Design and Validation of the Brief Self Online Scale (SO-8) in Early Adolescence: An Exploratory Study

2020

For the Z-Generation, the Internet has become a very important experimentation laboratory for the discovery and validation of their identity. Despite the importance of the process of building the self in the adolescent, there are hardly any validated instruments that measure the self online. The aim of this research was to design and validate the Brief Self Online Scale (SO-8). A total of 843 students (384 boys, 45.6%), with an age range of 10 to 14 years participated. Confirmatory factor analysis (CFA) confirmed the hypothesized model of two correlated factors (Online Self-Perception and Online Idealized Projection), previously obtained through exploratory factor analysis (EFA). The relia…

Social comparisons at work as related to a cooperative social climate and to individual differences in social comparison orientation

2005

This study examined the frequency of social comparisons in a work setting, and the feelings that these comparisons evoked. These processes were related to individual differences in social comparison orientation, and to the perception of a cooperative social climate at work. The participants were 216 physicians from various health centers in the Community of Valencia in Spain. In general, upward comparisons occurred more often, and elicited more positive and less negative affect than downward comparisons. Those high in social comparison orientation reported relatively more upward as well as downward comparisons, more positive affect after downward comparisons, and more negative affect after …

More hours, more jobs? The employment effects of longer working hours

2014

Increases in standard hours of work have been a contentious policy issue in Germany. Whilst this might directly lead to a substitution of workers by hours, there may also be a positive employment effect due to reduced costs. Moreover, the response of firms may differ between firms that offer overtime and those that do not. For a panel of German plants (2001–2006) drawn from the IAB Establishment Panel, we are the first to analyse the effect of increased standard hours on employment. Using difference-in-difference methods we find that, consistent with theory, overtime plants showed a significant positive employment response, whilst for standard-time plants there is no difference between plan…

Childcare and parental work schedules: a comparison of childcare arrangements among Finnish, British and Dutch dual-earner families

2015

This study examined the association between parental work schedules and non-parental childcare arrangements among dual-earner families in Finland, the Netherlands and the UK. Data from the ‘Families 24/7’ web-survey were used, including 937 parents with children aged 0-12 years. Results showed a negative association between non-standard work and formal childcare across all countries. A similar association was found for using a combination of formal and informal childcare, whereas solely using informal childcare was not associated with work characteristics. Country differences showed that, compared with Finland, the probability of using formal childcare was lower in the Netherlands, whereas …

Parental and Familial Factors Influencing Physical Activity Levels in Early Adolescence: A Prospective Study

2020

Parental/familial factors are important determinants of the physical activity level (PAL) in children and adolescents, but studies rarely prospectively evaluate their relationships. This study aimed to evaluate the changes in physical activity levels among adolescents from Bosnia and Herzegovina over a two-year period and to determine parental/familial predictors of PAL in early adolescence. A total of 651 participants (50.3% females) were tested at baseline (beginning of high school education

Sex-specific transgenerational effects of early developmental conditions in a passerine.

2007

Most studies dealing with the trade-off between offspring number and quality have overlooked the long-term consequences for the progeny. High investment in offspring number usually results in an increased competition among nest mates. The deterioration of the early developmental conditions, due to this increased competition, can impair individual quality over the long term, and subsequently affect survival and lifetime fecundity. Moreover, the consequences of the allocation rule to offspring number vs. quality can extend across generations and give raise to grandparental effects. These transgenerational trade-offs have been explored rarely. In the present study, we manipulated the breeding …

Contribution of the Temporal Dominance of Sensations (TDS) method to the sensory description of subtle differences in partially dealcoholized red win…

2007

ln this study, effect of partial alcohol reductio.n on the sensory modification of red wines was investigated. Preliminary triangle tests indicated the existencèof very slight differences between the dealcoholized wines of the study. Therefore, adapted descriptive methodologies had ta be used. ln addition to a comparative sensory profile, the Temporal Dominance of Sensations (TDS) method was chosen. Both types of profiles will be linked ta consumer preferences. A Merlat and a Syrah wine were partially dealcoholized using reverse osmosis technique to span a range of four different alcohol contents (14 % to 10 %) by grape variety. ln a first step, the four wines of each variety were compared …

Plasma omega 3 polyunsaturated fatty acids and macular pigment optical density in subjects at high risk for age-related macular degeneration: the Lim…

2016

This is an abstract that was submitted for the 2016 ARVO Annual Meeting, held in Seattle, Wash., May 1-5, 2016.; Purpose: In numerous epidemiological studies, omega 3 polyunsaturated fatty acids (PUFAs) have been associated with a decreased risk of age-related macular degeneration (AMD). Beyond their structural, functional and neuroprotective roles, omega 3 PUFAs may favor the retinal accumulation of lutein and zeaxanthin and thus increase macular pigment optical density (MPOD). We examined the associations of MPOD with plasma omega 3 PUFAs in subjects with at least one parent affected by neovascular AMD. Methods: The Limpia study is a double-blind, placebo controlled, prospective randomize…
