Das ›Goldene Zeitalter‹ im modernen Spanien
Authors: Schreckenberg Stefan
Published: April 2020

Speaking of a ›Golden Age‹ or a Siglo de Oro in reference to Spanish history, culture and literature transforms an ancient myth into a historiographical concept, which seems rather problematical, even contradictory, and at the same time, seen in a wider European context, exceptional. Nevertheless, the Siglo de Oro is still being used not only as a key term in contemporary academic works – inside and outside Spain – on the Early Modern period, but also as a highly controversial idea in political and ideological debates, especially on behalf of what may or may not be Spanish identity.
This article seeks to give a brief overview of the discussions that try to define the concept of the Siglo de Oro and to present the literary canon as well as the ideological implications linked to it. Starting in the aftermath of the epoch itself, in other words the 18th century, it focuses on the convergence of the political and aesthetical discussions that oppose the ›Two Spains‹ during the 20th century in terms of how to choose and interpret their ›classics‹. Finally, it tries to give a (necessarily incomplete) view on the actual situation, where the Golden Age myth still interferes not only in literary but also in socio-political debates.
Bajla Gelblung und Johannes Bobrowskis Gedicht BERICHT
Authors: Müller Eduard R.
Published: April 2020

Johannes Bobrowski’s iconic poem BERICHT (REPORT) refers to an historical photograph showing the interrogation of a young Polish Jewish woman by officers of the German Wehrmacht in Brest-Litovsk. It has long been assumed that the woman referred to as Bajla Belblung was a resistance fighter who escaped from the Warsaw ghetto in 1943. But further research has shown that the interrogation took place in September 1939 after the end of the third week of the war. This work examines the historical background of the photos of Bajla Gelblung taken at that time as well how the photograph captions have changed over time. It also raises questions about the development of a legend, to which Bobrowski’s poem has made a decisive contribution.
Erzählend erinnern
Authors: Rhinisperger Selena
Published: April 2020

This paper analyses how Heinrich von dem Türlin creates a metadiscourse about generic issues and conventions of Arthurian tales in his Romance Diu Crône by outlining the importance of narration itself for the Arthurian court. Based on two scenes where first the Arthurian court and than Gawein as main character of the tale are on the verge of forgetting themselves, the anaysis shows how processes of telling one’s own story are crucial not only for memoria but even for one’s own existence. By shifting these observations from the level of the narrated world to the narration itself the close connections between telling and being can be understood as an implicit theory of performative narration.

Published: April 2020

Objective: The objective of study was to find out serum uric acid level in normal andpreeclamptic pregnant women of third trimester visiting outpatient department of obstetrics and gynecology of Bahawal Victoria Hospital, Bahawalpur.
Methodology: It was a cross sectional descriptive study conducted form July 2018 to June 2019. All primigravida women of age 18-35 years in third trimester of singleton pregnancy attending in Obstetrics and Gynecology Outpatient Department of Bahawal Victoria Hospital in study duration were included in the study. Statistical analysis was performed by using SPSS version 14. Chi-square test was performed to find the statistical difference regarding uric acid distribution between groups and ‘p’ value <0.05 was considered as a lowest level of significance.
Results: Out of total 1212 women 84.6% were normal and 15.4% had preeclampsia. In our study out of 187 preeclamptic women, 63.6% had raised serum uric acid level and out of 268 normal pregnant women uric acid level was raised in only 39.5%. Results were found statistically significant.
Conclusion: Results of our study suggest that serum uric acid level in pregnant women can be used as a useful and inexpensive marker in prediction of preeclampsia and preventive measures can be taken accordingly.

The death of Jack Adcock in 2011 made headlines all around the world for many reasons. He was a 6-year-old child, admitted to Leicester Royal Infirmary (LRI) in February 2011 who died of sepsis and pneumonia 11 hours later. The paediatric registrar Dr. Hadiza Bawa-Garba had failed to diagnose his condition, resulting in criminal proceedings and her erasure from the medical register in 2017. This article gives a glimpse of the controversial case, tries to relate this to all medical specialties, and offers some guidance on how to avoid a similar situation developing.
A Comparison of Properties of Quasars with and without Rapid Broad Absorption Line Variability
Authors: Horiuchi Takashi , Morokuma Tomoki , Misawa Toru , Hanayama Hidekazu , Kawaguchi Toshihiro
Published: April 2020

We investigate the correlation between rest-frame UV flux variability of broad absorption line (BAL) quasars and their variability in BAL equivalent widths (EWs) in a various timescale from <10 days to a few years in the quasar rest frame. We use the data sets of BAL EWs taken by the Sloan Digital Sky Survey Reverberation Mapping project and photometric data taken by the intermediate Palomar Transient Factory in the g and R bands and the Panoramic Survey Telescope and Rapid Response System in grizy bands. Our results are summarized as follows: (1) the distributions of flux variability versus BAL variability show weak, moderate, or a strong positive correlation; (2) there is no significant difference in flux variability amplitudes between BAL quasars with significant short timescale EW variability (called class S1) and without (class S2); (3) in all timescales considered in this paper, the class S1 quasars show systematically larger BAL variability amplitudes than those of the class S2 quasars; and (4) there are possible correlations between BAL variability and physical parameters of the quasars such as black hole masses (moderate positive), Eddington ratios, and accretion disk temperature (strong negative) in the class S2 quasars. These results indicate that the BAL variability requires changing in the ionizing continuum and an ancillary mechanism such as variability in X-ray shielding gas located at the innermost region of an accretion disk.
Astrophysical Insights into Radial Velocity Jitter from an Analysis of 600 Planet-search Stars
Authors: Luhn Jacob K. , Wright Jason T. , Howard Andrew W. , Isaacson Howard
Published: April 2020

Radial velocity (RV) detection of planets is hampered by astrophysical processes on the surfaces of stars that induce a stochastic signal, or “jitter,” which can drown out or even mimic planetary signals. Here, we empirically and carefully measure the RV jitter of more than 600 stars from the California Planet Search sample on a star by star basis. As part of this process, we explore the activity–RV correlation of stellar cycles and include appendices listing every ostensibly companion-induced signal we removed and every activity cycle we noted. We then use precise stellar properties from Brewer et al. to separate the sample into bins of stellar mass and examine trends with activity and with evolutionary state. We find that RV jitter tracks stellar evolution and that in general, stars evolve through different stages of RV jitter: the jitter in younger stars is driven by magnetic activity, while the jitter in older stars is convectively driven and dominated by granulation and oscillations. We identify the “jitter minimum”—where activity-driven and convectively driven jitter have similar amplitudes—for stars between 0.7 and 1.7 M
⊙ and find that more-massive stars reach this jitter minimum later in their lifetime, in the subgiant or even giant phases. Finally, we comment on how these results can inform future RV efforts, from prioritization of follow-up targets from transit surveys like TESS to target selection of future RV surveys.
Heating and Eruption of a Solar Circular-ribbon Flare
Authors: Lee Jeongwoo , Karpen Judith T. , Liu Chang , Wang Haimin
Published: April 2020

We studied a circular-ribbon flare, SOL2014-12-17T04:51, with emphasis on its thermal evolution as determined by the differential emission measure (DEM) inversion analysis of the extreme ultraviolet (EUV) images of the Atmospheric Imaging Assembly instrument on board the Solar Dynamics Observatory. Both temperature and emission measure start to rise much earlier than the flare, along with an eruption and formation of a hot halo over the fan structure. In the main flare phase, another set of ribbons forms inside the circular ribbon, and expands as expected for ribbons at the footpoints of a postflare arcade. An additional heating event further extends the decay phase, which is also characteristic of some eruptive flares. The basic magnetic configuration appears to be a fan–spine topology, rooted in a minority-polarity patch surrounded by majority-polarity flux. We suggest that reconnection at the null point begins well before the impulsive phase, when the null is distorted into a breakout current sheet, and that both flare and breakout reconnection are necessary in order to explain the subsequent local thermal evolution and the eruptive activities in this confined magnetic structure. Using local DEMs, we found a postflare temperature increase inside the fan surface, indicating that the so-called EUV late phase is due to continued heating in the flare loops.
Burst Properties of the Most Recurring Transient Magnetar SGR J1935+2154
Authors: Lin Lin , Göğüş Ersin , Roberts Oliver J. , Kouveliotou Chryssa , Kaneko Yuki , van der Horst Alexander J. , Younes George
Published: April 2020

We present timing and time-integrated spectral analysis of 127 bursts from SGR J1935+2154. These bursts were observed with the Gamma-ray Burst Monitor on the Fermi Gamma-ray Space Telescope and the Burst Alert Telescope on the Neil Gehrels Swift Observatory during the source’s four active episodes from 2014 to 2016. This activation frequency makes SGR J1935+2154 the most burst prolific transient magnetar. We find the average duration of all the detected bursts to be much shorter than the typical, anticipated value. We fit the burst time-integrated spectra with two blackbody functions, a Comptonized model and three other simpler models. Bursts from SGR J1935+2154 exhibit similar spectral properties to other magnetars, with the exception of the power-law index from the Comptonized model, which correlates with burst fluence. We find that the durations and both blackbody temperatures of the bursts have significantly evolved across the four active episodes. We also find that the burst time history exhibits two trends, which are strongly correlated with the decay of the persistent emission in each outburst.
Swift Spectroscopy of the Accretion Disk Wind in the Black Hole GRO J1655–40

Published: April 2020

Chandra obtained two High Energy Transmission Grating spectra of the stellar-mass black hole GRO J1655−40 during its 2005 outburst, revealing a rich and complex disk wind. Soon after its launch, the Neil Gehrels Swift Observatory began monitoring the same outburst. Some X-ray Telescope (XRT) observations were obtained in a mode that makes it impossible to remove strong Mn calibration lines, so the Fe Kα line region in the spectra was previously neglected. However, these lines enable a precise calibration of the energy scale, facilitating studies of the absorption-dominated disk wind and its velocity shifts. Here we present fits to 15 Swift/XRT spectra, revealing variability and evolution in the outflow. The data strongly point to a magnetically driven disk wind: both the higher-velocity (e.g.,

) and lower-velocity (e.g.,

) wind components are typically much faster than is possible for thermally driven outflows (

), and photoionization modeling yields absorption radii that are two orders of magnitude below the Compton radius that defines the typical inner extent of thermal winds. Moreover, correlations between key wind parameters yield an average absorption measure distribution that is consistent with magnetohydrodynamic wind models. We discuss our results in terms of recent observational and theoretical studies of black hole accretion disks and outflows, as well as future prospects.
Constraint on the Ejecta Mass for Black Hole–Neutron Star Merger Event Candidate S190814bv
Authors: Kawaguchi Kyohei , Shibata Masaru , Tanaka Masaomi
Published: April 2020

We derive the upper limit to the ejecta mass of S190814bv, a black hole–neutron star (BH–NS) merger candidate, through radiative transfer simulations for kilonovae with realistic ejecta density profiles, as well as detailed opacity and heating rate models. The limits to the ejecta mass strongly depend on the viewing angle. For the face-on observations (≤45°), the total ejecta mass should be smaller than 0.1 M
⊙ for the average distance of S190814bv (D = 267 Mpc), while a larger mass is allowed for the edge-on observations. We also derive the conservative upper limits of the dynamical ejecta mass to be 0.02, 0.03, and 0.05 M
⊙ for the viewing angles ≤20°, ≤50°, and ≤90°, respectively. We show that an iz-band observation deeper than 22 mag within 2 days after the gravitational-wave trigger is crucial to detect a kilonova with a total ejecta mass of 0.06 M
⊙ at a distance of D = 300 Mpc. We also show that a strong constraint on the NS mass–radius relation can be obtained if future observations put an upper limit of 0.03 M
⊙ on the dynamical ejecta mass for a BH–NS event with a chirp mass smaller than ≲3 M
⊙ and effective spin larger than ≳0.5.
Gamma-Ray Flares in the Long-term Light Curve of 3C 454.3
Authors: Das Avik Kumar , Prince Raj , Gupta Nayantara
Published: April 2020

3C 454.3 is frequently observed in the flaring state. The long-term light curve of this source has been analyzed with 9 yr (2008 August–2017 July) of data from the Fermi-LAT detector. We have identified five flares and one quiescent state. The flares have substructures with many peaks during the flaring phase. We have estimated the rise and decay time of the flares and compared with flares of other similar sources. The modeling of gamma-ray spectral energy distributions shows in most cases that a log-parabola function gives the best fit to the data. We have done time-dependent leptonic modeling of two of the flares, for which simultaneous multiwavelength data are available. These two long-lasting flares, Flare-2A and Flare-2D, continued for 95 and 133 days, respectively. We have used the average values of Doppler factor, injected luminosity in electrons, size of the emission region, and the magnetic field in the emission region in modeling these flares. The emission region is assumed to be in the broad-line region in our single-zone model. The energy losses (synchrotron, synchrotron self-Compton, external Compton) and escape of electrons from the emission region have been included while doing the modeling. Although the total jet powers required to model these flares with the leptonic model are higher compared to other sources, they are always found to be lower than the Eddington luminosity of 3C 454.3. We also select some flaring peaks and show that the time variation of the Doppler factor or the injected luminosity in electrons over short timescales can explain their light curves.

We consider the body of published distance moduli to the Fornax and Coma galaxy
clusters, with specific emphasis on the period since 1990. We have carefully
homogenized our final catalogs of distance moduli onto the distance scale
established in the previous papers in this series. We assessed systematic
differences associated with the use of specific tracers and consequently
discarded results based on application of the Tully–Fisher relation and of
globular cluster and planetary nebula luminosity functions. We recommend
“best” weighted relative distance moduli for the Fornax and Coma
clusters with respect to the Virgo cluster benchmark of

mag and

where the first distance modulus for each cluster is the result
of our analysis of the direct, absolute distance moduli, while the second
modulus is based on distance moduli relative to the Virgo cluster. While the
absolute and relative distance moduli for both clusters are mutually consistent
within the uncertainties, the relative distance moduli yield shorter absolute
distances by ∼1σ. It is unclear what may have caused
this small difference for both clusters; lingering uncertainties in the
underlying absolute distance scale appear to have given rise to a systematic
uncertainty of the order of 0.20 mag.

Authors: Cheli Gabriela Roiko , Giusti Gabriela , Togawa Letícia Yuriko , Silva Diogo Aparecido Lopes , Tadano Yara De Souza
Published: April 2020

A atividade industrial é uma das principais causadoras de impactos ao meio ambiente, especialmente quanto à formação de material particulado ao ar. Uma forma de considera-los é usando a técnica de Avaliação do Ciclo de Vida, que objetiva analisar o ciclo de vida envolvido em um produto ou processo e associar os impactos causados em cada uma das etapas desse ciclo. Essa técnica tem quatro fases, sendo a fase de Avaliação de Impacto do Ciclo de Vida (AICV) abordada neste trabalho. Nela, relacionam-se os impactos com cada resultado da fase de Inventário do Ciclo de Vida, por meio de modelos de caracterização. Esses modelos objetivam calcular um fator de caracterização (FC), que irá mensurar o nível de impacto dentre as categorias de impacto existentes. Este trabalho tem como foco avaliar modelos de caracterização para a categoria de formação de material particulado, a fim de identificar os modelos mais adequados para serem utilizados no Brasil. A análise foi realizada dividindo o FC no fator de inalação e fator de efeito, sendo o último foco deste estudo. Três modelos foram analisados e os demais modelos existentes serão analisados posteriormente e avaliados quantitativamente, a fim de recomendar os mais adequados a serem aplicados no Brasil. Com isso, permite-se um avanço científico nas pesquisas de AICV no Brasil, além de possibilitar resultados mais próximos à realidade nacional.
Proposta alternativa para a adequação dos pequenos municípios à PNRS, baseada em sistema de produto-serviço
Authors: Alves de Carvalho Jairo Pablo , Borsato Milton
Published: April 2020

O Governo brasileiro lançou, em 2010, a Política Nacional de Resíduos Sólidos (PNRS), com o objetivo de estabelecer diretrizes e normatizar boas práticas de gerenciamento dos resíduos sólidos urbanos. Dentre as metas traçadas, estava a de acabar com os depósitos a céu aberto (lixões) em todos os municípios brasileiros. Contudo mais de um terço ainda não se adequou, mormente por não ter orçamento para custear as soluções tecnológicas disponíveis. Algumas administrações têm optado pelo consórcio intermunicipal para ganharem massa crítica e poderem utilizar as tecnologias existentes. Mas esta estratégia implica na transferência de passivo ambiental e social para o município sede do empreendimento, cujo território receptará o lixo dos demais, levando a desvalorização imobiliária na região. Uma solução utilizada com relativo sucesso em países asiáticos tem sido o uso de biodigestores de pequeno porte. Mas a solução apresenta alta taxa de abandono, devido a carência de serviços de suporte como treinamento de instaladores e usuários, atendimento ao consumidor, suporte técnico e manutenção. Este artigo apresenta a proposta dum sistema produto-serviço (PSS), projetado para mitigar as debilidades do modelo asiático, a qual elimina a etapa de transporte do lixo, como alternativa para os pequenos municípios brasileiros adequarem-se à PNRS.
Cidades inteligentes e cidades sustentáveis: convergência de ações ou mera publicidade?
Authors: Proença Junior Milton , Duenhas Rogério Allon
Published: April 2020

Este artigo pretende identificar se as cidades inteligentes então contribuindo para o desenvolvimento de cidades sustentáveis. A pesquisa se concretizou numa revisão integrativa de literatura, com base nos termos “cidade inteligente” e “cidade sustentável”, realizada nas bases indexadas no Portal de Periódicos da CAPES que atendessem aos critérios: artigos, em português ou inglês, publicados no ano de 2014 a 2018, revisados por pares, que expusessem em sua discussão ponderações sobre cidades inteligentes e cidades sustentáveis. A busca inicial resultou em 80 artigos, que após passar pelos critérios de inclusão e exclusão, resultaram em 07 artigos inclusos à revisão. Os resultados apontam, inicialmente, pela necessidade de amadurecimento dos conceitos de cidade inteligente e cidade sustentável. Há indícios de carência de indicadores para uma aferição realista do desenvolvimento sustentável em cidades inteligentes. O uso de TIC parece ser o caminho mais indicado no alcance de cidades sustentáveis, porém a efetividade dessas ações ainda é questionável. Para trabalhos futuros sugere-se que aprofundem no estudo de metodologias de avaliação de indicadores de sustentabilidade em cidades inteligentes; que se apresentem propostas de construção ao conceito de “cidades inteligentes sustentáveis”; e que aborde o papel do cidadão no desenvolvimento de “cidades inteligentes sustentáveis”.

In support of a biological control program in California, USA, against the bagrada bug,Bagrada hilaris(Burmeister) (Hemiptera, Pentatomidae), an invasive pest of Asian origin, colonies of two species ofOoencyrtusAshmead (Hymenoptera, Encyrtidae) are maintained usingB. hilariseggs as host. One of them,Ooencyrtus mirusTriapitsyn & Power,sp. nov., is of Pakistani origin. It displays natural preference for bagrada bug eggs and is being evaluated in quarantine as a candidate for classical biological control. The other,Ooencyrtus lucidusTriapitsyn & Ganjisaffar,sp. nov., appears to be native to California, and we believe it switched toB. hilarisfrom native pentatomid hosts. Both new species are described and illustrated, as is the Old World speciesOoencyrtus telenomicida(Vassiliev), for which a neotype is designated. The presented morphometric evidence as well as mitochondrial and nuclear ribosomal DNA sequence data separateOoencyrtus mirusfromO. telenomicida. A lectotype is designated forOoencyrtus californicusGirault from California, which is morphologically similar toO. lucidus.

Published: April 2020

The tourism industry has become more competitive with recent developments in information technology. This has assisted tourists to select the best tourist destination, often those providing the highest standard of services within a reasonable price range. This objective of this study was to develop a framework of tourism indicators that drive destination competitiveness, using a systematic review methodology. Research has confirmed that the tourism industry is more susceptible to events influencing its competitiveness than any other sectors of the economy. The interpretivistic research paradigm with qualitative methodology data was followed. A systematic review of the available literature both contemporary and secondary data on was collected. Once the collected data was sourced and sorted according to the inclusion and exclusion criteria, the information was analysed using thematic analysis. The thematic analysis identified three themes, each holding sub-themes indicative to tourism indicators which influence destination competitiveness namely: 1) core-indicators, 2) facilitating-indicators and 3) supporting indicators. A proposed dimensional framework of destination competitiveness indicators was developed, which could aid researchers to investigate the socioeconomic dynamics that may be functional between developed and developing countries.

OTONOMI DAERAH DAN OTONOMI PENDIDIKAN
Authors: Inom Nasution
Published: April 2020

Reformasi yang terjadi di Indonesia telah mengakibatkan pergeseran penyelenggaraan pemerintahan dari sentralisasi ke desentralisasi. Pergeseran ke desentralisasi membuat daerah memiliki otonomi penuh. Hasil yang diharapkan dari pelaksanaan otonomi dan desentralisasi ialah semakin optimalnya pengelolaan sekolah dan makin meningkatnya kualitas pendidikan. Namun, dalam perjalanan awal otonomi daerah yang meliputi juga otonomi pendidikan muncul fenomena berdampak semakin dinomorduakan pendidikan. Hal itu dapat dilihat dari semakin melemahnya kualitas pendidikan. Sebenarnya komponen pendidikan merupakan komponen utama pembangunan daerah. Untuk meningkatkan kualitas sumber daya manusia di daerah, pendidikan harus menjadi ujung tombak pembangunan daerah. Upaya peningkatan mutu pendidikan melalui otonomi daerah mencakup antara lain sarana prasarana, kesejahtaraan guru, rekrutmen guru dan penempatan guru, kurikulum, peran serta masyarakat, serta dana operasional.

Ekosistem terumbu karang memiliki arti yang sangat penting bagi kehidupan manusia, baik dari segi ekonomi maupun sebagai penunjang kegiatan rekreasi karena keindahannya. Terumbu karang tersebar di seluruh dunia dan mencakup lebih dari 100 negara, termasuk Indonesia, dengan luas diperkirakan mencapai 600.000 km2. Mulai dekade 1990-an, para ahli mulai mengangkat isu tentang semakin memburuknya kondisi terumbu karang dunia, antara lain Indonesia. Saat ini diperkirakan 10% dari terumbu karang dunia dalam kondisi sangat rusak dan bahkan kemungkinan tidak dapat dipulihkan kembali. Dalam kurun waktu 20 tahun mendatang, apabila tidak ada upaya pelestarian yang intensif, maka diperkirakan 30% dari terumbu karang yang ada akan mengalami nasib yang sama.
