The Interplay Between Obfuscation and Prominence in Price Comparison Platforms
Authors: Mamadehussene Samir 
Published: February 2020

This paper analyzes price comparison platforms’ equilibrium design of their search environments, namely the order under which firms are displayed (having a prominent firm or listing firms randomly) and how much price complexity firms are able to use. It is found that (1) the possibility to obfuscate amplifies firms’ willingness to pay for the prominent position; (2) when platforms sell prominence, they optimally allow for more obfuscation than they would if they were to display firms randomly; and (3) if platforms are sufficiently differentiated, they find it optimal to sell prominence. Thus, platforms exploit their market power over consumers by implementing a prominent position and allowing for large levels of obfuscation. This paper also finds that in equilibrium, there is tension between platforms and firms regarding how much price complexity is used: firms would like to use even more obfuscation than what the platform allows, so the platform must monitor firms’ prices to make sure that they are not excessively complex.

Authors: Yılmaz Medine , Sarı Hatice Yıldırım , Ünlü Meltem , Yetim Perihan 
Published: February 2020

Background: Cultural competence, an important part of patient-centred care, has been on the nursing agenda for many years. Aim: The aim of this study was to measure the intercultural effectiveness level of paediatric nurses, and to explore relationships between the level of intercultural effectiveness and some sociodemographic variables in paediatric nurses. Method: The study was conducted at İzmir Tepecik Training and Research Hospital's children's clinics in Turkey. A convenience sample of 98 paediatric registered nurses practising at the hospital was evaluated. To collect the study data, a sociodemographic characteristics questionnaire, a Cultural Approach in Nursing Care form and the Intercultural Effectiveness Scale (IES) were used. Results: The participating paediatric nurses' intercultural effectiveness levels were moderate, the problem they experienced most was the language problem and although many of them had not received adequate training in cultural care, based on their experiences, they regarded themselves as culturally competent. Conclusion: Cultural competence is vital in multi-ethnic and multicultural societies. Cultural competence training should be provided to nurses during nurse education, or in-service training during their professional life.
Reducing delays to administration of prothrombin complex concentrate in patients with vitamin K antagonist-related intracerebral haemorrhage
Authors: Marrinan Elizabeth , Chen Lucia , Werring David , Turner David 
Published: February 2020

Background/aims Four-factor prothrombin complex concentrate is the first-line treatment in vitamin K antagonist-related intracerebral haemorrhage. Early administration is associated with improved patient outcomes. A quality improvement project investigated delays in prothrombin complex concentrate administration in vitamin K antagonist-related intracerebral haemorrhage in order to reduce the time from computed tomography scan confirming intracerebral haemorrhage to prothrombin complex concentrate administration (scan-to-needle time). Method Twenty patients were identified by retrospective audit over a 3-year period. The median scan-to-needle time for prothrombin complex concentrate was 156 minutes. Several points of delay were identified, including contacting both haematology and transfusion departments for prothrombin complex concentrate dosing and dispensing. Following this audit, interventions were brought in which included the introduction of a protocol with a prothrombin complex concentrate dosing algorithm, negating the need to contact haematology before administration. A dedicated supply of prothrombin complex concentrate was given to the stroke unit avoiding the need to contact the transfusion service. Results A re-audit showed a 68% reduction in median scan-to-needle time from 156 minutes to 49 minutes. Prospective data collection is ongoing.

Polar-groups-modified polyimide based on a fiber Bragg grating for relative humidity sensors
Authors: Wu Heng , Sun Tengpeng , Peng Jiankun , Dai Jixiang , Yang Minghong 
Published: February 2020

In this work, the effect of the polar groups modified polyimide fiber Bragg grating relative humidity sensor was studied. Polyimide films containing different polar groups were deposited on fiber Bragg gratings by an impregnating method to form different relative humidity (RH) sensors. The experimental results show that the addition of a carboxyl group and a hydroxyl group in the synthesis could improve the humidity sensitivity (2.28 and 1.59 times, respectively) from 35% RH–95% RH. The sensor based on modified polyimide still has good linear response to humidity and temperature. In addition, the sensors containing a carboxyl group and a hydroxyl group can shorten the response time of the humidity sensor and improve the stability of the sensor at the same time.

Magnetic sensor based on serial-tilted-tapered optical fiber for weak-magnetic-field measurement
Authors: Lu Liang , Miao Yinping , Zhang Hongmin , Li Bin , Fei Chengwei , Zhang Kailiang 
Published: February 2020

An optical fiber magnetic field sensor based on serial-tilted-tapered fiber (STTF) integrated with magnetic fluid is proposed. The compact STTF structure consists of two closely tilted-tapered fibers with a length of approximately 836 µm, which results in stronger mode coupling. The transmission characteristics of the proposed sensor under different magnetic field intensities (MFIs) have been studied. The results show that the proposed structure has an outstanding response to MFI and that the highest sensitivity is 32.67 pm/Oe in wavelength and 0.0336 dB/Oe in transmission in the range of 0–75 Oe. The minimum resolution of the proposed sensor is up to 0.6734 Oe. These types of sensors have great potential application in weak magnetic field measurements due to their compact structure and good sensing performance.

We have studied polymer-free cladding power strippers for high-power fiber laser applications. A practical, rapid, and process-on-place chemical etching technique is presented to form surface roughness for efficient removal of the cladding light. The technique is methodically studied and performance contours are determined for frequently used 130, 250, and 400 µm double-clad fibers. The stripping efficiency and the thermal performance of the fabricated strippers are investigated with respect to such process parameters as etching time and etched fiber length.

Innovationsnetzwerke als Treiber für Wissenschaft-Praxis-Kooperationen: Ein Erfahrungsbericht
Authors: Kammler Friedemann , Schoormann Thorsten , Fuchs Alexander , Mauruschat Achim , Thomas Oliver , Knackstedt Ralf 
Published: February 2020

ZusammenfassungDie Kooperation von Wissenschaft und Praxis in anwendungsorientierten Förderprojekten ist zu einem wesentlichen Instrument der Forschung avanciert und intensiviert den Austausch von realen Problemstellungen und innovativen Lösungsansätzen. Themenschwerpunkte, die ein hohes Innovationspotenzial aufweisen, aber noch unscharf diskutiert sind, stellen jedoch klassische Kooperationsformen vor neue Herausforderungen: Einerseits wird die Konzeption eines Projekts vom geringen Kenntnisstand erschwert, andererseits sorgt die geringere Erfolgssicherheit für eine abnehmende Investitionsbereitschaft industrieller Partner. So kann die Forschung um „Künstlichen Intelligenzen“ als Beispiel genannt werden, deren hohe Komplexität im Feld der Kleinen und Mittelständischen Unternehmen eingangs Hemmungen verursachte. Um diesen Herausforderungen zu begegnen, berichtet der vorliegende Beitrag von Erfahrungen, die aus einer dreijährigen Kooperation von sechs Hochschulen und über 30 Praxispartnern in der Form eines Innovationsnetzwerkes gesammelt wurden. Dabei werden zunächst typische Akteure und deren Aufgabenfelder (z. B. Wissenschaftspartner als Lotsen für neue Ideen oder Unternehmen für die Evaluation und Anwendung neuer Forschungsresultate) sowie unterschiedliche Ergebnistypen (z. B. Pilotstudien, Spin-Offs und kooperative Lehrformate) des Innovationsnetzwerkes beschrieben. Zur Illustration der Ergebnisse werden zwei Anwendungsbeispiele von einer branchenübergreifenden Cross-Innovation aus der Lebensmittelindustrie sowie von einem aus dem Netzwerk heraus entstandenen Pilotprojekt zur Digitalisierung von Startup-Vorhaben aufgeführt. Abschließend werden darauf aufbauend Potenziale und Herausforderungen diskutiert, um Impulse für die Konzeption und Umsetzungen solcher Netzwerke abzuleiten.
Study on the Appropriate Production Parameters of a Gas-injection Blast Furnace
Authors: Song Liu , Xiaojie Liu , Qing Lyu , Xusheng Zhang , Yana Qie 
Published: February 2020

AbstractThe change regulations of the smelting parameters in a gas-injection blast furnace are investigated using theoretical calculations. The results show that when the volume of gas injected, the oxygen enrichment rate and the theoretical combustion temperature of tuyere are 600 m3/tHM, 10% and 1950~2200∘C, respectively, the conditions meet the smelting requirements of a blast furnace. With the increase of the oxygen enrichment rate, the required air volume decreases, the contents of CO and H2 in the top gas increase, and the content of CO2 first increases and then decreases.With an increase of the volume of gas injected, the coke rate decreases. In addition, when the oxygen enrichment rate and the volume of gas injected are 10% and 600 m3/tHM, respectively, the CO content of the top gas constantly increases with the increase of the coke rate, while the H2 and CO2 contents both decrease. With the increase of the H2 content in the gas, the direct reduction degree of iron gradually decreases and the volume shrinkage burden increases. Apparently, injecting gas into the blast furnace can prevent the theoretical combustion temperature from being too high and solve the contradiction between the upper cooling and lower heating of the blast furnace.
The German Connection
Authors: Epstein Louis 
Published: February 2020

In 1930 the French composer Darius Milhaud achieved a major career milestone: his ambitious opera Christophe Colomb received its premiere at Berlin’s Staatsoper Unter den Linden. The premiere was the most prestigious of a surprisingly large number of performances of Milhaud’s music in Germany in the late 1920s and early 1930s. Even as he found success in Germany, many French critics dismissed Milhaud’s music as frivolous or incomprehensible, and in 1930 the Paris Opéra had yet to stage one of Milhaud’s works. In the wake of the Berlin premiere, however, the specter of German cultural dominance provoked calls in Paris for reevaluation of Milhaud’s work. In response, the director of the Paris Opéra, Jacques Rouché, quickly secured the right to stage Milhaud’s next opera, Maximilien, and Milhaud subsequently received a string of state commissions. After years of struggle with French critics and institutions, Milhaud’s success abroad finally precipitated official recognition at home.
Milhaud owed his popularity in Germany and the subsequent transformation in his French reception to his relationship with the Viennese music publisher Universal Edition. Unpublished correspondence and contracts reveal how the firm orchestrated Milhaud’s success in Germany through a network of affiliated conductors, composers, and institutions. Universal Edition and its director, Emil Hertzka, played crucial but largely unrecognized roles in advancing Milhaud’s early career, and Milhaud’s letters demonstrate his keen appreciation for the advantages that working with Universal brought, both to his finances and to his international reputation. The transnational collaboration that enabled Milhaud’s German reception and facilitated his path to official recognition ultimately offers a thought-provoking counterexample to the historiography of chauvinism and antipathy that otherwise dominates narratives of interwar Franco-German musical relations.

Published: February 2020

BACKGROUND AND OBJECTIVES:
Children with established type 1 diabetes (T1D) who present to the emergency department (ED) with mild diabetic ketoacidosis (DKA) are often hospitalized, although outpatient management may be appropriate. Our aim was to reduce hospitalization rates for children with established T1D presenting to our ED with mild DKA who were considered low risk for progression of illness.

METHODS:
We conducted a quality improvement initiative between January 1, 2012, and December 31, 2018 among children and young adults ≤21 years of age with established T1D presenting to our tertiary care ED with low-risk DKA. Children transferred to our institution were excluded. DKA severity was classified as low, medium, or high risk on the basis of laboratory and clinical criteria. Our quality improvement initiative consisted of development and implementation of an evidence-based treatment guideline after review by a multidisciplinary team. Our primary outcome was hospitalization rate, and our balancing measure was 3-day ED revisits. Statistical process control methods were used to evaluate outcome changes.

RESULTS:
We identified 165 patients presenting with low-risk DKA. The baseline preimplementation hospitalization rate was 74% (95% confidence interval 64%–82%), and after implementation, this decreased to 55% (95% confidence interval 42%–67%) (−19%; P = .011). The postimplementation hospitalization rate revealed special cause variation. One patient in the postimplementation period returned to the ED within 3 days but did not have DKA and was not hospitalized.

CONCLUSIONS:
Hospitalization rates for children and young adults presenting to the ED with low-risk DKA can be safely reduced without an increase in ED revisits.
Дослідження процесів утилізації тепла пароповітряних сумішей: імітаційне моделювання
Authors: Ковальчук Д. А. , Мазур О. В. 
Published: February 2020

Розглянуті основні підходи до розробки імітаційних моделей, освітлені їх недоліки та переваги. Розглянута імітаційна модель процесу глибокої утилізації тепла пароповітряних сумішей з використанням парокомпресійного теплового насосу, до складу якої входять імітаційні моделі компресора, конденсатора, електронного розширювального вентиля, випарника, переохолоджувача та контактного теплообмінника – утилізатора тепла пароповітряних сумішей. Імітаційні моделі цих складових побудовані з використанням експериментальних даних, отриманих авторами в результаті виконання фізичних натурних експериментів на лабораторній дослідній установці. В імітаційній моделі випарника теплового насосу реалізовано функцію розрахунку «баластної» та «ефективної» витрати холодоагенту. «Баластна» витрата виникає за рахунок переохолодження холодоагенту до температури кипіння і супроводжується випаровуванням його частки, яка не приймає участі у відборі тепла випарником. Для цього до імітаційної моделі випарника була додана підсистема розрахунку перепаду температур кипіння (тиску) по довжині випарника в залежності від витрати холодоагенту та температурного напору у випарнику, що враховує довжину ділянки випарника на якій відбувається кипіння рідкої фази. Залежність перепаду тиску по довжині випарника від витрат холодоагенту через нього є не монотонно зростаючою функцією а має екстремум і спадає при рівнях перегріва холодоагенту від 15 до 0 °С. Тиск на виході випарника розраховується в моделі з використанням нелінійної функції двох змінних – положення електронного розширювального вентиля та частоти обертання компресора. Динамічні властивості каналів моделюються ланками, передатні функції яких були отримані в результаті фізичних експериментів. Проведена перевірка розробленої імітаційної моделі на адекватність, для чого було організовано ряд комп’ютерних експериментів з умовами, аналогічними умовам проведення натурних фізичних експериментів. Порівняння результатів моделювання та фізичного експерименту показало високу ступінь їх схожості.
