Les composantes du risque : une entrée par les acteurs et le conflit lors de la mise en place des solutions : le cas de Los Chorros, Guatemala

Ce travail présente une étude de cas post-catastrophe à San Cristobal, Guatemala, où un important glissement de terrain du nom «Los Chorros» (8-10 millions de m3 de roche) affecte depuis 2009 diverses communautés et une des routes principales du pays. Les gestionnaires des risques, sur la base de leur propre évaluation, ont décidé de répondre d'une manière qui ne correspond pas aux intérêts de la population affectée. Les communautés locales ont évalué le risque de catastrophe et ont établi une autre solution suivant une conception du risque différente. Les conflits sociaux et la concurrence entre les différents acteurs du territoire, pour la définition des priorités et des solutions, révèlent les aspects sous-jacents de la société, utiles pour identifier et comprendre ce qui constitue le risque de catastrophe dans un contexte donné. Ce conflit montre que le risque de catastrophe n'est pas univoque mais un concept complexe, constitué par un grand nombre de composants. En termes de gouvernance, il met également en évidence la confrontation des savoirs et la tension qui peut exister entre les différentes approches du risque. Depuis une approche où le risque de catastrophe est considéré comme une construction sociale (les vulnérabilités étant historiquement générées par des processus sociaux, politiques, économiques et culturels), ce travail évalue d'autres modes d'interprétation, de traitement et d'intervention qui peuvent aider à améliorer les méthodes d'évaluation et de gestion des risques. Enfin, la proposition de gestion qui découle de l'exemple guatémaltèque invite à une autre manière de concevoir la gestion des risques en intégrant les différentes conceptions du risque et en visant une coordination stratégique entre les acteurs des politiques publiques, les échelles d'intervention, les experts en charge des différents aléas et la société civile, afin d'obtenir une solution acceptable pour tous les acteurs impliqués dans un territoire. -- This work analyses a post-disaster case study from San Cristobal, Guatemala where a large landslide named "Los Chorros (8 millions cubic meters of rock) affects several communities and one of the country's main west-east access highways. Risk managers, starting from their own assessment, decided to respond in a way that does not correspond to the interests of the afected population. Local communities assessed the risk disaster situation and establised another solution from a different conception of risk. These social conflict and competition for priorities and solutions for risk management reveal that disaster risk is not unequivocal but a complex and holistic concept, constituted by a large set of components. From a social constructivism approach, where disaster risk is considered as the results of social, political, economic and historic process, this thesis evaluates other modes of interpreting, shaping and managing risk that can help improve methods of risk assessment and management. Studying the logic of action of actors, who mobilize to establish a solution, enables to identify as to what constitutes a disaster. For this reason, the study focus, in particular, on the analysis of practices (practical science) implemented by all actors in San Cristobal Altaverapaz. Finally, it puts into perspective the risk management in terms of an integrative approach for policy experts that find compromise between different conceptions of risk in order to obtain a solution acceptable to all those involved.

Three essays in behavioral and experimental economics

The present PhD dissertation consists of three papers, organized in chapters, in the field of behavioral economics. This discipline studies economic behavior of individuals subject to limitations, such as bounded self-interest and bounded willpower. The behavior studied in the present thesis ranges from the complex decision to register as an organ donor, decision¬making in the presence of uncertainty and the decision to give money to a charitable organization. The first chapter aims at testing the effectiveness of an active-decision (AD) mechanism on the decision to become an organ donor in Switzerland, using field experiments. We found that stimulating participants' reflection on the topic of organ donation had a negative effect on the decision to become an organ donor. Moreover, a non-binding commitment nudge reduces putting off the decision, but does not lead to donation rates higher than in the control group. The results suggest that AD may be far more limited than previously thought and raise doubts about the efficacy of engaging potential donors to reflect on the topic of organ donation. Beyond carrying for others, behavioral economics also recognizes that individuals do not evaluate outcomes in absolute terms but rather by comparing them to some reference levels, called reference points. Above the reference points, economic outcomes are perceived as gains, while below these levels the same outcomes are felt as losses. The last two chapters analyze the importance of reference points in the evaluation of economic outcomes. Using a laboratory experiment where subjects played two consecutive lotteries, Chapter 2 studies the speed of adjustment of the reference point. We find that varying the probability of winning the first lottery has no effect on subjects' risk behavior regarding the second lottery. This result indicates a very fast adjustment of the reference point to the latest information. Chapter 3 investigates whether reference points are relevant for charitable preferences. Using actual donation decisions of participants in a laboratory experiment, the results suggest that reference points are not crucial for shaping charitable giving. -- Cette thèse de doctorat consiste en trois articles, organisés en chapitres, dans le domaine de l'économie comportementale. Cette discipline étudie le comportement d'agents économiques sujets à des limitations, telles qu'un égoïsme limité et une volonté limitée. Le comportement étudié dans cette thèse va de la décision complexe de devenir donneur d'organes, la prise de décision en présence d'incertitude à la décision de donner de l'argent à une oeuvre caritative. Le premier chapitre vise à tester l'efficacité d'un mécanisme de « décision active » (active decision, AD) sur la décision de devenir donneur d'organes en Suisse, et ce en recourant à deux expériences hors-laboratoire. Les résultats montrent que stimuler la réflexion des participants sur le don d'organes a un effet négatif sur la décision de devenir donneur. De plus, un mécanisme qui encourage les participants à prendre une décision sur le champ réduit la tendance à procrastiner, mais ne mène pas à un taux de donneurs plus élevé par rapport à un groupe de contrôle. Les résultats suggèrent que le mécanisme AD est bien plus limité que ce qui a été supposé jusqu'à maintenant. De plus, ils suscitent le doute quant à l'efficacité de stimuler la réflexion de potentiels donneurs sur le sujet du don d'organes. En plus de se soucier des autres, l'économie comportementale admet également que les individus n'évaluent pas les résultats de façon absolue, mais en comparant ceux-ci à des niveaux de références, souvent appelés points de référence. Au-dessus de ces points de référence, les résultats sont perçus en tant que gains, tandis qu'en-dessous ces mêmes résultats sont considérés comme des pertes. Les deux derniers chapitres analysent l'importance des points de référence dans diverses situations. A l'aide d'une expérience en laboratoire dans laquelle les participants participent à deux loteries consécutives, le chapitre 2 étudie la vitesse d'ajustement du point de référence. Le résultat montre que varier la probabilité de gagner la première loterie n'a aucun effet sur le comportement en matière de risques concernant la deuxième loterie. Cela indique un ajustement très rapide du point de référence. Le chapitre 3 vise à déterminer si les points de référence ont un rôle majeur concernant les préférences caritatives. Les données relatives aux décisions de don des participants d'une expérience en laboratoire montrent que les points de référence n'influencent pas significativement le don caritatif.

Offshore Sourcing in Software Development: Case Studies of Finnish-Russian Cooperation

The study examines international cooperation in product development in software development organisations. The software industry is known for its global nature and knowledge-intensity, which makes it an interesting setting to examine international cooperation in. Software development processes are increasingly distributed worldwide, but for small or even medium-sized enterprises, typical for the software industry, such distribution of operations is often possible only in association with crossing the company’s boundaries. The strategic decision-making of companies is likely to be affected by the characteristics of the industry, and this includes decisions about cooperation or sourcing. The objective of this thesis is to provide a holistic view on factors affecting decisions about offshore sourcing in software development. Offshore sourcing refers to a cooperative mode of offshoring, where a firm does not establish its own presence in a foreign country, but utilises a local supplier. The study examines product development activities that are distributed across organisational and geographical boundaries. The objective can be divided into two subtopics: general reasons for international cooperation in product development and particular reasons for cooperation between Finnish and Russian companies. The focus is on the strategic rationale at the company level, in particular in small and medium-sized enterprises. The theoretical discourse of the study builds upon the literature on international cooperation and networking, with particular focus on cooperation with foreign suppliers and within product development activities. The resource-based view is also discussed, as heterogeneity and interdependency of the resources possessed by different firms are seen as factors motivating international cooperation. Strategically, sourcing can be used to access resources possessed by an industrial network, to enhance the product development of a firm, or to optimise its cost structure. In order to investigate the issues raised by the theoretical review, two empirical studies on international cooperation in software product development have been conducted. The emphasis of the empirical part of the study is on cooperation between Finnish and Russian companies. The data has been gathered through four case studies on Finnish software development organisations and four case studies on Russian offshore suppliers. Based on the material from the case studies, a framework clarifying and grouping the factors that influence offshore sourcing decisions has been built. The findings indicate that decisions regarding offshore sourcing in software development are far more complex than generally assumed. The framework provides a holistic view on factors affecting decisions about offshore sourcing in software development, capturing the multidimensionality of motives for entering offshore cooperation. Four groups of factors emerged from the data: A) strategy-related aspects, B) aspects related to resources and capabilities, C) organisation-related aspects, and D) aspects related to the entrepreneur or management. By developing a holistic framework of decision factors, the research offers in-depth theoreticalunderstanding of offshore sourcing rationale in product development. From the managerial point of view, the proposed framework sums up the issues that a firm should pay attention to when contemplating product development cooperation with foreign suppliers. Understanding different components of sourcing decisions can lead to improved preconditions for strategising and engaging in offshore cooperation. A thorough decisionmaking process should consider all the possible benefits and risks of product development cooperation carefully.

An fMRI Study of Emotional engagement in decicion-making

It has been suggested that decisionmaking depends on sensitive feelings associatedwith cognitive processing rather than cognitiveprocessing alone. From human lesions, we knowthe medial anterior inferior-ventral prefrontalcortex processes the sensitivity associated withcognitive processing, it being essentiallyresponsible for decision making.In this fMRI (functional Magnetic ResonanceImage) study 15 subjects were analyzed usingmoral dilemmas as probes to investigate the neuralbasis for painful-emotional sensitivity associatedwith decision making. We found that a networkcomprising the posterior and anterior cingulateand the medial anterior prefrontal cortex wassignificantly and specifically activated by painfulmoral dilemmas, but not by non-painful dilemmas.These findings provide new evidence that thecingulate and medial anterior prefrontal areinvolved in processing painful emotionalsensibility, in particular, when decision makingtakes place. We speculate that decision makinghas a cognitive component processed by cognitivebrain areas and a sensitivity component processedby emotional brain areas. The structures activatedsuggest that decision making depends on painfulemotional feeling processing rather than cognitiveprocessing when painful feeling processinghappens

Tuotantostrateginen päätöksenteko yrityksissä

Tuotantostrategisia päätöksiä, tässä tutkimuksessa erityisesti ulkoistamis-, verkostoitumis- ja ulkomaille laajentamispäätöksiä, tehdään yrityksissä jatkuvasti nykyisessä dynaamisessa liiketoimintaympäristössä. Tuotantostrategisen päätöksenteon jäljet ovat pitkälle johtavia ja päätöksenteossa tehdyt virheet voivat siksi olla yrityksille todella haavoittavia. Tutkimuksen tavoitteena on kuvata nykyistä tuotantostrategista päätöksentekoa suomalaisissa kone- ja metalliteollisuuden pk-yrityksissä. Kirjallisuudesta ja aikaisemmista tutkimuksista muodostetaan teoriapohja tuotantostrategisesta päätöksenteosta ja tunnetuimmista päätöksentekotyökaluista. Empiirinen aineisto koostuu asiantuntija- ja yrityshaastatteluista. Sekä teoriassa että empiriassa tuotantostrategista päätöksentekoa pidetään viime kädessä ylimmän johdon osaamis- ja vastuualueena. Teoria näkee päätöksenteon koko henkilöstön sitovana prosessina, jossa apuna käytetään taloudellisten menetelmien lisäksi myös muita työkaluja. Haastattelujen perusteella päätöksentekovaiheista ei yrityksissä ole olemassa kirjallista kuvausta ja päätökset tehdään hallituksessa tai johtoryhmässä nopeasti ja pääasiassa taloudellisiin menetelmiin nojaten.

Tuotantostrateginen Make or buy -päätöksenteko metalliteollisuusalan yrityksessä

Tuotantostrategiaan perustuvien ostaa-valmistaa, eli Make or buy -päätösten merkitys on korostunut yritysten dynaamisen toimintaympäristön myötä. Päätöksissä tehdyt virheet voivat olla kohtalokkaita yrityksen kilpailukyvylle. Diplomityön tavoitteena on luoda Make or buy -päätöksentekoa ohjaava viitekehys yrityksen kansainväliseen käyttöön. Tavoitteeseen sisältyy luodun Make or buy -mallin toimivuuden todentaminen case-tutkimuksella. Make or buy -päätöksenteossa korostuvat talouden, osaamisen ja riskien näkökulmat. Tehtyjä päätöksiä tulee uudelleenarvioida ja tarvittaessa päivittää toimintaympäristön muuttuessa. Päätöksentekomallin tulee siis olla toistuvaa käyttöä ajatellen selkeä ja helppokäyttöinen. Työssä kehitetty kirjallisuusaineistoon perustuva Make or buy –päätöksenteon viitekehys ohjaa yritystä strategisen, taktisen ja operatiivisen tason päätöksissä. Lisäksi malli ohjaa organisaatiota päätöksentekoroolien määrittämisessä. Viitekehys sisältää strukturoidun päätöksentekomallin strategisiin ja taktisiin päätöksiin sekä yksinkertaisen valintamallin operatiivisiin päätöksiin. Operatiivisen tason eriyttämisellä pyritään helpottamaan mallien käyttöä. Työssä rakennetun strukturoidun viitekehyksen toimivuuden testaus esitetään empiirisessä vaiheessa.

Operatiivisen tason suorituskyvyn mallimittariston kehittäminen logistiikkapalveluyritykselle

Tutkimuksen tavoitteena oli kehittää mallimittaristo logistiikkapalvelualalla toimivan yrityksen operatiivisen tason suorituskyvyn seurantaan ja toiminnanohjausta varten, päivittäisen johtamisen tueksi. Tutkimus suoritettiin pääosin toiminta-analyyttisena, yhden yrityksen empiirisenä tapaustutkimuksena. Tutkimuksen kohdeyrityksen toiminnanmittaus perustuu tällä hetkellä pääasiassa taloudellisiin mittareihin ja muutamaan kyselyyn. Toiminnanohjauksen ja – kehittämisen, päätöksenteon tueksi tarvitaan, taloudellisten mittareiden lisäksi, mittareita, joilla pystytään seuraamaan suorituskyvyn taustalla vaikuttavien tekijöiden kehittymistä. Tutkimuksen kohdeyrityksen operatiivisen tason suorituskyvyn mallimittariston suunnittelussa haluttiin varmistaa, että jatkossa mittaamisella vaikutettaisiin seuraustekijöiden lisäksi myös syytekijöihin, selkiyttää liiketoiminnan tavoitteet, operatiivisen tason näkökulmasta, ja mittaamisen tavoite. Tutkimuksessa esitelty mallimittaristo on suunniteltu, tasapainotetun mittariston viitekehyksen avulla. Mittariston näkökulmiksi valittiin: talous, sidosryhmä (asiakas), prosessi ja henkilöstö. Mittariston tuottaman tiedon tavoitteena on toiminnanohjauksen, -kehittämisen ja päätöksenteon tukeminen, kun mittaustulokset ja trendi ovat yhdessä paikassa, on tiedonhaku ja - hyödyntäminen helpompaa. Mallimittaristoa ei testattu eikä käyttöönotettu tutkimuksessa.

Impact of Word-of-Mouth on consumer decision-making: An information processing perspective in the context of a high-involvement service

This doctoral study conducts an empirical analysis of the impact of Word-of-Mouth (WOM) on marketing-relevant outcomes such as attitudes and consumer choice, during a high-involvement and complex service decision. Due to its importance to decisionmaking, WOM has attracted interest from academia and practitioners for decades. Consumers are known to discuss products and services with one another. These discussions help consumers to form an evaluative opinion, as WOM reduces perceived risk, simplifies complexity, and increases the confidence of consumers in decisionmaking. These discussions are also highly impactful as WOM is a trustworthy source of information, since it is independent from the company or brand. In responding to the calls for more research on what happens after WOM information is received, and how it affects marketing-relevant outcomes, this dissertation extends prior WOM literature by investigating how consumers process information in a highinvolvement service domain, in particular higher-education. Further, the dissertation studies how the form of WOM influences consumer choice. The research contributes to WOM and services marketing literature by developing and empirically testing a framework for information processing and studying the long-term effects of WOM. The results of the dissertation are presented in five research publications. The publications are based on longitudinal data. The research leads to the development of a proposed theoretical framework for the processing of WOM, based on theories from social psychology. The framework is specifically focused on service decisions, as it takes into account evaluation difficulty through the complex nature of choice criteria associated with service purchase decisions. Further, other gaps in current WOM literature are taken into account by, for example, examining how the source of WOM and service values affects the processing mechanism. The research also provides implications for managers aiming to trigger favorable WOM through marketing efforts, such as advertising and testimonials. The results provide suggestions on how to design these marketing efforts by taking into account the mechanism through which information is processed, or the form of social influence.

Gendered attitudes and family planning decision-making in Honduras

This study examines gendered attitudes and family planning in the Central American country of Honduras using a feminist perspective. Specifically, this study investigates the relationships between gendered attitudes (i.e., male oriented or non-male oriented attitudes) and who makes decisions about contraceptive use and family size among married and common-law Hondurans. This study also attempts to account for social elements such as gendered attitudes, education, economics, environment and demographics that may act to limit or enhance women's agency in reproductive decisionmaking. Furthermore, gender is examined to determine whether these relationships depend on the gender of the respondents. Two national Honduran surveys from 2001 are used in a secondary analysis, specifically muUinomial logisfic regression. Findings indicate that women reporting non-male oriented attitudes are significantly more likely to indicate that they (the wives) make the contraceptive decisions. Moreover, both men and women reporting non-male oriented attitudes are significantly more likely to indicate making contraceptive decisions together. Both of these effects remain significant when other social factors included in the analyses, though part of the effect is explained by education and economics. Similar effects are found in terms of family size decisions. Limitations and directions for future research are discussed.

An exploration of women elementary school teachers' perceptions of how their decision to return to teaching part-time from a maternity leave influences their professional and personal lives /

The purpose of this research was to explore women elementary teachers' perceptions of how their decision to return to teaching part-time from a maternity leave influences their professional and personal lives. The investigation focused on the decisions surrounding a mother's choice to reenter the teaching profession parttime in a field where each mother had previously been employed full-time. A collective case study was undertaken based on an in-depth interview with five mothers who had made the choice to return to the classroom part-time. The data collected in this study were analyzed and interpreted using qualitative methods. The following four major themes emerged from the interviews: decisionmaking process, challenges faced by mothers who teach part-time, the importance of support, and the enhancement of instructional practice from parenthood. Using these four themes, an analysis was conducted to examine the similarities and differences among the experiences of the participants. The mothers' reflections, my analysis, and the related literature were used at the conclusion of this report to compile implications for teaching practice, theory, and further research.

Job satisfaction among nurses and its relationship to reflective practice /

This study was undertaken to explore job satisfaction among nurses and its relationship to reflective practice. It is a qualitative study that listens to the perspectives of 7 mental health nurses who work In a conmiunity hospital in southern Ontario. A pilot survey was conducted prior to the face-to -face interviews in order to develop meaningful questions to utilize in the interviews. Nurses participating in the study were ensured anonjnnlty and an opportunity to have their own personal perspectives heard. A convenient sample was obtained from the hospital in which the researcher worked as an educator and professional practice consultant. The concept of job satisfaction was found to be driven by the desire to do important work and to make a difference in patients' lives. The nurses articulated that it is directly related to other factors, such as the opportunity to work in one's area, of preference, involvement in decisionmaking processes, better patient/ staff ratios, and affordable, accessible continuing educational opportunities. Those nurses who have embraced reflective practice for many years seem to be able to sort out that which drives them to stay in nursing and that which will influence them to leave. The constraints of the study cO-e that it is a small qualitative study; therefore, the results are not generallzable. Reflection is integral to the practice of mental heallth nursing find a tool that is used extensively in therapy with patients. Future research could involve studing a different group of nurses who may be more task focused than mental health nurses.

Évaluation et amélioration du rendement de la formation en entreprise : vers une démarche basée sur la gestion des processus d’affaires.

La formation est une stratégie clé pour le développement des compétences. Les entreprises continuent à investir dans la formation et le développement, mais elles possèdent rarement des données pour évaluer les résultats de cet investissement. La plupart des entreprises utilisent le modèle Kirkpatrick/Phillips pour évaluer la formation en entreprise. Cependant, il ressort de la littérature que les entreprises ont des difficultés à utiliser ce modèle. Les principales barrières sont la difficulté d’isoler l’apprentissage comme un facteur qui a une incidence sur les résultats, l’absence d’un système d’évaluation utile avec le système de gestion de l’apprentissage (Learning Management System - LMS) et le manque de données standardisées pour pouvoir comparer différentes fonctions d’apprentissage. Dans cette thèse, nous proposons un modèle (Analyse, Modélisation, Monitoring et Optimisation - AM2O) de gestion de projets de formation en entreprise, basée sur la gestion des processus d’affaires (Business Process Management - BPM). Un tel scénario suppose que les activités de formation en entreprise doivent être considérées comme des processus d’affaires. Notre modèle est inspiré de cette méthode (BPM), à travers la définition et le suivi des indicateurs de performance pour gérer les projets de formation dans les organisations. Elle est basée sur l’analyse et la modélisation des besoins de formation pour assurer l’alignement entre les activités de formation et les objectifs d’affaires de l’entreprise. Elle permet le suivi des projets de formation ainsi que le calcul des avantages tangibles et intangibles de la formation (sans coût supplémentaire). En outre, elle permet la production d’une classification des projets de formation en fonction de critères relatifs à l’entreprise. Ainsi, avec assez de données, notre approche peut être utilisée pour optimiser le rendement de la formation par une série de simulations utilisant des algorithmes d’apprentissage machine : régression logistique, réseau de neurones, co-apprentissage. Enfin, nous avons conçu un système informatique, Enterprise TRaining programs Evaluation and Optimization System - ETREOSys, pour la gestion des programmes de formation en entreprise et l’aide à la décision. ETREOSys est une plateforme Web utilisant des services en nuage (cloud services) et les bases de données NoSQL. A travers AM2O et ETREOSys nous résolvons les principaux problèmes liés à la gestion et l’évaluation de la formation en entreprise à savoir : la difficulté d’isoler les effets de la formation dans les résultats de l’entreprise et le manque de systèmes informatiques.

The Effect of SIFT Features as Content Descriptors in the Context of Automatic Writer Identification in Malayalam Language

The span of writer identification extends to broad domes like digital rights administration, forensic expert decisionmaking systems, and document analysis systems and so on. As the success rate of a writer identification scheme is highly dependent on the features extracted from the documents, the phase of feature extraction and therefore selection is highly significant for writer identification schemes. In this paper, the writer identification in Malayalam language is sought for by utilizing feature extraction technique such as Scale Invariant Features Transform (SIFT).The schemes are tested on a test bed of 280 writers and performance evaluated

Es la intuición un método para la toma de decisiones gerencial

El presente trabajo evalúa la toma de decisiones desde el punto de vista descriptivo, exploratorio, dado que no existe un estado del arte al respecto ni estudios que permitan determinar si la toma de decisiones gerencial es intuitiva. Se elaboró una encuesta con 4 variables cada una describiendo un método de toma de decisiones entre los que se operacionalizaron el racional, intuitivo, experiencial y holístico; para determinar el estilo de decisión en cargos gerenciales de la ciudad de Bogotá. Participaron en el estudio 43 voluntarios que en el momento de responder la encuesta se encontraban desempeñando niveles de gerencia general y gerencia de área encontrándose que de los encuestados solo un 35% enfocan su toma de decisiones en una herramienta específica mostrando una preferencia por el método Racional un 19%, seguido del método holístico con un 16% y el Intuitivo un 2%. No se encontró una evidencia significativa en el uso de la intuición como método para la toma de decisiones gerencial aunque quienes eligieron la respuesta Holística sugieren hacer uso de diferentes herramientas y sentimientos para su toma de decisiones.
