This research comprises some considerations about production, productivity and scientific collaboration related to Information Science in geopolitical regions of Brazil, aiming at identifying their macro-level flow and trends. Reports were generated through identification of Information Science postgraduate programs and professors and collaborators who work on them - those reports were synthesized according to programs and regions, from the year of 2007 to 2009. We can conclude that the Southeast and Northeast regions are responsible for the higher production, productivity and collaboration indicators; we can also infer that the expansion of the relationship among different regions may offer the researchers opportunities to establish new partnerships, and to develop researches on emerging subjects in this scientific area

En este trabajo nos proponemos hacer una aproximación a las prácticas de Responsabilidad Social Empresaria (el adelante, RSE) llevadas adelante en Argentina por las grandes empresas suscriptas al Pacto Global (ONU) para el período 2008-2009. Fundamentalmente, nos interesa dar cuenta de la naturaleza de la intervención de las empresas en lo social. Para esto en primer lugar revisaremos el concepto de RSE, incluyendo las diferentes visiones acerca del mismo, y pensaremos el rol del Pacto Global como marco de referencia institucional de estas prácticas. En una segunda instancia, haremos una aproximación a las modalidades que adopta la RSE en Argentina analizando, entre otras cosas, las áreas de intervención, los tipos de contribución y las alianzas con otros actores (tales como ONGs, fundaciones, universidades y sector público entre otros)

La pregunta que orienta la propuesta de investigación es ¿Qué lugar ocupa la participación de los docentes en el diseño las políticas de capacitación? ¿Cuáles son los aspectos que inciden en la elección de la oferta de capacitación? La intención es analizar los factores que inciden en la elección de la oferta de capacitación estatal y/o privada, que realizan los docentes del área Educación Física pertenecientes al sector estatal, que se desempeñan en escuelas medias del distrito de La Plata. Son considerados los aportes de los estudios sobre saber docente, el proceso de análisis de las políticas públicas, las regulaciones del trabajo docente y la institucionalización de ciertas modalidades de capacitación. Desde un enfoque cualitativo, la estrategia metodológica utilizará fuentes de datos orales y documentales, a través de entrevistas en profundidad y análisis de documentos que regulan la capacitación en la provincia

Lake ice change is one of the sensitive indicators of regional and global climate change. Different sources of data are used in monitoring lake ice phenology nowadays. Visible and Near Infrared bands of imagery (VNIR) are well suited for the observation of freshwater ice change, for example data from AVHRR and MODIS. Active and passive microwave data are also used for the observation of lake ice, e.g., from satellite altimetry and radiometry, backscattering coefficient from QuickSCAT, brightness temperature (Tb) from SSM/I, SMMR, and AMSR-E. Most of the studies are about lake ice cover phenology, while few studies focus on lake ice thickness. For example, Hall et al. using 5 GHz (6 cm) radiometer data showed a good relationship between Tb and ice thickness. Kang et al. found the seasonal evolution of Tb at 10.65 GHz and 18.7 GHz from AMSR-E to be strongly influenced by ice thickness. Many studies on lake ice phenology have been carried out since the 1970s in cold regions, especially in Canada, the USA, Europe, the Arctic, and Antarctica. However, on the Tibetan Plateau, very little research has focused on lake ice-cover change; only a small number of published papers on Qinghai Lake ice observations. The main goal of this study is to investigate the change in lake ice phenology at Nam Co on the Tibetan Plateau using MODIS and AMSR-E data (monitoring the date of freeze onset, the formation of stable ice cover, first appearance of water, and the complete disappearance of ice) during the period 2000-2009.

Shrubs and trees are expected to expand in the sub-Arctic due to global warming. Our study was conducted in Abisko, sub-arctic Sweden. We recorded the change in coverage of shrub and tree species over a 32- to 34-year period, in three 50 x 50 m plots; in the alpine-tree-line ecotone. The cover of shrubs and trees (<3.5 cm diameter at breast height) were estimated during 2009-2010 and compared with historical documentation from 1976 to 1977. Similarly, all tree stems (>=3.5 cm) were noted and positions determined. There has been a substantial increase of cover of shrubs and trees, particularly dwarf birch (Betula nana), and mountain birch (Betula pubescens ssp. czerepanovii), and an establishment of aspen (Populus tremula). The other species willows (Salix spp.), juniper (Juniperus communis), and rowan (Sorbus aucuparia) revealed inconsistent changes among the plots. Although this study was unable to identify the causes for the change in shrubs and small trees, they are consistent with anticipated changes due to climate change and reduced herbivory.

Global change in land water storage and its effect on sea level is estimated over a 7-year time span (August 2002 to July 2009) using space gravimetry data from GRACE. The 33 World largest river basins are considered. We focus on the year-to-year variability and construct a total land water storage time series that we further express in equivalent sea level time series. The short-term trend in total water storage adjusted over this 7-year time span is positive and amounts to 80.6 ± 15.7 km**3/yr (net water storage excess). Most of the positive contribution arises from the Amazon and Siberian basins (Lena and Yenisei), followed by the Zambezi, Orinoco and Ob basins. The largest negative contributions (water deficit) come from the Mississippi, Ganges, Brahmaputra, Aral, Euphrates, Indus and Parana. Expressed in terms of equivalent sea level, total water volume change over 2002-2009 leads to a small negative contribution to sea level of -0.22 ± 0.05 mm/yr. The time series for each basin clearly show that year-to-year variability dominates so that the value estimated in this study cannot be considered as representative of a long-term trend. We also compare the interannual variability of total land water storage (removing the mean trend over the studied time span) with interannual variability in sea level (corrected for thermal expansion). A correlation of ~0.6 is found. Phasing, in particular, is correct. Thus, at least part of the interannual variability of the global mean sea level can be attributed to land water storage fluctuations.
