Statistical properties of general Markov dynamical sources: applications to information theory
2004
In \textitDynamical sources in information theory: fundamental intervals and word prefixes, B. Vallée studies statistical properties of words generated by dynamical sources. This is done using generalized Ruelle operators. The aim of this article is to generalize sources for which the results hold. First, we avoid the use of Grotendieck theory and Fredholm determinants, this allows dynamical sources that cannot be extended to a complex disk or that are not analytic. Second, we consider Markov sources: the language generated by the source over an alphabet \textbfM is not necessarily \textbfM^*.

Sapropeļa kūdras, sapropeļa kokskaidu siltumizolācijas plāksnes un to īpašības
2014
Siltumizolācijas materiāli, kuros par pildvielu tiktu izmantoti vietējie biomasas produkti, bet par saistvielu kalpotu dabiskas izcelsmes saistvielas, piemēram, sapropelis, uzskatāmi par inovatīviem un to pielietošana sekmētu ekoloģiskās būvniecības nozares attīstību. Šādu risinājumu izstrāde ir aktuāla, jo Latvijā ir ievērojami sapropeļa resursi, kuru izmantošanu kavē to nepietiekama izpēte un ekoloģiskās būvniecības nozares intensīva attīstība. Pētījuma mērķis ir iegūt sapropeļa-koksnes, kūdras-koksnes siltumizolācijas plāksnes, noteikt optimālās plātnes sastāva attiecības un raksturot iegūto plātņu īpašības. Veikto pētījumu rezultātā tika noteiktas siltumizolācijas materiālu paraugu mehā…
Ecomusei e micromusei
2022
Faced with a renewed framework of museology, the concept of cultural heritage, expanding enormously, refers to a great complexity of underlying elements, stories and relationships that require and await a necessary narrative, conveyed by material and immaterial, communicative artifacts. Design is called, today more and more often, to operate within the complexity of design strategies that are able to develop new ways of enhancing, communicating and using cultural heritage and traditional productions rooted in the territories, exploring their multiple aspects also through methodologies of highly experimental design (interactive, multimedia). Each ecomuseum represents a unique reality, by ter…
Global Perspective on Marital Satisfaction
2020
Across the world, millions of couples get married each year. One of the strongest predictors of whether partners will remain in their relationship is their reported satisfaction. Marital satisfaction is commonly found to be a key predictor of both individual and relational well-being. Despite its importance in predicting relationship longevity, there are relatively few empirical research studies examining predictors of marital satisfaction outside of a Western context. To address this gap in the literature and complete the existing knowledge about global predictors of marital satisfaction, we used an open-access database of self-reported assessments of self-reported marital satisfaction wit…
Measuring the Economic, Environmental, and Social Sustainability of Short Food Supply Chains
2019
The production and distribution of food are among the hot topics debated in the context of sustainable development. Short food supply chains (SFSCs) are now widely believed to be more sustainable in comparison to mass food delivery systems. To date, very little quantitative evidence exists on the impacts of various types of food supply chains. Using a cross-sectional quantitative approach, this study assesses the sustainability of distribution channels in short and long food supply chains based on 208 food producers across seven countries: France, Hungary, Italy, Norway, Poland, the United Kingdom, and Vietnam. Ten distribution channel types are used in this study. To provide a comprehensiv…

Prepublicaciones: distribucion centralizada vs. descentralizada.
2000
Prepublications are accounts of research results that are distributed prior to formal publication in scientific journals. They are the form of scholarly communication that has taken more advantage of the advances in telecommunication and information technologies. Their electronic distribution has taken a different form within the disciplines. In this paper we compare the decentralized model of Economies with the centralized model of Physics.<br><br>Las Prepublicaciones, borradores de trabajos distribuídos antes de su publicacion formal en revistas, han sido el proceso de comunicación científica que más se ha beneficiado de los avances en telecomunicaciones. Su distribución elect…
Relación entre formación universitaria y competencia mediática del profesorado
2019
Este trabajo muestra el vínculo entre los niveles de competencia mediática del profesorado no universitario y la formación recibida por el profesorado de acuerdo con los actuales currículos universitarios en España. A partir de nuestro análisis, que se llevó a cabo a partir de los currículos de todas las universidades españolas con formación en educación (un total de 252 grados) y de un diagnóstico de competencia mediática de profesores no universitarios (906 sujetos) de nueve provincias españolas, llegamos a la conclusión de que existe una relación coherente entre estas dimensiones. En otras palabras, las deficiencias en la competencia mediática del personal docente no universitario son un…
Employers’ Needs and Expectations for Qualified Employees (Case Study on the Opinions in One of the Regions in Latvia)
2015
Abstract Qualified, loyal and motivated employees are highly demanded by employers and business promoters. The paper deals with employers’ needs and expectations for qualified and loyal employees, and investigates cooperation of employers, educators and municipalities. The following methods were used: analysis of scientific publications; focus group discussions; surveys of employers, teaching staff, students and graduates of VEI. For survey data analysis descriptive statistical analysis, non-parametric statistical test of Kruskal-Wallis and factor analysis were applied. The main findings indicate that besides professional skills and competence, social competence, motivation to work and resp…
