THE ROLE OF PRINT AND SOCIAL MEDIA IN SOCIAL MOVEMENTS: THE CASE OF BRING BACK OUR GIRLS

KAREEM, ABDULAZEEZ MAJEK January 2017 (has links)
AbstractThis thesis critically examines the impact of print and social media in a social movement by using Bring Back Our Girls as a case study, which depicts the abduction of girls by warlords in Africa. Today, due to social inequality, activists do not possess the same budget as larger companies for advertising and mass communications. Social movement campaigners depend on media coverage to gain public attention so that their voice can be heard. This study explores the role of print and social media in a social movement - the case of Bring Back Our Girls in Nigeria. A digital signage prototype was designed and developed to solve the issue of digital divide experienced by the Bring Back Our Girls advocacy group during the campaign. However, the digital signage turns the four stages of conventional social movements, which are Emergence, Coalescence, Bureaucratisation, and Decline. For example, if the movement is on bureaucratisation and a new channel is added, people will go back to emergence stage. This prototype, when fully developed, could be used to create awareness and to reach people in rural areas. This study used two research paths, primary and secondary. Primary research is conducted using two main methods: interviews (focus group interview) and a questionnaire. The focus group consisted of fifteen people, fourteen males and one female, although many female activists were invited, only one attended the meeting because of the socio-economic factor in Nigeria and the focus questions were open-ended. In addition, a questionnaire was designed for the evaluation of the prototype. The focus group interview focused on the examination of the role played by the print and social media platforms during the BBOG campaign and the questionnaire focused on the digital signage. The study also examined how a prototype of digital signage is designed by using the Microsoft PowerPoint Application. Secondary research was conducted using literature, online material, articles, e-books, etc., to gain an in-depth understanding of the role of print media, social media, social movement, design science, prototype design, resource mobilisation theory (RMT), social mobilisation, and digital divide. Specific research methods were identified based on the theoretical perspective chosen by the author. Both quantitative and qualitative data gathered in this study suggest that print and social media have some positive impacts on social movement and some of the participants claimed that they had been informed of Boko Haram’s rampage and the abduction of the Chibok girls through print media, such as newspapers, magazines, roadside posters, and billboards.Moreover, some participants claimed that they became aware of the BBOG campaign through social media like Facebook, Twitter, etc. The focus group interviews led to identification of six key themes. These were, information and intelligence gathering, social and print media education, information sharing, religious or tribal sentiment, communication, and networking and advocacy. Also, there are a number of sub-themes, which are discussed at length within the analysis of the report. The general findings are that the BBOG campaign movement was first noticed on electronic media, but became viral and sporadic in print and social media. Despite the cultural and religious differences in Nigeria, the campaigners came together to solicit for the rescue of the Chibok Girls.

The Linguistic Expectancy Bias and the American Mass Media

Hunt, Alexandrea Melissa January 2011 (has links)
Socially salient information (such as stereotypes and expectancies) can be transmitted amongst individuals in a variety of subtle ways. One of these is the Linguistic Expectancy Bias (LEB), in which patterns of linguistic abstraction indirectly indicate a speaker's attitudes toward a target. The LEB is a common feature of human communication, but research on it has largely been limited to the laboratory; its presence in news media reports is not well-studied. In three studies, I investigate the operation of the LEB in the print media domain. In the first, published reports of NFL games between intercity rivals were analyzed to determine whether or not hometown teams receive more favorable linguistic treatment than hated rivals; results indicate no evidence of a systematic LEB effect. In the second, news reports about the 2004 Presidential election were examined for differential coverage based on the party membership of the candidates, with no evidence of linguistic bias discovered. In the third, participants were exposed to a description of a politician that varies in the levels of abstraction used to describe his actions and asked to form impressions of him. Linguistic bias was found to have a subtly paradoxical effect, such that bias against a candidate resulted in greater explicit and implicit liking for him. Implications for both the social psychology and political science literatures are discussed. / Psychology

The Cultural Life of Extinction in Post-Darwinian Print Culture

Pasquini, Robert 11 1900 (has links)
This thesis is an interdisciplinary study that traces colloquial engagements with extinction in Victorian print culture (1859-1901). Extinction’s broad cultural life demonstrates the extent that scientific and cultural topics intricately entangled within Victorian print networks. Non-specialist Britons absorbed and transmitted evolutionary (particularly, Darwinian) knowledges within public discursive spaces instead of exclusively institutional settings. Class stratification did not bar non-specialists from absorbing and perpetuating cultural conversations about collapses, conservationism, and overconsumption. My project thus seeks to amend the critical discourse that assumes that Victorians passively accepted impending catastrophes or paid scant attention to extinction pressures. I recover multiple subjects formerly hidden in the vast Victorian archives: obscure non-specialists of the working and middle classes, obscurer animals cohabiting the Victorian’s everyday spaces, and the popular (and in some cases, underappreciated) literary texts demonstrating how Victorians circulated extinction discourses. Chapters One and Two explore the non-literary side of print culture, recovering widely disseminated but now largely unknown periodical artifacts (the domain of Punch, The Times, or Funny Folks). Chapter One focuses on cultural reactions to collapses of England’s domestic birds. Chapter Two traces the economized conservationism of the Brooke Brothers, popular game and meat traders. In both chapters, I determine how experienced evolutionary knowledges revealed the human-caused tenuousness of a trans-species milieu. Chapters Three and Four concentrate on scientific romances originally serialized in periodicals, including my key literary case studies, H.G. Wells’s The Time Machine (1895) and M.P. Shiel’s The Purple Cloud (1901). Musing on extinction led to a mindset that acknowledged entanglement with nonhuman others as an ethical imperative. However, some case studies demonstrate a profound ambivalence toward the human’s self-extinction, resulting in a complicated engagement with future forms that often re-privileges the human from within a radical ontology. / Thesis / Doctor of Philosophy (PhD) / This study examines how Victorians absorbed and communicated ideas about extinction, especially as informed by evolutionary theory. Throughout Victorian newspapers, journals, and literature, extinction was adopted for disparate uses. A culturally, economically, and philosophically muddied topic, extinction provoked reconsiderations of the natural world and humankind’s place within it. I begin by examining advertisements, articles, and illustrations from popular newsprint and periodical sources that communicated fears about the extinction of common animals and concerns about controlling or maintaining bird and game populations in everyday Victorian life. When I turn my attention to my literary case studies, H.G. Wells’s The Time Machine and M.P. Shiel’s The Purple Cloud, I analyze the period’s preoccupation with the human’s future forms, looking at both posthuman evolutionary outcomes and the experience of becoming-nonhuman itself. Significantly, this project recovers underappreciated Victorians and texts, filling important gaps in Victorian periodical studies and animal studies.

Formatting variables and typeface variations of dot-matrix print and their effect on reading comprehension and reading speed

Holmes, James A. 03 February 2004 (has links)
The purpose of this study was to determine whether three typeface variations of dot matrix print [single density, dual density, and photocopied dot matrix type] and two formatting variations [fully justified and left justified] had any effect on the reading rates or reading comprehension of college students when compared to the same typewritten material. A pretest/posttest design with experimental and control groups utilized the Cloze Reading Test and the Nelson Denny Reading Test to measure reading comprehension and reading rates respectively to college students [N= 240]. Subjects were randomly assigned to the groups to test the effects of the six treatment levels and two control groups of the independent variables [typefaces and type formatting] on the dependent variables [reading comprehension and reading rates. Four test sessions were used to collect the data and answer the research question: Do either of the three typeface variations of dot matrix print or the two formatting variables have any effect on reading comprehension or reading rates of the subjects when compared to typewriter type? A factorial analysis of covariance [p. < .05] was used to analyze reading comprehension; and a two way analysis of variance [p. < .05] was used to analyze reading rates. The findings indicated that typefaces or formatting made no significant difference in the reading rate or reading comprehension scores of the subjects tested. / Ph. D.

Going digital? : The work processes with e-books at academic libraries in Sweden

Kunzmann, Bert January 2024 (has links)
Research regarding e-book management at academic libraries is scarce, especially referring to Swedish university libraries. The work with e-books regarding selection, acquisition, promotion etc. can give insight into the stance towards e-books and their use at Swedish academic libraries. Challenges and problems such as accessibility, licensing as well as DRM restrictions may hinder e-books from becoming worthy complements to printed books. This thesis gives more insight into the acquisition, work and distribution and general working processes with e-books at Swedish academic libraries. A total of eight Swedish university libraries with 13 representatives agreed to participate in semi-structured interviews. The main results are that selection and acquisition of e-books are both influenced by librarians themselves and by user demand, and that e-books are frequently used and sometimes even favored over print books. Complex licensing and DRM restrictions may lead to e-books not being fully appreciated, which is further complicated due to a lack of promotion of e-books by academic libraries. Academic e-books are offered in English due to a lack of Swedish titles. In some situations, print books are acquired, e.g. if electronic titles are not available or too expensive. Both formats have advantages and disadvantages regarding access, availability, usage and preference. While print books are cheaper and offer a tactile experience, e-books can be read by multiple users simultaneously and do not require storage space in contrast to print books.

Fracture and Friction Characterization of Polymer Interfaces

Vu, Ivan 18 December 2015 (has links)
Understanding the interactions of polymer interfaces is essential to improve polymer-based designs, as the properties of the interface are often different than those of the bulk material. This thesis explores the interfacial interactions of polymer interfaces for two classes of materials, additive manufacturing materials and fiber-reinforced composites. Additive manufacturing (AM) refers to a number of processes which rely on data generated from computer-aided design (CAD) programs to construct components by adding material in a layer-by-layer fashion. AM continues to generate a substantial amount of interest to produce fully functional products while reducing tooling costs associated with traditional manufacturing techniques such as casting and welding. Recent advancements in the field have led to the production of multi-material printing that has the potential to create products with enhanced mechanical properties and additional functionality. This thesis attempts to characterize the fracture resistance of AM materials produced by the PolyJet process. Test standards established for mode I fracture testing of adhesive joints are adapted to evaluate the fracture resistance and interface between two printed acrylic-based photopolymers. Significant differences in fracture energy and loci of failure between the selected test configurations were observed depending on the print orientation. Failures were nominally seen to occur at the interface, alternating from one adherend interface to another in a random fashion. Results demonstrated a decreasing trend in fracture energy at slower crack propagation rates, indicating that such dependency is associated with the fracture resistance of the interface. T-peel tests conducted on specimens prepared with both constant and graded interlayers revealed enhanced peel resistance with gradient interlayers, suggesting design opportunities of enhanced fracture toughness by implementing intricate material patterns at the interface of the two photopolymers. Fiber reinforced composite (FRCs) materials have become increasingly desirable in a number of industrial applications where weight reduction is critical for increased payloads and higher performance. When manufacturing structures from these materials, the presence of friction in the composite forming process is seen to have a major effect on the finished quality. Friction between the plies, or between the composite laminate and forming tool, can be undesirable as shape distortions such as wrinkles can appear and compromise the structural integrity of the finished product. To evaluate these frictional processes, a standard rheometer is used to evaluate tool-ply friction on dry textile fabrics and graphite/epoxy prepregs over a range of temperatures, pressures, and sliding velocities. The results provide some general insights into the frictional response of composite prepregs as a function of the manufacturing environment. The materials tested are shown to have different mechanisms that govern the frictional processes. In particular, the results of friction testing on the prepreg indicate that friction comes from a contribution of both Coulomb and viscous-related mechanisms, the latter which become especially at higher temperatures. / Master of Science

Toward a Computational Historiography of Alchemy: Challenges and Obstacles of Object Detection for Historical Illustrations of Mining, Metallurgy and Distillation in 16th–17th Century Print

Lang, Sarah, Liebl, Bernhard, Burghardt, Manuel 04 July 2024 (has links)
This study explores the use of modern computer vision methods for object detection in historical images extracted from 16th–17th century printed books containing illustrations of distillation, mining, metallurgy, and alchemical apparatus. We found that the transfer of knowledge from contemporary photographic data to historical etchings proves less effective than anticipated, revealing limitations in current methods like visual feature descriptors, pixel segmentation, representation learning, and object detection with YOLOv8. These finddings highlight the stylistic disparities between modern images and early print illustrations, suggesting new research directions for historical image analysis.

Vadå nationell självbild? : En diskursanalys av hur svenskspråkig tryckpress förhåller sig till The Local Sweden:s nyhetsförmedling av Sverige och "det svenska" / What do you mean national self-image? : A discourse analysis of how Swedish-language print media relate to The Local Sweden's news coverage of Sweden and its "essence"

Nilsson, Mimmi January 2016 (has links)
The Bachelor dissertation What do you mean national self-image? is a discourse analysis of the relationship between Swedish news providers. The study aims to investigate how Swedish-language print media interact with the main provider of Swedish news in English, The Local Sweden, and what it reports as the “essence” of the nation and its people.   The investigation has been conducted through the implementation of Ernesto Laclau’s and Chantal Mouffe’s discourse analysis and uses intertextuality, stereotypes, social representation, as well as nationalism and the imagined communities as its theoretical framework. The material selected for the analysis comprises publications by Swedish-language print media from the year of 2014, which engage in a dialogue with The Local Sweden beyond the generic interaction of news. The dissertation concludes that Swedish-language print media approach The Local Sweden’s news coverage in two ways: in agreement or in opposition of what has been reported. When The Local Sweden has published something with the intention of capturing the “essence” of Sweden and its people, they bring attention to the Swede’s hugging culture, their food and souvenirs, as well as their knowledge of language. The results of the study suggest that The Local Sweden manages to provide new information on the subjects, which then leads to Swedish-language print media responding with entire articles dedicated to these topics. The articles convey a sense of fascination and curiosity toward the findings and confirm that The Local Sweden has been correct in their observations. However, when The Local Sweden publishes something with the intention of presenting Swedish news rather than the specific “essence” of it, they find different angles in news stories than what has been covered by Swedish-language print media. The results of the study suggest that by doing so they set themselves apart and provoke Swedish-language print media into responding by incorporating a comment for and/or relating to them as a news provider. The comments convey that Swedish-language print media question The Local Sweden’s validity as a valuable member in covering Swedish news.
