Sexuality, Relationships and Reproductive Choices in Young Adults with Life-Limiting and/or Life-Threatening Conditions
This thesis details an empirical exploration of how young adults with life-limiting and/or life-threatening conditions talk about sexuality, intimacy, relationships and reproductive choices; what these mean, the difficulties they encounter along an uncertain life course, their relationship experiences, and what would be helpful to assist and make their lives more meaningful.
The research centres on 13 young adults aged over 16 years, featuring some, but not all, life-limiting or life-threatening conditions. These include cystic fibrosis, duchenne muscular dystrophy, other progressive neuromuscular and rare conditions, certain cancers and other genetic conditions. The research also explores the views and contributions of family supporters: two partners, ten parents and ten care practitioners, seeking their views in order to advance the young adult’s sexual and relationship fulfilment. Until recently, surviving into adulthood with a life-limiting or life-threatening condition was unusual. Young adults with these conditions are a growing population and it is timely to explore their personal choices and considerations around sexuality, intimate relationships, and reproductive choices. The research used a qualitative approach, underpinned by a life course theoretical perspective, in conjunction with the illness experience and intersectionality with sexuality on an uncertain life course, to make sense of the participants’ varied and personal contributions. What emerged was a picture of the transitions which occur from childhood to adulthood, from comparative wellness to progressive illness, uncertainty about their life course and importantly, their sexuality.
The findings suggest that the voices of this group are insufficiently heard and that there is a gap in the provision of information with respect to their transition from childhood to adulthood, particularly in relation to their sexuality and reproductive choices. As this group strives for independence and sexual citizenship, efforts need to be congruent with and grounded in the views of those most personally involved, the young adults themselves
Corruption, Seigniorage and Growth: Theory and Evidence
This paper presents an analysis of the effect of bureaucratic corruption on economic growth through a public finance transmission channel. At the theoretical level, we develop a simple dynamic general equilibrium model in which financial intermediaries make portfolio decisions on behalf of agents, and bureaucrats collect tax revenues on behalf of the government. Corruption takes the form of the embezzlement of public funds, the effect of which is to increase the government’s reliance on seigniorage finance. This leads to an increase in inflation which, in turn, reduces capital accumulation and growth. At the empirical level, we use data on 82 countries over a 20-year period to test the predictions of our model. Taking proper account of the government’s budget constraint, we find strong evidence to support these predictions under different estimation strategies. Our results are robust to a wide range of sensitivity tests.corruption, seigniorage, inflation, growth
Exploring the fragile antiferromagnetic superconducting phase in CeCoIn5
CeCoIn5 is a heavy fermion Type-II superconductor which exhibits clear
indications of Pauli-limited superconductivity. A variety of measurements give
evidence for a transition at high magnetic fields inside the superconducting
state, when the field is applied either parallel to or perpendicular to the c
axis. When the field is perpendicular to the c axis, antiferromagnetic order is
observed on the high-field side of the transition, with a magnetic wavevector
of (q q 0.5), where q = 0.44 reciprocal lattice units. We show that this order
remains as the magnetic field is rotated out of the basal plane, but the
associated moment eventually disappears above 17 degrees, indicating that the
anomalies seen with the field parallel to the c axis are not related to this
magnetic order. We discuss the implications of this finding.Comment: Accepted Physical Review Letters, September 2010. 4 pages, 4 figure
Preclinical characterization of drug like glucocorticoid induced leucine zipper peptide analogs
poster abstractMany intermolecular interactions in a eukaryotic cell are mediated through protein-peptide interactions. For efficient interaction, the peptide scans the protein surface for a large enough pocket into which it anchors through a small number of residues/core motif that contribute maximally to the free energy of binding. Of special significance is the preponderance of proline rich sequences that preferentially adopt the left-handed polyproline type II (PPII) helical conformation in the interface peptides. Availability of both side chain and backbone carbonyls for interaction makes PPII helix an excellent recognition motif. Glucocorticoid induced leucine zipper (GILZ), is a glucocorticoid responsive protein that has been shown to suppress immuno-inflammatory responses by preventing the nuclear translocation of the p65 subunit of the transcription factor nuclear factor-kappa B (NF-ÎşB). Mutational and binding studies localized the sites of interaction to the proline rich region at the carboxy terminus of GILZ and the transactivation domain of p65. Similar to most intermolecular interactions mediated by proline rich motifs the strength of interaction between the GILZ and the p65 proteins is in the micromolar concentration suggesting weak binding kinetics. A widely used strategy in the discovery of peptide drugs involves exploitation of the complementary surfaces of the naturally occurring binding partners. We observed that a synthetic peptide (GILZ-P) derived from the proline rich region of GILZ suppressed immune mediated inflammatory responses in mice. Here we characterize GILZ-P structurally and evaluate its toxicity and efficacy in mature human macrophage like THP-1 cells. We show that the GILZ-P adopts an extended polyproline type II helical conformation. Functionally GILZ-P is non-toxic, suppresses NF B activation on by activated macrophages suggesting a therapeutic potential in pathologies wherein persistent inflammation plays critical role in the disease initiation and/or progression

Canary in the coal mine: Lessons from the Jarrah Forest suggest long-term negative effects of phosphorus fertilizer on biodiverse restoration after surface mining
Despite nutrient enrichment having widely reported negative impacts on biodiversity, fertilizer is routinely applied in post mining restoration to enhance plant growth and establishment. Focusing on surface mine restoration (predominately bauxite and mineral sands), we outline the long-term negative impacts of fertilizer, particularly phosphorus fertilizer, on plant community composition, species richness, fire fuel loads, and belowground impacts on nutrient-cycling. We draw from extensive research in south-western Australia and further afield, noting the geographical coincidence of surface mining, phosphorus impoverished soil and high plant biodiversity. We highlight the trade-offs between rapid plant-growth under fertilisation and the longer-term effects on plant communities and diversity. We note that the initial growth benefits of fertilisation may not persist in water-limited environments: growth of unfertilised forests can eventually match that of fertilised forest, throwing doubt on the premise that fertilisation is necessary at all
