Dissertations / Theses on the topic 'Selden Roll'

Despite its emphasis on relationships between buyers and sellers, and the effect of emotion on behaviours, marketing literature has not yet investigated customer gratitude as an element of relational exchange. Gratitude is a significant component of personal relationships and may offer important insights into how perceptions of relationship marketing investments impact customer trust in, satisfaction with and affective commitment to a seller. In addition, customer gratitude may provide a more complete explanation of how marketing investments work. Consequently, this research contributes to marketing literature by investigating customer gratitude as a mediating mechanism in the relationship between customer perceptions of relationship marketing investments and customer trust in, satisfaction with and affective commitment to the seller: all dimensions of relationship quality.

Das Selenoprotein Glutathionperoxidase 2 (GPx2) ist ein epithelzellspezifisches, Hydroperoxide-reduzierendes Enzym, welches im Darmepithel, vor allem in den proliferierenden Zellen des Kryptengrundes, exprimiert wird. Die Aufrechterhaltung der GPx2-Expression im Kryptengrund auch bei subadäquatem Selenstatus könnte darauf hinweisen, dass sie hier besonders wichtige Funktionen wahrnimmt. Tatsächlich weisen GPx2 knockout (KO)-Mäuse eine erhöhte Apoptoserate im Kryptengrund auf. Ein Ziel dieser Arbeit war es deshalb, die physiologische Funktion der GPx2 näher zu untersuchen. In Kryptengrundepithelzellen aus dem Colon selenarmer GPx2 KO-Mäuse wurde eine erhöhte Caspase 3/7-Aktivität im Vergleich zum Wildtyp (WT) festgestellt. Zudem wiesen diese Zellen eine erhöhte Suszeptibilität für oxidativen Stress auf. Die GPx2 gewährleistet also den Schutz der proliferierenden Zellen des Kryptengrundes auch bei subadäquater Selenversorgung. Des Weiteren wurde im Colon selenarmer (-Se) und -adäquater (+Se) GPx2 KO-Mäuse im Vergleich zum WT eine erhöhte Tumornekrosefaktor α-Expression und eine erhöhte Infiltration von Makrophagen festgestellt. Durch Fütterung einer selensupplementierten Diät (++Se) konnte dies verhindert werden. In GPx2 KO-Mäusen liegt demnach bereits basal eine niedriggradige Entzündung vor. Dies unterstreicht, dass GPx2 vor allem eine wichtige antiinflammatorische Funktion im Darmepithel besitzt. Dem Mikronährstoff Selen werden protektive Funktionen in der Colonkanzerogenese zugeschrieben. In einem Mausmodell der Colitis-assoziierten Colonkanzerogenese wirkte GPx2 antiinflammatorisch und hemmte so die Tumorentstehung. Auf der anderen Seite wurden jedoch auch prokanzerogene Eigenschaften der GPx2 aufgedeckt. Deshalb sollte in dieser Arbeit untersucht werden, welchen Effekt ein GPx2 knockout in einem Modell der sporadischen, durch Azoxymethan (AOM) induzierten, Colonkanzerogenese hat. Im WT kam es in präneoplastischen Läsionen häufig zu einer erhöhten GPx2-Expression im Vergleich zur normalen Darmmucosa. Eine derartige Steigerung der GPx2-Expression wurde auch in der humanen Colonkanzerogenese beschrieben. Das Fehlen der GPx2 resultierte in einer verminderten Entstehung von Tumoren (-Se und ++Se) und präneoplastischen Läsionen (-Se und +Se). Somit förderte GPx2 die Tumorentstehung im AOM-Modell. Acht Stunden nach AOM-Gabe war im GPx2 KO-Colon im Vergleich zum WT eine erhöhte Apoptoserate in der Kryptenmitte (-Se, +Se), nicht jedoch im Kryptengrund oder in der ++Se-Gruppe zu beobachten. Möglicherweise wirkte GPx2 prokanzerogen, indem sie die effiziente Elimination geschädigter Zellen in der Tumorinitiationsphase verhinderte. Eine ähnliche Wirkung wäre auch durch die erhöhte GPx2-Expression in der Promotionsphase denkbar. So könnte GPx2 proliferierende präneoplastische Zellen vor oxidativem Stress, Apoptosen, oder auch der Antitumorimmunität schützen. Dies könnte durch ein Zusammenwirken mit anderen Selenoproteinen wie GPx1 und Thioredoxinreduktasen, für die ebenfalls auch prokanzerogene Funktionen beschrieben wurden, verstärkt werden. Eine wichtige Rolle könnte hier die Modulation des Redoxstatus in Tumorzellen spielen. Die Variation des Selengehalts der Diät hatte im WT einen eher U-förmigen Effekt. So traten in der –Se und ++Se-Gruppe tendenziell mehr und größere Tumore auf, als in der +Se Gruppe. Zusammenfassend schützt GPx2 also die proliferierenden Zellen des Kryptengrundes. Sie könnte jedoch auch proliferierende transformierte Zellen schützen und so die sporadische, AOM-induzierte Colonkanzerogenese fördern. In einem Modell der Colitis-assoziierten Colonkanzerogenese hatte GPx2 auf Grund ihrer antiinflammatorischen Wirkung einen gegenteiligen Effekt und hemmte die Tumorentstehung. Die Rolle der GPx2 in der Colonkanzerogenese ist also abhängig vom zugrunde liegenden Mechanismus und wird maßgeblich von der Beteiligung einer Entzündung bestimmt.
The selenoprotein glutathione peroxidase 2 (GPx2) is a hydroperoxide-reducing enzyme that is mainly expressed in the gastrointestinal epithelium, especially in the crypt base were the proliferating cells reside. GPx2 expression is maintained even when the selenium supply is limited, which indicates that GPx2 might have an important function in these cells. Indeed, GPx2 knockout (KO)-mice have an enhanced rate of apoptosis in the crypt base. Therefore one aim of this study was to further elucidate the physiological function of the GPx2. Isolated colonic crypt base epithelial cells of selenium deficient GPx2 KO-mice were found to have a higher caspase 3/7 activity than wild type (wt) cells. Moreover they exhibited an enhanced susceptibility for oxidative stress. Thus GPx2 protects the proliferative crypt base cells of the intestine, especially when the selenium supply is limited. Additionally an enhanced expression of tumor necrosis factor α and an enhanced infiltration of macrophages were detected in the colon of GPx2 KO-mice in comparison to the wt. These effects were observed on a selenium deficient (-Se) and -adequate (+Se) diet, but could be prevented by feeding a selenium supplemented (++Se) diet. Accordingly, GPx2 KO-mice have a basal low grade inflammation. This underlines, that GPx2 has an important anti-inflammatory function in the intestinal epithelium. Selenium deficiency is linked to an increased risk of developing colorectal cancer. In a mouse model of colitis-associated colon carcinogenesis, GPx2 had anti-inflammatory and thus anticarcinogenic effects. However, also procarcinogenic functions of the GPx2 have been observed. Therefore, this study aimed to analyse the role of GPx2 in a model of non-inflammation triggered, sporadic colon carcinogenesis induced by azoxymethane (AOM). In preneoplastic lesions of wt mice, an enhanced expression of GPx2 in comparison to the normal mucosa was frequently observed. An upregulation of GPx2 expression has also been described in human colon carcinogenesis. GPx2 KO mice had less tumors (-Se and ++Se) and less preneoplastic lesions (-Se, +Se) than wt mice. Accordingly GPx2 promotes colon carcinogenesis in the AOM-model. Eight hours after AOM-application, a higher rate of apoptosis was observed in the mid-crypt region of the colon of GPx2 ko mice in comparison to wt mice in the –Se and +Se groups, but not in the ++Se group or in the crypt base. Thus GPx2 might act procarcinogenic by preventing the elimination of cells with DNA-damage in the tumor initiation stage. Similarly, the enhanced GPx2-expression in preneoplastic cells could promote tumorigenesis by protecting these cells from oxidative stress, apoptosis or antitumor immunity. This effect might be enhanced by other selenoproteins like GPx1 or thioredoxin reductases that have also been reported to possess procarcinogenic properties and it might be closely related to the regulation of the redox state of tumor cells. In wt mice, the selenium content of the diet turned out to have a rather U-shaped effect on colon carcinogenesis. In the –Se and ++Se groups, wt mice tended to have more and larger tumors than in the ++Se group. In conclusion, GPx2 protects the proliferating cells of the intestinal crypt base, but it could also protect proliferating transformed cells and thus promote sporadic, AOM-induced colon carcinogenesis. In contrast, GPx2 acted anticarcinogenic in a model of colitis-associated colon carcinogenesis due to its antiinflammatory properties. Thus, the role of GPx2 in colon carcinogenesis depends on the underlying mechanisms, especially on the involvement of an inflammation.

Retirement affords retirees increased time for participation in salutary activities like physical activity. Yet, evidence is mixed as to whether or not retirees use this time to increase their participation in physical activity. Greater knowledge of the factors affecting physical activity participation in retirement is needed. Retirement is also a life transition ripe with opportunity to redefine one's identity and place greater attention on health-enhancing behaviours. Thereupon, this dissertation was rooted in the self literature, as self perceptions such as identity and possible selves may be particularly relevant for understanding physical activity in retired individuals. As a result, the first aim of this dissertation sought to confirm, in a preliminary study (Study 1), the relationship between possible selves, physical activity identity and physical activity in retirees. Through questionnaire data collected concurrently, Study 1 showed that identity and possible selves were related to physical activity (Article 1). Moreover, positive associations were found between possible selves focused on physical activity and physical activity identity. Subsequently, the relationships between these variables were further probed to determine whether exercise identity mediated the relationship between physical activity possible selves and physical activity (Article 2). Questionnaire data collected across three time points (one month apart) showed that identity mediated the relationship between possible selves and behaviour - all related to physical activity. Together, these findings represented an important first step toward designing a relevant intervention for retirees which informed the second aim of this dissertation (Study 2). A possible selves intervention designed to increase physical activity identity and physical activity was tested (Article 3). Changes in these variables were compared across three groups of an experimental design: a repeated possible selves intervention, a one-time possible selves intervention, and a control group. All groups reported marginally higher levels of physical activity and physical activity identity, inconsequential to group assignment. Overall, the present dissertation makes contributions to the self literature especially with regards to new retirees. Nevertheless, limitations are acknowledged and discussed. Finally, future research avenues are presented.

Diese Dissertation umfasst drei Aufsätze über die Rolle von Informationsintermediären und Intermediäre mit Aufsichtsfunktionen in Kapitalmärkten. Der erste Aufsatz untersucht, ob sich verschiedene Leerverkäufer bei ihrer Auswahl von Zielunternehmen anhand von sichtbaren Merkmalen unterscheiden. Die Ergebnisse zeigen, dass Hedgefonds und Investmentmanager im Durchschnitt größere und jüngere Unternehmen bevorzugen, während sich Banken auf Unternehmen mit weniger Restatements der Finanzdaten und einem höheren Verschuldungsgrad konzentrieren. Der zweite Aufsatz beschreibt, wie Unternehmen auf aktivistische Leerverkäuferberichte reagieren. Es wird festgestellt, dass die Antwortrate erheblich steigt, wenn der Bericht von deutlich negativen abnormalen Renditen begleitet wird und wenn die Leerverkäufer neue Beweise vorlegen. Dies stimmt mit der Vorstellung überein, dass Leerverkäufer als Informationsintermediäre fungieren können. Eine Nichtbeantwortung ist außerdem ist mit einer weniger negativen Aktienkursreaktion bei Veröffentlichung und mit weniger nachteiligen Ergebnissen verbunden. Die dritte Aufsatz fokusiert sich auf so-genannte Monitoring Trustees. Sie sind bei der Überwachung von Banken behilflich, die in der Europäischen Union während der letzten Finanzkrise staatliche Beihilfen erhalten haben. In einer von Hand gesammelten Stichprobe werden die Merkmale und Aufgaben dieser neu implementierten Aufseher und ihre Rolle im Zusammenhang mit dem Berichtsverhalten der Banken untersucht. Die Ergebnisse deuten darauf hin, dass diese zusätzlichen Aufseher die Transparenz und das Berichtsverhalten der Banken bei der Finanzberichterstattung beeinflussen können, insbesondere wenn die Berichterstattung über Kreditverluste und Anpassungen der Geschäftsberichte berücksichtigt werden. Der zweite Aufsatz wurde im Journal of Accounting Research (https://doi.org/10.1111/1475-679X.12356) publiziert.
This dissertation comprises three essays on the role of information and monitoring intermediaries in capital markets. The first essay investigates whether different short sellers vary in their selection of target firms using observable firm characteristics. Results show that hedge funds and investment managers on average prefer larger and younger firms, whereas banks focus on firms with fewer restatements and a higher leverage. The second essay provides descriptive evidence on how firms respond to activist short seller reports and how these responses are associated with outcomes for the targeted firms. It finds that the response rate increases substantially when the report is accompanied by significantly negative abnormal returns and when the short sellers provide new evidence which is consistent with the idea of short sellers acting as information intermediaries. Not responding is associated with a less negative stock price response when the report is released and fewer adverse outcomes. The third essay shifts the attention to Monitoring Trustees who assist in the supervision of banks that have received state aid in the European Union during the last financial crisis. It explores in a hand-collected sample the characteristics and duties of these newly implemented monitors and it studies the role of these supranational monitors and the banks’ reporting behavior. Results suggest that these additional supervisors can influence the banks financial reporting transparency and reporting behavior when mainly loan loss reporting and restatements are accounted for. The second essay has been published in the Journal of Accounting Research (https://doi.org/10.1111/1475-679X.12356).

L'objet de cette these est de cerner les effets differencies des pratiques educatives familiales sur le developpement de l'identite sexuee chez l'enfant. L'influence de l'implication parentale, mais aussi de la conformite aux roles de sexe et de la stereotypie du pere et de la mere est recherchee sur deux composantes de l'identite sexuee, concernant l'acquisition des roles de sexe chez l'enfant. Dans une perspective socio-cognitive, nous nous penchons sur l'identite sociale de sexe (apprehendee par la constance de genre, les connaissances des roles de sexe et la flexibilite du schema de genre) et sur l'image sexuee de soi (saisie par le choix des partenaires, les preferences d'activites et les comportements de jeu) de l'enfant prescolaire. Pour ce faire, nous avons interroge 23 enfants et leurs deux parents au travers de differents outils. Un questionnaire compose de 12 echelles d'attitudes, du bsri et du psai a permis de saisir le degre d'implication, de conformite et de stereotypie du pere et de la mere. Concernant l'enfant de 4 ans 9 mois (= 1 mois), nous avons adapte deux outils anglo-saxons: le serli et le ssm. Nous avons egalement fait une observation de type ethopsychologique des comportements de jeu de l'enfant face a des jouets stereotypes et contre-stereotypes. Contrairement aux hypotheses posees, la conformite et la stereotypie parentale permettent a l'enfant de se degager plus precocement des stereotypes de sexe. Hormis les effets de l'asymetrie sociale entre les deux groupes de sexes, nous relevons une relation entre pratiques educatives et identite sexuee qui nous parait etre celle d'un besoin de conformite chez l'enfant. Face au manque de clarte des reperes parentaux sur les differences entre les deux sexes, l'enfant construit ses propres normes de references concernant son appartenance sexuee
This work aims to understand the effects of family educational practices effects on the child's gender development. We study the influence of the parental involvement, the gender role conformity and the parental stereotypy on two components of gender role attainments. From a socio-cognitive point of view, we examine the gender social identity (apprehended by gender consistency, the knowledge of gender roles and gender schema flexibility) and the gender self concept (apprehended by the playmate preferences, the favourite activities and the playing behaviours) of the pre-school child. We have observed 23 children and their parents with several instruments. A questionnaire composed by 12 behaviours scales, the bsri and the psai have allowed us to reach the degree of involvement, conformity and stereotypy of the father and mother. Concerning the 57-months-old child, we have adapted two american instruments: the serli and the ssm. We have also made an ethopsychological observation of the playing behaviours of the child with stereotyped and cross-stereotyped toys. Contrary to our hypothesis, parental conformity and stereotypy help the child for early disengagement from gender stereotypes. We can observe the effects of social asymmetry between the two gender groups. But the relation between family educational practices and gender identity is also to be found in the child's need of conformity. When the parental landmarks of the gender differences are not clear, the child will construct his own reference norms about his belonging to a gender group

Selenium (Se) is an element with important health implications that is emitted in significant amounts from volcanoes. Attracted by the fertility of volcanic soils, around 10% of the world population lives within 100 km of an active volcano. Nevertheless, the behaviour of Se in volcanic environments is poorly understood. Therefore, the main aim of this thesis is to investigate the role of soils in the Se cycling in volcanic environments. Prior to the geochemical studies, precise and accurate methods for the determination of Se contents, speciation and isotopic signatures were developed. Afterwards, a combination of field studies and lab controlled experiments were performed with soils from two contrasting European volcanic settings: Mount Etna in Sicily (Italy) and Mount Teide in Tenerife (Spain). The results showed a strong link between Se behaviour and soil development, indicating that Se mobility in volcanic soils is controlled by sorption processes and soil mineralogy.
El selenio (Se) tiene afectas sobre la salud y es emitido por los volcanes. Atraída por la fertilidad de los suelos volcánicos, un 10% de la población mundial vive <100 km de volcanes activos. Sin embargo, el comportamiento geoquímico del Se en ambientes volcánicos es aún poco conocido. El objetivo de esta tesis es contribuir a la comprensión del papel del suelos en el ciclo del Se en medios volcánicos. En una primera etapa se desarrollaron métodos analíticos para determinar el contenido, la especiacíon y las relaciónes isotópicas del Se. Los estudios geoquímicos se realizaron con suelos de dos lugares con características muy distintas: el Monte Etna (Italia) y el volcán Teide (Tenerife). Los estudios de terreno y de laboratorio revelaron una gran interrelación entre el comportamiento del Se y el desarrollo de suelos, y que la movilidad de Se está controlado por los procesos de adsorción y la mineralogía en suelos volcánicos.

Dites-moi de quel sexe etes-vous, je vous dirais comment vous etes ou comment vous devriez etre, puisque toutes les femmes ressemblent a une seule femme et tous les hommes a un seul homme. L'un sensible l'autre intelligent, l'un irraisonnable l'autre raisonnable, l'un inferieur l'autre superieur. . . En fait, on a du mal a concevoir l'etre humain en dehors de ces categories binaires bien definies. Et c'est la que reside notre incapacite a comprendre et a accepter l'autre (l'autre sexe) chaque fois qu'il se comporte differemment de ce qui a ete convenu au prealable comme etant son genre. Or, cette correspondance etroite qu'on a etablie entre sexe male et genre masculin d'un cote et sexe femelle et genre feminin d'un autre cote, nous cause beaucoup de tort. En effet, n'est-ce pas regrettable de denier aux hommes le droit d'etre tendres, doux, sensibles et affectueux ? et n'est-ce pas regretable de denier aux femmes d'etre libres, independantes, intelligentes et creatrices ? ar-rawd al-'atir fi nuzhat al-hatir est l'un de ces ouvrages qui traitent de l'identite masculine et celle feminine, en tracant l'image d'une femme- modele et d'un homme-modele a l'image de ce que nous venons de decrire. Mais, a la fin de notre analyse, nous avons constate que les vrais desirs de l'homme ne sont pas les memes que ceux qu'il declare publiquement. En effet c'est cette meme femme qu'il designe comme etant son ennemie qui est la vraie heroine de ses fantasmes. C'est une femme puissante, experte dans le domaine de l'amour, elle est meme perverse, libertine et tres sensuelle. Mais il faut encore que l'homme avoue publiquement ce qu'il est et ce qu'il desire reellement. Car c'est a ce moment la seulement qu'on peut rever d'un monde meilleur, d'un monde ou le genre n'a pas de sexe
Tell me what sex you are, i would tell you how you are or either how you should be, since all women look like only one woman and all men look like only one man. One is tender, the other is intelligent, one is irrational, the other is reasonable, one is inferior, the other is superior. . . In fact, it's difficult to conceive the human being outside of these very definite binary categories. And this how appears our inability to understand and to accept the other (the other sex) every time that he behaves differently of what has been previously agreed as being his kind. However, this narrow correspondence established between male sex and masculine kind on one side and female sex and feminine kind of another side, causes us a lot of harm. Isn't regrettable to deny to men the right to be tender, soft, sensitive and loving ? and isn't regrettable to deny to women to be free, independent, intelligent and creators ? ar-rawd al-atir fi nuzhat al-hatir is one of these works that treats the masculine and feminine identities, while drawing a woman's model and of a man model. But it is necessary again that the man confesses publicly what he is and what he really wants, at that moment only, we can dream of a better world, a world where the kind doesn't have a sex

La littérature suppose implicitement l'existence d'un déterminisme biologique pour expliquer les différences entre les hommes et les femmes entrepreneurs. Par l'analyse des représentations de la performance, nous questionnons les stéréotypes sexués en mobilisant les notions de sexe (homme/femme) et de genre (féminité/masculinité) : le sexe est-il une variable pertinente pour expliquer les différences hommes/femmes en matière de représentation de la performance d'entreprise ?Trois études quantitatives utilisant une ANOVA et des t-Test ont analysé les données issues de 244 entrepreneurs. Une étude qualitative auprès de 6 entrepreneurs a permis de modéliser les représentations de la performance. Nous montrons que les différences de représentations de la performance d'entreprise ne sont expliquées ni par les catégories de sexe (Homme et Femme), ni par celles du genre (Masculin, Féminin, Androgyne, Indifférencié) définies par le Bem Sex Role Inventory. Nous confirmons également que les représentations collectives de la performance ont évolué et vont bien au-delà de la simple quête de profit, et sont plus rattachées à des valeurs sociales actuelles
Literature tends to assume implicitly the existence of a biological determinism to explain the differences between men and women entrepreneurs. Our aim was to study the representations of business performance based on the notion of sex (biological sex: female & male), and gender (the social sex: feminity & masculinity). Could masculinity and/or femininity reveal differences in representing business performance between men and women entrepreneurs? Three quantitative studies, based on ANOVA and t-Test, were used to analyze data collected by questionnaire from 244 entrepreneurs. A qualitative study was used to model data collected during individual interview of six entrepreneurs.We found that differences in representing business performance cannot be revealed neither by the distinction of category of sex (male / female), nor by gender categories (Male, Female, Androgynous, Undifferentiated) as defined by the Bem Sex Role Inventory. Also, we confirm that collective representations of the performance by the entrepreneurs have evolved and go well beyond the simple pursuit of economic profit, and can be more closely related to current social values

Cette recherche a pour objectif d’analyser l’évolution des rapports de genre au cours de l’exercice des mandats électifs. Il s’agit d’appréhender l’action socialisante des fonctions d’élu à travers la notion de carrière politique genrée. Dans un premier temps, nous présentons les injonctions reposant sur les femmes et les hommes qui candidatent à différentes élections locales. Pendant cette période d’initiation aux rôles politiques, les femmes incarnent le renouvellement tandis que les hommes symbolisent l’expérience. Ces représentations et pratiques genrées varient néanmoins suivant les configurations électorales. La deuxième partie s’intéresse aux processus de sélection des élus selon le genre et à leurs conséquences quant à l’investissement dans les responsabilités électives. Enfin, dans la troisième partie, nous montrons que, pour faire carrière, les femmes doivent concilier habilement les pratiques perçues comme masculines et féminines en politique
This research concerns the advancement of gender roles and relationships during politician career. We analyze female and male politician socialization in three parts. First, election campaigns introduce to female or male role. They turn women to outsiders whereas men embody experienced politician. Then, selection leads women to lowly work. Finally, they try to highlight their position by claiming a female ethical code. However, to stay or improve their status, they must learn male behaviors too. Nevertheless, they do not wholly forgive female politician ethical code

The aim of the thesis is to understand why European countries show a very different picture of female employment (in their fertile ages) which is not the case for men of the same age. We shed light on the various positions of countries in this framework of earner-carer models, in analysing policy designs, policy outcomes and policy determinants. That is, respectively, family policy indicators, employment of mothers and childless women, gender role attitudes and their interacting effect with policies and employment outcomes. We have used a wide range of primary or secondary quantitative and qualitative data to carry out our comparative analysis, mixing approaches, techniques and methods, from micro-econometric models to macro-level harmonised indicators, supplemented with a case study.

The dissertation is divided in three parts, each focusing on one question:

La présente thèse dont la problématique émerge de l'existence des rapports sociaux de sexe sur la scène sociale au Liban, vise à y trouver une contribution du système scolaire dans la formation de l'identité sexuée chez les élèves au primaire. Son objectif principal est d'explorer les façons dont l'institution scolaire traite les élèves des deux sexes, et qui engendre ensuite son rôle indéniable dans l'édification du genre chez eux-elles. L'hypothèse principale suppose à cet égard qu'une telle construction identitaire ne s'effectue pas de la même manière chez les filles et les garçons au sein des classes. Au début, les démarches méthodiques du travail, basées sur une pré-enquête par entretiens semi-directifs menés auprès des directeurs de 18 établissements scolaires au sud-Liban, ont décelé chez ces responsables, la présence d'une mentalité sexiste. A noter qu'ensuite, lors d'une série de 225 séances d'observation dans 11 classes du primaire, durant 4 mois successifs, on a pu affirmer la présence des effets enseignant-élève différenciés selon le sexe, tout en soulignant l'inculpation des pratiques des instituteurs-trices, puisqu'ils-elles prédéterminent souvent, et selon son sexe, la manière d'interagir avec l'enfant, d'ici découle la discrimination préalable. A côté de ça, l'analyse du contenu des manuels scolaires, faite sur six livres de maths à l'usage des classes enquêtées, a vérifié que ces livres motivent nettement une représentation stéréotypée de la société, d'où surgissent des positions sexuellement différenciées, témoignées par leur contenu. D'autre part, la majorité des classes observées, semble prêter à la socialisation sexuée, ce que montre l'étude de plusieurs variables durant les séances d'apprentissage, et qui peut aboutir, d'une façon ou d'autre, à généraliser l'universalisme masculin, et par suite à renforcer la domination masculine à travers des rapports hiérarchiques liés à l'appartenance sexuée des apprenant-e-s
The present thesis whose problematical emerges from the existence of the socialized terms of sex on the Lebanese social scene, where it aims to find a contribution of its scholar system in the formation of sexual identity among the child students in the primary cycle. So the main objective is to explore the ways in which the scholar institution treats the students of both sexes, that gives rise to their obvious role in the edification of the gender in the students. In this respect, the principal hypothesis supposes that such an identity construction can’t be effected evenly with girls and boys in the classes. At the beginning, the methodic proceedings of the study, based on a pre-inquiry via semi-directive talks conducted with the directors of 18 scholar establishments in south-Lebanon, have revealed in those responsible, the presence of sexual mentality. Further note that during a series of 225 observation sessions of 11 primary classes, made successively in 4 months, we could affirm the presence of teacher-student differentiated effects related to the sex of the latter, while noting an inculpation of teacher’s practices, for he/she often predetermines according to his sex, the mode of interacting with a child, a preliminary discrimination can therefore be deduced. In addition to that, a content analysis of 6 maths manuals belonging to the classes concerned, has been done, it verifies that these books motivate clearly a stereotyped representation of the society, where loom up sexually differentiated positions witnessed by their contents.On the other hand, the majority of the observed classes seems to enhance sexualized socialization, which is shown by many variables during apprenticeship sessions, this may lead in certain manners to generalize the masculine universalism and to strengthen therely the domination of the strong sex, through hierarchical terms linked to the sex of the student

Příbram uranium and base-metal district is the most important vein uranium district in the Czech Republic. The main ore was represented by uraninite there and the occurrences of selenium mineralization are directly connected to it. The presence of selenides was not confirmed during the mining activities. Major development of the uranium-carbonate mineralization was found in the Bytíz deposit in the central part of the uranium district. All known occurrences of selenides have been found from this area only so far. Antimonselite, athabascaite, bellidoite (?), berzelianite, brodtkorbite, bukovite, clausthalite, dzharkenite, eskebornite, eucairite, giraudite, hakite, cadmoselite, klockmannite, naumannite, permingeatite, sabatierite, tiemannite and umangite, as well as the new unnamed selenium analogue of chalcostibite were newly identified from the dump material from the shafts No. 16 and 11A. The extremely Hg-rich hakite, which contains up to 30 wt.% of Hg, is the most remarkable mineral from the tetrahedrite group of minerals. The pertinence of the Hg-hakite was verified by means of the transmission electron microscopy. Uncommon recently formed supergene selenium association is represented by molybdomenite, munakataite and piretite. A large scale of associated minerals was found in association with...

For the suppliers pursuing the competitive advantages; they would like to know what kind of the relationships (e.g. retaining simple a buying selling, signing a long-term constract, or forming a strategic alliance )should be construited between the suppliers and the buyers. No matter what kind of the relationship been established, it must achieve to care for the enterprise’s profit and the customer satisfaction at the same time. From the viewpoint of the supply chain management, the buyer and the seller should act as partners to minimize the total system cost and meet the customer needs Therefore, the purpose of the this study aims to discover the acting role of relationship structure in trust. Based on the previous reseaches related to trust, we proposed a model with trust as intermediate variable to analyze how four constructs (or latent variables ),i.e communication, intention of investment, dependence, and contract, in influence the cooperative attitude of buyers. Relying the uniform purchasing of senior high school in Taipei as the empivical case, the study utilized the questionnaire to collect the data, and structural equation modeling (S.E.M) method to validate the theoretical model. The results of this research can be summarized as follows: communication demonstrated a significant positive relationship association with cooperative attitude of two parties, customer need, and intention of investment in the recognition of the customer relationship; the buyer depend on the supplier can affect the trust of buyer had the positive relationship; a significant positive relationship between dependence of buyer and supplier contract implement; contract signing can not affect the trust of buyer; a direct positive relationship between intention of investment of supplier and trust of buyer; and a significant positive relationship between trust and cooperative attitude of two parties.

Afro-Puerto Rican Mayra Santos-Febres's novel Sirena Selena vestida de pena (2000) demonstrates the intrinsic social relationship that exists between generations in Puerto Rico and Dominican Republic. The historical similarity between these regions permits a comparison in life stories of marginalized peoples. Puerto Rican godmothers and transvestites Martha Divine and Valentina Frenesâi prepare goddaughter, quinceänera and bolerista Sirena Selena in her performance in order to launch a career and conquer the strategies of survival. Meanwhile, Dominican millionaire Hugo Graubel manages his life publicly as a heterosexual husband and privately as a gay man and strongly attempts to capture enigmatic Sirena Selena. Whereas the Dominican, pre-adolescent, poor, and mulatto Leocadio discovers the veiled world of tourism that offers alternate possibilities of economic survival. The previous generations' transgression of society's binary definitions created alternate spaces that continue to pave the way for future generations that will refuse and resist conforming to static patriarchal and heterosexual mainstream classifications

This study explores relationships among insurance female sellers’ multiple roles and role conflict from spillover theory. It has four purposes：1) to examine the relationship between insurance female sellers’ multiple roles and role conflict；2) to examine the relationship between multiple roles, job satisfaction, family satisfaction and subjective well-being；3) to examine the relationship between role conflict and job satisfaction, family satisfaction and subjective well-being；4) social support modulate the relationship between role conflict and job satisfaction, family satisfaction, subjective well-being. The research used the survey of multiple roles, role conflict, JSS, family satisfaction, social support and CHI(short). The subject of this study were insurance female sellers in Taiwan. A sample of 460 insurance female sellers volunteered to participate in the study. The researcher used the statistical techniques as Pearson r, t-test, one-way ANOVA and LSD post hoc to test and examine research hypotheses. The major findings are : 1)There is a part relationship between multiple roles and role conflict. 2)There is no relationship between multiple roles and job satisfaction. 3)There is a relationship between role conflict and job satisfaction. 4)There is a relationship between multiple roles and family satisfaction. 5)There is a relationship between role conflict and family satisfaction. 6)Multiple roles, role conflict, job satisfaction and family satisfaction correlated with subjective well-being. 7)Social support modulate the relationship between role conflict and job satisfaction. Implications of the findings for insurance companies or some companies are discussed.

Previous research using future time perspective or possible selves frameworks provided evidence that learners with definite and elaborate goals, and future self-guides are more motivated in school tasks (Reeve, 2009; Yowell, 2000), exert more effort, demonstrate persistence, and show greater performance (De Volder & Lens, 1982; Lens et al., 2002; Simons et al., 2000), and learners with positive possible selves were better able to face failure, demonstrated better performance, had higher levels of self-esteem, showed more persistence on tasks, and depicted greater motivation (Cross & Markus, 1994; Oyserman et al., 2004; Unemori et al., 2004). The purpose of this study was to investigate the role of future orientation constructs, future time perspective and possible selves, on Turkish college level learners' motivation to learn English and their identity construction, and how future projections of themselves as L2 users (the ideal L2 self, the ought-to L2 self, and feared L2 self) impacted their motivation to learn English and their identities. A total of 299 Turkish graduate students studying in the United States participated in the study. Also, this study examined the extent to which adding a measure of the feared L2 self construct contributed to explaining motivation to learn English and identity construction. The data were collected via surveys and interviews, and they were analyzed quantitatively, using qualitative data for triangulation. Findings suggested that the L2 motivational self-system (Dornyei, 2005, 2009) contributed to explaining Turkish learners' motivation to learn English and their oriented identities. Also, adding a feared L2 self variable to measures of the L2 motivational self system could help explain learners' identity construction but not their language learning motivation. In addition, future time perspective connectedness and value were not useful in explaining the L2 motivation, but future connectedness was found to be related to the ideal L2 self and feared L2 self, and valuing the future goals was related to the ought-to L2 self. Qualitative data showed that learners presented combination of several identities, including national and oriented. They imagined themselves as professional and successful English users, and their L2 related worries included losing their native language and being seen as "assimilated" or as "showing off" individuals.

Cette étude de cas, composée de trois articles, examine les diverses sources d’explication de l’écart salarial selon le genre chez les professeurs d’une grande université de recherche canadienne. Le premier article analyse les écarts selon le genre sur les primes “de marché” à partir de données d’un sondage réalisé auprès des professeurs en 2002. Une analyse des correspondances donne une solution à deux facteurs dans laquelle le second facteur oppose clairement les professeurs qui ont reçu une prime à ceux qui n’en n’ont pas reçue. Le genre est fortement associé à ce facteur, la catégorie “femme” se retrouvant du côté de l’axe associé à l’absence de primes de marché. Les résultats de la régression logistique confirment que le secteur d’activité, la fréquence des contrats de recherche, la valorisation du salaire ainsi que le rang combiné à l’ancienneté sont reliés à la présence de primes de marché, tel que proposé par les hypothèses. Toutefois, même après avoir contrôlé pour ces relations, les femmes sont toujours près de trois fois moins susceptibles de s’être vu attribuer des primes de marché que leurs homologues masculins. Dans l’ensemble, les résultats suggèrent que dans un contexte où les salaires sont déterminés par convention collective, la réindividualisation du processus de détermination des salaires — en particulier le versement de primes de marché aux professeurs d’université — peut favoriser la réapparition d’écarts de salaire selon le genre. Le second article est réalisé à partir de données administratives portant sur les années 1997 à 2006. Les contributions respectives de quatre composantes de la rémunération à l’écart salarial selon le genre y sont analysées, soit le salaire de base, l’accès au rang de professeur titulaire, l’accès aux primes de marché et chaires de recherche du Canada, de même que les montants reçus. Les composantes varient quant à leur degré de formalisation. Ceci permet de tester l’hypothèse selon laquelle l’ampleur de l’écart salarial selon le genre varie en fonction du degré de formalisation des composantes salariales. Nous déterminons également dans quelle mesure l’écart selon le genre sur les diverses composantes de la rémunération varie en fonction de la représentation relative des femmes professeurs au sein des unités. Les résultats démontrent l’existence de variations dans l’ampleur des différences selon le genre en fonction du degré de formalisation des pratiques de rémunération. Qui plus est, après contrôles, la rémunération est plus faible dans les unités où les femmes sont fortement représentées. Le dernier article examine les mécanismes pouvant mener à un écart selon le genre en ce qui a trait à l’accès aux primes de marché chez les professeurs de l’institution. Les processus d’attribution de ces suppléments salariaux sont examinés à partir d’entretiens réalisés avec 17 administrateurs à tous les niveaux hiérarchiques de l’institution et dans une diversité d’unités académiques. Les résultats suggèrent que les différences selon le genre pourraient être liées à des caractéristiques spécifiques du processus d’attribution et à une distribution inégale des primes aux unités à forte représentation féminine. De façon générale, les résultats démontrent que l’écart de rémunération selon le genre chez les professeurs de cette université n’est pas totalement expliqué par des différences dans les caractéristiques individuelles des hommes et femmes. L’analyse révèle que l’écart réside dans des différences selon le genre en ce qui a trait à l’accès aux primes de marché et aux chaires de recherches du Canada et, dans une moindre mesure, au rang de professeur titulaire. Aucune différence n’est observée sur le salaire de base et le montant des primes salariales reçues, que celles-ci soient dites de “marché” ou associées à une chaire de recherche du Canada. Qui plus est, on constate que la rémunération est plus faible dans les unités où les femmes sont le mieux représentées. L’accès différencié selon le genre aux primes de marché qui est observé pourrait être lié à certains processus organisationnels qui limitent les probabilités d’octrois à des femmes. Les femmes pourraient être particulièrement désavantagées dans ce système d’octroi, pour plusieurs raisons. L’existence de différences selon le genre en ce qui a trait aux dispositions ou habiletés des individus à négocier leur salaire est évoquée et supposée par certains administrateurs. Un accès limité aux informations concernant la politique de primes pourrait réduire la probabilité que des femmes tentent d’obtenir ces suppléments salariaux. Les directeurs d’unités, qui sont en majorité des hommes, pourraient être biaisées en faveur des professeurs masculins dans leurs évaluations s’ils tendent à favoriser ceux qui leurs ressemblent. Il est également possible que les directeurs d’unités où les femmes sont les mieux représentées n’aient pas reçu d’information sur les primes de marché ou que des traditions disciplinaires les aient rendu réticents à demander des primes.
This case study examines the various sources of explanation of the gender pay gap among professors at a large Canadian research university. It comprises three articles. The first article analyzes gender differences in “market supplements” using data from a survey of professors conducted in 2000. The correspondence analysis produces a two-factor solution in which the second axis clearly opposes faculty who receive market supplement to those who do not. Gender is strongly related to this factor, with the female category on the side of the axis associated with the absence of market supplement. The results of the logistic regression confirm that field of specialization, frequency of external research contracts, faculty members’ values and attitudes towards remuneration and seniority within rank are all related to the award of market supplements, as hypothesized. However, women were still almost three times less likely than men to have been awarded market supplements after controlling for these relationships. Overall, the results suggest that within a collective bargaining context, reindividualization of the pay determination process — notably, the payment of market supplements to faculty — may reopen pay differences by gender. The second article uses administrative data for years 1997 to 2006. We estimate the respective contributions to the gender pay gap of four pay components: base pay, promotion to full professor, access to market supplements and Canada research chairs as well as the amounts received. These are characterized by various levels of formalization. This allows testing the hypothesis that the magnitude of gender differences in pay varies with the extent of formalization of pay components. We also determine how gender differences on each pay component vary according to the relative representation of female faculty members within units. We find some evidence that the magnitude of gender differences varies with the degree of formalization in remuneration practices. We also find that, other things being equal, pay is lower in units with a high proportion of females. The last article examines the mechanisms that may lead to gender differences in access to ‘market supplements’ among professors. The process of awarding pay in excess for the amounts provided for in a collective agreement are examined based on interviews with 17 administrators at all hierarchical levels and in various academic units. Results suggest that gender differences in the likelihood of receiving an award may be related to specific features of the award process and to an unequal distribution of awards to units with strong female representation. Overall, the results show that the gender pay gap among professors at this university is not entirely accounted for by differences in the individual characteristics of male and female professors. The analysis reveals that the pay gap resides in gender differences in access to market supplements and Canada research chairs (CRCs) and, to a lesser extent, to the full professor rank. No difference is found on base pay or on the amounts of pay supplements received, whether they are “market” premiums or supplements associated to a CRC. Furthermore, pay tends to be lower in units where female representation is highest. The observed gender differences in access to market supplements could be due to organizational processes that reduce the likelihood of awards to women. There are several reasons why female faculty members are particularly disadvantaged in this award system. Gender differences in the propensity or ability to negotiate are alleged (and assumed) by some of those negotiating. More limited access to information about supplements reduces the likelihood that women will pursue them. Chairpersons, who are mostly males, may allow gender bias to influence their evaluations of faculty members, perhaps because they tend to favor others like themselves. It may also be that chairpersons from the units where women are better represented do not have access to information about market supplements or that disciplinary traditions make them reluctant to request them.
