  • The Christian Church and the New Religious Movements: Towards Theological Understanding John A
    THE CHRISTIAN CHURCH AND THE NEW RELIGIOUS MOVEMENTS: TOWARDS THEOLOGICAL UNDERSTANDING JOHN A. SALIBA, S.J. University of Detroit OR MORE than a decade Western society, in particular the United FStates of America,1 has seen the rise and proliferation of religious and spiritual groups which the public has undiscerningly and indiscriminately labeled "cults." Many of the adherents of these new groups have come from the background of the traditional Christian churches. Most of them, by abandoning the beliefs and practices of their forefathers, have passed a negative judgment on the Christian Church and its relevance to contemporary life. The so-called cults have often been in the public eye because of the legal actions and Congressional investigations instigated by anticult organizations. Anguished parents, whose children have be­ come cult members, have turned to self-styled déprogrammera who have at times operated outside both civil and moral law. Yet the mainline Christian response to the new religions can, with few exceptions, be categorized as one of neglect and apathy. Though the churches have made extensive efforts to come to grips with the cultural upheavals of the mid-1960's,2 their attempts to meet the challenge of the cults have, on the whole, been slow, sporadic, and superficial. Many Christians, theologians included, have failed to grasp the significance of the new religious movements, which are already leaving an impact on society at large and on Christianity itself. It is unfortunate that we still lack a systematic treatment of the theological implications of these movements. The only concerted Christian response has come from evangelical Christianity, which has directed a considerable amount of literature3 to 1 See The Spiritual Community Guide (San Rafael, Calif.: Spiritual Community, 1978) and Gordon Melton, The Encyclopedia of American Religions 2 (Wilmington, N.C.: McGrath, 1978).

  • List of Different Digital Practices 3
    Categories of Digital Poetics Practices (from the Electronic Literature Collection) http://collection.eliterature.org/1/ (Electronic Literature Collection, Vol 1) http://collection.eliterature.org/2/ (Electronic Literature Collection, Vol 2) Ambient: Work that plays by itself, meant to evoke or engage intermittent attention, as a painting or scrolling feed would; in John Cayley’s words, “a dynamic linguistic wall- hanging.” Such work does not require or particularly invite a focused reading session. Kinetic (Animated): Kinetic work is composed with moving images and/or text but is rarely an actual animated cartoon. Transclusion, Mash-Up, or Appropriation: When the supply text for a piece is not composed by the authors, but rather collected or mined from online or print sources, it is appropriated. The result of appropriation may be a “mashup,” a website or other piece of digital media that uses content from more than one source in a new configuration. Audio: Any work with an audio component, including speech, music, or sound effects. CAVE: An immersive, shared virtual reality environment created using goggles and several pairs of projectors, each pair pointing to the wall of a small room. Chatterbot/Conversational Character: A chatterbot is a computer program designed to simulate a conversation with one or more human users, usually in text. Chatterbots sometimes seem to offer intelligent responses by matching keywords in input, using statistical methods, or building models of conversation topic and emotional state. Early systems such as Eliza and Parry demonstrated that simple programs could be effective in many ways. Chatterbots may also be referred to as talk bots, chat bots, simply “bots,” or chatterboxes.

By Willy Fautré The Israeli Center for Victims of Cults About the so-called experts of the Israeli Center for Victims of Cults and Yad L'Achim Rami Feller ICVC Directors Some Other So-called Experts Some Dangerous Liaisons of the Israeli Center for Victims of Cults Conclusions Annexes Brussels, 1 September 2018 The Israeli Center for Victims of Cults Who is Who? Who is Behind it? The Israeli Center for Victims of Cults (ICVC) is well-known in Israel for its activities against a number of religious and spiritual movements that are depicted as harmful and dangerous. Over the years, the ICVC has managed to garner easy access to the media and Israeli government due to its moral panic narratives and campaign for an anti-cult law. It is therefore not surprising that the ICVC has also emerged in Europe, in particular, on the website of FECRIS (European Federation of Centers of Research and Information on Cults and Sects), as its Israel correspondent.1 For many years, FECRIS has been heavily criticized by international human rights organizations for fomenting social hostility and hate speech towards non-mainstream religions and worldviews, usually of foreign origin, and for stigmatizing members of these groups.2 Religious studies scholars and the scientific establishment in general have also denounced FECRIS for the lack of expertise of their so-called “cult experts”.

  • The Post Infocom Text Adventure Collection
    The Post Infocom Text Adventure Collection Many of us played and loved the text adventures produced by Infocom in the 1980’s. They were rich in story and puzzles, and contained some excellent writing. In the years since Infocom’s demise in 1989, there have been a lot of good games produced using the Z-Machine - the game format that Infocom was using. This gives us a chance to make these modern-day games run on the computers of the 80’s, like the Commodore 64. I decided to create a collection of Z-machine games for the C64, and this is it. All in all, it’s 31 games, released in 1993-2015. Each game has been put into its own directory, in which is also an empty disk for game saves and a file called AUTOSWAP.LST to make life easier for people using the SD2IEC diskdrive substitute. If you haven’t played text adventures before, or feel that you never got the hang of it, you should read the chapter How to play a text adventure. If you want more of a background on Infocom and the game format they used, you should read the chapter about The Zork Machine at the end of this document. There is also a chapter about the process of porting Z-machine games to the C64 and, finally, a chapter about writing your own games. I created this documentation as a PDF, so that you could easily print it out and keep it nearby if you’re enjoying the collection on a real C64.

  • Researching New Religious Movements
    Researching New Religious Movements ‘The most important “first” that this book achieves is its bold questioning of the whole intellectual apparatus of the sociology of religion as it has been applied to the understanding of the new religious movements. I am confident that Elisabeth Arweck’s study will quickly become required reading in the sociology of new religious movements.’ Professor David Martin, Emeritus Professor of Sociology, London School of Economics, University of London ‘Powerful and original . it succeeds triumphantly in being at the same time an important, high-quality academic study and a book for our times.’ Professor David Marsland, Professorial Research Fellow in Sociology, University of Buckingham New religious movements such as Scientology, Jehovah’s Witnesses and the Unification Church (Moonies) are now well established in mainstream cul- tural consciousness. However, responses to these ‘cult’ groups still tend to be overwhelmingly negative, characterized by the furious reactions that they evoke from majority interests. Modern societies need to learn how to respond to such movements and how to interpret their benefits and dangers. Researching New Religious Movements provides a fresh look at the history and development of ‘anti-cult’ groups and the response of main- stream churches to these new movements. In this unique reception study, Elisabeth Arweck traces the path of scholarship of new religious move- ments, exploring the development of research in this growing field. She con- siders academic and media interventions on both sides, with special emphasis on the problems of objectivity inherent in terminologies of ‘sects’, ‘cults’, and ‘brainwashing’. Ideal for students and researchers, this much- needed book takes the debate over new religious movements to a more sophisticated level.

  • Introduction to the ICSA 2007 Annual Conference
    Introduction to the ICSA 2007 Annual Conference Michael Langone, Ph.D., Executive Director, ICSA Michael Kropveld, Executive Director, Info-Cult About the International Cultic Studies Association and Info-Cult Founded in 1979, the International Cultic Studies Association (ICSA) is a network of people concerned about cultic, manipulative, and abusive groups. As the leading professional organization in the field, ICSA strives to increase understanding and awareness of such groups and to help people that they harm. ICSA seeks to apply academic and professional research and analyses to the practical problems of families and individuals harmed by cultic experiences and to the professionals who seek to help them and/or forewarn those who might become involved in harmful group situations. ICSA is funded by individuals and foundations. Founded in 1980, Info-Cult is a non-profit charitable organization whose objectives are to: • Promote the study of cultic phenomena; • Inform, raise awareness and educate the public about these phenomena; • Help people with problems related to these phenomena. Info-Cult is funded in part by the Quebec Provincial Ministry of Health and Social Services and operates in both English and French. It houses one of the most unique collections of materials on "cults", "new religious movements" and related groups and subjects. Definitional Issues A central component of ICSA’s mission is to study psychological manipulation and abuse, especially as it manifests in cultic and other groups. Different people, attach different and usually imprecise meanings to the term “cult.” Those who have sought information from ICSA and Info-Cult have – properly or improperly –used “cult” to refer to a wide variety of phenomena.
