description: Digital tabletops are powerful interaction mediums. As a virtual medium their computational capabilities allow the user to digitally explore, transform and embellish the input content to gain further insights about the pertinent information. On the other hand, as a physical medium, their form factor inherently supports collaboration and presents opportunities to place other physical objects atop to assist and enhance the exploration experience. In this thesis, we propose the use of tabletops as an interaction medium to explore reservoir post-processing flow simulation models using virtual content - visualizations and a physical agent - Spidey: a tabletop robotic assistant. We discuss results that emerged from evaluating each of the prototypes, presenting the potential of each of these concepts and their applicability to the domain of reservoir engineering. With the Spidey testbed we explored the notion of proxemics between a user and a robotic tabletop assistant and performed a user study in which participants interacted with Spidey. Thus in the results, we also discuss the proxemics results reflecting on the interaction between people and tabletop robots.

description: Frozen orbits are always important foci of orbit design because of their valuable characteristics that their eccentricity and argument of pericentre remain constant on average. This study investigates quasi-circular frozen orbits and examines their basic nature analytically using two different methods. First, an analytical method based on Lagrangian formulations is applied to obtain constraint conditions for Martian frozen orbits. Second, Lie transforms are employed to locate these orbits accurately, and draw the contours of the Hamiltonian to show evolutions of the equilibria. Both methods are verified by numerical integrations in an 80\times80 Mars gravity field. The simulations demonstrate that these two analytical methods can provide accurate enough results. By comparison, the two methods are found well consistent with each other, and both discover four families of Martian frozen orbits: three families with small eccentricities and one family near the critical inclination. The results also show some valuable conclusions: for the majority of Martian frozen orbits, argument of pericentre are kept at 270 degrees because J3 has the same sign with J2; while for a minority of ones with low altitude and low inclination, argument of pericentre are possible to be kept at 90 degrees because of the effect of the higher degree odd zonals; for the critical inclinations cases, argument of pericentre can also be kept at 90 degrees. It is worthwhile to note that there exist some special frozen orbits with extremely small eccentricity, which could provide much convenience for reconnaissance. Finally, the stability of Martian frozen orbits is estimated based on the trace of the monodromy matrix. The analytical investigations can provide good initial conditions for numerical correction methods in the more complex models.

description: Este estudo procura definir uma metodologia capaz de aplicar para Portugal o projeto MediaAcT, que compara os diversos sistemas de Media Accountability na União Europeia como indicador para o pluralismo na Europa. De facto, o impacto dos mecanismos de regulação nos media tem sido muito debatido, mas pouco estudado sistematicamente. Neste sentido, o MediaAcT, assentando na teoria económica, procura determinar e fornecer dados empíricos confiáveis, capazes de gerar um debate sustentado sobre este tema. A regulação dos média ganha ainda uma maior relevância perante as alterações provocadas pela Era Digital, que dotou o indivíduo / cidadão de instrumentos que lhe permitem não só interferir nos conteúdos produzidos pelos média, como também ser produtor desses conteúdos. Este artigo procura assim identificar os fatores macro, meso e micro que influenciam o trabalho jornalístico e as suas responsabilidades éticas. Estes fatores de influencia são agrupados em sete patamares distintos: jornalista (individualmente); redação; organização da empresa; cultura profissional; sistema de media; fatores externos de contexto; globalização. Para além disso, a audiência e a educação do jornalista são considerados fatores transversais, uma vez que parecem influenciar o comportamento do jornalista nos restantes níveis referidos. É importante perceber o peso de cada um destes fatores no trabalho jornalístico e a interdependência entre eles. A metodologia utilizada tem como base um inquérito quantitativo standard a submeter aos jornalistas de cada um dos países parceiros, via internet. A amostra é estratificada, por forma a ser representativa da realidade jornalística de cada país.

description: Edge-on spiral galaxies offer a unique perspective on the vertical structure of spiral disks, both stars and the iconic dark dustlanes. The thickness of these dustlanes can now be resolved for the first time with Herschel in far-infrared and sub-mm emission. We present NHEMESES, an ongoing project that targets 12 edge-on spiral galaxies with the PACS and SPIRE instruments on Herschel. These vertically resolved observations of edge-on spirals will impact on several current topics. First and foremost, these Herschel observations will settle whether or not there is a phase change in the vertical structure of the ISM with disk mass. Previously, a dramatic change in dustlane morphology was observed as in massive disks the dust collapses into a thin lane. If this is the case, the vertical balance between turbulence and gravity dictates the ISM structure and consequently star-formation and related phenomena (spiral arms, bars etc.). We specifically target lower mass nearby edge-ons to complement existing Herschel observations of high-mass edge-on spirals (the HEROES project). Secondly, the combined data-set, together with existing Spitzer observations, will drive a new generation of spiral disk Spectral Energy Distribution models. These model how dust reprocesses starlight to thermal emission but the dust geometry remains the critical unknown. And thirdly, the observations will provide an accurate and unbiased census of the cold dusty structures occasionally seen extending out of the plane of the disk, when backlit by the stellar disk. To illustrate the NHEMESES project, we present early results on NGC 4244 and NGC 891, two well studies examples of a low and high-mass edge-on spiral.

description: Several methods are being used to recover buried heavy oil or bitumen deposits within oil-sands reservoirs. Cyclic Steam Stimulation (CSS) has been a commercial recovery process since the mid 1980’s in the Cold Lake area in northeast Alberta. Also, Several Steam-Assisted Gravity Drainage (SAGD) projects are in operation in different types of reservoirs in the Cold Lake area. There is a debate over whether CSS is more efficient in the Cold Lake reservoirs or SAGD. It is very important for producers to know broadly about the performance and efficiency of the oil recovery process. This helps them to select the proper recovery process. The main objective of this study was aimed to review and compare the performance and efficiency of the CSS and SAGD processes in Cold Lake area. In the current survey, the field data gathered since the start of the operation until almost the present time and the performance comparison were carried out based on the acquired data. Then two robust models were built using CMG-STARS for both CSS and SAGD processes. In both models, averaged reservoir properties that represent mean values of Cold Lake reservoir was incorporated. The production profile of both processes were history matched and the validity of the models confirmed through sensitivity studies. The performance indicators such as cumulative steam oil ratio, recovery factor and cumulative produced oil values were obtained from the models and compared. Finally, sensitivity scenarios were performed on both models to evaluate and compare the performance of each reservoir under different recovery mechanism.

description: We report electronic transport on n-type silicon Single Electron Transistors (SETs) fabricated in Complementary Metal Oxide Semiconductor (CMOS) technology. The n-MOSSETs are built within a pre-industrial Fully Depleted Silicon On Insulator (FDSOI) technology with a silicon thickness down to 10 nm on 200 mm wafers. The nominal channel size of 20 $\times$ 20 nm$^{2}$ is obtained by employing electron beam lithography for active and gate levels patterning. The Coulomb blockade stability diagram is precisely resolved at 4.2 K and it exhibits large addition energies of tens of meV. The confinement of the electrons in the quantum dot has been modeled by using a Current Spin Density Functional Theory (CS-DFT) method. CMOS technology enables massive production of SETs for ultimate nanoelectronics and quantum variables based devices.

The carapace of the first stage crab (0.87–0.89 mm SL) has a longitudinal reddish pigmented area at the middle portion of the posterior two-thirds (Fig. 5 A, B); it also exhibits a reddish pigmented patch on the middle portion of each side wall of the shield. The reddish pigmented area and patches develop as a longitudinal brown stripe at the middle portion of the carapace and a brown band at the anterior lower part of each side of the shield, respectively, in juveniles with an SL of> 1 mm after one month of age (Fig. 5 C–F, 6A, B). The second and third pereiopods of the first stage crab are reddish (Fig. 5 A). After one month of age, the shield and pereiopods generally show a whitish/creamy color and gradually exhibit a greyish color (Fig. 5 C, E, 6A–D). The body color of the live crab appears to be darker than that of the specimens (Fig. 6 A, D).

description: Diagnostic and screening studies in ophthalmology frequently involve binocular data where pairs of eyes are evaluated, through some diagnostic procedure, for the presence of certain diseases or pathologies. It is usually sufficient in practice that at least one eye is positively diagnosed for the patient to be sent for further and more extensive eye examination. More relevant diagnostic accuracy measures in these cases are therefore the probability of at least one correct positive diagnosis in patients with one or both eyes truly diseased and the probability of two correct negative diagnoses for patients with both eyes truly un-diseased. The former is analogous to sensitivity and the latter to specificity. Predictive values may be similarly re-defined. The thesis proposes these new sensitivity and specificity measures as alternatives to conventional ones for paired binocular binary diagnostic data arising from screening studies with cross-sectional sampling. The measures are defined for flexible models based on copulas and extensions of existing models for correlated binary data. The proposed methodology is illustrated with data from a study on diabetic retinopathy.

description: A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices using sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations. During RF transmission energy consumed by critically energy-constrained sensor nodes in a WSN is related to the life time system, but the life time of the system is inversely proportional to the energy consumed by sensor nodes. In that regard, modulated backscattering (MB) is a promising design choice, in which sensor nodes send their data just by switching their antenna impedance and reflecting the incident signal coming from an RF source. Hence wireless passive sensor networks (WPSN) designed to operate using MB do not have the lifetime constraints. In this we are going to investigate the system analytically. To obtain interference-free communication connectivity with the WPSN nodes number of RF sources is determined and analyzed in terms of output power and the transmission frequency of RF sources, network size, RF source and WPSN node characteristics. The results of this paper reveal that communication coverage and RF Source Power can be practically maintained in WPSN through careful selection of design parameters

Mother of Power, Mother of Kings: Reading Royal Ideology in the Devī Māhātmya

subject: Hindu Goddess

description: The Sanskrit narrative text Devī Māhātmya, “The Greatness of The Goddess” (henceforth DM), extols the triumphs of an all-powerful Goddess, Durgā, over universe-imperiling demons. These exploits are embedded in an intriguing frame narrative: a deposed king solicits the counsel of a forest-dwelling ascetic, who narrates the tripartite acts of Durgā which comprise the main body of the text. Why is this? This study argues that the DM’s frame narrative cleverly engages a dichotomy at the heart of Hinduism: the opposing ideals of asceticism and kingship. These ideals comprise two strands of what is referred to herein as the brāhmaṇic double helix. This work decodes the symbolism of encounters between forest hermits and exiled kings through the lens of the dharmic double helix, demonstrating the extent to which this common narrative trope masterfully encodes the ambivalence of brāhmaṇic ideology. Engaging the tension between the moral necessity for nonviolence and the sociopolitical necessity for violence, this project deconstructs the ideological ambivalence throughout the DM to demonstrate that its frame narrative invariably sheds light on its core content. Its very structure serves to emphasize a theme that prevails throughout the text, one inalienable to the rubric of the episodes themselves: sovereignty on both cosmic and mundane scales. Acknowledging narrative’s paramount function of encoding ideology, this project locates the DM ideologically more so than historically. To draw from Umberto Eco’s narrative theory, this study argues that the DM’s model reader is not only expected to be equipped with the ideological savvy outlined above, but also with a certain structural savvy. The former of these interpretational tools pertains to content, while the latter pertains to form. Regarding the latter, this research demonstrates that the DM’s narrative enframement is an indispensable component of a complex, consciously orchestrated, meaningful narrative structure, one purposefully geared towards encoding ideology and eliciting interpretation through structural cues. It constitutes a synchronic study of the glories of the Goddess, one that necessarily makes sense of the text as a whole, frame and all. As emphasized by its subtitle, this thesis is not merely about royal ideology in the DM, it is equally about how to read that ideology.

The shield of the first stage crab (0.97–1.03 mm SL) has faint brownish pigments (Fig. 7 A, B); they develop as two longitudinal brown bands/patches on the middle portion and a dark brown band at the anterior lower portion of each side wall of the whitish/creamy shield in juveniles with an SL of> 1.2 mm after one month of age (Fig. 7 D–F, 8A–D, G). The ocular peduncle of the first stage crab has a brownish pigment area ventrally (Fig. 7 C), and it gradually develops to a dark brown color after one month of age (Fig. 8 E). The ocular acicles and the upper edge of the shield exhibit a brown color in juveniles with an SL of> 1.3 mm after two months of age (Fig. 7 F, 8A). The second and third pereiopods of the first stage crabs are reddish brown, excluding the distal and proximal parts of each segment; they appear to have whitish rings at the boundaries between segments (Fig. 7 A, B). The palm of the left cheliped begins to develop brownish pigment areas on the upper and lower parts after one month of age (Fig. 7 D, E); specifically, the pigment on the lower part develops as a distinct large brown patch, and the palm appears to have a longitudinal white stripe on the middle portion (Fig. 7 F, 8C, D, F, G). The brownish bands also develop on the carpi and meri of the chelipeds, and the bands of the pereiopods become dark brown (Fig. 7 D–F, 8C, D, F, G).

description: Analytical Gas Chromatography (GC) separation techniques are constantly being developed to reduce analysis time and cost as well as improve sensitivity and accuracy. One such development is the fabrication of miniaturized microfluidic columns for use in GC. There are vast reports of miniaturized columns fabricated in silicon and even other polymeric materials. While these devices show good separation efficiency, they lack physical robustness and the thermal stability demanded by GC. Alternatively, Low Temperature Co-fired Ceramics (LTCC) and titanium are novel materials that show promise for use in microfluidic GC column fabrication. They offer advantages such as low cost, ease of fabrication, and additionally, these materials are quite strong and can withstand the high temperatures required in GC. LTCC together with titanium metals have been studied and characterized as alternative platforms for microfluidic GC in this thesis. Both LTCC and titanium tiles produced good results that compared well with commercially available GC columns. For example, a 7.5m long channel within an 11 cm x 5.5 cm LTCC tile under optimum conditions generated theoretical plates for a dodecane test analyte of about 14327 compared to 4507 for a 7.5 m long commercial capillary column. Similarly, a 15m long channel within a 15 cm x 8 cm titanium tile produced 10377 plates for the same test analyte. Both of these tiles showed high resolving power, yielding benzene – toluene resolutions of about 14.07 and 8.29 respectively for LTCC and titanium. Peak capacity was also probed using temperature programming with a simple nC8 – nC20 alkane mixture. A cumulative peak capacity of about 53 was obtained for the LTCC tile while the titanium tile gave a value of 48. Polar analyte separations on both often produced peaks with a greater degree of tailing. Additionally, packed columns fabricated on these materials were also investigated, and produced good separation efficiency with negligible flow restriction. For example, a 10 cm long channel within a 5.5 cm x 2.5 cm LTCC tile packed with 5µm C18 particles generated 2710 plates per meter. Likewise, a 10 cm long channel within a 9 cm x 5 cm titanium tile packed with 1.7µm C18 particles also produced 8430 plates per meter; a three fold increase. Neither displayed any adverse effects from operating the tiles up to 60 atm of carrier gas pressure. Results indicate that LTCC and titanium make excellent platforms for microfluidic GC. Further exploration of their properties in this area will be useful.

description: In 2003 COHN and UMANS introduced a group-theoretic approach to fast matrix multiplication. This involves finding large subsets of a group $G$ satisfying the Triple Product Property (TPP) as a means to bound the exponent $ω$ of matrix multiplication. Recently, Hedtke and Murthy discussed several methods to find TPP triples. Because the search space for subset triples is too large, it is only possible to focus on subgroup triples. We present methods to upgrade a given TPP triple to a bigger TPP triple. If no upgrade is possible we use reduction methods (based on random experiments and heuristics) to create a smaller TPP triple that can be used as input for the upgrade methods. If we apply the upgrade process for subset triples after one step with the upgrade method for subgroup triples we achieve an enlargement of the triple size of 100 % in the best case.

description: We study the temperature scale of the Kondo screening of a magnetic impurity which hybridizes with a two-dimensional electron gas in the presence of the Rashba spin-orbit interaction. The problem is mapped to an effective single-band impurity model with a hybridization function having an inverse-square-root divergence at the bottom of the band. We study the effect of this divergence on the Kondo screening. The problem is solved numerically without further approximations using the numerical renormalization group technique. We find that the Rashba interaction leads to a small variation of the Kondo temperature (increase or decrease) which depends on the values of the impurity parameters.

description: Atualmente é difícil ignorar que a Internet e a sua utilização são característica na vida de muitos cidadãos espalhados pelo mundo. Consequentemente, a sua utilização enquanto fonte de informação e plataforma de disseminação política está a ganhar maior importância a cada dia que passa (Borgida & Stark, 2004). Estudos recentes, como o de Túnez e Sixto (2011), sugerem que as redes sociais digitais marcam um novo ambiente e suporte comunicativo para os cidadãos e para as organizações num modelo multi-direcional, mas com um compromisso de interação. Até à data, a utilização dos sites de redes sociais, nomeadamente o Facebook, como plataforma e ferramenta de comunicação política pelos principais atores políticos em Portugal não tem sido muito abordada em investigações empíricas. Assim, o objetivo desta investigação é perceber de que forma os principais atores políticos em Portugal (o Presidente da República, o Primeiro-ministro e os líderes dos partidos com assento parlamentar), usam os perfis nas redes sociais digitais enquanto plataforma de comunicação política e de disseminação das suas ideias. Através de uma análise do conteúdo dos perfis oficiais do Facebook destes indivíduos procurou-se analisar, não só as características do perfil, mas também o nível de compromisso 2.0 de cada um deles (Túñez & Sixto, 2011). O conceito de compromisso 2.0 baseia-se na ideia de que a participação em ambientes digitais não é alcançada apenas através da sua presença nestes meios, mas que também exige uma contribuição ativa por parte dos criadores e utilizadores, através da troca de opiniões e conteúdos. Consequentemente, a ideia de política 2.0 requer a capacidade do político em se abrir aos cidadãos, em encorajar a sua participação e valorizar os seus comentários e opiniões (Túñez & Sixto, 2011). A investigação que todas as figuras analisadas demonstram um alto compromisso para com o seu perfil de Facebook, mas que este tende a esmorecer quando não está em curso nenhuma campanha eleitoral ou quando fazem parte do governo. Também sugere que os líderes com idade mais avançada não se sentem tão à vontade com esta plantaforma, já que Jerónimo de Sousa e o Presidente da República exibem níveis de “compromisso 2.0” nulo ou um mural raramente atualizado.

description: Vehicular sensor network (VSN) is an emerging technology, which combines wireless communication offered by vehicular ad hoc networks (VANET) with sensing devices installed in vehicles. VSN creates a huge opportunity to extend the road-side sensor infrastructure of existing traffic control systems. The efficient use of the wireless communication medium is one of the basic issues in VSN applications development. This paper introduces a novel method of selective data collection for traffic control applications, which provides a significant reduction in data amounts transmitted through VSN. The underlying idea is to detect the necessity of data transfers on the basis of uncertainty determination of the traffic control decisions. According to the proposed approach, sensor data are transmitted from vehicles to the control node only at selected time moments. Data collected in VSN are processed using on-line traffic simulation technique, which enables traffic flow prediction, performance evaluation of control strategies and uncertainty estimation. If precision of the resulting information is insufficient, the optimal control strategy cannot be derived without ambiguity. As a result the control decision becomes uncertain and it is a signal informing that new traffic data from VSN are necessary to provide more precise prediction and to reduce the uncertainty of decision. The proposed method can be applied in traffic control systems of different types e.g. traffic signals, variable speed limits, and dynamic route guidance. The effectiveness of this method is illustrated in an experimental study on traffic control at signalised intersection.

description: O desenvolvimento da Internet nos últimos anos tem alterado a dinâmica como os cidadãos acessam a informação. Cada vez mais os conteúdos são difundidos pela web, principalmente quando os media tradicionais passam a ser mais presentes na rede, produzindo informação com instantaneidade (característica da web) e desenvolvendo uma linguagem para os novos media, nomeadamente as redes sociais, como o Facebook, objeto de estudo deste trabalho. Entender como se dá este processo, bem como se os cidadãos aproveitam estes espaços e as potencialidades oferecidas pela plataforma Facebook para debater e discutir assuntos de relevância social, é um dos objetivos deste trabalho. É intenção também perceber como a Internet permitiu o acesso de novos atores sociais no debate público e político, bem como pode ser uma poderosa ferramenta de participação social.

description: How a youth experiences acculturation shapes the ability of immigrant and refugee youth to feel safe, included, and hopeful about their future. The purpose of this study is to deepen social workers’ understanding about integrating forum theatre as therapy with at-risk immigrant and refugee youth by exploring insights that arose from youths’ participation in forum theatre. To gain this understanding, this study was completed using the generic qualitative approach, interviewing six Calgary respondents about their time settling in Canada and about their participation in forum theatre. Findings suggest that forum theatre could be a useful intervention to generate dialogue and inspire personal or social change. Directions for future research include exploring gender constructions through forum theatre or investigating forum theatre as therapy within a social work setting or practice.
Proposal for a GHz count rate near-IR single-photon detector based on a nanoscale superconducting transition edge sensor

description: We describe a superconducting transition edge sensor based on a nanoscale niobium detector element. This device is predicted to be capable of energy-resolved near-IR single-photon detection with a GHz count rate. The increased speed and sensitivity of this device compared to traditional transition edge sensors result from the very small electronic heat capacity of the nanoscale detector element. In the present work, we calculate the predicted thermal response time and energy resolution. We also discuss approaches for achieving efficient optical coupling to the sub-wavelength detector element using a resonant near-IR antenna.
Normatividade e facticidade no recorte comunicacional da ideia de Democracia deliberativa

description: Perante a atual crise da participação pública, que assinala a necessidade de mobilização mais ativa dos cidadãos na resolução dos problemas da res publica, a democracia deliberativa emerge como uma tentativa de resposta promissora. A compreensão do seu significado à luz da Pragmática Universal põe em relevo, em primeiro lugar, o papel central da comunicação e, igualmente, a distinção dos planos normativo e fáctico da realidade comunicacional e política: planos que entre si geram permanentes tensões, a diferentes níveis de funcionamento dos processos deliberativos, como é o caso dos fóruns dos leitores na imprensa online.

Os intelectuais na Sociedade da Informação: produção cultural e participação política
Creators: name: Correia, João Carlos

description: Depois de se afirmar como uma das figuras centrais da cultura desde a Idade Média até meados do século XX, o intelectual confrontou-se com a sua dessacralização e erosão dos padrões de atividade, resultantes da emergência da cultura de massas e, mais recentemente, da sociedade em rede. Com o advento da comunicação mediática, em particular das redes sociais, a referência à razão letrada dá lugar a uma importância crescente ao ícone e ao som e torna possível um tipo de intervenção política por parte dos intelectuais, menos dependente da razão discursiva e argumentativa. Simultaneamente, as mesmas transformações fazem-se sentir ao nível do grau de autonomia crítica em relação ao sistema produtivo que era uma característica atribuída aos intelectuais. Apesar da proletarização destas camadas não ser uma realidade nova, urge saber se se mantém as condições para desempenhar essa função social crítica nas mesmas condições de autonomia e capacidade de influência que lhe foram atribuídas e que, com frequência, se traduziram numa posição social efetivamente influente.

Aspectos culturais e identitários nas músicas de intervenção Cabo-Verdiana

Year: 2013

description: Inserido nos estudos de Lusofonia, o presente trabalho pretende analisar alguns aspectos presentes na música de intervenção de Cabo Verde compostas entre 1935-1975, período em que compreende o Estado Novo em Portugal. O retrospecto da colonização portuguesa e as condições impostas às colônias nesse período resultaram na luta dos povos africanos pela independência. Com o intento de reafirmar a sua identidade, Cabo Verde, espaço escolhido para o presente estudo, revela em suas produções culturais e literárias valores que mais o caracterizam – tais como a mestiçagem e a questão linguística – elevando o que é africano e o que de fato faz parte da vida do cabo-verdiano. É importante salientar, que muitas dessas canções de protesto só chegaram ao conhecimento do público após a Revolução dos Cravos, ocorrida em abril de 1974, devido à censura imposta pelo governo salazarista. Ainda nesse período, na última fase da colonização portuguesa, por razões várias, como a fome, a seca e a falta de trabalho, o povo cabo-verdiano foi obrigado a emigrar em busca de melhores condições de vida. Com base nos dados de António Carreira (1984), Gabriel Fernandes (2002; 2006) e Leila Hernandez (2002), pretende-se discutir os principais motivos e os destinos procurados pelos ilhéus nessa fase, para que se possa, a partir dos conceitos de identidade e os aspectos históricos vividos no país nessa fase, compreender a letra e o tema das canções de intervenção contidas no CD “Música de Intervenção Cabo-Verdiana”, lançada em 1999. Pretende-se, ainda, por meio das canções Cêu di S. Tomé e Nhô Kéitone, presentes no CD em questão, mostrar como estes fatos históricos estão presentes nas manifestações culturais do povo. Ressalta-se que a música de Cabo Verde é mundialmente conhecida tornando-se um dos aspectos culturais mais valorizados do país.
