“Alô, cotovia!”: Manuel Bandeira na revista Anhembi
Authors: França George Luiz 
Published: May 2020

Como antologia do alto modernismo, a revista Anhembi (1950-1962), dirigida por Paulo Duarte, coligiu, ao longo de seus 144 números, significativo material que consiste em uma série de peças do processo de cristalização das forças da vanguarda modernista brasileira. Neste "rio de umas aves añumas", que é o Anhembi-Tietê bandeirante, várias são as cenas em que nos deparamos com Bandeira, seja como poeta historiografado por diferentes intérpretes do Modernismo, seja como autor de textos inéditos, em especial, o poema "Cotovia", peça exemplar de um procedimento de montagem que não apenas povoa a poética bandeiriana (em seus “desentranhados”), como é o paradigma da própria ideia de revista. Este texto pretende ler a presença de Bandeira em Anhembi, traçando as linhas da construção da imagem do poeta já maduro e apresentado, inclusive, como intérprete e dispositivo de interpretação do Modernismo e do moderno.

Published: May 2020

Abstract. The land surface and the atmospheric boundary layer are closely intertwined with respect to the exchange of water, trace gases, and energy. Nonlinear feedback and scale-dependent mechanisms are obvious by observations and theories. Modeling instead is often narrowed to single compartments of the terrestrial system or bound to traditional viewpoints of definite scientific disciplines. Coupled terrestrial hydrometeorological modeling systems attempt to overcome these limitations to achieve a better integration of the processes relevant for regional climate studies and local-area weather prediction. This study examines the ability of the hydrologically enhanced version of the Weather Research and Forecasting model (WRF-Hydro) to reproduce the regional water cycle by means of a two-way coupled approach and assesses the impact of hydrological coupling with respect to a traditional regional atmospheric model setting. It includes the observation-based calibration of the hydrological model component (offline WRF-Hydro) and a comparison of the classic WRF and the fully coupled WRF-Hydro models both with identically calibrated parameter settings for the land surface model (Noah-Multiparametrization; Noah-MP). The simulations are evaluated based on extensive observations at the Terrestrial Environmental Observatories (TERENO) Pre-Alpine Observatory for the Ammer (600 km2) and Rott (55 km2) river catchments in southern Germany, covering a 5-month period (June–October 2016).
The sensitivity of seven land surface parameters is tested using the Latin-Hypercube–One-factor-At-a-Time (LH-OAT) method, and six sensitive parameters are subsequently optimized for six different subcatchments, using the model-independent Parameter Estimation and Uncertainty Analysis software (PEST).
The calibration of the offline WRF-Hydro gives Nash–Sutcliffe efficiencies between 0.56 and 0.64 and volumetric efficiencies between 0.46 and 0.81 for the six subcatchments. The comparison of the classic WRF and fully coupled WRF-Hydro models, both using the calibrated parameters from the offline model, shows only tiny alterations for radiation and precipitation but considerable changes for moisture and heat fluxes. By comparison with TERENO Pre-Alpine Observatory measurements, the fully coupled model slightly outperforms the classic WRF model with respect to evapotranspiration, sensible and ground heat flux, the near-surface mixing ratio, temperature, and boundary layer profiles of air temperature. The subcatchment-based water budgets show uniformly directed variations for evapotranspiration, infiltration excess and percolation, whereas soil moisture and precipitation change randomly.

Published: May 2020

Postpartum depression (PPD) is associated with disturbances in many aspects of mother-infant interaction. We compared the content of the infant-directed speech (IDS), the expression of positive affection in the maternal voice and the attentional engagement in dyads of PPD and non-PPD mothers. Participants of this study were 80 mothers and their infants at 3-6 months. According to Edinburgh Postnatal Depression Scale (EPDS) 40 mothers were considered depressed. Mothers and their babies were videotaped during free play interactions. No significant differences were found among groups for the averages of all the categories. Two data sets representing optimal interactions styles were created based on the correlation coefficients. A linear regression analysis indicated that the mother`s years of education was a predictive factor for the occurrence of these interactive styles only for PPD mothers. PPD influenced mother-infant interaction when associated with maternal socio-demographic characteristics.

At the Canadian Testis Cancer Workshop, the rationale and feasibility of regionalization of testis cancer care were discussed. The two-day workshop involved urologists, medical and radiation oncologists, pathologists, radiologists, physician’s assistants, residents and fellows, and nurses, as well as patients and patient advocacy groups.
This review summarizes the discussion and recommendations of one of the central topics of the workshop — the centralization of testis cancer in Canada. It was acknowledged that non-guideline-concordant care in testis cancer occurs frequently, in the range of 18–30%. The National Health Service in the U.K. stipulates various testis cancer care modalities be delivered through supra-regional network. All cases are reviewed at a multidisciplinary team meeting and aspects of care can be delivered locally through the network. In Germany, no such network exists, but an insurance-supported online second opinion network was developed that currently achieves expert case review in over 30% of cases. There are clear benefits to regionalization in terms of survival, treatment morbidity, and cost. There was agreement at the workshop that a structured pathway for diagnosis and treatment of testis cancer patients is required.
Regionalization may be challenging in Canada because of geography; independent administration of healthcare by each province; physicians fearing loss of autonomy and revenue; patient unwillingness to travel long distances from home; and the inability of the larger centers to handle the ensuing increase in volume. We feel the first step is to identify the key performance indicators and quality metrics to track the quality of care received. After identifying these metrics, implementation of a “networks of excellence” model, similar to that seen in sarcoma care in Ontario, could be effective, coupled with increased use of health technology, such as virtual clinics and telemedicine.
Stakeholder perspectives and status of surgical simulation and skills training in urology residency programs in Canada
Authors: Lobo Anjali M. , Doucette Steve , Lantz-Powers Andrea G. 
Published: May 2020

Introduction: With the shift to competency-based training, surgical skills lab training (SSLT) may become a mandatory part of Canadian urology residency programs (CURPs). This study aims to identify: 1) the status of SSLT in CURP; 2) stakeholder perspectives on the utility of SSLT; 3) barriers to developing and implementing SSLT; and 4) how to address these barriers.
Methods: Surveys were developed and issued to three groups of stakeholders: 1) SSLT directors at all 13 CURPs (response rate 100%); 2) teaching faculty (response rate 33%); and 3) urology residents (response rate 24%). Surveys 2 and 3 were sent to ten English CURP. Results were collected through email and SurveyMonkey®.
Results: Nine of 13 CURPs have a dedicated SSLT; 46% of CURP have 1–3 sessions per year, 8% have 5–7, and 30% >7. Most residents have independent lab access, but 80% do so less than once monthly. Over 90% of stakeholders find SSLT useful, of which high-fidelity models are most preferred (faculty rated 3.66/4, residents 3.18/4). Program directors (PDs) identified lack of protected faculty time, funding, and infrastructure as the top three barriers to SSLT implementation. Residents found lack of faculty time, protected academic time, and infrastructure as barriers. PDs viewed protecting faculty time and more funding as potential solutions, while residents suggested protected faculty and academic time, and after-hours lab access.
Conclusions: Residents, faculty, and PDs in CURPs view SSLT as useful. Most CURPs have defined SSLT; programs without this have labs for resident use but are underused. To continue to develop and progress SSLT, more time, participation, and funding must be made available.

Introduction: Current literature on perioperative and oncological outcomes following radical cystectomy among different racial groups is limited, especially among Hispanics and Asians. The objective of this study was to assess the impact of racial differences on perioperative and oncological outcomes in a large cohort of bladder cancer patients who underwent radical cystectomy.
Methods: We retrospectively reviewed the records of 3293 patients who underwent radical cystectomy with curative intent at our institution between 1971 and 2017. Based on race, patients were categorized as Hispanic (n=190), Asian (n=145), African Americans (n=67), and Caucasian (n=2891). Baseline characteristics, pericystectomy complications, and oncological outcomes, including recurrence-free and overall survival, were compared between the racial groups.
Results: Mean patient age was 68±10.6 years. Median followup was 10.28 years. Body masss index and American Society of Anesthesiologists scores were significantly higher in Hispanic and African American population, and smoking incidence was lower in Asian patients. Hispanics presented with significantly higher clinical stage and longer time interval from diagnosis to treatment (mean 85.5 vs. 75.4 days in Caucasians, p<0.001). Overall 90-day complication and readmission rates were higher in Hispanics (41.06% and 18.95%, respectively). Oncological outcomes, however, were comparable between different race groups. In multivariate analysis, pathological nodal status and lymphovascular invasion were independent predictors of oncological outcomes, but race was not.
Conclusions: In this very large, ethnically diverse patient cohort who underwent radical cystectomy with curative intent, pericystectomy complications were more common in Hispanics; however, race was not an independent predictor of long-term oncological outcome.

Published: May 2020

Introduction: Adequate knowledge of biostatistics is essential for healthcare providers to stay up-to-date with medical advances and maintain an evidence-based practice. However, training in clinical research in Canadian residency programs varies considerably. Our study aimed to determine Canadian urology trainees’ knowledge of biostatistics and interpretation of the scientific literature.
Methods: We conducted a national survey of all Canadian urology residents and fellows, which assessed experiences with biostatistics, self-reported confidence with statistical questions, and knowledge of biostatistical concepts.
Results: Out of 201 urology trainees, 74 (36.8%) responded to the survey. The majority of respondents disagreed or strongly disagreed with the fact that they had sufficient training in biostatistics in medical school (67.6%) or that their current knowledge was sufficient for the rest of their career (66.1%). If given the chance, 82.3% of respondents would like to learn more about biostatistics. About half of respondents were able to correctly identify ordinal variables (51.5%), discrete variables (52.9%), or interpret adjusted odds ratios (50.0%). Despite senior residents reporting more confidence on biostatistical questions, our results did not demonstrate significant differences in overall knowledge according to level of training or experience with biostatistics.
Conclusions: Our results identified important knowledge gaps among current Canadian urology trainees. Most trainees do not believe they have sufficient training in biostatistics. Knowledge of basic statistical concepts was lower than expected and did not significantly differ according to level of training. Our results highlight the need for structured, dedicated training in biostatistics for urology trainees within the new Competence by Design teaching framework.

Exploring Science
Authors: Klahr David 
Published: May 2020

Einstein said that "the whole of science is nothing more than a refinement of everyday thinking." David Klahr suggests that we now know enough about cognition—and hence about everyday thinking—to advance our understanding of scientific thinking. In this book he sets out to describe the cognitive and developmental processes that have enabled scientists to make the discoveries that comprise the body of information we call "scientific knowledge."
Over the past decade Klahr and his colleagues have conducted extensive laboratory experiments in which they create discovery contexts, computer-based environments, to evoke the kind of thinking characteristic of scientific discovery in the "real world." In attempting to solve the problems posed by the discovery tasks, experiment participants (from preschoolers through university students, as well as laypersons) use many of the same higher-order cognitive processes used by practicing scientists. Through this work Klahr integrates two disparate approaches—the content-based approach and the process-based approach—to present a comprehensive model of the psychology of scientific discovery.

Intelligent Behavior in Animals and Robots
Authors: Mcfarland David , Bösser Tom 
Published: May 2020

This exciting study explores the novel insight, based on well-established ethological principles, that animals, humans, and autonomous robots can all be analyzed as multi-task autonomous control systems.
Intelligence takes many forms. This exciting study explores the novel insight, based on well-established ethological principles, that animals, humans, and autonomous robots can all be analyzed as multi-task autonomous control systems. Biological adaptive systems, the authors argue, can in fact provide a better understanding of intelligence and rationality than that provided by traditional AI.
In this technically sophisticated, clearly written investigation of robot-animal analogies, McFarland and Bösser show that a bee's accuracy in navigating on a cloudy day and a moth's simple but effective hearing mechanisms have as much to teach us about intelligent behavior as human models. In defining intelligent behavior, what matters is the behavioral outcome, not the nature of the mechanism by which the outcome is achieved. Similarly, in designing robots capable of intelligent behavior, what matters is the behavioral outcome.
McFarland and Bösser address the problem of how to assess the consequences of robot behavior in a way that is meaningful in terms of the robot's intended role, comparing animal and robot in relation to rational behavior, goal seeking, task accomplishment, learning, and other important theoretical issues.

Authors: Bassey Joseph Benedict , Odesola Isaac F. , Asobinonwu Dennis A. 
Published: May 2020

Aims: The performance of gas turbine is influenced by a number of factors which may be classified under three main headings: design limiting conditions, environmental dependent conditions and system respond condition. The design limiting conditions have been found to have influenced gas turbine performance most. In this study, two design limiting conditions (pressure ratio and maximum cycle temperature) were evaluated and estimated for optimal design and operations of gas turbine.
Study Design: Hierarchical order in selecting the two design condition parameters was proposed.
Methodology: Steady state energy and exergy concept was used to model the behavior of the plant.
Results: Result obtained indicated that at maximum cycle temperature of 1173K, 1273K, 1373K, 1473K, 1573K, and 1673K,maximum pressure ratio for optimal performance were 19, 24, 29, 36, 44 and 51 respectively.
Conclusion: These results provide insight into the performance behavior of gas turbine and also serve as a guide for operations and design optimization.
The Burden and Socio-demographic Differentials of Malaria Infection among Asymptomatic School Children in Gombe State, Nigeria
Authors: Danjin Mela , Adewoye Solomon O. , Sawyerr Henry O. 
Published: May 2020

Background: As a foremost disease of public health significance, malaria has wrecked untold havoc among children and pregnant women in developing countries with Africa and Nigeria being worst affected.
Objective: This study was aimed at documenting the prevalence and socio-demographic differences in the pattern of malaria infection among asymptomatic primary school children in Gombe state, Nigeria.
Methodology: Using a cross sectional study design 745 pupils aged 6 to 15 years were assessed from March to June 2019. The subjects were selected from 12 public and 6 private schools in 6 Local Government Areas (LGAs) of the state, using multi-stage sampling technique. Malaria rapid diagnostic test (mRDT) kits were deployed in screening the subjects for malaria parasites positivity or otherwise. Data was analyzed using IBM SPSS version 21 analytical software. And the findings were presented in tables and charts. Proportions were compared using chi square, with alpha significance level set at 0.05.
Results: The mean age of the participants was 9.96±2.26 and 379 (50.9%) of them were boys while the rest 366 (49.1%) were girls (about 1:1 male-female sex ratio). A total of 101 (13.6%) of the 745 school children screened yielded positive to malaria rapid diagnostic test (mRDT), with children from the public primary schools being significantly (p=0.000) more affected than their counterparts in the private schools (18.2% vs. 4.1%). Though male children were more affected by malaria, the difference was not statistically significant (15.0% vs. 12.0%, P=0.229). Similarly, significantly higher proportion (p=0.000) of pupils from the rural schools were affected and were about three times more at risk of malaria (OR=3.362, CI: 2.169-5.212) than their urban counterparts (22.4% vs. 7.9%). Low academic performance was found to be associated with malaria infection (p=0.012). Other socio-demographic factors associated with malaria infection among the pupils include; senatorial district, family size, source of parental care, tribe etc. However, from the evidence of this study there was no significant association between the prevalence of malaria infection and birth order, age group and gender of the school children.
Conclusion: In view of the high and disproportionate distribution of the burden of malaria among the subjects, it is hereby recommended that concerned authorities should include primary schools in the design and implementation of malaria control/ elimination programmes.
Highly Stable and Efficient Perovskite Solar Cells with 22.0% Efficiency Based on Inorganic–Organic Dopant‐Free Double Hole Transporting Layers

Published: May 2020

AbstractMost of the high performance in perovskite solar cells (PSCs) have only been achieved with two organic hole transporting materials: 2,2′,7,7′‐tetrakis(N,N‐di‐p‐methoxyphenylamine)‐9,9‐spirobifluorene (Spiro‐OMeTAD) and poly(triarylamine) (PTAA), but their high cost and low stability caused by the hygroscopic dopant greatly hinder the commercialization of PSCs. One effective alternative to address this problem is to utilize inexpensive inorganic hole transporting layer (i‐HTL), but obtaining high efficiency via i‐HTLs has remained a challenge. Herein, a well‐designed inorganic–organic double HTL is constructed by introducing an ultrathin polymer layer dithiophene‐benzene (DTB) between CuSCN and Au contact. This strategy not only enhances the hole extraction efficiency through the formation of cascaded energy levels, but also prevents the degradation of CuSCN caused by the reaction between CuSCN and Au electrode. Furthermore, the CuSCN layer also promotes the formation of a pinhole‐free and compact DTB over layer in the CuSCN/DTB structure. Consequently, the PSCs fabricated with this CuSCN/DTB layer achieves the power conversion efficiency of 22.0% (certified: 21.7%), which is among the top efficiencies for PSCs based on dopant‐free HTLs. Moreover, the fabricated PSCs exhibit high light stability under more than 1000 h of light illumination and excellent environmental stability at high temperature (85 °C) or high relative humidity (>60% RH).
