Self and Nature: Parental Socialization, Self-Esteem, and Environmental Values in Spanish Adolescents
2020
Emergent research seriously questions the use of parental strictness as the best parenting strategy in all cultural contexts. Moreover, previous research on environmental socialization offers inconsistent findings about which specific parenting practices would be the most appropriate for environmental socialization. The present paper aims to examine parents&rsquo
Use of the Perceived Physical Competence Scale with Adolescents with Disabilities
1995
The construct validity and reliability of the 1987 Perceived Physical Competence Scale of Lintunen were examined to assess the applicability of the instrument for use with adolescents with disabilities. Subjects were 51 girls and 34 boys ( M age = 15.1 yr.) from several schools in central Finland. Principal component factor analysis with varimax rotation yielded the same two factors for adolescents with disabilities as reported for nondisabled adolescents in the related literature. Cronbach alphas for the two factors were .89 and .56. It was concluded that the scale is an appropriate measure for adolescents with disabilities. Statistical analysis indicated no gender differences for adolesc…
Bolton's intermaxillary tooth size ratios among Iranian schoolchildren.
2010
Objectives: The aims of the present study were to determine anterior and total tooth-width ratios in a representative Iranian sample in Tabriz city and compare them with the Bolton standards. Study design: A total of 54 Iranian schoolchildren (12-14 years old) in Tabriz were examined. Alginate impressions were taken for subjects and poured by the dental stone. The mesiodistal widths of the teeth were measured using a digital caliper. The overall and anterior Bolton's intermaxillary tooth size ratios for each model pair was calculated. Results: There were no significant differences (p > 0.05) between the right and left sides of the dental arch and a symmetry in size exists. There were no sig…
Mesiodistal sizes and intermaxillary tooth-size ratios of two populations; Spanish and Peruvian. A comparative study.
2010
Introduction: Adequate tooth-size ratios are required to ensure the satisfactory outcome of orthodontic treatment. Consequently, various methods of measuring tooth-size ratios have been developed being the Bolton ratio the most commonly accepted, known and used one. This ratio depending directly on mesiodistal tooth size has been associated with different ethnic backgrounds. Some authors suggest the need for specific standards for every population. Objectives: The objectives of our study were; to measure and to compare mesiodistal tooth sizes and the Anterior and Overall Bolton ratios in two different populations, one Peruvian and the other Spanish with the same digital method. Material and…
Rectal pH in children
1989
In an attempt to establish normal values for rectal pH in children, we have measured pH in 100 paediatric patients. Measurement of rectal pH was performed in 25 infants and 75 children (27 girls and 73 boys) using a monocrystalline antimony electrode. Rectal pH was 9.6 +/- 0.9 (mean +/- SD, range 7.2 to 12.1) and was independent of sex, age and nutrition. This wide range of rectal pH values offers a possible explanation for the widely scattered bioavailability of drugs administered by the rectal route. Mean rectal pH was considerably higher than that reported for adults; this unexpected alkalinity should be taken into account, when drug formulations are considered for rectal administration …
Echocardiographic reference ranges for normal cardiac Doppler data: results from the NORRE Study
2015
International audience; AIMS: Reference values for Doppler parameters according to age and gender are recommended for the assessment of heart physiology, specifically for left ventricular (LV) diastolic function. In this study, we report normal reference ranges for Doppler parameters obtained in a large group of healthy volunteers. Echocardiographic data were acquired using state-of-the-art cardiac ultrasound equipment following Doppler acquisition and measurement protocols approved by the European Association of Cardiovascular Imaging. METHODS AND RESULTS: A total of 449 (mean age: 45.8 ± 13.7 years) healthy volunteers (198 men and 251 women) were enrolled at the collaborating institutions…
Can Self-Enhancement Values Predict Retirement Behavior? An Analysis Combining Survey and Register Data From Norway
2015
This analysis investigates to what extent the self-enhancement values in the Schwartz taxonomy—achievement, power, and hedonism—can predict retirement behavior. Self-enhancement values were measured using the Norwegian Life Course, Generations and Gender Study beginning in 2007. Register data were merged with the survey data to identify those collecting a pension by the end of 2010; these persons were defined as being retired. Statistical analysis was performed using discrete time proportional odds (logistic regression) duration models for each birthday. The results show that two self-enhancement values, achievement and hedonism, discourage disability retirement but do not affect nondisabi…
Estimation of Short Temporal Intervals in Alzheimer's Disease
2000
This study investigated the estimation of short temporal intervals in Alzheimer's disease (AD). Eight patients with dementia of the Alzheimer type, and eight age-matched controls were evaluated in a time-estimation task. The task consisted in the production of three short empty intervals (5, 10, and 25 s). Results indicated that AD patients show deficits both in the accuracy and precision of time judgments: in the three intervals evaluated, the magnitude of absolute error and the variability in time judgments were significantly greater in AD patients than healthy respondents (p < .01). These findings are discussed taking into account the contribution of attentional processes during the perf…
Shifts in Key Time Points and Strategies for a Multisegment Motor Task in Healthy Aging Subjects
2018
International audience; In this study, we compared key temporal points in the whole body pointing movement of healthy aging and young subjects. During this movement, subject leans forward from a standing position to reach a target. As it involves forward inclination of the trunk, the movement creates a risk for falling. We examined two strategic time points during the task-first, the crossover point where the velocity of the center of mass (CoM) in the vertical dimension outstripped the velocity in the anteroposterior dimension and secondly, the time to peak of the CoM velocity profile. Transitions to stabilizing postures occur at these time points. They both occurred earlier in aging subje…
Muscle strength and mobility as predictors of survival in 75-84-year-old people.
1995
The purpose of the study was to examine the association of physical capacity, as determined on the basis of self-report and physical measurements, with survival in three groups of elderly people aged 75, 80 and 75-84 years. The main aspects of physical capacity were mobility, walking speed, hand grip strength and knee extension strength. Although 1142 persons participated in mobility interview, of whom 466 also took part in the walking speed test, and 463 in the strength tests. The follow-up periods ranged from 48 to 58 months. Risk of death was significantly related to difficulties in indoor mobility among the 75-84-year-olds (odds ratio = 1.99, 95% confidence interval = 1.27-3.13) and 75-…
