Shield-Net: Matching Supply with Demand for Face Shields During the COVID-19 Pandemic
Authors: Alcock Rebecca , Boutilier Justin J. , Siddiq Auyon 
Published: January 2022

The initial months of the COVID-19 pandemic were marked by widespread shortages of personal protective equipment (PPE) because of surging demand and a fragile global supply chain. In response, many domestic suppliers pivoted to producing PPE, such as masks and face shields, made possible by low material costs and simple designs. A key challenge that remained was the lack of an established marketplace for nontraditional suppliers of PPE to connect with healthcare facilities in need. To address this inefficiency, we launched an online platform, Shield-Net, to match requests for face shields with new suppliers of PPE. Our platform was based on an optimization model that produced supplier-requester pairs and took into account request urgency, request size, production capacity, location, and product type. During the period of March to September 2020, Shield-Net produced 390 matches, resulting in the shipment of more than 50,000 face shields to 68 unique requesting organizations. Supplier-requester proximity was found to be the only statistically significant variable in the success of a match. In this paper, we discuss the development and impact of our matching platform, as well as lessons learned during its operation. History: This paper was refereed.

Evaluation of Warning Methods for Remotely Supervised Autonomous Agricultural Machines
Authors: Edet Uduak , Mann Danny D. 
Published: January 2022

HighlightsHumans who supervise autonomous agricultural machines require some type of warning to perceive abnormal conditions in the machine or its environment.Visual and tactile warnings were the most suitable warning methods for in-field and close-to-field remote supervision.This study will help improve the performance of remote supervisors and minimize unexpected incidents or liabilities during operation of autonomous machines.Abstract. As agricultural machinery moves toward full autonomy, human supervisors will need to monitor the autonomous machines during operation and minimize system failures or malfunctions. However, to intervene in an emergency, the supervisor must first recognize the emergency in a timely manner. Existing warning devices rely on the human visual, auditory, and tactile senses. However, these warning methods vary in their ability to attract attention. Hence, it is important to determine which warning method is best suited to draw the attention of a remote supervisor of an autonomous machine in an emergency. To achieve this objective, participants were recruited and asked to interact with a simulation of an autonomous sprayer. Seven warning methods (presented alone or in combinations of visual, auditory, and tactile sensory cues) and four remote supervision scenarios (in-field, close-to-field, farm office, outside the farmland) were considered in this study. The findings revealed that a combination of tactile and visual methods was most suitable for in-field and close-to-field remote supervision, in comparison to the other warning methods. However, there was insufficient evidence to recommend the best warning methods for supervisors at the farm office or outside the farmland. This study will help improve the performance of remote supervisors and minimize unexpected incidents during field operations with autonomous agricultural machines.

Published: January 2022

Background: Denture stomatitis is a type of Candida-associated infection that mainly affects the palatal mucosa. Candida albicans is one of the normal flora that is considered to be the primary etiologic agent in the pathogenesis of denture stomatitis. Denture decontamination is necessary to prevent denture stomatitis. One method of decontamination is by immersing removable dentures in an antifungal solution. Parsley (Petroselinum crispum) is a medicinal plant showing antifungal activity. Objectives: To determine the effectivity of immersion of acrylic resin Plate in parsley extract on inhibition of growth of Candida albicans. Methods: The effectivity of immersion of heat-cured acrylic resin plates in parsley extract on inhibition of C. albicans growth was tested using an experimental laboratory study with a post-test-only control group design. Thirty samples were divided into 5 groups as 0.01%, 0.02%, and 0.05% parsley ethanol extract, 0.1% sodium hypochlorite, and sterile aquadest. The number of colony forming units per mL was obtained after calculating the colonies on SDA media, allowing the minimum inhibitory concentration (MIC) obtained according to the formula. Results: 0.01% parsley ethanol extract is MIC with a mean of 7.4 CFU / ml, which inhibited the growth of C. albicans by 31.05%. The Kruskal Wallis test (p<0.001) results indicate that there is an effectivity of immersion of acrylic resin plate in parsley extract on inhibition of growth of C. albicans. Conclusions: The immersion of acrylic resin plates in parsley ethanol extract with a concentration of 0.01%, 0.02%, and 0.04% has effectivity on the inhibition of growth of C. albicans.

I wanted to honour your journal, and you spat in my face: emotive (im)politeness and face in the English and Russian blind peer review
Authors: Larina Tatiana , Ponton Douglas Mark 
Published: January 2022

Abstract
This study explores the degree to which politeness and emotive considerations are respected across two different academic traditions and linguistic settings; in Russian and English blind peer reviews. It analyses 120 authentic reviews (70 Russian and 50 British English) with the negative verdicts: “Reject” and “To be resubmitted after substantial revisions” using a pragmatic, contextual and contrastive methodology. Drawing on (im)politeness theory, intercultural pragmatics and cultural studies, we explore the construction of alternative meanings in reviewers’ messages, and theorize that consideration for the face requirements of the reviewee may account for the lingua-cultural choices of the reviewer. We explore structural, linguistic, communicative and stylistic differences in English and Russian reviews. The results show that despite reviewers’ individual styles there are some culture-specific traits in the styles of reviews. Emotive politeness, we have suggested, appears to be (pre)determined by the sociocultural context and is more typical of English communication than Russian. We account for the differences in terms of sociocultural context, value differences and the use of different mechanisms of politeness. Our results confirm that politeness is not only social, but is also a psychological phenomenon based on empathy, whose manifestations may vary across cultures.

Aim. To assess the features of clinical and hemodynamic characteristics and the severity of coronary involvement in patients with chronic coronary artery disease (CAD) with and without diabetes.Material and methods. The study included 100 patients with stable CAD, which were divided into two groups: group I (mean age, 57,9-1,04 years, male/female 35/14) — 49 patients with CAD and type 2 diabetes, II — (60,2-0,9 years, 34/17) — 51 patients without SD. Along with behavioral and biological risk factors, clinical and hemodynamic characteristics were analyzed. All patients underwent coronary angiography.Results. The presence of diabetes in patients with CAD was associated with abdominal obesity and comorbidity of somatic diseases. Among group I patients, electrocardiographic signs of left ventricular hypertrophy, conduction abnormalities, accompanied by a decrease in the left ventricular ejection fraction, impaired diastolic function, and high mean pulmonary artery pressure were significantly more often detected. In patients with CAD and type 2 diabetes, significant right coronary artery (CA) stenoses were more often recorded (39%), while in patients without diabetes, the anterior descending artery was the most susceptible to atherosclerosis. In group I, stenosis of the distal CA third was detected 1,5 times more often (p<0,001), and their diffuse multivessel lesion prevailed by 28% (73% and 45%, respectively, p<0,005). The average SYNTAX score in patients with and without diabetes was 29,2±0,8 vs 22±0,7, respectively (p<0,0005).Conclusion. In patients with CAD and diabetes, more pronounced atherosclerotic coronary involvement (diffuse multivessel CAD) was revealed, which should be taken into account when planning further treatment. The risk of adverse cardiovascular events will always be present with percutaneous coronary interventions.

OBJECTIVE: The purpose of this study is to investigate the immunomodulatory effect of beta glucan in an experimental model of intraabdominal bacteremia induced by S. aureus.MATERIAL AND METHODS: Thirty Wistar albino rats were randomly divided into four groups. Staphylococcus aureus bacteremia (SAB), treatment with cefazolin, treatment with beta glucan, treatment with both cefazolin and beta glucan groups were constituted respectively. 4 mg/kg beta glucan and 100 mg/kg cefazolin were given after 12x10 8 cfu/ml 1 cc S. aureus was given intraabdominally. After two hours, 0.5 cc blood was drawn and put into blood culture bottles. Levels of Tumor necrosis factor-alpha (TNF-α), interleukin-1 (IL-1), interleukin-6 (IL-6), and Interferon gamma (IFN-γ) were evaluated after 4th, 6th and 8th hours.RESULTS: According to the biochemical analyses; At the end of the study it was seen that beta glucan increased the level of IFN-γ at 6th hour, but did not at 4th and 8th hours. This increase became more apparent at 6 th hour when it was given with cefazolin. However IFN-γ levels were found to be higher in the group which cefazolin was given than beta glucan was. As the level of serum TNF-α was evaluated, although there was a supression at 8th hour, it was found to be higher in the group which beta glucan was given than the SAB group. Serum IL-1 levels were higher at 4th, 6th and 8th hours in the group beta glucan was given than the SAB group. Although a decline in IL-1 level was detected in the group which cefazolin was added to beta glucan at 8th hour, this level was found to be higher than the SAB group. When the serum IL-6 level was evaluated, an increase in release of IL-6 was found in the group beta glucan was given in the first 8 hours when it was compared with SAB group. When beta glucan was given with cefazolin, it was observed that IL-6 increased to the highest level at 8th hour.CONCLUSIONS: This experimental intra-abdominal bacteremia model, demonstrated that beta glucan did not supress the production of TNF-α and IL-1, and increased the release of IL- 6 and IFN-γ, especially in the first hours. According to these results, no significant knowledge could be obtained about the benefit of using beta glucan in the treatment of experimental model of intraabdominal bacteremia.

Published: January 2022

Teaching speaking to Indonesian EFL young learners is still problematic. It happens not only because English is not used in daily activities but also the government’s regulation to some extent does not support that. This qualitative study aims to describe the problems faced by EFL students in the learning of English speaking with teachers’ perspectives. The samples of this research were three teachers from three different elementary schools in Jepara, Central Java, Indonesia. The data were collected by using questionnaire, interview, and classroom observation. The data were then analyzed by 1) memoing or transcribing the interview data, reading them to make notes and finding the most important information that might be useful for the study, 2) describing the data to find complete explanation of context, setting, and interactions of participants, 3) classifying data—to break down the obtained result and put it into categories, and 4) interpreting the data to find the meanings of the data by connecting the findings with previous studies, personal experience, and expert advice to find the best result. The result showed that EFL students’ problems in the learning of English speaking came from some factors. They are 1) Native language, 2) Age, 3) Exposure, and 4) Motivation, and 5) Learners’ Autonomy. Keywords: speaking, Indonesian EFL students, young learners

Published: January 2022

Background: The study aimed to observe the prevailing buffalo calf rearing practices and mortality patterns in the operational area of Dairy Vigyan Kendra (DVK), Vejalpur, Gujarat, India. Methods: Using the simple random sampling method, 240 buffalo owners from 24 villages of 6 talukas from the operational area of Dairy Vigyan Kendra were selected. The data were collected based on the interview schedule. Result: The majority of buffalo owners had not adopted the different management practices viz., provision of milk replacer, calf starter, mineral mixture, salt, deworming agent at every month up to six months and vaccine. An overall buffalo calf mortality was observed 24.26% in the study area. There was a higher mortality rate in male calves (45.00%) than female buffalo calves (14.58%) because of negligence towards the male calf. The mortality rate observed was higher during the first three months of age (90.98%) and during winter (45.08%). A negative and significant relationship was observed between some important calf rearing practices like colostrum feeding time, providing milk replacer, calf starter, concentrate feed, mineral mixture, dewormer and vaccines to calves with female buffalo calf mortality. Participation in various animal husbandry training programs and adoption of scientific management practices to large herd size farms will be helpful to reduce female buffalo calf mortality rate at the field level.
CRITICAL DISCOURSE ANALYSIS OF THE NEWS OF COVID-19 CORPSE SNATCHING PATIENT IN THE I-NEWS

Published: January 2022

The diction used in the news of corpse snatching of COVID-19 varies and has caused the public to panic. This study aims to show the structure of the media language used in The News of Corpse Snatching of COVID-19 patients in Pasuruan and the factors that caused the hundreds of people attempting to take the deceased's body forcefully. The primary data are the news of corpse snathing of COVID-19 patients in Pasuruan, uploaded on YouTube and the online news media i-News, and comments from netizens in the comments column. In addition, informant interviews were conducted to show the factors causing Corpse Snatching. Critical discourse analysis (CDA) is used for content analysis by describing three dimensions: text, discursive practice, and social practice. It was concluded that the media language used in the news text of the corpse Snatching in Pasuruan tends to use vocabulary that shows negative rather than positive actions. Moreover, the media emphasizes negative actions more than describing solution actions to become government policy steps. Based on informants and studies of the third dimension, hundreds of people who conducted the Corpse Snatching were caused because people hardly accept COVID-19 protocols since they hold Kejawen Islamic funeral traditions.

This study relates the discussion of discourse markers to their functions from a social context. It aims to identify discourse markers and analyze their function to construct a social situation in Steve Jobs’ speech delivered at Stanford Commencement Address. To analyze the data in this study, the researchers used a qualitative descriptive method. This study showed that the dominant discourse markers used were connective, followed by cause result, temporal adverb, and marker of response, respectively, in which the last marker was the least used. Furthermore, all discourse markers functioned to gain coherent message delivery in the speech by considering the “setting and scene," "participants," "ends,” “act sequence,” “key,” “instrumentalities,” “norms of interaction,” and “genre,” all of which were shortened in the acronym of “speaking.” Finally, based on its social situation, the present study is expected to broaden the understanding of discourse markers in a particular text.
