Enhanced Lipid Peroxidation and Platelet Activation in the Early Phase of Type 1 Diabetes Mellitus
2003
Background— To investigate early events possibly related to the development of diabetic angiopathy, we examined whether 8-iso-prostaglandin F 2α (8-iso-PGF 2α ) formation, a marker of in vivo oxidant stress, is altered in different stages of type 1 diabetes (T1DM) and whether it correlates with the rate of thromboxane (TX) A 2 biosynthesis, a marker of in vivo platelet activation. We also investigated the relationship between inflammatory markers and F 2 -isoprostane formation in this setting. Methods and Results— A cross-sectional study was performed in 23 insulin-treated patients aged <18 years with new-onset T1DM (≤6 weeks, group A), matched for age and gender with 23 patients with s…
Financial literacy among Finnish adolescents in PISA 2018 : the role of financial learning and dispositional factors
2021
The aim or the present study was to examine the relative importance of financial education in school and families and dispositional factors (competitiveness, work mastery, meta-cognition) in predicting financial literacy among Finnish adolescents. The data on the 4328 Finnish 15-year-olds was drawn from the PISA 2018 assessment. Financial literacy was measured by tests, and financial education and dispositional factors were assessed by adolescent questionnaires.

Investigation and control of a Norovirus outbreak of probable waterborne transmission through a municipal groundwater system

During March 2011 an outbreak of gastroenteritis occurred in Santo Stefano di Quisquina, Agrigento, Sicily, Italy. Within two weeks 156 cases were identified among the 4,965 people living in the municipality. An epidemiological investigation was conducted to characterize the outbreak and target the control measures. A case was defined as a person developing diarrhea or vomiting during February 27–March 13, 2011. Stool specimens were collected from 12 cases. Norovirus (NoV) genotype GII.4 variant New Orleans 2009 was identified in stool samples from 11 of 12 cases tested (91.7%).

Adolescents’ and mothers’ temperament types and their roles in early adolescents’ socioemotional functioning
2018
The present study examined adolescents’ and mothers’ temperament types and their roles in the socioemotional functioning of early adolescents. A total of 869 sixth-grade students and 668 mothers participated in the study. The students rated their temperament and socioemotional functioning and the mothers rated their own temperament. Latent profile analyses identified four temperament types among the adolescents (resilient, reserved, average, and mixed) and three types among the mothers (resilient, average, and mixed). The results showed that the adolescents with resilient or reserved temperaments reported significantly fewer conduct problems and emotional symptoms, less hyperactivity, and …
Longitudinal and situational associations between math anxiety and performance among early adolescents
2022
Studies have found math anxiety and achievement to be related from the beginning of formal schooling, but the knowledge regarding the direction of the relationship is vague. The purpose of the present study was to study this relationship. We investigated math anxiety from two points of view: trait and state anxiety. In the first substudy, we investigated the longitudinal relationship between math anxiety and performance from sixth to seventh grade (n = 848) with cross-lagged modeling. In the second substudy, we investigated the situational relationship of anxiety and performance by giving the participants (n = 149) challenging and nonchallenging math tasks adapted to their skill level, and …
Early marriage and cultural constructions of adulthood in two slums in Dar es Salaam.
2018
This study examines under-18 marriage in urban Tanzania from an ethnographic perspective. Due to poverty and high unemployment, some girls aspire to early marriage. Two pathways to early marriage are identified: first, poverty and gendered economic disparities motivate girls to begin transactional sexual activity at an early age, leading parents to favour early marriage as a risk-reduction measure. Second, educational opportunities are often closed off to girls before marriage, as a result of which early marriage becomes the only culturally approved pathway that allows girls to present themselves to others as a self-sufficient agent. These pathways are reinforced by cultural and religious c…

Asociación entre clima motivacional, ajuste escolar y funcionalidad familiar en adolescentes
2019
The present study seeks to define and contrast an explanatory model of motivational climate, school adjustment and family functioning, and to analyse the existing associations between the aforementioned variables through structural equation analysis. The sample includes 2,134 adolescents aged 12 to 18 years from the province of Granada. Motivational climate (PMCSQ-2), school adjustment (EBAE-10) and family functioning (APGAR) are analysed. A descriptive cross-sectional design is used and the program AMOS 23.0 is employed to construct the multi-group structural equation model. The model showed appropriate fit (χ2 = 241.34; df = 17; p < .001; CFI = .953; NFI = .950; IFI = .953; RMSEA = .079).…
