Transformando las prácticas de evaluación en las agencias de innovación para fomentar transiciones hacia la sostenibilidad

2019

The aim of the study is to identify different styles and practices for evaluation of innovation policies based on different orientations, focusing on the case of the paradigm of transformative change to foster transitions towards sustainability, and the problems associated with its application. The study is exploratory, and it uses public funding agencies for innovation as strategic research settings. Based on the information provided by the experience of an international consortium participated by funding agencies from different countries, the main concepts and problems presented in the theoretical debate are illustrated. Finally, the main contributions of the study to the theory and pract…

The use of hydrogels in bone-tissue engineering

2010

Many different types of scaffold materials have been used for tissue engineering applications, and hydrogels form one group of materials that have been used in a wide variety of applications. Hydrogels are hydrophilic polymer networks and they represent an important class of biomaterials in biotechnology and medicine because many hydrogels exhibit excellent biocompatibility with minimal inflammatory responses and tissue damage. Many studies have demonstrated the use of hydrogels in bone-tissue engineering applications. In this report, the summary was conducted on various kinds of polymers and different modification methods of hydrogels to enhance bone formation. The results revealed that hy…

Improved Properties of the Big Five Inventory and the Rosenberg Self-Esteem Scale in the Expanded Format Relative to the Likert Format.

2019

Previous research by Zhang and Savalei (2015) proposed an alternative scale format to the Likert scale format: the Expanded format. Scale items in the Expanded format present both positively worded and negatively worded sentences as response options for each scale item; therefore, they were less affected by the acquiescence bias and method effects that often occur in the Likert scale items. The major goal of the current study is to further demonstrate the superiority of the Expanded format to the Likert format across different psychological scales. Specifically, we aim to replicate the findings of Zhang and Savalei and to determine whether order effect exists in the Expanded format scales. …

Do you study or work? The decision making in the training pathways of young people

2017

Este trabajo aborda el análisis de los discursos de los y las jóvenes en la toma de decisiones sobre sus itinerarios formativos y las transiciones escolares y entre escuela y trabajo. A partir de las entrevistas a jóvenes en dos proyectos de investigación, uno en itinerarios considerados como de “fracaso escolar y abandono prematuro” (educación obligatoria), y otro en itinerarios considerados de “éxito” (hacia la educación superior) pretendemos aproximarnos a los factores que influyen y dan sentido a las decisiones que toma el alumnado en sus diferentes posibilidades académicas. En este marco, la relación pedagógica se muestra como un elemento clave de vinculación con el centro escolar. Sin…

Measurement of dental implant stability by resonance frequency analysis : a review of the literature

2008

Dental implant treatment is an excellent option for prosthetic restoration that is associated with high success rates. Implant stability is essential for a good outcome. The clinical assessment of osseointegration is based on mechanical stability rather than histological criteria, considering primary stability (absence of mobility in bone bed after implant insertion) and secondary stability (bone formation and remodelling at implant-bone interface). The aim of this study was to review the literature on Resonance Frequency Analysis (RFA) as a method for measuring dental implant stability. An online search of various databases was conducted on experimental and clinical research published betw…

Depositional Environment of the Devonian Quartz Sandstones in the Bāle Sand Pits

2014

This paper summarises data about the depositional environment of Devonian quartz sandstones in Latvia and discusses new fieldwork data from Bāle 1 and Bāle 2 sand pits. The commercial bed in these sand pits is composed of fine to gravel size grained white and pale gray sandstones with mud clasts and quartz pebbles in places. Studies in Bāle sand pit sectors 1 and 2 suggest the deposition of sediments in details channel and sand bars, with the scarce influence of tidal processes on sedimentation.

Identity Formation, Personal Control Over Development, and Well-Being

2006

Individuals' conceptions of their personal goals have been studied in the psychology literature from different perspectives. In this chapter, the processes and implications of one's orientations and self-definitions were analyzed along two dimensions: one's sense of identity, and the self-percepts of autonomous control over development. Several researchers (e.g., Archer, 1989; Brandtstädter & Baltes-Götz, 1990; Pulkkinen & Rönkä, 1994) have concluded, on the basis of literature reviews and empirical findings, that adaptive capacities are associated with a clear sense of identity and personal control over development. Although any given cultural and historical context confines the possible a…

Serotoninergic innervation of nonprincipal cells in the cerebral cortex of the lizard Podarcis hispanica.

2004

The mechanism of serotoninergic transmission in the neo- and archicortex of mammals kis complex, including both synaptic and nonsynaptic components, direct actions on principal cells, and indirect effects mediated by GABAergic interneurons. Here we studied the termination pattern and synaptic organization of the serotoninergic afferents in the cerebral cortex of the lizard, Podarcis hispanica, which is considered to correspond in part to the mammalian hippocampal formation, with the aim of unraveling basic, phylogenetically preserved rules in the connectivity of this pathway. We demonstrate that serotoninergic afferents, visualized by immunostaining for serotonin itself, establish multiple …

Minireview: Nicotinic Acetylcholine Receptors on Hippocampal Neurons: Distribution on the Neuronal Surface and Modulation of Receptor Activity

1997

The recent development of a technique that uses infrared microscopy for the visualization of well-defined areas on the surface of neurons, and a computerized system of micromanipulators led to the discovery that functional nicotinic acetylcholine receptors (nAChRs) are expressed at higher density on the dendrites than on the soma of rat hippocampal neurons. The finding that the expression of alpha-bungarotoxin-sensitive, alpha 7-bearing, nAChRs and dihydro-beta-erythroidine-sensitive, alpha 4 beta 2 nAChRs tends to increase along the dendritic length suggests that these receptors may be highly involved in the integration of synaptic functions in hippocampal neurons. The present report also …
