Post-crisis market realities in Greece are expected to lead to increased M&A activity in the coming years, little evidence is provided in the academic literature on Greek M&A post-acquisition performance and its driving factors. The overall aim of this thesis is to complement and enhance the existing M&A literature by examining the impact of two post-acquisition actions, of asset divestiture and resource redeployment on the long-term performance of Greek M&A deals over the period 2005-2009. The conceptual framework of this thesis draws on the strategic management perspective. Using the cost efficiencies argument, the thesis examines how cost savings, due to asset divestiture affect the post-acquisition performance of both the target and the acquiring firm. In addition, by drawing on the resource-based view of the firm and the dynamic capabilities perspective, the thesis explores the effects of post-acquisition resource redeployment from acquirers to targets and vice versa, on revenue-enhancing capabilities. The findings revealed that the divestiture of the acquirers’ assets does not reduce costs. In addition, the importance of revenue-based synergies was shown, through the mediating variables of market coverage and innovation capabilities. Finally, acquirer’s resource redeployment has a positive and significant effect on cost savings and the same holds true for the resource redeployment to the target. These results indicate that resource redeployment contributes in achieving higher cost efficiency. The originality of this study is that it tries to obtain new insights on the subject of the post-acquisition performance using arguments from the cost-based and resourcebased synergies, the resource-based view (RBV) of the firm and the dynamic capabilities perspective. In addition, this is a large-scale empirical study conducted in Greece drawing on detailed primary data on a high range of post-acquisition actions followed by the managers of the acquiring companies rather than secondary data.

Some agri-food managers of United States-based companies use strategies to mitigate product-harm crises.The loss of brand and corporate sustainability increases for companies not utilizing mitigating strategies to reduce losses from agri-food product-harm crisis.The purpose of this multiple case study was to explore the strategies managers use to mitigate losses from agri-food product-harm crises. Coombs' situational crisis communication theory served as the conceptual framework for this study. A sample of 3 managers from 3 agri-food companies in the southern United States shared their mitigating strategies to reduce losses from a product-harm crisis. Methodological triangulation assisted in reviewing and analyzing information from semistructured interviews, relevant company documents, and journal notes. The use of alphanumeric coding, discovering, and identifying themes, selecting relevant themes, organizing themes in hierarchical order, and linking themes to the phenomenon under study indicated four main themes supporting the benefits of mitigating strategies to reduce losses from an agri-food product-harm crisis. The main themes included the use of pre-crisis mitigating strategies, mid-crisis mitigating strategies, post-crisis mitigating strategies, and high pressure pasteurization (HPP). Findings from this study indicated that agri-food managers use strategies to mitigate product-harm crises, but the added expense of some mitigating strategies often precludes their use. The study findings may contribute to social change by increasing the awareness of agri-food managers, consumers, and company leadership to use mitigating strategies to reduce the number of illnesses and deaths associated with a product harm crisis.

Background: The field of crisis management has been researched extensively in the last two decades, with a focus on man-made organizational crises in large corporations (Mitroff et al., 2001; Pearson et al., 1993; Weick, 1988). Crises, as phenomena, are very complex events with a low probability of occurrence (Pearson et al., 1998), which subsume multiple layers in their construction causes and manifestation. In the recent years, the number of crises has increased dramatically, with either natural, technological or human causes and each of us can name at least a few dozen examples. Crises are no longer an aberrant, rare, random, or peripheral feature of today’s society. They are built into the very fabric and fiber of modern societies" (Mitroff et al., 2001, p.5). Aim: The purpose of the present research paper is to enhance the understanding of the importance of crisis management for organizations, where the crisis can be triggered by a political unrest situation. Our empirical study will address the issues of how the Gulf Agency Company Egypt team identified, responded and learned from the organizational crisis they were faced with, due to protests against the formal regime of Hosni Mubarak, in the beginning of 2011. Methodology: The goal of our research paper is firstly using existing theory and previous knowledge which will serve as the bricks of our academic construction. Further on, the GAC Egypt case study will be the principal empirical tool that will support and prove or contrast the theoretical roots. In this way, we plan to make use of already existing theory, while in return bringing our own contribution by our results and empirical findings. Completion and results: Our results entail that there are numerous gaps between what the literature on crisis management presents and the organizational procedures in GAC Egypt. In this respect, our findings lead us to notice the absence of an official crisis management plan, minimal perception of credible early signals, weak top management support correlated with a high degree of employee empowerment, as well as the learning outcomes for the organization.

This study aims to reveal what marketing strategies Tunisia has used to alter their place image for the better after the terror attacks that occurred in the country 2015. These terror attacks had a negative effect on Tunisia’s tourism industry; the annual GDP brought by the tourist industry decreased by 19,73%. By using “the multi-step model for altering place image” developed by Eli Avraham and Eran Ketter, this study contains a thematic analysis on qualitative content such as news reports, advertising campaigns and press interviews to uncover what marketing strategies were used by Tunisian official tourism marketers and officials to restore the destinations positive place image and bring back tourist after the terror attacks. The result shows that Tunisia has used strategies from all three categories of strategies; source, audience and message. Furthermore, this study contributes to a better understanding on what marketing strategies a destination could use to alter their place image after gone through a crisis.

This study has aimed to examine how Arjeplog recovered during a five-year period after the Spanish flu using a post-crisis theoretic model and method. Arjeplog is of interest due to the lack of previous studies on the subject despite having the highest mortality rate in Sweden. The post-crisis model present four challenges for Arjeplog after the Spanish flu which this study has examined. The means of handling four challenges was the reconstruction of healthcare, the importance of crisis heroes, the management of orphaned children and the minimization of mental illness. These factors have shown to have both long- and short-term consequences for its citizens and for Arjeplog to transform from a crisis to a post-crisis society. This paper concludes that the reconstruction of healthcare was not only necessary for the future wellbeing of Arjeplog’s citizens but also helped minimize mental illness due to the decreased risk for future widespread pandemics. The study could also conclude that crisis-heroes symbolized the solidarity the citizens displayed during the Spanish flue as well as strengthened existing social ties between families and neighbors. Management of orphaned children due to the Spanish flu was a new issue for Arjeplog where new institutions needed to be established as a result. The children’s and their parents’ perspectives showed the complicated implications regarding both the foster home and the newly established orphanage. The study concluded that the memory of the Spanish flu during the period was very prevalent and showed how crises can affect its victims despite life in general moving on.

La gestion des crises volcaniques constitue un sujet d'étude marginal, tous les domaines de recherche confondus. La complexité des phénomènes volcaniques (aléas multiples, incertitudes des prévisions), l'absence de cadre conceptuel et méthodologique établi pour l'étude des crises, les opportunités réduites de vivre des crises volcaniques, et la focalisation des chercheurs en sciences de la Terre sur l'aléa sont autant de raisons qui expliquent ce manque d'engagement. Cette thèse a pour objectif de combler partiellement ces lacunes en capitalisant des analyses sur les modes de gestion des crises. Elle propose ainsi des RETours d'Expérience sur la gestion de crises éruptives survenues en mai 2006 au Karthala (Grande Comore), et en avril 2007 au Piton de la Fournaise (La Réunion). S'y ajoute un RETEX sur la gestion des lahars consécutifs aux éruptions explosives de 2005 en Grande Comore. Ces cas d'étude reposent sur le vécu direct des crises analysées, puis sur un travail d'enquête auprès des autorités, scientifiques, médias et populations. Ils mettent entre autres en évidence un manque caractérisé de moyens, d'information et de formation de l'ensemble des acteurs sur les deux îles. Les causes profondes des facteurs de dysfonctionnement sont ensuite recherchées. L'analyse révèle le poids des composantes humaines, culturelles, politiques, socioéconomiques et territoriales dans les réponses apportées face aux crises. Enfin, cette thèse propose des outils et des approches pour améliorer la gestion des crises sur les deux îles. / Volcanic crisis management is a marginal study subject, whatever the research field. The complex nature of volcanic phenomena (multiple hazards, uncertainty of forecast), the lack of conceptual and methodological frameworks to study such crises, the reduced opportunities of experiencing volcanic crises, and the fact that Earth scientists focus on the hazard are all the reasons behind this lack of commitment. The objective of this thesis is to make up for some of these shortcomings by building up information on ways to manage crises. It provides post-crisis analysis about the management of the eruptive crisis of May 2006 at Karthala volcano (Grande Comore), and of April 2007 at the Piton de la Fournaise (La Reunion island). It also contains another analysis about the management of lahars subsequent to the explosive eruptions in 2005 in Grande Comore. These study case on personal experiences of analysed crises, then on investigations undertaken with local authorities, scientist, media and population. They highlight, amongst other things, a blatant lack of resources, information and training of all agents on both islands. The cause for such dysfunctioning factors are looked into. The analysis reveals the importance of human, cultural, political, socioeconomic, and territorial components in responding to crises. Finally, this thesis suggests tools and approaches to improve crisis management on both islands.

The world is facing an increase in natural disasters due to climate change, and Sweden is no exception. In the past 10 years Sweden has endured two large forest fires which devastated both land and property and which had huge financial impacts on society. Learning from such disasters is an important task for the crisis management system since learning is vital to be able to both prevent, prepare for, and manage new disasters. By conducting a qualitative in-depth analysis of the post-crisis learning process after the forest fire in 2014, this study aims to examine how actors learn from disasters as well as provide insight into the post-crisis organisational learning process in general. The actions of the Swedish Government and Parliament is evaluated by linking organisational learning to policy change, in such that for learning in the post-crisis management to have happened, the actor needs to have both identified lessons from the disaster, as well as implemented these into policy. In this study a text analysis is conducted on the two inquiries ordered by the Government after the fire to determine the “lessons identified”, and a plethora of government documents is analysed to ascertain whether the lessons identified have been acted upon and implemented into policy. It was found that the inquiries identified many valuable lessons, and that the authorities in most cases had implemented, or tried to implement, the lessons into policy. However, the protracted process of implementation, which led to some measures not being fully implemented until 2021, allowed new fires to occur before the issues were remedied. It is therefore argued that the efficiency of the Swedish Government’s post-crisis learning process should perhaps be questioned.

Introduction : la Terre au Trias inférieur et la reconquête après l’extinction fini-PermienneSitué après la limite entre le Paléozoïque et le Mésozoïque, le Trias inférieur est un intervalle court (~4Ma seulement ; Ovtcharova et al., 2006 ; Galfetti et al., 2007a ; Baresel et al., 2017). Lors de la transition entre le Permien et le Trias (PTB), la configuration tectonique de la Terre était différente, et la plupart des masses continentales étaient rassemblées en un seul super continent, la Pangée, lui-même entouré par un unique océan global, la Panthalassa (e.g., Murphy & Nance, 2008 ; Murphy et al., 2009 ; Stampfli et al., 2013).Lors de cette transition et durant le Trias inférieur, un évènement volcanique majeur, la mise en place de la grande province ignée de Sibérie (e.g., Ivanov et al., 2009, 2013), a conduit à l’émission de grande quantité de gaz à effet de serre (e.g., Galfetti et al., 2007b ; Romano et al., 2013). Ceux-ci ont contribué à l’acidification de la colonne d’eau et à l’augmentation des températures consécutivement à l’injection de CO2 dans l’atmosphère (e.g., Galfetti et al., 2007b ; Sun et al., 2012 ; Romano et al., 2013).Les perturbations environnementales qui en découlèrent ont eu des conséquences sur les milieux de dépôts associés à cette période, mais également sur les écosystèmes. Elles sont supposées avoir contribué à la mise en place de conditions délétères pour les organismes et avoir perduré durant tout le Trias inférieur, restreignant ainsi la rediversification biologique d’après-crise (e.g., Pruss & Bottjer, 2004 ; Fraiser & Bottjer, 2007 ; Bottjer et al., 2008 ; Algeo et al., 2011 ; Meyer et al., 2011 ; Bond & Wignall, 2014 ; Song et al., 2014).La limite PT fut le théâtre de la plus importante et la plus destructrice crise biologique du Phanérozoïque, et fut responsable de la disparition de plus de 90% des espèces marines (Raup, 1979), ou encore de la perte d’environ 50% des familles de tétrapodes continentaux (Benton & Newell, 2014), pour ne citer que ces deux exemples. De nombreux groupes ont été oblitérés durant cette extinction, comme par exemple les groupes caractéristiques du Paléozoïque tels que les coraux tabulés ou encore les trilobites (Sepkoski, 2002). Cependant, si la Vie a failli s’éteindre à l’aube du Mésozoïque, celle-ci a tout de même pu se reconstruire, au prix d’une rediversification communément admise comme lente et difficile dans des conditions environnementales délétères (e.g., Twitchett, 1999 ; Fraiser & Bottjer, 2007 ; Meyer et al., 2011 ; Chen & Benton, 2012). De grands paradigmes sont couramment associés à la rediversification du Trias inférieur (illustrés dans la Figure R.1a) :La présence de taxons « désastre », représentant des organismes opportunistes et généralistes qui auraient proliféré à la suite de la libération de niches écologiques laissées vacantes par les métazoaires disparus (e.g. ; Schubert & Bottjer, 1992, 1995 ; Rodland & Bottjer, 2001 ; He et al., 2007) ;Des faciès dit « anachroniques », composés de récifs exclusivement microbiens tels ceux trouvés dans les dépôts Précambriens (e.g., Schubert & Bottjer, 1992 ; Woods et al., 1999 ; Pruss & Bottjer, 2005 ; Pruss et al., 2005 ; Woods, 2009) ;Un effet « Lilliput », soit un nanisme généralisé des faunes présentes (e.g., Urbanek, 1993 ; Hautmann & Nützel, 2005 ; Payne, 2005 ; Twitchett, 2007 ; Fraiser et al., 2011 ; Metcalfe et al., 2011 ; Song et al., 2011) ;Une anoxie/euxinie généralisée dans le domaine marin, y compris littoral (e.g., Isozaki, 1997 ; Meyer et al., 2011 ; Song et al., 2012 ; Grasby et al., 2013).Fig. R.1 : a) Représentation synthétique des principaux paradigmes communément acceptés pour la rediversification biologique au cours du Trias inférieur. b) Représentation synthétique de ces mêmes paradigmes, révisés selon les données récemment recueillies dans le bassin ouest-américain (d’après Brayard, 2015). Inf. : inférieur ; m. : moyen ; s./sup. : supérieur (...). / In the wake of the Mesozoic, the Early Triassic (~251.95 Ma) corresponds to the aftermath of the most severe mass extinction of the Phanerozoic: the end-Permian crisis, when life was nearly obliterated (e.g., 90% of marine species disappeared). Consequences of this mass extinction are thought to have prevailed for several millions of years, implying a delayed recovery lasting the whole Early Triassic, if not more.Several paradigms have been established and associated to a delayed biotic recovery scenario expected to have resulted from harsh and deleterious paleoenvironments. These paradigms include a global anoxia in the marine realm, a “Lilliput” effect, and the presence of “disaster” taxa and “anachronistic” facies. However, recent works have shown a more complex global scheme for the Early Triassic recovery, and that a reevaluation of these paradigms was needed. Especially, new data from the western USA basin were critical in re-addressing these paradigms.The western USA basin is the result of a long tectono-sedimentary history that started 2 Gyr ago by the amalgamation of different lithospheric terranes forming its basement. A succession of orogenies and quiescence phases led to the formation of several successive basins in the studied area, and traces of this important geodynamical activity are still present today. The Sonoma orogeny occurred about 252 Ma in response to the eastward migration of drifting arcs toward the Laurentian craton. As a result, compressive constrains lead to the obduction of the Golconda Allochthon above the west-Pangea margin in present-day Nevada. Emplacement of this topographic load provoked the lithosphere flexuration beneath present-day Utah and Idaho to form the Sonoma Foreland Basin (SFB) studied in this work.The SFB record an excellent fossil and sedimentary record of the Early Triassic. A relatively high and complex biotic diversity has been observed there leading to describe a rapid and explosive recovery for some groups (e.g., ammonoids) in this basin after the end-Permian crisis. The sedimentary record is also well developed and has been studied extensively for a long time. Overall, these studies notably documented a marked difference between the northern and southern sedimentary succession within the basin, whose origin was poorly understood.This work therefore aims to characterize the various depositional settings in the Early Triassic SFB, as well as their paleogeographical distribution. Their controlling factors are also studied based on an original integrated method using sedimentological, paleontological, geochemical, geodynamical, structural and cartographic analyses. Aside the fossil and sedimentary discrepancy between the northern and the southern parts of the SFB, geochemical analyses provide new insights supporting this N/S dichotomy. This study also questions the validity of the geochemical signal as a tool for global correlation, as it appears to mainly reflect local forcing parameters.The geodynamical framework of the SFB was also investigated along with a numerical modelling of the rheological behavior of the basin. This work distinguishes the northern and southern parts of the basin based on markedly distinct tectonic subsidence rates during the Early Triassic: ~500 m/Myr in the northern part vs ~100m/Myr in the southern part. Origin of this remarkable difference is found in inherited properties of the basin basement itself. Indeed, different ages and therefore, rheological behaviors (i.e., rigidity to deformation and flexuration) of the basement lithospheric terranes act as a major controlling factor over the spatial distribution of the subsidence, and therefore of the sedimentary deposition. The lithosphere heritage is thus of paramount importance in the formation, development and spatio-temporal evolution of the SFB.This work leads to a new paleogeographical representation of the Sonoma Foreland Basin and its multi-parameter controlling factors (...).
