Les données évaluant la prise en compte par les dirigeants de collectivités territoriales de la Sécurité de leurs Systèmes d’Information (SSI) sont rares en général et quasiment inexistantes en France. Dans le même temps, cette sécurisation constitue un impératif stratégique majeur qui dépasse le simple cadre local au regard de l’augmentation constante des cyberattaques contre des collectivités – y compris de taille modeste – depuis le début de la crise sanitaire. Cet article s’intéresse en partie à ce paradoxe et tente de combler ce gap. Les fondements théoriques de cette recherche reposent sur trois piliers, les travaux liés à l’adoption et à l’appropriation des outils numériques en mode TOE de Tornatzky et Fleischer (1990), les travaux sur les risques numériques en organisation publique de Norris et al. (2019) et les travaux liés à la prévention des cyberattaques de Février (2020). Il est empiriquement fondé sur les données de l’unique enquête spécifiquement réalisée à ce jour en cybersécurité auprès de 67 dirigeants de collectivités de moins de 3 500 habitants avec un traitement statistique successivement descriptif puis par classification hiérarchique. L’article pose la question du « pourquoi » de cette vulnérabilité en décryptant les freins retardant le déploiement d’une véritable politique de sécurisation des SI des collectivités territoriales. L’analyse menée tend à mettre en évidence certaines lacunes en matière de prise de conscience de la réalité des risques numériques par les décideurs territoriaux et propose une typologie des profils de dirigeants de collectivités relativement au management des risques numériques. L’objectif poursuivi est de contribuer à l’opérationnalisation par les pouvoirs publics d’une démarche volontariste de sécurisation structurelle des SI territoriaux ainsi que des données à caractère personnel des citoyens.

Background:Considerable epidemiological variations in prevalence of Behçet’s disease (BD) have been reported. These disparities may either reflect geographical differences, methodological artifacts, changes over time or random fluctuations. In Spain, published BD’s epidemiological studies are scarce.Objectives:To study epidemiological and clinical domains of BD in a well-defined population of Northern Spain, as well as, to compare results with other regions.Methods:We included all consecutive 111 patients, diagnosed of definitive or possible BD by expert rheumatologists between 1980 and 2019. Two Classification criteria were applied: a) International Study Group (ISG) for BD(Lancet. 1990; 335:1078-80), and b) International Criteria for BD (ICBD)(J Eur Acad Dermatol Venereol. 2014; 28:338-47). In addition, a literature review of Medline publications was carried out.Results:In our study, prevalence was higher than in most European populations regardless of the diagnostic criteria applied. Incidence was low (expert opinion: 0.021, ICBD: 0.016, ISG: 0.012). Mean age at onset (36.8±13.2) and gender distribution (55.9% females) were similar to other countries. Pathergy test was performed in 9% of patients giving low results (25.2%). Clinical domains’ frequency was in line with other regions except vascular and gastrointestinal involvement, which were lower. (TABLE)Conclusion:BD’s prevalence in Northern Spain is higher than in most European populations. These differences likely reflect a combination of true geographic variation, methodological artifacts as well as the easy access to Public Health System and its efficiency. In contrast, clinical phenotypes are similar to other regions.TABLEDiagnostic criteria and study periodn cases / population sizeMean age at onset and sex (%females)Prevalence (over 100000) / incidenceOral / genital ulcers (%)Skin lessions/ pathergy test (%)Ocular involvement (%)Joint involvement (%)Neurobehcet/ Vascular/ Gastrointestinal involvement (%)Herrero, A et al.

Background:Behçet disease (BD) is a systemic and potentially severe disease. Its incidence varies widely worldwide. In Spain, published BD’s epidemiological studies are scarce.Objectives:In a well-defined Northern Spanish population-based cohort, the aim of this study was a) to estimate epidemiological variations, b) clinical domains and c) to compare our results with other regions.Methods:Study of unselected all consecutive patients diagnosed with definitive or possible BD by expert rheumatologists between 1980 and 2020 in our health region. Two classification criteria were applied: a) International Study Group (ISG) for BD [1], and b) International Criteria for BD (ICBD) [2]. In addition, a literature review of Medline publications was carried out.Results:In this study, from a total of 120 patients diagnosed with BD by expert opinion (58 women/62 men), 96 met ICBD and 59 ISG criteria. Mean age of the cohort at diagnosis was 37.6±13.8 years similar to other countries, as well as sex distribution.Prevalence was higher than in most European populations regardless the diagnostic criteria applied: expert opinion (20.6), ICBD (16.5) or ISG (10.1) (TABLE 1). Incidence was lower (expert opinion: 0.022, ICBD: 0.018, ISG: 0.011). Clinical domains’ frequency was in line with other regions except vascular and gastrointestinal involvement, which were lower.TABLE 1.Diagnostic criteria and study periodn cases / population sizeMean age at onset and sex (%female)Prevalence (over 100000) / incidenceOral / genital ulcers (%)Skin lessions/ pathergy test (%)Ocular involve ment (%)Joint involve ment (%)Neurobehcet/ Vascular/ Gastrointestinalinvolvement (%)Sánchez.

Optimised project delivery methods forsocial housing energy renovations European Social Housing Organisations (SHOs) are currently facing challenging times. The ageing of their housing stock and the economic crisis, which has affected both their finances and the finances of their tenants, are testing their capacity to stick to their aim of providing decent and affordable housing. Housing renovation projects offer the possibility of upgrading the health and comfort levels of their old housing stock to current standards and improve energy efficiency, and this solution also addresses the fuel poverty problems suffered by some tenants. Unfortunately, the limited financial capacity of SHOs is hampering the scale of housing renovation projects and the energy savings achieved. At the same time, the renovation of the existing housing stock is seen as one of the most promising alternative routes to achieving the ambitious CO2 emissions reduction targets set by European authorities – namely, to reduce EU CO2 emissions to 20% below their 1990 levels by 2020. The synergy between European targets and the aims of SHOs has been addressed by the energy policies of the member states, which focus on the potential energy savings achievable by renovating social housing. In fact, the European initiatives have prioritised energy savings in social housing renovations to such an extent that these are referred to as ‘energy renovations’. Energy renovation is therefore a renovation project with higher energy savings target than a regular renovation project. In total, European SHOs own 21.5 million dwellings representing around 9.4% of the total housing stock. Each SHO owns a large number of dwellings, which means there are fewer people to convince of the need to make energy savings through building renovations, maximising the potentially high impact of decisions. Moreover, SHOs are responsible for maintaining and upgrading their properties in order to continue renting them. As such, SHOs are used to dealing with renovations on a professional basis. The limited financial capacity of SHOs to realise energy renovations magnifies the importance of improving process performance in order to get the best possible outcomes. In the last 30 years numerous authors have addressed the need to improve the performance of traditional construction processes via alternative project delivery methods. However, very little is known about the specifics of renovations processes for social housing, the feasibility of applying innovative construction management methods and the consequences for the process, for the role of all the actors involved and for the results of the projects. The aim of this study is to provide an insight into the project delivery methods available for SHOs when they are undertaking energy renovation projects and to evaluate how these methods could facilitate the achievement of a higher process performance. The main research question is: How can Social Housing Organisations improve the performance of energy renovation processes using more integrated project delivery methods? The idea of a PhD thesis about social housing renovation processes originated from the participation of TU Delft as research partner in the Intelligent Energy Europe project SHELTER1 which was carried out between 2010 and 2013. The aim of the SHELTER project was to promote and facilitate the use of new models of cooperation, inspired by integrated design, for the energy renovation of social housing. The SHELTER project was a joint effort between six social housing organisations (Arte Genova, Italy; Black Country Housing Group, United Kingdom; Bulgarian Housing Association, Bulgaria; Dynacité, France; Logirep, France and Société Wallonne du Logement, Belgium), three European professional federations based in Brussels (Architects Council of Europe, Cecodhas Housing Europe and European Builders Confederation) and one research partner (Delft University of Technology). Research methods This thesis is composed of five studies. The first study is based on a literature review. The second study is based on five case studies from four countries (Belgium, Italy, France and United Kingdom), a questionnaire completed by 36 SHOs from eight countries and 14 interviews with experts from ten countries. The third is based on two French case studies and the fourth and fifth are based on 8 and 13 Dutch case studies respectively. Construction projects in housing involve a high number of professionals and take place over a long period of time. External factors, such as the economic and political situation or changes in construction or procurement regulations, can have a considerable influence on the construction process. Moreover, the specific characteristics of the construction sector of every country can also shape the process. In consequence, there are many interrelated variables that can have an influence on the dynamics of the process and on the outputs achieved. Research that seeks to understand the causes of changes in this process need to dig deeper into the internal and external characteristics of the process, which makes case study research the most appropriate research method for this type of study. The cases in each of the studies have been selected because innovative project management methods aiming for better collaboration between the participating actors were applied and because it was possible to gather high-quality data concerning these projects. The data were gathered mainly through interviews but other methods were also used: a questionnaire, observations and an analysis of tender documents. A protocol based on the recommendations of case study research literature was applied to assure the scientific validity of the data collected through the interviews. The case studies were complemented with a wide-ranging literature review covering scientific publications on project management in construction, mainly from the UK, the US, Australia, the Netherlands, Hong Kong and Finland. Reports from Intelligent Energy Europe projects were also reviewed, as well as legal texts relating to the tender options open to European social housing organisations. Construction management methods How to improve the performance of construction processes has long been and is still one of the key issues of the construction industry sector, social housing included. The performance of construction processes has been addressed from a range of perspectives in the construction management literature and diverse project management methods have been proposed. These methods are interrelated and in constant evolution. Moreover, different terminology is used to describe similar methods, which makes it difficult to obtain a clear picture. To simplify, three main perspectives or methods to improve the process integration and actors collaboration can be identified: the multi-project: supply chain integration; the single-project: integrated project delivery methods; and collaboration: partnering. Supply chain integration looks at the performance of the construction process from a multi-project perspective, relating the construction process to an industrial process. The project delivery method takes a single-project perspective into account because it is based on the premise that the complexity and singularity of any construction project will make it unique. Finally, partnering is focused on the characteristics of collaboration between the actors involved in the construction process. The singularity of renovation projects and the limitations of public procurement make the single project perspective the most feasible strategy for improving the process performance of social housing renovation projects. As such, the analysis of the project delivery methods is the most suitable method for improving the performance of renovation processes. The literature review shows that the more integrated project delivery methods are particularly indicated for construction projects with a high commitment to sustainability in general and for energy performance in particular. The literature review also reveals that the key factor in the process efficiency of all project delivery methods is collaboration between the actors involved in the project. Partnering methods can have a substantial positive influence on process performance. The study of the legal limitations imposed by the currently applicable public procurement Directive 2004/18/EC shows that even though a limited amount of tender options are available, is it possible to tender projects that apply integrated project delivery methods using the competitive dialogue procedure. Moreover, the recently approved but not yet enacted public procurement Directive 2014/24/ EU facilitates even further the use of competitive dialogue tenders for social housing energy renovations. Project delivery methods in European social housing energy renovations This study is based on five case studies, 36 questionnaires and 14 expert interviews, and identified four main project delivery methods for the energy renovation of social housing, namely: Step-by-Step (SBS) Design-Bid-Build (DBB) Design-Build (DB) Design-Build-Maintain (DBM). SBS can be considered a major renovation when the replacement of a series of building components eventually produces the same final result as a renovation project. In order to optimise the service lives of building components, an SHO might choose to split a major renovation project into a series of minor renovations. Cost-efficiency is achieved by procuring a large number of replacements only when a particular component has reached the end of its service life. This project delivery method will not usually include a design phase because these interventions usually involve replacing building products and systems. DBB, DB and DBM take place all at once and involve design companies, construction companies and maintenance companies. The difference between the three methods is the time frame for the involvement of the different actors and the contractual relationship with the SHO. In DBB, the various contracted parties are involved in the project one after the other, while in DB design companies and construction companies are involved during the same time period, and in DBM all three parties are involved during the same time period. Under DB, the SHO tenders the design and construction work in a single contract and under DBM it tenders the design, construction and maintenance work in a single contract. The contracted entity may be a single company, with or without subcontractors, or a consortium. SBS and DBB are the most commonly used project delivery methods for social housing renovation projects, although DB and DBM are also used for a small number of projects. The vast majority of SHOs use more than one project delivery method simultaneously, mainly a combination of SBS and DBB. For new-build projects, DBB has traditionally been considered the most commonly used project delivery method; however, our survey revealed that it is in fact the second most commonly used project delivery method after SBS. The DBM approach has the maximum potential for delivering energy savings, because it facilitates collaboration between the different actors and promotes their commitment to achieving project goals. Furthermore, DBM offers greater price certainty and less risk of design failure compared to other project delivery methods. However, the project delivery method cannot guarantee the achievement of targeted energy savings by itself. Numerous factors need to be taken into account when considering a change in the project delivery method. The property asset management of the dwelling stock that is renovated using SBS, which focuses on building elements and systems, is completely different from the property asset management of the dwelling stock renovated by DBB, DB or DBM, which focuses on entire properties. It is therefore unlikely that SHOs that are already applying SBS will switch to another project delivery method. Switching between DBB to DBM, or to DB, is feasible since they are similar in terms of property asset management. A change of project delivery method could be motivated by the use of energy performance guarantees offered by energy performance contracting, which is possible in cases where DBM is used. However, this choice is not suitable for all SHOs. For example, if an SHO has an in-house design team and changes to DBM (or DB), its design team will not be involved in the project as the contractor will have its own design staff. If an SHO has a corporate responsibility towards SMEs and changes to DBM (or DB), it will be more difficult to keep SMEs directly involved since they will need to organise themselves into consortia. And finally, if an SHO already has a contract with a maintenance company to manage their entire housing stock, changing to DBM will create a conflict in their maintenance management, since for every property where DBM has been used, a different maintenance company will take charge of maintenance. Energy efficiency in French social housing renovations via Design-Build-Maintain The study is based on the analysis of two social housing renovation projects, implemented by two French SHOs: the renovation of 14 dwellings in a three-storey apartment block in Nurieux-Volognat (in south-eastern France) by the Dynacité SHO; and the renovation of 231 dwellings in four apartment blocks (ranging from 6 to 10 storeys) in Vitry-sur-Seine (in the southern suburbs of Paris) by the Logirep SHO. The data on the case studies were obtained from: the tender documents (call for offers, specifications and preliminary designs); observation during the negotiation phase in the case of Dynacité; interviews, carried out after the construction work was finished, with the social housing renovations manager, the social housing project manager, the construction company, the architect’s office and the maintenance company involved in both cases; and the evaluation reports produced by project managers at the SHOs. The results demonstrate that it is possible to engage design companies, construction companies and maintenance companies to achieve energy savings that exceed those stipulated by the SHO and to obtain a guarantee of results. This approach also makes it possible to shorten the duration of a project, while limiting the costs involved to approximately the equivalent of those incurred in DBB renovation projects. The collaborative set-up of the DBM process also results in improved relations between the actors involved. However, an analysis of these relationships indicated that there is still room for improvement, particularly with regard to the maintenance company. In order to guarantee the benefits of implementing a DBM process, it is necessary for the SHO to put in place the following: realistic but ambitious minimum requirements; clear and measurable award criteria that stress the importance of achieving high energy savings; and a guarantee mechanism that is fair and robust. Moreover, the SHO needs to ensure that the scale of the contract is large enough to guarantee that any compensation paid to non-selected candidates does not adversely affect the total cost of the project and that the SHO’s maintenance strategy must be flexible enough to handle maintenance contracts that are project-related as well as maintenance stock-related contracts. Competitive tenders for integrated contracts for social housing renovation projects The study, which is based on an analysis of eight renovation projects undertaken by SHOs in the Netherlands, shows that Dutch SHOs apply a range of mechanisms in order to influence the ambition, collaboration and long-term view of the consortia that participate in competitive tenders for integrated renovation projects. Their aim is to improve the quality of the construction process and thereby enhance the quality of the output. The scale of the ambition is raised, in first place, through the competitive character of the selection procedure. Several candidates are invited to the tender but only the best will be selected. Secondly, the minimum performance level is defined above common standards by setting high but achievable minimum requirements. Thirdly, the candidates are encouraged to perform at their best by being rated by award criteria that evaluate their performance. The findings show that SHOs are not all singing from the same song sheet when it comes to determining the level of ambition they require from their candidates in relation to the key issue of energy saving. Collaboration is encouraged mainly by setting a very tight deadline for the design proposals, a period of just 11 weeks on average. The consortium members are thus required to work closely together in order to get the proposals out on time and make a convincing pitch in a presentation. The findings show that the procedures with higher numbers of meetings between the SHO and the consortium during the design proposal period appeared to increase collaboration with the SHO. Other mechanisms, such as setting conditions for the nature of the candidates or proposing team coaches, were implemented to a lesser extent and not regarded as appropriate by all SHOs. A longer-term view is promoted by including an optional long-term maintenance contract for the renovated dwellings. The results of this strategy were not as good as expected, however, because the majority of the candidates did not integrate maintenance into their proposal, preferring to make an additional and separate maintenance offer. The SHOs did not include maintenance as an integral part of the renovation project because they were afraid of the possible implications of a long-term maintenance contract on a project basis for their general building stock maintenance strategy and their in-house maintenance teams. The role of the architect using integrated contracts for social housing renovation projects The focus of previous studies is on analysing the implementation of integrated project delivery methods from the demand side, the social housing organisation. However, it has been also identified that the use of integrated project delivery methods have consequences for the supply side actors. Especially for the architect because his central role in the design process could be affected. This study, which is based on the analysis of the role of the architect in thirteen renovation projects that used integrated contracts, concludes that the main role of the architect, as having principal responsibility for the design choices made, does not change when integrated contracts are used. However, the decision-making power of the architect does decrease. With the use of integrated contracts, the main contractor and some specialised contractors can also influence the design choices – an influence that they would not otherwise have. In cases where the main contractor plays an active leading role in the consortium, the reduction of the decision-making power of the architect may become even more evident, and in the opinion of some architects, turn the role of architect into a role more akin to that of technical and aesthetic advisor. The changes in how design decisions are taken do not have a negative impact on the quality of the relationship between the architect and the SHO, and has a positive influence on the quality of the relationship between the architect and the construction companies involved in the project. Some changes were reported relating to the workload for each project compared to Design-Bid-Build projects. In some cases, architects were no longer involved in project management tasks, while in other cases architects were assigned additional responsibilities, such as communicating with tenants. It is not possible, therefore, to establish a direct relationship between the use of integrated contracts and the size of the architect’s workload. Where there is an evident change is in the distribution of the workload and payment for the work done for the integrated contracts that have been tendered through a competitive procedure (seven of the thirteen projects analysed). In projects tendered using a competitive procedure, the work of the architect is condensed into a shorter timeframe (42% shorter than with a non-competitive procedure) and there is a higher risk that the working hours will not be paid in full if the consortium is not awarded the contract. Conclusions In order to improve the performance of energy renovation processes undertaken by social housing organisations, the Design-Build-Maintain project delivery method offers the best opportunity to facilitate the active involvement of all actors, obtain the best possible project performance and to guarantee the quality of the end results. However, given the characteristics of each SHO and the characteristics of the renovation projects, DBM is not always the project delivery method chosen. If DBM is not used, other simpler management mechanisms, such as the early involvement of contractors or the use of in-house maintenance companies as advisors, should be considered to contribute to better process performance. In order to apply the DBM project delivery method successfully, it is necessary for the SHO to focus its efforts on designing a tender procedure that maximises the potential of the entire project delivery method. Choosing a competitive tender procedure that allows the dialogue with candidates.

Optimised project delivery methods forsocial housing energy renovations European Social Housing Organisations (SHOs) are currently facing challenging times. The ageing of their housing stock and the economic crisis, which has affected both their finances and the finances of their tenants, are testing their capacity to stick to their aim of providing decent and affordable housing. Housing renovation projects offer the possibility of upgrading the health and comfort levels of their old housing stock to current standards and improve energy efficiency, and this solution also addresses the fuel poverty problems suffered by some tenants. Unfortunately, the limited financial capacity of SHOs is hampering the scale of housing renovation projects and the energy savings achieved. At the same time, the renovation of the existing housing stock is seen as one of the most promising alternative routes to achieving the ambitious CO2 emissions reduction targets set by European authorities – namely, to reduce EU CO2 emissions to 20% below their 1990 levels by 2020. The synergy between European targets and the aims of SHOs has been addressed by the energy policies of the member states, which focus on the potential energy savings achievable by renovating social housing. In fact, the European initiatives have prioritised energy savings in social housing renovations to such an extent that these are referred to as ‘energy renovations’. Energy renovation is therefore a renovation project with higher energy savings target than a regular renovation project. In total, European SHOs own 21.5 million dwellings representing around 9.4% of the total housing stock. Each SHO owns a large number of dwellings, which means there are fewer people to convince of the need to make energy savings through building renovations, maximising the potentially high impact of decisions. Moreover, SHOs are responsible for maintaining and upgrading their properties in order to continue renting them. As such, SHOs are used to dealing with renovations on a professional basis. The limited financial capacity of SHOs to realise energy renovations magnifies the importance of improving process performance in order to get the best possible outcomes. In the last 30 years numerous authors have addressed the need to improve the performance of traditional construction processes via alternative project delivery methods. However, very little is known about the specifics of renovations processes for social housing, the feasibility of applying innovative construction management methods and the consequences for the process, for the role of all the actors involved and for the results of the projects. The aim of this study is to provide an insight into the project delivery methods available for SHOs when they are undertaking energy renovation projects and to evaluate how these methods could facilitate the achievement of a higher process performance. The main research question is: How can Social Housing Organisations improve the performance of energy renovation processes using more integrated project delivery methods? The idea of a PhD thesis about social housing renovation processes originated from the participation of TU Delft as research partner in the Intelligent Energy Europe project SHELTER1 which was carried out between 2010 and 2013. The aim of the SHELTER project was to promote and facilitate the use of new models of cooperation, inspired by integrated design, for the energy renovation of social housing. The SHELTER project was a joint effort between six social housing organisations (Arte Genova, Italy; Black Country Housing Group, United Kingdom; Bulgarian Housing Association, Bulgaria; Dynacité, France; Logirep, France and Société Wallonne du Logement, Belgium), three European professional federations based in Brussels (Architects Council of Europe, Cecodhas Housing Europe and European Builders Confederation) and one research partner (Delft University of Technology). Research methods This thesis is composed of five studies. The first study is based on a literature review. The second study is based on five case studies from four countries (Belgium, Italy, France and United Kingdom), a questionnaire completed by 36 SHOs from eight countries and 14 interviews with experts from ten countries. The third is based on two French case studies and the fourth and fifth are based on 8 and 13 Dutch case studies respectively. Construction projects in housing involve a high number of professionals and take place over a long period of time. External factors, such as the economic and political situation or changes in construction or procurement regulations, can have a considerable influence on the construction process. Moreover, the specific characteristics of the construction sector of every country can also shape the process. In consequence, there are many interrelated variables that can have an influence on the dynamics of the process and on the outputs achieved. Research that seeks to understand the causes of changes in this process need to dig deeper into the internal and external characteristics of the process, which makes case study research the most appropriate research method for this type of study. The cases in each of the studies have been selected because innovative project management methods aiming for better collaboration between the participating actors were applied and because it was possible to gather high-quality data concerning these projects. The data were gathered mainly through interviews but other methods were also used: a questionnaire, observations and an analysis of tender documents. A protocol based on the recommendations of case study research literature was applied to assure the scientific validity of the data collected through the interviews. The case studies were complemented with a wide-ranging literature review covering scientific publications on project management in construction, mainly from the UK, the US, Australia, the Netherlands, Hong Kong and Finland. Reports from Intelligent Energy Europe projects were also reviewed, as well as legal texts relating to the tender options open to European social housing organisations. Construction management methods How to improve the performance of construction processes has long been and is still one of the key issues of the construction industry sector, social housing included. The performance of construction processes has been addressed from a range of perspectives in the construction management literature and diverse project management methods have been proposed. These methods are interrelated and in constant evolution. Moreover, different terminology is used to describe similar methods, which makes it difficult to obtain a clear picture. To simplify, three main perspectives or methods to improve the process integration and actors collaboration can be identified: the multi-project: supply chain integration; the single-project: integrated project delivery methods; and collaboration: partnering. Supply chain integration looks at the performance of the construction process from a multi-project perspective, relating the construction process to an industrial process. The project delivery method takes a single-project perspective into account because it is based on the premise that the complexity and singularity of any construction project will make it unique. Finally, partnering is focused on the characteristics of collaboration between the actors involved in the construction process. The singularity of renovation projects and the limitations of public procurement make the single project perspective the most feasible strategy for improving the process performance of social housing renovation projects. As such, the analysis of the project delivery methods is the most suitable method for improving the performance of renovation processes. The literature review shows that the more integrated project delivery methods are particularly indicated for construction projects with a high commitment to sustainability in general and for energy performance in particular. The literature review also reveals that the key factor in the process efficiency of all project delivery methods is collaboration between the actors involved in the project. Partnering methods can have a substantial positive influence on process performance. The study of the legal limitations imposed by the currently applicable public procurement Directive 2004/18/EC shows that even though a limited amount of tender options are available, is it possible to tender projects that apply integrated project delivery methods using the competitive dialogue procedure. Moreover, the recently approved but not yet enacted public procurement Directive 2014/24/ EU facilitates even further the use of competitive dialogue tenders for social housing energy renovations. Project delivery methods in European social housing energy renovations This study is based on five case studies, 36 questionnaires and 14 expert interviews, and identified four main project delivery methods for the energy renovation of social housing, namely: Step-by-Step (SBS) Design-Bid-Build (DBB) Design-Build (DB) Design-Build-Maintain (DBM). SBS can be considered a major renovation when the replacement of a series of building components eventually produces the same final result as a renovation project. In order to optimise the service lives of building components, an SHO might choose to split a major renovation project into a series of minor renovations. Cost-efficiency is achieved by procuring a large number of replacements only when a particular component has reached the end of its service life. This project delivery method will not usually include a design phase because these interventions usually involve replacing building products and systems. DBB, DB and DBM take place all at once and involve design companies, construction companies and maintenance companies. The difference between the three methods is the time frame for the involvement of the different actors and the contractual relationship with the SHO. In DBB, the various contracted parties are involved in the project one after the other, while in DB design companies and construction companies are involved during the same time period, and in DBM all three parties are involved during the same time period. Under DB, the SHO tenders the design and construction work in a single contract and under DBM it tenders the design, construction and maintenance work in a single contract. The contracted entity may be a single company, with or without subcontractors, or a consortium. SBS and DBB are the most commonly used project delivery methods for social housing renovation projects, although DB and DBM are also used for a small number of projects. The vast majority of SHOs use more than one project delivery method simultaneously, mainly a combination of SBS and DBB. For new-build projects, DBB has traditionally been considered the most commonly used project delivery method; however, our survey revealed that it is in fact the second most commonly used project delivery method after SBS. The DBM approach has the maximum potential for delivering energy savings, because it facilitates collaboration between the different actors and promotes their commitment to achieving project goals. Furthermore, DBM offers greater price certainty and less risk of design failure compared to other project delivery methods. However, the project delivery method cannot guarantee the achievement of targeted energy savings by itself. Numerous factors need to be taken into account when considering a change in the project delivery method. The property asset management of the dwelling stock that is renovated using SBS, which focuses on building elements and systems, is completely different from the property asset management of the dwelling stock renovated by DBB, DB or DBM, which focuses on entire properties. It is therefore unlikely that SHOs that are already applying SBS will switch to another project delivery method. Switching between DBB to DBM, or to DB, is feasible since they are similar in terms of property asset management. A change of project delivery method could be motivated by the use of energy performance guarantees offered by energy performance contracting, which is possible in cases where DBM is used. However, this choice is not suitable for all SHOs. For example, if an SHO has an in-house design team and changes to DBM (or DB), its design team will not be involved in the project as the contractor will have its own design staff. If an SHO has a corporate responsibility towards SMEs and changes to DBM (or DB), it will be more difficult to keep SMEs directly involved since they will need to organise themselves into consortia. And finally, if an SHO already has a contract with a maintenance company to manage their entire housing stock, changing to DBM will create a conflict in their maintenance management, since for every property where DBM has been used, a different maintenance company will take charge of maintenance. Energy efficiency in French social housing renovations via Design-Build-Maintain The study is based on the analysis of two social housing renovation projects, implemented by two French SHOs: the renovation of 14 dwellings in a three-storey apartment block in Nurieux-Volognat (in south-eastern France) by the Dynacité SHO; and the renovation of 231 dwellings in four apartment blocks (ranging from 6 to 10 storeys) in Vitry-sur-Seine (in the southern suburbs of Paris) by the Logirep SHO. The data on the case studies were obtained from: the tender documents (call for offers, specifications and preliminary designs); observation during the negotiation phase in the case of Dynacité; interviews, carried out after the construction work was finished, with the social housing renovations manager, the social housing project manager, the construction company, the architect’s office and the maintenance company involved in both cases; and the evaluation reports produced by project managers at the SHOs. The results demonstrate that it is possible to engage design companies, construction companies and maintenance companies to achieve energy savings that exceed those stipulated by the SHO and to obtain a guarantee of results. This approach also makes it possible to shorten the duration of a project, while limiting the costs involved to approximately the equivalent of those incurred in DBB renovation projects. The collaborative set-up of the DBM process also results in improved relations between the actors involved. However, an analysis of these relationships indicated that there is still room for improvement, particularly with regard to the maintenance company. In order to guarantee the benefits of implementing a DBM process, it is necessary for the SHO to put in place the following: realistic but ambitious minimum requirements; clear and measurable award criteria that stress the importance of achieving high energy savings; and a guarantee mechanism that is fair and robust. Moreover, the SHO needs to ensure that the scale of the contract is large enough to guarantee that any compensation paid to non-selected candidates does not adversely affect the total cost of the project and that the SHO’s maintenance strategy must be flexible enough to handle maintenance contracts that are project-related as well as maintenance stock-related contracts. Competitive tenders for integrated contracts for social housing renovation projects The study, which is based on an analysis of eight renovation projects undertaken by SHOs in the Netherlands, shows that Dutch SHOs apply a range of mechanisms in order to influence the ambition, collaboration and long-term view of the consortia that participate in competitive tenders for integrated renovation projects. Their aim is to improve the quality of the construction process and thereby enhance the quality of the output. The scale of the ambition is raised, in first place, through the competitive character of the selection procedure. Several candidates are invited to the tender but only the best will be selected. Secondly, the minimum performance level is defined above common standards by setting high but achievable minimum requirements. Thirdly, the candidates are encouraged to perform at their best by being rated by award criteria that evaluate their performance. The findings show that SHOs are not all singing from the same song sheet when it comes to determining the level of ambition they require from their candidates in relation to the key issue of energy saving. Collaboration is encouraged mainly by setting a very tight deadline for the design proposals, a period of just 11 weeks on average. The consortium members are thus required to work closely together in order to get the proposals out on time and make a convincing pitch in a presentation. The findings show that the procedures with higher numbers of meetings between the SHO and the consortium during the design proposal period appeared to increase collaboration with the SHO. Other mechanisms, such as setting conditions for the nature of the candidates or proposing team coaches, were implemented to a lesser extent and not regarded as appropriate by all SHOs. A longer-term view is promoted by including an optional long-term maintenance contract for the renovated dwellings. The results of this strategy were not as good as expected, however, because the majority of the candidates did not integrate maintenance into their proposal, preferring to make an additional and separate maintenance offer. The SHOs did not include maintenance as an integral part of the renovation project because they were afraid of the possible implications of a long-term maintenance contract on a project basis for their general building stock maintenance strategy and their in-house maintenance teams. The role of the architect using integrated contracts for social housing renovation projects The focus of previous studies is on analysing the implementation of integrated project delivery methods from the demand side, the social housing organisation. However, it has been also identified that the use of integrated project delivery methods have consequences for the supply side actors. Especially for the architect because his central role in the design process could be affected. This study, which is based on the analysis of the role of the architect in thirteen renovation projects that used integrated contracts, concludes that the main role of the architect, as having principal responsibility for the design choices made, does not change when integrated contracts are used. However, the decision-making power of the architect does decrease. With the use of integrated contracts, the main contractor and some specialised contractors can also influence the design choices – an influence that they would not otherwise have. In cases where the main contractor plays an active leading role in the consortium, the reduction of the decision-making power of the architect may become even more evident, and in the opinion of some architects, turn the role of architect into a role more akin to that of technical and aesthetic advisor. The changes in how design decisions are taken do not have a negative impact on the quality of the relationship between the architect and the SHO, and has a positive influence on the quality of the relationship between the architect and the construction companies involved in the project. Some changes were reported relating to the workload for each project compared to Design-Bid-Build projects. In some cases, architects were no longer involved in project management tasks, while in other cases architects were assigned additional responsibilities, such as communicating with tenants. It is not possible, therefore, to establish a direct relationship between the use of integrated contracts and the size of the architect’s workload. Where there is an evident change is in the distribution of the workload and payment for the work done for the integrated contracts that have been tendered through a competitive procedure (seven of the thirteen projects analysed). In projects tendered using a competitive procedure, the work of the architect is condensed into a shorter timeframe (42% shorter than with a non-competitive procedure) and there is a higher risk that the working hours will not be paid in full if the consortium is not awarded the contract. Conclusions In order to improve the performance of energy renovation processes undertaken by social housing organisations, the Design-Build-Maintain project delivery method offers the best opportunity to facilitate the active involvement of all actors, obtain the best possible project performance and to guarantee the quality of the end results. However, given the characteristics of each SHO and the characteristics of the renovation projects, DBM is not always the project delivery method chosen. If DBM is not used, other simpler management mechanisms, such as the early involvement of contractors or the use of in-house maintenance companies as advisors, should be considered to contribute to better process performance. In order to apply the DBM project delivery method successfully, it is necessary for the SHO to focus its efforts on designing a tender procedure that maximises the potential of the entire project delivery method. Choosing a competitive tender procedure that allows the dialogue with candidates. Defining performance-based specifications with realistic but ambitious minimum requirements and a set of clear and measurable award criteria that stress the importance of achieving energy savings. Defining a performance guarantee mechanism that is fair and robust. Setting up tender process conditions that facilitate communication between the candidates and the SHO and that promote team working among the candidate team (consortium). The members of the candidate team, the consortium, also need to adapt to the new game rules. Specifically the architect needs to gain more managerial skills in order to keep his leading design decision position and become more of a team integrator. Future research should consider the changes in the roles of the other consortium members and the best consortium structures to ensure a good product quality and the fair treatment of all the parties involved.

In projects tendered using a competitive procedure, the work of the architect is condensed into a shorter timeframe (42% shorter than with a non-competitive procedure) and there is a higher risk that the working hours will not be paid in full if the consortium is not awarded the contract. Conclusions In order to improve the performance of energy renovation processes undertaken by social housing organisations, the Design-Build-Maintain project delivery method offers the best opportunity to facilitate the active involvement of all actors, obtain the best possible project performance and to guarantee the quality of the end results. However, given the characteristics of each SHO and the characteristics of the renovation projects, DBM is not always the project delivery method chosen. If DBM is not used, other simpler management mechanisms, such as the early involvement of contractors or the use of in-house maintenance companies as advisors, should be considered to contribute to better process performance. In order to apply the DBM project delivery method successfully, it is necessary for the SHO to focus its efforts on designing a tender procedure that maximises the potential of the entire project delivery method. • Choosing a competitive tender procedure that allows the dialogue with candidates. • Defining performance-based specifications with realistic but ambitious minimum requirements and a set of clear and measurable award criteria that stress the importance of achieving energy savings. • Defining a performance guarantee mechanism that is fair and robust. • Setting up tender process conditions that facilitate communication between the candidates and the SHO and that promote team working among the candidate team (consortium). The members of the candidate team, the consortium, also need to adapt to the new game rules. Specifically the architect needs to gain more managerial skills in order to keep his leading design decision position and become more of a team integrator. Future research should consider the changes in the roles of the other consortium members and the best consortium structures to ensure a good product quality and the fair treatment of all the parties involved.

En France, au début des années 2000, les changements climatiques commencent à devenir un problème qui compte. Ce qui rend possible cette valorisation publique relève de logiques qui conduisent des agents issus d'univers sociaux divers à s'investir dans un travail politique et collectif de "sensibilisation". Cet impératif qui vise à rendre sensible pour faire prendre conscience, se traduit par une dépolitisation du problème climatique. Il l'individualise en ce qu'il rend surtout visible les responsabilités domestiques. Il l'indifférencie en ce qu'il obscurcit les inégalités sociales de contribution et d'exposition au problème. Il le consensualise en ce qu'il disqualifie les controverses à propos de la responsabilité des comportements individuels. Du point de vue de la production de l'information, cela se traduit par un traitement qui se focalise sur les conséquences du problème climatique plutôt que sur ses causes. La transformation sociologique du groupe de journalistes spécialisés "environnement" au cours des années 1990 favorise ainsi un traitement déconflictualisé des enjeux climatiques. Face à ce dispositif de publicisation, les individus, dotés de dsipositions inégales, se positionnent différemment. D'une part, ils se distinguent en pratique puisqu'en fonction de leurs ressources matérielles, ils ont une propension inégale à émettre des gaz à effet de serre. D'autre part, l'intérêt aux économies d'énergie (et au-delà aux enjeux climatiques) ne revêt ni le même sens, ni la même portée selon qu'il est motivé par des soucis distinctifs de vertu civique ou bien contraint par la nécessité de ne pas trop dépenser. En somme, la sociologie du problème climatique met au jour ses réalités sociales et politiques, là où d'ordinaire, on invite à n'y voir que des faits naturels et individuels.

La place des femmes politiques françaises appréhendée sous l’angle de l’examen des représentations collectives à l’épreuve de la réalité reste relativement peu explorée à ce jour en France, une conséquence probable de « l’exception française » dans le champ politique caractérisée principalement par sa sous-représentation féminine. Une fois l’histoire des femmes politiques retracée, leur silence et diverses discriminations ont été mis en relief. Une partie de cette recherche a été confrontée à des actes lourds politiques définis tels que le premier gouvernement et le second gouvernement Juppé, ainsi que l’élection de Ségolène Royal par les militants socialistes : elle conduit à s’interroger si les vocables employés par les journalistes politiques de la presse écrite divergent en fonction du genre. Si l’on s’appuie sur le postulat que la féminité et la masculinité sont socialement construites, le phénomène de construction, conscient ou inconscient, de la place des femmes dans l’espace public, devient protéiforme. À travers une grille de lecture alimentée par 18 catégories, l’analyse du corpus, composé de 227 articles, permet une étude lexicale qualitative et quantitative. L’hypothèse centrale de cette recherche s’appuie sur l’existence de stéréotypes vis-à-vis de la femme politique stigmatisée par la célérité et la multiplicité des supports véhiculant l’information. En l’occurrence, la problématique à l’égard du genre participerait à la construction (ou à la déconstruction) de stéréotypes pérennes. L’examen des stéréotypes de la femme politique permet d’appréhender certains mécanismes de formation de discrimination à l’égard de l’ensemble des discriminés.

Dans quelles conditions est-il possible de combler un fossé existant entre gouvernants et gouvernés en matière de politique européenne – et dans quelles conditions perdure-t-il à long terme ? Nous avons abordé cette double question en prenant comme exemples la France et l’Allemagne. À l’aide de sept hypothèses, nous avons identifié les conditions dans lesquelles l’ajustement de l’action gouvernementale à l’opinion populaire (« réactivité ») ou bien la persuasion de celle-ci (« leadership ») sont possibles. Nous avons argumenté que si ces conditions ne sont pas réunies, alors un fossé entre les gouvernants et les gouvernés perdure. L’analyse empirique de six études de cas a confirmé la validité des hypothèses. Elle a, de plus, permis de comprendre comment les conditions du succès de la réactivité et du leadership varient selon les contextes politiques et culturels : le système politique français a tendance à faciliter l’ajustement du gouvernement sur l’opinion populaire, tandis que le système politique allemand favorise un leadership efficace. La discussion des résultats empiriques a aussi montré que le rapprochement entre les gouver¬nants et les gouvernés en matière de politique européenne est souvent difficile : le manque d’alternatives politiques empêche fréquemment les gouvernants d’être réactifs et il n’est pas rare que des dissensions au sein des élites politiques rendent le leadership impossible. Par sentiment de manquer d’influence, et en raison de l’insuffisance du travail de persuasion, les citoyens tendent à s’éloigner toujours plus du processus de l’intégration européenne
Sometimes, national governments pursue a European policy which is not in line with the preferences of their citizens. Under what conditions such a gap between government and people can be bridged – and under what conditions it persits? This doctoral thesis examines this double question using the example of France and Germany. It develops seven hypotheses concerning the conditions of responsiveness (governmental action follows popular preferences) and of leadership (popular preferences follow governmental action). If neither repsonsiveness nor leadership is possible, a gap between government and people cannot be bridge, the thesis argues. The empirical findings confirm the hypotheseses. They show furthermore that varying political and cultural contextes offer varying chances of success for responsiveness and leadership : The French political system favours responsiveness whereas the German political system favours leadership. Moreover, the empirical findings show why it is often difficult to bridge the gap between government and people in European politics : Frequently, a lack of political offer hinders responsiveness and, at the same time, a lack of coherency within the political elite hinders effective leadership. These circumstances risk to alienate the wider public more and more from the process of European integration

Les échanges entre la Chine et la France ne cessant de se développer, les représentations construites au travers de divers contacts et mobilités deviennent une problématique importante. Notre recherche porte sur les représentations des Chinois sur la France, les Français et la langue française, et sur les facteurs intervenant dans le processus de ces représentations. Cette étude privilégie l’entretien semi-directif comme recueil de données, croise l’expérience de six groupes de Chinois qui ont des expériences de mobilité étudiante, professionnelle ou d’émigration en France. L’analyse des entretiens s’effectue sur deux niveaux : une analyse thématique au niveau macrosocial, destinée au décodage socioculturel, et une analyse biographique au niveau microsocial, pour s’interroger sur l’influence majeure de la trajectoire. Cette étude avance enfin des propositions pédagogiques en vue de la construction d’une compétence interculturelle
Because the exchanges between China and France keep on developing themselves, the representations built thanks to the different contacts and mobility are beginning to be an important problematic. The subject of our research is Chinese representations of France, French and the French language, and the factors occurring in the process of these representations. This study prioritises the half-directed interview as collection of data, crosses the experiment of six groups of Chinese who have experienced mobility to France in order to study, to emigrate or for professional reasons. The analysis of these interviews applies on two levels: a thematic study on the macro-social level dedicated to the sociocultural decoding, and a biographic study on the micro-social level in order to wonder on the majeur influence of the trajectory. Finally, this study advances educational propositions with the aim of the construction of an intercultural competence

L'image du Burkina Faso dans les médias français, les hebdomadaires en particuleir, ne semble pas donner la mesure des progrès de toutes sortes par ailleurs quantifiables que ce pays enregistre aujourd'hui, et qui sont reconnus et salués par la communauté internationale. Comment, entre 1998 et 2008, l'information en provenance du Burkina Faso a-t-elle été traitée par les grands hebdomadaires français. L'étude des titres : " Le Point, L'Express, Le Nouvel Observateur, Marianne et Courrier international" est confrontée aux réalités complexes de ce PMA africain, dont on sait qu'il compte parmi les cinq pays les plus pauvres du monde. Une anlyse des responsabilités des organes de presse, et de celles des journalistes, permet de déterminer la marge de manoeuvre dont peut bénéficier tout rédacteur ou "reporter" français lorsqu'il aborde l'actualité burkinabé. Un retour sur le traitement médiatique de l'ex-Haute-Volta dans ces mêmes hebdomadaires depuis la naissance des premiers "newsmagazines" français, en 1964, aide à mettre en lumière les origines de ce conformisme journalistique, et démontre que les idéologies politiques comme les activismes radicaux jouent un rôle déterminant dans la restitution de cette actualité. Les constats formulés tout au long de cette analyse à partir des hebdomadaires français sont mis en perspective dans une dernière approche des autres médias hexagonaux: quotidiens nationaux et régionaux, mensuels, radios et chaînes de télévision.

A travers le prisme d’articles parus dans la presse écrite française, nous réfléchissons à la question de l’opinion publique en Chine entre l’été 2007 et la fin 2010. L’objectif est double : d’une part appréhender l’opinion publique en Chine et d’autre part envisager l’opinion publique en France sur la Chine. L’opinion publique en Chine transperce dans des aspects sociaux. Pour mieux réfléchir à la question, il importe de comprendre les conditions mêmes de l’élaboration de l’opinion publique : l’évolution du contexte chinois et de son image internationale, la mouvance économique qui fait osciller la population entre tradition et modernité…Divisée entre capitalisme et communisme, la Chine est soumise à des inégalités importantes. L'analyse examine la vie sociale et politique, et l'opinion que les Chinois ont d'eux mêmes et du monde qui les entoure. Enfin, le regard occidental sur la Chine amène à la question de la démocratie. Le nombre récurrent d’émeutes est-il l’indice d’une volonté de démocratisation ? La Chine nourrit ainsi des illusions occidentales qui voient dans la démocratie la solution universelle. Le gouvernement chinois lui-même utilise régulièrement le terme de démocratie, mais « à la chinoise ». Dès lors une vision synthétique de la probabilité d'évolution de la politique chinoise est discutée. Est-il possible de conjuguer socialisme et démocratie ou bien la Chine s’achemine-t-elle vers une acculturation du Régime actuel ? Par ailleurs, l’étude étant basée sur les articles de la presse écrite française, il apparaît utile de se poser la question de la partialité de ce média. Qualitativement, quantitativement…quels sont les thèmes de l’opinion chinoise dans la presse écrite française ? Les articles sont-ils nombreux ? Qui écrit, à quelle fréquence ? Il saura apparaître que la Presse peut être assez partisane et structure l’opinion publique française. Or, une meilleure communication, plus ouverte sur la Chine, paraît absolument essentielle
Through the prism of articles edited in the French print media, we think about the question of the public opinion in China between the summer 2007 and the end of 2010. The objective is double: on one hand understand the public opinion in China and on the other hand comprehend the public opinion in France on China. The public opinion in China pierces in social aspects. To think better about the question, it is important to consider the conditions of the elaboration of the public opinion: the evolution of the Chinese context and its international image; the economic sphere of influence which makes the population oscillate between tradition and modernity … Divided between capitalism and communism, China is suffering from important disparities. The analysis examines the social and political life, and the opinion the Chinese have of themselves and of the world which surrounds them. Finally, the western glance on China leads to the question of the democracy. Is the recurring number of riots the indication of a will of democratization? China feeds western illusions which see in the democracy the universal solution. The Chinese government itself regularly uses the term of democracy, but "Chinese-style". From then a synthetic vision of the probability of evolution of the Chinese politics is discussed. Is it possible to conjugate socialism and democracy either does China move towards an acculturation of the current Regime? Besides, the study being based on articles of the French print media, it seems useful to ask the question of the partiality of this media. Qualitatively, quantitatively what are the themes of the Chinese opinion in the French print media? Are articles many? Who writes, with which frequency? It will appear that the Press can be rather partial and structures the French public opinion. Yet, a better communication, bigger and more opened on China seems absolutely essential

Cette thèse se propose d'analyser les formes du discours de la presse politique nationale française concernant les immigres et l'immigration, de 1974 a 1984. Une première partie analyse les formes extérieures du discours : nombre d'articles par années, rubriques et genres, type d'événements rapportes. La seconde partie utilise les méthodes lexico métriques, et en particulier les analyses de spécificité lexicale, elle dégage des systèmes de désignation de soi et de l'autre assez hétérogènes, mais qui permettent des glissements d'un journal a d'autre. La troisième partie est d'abord la mise en œuvre d'une méthode d'approche nouvelle des corpus chronologiques; elle permet d'opposer les années 70 ou l'ensemble de la presse traite des "travailleurs immigres", en foyer ou en situation de travail, et les années 80 ou le regard se porte sur l'immigre comme source de problèmes pour les français. La négativation progressive de la question est générale. Elle est à relier à l'absence de perception solide de soi et de l'autre. Seules les extrême-droite et extrême-gauche ont un système désignatif cohérent et ne modifient guère leur approche de la question immigrée au cours des années étudiées
This thesis aims to analyse forms of French national political press dealing with immigrants and immigration (1971-1984). The first part studies outward forms of discourse: number of articles written each year, columns and genres, kinds of events related. The second part, with lexicometric methods, and specially analysis of the specific vocabulary, shows that systems of designation of oneself and of the others are different enough from one newspaper to an other, but also similar enough to allow many skidding. In the third part, a new way to study "chronological" corpus is tested; it opposes the seventies to the eighties: in the former, the whole press speaks about immigrants as workers, or living in collective homes; in the latter, immigrants are seen as the source of problems for French people. The fact that the issue is progressively negated is general. It must be connected with the absence of clear perception of oneself and of the others in most newspapers. Only the extreme-right press (militant et le national) and the left wing press has a coherent system of designation; so they do not change their way of seeing the subject of immigration between 1974 and 1984

L'etude est consacree a l'opinion publique alsacienne devant la construction de l'europe durant la periode de 1945 a 1950. Compte tenu de la situation particuliere de l'alsace, elle essaie de cerner l'evolution de cette opinion en rapport avec les divers elements constituant le particularisme alsacien. La designation de strasbourg, capital de l'alsace, comme siege du conseil de l'europe en fevrier 1949 donnant a l'opinion publique alsacienne une nouvelle dimension en matiere de construction europeenne, l'idee de faire l'europe devient desormais un sujet d'actualite en alsace. En meme temps, l'opinion publique alsacienne evoque de plus en plus le particularisme culturel de la region, et cela, cette fois-ci dans une perspective europeenne. L'etude montre que l'opinion publique alsacienne exprime ses particularites sur le sujet liees a sa double culture et son passe trouble par des vicissitudes historiques entre la france et l'allemagne. Elle met aussi en evidence l'existence d'un courant tres favorable et original a l'egard de la construction de l'europe de cette epoque
The thesis is consecrated to the alsatian public opinion faced with the european integration from 1945 to 1950. Taking into account of the alsatian specific situation, it tries to define the evolution of this alsatian public opinion from the point of view of the various alsatian specific caracteristics. The choice of strasburg, capital of alsace, as the headquarter of the council of europe in february 1949 has given a new dimension to the alsatian public opinion toward the european integration. From that time, the european idea becomes one of the most important actualities in alsace. In the same time, the alsatian sense of identity considered as a positive factor for europe begins to be more and more debated in relation with the european integration. The study shows that the alsatian public opinion expresses its specific situation tied with its double culture and its troubled past due to historic vicissitudes between france and germany. It makes also sure the existence of a very favourable and original european idea in alsace during this period

ACette étude a pour objectif l'analyse du contenu de la presse française, plus précisément de trois quotidiens parisiens (le Figaro - le Monde - Libération) et de leurs attitudes vis-à-vis du Liban et de ses évènements pendant la période 1982-1986. Les trois évènements les plus marquants de cette période (1982-1986) sont les suivants : i. L'invasion israélienne au Liban et ses conséquences. Ii. Le conflit libano-libanais ou la guerre civile. Ii. Les otages français au Liban. La recherche comprend, d'une part, une analyse de la forme, c'est-à-dire l'analyse de la mise en valeur de l'évènement, par chacun des trois journaux et, d'autre part, l'analyse du message, c'est-à-dire l'analyse thématique du texte tel qu'il est présente dans chacun des trois journaux. Notre recherche s'articule donc sur trois axes principaux : la mise en valeur de l'évènement, l'analyse thématique de son contenu et l'analyse des stimulations affectives qu'il offre
AThe purpose of this research is to analyze the contents of three parisian newspapers (le Figaro - le Monde - Liberation) in order to know their attitudes towards the events that occured in lebanon betwen 1982 and 1986. The most important events during this periode are the following : - the israeli invasion of Lebanon and its consequences 1982-1983. - the lebanese conflict or the civil war (1983-1985). -the french hostages (1985-1986). This research includes three principal studies : -form analysis or a study of the news structure (headlines, leads location of the news in the papers, front page, volume occupied by the lebanese information and the information sources). -thematic analysis of the contents of each newspaper. -affective stimulation analysis (terminological study or study of the vocabulary used)
