Auditory cortical and hippocampal-system mismatch responses to duration deviants in urethane-anesthetized rats

2013

Any change in the invariant aspects of the auditory environment is of potential importance. The human brain preattentively or automatically detects such changes. The mismatch negativity (MMN) of event-related potentials (ERPs) reflects this initial stage of auditory change detection. The origin of MMN is held to be cortical. The hippocampus is associated with a later generated P3a of ERPs reflecting involuntarily attention switches towards auditory changes that are high in magnitude. The evidence for this cortico-hippocampal dichotomy is scarce, however. To shed further light on this issue, auditory cortical and hippocampal-system (CA1, dentate gyrus, subiculum) local-field potentials were …

Labor market matching with application to Finnish data

2014

This thesis studies labor market matching and takes use of a matching function, which describes the technology how unemployed job seekers and vacant jobs search, meet and form new employment relationships. The goal of the study is twofold: First is to provide a comprehensive critical review of previous literature covering both micro models as well as empirical applications. Major limitations in empirical studies are imperfect measures of variables as well as inability to account for all relevant factors making results methodology-sensitive. The second contribution is to estimate a matching function for Finland using annual data from 2006-2012 and thus giving the most recent knowledge on the…

Stability of stochastic nonlinear systems with state-dependent switching

2013

In this paper, the problem of stability on stochastic systems with state-dependent switching is investigated. To analyze properties of the switched system by means of Itô’s formula and Dynkin’s formula, it is critical to show switching instants being stopping times. When the given active-region set can be replaced by its interior, the local solution of the switched system is constructed by defining a series of stopping times as switching instants, and the criteria on global existence and stability of solution are presented by Lyapunov approach. For the case where the active-region set can not be replaced by its interior, the switched systems do not necessarily have solutions, thereby quasi-…

Impact of supplier-specific investments in inter-organisational information systems on strategic electronic coordination: the moderation effect of bu…

2018

Abstract This paper examines the factors which influence sharing of the strategic information (in other words, electronic coordination) in a buyer–supplier dyad. The antecedents of this coordination are examined rather well in the transaction cost economics (TCE) theory and resource-dependency theory (RDT), while the supply chain management perspective is contemplated. The mentioned frameworks are used in the analysis. However, the research focus is narrowed down to the exploration of the antecedents of information exchange conducted via inter-organisational information systems (IOS). The empirical analysis is based on 198 observations of Norwegian companies operating in different types of …

Information transmission under an experimental approach

2015

Nueva evidencia sobre la eficiencia del mercado español de futuros sobre acciones. El objetivo de este primer capítulo es presentar nueva evidencia sobre la eficiencia del mercado español de futuros sobre acciones durante el período 2001-2010. Para ello, nos servimos del análisis de correlación realizado sobre carteras índices igualmente ponderadas y ponderadas por volumen, así también sobre contratos de futuros individuales. Este análisis revela la existencia de autocorrelación negativa en el corto plazo de una semana. Para explotar el beneficio del arbitraje procedente del patrón de fuente temporal, construimos un conjunto de estrategias de negociación á la Conrad and Kaul para cada día d…

Voimaharjoittelun vaikutukset dynaamiseen ja staattiseen tasapainoon nuorilla ja ikääntyneillä

2017

Tasapainolle ei ole olemassa universaalia määritelmää mutta se tiedetään, että sitä kontrolloivat useat eri mekanismit. Ikääntyminen aiheuttaa siinä heikkenemistä, joka aiheutuu muutoksista sekä sensorisissa että motorisissa prosesseissa. Kaatumisesta aiheutuneiden vammojen määrä kasvaa koko ajan ikääntyneillä. Heidän onkin havaittu pärjäävän nuoria huonommin sekä staattisissa että dynaamisissa testeissä mutta dynaamisissa testeissä ero on vieläkin suurempi. Erityisesti dynaamisten ominaisuuksin tutkiminen on tärkeää sillä staattiset testit eivät välttämättä paljasta tasapaino-ongelmia tai ikääntymiseen liittyviä eroja yhtä hyvin kuin dynaamiset testit. Tämän tutkimuksen suoritti loppuun 4 …

Modulations of corticospinal excitability following rapid ankle dorsiflexion in skill- and endurance-trained athletes

2022

Abstract Purpose Long-term sports training, such as skill and endurance training, leads to specific neuroplasticity. However, it remains unclear if muscle stretch-induced proprioceptive feedback influences corticospinal facilitation/inhibition differently between skill- and endurance-trained athletes. This study investigated modulation of corticospinal excitability following rapid ankle dorsiflexion between well-trained skill and endurance athletes. Methods Ten skill- and ten endurance-trained athletes participated in the study. Corticospinal excitability was tested by single- and paired-pulse transcranial magnetic stimulations (TMS) at three different latencies following passive rapid ankl…
