Effect of the magnetically induced dichroism on the distribution of atomic polarization in Cesium vapor cells
Authors: Ghashghaei Fahime , Rashedi Alireza , Sarreshtedari Farrokh , Sabooni Mahmood 
Published: July 2020

Abstract
Distribution of the atomic polarization in a Cesium vapor cell, induced by optical pumping, is analytically calculated and discussed when an external magnetic field interacts with the system. Based on the rate equations of the optically pumped atomic system and considering the effect of magnetically induced dichroism on the absorption of polarized propagating light, we have obtained the light intensity and atomic polarization distribution along the propagation direction of the gas cell. It is shown that based on the initial light polarization and the laser detuning, the external magnetic field considerably changes the polarization distribution. The obtained results of the polarization distribution versus applied magnetic field can be used for different investigations, including the study of the atomic magnetometer’s sensitivity.
Teaching multilingual literacy in Ugandan classrooms: The promise of the African Storybook
Authors: Norton Bonny , Tembe Juliet 
Published: July 2020

Abstract
For over a decade, the authors have worked collaboratively to better understand and address the challenges and possibilities of promoting multilingual literacy in Uganda, a country of over 44 million people where over 40 African languages are spoken and English is the official language. This article focuses on the diverse ways that teachers promote early literacy in large multilingual classrooms, and how the innovative African Storybook digital initiative might support primary school teachers in both rural and urban areas. We begin the article with a description of our collaborative work on the African Storybook (http://www.africanstorybook.org/) and one of its derivatives, Storybooks Uganda (https://global-asp.github.io/storybooks-uganda/). Then, drawing on a collaborative study of primary school classrooms in eastern Uganda, we analyze four common strategies that Ugandan teachers use to promote multilingual literacy in their classrooms: the use of the mother tongue as a resource; songs and multimodality; translanguaging; and linguistic strategies for classroom management. We follow this with a discussion of a 2015 teacher education workshop in eastern Uganda, which illustrates how the African Storybook can help support Ugandan teachers as they navigate the challenges of large classrooms. We conclude that the African Storybook has much promise for addressing the United Nations’ 2030 Sustainable Development Goals.
Die musikalische Ambivalenz in Kleists Die heilige Cäcilie oder die Gewalt der Musik: Urteil über den Katholizismus oder Hilfsmittel zur Glaubensfindung?
Authors: Tkotzyk Raphaela 
Published: July 2020

Abstract
Heinrich von Kleist’s attitude toward the Catholic Church has produced two major positions in modern German literature. On one hand, there are those who understand Kleist simply as a church critic; on the other hand, there are those who consider Kleist’s attitude – and his alleged Kantian crisis and departure from all scholars – as supportive towards the Church. Die heilige Cäcilie precisely exemplifies this debate, because, depending on the way one reads the narrative, the text can be interpreted as an endorsement or as a criticism of the Church. However, the text can be read quite differently for yet, a third, alternative understanding: the element of music involved in Die heilige Cäcilie undermines a concrete definition of its position as well as a concrete statement regarding Kleist’s religious creed. Thereby, it serves as a tool to help the reader to make decisions in terms of religious beliefs and doctrines.

Published: July 2020

Abstract
Curriculum mapping is the process of designing a multidimensional model of an educational programme for a complete, more transparent and better-integrated learning experience. Many universities worldwide are building or expanding their technical infrastructure to manage their curricula. Our aim was to deliver a synopsis of current practices and describe the focus of research interest in implementing curriculum mapping tools for medical education. As part of the Building Curriculum Infrastructure in Medical Education (BCIME) project, we conducted a state-of-the-art narrative review of the literature. A systematised search of the PubMed/MEDLINE database for the years 2013–2019 resulted in 352 abstracts, from which 23 full-text papers were included in the final review. From these, we extracted guidance on 12 key characteristics of curriculum mapping tools. The collected experiences formed four thematic categories: visualisations, text descriptions and analysis, the outcome-based approach and adaptability in curriculum mapping. As result of the review, we summarised topics regarding ways of: implementating new competency-based catalogues (like NKLM) in curriculum mapping software (e. g., using dynamic checklists), methods of streamlining the authoring process (e. g., by automatic detection and alignment of action verbs in learning objectives descriptions) and graphical forms of presenting curriculum data (e. g., network visualisations using automatic clustering of related parts of a curriculum based on similarities between textual descriptions). We expect further developments in text-mining methods and visual/learning analytics in curriculum mapping. The collected data informed the design of a new curriculum management system called EduPortfolio, which is currently being implemented by the BCIME project.
Neue Chancen für das kulturelle Erbe
Authors: Klimpel Paul 
Published: July 2020

Abstract
Kulturinstitutionen müssen zahlreiche rechtliche Hindernisse überwinden, um kulturelles Erbe Online zu präsentieren. Das Urheberrecht erweist sich häufig als ein kaum lösbares Problem, insbesondere bei Zeugnissen sozialer Bewegungen wie der Frauenbewegung oder der Friedensbewegung, die niemals kommerziell vermarktet wurden. Die Klärung des urheberrechtlichen Stauts jedes einzelnen Objekts ist bei Massendigitalisierung kaum möglich. Die DSM-Richtline der EU wird die Situation verbessern, wobei einiges von den Details der Umsetzung abhängt. Dies gilt insbesondere für die Rolle der Verwertungsgesellschaften.
Functions with Linear Price Elasticity for Forecasting Demand and Supply
Authors: Hajdinjak Melita 
Published: July 2020

Abstract
In theoretical demand and supply analyses, functions with constant price elasticity are still frequently used although price elasticity is known to change in response to price. We relax the assumption of constant price elasticity to linear price elasticity which allows us to model demand and supply that decreases or increases with price. Quantity functions with linear price elasticity have been used in economics before but only to a limited extent since they have not been sufficiently theoretically studied. This paper overcomes this gap by identifying and studying all possible functional forms with linear price elasticity as well as their inverses, actually plotted as demand and supply curves. We find that quantity (demanded or supplied) as a function of price with linear price elasticity is a product of an exponential and a power function of price, while the price as a function of quantity involves the Lambert W function. Hence, the class of functions with linear price elasticity is heterogeneous: it contains reversible and irreversible functional forms as well as convex and non-convex functional forms. The class’ heterogeneity provides several modelling and research opportunities.
Replication of left ventricular haemodynamics with a simple planar mitral valve model
Authors: Daub Anna , Kriegseis Jochen , Frohnapfel Bettina 
Published: July 2020

AbstractTools for the numerical prediction of haemodynamics in multi-disciplinary integrated heart simulations have to be based on computational models that can be solved with low computational effort and still provide physiological flow characteristics. In this context the mitral valve model is important since it strongly influences the flow kinematics, especially during the diastolic phase. In contrast to a 3D valve, a vastly simplified valve model in form of a simple diode is known to be unable to reproduce the characteristic vortex formation and unable to promote a proper ventricular washout. In the present study, an adaptation of the widely used simplest modelling approach for the mitral valve is employed and compared to a physiologically inspired 3D valve within the same ventricular geometry. The adapted approach shows enhanced vortex formation and an improved ventricular washout in comparison to the diode type model. It further shows a high potential in reproducing the main flow characteristics and related particle residence times generated by a 3D valve.

Abstract

Objectives
Young laboratory medicine professionals (YLMPs) are the future of clinical laboratories. Although everyday practice shows significant differences among countries, especially during residency training, most of them face the same challenges. Besides promoting scientific, professional and clinical aspects of laboratory medicine in Europe, the European Federation of Clinical Chemistry and Laboratory Medicine (EFLM) should take into consideration YLMPs’ concerns and interests to help them achieve excellence. The aim of this survey was to assess the opinion and expectations of YLMPs about their involvement in the activities of EFLM.

Methods
An online survey was distributed to YLMPs in Europe through different channels. The questionnaire consisted of 21 items grouped into five sections: demographic questions, opinion about the current status of YLMPs within EFLM, YLMPs network, suggestions and opportunities, and scientific training and exchange. Where appropriate, responses from residents and specialists were compared.

Results
A total of 329 valid responses were obtained from 53 different countries. Countries with the highest number of participants were Spain, Turkey, Croatia and Romania. A significant percentage would like to know more about EFLM and their activities (86%) and wish EFLM promoted networking and scientific exchanges (95%), for instance by means of a European YLMPs network (93%). EFLMLabX project was widely unknown (75%).

Conclusions
YLMPs demand better connection to share concerns about daily healthcare duties, to keep updated and to advance professionally. EFLM needs to improve their advertising through national societies to increase YLMPs’ participation. In addition to international meetings and congresses, respondents have emphasized that workshops and other small group activities would significantly help promote laboratory medicine practice in Europe.
Playing by/with the rules: Creativity in language, games, and art
Authors: Cappelle Bert 
Published: July 2020

AbstractBergs and Kompa (Creativity within and outside the linguistic system.Cognitive Semiotics13. 1, 2020) discuss creativity in language, which they see as largely rule-bound, as opposed to ‘true,’ rule-breaking creativity in the arts. However, the distinction between intra- and extra-system creativity is not always easy to make. Languages have evolved into efficient systems for communication and occasionally allow for divergences of their own norms, within limits of comprehensibility, just like games are developed to enable maximum player creativity or even rule bending (as in the case of Monopoly Cheaters Edition). The paradox of systems licencing violations of their own norms and rules is similar to the one underlying avant-garde as one or moremovementsin the history of art, when breaking with expectations was the vogue of the time — hence, somehow to be expected. Judging art as innovative or not also depends on what we adopt as our artistic frame of reference. Furthermore, single works of art or single artists can be ahead of the times in some respects but not in others. Turning again to language, I agree with Bergs and Kompa that competent speakers abide by the rules, which implies such language users also know (perhaps not always fully consciously) how to exploit in-built mechanisms that make them sound creative.

Published: July 2020

AbstractThe day-to-day use of digital devices with Internet access, such as tablets and smartphones, has increased exponentially in recent years and this has had a consequent effect on the usage of the Internet and social media networks. When using social networks, people share personal data that is broadcast between users, which provides useful information for organizations. This means that characterizing users through their social media activity is an emerging research area in the field of Natural Language Processing (NLP) and this paper will present a review of how personality can be detected using online content.Approach A systematic literature review identified 30 papers published between 2007 and 2019, while particular inclusion and exclusion criteria were used to select the most relevant articles.Outcomes This review describes a variety of challenges and trends, as well as providing ideas for the direction of future research. In addition, personality trait identification and techniques were classified into different types, including deep learning, machine learning (ML) and semi-supervised/hybrid.Implications This paper’s outcomes will not only facilitate insight into the various personality types and models but will also provide knowledge about the relevant detection techniques.Novelty While prior studies have conducted literature reviews in the personality trait detection field, the systematic literature review in this paper provides specific answers to the proposed research questions. This is novel to this field as this particular type of study has not been conducted before.
On the domain of implicit functions in a projective limit setting without additional norm estimates
Authors: Magnot Jean-Pierre 
Published: July 2020

AbstractWe examine how implicit functions on ILB-Fréchet spaces can be obtained without metric or norm estimates which are classically assumed. We obtain implicit functions defined on a domain D which is not necessarily open, but which contains the unit open ball of a Banach space. The corresponding inverse function theorem is obtained, and we finish with an open question on the adequate (generalized) notion of differentiation, needed for the corresponding version of the Fröbenius theorem.

Authors: Shikh Evgenia , Zozina Vladlena , Kondratenko Svetlana , Melnikov Evgeny , Kukes Vladimir 
Published: July 2020

Abstract

Objectives
Coenzyme Q10 (CoQ10) has many vital functions in human body and its endogenous level can be affected either by various diseases or by administrated drugs. This study reveals the effect of atorvastatin, amlodipine and ethoxidol on the endogenous CoQ10 plasma concentration.

Methods
It was determined the total plasma concentration of endogenous CoQ10 in the plasma of 54 healthy individuals and 62 patients with cardiovascular diseases during treatment with various drugs using high performance liquid chromatography with mass spectrometric detection (HPLC-MS/MS).

Results
It was found that CoQ10 plasma concentration in patients is statistically significantly lower (on average −49.0 Δ%) than in practically healthy individuals. The total CoQ10 plasma level in patients receiving atorvastatin in the complex therapy is statistically significantly lower (−15.2 Δ%), and in patients taking amlodipine or ethoxidol is statistically significantly higher (+18.2 and +20.2 Δ%, respectively) than in patients of control groups (a group of patients who receive the same drugs, except for the studied one).

Conclusions
The study showed that in patients with CVDs treated with various drugs the CoQ10 plasma level is statistically significantly lower than in practically healthy individuals. So, to avoid the adverse reactions connected with low CoQ10 plasma levels, it is recommended to adjust the therapy to maintain its constant level.
Gain Scores, ANCOVA, and Propensity Matching Procedures for Evaluating Treatments in Education
Authors: Wright Daniel B. 
Published: July 2020

AbstractResearchers have several options available to analyze data from interventions when participants have not been randomly allocated into conditions. Among these are the gain score, ANCOVA, and propensity matching procedures. Each of these attempts to account for pre-treatment differences among the conditions, but they do so differently. These procedures are reviewed and methods for estimating them in R are shown. The choice of which of these procedures to use can be difficult. Different situations are shown where they perform differently. The primary conclusion of this paper is that models should be hypothesized for how the data may arise, data simulated for these models, and the properties of statistical procedures evaluated. A goal of this paper is to show these procedures without extensive mathematics in order to allow a broad read-ership to use these methods in their situations.
Experimental studies on the possibility of using a pulsed laser for spot welding of thin metallic foils
Authors: Sęk Piotr 
Published: July 2020

Abstract
The purpose of the experiment was to study the influence of the laser beam in pulse mode on metallic foils in order to obtain a spot weld. The welding process was carried out using the overlap weld method, using spot welds in various quantities. The Nd - YAG BLS 720 pulsed laser was used to conduct the experiment. The impact of the number of spot welds on the value of force needed to break the sample was examined. A number of measurements were carried out to determine the best process parameters. Butt welding and overlap welding were also performed using a continuous weld consisting of spot welds. Weld strength tests were performed to select the most appropriate parameters for the process under consideration.

Published: July 2020

Abstract
According to the concept of fire life cycle assessment (LCA), a new type of intumescent flame retardant was designed and synthesized by chemically bonding chitosan, phosphorus pentoxide and melamine. The resultant compound, chitosan ethoxyl melamine phosphate (CEMP), was characterized by FTIR, 1H NMR, 31P NMR, XRD and SEM. The performance of CEMP and organic montmorillonite (OMMT) was evaluated in the substrate of epoxy resin (EP) with limited oxygen index (LOI), UL-94, cone calorimetric test (CCT), TGA and TG-IR. As a result, intumescent flame retardant EP (EP3) containing 30.6% LOI and V-0 rating was prepared by adding 3 wt% OMMT and 15 wt% CEMP. The CCT results indicated that CEMP and OMMT reduced the peak of heat release rate (PHRR) to about one fourth that of pure EP and total heat release (THR), 1/2. Decomposition of EP and EP3 was traced from 100 to 600°C by TG-IR.

Published: July 2020

Abstract
The influence of density of amino groups, nanoparticles dimension and pH on the interaction between end-functionalized polymers and nanoparticles was extensively investigated in this study. PS–NH2 and H2N–PS–NH2 were prepared using reversible addition–fragmentation chain transfer polymerization and atom transfer radical polymerization. Zero-dimensional carbon dots with sulfonate groups, one-dimensional cellulose nanocrystals with sulfate groups and two-dimensional graphene with sulfonate groups in the aqueous phase were added into the toluene phase containing the aminated PS. The results indicate that aminated PS exhibited the strongest interfacial activity after compounding with sulfonated nanoparticles at a pH of 3. PS ended with two amino groups performed better in reducing the water/toluene interfacial tension than PS ended with only one amino group. The dimension of sulfonated nanoparticles also contributed significantly to the reduction in the water/toluene interfacial tension. The minimal interfacial tension was 4.49 mN/m after compounding PS–NH2 with sulfonated zero-dimensional carbon dots.

Published: July 2020

AbstractSituational factors may facilitate or frustrate the translation of entrepreneurial intentions into subsequent actions. In this study, we use data from two waves of a large-scale cross-country study of student entrepreneurship, the Global University Entrepreneurial Spirit Students' Survey (GUESSS), conducted in 2011 and 2013/2014 (n = 1434 students from 142 universities in nine countries), in order to investigate the impact of country-level institutions (financial market institutions and legal institutions) on the link between entrepreneurial intentions and subsequent start-up activities. We find that the quality of legal institutions has a significant positive impact on the translation of intentions into actions, whereas the quality of the national financial system does not influence the intentions-actions link. Theoretical and public policy implications are discussed.
The Combinations of Market and Non-Market Strategies That Facilitate Family Firm Survival
Authors: Basco Rodrigo , Rodríguez-Escudero Ana Isabel , Martin Cruz Natalia , Barros-Contreras Ismael 
Published: July 2020

Abstract
Even though family firms are characterized by an overlap between the family and business systems, family business research has focused separately on how family firms compete (i. e., strategic behavior) and how families are involved their firms (i. e., types of family orientation). With the aim of closing this research gap, we draw on the heterogeneity principle of family firms and the equifinality principle of the configurative approach to conjecture that family firms can successfully adjust their strategic behavior and family business orientation in a variety of ways to enhance their likelihood of survival. We follow a sample of Spanish family firms over an 11-year period (2004–2015) to test our model. Based on the Kaplan–Meier survival estimator and the Cox proportional hazard model, we find that survival likelihood is higher when firms combine a differentiation strategy with a business-first or a family-enterprise-first orientation or when firms follow a low-cost strategy with a family-first orientation.
