Achievement emotions and arithmetic fluency : Development and parallel processes during the early school years
2023
This study investigated the developmental trajectories and interrelationships of mathematics-related achieve-ment emotions and arithmetic fluency from first to third grade, and the effects of these on third grade mathe-matics performance. Participants were 232 Norwegian students. Students' emotions and arithmetic fluency were measured four times and mathematics performance once. Applying latent growth curve modeling, developmental patterns of decreasing enjoyment and increasing boredom were observed over time. The mean level of enjoyment remained fairly high, and of both boredom and anxiety quite low. Individual differences were observed in both the initial levels and development of all emo…
Effect of active application of self-etching ceramic primer on the long-term bond strength of different dental CAD/CAM materials
2021
Made available in DSpace on 2022-04-29T08:36:43Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01 Background: The objective of this in vitro study was to evaluate the effect of the active application of self-etching ceramic primer (ME&P) on the bond strength of different dental CAD/CAM materials (Lithium Disilicate ceramic (LD), Leucite ceramic (LE), Zirconia reinforced lithium silicate ceramic (ZLS), and Hybrid ceramic (HC)) with thermocycling aging. Material and Methods: The samples were randomly divided into 16 groups (n = 20). Dual resin cement cylinders were made and light cured for 10 s (1.200 mW/cm2) for the shear bond strength test. 3-way ANOVA revealed that the factors w…
Incentives, criminal defence lawyers and plea bargaining
2008
Plea bargaining has become a central feature of criminal procedure in Anglo-Saxon jurisdictions. This paper explores an area seldom discussed in the economic literature on plea bargaining: the influence of the defence lawyer's fee contract on the terms of the bargain. In particular, it uses data from one jurisdiction of the impact on case trajectories of changes in publicly funded defence lawyers’ contracts to test the proposition that the nature of the lawyer's contract influences how cases are managed. An event study methodology on a pooled time-series cross-section data set of case trajectories before and after the change in the nature of the contract is used to examine whether the new p…
CheS-Mapper - Chemical Space Mapping and Visualization in 3D
2012
Abstract Analyzing chemical datasets is a challenging task for scientific researchers in the field of chemoinformatics. It is important, yet difficult to understand the relationship between the structure of chemical compounds, their physico-chemical properties, and biological or toxic effects. To that respect, visualization tools can help to better comprehend the underlying correlations. Our recently developed 3D molecular viewer CheS-Mapper (Chemical Space Mapper) divides large datasets into clusters of similar compounds and consequently arranges them in 3D space, such that their spatial proximity reflects their similarity. The user can indirectly determine similarity, by selecting which f…
University Teachers’ Professional Identity Work and Emotions in the Context of an Arts-Based Identity Coaching Program
2020
In changing work contexts, there is a critical need to adopt practices that support professional identity work in order to promote individuals’ resilience and well-being at work. This chapter reports on an investigation into professional identity work and emotions in the context of an arts-based coaching program aimed at prompting experienced university teachers to process their professional identities. Since different (un)pleasant emotions emerged during the program, the chapter notably discusses the advantages and pitfalls of using arts-based methods among adults. The findings also contribute to the theoretical understanding of the role of emotions in professional identity processes by re…
Negotiation mechanisms for capacity allocation in distributed enterprises
2003
Abstract The paper proposes an agent based approach for the capacity allocation in distributed enterprises, characterized by complex and articulated organizations and by geographically distributed production capacities contended by many product families. In such a scenario the process of allocating the production capacity to the single customer order is one the major bottlenecks of the production planning activity as far as many organizational decisional levels are involved and market turbulence implies a continuous retuning of the capacity allocation plan. A high grade of reactiveness is needed. Agent based approaches and negotiation models, by decentralizing the decisional control and sim…
How to combine tools and methods in practice— a field study
1990
In spring 1989 we surveyed the experiences of some Finnish companies in methodology modelling (metamodelling) and adaptation of tools and methodologies to each other (methodology adaptation). The companies represented software production, banking, wood and metal industry, and wholesale trade. The study was carried out as a field study where we interviewed method developers, systems analysts and their supervisors. The goal of the survey was to find out whether there was need for metamodelling or methodology adaptation in general and how this need had been satisfied. The study shows that a little experience had been gained in adapting data dictionaries to methodologies but no such attempts ha…
Aims vs. technology: Pedagogical view to the use of educational applications in safety critical contexts
2011
Interactive technology for education has formed into a relatively independent domain of research and development. Interactive technology is often seen as a context independent tool. However, we argue that education in different contexts may have so different and incommensurable aims that no single technology can be announced as good or bad per se in terms of learning. The development of educational application should not be based on the technology to be applied, but by careful analysis of learning aims. When formulated in an appropriate way, learning aims work as a relevant basis in all stages of the design process of an educational application. The formulation of aims is therefore critical…
Sérologie discordante du VIH/sida et vie des couples en République du Congo : profil sociodémographique, comportements, facteurs de survie et prise e…
2020
For more than two decades, the health of populations has been at the heart of developmental issues. Population health issues fall within the "health, population and development" paradigm. It is in this spirit that experts demonstrated at the 1994 Cairo Conference on Population and Development that HIV/AIDS affects both population growth and sustainable development. Likewise, HIV infection is a source of discrimination, social inequalities, and the weakening of couples and families to the point where some individuals are even ostracized because of their HIV-positive status. In these conditions, how do people of different serological status live their married lives and their procreation despi…
The triaminopyridine flupirtine prevents cell death in rat cortical cells induced by N-methyl-D-aspartate and gp120 of HIV-1.
1994
Abstract Flupirtine, a triaminopyridine derivative, is a non-opiate centrally acting analgesic agent with muscle relaxant properties. Now we show that this drug displays a potent cytoprotective effect on neurons (rat cortical cells) treated with (i) the excitatory amino acid N-methyl- d -aspartate (NMDA) or (ii) with the human immunodeficiency virus type 1 (HIV-1) coat protein gp120. In the absence of the drug the two agents cause a >90% reduction of cell viability after a 18 h incubation. During this period the DNA in the cells undergoes fragmentation and shows a pattern which is typical for cell death. If the neurons were preincubated with flupirtine for 2 h and subsequently exposed to th…
