Due to the rise of social networking, people spend more time on the Internet. They not only make friends and express their emotion in the real life, but also in the virtual world. In the stage of the Internet, which without limit in time and space, we can even perform so that other people can spectacle and join us. Hence, through the IT design functions which social network websites offer, how users can perform or spectacle easily on the social network websites, and what the meaning is about the action-dramas which users have performed. A private blog-Plurk, which we also called micro blog, is using as a field of study. In this thesis, we use Ethnography survey to observe and interview the users. We use Coffman¡¦s Dramaturgical approach as the study framework, and divide it into five parts- Front Stage Style, Team Management, Role Play, Impressions Control and Intimate Relationship to analyze. In the data analysis, we compare IT function design and performing dramas. We will find out what the affordance the IT function can offer, and what the drama will perform. Finally, we will sort out the implications of the management and social capital. From this thesis we can learn: 1. What kind of IT functions offer to users on Plurk? 2. Through these IT functions, what kind of action-dramas will perform? 3. What are the implications and meanings of all these action-dramas? This thesis focus on the performing dramas and IT affordance because of the difference between IT function offer and design, the action-dramas will perform quite different, and the IT affordance will facilitate different key point. Therefore, from this thesis we hope that we can figure out some important functions and reasons that people is willing to stay longer on our website and some instructions for the website designers.

Many studies on social movements aim to understand a moment on an international level. This paper aims to contribute to the understanding of the Swedish environmental movement and the collective identity that can be found in these movements. In an effort to do this, the study aimed to answer research questions. The questions aimed at answering if collective identity is observable on social media, and to what degree, and how the collective identity online compares to what can be seen at a protest on the street. To answer these questions, the author took the help of two qualitative methods. The study looks at collective identity inobservable activities. The netnographic method has been used to gain insight into ten different Facebook pages that belong to seven separate Swedish environmental organisations. The ethnographic method of participant observation has been used to gain insight into six protests that took place in Stockholm, Sweden, during the spring semester of 2022. The results suggest that collective identity is visible online, to a high degree, because all aspects of collective identity are observable. Also, comparing the results between Facebook pages and street protests the visible collective identities did not differ, they just manifested in different ways.

本文嘗試透過社群媒體微博進行憂鬱書寫識別，主要期望回答兩方面的問題：（一）中國憂鬱人群之社群媒體書寫特質為何？（二）如何透過該書寫特質識別更多的憂鬱文本？ 透過對十位已確認之憂鬱症患者之微博關係圈進行滾雪球，發現 127憂鬱傾向者，共爬取憂鬱傾向者之微博文本20748則，作為文本分析之數據集，並運用內容分析、質化分析、詞頻分析及詞語共現等多種方法分析文本。 分析結果顯示：(1)透過對文本進行語調、情緒、主題及憂鬱程度的編碼後，我們發現憂鬱傾向者在微博之書寫含62%的負面語調及25.1%的憂鬱文本，其中，負面及憂鬱程度較高的書寫主題是「自我」、「親情」、「自殺」及「睡眠障礙」。(2)深入對「自我」及「親情」憂鬱書寫的質化分析後，發現他們不同於一般人的心理特質，其中，「自我厭惡」及「不被理解」是他們心中最難以釋懷的角落。(3)由於「自殺」、「睡眠障礙」屬於憂鬱人群特徵，經過分析發現透過主題關聯詞的共現詞組有助於辨識憂鬱人群，其中，「睡眠障礙」共現詞的憂鬱文本辨識度達74%，「自殺」共現詞的憂鬱文本辨識度達34%，未來透過機器的方式，可進一步優化該方法，提升憂鬱文本的辨識度。 / This research aims to answer the following questions:(1)What are the characteristics of micro-blog writing by the depressed tendency people? (2)How to identify the text in social media? Ten Wei-bo users with identified depressed tendency were chosen as starting points of snow-ball searching, and 127 users were located. A total of 20748 messages from this group of the users was collected as the dataset. Multiple methods were applied to analyze the texts: content analysis, qualitative text analysis, word frequency analysis and word co-occurrence. The result indicated that: (1)Through the coding of the text tone, mood, theme and degree of depression, we find out that in micro blog writing, the depressive tendency uses 62% of the negative tone and 25.1% of the blue text. Among them, higher negative and degree of depression of writing subjects are "self", "family", "suicide" and "sleep disorder". (2)Through deep qualitative analysis of "self" and "affection" depressed writing, the "self loathing" and "don't understand" in their mind are the most unforgettable. (3)Because the depressed people have the features of "suicide" and "sleep disorder", through the analysis, we find that through theme related words, it is helpful in the identification of the depression text. Among them, the "sleep disorders" co-occurrence words depressed text identification is up to 74%, and "suicide" co-occurrence words depressed text identification degree is 34 %.In the future, through the computer, we can further optimize the method, and enhance the degree of identification of depression text.

This study investigated the relationship between Chinese young adults' usage of micro-blog and their cultural values. Data was collected from a group-administered survey, which was constituted by 484 students aged from 17 to 30 in variety majors in five colleges in Beijing. Results answered two research questions, indicating that there is a strong relationship between traditional cultural values' changes in Chinese young adults and micro-blog usage. The results also indicated that the more Chinese young adults engaged in micro-blog usage, the more likely they would show distinctive features in both Eastern and Western cultural values. In other words, highly active Chinese micro-blog users have crossed the Eastern and Western cultural boundaries and are developing bicultural identity due to globalization in media environment.

Con el advenimiento de las tecnologías de información y comunicación, Cibercomunicação y la Sociedad Red, hay una necesidad de echar un vistazo a Twitter desde una perspectiva transdisciplinaria, ya que los paradigmas de los estudios de comunicación (a partir de los años 30) hasta ahora desarrollado, apuntan a una visión cartesiana de la comunicación, que tiene una visión reducida, fragmentada y de la realidad compartida. El contexto científico de la post-modernidad, en el que operamos, exige otra comprensión, que no se limita, por ejemplo, para sostener en los estudios de los elementos básicos de la comunicación (emisor, receptor, medio, canal ...), pero cubriendo el análisis de Twitter de una manera más a la realidad. Este punto de vista encuentra apoyo en la construcción teórica propuesta por Edgar Morin. Al analizar el complejo, el perfil de FAS en el blog de micro está diseñado como un auto-eco-organización y el flujo de comunicación es visto como un elemento decisivo en este proceso. En este trabajo se propone estudiar la complejidad de las relaciones sociales existentes en el perfil de Twitter de la Fundación Amazonas Sustentable (FAS). Tiene los siguientes objetivos: desarrollar un marco sobre Cibercultura / Twitter y Teoría del Pensamiento Complejo (Edgar Morin), se relacionan los principios del pensamiento complejo (principio dialógico, recursivo y holográfico) del Sistema Social del Twitter de micro blog de FAS y analizar el sistema social del Twitter de micro-blog de la capital FAS. La investigación toma como procedimientos metodológicos para revisar y observaciones sistemáticas y Twitter interpretativa. Estos procedimientos han permitido la formulación de una propuesta teórica que se basa en los supuestos de los sistemas adaptativos complejos. En el curso de este trabajo tiene el siguiente itinerario: el establecimiento de las premisas que guían a las redes sociales, Capital Social y el pensamiento complejo, la presentación de micro-blog Twitter y sus sistemas desde la perspectiva de los principios de complejidad, incluyendo también su entorno funcional, el ciberespacio. / O Twitter é uma ferramenta de micro blog com caráter híbrido de blog, rede social e mensageiro instantâneo, e, enquanto tal, apresenta especificidades, como a limitação de tamanho para cada atualização, a associação com a mobilidade e a rapidez na comunicação. Com advento das Tecnologias de Comunicação Informação, Cibercomunicação e da Sociedade em Rede, nota-se uma necessidade em vislumbrar o Twitter a partir de uma perspectiva transdisciplinar, pois os paradigmas dos estudos da comunicação (desde a década de 30), até agora desenvolvidos, apontam para uma visão cartesiana da comunicação, que apresenta uma visão reduzida, fragmentária e partilhada da realidade. O contexto científico da Pós-Modernidade, no qual estamos inseridos, requer outra compreensão, que não se limite, por exemplo, a deter-se nos estudos dos elementos básicos da comunicação (emissor, receptor, meio, canal...), mas que contemple a análise do Twitter de uma forma mais próxima da realidade. Essa ótica encontra respaldo no construto teórico proposto por Edgar Morin. Nesse olhar complexo, o perfil da FAS no micro blog é pensado como sistema auto-eco-organizador e o fluxo comunicacional é visto como elemento determinante nesse processo. Neste trabalho propõe-se estudar a Complexidade das relações sociais existentes no perfil do Twitter da Fundação Amazonas Sustentável (FAS). Tem-se como objetivos específicos: elaborar um quadro de referência sobre a Cibercultura/Twitter e Teoria do Pensamento Complexo (Edgar Morin); relacionar os princípios do pensamento complexo (princípio dialógico, recursivo e hologramático) ao Sistema Social do micro blog Twitter da FAS e analisar o sistema social do micro blog Twitter da FAS a partir do Capital Social. A investigação toma como procedimentos metodológicos a revisão de literatura e observações sistêmicas e interpretativas do Twitter. Tais procedimentos permitiram que se formulasse uma proposição teórica que toma como base os pressupostos dos sistemas adaptativos complexos. No percurso deste trabalho tem o seguinte itinerário: estabelecimento das premissas que norteiam redes sociais, Capital Social e o pensamento complexo, apresentação do micro blog Twitter e seus sistemas sob a ótica dos princípios da complexidade, incluindo ainda o seu ambiente funcional, o ciberespaço.
