Immediate Effects of Vibration Transmitted to the Hand
1981
Summary Three different research projects have been accomplished on the problems: biomechanical behaviour of the hand-arm-system; subjective sensation; physiological changes. Some of the main results were:—the wrist and—with smaller amplifications—the elbow show resonances at low vibration frequencies (10–20 Hz);—with constant acceleration subjective perception decreases with increasing frequency;—application of static grip force—without vibration—causes significant reduction of the skin temperature, which under vibration stress remains at the same lowered level.
Gender Behavioral Issues and Entrepreneurship
2017
Women, despite the fact that they make up around 50% of the world’s population, own and manage significantly fewer businesses than men worldwide. Previous empirical research indicates that the gender gap in entrepreneurial propensity mainly comes from subjective perceptions as self-confidence in one’s own skills and fear of failure, and from women’s lower exposure to other entrepreneurs. In this chapter we present laboratory economic experiments that study, under controlled conditions, subjective perceptions of women and men that seem to affect entrepreneurial propensity. The results of the reviewed experiments indicate that correcting factors such as self-confidence is possible (due to its…
Sensibility and taste alterations after impacted lower third molar extractions. A prospective cohort study
2012
Objectives: To determine the incidence, severity and duration of lingual tactile and gustatory function impairments after lower third molar removal. Study Design: Prospective cohort study with intra-subject measures of 16 patients undergoing lower third molar extractions. Sensibility and gustatory functions were evaluated in each subject preoperatively, one week and one month after the extraction, using Semmes-Weinstein monofilaments and 5 different concentrations of NaCl, respectively. Additionally, all patients filled a questionnaire to assess subjective perceptions. Results: Although patients did not perceive any sensibility impairments, a statistically significant decrease was detected …
The Transition from Middle School to High School: The Mediating Role of Perceived Peer Support in the Relationship between Family Functioning and Sch…
2018
The study focused on the transition from middle school to high school and aimed to verify the mediating role that perceived peer support may play in the relationship between family functioning in middle school and school satisfaction in high school. In middle school (Wave 1), participants were 208 adolescents (106 boys and 102 girls) aged 12–13 years (M = 12.56; SD = .61), attending the last classes of two middle public schools located in Italy. One year later (Wave 2), 155 adolescents (76 boys and 79 girls) participated again in the study when they attended the first classes of high school (M = 13.91; SD = .75). Participants completed the Italian Version of Family Assessment Device and the…
Les deux faces – objective/subjective – de la mobilité sociale
2006
06062; National audience; How does objective social mobility, traditionally measured with tables of mobility drawn up by sociologists, relate to feelings about mobility, i.e., how individuals perceive, explain and appraise their social trajectory? Using a question from a survey (Insee's Formation, qualification professionnelle), subjective mobility was statistically evaluated so as to bring the two approaches to mobility together and measure the (considerable) frequency of deviations. Subjective mobility was then analyzed qualitatively on the basis of interviews conducted with respondents in the same survey. This helps us account for deviations and identify the bundle of parameters that peo…
Students' school‐level symptoms mediate the relationship between a school's observed moisture problems and students’ subjective perceptions of indoor…
2020
Moisture damage can influence the subjective assessment of indoor air quality (subjective IAQ) in various ways. We studied whether the frequency of symptoms reported across students at school level mediates the relationship between observed mold and dampness in a school building and students' subjective IAQ. To answer this research question, we tested a multilevel path model. The analyzed data were created by merging two nationwide data sets: (a) survey data from students, including information on subjective IAQ (N = 24,786 students); (b) data from schools, including information on mold and dampness in a school building (N = 222). After the background variables were adjusted, schools' obser…
Wiki-mediated Collaborative Writing in Teacher Education - Assessing Three Years of Experiences and Influencing Factors
2014
Wikis have been reported as tools that promote collaborative writing in educational settings. Examples of wikis in teacher education are group projects, glossary creation, teacher evaluation, and document review. However, in spite of studies that report on successful stories, the claim that wikis support collaborative writing has not yet been firmly confirmed. Most studies are limited to participantsâ subjective perceptions, and do not take into account influencing factors, or the relationships between wikis and the learning environment. In this paper, studentsâ collaborative writing activities over a period of three years are investigated using a taxonomy of action categories and the w…
On the relations between audio features and room acoustic parameters of auralizations
2013
The usual parameters in room acoustics are used to quantify the acoustic characteristics of rooms and their relation to the subjective perception of transmitted signals. Audio features (calculated with MIRToolbox) have been designed to study the relationships between the characteristics of musical audio files and their subjective perception. Both musical characteristics and acoustic parameters are oriented towards acoustic perception. By using auralizations with calibrated models of auditoriums and tools from the MIRtoolbox it is possible to jointly work with the calculation of audio features and room parameters. In this work, the statistical correlations between C80, STI, D50, EDT, RT and …
Subjective Perception of Time: Research Applied on Dynamic Psychology
2017
The time marked by the clock hands, the so-called “objective time,” is deeply different from the one perceived by the individual. Starting from this hypothesis, directly connected to the subjective...
