We present an elementary model of COVID-19 propagation that makes explicit the connection between testing strategies and rates of transmission and the linear growth in new cases observed in many parts of the world. An essential feature of the model is that it captures the population-level response to the infection statistics information provided by governments and other organisations. The conclusions from this model have important implications regarding benefits of wide-spread testing for the presence of the virus, something that deserves greater attention.

Ir Reflectography

AbstractInfrared (IR) reflectography has been used for many years for the detection of underdrawings on panel paintings. Advances in the fields of IR sensors and optics have impelled the wide spread use of IR reflectography by several recognized Art Museums and specialized laboratories around the World. The transparency or opacity of a painting is the result of a complex combination of the optical properties of the painting pigments and the underdrawing material, as well as the type of illumination source and the sensor characteristics. For this reason, recent researches have been directed towards the study of multispectral approaches that could provide simultaneous and complementary information of an artwork. The present work relies on non−simultaneous multispectral inspection using a set of detectors covering from the ultraviolet to the terahertz spectra. It is observed that underdrawings contrast increases with wavelength up to 1700 nm and, then, gradually decreases. In addition, it is shown that IR thermography, i.e., temperature maps or thermograms, could be used simultaneously as an alternative technique for the detection of underdrawings besides the detection of subsurface defects.

Abstract A restriction map was constructed of the ribosomal cistron in a mosquito, Aedes albopictus (Skuse). The 18s, 28s and nontranscribed spacer (NTS) regions were subcloned and used to probe for intraspecific variation. Seventeen populations were examined throughout the world range of the species. No variation was detected in the coding regions but extensive and continuous variation existed in the NTS. The NTS consisted of two nonhomologous regions. The first region contained multiple 190-bp AluI repeats nested within larger XhoI repeats of various sizes. There was a large number of length variants in the AluI repeat region of the NTS. No repeats were found in the second region and it gave rise to relatively fewer variants. An analysis of NTS diversity in individual mosquitoes indicated that most of the diversity arose at the population level. Discriminant analysis was performed on spacer types in individual mosquitoes and demonstrated that individuals within a population carried a unique set of spacers. In contrast with studies of the NTS in Drosophila populations, there seems to be little conservation of spacers in a population. The importance of molecular drive relative to drift and selection in the generation of local population differentiation is discussed.

History Of

The key problems of nation- and state-building are revealed in the concept of the chronotope of the Ukrainian “long twentieth century,” which is a hybrid projection of the “long nineteenth century.” An essential feature of this stage in the history of Ukraine and Ukrainians is the realization of the intentions of socioeconomic, ethnocultural and political emancipation: in fact, the end of the Ukrainian revolution, which began in the context of World War I and the destruction of the colonial system. The third book tells about the contradictions of post-Soviet transit. The three modern revolutions, the development of “oligarchic republics,” the subjectivization of Ukraine in the world through self-awareness of the European choice are visible manifestations of the final stage of the century-old Ukrainian revolution and anti-colonial liberation war. The essential transformations of the Ukrainian project are understood in the broad optics of post-totalitarian transit, the successful completion of which now rules for the national idea of Ukraine. For a wide audience.

Normal Sleep

The influence of the circadian clock on sleep scheduling has been studied extensively in the laboratory; however, the effects of society on sleep remain largely unquantified. We show how a smartphone app that we have developed, ENTRAIN, accurately collects data on sleep habits around the world. Through mathematical modeling and statistics, we find that social pressures weaken and/or conceal biological drives in the evening, leading individuals to delay their bedtime and shorten their sleep. A country’s average bedtime, but not average wake time, predicts sleep duration. We further show that mathematical models based on controlled laboratory experiments predict qualitative trends in sunrise, sunset, and light level; however, these effects are attenuated in the real world around bedtime. Additionally, we find that women schedule more sleep than men and that users reporting that they are typically exposed to outdoor light go to sleep earlier and sleep more than those reporting indoor light. Finally, we find that age is the primary determinant of sleep timing, and that age plays an important role in the variability of population-level sleep habits. This work better defines and personalizes “normal” sleep, produces hypotheses for future testing in the laboratory, and suggests important ways to counteract the global sleep crisis.

Offering the world countless remarkable benefits, computer mediated communication has become an essential feature of modern life. However, it has also become a medium for personal aggression and abuse of diverse kinds. The discourse of online vilification has been the topic of much research, for instance on the behaviour of trolls. This study focuses on a little researched phenomenon, the discourse of cyberbullying, in particular a subtype, cybermobbing, in which a group of participants gather online to attack an individual over a period of time. The study takes up an example of such participants who joined a Facebook group dedicated to abusing a prominent sportsman. The purpose of the study is to identify the chief discourse characteristics of cybermobbing that bind the participants together. The analysis reveals a high degree of solidarity among the participants expressed through profanity, humour, and play. The results will also throw light on the mentality of those who engage in cybermobbing.

Disability Research

In academic writing about disability, the impetus is typically used to subvert society's ableist structures and challenge misconceptions and misunderstanding around disability. However, due to the world-wide spread of COVID-19 and the restrictions put in place to reduce the virus's impact, such as asking people to wear masks in public places and the closing of universities and moving to entirely online learning, the author, who is deaf, found herself vulnerable and confronting a lack of access due to these measures. This reflexive paper will investigate how the pandemic and its effects forced the author to reconsider her ownership of her deafness. It will add to a growing body of autoethnographic disability research by contributing another facet to understandings around disability and self as they are actualized in the midst of the pandemic.

This chapter presents an account of human life primarily through Nietzsche's character of Zarathustra, who argues that human life is irreducibly diverse and thoroughly dangerous. We are constantly trying to rebuild our home within it, constantly trying to glue all the pieces of the world we live in into a whole, to order it, to turn it into “our world.” But we will never be able to remove from this world the threat of catastrophe, of destruction, of the end; we will never achieve certainty that the next step in our lives won't march us into the abyss, into which everything that has been familiar till now, everything nice and warm and orderly, vanishes. In other words, an essential feature of life as we live it is chance: the new, unexpected, alien side of life. In its every moment, life is torn open, discontinuous, fractured: diversified.

Maximus The Confessor

Maximus the Confessor in his “Ambigua” opposes himself in a decisive way to the Origenist vision of man and of his relation to God, a vision extremely wide-spread in his time. He creates his own anthropology which in its turn serves as a foundation of his theology. Man becomes a complete and integrated being and obtains his full realisation only provided that he is united with God and is a corporeal being related to the world in which he lives. Man, World and God are the terms of a dynamic relation, in which each of the first terms finds its unity. Man's unity, as well as that of the world, is realised in God, towards Whom both tend and move. The article is an attempt to retrace this movement of man, together with the world, to God, the movement crowned in unity with Him, a kind of unity that does not take away man's identity.

Children’s lived experiences of movement indicate possibilities for teaching them to be at home in increasingly challenging domains of activity. Especially significant are movements that reflect landscape connection, that carry an intention not confined to individual purpose, and that are enhanced by observational glance. The first rush of movement is described phenomenologically as an essential feature of these movements and of the vital consciousness they engender. The phenomenon of the first rush of movement attests to a mimetic impulse towards otherness that overrides personal motive and moderates an otherwise containing gaze. Its intentionality is evident in an extended, inclusive and progressive range of human movements that affirm a natural, intimate relation with others and the world at large. The embrace, caress and kiss are described as primary, elemental gestures from which movement disciplines sustaining the first rush of moment and its mimetic impulse can be cultivated. Accordingly, this study prefaces a practice of education in which children’s movements, originating in responsiveness to landscape and motivated by a mimetic impulse, can be guided towards enhanced and sustaining world relations. Vital qualities of movement can be sustained from childhood to adulthood and from the most rudimentary contacts with the world to the most refined, skill-based encounters.
