description: Experiências internacionais de implementação de práticas de preservação digital em repositórios em bibliotecas, museus e arquivos são o objeto deste trabalho. Com base num levantamento bibliográfico sobre o inicio das práticas de preservação em repositórios digitais, foram identificados aspectos importantes tais como políticas de acesso, estratégias usadas, tecnologias testadas, formatos aceitos, modelo de negócios e um desconhecimento ou relativa pouca experiência com as práticas de preservação digital por parte dos gestores desses repositórios. A maioria dos repositórios registrava a dupla função de acesso e preservação, mas, poucos podiam ser considerados “arquivos obscuros” (dark archives), usados apenas para fins de preservação. A aplicação de padrões de preservação digital foi mostrando que apenas instituições de grande porte possuíam definições detalhadas do que podia ser depositado e o uso que podia ser feitos de materiais armazenados. Os gestores desses repositórios tinham algum tipo de orçamento operacional para realizar atividades de preservação. A maioria dos repositórios citados na bibliografia usava uma combinação de ferramentas comerciais e de software livre. Como conclusão, os registros analisados reforçam a necessidade ainda hoje de aplicação de mais de uma estratégia de preservação digital, do uso do modelo de referência OAIS e de auditorias oficiais no desenho de um repositório de preservação, para manter assim, a flexibilidade na integração de funções e serviços que vão além do repositório.

description: We construct an analytical approximation for the numerical black hole metric of P. Kanti, et. al. [PRD54, 5049 (1996)] in the four-dimensional Einstein-dilaton-Gauss-Bonnet (EdGB) theory. The continued fraction expansion in terms of a compactified radial coordinate, used here, converges slowly when the dilaton coupling approaches its extremal values, but for a black hole far from the extremal state, the analytical formula has a maximal relative error of a fraction of one percent already within the third order of the continued fraction expansion. The suggested analytical representation of the numerical black hole metric is relatively compact and good approximation in the whole space outside the black hole event horizon. Therefore, it can serve in the same way as an exact solution when analyzing particles' motion, perturbations, quasinormal modes, Hawking radiation, accreting disks and many other problems in the vicinity of a black hole. In addition, we construct the approximate analytical expression for the dilaton field.

Online Wideband Spectrum Sensing Using Sparsity

Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: Wideband spectrum sensing is an essential part of cognitive radio systems. Exact spectrum estimation is usually inefficient as it requires sampling rates at or above the Nyquist rate. Using prior information on the structure of the signal could allow near exact reconstruction at much lower sampling rates. Sparsity of the sampled signal in the frequency domain is one of the popular priors studied for cognitive radio applications. Reconstruction of signals under sparsity assumptions has been studied rigorously by researchers in the field of Compressed Sensing (CS). CS algorithms that operate on batches of samples are known to be robust but can be computationally costly, making them unsuitable for cheap low power cognitive radio devices that require spectrum sensing in real time. On the other hand, on line algorithms that are based on variations of the Least Mean Squares (LMS) algorithm have very simple updates so they are computationally efficient and can easily adapt in real time to changes of the underlying spectrum. In this paper we will present two variations of the LMS algorithm that enforce sparsity in the estimated spectrum given an upper bound on the number of non-zero coefficients. Assuming that the number of non-zero elements in the spectrum is known we show that under conditions the hard threshold operation can only reduce the error of our estimation. We will also show that we can estimate the number of non-zero elements of the spectrum at each iteration based on our online estimations. Finally, we numerically compare our algorithm with other on line sparsity-inducing algorithms in the literature.

description: Despite large public investments in collecting and using research data, there is little information about data use and reuse and the factors that predict use. ICPSR, a domain repository for the social sciences in the United States, has held a longstanding role in promoting data citation and archiving and disseminating social science research data and is poised to provide insight into these questions. Using the administrative data usage records of ICPSR, we estimate overall trajectories of data reuse over time -- following data from when it is first released for public use and over the next six years. We find that, for most data, data use and reuse is highest immediately after release. However, data that are uncurated get very little use even initially. Other factors that predict data use are the number of variables and subject terms related to a data collection. This suggests that data that are broader in scope may get more use. This analysis has implications for archives wishing to make smart investments in acquiring data and for allocating resources for data curation.

description: Recent developments in bigravity allow one to construct consistent theories of interacting spin-2 particles that are free of ghosts. In this framework, we propose an elementary spin-2 dark matter candidate with a mass well below the TeV scale. We show that, in a certain regime where the interactions induced by the spin-2 fields do not lead to large departures from the predictions of general relativity, such a light dark matter particle typically self-interacts and undergoes self-annihilations via 3-to-2 processes. We discuss its production mechanisms and also identify the regions of the parameter space where self-interactions can alleviate the discrepancies at small scales between the predictions of the collisionless dark matter paradigm and cosmological N-body simulations.

description: A curadoria digital e a preservação digital têm como objeto de interesse a manutenção da informação digital ao longo do tempo. Tem na literatura científica definições próximas, contudo, a curadoria se apresenta como evolução natural dos processos de preservação de recursos digitais. A preservação digital pode ser vista como método, processo e modelo. Desse modo, foi constatado que existem pontos de interseção e de diferenciação que elucidam e indicam por que um conceito apareceu depois do outro e como cada um se apresenta em face à importância dada à gestão de grandes volumes de dados, especialmente os dados científicos. Após a comparação dos dois conceitos foi possível concluir que há mais unidade no entendimento do que é curadoria digital do que os conceitos de preservação e que as áreas de atuação de ambas complementam a gestão da informação digital como um todo.

A general stability theorem with a guaranteed exponential decay-rate based on a Wirtinger-based inequality is provided. Variations of this theorem for synthesis of a controller or for an observer-based control is derived. Some numerical comparisons are proposed with existing theorems of the literature and comparable results are obtained but with an extension to stabilization.

description: A Ciência da Informação, ao longo de sua existência, tem sido um campo multi e interdisciplinar, assim como tem sofrido alterações constantes, dado seu objeto de estudo: a informação. Uma vez que este elemento não é estático e está cada vez mais ligado à tecnologia da informação, tem-se visto um desafio surgir: como garantir a permanência das bibliotecas digitais? De que maneira se pode afiançar que os terabytes gerados com cada vez mais velocidade, e nos mais variados formatos, estarão disponíveis e plenamente passíveis de uso ao longo do tempo? Este é um desafio que os profissionais da Ciência da Informação estão sendo provocados a resolver, no processo das chamadas preservação e curadoria digital. Assim, esse artigo objetiva levantar as competências que o profissional da informação deverá ter para efetivar o processo de preservação e curadoria digital. O artigo discute o aparecimento das profissões (sob a ótica da Sociologia), a necessidade do trabalho para a realização do ser humano (Psicologia) e as proficiências dos que exercem o ofício da Ciência da Informação para garantir a preservação de informações digitais nas unidades de informações.

description: The dynamics of energetic particles in strong electromagnetic fields can be heavily influenced by the energy loss arising from the emission of radiation during acceleration, known as radiation reaction. When interacting with a high-energy electron beam, today's lasers are sufficiently intense to explore the transition between the classical and quantum radiation reaction regimes. We report on the observation of radiation reaction in the collision of an ultra-relativistic electron beam generated by laser wakefield acceleration ($\varepsilon > 500$ MeV) with an intense laser pulse ($a_0 > 10$). We measure an energy loss in the post-collision electron spectrum that is correlated with the detected signal of hard photons ($γ$-rays), consistent with a quantum (stochastic) description of radiation reaction. The generated $γ$-rays have the highest energies yet reported from an all-optical inverse Compton scattering scheme, with critical energy $\varepsilon_{\rm crit} > $ 30 MeV.

description: In 2023, NeSI launched the Research Developer Cloud, an OpenStack based cloud native platform for hosting research solutions. This presentation addresses NeSI s key cloud tenants and their cloud use cases, and how NeSI and the research communities have worked together to build knowledge collaboratively and have shared insights across the various cloud tenants.

Some of the early tenants include research groups from Genomics Aotearoa, GNS Science, Manaaki Whenua   Landcare Research, and AUGMENT. As NeSI worked together with the tenants on building and hosting various solutions together, common patterns emerged around both practices as well as technology solutions. The practices include various DevOps best practices, and technologies such as Kubernetes, Terraform, and Ansible were used to help provide the tenants build solutions in a robust manner.

This talk will touch on some of the tenant specific details including machine learning build pipelines built on the cloud and how NeSI is striving to capture knowledge and insights from each experience and share them back by building blueprints of repeatable patterns for recurring problems.

description: With millions of extant species, ecdysozoans (Scalidophora, Nematoida and Panarthropoda) constitute a major portion of present-day biodiversity. All ecdysozoans secrete an exoskeletal cuticle which must be moulted periodically and replaced by a larger one. Although moulting (ecdysis) has been recognized in early Paleozoic panarthropods such as trilobites and basal groups such as anomalocaridids and lobopodians, the fossil record lacks clear evidence of ecdysis in early scalidophorans, largely because of difficulties in recognizing true exuviae. Here, we describe two types of exuviae in microscopic scalidophoran worms from the lowermost Cambrian Kuanchuanpu Formation (ca 535 Ma) of China and reconstruct their moulting process. These basal scalidophorans moulted in a manner similar to that of extant priapulid worms, extricating themselves smoothly from their old tubular cuticle or turning their exuviae inside out like the finger of a glove. This is the oldest record of moulting in ecdysozoans. We also discuss the origin of ecdysis in the light of recent molecular analyses and the significance of moulting in the early evolution of animals.
title: Patterns of subspecies diversity in the giraffe, Giraffa camelopardalis (L. 1758): comparison of systematic methods and their implications for conservation policy
Creators: name: Seymour, Russell
Publisher: name: University of Kent
Year: 2022

description: This thesis examines the subspecific taxonomic status of the giraffe and considers the role of formal taxonomy in the formulation of conservation policy. Where species show consistent. geographically structured phenotypic variation such geographic patterns may indicate selective forces (or other population-level effects) acting. upon local populations. These consistent geographic patterns may be recognised formally as subspecies and may be of interest in single or multi-species biodiversity or biogeography studies for delimiting areas of conservation priority. Subspecies may also be used in the formulation of management policies and legislation. Subspecies are, by definition, allopatric. This thesis explicitly uses methodology of systematic biology and phylogenetic reconstruction to investigate patterns of variation between geographic groups. The taxonomic status of the giraffe is apposite for review. The species provides three independent data sets that may be analysed quantitatively for geographic structure; pelage patterns, morphology and genetics. Museum specimens. grouped according to geographic origin, were favoured for study as more than one type of data was often available for an individual. Population aggregation analysis of forty pelage pattern characters maintained six separate subspecies, while agglomerating some neighbouring populations into a subspecies. A 'traditional' morphometric approach, using multivariate statistical analysis of adult skull measurements, was complemented by a geometric morphometric approach; landmarkrestricted eigenshape analysis. Four morphologically distinct groups were recognised by both morphological analyses. Phylogenetic analysis of mitochondrial DNA control region sequences indicates five major cIades. Nested cIade analysis identifies population fragmentation, range expansion and genetic isolation by distance as contributing to the genetic structure of the giraffe. The results of the analyses show remarkable congruence. These results are discussed in terms of the formulation of conservation policy and the differing requirements of'blological and legal classification systems. The value of a formal taxonomic framework to the recognition, and subsequent conservation, of biodiversity is emphasised.

description: While government websites are essential for accessing government information, data about these government websites is not always easy to access or interpret. The U.S. Digital Analytics Program (DAP), at analytics.usa.gov, captures anonymous daily website usage data for over 5,000 government websites, and yet the DAP provides only a 30-day archive of their data. This presentation provides an initial analysis of a unique dataset of two years of DAP data downloaded regularly by the presenters between 2016 and 2018. This dataset allows for an investigation into trends of government website usage, including content from the U.S. Centers for Disease Control and Prevention, the National Weather Service, the Occupation Safety and Health Administration, the Department of Agriculture, and many others. The presentation will explore the degree of variability in such website usage data over time and will also raise questions about best practices for archiving both DAP data and the website page content included in DAP. The presentation will also consider the relevance of DAP data to wider discussions about preserving government website content and potential opportunities for creating more robust practices for collecting and archiving government website usage data.
Universal scaling and nonlinearity of aggregate price impact in financial markets

description: How and why stock prices move is a centuries-old question still not answered conclusively. More recently, attention shifted to higher frequencies, where trades are processed piecewise across different timescales. Here we reveal that price impact has a universal non-linear shape for trades aggregated on any intra-day scale. Its shape varies little across instruments, but drastically different master curves are obtained for order-volume and -sign impact. The scaling is largely determined by the relevant Hurst exponents. We further show that extreme order flow imbalance is not associated with large returns. To the contrary, it is observed when the price is "pinned" to a particular level. Prices move only when there is sufficient balance in the local order flow. In fact, the probability that a trade changes the mid-price falls to zero with increasing (absolute) order-sign bias along an arc-shaped curve for all intra-day scales. Our findings challenge the widespread assumption of linear aggregate impact. They imply that market dynamics on all intra-day timescales are shaped by correlations and bilateral adaptation in the flows of liquidity provision and taking.

description: Observations of relaxed, massive and distant clusters can provide important tests of standard cosmological models e.g. using the gas mass fraction. We study the very luminous, high redshift ($z=0.902$) galaxy cluster ClJ120958.9+495352 using XMM-Newton data and measure the temperature profile and cooling time to investigate the dynamical status with respect to the presence of a cool core as well as global cluster properties. We use HST weak lensing data to estimate its total mass and determine the gas mass fraction. We perform a spectral analysis using an XMM-Newton observation of 15ks cleaned exposure time. As the treatment of the background is crucial, we use two different approaches to account for the background emission to verify our results. We account for point-spread-function effects and deproject our results to estimate the gas mass fraction of the cluster. We measure weak lensing galaxy shapes from mosaic HST imaging and select background galaxies photometrically in combination with imaging data from the William Herschel Telescope. The X-ray luminosity of ClJ120958.9+495352 in the 0.1-2.4keV band estimated from our XMM-Newton data is $L_X = (13.4_{-1.0}^{+1.2})\times10^{44}$erg/s and thus it is one of the most X-ray luminous clusters known at similarly high redshift. We find clear indications for the presence of a cool core from the temperature profile and the central cooling time, which is very rare at such high redshifts. Based on the weak lensing analysis we estimate a cluster mass of $M_\mathrm{500}/10^{14}M_\odot=4.4^{+2.2}_{-2.0}(\mathrm{stat.})\pm0.6(\mathrm{sys.})$ and a gas mass fraction of $f_\mathrm{gas,2500} = 0.11_{-0.03}^{+0.06}$ in good agreement with previous findings for high redshift and local clusters.

description: Changes in phytoplankton community composition potentially affect the entire marine food web. Because of seasonal cycles and inter-annual variations in species composition, long-term monitoring, covering many sequential years, is required to establish a baseline study and to reveal long-term trends. The current study describes the phytoplankton biomass variations and species composition in relation to hydrographic and meteorological conditions in the Raunefjord, western Norway, over a 6-year period from 2001 to 2006. The extent of inflow or upwelling in the fjord varied from year to year and resulted in pronounced differences in water column stability. The annual phytoplankton community succession showed some repeated seasonal patterns, but also high variability between years. Two to four diatom blooms were observed per year, and the spring blooms occurring before water column stratification in March were dominated by Skeletonema marinoi and Chaetoceros socialis, and other Chaetoceros and Thalassiosira spp. Blooms of the haptophytes Phaeocystis pouchetii and Emiliania huxleyi were irregular and in some years totally absent. Although E. huxleyi was present all year round it appeared in bloom concentrations only in 2003, when the summer was warm and the water column characterized by high surface temperatures and pronounced stratification. The annual average abundance of both diatoms and flagellates increased during the six years. Despite the high variation from year to year, our investigation provides valuable knowledge about annual phytoplankton community patterns in the region, and can be used as a reference to detect possible future changes.

description: Bangladesh Bureau of Statistics (BBS) plans to convert Census/Survey microdata into next generation technology formats using IBM proprietary technology. After Bangladesh’s independence, there is a rich repository of statistical information in IBM 360 to ES/9000 mainframe 8600 tapes, dating back to the late 1970s and early 2000s. The overarching objective is to strengthen the prevailing national statistical archiving system. BBS will be making available this large volume of converted data to the citizens of Bangladesh (and if needed, the world community) so that academic and scholarly debates can take place with cognizance of this historical data. This is a big step towards dissemination of Big Data covering Bangladesh’s economic developmental trend since its birth in 1971. By revisiting time series data, it is hoped that well-informed and meticulous policies can be designed and formulated in the future. Most fundamentally, availability and easy accessibility of such a large volume of Big Data will inspire reassessing economic theories and indicators of development informing Bangladesh’s position in global rankings such as the Sustainable Development Goals (SDGs).
title: Cooking the wild: the role of the Lundayeh of the Ulu Padas, (Sabah, Malaysia) in managing forest foods and shaping the landscape
Creators: name: Hoare, Alison L.
Publisher: name: University of Kent
Year: 2022

description: This thesis provides an account of the Lundayeh subsistence system as found in the villages of Long Pasia and Long Mio, situated in the Ulu Padas, Sabah. The research focuses on Lundayeh food and diet, describing the diversity of resources used and the importance of forest foods. Comparison with studies from elsewhere in Borneo suggests that there are many similarities between Lundayeh practices and those of other highland peoples. These data are used to critically examine the concepts of 'wild' and 'wilderness', considering whether these concepts are meaningful, either analytically or for the Lundayeh. Investigation of the way in which the Lundayeh manipulate and manage their resources suggests that they have had a profound influence on their environment. Consequently, the Ulu Padas cannot be described as a wilderness, nor its resources as wild. The extent to which the Lundayeh themselves construct the categories of 'wild' and 'cultivated' foods is investigated through examining how these resources are owned, and their different roles in the diet. These data suggest that the Lundayeh recognise that there is no simple dichotomy of 'wild' and 'cultivated', but rather, that there is a gradation between these two categories. There is also evidence to suggest that the Lundayeh do not consider any resources as wild, in the sense of being uninfluenced by people. The environmental perceptions of the Lundayeh are also investigated, and how these have been shaped by their particular way of life, history, beliefs and knowledge systems. It is apparent that for the Lundayeh, the Ulu Padas is a cultural landscape. However, this is changing, as a result of recent social and environmental changes. This thesis concludes by examining the impact of changing perceptions on how the Lundayeh are managing their environment, and on their attitudes towards conservation.

description: With millions of extant species, ecdysozoans (Scalidophora, Nematoida and Panarthropoda) constitute a major portion of present-day biodiversity. All ecdysozoans secrete an exoskeletal cuticle which must be moulted periodically and replaced by a larger one. Although moulting (ecdysis) has been recognized in early Paleozoic panarthropods such as trilobites and basal groups such as anomalocaridids and lobopodians, the fossil record lacks clear evidence of ecdysis in early scalidophorans, largely because of difficulties in recognizing true exuviae. Here, we describe two types of exuviae in microscopic scalidophoran worms from the lowermost Cambrian Kuanchuanpu Formation (ca 535 Ma) of China and reconstruct their moulting process. These basal scalidophorans moulted in a manner similar to that of extant priapulid worms, extricating themselves smoothly from their old tubular cuticle or turning their exuviae inside out like the finger of a glove. This is the oldest record of moulting in ecdysozoans. We also discuss the origin of ecdysis in the light of recent molecular analyses and the significance of moulting in the early evolution of animals.

He was on the USS Missouri for the surrender of Japan at the end of the war and was captured in some of the photographs taken at the time."Walter William Brackenridge - can be seen in the full photograph of the ceremony of the surrender of Japan which is currently in the Singapore War Museum.
Baryon Number and Lepton Universality Violation in Leptoquark and Diquark Models

description: We perform a systematic study of models involving leptoquarks and diquarks with masses well below the grand unification scale and demonstrate that a large class of them is excluded due to rapid proton decay. After singling out the few phenomenologically viable color triplet and sextet scenarios, we show that there exist only two leptoquark models which do not suffer from tree-level proton decay and which have the potential for explaining the recently discovered anomalies in B meson decays. Both of those models, however, contain dimension five operators contributing to proton decay and require a new symmetry forbidding them to emerge at a higher scale. This has a particularly nice realization for the model with the vector leptoquark $(3,1)_{2/3}$, which points to a specific extension of the Standard Model, namely the Pati-Salam unification model, where this leptoquark naturally arises as the new gauge boson. We explore this possibility in light of recent B physics measurements. Finally, we analyze also a vector diquark model, discussing its LHC phenomenology and showing that it has nontrivial predictions for neutron-antineutron oscillation experiments.

description: A preservação digital é uma necessidade real a ser atendida pelos repositórios institucionais, responsáveis pela preservação da produção científica de instituições de ensino e pesquisa. Entretanto, devido a constante evolução da área, a busca pelo domínio do conhecimento e das melhores práticas por parte dos responsáveis pela preservação digital é uma tarefa complexa. As pesquisas, práticas e soluções em preservação digital abordam problemas pontuais, como formatos, curadoria, modelos de referência, autenticidade, políticas e planos de preservação, ferramentas, etc., enquanto que os implementadores necessitam de uma visão integrada, geral, contextualizada e aplicável. Este artigo enfoca a implantação da preservação digital em repositórios, sob a perspectiva da equipe responsável pelo projeto, no que diz respeito aos conhecimentos e práticas necessárias. Inicialmente define e contextualiza a preservação digital em repositórios. A seguir, apresenta um modelo conceitual de preservação digital, sintetizado a partir de modelos conceituais e de fundamentos que foram desenvolvidos em projetos influentes na área, o qual permite identificar, de forma geral, os principais domínios de conhecimento em preservação digital. Finalmente, aspectos representados no modelo são discutidos no contexto da atuação das equipes na implantação da preservação digital em repositórios, oferecendo recomendações, guias ou exemplos que podem ser úteis para implantação da preservação digital. Aponta para a necessidade de se fortalecer a relação entre o domínio de conhecimentos em preservação digital em repositórios com as práticas dos inúmeros projetos desenvolvidos globalmente.
Wrong sign Yukawa coupling of the 2HDM plus a singlet scalar dark matter confronted with dark matter and Higgs data

description: In the framework of type-II two-Higgs-doublet model with a scalar dark matter ($S$), we examine the wrong sign Yukawa coupling of the 125 GeV Higgs which is the only portal between the dark matter and SM sectors. After imposing the constraints from the Higgs searches at the LHC and dark matter experiments, we obtain some interesting observables: (i) The theory, oblique parameters, and the Higgs searches at the LHC can impose stringent constraints on $\tanβ$ in the case of the wrong sign Yukawa coupling of the 125 GeV Higgs. For example, for $m_H=600$ GeV and 140 GeV $-0.82$. (iv) The Fermi-LAT limits exclude most of samples in the range of 62.5 GeV $

description: We consider model-based clustering methods for continuous, correlated data that account for external information available in the presence of mixed-type fixed covariates by proposing the MoEClust suite of models. These models allow different subsets of covariates to influence the component weights and/or component densities by modelling the parameters of the mixture as functions of the covariates. A familiar range of constrained eigen-decomposition parameterisations of the component covariance matrices are also accommodated. This paper thus addresses the equivalent aims of including covariates in Gaussian parsimonious clustering models and incorporating parsimonious covariance structures into all special cases of the Gaussian mixture of experts framework. The MoEClust models demonstrate significant improvement from both perspectives in applications to both univariate and multivariate data sets. Novel extensions to include a uniform noise component for capturing outliers and to address initialisation of the EM algorithm, model selection, and the visualisation of results are also proposed.

description: Mark Walsh brought along two medals. "I think they were my grandfather's. They were clearly from the Second World War, for service. They are for general service. My grandfather on my mum's side was an engineer - Edward Ellis.From my father's side they were based for service in Italy or even North Africa. My other grandfather was Edward Walsh. I believe he was a skilled engineer. They were both English and based in Leeds, which is where I am from. They both died just before I was born (early 1970s)."

description: A Universidade Federal da Bahia (UFBA), que tem sua origem no século XIX, acumula acervos significativos e representativos de diversas áreas do conhecimento. Esta situação estimulou um projeto que estabeleceu como objetivo políticas específicas de manutenção e preservação do seu acervo. Em 2015, iniciou o mapeamento dos bens culturais e artístico, móveis e imóveis nos campi da UFBA, em Salvador tendo como resultado o inventário, que apresenta componentes de identificação de tipologias e de classificação individual, do estado de conservação dos exemplares das diversas unidades acadêmicas, de prioridades no âmbito da conservação, preservação e restauração do patrimônio. O inventário, de método quantitativo e qualitativo, compõe uma base de dados eletrônica, atualizada, de acesso simples e democrático, que permite acesso à comunidade acadêmica, aos pesquisadores e a sociedade em geral. Quanto aos livros raros, localizados na coordenação Lugares de Memória, foram cadastrados 398 obras raras dos Séculos XVI a XVIII. Falta realizar inventário das coleções e livros com características especiais dos Séculos XVIII, XIX e XX. Ao estimar os resultados desse projeto, vale o investimento nas proposições apresentadas acima, pois eles não só favorecem a UFBA, mas também beneficia a sociedade, uma vez que esta instituição passará a ser um polo disseminador e promotor de políticas de preservação de acervos e salvaguarda do patrimônio cultural, que estarão disponíveis no repositório institucional para consulta da comunidade interna e externa.
