In every country except China, COVID-19 first infection cases were imported by travelers, which are either people coming back to their own country or visiting foreigners (international or external tourists). In a global and regional phenomenological analysis of COVID-19 spread, we assume that tourism inflow is a trigger mechanism of worldwide dissemination at the pandemic onset days. Taking into account all countries, a convenient common-time origin timeline was employed as if the beginning of the epidemic would have occurred simultaneously in every country. We obtained very good statistical Pearson and Spearman correlations between accumulated infected cases by country and a positive power of the product [Formula: see text], where [Formula: see text] is the tourism inflow before the pandemic and [Formula: see text] is the country population.

In the USA, COVID-19 first infection cases were imported by external travelers. At the epidemic onset days, we assume that the disease partially spreads due to domestic passengers air transportation in its densely connected airport network. Taking into account all USA states, we arranged COVID-19 infected cases data in a convenient common time origin timeline as if the beginning of the epidemic would have occurred simultaneously in every state. Looking for a trend between cases and air passengers, we obtained with this timeline very good statistical Pearson and Spearman correlations between accumulated infected cases by state and a positive power of the product [Formula: see text], where [Formula: see text] is the domestic flight passengers (travelers) inflow by state before the epidemic and [Formula: see text] is its population. We also found a good correlation between percentages of urban area by state and their COVID-19 daily new cases growth rates at onset days.

Abstract In what follows, I intend to address an issue which is at the boundaries of the phenomenological method of reflective explication, and that, in this sense, points to some limitations of the phenomenological approach to consciousness and mind. I am referring to an aporetic situation that is at the heart of the phenomenological analysis of passivity. On the one hand, phenomenology shows, at least indirectly, a passive life that is beyond the first steps of the activity of the ego in the receptive, affective life. This is something that is beyond the rising of an ego, and from which a phenomenology of the ego-form of subjective life could be addressed. On the other hand, the analytic and conceptual tools of the phenomenological method have no grips on this basic realm of subjective life. As a result, Husserl’s analysis of passivity starts with the evidence of a pre-affective, pre-egoic realm, from which a phenomenology of the ego could be developed. However, Husserl’s analyses end up with the denegation of this dimension, as if it was invisible for the phenomenological method. As a consequence, the starting point of the analysis is not passivity proper, but rather the primitive forms of receptivity, which is already a first layer of the activity of the ego. Instead of an analysis of the ego-polarization (the “birth” of the ego), the egoic layer of conscious life is simply presupposed. A phenomenology of the ego-form is, thus, at the same time promised and denied. This aporetic situation is visible in the alteration of the concept of a passive pre-givenness in Husserl’s Analysis Concerning Passive Synthesis.

The article is a review-reflection on the book by I. Kaspe In Alliance with Utopia. Semantic Frontiers of the Late Soviet Culture (Moscow: New Literary Review; 2018. 432 p.). Despite the fact that the title emphasizes the word ‘utopia’, the author prefers a broad interpretation of the ‘utopian’ concept - as a kind of conceptual context which serves as a framework that makes ‘ultimate’ meanings and values of the Soviet culture (socialism) as if ‘visible’. It may seem strange at first glance, but actually these meanings and values concentrate ‘around’ different interpretations of heroism and happiness. The article reconstructs the author’s narrative logic together with the formal structure of the book, which helps the author to prove to readers (with varying degrees of credibility) the heuristic potential of utopia as an analytical research metaphor. In particular, from the first to the final parts of the book (and the author honestly informs readers in the beginning that the book is a collection of the revised articles that were published previously, but later were adapted for the task of the historical-phenomenological analysis of the perception of utopia and combined into four thematic sections) the author develops her own concept of utopia focusing rather on different attitudes to the utopian thinking than on different interpretations of utopia in different historical periods.

We recently described an artificial substrate system which could be used to optimize labeling parameters in EM immunocytochemistry (ICC). The system utilizes blocks of glutaraldehyde polymerized bovine serum albumin (BSA) into which an antigen is incorporated by a soaking procedure. The resulting antigen impregnated blocks can then be fixed and embedded as if they are pieces of tissue and the effects of fixation, embedding and other parameters on the ability of incorporated antigen to be immunocyto-chemically labeled can then be assessed. In developing this system further, we discovered that the BSA substrate can also be dried and then sectioned for immunolabeling with or without prior chemical fixation and without exposing the antigen to embedding reagents. The effects of fixation and embedding protocols can thus be evaluated separately.
