Zaliznjak & Mikaèljan 2014 is a critique of the model of Russian aspect found in Janda 2012 and Janda et al. 2013. In this rebuttal I give a brief overview of my model of Russian aspect and then address the criticisms made by Zaliznjak & Mikaèljan. I begin by examining the four assumptions stated by Zaliznjak & Mikaèljan, which I find to be unnecessary and lacking in theoretical gounding. Their assumption that aspectual correlation is uniformly directed from perfective to imperfective is particularly problematic. I compare Zaliznjak & Mikaèljan’s assumption with the single assumption my work is based on, namely that linguistic cognition is not fundamentally different from general cognition, and present the entailments of this assumption and what they mean for an investigation of Russian aspect. I then present four further problems with Zaliznjak & Mikaèljan’s model of Russian aspect: the alleged transfer of meaning from perfective to imperfective, the criteria for identifying prototypical prefixed perfectives, their claim that overlap and emptiness can be equated, and their postulation of deprefixation.Zaliznjak & Mikaèljan 2014 is a critique of the model of Russian aspect found in Janda 2012 and Janda et al. 2013.

Outcome in patients perceived as receiving excessive care across different ethical climates: a prospective study in 68 intensive care units in Europe and the USA
Purpose: Whether the quality of the ethical climate in the intensive care unit (ICU) improves the identification of patients receiving excessive care and affects patient outcomes is unknown. Methods: In this prospective observational study, perceptions of excessive care (PECs) by clinicians working in 68 ICUs in Europe and the USA were collected daily during a 28-day period. The quality of the ethical climate in the ICUs was assessed via a validated questionnaire. We compared the combined endpoint (death, not at home or poor quality of life at 1 year) of patients with PECs and the time from PECs until written treatment-limitation decisions (TLDs) and death across the four climates defined via cluster analysis. Results: Of the 4747 eligible clinicians, 2992 (63%) evaluated the ethical climate in their ICU. Of the 321 and 623 patients not admitted for monitoring only in ICUs with a good (n = 12, 18%) and poor (n = 24, 35%) climate, 36 (11%) and 74 (12%), respectively were identified with PECs by at least two clinicians. Of the 35 and 71 identified patients with an available combined endpoint, 100% (95% CI 90.0–1.00) and 85.9% (75.4–92.0) (P = 0.02) attained that endpoint. The risk of death (HR 1.88, 95% CI 1.20–2.92) or receiving a written TLD (HR 2.32, CI 1.11–4.85) in patients with PECs by at least two clinicians was higher in ICUs with a good climate than in those with a poor one. The differences between ICUs with an average climate, with (n = 12, 18%) or without (n = 20, 29%) nursing involvement at the end of life, and ICUs with a poor climate were less obvious but still in favour of the former. Conclusion: Enhancing the quality of the ethical climate in the ICU may improve both the identification of patients receiving excessive care and the decision-making process at the end of life

Early-Warning Signals of Individual Tree Mortality Based on Annual Radial Growth
Tree mortality is a key driver of forest dynamics and its occurrence is projected to increase in the future due to climate change. Despite recent advances in our understanding of the physiological mechanisms leading to death, we still lack robust indicators of mortality risk that could be applied at the individual tree scale. Here, we build on a previous contribution exploring the differences in growth level between trees that died and survived a given mortality event to assess whether changes in temporal autocorrelation, variance, and synchrony in time-series of annual radial growth data can be used as early warning signals of mortality risk. Taking advantage of a unique global ring-width database of 3065 dead trees and 4389 living trees growing together at 198 sites (belonging to 36 gymnosperm and angiosperm species), we analyzed temporal changes in autocorrelation, variance, and synchrony before tree death (diachronic analysis), and also compared these metrics between trees that died and trees that survived a given mortality event (synchronic analysis). Changes in autocorrelation were a poor indicator of mortality risk. However, we found a gradual increase in inter- annual growth variability and a decrease in growth synchrony in the last similar to 20 years before mortality of gymnosperms, irrespective of the cause of mortality. These changes could be associated with drought-induced alterations in carbon economy and allocation patterns. In angiosperms, we did not find any consistent changes in any metric. Such lack of any signal might be explained by the relatively high capacity of angiosperms to recover after a stress-induced growth decline. Our analysis provides a robust method for estimating early-warning signals of tree mortality based on annual growth data. In addition to the frequently reported decrease in growth rates, an increase in inter-annual growth variability and a decrease in growth synchrony may be powerful predictors of gymnosperm mortality risk, but not necessarily so for angiosperms.Peer reviewe

Russian word-formation in contrast with Czech and Norwegian
Although some scholarship on metonymy has mentioned examples of word-formation and some scholarship on word-formation has mentioned the presence of metonymy, to date there has been no attempt to examine the systematic role of metonymy in the domain of word-formation. This article presents an empirical study of the metonymies signalled by derivational suffixes in Russian, Czech and Norwegian. This approach facilitates cross-linguistic comparison that reveals significant differences among languages, and these differences appear relevant to cultural differences
