Full textMedia literacy is touted as a necessary life skill for cultural citizenship, yet as it is generally practiced there is little engagement with sustainability issues. In order to gain insights into why this is the case, this research investigated how media literacy practitioners use metaphors to frame both the role of media education in the world and how it affects green cultural citizenship. This involved analyzing web site documents and teacher resources of seven North American media literacy organizations as well as interviewing nine key practitioners within a bounded system called the media literacy ecosystem. Drawing on an ecocritical framework, I analyzed the discourses of the media literacy ecosystem by using multi-site situational analysis, qualitative media analysis and critical discourse analysis. This research explored how media literacy practitioners participate in meaning-making systems that reproduce pre-existing environmental ideologies. The findings show that media literacy education is grounded in a mechanistic worldview, thereby perpetuating unsustainable cultural practices in education. By problematizing the mechanistic discourses of media literacy education, the aim of this research was to raise awareness and to offer potential solutions for changing the nature of those same discourses. As such, I theorized a model of media literacy that incorporates green cultural citizenship, called ecomedia literacy, and outlined a path forward so that sustainability becomes a priority for media literacy educators.

Full textThe past three years (1987 -1990) have seen an increase in environmental coverage and a widening of the press' interest to include broader environmental issues. This increase raises the question of the way in which the press is presenting environmental issues, since the press could play an important role in the development of environmental awareness among the public. The aim of the study was to identify factors that could be influential in encouraging or discouraging environmental coverage, and the type and extent of coverage. The study identified factors influential in the coverage of three environmental issues, global warming, atmospheric ozone depletion, and the Sappi paper mill effluent spill into Eastern Transvaal rivers (1989), in two South African daily newspapers, The Star and The Citizen. A combination quantitative-qualitative content analysis was undertaken on reports by these newspapers to assess the nature of the news values operating during coverage (to determine what made the issues newsworthy), and the existence of editorial bias toward or against the environment. Interviews were conducted with a small sample of news personnel and individuals active in the Sappi effluent spill issue to contextualise the results of the content analyses. The study method was undertaken within the theoretical frame of newspaper agenda-setting. The results showed that despite differences in editorial bias and source use, the newspapers on the whole displayed the same news values in covering the issues. The main news values operating were a focus on the dangerous and controversial aspects, a preference for 'hard news' events, the relevance of an issue for readers and the activities of elite persons or nations in the issue. This indicated event-orientation by the press, and a tendency to sensationalise environmental issues. Some over-simplification of the full ramifications of the issues, particularly the atmospheric issues, was found to be operating. The implications of these approaches for environmental reporting and the reader's perception of the environment were discussed. Logistical factors (intra- and extra-organisational constraints) were also found to play a part in coverage. A wide range of factors were identified that operate, to a greater or lesser degree at different times, in press coverage of environmental issues. These were : - the newspaper perception of its role in society, - editorial policy, resources of the newspaper, area of distribution, the 'hardness' of news, the complexity of the issue, - the availability of accredited sources, the health of the national economy, international economic trends, the amount and type of other news, 'competitive bind', public awareness of environmental issues, and the role of an environmentally-committed individual in the newspaper organisation.

Full textAs young adults have adopted the use of digital new media technologies, previous scholarly research has predicted a lack of interest by young adults in traditional media, including radio. This waining interest in traditional media by young adults has also been reported in the popular press. An abandonment of radio by young adults could bring about an eventual decline in audience, resulting in adverse economic effects to the broadcast radio industry and related industries, including a decrease in radio revenues, the deflation in the value of radio properties, and potential job loss. This research examined the challenges radio programmers and marketers feel they are having in reaching out to and growing young adult audiences in the face of competition from new media and new media technologies as well as new opportunities for programming and marketing that these new media present. This research surveyed websites and interviewed radio broadcasters in the San Francisco Bay Area who demonstrated success in marketing to young adults in an attempt to ascertain the challenges and new opportunities in reaching and cultivating radio listeners is presented by new media. It was found that these San Francisco Bay Area radio stations are using new media tools to market and program to young adult listeners, and that these tools are key in keeping the radio medium robust.

Full textENGLISH ABSTRACT: It is calculated that the biosphere is worth between $16 and $54 trillion. The environment, however, is constantly under threat of proposed development that focuses on recreational, industrial, commercial and residential developments. The environment is an unobtrusive subject. Members of the public can seldom gain firsthand experience about those activities and actions that influence the environment. Therefore, the public relies heavily on the media to inform them of the general state of the environment. This thesis aims to provide guidelines to journalists who work in the field of environmental reporting. Various models of the communication of science, according to which environmental journalists present their work, are discussed. Sustainable journalism is presented as a solution in the debate between objective and subjective reporting. Environmental journalists have diverse sources to tap in search of credible articles. Attention is given to the specific relationship between the media, scientists and lobby groups. Attention is also given to the process of interviewing sources. Certain issues and activities generate more media attention than others. This is discussed with reference to news subjects, agenda setting and the framing of messages. Attention is given to the issues that make a subject newsworthy, ie risk journalism, local input, human interest, conflict and visual impact.
AFRIKAANSE OPSOMMING: Die waarde van die biosfeer word geskat tussen $16 en $54 triljoen. Die omgewing word daagliks in gedrang gebring deur voorgestelde ontwikkeling wat fokus op ontspanning, industriële, kommersiëleen residensiële uitbreidings. Omdat die omgewing 'n onopvallende ("unobtrusive")onderwerp is, steun die publiek swaar op die media om hulle in te lig oor die belangrikheid en invloed van gebeurtenisse in die omgewing wat hulle nie self kan ervaar nie. Daarom speel omgewingsjoernalistiek 'n baie spesifieke rol in die bewusmaking van die publiek oor aspekte wat die omgewing bedreig of interessant maak. Dit moet ook die publiek aanspoor tot direkte omgewingsvriendelikeaksies. Riglyne word in hierdie verhandeling uiteengesit in 'n poging om tot hulp te wees vir joernaliste wat die omgewing hul belangstellingsveldwil maak. Die verskillende modelle van wetenskaplike kommunikasie, waarvolgens omgewingsjoernaliste hul werk aanbied, word bespreek. Volhoubare joernalistiek word as oplossing aangebied in die debat oor objektiewe en subjektiewe verslaggewing. Die verskillende bronne wat omgewingsjoernaliste kan tap om nuuswaardige artikels te kan skryf, word bespreek. Daar word veral gekyk na die media se verhouding en wisselwerking met wetenskaplikes en drukgroepe. Die proses van onderhoudsvoering word ook bespreek. Die suksesvolle gebruik van nuusonderwerpe, asook agendastelling en die raming van artikels om 'n bepaalde boodskap oor te dra, word bespreek om lig te werp op die vraag waarom sekere omgewingsverwante gebeure meer media-aandag genereer as andere Aandag word gegee aan die faktore wat nuuswaardigheid beïnvloed, soos die onmiddellikheid van nuus, risiko-joernalistiek, plaaslike inhoud, die menslike nuushoek, konflik en beeldmateriaal.
Hodgkins, Frances Clara. "Investigating Social Media for Complexity-Based Simple Rules in a Natural Disaster." Thesis, Grand Canyon University, 2019. http://pqdtopen.proquest.com/#viewpdf?dispub=13812648.
Full textThe purpose of this qualitative, descriptive study was to determine how Simple Rules emerged on the Social Media sites Twitter and YouTube in the context of the 2014 South Napa, California earthquake. The conceptual theory underpinning the study was the Eoyang CDE (containers, differences, and exchanges) model. The overarching research question was How did Simple Rules emerge on the Social Media sites Twitter and YouTube in the context of the 2014 South Napa Valley, California earthquake? The sample consisted of 138,177 microblogging Tweets from Twitter and 10 videos from YouTube. Each data set was investigated using research questions designed after the Eoyang CDE model. The study method was qualitative, and the design descriptive, since the approach was the most appropriate for creating a full description of the phenomenon. A previously collected, big, Social Media data set was used to perform qualitative data analysis. The analysis included descriptive statistics, qualitative content analysis, as well as a thematic analysis based on the conceptual model. A significant finding of this study reveals Simple Rules did emerge on Social Media resulting from multi-agent communication. Practical implications from the findings indicate leaders of disaster recovery efforts should focus Social Media efforts on the platform users, and use short statements shaped like Simple Rules to communicate messages of adaptive change and adaptive support. Finally, recommendations for further research applying complex adaptive systems theory to Social Media data sets may lead to better insights into how network-based systems self-organize in the context of disaster events.

Full textENGLISH ABSTRACT: This study focused on the representation of the University of the North in the national media during the period 1994-1999. A preliminary survey of newspaper reports indicated that during the post 1994 elections period the University had been getting negative coverage from the national media, especially the Mai/&Guardian.This period was also characterized by the intensification of transformation processes and other challenges within tertiary institutions. The aim of the study was to investigate how the national print media portrayed the university during the period 1994-1999 and to find out what role the Media Directorate of the division Development and Public Relations has played in the whole process. Both internal and external factors which had an impact on the representation of the university were also explored. This study is important in the sense that media relations is regarded as a strategic management tool whose purpose is to create mutual understanding between an organization and its internal and external stakeholders - more especially during the period when organisations are facing both internal and external changes. Communication is therefore seen as a central tool which is facilitating the transformation process. Seen against the tendency of the media to concentrate on conflict and events as major news stories - a conflict of interests then emerges. Content analysis was used to analyse newspaper articles (from the Mai/&Guardian and Independent Online/Star) covering the university between the period 1994-1999 and interviews were conducted with respondents who had been chosen purposely or specifically because their activities had a direct bearing on the media situation. The major themes or issues which had been the major focus of the media during the said period were then identified and evaluated in terms of the nature of the portrayal of the university . The study showed that the University of the North had been negatively portrayed in the media and that the absence of a Media Relations Officer, Media Relations Policy and the tendency of the media to focus on conflict as a news value contributed to the negative image of the university. It is hoped that the study will contribute towards the formulation of a media relations policy at the university, the assessment of the pace of and the whole transformation process and will highlight the major challenges facing public relations departments (and specifically the media sections) of historically black institutions in the current political dispensation.
AFRIKAANSE OPSOMMING: Die studie ondersoek die mediadekking van die Universiteit van die Noorde in die pers gedurende die tydperk 1994-1999 landwyd. Voorafgaande oorsig oor koerantberigte het aangedui dat na die 1994 nasionale verkiesings die landwye pers In baie negatiewe beeld van die universiteit geskep het. Die nasion ale koerant Mail &Guardian het veral die Universiteit in In negatiewe lig geplaas. Gedurende hierdie tydperk het tersiere instellings 'n verheweging van transformasie-prosesse, gekoppel met ander uitdagings, ondervind. Die doelwit was om die beeld te ondersoek wat nasionale koerante van die Universiteit geskep het en die rol wat hierin gespeel is deur die Media Direktoraat, In onderafdeling van die Universiteit se Ontwikkelings- en Skakelafdeling. Interne en eksterne faktore wat 'n invloed op hierdie beeld kon he, is ondersoek. Organisasies se verhouding met die pers is 'n strategiese kwessie. 'n Wederkerige verstandhouding met interne en eksterne belanghebbendes is onder meer belangrik veral wanneer organisasies interne en eksterne verandering ondervind. Die pers se neiging om op konfliksituasies en soortgelyke gebeurtenisse te konsentreer, vereis des te meer goeie kommunikasie. Die inhoud van koerantberigte oor die Universiteit wat verskyn het in die Mail&Guardian en Independent Online/Star vanaf 1994 tot 1999 is ontleed. Die hooftemas uit die koerantberigte is ge·identifiseer en geevalueer teen die agtergrond van die beeld wat geskep is van die Universiteit. Daarna is onderhoude uitgevoer met werknemers wie se werk 'n direkte uitwerking het op die perssituasie. Die navorser het bevind dat die pers In slegte beeld van die Universiteit geskep het. Die afwesigheid van In persbeleid en 'n skakelbeampte wat spesifiek met die pers onderhandel, gepaard met die pers se neiging om konflik-situasies as nuus te beskou, het daartoe bygedra. Daar word gehoop dat die studie die bepaling van 'n persbeleid vir die Universiteit van die Noorde sal aanhelp. Verder word gehoop dat die Universiteit se benadering tot die transformasiesproses, asook die pas waarop dit plaasvind, geevalueer sal word. Laastens word gehoop dat dit die vernaamste uitdagings wat skakelafdelings (veral die pers-afdelings) van historiese swart instellings in die huidige politiek bedeling in die gesig staar, sal beklemtoon.

Full textThe present study analyzes how EPTV (Emissoras Pioneiras de Televisão - Pioneer Broadcasting Television Stations) selects, deals with and discloses environmental information related to water through its daily news program, the Jornal Regional (JR). Starting from the acknowledgment of television as an important mass media, which implants and promotes ideologies along its viewers, the intention was to study water messages and representations on JR in the region of Campinas, State of São Paulo, where the program is the audience leader in the genre TV news. In this region, today's model of development promotes high demographic, urban and industrial concentration and, subsequently, one of the lowest indexes of hydric availability per capita and water quality in Brazil. Three consecutive months of JR's programming were monitored, selecting for quantitative and qualitative analysis reports with references to water. An interview with the Press Manager of that broadcasting station was conducted on the news production process of JR. Bibliographic studies revealed a commercial and ideological relationship between Rede Globo (Major Broadcasting Station that EPTV rebroadcasts to the region) and EPTV, contextualizing a commercial relationship, which is subject to the interests of the economical and political elite. In such a context, EPTV creates a representation of reality, which is a form of systematic distortion by which viewers see an objective world through a "filter" that promotes or omits facts in an arbitrary fashion. In this scenario, water is regarded as merchandise on JR's messages, being its availability a result of resources management and disconnected from its natural conditions and environmental role. Environmental issues that degrade quality and limit water availability in the region are attributed to domestic consumption and sewage production. Municipal public administrations are appointed as responsible for the reversal of this situation by means of sewage treatment. Water is also associated to an image of environment which is represented as ‘natural landscape’ in a spectacle perspective for the entertainment of viewers.

Full textThe study of turbulence induced mass transfer at the interface between a gas and a liquid is of great interest in many environmental phenomena and industrial processes. Even though this issue has already been studied for several decades, its understanding is still not good enough to create realistic models (RANS or sub-grid LES), especially when considering a liquid phase with a complex rheology. This experimental work aims at studying fundamental aspects of turbulent mass transfer at a flat interface between carbon dioxide and a Newtonian or non-Newtonian liquid, stirred by homogeneous and quasi isotropic turbulence. Non-Newtonian fluids studied are aqueous solutions of a model polymer, Xanthan gum (XG), at various concentrations, showing viscoelastic and shear-thinning properties. Optical techniques for the acquisition of the liquid phase velocity field (Stereoscopic Particle Image Velocimetry, SPIV) and dissolved gas concentration field (Inhibited Planar Laser Induced Fluorescence, I-PLIF) are for the first time coupled, keeping a high spatial resolution, to access velocity and concentration statistics in the first few millimetres under the interface. A new version of I-PLIF is developed. It is designed to be more efficient for near surface measurements, but its use can be generalized to other single or multiphase mass transfer situations. Bottom shear turbulence in the liquid phase is generated by an oscillating grid apparatus. The mechanisms of turbulence production and the characteristics of oscillating grid turbulence (OGT) are studied. The importance of the oscillatory component of turbulence is discussed. A mean flow enhancement effect upon polymer addition is evidenced. The mechanisms of turbulent mass transfer at a flat interface are finally observed in water and low concentration polymer solutions. A conditional analysis of turbulent mass fluxes allows to distinguish the type of events contributing to mass transfer and discuss their respective impact in water and polymer solutions

Full textThe fact that the media is involved and creates the public's perception of reality is perhaps nothing you think of daily. Based on their design, the mass media has a great power to influence how the public interprets different social phenomena. The aim of this study was to find which framing the media creates by the social workers' work environment and its effects. As well as which image media conveys to the public. The study's questions intended to examine how the social workers' work environment was presented, what conditions that emerged were linked to the work environment and which participants were to be heard in articles. To achieve our results, a framing analysis was carried out, by framing how the journalists strategically, consciously or unknowingly, produced what they want to convey. To our help in the analysis work, the framing theory was used to be able to find out how the media portray and produce the social workers' work environment and its effects. The 15 analyzed newspaper articles used for the study were published between 2014–2019. There were no particularly large differences in how the journalists described the social workers' working conditions between the time span examined. It emerged, among other things, that the social service as a workplace is presented as an unhealthy workplace and that social workers flee due to heavy work demands and because of a work environment characterized by threats and violence. The frames that emerged clearly in the study were general frames. Which are formed by a media logic that the journalists themselves created, that is, based on news editorial values, practices and routines. The significance of how the different frames influence is discussed in the study as well as what effects the various participants that may come to speak has influence on the public.
