Fuentes de información en internet en el área de economía y empresa

Hoy en día la información sufre una evolución y transformación constantes, y para cualquier análisis o estudio hay que tener muy en cuenta las fuentes de información existentes en internet. El objetivo de este artículo es hacer un recorrido por la red centrando el interés en la selección de fuentes de información económica y empresarial. A la hora de seleccionar las fuentes electrónicas disponibles hay que tener en cuenta la diversa tipología documental existente: publicaciones periódicas, monografías, workingpapers, tesis, informes, actas de congresos, normas, patentes, etc.

The Politics of Internet Regulation in Brazil : dynamics, factors, and actors in broadband policy

In May 2010, Brazil joined the roll of nations with a National Broadband Plan. The Decree nº 7,175/2010 had implemented a program that aimed to offer 30 million permanent broadband accesses until 2014 and established its main goals, such as accelerating economic and social development, promoting digital inclusion, reducing social and regional inequalities, promoting a generation of employment and income, and expanding electronic government services. However, the broadband access in Brazil is limited, expensive, and centralized in the main urban centres. Despite the fast growth in the past years due to mobile internet access, the market is still concentrated in the local incumbent operators that currently provide mobile services, landline services and Paid-TV services, resulting in a high level of market verticalization. The following dissertation investigates the constraint of broadband access development, the dynamics, the actors, and the factors that have delayed the roll-out of broadband services in Brazil. The study also promotes reflections about the challenge posed by the media, by costumers associations and by public opinion as critical observers of the policy making process. This research examines on the political influence towards regulation to determine the way policy will benefit interest groups. Many interviews have been conducted in order to understand the forces which have been acting in the telecommunications in Brazil after privatization, in 1998. This study aims to provide a better understanding of telecommunications regulatory process in Brazil, in order to help the country finding an adequate policy which can lead to the implementation of a broadband roll-out. The universal broadband access is the only way to benefit the whole society in Brazil with a satisfactory level of education and create more jobs and economic development regarding the plenty use of Information and Communications Technology (ICT).

Resilient internet connectivity at Myerscough College

Myerscough College, a land-based further and higher education college in the north west, is one of the approximately 160 further education colleges in England to take additional connections to Jisc’s Janet network. Ian Brown, director of IT and MIS at the college, talks to us about why they’ve taken an extra four connections.

Hydrocarbon sensors for oil spill prevention and response, Seward, Alaska, April 8th-10th, 2008: workshop proceedings

During April 8th-10th, 2008, the Aliance for Coastal Technology (ACT) partner institutions, University of Alaska Fairbanks (UAF), Alaska SeaLife Center (ASLC), and the Oil Spill Recovery Institute (OSRI) hosted a workshop entitled: "Hydrocarbon sensors for oil spill prevention and response" in Seward, Alaska. The main focus was to bring together 29 workshop participants-representing workshop managers, scientists, and technology developers - together to discuss current and future hydrocarbon in-situ, laboratory, and remote sensors as they apply to oil spill prevention and response. [PDF contains 28 pages] Hydrocarbons and their derivatives still remain one of the most important energy sources in the world. To effectively manage these energy sources, proper protocol must be implemented to ensure prevention and responses to oil spills, as there are significant economic and environmental costs when oil spills occur. Hydrocarbon sensors provide the means to detect and monitor oil spills before, during, and after they occur. Capitalizing on the properties of oil, developers have designed in-situ, laboratory, and remote sensors that absorb or reflect the electromagnetic energy at different spectral bands. Workshop participants identified current hydrocarbon sensors (in-situ, laboratory, and remote sensors) and their overall performance. To achieve the most comprehensive understanding of oil spills, multiple sensors will be needed to gather oil spill extent, location, movement, thickness, condition, and classification. No single hydrocarbon sensor has the capability to collect all this information. Participants, therefore, suggested the development of means to combine sensor equipment to effectively and rapidly establish a spill response. As the exploration of oil continues at polar latitudes, sensor equipment must be developed to withstand harsh arctic climates, be able to detect oil under ice, and reduce the need for ground teams because ice extent is far too large of an area to cover. Participants also recognized the need for ground teams because ice extent is far too large of an area to cover. Participants also recognized the need for the U.S. to adopt a multi-agency cooperation for oil spill response, as the majority of issues surounding oil spill response focuses not on the hydrocarbon sensors but on an effective contingency plan adopted by all agencies. It is recommended that the U.S. could model contingency planning based on other nations such as Germany and Norway. Workshop participants were asked to make recommendations at the conclusion of the workshop and are summarized below without prioritization: *Outreach materials must be delivered to funding sources and Congressional delegates regarding the importance of oil spill prevention and response and the development of proper sensors to achieve effective response. *Develop protocols for training resource managers as new sensors become available. *Develop or adopt standard instrument specifications and testing protocols to assist manufacturers in further developing new sensor technology. *As oil exploration continues at polar latitudes, more research and development should be allocated to develop a suite of instruments that are applicable to oil detection under ice.

Ortsbezogene Informationen in Internet-Datenbanken - das Beispiel "Baltic SeaWeb"

Whoever in future will need information about a location or an area, either literature, measurement data, photos or administrative information, might only click on that spot on a screen map in the internet. A search programme started thereby will offer all available information in databanks. A step forward to such a solution, to the retrieval of location related literature and measurement data from different kinds of databanks, is presented by the project “Baltic Sea Web” (http://www.baltic.vtt.fi/ demonstrator/index.html). The basic idea was to make the available information about a certain location accessible via a link of their geographical coordinates, longitude and latitude, to a map in a web browser
