This study’s purpose was to explore science engagement and in/equity through science educators’ narratives of servant leadership at both the K-12 and higher education levels in the United States. The research question was: How have participants become and led others to become engaged in science? I took an arts-based approach using drawings and autobiographical data to initiate and create metissages focused on becoming engaged in science education. The findings were that: (1) Participants helped marginalized students understand the culture of science through pedagogical strategies that connected self and science; (2) Participants recognized and countered systemic forms of oppression for students who are marginalized in science education through outreach in STEM; and (3) Participants offset disengagement in science among underserved groups through meaningful relationships and presented non-dominant examples of scientific inquiry. I discuss their implications for professional development and provide recommendations for future research concerning leadership/followership aimed at promoting science equity.

The welfare of young pigs was compared in different housing systems using a range of indicators. Groups of twenty pigs were weaned at 6.4 kg into each of four pens built within environmentally-controlled rooms: a) deep-straw; b) Straw-Flow(R) (1 kg straw daily); c) large expanded metal-floored flatdeck; d) small flatdeck. Kennelled lying areas were provided in a and b. Stocking densities were 0.229 m2/pig for a,b and c, and 0.173 m2/pig for d. After 4-5 weeks (19.6 kg liveweight), sixteen pigs from each pen were moved into Straw-Flow grower pens (0.675 m2/pig) and observed until slaughter at 90.6 kg. The remaining pigs were grouped together to examine the effects of mixing. Housing type did not affect growth and feed intake. Food conversion ratio was poorer in large flatdeck than in small flatdeck or Straw-Flow. Behavioural differences between Straw-Flow and deep-straw related to differences in available straw; there were few differences between flatdecks. Access to straw affected pig-directed, pen-directed and straw-directed behaviours. Foot injuries recovered rapidly on deep-straw and increased in flatdecks immediately after weaning (Straw-Flow intermediate); injuries were more persistent in small flatdeck. Deep-straw prevented adventitious bursitis of the hock. Antibody response was examined by challenge with keyhole limpet haemocyanin (KLH). Immunoglobulin (Ig) M response was greater in straw pens. Dust concentration was higher in kennelled lying areas than flatdecks. With removal of kennels, straw pens showed less dust than flatdecks. Thus, welfare of early-weaned pigs in deep-straw was very good, flatdecks poor with Straw-Flow closer to deep-straw than to flatdecks. Early experience had limited effects. Pigs from flatdecks performed increased rooting relative to deep-straw two weeks after moving (Straw-Flow intermediate). These differences did not persist. Pigs mixed at 20 kg showed increased aggression (not significant) and decreased Ig m response to KLH, indicating reduced welfare.

Chainmail is a type of body armor that has been used throughout ancient and modern times by a variety of people, including medieval fighters and ocean divers. Articles of chainmail are made out of interconnected metal rings - usually steel rings - that are either butted, welded, or riveted together. The primary failure mechanism of a piece is usually the rings being pried apart by a wedge-shaped object, such as the tip of a sword or a shark tooth. The ability of an article of chainmail to resist such failures depends on a variety of variables including the method of closure of the rings, the diameter and gauge of the rings used, and the weave type. The relative strengths of different types of chainmail were investigated by conducting tensile tests on both physical and simulated samples. Eight different ring diameters, four different ring gauges, four different weaves, and three methods of closure of the rings (butting, riveting, and welding) were tested. For both methods of analysis, force-displacement curves were generated for each sample, and the yield forces, maximum forces, and effective elastic moduli extracted from the graphs. Proportional relationships between the physical characteristics of the chainmail and the forces and moduli were obtained graphically through analysis of the experimental data. The yield and maximum forces were determined to vary directly with the number of rings linked to a given ring, with an average error of 10.66 5.67 %. These parameters were also found to vary inversely with the ring diameters, with an average percent error of 14.63 5.61 %. The samples with welded rings were found to yield at a force at least 1.5 times higher than the yield force of the riveted samples and at a force at least 2 times higher than the yield force of the butted samples. The effective elastic moduli decreased with increasing diameter and held relatively constant across the different methods of ring closure. The attempt to scale the forces and moduli with the cross-sectional area of the rings proved inconclusive due to large percent differences between the scaled values. The experimental results were compared to those generated by nonlinear, dynamic SolidWorks simulations. The verification of the simulated results with the experimental results allowed investigation into possible sources of error in the experimentation via simulation. Variations in the orientation of the rings resulted in variations in the yield force up to 33.31%. The yield force was also found to decline as a rate of 100 N for each millimeter of width of the split in the butted rings. Thus, the simulations provided possible explanations for some of the larger percent differences found during the creation of the proportional relationships - including the inconclusive results for scaling with cross-sectional area. Despite the possibilities for error, there exists strong support for the scaling relationships established for weave type and ring diameter due to the low percent errors calculated, as well as the low percent errors between the simulated and experimental values.

Ferguson, Jim. "A weaver in wartime : a biographical study and the letters of Paisley weaver-poet Robert Tannahill (1774-1810)." Thesis, University of Glasgow, 2011. http://theses.gla.ac.uk/2395/.

Повний текст джерела
Анотація:
This thesis is a critical biography of Robert Tannahill (1774-1810). As a work of recovery its aim is to lay out the details of the life and in so doing to make the case for Tannahill as a distinctive figure in Scottish literary history. Part One covers the main events in Tannahill’s life, and analyses his poetry, songs and play, The Soldier’s Return, drawing heavily on his extant correspondence throughout. Part Two of the thesis gives all of Tannahill’s extant correspondence. The received critical opinion of Tannahill in the nineteenth century was that his true talent lay in the writing of Scottish pastoral songs. In accordance with this perception the other aspects of his work have, generally, been treated as marginal by previous critics. This thesis aims to broaden the critical understanding of Tannahill as a writer working in the first decade of the 1800s by taking into consideration his social and political milieu, the writers he was influenced by and his response to particular events in his life and in the world. I argue that Tannahill was not party political, but had sympathy for Whig causes such as abolition of the death penalty and of slavery. He also opposed cock-fighting and animal cruelty. Key to understanding much of Tannahill’s output was his attitude to the wars with Revolutionary and Napoleonic France (1793-1815). Fear of French invasion of the British Isles was something that exercised Tannahill a good deal. His attitude to war was that it was pointless human folly, but his dislike of all imperialism, including British and French, makes his position complex and the complexity of his response to war is a recurring theme throughout. Tannahill’s upbringing in Paisley and his position as an artisan weaver had a profound effect on his writing, as did the influence of Robert Burns. Tannahill was fiercely independent, despised literary patronage and inherited wealth and power. There is an attempt to explain and understand how and why Tannahill came to hold these points of view and to point out where they find expression in his work. Chapter 1 looks at Tannahill’s upbringing and life in Paisley. Chapter 2 deals with the ‘Critical Reception’ of his work from 1815 to the present. Chapter 3 looks in depth at his attitudes to war and the threat of French invasion. Chapter 4 concentrates on Tannahill’s play The Soldier’s Return and considers how it fits into the pastoral tradition. Chapter 5 looks at the content and some formal aspects of his poetry and Chapter 6 deals with the range of his lyrics and songs. Part Two is a project of retrieval, sub-titled The Letters of Robert Tannahill, it presents in chronological order eighty-two letters, the vast majority of which were written by Tannahill to friends and acquaintances between the years 1802 and 1810. It has been compiled from holograph manuscript sources found in the University of Glasgow Library, the National Library of Scotland, University of Edinburgh Library and Paisley Central Library. In addition, letters previously published in the David Semple edition of Tannhill’s Poems, Songs and Correspondence (1876) have been inserted to give the most comprehensive collection of Tannahill correspondence to date. These letters give a fascinating insight into Tannahill’s life and work. The guiding editorial principle for transcription from holograph has been: to provide as accurately as possible a text free from editorial interference.

I am interested in experiences and knowledge that is passed on from generation to generation, and in a broad sense this is the starting point of my thesis project.  I am of Kurdish descent, and I knew early on that I wanted to make a project that related to Kurdish tradition. I was specially intrigued by Kurdish weaving craft and how this particular tradition could be architecturally interpreted and used as a tectonic component. I wasn´t interested in simply reproducing traditional architecture, but rather using certain techniques and methods as a way of conceiving something new. Within my family, there is experience in weaving. With their knowledge, it has helped me technically but also with issues relating to the social and traditional. The study is based on developing design techniques of Kurdish weaving techniques and principles. My design technique has mostly been focused on the slit tapestry technique, more commonly known as kelim, where openings are created when two separately woven areas of weft meet along adjacent warps and do not interlock. Using this technique, there is room for spontaneity, which has allowed me to use the weave frame and warp to develop my design technique. In addition to weaving tradition, the project is also based on Kurdish vernacular architecture as well as Islamic architecture in terms of climatic and social aspects.
Jag är intresserad av erfarenheter och kunskap som förs vidare från generation till generation, och i en bred mening är detta utgångspunkten för mitt examensarbete. Jag är av kurdisk härkomst, och jag visste tidigt att jag ville göra ett projekt som relaterade till kurdisk tradition. Jag var speciellt fascinerad av kurdisk vävning och hantverk, och hur denna tradition kunde omtolkas arkitektoniskt och användas som en tektonisk komponent. Jag var inte intresserad av att helt enkelt reproducera traditionell arkitektur, utan snarare att använda vissa tekniker och metoder som ett sätt att skapa något nytt. Inom min familj, finns det erfarenhet av vävning. Med sin kunskap, har det hjälpt mig tekniskt men även med frågor som rör den sociala och traditionella. Studien bygger på att utveckla designtekniker and kurdisk vävtekniker och principer. Min designteknik har främst varit inriktad på slit tapestry tekniken, mer känd som kelim, där öppningar skapas när två separat vävda områden väft möts längs intilliggande varptrådar utan att låsas. Med denna teknik, finns det utrymme för spontanitet, vilket har tillåtit mig att använda väv ramen och varpen att utveckla min designteknik. Förutom vävning tradition, är projektet också baserat på den lokala successiva arkitekturen samt islamisk arkitektur när det gäller klimat-och sociala aspekter.

Includes bibliographical references (unnumbered pages 41-42).
The thesis is based on physical interactivity between a user's physical body and the built environment. The relationship between body and architecture is challenged by the demands and desires for adaptability and interactivity, however material and construction methods of architecture have changed little to address these concerns. By allowing the user to become an instigator and an active controller for organizing space and program. Architectural elements are enabled with flexibility and mutability, in terms of its skin and program, which are activated by the user. The first investigation explores three joints within the body and documents, analyses and transforms these joints into an architectural abstraction. Then the concept of collapsed and interactive skin is applied to a design proposal for the fagade for the Art Interactive Gallery. The fagade engages pedestrians visually as well as physically. The final component of the thesis redefines the program of a fitting room as a physically transformable and socially interactive fagade condition activated by the body's own movements. Throughout the research, the thesis has focused on the process of manipulating materials to create composite skin and structural conditions to further investigate the relationship between the body and architecture.

The current study examined if there was a statistically significant difference between Black females' hair preferences with regard to their levels of self-esteem. The researcher also examined if there was a statistically significant correlation between Black females' hair satisfaction and their self-esteem. Participants were given a 26-item online questionnaire that consisted of items from the Rosenberg Self-Esteem and Bankhead and Johnson Hair-Esteem Scale. A multiple comparison analysis revealed that there were no statistically significant differences between the self-esteem levels of Black females' based on their preferred hair preferences (f ( 4, 95) = 1.126, p=.349). However, a correlation analysis did indicate that higher levels of self-esteem were associated with higher levels of hair satisfaction - how satisfied one is with her hair (r =.540, n=99, p=.000).

The relationship between architecture and the individual involves a process of discovery through revelation, opportunity for choice, engagement of the senses, and the use of symbolism. As the experience of architecture meets the needs of humanity on a personal level, it has the capacity to draw the individual toward ultimate self-actualization through the process of discovery, with the potential to impact and transform a community.

The Tide Weavers Project examines the representation of landscape in motion picture films and explores the ways in which certain filmmakers closely reference the desert landscape to mirror and represent notions of self and consequently, to shape film character portrayal. I argue that these filmmakers use this setting to describe a particular relationship for themselves and their characters. In this relationship the desert becomes a space in which to project and examine aspects of self and it can initiate a transaction or relationship so intimate that at many points, (human) being becomes landscape, and landscape becomes being. I will draw on the work of a range of Philosophers and Postcolonial theorists to inform my reading of this relationship and to frame my engagement with specific Australian and international films. The inclusion and analysis of my own desert-based motion picture script Tide Weavers will add to my understanding of the possibilities of film (as a medium) provides for altering an audiences' reading of landscape. I challenge the notion of estrangement from the land, either though ignorance or where colonialist landscape theory detracts from a sense of connectedness, such as through the superficial or subjective application of cartography, fear arising from monotonous and unfamiliar geography, and the eroticising of land as woman. I engage with current theory surrounding the idea of fusion with landscape to open new opportunities for exploring landscape/character interaction. I also propose that collaborative working processes between indigenous and non-indigenous filmmakers have the potential to alter the ways in which landscape is both represented and interpreted. I then look at how these ideas are translatable to the themes of the Tide Weavers script. Grief and gender are primary themes, with an emphasis on how respite, sacred space and surrender to landscape can lead to healing. I believe this work will contribute to exciting new filmic interpretations of landscape theory.

This work positions itself in the intersection between art, fashion and crafts. The work aims to challenge traditional ways of making clothes by investigating the relationship between material, form and body through a three dimensional hand weaving technique with focus on up-cycling. The design examples were conducted through a series of experiments where different objects were investigated as alternative weaving looms. The study resulted in five design examples that argue the importance to maintain and develop craft techniques and to give suggestions of how to address the environmental problems within the industry.

This work places itself in the field of woven textile design and the lenticular effect in a spatial context. The lenticular effect refers to a ribbed surface structure which changes appearance depending on from which angle it is viewed. The aim is to combine woven pleats with colours and patterns to create a lenticular effect. Bindings, patterns and colours have been investigated in both handweaving and jacquard weaving. Three suggestions for a woven, pleated, shifting textile have been developed. The three tracks are a colour shift and gradient with a surface structure, a pattern shift taking place across all sides of a pleat and a jacquard pattern hidden between the pleats. By creating a textile which shifts as it is viewed from different angles and distances, the motive is to encourage movement around the woven piece, broaden the possible uses of woven textiles and invite the viewer to take a closer look at the woven structure.

In this thesis, we cover four research topics in the realm of the mechanics of slender structures involving strong geometric constraints: elastic gridshells, triaxial weaves, elastic clasps, and elastic knots. These studies involve a combination of geometric reasoning, high-fidelity numerical simulations, and precision model experiments using scale-invariance and advanced imaging techniques (e.g., 3D laser scanning, and X-ray computed tomography). First, we study the shape and the mechanical response of elastic gridshells, the three-dimensional structure of which results from the out-of-plane buckling of an initially flat and biaxial network of rods. A purely geometric continuum model, originally introduced by Chebyshev for woven fabric, is used to describe the underlying kinematics and form-finding. The results suggest that rod inextensibility, rather than elasticity, is the primary factor that determines the shape of elastic gridshells.
Second, we investigate triaxial weaving, a craft technique used to generate surfaces using tri-directional arrays of initially straight elastic ribbons. Traditional weavers intentionally introduce discrete topological defects, leading to unsmooth surfaces in the overall structure. As an alternative point of departure, we achieve smooth, threedimensional weaved structures by prescribing in-plane curvatures to the flat ribbons. We demonstrate that a continuous range of integrated Gaussian curvatures can be achieved, which is not feasible using straight ribbons. The potential of this novel design scheme is demonstrated with a few canonical target shapes.
Third, we investigate the mechanics of two elastic rods in a crossing contact, whose geometric counterpart is often referred to in the mathematics community as a 'clasp.' We compare our experimental and computational results to a well-established description for ideal clasps of geometrically rigid strings, finding that the latter acts as an underlying 'backbone' for the full elasticity solution. Our findings suggest that the tight contact between rods must be analyzed as a three-dimensional solid, not a one-dimensional rod. We also study a frictional elastic clasp with relative motion between the two rods. Finally, we present preliminary results on the full three-dimensional finite element method simulations of tight elastic knots, as a continuing discussion of tight contact between filaments. Our numerical results reveal significant deviations for the tight knots from existing one-dimensional models for loose overhand knots.
Our findings corroborate the three-dimensional nature of the tight contact that we demonstrated during the investigation of the elastic clasp.

When compared to northern temperate counterparts, birds in the tropics and Southern Hemisphere regions, are characterised by low fecundity, long developmental periods and high Survival. This pattern has been attributed to hypotheses relating to food limitation, nest predation, and reduced seasonality leading to high adult survival. Still, to date few studies have investigated this issue. In particular, detailed studies from southern regions are scarce and as a result our understanding of this question remains weak. Another characteristic of 'southern' birds is a higher frequency of cooperatively-breeding species. It has previously been shown that cooperative breeding is most frequent amongst species with high survival and low fecundity. An explanation for this could be that long occupancy of territories by long-lived breeders leads to reduced opportunities of independent breeding by young birds. However, the biology of some species is such, that they do not experience shortage of breeding territories or other constraints, while still showing delayed dispersal and cooperative breeding. This study investigates what factors drive life-history evolution in a cooperatively breeding southern African passerine, the sociable weaver Philetairus socius. This species departs from the traditional cooperative breeding model in being a non-territorial colonial nester that inhabits an unpredictable semi-arid environment. Sociable weavers face no obvious constraints on independent reproduction, yet cooperative breeding is common. Therefore, I also aimed at determining what factors prompt delayed reproduction in this species, since this life history trait is the first step leading to cooperative breeding.

For Virginia, the primary forage base is endophyte-infected tall fescue (Schedonorus phoenix (Scop.) Holub). However, the decreased animal performance and disorders caused by the presence of the fungal endophyte Neotyphodium coenophialum reduces its suitability for many forage-livestock producers. The endophyte, which is found in the inter-cellular space of tall fescue tissues, forms a mutalistic relationship with the plant and helps the fescue tolerate drought, insect predation, and grazing pressure. The production of toxic ergot alkaloids by the endophyte is associated with decreased performance of animals that graze endophyte infected tall fescue. The objective of the current experiment was to determine how tall fescue type (endophyte free vs novel endophyte) and orchardgrass-legume (alfalfa vs clover) mixture affect grazing behavior of weaned steers. Forty-eight weaned steers (218 ± 18 kg) were blocked by frame score (medium and large), and randomly assigned within block to four treatments with three replications in a 2x2 factorial design. Each treatment consisted of 2 paddocks with the combination of tall fescue and legume-orchardgrass mixture as follow: alfalfa-orchardgrass mixture (A)/E-, clover-orchardgrass mixture (C)/E- , A/E++ and C/E++. Each group of 4 steers had 24 h access to both tall fescue stand and legume-orchardgrass mixture. Botanical composition of paddocks was determined on d 0, and forage mass, sward height and nutritive value were determined on d 0, 17 and 33. Behavior of steers was scanned every 5 min on d 24 and 25 from 0700 to 1900. The proportion of legumes was higher (P = 0.001) in A paddocks(37 %) compared to C paddocks (6%), while the percent orchardgrass was lower (P = 0.040) in A (33 %) than C (53 %). The proportion of broadleaf and grassy weeds was higher (P = 0.013) in E- paddocks (11 %) as compared with E++ paddocks (3 %). Sward height and herbage mass were similar between treatments during the experiment (P > 0.05). Nutritive value (CP, NDF and ADF) did not differ between fescue paddocks (P > 0.05). However, within mixed swards, CP was higher and NDF was lower in A compared with C (P < 0.05). Acid detergent fiber was (P < 0.05) lower in A than C only on d 0 and 17. Average daily gain did not differ between treatments (P > 0.05). Steers spent higher (P = 0.002) proportion of the daylight time grazing in treatments with C (56 %) as compared with A (50 %), and in treatments (P = 0.023) with E++ (55 %) compared with E- (52 %). Time spent ruminating, idling and lying, as well as steps taken per day, did not differ between treatments (P > 0.05). Regardless of differences in weeds between E- and E++, these results indicate that fescue type affected grazing behavior of calves. Difference between mixed swards in proportion of ground cover with legumes and orchardgrass, as differences in nutritive value between A and C may have affected grazing behavior of calves between mixed swards, instead of a legume species effect within mixtures.

Manufacturing of thermoplastic composite based on textile preforms made from hybrid yarns is well suited for the production of fiber-reinforced plastic (FRP) in medium- and large-scale production runs. Especially, the consolidation of thermoplastic FRP is currently complicated by the high viscosity of molten material. Woven multilayered and z-reinforced NCF-preforms are very interesting for FRP supposed to withstand threedimensional loading and impact stress. These preforms with z-directional reinforcement improve the FRP delamination behavior and out-of-plane characteristics. The wellknown composite parameters are essential to ensure the use of these materials in a wide range of applications.

Dissertação de Mestrado Integrado em Medicina Veterinária
A criptosporidiose é uma das mais importantes causas de diarreia neonatal bovina, sendo uma potencial ameaça à produção e uma importante causa de prejuízos económicos. Vitelos recém-nascidos e até ao desmame são especialmente susceptíveis à infecção e desenvolvimento de sinais clínicos pelo parasita protozoário Cryptosporidium parvum, já que nascem quase completamente desprovidos de mecanismos de imunidade naturais. Este parasita é considerado existente mundialmente, ubiquitário, sem especificidade ao hospedeiro e oportunista. Os efeitos da infecção, nomeadamente a diarreia, desidratação e desequilibrios electrolíticos, juntamente com acidose metabólica, enfraquecem os animais e podem originar elevados níveis de morbilidade e mortalidade moderada, especialmente quando associado a outros agentes. Actualmente não é conhecido nenhum tratamento específico completamente eficaz no combate à criptosporidiose bovina. O tratamento baseia-se na terapia de suporte por meio de fluidoterapia oral e endovenosa. Medidas preventivas assentes em melhorias de higiene e administração correcta de colostro são consideradas as mais importantes. O potencial zoonótico do parasita, especialmente em indivíduos imuno-deprimidos, levanta preocupações de saúde pública. No presente trabalho, foram elaborados 2 estudos clínicos, tentando confirmar a existência, prevalência e sinais clínicos de criptosporidiose em regiões na Alemanha e em Portugal. Na Universidade Justus-Liebig em Giessen, Alemanha, 35 vitelos foram examinados tendo em conta os seus sinais clínicos. Vinte e dois dos animais examinados demonstraram sinais de diarreia e, entre estes, 36% excretavam oocistos. Seguiu-se um exame mais detalhado dos animais infectados, incluindo o estudo dos sinais clínicos e dos valores laboratoriais. Os sinais clínicos e laboratoriais detectados confirmaram os esperados (característicos da criptosporidiose), incluindo diarreia fluida, desidratação, fraqueza e hipotermia; acidose metabólica, aumento dos níveis de lactato e hiponatremia. Todos os vitelos recuperaram após fluidoterapia, controlo da acidose e antibioterapia. Lactato de halofuginona foi administrado em alguns animais mas não demonstrou efeitos evidentes. Em Portugal, 30 vitelos foram examinados numa exploração de engorda na área do Ribatejo, considerando os seus sinais clínicos e a presença de oocistos após análise pela técnica de Ziehl-Neelsen modificada. A prevalência foi elevada (43%). Os sinais clínicos variaram e a excreção de oocistos nem sempre estava acompanhada de diarreia (portadores assintomáticos). A evolução de quinze vitelos re-examinados variou, evidenciando por um lado a existência do carácter autolimitante (3 vitelos melhoraram) e por outro um possível aumento da mortalidade (2 vitelos morreram) associados à doença.
ABSTRACT - Cryptosporidiosis in pre-weaned calves – Observations in Germany and Portugal - Cryptosporidiosis is one of the most important causes of bovine neonatal diarrhea, being considered an important threat to bovine production and a cause of economical losses. Pre-weaned, neonatal calves are particularly prone to the infection and development of clinical signs due to the protozoan parasite Cryptosporidium parvum, as they are born almost completely deprived of natural immunity. This parasite is a worldwide existing, ubiquitous, non host specific and opportunistic agent of diarrhea. Dehydration and electrolyte imbalances, coupled with metabolic acidosis, weaken the animals and may cause high morbidity rates and moderate mortality, especially when occurring in combination with other infectious agents. No completely effective specific treatment for calf cryptosporidiosis is known to this date. Treatment is mainly based on supportive care by oral and intravenous fluid therapy. Prevention by hygiene measures, correct colostral administration and management seem to be most important. Public health concerns arise due to its zoonotic potential, especially in immune compromised individuals. In the present dissertation, two case studies were developed, trying to confirm the existence, prevalence and clinical signs of cryptosporidiosis in Germany and Portugal. In the Clinics for Obstetrics, Gynecology and Andrology with veterinary ambulance from the Justus Liebig University Giessen, Germany, 35 calves were examined for their clinical signs. 22 of the examined calves showed diarrhea and of these, 36% were positively excreting oocysts. A more detailed examination of the infected calves was performed and clinical signs and laboratory values studied. Detected clinical and laboratory signs could be confirmed by the expected (characteristic signs of cryptosporidiosis), including watery to thin mushy diarrhea, dehydration, weakness and hypothermia; metabolic acidosis, increased levels of lactate and hypernatremia. All calves recovered after alkalinizing fluid therapy and antibiotherapy. Halofuginone lactate was administered to some animals but it was not clear if it caused a major improvement in the recovery. In Portugal, 30 calves were examined in a fattening unit in the Ribatejo area concerning their clinical signs and presence of oocysts after modified Ziehl-Neelsen technique. Prevalence was high with 43% of animals showing oocysts in the faeces. Clinical signs varied and excretion was not always accompanied by diarrhea (assympthomatic carriers). Fifteen of the examined calves were reexamined one month later. Results varied greatly, evidencing on one hand the self-limiting character of the disease (3 calves improved) and, on the other hand, the possible connection of the disease to an increased mortality (2 calves died).

This thesis is concerned with how prehistoric infants were fed in different physical and cultural environments, and in particular what impact the economic, social, and epidemiological changes associated with the development of agriculture had on infant feeding practices. In order to examine these effects, stable isotope ratio analysis has been used to assess the duration of breastfeeding and weaning in a variety of prehistoric contexts. The first study is of Pitted Ware Culture hunter-gatherers at the site of Ajvide on Gotland, Sweden. Breastfeeding usually continued for at least two years, but there was some variation in supplementary foods, which is attributed to seasonal variations in resource availability. The second study analysed a number of Neolithic and early Bronze Age sites from south-east Poland. Breastfeeding duration varied both within and between sites and ranged from six months to five years. The third study found that the infant feeding practices of two Iron Age populations on Öland, Sweden, were very varied, and infants may have been fed differently depending on their social status. The fourth study is of the childhood diet in the Únětice Culture of south-west Poland. Individual diets changed little during the lifetime, suggesting that eventual adult identity was determined early in life. A small number of infants in the study were found to have breastfed for differing lengths of time. The final paper considers the health consequences of introducing animal milks into the infant diet in a prehistoric context, and finds that their availability is unlikely to have made it possible to safely wean infants earlier. Comparison of the results from the four stable isotope studies to those of other published studies reveals that the modal age at the end of weaning was slightly lower in agricultural communities than hunter-gatherer communities, but the range of ages was similar. Weaning prior to the age of eighteen months was rare before the post-medieval period. It is argued that the gradual reduction in breastfeeding duration since the Neolithic, and the replacement of breastmilk with animal milk products, means that on the whole the development of agriculture probably served to increase infant morbidity and mortality.

La mutation de souris weaver est une mutation recessive qui conduit a la mort d'un nombre restreint de cellules: cellules a grains du cervelet, neurones dopaminergiques nigrostries et cellules de sertoli testiculaires. Cette mutation est tout particulierement interessante puisque les neurones dopaminergiques nigrostries qui degenerent chez les souris mutantes sont homologues a la principale population neuronale detruite chez les malades atteints de la maladie de parkinson. La selectivite de la degenerescence des neurones dopaminergiques nigrostries a ete observee dans differentes situations experimentales d'atteinte du metabolisme energetique (souris injectees avec des inhibiteurs de la chaine respiratoire tels que le mptp, la metamphetamine) ainsi que dans la maladie de parkinson, dans laquelle des anomalies mitochondriales ont ete decrites. Ces observations suggerent l'existence d'une forte correlation entre selectivite de la degenerescence des neurones dopaminergiques nigrostries et deficit metabolique. En accord avec cette hypothese, nous avons montre que des neurones dopaminergiques nigrostries de souris saines sont plus sensibles et plus vulnerables que les autre types neuronaux a une atteinte de la phosphorylation oxydative induite par un inhibiteur de la chaine respiratoire. La mort cellulaire preferentielle des neurones dopaminergiques necessite l'activation du recepteur glutamatergique nmda qui, en provoquant une entree massive de sodium et donc en accentuant la consommation d'atp par la pompe na/k atpase, aggrave le deficit metabolique prealablement induit par la rotenone. Nous avons egalement mis en evidence l'existence d'un dysfonctionnement de la phosphorylation oxydative chez la souris weaver. Cette atteinte, bien que generalisee, permet de rendre compte de la selectivite de la degenerescence des neurones dopaminergiques, dont nous avons montre qu'ils sont naturellement plus vulnerables a une atteinte du metabolisme energetique. Elle peut aussi expliquer la diminution de la recapture de dopamine, activite consommatrice d'energie, que nous avons mise en evidence a un stade tres precoce, dans des cultures embryonnaires mesencephaliques weaver

Sociality and cooperation are universal features of life, yet cooperative societies are highly vulnerable to conflicts-of-interests which may lead to societal collapse. Dominance may function as a central mechanism behind the maintenance of cooperative societies, because it may reduce conflict by the establishment of hierarchies, and may act in concert with kin selection, enforcement or signalling mechanisms to promote cooperation. Yet, the significance of dominance in the evolutionary routes that maintain cooperation remains poorly understood (Chapter 1). Sociable weavers Philetairus socius are highly social, cooperative passerines. The species is particularly prone to conflicts because of their year-round coloniality and thus year round sharing of resources. Using extensive field-data on individual behaviour, I examine in this thesis whether dominance may mitigate conflict and maintain cooperation, and how it may inform our understanding of the evolutionary mechanisms underlying cooperation. In Chapter2, I investigate whether hierarchies and phenotypic traits allowing the assessment of social status may have evolved to mediate conflicts. I show that weavers establish ordered hierarchies within colonies and that the size of a melanin-based plumage trait, the black bib, is correlated to social status. In Chapter 3, experimental manipulation supports my proposition of a status signalling function of the bib. In Chapter 4, I investigate the benefits of achieving high social status and whether these are shared with relatives through nepotism. Both dominants and their offspring gain enhanced access to resources. Dominants had more access to breeding positions, although this was not reflected by increased reproductive success. In Chapter 5, I explore how dominance and kinship predict individual cooperativeness to three tasks, nestling provisioning, nest construction and predator mobbing. I find that both explain variation in cooperativeness, yet some results follow opposite directions, revealing multiple routes to cooperation. Finally, in Chapter 6, I examine how dominance and kinship structure weavers' social network and whether network position are linked to cooperativeness. Social network analyses reveal that more central birds are more, related, dominant and cooperative. Chapter 7 concludes that dominance acts in concert with kinship to promote the societal lifestyle of sociable weavers highlighting the potential significance of dominance in the evolution of cooperation.
