Moderating cultural effects in a higher e-education context? Supervisor's tone of voice in recorded audio feedback
2017
Providing feedback to learners on their writing assignments is one of the most important and time-consuming tasks that a supervisor performs. In e-Education environments, especially in the case of distance learning, giving feedback becomes more challenging because there are often no opportunities for face-to-face interaction. Typically, a supervisor provides comments to learners in written form via email; however, the use of recorded audio feedback (RAF) in e-Education environments has become a viable alternative. This work in progress reports on learners’ perceptions of RAF in a multi-cultural higher eEducation context. Our observations indicate that learners tend to have positive feelings…
Global Perspective on Marital Satisfaction
2020
Across the world, millions of couples get married each year. One of the strongest predictors of whether partners will remain in their relationship is their reported satisfaction. Marital satisfaction is commonly found to be a key predictor of both individual and relational well-being. Despite its importance in predicting relationship longevity, there are relatively few empirical research studies examining predictors of marital satisfaction outside of a Western context. To address this gap in the literature and complete the existing knowledge about global predictors of marital satisfaction, we used an open-access database of self-reported assessments of self-reported marital satisfaction wit…
Measuring the Economic, Environmental, and Social Sustainability of Short Food Supply Chains
2019
The production and distribution of food are among the hot topics debated in the context of sustainable development. Short food supply chains (SFSCs) are now widely believed to be more sustainable in comparison to mass food delivery systems. To date, very little quantitative evidence exists on the impacts of various types of food supply chains. Using a cross-sectional quantitative approach, this study assesses the sustainability of distribution channels in short and long food supply chains based on 208 food producers across seven countries: France, Hungary, Italy, Norway, Poland, the United Kingdom, and Vietnam. Ten distribution channel types are used in this study. To provide a comprehensiv…

Kouluvalintapolitiikka perusopetuksessa: suomalaiskaupunkien koulumarkkinat kansainvälisessä valossa
2006
Tutkimuksessa tarkastellaan kouluvalintapolitiikan käyttöä lasten sijoittamisessa oppivelvollisuuskouluihin. Kyse on ylikansallisesta toimintapolitiikasta, jonka mukaan vanhemmat voivat hakea lapselle koulupaikkaa haluamaansa kouluun ja koulut voivat (osittain) valita oppilaansa. Kouluvalintapolitiikkaa on toteutettu Suomen yhtenäiskoulujärjestelmässä 1990-luvun puolivälistä alkaen. Kouluvalintapolitiikan tapahtumapaikka käsitteellistetään koulumarkkinoiksi. Käsitteen koulumarkkinat päällekkäisiä merkityksiä eritellään ideologiseksi malliksi (koulumarkkinat, hallinnolliseksi malliksi (kvasimarkkinat), alueelliseksi malliksi (paikalliset koulumarkkinat ja empiiriseksi tutkimuskohteeksi (elet…
Substituent effects of nitro group in cyclic compounds
2020
AbstractNumerous studies on nitro group properties are associated with its high electron-withdrawing ability, by means of both resonance and inductive effect. The substituent effect of the nitro group may be well described using either traditional substituent constants or characteristics based on quantum chemistry, i.e., cSAR, SESE, and pEDA/sEDA models. Interestingly, the cSAR descriptor allows to describe the electron-attracting properties of the nitro group regardless of the position and the type of system. Analysis of classical and reverse substituent effects of the nitro group in various systems indicates strong pi-electron interactions with electron-donating substituents due to the re…
150 years of rowing faster: what are the sources of more and more speed?
2015
Rowing has a 150 yr+ competitive history. Examining results from historic races like Oxford-Cambridge (established 1829) and the world championships (established 1893) reveals a linear increase in boat speed by 2-3% per decade. Boat velocity increases if propulsive power is increased and/or power losses are reduced. Over time, the propulsive power capacity of elite rowers has increased. Part of this increase is a result of recruiting athletes from a population that has become taller (1-3 cm per decade) and heavier. Modern world class rowers are typically 190-200 cm tall and weigh 90-100 kg. However, physical capacity does not scale directly with body dimensions but conforms instead to biolo…
Cannabis-associated symptom profiles in patients with first episode psychosis and population controls
2019
AbstractObjectiveThe evidence is mixed on whether cannabis use is associated with a particular symptomatology in first episode psychosis (FEP) patients.The authors set out to investigate a) patterns of association between cannabis use and transdiagnostic symptom dimensions; b) whether the extent of use of cannabis contributes to the variation in clinical and subclinical symptom profiles.MethodThe authors analysed data from 901 patients and 1235 controls recruited across six countries, as part of the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. Item response modelling was used to estimate two bifactor models, which included genera…
Bayesian reanalysis of a quantitative trait locus accounting for multiple environments by scaling in broilers1
2006
A Bayesian method was developed to handle QTL analyses of multiple experimental data of outbred populations with heterogeneity of variance between sexes for all random effects. The method employed a scaled reduced animal model with random polygenic and QTL allelic effects. A parsimonious model specification was applied by choosing assumptions regarding the covariance structure to limit the number of parameters to estimate. Markov chain Monte Carlo algorithms were applied to obtain marginal posterior densities. Simulation demonstrated that joint analysis of multiple environments is more powerful than separate single trait analyses of each environment. Measurements on broiler BW obtained from…
Respuesta cardiovascular al estrés en pacientes con epilepsia farmacorresistente: datos preliminares
2021
El estrés es un factor de riesgo para las enfermedades cardiovasculares en la población general. La epilepsia se ha considerado un modelo adecuado de estrés crónico, con mayor incidencia de mortalidad cardiovascular que la población general. Este estudio proporciona datos preliminares sobre la respuesta cardiovascular ante un estresor cognitivo y una evaluación neuropsicológica en pacientes con epilepsia, explorando las relaciones entre la respuesta cardiovascular y el rendimiento cognitivo dependiendo del hemisferio responsable de la epilepsia. Treinta y cinco pacientes con epilepsia farmacorresistente, 17 con el área epileptógena(AE) en el hemisferio izquierdo (LH) y 18 con AE en el hemis…
