Vocational education approach: New TEL settings—new prospects for teachers' instructional activities?

2013

This study focuses on vocational education teachers’ instructional activities in a new technology-enhanced learning (TEL) setting. A content analysis is applied to investigate teachers’ and students’ interactions in a 3D game context. The findings illustrate that when teachers’ and students’ interactions are mediated by a game, teachers seem to apply different discussion activities to empower vocational learning than they do in traditional classroom settings. Additionally, the present study shows that teachers spontaneously develop new ways of supporting vocational learning processes. In more detail, two main types of instructional activities were identified: a “knowledge-providing” approac…

An N-terminal deletion variant of HCN1 in the epileptic WAG/Rij strain modulates HCN current densities.

2015

Rats of the Wistar Albino Glaxo/Rij (WAG/Rij) strain show symptoms resembling human absence epilepsy. Thalamocortical neurons of WAG/Rij rats are characterized by an increased HCN1 expression, a negative shift in Ih activation curve, and an altered responsiveness of Ih to cAMP. We cloned HCN1 channels from rat thalamic cDNA libraries of the WAG/Rij strain and found an N-terminal deletion of 37 amino acids. In addition, WAG-HCN1 has a stretch of six amino acids, directly following the deletion, where the wild-type sequence (GNSVCF) is changed to a polyserine motif. These alterations were found solely in thalamus mRNA but not in genomic DNA. The truncated WAG-HCN1 was detected late postnatal …

Plant Productivity Dispersion and the College Premium: Evidence from the United States 1977-1997

2015

For the United States in 1987-2014, I document at business cycle frequencies that the high-skill workers’ employer size wage premium is high (low) in times of low (high) unemployment relative to that of the low-skill workers. Specifically, the differential employer size wage premium between high-skill and low-skill workers has an unconditional correlation of -0.4 with the unemployment rate, and varies by about 6 percent over the business cycle. The skill premium itself does not exhibit a clear business cycle pattern over the sample period.

Birth weight, cardiometabolic risk factors and effect modification of physical activity in children and adolescents: pooled data from 12 internationa…

2020

Abstract Objectives Low and high birth weight is associated with higher levels of cardiometabolic risk factors and adiposity in children and adolescents, and increases the risk of cardiovascular diseases, obesity, and early mortality later in life. Moderate-to-vigorous physical activity (MVPA) is associated with lower cardiometabolic risk factors and may mitigate the detrimental consequences of high or low birth weight. Thus, we examined whether MVPA modified the associations between birth weight and cardiometabolic risk factors in children and adolescents. Methods We used pooled individual data from 12 cohort- or cross-sectional studies including 9,100 children and adolescents. Birth weigh…

Religious social engagement and valuation of life in Portuguese centenarians

2017

In very advanced age, successful aging becomes more and more difficult, for instance because age-related losses challenge the possibility to remaining socially engaged. This study analyzes the activity engagement patterns of Portuguese centenarians and its relation with well-being. A sample of 89 centenarians (Mage= 101.1 years, SD=1.4, range: 100–105) from the PT100 Oporto Centenarian Study was considered. Results demonstrated that the majority of the centenarians performed religious activities (94.4%), with 80 individuals (89.9%) praying and 34 (38.2%) going to the church. Regression analyses indicated that religious social engagement was related to Valuation of Life, even when the contri…

Business choices, risk management and distortions in the wine market in the European Union

2020

The objective of this work is to analyze the management of technical and economic risks in agri-food production. It is well established that any business activity is characterized by risks that, if not managed efficiently and effectively, can cause a company’s downward spiral. In this context, the management of a winery requires the adoption of company policies aimed at reducing risk. This study highlights the fact that the wine insurance market is characterized by information asymmetry and adverse selection that contribute to the creation of ‘distorted markets’. The results of the empirical analysis show the collapse of subsidized insurance contracts in viticulture leading to a decrease in…

SCHOOL PSYCHOLOGISTS’ ETHICAL STRAIN AND RUMINATION: INDIVIDUAL PROFILES AND THEIR ASSOCIATIONS WITH WEEKLY WELL-BEING

2016

We investigated school psychologists’ experiences of ethical strain (the frequency of ethical dilemmas at work and the stress caused by these dilemmas) and dilemma-related rumination outside working hours. Individual latent profiles were estimated at the study baseline based on these three dimensions. The psychologists’ weekly well-being (vigor, exhaustion, and sleep quality) was compared against their profile during the following three working weeks. The sample included 133 school psychologists, among whom four groups were identified: Low ruminators (39%), an Intermediate group (39%), High ruminators (20%), and Atypical outliers (2%). High ruminators fared least well in terms of weekly wel…

2021

Background: Normal aging is associated with working memory decline. A decrease in working memory performance is associated with age-related changes in functional activation patterns in the dorsolateral prefrontal cortex (DLPFC). Cognitive training can improve cognitive performance in healthy older adults. We implemented a cognitive training study to assess determinants of generalization of training gains to untrained tasks, a key indicator for the effectiveness of cognitive training. We aimed to investigate the association of resting-state functional connectivity (FC) of DLPFC with working memory performance improvement and cognitive gains after the training.Method: A sample of 60 healthy o…

Working memory (WM) performance declines with age. However, several studies have shown that WM training may lead to performance increases not only in the trained task, but also in untrained cognitive transfer tasks. It has been suggested that transfer effects occur if training task and transfer task share specific processing components that are supposedly processed in the same brain areas. In the current study, we investigated whether single-task WM training and training-related alterations in neural activity might support performance in a dual-task setting, thus assessing transfer effects to higher-order control processes in the context of dual-task coordination. A sample of older adults (…
