Urban Farming in Atlanta, Georgia: The Seed of Neoliberal Contestation or Hybridized Compromise?

The space on which the urban farm is produced has a history of its own that can be explored for evidence of neoliberal shaping and retooling. This thesis explores how the city and the farm are understood through the complex articulations of farmers and through the account of the specific historical and geographical context of the farm. The urban farm is a uniquely situated land use that can provide the spaces for contestation to the neoliberalization of the city and the United States food system. Through qualitative analysis, including a case study, interviews with farmers, participant observation, and archival data collection, this research examines the city and the farm from the perspective of the farmer to understand the degree to which these contestations are resisting neoliberalism. Furthermore, it suggests that scholars of neoliberalism and urban farming should more fully consider the hybridized nature in which urban farmers understand their work

Ligand Effects on (De)hydrogenative Catalysis using the RPNR’P Pincer Scaffold

This thesis summarizes synthetic, catalytic, and mechanistic work towards improved understanding of steric and electronic ligand effects in systems supported by the frequently used RPNR’P (RPNR’P = R’N(CH2CH2PR2)2) pincer ligand. Chapter 1 provides an overview of previous work on the synthetic and catalytic effects of varying the substituents of the RPNR’P ligand or other ancillary ligands. Chapter 2 describes the synthesis and catalytic activity of a series of novel iPrPNMeP iron isonitrile complexes to investigate the role of the π-acid ligand. In chapter 3, an active and productive additive-free formic acid dehydrogenation system is developed and optimized using an iron iPrPNMeP catalyst. Chapter 4 discusses the synthesis of a new N-phenyl ligand iPrPNPhP and its coordination to ruthenium, followed by a detailed catalytic and mechanistic comparison between iPrPNR’P ruthenium complexes which differ only in their N-substitution. In chapter 5, the synthesis and characterization of a series of base metal iPrPNPhP complexes is described

A search for distant radio galaxies from SUMSS and NVSS: II. Optical Spectroscopy

This is the second in a series of papers presenting observations and results for a sample of 76 ultra-steep-spectrum (USS) radio sources in the southern hemisphere designed to find galaxies at high redshift. Here we focus on the optical spectroscopy program for 53 galaxies in the sample. We report 35 spectroscopic redshifts, based on observations with the Very Large Telescope (VLT), the New Technology Telescope (NTT) and the Australian National University's 2.3m telescope; they include five radio galaxies with z>3. Spectroscopic redshifts for the remaining 18 galaxies could not be confirmed: three are occulted by Galactic stars, eight show continuum emission but no discernible spectral lines, whilst the remaining seven galaxies are undetected in medium-deep VLT integrations. The latter are either at very high redshift (z >~7) or heavily obscured by dust. A discussion of the efficiency of the USS technique is presented. Based on the similar space density of z>3 radio galaxies in our sample compared with other USS-selected samples, we argue that USS selection at 843-1400 MHz is an efficient and reliable technique for finding distant radio galaxies.Comment: 15 Pages including 49 PostScript figures.

The nature and role of music in NŌ - with special reference to the play, Hagoromo

Little has been written in Western languages on the music of No beyond its brief mention in t he increasingly large volume of literature on o~her aspects of the drama. Japanese sources, however, include, besides works containing descriptions of a general nature, detailed instruction books that exist for the majority of schools of instrumental and vocal music, and these have over the past two decades been supplemented by excellent musicological studies by a limited number of Japanese authorities. The present study is an attempt at a detailed examination and description of the nature of the music and its role in this unique theatrical genre. The present study is divided int o two parts. Part I (chapters I to IV) begins with a general description of No music and its components. It goes on to describe in detail the vocal and instrumental music and their I functioning as an ensemble. In the process an attempt is made to show the theoretical basis and concept o f the music. Part II (chapters V-VIII) is an examination of the actual operation of the music in the play. It begins with a general exposition of the typical structure o f a No play. This is followed by a 'score' of the well-known No play, Hagoromo , in which the notation of each of the four instruments is set down alongside a romanized version of the Japanese text. The work concludes with a description of the music of that play through which an attempt is made to establish the precise role of music in No and its contribution to the drama

Vaccination of foals with a modified live, equid herpesvirus-1 gM deletion mutant (RacHΔgM) confers partial protection against infection

Equid herpesvirus-1 (EHV-1) causes respiratory and neurological disease and late gestation abortion in pregnant mares. Current vaccines contain either inactivated or live EHV-1, but fail to provide complete clinical or virological protection, namely prevention of nasopharyngeal shedding and cell-associated viraemia. Thus, the development of novel products, such as modified live virus (MLV) vaccines which stimulate virus-specific, humoral and cell mediated immune responses more effectively remains a priority. Two groups of weaned foals (n = 6 each group) were used in a longitudinal, prospective, experimental study to evaluate immune responses elicited by two vaccinations with a glycoprotein M (gM) deletion mutant of EHV-1 (RacHdeltagM). Following two concurrent intranasal and intramuscular inoculations six weeks apart, vaccinated (8.4 ± 0.2 months old) and control foals (6.2 ± 0.4 months) were challenge infected intranasally with EHV-1 Ab4/8 four weeks after the second vaccination and clinical signs and virological replication measured. Vaccination caused no adverse events, but did stimulate significantly higher complement fixing and virus neutralizing antibodies in serum compared with control foals at either equivalent or pre-vaccination time points. Virus-specific nasopharyngeal antibody levels and cytotoxic T lymphocyte responses were not significantly different between the groups. Following challenge infection, these immune responses were associated with a reduction in clinical signs and virological replication in the vaccinated foals, including a reduction in duration and magnitude of pyrexia, nasopharyngeal shedding and cell-associated viraemia. We conclude that the RacHΔgM MLV primed EHV-1-specific humoral immune responses in weaned foals. However, complete virological protection by vaccination against EHV-1 requires further research

A Systematic Review of Psychometric Properties of Health-Related Quality-of-Life and Symptom Instruments in Adult Acute Leukemia Survivors

Acute leukemia represents 4% of cancer cases in the United States (US) annually. There are over 302,000 people living with acute and chronic leukemia in the US. Treatment has been shown to have both positive and negative effects on health-related quality of life (HRQOL)

Towards Water Soluble Mitochondria-Targeting Theranostic Osmium(II) Triazole-Based Complexes

The complex [Os(btzpy)2][PF6]2 (1, btzpy = 2,6-bis(1-phenyl-1,2,3-triazol-4-yl)pyridine) has been prepared and characterised. Complex 1 exhibits phosphorescence (λem = 595 nm, τ = 937 ns, φem = 9.3% in degassed acetonitrile) in contrast to its known ruthenium(II) analogue, which is non-emissive at room temperature. The complex undergoes significant oxygen-dependent quenching of emission with a 43-fold reduction in luminescence intensity between degassed and aerated acetonitrile solutions, indicating its potential to act as a singlet oxygen sensitiser. Complex 1 underwent counterion metathesis to yield [Os(btzpy)2]Cl2 (1 Cl), which shows near identical optical absorption and emission spectra to those of 1. Direct measurement of the yield of singlet oxygen sensitised by 1 Cl was carried out (φ ( 1O2) = 57%) for air equilibrated acetonitrile solutions. On the basis of these photophysical properties, preliminary cellular uptake and luminescence microscopy imaging studies were conducted. Complex 1 Cl readily entered the cancer cell lines HeLa and U2OS with mitochondrial staining seen and intense emission allowing for imaging at concentrations as low as 1 µM. Long-term toxicity results indicate low toxicity in HeLa cells with LD50 >100 µM. Osmium(II) complexes based on 1 therefore present an excellent platform for the development of novel theranostic agents for anticancer activity

Elite coaches’ use and engagement with performance analysis within Olympic and Paralympic sport

The use and implementation of performance analysis and feedback by 18 elite Olympic/Paralympic coaches (coaching experience 16.1 ± 7.4; experience using performance analysis 8.3 ± 4.8 years) was explored via an online questionnaire (mean time to complete = 29 minutes). Likert scales were used to facilitate cross-sport comparison. Comment boxes were included to enable additional information to be provided if deemed necessary. Training goals, athlete discussion and coaching philosophy were the most prominent features influencing analysis direction. Time available had the greatest impact upon feedback provision. The main analysis techniques used were video, performance reports, and trend analysis. Coaches with greater experience delivered significantly more feedback sessions within 1-hour of performance. Feedback sessions were < 20-minutes in duration and delivered in a balanced (experienced) or mostly positive (inexperienced) approach. Feedback was delivered consistently according to a preferred schedule, face-to-face, and within an individual format. Sessions were usually coach led, however considerable value in a combined or analyst led approach was demonstrated. The findings have begun to illustrate practice within elite sport from the perspective of a key user of performance analysis, i.e. the coach, and have clear implications for practitioners by identifying the key areas coaches’ value from performance analysis
