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.

Speculation on oil markets and its impact on commodity's price
Melcher, Ota ; Taušer, Josef (advisor) ; Baláž, Peter (referee) ; Müller, Štěpán (referee)
This study aims to analyse the precrisis period on the oil markets with a primary objective of assessing the role of speculation in the commodity's price development and its volatility. First it depicts the rapidly increasing speculative activity on the futures market together with the parallel oil price surge. The speculation is initially proxied by non-commercial traders' positions and subsequently quantified by Working's T-index. The paper then uses speculative traders' positions and both spot and futures prices to test for Granger causality within the framework of VAR models. For the sake of consistency it also evaluates causal links between speculation and inventories level. Further the study investigates the speculation impact on volatility of oil prices by employing various approaches in volatility quantification including GARCH models. Contrary to expectations we find that the speculatio's impact on both prices and their volatility is rather insignificant. In the last chapter we therefore seek for an explanation of the oil price developments by examining the market fundamentals. The interaction of supply and demand finally gives substantial evidence for understanding the price developments in the precrisis period.

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.

Alcohol addiction among the patients of the Psychiatric Clinic Červený Dvůr
PRAVEČKOVÁ, Michaela
My Bachelor's Thesis focuses on persons addicted to alcohol who are staying in Červený Dvůr Mental Hospital. The goal of the thesis was to find out the most frequent causes of addiction to alcohol in the Červený Dvůr clients and the impact of excessive alcohol consumption on their private life. In addition, the thesis tries to find out how the clients learned about Červený Dvůr Mental Hospital, what the reason for the consent with treatment was and what motivated the clients to undergo the treatment for addiction. The research was based on a qualitative method. The data were acquired using the method of semi-structured interviews and the sample consisted of 8 communication partners. The selection was intentional. For the data analysis, was used the method of patterns collection. The main research question dealt with the issue whether the clients in Červený Dvůr Mental Hospital are aware of the negative effect of alcohol. A partial research question was to find the answer to the question in which situations the clients became aware of the negative effect of alcohol. In addition, what were the main causes of excessive consumption of alcohol in the clients and what is their motivation to undergo the treatment for addiction. Nearly all respondents were aware of the negative effect of alcohol, specifically in relation to their family troubles. The most common consequence of alcoholism was divorce. The clients became aware of the negative influence of alcohol in the case of loss of friends or job. The most frequently occurring cause of addiction in these clients was an unidentifiable craving for a change, which they themselves are not able to explain. At the same time, for more than a half of the respondents the main motivation to undergo the treatment was their wish to live "properly" as they had lived before their addiction developed. These people wish to find the sense of their lives and their vision is that they will be able to function in everyday life as the others are. Another finding resulting from the research was that in the case of all respondents somebody from among their family members was addicted to alcohol as well. More specific results are provided in the practical part of the thesis. The Bachelor's Thesis could be beneficial for both non-specialists and specialists. It could be motivating for people who are addicted to alcohol and are afraid of seeking assistance. The thesis may be used for instructional purposes or for the creation of programmes aimed at better awareness and prevention in the area of addiction to alcohol.

STRAIN ENGINEERING OF THE ELECTRONIC STRUCTURE OF 2D MATERIALS
del Corro, Elena ; Peňa-Alvarez, M. ; Morales-García, A. ; Bouša, Milan ; Řáhová, Jaroslava ; Kavan, Ladislav ; Kalbáč, Martin ; Frank, Otakar
The research on graphene has attracted much attention since its first successful preparation in 2004. It possesses many unique properties, such as an extreme stiffness and strength, high electron mobility, ballistic transport even at room temperature, superior thermal conductivity and many others. The affection for graphene was followed swiftly by a keen interest in other two dimensional materials like transition metal dichalcogenides. As has been predicted and in part proven experimentally, the electronic properties of these materials can be modified by various means. The most common ones include covalent or non-covalent chemistry, electrochemical, gate or atomic doping, or quantum confinement. None of these methods has proven universal enough in terms of the devices' characteristics or scalability. However, another approach is known mechanical strain/stress, but experiments in that direction are scarce, in spite of their high promises.\nThe primary challenge consists in the understanding of the mechanical properties of 2D materials and in the ability to quantify the lattice deformation. Several techniques can be then used to apply strain to the specimens and thus to induce changes in their electronic structure. We will review their basic concepts and some of the examples so far documented experimentally and/or theoretically.

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.

Flodrová, Dana ; Toporová, L. ; Macejová, D. ; Laštovičková, Markéta ; Brtko, J. ; Bobálová, Janette
Bottom-up proteomic approach was used for detailed characterization of proteins from\ntwo human tumour cell lines representing major clinically different types of breast\ncancer. The aim was to show the differences between them on proteomic level. Here\nwe present almost 100 unequivocally identified proteins out of which 60 were mutually\ndifferently expressed for MDA-MB-231 and MCF-7. Some well-known breast cancer\nmarkers like annexins A1, A2 and vimentin were found in the MDA-MB-231 cell line.\nOn the other hand, MCF-7 cells were found to be positive for cytokeratins and keratins\nand thus we were able to distinguish both cell lines sufficiently.

Intuition in creative process of animation movie
Nováčková, Jana Kristýna ; DĚCKÁ, Eliška (advisor) ; ČIHAŘOVÁ, Libuše (referee)
This work deals with the relation of emotions to contemporary experimental animation. It engages in the emotional experience of a viewer to non-narrative film storytelling and its means of expression. At the same time, it examines what the creative processes and attitudes of filmmakers towards emotions in experimental animation are. Analysis of the questionnaires also reveals whether the creator counts on the viewer's specific interpretation of the film.
