The effects of hydrocolloids (Hydroxypropylmethylcellulose (HPMC), Carboxymethylcellulose (CMC), Xanthan gum (XG), and Apple pectin (AP)) at different concentrations on dough thermo-mechanical properties and in vitro starch digestibility of gluten-free potato steamed bread were investigated. Results showed that hydrocolloids addition significantly increased the gelatinization temperature (from 52.0 to 64.2 °C) and water absorption (from 56.22 to 66.50 %) of potato dough. Moreover, hydrocolloids may be interacted with protein and starch, the density of potato protein bands was decreased by hydrocolloids addition, the reason might be that higher molecular weight complexes might be formed between proteins-hydrocolloids or proteins-proteins, thus change the protein solubility. Furthermore, steamed breads with hydrocolloids presented higher specific volume and lower hardness, and the rapidly digestible starch and estimated glycemic index were significantly decreased from 45.51 to 20.64, from 69.54 to 55.17, respectively. In conclusion, HPMC and XG could be used as improvers in the gluten-free potato steamed bread. [less ▲]

To look at energy consumption through a different lens, we have developed the conceptual framework of habitual practices. The objective of the present paper is to propose an empirical application of this framework, with the aim of unravelling the constitutive ‘ingredients’ of energy-consuming practices. Therefore, we investigate whether discussing the relationship of people with their homes could help circumventing the methodological difficulties that inevitably arise when trying to approach less tangible (albeit crucial) elements such as norms and attached meanings. The empirical material comes from group conversations where participants discussed the extent to which a home has to be practical, comfortable and convivial in connection with a series of elements. The results confirm that this methodological setting generated useful insights for a finer understanding of energy-consuming practices and their underlying drivers. A related crucial finding is the role of key appliances – those with more contrasted use and attached meanings – which appear to mediate the interplay between comfort, conviviality, and practicality. A promising avenue for future research would thus be to further investigate the role of those key appliances as potential markers of wider tendencies in energy consumption and useful for designing segmentation strategies.

This thesis is dedicated to studying the Protoromance suffix */-'ur-a/ and, hence, to studying derivational morphology of Protoromance. On the one hand, we provide an extensive and detailed exam of Protoromance lexical units presenting the suffix */-'ur-a/ and, on the other hand, we produce a thorough analysis of the phonological, morphological and semantic properties of the suffix */-'ur-a/. The first part of this work consists of a short introduction and of the presentation of the methodology that we used in our research : the methodology of compared reconstruction and of internal reconstruction. Then, we focus on the two fields that are particularly interesting in the context of studying a Protoromance suffix : reconstruction in Romance studies and morphological reconstruction. This first part closes up with an explanation of our nomenclature – including a short analysis of the rejected words –, a specification of our research process and a presentation of the microstructure used for our etymological articles. In the second part of our thesis appear the etymological articles of all 45 Protoromance etymons with the suffix */-'ur-a/ that we were able to reconstruct. Each etymological article comes with a linguistic map that provides a global view of the geographical distribution of the concerned etymon. Finally, the third part of our work is a thorough and detailed analysis of the phonological, morphological and semantic properties of the Protoromance suffix */-'ur-a/ and of the diasystemic variation of the Protoromance language.

In spite of core medical advances realized these last years, the childhood cancer remains a distressing experience for the child and their parents. The cancer history is rarely linear and takes place into a space and a particular time when marks are shaken. The stake in paediatric oncology is double: that the child is cured without side effects and that the child and parents cross this experience without psychological destabilization. When the cancer survivorship is diagnosed, new challenges are expecting for the child and parents. Indeed, the childhood cancer survivorship is considered as integrated into the field of chronic diseases where the factor of uncertainty coexists and requires continuous adjustments of the child and parents. Therefore, it is a period of progressive rehabilitation where the stake is double: control the relapse and treatments’ late effects (or aftereffects) of the child and allow the child and parents, “to pursue their life the most normally possible”. The survivorship experience is thus intense transforming deeply “the psyche” of the child and parents. Since a few years, empirical studies examine the child adjustment and parents in the course of treatments. These reveal namely some adaptation difficulties, anxious and depressive symptoms. However, the social/family support and the problem-focused coping seem positively moderate the distress intensity. Studies investigated the cancer survivorship were mainly centred on the child and showed its effects on the child’s psychological adjustment (e.g. anxiety, depression). Nevertheless, the distress intensity could be positively influenced in particular by social and family support factors. The thorough examination of the literature observes that studies rarely include the parent and that no study has associated the factor of uncertainty with the vulnerability factor of intolerance of uncertainty. The originality of this research lives in the interest centred on the concept of intolerance of uncertainty [IU] and its effects on the psychological and cognitive adjustment among parents of a child cancer survivor. This quasi-experimental, quantitative, longitudinal research combines standardized questionnaires (IUS, NPOQ, CAQ, Mini-CERTS, HADS, and WW-II), questionnaires created for the needs of the study (sociodemographic, QIPS-R15, OncoMed and SomaOnco) and two neuropsychological tasks (classic Stroop and emotional Stroop). The sample consists of 61 parents (45 mothers and 16 fathers) of a child cancer survivor (from 4 to 6 years of survivorship without relapse and with mainly a neoadjuvant chemotherapy during treatments). Three months later, parents returned to the laboratory and completed the same questionnaires and performed Stroop tasks (with the exception of words which are modified). The time was decided with medical teams. It seemed relevant to retest parents when the medical assessment of the child was completed in order to observe if the distress decreased. Besides, this time was sufficient to avoid memory biases. The first aim of this research is the study of parental distress. The proposed hypothesis is the existence of anxious, depressive, somatic symptoms and worries. Results showed that 70 % of parents had anxious symptoms (HADS), 39 % presented depressive symptoms (HADS), 14 % suffered from somatic symptoms (SomaOnco) and 70 % had worries (QIPS-R15). Results from moderation analyses indicated no main effect of gender, remission time, and couple on distress criteria (except the interaction of these three factors for worries). These results demonstrated the existence of a significant distress within the sample but also the presence of additional factors which may influence the parental adjustment. The second aim is the examination of IU and its maintaining factors (i.e. positive beliefs about worry, cognitive avoidance, negative attitude towards problems and repetitive thinking (ruminations)). The advanced hypothesis is the causal track between IU and its maintaining factors. Results of IUS questionnaire demonstrated on average that parents had a low tolerance of uncertainty (64 % of the sample) and that 60 % of the sample were located in a moderated to severe profile of generalized anxiety disorder (GAD). Concerning IU’s maintaining factors, results of NPOQ, CAQ, WW-II and Mini-CERTS questionnaires highlighted the existence of positive beliefs towards worry (WW-II: problem solving and positive trait of personality) and cognitive avoidance (CAQ: distraction and thought suppression). Results of regressions bear out the predictor status of IU for the development of its maintaining factors. Nevertheless, protective factors arose from analyses, particularly an effective problem orientation and the use of concrete experiential thinking mode (CET; Mini-CERTS), which could protect them from a deterioration of the mood (e.g. depression). These results indicated the negative influence of IU on the psychological adjustment, the protective effect of a positive attitude orientation and the use of CET among parents. The third aim concerns the study of cognitive processes in terms of orientation of selective attention and cognitive inhibition. The proposed hypothesis is the orientation of selective attention towards threat into the IU context. Results seem to indicate a longer latency for negative and coloured words during Stroop tasks. The within-group regression and mediation results reveal the mediating effect of IU between the orientation of selective attention towards threat and distress components (i.e. anxious, depressive, somatic symptoms and worries). Moreover, depressive symptoms contribute to predicting the coloured word latency (cognitive inhibition process). These results seem to demonstrate the negative influence of the IU on the orientation of selective attention and depressive symptoms for cognitive inhibition. Lastly, the fourth aim is the analysis of IU stability and its maintaining factors over time. The proposed hypothesis is the stability of IU and its maintaining factors because IU is considered as a feature of the personality. At the second assessment (n=51/N=61), three significant differences were observed. The first difference concerns a decrease for anxiety symptoms with nevertheless a score being located in the pathological border. The second difference relates to a decrease for the cognitive avoidance with a score situated in the superior border of the standards. Lastly, an increase for somatic symptoms level was observed at the second assessment. Concerning IU, results indicate no significant change. Parents who presented a high level of IU at the first assessment kept it at the second assessment. This observation is also true for parents who had a low level of IU. These results supported the hypothesis of IU stability and its maintaining factors over time. Overall, results emphasize the implication of IU in the psychological distress among parents and its effect on cognitive processes of the orientation of selective attention towards threatening words (negative words). This research brings out the necessity to identify parents who are at risk for IU (and its maintaining factors) at an early stage of the cancer management in order to avoid excessive worries and the use of dysfunctional strategies over time. Furthermore, this research allows future clinical avenues for the development of follow-up tools in paediatric oncology, and recommends the parents’ psychological adjustment follow-up in close collaboration with medical teams. Implications of this research are discussed into the "general discussion" part of the thesis. [less ▲]

The governance of urban regions is a central research topic of urban sciences, and a major challenge for urban actors. In this research, we contribute to the analysis of governance processes by studying the transformation of its spatiality in intermediate European urban regions. Our research postulates the intrinsically spatial nature of urban governance, and is based on three hypotheses: (1) the territorial characteristics of urban regions relate to local politico-administrative fragmentation, (2) the characteristics of politico-administrative fragmentation relate to the construction of a governance scale for urban regions, and (3) governance structures at the level of urban regions relate to territorial characteristics. In order to test these hypotheses, we conducted a research in three complementary parts. The first part is devolted to the state of the art on governance, territorial rescaling and institutional change. The second part analyses quantitatively the politico-administrative fragmentation of 123 intermediate European urban regions, and its links with territorial indicators. The third part analyses qualitatively the processes of transformation of spatial governance in the urban regions of Saint-Étienne (France), Metz (France), Sheffield (United Kingdom) and Liège (Belgium). This complementary research confirms the existence of links between the different aspects of spatiality in the governance of intermediate urban regions in Europe, and concludes that the recomposition processes are intrinsically spatial, territorial and multiscalar.

Teaching translation is a very old activity. While it often used to be performed in the context of language learning, it has changed fundamentally over the past few decades, i.e. since the institutionalization of translation as an autonomous scientific discipline with specific objects and methods. Now, it covers not only linguistics but also other fields including the operating aspect of knowledge and has undergone more methodological transformations over half a century than it did since the Middle-Age, or even since Cicero. In Niger, however, the situation has not yet changed. Teaching translation has remained part of language learning. In this context, the learners’ translation competence is directly associated to linguistic competence. But the latter is far from satisfactory for quite a lot of Niger students, whatever their field of study. In fact, several studies confirmed the poor performance of Niger students in relation to mastery of their working language, French. Indeed, despite its exclusive status as the language of administration and education, French is not mastered enough to be used as a basis for the learning of another language and even less for translation purposes. This is why this study is based on the hypothesis according to which improving the target language in translator training would largely contribute to upgrade their translation competence. It therefore aims to enhance Niger prospective translators’ translation competence by improving their knowledge of the working language. To this end, an experimental research method is used that relies on a classical type scheme involving pre- and post-experimentation observations. An experimental treatment is applied between the two observation stages, which consists of language remedial courses. The verification of the hypothesis depends on operational aspects of the study as well as on the results yielded by the interpreting of collected data. [less ▲]

Usually, a set of Traceroute measurements collected for a large amount of target IPs contain one or several route hops at which the IP interfaces vary from one measurement to another. These variations occur even if several measurements share the same length and the same last hops. This is likely a consequence of load balancing, a traffic engineering policy which aims at sharing the load to ensure quality of service. In this paper, we consider the problem of conducting alias resolution on IP interfaces discovered via Traceroute and which are involved in load balancing. By conducting alias resolution in such a context, we want to verify if the IP interfaces involved in load balancing belong to unique routers, and more broadly, how relevant is alias resolution in this context. To do so, we use a slightly edited version of TreeNET, a topology discovery tool which relies on a tree-like structure based on Traceroute measurements to map a target domain. The upgraded TreeNET along the measurements described in this paper are both freely available online. [less ▲]
