"Hands on Media History explores the whole range of hands on media history techniques for the first time, offering both practical guides and general perspectives. It covers both analogue and digital ...media; film, television, video, gaming, photography and recorded sound. Understanding media means understanding the technologies involved. The hands on history approach can open our minds to new perceptions of how media technologies work and how we work with them. Essays in this collection explore the difficult questions of reconstruction and historical memory, and the issues of equipment degradation and loss. Hands on Media History is concerned with both the professional and the amateur, the producers and the users, providing a new perspective on one of the modern era’s most urgent questions: what is the relationship between people and the technologies they use every day? Engaging and enlightening, this collection is a key reference for students and scholars of media studies, digital humanities, and for those interested in models of museum and research practice."

From the queasy zooms in Alfred Hitchcock'sVertigoto the avant-garde mystery of Michael Snow'sWavelength, from the excitement of televised baseball to the drama of the political convention, the zoom ...shot is instantly recognizable and highly controversial. InThe Zoom, Nick Hall traces the century-spanning history of the zoom lens in American film and television. From late 1920s silent features to the psychedelic experiments of the 1960s and beyond, the book describes how inventors battled to provide film and television studios with practical zoom lenses, and how cinematographers clashed over the right ways to use the new zooms. Hall demonstrates how the zoom brought life and energy to cinema decades before the zoom boom of the 1970s and reveals how the zoom continues to play a vital and often overlooked role in the production of contemporary film and television.
To examine the role of intracellular labile iron pool (LIP), ferritin (Ft), and antioxidant defence in cellular resistance to oxidative stress on chronic adaptation, a new H2O2-resistant Jurkat T ...cell line “HJ16” was developed by gradual adaptation of parental “J16” cells to high concentrations of H2O2. Compared to J16 cells, HJ16 cells exhibited much higher resistance to H2O2-induced oxidative damage and necrotic cell death (up to 3mM) and had enhanced antioxidant defence in the form of significantly higher intracellular glutathione and mitochondrial ferritin (FtMt) levels as well as higher glutathione-peroxidase (GPx) activity. In contrast, the level of the Ft H-subunit (FtH) in the H2O2-adapted cell line was found to be 7-fold lower than in the parental J16 cell line. While H2O2 concentrations higher than 0.1mM fully depleted the glutathione content of J16 cells, in HJ16 cells the same treatments decreased the cellular glutathione content to only half of the original value. In HJ16 cells, H2O2 concentrations higher than 0.1mM increased the level of FtMt up to 4-fold of their control values but had no effect on the FtMt levels in J16 cells. Furthermore, while the basal cytosolic level of LIP was similar in both cell lines, H2O2 treatment substantially increased the cytosolic LIP levels in J16 but not in HJ16 cells. H2O2 treatment also substantially decreased the FtH levels in J16 cells (up to 70% of the control value). In contrast in HJ16 cells, FtH levels were not affected by H2O2 treatment. These results indicate that chronic adaptation of J16 cells to high concentrations of H2O2 has provoked a series of novel and specific cellular adaptive responses that contribute to higher resistance of HJ16 cells to oxidative damage and cell death. These include increased cellular antioxidant defence in the form of higher glutathione and FtMt levels, higher GPx activity, and lower FtH levels. Further adaptive responses include the significantly reduced cellular response to oxidant-mediated glutathione depletion, FtH modulation, and labile iron release and a significant increase in FtMt levels following H2O2 treatment.
•We developed a new H2O2-resistant Jurkat T cell line by chronic adaptation to H2O2.•Cells displayed higher glutathione and mitochondrial ferritin levels but lower ferritin.•Cells possessed higher glutathione peroxidase but not higher catalase activity.•Cells had reduced response to H2O2-mediated glutathione depletion and iron release.•Cells acquired higher mitochondrial ferritin levels following H2O2 treatment.
Abstract Chondrosarcoma of the skull base is a rare tumour with a good prognosis following surgical resection. We describe a patient with low-grade chondrosarcoma of the skull base with intradural ...extramedullary spinal metastases. A 31-year-old female with grade 1 chondrosarcoma involving the cavernous sinus, sphenoid wing and clivus presented at age 19. The tumour was subtotally excised at initial surgery and over the following 4 years, 3 subsequent resections were undertaken for tumour progression followed by proton beam radiotherapy to the residual tumour. The patient re-presented with cervical radiculopathy 7 years later. MRI showed multiple, intradural extramedullary spinal drop metastases. Following surgical excision of the symptomatic lesion, histological diagnosis was confirmed as a mixed hyaline/myxoid grade 1 chondrosarcoma. Patients with skull base chondrosarcoma with intradural extension should have whole spine imaging as part of long-term monitoring to exclude drop metastases, particularly after intradural surgery.

This article is about The Privileged, a documentary series filmed by Westward Television in 1967 and broadcast in 1968 and 1969. The article offers the series as a case study of regional documentary ...production in a geographically peripheral ITV franchise area. It examines how documentaries were made by Westward despite the absence of a formalised documentary unit. This article shows how producers, editors and camera operators used their skills and experience to create an ambitious and innovative documentary television series within the more constrained budgets of regional independent television. Drawing on original production papers and preserved episodes of the series, this case study reveals how The Privileged took advantage of new production technologies and novel ways of filming and editing. It also considers the archival afterlife of the series, which has been largely been forgotten since its original transmission. The article concludes by drawing attention to some of the problems with the series' partial re-presentation on the BFI Player website, and highlights the potential social and cultural benefits which could be obtained by enhancing access to archival documentaries such as The Privileged.
In 1973, in response to pressure from trade unions and women's groups, and a damning report that exposed the discriminatory policies and attitudes underpinning women's employment, the British ...Broadcasting Corporation (BBC) committed to the recruitment of women into previously male-only technical occupations. This article examines draws upon public and private archives, and oral history interviews with former BBC women film and television camera operators, to assess the extent to which the Corporation's commitment to equality brought about sustained change to women's opportunities in technical areas of television. Although stereotypical assumptions about women's technical ability proved unfounded, women's employment in camera roles continued to be restricted through recruitment policies and procedures that favoured male applicants. Women's entry into technical areas also challenged existing gendered power relations and workplace culture within television studios. The BBC's inadequate commitment to meaningful change to discriminatory work practices further entrenched the equation of technical skill with masculine labour.
A low-key announcement in the September 1962 edition ofAmerican Cinematographer, which noted that the camera manufacturer Arriflex was selling “a new zoom lens for Arriflex 16—the Angénieux Model ...120—which zooms from 12mm to 120mm focal length,” gave little clue of the transformation that was soon to take place in the zoom lens market.¹ Though the zoom was an increasingly well-established technique by the beginning of the 1960s, especially in television, until December 1962, the promotion and discussion of zoom technology inAmerican Cinematographerhad been relatively inconspicuous. Throughout 1963, by contrast, the magazine was full of articles
Modern television coverage of sports fixtures, political rallies, and similar live events offers viewers a remarkable level of access. At the sports ground, powerful zoom lenses positioned high in ...the stadium can swoop down in seconds to pick out individual players in extreme close-up. Digital effects systems superimpose graphics on live footage in real time, highlighting the position of a hockey puck or marking out the line of scrimmage in a football game. In the highest-profile sports coverage, camera operators wearing Steadicam rigs run the touchline while cameras suspended from cables provide a top-down view reminiscent of video gaming. For
