Abstract. As a result of technological advances in monitoring atmosphere, hydrosphere, cryosphere and biosphere, as well as in data management and processing, several databases have become freely available. These can be exploited in revisiting the global hydrological cycle with the aim, on the one hand, to better quantify it and, on the other hand, to test the established climatological hypotheses according to which the hydrological cycle should be intensifying because of global warming. By processing the information from gridded ground observations, satellite data and reanalyses, it turns out that the established hypotheses are not confirmed. Instead of monotonic trends, there appear fluctuations from intensification to deintensification, and vice versa, with deintensification prevailing in the 21st century. The water balance on land and in the sea appears to be lower than the standard figures of literature, but with greater variability on climatic timescales, which is in accordance with Hurst–Kolmogorov stochastic dynamics. The most obvious anthropogenic signal in the hydrological cycle appears to be the over-exploitation of groundwater, which has a visible effect on the rise in sea level. Melting of glaciers has an equal effect, but in this case it is not known which part is anthropogenic, as studies on polar regions attribute mass loss mostly to ice dynamics.

Educational Debate

A crítica de alguns autores quanto ao papel da escola na nova realidade educativa perante as possibilidades de interação e informação, chega a extremos. Há autores que consideram que a escola, diante dos avanços tecnológicos capazes de distribuir com eficiência a informação, perde a razão de existir (PERELMAN, 1992). Embora entenda que este seja um posicionamento reducionista e obtuso, uma vez que o papel da escola não é ou não pode ser apenas o de informar. No contexto deste artigo propomos um viés para o debate educacional para a educação no século XXI: por um lado as tecnologias digitais de comunicação e informação que abalam as estruturas centenárias da educação e por outro a autonomia que esta tecnologia possibilita contrasta com o modelo de escola e da educação oficial que temos.   PALAVRAS-CHAVE: Tecnologias digitais; autonomia, educação.     ABSTRACT The critique of some authors regarding the role of the school in the new educational reality towards the possibilities of interaction and information, reaches to extremes.

Although understands that this is a reductionist and obtuse position, since the role of the school is not or cannot be just to inform. In the context of this article we propose a bias towards the educational debate for education in the 21st century: on the one side the digital technologies of communication and information that undermine the centennial structures of education and on the other the autonomy that this technology allows contrasts with the school model and the official education we have.   KEYWORDS: Digital technologies; autonomy, education.   RESUMEN La crítica de algunos autores respecto al rol de la escuela en la nueva realidad educativa delante de las posibilidades de interacción e información, llega a extremos.

In recent years, strong concerns have been raised over the increasing numbers of disorderly protests and aggressive activism at sea. Maritime protests raise difficult – and understudied – legal questions concerning the boundaries between the legitimate application of rights of freedom of speech and assembly on the one hand, and the need to ensure safety of navigation on the other. This article examines the legal arguments in favour of maritime protest as well as national responses to it, in the context of two Polar case studies. Firstly, this article appraises the confrontational activism of the Sea Shepherd Conservation Society in its anti-whaling campaign in Antarctica, and the problematic application of anti-piracy legislation to more aggressive campaign groups. Secondly, this article examines the position in relation to oil platforms, as exemplified by the Prirazlomnaya dispute in the Arctic, as well as controversial developments in Antarctic jurisdictions. In so doing, this article argues that the protection accorded to direct action protests at sea is considerably more limited than many campaign groups might appreciate.

Abstract This essay raises the question whether citizens in the digital age can learn from how credibility is treated in international negotiations. Negotiators face problems both in attempting to send credible signals and in making credibility assessments of received signals. Several studies, starting with Schelling’s seminal analysis of commitments, indicate that credible signals are those that are somehow costly to the sender. Contributions to our understanding of how recipients make credibility assessments include Jervis’s distinction between signals (with no inherent credibility) and indices (believed to be untainted by deception). The most general conclusion emerging from existing research is that there is no definitive, infallible solution to the problem of credibility, insofar as deception and misperception are intrinsic to all signaling systems. Today’s unfortunate combination of limited awareness of credibility problems, on the one hand, and technological advances facilitating deception, on the other, calls for intensified education as well as multidisciplinary research.

ABSTRACTWithin the scope of climate change and the worldwide shift in travel patterns, the Arctic has become a highly favoured tourist destination. However, the literature on studying destination images of the northern polar regions lacks analysis of prevailing perceptions and of corresponding images held by tourists without previous travel experience. Therefore, this research, recently carried out in Germany, attempts to delineate tourists' perceptions of Greenland on the one hand and the Arctic as a whole on the other as destinations. Similarities, positive and negative differences of the cognitive and affective stages are generated and an overview of perceived dimensions and factors influencing the images are given. Although the results strongly coincide with each other, there are minor differences found in favour of Greenland. With the findings it is hoped to provide a better insight into the images held by potential visitors to the Arctic and to help those engaged in marketing Greenland as a tourist destination to identify an efficient strategy.

Selection Of

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.
