Hölder regularity for stochastic processes with bounded and measurable increments
2022
We obtain an asymptotic Hölder estimate for expectations of a quite general class of discrete stochastic processes. Such expectations can also be described as solutions to a dynamic programming principle or as solutions to discretized PDEs. The result, which is also generalized to functions satisfying Pucci-type inequalities for discrete extremal operators, is a counterpart to the Krylov-Safonov regularity result in PDEs. However, the discrete step size $\varepsilon$ has some crucial effects compared to the PDE setting. The proof combines analytic and probabilistic arguments.
Predicting Individual Differences from Brain Responses to Music using Functional Network Centrality
2022
Individual differences are known to modulate brain responses to music. Recent neuroscience research suggests that each individual has unique and fundamentally stable functional brain connections irrespective of the task they perform. 77 participants’ functional Magnetic Resonance Imaging (fMRI) responses were measured while continuously listening to music. Using a graph-theory-based approach, we modeled whole-brain functional connectivity. We then calculate voxel-wise eigenvector centrality and subsequently use it to classify gender and musical expertise using binary Support Vector Machine (SVM). We achieved a cross-validated classification accuracy of 97% and 96% for gender and musical exp…
Second Language Prosody and its Development : Connection between Different Aspects
2018
This study focuses on the development of L2 prosody and, in particular, whether different aspects can affect each other. Finnish-speaking learners of Swedish took part in a pronunciation and oral skills course and were recorded for various speaking tasks before and after the experimental intervention. Read-aloud declarative sentences (statements) from nine learners were acoustically analysed for several tonal and temporal aspects, focusing on the marking of primary stress. The results reveal that the learning of Swedish tonal word accent 2 (H*LH) facilitates other tonal developments towards native-like utterance intonation. A link between tonal and temporal developments in the marking of pr…
Migrants at the university doorstep : How we unfairly deny access and what we could (should) do now
2022
The Finnish Government recently launched policies to meet labor shortage challenges, recruit highly skilled international workers. However, they overlook a skilled population already living in Finland, namely highly educated migrants. The problem is that migrants tend to be treated similarly, whether they are well-educated or not. This means that migrants are typically directed into low paying jobs. How is it possible to better develop this group with more effective career guidance? We believe an important answer lies in improved university education for migrants. This investigation is based on responses from surveys, interviews, and project evaluations. An analysis is made of three success…
Tanatologičeskaâ problematika v povesti "Zlaâ večnostʹ" Georgiâ Peskova
2018
Pod pseudonimem Gieorgij Pieskow ukrywała się Elena Dejsza, przedstawicielka „młodszego pokolenia” pisarzy pierwszej fali emigracji rosyjskiej, autorka opowieści Zła wieczność (1932). W utworze istotne miejsce zajmuje problematyka tanatologiczna. Rozpatrywana jest ona w różnych aspektach: poruszany jest tu problem samobójstwa, odbieranego jako zwycięstwo nad śmiercią; sporo miejsca poświęca się immortologii — bibliotekarz ma obsesję na punkcie nieśmiertelności; zwraca się także uwagę na starzenie się jako zjawisko towarzyszące umieraniu; dokonuje się też zabójstwa. W sferze ideowo-tematycznej poruszany jest problem zagłady cywilizacji europejskiej. Na tanatologię artystyczną Gieorgija Piesk…
Momentum-space structure of surface states in a topological semimetal with a nexus point of Dirac lines
2016
Three-dimensional topological semimetals come in different variants, either containing Weyl points or Dirac lines. Here we describe a more complicated momentum-space topological defect where several separate Dirac lines connect with each other, forming a momentum-space equivalent of the real-space nexus considered before for helium-3. Close to the nexus the Dirac lines exhibit a transition from type I to type II lines. We consider a general model of stacked honeycomb lattices with the symmetry of Bernal (AB) stacked graphite and show that the structural mirror symmetries in such systems protect the presence of the Dirac lines, and also naturally lead to the formation of the nexus. By the bu…
Place Names along the Júcar/Xúquer River in the Land of València
2012
Tras abandonar la Mancha el Júcar entra en el País Valenciano y a partir de su confluencia con el Cabriel, discurre primero encajado entre gargantas y luego sobre el llano aluvial de la Ribera, donde se le llama Xúquer. A ambos lados del río encontramos una toponimia –muchas veces poco transparente– que deriva de las características físicas de este río, de la protección ante sus avenidas, o de la vigilancia de los pasos o los caminos que lo atraviesan. Así pues, no sólo se trata de hidrónimos, sino también de odónimos, orónimos y toponimia de carácter defensivo. La metodología que hemos seguido parte del Nomenclàtor Toponímic de la Comunitat Valenciana, que cuenta con más de 100.000 topónim…
¿Por qué Turismo? Repensar el auge del turismo
2017
In the present work we consider the reasons that explain the spectacular tourism boom in the last 5 decades. The traditional responses to this phenomenon, presented a whole "frond" of tourist-economical interactions: tourism as a "motor of development", tourism as "dynamizing the economic system", etc. Therefore, our objective is to contrast this Tourism-Development-Economic Growth framework, certainly suggestive. In order to avoid mystifications it is necessary to define somewhat ambiguous concepts such as Development (and its interactions with Tourism) and to deepen the economic impact of Tourism, the ultimate root of all that "frond" that seems to be the basis of This formidable theoreti…
La marque ou une mention innovante permet-elle de compenser l'impossibilité de toucher le produit par les consommateurs ?
2015
Packaging or methods of distance selling prevent consumers from touching the products and therefore from evaluating them properly. Thus the aim of this research is to observe whether extrinsic information, such as brand or innovative cue, can compensate this lack of sensory information and so improve the hedonic evaluation. An experiment conducted on 110 subjects with two fabrics shows that consumers evaluate them more positively when they observe them with an extrinsic information than when they observe them without this information, and that this improvement is greater than that obtained when we allow them to assess the fabrics by the touch in addition to the mere sight.
Can globalization be socially inclusive through tourism 2.0?
2015
International audience; Can globalization be socially inclusive through new 2.0 digital initiatives? This is the thought-provoking question we ask in this article, with a special focus on the Republic of Moldova. Part 1 begins with a reflection on the intersection between globalization, development studies and the current Moldovan context. Part 2 is devoted to the promising field of emergent tourism, and more particularly, tourism 2.0, a blossoming concept that we try to uncover. Part 3 presents a concrete application with the example of Moldova Tours 2.0, a new digital initiative in the field of e-tourism. Finally, we conclude.
