National and international aspects of the law relating to aviation

Publisher: name: University Of Tasmania
Year: 2023

description: In this thesis the events leading up to the International Convention of 1919 for the Regulation of Aerial Navigation are briefly outlined, and the position in Australia regarding legislation on air navigation examined. Various Articles of the International Convention are then discussed from the International aspect. Our Commonwealth is one of the parties to this Convention. The Commonwealth legislation and the manner in which it gives effect to the principles of the Convention are therefore the principal matters discussed when dealing with the subject of air navigation from the national aspect. By way of comparison the legislation of other countries, particularly Great Britain, relating to the points discussed, has been examined. The whole of the work on the Australian legislation, both Commonwealth and State, and the comparison of the various Commonwealth Regulations with those of other countries is original. The acts, regulations etc., from which the information on these matters has been obtained, are stated in the notes throughout the thesis. References are given to the works of those writers from which information relating to the International Convention has been obtained. The question of trespass as affecting aviators is dealt with at length, and this has involved consideration of the effect of the maxim \cuius est solum eius est usque ad coelum et ad inferos\". It is a matter of vital importance so far as air navigation is concerned and yet is one on which there is great difference of opinion. In the English legislation special provision is made releasing aviators on certain conditions from liability for trespass but in the Commonwealth legislation the matter is not mentioned. The examination of cases and texts bearing on this question is the writers own research work and was completed before the receipt of Dr McNair's book the Law of the Air. The object has been to examine cases over as wide a period as possible dealing with the interpretation placed upon the above-mentioned maxim. In addition to the International Convention and the Bulletins of the International Commission for Air Navigation and the various Acts and Regulations to which reference is made in the thesis the following works have been consulted :- Abbott Law of Merchant Ships and Seamen (14th Edit.) British Year Books of International Law Clarke & Lindsell Law of Torts (5th Edit.) Hall International Law (7th Edit.) Hazeltine Law of the Air (1911) Halsbury Laws of England Lawrence Principles of International Law (6th Edit.)

description: In this work we present the general phase behavior of short tubelike flexible polymers. The geometric thickness constraint is implemented through the concept of the global radius of curvature. We use sophisticated Monte Carlo sampling methods to simulate small bead-stick polymer models with Lennard-Jones interaction among non-bonded monomers. We analyze energetic fluctuations and structural quantities to classify conformational pseudophases. We find that the tube thickness influences the thermodynamic behavior of simple tubelike polymers significantly, i.e., for given temperature, the formation of secondary structures strongly depends on the tube thickness.

title: Photography and the book: from Fox Talbot to Christian Boltanski
Creators: name: Durden, Mark
Publisher: name: University of Kent
Year: 2021

description: Photography and the Book examines the use of photograph in differing books, from Fox Talbot's The Pencil of Nature to the photo-books of the contemporary French artist, Christian Boltanski. Spanning nearly 150 years of photography, from the first book with photographic plates to artist's books produced from the late 1960s to early 1990s, the choice of books develops a thematics of photography and truth. The thesis consists of two parts, the first looking at photography and the book in the nineteenth century, the second examining books in the twentieth century. My discussion of Talbot's The Pencil of Nature considers the status of this first book with photographic plates, and will be showing gow it reflects a self-reflexive fascination with photography. Chapter Two looks at the photo-books of Peter Henry Emerson, discussing his attempts to bring photography closer to the truth of a corporealised vision. Chapter three discusses photography as described in two nineteenth century novels, as a means of revealing truth of character in Hawthorne's The House of the Seven Gables and as a means of deception and misrepresentation in Thomas Hardy's A Laodicean. Chapter four looks at truth in books of science, focusing on the use of the composite photograph as a means of representing the essence of criminality. Part two begins with an analysis of James Agee's and Walker Evans's documentary book, Let Us Now Praise Famous Men. It examines the problematics involved in representing poverty. Chapter six will consider the photo-texts of the American writer and photographer, Wright Morris. Here photography, particularly the amateur snapshot, is treated as a talismanic object and stands for a particular truth of experience. The following discussion of Roland Barthes's Camera Lucida will examine the role of photography in a book of theory, behind which lies a metaphysical attachment to the evidential force of certain photographs. An analysis of the artist's books of Christian Boltanski will bring the thesis to a close and up to date, as I examine the whole issue of truth and photography through such bookworks as Detective which mixes uncaptioned portraits of killers and their victims, a book of portraits which exposes photography's limited capacity to convey information about those depicts.

description: © 2016 Pacheco et al. Background: Multiplicity of infection (MOI) refers to the average number of distinct parasite genotypes concurrently infecting a patient. Although several studies have reported on MOI and the frequency of multiclonal infections in Plasmodium falciparum, there is limited data on Plasmodium vivax. Here, MOI and the frequency of multiclonal infections were studied in areas from South America where P. vivax and P. falciparum can be compared. Methodology/Principal Findings: As part of a passive surveillance study, 1,328 positive malaria patients were recruited between 2011 and 2013 in low transmission areas from Colombia. Of those, there were only 38 P. vivax and 24 P. falciparum clinically complicated cases scattered throughout the time of the study. Samples from uncomplicated cases were matched in time and location with the complicated cases in order to compare the circulating genotypes for these two categories. A total of 92 P. vivax and 57 P. falciparum uncomplicated cases were randomly subsampled. All samples were genotyped by using neutral microsatellites. Plasmodium vivax showed more multiclonal infections (47.7%) than P. falciparum (14.8%). Population genetics and haplotype network analyses did not detect differences in the circulating genotypes between complicated and uncomplicated cases in each parasite. However, a Fisher exact test yielded a significant association between having multiclonal P. vivax infections and complicated malaria. No association was found for P. falciparum infections. Conclusion: The association between multiclonal infections and disease severity in P. vivax is consistent with previous observations made in rodent malaria. The contrasting pattern between P. vivax and P. falciparum could be explained, at least in part, by the fact that P. vivax infections have lineages that were more distantly related among them than in the case of the P. falciparum multiclonal infections. Future research should address the possible role that acquired immunity and exposure may have on multiclonal infections and their association with disease severity.

description: © 2016 Stanley and Kulathinal. Background: Domesticated animals quickly evolve docile and submissive behaviors after isolation from their wild conspecifics. Model organisms reared for prolonged periods in the laboratory also exhibit similar shifts towards these domesticated behaviors. Yet whether this divergence is due to inadvertent selection in the lab or the fixation of deleterious mutations remains unknown. Results: Here, we compare the genomes of lab-reared and wild-caught Drosophila melanogaster to understand the genetic basis of these recently endowed behaviors common to laboratory models. From reassembled genomes of common lab strains, we identify unique, derived variants not present in global populations (lab-specific SNPs). Decreased selective constraints across low frequency SNPs (unique to one or two lab strains) are different from patterns found in the wild and more similar to neutral expectations, suggesting an overall accumulation of deleterious mutations. However, high-frequency lab SNPs found in most or all lab strains reveal an enrichment of X-linked loci and neuro-sensory genes across large extended haplotypes. Among shared polymorphisms, we also find highly differentiated SNPs, in which the derived allele is higher in frequency in the wild (Fstwild>lab), enriched for similar neurogenetic ontologies, indicative of relaxed selection on more active wild alleles in the lab. Conclusions: Among random mutations that continuously accumulate in the laboratory, we detect common adaptive signatures in domesticated lab strains of fruit flies. Our results demonstrate that lab animals can quickly evolve domesticated behaviors via unconscious selection by humans early on a broad pool of disproportionately large neurogenetic targets followed by the fixation of accumulated deleterious mutations on functionally similar targets.

description: We present a detailed description of the nature of the wavefunction and spin distribution of the zero energy modes of zigzag graphene ribbons (ZGRs) in the presence of the intrinsic spin_orbit (I-SO) interaction. These states characterize the quantum spin Hall (QSH) phase in graphene ribbons. We provide analytic expressions for wavefunctions and show how these evolve as the strength of the interaction and the ribbon width are changed. For odd-width ribbons, we show that its insulating nature precludes the existence of a QSH phase. For these systems the I-SO interaction is predicted to have a stronger effect as shown by the enhancement of the gap as the interaction strength is turned on.

title: Social Banditry: How authorities' irresponsiveness fosters support for vicarious dissent
Creators: name: Heering, Maria Sophia
Publisher: name: University of Kent
Year: 2021

description: Individuals who cannot directly express their discontents against an unjust system may instead support groups that disrupt the system through deviant, transgressive or even criminal actions. These groups are defined as 'social bandits', and their actions may be construed as a form of vicarious protest. Very little research has examined what drives individuals' support for social bandits. This thesis focused on hackers, groups operating on the internet often illegally. Seven experiments examined the circumstances in which individuals were more likely to support hackers engaging in disruptive and criminal actions. Experiments 1-2 examined whether individuals were more likely to support hackers that attacked a corrupt (either ingroup or outgroup) authority. Results indicated that individuals legitimized hackers more strongly when they attacked an ingroup corrupt authority. Experiments 3-4 extended these findings focusing on the role of an institution' responsiveness. In two different contexts (online work platform and university), participants who dealt with an institution irresponsive to their grievances were more likely to experience anger and, subsequently, legitimize hackers' attacks. Experiments 5-6 explored the role of schadenfreude. These experiments showed how both government corruption (studies 5 and 6) and low government responsiveness (study 6) may trigger schadenfreude in response to hackers' attack, and stronger support for hackers. Experiment 7 consolidated previous findings and explored the role of identification with an aggrieved group. In this study, low responsiveness elicited anger and schadenfreude, which then predicted increased support for hackers. Results also revealed an interaction effect of identification with an aggrieved group participants belonged to, and emotions on the legitimization of hackers; individuals who identified more strongly with the aggrieved group expressed lower anger and schadenfreude and consequently lower support for hackers (Study 7). Theoretical implications for the emerging field of research on social bandits are discussed, in addition to future directions for research.

description: We reexamine the theoretical instability domain of pulsating DB white dwarfs (DBV or V777 Her variables). We performed an extensive $g$-mode nonadiabatic pulsation analysis of DB evolutionary models considering a wide range of stellar masses, for which the complete evolutionary stages of their progenitors from the ZAMS, through the thermally pulsing AGB and born-again phases, the domain of the PG1159 stars, the hot phase of DO white dwarfs, and then the DB white dwarf stage have been considered. We explicitly account for the evolution of the chemical abundance distribution due to time-dependent chemical diffusion processes. We examine the impact of the different prescriptions of the MLT theory of convection and the effects of small amounts of H in the almost He-pure atmospheres of DB stars on the precise location of the theoretical blue edge of the DBV instability strip.

description: We consider a general class of vector-tensor theories of gravity and show that solutions with accelerated expansion and a future type III singularity are a common feature in these models. We also show that there are only six vector-tensor theories with the same small scales behavior as General Relativity and, in addition, only two of them can be made completely free from instabilities. Finally, two particular models as candidates for dark energy are proposed: on one hand, a cosmic vector that allows to alleviate the usual naturalness and coincidence problems and, on the other hand, the electromagnetic field is shown to give rise to an effective cosmological constant on large scales whose value can be explained in terms of inflation at the electroweak scale.

The refractive index and wave vector in passive or active media

Publisher: name: arXiv
Year: 2009
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: Materials that exhibit loss or gain have a complex valued refractive index $n$. Nevertheless, when considering the propagation of optical pulses, using a complex $n$ is generally inconvenient -- hence the standard choice of real-valued refractive index, i.e. $n_s = \RealPart (\sqrt{n^2})$. However, an analysis of pulse propagation based on the second order wave equation shows that use of $n_s$ results in a wave vector \emph{different} to that actually exhibited by the propagating pulse. In contrast, an alternative definition $n_c = \sqrt{\RealPart (n^2)}$, always correctly provides the wave vector of the pulse. Although for small loss the difference between the two is negligible, in other cases it is significant; it follows that phase and group velocities are also altered. This result has implications for the description of pulse propagation in near resonant situations, such as those typical of metamaterials with negative (or otherwise exotic) refractive indices.

description: We study the vector-vector interaction within the framework of the hidden gauge formalism for the channels with quantum numbers Charm C=0 and Strangeness S=0 in the energy region around 4000 MeV. By looking for poles in the complex plane we find three resonances that could be identified by the mass, width and quantum numbers with the Y(3940), Z(3940) and X(4160), these poles appear with isospin I=0 and J^{PC}=0^{++}, 2^{++} and 2^{++} respectively. Whereas the Y(3940) and Z(3940) are coupled more strongly to D^*\bar{D}^*, the X(4160) is basically a D^*_s \bar{D}^*_s molecular state. Another two extra resonances appear in our approach with I=0, 1 and J^{PC}=1^{+-}, 2^{++} which are not found in the PDG with masses M=3945, 3912 MeV and widths Γ=0, 120 MeV respectively.

Based on more recent developments in the project as they are documented in T6.1, D1.2, the present Deliverable D3.2 now focuses on guiding the user experience (UX) development in a concrete and fine-grained manner. Interface components are discussed in detail in relation to the cognitive principles provided by the predecessor deliverable in view of the upcoming design decisions to be made. At the time of writing, the platform’s application domain, designing within today’s AEC industries, has not been studied comprehensively so that guidance in the development process cannot solely rely on existing research and empirical studies. ETH therefore expects that developing studies on cognitive aspects as well as the testing of the user interface will be an ongoing activity that takes place in a step-by-step manner and in close coordination with all project partners. In preparation for upcoming empirical work the deliverable discusses options for controlled studies alongside highlighting the advantages of more qualitative interview- and observation-based approaches, especially when working with small samples of highly specialised expert users.

description: © 2016, BMJ Publishing Group. All rights reserved. Objectives: This study addresses the lack of empirical studies about the epidemic of syphilis among middleaged female sex workers (FSWs). The objectives of this study were to investigate prevalence of syphilis, and its potential risk factors among middle-aged FSWs in China. Design: A cross-sectional study with respondent-driven sampling (RDS). Setting: A multisite study conducted at three Chinese cites (Nanning, Hefei, and Qingdao) with different levels of sexually transmitted diseases in 2014. Participants: 1245 middle-aged female sex workers who were over 35 years old (about 400 per study site). Main outcome measures: Unprotected commercial sex, and syphilis and HIV infection were biologically tested and measured. Results: The RDS-adjusted prevalence of active syphilis was 17.3% in Hefei, 9.9% in Qingdao, and 5.4% in Nanning. The RDS-adjusted prevalence of prevalent syphilis was between 6.8% and 33.6% in the three cities. The proportion of unprotected sex in the past 48 h verified by the prostate-specific antigen test (PSA) was between 27.8% and 42.4%. Multiple logbinomial regression analyses indicate that middle-aged FSWs who had 5 or more clients in the past week prior to interviews and engaged in unprotected sex were more likely to be active syphilitic cases. Middle-aged FSWs who had rural residency were less likely to be active syphilitic cases. Conclusions: In contrast with previous studies that reported low prevalence of syphilis and high prevalence of protected sex among FSWs in China, both the prevalence of syphilis and unprotected sex were high among middle-aged FSWs. Evidence-based intervention programmes should be developed and evaluated among this vulnerable population in China and other countries with similar settings.

Graphene zigzag ribbons, square lattice models and quantum spin chains

description: We present an extended study of finite-width zigzag graphene ribbons (ZGRs) based on a tight-binding model with hard-wall boundary conditions. We provide an exact analytic solution that clarifies the origin of the predicted width dependence on the conductance through junctions of ribbons with different widths. An analysis of the obtained solutions suggests a new description of ZGRs in terms of coupled chains. We pursue these ideas further by introducing a mapping between the ZGR model and the Hamiltonian for N-coupled quantum chains as described in terms of 2N Majorana fermions. The proposed mapping preserves the dependence of ribbon properties on its width thus rendering metallic ribbons for N odd and zero-gap semiconductor ribbons for N even. Furthermore, it reveals a close connection between the low-energy properties of the ZGR model and a continuous family of square lattice model Hamiltonians with similar width-dependent properties that includes the $π-$flux and the trivial square lattice models. As a further extension, we show that this new description makes it possible to identify various aspects of the physics of graphene ribbons with those predicted by models of quantum spin chains (QSCs).
Sex-biased cellular signaling: Molecular basis for sex differences in neuropsychiatric diseases

description: © 2016 AICH-Servier Research Group. All rights reserved. The recognition that there are fundamental biological sex differences that extend beyond those that define sexual behavior and reproductive function has inspired the drive toward inclusion of both sexes in research design. This is supported by an underlying clinical rationale that studying both sexes is necessary to elucidate pathophysiology and develop treatments for the entire population. However, at a more basic level, sex differences, like genetic differences, can be exploited to better understand biology. Here, we discuss how sex differences at the molecular level of cell signaling and protein trafficking are amplified to create a state of vulnerability that under the right conditions can result in symptoms of neuropsychiatric disease. Although this dialogue focuses on the specific example of corticotropin- releasing factor, the potential for analogous sex differences in signaling and/or trafficking of receptors for other neuromodulators has broad biological and therapeutic implications.

description: We review our recent results of Alfven wave-driven winds. First, we present the result of a self-consistent 1D MHD simulations for solar winds from the photosphere to interplanetary region. Here, we emphasize the importance of the reflection of Alfven waves in the density stratified corona and solar winds. We also introduce the recent HINODE observation that might detect the reflection signature of transverse (Alfvenic) waves by Fujimura & Tsuneta (2009). Then, we show the results of Alfven wave-driven winds from red giant stars. We explain the change of the atmosphere properties from steady coronal winds to intermittent chromospheric winds and discuss how the wave reflection is affected by the decrease of the surface gravity with stellar evolution. We also discuss similarities and differences of accretion disk winds by MHD turbulence.
