Confidence Cycles and Liquidity Hoarding
Audzei, Volha
Market confidence has proved to be an important factor during past crises. However, many existing general equilibrium models do not account for agents’ expectations, market volatility, or overly pessimistic investor forecasts. In this paper, we incorporate a model of the interbank market into a DSGE model, with the interbank market rate and the volume of lending depending on market confidence and the perception of counterparty risk. In our model, a credit crunch occurs if the perception of counterparty risk increases. Our results suggest that changes in market confidence can generate credit crunches and contribute to the depth of recessions. We then conduct an exercise to mimic some central bank policies: targeted and untargeted liquidity provision, and reduction of the policy rate. Our results indicate that policy actions have a limited effect on the supply of credit if they fail to influence agents’ expectations. Interestingly, a policy of a low policy rate worsens recessions due to its negative impact on banks’ revenues. Liquidity provision stimulates credit slightly, but its efficiency is undermined by liquidity hoarding.

A pair of phase-synchronized semiconductor lasers for length metrology
Hucl, Václav ; Holá, Miroslava ; Čížek, Martin ; Řeřucha, Šimon ; Pham, Minh Tuan ; Pravdová, Lenka ; Lazar, Josef ; Číp, Ondřej
Semiconductor lasers are increasingly widespread in areas that have been so far dominated by He-Ne lasers. One of such areas is the length metrology, where He-Ne laser operating at 633nm wavelength is still a traditional source of coherent light for laser interferometers distance measuring. The advantages of semiconductor lasers compared with He-Ne laser are greater optical power and a significantly wider range of wavelength tuning without mode jumps. Another advantage is the possibility of frequency modulation of wavelength of the laser diode by directly changing the injection current. The benefits predetermine these laser diodes for the realization of dual-frequency laser sources for heterodyne interferometry. In this case, using a phase-locked loop technique the optical frequency of a laser diode is locked to the optical frequency of another laser diode with a certain frequency offset in the MHz order. In our contribution we present utilization of DBR laser diodes in implementing a dual-frequency laser source for laser interferometry with heterodyne detection.\n

Cultural Centres
Adolfová, Barbora ; PROKOP, Petr (advisor) ; KAŠPAR, David (referee)
This thesis is concentrated on cultural centres built between years 1960 and 1990 in the former socialist Czechoslovakia. Six cultural centres have been chosen and analyzed to conclude the purposes they serve as well as the programs they offer. These chosen cultural centres are run as municipal organisations financed from the town budgets. The six towns where they are located are similar to each other in terms of their history, size and the time when their cultural centres were built. All of these centres share difficulties with the lack of cultural interest of local citizens, bad technical shape of the buildings in question and low budget.
The aim of this thesis is to compare the functioning of these six cultural centres and conclude whether being directly funded and influenced by the municipal councils has a positive impact and should serve as a model for cultural centres or should be replaced by a different one. It also focuses on cooperation between the management of cultural centres and municipal officials, cooperation with other local cultural institutions and cultural centres from different towns.

Characteristics of the working behavior of Czechs and Ukrainians
BYKOVA, Sofia
The aim of this work is to create a transparent and comparable characteristics of the work behavior phenomenon within the cultures of those states - what is common and what is different between them, or maybe incompatible .It is supposed to have some analysis of possible conflicts and their connection with the mentality. The primary reason of this aim choosing is the specialty I study. My work contains information that could be interesting and useful not only for me and my future job, but also for managers and other employees. Overview of examined issues contains specific points, such as the fundamentals of economic psychology and behavioral economics (symbiosis of psychological and economic opinion on motivation and rationality of individuals), theories of motivation and reaction to different occurrence, characteristic of the term "mentality", general points about the human impact of the world economy. For realizing the goals of my work the following hypotheses have been proposed - Czech and Ukrainian mentality have significant differences, though these cultures are close. - Ukrainian and Czech employees are able to work effectively in a team and find a "common language" in the workplace. The difference in mentality does not obstruct on it. - Employers could be interested in the Ukrainian employees taking into account their high concernment and motivation. All three of the hypotheses were confirmed by observed data and comparison of mentality characteristics. Czechs are often tolerant to other cultures, moreover Ukrainian culture is not much different and does not create difficulties in the working relationship. Based on the fact that the chosen company has no conflicts associated with work behavior and differences in mentality, it's hard to define my contribution to this organization work.

Project management in selected company
POKORNÝ, Radek
This work deals with project management in chosen company. It has two parts. The first part is theoretical, which is focused to theoretical treatment of the subject. It explains what is the project, management of projects, organizations of projects, processes of project management, what is target of project, communication, control, changes and risks and more. In the practical part I focused to concrete company and project management and than I analyzed concrete project. Name of the mentioned company is OHL ŽS, a.s. It is company from Spain, which acts all over the world. In the Czech Republic has the base in Brno. This company has several divisions and every of them is focused to different professional architecture. I have chosen division of structural engineering. This division builds all kinds of buildings. It could be construction of new buildings or reconstruction. To analysis of chosen project I used various business documents, contracts with investor or suppliers, document which include billing, timetable. I especially used my experience with projects of this company, and I was part of this project. Name of this project is Reconstruction of cladding including replacement windows and insulation. During the analysis of project I found a couple major gaps. If we could avoid these gaps, we could increase profit. These graphs is especially in management. At the beginning there were appointed two temporary construction managers. They doesn't care about result project, because they knew that they will not be to the end of the project. These gaps are because there is missing motivation system. Project manager can´t affect results of employees. It doesn´t depend on performance of employees, they always has the same wages. For elimination of these gaps I proposed several suggestions for improvement. The first suggestion is modification and extension of motivation system. New motivation system include personal evaluation. This evaluation depends on performance of employee. The second part is bonus from over profit. The next suggestion is make a new working position. This position would take care about controlling and project documentation. During the building project, especially at the end is construction manager very busy. It depend of decision of construction 63 manager what kind of activity will have prefer. Project documentation and administration or controlling of building works. If they are doing everything correct and technology are respect. Suggested position would take care about invoices, real work, which is done, project documentation, controlling of budget. The third suggestion is purchase of small machinery such as chipping hammers and drills. At this time they rent all devices. Rent is higher than purchase price. The last suggestion is use credit to restoration of fleet. At this time they have obsolete fleet, because the bought all cars by cash. It is not conveniently.

Expression of selected proteins in sperm in men with normal and pathological spermiograms using monoclonal antibodies
Pěknicová, Jana ; Čapková, Jana ; Dorosh, Andriy ; Margaryan, Hasmik ; Kubátová, Alena ; Děd, Lukáš
Recent studies show that infertility in human populations it affects an estimated 15% of couples of reproductive age. Male infertility is the primary cause for 60% of these cases. For these reasons, we analyzed the acrosomal and sperm surface proteins in men with normal and pathological spermiograms. We found that intra-acrosome proteins: TERA (Transitional endoplasmic reticulum ATPase), GAPDHS (Sperm Glyceraldehyde-3-phosphate dehydrogenase), and PRKAR2A (C-AMP-dependent protein kinase II, PRKAR2A), which can be identified using our monoclonal antibodies, are different express in healthy men and men with astenozoospermia (with reduced sperm motility), and with a significantly reduced expression in the astenozoospermia. These proteins are involved in energy metabolism and apoptosis of the cells, and some of them in the sperm-egg interaction; therefore, they have an important role in reproduction. On the other hand, there were no statistically significant differences in the expression of surface proteins (Appolipoprotein J (Clusterin) and Semenogelin). Our findings show that astenozoospermia as a complex disorder of the semen is often combined with other pathological conditions that are not diagnosed by the semen analysis. Therefore monoclonal antibodies are so suitable instrument for the detection of proteins associated with the pathology of the sperm in the semen with low sperm motility. In general, monoclonal antibodies against the sperm proteins are an appropriate tool to detect sperm quality in reproductive medicine.

High normal pressure and hypertension of children and adolescents
KRÁLOVÁ, Kateřina
In children and adolescents, high normal blood pressure is often present. People with high normal blood pressure show a short time prerequisite to the formation of arterial hypertension. Hypertension occurs most often in children as asymptomatic. Increased blood pressure in children is most often discovered during preventive examinations by a general practitioner for children and adolescents. This thesis contains information about the anatomy and physiology of the cardiovascular system, a blood pressure measurement sister, evaluation of blood pressure, high normal pressure, high blood pressure in children, the role of nurses in primary care pediatricians in the area of communication and education, and treatment of high normal pressure and hypertension. Objectives The first goal was to explore how children adhere regime measures for the prevention of high normal pressure and hypertension. It used this research question: How children adhere regime measures for the prevention of high normal pressure and hypertension? The second objective was to determine the role of nurses in the care of children with high normal pressure and hypertension. The second research question is: What is the role of the nurses in taking care of children with a normal high pressure and hypertension? Methods used In the research part of the thesis, we used the method of qualitative research, questioning method and technique-depth interviews. The interviews were recorded on a Dictaphone and then transcribed literally. Four sisters and three mothers did not wish to be recorded, so they were interviewed at polling literally written on paper. For research, two research files were created. The first sample consisted of six nurses, who were working in GP surgery for children and adolescents in the South Region. Second survey consisted of six people selected from among parents of children with high normal pressure and hypertension, also from South Bohemia. Results The transcribed interviews were investigated by open coding method, pencil and paper. Resulted in 9 categories: Cardiovascular disease, role of the nurse, pressure measurement, blood pressure, hypertension, pressure measurement, recommendation, Lifestyle, Leisure. Individual categories were assigned to subcategories, which are encoded core data. Conclusion The first research confirms nurses working in a pediatrician's office for children and adolescents, the most common cardiovascular disease in the general hypertension. They argue that the role of nurses in primary care pediatricians is properly measure blood pressure and make the education of children and parents in the area. The respondents concurred in the principles of how to properly measure blood pressure measurement are available for at least three cuff sizes. Informants have basic information about high normal pressure and hypertension, and said that, in the offices of primary care pediatricians to conduct checks blood pressure of preventive examinations or troubled child. Informants reported that blood pressure control and education on blood pressure occurs, but in the second research study showed that children and adolescents do not comply with the recommended recommendations in this area, perhaps because they are less motivated. Neither sister nor the parents have not mentioned, they would receive educational aids such as brochures and sample menus.The second research showed that parents most often found elevated blood pressure in primary care pediatricians, either for reasons of preventive examinations or difficulty a child. On the control measurements came at least three times. Respondents agreed on the recommendations they received in the office GPCY such as reducing the weight of the child, regular physical activity, restriction of salt and proper diet the child, but not all children and adolescents comply with these recommendations. The research results will be provided to the journal Pediatrics practice.

Role and competences of the nurse in compared with Czech Republic and Namibia
KLYNCYPAROVÁ, Hana
Theoretical grounds The nursing profession among the professions and mission. Job nurse is one of very important professions. Nurse is an independent worker who has an irreplaceable role in the provision of care. In practice, certain roles, such as the role of a caregiver, the educationalist, communicator, the role of the lawyer, consultant, person, who brings the change, manager and researcher. These roles are constantly interacting and are interconnected. Health care has multidisciplinary and multiprofessional character. Although each of these professions contribute to care in a unique way, all share certain skills that are necessary to ensure the quality of care. Over the years there have been increasing professional skills and increase competencies. Expanded the range of services for which they previously did not have the competence or sisters had a written authorization of a doctor. This work is made up of theoretical and empirical part. The theoretical part provides an overview and information on the field of nursing and its history, dealing with the care system and education system in the Czech Republic and Namibia. The following list of findings roles and their importance in the nursing profession. The last part deals with the competencies of nurses in both countries. The aim of the thesis: The aim of the study was to determine the roles and responsibilities of nurses in the Czech Republic and Namibia. To to obtain this information were chosen research question what role nurses advocate in the Czech Republic and Namibia, and what are nurses in the Czech Republic and Namibia competence. Methods: To ensure the necessary data and information was chosen qualitative research through deep interviews. Nurses who were interviewed were from a hospital in the Czech Republic and nurses from hospitals in Namibia Keetmanshoop. All interviews were recorded on a Dictaphone andwritten down on the paper. Results: Recorded interviews were analyzed after writing down, we were using paper and pencil methods. Dialogs were openly coded. The analysis of these data arose following categories: the role of caregivers, the role of the teacher, communicator, the lawyer's role, the role of counselor, role of person who brings the change, the role of leader, manager's role, the role of researcher and categories of competence. Individual categories were assigned to subcategories. All informationwere are illustrated by clear diagrams of the individual categories. Conclusion: The Research shows that nurses have a general maintenance of the roles and competencies, actually both of sides, Namibia and Czech Republic also. both groups were mostly able to define roles in nursing care. Surprisingly czech nurses most failed in the role of the Advocate, while African colleague have proven to be very informed. Research also showed negative effect of paperwork and administration in czech system. Nurses having feeling they do not provide active care as they would be able to. Czech nurses seems also low initiative and ambitious, Czech nurses do not desire for increasing competence on the other hand African nurses, who have more competencies, want still more, than they already have.
