Counselling for physical activity, life-space mobility and falls prevention in old age (COSMOS): protocol of a randomised controlled trial.
2019
IntroductionThe most promising way to promote active life years in old age is to promote regular participation in physical activity (PA). Maintaining lower extremity muscle function with good balance has been associated with fewer falls and the need of help from others. This article describes the design and intervention of a randomised controlled trial (RCT) investigating the effectiveness of a health and PA counselling programme on life-space mobility and falls rates in community-dwelling older adults at the Health Kiosk and/or Service Centre.Methods and analysisCommunity-dwelling men and women (n=450) aged 65 years and over with early phase mobility limitation will be recruited to a 24-mo…
Problems of the Constitutionalism of the Legal Norms related to the Restrictions of the Spread of Covid-19 infection
2022
Plašās diskusijas Latvijas sabiedrībā par Covid-19 infekcijas slimības ietekmē pieņemtajiem ierobežojumiem, to nozīmi un izpratni, kā arī Satversmes tiesā iesniegto pieteikumu skaits un ierosinātās lietas par iespējamo ar Covid-19 infekcijas slimības izplatības ierobežojumiem saistīto tiesību normu neatbilstību Satversmei norāda uz šī temata nozīmīgumu, kā arī uz to, ka par tiesību normās ietvertajiem ierobežojumiem nolūkā mazināt vīrusa slimības izplatību nav vienprātīgas nostājas. Pētījuma mērķis ir noskaidrot ar Covid-19 infekcijas slimības izplatības ierobežojumiem saistīto tiesību normu satversmības problēmas. Dažādu tiesību institūtu izpratne normatīvajos aktos un tiesību realitātē va…
High Nitrogen Removal in a Constructed Wetland Receiving Treated Wastewater in a Cold Climate
2018
Constructed wetlands provide cost-efficient nutrient removal, with minimal input of human labor and energy, and their number is globally increasing. However, in northern latitudes, wetlands are rarely utilized, because their nutrient removal efficiency has been questioned due to the cold climate. Here, we studied nutrient retention and nitrogen removal in a boreal constructed wetland (4-ha) receiving treated nitrogen-rich wastewater. On a yearly basis, most of the inorganic nutrients were retained by the wetland. The highest retention efficiency was found during the ice-free period, being 79% for ammonium-nitrogen (NH4+-N), 71% for nitrate-nitrogen (NO3--N), and 88% for phosphate-phosphorus…
Copolymerization of VDF and HFP in Supercritical Carbon Dioxide: A Robust Approach for Modeling Precipitation and Dispersion Kinetics
2012
A kinetic model is developed for the heterogeneous free-radical copolymerization of vinylidene fluoride and hexafluoropropylene in supercritical CO 2. The model accounts for polymerization in both the dispersed (polymer-rich) phase and in the continuous (polymer-free) supercritical phase, for radical interphase transport, diffusion limitations, and chain-length-dependent termination in the polymer-rich phase. A parameter evaluation strategy is developed and detailed to estimate most of the kinetic parameters a priori while minimizing their evaluation by direct fitting. The resulting model predictions compare favorably with the experimental results of conversion and MWD at varying monomer fe…
Segment duration in Finnish as imitated by Russians
2014
The paper reports findings of a study in which Russian speakers without any prior knowledge of Finnish imitated utterances in that language, and, in particular, how they succeeded in imitating segmental duration. The data was analysed using acoustic measurements of segment duration as well as auditory analysis by four judges. The results show that Russian speakers faced difficulties in imitating some aspects of the complicated Finnish quantity system. On the other hand, many of the imitated words were judged as comprehensible. Index Terms: duration, length, Finnish, imitation, language learning
Sing with the Telenoid
2012
We introduce a novel research proposal project aimed to build a robotic setup in which the Telenoid learns to improvise jazz singing in a duet with a human singer. In the proposed application, the Telenoid acts in teleoperated mode during the learning phase, while it becomes more and more autonomous during the working phase. A goal of the research is to investigate the essence of human communication which is based on gestures and prosody. We will employ an architecture for imitation learning that incrementally learns from demonstrations sequences of internal model activations, based on the idea of coupled forward- inverse internal models for representing musical phrases and the body sequenc…
Institutional Influences of Professional Associations and Franchise Organizations on Competitiveness of the Healthcare Clinics
2019
This paper uses insights from the institutional theory to study the competitiveness of the healthcare clinics in Spain. The environment of the healthcare services is highly institutionalized: professional associations are state agents responsible for the extensive regulation. Recently emerged franchise chains become subject for imitation by creating institutionalized routines from within and increasing competitive pressures for other industry players. While the sector is dominated by the independent doctors, franchise organizations are becoming more popular and show steady growth rates. The franchise business model in healthcare is evolving: while the core activity—provision of a healthcare…
Expert Q-learning: Deep Reinforcement Learning with Coarse State Values from Offline Expert Examples
2022
In this article, we propose a novel algorithm for deep reinforcement learning named Expert Q-learning. Expert Q-learning is inspired by Dueling Q-learning and aims at incorporating semi-supervised learning into reinforcement learning through splitting Q-values into state values and action advantages. We require that an offline expert assesses the value of a state in a coarse manner using three discrete values. An expert network is designed in addition to the Q-network, which updates each time following the regular offline minibatch update whenever the expert example buffer is not empty. Using the board game Othello, we compare our algorithm with the baseline Q-learning algorithm, which is a…
How Crime Spreads Through Imitation in Social Networks: A Simulation Model
2016
In this chapter an agent-based model for investigating how crime spreads through social networks is presented. Some theoretical issues related to the sociological explanation of crime are tested through simulation. The agent-based simulation allows us to investigate the relative impact of some mechanisms of social influence on crime, within a set of controlled simulated experiments.
Democratization Experiences and Obstacles in the South Caucasus: Possibilities for Change
2011
Democratization processes in the South Caucasus are still going on. Is the process feasible or it is just an imitation, which are the obstacles, challenges and achievements so far, as well as the solutions to the situation? These are the questions addressed in the paper.
