Survey of midwives' knowledge of caries prevention in perinatal care.
2014
Purpose To assess midwives' knowledge about oral health and early caries prevention during perinatal care for mothers and babies. Study design and methods A survey developed by the investigators was conducted among midwives to assess their knowledge about caries etiology, their attitude toward their role in early caries prevention, and prophylactic measures recommended during pregnancy, and after birth, for their babies. Self-administered questionnaires were sent to 180 midwives in hospitals and 323 midwives from a midwives' association in Hesse, Germany. Results Response rates were 46% (83/180) and 56% (181/323); a total of 264 questionnaires were evaluated. Most midwives were familiar wit…
Zarządcze aspekty logistyki jako determinanty rozwoju potencjałów strategicznych przedsiębiorstwa
2019
Przedsiębiorstwa stale poszukują sposobów tworzenia przewagi konkurencyjnej. W procesie budowania tej przewagi istotne znaczenie mają potencjały strategiczne przedsiębiorstwa, obejmujące przede wszystkim zasoby, zdolności oraz kompetencje. W rozwoju tych potencjałów ważną rolę odgrywa logistyka. Celem artykułu jest identyfikacja zarządczych aspektów logistyki oraz przesłanek ich oddziaływania na rozwój potencjałów strategicznych przedsiębiorstwa.
 Artykuł ma charakter koncepcyjny. Na początku przedstawiono pokrótce istotę logistyki jako koncepcji zarządzania przepływami towarów i informacji oraz najważniejsze fazy w jej rozwoju. Następnie zaprezentowano istotę i znaczenie potencjał…
Dynamiques de classe et efficacité scolaire
2003
The present research aims at describing the efficiency of teaching practices involved in dynamic "teaching-training" processes. Our main approach consisted in relating in-class-monitoring to the results of knowledge-acquisition by pupils so as to better explain through what means the pupils’ knowledge and competence are acquired. At a theoretical level this implies combining the "process-product" paradigm along with the "ecological" paradigm [ 1]. Results obtained indicate that bringing together the analysis of teaching practices with the evaluation of their impact "which are still limited to an exploratory stage" are a method well-worth pursuing. [ 1] See above the general introduction to …
Inhibition Probing on a Cut-Edge Electrode Machined from a Primer-Coated 2024-T3 Alloy
2013
Conventional corrosion protection of 2024-T3 alloys (AA2024T3) in aeronautic structures combines conversion coating with chromate-inhibited primer protected by a top-coat. In some cases this protection can break down after mechanical damage to the paint systems inducing a risk of localized corrosion if the release of inhibitors trapped in the primer does not reach a critical level. There is a need for developing computational models combining the inhibitor release and transport within and from the coating system andthecorrosioninhibitionprocess,toassistinthedesignofnewmultifunctionalcoatingsystems.Theinfluenceonthecorrosioninhibition of various parameters such inhibitor release rate, defect…
A probabilistic rainfall model to estimate the leading-edge lifetime of wind turbine blade coating system
2021
Rain-induced leading-edge erosion of wind turbine blades is associated with high repair and maintenance costs. For efficient operation and maintenance, erosion models are required that provide estimates of blade coating lifetime at a real scale. In this study, a statistical rainfall model is established that describes probabilistic distributions of rain parameters that are critical for site-specific leading-edge erosion assessment. A new droplet size distribution (DSD) is determined based on two years’ onshore rainfall data of an inland site in the Netherlands and the obtained DSD is compared with those from the literature. Joint probability distribution functions of rain intensities and dr…
Generating students' information seeking questions in the scholar lab: what benefits can we expect from inquiry teaching approaches?
2013
ABSTARCT: Physics teachers use experimental devices to show students how scientific concepts, principles, and laws are applied to understand the real world. This paper studies question generation of secondary and under-graduate university students when they are confronted with experimental devices in different but usual teaching situations: reading about devices while studying still images or diagrams, watching an experimental demonstration, and handling the devices in the laboratory. The influence of the prior scientific knowledge on the questions asked is also analysed. Inquiry learning environments, involving lab projects, seemed to stimulate more inferences addressed to causality when s…
Darsi codici etici in antropologia. Riflessioni a margine del processo di adozione del codice deontologico della Società Italiana di Antropologia App…
2016
Through review of selected anthropological ethical codes an attempt is made to outline the fundamental ethical principles of anthropological research and their applicability to current practices of applied anthropology. The Statement on Problems of Anthropological Research and Ethics was adopted by the American Anthropological Association in response to the need to take distance from military research after the Camelot scandal. Anthropology reacted stronger than other disciplines due to its methodology implying a relation of trust with the community. The Codice etico of AISEA defines the anthropologist’s obligations with different type of actors. In applied anthropology more attention shoul…
Sport arbitration as an emergent process in a complex system: Decision-making variability is a marker of expertise in national-level football referees
2020
This study examined the experiential knowledge of eight Australian national-level football referees (3.2 yrs mean national-level experience) about the notion of consistent decision-making during competitive matches. Using a grounded theory approach, the analysis revealed that participants view “consistency” as context-dependent, rather than a rigid process of uniformly responding to isolated foul-play transgressions with putatively correct responses. Our results present two key conceptual abstractions—”referential and game dependent” and “purpose and context”—as a framework for understanding referee decision-making consistency. Results evidence that in higher level referees, consistent deci…
Structural Knowledge Extraction from Mobility Data
2016
Knowledge extraction has traditionally represented one of the most interesting challenges in AI; in recent years, however, the availability of large collections of data has increased the awareness that “measuring” does not seamlessly translate into “understanding”, and that more data does not entail more knowledge. We propose here a formulation of knowledge extraction in terms of Grammatical Inference (GI), an inductive process able to select the best grammar consistent with the samples. The aim is to let models emerge from data themselves, while inference is turned into a search problem in the space of consistent grammars, induced by samples, given proper generalization operators. We will …
PEDAGOGICAL CONTENT KNOWLEDGE DEVELOPMENT AND PRE-SERVICE PHYSICS TEACHER EDUCATION: A CASE STUDY
2005
Abstract. This paper addresses the question of how to develop prospective teachers’ pedagogical content knowledge (PCK) in science teacher education. The main focus is on the knowledge transformation process and on the cognitive strategies used to shift prospective teachers’ explanations within the domain of modelling thermal physical phenomena. This study investigates the development of PCK within a group of 28 pre-service physics teachers during the first semester of their two-year post-graduate teacher education program. It focuses on the central issue of the relationships between observable phenomena, like macroscopic thermal properties of matter and their interpretation and /or explanat…
