Bolstering Opportunity and Prejudicial Expectation Effects on Recall When Appraising Performance Potential

Atkins, Stephen G. Jr. 28 September 1998 (has links)
This research program investigated the reasonable possibility that differential information processing strategies can be manifestations of racist prejudgments. Our research design applies a technique often used in social cognition studies. This technique captures evidence of a rather habit-driven (though not instantaneous) decision made by subjects rapidly presented with information about (typically fictional) characters. These target characters are associated (in the context of the experiment) with some form of generalized expectancy (i.e., they are typically presented as a likable or unlikable person). This is accomplished either by creating the expectancy artificially, or by using targets that are members of a conspicuously or notably-stereotyped group. The rather non-conscious decision involved is one of either bolstering one's pre-conceived notions or engaging in inconsistency resolution (e.g., either marshaling evidence to bolster your prejudicial expectation or pondering more earnestly those pieces of information which are inconsistent with your expectancy or well-known prejudicial stereotypes). Typically, the likelihood of pursuing one strategy or the other is manipulated in experimental settings by first providing an artificial expectation, then altering the structure of the person-memory task or adjusting the rate of information flow to the subjects. We hoped to reveal how a non-artificial pre-existing race-based prejudicial expectancy (of a largely non-evaluative as in non-likable/dislikable nature) might effect the pursuit of one strategy or the other. By and large, tests of our five hypotheses provide only mixed support for use of a person-memory associative network model in this context. The first and second hypotheses have some visual support (i.e., recall proportions across sentence types start out roughly equal for low prejudicial expectation - PE -- subjects then branch out; high PE subjects seem to treat sentence types differently from the start); however, these differences are not amenable to clearly interpretable statistical tests. Analysis of the third and fourth hypotheses was confounded because the candidate contaminating covariate failed to have consistent effects. This, coupled with the floor effect of the PE scale, the unexplained (and substantial) variability in recall behavior, and some other control issues (detailed below), made the use of the continuous DVs less than fruitful. The floor effect of the PE scale was especially problematic - with many subjects compressed at this floor, relations would be difficult to see even if present. In an attempt to detect weak effects of prejudice, we aggregated subjects by PE (as in high and low prejudice). Aggregation probably made the floor effect-driven range restriction less problematic (the subjects lumped together on PE's floor are probably less-afflicted with well-practiced prejudicial expectations than the high half of PE scorers). This exercise generated weak support for the third hypothesis: the time interval data feebly indicates that high PE subjects manifest a negative impression-centered person-memory schema in their storage of sentences about a Black target - and, unlike the low PE subjects, they apparently do this starting with the earliest blocks of sentences. The median split approach failed to generate support for the fourth hypothesis - where we expected to see bolstering replace inconsistency resolution (in the slow condition) since subjects were afforded the time. There was weak evidence, however, that more inconsistency resolution was occurring in the fast condition (as the proposed model had predicted). This evidence was in the form of greater recall time interval differences seen when comparing high PE subjects and their schema-speeded versus non-speeded intervals. The bottom line for the first four hypotheses is still this: we failed to create a condition where prejudice would paradoxically favor recall of laudable or admirable inconsistencies associated with a fictitious Black target. The fifth hypothesis was just intended to verify that racial prejudice does not predict recall behavior when the target is White and so are the subjects. So using a White target, we performed the same sort of tests seen above. Fortunately, relations with PE ranged from weak to very weak - and, of course, were non-significant. In sum, these outcomes suggest that Hastie-Srull associative network (H-SAN) processing effects may not reliably or consistently manifest themselves in the prejudiced rater/performance appraisal arena -- at least not in designs similar to those used previously to illustrate H-SAN effects. There were some clear exceptions, however, in our data. Taken together, our results suggest that H-SAN mechanisms may apply when appraising performance potential, but have a difficult time manifesting themselves in substantial ways. / Ph. D.

Réparation de pièces et développement de matériaux à gradients fonctionnels à l'aide de la déposition sous énergie dirigée

Simoneau, Louis 18 October 2019 (has links)
La fabrication additive regroupe une famille de procédés de mise en forme des métaux permettant la fabrication de pièces à géométrie complexe qui n’étaient pas réalisables auparavant. Selon l'industrie, cette nouvelle technologie est intéressante au niveau économique et au niveau des nouvelles possibilités de conception de pièces que celle-ci rend maintenant possible. Parmi les nombreux procédés de fabrication, la Déposition sous Énergie Dirigée (DED) se distingue des autres technologies de fabrication additive par sa méthode de déposition de matière particulière. Utilisant une puissante source d’énergie sous la forme d’un laser, d’un faisceau d’électrons ou d’un arc plasma, celle-ci permet de créer des pièces en 3 dimensions à l’aide de poudre ou de fil d’apport. La DED est notamment reconnue pour sa capacité à réparer des pièces de manière efficace et sa facilité à créer des pièces présentant des gradients de composition chimique. Ces deux applications particulières ont fait l’objet de trois projets de recherche distincts qui composent ce mémoire de maîtrise. Le premier s’intéresse aux propriétés mécaniques de composites à matrice métalliques d’alliage detitaneTi-6Al-4V renforcés à l’aide de carbures de tungstène conçus à l’aide d’un appareil de type DED. Le second explore les propriétés mécaniques et la microstructure de pièces d’acier inoxydable 316L-Si entièrement construites et réparées avec un appareil DED. Finalement, le dernier ouvrage s’intéresse aux propriétés mécaniques et à la microstructure de pièces d’alliage d’aluminium AlSi7Mg entièrement construites et réparées grâce à la DED. / Additive Manufacturing (AM) is a novel manufacturing process that allows the creation of complex shaped metallic parts from scratch in a layer-by-layer fashion conversely to conventional subtractive processes. This new technology is interesting for many manufacturing industries since it can enable significant cost savings and allows the creation of completely new and more efficient designs that were not achievable before. Directed Energy Deposition (DED) is a sub-category of AM processes that set itself apart from the others with its clever deposition process design.Using a high-density energy source such as an electron beam, a laser or a plasma arc, this process melts feedstock in powder or wire form onto a base plate the create a dense depositand a final part in an iterative way. Thanks to its deposition process, DED apparatuses can create Functionally Graded Materials (FGM) parts exhibiting varying mechanical or physical properties within their volume and repair defective or broken parts. These two main applications were the subject of three different studies that are presented in this master’s thesis. In the first one, complex shaped Ti-6Al-4V Metal Matric Composites (MMC) reinforced with different fraction of tungsten carbides (WC) created with a DED apparatus were studied in terms of mechanical behavior and wear properties.The next paper looked at tensile properties and microstructure of completely built and repaired 316L-Si stainless steel parts with DED. Finally, the last one studied the microstructure and the mechanical properties of entirely built and repaired AlSi7Mgparts using DED.

Culture on a Plate: The Social Construction of Authenticity in Food Culture

Byrd, Kaitland Marie 21 April 2017 (has links)
This study uses three case studies to show how authenticity is fabricated in food culture. Conceptualizing food as a cultural product makes possible the analysis of social processes through food. In doing so, food becomes a mirror reflecting the happenings within the broader social world. This study examines three empirical cases to sociologically understand food culture: southern barbeque, Top Chef, and ramps and quinoa. Southern barbeque allows the examination of the role of fabricated authenticity within food culture. Top Chef is evidence of how chefs actively produce distinction to legitimate their position and status within the field. Ramps and quinoa are examples of two ingredients that have been exploited from their original context to become elite and mainstream ingredients without concern for the consequences to the people who relied on them in the quest for the exotic. Together these cases provide examples of how research on the fabrication of authenticity and impression management can be expanded to include food. / Ph. D.

Storytelling in organisations: supporting or subverting corporate strategy?

Spear, S., Roper, Stuart 2016 May 1929 (has links)
Yes / Purpose: Storytelling is claimed to be an effective way of communicating corporate strategy within organisations. However, previous studies have tended to focus holistically on storytelling in organisations rather than investigating how different groups may use and be influenced by stories. This paper addresses these gaps in the literature by investigating how storytelling in internal communication can either support or subvert corporate strategy. Design/methodology/approach: A qualitative study was conducted into storytelling in two large companies in the UK energy industry. Data was collected through 70 semi-structured interviews, documentary research, and observation research. Impression management theory was used to analyse how stories supported or subverted corporate strategy. Findings: Storytelling by employees in the corporate and customer service areas of the organisations showed the greatest support for corporate strategy. There was more subversive storytelling in the operational areas, particularly by lower level employees. Stories subverted corporate strategy by recounting incidents and encouraging behaviour that contradicted the organisation’s vision/goals and values. Originality/value: The study shows the important contribution of employees to the collective sensemaking process in organisations, by narrating supportive or subversive stories. Engaging employees in storytelling can enhance support for corporate strategy, however managers should also see subversive stories as an opportunity to identify and address problems in the organisation.

Formulation et impression d'une nouvelle génération de matériaux inspirée du PEDOT pour applications en photonique imprimée

Lapointe, Rosalie 06 June 2022 (has links)
Les capteurs électroniques sont utilisés dans une grande variété de domaines afin de répondre à différents besoins dans notre société. La médecine, la robotique et les téléphones intelligents en sont seulement quelques exemples qui marquent notre quotidien. Dans le cadre du Réseau canadien du CRSNG sur l'électronique imprimée verte (GreEN) le développement de capteurs (temps, température, humidité) imprimés à base de matériaux verts pour application dans les emballages intelligents figurent parmi les principaux objectifs de ce réseau pancanadien qui regroupe des chercheurs académiques de renom et des industriels du domaine de l'impression, de l'emballage et de l'alimentation. Le développement d'une étiquette « intelligente » permettrait la trace efficace, en temps réel, de produits alimentaires sensibles en assurant l'intégrité de la chaîne de froid afin de préserver la salubrité et les qualités gustatives des aliments. Plusieurs projets sont actuellement consacrés au développement de cet emballage fonctionnel dont le miens. En effet, mon projet de maîtrise vise principalement le développement d'un capteur de température imprimé en collaboration avec l'Institut National d'Optique (INO). Le principal objectif est de remplacer la thermistance à base de poly(3,4-ethylenedioxythiophene) polystyrène sulfonate (PEDOT:PSS) actuellement utilisé dans les capteurs de température développés à l'INO par un matériau dont les propriétés seraient indépendantes de l'humidité. Pour ce faire, des nouveaux matériaux, inspirés du PEDOT, ont été synthétisés et étudiés comme thermistance. Ces matériaux sont, contrairement au PEDOT:PSS qui est une suspension, 100% soluble dans l'eau ce qui facilite grandement l'impression. Dans le cadre de ce mémoire, la formulation, l'impression et la fabrication d'un capteur de température utilisant cette nouvelle génération de PEDOT seront présentés. / Electronic sensors are used in a wide variety of fields to meet different needs in our society. Medicine, robotics and telephones are just a few examples that mark our daily lives. As part of the "NSERC-Green Electronics Network", the development of sensors (time, temperature, humidity) printed on the basis of green materials for application in smart packaging are among the main objectives of this pan-Canadian network which brings together renowned academic researchers and manufacturers in the field of printing packaging and food. The development of the "smart" label would allow the efficient, real-time trace of sensitive food products while ensuring the integrity of the cold chain in order to preserve the safety and taste qualities of food. Therefore, several projects are currently devoted to the development of this functional packaging, including mine. Indeed, my master's project mainly aims at the development of a printed temperature sensor in collaboration with the National Optics Institute (INO). The main objective is to replace the thermistor based on poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) currently used in temperature sensors developed at INO with a material whose properties are independent of humidity. To do this, new materials, inspired by PEDOT, have been synthesized and studied as thermistors. These materials are, unlike PEDOT:PSS which is a suspension, 100% soluble in water which greatly facilitates printing. As part of this thesis, the formulation, printing and fabrication of a temperature sensor using this new generation of PEDOT will be presented.

Årsrapporters förändring över tid : Ett svenskt perspektiv

Bradley, Henrik, Andersson-Jit, David January 2016 (has links)
Årsrapporter producerade av bolag anses vara det traditionella sättet att kommunicera mellan publika aktiebolag och dess intressenter. Enligt tidigare forskning i andra länder har dock årsrapporters storlek och struktur förändrats. Uppsatsen syftar till att undersöka hur årsrapporters storlek och struktur har förändrats över en 11-årsperiod (2004-2014) i svenska noterade bolag, samt hitta motiven till varför årsrapporterna har förändrats. Väsentliga teorier valdes för att få en bättre förståelse avseende området, men även som möjliga motiv för förändrade årsrapporter. En innehållsanalys på de största noterade svenska bolagen mätt i omsättning år 2015 gjordes för att skapa en kartläggning av deras årsrapporter. Vi utgick från flera parametrar för att få en bild av förändringen, t.ex. sidantal, bilder och ord. Delar som vanligtvis ingår i årsrapporter kartlagdes även för att få en inblick i hur delarna har förändrats över tidsperioden. Studien visar på att årsrapporter i svenska noterade bolag generellt har ökat i storlek och att strukturen har förändrats från 2004 till 2014. Hållbarhetsredovisningen är den del i årsrapporter som procentuellt har ökat mest av alla delar. Vidare finner vi motiv och orsaker som kan vara påverkande faktorer för varför förändringen har sett ut som den gör. Införandet av IFRS 2005, Finanskrisen 2007-2008 samt teorierna information overload, impression management och legitimitetsteorin används för att nå resultatet. / Annual reports produced by companies are considered to be the traditional medium between limited companies and its stakeholders. However, according to previous research made in other countries, annual report size and structure has changed during the last decades. This essay aims to examine how annual reports size and structure has changed over an eleven year period (2004-2014) in Swedish listed companies, and to find the causes/reasons to why the annual reports has changed. Essential theories were mainly chosen to better understand the area, but also as possible motives for changed annual reports. A content analysis on the 25 biggest listed Swedish companies measured in revenue year 2015 was made to map how the change have looked for the companies. We started from several parameters to get a picture of the change, for example from number of pages, pictures and words. Parts that is usually included (e.g. management report, sustainable report, CEO/Chairman’s letter) in annual reports was mapped so that we could get an insight in how the parts had changed over the time period. The study shows that annual reports of Swedish listed companies generally have increased in size and that the structure has changed from 2004 to 2014. The sustainable reporting is the part of the annual reports that increased the most in percent of all the parts. Furthermore, we find motives and causes that can be seen as affecting factors to why the changes looks the way it does. The introduction of IFRS 2005, the financial crisis 2007-2008 and the theories information overload, impression management and legitimacy theory are used to reach the result of the study.

Sensing Sound And Space:Auditory And Visual Spatial ImpressionIn Three Auditoria

Nguyen, Andy January 2005 (has links)
In some contexts, the experience of sound and space are often considered as two unrelated experiences. In an auditorium, the senses of hearing and seeing are not necessary unrelated. This thesis proposes that there is a sensorial relationship between sound and space in the context of symphonic concert halls. Through a study of three auditoria, this thesis explores the relationship, and the degree of correspondence and interaction between auditory and visual spatial impression. It begins by exploring the concepts of auditory and visual spatial impression in relation with auditorium acoustics and architectural design. In auditorium acoustics, a number of terms are used to describe auditory spatial impression, such as �spaciousness,� �envelopment,� and �intimacy.� These terms have connotations beyond the auditory. The thesis suggests that they may also be used to describe visual spatial impression in auditoria. Through textual analyses, the thesis finds that the auditory and visual terms do not always relate to the same physical characteristics of auditoria and can conflict with one another. Hence, it is apparent that further subjective analyses of auditory and spatial impression are needed. Three chapters in this thesis are devoted to auditory and visual subjective experiments. Their purpose is to explore the degree of correspondence or contrast, and interaction between auditory and visual spatial impression. The degree of correspondence and contrast between auditory and visual spatial impression appear to vary between auditoria and within auditoria. The relationship between auditory and visual spatial impression appear to be both necessary and arbitrary, and the degree of interaction between them appear to be strong in some cases and weak in other. From the findings, this thesis suggests that the degree of correspondence or contrast, and interaction between auditory and visual spatial impression could be used to create an audiovisual experience that suit specific musical events. Concert auditoria are culturally and artistically unique spaces. Hence, consideration must be taken to understand the relationships between, and intentions of the acoustical and architectural designs, music and architecture, for a successful and creative collaboration between designers - since the ultimate goal is to create an extraordinary audiovisual experience in a concert hall.
