AbstractThis paper examines the factors affecting U.S. industry employment change in the early months of the COVID-19 pandemic. Results show that the percentage of industry employment in occupations that require close physical proximity has a negative effect on year-over-year employment change in the six months of April through September of 2020. On the other hand, the percentage of industry employment in jobs that involve high interaction with the public has a negative effect on year-over-year employment change in April and May, but not in the months of June to September. These different results related to physical proximity and interaction with the public are driven, in part, by the uneven impacts of COVID-19 on hospitality and retail businesses.

Geopolymers are created by mixing a source of aluminosilicates, which can be natural or by-products from other industries, with an alkaline solution. These materials based on by-products from other industries have proven to be a less polluting alternative for concrete production than ordinary Portland cement (OPC). Geopolymers offer many advantages over OPC, such as excellent mechanical strength, increased durability, thermal resistance, and excellent stability in acidic and alkaline environments. Within these properties, mechanical strength, more specifically compressive strength, is the most important property for analyzing geopolymers as a construction material. For this reason, this study compiled information on the different variables that affect the compressive strength of geopolymers, such as Si/Al ratio, curing temperature and time, type and concentration of alkaline activator, water content, and the effect of impurities. From the information collected, it can be mentioned that geopolymers with Si/Al ratios between 1.5 and 2.0 obtained the highest compressive strengths for the different cases. On the other hand, high moderate temperatures (between 80 and 90 °C) induced higher compressive strengths in geopolymers, because the temperature favors the geopolymerization process. Moreover, longer curing times helped to obtain higher compressive strengths for all the cases analyzed. Furthermore, it was found that the most common practice is the use of sodium hydroxide combined with sodium silicate to obtain geopolymers with good mechanical strength, where the optimum SS/NaOH ratio depends on the source of aluminosilicates to be used. Generally speaking, it was observed that higher water contents lead to a decrease in compressive strength. The presence of calcium was found to be favorable in controlled proportions as it increases the compressive strength of geopolymers, on the other hand, impurities such as heavy metals have a negative effect on the compressive strength of geopolymers.

<p>This paper aims at an analysis of legal effects of failures occurring to technical devices and ICT networks which are used for submitting electronic applications to administrative authorities within general administrative proceedings in form of e-submissions as well as legal effects of errors in data transmission in connection with the process of sending such submissions. Problems emerging in such situations make a very interesting yet not fully studied issue. So far no written analyses have been issued and the single cases that happen are resolved by administrative courts on an <em>ad causam</em> basis. Despite the fact that the administrative proceedings digitalization process has been going on for over 20 years, its importance has actually been confirmed now, during the COVID-19 pandemic, partially due to the necessity of meeting the sanitary measures, avoiding gatherings, limited or suspended operations of the public institutions on site which makes the electronic communication between the participants of administrative proceedings “attractive”. For this reason, electronic administrative proceedings have become an attractive solution in this difficult and unpredictable period. The authors formulated here a hypothesis that malfunctions of technical devices or ICT networks used for submitting applications or motions may result even in failure to submit the said applications. In some cases, however, it is possible to eliminate such a negative effect by applying Article 58 of the Administrative Proceedings Code. On the other hand, an error in data transmission of an application consolidated in the electronic form depending on the nature of the error and the stage of the proceeding where such error has been noted may be – in the authors’ opinion – as a rule, deemed a formal failing. Article 64 § 2 of the Administrative Proceedings Code refers to the indicated cases.</p>

In the last few years, it has often been said that the current fashion system is outdated, still operating by a twentieth-century model that celebrates the individualism of the 'star designer'. In I- D, Sarah Mower recently stated that for the last twenty years, fashion has been at a cocktail party and has completely lost any connection with the public and daily life. On the one hand, designers and big brands experience the enormous pressure to produce new collections at an ever higher pace, leaving less room for reflection, contemplation, and innovation. On the other hand, there is the continuous race to produce at even lower costs and implement more rapid life cycles, resulting in disastrous consequences for society and the environment.

Myriophyllum aquaticum (Vell.) Verdc. produces two morphologically different forms of leaves based on whether they are aerial or aquatic. The objective of this study was to determine whether there are any similarities or differences between these two growth forms during their early stages of development. A comparative developmental study of aerial and aquatic growth forms of M. aquaticum was conducted from a qualitative and quantitative perspective using a scanning electron microscope. The pattern of leaf and lobe initiation such as their origin and shape were similar in both growth forms until the fourth plastochron (stage P4). Differences between the two growth forms became evident from stage P5 onward, where a larger shoot apical meristem (SAM), elongated epidermal cells, shorter and slightly more numerous lobes, as well as the presence of appendage-like structures characterized aquatic growth forms. On the other hand, aerial growth forms had smaller SAM, bulb-like epidermal cells, and longer and slightly less numerous leaf lobes. Significant differences between growth forms were noted for parameters such as volume of SAM, length of terminal, first, and middle lobes, as well as the length from first to last lobes. The volume of the SAM of aquatic shoot tips was always greater than aerial forms. On the other hand, lobes of aerial forms were always longer than the aquatic counterpart during early stages of development. This study on the development of M. aquaticum shows that the aerial and aquatic growth forms diverge from their early stages of development.

Climatologists have recently introduced a distinction between projections as scenario-based model results on the one hand and predictions on the other hand. The interpretation and usage of both terms is, however, not univocal. It is stated that the ambiguities of the interpretations may cause problems in the communication of climate science within the scientific community and to the public realm. This paper suggests an account of scenarios as props in games of make-belive. With this account, we explain the difference between projections that should be make-believed and other model results that should be believed.

Abstract We know that Helmuth Plessner complained about his anthropological magnum opus, published in 1928, being overshadowed by Heidegger from the beginning. When the latter, in turn, responded to Plessner, for example to his preface to Stufen, it was always anonymously; Heidegger never actually mentioned Plessner in any publication. Plessner on the other hand emphasized that he had developed his concept without any knowledge of Sein und Zeit, even though since 1924, he had shown strong interest in the yet-unknown colleague’s work. Thus, it appeared to the public that they philosophised independently of one another. In fact, the situation is much more complicated. This paper tries, above all, to identify the sources of the peculiar discomfort caused on both sides by the work of the respective other, as well as to delineate the philosophical effects. Notably in Heidegger’s case, not enough is known about this. Heidegger starts out, in the 1920’s, cultivating a strong anti-anthropological affect; however, after his triumphal success, both with his publication and in the institutional field, in 1927/1928, he finds himself in an orientation crisis; it is from this point onwards that traces of Plessner’s anthropology can be found in his thinking. Ultimately, Plessner will prove a serious source of irritation as well as of inspiration for Heidegger. Additionally, from a systematic point of view, the present text retraces the main points of Plessner’s critique (subjectivity, disembodiedness of fundamental ontology). The investigation makes use of a broader corpus of text than was available to Plessner and Heidegger’s contemporaries, and concentrates on two questions: Did Plessner understand his opponent? Is he able to raise valid objections? It becomes obvious that Plessner is right in complaining about disembodiedness (even though his own Leib philosophy remains conceptually diffuse), while some differentiation is advisable concerning the subjectivism charge.

This article compares the language ideologies of language experts (both academic and non-academic) in online news media in Lithuania, Norway and Serbia. The results will reveal that language is understood in diametrically opposed ways amongst Lithuanian and Serbian academic experts on the one, and Norwegian academic experts on the other hand. Lithuanian and Serbian academic experts are influenced by modernist ideas of language as a single, homogenous entity, whose borders ideally match the borders of an ethnic group. Norwegian academic experts function in the public sphere as those who try to deconstruct the modernist notion of language by employing an understanding of language as a cognitive tool that performs communicative and other functions. On the other hand, non-academic experts in all the three countries exhibit a striking similarity in their language ideologies, as the great majority expresses modernist ideals of language.

Pollution  represents  a  problem  common  to economy and  public  health. Indeed, the public health, because of the  divers’  type of pollutions, is facing divers challenges for which urgent solutions are required.The biology provides approaches not only to deal with the pollution, but also to  obtain  economic  benefits. Some living  organisms  have  particular metabolisms  that allow  them  to  assimilate  and  metabolite  the polluting agents  and thus reduce the  impact  they have on both environment  and public health.  On  the other  hand,  the  metabolic  properties  of  specific organisms make  the  polluting  elements raw materials to  synthesize  other elements that are benefits  for  economy  and  non-toxic  for  the  ecology and  the  biohealth. Yet, other options such as the regulations and laws are  required  to improve the efficiency of these approaches.

Image of maternal love in Grigory Chukhray’s The QuagmireMemories of the Great Patriotic War contributed to the making of a national identity in Soviet Russia, and clear gender roles are evident in Soviet propaganda war art. The image of male soldiers demonstrates the obligation to defend the fatherland against the outside enemy. On the other hand, there are images of a mother cheering for her son or a mother lamenting over a fallen soldier. It is clear that the female image belongs to the reproductive function of motherhood. The establishment presents an ideal and urges the public to internalize it by themselves. Grigory Chukhray’s film The Quagmire’s 1977 mother, however, hides her young son, who was conscripted to the front. The  film casts doubt on the Soviet war myth and asks “Why do mothers have to be reconciled to lose their sons in order to defend the fatherland?” That’s why the military purged the film from the screen. Obraz miłości macierzyńskiej w filmie Grigorija Czuchraja TrzęsawiskoWspomnienia i obrazy Wielkiej Wojny Ojczyźnianej odegrały ważną rolę w kształtowaniu tożsamości obywateli Rosji Radzieckiej. W sowieckiej propagandzie wojennej wyraźnie widać hierarchię genderową. Wizerunek żołnierza mężczyzny odnosi się do obowiązku obrony ojczyzny przed zewnętrznym wrogiem. Natomiast wizerunek matki wiwatującej na cześć zwycięstwa syna lub rodzicielki lamentującej nad poległym żołnierzem kojarzony jest z macierzyństwem. Film Grigorija Czuchraja Trzęsawisko Трясина opowiada historię matki ukrywającej powołanego do wojska i wezwanego na front syna. Film, który wkrótce po premierze wycofano z  dystrybucji, stawia pytania dotyczące funkcjonowania radzieckich mitów wojennych oraz sytuacji kobiet, które nie chcą się pogodzić ze śmiercią swych synów broniących ojczyzny.
