The role of maternal support of competence, autonomy and relatedness in children's interests and mastery orientation

2013

Abstract The present study investigated the extent to which mothers' support for their children's sense of competence, autonomy and relatedness predicts their children's interest in math and reading, and also their mastery orientation, during the transition to primary school. One hundred fifty-two children were examined twice during their first grade year regarding their interests and mastery orientation (Time 1 and Time 2). Mothers filled in a diary and questionnaire measuring maternal support, also on two occasions (Time 1 and Time 2). Children's school performance in reading and math was tested at the beginning of the first grade (Time 1). The results showed that, after controlling for t…

Scaffolding for motivation by parents, and child homework motivations and emotions: Effects of a training programme

2018

Background and aims Based on the principles of scaffolding for motivation and on the assumptions of self-determination theory, two studies aimed to assess the role played by perceived parental autonomy-supportive scaffolding on child homework autonomous motivation, self-efficacy, affect, and engagement. Samples and results The results of Study 1, which involved 122 parents and their children, showed that the higher the parental autonomous motivation, the more their children perceived them as autonomy-supportive while scaffolding for motivation, and hence developed autonomous motivation, self-efficacy, and engagement in homework. In Study 2, 37 parents were involved in a four-session trainin…

Use of photoplethysmography to determine gastrointestinal perfusion pressure: an experimental canine model.

2002

<i>Objectives:</i> To develop an experimental model to assess the parietal perfusion pressure (PPP) of the digestive tract using photoplethysmography. <i>Materials and Methods:</i> Twenty-two mongrel dogs were used. Progressive external compression was applied to the intestinal wall and the PPP was assessed with photoplethysmography. The study group was divided into two groups. In group 1 PPP was measured at the levels of the stomach, duodenum, jejunum and transverse colon. In group 2 PPP was measured after temporary occlusion of the truncal and marginal circulation of the jejunum to provide further variables. <i>Results:</i> The PPP decreased significant…

Remote estimation of blood pulse pressure via temporal tracking of reflected secondary speckles pattern

2011

We present a novel technique for remote noncontact blood pulse pressure measurement. It is based on tracking both temporal and amplitude changes of reflected secondary speckle produced in human skin when illuminated by a laser beam. The implemented technique extracts the difference between the systolic and the diastolic blood pressure. Experimental results are presented showing good agreement when compared with conventional measurement methods.

Cortical function is impaired in various disorders of the central nervous system including Alzheimer’s disease, autism and schizophrenia. Some of these disorders are speculated to be associated with insults in early brain development. Pericytes have been shown to regulate neurovascular integrity in development, health and disease. Hence, precisely controlled mechanisms must have evolved in evolution to operate pericyte proliferation, repair and cell fate within the neurovascular unit (NVU). It is well established that pericyte deficiency leads to NVU injury resulting in cognitive decline and neuroinflammation in cortical layers. However, little is known about the role of pericytes in pathop…

Ilgtspējīgs izglītības atbalsts Kenijā: gadījumu izpēte par vietējo pašnoteikšanos starptautiskās attīstības palīdzības programmas ietvaros

2021

1966. gadā ANO Starptautiskā sociālā pakta (ICESCR) 13. un 14. pantā izglītība tika atzīta par vienu no cilvēktiesībām. Lai nodrošinātu šīs cilvēktiesības ikvienam, NVO izglītības jomā strādā, sniedzot atbalstu valstīm, kuras cīnās par kvalitatīvas izglītības mērķa sasniegšanu. Pretojoties arvien bezprincipiālākajai izglītības attīstības palīdzībai, kas pašlaik pieaug visā Eiropā, Nīderlandes NVO Teachers4Teachers strādā, lai īstenotu "varas maiņu", kad vietējie kenijieši pārņem Nīderlandes brīvprātīgo lomu izglītības attīstības palīdzības ietvaros. Izmantojot pieaugušo izglītības, psiholoģiskās pašnoteikšanās un atbildības teorijas, šajā pētījumā sniegti padomi, kā nodrošināt, lai šī pārma…

Facetten der Körperbildstörung: eine differenzielle Analyse des TEK-KJ (Test zur Erfassung der Körperbildstörung bei Kindern und Jugendlichen) zur di…

2018

Zusammenfassung. Zur Erfassung der haptisch-perzeptiven Komponente der Körperbildstörung – einem Kernkriterium der Essstörungen Anorexia nervosa und Bulimia nervosa – stehen nur sehr wenige gut evaluierte Verfahren zur Verfügung. In der vorliegenden Arbeit werden differenzielle Analysen zum Test zur Erfassung der Körperbildstörung bei Kindern und Jugendlichen (TEK-KJ) anhand einer großen Kinder- und Jugendlichenstichprobe dargestellt und zum ersten Mal Daten für männliche Kinder und Jugendliche ausgewertet. Dies beinhaltet die Prüfung der konvergenten Validität im Vergleich zur Contour Drawing Rating Scale (CDRS) und die Analyse von Unterschieden zwischen Kindern und Jugendlichen verschied…

Estimators and confidence intervals of f2 using bootstrap methodology for the comparison of dissolution profiles

2021

Abstract Background and objectives: The most widely used method to compare dissolution profiles is the similarity factor f 2 . When this method is not applicable, the confidence interval of f 2 using bootstrap methodology has been recommended instead. As neither details of the estimator nor the types of confidence intervals are described in the guidelines, the suitability of five estimators and fourteen types of confidence intervals were investigated in this study by simulation. Methods: One million individual dissolution profiles were simulated for the reference and test populations with predefined target population f 2 values, where random samples of different sizes were drawn without rep…

Comparison of Procedures to estimate Steady Flow Rate in Field Measurement of Saturated Hydraulic Conductivity by the Guelph Permeameter Method

1999

Abstract Different procedures for estimating steady flow rate during field application of the Guelph permeameter method were compared in terms of field-saturated hydraulic conductivity K fs and equilibration time t s estimates. The steady flow rate was evaluated by the slope of the linear portion of the cumulative drop in water level in the permeameter reservoir versus time plot (reference procedure) and by approximate procedures that use the first three or four consecutive values of the rate of fall of the water level equal or differing by less than a given percentage. The influence of the selected time interval between two successive readings ( Δt =2 or 10 min) at the permeameter was also…
