Synchronized Action Framework for Detection of Coordination on Social Media
Authors: Magelinski Thomas , Ng Lynnette , Carley Kathleen
Published: March 2022

The study of the coordinated manipulation of conversations on social media has become more prevalent as social media’s role in amplifying misinformation, hate, and polarization has come under greater scrutiny. We discuss how successful generalized coordination detection algorithms could be used to reinforce existing power imbalances, such as those between marginalized groups and government agencies. We propose an alternative method of identifying manipulation—detecting synchronized actions—which reduces this risk. We further consider how responsible coordination detection may be carried out by analyzing synchronized actions. We propose a synchronized action framework for detecting automated coordination by constructing and analyzing multi-view networks. We validate our framework by examining a large Twitter dataset surrounding the Reopen America conversation from 2020. We first discover three simple coordinated campaigns, and then investigate synchronized actions between users discussing the protests that could be consistent with covert coordination. This task is far more complex than examples evaluated in prior work, which demonstrates the need for our multi-view approach. Next, we identify a cluster of suspicious users and detail the activity of three members. These three users amplify protest messages using the same hashtags at very similar times, though they all focus on different states. This analysis highlights the potential usefulness of coordination detection algorithms in investigating amplification, as well as the need to carefully and responsibly deploy such tools.
International Community Engagement: Transforming Students and Residents

Published: March 2022

In the 21st century, postsecondary education is increasingly shifting its curricular focus to include community engagement through service-learning and study abroad in response to the need to prepare global citizens. This approach is particularly important in the field of nursing and public health because of the challenges of delivering healthcare to underserved communities and diverse patient populations with complex and chronic conditions. At Clayton State University, an HBCU in Morrow, Georgia, courses across disciplines are infused with community engagement activities. One such course was a service-learning study abroad course for nursing students that took place in Guadalajara, Mexico. A pilot study was conducted using a mixed-methods approach. Results indicated that students experienced moderate to high perspective transformation through critical reflection, and participants at the health fair showed significant knowledge increase on four of the health topics presented by the students. An analysis of the students’ reflective narratives showed themes of language acquisition competency, nursing skill competency to function in a foreign environment, and change in cultural perspective. This pilot study contributes to the body of knowledge on the impact that community engagement can have on a diverse population of students and the international communities served.

Authors: Berryhill Blake , Morgan Holly , Wilson Elizabeth , Ruggles Hannah
Published: March 2022

Research supports the idea that positive family/school community partnerships during middle school can enhance student success. Thus schools are partnering with local universities to increase school and student outcomes. In order to support local middle schools, The University of Alabama created the Middle School Parent Teacher Leadership Academy, a training program that prepares middle school parent and teacher leaders with the skills to strengthen school and student outcomes. Using a mixed methods design, we analyzed pilot data from the first year of the Academy on parents’ and teachers’ leadership behaviors and self-efficacy. Pretest and posttest results showed that parent and teacher participants significantly increased their leadership behaviors. Qualitative thematic analysis revealed answers to the question: “What has the Academy meant to you?” as follows: 1) Facilitates parent-teacher collaboration, 2) Increases parent and teacher school leadership behaviors, 3) Enhances parent and teacher school leadership self-efficacy, 4) Increases opportunities for school change, and 5) Increases parental-school involvement. Implications and future directions are discussed.
Promoting Civic Knowledge and Political Efficacy Among Low-Income Youth Through Applied Political Participation
Authors: Alvarez Padilla Yesenia , Hylton Mary , Sims Jennifer
Published: March 2022

Studies indicate growing disparities in youth civic knowledge and political efficacy based on socioeconomic status, parental educational attainment, and race. Most studies of youth political participation focus on the effect political efficacy and civic knowledge have on political participation. Few report on the effect political participation has on political efficacy and civic knowledge. This article describes an intervention that coupled civic literacy workshops with applied political participation to increase the civic knowledge and political efficacy of low-income, ethnically diverse high school students. Over three years, 47 high school students enrolled in Upward Bound participated in a six-hour civic literacy workshop. Upon conclusion of the workshop, students spent a day meeting with legislators and attending legislative hearings. Results indicate increases in political efficacy and significant increases in civic knowledge among the youth after both the workshop and the visits with elected officials.

Keeping the Promise of Community-Based Participatory Research: Integrating Applied Critical Rhetorical Methods to Amplify the Community’s Voice for Trial Development
Authors: Mocarski Richard , Eyer Joshua , Hope Debra , Meyer Heather , Holt Natalie , Butler Sim , Woodruff Nathan
Published: March 2022

Community-based participatory research (CBPR) represents an important improvement in the integration of marginalized voices into research programs by including community members in the designs, conduct, and dissemination of studies. CBPR often features a social justice component, generating studies designed to reduce societal disparities and improve outcomes for disenfranchised groups. However, the practical implementation of CBPR usually fails to capitalize on this promise, using the same traditional research methodologies, leadership structures, trial designs, and research questions that inculcate researcher bias. In response to the problem, we propose a new solution: Applied critical rhetorical research (ACRR) integrated into the CBPR approach to clinical health research. ACRR research combines critical/cultural studies and rhetorical methods to amplify the figurative voice of marginalized populations. ACRR can expose how majority power (i.e., hegemony) manifests in social institutions like healthcare and government, where its meanings and subjectivities are absorbed. ACRR analyses enhance CBPR by shaping research in directions that reduce stigma, unintended disenfranchisement, and culturally bound bias, increasing the yield from CBPR for researchers and the community.
Serial prostate magnetic resonance imaging fails to predict pathological progression in patients on active surveillance

Published: March 2022

Introduction: Limited data guide urological practice when employing prostate magnetic resonance imaging (MRI) in active surveillance protocols. To determine the ability of prostate MRI to predict pathological progression in active surveillance patients, we correlated findings of serial MRI with results of surveillance biopsies.
Methods: Patients on active surveillance with greater than or equal to two prostate MRI and greater than or equal to two prostate biopsies were included. Prostate Imaging-Reporting and Data System (PI-RADS) score upgrade, as assigned by experienced radiologists, was used to assess the ability of imaging to predict pathological biopsy progression. Imaging test statistics and the odds ratio of pathological progression according to MRI upgrade were calculated.
Results: Of 121 patients meeting criteria, 36 (30%) demonstrated MRI upgrade. Biopsy progression was noted in 55 patients (46%). Of these, 20 patients (37%) had biopsy progression predicted by MRI upgrade, while the remaining (n=35) had no lesion upgrade on prostate MRI. Conversely, among those with no biopsy progression (n=66), 16 patients (24%) had a false-positive upgrade on serial MRI. We report a sensitivity and specificity of MRI change for pathological progression of 36% and 76%, respectively. Although MRI change was associated with a positive predictive value of 56% for pathological progression, patients with a high-suspicion lesion (PI-RADS >3) at any time were more likely to experience disease progression, (odds ratio 3.3, 95% confidence interval 1.6–8.0, p<0.01).
Conclusions: Given its modest sensitivity/specificity, serial prostate MRI should be used judiciously as a surveillance tool. However, when prostate MRI demonstrates a PI-RADS >3 lesion, a high index of suspicion should be maintained, as these patients are more likely to progress on active surveillance.

Structures, stabilities and infrared spectra of AgnCr clusters (n=2-12) by density functional theory calculation
Authors: Ngo Lan , Nguyen Mai , Tung
Published: March 2022

Nanoclusters have been emerging as potential building blocks for advanced nanostructured materials with desired catalytic, magnetic, and electronic properties. However, determining the structure of doped atomic clusters encounters many difficulties. A powerful approach to assign the ground state geometries of atomic clusters has been the comparison the recorded vibrational infrared spectra with the corresponding computed ones. In this work, we theoretically investigate the vibrational infrared spectra of the ground-state structures of AgnCr (n=2-12) clusters using density functional theory (DFT) calculations. The results of the investigation are useful for in-depth studies on size growth as well as experiments for determining the cluster structures in the future.

The Role of Diastolic Dysfunction in the Diagnosis and Treatment of Shock: The Rapid Ultrasound for Shock and Hypotension Protocol with a Diastolic Parameter
Authors: YAMANOĞLU Adnan
Published: March 2022

Aim: Numerous bedside ultrasound protocols have been developed for the evaluation of critically ill patients with bedside ultrasound. The most widely known of these protocols is the "Rapid Ultrasound for Shock and Hypotension (RUSH)’’ protocol. Diastolic dysfunction is the cause of nearly half of left ventricular dysfunctions, but no ultrasound protocol includes diastolic dysfunction. The aim of this study is to evaluate the contribution of the addition of diastolic assessment to the RUSH protocol to the diagnosis and treatment of critically ill patients.

Material and Methods: This prospective, observational study was conducted in a tertiary training and research hospital emergency medicine clinic critical care area for 1 year. Non-traumatic non-pregnant adult patients with systolic blood pressure below 90 mmHg or shock index >1 with signs of circulatory disorder were included in the study. Complaints, clinical findings, and vital signs of all patients included in the study were recorded. With the primary evaluation of the patients, the RUSH protocol was applied, and the findings were recorded. All clinical, laboratory, imaging, and consultation procedures of the patients, as well as the type of shock and its treatment were planned. After the diagnosis of the patients, a second cardiac ultrasound was performed maximum 2 hours later, and diastolic parameters were evaluated and recorded. Whether there was a difference between the diagnoses and treatments of the patients before and after the diastolic parameters were measured, was compared with McNemar and paired T test.

Results: A total of 69 patients with a mean age of 67 ± 13 years were included in the study, 54% of whom were females. Before the diastolic parameters of the patients were evaluated, distributive shock was detected in 20.3%, hypovolemic shock in 18.8%, obstructive-type shock in 8.7% and mixed type shock in 40.6% of the patients and their treatment was arranged accordingly. After evaluating the diastolic dysfunction parameters, distributive shock was found in 15.9% of the patients, hypovolemic shock in 18.8%, obstructive-type shock in 5.7% and mixed type shock in 47.8%. However, this change in diagnoses was not statistically significant (p=0.135). On the other hand, the treatment plans were changed in a total of 13 patients by re-adjusting the volume status due to the determination of the diastolic parameter in those patients, and the change was statistically significant (p<0.001).

Conclusion: Evaluation of the diastolic parameters may not be necessary in determining the shock type in patients with shock. However, the evaluation of the diastolic parameters is effective in adjusting the treatment and volume status of critically ill patients and may need to be evaluated as soon as possible.

Research in recent years has demonstrated complex Neanderthal activity, comparable to that of anatomically modern humans, in the context of bone tool production, pigments, adhesive compositions and non-utilitarian activities. The most numerous and widespread bone tools in Eurasian and African Middle Paleolithic are retouchers, which have been investigated for more than a century. The paper discusses various research approaches to the study of bone retouchers and the scientific results obtained throughout the history of the study of these tools. Traditionally, retouchers have been perceived by researchers as informal, situationally applied tools for retouching, or shaping various stone tools. Nevertheless, the scientific results obtained in the study of retouchers demonstrate the possibilities of their interpretation as formal tools and often link them to possible ritual activities, including the practice of cannibalism.
Nomological Explanation of the Formation of Social Norms in Anthropogenesis: a Trial
Authors:   The Institute for Philosophy and Law, Siberian Branch of the Russian Academy of Sciences, Rozov Nikolai
Published: March 2022

The paper is devoted to conditions for the appearance of the first social norms (rules of behavior, including prescriptions and prohibitions) in the groups of early hominids, presumably by 3—2.5 million years ago. The author uses theoretical ideas about objective group concerns and the structures that support them, about normativity as a multi-component social phenomenon, about the ritual mechanism of attitudes formation, about interiorization, as well as modern ideas about the nature of life and social interactions of ancient hominids, based on the data of archeology and paleoclimatology. To explain the normativity, the classical scheme of the nomological explanation of Carl Hempel is used. This approach has been expanded, since justification is required not only by an empirical hypothesis about the specific conditions for the occurrence of a phenomenon in a certain space and time, but also by the theoretical (“universal” in Hempel’s terms) hypothesis itself. It is shown that this approach opens opportunities for conducting a variety of studies with observations, field and computer experiments, as well as a methodological integration of already conducted studies of this kind, which are especially actively used in dealing with the origin of language problem.

EFFICACY OF LIVE ATTENUATED FOWL ADENOVIRUS SEROTYPE 8B ISOLATE OF MALAYSIA IN SPECIFIC PATHOGEN-FREE CHICKENS
Authors: MOHAMED SOHAIMI NORFITRIAH , BEJO MOHD HAIR
Published: March 2022

Fowl adenovirus (FAdV) is the primary agent of inclusion body hepatitis (IBH) in poultry and caused serious economic impact due to high mortality and poor productivity. To date, clinical cases of IBH in chickens increases over the years in Malaysia, thus, an effective local vaccine to control the disease outbreak is in dire need. The objective of the study was to determine the efficacy of live attenuated FAdV serotype 8b isolate, UPM1137CEL35, in specific-pathogen-free chickens. Attenuated isolate UPM1137CEL35 conferred full protection against the virulent FAdV isolate, UPM11134 in the vaccinated chickens. Neither clinical signs nor mortality were recorded in all vaccinated groups. However, in the challenged unvaccinated group, chickens showed clinical signs of weakness, reduced feed consumption, and lateral recumbency at day 4 to 7 postchallenge. Additionally, the body weight was low significantly (p<0.05) compared to the challenged vaccinated groups. Upon necropsy, the liver from the challenged unvaccinated group was pale at peripheral bilateral lobes with the presence of focal lymphoid aggregation microscopically, while, challenged vaccinated groups were normal without significant changes. All vaccinated chickens were protected from disease manifestations with antibody response compared to the challenged unvaccinated group. It was concluded that the attenuated FAdV isolate, UPM1137CEL35, has a high potential to be used as a vaccine against the FAdV serotype 8b of Malaysian isolates.

Published: March 2022

The study was aimed to determine the effects of adding milk, sugar and sweeteners to the total phenolic content and antioxidant activity of Camellia Sinensis (green tea) powder. Six green tea samples were brewed in cold water and whisked: Green tea powder (G), green tea powder with sugar (GS), green tea powder with aspartame (GA), green tea powder with milk (GM), green tea powder with milk and sugar (GMS) and green tea powder with milk and aspartame (GMA). The total phenolic content of green tea powder samples was evaluated by using Folin-Ciocalteu assay while α,α-diphenyl-2-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays were used to measure the antioxidant activity. Results showed that milk addition significantly enhanced by 59.84% of total phenolic content and also increased 26.3% (DPPH) and 42.35% (FRAP) of antioxidant activity of green tea powder, as compared to green tea samples without milk (p<0.05). Strong and positive correlations were found between the total phenolic content and antioxidant activity of green tea powder by using DPPH (r=0.990) and FRAP assays (r=0.997). In conclusion, it might be beneficial when milk is added to green tea as it could help to increase its antioxidant properties.

Field experiments were conducted in the rice fields of the Malaysian Agricultural Research and Development Institute in 2018 and 2019, to determine the efficacy of two commercial premix herbicides consisting of imazapic and imazapyr at 70:30 (formulation 1) and 30:70 (formulation 2) applied singly or in sequence for control of weedy rice and other rice weeds. Formulation 1 was applied as PRE at the 0 to 1-leaf stage of weedy rice while formulation 2 was applied as POST at the 3 to 4-leaf stage of weedy rice. Formulation 1 applied PRE at 150 g ai ha-1 with or without sequential application of formulation 2 applied POST at 75 or 150 g ai ha-1 provided complete inhibition of weedy rice. The same rate of formulation 1 applied PRE highly reduced weed density and dry weight of Monochoria vaginalis (99%) and Fimbristylis quinquangularis (93%) as compared to weedy check plots. Formulation 2 applied POST at 150 g ai ha-1 providing lower weed density and dry weight reduction of weedy rice (59 to 65%), M. vaginalis (80 to 81%), and F. quinquangularis (56 to 64%) as compared to those observed in formulation 1 applied PRE at 150 g ai ha-1. These results suggest that although formulations 1 and 2 share the same active ingredients, excellent control of weedy rice and rice weeds could only be achieved with PRE application of formulation 1 at 150 g ai ha-1.

Published: March 2022

The study was aimed to investigate the current status and threats of fisheries resources in the Kura River, Bangladesh. Monthly fish catch surveys were carried out from December 2015 to November 2016 in four catchment areas at Hasinarghat, Kandir-dor, Pulertol, and Barartok. In addition, questionnaire interviews and focus group discussions (FGD) were done to clarify perceptions about the Kura River fishery status. A total of 59 fish species from 22 families were documented and of which 27% were threatened. The values of diversity (H), richness (D), and evenness (J’) were calculated at 3.599, 4.345, and 0.921 respectively. The highest catch volume was recorded 19800±7722.71 kg in November 2016 at the Kandirdor and the lowest 225±110.65 kg in March 2016 at the Barartok (p<0.05). The upstream blockage (man-made dam) in the Kura River was identified as the main cause of fish habitat change, decrease fish biodiversity, and production of this River. Therefore, the findings of this study exposed that the conservation of fish has become urgent. In this regard, the baseline scenario of the Kura River biodiversity and threats will help to make awareness to take necessary conservation strategy as well as the need for further in-depth study.
MODELLING THE ENVIRONMENTAL AND BIOLOGICAL CUES FOR THE BLOOM OF SERGESTID SHRIMP Acetes (DECAPODA: SERGESTIDAE) IN COASTAL WATER OF MIRI, SARAWAK, MALAYSIAN BORNEO

Published: March 2022

The sergestid shrimp (Acetes spp.) shows the annual peak season from February to April. This krill-like shrimp, locally known as ‘bubok’, is one of the commercially important fisheries in Miri, Sarawak, Malaysian Borneo. Previous researchers had reported patchy data on the environmental factors and Acetes distribution in Miri-Bintulu adjacent areas. Moreover, insufficient analysis has led to the inability to conduct sustainable management strategies for Acetes fisheries. Therefore, this study is designed to explore the mathematical model usage to understand the interaction between selected water quality parameters and zooplankton assemblages with the Acetes population in the coastal water of Miri. Selected temporal biotic and abiotic data were collected using standard methods and later subjected to mathematical time series analysis called the Granger causality test. The results show bi-directional Granger causality between the abundance of Acetes and dissolved oxygen (DO). Interaction between other water quality parameters (temperature, salinity, turbidity, pH, TSS and Chlorophyll a) with the abundance of Acetes has also emerged. The number of zooplankton in the water column, namely Centropages, Euterpina, Oithona rigida, and Oncaea shows a significant causality towards the abundance of Acetes. The findings imply that complex interaction between biotic and abiotic factors exists during the bloom of Acetes in Miri; thus, relevant agencies should step up measures to ensure sustainable management of the coastal areas where Acetes bloom occurs.

Sleep deprivation has been shown to alter pain responses in humans and animals. The present study investigated whether the administration of Tualang honey in the rapid eye movement (REM) sleep deprivation rat model would modulate nociceptive responses with associated changes in the thalamus. Forty-eight Sprague Dawley male rats were randomised into four groups (n=12 for each group): control group (FMC), REM sleep deprivation (REMsd), REM sleep deprivation pretreated with Tualang Honey for 1 month (REMsdH) and tank control (TC). Following sleep deprivation for 72 hours, a formalin test was conducted and pain behaviour was recorded and analysed. The rats were sacrificed, and the brains were removed for histological examination and assessment of N-methyl-D-aspartate receptor (NMDA R2) level in the thalamus. REMsdH group showed a significantly lower level of pain behaviour score and NMDA R2 compared to the REMsd group (p<0.05). In addition, REMsdH also demonstrated a significantly higher number of Nissl stained neurons in comparison with the REMsd group (p<0.05). Furthermore, dark neurons, suggestive of neuronal damage, were observed in the REMsd group. In conclusion, administration of Tualang honey before REM sleep deprivation modulated nociceptive responses and prevent changes in thalamic neurons and NMDA R2 level.

Penelitian korelasi ini bertujuan untuk mengetahui hubungan konsentrasi peserta didik ekstrakurikuler bulu tangkis terhadap kemampuan smash. Populasi penelitian adalah seluruh peserta didik ekstrakurikuler di SMPN 5 Pamekasan dan SMP Plus Nurul Hikmah sebanyak 94 peserta didik (L: 60; P: 34). Pengambilan sampel menggunakan simple random sampling menghasilkan sebanyak 56 peserta didik (L: 28; P: 28). Konsentrasi peserta didik diukur menggunakan Concentration Grid Test (validitas, r=8,771) dan kemampuan smash diukur menggunakan Tes Kemampuan Smash (validitas, r= 0,926 dan reliabilitas, test-retest= 0,9). Hasil menunjukkan bahwa nilai rata-rata konsentrasi peserta didik sebesar 8,07 (konsentrasi kurang) dan nilai rata-rata kemampuan smash sebesar 48,86 (smash sedang). Uji normalitas menunjukkan bahwa distribusi konsentrasi peserta didik tidak normal (p= 0,0006<0,05) dan kemampuan smash normal (p= 0,2>0,05). Korelasi Spearman rho menunjukkan bahwa tidak hubungan antara konsentrasi peserta didik dan kemampuan smash (r= 0,146, p= 0,284>0,05). Tidak adanya hubungan dikarenakan kemampuan smash pserta didik masih kurang dan ketika melakukannya terlalu cepat, sehingga konsentrasi peserta didik yang harusnya dapat di maksimalkan dengan baik menjadi kurang baik atau kurang maksimal. Dapat disimpulkan penelitian tentang hubungan tingkat konsentrasi peserta didik terhadap kemampuan smash ekstrakurikuler bulu tangkis tidak ada hubungan.

BACKGROUND: The barbers’ work is associated to many infectious diseases which lead to major cause of morbidity and mortality in human’s population globally. This study aimed to determine barbers’ practices and health hazards associated with their profession in Fiji.

MATERIALS & METHODS: A cross sectional quantitative study was conducted to collect data from 50 observational sessions among barbers in Suva, Fiji in 2020. A sample of 25 barbers were randomly selected to participate in this study. A checklist was used to record and collect data. Out of the 25 barbershops observed none of them carried out any form of sterilization.

RESULTS: Only 4 (16%) did some form of disinfection with home bleach and savalon randomly while 84% did not have any form of decontamination in place. The results further illustrate that 22 (88%) of the disinfection were not potent while 3 (12%) were unknown. Similarly, 22 (88%) had inappropriate methods of disinfection and 3 (12%) were questionable. None of the barbershops observed had supply of hot water and only 15 (60%) had sufficient privy and hand washing facilities. Furthermore, only 6 (24%) used PPEs compared to 19 (76%) were in non-compliance.

CONCLUSION: This finding calls for immediate attention of authorities to enforce relevant laws and create awareness and training to improve standards in barbering profession.

This paper describes the management of facilities and infrastructure in Islamic educational institutions. This discourse is important to describe because the education system is an interrelated component such as curriculum, materials, methods, educators, students, facilities, tools, approaches and so on. So far, the understanding of the concept of integration and interconnection between the sub-systems above is still lacking so that the learning process is not optimal. This study uses a library research method with an analytical-descriptive approach. The results of the study indicate that the management of educational facilities and infrastructure is a collaborative process for the effective use of all educational facilities and infrastructure. The purpose of managing school facilities and infrastructure is to provide professional services so that the learning process can take place effectively and efficiently. The management process of Islamic education facilities and infrastructure includes (1) Planning of Islamic education facilities and infrastructure (2) Procurement of Islamic education facilities and infrastructure (3) Inventory of Islamic education facilities and infrastructure (4) Supervision and maintenance of Islamic education facilities and infrastructure (5) Elimination school facilities and infrastructure. The conclusion of this study is that the management of facilities and infrastructure in Islamic educational institutions must be oriented to the principles of being on time, on target and effective.
