L’objectif principal de cette thèse est d’estimer la valeur d’utilité de l’immobilier des entreprises en examinant cet actif aux travers de différents prismes. Nous avons tout d’abord étudié les principales théories macroéconomiques qui régissent la gestion des portefeuilles diversifiés d’actifs, puis mesuré les effets de l’immobilier de l’entreprise sur la perception du couple rentabilité/risque de différents secteurs industriels par l’analyses graphiques et des mesures de corrélation. Nous nous sommes intéressés à deux entreprises représentatives d’industries présentant des singularités fortes : le groupe Casino, que nous avons associé à sa foncière Mercialys, et le groupe Accor. L’étude de ces structures a permis de mettre en lumière des stratégies et des comportements différenciés essentiellement centrés sur la problématique du couple rentabilité/risque. Nous avons souhaité vérifier par la suite les hypothèses émises lors de l’étude de ces deux groupes en nous replaçant dans la perspective plus générale des acteurs et en testant in vivo la perception de la valeur d’utilité de l’immobilier des entreprises. Nous avons pour cela orienté cette recherche vers une approche empirique basée sur une enquête. Nous avons ainsi validé le fait que l’immobilier est essentiellement perçu par les acteurs comme un outil de la gestion du couple rentabilité/risque de la société (et particulièrement de la dette) avec, cependant, des composantes associées plus ou moins affirmés selon le paradigme, les finalités et la perception de la classe d’acteurs qui le considérait. La situation de l’entreprise pouvait de même faire évoluer la nature de cette valeur pour les répondants avec pour objectif systématique la maximisation de leur bien-être. Enfin, nous avons précisé dès le début de cette recherche que cette dernière était marquée par sa temporalité et qu’elle devra être mise à jour dans dix ans à la lumière de données statistiques plus significative sur la durée. / The principal objective of this study is to estimate the utility value of a company’s Real Estate by analysing this asset utilising different methods. In the beginning, we studied the principal theories of macroeconomics which lead to the creation of a diverse portefolio of assets. We then measured the impact of the company’s real estate value on the perception of the profitability/risk ratio within different industrial sectors. To achieve this, we used a graphic analysis tool and we measured the level of correlation between different indexes. We have examined in detail two representative companies of specific indexes which demonstrated strong and unusual strengths: the Casino Group, that we have linked to its Real Estate investment trust Mercialys and the Accor Group. The study of these businesses has allowed us to demonstrate unique strategies and adaptive behaviors based on the optimization of the profitability/risk ratio. We wanted to verify thereafter the specific hypotheses created during the study of these two companies. For that, we adopted a more general approach and we tested in vivo the perception of the utility value of a company’s Real Estate. We oriented the research to an empirical approach based on the survey data. We validated the fact that Real Estate is essentially considered by the people involved in this industry as a tool for managing the profitability/risk ratio of a company (and particularly the level of the debt) with more or less significant additional components according to the paradigm, the objectives and the personal perception of each group within each segment. The current situation of the company could significantly change the perception of the nature of its value for a specific group with the systematic objective of maximizing their position. We specified when we started this research project that this work is relevant to the date it was produced and it has to be updated in ten years with more significant temporal data.

This study tested a self-generated utility value intervention aimed at increasing undergraduate statistics students’ motivation and achievement. The intervention was based on Situated Expectancy-Value Theory (Eccles & Wigfield, 2020) and encouraged students to make relevant connections between statistics learning content and their lives, primarily emphasising the content’s usefulness to the student, or utility value. In testing a self-generated utility value intervention within the domain of undergraduate statistics, the study extended research previously conducted in high school and undergraduate sciences (psychology and biology) and replicated Hulleman et al. (2017) which tested the role of frequency of students’ connections between the learning content and their lives in their motivation and achievement. In addition to transferring a self-generated utility value intervention to the domain of statistics, the study’s main contribution was made by investigating the role of connection quality—the quality of utility value connections undergraduate statistics students made between the learning content and their lives in their motivation and achievement. The study used collected data from a blindly randomised longitudinal field experiment conducted with undergraduate business school students from a research-intensive university located in the north-eastern USA. The students were of two differing sections of the same 15-week introductory statistics course. The self-generated utility value intervention consisted of prompts, twice during the semester, which instructed stud¬¬ents to write 2-3 paragraphs in response to. Data collected was comprised of students’ gender, first-generation status, initial/final achievement assessments, pre/post self-reports on motivation (expectancy, cost, intrinsic value, utility value) and connection frequency, and researcher scaled ratings coding on student intervention responses for connection quality. Part I Results from this study suggest that the intervention significantly increased students’ achievement (d = .42)—an approximately 7-percentage point difference between intervention and control group conditions. Furthermore, the intervention was found to be especially effective at increasing at-risk, low initial achievement, students’ motivation (expectancy, d = .54) and achievement (d = .87)—an approximately 14.5-percentage point difference between group conditions. Study results also suggest that the intervention’s impact on at-risk students’ achievement was mediated via motivation increases—through students’ expectancy for success, though, not through students’ utility value. The Part I results were confirmatory of Hulleman et al.’s (2017) findings—the intervention effected students’ achievement, but the pathway of indirect effects traversed through students’ expectancy, not their utility value which Hulleman et al. (2017) and this study both hypothesised it would do instead. Part II Results attempted to explain the intervention’s pathways of effects through expectancy to achievement by creating new measures, connection quality measures. Connection quality measures were constructed to capture students’ utility value more effectively than the self-reported utility value survey measure. This study’s Part II Results suggest that the intervention was found, again, to significantly increase students’ achievement (d = 1.46), but the indirect intervention effects traversed a pathway to affecting students’ achievement, not through their expectancy, but through their utility value (as captured via the newly minted connection quality measures), to their motivation (cost and interest), and then to their achievement. The new connection quality measures, exploratorily, were found to capture students’ utility value more effectively than the self-reported utility value survey measure, enabling the self-generated utility value intervention’s effects on students’ achievement and motivation to be further explained. / Math & Science Education

Cette étude avait pour but de vérifier l’incidence de la relation maître-élève sur la motivation des élèves particulièrement en milieux défavorisés. Notre hypothèse stipulait que meilleure est la relation maître-élève, plus grande est la motivation de l’élève. Nos objectifs étaient d’analyser la valeur prédictive de la relation maître-élève sur les déterminants de la motivation scolaire afin d’identifier quels aspects de la relation maître-élève, dans une perspective d’attachement (chaleur, soutien ou conflit), prédisent le mieux chacune des variables motivationnelles retenues. Aussi, nous voulions identifier quelles variables motivationnelles sont les plus affectées par la qualité de la relation maître-élève. La motivation scolaire a été évaluée à deux niveaux soit général et spécifique au français et aux mathématiques. Certains des déterminants retenus sont en lien avec les modèles Attentes-Valeur (le sentiment de compétence, l’intérêt et la perception de l’utilité de l’école en général ainsi qu’en français et en mathématiques). Les autres déterminants retenus sont en lien avec la théorie des buts d’accomplissement (le but de maîtrise, le but de performance et le but d’évitement du travail). Nous avons aussi vérifié l’effet modérateur du sexe dans les relations entre les variables d’attachement et la motivation. Nos résultats montrent que la relation maître-élève prédit avec assurance l’intérêt général envers l’école, l’intérêt spécifique au français et aux mathématiques ainsi que la présence de buts d’évitement du travail. Nous avons aussi été en mesure de déterminer qu’une relation soutenante serait l’aspect de la relation maître-élève qui prédirait la présence du plus grand nombre de déterminants de la motivation scolaire. Il a aussi été surprenant de constater l’effet de la relation chaleureuse sur les trois dimensions en lien avec l’intérêt (général, en français et en mathématiques). De son côté, l’intérêt général fut aussi remarqué comme étant le déterminant motivationnel étant le mieux prédit par la relation maître-élève. Nous avons aussi fait ressortir que la perception de conflit serait l’aspect de la relation maître-élève qui présenterait la plus grande valeur prédictive de certains déterminants de la motivation. Par contre, nos résultats ne permettent pas de supporter que le sexe de l’élève a un effet modérateur dans les relations. / The objective of this research was to assess the impact of the teacher-student relationship on students’ motivation, particularly within low income families. The study conducted was based on the hypothesis that better teacher-student relationship lead to a higher level of motivation for the student. In order to verify this hypothesis, our objectives were to analyse the predictive value of the teacher-student relationship on school motivational determinants in order to identify which aspects of teacher-student relationship, in an attachment perspective (caring, supportive or conflictive), could better predict each of the motivational variables. Also, we wanted to identify which of these motivational variables are most affected by the quality of the teacher-student relationship. Some of the determinants come from Expectancy-Value models (perceived competence, interest, perceived utility of school in general, and for French and Mathematics). Other determinants come from goal orientation theory (mastery goal, performance goal and work avoidance goal). We also verified the moderator effect of gender in the attachment variables and the motivation. Our results show that the student-teacher relationship can predict interest in schooling in general, specific interest in French and Mathematics, and the presence of avoidance goal. We also showed that a supporting relationship could be the aspect of teacher-student relationship which mostly predicts the motivational variables. It was also surprising to see the impact of a caring relationship on the three dimensions of interest (general and subject related). Interest in general was also the motivational variable best predicted by the teacher-student relationship. We also showed that the perception of conflict is the aspect of the teacher-student relationship which could best predict some of the motivational determinants. However, our results could not support the moderator effect of gender on the relationship.

En la actualidad, podemos observar que el comportamiento de compra del consumidor se inclina cada vez más al canal online, el cual es un medio importante para el crecimiento de las empresas. En función a este contexto, hemos considerado oportuno realizar nuestra investigación sobre los distintos factores motivacionales que influyen de manera directa en la intención de compra online y con esto reconocer cuál es el más determinante. Para ello, se han desarrollado las siguientes variables de estudio, tales como: valor utilitario, valor hedónico, confianza, conveniencia y privacidad. Para nuestra investigación hemos propuesto realizar un estudio cuantitativo, ya que debido al contexto en el que nos encontramos, no podremos realizar focus group, expediciones de campo ni otra actividad que implique alguna relación social. / At present, we can observe that shopping purchasing behavior consumer is increasingly inclined to the online channel, which is an important means for the growth of companies. In this context, we have considered it appropriate to carry out our research on the different motivational factors that directly influence online purchase intention and thereby recognize which is the most decisive. For this, the following study variables have been developed, such as: utility value, hedonic value, trust, convenience and privacy. For our research we have proposed to carry out a quantitative study, because we will not be able to carry out focus groups, field expeditions or any other activity that implies any social relationship. / Trabajo de investigación

<p dir="ltr">Scientific writing is a core competency within the undergraduate biology curriculum (AAAS, 2010), as it has wide-ranging applications in academic and professional life, alongside being a powerful tool for formative learning (Wingate, 2010). Due to its importance in critical analysis and understanding of biological concepts, developing scientific writing is necessary for success within the biological sciences disciplines (Clemmons et al., 2020). Peer review has emerged as a common pedagogical technique to address the need for scientific writing training. The expansive literature on peer review indicates its ability to engage students in critical thinking, increase writing confidence, and improve academic performance on writing assignments (Dochy et al., 1999; S. Gielen et al., 2010; van Zundert et al., 2010). Research on the usage of scaffolded curriculum within peer review has shown increased review validity from students (Cho et al., 2006; Liu & Li, 2014), and integrated plans to revise leads to increased revisions (Wu & Schunn, 2021) and the incorporation of more feedback that is correct (Jurkowski, 2018). However, despite the breadth of peer review research, the number of quasi-experimental and experimental studies assessing the benefits and perceptions of revision is small (Double et al., 2020; van Zundert et al., 2010). This study provides a detailed look at the effects of scaffolded peer review and structured revision on student perceptions of scientific writing self-efficacy and the utility value of the peer review process. After performing peer review, students were given either a supported revision worksheet, wherein students list the feedback received and if it is useful for revisions, or a general revision worksheet, where students list their planned revisions. Quantitative surveys and qualitative reflection questions were administered to gauge the scientific writing ability and the perceived usefulness of peer review and were compared between treatment groups. Little to no difference was found in how students perceived their scientific writing self-efficacy and the utility value of the peer review process. Despite the lack of differences, analysis of the themes within responses reveals alignment with the theoretical frameworks guiding this research. This study provides a rich account of the characteristics of scientific writing self-efficacy and utility value in undergraduate biology students during peer review and revision, which have implications for the future development of an effective scaffolded peer review curriculum.</p>

<p dir="ltr">Accurately assessing outcomes of students’ motivation when solving complex food system problems through integrating STEM learning can describe their learning experiences and help teachers make relevant connections. This study shows high school students self-reported that they were motivated by solving food system STEM projects.</p><p dir="ltr">The purpose of the study was to predict high school students’ self-efficacy (confirmed by Exploratory Factor Analysis, EFA) based on Situated Expectancy-Value Theory (SEVT) variables (confirmed by EFA). The convenience sample for this study was students from four high schools in Indiana (<i>N</i> = 160) who had participated in food system STEM projects at their schools. Quantitative data was collected using the Food System Motivation Questionnaire containing 41 items related to two self-efficacy variables and five SEVT variables. Quantitative data were analyzed using Principal Components Analysis, descriptive statistics, simple linear correlations, and multiple regression. Qualitative data were collected using a focus group interview protocol (Appendix D) and analyzed using thematic coding (deductive) followed by pattern coding. Quantitative and qualitative findings were analyzed using triangulation.</p><p dir="ltr">There were four conclusions to this study. First, the Food System Motivation Questionnaire accurately and reliably measured five variables aligned with SEVT motivation.
