Organizations and the united nations millennium development goals: evidence from some of the largest companies in brazil

The objective of this study is to verify whether some of the largest companies in Brazil adopt management practices aligned with the UN Millennium Development Goals (MDGs). Design/methodology/approach – Overview information obtained from the web sites of six Brazilian multinational companies listed in the Forbes Global 2000 ranking was analyzed. Findings – The major findings of this study indicate that the companies studied did not demonstrate clear knowledge of the MDGs, nor did they adopt practices aiming at meeting those goals. The evidences show that the companies adopt corporate social responsibility (CSR) practices, which are indirectly related to four MDGs. It was observed that the CSR practices tend to be developed based on a contingency perspective according to the characteristics and impacts of products offered by those companies. Therefore, there is a window of opportunity for those companies to begin developing programs in order to meet the MDGs aiming at new business opportunities, innovative CSR practices, and new ways to make CSR information evident and more organized.

Knowledge on dental trauma and orthodontic tooth movement held by a group of orthodontists

The objective of this work was to assess the knowledge about orthodontic tooth movement and dental trauma held by a group of orthodontists in specific areas of Brazil. For this purpose, 166 questionnaires with 15 objective questions about this subject were distributed. One hundred and five questionnaires were properly filled and collected after 30 days. It was concluded that, except for avulsion, the knowledge on dental injuries held by the professionals interviewed was considered unsatisfactory, and about 40% of them were not acquainted with the recommendations for the orthodontic movement of traumatized teeth.

New species of pyrrhulina (Ostariophysi: Characiformes: Lebiasinidae) from the brazilian shield, with comments on a putative monophyletic group of species in the genus

Pyrrhulina marilynae, new species, is described. The new species can be distinguished among congeners mainly by pre-senting a conspicuous, dark, zigzag shaped primary stripe, extending to distal end of median caudal-fin rays, reduction of the number of precaudal vertebrae, absence of postcleithrum 2, and nine principal rays on caudal-fin dorsal lobe. The pu-tative relationship of the new species with Pyrrhulina australis, P. vittata and P. zigzag, three small-sized species of the genus, is discussed. Copyright © 2013 Magnolia Press.

O padrão de compressão de video MPEG moving picture experts group

This work focuses on the study of video compression standard MPEG. To this end, a study was undertaken starting from the basics of digital video, addressing the components necessary for the understanding of the tools used by the video coding standard MPEG. The Motion Picture Experts Group (MPEG) was formed in the late '80s by a group of experts in order to create international standards for encoding and decoding audio and video. This paper will discuss the techniques present in the video compression standard MPEG, as well as its evolution. Will be described in the MPEG-1, MPEG-2, MPEG-4 and H.264 (MPEG-4 Part 10), however, the last two will be presented with more emphasis, because the standards are present in most modern video technologies, as in HDTV broadcasts
