Lab And/Or Field? Measuring Personality Processes and Their Social Consequences

2015

How can researchers study personality processes and their social consequences? In our methodology overview, we first introduce ambulatory assessment methods, which repeatedly measure experiences, physiology and behaviour in people's daily lives based on real–time assessments of self–reports, physiological activity and behavioural observations. Then, we describe methods suitable for assessing personality processes in laboratory settings: self–reports on interpersonal perception, physiological measurements and behavioural observation. We discuss the combination of field and laboratory assessment methods based on their respective strengths and limitations and then highlight ethical issues sur…

Stock de semences versus relevé de flore : comment mesurer les évolutions de la flore adventice liées à des modifications de systèmes de culture ?

2019

Le suivi des changements de la composition adventice est une préoccupation majeure lors de la mise en place de nouveaux systèmes de culture. Il se pose toutefois des questions sur la méthodologie à mettre en place pour ce type de travail. L’étude du stock de semences qui représente en théorie la flore potentielle, semble s’imposer comme la façon la plus évidente de caractériser les communautés de mauvaises herbes. Toutefois cette méthode est lourde à mettre en place et nécessite un nombre d’échantillons important. La flore adventice d’une centaine de parcelles conduites en semis direct sous couvert a été étudiée au travers de deux méthodes : un relevé de flore réalisé au printemps et un éch…

Success in reaching affect self-regulation goals through everyday music listening

2023

While music listening on mobile phones can serve many affect-regulatory goals, success in reaching these goals is yet to be empirically assessed. This study aimed to determine how frequently listeners successfully reach their affect-regulatory goals, and the predictors of this success. Data were collected using the experience sampling app MuPsych, from 293 Finnish participants. Goals were successfully reached in less than half of cases, with adults more successful than adolescents. Success was determined largely within contexts, and strongly predicted by an initial low-valenced emotional state of the listener, suggesting that music listening is particularly useful for those in negative stat…

Indoor Air Quality including Respiratory Viruses

2021

The detection of SARS-CoV-2 in indoor environments is a cause of increasing concern. In this study, three sampling methodologies have been used in order to collect SARS-CoV-2 and 17 other respiratory viruses in indoor air, combined with a new analytical process to analyze respiratory viruses. Different areas of an ophthalmological hospital were investigated for the presence of these airborne viruses. Moreover, indoor air quality (IAQ) parameters (carbon dioxide, CO2; carbon monoxide, CO; nitrogen dioxide, NO2; volatile organic compounds, VOCs; formaldehyde, HCHO; and particulate matter, PM) have been examined to study the relationship between IAQ and airborne viruses. All indoor air and sur…

Self-Control Dynamics in Daily Life: The Importance of Variability Between Self-Regulatory Strategies and Strategy Differentiation

2021

Research on self-control has increasingly acknowledged the importance of self-regulatory strategies, with strategies in earlier stages of the developing tempting impulse thought to be more effective than strategies in later stages. However, recent research on emotion regulation has moved away from assuming that some strategies are per se and across situations more adaptive than others. Instead, strategy use that is variable to fit situational demands is considered more adaptive. In the present research, we transfer this dynamic process perspective to self-regulatory strategies in the context of persistence conflicts. We investigated eight indicators of strategy use (i.e., strategy intensit…

Assessing the performance of a large-scale irrigation system by estimations of actual evapotranspiration obtained by Landsat satellite images resampl…

2019

Abstract Remote sensing techniques allow monitoring the Earth surface and acquiring worthwhile information that can be used efficiently in agro-hydrological systems. Satellite images associated to computational models represent reliable resources to estimate actual evapotranspiration fluxes, ETa, based on surface energy balance. The knowledge of ETa and its spatial distribution is crucial for a broad range of applications at different scales, from fields to large irrigation districts. In single plots and/or in irrigation districts, linking water volumes delivered to the plots with the estimations of remote sensed ETa can have a great potential to develop new cost-effective indicators of irr…

Finnish Students’ Engagement in Science Lessons

2015

The decreasing number of students who are engaged in science learning has been recognised as a problem. The pre-conditions of engagement and actual engagement were examined using a novel research method to obtain detailed information on Finnish students’ engagement in different situations and to gain a better understanding of this phenomenon. The study’s participants consisted of 68 students (31 girls, 37 boys) from 9th grade and 67 students (46 girls, 21 boys) from 1st grade in upper secondary school. The research aimed to answer the following question: How does Finnish students’ engagement occur in exact and life science lessons? Participants received smartphones equipped with a smartphon…

From being alone to being the only one: Neuroticism is associated with an egocentric shift in an alone context

2019

Objective This research presents evidence for an egocentric shift occurring among individuals high in Neuroticism by the mere thought-and actual state-of being alone. Method Four experiments and one experience sampling study (N = 719). In the experiments, Neuroticism was measured, and participants were randomly primed to adopt either an alone or a "with others" social context mind-set. The experiments measured different expressions of egocentrism. Study 1 measured perspective-taking, Study 2a was focused on social value orientation, Study 2b measured money allocation in a dictator game, and Study 3 measured self-reported and behavioral interpersonal trust. Trust was also the focus of Study …

Variation in situation-specific engagement among lower secondary school students

2018

The majority of previous research has examined school engagement as an overall student characteristic. The present study contributes to the field by examining variation in students' situation-specific engagement from one lesson to another and by investigating situational determinants of such variation. An intensive one-week lesson-to-lesson data collection was conducted in four lower secondary school classrooms. Students rated their situation-specific engagement at the end of each lesson with a mobile-based InSitu instrument. Data comprising a total of 57 students and 1328 ratings were analyzed with two-level hierarchical multivariate model (between students, and within students between les…
