Authors: Soko Geofrey F. , Burambo Anthony B. , Mngoya Mpanda M. , Abdul Burhani A.
Published: November 2019

PURPOSE

Misconceptions associated with radiotherapy (RT) may affect the patient’s choice to undergo or not undergo RT. In this study, the level of awareness and perceptions about radiation and RT, as well as their impact on the use of RT, were assessed.

MATERIALS AND METHODS

A cross-sectional survey was conducted in the city of Dar es Salaam, Tanzania, between November 2018 and March 2019. Stratified sampling was used to obtain a sample of 629 participants from 4 strata, including 53 patients with cancer, 129 health professionals, 127 medical and nursing students, and 320 respondents from the general public. A questionnaire with 13 items measuring awareness and 8 items measuring perceptions was used for data collection. The Kruskal-Wallis test and χ2 test were used to test association between predictor and outcome variables. Statistical analyses were performed using statistical software.

RESULTS

The percentage of right responses was < 50% in all 13 awareness items. Only 16.9% of respondents were aware that RT would not reduce their lifespan. Only 34.5% of respondents had positive perceptions of RT. Awareness was higher among medical/nursing students, younger respondents, single or cohabiting respondents, and those who had attained a college or higher education. Overall, 52% would accept receiving RT if recommended as part of their treatment. Those who would accept undergoing RT were more likely to have higher awareness and a positive perception of RT.

CONCLUSION

Public awareness of RT in Dar es Salaam is low, and negative perceptions prevail. Low levels of awareness and negative perceptions have a negative effect on the use of RT.

Published: November 2019

BACKGROUND:

Pulmonary complications related to residual neuromuscular blockade lead to morbidity and mortality. Using an interrupted time series design, we tested whether proportions of reintubation for respiratory failure or new noninvasive ventilation were changed after a system-wide transition of the standard reversal agent from neostigmine to sugammadex.

METHODS:

Adult patients undergoing a procedure with general anesthesia that included pharmacologic reversal of neuromuscular blockade and admission ≥1 night were eligible. Groups were determined by date of surgery: August 15, 2015 to May 10, 2016 (presugammadex), and August 15, 2016 to May 11, 2017 (postsugammadex). The period from May 11, 2016 to August 14, 2016 marked the institutional transition (washout/wash-in) from neostigmine to sugammadex. The primary outcome was defined as a composite of reintubation for respiratory failure or new noninvasive ventilation. Event proportions were parsed into 10-day intervals in each cohort, and trend lines were fitted. Segmented logistic regression models appropriate for an interrupted time series design and adjusting for potential confounders were utilized to evaluate the immediate effect of the implementation of sugammadex and on the difference between preintervention and postintervention slopes of the outcomes. Models containing all parameters (full) and only significant parameters (parsimonious) were fitted and are reported.

RESULTS:

Of 13,031 screened patients, 7316 patients were included. The composite respiratory outcome occurred in 6.1% of the presugammadex group and 4.2% of the postsugammadex group. Adjusted odds ratio (OR) and 95% confidence intervals (CIs) for the composite respiratory outcome were 0.795 (95% CI, 0.523–1.208) for the immediate effect of intervention, 0.986 (95% CI, 0.959–1.013) for the difference between preintervention and postintervention slopes in the full model, and 0.667 (95% CI, 0.536–0.830) for the immediate effect of the intervention in the parsimonious model.

CONCLUSIONS:

The system-wide transition of the standard pharmacologic reversal agent from neostigmine to sugammadex was associated with a reduction in the odds of the composite respiratory outcome. This observation is supported by nonsignificant within-group time trends and a significant reduction in intercept/level from presugammadex to postsugammadex in a parsimonious logistic regression model adjusting for covariates.
Use of Virtual Reality as a Surrogate for Parental Presence During Anesthetic Induction: A Case Report
Authors: Gupta Abhinav , Joseph Thomas James
Published: November 2019

Virtual reality (VR), a computer-generated simulation of a 3-dimensional environment, is a relatively new method of providing distraction before and during procedures. We describe the use of a VR multiuser application, Oculus Rooms, to calm an anxious 10-year-old boy during transportation to the operating room and induction of anesthesia. The use of VR could lessen the perioperative anxiety of children by maintaining a virtual child-parent connection while avoiding the potential drawbacks to having parents actually in the operating room before and during induction of anesthesia. The success of this novel technique has important implications for future clinical trials and practice.
Severe and Prolonged Hypotension After Oral 5-Aminolevulinic Acid Administration in a Patient With End-Stage Renal Disease Undergoing Transurethral Resection of a Bladder Tumor: A Case Report
Authors: Kida Tatsuya , Kobashi Teisei , Usuda Yutaka , Kobayashi Kazuki , Sumitomo Masakazu
Published: November 2019

A 72-year-old man with end-stage renal disease (ESRD) undergoing transurethral resection of a bladder tumor experienced severe and prolonged hypotension after receiving oral 5-aminolevulinic acid (5-ALA). Continuous infusions of norepinephrine and vasopressin ultimately resolved the hypotension over the course of 26 hours. It is uncertain whether 5-ALA is causative or is a contributing factor that influences other factors, such as hypovolemia after hemodialysis and autonomic nerve dysfunction associated with ESRD. Our findings suggest that anesthesiologists should be aware of the possible occurrence of hypotension after administration of 5-ALA, and urologists should consider intravesical 5-ALA administration in patients with ESRD.

Published: November 2019

Winter swimming is a stressful condition of whole-body exposure to cold water; however, winter swimmers have achieved variable degrees of adaptation to cold. The question arises whether this extreme sport activity has any health benefits or whether it may confer potentially harmful effects. As a form of aerobic exercise, albeit more strenuous when performed in cold water, winter swimming may increase body tolerance to stressors and achieve body hardening. When practiced by individuals who are in good general health adopting a regular, graded and adaptive mode, winter swimming seems to confer cardiovascular (CV), and other health benefits. On the other hand, unaccustomed individuals are at risk of death either from the initial neurogenic cold-shock response, or from progressive decrease of swimming efficiency or from hypothermia. Furthermore, as it may occur with any intense exercise, individuals with evident or occult underlying CV conditions may be more susceptible to adverse effects with provocation of arrhythmias and CV events that may pose a significant health risk. Hence, a stepwise strategy to initiate and build up this recreational activity is recommended to enhance and sustain acclimation, achieve protection from potential risks of cold-water exposure and possibly avail from its promising health benefits. We need more data from prospective studies to better investigate the short- and long-term health consequences of this important recreational activity.

Published: November 2019

Introduction: Patients diagnosed with heart failure in primary care have a better prognosis than those diagnosed in hospital. However, most cases are missed in the community. Recent attention has focussed on the potential of early detection through screening. Natriuretic peptides (NPs) are tested by GPs and used to rule out heart failure in patients presenting with symptoms. Evidence is now emerging that they may also have a role in screening but their accuracy in this context and the associated optimal thresholds, have not been established. The impact that NP screening would have on patients and health care systems also remains unclear.

Methods: We aim to undertake a systematic search of the following sources: Ovid Medline, Embase, Cochrane Database of Systematic Reviews and Cochrane Central Register of Controlled Trials. Screening, data extraction and critical appraisal will be carried out independently and in duplicate by two reviewers. We will include studies based in the community with >100 participants that recruited a screened population. We will not add a study design filter and there will be no language restriction. The primary outcome will be the sensitivity and the specificity of NP screening and optimal thresholds for screening will be explored. Outcomes of interest for the impact analysis will include mortality, hospital admissions and cost effectiveness. This protocol has been developed in accordance with guidelines from the preferred reporting items for systematic review and meta-analysis protocols (PRISMA-P).

Discussion: This systematic review will identify how accurately NP screen for heart failure in the community and explore where NP screening thresholds should be set. It also aims to summarise the clinical impact of this strategy. Together, these results should inform future interventions that may provide an alternative pathway to facilitate improved detection of heart failure in the community.

Published: November 2019

Objectives

The optimal protocol for antibiotic loading in the articulating cement spacers for the treatment of prosthetic joint infection (PJI) remains controversial. The objective of the present study was to investigate the effectiveness of articulating cement spacers loaded with a new combination of antibiotics.

Methods

A retrospective cohort study involving 114 PJI cases treated with implantation of an articulating cement spacer between 2005 and 2016 was performed. The treatment outcomes of the conventional protocol (i.e. gentamicin and vancomycin (GV protocol)) were compared with those reported using the sophisticated antibiotic-loading protocol (i.e. vancomycin, meropenem, and amphotericin (VMA protocol)).

Results

There were 62 and 52 PJI cases treated with the GV and VMA protocols, respectively. Antimicrobial susceptibility testing revealed that 22/78 of all isolates (28.2%) in this series were resistant to gentamicin, whereas there were no vancomycin-, meropenem-, or amphotericin-resistant strains. The overall infection recurrence rates were 17.7% (11/62) and 1.9% (1/52), respectively (p = 0.006). In patients with a negative preoperative culture, there was no infection recurrence reported in the VMA cohort (0/45 (0%) vs 10/54 (18.5%) in the GV cohort; p = 0.002). Multivariate analysis indicated that the VMA protocol correlated with a decreased risk of infection recurrence compared with the GV protocol (p = 0.025).

Conclusion

The sophisticated VMA protocol for the loading of antibiotics in articulating cement spacers, as part of a two-stage exchange, was associated with a reduced rate of infection recurrence. This proposed protocol appears to be safe and effective, especially in patients with negative culture results prior to the first-stage operation.

Authors: Stuart Charlotte M , Zotova Elina , Koster Grielof , Varatharaj Aravinthan , Richardson Grace , Cornick Faye R , Weal Mark , Newman Tracey A , Postle Anthony D , Galea Ian
Published: November 2019

Background

Systemic inflammation is a marker of ill health and has prognostic implications in multiple health settings. Urinary neopterin is an excellent candidate as a nonspecific marker of systemic inflammation. Expression as urinary neopterin-to-creatinine ratio (UNCR) normalizes for urinary hydration status. Major attractions include (a) urine vs blood sampling, (b) integration of inflammation over a longer period compared with serum sampling, and (c) high stability of neopterin and creatinine.

Methods

A high-throughput ultraperformance LC-MS method was developed to measure neopterin and creatinine together from the same urine sample. The assay was applied in several clinical scenarios: healthy controls, symptomatic infections, and multiple sclerosis. Area under the curve was compared between weekly and monthly sampling scenarios. Analysis of a single pooled sample was compared with averaging results from analysis of individual samples.

Results

The assay has excellent intraassay and interassay precision, linearity of dilution, and spike and recovery. Higher UNCR was demonstrated in female vs male individuals, older age, inflammatory disease (multiple sclerosis), and symptomatic infections. In healthy controls, fluctuations in inflammatory state also occurred in the absence of symptomatic infection or other inflammatory triggers. Analysis of a single pooled sample, made up from weekly urine samples, integrates inflammatory activity over time.

Conclusions

UNCR is a useful biomarker of systemic inflammation. The method presented offers simplicity, speed, robustness, reproducibility, efficiency, and proven utility in clinical scenarios. UNCR fluctuations underline the importance of longitudinal monitoring, vs a single time point, to capture a more representative estimate of an individual's inflammatory state over time.
An overview of colistin resistance, mobilized colistin resistance genes dissemination, global responses, and the alternatives to colistin: A review
Authors: Gharaibeh Mohammad H. , Shatnawi Shoroq Q.
Published: November 2019

Colistin, also known as polymyxin E, is an antimicrobial agent that is effective against a variety of Gram-negative bacilli, especially the Enterobacteriaceae family. Recently, the wide dissemination of colistin-resistance has brought strong attention to the scientific society because of its importance as the last resort for the treatment of carbapenem-resistant Enterobacteriaceae infections and its possible horizontal transmission. The mobilized colistin resistance (mcr) gene was identified as the gene responsible for unique colistin resistance. Indeed, despite many studies that have revealed a pan variation in the existence of this gene, not only for the mcr genes main group but also for its many subgroups, the problem is growing and worsening day after day. In this regard, this review paper is set to review the updated data that has been published up to the end of 2019 third quarter, especially when related to colistin resistance by the mcr genes. It will include the present status of colistin resistance worldwide, the mcr gene dissemination in different sectors, the discovery of the mcr variants, and the global plan to deal with the threat of antimicrobial resistance. In line with global awareness, and to stop antibiotic misuse and overuse, especially in agricultural animals, the study will further discuss in detail the latest alternatives to colistin use in animals, which may contribute to the elimination of inappropriate antibiotic use and to the help in preventing infections. This review will advance our understanding of colistin resistance, while supporting the efforts toward better stewardship, for the proper usage of antimicrobial drugs in humans, animals, and in the environment.

Published: November 2019

Objective:Systemic lupus erythematosus is an autoimmune disease that affects multiple organs. It is well known that lupus patients have higher risk of osteoporosis, but if the disease affects mandibular cortical bone and alveolar bone is not fully established. The objective of this study was to evaluate periodontal disease defects and mandibular osteoporotic alterations in patients with lupus as compared to healthy patients using panoramic radiographs.Material and Methods:The panoramic radiographs of 72 patients with lupus and 360 healthy patients were evaluated for the presence of bone loss secondary to periodontal disease, classified as horizontal and vertical bone loss. We also assessed mandibular osteoporotic alterations by using the mandibular cortical index. Logistic regression analysis was applied to estimate the risk of mandibular osteoporotic alterations as well as horizontal and vertical bone loss in patients with lupus as compared to healthy patients.Results:There were no statistically significant differences between groups in the presence of horizontal bone defects and mandibular cortical indexes. However, patients with lupus demonstrated that patients with lupus were 2.17 more likely to present vertical bone loss than healthy patients.Conclusions:Patients with lupus might have higher risk of vertical bone loss than healthy patients due to pathophysiology of their disease. Further larger prospective studies should be performed to confirm our findings.

Published: November 2019

Buscamos neste artigo desenvolver uma abordagem da paisagem pela qual seja possível compreender a materialidade das formas e as subjetividades de quem as interpretam como componentes da disputa dos agentes produtores do espaço urbano nas as cidades. Entendendo as paisagens como maneiras de ver, a construção desta abordagem crítica se realiza a partir de sua articulação com categorias como valor de uso, valor de troca, bem como o conceito de estética da mercadoria. Com o suporte desde conjunto de conceitos, pensamos as paisagens da cultura dominante como aquelas produzidas tendo a realização do valor de troca como finalidade, a partir da produção de paisagens como uma estética de mercadorias urbanas condizentes com os referentes ideológicos da cultura dominante; e paisagens da cultura popular, onde a perspectiva dos usos como a moradia e o trabalho se sobrepõem a busca pela obtenção do valor de troca. A partir da construção desta abordagem, discutimos um conflito que envolve a participação de moradores e moradoras, representantes do Estado e de agentes imobiliários no Recife.

A concepção da função social da terra surge da ideia de que esta é um bem comum da humanidade, indispensável à existência de todas as formas de vida e o abrigo para a manutenção de todos os povos e suas culturas. O seu cumprimento está condicionado a produtividade da terra, aproveitamento adequado e racional dos recursos naturais, observância da legislação trabalhista e preservação do meio ambiente, simultaneamente. O presente artigo pretende discutir os preceitos da função social da terra, seu histórico e sua importância bem como a incapacidade de o latifúndio cumprir todos os seus pilares estabelecidos legalmente, pensar acerca de tais questões é imprescindível em tempos de investidas da classe latifundiária contra a reforma agrária e demarcação de terras bem como na desestruturação da legislação trabalhista e ambiental. A metodologia empregada consistiu em revisão bibliográfica sobre a temática que permitiu concluir que o latifúndio é inábil no cumprimento da função social da terra.

SIMULASI PELIMPAHAN BEBAN PMT OUTGOING PWI 06 SAAT TERJADI OVERLOAD SHEDDING PADA TRAFO INCOMING 03 GARDU INDUK PURWODADI DENGAN MONITORING VT SCADA BERBASIS ARDUINO MEGA 2560
Authors: Rizkifadhla Reza , Winarno Heru
Published: November 2019

Reza Rizkifadhla, Heru Winarno, in this article explains that overload shedding in incoming transformer occurs due to an increase in load current that exceeds the capacity of the transformer. If overload shedding is not handled, it will cause damage to the transformer, and even cause incoming trip feeders and a very wide blackout effect. Relay overload shedding mounted on incoming feeders works to anticipate overload shedding by deliberately releasing outgoing feeders gradually to reduce the load. This study aims to provide a simulation of the conditions of incoming feeders during normal times, during overload shedding and handling of outgoing feeders deliberately released by carrying out load maneuvers to other feeders with different incoming transformers. Maneuvers are carried out to maintain the reliability of the continuity of electricity distribution. In this study one simulation tool was designed. The design of this tool uses a relay and Arduino Mega 2560 as a control center. Arduino Mega 2560 reads the current using the ZMCT 103C sensor. The simulation is based on the overload shedding event that has occurred in Purwodadi Substation. As for controlling switching equipment and monitoring current and voltage is done using HMI with VT Scada software. In the experiment, 3 incoming normal currents were 2.2 A with a load of 5 12 VAC 5W lamps. Simulated maneuvering error, the load on incoming 3 increased to 2.60 A. This situation is considered to have reached the condition of overload shedding, relay PMT C trip to reduce the load. Incoming 3 returns back to normal, namely 1.68 A. Loads on PMT C that are extinguished are maneuvered to PMT E or PMT F which have different incoming.
EDD Online: What is new in its latest version 3.0
Authors: Markus Manfred
Published: November 2019

The recent publication ofEDD Onlineversion 3.0 (March 2019), based on Joseph Wright’sEnglish Dialect Dictionary(1898-1905), raises the question of what this last version, again provided by an Innsbruck project team, has added or changed in comparison to the previous ones. This paper describes the main improvements, focusing on five points: (1) the integration of theSupplement, (2) the implementation of a new kwic concordance, (3) the elaboration of the sorting modes applicable on the result lists after queries, (4) the new possibilities of quantifying retrievals, and (5) the elaboration of the last-result mode allowing more parameters and filters to be compatible with each other. The last chapter sketchily refers to further assets of the new version. The paper illustrates all its points by practical examples and screen shots. In doing so, it also provides an introduction to the sophisticated search tools now available in our interface and to the enormous dialectological and lexicographic potential of the digitised version of the most comprehensive English dialect dictionary ever published.

Cellulose triacetate from different sources: modification assessment through thermal and chemical characterization
Authors: Malucelli Lucca C. , Lomonaco Diego , Filho Marco A.S.C. , Magalhães Washington L.E.
Published: November 2019

Modification techniques have been widely employed to improve cellulose properties, thus increasing the diversity of industrial applications. While wood pulp cellulose is the most common source for industrial production, little has been studied about the effects of the cellulose source and its purity on modification. Therefore, this article investigates the influence of cellulose source (e.g. wood or cotton) on its modification (acetylation), by estimating the obtained degree of substitution (DS) through Fourier-transform infrared (FT-IR), proton nuclear magnetic resonance (1H NMR) and back titration. The intense reduction in samples’ crystallinity after acetylation was a result of breakage of inter- and intra-molecular hydrogen bonds, thus confirming acetylation. Although Avicel showed the highest cellulose content and was virtually free of hemicellulose and lignin, this did not affect the acetylation degree, as all samples were successfully triacetylated. The techniques used in this study were ideal for detecting acetylation and estimating the DS, which makes them good tools for modification studies of cellulose derivatives.
An electro-tunable Fabry–Perot interferometer based on dual mirror-on-mirror nanoplasmonic metamaterials
Authors: Sikdar Debabrata , Kornyshev Alexei A.
Published: November 2019

Mirror-on-mirror nanoplasmonic metamaterials, formed on the basis of voltage-controlled reversible self-assembly of sub-wavelength-sized metallic nanoparticles (NPs) on thin metallic film electrodes, are promising candidates for novel electro-tunable optical devices. Here, we present a new design of electro-tunable Fabry–Perot interferometers (FPIs) in which two parallel mirrors – each composed of a monolayer of NPs self-assembled on a thin metallic electrode – form an optical cavity, which is filled with an aqueous solution. The reflectivity of the cavity mirrors can be electrically adjusted, simultaneously or separately, via a small variation of the electrode potentials, which would alter the inter-NP separation in the monolayers. To investigate optical transmittance from the proposed FPI device, we develop a nine-layer-stack theoretical model, based on our effective medium theory and multi-layer Fresnel reflection scheme, which produces excellent match when verified against full-wave simulations. We show that strong plasmonic coupling among silver NPs forming a monolayer on a thin silver-film substrate makes reflectivity of each cavity mirror highly sensitive to the inter-NP separation. Such a design allows the continuous tuning of the multiple narrow and intense transmission peaks emerging from an FPI cavity via electro-tuning the inter-NP separation in situ – reaping the benefits from both inexpensive bottom-up fabrication and energy-efficient tuning.
Dissecting skewness under affine jump-diffusions
Authors: Zhen Fang , Zhang Jin E.
Published: November 2019

This paper derives the theoretical skewness in a five-factor affine jump-diffusion model with stochastic variance and jump intensity, and jumps in prices and variances. Numerical analysis shows that all of the uncertainties in this model affect skewness. The information regarding jumps in prices is mainly reflected in the short-term skewness. The skewness for other maturities carries the information that is highly correlated with variance. Furthermore, the theoretical VIX and skewness under a simplified five-factor model are used to fit the market risk-neutral volatility and skewness sequentially. The fitting performances are better than traditional double-jump models.
Benjamin Dahlke: New Directions for Catholic Theology. Bernard Lonergan’s Move beyond Neo-Scholasticism
Authors: Dahlke Benjamin
Published: November 2019

Wie andere aufgeschlossene Fachvertreter seiner Generation hat der kanadische Jesuit Bernard Lonergan (1904–1984) dazu beigetragen, die katholische Theologie umfassend zu erneuern. Angesichts der offenkundigen Grenzen der Neuscholastik, die sich im Laufe des 19. Jahrhunderts als das Modell durchgesetzt hatte, suchte er schon früh nach einer Alternative. Bei aller Skepsis gegenüber dem herrschenden Thomismus schätzte er Thomas von Aquin in hohem Maß. Das betraf insbesondere dessen Bemühen, die damals aktuellen wissenschaftlichen und methodischen Erkenntnisse einzubeziehen. Lonergan wollte dies ebenso tun. Es ging ihm darum, der katholischen Theologie eine neue Richtung zu geben, also von der Neuscholastik abzurücken. Denn diese berücksichtigte weder das erkennende Subjekt noch das zu erkennende Objekt hinreichend.
Sn-Doped Hematite for Photoelectrochemical Water Splitting: The Effect of Sn Concentration
Authors: Zhang Siyuan , Hajiyani Hamidreza , Hufnagel Alexander G. , Kampmann Jonathan , Breitbach Benjamin , Bein Thomas , Fattakhova-Rohlfing Dina , Pentcheva Rossitza , Scheu Christina
Published: November 2019

Hematite-based photoanodes have been intensively studied for photoelectrochemical water oxidation. The n-type dopant Sn has been shown to benefit the activity of hematite anodes. We demonstrate in this study that Sn-doped hematite thin films grown by atomic layer deposition can achieve uniform doping across the film thickness up to at least 32 mol%, far exceeding the equilibrium solubility limit of less than 1 mol%. On the other hand, with the introduction of Sn doping, the hematite crystallite size decreases and many twin boundaries form in the film, which may contribute to the low photocurrent observed in these films. Density functional theory calculations with a Hubbard U term show that Sn doping has multiple effects on the hematite properties. With increasing Sn4+ content, the Fe2+ concentration increases, leading to a reduction of the band gap and finally to a metallic state.

Authors: Hennecke Raphael
Published: November 2019

This article deals with a case study from competition policy and decartelization in West Germany in the early to mid 1950 s. Whereas much research has focused on the discussions about the German cartel law of 1958 and its long process of formation, this article takes a closer look at the possibilities that Ludwig Erhard and his Ministry of Economics already had under the Allied Laws of 1947 that remained in place until 1957. This is demonstrated by a case study about the soap cartel of 1954/55. While Erhard and most of his civil servants were aware that this cartel would not be able to solve the soap industry’s problems, they still decided to push the Allied authorities towards approving it to demonstrate the inadequacy of cartelization. Thereby, they dealt a blow to those leaders of industry associations arguing against a strict ban on cartels. One of Erhard’s most influential opponents, Fritz Berg, had praised the soap cartel, which allowed more internal competition than simple price fixing cartels, as a model for future cartels and an example proving the disadvantages of a flat-out cartel ban. By letting the cartel fail under the conditions of a rapidly modernizing market instead of banning it, Erhard dealt a major blow to Berg’s argument. This way, Berg and his allies could not blame the failure of the soap industry on decartelization.
CONFIGURAÇÕES DO HOMOEROTISMO NAS REVISTAS O MALHO E RIO NU
Authors: Farias Ronaldo Soares
Published: November 2019

O presente artigo pretende discutir, de forma comparatística, as charges Fresca Theoria (Requerimento) e Escabroso, publicadas na revista O Malho em 1903 e 1904, respectivamente, e o conto O menino do Gouveia, de Capadócio Maluco, publicado em 1914, em fascículos, na revista Rio Nu. As charges e textos, de cunho homoerótico, sugerem um público leitor homossexual, embora as revistas fossem destinadas, a priori, ao público heterossexual. O objetivo deste estudo é analisar como as configurações homoeróticas surgem nas revistas e como elas abordam a sexualidade masculina em um período em que a sociedade burguesa reprimia as publicações pornográficas relacionadas à homossexualidade. Como referencial teórico, serão utilizadas as seguintes obras: Além do carnaval: homossexualidade masculina no Brasil do século XX, de James Green (2000); Devassos no paraíso: a homossexualidade no Brasil da colônia à atualidade, de João Silvério Trevisan (2018); História da Sexualidade I: vontade saber, de Michel Foucault (1988), entre outras.Palavras-chave: Revistas; O Malho; Rio Nu; sexualidade; homoerotismo.
O ESTATUTO DO TEXTO E DO AUTOR TEATRAL NOS TRABALHOS DE COMPANHIAS CARIOCAS CONTEMPORÂNEAS
Authors: Barcelos Carolina Montebelo
Published: November 2019

O presente artigo tem por objetivo examinar o estatuto do texto e do autor teatral no teatro contemporâneo carioca. A análise privilegia trabalhos de duas companhias teatrais, os Fodidos Privilegiados e os Atores de Laura, embora outras companhias também sejam abordadas de maneira mais abrangente na conclusão. Procura-se, inicialmente, o entendimento dos diversos conceitos de teatro contemporâneo e do papel do texto e do autor teatral nesse contexto. Para fins argumentativos, são levadas em consideração as transformações ocorridas em relação à escrita e ao uso do texto teatral a partir dos teatros de grupo no Brasil das décadas de 60 e 70, outras mudanças com o teatro de encenador na década de 80 e as novas formas de abordagem do texto e o trabalho do dramaturgo no teatro contemporâneo. Palavras-chave: Texto dramatúrgico; texto não-dramatúrgico; autor teatral; teatro contemporâneo; companhias cariocas.
A INVENÇÃO DA HETERONORMATIVIDADE: UM ROMANCE AUTOBIOGRÁFICO
Authors: Zanelatto Santos Rosana Cristina
Published: November 2019

A naturalização da heterossexualidade via heteronormatividade alimenta uma lógica de desumanização do sujeito, por meio de um processo que se inicia pelo corpo, estendendo-se pela linguagem e pelas relações de gênero, sociais, políticas e culturais, o que torna nua a identidade desse sujeito. Ele passa então a ser (re)conhecido por sua existência física/material e não por aquilo que ele quer ser e por aquilo que ele quer que o mundo compreenda nele/dele. Propõe-se a possibilidade de compreensão da heteronormatividade como uma invenção retórica que contribui significativamente para a encenação e a fixação de uma aparência de naturalização, de centralidade e de necessidade acerca das diferenças de gênero, tendo como reforço ações como a transfobia e a homofobia. Para dialogar com essa possibilidade, elegeu-se o romance autobiográfico de João W. Nery (2011) Viagem solitária: memórias de um transexual trinta anos depois.Palavras-chave:  Heteronormatividade; invenção; retórica; literatura brasileira contemporânea.
MENSAGENS CIFRADAS: PARANOIA EM "2666" DE ROBERTO BOLAÑO
Authors: Silveira Xerxenesky Antônio Carlos
Published: November 2019

Este artigo discute a maneira como a imaginação paranoide – uma marca recorrente da literatura contemporânea, na opinião de críticos como Stefano Ercolino – se manifesta nas duas primeiras seções do romance 2666, do autor chileno Roberto Bolaño. Traçando breves paralelos com a produção de Philip K. Dick e Thomas Pynchon, discute-se o que os romances e contos de Bolaño oferece de singular, e de que modo esta simboliza um caminho para a produção literária que gira em torno de conceitos como fragmentação e a arte do excesso.Palavras-chave: Literatura latino-americana; paranoia; literatura comparada; fragmentação; excesso.
UMA ALMA ASSINALADA: TESSITURAS ENTRE FICÇÃO E HISTÓRIA EM AS CARTAS DO DOMADOR, DE TABAJARA RUAS
Authors: Rizzon Carlos Garcia
Published: November 2019

As tessituras entre ficção e história de As cartas do domador, obra de Tabajara Ruas, configuram um movimento em que conflitos históricos do sul do Brasil aparecem imbricados a una tradicional lenda pampiana. Os aportes de lendas podem ser considerados elementos significativos para o estudo do passado porque permitem o acesso a um universo da oralidade que expressa um conhecimento popular e inclui saberes de sujeitos analfabetos, tradicionalmente excluídos na escrita da história. Nesse sentido, através da lenda do “Negrinho do pastoreio”, é possível recuperar acontecimentos que descrevem o contexto histórico e social no sul do Brasil para denunciar atrocidades no tratamento dado aos escravos. Essa lenda apresenta, portanto, um componente político que desconstrói o mito da existência de uma democracia no campo nas estâncias do pampa. Junto à questão da opressão vivida pelos escravos, As cartas do domador inclui o ambiente pré-revolucionário dos “farroupilhas” y ainda o sonho de liberdade dos negros fugidos que vivem em acampamentos quilombolas. Esses são traços históricos que irão desfazer cenas sobrenaturais da lenda, revelando que as crueldades sofridas pelo negrinho estão construídas na história de muitos jovens escravos. Dessa forma, o coronel Netto de As cartas do domador não é a figura documentada na história, porém empresta ao romance o contexto que ambienta os feitos narrados. Por outro lado, o negrinho do romance não é unicamente a invenção que se mantém no imaginário gauchesco, mas sim é também a representação de uma realidade existente no passado.Palavras-chave: Lenda; História; Literatura.
INTERMIDIALIDADE COMO PROCESSO DE RESSIGNIFICAÇÃO NARRATIVA EM DIE BRÜCKE
Authors: Munsberg Gabriel Felipe Pautz
Published: November 2019

Com o final da Segunda Guerra Mundial, as artes alemãs libertaram-se da censura e posicionaram-se contrárias à guerra, como é o exemplo do romance Die Brücke (A ponte, 1958), de Manfred Gregor, e sua adaptação fílmica homônima, de Bernhard Wicki (1959). O presente trabalho pretende elencar, ainda que de forma sucinta, as articulações entre (e intra-)mídias – a saber: intertextualidade, transposição, referência e combinação de mídias – realizadas pelo cinema, através de linguagem própria. Para tal análise, o embasamento teórico apropriado remete-se às teorias de intermidialidade (Rajewsky, 2012), sem esquecer da intertextualidade (Samoyault, 2008).Palavras-chave: Cinema; intermidialidade; literatura.

Bridging the Gap: Bringing Professionals into the Classroom to Effectively Teach Environmental Science Concepts
Authors: Ware Mallory , Sampson Christie , Lann Delaney , Linard Erica , Chance Lauren Garcia
Published: November 2019

Hands-on learning is a highly effective teaching method for topics in STEM disciplines. Unfortunately, environmental science teachers sometimes lack the tools to engage their students in hands-on experimentation in real-world research outside of the classroom. Partnerships between science professionals and teachers can help address this disparity, and operating within an established community science program is an excellent way for teachers and professionals to provide K–12 students opportunities for involvement in real-world research. We developed a four-stage program that maximizes the benefits of bringing together members of the professional and academic sectors; the stages include Learn, Collect, Report, and Communicate (LCRC). The goal of this program is to bring science professionals into a K–12 classroom to emphasize the importance of conducting research using the scientific method, to promote responsible community science, improve students' data literacy and critical thinking skills, and highlight the relevance of science communication. We demonstrate this program with a case study using water quality research in high school AP classes. Evaluations of the case study indicate this framework, and the engagement with science professionals alters students' perceptions of science and scientists while giving them the skills, knowledge, and confidence to pursue scientific endeavors.
Exploring Genetic Drift via Manual Simulations
Authors: Pecor Keith W.
Published: November 2019

Genetic drift is an important mechanism in microevolution, but it can be more challenging to understand than other mechanisms (e.g., natural selection). This group project allows students to simulate random changes in allelic frequencies over generational time using a few simple supplies and was well received when included in an introductory biology course at the collegiate level.
