What to expect from electronic patient record system implementation: lessons learned from published evidence
Authors: Priestman Ward , Sridharan Shankar , Vigne Helen , Collins Richard , Seamer Loretta , Sebire Neil J.
Published: June 2018

Background

Numerous studies have examined factors related to success, failure and implications of electronic patient record (EPR) system implementations, but usually limited to specific aspects.

Objective

To review the published peer-reviewed literature and present findings regarding factors important in relation to successful EPR implementations and likely impact on subsequent clinical activity.

Method

Literature review.

Results

Three hundred and twelve potential articles were identified on initial search, of which 117 were relevant and included in the review. Several factors were related to implementation success, such as good leadership and management, infrastructure support, staff training and focus on workflows and usability. In general, EPR implementation is associated with improvements in documentation and screening performance and reduced prescribing errors, whereas there are minimal available data in other areas such as effects on clinical patient outcomes. The peer-reviewed literature appears to under-represent a range of technical factors important for EPR implementations, such as data migration from existing systems and impact of organisational readiness.

Conclusion

The findings presented here represent the synthesis of data from peer-reviewed literature in the field and should be of value to provide the evidence-base for organisations considering how best to implement an EPR system.
Learning health systems need to bridge the ‘two cultures’ of clinical informatics and data science
Authors: Scott Philip J. , Dunscombe Rachel , Evans David , Mukherjee Mome , Wyatt Jeremy C.
Published: June 2018

Background

UK health research policy and plans for population health management are predicated upon transformative knowledge discovery from operational ‘Big Data’. Learning health systems require not only data, but feedback loops of knowledge into changed practice. This depends on knowledge management and application, which in turn depends upon effective system design and implementation. Biomedical informatics is the interdisciplinary field at the intersection of health science, social science and information science and technology that spans this entire scope.

Issues

In the UK, the separate worlds of health data science (bioinformatics, ‘Big Data’) and effective healthcare system design and implementation (clinical informatics, ‘Digital Health’) have operated as ‘two cultures’. Much National Health Service and social care data is of very poor quality. Substantial research funding is wasted on ‘data cleansing’ or by producing very weak evidence. There is not yet a sufficiently powerful professional community or evidence base of best practice to influence the practitioner community or the digital health industry.

Recommendation

The UK needs increased clinical informatics research and education capacity and capability at much greater scale and ambition to be able to meet policy expectations, address the fundamental gaps in the discipline’s evidence base and mitigate the absence of regulation. Independent evaluation of digital health interventions should be the norm, not the exception.

Conclusions

Policy makers and research funders need to acknowledge the existing gap between the ‘two cultures’ and recognise that the full social and economic benefits of digital health and data science can only be realised by accepting the interdisciplinary nature of biomedical informatics and supporting a significant expansion of clinical informatics capacity and capability.
Can we trust electronic health records? The smoking test for commission errors
Authors: Millares Martin Pablo
Published: June 2018

Background

Considerable interest exists on using general practice electronic health records (EHRs) for research and other uses. There is also concern on their quality.

Aim

We suggest a simple test to assess errors of commission and subsequently overall EHR data quality that can be done on a periodical basis.

Method

Patient records with simultaneous entries of three different stages on smoking were studied. The codes ‘never smoked tobacco’, ‘smoker’ and ‘ex-smoker’ should follow this chronological order. It should then be possible to extrapolate the overall level of errors of commission for the organisation.

Results

The smoking test in our sample found errors in 169 patients, with 60 cases where dual errors were discovered. We express it as an estimated error of commission level of 2.6% related to the total population of the practice.

Conclusions

Considering the constant and regular entries on smoking status (83.59% of the entries were done over last month), we can conclude smoking entries analysis can serve as a simple test to periodically assess the overall EHR data quality, and any trends.
Figurationsprozesse der Einwanderungsgesellschaft
Authors: Hüttermann Jörg
Published: June 2018

Seit den 1960er Jahren haben sich die Beziehungen zwischen Alteingesessenen und Zugewanderten in Deutschland grundlegend gewandelt - und mit ihnen die Gesellschaft. Mittels ethnographischer Analysen führt Jörg Hüttermann diesen Prozess der Figuration auf alltägliche Interaktionen zurück, die nur auf den ersten Blick unbedeutend erscheinen. Indem sie die in unterschiedlichen Kontexten wirkenden Interaktionsdynamiken freilegt und ein Verlaufsmuster des Figurationswandels herausarbeitet, ermöglicht es die stadtsoziologische Studie, den urbanen Alltag mit anderen Augen zu sehen.
Menschliches, Übermenschliches. Zur narrativen Struktur von Superheldencomics
Authors: Ditschke Stephan , Anhut Anjin
Published: June 2018

Der kulturwissenschaftliche Aufsatz verfolgt zwei Ansätze zur Bestimmung der Eigenschaften superheroischer Narrative: Zunächst wird eine funktionale Klassifikation des Superheldengenres anhand der »Grundorientierung« der Protagonisten vorgeschlagen. Diese ergibt sich primär aus dem telos der Superhelden - positiv auf die Bewahrung des Guten oder negativ auf die Beseitigung des Bösen bezogen - und aus ihrem natürlichen, affirmativen oder aversiven Verhältnis zu den eigenen Kräften und den damit verbundenen Fähigkeiten und Verpflichtungen. Anhand dessen wird u.a. eine Typologie erstellt, die Superhelden anhand ihrer sozialen Funktion einordnet. Darüber hinaus werden superheroische Narrative im Anschluss an Jurij M. Lotman als spezifische Konstellation unterschiedlicher semantischer Räume vorgestellt, die mit den gegensätzlichen Genre-Instanzen »Superheld«, »Superschurke« und der »etablierten Ordnung« besetzt sind. Zwischen ihnen bilden sich wiederkehrende Konfliktmuster, die im Laufe der Genreentwicklung Gegenstand systematisch rekonstruierbarer Veränderungen werden.
"Wir wittern Morgenluft, wir alten Gespenster". Friedlaender/Mynonas phantomatische Lektüre von Derridas Marxbuch
Authors: Thiel Detlef
Published: June 2018

Detlef Thiel inszeniert hier ein Gespräch zwischen Derrida, Shakespeare, Marx, Stirner und Friedlaender (1871-1946), der sich als Satiriker Mynona nannte. Er hat die Probleme von Indifferenz und Polarität so intensiv durchdacht wie niemand vor ihm (auch nicht die Romantiker in Schellings Fußspuren), und er hält einen Schlüssel bereit, um ein merkwürdiges Manöver Derridas aufzuschließen: jene »einzigartige Indifferenz« bei Kojève, welche die Zukunft für das Ereignis öffnet. Derridas Entwicklung des Phantomatischen, der hantologie wird skizziert. Sie bildet seit 1967 einen roten Faden, bis hin zur Telemedialität. Shakespeare bringt die Phantome ins Spiel. Marx und Derrida verwandeln sie in Narrative und sprechen nur über sie. Stirner und Friedlaender identifizieren sich geradezu leibhaftig mit ihnen. Alle wollen den Spuk beenden. Aber Derrida resigniert: Wir müssen mit den Gespenstern leben. Friedlaender jedoch würde eine anonym arbeitende différance als verantwortungslos zurückweisen. Er wittert Morgenluft: eine phantomfreie Geistesgegenwart, die es noch nicht gibt.
Derridas "Politik der Alterität".
Authors: Flatscher Matthias
Published: June 2018

Der Artikel geht erstens der Frage nach, in welcher Weise Derrida einerseits Anleihen von klassischen Utopien nimmt, um sich andererseits zugleich von ihnen zu distanzieren. In einem zweiten Schritt wird dargelegt, inwiefern er selbst Zukünftigkeit hinsichtlich ihres normativen Potentials für ethisch-politische Überlegungen fruchtbar zu machen versucht. Abschließend werden Derridas Ausführungen in demokratietheoretischer Hinsicht analysiert und ausgewertet.
Wiederholung als Widerstand?
Authors: Berndt Daniel
Published: June 2018

Akram Zaatari, Emily Jacir, Lamia Joreige, Walid Raad und Yasmine Eid-Sabbagh (re-)kontextualisieren historische Fotografien mittels verschiedener Medien und künstlerischer Formate. (Re-)Kontextualisieren ist dabei mit Wiederholen im Sinne eines nochmals Hervorbringens, eines Wi(e)derlesens gleichzusetzen. Daniel Berndt zeigt, welche unterschiedlichen Perspektiven die Künstler_innen im Zuge dieser Wiederholung auf die Fotografie entwickeln. In Hinblick auf ihre daran geknüpften Auseinandersetzungen mit der Geschichte Palästinas und dem Nahostkonflikt geht er zudem der Frage nach, inwiefern die Künstler_innen damit einen Beitrag zu geschichtsbildenden und identitätsstiftenden Prozessen leisten.
Unheimliche Schönheiten
Authors: Kalt Daniel
Published: June 2018

Der Ort, an dem sich das Land gegen das Meer öffnet, ist einer, an dem sich unheimliche Gestalten tummeln - und damit prädestinierter Schauplatz für die Kriminalliteratur! In der Postmoderne ist die Hafenstadt jedoch zu einem Liebling der Erlebnisgesellschaft geworden: Barcelona und Marseille sind mit ihrem Umbau zu Entertainment-Metropolen Paradebeispiele solch postindustrieller Hafenstädte. Und wie reagiert darauf die Kriminalliteratur? Daniel Kalts Analyse der Werke von Manuel Vázquez Montalbán, Eduardo Mendoza, Francisco González Ledesma, Andreu Martin sowie von Jean-Claude Izzo und Vertretern des »polar marseillais« zeigt, wie literarisches Verbrechen und behübschte Hafenviertel zueinander in einer neuen Beziehung stehen.
Schwuler* Fußball
Authors: Heissenberger Stefan
Published: June 2018

Durch Sprache diskriminiert und lange Zeit tabuisiert: schwule Fußballer. 2015 haben sie mit dem Coming-out des ehemaligen deutschen Nationalspielers Thomas Hitzlsperger eines ihrer ersten und prominentesten Gesichter erhalten. Jenseits von Scheinwerferlicht und Einzelfällen nimmt diese ethnografische Studie erstmalig den Alltag von schwulen* Fußballteams im Freizeit- und Amateurbereich in den Fokus. Die teilnehmende Beobachtung als Spieler-Trainer führte Stefan Heissenberger auf die Vorder- und Hinterbühnen dieses Unterfeldes des heteronormativen Fußballs. Die Ergebnisse zu Vereinspolitik, Geselligkeit, schwulen* Turnieren und Männlichkeiten sowie deren Einbettung in »den« Fußball setzen neue Impulse für die sozialwissenschaftliche und gesellschaftspolitische Auseinandersetzung mit der weltweit bedeutsamsten Sportart.
Räumliche Ressourcen
Authors: Ernst Rainer W.
Published: June 2018

Raum ist eine gesellschaftliche Ressource. Rainer W. Ernst zeigt: Die Qualität unserer Lebensräume wird einerseits durch unterschiedliche Eigenschaften bestimmt und andererseits durch demokratisierte Entscheidungsprozesse bilanziert und geprägt. Ihre Herkunft, Wirkung, Verfügbarkeit und Gestaltbarkeit zu begreifen und interessenspezifisch zu kombinieren und zu verorten, verlangt der Architektur das neue Arbeitsfeld der »Möglichkeitsräume« ab. Das Buch macht deutlich, wie Architekt_innen in diesem rückkoppelnden Verfahren zusätzliche Möglichkeiten für die kreative Gestaltung von Lebensräumen finden können.
Patti Smiths kosmopolitische Stimme
Authors: Kuckuk Henning E.
Published: June 2018

Über die facettenreiche Arbeit der 71-jährigen Künstlerin Patti Smith gibt es eine Flut von Informationen - nicht zuletzt durch das Internet. Auch ihre autobiografischen Werke Just Kids und M Train haben eine internationale Leserschaft gefunden. Henning E. Kuckuk setzt sich ausgehend von der interdisziplinären Amerikanistik und den Cultural Studies - mit Bezug auf politik- und sozialwissenschaftliche Parameter - erstmals wissenschaftlich mit ihrem Werk und Leben auseinander. Der Analyse liegen empirische Untersuchungen von Performances und der Website der Künstlerin zugrunde, die von einem breiten Publikum rezipiert werden. Wie Patti Smith spricht auch dieses Buch eine politisch aktive Öffentlichkeit an.
A regression error specification test (RESET) for the truncated regression model
Authors: Sapra Sunil
Published: June 2018

While a variety of specification tests are routinely employed to test for misspecification in linear regression model, such tests and their applications to the truncated and censored regression models are uncommon. This paper develops a regression error specification test (RESET) for the truncated regression model as an extension of the popular RESET for the linear regression model (Ramsey (1969)). The two proposed extensions TRESET1 and TRESET2 developed in the paper are applied to labor force participation data from Mroz (1987). The paper studies the empirical size and power properties of the proposed tests via Monte Carlo experiments. Our simulation results suggest that both TRESET tests have reasonably good size and power properties for the truncated regression model in medium to large samples. However, TRESET2 consistently outperforms TRESET1 both in terms of empirical size and power in our experiments.Â Â

Diagnóstico dos processos de homologação e certificação de produtos de natureza cibernética: perspectivas para a construção de um sistema nacional
Authors: Barbalho Sanderson César Macêdo , Monteiro Simone Borges Simão , Reis Ana Carla Bittencourt , Miranda Rhoxanna Crhistianth Farago
Published: June 2018

O uso de computadores, tablets, smartphones, relógios inteligentes, smartmeters, sistemas GPS e assim por diante, traz um benefício comum a todos aqueles que acessam tais tecnologias, porém, ao mesmo tempo, tais sistemas têm uma influência fundamental no aspecto da privacidade do indivíduo. Desta forma, torna-se premente em nossa sociedade ter um sistema que permita homologar e certificar produtos de natureza cibernética. O presente artigo tem como objetivo retratar um diagnóstico dos processos de homologação e certificação de produtos de natureza cibernética que são usados por órgãos da administração central e pelas forças armadas, com vistas a desenvolver um Sistema Nacional de homologação e certificação desse tipo de produto. A fim de desenvolver o diagnóstico foram realizadas pesquisas documentais em órgãos responsáveis pela certificação de produtos tecnológicos e foram realizados estudos de caso em cinco organizações públicas e privadas. Os resultados desses estudos foram sistematizados para serem validados em grupo focal com especialistas. Demonstrou-se uma visão compartilhada pelas empresas e órgãos quanto ao aspecto da certificação de produtos, mas não houve um entendimento consensual sobre a homologação. Foram identificados ainda processos realizados por órgãos governamentais que fogem ao escopo tradicional da homologação de produtos na literatura científica.
Desenvolvimento e análise de regras de sequenciamento da produção para minimização de medidas de atraso em flow shop com tempos de setup
Authors: Silva Tatiane Carvalho , Fuchigami Helio Yochihiro
Published: June 2018

As regras de sequenciamento são métodos de programação da produção que possuem como vantagens, dentre outras, sua fácil implementação e simples compreensão. Neste sentido, este trabalho tem como objetivo o desenvolvimento de novas regras de sequenciamento para a minimização de medidas de atraso em um ambiente flow shop com setup independente da sequência. Foram analisadas, como medidas de desempenho, o atraso total da programação, o atraso máximo e o número de tarefas atrasadas. O estudo considera um flow shop com m máquinas e n tarefas, e, portanto, traz resultados para diferentes ambientes (relacionados ao porte do problema). A pesquisa traz resultados também em relação aos diferentes cenários que se pode observar na produção, de acordo com um alto ou baixo fator de atraso e com a amplitude da faixa de datas de entrega. Os resultados foram gerados através da experimentação computacional. Dentre as novas regras de prioridade propostas, destacam-se os resultados obtidos pela regra SPT3, constituindo uma nova alternativa de sequenciamento da produção, capaz de apresentar melhor desempenho que a regra clássica EDD.
Análise de confiabilidade para formulação de estratégia de manutenção de equipamentos em uma empresa da indústria alimentícia
Authors: Komninakis Denis , Piratelli Cláudio Luis , Achcar Jorge Alberto
Published: June 2018

A função manutenção tem um importante papel na busca por vantagens competitivas pelas empresas. Nesse sentido, a análise de confiabilidade de equipamentos é parte fundamental para a definição e seleção de estratégias de manutenção mais adequadas. O objetivo deste trabalho é avaliar, por meio de análise de confiabilidade, a coerência da atual estratégia de manutenção de equipamentos de uma empresa da indústria alimentícia localizada no interior do Estado de São Paulo. O método de pesquisa utilizado foi a modelagem estatística aplicada ao tempo de reparo (TTR) e tempo entre falhas (TBF) de um conjunto de 6 máquinas de embalagem de uma das linhas de produção. Estes tempos foram modelados por distribuições de probabilidade Log-normal e Weibull. Os resultados apontam que a atual estratégia de manutenção preventiva adotada para os equipamentos não está adequada, pois os equipamentos se encontram na fase de mortalidade infantil do ciclo de sua vida útil, o que sugere o emprego da estratégia de manutenção corretiva com o objetivo de se identificar e eliminar as falhas de origem.

Zur Verbvalenz des sumerischen Ausdruckes nir ĝal2
Authors: Ceccarelli Manuel
Published: June 2018

The aim of this article is to study the verb valency of the Sumerian expression nir ĝal2. The attestations point to two different meanings that are related to different arguments. It is suggested that the basic meaning of nir ĝal2 is „to give off an aura of authority; show authority“. The comitative argument indicates thanks to whom, the ablative argument by means of what someone shows authority. The meaning „to trust“ would result from a valency expansion, which can be traced to at least the beginning of the second millennium and could have been influenced by the construction of the Akkadian verb takālu „to trust“. The object of trust is expressed by means of the terminative (things) and dative (persons) arguments. The locative is mostly used as a peripheral argument expressing the place or situation in which someone shows authority.
Sapaziti, Sapalulme und die Suppiluliumas von W/Pal(a)stin(a/i)
Authors: Simon Zsolt
Published: June 2018

This paper argues that the Neo-Assyrian spelling Sapalulme of a Neo-Hittite ruler does not represent a distortion of the name Suppiluliuma (as it is generally assumed), but a relatively close transcription of another Luwian name, the first member of which may be attested in the name of Sapa-ziti, Great King of Karkamiš. Since the name PURUS.FONS.MI of the statue of Suppiluliuma from Tall Taʿyīnāt cannot be read as Sapalulme, Suppiluliuma of the statue and Sapalulme cannot be identical rulers, contrary to the widespread view.
The Effects of Repeated Sprints on the Kinematics of 3-Point Shooting in Basketball
Authors: Slawinski Jean , Louis Julien , Poli Julien , Tiollier Eve , Khazoom Charles , Dinu Daniel
Published: June 2018

Fatigue modifies the kinematics of various sports-related movements. Basketball induces fatigue, however, the effects of fatigue on the kinematics of shooting have never been studied. This study analysed the effects of fatigue induced by repeated sprints on the kinematics of 3-point shooting (3PS) in young, elite basketball players (U18 level). 3D joint angles were calculated at the maximum and minimum heights of the centre of mass during 3PS, using inertial measurement units (Biomech system, Xsens Technologies BV, Enschede, The Netherlands). Height, velocity and the angle of the ball at the time of release were extrapolated from the wrist joint angles. All players performed four 3PS actions in dynamic conditions before and after a fatigue protocol at 70% of their maximal exercise capacity. The fatigue protocol consisted of a shuttle test with repeated 20-m sprints interspersed with sets of 5 jumps. There was no change in the kinematics of 3PS (p > 0.05), or the ball release variables (p > 0.05) following the fatigue protocol. This suggests that elite basketball players are able to cope with physical fatigue while performing coordinated movements such as 3PS.

Published: June 2018

The aim of this study was to examine the acute effects of soccer specific fatigue on muscular and neuromuscular function in male youth soccer players. Elite soccer players (n = 20; age 15.7 ± 0.5 y; body height 177.75 ± 6.61 cm; body mass 67.28 ± 8.29 kg) were measured before and after soccer specific exercise (SAFT90). The reactive strength index (RSI) was determined by a drop jump test, leg stiffness (LS) by a 20 sub-maximal two-legged hopping test, and a functional hamstring to quadriceps strength ratio from isokinetic concentric and eccentric strength of the dominant and non-dominant leg (measured at angular velocities of 1.05 rad · s−1 and 3.14 rad · s−1). Metabolic response to the SAFT90 was determined by blood lactate and perceived exertion was assessed by the Borg scale. After simulated match play, a significant decrease in absolute LS (t = 4.411; p < 0.001; ω2 = 0.48) and relative LS (t = 4.326; p < 0.001; ω2 = 0.49) was observed and the RSI increased significantly (t = 3.806; p = 0.001; ω2 = 0.40). A reduction in LS found after the SAFT90 indicates possible reduction in dynamic knee stabilization. However, if we consider the changes in other observed variables, the present study did not clearly confirm that fatigue induced by a soccer specific protocol increased the risk of ACL and hamstring injury. This may be attributed to the simulated rather than actual match play used in the present study.
Skeletal Muscle Cell Damage Indicators in Volleyball Players after the Competitive Phase of the Annual Training Cycle

Published: June 2018

The aim of the study was to evaluate the impact of the competitive phase on physiological and metabolic indices and selected markers of skeletal muscle damage in male volleyball players. The study group consisted of 24 young male volleyball players. During the study, participants underwent two series of measurements, before and after the competitive phase of the annual training cycle. In both study terms, players performed an incremental treadmill running test to determine their ventilatory threshold and maximal oxygen uptake. Venous and capillary blood samples were taken for biochemical analysis. There was no significant difference in the physical fitness level, values of biochemical variables and the level of antioxidant status in the surveyed athletes between the two study terms. Significant changes within skeletal muscle damage markers were observed between the beginning and the end of the competitive period: an increase in the concentration of cellular DNA damage products (8-hydroxy-2′-deoxyguanosine; p < 0.0001) and a decrease in muscle activity of creatine kinase (p<0.05). In spite of the increment in cell damage markers, the unaffected level of physiological and biochemical markers may indicate that the experienced cell destruction did not negatively affect the level of physical fitness. When designing the annual training plan, coaches and athletes need to take into consideration that temporary physiological states – oxidative stress and inflammation – may be required to attain training adaptation.
How To Maintain Maximal Straight Path Running Speed on a Curved Path in Sprint Events
Authors: Ohnuma Hayato , Tachi Masanobu , Kumano Akihito , Hirano Yuichi
Published: June 2018

This study aims to clarify the ideal technique for running on a curved path during sprinting events. Participants were twelve male track and field athletes including long jumpers and sprinters. The participants performed a 60-m sprint with maximal effort on straight and curved paths. Participants were divided into “good curve runners” and “poor curve runners” according to the curved path running speed relative to that of the straight path. Kinematic variables and ground reaction forces (GRFs) were registered and compared between the groups and paths. The running speed, step length, and flight distance of the outside leg on the curved path were lower than on the straight path only in poor curve runners. The medial-lateral GRF and impulse showed an increase during curved path running for both groups. However, the maximum posterior GRF and impulse decreased only in poor curve runners. The ideal technique for running on a curved path is to maintain the same kinematics and kinetics in the sagittal plane as on a straight path.
A Fast and Robust Way to Estimate Overlap of Niches, and Draw Inference
Authors: Parkinson Judith H. , Kutil Raoul , Kuppler Jonas , Junker Robert R. , Trutschnig Wolfgang , Bathke Arne C.
Published: June 2018

The problem of quantifying the overlap of Hutchinsonian niches has received much attention lately, in particular in quantitative ecology, from where it also originates. However, the niche concept has the potential to also be useful in many other application areas, as for example in economics. We are presenting a fully nonparametric, robust solution to this problem, along with exact shortcut formulas based on rank-statistics, and with a rather intuitive probabilistic interpretation. Furthermore, by deriving the asymptotic sampling distribution of the estimators, we are proposing the first asymptotically valid inference method, providing confidence intervals for the niche overlap. The theoretical considerations are supplemented by simulation studies and a real data example.
NLRP3 in somatic non-immune cells of rodent and primate testes

Published: June 2018

NLRP3 is part of the NLRP3 inflammasome and a global sensor of cellular damage. It was recently discovered in rodent Sertoli cells. We investigated NLRP3 in mouse, human and non-human primate (marmoset and rhesus macaque) testes, employing immunohistochemistry. Sertoli cells of all species expressed NLRP3, and the expression preceded puberty. In addition, peritubular cells of the adult human testes expressed NLRP3. NLRP3 and associated genes (PYCARD, CASP1, IL1B) were also found in isolated human testicular peritubular cells and the mouse Sertoli cell line TM4. Male infertility due to impairments of spermatogenesis may be related to sterile inflammatory events. We observed that the expression of NLRP3 was altered in the testes of patients suffering from mixed atrophy syndrome, in which tubules with impairments of spermatogenesis showed prominent NLRP3 staining. In order to explore a possible role of NLRP3 in male infertility, associated with sterile testicular inflammation, we studied a mouse model of male infertility. These human aromatase-expressing transgenic mice (AROM+) develop testicular inflammation and impaired spermatogenesis during aging, and the present data show that this is associated with strikingly elevated Nlrp3 expression in the testes compared to WT controls. Interference by aromatase inhibitor treatment significantly reduced increased Nlrp3 levels. Thus, throughout species NLRP3 is expressed by somatic cells of the testis, which are involved in testicular immune surveillance. We conclude that NLRP3 may be a novel player in testicular immune regulation.
La fugitiva. Libertad personal, exilio e indiferencia (La fugitiva: Personal Liberty, Exile and Indifference)
Authors: Vargas Vargas José Ángel
Published: June 2018

Se analiza la novela La fugitiva, de Sergio Ramírez Mercado, para determinar cómo se ficcionaliza la vida de Yolanda Oreamuno. Se examinan tres tópicos: la libertad personal, el exilio y la indiferencia. Se explora la elaboración metafórica del personaje Amanda Solano mediante el concepto de libertad personal que se asocia al exilio. Sobre éste, se estudian las particularidades subjetivas y contextuales que lo generan. Por último, se aborda el tema de la indiferencia, asociada al poder y al modo como en Costa Rica se percibe y valora la cultura. Abstract The novel La fugitiva, by Sergio Ramírez-Mercado, is analyzed to determine how this author fictionalizes the life of Yolanda Oreamuno. Three main topics are examined: personal freedom, exile, and indifference. The metaphorical elaboration of the character Amanda Solano is explored, focusing on the concept of personal freedom, as associated with exile. Furthermore, the subjective and contextual peculiarities that generate it are studied. Finally, we address the issue of indifference, related to power and how Costa Rica perceives and values culture.
Una república colosal: la unión de Colombia, el acceso al Pacífico y la utopía del comercio global, 1819-1830
Authors: Afanador-Llach María José
Published: June 2018

Los líderes de la Gran Colombia enfrentaron el problema que suponía imaginar y crear una nación que integrara su gente y un paisaje extenso y montañoso en una entidad política coherente. Para ello, y para justificar la unión de Venezuela, Nueva Granada y Quito, crearon discursos, representaciones y simbolismos que aludían a la geografía. Construyeron además una utopía sobre Colombia como baluarte del comercio global. Tanto en términos simbólicos como prácticos, el acceso al océano Pacífico y la apertura de una conexión interoceánica eran centrales para este proyecto. Esto implicó tensiones entre las economías políticas locales y la legislación diseñada en Bogotá. El eje regional conformado por Guayaquil y Panamá puso a prueba los límites del poder central demostrando la importancia de la región del Pacífico en la experiencia republicana temprana.
Soberana indiferencia. El discurso historiográfico frente al republicanismo popular colombiano
Authors: Gutiérrez Ardila Daniel
Published: June 2018

A pesar de que la consolidación del sistema republicano en la Tierra Firme es inconcebible sin la adhesión entusiasta de las mayorías, el patriotismo popular permanece inexplorado, porque un tenaz prejuicio político actúa como obstáculo cognitivo. La corta Restauración experimentada por la Nueva Granada y los abruptos cambios de régimen que ella supuso llevaron a los contemporáneos, y posteriormente a los historiadores, a endilgar a los humildes una apatía y una indolencia incurables y a ver en los desmanes realistas la clave del cambio político. Las autoridades colombianas tampoco auscultaron la opinión, convencidas de que el republicanismo popular era fruto de una conversión imperfecta y de que el realismo era una dolencia peninsular que solo excepcionalmente afectaba a americanos “desnaturalizados”.
“Todas las cosas tienen su tiempo”. Temporalidad e historia durante la restauración monárquica en la Tierra Firme (1814-1819)
Authors: Chaparro Silva Alexander
Published: June 2018

Este artículo analiza la elaboración del tiempo histórico por parte de los realistas durante la restauración monárquica en la Tierra Firme (1814-1819) con el objetivo de evidenciar cómo la reinvención de la legitimidad del orden monárquico implicó la existencia de un régimen de temporalidades y de historicidades particulares, donde se inscribieron las transformaciones conceptuales del periodo. En un primer momento, daré cuenta de la cohabitación de diversos sentidos de la temporalidad y de las complejas relaciones entre experiencias y expectativas. En segundo lugar, discutiré la escritura de la historia a partir de dos ejemplos concretos: los primeros ensayos de una historia de la crisis monárquica en la Tierra Firme y el debate sobre el significado de la conquista de América y los legados de la colonización hispana. Finalmente, presentaré algunas reflexiones generales.
Ilusiones defraudadas: auge y caída del comercio legal de coca y cocaína en los países andinos
Authors: López Restrepo Andrés
Published: June 2018

Este artículo examina el ciclo de expansión y caída de la producción y el comercio de hoja de coca y cocaína que ocurrió en las últimas décadas del siglo xix y primeras del xx. La globalización, los avances tecnológicos, la industrialización y la publicidad fueron los factores que impulsaron el auge de esas dos drogas, pero su caída se debió a razones no económicas, de tipo sanitario, religioso y de política internacional. Quienes resultaron ganadores de esa expansión fueron algunos países desarrollados y un país andino, Perú. Colombia cultivaba coca, pero se mantuvo al margen de la bonanza, mientras que Bolivia participó de manera marginal. La coca y la cocaína han pasado por un nuevo auge a partir de la década de 1970, pero en condiciones de ilegalidad.

La obra titulada La batalla de los siglos. Estado, Iglesia y religión en Colombia en el siglo xix. De la Independencia a la Regeneración del profesor José David Cortés Guerrero, constituye un exhaustivo análisis y una nueva lectura de las relaciones Estado-Iglesia en Colombia durante el siglo xix. El libro se encuentra compuesto por una introducción, cinco partes y las conclusiones. En el capítulo introductorio, Cortés explica cómo el Estado y la Iglesia se reconformaron desde la Independencia hasta la Regeneración a medida que fueron presentándose nuevas realidades políticas, ideológicas, económicas y culturales que influyeron en la Iglesia Católica. Desarrolla las cinco partes de su obra partir de seis hipótesis. La primera tiene que ver con las interpretaciones que elaboraron los historiadores liberales y conservadores del siglo xix sobre la Iglesia, el Estado y la religión, las cuales para Cortés aún no han sido superadas por los historiadores contemporáneos. La segunda, muy cercana a la primera, hace referencia a la periodicidad de los hitos fundacionales elaborados por los historiadores decimonónicos. La tercera muestra la imposibilidad de entender el Estado y la Iglesia sin profundizar en el patronato republicano y la aceptación de la independencia por parte de la Santa Sede. La cuarta argumenta que el naciente Estado, al querer ser moderno, se enfrentó a un mundo tradicional en el que la Iglesia jugaba un papel primordial en el control sociopolítico y económico. La quinta muestra el papel de la religión. Según Cortés, los procesos de la romanización y el ultramontanismo, entre otros, contradicen la interpretación de que en el siglo xix la religión fue desplazada de su función de fuente de identidad y de sentimiento. La sexta argumenta que existe una conexión entre los procesos históricos internos de Colombia y los que sucedían en Occidente.
Earthquake design of flexible soil-retaining structures
Authors: Wood John H.
Published: June 2018

Many soil-retaining wall structures are restrained from outward sliding movements and because of this it may not be appropriate to use the commonly applied Mononobe–Okabe (MO) method to estimate the earthquake induced pressures on them. This semi-rigid or stiff wall category includes bridge abutments, building basement walls and hydraulic structures associated with hydro-power and flood control. In the present research, finite-element analyses have been completed on cantilever walls that deform by both rotation about their base and flexure in the wall stem. The wall stiffness parameters have been varied to produce pressure distributions under earthquake and gravity loads for walls that vary from rigid to sufficiently flexible for the MO method to be applicable. The paper summarises the results of these finite-element studies. An example is presented to demonstrate how the results can be applied in the earthquake design of semi-rigid or stiff walls.
Purification of Cafeteria roenbergensis virus particles v1
Authors: Fischer Matthias
Published: June 2018

The concentration and purification of giant DNA viruses from bacteria-containing cultures can present problems because the particle size of giant viruses overlaps with that of smaller bacteria, hence filtration as the only separation method is not possible. In this protocol, a combination of centrifugation, tangential flow filtration, and density-gradient ultracentrifugation is used to concentrate and purify particles of the giant marine virus CroV that infects the heterotrophic flagellate Cafeteria roenbergensis.
VIEWING HABITS AND IDENTIFICATION WITH TELEVISION CHARACTERS AMONG AT-RISK AND NORMATIVE CHILDREN AND ADOLESCENTS
Authors: Cohen Zilka Gila , Romi Shlomo
Published: June 2018

This study examined the relationship between participants’ negative or positive identification with television characters and their behavior, and how their reactions in times of anger — whether simply negative or physically violent — varied between at-risk participants and normative ones. Participants were 86 children and adolescents from Israel who filled in four questionnaires on the topics of viewing habits, attitudes, self-image, and aggression. The findings revealed that at-risk children and adolescents reacted with more anger than did their normative counterparts, and that their reaction became stronger when they identified with a character’s negative behavior. It was further revealed that the more they watched, the higher their identification with the character and the greater their negative reaction during anger. A violent physical reaction in times of anger is more strongly associated with viewing alone than with viewing with friends. The findings also revealed that identification with the character is a mediating variable between the amount and type (solitary or with friends) of viewing and negative and violent reactions. At-risk children and adolescents tend to choose programs that show violent behaviors, and such programs could ultimately lead them to exhibit violent reactions. The question is how can the amount of children and adolescents’ viewing be limited while avoiding arguments and punishment? The key to success is finding a solution that will be formulated with the children and adolescents’ full cooperation.
Terminology for Librarian Help on the Home Page
Authors: Matthews Leni
Published: June 2018

A usability study was run to validate terminology (labels) for seeking librarians from the UTA Libraries homepage. Seven new labels were proposed by librarians. They hoped these labels would help users in finding them and discovering librarians various skills to meet users' needs.

Students were presented with a paper prototype of the library's homepage that included the seven proposed labels. They were asked to find information using two search goals as it related to seeking assistance from a librarian.

Phytosociological description of mesophilous colline-submontane Fagus sylvatica and Carpinus betulus forests in Slovenian Istria
Authors: Dakskobler Igor , Sadar Zvone
Published: June 2018

A phytosociological analysis of 46 relevés of mesophilous colline and submontane Fagus sylvatica as well as (or) Carpinus betulus forests was conducted in Slovenian Istria. It was established that they are frequently syndynamically interrelated: in places, common hornbeam stands are merely a degradation stage on beech sites, and can be classified into the subassociation Ornithogalo pyrenaici-Fagetum fraxinetosum orni (its locus classicus is in the Goriška Brda Hills) and into the new subassociation Ornithogalo pyrenaici-Carpinetum betuli seslerietosum autumnalis. Compared with similar submontane stands from other parts of the western and southwestern Slovenia they are slightly poorer in species, with fewer diagnostic species of alliances Erythronio-Carpinion, Aremonio-Fagion and Tilio-Acerion, order Fagetalia sylvaticae and class Vaccinio-Piceetea, and with more diagnostic species of the order Quercetalia pubescenti-petraeae. Geographically, they are characterised by the taxon Helleborus odorus subsp. istriacus. Although they cover small areas these forests generate high yields and are therefore important both economically and as biotopes of protected species.
Stress-Dependent Perforation in Carbonate Rocks: An Experimental Study
Authors: Norouzi Peyman , Hashemolhosseini Hamid , Baghbanan Alireza
Published: June 2018

Perforation with shaped charges as a conventional well-completion technique is widely used in the oil industry. Different phenomena influence perforation performance and depth of penetration (DOP). The authors examined the effect of in-situ stresses and shot density on DOP and created fracture patterns in concrete and limestone samples with surface and polyaxial/triaxial-stress-loading conditions. To achieve this aim, we designed and developed a polyaxial-perforation test machine. We optimized the number of experimental tests using the Taguchi-design test method. The Taguchi orthogonal scheme is well-known and is a highly recommended method to optimize the number of required experiments (Taguchi 1990; Ross 1996; Jeyapaul et al. 2005; Gupta et al. 2014). Our experimental setup resembles vertical wells in the strike/slip-faulting regions and horizontal wells in the reverse-faulting regions. The results show that DOP is more controlled by stresses normal to the shooting direction in polyaxial tests than by the stress in the direction of penetration. DOP and the maximum hole diameter from the second charge had a direct relation with shot density. The DOP observed in polyaxial-loading conditions was a little lower than in the triaxial-loading mode, where the mean value of stresses normal to the shooting direction in the polyaxial tests was the same as the horizontal stresses in the triaxial tests. In both surface and triaxial-loading conditions, the patterns of perforation fractures were radial and regular, whereas the cracks created were oriented along the direction of maximum horizontal stress in the polyaxial tests.

Published: June 2018

It is a problem of spectra analysis of flue gas that how to separate and calculate the concentration of different kinds of gas from continuous mixed gas absorption spectrum signal. So based on experimental data, a new iteration of the circular algorithm is put forward on the basis of Lambert-Beer’s law. This algorithm, using the superposition of the absorbance, makes data nonlinear fitting. It takes the advantages of the wavelength optimum and the circular iteration to distinguishing the gas mixture of different composition. Experimental results show that: this method can at once calculate a variety of harmful gas concentration and accuracy up to ± 3%. it has strong anti-jamming capability and is suitable for practical application of engineering.

With the rapid growth of air transportation, capital is becoming increasingly scarce, and the abnormal situation of flight is becoming more and more serious. Irregular flights have become popular in society, and it is also a great difficulty for airlines. Flight recovery is a classic NP problem. It is of great theoretical significance and practical value to study flight restoration problem. The punctuality of the airline’s schedule is a key factor in retaining current customers and attracting new passengers. However, because the civil aviation transportation system is very complex, many reasons will cause the flight plan can not be carried out normally. Weather, air traffic flow control, airport security check, passenger’s own reasons and temporary shortage of crew cause the flight can’t be executed normally, that is, abnormal flight or flight interruption. Flight interruption will affect the normal operation of airlines. Some flights have to be cancelled or delayed, which will cause huge economic losses to airlines. Besides, the delay or cancellation of flights will cause great inconvenience to passengers and affect the reputation of airlines. The operation control and management level of abnormal flights has attracted more and more attention from domestic airlines. Optimization control and algorithm design have also become a hot topic in the research of abnormal flights in China. Based on the further understanding of the NP problem, this paper verifies the feasibility of the greedy random adaptive search algorithm GRASP algorithm in the NP problem solving process under the flight recovery problem model. According to the analysis, the resource allocation model is established to verify the shortcomings of Lagrange relaxation algorithm (LRS) in flight recovery problem. Meanwhile, the greedy random adaptive search algorithm (GRASP) is used to solve the model, and the new flight schedule is obtained. Through the experimental results, the feasibility of the algorithm is proved in the error range.
