Differences and similarities on the approaches of buyers from X and Y generations regarding sustainable procurement
Lacour, Maxime ; Štěrbová, Ludmila (advisor) ; Geniaux, Isabelle (referee)
Responsible procurement has become a real challenge for companies following the current trends of Corporate Social Responsibility (CSR) and more and more ethic-oriented customers. Differing from the concept of green procurement this concept of responsible procurement supports the willingness of companies to have ethic and sustainable supplies. The usual criteria in procurement such as price performances innovation terms and time of payment have increasingly been coupled with more ethic-oriented ones. These criteria related to ethics combine both social and environmental responsibilities of suppliers and stakeholders such as energetic savings and the possession of a particular certification. Currently many call for tenders set ecological requirements for suppliers or subcontractors even in non-strategic procurement activities. The goal of this thesis is about comparing this approach to responsible procurement between buyers from the X and Y generation: do they share the same ideas and priorities concerning responsible procurement? For both of these generations are the advantages and drawbacks of responsible procurement similar?

INSTITUTIONAL CARE
PAPÁČKOVÁ, Lucie
The aim of this bachelor thesis is to acquaint the reader with institutional care in the Czech Republic, performed in facilities belonging to the Ministry of Health, the Ministry of Labor and Social Affairs, and the Ministry of Education, Youth and Sports. Institutional care is one of the most important measures in which the State may intervene in family relationships. Minors have the legal right to secure a proper education and overall development. If the parents or family are unable to fulfill this legal claim, then the State is obliged to provide the child with an alternative rearing environment, either by assigning the child to the care of individuals or a facility for children requiring immediate assistance, and in the event of a necessity, also the most important measure: imposing institutional care. Priority is always given to individual care before institutional care, either with another individual, guardian, or foster parent. The Act also defines exactly where it's possible to proceed to extreme measures and impose institutional care. Given the severity of this measure, this decision only appertains to courts. No other governmental or non-governmental institution has such authority. This paper is aimed at introducing institutional care and the protection of children in the Czech Republic, especially highlighting the fragmentation of institutional care. The fundamental part of this paper describes the process of imposing institutional care, and especially its implementation in individual institutional facilities, differentiated according to the children's age, their physical and mental abilities, and the reasons why institutional care was decided on. The priority should always be the child's interest and welfare. This work also highlights the shortcomings of institutional care, particularly the lack of cooperation between the socio-legal protection of children and institutional facilities, the limited cooperation between government departments, the lack of suitable family recovery, and the small number of social workers and judges in the field. Finally, I also mention the achievements that brought about the transformation of institutional care, particularly the conversion to small family type facilities, surrounded by a network of services for the families of allocated children, the children themselves, and also other families who find themselves in a difficult situation. Not all children can be placed in foster care, not all families can be recovered. Especially for some older children and those who have gone through a specific life experience (abuse, repeated return from foster families), an institutional facility is an environment where they feel more secure and where they can fulfill their need to belong in a group of peers. In my work, I also want to draw attention to the current system of child care for children and youth, which does not address the period following the departure of young people from institutional care, although the stage of becoming independent is the most important for their future life.

Differences between men and women in the Czech labour market
Stroukal, Dominik ; Kadeřábková, Božena (advisor) ; Pavelka, Tomáš (referee) ; Němec, Otakar (referee)
This thesis consists of five articles that apply current world research on labor economics at the Czech Republic and confirms the significant differences between men and women in this market. It shows that gender has a significant influence on the preference on the labor market and, consequently, on employment and health. First, the thesis shows that preferences are relevant determinant of career and then we study the difference in preference of salary for men and women. Subsequently it shows that gender plays a significant role in explaining the relationship between homeownership, and unemployment, as well as unemployment and health. The first chapter was able to demonstrate that the preference for a career has a positive influence on the choice of career. The influence of higher education on prioritizing career proved to be positive and significant. Probability of a career choice is reduced by the presence of children, however, is not dependent on their number, which is contrary to the theory of preferences. The second chapter shows that Czech women prefer more non-monetary rewards than men. It has also been shown that people with university education are same in the preferences of non-monetary rewards regardless of the gender of the respondents, however, compared to the world's research, the Czech higher education increases this preference. It turned out that women prefer risk less than men. The third chapter demonstrates that although the housing market undermines labor mobility and employment in the Czech Republic at the regional level, therefore, that in regions with a higher rate of home ownership is higher unemployment, at the individual level, the owners of housing are unemployed are less likely. The estimates are significantly different for men and women. Men living in owner-occupied housing have a higher likelihood of employment than women. At regional level, however, this thesis shows that the high rate of home ownership increases unemployment for both men and women, in the long run only to women. The fourth chapter showed that men transition to homeownership reduces the likelihood of unemployment next year. For women, this relationship has proved to be insignificant. In addition, as insignificant showed the opposite relationship, the transition from unemployment to the newly acquired home ownership. The last chapter shows that the change in the working status to unemployment will increase in the future probability of worse health. Influence in less than two years, however, proved to be significant. An important conclusion is that men have a significantly stronger relationship between health and unemployment than women.

HYDROGEN ABSORPTION IN A-Co30Fe55B15
Čermák, Jiří ; Král, Lubomír ; Roupcová, Pavla
Hydrogen solved in amorphous alloys (AAs) influences their magnetic characteristics. AAs are also perspective\nas additives that can improve hydrogen storage kinetic in certain types of ball-milled hydrogen storage\nmaterials (HSMs). Therefore, knowledge of hydrogen solubility and hydrogen sorption kinetics in AAs are of a\ngreat importance for aimed design both AAs with optimal magnetic parameters and HSMs with desired sorption\ncharacteristics. In the present paper, amorphous alloy Co30Fe55B15 (an example of the type a-TM1xTM2y Bz ;\nTM - transition metal) was investigated. Hydrogen concentration c H was measured by Sieverts method in\ntemperature interval from T = 150 °C to T = 350 °C under hydrogen pressure p up to 6 MPa. It was found that\nc H was an increasing function of p and its maximum value was typically 0.5 wt.% H2 at 350 °C and 6 MPa.\nHowever, when the alloy was preliminary hydrogen charged (PHC), the pressure dependence of total c Htot in\nthe first absorption cycle(s) is non-monotonous in dependence on PHC conditions. For the sake of comparison,\nthe same absorption characteristics were measured also in Mg2Ni intermetallic that is a common constituent\nin Mg-based HSMs. Comparing Co30Fe55B15 and Mg2Ni, it was concluded that Co30Fe55B15 shows lower\nhydrogen solubility, but much better absorption kinetics.

Parallel single-cell analysis of active caspase-3/7 in apoptotic and non-apoptotic cells
Ledvina, Vojtěch ; Klepárník, Karel
Caspases are proteases that play key role in the process of apoptosis, the programmed\ncell death. Among them, caspase-3 and -7 are main executioner caspases that cleave\nmany vital proteins during apoptosis and after their widespread activation, the process\ncannot be reversed. To analyze caspase-3/7 activation within single cells, a miniaturized\ndevice for parallel analysis of eight samples was developed. The assay is based on the\nmodified luciferin-firefly luciferase bioluminescence (BL) system. Individual\nsuspended cells were collected and transferred into detection microvials using a\nmicromanipulator. The bioluminescence was detected using a photon counting head\nwith cooled photcathode. The LOD suitable for detection of active caspase-3/7 in both\napoptotic and non-apoptotic cells was reached.

Alternative methods of leading childbirth
PAPAI, Daria Kristina
The topic of my bachelor thesis is "Alternative methods of child delivery". The theoretical part describes the physiological delivery its particular phases and their progression. In addition, I aim to explain what the term alternative birth means, and what it includes. The various alternative positions are described, which can be used to facilitate childbirth, as well as their appropriate use during the particular delivery phases. The theoretical part is concluded by descriptions of pain relief methods, including the description of both pharmacological and non-pharmacological methods. The second part of the thesis is a practical part, summarizes the results of an evaluation research. The aim was to explore the most used alternative methods and to identify the views and experiences of women with alternative methods and aids used during delivery in selected hospitals. Furthermore, the aim was to describe the regions of the Czech Republic in terms of the use of alternative aids and procedures. The hypotheses were formulated based on previous experiences and personal opinions of the author of the thesis. The research sample consisted of women after a spontaneous child delivery in the České Budějovice Hospital and in the Znojmo Hospital. The research was conducted in the form of an anonymous questionnaire survey, using a non-standardized questionnaires. The results of the survey were compiled in tables and the chi-square test was applied as a method for statistical processing and verifying the hypotheses.

Effect of snowpack on runoff generation during rain on snow event.
Juras, Roman ; Máca, Petr (advisor) ; Ladislav , Ladislav (referee)
During a winter season, when snow covers the watershed, the frequency of rain-on-snow (ROS) events is still raising. ROS can cause severe natural hazards like floods or wet avalanches. Prediction of ROS effects is linked to better understanding of snowpack runoff dynamics and its composition. Deploying rainfall simulation together with hydrological tracers was tested as a convenient tool for this purpose. Overall 18 sprinkling experiments were conducted on snow featuring different initial conditions in mountainous regions over middle and western Europe.
Dye tracer brilliant blue (FCF) was used for flow regime determination, because it enables to visualise preferential paths and layers interface. Snowpack runoff composition was assessed by hydrograph separation method, which provided appropriate results with acceptable uncertainty. It was not possible to use concurrently these two techniques because of technical reasons, however it would extend our gained knowledge. Snowmelt water amount in the snowpack runoff was estimated by energy balance (EB) equation, which is very efficient but quality inputs demanding. This was also the reason, why EB was deployed within only single experiment.
Timing of snowpack runoff onset decrease mainly with the rain intensity. Initial snowpack properties like bulk density or wetness are less important for time of runoff generation compared to the rain intensity. On the other het when same rain intensity was applied, non-ripe snowpack featuring less bulk density created runoff faster than the ripe snowpack featuring higher bulk density. Snowpack runoff magnitude mainly depends on the snowpack initial saturation. Ripe snowpack with higher saturation enabled to generate higher cumulative runoff where contributed by max 50 %. In contrary, rainwater travelled through the non-ripe snowpack relatively fast and contributed runoff by approx. 80 %.
Runoff prediction was tested by deploying Richards equation included in SNOWPACK model. The model was modified using a dual-domain approach to better simulate snowpack runoff under preferential flow conditions. Presented approach demonstrated an improvement in all simulated aspects compared to the more traditional method when only matrix flow is considered.
