Journal articles on the topic 'Walter Hilton'

This article explores the role of weeping in medieval practices of piety by performing a close reading of three medieval texts: Walter Hilton's The Ladder of Perfection, Catherine of Siena's Dialogue, and Margery Kempe's Book of Margery Kempe. Hilton emphasized the role of weeping in the journey to a contemplative life while Catherine focused on the typology of tears; both affirmed genuine tears as a method to communicate with the divine. Margery Kempe, known for her strong emotions, often aligned with Hilton's and Catherine's views but sometimes differed, especially with her attitudes about crying in public. Even as weeping and the church became more ritualized and formalized over time, the practice remained active in the religious imaginations of people. The paper concludes by suggesting that weeping as part of pious practices continued, though changed, through the writings of more contemporary Anglicans like Jeremy Taylor and Charles Wesley, as well as in the Pentecostal tradition.

Abstract This article explores the relationships between spirituality, spiritual theology, and practical theology. It proposes a synthesis of these disciplines – practical spiritual theology – as a method and methodology for retrieving the wisdom of historical Christian mystics for the purposes of sustaining and inspiring the spiritual life of contemporary Christians. The 14th century English mystic, Walter Hilton, is used to illustrate this synthesis in practice.

A year-long survey of grassland Asilidae was undertaken at Jacana Eco Estate, Hilton, KwaZulu-Natal, South Africa. The following 18 species of Asilidae, in alphabetical order, were encountered: Caenoura annulitarsis (Loew, 1858), Damalis monochaetes Londt, 1989, Dasophrys androclea (Walker, 1849), Dasophrys fortis Londt, 1981, Dasophrys tarsalis (Ricardo, 1920), Dasophrys umbripennis Londt, 1981, Dysclytus firmatus (Walker, 1857), Euscelidia vallis Dikow, 2003, Ischiolobos mesotopos Londt, 2005, Leptogaster sp., Melouromyia natalensis (Ricardo, 1919), Microstylum sp., Neolophonotus hirsutus (Ricardo, 1920), Neolophonotus variabilis Londt, 1986, Neolophonotus wroughtoni (Ricardo, 1920), Pegesimallus bicolor (Loew, 1858), Pegesimallus pedunculatus (Loew, 1858), Rhipidocephala obscurata Oldroyd, 1966. Their flight periods were recorded and tabulated. The variety and numbers encountered suggest that the grassland invertebrate community is healthy and that the grassland is worthy of its conservation status.

Skipjack tuna (Katsuwonus pelamis), should be managed properly because even though it is renewable, natural resources can be depleted. One approach in managing fish resources is by modeling. The purpose of this study is to determine the maximum sustainable yield, the level of utilization and effort of skipjack tuna. Data on catches as well as catch efforts of skipjack tuna were collected from 9 fisheries year books of Luwu Kabupaten (District). The surplus production model used is the Schaefer, Fox, Walter & Hilborn model. Schaefer model obtained by MSY = 1541.08 tons and Fopt = 243 trips; Fox model obtained maximum sustainable yield value (YMSY) of 1602,244 tons, maximum sustainable fishing effort (fMSY) of 303 units and maximum sustainable CpUE value (UMSY) of 5.29 tons trip-1; the Walter & Hilborn model found potential stocks of sustainable reserves (Be) skipjack in Luwu district amounted to 935.72 tons year-1. Utilization rates of the skpjack tuina indicate the fish is still under exploitation.

This essay reviews Hilton Als’ 2019 exhibition God Made My Face: A Collective Portrait of James Baldwin at the David Zwirner Gallery. The show visually displays Baldwin in two parts: “A Walker in the City” examines his biography and “Colonialism” examines “what Baldwin himself was unable to do” by displaying the work of contemporary artists and filmmakers whose works resonate with Baldwin’s critiques of masculinity, race, and American empire. Mirakhor explores how Als’ quest to restore Baldwin is part of a long and deep literary and personal conversation that Als has been having since he was in his teens, and in this instance, exploring why and how it has culminated via the visual, instead of the literary. As Mirakhor observes, to be in the exhibit is not to just observe how Als has formed and figured Baldwin, but to see how Baldwin has informed and made Als, one of our most lyrical and impassioned contemporary writers and thinkers.

This essay considers three paradigms of imitatio Christi in the later Middle Ages and their parallels in three modern American films. One paradigm is focused on Christ's physical suffering; a second, on Christ's human relationships, including aspects of his male sexuality; and the third, on Christ's teaching. The three paradigms are exemplified in illustrations from medieval manuscripts and other media and from texts such as Johannes de Caulibus's Meditationes vitae Christi (Meditations on the Life of Christ) and Walter Hilton's Scale of Perfection. The medieval paradigms are seen to survive in three modern American film biographies of Christ: Nicholas Ray's King of Kings (1961), Martin Scorsese's The Last Temptation of Christ (1997), and Mel Gibson's The Passion of the Christ (2004).

Surplus production models were used to assess the fishery condition of red seaweed Gelidium robustum off the west coast of the Baja California Peninsula from 1985 to 1997. The maximum sustainable yield and optimum effort estimated by the Schaefer model were 705 tn and 457 teams, while the Fox model estimated 670 tn and 510 teams. The determination coefficients were r2=0·62 for the Fox and r2=0·58 for the Schaefer model. These results suggest that the resource is not overexploited. Fitting the data to Hilborn & Walters' dynamic model was not satisfactory.

The last ten years have seen a growing disillusionment with many conventional fishery management methods, in part, I would suggest, since the managers using them have been unaware of the complexity of the ecosystems they are dealing with. The pendulum seems to be swinging steadily in the direction of spatially-based management tools for fisheries (see e.g. Hilborn & Kennedy 1992; Walters et al. 1993; Seijo et al. 1994; Hall 1998; Caddy 1999a), and the Mediterranean is ideally suited for testing and applying such mechanisms from both the geographical aspect, and in terms of its high biodiversity.

The whole spirit of Christian humanism, as exemplified by Erasmus, makes one think, in Mesnard’s phrase, of ‘mystique légère:’ plenty of of moralism and reformism, with less room for experience; a fruit of it was the Exercices of St Ignatius, in contrast with the alumbrados or even the Rheno-Flemish masters such as Eckhart or even Denys the Carthusian. More may not have so much as heard of Juliana of Norwich, England’s best-known medieval mystic, whereas he recommends Walter Hilton’s Scala perfectionis, and The Following of Christ, as he calls Thomas à Kempis’s classic. The earliest influences perceptible in his life and writings are Pico della Mirandola and John Colet. The Lutheran challenge led him to stress the role of human cooperation with God’s grace in the business of eternal salvation, and the essential role of the Church as interpreter of the Bible. Prison life with the imminence of a martyr’s death colored his meditation on the agony of Christ, and his stress on God as the only source of comfort.

<p>ABSTRACT<br />The resource utilization of mackerel scad (Decapterus spp.) has been increasing in Muna waters which will be able to reduce the fish stock and if it exceeds the carrying capacity, it will lead to "overfishing". This study aims to determine the level of production, fishing effort and the optimal economic chain, both biologically and economically, so that the management of fish resources in Muna waters can be carried out in a sustainable way. The study was conducted by the case study method. The analysis method used in this research is biotechnic; bioeconomy; static and dynamic optimization apprOAch of Walter-Hilbon (WH) estimation model. The results of the study provide an indicator that the mackerel scad in Muna waters has not experienced "overfishing" both biological and economic. MEY condition that is optimal for economic management will be achieved when the maximum effort as many as 213.734 trips, production amounted to 3.117,61 tons and maximum economic chain at IDR 33.434,41 billion. The amount of fishing effort in MSY condition within the model is 248.342 trips whereas the production amounted to 3.179,35 tons with the economic chain of IDR 32.557,81 billion. Results of biotechnic, bioeconomy, static and dynamic optimization showed that actual production is still below the sustainable production indicated by high production, effort and economic chain. Based on this analysis, the business effort of mackerel scad can be increased from the current fishing effort of 128.496 trips to 213.734 trips that will give the maximum economic chain and management of fish resources sustainably.</p><p><br />Keywords: bioeconomic, economic optimization, mackerel scad, resource management</p><p>-------</p><p><br />ABSTRAK</p><p>Pemanfaatan sumber daya ikan layang (Decapterus spp.) yang meningkat di perairan Kabupaten Muna dapat menurunkan stok ikan layang dan apabila melebihi daya dukung, maka akan menyebabkan terjadinya “overfishing”.

<p>Bali Strait has potential abundance of pelagic fishery resources such as Indonesian oil sardine (lemuru), frigate mackerel (tongkol), scad mackerel (layang), short-bodied mackerel (kembung) and others which can be caught mostly using purse seine. Fishery resources are combined and also known asmultispecies; therefore this research aimed to analyze the model of bio-economic multispecies exploitation of pelagic fishery resources in Bali Strait. The analytical methods that used in this research were estimated dynamic model of Walters and Hilborn (1976) and analysis of bio-economic model. The results showed that actual production of exploitation of pelagic fishery resources in Bali Strait, was lower than the rate of sustainable production especially Indonesian oil sardine and short-bodied mackerel. Production and fishing effort were below the actual optimal value. The management of pelagic fishery resources in Bali Strait did not show a good level of economic efficiency. Thus the exploitation of pelagic fishery resources in Bali Strait using purse seine could still be increased.</p><p><strong>Key words:</strong> bio-economic, multispecies, optimal</p>

ABSTRAKLaut Arafura merupakan salah satu perairan yang penting, sebesar 21% potensi ikan Indonesia terdapat di perairan Arafura yaitu 2,64 juta ton per tahun. Pemanfaatan sumber daya ikan demersal terutama udang di Laut Arafura telah dilakukan semenjak tahun 1970an oleh perusahaan dengan sistem joint venture. Penelitian ini bertujuan untuk mengetahui tingkat optimal pengelolaan sumber daya ikan demersal di Laut Arafura dan perubahan rente ekonomi setelah adanya kebijakan moratorium kapal asing di Indonesia yaitu pelarangan penggunaan kapal pukat dan kapal asing. Penelitian ini menggunakan data sekunder runtun waktu yang bersumber dari Kementerian Kelautan dan Perikanan, Badan PusatStatistik serta hasil-hasil penelitian yang relevan. Metode analisis data menggunakan model bioekonomi perikanan dengan model surplus produksi Walters dan Hilborn. Analisis kebijakan ekonomi meliputijumlah alat tangkap, jumlah investasi dan rente ekonomi maksimum. Jumlah produksi tertinggi terjadi ketika pengelolaan pada kondisi maksimum secara biologi; sedangkan jumlah alat tangkap tertinggiyang diperbolehkan ketika pengelolaan pada kondisi open akses menggunakan alat tangkap pancing rawai dasar, serta rente ekonomi tertinggi diperoleh ketika pengelolaan pada kondisi maksimum secara ekonomi menggunakan pancing rawai dasar. Kebijakan pemerintah terkait moratorium kapal perikanan asing, memberikan kesempatan lebih banyak untuk kapal perikanan Indonesia dalam melakukanpenangkapan ikan demersal di WPP 718. Jumlah kapal perikanan dengan menggunakan alat tangkap pancing rawai dasar dapat dikembangkan sampai 4 ribuan unit untuk memanfaatkan ikan demersal yangoptimal secara ekonomi, sehingga rente ekonomi maksimum dapat diperoleh sebesar 3,40 trilyun rupiah per tahun.Title: Management of Demersal Fishery in the Arafura Sea: A Bio-Economic ApproachABSTRACT Arafura sea is one of important fishing ground in Indonesia, contributing 21% of fisheries at about 2,64 million ton/year. Arafura’s demersal fishery has been exploited since 1970 by joint venture system. This study aims to determine the optimum level of demersal fish management in Arafura Sea as well as the fluctuations of economic rent after the foreign fishing vessel moratorium in Indonesia. The studycollected time series data from 2001-2014 from Ministry of Marine and Fisheries, Statistics Indonesia and relevant researches. The data were analyzed using bioeconomic model, particularly Walters and Hilborn Model. Analysis of economic policy includes fishing gears, investments and maximum economic rents. The results show that the maximum production occurs when fisheries management is on maximum yield. The highest number of permitted fishing gear is reached when the management is on open access condition using the set longline, while the maximum economic rents are obtained when the managementis on maximum economic yield using the set long line. Foreign fishing vessel moratorium gives more opportunity to Indonesian vessels to catch more demersal fish in WPP 718. The number of total optimum fishing vessel could be increased up to 4 thousand units in WPP 718 for demersal fishery in order reach optimum economic rent of 3.40 trillion rupiah per year.

Introdução: Lesões endoperiodontais são lesões originadas de produtos inflamatórios encontrados tanto em periodonto quanto em polpa. Tais lesões podem se originar devido a uma infecção pulpar ou periodontal. Visando o prognóstico favorável, é imprescindível o conhecimento da etiologia, realização do correto diagnóstico e elaboração do plano de tratamento que envolve o tratamento endodôntico precedido do tratamento periodontal. Objetivo: O propósito do presente trabalho foi de relatar um caso clínico de lesão endoperiodontal e o tratamento realizado. Relato de caso clínico: Paciente gênero feminino, 51 anos, compareceu à clínica com uma fístula na região do dente 46, procedeu-se com exame radiográfico, rastreamento de fístula, testes endodônticos e avaliação periodontal. Foi diagnosticada lesão endoperiodontal. Executou-se, então, o tratamento endodôntico em sessões múltiplas, utilizando hidróxido de cálcio como medicação intracanal e o tratamento periodontal concomitante; finalizou-se endodontia obturando-se os canais radiculares. Conclusão: Observou-se, no controle, que a associação de tratamentos foi eficaz e houve melhora significativa do quadro, constatando-se silêncio clínico e sucesso do tratamento.

Anna Z, Handaka AA, Maulina I, Rizal A, Hindayani P. 2017. Biological parameters of fish stock estimation in Cirata Reservoir (West Java, Indonesia): A comparative analysis of bio-economic models. Biodiversitas 18: 1468-1474. Fish resources in reservoirs such as Cirata have a strategic value, especially for the surrounding community in terms of fulfilling the need for nutricious food, subsistence, and economic purposes. Unfortunately, until now there has been no serious attention from the government to develop and manage fish resources in these waters. From time series data it can be seen that there is a decrease in fish production, which is an indication of a decrease of fish stock, which has a negative impact on the wellfare of surrounding commmunity, as well as the sustainability of fish resources and their ecosystems. To meet the food safety and economic needs of the community, a healthy and sustainable fish resource is a must, characterized by sustainable inputs and outputs, so that the stock of fish resources will be maintained. In order to fulfill this need, a basic understanding of the biological and economic conditions of the dynamics of fish resources in these waters as a basis for sustainable management is needed. Research was conducted to calculate the biological parameters of fish resources through Fox, CYP, Walters Hilborn and Schnute algorithms, using quarterly catch and effort data from 2011 to 2015, collected from secondary and cross checking data. Furthermore, using price and cost data series, adjusted by consumer price index, the variable of input, output and economic rent of sustainable, optimal and open access management regimes were analyzed. The results of the study indicate that the most statistically appropriate model for estimating biological parameters in Cirata are the Fox and CYP models, and fisheries management using the optimal regime provides the most efficient results, where fewer inputs will result in the maximum profit. The research suggests the need for immediate enforcement of management rules based on sustainable management regimes through input or output restrictions on capture fisheries in Cirata Reservoirs.

Ramularia leaf spot (RLS) is a disease of barley (Hordeum vulgare) caused by the fungus Ramularia collo-cygni Sutton & Waller (Rcc). Rcc causes necrotic lesions, premature senescence of leaves, and yield reduction. Under Estonian conditions, there are usually no leaf spots on the upper leaves of barley prior to flowering. In 2009, 2010, and 2012, symptoms similar to those of RLS were observed on leaves of spring and winter barley in several Estonian agricultural regions. Approximately 30% of the plants in affected fields were symptomatic. Symptoms were not observed in 2011, which was a dry and hot year. Initial symptoms were small brown spots, beginning on the upper leaves (flag leaf, F-1 leaf) at the flowering growth stage (4). Later, the spots spread to the sheaths, stems, and awns and became necrotic. The lateral margins of the spots were delimited by the leaf veins and spots are surrounded by a chlorotic halo. During summer 2012, two samples of 15 F-1 leaves were collected from spring barley cv. Maali and line SJ111609 from the Estonian Crop Research Institute in eastern Estonia in late July at growth stage 71 (4). In addition, six grain samples, containing 200 seeds each of the cv. Maali, were collected from different agricultural regions in Estonia, along with one grain sample of SJ111609 from Jõgeva. All samples were collected from untreated plots and leaves were observed under a dissecting microscope, revealing white clusters of conidiophores in rows on the undersides of the leaves. Conidia and conidiophores were scraped aseptically from the leaf surface using a sterile needle under a dissecting microscope and transferred to potato dextrose agar (PDA) containing ampicillin sodium salt (50 mg l−1). Plates were incubated at 18°C in the dark for 20 days until fungal mycelia were produced. The fungus was initially identified as Rcc on the basis of morphological characteristics (3). Colorless, 0- to 3-septate conidiophores were 15 to 17 × 2 to 5 μm, with a strongly curved end. Conidia were 7 to 11 × 3 to 6 μm, solitary, subglobose, single-celled, and of a darkish color. To confirm the presence of Rcc, DNA was extracted from the original barley leaf material, milled seeds, and positive control mycelia of Rcc grown on PDA using DNeasy Plant Mini Kit (Qiagen Gmbh, D-40724 Hilden, Germany) following manufacturer's guides. Rcc specific primers RC3 and RC5 (1) were used. A positive control consisting of 1 ng of purified Rcc DNA was included in the PCR. Standard PCR was conducted in a SEE AMP Seegene cycler. PCR were carried out in 20 μl volumes, containing 2 μl of DNA, 10 μl PCR mix, 0.4 μl each of forward and reverse Rcc primers, and 7.2 μl H2O. Qualitative detection analyzed by standard PCR with primers RC3 and RC5 revealed the presence of Rcc in symptomatic leaves and seeds. To complete Koch's postulates, a pathogenicity test was performed. Twenty-five barley seedlings were grown under controlled conditions (15°C/48 h dark, 16 h light/8 h dark, 70% RH) and spray-inoculated with a suspension of Rcc mycelium fragments as described by Macepeace et al. (2). The pathogen was re-isolated from leaves with necrotic lesions similar to those observed in the field, thus fulfilling Koch's postulates. To our knowledge, this is the first confirmed report of Ramularia leaf spot caused by Ramularia collo-cygni on barley in Estonia. References: (1) P. Frei et al. J. Phytopathol. 155:281, 2007. (2) J.

Why is it that we watch Mad Men and think it represents a period? Flashes of patterned wallpaper, whiskey neat, babies born that are never mentioned, contact lining for kitchen drawers, Ayn Rand, polaroids, skinny ties, Hilton hotels, Walter Cronkite, and a time when Don Draper can ask ‘What do women want?’ and dry old Roger Sterling can reply ‘Who Cares?’ This essay explores the embrace of period detail in Mad Men finding it to be both loving and fetishistic, and belonging, like all period film, to the politics of the present.

Being a celebrity sure ain’t what it used to be. Or, perhaps more accurately, the process of maintaining a stable star persona isn’t what it used to be. With the rise of new media technologies—including digital photography and video production, gossip blogging, social networking sites, and streaming video—there has been a rapid proliferation of voices which serve to articulate stars’ personae. This panoply of sanctioned and unsanctioned discourses has brought the coherence and stability of the star’s image into crisis, with an evermore-heightened loop forming recursively between celebrity gossip and scandals, on the one hand, and, on the other, new media-enabled speculation and commentary about these scandals and gossip-pieces. Of course, while no subject has a single meaning, Hollywood has historically expended great energy and resources to perpetuate the myth that the star’s image is univocal. In the present moment, however, studios’s traditional methods for discursive control have faltered, such that celebrities have found it necessary to take matters into their own hands, using new media technologies, particularly Twitter, in an attempt to stabilise that most vital currency of their trade, their professional/public persona. In order to fully appreciate the significance of this new mode of publicity management, and its larger implications for contemporary subjectivity writ large, we must first come to understand the history of Hollywood’s approach to celebrity publicity and image management.A Brief History of Hollywood PublicityThe origins of this effort are nearly as old as Hollywood itself, for, as Richard DeCordova explains, the celebrity scandals of the 1920s threatened to disrupt the economic vitality of the incipient industry such that strict, centralised image control appeared as a necessary imperative to maintain a consistently reliable product. The Fatty Arbuckle murder trial was scandalous not only for its subject matter (a murder suffused with illicit and shadowy sexual innuendo) but also because the event revealed that stars, despite their mediated larger-than-life images, were not only as human as the rest of us, but that, in fact, they were capable of profoundly inhuman acts. The scandal, then, was not so much Arbuckle’s crime, but the negative pall it cast over the Hollywood mythos of glamour and grace. The studios quickly organised an industry-wide regulatory agency (the MPPDA) to counter potentially damaging rhetoric and ward off government intervention. Censorship codes and morality clauses were combined with well-funded publicity departments in an effort that successfully shifted the locus of the star’s extra-filmic discursive construction from private acts—which could betray their screen image—to information which served to extend and enhance the star’s pre-existing persona. In this way, the sanctioned celebrity knowledge sphere became co-extensive with that of commercial culture itself; the star became meaningful only by knowing how she spent her leisure time and the type of make-up she used. The star’s identity was not found via unsanctioned intrusion, but through studio-sanctioned disclosure, made available in the form of gossip columns, newsreels, and fan magazines. This period of relative stability for the star's star image was ultimately quite brief, however, as the collapse of the studio system in the late 1940s and the introduction of television brought about a radical, but gradual, reordering of the star's signifying potential. The studios no longer had the resources or incentive to tightly police star images—the classic age of stardom was over. During this period of change, an influx of alternative voices and publications filled the discursive void left by the demise of the studios’s regimented publicity efforts, with many of these new outlets reengaging older methods of intrusion to generate a regular rhythm of vendible information about the stars.The first to exploit and capitalize on star image instability was Robert Harrison, whose Confidential Magazine became the leading gossip publication of the 1950s. Unlike its fan magazine rivals, which persisted in portraying the stars as morally upright and wholesome, Confidential pledged on the cover of each issue to “tell the facts and name the names,” revealing what had been theretofore “confidential.” In essence, through intrusion, Confidential reasserted scandal as the true core of the star, simultaneously instituting incursion and surveillance as the most direct avenue to the “kernel” of the celebrity subject, obtaining stories through associations with call girls, out-of-work starlettes, and private eyes. As extra-textual discourses proliferated and fragmented, the contexts in which the public encountered the star changed as well. Theatre attendance dropped dramatically, and as the studios sold their film libraries to television, the stars, formerly available only on the big screen and in glamour shots, were now intercut with commercials, broadcast on grainy sets in the domestic space. The integrity—or at least the illusion of integrity—of the star image was forever compromised. As the parameters of renown continued to expand, film stars, formally distinguished from all other performers, migrated to television. The landscape of stardom was re-contoured into the “celebrity sphere,” a space that includes television hosts, musicians, royals, and charismatic politicians. The revamped celebrity “game” was complex, but still playabout: with a powerful agent, a talented publicist, and a check on drinking, drug use, and extra-marital affairs, a star and his or her management team could negotiate a coherent image. Confidential was gone, The National Inquirer was muzzled by libel laws, and People and E.T.—both sheltered within larger media companies—towed the publicists’s line. There were few widely circulated outlets through which unauthorised voices could gain traction. Old-School Stars and New Media Technologies: The Case of Tom CruiseYet with the relentless arrival of various news media technologies beginning in the 1980s and continuing through the present, maintaining tight celebrity image control began to require the services of a phalanx of publicists and handlers. Here, the example of Tom Cruise is instructive: for nearly twenty years, Cruise’s publicity was managed by Pat Kingsley, who exercised exacting control over the star’s image. With the help of seemingly diverse yet essentially similar starring roles, Cruise solidified his image as the cocky, charismatic boy-next-door.The unified Cruise image was made possible by shutting down competing discourses through the relentless, comprehensive efforts of his management company; Kingsley's staff fine-tuned Cruise’s acts of disclosure while simultaneously eliminating the potential for unplanned intrusions, neutralising any potential scandal at its source. Kingsley and her aides performed for Cruise all the functions of a studio publicity department from Hollywood’s Golden Age. Most importantly, Cruise was kept silent on the topic of his controversial religion, Scientology, lest it incite domestic and international backlash. In interviews and off-the-cuff soundbites, Cruise was ostensibly disclosing his true self, and that self remained the dominant reading of what, and who, Cruise “was.” Yet in 2004, Cruise fired Kingsley, replaced her with his own sister (and fellow Scientologist), who had no prior experience in public relations. In essence, he exchanged a handler who understood how to shape star disclosure for one who did not. The events that followed have been widely rehearsed: Cruise avidly pursued Katie Holmes; Cruise jumped for joy on Oprah’s couch; Cruise denounced psychology during a heated debate with Matt Lauer on The Today Show. His attempt at disclosing this new, un-publicist-mediated self became scandalous in and of itself. Cruise’s dismissal of Kingsley, his unpopular (but not necessarily unwelcome) disclosures, and his own massively unchecked ego all played crucial roles in the fall of the Cruise image. While these stumbles might have caused some minor career turmoil in the past, the hyper-echoic, spastically recombinatory logic of the technoculture brought the speed and stakes of these missteps to a new level; one of the hallmarks of the postmodern condition has been not merely an increasing textual self-reflexivity, but a qualitative new leap forward in inter-textual reflexivity, as well (Lyotard; Baudrillard). Indeed, the swift dismantling of Cruise’s long-established image is directly linked to the immediacy and speed of the Internet, digital photography, and the gossip blog, as the reflexivity of new media rendered the safe division between disclosure and intrusion untenable. His couchjumping was turned into a dance remix and circulated on YouTube; Mission Impossible 3 boycotts were organised through a number of different Web forums; gossip bloggers speculated that Cruise had impregnated Holmes using the frozen sperm of Scientology founder L. Ron Hubbard. In the past, Cruise simply filed defamation suits against print publications that would deign to sully his image. Yet the sheer number of sites and voices reproducing this new set of rumors made such a strategy untenable. Ultimately, intrusions into Cruise’s personal life, including the leak of videos intended solely for Scientology recruitment use, had far more traction than any sanctioned Cruise soundbite. Cruise’s image emerged as a hollowed husk of its former self; the sheer amount of material circulating rendered all attempts at P.R., including a Vanity Fair cover story and “reveal” of daughter Suri, ridiculous. His image was fragmented and re-collected into an altered, almost uncanny new iteration. Following the lackluster performance of Mission Impossible 3 and public condemnation by Paramount head Sumner Redstone, Cruise seemed almost pitiable. The New Logic of Celebrity Image ManagementCruise’s travails are expressive of a deeper development which has occurred over the course of the last decade, as the massively proliferating new forms of celebrity discourse (e.g., paparazzi photos, mug shots, cell phone video have further decentered any shiny, polished version of a star. With older forms of media increasingly reorganising themselves according to the aesthetics and logic of new media forms (e.g., CNN featuring regular segments in which it focuses its network cameras upon a computer screen displaying the CNN website), we are only more prone to appreciate “low media” forms of star discourse—reports from fans on discussion boards, photos taken on cell phones—as valid components of the celebrity image. People and E.T. still attract millions, but they are rapidly ceding control of the celebrity industry to their ugly, offensive stepbrothers: TMZ, Us Weekly, and dozens of gossip blogs. Importantly, a publicist may be able to induce a blogger to cover their client, but they cannot convince him to drop a story: if TMZ doesn’t post it, then Perez Hilton certainly will. With TMZ unabashedly offering pay-outs to informants—including those in law enforcement and health care, despite recently passed legislation—a star is never safe. If he or she misbehaves, someone, professional or amateur, will provide coverage. Scandal becomes normalised, and, in so doing, can no longer really function as scandal as such; in an age of around-the-clock news cycles and celebrity-fixated journalism, the only truly scandalising event would be the complete absence of any scandalous reports. Or, as aesthetic theorist Jacques Ranciere puts it; “The complaint is then no longer that images conceal secrets which are no longer such to anyone, but, on the contrary, that they no longer hide anything” (22).These seemingly paradoxical involutions of post-modern celebrity epistemologies are at the core of the current crisis of celebrity, and, subsequently, of celebrities’s attempts to “take back their own paparazzi.” As one might expect, contemporary celebrities have attempted to counter these new logics and strategies of intrusion through a heightened commitment to disclosure, principally through the social networking capabilities of Twitter. Yet, as we will see, not only have the epistemological reorderings of postmodernist technoculture affected the logic of scandal/intrusion, but so too have they radically altered the workings of intrusion’s dialectical counterpart, disclosure.In the 1930s, when written letters were still the primary medium for intimate communication, stars would send lengthy “hand-written” letters to members of their fan club. Of course, such letters were generally not written by the stars themselves, but handwriting—and a star’s signature—signified authenticity. This ritualised process conferred an “aura” of authenticity upon the object of exchange precisely because of its static, recurring nature—exchange of fan mail was conventionally understood to be the primary medium for personal encounters with a celebrity. Within the overall political economy of the studio system, the medium of the hand-written letter functioned to unleash the productive power of authenticity, offering an illusion of communion which, in fact, served to underscore the gulf between the celebrity’s extraordinary nature and the ordinary lives of those who wrote to them. Yet the criterion and conventions through which celebrity personae were maintained were subject to change over time, as new communications technologies, new modes of Hollywood's industrial organization, and the changing realities of commercial media structures all combined to create a constantly moving ground upon which the celebrity tried to affix. The celebrity’s changing conditions are not unique to them alone; rather, they are a highly visible bellwether of changes which are more fundamentally occurring at all levels of culture and subjectivity. Indeed, more than seventy years ago, Walter Benjamin observed that when hand-made expressions of individuality were superseded by mechanical methods of production, aesthetic criteria (among other things) also underwent change, rendering notions of authenticity increasingly indeterminate.Such is the case that in today’s world, hand-written letters seem more contrived or disingenuous than Danny DeVito’s inaugural post to his Twitter account: “I just joined Twitter! I don't really get this site or how it works. My nuts are on fire.” The performative gesture in DeVito’s tweet is eminently clear, just as the semantic value is patently false: clearly DeVito understands “this site,” as he has successfully used it to extend his irreverent funny-little-man persona to the new medium. While the truth claims of his Tweet may be false, its functional purpose—both effacing and reifying the extraordinary/ordinary distinction of celebrity and maintaining DeVito’s celebrity personality as one with which people might identify—is nevertheless seemingly intact, and thus mirrors the instrumental value of celebrity disclosure as performed in older media forms. Twitter and Contemporary TechnocultureFor these reasons and more, considered within the larger context of contemporary popular culture, celebrity tweeting has been equated with the assertion of the authentic celebrity voice; celebrity tweets are regularly cited in newspaper articles and blogs as “official” statements from the celebrity him/herself. With so many mediated voices attempting to “speak” the meaning of the star, the Twitter account emerges as the privileged channel to the star him/herself. Yet the seemingly easy discursive associations of Twitter and authenticity are in fact ideological acts par excellence, as fixations on the indexical truth-value of Twitter are not merely missing the point, but actively distracting from the real issues surrounding the unsteady discursive construction of contemporary celebrity and the “celebretification” of contemporary subjectivity writ large. In other words, while it is taken as axiomatic that the “message” of celebrity Twittering is, as Henry Jenkins suggests, “Here I Am,” this outward epistemological certainty veils the deeply unstable nature of celebrity—and by extension, subjectivity itself—in our networked society.If we understand the relationship between publicity and technoculture to work as Zizek-inspired cultural theorist Jodi Dean suggests, then technologies “believe for us, accessing information even if we cannot” (40), such that technology itself is enlisted to serve the function of ideology, the process by which a culture naturalises itself and attempts to render the notion of totality coherent. For Dean, the psycho-ideological reality of contemporary culture is predicated upon the notion of an ever-elusive “secret,” which promises to reveal us all as part of a unitary public. The reality—that there is no such cohesive collective body—is obscured in the secret’s mystifying function which renders as “a contingent gap what is really the fact of the fundamental split, antagonism, and rupture of politics” (40). Under the ascendancy of the technoculture—Dean's term for the technologically mediated landscape of contemporary communicative capitalism—subjectivity becomes interpellated along an axis blind to the secret of this fundamental rupture. The two interwoven poles of this axis are not unlike structuralist film critics' dialectically intertwined accounts of the scopophilia and scopophobia of viewing relations, simply enlarged from the limited realm of the gaze to encompass the entire range of subjectivity. As such, the conspiratorial mindset is that mode of desire, of lack, which attempts to attain the “secret,” while the celebrity subject is that element of excess without which desire is unthinkable. As one might expect, the paparazzi and gossip sites’s strategies of intrusion have historically operated primarily through the conspiratorial mindset, with endless conjecture about what is “really happening” behind the scenes. Under the intrusive/conspiratorial paradigm, the authentic celebrity subject is always just out of reach—a chance sighting only serves to reinscribe the need for the next encounter where, it is believed, all will become known. Under such conditions, the conspiratorial mindset of the paparazzi is put into overdrive: because the star can never be “fully” known, there can never be enough information about a star, therefore, more information is always needed. Against this relentless intrusion, the celebrity—whose discursive stability, given the constant imperative for newness in commercial culture, is always in danger—risks a semiotic liquidation that will totally displace his celebrity status as such. Disclosure, e.g. Tweeting, emerges as a possible corrective to the endlessly associative logic of the paparazzi’s conspiratorial indset. In other words, through Twitter, the celebrity seeks to arrest meaning—fixing it in place around their own seemingly coherent narrativisation. The publicist’s new task, then, is to convincingly counter such unsanctioned, intrusive, surveillance-based discourse. Stars continue to give interviews, of course, and many regularly pose as “authors” of their own homepages and blogs. Yet as posited above, Twitter has emerged as the most salient means of generating “authentic” celebrity disclosure, simultaneously countering the efforts of the papparazzi, fan mags, and gossip blogs to complicate or rewrite the meaning of the star. The star uses the account—verified, by Twitter, as the “real” star—both as a means to disclose their true interior state of being and to counter erastz narratives circulating about them. Twitter’s appeal for both celebrities and their followers comes from the ostensible spontaneity of the tweets, as the seemingly unrehearsed quality of the communiqués lends the form an immediacy and casualness unmatched by blogs or official websites; the semantic informality typically employed in the medium obscures their larger professional significance for celebrity tweeters. While Twitter’s air of extemporary intimacy is also offered by other social networking platforms, such as MySpace or Facebook, the latter’s opportunities for public feedback (via wall-posts and the like) works counter to the tight image control offered by Twitter’s broadcast-esque model. Additionally, because of the uncertain nature of the tweet release cycle—has Ashton Kutcher sent a new tweet yet?—the voyeuristic nature of the tweet disclosure (with its real-time nature offering a level of synchronic intimacy that letters never could have matched), and the semantically displaced nature of the medium, it is a form of disclosure perfectly attuned to the conspiratorial mindset of the technoculture. As mentioned above, however, the conspiratorial mindset is an unstable subjectivity, insofar as it only exists through a constant oscillation with its twin, the celebrity subjectivity. While we can understand that, for the celebrities, Twitter functions by allowing them a mode for disclosive/celebrity subjectivisation, we have not yet seen how the celebrity itself is rendered conspiratorial through Twitter. Similarly, only the conspiratorial mode of the follower’s subjectivity has thus far been enumerated; the moment of the follower's celebrtification has so far gone unmentioned. Since we have seen that the celebrity function of Twitter is not really about discourse per se, we should instead understand that the ideological value of Twitter comes from the act of tweeting itself, of finding pleasure in being engaged in a techno-social system in which one's participation is recognised. Recognition and participation should be qualified, though, as it is not the fully active type of participation one might expect in say, the electoral politics of a representative democracy. Instead, it is a participation in a sort of epistemological viewing relations, or, as Jodi Dean describes it, “that we understand ourselves as known is what makes us think there is that there is a public that knows us” (122). The fans’ recognition by the celebrity—the way in which they understood themselves as known by the star was once the receipt of a hand-signed letter (and a latent expectation that the celebrity had read the fan’s initial letter); such an exchange conferred to the fan a momentary sense of participation in the celebrity's extraordinary aura. Under Twitter, however, such an exchange does not occur, as that feeling of one-to-one interaction is absent; simply by looking elsewhere on the screen, one can confirm that a celebrity's tweet was received by two million other individuals. The closest a fan can come to that older modality of recognition is by sending a message to the celebrity that the celebrity then “re-tweets” to his broader following. Beyond the obvious levels of technological estrangement involved in such recognition is the fact that the identity of the re-tweeted fan will not be known by the celebrity’s other two million followers. That sense of sharing in the celebrity’s extraordinary aura is altered by an awareness that the very act of recognition largely entails performing one’s relative anonymity in front of the other wholly anonymous followers. As the associative, conspiratorial mindset of the star endlessly searches for fodder through which to maintain its image, fans allow what was previously a personal moment of recognition to be transformed into a public one. That is, the conditions through which one realises one’s personal subjectivity are, in fact, themselves becoming remade according to the logic of celebrity, in which priority is given to the simple fact of visibility over that of the actual object made visible. Against such an opaque cultural transformation, the recent rise of reactionary libertarianism and anti-collectivist sentiment is hardly surprising. ReferencesBaudrillard, Jean.
