Uncertainties in polarimetric 3D reconstructions of coronal mass ejections
2015
P.P. acknowledges STFC for financial support. Date of Acceptance: 21/01/2015 Aims. The aim of this work is to quantify the uncertainties in the three-dimensional (3D) reconstruction of the location of coronal mass ejections (CMEs) obtained with the so-called polarization ratio technique. The method takes advantage of the different distributions along the line of sight of total (tB) and polarized (pB) brightnesses emitted by Thomson scattering to estimate the average location of the emitting plasma. This is particularly important to correctly identify of CME propagation angles and unprojected velocities, thus allowing better capabilities for space weather forecastings. Methods. To this end, …
La calidad periodística en España según la percepción de los periodistas
2015
Este artículo expone los resultados de una investigación sobre la percepción que tienen los periodistas españoles de la calidad periodística, teniendo en cuenta el contexto económico, tecnológico, empresarial, laboral y profesional. Los resultados de una encuesta, en la que participan 363 periodistas españoles con al menos tres años de experiencia en diferentes medios, ponen de manifiesto carencias relativas tanto a la relevancia y diversidad de los temas abordados como al acceso a las fuentes o el tratamiento y verificación de los datos, así como a las condiciones laborales o a los retos derivados de la adaptación a las nuevas tecnologías y a las imposiciones de la acuciante inmediatez.

CO2LD: An innovation educational project for High Degree Professional Training in Refrigeration
2013
EN] Refrigeration is one of the technology sectors that has sufered the most changes in the last twenty years, because of the negative impact of the fuids used in the refrigeration cycles, i.e., refrigerants, due to their impact on the ozone layer and their contribution to global warming. As a result of their negative efects, the European Union has established several directives to restrict the use of refrigerant fuids, and the sector therefore needs to adapt to the new regulations. This process of adaptation of the refrigeration sector to the new regulations must be carried out by all the agents involved, including those engaged in the training and education of the future refrigeration tec…
Effect of silica-type sol–gel carrier’s structure and morphology on a supported Ziegler–Natta catalyst for ethylene polymerization
2006
Abstract Silica xerogels with different structures and morphology, synthesized using a sol–gel procedure, were used as a carrier of vanadium catalysts (VOCl 3 /AlEt 2 Cl) for ethylene polymerization. Two techniques of catalyst synthesis were applied: slurry impregnation and gas-phase adsorption and the relevant polymerization methods were then employed. The effect of the carrier structure and morphology on the vanadium loading in the catalysts, the catalyst’s activity and kinetic stability were investigated.
Menores que Maltratan a sus Progenitores: definición Integral y su Ciclo de Violencia
2017
Dentro del maltrato familiar, la violencia filio-parental es una línea de investigación en el ámbito de la psicología y la pedagogía de cierta relevancia actual. En la primera parte del artículo se pretende analizar este fenómeno, desde las perspectivas psicoeducativa y jurídica, para aportar una definición integral que abarque diferentes perspectivas de la violencia filio-parental, porque la intervención y prevención de ésta debe partir del conocimiento acerca de las causas y mecanismos que intervienen en el complejo ámbito de ésta violencia intrafamiliar, así como de las relaciones e interacciones que se establecen entre hijos, hijas y progenitores. Por ello, la segunda parte del artículo…
Identities of special needs education in the discourse of Finnish professors of the field
2011
This article examines both the discourses upon which Finnish special needs education professors draw when speaking about their field, and the consequent identities for it. The research material consists of theme interviews with 10 professors of special needs education and is analysed from a socio-constructionist, discourse analytical perspective. The results show that the professors defined special needs education from two separate viewpoints: on the basis of their own personal views, or on the basis of the classical definitions of special needs education. The professors spoke about the field through five different discourses: professional, emancipatory, relativistic, autonomous and critica…
'Not as safe as I believed': Differences in perceived and self-reported cycling behavior between riders and non-riders
2021
Cycling behavior remains a key issue for explaining several traffic causalities occurring every day. However, recent studies have shown how the assessment of the own safety-related behaviors on the road may substantially differ from how third parties assess them. Thus, the aim of this study was to evaluate the differences between cyclists’ self-reported behavior and the proxy-reported behavior that other (non-cyclist) road users perceive from bike riders. For this purpose, this study used data from two samples: (i) 1064 cyclists (M = 32.83 years) answering the Cycling Behavior Questionnaire—CBQ, and (ii) 1070 non-cyclists (M = 30.83 years) answering an adapted version of the CBQ for externa…
Argumentation in Secondary School Students' Structured and Unstructured Chat Discussions
2012
Joint construction of new knowledge demands that persons can express their statements in a convincing way and explore other people's arguments constructively. For this reason, more knowledge on different means to support collaborative argumentation is needed. This study clarifies whether structured interaction supports students' critical and elaborative argumentation. The study compares the quality of secondary school students' argumentation during structured and unstructured chat interaction. The data consist of 16 dyadic chat discussions: 8 discussions concerned vivisection and 8 gender equality. Half of the discussions were carried out through structured chat, and the other half through…
Mobility Limitation and Changes in Personal Goals Among Older Women.
2016
Objectives. Several theoretical viewpoints suggest that older adults need to modify their personal goals in the face of functional decline. The aim of this study was to investigate longitudinally the association of mobility limitation with changes in personal goals among older women. Method. Eight-year follow-up of 205 women aged 66–78 years at baseline. Results. Health-related goals were the most common at both measurements. Goals related to independent living almost doubled and goals related to exercise and to cultural activities substantially decreased during the follow-up. Higher age decreased the likelihood for engaging in new goals related to cultural activities and disengaging from g…
Jotain uutta, jotain vanhaa, jotain lainattua : ikääntyneiden perhehoito Suomessa
2017
Tässä artikkelissa tarkastellaan ikääntyneiden perhehoitoa, jolla tarkoitetaan ikääntyneen henkilön lyhyt-, osa-aikais- tai pitkäaikaishoitoa ja asumista perhehoitajan kodissa. Artikkelin tarkoituksena on tunnistaa tekijöitä, jotka ovat perhehoidon taustalla ja joiden varassa perhehoitoa kehitetään ikääntyneiden hoivan yhdeksi vaihtoehdoksi. Lisäksi artikkelissa tarkastellaan perhehoitoa hoivapoliittisena ratkaisuna julkisen ja yksityisen rajalla semiformaaliuden ja (de)domestikaation käsitteiden kautta. Aineistona käytetään eduskunnan täysistuntojen pöytäkirjoja sekä perhehoito- ja perhehoitajalakeja ja näiden lakien hallituksen esityksiä, joita analysoidaan Carol Bacchin WPR-metodin avull…
