The review of the existing frustration theories resulted on a model which allowed the evaluation of 'social perception' interference upon the reaction to frustration we examined three of the possible theoretic91 explanations to determine the differences of perception of the 'locus of control': the first one was examined in terms of the learning theory the second one, in terms of character organization and the third one in terms of temperament factors. We also presented a review of the experimental attempts and confirmations concerning the construct 'locus of control' and the reaction to' frustration. The empírical verification of the proposed model consisted of a pilot research to prove the relatlonship between the 'locus of control' variable and the ·tolerance to frustration (under certain aspects). Paralelly, we were able to examine the role of the variable - university education. We studied a group of university students and the results indicated that the interns presented a move mature level of tolerance to frustration. The students persistance in attaining goals and ability to initiative before frustrating sltuat1.ons revealed this higher level of maturity. Despite the 'locus of control', and concerning the University career education students resulted more intrapunitive than others. The analysis of the influence of the kind of frustrating situation, finally showed that the circunstances involving the 'threatening of the ego' led to an emotional discharge of the gul1ty type In detriment to initiative. In addition the extrapunitive reections were more moticiable during those situations in which the subject had its goals blockaded. / Este estudo visa analisar a interrelação teórica e epistemológica entre a teoria da aprendizagem social, mais precisamente em termos de seu constructo 'locus de controle' de Rotter e a teoria da frustração, tal como desenvolvida por S. Rosenzweig. Através de um reestudo das ·teorias da frustração e proposto um modelo, capaz de avaliar a influência da percepção social determinada pela direção do 'locus de controle' na reação à frustração. São examinadas três possíveis explicações teóricas para determinação das diferenças na percepção do controle a primeira em função da teoria da aprendizagem, a segunda em termos psicodinâmicos e a terceira em função de disposições inatas. E apresentada uma revisão das tentativas e comprovações experimentais quanto ao constructo 'locus de controle ' e à reação à frustração. A verificação empírica do modelo aqui proposto ' consistiu numa pesquisa piloto apta a comprovar, sob alguns aspectos, a relação entre a variável 'locus de controle' e a tolerância à frustração. Paralelamente foi possível examinar o papel da variável 'formação universitária'. Utilizou-se um grupo de estudante e universitários e os resultados ' indicaram que, sujeitos com 'locus interno' apresentam um nível mais amadurecido de tolerância à frustração por revelarem maior persistência .em seus objetivos e capacidade de iniciativa em situação frustrante. Quanto ao tipo de formação universitária. estudantes de pedagogia mostraram-se mais intrapunitivos que estudantes de outras áreas independentemente da direção do 'locus de controle'. Um exame da influência do tipo de situação frustradora permitiu concluir que 'circunstâncias que envolvem 'ameaça do eu' levam a uma descarga emocional do tipo culpa em detrimento da iniciativa e aquelas situações em que o sujeito e bloqueado em um objetivo ressaltam as reações extra punitivas.

De l'impact des variations temporelles sur les transitions formantiques / On the impact of t emporal variations on formant transitionsAbuoudeh, Mohammad 26 June 2018 (has links)
Cette étude permet d’explorer les variations spectrales provoquées par deux types de changements temporels qui résultent respectivement de l’opposition de longueur vocalique (variations intrinsèques) et des variations du débit de parole (variations extrinsèques). Trois protocoles expérimentaux ont été conçus, deux en arabe jordanien et un en français, pour examiner ce phénomène. Un intérêt particulier a été porté aux occlusives produites dans des séquences CVC dans le but d’évaluer la coarticulation de la consonne en position initiale et finale. La durée des voyelles et la fréquence des trois premiers formants au début ou à la fin et au milieu de chaque séquence ont été mesurées dans chaque condition de longueur et de débit. Les équations de locus ont été utilisées afin de décrire la relation CV/VC quand elle subit ces deux types de variations. Selon les résultats, la qualité de la voyelle et de la consonne est influencée par l’opposition de durée et par le débit de parole de manière distincte. Le changement généré par les variations temporelles est évalué à l’aide des équations de locus et à travers des analyses de dispersion. Ces outils révèlent qu’il existe un chevauchement coarticulatoire plus important quand la durée de la voyelle est réduite, peu importe l’origine des variations temporelles dans les deux langues (intrinsèque et extrinsèque). Par contre, les variations temporelles impactent la classification des occlusives de manière distincte selon leur origine. / The aim of this study is to examine the different spectral variations that are impacted by two types of temporal modifications: phonological vowel length contrast (intrinsic variations) and varying speaking rates (extrinsic variations). Three experiments, two on Jordanian Arabic and one on French, were conducted to investigate this phenomenon. We were interested in stop consonants produced in the initial and the final positions in CVC sequences. Vowel duration and the frequency of the first three formants were measured for each vowel length and speaking rate. In addition, locus equations were computed to measure the impact of time variations on CV / VC coarticulation. According to the results, the vowel and consonant qualities are influenced both by vowel duration contrasts and by speaking rate modifications in different ways. Such modifications are evidenced by locus equations and by dispersion analyses as well. These two quantification tools revealed that there is greater coarticulatory overlap when the duration of the vowel is reduced, regardless of the origin of temporal variations in the two languages (intrinsic and extrinsic). On the other hand, temporal variations affect the classification of the stop consonant differently according to their origin.

Étude de l’autoincompatibilité chez la chicorée (Cichorium intybus L., Asteraceae) : cartographie génétique et physique du locus S / Study of the self-incompatibility in chicory (Cichorium intybus L., Asteraceae) : genetic and physical mapping of the locus SGonthier, Lucy 05 July 2011 (has links)
L'autoincompatibilité (AI), généralement sous le contrôle d’un seul locus, le locus S, est la stratégie la plus répandue pour empêcher l'autofécondation chez les plantes hermaphrodites. Les déterminants de la réaction d’AI ont été identifiés dans quelques familles d’Angiospermes. Dans celle des Asteraceae, ces déterminants sont encore inconnus. La chicorée (Cichorium intybus L., Asteraceae) présente un système d’AI sporophytique. Afin d’identifier les déterminants de l’AI de cette espèce, une stratégie de clonage positionnel du locus S a été mise en place.Le locus S de la chicorée avait été cartographié à l'extrémité du groupe de liaison 2. Une carte haute densité a été obtenue à partir d’une approche BSA assistée par marqueurs : 5 marqueurs AFLP ont été identifiés, dont un coségrégeant avec le locus S. A partir d’une importante population (n = 2824), 2 cartes consensus haute résolution de la région du locus S ont été établies, l’une pour les méioses femelles (intervalle de 0,6 cM) et l’autre pour les méioses mâles (intervalle de 1,24 cM), en raison d’un phénomène d’hétérochiasmie.Deux banques BAC de chicorée ont été construites en collaboration avec le CNRGV. Elles ont permis d’initier et d’orienter la marche chromosomique vers le locus S. De plus, 6 clones BAC, soit 546 kb, ont été séquencés et analysés. Un rapport de 0,45 (méiose femelle) à 2 cM/Mb (méiose mâle) a été obtenu. La composition des séquences en éléments répétés et la fraction codante ont été étudiées (banques d’EST de Cichorium sp. et de peptides d’A.thaliana et de V.vinifera). Une relative conservation de la microsynténie a été observée entre ces gènes et leurs homologues chez 5 espèces Dicotylédones. / Generally under the control of one locus, the S-locus, self-incompatibility (SI) is one of the most important strategies to prevent selfing in hermaphrodite plants. Determinants involved in the SI reaction have been identified in some Angiosperm families. In the Asteraceae family, determinants of SI are still unknown. Chicory (Cichorium intybus L., Asteraceae) is a sporophytic SI species. To identify determinants of chicory SI, a positional cloning strategy has been implemented.The chicory S-locus has been assigned to one end of linkage group 2. A high density map have been obtained from a marker assisted BSA (Bulk Segregant Analysis) approach: 5 AFLP markers were obtained, including one co-segregating with the S-locus. From a large population (n = 2.824), 2 consensus high-resolution map of the S-locus region were produced. Due to a heterochiasmy phenomenon, the S-locus was positioned in an interval of 0,6 cM or 1,24 cM considering female or male meiosis, respectively.Two BAC libraries of chicory were produced in collaboration with the CNRGV. They allowed us to start chromosome walking and to turn it toward the S-locus. Moreover, 6 BAC clones, corresponding to 546 kb, were sequenced and analyzed. A ratio of 0,5 Mb/cM for male meiosis and 2,2~Mb/cM for female meiosis were obtained. Repeated element composition and coding part of the sequences were studied (libraries of Cichorium sp. EST and Arabidopsis thaliana and Vitis vinifera peptides). A certain degree of conservation of microsynteny was observed between these genes and their homologues in five Dicotyledon species.

AN ANALYSIS INTO THE FUNCTIONING OF THE S. INTERMEDIUS B196 STREPTOCOCCUS INVASION LOCUS / THE STREPTOCOCCUS INVASION LOCUS IN S. INTERMEDIUS B196Wu, Bryan January 2018 (has links)
The Streptococcus Anginosus Group (SAG) is a group of Gram-positive cocci
which require carbon dioxide to grow. They are commensal members of the
healthy upper respiratory, gastrointestinal and female urogenital tract; however,
they are most commonly known as major pathogens in brain and liver abscesses,
forming both mono- and polymicrobial infections. The Streptococcus invasion
locus (sil), first identified as a virulence factor in Group A Streptococcus (GAS),
has recently been identified in the SAG. The sil locus in GAS is a two component
quorum-sensing system composed of three operons: silAB, coding for a two
component system; silE/D/CR, coding for an ABC transporter and a signal
peptide, and silC, which overlaps silCR on the opposite strand. The presence of
exogenous SilCR activates SilA, which in turn upregulates the transcription of the
silE/D/CR operon. In the SAG, however, silCR and silED have distinct promoters,
and the SAG sil system lacks the silC gene. In this study, I examined the
transcriptional dynamics of the sil system in S. intermedius B196. I determined
that SilA is the major regulator of the genes in the sil system, being one of the
first genes of the system to be expressed, and likely upregulates its own
transcription. I also found evidence suggesting that, despite having its own
promoter, silCR transcription may still be driven by the silED promoter. I also
found evidence that suggests silED may be responsible for the export and/or
processing of bacteriocins targeting closely related species or strains. / Thesis / Master of Science (MSc) / The Streptococcus are a group of bacteria known for causing diseases
ranging from strep throat to flesh-eating disease; however, many species of
Streptococcus are usually non-pathogenic, and live in our bodies without causing
harm. One group of these bacteria, the Streptococcus Anginosus Group (SAG), is
commonly found in our mouths and gut and usually cause no harm; however, in
some cases it can cause infections. How these organisms switch from being nonpathogenic
to pathogenic is unknown, but recently a gene network that appears
to play a role in infection, the Streptococcus invasion locus (sil), was identified in
the SAG. This gene network senses the signals released by other bacteria with
the network, and only turns on when enough signal is present. The goal of this
study is to examine how the system works in the SAG in order to determine how
these bacteria coordinate sil gene expression.
