Brīvprātīgo pieredzes darbā ar dzimumnoziedznieku resocializāciju Atbildīguma un atbalsta apļos
2020
Maģistra darba mērķis ir izpētīt brīvprātīgo iesaistīšanos un pieredzes Valsts probācijas dienesta organizētajos Atbildīguma un atbalsta apļos darbā ar dzimumnoziedznieku resocializāciju. Ņemot vērā, ka sabiedrībā valda kritiska un noraidoša attieksme pret dzimumnoziedzniekiem, ar šī darba palīdzību vēlos identificēt iemeslus, kādēļ brīvprātīgie piesakās darbam Apļos, kādas ir viņu attieksmes pret dzimumnoziedzniekiem, kādi viņu izpratnē ir dzimumnoziegumu cēloņi, un kurus no tiem var risināt Atbildīguma un atbalsta apļi. Galvenie secinājumi ir, ka iemesli piedalīties dzimumnoziedznieku resocializācijā saistāmi ar vēlēšanos būt noderīgam sabiedrībai, kā arī personīgā un profesionālā redzesl…
Veselības aprūpes finansēšanas problēmas
2016
Bakalaura darba tēma „Veselības aprūpes finansēšanas problēmas”. Latvijas veselības aprūpes organizēšanas un finansēšanas sistēmā izveidojušas nopietnas problēmas. Bakalaura darbs „Veselības aprūpes finansēšanas problēmas ” mērķis apskatīt veselības aprūpes finansējuma modeļus Latvijā un pasaulē. Izmantojot jaunākos datus, izpētīt kādā situācijā ir Latvijas medicīna relatīvi pret citām vadošajām pasaules valstīm, noskaidrot primāro veselības aprūpes finansējumu un veselības aprūpes pieejamību dzīvojošajiem Baltijas valstīs, un uz veiktās izpētes pamata sagatavot atsevišķas rekomendācijas obligātās veselības aprūpes apdrošināšanas ieviešanu Latvijā.

Some Features of Modeling Ultrasound Propagation in Non-Destructive Control of Metal Structures Based on the Magnetostrictive Effect
2023
A method and mathematical models of direct and inverse problems of ultrasonic testing and diagnostics of complex metal structures for defects were developed and tested. A prototype of a system for magnetostrictive control of elements of the objects under study was manufactured and experimentally tested. Mathematical simulation of ultrasonic testing processes using MATLAB and the COMSOL Multiphysics software environment was carried out. The adequacy of the mathematical models was verified by the results of their comparison with real physical experiments. Information support and a methodology that implements it was developed, which ensure the functioning of the control facilities for these ob…
Essays on Employment and Unemployment Transitions
2015
The Great Recession has led to important adjustments in the labour market of most developed countries and has dramatically affected the labour market in Spain. According to the Labour Force Survey, the Spanish unemployment rate has increased drastically from 8.5% in 2006 to 25% in 2012 (see the figure). In order to understand the unemployment rate it is important to consider both entry into and exit out of unemployment. This thesis addresses relevant questions for policymakers in line with the objectives of the Europe 2020 strategy. How does the Great Recession affect the patterns and determinants of durations of unemployment and new job matches? How did gender differences in labour market …
贝叶斯因子及其在JASP中的实现
2018
Statistical inference plays a critical role in modern scientific research, however, the dominant method for statistical inference in science, null hypothesis significance testing (NHST), is often misunderstood and misused, which leads to unreproducible findings. To address this issue, researchers propose to adopt the Bayes factor as an alternative to NHST. The Bayes factor is a principled Bayesian tool for model selection and hypothesis testing, and can be interpreted as the strength for both the null hypothesis H0 and the alternative hypothesis H1 based on the current data. Compared to NHST, the Bayes factor has the following advantages: it quantifies the evidence that the data provide for…
A concept for personal wellness management based on activity monitoring
2008
Lifestyle related health problems are increasing rapidly. Many of them could be prevented or alleviated by sufficient physical activity, enough sleep, and a balanced diet. Individual citizens have the main responsibility for their own health and wellness management in their daily lives. Motivational tools based on modern technologies can support people in this task. Vivago Personal Wellness Manager (PWM) is a concept for personal wellness management, based on continuous activity monitoring with a wrist-worn device combined with immediate feedback on daily activity, e.g., sleep and physical activity. The concept allows long-term monitoring of activity patterns and includes PC software for de…
Ensemble feature selection with the simple Bayesian classification
2003
Abstract A popular method for creating an accurate classifier from a set of training data is to build several classifiers, and then to combine their predictions. The ensembles of simple Bayesian classifiers have traditionally not been a focus of research. One way to generate an ensemble of accurate and diverse simple Bayesian classifiers is to use different feature subsets generated with the random subspace method. In this case, the ensemble consists of multiple classifiers constructed by randomly selecting feature subsets, that is, classifiers constructed in randomly chosen subspaces. In this paper, we present an algorithm for building ensembles of simple Bayesian classifiers in random sub…
Fuzzy temporal random sets with an application to cell biology
2007
Total Internal Reflection Fluorescence Microscopy (TIRFM) greatly facilitates to imaging the first steps of endocytosis, a process whereby cells traffic cargo from the cell surface to endosomes. Using TIRFM, fluorescent-tagged endocytic proteins are observed as overlapped areas forming random clumps of different sizes, shapes and durations. A common procedure to segment these objects consists of thresholding the original gray-level images to produce binary sequences in which a pixel is covered or not by a given fluorescent-tagged protein. This binary logic is not appropriate because it leaves a free tuning parameter to be set by the user which can influence on the conclusions of the statist…
Psychophysical response to electrocutaneous stimulation.
1984
A method is presented to determine a reliable stimulus-sensation relationship particularly suitable for electrocutaneous stimulation. An experimental intensity-discrimination curve was obtained through simple psychophysical comparison tasks, and sensory response was inferred from integration of a JND's density function. The psychophysical response resembles a power law, although departures cannot be described in terms of a unique exponent. An estimate of binary information capacity per electrode is also given as a feature of a stimulation procedure that preserves a low value of the size-intensity product.
Modeling user preferences in content-based image retrieval: A novel attempt to bridge the semantic gap
2015
This paper is concerned with content-based image retrieval from a stochastic point of view. The semantic gap problem is addressed in two ways. First, a dimensional reduction is applied using the (pre-calculated) distances among images. The dimension of the reduced vector is the number of preferences that we allow the user to choose from, in this case, three levels. Second, the conditional probability distribution of the random user preference, given this reduced feature vector, is modeled using a proportional odds model. A new model is fitted at each iteration. The score used to rank the image database is based on the estimated probability function of the random preference. Additionally, so…
