Dana, Dan. "Enjeux et controverses autour du mythe de Zalmoxis." Paris, EHESS, 2005. http://www.theses.fr/2005EHES0071.
Full textAbstract:
La thèse analyse le destin et les interprétations autour de la figure de Zalmoxis, dieu des Gètes (population thrace du Danube inférieur), depuis les Histoires d'Hérodote jusqu'à nos jours. Reposant sur l'analyse du cadre historiographique et du contexte idéologique de chaque époque, dans une vision comparatiste, le réexamen critique des théories formulées à son propos présente une importance exceptionnelle. Analyser les traditions antiques, médiévales et modernes au sujet de Zalmoxis conduit à s'interroger sur les différents enjeux suscités par ce personnage, en Occident comme en Roumanie, pays dans lequel il joue un rôle majeur dans la définition du "spécifique national", et la construction d'un passé prestigieux. Une autre dimension du sujet est l'histoire du personnage de Zalmoxis dans la culture roumaine moderne ( son appropriation par le nationalisme historique), ainsi qu'une critique de la monographie de Mircea Eliade. L'histoire de Zalmoxis à travers les époques nous informe moins sur son culte réel, que sur les auteurs et les porteurs de son motif, sur les divers prétextes de son usageThe thesis examines the destiny and the interpretations around the figure of Zalmoxis, god of the Getae (Thracian population on the Lower Danube), since the Histories of Herodotus to our days. On the grounds of the analysis of the historiographical frame and the ideological context of every epoch, in a comparative vision, the critical reexamination of the theories about this subject presents an exceptional importance. The analysis of the ancient, medieval and modern traditions concerning Zalmoxis leads to questioning about the different stakes generated by this personage, in Occident as well as in Romania, country wheere he plays a major role in the definition of the "national specific" and in the construction of a prestigious past. Another dimension of the subject is the history of the personage of Zalmoxis in the modern Romanian culture (his appropriation by the historical nationalism), including a critique of Mircea Eliade's monograph. The history of Zalmoxis across the ages teach us nothing about his real cult, but a lot about the authors and the bearers of his motif, on the various pretexts of his use

En l'absence de toute synthèse sur l'architecture romaine de la Dacie, la présente étude a pour but d'offrir une vision d'ensemble sur tous les types de monuments découverts dans cette province. La plupart d'entre eux ont été construits dans la dernière moitié du II-e s. Ap. J. C. Et refaits pendant l'époque sévérienne. Le décor monumental témoigne de l'existence de plusieurs ateliers locaux, très actifs à cette période, mais aussi de celle d’artisans pérégrins venus surtout des provinces orientales de l'empire. Les travaux se sont déroules sous le patronage d'évergètes locaux qui en ont assuré personnellement le financementAs it didn't exist until now a synthesis regarding the roman architecture of Dacia, the present work offers a general picture on the principal monuments discovered in this privince. The major part of them were built during the last half of the II-nd century A. C. , and restored at the severian period. The monumental decoration attests the activity of many local workshops, very well-known at that time, but also the presence of some workmen coming from the oriental provincies the works were increasily developed by some local patrons on their own expenses

Le fait religieux est un phénomène constant dans le monde militaire de la Rome impériale. Il fut essentiel pour les troupes qui participèrent à l'annexion de la Dacie. La période comprise entre la chute du royaume de Décébale sous les assauts de Trajan et la retraite décidée par Aurélien permet d'identifier dans le cadre d'une histoire régionale l'évolution de croyances perceptibles à l'échelle de l'empire. Cette reconstitution est possible grâce à des centaines de témoignages épigraphiques, archéologiques, mais également iconographiques, numismatiques et littéraires. L'esprit de corps, la propre identité et la loyauté envers la hiérarchie étaient consolidés en permanence, par des cérémonies officielles auxquelles prenaient part les unités, les commandants et les soldats, à l'intérieur des camps. Or les individus honoraient aussi de nombreuses autres divinités romaines ou étrangères, dans les baraquements ou dans des sanctuaires extérieurs. Leur piété était motivée par des soucis de salut, de santé et de protection. La richesse et la variété exceptionnelles des manifestations cultuelles de cette armée stationnée au nord du Danube s'expliquent par ses origines très diverses et sa formidable capacité d'assimilationThe religious fact is a constant phenomenon in the military world of imperial Rome. It was essential for the troops participating in the annexation of Dacia. The period between the fall of Decebalus' kingdom besieged by Trajanus and the withdrawal decided by Aurelianus allows us to identify the evolution of religious beliefs which can be recorded on the scale of the Empire within the framework of regional history. This reconstruction is possible thanks to hundreds of epigraphic and archeological testimonies, but also thanks to iconographical, numismatic and literary testimonies. The team spirit, one's identity and loyalty towards hierarchy were constantly strengthened through official ceremonies in which the military units, their commanders and their soldiers took part inside the camps. The individuals also worshipped many other Roman or foreign gods in their on camp barracks or in the off camp sanctuaries. Their piety was due to the concerns for their preservation, good health and protection. The outstanding richness and variety of the worship forms displayed by the army stationed in the north of Danube can be explained by their very diverse origins and its exceptional capacity of assimilation

Full textAbstract:
The idea of corruption travels down and supports this thesis. It stands as one of the principal stakes of the Homeric Quarrel. By analysing it, we may deepen our understanding of the value the famous hellenist Anne Dacier placed on the heritage of the Anciens and its reception by the Moderns; we may also better understand in which ways her engagement in polemics belonged to her times. Anne Dacier was less an apologist of Homer than a polemist who attacked the corrupted taste of her contemporaries. She feared for them, but above all, she feared for the Homeric text. She had done her best in her translation to preserve the poem while Houdar de la Motte, her adversary thought that an adaptation would suit the public better. Mme Dacier presented herself as the guardian of tradition and its purity; nonetheless, to achieve her goal, she had to compromise with her opponents and speak their corrupted language.

Full textAbstract:
The aim of this study is to make a comparative study between the grievances during the Dacke Warand the German Peasant´s War. These two conflicts may have occurred separately, regarding bothgeographical and chronological distances but also share common issues for this comparative study.Less than two decades separates these two conflicts and they were all by their own serious insurrectionsduring their time. While the German Peasant´s War was the greatest uprising in Europe up tothe French Revolution, the Dacke War was the biggest Peasant Rebellion in Scandinavian history.While the German Peasant War has been studied and researched by historians for a relative longtime, the Dacke War has been neglected in research history. If it were not for the Swedish professorLars-Olof Larsson’s studies during foremost in the 1960s, the Dacke War would have been a historicallyuncharted territory of research indeed. This study aims to foremost supplement the unsatisfiedresearch on the Dacke War, but also supplement the research of The German Peasant war, with thiscomparative study. Although is exists a somewhat considerable amount of studies and theories regardinggeneral peasant uprisings and revolts from this period, researchers are still debating themain causes for these violent conflicts. The combination of different geographical and social differencesand insufficient sources makes studies about theses conflicts both problematic and complex.The result of this comparative study, show that both uprisings shared both common and differentkinds of grievances where generally the rebels of the German Peasant´s War had a larger propotionof demands than the rebels of the Dacke War. In Sweden the grievances was largely made up bycomplaints. While the German Peasant´s War was generally more radical and religious motivatedthan the Dacke War, it shared many similarities to each other, especially when it came to economicand economical complaints. While the German Peasants (although not all rebel-groups) made radicaldemands, such as the abolishment of serfdom, the rebels during the Dacke War were more intenton restoring their former rights and customs. Therefore the Swedish peasantry motivated theircomplaints by claiming they had juridical rights and legal claims to motivate rebellion. The Germanpeasants on the other hand, although also sharing the same motives but in somewhat lesser degree,had less legal rights and therefore motivated their demands in religious terms. The reason why thegrievances during the Dacke War mostly can be categorized as complaints instead of demands, maybe explained how influential and political equal the Swedish peasants were as a social group and estatein Swedish society compared to the many peasants living in serfdom in the Holy Roman Empire.This is also why German rebels more often legitimized their demands with religious motive,because they lacked the political power as social group and estate.

Full textAbstract:
Parmi les provinces romaines, la Dacie, par son emplacement aux confins des civilisations grecque et latine, a abrité une population cosmopolite, caractérisée par le multilinguisme et le multiculturalisme, pour laquelle le latin et le mode de vie romain ont joué un rôle de catalyseur. En l’absence des investissements coûteux dans les projets archéologiques, l’onomastique a su suppléer avec succès les résultats des fouilles, en fournissant un matériel fertile qui complète le tableau historique de la province et qui redonne une image assez fidèle de ses habitants. L’essor des études onomastiques dans l’après guerre, la transformation de l’onomastique de science auxiliaire de l’histoire en science autonome, s’est traduit en Roumanie par une série d’enquêtes qui essayent de reconstituer, au moins partiellement, des anciennes langues aujourd’hui disparues (l’illyrien, le thrace) à partir de leurs uniques vestiges : les noms propres. Suivant la tradition de l’époque, les ouvrages désormais classiques de I. I Russu ne retiennent que les aspects linguistiques, la morphologie et l’étymologie des noms, dans l’esprit des études indo-européennes qui dominaient alors l’historiographie occidentale. Dans ce sillage, les auteurs qui ont suivi, ont adopté la même perspective philologique qu’ils ont enrichie plus récemment par des études prosopographiques, mais leurs travaux restent ponctuels, limités à une certaine communauté ethnique, à une catégorie sociale ou bien à la population des grandes villes. De là naît le besoin d’un projet plus étendu qui porte sur l’ensemble de la province et qui, tout en tenant compte du caractère interdisciplinaire de l’onomastique, traite à la fois de la position des noms dans le système de la langue et des aspects légaux, politiques et sociaux révélés par les anthroponymes. Dans cette thèse je vise à étudier, de manière critique et détaillée, l’anthroponymie de la Dacie Romaine, en complétant l’enquête prosopographique tournée vers les aspects sociaux par une approche philologique. Les deux jalons chronologiques que j’ai choisi pour encadrer mon ouvrage, seront l’an 106, la date de la défaite des Daces face à Rome, comme terminus post quem, et 271 année qui marque conventionnellement la fin du gouvernement romain en Dacie.L’onomastique de la Dacie est marquée par des influences multiples : influence politique (gentilices ajoutés), religieuse (théophores), ethnique (noms « barbares), influence du milieu militaire (noms latins), de la culture classique (noms grecs), des pratiques étrangères (noms celtes). Il n’y a pas une influence dominante, pareil à la romanisation, l’onomastique telle qu’elle nous a été conservée est un produit entièrement nouveau, née de l’intersection de tous les usages que les habitants de la province ont fait des nomsBy virtue of its location on the borders of Latin and Greek civilizations, Dacia, one of the Roman provinces, housed a cosmopolitan population. This cosmopolitanism was characterized by multilingualism and multiculturalism, with the Latin language and the Roman lifestyle acting as catalysts. Despite the absence of much investment in archaeological projects, onomastic studies successfully compensated for the lack of excavation. Onomastics provided rich material, filling in the historical picture of the province (the history of the province), and giving a fairly accurate impression of its inhabitants. The sudden growth of onomastic studies in the postwar period and their transformation from an ancillary science of history to a science in its own right, was reflected in Romanian historiography in a series of studies that attempted to reconstruct ancient languages (Illyrian, Thracian), at least partially, through their unique remains: proper names. The classic work of I.I. Russu focuses only on linguistic aspects, morphology and etymology of names, following the scientific practice of the time, in the wake of the domination of Western historiography by Indo-European studies. The followers of this line of investigation continued to adopt a philological perspective, which has been recently enriched by a prosopographic approach. Yet, such investigations remain limited to a specific ethnic community, a social group or the population of large cities. Hence the need for a larger project that studies the onomastics of the whole province, and (given the interdisciplinary nature of onomastics) that investigates the position of a name in a language as well as the legal, political or social aspects revealed by anthroponyms. In this thesis I study, in a detailed and critical manner, the onomastics of Roman Dacia, and to the prosopographical investigation, usually oriented toward social aspects, I add a philological perspective. The two chronological milestones that I have chosen for my study are 106 A.D., the date of the final defeat of the Dacians as terminus post quem, and 271 A.D., the conventional date marking the abandonment of the Dacian provinces as a case of terminus ante quem.Dacian onomastics is marked by multiple influences: political (added gentile names), religious (theophoric names), ethnic ("barbarian" names), and the influences of the military milieu (Latin onomastics), of classical culture (Greek names) and of foreign onomastic practices (Celtic names). There is no single dominant influence: in the form in which it has been preserved, onomastics, like Romanization, is a completely new product, born at the intersection of all the uses that the inhabitants of the province gave to proper names

Full textAbstract:
Boèce de Dacie est un philosophe du 13e siècle, connu comme modiste et « averroïste ». Notre thèse consiste à donner une interprétation exacte de la 16e question de ses Modi significandi, un texte philosophico-grammatical, où l'auteur développe un certain innéisme linguistique. Selon certains chercheurs contemporains, par cet innéisme, Boèce est considéré comme précurseur du nativisme de Noam Chomsky. Selon d'autres, cet innéisme n'a pas de valeur théorique importante dans la philosophie de Boèce. Boèce souligne plutôt l'ancrage du langage dans la structure des choses, et de ce point de vue, sa position n'a pas de particularité à l'époque. Selon notre analyse, ce sont deux versants du même naturalisme : tout doit être expliqué par sa propre nature. Par là, Boèce minimise le rôle de la volonté dans l'institution des langues et à la place de la volonté humaine, il introduit la nature humaine, qui est comparable à la nature de n'importe quelle espèce animale, comme le fondement des sciences du langage. Pour bien fonder cette interprétation de la théorie de Boèce, nous remontons au douzième siècle et analysons le texte de Gundissalinus, qui forme un horizon pour les auteurs du treizième siècle ; nous comparons la théorie de Boèce avec celle d'un contemporain Michel de Marbais qui insiste sur le rôle de la volonté ; nous la comparons aussi avec celles de Siger de Brabant ou des anonymes en lisant les manuscrits qui nient pour la plupart la position de Boèce de Dacie et reprennent la position plus traditionnelle. Boèce n'est jamais un précurseur de Chomsky, mais un auteur particulier à l'époque par son naturalisme linguistique ayant deux versantsBoethius of Dacia is a 13th-century philosopher, known as a modist and "averroist". In this thesis, we intend to give an exact interpretation of the 16th question of his Modi significandi, a philosophico-grammatical text, where the author develops a certain linguistic innateness argument. Some modem scholars consider him, by this innateness argument, as a precursor of Noam Chomsky's nativism. Others believe that such an innateness argument is not theoretically important for his linguistic philosophy. Boethius rather emphasizes the anchoring of language in the structure of things, and for this argument, his position isn't so peculiar at the time. According to our analysis, these are two sides of the same naturalism: everything must be explained by its own nature. From this point of view, Boethius minimizes the role of the human will in the constitution of language and instead of the human will, he introduces, as the foundation of the linguistics, the human nature, which is comparable to the nature of any other animal species. To establish this interpretation of Boethius's theory, we go back to the 12th century and analyze the text of Gundissalinus which gives a horizon for the authors of the 13th century; we compare the theory of Boethius with that of a contemporary Michel de Marbais who emphasizes the role of the will; we also compare it with those of Siger of Brabant or anonymous authors, in reading manuscripts. The majority denies the position of Boethius of Dacia and chooses to renew more traditional positions. Boethius is not a precursor of Chomsky, but a very particular author at that time by his two sided linguistic naturalism.

Brook, Alison J. "The environmental control of reproduction in the female dace, Leuciscus leuciscus." Thesis, Aston University, 1989. http://publications.aston.ac.uk/10566/.
Full textAbstract:
An investigation was made into the nature and control of the annual reproductive cycle of the dace, Leuciscus leuciscus. It includes 1) a study of the natural reproductive cycle, 2) the use of Carp Pituitary Extract (CPE) to induce final maturation and ovulation in captive fish, 3) the effect of artificial light treatments on ovarian development and 4) the measurement of serum melatonin levels under different photoperiod regimes. Ovarian development was monitored by endocrinological data, notably serum cycles of 17-oestradiol (E2), testosterone (T), and calcium (as an index of vitellogenin), oocyte diameter, the gonadosomatic index and histological studies of the ovary. Under natural conditions, ovarian development can broadly be divided into 4 stages: 1) oogenesis which occurs immediately after spawning; 2) a primary growth phase (previtellogenic growth) prevalent between spawning and June; 3) a secondary growth phase (yolk vesicle plus vitellogenic growth) occurring between June and December and 4) final maturation and ovulation which occurs in mid-March. During the annual ovarian cycle, the sex steroids E2 and T showed two clear elevations. The first occurred initially in April followed by a rise in serum calcium levels. This subsequently initiated the appearance of yolk granules in the oocytes in June. The second rise occurred in September and levels were maintained until December, after which there was a decline in serum E2 levels. It is proposed that in the dace, high serum E2 levels between September and December were required to maintain vitellogenin production and therefore its uptake into the developing oocytes which occurred during this time, albeit at a slower rate than in the summer months. After December, prior to final maturation, whereas serum E2 and calcium levels declined, serum T levels remained elevated. In captivity, final maturation beyond the germinal vesicle migration stage failed to occur suggesting that the stimuli required for these events were absent. However ovulation could be induced by a single injection of CPE, which induced ovulation between 6 and 14 hours after treatment. Endocrine events associated with the artificial induction of spawning included a rise in serum levels of E2, T and the maturation inducing steroid 1720-dihydroxy progesterone. Photoperiodic manipulation demonstrated that whereas short or increasing daylengths were stimulatory to ovarian development, long days delayed development. Changes from long to short and constant short daylengths early in the reproductive cycle advanced maturation (up to 5 months), suggesting that the stimulus for ovarian development and maturation was a short day. However, experiments conducted later in the reproductive cycle demonstrated that only a simulated ambient photoperiod could induce final maturation. It is proposed therefore that under natural conditions the environmental stimulus for ovarian development and final maturation are short and increasing daylengths respectively. Further support that photoperiod is the dominant timing cue in this species was provided by the pattern of serum melatonin levels. Under different photoperiod treatments, serum melatonin, which is believed to be the chemical transducer of photoperiodic information (similar to other photoperiodic species) was elevated for the duration of the dark phase, indicating that the dace at least has the ability to `measure' changes in daylength.

Full textAbstract:
Clinch Dace (Chrosomus sp. cf. saylori) is a newly recognized species of minnow with a restricted distribution in southwestern Virginia. Field sampling and genetic analysis support the hypothesis that Clinch Dace populations are small and fragmented. Analysis of neutral genetic markers shows that most Clinch Dace populations have undergone past bottleneck events and are being operated upon by random genetic drift. Bayesian cluster analysis showed that three out of the seven populations found in 2017 are distinct, while the other four show signs of more recent admixture. However, Fst values among streams were high and analysis of molecular variance indicated differentiation among populations in all streams. These findings support the view that these populations are genetically isolated. Effective populations sizes were low at most sites, enhancing the likelihood of loss of alleles to genetic drift. Low M-ratios, non-zero Fis values, and high degrees of relatedness among individuals indicate that some inbreeding is taking place. Habitat analysis did not identify variables affecting distribution or abundance of Clinch Dace populations. As the collection sites were targeted near known Clinch Dace occupied sites, it is likely that habitat variables known to impact Clinch Dace, such as conductivity, were within the species' range of tolerance. Results showed that Clinch Dace seem particularly resilient to sedimentation, corroborating earlier work showing a negative relationship between Clinch Dace abundance to sediment size. That is, small sediment size does not seem to have a negative impact on Clinch Dace abundance. Of all sites where Clinch Dace were found, only one culvert at one site was clearly perched and may present a barrier to upstream migration, a possibility which is supported by the genetic differentiation found among collections above and below that culvert. While this study demonstrates that selectively neutral genetic differentiation has taken place among Clinch Dace populations, it does address any local adaptation that may be taking place which would render translocations a risk for outbreeding depression. The findings of this study can inform conservation management in identifying possible sources of individuals for translocations among populations or for augmentation following captive breeding.Master of Science
The Clinch Dace is a small, threatened minnow in the Clinch River basin that was unknown until 1999. Since then, research has addressed the biology, life history, and distribution of this fish. This study used data from selectively neutral genetic markers to analyze the population structure and degree of differentiation of Clinch Dace populations. My study sites were targeted at road crossings near known Clinch Dace populations to assess the effect of habitat fragmentation on Clinch Dace populations and to maximize the likelihood that I would collect enough genetic material for analysis. Genetic analyses showed that while there is some admixture among certain populations of Clinch Dace, there is differentiation at neutral genetic markers. This differentiation does not necessarily indicate adaptive variation among populations which could result in outbreeding depression should populations be mixed through translocations, but it is reason to proceed with caution. Road crossings were generally not found to be a cause of further population fragmentation in Clinch Dace, as demonstrated by genetic analysis and statistical analysis. Almost all of the occupied road crossing sites in this study were either embedded, free-flowing culverts that were not perched or small bridges, and these were not deemed to be obvious barriers to fish movement. The only exception was Hart Creek 2, where the culvert is slightly perched and Fst is high between populations in the upstream and downstream reaches. The results of this study will help to inform managers as to what conservation actions can be taken to improve population viability. One potential management action from this study could be the retrofitting of culverts that have become perched and are acting as barriers to Clinch Dace movement. Another potential conservation strategy is to translocate individuals from large population to small populations. The study determined: 1) which translocations might be acceptable based on the degree of genetic differentiation among populations, and 2) identified potential donor and receiving streams for translocations.

Full textAbstract:
Rhinichthys osculus, the Speckled Dace, is one of the most ubiquitous fish in western North America. Within the Southern California region, the local taxon is known as the Santa Ana Speckled Dace. The purpose of this study was to characterize and identify polymorphic microsatellite markers for R. osculus in which twenty-three were identified through Illumina pair-end sequencing. Seven of these loci were then used to examine the patterns of genetic variation and population structure that occurred within and among the watersheds in the Southern California. The study also examined the regional relationships among Southern California, Central California and Owen’s River Valley. Analysis of the microsatellite data revealed highly significant moderate levels of population structure exist within the Southern California region (RST=0.160, p=0.001). This structure is best explained by watershed as well as isolation by distance (R2=.2286, p=0.010). Highly significant geographic structure also exists among the geographic regions of Southern California, Central Coast, and Owen’s River Valley regions (RST= 0.600, p-value=0.001) that are congruent with the regional differentiation elucidated by mtDNA sequence data. In both cases, the degree of population differentiation was correlated with isolation by distance. Utilizing this information we were able gain a better understanding of the evolutionary relationships among the Southern California populations of Santa Ana Speckled Dace. Within the Santa Ana Speckled Dace populations we examined four models to explain the geographic structure: watershed, mountain range, tributary, and isolation by distance. While all were significant, the tributary model exhibited the higher level of population structure (RST= 0.160, p-value=0.001) and a significant correlation was exhibited between geographic distance and population structure, suggesting isolation by distance may be playing a role. The results of the microsatellite analysis are congruent with an earlier broad scale analysis of mtDNA sequence data that suggests the Central California and the Owens Valley populations diverged from each other prior to the divergence of the Santa Ana Speckled Dace populations from the Colorado Basin populations, and that the Central Coast populations were not established as a result of a migration event from the Southern California populations, as was previously hypothesized. Primarily due to human activity, Santa Ana Speckled Dace habitat has become highly fragmented resulting in some populations becoming extirpated. We hope this study will guide the strategies for the conservation of the remaining populations of Santa Ana Speckled Dace and watershed management in Southern California.

À travers l'étude de 166 monuments, nous avons tenté de définir les schémas architecturaux en usage entre le IVe et le VIe siècle dans ces régions. Nous nous sommes intéressée à la diffusion des types architecturaux et à la nature des influences qui s'exercent sur l'architecture chrétienne au nord des Balkans. Notre corpus laisse entrevoir une tendance à l'uniformité qui s'inscrit dans une koinè architecturale méditerranéenne. Au-delà des modèles architecturaux, nous i nous sommes attachées aux dispositifs liturgiques, à leur répartition géographique, à leur typologie, mais également à leur adaptation et exportation dans un cadre régional et supra régional. L'archéologie apporte des jalons précieux sur la définition des «provinces liturgiques», car à part différence du plan, l'équipement liturgique du monument obéit plus aux ressorts ecclésiastiques.

Full textAbstract:
The dace (Leuciscus leuciscus (L.)) is a small, shoaling, rheophilic, lithophilic cyprinid fish, and is an important component of chalk stream ecosystems. Historical recaptures of marked dace in the River Frome suggested that some individuals were mobile, however it was unclear whether these movements occurred predictably in time or space. Migrations, defined as deliberate, temporally predictable translocations in space, allow individuals to exploit new resources, avoid predators and find a mate. However, energy is generally utilised during locomotion, and there are potential costs associated with moving to an unfamiliar environment, including reduced foraging opportunities, and increased predation risk. To be successful, individuals must find food, avoid predation and reproduce. If adult dace can solve these problems efficiently in one section of river, then considering the potential costs associated with migration, it would be most profitable for them to remain in this area. A range of techniques were used to study the migrations and habitat use of adult dace in the River Frome, covering both daily and seasonal cycles. The movements of 32 radio-tagged dace were tracked over a period covering over 16,000 hours. During this period 6864 radio locations were made, and radiotagged fish covered a combined minimum distance of over 109 km. A further 1724 dace were individually or batch marked, of which 128 were recaptured. In addition over 4000 dace were recorded on video as they passed through a fish counter. The daylight habitat use of 377 adult dace was visually observed from the bank, and habitat suitability indices created. The nocturnal habitat use of 11 adult dace was assessed using radio-active isotope tags, which were located on 247 occasions over a period covering 121 "fish nights". The adult dace observed in this study moved extensively, and their movements were both temporally and spatially predictable, and therefore constituted migrations. Of the 30 fish released at their capture sites, at least 19 moved more than 500m fi-om this site during the observation period. Spawning occurred in millstreams, and was preceded by an upstream migration. After spawning, slow flowing shaded sites out of the main river were selected by at least five out of six radio-tagged dace. A substantial upstream migration was observed in late spring, and diel migrations between separate distinct day and night habitats were observed during the summer. In autumn adult dace moved downstream and formed aggregations in the tidal reaches. Consequently, the hypothesis that dace occupy one section of the river throughout the year was rejected.

Full textAbstract:
The purpose of this project was to examine carefully how the arts (music, mime, dance, and drama) could potentially enhance the spirituality of youth between the ages of 13 and 19. The researcher’s aim was to use the arts to make the stories and messages of the Bible come “alive” in a creative and innovative manner. Afler meeting with a select group of leaders on August 27, 2009, regarding the needs of the youth, the researcher moved forward with the assurance of membership support regarding the proposed Doctor of Ministry of Project based on the arts. Throughout the process, the researcher used every opportunity available to capture and evaluate dramatic presentations at the Greater Solid Rock Baptist Church. The span of the Doctor of Ministry Project lasted seven months (April-October 2011), with six activities in the form of dramatic presentationsbeing conducted over that period of time. In this document, the author gives the reader detailed information regarding the process used to reach the researcher’s final destination. Below are brief highlights from each chapter in order to give the reader a general sense of the process used to compile and complete information relative to the Doctor of Ministry Project. Chapter I gives the reader a general introduction to each succeeding chapter in this document. Although the information in the introductory chapter is not presented in detail, the author provides key points regarding material appearing subsequently. Chapter II focuses on the Ministry Context/Issue, primarily on the demographics of the Greater Solid Rock Baptist Church and related social statistics. Chapter III explores the Biblical literature that informs the Doctor of Ministry project, identifying key scriptures that relate to youth and how youth are able to overcome obstacles in life. Chapter IV shines the light of research on theological literature, mainly focusing on how Biblical characters such as Goliath can be re-imagined as social influences such as drugs, sex, and alcohol. Key statistics are given regarding the use of these elements by our youth (ages 13-19) before marriage and how this use is impacting their education and spiritual development. Chapter V provides empirical and theoretical information to support the researcher’s position regarding using the arts to enhance the spirituality of the youth, along with professional statements from artists and teachers in the arts espousing this position. Chapter VI focuses on the actual Doctor of Ministry Project and all that went into making this project a success, offering a “How To” listing for coordinating, producing, and directing an arts program/play in the local ministry setting. Finally, in Chapter VII the researcher reflects on the entire process and shares final statistics from evaluation of the surveys submitted to the congregation during each dramatic presentation or activity connected with the Doctor of Ministry Project.

Full textAbstract:
Fish passage success rates through hydraulic infrastructure have been historically low due to flow field conditions that exceed the physical or behavioral capabilities of a given species. Significant efforts to design and modify hydraulic structures for enhanced passage rates have failed to achieve the desired results, with a primary reason being a poor understanding of how fish respond to complex hydraulic conditions. Many contemporary research efforts have targeted the inter-relationship between hydraulics and fish behavior in the laboratory using live fish trials in an attempt to better comprehend these interactions and ultimately provide a basis for the development of biologically-based design criteria. In this study experiments were conducted to assess the behavioral responses along swimming trajectories of western blacknose dace ( Rhinichthys obtusus) in turbulent flow conditions. The objective was to test the hypothesis that the dace would preferentially adjust their swim paths to minimize their exposure to elevated turbulent conditions. Experimental data were collected through digital imaging of dace trajectories for fish that had been released into a shallow flume and allowed to swim through turbulence enhanced flow fields. Additionally, detailed velocity measurements were collected with an acoustic Doppler velocimeter to allow the comparison of dace trajectories to flow field conditions represented by average metrics of turbulent kinetic energy and Reynolds shear stresses. Analysis of the data consisted of the quantification of the proportion of the time that a dace's swim path selected a direction toward a lower magnitude turbulence condition when such an option existed. Fish paths were also graphically compared to turbulence contour plots to qualitatively assess the presence of swim path preferences or patterns. Lastly, video footage of each trial was evaluated to qualitatively assess the presence of novel behaviors that could have implications for the swimming trajectories observed. Results indicate that the dace did not preferentially avoid turbulence at statistically significant levels under the conditions experienced in the flume; however, data do suggest that some behavior relative to turbulence was non-random. Qualitative observations of video footage suggest that non-hydraulic factors, such as the presence of conspecifics and light intensity, also influence the swim path trajectories of the western blacknose dace. Future research will require more targeted turbulent conditions, simultaneous multivariate observations and analyses that factor in non-hydraulically-based behavior and the incorporation of coupled behavioral and hydraulic data at reduced time and length scales for primary variables. It is envisioned that the results of this study can provide guidance for future studies aimed at developing biologically based design criteria for enhanced fish passage at hydraulic infrastructure.

Full textAbstract:
The purpose of this genetic study of the Santa Ana Speckled Dace Rhinichthys osculus was three-fold. The first goal was to characterize the molecular structure of the mtDNA control region of R. osculus. An 1143 base-pair region of the mitochondrial DNA genome, which included the complete control region was sequenced for all individuals. Analysis of the sequence data revealed that the molecular structure of the speckled dace control region was similar to the molecular structure described for other vertebrate taxa. The speckled dace control region contains three major domains, which vary in base frequency as well as in the frequency of nucleotide polymorphisms. Domain II was observed to be the most conserved, and Domain I was the most variable domain of the control region, in agreement with studies of other vertebrate control regions. The second goal of this study was to ascertain the phylogeny of R. osculus in Southern California in relation to other speckled dace in California. Seventy-four specimens of R. osculus were collected from five different watersheds located in three geographic regions of California: Southern California, the Central California Coast, and the Eastern Desert of the Owens River valley. Phylogenetic analysis of sequence data revealed that the Santa Ana Speckled Dace is a genetically distinct population from R. osculus inhabiting the Central Coast or Eastern Desert regions, which both differ from the Santa Ana Speckled Dace by a genetic distance of more than 7 percent. The Santa Ana Speckled Dace inhabiting the watersheds of Southern California form a reciprocally monophyletic clade with respect to the Central Coast dace and the Eastern Desert dace, which are sister clades to one another. The third goal of this study was to describe the population genetics of R. osculus in Southern California. Population genetic analysis demonstrated that a high degree of geographic population structure exists for the Speckled Dace in California, with 96% of molecular variance attributable to regional differences through isolation by distance. A high degree of population structure also exists among populations within the Southern California region as well. It was found that 45% of molecular variance in the Santa Ana Speckled Dace is attributable to differences among tributaries. This study finds that the distribution of speckled dace in Southern California best fits a model of population structure by individual tributary, with episodes of localized population bottlenecks followed by sudden population expansion, most likely linked to climatic variation. It is proposed the Santa Ana Speckled Dace constitutes an Evolutionarily Significant Unit (ESU) that qualifies it as a separate subspecies on the basis that it is geographically separated from other populations, genetically distinct from other dace populations due to restricted gene flow, and possesses unique phenotypic characteristics. This information suggests conservation and management strategies for the speckled dace populations which remain in existence in Southern California.

Full textAbstract:
The Clinch Dace Chrosomus sp. cf. saylori is a species of minnow known from only two counties in Virginia. Prior surveys established the species' presence in just eight tributaries to the upper Clinch River. A management plan, which should include both population monitoring and habitat restoration, is still lacking for the species. Population monitoring must balance high detection probability with low risk of injury to captured individuals. I sampled 98 sites in 2014 and 2015 within the putative range of Clinch Dace to refine estimates of its distribution. I sampled 70 of the 98 sites with multiple gears and replication in an occupancy modeling framework. Clinch Dace occupied low-gradient headwater streams with relatively low conductivity in forested watersheds. My surveys uncovered two new tributaries occupied by Clinch Dace, and I was unable to find Clinch Dace in two historically occupied streams. Species detection probability was higher with backpack electrofishing than minnow trapping. N-mixture models suggest that Clinch Dace are more abundant in watersheds with high forest cover although forest cover is highly correlated spatially in the nested stream network. Density estimates from mark-recapture sampling suggest that Clinch Dace occur at low densities in approximately 31.5 km of headwater streams. The mean estimate of global population size was 6,706 individuals. Some populations could be affected by low genetic diversity. I conclude by developing a prioritization framework for restoration and protection of 15 candidate conservation areas. Managers should work with private landowners to implement best management practices in high priority watersheds.Master of Science

Complex mathematical models are often built to describe a physical process that would otherwise be extremely difficult, too costly or sometimes impossible to analyze. Generally, these
models require solutions to many partial differential equations. As a result, the computer
codes may take a considerable amount of time to complete a single evaluation. A time tested
method of analysis for such models is Monte Carlo simulation. These simulations, however,
often require many model evaluations, making this approach too computationally expensive.
To limit the number of experimental runs, it is common practice to model the departure as
a Gaussian stochastic process (GaSP) to develop an emulator of the computer model. One
advantage for using an emulator is that once a GaSP is fit to realized outcomes, the computer
model is easy to predict in unsampled regions of the input space. This is an attempt to 'characterize' the overall model of the computer code. Most of the historical work on design and analysis of computer experiments focus on the characterization of the computer model over
a large region of interest. However, many practitioners seek other objectives, such as input
screening (Welch et al., 1992), mapping a response surface, or optimization (Jones et al.,
1998). Only recently have researchers begun to consider these topics in the design and analysis of computer experiments. In this dissertation, we explore a more traditional response
surface approach (Myers, Montgomery and Anderson-Cook, 2009) in conjunction with traditional computer experiment methods to search for the optimum response of a process.
For global optimization, Jones, Schonlau, and Welch's (1998) Efficient Global Optimization
(EGO) algorithm remains a benchmark for subsequent research of computer experiments.
We compare the proposed method in this paper to this leading benchmark. Our goal is to
show that response surface methods can be effective means towards estimating an optimum
response in the computer experiment framework.Ph. D.

Full textAbstract:
In this study, I sequenced the mitochondrial cytochrome b gene to elucidate the extent and pattern of genetic variations among and within populations of Rhinichthys osculus (Santa Ana Speckled Dace) found in the different watersheds in Southern California, Central California Coast and Eastern California Desert. I described and analyzed the structural characteristics and pattern of base sequence substitutions in the cytochrome b gene to understand the molecular evolution of the gene. The Phylogenetic analyses showed that the Southern California Santa Ana Speckled dace is a distinct population from the Central California Coast dace population and Eastern California Desert dace population, and is more closely related to the Colorado River speckled dace population. There is a high degree of genetic variation among all populations including a significant genetic structure associated with watersheds, mountain ranges, and geographic grouping based on locations. The SWISS-Model automated protein structure homology elucidated the conserved and invariant residues within the cytochrome b gene where the amino acid substitutions are located in the trans-membrane of the protein sequence. The implication for conservation and management of the Southern California Santa Ana Speckled dace is high because of habitat lost for this distinct dace population. The data from this study will contribute to preserving the genetic variability of the Santa Ana Speckled Dace as a separate taxa and species, as well as to help maintain intact the population in the different Southern California creeks.

Full textAbstract:
Rhinichthys osculus (Cyprinidae), the speckled dace, is the most widely distributed freshwater fish in the western United States. The southern California populations of R. osculus are identified as the Santa Ana speckled dace (SASD), though the SASD has not yet been formally recognized as a distinct taxon. Current mtDNA analysis performed in the Metcalf Lab has shown a reciprocally monophyletic relationship among three California regions; southern, central coast, and Owens Valley. Similarly, microsatellite genotyping has shown significant levels of geographic population structure. The purpose of this study was to provide nuclear DNA sequence data to determine the taxonomic status of the SASD to elucidate their evolutionary history and the relationships among the three regions, and to further define their evolutionary trajectory by comparing SASD sequence data to that of speckled dace from the Colorado River of Arizona. To examine this, three EPIC intron markers were sequenced on 54 samples representing all four regions. Based on the mtDNA and microsatellite data alone, there is strong support that the southern California populations of R. osculus are a reproductively isolated taxon at the species level. My study confirms this by showing the SASD to be reciprocally monophyletic for nuclear DNA markers, in conjunction with the mitochondrial DNA marker analyses. Because they are evolutionarily independent and face increased incidence of drought, fire, and flood, endangered species status should be considered.

Full textAbstract:
Understanding the impacts of hydrological drought is crucial to the conservation of freshwater fishes. In British Columbia, Nooksack dace (Cyprinidae: Rhinichthys cataractae) are an endangered riffle specialist and are threatened by extremely low summer flows. The purpose of this thesis was to explore the impacts of drought on Nooksack dace, whether pool habitats may act as refugia to mitigate these impacts, and to define minimum environmental flow requirements.
The first two objectives were addressed using a combination of field survey and experimental manipulations. A reduction in Nooksack dace population size with declining summer flow in Bertrand Creek, and a marked decrease in growth at low discharge in experimental riffles, indicated that low discharge has negative impacts on dace at both population and individual levels. Pool habitats were found to play a minor role in mitigating the negative impacts of hydrological drought (e.g., decreased growth rate), save as a refuge from stranding when riffles dewater.
The third objective was addressed using the Instream Flow Incremental Methodology (IFIM). Because this study involved an endangered species an emphasis was placed on evaluating two fundamental assumptions of the methodology. Experimental results for Nooksack dace growth at different depths and velocities provided support for the first assumption, that density-based Habitat Suitability Curves (HSCs) accurately reflect habitat quality, but only for the lower limits of the HSCs. Next, a significant positive relationship between Weighted Usable Area (WUA) and dace biomass was found, supporting the assumption that such a relationship exists. However, this relationship was weak indicating a high degree of uncertainty in how Nooksack dace biomass will respond at high discharges. The IFIM model predicted that habitat availability for Nooksack dace begins to decline most rapidly at discharges of 0.12 m³.s-¹. As there is low confidence in upper ranges of the HSCs this low flow threshold may underestimate declines with discharge, and therefore protection of at least 0.12 m³.s-¹ is considered necessary for the persistence of Nooksack dace individuals and populations. Compared to conventional instream flow criteria, 0.12 m³.s-¹ represents ~10% mean annual discharge which is the threshold for severely degraded habitat.

Full textAbstract:
“Liminal Spaces and The Disabled Body” explores Edmund Burke’s aesthetic paradigms as established in his An Enquiry into the Origin of Our Notions of the Sublime and the Beautiful to recover what disability meant for an eighteenth-century audience. I examine Burney’s Camilla and Eugenia’s disability as well as Dacre’s Zofloya and Victoria’s figurative hermaphroditism in terms of eighteenth-century views of deformity and physiognomy to argue that both Eugenia’s and Victoria’s deformities—Eugenia’s smallpox scars and injured leg and Victoria’s beautiful but too boldly delineated features—challenge the prevailing structures of aesthetics and expectations of feminine beauty. My thesis questions how eighteenth-century aesthetic theory constructs the modern concept of the “disabled” individual to argue that the female body with a disability or deformity surpasses the terms of submission and diminution instated by Burkean aesthetics. In turn, the disabled female gains purchase in literature due to her “liminal, between-categories status” as it strains masculine power structures and aesthetic and gender classification systems.

Pour obtenir des informations concernant les types des colorants et des liants de la couche picturale, ainsi que l’établissement de la composition quantitative et qualitative de différents mortiers ont été appliquées les méthodes analytiques suivantes : pétrographique et minéralogique, granulométrie, microsonde électronique et microscopie électronique à balayage (MEB), diffraction des rayons X, spectrométrie IR et spectrométrie IR Raman. Dans le Chapitre II a été faite une recherche sur les divers matériaux de la structure des peintures : matériaux de construction, mortier de liaison, couches d’enduit, pigments et liants. On a constaté que les peintres ont utilisé, au début de la période, des pigments chers et que l’on les a appliqués en état pur. Tels pigment ont été le cinabre et le bleu égyptien. D’autre part la palette s’est progressivement appauvrie. La riche gamme de pigments, existant pendant la période de la fin du IIIe au début du Ve, a devenu de plus en plus restreinte en aboutissant également à l’usage de l’ocre rouge qui a été rarement accompagné de couleur verte (terre verte) vers la fin du Ve et au VIe siècle ap. J.-C. Le Chapitre III présente les techniques de réalisation et le système de travail. On a déterminé que la technique principale d’exécution est a fresco, mais on a constaté aussi d’autres techniques (fresque à la chaux, peinture à la chaux, détrampe). Les constatations notées dans les chapitres précédents nous ont permis de faites la synthèse dans le Chapitre IV. Les matériaux et les techniques de réalisation de la peinture funéraire sont représentés en ordre chronologique. Dans le Chapitre V on a montré en détail 48 tombeaux de deux diocèses. Les décors des tombeaux ne sont pas figurés seulement au point de vue de matériaux et de techniques, on a aussi étudié leurs thèmes iconographiques et leurs motifs ornaméntaux. Le chapitre VI présente la conclusion principale de la thèse. Il évoque sous en résumé l’influence directe de l’art de l’Asie Mineure ainsi que l’influence indirecte de l’art des terres italiques. Le riche répertoire de thèmes est accompagné d’une large palette d’interprétations créatrices et de solutions techniques. Á la fin de la période, la peinture funéraire disparait. Ce fait nous incite à établir un lien avec le changement du rite funéraire. D’autre part, le matériau archéologique permet de constater un développement important de l’art figuratif pendant cette période. Ainsi la peinture murale rend-elle prioritaires d’autres structures architecturales, notamment les basiliques, les églises et les baptistaires chrétiens. Les abréviations présentent les publications périodiques et de diverses institutions. On a ajouté une liste des nomes antique des sites et leurs nomes modernes. La bibliographie représentent des sources et des textes antiques, des livre de base, ainsi que des publications sur la peinture antique grecque et romaine, recherche sur des monuments donnés, ainsi que telles présentant des problèmes déterminés sur les matériaux et la technologie de la peinture pariétale. Une liste des sites électroniques est également montréeThe research is presented in two volumes and a DVD record. Volume one represents the text part of the thesis consisting of introduction and 6 chapters with abbreviations, bibliography and indexes. The second volume includes 267 plates and 17 tables.In the introduction has been defined the chronological period of the review spanning through the years of the end of the ІІІd century until the fall of the late antique civilization on the Balkans in the end of the VІth and beginning of the VІІth century AC. A review of the study of the objects in Thracia and Dacia is presented in briefs.In chapter I examined the different analytical methods. The beginning part presents the research of the objects in situ. For the gathering of the information concerning the type of the pigments and adhesives used for realization of the murals, as well as for the differentiation of the qualitative and quantitative characteristics of the ingredient components of the different ground layers there have been used the following analytical methods: pictographic and mineralogical analyses, granulometry, electronic microprobes, CEM, structural Х-ray analysis, AEA-ICP, IR spectrometry and IR Raman spectrometry. The second chapter contains the examination of the different types of materials as: plasters, pigments and adhesives used for the realization of the tomb murals. The results are classified according to belonging to three basic groups – of natural origin, synthetic and mixed pigments. There has been proved that in the beginning of the period there had been used some most expensive pigments in an almost clear form as cinnabar and egyptian blue. However in time the palette gradually got poorer and by the end of the period it became limited to only dark red pigments (red ochre, rarely accompanied by green pigment (green earth). The results of the type of the adhesives used for the realization of the murals are presented in particulars. The use of non-organic adhesive - calcium hydroxide has been found. In Chapter ІІІ there are reviewed the picturesque technique and system of implementation. There has been defined the main technique a fresco, however the presence of other techniques has been also found. The constatations made in all previous chapters are summarized in Chapter ІV. In a chronological plan there were reviewed the materials and techniques which were in use. The Chapter V in details are presented all available tombs with painting murals, that were a subject of the present research. The murals have been outlined not only in the perspective of the implemented materials and techniques of realization, but also from the position of the analysis of the ornamental motives and iconographic system. The Chapter VI presents the main conclusion of the thesis. The direct influence of the art of Asia Minor is given in summarized form, as well as the indirect one – through the art of the land of Italy, for example. The rich repertoire of subjects is accompanied by a wealth of creative interpretations and technical solutions. The wall painting became a priority of the Church architecture at the end of Late Antiquity, which has also been proven by archaeological surveys. The palette of colours and technique of application used in tomb art found new implementation in depicting images of the already regulated Christian art in church architecture. The abbreviations contain periodical press publications and public institutions. There has been attached a list with the names of the archeological objects as known in ancient and contemporary time. The bibliography contains: the ancient authors, basic sources of information, specialized researches and publications on roman and late antique painting, publications on particular cultural monuments, as well as expert publications focused on specific problems of the materials and technology research
