Administrative Expulsion Proceedings

1 ADMINISTRATIVE EXPULSION PROCEEDINGS ABSTRACT The diploma thesis entitled as "Administrative expulsion proceedings" deals with the institute of administrative expulsion, especially its procedural side. The thesis aims to define and analyse chosen aspects of administrative expulsion proceedings from their beginning to deciding on remedies against administrative expulsion decisions. Within these, the work focuses mainly on examining the issue of the proportionality of administrative expulsion in relation existing family or private life of the expelled alien. The work is divided into four chapters. The first chapter defines the fundamental terms and clarifies the institute of administrative expulsion. First, the concept of expulsion is generally defined and then, a distinction between administrative expulsion and the penalty of expulsion is made. Furthermore, the term alien is defined because only alien can be subject of expulsion. Last but not least, the first chapter defines the concepts of family and private life, which are dealt with in detail in the third chapter. Finally, the first chapter presents national, EU and international legislation on administrative expulsion and on the fundamental right to respect for family and private life. The second chapter deals with selected aspects of administrative...ŘÍZENÍ O SPRÁVNÍM VYHOŠTĚNÍ ABSTRAKT Diplomová práce s názvem "Řízení o správním vyhoštění" se zabývá institutem správního vyhoštění, především jeho procesní stránkou. Práce si klade za cíl vymezit a analyzovat vybrané aspekty řízení o správním vyhoštění, a to od jeho počátku až po rozhodování o opravných prostředcích proti rozhodnutí o správním vyhoštění. V rámci těchto se práce zaměřuje především na zkoumání otázky přiměřenosti správního vyhoštění vzhledem k existujícímu rodinnému či soukromému životu vyhošťovaného cizince v hostitelské zemi. Práce je členěna do čtyř kapitol. V první kapitole jsou vymezeny základní pojmy a zakotven institut správního vyhoštění. Zprvu je obecně vymezen samotný pojem vyhoštění a následně je rozlišeno mezi správním vyhoštěním a trestem vyhoštění. Dále je v kapitole definována osoba cizince, neboť pouze ten může být subjektem vyhoštění. V neposlední řadě jsou v první kapitole vymezeny pojmy rodinný a soukromý život, kterými se podrobně zabývá třetí kapitola práce. Závěrem jsou v první kapitole představeny základní vnitrostátní, unijní i mezinárodní právní předpisy týkající se správního vyhoštění a základního práva na respektování rodinného a soukromého života. Druhá kapitola práce pojednává o vybraných aspektech řízení o správním vyhoštění podle zákona o pobytu cizinců....Katedra správního práva a správní vědyDepartment of Administrative Law and Administrative ScienceFaculty of LawPrávnická fakult

On the central symmetry of the circumstellar envelope of RS Cnc

We present a phenomenological study of CO(1-0) and CO(2-1) emission from the circumstellar envelope (CSE) of the Asymptotic Giant Branch (AGB) star RS\,Cnc. It reveals departures from central symmetry that turn out to be efficient tools for the exploration of some of the CSE properties. We use a wind model including a bipolar flow with a typical wind velocity of $\sim$8 km\,s$^{-1}$ decreasing to $\sim$2 km\,s$^{-1}$ near the equator to describe Doppler velocity spectral maps obtained by merging data collected at the IRAM Plateau de Bure Interferometer and Pico Veleta single dish radio telescope. Parameters describing the wind morphology and kinematics are obtained, together with the radial dependence of the gas temperature in the domain of the circumstellar envelope probed by the CO observations. Significant north-south central asymmetries are revealed by the analysis, which we quantify using a simple phenomenological description. The origin of such asymmetries is unclear.Comment: accepted for publication in Research in Astronomy and Astrophysics (RAA

An Analytical Framework Considering the Effects of Online Teaching Quality on Student Satisfaction

COVID-19 spreads across the world in late 2019 has affected to several aspects of social life. One of the most important sectors, which face difficulties was education, thus most universities have transferred from traditional education to online education through the internet to make their academic year going. This study aims to review the effects of online teaching quality on student satisfaction, a positive attitude resulting from an evaluation of students’ online teaching experience in higher education. Through applying the SERVQUAL model to measure the effects of online teaching quality on students’ satisfaction, it can be expected to get better the online teaching quality of higher education institutions in Vietnam. Keywords: Online teaching, student satisfaction, higher education, COVID-19, educational institution. DOI: 10.7176/EJBM/13-6-08 Publication date:March 31st 202

Synthesis and Optical Characterization of Dye Doped in Ormosil Nanospheres for Bioapplications

Dye-doped ORMOSIL (organically modified silicate) nanoparticles (NPs) have significant advantages over single-dye labeling in signal amplification, photostability and surface modification for various biological applications. The dyes: Rhodamine 6G (R6G) and Rhodamine B (RB) were successfully incorporated into ORMOSIL nanoparticles fabricated by micellar nanochemistry from Trimethoxysilane CH$_3$Si(OCH$_3$)$_3$ precursor. The optical characterization of dye-doped ORMOSIL NPs was studied in comparison with it’s of free dye in solution. The results shown that the photostability of ORMOSIL dye doped nanospheres is much improved in comparison with it’s of dye in solution. Other studies of the photophysical properties such as anisotropy, fluorescence lifetime and energy transfer were also done

Observation of High Doppler Velocity Wings in the Nascent Wind of R Doradus

We study the morpho-kinematics in the nascent wind of AGB star R Doradus in the light of high Doppler velocity wings observed in the spectral lines of several species. We probe distances from the star between ∼10 and ∼100 au using ALMA observations of the emission of five different molecular lines. High Doppler velocity enhancements of the line emission are observed in the vicinity of the line of sight crossing the star, reminiscent of those recently interpreted as gas streams in the nascent wind of a similar AGB star, EP Aqr. They are present in both blue-shifted and red- shifted hemispheres but are not exactly back-to-back. They are accelerated at a typical rate of 0.7 km s$^{−1}$ au$^{−1}$ up to some 20 km s$^{−1}$. Important differences are observed between the emissions of different molecules. We exclude an effect of improper continuum subtraction. However, in contrast to EP Aqr, the line of sight plays no particular role in the R Dor morpho-kinematics, shedding doubt on the validity of a gas stream interpretation. We discuss possible interpretations in terms of stellar pulsations or of rotation of the gas in the environment of the star. We conclude that, in the state of current knowledge, no fully convincing picture of the physics governing the production of such high velocities, typically twice as large as the terminal velocity, can be reliably drawn. New high resolution analyses of observations of the nascent wind of oxygen-rich AGB stars are needed to clarify the issue
