Development of a European consensus from dentists, dental hygienists and physicians on a standard for oral health care in care-dependent older people…
2020
ObjectivesThis study aimed to obtain a consensus on oral health policy, access to dental care, oral hygiene measures and training levels.BackgroundPoor oral health is widespread in care-dependent older people, but no consensus for a minimum standard of oral health care exists yet.MethodsThe e-Delphi approach was applied to a selected panel of interdisciplinary experts. Data analysis was based on three measurements: (a) ≥70% of experts’ opinion fall into category “agree or strongly agree,” (b) median score on the 5-point Likert scale ≥4, (c) interquartile range ≤1.ResultsA total of 31 experts from 17 European countries participated in this survey. Agreement was achieved for a compulsory dent…
Geophysics and cultural heritage. A living field of research for Italian geophysicists
2015
If one reads the World Heritage List 2002/2003, (http:// whc.unesco.org/archive/WHList02-ENG.pdf), a datum comes out with evidence: 12 countries have 253 World Heritage Sites (WHS) and all the 125 member countries have 586 WHS. Within these 12 countries Italy has 35 WHS corresponding to about 6% of the whole, followed by Spain, 5.8%, France, 4.6%, and the tenth has less than 2% of WHS. Cultural heritage is one of the greatest riches of Italy. Europe, with China, is the land which has the most stratified history in the world, and Italy is likely to still have undiscovered settlements dating from the prehistoric age to the 18th century. Some areas are totally unexplored, others have been only…
Ambient Art : Creative Information Representation
2007
Ambient art is the aesthetic presentation of information, using artistic techniques to achieve a pleasing image that also contains hidden depths, where exposure to it over time allows a viewer to understand something about the information sources that it represents. This paper reviews the artistic and computational background of ambient systems, and presents two case studies of systems developed by our research team, from their initial design to the experiences of the people encountering them. The first case presents a photo mosaic of images based on the news headlines coupled with a structured picture based on the weather; the second presents stylistic perspectives on activity in a public …
Runāšanas prasmju pilnveide, izmantojot stāstus
2016
Runāšanas prasmes tiek izmantotas katru dienu. Runa ir valodas prasme, kas palīdz komunicēt. Tas ir sarežģīts process, kas iekļauj citas valodu prasmes un runas orgānus. Tāpēc ir svarīgi attīstīt runāšanas prasmes. Bakalaura darba tēma ir "Runāšanas prasmju pilnveide, izmantojot stāstus". Darba mērķis ir pierādīt, ka, izmantojot stāstu metodi mācīšanā, var uzlabot runāšanas prasmes. Darbā izmantotās pētniecības metodes ir literatūras apskats, gadījumu izpēte un triangulācijas metode. Izvirzītā hipotēze tika pierādīta ar gadījuma izpētes metodi, balstoties uz iegūtajiem datiem no studentu aptaujām un iegūtajiem rezultātiem mācību stundas novērošanas laikā, un apstrādāti sekojošos izpētes dar…

Measurement of three-dimensional mirror parameters by polarization imaging applied to catadioptric camera calibration
2008
International audience; We present a new efficient method for calibration of cata- dioptric sensors. The method is based on an accurate measurement of the three-dimensional parameters of the mirror through polariza- tion imaging. While inserting a rotating polarizer between the cam- era and the mirror, the system is automatically calibrated without any calibration patterns. Moreover, this method permits most of the constraints related to the calibration of catadioptric systems to be relaxed. We show that, contrary to our system, the traditional meth- ods of calibration are very sensitive to misalignment of the camera axis and the symmetry axis of the mirror. From the measurement of three-di…
Optimized morphology and tuning the Mn3+ content of LiNi0.5Mn1.5O4 cathode material for li-ion batteries
2023
The advantages of cobalt-free, high specific capacity, high operating voltage, low cost, and environmental friendliness of spinel LiNi0.5Mn1.5O4 (LNMO) material make it one of the most promising cathode materials for next-generation lithium-ion batteries. The disproportionation reaction of Mn3+ leads to Jahn–Teller distortion, which is the key issue in reducing the crystal structure stability and limiting the electrochemical stability of the material. In this work, single-crystal LNMO was synthesized successfully by the sol-gel method. The morphology and the Mn3+ content of the as-prepared LNMO were tuned by altering the synthesis temperature. The results demonstrated that the LNMO_11…
On Ignoring the Random Effects Assumption in Multilevel Models: Review, Critique, and Recommendations
2019
Entities such as individuals, teams, or organizations can vary systematically from one another. Researchers typically model such data using multilevel models, assuming that the random effects are uncorrelated with the regressors. Violating this testable assumption, which is often ignored, creates an endogeneity problem thus preventing causal interpretations. Focusing on two-level models, we explain how researchers can avoid this problem by including cluster means of the Level 1 explanatory variables as controls; we explain this point conceptually and with a large-scale simulation. We further show why the common practice of centering the predictor variables is mostly unnecessary. Moreover, …
Variability of the Level of Development of Functopnal Urban Areas
2018
Miejskie obszary funkcjonalne mają istotne znaczenie w realizacji zarówno Krajowej Polityki Miejskiej 2023, jak i terytorialnej polityki rozwoju. Celem badania jest określenie poziomu rozwoju obszarów funkcjonalnych miast wojewódzkich Polski. Badania przeprowadzono z wykorzystaniem metody taksonomicznej w ujęciu dynamicznym obejmującym okres 2005-2015. Podstawę wyznaczenia wielkości taksonomicznych stanowił zestaw wskaźników diagnostycznych ujętych w trzech wymiarach rozwoju: społecznym, gospodarczym i środowiskowym. W ramach badania została podjęta ocena poziomu rozwoju miast centralnych MOF oraz oddzielnie miast i gmin ich otoczenia. Dodatkowo określono poziom rozwoju każdego z wymiarów r…
