AbstractIn 2019 the RV Meteor cruised from Guadalupe in April/May to Cape Verde in June/July and to Namibia in August/September. The distance is about 10,000 km. The ship has a moon pool for installation of instruments. In Cape Verde we had a first glimpse of the already sparsely populated moon pool. We reached Namibian waters in mid-August. In mid-September, 47 days later and 6000 km south, the ship's moon pool was sampled in the port of Walvis Bay. 13 different taxa could be identified belonging to two phyla, four classes, six orders and 10 families. Most of these species have not yet been observed in the port or in the adjacent areas and are new records for the entire Namibian coast. The goose barnacles Conchoderma auritum (Linnaeus, 1767), Conchoderma virgatum Spengler, 1789 and Lepas anatifera Linnaeus, 1758 were particularly noticeable. They were only surpassed by the large number of amphipods. The species Ericthonius brasiliensis (Dana, 1853), Jassa marmorata Holmes, 1905, Stenothoe senegalensis Krapp-Schickel, 2015 and Paracaprella pusilla Mayer, 1890 are particularly noteworthy here. In addition, the pycnogonid species Endeis straughani Clark, 1970 and the titan acorn barnacle Megabalanus coccopoma (Darwin, 1854) should be mentioned, which occurred very frequently as well. The present study shows, on the one hand, an example of the transatlantic spread of bioinvasive species by ships as vectors and, on the other hand, a convenient method for sampling ship hulls.

By the time the anticolonial war started in Guinea-Bissau, in terms of counterinsurgency doctrine Cabral could choose from two major theories. On the one hand, the theory of movement, proposed by the likes of Mao, that involved the massive participation of the peasantry. On the other, the foco theory, espoused by Che Guevara and experimented in the Cuban revolution, that consisted of the incursion in a given territory of a small group of revolutionaries with the mission to start the uprising. The revolution in Guinea is the mix between the two. It counted on the one hand with a significant adherence of the Guinean peasantry, but the party’s leadership was in the hand of a handful of cadres, most of them from Cape Verde.

In the study of article systems in creole languages, two opposing models of analysis stand out. On the one hand, Bickerton, in line with his bio-program hypothesis, proposes an article system in which there is a clearly marked distinction between the notions of specific and nonspecific reference. On the other hand, Janson explains the creole article system in terms of its transmission from the lexifier language, and its further development under the influence of the lexifier language. The capacity of these models to account for the article systems of Cape Verde and São Tomé Creole Portuguese is examined in a number of oral texts in these two languages. One feature of the analysis stands out in particular: once a discourse item has been introduced via the indefinite article, which marks it as both specific and new, no further marking of successive occurrences of that discourse item by means of a so-called definite article is necessary or even useful. This feature partially contradicts Jan-son's account and accounts for the failure of these two creoles to conform to Bickerton's universal system. Additionally, the paper considers a number of general principals governing the formation of pidgin and creole languages and the action of specific factors in their genesis.

Os Rabelados configuram comunidades rurais originárias da resistência ao poder colonial em Cabo Verde, as quais se desenvolveram parcialmente isoladas do Estado desde os anos 1940. Recentemente, no entanto, iniciativas empreendidas por mediadores culturais objetivam a inserção desses coletivos junto à sociedade envolvente, e nesses propósitos, as políticas de patrimonialização e o turismo cultural se apresentam como principais instrumentos. Partindo-se dessas realidades, o artigo aborda as complexidades que envolvem os agenciamentos referidos. Por um lado, busca-se caracterizar as formas pelas quais os agenciamentos em torno da cultura se tornaram centrais na contemporaneidade; por outra via, avalia-se os resultados mais aparentes desses empreendimentos para o caso dos Rabelados, com especial atenção em relação às problemáticas das negociações identitárias e da autenticidade.Negotiated Identities, Redefined Authenticities: Heritage Policies and Cultural Tourism Among the Rabelados of Cape Verde Abstract: The Rabelados consist of rural communities originating in the resistance to colonial power in Cape Verde, which have developed partially isolated from the state since the 1940s. Recently, however, initiatives undertaken by cultural mediators aim at the inclusion of these collectives into the surrounding society and, in these purposes, patrimonialization policies and cultural tourism are presented as main instruments. Coming from these realities, this article discusses the complexities surrounding these agencies. On the one hand, it seeks to characterize the ways in which the agencies around culture have become central in the contemporary world; on the other hand, it evaluates the most apparent results of these initiatives in the case of Rabelados, with special attention to the issues of identity negotiations and authenticity.Keywords: patrimonialization policies; cultural tourism; identities; authenticities.

The first question to be answered, in seeking coordinate systems for geodynamics, is: what is geodynamics? The answer is, of course, that geodynamics is that part of geophysics which is concerned with movements of the Earth, as opposed to geostatics which is the physics of the stationary Earth. But as far as we know, there is no stationary Earth – epur sic monere. So geodynamics is actually coextensive with geophysics, and coordinate systems suitable for the one should be suitable for the other. At the present time, there are not many coordinate systems, if any, that can be identified with a static Earth. Certainly the only coordinate of aeronomic (atmospheric) interest is the height, and this is usually either as geodynamic height or as pressure. In oceanology, the most important coordinate is depth, and this, like heights in the atmosphere, is expressed as metric depth from mean sea level, as geodynamic depth, or as pressure. Only for the earth do we find “static” systems in use, ana even here there is real question as to whether the systems are dynamic or static. So it would seem that our answer to the question, of what kind, of coordinate systems are we seeking, must be that we are looking for the same systems as are used in geophysics, and these systems are dynamic in nature already – that is, their definition involvestime.

Abstract. Two experiments examined the influence of stories on recipients’ self-perceptions. Extending prior theory and research, our focus was on assimilation effects (i.e., changes in self-perception in line with a protagonist’s traits) as well as on contrast effects (i.e., changes in self-perception in contrast to a protagonist’s traits). In Experiment 1 ( N = 113), implicit and explicit conscientiousness were assessed after participants read a story about either a diligent or a negligent student. Moderation analyses showed that highly transported participants and participants with lower counterarguing scores assimilate the depicted traits of a story protagonist, as indicated by explicit, self-reported conscientiousness ratings. Participants, who were more critical toward a story (i.e., higher counterarguing) and with a lower degree of transportation, showed contrast effects. In Experiment 2 ( N = 103), we manipulated transportation and counterarguing, but we could not identify an effect on participants’ self-ascribed level of conscientiousness. A mini meta-analysis across both experiments revealed significant positive overall associations between transportation and counterarguing on the one hand and story-consistent self-reported conscientiousness on the other hand.

SummaryThe prognosis of patients with acute myeloid leukaemia (AML) has improved considerably by introduction of aggressive consolidation chemotherapy and haematopoietic stem cell transplantation (SCT). Nevertheless, only 20-30% of patients with AML achieve long-term diseasefree survival after SCT. The most common cause of treatment failure is relapse. Additionally, mortality rates are significantly increased by therapy-related causes such as toxicity of chemotherapy and complications of SCT. Including radioimmunotherapies in the treatment of AML and myelodyplastic syndrome (MDS) allows for the achievement of a pronounced antileukaemic effect for the reduction of relapse rates on the one hand. On the other hand, no increase of acute toxicity and later complications should be induced. These effects are important for the primary reduction of tumour cells as well as for the myeloablative conditioning before SCT.This paper provides a systematic and critical review of the currently used radionuclides and immunoconjugates for the treatment of AML and MDS and summarizes the literature on primary tumour cell reductive radioimmunotherapies on the one hand and conditioning radioimmunotherapies before SCT on the other hand.

In recent years, political and social conditions have changed dramatically. Many analyses help to capture these dynamics. However, they produce political pessimism: on the one hand there is the image of regression and on the other, a direct link is made between socio-economic decline and the rise of the far-right. To counter these aspects, this article argues that current political events are to be understood less as ‘regression’ but rather as a moment of movement and the return of deep political struggles. Referring to Jacques Ranciere’s political thought, the current conditions can be captured as the ‘end of post-democracy’. This approach changes the perspective on current social dynamics in a productive way. It allows for an emphasis on movement and the recognition of the windows of opportunity for emancipatory struggles.

Political ideological pluralism, religious diversity are characteristic features of modern Ukrainian society. On the one hand, multiculturalism, socio-political, religious differentiation of the latter appear as important characteristics of its democracy, as a practical expression of freedom, on the other - as a factor that led to the deconsocialization of society, gave rise to "nodal points" of tension, confrontational processes, in particular, in political and religious spheres.

Two aspects of Schumpeter' legacy are analyzed in the article. On the one hand, he can be viewed as the custodian of the neoclassical harvest supplementing to its stock of inherited knowledge. On the other hand, the innovative character of his works is emphasized that allows to consider him a proponent of hetherodoxy. It is stressed that Schumpeter's revolutionary challenge can lead to radical changes in modern economics.

Our analysis documents that the existence of hidden “holes” in the capital of not yet failed banks - while creating intertemporal pressure on the actual level of capital - leads to changing of maturity of loans supplied rather than to contracting of their volume. Long-term loans decrease, whereas short-term loans rise - and, what is most remarkably, by approximately the same amounts. Standardly, the higher the maturity of loans the higher the credit risk and, thus, the more loan loss reserves (LLP) banks are forced to create, increasing the pressure on capital. Banks that already hide “holes” in the capital, but have not yet faced with license withdrawal, must possess strong incentives to shorten the maturity of supplied loans. On the one hand, it raises the turnovers of LLP and facilitates the flexibility of capital management; on the other hand, it allows increasing the speed of shifting of attracted deposits to loans to related parties in domestic or foreign jurisdictions. This enlarges the potential size of ex post revealed “hole” in the capital and, therefore, allows us to assume that not every loan might be viewed as a good for the economy: excessive short-term and insufficient long-term loans can produce the source for future losses.
