Abstract:

In Indonesia, the achievement standards for learning Arabic in Maharah Al-Kitabah are core competencies and basic competencies in each sub- and sub-sab in the teaching materials used, while in international forums the reference used is the Common European Framework of Reference for Language (CEFR). Competency standards are divided into several levels and can be modified according to the level of ability of students. In addition, the CEFR is also equipped with an assessment instrument to measure the development of students' abilities in all language skills, namely maharah istima', kalam, qiroah

Abstract:

Přechod na distanční výuku znovu otevřel otázku metodiky výuky cizích jazyků. Zimní semestr 2020/21 proběhl celý on-line, což se stalo výzvou zejména pro studenty prvních ročníků, kteří museli zvládnout přechod na zcela jinou formu studia, aniž by se mohli osobně seznámit s vysokoškolským prostředím. Vedení Matematicko-fyzikální fakulty se vzhledem k situaci na jaře 2020 rozhodlo přijmout všechny zájemce o studium bez přijímacích zkoušek, což do prvního ročníku přivedlo české i zahraniční studenty se značnými rozdíly ve znalosti angličtiny.

Abstract:

The Common European Framework of Reference for Languages (CEFR, Council of Europe, 2001) currently functions as an instrument for educational policy and practice. The view of language proficiency on which it is based and the six proficiency levels it defines lack empirical support from language-use data. Several issues need to be investigated collaboratively by researchers working in the fields of first and second language acquisition, corpus linguistics and language assessment. These issues are concerned with (i) the CEFR’s failure to consistently distinguish between levels of language profic

Abstract:

An increase in the level of active, GTP-bound Ras is not necessary for transformation of chicken embryo fibroblasts (CEF) by v-Src. This suggests that other Ras-independent pathways contribute to transformation by v-Src. To address the possibility that activation of phosphatidylinositol-3-kinase (PI3K) and the mammalian target of rapamycin (mTOR/FRAP), represents one of these pathways, we have examined the effect of simultaneous inhibition of the Ras-MAPK and PI3K-mTOR pathways on transformation of CEF by v-Src. Transformation was assessed by the standard parameters of morphological alteration

ABSTRACT v-Crk, an oncogene product of avian sarcoma virus CT10, efficiently transforms chicken embryo fibroblasts (CEF). We have recently reported that constitutive activation of the phosphoinositide 3-kinase (PI3K)/AKT pathway plays a critical role in the v-Crk-induced transformation of CEF. In the present study we investigated the molecular mechanism by which v-Crk activates the PI3K/AKT pathway. First, we found that v-Crk promotes the association of the p85 regulatory subunit of PI3K with focal adhesion kinase (FAK) by inducing the phosphorylation of the Y397 residue in FAK. This FAK phosp

ABSTRACT Adhesion of cells to extracellular matrix is mediated by integrin family receptors. The process of receptor-ligand binding is dependent on metabolic energy and is regulated by intracellular signals, termed inside-out signals. The strength of the initial α5β1-mediated adhesion of v-src-transformed chicken embryo fibroblasts (v-srcCEF) was similar to that of normal CEF. A chemically cross-linked fibronectin substrate was able to restore cell spreading and the ability of v-srcCEF to assemble a fibronectin matrix. Over time, v-srcCEF showed decreased adhesion due to the reduction of α5β1-

We propose that the comparison of the 3d- and v-RXES spectra is a new powerful method of directly detecting the core-hole effect in the final state of Ce L 3 X-ray absorption spectra (XAS). We applied this method to recent experimental RXES spectra for CeO 2 and CeFe 2, and showed unambiguously that the core-hole effect should be essential in the XAS of both materials. Thi

This procedure is controversial because of both the low efficacy and the low adherence to therapy by elderly patients.
