Recent advances in technology have encouraged proposals for new approaches to ATC in Europe and elsewhere. Two such proposals, both rather loosely framed, are for ‘free flight’ or for ‘seamless contracts’; otherwise ‘tubes of flight’. These concepts, and variations on them, aim to increase the traffic capacity of the airspace. They have been the subject of numerous published papers. Given the declared objects of these systems, it is surprising that, nearly without exception, these papers discuss the proposals only in qualitative terms. The present paper discusses idealised versions of these systems on the basis of quantitative studies. It is concluded that the ‘seamless contract’ is very probably unworkable in Europe. ‘free flight’ is workable in principle, but there is a need for investigation of possible mechanisms by which last-minute problems may be resolved.

O potrzebie badań lokalnych pogranicza na przykładzie Babimojszczyzny w XX wieku

The Subject

The aim of the study is an attempt to refer to the historiography of a small microregion at the border of today's provinces: Lubuskie and Wielkopolskie, called "Babimojszczyzna". The time perspective relating to the events of World War I, Polish-German disputes, as well as the transformations in Poland and Germany after 1989 requires a new approach to historical narratives. The thesis of the article is the assumption that the hitherto historiography of this complex microregion in Polish-German relations in the first half of the 20th century did not develop new approaches. Another problem is the lack of real effects under the research models on the Polish and German narratives of the last thirty years. Their lack is particularly noticed in the context of the condition of social memory in the vicinity of Babimost, where only the tradition of the Polish Uprising 1918-1919 and the struggle for Polishness is cultivated, without a broader context. The discussed region can also be an interesting example for other similar historical areas, which, like all borderlands, were the subject of natural osmosis rather than their contact.

Recent Advances

My remarks explore the role of theory in making progress in science generally and particularly in ecology. I discuss what theory is (and isn’t). I argue that theory is a fundamentally important part of doing science efficiently, and I discuss some exciting new approaches for combining theory, data, and statistics to enhance scientific understanding. I illustrate these approaches using examples from work on foraging by mammalian herbivores.

Medical Need

Glioblastoma (GBM) is the most lethal form of brain tumor and remains a large, unmet medical need. This review focuses on recent advances in the neurosciences that converge with the broader field of immuno-oncology. Recent findings in neuroanatomy provide a basis for new approaches of cellular therapies for tumors that involve the CNS. The ultimate success of immunotherapy in the CNS will require improved imaging technologies and methods for analysis of the tumor microenvironment in patients with GBM. It is likely that combinatorial approaches with targeted immunotherapies will be required to exploit the vulnerabilities of GBM and other brain tumors.

Platelet Transfusions

Abstract The demand for platelet transfusions continues to grow. Several complementary approaches that may help meet this demand in the future are reviewed. First, platelet bacterial testing is beginning to allow the extension of platelet storage beyond 5 days. Studies are also underway aimed at better preserving viability and function during ex vivo platelet storage: additive solutions and other approaches are being developed to try to negate the “platelet storage lesion.” Finally, new approaches to dosing platelets may help extend the limited supply.

In the last few decades, the importance of selenium in human health has been the subject of numerous studies. It is believed that the physiological effects of selenium occur mainly through the function of selenoproteins, which incorporate selenium in the form of one or more selenocysteine residues. Recent advances in understanding the complex regulation of selenoprotein synthesis and functional characterization of several members of the selenoprotein family have contributed to an improved comprehension of the role(s) of selenium in human health and the great diversity of physiological pathways influenced by this trace element.

AbstractI wondered at first why I had been asked to perform the task of commenting on the scientific discussion of this meeting, until a member of the Scientific Organising Committee pointed out to me that I have not published a serious paper on the subject of the colloquium in his memory (I am not sure whether this is more a statement of the seriousness of my publications, of my publication frequency or of the duration of Jørgen’s memory); however, I am presumably considered to be unbiased by recent advances. Nevertheless, the time allotted (for the oral address) and the corresponding space (in these published proceedings) are inadequate for a complete and balanced review – in any case, that is hardly either desirable or necessary, since the discussions are all still fresh in our minds – and therefore I have been freed to comment personally on some selected issues that have captured my interest.

The Subject

The term post-hypnotic suggestion (P.H.S.) will be used in this paper as meaning the form of words which constitute the suggestion, while by the term post-hypnotic effect (P.H.E.), will be meant the behaviour of the subject consequent on the P.H.S. Quantitative studies of post-hypnotic behaviour using slowing of reaction time (RT) as the P.H.E. have already been described in relation to the duration of P.H.E. (Edwards, 1963), and the influence of amnesia on P.H.E. (Edwards, 1965). The aim of the present study was to investigate the influence on P.H.E. of giving a signal similar to but not identical with the signal defined in the P.H.S. as that which would evoke the P.H.E.
