Table_1_Genome-Wide Association Study Reveals Complex Genetic Architecture of Cadmium and Mercury Accumulation and Tolerance Traits in Medicago truncatula.xlsx
No full textHeavy metals are an increasing problem due to contamination from human sources that and can enter the food chain by being taken up by plants. Understanding the genetic basis of accumulation and tolerance in plants is important for reducing the uptake of toxic metals in crops and crop relatives, as well as for removing heavy metals from soils by means of phytoremediation. Following exposure of Medicago truncatula seedlings to cadmium (Cd) and mercury (Hg), we conducted a genome-wide association study using relative root growth (RRG) and leaf accumulation measurements. Cd and Hg accumulation and RRG had heritability ranging 0.44 – 0.72 indicating high genetic diversity for these traits. The Cd and Hg trait associations were broadly distributed throughout the genome, indicated the traits are polygenic and involve several quantitative loci. For all traits, candidate genes included several membrane associated ATP-binding cassette transporters, P-type ATPase transporters, oxidative stress response genes, and stress related UDP-glycosyltransferases. The P-type ATPase transporters and ATP-binding cassette protein-families have roles in vacuole transport of heavy metals, and our findings support their wide use in physiological plant responses to heavy metals and abiotic stresses. We also found associations between Cd RRG with the genes CAX3 and PDR3, two linked adjacent genes, and leaf accumulation of Hg associated with the genes NRAMP6 and CAX9. When plant genotypes with the most extreme phenotypes were compared, we found significant divergence in genomic regions using population genomics methods that contained metal transport and stress response gene ontologies. Several of these genomic regions show high linkage disequilibrium (LD) among candidate genes suggesting they have evolved together. Minor allele frequency (MAF) and effect size of the most significant SNPs was negatively correlated with large effect alleles being most rare. This is consistent with purifying selection against alleles that increase toxicity and abiotic stress. Conversely, the alleles with large affect that had higher frequencies that were associated with the exclusion of Cd and Hg. Overall, macroevolutionary conservation of heavy metal and stress response genes is important for improvement of forage crops by harnessing wild genetic variants in gene banks such as the Medicago HapMap collection.</p
Modelling visitor experience: a case study from World Heritage Sites, Thailand.
No full textThe subject of this Ph.D. Thesis is Modelling Visitor Experience: A Case Study from World Heritage Sites, Thailand. The research is conducted in three historical parks in Thailand by using an inductive approach of Grounded Theory. This aims to propose a model of visitor experience of heritage. It focuses on experience consumption related to what, why and how visitors consume the heritage experience when they interact with the cultural heritage. The construction of experience, factors affecting experience consumption and patterns of experience consumption are explored in this thesis. It provides theoretical and methodological contribution to the knowledge in both tourism and management fields.
The opportunity to collect data for this study stems from the three historical sites in Thailand by which grounded theory approach allows for a wider variety of data collection methods. The research had been conducted in the historical sites for over six months during October 2003 March 2004. The results presented in this thesis are based on a survey of 60 cases of participant observations with ethnographic interview and 180 cases of observation with visitors visiting the historical sites, and 48 unstructured and semi-structured interviews with visitors who visited those sites. The results are also based on a number of supplementary data such as travel journals, visitor books, and interpreted photographs written and taken by visitors who visited to the sites. Survey instruments for this study consist of interview and observation guides that were developed accordingly to emergent concepts during the field survey. The contributions comprise four major themes. Firstly, the development of the 'Visitor Heritage
Experience Model' based on multiple sources of data conceptualised by a systematic analysis process. The model provides the insight of visitors' subjective interactions with the heritage when they were engaged in a consumption of experience. This study reveals the multi-dimensional nature of visitor experience which expands what has been reported in the literatures. It also explains the complex attributes of visitors' on-site experience in terms of process and components of experience construction. Secondly, the emergent of 'Interactive Experience Process' as a core of the proposed model, acknowledges the dynamic nature of on-site experience through a multi-phase experience process and multiplicity of visitors' experience consumption practices. Rather than acknowledging
the tourist typology, this study explores the extent to which the elements of experience hold in different contexts and types of consumption experiences. The emergent theory can be used as a substantive theory to apply for other case studies involving visitors' experience of place. Thirdly,
the findings of this study have significant implications for designing principles and practices of an effective and sustainable visitor management in cultural heritage sites. The development of the, Visitor Experience Management Framework' discusses the creative use of the heritage and visitor empowerment to provide interactive experience of heritage to visitors. It suggests the consideration of a paradigm shift and crucial elements of visitor experience management especially in sensitive cultural heritage sites. Finally, this study provides several conceptual and methodological research perspectives through the use of 'Grounded Theory Approach'. The applications of the grounded theory's systematic analysis process can be adopted by future consumer and management research
Cello techniques and performing practices in the nineteenth and early twentieth centuries
No full textThis thesis comprises a study of cello performance practices throughout the nineteenth century and into the early decades of the twentieth. It is organised in terms of the increasing complexity of the concepts which it examines, as they are to be found in printed and manuscript music, instrumental methods and larger treatises, early recordings, concert reviews and pictures. Basic posture is considered along with different ways of holding the
bow. The development of the tail-pin shows that even when it was widely used, the older posture was still referred to as a model. Some implications for tone quality and tonal
projection are considered in the light of the shape of the arms. Some connections between the cellist's posture and that recommended by etiquette books are explored. The
functionality of the left hand and arm, and the development of modem scale fingerings, show that there was a considerable period of overlap between newer and older practices, with modern scale fingerings evolving over a long period of time. Similarly, views on the function of the right wrist in bowing are shown to change gradually, moving towards a more active upper arm movement with less extreme flexibility of the wrist. Two central expressive techniques especially associated with string playing arc considered in the context of the cello, namely vibrato and portamento. These topics are examined in the light of written indications in music, recommendations in cello treatises, and the practices evidenced in early recordings. The sources for this study can be brought into an overall
framework of a constant dialogue between `theory', as expressed in verbal instructions to the learner, or general a priori reflections about the cello, and `practice', manifested in performing editions and early recordings, or in individual acts of reception. A wide divergence is noted, both between theory and practice in general, and in terms of different styles of playing observable at any one time. It is suggested that tensions between practice
and critical disapproval can be resolved in terms of Lacanian discourse. Several test cases are used in order to compare several different recordings of the same works. The question of the musical character of the cello is discussed in terms of widespread assumptions about its gendered identity. A wide range of sources suggest that this moved from a straightforwardly `masculine' identity expressed through a controlling, elevated eloquence to a less clearly defined one, incorporating the 'feminine', with a greater stress on uninhibited emotional expression. Some performance implications for this change of view are pursued with respect to specific repertoires. Broad conclusions stress the importance of the diversity of performance practices as opposed to unifying generalisations

The Value of Gluten-Free Attributes in Snack Foods
No full textabstract: Celiac Disease (CD) is now widespread as one in 133 people are currently diagnosed, while there were only one in 150 in 2006. Much of the research concerning CD is still in the early stages, as formal epidemiological studies are relatively recent. CD is aggravated by the consumption of gluten, which is found mainly in wheat, rye, oats, and barley. Not surprisingly, the rising prevalence of CD has created a significant business opportunity for food manufacturers in developing products that are tailored to CD sufferers. While the entire Gluten-Free (GF) industry has been experiencing double digit growth rates, the expansion in available snack foods has outstripped all others. Observation of GF snack food prices suggests that food manufacturers are responding to high retail prices associated with GF foods. However, GF foods are often also advertised with other attributes that generally sell for a premium over conventional foods. Therefore, whether the high retail price for GF snack foods can be attributed specifically to the GF attribute is an empirical question. The objective of this research is to determine whether there is a retail-price premium for GF snack foods and, if there is, to estimate its magnitude. A hedonic pricing model is used to answer this question. Specifically, a hedonic pricing model was applied to a unique dataset of snack food products in order to estimate the marginal value for the GF attribute, while controlling for a number of other important attributes. Results show that the GF attribute is both economically and statistically significant, implying a premium of nearly 0.50 (assuming 40% margins). However, high premiums may not last as large retailers are utilizing their influence over suppliers to keep retail margins low. Therefore, the primary implication of the research is that the rapid growth in recent years can easily be explained on economic grounds for large agribusinesses, as this implies a major profit opportunity.Dissertation/ThesisM.S.

Taxonomy, phylogenetic and biogeographical relationships of African grassland Francolins (Genus: Scleroptila)
No full textBibliography: leaves 23-28.The potential for using a combination of molecular and whole-organismal data has opened up new avenues for avian taxonomy, phylogenetics and biogeography. Such a multifaceted approach is used here to identify diagnosable taxa within the Orange River Francolin Scleroptila levaillanloides species complex and resolve evolutionary relationships between these taxa and other mono-and polytypic forms within the Red-winged Group of francolins (= genus Scleroplila sensli lalo). Mitochondrial cytochrome-b DNA sequence data (±250 b.p.) from 50 individuals and 19 morphological characters extracted from reports in published literature were employed to achieve these aims. These characters were analysed separately and also in combination using maximum parsimony (DNA sequences and organismal data), maximum likelihood (DNA sequences) and distance (DNA sequences) analyses. Monophyly of the Red-winged Group plus the Ring-necked Francolin Dendroperdix slreptophorus was supported by all the analyses (bootstrap support ranged from 50%-94%) except distance analysis. The Orange River Francolin complex was found to be non-monophyletic. Two distinct clades were identified, one comprising taxa from southwestern and the other from northeastern Africa. Morphological analysis yielded a distinct clade of the southwestern Orange River Francolin. The other polytypic species and assemblages thereof show poor resolution. The results of this study clearly demonstrate a need for further assessment of the taxonomic status of Scleroptila spp. and their phylogenetic relationships
Benefits and costs of international financial integration : theory and facts
No full textThe author provides a selective review of the recent analytical and empirical literature on the benefits and costs of international financial integration. He discusses the impact of financial openness on consumption, investment, and growth, and the impact of foreign bank entry on the domestic financial system. Consistent with some recent studies, the author argues that financial integration must be carefully prepared and managed to ensure that the benefits outweigh the short-run risks. Prudent macroeconomic management, adequate supervision and prudential regulation of the financial system, greater transparency, and improved capacity to manage risk in the private sector are important requirements for coping with potentially abrupt reversals in pro-cyclical, short-term capital flows. The author adopts a more skeptical view than some assessments in two areas, however. First, only foreign direct investment appears to provide dynamic gains and improved prospects for growth; the evidence on the benefits of other types of capital flows remains weak. Second, empirical research on the net benefits associated with foreign bank penetration is far from conclusive; in particular, the possibility that such penetration may lead to adverse changes in the allocation of credit among domestic firms cannot be dismissed on the basis of the existing evidence.Banks&Banking Reform,Capital Markets and Capital Flows,Fiscal&Monetary Policy,Economic Theory&Research,International Terrorism&Counterterrorism,Economic Theory&Research,Banks&Banking Reform,Macroeconomic Management,Environmental Economics&Policies,Financial Intermediation
Rehearsing Reality: An Interactive Docufragmentary Exploration of the Theatre of the Oppressed's Engagement with the Brazilian Landless Movement (MST)
No full textThis thesis explores the Theatre of the Oppressed's practices at the point of interaction with peasants of Brazil's Landless Movement. It uses the interactive docufragmentary entitled Rehearsing Reality to explore the social and political role of art, and to ask whether particular applications of theatre and film can be used to understand and possibly transform points of view and raise consciousness about contemporary issues in the world.
The Theatre of the Oppressed created by Augusto Boal comprises a series of interactive games, exercises and other theatrical methods developed with the purpose of using these drama techniques as a subjective medium contributing both to question and search alternatives for personal and social problems. Amongst its theatrical methods is Forum Theatre, the main practice adopted by Brazil's Landless Movement. This technique breaks with the conventions of the traditional language of theatre. Its main aim is to transform passive audiences into active participants of a theatrical scene. This thesis argues that Forum Theatre is an open medium that offers people the chance to participate democratically in the theatrical space in order to suggest and rehearse new ideas to be applied into their lives.
In order to explore how these theatrical experiences work in practice this thesis includes a central element entitled Rehearsing Reality, which is specifically designed to adapt some of the main features from Forum Theatre to film language. Its aim is to activate viewers to interact with the film process. This thesis also explores the historical developments of the Theatre of the Oppressed with major emphasis on Forum Theatre and its practices amongst members of Brazil's Landless Movement living in camps and settlements in the hinterland of Sergipe State, North-East of Brazil.
The structure of the thesis is divided into five parts: Chapter One analyses the relevant literature on the subject; Chapter Two provides a reflective account of the filming period; Chapter Three offers an overview of Boal' s life and the development of the Theatre of the Oppressed methods; Chapter Four briefly looks at the history and development of the Brazilian Landless Movement and provides a practical analysis of the experiences of Theatre of the Oppressed amongst the Landless Movement and Chapter Five analyses the creative process of making the docufragmentary Rehearsing Reality. The Conclusion suggests that the social and political aspect of art can significantly contribute to the process of comprehension and transformation of the world
