competence (MC) and perceived physical competence (PC) over three years along with the covariate effects of gender and body mass index (BMI). Methods Participants were 1 121 (girls 573, boys 548) children (Mage 11.26 ± .32) from 35 randomly selected public schools across Finland. MC was assessed using three movement tests targeting locomotor, stability, and object control skills, and PC was assessed using the sport competence subscale of the Physical Self-Perception Profile via four-phase monitoring. Results MC and PC remained stable over time. Of the three variables, locomotor skills showed the strongest association with PC. L…
Long-term determinants of changes in television viewing time in adults: Prospective analyses from the Young Finns Study
2018
Purpose The long-term effects of sociodemographic and health characteristics on television viewing (TV) time changes have not been identified in adulthood. We aimed to examine the modifiable and non-modifiable determinants of changes in TV-time in young adults over 10 years. Methods Participants (N = 2929) aged 24-39 years were recruited between 2001 and 2011 from the Cardiovascular Risk in Young Finns Study. Data were collected using questionnaires and a medical examination. The determinants of changes in TV-time were estimated using latent growth modeling for men and women separately. Results For men, inverse associations with initial levels of TV-time were observed for students becoming …
Longitudinal physical activity trajectories from childhood to adulthood and their determinants: The Young Finns Study
2018
Determining lifelong physical activity (PA) trajectories and their determinants is essential to promote a physically active lifestyle throughout the life-course. We aimed to identify PA trajectories from childhood to midlife and their determinants in a longitudinal population-based cohort. This study is a part of the Cardiovascular Risk in Young Finns Study. From 1980, a population-based cohort (N = 3596; 1764 boys/1832 girls, age 3-18 years) has been followed up for 31 years. PA indices were formed based on self-reported data (between age 9-49 years) on frequency, duration, and intensity of leisure (during childhood) or high-intensity (at later age) PA and on sports club participation/comp…
Does clinically relevant psychopathology in adolescents necessarily require treatment or does it “grow out”?
2021
OBJECTIVE: To determine the treatment effect of psychodynamic therapy for adolescents in comparison to normative developmental progression in two groups without treatment: healthy adolescents and adolescents with juvenile diabetes. RESEARCH DESIGN AND METHODS: In a 3-wave longitudinal study, n = 531 adolescents (n = 303 treated adolescents, n = 119 healthy, n = 109 with diabetes) and their parents filled out psychopathology questionnaires (Youth Self-Report [YSR] and Child Behaviour Checklist [CBCL]). Growth curve modeling (GCM) was used to examine within-person change in psychopathology while controlling for stable between-person differences. RESULTS: GCM analyses revealed significant with…
Physical fitness development in relation to changes in body composition and physical activity in adolescence
2020
The decline in adolescents’ physical fitness (PF) in recent decades has raised concerns about current population’s possible future challenges with health and physical functional capacity. This study explored the associations between body composition, physical activity, maturation, and PF development in adolescents. Furthermore, PF development of adolescents with low initial PF was assessed. A 2‐year observational study was conducted between spring 2013 and 2015. Nine comprehensive schools and their 10‐ to 13‐year‐old students were invited to participate in the study (1778), and a total of 971 students (54.6%) agreed. Cardiorespiratory fitness (20‐metre shuttle run), muscular fitness (push‐u…
