Organizational Energy: A Behavioral Analysis of Human and Organizational Factors in Manufacturing

Irani, Zahir, Sharif, Amir M., Papadopoulos, T. 03 June 2015 (has links)
Yes / This paper seeks to explore the behavior and embodied energy involved in the decision-making of information technology/information systems (IT/IS) investments using a case within a small- to medium-sized manufacturing firm. By analyzing decision making within a given case context, this paper describes the nature of the investment through the lens of behavioral economics, causality, input-output (IO) equilibrium, and the general notion of depletion of executive energy function. To explore the interplay between these elements, the authors structure the case context via a morphological field in order to construct a fuzzy cognitive map of decision-making relationships relating to the multidimensional and nonquantifiable problems of IT/IS investment evaluation. Noting the significance of inputs and outputs relating to the investment decision within the case, the authors assess these cognitive interrelationships through the lens of the Leontief IO energy equilibrium model. Subsequently, the authors suggest, through an embodied energy audit, that all such management decisions are susceptible to decision fatigue (so-called “ego depletion”). The findings of this paper highlight pertinent cognitive and IO paths of the investment decision-making process that will allow others making similar types of investments to learn from and draw parallels from such processes.

Does Cognitive Leadership Matter? : An Analysis of Tony Blair’s Decision on the Iraq War

Olsson, Moa January 2019 (has links)
By using a qualitative content analysis and cognitive mapping, the purpose of the thesis is to investigate the decision-making of political leaders in extraordinary situations. The thesis focuses on the case of Tony Blair and his decision to invade Iraq in 2003. The cognitive map of political elites by Robert Axelrod is used to form a cognitive map to illustrate and represent the beliefs of Blair. The research question is what formed Blair’s decision to invade Iraq in 2003? Three time periods are analyzed: before, during and after the war. The results show that intervention should be accepted and no intervention should be rejected. This is with regard to the British utility. The motives for the intervention was Blair’s belief in spreading democratic values and rights. Something which would generate stability and progress for Britain, as well as, for other countries. To end human suffering, WMD trade and terrorism were also among the motives for the intervention. To strengthen the strategic relationship with Russia through intervention was important and the relationship with the U.S. even more. No intervention would increase the ineffective containment and strengthen the regime of Hussein. No intervention would also increase WMD (trade, development and use), terrorism, destruction and people suffering and dying on a mass-scale. Altogether this would negatively impact the British utility.

The Untimely-Image : On Contours of the New in Political Film-Thinking

Nilsson, Jakob January 2012 (has links)
This study creates and develops a concept called the untimely-image including two sub-concepts called contours of the new and the untimely-site. The untimely-image concerns the clearing for and the expression of figures of “potential” in thought in the form of moving-images. The aim of these concepts is to form a critical framework for evaluating and conceptualizing political film as expressive, not of the new itself but of its “untimely” contours. The untimely-image, and its many implications, is developed over the course of six chapters. Chapter 1 extensively defines “contours” and “new” as operative in this study, and also introduces a theme that runs through all the chapters: how to think the contours of the new in relation to the cult of the new in consumer culture and in relation to the larger mechanisms of advanced capitalism. Chapter 2 defines the parameters of the untimely-image as specifically regarding moving images, and continues the development of this concept. In Chapters 3 to 6, The Wire (David Simon, 2002-2008) serves the double function of complicating and giving specification to the elaboration of the untimely-image as well as a case in which the untimely-image is used as a critical framework. The Wire and the untimely-image relate in processes of juxtaposition, wherein they meet, cross over, separate, and reproblematize each other. An untimely-image is fully defined in relation to concrete political issues. The untimely-image is therefore advanced by articulating the components and characteristics that, independently of the concrete issue, remain in every case, as well as by putting the concept to work regarding two specific problems in The Wire: its expression of blackness and its mapping of advanced capitalism.

Navigation spatiale en milieu urbain réel ou virtuel : performances et traitement multisensoriel de l'information spatiale chez les voyants, malvoyants et aveugles congénitaux ou tardifs / Spatial navigation in real and virtual urban environments : performance and multisensory processing of spatial information in sighted, visually impaired, late and congenitally blind individuals

Boumenir, Yasmine 29 September 2011 (has links)
Dans le cadre de cette thèse, nous avons mené trois études sur le terrain et/ou en laboratoire pour comparer l'importance relative de la géométrie des routes, représentée visuellement ou tactilement en deux dimensions, des informations multidimensionnelles extraites sur la base d'une visite directe du monde réel, et des informations symboliques indirectes sur les lieux par le biais d' instructions verbales, dans la construction de représentations spatiales chez l'homme, lui permettant de naviguer de mémoire dans des environnements complexes et non-familiers. Ces expériences ont permis de mettre en lumière certains aspects multidimensionnels et multi-sensoriels dans le traitement cognitif des informations spatiales et l'influence de celui-ci sur les performances d'hommes et de femmes, qui avaient pour tâche de retrouver de mémoire un itinéraire donné dans un milieu urbain non familier. Les résultats montrent clairement que des informations relatives aux repères visuels, transmises au moyen de séquences d'images panoramiques des itinéraires étudiés, sont inutilisables par un navigateur s'il ne dispose pas d'informations valides sur les distances relatives entre ces repères dans le monde réel (expérience 1). L'influence d'une exposition au préalable à un plan 2D visuel ou tactile des itinéraires a été comparé avec celle d'une expérience directe au moyen d'une visite guidée, ou indirecte au moyen d'indications verbales, sur les performances de navigation de personnes voyantes (expérience 1 et 2), déficientes visuelles (expérience 3), ou voyantes mais privées temporairement de leur vision (expérience 3) dans des environnements urbains à grande échelle. Les tests ont été réalisés en milieu réel (expériences 1 et 3) et virtuel (expérience 2) généré par ordinateur (Google Street View). Les performances ont été analysées en termes de temps du point de départ au point d'arrivée, nombre d'arrêts, nombre d'erreurs et taux de succès. Les stratégies potentiellement employées durant la navigation sont mis en avant sur la base des réponses des sujets à un questionnaire standardisé ; leurs capacités individuelles de se représenter l'environnement exploré sous forme d'images mentales a été évaluée sur la base de dessins. Les niveaux subjectifs de stress psychologique ont été mesurés pour mettre en évidences des différences possibles entre l'homme et la femme à cet égard. Les données ici montrent, d'une part, qu'une exploration rapide de représentations virtuelles correctement mises à l'échelle d'un environnement complexe permet aux sujets de retrouver cet itinéraire sans problème dans le milieu réel (expérience 2). Les personnes aveugles de naissance compensent l'absence de repères visuels dans la navigation efficacement par la mémorisation d'informations géométriques sur la base d'une brève exploration d'un plan tactile des itinéraires étudiés ici. Les sujets voyants privés de repères visuels, par contre, ne sont pas instantanément capables d'une telle compensation (expérience 3). Les résultats de ce travail sont discutés ici à la lumière des hypothèses actuelles sur la nature intrinsèque des représentations spatiales chez l'homme et placés ici dans le contexte d'un modèle de la mémoire de travail. Nous suggérons que cette dernière comprend des sous-systèmes multidimensionnels de stockage temporaire, capables de traiter en parallèle une multitude d'entrées sensorielles avec une capacité beaucoup plus grande que précédemment postulé dans le modèle classique de la mémoire de travail, qui présume un traitement sériel d'informations à capacité limitée. Un tel modèle est globalement mis en question par les résultats de cette thèse, qui ouvre une porte importante aux recherches futures sur le traitement cognitif d'informations spatiales chez l'homme dans un monde en perpétuel changement.Mots-clés : Environnements à grandes échelles – perception – traitement multi-sensoriel – représentation spatiale – navigation – humain / Previous studies investigating how humans build reliable spatial knowledge representations allowing them to find their way from one point to another in complex environments have been focused on comparing the relative importance of the two-dimensional visual geometry of routes and intersections, multi-dimensional data from direct exposure with the real world, or verbal symbols and/or instructions. This thesis sheds further light on the multi-dimensional and multi-sensorial aspects by investigating how the cognitive processing of spatial information derived from different sources of sensory and higher order input influences the performance of human observers who have to find their way from memory through complex and non-familiar real-world environments. Three experiments in large-scale urban environments of the real world, and in computer generated representations of these latter (Google Street View), were run to investigate the influence of prior exposure to 2D visual or tactile maps of an itinerary, compared with a single direct experience or verbal instructions, on navigation performances in sighted and/or visually deficient individuals, and in individuals temporarily deprived of vision. Performances were analyzed in terms of time from departure to destination, number of stops, number of wrong turns, and success rates. Potential strategies employed by individuals during navigation and mental mapping abilities were screened on the basis of questionnaires and drawing tests. Subjective levels of psychological stress (experiment 2) were measured to bring to the fore possible differences between men and women in this respect. The results of these experiments show that 2D visual maps, briefly explored prior to navigation, generate better navigation performances compared with poorly scaled virtual representations of a complex real-world environment (experiment 1), the best performances being produced by a single prior exposure to the real-world itinerary. However, brief familiarization with a reliably scaled virtual representation of a non-familiar real-world environment (Google Street View) not only generates optimal navigation in computer generated testing (virtual reality), but also produces better navigation performances when tested in the real-world environment and compared with prior exposure to 2D visual maps (experiment 2). Congenitally blind observers (experiment 3) who have to find their way from memory through a complex non-familiar urban environment perform swiftly and with considerable accuracy after exposure to a 2D tactile map of their itinerary. They are also able to draw a visual image of their itinerary on the basis of the 2D tactile map exposure. Other visually deficient or sighted but blindfolded individuals seem to have greater difficulty in finding their way again than congenitally blind people, regardless of the type of prior exposure to their test itinerary. The findings of this work here are discussed in the light of current hypotheses regarding the presumed intrinsic nature of human spatial representations, replaced herein within a context of working memory models. It is suggested that multi-dimensional temporary storage systems, capable of processing a multitude of sensory input in parallel and with a much larger general capacity than previously considered in terms of working memory limits, need to be taken into account for future research.Keywords: large scale environments – perception – multisensory processing - spatial representation – navigation - human

Makroregionální struktury světa: reprezentace, percepce a objektivizace / Macroregional structures of the world: representation, preception, and objectivisation

Polonský, Filip January 2012 (has links)
The thesis brings insight to the problem of geosocietal differentiation of the world and its interpretation in the schemes of (major) world regional structures. These schemes are matter of different presentation and representation and have utility in organization of both scientific and non-scientific practices. A more detailed analysis and discussion of academic approaches to global macroregionalization was provided, which was followed by an analysis of the views of so-called global actors. Assessed was also situation in Czech and Slovak education (geographical textbooks). Perceptions of regional schemes are represented by views of geography students. Struggles with objectification were related to several-variant-based consideration of internal homogeneity and external heterogeneity of macroregions. Also assessed were world economic flows, distribution of integrated power potential and its development (1950 - 2008). Conclusions bring synthesis of the findings, as well as an outline of possible future research topics.

La compensation des impacts sociaux et écologiques pour les projets d'aménagement : acceptation, perceptions et préférences des acteurs du territoire. Application au projet de parc éolien en mer de la baie de Saint-Brieuc (Bretagne,France) / Compensation for social and ecological impacts of development project : acceptance, perceptions and preferences of local stakeholders. Application of the projected offshore wind farm of the Bay of Saint-Brieuc

Kermagoret, Charlène 17 December 2014 (has links)
Les politiques de développement durable ont fait émerger de nombreux outils qui visent à concilier les enjeux de développement économique et ceux de préservation des intérêts sociaux et environnementaux. Parmi eux, la compensation territoriale se matérialise par l’attribution, à un territoire subissant les impacts négatifs d’un aménagement déclaré d’utilité publique, d’un ensemble de mesures visant à maintenir à niveau acceptable le bien-être des individus et l’état écologique du milieu. Elle permet ainsi de rétablir un équilibre entre la dimension globale du projet, qui ne considère que ses effets positifs, et la dimension locale, dans laquelle les externalités positives et négatives du projet rentrent en jeu. Initié par un questionnement sur la mise en oeuvre d’un tel outil de politique publique au sein de territoires spécifiques, l’objectif principal de ce travail est de caractériser la demande de compensation par les acteurs du territoire au regard des impacts perçus dans un contexte de projet d’aménagement. Ce travail explore les perceptions des acteurs du territoire de la baie de Saint-Brieuc directement concernés par un projet de parc éolien en mer vis-à-vis de ce principe de compensation. Pour ce faire, des approches qualitatives et quantitatives ont été utilisées de manière complémentaire et font appel à des outils spécifiques tels que la cartographie cognitive floue et la méthode des choix expérimentaux. Cette démarche nous a permis de produire de nombreux éléments de compréhension quant à la manière dont ces acteurs perçoivent les impacts d’un tel projet d’aménagement, acceptent ou non le principe de compensation comme outil de réponse aux impacts négatifs du projet et envisagent la mise en oeuvre de la compensation à travers leurs préférences vis-à-vis de différentes types d’actions – indemnisations financières, investissements dans des biens communs, restauration écologique. Les résultats de ce travail montrent que les perceptions, très hétérogènes au sein des acteurs du territoire, s’expliquent en grande partie à travers le concept de Communautés de Pratiques. Finalement, lorsque le principe de compensation est accepté par les acteurs du territoire, la logique d’équivalence qui conditionne la demande de compensation peut s’expliquer de trois manières différentes : une équivalence territoriale dans laquelle les bénéfices issus de la compensation doivent profiter à l’ensemble de la population du territoire impacté ; une équivalence écologique dans laquelle le niveau de fonctions écologiques et de services écosystémiques est maintenu constant, une équivalence basée sur des valeurs économiques pour pallier le manque à gagner de certaines activités professionnelles. / In the context of a territory suffering from the negative impacts of an infrastructure declared of public utility, territorial compensation consists of a set of measure that aims to help maintaining the level of well-being of each and every individual as well as a desirable ecological state. This way, territorial compensation allows to balance between the global scale of the project, in which only the positive impacts are taken into account, and the local scale where both positive and negative externalities of the project are running. Initiated by a questioning on how such a public policy tool can be deployed at the heart of specific territories, the main objective of this PhD work is to characterize the expectation of local stakeholders towards the perceived impacts awaited from the instatement of a development project. More specifically, this work relies on an analytical approach centered on the study of the perception of the stakeholders of the Bay of St-Brieuc territory (Western Brittany, France), who are directly concerned by an offshore wind farm project. To reach suchaims, complementary qualitative and quantitative methods are used such as fuzzy cognitive mapping and choice experiment method. Using this kind of approaches allowed us to better define several keys for understanding how local stakeholders perceive the impacts of such a project and agree or not with compensation being an appropriate answer regarding the negative impacts of the project and consider the implementation of compensation in reference to their preferences towards different types of action – monetary incentives, public goods investments, ecological restoration. Our results show very heterogeneous perceptions in between the different stakeholders that can in a large part beexplained using the concept of Communities of Practice. Finally, when the principle of compensation is accepted by allthe stakeholders of a territory, the equivalency logical that determines the compensation expectations can be of three types: a territorial equivalency, in which the benefits of compensation must be shared by all inhabitants of the impacted territory; an ecological equivalency, in which the level of ecological functions or ecosystem services is maintained constant; and an equivalency based on economic values that must balance the loss of benefits underwent by some professional activities.
