Pestpfeile, Miasma, Ansteckung
Authors: Leven Karl-Heinz 
Published: October 2021

Abstract
Epidemics were part of the ancient world; the Homeric Iliad begins with a pestilence that decisively shapes the further course of the plot. The sequence of historically attested epidemics ranges from the »Attic Plague« of 430 BCE to the »Antonine Plague« of the 2nd century to the pandemic of the »Justinianic Plague« of 541/42. Plagues are mentioned in numerous genera of ancient literature; in Hippocratic-Galenic medicine, the plague plays an important, yet peculiarly small role. The words »arrows of pestilence«, »miasma«, and »contagion« in the title stand for ancient theories of origin, which covered a wide range of metaphysicalreligious, natural history and empirical views and each conditioned different, also interacting, coping strategies of epidemics.

Daun kelor (Moringa oleifera) merupakan bagian tanaman yang mengandung nutrisi pendukung pertumbuhan tulang ekstremitas ayam jantan, meliputi protein dan mineral kalsium. Atas dasar potensi tersebut, dilakukan penelitian yang bertujuan untuk menganalisis pakan tambahan tepung daun kelor pada pertumbuhan tulang ekstremitas ayam jantan. Parameter uji penelitian ini meliputi panjang sayap, panjang tibiotarsus, panjang tarsometatarsus, panjang badan, dan panjang paruh. Penelitian menggunakan Rancangan Acak Lengkap (RAL) yang terdiri atas 5 perlakuan meliputi P0 (pakan standar 100%), P1, P2, P3 dan P4 berturut-turut mendapat tambahan tepung daun kelor 1%, 2%, 3%, dan 4% dengan pakan standar 99%, 98, 97%, dan 96%, tiap perlakuan diulang 3 kali. Data dianalisis menggunakan Analysis of Variance (ANOVA) dan uji lanjut Duncan Multi Range Test(DMRT) (P<0,05). Hasil penelitian didapatkan bahwa pemberian tepung daun kelor berpengaruh signifikan terhadap pertumbuhan panjang sayap dan panjang tarsometararsus, namun tidak berpengaruh signifikan terhadap pertumbuhan panjang tibiotarsus, panjang badan, dan panjang paruh. Kesimpulan dari penelitian ini adalah penambahan tepung daun kelor pada pakan berpotensi meningkatkan panjang tulang sayap dan tulang tarsometatarsus yang merupakan bagian dari tulang ekstremitas ayam jantan Moringa leaf (Moringa oleifera) is part of plant that contains nutrients that support rooster extremity bone growth, including protein and calcium minerals. Base on this potential, doing research to analyzing effect of supplemented Moringa meal on growth of rooster extremity bones. The test parameters of this study include wing length, tibiotarsus length, tarsometatarsus length, body length, and beak length. The research used completely randomized design (CRD) which consisted of 5 treatments including P0 (standard feed 100%), P1, P2, P3, and P4, respectively, received moringa leaf additions of 1%, 2%, 3%, and 4% with standard feed of 99%, 98, 97%, and 96%, each treatment was repeated 3 times. Data were analyzed using Analysis of Variance (ANOVA) and Duncan Multi Range Test (DMRT) advanced test (P <0.05). The results showed that supplementation of Moringa meal was significantly different (P<0.05) of the wing and tarsometatarsal length. However, it was not significantly different (P>0.05) in tibiotarsal length, body length, and beak length. Supplementation of Moringa leaf meal on the diet of rooster did not increase extremity bones at grower phase. The conclusion was addition of Moringa leaf meal in diet potentially increase wing and tarsometatarsal bone length which are part of rooster extremity bones.

A systematic review of pedagogical research on teaching Chinese as a foreign language in the United States – from 1960 to 2020
Authors: Zhang Shenglan 
Published: October 2021

Abstract
Since the 1960s, research on Chinese language teaching and learning has developed gradually, so it is worthwhile to synthesize the research results and examine trends and changes. A literature review shows that research has been done to synthesize research findings regarding Chinese language acquisition, but no review of the research studies have been done examining Chinese language pedagogy. This study investigates the research trends in Chinese language pedagogy in the U.S. by analyzing 122 empirical studies published in 25 peer-reviewed journals. These articles were identified through an exhaustive search using multiple databases and methods. The articles were cross analyzed in terms of research topics, language learning settings, methodological approaches, theoretical perspectives, and types of learners that were studied. The analysis found that the topics studied in pedagogical research have become increasingly diversified, and that many of the studies used SLA theories, cognitive theories, and multimedia theories as support for their research designs. Almost half of the studies used technology as part of their pedagogical method. The data also revealed that more research was done with beginning-level learners than advanced learners, and that most of the studies used qualitative data. Analysis of the data highlights the need for more research using Action Research and Design-Based Research methods and reveals a need for all future research to use theoretical support for the research designs. This article concludes by suggesting aspects of Chinese pedagogy that could benefit from further research.

“Bear in mind that”: Enhancing lecture comprehension through signaling importance markers
Authors: Kashiha Hadi 
Published: October 2021

Abstract
The present study attempts to propose a taxonomy for the discourse functions of importance markers in English academic lectures and examine their effects on ESL learners’ comprehension of important points in lectures. To this end, a corpus of 160 lecture transcripts from the BASE corpus was analyzed to identify and classify the main functions of words and expressions that mark importance in them. It was found that importance is indicated by the following lecture-specific devices and attributes: 1) student involvements, 2) topic announcers, 3) exam-related markers, 4) discourse clarifiers, 5) hedging markers, and 6) message promoters. A total of 62 Malaysian ESL students (38 females and 24 males) participated in this study and were divided into an experimental group and a control group, both of them of the same size. Through 12 forty-minute sessions of explicit instruction, the participants in the experimental group were instructed the discourse functions of importance markers in university lectures, whereas those in the control group did not receive such instruction. The result of the posttest of comprehension of important points indicated that familiarity with how importance is marked in lectures can boost ESL students’ understanding of main topics. The findings suggest that both novice lecturers and ESL/EFL students may profit from instruction as to how importance is indicated by native speaker lecturers through several lecture-specific discourse functions.

Markups and Concentration in the Context of Digitization: Evidence from German Manufacturing Industries
Authors: Weche John P. , Wagner Joachim 
Published: October 2021

Abstract
Recent empirical studies suggest that there is a rising trend of market power across sectors in advanced economies. We contribute to this line of research by providing industry-specific evidence for German manufacturing industries, based on representative high-quality firm-level data from official statistics that cover firms from all size classes with more than 20 employees (2005–2013). We compare firm-specific markups and industry concentration as market power indicators that reflect a market structure and a performance perspective, respectively. Our results do not suggest an overall average increase in market power in German manufacturing, but increasing markups and an increasing concentration in many industries. We demonstrate the complementarity of the indicators, as predicted by industrial organization theory. We also evaluate the competitive impact of digitization and find no clear evidence that digital transformation and market power go hand in hand.

Published: October 2021

Abstract
The rapid pace of development over the last few decades in the domain of machine learning mirrors the advances made in the field of quantum computing. It is natural to ask whether the conventional machine learning algorithms could be optimized using the present-day noisy intermediate-scale quantum technology. There are certain computational limitations while training a machine learning model on a classical computer. Using quantum computation, it is possible to surpass these limitations and carry out such calculations in an optimized manner. This study illustrates the working of the quantum support vector machine classification model which guarantees an exponential speed-up over its typical alternatives. This research uses the quantum SVM model to solve the classification task of a malignant breast cancer diagnosis. This study also demonstrates a comparative analysis of distinct forms of SVM algorithms concerning their time complexity and performances on standard evaluation metrics, namely accuracy, precision, recall, and F1-score, to exemplify the supremacy of quantum SVM over its conventional variants.
Correlating cognitive effort and noun role in spoken Japanese
Authors: Heffernan Kevin 
Published: October 2021

AbstractModels of language processing assume that the cognitive cost to integrate a noun with a verb depends on the distance between the noun and the verb. Such models predict that subjects require more cognitive effort than objects in SOV languages, such as Japanese. This study tests that prediction by investigating apparent cognitive effort differences in topic, nominative, accusative, dative, genitive, and predicative noun usage, using two corpora of spoken Japanese. A cognitive effort index score was determined for each text in the two corpora. The correlations between index scores and usage rates for each grammatical role were determined. Accusative, dative, and genitive noun usage significantly correlated with cognitive effort index scores, but topic, nominative, and predicate noun usage rates did not. These results suggest that the cognitive cost of noun integration depends not only on distance but also on the grammatical role of the noun.
Behavior of green reactive powder mortar reinforced with steel fibers
Authors: Dawood Eethar Thanon , Abdullah Mafaz Hani 
Published: October 2021

Abstract
The use of supplementary cementitious materials like crushed glass, steel slag, and silica fume at an acceptable level has resulted in many advantages such as reduction of the waste solid materials and production of eco-friendly material. Moreover, the inclusion of fibers for reinforcing cementitious matrix can improve its properties overall. Therefore, this research has been divided into two phases. The first phase has included the production of green reactive powder mortar and the investigation of its properties. The second phase has involved the incorporation of the micro steel fibers to green reactive powder mortar with different amounts. The results have indicated that the use of the crushed glass, steel slag, and silica fume by 8, 12, and 10% as a partial replacement of cement with suitable chemical admixture gives a great reduction of cement by 30% from the total cementitious amount used in reactive powder mortar and greater values of strengths for reactive powder mortar. The addition of micro steel fibers by 1, 1.5, 2, and 2.5% improves the dry bulk density, ultrasonic pulse velocity, compressive strength, flexural strength, and tensile strength of green mortar. The best increase has been observed at green reactive powder mortar (GRPC) containing 2 % of micro steel fibers.

Abstract
In Nigeria, sawdust is continuously generated in large quantities as waste but majorly under-utilised, a situation which causes serious environmental problems and health hazards when managed improperly. This work focussed on production and assessment of hygrothermal properties of solid core sandcrete blocks in which sand is partially replaced with sawdust at 0%, 10%, 20%, 30%, and 40% loading levels. Experiments were conducted on block samples made with untreated sawdust (USD) and on those similarly produced but with treated sawdust (TSD). The results showed that the blocks with USD content are capable of decreasing wall heat transmission load and improve energy efficiency of building envelopes better than their counterparts produced with TSD. In terms of compliance with standard bulk density and water absorption requirements, incorporation of USD or TSD at 20% or 10% level respectively, was found to be optimum for partial sand substitution in the studied block samples in order to suit the functional requirements of building structure and interior space. Since sawdust is cheaply and commonly available in vast amount, utilising it in sandcrete block production is a promising way of minimising its disposal problems while enhancing the development of safe, affordable, and sustainable housing.

Authors: Tamrakar Balram , Singh Krishna , Kumar Parvin 
Published: October 2021

Abstract
In this research article, the radio over fiber (RoF) Architecture using dual-parallel Mach–Zehnder modulator (DP-MZM) is analyzed and simulated. The nonlinearity is the main issues which degrade the performance of the RoF links. Using DP-MZM modulators, the nonlinearity can be reducing in the significant amount by controlling the bias voltages. The DP-MZM consists of two MZM modulators in parallel form with the variations of extinction ratio (ER). The proposed RoF link operated with single tone frequency signal at 10 GHz and the optical signal is transmitted further on Single mode optical fiber. The electrical spectrum at the output of photodetector confirms the quality of received signal while having desired and undesired terms. The proposed structure is designed using Optical Simulator simulation Software to confirm and validate the proposed results. The simulation output shows that the RF power of DP-MZM based RoF link has been found a decrement of 6.95 dB corresponding to undesired components with respect to desired RF signal for the increment in fiber length from 10 to 30 km. The digital transmission RoF link model is proposed and optimized for fiber impairments for 2–30 km, using 10 Gbps digital data string. electrical spectrum analyzer shows that very good eye openings for different fiber impairments, its shoes that proposed RoF model is optimized and having good SNR.

Authors: Ribeiro Rafael P. , Guerrero Filipe G. , Camargo Eduardo N. , Pivotto Luiza R. , Aimi Mateus A. , Loss Jefferson F. , Candotti Cláudia T. 
Published: October 2021

Abstract

Context
Sacroiliac dysfunction is characterized by a hypomobility of the range of motion of the joint, followed by a positional change regarding the relationship between the sacrum and the iliac. In general, the clinical tests that evaluate the sacroiliac joint (SIJ) and its dysfunctions lack validity and reliability values.

Objectives
This article aims to evaluate the construct validity and intra- and inter-rater reliability of the standing flexion test (STFT) and sitting flexion test (SIFT).

Methods
In this prospective study, the sample consisted of 30 individuals of both sexes, and the evaluation team was composed of five researchers. The evaluations took place on two different days: first day, inter-rater reliability and construct validity; and second day, intra-rater reliability. The reference standard for the construct validity was 3-dimensional measurements obtained utilizing the BTS SMART-DX system. For statistical analysis, the percentage (%) agreement and the kappa statistic (K) were utilized.

Results
The construct validity was determined for STFT (70% agreement; K=0.49; p<0.01) and SIFT (56.7% agreement; K=0.29; p<0.05). The intra-rater reliability was determined for STFT (66.3% agreement; K=0.43; p<0.01) and SIFT (56.7% agreement; K=0.38; p<0.01). The inter-rater reliability was determined for STFT (10% agreement; K=−0.02; p=0.825) and SIFT (13.3% agreement; K=0.01; p=0.836).

Conclusions
The STFT confirmed the construct validity and was reliable when applied by the same rater to healthy people, even if the rater had no experience. It was not possible to achieve minimum scores using the SIFT either for construct validity or reliability. We suggest that further studies be conducted to investigate the measurement properties of palpatory clinical tests for SIJ mobility, especially in symptomatic patients.
Masqueraders: how to identify atypical diabetes in primary care
Authors: Ahmed Sumera , Saeed Sana , Shubrook Jay H. 
Published: October 2021

Abstract
Diabetes mellitus is a complex set of conditions that impacts 34 million Americans. While type 1 diabetes, type 2 diabetes, and gestational diabetes are most frequently encountered, there are many other types of diabetes with which healthcare providers are less familiar. These atypical forms of diabetes make up nearly 10% of diabetes cases and can masquerade as type 1 or 2 diabetes mellitus (T1DM or T2DM), and the treatment may not be optimized if the diagnosis is not accurate. Atypical forms include monogenic diabetes (formally known as maturity-onset diabetes of the young [MODY]), latent autoimmune diabetes of the adult (LADA), ketosis-prone diabetes, and secondary diabetes. This paper will detail the defining characteristics of each atypical form and demonstrate how they can masquerade as type 1 or 2 diabetes mellitus. Gestational diabetes mellitus will not be discussed in this article.
International Economic Law Tribunals and Global Social Justice
Authors: J. Garcia Frank 
Published: October 2021

AbstractInternational courts play a key role in the attainment of global social justice objectives. The core contributions of international adjudication to global social justice are, not surprisingly, in line with the core functions of adjudication: the enforcement of substantive rights in a setting of fair procedures. Fully realizing the potential for justice inherent in this role is limited, however, by certain institutional and structural features unique to international adjudication. This article analyzes these opportunities, challenges, and background conditions in the context of international economic law (IEL) adjudication, where the results are mixed. For example, one can see in the case of the World Trade Organization (WTO) evidence of institutional and doctrinal evolution, albeit uneven, toward more substantively progressive outcomes. In the case of the foreign investment regime, however, one can see evidence of this regime retarding global social justice rather than advancing it. This makes it all the more important that all judges and arbitrators in IEL adjudications consider carefully the interpretive, remedial, and progressive roles that principles of justice can play in adjudication, particularly in the face of any deficiencies in procedural or substantive justice in the law or forum within which they operate. The work of IEL adjudication offers a number of possible sites for interpretive practices according to principles of justice, such as the resolution of disputes involves difficult interpretive questions centered around fairness and unfairness; equality and inequality of treatment; the scope of exceptions; and the meaning of evolutionary terms. Capitalizing on these opportunities and moving IEL adjudication toward global social justice requires what effective judging always requires: a vision of the goals of the institutions and regimes in question; an understanding of the social issues the regime either was created to address or touches incidentally through its actions and externalities; careful attention to the relationships among the relevant actors and their expectations; and a sophisticated understanding of the legal context and legislative history of the law in question.
