Ubiquitous Structural Signaling in Bacterial Phytochromes
2015
The phytochrome family of light-switchable proteins has long been studied by biochemical, spectroscopic and crystallographic means, while a direct probe for global conformational signal propagation has been lacking. Using solution X-ray scattering, we find that the photosensory cores of several bacterial phytochromes undergo similar large-scale structural changes upon red-light excitation. The data establish that phytochromes with ordinary and inverted photocycles share a structural signaling mechanism and that a particular conserved histidine, previously proposed to be involved in signal propagation, in fact tunes photoresponse.
How to Write Ethical User Stories? : Impacts of the ECCOLA Method
2021
AbstractArtificial Intelligence (AI) systems are increasing in significance within software services. Unfortunately, these systems are not flawless. Their faults, failures and other systemic issues have emphasized the urgency for consideration of ethical standards and practices in AI engineering. Despite the growing number of studies in AI ethics, comparatively little attention has been placed on how ethical issues can be mitigated in software engineering (SE) practice. Currently understanding is lacking regarding the provision of useful tools that can help companies transform high-level ethical guidelines for AI ethics into the actual workflow of developers. In this paper, we explore the i…
Mineral profiles of legumes and fruits through partial least squares energy dispersive X-ray fluorescence
2019
Abstarct Energy dispersive X-ray fluorescence (ED-XRF) has been employed for the determination of mineral elements in 15 varieties of legumes and 14 cherry samples. ED-XRF signals directly obtained from pulverized samples were modelized by partial least squares (PLS) using Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) of a selected number of samples, after microwave assisted acid digestion, as reference data. Models were built to predict the concentration of Al, Ca, Cu, Fe, K, Mg, P, Sr and Zn. Average concentrations predicted were 6, 930, 7, 40, 6400, 990, 2100, 4 and 15 μg g−1 for Al, Ca, Cu, Fe, K, Mg, P, Sr and Zn, respectively with relative errors from 7 till 26%. …
ACTIVIDAD FÍSICA Y DISCAPACIDAD: UN ESTUDIO CUALITATIVO CON MUJERES EN UN GIMNASIO ADAPTADO
2017
Este estudio explora cómo un grupo de mujeres con discapacidad (n=6) experimentan y perciben la práctica de actividad física en un gimnasio adaptado. Se utilizaron entrevistas semi-estructuradas como instrumento de recogida de datos cualitativos y se realizó un análisis temático inductivo. Los resultados se agruparon en torno a cuatro categorías temáticas emergentes: condición física y autonomía personal; papel paliativo del ejercicio; bienestar psicológico; relación social y apoyo. Destaca la experiencia satisfactoria de las participantes, en la que predomina una valoración positiva de procesos autorregulativos, la concepción social-relacional de la actividad física, y la relevancia del gi…
Client’s role and participation in stroke physiotherapy encounters: an observational study
2016
AbstractClient participation is a basic principle in rehabilitation encounters. Coping at home after stroke requires self-confidence and autonomy, which can be enhanced by active collaboration and knowledge sharing. Earlier studies show, however, that clients are not always offered the role of an active participant in physiotherapy practice. A contradiction remains between official rhetoric and clinical practice. The purpose of this study was to investigate the interaction between the client and the physiotherapist in stroke rehabilitation sessions. Eight video-recorded treatment sessions were observed after an educational intervention that focused on client participation. Discourse analysi…
Ensuring Diverse User Experiences and Accessibility While Developing the TeSLA e-Assessment System
2019
The TeSLA project, with its new, innovative approaches for e-assessment, offers a great possibility for increasing the educational equality and making higher education studies available for all. It has been estimated that 10–15% of students in higher education institutions have some disabilities or special educational needs. At online universities or in online programmes, the number is even higher. These numbers emphasise the importance of the universal design for learning as a leading principle while developing the digital learning environments and e-assessment procedures. In this chapter, we describe the key elements of ensuring the accessibility of the TeSLA e-assessment system during th…
Me, Myself and I - Supporting People with Intellectual Disabilities Towards Self-determination
2020
The transition into work is challenging for people with intellectual disabilities (ID) and there are few digital services that support this process. The transition involves several organizations and professionals that need to collaborate and coordinate their documentation and their initiatives. This prototype paper describes a self-reflective career tool designed to support young adults with ID towards self-determination and transitions into work. The users are supported through features such as mapping of interests, skills and abilities, goal setting and progress overview. The prototype of the self-reflective career tool has been evaluated formatively and is continuously redesigned and fur…
Learning about students in co-teaching teams
2021
Teachers are facing increasingly diverse classrooms globally. To support all students efficiently, teachers need to know their students. Drawing from the literature of teacher learning and inclusive education, we explored how teachers learn to know their students in a co-teaching context. Analysis of interviews and diaries of five co-teaching teams showed that teachers learned about their students in a co-taught classroom by observing students and by obtaining knowledge from and co-constructing knowledge with their co-teaching partner. Moreover, teachers’ learning led to shared responsibility for the student and a better understanding of student diversity. Thus, sharing knowledge of student…
Rate of concurrent augmented auditory feedback in postural control learning in adolescents
2020
Introduction: The main objective of this study was to determine the rate of auditory concurrent feedback that best enhanced the learning of a continuous postural task in adolescents. Material and methods: A sample of thirty adolescents (13 to 14-years old) was used, who were assigned to three groups: i) control group (CG); ii) 100% auditory feedback group and iii) 67% auditory feedback group. The subjects performed a pre-test, practice, post-test and a retention (24 hours after the practice). In the postural control task subjects were instructed to remain on a seesaw (unstable in anteroposterior position) and keeping it as level as possible. Results: The results demonstrated that concurrent…
Long-term home-based physiotherapy for persons with signs of frailty–RCT (NCT02305433)
2018
Introduction/Background Frailty is a multidimensional condition, which can lead to disability. To postpone long-term care, one alternative is home-based physiotherapy. We study the effects of a 12-month home-based physiotherapy program on functional capacity, and applying successive 12-month register follow-up, on the use and costs of social and health care services, and on the duration of living at home during 24 months (the primary outcome). Here we report about feasibility of the intervention and baseline characteristics. Material and method Three hundred home-dwelling persons (>65 y) with signs of frailty were recruited by September, 2016. Frailty was screened by Morley's FRAIL question…
