The Farol Deposit (Depósito do Farol) – a Pleistocene beach deposit from Cape Mondego (Figueira da Foz, West Central Portugal)*

Among the Pleistocene and Holocene units recorded near the marine cliffs of Cape Mondego (Figueira da Foz, West Central Portugal) stands out the Farol Deposit (Depósito do Farol), at an altitude of ±95 m above present sea level. It is a marine terrace with three exposures of interstratified conglomerates and sands, overlapped by calclititic-fanglomerates. This sedimentary setting indicates that deposition took place in a seashore environment influenced by the proximity of a marine palaeocliff. The deposit has an interesting subfossil fauna with abraded and fragmented shells of Nucella lapillus (LINNÉ, 1758), Patella vulgata (LINNÉ, 1758) and Littorina littorea (LINNÉ, 1758), suggesting the existence of an environment with colder surface seawater, when compared with the present day Portuguese seashore. These specimens belonged to marine communities adapted to live in intertidal rocky platforms, which have been exposed to the cyclic action of waves and tidal flows, on the swash and surf zones. The Farol Deposit can be related to an Early/Middle Pleistocene “cold-water” episode, earlier to the Isotopic Stages 7 and 11. This episode occurred before the deposition of the units Quiaios Sands (Areias de Quiaios) and Cantanhede Sands (Areias de Cantanhede) (Sicilian?), but later than the Arazede Sands (Areias de Arazede) and Marinha das Ondas Sands (Areias de Marinha das Ondas) (Early Pleistocene).

Litostratigrafia do Terciario da região Miranda do Corvo-Viseu (Bacia do Mondego, Portugal)

The lithostratigraphic units (2 groups, 5 formations and 4 members) of the Tertiary of the Miranda do Corvo-Viseu region (Central Portugal) are here described. For each unit the characterization and description (boundaries, diagnostic properties and atributes) were included. The stratigraphic, lithological, sequential and tectonic data allow correlations with other units of the same Tertiary basin located more to west and support the chronostratigraphic attribution. Sedimentologic characteristics of the deposits lead to the interpretation of the influence of tectonism, climate and eustasy during the sedimentary evolution of this Basin.

Variação dos parâmetros paleomagnéticos em perfis dos Tufos de Condeixa (Baixo Mondego, Portugal)

Paleomagnetic parameters measured in 4 outcrops of the Tufos de Condeixa are presented. The directional signatures allow the admission of the Reversed Polarity Criptchron C1n-1 in the Condeixa-a-Velha outcrop. It was possible to discuss the magnetic properties, origin of the magnetic grains and paleoclimatic variation relationships. The downward of the initial magnetization and magnetic susceplibility values in the Condeixa-a-Velha outcrop coincide with the Cln-1 (504-493 Ka) occurrence and may represent a paleoclimatic variation. The Tufos de Condeixa were formed during the Ionian-Tarentian(?).

Cape Verde’s foreign policy: an economic perspective

The virtuous cycle between development success and foreign policy in Cape Verde reflects a positive interaction between globalization and governance. Development success under globalization entails positive market perceptions regarding the orientation and predictability of policies as well as the accompanying institutional arrangements, thereby making foreign policy salient beyond the comparator group, or “aspirational”. Even if there is no universally applicable development model, an aspirational foreign policy can be built on positive rankings with respect to comparator groups. In Macedo and Pereira (2010), macrolevel policy and institutional combinations underpinning trade diversification and income convergence in West and Southern Africa are used to establish development success for Cape Verde and Mozambique respectively. Here, the narrative of long-term development helps identify the following drivers: moving towards a market economy; opening up to regional and global trade; increasing economic and political freedom; pursuing macroeconomic stability and financial reputation; ensuring policy continuity (especially in trade and industrial sectors) and focusing on human development (especially poverty reduction and education). Looking at GDP per capita and indicators of financial reputation and good governance of sub-regional peers is not sufficient to conclude that Cape Verde’s convergence will be sustained. Nevertheless, the positive interaction between trade and financial globalization, on the one hand, and democracy and good governance, on the other, have positive implications for the effectiveness of foreign policy across the region as well as in the Portuguese-speaking community.

Productivity gains from migration: An analysis of Cape Verdean return migrants

Are return migrants more productive than non-migrants? If so, is it a causal effect or simply self-selection? Existing literature has not reached a consensus on the role of return migration for origin countries. To answer these research questions, an empirical analysis was performed based on household data collected in Cape Verde. One of the most common identification problems in the migration literature is the presence of migrant self-selection. In order to disentangle potential selection bias, we use instrumental variable estimation using variation provided by unemployment rates in migrant destination countries, which is compared with OLS and Nearest Neighbor Matching (NNM) methods. The results using the instrumental variable approach provide evidence of labour income gains due to return migration, while OLS underestimates the coefficient of interest. This bias points towards negative self-selection of return migrants on unobserved characteristics, although the different estimates cannot be distinguished statistically. Interestingly, migration duration and occupational changes after migration do not seem to influence post-migration income. There is weak evidence that return migrants from the United States have higher income gains caused by migration than the ones who returned from Portugal.

Wealth Management in Africa: The Cape Verde Opportunity

This work project consists of a comprehensive study of the possibility of opening a Wealth Management (WM) firm located in Cape Verde (CV), and was made at the request of NovoBanco’s Research Sectorial team. WM is a growing industry that consists in the set of financial services provided to wealthy clients. After taking into account the expected industry growth of the Sub-Saharan region, the preferences of the African wealthy, the current industry structure, and the advantages and disadvantages of locating a WM business in CV, it is concluded that a business opportunity exists. The reasons for thus, along with relevant recommendations, including which services a new business should offer and whom to target specifically, are presented in the final section.

Análise computacional da evolução da hidromorfologia do Baixo Mondego em resultado da subida do nível do mar

O êxito na previsão das consequências da subida do nível do mar à escala global está dependente de uma correcta análise de todos fenómenos que daí poderão resultar. Neste âmbito, o presente estudo incide sobre o efeito da subida do nível do mar na hidromorfologia de rios, parâmetro que não é com frequência um dado de entrada nas simulações numéricas em estudos e projectos de Hidráulica Fluvial. Desenvolveu-se um modelo computacional na linguagem de programação Fortran (FTN 95), que permite simular a longo prazo a evolução do fundo móvel e da superfície livre de um rio. É um modelo de dinâmica sedimentar, unidimensional, que simula escoamentos em regime quase-permanente e em canais de topografia simples, utilizando a fórmula de Engelund-Hansen para o transporte sólido. O modelo foi aplicado no trecho mais a jusante do Mondego, desde Coimbra até à foz no Atlântico, onde o rio flui na zona do chamado Baixo Mondego, planície aluvial, alvo de grandes alterações antropogénicas, nomeadamente obras de regularização fluvial. As que foram realizadas no séc. XVIII modificaram o original percurso do rio atribuindo-lhe uma topografia simples, mas não resolveram o seu principal problema, o excesso de assoreamento a jusante de Coimbra, tendo como consequência frequentes inundações e cheias. Estas obras colocaram em evidência a grande vulnerabilidade do rio aos problemas de transporte sólido e assoreamento. Mais tarde, em finais do séc. XX, as obras realizadas na sequência do Plano de Aproveitamento do Baixo Mondego vieram, de uma forma integrada, contribuir para o seu equilíbrio hidromorfológico. Actualmente, face à subida do nível do mar volta a colocar-se a questão do assoreamento a jusante de Coimbra. Logo, é importante conhecer as previsões a longo prazo de dinâmica sedimentar deste troço, para a sua adequada gestão. Foram realizadas previsões para 20 cenários num horizonte temporal de 100 anos, todos eles consideram o caudal dominante calculado para o rio e variam de acordo com a subida do nível do mar, o caudal sólido e diâmetro médio dos sedimentos. Os resultados obtidos foram os previstos qualitativamente, isto é, a subida do nível do mar poderá alterar o leito aluvionar, elevando as cotas de fundo e aumentando os volumes de assoreamento.

Vila Galé hotels' internationalization to Cape Verde

The intent of this paper is to assess the most suitable internationalization strategy for Vila Galé Hotels into the Cape Verdean market (namely into Sal Island), under an investment on a 5-star resort with an all-inclusive system. First, the company’s historic moves onto opening new business units, its corporate strategy triangle and its brand communication channels were studied. Afterwards, the macroeconomics, the hotel industry and other relevant trends of the country at stake were analysed in order to understand the best positioning for Vila Galé in the market as well as the most fitting plan for the project. Finally, it was shown that building a 5-star resort is the most appropriate mode of entry into this market. Keywords:

Dinossáurios Eocretácicos de Lagosteiros

According to an ancient folkloric legend, Our Lady, stepping down from the sea, would have rided on a mule to the platform above the cliffs named Pedra da Mua at Lagosteiros'bay, near Espichel cape. Mule's footprints, regarded by fishermen as evidence, would be clearly recognizable on exposed surfaces of the rocks. Indeed there are footprints but from Dinosaurs of latest Jurassic, Portlandian age, this spectacular locality being specially rich in giant Sauropod tracks (that have seldom been found elsewhere in Europe). As we proceeded to its study, another locality with Dinosaur footprints, Lower Cretaceous (Hauterivian) in age, was found on the northern cliffs at Lagosteiros. It is probably the richest one in european Lower Cretaceous and the only of this age known in Portugal, so we decided to give priority to its study. Dinosaur tracks have been printed on calciclastic sands in a lagoonal environment protected by fringing coral reefs. There have been emersion episodes; beaches were frequented by Dinosaurs. Later on, the marine barremian ingression restablished a gulf and such animals could not come here any more. Under a paleogeographical viewpoint, the evidence of a marine regression near the end of Hauterivian is to be remarked. Five types of tracks and footprints have been recognized: - Neosauropus lagosteirensis, new morphogenus and species, tracks from a giant Sauropod, perhaps from Camarasaurus; with its proportions the total length of the author would be about 15,5 m. These are the only Sauropod tracks known till now in Europe's Lower Cretaceous. - tracks from a not so big quadruped, maybe a Sauropod (young individual?); however it is not impossible that they were produced by Stegosaurians or Ankylosaurians. -Megalosauropus (?Eutynichnium) gomesi new morphospecies, four Theropod tracks most probably produced by megalosaurs. - Iguanodon sp., represented by some footprints and specially by a set corresponding to the feet and tail from an individual standing in a rest position. - problematical, quite small-sized biped (maybe an Ornithopod related to Camptosaurus). Evidence points to a richer fauna than that known in barremian "Dinosaur sandstones" from a nearby locality, Boca do Chapim. Lagosteiros' association clearly indicates the predominance of herbivores, which required large amounts of vegetable food in the neighbourhood. This is an indirect evidence of the vegetal wealth, also suggested by associations of plant macrofossils, polen and spores found in early Cretaceous sediments at the same region. The relatively high proportion of Theropoda is related to the wealth of the whole fauna, which comprised a lot of the prey needed by such powerful flesh-eaters. The evidence, as a whole, points out to a warm and moist climate. All the tracks whose direction could be measured are directed to the southern quadrants, this being confirmed by the approximative direction of other footprints. Massive displacements (migration?) could take place during a brief emersion episode. This may result from the ingression of barremian seas, flooding the region and restablishing here a small gulf. Even if the arrival of the waters damaged certain footprints it has not destroyed them completely, thus allowing the preservation of such evidence from a remote past.

Faunes ichthyologiques du Néogène Supérieur d’Angola, leur âge, remarques sur le Pliocène marin en Afrique Australe

This note is concerned with fish remains from Upper Neogene beds at Farol das Lagostas (and nearby quarry of SECIL) and Baía Farta, mainly recovered by the author in 1960, 1961, 1963 and 1967. For further data see ANTUNES, 1964, pp. 213-215. All the forms identified until now (many of them for the first time) are show in «tableau I». Smaller ones are poorly represented. I. benedeni is provisorily accepted as a distinct species, though it may correspond to a dental morphotype that does exist equally in the extant I. oxyrhinchus (see text): therefore I. benedeni from Farol das Lagostas may after all represent only some dental variations that really belong in the form described as I. cf. oxyrhinchus. The presence of Aprionodon and Hypoprion could not be ascertained: Procarcharodon megalodon, Carcharodon carcharias, Isurus benedeni. Galeocerdo cuvieri, and Carcharhinus sp. I and sp. II are specially discussed. The whole fauna does not correspond either to a very shallow and coastal environment, or to deep waters far away from the coast. It clearly points out to warm waters: an acceptable model would be the fauna from the tropical Atlantic between Northern Angola and Senegal-Cape Verde. The age of this fauna was long regarded as Burdigalian. The data formerly presented (ANTUNES, 1963) that allowed us to ascribe a pliocene age to the uppermost Neogene beds of Farol das Lagostas (Neogene III, ANTUNES, 1964) are reviewed and developed in this paper. This view is corroborated by planctonic foraminifera and stratigraphical data which provide further evidence to prove the presence of miocene beds much younger than Burdigalian, and that some deposits previously correlated to this stage have instead a Plio-Pleistocene age. Fish fauna from Farol das Lagostas is very characteristic, with giant P. megalodon in association with C. carcharias (which predominates, and whose stratigraphical distribution is particularly discussed), and with other very advanced forms like the extant tiger shark, G. cuvieri, enormous I. Benedeni, Hemipristis, and Carcharhinus (whose size largely exceeds the maximum observed with miocene material). With the exception of P. megalodon (extinct) all the other forms show very close affinities, or even identity with modern species. Comparisons with very similar faunas from some South African localities that may also have a Pliocene age are also presented.
