Finland: Changing Operational Environment Changing Finnish Educational Governance
2020
The main purpose of this chapter is to examine how Finland is developing its educational governance to meet the challenges of its changing operational environment. For our examination, we applied two theoretical frameworks on education policy development. The one constructed in the Comparative Analysis of Dynamics in Education Politics Project (CADEP) by Simola, Kauko, Varjo, Kalalahti and Sahlstrom (Dynamics in education politics. Understanding and explaining the Finnish case. Routledge, Oxon and New York, 2017) provided us with the theoretical lenses of political situations, political possibilities and politicking, as well as with valuable contextual information. The one for the Policy En…
INFLUENCE OF INTEREST GROUPS IN LATVIA ON CENTRALIZATION
2021
Latvia has experienced four administrative-territorial reforms in 30 years. In 1989, local and regional elections were the first democratic elections in Latvia since 1934. From 1990 to 1992, self-governments were the main authority for re-establishing national independence and transforming the country from totalitarianism to democracy. The transformation process starts with wide decentralization, including substantial fiscal decentralization and substantial administrative decentralization.
 The first reform was the centralization (1994) of Rīga city government (1 self-government instead of a two-tier system, with 6 district local governments and 1 city local government). The second re…
On the factors governing the pressure dependence of the viscosity of moderately concentrated polymer solutions
1982
Viscosity measurements were carried out as a function of pressure and temperature with solutions of polystyrene in eight (endothermal) θ-solvents at the respective critical composition by means of a Searle-type apparatus. A rolling-ball viscometer was used for the investigation of the pure solvents. In all cases the viscosity coefficient increases in a more or less exponential manner when the pressure is raised. For θ-conditions, the volumes of activation of the solutions exceed that of the pure solvent by typically 10–15%. The exact amount of this extra efffect stemming from the presence of the polymer and its variation with temperature can be qualitatively correlated with the heats of mix…
Territorial defense, territory size, and population regulation.
2005
The carrying capacity of an environment is determined partly by how individuals compete over the available resources. To territorial animals, space is an important resource, leading to conflict over its use. We build a model where the carrying capacity for an organism in a given environment results from the evolution of territorial defense effort and the consequent space use. The same evolutionary process can yield two completely different modes of population regulation. Density dependence arises through expanding and shrinking territories if fecundity is low, breeding success increases gradually with territory size, and/or defense is cheap. By contrast, when fecundity is high, breeding suc…
Use of a running coupling in the NLO calculation of forward hadron production
2018
We address and solve a puzzle raised by a recent calculation [1] of the cross-section for particle production in proton-nucleus collisions to next-to-leading order: the numerical results show an un- reasonably large dependence upon the choice of a prescription for the QCD running coupling, which spoils the predictive power of the calculation. Specifically, the results obtained with a prescription formulated in the transverse coordinate space differ by one to two orders of magnitude from those obtained with a prescription in momentum space. We show that this discrepancy is an artefact of the interplay between the asymptotic freedom of QCD and the Fourier transform from coordinate space to mo…
¡Qué quejicosos! Buzón de quejas a través del aprendizaje cooperativo
2017
Resumen: En este artículo se ofrece una experiencia práctica enmarcada dentro del aprendizaje cooperativo, que crea una interdependencia positiva propicia para el aprendizaje. Para ello, después de una breve aproximación teórica al aprendizaje cooperativo, la argumentación y los actos de habla de queja, así como del género textual «carta de reclamación», se expone la propuesta de nivel B2 organizada en diferentes pasos: la selección de equipos, el análisis de cartas de reclamación, la modificación de los equipos, la asignación de roles, así como la escritura de cartas y posterior evaluación. Se trabajan distintas destrezas, además de conseguir que los alumnos interactúen como en la vida rea…
La dérive pédagogique parallèle. Un fil éducatif invisible entre Porto et Paris à travers des récits personnels
2019
Partimos de la deriva como práctica artística contemporánea, con reconocidos antecedentes históricos. El objetivo principal es experimentar las potencialidades pedagógicas de la observación de entornos urbanos de forma colaborativa y mediada por las TIC a través de la deriva, como artistas/investigadores/docentes encargados de la formación del profesorado, para poder introducir este tipo de iniciativas en el entorno educativo. La A/R/Tografía como método de Investigación Basada en las Artes facilita usar la deriva simultáneamente como práctica artística, proceso investigador y experiencia de aprendizaje docente. Los resultados se exponen a través de narrativas personales que muestran reflex…
Strong enhancement of superconductivity at high pressures within the charge-density-wave states of2H−TaS2and2H−TaSe2
2016
We present measurements of the superconducting and charge density wave critical temperatures (Tc and TCDW) as a function of pressure in the transition metal dichalchogenides 2H-TaSe2 and 2H-TaS2. Resistance and susceptibility measurements show that Tc increases from temperatures below 1 K up to 8.5 K at 9.5 GPa in 2H-TaS2 and 8.2 K at 23 GPa in 2H-TaSe2. We observe a kink in the pressure dependence of TCDW at about 4 GPa that we attribute to the lock-in transition from incommensurate CDW to commensurate CDW. Above this pressure, the commensurate TCDW slowly decreases coexisting with superconductivity within our full pressure range.
1976
The phenomenon of “true cosolvency”, which has only recently been observed in the system acetone/diethyl ether/polystyrene (AC/DEE/PS), is investigated with regard to its pressure dependence and compared with the thermodynamic behaviour of the corresponding binary sub-systems. For the determination of the limits of complete solubility, a pressure apparatus was used which had been constructed, in order to measure the turbidity of fluids in the temperature range of −70 to +500°Cand in the pressure range of 1 to 4000 bar (105 to 4·108 Nm−2). The critical line observed for the system DEE/PS (MPS=20400) looks similar to that reported for AC/PS in the literature, i.e. the upper critical solution …
