Climate change is one of the largest threats for biodiversity as changing climatic conditions often make existing habitat sites less suitable. This poses new challenges for species conservation, in particular in agricultural landscapes, where climate change may also induce modifications in agricultural land use. To conserve species in agricultural landscapes, agri-environment schemes (AES) which compensate farmers for implementing conservation measures are commonly used. However, current research on the cost-effective design of AES largely ignores necessary adaptations of conservation measures given climate change. We develop a climate-ecological-economic (CEE) model to examine how the cost-effective design of AES has to be modified under climate change. We apply the model to the conservation of eight meadow bird species in Northern Germany and determine the cost-effective conservation measures under recent and future climatic conditions. We find that the timing of conservation measures in the AES needs to be changed in the RCP8.5 scenario given the species’ phenological adaptations and the impact of extreme events (inundations) on costs. The novelty of the research lies in the development of a CEE model which considers both spatial and temporal changes in costs and benefits to develop recommendations for the cost-effective design of AES under climate change.

The collection of papers presented in this special issue addresses the non-temporal import of aspectual constructions, in conventional and less conventional contexts and expression modes. In this introduction, we outline the notions of lexical and grammatical aspect, and how they are traditionally analyzed in temporal accounts, which focus on situations’ temporal constituency, duration, and limitation in time. This serves to clarify relevant notions for those readers who are less familiar with the domain (admittedly riddled with terminological confusion) and thus explicate some of the underlying tenets of existing (temporal) accounts, which the papers in this special issue call into question. This questioning, alongside insights coming from the discussion of various non-canonical constructions/uses in different languages and from different theoretical perspectives, promises an alternative approach to aspect, which goes beyond time.

In this paper we demonstrate on the basis of diachronic and synchronic data from a variety of languages that progressives are particularly liable to be used for the expression of extravagance. We define extravagant language use as a signaling mechanism that consists in the exploitation of an unconventional construction in a given context as a way for speakers to indicate that there is something non-canonical about the situation that they are reporting. Novel constructions naturally lend themselves to such extravagant exploitation, since they are by definition to a certain extent unconventional. This is why, as we will demonstrate, the English, Dutch and French progressives were notably often recruited in extravagant contexts at the onset of their development. However, our synchronic data reveal that Present-day English, Dutch and French progressives continue to be used for extravagant purposes, which suggests that there is something inherent about progressive aspect that makes it liable to such expressive usage. This is confirmed by data from other, typologically diverse languages. We offer a cognitive-semantic analysis in terms of epistemic contingency in order to account for this intrinsic association of progressive aspect and extravagance across languages. Our analysis thus reveals that extravagance is not a transient property of emerging progressives, but that, instead, the semantics of these constructions makes them particularly liable to be recruited for extravagant purposes. It also demonstrates that in order to analyze the range of uses of progressive constructions in a unified fashion, we need to look beyond the temporal import of these constructions.

Observers of German current affairs and historians of contemporary Germany have long been cognizant of the shadow that the Nazi past and its crimes cast over postwar German history. Likewise, it has long been widely accepted as appropriate that the “old” Federal Republic would develop a political culture marked by reserve and modesty on the international stage and in its public representation—whatever seemed the opposite of the pomp, power, and ruthlessness of past German regimes. Whereas the prospect of unification in 1989-1990 still triggered concerns about the country's possible relapse into attitudes and behaviors worthy of a “fourth Reich,” two decades later, Germans were treated to the news that theirs was “the most positively viewed nation in the world.” A few years later still, German Chancellor Angela Merkel found herself widely hailed as the “leader of the free world,” a phrase soaked in Cold War connotations and hitherto reserved for the president of the United States. Merkel probably had little desire for such a click-bait label; it was the world around her that had changed on the coattails of the global ascendancy of right-wing populism and authoritarianism, resulting, for example, in the British vote to leave the European Union (“Brexit”), the presidency of Donald Trump, and the attempt of the Polish government to do away with the separation of powers. With the strong showing of the right-wing Alternative for Germany (AfD) party in the 2017 federal elections, this development had begun to affect domestic politics in Germany as well.

In this study we chart the aspectual characteristics of performative utterances in a cross-linguistic sample of sixteen languages on the basis of native-speaker elicitations. We conclude that there is not one single aspectual type (e.g., perfectives) that is systematically reserved for performative contexts. Instead, the aspectual form of performative utterances in a given language is epistemically motivated, in the sense that the language will turn to that aspectual construction which it generally selects to refer to situations that are fully and instantly identifiable as an instance of a given situation type at the time of speaking. We use the method of Multidimensional Scaling to demonstrate this: whatever the exact value of a given aspectual marker, if it is used to mark performatives, then it also commonly features in the expression of states and habits, which have the subinterval property (they can be fully verified based on a random segment), demonstrations, and other special contexts featuring more or less predictable and therefore instantly identifiable events. On the other hand, our study shows that performative contexts do not normally feature progressive aspect, which is dedicated to the expression of events that are not fully and instantly identifiable.

We report on the EPICA Dronning Maud Land (East Antarctica) deep drilling operation. Starting with the scientific questions that led to the outline of the EPICA project, we introduce the setting of sister drillings at NorthGRIP and EPICA Dome C within the European ice-coring community. The progress of the drilling operation is described within the context of three parallel, deep-drilling operations, the problems that occurred and the solutions we developed. Modified procedures are described, such as the monitoring of penetration rate via cable weight rather than motor torque, and modifications to the system (e.g. closing the openings at the lower end of the outer barrel to reduce the risk of immersing the drill in highly concentrated chip suspension). Parameters of the drilling (e.g. core-break force, cutter pitch, chips balance, liquid level, core production rate and piece number) are discussed. We also review the operational mode, particularly in the context of achieved core length and piece length, which have to be optimized for drilling efficiency and core quality respectively. We conclude with recommendations addressing the design of the chip-collection openings and strictly limiting the cable-load drop with respect to the load at the start of the run.

In this paper, we propose a unified account of the semantics of the English present progressive in the form of a semantic network, basing ourselves on the theoretical principles and analytical tools offered by the theory of Cognitive Grammar, as laid out by Langacker (1987, 1991). The core meaning of the English present progressive, we claim, is to indicate epistemic contingency in the speaker's immediate reality. It thus contrasts with the simple present, which is associated with situations that are construed as structurally belonging to reality. On the basis of a study of the Santa Barbara Corpus of spoken American English, an inventory has been made of the more specific uses of the present progressive, temporal as well as modal. It is shown that each of these uses can be derived from this basic meaning of contingency in immediate reality via a set of conceptual branching principles, in interaction with elements in the context.

Various lines of research suggest that neurotrophic processes in the hippocampus are key mechanisms in major depressive disorder and are of relevance for response to antidepressive treatment. We performed proton magnetic resonance spectroscopy (1H-MRS) of the hippocampus at 3 T in 18 unmedicated subjects with unipolar major depressive episodes and in 10 age- and gender-matched healthy volunteers. Thirteen patients underwent a second examination after 8 wk treatment with either citalopram (n=7) or nortriptyline (n=6). Of these patients, 11 MRS datasets could be used for the assessment of treatment correlates. In the cross-sectional comparison, we observed a significant reduction of the metabolic ratios Glx/Cr (Glx=glutamine, glutamate and gamma-aminobutyric acid) and glutamine (Gln)/Cr in the patient group. The Gln/Glx ratio also showed a trend towards significant reduction. The individual effect of treatment correlated with an increase in the absolute concentrations of N-acetylaspartate (NAA) and of choline compounds (Cho). Low baseline NAA and Cho levels predicted positive treatment effects. There was no difference in any clinical or metabolic measure, either at baseline or at follow-up between the two treatment groups (citalopram, nortriptyline). Our data provide first evidence for a reduction of Gln in the hippocampus of subjects with major depression. Furthermore, we provide first evidence in patients with major depression for neurorestorative effects in the hippocampus by pharmacological treatment expressed by a correlation of NAA and Cho increases with treatment response. This accounts in particular for those patients with low NAA and Cho baseline levels.
