Authors: Milton Camille K. , O’Connor Kyle P. , Smitherman Adam D. , Conner Andrew K. , Martin Michael D.
Published: March 2020

Background:

Spinal osteochondromas are rare, benign tumors arising from the cartilaginous elements of the spine that may appear as solitary lesions versus multiple lesions in patients with hereditary multiple exostoses. Here, we present a 15-year-old female with a solitary C3-C4 osteochondroma who presented with a progressive quadriparesis and hand contracture successfully managed with a laminectomy/posterior spinal fusion.

Case Description:

A 15-year-old female presented with a 3-month history of progressive quadriparesis and hand contracture secondary to a magnetic resonance (MR) documented C3-C4 cervical spine osteochondroma. The MR imaging revealed a solitary osseous extramedullary outgrowth arising from the left laminar cortex of the C-3 vertebral body extending to C-4. Due to the marked resultant canal stenosis, the patient underwent a cervical laminectomy of C3- C4 with posterior spinal fusion. Gross total resection was achieved, and the pathology confirmed an osteochondroma. The patient’s myelopathy resolved, and 2 years later, she demonstrated no residual deficits or tumor recurrence.

Conclusion:

Here, we report the successful management of a 15-year-old female with a C3-C4 osteochondroma and progressive quadriparesis through cervical laminectomy/fusion.

Polypeptides Folding: Rules for the Calculation of the Backbone Dihedral Angles φ starting from the Amino Acid Sequence
Authors: Larocca Michele
Published: March 2020

Protein folding is strictly related to the determination of the backbone dihedral angles and depends on the information contained in the amino acid sequence as well as on the hydrophobic effect. To date, the type of information embedded in the amino acid sequence has not yet been revealed. The present study deals with these problematics and aims to furnish a possible explanation of the information contained in the amino acid sequence, showing and reporting rules to calculate the backbone dihedral angles φ. The study is based on the development of mechanical forces once specific chemical interactions are established among the side chain of the residues in a polypeptide chain. It aims to furnish a theoretical approach to predict backbone dihedral angles which, in the future, may be applied to computational developments focused on the prediction of polypeptide structures.
Identification of SARS-CoV-2 Cell Entry Inhibitors by Drug Repurposing Using in Silico Structure-Based Virtual Screening Approach
Authors: Choudhary Shweta , Malik Yashpal S. , Tomar Shailly
Published: March 2020

The rapidly spreading, highly contagious and pathogenic SARS-coronavirus 2 (SARS-CoV-2) associated Coronavirus Disease 2019 (COVID-19) has been declared as a pandemic by the World Health Organization (WHO). The novel 2019 SARS-CoV-2 enters the host cell by binding of the viral surface spike glycoprotein (S-protein) to angiotensin converting enzyme 2 (ACE2). The virus specific molecular interaction with the host cell represents a promising therapeutic target for identifying SARS-CoV-2 antiviral drugs. The repurposing of drugs can provide a rapid and potential cure towards exponentially expending COVID-19. Thereto, high-throughput virtual screening approach was used to investigate FDA approved LOPAC library drugs against both the S-protein and ACE2 host cell receptor. Primary screening identified a few promising drugs for both the targets, which were further analyzed in details by their binding energy, binding modes through molecular docking, dynamics and simulations. Evidently, Eptifibatide acetate, TNP, GNF5, GR 127935 hydrochloride hydrate and RS504393 were found binding to virus binding motifs of ACE2 receptor. Additionally, KT185, KT203 GSK1838705A, BMS195614, and RS504393 were identified to bind at the receptor binding site on the viral S-protein. These identified drug molecules may effectively assist in controlling the rapid spread of SARS-COV-2 by not only potentially inhibiting the virus at entry step but also as anti-inflammatory agents which could impart relief in lung injuries. Timely identification and determination of an effective drug to combat and tranquilize the COVID-19 global crisis is the utmost need of hour. Further, prompt in vivo testing to validate the anti-SARS-COV-2 inhibition by these drugs could save lives is justified.

Published: March 2020

The most rapid path to discovering treatment options for the novel coronavirus SARS-CoV-2 is to find existing medications that are active against the virus. We have focused on identifying repurposing candidates for the transmembrane serine protease family member II (TMPRSS2), which is critical for entry of coronaviruses into cells. Using known 3D structures of close homologs, we created seven homology models. We also identified a set of serine protease inhibitor drugs, generated several conformations of each, and docked them into our models. We used three known chemical (non-drug) inhibitors and one validated inhibitor of TMPRSS2 in MERS as benchmark compounds and found six compounds with predicted high binding affinity in the range of the known inhibitors. We also showed that a previously published weak inhibitor, Camostat, had a significantly lower binding score than our six compounds. All six compounds are anticoagulants with significant and potentially dangerous clinical effects and side effects. Nonetheless, if these compounds significantly inhibit SARS-CoV-2 infection, they could represent a potentially useful clinical tool.

Published: March 2020

Coronavirus disease COVID-19 is caused by the recently discovered corona virus that can spread between animals and humans. The outbreak of the corona virus was begun in Wuhan, China, in December 2019. The most common symptoms are fever, tiredness, and dry cough. Some individuals also develop aches and pains, nasal congestion, runny nose, sore throat, or diarrhea. It was reported that traditional remedies may alleviate the symptoms of COVID-19. Ayurveda is the world's oldest medical system that can manage any disease without side effects. Ayurveda is equipped with varieties of treatment modalities to handle with any type of deadly diseases. However, a major drawback is a lack of adequate scientific basis. Tulsi has multi-modal therapeutic effects, we hypothesize that tulsi may be effective in the prevention and management of COVID-19. Though the existing literature supports the management of symptoms of COVID-19 using tulsi, a lack of standard formulation limits its use. This is the need of time to start with translational research to provide scientific evidence for the efficacy and to establish the standard formulation of tulsi in the management of COVID-19.
Chemistry Education in Bosnia and Herzegovina
Authors: Zejnilagić-Hajrić Meliha , Nuić Ines
Published: March 2020

In this paper, the education system in Bosnia and Herzegovina is presented in the light of current state-level legislation, with an emphasis on chemistry education at the primary, secondary and tertiary level. The consequences of the last war in our country still persist and are visible in many aspects of everyday life, including the education system, thus limiting the efforts of education professionals to follow international trends in education. There are three valid curricula for primary education at the national level, each of which differs in the national group of school subjects. Teaching methods are common for all three curricula and are mainly teacher-oriented. The situation is similar with regard to secondary education. Study programmes at the university level are organised in accordance with the Bologna principles. The programmes are made by the universities themselves and approved by the corresponding ministry of education. Chemical education research in Bosnia and Herzegovina is mainly conducted at the University of Sarajevo. It deals with (1) the problems of experimental work in chemistry teaching, resulting in more than 60 experiments optimised for primary and secondary school, (2) integrating the knowledge of chemistry, physics and physical chemistry for university students, with regard to students’ difficulties observed during university courses and potential solutions, and (3) the effectiveness of web-based learning material in primary school chemistry for the integration of macroscopic and submicroscopic levels. For the purpose of this paper, official documents for primary, secondary and higher education have been used.

Published: March 2020

The first PhD thesis in the field of Chemistry Education at the Faculty of Sciences, University of Novi Sad, was defended in 1992. This can be regarded as the symbolic dawn of Chemistry Education as a scientific discipline in this region. After the official breakup of the Socialist Federal Republic of Yugoslavia, research that had started in the 1980s, and which was focused on the development of tools for assessing the quality and flexibility of student knowledge, was continued through the 1990s. This research included the application of computers to chemistry teaching, as well as the development of appropriate chemistry learning programmes. In the following period, research focused on the analysis of chemical teaching programmes in the Republic of Serbia, with a special emphasis on the possibility of including eco-chemical content in curricula. Accordingly, potentially efficient models were suggested. The most recent research has been focused on the investigation of the effectiveness of instructional strategies based on a systemic approach and a triplet model of content representation, using combined measures of students’ performance and mental effort. In this regard, tools for the efficient assessment of knowledge (systemic synthesis questions, context-based questions) have been developed along with tools for the efficient assessment of students’ misconceptions (multi-tier tests). Furthermore, in order to make teaching more effective, procedures for assessing the cognitive complexity of chemical problems have recently been developed and subsequently validated both statistically and by applying Knowledge Space Theory.
Evidence of the Development of Pedagogical Content Knowledge Related to Chemical Bonding during a Course for Preservice Chemistry Teachers
Authors: Vladušić Roko , Bucat Robert , Ožić Mia
Published: March 2020

The impression that many preservice chemistry teachers demonstrate issues in the application of their pedagogical content knowledge in teaching practice, especially in the area of fundamental chemistry topics, served as motivation for changes to the Chemistry Education 2 course curriculum. In order to stimulate pedagogical content knowledge, the course has been changed in the following areas: intending learning outcomes, the language of chemistry instruction, awareness of “Johnstone’s triangle” of operations, and common alternative conceptions. To obtain evidence of preservice teachers’ in-practice pedagogical content knowledge about chemical bonding, especially pedagogical content knowledge related to the revised areas of the Chemistry Education 2 course, we designed and conducted a case study based on detailed monitoring of one preservice teacher’s pre-teaching, teaching and teaching evaluation activities. The findings demonstrate evidence of growth of the preservice teacher’s pedagogical content knowledge of chemical bonding, with particular characteristics indicating that the source of this growth is almost certainly the revised Chemistry Education 2 curriculum.

This study aims to analyze the impact of diversification of exports on economic growth in the ASEAN. The sample used in this study is the eight member countries of ASEAN for the period 2006-2014. The dependent variable is the growth of income per capita, while the independent variable which is based on the theory of Solow growth include number of workers, total of investment and export diversification index. The Observations are estimated using pooled least square. Based on these results, the majority of ASEAN countries have positive relation between export diversification index and the growth of income per capita. At times of crisis, the export diversification index in the ASEAN is no longer a positive impact on national income which is shown by the negative coefficient on the dummy variable interaction between the global crisis of 2008 with an export diversification index.

On Marshallian theory of demand and short-run equilibrium
Authors: Icefield William
Published: March 2020

Mainstream neoclassical models lack genuine demand effects satisfying the principle of effective demand even with monopolistic competition, without addition of so-called frictions, such as inflexible price. There can only be demand shocks. Price is considered to be an independent variable, instead of quantity. But as Alfred Marshall original envisioned, we can instead think of quantity as an independent variable, along with associated equilibrium convergence via quantity adjustments. This allows us to consider a short-run market-clearing equilibrium with less demand than a long-run equilibrium, in contrast to mainstream models without frictions and shocks, with validation of the principle of effective demand.

Due to low therapeutic efficacy and severe adverse reaction of systemic administration for coronary heart disease (CHD) therapy, we designed a novel local target delivery system, called Active hydraulic ventricle support drug delivery system (ASD). This study was to investigate the potential advantages of ASD compared to intrapericardial (IPC) injection and factors that affected drug absorption through epicardium. After fluorescent dye, Cy5 was delivered respectively by ASD and IPC ways, with liposoluble, water-soluble Cy5, and viscous Cy5 solution injected by ASD, tissues were isolated from Sprague-Dawley (SD) rats and observed by in vivo imaging system. Then, atria and ventricles were taken for the paraffin section and observed under a fluorescence microscope. The results demonstrated that the fluorescence intensity of Cy5 injected by ASD distributed in the heart was significantly high than IPC injection. In contrast, the fluorescence signal in the ASD group spread in other tissues, such as lung, liver, spleen, and kidney, was much weaker. Moreover, when choosing liposoluble and viscous Cy5, the intensity of heart turn stronger and fluorescence dye distributed in other tissues was much less. Therefore, ASD applications may provide a promising drug delivery way for CHD. Furthermore, increasing solution viscosity and the liposoluble drug was beneficial to facilitate drug absorption through epicardium.

Published: March 2020

Municipal authorities have, among other tasks, a great interest in supporting their local economy. For this purpose, they provide consulting offices that advise companies and mediate cooperation partners. The city administration of Leipzig created a business register in which companies can provide their competences in free text fields. This business register contains over 1000 entries and it is not straight forward to find and compare companies based on their self-descriptions. In this paper, we propose a new visualization to analyze the distribution of local companies and exploring the competence profiles of the companies. In order to visualize connections between companies, we perform a semantic analysis. In detail, we use the management staff listing and the core competence descriptions to link the entries. The company location and the connections between the companies are visualized on a map or as a graph. The visualization provides several filtering and interaction mechanisms on demand. From a governance perspective, this leads to insights into company and industry sector networks within a local economic zone.

Having geographical proximity and a high volume of trade with China, the first country to record an outbreak of the new Coronavirus disease (COVID-19), Vietnam was expected to have a high risk of transmission. However, as of 4 April 2020, in comparison to attempts to containing the disease around the world, responses from Vietnam are seen as prompt and effective in protecting the interests of its citizens, with 239 confirmed cases and no fatalities. This study analyzes the situation in terms of Vietnam’s policy response, social media and science journalism. A self-made web crawl engine was used to scan and collect official media news related to COVID-19 between the beginning of January and April 4, yielding a comprehensive dataset of 14,952 news items. The findings shed light on how Vietnam—despite being under-resourced—has demonstrated political readiness to combat the emerging pandemic since the earliest days. Timely communication on any developments of the outbreak from the government and the media, combined with up-to-date research on the new virus by the Vietnamese science community, have altogether provided reliable sources of information. By emphasizing the need for immediate and genuine cooperation between government, civil society and private individuals, the case study offers valuable lessons for other nations concerning not only the concurrent fight against the COVID-19 pandemic but also the overall responses to a public health crisis.

Berbicara mengenai misi hal ini tidak terlepas dari kegiatan untuk menyebarluskan berita injil (kabar baik) dan ini juga adalah tugas lanjutan dari Yesus Kristus.
KASIH YANG MEMULIHKAN PERKATAAN
Authors: Latumahina Dina Elisabeth
Published: March 2020

Teks ini sebenarnya sangat mudah dipahami, karena sangat praktis, bersangkut paut dengan kehidupan kita sehari-hari, secara khusus mengenai kata-kata yang kita keluarkan setiap hari, tetapi sangat sulit untuk diterapkan. Menurut para ahli, setiap hari para wanita berbicara 20 ribu kata perhari, laki-laki hanya 7 ribu kata perhari. Sehingga wanita lebih banyak 13 ribu dari laki-laki. Saya masuk dalam 20 ribu kata perhari. Dan dari 20 ribu perhari itu, kata-kata yang dikeluarkan sangat bervariatif. Dan sudah pasti bahwa tidak semua positip, tidak semua yang baik, tidak semua yang benar, tidak semua yang membangun, tidak semua yang sedap didengar. Pasti ada yang negatip, ada saja yang tidak benar, ada gossip, ada fitnah, ada kemarahan yang tak terkontrol, ada dusta, ada perkataan yang berlebihan, ada kata-kata kotor, dsbnya. Jika kita berkata bahwa kita tidak pernah salah dalam perkataan, berarti kita sudah sempurna (ay.2). Malah kecenderungan manusia sekarang lebih senang, tertarik dengan gossip daripada mendengarkan kebenaran.
YOU RAISE ME UP

Waktu hidup Ayub kurang lebih 2000 tahun sebelum Tuhan Yesus. Dia belum juga mengenal Allah secara baik dan benar. Hanya dari kata orang dia mengenal YHWH. Tetapi dia mempuyai mempuyai iman yang luar biasa, yang mampu melihat pengharapan masa depan. Dia sudah mempuyai iman kepada penebus yang hidup (go’el) sekalipun melewati pergumulan yang sangat berat. Baca Ayub 19: 1-27 walaupun dia hidup di zaman yang sangat jauh dari Tuhan Yesus, iman Ayub sangat visioner. Dalam keadaan yang amat terpuruk, pergumulan yang sangat berat, masih ada setitik pengharapan bagi Ayub : Kutahu penebusku itu hidup (aku..aku tahu mukhalisku itu hidup). Bagi Ayub, penebus itu adalah kerabat dekat yang bersedia membela perkaranya, menebus hak-haknya yang hilang, mengeluarkan dia dari semua pergumulannya dan yang akan membangkitkannya/mengangkatnya dari pergumulannya.
REVIEW ARTIKEL TEOLOGI PERJANJIAN BARU
Authors: SUSANTI MIRA
Published: March 2020

salah satu bagian review ini adalah Paulus menjelaskan tentang perlengkapan senjata Allah yang mana Paulus ingin jemaat efesus melengkapi dirinya sebelum berperang. Paulus ingin meberitahukan pada jemaat bahwa gereja bukan sedang berjuang melawan manusia melainkan berjuang melawan pemerintah-pemerintah, melawan penguasa-penguasa, melawan penghulu-penghulu dunia yang gelap ini, melawan roh-roh jahat diudara
SALIB KRISTUS DAN PENGAMPUNAN

Published: March 2020

Ketika Tuhan Yesus mati di kayu salib, tidak ada satu budayapun di masa itu dari bangsa-bangsa sekitar Israel yang mempunyai pandangan yang positip tentang salib. Salib merupakan kejijikan, kengerian, kerendahan dan kebencian dalam kebudayaan Yunani, Romawi, maupun Yahudi.

Random feedback makes listeners tone-deaf
Authors: Vuvan Dominique T , Zendel Benjamin Rich , Peretz Isabelle
Published: March 2020

The mental representation of pitch structure (tonal knowledge) is a core component of musical experience and is learned implicitly through exposure to music. One theory of congenital amusia (tone deafness) posits that conscious access to tonal knowledge is disrupted, leading to a severe deficit of music cognition. We tested this idea by providing random performance feedback to neurotypical listeners while they listened to melodies for tonal incongruities and had their electrical brain activity monitored. The introduction of random feedback was associated with a reduction of accuracy and confidence, and a suppression of the late positive brain response usually elicited by conscious detection of a tonal violation. These effects mirror the behavioural and neurophysiological profile of amusia. In contrast, random feedback was associated with an increase in the amplitude of the early right anterior negativity, possibly due to heightened attention to the experimental task. This successful simulation of amusia in a normal brain highlights the key role of feedback in learning, and thereby provides a new avenue for the rehabilitation of learning disorders.
Variation in Respondent Speed and its Implications: Evidence from an Adaptive Testing Scenario

The more frequent collection of response time data is leading to an increased need for an understanding of how such data can be included in measurement models. Models for response time have been advanced, but relatively limited large-scale empirical investigations have been conducted. We take advantage of a large data set from the adaptive NWEA MAP Growth Reading Assessment to shed light on emergent features of response time behavior. We identify two behaviors in particular. The first, response acceleration, is a reduction in response time for responses that occur later in the assessment. We note that such reductions are heterogeneous as a function of estimated ability (lower ability estimates are associated with larger increases in acceleration) and that reductions in response time lead to lower accuracy relative to expectation for lower ability students. The second is within-person variation in the association between time usage and accuracy. Idiosyncratic within-person changes in response time have inconsistent implications for accuracy; in some cases additional response time predicts higher accuracy but in other cases additional response time predicts declines in accuracy. These findings have implications for models that incorporate response time and accuracy. Our approach may be useful in other studies of adaptive testing data.
Global food systems in the post-coronavirus era
Authors: Chiles Robert
Published: March 2020

Coronavirus is currently dealing a concussive blow to global food systems, but this crisis could also present a rare opportunity to uncover and address longstanding social and environmental problems. The purpose of this paper is to shed additional light on this rapidly developing situation by (i) outlining the vulnerabilities and inequities in the global food system that have been exposed by the coronavirus, (ii) identifying the emergent sociotechnical shifts that have occurred in the initial stages of the post-coronavirus era, and then (iii) interpreting these vulnerabilities, inequities, and shifts from the standpoint of two key theories in environmental sociology: the treadmill of production and ecological modernization.
Learning from Null Effects: A Bottom-Up Approach

A critical barrier to generating cumulative knowledge in political science and related disciplines is the inability of researchers to observe the results from the full set of research designs that scholars have conceptualized, implemented, and analyzed. For a variety of reasons, studies that produce null findings are especially likely to be unobserved, creating biases in publicly accessible research. While several approaches have been suggested to overcome this problem, none have yet proven adequate. We propose a new model in which scholars post short “null results reports” online that summarize their research designs, findings, and interpretations. We discuss a template for these reports and illustrate their utility with two experimental studies focused on the naturalization of immigrants in the United States and attitudes toward Syrian refugees in Jordan. We conclude with a discussion of how to overcome incentive problems and inculcate a discipline-wide norm of publicizing null findings.
Mapping inequalities in school attendance: the relationship between different dimensions of socioeconomic status and forms of school absence
Authors: Klein Markus , Sosu Edward , Dare Shadrach
Published: March 2020

In this paper, we investigated whether and to what extent dimensions of socioeconomic background (parental education, parental class, free school meal registration, housing status, and neighborhood deprivation) predict overall school absences and different reasons for missing school (truancy, sickness, family holidays and temporary exclusion) among 4,620 secondary pupils in Scotland. Participants were drawn from a sample of the Scottish Longitudinal Study comprising linked Census data and administrative school records. Using fractional logit models and logistic regressions, we found that all dimensions of socioeconomic background were uniquely linked to overall absences. Multiple measures of socioeconomic background were also associated with truancy, sickness-related absence and temporary exclusion. Social housing and parental education had the most pervasive effect across these forms of absenteeism.
Who’s writing Open Access (OA) articles? Characteristics of OA authors at Ph.D. granting institutions in the USA
Authors: Olejniczak Anthony J. , Wilson Molly J.
Published: March 2020

The open access (OA) publication movement aims to present research literature to the public at no cost and with no restrictions. While the democratization of access to scholarly literature is a primary focus of the movement, it remains unclear whether OA has uniformly democratized the corpus of freely available research, or whether authors who choose to publish in OA venues represent a particular subset of scholars - those with access to resources enabling them to afford article processing charges (APCs). We investigated the number of OA articles with article processing charges (APC OA) authored by 182,320 scholars with known demographic and institutional characteristics at American research universities across 11 broad fields of study. Results show, in general, that the likelihood for a scholar to author an APC OA article increases with male gender, employment at a prestigious institution (AAU member universities), association with a STEM discipline, greater federal research funding, and more advanced career stage (i.e., higher professorial rank). Participation in APC OA publishing appears to be skewed toward scholars with greater access to resources and job security.
