Self-perceptions of competence in Brazilian, Canadian, Chinese and Italian children: Relations with social and school adjustment
2004
The purpose of the present study was to examine relations between self-perceptions of competence and social, behavioural, and school adjustment in Brazilian, Canadian, Chinese, and Italian children. Self-perception data were collected through children’s self-reports. Information about social behaviours, peer acceptance, and school achievement was obtained from peer assessments and teacher ratings. Multi-group analyses revealed similar patterns of relations between self-perceptions in scholastic and general self-worth domains and social and school performance in the four samples. However, the relations between self-perceptions of social competence and shyness and academic achievement were d…
Inhibition of DNA synthesis in chick embryo retinas, in vitro, by a factor from fetal bovine serum
1989
Fetal bovine serum inhibited deoxyribonucleic acid (DNA) synthesis in chick embryo retina explants. The inhibitory activity was precipitated from fetal bovine serum by 45% saturated ammonium sulfate and isolated by means of Sephadex G-100 and Bio-Gel P-60 columns as a peak with an apparent molecular weight of 7000 Da. DNA-inhibiting activity was heat- and acid-stable and was destroyed by dithiothreitol and alkaline treatment. The purified factor inhibited similarly both DNA synthesis and thymidine kinase activity; 50% inhibitory effect was found with 160 ng, 17 h after the addition into the incubation medium.
Trajectories of depressive mood in adolescents: Does parental work or parent-adolescent relationship matter? A follow-up study through junior high sc…
2007
The purpose of this follow-up study was to investigate stability and change in depressive mood and possible explanatory factors between ages 13 to 16. The sample consisted of 116 Finnish adolescents (50 boys and 66 girls) drawn from two junior high schools in Central Finland.The data were obtained by means of questionnaires which were completed by the same adolescents three times, in 1999 (mean age 13.0 years), in 2001 (mean age 14.7 years), and in 2002 (mean age 15.9 years). The semiparametric group-based mixture modeling revealed four developmentally different trajectories in depressive mood, two indicating stability and two showing change in the level of symptoms over time. The majority…
New Nonlocal Biological Effect: A Preliminary Research
2012
We report here our experimental findings of new nonlocal biological effect measured objectively and quantitatively under blind conditions. The method used includes the steps of providing two parts of quantum-entangled medium, applying one part to a biological system such as a human, contacting the other part with a desired substance such as a medication, and detecting change of a biological parameter with a detecting device. Using this method, we have found that after consumption by a test subject of one part of the quantum entangled water, the subject’s heart rate was non-locally increased under blind conditions by adding to the second part of the quantum-entangled water an over-the-counte…
We Have a Dream: A Call to All Men and Women of Science and Religion to Rise Up
2008
In the spirit of Thomas Jefferson, Abraham Lincoln and Martin Luther King, Jr., we call all men and women of Science and Religion to rise up in the pursuit of truth.
Linkages between causal ascriptions, emotion, and behavior
1997
Italian schoolboys between the ages of 9 and 10 participated in three experiments guided by attribution theory as conceptualised by Weiner (1985, 1986). In Experiment 1, following teacher-emotional feedback of anger or sympathy for failure, attributional inferences regarding low ability or lack of effort as the cause of that failure were rated. In Experiment 2, controllable and uncontrollable causes of a social transgression were given, and children rated the anticipated anger of the “victim” and their intention to withhold or reveal the cause. In Experiment 3, effects of perceived causality and related emotions of anger and sympathy (pity) with regard to helping behaviour were investigate…
The adult Prosocialness behavior scale: A reliability generalization meta-analysis
2022
The Adult Prosocialness Behavior Scale (APBS) is most often used to measure adult prosociality. We conducted a reliability generalization meta-analysis to compute the average APBS reliability and examine the heterogeneity among reliability estimations and the influence of moderator variables. An exhaustive search identified 74 articles that applied the APBS with 16 items assessed on a 5-point Likert-type scale. Of these, 58 had reliability coefficients with the current data, and 76 reliability estimates were provided. Random- and mixed-effects models were used. The average reliability coefficient was .903 for Cronbach’s alpha, .896 for McDonald’s omega, and .674 for test–retest. Moderator …
Dimensions of executive functioning: Evidence from children
2003
This study investigated dimensions of executive functioning in 8- to 13-year-old children. Three tasks from the Cambridge Neuropsychological Test Automated Battery (CANTAB), two tasks from the NEPSY battery and some additional executive function (EF) tests were administered to 108 children. In line with earlier work, modest correlations among EF measures were obtained (r < .4). Both exploratory and confirmatory factor analyses yielded three interrelated factors, which resembled those obtained by Miyake et al. (2000) and which were—with some reservations—labelled Working Memory (WM), Inhibition and Shifting. Age correlated with performance on most individual EF measures as well as Shifting a…
Extracerebral biopsies in neurodegenerative diseases of childhood
1999
Abstract Among the numerous neurodegenerative diseases in children few may allow morphological diagnosis by extracerebral biopsy. These encompass neurometabolic conditions, foremost lysosomal disorders, but also peroxisomal and mitochondrial diseases marked by disease- or group-specific organelles. Largely, these neurometabolic conditions can also be diagnosed by biochemical and increasingly by molecular genetic techniques. However, there are a few neurodegenerative diseases which do not allow either biochemical or molecular genetic diagnosis and, thus, rely on biopsy of extracerebral tissues, so-called ‘essential’ biopsies to achieve a diagnosis during the patient's life. Among these few d…
Up and Down States During Slow Oscillations in Slow-Wave Sleep and Different Levels of Anesthesia
2021
Slow oscillations are a pattern of synchronized network activity generated by the cerebral cortex. They consist of Up and Down states, which are periods of activity interspersed with periods of silence, respectively. However, even when this is a unique dynamic regime of transitions between Up and Down states, this pattern is not constant: there is a range of oscillatory frequencies (0.1–4 Hz), and the duration of Up vs. Down states during the cycles is variable. This opens many questions. Is there a constant relationship between the duration of Up and Down states? How much do they vary across conditions and oscillatory frequencies? Are there different sub regimes within the slow oscillation…
