Portrait of the artist as a feminist, practice-led researcher

Becoming a researcher, like any process of cultural initiation, is a complicated negotiation of processes and identity. While it is tempting to imagine that a researcher is just 'one who researches', the reality is far more complex and can be thought of as a journey rather than a sudden change of role. In practice-led research there is often a final and difficult assessment that needs to be made of that journey, and this requires the collation and integration of seemingly schizophrenic elements into one coherent body of findings. This paper attempts to outline the underlying “system of methods used in a particular area of study or activity” that have defined my research journey. It discusses the various elements that have informed and directed this enquiry, which include, but are not limited to: practice-led research, reflexivity, and post/academic writing, all underpinned by a feminist approach.

A Model of Anomalous Chain Translocation Dynamics

A model of polymer translocation based on the stochastic dynamics of the number of monomers on one side of a pore-containing surface is formulated in terms of a one-dimensional generalized Langevin equation, in which the random force is assumed to be characterized by long-ranged temporal correlations. The model is introduced to rationalize anomalies in measured and simulated values of the average time of passage through the pore, which in general cannot be satisfactorily accounted for by simple Brownian diffusion mechanisms. Calculations are presented of the mean first passage time for barrier crossing and of the mean square displacement of a monomeric segment, in the limits of strong and weak diffusive bias. The calculations produce estimates of the exponents in various scaling relations that are in satisfactory agreement with available data.

Effect of graded levels of rapeseed oil in isonitrogenous diets on the development of the gastrointestinal tract, and utilisation of protein, fat and energy in broiler chickens

The effect of feeding 0, 4, 8 and 16% rapeseed oil from 12-42 days of age was studied in broiler chickens on performance, digestibility of nutrients, and development of gastrointestinal tract, protein and energy metabolism. Thirty six female chickens (Ross 208) with initial body weight average 246 g were allocated to the four groups and kept pair-wise in metabolism cages. The chickens were fed similar amounts of metabolisable energy (ME) per day and similar amounts of essential amino acids relative to ME by adjusting with crystalline amino acids. The chickens were subjected to four balance periods each of five days with two 24 h measurements of gas exchange in two open-air-circuit respiration chambers inserted on the second and third day of each period. The addition of rapeseed oil increased the amount of gutfill indicating a reduced rate of passage and causing a hypertrophy of the gastrointestinal tract. There was a positive effect on feed utilisation as well as on digestibility especially of dietary fat together with higher utilisation of protein with addition of rapeseed oil. The partial fat digestibility of rapeseed oil estimated by regression was 91.1% and the partial metabolisability (ME/GE) of the rapeseed oil was estimated to 85% yielding an apparent metabolisable energy value of 34.30 MJ/kg.

The Barretstown experience

The thesis was prompted by a simple clinical observation. Seriously ill children returning from Barretstown Holiday Camp appeared changed. Barretstown ‘magic’ confuses the issue but indicates real and clinically evident transformations. The project sought to understand the experience and place it in a recognisable framework. The data was collected by interviews, observations as camp Paediatrician, memberships of the Child Advisory Committee and the Association’s criteria assessment team, participation in volunteer training and visits to international camps. The research presents evidence that the concepts of rite of passage, graceful mimesis and salutogenesis clarify operative social processes. The passage stages of separation, transition and reaggregation can be identified. Passage rites reorder personal and social upsets to fresh arrangements that facilitate change. Interviews confirm the reordering impact of achievements in play activities. These are challenging experiences closely guided by their Masters of Ceremonies – the Caras. The Cara/camper relationship is crucial and compatible with Girard’s theory of external mimesis. Visits to four camps confirm an inspirational process in contrast to a reported camp with a predetermined formative influence. Charismatic Caras/Councillors inspire playful mimesis and salutogenic transformations. Health is more than correction of pathogenic deficits and restoration of homeostasis. Salutogenic health promotes heterostasis – a desire for optimal experiences underpinned by a sense of coherence and adequate resources. Some evidence is presented that children have an improved sense of coherence after camp, which enables them to cope better with the demands of ill health. The camps enable sick children to up regulate risk taking towards more heterostatic experiences rather than down regulate their expectations. The heterostatic impulse can explain the disability paradox of good quality of life in the presence of severe disability. The salutogenic power of Barretstown can trump the pathogenic effects of childhood cancer and other serious illnesses.

Effect of relativistic plasma on extreme-ultraviolet harmonic emission from intense laser-matter interactions

Experiments were performed in which intense laser pulses (up to 9x10(19) W/cm(2)) were used to irradiate very thin (submicron) mass-limited aluminum foil targets. Such interactions generated high-order harmonic radiation (greater than the 25th order) which was detected at the rear of the target and which was significantly broadened, modulated, and depolarized because of passage through the dense relativistic plasma. The spectral modifications are shown to be due to the laser absorption into hot electrons and the subsequent sharply increasing relativistic electron component within the dense plasma.

African Nazarites : a comparative religious ethnography of Rastafari and Ibandla lamaNazaretha

Deux mouvements théologiques et culturels actuellement en croissance rapide suscitent un intérêt mondial, Ibandla lamaNazaretha et les Rastafari. Fondé par le Zulu prédicateur Isaiah Shembe pendant les années 1910, Ibandla lamaNazaretha prend son origine d’une église hiérarchique célébrant dans des temples extérieurs dans la province de KwaZulu-Natal et inclut maintenant un certain nombre de factions regroupées autour de la péninsule de l’Afrique du Sud. Le groupe des Rastafari, quant à lui, né en Jamaïque, a commencé comme une idéologie à plusieurs têtes qui a fleuri dans des zones éparses de l’île des Caraïbes. Il découle des interprétations d’une prophétie généralement attribuée à Marcus Garvey, concernant un roi devant être couronné en Afrique (circa 1920), et qui fut appliquée aux années 1930, avec le couronnement de Ras Tafari Makonnen comme Haile Selassie I, 225e empereur d’Éthiopie. Les adhérents et sympathisants de ces deux mouvements se comptent en dizaines de millions et ils exercent plusieurs types d’influences, tant aux niveaux politique, théologique, social que culturel, en particulier en Afrique et dans les Caraïbes aujourd’hui. Cette thèse soutient que les deux, Ibandla lamaNazaretha et les Rastafari, perpétuent un amalgame entre le « Naziréat » de l’Ancien Testament (Nombres 6:1-8) et le « Nazaréen » de l’évangile de Matthieu (2:23), à travers la dévotion à un seigneur contemporain: Haile Selassie I dans le cas du mouvement Rastafari et Isaiah Shembe dans le cas du mouvement Ibandla lamaNazaretha. Dans ce cadre théologique, à la fois les Rastafari et Ibandla lamaNazaretha ont réanimé les anciens rites de purification judaïques du naziréat jusque-là disparus, et les ont également adaptés, dans le contexte du messianisme, aux préoccupations postcoloniales de l’autochtonie. Grâce à la persistance de l’autochtonie, l’influence des idéaux indiens de résistance non-violente, et l’appropriation des différents thèmes bibliques, les deux mouvements africains noirs ont habilité avec succès leurs membres « dépossédés ». Ils l’ont fait par la création de communautés liminales, alors que des modes de vie agraires et auto-suffisants s’épanouissent en dehors des auspices d’une élite dominante : une herméneutique du nazaritisme unifie les diverses racines hybrides africaines, judaïques, chrétiennes, indiennes, et européennes.

Effects of Different Feeding Regimes on the Digestibility and Faecal Excretion of Nitrogen, Soluble Carbohydrates and Fibre Fractions in Water Buffaloes kept under Subtropical Conditions

In the course of the ‘Livestock Revolution’, extension and intensification of, among others, ruminant livestock production systems are current phenomena, with all their positive and negative side effects. Manure, one of the inevitable secondary products of livestock rearing, is a valuable source of plant nutrients and its skillful recycling to the soil-plant interface is essential for soil fertility, nutrient - and especially phosphorus - uses efficiency and the preservation or re-establishment of environmentally sustainable farming systems, for which organic farming systems are exemplarily. Against this background, the PhD research project presented here, which was embedded in the DFG-funded Research Training Group 1397 ‘Regulation of soil organic matter and nutrient turnover in organic agriculture ’ investigated possibilities to manipulate the diets of water buffalo (Bubalus bubalis L.) so as to produce manure of desired quality for organic vegetable production, without affecting the productivity of the animals used. Consisting of two major parts, the first study (chapter 2) tested the effects of diets differing in their ratios of carbon (C) to nitrogen (N) and of structural to non-structural carbohydrates on the quality of buffalo manure under subtropical conditions in Sohar, Sultanate of Oman. To this end, two trials were conducted with twelve water buffalo heifers each, using a full Latin Square design. One control and four tests diets were examined during three subsequent 7 day experimental periods preceded each by 21 days adaptation. Diets consisted of varying proportions of Rhodes grass hay, soybean meal, wheat bran, maize, dates, and a commercial concentrate to achieve a (1) high C/N and high NDF (neutral detergent fibre)/SC (soluble carbohydrate) ratio (HH), (2) low C/N and low NDF/SC ratio (LL); (3) high C/N and low NDF/SC ratio (HL) and (4) low C/N and high NDF/SC (LH) ratio. Effects of these diets, which were offered at 1.45 times maintenance requirements of metabolizable energy, and of individual diet characteristics, respectively, on the amount and quality of faeces excreted were determined and statistically analysed. The faeces produced from diets HH and LL were further tested in a companion PhD study (Mr. K. Siegfried) concerning their nutrient release in field experiments with radish and cabbage. The second study (chapter 3) focused on the effects of the above-described experimental diets on the rate of passage of feed particles through the gastrointestinal tract of four randomly chosen animals per treatment. To this end, an oral pulse dose of 683 mg fibre particles per kg live weight marked with Ytterbium (Yb; 14.5 mg Yb g-1 organic matter) was dosed at the start of the 7 day experimental period which followed 21 days of adaptation. During the first two days a sample for Yb determination was kept from each faecal excretion, during days 3 – 7 faecal samples were kept from the first morning and the first evening defecation only. Particle passage was modelled using a one-compartment age-dependent Gamma-2 model. In both studies individual feed intake and faecal excretion were quantified throughout the experimental periods and representative samples of feeds and faeces were subjected to proximate analysis following standard protocols. In the first study the organic matter (OM) intake and excretion of LL and LH buffaloes were significantly lower than of HH and HL animals, respectively. Digestibility of N was highest in LH (88%) and lowest in HH (74%). While NDF digestibility was also highest in LH (85%) it was lowest in LL (78%). Faecal N concentration was positively correlated (P≤0.001) with N intake, and was significantly higher in faeces excreted by LL than by HH animals. Concentrations of fibre and starch in faecal OM were positively affected by the respective dietary concentrations, with NDF being highest in HH (77%) and lowest in LL (63%). The faecal C/N ratio was positively related (P≤0.001) to NDF intake; C/N ratios were 12 and 7 for HH and LL (P≤0.001), while values for HL and LH were 11.5 and 10.6 (P>0.05). The results from the second study showed that dietary N concentration was positively affecting faecal N concentration (P≤0.001), while there was a negative correlation with the faecal concentration of NDF (P≤0.05) and the faecal ratios of NDF/N and C/N (P≤0.001). Particle passage through the mixing compartment was lower (P≤0.05) for HL (0.033 h-1) than for LL (0.043 h-1) animals, while values of 0.034 h-1 and 0.038 h-1 were obtained for groups LH and HH. At 55.4 h, total tract mean retention time was significantly (P≤0.05) lower in group LL that in all other groups where these values varied between 71 h (HH) and 79 h (HL); this was probably due to the high dietary N concentration of diet LL which was negatively correlated with time of first marker appearance in faeces (r= 0.84, P≤0.001), while the dietary C concentration was negatively correlated with particle passage through the mixing compartment (r= 0.57, P≤0.05). The results suggest that manure quality of river buffalo heifers can be considerably influenced by diet composition. Despite the reportedly high fibre digestion capacity of buffalo, digestive processes did not suppress the expression of diet characteristics in the faeces. This is important when aiming at producing a specific manure quality for fertilization purposes in (organic) crop cultivation. Although there was a strong correlation between the ingestion and the faecal excretion of nitrogen, the correlation between diet and faecal C/N ratio was weak. To impact on manure mineralization, the dietary NDF and N concentrations seem to be the key control points, but modulating effects are achieved by the inclusion of starch into the diet. Within the boundaries defined by the animals’ metabolic and (re)productive requirements for energy and nutrients, diet formulation may thus take into account the abiotically and biotically determined manure turnover processes in the soil and the nutrient requirements of the crops to which the manure is applied, so as to increase nutrient use efficiency along the continuum of the feed, the animal, the soil and the crop in (organic) farming systems.

Predicting the profile of nutrients available for absorption: from nutrient requirement to animal response and environmental impact

Current feed evaluation systems for dairy cattle aim to match nutrient requirements with nutrient intake at pre-defined production levels. These systems were not developed to address, and are not suitable to predict, the responses to dietary changes in terms of production level and product composition, excretion of nutrients to the environment, and nutrition related disorders. The change from a requirement to a response system to meet the needs of various stakeholders requires prediction of the profile of absorbed nutrients and its subsequent utilisation for various purposes. This contribution examines the challenges to predicting the profile of nutrients available for absorption in dairy cattle and provides guidelines for further improved prediction with regard to animal production responses and environmental pollution. The profile of nutrients available for absorption comprises volatile fatty acids, long-chain fatty acids, amino acids and glucose. Thus the importance of processes in the reticulo-rumen is obvious. Much research into rumen fermentation is aimed at determination of substrate degradation rates. Quantitative knowledge on rates of passage of nutrients out of the rumen is rather limited compared with that on degradation rates, and thus should be an important theme in future research. Current systems largely ignore microbial metabolic variation, and extant mechanistic models of rumen fermentation give only limited attention to explicit representation of microbial metabolic activity. Recent molecular techniques indicate that knowledge on the presence and activity of various microbial species is far from complete. Such techniques may give a wealth of information, but to include such findings in systems predicting the nutrient profile requires close collaboration between molecular scientists and mathematical modellers on interpreting and evaluating quantitative data. Protozoal metabolism is of particular interest here given the paucity of quantitative data. Empirical models lack the biological basis necessary to evaluate mitigation strategies to reduce excretion of waste, including nitrogen, phosphorus and methane. Such models may have little predictive value when comparing various feeding strategies. Examples include the Intergovernmental Panel on Climate Change (IPCC) Tier II models to quantify methane emissions and current protein evaluation systems to evaluate low protein diets to reduce nitrogen losses to the environment. Nutrient based mechanistic models can address such issues. Since environmental issues generally attract more funding from governmental offices, further development of nutrient based models may well take place within an environmental framework.

Contextual, but not auditory, fear conditioning is disrupted by neurotoxic selective lesion of the basal nucleus of amygdala in rats

The basolateral amygdala complex (BLA) is involved in acquisition of contextual and auditory fear conditioning. However, the BLA is not a single structure but comprises a group of nuclei, including the lateral (LA), basal (BA) and accessory basal (AB) nuclei. While it is consensual that the LA is critical for auditory fear conditioning, there is controversy on the participation of the BA in fear conditioning. Hodological and neurophysiological findings suggest that each of these nuclei processes distinct information in parallel; the BA would deal with polymodal or contextual representations, and the LA would process unimodal or elemental representations. Thus, it seems plausible to hypothesize that the BA is required for contextual, but not auditory, fear conditioning. This hypothesis was evaluated in Wistar rats submitted to multiple-site ibotenate-induced damage restricted to the BA and then exposed to a concurrent contextual and auditory fear conditioning training followed by separated contextual and auditory conditioning testing. Differing from electrolytic lesion and lidocaine inactivation, this surgical approach does not disturb fibers of passage originating in other brain areas, restricting damage to the aimed nucleus. Relative to the sham-operated controls, rats with selective damage to the BA exhibited disruption of performance in the contextual, but not the auditory, component of the task. Thus, while the BA seems required for contextual fear conditioning, it is not critical for both an auditory-US association, nor for the expression of the freezing response. (C) 2009 Elsevier Inc.

Aspects of Liminality in Eilis Ni Dhuibhne's The Dancers Dancing

In this essay I refer Eilis Ni Dhuibhne’s narrative construction of the main characters and the theme of the novel The Dancers Dancing, in the context of the anthropologist Victor Turner’s concept of liminality. Thus the summer in the Gaeltacht that five teenage girls experience, can be understood as a depiction of the liminal phase in a rite of passage. Ni Dhuibhne’s differently constructed characters enlighten different aspects of liminality and through the céilí dance their experiences are exposed. Furthermore this essay suggests that Julia Kristeva’s notion of the chora, which can be associated to dance, is also relevant when describing the unbounded and unlimited process that radically can reform social structures. I conclude that the liminal space offers an area of many possibilities. It functions as a free zone where the main characters can freely explore their personal issues that trouble them, or the difficulties of their own society.
