No / Although ads with subtle racist imagery can reinforce negative stereotypes, advertisers can eliminate this problem. After a brief overview of predominantly U.S.-based research on the racial mix of models/actors in ads, a theoretical framework for unmasking subtle racial bias is provided and dimensional qualitative research (DQR) is introduced as a method for identifying and rectifying such ad imagery. Results of a DQR-based study of 622 U.K. television ads with at least one Black actor indicate (1) subtle racially biased imagery now supersedes overt forms, and (2) the most popular ad appeals often mask negative stereotypes. Implications for public policy and advertisers, as well as recommendations for future research, are discussed.

The problem of this study is to determine the relation of a pupil's capacity in spatial and visual imagery to his drafting achievement, and to his mechanical aptitude.

<p>Blakeslee och Goff (2007) föreslår att dressyrryttares visualiseringsfärdigheter bör skilja sig från andra sporter som inte involverar ett djur. Enligt Murphy, Nordin och Cumming, (2008) finns det ett behov av ett instrument som tar hänsyn till visualiseringstyp, funktion och dess utgång. The survey of imagery experiences in sport (SIES; Weibull & Wallsbeck, 2009; Wallsbeck & Weibull, 2009) är ett relativt nytt instrument som mäter dessa variabler. Syftena i denna studie var därför att: (1) studera elitdressyrryttares visualiseringsupplevelser, (2) studera elitdressyrryttares förståelse och (3) upplevelse av instrumentet SIES. En kombination av kvalitativ och kvantitativ metod användes i studien. Dressyrryttarnas visualiseringsupplevelser skiljde sig till viss del från tidigare forskning.

<p>Motion är viktigt för vår hälsa, men många som börjar motionera slutar inom en snar framtid (Fallon, Hausenblas, & Nigg, 2005). Det är därför viktigt att utveckla strategier som motiverar människor till träning. Visualisering är en teknik som visats ha en motivationshöjande effekt hos motionärer. Kim och Giacobbi (2009) menar dock att det finns ett behov av att skilja på innehåll, syfte och effekter inom motionsvisualiseringen och att ett nytt mätinstrument därför behövs. Syftena med studien var därför att: (1) utveckla och testa mätinstrumentet the Individual Profile of Imagery Experiences in Exercise (IPIEE; Weibull & Johnsson 2010), samt att (2) studera motionärers frivilliga och spontana visualiseringsupplevelser. De teoretiska referensramarna som användes var Den Analytiska Referensramen för Visualiseringsupplevelser (Weibull, 2009) samt An Applied Model of Imagery Use in Exercise (Munroe-Chandler & Gammage, 2005). Resultat visar att IPIEE fungerade väl, att motionärerna använde flest frivilliga visualiseringsmönster för syftet motivation och att flest spontana visualiseringsmönster hade effekt på motivationen. De vanligaste innehållen i visualiseringsmönstren var Träningssituationer följt av Icke träningsrelaterade händelser/situationer.

Bien que le phénomène de co-Création prenne de l'ampleur dans les pratiques actuelles des entreprises, ces dernières se déclarent souvent déçues par la faible créativité effective des utilisateurs « ordinaires » à générer des idées de nouveaux produits. Ce travail doctoral cherche à répondre au questionnement général suivant : peut-On améliorer l'efficacité des démarches de co-Création avec des utilisateurs ? Si l'identification des utilisateurs créatifs est un enjeu crucial pour les entreprises, il est également essentiel pour ces dernières de faire en sorte de stimuler les capacités créatives des utilisateurs enrôlés dans les processus d'innovation. Cette thèse s'intéresse donc au phénomène d'imagerie mentale qui a souvent été souligné en psychologie pour son implication dans les processus créatifs. Trois études quantitatives explorent la relation entre la capacité individuelle d'imagerie mentale et la capacité créative de sujets. Les résultats obtenus identifient la capacité d'imagerie mentale comme une variable révélatrice de la capacité créative des individus et constituant ainsi un élément possible d'identification des individus créatifs. Une quatrième étude montre qu'il est possible d'agir, par le biais d'instructions d'imaginer mentalement, sur les processus d'imagerie suspectés d'être en œuvre dans les processus créatifs, de manière à améliorer la créativité résultante. Ces résultats mettent en évidence l'imagerie mentale comme un mécanisme sous-Jacent explicatif des processus créatifs. Enfin, une cinquième expérimentation, plus conséquente en matière de variables examinées, étudie l'effet de deux types de stimulations de l'activité d'imagerie, à savoir : la présence d'une stimulation d'imagerie liée à soi (versus non liée à soi) et la présence (versus l'absence) d'un entraînement préalable à l'imagerie mentale. L'étude confirme le rôle médiateur de l'imagerie mentale et met en évidence les effets favorables de ces stimulations sur la quantité, l'originalité, l'utilité perçue et l'attrait des idées produites. Le rôle modérateur de variables individuelles – le caractère lead user et l'implication envers la catégorie de produit – a également été examiné. / Although co-Creation is a phenomenon increasingly present in various business practices, companies are often disappointed by the low effective creativity of "ordinary" users to generate ideas for new products. This doctoral research aims to answer the following general question: Can we improve the effectiveness of co-Creation processes with users? If the identification of creative users is a critical issue for businesses, then it is also essential to ensure stimulation of the creative abilities of the users enrolled in the innovation process. This thesis is interested in mental imagery, a phenomenon that has often been cited in psychology for its implication in the creative process. In this work three quantitative studies explore the relationship between the individual's imagery ability and their creative ability. The obtained results identify the mental imagery ability as a variable indicating the creative ability of individuals and thus constituting a potential element for identifying creative individuals. A fourth study shows that it is possible to impact, via instructions to form mental images, the mental imagery process that is implemented in the creative process, thus improving the resulting creativity. These results highlight mental imagery as an underlying mechanism of the creative process. Finally, a fifth experiment, more consistent in terms of the variables examined, studies the effect of two types of stimulation of imagery activity: self-Related vs. non self-Related imaging stimulation, and the presence vs. absence of mental imagery training. The study confirms the mediator role of mental imagery and highlights the favorable effects of these stimulations on the quantity, originality, perceived usefulness and the customer appeal of the generated ideas. The moderator role of individual variables - leadership and involvement with the product category - was also examined.

Doctor of Philosophy / Department of Geography / Douglas G. Goodin / Prescribed burning in tallgrass prairie affects a wide range of human and natural systems. Consequently, managing this biome based on sound science, and with the concerns of all stakeholders taken into account, requires a method for mapping burned areas. In order to devise such a method, many different spectral ranges and spectral indices were tested for their ability to differentiate burned from unburned areas at both the field and satellite scales. Those bands and/or indices that performed well, as well as two different classification techniques and two different satellite-based sensors, were tested in order to come up with the best combination of band/index, classification technique, and sensor for mapping burned areas in tallgrass prairie. The ideal method used both the red and near-infrared spectral regions, used imagery at a spatial resolution of at least 250 m, used satellite imagery with daily temporal resolution, and used pixel-based classification techniques rather than object-based techniques. Using this method, burned area maps were generated for the Flint Hills for every year from 2000-2010, creating a fire history of the region during that time period. These maps were compared to active fire and burned area products, and these products were found to underestimate burned areas in tallgrass prairie.

According to Plato, we live in a substitute world. The things we see around us are shadows of reality, imperfect imitations of perfect originals. Beyond the world of the senses, there is another, changeless world, more real and more beautiful than our own. But how can we get at this world, or attain knowledge of it, when our senses are unreliable and the perfect philosophical method remains out of reach? In the Divided Line passage of the Republic, Plato is clear that mathematics has a role to play, but the debate about the exact nature of that role remains unresolved. My reading of the Divided Line might provide the answer. I propose that the ‘mathematical’ passages of the Meno and Phaedo contain evidence that we can use to construct the method by which Plato means us to ascend to knowledge of the Forms. In this dissertation, I shall set out my reading of Plato’s Divided Line, and show how Plato’s use of mathematics in the Meno and Phaedo supports this view. The mathematical method, adapted to philosophy, is a central part of the Line’s ‘way up’ to the definitions of Forms that pure philosophy requires. I shall argue that this method is not, as some scholars think, the geometric method of analysis and synthesis, but apagōgē, or reduction. On this reading, mathematics is pivotal on our journey into the world of the Forms.
