Exploring the relation between gender politics and representative government in the Maghreb: analytical and empirical observations
No full textThis thesis uses analytical and empirical methods to explore the relation between gender standards and democratic standards in the Maghreb, which includes Algeria, Morocco, and Tunisia. The analytical approach consists of considering theories that link gender standards and democratic standards, and analyzing whether and to what extent such theories would apply or not apply to the Maghreb. The empirical approach consists of taking measurements that reflect gender standards and democratic standards across the three countries and four different milestones of their recent history (1970, 1980, 1990, 2000), and applying statistical methods to compute correlations and regressions. Because the empirical approach yields no significant correlation between gender standards and democratic standards in the Maghreb, I analyze this statistical correlation for other sets of countries that are part of Maghrebian identity: Arab countries, Muslim countries, African countries, and Mediterranean countries. The combined results of these analyses give us some insight into possible explanations of the empirical observations.Ph.D.Includes bibliographical references (p. 261-275)by Amel Mil
Hicri ilk iki asırda farklı şehirlerde amel telakkisi oluşumunda sünnet ve hadisin yeri
No full textHİCRİ İLK İKİ ASIRDA FARKLI ŞEHİRLERDE AMEL TELAKKİSİ OLUŞUMUNDA SÜNNET VE HADİSİN YERİ Bu tezde, hicri ilk iki asır boyunca farklı anlayışların temsil edildiği büyük ilim merkezlerindeki (emsâr) fukahânın amel telakkileri ele alınmaktadır. Tezin temel argümanı, amel anlayışının sadece Medine’ye has olmadığı, o dönemin diğer ilim merkezlerinde de kendilerine mahsus birer amel anlayışının oluştuğu ve bu anlayışların, hüküm istinbatı sürecinde fukaha tarafından dikkate alındığı iddiasıdır. Tezde öncelikle klasik ve modern literatürde amel meselesi ele alınmakta, ardından ikinci asırdaki şehirlerin amelleri (amelü’l-emsâr) işlenmekte, son olarak da ikinci asırdaki büyük ilim merkezlerini temsil eden fakihlerin (fukahâü’l-emsâr) amel anlayışları ve amel tartışmalarına yer verilmektedir. AMAL UNDERSTANDINGS OF THE FUQAHA AL-AMSAR AT THE SECOND CENTURY OF THE HIJRAH In this dissertation, ‘amal understandings of the famous and representative scholars (fuqahā al-amsār) at the second century of the Hijrah are scrutinized. The author mainly focuses on the fact that all of the big centers of the second century after the hijrah (al-Amsār) has its own understanding of ‘amal and, contrary to what is generally accepted, such an understanding is not unique to Madina. The author reviews the literature on the amal firstly, elaborates on the understandings of big centers at that time secondly, then focuses on the debates about the issue among some famous fuqahā in each center, namely Mālik b. Anas from Madina, Muhammad b. al-Hasan al-Shaybānī from Kufa, and al-Awzāī from Syri
Pregnancy and breastfeeding: a new theory for sHLA-G in breast cancer patients?
No full textConcerns about breast cancer (BC) etiology have increased studies aboutresearches on the the implication of HLA-G molecules in thissuch malignancy. HLA-G molecules act as immune-inhibitory mediators that could promote tumor growth. In this study, we investigated the levels of sHLA-G in plasma samples from women patients withaffected by BC and cor-related them with regarding theirprevious pregnanciesy, or breast-feeding experience as well as their menopause status.
We report, for the first time, a significant differences in sHLA-G levels in between BC patients without breast-feeding experience and those who have breastfed (p=0.04). Simi-larly, sHLA-G is significantly increased in BC patients without previous pregnancy experi-ence compared to those who have had this experiencebeen pregnant (p=0.02). No differences in sHLA-G levels were noticed when we comparedbetween premenopausal and postmeno-pausal BC patients.
Additionally, we demonstrated that patients having not been pregnant and who have not breastfed have morepresented an increased advanced SBR III grade, associated to with significant enhancement in tumor size compared to with patients who have had both experi-ences (p=0.028). These later patients have also more expressed higher levels ofion of proges-terone and estrogen receptors with an increased chance to be responsive to giving them prob-ably more good response to hormonal therapies.
Taken together, our results indicate the probable possible implication of breast-feeding and pregnancy in HLA-G expression during BC and in the protection against complicated stages of BC
Serial Mediation Of Perceived Usefulness And Ewom Adoption In Virtual Communities And The Moderating Effect Of Gender
No full textPurpose – This study analyzes the adoption behavior of eWOM information from the consumer’s
perspective. In virtual communities, this study examines the serial mediation of perceived
usefulness and adoption of eWOM between eWOM characteristics (credibility, quality, and
vivacity) and the intention to visit a tourist destination and gender as a moderator. This study
makes a significant theoretical and practical contribution by the purpose of an integrative
model, according to the ELM model, and by examining the moderating effect of gender.
Design/Methodology/Approach – This study tests the hypothesis using an experimental
scenario simulation method. Signals embedded in various components of the eWOM (stimuli/
scenarios) were used, such as interactivity with the message (Like number, comment, sharing)
or the content of the message (Text, Visual, Video). The new model (based on the ELM
model) was validated by PLS-SEM based on an online survey of 548 members of the virtual
consumption communities where content shared is about tourism and hospitality, tourism
experiences, and recommendations of Algerian tourist destinations.
Findings – The results confirm that perceived usefulness and adoption are two serial mediators
between the relationship between eWOM characteristics and visit intention. Finally, gender
moderates the indirect effect between eWOM quality and the intention to visit.
Originality of the research – This study proposes to develop an integrative model by testing
the serial mediating effects of perceived usefulness and information adoption for the first
time regarding the influence of the three eWOM characteristics on behavioral intention and
investigates the role of gender as a moderato
Le régime alimentaire du Pigeon ramier Columba palumbusaux abords de la plaine de la Mitidja (Nord Algérie)
No full textDiet of the Wood Pigeon Columba palumbus near the plain of Mitidja (northern Algeria)
From March 2006 to May 2007, we studied the diet of the Wood Pigeon Columba palumbus in forest and suburban area near the Mitidja plain (northern Algeria). The species appears almost exclusively phytophagous, 26 of the 35 food items inventoried are of plant origin. The analysis of 36 stomach contents in forest shows that it is mainly granivorous in spring, and consumes 96.2 % of Oxalis pes-caprea seeds against 3.2 % for animals (Gastropods and Crustaceans). In autumn and winter, the plants constitute 100 % of the diet, dominated with 99.7 % by olives. The Wood Pigeon behaves in this site as an opportunistic species. Direct observations in suburban area indicate the exclusive consumption of 15 plant species with a clear preference for Fraxinus angustifolia (54.9 %). As a whole, 50 % of plants are searched for their seeds and 42.3 % of food items come from agricultural production. Near the Mitidja, the diet, almost exclusively phytophagous of the Wood Pigeon, consists essentially of plants different from those known in Europe, and the species appears to be opportunistic in forest but at the same time specialist in suburban areas.Une étude du régime alimentaire du Pigeon ramier Columba palumbus a été réalisée de mars 2006 à mai 2007 sur deux sites, l’un forestier et l’autre suburbain, situés aux abords de la plaine de la Mitidja (Algérie). L’espèce apparaît presque exclusivement phytophage, 26 des 35 items alimentaires inventoriés étant d’origine végétale. L’analyse de 36 contenus stomacaux en forêt montre que l’espèce est essentiellement granivore au printemps, consommant 96,2 % de graines d’Oxalis pes-caprea contre 3,2 % pour les animaux (Gastéropodes et Crustacées). En automne et hiver, les végétaux constituent 100 % du régime alimentaire, dominé à 99,7 % par des olives. Le Pigeon ramier se comporterait dans ce site en espèce opportuniste. Les observations directes en milieu suburbain indiquent l’utilisation exclusive de 15 espèces végétales avec une préférence marquée pour Fraxinus angustifolia (54,9 %). Dans l’ensemble, 50 % des végétaux sont recherchées pour leurs graines et 42,3 % des items alimentaires sont issus de la production agricole. Aux abords de la Mitidja, le régime du Pigeon ramier est essentiellement constitué par des végétaux différents de ceux que l’on connaît en Europe, et l’espèce est apparue à la fois opportuniste en forêt et spécialiste en milieu suburbain.Merabet Amel, Chebouti-Meziou Nadjiba, Chebouti Yahia, Bissaad Fatima-Zohra, Doumandji Salaheddine.

in ovarian carcinoma
No full textHLA-G is a non-classical major histocompatibility complex class Ib molecule. Its expression has been described in various cancer types, including ovarian cancer. HLA-G molecule has been implicated in immune escape and in progression of ovarian tumor cells. Our goal was to assess if total soluble (s)HLA-G molecules or HLA-G5 and sHLA-G1 isoforms could be considered as circulating ovarian tumor biomarkers, we measured the concentration of these molecules in ovarian carcinoma patients stratified according with their clinicopathological parameters. sHLA-G, sHLA-G1 and HLA-G5 concentrations were dosed in plasma samples by sandwich-ELISA. The sHLA-G dimerization was analyzed after immunoprecipitation and SDS-PAGE migration. Total sHLA-G and sHLA-G1 levels were significantly represented in plasma of ovarian carcinoma patients compared to healthy controls. sHLA-G1 isoform concentration was highly represented in ovarian carcinoma compared to HLA-G5 isoforms. Additionally, high sHLA-G molecules have been found in aged patients, as well as in patients with advanced stages, and those with metastatic lymph nodes and those with distant metastasis. Elsewhere, sHLA-G monomers were highly represented in ovarian carcinoma patients compared to controls. sHLA-G plasmatic protein was highly represented in ovarian carcinoma. In effect, HLA-G might be considered as a new checkpoint molecule that could be used to assess progression and recurrence of the disease, thus placing it as a potential biomarker for advanced and complicated ovarian carcinoma
Asymmetric transmission of monetary policy through interest rate, credit volumes and exchange rate channels Using Nonlinear Autoregressive Distributed Lags (NARDL) method: Evidence from Algeria
No full textThis article aims to study the effectiveness and symmetry of the transmission of monetary policy in Algeria through the channels of interest rates, credit, and exchange rates in both the short and long term, using the Nonlinear Autoregressive Distributed Lag (NARDL) method. The study of asymmetric effects of monetary policy channels on both output and prices stability is of paramount value for monetary policy analysis and implementation. The results have shown that the transmission of monetary policy in Algeria exhibits an asymmetric nature, except for the effect of bank lending interest rates on real gross domestic product and inflation and that the traditional interest rate channel is the most effective in transmitting the effects of monetary policy to real gross domestic product, while positive variations in credit volume are most effective in the long term, and negative changes in the exchange rate are the most efficient in the short-term concerning the transmission to inflation

Effets du sentiment communautaire virtuel sur la fidélité
No full textLe Sentiment Communautaire Virtuel, qui décrit la force des liens entre les membres d’une communauté virtuelle, est un concept relativement nouveau dont peu est réellement connu. L’objectif de cette recherche est double. D’abord, une échelle de mesure en français est proposée. Celle-ci repose sur le travail de Koh et Kim (2003). Ensuite, son influence sur la fidélité à l’entreprise est explorée. À partir d’une collecte de données de 342 membres, les résultats montrent que le sentiment communautaire virtuel favorise directement la fidélité. Toutefois, il affaiblit les liens entre la qualité de la relation client et la fidélité.The sense of virtual community is defined as the sense of being tied to the group. It is relatively a new concept that needs more exploration. First, this research develops a French scale measure for it. The latter relies on the scale measure of Koh and Kim (2003). Second, its influence on loyalty is explored. Data from 342 members of company-managed virtual communities have been collected. Results show that the sense of virtual community favours loyalty. However, it makes weaker the influence of the relationship quality on loyalty.El Sentimiento de la Comunidad Virtual, que describe la fuerza de los lazos entre los miembros de una comunidad virtual es un concepto relativamente nuevo y se conoce realmente poco. El objetivo de este trabajo es doble. En primer lugar, se propone una escala de medida en francés. Se apoya en la obra de Koh y Kim (2003). Luego se explora su influencia en la fidelidad hacia la empresa. Se colectaron datos de 342 miembros, los resultados muestran que el sentimiento comunidad virtual favorece directamente la fidelidad. Sin embargo, debilita los vínculos entre la calidad de las relaciones con los clientes y la fidelidad
Exploration Des Compétences Nécessaires à L’activité De Traversée De La Rue Et Risques D’accident Chez Le Piéton
No full textتهدف هذه الدراسة إلى الكشف عن دور المهارات السلوكية في نشاط عبور الطريق وعلاقتها بالتعرض لحوادث الراجل. يعتبر هذا النشاط نوعا من حل المشكلات، ويستخدم الراجل مهارات محددة والمتمثلة في تصور عبور موقع، وتحليل معلومات عن حركة المرور، تقدير الوقت اللازم لعبور الطريق، وتوقع سلوك السائق. شملت عينة الدراسة 115 فردا (54 أنثى و 61 رجلا) و تراوحت أعمارهم بين 18 و 60 سنة. قسمت هذه العينة إلى أربع مجموعات فرعية حسب السن، وإلى ثلاث مجموعات حسب المستوى التعليمي (الأساسي والثانوي والجامعي). واستعمل سلم المهارات السلوكية لعبور الطريق، وتقدير عدد مرات تعرض الفرد للدهس حسب ما يقر به الفرد. أظهرت النتائج أن الخصائص السيكومترية للاختبار مقبولة. بينت نتائج تحليل التباين أن هناك علاقة سلبية بين درجة المهارات السلوكية وعدد المرات التي تعرض فيها الراجل لخطر الدهس (ر = -0.30،P ≤ 0.01) ) و بينت نتائج تحليل الانحدار الخطي أن المهارات السلوكية لعبور الطريق تنبئ بانخفاض خطر التعرض للدهس عند الراجلين (β=- 0.30 ، ت= - 3.29، دالة عند مستوى أقل من 0.001). كما أظهرت نتائج الدراسة وجود فروق تعزى للمستوى الثقافي وهي لصالح المجموعة الفرعية من ذوي التعليم الجامعي (ف (2، 112)= 3.419، قيمة الدلالة) ، بينما لا توجد فروق تعزى لمتغير السن (ف (3 ، 111)= 2.071، قيمة الدلالة قيمة الدلالة = 0.108) وكذلك حسب الجنس (ت= 0.69 ، قيمة الدلالة = 0.49). تبين هذه النتائج أن سلم المهارات السلوكية لعبور الطريق يمكنه تقدير هذه المهارات. لذلك، يمكن اعتماد محدداته في عملية التحسيس ونشر الوعي في البيئة الاجتماعية والتعليمية لاكتساب واستيعاب المهارات السلوكية الجيدة للحد من مخاطر تعرض الراجل للحوادث.La présente étude explore le rôle des compétences nécessaires à l’activité de traversée de la rue et leurs relations avec l’exposition aux risques d’accidents chez l’usager piéton. Cette activité s’apparente à une tâche de résolution de problème pour laquelle les piétons doivent utiliser des compétences spécifiques reconnu dans l’ensemble de la littérature dédiée à la question : « la perception du site de traversée, l’analyse de l’information routière, l’estimation du temps nécessaire à la traversée, et l’anticipation du comportement du conducteur. Un échantillon de 115 personnes (54 femmes, 61 hommes) ont répondu au test des Habilités comportementales de traversée de la rue (HCTR). Cet échantillon est composé de quatre sous groupes d’âges (G1: 18-30 ans ; G2: 31-40ans ; G3: 41-50 ans ; G4 : 51-60ans) et de niveau d’instruction fondamental, secondaire et universitaire. Les résultats montrent que les propriétés psychométriques du test sont acceptables. En revanche l’analyse des données montre l’existence d’une corrélation négative entre les compétences mesurées par le HCTR et le nombre de fois dans lesquelles le piéton a été victime d’accident (r=-0.30, p ≤ 0.01). La régression linéaire simple révèle que l’élévation du score dans le HCTR prédit la diminution des risques d’accidents des piétons (β = - 0,30, t = -3,29, p< 0,001). Le One way ANOVA montre que les scores du HCTR sont plus élevés chez le sous groupe de niveau d’instruction universitaire à comparer avec les deux autres niveau d’instruction ( F(2, 112)= 3.419, p= 0.036), cependant, aucune différence significative est révélée en fonction des variables tranche d’âge ( F(3, 111)= 2,071, p= ,108) et sexe (t= .69 , p= .49) Ces résultats montre que l’échelle des HCTR développée dans cette étude peut être mieux formulé afin de mesurer plus d’habilitées comportementales opérantes et sécurisantes chez les piétons. Par conséquent, cela implique que la sensibilisation dans le milieu socio-éducatif est la base d’acquisitions et d’assimilation des bonnes habilités comportementale pour diminuer les risques d’accidents
