Geological-geomorphological characteristics and petrographical composition of the St. Anastasia Island
Authors: Dimitrov Dimitar , Banushev Banush 
Published: April 2021

Abstract
St. Anastasia Island is one of the symbols of the cultural and historical heritage of the Republic of Bulgaria. This raises the need for the study of risky oceanographic factors, climatic phenomena, risky geological processes as well as detailed petrographical characteristics of the Upper Cretaceous volcanic rocks forming the islands. The results of the petrographical study show that the island was built by Alkali feldspar trachytes. The volcanics from St. Anastasia Island shows a close petrochemical similarity to the volcanics from Alatepenski paleovolcano belonging to the “Peripheral Volcanic Centers” in the region.
To Kill a Mockingbird and Legal Ethics: On the Role of Atticus Finch’s Attic Rhetoric in Fulfillment of Duties to Client, to Court, to Society, and to Self
Authors: Kundmueller Michelle 
Published: April 2021

Abstract

Atticus Finch, protagonist of Harper Lee’s To Kill a Mockingbird and longtime hero of the American bar, is well known, but he is not well understood. This article unlocks the secret to his status as the most admired of fictional attorneys by demonstrating the role that his rhetoric plays in his exemplary fulfillment of the duties of an attorney to zealously represent clients, to serve as an officer of the court, and to act as a public citizen with a special responsibility for the quality of justice. Always using the simplest accurate wording, focusing on reason over emotion, and speaking in the same manner whether in private or in public, Atticus’s rhetoric exemplifies the ancient Roman style known by students of rhetoric as “Attic.” Using this style to navigate the potential for conflict among his duties, Atticus reveals the power, the elegance, and the ethical necessity of Attic rhetoric. Connecting Atticus’s name to the Attic style of rhetoric for the first time, this article advances several scholarly debates by demonstrating the mutual compatibility of the duties imposed by the Model Rules of Professional Conduct and proffering a powerful tool to attorneys seeking to practice or to teach improved ethical conduct.

Authors: Tripathy Laxminath , Tripathy Chita Ranjan 
Published: April 2021

Abstract
A new interconnection network topology called Hierarchical Hexagon HH(n) is proposed for massively parallel systems. The new network uses a hexagon as the primary building block and grows hierarchically. Our proposed network is shown to be superior to the star based and the hypercube networks, with respect to node degree, diameter, network cost, and fault tolerance. We thoroughly analyze different topological parameters of the proposed topology including fault tolerance routing and embedding Hamiltonian cycle.
An Effective e-Commerce Recommender System Based on Trust and Semantic Information
Authors: Shambour Qusai Y. , Turab Nidal M. , Adwan Omar Y. 
Published: April 2021

Abstract
Electronic commerce has been growing gradually over the last decade as a new driver of the retail industry. In fact, the growth of e-Commerce has caused a significant rise in the number of choices of products and services offered on the Internet. This is where recommender systems come into play by providing meaningful recommendations to consumers based on their needs and interests effectively. However, recommender systems are still vulnerable to the scenarios of sparse rating data and cold start users and items. To develop an effective e-Commerce recommender system that addresses these limitations, we propose a Trust-Semantic enhanced Multi-Criteria CF (TSeMCCF) approach that exploits the trust relations and multi-criteria ratings of users, and the semantic relations of items within the CF framework to achieve effective results when sufficient rating data are not available. The experimental results have shown that the proposed approach outperforms other benchmark recommendation approaches with regard to recommendation accuracy and coverage.

Published: April 2021

AbstractThe present article is a contrastive legal-linguistic study that deals with phraseologisms in criminal judgments of the German and Arabic legal systems. It aims primarily to determine legal phraseologisms that occur repeatedly in the same fixed form in German and Arabic criminal judgments and that have a specialized meaning. It focuses on the identification of types of such phraseologisms in the various components of criminal judgments. The aim is to find out which legal-linguistic phraseologisms are used in which parts of the texts of criminal judgments and what differences and similarities can be identified between the German and Arabic systems in this respect.
An Influence Prediction Model for Microblog Entries on Public Health Emergencies
Authors: An Lu , Yi Xingyue , Han Yuxin , Li Gang 
Published: April 2021

AbstractThis study aims at constructing a microblog influence prediction model and revealing how the user, time, and content features of microblog entries about public health emergencies affect the influence of microblog entries. Microblog entries about the Ebola outbreak are selected as data sets. The BM25 latent Dirichlet allocation model (LDA-BM25) is used to extract topics from the microblog entries. A microblog influence prediction model is proposed by using the random forest method. Results reveal that the proposed model can predict the influence of microblog entries about public health emergencies with a precision rate reaching 88.8%. The individual features that play a role in the influence of microblog entries, as well as their influence tendencies are also analyzed. The proposed microblog influence prediction model consists of user, time, and content features. It makes up the deficiency that content features are often ignored by other microblog influence prediction models. The roles of the three features in the influence of microblog entries are also discussed.

Authors: Baraniak Justyna , Kania-Dobrowolska Małgorzata 
Published: April 2021

Summary

Pelargonium sidoides DC is an interesting plant with various biological properties. Pharmaceutical companies and manufacturers of food supplements are particularly interested in its beneficial effects in upper respiratory tract infections. The search for new therapeutic options is especially important at a time when antibiotics are prescribed too often. However, due to proven clinical effects of extracts from Pelargonium sidoides, their use in diet supplements, especially intended for infants and small children, is highly disputable. The paper presents reports on the use of Pelargonium sidoides extracts in paediatrics and also tries to answer the question whether the pelargonium extract should be qualified as food supplement or medicine.

Published: April 2021

Abstract
Nanofluidic devices with two-dimensional nanochannels have many applications in biology and chemistry, however, it is still a challenge to develop a low-cost and simple method for fabricating nano-masks that can be used to produce two-dimensional nanochannels. In this paper, a novel low-cost and simple method, based on UV lithography and oxygen plasma, was proposed to fabricate nano-mask. The influence of exposure time on the photoresist mesas was investigated in the ultraviolet lithography process. The parameters of RF power and treatment time on the width reduction of photoresist mesas were analyzed by the oxygen plasma. In our work, in order to increase the efficiency controllability of photoresist removal, a RF power of 90 W, a pressure of oxygen plasma 60 Pa, and the time division method were adopted to remove photoresist by oxygen plasma. Finally, nano-patterns of photoresist mesas with bottom width of 330 nm were successfully fabricated. The proposed method provides a low-cost way to produce high-throughput two-dimensional nanochannels.

Published: April 2021

Abstract
Synthesis of thermochromic VO2 (M) was successfully done by annealing hydrothermally-prepared VO2 (B) at different temperatures and times. Conversion of the metastable VO2 (B) to the thermochromic VO2 polymorph was studied using thermogravimetric analyzer (TGA) under N2 atmosphere. Moreover, the phase and morphology of the synthesized samples were studied using X-ray diffraction (XRD) and field-emission scanning electron microscopy (FE-SEM), respectively. Accordingly, the XRD scans of all the annealed samples exhibited the presence of monoclinic VO2 (M), while the FE-SEM images of the samples showed the formation of nanorods and nanospheres, particularly those heated at high temperatures (650 °C and 700 °C). Meanwhile, differential scanning calorimetry (DSC) was used to measure the phase transition temperature (τc), hysteresis, and enthalpy of the prepared VO2. Based on these results, all samples displayed a τc of about 66 °C. However, the hysteresis was high for the samples annealed at lower temperatures (550 °C and 600 °C), while the enthalpy was very low for samples heated at lower annealing time (1.5 h and 1 h). These findings showed that crystallinity and nanostructure formation affected the thermochromic properties of the samples. In particular, the sample annealed at 650 °C showed better crystallinity and improved thermochromic behavior.

Published: April 2021

Abstract
This paper reports the synthesis and characterization of the Bi0:94Gd0:06FeO3 sample obtained by solid state reaction method. The structural and morphological analysis was performed by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Rietveld refinement analysis, confirming the obtaining of a rhombohedral crystalline phase and R3c space group (a = b = 5.577 Å and c = 13.847 Å), with an interconnected structure. Studies by X-ray photoelectron spectroscopy (XPS) revealed trivalent oxidation states of Bi, Fe and Gd ions. The synthesized sample exhibited a non-linear M–H loop indicating a weak ferromagnetic behavior with a remnant magnetization of 6.34 emu˙mol−1 and a coercive field of 295 Oe. The obtained structural and magnetic characteristics make these materials of great interest as multiferroic components.

Authors: Iversen Anette Sture 
Published: April 2021

Abstract
Dance as a cultural meeting point is a project that Dance in Schools, Norway, executed in three schools in Oslo during the spring of 2013, with funds from The Norwegian Directorate for Education and Training. The funding was to be given to projects that would, amongst other things, help schools reach curriculum objectives, increase the use of varied working methods, increase the pupils’ understanding of different cultural expressions and experience art. The project included a one-day workshop, a survey and reports from two observers. One class in three different schools got an introduction to Norwegian folk dance, hip hop, Bollywood and creative dance, and created and performed dances to each other in small groups. Dance in Schools’ aim was to gather information about the pupils’ knowledge of and experience with dance, contribute to increasing the pupils’ and teachers’ understanding of dance and how dance can stimulate learning, and social competence. The cultural meeting intended to be the meeting of dance forms and pupils from different cultures. The most important cultural meeting, however, turned out to be between the pedagogues’ dance culture and the pupils’ school culture.

Impact of a NICU parental engagement model of care on emergency room visits and hospital readmissions in preterm infants.
Authors: Fucile Sandra , Bates Amanda , Nagy Stephanie , Dow Kimberly 
Published: April 2021

Introduction
There is an increased occurrence of emergency room visits and hospital readmission in preterm infants compared to full-term infants after their initial hospital discharge.
Objectives
This study analyzes the effects of parental engagement programs, specifically the Family Integrated Model of Care (FiCare) on emergency room visits and hospital readmissions within the first 30 days after discharge from the NICU.
Methods
A retrospective cohort study was completed at the Kingston Health Sciences Centre (KHSC) and Quinte Health Care (QHC) Centre. The sample consisted of two groups of preterm infants born at or less than 33 weeks gestation: infants who participated in a parental engagement program (FiCare program), and those who were not involved in the FiCare program. Infants in both groups were matched for gestational age and birth weight (± 500 grams).
Results
A total of 73 infants (36 pre-FiCare, 37 FiCare) were enrolled in the study. Infants in the FiCare group had significantly fewer emergency room visits within the first 30-days post-discharge than the pre-FiCare group (7 vs 1 visits, p=0.025). There was a no significant reduction in the number of hospital admissions between the two groups.
Conclusion
Parental engagement programs have dual benefits of enhancing infant outcomes as well as serving as an effective method to reduce the number of emergency room visits in preterm infants after discharge from the NICU.
Ecosystem Carbon Fluxes Analyzed Using Eddy Covariance Technique
Authors: Routly Rachel 
Published: April 2021

Eddy covariance (EC) is an important measurement technique used in physical geography and atmospheric sciences to measure the exchange of carbon dioxide between an ecosystem and the atmosphere at a specific location. However, EC produces a net exchange of carbon dioxide yet research questions require an understanding of component fluxes, carbon dioxide uptake by plants through photosynthesis and carbon dioxide emissions due to plant and soil respiration. There are two major methods to partition EC measurements into these component fluxes: night-time and day-time partitioning methods. In the night-time method, nighttime measurements are used to estimate daytime respiration and calculate photosynthesis as a residual and in the daytime method, a light response curve is created to estimate daytime respiration and photosynthesis. This study investigates the benefits and drawbacks of these partitioning methods on two carbon dioxide exchange datasets from ecosystems in Canada.

The research sites were a) Mer Bleue, a peatland bog near Ottawa, Ontario and b) Cape Bounty, a high arctic tundra in Nunavut. By using a combination of the REddy-Proc software package, developed by the Max Planck Institute for Biogeochemistry, along with additional Matlab processing, the differences in photosynthesis and respiration due to partitioning methods are presented and discussed.
Changes in Knowledge Across Time

Published: April 2021

Our study focuses on children’s understanding of their own knowledge and how it changes over time. Preschool-aged children perform above chance when asked about current knowledge, but only children older than 5 years of age performed above chance for past, future, or intraindividual knowledge (Atance & Caza, 2018; Caza et al., 2016). However, we do not currently know whether awareness of past and future knowledge is related. While this type of awareness seems conceptually related to metacognition (the awareness of one’s own ignorance or knowledge; Rohwer et al., 2012), the relation to this skill is unknown. Thus, the goal of the current study is to investigate how children’s awareness of their own epistemic knowledge is related to their metacognitive abilities.
This study will explore children between the ages of 3.5- through 5-years-old, who will be assessed on their understanding of their current, past, and future knowledge, as well as other tasks assessing metacognitive skills. Further, we will explore the role of theory of mind and inhibitory control. We predict that children who do well on the epistemic knowledge task for the past will display better performance on the task asking about the future, and that both will be related to the other cognitive skills measured.
Due to the current global situation, we converted our study materials to an online format. Our poster will highlight this process and discuss ways to approach challenges in online developmental testing. Though data collection is ongoing, we present initial insight into the process, drawbacks, and benefits of online testing.
