Reactivity of the Superheavy Element 115, Mc, and Its Lighter Homologue, Bi, with Respect to Gold and Hydroxylated Quartz Surfaces from Periodic Rela…
2021
Adsorption energies (Eads) of the superheavy element (SHE) Mc, its lighter homologue (Bi), as well as of another superheavy element Nh and some lighter homologues of SHEs on gold and hydroxylated quartz surfaces are predicted via periodic relativistic density functional theory calculations. The aim of this study is to support "one-atom-at-a-time" gas-phase chromatography experiments that are examining the reactivity and volatility of Mc. The obtained Eads values of the Bi and Mc atoms on the Au(111) surface are >200 kJ/mol. On the hydroxylated quartz surface, Mc should adsorb with a minimal energy of 58 kJ/mol. On both types of surfaces, Eads(Mc) should be ∼100 kJ/mol smaller than Eads(Bi) …
1H-naphtho[2,1-b]thiete and 2H-naphtho[2,3-b]thiete- synthesis and reactivity
1994
Abstract The title compounds 4 and 8 are obtained by flash vacuum pyrolysis of the corresponding hydroxymethylthionaphthols 3 and 7. Whereas 4 shows a smooth ring opening on heating, 8 is thermally stable but reacts photochemically. The different behavior is explained on the basis of an MNDO calculation. The valence isomers 4′ and 8′ represent thioquinonemethides, which are highly reactive components in [12π + 2π]cycloaddition processes (4 → 9, 10, 11; 8 → 12).

Moral values, empathy and identification with fictional characters: the representative universe at “Cuéntame cómo pasó” (TVE)
2012
En la presente investigación se muestran los resultados de un estudio de base experimental sobre el análisis de los valores morales presentes en la serie emitida por Televisión Española “Cuéntame cómo pasó”. La discusión se centra en los valores morales como el aspecto nuclear de este constructo audiovisual, en especial en su posible correlación con la identificación de los personajes y la empatía ficcional del formato. En el estudio participaron 47 estudiantes universitarios y 36 personas de más edad, quienes fueron sometidos a unos cuestionarios analíticos anteriores y posteriores al visionado de dos capítulos de la serie televisiva. Tras la aplicación pre-test y post-test de la Escala de…
Economic performance in Spanish sports clubs: entrepreneurial orientation of professional and non-professional teams analysed through fsQCA
2021
Sports clubs play an important role in the creation of social value, however, despite the scarcity of studies, analysing the associative sports environment from an economic perspective has an undeniable relevance. The entrepreneurial orientation (EO) has been largely related to the economic performance of the organisation, however, this study has found a difference in sports clubs related to their legal and organisational structure. The analysed sample is composed of 13 non-professional sports clubs and 13 professional sports clubs, using the fsQCA methodology. According to the results obtained, EO has an influence on the economic performance (EP) of sports clubs, with proactivity being the…
The Value of Media in the Acquisition of Master Degree Program: Students’ Assessment
2015
Rapid development of innovative processes characterizes the conditions of the scientific and technical revolution. The understanding about the place and role of the man in the innovative society also changes. Therefore the readiness of the social and individual consciousness to changes in all spheres of life (including education) and the acceptance of the novelties as a value are important. It testifies about a new orientation of education which applies to methods as well as their forms, content and aim. But is the preschool teacher ready to use media in her professional work? Does the acquisition of higher education promote it? The aim of the article is to study the use of the innovative t…
A SELECTION OF METHODS AND TECHNIQUES PROFESSIONAL TEACHERS CAN APPLY TO THEIR OWN LIFELONG LEARNING
2018
A selection of methods and techniques professional teachers can apply to their own lifelong learning.Education is the key to converting knowledge and experience into practical actions, their analysis and application. It plays a key role in the synthesis of new knowledge into research and innovation. Such thoughts on education were expressed in the resolution of the sixth World Education Congress in 2011. Today, when world education forums are widely discussing how schools can better organise the learning process, when ambitious long-term reforms are being implemented in the Latvian education system—the transition to competency-based educational content and teaching methods—it is essential t…
Sports clubs as settings for health promotion: fundamentals and an overview to research.
2014
This paper explores the efficacy and value of sports clubs as a setting for health promotion. Sports clubs for children and adolescents are the primary focus of the paper, and the aims are two-fold. Aims: Firstly, the paper aims to review the basis for and elements of the health promoting sports club (HPSC) concept. Secondly, the aim is to overview the international evolution of the HPSC concept and its usefulness in the research. The settings-based health promotion approach forms the basis for the HPSC concept and it is introduced first. Thereafter, both obligating and prospecting factors, to justify the importance for sports clubs to address health promotion, are expressed. Major prospec…
Analyzing Consumer Engagement Programs from the Perspective of a Qualitative Research of Marketing Executives
2014
Abstract Consumer engagement is a multidimensional concept comprising cognitive, emotional, and/or behavioral dimensions, and plays a central role in the process of developing long lasting relationships with mutual benefits for companies and their customers. In the Internet-context, consumers can co-create experiences and personal value through engagement in activities that involve interactivity and networking with companies in the online environment. In this technology-driven framework, consumer engagement programs can offer a valuable opportunities for companies that are active in an online setting. The present research implies a qualitative study conducted using interviews with marketing…
Children's expectancy beliefs and subjective task values through two years of school-based program and associated links to physical education enjoyme…
2016
Purpose: The present study examined the patterns of children's expectancy beliefs and subjective task values through the Physical Activity as Civil Skill Program and associated links to physical education enjoyment and total physical activity. Methods: The sample comprised 401 children aged 9–13 years from 3 small towns located in North-East Finland. All children received school-based activities across 2-year program from Grades 5 to 7. The present data were collected using questionnaires across 3 measurement phases during 2012–2014. Results: The levels of expectancy beliefs and subjective task values indicated to be relatively high and the development was stable through the program, especi…
