Investigating the Effects of Interactive E-Book towards Academic Achievement
Authors: Lim Bibiana Chiu Yiong , Liu Llewellyn Wee Ling , Chian Hou Choo
Published: November 2020

Universities are trending towards electronic books (e-books) as instructional materials, displacing traditional printed books. The rapid acquisition of e-books has changed the way information is presented and one of the improvements is to make e-books interactive. However, there is an incomplete body of knowledge on how interactive e-books affect students, particularly in the learning of statistics. This paper aims to examine the effects of interactive e-books on academic achievement. This paper adopted an experimental approach to test the causal effect of two types of e-books, namely Traditional E-book (TE) and Interactive E-book (IE) on a sample of undergraduates enrolled in an introductory statistics unit. The experimental results indicated that students who learn statistics through IE produced higher scores in academic achievement than students who learn through TE. The findings of the study first extend the existing theory by showing that TE and IE can account for the variations in academic achievement. The study implied that e-books should not be static and e-book publishers and educators can choose to design their e-books using interactive formats with animation components depending on available resources. The study offers new insights on how academic achievement of students can be better managed through the design of e-book types.

Published: November 2020

The benefits of internationalization in higher education are indisputable. However, students studying abroad may face difficulties such as adjustment issues since they are away from home and go through a new stage in their lives. Seeing that an essential predictor of psychological adjustment is resilience, the current study aims to assess the role of a range of factors (optimism, social support, self-efficacy, psychological well-being, and demographic) in predicting the resilience of Indonesian students in Malaysia. Two hierarchical multiple regression analyses were used to test the influencing factors on resilience. Based on the literature, this study is quantitative in nature where a total of 229 Indonesian postgraduate students in Malaysian public universities were chosen as participants. Results showed that resilience is affected by optimism, social support, and self-efficacy. Essentially, this study provides practical insights into how international students can make adjustments to reduce the impact of stress faced in challenging situations.

Examining South Korean University Students’ Interactions with International Students
Authors: Rakushin Lee Andrea , Bailey Daniel Ryan
Published: November 2020

This mixed method case study examines South Korean university students’ interactions with international students. Data included a closed-ended survey, an open-ended survey, and a focus group. Participants comprised university students studying at a mid-sized university in central South Korea. Results indicate that students generally feel indifferent about interacting with international students and stated that communication barriers and lack of contributions of international students on assignments leads to less interaction. Quantitative data also reveals a lack of interest in interacting with international students. To improve interaction, students recommended providing more opportunities to communicate in the classroom and taking intercultural communication classes to increase understanding of diverse cultures. Additionally, students recommended sharing dorm rooms with international students, creating more social activities for interaction, and developing language, culture, and mentoring programs. Various practical and theoretical implications are discussed to help improve social interactions and increase intercultural communication on campus.

Authors: Abdul Aziz Mardiana , Omar Effat
Published: November 2020

Pyogenic granuloma-like Kaposi sarcoma (PGLKS) is an uncommon variant of Kaposi sarcoma (KS), which mimics benign pyogenic granuloma both clinically and histologically. We report a case of PGLKS of the toe occurring in a HIV-positive individual. It presented as a 2cm skin swelling of 2 weeks’ duration which was clinically felt to be a pyogenic granuloma. Histopathological examination revealed a polypoid atypical vascular lesion with overlying peripheral epidermal collarette. Spindle cell proliferation typically seen in KS was also identified, which was positive for human herpesvirus 8 (HHV8) by immunohistochemistry, confirming the diagnosis of PGLKS. Upon review of the literature, our case is the 29th case of PGLKS reported to date, and only the sixth in Asian population. Particular attention to histomorphology, and demonstration of HHV8 in lesional tissue will aid accurate diagnosis of this rare entity.

Besides being a natural antibiotic, the human cathelicidin LL37, produced by epithelial cells and neutrophils, is an important immune-modulator. LL37 alone, or in complex with DNA, can activate inflammatory pathways in psoriasis, Systemic Lupus Erythematosus (SLE) and Rheumatoid Arthritis (RA). In this work, we describe the capacity of the recombinant monoclonal antibody RB137, previously shown to specifically recognize LL37 in its native form by ELISA, to detect LL37 by immunofluorescence in human tissues derived from SLE and RA patients. In these tissues, LL37 decorates DNA filaments resembling neutrophil-extracellular-trap (NET) structures. This antibody represents a valuable tool to detect the presence, the native state and the exact localization of LL37 in human tissues in health and disease.

INTRODUCTION OF HIGHLY MORAL ASPECTS OF THE POLITICAL AND SOCIAL ORGANIZATION OF THE COUNTRIES OF THE EUROPEAN UNION IN THE NATIONAL SYSTEM OF INFLUENCE OF SOCIETY ON ACTIVITY OF LAW ENFORCEMENT
Authors:   Interregional Academy of Personnel Management, Kiva Ilya
Published: November 2020

The article considers the peculiarities of the introduction of high moral aspects of the political and social system of the European Union in the national system of public influence on the activities of law enforcement agencies. It is established that the implementation of legislative norms and provisions of the European Union in the legal system of Ukraine is the basis of the European course and further effective application of the principles of state regulation of law enforcement. It is substantiated that the activity of the police is subject to clear regulation both in the member states of the European Union and in Ukraine. Therefore, the organizational and legal support of public authorities in determining the procedure for recruitment, dismissal, receiving incentives for professional tasks corresponds to the principles of civil society. The public and its influence on law enforcement are correlated with law-centrism. It is noted that the influence of the community on the activities of law enforcement agencies is identified with respect for legal norms and regulatory framework. It is emphasized that decentralization, which is being introduced in the member states of the European Union, aims at equal distribution of powers between police bodies and, as a consequence, improvement of public law enforcement communication. In Ukraine, on the other hand, there are similar transformations in the legal framework of civil society cooperation with the police: the idea of decentralization corresponds to the Euro-Atlantic course, which is the guiding one, in the context of shaping state policy for Ukraine. It is pointed out that the process of perception by the police and structural units of law enforcement agencies of the European Union member states of the influence of civil society on the style of their functioning is a process of democratization of the socio-political system.
PECULIARITIES OF PUBLIC ADMINISTRATION MECHANISMS IN EMERGENCY SITUATIONS IN THE CONTEXT OF SOCIAL AND ECONOMIC SECURITY
Authors:   Academy of Personnel Management, Chornyj Oleg
Published: November 2020

The transitional stage of development of any society, including today's, involves the imbalance of most areas of social relations. As a result of the unresolved nature of a significant part of socio-economic issues, emergencies often arise, the stabilization of which requires extraordinary organizational measures that restrict certain freedoms of citizens. At the end of the XX century there was a huge number of disasters and catastrophes, epidemics are spreading around the world, at the same time the concept of emergency has not yet been fully defined. Depending on which situations are assessed as emergencies, how adequately regulated the grounds for their occurrence and regulated the order of impact in an emergency, the effectiveness of public administration in preventing and overcoming emergencies largely depends. Virtually every aspect related to the mechanisms of public administration in emergencies, one way or another has a way out on social issues. The importance of regulation is due to the complex nature of emergencies, the large number of bodies responsible for ensuring safety and empowering emergency decisions. In relation to emergencies, the formation of public administration tasks is determined by the fundamental characteristics of a developing society. This is achieved due to negative feedback, through which society is able to overcome harmful external influences, reduce the risk of destruction. In an emergency, there should be no appeal to the suddenness factor, as it is directly related to compliance and stability. Despite the fact that universal mechanisms of action in emergencies are defined, their regulation at the level of constitutional obligations is the main guarantee of overcoming the crisis situation and its consequences. The functional tool against possible abuses of administrative bodies and the powers granted to them serves as a means of protection and restoration of basic personal, socio-economic rights, freedoms and legitimate interests of citizens in emergencies. The use of emergency methods by public authorities is today an important tool of public administration, which determines the need and practical significance of the study of the peculiarities of state regulation in emergency situations. Restoration of normal living conditions and ensuring safety in emergencies is possible through comprehensive measures and the use of socio-economic and managerial tools.
Was erzählt Fritz Kreislers Geige?
Authors: Santi Matej
Published: November 2020

This short contribution shows the relevance of audiovisual sources for the history of 20th century music. It traces the role played by the violinist Fritz Kreisler (1875–1962) in shaping the widespread cliché of the “Viennese sound” via an examination of audiovisual sources. The sources stored in different online archives or social media portals play a key role, but the traceability of a given agent is not guaranteed. For this reason, controlled vocabularies and a digital tool which enable the addition of new metadata to already existing sources should be developed in the near future. This would enable researchers to trace agents, such as institutions and artists, and to connect them with places, repertoires and cultural topoi.
Alle Menschen werden Brüder?! Ein historisches Dokument aus dem Nationalsozialismus in den sozialen Medien
Authors: Berner Elias
Published: November 2020

This article deals with the recent emergence on social media of a particular kind of audiovisual sources from the time of National Socialism, namely extracts from a performance of the 9th Symphony that took place in 1942 at the ‘Berlin Philharmonie’ on Hitler‘s birthday. The concert was conducted by Wilhelm Furtwängler. In the footage, Joseph Goebbels can be seen in the applauding audience, before he congratulates the conductor with a handshake at the end of the concert. The material was filmed for propaganda purposes and used in a German News Reel in April 1942. Excerpts from the concert have, in varying lengths and usually without any context, been uploaded to YouTube by different users. This article examines these excerpts, revealing different layers of media within the collaged material. It then illustrates how the original propaganda material was also incorporated into documentary films after the war as part of a strategy to rehabilitate Furtwängler from his involvement with National Socialism. In the second part of the article, an analysis of user comments shows how the relationship between National Socialism, Furtwängler and the symbolism of the symphony is evaluated differently, and how these evaluations may be aligned with four political ideologies – each of which manifests a different understanding of the relationship between society and music.

Algorithmic automation of the complex music notation rules in MEI–XML through the example of the accidentals: The article demonstrates how music notation rules can be formalized into a computer algorithm. In particular, it handles the rule, whether the accidentals should be rendered or not when they repeat on the notes of the same pitch in the same measure. The decision process is described step-by-step while referring to the music notation rules. The algorithm was implemented in the XSLT-language for the needs of the Digital Interactive Mozart Edition and can be applied to MEI data. The tool can be downloaded from .

Single-atom metal (SA-M) catalysts with high dispersion of active metal sites allow maximum atomic utilization. However, conventional synthesis of SA-M catalysts involves high-temperature treatments, leading to a low yield with random distribution of atoms. Herein, a facile method to synthesize SA-M catalysts (M = Fe, Ir, Pt, Ru, Cu, or Pd) in a single step at ambient temperature, using the extracellular electron transfer capability of Geobacter sulfurreducens (GS), is presented. Interestingly, the SA-M is coordinated to three nitrogen (N) atoms adopting an MN3 on the surface of GS. Dry samples of SA-Ir@GS without further heat treatments show exceptionally high activity for OER when compared to benchmark IrO2 catalyst and comparable HER activity to commercial 10 wt.% Pt/C. The SA-Ir@GS electrocatalyst exhibits the best water‐splitting performance compared to other SA-M@GS, showing a low applied potential of 1.65 V to achieve 10 mA cm−2 in 1.0 M KOH solution with cycling over 5 h. The density functional calculations reveal that the large adsorption energy of H2O and moderate adsorption energies of reactants and reaction intermediates for SA-Ir@GS favorably improve its activity. This nature-based facile synthesis method of SA-M at room temperature provides a versatile platform for the preparation of other transition metal SA-M catalysts for various energy-related applications by merely altering the metal precursors.

The electroreduction of CO2 (CO2RR) is a promising strategy towards sustainable fuels. Cu is the only earth-abundant catalyst capable of CO2-to-hydrocarbons conversion; yet, its dynamic structure under operando CO2RR conditions remains unknown. Here, we track the Cu structure operando by electrochemical scanning tunneling microscopy and Raman spectroscopy. Surprisingly, polycrystalline Cu surfaces reconstruct forming Cu nanocuboids whose size can be controlled by the polarization potential and the time employed in their in-situ synthesis, without the assistance of organic surfactants and-or halide anions. If the Cu-surface is covered by a graphene monolayer, smaller features with enhanced catalytic activity for CO2RR can be prepared. The graphene protecting layer soften the 3D morphological changes that Cu-based catalysts suffer when exposed to aggressive electrochemical environments, and allows us to track the kinetic roughening process. This novel strategy is promising for improving Cu long-term stability and, consequently, controlling product selectivity.

Solubility screening is an essential, routine process that is often labour intensive. Robotic platforms have been developed to automate some aspects of the manual labour involved. However, many of the existing systems rely on traditional analytic techniques such as High Performance Liquid Chromatography or HPLC, which require pre-calibration for each compound and can be prohibitively expensive. In addition, automation is not typically end-to-end, requiring user intervention to move vials, establish analytical methods for each compound and interpret the raw data. We developed a closed-loop, flexible robotics system with integrated solid and liquid dosing capabilities that relies on computer vision and iterative feedback to successfully measure caffeine solubility in multiple solvents. After initial researcher input (<2 min), the system ran autonomously, screening five different solvent systems (20-80 min each). The resulting data matched values obtained using traditional manual techniques.

The design rules for materials are clear for applications with a single objective. For most applications, however, there are often multiple, sometimes competing objectives where there is no single best material, and the design rules change to finding the set of Pareto optimal materials. In this work, we introduce an active learning algorithm that directly uses the Pareto dominance relation to compute the set of Pareto optimal materials with desirable accuracy.

We apply our algorithm to de novo polymer design with a prohibitively large search space.Using molecular simulations, we compute key descriptors for dispersant applications and reduce the number of materials that need to be evaluated to reconstruct the Pareto front with a desired confidence by over 98% compared to random search.This work showcases how simulation and machine learning techniques can be coupled to discover materials within a design space that would be intractable using conventional screening approaches.
Importance of the Oxyl Character on the IrO2 Surface Dependent Catalytic Activity for the Oxygen Evolution Reaction

Published: November 2020

The oxygen evolution reaction (OER) is considered to be the limiting step for the water splitting process. OER catalyst optimization is hindered because in the desirable acidic conditions the sole active catalysts are the expensive RuO2 and IrO2-based materials. Thus, the understanding of the factors controlling the reactivity of IrO2 is mandatory. In this contribution, we carried out spin polarized DFT (PBE-D2) periodic calculations to analyze the catalytic activities of the main ((110), (011), (100) and (001)) IrO2 surfaces. We considered the oxo-coupling (I2M) and water nucleophilic attack (WNA) mechanisms and computed the energy barriers of the chemical processes. Results show that the oxo-coupling and the water attack should be viewed as homolytic couplings and thus, the two processes only occur if the Ir=O species on the surfaces exhibit oxyl character. In these cases, the WNA mechanism is always easy and it becomes the most favorable pathway on the (110), (100) and (001) surfaces. In contrast, for the (011) facet the oxo-coupling is preferred. The required overpotentials for the four IrO2 surfaces depends on the feasibility to oxidize the Ir-OH to Ir-O species. However, if the oxidation is too favorable the resulting Ir=O species has no oxyl character and thus it does not further react. Therefore, the optimal catalyst shows a trade-off between the Ir-OH oxidation feasibility and the oxyl character of the surface Ir=O species. These two factors are tuned by the coordination of the unsaturated iridium sites: the (100) and (001) surfaces are more active than the (110) and (011). The key role of oxyl species has been shown to be important for molecular catalysts. However, the implications of oxyl species on IrO2 have rarely been mentioned. Present results show that the homogeneous and heterogeneous processes seem to have important similarities, thus suggesting that strategies used in one of the two fields could be transferred to the other.

Nuclear magnetic resonance (NMR) spectroscopy is a well-established analytical technique used to study chemicals and their transformations. However, high-eld NMR spectroscopy necessitates advanced infrastructure and even cryogen-free benchtop NMR spectrometers cannot be readily assembled from commercially available components. We demonstrate construction of a portable zero-field NMR spectrometer employing a commercially available magnetometer and investigate its applications in analytical chemistry. In particular, J-spectra of small representative biomolecules [13C]-formic acid, [1-13C]-glycine, [2,3-13C]-fumarate, and [1-13C]-D-glucose were acquired and an approach relying on the presence of a transverse magnetic eld during the detection was investigated for relaxometry purposes. We found that water relaxation time strongly depends on the concentration of dissolved D-glucose in the range of 1-10 mM suggesting opportunities for indirect assessment of glucose concentration in aqueous solutions. Extending analytical capabilities of zero-field NMR to aqueous solutions of simple biomolecules (aminoacids, sugars and metabolites) and relaxation studies of aqueous solutions of glucose highlight the analytical potential of non-invasive and portable ZULF NMR sensors for applications outside of research laboratories.

Inflammation is the defence response of the body to any injury or any other external agent that causes damage to the human body. Over many years there had been a rising concern for the inflammation that is caused due to the physiological stress and strain in the body due to the oxidative free radicals and oxidative damage. Medicinal plants have been used as the best treatment alternatives for the diseases in various medical systems in India and around the world. The scientific proof and validation are not authentic to that desired level. In this regard, herbs have been investigated for their pharmacological properties based on the medicinal claims and folklore claims. They had been worked by numerous amounts of research where the claims had been proven correct and published with scientific evidence. The ointment was prepared using the extracts of the plant Salvia and the activity was attributed to the phytosterols, and by inhibiting the prostaglandin synthesis. The activity was comparable to the standard drug and the extracts and showed better activity. The activity exhibited by the ointment was very rapid and enhanced the healing of the paw edema, which was induced by carrageenan.
