Full textAbstract:
A história dos Censos no Brasil mostra que a preocupação com a componente territorial em levantamentos estatísticos, surgiu no recenseamento de 1940, quando, pela primeira vez, o IBGE procurou retratar aspectos da realidade geográfica, de interesse para a operação de coleta, em bases cartográficas, uma tarefa complexa devido à grande extensão do território brasileiro e principalmente no que se refere à qualidade do material cartográfico disponível à época. Atualmente crescem as demandas em nosso país, por informações cada vez mais detalhadas e geograficamente posicionadas. Governadores e prefeitos, órgãos de planejamento municipais e estaduais, investidos de maior autonomia e de novas responsabilidades após a Constituição de 1988, dependem hoje como nunca dos censos para definirem suas políticas públicas, com base em informações atualizadas sobre a população sob suas jurisdições. Entretanto, as demandas por informações agregadas à posição também vêm de outras esferas, que vão do setor não-governamental e privado ao governo federal, fazendo com que muito aumentasse a relevância dos censos e por conseqüência os resultados das pesquisas. Para atender a grande demanda, o IBGE vem continuamente aperfeiçoando o que denominamos de Base Territorial, que é um sistema integrado de informações de natureza geográfica e alfanumérica e se constitui no principal requisito para a garantia da adequada cobertura das operações de levantamento censitário. Face a este novo cenário, o IBGE iniciou a elaboração de mapas da base territorial em meio digital, durante as ações preparatórias para o Censo 2000, se deparando com as dificuldades de integração das áreas urbanas e rurais e a baixa qualidade dos insumos de mapeamento em escala cadastral, disponível nas áreas menos desenvolvidas, pois a Instituição não é produtora de mapeamento em escala cadastral. A metodologia proposta visa melhorar a qualidade dos Mapas de Setores Urbanos MSU, com a utilização de imagens Google Earth, a partir software MicroStation 95, periféricos e aplicativos de conversão disponíveis no IBGE, com o estabelecimento de uma nova rotina de trabalho para produção e substituição dos mapas de setores urbanos, de forma a garantir uma maior representatividade territorial dos dados estatísticos para divulgação.<br>The history of census in Brazil shows that the worry with the territorial component in statistical surveys appeared in the 1940 Census. For the first time the Brazilian Institute for Geography and Statistics (IBGE) tried to describe aspects of the geographic reality, of interest for the assembling operation in cartographic basis a complex task due to the great extension of the Brazilian territory and mainly in relation to the quality of the cartographic material available at that time. Nowadays in our country the demands for more detailed and geographically positioned data grow governors and majors, planning institutes at municipal and state levels, owners of more autonomy and new responsibilities after the 1988 Constitution depend today as never before on the census to define their public policies based on up-dated data on the population under their jurisdictions.Nevertheless the demands for date linked to the position come also from other areas which range from the non-governmental and private sector of the Federal Government increasing the importance of census and by consequence the results of the researches. To respond to the great demand, the IBGE continuously implement the so-called Territorial Base, which is an integrated data system of geographical nature and alfa-numerical and it is the main requisite for the warrant of the adequate cover of the census operations. Due to this new scenery, IBGE started the elaboration of maps of the territorial base through digital means during the preparation actions for the 2000 Census, facing difficulties concerning the integration of urban and rural areas and the low quality of mapping data in cadastral scale, available in less developed areas once the institution does not produce in a cadastral scale.The methodology proposed aims at improving the quality of Urban Sectors Maps MSU, using the Google Earth images, from the software Micro Station 95, peripheric and applicative of conversion available at IBGE, with the establishment of a new routine of work for the production and replacement of the maps of the urban sectors, in order to guarantee a greater territorial representativeness of statistical data for dissemination.

Full textAbstract:
This dissertation is a case study of an agency attempting to continue to operate in terms of an outmoded paradigm, one whose foundation is based on a reference point for decision and action that does not fit the social, political and organizational conditions of postmodernity. The orientation of the study is toward public administration as political process; a political process which reflects the postmodern condition. Postmodern tendencies in culture and society are characterized by a particularly salient "thinning" of reality or development of hyper-reality where communication has lost the check on authenticity found in dialogue. This thinning of the macro culture exists in dialectical contradiction to more robust communities of discourse developing in enclaves in a tendency referred to as neotribalism. These dialectical tendencies lead to "simulated politics," where political entrepreneurs traffic in symbols rather than deeds and substantive policy making is restrained. This development favors those who benefit from the status quo.
The Census Bureau is the focal agency. It is facing a crisis of legitimacy in its standoff with the Republican-controlled Congress over its plan to use sampling and estimation to produce a statistically adjusted apportionment count for Census 2000. The case of the Census 2000 stand-off between technocrats at the Census Bureau, supported by the Democratic Clinton administration and organizations and governmental entities that are adversely affected by census undercounts, and the Republican-dominated Congress, is an example of non-dialogic communication. It is masked by a trafficking in symbols and potentially will most likely lead to maintenance of the status quo in the form of traditional census methodology. This methodology differentially undercounts African Americans, Hispanics, American Indians and Asians, as compared to whites. Republicans compare the Census 2000 plan to use sampling to adjust the census for undercounts to the "Hillary Health Care Model" (a derogatory reference to the First Lady's involvement in public policy), describing it as a "polling technique," while Democrats and statisticians cast the argument of Republicans as one of "politicians trying to preserve their domain," and of playing "racial politics". The strategy of the Republican Congress appears to be to discredit the expertise of the Census Bureau and to rely on the legal process and a conservative Supreme Court to derail and nullify the plan for Census 2000, thus causing the agency to revert to the "status quo." Curiously, the Census Bureau has set itself up for this potential outcome by taking a strategically counterproductive and disastrously adversarial approach to the Congress. The Census Bureau has fundamentally misperceived the contemporary cultural environment and the politics that goes with it. It no longer can represent its own position as nonpolitical, value-free science, representing truth and moral right. This lack of perspective has critically hampered the agency's ability to negotiate in a political discourse appropriate to postmodernity.
The goal of the study is to make a contribution to furthering organization-environment theory, with emphasis on the political environment. It is this aspect of organization theory generally that has most relevance to Public Administration but that has been least well developed. The dissertation is designed to conform to the traditional Inter-University Case Program (ICP) case study format. As such, the study addresses the broad issue of agency-environment relationship and the role of the public administrator within that environment. As with all ICP-type studies the research does not lead to an "answer." This is especially appropriate now because in the postmodern condition there is no one answer or truth to be found by rational analysis. Rather, ideas, insights, and various conclusions are offered.<br>Ph. D.

Lafferty, Hugh H. "Analysing quizzes using a census." Thesis, Sheffield Hallam University, 2014. http://shura.shu.ac.uk/19935/.
Full textAbstract:
This is a theoretical study of the marks that could be obtained from quizzes, when a census is done. The quizzes are limited to 'special' quizzes and we look at how many obtain a particular mark, and what happens to the distribution of marks when the guessing problem is tackled. Without building any tools we can do some calculations, but then we are driven to writing computer programs that calculate and display the distribution of marks. When computer programs are written they involve such large numbers that computer programs cannot normally handle them. Thus we are driven to languages, like C, where integers of an arbitrary size can be handled in libraries like LEDA. Quizzes can either have all their stems answered or have some of their stems missed. The philosophy of this study is to start off simply and gradually get more complicated, and so 'special' quizzes where all stems are answered are looked at first followed by 'special' quizzes where stems can be missed. The guessing problem is tackled, in this study, by: a) using negative marking, b) raising the pass mark, c) using a more complex quiz. What we find is that when the guessing problem of 'special' quizzes is exactly tackled the distribution of marks moves to the left (when the mean mark is 0), and that the tackling of the guessing problem leads to more problems. All 'special' stems include the answer, which can be guessed. The likelihood of guessing the correct answer to a stem decreases as the complexity of the quiz increases, but then the likelihood of passing also decreases. As the complexity of the quiz increases the distribution is 'bunched' at the lower end which means that half the marks of distribution are between the lowest mark and the mark where the mean occurs. The main conclusion is not quantitative but qualitative and is "Do not use 'special' quizzes for measuring understanding" because 'special' quizzes do not provide a space that allows one to demonstrate one's understanding and are therefore in-valid when understanding is claimed to be measured.

Previous issue date: 2015-02-26<br>O censo é uma operação estatística complexa que um país executa de dez em
dez anos e exerce um papel fundamental na obtenção de dados sobre a
população. Os dados obtidos pelo censo são usados para o planejamento do
país e em diversas áreas de pesquisa. Para que os dados sejam fiáveis é
necessário que no âmbito da concepção do projeto se defina as estratégias de
execução desde a fase pré-censo, censo e pós-censo. A fase pós-censo, que é o
foco desta pesquisa, caracteriza-se pelo tratamento dos dados coletados no
campo durante o censo e disseminação dos resultados em forma de tabelas,
gráficos, mapas, dentre outros. Para esta pesquisa, foram selecionados 11
indicadores que fazem parte dos dez temas publicados por províncias em forma
de quadros nas disseminações definitivas do censo 2007. Os indicadores foram
modelados, foi criada uma base de dados espaciais e representados através de
mapas em 11 províncias que compõem Moçambique. A modelagem consistiu
na elaboração do modelo conceitual em ArgoUML, um software livre e de
código aberto. Devido a restrições impostas pelo ArgoUML foi utilizado o
DBDesigner Fork, software livre de código aberto, que permitiu a geração do
modelo entidade-relacionamento e de Script SQL. Por meio do comando SQL no
pgAdmim III foi possível executar o Script SQL e implementar a base de dados do
censo em forma de tabelas. Após a implementação foi possível observar toda a
modelagem elaborada. A representação espacial dos indicadores também foi
feita a partir de software livre de código aberto - Quantum GIS. A partir dos
mapas elaborados foi feita a análise dos indicadores por província e observou-se
que as províncias do centro e norte de Moçambique apresentam baixos
resultados em relação às províncias localizadas no sul.<br>The census is a complex statistical operation that a country runs every ten years
and plays a key role in obtaining data on the population. The data obtained by
the Census in a country are used for planning and also in several areas of
research. For data to be reliable it is necessary that, within the project design to
define implementation strategies starting from pre-census phase, census and postcensus.
The post-census phase, which is the focus of this research is characterized
by the processing of data collected in the field during the census and
disseminating the results in tables, graphs, maps, and other formats. For this
research, we selected eleven indicators that are part of the ten subjects published
per provinces in tabular format within the final disseminations in the 2007 census.
The indicators were modeled, a spatial database was created and represented
through maps in eleven provinces that comprise Mozambique. The modeling was
to draw up the conceptual model in ArgoUML a free and open source software.
Due to restrictions imposed by ArgoUML, the DBDesigner Fork was used, a free
open source software, which allowed the generation of the entity-relationship
model and the SQL script. Through SQL command in pgAdmim III was possible to
run the SQL script and implement the census database in a table format. After
implementation was possible to observe all the modeling done. The spatial
representation of the indicators was also done through the free open source
software - Quantum GIS. From the maps drawn up, an analysis of the indicators
per province has been made and it was observed that the provinces of central
and northern Mozambique have low results comparing to the provinces located in
the south.

Full textAbstract:
Historical census data provide a snapshot of the era when our ancestors lived. Such data contain valuable information for the reconstruction of households and the tracking of family changes across time, which can be used for a variety of social science research projects. As valuable as they are, these data provide only snapshots of the main characteristics of the stock of a population. To capture household changes requires that we link person by person and household by household from one census to the next over a series of censuses. Once linked together, the census data are greatly enhanced in value. Development of an automatic or semi-automatic linking procedure will significantly relieve social scientists from the tedious task of manually linking individuals, families, and households, and can lead to an improvement of their productivity. In this thesis, a systematic solution is proposed for linking historical census data that integrates data cleaning and standardisation, as well as record and household linkage over consecutive censuses. This solution consists of several data pre-processing, machine learning, and data mining methods that address different aspects of the historical census data linkage problem. A common property of these methods is that they all adopt a strategy to consider a household as an entity, and use the whole of household information to improve the effectiveness of data cleaning and the accuracy of record and household linkage. We first proposal an approach for automatic cleaning and linking using domain knowledge. The core idea is to use household information in both the cleaning and linking steps, so that records that contain errors and variations can be cleaned and standardised and the number of wrongly linked records can be reduced. Second, we introduce a group linking method into household linkage, which enables tracking of the majority of members in a household over a period of time. The proposed method is based on the outcome of the record linkage step using either a similarity based method or a machine learning approach. A group linking method is then applied, aiming to reduce ambiguity of multiple household linkages. Third, we introduce a graph-based method to link households, which takes the structural relationship between household members into consideration. Based on the results of linking individual records, our method builds a graph for each household, so that the matches of household's in different census are determined by both attribute relationship and record similarities. This allows household similarities be more accurately calculated. Finally, we describe an instance classification method based on a multiple instance learning method. This allows an integrated solution to link both households and individual records at the same time. Our method treats group links as bags and individual record links as instances. We extend multiple instance learning from bag to instance classification in order to allow the reconstruction of bags from candidate instances. The classified bag and instance samples lead to a significant reduction in multiple group links, thereby improving the overall quality of linked data.

Full textAbstract:
There is now convincing evidence from imaging and polarization studies that the appearance of Active Galactic Nuclei (AGN) depends strongly on orientation. This thesis proposes to address this question by imaging a sample of low-redshift radio-selected galaxies in the infrared, where the obscuration due to dust is reduced, in the hope of providing an unbiased survey of the line-of-sight extinctions towards AGN and the relative numbers of hidden sources. The low redshift of the sample allows the study of similar luminosity Fanaroff-Riley class I and class II sources, with the opportunity to explore the nuclear luminosity function of lower luminosity objects than in previous studies. Infrared K and L' images were obtained for 28 galaxies. The non-thermal nuclear contribution to the K band flux is then estimated by subtracting a fitted two-dimensional surface brightness galaxy model from each image. The stellar contribution to the L' flux is estimated by fitting simple stellar population models to the optical spectra of a subsample of the objects and calculating the infrared K-L' colour of these fitted populations. Optical spectra were obtained for 13 objects in the sample. The reddening towards the nucleus is calculated by subtracting the intrinsic K-L' colour of a quasar or starburst from the observed value. Nuclear sources are detected in 10 members of the sample. The intrinsic luminosities of all these sources would put them above the quasar/Seyfert dividing line of Mv < -23, making them possible candidates for obscured radio-loud quasars. The correlation between extinction and orientation is then explored. The expected anti-correlation between core-to-lobe ratio R and extinction is not apparent, whilst a possible correlation between extinction and galaxy size is observed, larger galaxies appearing to contain more dust.

Full textAbstract:
The purpose of this research is to collect in a distinct corpus all the Latin verse inscriptions found in Roman Britain, those entirely metrical and those mixed with prose, those definitely metrical and those questionably so as well, analyse them both individually and as a block, with all the relative interconnections. The texts are also considered as evidence for a certain type of Romanisation spread in the province from the first to the fourth century AD. The aim of my research is to: - create a complete census of all the Latin verse inscriptions gathered from Roman Britain - trace the history of their discovery and map out the previous, including antiquarian, studies on them. This proves to be particularly useful for those inscriptions that experienced a tangled history and where with time some crucial details about the text and its archaeological context went missing in the accounts. - analyse the texts both from an epigraphic-historical and linguistic-philological point of view - offer fresh interpretations and supplements of the fragmentary texts - put the inscriptions in relation to their archaeological context - consider the implications for the cultural level of the province during the Roman occupation The results arc compared to those extrapolated from the metrical inscriptions found in Gallia Belgica. My investigation has clearly shown that the use of verse inscriptions in Britannia was markedly different from that in neighbouring Belgica. The comparison brings interesting conclusions and observations regarding the different approach and use of verse inscriptions in the two Roman provinces. Latin verse inscriptions represent an interesting key-study on the leve I of culture and sophistication that the Romans, together with the locals, achieved in a provincial environment. The comparative study proves the thesis that verse inscriptions do say something about the type of Romanisation of a province: the metrical texts found in Belgica are in fact quite different from those from Britannia.

Full textAbstract:
Inequality is a social phenomenon that exists across all nations; it is a condition which means that not everyone enjoys the same access to resources of all kinds and to certain positions that society values. Despite its importance, in Peru, the analysis of different approaches to inequality was not taken up until the 20th century, since it was only then that data began to be prepared to enable its study. Because detailed analyses of inequality did not exist before the 20th century, the objective of this study is to estimate income inequality in Peru at the end of the 19th century on the basis of the 1876 census, the first population and housing census of the Republican era. This census is considered to be particularly important for its utilization of modern techniques to enumerate the inhabitants of the day.<br>La desigualdad es un fenómeno social que existe en todas las naciones, es una condición que implica que las personas no gocen del mismo acceso a los recursos de todo tipo y a ciertas posiciones que valora la sociedad. A pesar de la importancia, en el Perú, estimaciones sobre diferentes enfoques de la desigualdad fueron abordados a partir del siglo XX debido a que desde aquella época recién se elaboran datos que hicieron posible su estudio. Dado que no existen estimaciones detalladas sobre la desigualdad antes del siglo XX, el objetivo de este estudio es estimar la desigualdad de ingresos en el Perú a finales del siglo XIX tomando como base al censo de 1876, primer censo de población y vivienda de la Época Republicana. Se le considera el más importante por ser el que contó con técnicas modernas para el empadronamiento de los habitantes de aquella época.

Full textAbstract:
Increasing food insecurity, lack of sustainable food systems, and a desire to participate in the food system are prompting the growth of various forms of urban agriculture: community gardens, urban homesteads, and urban farms. Urban farms, as distinct from other urban agriculture projects, are defined by the sale of their product. They raise produce and grow ornamentals to sell in neighbourhoods, all while building urban food networks that connect communities to their food.
Resilient localized food production systems must be economically, socially, and environmentally sustainable to succeed in a changing environment. Research on urban agriculture has largely focused on community gardens and their social benefits, leaving little known about entrepreneurial urban farms. This study examines the business models and economics of Metro Vancouver’s urban farms through a newly developed tool, the ‘Urban Farming Census.’ The use of this semi-structured interview tool revealed revenues, costs, financing, and sales models of urban farmers as well as their community connections and benefits. The Urban Farming Census was applied during the 2010 and 2011 growing seasons, capturing the first attempts by Vancouver’s urban farming organizations growing sustainable businesses.
In 2010, eight urban farms produced $128,000 worth of produce on 2.31 acres, supporting 17 paid employees. In 2011, ten urban farms sold $170,000 worth of produce on 4.19 acres, supporting 30 paid employees. Urban farms do more than sell produce; they educate their communities about food production and provide space for individuals and communities to explore their intergenerational, multicultural food cultures.

The thesis describes the creation of the classification: selection of the variables, assembly of the classification database, the methods of standardisation and the clustering procedures, together with some discussion of alternative methodologies that were considered for use. The processes used for creating the clusters, their naming and description are outlined. The classification is mapped and visualised in a number of different ways. In order to enable a classification of OAs to be possible the document starts with a review of the history of area classification and issues surrounding its future development. The methodological and theoretical issues in the creation of a classification system are also discussed. In order to test out the practicalitie s of creating a classification system, a classification of UK local authorities was created prior to the construction of the OA classification. The thesis describes the quality assurance procedures that the OA classification was put through. This included an innovative consultation exercise. This ensured that the classification was of enough quality and without error, enabling it to be published as a ‘National Statistic’. Examples of use of the classification are presented, outlining the value and relevance of the classification to social research. The OA classification is connected to other scales of classification to form a multi-scale classification system enabling the socio-demographic pattern of the UK to be examined at multiple scales. The project had to overcome numerous methodological issues due to the size of dataset that was used. The project used a new methodology to create the first free-to-use small scale classification of the UK. The classification was published as a ‘National Statistic’ on the 29th July 2005 and is freely available . The classification can be downloaded from the ONS website at http://www.statistics.gov.uk/about/methodology_by_theme/area_classification/oa/default.asp or via the School of Geography, University of Leeds website at: http://www.geog.leeds.ac.uk/people/d.vickers/OAclassinfo.html. Alternatively it can be ordered on CD by contacting info@statistics.gov.uk. The publication of the classification as a ‘National Statistic’ has created a resource that can be used by private, public and academic researchers.

Full textAbstract:
Le recensement provincial est une institution centrale de l’Empire romain. Né avec le Principat, il était destiné à estimer les ressources humaines et matérielles des territoires sous domination romaine, et s’est imposé comme la clé de voûte de la fiscalité provinciale. Néanmoins, il demeure mal connu. Cette situation vient de la faiblesse numérique des sources et de leur nature. En dehors de l'Égypte, les cens provinciaux sont essentiellement connus grâce à des inscriptions dédiées aux sénateurs et chevaliers ayant participé à ces opérations. Pour étudier le recensement à l'échelle de l'empire, il nous donc a paru nécessaire de diversifier les points de vue et de ne pas nous limiter à l'approche la plus fréquemment adoptée dans les études consacrées au census, l'analyse prosopographique. Bien que cette dernière s'impose comme la plus naturelle étant donné la nature de la documentation qui nous est parvenue, elle limite le champ d'étude aux seules provinces dans lesquelles sont attestés des censiteurs impériaux et peine à rendre compte de la logique d'ensemble de l'institution comme des modalités selon lesquelles l'information était collectée. Notre objectif était d'écrire une histoire fiscale et politique du recensement, mais aussi une histoire de ses procédures et non pas seulement de ses agents. Nous avons donc choisi d’élargir l’angle d’approche et d'inclure dans notre corpus toutes les sources littéraires, papyrologiques et juridiques susceptibles de nous éclairer sur cette institution. La première partie est consacrée aux aspects fiscaux et tente de comprendre le fonctionnement de l’impôt provincial. Dans quelles mesures le recensement se prêtait-il à la collecte des informations nécessaires à la levée des tributa ? La deuxième s'intéresse au déroulement des opérations dans les diverses provinces. Notre objectif est d'identifier les différents niveaux de collecte de l'information tout en rendant compte des différences régionales dont témoignent les sources. Au coeur de cette partie se trouve une réflexion sur la complémentarité entre le niveau local et le niveau provincial et sur les documents qui étaient produits aux divers échelons. Enfin, nous abordons dans un troisième temps les aspects institutionnels et politiques afin de comprendre dans quelles mesures cette institution était caractéristique du nouveau régime qui vit le jour avec Auguste. Cette partie est également consacrée à l'étude des relations entre les agents en charge des opérations et les provinciaux qui y étaient soumis<br>The provincial census is a key institution of the Roman Empire. Instituted by the first Princeps, Augustus, it was aimed at estimating the human and material resources of the territories which were under Roman control, and thus proved to be a cornerstone of the Roman fiscal system. Nevertheless, it remains mostly unknown to this date, which can be explained by the lack of sources and by their nature: apart from Egypt, provincial censuses are mostly attested through inscriptions dedicated to senators and knights who took part in these operations. In this dissertation, we chose to tackle the subject from novel perspectives and not to limit ourselves to the prosopographic approach that remains so far the most frequently adopted one. Despite its relevance given the nature of the sources, it restricts the study to the provinces in which census officials are known, and fails to give a comprehensive idea of the institution and of the methods through which information was collected. Our goal was not only to write a fiscal and political history of the census, but also to describe its process and identify its agents. To this end were included into our corpus all the literary, papyrological and juridical sources that might improve our understanding of this institution. Firstly, we focused on the two main provincial taxes, i.e. tributum soli and tributum capitis, in order to describe the fiscal system at work in the provinces and to identify the criteria on which these tributa were imposed. Secondly, we studied the way information was collected during the census. Our goal was to unravel the levels (local, provincial) through which data transited, their interactions, and the documents each one of them produced. At the same time, we wanted to emphasize the differences that existed between provinces, and to explain them. Finally, we addressed the institutional and political aspects of the provincial census: to what extent was this institution representative of the new regime that appeared with Augustus, and an opportunity for the provincials to initiate a dialog with the Princeps through his representatives?

Full textAbstract:
This thesis assesses approaches to population surface modeling by pulling together the benefits of reference gridded population data with local regression procedures and geographically weighted regression. This study provides a more detailed assessment of surface modelling accuracy than was achieved in any previous studies to assess factors which explain errors in the predictions. The primary aim of this thesis is to evaluate Martin’s (1989) population surface modeling approach and also design and implement a method using secondary data, suitable for application in England and Wales. This research is based on the idea that population data presented for a single zone could be redistributed in the zone using local parameters such as housing density. A weighted sum performs the spatial redistribution. The thesis also aims to make use of remote sensing (RS) data and image processing techniques such as maximum likelihood classification and normalised difference vegetation index to identify (un) populated cells. The potential of Landsat images and RS data analysis is assessed particularly for countries where high quality land use data are not readily obtainable, and their generation is not feasible in the near future. This thesis focuses on the identification of unpopulated cells, rather than populated units, using RS data. Case studies make use of data from Northern Ireland (NI), and Jonkoping in southern Sweden. The outcomes indicate the impact of population density, population variance, and resolution of source zones on the accuracy of population allocation to grid cells using Martin’s (1989) model. The results show significant accuracy in prediction to 100m cells using an alternative approach based on settlement data for NI and this is recommended as an alternative method for England and Wales. It also concluded that there the potential to generate population surfaces using Landsat data for areas where local residential data are not easily accessible.

Full textAbstract:
Stereo vision is a very useful, yet challenging technology for a wide variety of applications. One of the greatest challenges is meeting the computational demands of stereo vision applications that require real-time performance. The FPGA (Field Programmable Gate Array) is a readily-available technology that allows many stereo vision methods to be implemented while meeting the strict real-time performance requirements of some applications. Some of the best results have been obtained using non-parametric stereo correlation methods, such as the rank and census transform. Yet relatively little work has been done to study these methods or to propose new algorithms based on the same principles for improved stereo correlation accuracy or reduced resource requirements. This dissertation describes the sparse census and sparse rank transforms, which significantly reduce the cost of implementation while maintaining and in some case improving correlation accuracy. This dissertation also proposes the generalized census and generalized rank transforms, which opens up a new class of stereo vision transforms and allows the stereo system to be even more optimized, often reducing the hardware resource requirements. The proposed stereo methods are analyzed, providing both quantitative and qualitative results for comparison to existing algorithms. These results show that the computational complexity of local stereo methods can be significantly reduced while maintaining very good correlation accuracy. A hardware architecture for the implementation of the proposed algorithms is also described and the actual resource requirements for the algorithms are presented. These results confirm that dramatic reductions in hardware resource requirements can be achieved while maintaining high stereo correlation accuracy. This work proposes the multi-bit census, which provides improved pixel discrimination as compared to the census, and leads to improved correlation accuracy with some stereo configurations. A rotation-invariant census transform is also proposed and can be used in applications where image rotation is possible.

Full textAbstract:
In 2011, Statistics Austria carried out its first register-based census. Advantages of using administrative data for statistical purposes are, among others, a reduced burden for respondents and lower cost for the National Statistical Institutes (NSI). However, new challenges, like need for a new approach to the quality assessment of this kind of data arise. Therefore, Statistics Austria developed a comprehensive standardized framework to evaluate data quality for register-based statistics. In this paper, we present the basic concept of this quality framework and provide detailed results from the quality evaluation of the Austrian census of 2011. More specifically, we derive a quality measure for each census attribute from four complementary hyperdimensions. The first three of these hyperdimensions address the documentation of data, the usability of records and an external data validation. The fourth hyperdimension focuses on the quality of data imputations. The proposed framework combines these different quality-related information sources for each attribute to form an overall quality indicator. This procedure allows to track changes in quality during data processing and to compare the quality of different census generations.

Full textAbstract:
Comprendre comment se forment les étoiles est l’une des questions fondamentales auxquelles l’astronomie entend répondre. Malheureusement, nous ne pouvons pas étudier la formation stellaire en temps réel et différentes méthodes indirectes doivent être utilisées pour faire la lumière sur ce sujet. L’objectif principal de cette thèse est de déterminer la fonction de masse initiale, la distribution de masse des étoiles à leur naissance, dans différentes associations et régions de formation d’étoiles. La fonction de masse est le produit direct de la formation stellaire et constitue donc un paramètre d’observation fondamental pour contraindre les théories de formation stellaire et sous-estellaire. Nous nous sommes concentrés sur l’amas ouvert de 30 Ma IC 4665 et la région de formation d’étoiles de 1 - 10 Ma de Upper Scorpius (USC) et r Ophiuchi (r Oph). Nous avons combiné l’astrométrie et la photométrie de Gaia Data Release 2 avec nos observations au sol pour préparer un catalogue profond et étendu de chaque région. Ensuite, nous avons calculé les probabilités d’appartenance en utilisanttoute l’astrométrie et la photométrie disponibles et identifié les membres à haute probabilité. Nous avons utilisé la liste finale des membres pour estimer la distribution de magnitude, et les fonctions de luminosité et masse de ces associations. Alors que la première a l’avantage d’être indépendante des modèles d’évolution, tandis que les fonctions de luminosité et de masse peuvent être utilisées pour contraindre les mécanismes de formation d’étoiles. L’étude d’IC 4556 nous a permis d’identifier des objets sous-stellaires, sans pour autant pouvoir fournir un recensement complet dans ce domaine de masse. Dans USC et r Oph, nous avons identifié une population très riche d’objets sous-stellaires, significativement plus nombreux que les prédictions des modèles de formation par effondrement de coeurs moléculaires, suggérant que la formation de naines brunes et d’objets de masses planétaires isolés par des phénomènes d’éjection dans des systèmes planétaires a une contribution importante et du même ordre que l’effondrement des coeurs moléculaires à la population finale d’objets dans un amas. L’âge est un paramètre fondamental pour étudier la formation et l’évolution des étoiles pour plusieurs raisons: premièrement puisqu’il établit une échelle de temps sur laquelle placer les observations. Deuxièmement car il est essentiel pour convertir les luminosités en masses, avec l’aide de modèles d’évolution stellaire. Les incertitudes sur l’age de USC et r Oph se traduisant en erreurs importantes dans notre estimation de la fonction de masse, j’ai développé une stratégie d’étude de "l’âge dynamique" au moyen d’une analyse orbitale de traçage des mouvements des membres d’associations jeunes. J’ai ainsi mis au point une stratégie incluant i) les observations et la recherche de données dans les archives publiques, ii) la réduction et l’analyse des spectres échelles obtenus; iii) et l’analyse dynamique, pour déterminer l’âge d’une association. La méthodologie, développée avec l’association b Pictoris (b Pic), est prête à être appliquée à d’autres régions et en particulier à USC et r Oph. Les membres que nous avons identifiés sont par ailleurs d’excellentes cibles pour des études complémentaires telles que la recherche de disques (produit également fondamental de la formation stellaire), d’exoplanètes, de système multiples, mais aussi pour la caractérisation des atmosphères et propriétés physiques des naines brunes et des planètes errantes. [...]<br>Understanding how stars form is one of the fundamental questions which astronomy aims to answer. Currently, it is well accepted that the majority of stars form in groups and that their predominant mechanism of formation is the core-collapse. However, several mechanisms have been suggested to explain the formation of substellar objects, and their contribution is still under debate. The main goal of this thesis is to determine the initial mass function, the mass distribution of stars at birth time, in different associations and star-forming regions. The mass function constitutes a fundamental observational parameter to constrain stellar and substellar formation theories since different formation mechanisms predict different fraction of stellar and substellar objects. We used the Gaia Data Release 2 catalogue together with ground-based observations from the COSMIC-DANCe project to look for high probability members via a probabilistic model of the distribution of the observable quantities in both the cluster and background populations. We applied this method to the 30 Myr open cluster IC 4665 and the 1 - 10 Myr star-forming region Upper Scorpius (USC) and r Ophiuchi (r Oph). We found very rich populations of substellar objects which largely exceed the numbers predicted by core-collapse models. In USC, where our sensitivity is best, we found a large number of free-floating planets and we suggest that ejection from planetary systems must have a similar contribution than core-collapse in their formation. The age is a fundamental parameter to study the formation and evolution of stars and is essential to accurately convert luminosities to masses. For that, we also presented a strategy to study the dynamical traceback age of young local associations through an orbital traceback analysis. We applied this method to determine the age of the b Pictoris moving group and in the future, we plan to apply it to other regions such as USC. The members we identified with the membership analysis are excellent targets for follow-up studies such as a search for discs, exoplanets, characterisation of brown dwarfs and free-floating planets. I this thesis, we presented a search for discs hosted by members of IC 4665 and we found six excellent candidates to be imaged with ALMA or the JWST. The tools we developed, are ready to be used in other regions such as USC and r Oph, where we expect to find a larger number of disc-host stars

Full textAbstract:
In this thesis we explored the use of nuclear stellar discs as tracers of the merging history of early-type galaxies. These small structures, just a few tens to a few hundreds of parsecs across, are a common but poorly studied feature of early-type galaxies. They are formed during or shortly after merging events due to the infall of gas, which settles in a disc and leads to the formation of new stars. Initial simulations showed that they should not survive a following major merger and could, therefore, be used to trace the epoch when their host galaxies experienced their last major merger event. We produced the first census of nuclear discs and established that their incidence is 20%, fairly independent of the host-galaxy mass or galactic environment. Furthermore, we have more than doubled the sample of nuclear discs with known photometric properties, finding that they give a hint of possessing different characteristics from those of large, galactic discs. Using these nuclear discs as clocks for the assembly history of galaxies requires dating their stellar populations. By combining the use of integral-field spectroscopy with the a priori knowledge of the relative bulge- and disc-light contribution to the observed spectra, as determined by a photometric disc-bulge decomposition, we have shown that it is possible to reduce the degeneracies that affect the study of two superimposed populations and thus that the age of stellar discs can be measured more precisely. To illustrate our method, we present VLT-VIMOS data for NGC 4458, a low-mass slowly rotating early-type galaxy with a disc that we found to be at least 5-6 Gyr old. The presence of such an old central disc in such a small, slowly-rotating and, mostly likely, round galaxy is particularly puzzling and presents a challenge to existing models. Disc fragility is central to our studies and we have expanded the limited initial simulations to study it in more detail. By means of N-body simulations, we have reproduced the final stages of a galaxy encounter by exposing a nuclear disc rotating in the gravitational potential of its host bulge and central supermassive black hole to the impact of a secondary massive black hole. We explored not only major mergers (1:1 mass ratio), but also large minor mergers (1:5 and 1:10), across a variety of collision angles, and assessed the survival of the disc, as perceived by current observational limits, both for photometry and spectroscopy. As expected, the discs do not survive a major merger whereas it is in general possible to detect their presence after a 1:5 or 1:10 encounter, in particular when looking at kinematic signatures with spectroscopy. This thesis has demonstrated that nuclear discs constitute both a common and accurate tool for constraining the assembling history of nearby early-type galaxies. The advent of more sensitive integral-field spectrographs, such as MUSE, will make measuring the stellar age of nuclear discs not only more precise, but also more economical in terms of telescope time. This will allow embarking on a more systematic age dating campaign for nuclear stellar discs across a wider range of type, mass and galactic environments for their host galaxies. Combining such a census with a larger set of numerical simulations aimed at calibrating better the range of merger event that would erase any photometric or kinematic signature of a nuclear disc, should finally allow us to put firm constraints on the merging history of early-type galaxies.

La plastica è uno dei principali contaminanti degli oceani del mondo che potrebbe danneggiare anche gli ecosistemi pelagici e bentonici profondi. Tuttavia, le informazioni sul suo impatto su comunità e habitat profonsi sono ancora molto frammentarie. In questa tesi di Dottorato, è stato sviluppato un protocollo specifico per l'estrazione di microplastiche (2-1000μm) da sedimenti di ambienti profondi. Questo è risultato molto efficace nel recupero delle microplastiche (60%), pertanto è stato applicato a diversi ecosistemi bentonici per valutare la rilevanza quantitativa e qualitativa delle microplastiche. I dati ottenuti mostrano che le microplastiche sono presenti in tutti gli habitat analizzati, con concentrazioni di microplastiche < 20 μm potenzialmente molto elevate. I canyon del Mediterraneo possono fungere in alcuni casi da sink di microplastiche facilitando il loro accumulo. Le comunità dei deep sea possono essere danneggiate dalla microplastica. Infatti, questa ricerca ha rivelato che i nematodi ingeriscono frammenti di polimeri come anche il Corallium rubrum. In particolare, gli esperimenti di mesocosmo su coralli rossi, esposti a diverse concentrazioni dei più comuni polimeri trovati in ambiente marino, hanno dimostrato che questi danneggiano diverse funzioni fisiologiche e molecolari fondamentali per la loro vitalità. La plastica nei deep sea può essere trasferita lungo le reti trofiche e/o colonizzata da comunità microbiche. In particolare, è stata osservata la presenza di famiglie batteriche esclusive della plastica su due tipi di polimeri raccolti nei canyon sottomarini, lasciando ipotizzare che tali famiglie potrebbero usare queste plastiche e rappresentare loro potenziali degradatori. I risultati ottenuti nella presente tesi di Dottorato espandono la nostra conoscenza sull' inquinamento da microplastiche negli ambienti profondi e forniscono nuovi spunti per l'attuazione di strategie di conservazione in tali habitat.<br>Plastics are among the main anthropogenic impacts of the world oceans. These are also expected to affect deep-sea pelagic and benthic ecosystems but information on microplastics impacts on deep-sea communities and habitats is still very fragmentary. In the framework of this PhD thesis, a protocol for extracting microplastics (2-1000μm) was specifically developed for deep-sea sediments. This protocol was very efficient to recovery microplastics (60%), thus was applied to different benthic deep-sea ecosystems to assess the quantitative and qualitative relevance of microplastics. The data obtained revealed that microplastics are widely present in all the deep-sea habitats, with potentially very high concentrations of microplastics with size lower than 20 μm. Mediterranean canyons can act as conduits for microplastics facilitating their accumulation in deep-sea sediments, although this is not always a general rule. Deep-sea communities can be impacted by microplastics contamination. Indeed, this research revealed that nematodes ingest microplastic fragments as well as Corallium rubrum colonies. In particular, the mesocosm experiments on red corals, exposed to different concentrations of the most common plastic polymers found in marine environment, showed that microplastics harm several physiological and molecular functions need for the maintenance of their vitality. Plastics in deep-sea sediments can be transfer across trophic webs and/or colonized by microbial communities. Here, we found that exclusive bacterial families (i.e., not found in the surrounding deep-sea sediments) can grow on two types of polymers collected in deep-sea canyons, leading to hypothesize that such families could use these plastics and represent their potential degraders. Findings obtained in the present PhD thesis add new insights into the knowledge of microplastics pollution in deep-sea ecosystems and provide new cues for implementing conservation strategies of deep-sea habitats.
