MASTER THESIS in Universal Design of ICT May 2017 MASTER THESIS in Universal Design of ICT May 2017 The Accessibility of Chinese Social Media for People with Visual Impairments – the case of Weibo Zhifeng Liu Department of Computer Science Faculty of Technology, Art and Design Preface and Acknowledgement China is just beginning to pay attention to accessibility. There are 83 million people with disabilities in China, including 13 million people with visual impairments. Weibo is one of the most popular social media. There are 100 million daily active users. Almost every Chinese has his own Weibo account, which showed that Weibo has inevitable influence. It would be meaningful if Weibo is fully accessible, especially for people with visual impairments. Thus, through this project I would like to contribute to the research and practice concerning accessibility in China. Firstly, I would like to thank my supervisor Weiqin Chen for providing important instruction in the project and writing-up process. Secondly, I acknowledge the contribution of Information Accessibility Research Association (IARA) in China and the participants involving in survey and user testing for their support in this project. A research paper “How accessible is Weibo for people with visual impairments” based on this project has been accepted as a full paper by the AAATE 2017 (The Association for the Advancement of Assistive Technology in Europe). 15 May 2017, Oslo Zhifeng Liu 1 Abstract Weibo is one of the most widely used social media in China. It is the Chinese Twitter, which allow users to post 140 Chinese characters. Weibo has 100 million daily active users. People usually use it to get news and share their opinions since Weibo serves as micro-blogging. There are at least 13 million people with visual impairments.If the information on Internet are accessible, they can surf online as people without disabilities.Our survey showed that also people with visual impairments use Weibo to get news and share their minds. Weibo consists of multimedia, such as text, images, videos and audios. As a website with mobile applications, Weibo also has common elements, such as navigation, robustness etc. If these are not fully accessible, they can create barriers for the visually impaired. For instance, no alterative text for non-text content and low colour contrast. There exists research focusing on the accessibility of social media services such as Facebook, twitter etc. These services are not available in China. To our knowledge, there is no previous research concerning the accessibility of Weibo. This project aims to identify the accessibility issues of Weibo for people with visual impairments and provide recommendations for improving accessibility. Three evaluation methods were used in this project, including automatic testing, heuristic testing and user testing. AChecker, AccessLint.com and the WAVE evaluation tool were chosen for automatic testing. People with visual impairments were involved in user testing. Based on the evaluations, we found that the most frequent accessibility issues for the visually impaired included lacking alternative text for non-text content, ambiguous description of buttons and labels, no Hotkey setting, illogical layout and inaccessible web widgets used, disabled resize options and low contrast. Based on the findings, we consider Weibo as not fully accessible for people with visual impairments and made recommendations for improvements, including providing alternative text for non-text content, providing Hotkeys and ARIA tags for easier and efficient keyboard navigation, improving colour contrast and logic page design, providing resize options and context- sensitive support. 2 Table

    DEFENSE WHITE PAPER Message from the Minister of National Defense The year 2010 marked the 60th anniversary of the outbreak of the Korean War. Since the end of the war, the Republic of Korea has made such great strides and its economy now ranks among the 10-plus largest economies in the world. Out of the ashes of the war, it has risen from an aid recipient to a donor nation. Korea’s economic miracle rests on the strength and commitment of the ROK military. However, the threat of war and persistent security concerns remain undiminished on the Korean Peninsula. North Korea is threatening peace with its recent surprise attack against the ROK Ship CheonanDQGLWV¿ULQJRIDUWLOOHU\DW<HRQS\HRQJ Island. The series of illegitimate armed provocations by the North have left a fragile peace on the Korean Peninsula. Transnational and non-military threats coupled with potential conflicts among Northeast Asian countries add another element that further jeopardizes the Korean Peninsula’s security. To handle security threats, the ROK military has instituted its Defense Vision to foster an ‘Advanced Elite Military,’ which will realize the said Vision. As part of the efforts, the ROK military complemented the Defense Reform Basic Plan and has UHYDPSHGLWVZHDSRQSURFXUHPHQWDQGDFTXLVLWLRQV\VWHP,QDGGLWLRQLWKDVUHYDPSHGWKHHGXFDWLRQDOV\VWHPIRURI¿FHUVZKLOH strengthening the current training system by extending the basic training period and by taking other measures. The military has also endeavored to invigorate the defense industry as an exporter so the defense economy may develop as a new growth engine for the entire Korean economy. To reduce any possible inconveniences that Koreans may experience, the military has reformed its defense rules and regulations to ease the standards necessary to designate a Military Installation Protection Zone.

  • The Versatility of Microblogging
    www.spireresearch.com Side Click: The versatility of microblogging Microblogging is well-established globally as a way of keeping in touch with others about events occurring in their lives in real-time. Popular microblogging sites include Twitter in the U.S., Tencent QQ in China and Me2day in South Korea. Twitter has 140 million active users1, while China’s Tencent QQ has a staggering 721 million active user accounts2, ranking only behind Facebook in terms of being the most used social networking service worldwide. Microblogging allows users to combine blogging and instant messaging to post short messages on their profiles3; including small and conversational talk, self-promotion, spam and news 4 . On a deeper level, microblogging has altered the way people consume and generate information – not only democratizing the broadcasting of information but also enabling it to be done in real-time. Connecting to stakeholders There are several benefits to integrating microblogging into a business’s regular stakeholder communication regime. Consumers who “follow” a company’s products or services would be the first to know of any promotions. The company also benefits through obtaining prompt feedback and suggestions for improvement.

  • The Limits of Commercialized Censorship in China
    The Limits of Commercialized Censorship in China Blake Miller∗ September 27, 2018 Abstract Despite massive investment in China's censorship program, internet platforms in China are rife with criticisms of the government and content that seeks to organize opposition to the ruling Communist Party. Past works have attributed this \open- ness" to deliberate government strategy or lack of capacity. Most, however, do not consider the role of private social media companies, to whom the state delegates information controls. I suggest that the apparent incompleteness of censorship is largely a result of principal-agent problems that arise due to misaligned incentives of government principals and private media company agents. Using a custom dataset of annotated leaked documents from a social media company, Sina Weibo, I find that 16% of directives from the government are disobeyed by Sina Weibo and that disobedience is driven by Sina's concerns about censoring more strictly than com- petitor Tencent. I also find that the fragmentation inherent in the Chinese political system exacerbates this principal agent problem. I demonstrate this by retrieving actual censored content from large databases of hundreds of millions of Sina Weibo posts and measuring the performance of Sina Weibo's censorship employees across a range of events. This paper contributes to our understanding of media control in China by uncovering how market competition can lead media companies to push back against state directives and increase space for counterhegemonic discourse. ∗Postdoctoral Fellow, Program in Quantitative Social Science, Dartmouth College, Silsby Hall, Hanover, NH 03755 (E-mail: [email protected]). 1 Introduction Why do scathing criticisms, allegations of government corruption, and content about collective action make it past the censors in China? Past works have theorized that regime strategies or state-society conflicts are the reason for incomplete censorship.

    Statistical Data Mining for Sina Weibo, a Chinese Micro-blog: Sentiment Modelling and Randomness Reduction for Topic Modelling London School of Economics and Political Sciences Wenqian Cheng A thesis submitted to the Department of Statistics of the London School of Economics for the degree of Doctor of Philosophy, London, March 2017 2 Declaration I certify that the thesis I have presented for examination for the MPhil/PhD degree of the London School of Economics and Political Science is solely my own work other than where I have clearly indicated that it is the work of others (in which case the extent of any work carried out jointly by me and any other person is clearly identified in it). The copyright of this thesis rests with the author. Quotation from it is permitted, provided that full acknowledgement is made. This thesis may not be reproduced without my prior written consent. I warrant that this authorisation does not, to the best of my belief, infringe the rights of any third party. I declare that my thesis consists of approximately 50,000 words. 1 Abstract Before the arrival of modern information and communication technology, it was not easy to capture people's thoughts and sentiments; however, the development of statistical data mining techniques and the prevalence of mass social media provide opportunities to capture those trends. Among all types of social media, micro-blogs make use of the word limit of 140 characters to force users to get straight to the point, thus making the posts brief but content-rich resources for investigation.

  • Analysis of Bytedance with a Close Look on Douyin / Tiktok ——————————————————
    —————————————————— Analysis of ByteDance with a close look on Douyin / TikTok —————————————————— Author: Xiaoye SHI Supervisor: Prof. Dr. Didier SORNETTE A thesis submitted to the Department of Management, Technology and Economics (D-MTEC) of the Swiss Federal Institute of Technology Zurich (ETHZ) in partial fulfilment of the requirements for the degree of Master of Science in Management, Technology and Economics June 2019 Acknowledgements I would like to thank my supervisor Prof. Dr. Didier Sornette, who has kindly given me countless guidance and advice throughout the Master thesis. I appreciate the opportunity to work on this interesting topic under the Chair of Entrepreneurial Risks and is deeply grateful for all the help received along the process. I also want to express my deepest gratitude to my parents, who have been supportive and encouraging under all circumstances. Without them, I would not be able to become the person I am today. - 2 - Abstract In 2018, ByteDance, a young Internet company with only 6 years of history, broke out on various news headlines as the highest valued unicorn. With the acquisitions of musical.ly and Flipgram, the company’s flagship product Douyin strikes to develop its global presence under the name TikTok. This thesis analyzed Douyin’s historical growth and revenue model. As a main revenue driver, future user growth is predicted and calibrated by extending the methodology proposed in earlier studies by Cauwels and Sornette. We considered three growth scenarios – base, high and extreme, and estimated Douyin as well as ByteDance’s value based on comparable company analysis. ByteDance’s key performance metrics and multiples were compared with four other firms in the similar industry, Facebook, Weibo, Momo and iQIYI.
