kmth price sealed-bid auctions with general independent values and equilibrium linear mark-ups

A generalised bidding model is developed to calculate a bidder’s expected profit and auctioners expected revenue/payment for both a General Independent Value and Independent Private Value (IPV) kmth price sealed-bid auction (where the mth bidder wins at the kth bid payment) using a linear (affine) mark-up function. The Common Value (CV) assumption, and highbid and lowbid symmetric and asymmetric First Price Auctions and Second Price Auctions are included as special cases. The optimal n bidder symmetric analytical results are then provided for the uniform IPV and CV models in equilibrium. Final comments concern implications, the assumptions involved and prospects for further research.

Mark Shorter : Dry Gulch

This is a catalogue essay for Mark Shorter's exhibition "Dry Gulch" held at Boxcopy, Brisbane, in 2014. "Dry Gulch is a durational performance and installation in which the artist, Mark Shorter, occupies the pitch-­‐black gallery space for the opening hours of the exhibition. While drawing on the vocabulary of 1970s conceptual performance art (think Vito Acconci, Chris Burden, Marina Abramovic et al.), it is also an exhibition specifically of its time and its place. It probes and, at times, illuminates (pun intended) some of the dark corners of subjective experiences in a contemporary context typically swamped by distractions and saturated with templates for self-­‐actualisation...."

Breakfast at Tiffany's': eBay Inc., trade mark law, and counterfeiting

In an exploration of intellectual property and fashion, this article examines the question of the intermediary liability of online auction-houses for counterfeiting. In the United States, the illustrious jewellery store, Tiffany & Co, brought a legal action against eBay Inc, alleging direct trademark infringement, contributory trademark infringement, false advertising, unfair competition and trademark dilution. The luxury store depicted the online auction-house as a pirate bazaar, a flea-market and a haven for counterfeiting. During epic litigation, eBay Inc successfully defended itself against these allegations in a United States District Court and the United States Court of Appeals for the Second Circuit. Tiffany & Co made a desperate, unsuccessful effort to appeal the matter to the Supreme Court of the United States. The matter featured a number of interventions from amicus curiae — Tiffany was supported by Coty, the Fashion Designer's Guild, and the International Anticounterfeiting Coalition, while eBay was defended by publicly-spirited civil society groups such as Electronic Frontier Foundation, Public Citizen, and Public Knowledge as well as Yahoo!, Google Inc, Amazon.com, and associations representing telecommunications carriers and internet service providers. The litigation in the United States can be counterpointed with the fusillade of legal action against eBay in the European Union. In contrast to Tiffany & Co, Louis Vuitton triumphed over eBay in the French courts — claiming its victory as vindication of the need to protect the commercial interests and cultural heritage of France. However, eBay has fared somewhat better in a dispute with L’Oréal in Great Britain and the European Court of Justice. It is argued that, in a time of flux and uncertainty, Australia should follow the position of the United States courts in Tiffany & Co v eBay Inc. The final part examines the ramifications of this litigation over online auction-houses for trade mark law reform and consumer rights; parallel disputes over intermediary liability and safe harbours in the field of copyright law and the Anti-Counterfeiting Trade Agreement 2010. The conclusion calls for a revision of trade mark law, animated by a respect for consumers’ rights and interests in the electronic marketplace.

The Black Label: trade mark dilution, culture jamming, and the no logo movement

This article considers the ongoing debate over the appropriation of well-known and famous trade marks by the No Logo Movement for the purposes of political and social critique. It focuses upon one sensational piece of litigation in South Africa, Laugh It Off Promotions v. South African Breweries International (Finance) B.V. t/a Sabmark International. In this case, a group called Laugh It Off Promotions subjected the trade marks of the manufacturers of Carling Beer were subjected to parody, social satire, and culture jamming. The beer slogan “Black Label” was turned into a T-Shirt entitled “Black Labour/ White Guilt”. In the ensuing litigation, the High Court of South Africa and the Supreme Court of Appeal were of the opinion that the appropriation of the mark was a case of hate speech. However, the Constitutional Court of South Africa disagreed, finding that the parodies of a well-known, famous trade mark did not constitute trade mark dilution. Moseneke J observed that there was a lack of evidence of economic or material harm; and Sachs J held that there is a need to provide latitude for parody, laughter, and freedom of expression. The decision of the Constitutional Court of South Africa provides some important insights into the nature of trade mark dilution, the role of parody and satire, and the relevance of constitutional protections of freedom of speech and freedom of expression. Arguably, the ruling will be of help in the reformation of trade mark dilution law in other jurisdictions – such as the United States. The decision in Laugh It Off Promotions v. South African Breweries International demonstrates that trade mark law should not be immune from careful constitutional scrutiny.

No logo: Brand bullies, trade mark law, and the Trans-Pacific Partnership

The Trans-Pacific Partnership is a sweeping trade agreement, spanning the Pacific Rim, and covering an array of topics, including intellectual property. There has been much analysis of the recently leaked intellectual property chapter of the Trans-Pacific Partnership by WikiLeaks. Julian Assange, WikiLeaks’ Editor-in-Chief, observed “The selective secrecy surrounding the TPP negotiations, which has let in a few cashed-up megacorps but excluded everyone else, reveals a telling fear of public scrutiny. By publishing this text we allow the public to engage in issues that will have such a fundamental impact on their lives.” Critical attention has focused upon the lack of transparency surrounding the agreement, copyright law and the digital economy; patent law, pharmaceutical drugs, and data protection; and the criminal procedures and penalties for trade secrets. The topic of trade mark law and related rights, such as internet domain names and geographical indications, deserves greater analysis.

A comparison of mark-recapture distance-sampling methods applied to aerial surveys of eastern grey kangaroos

Aerial surveys of kangaroos (Macropus spp.) in Queensland are used to make economically important judgements on the levels of viable commercial harvest. Previous analysis methods for aerial kangaroo surveys have used both mark-recapture methodologies and conventional distance-sampling analyses. Conventional distance sampling has the disadvantage that detection is assumed to be perfect on the transect line, while mark-recapture methods are notoriously sensitive to problems with unmodelled heterogeneity in capture probabilities. We introduce three methodologies for combining together mark-recapture and distance-sampling data, aimed at exploiting the strengths of both methodologies and overcoming the weaknesses. Of these methods, two are based on the assumption of full independence between observers in the mark-recapture component, and this appears to introduce more bias in density estimation than it resolves through allowing uncertain trackline detection. Both of these methods give lower density estimates than conventional distance sampling, indicating a clear failure of the independence assumption. The third method, termed point independence, appears to perform very well, giving credible density estimates and good properties in terms of goodness-of-fit and percentage coefficient of variation. Estimated densities of eastern grey kangaroos range from 21 to 36 individuals km-2, with estimated coefficients of variation between 11% and 14% and estimated trackline detection probabilities primarily between 0.7 and 0.9.

ShadowBoxer and LocusEater: programs to optimise experimental design and multiplexing strategies for genetic mark-recapture

Genetic mark–recapture requires efficient methods of uniquely identifying individuals. 'Shadows' (individuals with the same genotype at the selected loci) become more likely with increasing sample size, and bias harvest rate estimates. Finding loci is costly, but better loci reduce analysis costs and improve power. Optimal microsatellite panels minimize shadows, but panel design is a complex optimization process. locuseater and shadowboxer permit power and cost analysis of this process and automate some aspects, by simulating the entire experiment from panel design to harvest rate estimation.

Assessment of the underreporting rate of death cause data in Shandong province using capture-mark-recapture method [应用捕获再捕获方法评估山东省死因登记漏报率水平]

To evaluate the underreporting rate of death -cause data in Shandong province during 2012 to 2013 by capture -mark -recapture method and to provide the base for health strategy. Methods All counties were divided into 5 stratifications according the death rates of 2012, and 14 counties were selected, then 3 towns or streets were selected in each country, 10 villages or neighborhood committees were selected in each town （street）. The death data collected from security bureau and civil affairs bureau were compared with the reporting death data from the National Cause of Death Surveillance, and the underreporting rate was calculated. Results In present study, 6 929 death cases were collected, it was found that 1 556 cases were underreported. The death cases estimated by CMR method were 6 227 cases （95%CI: 7 593-7 651）, and the average underreporting rate was 23.15%. There were significantly differences between different stratifications （P<0.01）. The underreporting rate in 0-4 years old group was 56.93%, the male underreporting rate was 22.31% and the female underreporting rate was 24.09%. There was no significant difference between male and female groups （P>0.05）. Conclusion There is an obvious underreport in the cause of death surveillance of Shandong province, and the underreporting rates are different among the 5 stratifications. The underreporting rate is higher in 0-4 years old group, and the investigation of the death cause surveillance for young residents is not perfect in some countries. The investigation quality of the death cause surveillance should be improved, increasing the integrity of the report data and adjusting the mortalities in different stratifications for obtaining a accurate mortality in Shandong province.

Development of cattle production extension materials for use in destination mark

To collate support and extension materials to ensure the recipients of Australian cattle have, at least, a minimum understanding of animal husbandry. As the number of destination markets increases, the need will also increase to produce similar material relevant and locally sensitive for these new markets.

Mechanism to synthesize a `moving optical mark' at solid-ambient interface for the estimation of thermal diffusivity of solid

supporting unsteady heat flow with its ambient-humidity; invokes phase transformation of water-vapour molecule and synthesize a `moving optical-mark' at sample-ambient-interface. Under tailored condition, optical-mark exhibits a characteristic macro-scale translatory motion governed by thermal diffusivity of solid. For various step-temperature inputs via cooling, position-dependent velocities of moving optical-mark are measured at a fixed distance. A new approach is proposed. `Product of velocity of optical-mark and distance' versus `non-dimensional velocity' is plotted. The slope reveals thermal diffusivity of solid at ambient-temperature; preliminary results obtained for Quartz-glass is closely matching with literature. (C) 2016 Author(s).

Design of a Recreational Fishing Survey and Mark-Recapture Study for the Blue Crab, Callinectes sapidus, in Chesapeake Bay

The development of bay wide estimates of recreational harvest has been identified as a high priority by the Chesapeake Bay Scientific Advisory Committee (CBSAC) and by the Chesapeake Bay Program as reflected in the Chesapeake Bay Blue Crab Fishery Management Plan (Chesapeake Bay Program 1996). In addition, the BiState Blue Crab Commission (BBCAC), formed in 1996 by mandate from the legislatures of Maryland and Virginia to advise on crab management, has also recognized the importance of estimating the levels and trends in catches in the recreational fishery. Recently, the BBCAC has adopted limit and target biological reference points. These analyses have been predicated on assumptions regarding the relative magnitude of the recreational and commercial catch. The reference points depend on determination of the total number of crabs removed from the population. In essence, the number removed by the various fishery sectors, represents a minimum estimate of the population size. If a major fishery sector is not represented, the total population will be accordingly underestimated. If the relative contribution of the unrepresented sector is constant over time and harvests the same components of the population as the other sectors, it may be argued that the population estimate derived from the other sectors is biased but still adequately represents trends in population size over time. If either of the two constraints mentioned above is not met, the validity of relative trends over time is suspect. With the recent increases in the human population in the Chesapeake Bay watershed, there is reason to be concerned that the recreational catch may not have been a constant proportion of the total harvest over time. It is important to assess the catch characteristics and the magnitude of the recreational fishery to evaluate this potential bias. (PDF contains 70 pages)

Coma measurement by use of an alternating phase-shifting mask mark with a specific phase width

The correlation between the coma sensitivity of the alternating phase-shifting mask (Alt-PSM) mark and the mark's structure is studied based on the Hopkins theory of partially coherent imaging and positive resist optical lithography (PROLITH) simulation. It is found that an optimized Alt-PSM mark with its phase width being two-thirds its pitch has a higher sensitivity to coma than Alt-PSM marks with the same pitch and the different phase widths. The pitch of the Alt-PSM mark is also optimized by PROLITH simulation, and the structure of p - 1.92 lambda/NA and pw = 2p/3 proves to be with the highest sensitivity. The optimized Alt-PSM mark is used as a measurement mark to retrieve coma aberration from the projection optics in lithographic tools. In comparison with an ordinary Alt-PSM mark with its phase width being a half its pitch, the measurement accuracies of Z(7) and Z(14) apparently increase. (C) 2009 Optical Society of America
