Ukládání trestů v polské a české právní úpravě / Imposing Punishments in Czech and Polish Legislations

Pustówka, Urszula January 2021 (has links)
Imposing Punishments in Czech and Polish Legislations Abstract The comparison of the legal systems of individual states is an important source of inspiration for the further development of legislation. In my work I compare the legal regulation of punishments in the Czech Republic and in Poland, namely those of them which both Czech and Polish legal systems refer to as punishments. These are Czech fines, community service, imprisonment, and an exceptional sentence together with their Polish equivalents. The aim of the thesis is to find inspiration and stimuli for de lege ferenda considerations for further development of Czech criminal law by comparing Czech and Polish regulation of punishments, as well as the types of punishments most often imposed by courts in both countries. In the first part of the work I deal with the systems of criminal sanctions in both states in order to introduce the context for the subsequently analysed punishments. Furthermore, each part is devoted to one type of punishment and a comparison of its regulation in the Czech Republic and Poland. The second part is devoted to the Czech fine and the Polish sentence of grzywna, the third part to the Czech community service and the Polish sentence of imprisonment, the fourth part is related to the regulation of imprisonment, and the fifth...

Plán opatření pro případ vzniku mimořádné události na plaveckém stadionu / Plan of Measures for Implementation in the Event of an Emergency Situation at a Swimming Pool

Macečková, Lenka January 2013 (has links)
The thesis focuses on creation of precaution „Plan applicable in case of exceptional/unsafe incidents taking place at TJ Tesla swimming pool located in Brno”. The theoretical chapter(s) deal with legislative framework and related bills regarding leak of dangerous substances from buildings. It also deals with protection of population within the Czech Republic with regard to separate measures applicable according to the character of incident. The practical chapter(s) deal with analysis of risks within the premises and define the character of unsafe attributes of the risk sources. The various risks are therefore modelled in order to show the possible range of unsafe effects on population. These models are necessary to define the most effective protective measures applicable while exceptional/unsafe incidents occur. The aim of the thesis is to create the specific precaution plan as well as dispute the way the incidents of unsafe substances of below the legislative limit amount could be handled.

Topological Aspects of Dirac Fermions in Condensed Matter Systems

Zirnstein, Heinrich-Gregor 23 April 2021 (has links)
Dirac fermions provide a prototypical description of topological insulators and their gapless boundary states, which are predicted by the bulk-boundary correspondence. Motivated by the unusual physical properties of these states, we study them in two different Hermitian quantum systems. In non-Hermitian systems, we investigate the failure of the bulk-boundary correspondence and show that non-Hermitian topological invariants impact a system’s bulk response. First, we study electronic topological insulators in three dimensions with time-reversal symmetry. These can be characterized by a quantized magnetoelectric coefficient in the bulk, which, however, does not yield an experimentally observable response. We show that the signature response of a time-reversal-invariant topological insulator is a nonlinear magnetoelectric effect, which in the presence of a small electric field leads to the appearance of half-integer charges bound to a magnetic flux quantum. Next, we consider topological superconducting nanowires. These feature Majorana zero modes at their ends, which combine nonlocally into a single electronic state. An electron tunneling through such a state will be transmitted phase-coherently from one end of the wire to the other. We compute the transmission phase for nanowires with broken time-reversal symmetry and confirm that it is independent of the wire length. Turning to non-Hermitian systems, we consider planar optical microcavities with an anisotropic cavity material, which may feature topological degeneracies known as excep- tional points in their complex frequency spectrum. We present a quantitative method to extract an effective non-Hermitian Hamiltonian for the eigenmodes, and describe how a pair of exceptional points arises from a Dirac point due to the cavity loss. Finally, we investigate generalized topological invariants that can be defined for non- Hermitian systems, but which have no counterpart (i.e. vanish) in Hermitian systems, for example the so-called non-Hermitian winding number in one dimension. Contrary to Hermitian systems, the bulk-boundary correspondence breaks down: Comparing Green functions for periodic and open boundary conditions, we find that in general there is no correspondence between topological invariants computed for periodic boundary con- ditions, and boundary eigenstates observed for open boundary conditions. Instead, we prove that the non-Hermitian winding number in one dimension signals a topological phase transition in the bulk: It implies spatial growth of the bulk Green function, which we define as the response of a gapped system to an external perturbation on timescales where the induced excitations have not propagated to the boundary yet. Since periodic systems cannot accommodate such spatial growth, they differ from open ones.

Latter-Day Saint Fathers of Children With Special Needs: A Phenomenological Study

Olson, Michael M. 01 January 1999 (has links) (PDF)
This research, presents a qualitative study of six Latter-day Saint fathers of children with special needs. In-depth interviews were used to examine the demands and resources fathers draw upon in meeting the needs of their child(ren), the application of the conceptual ethic of fathering as generative work and crisis/stress theory, as well as an analysis of how fathers incorporated their religious beliefs, faith, and practices into fathering their special needs children. Narrative accounts are used to illustrate the results. These results are then applied to an integrated conceptual framework and clinical applications are made.

Tailoring non-classical states of light for applications in quantum information processing

Tschernig, Konrad 26 October 2022 (has links)
In dieser Arbeit wird das Design und die Präparation von nicht-klassischen Zuständen von Licht in verschiedenen Szenarien untersucht. Zunächst wird die theoretische Beschreibung eines Interferometers entwickelt, welches für die Messung der Teilchenaustauschphase von Photonen entworfen wurde. Die Analyse der experimentellen Daten offenbart den bosonischen Charakter von Photonen, sowie die geometrische Phase, welche mit dem physischen Austausch zweier Quantenzustände assoziiert ist. Nach dieser Feststellung der Austauschsymmetrie von Zweiphotonenzuständen folgt die Ausarbeitung der Theorie über die Propagation von Mehrphotonenzuständen in Multiportsystemen. Dabei offenbaren sich hoch-dimensionale, synthetische, gekoppelte Strukturen die sich aus der Mehrphotonenanregung von diskreten Systemen ergeben. Basierend auf diesen Resultaten wird eine konkrete Anwendung der Theorie im Kontext von nicht-hermitischen Systemen formuliert. Dabei ergeben sich sogenannte “exceptional points” höherer Ordnung, welche Anwendungen im Bereich der Sensorik finden und ferner nur im Raum der Photonenanzahlzustände von diskreten Systemen realisiert werden können. Neben der Sensorik ist der Transport von Lichtzuständen ein wichtiger Aspekt in der Verarbeitung von Quanteninformationen. In dieser Hinsicht werden hier Photonische Topologische Isolatoren untersucht, welche eine rückstreuungsfreie Propagation entlang ihrer Ränder erlauben. Es wird gezeigt, dass partiell kohärentes Licht, Gaussisch und Nicht-Gaussisch verschränkte Zweiphotonenzustände einen solchen topologischen Schutz genießen können. Dies gilt unter der Vorraussetzung, dass die Anfangsanregung in einem wohldefinierten Bereich des topologischen Schutzes liegt, wodurch das “klassische” Bandlücken-kriterium erweitert und gestärkt wird. / In this work we study the design and preparation of non-classical states of light in several scenarios. We begin by developing the theoretical description of an interferometer, which is designed to measure the particle exchange phase of photons. The analysis of the experimental data reveals the bosonic nature of photons, as well as the geometric phase associated with the physical exchange of the quantum states of two photons. Having established the exchange symmetry of two-photon states, we proceed to develop the theory of multi-photon states propagating in multi-port systems. We unveil the high- dimensional synthetic coupled structures that arise via the multi-photon excitation of discrete systems. Using these results, we formulate an application of the theory in the context of non-hermitian systems. We find so-called high-order exceptional points, which find applications in sensing and can only be achieved in the photon-number space of discrete systems. Apart from sensing, an important ingredient for the processing of quantum information is the transport of light states. In this regard, we consider photonic topological insulators, which allow the back-scattering-free propagation along their edges. We show that partially coherent light, Gaussian- as well as non-Gaussian two-photon entangled states can enjoy such a topological protection, provided that the initial excitations fit inside a well defined topological window of protection, which strengthens the “classical” band-gap protection criterion.

Preparing elementary teachers to teach students with disabilities a comparison of program structures & elements across teacher preparation institutions

Close, Jessica 01 August 2011 (has links)
Students with disabilities have the right to the least restrictive environment (IDEA, 2004). Elementary teachers are teaching more of these students in the inclusive classroom because of this right. Elementary teachers are willing to take on this responsibility, but most feel they are not prepared to do so. In order to address this concern, elementary teacher preparation at the institution level must be addressed. This is a descriptive thesis which identifies and compares methods that different institutions across the country use to prepare teachers to teach students with disabilities. Institutions chosen for this thesis were recognized by either the U.S. News and World Report (2010) or the Report of the Blue Ribbon Panel (2010) for effective preparation of preservice elementary teachers. This thesis addresses the University of Central Florida with the aforementioned institutions. A continuum with three main types of structures was used to identify programs ranging from "discrete", meeting minimum requirements, to completely "merged" programs between special education and elementary education. While "merged" results in dual certification and the most effective preparation according to Blanton and Pugach (2007), it is most often offered as a choice and not as a requirement. Through analysis of program requirements of elementary education and special education programs, course descriptions, and syllabi, this investigator concluded that there were inconsistencies across teacher preparation programs. Institutions are distributed widely across the continuum. If elementary teachers are required to teach to all students, then teacher preparation programs should address all students thoroughly. The investigator's hope is that the evidence presented and the suggestions made in this thesis will incite changes in institutions that are preparing elementary teachers to teach students with disabilities.

Exploring the Effects of Masks on Student Engagement in ECE and ESE: A Literature Review of Related Research

Frahm, Anna M 01 January 2022 (has links)
During the advancement of COVID-19, safety protocols (including facial masks) were incorporated into public settings. The Centers for Disease Control and Prevention (CDC), due to safety regulations, recommend wearing face masks when in close contact with other people in public environments, such as in a classroom, where social distancing is difficult. Understanding these CDC recommendations is still critical when looking for effective and safe alternative forms of masking for particular industries. Many industries smoothly transitioned to daily use of traditional cloth masks, but other industries (such as education) serving clients with high communicational needs and communication-centered services sought masking alternatives. This study examines related research to explore the question of whether wearing masks may have any impacts on student engagement, particularly with regards to Early Childhood Education (ECE) or in the Education of Students with Exceptionalities (ESE). Research found that masks have a significant impact on factors of engagement (i.e., physical, behavioral, intellectual, social, emotional; The Glossary of Education Reform, 2016) and suggests transparent masks paired with Remote Microphones as a viable alternative to traditional masking. Future recommendations are provided in hopes of impacting the use of face masks with young students for both safety and for engagement. Future research should focus on ECE or ESE classrooms using observable language and literacy acquisition skills and visual cues related to the Categories of Engagement defined by The Glossary of Education Reform (2016).
