Sediment delivery processes and chemical transport in a small forested basin
2005
Recent reaserch has directed attention to the properties of the eroded material because of its influence in deposition phenomena and in carrying capacity of pollutant materials
Computational Rationality as a Theory of Interaction
2022
Funding Information: This work was funded by the Finnish Center for AI and Academy of Finland (“BAD” and “Human Automata”). We thank our reviewers, Xiuli Chen, Joerg Mueller, Christian Guckelsberger, Sebastiaan de Peuter, Samuel Kaski, Pierre-Alexandre Murena, Antti Keuru-lainen, Suyog Chandramouli, and Roderick Murray-Smith for their comments. Publisher Copyright: © 2022 ACM. How do people interact with computers? This fundamental question was asked by Card, Moran, and Newell in 1983 with a proposition to frame it as a question about human cognition - in other words, as a matter of how information is processed in the mind. Recently, the question has been reframed as one of adaptation: how …
Opiskelijahuolto ja sosiaalityö toisen asteen ammatillisessa koulutuksessa
2008
Tutkimuksessa tarkastellaan toisen asteen ammatillisen koulutuksen opiskelijahuoltoa ja sosiaalityötä hallinnan analytiikan näkökulmasta. Tarkoituksena on sosiaalityön tehtävän ja asiantuntijuuden paikantaminen oppilaitosorganisaatiossa. Olen toteuttanut tutkimukseni kolmella toisen asteen ammatillisella oppilaitoksella käyttämällä eläytymismenetelmää, jossa keskeiset opiskelijahuollon toimijat kirjoittivat sekä onnistuneeseen että epäonnistu-neeseen lopputulokseen päättyneen opiskelijahuoltotarinan laatimani kehyskertomuksen pohjalta. Eläytymismenetelmätarinoita analysoimalla määrittelin viisi sosiaalityön ulottuvuutta; tul-kitsija ja tukija, koordinoija, sillanrakentaja, rinnalla kulkija …
Collaborative Design Rational and Social Creativity in Cultures of Participation
2011
The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three cas…
Spectroscopy of short-lived radioactive molecules
2020
Molecular spectroscopy offers opportunities for the exploration of the fundamental laws of nature and the search for new particle physics beyond the standard model1–4. Radioactive molecules—in which one or more of the atoms possesses a radioactive nucleus—can contain heavy and deformed nuclei, offering high sensitivity for investigating parity- and time-reversal-violation effects5,6. Radium monofluoride, RaF, is of particular interest because it is predicted to have an electronic structure appropriate for laser cooling6, thus paving the way for its use in high-precision spectroscopic studies. Furthermore, the effects of symmetry-violating nuclear moments are strongly enhanced5,7–9 in molecu…
Informed consent in dentistry and medicine in Spain: Practical considerations and legality.
2021
The healthcare practice of dentistry, as well as medicine, is framed within a legal environment. Patients have the right to know all the information related to any action performed on them and dental or medical doctors are obliged to obtain their patient?s prior written informed consent (IC) before undertaking any healthcare procedures. Here we reviewed the legality and jurisprudence in Spain regarding IC. We also used INFLESZ text readability analysis software to analyse a sample of official Spanish informed consent documents (ICDs) from different surgical and interventional procedures related to dentistry and oral cavity interventions. It is a mistake to confound IC with ICDs. This error …
Evidence of a non-conservative mass transfer in the ultra-compact X-ray source XB 1916-053
2020
The dipping source XB 1916-053 is a compact binary system with an orbital period of 50 min harboring a neutron star. Using ten new {\it Chandra} observations and one {\it Swift/XRT} observation, we are able to extend the baseline of the orbital ephemeris; this allows us to exclude some models that explain the dip arrival times. The Chandra observations provide a good plasma diagnostic of the ionized absorber and allow us to determine whether it is placed at the outer rim of the accretion disk or closer to the compact object. From the available observations we are able to obtain three new dip arrival times extending the baseline of the orbital ephemeris from 37 to 40 years. From the analysis…
La ecología del mirlo Turdus merula en los naranjales: un estudio a largo plazo
2015
Se estudiaron algunos aspectos demográficos y de la biología reproductiva del mirlo común Turdus merula en una superficie de 17 ha dedicada al cultivo del naranjo en la localidad valenciana de Sagunto. Mediante la aplicación mixta de la técnica de la parcela y de la búsqueda de nidos se calculó el número de parejas nidificantes desde 1975 hasta 2015 y se obtuvo información sobre el tamaño de la puesta, el éxito reproductor y las causas del fracaso de los nidos. El programa de anillamiento llevado a cabo en cuatro sesiones anuales desde el año 2000 hasta 2009 proporcionó información sobre la filopatria natal, la proporción de sexos y la supervivencia de los adultos. La variación estacional d…
Clinical Behavior of Short Dental Implants: Systematic Review and Meta-Analysis
2020
Short implants are an increasingly common alternative to other surgical techniques in areas where bone availability is reduced. Despite the advantages they offer, a variety of biological repercussions have been described in the literature that can even lead to the loss of these. The aim of this systematic review and meta-analysis was to analyze the impact of the use of short implants on their survival and on peri-implant bone loss, evaluating the influence that length, diameter, and crown-to-implant ratio (C/I) have on these parameters. This systematic review was based on guidelines proposed by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). An electronic se…
Structure and Photocatalytic Properties of TiO2-WO3Composites Prepared by Electrophoretic Deposition
2015
In this work TiO2-WO3 composite films containing different oxide concentrations were prepared by electrophoretic deposition on steel substrates. Composite coating structures were analyzed by X -ray diffraction, Raman spectra and scanning electron microscopy. The results showed an even distribution of WO3 particles in the entire composite layer. Light absorption measurements were used for photocatalytic properties evaluation. It was found that the removal ratio of methylene blue depends on the (TiO2):(WO3) concentration ratio. The most effective photodegradation was determined for the sample that was electrophoretically deposited from the suspension with the molar content ratio n(TiO2):n(WO3…
