Guns and Butter: Stability and Robustness
Authors: Choi Gyoung-Gyu 
Published: May 2020

abstractThe paper considers the problem of allocating resources to economic goods and military goods (protecting property rights) in a contest model under an anarchic system which can be defined by the absence of a common superior authority to each state. I characterize the equilibrium and discuss its stability and robustness. The main finding is that if economic goods of the two states are complementary with Cobb-Douglas utility characteristics, the essential factor that affects a state’s resource allocation is its own maximum military level of production out of its resource endowment. In this sense, there is a unique stable equilibrium. This equilibrium is robust with the sequence of the states’ decisions insofar as the second mover’s observability is imperfect even slightly.
Model-predictive reference trajectory planning for redundant pneumatic collaborative robots
Authors: Mayer Annika , Müller Daniel , Raisch Adrian , Sawodny Oliver 
Published: May 2020

Abstract
Collaborative robots have the potential to simplify the working day of the future. The goal in the development of these robots is to assist human operators by handling all sorts of tasks. A common underlying problem is to move the robot’s tool center point in a desired way. In this work we consider the generation of a feasible trajectory in joint space given a reference in task space. This is done at the example of the Bionic Handling Assistant (BHA), a compliant, redundant and pneumatically driven continuum robot. The trajectory for the BHA is obtained using a model control loop (MCL) which internally realizes a nonlinear model predictive controller (NMPC). We simplify the high dimensional and nonlinear model of the BHA to a computational efficient model which still covers the major effects of the original dynamics. This results not only in a feasible trajectory but also enables the model control loop to be real-time applicable. The proposed method is validated in simulation.
Shadow Bank Run, Housing and Credit Market: The Story of a Recession
Authors: Ghiaie Hamed 
Published: May 2020

Abstract
This paper assesses the interaction between the housing and credit markets and shadow banks, with the possibility of bank runs. The findings illustrate how a negative TFP shock is amplified by macro-financial and macro-housing channels through household balance sheets, bank balance sheets, and liquidity channels. If the shock renders the shadow banking system insolvent, two equilibria coexist: the no-run equilibrium and the run equilibrium. In this instance, run is a sunspot coordination failure; if households receive a negative signal from fundamentals and stop rolling over deposits to the financial sector, banks are not able to fund their losses with new deposits. So they are forced to liquidate their assets at an endogenous fire sale price. The main finding of this paper is that the model with housing provides a comprehensive account of the consequences of economic crises, namely the house price double-dip, the output downward spiral, and the lengthy recovery period. To eliminate the bank-run equilibrium, this paper proposes macroprudential policy tools in the form of capital adequacy buffers and loan-to-value ratios. Then a welfare analysis is applied to determine the optimal policy mix.
Basic Income and Social Sustainability in Post-Growth Economies
Authors: Malmaeus Mikael , Alfredsson Eva , Birnbaum Simon 
Published: May 2020

AbstractA central task in efforts to identify pathways to ecologically and socially sustainable economies is to reduce inequality and poverty while reducing material consumption, which has recently inspired future post-growth scenarios. We build a model to explore the potential of a universal basic income (UBI) to serve these objectives. Starting from the observation that post-growth trajectories can take very different forms we analyze UBI in two scenarios advanced in the literature. Comparing UBI in a “local self-sufficiency” economy to a UBI in an “automation” economy, we show that although both scenarios satisfy central sustainability criteria, the impact of a UBI would differ greatly between these contexts. Our analysis shows that a UBI is less compatible with a labor-intensive local self-sufficiency economy than a capital-intensive, high tech economy. We conclude that the feasibility and attractiveness of a UBI in a post-growth scenario depends greatly on the specific characteristics of the economy.

Abstract
The aim of this study was to develop novel hydroxyapatite (HAP)-based bioactive bone replacement materials for segmental osteotomy reconstruction. Customized three-dimensional (3D) bone construct was manufactured from nanohydroxyapatite (nHAP) with poly(lactide-co-glycolide) (PLGA) coating using 3D models derived from the computed tomography (CT) scanning of the rabbit’s ulna and gradient 3D printing of the bone substitute mimicking the anatomical shape of the natural bone defect. Engineered construct revealed adequate micro-architectural design for successful bone regeneration having a total porosity of 64% and an average pore size of 256 μm. Radiography and micro-CT analysis depicted new bone apposition through the whole length of the reconstructed ulna with a small area of non-resorbed construct in the central area of defect. Histological analysis revealed new bone formation with both endochondral and endesmal type of ossification. Immunohistochemistry analysis depicted the presence of bone formation indicators – bone morphogenetic protein (BMP), osteocalcin (OCN) and osteopontin (OPN) within newly formed bone. Manufactured personalized construct acts as a “smart” responsive biomaterial capable of modulating the functionality and potential for the personalized bone reconstruction on a clinically relevant length scale.

Published: May 2020

Abstract

Objectives
Mucopolysaccharidosis type I (MPS I) was added to our expanded screening panel in 2015. Since then, 127,869 newborns were screened by measuring α-L-iduronidase (IDUA) enzyme activity with liquid chromatography tandem mass spectrometry (LC-MS/MS). High false positives due to frequent pseudodeficiency alleles prompted us to develop a second-tier test to quantify glycosaminoglycan (GAG) levels in dried blood spot (DBS).

Methods
Heparan-sulfate (HS) and dermatan-sulfate (DS) were measured with LC-MS/MS after methanolysis. DBSs were incubated with methanolic-HCl 3 N at 65 °C for 45 min. Chromatographic separation used an amide column with a gradient of acetonitrile and water with 10 mM ammonium acetate in a 9-min run. The method was validated for specificity, linearity, lower limit of quantification (LOQ), accuracy and precision.

Results
Intra- and inter-day coefficients of variation were <15% for both metabolites. Reference values in 40 healthy newborns were: HS mean 1.0 mg/L, 0–3.2; DS mean 1.5 mg/L, 0.5–2.7). The two confirmed newborn MPS I patients had elevated HS (4.9–10.4 mg/L, n.v. <3.2) and DS (7.4–8.8 mg/L, n.v. <2.7). Since its introduction in February 2019, the second-tier test reduced the recall rate from 0.046% to 0.006%. Among 127,869 specimens screened, the incidence was 1:63,935 live births. Both patients started enzyme replacement therapy (ERT) within 15 days of birth and one of them received allogenic hematopoietic stem cell transplantation (HSCT) at ht age of 6 months.

Conclusions
GAGs in DBS increased the specificity of newborn screening for MPS I by reducing false-positives due to heterozygosity or pseudodeficiency. Early diagnosis and therapeutical approach has improved the outcome of our patients with MPS I.
An Investigation of Chinese Undergraduates’ Ability to Translate Chinese Cultural Items into English and Predictors of Such Ability
Authors: Sun Haiyang , Gao Yuan 
Published: May 2020

AbstractCollege English teaching in China has long focused on importing cultures of English countries while neglecting to enhance students’ English competence in home culture. The present research aims to investigate Chinese non-English major undergraduates’ competence in translating Chinese cultural items into English and the significant predictors of such competence. With a test and a questionnaire as research instruments, this study was conducted to assess 82 undergraduates’ ability to translate three different levels of Chinese culture-specific items into English and explored the factors which might have affected the students’ home culture translation ability. The results show that the participants did well in translating the surface layer cultural items, but their performance in sub-surface and deep layer culture translation tasks was far from being satisfactory. It was also found that students had positive attitudes towards Chinese culture and were willing to learn to express Chinese culture in English, but their English learning motivation in general was not strong enough, and they were not given much input on Chinese culture in their English class. Students’ Chinese cultural knowledge and their awareness of the importance of learning Chinese culture in English were found to be the two significant factors that can predict their performance in the translation tasks. These findings have implications for the teaching of culture and cross-cultural communications in EFL classes.
Humor as an inroad to qualitative minority representation: The case of Taboe, a humorous human interest-program
Authors: Ridder Anouk De , Bulck Hilde Van Den , Vandebosch Heidi 
Published: May 2020

Abstract
One of the challenges Public Service Media institutions face today is how to translate normative values such as universality and diversity into measurable and tangible content in an attempt to realize their “public value”. This contribution shows how the communicative functions of humor can help create public value by introducing audiences to minorities. As a case in point, we analyzed Taboe, a humorous human-interest program about minorities including, amongst others, the visually impaired and the obese, broadcast by Flemish public broadcaster VRT in 2018. Based on in-depth interviews with program makers and participants and a qualitative content analysis of the program, the study found that humor provided the program with a positive, funny yet emotional tone of voice that attracted and kept the audience’s attention. By giving various minorities an active voice, Taboe introduced mainstream audiences to the their perspective, encouraging increased knowledge and understanding and, in turn, tolerance of, and acceptance towards, the minority groups represented.
Upset with the refugee policy: Exploring the relations between policy malaise, media use, trust in news media, and issue fatigue
Authors: Arlt Dorothee , Schumann Christina , Wolling Jens 
Published: May 2020

AbstractIn this paper, we introduce the concept of policy malaise, which refers to citizens’ dissatisfaction with the way political institutions and processes handle specific problems such as the refugee issue in Germany. Based on a representative online panel survey with two waves conducted in 2016 and 2017 (N = 836), we explore the occurrence of policy malaise among the German population and its relation to issue-specific media use, trust in news media, and issue fatigue. First, the results indicate that policy malaise toward the refugee issue is widespread in Germany. Second, we found that media use relates differentially to policy malaise: While high exposure to public broadcasting was negatively associated with policy malaise, we found the opposite for private broadcasting. Third, policy malaise is higher for people who experience issue fatigue and lower for people who trust the news media. Finally, trust in media reinforces the negative and positive relations between media use and policy malaise. Implications concerning the associations between policy malaise and political alienation in its broader sense are discussed.
Advertising in disguise? How disclosure and content features influence the effects of native advertising
Authors: Beckert Johannes , Koch Thomas , Viererbl Benno , Denner Nora , Peter Christina 
Published: May 2020

Abstract
Native advertising has recently become a prominent buzzword for advertisers and publishers alike. It describes advertising formats which closely adapt their form and style to the editorial environment they appear in, intending to hide the commercial character of these ads. In two experimental studies, we test how advertising disclosures in native ads on news websites affect recipients’ attitudes towards a promoted brand in a short and long-term perspective. In addition, we explore persuasion through certain content features (i. e., message sidedness and use of exemplars) and how they affect disclosure effects. Results show that disclosures increase perceived persuasive intent but do not necessarily decrease brand attitudes. However, disclosure effects do not persist over time and remain unaffected by content features.
“It is their job to make sure that the long-term vision for the show … stays intact”: Using insights from the television format industry to rethink the concept of media events
Authors: Skey Michael 
Published: May 2020

Abstract
The concept of media events continues to generate widespread debate among scholars around the globe. Studies that have challenged the concept’s functionalist foundations have undoubtedly sharpened our thinking. Conversely, approaches that have sought to expand the concept tend to confuse rather than clarify. In this paper, we argue that events that are planned, anticipated, and involve external organizations in their design demand a specific set of analytical tools. Furthermore, we draw a further distinction between one-off events and those that are cyclical in nature, with the latter being theorized using insights from studies of the television format industry. This approach not only focuses much needed attention on the production side of media events but also on the struggles between different interest groups (rights-holders, event hosts, media producers). We illustrate our arguments by drawing upon ethnographic material from the 2014 Eurovision Song Contest.
Deformations of rational curves in positive characteristic

Published: May 2020

AbstractWe study deformations of rational curves and their singularities in positive characteristic. We use this to prove that if a smooth and proper surface in positive characteristicpis dominated by a family of rational curves such that one member has all δ-invariants (resp. Jacobian numbers) strictly less than12⁢(p-1){\frac{1}{2}(p-1)}(resp.p), then the surface has negative Kodaira dimension. We also prove similar, but weaker results hold for higher-dimensional varieties. Moreover, we show by example that our result is in some sense optimal. On our way, we obtain a sufficient criterion in terms of Jacobian numbers for the normalization of a curve over an imperfect field to be smooth.

Published: May 2020

AbstractObjectivesSpina bifida manifests in various forms, and the clinical imaging findings depend on the level of the vertebral defect. It is difficult to predict the severity of the neurological symptoms and the degree of urgency of early treatment antenatally.Case presentationIn the present case report of fetal myelomeningocele (MMC), three-dimensional (3D) ultrasound showed accurate findings of fetal back surficial skin and tissue defect. The neonatologist and surgeons were able to decide upon appropriate treatment strategies on the basis of these findings.Conclusions3D ultrasound helps provide information to neonatologists and neurosurgeons about the initial treatment and illustrates the physical appearance of the disease for the parents of the unborn child.

Published: May 2020

Abstract

Background
According to a 2017 Centers for Disease Control and Prevention (CDC) report, there were 23.1 million Americans living with diagnosed diabetes. Diabetes-related complications in pregnancy are spontaneous abortion, preterm delivery, preeclampsia, fetal malformations, altered fetal growth, polyhydramnios, and unexplained fetal demise. Continuous insulin delivery through insulin pump is used for effective management of type 1 diabetes (T1DM).

Case presentation
We present case reports of four patients who were on insulin pump for at least 1 year prior to pregnancy and continued throughout their pregnancy. Although these case reports demonstrated overall good pregnancy outcomes, it did not show how well their blood glucose was controlled during pregnancy.

Conclusion
Standard of care in diabetic management during pregnancy using insulin pump in the presented case reports supports the American Association of Clinical Endocrinologists recommendation that insulin pump should be used for women with preexisting T1DM during pregnancy.

AbstractBackgroundWe describe a term neonate who was exposed to maternal mid-gestation infection withBabesia microtiand prenatal antimicrobic treatment with quinine, azithromycin, atovaquone, and clindamycin.Case descriptionThe neonate was born with a “blueberry muffin rash” and was diagnosed with extramedullary hematopoiesis (EHM) after ruling out congenital infection and malignancy. At 8 months of age, he presented with M5 acute myeloid leukemia (AML) with a t(8:16)(p11;13) translocation. This translocation is described in adult patients with treatment-related AML, suggesting sensitivity of the genome to extrinsic toxicity.ConclusionWe postulate that the biologic stress and treatment of maternal babesiosis played a role in the development of the rare form of AML seen in our patient.
Bounds on the discrepancy of linear recurring sequences over Galois rings
Authors: Vasin Anton R. 
Published: May 2020

AbstractWe study the discrepancy of linear recurring sequences over Galois rings. By means of an estimate of an exponential sum some nontrivial bounds on the discrepancy are derived. It is shown that these bounds are asymptotically not worse than known estimates for maximal period linear recurring sequences over prime fields.
An Anthropological Reimagining of Contract in Global Value Chains: The Governance of Corporate-community Relations in the Colombian Mining Sector
Authors: Knöpfel Laura D. 
Published: May 2020

Abstract
This contribution introduces an ant’s rather than a bird’s eye view on the legal institution global value chains (GVCs) have become. An ant’s view makes the abstract construct of the GVC tangible but at the same time reveals its unclear boundaries – where do GVCs begin and end? The article reflects on the role of contracts and contract law in the drawing and subsequent regulation of boundaries. It takes the reader into Colombia’s globalised natural resource sector where complex contractual constructs determine the relationships between firms, the state and local communities. These contractual constructs, together with the law, corporate codes of conduct and international standards that regulate them, create close and intertwined boundaries between the firm and its societal environment. In that closeness, the mining firm assumes and voices far-reaching responsibilities for the economic and social well-being of local communities. In regard to those corporate social responsibilities, contract law could and should play a pivotal role in the societal governance of GVCs.
Projecting the spread of COVID-19 for Germany
Authors: Donsimoni Jean Roch , Glawion René , Plachter Bodo , Wälde Klaus 
Published: May 2020

AbstractWe model the evolution of the number of individuals reported sick with COVID-19 in Germany. Our theoretical framework builds on a continuous time Markov chain with four states: healthy without infection, sick, healthy after recovery or despite infection but without symptoms, and deceased. Our quantitative solution matches the number of sick individuals up to the most recent observation and ends with a share of sick individuals following from infection rates and sickness probabilities. We employ this framework to study inter alia the expected peak of the number of sick individuals in Germany in a scenario without public regulation of social contacts. We also study the effects of public regulations. For all scenarios we report the expected end date of the CoV-2 epidemic.
Wood creep data collection and unbiased parameter identification of compliance functions
Authors: Tong Danyang , Brown Susan Alexis , Corr David , Cusatis Gianluca 
Published: May 2020

AbstractRising global emission have led to a renewed popularity of timber in building design, including timber-concrete tall buildings up to 18 stories. In spite of this surge in wood construction, there remains a gap in understanding of long-term structural behavior, particularly wood creep. Unlike concrete, code prescriptions for wood design are lacking in robust estimates for structural shortening. Models for wood creep have become increasingly necessary due to the potential for unforeseen shortening, especially with respect to differential shortening. These effects can have serious impacts as timber building heights continue to grow. This study lays the groundwork for wood compliance prediction models for use in timber design. A thorough review of wood creep studies was conducted and viable experimental results were compiled into a database. Studies were chosen based on correlation of experimental conditions with a realistic building environment. An unbiased parameter identification method, originally applied to concrete prediction models, was used to fit multiple compliance functions to each data curve. Based on individual curve fittings, statistical analysis was performed to determine the best fit function and average parameter values for the collective database. A power law trend in wood creep, with lognormal parameter distribution, was confirmed by the results.
