Abstract This study was undertaken to examine traditional forms of literacy and the newest form of literacy: technology. Students who have trouble reading traditional forms of literacy tend to have lower self-esteem. This research intended to explore if students with reading difficulties and, therefore, lower self-esteem, could use Social Networking Technologies including text messaging, Facebook, email, blogging, MySpace, or Twitter to help improve their self-esteem, in a field where spelling mistakes and grammatical errors are commonplace, if not encouraged. A collective case study was undertaken based on surveys, individual interviews, and gathered documents from 3 students 9-13 years old. The data collected in this study were analyzed and interpreted using qualitative methods. These cases were individually examined for themes, which were then analyzed across the cases to examine points of convergence and divergence in the data. The research found that students with reading difficulties do not necessarily have poor self-esteem, as prior research has suggested (Carr, Borkowski, & Maxwell, 1991; Feiler, & Logan, 2007; Meece, Wigfield, & Eccles, 1990; Pintirch & DeGroot, 1990; Pintrich & Garcia, 1991). All of the participants who had reading difficulties, were found both through interviews and the CFSEI-3 self-esteem test (Battle, 2002) to have average self-esteem, although their parents all stated that their child felt poorly about their academic abilities. The research also found that using Social Networking Technologies helped improve the self-esteem of the majority of the participants both socially and academically.

Les pratiques religieuses dans les pays de l’Atlantique Nord se transforment et on observe pour une partie de leur population le passage d’un « croire institutionnalisé » à une spiritualité influencée par diverses traditions, dont certaines ont fait leur apparition sur ce territoire au milieu du 20e siècle. Le présent mémoire vise à mettre en lumière une des facettes de la diversité religieuse contemporaine; suite aux questionnements qui ont surgi au long du travail, il aborde aussi certains enjeux sous-jacents à l’analyse d’un groupe religieux en anthropologie, notamment comment aborder le terrain et comment considérer un tel groupe. J’ai choisi pour ce faire de décrire un groupe religieux québécois qui est lié à un culte afro-brésilien – l’umbanda– et qui est membre d’un réseau transnational de temples. J’examinerai d’abord comment l’umbanda s’est développée au Brésil, car cela fournira des indications pertinentes sur, entre autres choses, l’éventuelle perméabilité de cette tradition, une fois le groupe implanté dans un pays de l’Atlantique Nord. J’examinerai ensuite le type de transnationalisation qui a présidé à la naissance du temple à Montréal, car cette analyse offre des indices permettant de déterminer comment un tel groupe s’insère dans le paysage religieux de divers pays. Enfin, en me penchant sur les pratiques religieuses des membres du groupe, je tenterai de dégager certaines particularités locales.

A novel compact RFID tag employing open stubs in a microstrip transmission line is proposed. The prototype of the tag is fabricated on a substrate of dielectric constant 4.4 and loss tangent 0.0018. The tag consists of microstrip open stub resonators and cross polarized transmitting and receiving disc monopole antennas. A prototype of 8 bit data encoded tag is demonstrated in this communication. Method for enhancing the performance of the RFID tag is also proposed. Magnitude or group delay response can be used to decode the tag informations

Reproductive morphology of the Mediterranean red alga Kallymenia patens is described for the first time, confirming its position in the genus. K. patens is characterized by a non-procarpic female reproductive apparatus, carpogonial branch systems consisting of supporting cells bearing both three-celled carpogonial branches and subsidiary cells that lack a hypogynous cell and carpogonium; fusion cells develop numerous connecting filaments, and tetrasporangia are scattered over the thallus and are probably cruciately divided. Old fertile spathulate specimens of K. patens are morphologically similar to K. spathulata, but they can be distinguished by the length of spathulated proliferations (up to 0.6 cm and 6 cm, respectively), the length of inner cortical cells (up to 70 and 30 μm, respectively), and the gonimoblast location (in proliferations from the perennial part of the blade and over all the thallus surface, respectively)

Dadas las relaciones de cooperación internacional que presentan las Repúblicas de Colombia y Corea que se evidencia en los fuertes vínculos comerciales existentes entre las dos naciones y aún más en la negociación de un TLC desde el 2009 y gracias al buen clima económico que presenta en la actualidad Colombia, surge este proyecto de investigación con el objetivo de analizar las relaciones bilaterales y contribuir al desarrollo de la economía emergente que presenta el país. Para ello, en primera instancia se realiza un proceso de contextualización desde aspectos demográficos hasta históricos. En seguida y a manera descriptiva, se expone los diversos bienes y servicios que se intercambian entre las dos naciones con el fin de identificar oportunidades que se podrían ofrecer y afectar una vez se firme el tratado. Finalmente, se evalúa y analiza cada uno de los sectores emergentes de Colombia con el objeto de motivar la inversión en el país para generar de tal manera, un incremento en la producción y por ende incrementos en la demanda agregada, logrando abrir las puertas de la economía colombiana a un socio estratégico como lo es la República de Corea y contribuir poco a poco a la reducción de la balanza comercial deficitaria que se presenta en la actualidad entre los dos países. Términos clave: Relaciones internacionales, Corea, oportunidades, economía, relaciones comerciales.
