Ambiguity as Discursive Strategy: A Critical Analysis of Pakistani Political League’s Selected Discourse Regarding Covid-19
Authors: Khan Muhammad A. , Satti Sumra M. J. 
Published: September 2021

This study unearths the ambiguities found in the discourseof prominent Pakistani political league during the outbreak of the pandemic covid-19 from the perspective of critical discourse analysis (CDA). CDA is an approach to the analysis of discourse which considers language as a social practice and takes particular interest in the ways in which ideologies and power relations are expressed through language (Fairclough, 2015). This paper presents a reflection to unveil the discursive strategies which are being used by the major Pakistanipolitical parties’ leaders as they did not come up with any plan of action pertaining to covid-19 yet. These statements are merely based on criticism only for the sake of criticism without any systematic planning and logical way out to get rid of this critical situation. This analysis is guided by the framework of Fairclough’s model of CDA (2015) which consists of three inter-related processes of analysis tied to three inter-related dimensions of discourse. This paper highlights the ideological perspective of Prime minister Imran Khan, opposition leaders i.e., PML-N leader ShahbazShareef, Chairman Pakistan People’s Party, Bilawal Bhutto Zardari and MolanaFazal-u-Rehman. This study found out that the statements which are given by the major political parties on different political forums are full of vague ideas and uncertainty about Coronavirus outbreak which is, in a way,an evidence regarding their failure to understand and tackle the dire situation.

Silver nanowire films are good candidates to be used as transparent conductive films that could be widely utilized in organic photoelectronic devices such as polymer solar cells. However, their application is usually limited, as they are mainly used as top electrode materials; otherwise, they would be prone to complex transferring processes. In this study, we successfully prepared device-level ZnO-covered silver nanowire (AgNWs/ZnO) films. ZnO was prepared by a spray pyrolysis method using zinc-ammonia solution at a relatively low temperature (95°C). The films showed good adhesive properties to the glass substrate, considering it withstood the process of applying polyimide tapes on the surface and tearing them off more than 100 times. It also exhibited good conductivity (∼24 Ω/sq) with high transmittance in the visible range (&gt;80%). After a simple polish and patterning, AgNWs/ZnO showed a good performance as a sub-electrode for polymer solar cells. The PM6:Y6 devices achieved a high power conversion efficiency of 8.37% with an open-circuit voltage of 0.81 V, a short-circuit current density of 18.18 mA/cm2, and a yield of 81.25%. This indicates that the technology has a good prospect of large-scale fabrication of organic photoelectronic devices.

Objective: Aimed to investigate the epidemiological characteristics, clinical features, treatment, and short-term prognosis of COVID-19 in children.Methods: Retrospective analysis was conducted in 48 children with COVID-19 admitted to 12 hospitals in eight cities in Hunan province, China, from January 26, 2020 to June 30, 2020.Results: Of the 48 cases, Familial clusters were confirmed for 46 children (96%). 16 (33%) were imported from other provinces. There were 11 (23%) asymptomatic cases. only 2 cases (4%) were severe. The most common symptom was fever (n = 20, 42%). Other symptoms included cough (n = 19, 40%), fatigue (n = 8, 17%), and diarrhea (n = 5, 10%). In the early stage, the total peripheral blood leukocytes count increased in 3(6%) cases and the lymphocytes count decreased in 5 (10%) cases. C-reactive protein and procalcitonin were elevated respectively in 3 (6%) cases and 2 (4%) cases. There were abnormal chest CT changes in 22 (46%) children, including 15 (68%) with patchy ground glass opacity, 5 (22%) with consolidation, and 2 (10%) with mixed shadowing. In addition to supportive treatment, antiviral therapy was received by 41 (85%) children, 11 (23%) patients were treated with antibiotics, and 2 (4%) were treated with methylprednisolone and intravenous immunoglobulin. Compared to 2 weeks follow-up, one child developed low fever and headache during the 4 weeks follow-up, 3 (6%) children had runny noses, one of them got mild cough, and 4 (12%) children had elevated white blood cells and lymphocytes. However, LDH and CK increased at 2 weeks and 4 weeks follow-up. 2 weeks follow-up identified normal chest radiographs in 33 (69%) pediatric patients. RT-PCR detection of SARS-CoV-2 was negative in all follow-up patients at 2 and 4 weeks follow-up. All 48 pediatric patients were visited by calling after 1 year of discharge.Conclusions: Most cases of COVID-19 in children in Hunan province were asymptomatic, mild, or moderate. Close family contact was the main route of infection. It appeared that the younger the patient, the less obvious their symptoms. Epidemiological history, nucleic acid test, and chest imaging were important tools for diagnosis in children.

Background: We previously reported that a computational modeling-guided antiarrhythmic drug (AAD) test was feasible for evaluating multiple AADs in patients with atrial fibrillation (AF). We explored the anti-AF mechanisms of AADs and spatial change in the AF wave-dynamics by a realistic computational model.Methods: We used realistic computational modeling of 25 AF patients (68% male, 59.8 ± 9.8 years old, 32.0% paroxysmal AF) reflecting the anatomy, histology, and electrophysiology of the left atrium (LA) to characterize the effects of five AADs (amiodarone, sotalol, dronedarone, flecainide, and propafenone). We evaluated the spatial change in the AF wave-dynamics by measuring the mean dominant frequency (DF) and its coefficient of variation [dominant frequency-coefficient of variation (DF-COV)] in 10 segments of the LA. The mean DF and DF-COV were compared according to the pulmonary vein (PV) vs. extra-PV, maximal slope of the restitution curves (Smax), and defragmentation of AF.Results: The mean DF decreased after the administration of AADs in the dose dependent manner (p &lt; 0.001). Under AADs, the DF was significantly lower (p &lt; 0.001) and COV-DF higher (p = 0.003) in the PV than extra-PV region. The mean DF was significantly lower at a high Smax (≥1.4) than a lower Smax condition under AADs. During the episodes of AF defragmentation, the mean DF was lower (p &lt; 0.001), but the COV-DF was higher (p &lt; 0.001) than that in those without defragmentation.Conclusions: The DF reduction with AADs is predominant in the PVs and during a high Smax condition and causes AF termination or defragmentation during a lower DF and spatially unstable (higher DF-COV) condition.

Background: Insomnia is a widespread problem that can lead to the occurrence of other diseases and correlates closely with sympathetic nerve hyperactivation. Obesity-induced hepatic steatosis is mediated by sympathetic overactivation. However, it remains unclear whether insomnia may cause hepatic steatosis. The goal of this study was to preliminarily investigate whether insomnia caused hepatic steatosis in rats via sympathetic hyperactivation.Methods: A total of 32 Sprague-Dawley male rats were divided randomly into four groups: model, sympathetic denervation (Sd), estazolam, and control (eight rats/group). Model group received sustained sleep deprivation using the modified multiple platform method. In the Sd group, rats underwent sleep deprivation after receiving Sd by 6-hydroxydopamine (6-OHDA). Estazolam group: the rats concurrently received sleep deprivation and treatment with estazolam. The other eight rats housed in cages and kept in a comfortable environment were used as control. Blood samples were obtained for analysis of plasma lipids and hepatic function. Sympathetic hyperactivation-related indexes and hepatic steatosis in liver tissues were tested.Results: Liver enzymes, plasma lipid levels, and hepatic steatosis were elevated in insomnia rats, and sympathetic hyperactivation was found. Insomnia-induced hepatic steatosis was effectively lowered with pharmacological ablation of the hepatic sympathetic nerves. Furthermore, the treatment of insomnia with estazolam inhibited sympathetic activation and reduced hepatic steatosis.Conclusion: Sustained sleep deprivation-induced insomnia promotes hepatic steatosis in rats possibly by mediating sympathetic overactivation.

Campylobacter jejuni is the most frequent cause of bacterial gastrointestinal food-borne infection worldwide. The transmission of Campylobacter and Arcobacter-like species is often made possible by their ability to adhere to various abiotic surfaces. This study is focused on monitoring the biofilm ability of 69 strains of Campylobacter spp. and lesser described species of the Arcobacteraceae family isolated from food, water, and clinical samples within the Czech Republic. Biofilm formation was monitored and evaluated under an aerobic/microaerophilic atmosphere after cultivation for 24 or 72 h depending on the surface material. An overall higher adhesion ability was observed in arcobacters. A chi-squared test showed no association between the origin of the strains and biofilm activity (p > 0.05). Arcobacter-like species are able to form biofilms under microaerophilic and aerobic conditions; however, they prefer microaerophilic environments. Biofilm formation has already been demonstrated at refrigerator temperatures (5 °C). Arcobacters also showed higher biofilm formation ability at the temperature of 30 °C. This is in contrast to Campylobacter jejuni NP 2896, which showed higher biofilm formation ability at temperatures of 5–30 °C. Overall, the results demonstrated the biofilm formation ability of many strains, which poses a considerable risk to the food industry, medical practice, and human health.

The article observes methodological principles of design approach to goods’ design. It is stated, that the processes of globalization requires maximum adaptation of education and science to the human subject-spatial environment and surroundings. We proved the importance of this approach considering, while the role of design and its social function and active influence on the economy and culture observing. Formation of the creative person of the future labor training teacher should be based on a wide range of humanitarian disciplines (ergonomics, design, culture, organization of production of economical driving) and carried out on methodological principles of design approach to the goods’ design. The basic product features (social, instrumental, adaptive, effective, integrative), three subsystems ("man - product - environment", "goal - the product - the result," "personality - the product - society") define human activities. It is stated that Cultural component is prerequisite for the design of goods.
CONFLICTS IN STUDENT GROUPS WITH DIFFERENT COMPOSITION BY SEX
Authors: Myroshnyk O. 
Published: September 2021

The article is devoted to the study of the peculiarities of conflicts in mixed and same-sex student groups. The theoretical basis of the study was the position of the structural features of interpersonal interaction in the middle of the group, including the substructure of horizontal and vertical relationships in the instrumental and expressive spheres of group activity. The study of conflict in student groups was based on the analysis of the characteristics of interpersonal relationships between group members in certain areas. To study the peculiarities of conflict in groups of different sexes, a questionnaire was developed, which provided an opportunity to determine the overall assessment of conflict, conflict in the vertical and horizontal subsystems of group activity, as well as in its instrumental and expressive areas. 188 students from 10 academic groups of the higher educational institution took part in the survey. Of these, six were sexually homogeneous and four heterogeneous. According to the results of the survey, the gender composition of student educational groups is more related to the emotional component of group activity and the horizontal substructure of intragroup relationships. These trends were confirmed using the methods of mathematical statistics (Student’s t-test).
The results suggest that gender-mixed academic groups are more resistant to conflict triggers than homogeneous ones. However the composition of the group on the basis of gender can not be considered a factor that directly determines the conflict in the field of solving business problems, as well as interaction with teachers, officials of the dean’s office and student government.
CREATIVE THINKING AND IMAGINATION IN THE STRUCTURE OF JUNIOR SCHOOLCHILDREN CREATIVITY
Authors: Yanovska T. 
Published: September 2021

This article is devoted to the theoretical analysis of the problem of psychological features of the development of creative thinking of children of primary school age. Thinking is characterized as a cognitive process in which objects and phenomena of reality are reflected in their essential features, connections and relationships. Thinking arises on the basis of practical activities of sensory cognition. The difference between thinking and other mental processes is that it is almost always associated with the presence of a problem situation, the task to be solved and the active change of the conditions in which the task is set. The paper reveals the essence of the concept of “creative thinking” and analyzes its criteria.
Creative thinking is seen as a type of thinking characterized by the creation of a subjectively new product and new formations in the cognitive activity on the way to its formation. The theory of creative thinking is substantiated, which contains many different approaches to determining its mechanisms and patterns: dialogic, dialectical, critical, reflexive, lateral, positive thinking. The peculiarities of the formation of creative thinking in primary school students are substantiated and the methods of its development are analyzed, namely: the development of students’ independence, their ability to move independently from one stage to another, mastering the ability to find the most rational way to solve non-standard problems.
The main methods of research of psychological features of development of creative thinking of junior schoolchildren are analyzed: the technique “Drawing of figures” (modification of the technique of E. Torrens, developed by O. Dyachenko), which is aimed at assessing the abilities of junior schoolchildren to productive imagination (figurative creativity); the method “Invent a game” (according to R. Nemov) is aimed at assessing the flexibility, non-standard, originality of the child in the field of verbal creativity; Renzulli's creativity questionnaire (modified by O. Tunik) allows to diagnose the level of development of creative thinking (creativity) of primary school children by identifying the creative initiative of primary school students by the method of experts.The sample, stages of research are characterized and the received results of studying of psychological features of development of creative thinking of pupils of elementary school are analyzed.

A termografia é eficiente para detecção da temperatura da superfície corporal e pode ser utilizada como método auxiliar de diagnóstico de processos inflamatórios e na avaliação de padrões cicatriciais, o que permite sua ampla utilização na Medicina Veterinária. O procedimento tem ganhado destaque, pois trata-se de técnica não invasiva, indolor, de baixo custo e segura, pois dispensa a necessidade do uso de contrastes, sedação e radiação. O objetivo desse artigo é analisar a eficiência do uso da termografia na avaliação da biocompatibilidade em reparação tecidual traqueal, bem como identificar processos inflamatórios após a implantação da prótese impressa em impressão 3D de náilon associado ao elastômero termoplástico- PCTPE. Quinze coelhos machos, da linhagem Nova Zelândia Branco (Oryctolagus cuniculus), foram distribuídos em três grupos de períodos de avaliação diferentes (sete, 15 e 30 dias). As próteses tridimensionais foram implantadas após ressecção completa de três anéis traqueais. A avaliação das imagens termográficas foi efetuada no local de implantação da prótese traqueal no momento anterior ao procedimento cirúrgico e imediatamente antes da eutanásia. Houve diferença significativa entre os grupos, sendo que aos 30 dias a temperatura mínima (p=0,0357), média (p=0,0135) e máxima (p=0,0058) foi menor quando comparado com os demais grupos. Isso justifica-se devido ao fato desse grupo se enquadrar na fase de maturação da reparação da ferida, onde não há mais inflamação ou formação de tecido de granulação, o que faz com que as temperaturas assumam valores mais baixos. Concluiu-se então a eficácia da técnica na detecção de padrões inflamatórios e cicatriciais.
