Testo completoAbstract (sommario):
The aim of this project is to study the level of paradigm development in the domain of social media studies. Based on the works of Kuhn (1970), Pfeffer (1993), and Thompson and Tuden (1959), the level of paradigm development was defined as the degree of consensus regarding: research topics, methods, and theories used in a given field of study. A sample of social media research articles was studied to analyze the level paradigm development within this domain of study. The sample consisted of a group of social media research articles that were published in the top ten journals of communication studies in the last five years. Content analysis methodology was used to analyze the research articles and clusters analysis was utilized in order to investigate the level of paradigm development in this field of study. The analysis confirmed the lack of consensus in the social sciences (Pfeffer, 1993). The level of agreement regarding research methods, theoretical concepts, and research topics used in social media studies was quite low. The lack of consensus in this new domain of study may be explained by two factors. Social media as an academic field is still in its infancy (Van Osch and Coursaris, 2014), and thus it lacks of a shared body of theoretical knowledge that can be used to analyze the phenomenon of social media (Van Osch and Coursaris, 2014; Chong and Xie, 2011; and Khang, Ki, and Ye, 2012). In conclusion, this project suggests that social media studies should aim to develop a high level of paradigm development, since academic fields with high levels of consensus are better organized, have fewer power conflicts, and get more funding (Beyer and Lodhl, 1976; Pfeffer, 1993).

Thesis: Ph. D., Massachusetts Institute of Technology, Department of Physics, 2015.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (pages 69-76).<br>Many biological systems need to control transport of nutrients and ventilation. Unlike many nonliving porous media, they modify themselves to meet these demands; they are active. Using a combination of experiment, theory, and computation, we investigate several living porous media. First we consider termite mounds, meter-sized structures built by insects nearly three orders of magnitude smaller than the mounds themselves. It is widely accepted that the purpose of these mounds is to give the colony a controlled microhabitat that buffers the organisms from strong environmental fluctuations while allowing them to exchange energy and matter with the outside world. However, previous work toward understanding their functions has led to conflicting models of ventilation mechanisms and little direct evidence to distinguish them. By directly measuring air flows inside mounds of the Indian termite Odontotermes obesus, we show that they use diurnal ambient temperature oscillations to drive cyclic flows inside the mound. These cyclic flows in the mound flush out CO2 from the nest and ventilate the colony, in a novel example of deriving useful work from thermal oscillations. We also observe the same diurnally-driven flows in mounds of the African termite Macrotermes michaelseni, evidence that this is likely a general mechanism. We then consider the problem of honeybee swarming, wherein thousands of bees cling onto each other to form a dense cluster that may be exposed to the environment for several days. During this period, the cluster has the ability to maintain its core temperature actively without a central controller. We suggest that the swarm cluster is akin to an active porous structure whose functional requirement is to adjust to outside conditions by varying its porosity to control its core temperature. Using a continuum model that takes the form of a set of advection-diffusion equations for heat transfer in a mobile porous medium, we show that the equalization of an effective "behavioral pressure", which propagates information about the ambient temperature through variations in density, leads to effective thermoregulation. Our model extends and generalizes previous models by focusing the question of mechanism on the form and role of the behavioral pressure, and allows us to explain the vertical asymmetry of the cluster (as a consequence of buoyancy driven flows), the ability of the cluster to overpack at low ambient temperatures without breaking up at high ambient temperatures, and the relative insensitivity to large variations in the ambient temperature. Our theory also makes testable hypotheses for the response of the cluster to external temperature inhomogeneities, and suggests strategies for biomimetic thermoregulation. Finally, we consider a generic model of an active porous medium where the conductance of the medium is modified by the flow and in turn modifies the flow, so that the classical linear laws relating current and resistance are modified over time as the system itself evolves. This feedback coupling is quantified in terms of two parameters that characterize the way in which addition or removal of matter follows a simple local (or non-local) feedback rule corresponding to either flow-seeking or flow-avoiding behavior. Using numerical simulations and a continuum mean field theory, we show that flow-avoiding feedback causes an initially uniform system to become strongly heterogeneous via a tunneling (channel-building) phase separation; flow-seeking feedback leads to an immuring(wall-building) phase separation. Our results provide a qualitative explanation for the patterning of active conducting media in natural systems, while suggesting ways to realize complex architectures using simple rules in engineered systems.<br>by Samuel Alan Ocko.<br>Ph.

La mise en place, l'étalonnage et l'utilisation d'un nouveau banc expérimental basses températures basé sur une technique photothermique appelée photo pyroélectricité (PPE) sont décrits dans ce manuscrit. Les échantillons que nous avons étudiés en utilisant ce nouvel instrument sont le glycérol, le 1,2 propanediol et leurs mélanges binaires avec l'eau. Ce sont des cryoprotecteurs bien connus (CPAs) utilisés dans la cryoconservation, qui est une technique de préservation des cellules et tissus vivants en les refroidissant à des très basses températures. Le but ultime de la cryoconservation est d'éviter ou de maîtriser la formation de glace et d'atteindre un état vitreux ou amorphe. La vitesse de refroidissement, de chauffage et la concentration des CPAs utilisés sont les paramètres clés qui déterminent la formation de la glace. Par conséquent, l'étude des propriétés thermiques, en particulier près de la transition vitreuse (Tg) des solutions binaires des CPAs avec de l'eau est très importante pour comprendre leur comportement lors du refroidissement. La PPE a été utilisée pour étudier l'effusivité et le temps de relaxation ∝ caractéristique de la transition vitreuse. Le Tg et la fragilité (m) ont été déterminés à partir des données de la PPE en utilisant le modèle d'Havriliak Negami. L'état vitreux présente une très grande viscosité, de l'ordre de 10¹² Pa.s au voisinage du Tg. Le Tg et m peuvent être calculés à partir de l'évolution de la viscosité en fonction de la température ou par calorimétrie différentielle à balayage (DSC). Ainsi, des études à l'aide de ces deux techniques ont été menées et les résultats ont été comparés avec les données de la PPE<br>The construction, calibration and application of a new low temperature instrument based on a photothermal technique called photo pyroelectricity (PPE) is described in this manuscript. The samples we studied using the new PPE instrument were glycerol, 1,2 propanediol and their binary mixtures with water. These liquids are well known cryoprotectants (CPAs) used in cryopreservation, which is a technique to preserve the living cells and tissues from biological degradation by cooling to sub zero temperatures. The ultimate goal in cryopreservation is to avoid or control the ice formation and attain a glassy or amorphous state.The rate of cooling and heating and the concentration of the CPAs used are the key parameters that determine the ice formation. Therefore, studying the temperature dependent thermal properties especially near their glass transition temperature (Tg) of the binary solutions of CPAs with water at different concentrations are highly important to understand their behavior while cooling. The PPE technique was used to study the effusity and the ∝ relaxation time near the glass transition phenomenon. The Tg and fragility (m) were determined from the PPE data using the Havriliak Negami model. The glassy state has a characteristic property of very high viscosity, of the order of 10¹² Pa.s at Tg. The Tg and m can be calculated from the temperature evolution of viscosity or from Differential Scanning Calorimetry (DSC) measurements. Therefore, viscosity and DSC studies were conducted on the samples and were compared with PPE data

Testo completoAbstract (sommario):
The Internet’s liberative qualities have been hyped by a number of Zimbabwean scholars who argue, on the basis of the existence of online alternative media that carries political content, that democratisation can be technology-led. Given that the question of source selection is connected to the democratising potential of the Internet (Lecheler and Kruikemeier, 2016) by some scholars – this study interrogated the liberative potential of the Internet by tracing the social media sourcing patterns of four daily newspapers within Zimbabwe’s polarised mainstream media. Using a mixed methods approach which deployed Actor-Network theory as a preliminary methodological tool, this study collected and evaluated empirical data drawn from 146 social media sourced political stories published over a 30-month period and the responses from semi-structured interviews with purposively sampled participants – to account for the human and non-human actors in the news production network. A social constructivist analytical lens was then used to appreciate the contexts in which social media sourcing was being adopted in newsrooms, which revealed how unique circumstances had triggered unprecedented reliance on social media as a political news source. Those unique circumstances involved an escalation of factional fighting within the ruling ZANU PF that morphed into a propaganda war, which was waged through The Herald newspaper by one faction and through social media by the other faction. The public feud, which played out on social media, forced political reporters to gather story ideas from social media and overly rely on a few tech savvy elite sources. In these circumstances, social media’s influence on the political news agenda was overstated as it was conflated with the influence of a news event (ZANU PF factionalism) and the influence of social media users (high-ranking ZANU PF members) who could not be ignored. It is hoped that the findings of this study will contribute towards filling the lacuna in terms of scholarship demonstrating the influence of social media within Zimbabwe’s political narratives.

Testo completoAbstract (sommario):
A highly sensitive transverse susceptometer has been developed for the investigation of magnetic recording media. The susceptometer was based on the design of Pareti and Turilli[4] with modifications to the solenoid and sensing coils. The modifications have resulted in an improvement in the signal to baseline ratio of a factor of 525, and a reduction in random noise. The increase in the sensitivity of the susceptometer allowed the investigation of Advanced Metal Particle (AMP) tapes and the measurement of the imaginary component of the transverse susceptibility (TS) proposed by Papusoi[5]. Also, a modification was developed which allowed the investigation of the non-linear TS, proposed by Chantrell et al[7]. The work reported for the latter two techniques was the first experimental demonstration of these measurements on magnetic recording media. Samples of Co-y-Fe203, Cr02, mixed y-Fe203 / Cr02 and AMP tapes were investigated, as were y- Fe201, Cr0 2 and AMP powders. The investigations suggested that the incoherent reversal mode was dominant in the systems containing Cr02, with coherent reversal dominant in the remaining systems. The anisotropy peaks measured using the non-linear IS were found to be less dependent on sample texture than those of the traditional linear measurement. In particular the anisotropy peaks of the non-linear TS for incoherently reversing systems appeared to be independent of texture and it was proposed that these were a direct measure of the anisotropy field distribution, although independent verification was not performed. The determination of magnetic coating thickness after Sollis and Bissell[6] was extended to allow the measurement of AMP tapes. A computer model was developed to investigate the error in the technique due to the particulate nature of the coating. The results of the model indicated that the error increased as coating thickness and volume packing fraction decreased. Correction factors were determined for MP3 and MP4 particle based systems. The detection of the imaginary component of TS and its close agreement with the theoretical predictions of Papusoi suggested that the dassification of TS as a 'stiffness' method of anisotropy field determination might be in error.

La thèse est consacrée à l'étude des ondes acoustiques et des écoulements à plusieurs phases en milieux poreux. Pour la simulation des écoulements, la méthode de Boltzmann sur réseau a été choisie. On utilise cette méthode pour simuler des écoulements à plusieurs phases ainsi que des ondes acoustiques dans un fluide. Cette méthode représente une approche alternative à la description du mouvement de fluide basée sur la théorie cinétique des gaz. Pour simuler les ondes acoustiques en solide élastique, le modèle LSM (Lattice spring model) a été choisi. Dans le cadre du LSM, le milieu solide est remplacé par un réseau cubique. Les noeuds de réseau sont liés par des ressorts de deux types. Les équations dynamiques obtenues correspondent à celles de la théorie élastique. La méthode a été appliquée pour calculer les célérités des ondes de compression et de cisaillement dans des milieux poreux reconstruits pour différentes fréquences et différentes valeurs de porosité. Les deux modèles (LBM et LSM) ont été couplés par les conditions aux limites pour l'étude des ondes acoustiques en milieu poreux saturé de liquide. Il existe deux approches principales pour simuler des ondes acoustiques en milieu poreux saturé de liquide en utilisant notre modèle (LBM+LSM).

In order to simulate acoustic waves in an elastic solid, the LSM (Lattice Spring model) is selected. In the framework of the LSM, the medium is replaced by a cubic lattice. The nodes of the lattice are connected by springs of two types. The obtained dynamic equations correspond to those of the theory of elasticity. The method is applied to calculate the compressional and shear wave velocities in reconstructed porous media for various frequencies and porosity values. The two models (LBM and LSM) are coupled by the boundary conditions in order to study acoustic waves in saturated porous media. Two principal approaches exist to simulate acoustic waves in saturated porous media using our coupled (LBM+LSM) model. The first is based on the homogenization theory and the second on the real time simulation of acoustic waves. The two methods are applied for calculation of the acoustic waves velocities in saturated reconstructed porous media. The results are systematically analysed. The codes are parallelized by using OpenMP in order to reduce significantly the program run time

Cerca il testo completoAbstract (sommario):
This thesis describes a research project which investigated the use of Media Studies in Values Education at a Catholic Primary School in Brisbane.
The focus of the study was a nine week unit on "Multiculturalism" which utilised the concepts and strategies of Media Studies and which involved the researcher in actually leading the teaching of the unit to a combined class of 55 students from Years 6 and 7.
Teachings for the unit revolved around Construction and Deconstruction activities with particular attention given to the following ethnic groupings:
(i) Anglo/Celtic
(ii) Aboriginal
(iii) Vietnamese
(iv) El Salvadorean
The study developed around the hypothesis that Media Studies can provide a useful means for teaching Values Education and it investigated the following research questions:
1. To what extent did the children have more positive values about themselves and other ethnic groups at the end of the unit on "Multiculturalism"?
2. To what extent was the Media Studies approach to the teaching of the unit responsible for such changes in values that occurred?
3. How did the techniques of Construction and Deconstruction contribute to the development of more positive attitudes to self and others and the ability to interact more effectively with others?
The findings show that Media Studies can, indeed, contribute to the development of core understandings and skills of Values Education as identified by Hill (1991, p. 10) in his "minimum specifications for Values Education in Australia", as follows:
"To assist students:
(a) to acquire a representative knowledge base concerning the value traditions of groups within contemporary Australian society;
(b) to enter with empathy into the perceptions and feelings of people who have been strongly committed to these traditions;
( c) to develop skills of critical and appreciative values appraisal;
( d) to encourage and put into practice skills of decision-making and value negotiation;
( e) to develop a concern for the community and the care of its members.
Both quantitative and qualitative research methodologies were used to chart the development of cognitive, affective and volitional aspects of children's values towards
themselves and other ethnic groups and to examine the development of their interpersonal skills.
The combined findings from the quantitative and qualitative data collected during the study, show that there is a strong case to support the hypothesis that Media Studies
can provide a useful means for teaching Values Education in the classroom. The evidence suggests that by the end of the unit, the children who were involved did have more positive attitudes towards themselves and others, and had improved their interpersonal skills. There is also sufficient evidence to conclude that these outcomes were produced, at least to some significant extent, by the use of the concepts and strategies of Media Studies, particularly Construction and Deconstruction.
The methodologies included a Pre-Test/Post-Test which involved short written responses, drawings and the completion of a ratings scale, as well as interviews,
observations and content analysis of some of the children's video work completed towards the end of the unit.
The use of a variety of methodologies to examine the hypothesis provided the multiple perspectives of triangulation and the opportunity to offset the shortcomings of one type of methodology with another which did not have those potential sources of experimental error. For example, the anonymity of the children's responses in the PreTest/Post-Test helped to ensure that the children would feel free to give their honest responses to the questions and provided an opportunity to cross-check responses given in the interviews.
The study's findings have important implications for teaching and learning and give rise to a number of interesting questions relating to ways children may be assisted to define and refine their ethical positions. It also highlights the problems of encouraging collaborative behaviours within an essentially, individually-competitive school system; and raises issues with respect to the handling of controversial topics by teachers within schools.
Finally, the study suggests the basis for a conceptual framework for using Media Studies to implement Values Education within the classroom and identifies areas for further research.

Bodi, Anna E. "Patty Hearst: A Media Heiress Caught in Media Spectacle." Scholarship @ Claremont, 2013. http://scholarship.claremont.edu/cmc_theses/639.
Testo completoAbstract (sommario):
In 1974, decades before foreign terrorists became a fixture in the American consciousness, the Symbionese Liberation Army (SLA), an American domestic terrorist group, abducted nineteen-year-old media heiress Patricia (Patty) Hearst. The abduction kicked off a four decade multi-faceted media spectacle. The media and public raptly followed Hearst’s imprisonment as a hostage, apparent conversion to SLA revolutionary and criminal, eventual rescue and arrest, trial and conviction, presidential pardon, marriage to her bodyguard, half-hearted career as an actress, and ultimate withdrawal from the public eye. Along the way, the media portrayal of Hearst twisted and turned. She was the heiress, the hostage, the criminal, the victim, depending on the moment in time. The varying depictions of Hearst reflected evolving events, but also specific images of Hearst that captured the attention of the American public and the media. Resonant images of Hearst from her kidnapping, arrest, trial, and release – spanning the five years from 1974 to 1979 – demonstrate that the heiress’s case became a magnification of American anxieties of the time concerning celebrity, feminism and gender, the radicalization of youth, and terrorism. In a time dominated by print, radio, and television media, Hearst’s portrayal showcased the media spectacle as cultural parable for a controversial time.

This study delves into the implicit contract that is formed between the purveyor of an entertainment property and their audience, as well as the consequences of frustrating audience expectations. Building on this model of the implicit contract, the creation of expectations through marketing, character and world development, and the invocation of genre discourses are examined through the lens of the television shows House M.D. and Veronica Mars. The issues surrounding the dynamic equilibrium between novelty and stability in serial entertainment and entertainment franchises brought up by these initial case studies are examined in further detail through the collectible card game Magic: the Gathering, and the complexity of the interactions between different types of expectations are demonstrated via a study of the superhero comics serials 52 and Civil War.<br>by Alexander Chance Austin.<br>S.M.

Testo completoAbstract (sommario):
All over the western world, media are giving Muslims the role as scapegoats for everything that is wrong with society. Through grave generalizations as well as alleged connections between Islam and terrorism, social categorizations are established in which Muslims become the ‘others’. Research has been made on a various amount of western nations, with the exception of a few, and this thesis explores how Argentinean media portray Islam and Muslims. With the use of quantitative and qualitative text analyses, the result will show the levels of priming and framing in relation to earlier research. By assuming social constructivism, a high frequency of these two ‘faces of power’ would affect societal relations, possibly creating a gap between an ‘us’ and ‘them’. Our findings suggest, however, this is not the case in Argentina; on the contrary, Argentinean media lack the frames which make Muslims ‘others’. This important discovery implies that the relationship between Islam and the West of today does not necessarily have to be one of two combatants, incapable of coexisting.

Testo completoAbstract (sommario):
The thesis explores aspects of language in the modern media of communication, with particular reference to its role in the production and circulation of ideologies (Ideologies are understood in this context as systems of representation whose effect is to sustain relations of domination). Investigation is conducted by means of case studies on a variety of media texts ranging from print Journalism through to TV and radio. These case studies suggest that ideology in text may be analysed using various techniques from linguistics, including - for example - the analysis of vocabulary, and the analysis of grammatical systems such as transitivity. But the case studies also suggest that ideologies operate in the form of implicit background assumptions which may be made analytically explicit by drawing upon recent developments in linguistic pragmatics. In addition to engaging with issues of language and ideology in the study of media texts, the case studies are also concerned with the ways in which such texts shape up to their audiences, particularly through the adoption of modes of direct address. Direct address is. considered to be an important indicator of genres in media discourse; and the thesis includes a detailed study of a one particular genre from popular day-time radio. The research is thus seen as occupying a middle ground between linguistics and media studies. It begins with media discourse as projecting dominant forms of common sense but it concludes with issues concerning the relation of these discourses to their putative audiences.

McConochie, Shaun Robert. "Magnetisation reversal studies of particulate recording media." Thesis, University of Central Lancashire, 1998. http://clok.uclan.ac.uk/7715/.
Testo completoAbstract (sommario):
Both an experimental investigation of the interaction effects within commercial particulate recording media and a numerical investigation of the reversal mechanism of particles within the media have been made. The particle systems investigated comprised three audio y-Fe203 tapes, three audio Cr02 tapes and a video metal particle tape. An absolute measure of the interaction effects within particulate tapes has been investigated by comparing the measured properties of isolated particles taken from the medium with the measured bulk properties of the medium. The results indicated negative interactions for all the samples investigated except the video metal particle tape, which indicated positive interactions. However, Al plots for all the samples however, indicated negative interactions. This is contrary to the absolute interactions measured in the video metal particle tape. A possible explanation for this inconsistency was the presence of highly localised alignment of particles, "a chaining effect", within the metal particle system. This effect allows for increased system coercivity without removing the general negative interactions characteristic of all acicular particulate media. A micromagnetic model was developed to study typical y-Fe203 and Cr02 particles measured experimentally in this study. Simulations were performed as a function of the applied field angle and the results compared to the experimental study. The simulations representing typical 'y-Fe203 particles indicated reasonable agreement at the lower applied field angles, while poorer agreement was observed at larger applied field angles. The simulations representing a typical Cr02 particle indicated reasonable agreement at the higher applied field angles, while poorer agreement was observed at low applied field angles. These inconsistencies for both types of particles investigated were accounted for by assumptions and simplifications within the model, particularly the absence of bulk crystalline imperfections, the degree of surface irregularities and the effect of an oversimplified particle shape. The micromagnetic model developed was also used to investigate the effect of model parameters on the reversal mechanism of the 'y-Fe203 particle simulation. It was found that the reversal mechanism was very sensitive to the size and shape of the model particle.

Vopsaroiu, Marian. "Anisotropy and texture studies in magnetic media." Thesis, University of Central Lancashire, 2002. http://clok.uclan.ac.uk/20302/.
Testo completoAbstract (sommario):
The rapid development of magnetic materials for recording media applications increased the demands for new and more precise experimental investigation techniques. In respect with these demands, this project is focused on experimental analyses of advanced particulate media and magnetic thin film samples. A new extended rotational remanence technique for anisotropy field measurements was developed. The technique is suitable for samples that contain aligned or partially aligned particles and provides both: in-plane anisotropy field distributions and the in-plane anisotropy field. This technique was also extended to out-of-plane anisotropy field measurements. Rotational hysteresis was introduced as an alternative method for anisotropy field measurements. This applies well in the case of samples without texture or samples having very small magnetic moment (i.e. thin films). The two techniques for anisotropy field measurement compare well and the experimental results were interpreted in terms of inter-particles interactions. Two measurement methods for determination of the demagnetizing field acting perpendicular to a sample plane were also developed. The first method is based on the in-plane and out-of-plane anisotropy field determination using an extended rotational remanence technique. The second method can provide the demagnetizing field starting from in-plane and out-of-plane transverse hysteresis loops. Comparison between the results from the two methods showed good agreement. Furthermore, the demagnetizing field values were used to calculate the magnetic coating thickness, so the two methods provide a non-destructive method for magnetic thickness measurements in film samples. The in-plane easy axis distribution (EAD) was experimentally determined using vector VSM techniques. Correlations between in-plane tape texture and magnetic thickness were obtained for a series of advanced MP tapes. A theoretical approach was used in order to relate the orientation ratio to EAD. The out-of-plane EAD was derived from numerical calculations. The out-of-plane distribution also showed a variation with the magnetic thickness. In addition, the microstructure and particle morphology of the advanced MP tapes, as well as the out-of-plane component of magnetization, have been investigated using Mossbauer Spectroscopy. Finally, 3D - EAD maps were produced. All VSM experiments were fully computer controlled and the routines were designed in the LabView environment as part of this project.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Comparative Media Studies, 2013.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 94-99).<br>My thesis discusses the hidden and non-adversarial nature of resistance in authoritarian countries through the perspectives of media practices and media opportunity structure. To understand the art of resistance in authoritarian countries, one has to look beyond the striking physical confrontational aspect of resistance. I approach the topic of hidden resistance by examining the social and cultural implications of media artifacts appropriated by movement participants and their strategic interactions with different stakeholders within the media ecosystem. Using media practices and the media opportunity structure as analytical lenses, I conduct case studies on three movements. The first case, Wukan Protest in 2011, which was a local protest against land expropriation, illustrates the essence of non-adversarial resistance in a confrontational incident. Wukan protesters' media practices helped them take advantage of the opportunity structure. The second case examines how New Workers Art Group (NWAG), a nonprofit organization in Beijing, actively produces alternative discourses as resistance to hegemonic urban values. Migrant workers collective identities are constructed through their self-produced media artifacts. The third case looks at how New Rural Reconstruction (NRR) movement leverages mainstream discourses and conducted a series of experiments aiming to change economic, social, and cultural relationships in rural China. The diversity of cases is to obtain more complex view on real-life contention and avoid oversimplifying the thick meaning of "hidden transcript" across different movements. The thesis concludes that the success of hidden resistance cannot be solely defined by mainstream media visibility. Looking beyond confrontations portrayed in media reporting, this thesis argues that participants' practices of alternative media forms assist them in mobilization and organization, and resistors' strategic interactions with different players in media system create opportunities for them to continuously implement incremental social change on the ground.<br>by Huan Sun.<br>S.M.

<p>Fear has found its latest instrument in the news media. The discourse of fear in news presentations produces gasping meanings, which we can compellingly indulge in. Fear not just being entertaining, but one of the ways in which we relate to reality, is used as a protection mechanism of our status quo. The purpose of this thesis is to examine the extent to which Fox News tends to use, and further reproduce, the fear discourse to form identities and meaning. The method utilized in this thesis is frame analysis, which is a form of discourse analysis. The primary results indicate that Fox News undeniably uses the fear discourse, for entertainment and the proliferation of the status quo - meaning system. In addition, Fox News applies fear blatantly in the news presentations, as acts of courage and virtuous loyalty to reporting.</p><p>Key words: Fear, Frame analysis, Meaning, News media, Infotainment.</p>

Testo completoAbstract (sommario):
Understanding the process of transformational change currently taking place in the media industry is an urgent challenge for people working in the industry as well as for media consumers and other stakeholders. There is a great need to deepen our general knowledge when it comes to what the future media landscape will look like. Which of the major consumption trends that exist today will continue and possibly lead to disruptive change? Which of today’s existing trends could give us a hint of tomorrow’s media landscape? Furthermore, we need to explore the environmental impact of the future media landscape. What parameters are important when it comes to environmental aspects of media consumption, as well as in the production and distribution of media content? These are examples of the questions explored in this thesis. I have used a number of methods, such as qualitative interviews, workshops, scenarios, case studies, process studies and life cycle assessment, in order to explore the research questions. The characteristics of the media consumption trends are presented in four scenarios. I have assumed that the strength of influence from the government in combination with the strength of commercial powers will strongly affect the future of media. The development of media is framed by the economy, the political system, and by culture. The future of media is closely connected with its relationship to the power structures in society. I have also defined eleven parameters, as central when discussing the environmental aspects of media consumption. These parameters are related to electronic devices, travel, transportation, energy use and waste. In the future, we may see the realisation of some of all four scenarios described in this thesis. The environmental aspects of these different future directions depend on each person’s life situation and a number of choices that each consumer makes concerning environmental issues, in combination with the overall societal structure. In relation to the global challenge of climate change/global warming, I conclude that traditional media, public service media in particular, together with social media channels play an important role in the process of increasing knowledge and awareness among consumers, politicians and other stakeholders in society. However, in current media development, media companies are rapidly becoming more commercialized and more focused on entertainment instead of on producing serious journalism concerned with social, political and cultural matters. To conclude, I believe that it is possible to create a sustainable media system, but it will require some conscious effort of people working in the media industry, of consumers, and ultimately at the level of regulatory authorities.<br><p>QC 20150416</p>

In this paper the authors examine three questions: 1) Is stealth marketing messages posing as status updates on Facebook a more effective way of advertising than traditional web banners? 2) What impact has learning about stealth marketing practices in social media on consumer attitude and post purchase behaviour? And finally 3) Will different generations respond differently to these questions? Our findings show that stealth marketing in social media is not more effective than traditional web banners. Furthermore, the result indicates that when consumers find out about stealth marketing practices it will have a negative impact on future purchase intensions and brand image. Most consumers will also have strong feelings of being deceived, which could instigate harmful post purchase behaviour such as negative word-of-mouth and possibly, based on some earlier cases, boycotts. The result of our research shows that the brand perceptions and future purchase intentions of Generation Y, persons between 18 and 30 years of age, are affected in a less negative way than the brand perceptions and future purchase intentions of older generations when finding out about stealth marketing practices in social media. However Generation Y:s reaction is still negative and they do consider traditional web banners to be more credible than status updates on Facebook. Thus contrary to traditional marketing literature and popular opinion in the advertising industry, our findings strongly indicate that stealth marketing in social media is not the right way to reach any generation, and certainly not Generation Y.

The contact angle defined by Young's equation depends on the ratio between solid and liquid surface energies. Young's contact angle is constant for a given system, and cannot explain the stability of fluid droplets in capillary tubes. Within this framework, large variations in contact angle and explained aassuming surface roughness, heterogeneity or contamination. This research explores the static and dynamic behavior of fluid droplets within capillary tubes and the variations in contact angle among interacting menisci. Various cases are considered including wetting and non-wetting gluids, droplets in inclined capillary tubes or subjected to a pressure difference, within one-dimensional and three-dimensional capillary systems, and under static or dynamic conditions (either harmonic fluid pressure or tube oscillation). The research approach is based on complementary analytical modeling (total energy formulation) and experimental techniques (microscopic observations). The evolution of meniscus curvatures and droplet displacements are studied in all cases. Analytical and experimental results show that droplets can be stable within capillary tubes even under the influence of an external force, the resulting contact angles are not constant, and bariations from Young's contact angle aare extensively justified as menisci interaction. Menisci introduce stiffness, therefore two immiscible Newtonian fluids behave as a Maxwellian fluid, and droplets can exhibit resonance or relaxation spectral features.

Testo completoAbstract (sommario):
FMR spectroscopy is widely used for the characterization of many types of magnetic materials for use in an extensive range of applications. It is a powerful tool for probing both the magnetic properties and physical aspects of a material. In recent years in particular, there has been some interest in its use to study commercial recording media. However, there are a number of limitations inherent in the conventional method of observing FMR that restricts its usefulness and popularity as a research technique. The high, single frequency operation of the spectrometer makes broadband, frequency dependent measurements and studies of the unsaturated state of materials impractical. It also severely limits the quantity of data available making the analysis and interpretation difficult and prone to error. Additional complexities are encountered since the swept field technique means that a sample is subjected to a constantly changing magnetic environment which may not be ideal, especially for broad linewidth materials. A need, therefore, has been identified for an FMR technique capable of producing both swept field and swept frequency spectra over a wide range of frequencies. The design and development of a novel broadband FMR spectrometer is described in this thesis. The new technique has several advantages over similar methods presented in the literature. It can be applied over a very wide frequency range, dependent on the types of materials, for a variety of different FMR studies. The spectrometer itself is straightforward and easy to use and the resulting spectra (which show excellent agreement with equivalent conventional data) may be interpreted using the same models already used in FMR research. Most importantly, the simplicity of this spectrometer design means that it can be readily implemented in any reasonably equipped magnetics or microwave laboratory without the need for specific expertise or equipment. A preliminary broadband FMR study of magnetic recording media demonstrates the potential of the new technique both for more detailed characterizations of magnetic materials and for greater understanding of the ferromagnetic resonant effect itself.

Scott, Nicola Louise. "Stability studies of porous media including surface reactions." Thesis, Durham University, 2013. http://etheses.dur.ac.uk/9421/.
Testo completoAbstract (sommario):
We investigate the onset of thermal convection in a number of porous models, with a focus on the influence of a boundary reaction. The models that we consider are: the Darcy porous model; the Darcy model with inclusion of the Soret effect and the Brinkman model, all with an exothermic surface reaction on the lower boundary. Numerical results are presented for each of these models and we show that the Darcy and Brinkman models with a surface reaction are structurally stable. Finally we derive stability results for a vertical porous channel that is in thermal non-equilibrium. In Chapter 2 we investigate how the parameters of an exothermic reaction on the lower boundary of a horizontal Darcy porous layer affect the linear instability boundary. We show that for low Lewis numbers stationary convection is dominant and for larger Lewis number oscillatory convection dominates. We use a non-linear analysis to and stability boundaries for this model in Chapter 3, showing how some of the reaction parameters affect this boundary. It is shown that the two boundaries do not coincide and there is a region in which sub-critical instabilities may occur. Structural stability on the reaction parameters is established for this model in Chapter 4. The impact of including the Soret effect on the stability of the Darcy model with a surface reaction on the lower boundary is considered in Chapter 5. When stationary convection dominates we find that increasing the Soret effect increases the critical Rayleigh number that defines the instability boundary. Chapter 6 discusses instabilities in a highly porous layer with an exothermic surface reaction on the lower boundary. The Brinkman model is used to take into account the impact of higher level derivatives of the fluid velocity. We show that this model is structurally stable on the parameters of the reaction in Chapter 7. Finally, in Chapter 8 we analytically derive two stability results for a vertical porous channel in thermal non-equilibrium. The first is that the model is stable for any initial data provided the Rayleigh number is below a given threshold. The second is that there is stability for any Rayleigh number given restrictions on the initial data.

The aim of this research study is to analyse the nature of undergraduate media studies in England, necessarily from the inside, and document the social practices that constitute the subject in the light of its historic and contemporary challenges and the influence of changing public higher education discourses over the period of the fieldwork, 2012-2013. Conceptually, media studies is regarded as socially constructed and enacted through discursive practices that reveal the nature of the power relationships that are the basis of the ways ‘things get done’. This approach is based on Foucault’s (1984, 2002a, 2002b, 2002c) conception of power and discourse and dovetails with a substantial part of the sociology of higher education. The fieldwork consisted of a series of semi-structured face-to-face interviews with a range of participants drawn from media studies lecturers, other university professionals, media studies graduates and a secondary school headteacher with experience of advising university applicants. This provided examples of discursive practices from both ‘inside’ and ‘outside’ media. The thematic analyses of the data show a complex set of interacting oppositional discourses that are skilfully managed by these professional practitioners to maintain a balance of Foucauldian power. This ensures that public policy changes are assimilated and ‘delivered’ whilst sometimes also mitigating their impact and maintaining a prevailing rationale for media studies. The study concludes by contrasting the findings with the emerging discourses of Critical University Studies (CUS). With a declared position (Williams, 2012a) in opposition to higher education public policy reforms, CUS is considered as a set of academic discursive practices that are distinct from the more nuanced balance of oppositional discourses evidenced through the participant responses here.

Testo completoAbstract (sommario):
Non-Newtonian flow in heterogeneous media is of enormous theoretical and industrial importance. This phenomenon is studied to reveal macroscopic effects that arise due to the interaction between the non-linear flow behaviour and the spatial variation of the medium through which it is forced to move. The heterogeneity is achieved by using porous granular media, which is naturally non-homogeneous. The non-Newtonian properties of the fluid may have many causes and is an intrinsic property of the fluid that is used: One way of achieving it is by studying dense slurries of neutral particles or naturally occurring magmatic flows. Another way is to study the case where the flow is dominated by its ionic content and where the double layer thickness (the effective size of the ionic entities) is of the order of magnitude of the pore size. All cases studied in this thesis pertain to slow flow (low Reynolds number), though the fluid may be compressible. The variations in the flow are calculated in first order and these turn out to be coupled to the spatial variations in the porous medium. In this way structure formation is predicted. The structures may be either aligned with or may be perpendicular to the mean flow direction. 'Experiments to decide on which regime is relevant have been conducted. The genesis of structure formation is studied as a temporal development by considering a compressible flow. The constitutive equation that is required to couple the compressibility to the flow parameters is investigated. Two possible mechanisms have been identified: compressibility coupled to the pressure field and compressibility associated with the fluctuations in the flow. Using linear analysis the structure formation patterns associated with these two mechanisms are established for the steady state. Flow of ionically laden fluids has also been studied. Experiments done at Loughborough University (Department of Chemical Engineering) on electrowashing of filter cakes has been used to prove a major macroscopic effect. This effect takes place when the ionic diameter (which is approximately twice the double layer thickness) is of the order of magnitude of the pore size. A phenomenological set of transport equations has been set up. These contain coefficients, such as transition probabilities and mean ionic flow rates, that can be obtained from experiments by doing a first order solution of the equations for short times. A more involved numerical solution is also supplied and confirms the initial analytical estimates.

Testo completoAbstract (sommario):
The Afghan war post 9/11 has become the source of multiple case studies. Recent studies suggest that variations in domestic support for deployment of troops in Afghanistan can be explained by means of the strategic narratives provided by the policymakers of the contributing state; a strong consistent narrative increases public support. Scholars recognize a Swedish catch-all narrative, which suggests weakens the narrative, thus raising the uncertainty among the public. This thesis investigates the projection of Swedish strategic narrative through elite Swedish newspapers. The content analysis reveals an inconsistency between the policymaker’s formation of the strategic narrative and the narrative projected by individual newspapers. The finding suggests that the lack of a strong strategic narrative due to the inconsistencies raised an uncertainty among the public during the period. The results recognize media to be a significant, but surprisingly unnoticed actor in the projection of policymakers’ strategic narratives.

Jacksonrättegången är en lokal händelse som förflyttats till de svenska nyhetstidningarna. Resultatet av analysen visar även att förmedlingen av Jacksonrättegången skiljer sig åt i de båda nyhetstidningarna då Aftonbladet lägger större fokus vid händelsen och den får en följetongskaraktär. Aftonbladet bygger upp förmedlingen av Jacksonrättegången som ett narrativ med en början och en mitt. Eftersom rättegången pågår går det inte att uttala sig om slutet. De förbereder därmed läsarna på att rättegången ska äga rum genom att publicera artiklar innan rättegången vilket Dagens Nyheter inte gör. Dagens Nyheters förmedling sker oftast i form av korta rapporter. Dramaturgi används i båda nyhetstidningarna även om</p><p>Aftonbladet lägger större fokus på det. Aftonbladet använder sig i större utsträckning av vinkling i form av personifiering. Förmedlingen av Jacksonrättegången rör sig främst inom den privata sfären eftersom det Jackson anklagas för begåtts i intimsfären. Dagens Nyheter uttrycker sig mer försiktigt medan Aftonbladet gräver sig djupt ner i intimsfären. Jacksonrättegången uppfyller kraven för nyhetsvärdering bl.a. genom att vara en färsk nyhet som handlar om ett eventuellt brott begått av en känd person, men Aftonbladet cirkulerar nyheten i större omfattning än Dagens Nyheter.</p>

The work was, however, based on a study of 18 stable, mature and highly developed democracies either in Europe or in North America. As an emerging democracy that has recently undergone dramatic change in both its political system and its media, South Africa's inclusion poses particular challenges to Hallin and Mancini's Three Models paradigm. This thesis focuses on the South African print media and tests both the paradigm's theoretical underpinnings as well as its four principle dimensions of analysis: political parallelism, state intervention, development of a mass market and journalistic professionalisation. A range of insights and a number of modifications are proposed. This thesis is based on interviews with South Africa's most senior media executives and editors, a comprehensive study of the relevant literature and 15 years of personal experience as a political analyst, columnist and parliamentary correspondent covering South Africa's transition from apartheid to democracy. The thesis sheds new light on the functioning and applicability of the Three Models comparative paradigm as well as on the development and future trajectory of South African print media journalism.

Testo completoAbstract (sommario):
Social media is playing a significant role in our everyday life. New tools are emerging everyday and offer the users exciting opportunities. Not just ordinary people use social media.It became very popular among companies, politicians and government. But using social media does not guarantee one instant success and benefits. The right appliance of social media technologies can do wonders. Barack Obama brilliantly illustrated that during his presidential campaign in 2008.In 2012 social media technology was yet again at the heart of the Obama’s campaign. His challenger, Mitt Romney, also engaged digital technology into his campaigning process. However, the attention and participation Romney generated online was more humble compared to Obama, who yet again mastered the technology. This thesis studies the differences in social media use between the two campaigns and aims to find out how different use of social media can influence behavior and participation of the online audience. The study addresses the theory of communicative action, new social movements theory and agenda setting.

Testo completoAbstract (sommario):
Alternative media, as another choice for the public besides mainstream media, has been increasingly growing in Taiwan during the era of Web 2.0. In an attempt to report social issues properly, alternative media is trying to break the hegemonic range of mainstream media while being oriented by the public. Civil Media@Taiwan has been established since the year of 2007. During its ten-year history, Civil Media@Taiwan has identified itself as an alternative medium. Although the rise of alternative media has been studied by researchers from different fields, there have been very few studies on alternative media in Taiwan. The aims of this study are first to reveal the principles and practices of alternative media, then to investigate whether Civil Media@Taiwan is alternative media or radical media. The theoretical approaches used in the research include the theories on alternative media, and theories on radical media. Content analysis on the official website of Civil Media@Taiwan and semi-structured interviews of fourteen interviewees are utilized as the methodology. The study has two research questions, which examine whether Civil Media@Taiwan is alternative or radical, and how it serves the public. The journalistic profession and the organization of Civil Media@Taiwan are investigated in order to answer the research questions. The results of the study conclude that Civil Media@Taiwan is partly alternative and partly radical, but combining the characteristics of both kinds of media. Moreover, Civil Media@Taiwan serves the public by challenging the rules of journalism and broadening the hegemonic range from mainstream media.

Testo completoAbstract (sommario):
<p> This study examines how conflict between public assumptions and media framing of a political candidate’s gender performance impacts public trust in the candidate, building upon prior research concluding that the Republican and the Democratic Parties are linked cognitively with ideas about gender, with people often associating the Republican Party with masculine characteristics and the Democratic Party with feminine characteristics. This study operates under the theory that conflict between media representation and participant assumptions will lead to lower levels of trust in a candidate whose gender is framed as conflicting with the underlying gendered assumptions of their party. In an experiment, subjects read one of six news articles describing a hypothetical presidential candidate and answered a questionnaire to measure their trust in the candidate. The results indicate that participants have a higher level of trust in the feminine-framed candidate and a lower level of trust in the masculine-framed candidate – in comparison to the baseline of a gender-neutral framed candidate – in both the Democrat and the Republican condition. Further analysis of the results suggest that while participants assume all candidates possess certain masculine traits often associated with leadership, the presence of feminine traits may increase a candidate’s perceived likeability, which in turn leads to the perception that the candidate has a higher degree of integrity, is more responsive to public concerns, and is ultimately more trustworthy. Additionally, the presence of masculine traits may threaten the candidate’s perceived trustworthiness without the presence of feminine traits to increase the candidate’s likeability. This study expands the current conversation about media and gender to look beyond a candidate’s sex and consider the media’s role in constructing and reinforcing a candidate’s gender performance. It also provides a foundation for future research about the media’s power to shape public perception of candidates and, by extension, the electoral process.</p>

The third chapter examines the FlyLady - a transmedia property with a strong internet base, described by its founder as a "behavior modification system" that coaches its subscribers in getting their houses in order. This study was driven, among other things, by the following questions: as the 'commodity frontier' gets increasingly intermingled with our daily lives, with the help of increasingly pervasive media, how do certain communities respond, and with what methods of meaning-making? What draws audiences to engage with media properties so intermingled with commerce in the first place? And, what constitutes these properties' entertainment value as well as the other values audiences find in them? The answers vary with each case study, yet, there are many commonalities pertaining to meanings associated with consumer goods in late capitalism. The media properties described here capitalize on the movement of meaning from culture through consumer goods to individuals. At the same time these three chapters exemplify many cases of redirecting, filtering, and damming up the flow of meaning on the part of viewers and subscribers.<br>by Orit Kuritsky.<br>S.M.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Comparative Media Studies, 2006.<br>Includes bibliographical references (leaves 199-206).<br>Introduction: Rehoboth, the name of my hometown in southern Massachusetts, comes from the Hebrew work for "crossroads." Indeed there's not much in this rural town besides Route 44 and Route 118, with smatterings of horse farms and single-family homes. These two blue highways intersect at the town's only stoplight. A sign stands at this intersection at the center of town, in front of the Cumberland Farms convenience store, across the street from the new Dunkin Donuts. It reads: Rehoboth, MA: Birthplace of Public Education in North America. I'm a product of these schools, but in this thesis I explore the road not often traveled in education: unschooling, a type of homeschooling with unstructured, child-directed learning. Through an examination of the attitudes, beliefs and practices related to media and technology in the unschooling subculture, I come to a definition of participatory media.<br>by Vanessa Bertozzi.<br>S.M.
