  • Immersion Into Noise
    Immersion Into Noise Critical Climate Change Series Editors: Tom Cohen and Claire Colebrook The era of climate change involves the mutation of systems beyond 20th century anthropomorphic models and has stood, until recent- ly, outside representation or address. Understood in a broad and critical sense, climate change concerns material agencies that im- pact on biomass and energy, erased borders and microbial inven- tion, geological and nanographic time, and extinction events. The possibility of extinction has always been a latent figure in textual production and archives; but the current sense of depletion, decay, mutation and exhaustion calls for new modes of address, new styles of publishing and authoring, and new formats and speeds of distri- bution. As the pressures and re-alignments of this re-arrangement occur, so must the critical languages and conceptual templates, po- litical premises and definitions of ‘life.’ There is a particular need to publish in timely fashion experimental monographs that redefine the boundaries of disciplinary fields, rhetorical invasions, the in- terface of conceptual and scientific languages, and geomorphic and geopolitical interventions. Critical Climate Change is oriented, in this general manner, toward the epistemo-political mutations that correspond to the temporalities of terrestrial mutation.

  • Scripting and Consuming Black Bodies in Hip Hop Music and Pimp Movies
    SCRIPTING AND CONSUMING BLACK BODIES IN HIP HOP MUSIC AND PIMP MOVIES Ronald L Jackson II and Sakile K. Camara ... Much of the assault on the soulfulness of African American people has come from a White patriarchal, capitalist-dominated music industry, which essentially uses, with their consent and collusion, Black bodies and voices to be messengers of doom and death. Gangsta rap lets us know Black life is worth nothing, that love does not exist among us, that no education for critical consciousness can save us if we are marked for death, that women's bodies are objects, to be used and discard­ ed. The tragedy is not that this music exists, that it makes a lot of money, but that there is no countercultural message that is equally powerful, that can capture the hearts and imaginations of young Black folks who want to live, and live soulfully) Feminist film critics maintain that the dominant look in cinema is, historically, a gendered gaze. More precisely, this viewpoint argues that the dominant visual and narrative conventions of filmmaking generally fix "women as image" and "men as bearer of the image." I would like to suggest that Hollywood cinema also frames a highly particularized racial gaze-that is, a representational system that posi­ tions Blacks as image and Whites as bearer of the image.2 Black bodies have become commodities in the mass media marketplace, particu­ larly within Hip Hop music and Black film. Within the epigraph above, both hooks and Watkins explain the debilitating effects that accompany pathologized fixations on race and gender in Black popular culture.

  • Composite Material Advances in the Golf Industry
    COMPOSITE MATERIAL ADVANCES IN THE GOLF INDUSTRY Jerome S. Berg Manager of Technical Service, True Temper Sports Society of Manufacturing Engineers-Board Advisor Representing the Recreation Industry SUMMARY: The popularity of carbon fiber composites as a primary structure for components in sporting goods appeared to gain momentum in the late 1980s and early 1990s. Particularly in the golf industry, these materials offered lighter weight, a variety of design options not possible with steel, and a high tech image to a rather affluent market. The sporting goods consumer desires equipment which represents the latest technology and is more expensive than his competitor’s. Sporting goods companies are searching for the next advanced material that will allow them to gain another niche in the marketplace which will command a higher price and margin. Successfully implementing these new technologies with the associated research and development requires partnerships among the sporting goods industries, the material vendors, and the academic community. Several product development efforts including metal matrix materials, robust resin systems, and high modulus carbon fibers are discussed. KEYWORDS: sporting goods, golf, metal matrix, composites INTRODUCTION Background and Historical Perspective Advanced materials and new processing technology has created the phenomenon of high-end sporting and recreational equipment for which sports enthusiasts are willing to pay a premium. It is not uncommon to find someone who is willing to pay $2500 for a cutting-edge bicycle made from advanced materials or $500 for a golf club driver. In fact, many of the dilemmas in introducing expensive composite materials faced by the aerospace markets are actually opportunities in the sports market, where a higher material price and material prestige is often a marketing advantage.

    Best Practice Update: GOVERNOR MAINTENANCE ALL Power Labs Technical Bulletin: #TB­795­00006 Release Date: July 2016 SUBJECT: Governor Throttle Cleaning & Maintenance Pro ​ cedure. Availability of Governor Manifold Upgrade Kit (UGK) Part # 877­00017 A Models: PP20 ​ Symptom: Governor’s throttle plate gets stuck shut, so engine won’t start. Also, poor performance and/or low or ​ varying power, and “hunting” (i.e. rising and falling of engine RPM/frequency) from “crunchy,” unsmooth throttle motion. Cause: Tar and soot building up in governor throttle butterfly shaft and bearings preventing smooth and free ​ movement. Governor throttle be eaned y un & checked eaned e If the Actions:​ ​must cl after ever r or cl ​ befor starting. following procedure is strictly adhered to on new governors, bearings should remain free. Procedure: Clean and lubricate the throttle shaft, throttle butterfly plate and throat thoroughly immediately ​ after every shutdown. NOTE: Cleaning is much easier when the dirt is fresh and parts are warm. If the normal tar deposits are not cleaned following a run, they can thicken as they cool and may glue the throttle closed which can keep engine from starting. If you wait to clean, it will take more solvent and effort to get it clean. You will need rubber gloves, a squirt bottle of solvent, rags or paper towels, a long rod or screwdriver, automotive grease (white lithium, axle etc.) and 2.5 mm hex key. NOTE: If you do not already have a quick- release sani clamps, you should install the Governor Upgrade Kit (UGK APL # 877-00017 A) to make governor removal easier.
