Ce travail questionne dans quelle mesure et par quels processus la nécessité dans laquelle sont les acteurs s’opposant à un projet d’aménagement de devoir argumenter leur refus peut participer incidemment à la diffusion de valeurs, de croyances et de principes caractéristiques du militantisme environnementaliste. Poursuivant une ligne d’analyse simmelienne, cette thèse rapproche les dimensions interactionnistes et cognitives des conflits d’aménagement pour saisir comment les propriétés de l’argumentation et de l’engagement de groupe peuvent progressivement conduire des acteurs initialement engagés à s’opposer à un projet d’aménagement en raison de motivations personnelles à assumer et à promouvoir des contenus environnementalistes, défendus pour eux-mêmes et au delà du conflit d’aménagement initial. Nous proposons un modèle analytique du rôle de l’argumentation dans le développement du militantisme environnementaliste dans la situation où des individus forment un groupe pour s’opposer à un projet d’aménagement sur la base d’un argumentaire commun. Ce modèle est forgé à partir du versant simmelien des travaux de Bernard Groethuysen et Mikhaïl Bakhtine. Le cadre empirique de cette étude est celui des conflits nés de l’aménagement d’une centrale hydroélectrique à Saint-Chamas (Bouches-du-Rhône) qui fait de l’étang de Berre le point de chute d’une des plus importantes chaînes hydroélectriques de France. Lors de ces conflits, la progression de l’argumentation et les interactions qui l’accompagnent rendent possible l’extension de la mobilisation à des thématiques environnementales diverses et à la défense de nouveaux écosystèmes. / This work questions how far and by what processes the constraint made to the social actors who are opposing an industrial or urban development project to argue their refusal can incidentally contribute to the dissemination of the values, beliefs and principals of the environmentalist activism. Following a simmelian analysis perspective, this work makes converge the interactionist and cognitive dimensions of the planning conflicts. By this way we aim to understand how the properties of arguments and group commitments may gradually lead actors initially engaged to oppose a development project due to personal reasons to assume and promote environmentalist contents defended for themselves and beyond the initial development conflict. We propose an analytical model of the role of argumentation in the development of environmentalist activism when individuals decide to constitute a group in order to oppose a development project by means of a common argumentation. This model is made from the simmelian aspects of the works of Bernard Groethuysen and Mikhail Bakhtin.The field study of this work is consituted by the conflicts arising from the construction of a hydroelectric power station at Saint-Chamas (Bouches-du-Rhône) which converted the Berre lagoon into the point fall of one of the leading french hydroelectric chains. During these conflicts, the progression of argumentation and the interactions involved in the argument process allow the expansion of the mobilization to various environmental issues and the defense of new ecosystems.

The psychological aspects of sports is crucial for performance and important for sustaining good mental health. Despite this, efforts to improve those aspects are surprisingly rare and partly due to stigmatization of help-seeking together with lack of time and economic resources. However, in recent decades much research on internet-based interventions have been conducted. Also, a growing body of empirical support for the Mindfulness-Acceptance-Commitment approach (MAC) related to enhancement in performance and mental health in sports has emerged. This study was the first to explore the effects of internet-based MAC, which was conducted with the digital self-care programme ACTSPORT with or without feedback. Of 193 participants (aged 18 - 71, from 40 different sports on a variety of levels) who were randomly assigned to feedback, non-feedback and waitlist group, 125 completed the study. The results showed that participants who completed ACTSPORT with feedback experienced significantly enhanced performance, reduced performance anxiety and improved mental health, which included higher quality of life and less symptoms of depression. These improvements were predicted by significant improvements in acceptance and dispositional mindfulness. A larger effect was found for participants with feedback which indicated that some support is preferable. In conclusion, the present study indicate that internet-based interventions in sport may be  effective, time-saving, cost-effective, flexible and available means for both enhancement in performance and aspects of mental health. / De psykologiska faktorerna inom idrott är avgörande för prestation och viktiga för att upprätthålla god mental hälsa. Trots detta är ansträngningar för att förbättra dessa faktorer förvånansvärt sällsynta. Det beror bland annat på att det råder ett stigma kring att söka hjälp samt brist på tid och ekonomiska resurser. De senaste decennierna har det genomförts en stor mängd forskning på internetbaserade interventioner. Dessutom har Mindfulness-Acceptance-Commitment approach (MAC) fått en ökad mängd empiriskt stöd gällande förbättring i prestation och mental hälsa inom idrott. Föreliggande studie är den första i sitt slag att undersöka effekten av internetbaserad MAC, vilken genomfördes med det digitala självhjälpsprogrammet ACTSPORT med eller utan feedback. Av 193 deltagare (ålder 18 - 71, i 40 olika sporter på alla nivåer) som randomiserades till tre grupper med feedback, utan feedback eller väntelista, fullföljde 125 deltagare studien. Resultaten visade att deltagare som fullföljde ACTSPORT med feedback upplevde signifikant förbättrad prestation, minskad prestationsångest såväl som förbättrad mental hälsa vilket inkluderade högre livskvalité och minskade depressionssymtom. Detta visade sig kunna prediceras av signifikanta förbättringar i acceptans och dispositionell mindfulness. En större effekt sågs för deltagarna i gruppen med feedback vilket indikerade att ett visst stöd är fördelaktigt. Slutsatser från studien är att internetbaserade interventioner inom idrott kan vara effektiva, tidsbesparande, kostnadseffektiva, flexibla och tillgängliga medel för att både öka prestation och aspekter av mental hälsa.

Information and Communication Technology is used in the education field in Sweden toimprove learning quality. The aim of this research is to investigate the use of LearningManagement Systems in primary schools, in the specific context of the role of LearningManagement System (LMS) in learning and teaching processes from teachers‟perspectives. Furthermore, This Thesis aims to explore teachers‟ perceptions of how touse this learning management system which is used in primary Swedish schools.Six teachers from two different primary schools in small municipality in the south ofSweden participated in semi-structured interviews. The theoretical model of UnifiedTheory of Acceptance and Use of Technology (UTAUT) inspired this qualitativeresearch along with the other related past studies. This quantitative model was only usedto sensitize the research process, for collecting and analysing qualitative data in thisstudy.The different elements of the theory such as performance expectancy, effort expectancy,social influence and facilitating conditions along with studies helps in conducting studybasedon qualitative approach for analysing the interviews. The research results indicatethat teachers were content with the usage of this learning management system, but thereis a lack of knowledge regarding this system. The system is helpful in performanceevaluation, planning, communication and overall working for routine tasks. Theresponses of interviews showed that teachers are not trained for using the features ofLearning management system in the way that it is designed for. The findings showed thatteachers require the support from professionals to integrate the system into their routineplanning. Furthermore, they also emphasise on the need to make the system user-friendlywith easy navigation. The findings of this study were compared to previous studies, anda further comparison was carried out regarding how it relates to the determinants andmoderating factors such as peer influence, internal perceptions and motivations, timeconstraints, organisational structure and facilitating conditions. Hence, support andtraining are needed to enhance learning and teaching through this Learning managementsystem.

Responding to globalization and its effects on education and research development, the Thai government decided to push all public universities to become autonomous and establish a system of quality assurances. The establishment of quality assurances has had a large impact on many Thai instructors, especially in new public universities. Thai instructors are now forced to more focus on conducting research because the number of research publications is regarded as one of the main criteria for quality universities. The purpose of this study is to investigate the key factors, at the individual and university levels, which impact on the instructors' behavior in conducting research of the full-time instructors in the faculty of Management Science from the Rajabhat Universities in Thailand. The current study will help explain how and why the instructors accept or refuse to conduct research and provide insight into the salient factors motivating the instructors to produce more research by conducting HLM. Data were collected from 694 participants at 37 institutions via a questionnaire survey. The findings revealed that there was no difference among these 37 universities on behavior in conducting research. The key factors statistically influencing behavior in conducting research of the instructors were facilitating conditions, academic degree, social influence, and usefulness as well as ease of conducting research that the instructors perceived. This study gained 46% of effect size.

Pathologische Sorgen sind ungenau definiert. Für die Behandlungsplanung bleiben wichtige Fragen offen: Welche Merkmale sind für die Unterscheidung zwischen behandlungsbedürftigen und nicht behandlungsbedürftigen Sorgen relevant? Welche Art von Sorgen muss wie behandelt werden? Und: Welche Art von Sorgen gilt es eher zu akzeptieren? Wir machen praxisnahe Vorschläge dafür, wie Sorgen mittels einer einfachen Heuristik auch vom Patienten selbst als «pathologisch» identifiziert werden können. Im Sinne eines therapeutischen Arbeitsmodells ergeben sich differentielle Bearbeitungsstrategien, je nachdem, ob es sich um wichtige oder weniger wichtige, auf lösbare oder unlösbare Probleme bezogene sowie angemessene oder überzogene Sorgen handelt. Das vorgestellte Arbeitsblatt zu den Sorgen soll vor allem die wahrgenommene Kontrolle des Patienten stärken und die Psychoedukation zur Generalisierten Angststörung erleichtern. / Pathological worries have not yet been clearly defined. As a consequence, practically relevant questions remain open: Which characteristics distinguish worries relevant for treatment from those which are not? What kind of worries has to be treated in which way? And: What kind of worries is rather to be accepted? We propose a simple rationale which helps the therapist and the patient to identify pathological worries. According to this working model, different treatment strategies result depending on whether worries are central or not, whether they relate to a problem which can be solved or not, and whether they seem proportionate or exaggerated. The presented worksheet is meant to strengthen the perceived control of the patient and to help facilitate psychoeducation for generalised anxiety disorder. / Dieser Beitrag ist mit Zustimmung des Rechteinhabers aufgrund einer (DFG-geförderten) Allianz- bzw.

There was a lack of knowledge about the user’s acceptance of smart devices as ubiquitous learning (u-learning) tools at higher education institutions in Sweden. As the mobile technology grows, the demand for mobile devices, particularly smart devices increases as well. With the increase in the usage of smart devices, the higher education institutions provide mobile learning platforms to attract more customers in the competitive industry of education. Thus, understanding the key factors from the perspectives of end-users is important for the institutions to survive in the competitive market. This study explores and explains Behavioral and Continuance intentions of students regarding the acceptance and usage of smart devices (Smartphones and Personal Digital Assistants or PDA) as u-learning tools. Key factors related to the users’ intentions to accept and continue using smart devices as u-learning tools were identified and hypothesized in the Swedish context. Ten hypotheses were suggested based on TAM, UTAUT, and ECT. To achieve the aim and objective of this study, a quantitative approach was chosen, and a survey strategy based on purposive and convenience sampling techniques were used. A web-based questionnaire on five-points Likert Scale was designed to collect the required data. 115 (96 valid) students answered the questionnaire. The collected data were used to conduct statistical operations in SPSS. Five hypotheses were supported, and the other five were not. The findings suggest that Performance Expectancy, Perceived Mobility value, Confirmation, and Satisfaction positively influence both Behavioral and Continuance Intentions of students to accept and continue using smart devices as u-learning tools. According to the findings, Confirmation and Satisfaction from ECT can be included as separate constructs in UTAUT and UTAUT2. Higher education institutions planning to have (and those that already have) learning platforms, compatible with smart devices, can benefit from the findings. Higher education institutions can also design their u-learning platforms according to the Performance Expectancy, Perceived Mobility value, Confirmation, and Satisfaction of the students. / Master program in Strategic-IT Management

Objectives: The World Health Organisation has predicted that by 2020, brain injury will be one of the leading causes of disability in the world (Hyder et al, 2007). Psychological difficulties are common in this population, with up to 60% of individuals experiencing mental health difficulties (Acquired Bain injury Outreach Service, 2012). Therefore, with the rapid rise in referrals, services are under increasing pressure to provide innovative ways of offering effective and cost-efficient care. This research aimed to evaluate a novel transdiagnostic Acceptance and Commitment Therapy group approach for supporting individuals adjusting to life following the diagnosis of a neurological condition. Methods: A mixed-methods waiting-list control design was used and carried out across two sites of Hertfordshire Neurological Outpatients Service. The outcomes of the group were assessed using four outcome measures evaluating acceptance, self-identified difficulties, low mood and anxiety, as well as a semi-structured interview to identify mediators of change. Results: Ten participants from the intervention group completed, equating to a 76.9% completion rate. The results indicated that those in the intervention group made significant improvements across all measures of acceptance, self-identified difficulties and psychological distress. Those in the waiting list groups did not experience any change in these domains. The qualitative feedback from participants was also highly positive. Participants reported the usefulness of the ACT strategies, in addition to valuing being in a group with others with a range of difficulties. Participants reported greater awareness and acceptance, as well as increased activity and improved mood. Conclusions: The ACT group is a potentially effective and cost-efficient method of supporting individuals with adjustment following diagnosis of a neurological condition. Despite these promising findings it is important to acknowledge the limitations, such as the small sample size and research design. Further research would be beneficial in order to evaluate the intervention using more rigorous methods.

Internal marketing and internal communication are essential tools to align em-ployees’ mindsets with the necessary tasks which bring about employee satis-faction and organisational prosperity. Electronic newsletters serve as an internal marketing communication medium which can convey the necessary information to employees regarding the organisation’s goals and objectives. They also act as a medium to build relationships with employees and encourage improved service delivery and customer-oriented employee mindsets. Employees’ willingness to make use of electronic newsletters for the purpose of disseminating organisational information is an indication of employees’ acceptance of the organisational information and use thereof in performing organisational tasks successfully as the organisation intends. The purpose of the current study was to determine employees’ acceptance of electronic newsletters, as an internal marketing communication medium, in order to disseminate organisational information which contributes to the attainment of organisational goals, objectives and success. An empirical study was conducted to determine employees’ acceptance of elec-tronic newsletters by means of an adapted technology acceptance model, self-administered, e-mail survey disseminated to employees of a higher education institution. The study followed a quantitative research approach, utilising re-gression in the analysis of the data. Based on the research results, employees do accept the electronic newsletter for the dissemination of organisational information, albeit with suggestions on how it can be better utilised in future. / Business Management / M.

Ett konsultföretags digitala samarbetsyta för projekthantering används inte i den utsträckningsom företagsledningen önskar och de misstänker att detta grundar sig i ett dåligt gränssnitt ochlåg användbarhet hos systemet. Etablerade teoretiska modeller föreslår att användarbeteendengrundar sig i intentioner. Dessa bygger i sin tur bland annat på attityden mot beteendet, subjektivanormer gentemot beteendet och specifikt för teknikanvändning även systemets värde ochmöjligheterna att få hjälp att använda det. Utifrån detta ställdes följande frågeställningar: (1)Beror det låga användandet på dålig användbarhet? (2) Beror det låga användandet påsubjektiva normer och attityder? (3) Finns det någon koppling mellan ett systems användbarhetoch användarnas vilja att använda det? Nio personer ur användarmålgruppen intervjuades ochfick genomgå användbarhetstester på systemet, vilket sedan utvärderades med SUS-enkäter.Systemets användbarhet konstaterades vara oacceptabel och nyttan det medför väger inte uppför ansträngningarna vid användande. Deltagarnas attityd gentemot systemet var överlagnegativ och byggde till stora delar på arbetsplatsens sociala kultur, då nyttan i systemet döljs avdet låga användandet. Genom korrelationsanalyser kunde inget samband mellan användbarhetoch viljan att använda påvisas. I intervjuerna framkom dock att användbarheten är en avgörandefaktor för viljan att använda. Dessa två företeelser är således inte direkt beroende av varandra,men samspelar under påverkan av andra faktorer. / The digital platform for internal cooperation within a consulting company is not used to theextent that the management wishes, something they suspect is caused by poor usability.Established theoretical models suggest that user behavior is controlled by intentions, which arebased on the attitude towards the behavior, as well as subjective norms. Specifically regardingtechnology usage, the value in using the system and the availability of guidance, are determiningfactors. From this, the following three research questions were formulated: (1) Is thelow usage caused by poor usability? (2) Is the low usage caused by subjective norms andattitudes? (3) Is there a connection between the usability of a system and the users’ intentionsto use it? Nine target users were interviewed and participated in evaluating the system throughusability testing and SUS surveys. The usability was considered unacceptable and the value ofusing it did not outweigh the effort during interaction. The attitude towards it was mainlynegative, primarily due to the social culture of the working place, with few current usersconcealing the value of usage. No connection between usability and the intention to use couldbe found through correlational analysis. From interviews, however, usability was identified asa determining factor for the intention to use. Thus, these phenomena do not directly affect eachother, but interact along with other factors.

Welche E-Learning- und Social Web-Anwendungen nutzen Studierende innerhalb ihres Studiums und aus welchen Gründen tun sie dies? Die folgende Masterarbeit widmet sich dieser Fragestellung. Unter der Einbeziehung des Technology-Acceptance-Models (TAM) und dem Uses-and-Gratification Ansatzes werden Nutzungsmotive aus dem Forschungsstand herausgearbeitet und empirisch getestet (Studierende der TU Dresden, n=1242). Studierende nutzen demnach Anwendungen für das Studium, die sie auch schon im alltäglichen Leben verwenden. Besonders im Bereich der Zusammenarbeit sowie zur Kontaktaufnahme zu Kommilitonen werden Anwendungen aus der Freizeit genutzt. Unverzichtbar für das Studium ist für die meisten Studierenden die Nutzung des Lernmanagementsystems, welche zumeist von Dozenten vorgeschrieben ist. Nur so ist es den Studierenden möglich, auf bestimmte Lerninhalte, die für das Bestehen des Studiums notwendig sind, zuzugreifen. Die Arbeit leistet einen Beitrag zur Beforschung des Mediennutzungsverhalten von Studierenden. Die Ergebnisse können wiederum für die Strategieentwicklung im Bereich des Einsatzes von Lehr- und Lerntechnologien in der Hochschule nützlich sein.
