?We all Black innit??: Analysing relations between African and African-Caribbean groups in Britain
‘We all Black innit?’ examines ‘intra ethnic’ relationships between second and third generation members of British African and British African Caribbean groups, located in two key urban settings (London and Birmingham). Through unstructured interviews, it explores ways in which positive informal/formal ‘race based coalitions’ (Rogers 2004), have been forged, partly as a result of supporting and celebrating each other’s contributions to professionality (e.g education and work), and popular culture (e.g music and sports). Moreover, it discusses how members of these generations have come to embrace difference and commonalities in terms of ‘histories language and culture’ (Hall 1988:5), and the role of ‘pan ethnicity’ in facilitating these positive relationships. There is, however, acknowledgement of ‘intra ethnic’ tensions existing between these groups, largely resulting from historical (and often negative) stereotypes of each other’s cultural attributes (Mwakigale 2009, Fanon 1952), and competition for scare socio-economic resources, intensified by allocation along colour or ethnic lines (Malik 2012). The findings suggest that although this appears to have been a greater issue for migrant generations who arrived in Britain, especially between the post war era and the 1980s, to an extent it has impacted on ‘intra ethnic’ relations between the second and third generations. In the main, however, it would seem that the mutual respect between younger generations of British African and British African Caribbean people, has grown with time
System for extracting information from criminalistic texts
Práce se zabývá zpracováním nestrukturovaných dokumentů a následným zpracováním extrahovaných dat. Největší pozornost je věnována extrakci jmen osob, ze kterých je následně vytvářena sociální (kriminální) síť. Dále je ukázán způsob, jakým tuto síť efektivně destabilizovat. V práci jsou ukázány možnosti detekce komunit, které se spolu často v textech vyskytují, prostorové a časové analýzy. Systém by mohl usnadnit práci např. investigativním reportérům nebo policii, která má k dispozici velké množství textových dokumentů. Jejich ruční zpracování, zejména pokud jsou hledána vodítka napříč několika dokumenty, může být obtížné. Jelikož tyto záznamy mohou obsahovat osobní údaje, je zde představen anonymizátor, který tyto údaje dokáže anonymizovat a následně deanonymizovat. Funkčnost systému byla ověřena na testovací sérii článků, které se věnují teroristickým útokům v Paříži a Bruselu.ObhájenoThe aim of this diploma thesis is processing of unstructured documents and further data processing of extracted information. The main attention was devoted to extraction of personal names. From obtained personal names was created a social (criminal) network. An effective destabilization of this network is shown. Also the detection of communities, which occur frequently together is demonstrated and the example of spatial and the temporal analysis is presented. Our system could facilitate the work of investigative reporters or police, which has an available large set of unstructured documents. Manual processing of these documents may be difficult. Mainly, if they look for clues between multiple documents. However, these documents may contain some personal data. Therefore the anonymizator was created similarly as the deanonymizer. The function of this system is demonstrated. Used test data was created from articles on terrorist attacks in Paris and Brussels
Analysis of the social network of friends
Práce se pomocí analýzy rozsáhlé online sociální sítě přátelství zaměřuje na přiblížení možností, které analýza sociálních sítí nabízí. Naleznete zde návrh webového robota, který prošel více než milion webových stránek nacházejících se na online sociální síti Lidé.cz. Jsou zde uvedeny statistiky zabývající se sociodemografií tohoto serveru a je zde uvedeno, jaké informace pomocí analýzy obsahu sociálních sítí lze získat. Získaná síť je poté verifikována oproti teoretickým modelům. Též jsou zde pomocí několika základních metod Centrality measures (Degree, Closeness a Betweenness centrality) určeny nejvýznamnější uživatelé nacházející se v této síti. Práce se též zabývá ověřením hypotézy malého světa.Katedra informatiky a výpočetní technikyObhájenoThis thesis introduces the opportunities that social network analysis offers by analyzing online large-scale social network of friendship. Thus, you will find here a design of the web crawler, which has successfully crawled more than a million web pages located on the online social network called Lidé.cz. In the thesis you will also find statistics which show socio-demographics of this server. It is also stated what kind of information you can obtain through the analysis of online social network content. The above mentioned social network is then verified against the theoretical models. Furthermore, there are rankings which contain the most important users of this network. These rankings were created by using basic Centrality measures methods (such as Degree, Closeness and Betweenness centrality). In addition the small-world theory is verified

Comparative study of taste substance sensing by liquid membrane oscillator and electrochemical systems with all-solid-state electrodes
In food industry, different types of sensors are used for characterizing and quantifying taste substances. Therefore, it is important to establish the principal advantages and disadvantages of these sensors for optimal application. In this paper, two possible systems are compared for sensing the four fundamental tastes: sour (citric acid), salty (sodium chloride), sweet (sucrose), and bitter (caffeine or quinine hydrochloride). One system is a bulk liquid membrane oscillator containing benzyldimethyltetradecylammonium chloride surfactant present during its transport in nitrobenzene membrane phase. The other system is based on all-solid-state electrode (ASSE) containing the same surfactant dissolved in polymer support. It was shown that the liquid membrane oscillator is significantly more sensitive to the presence of taste substances than the ASSE III system. Unfortunately, the functioning characteristics of this oscillator prevent it from steady, repetitive application in food quality control. On the other hand, ASSE III system shows remarkable stability on the long run. It was also found that a system composed of several ASSEs III, each containing different lipid compound, can distinguish successfully substances belonging to different taste classes. The obtained results suggest that such ASSEs III system can be used for food analysis
