Modéliser l'insertion territoriale du Miscanthus x giganteus à partir des décisions des agriculteurs : une approche exploitant le modèle du raisonnement à partir de cas / Modelling miscanthus allocation in farmland based on farmers’ decisions : a framework using the case-based reasoning model

Martin, Laura 01 December 2014 (has links)
Le Miscanthus x giganteus est une culture pérenne, nouvellement produite en Europe et présentant un intérêt fort pour son usage énergétique. Son implantation présage donc une réorganisation territoriale pérenne. Pour anticiper cette réorganisation, de nombreuses études modélisent les dynamiques spatialement explicites de son insertion. Notre thèse se positionne dans ce courant de recherche. Celle-ci vise à proposer un nouveau cadre de modélisation des processus de décision des agriculteurs, permettant la dissémination horizontale (scaling out) de ces processus issus d’études de cas, vers des territoires élargis. Pour cela, la thèse exploite le modèle du raisonnement à partir de cas. Elle articule (i) une démarche d’acquisition de connaissances sur les processus de décision des agriculteurs relatifs à l’insertion territoriale du miscanthus et (ii) la conception et évaluation d’un prototype ad hoc de raisonnement à partir de cas. La phase d’acquisition des connaissances montre que le processus d’insertion territoriale du miscanthus est complexe : celui-ci est étroitement lié aux contraintes parcellaires du territoire. Ces connaissances nous conduisent alors à discuter du choix des variables biophysiques et humaines intégrées à ce jour dans les modèles spatialement explicites. La phase de conception et d’évaluation du prototype de raisonnement à partir de cas montre que le modèle du raisonnement à partir de cas est particulièrement bien adapté pour modéliser un phénomène contextualisé. Evalués sur nos données d’enquêtes, ces résultats nous conduisent à discuter des modalités d’application du prototype sur d’autres bassins de production de miscanthus / Miscanthus x giganteus is the perennial crop, newly produced in Europe. Even if miscanthus is not so heavily produced nowadays, this crop would be of great interest for energy use. However, the allocation of miscanthus could produce a sustainable reorganization of the landscape. Therefore, many studies aim to model the land use change caused by miscanthus, in order to identify sustainable supply areas: our research belongs to this field. In our research, we propose a new framework for modeling decision-making process of farmers, relying on scaling out. More accurately, we propose to use the case-based reasoning model which solves problems based on an analogical reasoning. Then our research is structured: (i) by a knowledge acquisition step about decision-making process of farmers, based on farm surveys, conducted in the Côte d'Or department (Burgundy region) and (ii) by the design and evaluation of an ad hoc prototype of case-based reasoning. On the one hand, results of knowledge acquisition phase show that miscanthus allocation process is complex, more accurately, that miscanthus allocation process is closely related to land constraints, particularly in terms of logistic and environmental preservation of plots. These results lead us to discuss the selection of biophysical and human variables included to the current spatially explicit models. On the other hand, the design and evaluation phase of our prototype shows that case-based reasoning is particularly well suited to model a contextual phenomenon. These results lead us to discuss the modalities for implementing the prototype in other production areas of miscanthus

Business Intelligence – its impact on the decision-making process at higher education institutions : A case study at Karlstad University / Business Intelligence – dess påverkan på beslutsprocessen vid högskolor : En fallstudie på Karlstads Universitet

Persson, Jacob, Sjöö, Erik January 2017 (has links)
The purpose of this thesis is to understand how Business Intelligence (BI) influences the decision-making process (DMP) at higher education institutions (HEIs). Furthermore, this study aims to identify success factors of BI adoption (gathered from previous research) that are difficult for HEIs to fulfill. The study applied a qualitative research strategy and was conducted as a single case study at Karlstad University (KaU), a Swedish public HEI with approximately 16 000 enrolled undergraduate students and 1 200 employees. Regarding the data collection process, empirical data was collected through eight semi-structured interviews, all held with users of KaU’s BI tool. The thesis’ findings show that BI affects the DMP at HEIs by increasing the quality of information, reducing time, and increasing the efficiency for the user. The findings also show that for a HEI, most key components that increase an organization’s chance of a successful BI implementation are difficult to fulfill completely. Three components were identified to be in greater need of improvement than the rest: management & leadership commitment, culture around use of information and analytics, and requisite resources. / Syftet med denna studie är att förstå hur Business Intelligence (BI) påverkar beslutsprocessen vid högskolor. Vidare, strävar denna studie efter att identifiera framgångsfaktorer för BI-implementering (samlade från tidigare forskning) som är svåra för högskolor att uppfylla. Studien tillämpade en kvalitativ forskningsstrategi och genomfördes som en fallstudie vid Karlstads Universitet (KaU), ett svenskt statligt universitet med ungefär 16 000 studenter och 1 200 anställda. När det gäller datainsamlingsprocessen, samlades empirisk data in genom åtta semi-strukturerade intervjuer med användare av KaU:s BI-verktyg. Studiens resultat visar att BI påverkar beslutsprocessen vid högskolor genom att öka kvaliteten på information, reducera tidsåtgången och öka effektiviteten för användare. Resultatet visar också att för en högskola är det svårt att uppfylla helt och hållet de faktorer som ökar chansen för en lyckad BI-implementation. Tre områden identifierades att vara i större behov av förbättringar än de övriga: chefs- och ledarskapsengagemang, kultur kring användning av information- och analysverktyg samt nödvändiga resurser.

Rodí se během krize více dětí? Příklad Spojených států amerických / Are more children being born during economic recessions? The example of the United States of America

Mihalko, Jan January 2013 (has links)
The thesis focuses on the issue of individuals' preferences regarding the acquisition of a child during the business cycle expressed in unemployment rates for men and women. Fixed effects model involving robust estimates of standard deviations on a panel dataset tested for the period 1980-2012 confirmed the significance of the relationship between sex-specific unemployment rates and fertility rate of the United States of America. The results of the analysis show a negative relationship documenting pro-cyclical nature of the fertility. There is a less willingness of couples to conceive a child with the growth in unemployment. It does not show the prevalence of substitution effect of reducing opprtunity costs for women during the recession over the effect of reduction in income. Among other statistically significant variables that affect fertility belong the degree of attainment of university education, the poverty rate and abortion rate.

Rozhodovací proces rodičů o odkladu povinné školní docházky / Decision - making process of parents in the field of postponing the compulsory school attendance

Svobodová, Zuzana January 2016 (has links)
This dissertation describes the decision-making process of parents in the field of postponing the compulsory school attendance or starting it on schedule. The qualitative research is based on an aggregate of 41 semi-structured interviews with parents and two focus groups, completed by subsequent observations and interviews with parents and teachers. The research goal consisted in illuminating the background of the high number of postponements in the Czech Republic, where every year about 20 % of children start in the first class a year later. The dissertation also provides insight on this topic in a comparative perspective and analyzes the initiation of compulsory education in selected European countries. The research results presented in the form of an established theory document that parents' decisions are based primarily on the needs of the family and especially of the need to be a good parent. The decision making is influenced also by the parents' attitude to the delay which has also impact on the weight being attached to other factors of the decision-making process, such as school maturity and individual areas of school readiness as well as the month of birth. During the decision-making process the experience of parents with enrolment in the first grade plays an important role as well. The...

Názoroví vůdci v řadách současných českých novinářů / Opinion Leaders Among Czech 21st Century Journalists

Kolomazníková, Eliška January 2020 (has links)
The objective of this master's thesis is to examine the concept of opinion leadership-to define it, to describe where it originated from, how it has developed over time, and finally, to apply this phenomenon to the Czech journalist community and its current members. Based on relevant international literature, the author of this paper assumes that opinion leaders exist in every social group or community around the globe, possessing an extraordinary personal influence on the decision-making and opinion-forming process of the people within their social network. Simply put, opinion leaders are the individuals to whom others look for guidance, credible and accurate information and context when they are in doubt or experiencing indecisiveness. For journalists, the possibility to have someone to whom they can turn for all the above-mentioned is crucial, the author believes, for it is a daily part of the profession to handle information cautiously, to evaluate news critically and objectively, and to get acquainted with a confusing topic in a relatively short period of time. Firstly, the paper offers a thorough theoretical framework for understanding the concept of opinion leadership, which is followed by a practical part consisting of a two-phase research examining opinion leaders in the ranks of Czech...
