U.S. senators on Twitter : party polarization in 140 characters

Russell, Annelise 17 February 2015 (has links)
The tenor of the Senate no longer relies on traditions of apprenticeship and courtesy. The modern reality is a highly party-polarized institution, encouraging intraparty loyalty and interparty discord. Senators’ behavior on roll-call votes and amendments exhibit this hyper-partisan culture, but that culture extends beyond voting behavior. Members' media activities, including communications with constituents and each other, are equally appealing venues to express excessive partisanship. New media technologies, such as Twitter, are extending this partisan game and punching a ticket for every member of the Senate. Twitter offers a low-cost alternative for members to express malcontent with an opposing party while signaling intra-party party support. In this paper, I tease out the extent to which a member’s party and leadership status affect their likelihood to engage in the partisan discourse that now spans social media. I introduce a unique dataset from the 112th Congress that catalogues six months of senatorial Twitter activity and find that minority party members and party leaders are more likely to name-call and express party loyalty. Twitter may be an alternative agenda space for minority interests that seek to alter the status quo and a public relations platform for party leaders who are tasked with shaping the debate. / text

Fotboll på sociala medier – här för att stanna : En undersökning i hur och varför en läsare väljer sin kanal och vad det innebär för sportjournalistiken / Football in social media – here to stay

Engvall, Fredrik, Sveidquist, Gustav January 2012 (has links)
Through earlier research it has been established that more and more readers are turning to social media in their search for everyday news. In this report we zoom in on news concerning football and try to find out how readers reason in picking their sources, whether it is social, online or traditional media. By interviewing a group of six, all interested in football and active within social media, we have seen that allthough social media is becoming a major influence in news reporting, it does not seem to be competing with traditional online media. Instead the two are offering the readers very different things all together, and theese differences are what we try to show in this report. Our hope is that the research in sport journalism can be translated in to all kinds of areas and be an indication on how journalism and our society is evolving online.

Vi vill få svar på om Twitter fungerar som ett hållbart komplement till den allmänna marknadsföringen hos fastighetsmäklarbyråerna.   Metod                                                Kvalitativa intervjuer med relevanta personer på fastighetsmäklarbyråer, som idag har konton på Twitter, har genomförts för att kunna undersöka och jämföra befintliga och obefintliga strategier för användning av byråernas Twitter-konton. En analys med programvaran Gephi har utförts där pluginet Retweet Monitor kartlägger spridningen av retweets vid en specifik #hashtag. En kvantitativ enkät med syfte att identifiera fastighetsmäklarbyråernas followers, har också genomförts.   Resultat och slutsats                               Denna studie resulterade i att Twitter kan vara ett hållbart komplement till den allmänna marknadsföringen hos fastighetsmäklarbyråer, om kanalen används på rätt sätt. En modell skapades för att kartlägga hur fastighetsmäklarbyråerna kan och använder sig av Twitter.   Förslag på vidare forskning                  Ett intresse skapades under arbetets gång om hur en strategi för fastighetsmäklarbyråer på Twitter kan utformas. Detta kan ses som ett förslag till vidare forskning. Med Gephi och Retweet Monitor finns stora möjligheter till vidare forskning av byråernas Twitter-konton och dess followers.   Uppsatsen bidrag                                   Uppsatsen kartlägger fastighetsmäklarbyråernas aktivitet på Twitter och detta kan ligga till grund vid eventuellt framtagande av en strategi i framtiden.   Nyckelord                                                Twitter, Fastighetsmäklarbyrå, Marknadsföring, Gephi / Title                                                   Twitter – A sustainable supplement to the general marketing of real estate agencies?   Level                                                  Final assignment for Bachelor Degree in Business Administration   Author                                               Lisette Lexell & Johan Wirtz   Supervisor                                         Jonas Kågström   Date                                                   2012 – May   Aim                                                    The purpose of this thesis is to get a clearer view of how real estate agencies using the social netwok Twitter, what their purpose of the usage are and what group of people they turn to. We want to find out whether Twitter works as a substainable complement to the general marketing for real estate agencies.   Method                                              Qualitative interviews with relevant people in real estate agencies, which currently have accounts on Twitter, have been conducted to examine and compare existing and nonexistent strategies for use of the agencies Twitter accounts. An analysis of the software Gephi has been done where the plugin Retweet Monitor charts the spread of retweets at a specific #hashtag. A quantitative survey designed to identify real estate agencies followers, has also been conducted.     Result & Conclusions                             This study resulted in that Twitter can be substainable complement to the general marketing för real estate agencies if the platform is used proberly. We also created a model that maps out how real estate agencies can and make use of Twitter.   Suggestions for future research            An interest was created during the process of how a strategy for real estate agencies on Twitter can be designed. We see this as a proposal for further research. With Gephi and Retweet Monitor, we see great opportunities for further research of the agencies Twitter accounts, and its followers.   Contribution of the thesis                      In this thesis we have identifies the real estate agencies activity on Twitter and this could be the basis for possible establishment of a strategy in the future.   Key words                                               Twitter, Real estate agency, Marketing, Gephi

Detecting Events From Twitter In Real-Time

Zhao, Siqi 16 September 2013 (has links)
Twitter is one of the most popular online social networking sites. It provides a unique and novel venue of publishing: it has over 500 million active users around the globe; tweets are brief, limited to 140 characters, an ideal way for people to publish spontaneously. As a result, Twitter has the short delays in reflecting what its users perceive, compared to other venues such as blogs and product reviews. We design and implement SportSense, which exploits Twitter users as human sensors of the physical world to detect major events in real-time. Using the National Football League (NFL) games as a targeted domain, we report in-depth studies of the delay and trend of tweets, and their dependence on other properties. We present event detection method based on these findings, and demonstrate that it can effectively and accurately extract major game events using open access Twitter data. SportSense has been evolving during the 2010-11 and 2011-12 NFL seasons and it has been collecting hundreds of millions tweets. We provide SportSense API for developers to use our system to create Twitter-enabled applications.

Tweet, tweet, promotionmixens nya kläder : En undersökning till vad Twitter används till, sett utifrån promotionmixen

Andersson, Camilla, Nystrand, Hannah January 2010 (has links)
Twitter används av ett brett spektrum av företag, alltifrån stora bolag såsom Google, till mindre företag såsom lokala caféer. I den här undersökningen ser vi på användningen av Twitter i tre små– och medelstora företag. Promotionmixen användes som plattform, vilken består av reklam, sales promotion, personlig försäljning, public relations och direkt marknadsföring, för att kunna fastställa till vad Twitter används. Syftet är att beskriva och skapa en förståelse för hur Twitter används, med hjälp av promotionmixen. Intervjuer, såväl som innehållsanalys, utfördes. Public relations var det Twitter först och främst användes till, över hälften av alla tweets var av karaktären public relations. De andra delarna av promotionmixen användes också på Twitter, dock var personlig försäljning det minsta användningsområdet. Andra områden hittades även, men promotionmixen var det Twitter användes mest till.

An examination of source credibility and word of mouth best practices for social media marketing with an emphasis on Twitter

Alexander, Lauren Elizabeth 23 July 2012 (has links)
Because social media is a relatively new digital medium and Twitter is an even newer medium, it is important for practitioners and academics to understand how to create and utilize the best messaging strategies to induce persuasion, win brand advocates and create a sustainable, credible presence for brands on social media platforms such as Twitter. The author seeks to examine the theoretical and practical relevance of social media, with an emphasis on Twitter as well as explore how the theories of source credibility and word-of-mouth can help to better understand and measure promotional message and strategy effectiveness. / text

Analysis of Moving Events Using Tweets

Patil, Supritha Basavaraj 02 July 2019 (has links)
The Digital Library Research Laboratory (DLRL) has collected over 3.5 billion tweets on different events for the Coordinated, Behaviorally-Aware Recovery for Transportation and Power Disruptions (CBAR-tpd), the Integrated Digital Event Archiving and Library (IDEAL), and the Global Event Trend Archive Research (GETAR) projects. The tweet collection topics include heart attack, solar eclipse, terrorism, etc. There are several collections on naturally occurring events such as hurricanes, floods, and solar eclipses. Such naturally occurring events are distributed across space and time. It would be beneficial to researchers if we can perform a spatial-temporal analysis to test some hypotheses, and to find any trends that tweets would reveal for such events. I apply an existing algorithm to detect locations from tweets by modifying it to work better with the type of datasets I work with. I use the time captured in tweets and also identify the tense of the sentences in tweets to perform the temporal analysis. I build a rule-based model for obtaining the tense of a tweet. The results from these two algorithms are merged to analyze naturally occurring moving events such as solar eclipses and hurricanes. Using the spatial-temporal information from tweets, I study if tweets can be a relevant source of information in understanding the movement of the event. I create visualizations to compare the actual path of the event with the information extracted by my algorithms. After examining the results from the analysis, I noted that Twitter can be a reliable source to identify places affected by moving events almost immediately. The locations obtained are at a more detailed level than in news-wires. We can also identify the time that an event affected a particular region by date. / Master of Science / News now travels faster on social media than through news channels. Information from social media can help retrieve minute details that might not be emphasized in news. People tend to describe their actions or sentiments in tweets. I aim at studying if such collections of tweets are dependable sources for identifying paths of moving events. In events like hurricanes, using Twitter can help in analyzing people’s reaction to such moving events. These may include actions such as dislocation or emotions during different phases of the event. The results obtained in the experiments concur with the actual path of the events with respect to the regions affected and time. The frequency of tweets increases during event peaks. The number of locations affected that are identified are significantly more than in news wires.
