Abstract:

I have always approached my paintings with confidence. Mark making has always been my strength, particularly in drawing, and I feel this comes through in my gestural use of the paint. I also believe I approach paintings in a trial and error manner, where experimentation has precedence over concept. To remain in the moment and focused on what I am doing at that moment is a fundamental base of both my process and, interestingly what the resulting image translates to the viewer. To know this, and to remain suspended in this moment requires a foundation of trust within my capabilities and myself. Approaching each new surface, I test various methods of applying paint. The successful methods prove to be ones that allow me to continuously build the surface into a coherent image. These methods I choose from, sometimes in sequences, as obstructions, or as starting points. In each painting, I begin differently, even if it is just a different colored ground. I have found the most success in starting with a specific method, one that exists in isolation, as a starting point. I believe that too often, I look for answers outside myself instead of looking within. I do not seek a linear trajectory for painting, and my own work, though ironically specific to its medium, should not be categorized into a neat package. If my brush is an extension of myself, then what I think and feel comes through as my own thoughts and feelings.

Lacey, M. E. R. "Birds and bird-lore in the literature of Anglo-Saxon England." Thesis, University College London (University of London), 2014. http://discovery.ucl.ac.uk/1431318/.

Full text

Abstract:

This thesis presents an interdisciplinary approach towards understanding the ways in which Anglo-Saxons perceived the birds around them and the cultural associations with which we find them endowed in the literature. It focuses on closely examining the entire range of primary sources available to us in order to build as accurate and as complete a picture of Anglo-Saxon bird-lore as possible, and it stresses the indivisibility of observational experiences of birds and their cultural associations. As very little work has been done on birds in Old English, this thesis starts with the fundamentals: how were birds categorised, identified and differentiated? Such fundamental questions must be addressed if we are not to anachronistically impose our own understanding on the Old English evidence. My examination reveals that birds were primarily heard, rather than seen, and that this experience of birds is reflected in the literature, where descriptions focus on their calls, instead of their appearances. This aural primacy is stressed throughout the thesis. In the first half of the thesis I argue for remnants of an apparently ancient, and common Germanic, practice of augury in the literature of Anglo-Saxon England, in which the vocalisations of birds were held to contain prophecies and tidings of present import. I present arguments for this belief being grounded in observed experience, stressing the connection between bird-lore and the lived experiences of birds in the Anglo-Saxons’ environment. In the second half of the thesis, I demonstrate that Christian bird-lore was quite different, being steeped in symbolism and scholarly tradition rather than naturalistic observation, but that it had common ground in associating birds with divine knowledge. I subsequently show how the Christian traditions of birds interacted with pre-Christian bird-lore – both in terms of augury and in terms of Anglo-Saxon proto-scientific classification.

Stearns, Danielle Marie 1969. "Bird abundance as an indicator of habitat quality for breeding birds." Thesis, The University of Arizona, 1995. http://hdl.handle.net/10150/278475.

Full text

Abstract:

Reproductive success and survival of birds often are impractical to measure. Therefore, biologists frequently rely on measures of bird abundance alone to evaluate habitat quality for breeding birds. I examined whether results from standard survey techniques for birds during the breeding season reflected number of nesting pairs and reproductive success of 5 passerine species. Abundance of 3 species was positively associated with number of nesting pairs, but the relationship between abundance and reproductive success varied among these species. Differences in detectability of breeding males may partly explain why abundance and number of nesting pairs were related in some species and not in others. Variations in the availability and quality of habitat patches among plots could produce the different relationships I observed between abundance and reproductive success. My results suggest that measures of reproductive success as well as abundance should be used to determine habitat quality for breeding birds.

Abstract:

This novella is made up of interlinked stories from a rural township in the North West province. The stories of this surface-tranquil place are told through descriptive passages, vignettes, snatches of dialogue, profiles and picture-postcards, all organically interwoven and entwined, and rendered in non-linear fashion. They are set in shebeens, shops, farmlands and the dusty empty spaces of the South African landscape, peopled by police, tourists, and prostitutes of all sorts. The pervasiveness of violence in all forms has the fictional narrator reflecting on the violence of his own past. A smattering of musicians' musings gleaned from interviews and album liner-notes helps him navigate his way through this morass, the rage and frustration that simmers beneath it all.

Abstract:

The interest in birds has had a rapid increase since the 1800 century. Nowadays the interest is especially big in the US and UK. The aim of this study was to see if the interest in birds followed the same pattern here in Sweden, as well as to see why people get interested in birds to begin with. To answer the purposes of the study, questionnaires were handed out to people in the age of ten and older. Along with to see how many people were interested in birds, the purpose of the questionnaire was to see whom is interested in birds and if birds had any special meaning to the participants. The study indicated that the interest followed the same path here in Sweden as in the US and UK. Women were more interested in birds than men and the interest increased with age. The average bird enthusiast was a woman between 45 and 54 years old. However one can’t wholly tell why people are interested in birds, since the interest in birds lies within the people themselves. One can though say that birds and birding have physical and psychological health benefits, which could be a reason for their allure.

Abstract:

The major human activities that have transformed the Earth include agriculture and urbanization. The present study was conducted to contribute to a description of the effect on birds of urbanization and agriculture in an Indian region. Terrestrial bird assemblages were censused along a five-stage urbanisation gradient between January and April 2010-2013 near the city of Amravati, on the Deccan Plateau, Central India. Altogether, 89 species of birds were recorded, with the highest species richness in the rural areas (67 species) and lowest in the urban stage (29 species). The assemblages were significantly nested in all the five stages. Maximum cumulative species abundance (12 399 individuals over four years) was found in the urban stage, and was due to the constant presence of large groups of Rose-ringed Parakeets (Psittacula krameri). The lowest bird abundance was found in the industrial zone (4837 in total), where there was also a nearly two-fold decrease from 2010 to 2013. Thirty-six species demonstrated significant variation in their densities at least in one stage and between at least two months (p<0.05). Densities of 13.9% (n=5) of those species varied significantly in two stages, that of Copsychus saularis in three stages, and of Phoenicurus ochruros, in all five stages. Urban, suburban, periurban and forest stages were characterised by relatively stable species densities (significant changes observed only for 17.2% (n=5), 17.1% (n=6), 12.9% (n=7), and 17.8% (n=16) species, respectively). The additive diversity partitioning indicated that of the overall diversity (gamma-diversity), alpha diversity (within transects located within one stage) contributed 50.1% to the total diversity, and the controbution of within-stage variability was small (2.7%). Additionally, censuses on cultivated fields were taken. In two areas under mixed cropping systems, 53 bird species were identified in the two years period between June and December, 2011 and 2012. Out of the 53 detected species, only 14 were common (recorded at ≥50% of visits). Twenty-one species were recorded at Zadgaon in crops of tur (Cajanus cajan), cotton (Gossypium arboreum) and soybean (Glycine max). Nineteen species were recorded at Bhankhed in jawar (Sorghum bicolor), cotton and mung bean (Phaseolus aureus). At Zadgaon, territorial activity was observed in four species: the House Sparrow (Passer domesticus), Jungle Babbler (Turdoides striata), Yellow-eyed Babbler (Chrysomma sinense) and Red-wattled Lapwing (Vanellus indicus). The study indicated that four bird species were found under high risk, thirteen species at medium risk and eight species at low risk due to pesticide applications in croplands. The extent of crop damage in fields of groundnut, pearl millet, peas, sorghum, and sunflower was assessed by doing actual field censuses. The sustainable solution for reducing crop damage is a need for the farmers and such techniques will help to avoid direct or indirect effects of use of lethal bird control techniques on bird species diversity.

Abstract:

This report describes in detail the working process of constructing a normalized relational database with an associated graphical user interface, based on raw data data sets in CSV-format acquired from the Avian Knowledge Network. The data files contained the bird sightings from the year 2009 in North America. An entity-relationship model of the database was designed, including a table representing the raw data as well as tables representing the corresponding normalized relational data. As a first step the bulk loading facility of the DBMS is used for loading a CSV file into the raw data table. Then a SQL stored procedure is used for populating the final relational tables by transforming and cleaning the rows of the raw data table. Performance measurements were made about the data transformation as well as a comparison between querying the raw data table versus the final normalized tables. In addition a graphical user interface (GUI) was developed that allows a user to query the database in a flexible way. The performance measurements indicated that querying the normalized tables was more efficient than querying the raw data table.

Abstract:

This study involves a comprehensive examination of one book, Maya Angelou's autobiographical I Know Why Why the Caged Bird Sings, since it was first published in 1970. Recognized as an important literary work, the novel is used in many middle and secondary school classrooms throughout the united States. Additionally, the work often is challenged in public schools on the grounds of its sexual and/or racial content. The purpose of this study included establishing the importance of I Know Why the Caged Bird Sings as a significant literary work; documenting how and why the book is used in schools; recording the censorship history of the book and preparing a case study as an example of how censorship complaints can arise and how they can be handled. Additionally, this dissertation includes the interview responses of the book's author to various issues dealt with in this study. In this study, the researcher examined the reception of the book by reviewers at the time of publication and the literary criticism written about the book during the past twenty years. After examining the literary merits of the book, the researcher established the context in which the book came to be included in school classrooms. An historical account of the censorship challenges raised against the book is included. Finally, a case study is used as a point of reference to illustrate how a censorship challenge might come about when Maya Angelou's book is used in schools.

Full text

Abstract:

Abstract RF-gradients produced utilizing RF-field inhomogenity of conventional receiver/transmitter coil of NMR-probe can be used to mimic the effects of B0-gradients. This is done by placing long inhomogenous pulse in between two 90° pulses of appropriate phases (z-rotation cluster). B0-gradient based excitation sculpting can be converted into RF-gradient version. Selective one-dimensional TOCSY and NOESY using RF-gradient based excitation sculpting are described. In addition, non-selective two-dimensional experiments, TOCSY and NOESY, with RF-gradient based coherence selection are presented. Excitation sculpting using BIRD or BIRDR as inversion element results in isotope filter. Pre-suppression of non-13C-bound protons using RF-gradient BIRD prior to HSQC enables recording of spectrum of comparable quality to B0-gradient selected HSQC. This is beneficial for spectrometers lacking B0-gradient capabilities. Excitation sculpting using BIRDR can be used efficiently as low-pass filter in HMBC experiment. Furthermore, simultaneous elimination of protons bound to 15N and 13C can be accomplished with BIRDR based method.

Abstract:

In this thesis a dancing swan robot is made utilizing already existing components. Webuilt the neck from stacking servo-actuators on top of each-other. The legs are a beamconstruction with 1 degree of freedom. The wings have 4 degrees of freedom, of which 3 inthe shoulder joint. From the shoulder joint a beam protrudes outwards to an actuator in theelbow joint which in turn has a beam attached representing the outer wing. Communicationsare handled by USB transceivers making a regular personal computer capable of directlyinterfacing with the actuators. In order to choreograph the motion a recording solution wasimplemented utilizing the sensors in the servo-actuators to periodically sample the positionof the joints. A control program is developed to handle both playback of recorded motionand a prerecorded audio track. While recording the control program periodically polls theengines about their current position and stores the time and position in a table. Whenplaying the animation the control program periodically polls the table to see if any samplesare due, in which case it instructs the actuator to move towards the sample point.

Abstract:

Utifrån temat Hållbart Samhälle och aspekten Socialt Hållbart Samhälle, är denna uppsats en berättelse om ett examensarbete som tagit sig an leken i förhållande till funktionsnedsättningen autism hos barn och där frukten av examensarbetet blivit en leksaksprodukt. Med hjärta, hjärna och engagemang har jag undersökt utifrån mina användare hur jag kan skapa en artefakt med potential att ge mina användare förutsättningar som de behöver för att leka, samspela och kommunicera. Men även andra barns behov i lek, samspel och kommunikation har varit viktiga att tillgodose då målet har varit att möjliggöra det sociala samspelet mellan båda dessa parter. Med andra barn menas barn oavsett funktionsnedsättning eller ej. Målet har därmed även varit att formge en leksaksprodukt som möter dessa två parters behov, såväl till form som funktion. Visuellt ska leksaksprodukten inte ge något uttryck av hjälpmedel, utan ska snarare vara en leksak som dolt kan tillgodose behoven hos barn med autism. Examensarbetet har även varit en möjlighet för mig som designstudent att få lära mig om hur företag arbetar med design för barn, vilket har lett mig till företaget BRIO AB som givit sina erfarenheter samt åsikter till leksaksprodukten. Leksaksprodukten har även på så sätt haft utgångspunkten i vad jag som designer tror skulle kunna passa in i BRIOs sortiment av leksaker. Som designer har jag ambitionen att arbeta med lekfull och hållbar design för barn. Barn med autism var ett steg för mig att ge mitt område större komplexitet för att ge mig en möjlighet att utvecklas.

Abstract:

Individuals of a given population share more behavioural traits with each other than with members of other populations. For example, in humans, traditions are specific to regions or countries. These cultural relationships can tell us about the history of the populations, their origin and the amount of exchange between them. In birds, regional dialects have been described in many species. However, the mechanisms with which dialects form in populations is not fully understood because it is difficult to analyse experimentally. Translocated populations, with their known histories, offer an opportunity to study these mechanisms. From the study of bird vocalisations we can make inferences regarding population structure and relationships as well as their history, individual behavioural state, neuronal and physiological mechanisms or development of neuronal learning. Too achieve this, cross-disciplinary approaches are necessary, combining field work, bioacoustic methods, statistical tools such as machine learning, ecological knowledge and phylogenetic methods. Here, I will describe computational methods for the treatment and classification of bird vocalisations and will use them to depict the relationships between bird populations. First, I discretise the data in order to define the cultural traits. Then phylogenetic tree-building methods are used. Two approaches are possible, first to map these traits onto known phylogenies and, second, to directly build the phylogeny of these traits. I describe the application of these methods to test several hypothesis on bird songs evolution related to both their history and the mechanisms with which they evolve. Evidence for the presence of dialects in the Puget Sound white-crowned sparrow (Zonotrichia leucophrys pugetensis) is provided on the basis of the syllable content of the songs. The absence of vocal sexual dimorphism is reported in the Australasian gannet (or takapu, Morus serrator), a member of the Sulidae family for which extensive sexual dimorphism has been reported in other species. Subsequently, convergence between the begging calls of several cuckoo species and their respective hosts is suggested by various bioacoustic methods. In addition, the male calls of the hihi (or stitchbird, Notiomystis cincta) is analysed in an island population. The corresponding pattern of variation suggests a post-dispersal acquisition of calls via learning which is in agreement with the most related species in the revised phylogeny of the hihi. Finally, the mechanisms of song evolution are depicted in translocated populations of tieke (or saddleback, Philesturnus carunculatus rufusater), resulting in the development of island dialects.

Abstract:

Avian flight performance decreases with body size in birds, but previous work has been unable to define the underlying mechanism. Wingbeat frequency is hypothesized to ultimately constrain flight performance via muscular mechanical power output because frequency decreases with body size. I measured maximal burst take-off and vertical accelerating flight in 32 species of songbirds (Passeriformes), including the entire range of body mass in this clade (5-900 g). Jump forces against the ground were recorded with a forceplate. High-speed digital video captured the movement of morphological landmarks in order to estimate aerodynamic power requirements and dynamic morphology in flight. Surgically implanted gauges recorded the components of muscle power (muscle length change, force production, frequency) in the four largest species (Common raven, American crow, Black-billed magpie, and Gray jay). Flight performance and total aerodynamic power scaled with negative allometry, but were significantly influenced by foraging ecology. Species that forage on the ground had relatively lower jump impulses, shorter wings, higher wingbeat frequencies, and higher power output than species that forage on elevated substrates. I also found two unexpected internal scaling patterns. Both proportional muscle length change (muscle strain) and average cross-sectional area specific force (muscle stress) increased with size. Longer wingbeat cycles may permit more complete muscle activation in larger birds, thereby partially compensating for the constraint imposed by wingbeat frequency. These data offer the strongest support and the only direct evidence for power-limited scaling of flight performance to date.

Abstract:

This thesis investigates the ecological determinants of chewing louse (Insecta: Phthiraptera) host-specificity on four species of Malaysian swiftlets (Aves: Apodidae). Influences of host coloniality on louse ecology were also demonstrated, illustrating the dependence which these permanent ectoparasites have on their hosts. Louse collections were made to look for incidences of host-specific lice occurring on the "wrong" host ("straggling"). Straggling was observed, implying that lice disperse among host species. Thus, opportunity for louse dispersal (or lack thereof) does not govern the host-specificity of chewing lice on swiftlets. Experimental transfers of lice between hosts were conducted. Louse survival was reduced on foreign host species. This implies adaptation to specific host characters, suggesting that specialisation governs chewing louse host-specificity on swiftlets. There was no evidence for reciprocal adaptation of swiftlets to their normal louse species. Lice had no impact on the fitness of either swiftlets or the related common swift. Furthermore, neither swiftlet nor swift lice were transmitting pathogenic endoparasites. This implies that chewing lice and Malaysian swiftlets have not "coevolved". Survival of transferred lice was determined by the relatedness of donor and recipient hosts. Closer related swiftlet species are more similar in body size and feather dimensions. When the feather dimensions of the microhabitat distributions of the same louse species on different hosts were compared the results suggested that lice keep the dimensions of barb and barbule diameter, at which they occur, "constant" through microhabitat shifts. This suggests that feather dimensions are the host characters which determine the survival (and host-specificity) of chewing lice on birds. The ability of chewing lice to survive on hosts with similar feather morphology implies that "host-switching", between distantly related hosts with similar morphological characters (due to parallel or convergent host evolution), may have been an important factor in the evolution of bird-louse associations.

Abstract:

Replicate adaptive radiations occur when lineages repeatedly radiate and fill new but similar niches and converge phenotypically. While this is commonly seen in traditional island systems, it may also be present in host-parasite relationships, where hosts serve as islands. In a recent article in BMC Biology, Johnson and colleagues have produced the most extensive phylogeny of the avian lice (Ischnocera) to date, and find evidence for this pattern. This study opens the door to exploring adaptive radiations from a novel host-parasite perspective.See research article: http://www.biomedcentral.com/1741-7007/10/52 webcite

Abstract:

Airplanes have a risk of encounter birds while flying, taking off or landing and to ensure a safe flight the engines have to sustain functionality after one or several bird strikes; one vital part in the engine is the first stage rotor and hence it has to withstand bird strikes. Commercial finite element codes with explicit time marching techniques are commonly used today but they can be time-consuming and therefore a faster analytical method is sought. An analytical method is suitable for comparison of rotor blades in an early design process. The force during the bird strike was divided into two parts in accordance with a paper by Sinha et al. [1], a slicing force and a travelling force. Once the force was obtained it was transformed to a pressure over an area. The pressure and area was then used to perform a transient analysis in ANSYS. The analytical based results are then compared to results obtained in a simulation done in LS-DYNA. The force exerted on a rotor blade, analytical and in LS-DYNA, shows good agreement with respect to maximum force. Comparing the displacement of the rotor blade in ANSYS and LS-DYNA shows that the magnitude agrees well but the phase does not agree as well. It is possible to make automated scripts with a minimum of input data required to perform the analysis. The slicing force shows a good estimate of the maximum force exerted on a single blade during a bird strike. The impulse of the slicing force can also be seen as a lower limit of the total impulse felt by a single blade. The travelling force based on the paper by Sinha et al. was found to have some insufficiency and the recommendation is therefore to exclude the travelling force, in current state, from the analysis.

Abstract:

A fifty page manuscript of poetry and a critical introduction detailing the poet's aesthetics. Using the idea of the double-image and eroticism, the poet places her work in the category of the surreal. She describes the process of writing poetry born of fragmentary elements as a feminist emergence of agency. The manuscript is composed of four sections, each an element in the inevitable breakdown of a love relationship: meeting, love-making, birth of a child, death. Quotes from various authors of anthropological and fictional texts begin each section to reinforce thematic structure in a process of unveiling the agency of the narrator. The poems are organized as a series, beginning and ending with sequence poems.

Abstract:

Sweet Bird of Youth is Tennessee William's atmospheric play of 1959 about Chance Wayne, the one-time heart-throb of his hometown who returns hoping to break into the movies and find the girl he loved in his youth. Accompanied by faded movie star, Alexandra Del Lago, grieving in a haze of drugs and alcohol for her lost youth, he discovers that time is shortly to catch-up with him and wreak a terrible retribution for his past actions. In its exploration of corruption, ageing and the effects of time, the play offers a magnificent study of the dark side of the American dreams of youth and fame.This Student Edition provides an extensive introduction and notes by Katherine Weiss. The introduction includes a chronology of Williams' life and times, a summary of the plot, commentary on the characters, themes, language and context, and a production history of the play. Together with questions for further study and notes on words and phrases from the text, this is the essential edition of the play for students of literature and drama.

Abstract:

This study investigates how best to solve difficulties that may arise when translating bird literature from English into Swedish. The focus of the study lies on the translation of attributive adjectives and bird terminology. The text chosen for the translation, which serves as the basis for the analysis, is the section on general habits of the Turdidae-family in the comprehensive work Handbook of the Birds of the World. Translation theory that proved helpful in the translation process and in the subsequent analysis was primarily that of Vinay and Darbelnet (1995, 2004), Nida (1964a) and Newmark (1981). In most cases a literal translation could be perfonned, both in regard to attributive adjectives and bird tenninology, however, in some cases other translation procedures, such as transposition and equivalence, proved useful. Attributive adjectives that could not be translated literally, or that were preferred not to be translated literally, were translated through the use of transposition, into for instance: compound nouns, prepositional phrases, relative clauses and that-clauses. Bird terminology for which no suitable corresponding terminology could be found in the target language, was translated non-literally through the use of equivalence, into structures maintaining the equivalent semantic meaning in a natural way.
