Dynamic Modeling for Environmental Processes: A Case Study of Lake Engure
2014
Abstract This focus of the study was on system dynamic models that could be useful for modelling environmental processes in Lake Engure. The paper considers the system dynamic model development principles, the most important elements and structure. The aim of the study was to describe possible methods of ecosystem process modelling that allow to represent the actual state of ecosystems and provide opportunities to predict further processes. The methods of ecosystem modelling considered in the paper reveal interactive factors of anthropogenic and environmental processes that influence changes in ecosystems. System dynamic models indicate not only interactions between various factors in the e…
Assessment of Microstressors in Adults: Questionnaire Development and Ecological Validation of the Mainz Inventory of Microstressors
2020
Background Many existing scales for microstressor assessment do not differentiate between objective (ie, observable) stressor events and stressful cognitions or concerns. They often mix items assessing objective stressor events with items measuring other aspects of stress, such as perceived stressor severity, the evoked stress reaction, or further consequences on health, which may result in spurious associations in studies that include other questionnaires that measure such constructs. Most scales were developed several decades ago; therefore, modern life stressors may not be represented. Ecological momentary assessment (EMA) allows for sampling of current behaviors and experiences in real…
Spanish Validation of the Flourishing Scale in the General Population
2017
Well-being research and its measurement have grown in the last two decades. The objective of this study was to adapt and validate the Flourishing Scale in a sample of Spanish adults. This was a cross-sectional study using a non-probabilistic sample of 999 Spanish general adult population participants. The psychometric properties of the scale were analysed from an exploratory and confirmatory perspective. Exploratory factor analysis showed a one-factor solution explaining 42.3% of the variance; an internal consistency of .846; temporal reliability correlation of .749; convergent validity with the Satisfaction with Life Scale of .521 and criterion validity with positive and negative affect (P…
Simulation and validation of urban dynamics with cellular automata
2018
Cet article, rédigé en 2008, présente les évolutions importantes la plateforme SpaCelle pour simuler l'évolution d'un espace à l'aide d'automate cellulaire. En particulier, la version 5 permet la structuration multi-couches des cellules pour gérer la dynamique de plusieurs variables définies sur un maillage. Elle permet aussi d'utiliser des cellules de type linéaires ou ponctuelles à travers des couches de type réseau. Les différentes couches ont leur propre dynamique et les règles peuvent faire interagir les couches entre elles. Ces fonctionnalités avancées ont permis de construire un nouveau modèle sur l'évolution de l'agglomération rouennaise plus proche de la réalité terrain en utilisan…
Diseño y validación de un instrumento para evaluar la colegialidad docente
2016
El estudio trata de diseñar y validar un instrumento de evaluación de la colegialidad docente, como calidad de unión entre el profesorado de los centros docentes de educación primaria de España y México. El instrumento diseñado se basa en seis dimensiones: (1) valores éticos y profesionales compartidos; (2) cohesión y confianza en el grupo, actitudes de alianza, compañerismo; (3) compromiso con la tarea docente, actitud de mejora profesional continua; (4) toma de decisiones colegial sobre la tarea docente; (5) relaciones docentes colaborativas: autonomía y colectividad en la tarea docente, respeto y constructivismo en las relaciones interpersonales; (6) Clima dinámico y positivo del centro,…
The Psychometric properties of the resilience scale (RS-14) in Lithuanian adolescents
2021
In the current study, we provided the evidence of satisfactory validity of the RS-14 scale in the Lithuanian adolescents’ sample (N = 1299; Mage = 14.24; SDage = 1.26), based on its internal structure, and relations to other variables. The results of the study indicated an acceptable model fit for a single-factor structure of the scale with a high internal consistency (McDonald’s omega = 0.89). We also confirmed the scalar measurement invariance across groups of adolescents in terms of their age (i.e., early and middle adolescence) and mental health profile as well as partial scalar gender invariance. Adolescents characterized by high levels of socio-emotional problems reported lower levels…

Sasniedzamie rezultāti valodas kultūras jautājumu apguvē vidusskolā
2022
Bakalaura darba Sasniedzamie rezultāti valodas kultūras jautājumu apguvē vidusskolā mērķis ir analizēt, kādi skolēnam sasniedzamie rezultāti valodas kultūras jautājumu apguvē ir iestrādāti vidusskolas mācību saturā. Darbā izmantoti pētījumi par sasniedzamajiem rezultātiem mācību procesa veidošanā, un aplūkoti Ministru kabineta noteikumi Nr. 416 par valsts vispārējās vidējās izglītības standartu. Darba praktiskajā daļā analizēti pieejamie vidusskolas mācību materiāli par valodas kultūru, salīdzinot tos ar Ministru kabineta noteikumos izstrādātajiem sasniedzamajiem rezultātiem. Darbā secināts, ka latviešu valodas mācību saturu vidusskolai ir nepieciešams pārveidot, ņemot vērā jaunākos Ministr…
Valodas modeļi latviešu runas atpazīšanas sistēmai
2015
Automātiskā runas atpazīšanas sistēma (no angļu valodas automatic speech recognition – ASR) ir tāda sistēma, kas cilvēka izrunātos vārdus pārvērš tekstā. Tās pamata divas sastāvdaļas ir akustiskais un valodas modelis. Darba mērķis ir detalizēti apskatīt metodes, ar kurām tiek trenēti valodas modeļi, kā arī pārbaudīt, kā labākās no tām darbojas latviešu runas atpazīšanā. Valodas modeļu trenēšanā tika izmantotas brīvi pieejamās rīkkopas KenLM un SRILM. Runas atpazīšanas eksperimentos, kuros tika izmantota brīvi pieejamā runas atpazīša- nas rīkkopa Kaldi, tika identificētas problēmas, kādas rodas, valodas modeļus pielietojot runas atpazīšanai klasiskā veidā. Modificējot klasisko pieeju, ar kur…
