Loss of spatial learning in a patient with topographical disorientation in new environments

2003

The case is described of a patient who, following cerebral hypoxia, developed severe difficulty in orienting himself in new environments in the context of a mild global amnesic syndrome. Some episodes he related suggested that his main difficulty was remembering the spatial/directional value of landmarks he recognised. A neuroradiological examination documented severe bilateral atrophy of the hippocampi associated with atrophic changes in the cerebral hemispheres, most marked in the dorsal regions. Neuropsychological and experimental evaluation showed a severe deficit of spatial learning with substantially preserved ability to learn verbal and visual-object information. He was also virtuall…

Hydrodynamics with spin in bacterial suspensions

2016

We describe a new kind of self-propelling motion of bacteria based on the cooperative action of rotating flagella on the surface of bacteria. Describing the ensemble of rotating flagella in the framework of the hydrodynamics with spin the reciprocal theorem of Stokesian hydrodynamics is generalized accordingly. The velocity of the self-propulsion is expressed in terms of the characteristics of the vector field of flagella orientation and it is shown that unusually high velocities of \textit{Thiovulum majus} bacteria may be explained by the cooperative action of the rotating flagella. The expressions obtained enable us to estimate the torque created by the rotary motors of the bacterium and …

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…

Trading Data for Health

2021

mHealth apps are growing in popularity among smartphone users. Such apps often contain social features that enable users to compare their behavior with others but to function, mHealth apps require users to share health information which is considered a threat to individuals’ privacy. Building on social comparison theory and research on privacy decision-making, we investigate the effects of users’ social comparison orientation and privacy attitudes as well as the potential mediating effect of health information disclosure on users’ intention to use a dietary app. Relying on a PLS-based structural-equation model in a sample of N = 528 participants, our study supports claims of a positive effe…

Market orientation, trust and satisfaction in dyadic relationships:a manufacturer‐retailer analysis

2003

This paper studies the relationships between the manufacturer's market orientation behaviours and the distributor's trust in the relationship and satisfaction with it. It also analyses the effect of the distributor's trust on his/her satisfaction. Following a review of the literature, three alternative models of relationships between trust and satisfaction are compared. For this purpose the article presents the results of a study of the Spanish ceramic industry. These establish that the effect of the manufacturer's market orientation on the distributor's trust and on its satisfaction with the relationship is different depending on which dimension is considered. The model that best fits the …

X-ray-diffraction study of the crystal structures and orientational glass state ofAr1−x(N2)xsolid solutions

1990

Solid solutions of ${\mathrm{Ar}}_{1\mathrm{\ensuremath{-}}\mathit{x}}$(${\mathrm{N}}_{2}$${)}_{\mathit{x}}$ have been investigated by x-ray powder diffraction in the range 0.5x1.0, 8T60 K, and under hydrostatic pressures up to 2200 bars. The structural hcp-cubic (Pa3) phase transition is identified as a martensitic transformation with a wide transformation hysteresis. For x0.8 and T30 K the solid solutions show the orientational glass state, which is characterized by a superposition of inhomogeneous and homogeneous lattice strains. The inhomogeneous component is described by the random-field model. The homogeneous component corresponds to an orthorhombic distortion of the hcp lattice. Two …

Estimation of orientation characteristic of fibrous material

2001

A new statistical method for estimating the orientation distribution of fibres in a fibre process is suggested where the process is observed in the form of a degraded digital greyscale image. The method is based on line transect sampling of the image in a few fixed directions. A well-known method based on stereology is available if the intersections between the transects and fibres can be counted. We extend this to the case where, instead of the intersection points, only scaled variograms of grey levels along the transects are observed. The nonlinear estimation equations for a parametric orientation distribution as well as a numerical algorithm are given. The method is illustrated by a real…

Gesture's body orientation modulates the N400 for visual sentences primed by gestures

2020

Abstract Body orientation of gesture entails social‐communicative intention, and may thus influence how gestures are perceived and comprehended together with auditory speech during face‐to‐face communication. To date, despite the emergence of neuroscientific literature on the role of body orientation on hand action perception, limited studies have directly investigated the role of body orientation in the interaction between gesture and language. To address this research question, we carried out an electroencephalography (EEG) experiment presenting to participants (n = 21) videos of frontal and lateral communicative hand gestures of 5 s (e.g., raising a hand), followed by visually presented …

A Descriptive Case Analysis of Instructional Teaching Practices in Finnish Preschool Classrooms

2013

This study examined the diversity of teaching practices to illuminate the qualitative variety of instructional teaching practices among preschool teachers. Further, teachers' self-rated educational goals were explored to complement the multifaceted nature of preschool teachers' instructional teaching practices. The study was carried out as a case study. The cases were used to describe the qualitative variety of Finnish preschool teachers' instructional practices in authentic classroom situations among groups of 6-year-old children. The authors' previous study revealed four distinct latent profiles of teaching practices in preschool classrooms based on 49 observed preschool teachers, using t…
