Some inequalities and superposition operator in the space of regulated functions
Authors: Olszowy Leszek , Zając Tomasz 
Published: December 2019

Abstract
Some inequalities connected to measures of noncompactness in the space of regulated function R(J, E) were proved in the paper. The inequalities are analogous of well known estimations for Hausdorff measure and the space of continuous functions. Moreover two sufficient and necessary conditions that superposition operator (Nemytskii operator) can act from R(J, E) into R(J, E) are presented. Additionally, sufficient and necessary conditions that superposition operator Ff
: R(J, E) → R(J, E) was compact are given.
KIKS Creativity and Technology for All

Published: December 2019

Abstract
To help meet an educational and societal requirement for all students to enjoy, have confidence and ability in creativity and technology, the “Kids Inspiring Kids in STEAM” (KIKS) EU project adopted an intensive Hothousing process challenging students in Finland, Spain, Hungary and the United Kingdom to engage in collaborative problem solving to develop solutions to: “How would you get your schoolmates to LOVE STEAM?” The project provided a process and technology toolkit for students, including those with special educational needs, to achieve their solutions.
A completion rate of 90% suggested that all schools and students could cope with and enjoy the process and associated technology toolkit, which featured social media plus Micro:bit, Tracker and GeoGebra for data collection and modelling.
We have extended the toolkit with simulation software and a graphical programming environment to produce realistic animations of objects in motion. Thus students will have a creativity and technology toolkit to experience the kinds of techniques and skills used by software engineers in the video, games and special effects industries. The toolkit will be on the GeoGebra platform which, in addition to mathematics, embraces STEAM and social media.
Pathographies and Epiphanies: Communicating about Illness
Authors: Nesby Linda 
Published: December 2019

AbstractEpiphany is a literary device bringing forth an experience of sudden wisdom or insight and is particularly applied to literature from the romantic era. However, epiphanies are also present within contemporary autobiographical patient stories (pathographies) expressing something that is difficult and perhaps otherwise left unspoken. Kristian Gidlund’s pathographyI kroppen min. Resan mot livets slut och alltings början(2013) deals with the author’s experience of having severe cancer. Gidlund was a non-religious person but at the end of his life, his blogposts included epiphanies or visionary moments regarding his afterlife. In this article the author shows how the use of epiphanies can be a subtle means of expressing thoughts and feelings when facing severe illness. Knowing how to identify and interpret epiphanies in pathographies can improve the abilities of relatives and medical staff to communicate with patients about existential matters and emotional distress. KAKA I would like to thank Rachael Reynolds and Paul Farmer for their most conscientious proofreading, and Dr. Christopher Oscarson for the accurate translation of the quotes from Kristian Gidlund’s book.
“That’s (not) it”. Inger Christensen’s Det as Litanic Verse
Authors: Cymbrykiewicz Joanna , Zańko Aldona 
Published: December 2019

Abstract
Inger Christensen’s poem collection Det is one of the most recognizable and significant contemporary Danish works. Its complex and elaborate form and message have already been a subject of innumerous investigations and analyses, but neither of them has addressed its litanic traits. Basing on Witold Sadowski’s methodological apparatus, we intend to demonstrate that Christensen’s work can be perceived as litanic verse in terms of its form and generic worldview. As it appears from our investigation, in Det one litanic gene, the polyonymic, is most discernible, which translates into repetitive structures and enumerations, as well as the lyrical person’s humbleness in face of the greatness of creation.
Paris’ hjerte Johannes V. Jensen og rejsens erotik
Authors: Dam Anders Ehlers 
Published: December 2019

AbstractThis article highlights the link between travel and erotics as a literary trope, exemplified by Johannes V. Jensen’s story ”Louison” (1899). ”Louison” describes the short-lived affair between a male traveller and a loose woman. From their first encounter on a Parisian boulevard, loaded with baudelairian esthetics, to their sudden parting after a day and a night spent together, their relationship is made possible by the anonymity of the modern city and by the condition of modernity. The erotic encounter in Jensen’s story is inextricably connected — like in Baudelaire — to the modern urban backdrop against which it unfolds. In Jensen’s story, the erotics of travel feeds into the ”myth of Paris”: far from being merely the story of an erotic encounter, ”Louison” is also the vivid description of a fin-de-siècle Paris, swarming and buzzing with constant, multiple energies that unify in a totality elevated to the dimensions of ”myth” — a word charged with significance in Jensen’s work.
Erotikk og reise i traumatisk erindring. Madame Nielsens Det højeste væsen mellom myte og politikk
Authors: Langås Unni 
Published: December 2019

Abstract
In the Danish author-performer Claus Beck-Nielsen’s multi-artistic work the notion of the journey can be understood not only as a political and activist initiative, but also a configuration of movements that takes part in a continuous examination of identities and positions. His 2017 novel Det højeste væsen [The Highest Being], published under the name Madame Nielsen, demonstrates how his energetic activity and flamboyant performativity also imply an aesthetic confrontation with a traumatic past. The two plots — the failed love story and the falling dictator — reflect each other in their recycling of myths and clichés. By means of the concept of ‘postmemory’, I argue that the novel makes use of cultural conventions achieving neither an historically adequate representation nor a reparative one. The novel reveals the ways in which trauma works as an impossibility of experiencing and therefore also a distortion of memorizing processes. Both in the form of the historic events connected to the Romanian dictator and the narrator’s affair with the Romanian ballerina, powerful mediations end up substituting the experience and instead consolidating its traumatic memory.
Billing Codes Determine Lower Physician Income for Primary Care and Non-Procedural Specialties
Authors: Langer Arielle L. , Laugesen Miriam 
Published: December 2019

Abstract
The income gap between specialists and primary care physicians and among specialists is well established, but the drivers of this difference are not well delineated. Using the Community Tracking Study (CTS) Physician Survey, we sought to isolate and compare premiums paid to physicians for specialization and the proportion of time spent on offices visit rather than procedures. We divided medical subspecialties according the proportion of Medicare billing for Evaluation and Management (E&M) codes for the specialty as a whole. We report substantial differences in income across physician specialty, and over 70 percent of the difference in income remained controlling for factors that may confound the relationship between income and specialty including gender, location and type of practice, and hours. We note a large variation in premiums for specialization: 11.3–46.8 percent above family medicine after controlling for confounders. Classifying medical subspecialties by E&M billing as procedural versus non-procedural specialties revealed clear income differences. Controlling for confounders, procedural medical specialties earned 37.5 percent more than family medicine, as compared with 15.3 percent for non-procedural medical specialties. This analysis suggests that differences in physician income and resulting incentives are a direct consequence of the payment structure itself, rather than compensation for additional years of training or a reflection of different underlying demographics.
Numerical Investigations of a Passive Micromixer Based on Minkowski Fractal Principle
Authors: Chen Yao , Chen Xueye 
Published: December 2019

Abstract
This paper is mainly to study the mixing efficiency and pressure drop of the Minkowski fractal obstacle micromixers. The mixing efficiency of primary Minkowski fractal obstacle (PMFO) micromixer and secondary Minkowski fractal obstacle (SMFO) micromixer are compared at five kinds of Reynolds numbers. With the increase of obstacle height and the decrease of distance, the chaotic convection in the microchannel is enhanced. Especially at obstacle height (h) = 0.2 mm, obstacle distance (D) = 0.15 mm, and Re = 100, the vortex caused by the Minkowski fractal obstacle structure is more obvious. In addition, vortex phenomenon increases the contact area of two fluids and enhances chaotic convection. It shows that the flow direction of the fluid in the microchannel varies significantly.
The change of proinflammatory cytokine tumor necrosis factor α level in the use of meloxicam in rat model of osteoarthritis
Authors: Khotib Junaidi , Utami Naning Windi , Gani Maria Apriliani , Ardianto Chrismawan 
Published: December 2019

Abstract

Background
Osteoarthritis (OA) is a chronic disease in the joints. One of the proinflammatory cytokines that is thought to have a major role in the inflammatory process, the emergence of pain, and cartilage damage in OA is tumor necrosis factor α (TNF-α). Meloxicam is a nonsteroidal anti-inflammatory drug class of drugs that is relatively selective in inhibiting the activity of cyclooxygenase 2 (COX-2) formation. This study is conducted to prove the change in TNF-α level in the use of meloxicam with model in animals suffering from OA.

Methods
The OA rat model was induced with sodium monoiodoacetate intra-articularly. Rats were divided into 5 groups: negative control group, positive control group, and treatment groups with various doses of meloxicam. Hyperalgesia effect was evaluated using a warm plate test, and TNF-α level was determined using enzyme-linked immunosorbent assay.

Results
The treatment groups that received meloxicam at a dose of 1.0, 3.0, or 10.0 mg/kg body weight (BW) did not show significant differences in rat knee joint diameter (p = 0.99), but showed a significant difference in sensitivity to heat stimulation (p = 0.02) compared to the control group. Osteoarthritis rats experienced a significant reduction in TNF-α level after being given meloxicam at a dose of 10 mg/kg BW compared with the control group. This shows that the 10 mg/kg BW of meloxicam is a potential dose in reducing the TNF-α level in OA rat models.

Conclusions
Based on these data, it can be concluded that the inhibition of pain and the development of OA by meloxicam in animal models may be assigned to a decreased level of TNF-α.
Rent Control Sharing
Authors: Stern Stephanie M. 
Published: December 2019

Abstract
Rent-control laws limiting the rents private landlords can charge tenants are controversial in the United States. Critics have condemned rent control’s mandated wealth transfer from landlords to tenants, and economists have decried its negative effects on rental supply and quality. With the advent of the sharing economy, rent-controlled tenants can rent out their below-market units for short durations at market-level or premium prices, a practice I term “rent control sharing.” The reaction to rent-controlled tenants pocketing money from Airbnb and other homesharing sites at the expense of their hapless landlords has been negative. Yet, the sharing economy has not changed an essential feature of rent control: the redistribution of wealth from landlord to tenant. Instead, Airbnb and similar platforms have altered the form of the redistribution and the legal relations between landlord and tenant, and increased the salience of the wealth transfer from landlord to tenant. As a result, rent control sharing collides with public preferences for in-kind redistribution and stronger legal protections for property used personally or intimately. This Article explores how rent control sharing accentuates some of the flaws of rent control and fuels the debate over rent control’s future.

Assessment of the contribution of microbial activities to tomato growth and yield under an organic production system
Authors: Babalola Oluwatoyin A. 
Published: December 2019

AbstractOptimizing microbiological activities in an organic crop production system is crucial to the realization of optimum growth and yield of the crops. Field and pot experiments were conducted to assess soil microbial activities, growth and yield of tomato varieties in response to 4 rates of composted plant and animal residues. The trials were carried out in the Federal University of agriculture, Abeokuta Nigeria, between April 2014 and November 2015. The compost rates were 0, 5, 10 and 20 t ha−1, while the varieties used were Ibadan-improved and Ibadan-local. Fungi population, microbial biomass nitrogen and enzyme activities were significantly higher (P≤ 0.05) at the rhizosphere of the local variety than that of the improved variety. This led to a significantly higher number of branches, plant height, leaf area, number of fruits and less days to maturity in the local variety. Also, growth parameters and tissue N significantly increased in all compost treatments while dry matter yield and weight of fruits were significantly higher in soil amended with 20 t ha−1. Microbial activities correlated more significantly with growth and yield parameters at 6 weeks after transplanting. It was concluded that microbial activities could be optimized to improve the yield of tomato varieties in an organic production system, through the application of compost, particularly at 20 t ha−1.
Analysis of Lavapiés through its Linguistic Landscape and the Press
Authors: de Lobado García Ester Saiz , Guijarro Almudena Revilla 
Published: December 2019

Abstract
The XXth century gateway cities in Europe, such as Madrid, have followed and in-depth population readjustment, due to the arrival of immigrants from all over the world. This readjustment has left traces in the public spaces of the city; and the media have noted this phenomenon as well.
This paper aims at analysing the superdiversity present in Lavapiés, through two different and complementary methodologies: the analyses of the Linguistic Landscape and of press corpora. The analysis of the landscape of the territory will be conducted through a corpus of images or Linguistic Cartography that includes samples of multilingualism present in the area. The press corpora contain news stories, interviews and articles on immigration. These analyses will provide a better picture of the area, in terms of diversity. This paper is part of the Post-conference Special Issue on Language and Migration.
The Artists Village: Openly Intervening in the Public Spaces of the City of Singapore
Authors: Tan Adrian 
Published: December 2019

Abstract
This paper focuses on how the social, dialogical and collaborative strategies and practices of The Artists Village openly intervened in the public spaces of Singapore at various times in the city-state’s history from 1989 to 2015. The objective of this paper is to draw out how the artists collective used social situations to openly produce relational, participatory and socially engaged art in public spaces with specific functions, history and importance. These various forms of artistic interventions took place on a farm, in shopping malls, on public transport networks and at national monuments during different moments in Singapore’s rapid urban transformation. From these examples, one is able to understand why The Artists Village openly intervened in the public spaces of Singapore and how these interventions functioned in their limited scope. Through this study we are able to assess how the varying levels of collaboration, openness and criticality present in their public art projects enabled them to grow outside the centralised system of the nation-state in inserting their practice into the public sphere and engaging the masses.
A Causal-Pluralist Metatheory of Observation
Authors: Pessoa Osvaldo 
Published: December 2019

Abstract
An extended definition of “observation” is developed in order to account for the usage in the physical sciences and in neuropsychology. An observation is initially defined as a perception that has a focus of attention and is guided by theoretical considerations. Since the focus may change, one adopts a pluralist position according to which the object of perception may involve any stage of the causal chain that leads to perception, such as the source of light or sound, the obstructions, the medium or even the receptor. The “neutral” observations of the empiricists are seen as involving only low-level or medium-level theorization. Examples are examined, such as a lunar eclipse, the rainbow, and observations mediated by instruments, whose “artifacts” are considered observations of the instrument itself. One also defines null-effect observations. Observations of photographs and drawings may be considered either the observation of a printed sheet of paper or the observation of the pictured object or people. This causal-pluralist metatheory of observation also accepts that one may “observe light”, observe the retina, and observe parts of the brain which are outside the region of the “sensorium”. Illusions and hallucinations are analyzed within this “observational materialism”, which considers that qualia are self-observations of the brain. Criticisms that the approach is too wide in scope are analyzed in the conclusion.
Measuring human perceptions of expressivity in natural and artificial systems through the live performance piece Time to compile
Authors: Cuan Catie , Berl Erin , LaViers Amy 
Published: December 2019

Abstract
Live performance is a vehicle where theatrical devices are used to exemplify, probe, or question how humans think about objects, each other, and themselves. This paper presents work using this vehicle to explore human perceptions of robot and human capabilities. The paper documents four performances at three distinct venues where user studies were conducted in parallel to live performance. A set of best practices for successful collection of data in this manner over the course of these trials is developed. Then, results of the studies are presented, giving insight into human opinions of a variety of natural and artificial systems. In particular, participants are asked to rate the expressivity of 12 distinct systems, displayed on stage, as well as themselves. The results show trends ranking objects lowest, then robots, then humans, then self, highest. Moreover, objects involved in the show were generally rated higher after the performance. Qualitative responses give further insight into how viewers experienced watching human performers alongside elements of technology. This work lays a framework for measuring human perceptions of robotic systems – and factors that influence this perception – inside live performance and suggests black-that through the lens of expressivity systems of similar type are rated similarly by audience members.
Computational Methods for Production-Based Asset Pricing Models with Recursive Utility
Authors: Aldrich Eric Mark , Kung Howard 
Published: December 2019

Abstract
We compare local and global polynomial solution methods for DSGE models with Epstein- Zin-Weil utility. We show that model implications for macroeconomic quantities are relatively invariant to choice of solution method but that a global method can yield substantial improvements for asset prices and welfare costs. The divergence in solution quality is highly dependent on parameters which affect value function sensitivity to TFP volatility, as well as the magnitude of TFP volatility itself. This problem is pronounced for calibrations at the extreme of those accepted in the asset pricing literature and disappears for more traditional macroeconomic parameterizations.
Warten im Arrest
Authors: Eckold Anja 
Published: December 2019

Zusammenfassung
Dieser Beitrag beschäftigt sich mit den unterschiedlichen Erscheinungsformen, Situationen und gesellschaftlichen Kontexten des Wartens. Angesichts der Vielfältigkeit des Phänomens scheint der Versuch der Formulierung einer allgemeinen Theorie des Wartens kaum sinnvoll zu sein. Stattdessen fokussiert der Beitrag auf das explizite Warten als Sonderform im Sinne einer lebenspraktischen Grenzsituation. Diese Perspektive eröffnet dann ein Verständnis für die besondere Belastung, die mit dem Jugendarrest einhergeht, denn der Arrest ist in hohem Maße durch die Erzeugung expliziter Wartesituationen charakterisiert. Diese können als implizite Bestrafungsrituale angesehen werden. Der letzte Teil widmet sich der Frage der subjektiven Bewältigung des Arrests. An einem Fallbeispiel wird gezeigt, dass das durch den Arrest erzwungene explizite Warten als „unerträgliche Situation“ empfunden werden kann.
Updating a map of sufficient conditions for the real nonnegative inverse eigenvalue problem
Authors: Marijuán C. , Pisonero M. , Soto Ricardo L. 
Published: December 2019

Abstract
The real nonnegative inverse eigenvalue problem (RNIEP) asks for necessary and sufficient conditions in order that a list of real numbers be the spectrum of a nonnegative real matrix. A number of sufficient conditions for the existence of such a matrix are known. The authors gave in [11] a map of sufficient conditions establishing inclusion relations or independency relations between them. Since then new sufficient conditions for the RNIEP have appeared. In this paper we complete and update the map given in [11].
Achievable multiplicity partitions in the inverse eigenvalue problem of a graph

Published: December 2019

Abstract
Associated to a graph G is a set 𝒮(G) of all real-valued symmetric matrices whose off-diagonal entries are nonzero precisely when the corresponding vertices of the graph are adjacent, and the diagonal entries are free to be chosen. If G has n vertices, then the multiplicities of the eigenvalues of any matrix in 𝒮 (G) partition n; this is called a multiplicity partition.
We study graphs for which a multiplicity partition with only two integers is possible. The graphs G for which there is a matrix in 𝒮 (G) with partitions [n − 2, 2] have been characterized. We find families of graphs G for which there is a matrix in 𝒮 (G) with multiplicity partition [n − k, k] for k ≥ 2. We focus on generalizations of the complete multipartite graphs. We provide some methods to construct families of graphs with given multiplicity partitions starting from smaller such graphs. We also give constructions for graphs with matrix in 𝒮 (G) with multiplicity partition [n − k, k] to show the complexities of characterizing these graphs.
