Modeling and design of cooperative braking in electric and hybrid vehicles using induction machine and hydraulic brake
Authors: Dalimus Zaini , Hussain Khallid , Day Andrew J.
Published: July 2016

In mixed-mode braking applications, the electric motor / generator (M/G) and hydraulic pressure valve are controlled to meet the driver’s braking demand. Controlling these braking elements is achieved by modulating the current generated by the M/G and adjusting the fluid pressure to the wheel brake cylinders. This paper aims to model and design combined regenerative and hydraulic braking systems which, comprise an induction electric machine, inverter, NiMH battery, controller, a pressure source, pressure control unit, and brake calipers. A 15 kW 1500 rpm induction machine equipped with a reduction gear having a gear ratio of 4 is used. A hydraulic brake capable to produce fluid pressure up to 40 bar is used. Direct torque control and pressure control are chosen as the control criteria in the M/G and the hydraulic solenoid valve. The braking demands for the system are derived from the Federal Testing Procedure (FTP) drive cycle. Two simulation models have been developed in Matlab®/Simulink® to analyze the performance of the control strategy in each braking system. The developed model is validated through experiment. It is concluded that the control system does introduce torque ripple and pressure oscillation in the braking system, but these effects do not affect vehicle braking performance due to the high frequency nature of pressure fluctuation and the damping effect of the vehicle inertia. Moreover, experiment results prove the effectiveness of the developed model.
A CFD model for analysis of performance, water and thermal distribution, and mechanical related failure in PEM fuel cells
Authors: Al-Baghdadi Maher A.R. Sadiq
Published: July 2016

This paper presents a comprehensive three–dimensional, multi–phase, non-isothermal model of a Proton Exchange Membrane (PEM) fuel cell that incorporates significant physical processes and key parameters affecting the fuel cell performance. The model construction involves equations derivation, boundary conditions setting, and solution algorithm flow chart. Equations in gas flow channels, gas diffusion layers (GDLs), catalyst layers (CLs), and membrane as well as equations governing cell potential and hygro-thermal stresses are described. The algorithm flow chart starts from input of the desired cell current density, initialization, iteration of the equations solution, and finalizations by calculating the cell potential. In order to analyze performance, water and thermal distribution, and mechanical related failure in the cell, the equations are solved using a computational fluid dynamic (CFD) code. Performance analysis includes a performance curve which plots the cell potential (Volt) against nominal current density (A/cm2) as well as losses. Velocity vectors of gas and liquid water, liquid water saturation, and water content profile are calculated. Thermal distribution is then calculated together with hygro-thermal stresses and deformation. The CFD model was executed under boundary conditions of 20°C room temperature, 35% relative humidity, and 1 MPA pressure on the lower surface. Parameters values of membrane electrode assembly (MEA) and other base conditions are selected. A cell with dimension of 1 mm x 1 mm x 50 mm is used as the object of analysis. The nominal current density of 1.4 A/cm2 is given as the input of the CFD calculation. The results show that the model represents well the performance curve obtained through experiment. Moreover, it can be concluded that the model can help in understanding complex process in the cell which is hard to be studied experimentally, and also provides computer aided tool for design and optimization of PEM fuel cells to realize higher power density and lower cost.

A Neural Network Approach to Soil Electrical Conductivity Estimation on Earthen Levees Using Spaceborne X-band SAR Imagery
Authors: Mahrooghy Majid , Aanstoos James , Nobrega Rodrigo A. , Hasan Khaled , Younan Nicolas H.
Published: July 2016

Monitoring of soil moisture over earthen levees can help in revealing patterns of moisture variation which could indicate potential slope failures or other vulnerabilities. In this work a machine learning approach using a back propagation neural network (BPNN) and also a wavelet basis
neural network (WBNN) is developed to estimate the soil electrical conductivity (EC) over an earthen levee system. Three scenarios based on the extracted features are investigated to estimate the conductivity. In scenario one, only radar backscatter coefficients are considered. In scenario
2, in addition to the backscatter features an average of backscatter in a sliding 3 × 3 window is used. In scenario 3, texture features are added, including statistical and wavelet features. The results show that using all backscatter and texture features (scenario 3) results in better
correlation performance, with an 11 to 27 percent improvement compared to scenario 1 and a 1 to 17 percent improvement over scenario 2.
Geometrical Consistency Voting Strategy for Outlier Detection in Image Matching
Authors: Lu Luping , Zhang Yong , Tao Pengjie
Published: July 2016

False matches in tie-point image matching are common. This paper introduces a straightforward and effective prepossessing method to reject false matches from initial matches. The method is based on the idea of Hough transform using only two geometrical consistency parameters, namely,
the scale parameter and the rotation parameter between two images. A weighted voting strategy is employed, and it can further improve the robustness of the algorithm. The method can handle a large rate of outliers and produce more robust matches with low complexity. No assumptions with regard
to the relative pose between two images are necessary, and large perspective deformation can be handled as well. Experiments with ground reference data show that the algorithm works effectively even when the ratio of inliers is below 10 percent. In these data, the ratio of inliers can be improved
from 5 percent to 40 percent on average.
Besetzungen - Japanische Entwicklungsräume in Palästina
Authors: Ganseforth Sonja
Published: July 2016

Wie kaum ein anderes Land hat Palästina weltweit die Vorstellung eines »besetzten Landes« geprägt. Seit den 1990er Jahren steht das Land zudem im Fokus der internationalen Entwicklungspolitik - mit zum Teil absurden Effekten. Sonja Ganseforth zeigt die Verwerfungen und Widersprüchlichkeiten entwicklungspolitischer Interventionen anhand einer für den Westen scheinbar außergewöhnlichen Perspektive - die der japanischen Entwicklungspolitik. Sie stellt sie in ihren historischen Kontext und deckt die unterliegenden Dynamiken von Raumbesetzungen jenseits des Militärischen auf, von denen Entwicklungspolitik nicht nur in Palästina geprägt ist.
Kulturelle Geographien der Vielfalt
Authors: Scherle Nicolai
Published: July 2016

Wie tolerant ist unsere Gesellschaft angesichts einer kaum noch zu überblickenden Vielfalt an Identitäten und Lebensstilen? Begreifen wir sozio-kulturelle Heterogenität als Chance oder empfinden wir sie als Belastung? Inwieweit können Unternehmen die Potentiale eines strategischen Diversitätsmanagements in Wert setzen? Nicolai Scherle nähert sich diesen Fragen, die in den letzten Jahren verstärkt in den öffentlichen Diskurs gerückt sind. Sein Plädoyer für »gelebte Vielfalt« jenseits von Political Correctness und strategischen Markt- oder Personalüberlegungen setzt sich umfassend mit menschlicher Heterogenität auseinander - aus unterschiedlichen konzeptionellen Perspektiven, in verschiedenen historischen Kontexten und aus einem Blickwinkel, der Theorie und Praxis verbindet.
Epistemologie der Stadt
Authors: Dell Christopher
Published: July 2016

Die verstädterte Welt zeigt sich heute als sozio-materiales Produkt eines mit Unbestimmtheit durchsetzten, raumproduzierenden Handelns. Auffassungen, die noch von einer vorgegebenen und nur noch abzubildenden Stadt ausgehen, greifen längst nicht mehr. In diesem Verlust liegt jedoch die Chance danach zu fragen, wie das neu entstandene epistemologische Feld des Urbanen zum Verhandlungsgegenstand werden kann. Im Dialog mit wissens- und darstellungstheoretischen Fragestellungen zeigt Christopher Dell, wie das Wissen des Städtischen heute aufzuschließen ist: medial orientiert am Modus einer gestalterischen Diagrammatik und performativ gebunden an eine improvisatorische Praxis. Dabei entsteht ein Anforderungskatalog an die Artikulation von Wissensformen, die nicht feststellen, sondern ermöglichen. Das Buch ist kritische Analyse und grundlegendes Werk zugleich - es liefert die erste umfassende Rahmung für ein wissenstheoretisch basiertes Verständnis aktueller Stadtforschung.
Genealogie der Ethikpolitik
Authors: Könninger Sabine
Published: July 2016

Nationale Ethikkomitees gelten als adäquate Lösung für ethische Probleme lebenswissenschaftlicher - und zunehmend auch nanotechnologischer - Entwicklungen. Aber wann, wie und in welchem Kontext setzten sich diese Ethikpolitiken durch? Und wogegen? Diesen Fragen geht Sabine Könninger am Beispiel Frankreichs nach und zeigt, wie sich eine Regierungstechnologie etablierte, in der Kritik an Forschungszielen und -zwecken unerwünscht ist. Die Studie bietet einen kritischen Forschungsbeitrag zu ethischen Institutionen und Diskursen im Bereich der Science and Technology Studies. Umfangreich erschließt sie einem deutschsprachigen Publikum die Auseinandersetzungen um Wissenschaft und Technik in Frankreich.
Strategien der Individualisierung
Authors: Krings Bettina-Johanna
Published: July 2016

Der Begriff der Individualisierung trägt in der Regel negative Konnotationen: sei es im Hinblick auf eine zunehmende Vereinzelung und Vereinsamung von Individuen oder hinsichtlich der Zunahme egoistisch anmutender Handlungen von Menschen, die das Gemeinwohl aus dem Blick verlieren. Prozesse der Individualisierung werden daher häufig als Bedrohung für die Konstituierung moderner Gesellschaften diskutiert. Diese Studie hingegen präsentiert eine neue Lesart der Individualisierung. Orientiert an Niklas Luhmanns Arbeiten und gestützt auf Ergebnisse einer empirischen Studie legt Bettina-Johanna Krings eine soziologische Betrachtung vor, die die Aufforderung zur Individualisierung als eine notwendige Herausforderung in modernen Gesellschaften interpretiert.
Hybride Alltagswelten
Authors: Yildiz Miriam
Published: July 2016

Migrationsbedingte Vielfalt und durch Mobilität geprägte hybride Lebenswelten sind Teil der gesellschaftlichen Normalität. Dennoch werden Jugendliche zweiter und dritter Generation oft im Zusammenhang mit Sicherheitsproblemen, Integrationsfragen und sogenannten ›sozialen Brennpunkten‹ thematisiert. Wichtige Handlungs- und Deutungsressourcen - sowohl für die Soziale Arbeit als auch für die kulturelle und pädagogische Praxis - bleiben aus diesem einseitigen Blickwinkel jedoch unerschlossen. Miriam Yildiz kehrt die Perspektive um: Sie rückt Ressourcen, Lebenspraxen und Diskriminierungserfahrungen von Jugendlichen systematisch in den Mittelpunkt und bietet damit erkenntnisreiche Einblicke jenseits von Stereotypisierungen.
Ereigniszeit und Eigenzeit
Authors: Genç Metin
Published: July 2016

Zeit wird in der Moderne zunehmend als sich wandelndes Gewebe aus gegeneinander und miteinander laufenden Eigenzeiten erfahren, die sich je neu behaupten müssen. Nach Niklas Luhmann bringt diese Behauptungsdynamik paradoxerweise selbst wiederum erst die Zeit hervor, um die diskursiv und kulturell Bestimmungskämpfe stattfinden. Metin Genç führt diese systemtheoretische Einsicht mit literarischen Zeithandhabungen zusammen und entwickelt daraus ein innovatives Analysemodell für ästhetische und textuelle Formen temporaler Komplexität. Erprobt wird dieses Modell an literarischen Experimenten von Alexander Kluge und Thomas Lehr, die die Ereignishaftigkeit und Zeitlichkeit der Zeit (re)konstruieren, lesbar machen, entfalten und dynamisieren.
Widerspenstige Alltagspraxen
Authors: Sauer Madeleine
Published: July 2016

Widerspenstige Alltagspraxen sind kollektive Experimente, die sich auf der Suche nach emanzipatorischen Alternativen menschlichen Zusammenlebens und -arbeitens befinden. In drei Suchbewegungen verfolgt Madeleine Sauer die Frage, wie dominante Wissensproduktionen über Kapitalismus und Demokratie die Analyse widerspenstiger Alltagspraxen erschweren, welche queer-feministischen und herrschaftskritischen Theorieperspektiven dazu beitragen, jene Praxen in den Fokus zu nehmen, und was die Theorieproduktion von den gelebten Praxen lernen kann. Hierzu werden drei Praxisbeispiele aus dem Bereich der Raum(aneignungs)- und Stadtpolitiken - das Mietshäuser Syndikat, der Wagenplatz Schwarzer Kanal und das Projekt NewYorck im Bethanien - exemplarisch analysiert.

Bewegung und Gesundheit in der Kita
Authors: Erhorn Jan , Schwier Jürgen , Hampel Petra
Published: July 2016

Gesunde Kinder sind aktive Kinder! Ein wahrer Satz. Deswegen sind Bewegung und Gesundheit zentrale Themen - bereits im frühen Kindesalter. Die Bedeutung frühkindlicher Bildung gewinnt an gesellschaftlicher Wertschätzung, Kindertageseinrichtungen werden ausgebaut. Um diese Entwicklung optimal zu nutzen, bedarf es einer qualitativen Weiterentwicklung der Bildungsangebote. Hier setzen die Beiträge des Bandes an und führen praxisnah in Konzepte und Handlungsfelder der frühkindlichen Bewegungsförderung ein. Sie liefern Hinweise und Anregungen für eine spielerische, aber wissenschaftlich fundierte Bewegungsförderung im Kita-Alltag und beleuchten Möglichkeiten, die sich aus den Zusammenhängen zwischen Sprachförderung und Bewegung ergeben. Dabei zeigen sie nicht nur, wie die Gesundheit der Kinder gefördert werden kann. Gerade in Zeiten des Fachkräftemangels an Kitas sind diese Analysen und Konzepte auch für die Gesundheit der Betreuer_innen von unschätzbarem Wert.
Frankophone digitale Literatur
Authors: Bauer Elisabeth Carolin
Published: July 2016

Hyperfiction, digitale Poesie & Co. - seit Beginn der digitalen Revolution haben frankophone Autor_innen mit dem literarischen Potential der digitalen Medien experimentiert. Insbesondere im eigenen Land blieben den Werken aber bislang Publikumserfolg und literaturwissenschaftliche Anerkennung verwehrt. Elisabeth Carolin Bauer setzt eine Auswahl der Werke in einen historischen Kontext und wirft einen literaturwissenschaftlich-analytischen Blick unter die postmodern leichte Oberfläche. Sie zeigt: Die klassischen narrativen Verfahren sind im neuen Medium weiter gültig, doch ihre Ausformulierung in eigenen genuinen Techniken ist stets überraschend und virtuos. »Digitale Literatur« hat den Rang einer eigenen Mediengattung neben z.B. »Hörspiel« und »Film« durchaus verdient.
Genre und Gender
Authors: Breuer Johannes
Published: July 2016

Die Beziehung von Genre und Gender ist Kristallisationspunkt verschiedenster Einschätzungen und Effekte. Doch wie gestaltet sich das Wissen um beide Kategorien in ihrer Verknüpfung? Und wie ist es in seiner konstitutiven Wechselseitigkeit zu erfassen? Ausgehend von dieser Fragestellung entwirft Johannes Breuer eine methodisch präzise Diskursivierung, die am Beispiel des Musicals zeigt, wie Genre und Gender einander bedingen und darin zugleich Spannungsmomente evozieren. In seiner detailreichen Aufarbeitung tritt die Komplexität beider Kategorien hervor, indem über disziplinäre Grenzen hinweg verschiedene Entwürfe der Gender Studies und der Medienwissenschaft zusammengebracht werden.
Die Politik der Echokammer
Authors: Lütjen Torben
Published: July 2016

In den USA stehen sich heute zwei politische Lager - Demokraten und Republikaner, Liberale und Konservative - in existenzieller Feindschaft gegenüber. Doch was erklärt den tiefen ideologischen Graben, der das Land durchzieht? In seinem Buch zeigt Torben Lütjen, wie die USA in ein Land politischer Echokammern zerfielen: virtuelle und soziale Räume, die vor allem von Gleichgesinnten bevölkert werden und sich durch das Fehlen von Widerspruch ideologisch radikalisiert haben. Der Blick geht dabei vor allem nach Wisconsin, in den Mittleren Westen der USA: Hier verkörpert sich in zwei extremen Parteihochburgen von Demokraten und Republikanern paradigmatisch der Konflikt, der die modernen USA prägt.
Elektronik als Schöpfungswerkzeug

Published: July 2016

Der deutsch-amerikanische Künstler Stephan von Huene (1932-2000) gehört zu den Medienkünstlern der ersten Generation, die sich der Elektronik als Schöpfungswerkzeug bedienten. Sein Œuvre entfaltet sich im Spannungsfeld zwischen Figuration, Akustik, Kinesik und Kommunikationstheorie. Jesús Muñoz Morcillo liefert die erste Monografie, die sich dem Werk von Huenes systematisch widmet und dieses - mit Blick u.a. auf John Cage und La Monte Young - kunsthistorisch einordnet. Die hermeneutische Analyse der letzten großen Arbeit von Huenes (Sirenen Low, 1999) liefert die Grundlage für drei umfangreiche Deutungskreise, die sich jeweils den figurativen, akustischen und systemischen Aspekten seines Werkes zuwenden.
Transnational Black Dialogues
Authors: Nehl Markus
Published: July 2016

Markus Nehl focuses on black authors who, from a 21st-century perspective, revisit slavery in the U.S., Ghana, South Africa, Canada and Jamaica. Nehl's provocative readings of Toni Morrison's A Mercy, Saidiya Hartman's Lose Your Mother, Yvette Christiansë's Unconfessed, Lawrence Hill's The Book of Negroes and Marlon James' The Book of Night Women delineate how these texts engage in a fruitful dialogue with African diaspora theory about the complex relation between the local and transnational and the enduring effects of slavery. Reflecting on the ethics of narration, this study is particularly attentive to the risks of representing anti-black violence and to the intricacies involved in (re-)appropriating slavery's archive.
Atmospheric Pressure Plasma Treatment of Nylon 6,6 and Polyester Fabrics for Enhancing Antistatic Properties
Authors: Dincmen Melek Gul , Hauser Peter J. , Gursoy Nevin Cigdem
Published: July 2016

In this study, antistatic properties of nylon 6,6 and polyester fabrics were improved. Diallyldimethylammonium chloride (DADMAC) monomer was used as an antistatic agent together with di(ethylene glycol) diacrylate crosslinker. Non-thermal, high density atmospheric pressure plasma was used to graft and polymerize the monomer/crosslinker layer on the fabric. Surface resistivity and electrostatic charge generation/dissipation of fabrics were measured after Soxhlet extraction with water and after home laundering. All fabrics were stained with C.I. Direct Red 80 to confirm the newly grafted polyDADMAC layer on the fabric and UV-Visible spectroscopic analyses were carried out on dye baths. Results showed that the grafted polyDADMAC layer was still present after water Soxhlet extraction and after home laundering. The antistatic performance of the fabrics was greatly improved with the treatment.
Why do males prefer nursing?
Erkekler hemşireliği neden tercih ediyor?
Authors: Güven Şefika Dilek , Küçükakça Gülden , Çalbayram Nazan
Published: July 2016

This descriptive study was conducted to determine the reasons why male students would choose the nursing profession. The study sample consisted of 71 students who agreed to participate in the study. It was found that 78.9% of the students marked nursing as their 1st to 5th choice and 66.2% of them were happy to study in the nursing department. The top reason for selecting the profession was that their families and community wished them to do so. Family and community encouragement and better employment opportunities were the first two factors that influenced male students in choosing their profession and they stated that they were pleased to study nursing. Although their being content with nursing education was positive in the sense that it showed that male students have internalized bearing the title of a nurse, the fact that they acted upon the wishes of their family and community rather than deciding on their career on their own may lead to problems in the future including being dissatisfied with the profession. ÖzetAraştırma erkek öğrencilerin hemşirelik mesleğini seçme nedenlerini belirlemek amacıyla tanımlayıcı tipte yapılmıştır. Araştırmaya katılmayı kabul eden 71 öğrenci araştıranın örneklemini oluşturmuştur. Öğrencilerin; %78.9’unun hemşireliği 1.-5. sırada tercih ettikleri ve %66.2’sinin hemşirelik bölümünde okumaktan memnun olduğu belirlenmiştir. Öğrencilerin mesleği seçmelerinin ilk nedeni ailem ve çevrem istediği için olarak belirlenmiştir. Erkek öğrencilerin meslek seçimlerinde aile ve çevre isteği ve iş olanağının yüksek olması nedenlerinin ilk iki sırada yer aldığı ve hemşirelik okumaktan memnun oldukları belirtmişlerdir. Hemşirelik okumaktan memnun olmaları erkek öğrencilerin hemşire unvanını benimsediklerini göstermesi açısından olumlu olmasına karşın meslek seçimlerinde aile ve çevre isteği kişinin meslek seçimine kendisinin karar vermemesi nedeniyle gelecekte meslekte doyum sağlayamama gibi bir soruna neden olabileceğini düşündürmektedir.

Review of the diagnosis and pharmacological management of pulmonary arterial hypertension in connective tissue disease
Authors: Tang Chun-Pong , Lee Ka-Lai , Ying King-Yee
Published: July 2016

Connective-tissue-disease-associated pulmonary arterial hypertension (CTD-PAH) is a well-recognised pulmonary complication most commonly seen in patients with systemic sclerosis, followed by systemic lupus erythematosus and mixed connective tissue disease. In systemic-sclerosis-associated-pulmonary arterial hypertension (SSc-PAH), patients usually present late and the progression can be rapid with poor prognosis and survival. Early detection and prompt intervention of SSc-PAH is an important cornerstone to halt the disease progression. Various pulmonary vasodilatory agents were developed over the past two decades. They were shown to improve patients’ symptoms, functional status, exercise capacity, haemodynamics and long-term survival. Other immunosuppressive therapies also demonstrated to improve symptoms and functional status in certain group of patients. This article is to review the diagnosis and pharmacological management of patient with CTD-PAH.
Big by blocks: modular analytics
Authors: Hahmann Martin , Hartmann Claudio , Kegel Lars , Habich Dirk , Lehner Wolfgang
Published: July 2016

Big Data and Big Data analytics have attracted major interest in research and industry and continue to do so. The high
demand for capable and scalable analytics in combination with the ever increasing number and volume of application
scenarios and data has lead to a large and intransparent landscape full of versions, variants and individual
algorithms. As this zoo of methods lacks a systematic way of description, understanding is almost impossible which
severely hinders effective application and efficient development of analytic algorithms. To solve this issue we propose
our concept of modular analytics that abstracts the essentials of an analytic domain and turns them into a set of
universal building blocks. As arbitrary algorithms can be created from the same set of blocks, understanding is eased and
development benefits from reusability.
A Riesz representation theory for completely regular Hausdorff spaces and its applications
Authors: Nowak Marian
Published: July 2016

Let X be a completely regular Hausdorff space, E and F be Banach spaces. Let Cb
(X, E) be the space of all E-valued bounded, continuous functions on X, equipped with the strict topology β. We develop the Riemman-Stieltjes-type Integral representation theory of (β, || · ||
F
) -continuous operators T : Cb
(X, E) → F with respect to the representing Borel operator measures. For X being a k-space, we characterize strongly bounded (β, || · ||
F
)-continuous operators T : Cb
(X, E) → F. As an application, we study (β, || · ||
F
)-continuous weakly compact and unconditionally converging operators T : Cb
(X, E) → F. In particular, we establish the relationship between these operators and the corresponding Borel operator measures given by the Riesz representation theorem. We obtain that if X is a k-spaceand E is reflexive, then (Cb
(X, E), β) has the V property of Pełczynski.
Flap motion of helicopter rotors with novel, dynamic stall model
Authors: Han Wei , Liu Jie , Liu Chun , Chen Lei , Su Xichao , Zhao Peng
Published: July 2016

In this paper, a nonlinear flapping equation for large inflow angles and flap angles is established by analyzing the aerodynamics of helicopter blade elements. In order to obtain a generalized flap equation, the Snel stall model was first applied to determine the lift coefficient of the helicopter rotor. A simulation experiment for specific airfoils was then conducted to verify the effectiveness of the Snel stall model as it applies to helicopters. Results show that the model requires no extraneous parameters compared to the traditional stall model and is highly accurate and practically applicable. Based on the model, the relationship between the flapping angle and the angle of attack was analyzed, as well as the advance ratio under the dynamic stall state.

Authors: Si Xinhui , Yuan Lili , Cao Limei , Zheng Liancun , Shen Yanan , Li Lin
Published: July 2016

We investigate an unsteady incompressible laminar micropolar flow in a semi-infinite porous pipe with large injection or suction through a deforming pipe wall. Using suitable similarity transformations, the governing partial differential are transformed into a coupled nonlinear singular boundary value problem. For large injection, the asymptotic solutions are constructed using the Lighthill method, which eliminates singularity of solution in the high order derivative. For large suction, a series expansion matching method is used. Analytical solutions are validated against the numerical solutions obtained by Bvp4c.

Sensitivity and specificity of the method used for ascertainment of healthcare-associated infections in the second Slovenian national prevalence survey
Authors: Serdt Mojca , Lejko Zupanc Tatjana , Korošec Aleš , Klavs Irena
Published: July 2016

Introduction

The second Slovenian national healthcare-associated infections (HAIs) prevalence survey (SNHPS) was conducted in acute-care hospitals in 2011. The objective was to assess the sensitivity and specificity of the method used for the ascertainment of six types of HAIs (bloodstream infections, catheter-associated infections, lower respiratory tract infections, pneumoniae, surgical site infections, and urinary tract infections) in the University Medical Centre Ljubljana (UMCL).

Methods

A cross-sectional study was conducted in patients surveyed in the SNHPS in the UMCL using a retrospective medical chart review (RMCR) and European HAIs surveillance definitions. Sensitivity and specificity of the method used in the SNHPS using RMCR as a reference was computed for ascertainment of patients with any of the six selected types of HAIs and for individual types of HAIs. Agreement between the SNHPS and RMCR results was analyzed using Cohen’s kappa coefficient.

Results

1474 of 1742 (84.6%) patients surveyed in the SNHPS were included in RMCR. The sensitivity of the SNHPS method for detecting any of six HAIs was 90% (95% confidence interval (CI): 81%-95%) and specificity 99% (95% CI: 98%-99%). The sensitivity by type of HAI ranged from 63% (lower respiratory tract infections) to 92% (bloodstream infections). Specificity was at least 99% for all types of HAIs. Agreement between the two data collection approaches for HAIs overall was very good (κ=0.83).

Conclusions

The overall sensitivity of SNHPS collection method for ascertaining HAIs overall was high and the specificity was very high. This suggests that the estimated prevalence of HAIs in the SNHPS was credible.

Published: July 2016

Objectives

Nasal obstruction is highly subjective perception with numerous efforts being made towards objective measuring. Many instruments in quality of life studies encompass subjective symptom of nasal obstruction, but only NOSE has been properly validated and is easy to use in every day practice.

Methods

Multicenter prospective instrument validation and cross-cultural adaptation cohort study was conducted on patients with deviated nasal septum, with or without inferior turbinate hypertrophy, to develop the Slovenian version of NOSE questionnaire. A cross-cultural adaptation of the original questionnaire was done in five steps, producing Slovenian NOSE-si, used on a pilot group to confirm the quality of adapted tools and, afterwards, on the main study and control group. Symptoms were lasting for more than 12 months and all had an indication for septal surgery. A control group was selected from a pool of healthy subjects, self-assessed as having no rhinological complaints.

Results

NOSE-si was used on 116 patients (58 from the study group vs. 58 from the control group). High degree of internal consistency - Cronbach’s a 0.971 and reliability after retesting - Goodman-Kruskal gamma coefficient 0.984 was proven. Responsiveness was confirmed in the surgery subgroup with standardized response mean (SRM) 2.76 (p<0.001).

Conclusions

The study produced a valid Slovenian version of NOSE questionnaire through rigorous and well defined five-phase effort to maintain scientifically comparable QoL instrument, and may be used by clinicians and researchers.
The adaptation and implementation of guidelines for responsible media reporting on suicide in Slovenia
Authors: Roškar Saška , Tančič Grum Alenka , Poštuvan Vita , Podlesek Anja , De Leo Diego
Published: July 2016

Introduction

The existing literature provides evidence of the link between media reporting and suicide in terms of either preventive or provocative effects. Hence, working with media representatives on responsible reporting on suicide is of great importance. Until recently in Slovenia, there has been an obvious lack of communication between media representatives and suicidologists. The aims of the present study were twofold; firstly, to introduce the adaptation and dissemination of intervention on responsible media reporting, and secondly, to evaluate the effectiveness of the implemented intervention on suicide reporting.

Methods

We used a pre-post research design. Newspaper articles were retrieved over two 12-month periods: the baseline period and the follow-up period. In between, we had a year of implementation of our intervention program (launching and disseminating the Guidelines via workshops). Each retrieved article was rated qualitatively with respect to its adherence to the Guidelines.

Results

The comparison of baseline and follow-up periods revealed some significant differences. Reporting in the follow-up period was less sensationalistic, there was less reporting about specific cases of suicides and more about causes of suicide and pathways out of mental distress. Furthermore, in the follow-up period, there was a significant improvement related to headlines of media articles. Contact information about where to seek help was more often included in the articles.

Conclusion

The findings are promising, but working with the media needs to be continuous and ongoing if sustainable results are to be achieved.
Zero-one completely positive matrices and
the A(R, S) classes
Authors: Dahl G. , Haufmann T. A.
Published: July 2016

A matrix of the form A = BBT where B is nonnegative is called completely positive (CP). Berman and
Xu (2005) investigated a subclass of CP-matrices, called f0, 1g-completely positive matrices. We introduce a
related concept and show connections between the two notions. An important relation to the so-called cut
cone is established. Some results are shown for f0, 1g-completely positive matrices with given graphs, and
for {0,1}-completely positive matrices constructed from the classes of (0, 1)-matrices with fixed row and
column sums.
Moore-Penrose inverse of a hollow symmetric
matrix and a predistance matrix
Authors: Kurata Hiroshi , Bapat Ravindra B.
Published: July 2016

By a hollow symmetric matrix we mean a symmetric matrix with zero diagonal elements. The notion
contains those of predistance matrix and Euclidean distance matrix as its special cases. By a centered
symmetric matrix we mean a symmetric matrix with zero row (and hence column) sums. There is a one-toone
correspondence between the classes of hollow symmetric matrices and centered symmetric matrices, and
thus with any hollow symmetric matrix D we may associate a centered symmetric matrix B, and vice versa.
This correspondence extends a similar correspondence between Euclidean distance matrices and positive
semidefinite matrices with zero row and column sums.We show that if B has rank r, then the corresponding
D must have rank r, r + 1 or r + 2. We give a complete characterization of the three cases.We obtain formulas
for the Moore-Penrose inverse D+ in terms of B+, extending formulas obtained in Kurata and Bapat (Linear
Algebra and Its Applications, 2015). If D is the distance matrix of a weighted tree with the sum of the weights
being zero, then B+ turns out to be the Laplacian of the tree, and the formula for D+ extends a well-known
formula due to Graham and Lovász for the inverse of the distance matrix of a tree.
Vision & Change: Why It Matters
Authors: McLaughlin Jacqueline , Metz Anneke
Published: July 2016

The AAAS “Vision and Change” report (2011) has been inspiring undergraduate biology educators nationwide to rethink their educational approach, favoring active-learning strategies to better prepare today's students for a complex, data-rich future. Here, we consider the history of the movement, its place in the greater arena of STEM education, and the reasons why this new approach has never been more critical. We encourage all biology educators to consider becoming agents of change, and we focus on helpful resources and practical suggestions to help ABT readers take the plunge into (or at least get their feet wet in) the welcoming waters of Vision and Change.
Beyond Research with People
Authors: del Consuelo Chapela María
Published: July 2016

The purpose of this paper is twofold: to show my qualitative inquiry (QI) researcher position through the presentation of some aspects of what I do as a QI researcher, and, from this position, to engage in the discussion of what aims are required for ICQI and the mandate that is needed in the present hegemonic context. I argue that autonomic health words, meanings, and practices fade in the scientific neoliberal mist. In a situation where culture is the big weapon to resist hegemonic invasion, to lose autonomic meanings is worrying. To confront this situation, I conceived a critical idea of health promotion: emancipatory health promotion (EHP). A main EHP aim is, as didascalos, to put the research knowledge and tools in the hands of people. I present some key EHP concepts and explain that critical QI becomes for EHP a healing process of self-understanding and communication to engage in power struggles. In this context, I proceed to answer the questions concerned with ICQI aims and mandate.
About My Sugar-Free Life and Other Lies

This presentation explains my thoughts, reflections, and feelings about writing interpretive autoethnographic texts in a foreign language. This includes my discovery of myself as a northern Chilean woman who grew up and survived by resisting colonized daily realities. I resisted the oppression and the atrocities that occurred during the Pinochet regime from 1973 through 1990.

This is about Congress realities as qualities in change. A metaphysics perhaps or an art of Pirsig Zenlike (motor)cycle maintenance, knowing what quality is, and as one, but never. Attention as key for discovery learning and me. It is a making it through poem imagery.
Jazz, Power, and Soviet Youth in the Early Cold War, 1948−1953
Authors: Tsipursky Gleb
Published: July 2016

Examining the history of jazz in the Soviet Union between 1948 and 1953, this essay sheds light on the role of popular music in the cultural competition of the early Cold War. While the Soviet authorities pursued a tolerant policy toward jazz during World War II because of its wartime alliance with the United States, the outbreak of the Cold War in the late 1940s led to a decisive turn against this music. The Communist Party condemned jazz as the music of the “foreign bourgeoisie,” instead calling for patriotic Soviet music. Building on previous studies of the complex fate of western music in the USSR during the postwar decades, this article highlights a previously unexamined youth counterculture of jazz enthusiasts, exploring the impact of anti-jazz initiatives on grassroots cultural institutions, on the everyday cultural practices of young people, and on the Cold War’s cultural front in the USSR. It relies on sources from central and regional archives, official publications, and memoirs, alongside oral interviews with jazz musicians and cultural officials.
Unha lectura restaurativa da fase de investigación do proceso penal de menores: especial referencia á mediación penal
Authors: Alonso Salgado Cristina
Published: July 2016

A mediación penal converteuse, nos últimos tempos, en protagonista de gran parte dos debates doutrinais sobre a necesidade de modernizar o sistema de Xustiza penal español.Con todo, o certo é que a configuración do actual proceso presenta non poucas dificultades para a incorporación da mediación penal. E isto porque, entre outras cuestións, a súa estrutura mantén unha concepción decimonónica, polo debate principio de legalidade-oportunidade, etc.É por isto que resulta de especial interese o estudo da Lei Orgánica 5/2000, de 12 de xaneiro, Lei Orgánica de Responsabilidade Penal dos Menores, tendo en conta que, coa súa aposta por algúns postulados próximos á mediación, se rebaten algúns dos reparos habitualmente esgrimidos para censurar a posíbel incorporación xeneralizada da mediación no proceso penal de adultos.
Responsabilidad social empresarial en Cuba: Una visión desde el conocimiento jurídico en pos del desarrollo local
Authors: Soto Lien
Published: July 2016

Actualmente Cuba se encuentra inmersa en un proceso de importantes transformaciones económicas, donde el incremento del papel social de los estudios es reflejo de la necesaria vinculación entre ciencia-decisión política y sociedad. No existe hoy día un espacio donde las ciencias sociales y humanísticas, con su metodología y constructos cognitivos, no contribuya a la producción científica que tanto demanda el país. En este escenario pensar el Derecho con un enfoque CTS + I es esencial.Por otra parte, los Lineamientos de la Política Económica y Social del Partido y la Revolución aprobados en abril de 2011 declaran que la empresa estatal socialista es el eslabón fundamental de la economía, y en varios lineamientos se hace expresa alusión a la responsabilidad social de estas y al vínculo necesario entre empresa-territorio-sociedad; sin embargo, el marco regulatorio es difuso y  escasos han sido los trabajos realizados desde las ciencias jurídicas en relación a la Responsabilidad Social Empresarial, lo cual nos conduce a analizar la institución desde el contexto económico y social propio del país y su vínculo con el municipio como nicho de actores relevantes para el logro del desarrollo al cual se aspira. El presente trabajo está centrado en ofrecer una serie de ideas preliminares para identificar la Responsabilidad Social Empresarial de las empresas del sector púbico cubano e impulsar su desarrollo, sobre la base del examen del conocimiento jurídico como catalizador y palanca del desarrollo local en el país.
As estratégias de construção da imagem de Aécio Neves no PPG e no HGPE em 2014 e 2015
Authors: Oliveira Luiz Ademir de , Paravizo Mira Gustavo Fernandes
Published: July 2016

Este artículo analiza las estrategias de construcción de imagen del senador Aécio Neves (PSDB) em 2014 cuando corrío a la presidencia de Brasil. Se parte de la centralidad de los medios de comunicación como requisito previo para la política para entender cómo los actores políticos utilizan diferentes medios para construir, reforzar o cambiar la imagen pública. Tomando como técnica de investigación la análisis de contenido, el trabajo ofrece un análisis qualiquantitavivo de los discursos transmitidos por PSDB, cuya figura fuera Aécio en cuatro tiempos político-electorales: el Programa Gratuito de los Partidos (PPG) de 2014, el Tiempo Libre de Propaganda Electoral (HGPE) de Aécio en primera y segunda vueltas, y finalmente el PPG de 2015. De acuerdo con la investigación de SECOM (2015), la televisión sigue como soporte de comunicación más influyente, ya que el 95% de los entrevistados dicen ver la televisión y el 73% tenían este hábito diario.
Migración y política: modulaciones identitarias en un comedor comunitario de la ciudad de La Plata, Argentina
Authors: Rodrigo Federico
Published: July 2016

A partir del trabajo de campo etnográfico realizado en un comedor comunitario situado en la periferia de la ciudad de La Plata, Argentina, buscamos dar cuenta de las apropiaciones de las identificaciones nacionales y clasistas que realiza un grupo de mujeres bolivianas que participan en el mismo. Así, observamos que sus posicionamientos nacionales y de clase se constituyen entrelazados, migrando lógicas de diferentes campos de interlocución. Si bien encontramos una configuración del espacio público que relega la posibilidad de tramitar demandas ligadas a los derechos sociales desde posiciones particularistas, el trabajo también nos nuestra la existencia de ámbitos de socialización en los que estas adscripciones resultan fundamentales. De esta manera, observamos que las identificaciones se constituyen en una tensión compleja desarrollada en la circulación entre el espacio público político y los espacios cotidianos de socialización marcados por la bolivianidad.
Ciudad, cine y comunicación: escenarios de regeneración urbana
Authors: Lorente Bilbao José Ignacio
Published: July 2016

La ciudad es el objeto de una doble producción. Como objeto físico es el resultado de la intervención de disciplinas como el urbanismo, la arquitectura o la economía, las cuales generan en la ciudad constantes procesos de construcción, destrucción y transformación. Pero la ciudad es también un horizonte de sentido, el resultado de un imaginario que la ciudadanía proyecta sobre el espacio urbano construido. Y en la medida en que esta búsqueda y atribución de sentido se torna reflexiva, el sujeto urbano se construye a sí mismo como ciudadano en relación con los demás, con la diferencia y la alteridad. Este trabajo trata de dar cuenta del modo en que el cine ha pensado y expresado los procesos de intervención, las transformaciones y sentidos de la regeneración urbana en las ciudades contemporáneas.
Del extractivismo económico al extractivismo epistémico y ontológico
Authors: Grosfoguel Ramón
Published: July 2016

Desde un enfoque decolonial, este artículo recupera el concepto de extractivismo, através de una revisión crítica de las prácticas del capitalismo y del colonialismo, ambas inherentes, originarias de una misma raíz: el pensamiento occidentalo-céntrico. Las mutaciones del extractivismo económico en su expansión planetaria resultan evidentes en este texto, en las formas que describe de pillaje cognitivo (epistémico) y de constricción de la existencia (ontológico), además del desastre medioambiental que han ido provocando la aceleración de captación de recursos y materias primas, así como las imposiciones cada vez más violentas, armadas y genocidas, de ese capitalismo colonial, especialmente en el continente americano. El artículo, desde la voz de las víctimas, ofrece paradigmas y alternativas partiendo de la crítica de esas prácticas epistemicidas y de las resistencias indígenas al no-ser.
