The Usenet is a global computer conferencing system on which users can affix textual messages under 4500 different categories. It currently has approximately 4,165,000 readers, and these .readers have appropriated language by adapting it to the Usenet's culture and medium. This thesis conceptualizes the Usenet community's appropriation of language, provides insights into how media and media restrictions cause their users to appropriate language, and discusses how future media may further cause users to appropriate language. With the Usenet we have a chance to study a relatively new community bound by relatively new technology, and perhaps we can learn more about the appropriation process by studying the two.

A research report submitted to the Faculty of Humanities, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Master of Arts in Journalism and Media Studies, April 2016 / Since 2007, Marie Claire South Africa (SA) — which is a glossy women’s magazine covering fashion and beauty trends, sex, relationships, body image, and celebrity news — has been running a special issue of the print magazine called the “Naked issue”. Each year celebrities pose naked in the special issue to raise awareness for a cause, and in doing so funds in aid of a particular organisation linked to the cause are raised. Marie Claire SA calls this awareness-raising initiative the “Naked Campaign”. For the 2015 Naked Campaign, the magazine had 35 celebrities pose in the nude to raise awareness about sexual violence, in aid of Blow the Whistle (BTW), an anti-rape initiative which supports women and children who are victims of abuse and rape. This research is a case study of Marie Claire SA’s March 2015 Naked Campaign edition, and focuses on the Twitter reactions to this edition. It asks: to what extent did the Twitter reactions to Marie Claire SA’s 2015 Naked Campaign show engagement on the issue of sexual violence and can the use of nudity to attract attention to a social issue result in the kind of engagement that can be said to drive the cause forward? Using content analysis, it examines the tweets generated by the hashtag #MCNaked in the first week of the naked issue going on sale. It categorises the tweets according to gender, comments on nudity, celebrities and sexual violence, as well as the tone of the tweets and the understanding therein of the campaign and cause. The research found that the majority (close to 70%) of the Twitter reactions were supportive of the campaign and the cause. Although over half of the comments focused on the celebrities, over 50% of tweets commented or focused on the issue of sexual violence, a positive outcome for the campaign. Despite the magazine catering mostly for female readers, there was an almost equal number of tweets by males and females, which meant men were also drawn to the discussion started by a media product followed mostly by women, another positive finding for the campaign. However, only a few of the tweets displayed more substantial engagement with the issue of sexual violence, through either sharing statistics or further information, or including anti-sexual violence statements in their tweets. The research suggests that, taken as a whole, the campaign can be considered as an example of social marketing, while also fulfilling the news values in terms of elements of surprise, personalities, power and marketability. / GR2017

Social phenomena have been studied extensively in small scales by social scientists. With the increasing popularity of Web 2.0 and online social networks/media, a large amount of data on social phenomena have become available. In this dissertation we study online social phenomena such as social influence in social networks in various contexts. This dissertation has two major components: 1. Identifying and characterizing online social phenomena 2. Leveraging online social phenomena for economic and commercial purposes. We begin the dissertation by developing multi-level revenue sharing schemes for viral marketing on social networks. Viral marketing leverages social influence among users of the social network. For our proposed models, we develop results on the computational complexity, individual rationality, and potential reach of employing the Shapley value as a revenue sharing scheme. Our results indicate that under the multi-level tree-based propagation model, the Shapley value is a promising scheme for revenue sharing, whereas under other models there are computational or incentive compatibility issues that remain open. We continue with another application of social influence: social advertising. Social advertising is a new paradigm that is utilized by online social networks. Social advertising is based in the premise that social influence can be leveraged to place ads more efficiently. The goal of our work is to understand how social ads can affect click-through rates in social networks. We propose a formal model for social ads in the context of display advertising. In our model, ads are shown to users one after the other. The probability of a user clicking an ad depends on the users who have clicked this ad so far. This information is presented to users as a social cue, thus the click probability is a function of this cue. We introduce the social display optimization problem: suppose an advertiser has a contract with a publisher for showing some number (say B) impressions of an ad. What strategy should the publisher use to show these ads so as to maximize the expected number of clicks? We show hardness results for this problem and in light of the general hardness results, we develop heuristic algorithms and compare them to natural baseline ones. We then study distributed content curation on the Web. In recent years readers have turned to the social web to consume content. In other words, they rely on their social network to curate content for them as opposed to the more traditional way of relying on news editors for this purpose -- this is an implicit consequence of social influence as well. We study how efficient this is for users with limited budgets of attention. We model distributed content curation as a reader-publisher game and show various results. Our results imply that in the complete information setting, when publishers maximize their utility selfishly, distributed content curation reaches an equilibrium which is efficient, that is, the social welfare is a constant factor of that under an optimal centralized curation. Next, we initiate the study of an exchange market problem without money that is a natural generalization of the well-studied kidney exchange problem. From the practical point of view, the problem is motivated by barter websites on the Internet, e.g., swap.com, and u-exchange.com. In this problem, the users of the social network wish to exchange items with each other. A mechanism specifies for each user a set of items that she gives away, and a set of items that she receives. Consider a set of agents where each agent has some items to offer, and wishes to receive some items from other agents. Each agent would like to receive as many items as possible from the items that she wishes, that is, her utility is equal to the number of items that she receives and wishes. However, she will have a large dis-utility if she gives away more items than what she receives, because she considers such a trade to be unfair. To ensure voluntary participation (also known as individual rationality), we require the mechanism to avoid this. We consider different variants of this problem: with and without a constraint on the length of the exchange cycles and show different results including their truthfulness and individual rationality. In the other main component of this thesis, we study and characterize two other social phenomena: 1. friends vs. the crowd and 2. altruism vs. reciprocity in social networks. More specifically, we study how a social network user's actions are influenced by her friends vs. the crowd's opinion. For example, in social rating websites where both ratings from friends and average ratings from everyone is available, we study how similar one's ratings are to each other. In the next part, we aim to analyze the motivations behind users' actions on online social media over an extended period of time. We look specifically at users' likes, comments and favorite markings on their friends' posts and photos. Most theories of why people exhibit prosocial behavior isolate two distinct motivations: Altruism and reciprocity. In our work, we focus on identifying the underlying motivations behind users' prosocial giving on social media. In particular, our goal is to identify if the motivation is altruism or reciprocity. For that purpose, we study two datasets of sequence of users' actions on social media: a dataset of wall posts by users of Facebook.com, and another dataset of favorite markings by users of Flickr.com. We study the sequence of users' actions in these datasets and provide several observations on patterns related to their prosocial giving behavior.

Thesis (MPhil)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: It is widely accepted that the Internet has become a valuable resource for social scientists, not just for the purpose of information exchange; via e-mail, discussion groups and electronic journals, but also as a medium for data collection. Its global nature gives a researcher access to a vast range of individuals located around the world. It also opens up access to difficult to hitherto penetrate study areas, such as sensitive research on deviant behaviour. Further, it is claimed that considerable savings to both research budgets and time frames are made possible with the new technology. It is not surprising, therefore, that a substantial body of research, employing the Internet as the primary means of data collection, already exists. This raises a number of questions as to how the Internet fares as a research tool. Are there any important methodological issues that this new approach raises? Do the traditional research methods suffice? Or are adaptations to existing methods necessary when difficulties are encountered? Does such changes affect the more fundamental question of the research design? These questions are considered in this thesis. To answer them, I consider two different types of empirical research designs. The first,' survey research, is a quantitative, numerical design that traditionally has a high level of control. I consider in detail issues of sampling, including non-response, and questionnaire design. The second design examined, ethnographic research, is qualitative, textual and generally has a low level of researcher control. I address the methods used in cyber ethnography and then discuss the considerable ethical concerns that feature in such research. I conclude that, on the whole, the existing methods can be transferred to Internet research. Indeed, some of the problems faced in traditional research are also considerations in Internet studies and can be overcome by employing similar techniques, such as using incentives to reduce non-response rates. However, a number of new problems emerge, such as the lack of paralinguistic cues, which require adaptations to the existing methods in order to produce results that can be considered valid and reliable. However, I also argue that these necessary adaptations to the methods do not affect the underlying principles found in the research design. / AFRIKAANSE OPSOMMING: Dit word algemeen aanvaar dat die Internet In waardevolle hulpmiddel is vir sosiaalwetenskaplikes; nie net vir die uitruil van inligting deur middel van e-pos, besprekingsforums en elektroniese joernale nie, maar ook as In instrument om inligting te versamel. Die globale aard van die internet gee die navorser toegang to In wye spektrum individue internasionaal. Dit verleen ook toegang tot moeilike navorsingsareas, soos sensitiewe navorsing oor afwykende gedrag. Verder word beweer dat dit aansienlike besparings moontlik kan maak vir beide die navorsingsbegroting en tydraamwerk. Dit is dus nie verbasend dat In substansiële hoeveelheid van navorsing, wat die Internet as die primêre bron van dataversameling gebruik, reeds bestaan nie. Dit laat verskeie vrae ontstaan oor hoe die Internet vaar as In navorsingshulpmiddel. Is daar enige belangrike metodologiese kwessies wat hierdie nuwe metode aanraak? Is die tradisionele metodes voldoende? Of moet daar veranderinge aan die huidige metodes aangebring word wanneer probleme ontstaan? Sal hierdie veranderinge die fundamentele aspekte van navorsingsontwerp beïnvloed? Die vrae saloorweeg word in hierdie tesis. Ek gebruik twee empiriese navorsingsontwerpe om die vrae te beantwoord. Die eerste, steekproefnavorsing, is In kwantitatiewe ontwerp wat tradisioneel In hoë vlak van beheer toon. Ek ondersoek in detail kwessies van steekproewe, insluitend geen respons en vraelysontwerp. Die tweede ontwerp wat ondersoek word, etnografiese navorsing, is kwalitatief, tekstueel en toon in die algemeen In lae vlak van navorser beheer. Ek ondersoek die metodes wat gebruik word in kuberetnografie en bespreek dan die etiese vraagstukke wat hierdie navorsing kenmerk. Ek kom tot die gevolgtrekking dat oor die algemeen die huidige metodes toegepas kan word op Internetnavorsing. Inderdaad kan van die probleme wat ondervind word in tradisionele navorsing ook ondervind word in Internet studies en ook hier kan dit oorkom word deur die gebruik van soortgelyke tegnieke, soos om aansporingsbonusse om geen responskoerse te verminder, hoewel daar nuwe probleme opduik, soos die gebrek aan para-taalkundige wenke. Dit noodsaak veranderinge aan die huidige metodes om resultate te lewer wat geldig en betroubaar is. Ek redeneer egter ook dat hierdie nodige veranderinge aan die metodes nie onderliggende beginsels van navorsingsontwerp verander nie.
