En septiembre de 2015, los Estados Miembros de las Naciones Unidas deberán comprometerse con un nuevo conjunto de ambiciosos objetivos mundiales para una nueva era de desarrollo sostenible. Lograr dichos objetivos requerirá un esfuerzo conjunto sin precedentes por parte de los gobiernos a todos los niveles, la sociedad civil y el sector privado, y millones de decisiones y acciones a nivel individual. Para su consecución, los Objetivos de Desarrollo Sostenible requerirán un marco de seguimiento y rendición de cuentas y un plan de ejecución. El plan de acción para los Objetivos de Desarrollo Sostenible deberá contener el firme compromiso de aprovechar las oportunidades de la revolución de los datos, con el fin de apoyar a los países más necesitados de recursos y para dar al mundo un impulso sin precedentes hacia un nuevo mundo de datos por el cambio.

Las músicas populares urbanas participan en la construcción, transmisión y deconstrucción de las imágenes de género. Es trascendental comprender su influencia entre los oyentes. Para ello, realizamos una investigación basada en encuestas a jóvenes universitarios que mostró la permanencia de prejuicios y una escasa capacidad crítica, lo que refuerza algunas de las hipótesis de la sociología de la música de T. W. Adorno y plantea cuestiones importantes para la musicología feminista. Es necesario tener conciencia de la existencia de estos prejuicios si pretendemos una educación emancipatoria.

Contemporary orthodontics has sought, beyond the esthetic, occlusal and functional goals, treatments even faster and with less visits to the orthodontist — especially in patients that require dental extractions in which the generated space becomes a nuisance. The segmented arch technic (SAT), by the use of a "T" loop spring, has provided such results within these requirements. Therefore, this study aimed to appraise and demonstrate the confection, activation and biomechanical control of "T" loop spring, in the group with high anchorage necessity (group A), for retraction of anterior teeth; as well as to present a case report, with high anterior retraction necessity, treated with "T" loop spring.

Objetive: Evaluate the deformations caused in the cutting edges in the K-file #25 (LK), subjected to pre-beinding of the apcial third using the following methods: finder-bending, cotton-pliers bendin and Flexobend, observed under scanning electron microscopy (SEM). Material and methods: Forty-eight LK#25 were divides into 4 groups (n=12); G1, control; G2, finger-bending; G3, cotton-plier bending, G4, Flexobend. The curvature was standardized in the apical segment of the file at 2 mm of D!. Was constructed a model of acrylic resin that correspond to a canal of 20º of curvature. The files were examined under SEM (260X). Data were analyzed using Fisher´s statistical test with a significance level of 5%. Results: The images showed no alterations in the LK, similar to G3, with no statistical difference. G3 and G4 were statistically different form the other groups (p<0.05). Conclusions: the finger-bending method to curve apical third of LK #25 did not alter the cutting edges, the cotton-pliers bending and Flexobend did alter the cutting edges of the files (AU)

This study aimed to analyze the literature on social support in the database ebsco-Academic Search between 2001 and 2011. It was based on a search for items that had the words "social support" and "scale" in the abstract. The sample consisted of 107 studies. It was verified in the results that there were fluctuations in the number of studies over the years. Aging & Mental Health and Quality of Life Research were the journals which published the most. On the country of residence of the first author, the countries that dominated were United States and England. 34 different instruments were used to assess social support. We also observed a lack of information concerning the psychometric qualities in the instruments descriptions.
