In turbomachinery applications blade fouling represents a main cause of performance degradation. Among the different techniques currently available, online water washing is one of the most effective in removing deposit from the blades. Since this kind of washing is applied when the machine is close to design conditions, injected droplets are strongly accelerated when they reach the rotor blades and the understanding of their interaction with the blades is not straightforward. Moreover, undesirable phenomena like blades erosion or liquid film formation can occur. The present study aims at assessing droplets dragging from the injection system placed at the compressor inlet till the first stage rotor blades, with a focus on droplets impact locations, on the washing process and the associated risk of erosion. 3D numerical simulations of the whole compressor geometry (up to the first rotor stage) are performed by using Ansys Fluent to account for the asymmetric distribution of the sprays around of the machine struts, IGV and rotor blades. The simulations are carried out by adopting the k-ε realizable turbulence model with standard wall functions, coupled with the discretephase model to track injected droplets motion. Droplets-wall interaction is also accounted for by adopting the Stanton-Rutland model which define a droplet impact outcome depending on the impact conditions. The induced erosion is evaluated by adopting an erosion model previously developed by some of the authors and implemented in Fluent through the use of a User Defined Function (UDF). Two sets of simulations are performed, by considering the rotor still and rotating, representative of off-line and on-line water washing conditions, respectively. In the rotating simulation, the Multiple Reference Frame Model is used. The obtained results demonstrate that the washing process differs substantially between the fixed and the rotating case. Moreover, to quantify the water washing effectiveness and the erosion risk, new indices were introduced and computed for the main components of the machine. These indices can be considered as useful prescriptions in the optimization process of water washing systems.

Common exposure to various kinds of mobile and stationary devices based on screen technologies produce substantiation for the term screen communications. The relevancy of its usage is specified, also the principles of functioning in context of updating social practices and multimedia informational space are substantiated in the article. The issue is due to the fact that the term screen communications has not yet been put into academic usage, unlike such terms as communication, mass communication and social communication. Nevertheless contemporary social practices for using the screen (cell phone, e-book, tablet, etc.) have turned into a daily routine and even demonstrate screen-phobia. The evolution of the technologies, new media (multimedia, multi-platforms), growth of information flows, form and content diversity of informational products, socialization effect and accumulation of empirical experience urge society to resort to the screen for receiving information (film-, video-, TV-production, Internet sites, social networks, computers, cell phones, tablets, e-books, electronic billboards, videoinformational systems, etc.). The article analyzes characteristics of well-known communications forms and types when superimposed to the term screen communications. The problem raised a need for thorough analysis of screen communications which different strata of society master; moreover, a great significance of studying peculiarities of screen culture in the digital era is emphasized. The article cites information about the emergence of Generation C, formed by social networks (a lecture on Nielsen Consumer 360 Conference). The Connected Collective Consumer has a distinguished identity and is ready for self-expression (ideas, cultural projects, etc.) within the group. As a conclusion it substantiates the nonlinearity of the social systems development, including social networks which are exposed to both the socialization effect and diversification and disintegration processes, which leads to a communication connections collapse.

Many of the world’s productive Jurassic reservoirs are intensively bioturbated, including the sediments of the Upper Jurassic Hanifa Formation. Hydrocarbon exploration and production from such reservoirs require a reliable prediction of petrophysical properties (i.e., porosity, permeability, acoustic velocity) by linking and assessment of ichnofabrics and trace fossils and determining their impact on reservoir quality. In this study, we utilized outcrop carbonate samples from the Hanifa Formation to understand the main controlling factors on reservoir quality (porosity and permeability) and acoustic velocity of bioturbated carbonates, by using thin-section petrography, SEM, XRD, CT scan, porosity, permeability, and acoustic velocity measurement. The studied samples are dominated by Thalassinoides burrows that have burrow intensity ranging from ~4% to 27%, with porosity and permeability values ranging from ~1% to 20%, and from 0.002 mD up to 1.9 mD, respectively. Samples with coarse grain-filled burrows have higher porosity (average µ = 14.44% ± 3.25%) and permeability (µ = 0.56 mD ± 0.55) than samples with fine grain-filled burrows (µ = 6.56% ± 3.96%, and 0.07 mD ± 0.16 mD). The acoustic velocity is controlled by an interplay of porosity, bioturbation, and mineralogy. Samples with relatively high porosity and permeability values (>10% and >0.1 mD) have lower velocities (<5 km/s) compared to tight samples with low porosities and permeabilities (<10% and <0.1 mD). The mineralogy of the analyzed samples is dominated by calcite (~94% of total samples) with some quartz content (~6% of total samples). Samples characterized with higher quartz (>10% quartz content) show lower velocities compared to the samples with lower quartz content. Bioturbation intensity, alone, has no control on velocity, but when combined with burrow fill, it can be easier to discriminate between high and low velocity samples. Fine grain-filled burrows have generally lower porosity and higher velocities (µ = 5.46 km/s) compared to coarse grain-filled burrows (µ = 4.52 km/s). Understanding the main controlling factor on petrophysical properties and acoustic velocity of bioturbated strata can enhance our competency in reservoir quality prediction and modeling for these bioturbated units.

Abstract Ever since its introduction over five decades ago, geometric solid modeling has been crucial for engineering design purposes and is used in engineering software packages such as computer-aided design (cad), computer-aided manufacturing, computer-aided engineering, etc. Solid models produced by cad software have been used to transfer geometric information from designers to manufacturers. Since the emergence of additive manufacturing (AM), a CAD file can also be directly uploaded to a three-dimensional (3D) printer and used for production. AM techniques allow manufacturing of complex geometric objects such as bio-inspired structures and lattice structures. These structures are shapes inspired by nature and periodical geometric shapes consisting of struts interconnecting in nodes. Both structures have unique properties such as significantly reduced weight. However, geometric modeling of such structures has significant challenges due to the inability of current techniques to handle their geometric complexity. This calls for a novel modeling method that would allow engineers to design complex geometric objects. This survey paper reviews geometric modeling methods of complex structures to support bio-inspired design created for AM which includes discussing reasoning behind bio-inspired design, limitations of current modeling approaches applied to bio-inspired structures, challenges encountered with geometric modeling, and opportunities that these challenges reveal. Based on the review, a need for a novel geometric modeling method for bio-inspired geometries produced by AM is identified. A framework for such a bio-inspired geometric modeling method is proposed as a part of this work.

Accurately predicting the 3D in-situ stress filed is critical in coal mining. We proposed a workflow that is based on 3D seismic attributes to predict the in-situ stress field of a coal mine located in Shijiazhuang, Shanxi, China. First, we interpreted the faults and folds within our study area. Then, we determine the directions and types of in-situ stress by analyzing the interpreted faults and folds. Under the assumption that the process of strata deformation can be simulated by a thin-plate theory, we deduce the equations to compute in-situ stress as a function of seismic curvature attribute and elastic parameters inverted from seismic data. We also proposed a stability factor that is based computed stress filed. The results show that the in-situ stress field within our study area is dominated by the compression stress along the Northwest–Southeast direction. Based on the proposed stability coefficient, we further predicted the zones that have abnormal rock mass stability.

Abstract Background Additive manufacturing (AM), commonly called 3D Printing (3DP), for medical devices is growing in popularity due to the technology’s ability to create complex geometries and patient-matched products. However, due to the process variabilities which can exist between 3DP systems, manufacturer workflows, and digital conversions, there may be variabilities among 3DP parts or between design files and final manufactured products. The overall goal of this project is to determine the dimensional variability of commercially obtained 3DP titanium lattice-containing test coupons and compare it to the original design files. Methods This manuscript outlines the procedure used to measure dimensional variability of 3D Printed lattice coupons and analyze the differences in external dimensions and pore area when using laser and electron beam fabricated samples. The key dimensions measured were the bulk length, width, and depth using calipers. Strut thickness and pore area were assessed for the lattice components using optical imaging and µCT. Results Results show a difference in dimensional measurement between printed parts and the computer-designed files for all groups analyzed including the internal lattice dimensions. Measurements of laser manufactured coupons varied from the nominal by less than 0.2 mm and results show averages greater than the nominal value for length, width, and depth dimensions. Measurements of Electron Beam Melting coupons varied between 0.4 mm-0.7 mm from the nominal value and showed average lengths below the nominal dimension while the width and depths were greater than the nominal values. The length dimensions of Laser Powder Bed Fusion samples appeared to be impacted by hot isostatic press more than the width and depth dimension. When lattice relative density was varied, there appeared to be little impact on the external dimensional variability for the as-printed state. Conclusions Based on these results, we can conclude that there are relevant variations between designed files and printed parts. However, we cannot currently state if these results are clinically relevant and further testing needs to be conducted to apply these results to real-world situations.

Background: Access to oral care is a real public health challenge because dental pathologies affect all social strata, even the most disadvantaged. Knowing that the peripheral level in the health pyramid of Cameroon does not always benefit from oral services, this work proposed to present the offer of oral services in conventional medicine and traditional medicine in the Health District of Mbanga.
 Materials and methods: A mixed descriptive cross-sectional study was carried out in the Mbanga health district taking place from April 2021 to January 2022. All dentists and traditional therapists providing oral care were included in the study and having given their consent. To do this, a reading grid and an interview guide made it possible to obtain two types of variables. The qualitative variables were analyzed manually with the color code. While the quantitative variables were analyzed using SPSS version 26.0 software.
 Results: Total 13 traditional healers were found and two dental surgeons working in the community of Mbanga were interacted for this study. The dentists were only women with less than a year of experience. The technical platform consisted of a portable dental chair and a dental case. The benefits were essentially curative. The traditional therapists worked in counters or in their vehicles. The majority of the products were decoctions. They treated oral ailments and would refer to the hospital in case of complications. Only a few used products to perform dental extractions.
 Conclusion: The offer of services must be within the reach of every individual. However, this offer must be in line with the need.

'He did what the cipher could not, he rescued himself.' -- Alfred Bester, The Stars My Destination (23) On many levels, the new Nine Inch Nails album The Fragile is a gritty meditation about different types of End: the eternal relationship cycle of 'fragility, tension, ordeal, fragmentation' (adapted, with apologies to Wilhelm Reich); fin-de-siècle anxiety; post-millennium foreboding; a spectre of the alien discontinuity that heralds an on-rushing future vastly different from the one envisaged by Enlightenment Project architects. In retrospect, it's easy for this perspective to be dismissed as jargon-filled cyber-crit hyperbole. Cyber-crit has always been at its best too when it invents pre-histories and finds hidden connections between different phenomena (like the work of Greil Marcus and early Mark Dery), and not when it is closer to Chinese Water Torture, name-checking the canon's icons (the 'Deleuze/Guattari' tag-team), texts and key terms. "The organization of sound is interpreted historically, politically, socially ... . It subdues music's ambition, reins it in, restores it to its proper place, reconciles it to its naturally belated fate", comments imagineer Kodwo Eshun (4) on how cyber-crit destroys albums and the innocence of the listening experience. This is how official histories are constructed a priori and freeze-dried according to personal tastes and prior memes: sometimes the most interesting experiments are Darwinian dead-ends that fail to make the canon, or don't register on the radar. Anyone approaching The Fragile must also contend with the music industry's harsh realities. For every 10 000 Goth fans who moshed to the primal 'kill-fuck-dance' rhythms of the hit single "Closer" (heeding its siren-call to fulfil basic physiological needs and build niche-space), maybe 20 noted that the same riff returned with a darker edge in the title track to The Downward Spiral, undermining the glorification of Indulgent hedonism. "The problem with such alternative audiences," notes Disinformation Creative Director Richard Metzger, "is that they are trying to be different -- just like everyone else." According to author Don Webb, "some mature Chaos and Black Magicians reject their earlier Nine Inch Nails-inspired Goth beginnings and are extremely critical towards new adopters because they are uncomfortable with the subculture's growing popularity, which threatens to taint their meticulously constructed 'mysterious' worlds. But by doing so, they are also rejecting their symbolic imprinting and some powerful Keys to unlocking their personal history." It is also difficult to separate Nine Inch Nails from the commercialisation and colossal money-making machine that inevitably ensued on the MTV tour circuit: do we blame Michael Trent Reznor because most of his audience are unlikely to be familiar with 'first-wave' industrial bands including Cabaret Voltaire and the experiments of Genesis P. Orridge in Throbbing Gristle? Do we accuse Reznor of being a plagiarist just because he wears some of his influences -- Dr. Dre, Daft Punk, Atari Teenage Riot, Pink Floyd's The Wall (1979), Tom Waits's Bone Machine (1992), David Bowie's Low (1977) -- on his sleeve? And do we accept no-brain rock critic album reviews who quote lines like 'All the pieces didn't fit/Though I really didn't give a shit' ("Where Is Everybody?") or 'And when I suck you off/Not a drop will go to waste' ("Starfuckers Inc") as representative of his true personality? Reznor evidently has his own thoughts on this subject, but we should let the music speak for itself. The album's epic production and technical complexity turned into a post-modern studio Vision Quest, assisted by producer Alan Moulder, eleventh-hour saviour Bob Ezrin (brought in by Reznor to 'block-out' conceptual and sonic continuity), and a group of assault-technicians. The fruit of these collaborations is an album where Reznor is playing with our organism's time-binding sense, modulating strange emotions through deeply embedded tonal angularities. During his five-year absence, Trent Reznor fought diverse forms of repetitious trauma, from endogenous depression caused by endless touring to the death of his beloved grandmother (who raised him throughout childhood). An end signals a new beginning, a spiral is an open-ended and ever-shifting structure, and so Reznor sought to re-discover the Elder Gods within, a shamanic approach to renewal and secular salvation utilised most effectively by music PR luminary and scientist Howard Bloom. Concerned with healing the human animal through Ordeals that hard-wire the physiological baselines of Love, Hate and Fear, Reznor also focusses on what happens when 'meaning-making' collapses and hope for the future cannot easily be found. He accurately captures the confusion that such dissolution of meaning and decline of social institutions brings to the world -- Francis Fukuyama calls this bifurcation 'The Great Disruption'. For a generation who experienced their late childhood and early adolescence in Reagan's America, Reznor and his influences (Marilyn Manson and Filter) capture the Dark Side of recent history, unleashed at Altamont and mutating into the Apocalyptic style of American politics (evident in the 'Star Wars'/SDI fascination). The personal 'psychotic core' that was crystallised by the collapse of the nuclear family unit and supportive social institutions has returned to haunt us with dystopian fantasies that are played out across Internet streaming media and visceral MTV film-clips. That such cathartic releases are useful -- and even necessary (to those whose lives have been formed by socio-economic 'life conditions') is a point that escapes critics like Roger Scruton, some Christian Evangelists and the New Right. The 'escapist' quality of early 1980s 'Rapture' and 'Cosmocide' (Hal Lindsey) prophecies has yielded strange fruit for the Children of Ezekiel, whom Reznor and Marilyn Manson are unofficial spokes-persons for. From a macro perspective, Reznor's post-human evolutionary nexus lies, like J.G. Ballard's tales, in a mythical near-future built upon past memory-shards. It is the kind of worldview that fuses organic and morphogenetic structures with industrial machines run amok, thus The Fragile is an artefact that captures the subjective contents of the different mind produced by different times. Sonic events are in-synch but out of phase. Samples subtly trigger and then scramble kinaesthetic-visceral and kinaesthetic-tactile memories, suggestive of dissociated affective states or body memories that are incapable of being retrieved (van der Kolk 294). Perhaps this is why after a Century of Identity Confusion some fans find it impossible to listen to a 102-minute album in one sitting. No wonder then that the double album is divided into 'left' and 'right' discs (a reference to split-brain research?). The real-time track-by-track interpretation below is necessarily subjective, and is intended to serve as a provisional listener's guide to the aural ur-text of 1999. The Fragile is full of encrypted tones and garbled frequencies that capture a world where the future is always bleeding into a non-recoverable past. Turbulent wave-forms fight for the listener's attention with prolonged static lulls. This does not make for comfortable or even 'nice' listening. The music's mind is a snapshot, a critical indicator, of the deep structures brewing within the Weltanschauung that could erupt at any moment. "Somewhat Damaged" opens the album's 'Left' disc with an oscillating acoustic strum that anchor's the listener's attention. Offset by pulsing beats and mallet percussion, Reznor builds up sound layers that contrast with lyrical epitaphs like 'Everything that swore it wouldn't change is different now'. Icarus iconography is invoked, but perhaps a more fitting mythopoeic symbol of the journey that lies ahead would be Nietzsche's pursuit of his Ariadne through the labyrinth of life, during which the hero is steadily consumed by his numbing psychosis. Reznor fittingly comments: 'Didn't quite/Fell Apart/Where were you?' If we consider that Reznor has been repeating the same cycle with different variations throughout all of his music to date, retro-fitting each new album into a seamless tapestry, then this track signals that he has begun to finally climb out of self-imposed exile in the Underworld. "The Day the World Went Away" has a tremendously eerie opening, with plucked mandolin effects entering at 0:40. The main slashing guitar riff was interpreted by some critics as Reznor's attempt to parody himself. For some reason, the eerie backdrop and fragmented acoustic guitar strums recalls to my mind civil defence nuclear war films. Reznor, like William S. Burroughs, has some powerful obsessions. The track builds up in intensity, with a 'Chorus of the Damned' singing 'na na nah' over apocalyptic end-times imagery. At 4:22 the track ends with an echo that loops and repeats. "The Frail" signals a shift to mournful introspectiveness with piano: a soundtrack to faded 8 mm films and dying memories. The piano builds up slowly with background echo, holds and segues into ... "The Wretched", beginning with a savage downbeat that recalls earlier material from Pretty Hate Machine. 'The Far Aways/Forget It' intones Reznor -- it's becoming clear that despite some claims to the contrary, there is redemption in this album, but it is one borne out of a relentless move forward, a strive-drive. 'You're finally free/You could be' suggest Reznor studied Existentialism during his psychotherapy visits. This song contains perhaps the ultimate post-relationship line: 'It didn't turn out the way you wanted it to, did it?' It's over, just not the way you wanted; you can always leave the partner you're with, but the ones you have already left will always stain your memories. The lines 'Back at the beginning/Sinking/Spinning' recall the claustrophobic trapped world and 'eternal Now' dislocation of Post-Traumatic Stress Disorder victims. At 3:44 a plucked cello riff, filtered, segues into a sludge buzz-saw guitar solo. At 5:18 the cello riff loops and repeats. "We're in This Together Now" uses static as percussion, highlighting the influence of electricity flows instead of traditional rock instrument configurations. At 0:34 vocals enter, at 1:15 Reznor wails 'I'm impossible', showing he is the heir to Roger Waters's self-reflective rock-star angst. 'Until the very end of me, until the very end of you' reverts the traditional marriage vow, whilst 'You're the Queen and I'm the King' quotes David Bowie's "Heroes". Unlike earlier tracks like "Reptile", this track is far more positive about relationships, which have previously resembled toxic-dyads. Reznor signals a delta surge (breaking through barriers at any cost), despite a time-line morphing between present-past-future. At 5:30 synths and piano signal a shift, at 5:49 the outgoing piano riff begins. The film-clip is filled with redemptive water imagery. The soundtrack gradually gets more murky and at 7:05 a subterranean note signals closure. "The Fragile" is even more hopeful and life-affirming (some may even interpret it as devotional), but this love -- representative of the End-Times, alludes to the 'Glamour of Evil' (Nico) in the line 'Fragile/She doesn't see her beauty'. The fusion of synths and atonal guitars beginning at 2:13 summons forth film-clip imagery -- mazes, pageants, bald eagles, found sounds, cloaked figures, ruined statues, enveloping darkness. "Just like You Imagined" opens with Soundscapes worthy of Robert Fripp, doubled by piano and guitar at 0:39. Drums and muffled voices enter at 0:54 -- are we seeing a pattern to Reznor's writing here? Sonic debris guitar enters at 1:08, bringing forth intensities from white noise. This track is full of subtle joys like the 1:23-1:36 solo by David Bowie pianist Mike Garson and guitarist Adrian Belew's outgoing guitar solo at 2:43, shifting back to the underlying soundscapes at 3:07. The sounds are always on the dissipative edge of chaos. "Just like You Imagined" opens with Soundscapes worthy of Robert Fripp, doubled by piano and guitar at 0:39. Drums and muffled voices enter at 0:54 -- are we seeing a pattern to Reznor's writing here? Sonic debris guitar enters at 1:08, bringing forth intensities from white noise. This track is full of subtle joys like the 1:23-1:36 solo by David Bowie pianist Mike Garson and guitarist Adrian Belew's outgoing guitar solo at 2:43, shifting back to the underlying soundscapes at 3:07. The sounds are always on the dissipative edge of chaos. "Pilgrimage" utilises a persistent ostinato and beat, with a driving guitar overlay at 0:18. This is perhaps the most familiar track, using Reznor motifs like the doubling of the riff with acoustic guitars between 1:12-1:20, march cries, and pitch-shift effects on a 3:18 drumbeat/cymbal. Or at least I could claim it was familiar, if it were not that legendary hip-hop producer and 'edge-of-panic' tactilist Dr. Dre helped assemble the final track mix. "No, You Don't" has been interpreted as an attack on Marilyn Manson and Hole's Courntey Love, particularly the 0:47 line 'Got to keep it all on the outside/Because everything is dead on the inside' and the 2:33 final verse 'Just so you know, I did not believe you could sink so low'. The song's structure is familiar: a basic beat at 0:16, guitars building from 0:31 to sneering vocals, a 2:03 counter-riff that merges at 2:19 with vocals and ascending to the final verse and 3:26 final distortion... "La Mer" is the first major surprise, a beautiful and sweeping fusion of piano, keyboard and cello, reminiscent of Symbolist composer Debussy. At 1:07 Denise Milfort whispers, setting the stage for sometime Ministry drummer Bill Reiflin's jazz drumming at 1:22, and a funky 1:32 guitar/bass line. The pulsing synth guitar at 2:04 serves as anchoring percussion for a cinematic electronica mindscape, filtered through new layers of sonic chiaroscuro at 2:51. 3:06 phase shifting, 3:22 layer doubling, 3:37 outgoing solo, 3:50-3:54 more swirling vocal fragments, seguing into a fading cello quartet as shadows creep. David Carson's moody film-clip captures the end more ominously, depicting the beauty of drowning. This track contains the line 'Nothing can stop me now', which appears to be Reznor's personal mantra. This track rivals 'Hurt' and 'A Warm Place' from The Downward Spiral and 'Something I Can Never Have' from Pretty Hate Machine as perhaps the most emotionally revealing and delicate material that Reznor has written. "The Great Below" ends the first disc with more multi-layered textures fusing nostalgia and reverie: a twelve-second cello riff is counter-pointed by a plucked overlay, which builds to a 0:43 washed pulse effect, transformed by six second pulses between 1:04-1:19 and a further effects layer at 1:24. E-bow effects underscore lyrics like 'Currents have their say' (2:33) and 'Washes me away' (2:44), which a 3:33 sitar riff answers. These complexities are further transmuted by seemingly random events -- a 4:06 doubling of the sitar riff which 'glitches' and a 4:32 backbeat echo that drifts for four bars. While Reznor's lyrics suggest that he is unable to control subjective time-states (like The Joker in the Batman: Dark Knight series of Kali-yuga comic-books), the track constructions show that the Key to his hold over the listener is very carefully constructed songs whose spaces resemble Pythagorean mathematical formulas. Misdirecting the audience is the secret of many magicians. "The Way Out Is Through" opens the 'Right' disc with an industrial riff that builds at 0:19 to click-track and rhythm, the equivalent of a weaving spiral. Whispering 'All I've undergone/I will keep on' at 1:24, Reznor is backed at 1:38 by synths and drums coalescing into guitars, which take shape at 1:46 and turn into a torrential electrical current. The models are clearly natural morphogenetic structures. The track twists through inner storms and torments from 2:42 to 2:48, mirrored by vocal shards at 2:59 and soundscapes at 3:45, before piano fades in and out at 4:12. The title references peri-natal theories of development (particularly those of Stanislav Grof), which is the source of much of the album's imagery. "Into the Void" is not the Black Sabbath song of the same name, but a catchy track that uses the same unfolding formula (opening static, cello at 0:18, guitars at 0:31, drums and backbeat at 1:02, trademark industrial vocals and synth at 1:02, verse at 1:23), and would not appear out of place in a Survival Research Laboratories exhibition. At 3:42 Reznor plays with the edge of synth soundscapes, merging vocals at 4:02 and ending the track nicely at 4:44 alone. "Where Is Everybody?" emulates earlier structures, but relies from 2:01 on whirring effects and organic rhythms, including a flurry of eight beat pulses between 2:40-2:46 and a 3:33 spiralling guitar solo. The 4:26 guitar solo is pure Adrian Belew, and is suddenly ended by spluttering static and white noise at 5:13. "The Mark Has Been Made" signals another downshift into introspectiveness with 0:32 ghostly synth shimmers, echoed by cello at 1:04 which is the doubled at 1:55 by guitar. At 2:08 industrial riffs suddenly build up, weaving between 3:28 distorted guitars and the return of the repressed original layer at 4:16. The surprise is a mystery 32 second soundscape at the end with Reznor crooning 'I'm getting closer, all the time' like a zombie devil Elvis. "Please" highlights spacious noise at 0:48, and signals a central album motif at 1:04 with the line 'Time starts slowing down/Sink until I drown'. The psychic mood of the album shifts with the discovery of Imagination as a liberating force against oppression. The synth sound again is remarkably organic for an industrial album. "Starfuckers Inc" is the now infamous sneering attack on rock-stardom, perhaps at Marilyn Manson (at 3:08 Reznor quotes Carly Simon's 'You're So Vain'). Jungle beats and pulsing synths open the track, which features the sound-sculpting talent of Pop Will Eat Itself member Clint Mansell. Beginning at 0:26, Reznor's vocals appear to have been sampled, looped and cut up (apologies to Brion Gysin and William S. Burroughs). The lines 'I have arrived and this time you should believe the hype/I listened to everyone now I know everyone was right' is a very savage and funny exposure of Manson's constant references to Friedrich Nietzsche's Herd-mentality: the Herd needs a bogey-man to whip it into submission, and Manson comes dangerous close to fulfilling this potential, thus becoming trapped by a 'Stacked Deck' paradox. The 4:08 lyric line 'Now I belong I'm one of the Chosen Ones/Now I belong I'm one of the Beautiful Ones' highlights the problem of being Elect and becoming intertwined with institutionalised group-think. The album version ditches the closing sample of Gene Simmons screaming "Thankyou and goodnight!" to an enraptured audience on the single from KISS Alive (1975), which was appropriately over-the-top (the alternate quiet version is worth hearing also). "The danger Marilyn Manson faces", notes Don Webb (current High Priest of the Temple of Set), "is that he may end up in twenty years time on the 'Tonight Show' safely singing our favourite songs like a Goth Frank Sinatra, and will have gradually lost his antinomian power. It's much harder to maintain the enigmatic aura of an Evil villain than it is to play the clown with society". Reznor's superior musicianship and sense of irony should keep him from falling into the same trap. "Complication" juggernauts in at 0:57 with screaming vocals and a barrage of white noise at 1:56. It's clear by now that Reznor has read his psychological operations (PSYOP) manuals pertaining to blasting the hell out of his audiences' psyche by any means necessary. Computer blip noise and black light flotation tank memories. Dislocating pauses and time-bends. The aural equivalent of Klein bottles.

Computer blip noise and black light flotation tank memories. Dislocating pauses and time-bends. The aural equivalent of Klein bottles. "The Big Come Down" begins with a four-second synth/static intro that is smashed apart by a hard beat at 0:05 and kaleidoscope guitars at 0:16. Critics refer to the song's lyrics in an attempt to project a narcissistic Reznor personality, but don't comment on stylistic tweaks like the AM radio influenced backing vocals at 1:02 and 1:19, or the use of guitars as a percussion layer at 1:51. A further intriguing element is the return of the fly samples at 2:38, an effect heard on previous releases and a possible post-human sub-text. The alien mythos will eventually reign over the banal and empty human. At 3:07 the synths return with static, a further overlay adds more synths at 3:45 as the track spirals to its peak, before dissipating at 3:1 in a mesh of percussion and guitars. "Underneath It All" opens with a riff that signals we have reached the album's climatic turning point, with the recurring theme of fragmenting body-memories returning at 0:23 with the line 'All I can do/I can still feel you', and being echoed by pulsing static at 0:42 as electric percussion. A 'Messiah Complex' appears at 1:34 with the line 'Crucify/After all I've died/After all I've tried/You are still inside', or at least it appears to be that on the surface. This is the kind of line that typical rock critics will quote, but a careful re-reading suggests that Reznor is pointing to the painful nature of remanifesting. Our past shapes us more than we would like to admit particularly our first relationships. "Ripe (With Decay)" is the album's final statement, a complex weaving of passages over a repetitive mesh of guitars, pulsing echoes, back-beats, soundscapes, and a powerful Mike Garson piano solo (2:26). Earlier motifs including fly samples (3:00), mournful funeral violas (3:36) and slowing time effects (4:28) recur throughout the track. Having finally reached the psychotic core, Reznor is not content to let us rest, mixing funk bass riffs (4:46), vocal snatches (5:23) and oscillating guitars (5:39) that drag the listener forever onwards towards the edge of the abyss (5:58). The final sequence begins at 6:22, loses fidelity at 6:28, and ends abruptly at 6:35. At millennium's end there is a common-held perception that the world is in an irreversible state of decay, and that Culture is just a wafer-thin veneer over anarchy. Music like The Fragile suggests that we are still trying to assimilate into popular culture the 'war-on-Self' worldviews unleashed by the nineteenth-century 'Masters of Suspicion' (Charles Darwin, Sigmund Freud, Friedrich Nietzsche). This 'assimilation gap' is evident in industrial music, which in the late 1970s was struggling to capture the mood of the Industrial Revolution and Charles Dickens, so the genre is ripe for further exploration of the scarred psyche. What the self-appointed moral guardians of the Herd fail to appreciate is that as the imprint baseline rises (reflective of socio-political realities), the kind of imagery prevalent throughout The Fragile and in films like Strange Days (1995), The Matrix (1999) and eXistenZ (1999) is going to get even darker. The solution is not censorship or repression in the name of pleasing an all-saving surrogate god-figure. No, these things have to be faced and embraced somehow. Such a process can only occur if there is space within for the Sadeian aesthetic that Nine Inch Nails embodies, and not a denial of Dark Eros. "We need a second Renaissance", notes Don Webb, "a rejuvenation of Culture on a significant scale". In other words, a global culture-shift of quantum (aeon or epoch-changing) proportions. The tools required will probably not come just from the over-wordy criticism of Cyber-culture and Cultural Studies or the logical-negative feeding frenzy of most Music Journalism. They will come from a dynamic synthesis of disciplines striving toward a unity of knowledge -- what socio-biologist Edward O. Wilson has described as 'Consilience'. Liberating tools and ideas will be conveyed to a wider public audience unfamiliar with such principles through predominantly science fiction visual imagery and industrial/electronica music. The Fragile serves as an invaluable model for how such artefacts could transmit their dreams and propagate their messages. For the hyper-alert listener, it will be the first step on a new journey. But sadly for the majority, it will be just another hysterical industrial album promoted as selection of the month. References Bester, Alfred. The Stars My Destination.

Our culture abhors the world.Yet Quicksand is swallowing the duellists; the river is threatening the fighter: earth, waters and climate, the mute world, the voiceless things once placed as a decor surrounding the usual spectacles, all those things that never interested anyone, from now on thrust themselves brutally and without warning into our schemes and manoeuvres (Michel Serres, The Natural Contract, p 3). When Michel Serres describes culture's abhorrence of the world in the opening pages of The Natural Contract he draws our attention to the sidelining of nature in histories and theories that have sought to describe Western culture. As Serres argues, cultural histories are quite often built on the debates and struggles of humanity, which are largely held apart from their natural surroundings, as if on a stage, "purified of things" (3). But, as he is at pains to point out, human activity and conflict always take place within a natural milieu, a space of quicksand, swelling rivers, shifting earth, and atmospheric turbulence. Recently, via the potential for vast environmental change, what was once thought of as a staid “nature” has reasserted itself within culture. In this paper I explore how Serres’s positioning of nature can be understood amid new communication systems, which, via the apparent dematerialization of messages, seems to have further removed culture from nature. From here, I focus on a set of artworks that work against this division, reformulating the connection between information, a topic usually considered in relation to media and anthropic communication (and something about which Serres too has a great deal to say), and nature, an entity commonly considered beyond human contrivance. In particular, I explore how information visualisation and sonification has been used to give a new sense of materiality to the atmosphere, repotentialising the air as a natural and informational entity. The Natural Contract argues for the legal legitimacy of nature, a natural contract similar in standing to Rousseau’s social contract. Serres’ss book explores the history and notion of a “legal person”, arguing for a linking of the scientific view of the world and the legal visions of social life, where inert objects and living beings are considered within the same legal framework. As such The Natural Contract does not deal with ecology per-se, but instead focuses on an argument for the inclusion of nature within law (Serres, “A Return” 131). In a drastic reconfiguring of the subject/object relationship, Serres explains how the space that once existed as a backdrop for human endeavour now seems to thrust itself directly into history. "They (natural events) burst in on our culture, which had never formed anything but a local, vague, and cosmetic idea of them: nature" (Serres, The Natural Contract 3). In this movement, nature does not simply take on the role of a new object to be included within a world still dominated by human subjects. Instead, human beings are understood as intertwined with a global system of turbulence that is both manipulated by them and manipulates them. Taking my lead from Serres’s book, in this paper I begin to explore the disconnections and reconnections that have been established between information and the natural environment. While I acknowledge that there is nothing natural about the term “nature” (Harman 251), I use the term to designate an environment constituted by the systematic processes of the collection of entities that are neither human beings nor human crafted artefacts. As the formation of cultural systems becomes demarcated from these natural objects, the scene is set for the development of culturally mediated concepts such as “nature” and “wilderness,” as entities untouched and unspoilt by cultural process (Morton). On one side of the divide the complex of communication systems is situated, on the other is situated “nature”. The restructuring of information flows due to developments in electronic communication has ostensibly removed messages from the medium of nature. Media is now considered within its own ecology (see Fuller; Strate) quite separate from nature, except when it is developed as media content (see Cubitt; Murray; Heumann). A separation between the structures of media ecologies and the structures of natural ecologies has emerged over the history of electronic communication. For instance, since the synoptic media theory of McLuhan it has been generally acknowledged that the shift from script to print, from stone to parchment, and from the printing press to more recent developments such as the radio, telephone, television, and Web2.0, have fundamentally altered the structure and effects of human relationships. However, these developments – “the extensions of man” (McLuhan)— also changed the relationship between society and nature. Changes in communications technology have allowed people to remain dispersed, as ideas, in the form of electric currents or pulses of light travel vast distances and in diverse directions, with communication no longer requiring human movement across geographic space. Technologies such as the telegraph and the radio, with their ability to seemingly dematerialize the media of messages, reformulated the concept of communication into a “quasi-physical connection” across the obstacles of time and space (Clarke, “Communication” 132). Prior to this, the natural world itself was the medium through which information was passed. Rather than messages transmitted via wires, communication was associated with the transport of messages through the world via human movement, with the materiality of the medium measured in the time it took to cover geographic space. The flow of messages followed trade flows (Briggs and Burke 20). Messages moved along trails, on rail, over bridges, down canals, and along shipping channels, arriving at their destination as information. More recently however, information, due to its instantaneous distribution and multiplication across space, seems to have no need for nature as a medium. Nature has become merely a topic for information, as media content, rather than as something that takes part within the information system itself. The above example illustrates a separation between information exchange and the natural environment brought about by a set of technological developments. As Serres points out, the word “media” is etymologically related to the word “milieu”. Hence, a theory of media should be always related to an understanding of the environment (Crocker). But humans no longer need to physically move through the natural world to communicate, ideas can move freely from region to region, from air-conditioned room to air-conditioned room, relatively unimpeded by natural forces or geographic distance. For a long time now, information exchange has not necessitated human movement through the natural environment and this has consequences for how the formation of culture and its location in (or dislocation from) the natural world is viewed. A number of artists have begun questioning the separation between media and nature, particularly concerning the materiality of air, and using information to provide new points of contact between media and the atmosphere (for a discussion of the history of ecoart see Wallen). In Eclipse (2009) (fig. 1) for instance, an internet based work undertaken by the collective EcoArtTech, environmental sensing technology and online media is used experimentally to visualize air pollution. EcoArtTech is made up of the artist duo Cary Peppermint and Leila Nadir and since 2005 they have been inquiring into the relationship between digital technology and the natural environment, particularly regarding concepts such as “wilderness”. In Eclipse, EcoArtTech garner photographs of American national parks from social media and photo sharing sites. Air quality data gathered from the nearest capital city is then inputted into an algorithm that visibly distorts the image based on the levels of particle pollution detected in the atmosphere. The photographs that circulate on photo sharing sites such as Flickr—photographs that are usually rather banal in their adherence to a history of wilderness photography—are augmented by the environmental pollution circulating in nearby capital cities. Figure 1: EcoArtTech, Eclipse (detail of screenshot), 2009 (Internet-based work available at:http://turbulence.org/Works/eclipse/) The digital is often associated with the clean transmission of information, as packets of data move from a server, over fibre optic cables, to be unpacked and re-presented on a computer's screen. Likewise, the photographs displayed in Eclipse are quite often of an unspoilt nature, containing no errors in their exposure or focus (most probably because these wilderness photographs were taken with digital cameras). As the photographs are overlaid with information garnered from air quality levels, the “unspoilt” photograph is directly related to pollution in the natural environment. In Eclipse the background noise of “wilderness,” the pollution in the air, is reframed as foreground. “We breathe background noise…Background noise is the ground of our perception, absolutely uninterrupted, it is our perennial sustenance, the element of the software of all our logic” (Serres, Genesis 7). Noise is activated in Eclipse in a similar way to Serres’s description, as an indication of the wider milieu in which communication takes place (Crocker). Noise links the photograph and its transmission not only to the medium of the internet and the glitches that arise as information is circulated, but also to the air in the originally photographed location. In addition to noise, there are parallels between the original photographs of nature gleaned from photo sharing sites and Serres’s concept of a history that somehow stands itself apart from the effects of ongoing environmental processes. By compartmentalising the natural and cultural worlds, both the historiography that Serres argues against and the wilderness photograph produces a concept of nature that is somehow outside, behind, or above human activities and the associated matter of noise. Eclipse, by altering photographs using real-time data, puts the still image into contact with the processes and informational outputs of nature. Air quality sensors detect pollution in the atmosphere and code these atmospheric processes into computer readable information. The photograph is no longer static but is now open to continual recreation and degeneration, dependent on the coded value of the atmosphere in a given location. A similar materiality is given to air in a public work undertaken by Preemptive Media, titled Areas Immediate Reading (AIR) (fig. 2). In this project, Preemptive Media, made up of Beatriz da Costa, Jamie Schulte and Brooke Singer, equip participants with instruments for measuring air quality as they walked around New York City. The devices monitor the carbon monoxide (CO), nitrogen oxides (NOx) or ground level ozone (O3) levels that are being breathed in by the carrier. As Michael Dieter has pointed out in his reading of the work, the application of sensing technology by Preemptive Media is in distinct contrast to the conventional application of air quality monitoring, which usually takes the form of extremely high resolution located devices spread over great distances. These larger air monitoring networks tend to present the value garnered from a large expanse of the atmosphere that covers individual cities or states. The AIR project, in contrast, by using small mobile sensors, attempts to put people in informational contact with the air that they are breathing in their local and immediate time and place, and allows them to monitor the small parcels of atmosphere that surround other users in other locations (Dieter). It thus presents many small and mobile spheres of atmosphere, inhabited by individuals as they move through the city. In AIR we see the experimental application of an already developed technology in order to put people on the street in contact with the atmospheres that they are moving through. It gives a new informational form to the “vast but invisible ocean of air that surrounds us and permeates us” (Ihde 3), which in this case is given voice by a technological apparatus that converts the air into information. The atmosphere as information becomes less of a vague background and more of a measurable entity that ingresses into the lives and movements of human users. The air is conditioned by information; the turbulent and noisy atmosphere has been converted via technology into readable information (Connor 186-88). Figure 2: Preemptive Media, Areas Immediate Reading (AIR) (close up of device), 2011 Throughout his career Serres has developed a philosophy of information and communication that may help us to reframe the relationship between the natural and cultural worlds (see Brown). Conventionally, the natural world is understood as made up of energy and matter, with exchanges of energy and the flows of biomass through food webs binding ecosystems together (DeLanda 120-1). However, the tendencies and structures of natural systems, like cultural systems, are also dependent on the communication of information. It is here that Serres provides us with a way to view natural and cultural systems as connected by a flow of energy and information. He points out that in the wake of Claude Shannon’s famous Mathematical Theory of Communication it has been possible to consider the relationship between information and thermodynamics, at least in Shannon’s explanation of noise as entropy (Serres, Hermes74). For Serres, an ecosystem can be conceptualised as an informational and energetic system: “it receives, stores, exchanges, and gives off both energy and information in all forms, from the light of the sun to the flow of matter which passes through it (food, oxygen, heat, signals)” (Serres, Hermes 74). Just as we are related to the natural world based on flows of energy— as sunlight is converted into energy by plants, which we in turn convert into food— we are also bound together by flows of information. The task is to find new ways to sense this information, to actualise the information, and imagine nature as more than a welter of data and the air as more than background. If we think of information in broad ranging terms as “coded values of the output of a process” (Losee 254), then we see that information and the environment—as a setting that is produced by continual and energetic processes—are in constant contact. After all, humans sense information from the environment all the time; we constantly decode the coded values of environmental processes transmitted via the atmosphere. I smell a flower, I hear bird songs, and I see the red glow of a sunset. The process of the singing bird is coded as vibrations of air particles that knock against my ear drum. The flower is coded as molecules in the atmosphere enter my nose and bind to cilia. The red glow is coded as wavelengths from the sun are dispersed in the Earth’s atmosphere and arrive at my eye. Information, of course, does not actually exist as information until some observing system constructs it (Clarke, “Information” 157-159). This observing system as we see the sunset, hear the birds, or smell the flower involves the atmosphere as a medium, along with our sense organs and cognitive and non-cognitive processes. The molecules in the atmosphere exist independently of our sense of them, but they do not actualise as information until they are operationalised by the observational system. Prior to this, information can be thought of as noise circulating within the atmosphere. Heinz Von Foester, one of the key figures of cybernetics, states “The environment contains no information. The environment is as it is” (Von Foester in Clarke, “Information” 157). Information, in this model, actualises only when something in the world causes a change to the observational system, as a difference that makes a difference (Bateson 448-466). Air expelled from a bird’s lungs and out its beak causes air molecules to vibrate, introducing difference into the atmosphere, which is then picked up by my ear and registered as sound, informing me that a bird is nearby. One bird song is picked up as information amid the swirling noise of nature and a difference in the air makes a difference to the observational system. It may be useful to think of the purpose of information as to control action and that this is necessary “whenever the people concerned, controllers as well as controlled, belong to an organised social group whose collective purpose is to survive and prosper” (Scarrott 262). Information in this sense operates the organisation of groups. Using this definition rooted in cybernetics, we see that information allows groups, which are dependent on certain control structures based on the sending and receiving of messages through media, to thrive and defines the boundaries of these groups. We see this in a flock of birds, for instance, which forms based on the information that one bird garners from the movements of the other birds in proximity. Extrapolating from this, if we are to live included in an ecological system capable of survival, the transmission of information is vital. But the form of the information is also important. To communicate, for example, one entity first needs to recognise that the other is speaking and differentiate this information from the noise in the air. Following Clarke and Von Foester, an observing system needs to be operational. An art project that gives aesthetic form to environmental processes in this vein—and one that is particularly concerned with the co-agentive relation between humans and nature—is Reiko Goto and Tim Collin’s Plein Air (2010) (fig. 3), an element in their ongoing Eden 3 project. In this work a technological apparatus is wired to a tree. This apparatus, which references the box easels most famously used by the Impressionists to paint ‘en plein air’, uses sensing technology to detect the tree’s responses to the varying CO2 levels in the atmosphere. An algorithm then translates this into real time piano compositions. The tree’s biological processes are coded into the voice of a piano and sensed by listeners as aesthetic information. What is at stake in this work is a new understanding of atmospheres as a site for the exchange of information, and an attempt to resituate the interdependence of human and non-human entities within an experimental aesthetic system. As we breathe out carbon dioxide—both through our physiological process of breathing and our cultural processes of polluting—trees breath it in. By translating these biological processes into a musical form, Collins and Gotto’s work signals a movement from a process of atmospheric exchange to a digital process of sensing and coding, the output of which is then transmitted through the atmosphere as sound. It must be mentioned that within this movement from atmospheric gas to atmospheric music we are not listening to the tree alone. We are listening to a much more complex polyphony involving the components of the digital sensing technology, the tree, the gases in the atmosphere, and the biological (breathing) and cultural processes (cars, factories and coal fired power stations) that produce these gases. Figure 3: Reiko Goto and Tim Collins, Plein Air, 2010 As both Don Ihde and Steven Connor have pointed out, the air that we breathe is not neutral. It is, on the contrary, given its significance in technology, sound, and voice. Taking this further, we might understand sensing technology as conditioning the air with information. This type of air conditioning—as information alters the condition of air—occurs as technology picks up, detects, and makes sensible phenomena in the atmosphere. While communication media such as the telegraph and other electronic information distribution systems may have distanced information from nature, the sensing technology experimentally applied by EcoArtTech, Preeemptive Media, and Goto and Collins, may remind us of the materiality of air. These technologies allow us to connect to the atmosphere; they reformulate it, converting it to information, giving new form to the coded processes in nature.AcknowledgmentAll images reproduced with the kind permission of the artists.

IntroductionSince its launch in 2005, YouTube has fast become one of the most popular video sharing sites, one of the largest sources of user generated content, and one of the most frequently visited sites globally (Burgess and Green). As YouTube’s popularity has increased, more and more people have taken up the site’s invitation to “Broadcast Yourself.” Vlogging (video blogging) on YouTube has increased in popularity, creating new genres and communities. Vlogging not only allows individuals to create their own mediated content for mass consumption—making it a site for participatory culture (Burgess and Green; Jenkins) and resembling contemporary forms of entertainment such as reality television—but it also allows individuals to engage in narrative and identity forming practices. Through filming their everyday lives, and presenting themselves on camera, YouTubers are engaging in a process of constructing and presenting their identity online. They often form communities around these identities and continue the practice in dialogue and collaboration with their communities of viewers on YouTube. Because of YouTube’s mass global reach, the ability to create one’s own mediated content and the ability to publicly play with and project different self representations becomes a powerful tool allowing YouTubers to publicly challenge social norms and encourage others to do the same. This paper will explore these features of YouTube using the recent “The Power of MAKEUP!” movement, started by NikkieTutorials, as an example. Through a virtual ethnography of the movement as developed by Christine Hine—following the people, dialogue, connections, and narratives that emerged from Nikkie’s original video—this paper will demonstrate that YouTube is not only a tool for self transformation, but has wider potential to transform norms in society. This is achieved mainly through mobilising communities that form around transformative practices, such as makeup transformations, on YouTube. Vlogging as an Identity Forming Practice Vlogging on YouTube is a contemporary form of autobiography in which individuals engage in a process of documenting their life on a daily or weekly basis and, in doing so, constructing their identity online. Although the aim of beauty vlogs is to teach new makeup techniques, demonstrate and review new products, or circulate beauty-related information, the videos include a large amount of self-disclosure. Beauty vloggers reveal intimate things about themselves and actively engage in the practice of self-representation while filming. Beauty vlogging is unique to other vlogging genres as it almost always involves an immediate transformation of the physical self in each video. The vloggers typically begin with their faces bare and “natural” and throughout the course of the video transform their faces into how they want to be seen, and ultimately, who they want to be that day, using makeup. Thus the process of self-representation is multi-dimensional as not only are they presenting the self, but they are also visually constructing the self on camera. The construction of identity that beauty vloggers engage in on YouTube can be likened to what Robert Ezra Park and later Erving Goffman refer to as the construction and performance of a mask. In his work Race and Culture, Park states that the original meaning of the word person is a mask (249). Goffman responds to this statement in his work The Presentation of Self in Everyday Life, saying the mask is “our truer self, the self we would like to be” (30). Beauty vloggers are engaging in the process of constructing their mask—their truer self and the self they would like to be—both through their performance on YouTube, and through the visual transformation that takes place on camera. Their performance on YouTube not only communicates a desired identity, but through their performance they realise this identity. The process of filming and the visual process of constructing or transforming the self on camera through makeup brings the subject into being. Scholarship in the fields of Life Writing and Digital Media including Autobiography, Automedia and Persona Studies has acknowledged and explored the ways narratives and identities—both online and offline—are constructed, created, shaped, chosen, and invented by the individual/author (Garner; Bridger; Eakin; Maguire; Poletti and Rak; Marshall; Smith and Watson). It is widely accepted that all representations of the self are constructed. Crucially, it is the process of documenting or communicating the self that is identity forming (Richardson; Bridger), as the process, including writing, filming, and posting, brings the subject or self into being (Neuman). The individual embodies their performance and realises the self through it. Park and Goffman argue that we all engage in this process of performing and realising the self through the roles we play in society. The significance of the beauty vlogger performance and transformation is the space in which it occurs and the community that it fosters. YouTube as a Transformative Tool and MirrorThe space in which beauty vloggers play with and transform the self on camera is significant as digital technologies such as YouTube invite exploration of the self. Networked digital media (Meikle and Young) invite multiplicity, heterogeneity, and fragmentation in/of identity performances (Bolter; Gergen; Turkle, "Parallel Lives"). These technologies create opportunities for defining and re-defining the self (Bolter 130), as they allow people to present a more multi-mediated self, using both audio-visual components and text (Papacharissi 643).YouTube, in particular, allows the individual to experiment with the self, and document an ongoing transformation, through film (Kavoori). Many scholars have described this ongoing process of identity construction online using the metaphor of “the mirror” (see Kavoori; Raun; and Procter as recent examples). In his research on trans gender vlogging on YouTube, Tobias Raun explores the theme of the mirror. He describes vlogging as a “transformative medium for working on, producing and exploring the self” (366). He argues the vlog acts as a mirror allowing the individual to try out and assume various identities (366). He writes, the mirroring function of the vlog “invites the YouTuber to assume the shape of a desired identity/representation, constantly assuming and evaluating oneself as an attractive image, trying out different ‘styles of the flesh’ (Butler 177), poses and appearances” (367). In reference to trans gender vlogging, Raun writes, “The vlog seems to serve an important function in the transitioning process, and is an important part of a process of self-invention, serving as a testing ground for experimentations with, and manifestations of (new) identities” (367). The mirror (vlog) gives the individual a place/space to construct and perform their mask (identity), and an opportunity to see the reflection and adjust the mask (identity) accordingly. An important feature of the vlog as a mirror is the fact that it is less like a conventional mirror and more like a window with a reflective surface. On YouTube the vlog always involves an audience, who not only watch the performance, but also respond to it. This is in keeping with Goffman’s assertion that there is always an audience involved in any performance of the self. On YouTube, Raun argues, “the need to represent oneself goes hand in hand with the need to connect and communicate” (Raun 369). Networked digital media such as YouTube are inherently social. They invite participation (Smith; Sauter)and community through community building functions such as the ability to like, subscribe, and comment. Michael Strangelove refers to YouTube as a social space, “as a domain of self-expression, community and public confession” (4). The audience and community are important in the process of identity construction and representation as they serve a crucial role in providing feedback and encouragement, legitimising the identity being presented. As Raun writes, the vlog is an opportunity “for seeing one’s own experiences and thoughts reflected in others” (366). Raun identifies that for the trans gender vloggers in his study, simply knowing there is an audience watching their vlogs is enough to affirm their identity. He writes the vlog can be both “an individual act of self validation and . . . a social act of recognition and encouragement” (368). However, in the case of beauty vlogging the audience do more than watch, they form communities embodying and projecting the performance in everyday life and thus collectively challenge social norms, as seen in the “The Power of MAKEUP!” movement. Exploring the “The Power of MAKEUP!” MovementOn 10 May 2015, Nikkie, a well-known beauty vlogger, uploaded a video to her YouTube channel NikkieTutorials titled “The Power of MAKEUP!” Nikkie’s video can be watched here. In her video Nikkie challenges “makeup shaming,” arguing that makeup is not only fun, but can “transform” you into who you want to be. Inspired by an episode of the reality television show RuPaul’s Drag Race, in which the competing drag queens transform half of their face into “glam” (drag), and leave the other half of their face bare (male), Nikkie demonstrates that anyone can use makeup as a transformative tool. In her video Nikkie mirrors the drag queen transformations, transforming half her face into “glam” and leaving the other half of her face bare, as shown in Figure 1. In only transforming half of her face, Nikkie emphasises the scope of the transformation, demonstrating just how much you can change your appearance using only makeup on your face. Nikkie’s video communicates that both a transformed “glam” image and an “unedited” image of the self are perfectly fine, “there are no rules” and neither representations of the self should bring you shame. Figure 1: thumbnail of Nikkie’s videoNikkie’s video started a movement and spread throughout the beauty community on YouTube as a challenge. Other famous beauty vloggers, and everyday makeup lovers, took on the challenge of creating YouTube videos or posting pictures on Instagram of their faces half bare and half transformed using makeup with the tag #thepowerofmakeupchallenge. Since its release in May 2015, Nikkie’s video has been watched over thirty million times, has been liked over five hundred and thirty thousand times, and has received over twenty three thousand comments, many of which echo Nikkie’s experience of “makeup shaming.” “The power of makeup” video went viral and was picked up not only by the online beauty community but also by mainstream media with articles by Huffington Post, Yahoo.com, Marie Claire, BuzzFeed, DailyLife, POPSUGAR, Enews, Urbanshowbiz, BoredPanda, and kickvick among others. On Instagram, thousands of everyday makeup lovers have recreated the transformation and uploaded their pictures of the finished result. Various hashtags have been created around this movement and can be searched on Instagram including #thepowerofmakeupchallenge, #powerofmakeupchallenge, #powerofmakeup. Nikkie’s Instagram page dedicated to the challenge can be seen here. “The power of makeup” video is a direct reaction against what Nikkie calls “makeup shaming”—the idea that makeup is bad, and the assumption that the leading motivation for using makeup is insecurity. In her video Nikkie also reacts to the idea that the made-up-girl is “not really you,” or worse is “fake.” In the introduction to her video Nikkie says,I’ve been noticing a lot lately that girls have been almost ashamed to say that they love makeup because nowadays when you say you love makeup you either do it because you want to look good for boys, you do it because you’re insecure, or you do it because you don’t love yourself. I feel like in a way lately it’s almost a crime to love doing your makeup. So after last weeks RuPaul’s Drag Race with the half drag half male, I was inspired to show you the power of makeup. I notice a lot that when I don’t wear makeup and I have my hair up in a bun and I meet people and I show them picture of my videos or, or whatever looks I have done, they look at me and straight up tell me “that is not you.” They tell me “that’s funny” because I don’t even look like that girl on the picture. So without any further ado I’m going to do half my face full on glam—I’m truly going to transform one side of my face—and the other side is going to be me, raw, unedited, nothing, me, just me. So let’s do it.In her introduction, Nikkie identifies a social attitude that many of her viewers can relate to, that the made-up face isn’t the “real you.” This idea reveals an interesting contradiction in social attitude. As this issue of Media/Culture highlights, the theme of transformation is increasingly popular in contemporary society. Renovation shows, weight loss shows, and “makeover” shows have increased in number and popularity around the world (Lewis). Tania Lewis attributes this to an international shift towards “the real” on television (447). Accompanying this turn towards “the real,” confession, intimacy, and authenticity are now demanded and consumed as entertainment (Goldthwaite; Dovey; King). Sites such as YouTube are arguably popular because they offer real stories, real lives, and have a core value of authenticity (Strangelove; Wesch; Young; Tolson). The power of makeup transformations are challenging because they juxtapose a transformation against the natural, on the self. By only transforming half their face, the beauty vloggers juxtapose the “makeover” (transformation) with “authenticity” (the natural). The power of makeup movement is therefore caught between two contemporary social values. However, the desire for authenticity, and the lack of acceptance that the transformed image is authentic seems to be the main criticism that the members of this movement receive. Beauty vloggers identify a strong social value that “natural” is “good” and any attempt to alter the natural is taboo. Even in the commercial world “natural beauty” is celebrated and features heavily in the marketing and advertising campaigns of popular beauty, cosmetic, and skincare brands. Consider Maybelline’s emphasis on “natural beauty” in their byline “Maybe she’s born with it. Maybe it’s Maybelline.” This is not the way the members of “the power of makeup” movement use and celebrate makeup. They use and celebrate makeup as a transformative and identity forming tool, and their use of makeup is most often criticised for not being natural. In her recreation of Nikkie’s video, Evelina Forsell says “people get upset when I’m not natural.” Like Nikkie, Evelina reveals she often receives the criticism that “the person with a full on face with makeup is not you.” Evelina’s video can be watched here.“The power of makeup” movement and its participants challenge this criticism that the made-up self is not the “real” self. Evelina directly responds to this criticism in her video, stating “when I have a full face of makeup . . . that’s still me, but a more . . . creative me, I guess.” The beauty vloggers in this movement use makeup and YouTube as extensions of the self, as tools for self-expression, self-realisation, and ongoing transformation. Beauty vloggers are demonstrating that makeup is a tool and extension of the self that allows them to explore and play with their self-representations. In the same way that technology enables the individual to extend and “reinvent him/herself online” (Papacharissi 645), so does makeup. And in the same way that technology becomes an extension of the self, or even a second self (Turkle, The Second Self; Vaast) so does makeup. Makeup is a tool and technique of the self. Vlogging is about storytelling (Kavoori), but it is also collective—it’s about telling collective stories (Raun 373) which can be seen in various vlogging genres. As Geert Lovink suggests, YouTube is one of the largest databases of global shared experience. YouTube’s global popularity can be attributed to Strangelove’s assertion that “there’s nothing more interesting to real people . . . than authentic stories told about other real people” (65). Individuals are drawn to Nikkie’s experience, seeing themselves reflected in her story. Famous beauty vloggers on YouTube, and everyday beauty lovers, find community in the collective experience of feeling shame for loving makeup and using makeup to transform and communicate their identity. Effectively, the movement forms communities of practice (Wenger) made up of hundreds of people brought together by the shared value and use of makeup as a transformative tool. The online spaces where these activities take place (mainly on YouTube and Instagram) form affinity spaces (Gee) where the community come together, share information, learn and develop their practice. Hundreds of YouTubers from all over the world took up Nikkie’s invitation to demonstrate the power of makeup by transforming themselves on camera. From well-established beauty vloggers with millions of viewers, to amateur beauty lovers with YouTube channels, many people felt moved by Nikkie’s example and embodied the message, adapting the transformation to suit their circumstances. The movement includes both men and women, children and adults. Some transformations are inspirational such as Shalom Blac’s in which she talks about accepting the scars that are all over her face, but also demonstrates how makeup can make them disappear. Shalom has almost five million views on her “POWER OF MAKEUP” video, and has been labelled “inspirational” by the media. Shalom Blac’s video can be watched here and the media article labelling her as “inspirational” can be viewed here. Others, such as PatrickStarrr, send a powerful message that “It’s okay to be yourself.” Unlike a traditional interpretation of that statement, Patrick is communicating that it is okay to be the self that you construct, on any given day. Patrick also has over four million views on his video which can be watched here. During her transformation, Nikkie points out each feature of her face that she does not like and demonstrates how she can change it using makeup. Nikkie’s video is primarily a tutorial, educating viewers on different makeup techniques that can manipulate the appearance of their natural features into how they would like them to appear. These techniques are also reproduced and embodied through the various contributors to the movement. Thus the tutorial is an educational tool enabling others to use makeup for their own self representations (see Paul A. Soukup for an overview of YouTube as an educational tool). A feminist perspective may deconstruct the empowering, educational intentions of Nikkie’s video, insisting that conceptions of beauty are a social construct (Travis, Meginnis, and Bardari) and should not be re-enforced by encouraging women (and men) to use make-up to feel good. However, this sort of discourse does not appear in the movement, and this paper seeks to analyse the movement as its contributors frame and present it. Rather, “the power of makeup” movement falls within a postfeminist framework celebrating choice, femininity, independence, and the individual construction of modern identity (McRobbie; Butler; Beck, Giddens and Lash). Postfeminism embraces postmodern notions of identity in which individuals are “called up to invent their own structures” (McRobbie 260). Through institutions such as education young women have “become more independent and able,” and “‘dis-embedded’ from communities where gender roles were fixed” (McRobbie 260). Angela McRobbie attributes this to the work of scholars such as Anthony Giddens and Ulrich Beck and their emphasis on individualisation and reflexive modernisation. These scholars take a Foucauldian approach to identity construction in the modern age, where the individual must choose their own structures “internally and individualistically” (260), engaging in an ongoing process of self-monitoring and self-improvement, and resulting in the current self-help culture (McRobbie). In addition to being an educational and constructive tool, Nikkie’s video is also an exercise in self-branding and self-promotion(see Marwick; Duffy and Hund; and van Nuenen for scholarship on self-branding). Through her ongoing presence on YouTube, presenting this video in conjunction with her other tutorials, Nikkie is establishing herself as a beauty vlogger/guru. Nikkie lists all of the products that she uses in her transformation below her video with links to where people can buy them. She also lists her social media accounts, ways that people can connect with her, and other videos that people might be interested in watching. There are also prompts to subscribe, both during her video and in the description bar below her video. Nikkie’s transformation is both an ongoing endeavour to create her image and public persona as a beauty vlogger, and a physical transformation on camera. There is also a third transformation that takes place because her vlog is in the public sphere and consequently mobilises a movement. The transformation is of the way people talk about and eventually perceive makeup. Nikkie’s video aims to end makeup shaming and promote makeup as an empowering tool. With each recreation of her video, with each Instagram photo featuring the transformation, and with each mainstream media article featuring the movement, #thepowerofmakeup movement community are transforming the image of the made-up girl—transforming the association of makeup with presenting an inauthentic identity—in society. ConclusionThe “The Power of MAKEUP!” movement, started by NikkieTutorials, demonstrates one way in which people are using YouTube as a transformative tool, and mirror, to document, construct, and present their identity online, using makeup. Through their online transformation the members of the movement not only engage in a process of constructing and presenting their identity, but they form communities who share a love of makeup and its transformative potential. By embodying Nikkie’s original message to rid makeup shaming and transform the self into a desired identity, the movement re-enforces the “made-up” image of the self as real and authentic, and challenges conceptions that the “made-up” image is “fake” and inauthentic. Ultimately, this case study explores YouTube as a site that allows individuals to play with, construct, and present their identity. YouTube is a tool with which, and a space in which, people can transform themselves, and in doing so create communities which can work together to publicly challenge social norms.References Beck, Ulrich, Anthony Giddens, and Scott Lash.
