Teachers' self-efficacy and the sources of efficacy: A cross-cultural investigation in Japan and Finland

2019

The study explores the extent and sources of Teachers’ Self-Efficacy (TSE) for inclusive practices among 261 Japanese and 1123 Finnish teachers. Measurement invariance was tested to ensure the chosen scales’ cross-cultural validity. In both countries, mastery experience was identified as the strongest of the four sources contributing uniquely to TSE. However, the two groups differed in how verbal persuasion predicted TSE. The findings indicate that the effects of the four sources on TSE depend strongly on sociocultural context, and that, in Japan, other sources may exert a powerful influence. Practical implications are discussed, with particular regard to teacher training programs. peerRevi…

Differences in children's school success and family backgrounds : a comparative case study of pupils' performance in entrance examination in Ibadan, …

2013

This study reviewed the socio-economic backgrounds of pupils from various family structures (Monogamous, polygamous, single-parent and orphan children) against their academic performances in Ibadan North-East municipality of Ibadan, Nigeria. The diverse contending studies on how the socio-economic backgrounds of these family structures aid children’s academic attainments were examined. The data for this study was gathered in April, 2012. The study employed both qualitative and quantitative data collection method. A total of two hundred and twenty pupils between the ages of 10 to15 in junior secondary schools were sampled, N=220 and 8 teachers were interviewed from the various pupils’ school…

Biélorussie : Loukachenko forever? : Petit-déjeuner en ligne de l’Observatoire des Etats Post-Soviétiques

2021

Fonds audiovisuel de l'Inalco, France, © 2021; Plus d'une année s'est écoulée depuis le début des mouvements d'opposition de masse en Biélorussie. Vacillant il y a encore quelques mois, le régime de Loukachenko est cependant toujours en place. Où en est la révolution biélorusse aujourd'hui ? Quelle stratégie déploie le régime et quelles sont les perspectives de l'opposition ? Quelles sont enfin les dimensions géopolitiques de la politique intérieure biélorusse ? Nous ferons le point avec nos invités Ronan Hervouet et Alexandra Goujon.

Wewnętrzne podziały i opozycja wewnątrzpartyjna w Socjaldemokratycznej Partii Niemiec w drugiej połowie XX wieku

2016

The Social Democratic Party of Germany was (and still is) a political party, in which the existence of different informal groups and clubs (performing the function of the Opposition inside the party) is admissible. After the end of the war and the return of the SPD to a legał activity, there followed - within it - a revival of not only old structures, but also that of old divisions into the leit wing and the right wing, which referred to the ideas of revisionism and questions of reforms capable of changing or maintaining the capitalist political system. With time, there formed two main wings among the democrats: the right wing - known as Kanalarbeiter, and later on Seeheimer Kreis, and the …

Structural and optical characterization of ZnS ultrathin films prepared by low-temperature ALD from diethylzinc and 1.5-pentanedithiol after various …

2019

The structural and optical evolution of the ZnS thin films prepared by atomic layer deposition (ALD) from the diethylzinc (DEZ) and 1,5-pentanedithiol (PDT) as zinc and sulfur precursors was studied. A deposited ZnS layer (of about 60 nm) is amorphous, with a significant S excess. After annealing, the stoichiometry improved for annealing temperatures &ge

Evolution of microstructure and related optical properties of ZnO grown by atomic layer deposition.

2013

A study of transmittance and photoluminescence spectra on the growth of oxygen-rich ultra-thin ZnO films prepared by atomic layer deposition is reported. The structural transition from an amorphous to a polycrystalline state is observed upon increasing the thickness. The unusual behavior of the energy gap with thickness reflected by optical properties is attributed to the improvement of the crystalline structure resulting from a decreasing concentration of point defects at the growth of grains. The spectra of UV and visible photoluminescence emissions correspond to transitions near the band-edge and defect-related transitions. Additional emissions were observed from band-tail states near th…

Optical and structural properties of Al 2 O 3 /ZnO nanolaminates deposited by ALD method

2014

International audience; We report on the investigation of optical and structural properties of Al2O3/ZnO nanolaminates. The nanolaminates were deposited on Si and glass substrates by Atomic layer deposition method. Structural properties of nanolaminates were studied by SEM, GIXRD, and AFM. Optical characterization was performed by transmittance and photoluminescence spectroscopy. Complex analysis of monolayer properties was done by ellipsometry. Optical constants for Al2O3 and ZnO monolayer were calculated.

Atomic layer deposition of AlN from AlCl3 using NH3 and Ar/NH3 plasma

2018

The atomic layer deposition (ALD) of AlN from AlCl3 was investigated using a thermal process with NH3 and a plasma-enhanced (PE)ALD process with Ar/NH3 plasma. The growth was limited in the thermal process by the low reactivity of NH3, and impractically long pulses were required to reach saturation. Despite the plasma activation, the growth per cycle in the PEALD process was lower than that in the thermal process (0.4A ° vs 0.7A ° ). However, the plasma process resulted in a lower concentration of impurities in the films compared to the thermal process. Both the thermal and plasma processes yielded crystalline films; however, the degree of crystallinity was higher in the plasma process. The…
