The conclusion of this reasearch is the influence of teaching method (Lecture, Recitation, and Grup in Work, Skill Training) and the level of Intellegence on Arabic learning Achievement in MAPK MAN 1 Surakarta. There were significant differences in Arabic learning using the lecture and recitation methods and students taught using group work methods and skills training. from the calculated r value greater than r table, namely rh = 0.49 0.44 = rt, There was a difference in the learning to students with low IQ or students in 1` lower IQ group. the calculated r value greater than the table, namely: rh = 0.78 0.44 = rt, The method of teaching group work and skills training can significantly improve students' learning in the experimental class when compared to the control group. This can be seen from the difference in the average value achieved by the two groups where the experimental group is greater than the control group, namely: 96 94.
Non-Professional Investors' Judgments of the Reliability of Fair Value Estimates—The Impact of Investor Mood
Authors: Chen Wei , Harding Noel , He Wen 
Published: May 2021

ABSTRACT
We study whether investor mood affects non-professional investors' judgments of the reliability of fair value estimates. In two experiments, we find that investor mood, which is a factor that is unrelated to the assessment of reliability across the fair value hierarchy, is associated with differences in the extent to which Level 1 fair values are perceived to be more reliable than Level 3 fair values. As mood becomes more positive, investors perceive greater differences in the extent to which Level 1 fair values are more reliable than Level 3 fair values. Importantly, we find that including brief definitions in the headings under which fair values are reported reduces the influence of mood over perceptions of reliability, and likely improves the effectiveness of fair value disclosures.
Is it a Tip or a Gift? Investigating Duberstein in the Modern Gratuity Era

Published: May 2021

ABSTRACT
In the modern era of social media, users frequently promote their acts of generosity. Included in these acts of generosity are tips to restaurant servers that exceed customary amounts. Due to the extraordinary amounts of the transfers, the proper tax treatment as a “gift” or a “tip” is called into question. In Commissioner v. Duberstein, the Supreme Court addressed gifts versus taxable transfers, but did not provide a clear test for taxpayers. In the 60 years since Duberstein, Congress has yet to address the call of Duberstein to create an appropriate test for gift treatment. In this paper, we analyze prior law on gifts and tips. Next, we apply the law to scenarios based on current events. Finally, we recommend that Congress address transfers where the appropriate treatment as a “gift” or a “tip” is in question.

OBJECTIVEDisparities in type 1 diabetes related to use of technologies like continuous glucose monitors (CGMs) and utilization of diabetes care are pronounced based on socioeconomic status (SES), race, and ethnicity. However, systematic reports of perspectives from patients in vulnerable communities regarding barriers are limited.RESEARCH DESIGN AND METHODSTo better understand barriers, focus groups were conducted in Florida and California with adults ≥18 years old with type 1 diabetes with selection criteria including hospitalization for diabetic ketoacidosis, HbA1c &gt;9%, and/or receiving care at a Federally Qualified Health Center. Sixteen focus groups were conducted in English or Spanish with 86 adults (mean age 42 ± 16.2 years). Transcript themes and pre–focus group demographic survey data were analyzed. In order of frequency, barriers to diabetes technology and endocrinology care included 1) provider level (negative provider encounters), 2) system level (financial coverage), and 3) individual level (preferences).RESULTSOver 50% of participants had not seen an endocrinologist in the past year or were only seen once including during hospital visits. In Florida, there was less technology use overall (38% used CGMs in FL and 63% in CA; 43% used pumps in FL and 69% in CA) and significant differences in pump use by SES (P = 0.02 in FL; P = 0.08 in CA) and race/ethnicity (P = 0.01 in FL; P = 0.80 in CA). In California, there were significant differences in CGM use by race/ethnicity (P = 0.05 in CA; P = 0.56 in FL) and education level (P = 0.02 in CA; P = 0.90 in FL).CONCLUSIONSThese findings provide novel insights into the experiences of vulnerable communities and demonstrate the need for multilevel interventions aimed at offsetting disparities in diabetes.

The Solitary Rover: Niceties of Frankl’s Logotherapy in Vallee’s Wild
Authors: K. J. Jissmon 
Published: May 2021

The meaninglessness of existential philosophy was celebrated and was at its peak until the formulation of the psychotherapic theories by Austrian neurologist and psychiatrist as well as a Holocaust survivor, Viktor Emil Frankl. Frankl introduced new psychoanalytic and psychotherapic terms into the realm of studies related to the complexities of human mind. It was in his seminal work, Man’s Search for Meaning (1946), that Frankl introduced the idea of Logotherapy, as a clinical as well as a psychological term. Frankl with his notion of logotherapy refuted the nihilistic aspects of existentialism and certain like philosophies.” Here, the protagonist, Cheryl Strayed, in Vallee’s Wild (2014) sets out for a journey to find out about herself and the ultimate meaning of her life. Cheryl, during her journey, leaves all of her material possessions and familial relations behind. Here, one may tend to see her as an “existential “one but in a more wider sense, she is not celebrating the meaninglessness, rather she strives hard to find a meaning in her life to live on. This paper opens a new outlook towards this movie, especially towards the character of Cheryl Strayed.

Abstract
Severe dengue infection is associated with life-threatening complications, including severe bleeding. The bleeding tendency is typically associated with the shock phase of infection, for which blood replacement may be needed. However, repetitive blood transfusion can lead to volume overload. Administration of recombinant activated factor VII (rFVIIa) might be used to counteract bleeding without inducing volume overload. We describe the case of a patient with severe dengue infection who presented with intractable bleeding; he was initially treated with massive blood transfusions, which resulted in volume overload. He was then treated with rFVIIa to reverse the bleeding. During the second week of his hospitalization, his hematocrit dropped precipitously, and autoimmune hemolytic anemia was diagnosed. Supportive treatment was provided until recovery. Autoimmune hemolytic anemia is a rare complication in adult patients with dengue. Supportive care was effective for this atypical complication.

Published: May 2021

Effect of citric acid as plasticizer on the electrochemical properties of liquid electrolyte has been studied. Liquid electrolyte was prepared by dissolving citric acid in 1% acetic acid with presence of lithium nitrate salt. Liquid electrolyte is characterized using a conductivity meter to measure the ionic conductivity value. Computer simulation of Density Functional Theory (DFT) with B3LYP/6-31G ++ (d, p) basic set was performed to identify the dominant functional group of citric acid when interact with lithium salt. Increasing the weight of citric acid has increased the ionic conductivity up to 44.89 mS/cm with an optimum weight of 4 g, while the ionic conductivity increases up to 43.00 mS/cm when the percentage of lithium nitrate salt increases up to 30%. The ionic conductivity increases as the salt percentage increases due the interaction between salt and functional group of citric acid. Based on computer simulation of DFT, Â the dominant functional group in citric acid that interact with lithium salt are carboxylic acid group which is located in the middle of the citric acid chain causing lithium ions to be more likely interact with citric acid.

Published: May 2021

Malignant melanoma and particularly metastatic melanoma represent a diagnostic challenge due to the wide variety of histologic patterns, resemblance to benign entities, and extensive range of clinical presentations. A high index of suspicion for melanoma is important for accurate diagnosis, especially when there is a previous history of malignancy. Here, we present a patient with a history of melanoma and locally metastatic melanoma, who subsequently developed a nodule on his right forearm near the site of his previous melanoma excision. Histologically, the melanoma appeared as granuloma annulare (GA) with benign cytologic features, but was identified as metastatic melanoma using SOX-10 immunohistochemical staining. Other malignancies, including lymphomas, leukemias, sarcomas, and cutaneous metastases of internal malignancies, have mimicked GA and interstitial granulomatous processes. Therefore, further immunohistochemical staining should be performed to assess for metastatic disease in the setting of a histological pattern that resembles a benign granulomatous process in a patient with a history of malignancy, including malignant melanoma.
Therapeutic targets in COVID-19 coagulopathy

Published: May 2021

В обзоре представлены сведения о некоторых биохимических и клеточных механизмах патогенеза потенциально смертельного вирусного заболевания, получившего название COVID-19, провоцируемого вирусами из семейства коронавирусов SARS-CoV-2. Наибольшую опасность для жизни и здоровья пациентов представляет коагулопатия, обусловленная ответной реакцией на инфекцию — чрезмерной генерацией клетками пациента внеклеточных мембранных нановезикул (ВМН), которые могут спровоцировать активизацию гемостаза, приводящую к разрушительной полиорганной недостаточности. Вирусы также способны генерировать внеклеточные везикулы, называемые виросомами. Встраивая вирусные компоненты в свои виросомы, вирусы повышают персистентность за счет маскировки своих геномов, умножая вирусную инфекцию. В статье охарактеризованы свойства нейтрофильных гранулоцитов, активирующихся при инфицировании, и представлены сведения о молекулярных механизмах действия их компонентов при попадании во внеклеточное пространство. ВМН уже имеют практическое применение в качестве вакцинных носителей для иммунизации человека и животных против многих инфекционных заболеваний. В настоящее время актуальнейшей темой, обуславливающей большой практический интерес, стала роль ВМН в индуцировании иммунитета против коронавирусной инфекции. Охарактеризованы другие возможные терапевтические мишени.
Virus-induced coagulopathy is a typical example of the tight connection between inflammation and thrombosis. These two reactions are linked by pro-inflammatory agents, generated by activated neutrophils and their neutrophil extracellular traps (NETs). Extracellular membrane nanobubbles (EMNs), formed by a wide variety of cell types, have recently been identified as new entrants that play a key role in coagulopathy. EMNs directly and indirectly activate coagulation systems that lead to the further upregulation of inflammation and life-threatening organ dysfunction and thrombosis. EMNs are known to be responsible for the secretion, exchange, and transmission of important active biomolecules in COVID-19. Indeed, EMNs represent an essential mechanism in intercellular communication, and the roles of EMNs in infection and thrombosis have been increasingly recognized. The extracellular microvesicles of viruses, virosomes, represent a new type of infectious agents, which determines new therapeutic goals in solving the problems of controlling viral infections. Understanding the biological nature of all these microvesicles when studying them in vivo is of paramount importance for the development of diagnostic and therapeutic methods.
Self-regulation as a Mediator of Mindfulness and Physical Activity: A Narrative Review
Authors: Boyle Aaron , Mosewich Amber 
Published: May 2021

Mindfulness is gaining increased attention as a means of increasing physical activity (PA) participation. Given that only 15.4% of adult Canadians currently meet the Canadian Physical Activity Guidelines (Colley et al., 2011), it is imperative to find ways to increase PA among adults. One way to do this is to promote self-regulation skills as self-regulation is among the top predictors of PA participation (Teixeira et al., 2015). The purpose of this narrative review was to further understand the role of self-regulation as a potential mechanism by which mindfulness may be related to PA participation. Initially, 160 papers were identified by title for this review. After reading abstracts, 37 papers were identified as possibly relating to the topic of interest. Following full readings, 26 papers were included in the final review. Likely due to the novelty of this topic, there is limited research on the mechanisms by which mindfulness may be related to physical activity. Review of the literature suggests that self-regulation appears to be a promising mechanism by which mindfulness could improve physical activity participation (Shapiro et al., 2006; Samdal et al., 2017), as self-regulation has been shown to play an important role in behaviour change, however, other alternative mechanisms include improved self-efficacy, as well as improved satisfaction (Neace et al., 2020; Tsafou et al., 2016). The authors conclude that more research on the mechanisms of mindfulness on PA, specifically self-regulation as a mechanism, could foster more knowledgeable intervention practices, and consequently improve mindfulness-based interventions efficacy.
Terahertz radiation may not alter rat basophilic leukemia cell membrane permeability to propidium iodide

Terahertz radiation (THz) technology is fast-growing, with applications in sensing, security, monitoring and pharmaceutical industries. Since it is non-invasive, THz has been used as a diagnostic and therapeutic tool in medicine but its specific effects on biological systems is still largely under-studied. THz has been used to image tissues and cells mainly because it allows for identification of morphological features without the need for fluorescent or radioactive labels, but the potential effects of high intensities of THz radiation are currently not well understood. One of the hypotheses that has been proposed for possible effects of THz on living cells, is that it disrupts the cell membrane and induces increased permeability. To test this hypothesis we exposed a rat basophilic leukemia cell line (RBL-2H3) to non-thermal intense THz radiation (duration, dose, etc) and observed the internalization of propidium iodide, a fluorescent intercalating agent that binds to DNA. We did not observe any changes in RBL-2H3 fluorescence following exposure to these intense THz pulses suggesting that exposure of RBL-2H3 to THz radiation may not increase their membrane permeability. These experiments were preliminary and further optimization and analysis is required before we can make definitive conclusions. However, our preliminary observations have set a baseline of RBL-2H3 internalization of propidium iodide, show that it is possible to expose RBL-2H3 cells to THz radiation using our configuration, and set the stage for future experiments.

Methodology.The work is based on the system approach. It makes possible to consider dynamic visual communications as the integral area for the communication of a human and the environment. The results of the compositional and structural and functional analysis helped to make the generalization and systematization of the ways for the visual dynamic creation on bus stops. Results. In the study we consider the bus stop as the visual dynamic system with the intensive communicational processes, which are based on the integration of different forms of human sensitive experience and the urban environment. We proved that subject-visual, visual-sound, visual-tactile and digital visual communications substantiate the transformation of the information perception and deepen it. At the same time a human becomes a part of the communication. Bus stop turns into the experimental location and provides increased emotionality of the communicational processes due to the forming of the immersive context. The designer can afford to program the people’s behavior in the system of the visual dynamic communications. It allows creating opportunities for the stationary bus stops to adapt to the changing external living conditions. Scientific novelty.In the work we rethink the role of the visual communication in the bus stop structure and in the whole environment. The visual communication has an experimental nature. It proves that the communications in the environment are developing towards the increasing dynamics and immersion. Practical significance. The results of the study show the ways to increase the level of dynamics of the visual communications on bus stops. It will make the perception of the informational messages more effective and will make the urban environment more aesthetic. The features of the dynamical designing, which were found, can be used by specialists with the purpose of the designing of the modern environment. In addition, they can be used as the educational technology to form the system thinking of designers.

Purpose. Investigate the national component and stylistic features of satirical graphics of P. Kovzhun and E. Kozak in popular Lviv humorous magazines of the interwar period. Methodology. The applied art analysis makes it possible to investigate, identify, compare and describe the features of satirical graphics and artistic design of Lviv humorous publications of the interwar period. Comparative and historical methods help to trace the work of leading artists in Lviv satirical periodicals of 20–30s years of XX century. Results.Stylistic features of satirical graphics by P. Kovzhun and E. Kozak in Lviv humorous magazines of 20–30s years of the XX century are determined. It is noted that the artistic style of these artists was influenced by Western European art trends, such as: modernism, expressionism, cubism, futurism. In their graphics, cartoonists use similar tools to achieve a greater effect – grotesque, allegory, zoomorphism. It is traced that each of these artists had his own individual style of satirical illustration, which was supported by national motives. The article draws parallels between German and Lviv satirical magazine graphics on the example of the magazine "Simplicissimus". It was found out that P. Kovzhun and E. Kozak, as leading artists of humorous publications, in addition to highly artistic illustrations, made high-quality graphic design for the magazines «Maski», «Zyz», «Komar». The artistic design of the covers and technical features of these publications are analyzed. Most satirical magazines had a symmetrical hierarchical composition of the title page with a limited polychrome palette. The logo-name on the cover of the magazine was harmoniously perceived together with the title illustration. The cover was made in color, usually in two colors, magazine covers were monochrome. The semantic load of visual satirical material in humorous editions of the interwar period is established. Scientific novelty. The satirical graphics with an emphasis on the national component of the leading illustrators P. Kovzhun and E. Kozak in Lviv humorous magazines of 20–30s years of the XX century is investigated and compared. The peculiarities of the design of the covers of popular Lviv satirical editions of the interwar twentieth century, such as «Maski», «Zyz», «Komar» are determined. Practical significance. Given data on satirical graphics in Lviv magazines of the 20–30s of the XX century and their artistic design will help in understanding the traditions of Ukrainian Galician satirical illustration and magazine design.
