In this paper a search routine in MATLAB was developed in order to find and analyze oblique whistler waves in the data from the ESA and NASA spacecraft Solar Orbiter. Oblique whistler waves are a type of plasma wave which propagate at an angle with respect to the background magnetic field. They are efficient at scattering electrons in the solar wind but their role in interplanetary coronal mass ejections (ICMEs) is yet unknown. Magnetic field data from 1-31st of June 2022, as well as the 24th and 27-28th of January 2022 was examined. The search routine found six whistler waves in June and 12 for the dates in January. Among these, all found whistler waves were found in the sheath region of the ICMEs, and all had a plasma beta > 1. However due to instrumental artefacts the values of θk were found to be smaller than detected by the search routine, indicating less obliqueness than first expected. Some of the whistler waves seemed to have an obliqueness that changed with time and the bandwidth of the waves varied among the identified.

In this thesis, applying an innovative postmodern equal-weight/sequential QUAN→PHEN Mixed-Methods Phenomenological Research (‘MMPR’) approach to study an Olympics’ impact within its two-cluster socio-demographic footprint forms its main contribution to knowledge. Facilitating between-methods triangulation is a novel eclectic pragmatic approach that is used to capture the richness of thematic data flowing from in-depth, open-ended interviews with most – 62 in all – senior Hoteliers spread evenly between distinct urban Metro-Vancouver and rural alpine-Whistler, whilst concurrently capitalizing on the availability of a unique BC Stats proprietary micro-municipal-level secondary data source, i.e., British Columbia’s ‘Additional Hotel Room Tax’ (‘AHRT’). Typically, traditional mono-method-positivist neo-classical economic syntheses are used to quantify an Olympic Games’ ex-ante or ex-post impact. This study’s findings confirm that such syntheses attempts, at the micro-municipal level, lead to inevitable dead-ends. At a sub-national level of micro-granularity, using available economic models is an impossible task due to the insurmountable practical problem of complete lack of, or paucity, of data. When applied to assess mega-events, such modelling is shown to lack credibility; models are insufficiently comprehensive or its users consciously engage in ‘shenanigans’ by force-fitting input/output to produce pre-ordained outcomes for political expedience and meeting agency interests. The ‘MMPR’ approach acknowledges and respects the established and ‘current-thinking’ paradigmatic epistemological and ontological perspectives. ‘Hotel Activity’, measured via ‘AHRT’, is substituted as a ‘Proxy’ for ‘Tourism’ following empirically establishing these three variables as highly correlated. Prevalent academic findings of negative impacts from Winter Olympics are not borne out. Phenomenological issues of ‘illusory correlations’ and ‘data saturation’ are addressed.

This dissertation uncovers three previously unrecognized innovations of Thomas Jeckyll in the Peacock Room. At the same time, the dissertation admits that sometimes James McNeill Whistler chose a more conventional path in the design of the room than previously acknowledged. The dissertation illuminates the often overlooked principle of Classical Decor, first described in the first century BC by Vitruvius, and analyzes how it was instituted in the Peacock Room. Four major points illustrate this conclusion. First, the meaning of the sunflower in the West is explored to account for the flower’s popularity and absorption into ancient heliotropic lore. Thomas Moore’s poetry may have inspired Aesthetic Movement designers such as Jeckyll to use the motif. Second, this dissertation demonstrates that the Peacock Room is only a distant descendant of the traditional European porcelain chamber. It was a new idea to turn the porcelain chamber into a dining room. Further, the room lacks two of the three key features of a porcelain room: lacquer panels and large plate-glass mirrors. When Whistler made the surfaces of this room dark and glossy, he made the room more traditional, aligning it with the customary lacquer paneling of porcelain rooms. And Jeckyll’s sho-dana shelving system in the Leyland dining room was without precedent in porcelain or other kinds of Western rooms, with influences from Japan and China. Third, Decor in the dining room was revealed as an established pattern in eating rooms from Ancient Roman triclinia to the present day. Fourth, Decor is present in the Peacock Room in four ways: in the trappings of the table used to decorate a dining room, in the darkness of this dining room, in the use of a foodstuff, the peacock, to decorate the room, and in the hearth’s sunflowers. Through the lens of the history of Western domestic interiors, significant innovations by Jeckyll have been brought to light, and the meaning of specific elements in the Peacock Room has been elucidated. Jeckyll and Whistler gave the world a sensational story in the Peacock Room but also a complex work of art that is only beginning to be illuminated.

This dissertation, G.A.M.E., refashions James McNeill Whistler’s book, The Gentle Art of Making Enemies, into a hypermediated facsimile text and archive. By remediating the text, the socio-historical context of the Victorian time period in which Whistler lived is reestablished, making his book more accessible to twenty-first century audiences. The era studied in this dissertation includes the expansion of the idea of celebrity, the power of the press, and the concept of art for art’s sake from 1863 through 1892. In order to showcase these concepts, archival materials, such as personal correspondence, newspaper clippings, and published pamphlets, from this period were collected, digitized, and organized into a digital archive and edition. In 1890, Whistler, an American-born, British-based artist known for his arguments with the critics of his day, published The Gentle Art, a collection of previously printed letters and pamphlets. Throughout the book, Whistler refers to people, publications, and events relevant to himself and his work. Persons unfamiliar with those references may find themselves frustrated while reading due to the lost social and historical context referred to on the pages, because those references remain difficult to access. G.A.M.E., makes Whistler’s The Gentle Art more accessible by realizing the proto- hypertextual nature of his book. Like many modern-day websites, The Gentle Art contains numerous references to references – a virtual daisy chain of associations Whistler made to and with his work encircling his artistic philosophy, art for art’s sake. From 1890, when the book was published, until now, Whistler’s “links” have remained dormant on the page. G.A.M.E. activates those links and reanimates The Gentle Art via a hypermediated facsimile text for twenty-first century readers. The Gentle Art of Making Enemies is a window into the late Victorian art world. G.A.M.E. houses and archives this contextual material in order to resurrect The Gentle Art and reconcile it with the man who created it.

<p>Polarisation, which was first studied in optics, is a fundamental property of all electromagnetic fields. A convenient way to describe the polarisation of two dimensional electromagnetic fields is given by the Stokes parameters. This thesis deals with different aspects of wave polarisation and electromagnetic field measurements. A generalisation of the Stokes parameters to three dimensions is presented. The theory has been used to develop methods and systems for obtaining the polarisation parameters of electromagnetic waves. The methods can be applied for a wide range of electromagnetic fields, measured both on ground and onboard satellites. The applications include, e.g., direction-finding, polarisation analysis, radar, and several examples in the field of wireless communication. Further applications are given in the analysis of satellite data, where a whistler wave is considered. Whistlers are circularly polarised electromagnetic waves propagating in the magnetosphere along the geomagnetic field. Dispersion in the magnetospheric plasma make the whistler frequencies travel at different speeds and the signal takes the form of a chirp. From instantaneous polarisation analysis of the whistler´s magnetic wave field, the normal to the polarisation plane is obtained and found to precess around the geomagnetic field. A statistic analysis of ionospheric stimulated electromagnetic emissions (SEE) is also presented. SEE is generated by injecting a powerful high frequency radio wave into the ionosphere. It is shown that the SEE features have a statistical behaviour indistinguishable from the amplitude and phase distributions of narrow-band Gaussian noise. The results suggests that SEE cannot be explained by simple coherent processes alone. Finally, an expression for the complex Poynting theorem is derived for the general case of anharmonic fields. It is found that the complex Poynting theorem, for real fields and sources, is not a conservation law of the imaginary part of electromagnetic energy.</p>

Just prior to the opening of the 2010 Vancouver Olympic Games, a 21-year-old Georgian luger died after his sled left the Whistler Sliding Centre track travelling at 140 kilometres an hour. The following paper uses Critical Discourse Analysis and the Bahktinian notion of intertextuality to examine how Canadian media discursively constructed social media users and their sharing of the images, video, and opinions following the tragedy. The results show traditional media discursively constructed social media as outsiders, separate from the audience, and further argued they need to follow traditional media norms in order to be responsible citizens. In considering this discursive construction within the political economy of traditional media, it is suggested that one tactic employed is the creation of flak, which attempts to discredit what it opposes. Traditional media discourse, sometimes itself the target of flak, here uses flak against social media which are impinging on the political economy of the traditional media.
