Financial services institutions maintain large amounts of data that include both intellectual property and personally identifiable information for employees and customers. Due to the potential damage to individuals, government regulators hold institutions accountable for ensuring that personal data are protected and require reporting of data security breaches. No company wants a data breach, but finding a security incident or breach early in the attack cycle may decrease the damage or data loss a company experiences. In multiple high profile data breaches reported in major news stories over the past few years, there is a pattern of the adversary being inside the company’s network for months, and often law enforcement is the first to inform the company of the breach. The problem that was investigated in this case study was whether new information technology (IT) utilized by Fortune 500 financial services companies led to the changes in data security incidents and breaches. The goal of this dissertation is to gain a deeper understanding on how IT can increase awareness of a security incident or breach, and can also decrease security incidents and breaches. This dissertation also explores how threat information sharing increases awareness and decreases information security incidents and breaches. The objective of the study was to understand how changes in IT can influence an increase or decrease in data security breaches. This investigation was a case study of nine Fortune 500 financial services companies to understand what types of IT increase or decrease detection of security incidents and breaches. An increase in detecting and stopping a security incident or breach may have positive effects on the security of an enterprise. The longer a hacker has access to IT systems, the more entrenched they become and the more time the hacker has to locate data with high value. Time is of the essence to detect a compromise and react. The results of the case study showed that Fortune 500 companies utilized new IT that allowed them to improve their visibility of security incidents and breaches from months and years to hours and days.

中國是一個興起中的強權，中國領導人的世界觀與國際戰略，將深刻影響到未來世界秩序的形成，且影響力有增無減；尤其，在現代化的過程中，中國大陸突破以市場經濟與代議民主為核心的制式模式，試圖開創獨特的政經體制，且自改革開放以來，經濟高度穩定成長，使其整體國力不斷提昇，綜合國力讓人不能忽視。 其中中共外交政策研究不僅是研究中國大陸問題的一項重要議題，也是為研究國際關係學者無法加以忽略的環節。有關中國大陸「決策過程」之研究，可以使得我們更豐富地瞭解中國大陸所面臨之各種環境因素，決策者所重視的政策問題以及其解決方式，進而獲知中國大陸政治系統之結構特徵及運作方式。 當中以大國關係的說法充份反映了中國外交政策前提的演化，也同時涉及了中國在世界上的自我定位，甚至還對維持其國內秩序的各種制度安排，提供了新的視野與期盼。「九一一事件」使東亞大國間關係發生若干變化，其主要特徵為：中美關係在美國的反恐戰爭後獲得改善，但結構性與戰略緊張的本質尚未發生根本改變。 在決策方面，就理論上說來，中共其實也要求決策的科學化和民主化，強調一切決策應該以建設具有中國特色的社會主義為總目標，要堅持以人民為主體的思想，加強決策制度的建設，希望能在把握國情的基礎上，堅持決策的連續性與創造性，以實現決策程序的制度化。 中共當前的決策重點似乎並不在於事先制定一個完美、理想的決策方案，而是要利用已有的資訊，迅速作出盡量準確的決策，然後再透過決策程序中的有關機制再逐步加以改善、調整。換句話說，中共的某些決策者認為，凡事要冒點風險，不能為了追求完美而錯過了時機，有限的錯誤可以透過總結經驗及反饋調整來加以改善。因此，中共是把蒐集資料、制定方案、確定目標的過程適度的壓縮，其決策並未一味強求必須是「最佳」的決策，而是要求相對「較佳」的選擇。中共所說「摸著石頭過河」差可反映此一思維。 本文希望藉由江澤民時期對美國安全關係的檢驗分析，來探討中共外交決策模式，研究方向是由江澤民時期中共與美國安全關係的演變，此期間中共外交決策機構與運作，參與外交決策的黨政組織架構，瞭解決策過程中的黨政權力運作，以外交決策模型的檢驗，來探討理性行為者模式。 / While China is a rising superpower, the global view and international strategy of its rulers will greatly influence the order of the future world. The influence will keep increasing ; especially, in the process of its modernization, China ﹙Mainland China﹚ broke the mode of western market economy and democracy and is attempting to create unique political system and economical system. Since it opened up to the world, Chinas’ecomomy has kept growing steabily and enhanced its national power. Its overall national strength has been so powerful that no other countries in the world can ignore it. China's foreign policy is one of the important issues studied by the experts in Chinese problems. Such issue is also highly valued by the expects in international relations. The study on the process of China's decision-making enables us to fully understand the situations that China has been faced with, and the problem the policy maker concentrate and the solutions to them. Furthermore, the study also enables us to realize the features of its political structures and the ways it operates. China's so-called “the relation among the superpowers”not only reflects the evolution of recent Beijing foreign policy but also relates to its identity in the world. The theory also provides new perspective on maintaining its domestic order. 911Incident changed the relation among China,U.S.A. and Japan. Among the changes, the main feature is that the relationship between China and the US improved after the anti- terrorism war launched by U.S,A. However ,the improvement does't basic change the structure of their relations and tension caused by each other's international strategy still exist. In terms of its decision-making , China demans to make all political decisions scientically and through democratical process . they emphasize that Chinese socialism is the only goal of all constructions, stick to the ideology of people-oriented, and enorce their polical decisions. To systematize of the proceduce of making political decision, they expect to persist in the continuity and creativity of their political decisions on the basic of their national conditions. The top priority of China is not to establish a perfect and ideal system of making polical decision in advance. Instead , they utilize the information they have owned to make a more accurate decision rapidly and then gradually improve and adjust it in the procedure. In other words, China's decision makers think that everything take risks , that it is unwise to miss a good opportunity for the perfection and that some mistakes can be improved through experience and adjustment. Therefore, China appropriately shortens the procedures of collecting information, making scheme, and confiming goals. They don't expect the best decision but a better one. A Chinese saying, to wade across the stream by feeding the way, reflects the thinking mentioned above. The research studies the framework of China's foreign policy by analyzing the security relations to U.S.A. in Jiang Zemin's term. To understand the procedure of how Chinese Communists operate their polical power, I focus on the development of China and U.S.A.'s security relations in Jiang Zemin's term and the organizations which took charge of China's foreign policy and their operation.

Les recherches en sécurité routière suscitent largement l'intérêt des chercheurs. Indépendamment des techniques de modélisation, un facteur important d'imprécision -qui caractérise les études dans ce domaine- concerne le niveau d'agrégation des données. Aujourd'hui, la plupart des autoroutes sont équipées de systèmes permanents de surveillance qui fournissent des données désagrégées. Dans ce contexte, l'objectif de la thèse est d'exploiter les données trafic recueillies en temps réel au moment des accidents, afin d'élargir le champ des travaux précédents et de mettre en évidence un potentiel d'applications innovantes. À cette fin, nous examinons les effets du trafic sur le type d'accident ainsi que sur la gravité subie par les occupants des véhicules, tout en tenant compte des facteurs environnementaux et géométriques. Des modèles Probit sont appliqués aux données de trafic et d'accidents enregistrés pendant quatre années sur le tronc commun aux autoroutes A4 et A86 en Ile-de-France. Les résultats empiriques indiquent que le type d'accident peut être presque exclusivement défini par les conditions de trafic prévalant peu avant son occurrence. En outre, l'augmentation du débit s'avère exercer un effet constamment positif sur la gravité, alors que la vitesse exerce un effet différentiel sur la gravité en fonction des conditions d'écoulement. Nous établissons ensuite un cadre conceptuel pour des applications de gestion des incidents qui s'appuie sur les données trafic recueillies en temps réel. Nous utilisons les résultats de la thèse afin d'explorer des implications qui ont trait à la propension et à la détection des incidents, ainsi qu'à l'amélioration de leur gestion / Research on road safety has been of great interest to engineers and planners for decades. Regardless of modeling techniques, a serious factor of inaccuracy - in most past studies - has been data aggregation. Nowadays, most freeways are equipped with continuous surveillance systems making disaggregate traffic data readily available ; these have been used in few studies. In this context, the main objective of this dissertation is to capitalize highway traffic data collected on a real-time basis at the moment of accident occurrence in order to expand previous road safety work and to highlight potential further applications. To this end, we first examine the effects of various traffic parameters on type of road crash as well as on the injury level sustained by vehicle occupants involved in accidents, while controlling for environmental and geometric factors. Probit models are specified on 4-years of data from the A4-A86 highway section in the Ile-de -France region, France. Empirical findings indicate that crash type can almost exclusively be defined by the prevailing traffic conditions shortly before its occurrence. Increased traffic volume is found to have a consistently positive effect on severity, while speed has a differential effect on severity depending on flow conditions. We then establish a conceptual framework for incident management applications using real-time traffic data on urban freeways. We use dissertation previous findings to explore potential implications towards incident propensity detection and enhanced management

Von Fahrzeugen des Öffentlichen Verkehrs sind deren Positionen bekannt, wenn sie informationstechnisch in ein Betriebsleitsystem eingebunden sind. Über die auf dem Streckenband zwischen Meldepunkten zurückgelegte Wegstecke und die jeweils dafür benötigte Zeit kann auf die mittlere Geschwindigkeit geschlossen werden. Aus dieser wiederum kann eine Verkehrslageaussage abgeleitet werden. In wie weit diese für den Gesamtverkehrsstrom gültig, belastbar und richtlinienkonform ist, welche Randbedingungen für eine Auswertung einzuhalten sind, welche Verfahren sich zur Aufbereitung anbieten und welche Nutzungsszenarien unterstützt werden, wird aufgezeigt.

Le présent mémoire s’intéresse aux interventions policières en contexte de crise. Il s’attarde plus particulièrement à l’usage de la force par les structures d’intervention spécialisée. L’intérêt de cette étude découle principalement du manque de connaissances empiriques sur le sujet. L’objectif général de cette étude est de comprendre les éléments qui peuvent expliquer le recours à la force par les structures d’intervention spécialisées et de vérifier si ces facteurs varient selon le type de menace auquel font face les policiers. Nous nous sommes intéressés à 438 événements de crise suicidaire, de barricade et de prise d’otage qui se sont déroulés au Québec, de 1990 à 2011, et durant lesquels est intervenu le groupe tactique d’intervention (GTI) de la Sûreté du Québec (SQ). Pour une meilleure compréhension de cette problématique, il sera en premier lieu question de comparer, selon leur niveau de risque, les personnes présentant une menace uniquement pour elles-mêmes avec celles présentant une menace pour autrui et les personnes qui présentent une menace tant pour elles-mêmes que pour autrui. En second lieu, malgré le fait que près de 90 % des situations de crise se terminent par une reddition pacifique, il est pertinent de connaître les facteurs qui expliquent l’usage de la force de la part des policiers et de voir si ces facteurs varient selon le niveau de risque de l’individu. Des analyses descriptives ont permis d’établir que les situations où l’individu en crise présente uniquement une menace pour lui-même diffèrent des autres groupes sur la base de certaines variables. Cet individu est davantage jugé comme suicidaire et il possède plus souvent des antécédents psychiatriques. L’élément déclencheur est souvent associé aux problèmes conjugaux, ce qui coïncide avec le fait que c’est souvent la conjointe ou l’ex-conjointe qui appelle les autorités. Des analyses bivariées n’ont pas illustré de profils distincts selon la problématique de la crise. Or, certains facteurs se démarquent des autres de manière générale pour l’ensemble de l’échantillon et les différents groupes. La possession d’une arme par l’individu, le degré d’intoxication, la présence d’antécédents psychiatriques, la durée du premier contact avec les policiers et la qualité de la négociation sont effectivement des facteurs qui semblent influencer à un certain point les opérations. Les analyses de régression logistique indiquent que les policiers interviennent davantage lorsqu’il n’y aucun contact n’est établi avec l’individu. Nous observons également que ces derniers restent davantage en retrait lorsque l’individu, présentant une menace pour lui-même, est en possession d’une arme à feu. D’autre part, il semble que les policiers réagissent plus souvent auprès des individus présentant une menace pour autrui lorsque la négociation est jugée non satisfaisante. Nous pouvons en conclure qu’ils semblent davantage s’attarder à des facteurs précis qu’au type de menace, ce qui rejoint un certain segment de la littérature à ce sujet. / This thesis argues that police intervention in a crisis context focuses specifically on the use of force by specialized intervention teams. The interest in this study pinpoints mainly the lack of empirical data on the subject. Therefore, the main objective is to understand how to explain the use of force by specialized intervention teams and to verify if these factors vary according to the type of threat police encounter in a particular situation. We studied 438 suicidal crises, barricade and hostage-taking situations that occurred in Quebec from 1990 to 2011, supervised by the Sûreté du Québec’s tactical intervention group (GTI). To begin with, for a better understanding of this issue, we will compare individuals according to the level of risk each one represents, i.e. those presenting a threat only to themselves, those presenting a danger to others and those who pose a threat to themselves and others. Secondly, despite the fact that almost 90 % of critical incidents end in a non-violent conclusion, it is interesting to understand the risk factors involved that explain the use of force by the police and to realize that these factors vary according to the level of risk exhibited by the individual in crisis. Descriptive analyses were used to demonstrate that the situation where the individual in crisis was a threat only to himself differed from other instances based on different variables. Overall, the general level of risk for this type of intervention is less significant since the danger appears to be directed specifically to the individual in crisis, taking into consideration that negotiation has been successful, also, considering the subject has limited or no access to firearms, and considering weapons are not frequently used. Bivariate analysis relating the different characteristics of the individual, the situation and negotiation with the use of force by the police, suggest that certain variables can have different effects depending on the type of threat facing authorities. For example, a history of psychiatric issues would increase the risk of police intervention among those who pose a non-aggressive threat to himself, but would decrease the probability of police intervention for those individuals who present a double threat, i.e. to themselves and others. Consequently, bivariate analyses suggest that certain variables, such as the possession of a weapon by an individual, the degree of intoxication, the presence of known psychiatric issues, the duration of the first contact with the police and the quality of the negotiation, could influence the use of force by police officers. Logistic regression analyses indicate that few of these variables resist multivariate analyses. These findings suggest that police intervene more so when there is no contact established with the individual, and this, regardless of the type of threat manifested. On the contrary, a non-satisfactory negotiation would encourage police to use force in cases where the individual presents no threat to himself. In sum, these multivariate analyses show that the police are less influenced by the type of threat, rather preferring negotiation as long as possible.

Les problématiques de sécurité, ainsi que le coût de moins en moins élevé des caméras numériques, amènent aujourd'hui à un développement rapide des systèmes de vidéosurveillance. Devant le nombre croissant de caméras et l'impossibilité de placer un opérateur humain devant chacune d'elles, il est nécessaire de mettre en oeuvre des outils d'analyse capables d'identifier des évènements spécifiques. Le travail présenté dans cette thèse s'inscrit dans le cadre d'une collaboration entre le Laboratoire Bordelais de Recherche en Informatique (LaBRI) et la société Adacis. L'objectif consiste à concevoir un système complet de vidéo-surveillance destiné à l'analyse automatique de scènes autoroutières et la détection d'incidents. Le système doit être autonome, le moins supervisé possible et doit fournir une détection en temps réel d'un évènement.Pour parvenir à cet objectif, l'approche utilisée se décompose en plusieurs étapes. Une étape d'analyse de bas-niveau, telle que l'estimation et la détection des régions en mouvement, une identification des caractéristiques d'un niveau sémantique plus élevé, telles que l'extraction des objets et la trajectoire des objets, et l'identification d'évènements ou de comportements particuliers, tel que le non respect des règles de sécurité. Les techniques employées s'appuient sur des modèles statistiques permettant de prendre en compte les incertitudes sur les mesures et observations (bruits d'acquisition, données manquantes, ...).Ainsi, la détection des régions en mouvement s'effectue au travers la modélisation de la couleur de l'arrière-plan. Le modèle statistique utilisé est un modèle de mélange de lois, permettant de caractériser la multi-modalité des valeurs prises par les pixels. L'estimation du flot optique, de la différence de gradient et la détection d'ombres et de reflets sont employées pour confirmer ou infirmer le résultat de la segmentation.L'étape de suivi repose sur un filtrage prédictif basé sur un modèle de mouvement à vitesse constante. Le cas particulier du filtrage de Kalman (filtrage tout gaussien) est employé, permettant de fournir une estimation a priori de la position des objets en se basant sur le modèle de mouvement prédéfini.L'étape d'analyse de comportement est constituée de deux approches : la première consiste à exploiter les informations obtenues dans les étapes précédentes de l'analyse. Autrement dit, il s'agit d'extraire et d'analyser chaque objet afin d'en étudier son comportement. La seconde étape consiste à détecter les évènements à travers une coupe du volume 2d+t de la vidéo. Les cartes spatio-temporelles obtenues sont utilisées pour estimer les statistiques du trafic, ainsi que pour détecter des évènements telles que l'arrêt des véhicules.Pour aider à la segmentation et au suivi des objets, un modèle de la structure de la scène et de ses caractéristiques est proposé. Ce modèle est construit à l'aide d'une étape d'apprentissage durant laquelle aucune intervention de l'utilisateur n'est requise. La construction du modèle s'effectue à travers l'analyse d'une séquence d'entraînement durant laquelle les contours de l'arrière-plan et les trajectoires typiques des véhicules sont estimés. Ces informations sont ensuite combinées pour fournit une estimation du point de fuite, les délimitations des voies de circulation et une approximation des lignes de profondeur dans l'image. En parallèle, un modèle statistique du sens de direction du trafic est proposé. La modélisation de données orientées nécessite l'utilisation de lois de distributions particulières, due à la nature périodique de la donnée. Un mélange de lois de type von-Mises est utilisée pour caractériser le sens de direction du trafic. / Automatic traffic monitoring plays an important role in traffic surveillance. Video cameras are relatively inexpensive surveillance tools, but necessitate robust, efficient and automated video analysis algorithms. The loss of information caused by the formation of images under perspective projection made the automatic task of detection and tracking vehicles a very challenging problem, but essential to extract a semantic interpretation of vehicles behaviors. The work proposed in this thesis comes from a collaboration between the LaBRI (Laboratoire Bordelais de Recherche en Informatique) and the company Adacis. The aim is to elaborate a complete video-surveillance system designed for automatic incident detection.To reach this objective, traffic scene analysis proceeds from low-level processing to high-level descriptions of the traffic, which can be in a wide variety of type: vehicles entering or exiting the scene, vehicles collisions, vehicles' speed that are too fast or too low, stopped vehicles or objects obstructing part of the road... A large number of road traffic monitoring systems are based on background subtraction techniques to segment the regions of interest of the image. Resulted regions are then tracked and trajectories are used to extract a semantic interpretation of the vehicles behaviors.The motion detection is based on a statistical model of background color. The model used is a mixture model of probabilistic laws, which allows to characterize multimodal distributions for each pixel. Estimation of optical flow, a gradient difference estimation and shadow and highlight detection are used to confirm or invalidate the segmentation results.The tracking process is based on a predictive filter using a motion model with constant velocity. A simple Kalman filter is employed, which allow to predict state of objets based on a \textit{a priori} information from the motion model.The behavior analysis step contains two approaches : the first one consists in exploiting information from low-level and mid-level analysis. Objects and their trajectories are analysed and used to extract abnormal behavior. The second approach consists in analysing a spatio-temporal slice in the 3D video volume. The extracted maps are used to estimate statistics about traffic and are used to detect abnormal behavior such as stopped vehicules or wrong way drivers.In order to help the segmentaion and the tracking processes, a structure model of the scene is proposed. This model is constructed using an unsupervised learning step. During this learning step, gradient information from the background image and typical trajectories of vehicles are estimated. The results are combined to estimate the vanishing point of the scene, the lanes boundaries and a rough depth estimation is performed. In parallel, a statistical model of the trafic flow direction is proposed. To deal with periodic data, a von-Mises mixture model is used to characterize the traffic flow direction.

9 The main focus of the thesis is on the street work with migrants and the dilemma of help and control that arises in it. An integral part of this was the presentation of available literature dealing with this topic and its analysis. The theoretical part defines the target group, migrants in the Czech Republic and integration and migration policy in the Czech Republic. It also deals with street work, the legislative framework of street work, the personality of the street worker and the specifics of street work with migrants and also social work with migrants is described. Attention is paid to the dilemmas in social work, their origin with an emphasis on the help and control dilemma and ways of coping. The research part is devoted to the description of own qualitative research, which was carried out by the method of semi-structured interviews with street workers focusing on working with migrants by using the technique of critical incident. The main aim of the research was to find out in which cases the street workers encounter the dilemma of help and control and how to deal with it. Data were analyzed by using a portion of grounded theory. The presented research results point to situations in which street workers who work with migrants experience a dilemma of help and control. For example, there are...

Nesta pesquisa, o suicídio foi considerado, pelas rupturas que engendra, um evento crítico (DAS, 1997; MISSE et al., 2012) de grande impacto na vida dos familiares e da comunidade em geral que reflete, de certo modo, um processo social mais amplo. A pesquisa teve como objetivo compreender o processo social em que os suicídios dos idosos ocorreram e seus efeitos na vida dos sobreviventes. O método utilizado privilegiou uma abordagem qualitativa dos dados. Foram realizadas 15 autópsias psicossociais de idosos (10 homens e cinco mulheres) que cometeram suicídio e sete entrevistas semiestruturadas. Participaram da pesquisa, ao todo, 22 familiares (ou sobreviventes) de idosos que se suicidaram. A análise textual discursiva (MORAES; GALIAZZI, 2007) permitiu a emergência de categorias que foram reorganizadas a partir do conceito de homologia (WILLIAMS, 1979) e da noção de evento crítico. Os resultados mostram: a) a complexa rede de fatores que interagem e se sobrepõem na produção do evento crítico que é o suicídio de idosos, entre os quais estão: a baixa escolaridade, a influência da colonização alemã, a importância do trabalho na vida dos agricultores, a penalização do corpo pelas condições de trabalho no cultivo do fumo, a ausência de lazer, a desvalorização do idoso, a perda de sentido da vida com a interrupção do trabalho, o medo de ser um estorvo para os familiares, a perda da saúde e do vigor físico, a ausência da fé, o histórico de agressividade, a perda financeira; b) efeitos na vida dos sobreviventes: o adoecimento psíquico (ansiedade, insônia, dificuldade de retomar a vida), as práticas religiosas para auxiliar o duplo da pessoa que morreu no pós-vida, o abandono da casa ou tentativa de apagar, no âmbito da materialidade, os vestígios dessa morte que tem mana; c) a necessidade de Programas de Prevenção ao suicídio e a circulação da palavra sobre o tema. / Elderly suicide is a social phenomenon which has become a major public health problem, especially in Rio Grande do Sul. In this research, due to the disruptions caused by suicide, it has been considered a critical incident (DAS, 1997; MISSE et al., 2012) of great impact in the lives of the family members and the community in general which it reflects, in a certain way, a broader social process. The goal of this research was to understand the social process in which the suicide of elderly people took place and the effects of these critical incidents on the lives of the survivors. The research method focused on a qualitative approach to data. We performed 15 psychosocial autopsies of elderly people (10 men and five women) who committed suicide, and seven semi-structured interviews. Altogether, twenty-two family members (or survivors) took part in this research. The discursive textual analysis (MORAES; GALIAZZI, 2007) allowed the emergence of some categories which were reorganized based on the concept of homology (WILLIAMS, 1979) and the notion of critical incident. The results showed: a) the complex network of factors which interact and overlap, leading up to this critical incident (elderly suicide), some of them being: a low level of education, the influence from German colonization, the importance of work in the lives of farmers, the body injuries caused by the working conditions of tobacco cultivation, the lack of leisure time, the devaluation of the elderly, the loss of meaning in life due to interruption of work, the fear of being a hindrance for the family, the health loss and reduced physical energy, the lack of faith, a history of aggressiveness, a financial loss; b) the effects on the lives of suicide survivors: mental disorders (anxiety, insomnia, difficulty to resume normal life), religious practices to help the deceased's double in their afterlives, house abandonment or attempt to remove, materially, traces of the death, which has mana; c) the necessity of creating suicide Prevention Programs and spreading the word on the subject.

I forskningen har organisatoriskt lärande uppmärksammats, men inte institutionaliserats. Det organisatoriska lärandet påverkas i stor grad av nyckelpersoner vilket ledare och mellanchefer är. Organisatoriskt lärande styrs av det individuella lärandet vilket därför har en stor betydelse i sammanhanget. Ansvaret för det individuella lärandet läggs oftast på organisationens ledare och för ledares individuella lärande är reflektion och erfarenhet en avgörande faktor. Därför var studiens syfte att bidra till forskningen genom att undersöka hur kritiska situationer påverkat ledares lärande och bidragit till det individuella och organisatoriska lärandet. Syftet har studerats utifrån hur ledares reflektion görs och hur reflektionen påverkat ledares ledarskapsstil och orientering. För att studera detta användes vår egen tolkning av kritiska situationer tekniken. Studiens teoretiska referensram baserades därför på individuellt och organisatoriskt lärande, ledarskapsstilar, samt reflektion.Tillvägagångssättet som valdes var att intervjua ledare på mellanchefsnivå, halvstrukturerade intervjuer genomfördes baserat på kritiska situationer tekniken där olika kritiska scenarion diskuterades. I studien genomfördes även en enkät med samtliga intervjuade ledare där de fick uppskatta sin upplevda grad av orientering. Studiens konklusion är att fokus inte bör läggas på kombinerade ledarskapsstilar utan att vikten bör läggas på graden av orientering inom uppgift, relation och förändring. I studien kunde även ett samband identifieras som förklarar vad som krävs av ledare för att uppnå och bidra till organisatoriskt lärande. / Program: Civilekonomprogrammet
