Ethics, Facebook, social network, internet, web data mining
Mácha, Petr ; Čermák, Miloš (advisor) ; Osvaldová, Barbora (referee)
The dominant part of this work is entitlement of the main ethical issues related to the participation of journalists in social networks. Emphasis is placed on the effects of hazardous or otherwise forming a journalist's reputation when he is moving in this new public space and also to study the effect of the technology itself - raising some ethical dilemmas (through the concepts of Web data mining, automatic language processing). As an ethical standard and a tool for the description was chosen selection of international and Czech editorial codes and codes of journalistic associations. Problematic actions are identified in such ontology. Statistical survey of the present work will map the participation rate of Czech journalists on Facebook.

Augustine?s Theory of the City in the Context of His Philosophy
Mácha, Petr ; Stracený, Josef (referee) ; Blažková, Miloslava (advisor)
Soudobá historická krize vedla Augustina k tomu, aby zkoumal formu a smysl historie. Energickou polemiku vede především s teoriemi, zastávajícími názor, že historická existence je ovládána osudem či štěstím a že se opakuje v nekonečných cyklech32. Tímto se staví proti znehodnocení dějinného charakteru světa. Tvrdí, že pokud měl svět "počátek", pak jde o proces, v němž se rozhodující a nové události mohou objevit a objevují se. Jsou události, které se nikdy předtím nestaly, a takovéto události mají vliv na budoucnost skutečným a účinným způsobem33, takže se ani nikdy neopakují. Biskupu hipponskému se naopak jeví "běhoun času ozdoben Božím vzorem"34, rozbíhající se od počátku ke konci. Podoba, smysl a konec dějin jsou ovládány Bohem. Vždyť i samotná doktrína Božího předzvědění a predestinace se zdá přehodnocovat otázku nutnosti a osudu. Je vyloučeno, abychom zcela pochopili Boží záměr, můžeme však přijmout to, že za vším, co se děje, je převládající účel, který je božsky správný a svatý, a tento může odporovat našim cílům a přinášet nám zklamání a bolest, ovšem nikoli bez prospěšných důsledků. Dějiny mají počátek konec, procházejí od Stvoření k dovršení35 a takto chápané se stávají skutečně vážnými a majícími význam.
