Journal articles on the topic 'Q-ary block codes'

Progressive-edge-growth (PEG) algorithm is one of the best known methods for constructing LDPC codes at short and intermediate block lengths, however, the codes directly designed by such algorithm has high encoding complexity, especially for q-ary LDPC codes, encoding complexity increases with the increase of q value rapidly, which hinder the development of q-ary LDPC code’s implementation seriously. To such problem, the paper presents a improved method based on PEG algorithm which can be encoded by the iterative encoding algorithm with the liner operation complexity. The simulation results indicate: Though the error correcting capability of irregular q-ary LDPC codes constructed by the proposed methods in the paper is basically identical with the codes constructed by the PEG algorithm, but the powerful advantage makes it be easily implemented by the hardware .

Matrix embedding (ME) code is a commonly used steganography technique, which uses linear block codes to improve embedding efficiency. However, its main disadvantage is the inability to perform maximum likelihood decoding due to the high complexity of decoding large ME codes. As such, it is difficult to improve the embedding efficiency. The proposed q-ary embedding code can provide excellent embedding efficiency and is suitable for various embedding rates (large and small payloads). This article discusses that by using perforation technology, a convolutional code with a high embedding rate can be easily converted into a convolutional code with a low embedding rate. By keeping the embedding rate of the (2, 1) convolutional code unchanged, convolutional codes with different embedding rates can be designed through puncturing.

AbstractLet S, T be subshifts of finite type, with Markov measures p, q on them, and let φ: (S, p) → (T, q) be a block code. Let Ip, Iq denote the information cocycles of p, q. For a subshift of finite type ⊂T, the pressure of equals that of . Applying this to Bernoulli shifts and using finiteness conditions on Perron numbers, we have the following. If the probability vector p = (p1…, pk+1) is such that the distinct transcendental elements of {p1/pk+1…pk/pk+1) are algebraically independent then the Bernoulli shift B(p) has finitely many Bernoulli images by block codes.

The paper discusses weight distribution of periodic errors and then the optimal case on bounds of parity check digits for (n=n1+n2,k) linear codes overGF(q)that corrects all periodic errors of orderrin the first block of lengthn1and all periodic errors of ordersin the second block of lengthn2and no others. Further, we extend the study to the case when the errors are in the form of periodic errors of orderr(ands) or more in the two subblocks.

Costume Color Samples from the Rural Areas in Northern and Southern Regions of China during the Republic Period Were Collected, Measured with a Spectrophotometer, and the Symbolization of Colors as Cultural Codes Were Analyzed by the Q-model. the Results Show that Red,Blue and Black which Are Included in the Traditional Five Colors System Are More Frequently-used Colors in the Northern Region, and Dark Grayish Blue and Black Are More Significant Colors of High Frequency in the Southern Region. these Colors All Acted as Cultural Codes with Cultural Significance. this Paper Furthers Understanding of Color Symbology from Perspective of Cultural Semiotics Focused on Folk Costume Colors.

AbstractA new family of two-dimensional optical hybrid code which employs zero cross-correlation (ZCC) codes, constructed by the balanced incomplete block design BIBD, as both time-spreading and wavelength hopping patterns are used in this paper. The obtained codes have both off-peak autocorrelation and cross-correlation values respectively equal to zero and unity. The work in this paper is a computer experiment performed using Optisystem 9.0 software program as a simulator to determine the wavelength hopping/time spreading (WH/TS) OCDMA system performances limitations. Five system parameters were considered in this work: the optical fiber length (transmission distance), the bitrate, the chip spacing and the transmitted power. This paper shows for what sufficient system performance parameters (BER≤10−9, Q≥6) the system can stand for.

We analyze the head-on collision of two boosted Schwarzschild black holes and the mass-energy loss of the system by gravitational wave emission, in the realm of Robinson-Trautman (RT) spacetimes. The characteristic initial data for the problem are constructed, and evolved by RT equation integrated by numerical codes based on the Galerkin method. The emission of gravitational waves is typical bremsstrahlung at early times and the final configuration is that of a boosted black hole with larger (Bondi) rest mass and smaller velocity parameter. The efficiency Δ of the process of energy extraction by gravitational radiation is evaluated and satisfies a nonextensive distribution with entropic index q ≃ 1/2. The final momentum of the remnant black hole has a maximum which depends on the ratio of the masses of the initial black holes.

In today’s modern telecommunications systems, makes the number of studies and development of multiple antennas and multiple-input multiple-output (MIMO) systems to achieve high reliability and low complexity. One attractive approach to improve that performance is using technique transmit diversity which is spacetime block coding and receiver diversity i.e. zero forcing EVCM (ZF EVCM). Although some earlier MIMO standards were develop some space-time codes like (O-STBC)and (Q-OSTBC) to provide high reliability but they are limited able to achieve orthogonality. In this research will be proposed a MIMO system scheme which is an improvement of QOSTBC that used a transmission diversity technique. This improvement from QOSTBC is Twice QOSTBC uses a provision in two codeword matrices to be sent are arranged diagonally so as to have higher levels of orthogonality. In this case Twice QOSTBC highly structured (4x1) can be replaced as an equivalent EVCM channel H. The proposed Twice-QOSTBC’s results outperform other QOSTBC techniques with a difference around 3 dB for single-input multi-input (MISO) input configuration at 10-6 BER and receiver ZF EVCM has a very similar structure as the code matrix S of the underlying Twice QSTBC which can eliminates the system complexity.

Abstract Background: Epidemiology and outcome of myelodysplastic syndromes (MDS) in the United States is not well recognized. MDS became reportable to the Surveillance, Epidemiology, and End Results program (SEER) in 2001. Only one study is published examining the SEER data between 2001–2003 on MDS incidence, epidemiology and outcome. We report first study of MDS among large population in the Veteran Affair system. Methods: There are approximately 127 VA Medical Centers diagnosing and/or treating Cancer patients. The data collected by the medical centers cancer registries is aggregated as the VA Central Cancer Registry (VACCR) and is maintained by the Chief Program Office for Oncology at VA in Washington DC. We used the VACCR to analyze VA patients with MDS diagnosed between 1995 and 2005. The data was downloaded from the database using ICD-03 histology codes for MDS. Data was entered and analyzed using bio-statistical software SPSS. Kaplan-Meier curves were used for estimates of overall survival, chi square for comparison of categorical variables and t-test for continuous variables. Results: Between 1995 and 2005, 1411 MDS cases were registered in the VACCR database. The median age was 75 years. Among those 1379 (97.7%) were males and 1196 (84.4%) were white patients, 171 (12.1%) black, and 44 (3.5%) other race. Majority of cases were reported as MDS, NOS 935 (66.3%), Refractory anemia (RA) 180 (12.8%), Refractory anemia with ring sideroblasts (RARS) 105 (7.4%), Refractory anemia with multilineage dysplasia (RCMD) 22 (1.6%), 5 q syndrome 13 (0.9%), Refractory anemia with excess blasts (RAEB) 105 (7.4%), Refractory anemia with excess blast in transformation 17 (1.2%), and therapy related MDS (t-MDS) 34 (2.4%). No IPSS data were available. The median overall survival (OS) was 1.8 year (95% CI 1.5–2.1). The 3 year and 5 year overall survival was 30% and 22% respectively. The median OS for RA patients was 3.7 year, RARS 4.9 year and for RAEB was 0.8 year. No difference was observed in OS between whites and black (median OS 1.73 versus 2.65, p value 0.28). Their was a non statistically significant trend for improvement of OS in patients diagnosed in 2004–2005 compared to 1995–2003 (time where azacitidine and lenalidomide were approved) median OS of 3.2 versus 1.8 (p value 0.64). Conclusion: This is the first report of MDS case series in the VA system. Outcome is similar to what is described in literature and SEER data (3 Year OS was 30% in our VA population study compared to 35% in recently published SEER data). No racial disparities are observed in outcome. A trend towards better overall survival is noted in the last 2 years since approval of new treatment options. Coding for WHO subtypes, IPSS and treatment options should be considered in all large MDS registries.

This study aimed to explore the perceived barriers to physical activity among college students Study Design: Qualitative research design Eight focus group discussions on 67 college students aged 18-24 years (48 females, 19 males) was conducted on College premises. Data were analysed using inductive approach. Participants identified a number of obstacles to physical activity. Perceived barriers emerged from the analysis of the data addressed the different dimensions of the socio-ecological framework. The result indicated that the young adults perceived substantial amount of personal, social and environmental factors as barriers such as time constraint, tiredness, stress, family control, safety issues and much more. Understanding the barriers and overcoming the barriers at this stage will be valuable. Health professionals and researchers can use this information to design and implement interventions, strategies and policies to promote the participation in physical activity. This further can help the students to deal with those barriers and can help to instil the habit of regular physical activity in the later adult years.

A code $C$ in the Hamming graph $\varGamma=H(m,q)$ is $2$-neighbour-transitive if ${\rm Aut}(C)$ acts transitively on each of $C=C_0$, $C_1$ and $C_2$, the first three parts of the distance partition of $V\varGamma$ with respect to $C$. Previous classifications of families of $2$-neighbour-transitive codes leave only those with an affine action on the alphabet to be investigated. Here, $2$-neighbour-transitive codes with minimum distance at least $5$ and that contain ``small'' subcodes as blocks of imprimitivity are classified. When considering codes with minimum distance at least $5$, completely transitive codes are a proper subclass of $2$-neighbour-transitive codes. This leads, as a corollary of the main result, to a solution of a problem posed by Giudici in 1998 on completely transitive codes.

Effective detectors with low-complexity are considered for the Alamouti’s multiuser space-time block coded (STBC) systems. Viewing the noiseless received signals from Q users as a lattice with basis vectors being the columns of the total channel matrix H, we apply lattice reduction to transform the original basis into a nearly orthogonal one which improves the decision regions against noise. Then, linear detection using zero-forcing (ZF) and minimum-mean-square-error (MMSE) methods is performed on the transformed basis to detect transmitted signals from the Q users. These lattice-reduction-aided (LRA) linear detectors significantly improve BER of the linear detectors and, more importantly, allow us to achieve full diversity at high Eb/N0 regions.

Traditionally, modes of Message Authentication Codes(MAC) such as Cipher Block Chaining (CBC) are instantiated using block ciphers or keyed Pseudo Random Permutations(PRP). However, one can also use domain preserving keyed Pseudo Random Functions(PRF) to instantiate MAC modes. The very first security proof of CBC-MAC [BKR00], essentially modeled the PRP as a PRF. Until now very little work has been done to investigate the difference between PRP vs PRF instantiations. Only known result is the rather loose folklore PRP-PRF transition of any PRP based security proof, which looses a factor of Ο( σ2/2n ) (domain of PRF/PRP is {0, 1}n and adversary makes σ many PRP/PRF calls in total). This loss is significant, considering the fact tight Θ( q2/2n ) security bounds have been known for PRP based EMAC and ECBC constructions (where q is the total number of adversary queries). In this work, we show for many variations of encrypted CBC MACs (i.e. EMAC, ECBC, FCBC, XCBC and TCBC), random function based instantiation has a security bound Ο( qσ/2n ). This is a significant improvement over the folklore PRP/PRF transition. We also show this bound is optimal by providing an attack against the underlying PRF based CBC construction. This shows for EMAC, ECBC and FCBC, PRP instantiations are substantially more secure than PRF instantiations. Where as, for XCBC and TMAC, PRP instantiations are at least as secure as PRF instantiations.

From elephants to ABBA fans, silicon to hormone, the following discussion uses a new research method to look at printed text, motion pictures and a teenage rebel icon. If by ‘print’ we mean a mechanically reproduced impression of a cultural symbol in a medium, then printing has been with us since before microdot security prints were painted onto cars, before voice prints, laser prints, network servers, record pressings, motion picture prints, photo prints, colour woodblock prints, before books, textile prints, and footprints. If we accept that higher mammals such as elephants have a learnt culture, then it is possible to extend a definition of printing beyond Homo sapiens. Poole reports that elephants mechanically trumpet reproductions of human car horns into the air surrounding their society. If nothing else, this cross-species, cross-cultural reproduction, this ‘ability to mimic’ is ‘another sign of their intelligence’. Observation of child development suggests that the first significant meaningful ‘impression’ made on the human mind is that of the face of the child’s nurturer – usually its mother. The baby’s mind forms an ‘impression’, a mental print, a reproducible memory data set, of the nurturer’s face, voice, smell, touch, etc. That face is itself a cultural construct: hair style, makeup, piercings, tattoos, ornaments, nutrition-influenced skin and smell, perfume, temperature and voice. A mentally reproducible pattern of a unique face is formed in the mind, and we use that pattern to distinguish ‘familiar and strange’ in our expanding social orbit. The social relations of patterned memory – of imprinting – determine the extent to which we explore our world (armed with research aids such as text print) or whether we turn to violence or self-harm (Bretherton). While our cultural artifacts (such as vellum maps or networked voice message servers) bravely extend our significant patterns into the social world and the traversed environment, it is useful to remember that such artifacts, including print, are themselves understood by our original pattern-reproduction and impression system – the human mind, developed in childhood. The ‘print’ is brought to mind differently in different discourses. For a reader, a ‘print’ is a book, a memo or a broadsheet, whether it is the Indian Buddhist Sanskrit texts ordered to be printed in 593 AD by the Chinese emperor Sui Wen-ti (Silk Road) or the US Defense Department memo authorizing lower ranks to torture the prisoners taken by the Bush administration (Sanchez, cited in ABC). Other fields see prints differently. For a musician, a ‘print’ may be the sheet music which spread classical and popular music around the world; it may be a ‘record’ (as in a ‘recording’ session), where sound is impressed to wax, vinyl, charged silicon particles, or the alloys (Smith, “Elpida”) of an mp3 file. For the fine artist, a ‘print’ may be any mechanically reproduced two-dimensional (or embossed) impression of a significant image in media from paper to metal, textile to ceramics. ‘Print’ embraces the Japanese Ukiyo-e colour prints of Utamaro, the company logos that wink from credit card holographs, the early photographs of Talbot, and the textured patterns printed into neolithic ceramics. Computer hardware engineers print computational circuits. Homicide detectives investigate both sweaty finger prints and the repeated, mechanical gaits of suspects, which are imprinted into the earthy medium of a crime scene. For film makers, the ‘print’ may refer to a photochemical polyester reproduction of a motion picture artifact (the reel of ‘celluloid’), or a DVD laser disc impression of the same film. Textualist discourse has borrowed the word ‘print’ to mean ‘text’, so ‘print’ may also refer to the text elements within the vision track of a motion picture: the film’s opening titles, or texts photographed inside the motion picture story such as the sword-cut ‘Z’ in Zorro (Niblo). Before the invention of writing, the main mechanically reproduced impression of a cultural symbol in a medium was the humble footprint in the sand. The footprints of tribes – and neighbouring animals – cut tracks in the vegetation and the soil. Printed tracks led towards food, water, shelter, enemies and friends. Having learnt to pattern certain faces into their mental world, children grew older and were educated in the footprints of family and clan, enemies and food. The continuous impression of significant foot traffic in the medium of the earth produced the lines between significant nodes of prewriting and pre-wheeled cultures. These tracks were married to audio tracks, such as the song lines of the Australian Aborigines, or the ballads of tramping culture everywhere. A typical tramping song has the line, ‘There’s a track winding back to an old-fashion shack along the road to Gundagai,’ (O’Hagan), although this colonial-style song was actually written for radio and became an international hit on the airwaves, rather than the tramping trails. The printed tracks impressed by these cultural flows are highly contested and diverse, and their foot prints are woven into our very language. The names for printed tracks have entered our shared memory from the intersection of many cultures: ‘Track’ is a Germanic word entering English usage comparatively late (1470) and now used mainly in audio visual cultural reproduction, as in ‘soundtrack’. ‘Trek’ is a Dutch word for ‘track’ now used mainly by ecotourists and science fiction fans. ‘Learn’ is a Proto-Indo-European word: the verb ‘learn’ originally meant ‘to find a track’ back in the days when ‘learn’ had a noun form which meant ‘the sole of the foot’. ‘Tract’ and ‘trace’ are Latin words entering English print usage before 1374 and now used mainly in religious, and electronic surveillance, cultural reproduction. ‘Trench’ in 1386 was a French path cut through a forest. ‘Sagacity’ in English print in 1548 was originally the ability to track or hunt, in Proto-Indo-European cultures. ‘Career’ (in English before 1534) was the print made by chariots in ancient Rome. ‘Sleuth’ (1200) was a Norse noun for a track. ‘Investigation’ (1436) was Latin for studying a footprint (Harper). The arrival of symbolic writing scratched on caves, hearth stones, and trees (the original meaning of ‘book’ is tree), brought extremely limited text education close to home. Then, with baked clay tablets, incised boards, slate, bamboo, tortoise shell, cast metal, bark cloth, textiles, vellum, and – later – paper, a portability came to text that allowed any culture to venture away from known ‘foot’ paths with a reduction in the risk of becoming lost and perishing. So began the world of maps, memos, bills of sale, philosophic treatises and epic mythologies. Some of this was printed, such as the mechanical reproduction of coins, but the fine handwriting required of long, extended, portable texts could not be printed until the invention of paper in China about 2000 years ago. Compared to lithic architecture and genes, portable text is a fragile medium, and little survives from the millennia of its innovators. The printing of large non-text designs onto bark-paper and textiles began in neolithic times, but Sui Wen-ti’s imperial memo of 593 AD gives us the earliest written date for printed books, although we can assume they had been published for many years previously. The printed book was a combination of Indian philosophic thought, wood carving, ink chemistry and Chinese paper. The earliest surviving fragment of paper-print technology is ‘Mantras of the Dharani Sutra’, a Buddhist scripture written in the Sanskrit language of the Indian subcontinent, unearthed at an early Tang Dynasty site in Xian, China – making the fragment a veteran piece of printing, in the sense that Sanskrit books had been in print for at least a century by the early Tang Dynasty (Chinese Graphic Arts Net). At first, paper books were printed with page-size carved wooden boards. Five hundred years later, Pi Sheng (c.1041) baked individual reusable ceramic characters in a fire and invented the durable moveable type of modern printing (Silk Road 2000). Abandoning carved wooden tablets, the ‘digitizing’ of Chinese moveable type sped up the production of printed texts. In turn, Pi Sheng’s flexible, rapid, sustainable printing process expanded the political-cultural impact of the literati in Asian society. Digitized block text on paper produced a bureaucratic, literate elite so powerful in Asia that Louis XVI of France copied China’s print-based Confucian system of political authority for his own empire, and so began the rise of the examined public university systems, and the civil service systems, of most European states (Watson, Visions). By reason of its durability, its rapid mechanical reproduction, its culturally agreed signs, literate readership, revered authorship, shared ideology, and distributed portability, a ‘print’ can be a powerful cultural network which builds and expands empires. But print also attacks and destroys empires. A case in point is the Spanish conquest of Aztec America: The Aztecs had immense libraries of American literature on bark-cloth scrolls, a technology which predated paper. These libraries were wiped out by the invading Spanish, who carried a different book before them (Ewins). In the industrial age, the printing press and the gun were seen as the weapons of rebellions everywhere. In 1776, American rebels staffed their ‘Homeland Security’ units with paper makers, knowing that defeating the English would be based on printed and written documents (Hahn). Mao Zedong was a book librarian; Mao said political power came out of the barrel of a gun, but Mao himself came out of a library. With the spread of wireless networked servers, political ferment comes out of the barrel of the cell phone and the internet chat room these days. Witness the cell phone displays of a plane hitting a tower that appear immediately after 9/11 in the Middle East, or witness the show trials of a few US and UK lower ranks who published prints of their torturing activities onto the internet: only lower ranks who published prints were arrested or tried. The control of secure servers and satellites is the new press. These days, we live in a global library of burning books – ‘burning’ in the sense that ‘print’ is now a charged silicon medium (Smith, “Intel”) which is usually made readable by connecting the chip to nuclear reactors and petrochemically-fired power stations. World resources burn as we read our screens. Men, women, children burn too, as we watch our infotainment news in comfort while ‘their’ flickering dead faces are printed in our broadcast hearths. The print we watch is not the living; it is the voodoo of the living in the blackout behind the camera, engaging the blood sacrifice of the tormented and the unfortunate. Internet texts are also ‘on fire’ in the third sense of their fragility and instability as a medium: data bases regularly ‘print’ fail-safe copies in an attempt to postpone the inevitable mechanical, chemical and electrical failure that awaits all electronic media in time. Print defines a moral position for everyone. In reporting conflict, in deciding to go to press or censor, any ‘print’ cannot avoid an ethical context, starting with the fact that there is a difference in power between print maker, armed perpetrators, the weak, the peaceful, the publisher, and the viewer. So many human factors attend a text, video or voice ‘print’: its very existence as an aesthetic object, even before publication and reception, speaks of unbalanced, and therefore dynamic, power relationships. For example, Graham Greene departed unscathed from all the highly dangerous battlefields he entered as a novelist: Riot-torn Germany, London Blitz, Belgian Congo, Voodoo Haiti, Vietnam, Panama, Reagan’s Washington, and mafia Europe. His texts are peopled with the injustices of the less fortunate of the twentieth century, while he himself was a member of the fortunate (if not happy) elite, as is anyone today who has the luxury of time to read Greene’s works for pleasure. Ethically a member of London and Paris’ colonizers, Greene’s best writing still electrifies, perhaps partly because he was in the same line of fire as the victims he shared bread with. In fact, Greene hoped daily that he would escape from the dreadful conflicts he fictionalized via a body bag or an urn of ashes (see Sherry). In reading an author’s biography we have one window on the ethical dimensions of authority and print. If a print’s aesthetics are sometimes enduring, its ethical relationships are always mutable. Take the stylized logo of a running athlete: four limbs bent in a rotation of action. This dynamic icon has symbolized ‘good health’ in Hindu and Buddhist culture, from Madras to Tokyo, for thousands of years. The cross of bent limbs was borrowed for the militarized health programs of 1930s Germany, and, because of what was only a brief, recent, isolated yet monstrously horrific segment of its history in print, the bent-limbed swastika is now a vilified symbol in the West. The sign remains ‘impressed’ differently on traditional Eastern culture, and without the taint of Nazism. Dramatic prints are emotionally charged because, in depicting Homo sapiens in danger, or passionately in love, they elicit a hormonal reaction from the reader, the viewer, or the audience. The type of emotions triggered by a print vary across the whole gamut of human chemistry. A recent study of three genres of motion picture prints shows a marked differences in the hormonal responses of men compared to women when viewing a romance, an actioner, and a documentary (see Schultheiss, Wirth, and Stanton). Society is biochemically diverse in its engagement with printed culture, which raises questions about equality in the arts. Motion picture prints probably comprise around one third of internet traffic, in the form of stolen digitized movie files pirated across the globe via peer-to-peer file transfer networks (p2p), and burnt as DVD laser prints (BBC). There is also a US 40 billion dollar per annum legitimate commerce in DVD laser pressings (Grassl), which would suggest an US 80 billion per annum world total in legitimate laser disc print culture. The actively screen literate, or the ‘sliterati’ as I prefer to call them, research this world of motion picture prints via their peers, their internet information channels, their television programming, and their web forums. Most of this activity occurs outside the ambit of universities and schools. One large site of sliterate (screen literate) practice outside most schooling and official research is the net of online forums at imdb.com (International Movie Data Base). Imdb.com ‘prints’ about 25,000,000 top pages per month to client browsers. Hundreds of sliterati forums are located at imdb, including a forum for the Australian movie, Muriel’s Wedding (Hogan). Ten years after the release of Muriel’s Wedding, young people who are concerned with victimization and bullying still log on to http://us.imdb.com/title/tt0110598/board/> and put their thoughts into print: I still feel so bad for Muriel in the beginning of the movie, when the girls ‘dump’ her, and how much the poor girl cried and cried! Those girls were such biartches…I love how they got their comeuppance! bunniesormaybemidgets’s comment is typical of the current discussion. Muriel’s Wedding was a very popular film in its first cinema edition in Australia and elsewhere. About 30% of the entire over-14 Australian population went to see this photochemical polyester print in the cinemas on its first release. A decade on, the distributors printed a DVD laser disc edition. The story concerns Muriel (played by Toni Collette), the unemployed daughter of a corrupt, ‘police state’ politician. Muriel is bullied by her peers and she withdraws into a fantasy world, deluding herself that a white wedding will rescue her from the torments of her blighted life. Through theft and deceit (the modus operandi of her father) Muriel escapes to the entertainment industry and finds a ‘wicked’ girlfriend mentor. From a rebellious position of stubborn independence, Muriel plays out her fantasy. She gets her white wedding, before seeing both her father and her new married life as hollow shams which have goaded her abandoned mother to suicide. Redefining her life as a ‘game’ and assuming responsibility for her independence, Muriel turns her back on the mainstream, image-conscious, female gang of her oppressed youth. Muriel leaves the story, having rekindled her friendship with her rebel mentor. My methodological approach to viewing the laser disc print was to first make a more accessible, coded record of the entire movie. I was able to code and record the print in real time, using a new metalanguage (Watson, “Eyes”). The advantage of Coding is that ‘thinks’ the same way as film making, it does not sidetrack the analyst into prose. The Code splits the movie print into Vision Action [vision graphic elements, including text] (sound) The Coding splits the vision track into normal action and graphic elements, such as text, so this Coding is an ideal method for extracting all the text elements of a film in real time. After playing the film once, I had four and a half tightly packed pages of the coded story, including all its text elements in square brackets. Being a unique, indexed hard copy, the Coded copy allowed me immediate access to any point of the Muriel’s Wedding saga without having to search the DVD laser print. How are ‘print’ elements used in Muriel’s Wedding? Firstly, a rose-coloured monoprint of Muriel Heslop’s smiling face stares enigmatically from the plastic surface of the DVD picture disc. The print is a still photo captured from her smile as she walked down the aisle of her white wedding. In this print, Toni Collette is the Mona Lisa of Australian culture, except that fans of Muriel’s Wedding know the meaning of that smile is a magical combination of the actor’s art: the smile is both the flush of dreams come true and the frightening self deception that will kill her mother. Inserting and playing the disc, the text-dominant menu appears, and the film commences with the text-dominant opening titles. Text and titles confer a legitimacy on a work, whether it is a trade mark of the laser print owners, or the household names of stars. Text titles confer status relationships on both the presenters of the cultural artifact and the viewer who has entered into a legal license agreement with the owners of the movie. A title makes us comfortable, because the mind always seeks to name the unfamiliar, and a set of text titles does that job for us so that we can navigate the ‘tracks’ and settle into our engagement with the unfamiliar. The apparent ‘truth’ and ‘stability’ of printed text calms our fears and beguiles our uncertainties. Muriel attends the white wedding of a school bully bride, wearing a leopard print dress she has stolen. Muriel’s spotted wild animal print contrasts with the pure white handmade dress of the bride. In Muriel’s leopard textile print, we have the wild, rebellious, impoverished, inappropriate intrusion into the social ritual and fantasy of her high-status tormentor. An off-duty store detective recognizes the printed dress and calls the police. The police are themselves distinguished by their blue-and-white checked prints and other mechanically reproduced impressions of cultural symbols: in steel, brass, embroidery, leather and plastics. Muriel is driven in the police car past the stenciled town sign (‘Welcome To Porpoise Spit’ heads a paragraph of small print). She is delivered to her father, a politician who presides over the policing of his town. In a state where the judiciary, police and executive are hijacked by the same tyrant, Muriel’s father, Bill, pays off the police constables with a carton of legal drugs (beer) and Muriel must face her father’s wrath, which he proceeds to transfer to his detested wife. Like his daughter, the father also wears a spotted brown print costume, but his is a batik print from neighbouring Indonesia (incidentally, in a nation that takes the political status of its batik prints very seriously). Bill demands that Muriel find the receipt for the leopard print dress she claims she has purchased. The legitimate ownership of the object is enmeshed with a printed receipt, the printed evidence of trade. The law (and the paramilitary power behind the law) are legitimized, or contested, by the presence or absence of printed text. Muriel hides in her bedroom, surround by poster prints of the pop group ABBA. Torn-out prints of other people’s weddings adorn her mirror. Her face is embossed with the clown-like primary colours of the marionette as she lifts a bouquet to her chin and stares into the real time ‘print’ of her mirror image. Bill takes the opportunity of a business meeting with Japanese investors to feed his entire family at ‘Charlie Chan’’s restaurant. Muriel’s middle sister sloppily wears her father’s state election tee shirt, printed with the text: ‘Vote 1, Bill Heslop. You can’t stop progress.’ The text sets up two ironic gags that are paid off on the dialogue track: “He lost,’ we are told. ‘Progress’ turns out to be funding the concreting of a beach. Bill berates his daughter Muriel: she has no chance of becoming a printer’s apprentice and she has failed a typing course. Her dysfunction in printed text has been covered up by Bill: he has bribed the typing teacher to issue a printed diploma to his daughter. In the gambling saloon of the club, under the arrays of mechanically repeated cultural symbols lit above the poker machines (‘A’ for ace, ‘Q’ for queen, etc.), Bill’s secret girlfriend Diedre risks giving Muriel a cosmetics job. Another text icon in lights announces the surf nightclub ‘Breakers’. Tania, the newly married queen bitch who has made Muriel’s teenage years a living hell, breaks up with her husband, deciding to cash in his negotiable text documents – his Bali honeymoon tickets – and go on an island holiday with her girlfriends instead. Text documents are the enduring site of agreements between people and also the site of mutations to those agreements. Tania dumps Muriel, who sobs and sobs. Sobs are a mechanical, percussive reproduction impressed on the sound track. Returning home, we discover that Muriel’s older brother has failed a printed test and been rejected for police recruitment. There is a high incidence of print illiteracy in the Heslop family. Mrs Heslop (Jeannie Drynan), for instance, regularly has trouble at the post office. Muriel sees a chance to escape the oppression of her family by tricking her mother into giving her a blank cheque. Here is the confluence of the legitimacy of a bank’s printed negotiable document with the risk and freedom of a blank space for rebel Muriel’s handwriting. Unable to type, her handwriting has the power to steal every cent of her father’s savings. She leaves home and spends the family’s savings at an island resort. On the island, the text print-challenged Muriel dances to a recording (sound print) of ABBA, her hand gestures emphasizing her bewigged face, which is made up in an impression of her pop idol. Her imitation of her goddesses – the ABBA women, her only hope in a real world of people who hate or avoid her – is accompanied by her goddesses’ voices singing: ‘the mystery book on the shelf is always repeating itself.’ Before jpeg and gif image downloads, we had postcard prints and snail mail. Muriel sends a postcard to her family, lying about her ‘success’ in the cosmetics business. The printed missal is clutched by her father Bill (Bill Hunter), who proclaims about his daughter, ‘you can’t type but you really impress me’. Meanwhile, on Hibiscus Island, Muriel lies under a moonlit palm tree with her newly found mentor, ‘bad girl’ Ronda (Rachel Griffiths). In this critical scene, where foolish Muriel opens her heart’s yearnings to a confidante she can finally trust, the director and DP have chosen to shoot a flat, high contrast blue filtered image. The visual result is very much like the semiabstract Japanese Ukiyo-e woodblock prints by Utamaro. This Japanese printing style informed the rise of European modern painting (Monet, Van Gogh, Picasso, etc., were all important collectors and students of Ukiyo-e prints). The above print and text elements in Muriel’s Wedding take us 27 minutes into her story, as recorded on a single page of real-time handwritten Coding. Although not discussed here, the Coding recorded the complete film – a total of 106 minutes of text elements and main graphic elements – as four pages of Code. Referring to this Coding some weeks after it was made, I looked up the final code on page four: taxi [food of the sea] bq. Translation: a shop sign whizzes past in the film’s background, as Muriel and Ronda leave Porpoise Spit in a taxi. Over their heads the text ‘Food Of The Sea’ flashes. We are reminded that Muriel and Ronda are mermaids, fantastic creatures sprung from the brow of author PJ Hogan, and illuminated even today in the pantheon of women’s coming-of-age art works. That the movie is relevant ten years on is evidenced by the current usage of the Muriel’s Wedding online forum, an intersection of wider discussions by sliterate women on imdb.com who, like Muriel, are observers (and in some cases victims) of horrific pressure from ambitious female gangs and bullies. Text is always a minor element in a motion picture (unless it is a subtitled foreign film) and text usually whizzes by subliminally while viewing a film. By Coding the work for [text], all the text nuances made by the film makers come to light. While I have viewed Muriel’s Wedding on many occasions, it has only been in Coding it specifically for text that I have noticed that Muriel is a representative of that vast class of talented youth who are discriminated against by print (as in text) educators who cannot offer her a life-affirming identity in the English classroom. Severely depressed at school, and failing to type or get a printer’s apprenticeship, Muriel finds paid work (and hence, freedom, life, identity, independence) working in her audio visual printed medium of choice: a video store in a new city. Muriel found a sliterate admirer at the video store but she later dumped him for her fantasy man, before leaving him too. One of the points of conjecture on the imdb Muriel’s Wedding site is, did Muriel (in the unwritten future) get back together with admirer Brice Nobes? That we will never know. While a print forms a track that tells us where culture has been, a print cannot be the future, a print is never animate reality. At the end of any trail of prints, one must lift one’s head from the last impression, and negotiate satisfaction in the happening world.

While exploring the virtual world Second Life one day, I received a group message across the in-world communication system – “there’s a griefer on the beach. Stay away from the beach till we catch him.” There was no need to explain; everyone receiving the message knew what a griefer was and had a general idea of the kinds of things that could be happening. We’d all seen griefers at work before – someone monopolising the chat channel so no one else can communicate, people being “caged” at random, or even weapons fire causing so much “overhead” that all activity in the area slows to a crawl. These kinds of attacks are not limited to virtual worlds. Most people have experienced griefing in their everyday lives, which might best be defined as having fun at someone else’s expense. More commonly seen examples of this in the real world include teasing, bullying, and harassment; playground bullies have long made other children’s free time miserable. More destructive griefing includes arson and theft. Griefing activities happen in all kinds of games and virtual worlds. Griefers who laugh at new users and “yell” (so that all players can hear) that they stink, have followed new users of Disney’s tween-popular ToonTown. Griefers pose as friendly, helpful players who offer to show new users a path through difficult parts of a game, but then who abandon the new user in a spot where he or she does not have the skills to proceed. In World of Warcraft, a popular massively multiplayer online role playing game (MMORPG) created by Blizzard with more than seven million registered, if not active, users, griefers engage in what is known as corpse camping; they sit by a corpse, killing it over and over every time the player tries to get back into the game. The griefer gets a small number of experience points; the player being killed gets aggravated and has to wait out the griefing to play the game again (Warner & Raiter). Griefing in World of Warcraft was featured in an award nominated episode of the television program South Park, in which one character killed every other player he met. This paper considers different types of griefing, both in online games and virtual worlds, and then looks at the actions other players, those being griefed, take against griefers. A variety of examples from Second Life are considered because of the open-structure of the world and its developing nature. Definitions and Types Griefing in online environments such as video games and virtual worlds has been defined as “purposefully engaging in activities to disrupt the gaming experience of other players” (Mulligan & Patrovsky 250). The “purposeful” part of the definition means that accidental bumping and pushing, behaviours often exhibited by new users, are not griefing (Warner & Raiter). Rossingol defines a griefer as, “a player of malign intentions. They will hurt, humiliate and dishevel the average gamer through bending and breaking the rules of online games. ...They want glory, gain or just to partake in a malignant joy at the misfortune of others.” Davis, who maintains a gaming blog, describes Second Life as being populated by “those who build things and those who like to tear them down,” with the latter being the griefers who may be drawn to the unstructured anything-goes nature of the virtual world (qtd. in Girard). Definitions of griefing differ based on context. For instance, griefing has been examined in a variety of multi-player online games. These games often feature missions where players have to kill other players (PvP), behaviour that in other contexts such as virtual worlds would be considered griefing. Putting a monster on the trail of a player considered rude or unskilled might be a way to teach a lesson, but also an example of griefing (Taylor). Foo and Koivisto define griefing in MMORPGs as “play styles that disrupt another player’s gaming experience, usually with specific intention. When the act is not specifically intended to disrupt and yet the actor is the sole beneficiary, it is greed play, a subtle form of grief play” (11). Greed play usually involves actions that disrupt the game play of others but without technically breaking any game rules. A different way of looking at griefing is that it is a sign that the player understands the game or virtual world deeply enough to take advantage of ambiguities in the rules by changing the game to something new (Koster). Many games have a follow option; griefers pick a victim, stand near them, get as naked as possible, and then just follow them around without talking or explaining their actions (Walker). Another example is the memorial service in World of Warcraft for a player who died in real life. The service was interrupted by an attack from another clan; everyone at the memorial service was killed. It is not clear cut who the griefers actually were in this case – the mourners who chose to have their peaceful service in an area marked for player combat or the attackers following the rules for that area and working to earn points and progress in the game. In the case of the mourners, they were changing the rules of the game to suit them, to create something unique – a shared space to mourn a common friend. But they were definitely not playing by the rules. The attackers, considered griefers by many both in and outside of the game, did nothing that broke any rules of the game, though perhaps they broke rules of common decency (“World”); what they did does not fit into the definition of griefing, as much as do the actions of the mourners (Kotaku). Reshaping the game can be done to embed a new, sometimes political, message into the game. A group named Velvet Strike formed to protest US military action. They went into Counter Strike to bring a “message of peace, love and happiness to online shooters by any means necessary” (King). They placed spray painted graphics containing anti-war messages into the game; when confronted with people from other teams the Velvet Strike members refused to shoot (King). The group website contains “recipes” for non-violent game play. One “recipe” involved the Velvet Strike member hiding at the beginning of a mission and not moving for the rest of the game. The other players would shoot each other and then be forced to spend the rest of the game looking for the last survivor in order to get credit for the win. Similar behaviour has been tried inside the game America’s Army. Beginning March, 2006, deLappe, an artist who opposes the U.S. government’s involvement in Iraq, engaged in griefing behaviour by filling (spamming) the in-game text channel with the names of the people killed in the war; no one else can communicate on that channel. Even his character name, dead-in-Iraq, is an anti-war protest (deLappe). “I do not participate in the proscribed mayhem. Rather, I stand in position and type until I am killed. After death, I hover over my dead avatar’s body and continue to type. Upon being re-incarnated in the next round, I continue the cycle” (deLappe n.p.). What about these games and virtual worlds might lead people to even consider griefing? For one thing, they seem anonymous, which can lead to irresponsible behaviour. Players use fake names. Characters on the screen do not seem real. Another reason may be that rules can be broken in videogames and virtual worlds with few consequences, and in fact the premise of the game often seems to encourage such rule breaking. The rules are not always clearly laid out. Each game or world has a Terms of Service agreement that set out basic acceptable behaviour. Second Life defines griefing in terms of the Terms of Service that all users agree to when opening accounts. Abuse is when someone consciously and with malicious intent violates those terms. On top of that limited set of guidelines, each landowner in a virtual world such as Second Life can also set rules for their own property, from dress code, to use of weapons, to allowable conversation topics. To better understand griefing, it is necessary to consider the motivations of the people involved. Early work on categorising player types was completed by Bartle, who studied users of virtual worlds, specifically MUDs, and identified four player types: killers, achievers, socialisers, and explorers. Killers and achievers seem most relevant in a discussion about griefing. Killers enjoy using other players to get ahead. They want to do things to other people (not for or with others), and they get the most pleasure if they can act without the consent of the other player. Knowing about a game or a virtual world gives no power unless that knowledge can be used to gain some advantage over others and to enhance your standing in the game. Achievers want power and dominance in a game so they can do things to the game and master it. Griefing could help them feel a sense of power if they got people to do their will to stop the griefing behavior. Yee studied the motivations of people who play MMORPGs. He found that people who engage in griefing actually scored high in being motivated to play by both achieving and competition (“Facets”). Griefers often want attention. They may want to show off their scripting skills in the hope of earning respect among other coders and possibly be hired to program for others. But many players are motivated by a desire to compete and to win; these categories do not seem to be adequate for understanding the different types of griefing (Yee, “Faces of Grief”). The research on griefing in games has also suggested ways to categorise griefers in virtual worlds. Suler divides griefers into two types (qtd. in Becker). The first is those who grief in order to make trouble for authority figures, including the people who create the worlds. A few of the more spectacular griefing incidents seem designed to cause trouble for Linden Lab, the creators of Second Life. Groups attacked the servers that run Second Life, known as the grid, in October of 2005; this became known as the “gray goo attack” (Second Life; Wallace). Servers were flooded with objects and Second Life had to be taken off line to be restored from backups. More organised groups, such as the W-hats, the SL Liberation Army, and Patriotic Nigas engage in more large scale and public griefing. Some groups hope to draw attention to the group’s goals. The SL Liberation Army wants Linden Lab to open up the governance of the virtual world so that users can vote on changes and policies being implemented and limit corporate movement into Second Life (MarketingVox). Patriotic Nigas, with about 35 active members, want to slow the entry of corporations into Second Life (Cabron, “Who are Second Life’s”). One often discussed griefer attack in Second Life included a flood of pink flying penises directed against land owner and the first person to have made a profit of more than one million United States dollars in a virtual world, Anshe Chung, during a well-publicised and attended interview in world with technology news outlet CNET (Walsh, “Second Life Millionaire” ). The second type proposed by Suler is the griefer who wants to hurt and victimise others (qtd. in Becker). Individual players often go naked into PG-rated areas to cause trouble. Weapons are used in areas where weapons are banned. Second Life publishes a police blotter, which lists examples of minor griefing and assigned punishment, including incidents of disturbing the peace and violating community standards for which warnings and short bans have been issued. These are the actions of individuals for the most part, as were the people who exploited security holes to enter the property uninvited during the grand opening of Endemol’s Big Brother island in Second Life; guests to the opening were firebombed and caged. One of the griefers explained her involvement: Well I’m from The Netherlands, and as you might know the tv concept of big brother was invented here, and it was in all the newspapers in Holland. So I thought It would be this huge event with lots of media. Then I kinda got the idea ‘hey I could ruin this and it might make the newspaper or tv. So that’s what set me off, lol. (qtd. in Sklar) Some groups do grief just to annoy. The Patriotic Nigas claim to have attacked the John Edwards headquarters inside SL wearing Bush ‘08 buttons (Cabron, “John Edwards Attackers”), but it was not a political attack. The group’s founder, Mudkips Acronym (the name of his avatar in SL) said, “I’m currently rooting for Obama, but that doesn’t mean we won’t raid him or anything. We’ll hit anyone if it’s funny, and if the guy I want to be president in 2008’s campaign provides the lulz, we’ll certainly not cross him off our list” (qtd. in Cabron, “John Edwards Attackers”). If they disrupt a high profile event or site, the attack will be covered by media that can amplify the thrill of the attack, enhance their reputation among other griefers, and add to their enjoyment of the griefing. Part of the definition of griefing is that the griefer enjoys causing other players pain and disrupting their game. One resident posted on the SL blog, “Griefers, for the most part, have no other agenda other than the thrill of sneaking one past and causing a big noise. Until a spokesperson comes forward with a manifesto, we can safely assume that this is the work of the “Jackass” generation, out to disrupt things to show that they can“ (Scarborough). Usually to have fun, griefers go after individuals, rather than the owners and administrators of the virtual world and so fit into Suler’s second type of griefing. These griefers enjoy seeing others get angry and frustrated. As one griefer said: Understanding the griefer mindset begins with this: We don’t take the game seriously at all. It continues with this: It’s fun because you react. Lastly: We do it because we’re jerks and like to laugh at you. I am the fly that kamikazes into your soup. I am the reason you can’t have nice things … . If I make you cry, you’ve made my day. (Drake) They have fun by making the other players mad. “Causing grief is the name of his game. His objective is simple: Make life hell for anyone unlucky enough to be playing with him. He’s a griefer. A griefer is a player bent on purposely frustrating others during a multiplayer game” (G4). “I’m a griefer. It’s what I do,” the griefer says. “And, man, people get so pissed off. It’s great” (G4). Taking Action against Griefers Understanding griefing from the griefer point of view leads us to examine the actions of those being griefed. Suler suggests several pairs of opposing actions that can be taken against griefers, based on his experience in an early social environment called Palace. Many of the steps still being used fit into these types. He first describes preventative versus remedial action. Preventative steps include design features to minimise griefing. The Second Life interface includes the ability to build 3D models and to create software; it also includes a menu for land owners to block those features at will, a design feature that helps prevent much griefing. Remedial actions are those taken by the administrators to deal with the effects of griefing; Linden Lab administrators can shut down whole islands to keep griefer activities from spreading to nearby islands. The second pair is interpersonal versus technical; interpersonal steps involve talking to the griefers to get them to stop ruining the game for others, while technical steps prevent griefers from re-entering the world. The elven community in Second Life strongly supports interpersonal steps; they have a category of members in their community known as guardians who receive special training in how to talk to people bent on destroying the peacefulness of the community or disturbing an event. The creators of Camp Darfur on Better World island also created a force of supporters to fend off griefer attacks after the island was destroyed twice in a week in 2006 (Kenzo). Linden Lab also makes use of technical methods; they cancel accounts so known griefers can not reenter. There were even reports that they had created a prison island where griefers whose antics were not bad enough to be totally banned would be sent via a one-way teleporter (Walsh, “Hidden Virtual World Prison”). Some users of Second Life favour technical steps; they believe that new users should be held a fixed amount of time on the Orientation island which would stop banned users from coming back into the world immediately. The third is to create tools for average users or super users (administrators); both involve software features, some of which are available to all users to help them make the game good for them while others are available only to people with administrator privileges. Average users who own land have a variety of tools available to limit griefing behaviour on their own property. In Second Life, the land owner is often blamed because he or she did not use the tools provided to landowners by Linden Lab; they can ban individual users, remove users from the land, mute their conversation, return items left on the property, and prevent people from building or running scripts. As one landowner said, “With the newbies coming in there, I’ve seen their properties just littered with crap because they don’t know protective measures you need to take as far as understanding land control and access rights” (qtd. in Girard). Super users, those who work for Linden Lab, can remove a player from the game for a various lengths of time based on their behaviour patterns. Responses to griefers can also be examined as either individual or joint actions. Individual actions include those that land owners can take against individual griefers. Individual users, regardless of account type, can file abuse reports against other individuals; Linden Lab investigates these reports and takes appropriate action. Quick and consistent reporting of all griefing, no matter how small, is advocated by most game companies and user groups as fairly successful. Strangely, some types of joint actions have been not so successful. Landowners have tried to form the Second Life Anti-Griefing Guild, but it folded because of lack of involvement. Groups providing security services have formed; many event organisers use this kind of service. (Hoffman). More successful efforts have included the creation of software, such as SLBanLink.com, Karma, and TrustNet that read lists of banned users into the banned list on all participating property. A last category of actions to be taken against griefers, and a category used by most residents of virtual worlds, is to leave them alone—to ignore them, to tolerate their actions. The thinking is that, as with many bullies in real life, griefers want attention; when deprived of that, they will move on to find other amusements. Yelling and screaming at griefers just reinforces their bad behaviour. Users simply teleport to other locations or log off. They warn others of the griefing behaviour using the various in-world communication tools so they too can stay away from the griefers. Most of the actions described above are not useful against griefers for whom a bad reputation is part of their credibility in the griefer community. The users of Second Life who staged the Gray Goo denial of service attack in October, 2005 fit into that category. They did nothing to hide the fact that they wanted to cause massive trouble; they named the self-replicating object that they created Grief Spawn and discussed ways to bring down the world on griefer forums (Wallace) Conclusion The most effective griefing usually involves an individual or small group who are only looking to have fun at someone else’s expense. It’s a small goal, and as long as there are any other users, it is easy to obtain the desired effect. In fact, as word spreads of the griefing and users feel compelled to change their behaviour to stave off future griefer attacks, the griefers have fun and achieve their goal. The key point here is that everyone has the same goal – have fun. Unfortunately, for one group – the griefers – achieving their goal precludes other users from reaching theirs. Political griefers are less successful in achieving their goals. Political creative play as griefing, like other kinds of griefing, is not particularly effective, which is another aspect of griefing as error. Other players react with frustration and violence to the actions of griefers such as deLappe and Velvet-Strike. If griefing activity makes people upset, they are less open to considering the political or economic motives of the griefers. Some complaints are relatively mild; “I’m all for creative protest and what not, but this is stupid. It’s not meaningful art or speaking out or anything of the type, its just annoying people who are never going to change their minds about how awesome they think war is” (Borkingchikapa). Others are more negative: “Somebody really needs to go find where that asshole lives and beat the shit out of him. Yeah, it’s a free country and he can legally pull this crap, but that same freedom extends to some patriot kicking the living shit out of him” (Reynolds). In this type of griefing no one’s goals for using the game are satisfied. The regular users can not have fun, but neither do they seem to be open to or accepting of the political griefer’s message. This pattern of success and failure may explain why there are so many examples of griefing to disrupt rather then the politically motivated kind. It may also suggest why efforts to curb griefing have been so ineffective in the past. Griefers who seek to disrupt for fun would see it as a personal triumph if others organised against them. Even if they found themselves banned from one area, they could quickly move somewhere else to have their fun since whom or where they harass does not really matter. Perhaps not all griefing is in error, rather, only those griefing activities motivated by any other goal than have fun. People invest their time and energy in creating their characters and developing skills. The behaviour of people in these virtual environments has a definite bearing on the real world. And perhaps that explains why people in these virtual worlds react so strongly to the behaviour. So, remember, stay off the beach until they catch the griefers, and if you want to make up the game as you go along, be ready for the other players to point at you and say “Bad, Bad Avatar.” References Bartle, Richard. “Players Who Suit MUDs.” Journal of MUD Research 1.1 (June 1996). 10 Sep. 2007 http://www.mud.co.uk/richard/hcds.htm>.
