Embracing humanity in the face of death: Why do existential concerns moderate ingroup humanization?

People humanize their ingroup to address existential concerns about their mortality, but the reasons why they do so remain ambiguous. One explanation is that people humanize their ingroup to bolster their social identity in the face of their mortality. Alternatively, people might be motivated to see their ingroup as more uniquely human (UH) to distance themselves from their corporeal “animal” nature. These explanations were tested in Australia, where social identity is tied less to UH and more to human nature (HN) which does not distinguish humans from animals. Australians attributed more HN traits to the ingroup when mortality was salient, while the attribution of UH traits remained unchanged. This indicates that the mortality-buffering function of ingroup humanization lies in reinforcing the humanness of our social identity, rather than just distancing ourselves from our animal nature. Implications for (de)humanization in intergroup relations are discussed.

Using a free online questionnaire to determine the skills, competencies and knowledge required to work in a digital library environment in Australia

This paper discusses the data collection technique used to determine the skills and knowledge required of academic librarians working in a digital library environment in Australia. The research was undertaken as part of the researcher’s master’s thesis conducted at Tallinn University. The data collection instrument used was a freely available online survey tool, and its advantages and disadvantages are discussed in terms of the desired outcomes and circumstances surrounding the thesis project. Decisions regarding the design of the questionnaire are also discussed.

Rapid detection of TNT in aqueous media by selective label free surface enhanced Raman spectroscopy

We report rapid and ultra-sensitive detection system for 2,4,6-trinitrotoluene (TNT) using unmodified gold nanoparticles and surface-enhanced Raman spectroscopy (SERS). First, Meisenheimer complex has been formed in aqueous solution between TNT and cysteamine in less than 15 min of mixing. The complex formation is confirmed by the development of a pink colour and a new UV–vis absorption band around 520 nm. Second, the developed Meisenheimer complex is spontaneously self-assembled onto unmodified gold nanoparticles through a stable Au–S bond between the cysteamine moiety and the gold surface. The developed mono layer of cysteamine-TNT is then screened by SERS to detect and quantify TNT. Our experimental results demonstrate that the SERS-based assay provide an ultra-sensitive approach for the detection of TNT down to 22.7 ng/L. The unambiguous fingerprint identification of TNT by SERS represents a key advantage for our proposed method. The new method provides high selectivity towards TNT over 2,4 DNT and picric acid. Therefore it satisfies the practical requirements for the rapid screening of TNT in real life samples where the interim 24-h average allowable concentration of TNT in waste water is 0.04 mg/L.

Two-dimensional bow and stern flows in a finite-depth fluid with constant vorticity

This thesis is concerned with two-dimensional free surface flows past semi-infinite surface-piercing bodies in a fluid of finite-depth. Throughout the study, it is assumed that the fluid in question is incompressible, and that the effects of viscosity and surface tension are negligible. The problems considered are physically important, since they can be used to model the flow of water near the bow or stern of a wide, blunt ship. Alternatively, the solutions can be interpreted as describing the flow into, or out of, a horizontal slot. In the past, all research conducted on this topic has been dedicated to the situation where the flow is irrotational. The results from such studies are extended here, by allowing the fluid to have constant vorticity throughout the flow domain. In addition, new results for irrotational flow are also presented. When studying the flow of a fluid past a surface-piercing body, it is important to stipulate in advance the nature of the free surface as it intersects the body. Three different possibilities are considered in this thesis. In the first of these possibilities, it is assumed that the free surface rises up and meets the body at a stagnation point. For this configuration, the nonlinear problem is solved numerically with the use of a boundary integral method in the physical plane. Here the semi-infinite body is assumed to be rectangular in shape, with a rounded corner. Supercritical solutions which satisfy the radiation condition are found for various values of the Froude number and the dimensionless vorticity. Subcritical solutions are also found; however these solutions violate the radiation condition and are characterised by a train of waves upstream. In the limit that the height of the body above the horizontal bottom vanishes, the flow approaches that due to a submerged line sink in a $90^\circ$ corner. This limiting problem is also examined as a special case. The second configuration considered in this thesis involves the free surface attaching smoothly to the front face of the rectangular shaped body. For this configuration, nonlinear solutions are computed using a similar numerical scheme to that used in the stagnant attachment case. It is found that these solution exist for all supercritical Froude numbers. The related problem of the cusp-like flow due to a submerged sink in a corner is also considered. Finally, the flow of a fluid emerging from beneath a semi-infinite flat plate is examined. Here the free surface is assumed to detach from the trailing edge of the plate horizontally. A linear problem is formulated under the assumption that the elevation of the plate is close to the undisturbed free surface level. This problem is solved exactly using the Wiener-Hopf technique, and subcritical solutions are found which are characterised by a train of sinusoidal waves in the far field. The nonlinear problem is also considered. Exact relations between certain parameters for supercritical flow are derived using conservation of mass and momentum arguments, and these are confirmed numerically. Nonlinear subcritical solutions are computed, and the results are compared to those predicted by the linear theory.

Place recognition with ConvNet landmarks: Viewpoint-robust, condition-robust, training-free

Place recognition has long been an incompletely solved problem in that all approaches involve significant compromises. Current methods address many but never all of the critical challenges of place recognition – viewpoint-invariance, condition-invariance and minimizing training requirements. Here we present an approach that adapts state-of-the-art object proposal techniques to identify potential landmarks within an image for place recognition. We use the astonishing power of convolutional neural network features to identify matching landmark proposals between images to perform place recognition over extreme appearance and viewpoint variations. Our system does not require any form of training, all components are generic enough to be used off-the-shelf. We present a range of challenging experiments in varied viewpoint and environmental conditions. We demonstrate superior performance to current state-of-the- art techniques. Furthermore, by building on existing and widely used recognition frameworks, this approach provides a highly compatible place recognition system with the potential for easy integration of other techniques such as object detection and semantic scene interpretation.

Reproducible and label-free biosensor for the selective extraction and rapid detection of proteins in biological fluids

Erythropoietin (EPO), a glycoprotein hormone of ∼34 kDa, is an important hematopoietic growth factor, mainly produced in the kidney and controls the number of red blood cells circulating in the blood stream. Sensitive and rapid recombinant human EPO (rHuEPO) detection tools that improve on the current laborious EPO detection techniques are in high demand for both clinical and sports industry. A sensitive aptamer-functionalized biosensor (aptasensor) has been developed by controlled growth of gold nanostructures (AuNS) over a gold substrate (pAu/AuNS). The aptasensor selectively binds to rHuEPO and, therefore, was used to extract and detect the drug from horse plasma by surface enhanced Raman spectroscopy (SERS). Due to the nanogap separation between the nanostructures, the high population and distribution of hot spots on the pAu/AuNS substrate surface, strong signal enhancement was acquired. By using wide area illumination (WAI) setting for the Raman detection, a low RSD of 4.92% over 150 SERS measurements was achieved. The significant reproducibility of the new biosensor addresses the serious problem of SERS signal inconsistency that hampers the use of the technique in the field. The WAI setting is compatible with handheld Raman devices. Therefore, the new aptasensor can be used for the selective extraction of rHuEPO from biological fluids and subsequently screened with handheld Raman spectrometer for SERS based in-field protein detection.

Free Sherlock: The copyright battle of Baker Street

Sherlock Holmes faces his greatest challenge – since his fight to the death with Professor James Moriarty at Reichenbach Falls. Who owns Sherlock Holmes, the world’s greatest detective? Is it the estate of Sir Arthur Conan Doyle? Or the mysterious socialite Andrea Plunket? Or does Sherlock Holmes belong to the public? This is the question currently being debated in copyright litigation in the United States courts, raising larger questions about copyright law and the public domain, the ownership of literary characters, and the role of sequels, adaptations, and mash-ups.

From Kafka to KAFTA: Intellectual property, and the Korea-Australia free trade agreement

This paper provides a critical examination of the intellectual property sections of the Korea-Australia Free Trade Agreement 2014. Chapter 13 of the Korea-Australia Free Trade Agreement 2014 deals with the subject of intellectual property law. The Chapter covers such topics as the purposes and objectives of intellectual property law; copyright law; trade mark law; patent law; and intellectual property enforcement. The Joint Standing Committee on Treaties in the Australian Parliament highlighted the controversy surrounding this chapter of the agreement: The intellectual property rights chapter of KAFTA has drawn considerable attention from academics and stakeholders regarding the proposed need for changes to Australian intellectual property law and the inclusion of intellectual property in the definition of investment with regard to the investor-state dispute mechanism. Other concerns raised with the Committee include the prescriptive nature of the chapter, the lack of recognition of the broader public interests of intellectual property rights, and possible changes to fair use provisions. Article 13.1.1 of the Korea-Australia Free Trade Agreement 2014 provides that: ‘Each Party recognises the importance of adequate and effective protection of intellectual property rights, while ensuring that measures to enforce those rights do not themselves become barriers to legitimate trade.’ This is an unsatisfactory description of the objectives and purposes of intellectual property law in both Australia and Korea. There is a failure to properly consider the range of public purposes served by intellectual property law – such as providing for access to knowledge, promoting competition and innovation, protecting consumer rights, and allowing for the protection of public health, food security, and the environment. Such a statement of principles and objectives detracts from the declaration in the TRIPS Agreement 1994 of the public interest objectives to be served by intellectual property. Chapter 11 of the Korea-Australia Free Trade Agreement 2014 is an investment chapter, with an investor-state dispute settlement regime. This chapter is highly controversial – given the international debate over investor-state dispute settlement; the Australian context for the debate; and the text of the Korea-Australia Free Trade Agreement 2014. In April 2014, the United Nations Conference on Trade and Development (UNCTAD) released a report on Recent Developments in Investor-State Dispute Settlement. The overall figures are staggering. UNCTAD reports a significant growth in investment-state dispute settlement, across a wide array of different fields of public regulation. Given the broad definition of investment, intellectual property owners will be able to use the investor-state dispute settlement regime in the Korea-Australia Free Trade Agreement 2014. This will have significant implications for all the various disciplines of intellectual property – including copyright law, trade mark law, and patent law.

Robbery under arms: Copyright law and the Australia-United States free trade agreement

TThis article considers the radical, sweeping changes to Australian copyright law wrought by the Australia–United States Free Trade Agreement 2004 (AUSFTA). It contends that the agreement will result in a “piracy of the public domain”. Under this new regime, copyright owners will be able to obtain greater monopoly profits at the expense of Australian consumers, libraries and research institutions, as well as intermediaries, such as Internet service providers. Part One observes that the copyright term extension in Australia to life of the author plus 70 years for works will have a negative economic and cultural impact — with Australia’s net royalty payments estimated to be up to $88 million higher per year. Part Two argues that the adoption of stronger protection of technological protection measures modelled upon the Digital Millennium Copyright Act 1998 (U.S.) will override domestic policy–making processes, such as the Phillips Fox Digital Agenda Review, and judicial pronouncements such as the Stevens v Sony litigation. Part Three questions whether the new safe harbours protection for Internet service providers will adversely affect the sale of Telstra. This article concludes that there is a need for judicial restraint in interpreting the AUSFTA. There is an urgent call for the Federal Government to pass ameliorating reforms — such as an open–ended defence of fair use and a mechanism for orphan works. There is a need for caution in negotiating future bilateral trade agreements — lest the multinational system for the protection of copyright law be undermined.

From ‘free’ to fee: Acceptability of airline ancillary fees and the effects on customer behavior

Businesses in various consumer service industries have begun to unbundle their service offerings by introducing numerous fees for products and services that were previously provided as “free.” Anecdotal evidence in the media indicates that these fees cause widespread public displeasure, frustration, and outrage. This paper develops a framework of fee acceptability, negative emotions, and dysfunctional customer behavior, which is tested using data from the airline industry. Findings identify the strongest effects on betrayal in the case of baggage fees, followed by charges for comfort. Also, betrayal has a direct effect on complaining, whereas anger mediates the relationship between betrayal and negative word of mouth.

The reach and rationale for community health fairs

Latinos living in the USA account for one third of the uninsured population and face numerous cultural, linguistic, and financial barriers to accessing healthcare services. Community health fairs have developed to address the unmet need for no- and low-cost services that target prevention and education among underserved communities. The current research describes an ongoing effort in a community in Southern California and examines the barriers to health care among participants registering to receive free breast health screenings, one of the major services offered at a 2010 health fair. A total of 186 adult Latina women completed a brief questionnaire assessing their healthcare utilization and self-reported barriers to engaging in preventive and screening services. Approximately two thirds of the participants reported never receiving or having more than 2 years passing since receiving a preventive health check-up. Participants identified cost (64.5 %) and knowledge of locations for services (52.3 %) as the primary barriers to engaging in routine healthcare services. Engaging with health professionals represents a leading way in which adults obtain health information; health fairs offering cancer health screenings represent a culturally appropriate venue for increased cancer health equity. Implications of the current research for future health fairs and their role in community cancer education are discussed.

ITO-free top emitting organic light emitting diodes with enhanced light out-coupling

Bottom emitting organic light emitting diodes (OLEDs) can suffer from lower external quantum efficiencies (EQE) due to inefficient out-coupling of the generated light. Herein, it is demonstrated that the current efficiency and EQE of red, yellow, and blue fluorescent single layer polymer OLEDs is significantly enhanced when a MoOx(5 nm)/Ag(10 nm)/MoOx(40 nm) stack is used as the transparent anode in a top emitting OLED structure. A maximum current efficiency and EQE of 21.2 cd/A and 6.7%, respectively, was achieved for a yellow OLED, while a blue OLED achieved a maximum of 16.5 cd/A and 10.1%, respectively. The increase in light out-coupling from the top-emitting OLEDs led to increase in efficiency by a factor of up to 2.2 relative to the optimised bottom emitting devices, which is the best out-coupling reported using solution processed polymers in a simple architecture and a significant step forward for their use in large area lighting and displays.

Optimized multilayer indium-free electrodes for organic photovoltaics

Flexible multilayer electrodes that combine high transparency, high conductivity, and efficient charge extraction have been deposited, characterised and used as the anode in organic solar cells. The anode consists of an AZO/Ag/AZO stack plus a very thin oxide interlayer whose ionization potential is fine-tuned by manipulating its gap state density to optimise charge transfer with the bulk heterojunction active layer consisting of poly(n-3- hexylthiophene-2,5-diyl) and phenyl-C61-butyric acid methyl ester (P3HT:BC61BM). The deposition method for the stack was compatible with the low temperatures required for polymer substrates. Optimisation of the electrode stack was achieved by modelling the optical and electrical properties of the device and a power conversion efficiency of 2.9% under AM1.5 illumination compared to 3.0% with an ITO-only anode and 3.5% for an ITO:PEDOT electrode. Dark I-V reverse bias characteristics indicate very low densities of occupied buffer states close to the HOMO level of the hole conductor, despite observed ionization potential being high enough. Their elimination should raise efficiency to that with ITO:PEDOT.
