    Endogenous measures for contextualising large-scale social phenomena: a corpus-based method for mediated public discourse

    Get PDF
    This work presents an interdisciplinary methodology for developing endogenous measures of group membership through analysis of pervasive linguistic patterns in public discourse. Focusing on political discourse, this work critiques the conventional approach to the study of political participation, which is premised on decontextualised, exogenous measures to characterise groups. Considering the theoretical and empirical weaknesses of decontextualised approaches to large-scale social phenomena, this work suggests that contextualisation using endogenous measures might provide a complementary perspective to mitigate such weaknesses. This work develops a sociomaterial perspective on political participation in mediated discourse as affiliatory action performed through language. While the affiliatory function of language is often performed consciously (such as statements of identity), this work is concerned with unconscious features (such as patterns in lexis and grammar). This work argues that pervasive patterns in such features that emerge through socialisation are resistant to change and manipulation, and thus might serve as endogenous measures of sociopolitical contexts, and thus of groups. In terms of method, the work takes a corpus-based approach to the analysis of data from the Twitter messaging service whereby patterns in users’ speech are examined statistically in order to trace potential community membership. The method is applied in the US state of Michigan during the second half of 2018—6 November having been the date of midterm (i.e. non-Presidential) elections in the United States. The corpus is assembled from the original posts of 5,889 users, who are nominally geolocalised to 417 municipalities. These users are clustered according to pervasive language features. Comparing the linguistic clusters according to the municipalities they represent finds that there are regular sociodemographic differentials across clusters. This is understood as an indication of social structure, suggesting that endogenous measures derived from pervasive patterns in language may indeed offer a complementary, contextualised perspective on large-scale social phenomena

    Робота публікується згідно наказу ректора від 27.05.2021 р. №311/од "Про розміщення кваліфікаційних робіт вищої освіти в репозиторії НАУ". Керівник дипломної роботи: професор кафедри авіоніки, Грищенко Юрій ВіталійоичThe current state of the global air transport industry is characterized by a stable increase in the volume of air transport, which is already leading to it reaching its limit. Further growth in the intensity of air traffic inevitably leads to a decrease in the safety and efficiency of flights, an increase in fuel costs and delays of aircraft (DO) both on the ground and in the air, and an unacceptable increase in environmental costs. The high traffic intensity in the European network of air routes directly affects the increase in the number of potential conflict situations. As a result, ground control centers face a significant overload when regulating air traffic flows. The term "dynamic object" (DO) refers to a manned or unmanned aircraft designed to perform a target flight under specified conditions. Conflict situations (CS) are events that correspond to an actual or predicted violation of the rules for ensuring the echeloning of aircraft in space and, in the absence of appropriate actions by pilots or air traffic control authorities, can lead to a catastrophic situation - a collision of aircraft. As for the concept of "managing" conflict situations, it also includes the concept of conflict resolution. Modern air traffic control (ATC) requirements are as follows: - increasing the capacity of the ATC system; - flexible use of air space; - the ability to fly along optimal trajectories; - dynamic correction of flight plans; - reduction of flight arrival delays; - minimization of aircraft deviations from planned trajectories; - ensuring a high guaranteed level of flight safety, etc.Сучасний стан світової галузі авіатранспорту характеризується стабільним зростанням обсягів авіаперевезень, що вже призводить до їх межі. Подальше зростання інтенсивності повітряного руху неминуче призводить до зниження безпеки та ефективності польотів, збільшення витрат на паливо та затримок повітряних суден (ПС) як на землі, так і в повітрі, неприпустимого зростання екологічних витрат. Висока інтенсивність руху в європейській мережі повітряних трас безпосередньо впливає на збільшення кількості потенційних конфліктних ситуацій. У результаті наземні диспетчерські центри стикаються зі значним перевантаженням при регулюванні потоків повітряного руху. Термін «динамічний об'єкт» (DO) відноситься до сконструйованого пілотованого або безпілотного літального апарату для виконання цільового польоту за певних умов. Конфліктні ситуації (КС) - це події, які відповідають фактичному або прогнозованому порушенню правил забезпечення ешелонування повітряних суден у космосі і за відсутності відповідних дій пілотів або органів управління повітряним рухом можуть призвести до катастрофічної ситуації - зіткнення літаків. Що стосується поняття «управління» конфліктними ситуаціями, то воно включає також поняття вирішення конфлікту. Сучасні вимоги до управління повітряним рухом (УПР) полягають у наступному: - підвищення пропускної здатності системи УПР; - гнучке використання повітряного простору; - можливість польоту по оптимальних траєкторіях; - динамічна корекція планів польоту; - зменшення затримок прибуття рейсів; - мінімізація відхилень ПС від запланованих траєкторій; - забезпечення високого гарантованого рівня безпеки польотів тощо

    The Ephemeral City : Songs for the Ghost Quarters

    Get PDF
    The towers of the Stockholm skyline twine with radio transmissions, flying out over the city, drifting down through the streets and sinking into the underground telephone system below. Stockholm has buildings that have been there for centuries, but is also full of modern and contemporary architectures, all jostling for their place in parallel collective memory. In taking the city up as a subject, this artistic PhD project in music expands allegories to these architectural instruments into the world of the mechanical and the electrical. By taking up and transforming the materials of the cityscape, this project spins ephemeral cities more subtle than the colossal forces transforming the cityscape. The aim is to empower urban dwellers with another kind of ownership of their city.The materials in the project are drawn around themes of urban memory and transformation, psychogeography and the ghosts of the imagined city. There are three questions the artistic works of this project reflect on and address. The first is about the ability of city-dwellers to regain or create some sense of place, history or belonging through the power of their imaginations. The second reflects on the possibility for imagined alternatives to re-empower a sense of place for the people who encounter them. The third seeks out the points where stories, memories, or alternative futures are collective, at what point are they wholly individual, and how the interplay between them plays out in listening.There is an improvisatory practice in how we relate to urban environments: an ever-transforming inter-play between the animate and inanimate. Each individual draws phantoms of memory and imagination onto the cityscape, and this yields subtle ways people can be empowered in their surroundings. The artistic works of this project are made to illuminate those subtleties, centering around a group of compositions, improvisations, artistic collaborations and sound installations in music and sound, utilizing modular synthesizers, field recordings, pipe organs, multi-channel settings; PureData and SuperCollider programs, string ensembles with hurdy-gurdy and nyckelharpa or violin, and sound installations. This choice of instruments is as an allegory to the architecture of Stockholm. The final result is a collection of music and sound works, made to illuminate the imagined city. Taken as a whole, the works of the project create an imaginary city–The Ephemeral City–in order to argue that this evocation of ephemeral space is a way to empower urban dwellers through force of imagination, immune to the vast forces tearing through the fabric of Stockholm life by virtue of the ghostly, transitory and mercurial, as compelling to the inner eye as brick and mortar to the outer life

    MIMO無線伝送に適したスケーラブルビデオコーディングに関する研究

    Because of the COVID-19 pandemic, a new normal has taken over. It affects the higher demand for using video traffic. H.264/SVC is the video compression standard with several advantages compared with the previous standard, such as a smaller storage space and scalability of video quality depending on network quality. The H.264/SVC bitstream includes one base layer (BL), the most important layer, and one or more enhancement layers (EL) which can be leveraged to optimize the video scalability depending on the network condition and user preferences. The method of transmission is powerful as the video coding method. The transmission of the good video quality will not be effective without a suitable transmission method. In this thesis, we study and research the H.264 scalable video coding transmission with IEEE 802.11ac standard MIMO wireless transmission. We focus on the suitable transmission method for H.264/SVC in a different environment. We divide the research focusing on two issues: 1. With the difference channel environment: The suitable H.264/SVC transmission technique in IEEE 802.11ac with the specific quantization parameter of video encoding was proposed. This aim is to compare three techniques in IEEE 802.11ac: STBC, SISO, and MIMO. In this focus, only the accuracy of the video was considered to measure the efficiency of the transmission technique. This part proposed to utilize STBC to improve the quality of H.264/SVC video transmission. We have shown the performance of H.264/SVC video transmission with three multiple antenna techniques. The results show that STBC is the best technique for H.264/SVC transmission under a low-quality channel environment. The best result shows that STBC in channel model D can improve the PSNR by 67 percent and 76 percent compared with SISO and MIMO, respectively, at low SNR of 20 dB. Due to STBC transmitting multiple copies of data, it can increase data reliability. We proved that STBC is the most suitable multiple antenna technique to improve the quality and realizability of video transmission in both PSNR and bit error rate (BER). 2. With the different transmission distance: H.264/SVC video transmission on MIMO with RSSI feedback was proposed. This aim to proposes the allocation of packetization in the transmission packet and the compromising of quantization parameter encoding both vary on the channel efficiency. This part proposed a MIMO transmission system for H.264 scalable video coding that does not require full CSI feedback. Instead of the CSI feedback, we have used the RSSI and table of encoding rules obtained via link simulation in MATLAB. The encoding rule takes the form of the encoding ratio between the base and enhancement layer, which was done by adjusting the quantization parameter. This proposed system has been shown to improve the PSNR by at least 16 dB and increase the effective distance of 6 meters above compared with the conventional method.九州工業大学博士学位論文 学位記番号:情工博甲第372号 学位授与年月日:令和4年12月27日1 Introduction|2 Video Transmission System Overview|3 H.264/SVC Video Transmission by IEEE 802.11ac Techniques|4 H.264/SVC Video Transmission on MIMO with RSSI Feedback|5 Conclusion and Future Work九州工業大学令和4年

    Performance, memory efficiency and programmability: the ambitious triptych of combining vertex-centricity with HPC

    Get PDF
    The field of graph processing has grown significantly due to the flexibility and wide applicability of the graph data structure. In the meantime, so has interest from the community in developing new approaches to graph processing applications. In 2010, Google introduced the vertex-centric programming model through their framework Pregel. This consists of expressing computation from the perspective of a vertex, whilst inter-vertex communications are achieved via data exchanges along incoming and outgoing edges, using the message-passing abstraction provided. Pregel ’s high-level programming interface, designed around a set of simple functions, provides ease of programmability to the user. The aim is to enable the development of graph processing applications without requiring expertise in optimisation or parallel programming. Such challenges are instead abstracted from the user and offloaded to the underlying framework. However, fine-grained synchronisation, unpredictable memory access patterns and multiple sources of load imbalance make it difficult to implement the vertex centric model efficiently on high performance computing platforms without sacrificing programmability. This research focuses on combining vertex-centric and High-Performance Comput- ing (HPC), resulting in the development of a shared-memory framework, iPregel, which demonstrates that a performance and memory efficiency similar to that of non-vertex- centric approaches can be achieved while preserving the programmability benefits of vertex-centric. Non-volatile memory is then explored to extend single-node capabilities, during which multiple versions of iPregel are implemented to experiment with the various data movement strategies. Then, distributed memory parallelism is investigated to overcome the resource limitations of single node processing. A second framework named DiP, which ports applicable iPregel ’s optimisations to distributed memory, prioritises performance to high scalability. This research has resulted in a set of techniques and optimisations illustrated through a shared-memory framework iPregel and a distributed-memory framework DiP. The former closes a gap of several orders of magnitude in both performance and memory efficiency, even able to process a graph of 750 billion edges using non-volatile memory. The latter has proved that this competitiveness can also be scaled beyond a single node, enabling the processing of the largest graph generated in this research, comprising 1.6 trillion edges. Most importantly, both frameworks achieved these performance and capability gains whilst also preserving programmability, which is the cornerstone of the vertex-centric programming model. This research therefore demonstrates that by combining vertex-centricity and High-Performance Computing (HPC), it is possible to maintain performance, memory efficiency and programmability

    Hegemony of BBC, CNN and Al Jazeera’s Framing of Protests in China: The Cases of Wukan and Hong Kong

    This study focuses on how the global news media report on protests in China. It contributes an original analysis of the global news media coverage of protests in China from both the theoretical and empirical perspectives. The research is based on the purposive sampling of the BBC, CNN and Al Jazeera English, in order to discuss how international news media outlets report on protests in mainland China and Hong Kong, especially given that they are non-Western contexts. Samples from Wukan and Hong Kong are evaluated by using both quantitative and qualitative methods, including qualitative analysis software (NVivo), framing analysis and critical discourse analysis to determine the ways in which they are represented by the selected news outlets. The main findings have revealed hegemony in the news representations of protests in China, which includes biases, domestication, and geopoliticised news angles. The analysis in the Wukan case showed that the reports offered a limited voice to the Chinese side, while carrying frames of bias from Western journalists. The analysis of the selected global news reports unmasked ideological presuppositions about Chinese political reform, including the perception that the Chinese regime was monolithic, and that most Chinese protesters craved Western democracy. On the contrary, the evidence from the Al Jazeera documentary analysed in this study illustrated a Chinese government that is loosely structured, and that the protesters were more concerned about the land issue than they were about political ideology. As for the Hong Kong case, the results indicated that there were traces of domestication and the geo-politics of news regarding HK protests in both CNN and the BBC in relation to several topics, whereas Al Jazeera had a slightly different approach to reporting the protests: The BBC and CNN tended to relate protests with domestic politics and topics, while AJE balanced pro-Britain and pro-America discourse among the protesters. The study also discussed Orientalism, which is still highly relevant to Hong Kongers’ identity issues, and how Western media report on China today. The research findings add to work by other scholars in media and journalism that has questioned the partiality of leading international or global (Western) media, particularly when it comes to reporting on non-Western and less developed countries. The research adds original evidence and insights to debates on the hegemony of international news coverage of protests, in the context of the Global South. It should be noted that leading media from the dominant Global North, in this case, excluding Al Jazeera, project the interests of the developed countries while voices from the Global South are less heard

    Platform://Democracy: Perspectives on Platform Power, Public Values and the Potential of Social Media Councils

    Get PDF
    Social media platforms have created private communication orders which they rule through terms of service and algorithmic moderation practices. As their impact on public communication and human rights has grown, different models to increase the role of public interests and values in the design of their rules and their practices has, too. But who should speak for both the users and the public at large? Bodies of experts and/or selected user representatives, usually called Platform Councils of Social Media Councils (SMCs) have gained attention as a potential solution. Examples of Social Media Councils include Meta’s Oversight Board but most platforms companies have so far shied away from installing one. This survey of approaches to increasing the quality of platform decision-making and content governance involving more than 35 researchers from four continents brough to together in regional "research clinics" makes clear that trade-offs have to be carefully balanced. The larger the council, the less effective is its decision-making, even if its legitimacy might be increased. While there is no one-size-fits-all approach, the projects demonstrates that procedures matter, that multistakeholderism is a key concept for effective Social Media Councils, and that incorporating technical expertise and promoting inclusivity are important considerations in their design. As the Digital Services Act becomes effective in 2024, a Social Media Council for Germany’s Digital Services Coordinator (overseeing platforms) can serve as test case and should be closely monitored. Beyond national councils, there is strong case for a commission focused on ensuring human rights online can be modeled after the Venice Commission and can provide expertise and guidelines on policy questions related to platform governance, particularly those that affect public interests like special treatment for public figures, for mass media and algorithmic diversity. The commission can be staffed by a diverse set of experts from selected organizations and institutions established in the platform governance field
