A Contratiempo | Sonidos y sentidos: Entrevista con Steven Feld Sonidos y sentidos: Entrevista con Steven FeldRita de Cácia Oenning da Silva 1Universidad Federal de Santa Catarina Aunque para cualquier etnomusicólogo Steven Feld no requiere presentación, la presente entrevista titulada Sonidos y Sentidos, que apareció recientemente en la Revista de antropología de la Universidad de Sao Paulo 2, abre con una introducción de su realizadora, Rita de Cácia, en la que da buena cuenta de lo interesante y valioso del entrevistado y de la entrevista misma. Enfatiza también Feld en la importancia de publicar en formatos alternativos al texto: Cds, Dvds, para ver y escuchar, y se esfuerza por argumentar la importancia de realizar antropología no solo del sonido sino a través del sonido, pero a la vez reconoce las dificultades del aval académico con que aún cuentan estos formatos y medios de divulgación del conocimiento. De paso, por si fuera poco, nos ilustra sobre su vida, su postura ante la investigación, y su proyecto editorial de libros, discos y videos.

CNRI Handles - Handle.Net Registry Deep Web Search Engines | Deep Web Search - A How-To Site Where to start a deep web search is easy. You hit and when you brick wall it, you go to which is the academic database of Google. After you brick wall there, your true deep web search begins. You need to know something about your topic in order to choose the next tool. To all the 35F and 35G’s out there at Fort Huachuca and elsewhere, you will find some useful links here to hone in on your AO. If you find a bad link, Comment the link below. Last updated July 12, 2016 – updated reverse image lookup. Multi Search engines – (broken as of Sept 2016, hopefully not dead) This is my favorite search engine. Surfwax – They have a 2011 interface for rss and a 2009 interface I think is better. – You can filter the search by domain extension, or by topic which is quite neat. Cluster Analysis Engine TouchGraph – A brilliant clustering tool that shows you relationships in your search results using a damn spiffy visualization. General Videos

PURL help What is a PURL? A PURL is a persistent URL, it provides a permanent address to access a resource on the web. When a user retrieves a PURL they will be redirected to the current location of the resource. When an author needs to move a page they can update the PURL to point to the new location. PURLs with a common prefix are grouped together into domains. PURL types Each PURL has a target and status code or type. A partial PURL is a special type which will match the beginning of a URL. The HTTP status code definitions provides more detail about the different status codes and thier meanings. Claiming a PURL domain The PURL service is now administered by the Internet Archive. Administering PURLs The PURL system is a service of the Internet Archive. Search for a PURL PURLs are grouped into domains, domains can be searched from the home page. The domain search shows a list of domains that match the search criteria. Viewing the contents of a PURL domain Version This is version 1.2.2.

White Paper: The Deep Web: Surfacing Hidden Value This White Paper is a version of the one on the BrightPlanet site. Although it is designed as a marketing tool for a program "for existing Web portals that need to provide targeted, comprehensive information to their site visitors," its insight into the structure of the Web makes it worthwhile reading for all those involved in e-publishing. —J.A.T. Searching on the Internet today can be compared to dragging a net across the surface of the ocean. Traditional search engines create their indices by spidering or crawling surface Web pages. The deep Web is qualitatively different from the surface Web. If the most coveted commodity of the Information Age is indeed information, then the value of deep Web content is immeasurable. The Deep Web Internet content is considerably more diverse and the volume certainly much larger than commonly understood. First, though sometimes used synonymously, the World Wide Web (HTTP protocol) is but a subset of Internet content. How Search Engines Work Figure 1.

Persistent uniform resource locator - Wikipedia A persistent uniform resource locator (PURL) is a uniform resource locator (URL) (i.e., location-based uniform resource identifier or URI) that is used to redirect to the location of the requested web resource. PURLs redirect HTTP clients using HTTP status codes. PURLs are used to curate the URL resolution process, thus solving the problem of transitory URIs in location-based URI schemes like HTTP. Technically the string resolution on PURL is like SEF URL resolution. History[edit] The PURL concept was developed at OCLC (the Online Computer Library Center) in 1995 and implemented using a forked pre-1.0 release of Apache HTTP Server.[1] The software was modernized and extended in 2007 by Zepheira under contract to OCLC and the official website moved to (the 'Z' came from the Zepheira name and was used to differentiate the PURL open-source software site from the PURL resolver operated by OCLC). PURL version numbers may be considered confusing. Principles of operation[edit]

The Ultimate Guide to the Invisible Web Search engines are, in a sense, the heartbeat of the internet; “Googling” has become a part of everyday speech and is even recognized by Merriam-Webster as a grammatically correct verb. It’s a common misconception, however, that Googling a search term will reveal every site out there that addresses your search. Typical search engines like Google, Yahoo, or Bing actually access only a tiny fraction — estimated at 0.03% — of the internet. The sites that traditional searches yield are part of what’s known as the Surface Web, which is comprised of indexed pages that a search engine’s web crawlers are programmed to retrieve. "As much as 90 percent of the internet is only accessible through deb web websites." So where’s the rest? So what is the Deep Web, exactly? Search Engines and the Surface Web Understanding how surface pages are indexed by search engines can help you understand what the Deep Web is all about. How is the Deep Web Invisible to Search Engines? Reasons a Page is Invisible Art

Handle System - Wikipedia As with handles used elsewhere in computing, Handle System handles are opaque, and encode no information about the underlying resource, being bound only to metadata regarding the resource. Consequently, the handles are not rendered invalid by changes to the metadata. The system was developed by Bob Kahn at the Corporation for National Research Initiatives (CNRI). The original work was funded by the Defense Advanced Research Projects Agency (DARPA) between 1992 and 1996, as part a wider framework for distributed digital object services,[2] and was thus contemporaneous with the early deployment of the World Wide Web, with similar goals. The Handle System was first implemented in autumn 1994, and was administered and operated by CNRI until December 2015, when a new "multi-primary administrator" (MPA) mode of operation was introduced. Thousands of handle services are currently running. Specifications[edit] Some Handle System namespaces define special presentation rules. Implementation[edit]

News aggregator - Wikipedia Client software that aggregates syndicated web content The User interface of the feed reader Tiny Tiny RSS In computing, a news aggregator, also termed a feed aggregator, feed reader, news reader, RSS reader, or simply an aggregator is client software or a web application that aggregates syndicated web content such as online newspapers, blogs, podcasts, and video blogs (vlogs) in one location for easy viewing. The updates distributed may include journal tables of contents, podcasts, videos, and news items.[1] Function[edit] History[edit] RSS began in 1999 "when it was first introduced by Internet browser pioneer Netscape".[2] In the beginning, RSS was not a user-friendly gadget and it took some years to spread. "...RDF-based data model that people inside Netscape felt was too complicated for end users Types[edit] Web aggregators gather material from a variety of sources for display in one location.
