Quel statut pour les espaces de montagne durant l'âge du Bronze ? Regards croisés sur les approches société-environnement dans les Pyrénées occidenta…
2005
After having been neglected for some time, mountain environments have now become an important research area for the study of anthropogenic impact on the environment and the interactions of societies with their environments. The recent development of several interdisciplinary programs in the Alps and in the Pyrenees reveals the interest and the scientific questions associated with these domains. In the Pyrenees, the work undertaken in the Basque Country illustrates the utility of the development of multidisciplinary research on a large scale, which is both diachronic and has a high resolution chronology. Combining environmental and archaeological data, allows us to present an image of popula…
Differentiation among dairy products by combination of fast field cycling NMR relaxometry data and chemometrics
2021
A set of commercial milk and Sicilian cheeses was analysed by a combination of fast field cycling (FFC) nuclear magnetic resonance (NMR) relaxometry and chemometrics. The NMR dispersion (NMRD) curves were successfully analysed with a mathematical model applied on Parmigiano-Reggiano (PR) cheese. Regression parameters were led back to the molecular components of cheeses (water trapped in casein micelles, proteins and fats) and milk samples (water belonging to hydration shells around dispersed colloidal particles of different sizes and bulk water). The application of chemometric analysis on relaxometric data enabled differentiating milk from cheeses and revealing differences within the two sa…
Mitochondrial function and sirtuin expression in hippocampus of young and old high- and low-capacity runner rats
2016
Introduction: Exercise and aerobic capacity are associated with improved learning in animals and humans. The hippocampus is a brain structure involved in learning and memory. High rates of neurogenesis have been shown to take place in the dental gyrus of hippocampus in response to physical exercise. It is not known whether mitochondrial dysfunction in the hippocampus is responsible for decline in cognitive function associated with low fitness level and aging, and whether intrinsic aerobic capacity is a risk factor for it. Methods: Mitochondrial function was investigated in the hippocampi of young and old highcapacity runner (HCR) and low-capacity runner (LCR) rats using high-performance res…
A Bayesian Mixed-Methods Analysis of Basic Psychological Needs Satisfaction through Outdoor Learning and Its Influence on Motivational Behavior in Sc…
2017
Research has shown that outdoor educational interventions can lead to students' increased self-regulated motivational behavior. In this study, we searched into the satisfaction of basic psychological needs (BPN), i.e., autonomy support, the learners' experience of competence, and relatedness, both within the peer group and with their teachers, through outdoor learning. From 2014 to 2016, n = 281 students attended “research weeks” at a Student Science Lab in the Alpine National Park Berchtesgaden (Germany). The program is a curriculum-based one-week residential course, centered on a 2-day research expedition. Both before and after the course, students completed a composite questionnaire addr…
A magnetic look into the protecting layer of Au25 clusters
2016
The field of molecular metal clusters protected by organothiolates is experiencing a very rapid growth. So far, however, a clear understanding of the fine interactions between the cluster core and the capping monolayer has remained elusive, despite the importance of the latter in interfacing the former to the surrounding medium. Here, we describe a very sensitive methodology that enables comprehensive assessment of these interactions. Pulse electron nuclear double resonance (ENDOR) was employed to study the interaction of the unpaired electron with the protons of the alkanethiolate ligands in four structurally related paramagnetic Au25(SR)0 18 clusters (R ¼ ethyl, propyl, butyl, 2-methylpro…
Complete 1H, 13C{1H}, and 31P NMR Spectral Parameters of Some Pyrophosphates
2017
The 1H, 13C{1H}, and 31P NMR spectral parameters of some pyrophosphates were determined in CDCl3. The most complicated 1H spectrum can be solved fully only as (A3MN)R6XX′R6′(MNA3)′, where R6 (= ―N(CH3)2) is coupled only to phosphorus (X). Second-order coupling between phosphorus was found and solved with iterative analysis. A signal shape of one of the carbon resonance cannot be explained only with couplings. Explanation for exceptional shape was searched from molecular modeling results. peerReviewed
Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory
2017
We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to $80^\circ$ and energies in excess of 4 EeV ($4 \times 10^{18}$ eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional informa…
Diversity management and intercultural communication experiences in multicultural organisations in South Ostrobothnia
2014
Tämän kvalitatiivisen tutkimuksen tarkoituksena on selvittää millaisia kokemuksia eteläpohjalaisilla johtajilla on monimuotoisuuden johtamisesta ja kulttuurienvälisestä viestinnästä monikulttuurisissa organisaatioissa. Työn teoriaosuudessa käsitellään kulttuurienvälisen viestinnän ja monimuotoisuuden johtamisen teoriaa sekä monikulttuurisuutta ja työperäistä maahanmuuttoa Suomessa ja Etelä-Pohjanmaalla. Empiirinen tutkimusaineisto kerättiin teemahaastattelujen avulla. 11 johtajaa haastateltiin ja analysointimenetelmänä käytettiin teemoittelua. Tutkimuksen merkittävimpiä tuloksia oli, että yritykset ovat rekrytoineet työvoimaa ulkomailta pääasiassa, koska yritykset eivät ole löytäneet osaava…
Trust and team identification at multicultural workplaces : perceptions of Finnish HR professionals
2017
Growing global mobility has rapidly diversified workplace demographics across the world. Finland that has traditionally been considered a relatively uniform nation in terms of cultural and ethnic diversity has also experienced a shift in its population in recent decades. Despite the growing multiculturalism, established diversity management practices are yet to be developed in many Finnish organizations, and the subject has not gained much academic attention either. Still, competent intercultural leaders are often vital for both successful business results and for the well-being of their multicultural teams. The aim of this thesis is to shed light on the current state of international human…
Placer y felicidad en los moralistas franceses de finales del siglo XVII y comienzos del siglo XVIII
2023
A finales del siglo XVII y comienzos del siglo XVIII en Francia los aspectos terrenales del placer no tenían cabida en una moral eminentemente cristiana. Los autores que se estudian en esta tesis se alejan de los moralistas clásicos, pues ni pretenden sentar cátedra ni diseccionar la antropología de un ciudadano que ya deja de ser negativa. También se distancian de los libertinos que les seguirán, más próximos a la ficción prerromántica y al sensualismo desprovisto de metafísica. El contexto histórico-social es de interés al profundizar en la aparición de la 'société précieuse' , que se articula en torno a los salones y a los cafés; instituciones donde la mujer gozaría de un papel activo. E…
