Työhyvinvointivalmennuksen vaikutukset koettuun ja sykkeen avulla mitattuun stressiin
2012
Yritykset ovat aidosti huolissaan avainhenkilöidensä työssä jaksamisesta ja työstä palautumisesta. Eri-tyisen huolen aiheena on raskaasta ja kuluttavasta työtaakasta palautuminen. Raskas työ ei nykymitta-reilla osoitettuna vaadi enää palautumiseen raskasta huvia, vaan hyvinkin rauhallisen, mahdollisesti liikunnallisesti aktiivisen palautumisjakson. Hyvä palautuminen näkyy myös kotiarjessa aktiivisena, elämänmyönteisenä tekemisenä. Tutkimuksen tarkoituksena oli selvittää, kehittääkö 6 - 9 kuukautta kestävä työhyvinvointivalmennus-jakso, interventio, tutkittavissa henkilöissä parempaa työperäisen stressin sietokykyä ja kehittyykö hei-dän palautumiskykynsä. Tutkimuksessa selvitettiin, onko int…
Optimisation algorithms in the case of mineral detection using Raman Analysis
2013
Abstract Raman analysis can be used to analyse the existence of minerals in an ore sample. Especially the interest here is to analyse given ore sample rapidly, to find out what minerals it contains. Rapid analysis would enable more rapid exploration of minerals as analysis could be carried out on-site. For this study, ore samples were collected from two mines in Northern Finland, Kittila and Kevitsa. An optimisation algorithm was constructed to form a linear combination of reference spectra which best represent the measured spectrum from an ore sample. The reference spectra were collected from a public source. It was found that solving for an optimal summation of reference spectra can be a …
Arm Space Decomposition as a Strategy for Tackling Large Scale Multi-armed Bandit Problems
2013
Recent multi-armed bandit based optimization schemes provide near-optimal balancing of arm exploration against arm exploitation, allowing the optimal arm to be identified with probability arbitrarily close to unity. However, the convergence speed drops dramatically as the number of bandit arms grows large, simply because singling out the optimal arm requires experimentation with all of the available arms. Furthermore, effective exploration and exploitation typically demands computational resources that grow linearly with the number of arms. Although the former problem can be remedied to some degree when prior knowledge about arm correlation is available, the latter problem persists. In this…
Efficacy of the cloud computing technology in the management of communications and business processes of the companies
2016

Zaprezentowano krótki przegląd aktualnego stanu wykorzystania technologii chmury obliczeniowej na świecie i na Ukrainie. Korzyści wynikające z zastosowania modelu "SaaS - Software as a Service" zostały wyjaśnione na przykładzie innowacji międzynarodowego projektu "Bitrix 24", w którym zrealizowane zostały główne cele systemów CRM w połączeniu z szerokimi możliwościami koordynacji procesów komunikacyjnych i biznesowych nowoczesnych firm. Projekt ten został przetłumaczony na większość języków europejskich i wykorzystuje narzędzia społecznego środowi…
Sāpju novērtēšana bezsamaņā esošam pacientam ar spontānu elpošanu
2019
Bakalaura darba tēma- Sāpju novērtēšana pacientiem bezsamaņā ar spontānu elpošanu. Tēma tika izvēlēta balstoties uz autores personīgo pieredzi un interesi par pacientiem bezsamaņā ar spontānu elpošanu. Pētījumi ārzemēs apstiprina to, ka sāpju kontrolei ir nepieciešama indivuduāla pieeja, lai uzlabotu sāpju novērtēšanu un pārvaldību. Tāpēc nepieciešams nepārtraukti attīstīties, pilnveidoties un uzlabot māsu sadarbību ar pacientiem bezsamaņā kā arī pilveidot un attīstīt sāpju novērtēšanas protokolus bezsamaņas pacientiem arī Latvijas praksē. Joprojām aktuāli jautājumi kā adekvāti novērtēr sāpes pacientam esot bezsamaņā un kā sadarboties un komunicēt ar pacientu bezsamaņā ar spontānu elpošanu …
Measuring Distraction at the Levels of Tactical and Strategic Control: The Limits of Capacity-Based Measures for Revealing Unsafe Visual Sampling Mod…
2011
The control theory of driving suggests that driver distraction can be analyzed as a breakdown of control at three levels. Common approach for analyzing distraction experimentally is to utilize capacity-based measures to assess distraction at the level of operational control. Three driving simulation experiments with 61 participants were organized to evaluate which kind of measures could be used to analyze drivers' tactical visual sampling models and the related effects of distraction while searching textual information on in-car display. The effects of two different text types were evaluated. The utilized capacity-based measures seemed to be insufficient for revealing participants' tactical…
Mobile Banking Services Continuous Usage -- Case Study of Finland
2016
Finland is at the forefront of using new information systems, such as mobile banking (m-banking). The present study develops and tests a model of continuous usage intentions toward m-banking services for a sample of 273 Finnish m-banking users. Results confirm the hypothesized direct relationships between self-congruence and perceived value, perceived risk and perceived value, perceived value and continuous usage, and continuous usage and word of mouth. The frequency of usage of m-banking services and experience moderate the relationship between perceived value and continuous usage. We discuss the theoretical and managerial implications of the study results and present recommendations for f…
The challenges of analysing blood stains with hyperspectral imaging
2014
Hyperspectral imaging is a potential noninvasive technology for detecting, separating and identifying various substances. In the forensic and military medicine and other CBRNE related use it could be a potential method for analyzing blood and for scanning other human based fluids. For example, it would be valuable to easily detect whether some traces of blood are from one or more persons or if there are some irrelevant substances or anomalies in the blood. This article represents an experiment of separating four persons' blood stains on a white cotton fabric with a SWIR hyperspectral camera and FT-NIR spectrometer. Each tested sample includes standardized 75 _l of 100 % blood. The results s…
SERS detection of cell surface and intracellular components of microorganisms using nano-aggregated Ag substrate
2016
Abstract The intracellular and cell surface composition and structural features of gram-positive and gram-negative bacteria were identified using near-infrared surface-enhanced Raman scattering (SERS). The structural differences of components that reside in the cell envelope are manifested by their SERS spectra, e.g. gram-negative vs. gram-positive. Silver particles were used as a SERS substrate by exploiting the existence of strong local electromagnetic fields (hot spots) within nanoscale aggregates of the particles. The aggregation of silver nanoparticles was induced by magnesium ions. These hot spots reduce the screening length of the double layer. The obtained SERS spectra showed excell…
Behavior change types with Pokémon GO
2017
Digital games1 are one of the most popular entertainment media in the world. Teir allure and widespread popularity makes them an interesting and highly potential platform for behavior change atempts. In this paper, we investigate what types of behavior changes Pokémon GO has promoted or induced among its players. Te study is based on an online survey sample of 262 Pokémon GO players, collected using the critical incident technique and analyzed using qualitative methods. Te analysis shows that the behavior changes induced by Pokémon GO are not just restricted to increased physical activity or social behavior but are actually much more multifaceted: players were more social, found their routi…
