Representation of the “Quality” Category in the Advertising Text of the Turn of the 20th Century (Based on Ural Press)

This article considers the features of the representation of the category of “quality” in advertising texts at the turn of the twentieth century. The author refers to daily and weekly regional periodicals of the time: Ural’skaia Zhizn’, Ural’skij Listok, Ekaterinburgskaia Nedelia, Delovoi Korrespondent, and Ekaterinburgskaia Gazeta selectively reviewing issues from 1893 to 1917. Although it does not itself produce ideas and meanings as it only applies them for its own needs, advertising as a source is interesting primarily because it reflects the basic values and fashion trends of its era. The aim of the study is to analyze the possible ways of communicating about the quality of the product in a holistic way. In the course of the work, the author identifies 8 tactics for informing the potential buyer about the quality of goods, and several related categories, such as “authenticity”, “authority”, and “status”. The research focuses on the peculiarities of the language design of information about the quality, as well as the analysis of the reasons for the choice by the authors of the advertising of a particular way of presenting this information. Much attention is also paid to the general characteristics of the development of an advertising text at the turn of the twentieth century. An analysis of the tactics of informing the buyer about the quality of the goods also helps draw an approximate “portrait” of the recipient of the advertisement — from rational people, for whom practicality and utility come first, to those who are ready to succumb to manipulation and persuasion choosing a product

Phenological shifts of abiotic events, producers and consumers across a continent

Ongoing climate change can shift organism phenology in ways that vary depending on species, habitats and climate factors studied. To probe for large-scale patterns in associated phenological change, we use 70,709 observations from six decades of systematic monitoring across the former Union of Soviet Socialist Republics. Among 110 phenological events related to plants, birds, insects, amphibians and fungi, we find a mosaic of change, defying simple predictions of earlier springs, later autumns and stronger changes at higher latitudes and elevations. Site mean temperature emerged as a strong predictor of local phenology, but the magnitude and direction of change varied with trophic level and the relative timing of an event. Beyond temperature-associated variation, we uncover high variation among both sites and years, with some sites being characterized by disproportionately long seasons and others by short ones. Our findings emphasize concerns regarding ecosystem integrity and highlight the difficulty of predicting climate change outcomes. The authors use systematic monitoring across the former USSR to investigate phenological changes across taxa. The long-term mean temperature of a site emerged as a strong predictor of phenological change, with further imprints of trophic level, event timing, site, year and biotic interactions.Peer reviewe

Chronicles of nature calendar, a long-term and large-scale multitaxon database on phenology

We present an extensive, large-scale, long-term and multitaxon database on phenological and climatic variation, involving 506,186 observation dates acquired in 471 localities in Russian Federation, Ukraine, Uzbekistan, Belarus and Kyrgyzstan. The data cover the period 1890-2018, with 96% of the data being from 1960 onwards. The database is rich in plants, birds and climatic events, but also includes insects, amphibians, reptiles and fungi. The database includes multiple events per species, such as the onset days of leaf unfolding and leaf fall for plants, and the days for first spring and last autumn occurrences for birds. The data were acquired using standardized methods by permanent staff of national parks and nature reserves (87% of the data) and members of a phenological observation network (13% of the data). The database is valuable for exploring how species respond in their phenology to climate change. Large-scale analyses of spatial variation in phenological response can help to better predict the consequences of species and community responses to climate change.Peer reviewe

Dynamic Blockage in Indoor Reflection-Aided Sub-Terahertz Wireless Communications

The sixth-generation cellular systems are expected to utilize the text sub-terahertz frequency band covering 100–300-GHz. Due to high path losses, the coverage of such systems will be limited to a few tens of meters making them suitable for indoor environments. As compared to outdoor deployments, indoor usage of text sub-terahertz systems is characterized by the need to operate over shorter distances using both line-of-sight (LoS) and text in-reflection propagation paths. This potentially results not only in the attenuation of radio signal, but in the appearance of diffraction signatures in its text time-related metrics too. We conduct a detailed measurement campaign at the carrier frequency of 156 GHz and report on the dynamics of the reflection and blockage losses as well as signal fall, blockage, and recovery times over various in-reflection paths. We also develop reflection model and use it to extract the complex permittivities of glass, drywall and aerated concrete from their measured reflection spectra. The extracted permittivities of $7.23+0.22i$ , $2.63+0.026i$ , $1.9+0.017i$ are consistent with the text material-dependent reflection losses, which are as high as 16 dB for transverse electric (TE)-polarized and 39 dB for transverse magnetic (TM)-polarized signals. Moreover, the asymmetry in the side lobe levels of the transmitting and receiving antenna beams results in the additional losses ranging from 16 to 49 dB as measured for 3.55–4.3-m long text non-specular paths with the angles of departure and reception within $30-70^{\circ }$ . The blockage losses, in turn, are in the range of 6–17 dB. We observe that the presence of a text re-directing material does not affect their mean value. However, the acquired blockage duration, signal fall and recovery times are noticeably smaller than in the LoS channels with the same directivity. This implies that the text time-budget for blockage detection is much smaller: it reduces to just 20–40 ms as compared to 80–100 ms intrinsic to the LoS propagation paths

Differences in spatial versus temporal reaction norms for spring and autumn phenological events

For species to stay temporally tuned to their environment, they use cues such as the accumulation of degree-days. The relationships between the timing of a phenological event in a population and its environmental cue can be described by a population-level reaction norm. Variation in reaction norms along environmental gradients may either intensify the environmental effects on timing (cogradient variation) or attenuate the effects (countergradient variation). To resolve spatial and seasonal variation in species' response, we use a unique dataset of 91 taxa and 178 phenological events observed across a network of 472 monitoring sites, spread across the nations of the former Soviet Union. We show that compared to local rates of advancement of phenological events with the advancement of temperature-related cues (i.e., variation within site over years), spatial variation in reaction norms tend to accentuate responses in spring (cogradient variation) and attenuate them in autumn (countergradient variation). As a result, among-population variation in the timing of events is greater in spring and less in autumn than if all populations followed the same reaction norm regardless of location. Despite such signs of local adaptation, overall phenotypic plasticity was not sufficient for phenological events to keep exact pace with their cues-the earlier the year, the more did the timing of the phenological event lag behind the timing of the cue. Overall, these patterns suggest that differences in the spatial versus temporal reaction norms will affect species' response to climate change in opposite ways in spring and autumn
