The Impact of Four Reading Motivational Constructs on Motivating EFL Learners to Read Online Texts in English
Authors: Al Seghayer Khalid 
Published: September 2013

It is generally acknowledged that motivation plays a critical role in second-language (L2) reading. The technology-enhanced learning environment, specifically the computer-assisted reading environment as an interactive tool with distinctive attributes, is said to motivate English as a foreign language (EFL) learners to make more sustained efforts in online reading and show greater perseverance. Such an environment encourages students to devote more time to reading due to its ability to more profoundly engage English learners in reading accessible, electronic English texts. The present study investigates the relative contribution of four motivational constructs that constitute the EFL learner’s online reading motivation: the intrinsic value of reading online English texts, the extrinsic value of reading online English texts, the attainment value of reading, and reading efficacy. The study closely measures the views of EFL learners in preparatory programs at selected Saudi universities regarding the value of online reading with respect to these four motivational constructs. In addition, it explores differences in these motivational constructs according to the perspectives of both genders who are attending preparatory programs, as well as examines the motivational attitude of EFL learners toward the value of reading online English texts. A 35-item survey was administered to the selected respondents to identify the four dimensions of EFL learners’ online English reading motivation. The findings indicate that the four online reading motivational constructs contribute positively to EFL learners reading online English texts in the following order: extrinsic, attainment, intrinsic, and efficacy. The questionnaires were analyzed by use of within- and between-subjects ANOVA and post-hoc pairwise comparisons, whereas the open-ended questions were analyzed by use of content analysis. The results also show that both male and female EFL learners have high motivation to read online English texts, with female learners scoring significantly higher than male learners on the attainment scale.A thorough discussion that incorporates the present results is provided, along with proffering and highlighting practical technical and pedagogical implications for computer-assisted language learning (CALL) reading classrooms beyond the given context. Areas of potential future research are delineated as well.
Congruence Relations for Shimura Varieties Associated withGU(n–1, 1)

Published: September 2013

AbstractWe prove the congruence relation for the mod–preduction of Shimura varieties associated with a unitary similitude groupGU(n– 1, 1) over ℚ whenpis inert andnodd. The case whennis even was obtained by T. Wedhorn and O. Bültel, as a special case of a result of B. Moonen, when theμ–ordinary locus of thep–isogeny space is dense. This condition fails in our case. We show that every supersingular irreducible component of the special fiber of p–ℐsog is annihilated by a degree one polynomial in the Frobenius elementF, which implies the congruence relation.
Contemporary Issues in Clinical Dental Teaching
Authors: Groenlund Catherine , Handal Boris 
Published: September 2013

ABSTRACT

Aim
This research project sought to explore the issue of what constitutes effective clinical teaching in the minds of both students and teachers.

Background
As stakeholders of the dental clinical setting, teachers and students have valuable practical insights to share with the academic and professional community as to what constitutes effective dental teaching.

Case description
An explorative qualitative study of dental teachers’ and students’ perceptions of clinical teaching was carried out at the Faculty of Dentistry of Sydney University. Thirty-one clinical teachers and 12 students participated in this case study through an online questionnaire survey and a focus group, respectively. Responses were categorized in three major clusters, namely, instructional, curricular or organizational.

Conclusion
The findings reveal that both groups hold similar opinions on what constitutes effective clinical instruction including a shared passion for learning and teaching, being clear and organized, demonstrating clinical competencies as well as engaging in professional self-reflection. Most of the issues fell into the instructional cluster where establishing a positive relationship with students including providing constructive feedback at the clinical session came up as key factors contributing to the student experience.

Clinical significance
There is a demand from both students and teachers to standardize clinical procedures and protocols as well as having a greater synchronization in time and content between lectures and clinical work.

Attitude of General Dental Practitioners toward Root Canal Treatment Procedures in India
Authors: Bhondwe Sarvesha , Jain Deepak , Gaikwad Ashwini , Rane Prasad , Doshi Saurabh 
Published: September 2013

ABSTRACT

Objective
The percentage of general dental practitioners is very common in India, so the purpose of this study was to assess attitude of general dental practitioners toward root canal treatment (RCT) procedures.

Materials and methods
In a cross-sectional study, 178 dentists (96 males and 82 females) were surveyed using a selfadministered, structured questionnaire pretested through a pilot survey. The questionnaire collected information regarding RCT procedures among participants. Data were analyzed using SPSS version 15. Frequency and percentage distributions were calculated.

Results
In the present study most of the participants, i.e. 86.4% reported that they perform (RCT) procedures in posterior teeth. Isolation is mainly done with cotton rolls only (74.6%) and very few are using rubber dam in their practice (3.2%). Radiographs were not taken after every step in most of the cases. Rotary instruments were used in less number of cases and K-files were the most popular instruments (66.2%). Also single sitting RCT was not commonly seen.

Clinical significance
This study indicates that most of the general dental practitioners’ do not comply with quality standards guidelines such as use of rubber dam as isolation. So dentist should update their knowledge and practices with current techniques and materials through CDE programs.

Johanson-Blizzard Syndrome: Dental Findings and Management
Authors: Santhosh BP , Jethmalani Preeti 
Published: September 2013

ABSTRACT

Aim
Oral rehabilitation of a child with Johanson-Blizzard syndrome (JBS).

Background
JBS is an extremely rare inherited disorder characterized by unusually small nose that appears ‘beak shaped’ due to the absence (aplasia) or underdevelopment (hypoplasia) of the nostrils (nasal alae), abnormally small, malformed primary (deciduous) teeth and misshapen or absent secondary (permanent) teeth, hearing disorder, hypothyroidism, dwarfism, malabsorption and mental retardation. It is sometimes described as a form of ectodermal dysplasia.

Case report
Oral findings in JBS are very obscure in the literature. The present report describes oral findings in an 8 years old boy with JBS and his oral rehabilitation.

Conclusion
JBS has an emotional consequence for the affected individuals at early ages. Oral rehabilitation in this case had a very positive impact on the child's mind.

Clinical significance
Early identification and treatment of this disease is of great importance to rehabilitate the patient on functional, esthetic and psychological front.

Ameloblastic Fibrodentinoma: Report of a Rare Case
Authors: Salehinejad Jahanshah , Langaroodi Adineh Javadian , Shahakbari Reza , Yazdani Neda 
Published: September 2013

ABSTRACT

Aim
This is to report a rare case of ameloblastic fibrodentinoma (AFD), including detailed history, histopathologic as well as radiographic findings. Her condition, a mixed odontogenic tumor, has rarely been reported in publications. We also included the gist of theories put forward regarding the histogenesis of this lesion.

Background
AFD is a rare and controversial entity; it boasts a variety of classifications and terminology based on its unique biological nature as well as histopathological features.

Case description
The patient was a 13-year-old girl with a chief complaint of central unerupted tooth on the left mandible. Cone beam computed tomographic images revealed a mixed pericoronal and multilocular lesion surrounding the crown of the aforementioned tooth, displacing it apically to a large extent.

Conclusion
It is important to differentiate AFD from other benign mixed odontogenic tumors with similar radiographic appearance because of different therapeutic approaches in some of these tumors.

Clinical significance
From the clinical point of view, it is of paramount significance for dental practitioners to assess any delayed tooth eruption (more than 6 months and in comparison with its counterpart on the opposite side) radiographically to ascertain or rule out any such similar lesions.

Preoperative Gingival Conditioning as a Guide for Implant Installation and to achieve Proper Dentogingival Contours
Authors: Tonetto Mateus Rodrigues , Bandéca Matheus Coelho , de Jesus Tavarez Rudys Rodolfo , Malheiros Adriana Santos , Benatti Bruno Braga 
Published: September 2013

ABSTRACT
A successful esthetic outcome for implant-supported dentures depends on the careful manipulation of peri-implant tissue as well as the precise placement of the implant. In addition, careful surgical and prosthetic planning is essential for esthetically important areas, especially in partially edentulous cases. This study describes a clinical case that presented absent maxillary central incisors in which prior prosthetic planning was used to perform provisional restorations, that was used to condition the gingival tissues and guide implant installation. These procedures made it possible to achieve a dentogingival contour, interdental papillae, and an emergence profile in the edentulous area. The techniques outlined here proved to be sufficient and support the peri-implant tissues to create a more esthetic final prosthesis.

Published: September 2013

ABSTRACTAimThe aim of this study is to evaluate through a literature review, the soft tissue response in contact with zirconia abutments, including case reports comparing prosthetics rehabilitations with zirconia and titanium abutments upto 3 years of follow-up as well as the factors that should be considered on implant's abutment selection.BackgroundMetallic abutments can provide grayish color when in contact with thin soft tissues which may lead the implant prosthetic treatment to failure. In this context, the abutments of zirconia stand out because there is an excellent linking between esthetics and the health of peri-implant soft tissues.Materials and methodsA consult of the published researches was made on the PubMed database from 2000 to September 2012. The including criteria were: literature reviews, clinical studies and case reports in English that focused on the response of the soft tissue in contact with zirconia implant abutments. The studies that were not in English and did not match the tackled issue were excluded.ResultsA total of 32 articles were found. According to the search strategy, just 16 articles were selected for this review. Three studies affirmed that zirconia abutments have an excellent soft tissue response; one study showed increased gingival recession with zirconia abutments and nine studies do not stand out any difference on biological behavior between titanium and zirconia abutments. Three studies affirmed that zirconia abutments provide natural gingival appearance, anatomic contour and greater esthetics.ConclusionThe use of zirconia abutments is recommended for anterior regions because of their greater optical properties and esthetic results and more studies should be performed and analyzed longitudinally regarding their biological response.Clinical significanceThe zirconia abutments have been established to be essential in order to achieve great esthetic results in cases of thin peri-implant soft tissues and in regions where the three-dimensional placement of implants is more superficial.How to cite this articlede Medeiros RA, Vechiato-Filho AJ, Pellizzer EP, Mazaro JVQ, dos Santos DM, Goiato MC.

Contribuciones de Zamorano a la Investigación y Proyección en el Manejo de Cuencas en Centro América
Authors: Caballero B. Luis A. 
Published: September 2013

El agua es el bien y servicio ecosistémico más valorado por las poblaciones rurales y urbanas. Dada su importancia en la vida cotidiana del ser humano, el agua y las cuencas presentan oportunidades únicas para promover un modelo de manejo integrador, incluyendo lo ambiental, socioeconómico e institucional. Es en la cuenca donde el interés individual de usufructuar la tierra para beneficio y ganancia personal y familiar, tiene que sopesarse con el interés público de obtener agua de calidad, en cantidad apropiada y con regularidad. Hay zonas en las cuencas en donde la protección y conservación del bosque es imprescindible para la producción y provisión sostenida de agua. En los últimos 18 años, el programa de manejo de cuencas de Zamorano, con apoyo financiero de varios entes nacionales e internacionales, ha contribuido a la protección de los recursos naturales en importantes cuencas de la región. El programa ha también beneficiado miles de familias mediante la reconstrucción y construcción de sistemas de agua para riego agrícola y consumo humano. Miles de jóvenes rurales fueron capacitados e involucrados en la protección de los recursos naturales y actividades de desarrollo local. Además, centenas de jóvenes latinoamericanos se han graduado de Zamorano, y están hoy día activamente involucrados en manejo de cuencas, la protección de los recursos naturales y el desarrollo rural a través de Latino América. La investigación aplicada, desarrollada por profesores y estudiantes de la Carrera de Desarrollo Socioeconómico y Ambiente (DSEA), permitió conocer mejor los escenarios de trabajo. Esto ayudó a la planificación e implementación de acciones más precisas y efectivas, y a monitorear y evaluar los programas y proyectos. La contribución de Zamorano al avance de la ciencia hidrológica en el trópico incluye el diseño y construcción de dos sitios de investigación que son cuencas experimentales: Capiro-Zapotillo y el Parque Nacional la Tigra. Todos estos programas y proyectos han contribuido muchoa las comunidades rurales y a la sociedad en general.DOI: http://dx.doi.org/10.5377/ceiba.v52i1.974
Determination of Yohimbine in Yohimbe Bark and Related Dietary Supplements Using UHPLC-UV/MS: Single-Laboratory Validation
Authors: Chen Pei , Bryden Noella 
Published: September 2013

Abstract
A single-laboratory validation was performed on a practical ultra-HPLC (UHPLC)-diode array detector (DAD)/tandem MS method for determination of yohimbine in yohimbe barks and related dietary supplements. Good separation was achieved using a Waters Acquity ethylene bridged hybrid C18 column with gradient elution using 0.1% (v/v) aqueous ammonium hydroxide and 0.1% ammonium hydroxide in methanol as the mobile phases. The method can separate corynanthine from yohimbine in yohimbe bark extract, which is critical for accurate quantitation of yohimbine in yohimbe bark and related dietary supplements. Accuracy of the method was demonstrated using standard addition methods. Both intraday and interday precisions of the method were good. The method can be used without MS since yohimbine concentration in yohimbe barks and related dietary supplements are usually high enough for DAD detection, which can make it an easy and economical method for routine analysis of yohimbe barks and related dietary supplements. On the other hand, the method can be used with MS if desired for more challenging work such as biological and/or clinical studies.
La densification urbaine dans le quartier Vanier : germe d’un renouveau urbain ou menace pour le dernier îlot francophone de la capitale canadienne ?
Authors: Benali Kenza 
Published: September 2013

Petite cité ouvrière au XVIIIe siècle, le quartier Vanier est aujourd’hui un centre urbain dynamique, intégré à la municipalité d’Ottawa dont il bénéficie du développement économique, tout en s’affichant comme le principal bastion francophone et creuset de la culture franco-ontarienne de la capitale. Toutefois, le quartier vit une réalité à deux vitesses : demeurant un des espaces les plus défavorisés d’Ottawa, en lien avec son passé ouvrier, il connaît depuis peu une relance économique, touristique et immobilière sans précédent, qui n’est pas sans poser un défi identitaire à ses résidants. Face aux intentions louables des tenants du développement durable prônant la densification du secteur, comment lutter pour la préservation des spécificités culturelles de Vanier, quartier typiquement canadien-français dans un paysage sociospatial à dominante anglophone ? Le renouveau urbain se ferait-il en vérité au bénéfice d’une nouvelle population, plus aisée, venue s’implanter à Vanier avec les dernières grandes opérations d’aménagement ? Dans cet article, nous nous proposons, dans le cadre d’une monographie du quartier et d’un conflit urbain y ayant pris place, de revenir sur les arguments identitaires, relayés ici par la presse écrite, mobilisés pour faire barrage à un projet de densification urbaine.
Artisanat traditionnel, valorisation touristique du patrimoine et dynamique territoriale : le cas de la ville syrienne d’Alep
Authors: Ferguene Améziane , Banat Rabih 
Published: September 2013

Rédigé un peu avant le début des événements dramatiques qui ravagent la Syrie depuis mars 2011, cet article analyse la relation entre ressources territoriales et développement touristique dans la ville d’Alep. Adoptant la perspective historique longue, il expose dans un premier temps la mutation de ce vieux territoire urbain dont l’économie, jusque-là fondée largement sur l’artisanat traditionnel, a été engagée, au cours des années 2000, dans un processus de diversification par intégration du tourisme comme voie complémentaire de mise en valeur de son riche patrimoine culturel. Dans un deuxième temps, l’analyse se focalise justement sur le rôle des ressources patrimoniales dans le développement socioéconomique de cette ville. La conclusion à laquelle aboutit la réflexion est que, dans le contexte actuel de concurrence globalisée entre pays et territoires, l’avenir d’Alep dépend en bonne partie de la capacité des autorités locales et du gouvernement central à imaginer un mode de gouvernance capable de mobiliser tous les acteurs autour d’un projet collectif de développement territorial. Il va sans dire que le conflit armé que vit la Syrie depuis plus de deux ans maintenant, et qui a détruit (en partie) ses institutions, est de nature à compromettre cette analyse. Toutefois, compte tenu du rapport des forces en présence, il n’est pas exclu qu’une solution politique, satisfaisante pour tous, soit trouvée dans un avenir proche. Pour peu que cette solution prévoie une dose d’autonomie des régions par rapport au pouvoir central, les acteurs locaux d’Alep auront à coeur de relancer sur des bases rénovées la dynamique de développement territorial. Dans une telle hypothèse (favorable), l’analyse esquissée ici retrouverait alors toute son actualité.
Comparison of point‐of‐care versus laboratory‐based CD4 cell enumeration in HIV‐positive pregnant women
Authors: Myer Landon , Daskilewicz Kristen , McIntyre James , Bekker Linda‐Gail 
Published: September 2013

IntroductionEarly initiation of antiretroviral therapy (ART) in eligible pregnant women is a key intervention for prevention of mother‐to‐child transmission (PMTCT) of HIV. However, in many settings in sub‐Saharan Africa where ART‐eligibility is determined by CD4 cell counts, limited access to laboratories presents a significant barrier to rapid ART initiation. Point‐of‐care (POC) CD4 cell count testing has been suggested as one approach to overcome this challenge, but there are few data on the agreement between POC CD4 cell enumeration and standard laboratory‐based testing.MethodsWorking in a large antenatal clinic in Cape Town, South Africa, we compared POC CD4 cell enumeration (using the Alere PimaTM Analyzer) to laboratory‐based flow cytometry in consecutive HIV‐positive pregnant women. Bland–Altman methods were used to compare the two methods, including analyses by subgroups of participant gestational age.ResultsAmong the 521 women participating, the median gestational age was 23 weeks, and the median CD4 cell count according to POC and laboratory‐based methods was 388 and 402 cells/µL, respectively. On average, the Pima POC test underestimated CD4 cell count relative to flow cytometry: the mean difference (laboratory test minus Pima POC) was 22.7 cells/µL (95% CI, 16.1 to 29.2), and the limits of agreement were −129.2 to 174.6 cells/µL. When analysed by gestational age categories, there was a trend towards increasing differences between laboratory and POC testing with increasing gestational age; in women more than 36 weeks’ gestation, the mean difference was 45.0 cells/µL (p=0.04).DiscussionThese data suggest reasonable overall agreement between Pima POC CD4 testing and laboratory‐based flow cytometry among HIV‐positive pregnant women. The finding for decreasing agreement with increasing gestational age requires further investigation, as does the operational role of POC CD4 testing to increase access to ART within PMTCT programmes.
