Institutional Autonomy and the Attractiveness of the European Higher Education Area – Facts or Tokenistic Discourse?

2012

In the discourse of the Bologna Process, the notion of competitiveness as the focal goal of Bologna Process, and university autonomy as one of its founding principles are consistently linked. Autonomy is framed as a precondition of competitiveness, while competitiveness is framed in terms of attractiveness of European higher education and higher education institutions. This paper examines their relationship, discussing whether there is ground for the repeated policy argument of their going hand in hand. Do the more attractive countries have higher autonomy, are the countries with higher autonomy more attractive? Or are these phenomena linked only in the simplified arguments of the policy di…

Multitasking in Driving as Optimal Adaptation Under Uncertainty

2021

Objective The objective was to better understand how people adapt multitasking behavior when circumstances in driving change and how safe versus unsafe behaviors emerge. Background Multitasking strategies in driving adapt to changes in the task environment, but the cognitive mechanisms of this adaptation are not well known. Missing is a unifying account to explain the joint contribution of task constraints, goals, cognitive capabilities, and beliefs about the driving environment. Method We model the driver’s decision to deploy visual attention as a stochastic sequential decision-making problem and propose hierarchical reinforcement learning as a computationally tractable solution to it. The…

Palvelukeskeisen arkkitehtuurin suunnittelumenetelmät

2009

  Alamaa, Jari Markus Palvelukeskeisen arkkitehtuurin suunnittelumenetelmät / Jari Alamaa Jyväskylä: Jyväskylän yliopisto, 2008, 42 s. Kandidaatintutkielma Nykypäivän nopeasti muuttuva liiketoiminnan tehtäväkenttä asettaa tietojärjestelmät uudenlaisien haasteiden eteen. Tietojärjestelmien vaatimustaso on noussut, ja järjestelmän joustavuudesta sekä tehokkuudesta on tullut merkittävä kilpailutekijä. Tilanteen ratkaisemiseksi on oman vastauksensa antanut palvelukeskeinen arkkitehtuuri, joka on teknologiariippumaton ajatusmalli arkkitehtuurin toteuttamiseen. Palvelukeskeinen arkkitehtuuri mahdollistaa tietojärjestelmän toimintojen ja vanhojen perinnejärjestelmien uudelleenkäytön sekä tietojärj…

Space of signatures as inverse limits of Carnot groups

2021

We formalize the notion of limit of an inverse system of metric spaces with 1-Lipschitz projections having unbounded fibers. The construction is applied to the sequence of free Carnot groups of fixed rank n and increasing step. In this case, the limit space is in correspondence with the space of signatures of rectifiable paths in ℝn, as introduced by Chen. Hambly-Lyons’s result on the uniqueness of signature implies that this space is a geodesic metric tree. As a particular consequence we deduce that every path in ℝn can be approximated by projections of some geodesics in some Carnot group of rank n, giving an evidence that the complexity of sub-Riemannian geodesics increases with the step.…

Cell fate specification in an in vitro model of neural development

1998

We have studied in an in vitro model of neural development the effect of neighboring cells on the fate of single fluorescently labeled precursor cells. In one line of experiments, PCC7-Mz1 embryonal carcinoma cells were transiently transfected with "green fluorescent protein" (GFP) and, following incubation with 0.1 microM all-trans retinoic acid (RA), the number and morphology of derivatives (neuronal or non-neuronal) was determined that form groups of GFP-expressing cells in a surrounding of unlabeled cells. Because single PCC7-Mz1 cells can produce single-lineage and mixed-lineage derivatives, they are individually pluripotent. In another line of experiments, we have analyzed the fate of…

"Quels beste ce pooit estre" : Merlin et le bestiaire dans trois Suites du Merlin en prose : d'une poétique du personnage à une poétique du roman

2016

One of the most eminent figures of Arthurian literature, renowned in the Middle Ages as in later periods, Merlin remains however a polymorphous and contradictory character. A study focusing on two aspects will allow us to perceive his ambiguities and to form the poetics of the character. Firstly, from a relational perspective, the bestiary, that is to say the literary fauna, constitutes an element of this definition. In Prose Merlin’s retrospective prose sequels (the “Vulgate” Suite, the “Post-Vulgate” Suite and the Livre d’Artus), romances which constitute the apex of thirteenth century Arthurian texts in prose, this relation axis encounters an intertextual perspective. By its extent and i…

Chlorophyll Concentration Retrieval by Training Convolutional Neural Network for Stochastic Model of Leaf Optical Properties (SLOP) Inversion

2020

Miniaturized hyperspectral imaging techniques have developed rapidly in recent years and have become widely available for different applications. Combining calibrated hyperspectral imagery with inverse physically based reflectance models is an interesting approach for estimating chlorophyll concentrations that are good indicators of vegetation health. The objective of this study was to develop a novel approach for retrieving chlorophyll a and b values from remotely sensed data by inverting the stochastic model of leaf optical properties using a one-dimensional convolutional neural network. The inversion results and retrieved values are validated in two ways: A classical machine learning val…
