description: Elementary physics of photovoltaic energy conversion in a two-level atomic PV is considered. We explain the conditions for which the Carnot efficiency is reached and how it can be exceeded! The loss mechanisms - thermalization, angle entropy, and below-bandgap transmission - explain the gap between Carnot efficiency and the Shockley-Queisser limit. Wide varieties of techniques developed to reduce these losses (e.g., solar concentrators, solar-thermal, tandem cells, etc.) are reinterpreted by using a two level model. Remarkably, the simple model appears to capture the essence of PV operation and reproduce the key results and important insights that are known to the experts through complex derivations.

description: Avian pathogenic Escherichia coli (APEC) causes colibacillosis, a poultry disease which results in losses to the Canadian egg-industry. Colibacillosis in Canada cannot be treated with antibiotics due to Canadian Food Inspection Agency regulations, necessitating novel APEC control strategies. Phage biocontrol and tannin feed inclusion have been successful in reducing APEC infection in broiler chickens. We hypothesized that phages and tannins would be effective in treating colibacillosis in laying hens. The study objectives were to isolate and characterize anti-APEC phages for use in a laying hen model, test purple prairie clover (PPC) and brown seaweed (BSW) tannin efficacy against APEC in vitro and develop a laying hen APEC infection model for assessment of phage colibacillosis control. Phages targeting APEC strains were isolated from sewage and hen feces. The host range and lytic activity of seven isolated phages were determined using microplate phage virulence assays. Tannin efficacy was assessed using minimum inhibitory concentration (MIC) assays against APEC strains, and a laying hen APEC infection model was established via air sac APEC injection. Phages were subjected to transmission electron microscopy to determine morphology and pH tolerance assays were conducted to determine pH stability. Phage genomic DNA were extracted and sequenced via the Illumina MiSeq platform. Raw sequence reads were assembled and annotated via a variety of programs. To understand the relationship between the novel phages and their relatives, comparative genomic and proteomic analysis as well as phylogenetic trees were also conducted via standard programs. Four of seven phages possessed strong lytic activity against multiple APEC strains and phages were more stable between pH = 3.5 and 9.0 than at pH = 2.5. Whole-genome sequencing data showed there are four phages of the Myoviridae, one of the Autographiviridae, and two of the Siphoviridae families. PPC and BSW tannins both inhibited APEC growth in vitro (MIC < 150 µg/mL). The air-sac infection model was unsuccessful due to an insufficient infectious dose. Results show promise for the use of phages and tannins for the control of colibacillosis in laying hens.

description: We consider the possibility that along the thermal history of the Universe, dark matter (DM) would have been created from Standard Model particles, either through a kinetic mixing portal to an extra U(1) gauge field, or through the Higgs portal. Depending solely on the DM particle mass, on the portal and on the DM hidden sector interaction, we show how the observed DM relic density can be obtained. There are four possible freeze-in/reannihilation/freeze-out regimes, which together result in a simple characteristic relic density phase diagram, with the shape of a "Mesa". In the case of the kinetic mixing portal, we show that, unlike other freeze-in scenarios discussed in the literature, the freeze-in regime can be probed by forthcoming DM direct detection experiments. These results are well representative {of} any scenario where a DM hidden sector would be created out of the Standard Model {sector}.

Le emozioni come effetti di discorso

description: Human and social studies on emotions are diversely interested in the reality emotions signify. Within this field, the discourse analysis approach focuses its attention on the linguistic expression of emotions and cannot thus extend its evaluation on psychological or sociological implications. What is said can be only explored at a linguistic level,  also from a rhetorical perspective that looks at the effects created by discourse categories and topical construction of emotions. Knowledge of findings in related disciplines will  nevertheless  facilitate the deciphering of discourse analysis of the  mechanisms underlying the subject’s intentions, social interactions or representations.  
In this paper, great attention will be paid to the notion of the intentional value of emotions and of their cognitive content. This pertains to a kind of knowledge derived from belief rather than a form of knowledge earned through evidence. As a sensitive reaction to sensation, emotion expresses itself in behaviour, but as  a form of knowledge, emotion has anyhow a rational value based on social agreement and collective representations.
Within a discourse analysis’ perspective, emotions and the knowledge they involve are nevertheless the effect not only of what words signify on an emotional ground, but also of the context, the situation and the speakers’ identities. These factors, the interaction of which can be studied from a rhetorical point of view, are to be considered when the influence on  others is the aim of a speech, as happens in political discourse.

Restoration of plant communities to red-burned soils
Creators: name: DeSandoli, Lisa Ann
Publisher: name: University of British Columbia
Year: 2013

description: Fire, natural or anthropogenic, is a common occurrence in the open forests and grasslands of Western North America. The effects of fire on soil and vegetation depend largely on the soil temperatures and the residence time of the burn. Generally, the more severe the fire, the more significant the changes are to soil and vegetation. The relationship between the most severe fires, or where the soil has been oxidized to a red colour, and invasive species is unknown. Resource availability may increase on these soils, leading to favourable conditions for invasive species, or the disturbance may be so severe that nothing is able to grow indefinitely. I performed two studies to investigate the relationship between invasive species and red-burned soil. To reduce the threat of interface fires near Kamloops, BC, excess timber was harvested, piled and burned on site (pile burning), created multiple burn scars denuded of vegetation and large areas of red soil. In the first study, I investigated soil nutrient flux differences between red-burned and unburned soil using ion-exchange resin technology. I also investigated three restoration methods to control invasive species: the addition of agronomic or native seed, the addition of arbuscular mycorrhizal fungi (AMF) inoculum, and the addition of soil cover. Non-native species cover was high on red soil 2 years post-burn, which may be linked to measured increased nutrients. Only the addition of agronomic seed was successful at suppressing non-native species cover. The second study compared the growth of native, agronomic and invasive species on unburned and red-burned soil in a greenhouse study. Soil was collected in the field and transferred to a greenhouse. Treatments were soil burning, AMF, and watering. Burning increased aboveground biomass for the native species. AMF addition increased invasive species aboveground biomass for the invasive species, but decreased biomass for agronomic and native species. Watering increased aboveground biomass for the agronomic and invasive species. The findings here suggest that pile burning creates areas that are susceptible to colonization of non-native species. Restoration efforts should be directed at these sites as soon as possible to ameliorate the effects of invasive species colonization.
Communication politique et passion

description: The interaction between communication, politics and passion holds reality together, the analysis of which leads to a better knowledge of the foundation of the civil bond. If the concepts individually offer a first approach to the comprehension of this interaction, their common use of language gives us a deeper understanding of the public word (concerning public questions and addressed to the people) as a medium towards a collective will and as an instrument to transform single attitudes. This aim is achieved through the clever expression of one's own or other's feelings or emotions as learnt through  the rhetorical art: the ethos or pathos construction is thus a sign of how the passion underlying public communication has a political end. Nevertheless, the cognitional nature of passion lets us understand that this is the real condition of the civil bond and therefore the origin of both politics and communication.

description: Autistic adults experience disproportionate rates of co-occurring mental health problems. While psychotherapy has been recognized as an appropriate treatment approach for the mental healthproblems experienced by this population, the evidence is still rather limited. Further, the literature is incomplete when it comes to understanding the needs and preferences of autistic adults who receive mental health support in the form of psychotherapy. Given the need to better inform mental health interventions and improve access to mental health services for this population, the current study used qualitative methods to explore critical experiences thatfacilitated or served as barriers to psychotherapy, in the context of receiving this treatment for mental health problems by autistic adults. The Enhanced Critical Incident Technique was used toexplore the subjective experiences of 13 mental health providers who have experience providing psychotherapy to autistic adults with mental health problems, along with the perspectives ofeight autistic adults who have received this type of care. Both groups of participants identified salient experiences that served as barriers to, and facilitators of positive experiences in psychotherapy. Moreover, both mental health providers and autistic adults offered several recommendations, provided through the identification of wish list items, that were believed to enhance experiences in psychotherapy. Together, these perspectives lend towards a more complete understanding of how we can best inform clinical practice when providing psychotherapy for autistic adults with mental health problems. This research highlights challenges to providing psychotherapy to autistic adults whilealso illuminating ways that mental health providers have worked to ameliorate such challenges and create positive experiences in therapy. Additionally, this research sheds light on similaritiesand differences in therapy for autistic adults relative to the general population. The experiences identified by participants in this study demonstrate that positive experiences in therapy are indeed possible when there is a foundation of trust and respect in the therapeutic relationship, providers are knowledgeable about autism spectrum disorder, and treatment is delivered in an individualized fashion. Barriers revealed by participants suggests that there is still substantial room for enhancing mental health care of autistic people. The findings from this research add to the limited literature, while also informing clinical practice for mental health providers, future research, and policy planning.
The formation of supported lipid bilayers on nanoparticles as tools to further explore plasmonic properties

description: Forming a bilayer of lipids on the surface of various nanoparticles has been gaining popularity in the literature since the initial study by Mornet et al. (2005). The initial supported lipid bilayer system was formed on silica nanoparticles and explored for applications such as drug delivery. However, the main limitation is that these systems are currently characterized predominantly by cryo-TEM. Based on the limited accessibility of cryo-TEM, the first goal explored within this thesis was to assess whether a supported lipid bilayer on silica nanoparticles could be characterized by other techniques. The results indicate that zeta potential and conventional transmission electron microscopy work as characterization tools to confirm the presence of a supported lipid bilayer on the surface of silica nanoparticles. With our new characterization approach, we expand our research to engineer a new nanoparticle supported lipid bilayer system, a silver core – silica shell supported lipid bilayer (Ag@SiO2 SLB). Silver was chosen as a core material because of its plasmonic properties. The Ag@SiO2 supported lipid bilayer was synthesized and characterized using dynamic light scattering, zeta potential and UV-VIS spectroscopy. A wide range of imaging techniques have also been implemented to obtain direct evidence of the lipid deposition on the surface of the nanoparticle, such as TEM, cryo-TEM, HR-TEM, staining and EDX. Despite our effort, direct evidence has yet to be obtained. Ag@SiO2 SLB was also investigated for its ability to enhance fluorescence via plasmonic effect. Herein, it was shown that the Ag@SiO2 SLB follows distance dependant fluorescence enhancement trends. Taken together a novel material was synthesized, characterization was expanded, and potential applications expanded the value of the SLB system.

description: A theoretical model describing the Raman scattering process in atomic vapors is constructed. The treatment investigates the low-excitation regime suitable for modern experimental applications. Despite the incorporated decoherence effects (possibly mode dependent) it allows for a direct separation of the time evolution from the spatial degrees of freedom. The impact of noise on the temporal properties of the process is examined. The model is applied in two experimentally relevant situations of ultra-cold and room-temperature atoms. The spatial eigenmodes of the Stokes photons and their coupling to atomic excitations are computed. Similarly, dynamics and the waveform of the collective atomic state are derived for quantum memory implementations.

description: Social species, by definition, utilize social interactions with others that are essential for survival and reproductive success. Social interactions can mitigate the harmful effects of stress through a process known as social buffering. Our understanding of the cellular mechanisms that underlie social buffering, however, is poor. Acute stress primes glutamate synapses onto corticotropin-releasing hormone (CRH) neurons in the paraventricular nucleus (PVN) of the hypothalamus (CRHPVN neurons), resulting in stress-induced metaplasticity. This priming of synapses, which manifests as short-term potentiation (STP) of excitatory transmission elicited by high-frequency afferent stimulation, is buffered in female but not male mice by the presence of a naive partner. The cellular substrates underlying this sex-specific buffering of these synaptic changes have not been elucidated. Increasing evidence suggests that neurons in the PVN are sensitive to neuromodulation by locally released substances. Here, I tested the hypothesis that local vasopressin (VP) signaling in the PVN contributes to social buffering of synaptic metaplasticity in females. I used whole-cell patch clamp recordings from CRHPVN neurons to examine the effects of VP on STP in these cells. I found that selective pharmacological blockade of VP 1a receptors prevented social buffering of STP. Conversely, exogenous VP mimicked the effects of social buffering and reduced STP in CRHPVN neurons from single-housed stressed females but had no effect in males. These synaptic actions rely on direct VP signaling on CRHPVN neurons that reduce the AMPA/NMDA ratio. In addition, I extended the effects of social buffering to cognitive functions and examined how changes in CRHPVN neuron activity influence memory retrieval. I found that social buffering improves stress-induced impairments in long-term memory retrieval in female mice, but not in males. Furthermore, optogenetic silencing of CRHPVN neurons in single-housed stressed female mice reduced STP and replicated the social buffering effect by improving memory retrieval after stress. Collectively, the work in this thesis contributes to our understanding of the mechanism that underlies sex-specific social buffering of STP and provides evidence that the effects of social buffering may be determined by changes in CRHPVN neuron activity.
La mise en scène de la passion par les professionnels de la politique

description: Contemporary politics stands on an ambiguous relationship with passion. Firstly, passion is, clearly, the very reason of a concern which justifies one's political involvement and frees himself of a narrow interest, merely waiting, as Olson said, on material advantages. But the capacity of passion to disrupt institutions and to cause the loss of social peace is also self-evident. As a result, representative democracy remains within the limits marked by a reasonable involvement, basing itself on an optimum of indifference (see Braud, 1991). Democracy will therefore prefer citizens scarcely passionate about politics, in order to let the democratic activities or civil celebrations be  performed. If the concern with politics is the condition of democratic legitimacy, the excess of involvement disturbs professional politics: passion wouldn't then be an acceptable attitude if it weren't regulated by civic self-control.

Resummation Properties of Jet Vetoes at the LHC

description: Jet vetoes play an important role at the LHC in the search for the Higgs and ultimately in precise measurements of its properties. Many Higgs analyses divide the cross section into exclusive jet bins to maximize the sensitivity in different production and decay channels. For a given jet category, the veto on additional jets introduces sensitivity to soft and collinear emissions, which causes logarithms in the perturbative expansion that need to be resummed to obtain precise predictions. We study the higher-order resummation properties of several conceptually distinct kinematic variables that can be used to veto jets in hadronic collisions. We consider two inclusive variables, the scalar sum over pT and beam thrust, and two corresponding exclusive variables based on jet algorithms, namely the largest pT and largest beam thrust of a jet. The inclusive variables can, in principle, be resummed to higher orders. We show that for the jet-based variables, there are dual effects due to clustering in the jet algorithm for both large and small jet radius R that make a complete resummation at or beyond next-to-leading logarithmic order (NLL) challenging. For R~1, the clustering of soft and collinear emissions gives O(1) contributions starting at next-to-next-to-leading logarithmic order that are not reproduced by an all-orders soft-collinear factorization formula and therefore are not automatically resummed by it. For R<<1, clustering induces logarithms of R that contribute at NLL in the exponent of the cross section, which cannot be resummed with currently available methods. We explicitly compute the leading jet clustering effects at two loops and comment on their numerical size.

description: Antibiotic resistance poses a major threat to global public health. Antibiotic potentiators work to circumvent this resistance, and some bacteria produce natural antibiotic potentiators. However, the prevalence of other bacteria that have the capacity to produce antibiotic potentiators remains poorly studied. Here, we developed a natural product pipeline to search for microbial metabolites that can thwart carbapenem resistant Pseudomonas aeruginosa, listed by the World Health Organization (WHO) as a critical priority pathogen for the research and development of new antibiotics. Carbapenems are antibiotics of last resort. This work was enabled by building the Alberta Microbiota Repository (AMBR), which is an open-source biorepository containing more than 762 strains of bacteria and fungi, representing ?272 unique species from ?128 genera. These strains were cultivated from various clinical, animal and environmental sources. By medium-throughput screening, we tested spent media from 348 AMBR isolates, in the presence and absence of meropenem (MEM), against an OprD porin deficient strain of P. aeruginosa that is resistant to carbapenems. We found that spent media from 13 microbial isolates reduced growth of resistant P. aeruginosa by up to 100% and killed >90% of test bacteria, when combined with 32 ?g ml-1 of meropenem. With collaborators, we isolated and identified the bioactive compounds from the spent medium of Neisseria perflava RP9, Staphylococcus lugdunensis 47, and Aeromonas sp. CCT22 using chemical fractionation, mass spectrometry and nuclear magnetic resonance. All of these strains produced a low molecular weight compound that lacks antimicrobial activity but instead functions to sensitize P. aeruginosa to antibiotics. Structure-activity relationship studies identified the chemical groups important for antibiotic potentiation by this molecule. A chemical and genetic analysis revealed that this molecule facilitates antibiotic potentiation by compromising the cell envelope of Gram-negative bacteria to enhance the uptake and accumulation of antibiotics. Taken together, our research provides a technology platform that can be used to devise strategies to mitigate antimicrobial resistance in humans, plants or animals.

description: The merging of political sphere, popular culture and media narrations is one of the most interesting features of today’s political communication on a global scale. The “mediatization” of politics finds its full manifestation in the sweeping process of the popularization of political discourse.  The mutual adaptation between television – with its drives for entertainment,  spectacle and audience ratings – and politics striving for public attention has generated the “pop politics”. The rise of the so-called infotainment and politainment in the political discoruse addresses the question whether and to what extent this type of political communication affects the civic culture and political participation.

description: Upconversion of infrared photons is a promising possibility to enhance solar cell efficiency by producing electricity from otherwise unused sub-band-gap photons. We present a rate equation model, and the relevant processes, in order to describe upconversion of near-infrared photons. The model considers stimulated and spontaneous processes, multi-phonon relaxation and energy transfer between neighboring ions. The input parameters for the model are experimentally determined for the material system β-NaEr0.2Y0.8F4. The determination of the transition probabilities, also known as the Einstein coefficients, is in the focus of the parameterization. The influence of multi-phonon relaxation and energy transfer on the upconversion are evaluated and discussed in detail. Since upconversion is a non-linear process, the irradiance dependence of the simulations is investigated and compared to experimental data of quantum efficiency measurements. The results are very promising and indicate that upconversion is physically reasonably described by the rate equations. Therefore, the presented model will be the basis for further simulations concerning various applications of upconversion, such as in combination with plasmon resonances in metal nanoparticles.

description: In Northern Ireland, the conflict between Unionists and Republicans, Catholic and Protestants saw its peak during the ‘Troubles' of 1969-1993. Today, after four decades of physical violence, the peace process has reached a successful ending and a war of words has finally replaced real war.
    To study how this move from arms to political debate occurred, a written corpus was collected, comprising annual party conference speeches given during the years 1993-2004 by the leaders of the two main and opposed political parties of Northern Ireland, Gerry Adams and Ian Paisley. By comparing these texts, it was possible to observe the development of their discourse from a short-term diachronic perspective.
    A Critical Discourse Analysis approach is considered particularly suitable for dealing with political speeches, but contributions from different fields and disciplines are also considered.
    The discourse analysis of the texts collected is supported by computer-aided analysis. Two aspects are being focussed on, in particular: 1) the use of same/different linguistic resources by the same orators to discuss same/different subjects over the years; and 2) the overall influence of language on politics, i.e. how words are used to exercise power.
    It is hoped that the present study may help clarify aspects of the evolution of political discourse in Northern Ireland, in general, and of the argumentative skills and strategies of the above two politicians, in particular.

Mass imbalance effect in resonant Bose-Fermi mixtures

description: We consider a homogeneous Bose-Fermi mixture, with the boson-fermion interaction tuned by a Fano-Feshbach resonance, in the presence of mass and density imbalance between the two species. By using many-body diagrammatic methods, we first study the finite-temperature phase diagram for the specific case of the mass-imbalanced mixture $^{87}$Rb $-^{40}$K for different values of the density imbalance. We then analyse the quantum phase transition associated with the disappearance at zero temperature of the boson condensate above a critical boson-fermion coupling. We find a pronounced dependence of the critical coupling on the mass ratio and a weak dependence on the density imbalance. For a vanishingly small boson density, we derive, within our approximation, the asymptotic expressions for the critical coupling in the limits of small and large mass ratios. These expressions are relevant also for the polaron-molecule transition in a Fermi mixture at small and large mass ratios. The analysis of the momentum distribution functions at sufficiently large density imbalances shows an interesting effect in the bosonic momentum distribution due to the simultaneous presence of composite fermions and unpaired fermions.

Othering Obama: How Whiteness is Used to Undermine Authority
Creators: name: Owen, David
Publisher: name: Università degli  Studi di Milano
Year: 2010
Subjects: Obama; whiteness; oppression; racism; discourse

description: In this paper, I argue that the sociocultural structuring property of whiteness has been utilized to marginalize President Obama and effectively undermine his presidential authority.  Whiteness functions in a largely invisible and ostensibly deracialized way to normalize the interests, needs, and values of whites, while at the same time marginalizing and devaluing the voice of people of color.  Analyzing the health care debate through this theoretical lens generates insights into how the debate reproduced the system of racial oppression, and how whiteness functions in political discourse.

Recoupling the non-secular part of nuclear spin-spin interaction in solids

description: NMR spin-spin relaxation in solids in strong magnetic fields is normally described only with the help of the secular part of the full spin-spin interaction Hamiltonian. This approximation is associated with the averaging of the spin-spin interaction over the fast motion of spins under the combined action of the static and the radio-frequency (rf) fields. Here we report a set of conditions when the averaging over the above fast motion preserves some of the non-secular terms entering the full interaction Hamiltonian. These conditions relate the value of the static magnetic field with the frequency and the amplitude of the rf field. When the above conditions are satisfied, the effective recoupled spin-spin interaction Hamiltonian has an unconventional form with tunable parameters. These tunable Hamiltonian offers interesting possibilities to manipulate nuclear spins in solids and can shed new light on the fundamental properties of the nuclear spin-spin relaxation phenomenon.

description: Many areas in Canada especially Alberta have recently seen big cryptocurrency mining loads appear on their grid. This is an increasing trend. These loads seem to have very unregulated patterns; hence, they tend to make net load forecasts unreliable for small regional load entities like small cities. According to the literature review that was performed, no work was available that looked at forecasting regional load patterns that are heavily influenced by cryptocurrency mining operations. That became a goal for this research work. This work was done for a particular city in Alberta in partnership with an Alberta-based company. This work is in the pipeline to be commercialized by that same company and it will ultimately be used by the city. A review of how blockchain technology and cryptocurrency mining operation works was performed first. A detailed methodology was proposed to create a forecasting algorithm. It included investigating which input variables, imputation techniques, data processing techniques etc. are useful for the algorithm. Six methodology cases were proposed as part of that, and python coding work was done to implement the proposed methodology. Results were generated based on that implementation and they were analyzed in detail. A final forecasting algorithm was chosen that showed good accuracy measures.
Justifying the Inevitable: How Observers of Mistreatment Can Perpetuate Mistreatment

description: Observers of workplace mistreatment are embedded within organizations—the same organizations in which mistreatment has occurred. Importantly, organizations represent social systems: they provide structure, create predictability, and offer resources to its employees. Attributes of the organizational system may guide observers’ reactions to mistreatment. Drawing on system justification theory (Jost & Banaji, 1994), the current research examines how perceiving the mistreatment incident as inevitable may shape observers’ reactions towards the mistreatment incident and the target of mistreatment. Specifically, I propose that perceived mistreatment inevitability can trigger system justification tendencies, which may prompt observers’ behaviors aimed at maintaining or even perpetuating mistreatment within the organizational system. I also explore the role of perceived mistreatment tolerance climate as an antecedent of perceived mistreatment inevitability and the role of perpetrator power relative to the target in augmenting this relationship. I begin by developing and validating a psychometrically robust measure of perceived mistreatment inevitability. Next, I adopt a multi-method approach to test my proposed model across two studies: an online experiment and a time-lagged critical incident technique. The findings indicate that perceived mistreatment inevitability relates positively to observer evaluations of mistreatment legitimacy and negatively to evaluations of target legitimacy. In turn, these legitimacy evaluations have implications for observer reactions to the mistreatment incident and the target of mistreatment. Perceived mistreatment tolerance climate serves as an antecedent of perceived mistreatment inevitability. While I did not find support for the augmenting role of perpetrator power, findings from supplemental analyses revealed that females (but not males) may be disadvantaged as targets in climates characterized by perceived mistreatment tolerance. Taken together, these findings provide important theoretical implications including why observers may justify workplace mistreatment, how this can impact their behaviors, what may prompt observers’ system justification tendencies, and who is most likely to experience these detrimental effects. This research also provides practical insights into how to mitigate the effects of mistreatment in the workplace.
title: Grecian Urns and Tin Watermelons: Lyric, Truth and Beauty, with reference to Mark Doty, and comparisons with Philip Larkin
Creators: name: Daniels, Peter

description: Romantic poets such as Keats established lyric as poetry of the self and its apprehension of truth and beauty. These qualities were later questioned by modernists and postmodernists; they discouraged grand abstractions and complicated the position of the self, and the poetic category of lyric. I argue that despite this, the lyric self – embodied in the poem as performative act – remains an expression of the poet’s experiencing self, and together they form a three-way relationship with the reader. In my commentary, I begin by outlining my development as a queer Quaker poet, and affirm the role and significance of truth and beauty as key factors in my lyric poems. In chapters 2 and 3, I discuss the language and performativity of the lyric self, drawing on the poetry of Mark Doty and Philip Larkin, and works of lyric theory such as those by Jonathan Culler, Virginia Jackson and Yopie Prins, and Marion Thain. In chapter 4 I discuss how metaphor and metonymy rely on both difference and similarity for performative verbal description, which is rooted in the subjectivity of the lyric self. In chapter 5 I examine the performativity of the lyric and the queer self, and how queerness is a ‘making strange’ that can renew the power of truth and beauty. The queer angle to the heteronormative combines the irony of camp with the seriousness of fetish; it may also have a spiritual dimension. In chapter 6 I contemplate the truths of time and death, which are the limits of queer questioning. Lives have arbitrary beginnings and ends but aesthetic shaping gives meaning and drives the association of beauty and death. The poem will always have an ending, a paradigm of form givingmeaning to time, conveying an experience of truth and beauty.
