The intention of this study is to give a qualitative and quantitative description of the usage of connectors, especially mais, parce que and donc, and of some epistemic modifiers in the spoken French of Swedish advanced learners. The study includes eight advanced learners, six highly advanced learners and eight native speakers from the French learner corpus InterFra, all interviewed by the same native speaker. In total, 22 interviews of learners (39,000 words) and eight interviews of native speakers (23,000 words) were examined. One of the goals was to find typical advanced learner features (interlanguage features) in connector and modifier usage, and also to describe individual variation in the group. We highlight the importance of comparative studies and of taking into account recent studies of spoken French to establish advanced interlanguage features, as normative French grammar fails to account for some spoken usage of connectors. The aim in studying interlanguage features that involve connectors and modifiers is twofold: first, we try to understand the function of certain connectors/modifiers at the semantic, discourse organizing, interactional and speech act levels. Second, we look at the syntactic dependence and integration of discourse sequences introduced by parce que and modifiers like je crois (que). The study of mais (chapters 2 and 3) showed that learners used turn-introducing mais more often than native speakers. Mais was also found to be an important reformulation marker in the learner group. In the study of parce que (chapter 4), we found that the macro-syntactic (paratactic) parce que was frequent in both speaker groupes, but that a function like introducing ”specifications” was more frequent in the learner group, while parce que introducing parenthetic remarks (incises) – commonly used by native speakers of French – was found in only a few cases in the learner corpus. We suggest that this latter usage is a property of the highly advanced user. The study of epistemic phrases like je crois/ je pense/ je trouve (que) (chapter 5) revealed a small quantitative difference in syntactic dependence between the two groupes of speakers: the learners more frequently used independent expressions. From a qualitative point of view, the difference was partly due to the high number of isolated phrases (like je crois oui) and post-positioned phrases in the learner material. Both groups of speakers used modifiers as discourse-structuring devices and as fillers, but their use as fillers was more frequent in the learner group. Finally (chapter 6), by carrying out a prosodic analysis (variation in fundamental frequency) coupled with an analysis of the information structure, we segmented the speech into functional discourse units (les paragraphes oraux). This analysis suggested some characteristics of highly advanced learner usage for the position of the connector donc. One such feature was the incorporation of donc in a constituent of the discourse unit, both from a syntactic and prosodic point of view.

Undoubtedly, there are many factors influencing IT-usage at work; some of them are psychological. The thesis provides new knowledge about the connections between three phenomena: IT-usage, self-efficacy and creativity among Swedish news journalists. The dissertation also contributes new knowledge about the mechanisms of self-efficacy in IT-related work. The first objective was to explore psychological factors’ influence on how, when and why IT is used at work. In particular, the investigation aimed to study the role of self-efficacy in IT-usage. The second objective was to examine the relationship between IT-usage and creativity. Of specific interest was whether journalists perceive IT-technologies as a support or an obstacle. The empirical findings of four studies show a complex picture. Variation in IT-usage and communication at work is explained by factors as attitudes, experience of IT-usage, interest in traditional journalistic work, and IT-specific self-efficacy. Furthermore, the results reveal that both generalized work self-efficacy and IT-usage at work are related to perceived creativity among news journalists. / Diss. Stockholm : Handelshögsk., 2004

Le changement de l'occupation des sols (LUC) a une influence importante sur le climat de par les modifications des propriétés physiques de la surface. Le niveau de connaissance de ces impacts biogéophysiques est cependant insuffisant, en raison notamment des nombreux processus impliqués. Via l'intercomparaison de modèles de climat et d'autres outils développés, cette thèse vise à identifier les signaux climatiques robustes liés au LUC, ainsi qu'à évaluer les incertitudes associées. Depuis l'époque préindustrielle, le LUC a résulté en une déforestation extensive dans les régions tempérées de l'hémisphère Nord, où l'augmentation de l'albédo de surface a sûrement induit un refroidissement durant l'hiver et le printemps. L'amplitude de cet impact ainsi que le rôle des effets non radiatifs en été reste pourtant très incertain parmi les modèles. Ces incertitudes répondent (1) à la façon dont le LUC est représenté dans les modèles de surface et (2) aux sensibilités intrinsèques des modèles de climat au LUC. Le deuxième point explique plus de 50% de la dispersion inter-modèle dans des variables clés au climat de surface comme l'évapotranspiration. Suite à cette incertitude, les impacts du LUC dans albédo de surface et l'évapotranspiration ont été estimés à partir d'observations contemporaines et les cartes de végétation prescrites dans les modèles de surface ici évalués. L'ensemble de ces analyses montre que les incertitudes actuelles des effets sur le climat du LUC sont en grande partie liées aux paramétrisations des modèles de surface, et peuvent donc être réduites par une évaluation plus rigoureuse de ceux-ci.

While the introduction of the Internet in the past 20 years has revolutionized the way people manage established firms, little is known about the effects of the Internet on the rate of new firm entry. Since government regulations have been identified to be one of the primary determinants of firm entry rates, this paper uses recent World Bank data on Internet usage to examine whether the Internet has had any effect on the relationship between government regulations and firm entry rates across 78 countries. The primary results show that Internet usage does not appear to have a significant effect on this relationship, but the results from a robustness check between high and low income countries suggest that in high-income countries, the Internet actually increases the burden of one of the main regulations; the cost to register a business.

College students and emerging adults have been found to be at risk for smoking cigarettes, drinking to excess, using illicit drugs, driving dangerously, and engaging in risky sexual and delinquent behaviour. Psychosocial correlates (Sensation Seeking, peer behaviour, parent behaviour, and peer and parent anti-substance use messages) from three domains of influence (personality, parent, and peer) were examined together to provide a greater context for the occurrence of such health-risk behaviours. The strongest predictor(s) of each behaviour were identified to better inform intervention practices. Three groups were compared— 1) those who never tried substances, 2) those who tried substances in the past, and 3) those who continue to use substances at present, in a population of emerging adults. Self-report data was gathered from 203 Collèges d'Enseignement Général Et Professionnel (CEGEP) students in the Montreal region. Measures included: Reckless Behaviour Questionnaire, Reckless Driving Measure, Health Behaviour Survey, Sensation Seeking Scale—Form V, and the Marlowe-Crowne Social Desirability Scale. Results revealed that peer behaviour was the most significant predictor of substance use in emerging adults, whereas parent behaviour was only a significant predictor of reckless driving. Sensation Seeking, specifically Disinhibition, was found to predict more global reckless behaviours, including illegal activities, such as stealing or using marijuana (p < .01). Neither peer nor parent anti-substance messages were significantly related to any of the health-risk behaviours measured in this study. It would appear that health-risk behaviours tend to be related to the same underlying factors but to varying degrees. Intervention implications are discussed.

De nouveaux produits et services jouissent aujourd'hui d'un succès surprenant, alors qu'ils ne s'intègrent pas dans les canons traditionnels de l'innovation. Sans proposer de ruptures technologiques ni d'usages clairement identifiés, ces biens suscitent toutefois une large exploration d'usages nouveaux et inconnus, à l'image du service web Twitter ou du téléphone iPhone qui viennent bouleverser les pratiques quotidiennes de leurs usagers dans de nombreux domaines, y compris professionnels.La littérature apporte des réponses partielles aux enjeux soulevés par cette classe de biens, mais semble limitée par une vision des biens comme systèmes de découplages de la conception d'usages : celle-ci aurait lieu au sein de la firme par des approches de type analyse d'usage ou bien auprès d'usagers-concepteurs très compétents.Nous proposons ici une théorie qui veut intégrer ces différents apports tout en soulevant les hypothèses que nous jugeons trop restrictives sur les usagers, les biens et leurs rapports à la conception d'usage. Ce projet nous amène à rediscuter la notion de biens pour les considérer comme des espaces de conception d'usages, à destination d'acteurs à la fois usagers et concepteurs.Ce nouveau paradigme suppose en revanche de réinterroger le rôle de la firme dans l'organisation de cette action collective de conception d'usages. La confrontation de notre modèle théorique à trois études de cas révèle que les succès que l'on connait aujourd'hui reposent sur une organisation sophistiquée des relations entre la firme et ses usagers concepteurs, ainsi qu'une ingénierie spécifique de dispositifs de conception, de formation et de coordination.

Achieving sustainable consumption of energy is an important issue due to the increasing demand for energy and its environmental impact. One of the biggest consumers of the global energy production is the residential sector. Factors determining pattern of energy consumption in this sector are firstly, characteristics of the buildings and equipment and appliances which are used inside them and secondly, people who are using the buildings. The former could be approached by using efficiency strategies; i.e. designing and using materials and utilities which are low energy demanding or reducing consumption of energy. The latter could be reached by adoption of demand side management strategies which could improve pattern of energy consumption by the end users. Combining these strategies bring out energy-smart buildings with energy-smart people as the users. This project aims at introducing potential approaches to strategies of promoting sustainable behavior regarding energy consumption in individuals, with the focus on the students of Linköping University living in the properties of housing company of the city, Studentbostäder. For fulfilling this purpose, literature review has been done for finding influencing factors on and strategies for shaping of pro-environmental behavior. In the next step, two projects with focus on demand side management for changing energy consumption of individuals have been studied. Afterward, a questionnaire based on the results of the literature review was prepared and used to gain an understanding of first: attitude, values, knowledge, and awareness of students of Linköping University regarding environmental issues, and second: point of view of the students toward the strategies for shaping pro-environmental behavior. Results of the above mentioned methods were used for identifying characteristics of a demand side management project based on provision of feedback on energy consumption for the users. It has been proposed that designing and implementing such project has the potential of affecting pattern of energy consumption by people and lead to its reduction, especially among students accommodating at housing company of city of Linköping, Studentbostäder. More studies are needed for finding feasibility of implementing such project.

Lugha inaweza kutumiwa kwa njia ya ubunifu wenye ufasaha ufaao ili kuwasiliana au pia ikatumiwa visivyo na kwa njia potovu. Ni nini hasa maana ya kutumia lugha kwa njia potovu? Pengine ni rahisi kueleza kinyume chake. Mtumiaji wa lugha mwenye ubunifu huzingatia rasimali zote za lugha. Mwandishi maarufu wa fasihi barani Afrika, Chinua Achebe, huitumia lugha kama kituo kilicho hai na pia kuendelea. Katika juhudi za kuifanya lugha kumwezesha kutoa maoni, maelekezo, habari na hisia, mtumiaji kama huyu hutambua kuwa lugha ikitumiwa ipasavyo huleta uhai katika taaluma ya mawasiliano. (Luvai, 1991: 60) Hata hivyo, katika Kenya, kiwango che ubora wa uandishi kwa jumla kimeshuka sana katika miaka ishirini iliyopita. Makala hii itachunguza kwa muhtasari ushahidi wa matumizi yasiyofaa ya lugha ya Kiswahili katika vyombo vya habari km. redio, televisheni na magazeti.
