Zobrazení genderu v Zeměploše Terryho Pratchetta

This work concerns itself with the Discworld series of the British fantasy author Terry Pratchett, and with how sex and gender are depicted in it. It mainly looks at the books Feet of Clay (1996), The Fifth Elephant (1999), Monstrous Regiment (2003), and Raising Steam (2013), which deal with these topics the most openly. It attempts to reveal whether the series presents more the view that sex and gender are tightly intertwined, or even that gender does not exist at all, so-called gender critical view, or whether gender and sex are more or less independent of each other and the characters in the series may present a gender different from the one assigned to them at birth. At the same time the work examines whether the depictions of gender evolve as the series go on or not.Tato práce se zabývá sérií Zeměplocha britského fantasy autora Terryho Pratchetta a tím, jak je v ní zobrazováno téma pohlaví (sex) a rodu (gender). Zabývá se nejvíce knihami Nohy z jílu (1996), Pátý elefant (1999), Podivný regiment (2003) a Pod parou (2013), které se těmto tématům věnují nejotevřeněji. Snaží se odhalit, zda série vykazuje známky spíše pohledu, že pohlaví a rod jsou spolu velmi úzce spjaté, případně dokonce že rod jako takový neexistuje, tzv. genderově kritický pohled, nebo zda je rod na pohlaví více méně nezávislý a postavy v této sérii mají možnost vykazovat jiný rod, než jaký jim byl přiřknut při narození. Zároveň práce zkoumá, jestli se zobrazení rodu během série vyvíjí, nebo ne.Katedra anglického jazyka a literaturyFaculty of EducationPedagogická fakult

Contract of employment and formation of employment

Rigorózní práce zasazuje pracovní smlouvu do kontextu jejího působení a současného právního rámce a potvrzuje, že institut pracovní smlouvy definovaný zákoníkem práce není pouhým odrazem národního, českého práva, ale je odrazem vlivu mezinárodních závazků a práva Evropské unie. Práce prokazuje, že pracovní smlouva je neopominutelnou podmínkou pro založení pracovního poměru. Posuzuje smluvní volnost v pracovněprávních vztazích vedoucí k uzavření pracovní smlouvy a v popsaných principech právního jednání a předsmluvní odpovědnosti se zaobírá mantinely pro autonomii vůle obou stran. Zdůrazňuje význam informovanosti subjektů pracovněprávních vztahů a reflektuje odlišnosti v pracovněprávních vztazích u agenturního zaměstnávání. Práce obsahuje i návrhy de lege ferenda s odůvodněním jejich překladu a zhodnocením jejich následného přínosu v případě jejich budoucí kodifikace.ObhájenoThe dissertation puts the institute of the employment contract into the context of the effects it produces and into the current legal system, and confirms that, rather than being a mere reflec-tion of national, Czech law, the employment contract as defined in the Labour Code also re-flects the influence of international obligations and European Union law. The paper demon-strates that the existence of an employment contract is a necessary precondition for establish-ing an employment relationship. It assesses the concept of freedom of contract in employment relationships leading to the conclusion of an employment contract, and by analysing the de-scribed principles applicable to juridical actions and pre-contractual liability, it analyses the limits of party autonomy. It emphasises the importance of the ability of subjects of employ-ment relationships to make informed decisions and considers the differences that exist for agency employment relationships. The paper also presents de-lege-ferenda proposals along with justification for translating them, and describes what desirable consequences they will have if adopted into law in the future

Spezifische Züge der demographischen Entwicklung der Slowakei

The transformation processes within society which have been going on in Slovakia since 1989, are not only mirrored in the political sector and in all spheres of economic activity, rather they are also mirrored in the behaviour of the population and in their preferences of cultures and values. The demographic behaviour of the population in particular reacts very sensitively to the social transformation. When considering the population of Slovakia as a whole, natural movement plays an important role with regard to the dynamics. The development of natality and mortality, and in particular their proportionate relationship determine the growth or reduction of the population. The second component of the population movement -migration- does not have any great importance with regard to the growth and development of the population. In the assessment of the long-term development of the population of Slovakia, the tendencies towards stabilising development with the type of single reproduction proved to be dominant. This is given evidence by the long-term drop in the natality and mortality rate, and at the same time the reduction in natural growth of the population. The increase of average age in the population is a side-effect of this. The long-term tendencies of population development in Slovakia, which lead to a stabilised population and single reproduction, represent the natural components of social development. In certain analogies, this can be encountered in all European populations, and it can be presumed that similar development tendencies will take place in less developed states. The differences are expressed in the temporal asynchrony and are, of course, the result of different rates in the entire socio-economic development. In the evaluation of the population development in Slovakia during the last 6 years, the most general manifestation is the "acceleration" of the tendencies of long-term development. This applies above all for the drop in natality and the natural population growth, and therefore for the change in the age structure of the population. On the other hand, the drop in miscarriage rates, the increased age of maximum fertility and the marrying age can be regarded as positive trends. The acceleration of these development tendencies in the last six years is most noteworthy. The average annual drop in natality in the years 1950-1960 was, for example 0,11‰, whereas it achieved in the years 1990-1996 a value of up to 0,62%. The drop in values of net reproduction rate is also alarming. Since 1990, when it was at a level of 0.933, it sank in the year 1996 to 0.700. The drop in natural growth from 4,8% to 1,7% is also unusually intensive. The explanation of these negative development tendencies is quite complicated. The changes in the political and economic system in Slovakia took place in three stages. The first stage, in the years 1990-1993, had a destructive character - especially in the economic sphere. This was followed by a brief period of stabilisation - 1994-1996 - and since 1996, many economic sectors have revealed compensation and dev elopment tendencies. These stages of economic development are linked to several changes in the development of the population processes: The complicated economic situation effects a displacement of marriage, postponement of parenthood as well as a reduction in the number of children which are born. The lack of accommodation for young families is a very negative factor. The destruction phase of population development generally comes to an end when growth t endencies start to be revealed. It can also be presumed for the population of Slovakia that the negative development tendencies which were observed will not be a permanent manifestation. We can expect a positive influence of social measures which promote childbirth and, with time, also the compensation and development trends within the economy. It is very probable that the birth rate, the growth rate of the population and the reproduction rate will rise, without however exceeding the level from the year 1990

Die Industrie im wirtschaftlichen Transformationsprozeß der Slowakei

Present knowledge with regards to the course of the economic and, in particular, the industrial transformation in Slovakia confirm the exceptional complexity of the entire process of reorganisation and adaptation. Contrary to the first prognoses of development, this process has been extended timewise and its intensity has increased in many ways. The destructive phase of the transformation process was particularly marked by two factors. Firstly, the radical economic reform in Czechoslovakia between the years 1990 and 1992 - characterised by an extreme drop in production. Secondly, accompanied by a less severe drop in production, by the division of Czechoslovakia in two independent states in 1993, which obviously lengthened the destructive phase in Slovakia. Due to Slovakia's strong economic bonds to the former COMECON States (COMECON = Council of Mutual Economic Aid), the consequences of the disintegration of this economic combine were particularly grave for the Slovakian industry. The performance reduction of the national economy (a drop of 34% of the gross domestic product between 1990 and 1993) was accompanied by a strong increase in unemployment (1994: 15%). The latest results in the industrial sector are proof of the start of the stabilising phase of the transformation process. In Slovakian industry, which, with a 50% share, is the largest single contributor to the gross domestic product, extremely extensive changes have occurred in the branch and property structures. The number of employees has been reduced to a fifth of its previous level. With regards to the results of the privatisation, in the second half of 1993, the proportion of private business already amounted to 76,5%, constituting a production share of 60%. A dramatic conversion took place in the armaments industry. Its production volume sank by 90%. With regards to society, it is expected that, in the year 1995, an end of the destructive phase of the process of transformation will come about in all sectors. Some sectors may even already experience compensating elements of development. The industry will also be one of these sectors, marking a slight growth in production
