The foraging behaviour of hummingbirds through space and time
No full textCentral place foragers, such as territorial hummingbirds, feed from resources that tend to be constant in space and to replenish with time (e.g. nectar in flowers). The ability to remember both where and when resources are available would allow these animals to forage efficiently. Animals that feed at multiple locations would also benefit from forming routes between these multiple locations. Hummingbirds are thought to forage by repeating the order in which they visit several locations following a route called a “trapline”, although there are no quantitative data describing this behaviour. As a first step to determining how and if wild free living hummingbirds forage by traplining, I decomposed this behaviour into some of its key components. Through five field experiments, where I trained free-living hummingbirds to feed from artificial flowers, I confirmed that territorial hummingbirds will, in fact, trapline. Birds will use the shortest routes to visit several locations and will prioritize those locations that are closest to a usual feeding site. Additionally, even though hummingbirds can learn to use temporal information when visiting several patches of flowers, the spatial location of those patches has a larger influence in how these birds forage in the wild. Since male and female hummingbirds were thought to forage differently I also tested whether there were sex differences in the types of cues they use when foraging. Contrary to expectation, female hummingbirds will also use spatial cues to relocate a rewarded site. Using the foraging ecology of rufous hummingbirds to formulate predictions as to what information these birds should use has lead me to discover that these birds forage in a completely different way than previously thought

A detailed exploration of the organisation of home birth services in The Netherlands, towards knowledge transition and development of home birth services in N. Ireland:EU COST Action (IS1405) STSM Report
No full textAs part of the EU COST Action IS1405 'Building Intrapartum Research Through Health – an interdisciplinary whole system approach to understanding and contextualising physiological labour and birth (BIRTH)' this Short Term Scientific Mission (STSM) was undertaken by Dr Maria Healy from 5th Sept to 9th Sept 2016. This STSM to The Netherlands has been invaluable in relation to gaining knowledge of the Dutch maternity care system and provision of home birth care. This knowledge will enhance the development of the proposed regional evidenced-based guideline for planning birth at home in Northern Ireland. An application for funding has already been forwarded to the RIQA’s, GAIN (Guideline Audit and Implementation Network) in early October 2016
The Life and Afterlives of Patrick Francis Healy, S.J.
No full textabstract: This dissertation centers on the life of Patrick Francis Healy, the son of an enslaved woman and an Irish slaveholder. Born in 1834, Healy became a Jesuit priest in 1864 and the president of Georgetown University in 1874, seven decades before Georgetown admitted its first African American student. In the twentieth century, historical investigations of race and American Catholicism cast Healy and his family in a new light. Today, the Healys are upheld in some circles as African American Catholic icons. Patrick Healy is now remembered as the first African American Jesuit and Catholic university president, as well as the first African American to receive a doctorate. This dissertation pursues both the life of Patrick Healy as well as what I call his “afterlives,” or the ways in which he has been remembered since the 1950s, when Albert S. Foley, S.J. discovered that the Healys’ mother was enslaved and refashioned them from white Irish Americans to white-passing African Americans. How and why did Patrick Francis Healy understand and comport himself as a white, upper-class Catholic? How and why have others sought to construct him as African American in the years since his ancestry was made widely known? How has Georgetown incorporated Healy’s legacy, in the context of its and other universities’ coming-to-terms with their dealings with slavery more broadly? I pursue these questions through archival sources (primarily Healy’s diaries and letters) at Georgetown University and College of the Holy Cross, as well as secondary literature on passing, subjectivity, and hagiography.Dissertation/ThesisDoctoral Dissertation Religious Studies 202
Conclusions
No full textThe authors draw conclusions from the analysis carried out in the book, based on the reflections and outcomes achieved in the project ‘Close the Deal, Fill the Gap’, focused on the way that pay is ordered and structured in the three countries, Italy, Poland and UK, and in different sectors within those countries to enable a wider understanding of the GPG from the perspective of two contradictory forces: the arguably centralised EU imperative to reduce the GPG against the alternative impera- tive for increasingly decentralised collective bargaining and industrial rela- tions
Memory in the Novels by Dermot Healy
No full textEnglish title and keywords: Memory in the Novels by Dermot Healy - Dermot Healy, Irish literature, Irish novel, memory, collective memory Despite his large and diverse body of work Irish writer Dermot Healy remains somewhat ignored by scholars. However, his formally diverse writing which spans from novels and short stories to poetry and dramatic work is without a doubt worthy of critical response. One of Healy's themes is an engagement with the formation of memory and with how an experience transforms in the mind of its 'experiencer' and changes into what from a certain perspective may be regarded as fiction. Stemming from his own life experiences the author engages a topic common to all human beings and plays with the concept of memory and its possible distortion in his autobiography The Bend For Home (1996), as well as in his plays and poems. His autobiographic work can be seen as a background for the theme; however, the present thesis will focus on Healy's novels, starting with Fighting with Shadows (1984) through A Goat's Song (1994), Sudden Times (1999) to his final novel Long Time, No See (2011). In these books and in the characters that Healy presents we are able to observe individuals with diverse personal histories who return to individual experienced events through reconstruction and in..
A study of the role of metal salts in the synthesis of macrocycles from the condensations of furan with some carbonyl compounds
No full textThe acid catalysed condensation of furan with acetone was performed in i the presence of some alkali, alkaline earth and transition metal salts.The yield of a furan-acetone cyclic tetramer, C2883204, was considerably enhanced in comparison to the reactions with non-metal salts and with no added salts. Initially, the metal ions were believed to be participating in a template capacity. This condensation system was studied by systematically changing each parameter. The action of the salts was found torelate to changes in the acidity of the reaction media rather than to a k specific template action. From the furan-acetone condensation were isolated several oligomers which were further reacted to obtain macro-cycles. Lithium perchlorate was also used in the condensation of furan with some aliphatic, alicyclic, aromatic and functional ketones as well as formaldehyde and acetaldehyde. In most cases macrocylic tetramers were isolated with much improved yields compared to reactions with no added metal salts. A furan-cyclohexanone macrocycle was prepared for the first time by a one step reaction. Similarly, some B-substituted furans were condensed with acetone but no macrocyclic products were obtained. Several reactions including formylation and bromination were carried out on the furan-acetone cyclic tetramer. Both the cyclic tetramer and hexamer were hydrogenated to give the tetrahydrofuran macrocycles. The ability of these macrocycles to complex a variety of cation were tested by n.m.r. spectroscopy. The tetrahydrofuran-acetone cyclic tetramer was found to specifically complex Li+ to the exclusion of other cation and a 1:1 complex with LiC1O4 could be isolated. The tetrahydrofuran-acetone cyclic hexamer was found to weakly complex Cs+.</p
