IoT systems can be leveraged by Network Function Virtualization (NFV) and Software-Defined Networking (SDN) technologies, thereby strengthening their overall flexibility, security and resilience. In this sense, adaptive and policy-based security frameworks for SDN/NFV-aware IoT systems can provide a remarkable added value for self-protection and self-healing, by orchestrating and enforcing dynamically security policies and associated Virtual Network Functions (VNF) or Virtual network Security Functions (VSF) according to the actual context. However, this security orchestration is subject to multiple possible inconsistencies between the policies to enforce, the already enforced management policies and the evolving status of the managed IoT system. In this regard, this paper presents a semantic-aware, zero-touch and policy-driven security orchestration framework for autonomic and conflict-less security orchestration in SDN/NFV-aware IoT scenarios while ensuring optimal allocation and Service Function Chaining (SFC) of VSF. The framework relies on Semantic technologies and considers the security policies and the evolving IoT system model to dynamically and formally detect any semantic conflict during the orchestration. In addition, our optimized SFC algorithm maximizes the QoS, security aspects and resources usage during VSF allocation. The orchestration security framework has been implemented and validated showing its feasibility and performance to detect the conflicts and optimally enforce the VSFs.

Longing on a large scale is what makes history.Don DeLillo, UnderworldIntroductionWhile the media industries have been rather thoroughly dissected for their capacity to generate enthusiasm through well-honed practices of marketing and patterns of consumerism, any analysis of the shift underway to capture and modulate the ‘enthusiastic’ and affective labour of media industry practitioners themselves may still have much to learn by reaching back to the long tradition in Western philosophy: a tradition, starting with the Greeks that has almost always contrasted enthusiasm with reason (Heyd). To quote Hume: “Hope, pride, presumption, a warm imagination, together with ignorance, are … the true sources of enthusiasm” (73). Hume’s remarks are contextualised in protestant theological debates of the 18th century, where enthusiasm was a term for a religious practice, in which God possesses the believer. Especially English preachers and theologians were putting considerable energy into demonising this far too ecstatic form of belief in god (Heyd). This ambivalent attitude towards enthusiasm time-travels from the Greeks and the Enlightenment period straight into the 20th century. In 1929, William Henry Schoenau, an early author of self-help literature for the white-collar worker, aimed to gain a wider audience with the title: “Charm, Enthusiasm and Originality - their Acquisition and Use”. According to him, enthusiasm is necessary for the success of the salesman, and has to be generated by techniques such as a rigorous special diet and physical exercises of his facial muscles. But it also has to be controlled:Enthusiasm, when controlled by subtle repression, results in either élan, originality, magnetism, charm or “IT”, depending on the manner of its use. Uncontrolled enthusiasm results in blaring jazz, fanaticism and recklessness. A complete lack of enthusiasm produces the obsequious waiter and the uneducated street car conductor. (7)Though William Henry Schoenau got rather lost in his somewhat esoteric take on enthusiasm – for him it was a result of magnetic and electric currents – we argue that Schoenau had a point: Enthusiasm is a necessary affect in many forms of work, and especially so in the creative industries. It has to be generated, it sometimes has to be enacted, and it has also to be controlled. However, we disagree with Schoenau in one important issue: For us, enthusiasm can only be controlled up to a certain degree. Enthusiasm in the Creative IndustriesSchoenau wrote for an audience of salesmen and ambitious managers. This was simultaneous with the rise of Fordism. Most labour in Fordism was routine labour with the assembly line as its iconic representation. In mass-production itself, enthusiasm was not needed, often not even wanted. Henry Ford himself noted dryly: “Why do I get a human being when all I want is a pair of hands” (Kane 128). It was reserved for few occupational groups situated around the core of the mass-produced economy, such as salesmen, inventors, and leaders like him. “Henry Ford had a burning enthusiasm for the motor car” (Pearle 196).In industrial capitalism enthusiasm on a larger scale was not for the masses. It could be found in political movements, but hardly in the realm of work. This was different in the first socialist state. In the 1920s and 1930s Soviet Union the leaders turned their experience in stimulating a revolutionary mindset into a formula for industrial development – famously documented in Dziga Vertov’s “Enthusiasm. Symphony of the Donbass”.In capitalist countries things changed with the crisis of Fordism. The end of mass production and its transformation to flexible specialisation (Piore/Sabel) prepared the ground for a revival of enthusiasm on a large scale. Post-industrial economies rely on permanent innovation. Now discourses in media, management, and academia emphasise the relevance of buzzwords such as flexibility, adaptability, change, youth, speed, fun, and creativity. In social science debates around topics such as the cultural economy (Ray/Sayers, Cook et al., du Gay/Pryke, Amin/Thrift), affective labour (Lazzarato, Hardt/Negri, Virno) and creative industries (Florida, Hartley) gained in momentum (for an interesting take on enthusiasm see Bröckling). Enthusiasm has become an imperative for most professions. Those who are not on fire are in danger of getting fired. Producing and Consuming EnthusiasmOur interest in enthusiasm as affective labour emerged in an ethnographic and experimental project that we conducted in 2003-2007 in London’s creative industries. The project brought together three industrial and one academic partner to produce a reality TV show tailor-made for IPTV (internet-protocol-based television). During this project we encountered enthusiasm in many forms. Initially, we were faced with the need to be enthusiastic, while we established the project coalition. To be convincing, we had to pitch the commercial potential of such a project enthusiastically to our potential partners, and often we had to cope with rejections and start the search and pitch again (Caldwell). When the project coalition was set up, we as academic partners managed the network. In the following two years we had to cope with our partner’s different directions, different rhythms and different styles of enthusiasm. The TV producer for example had different ways to express excitement than the new media firm. Such differences resulted in conflicts and blockades, and part of our task as project managers was to rebuild an enthusiastic spirit after periods of frustration. At the same time enthusiasm was one of the ingredients of the digital object that we produced: `Real’ emotions form the material of most reality TV shows (Grindstaff). Affects are for reality TV, what steel was for a Fordist factory. We needed an enthusiastic audience as part of the filmed material. There is thus a need to elicit, select, engineer and film such emotions. To this aim we engaged with the participants and the audience in complex ways, sometimes by distancing ourselves, other times by consciously manipulating them, and at even other times by sharing enthusiasm (similar processes in respect to other emotions are ethnographically described in Hesmondhalgh/Baker). Generating and managing enthusiasm is obviously a necessary part of affective labour in the creative industries. However, just as Hesmondhalgh/Baker indicate, this seemingly simple claim is problematic.Affective Labour as Practice‘Affective labour’ is a term that describes labour through its products: ‘A feeling of ease, well-being, satisfaction, excitement, or passion’ (Hardt/Negri 292-293). Thus, the term ‘affective labour’ usually describes a sector by the area of human endeavour, which it commodifies. But the concept looses its coherence, if it is used to describe labour by its practice (for an analogue argument see Dowling). The latter is what interests us. Such a usage will have to re-introduce the notion of the working subject. To see affective labour as a practice should enable us to describe in more detail, how enthusiasm shapes the becoming of a cultural object. Who employed affect when and what kinds of affects in which way? Analysing enthusiasm as social practice and affective labour usually brings about one of two contrasting perceptions. On the one hand one can celebrate enthusiasm – like Pekka Himanen – as one of the key characteristics for a new work ethic emerging alongside the Protestant Ethic. On the other hand we find critique of the need to display affects. Barbara Ehrenreich shows how a forced display of enthusiasm becomes a requirement for all office workers to survive in late capitalism. Judging from our experience these two approaches need to be synthesized: Much affective labour consists in the display of affects, in showing off, in pretending. On the other hand, enthusiasm can only realise its potential, if it is ‘real’ (as opposed to enacted).With Ehrenreich, Hochschild and many others we think that an analysis of affective labour as a practice needs to start with a notion of expression. Enthusiasm can be expressed through excited gestures, rapid movements, raised voices, eyes wide open, clapping hands, speech. For us it was often impossible to separate which expression was ‘genuine’ and which was enacted. Judging from introspection, it is probable that many actors had a similar experience to ours: They mixed some genuine enthusiasm with more or less enforced forms of re-enactment. Perhaps re-enactment turned to a ‘real’ feeling: We enacted ourselves into an authentic mood - an effect that is also described as “deep acting” (Grandey). What can happen inside us, can also happen in social situations. German philosopher Max Scheler went to substantial lengths to make a case for the contagiousness of affects, and enthusiasm is one of the most contagious affects. Mutual contagiousness of enthusiasm can lead to collective elation, with or without genuine enthusiasm of all members. The difference of real, authentic affects and enacted affects is thus not only theoretically, but also empirically rather problematic. It is impossible to make convincing claims about the degree of authenticity of an affect. However, it is also impossible to ignore this ambivalence. Both ‘authentic’ and ‘faked’ enthusiasm can be affective labour, but they differ hugely in terms of their productive capacities.Enthusiasm as Productive ForceWhy is enthusiasm so important in the first place? The answer is threefold. Firstly, an enthusiastic worker is more productive. He or she will work more intensively, put in more commitment, is likely to go the so-called extra mile. Enthusiasm can create a surplus of labour and a surplus of value, thus a surplus of productivity. Secondly enthusiasm is part of the creative act. It can unleash energies and overcome self-imposed limitations. Thirdly enthusiasm is future-oriented, a stimulus for investment, always risky. Enthusiasm can be the affective equivalent of venture capital – but it is not reified in capital, but remains incorporated in labour. Thus enthusiasm not only leads to an increase of productivity, it can be productive itself. This is what makes it to one of the most precious commodities in the creative industries. To make this argument in more detail we need to turn to one of the key philosophers of affect.Thinking Enthusiasm with SpinozaFor Spinoza, all affects are derivatives of a first basic drive or appetite. Desire/appetite is the direct equivalent of what Spinoza calls Conatus: Our striving to increase our power. From this starting point, Spinoza derives two basic affects: pleasure/joy and sadness/pain. Pleasure/joy is the result of an increase of our power, and sadness/pain is the result of its decrease. Spinoza explains all other affects through this basic framework. Even though enthusiasm is not one of the affects that Spinoza mentions, we want to suggest that Spinoza’s approach enables us to understand the productivity of enthusiasm. Enthusiasm is a hybrid between desire (the drive) and joy (the basic affect). Like hope or fear, it is future-oriented. It is a desire (to increase our power) combined with an anticipated outcome. Present and the future are tightly bound. Enthusiasm differs in this respect from its closest relatives: hope and optimism. Both hope and optimism believe in the desired outcome, but only against the odds and with a presumption of doubt. Enthusiasm is a form of ecstatic and hyper-confident hope. It already rewards us with joy in the present.With Spinoza we can understand the magical trick of future-oriented enthusiasm: To be enthusiastic means to anticipate an outcome of an increased power. This anticipation increases our power in the present. The increased power in the present can then be used to achieve the increased power in the future. If successful, it becomes a self-fulfilling prophecy. It is this future-orientedness, which can make enthusiasm productive. Actions and PassionsIn its Greek origin (‘enthousiasmos’) to be enthusiastic meant to be possessed or inspired by a god. An enthusiast was someone with an intense religious fervour and sometimes someone with an exaggerated belief in religious inspiration. Accordingly, enthusiasm is often connected to the devotion to an ideal, cause, study or pursuit. In late capitalism, we get possessed by different gods. We get possessed by the gods of opportunity – in our case the opportunities of a new technology like IPTV. Obsessions cannot easily be switched on and off. This is part of affective labour: The ability to open up and let the gods of future-oriented enthusiasm take hold of us. We believe in something not for the sake of believing, but for the sake of what we believe in. But at the same time we know that we need to believe. The management of this contradiction is a problem of control. As enthusiasm now constitutes a precious commodity, we cannot leave it to mere chance. Spinoza addresses exactly this point. He distinguishes two kinds of affects, actions and passions. Actions are what we control, passions are what controls us. Joy (= the experience of increased power of acting) can also weaken, if someone is not able to control the affection that triggered the joy. In such a case it becomes a passion: An increase of power that weakens in the long run. Enthusiasm is often exactly this. How can enthusiasm as a passion be turned into an action? One possible answer is to control what Spinoza calls the ‘ideas’ of the bodily affections. For Spinoza, affections (affectiones) ‘strike’ the body, but affect (affectus) is formed of both, of the bodily affectiones, but also of our ideas of these affectiones. Can such ideas become convictions, beliefs, persuasions? Our experience suggests that this is indeed possible. The excitement about the creative possibilities of IPTV, for example, was turned into a conviction. We had internalised the affect as part of our beliefs. But we had internalised it for a prize: The more it became an idea the more stable it got, but the less it was a full, bodily affect, something that touched our nervous system. We gained power over it for the price that it became less powerful in its drive.Managing the UnmanageableIn all institutions and organisations enthusiasm needs to be managed on a regular basis. In project networks however the orchestration of affects faces a different set of obstacles than in traditional organizations. Power structures are often shifting and not formally defined. Project partners are likely to have diverging interests, different expectations and different views on how to collaborate. What might be a disappointing result for one partner can be a successful result for another one. Differences of interest can be accompanied by differences of the expression of enthusiasm. This was clearly the case in our project network. The TV company entered a state of hype and frenzy while pitching the project. They were expressing their enthusiasm with talk about prominent TV channels that would buy the product, and celebrities who would take part in the show. The new media company showed its commitment through the development of beautifully designed time plans and prototypes – one of them included the idea to advertise the logo of the project on banners placed on airplanes. This sort of enthusiastic presentation led the TV producer to oppose the vision of the new media’s brand developer: She perceived this as an example of unrealistic pipe dreams. In turn the TV producer’s repeated name-dropping led other partners to mistrust them.Timing was another reason why it seemed to be impossible to integrate the affective cohorts of all partners into one well-oiled machine. Work in TV production requires periods of heightened enthusiasm while shooting the script. Not surprisingly, TV professionals save up their energy for this time. In contrast, new media practitioners create their products on the go: hype and energy are spread over the whole work process. Their labour becomes materialised in detailed plans, concepts, and prototypes. In short, the affective machine of a project network needs orchestration. This is a question of management.As this management failed so often in our project, we could discover another issue in the universe of enthusiasm: Disappointed high spirits can easily turn into bitterness and hostility. High expectations can lead to a lack of motivation and finally to a loss of loyalty towards the product and towards other project partners. Thus managing enthusiasm is not just about timing. It is also about managing disappointment and frustration. These are techniques, which have to be well developed on the level of the self-management as well as group management.Beyond the ProjectWe want to conclude this paper with a scene that happened at the very end of the project. In a final meeting, all partners agreed – much to our surprise – that the product was a big success. At that time we as academic partners found this irritating. There were many reasons why we disagreed: we did not produce a new format, we did not get positive user feedback, and we could not sell the show to further broadcasters (our original aims). However, all of this did not seem to have any impact on this final assessment. At the time of the meeting this looked for us like surreal theatre. Looking back now, this display of enthusiasm was indeed perhaps a ‘rational’ thing to do. Most projects and products in the creative industries are not successful on the market (Frith). To recreate the belief that one will eventually be successful (McRobbie) seems to be the one task of affective labour that stands out at the end of the lifecycle of many creative project networks.References Amin, Ash, and Nigel Thrift, eds.

Introduction A snapshot, not unlike countless photographs likely to be found in any number of family albums, shows two figures sitting on a park bench: an elderly and amiable looking man grins beneath the rim of a golf cap; a young boy of twelve smiles wide for the camera — a rather banal scene, captured on film. And yet, this seemingly innocent and unexceptional photograph was the site of a remarkable and wide ranging discourse — encompassing American conservatism, celebrity politics, and the end of the Cold War — as the image circulated around the globe during the weeklong state funeral of Ronald Wilson Reagan, 40th president of the United States. Taken in 1997 by the young boy’s grandfather, Ukrainian immigrant Yakov Ravin, during a chance encounter with the former president, the snapshot is believed to be the last public photograph of Ronald Reagan. Published on the occasion of the president’s death, the photograph made “instant celebrities” of the boy, now a twenty-year-old college student, Rostik Denenburg and his grand dad. Throughout the week of Reagan’s funeral, the two joined a chorus of dignitaries, politicians, pundits, and “ordinary” Americans praising Ronald Reagan: “The Great Communicator,” the man who defeated Communism, the popular president who restored America’s confidence, strength, and prosperity. Yes, it was mourning in America again. And the whole world was watching. Not since Princess Diana’s sudden (and unexpected) death, have we witnessed an electronic hagiography of such global proportions. Unlike Diana’s funeral, however, Reagan’s farewell played out in distinctly partisan terms. As James Ridgeway (2004) noted, the Reagan state funeral was “not only face-saving for the current administration, but also perhaps a mask for the American military debacle in Iraq. Not to mention a gesture of America’s might in the ‘war on terror.’” With non-stop media coverage, the weeklong ceremonies provided a sorely needed shot in the arm to the Bush re-election campaign. Still, whilst the funeral proceedings and the attendant media coverage were undeniably excessive in their deification of the former president, the historical white wash was not nearly so vulgar as the antiseptic send off Richard Nixon received back in 1994. That is to say, the piety of the Nixon funeral was at once startling and galling to many who reviled the man (Lapham). By contrast, given Ronald Reagan’s disarming public persona, his uniquely cordial relationship with the national press corps, and most notably, his handler’s mastery of media management techniques, the Reagan idolatry was neither surprising nor unexpected. In this brief essay, I want to consider Reagan’s funeral, and his legacy, in relation to what cultural critics, referring to the production of celebrity, have described as “fame games” (Turner, Bonner & Marshall). Specifically, I draw on the concept of “flashpoints” — moments of media excess surrounding a particular personage — in consideration of the Reagan funeral. Throughout, I demonstrate how Reagan’s death and the attendant media coverage epitomize this distinctive feature of contemporary culture. Furthermore, I observe Reagan’s innovative approaches to electoral politics in the age of television. Here, I suggest that Reagan’s appropriation of the strategies and techniques associated with advertising, marketing and public relations were decisive, not merely in terms of his electoral success, but also in securing his lasting fame. I conclude with some thoughts on the implications of Reagan’s legacy on historical memory, contemporary politics, and what neoconservatives, the heirs of the Reagan Revolution, gleefully describe as the New American Century. The Magic Hour On the morning of 12 June 2004, the last day of the state funeral, world leaders eulogized Reagan, the statesmen, at the National Cathedral in Washington, D.C. Among the A-List political stars invited to speak were Margaret Thatcher, former president George H. W. Bush and, to borrow Arundhati Roi’s useful phrase, “Bush the Lesser.” Reagan’s one-time Cold War adversary, Mikhail Gorbachev, as well as former Democratic presidents, Jimmy Carter and Bill Clinton were also on hand, but did not have speaking parts. Former Reagan administration officials, Supreme Court justices, and congressional representatives from both sides of the aisle rounded out a guest list that read like a who’s who of the American political class. All told, Reagan’s weeklong sendoff was a state funeral at its most elaborate. It had it all—the flag draped coffin, the grieving widow, the riderless horse, and the procession of mourners winding their way through the Rotunda of the US Capitol. In this last regard, Reagan joined an elite group of seven presidents, including four who died by assassination — Abraham Lincoln, James Garfield, William McKinley and John F. Kennedy — to be honored by having his remains lie in state in the Rotunda. But just as the deceased president was product of the studio system, so too, the script for the Gipper’s swan song come straight out of Hollywood. Later that day, the Reagan entourage made one last transcontinental flight back to the presidential library in Simi Valley, California for a private funeral service at sunset. In Hollywood parlance, the “magic hour” refers to the quality of light at dusk. It is an ideal, but ephemeral time favored by cinematographers, when the sunlight takes on a golden glow lending grandeur, nostalgia, and oftentimes, a sense of closure to a scene. This was Ronald Reagan’s final moment in the sun: a fitting end for an actor of the silver screen, as well as for the president who mastered televisual politics. In a culture so thoroughly saturated with the image, even the death of a minor celebrity is an occasion to replay film clips, interviews, paparazzi photos and the like. Moreover, these “flashpoints” grow in intensity and frequency as promotional culture, technological innovation, and the proliferation of new media outlets shape contemporary media culture. They are both cause and consequence of these moments of media excess. And, as Turner, Bonner and Marshall observe, “That is their point. It is their disproportionate nature that makes them so important: the scale of their visibility, their overwhelmingly excessive demonstration of the power of the relationship between mass-mediated celebrities and the consumers of popular culture” (3-4). B-Movie actor, corporate spokesman, state governor and, finally, US president, Ronald Reagan left an extraordinary photographic record. Small wonder, then, that Reagan’s death was a “flashpoint” of the highest order: an orgy of images, a media spectacle waiting to happen. After all, Reagan appeared in over 50 films during his career in Hollywood. Publicity stills and clips from Reagan’s film career, including Knute Rockne, All American, the biopic that earned Reagan his nickname “the Gipper”, King’s Row, and Bedtime for Bonzo provided a surreal, yet welcome respite from television’s obsessive (some might say morbidly so) live coverage of Reagan’s remains making their way across country. Likewise, archival footage of Reagan’s political career — most notably, images of the 1981 assassination attempt; his quip “not to make age an issue” during the 1984 presidential debate; and his 1987 speech at the Brandenburg Gate demanding that Soviet President Gorbachev, “tear down this wall” — provided the raw materials for press coverage that thoroughly dominated the global mediascape. None of which is to suggest, however, that the sheer volume of Reagan’s photographic record is sufficient to account for the endless replay and reinterpretation of Reagan’s life story. If we are to fully comprehend Reagan’s fame, we must acknowledge his seminal engagement with promotional culture, “a professional articulation between the news and entertainment media and the sources of publicity and promotion” (Turner, Bonner & Marshall 5) in advancing an extraordinary political career. Hitting His Mark In a televised address supporting Barry Goldwater’s nomination for the presidency delivered at the 1964 Republican Convention, Ronald Reagan firmly established his conservative credentials and, in so doing, launched one of the most remarkable and influential careers in American politics. Political scientist Gerard J. De Groot makes a compelling case that the strategy Reagan and his handlers developed in the 1966 California gubernatorial campaign would eventually win him the presidency. The centerpiece of this strategy was to depict the former actor as a political outsider. Crafting a persona he described as “citizen politician,” Reagan’s great appeal and enormous success lie in his uncanny ability to project an image founded on traditional American values of hard work, common sense and self-determination. Over the course of his political career, Reagan’s studied optimism and “no-nonsense” approach to public policy would resonate with an electorate weary of career politicians. Charming, persuasive, and seemingly “authentic,” Reagan ran gubernatorial and subsequent presidential campaigns that were distinctive in that they employed sophisticated public relations and marketing techniques heretofore unknown in the realm of electoral politics. The 1966 Reagan gubernatorial campaign took the then unprecedented step of employing an advertising firm, Los Angeles-based Spencer-Roberts, in shaping the candidate’s image. Leveraging their candidate’s ease before the camera, the Reagan team crafted a campaign founded upon a sophisticated grasp of the television industry, TV news routines, and the medium’s growing importance to electoral politics. For instance, in the days before the 1966 Republican primary, the Reagan team produced a five-minute film using images culled from his campaign appearances. Unlike his opponent, whose television spots were long-winded, amateurish and poorly scheduled pieces that interrupted popular programs, like Johnny Carson’s Tonight Show, Reagan’s short film aired in the early evening, between program segments (De Groot). Thus, while his opponent’s television spot alienated viewers, the Reagan team demonstrated a formidable appreciation not only for televisual style, but also, crucially, a sophisticated understanding of the nuances of television scheduling, audience preferences and viewing habits. Over the course of his political career, Reagan refined his media driven, media directed campaign strategy. An analysis of his 1980 presidential campaign reveals three dimensions of Reagan’s increasingly sophisticated media management strategy (Covington et al.). First, the Reagan campaign carefully controlled their candidate’s accessibility to the press. Reagan’s penchant for potentially damaging off-the-cuff remarks and factual errors led his advisors to limit journalists’ interactions with the candidate. Second, the character of Reagan’s public appearances, including photo opportunities and especially press conferences, grew more formal. Reagan’s interactions with the press corps were highly structured affairs designed to control which reporters were permitted to ask questions and to help the candidate anticipate questions and prepare responses in advance. Finally, the Reagan campaign sought to keep the candidate “on message.” That is to say, press releases, photo opportunities and campaign appearances focused on a single, consistent message. This approach, known as the Issue of the Day (IOD) media management strategy proved indispensable to advancing the administration’s goals and achieving its objectives. Not only was the IOD strategy remarkably effective in influencing press coverage of the Reagan White House, this coverage promoted an overwhelmingly positive image of the president. As the weeklong funeral amply demonstrated, Reagan was, and remains, one of the most popular presidents in modern American history. Reagan’s popular (and populist) appeal is instructive inasmuch as it illuminates the crucial distinction between “celebrity and its premodern antecedent, fame” observed by historian Charles L. Ponce de Leone (13). Whereas fame was traditionally bestowed upon those whose heroism and extraordinary achievements distinguished them from common people, celebrity is a defining feature of modernity, inasmuch as celebrity is “a direct outgrowth of developments that most of us regard as progressive: the spread of the market economy and the rise of democratic, individualistic values” (Ponce de Leone 14). On one hand, then, Reagan’s celebrity reflects his individualism, his resolute faith in the primacy of the market, and his defense of “traditional” (i.e. democratic) American values. On the other hand, by emphasizing his heroic, almost supernatural achievements, most notably his vanquishing of the “Evil Empire,” the Reagan mythology serves to lift him “far above the common rung of humanity” raising him to “the realm of the divine” (Ponce de Leone 14). Indeed, prior to his death, the Reagan faithful successfully lobbied Congress to create secular shrines to the standard bearer of American conservatism. For instance, in 1998, President Clinton signed a bill that officially rechristened one of the US capitol’s airports to Ronald Reagan Washington National Airport. More recently, conservatives working under the aegis of the Ronald Reagan Legacy Project have called for the creation of even more visible totems to the Reagan Revolution, including replacing Franklin D. Roosevelt’s profile on the dime with Reagan’s image and, more dramatically, inscribing Reagan in stone, alongside Washington, Jefferson, Lincoln and Teddy Roosevelt at Mount Rushmore (Gordon). Therefore, Reagan’s enduring fame rests not only on the considerable symbolic capital associated with his visual record, but also, increasingly, upon material manifestations of American political culture. The High Stakes of Media Politics What are we to make of Reagan’s fame and its implications for America? To begin with, we must acknowledge Reagan’s enduring influence on modern electoral politics. Clearly, Reagan’s “citizen politician” was a media construct — the masterful orchestration of ideological content across the institutional structures of news, public relations and marketing. While some may suggest that Reagan’s success was an anomaly, a historical aberration, a host of politicians, and not a few celebrities — Bill Clinton, George W. Bush, and Arnold Schwarzenegger among them — emulate Reagan’s style and employ the media management strategies he pioneered. Furthermore, we need to recognize that the Reagan mythology that is so thoroughly bound up in his approach to media/politics does more to obscure, rather than illuminate the historical record. For instance, in her (video taped) remarks at the funeral service, Margaret Thatcher made the extraordinary claim — a central tenet of the Reagan Revolution — that Ronnie won the cold war “without firing a shot.” Such claims went unchallenged, at least in the establishment press, despite Reagan’s well-documented penchant for waging costly and protracted proxy wars in Afghanistan, Africa, and Central America. Similarly, the Reagan hagiography failed to acknowledge the decisive role Gorbachev and his policies of “reform” and “openness” — Perestroika and Glasnost — played in the ending of the Cold War. Indeed, Reagan’s media managed populism flies in the face of what radical historian Howard Zinn might describe as a “people’s history” of the 1980s. That is to say, a broad cross-section of America — labor, racial and ethnic minorities, environmentalists and anti-nuclear activists among them — rallied in vehement opposition to Reagan’s foreign and domestic policies. And yet, throughout the weeklong funeral, the divisiveness of the Reagan era went largely unnoted. In the Reagan mythology, then, popular demonstrations against an unprecedented military build up, the administration’s failure to acknowledge, let alone intervene in the AIDS epidemic, and the growing disparity between rich and poor that marked his tenure in office were, to borrow a phrase, relegated to the dustbin of history. In light of the upcoming US presidential election, we ought to weigh how Reagan’s celebrity squares with the historical record; and, equally important, how his legacy both shapes and reflects the realities we confront today. Whether we consider economic and tax policy, social services, electoral politics, international relations or the domestic culture wars, Reagan’s policies and practices continue to determine the state of the union and inform the content and character of American political discourse. Increasingly, American electoral politics turns on the pithy soundbite, the carefully orchestrated pseudo-event, and a campaign team’s unwavering ability to stay on message. Nowhere is this more evident than in Ronald Reagan’s unmistakable influence upon the current (and illegitimate) occupant of the White House.

Introduction "Doesn't that wreck your records?" This is one of the first things I generally get asked when someone watches me at work in my home or while spinning at a party. It reminds me of a different but related question I once asked someone who worked at Rotate This!, a particularly popular Toronto DJ refuge, a few days after I had bought my first turntable: DJO: "How do you stop that popping and crackling sound your record gets when you scratch back and forth on the same spot for a while?" CLERK: "You buy two copies of everything, one you keep at home all wrapped-up nice and never use, and the other you mess with." My last $150 had just managed to pay for an old Dual direct drive record player. The precious few recently-released records I had were gifts. I nodded my head and made my way over to the rows of disks which I flipped through to make it look like I was maybe going to buy something. Lp cover after lp cover stared back at me all with names I had absolutely never heard of before, organised according to a hyper- hybridised classification scheme that completely escaped my dictionary-honed alphabetic expectations. Worst of all, there seemed to be only single copies of everything left! A sort of outsider's vertigo washed over me, and 3 minutes after walking into unfamiliar territory, I zipped back out onto the street. Thus was to begin my love/hate relationship with the source of all DJ sounds, surliness and misinformation--the independent record shop. My query had (without my planning) boldly pronounced my neophyte status. The response it solicited challenged my seriousness. How much was I willing to invest in order to ride "the wheels of steel"? Sequence 1 Will Straw describes the meteoric rise to prominence of the CD format, If the compact disk has emerged as one of the most dazzlingly effective of commodity forms, this has little to do with its technical superiority to the vinyl record (which we no longer remember to notice). Rather, the effectiveness has to do with its status as the perfect crossover consumer object. As a cutting-edge audiophile invention, it seduced the technophilic, connoisseurist males who typically buy new sound equipment and quickly build collections of recordings. At the same time, its visual refinement and high price rapidly rendered it legitimate as a gift. In this, the CD has found a wide audience among the population of casual record buyers.(61) Straw's point has to do with the fate of musical recordings within contemporary commodity culture. In the wake of a late 70's record industry slump, music labels turned their attention toward the recapturing of casual record sales (read: aging baby boomers). The general shape of this attempt revolved around a re-configuring of the record- shopping experience dedicated towards reducing "the intimidation seen as endemic to the environment of the record store."(59) The CD format, along with the development of super-sized, general interest (all-genre) record outlets has worked (according to Straw) to streamline record sales towards more-predictable patterns, all the while causing less "selection stress."(59) Re-issues and compilations, special-series trademarks, push-button listening stations, and maze-like display layouts, combined with department store-style service ("Can I help you find anything?") all work towards eliminating the need for familiarity with particular music "scenes" in order to make personally gratifying (and profit engendering) musical choices. Straw's analysis is exemplary in its dissatisfaction with treating the arena of personal musical choice as unaffected by any constraints apart from subjective matters of taste. Straw's evaluation also isolates the vinyl record as an object eminently ready (post-digital revolution) for subcultural appropriation. Its displacement by the CD as the dominant medium for collecting recorded music involved the recasting of the turntable as outdated and inferior, thereby relegating it to the dusty attic, basement or pawn shop (along with crates upon crates upon crates of records). These events set the stage for vinyl's spectacular rise from the ashes. The most prominent feature of this re-emergence has to do not simply with possession of the right kind of stuff (the cachet of having a music collection difficult for others to borrow aside), but with what vinyl and turntable technology can do. Bridge In Subculture: The Meaning of Style, Dick Hebdige claims that subcultures are, cultures of conspicuous consumption...and it is through the distinctive rituals of consumption, through style, that the subculture at once reveals its "secret identity" and communicates its forbidden meanings. It is basically the way in which commodities are used in subculture which mark the subculture off from more orthodox cultural formations.(103 Hebdige borrows the notion of bricolage from Levi Strauss in order to describe the particular kind of use subcultures make of the commodities they appropriate. Relationships of identity, difference and order are developed from out of the minds of those who make use of the objects in question and are not necessarily determined by particular qualities inherent to the objects themselves. Henceforth a safety pin more often used for purposes like replacing missing buttons or temporarily joining pieces of fabric can become a punk fashion statement once placed through the nose, ear or torn Sex Pistols tee-shirt. In the case of DJ culture, it is the practice of mixing which most obviously presents itself as definitive of subcultural participation. The objects of conspicuous consumption in this case--record tracks. If mixing can be understood as bricolage, then attempts "to discern the hidden messages inscribed in code"(18) by such a practice are not in vain. Granting mixing the power of meaning sets a formidable (semiotic) framework in place for investigating the practice's outwardly visible (spectacular) form and structure. Hebdige's description of bricolage as a particularly conspicuous and codified type of using, however, runs the risk of privileging an account of record collecting and mixing which interprets it entirely on the model of subjective expression.(1.) What is necessary is a means of access to the dialogue which takes place between a DJ and her records as such. The contents of a DJ's record bag (like Straw's CD shopping bag) are influenced by more that just her imagination, pocket book and exposure to different kinds of music. They are also determined in an important way by each other. Audio mixing is not one practice, it is many, and the choice to develop or use one sort of skill over another is intimately tied up with the type and nature of track one is working with. Sequence 2 The raw practice of DJing relies heavily on a slider integral to DJ mixers known as the _cross-fader_(ital). With the standard DJ set up, when the cross-fader is all the way to the left, the left turntable track plays through the system; vice versa when the fader is all the way to the right. In between is the "open" position which allows both inputs to be heard simultaneously. The most straightforward mixing technique, "cutting," involves using this toggle to quickly switch from one source to another--resulting in the abrupt end of one sound- flow followed by its instantaneous replacement. This technique can be used to achieve a variety of different effects--from the rather straightforward stringing together of the final beat of a four bar sequence from one track with a strong downbeat from something new in order to provide continuous, but sequential musical output, to the thoroughly difficult practice of "beat juggling," where short excerpts of otherwise self-contained tracks ("breaks") are isolated and then extended indefinitely through the use of two copies of the same record (while one record plays, the DJ spins the other back to the downbeat of the break in question, which is then released in rhythm). In both cases timing and rhythm are key. These features of the practice help to explain DJ predilections for tracks which make heavy, predictable use of their rhythm sections. "Blending" is a second technique which uses the open position on the cross-fader to mix two inputs into a live sonic collage. Tempo, rhythm and "density" of source material have an enormous impact on the end result. While any two tracks can be layered in this way, beats that are not synchronized are quick to create cacophony, and vocals also tend to clash dramatically. Melodic lines in general pose certain challenges here since these are in particular keys and have obvious starts and finishes. This is one reason why tracks produced specifically for DJing often have such long, minimal intros and exits. This makes it much easier to create "natural" sounding blends. Atmospheric sounds, low-frequency hums, speech samples and repetitive loops with indeterminate rhythm structures are often used for these segments in order to allow drawn-out, subtle transitions when moving between tracks. If an intro contains a fixed beat (as is the case often with genres constructed specifically for non-stop dancing like house, techno and to some extent drum and bass), then those who want seamless blends need to "beat match" if they want to maintain a dancer's groove. The roots of this technique go back to disco and demand fairly strict genre loyalty in order to insure that a set's worth of tracks all hover around the same tempo, defined in beats-per- minute, or BPMs. The basic procedure involves finding the downbeat of the track one wishes to mix through a set of headphones, releasing that beat in time with the other record while making fine tempo- adjustments via the turntable's pitch control to the point where the track coming through the earphones and the track being played over the system are in synch. The next step is "back-spinning" or "needle dropping" to the start of the track to be mixed, then releasing it again, this time with the cross-fader open. Volume levels can then be adjusted in order to allow the new track to slowly take prominence (the initial track being close to its end at this point) before the cross-fader is closed into the new position and the entire procedure is repeated. Scratching is perhaps the most notorious mixing technique and involves the most different types of manipulations. The practice is most highly developed in hip hop (and related genres like drum and bass) and is used both as an advanced cutting technique for moving between tracks as well as a sonic end-in-itself. It's genesis is attributed to a South Bronx DJ known as Grand Wizard Theodore who was the first (1977) to try to make creative use of the sound associated with moving a record needle back and forth over the same drumbeat, a phenomena familiar to DJs used to cueing-up downbeats through headphones. This trick is now referred to as the "baby scratch," and it along with an ever-increasing host of mutations and hybrids make- up the skills that pay the bills for hip hop DJs. In the case of many of these techniques, the cross-fader is once again used heavily in order to remove unwanted elements of particular scratches from the mix, as well as adding certain staccato and volume-fading effects. Isolated, "pure" sounds are easiest to scratch with and are therefore highly sought after by this sort of DJ--a pastime affectionately referred to as "digging in the crates." Sources of such sounds are extremely diverse, but inevitably revolve around genre's which use minimal orchestration (like movie-soundtracks), accentuated rhythms with frequent breakdowns (like funk or jazz), or which eschew musical form all together (like sound-effects, comedy and children's records). Exit To answer the question which started this investigation, in the end, how wrecked my records get depends a lot on what I'm using them for. To be sure, super-fast scratching patterns and tricks that use lots of back-spinning like beat-juggling will eventually "burn" static into spots on one's records. But with used records costing as little as $1 for three, and battle records (2.) widely available, the effect of this feature of the technology on the actual pursuit of the practice is negligible. And most techniques don't noticeably burn records at all, especially if a DJ's touch is light enough to allow for minimal tone-arm weight (a parameter which controls a turntable's groove-tracking ability). This is the kind of knowledge which comes from interaction with objects. It is also the source of a great part of the subcultural bricoleur's stylistic savvy. Herein lies the essence of the intimidating power of the indie record shop--its display of intimate, physical familiarity with the hidden particularities of the new vinyl experience. Investigators confronted with such familiarity need to find ways to go beyond analyses which stop at the level of acknowledgment of the visible logic displayed by spectacular subcultural practices if they wish to develop nuanced accounts of subcultural life. Such plumbing of the depths often requires listening in the place of observing--whether to first-hand accounts collected through ethnography or to the subtle voice of the objects themselves. (1.) An example of such an account: "DJ-ing is evangelism; a desire to share songs. A key skill is obviously not just to drop the popular, well-known songs at the right part of the night, but to pick the right new releases, track down the obscurer tunes and newest imports, get hold of next month's big tune this month; you gather this pile, this tinder, together, then you work the records, mix them, drop them, cut them, scratch them, melt them, beat them all together until they unite. Voilà; disco inferno." Dave Haslam, "DJ Culture," p. 169. (2.) Records specifically designed by and for scratch DJs and which consist of long strings of scratchable sounds. References Haslam, David.

Web services composition is emerging as a promising technology for the effective automation of application-to-application collaborations. The application integration problems have been subject of much research in the past years. However, with growth in importance of business process automation and highly dynamic nature of the Internet, this research has taken on a new significance and importance. Adequate solutions to this problem will be very important to make enterprise systems more flexible, robust and usable in the future. In this dissertation, we present a novel approach for the declarative definition and scalable orchestration of composite Web services in large, autonomous, heterogeneous, and dynamic environments. We first propose a composition model for composing Web services in a personalized and adaptive manner. We model composite Web services based on statecharts. To cater for large amounts of dynamic Web services, we use the concept of service community that groups services together and is responsible for the runtime selection of services against user's preferences. We use the concept of process schema that specific users can adjust with their personal preferences. A set of exception handling policies can be specified to proactively react to runtime exceptions. We then propose a tuple space based service orchestration model for distributed, self-managed composite services execution. We introduce the concept of execution controller that is associated with a service and is responsible for monitoring and controlling service executions. The knowledge required by a controller is statically extracted from the specification of personalized composite services. We also present techniques for robust Web services provisioning. The techniques presented in this dissertation are implemented in Self-Serv, a prototype that provides a set of tools for Web service composition and execution. Finally, we conduct an extensive usability and performance study of the proposed techniques. The experimental results reveal that our system i) provides an efficient support for specifying, deploying, and accessing composite services; ii) is more scalable and outperforms the centralized approach when the exchanged messages become bigger; and iii) is more robust and adaptive in highly dynamic environments.

In 1947 Ives finally managed to bring out a much-revised second edition of the Concord Sonata, and the changes reveal much about his compositional process and ability to self-criticize. Contrary to what has been asserted by Elliott Carter and others, Ives was not merely trying to modernize the piece, but to improve its notation and in many cases to add back in some of the complexity that had been too timidly omitted from the first edition. Some 42 recordings of the Concord are summarily discussed (it may be the most widely recorded modern piano work), along with Henry Brant’s orchestration of the piece, A Concord Symphony.
