<p>Twitch.tv is a new phenomenon in the world of gaming and online entertainment. Advertising professionals could use Twitch.tv as a new outlet to advertise brands to their audiences. To further understand brand recall of advertisements on Twitch.tv, this thesis examined different variables such as game experience, ad placement, and ad familiarity. The Limited Capacity Model of Motivated Mediated Message Processing (LC4MP) relates to effects on viewer recall of brands in advertisements seen on Twitch.tv, as it is ultimately a new form a television and this model can help understand how its messages are processed (Lang, 2000). A 2x2 factorial design was used to determine interactions between brand familiarity and advertisement placement as well as their effects on brand recall. Game experience was used as a covariate to determine if this variable further made a difference in brand recall of advertisements on Twitch.tv.

<p> The study investigated the existence of some generic and non-generic media frames in the campaign speeches of Donald Trump and Hillary Clinton using content analysis. The comparison of the two political actors in their usage of frames in their campaign speeches revealed that Donald Trump exploited economic consequence, conflict, morality, attribution of responsibility, and negative campaign frames more than Hillary Clinton. Hillary Clinton did not socially exclude any minority group within and outside the United States of America. Both Donald Trump and Hillary Clinton are equal in their utilization of the human interest frame, positive campaign, and mixed campaign. If campaign speeches were moderators of candidates&rsquo; electoral victory, negative campaign is, therefore, a facilitating factor in affecting voters' behavior considering the success of Trump in the polls. Nevertheless, the commonness of mixed campaign to both the political candidates indicates that a discrete use of any of the generic frames by political actors and communicators may not be a certainty for changing voters&rsquo; behavior. Instead, scholars and professionals should treat frames as discretional communication tools applicable and dependent on the context of a social environment in which many factors exist and determine the choice of frames in communicating between the speech actors and the audiences.</p><p>

Thesis (M.Arch.)--Massachusetts Institute of Technology, Dept. of Architecture, 2003. / Includes bibliographical references (p. 71). / The climate of the reception of immigrants to the United States has soured, and circumstances are becoming increasingly difficult for persons seeking to gain residency. Reasons often given for the reversal in this practice are that immigrants are poor, uneducated, take jobs away from Americans, and use valuable resources otherwise available to the native-born. This at-best cautionary condition is unfortunate, not only because it decreases diversity in a society already afraid of "the other", but because the US is the very model founded on foreigners trying to make lives for themselves. In evidence now is a disdain and distrust of foreigners that could eventually affect all people in the US, resulting in an atmosphere of suspicion and negativity toward anyone who is perceived as different. This design thesis posits that immigrants are important additions to local neighborhoods and economies. If they are supported physically and psychologically during their initial period of arrival, they can more readily become integral members of American society. The design of housing, a learning center, and incorporation of the arts becomes a new means by which immigrants can retain ties to their cultural heritage, while concurrently increasing self-sufficiency, dispelling ignorance, and fostering greater acceptance and knowledge in the community at large. / Britta Erika Butler. / M.Arch.

Aujourd'hui, la durabilité des structures en matériau cimentaire est un des facteurs importants dans les domaines du génie civil et du génie industriel. Elle est influencée non seulement par les chargements mécaniques mais aussi par l'environnement (pollution, pluie...). Ces influences deviennent plus importantes quand on doit garantir une durée de service du matériau pendant une grande période. Le mécanisme de dégradation chimique du matériau cimentaire consiste à une décalcification progressive au cours du temps en contact avec un environnement agressif (par exemple l’attaque par les chlorures, par les sulfates, les cycles gel-dégel, l’alcali-réaction). Cette dégradation provoque la variation de la porosité du béton qui modifie les propriétés physico-chimiques et mécaniques. D'une part cette variation de porosité accélère le processus de transport de matières et entraîne une accélération de la dissolution des hydrates (notamment la portlandite). D'autre part, ceci induit une modification des propriétés mécaniques, notamment le retrait. En plus, les sollicitations mécaniques créent des microfissures qui peuvent être des facteurs accélérant le processus de dégradation chimique. Ce travail de thèse est réalisé pour étudier le phénomène physico-chimique de la carbonatation sur les matériaux cimentaires comme les mortiers et les pâtes de ciment à la base CEM I et CEM III. Le but principal de cette étude est de caractériser expérimentalement et numériquement les effets du dioxyde de carbone (CO2) sur la durabilité et les propriétés mécaniques d’un matériau cimentaire. Dans la partie expérimentale, nous prenons en compte quelques paramètres importants tels que : le retrait, la variation de la porosité et de la masse en fonction de différentes teneurs en dioxyde de carbone (CO2) : 5%, 10%, 13%, 15%, 17%, 20%. Le modèle numérique basé sur l’approche physico-chimique de Bary et Sellier (2004) nous permet de valider les paramètres qui influencent le phénomène de carbonatation en matériau cimentaire comme le taux de saturation en eau, la pression partielle de dioxyde de carbone (CO2), la concentration en ions calcium et la porosité. Ceci confirme que les transferts de dioxyde de carbone (CO2) en phase gazeuse couplent avec les transferts de l’eau liquide et des ions du calcium Ca2+ en solution aqueuse au cours de la carbonatation. / Today, the durability of structures in cementitious materials is an important factor in the areas of civil engineering and industrial engineering. It is influenced not only by mechanical loads but also by the environment (pollution, rain ...). These influences become more important when one has to guarantee a service life of materials for a great period. The mechanism of chemical degradation of the cementitious material is a progressive decalcification over time in contact with aggressive environments (e.g. attack by chlorides, by sulfates, freeze-thaw cycles, alkali reaction). This degradation causes the variation in the porosity of the concrete that modifies the physico-chemical and mechanical properties. On the one hand, the change in porosity accelerates the transport of substances and causes an acceleration of the dissolution of hydrates (notably portlandite). Moreover, this induces a change in mechanical properties, especially shrinkage of carbonation. In addition, the mechanical stress creating microcracks that may be factors accelerating the process of chemical degradation. This work is carried out to study the physicochemical phenomenon of carbonation on cement-based materials such as mortars and cement pastes based on CEM I and CEM III. The main purpose of this study is to characterize experimentally and numerically the effects of carbon dioxide (CO2) on the mechanical properties and durability of cementitious material. In the experimental part, we take into account some important parameters such as shrinkage, variation of porosity and variation of mass in terms of different concentrations of carbon dioxide (CO2): 5%, 10%, 13%, 15%, 17%, 20%. The numerical model based on the physico-chemical approach by Bary and Sellier (2004) allows us to validate the parameters that influence the carbonation in cementitious material as rate of water saturation, partial pressure of carbon dioxide (CO2), calcium ion concentration and porosity. This confirms that the transfer of carbon dioxide (CO2) in gas phase couple with transfers of liquid water and calcium ions Ca2 + in aqueous solution during carbonation.
