Um componente considerado crítico para o manejo bem sucedido de populações silvestres é a manutenção da variação genética. No intuito de avaliar a magnitude e a distribuição da variabilidade genética existente em populações de Caiman latirostris, nove populações distribuídas ao longo do eixo latitudinal da distribuição da espécie no Brasil e uma população em cativeiro foram estudadas com auxílio de onze locos microssatélites. A diversidade gênica média (He=h) e a heterozigosidade média observada (Ho) apresentaram valores elevados, 0,628 e 0,567, respectivamente, denotando existência de elevada variabilidade genética para esta espécie nas regiões de estudo. A população paulista mesmo estando na zona intermediária de distribuição geográfica no Brasil não possui a maior variabilidade genética. O valor FST estimado foi 0,270 e o RST foi 0,342. Ambas as medidas de diferenciação entre as populações foram significativas (P<0,05). As altas estimativas de FST e RST sugerem a ausência ou fluxo gênico restrito entre essas populações, exceção feita entre as populações de Natal (RN) e João Pessoa (PB), onde não houve diferenciação significativa entre as populações, sugerindo assim que há fluxo gênico entre elas, fato confirmado pelo coeficiente de parentesco. Pôde-se concluir neste trabalho que a distância genética entre a população do litoral é afetada pela existência da Serra do Mar como barreira geográfica pelo fato desta população apresentar as maiores diferenciações genéticas e não se agrupar a nenhuma população pelo método de agrupamento UPGMA, mesmo estando próxima das populações paulista. A distância genética entre as populações parece não acompanhar a distância geográfica, em termos de gradiente latitudinal (r=0,206). Entretanto quando retiramos a população da Ilha do Cardoso esta correlação aumenta significativamente (r=0,540), indicando haver um certo padrão espacial da variabilidade genética entre as populações. O coeficiente médio de parentesco foi baixo entre e dentro das populações estudadas. Com estes resultados podemos começar a entender a dinâmica e estrutura social de populações de Caiman latirostris, e quanto mais se compreende sobre a biologia destes animais mais precisa serão decisões visando condições que permitam a existência continua da espécie. / A component considered critical for the managment well succeed of wild populations it is the maintenance of genetic variation. In the intention of evaluating the extend and the distribution of the existent genetic variability in populations of Caiman latirostris, nine populations distributed along the latitudinal axis of the distribution of the species in Brazil and a population in captivity they were studied with aid of eleven locos microsatellite. The genic mean diversity (He=h) and the observed mean heterozygosity (Ho) across all loci for all populations ranged from 0,628 and 0,567, respectively, denoting existence high genetic variability. The population from São Paulo being in the intermediate zone of geographical distribution in Brazil doesn't possess the largest genetic variability. The value dear FST was 0,270 and RST it was 0,342. Both differentiation measures among the populations were significant (P < 0,05). The higher estimates of FST and RST suggested a absence or low gene flow among those populations, exception done between the populations of Natal (RN) and João Pessoa (PB), where there was not significant differentiation among the populations, suggesting a gene flow pattern among them, fact confirmed by the related coefficient. It could be concluded in this work that the genetic distance among the population of the coast is affected by the existence of the Mountain of the Sea as geographical barrier for the fact of this population to present the largest genetic differentiations and not to group the any population for the grouping method UPGMA, same being close of the populations from São Paulo. The genetic distance among the populations seems not to accompany the geographical distance, in terms of latitudinal gradient (r=0,206). However when we removed the population of Cardoso's Island this correlation it increases significantly (r= 0,540), indicating there to be a certain space pattern of the genetic variability among the populations. The medium coefficient of related was low among and inside of the studied populations. With these results we can begin to understand the dynamics and it structures social of populations of Caiman latirostris.

The Chinese euphemisms have aroused much interest of many researches due to its distinctive function and diversity. The choice and use of Chinese euphemisms are affected by many factors such as the Chinese traditional culture, social customs, people’s self-cultivation, the situation context and linguistic context of a conversation, etc. Hence, the progress of society, the development of technology and the renewing of the concept make up the dynamic characteristic of the Chinese euphemisms. However, most studies focus mainly on the vocabulary people use and their expressing habits and patterns, there are few studies focus on how Chinese euphemisms develop along with the times. Studies that shed light on how modern people use broad euphemisms and narrow euphemisms are even less. Therefore, the purpose of this paper is to collect linguistic materials and design a questionnaire to make a survey on the current situation of using euphemisms by respondents of different age groups. The result of this survey shows that modern people are not only becoming less and less indirect in terms of the scope of using euphemisms, but also less and less tactful in terms of the vocabulary that they use. This phenomenon can be observed when people talk about topics such as death, disease, appearance, unemployment, marriage and privacy. Modern people tend to be relatively low decoratively worded. In other words, people are to some extent becoming less indirect and less tactful. This paper verifies the adaptability as well as the updating and upgrading of Chinese euphemisms. It also discusses the linguistic diversity of modern people in terms of using broad and narrow euphemisms under different contexts. This paper will not only help us to understand how Chinese language adapts to the change with the times, but also digs deeper into the great role that social culture plays in language development. / 汉语委婉语的功能鲜明、灵活多变，引起了很多研究的兴趣。汉语委婉语的选择和使用 受到中国的传统文化、社会风俗，人自身的修养内涵、情景和语境等多方面因素的影响，并伴 随着社会的发展、科技的进步、观念的转变而处于一个动态的变化过程。然而，目前的研究对 委婉语的词汇、表达方式及表达规律探讨的比较多，但是对汉语委婉语基于时代变化的研究则 较少，特别是对于在现代社会的日常交谈中，人们具体如何使用狭义和广义委婉语，以及探讨 他们在委婉语使用方面出现了哪些变化的研究则更少了。 因此，本论文旨在搜集语言素材并设计问卷，对不同年龄段的人委婉语的使用现状做一 个问卷调查。调查数据的结果表明，在现代社会的日常交谈中，不同年龄段的人使用汉语委婉 语的范围不仅缩小了，并且委婉程度也有一定的降低。具体体现为在死、病、相貌、 失业、 婚姻、隐私等话题下，人们现在倾向于使用修饰性较低，或者说委婉程度较低的委婉语。 本论文验证了委婉语的顺应性和更新替代性，并具体阐述了在现代社会的日常交谈中， 不同年龄段的人在不同语境下对广义和狭义委婉语选择的多样性。因此，本论文不仅有助于理 解汉语随时代变迁发展变化的趋势，也有助于更深入的理解社会文化在语言发展中发挥的巨大 作用。

This thesis examines the development of the soldier in late-Victorian Britain in light of the movement to rehabilitate the public image of the ordinary ranks initiated by the Cardwell-Childers Reforms. Venerated in popular culture, Tommy Atkins became a symbol of British imperial strength and heroism. Socially, however, attitudes to the rank-and-file were defined by a pragmatic realism purged of such sentiments, the likes of which would characterise the British public’s relationship with their army for over thirty years. Scholars of both imperial culture and the Victorian military have identified this dual persona of Tommy Atkins, however, a dedicated study into the true nature of the soldier’s position has yet to be undertaken. The following research will seek to redress this omission. The soldier is approached through the perspective of three key influences which defined his development. The first influence, the politics of the War Office, exposes a progressive series of schemes which, cultivated for over a decade, sought to redefine the soldier through the popularisation of military service and the professionalisation of the military’s public relations strategy and apparatus. A forgotten component of the Cardwell-Childers Reforms, the schemes have not before been scrutinised. Despite the ingenuity of the schemes devised, the social rehabilitation of the soldier failed, primarily, it will be argued, because the government refused to improve his pay. The public’s response to the Cardwell-Childers Reforms and the British perception of the ordinary soldier in the decades following their introduction form the second perspective. Through surveys of the local and London press and mainstream literature, it is demonstrated the soldier, in part as a result of the reforms, underwent a social transition, precipitated by his entering the public consciousness and encouraged by a resulting fascination in the military life. The final perspective presented in this thesis is from within the rank-and-file itself. Through the examination of specialist newspaper, diary and memoir material the direct experiences of the soldiers themselves are explored. Amid the extensive public and political discussion of their nature and status, the soldier also engaged in the debate. The perspective of the rank-and-file provides direct context for the established perspectives of the British public and the War Office, but also highlights how the soldier both supported and opposed the reforms and was acutely aware of the social status he possessed. This thesis will examine the public and political treatment of the soldier in the late-nineteenth century and question how far the conflicting ideas of soldier-hero and soldier-beggar were reconciled.

This diploma thesis dealt with the influence of relative weir height of rectangular broad-crested weir on discharge coefficient. Based on the level measurement in front of weir for different heights of the weir P and discharges were determined values of discharge coefficient according h/P. These values were compared with the results of measurements and relationships, which are mentioned in the professional literature. In conclusion were derived new relationships that can be used to calculate the discharge coefficient relative to the overflow head.

The thesis deals with possibilities of numerical modelling of an overflow over selected types of auxiliary spillways and then the possibilities are verified in particular localities. In thesis, there is carried out the determination of capacity of selected spillways by using several methods: the calculation of the overflow equation, one-dimensional and two-dimensional numerical models and physical model. The author created parametric analysis to each single method. Parametric analysis represent various hydraulic conditions. Subsequently, there is possible to express the effect of parametric analysis. The author makes a comparison of water levels received by mentioned methods set out under the specific hydraulic conditions by calibration of each model with the physical model. Finally, author recommends values of all coefficients which have an impact on results of numerical modelling of the flow over selected types of weirs mostly using like auxiliary spillways.

This study set out to establish an informed framework for the use of social network services in South African museums. Social network services are utilised by a wide demographic spectrum so they offer a cost-effective way to engage with communities and with existing and new stakeholders. The Standard of Generally Recognised Accounting Practice on Heritage Assets, or GRAP 103, and the draft National Policy on Digitisation of Heritage Resources imply that museum collections get documented and managed in digital form. It will coincidentally also enable museums to embrace the use of social network services and share the collections in their custody with many South Africans who are yet to experience the value of museums in the country. Museums are institutions in the service of society which acquires, conserves and communicates the tangible and intangible heritage of people and their environment. During the twentieth century museums have had to reinvent themselves from being unapproachable custodians of heritage to being part of society, willing to engage in discourses and be transformed to remain relevant to the communities they serve. The 2011 Census has found that about 18.2 million of 51.7 million South Africans have had access to the Internet before. Active Internet users however, are about half that figure because it is expensive, the broadband and telecommunications network is not efficient or because people have not yet experienced the value it offers. Government regulations compel Information and Communication Technology (ICT) enterprises to spend 1.5% net profit after tax on socio economic development initiatives. This presents an opportunity for museums as educational institutions to engage with such enterprises to expand Internet access and engage with local communities. The social network service field offers various ways to communicate collections and engage with communities through text, photographs, video and location-based technologies. Various notable local and international initiatives were discussed in this study. For example the Kulturpool which allows visitors to create cyber collections from digitised museum objects and contribute to the knowledge of such objects by allowing them to submit and share information for others to read. SAHRIS, the digital database offered by the South African Heritage Resources Agency, holds the key to similar ventures that museums could pursue. The regulative framework involves privacy, copyright and ethical issues which museums should abide by. Because of the pervasiveness of ICTs museums should take note of these regulations even if they decide not to pursue social network initiatives. ICT skills in museums are insufficient and should be improved upon. Social network services offer training and guidelines on how to use them, which could be a great help provided the reader has a good command of the English language. Cognisance must be taken of an overview social network services and their uses, and of the ethical and regulative framework for museums to benefit from using social network services to engage with communities. This way, communities may benefit from having access to the museum online. / Dissertation (MHCS)--University of Pretoria, 2014. / gm2014 / Historical and Heritage Studies / unrestricted

La diversité bêta est une mesure essentielle pour décrire l'organisation de la biodiversité dans l'espace. Le calcul des contributions locales à la diversité bêta (LCBD), en particulier, permet d'identifier des sites à forte unicité écologique montrant une diversité exceptionnelle au sein d'une région d'intérêt. Jusqu’à présent, l'utilisation des LCBD s'est restreinte à des échelles locales ou régionales avec un petit nombre de sites. Dans ce mémoire, j'ai examiné si les modèles de répartition d'espèces (SDM) permettent d'évaluer l'unicité écologique sur de plus grandes étendues spatiales. J'ai également étudié l’effet des changements d’échelle sur la quantification de la diversité bêta. Pour ce faire, j'ai utilisé la base de données eBird et des arbres de régression additifs bayésiens pour prédire la répartition des parulines en Amérique du Nord. J'ai ensuite calculé les LCBD sur ces prédictions, ce qui permet de couvrir de plus grandes étendues spatiales et un nombre de sites plus élevé. Mes résultats ont montré que les SDM fournissent des estimations d'unicité fortement corrélées avec les données observées et montrant une association spatiale statistiquement significative. Ils ont également montré que la relation entre la richesse et les LCBD varie selon la région et l'étendue spatiale et qu'elle est influencée par la proportion d'espèces rares dans les communautés. Ainsi, les sites identifiés comme uniques peuvent varier selon les caractéristiques de la région étudiée. Ces résultats montrent que les SDM peuvent être utilisés pour prédire l'unicité écologique, ce qui pourrait permettre d'identifier d'importantes cibles de conservation au sein de régions non échantillonnées. / Beta diversity is an essential measure to describe the organization of biodiversity through space. The calculation of local contributions to beta diversity (LCBD), specifically, allows the identification of sites with high ecological uniqueness and exceptional diversity within a region of interest. To this day, LCBD indices have primarily been used on regional and smaller scales, with relatively few sites. Furthermore, their use is typically restricted to strictly sampled sites with known species composition, leading to gaps in spatial coverage on broad extents. Here, I examined whether species distribution models (SDMs) can be used to assess ecological uniqueness over broader spatial extents and investigated the effect of scale changes on beta diversity quantification. To this aim, I used observations recorded in the eBird database and Bayesian additive regression trees to model warbler species composition in North America, then computed LCBD indices on the predictions, thus covering a broader spatial extent and a higher number of sites. My results showed that SDMs provide uniqueness estimates highly correlated with observed data with a statistically significant spatial association. They also showed that the relationship between richness and LCBD values varies according to the region and the spatial extent and that it is affected by the proportion of rare species in communities. Sites identified as unique may therefore vary according to regional characteristics. These results show that SDMs can be used to predict ecological uniqueness over broad spatial extents, which could help identify beta diversity hotspots and important targets for conservation purposes in unsampled locations.

Weirs belong to the basic water structures mainly creating vertical contraction of stream against the flumes, which creating mainly horizontal contraction of stream. In the case of the flow over weir usually occurs change from subcritical flow over critical with critical depth to supercritical flow, therefore overflow. Weirs with rectangular control section are described rectangular longitudinal and transverse profile and horizontal crest. Can be distinguish three basic inflow directions to weir. The first is frontal inflow, which is the most frequent in practice. The second is lateral inflow used in distribution and consumption objects. The third is lower inflow used as laboratory weirs, weirs with deeply submerged wall, etc. In terms of knowledge of influence listed directions of inflows, currently are not sufficiently researched the cases of frontal inflow with side contraction and lower inflow on all types of weirs. Due to extent of the issue, labour is focused only on frontal inflow over broad-crested weir with side contraction and lower inflow over broad-crested weir without side contraction. The goal of the labour was to summarize the current knowledge of the flow over broad-crested weir with side contraction and lower inflow over broad-crested weir without side contraction, describe the character of the flow at the overflow and on the basis of it determine recommendations for measurement and calculation of discharge. Further to define unexplored area, specify methods of solution and verify own measurements. The research dealt with application and optimal numerical model setting for to solve the problem.
