  • Vertov: Between the Organism and the Machine

    Vertov: Between the Organism and the Machine

    Vertov: Between the Organism and the Machine MALCOLM TURVEY In every living being, we find that those things which we call parts are inseparable from the Whole to such an extent, that they can only be conceived in and with the latter; and the parts can neither be the measure of the Whole, nor the Whole be the measure of the parts. — Goethe I The standard reading of the work of Dziga Vertov argues that, due to his affiliation with the Constructivist group of avant-garde artists that emerged in the Soviet Union after the Bolshevik Revolution of 1917, Vertov employed the machine as the model for both his films and the new Soviet society depicted in them. In The Material Ghost, Gilberto Perez writes: [Vertov’s] Man with a Movie Camera [1929] pictures the city as a vast machine seen by the omnipresent seeing machine that is the camera. The structure of Vertov’s films, their aggregate space pieced together in the cutting room out of all the manifold things the mechanical eye can see, suggests the constructions of the engineer so prized in [the] new Soviet society.1 The centrality of the machine to Constructivist theory and practice, as well as to Vertov’s work, is beyond dispute. However, it has obscured the influence of other models on Vertov as he came to make Man with a Movie Camera in the late 1920s, including one that is often thought of as antithetical to the machine, namely, the organism. Most obviously, Man with a Movie Camera is structured according to the daily cycle of a complex living organism such as an animal or human being—sleep, 1.
  • A Brief History of Radio Broadcasting in Africa

    A Brief History of Radio Broadcasting in Africa

    A Brief History of Radio Broadcasting in Africa Radio is by far the dominant and most important mass medium in Africa. Its flexibility, low cost, and oral character meet Africa's situation very well. Yet radio is less developed in Africa than it is anywhere else. There are relatively few radio stations in each of Africa's 53 nations and fewer radio sets per head of population than anywhere else in the world. Radio remains the top medium in terms of the number of people that it reaches. Even though television has shown considerable growth (especially in the 1990s) and despite a widespread liberalization of the press over the same period, radio still outstrips both television and the press in reaching most people on the continent. The main exceptions to this ate in the far south, in South Africa, where television and the press are both very strong, and in the Arab north, where television is now the dominant medium. South of the Sahara and north of the Limpopo River, radio remains dominant at the start of the 21St century. The internet is developing fast, mainly in urban areas, but its growth is slowed considerably by the very low level of development of telephone systems. There is much variation between African countries in access to and use of radio. The weekly reach of radio ranges from about 50 percent of adults in the poorer countries to virtually everyone in the more developed ones. But even in some poor countries the reach of radio can be very high. In Tanzania, for example, nearly nine out of ten adults listen to radio in an average week.

December 2017 Copyright © 2017 Stellenbosch University All rights reserved Stellenbosch University https://scholar.sun.ac.za ETHICAL CONSIDERATIONS Historical research frequently requires investigations that have ethical dimensions. Although not to the same extent as in medical experimentation, for example, the social sciences do entail addressing ethical considerations. This research is conducted at the University of Stellenbosch and, as such, must be managed according to the institution’s Framework Policy for the Assurance and Promotion of Ethically Accountable Research at Stellenbosch University. The policy stipulates that all accumulated data must be used for academic purposes exclusively. This study relies on social sources and ensures that the university’s policy on the values and principles of non-maleficence, scientific validity and integrity is followed. All participating oral sources were informed on the objectives of the study, the nature of the interviews (such as the use of a tape recorder) and the relevance of their involvement.

    Moving Pictures: the History of Early Cinema by Brian Manley

    Discovery Guides Moving Pictures: The History of Early Cinema By Brian Manley Introduction The history of film cannot be credited to one individual as an oversimplification of any his- tory often tries to do. Each inventor added to the progress of other inventors, culminating in progress for the entire art and industry. Often masked in mystery and fable, the beginnings of film and the silent era of motion pictures are usually marked by a stigma of crudeness and naiveté, both on the audience's and filmmakers' parts. However, with the landmark depiction of a train hurtling toward and past the camera, the Lumière Brothers’ 1895 picture “La Sortie de l’Usine Lumière à Lyon” (“Workers Leaving the Lumière Factory”), was only one of a series of simultaneous artistic and technological breakthroughs that began to culminate at the end of the nineteenth century. These triumphs that began with the creation of a machine that captured moving images led to one of the most celebrated and distinctive art forms at the start of the 20th century. Audiences had already reveled in Magic Lantern, 1818, Musée des Arts et Métiers motion pictures through clever uses of slides http://en.wikipedia.org/wiki/File:Magic-lantern.jpg and mechanisms creating "moving photographs" with such 16th-century inventions as magic lanterns. These basic concepts, combined with trial and error and the desire of audiences across the world to see entertainment projected onto a large screen in front of them, birthed the movies. From the “actualities” of penny arcades, the idea of telling a story in order to draw larger crowds through the use of differing scenes began to formulate in the minds of early pioneers such as Georges Melies and Edwin S.

    Social Media for Libraries

    Social Media for Libraries Karen du Toit Archivist, Librarian, Blogger Social Media Devotee SABC Radio Archives, South Africa Vizify Bio [email protected] @karentoittoit Bekti Mulatiningsih Independent researcher Indonesia [email protected] @bmulatiningsih 1 Abstract The social media statistics of South Africa reveal an exponential increase in the use of social media. Libraries, as part of a community, cannot ignore this! Social media provide libraries instant and direct connection with their members regardless their geographical location. This paper explores social media use in libraries. The establishment of social media for the SABC Media Libraries is discussed to demonstrate a practical implementation of social media in libraries and archives. Tips and resources, with specific mention to Twitter and Facebook, as well as social media etiquette and social media policy guidelines are supplied. The literature of published articles and Infographic show the changing role of librarians in the social media era and the need for librarians to keep learning and update their skills to accommodate users’ needs. The focus should now be on how well we do social media for the library, not on whether we should do it or not! Keywords: Social Media, Libraries, Web 2.0, Librarians, Archives, SABC, South Africa 2 Introduction The question is not anymore about whether we should do social media, but how well we do social media! We don’t have a choice anymore! (Qualman, 2013) Many organizations and companies use social media and take advantage of it. The reason for using it is that many people use and are active in social media.
