Domestic violence against the elderly
Königová, Ludmila ; Šťastná, Jaroslava (advisor) ; Řezáč, Karel (referee)
The topic of this bachelor thesis is Domestic violence against the elderly. I was led to work on this topic by my interest stemming from my experience with a case of domestic violence against an elderly woman from the time when I worked as a carer in a home care service center. This experience awakened in me the subject for this bachelor's thesis and the interest to deal more with this issue in the future, within the profession as a social worker. The thesis presents the issue of domestic violence against the elderly and research into the methods and quality of assistance to victims by providers of field and residential care service. The bachelor's thesis consists of two parts, theoretical and practical. In the theoretical part I define the terms senior and old age, domestic violence, perpetrator of domestic violence, consequences of domestic violence and possibilities for help and prevention. The practical part of this thesis includes qualitative research, focused on the method and quality of assistance to victims of domestic violence among the elderly provided by field and residential care service facilities. Keywords social work, senior, senium, domestic violence, aggressor, victim, prevention, assistance, social service

This contribution deals with observations of relativistic electrons produced in a laser plasma interaction experiment at the PALS laser system operated at the Institute of Plasma Physics in Prague. The PALS laser is a near-infrared 3-TW iodine laser designed to deliver irradiance on target of 1016 Wcm2- in≈300 ps pulses at the wavelength of 1.315 μm. Various foils of 6 500 μm in thickness were irradiated with Iλ2 ≈5×1016 W cm-2 μm2 Under these conditions we have observed relativistic electrons expanding into the vacuum with maximum energy going beyond 4 MeV. The relativistically accelerated forward electrons escaping from the rear target surface were observed with the use of electron energy analysers. The observed electron energy spectra indicate that the applied laser intensity was increased by the thermal and relativistic self-focusing. The application of a unique femtosecond interferometry technique allowed us to observe bunches of thermal electrons occurring in the plasma expanding against the focused laser beam.
