Authors: Roso Caetano Castro , Auler Décio , Delizoicov Demétrio
Published: May 2020

Encaminhamentos, principalmente educacionais, do movimento Ciência-Tecnologia-Sociedade (CTS) têm defendido a superação do modelo de decisões tecnocrático em temas sociais envolvendo Ciência-Tecnologia (CT). Contudo, ao incluir mais atores nos processos de tomada de decisões em temas envolvendo CT, em detrimento do modelo puramente tecnocrático, qual seria o papel dos técnicos? Para o enfrentamento dessa questão realizou-se uma articulação envolvendo a tríade: atuação de profissionais/especialistas, conhecimento técnico como um todo e processos formativos dos técnicos/tecnólogos. Neste trabalho, são realizadas considerações sobre a suposta neutralidade de CT, um dos pilares de modelos decisórios tecnocráticos, bem como são apresentadas e discutidas possíveis respostas obtidas para o problema de pesquisa, expressas em termos de papeis atribuídos aos técnicos em processos decisórios. Estes foram sintetizados em seis categorias: 1) Conhecimento Científico: condição necessária e suficiente, 2) Fornecer Informações Relevantes, 3) Fornecer Informações Relevantes e Avaliar Impactos de CT, 4) Reorientar a Agenda de Pesquisa em CT, 5) Viabilizar a Adequação Sociotécnica e 6) Buscar Soluções Junto com a Comunidade. Os principais aportes teóricos foram Paulo Freire e referenciais do movimento CTS com especial atenção ao Pensamento Latino-Americano em Ciência-Tecnologia-Sociedade (PLACTS).

“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.

Abstract. Secondary organic aerosol (SOA) is an important constituent of the
atmosphere where SOA particles are formed chiefly by the condensation or
reactive uptake of oxidation products of volatile organic compounds (VOCs).
The mass yield in SOA particle formation, as well as the chemical
composition and volatility of the particles, is determined by the identity
of the VOC precursor(s) and the oxidation conditions they experience. In
this study, we used an oxidation flow reactor to generate biogenic SOA from
the oxidation of Scots pine emissions. Mass yields, chemical composition
and volatility of the SOA particles were characterized and compared with SOA
particles formed from oxidation of α-pinene and from a mixture of
acyclic–monocyclic sesquiterpenes (farnesenes and bisabolenes), which are
significant components of the Scots pine emissions. SOA mass yields for
Scots pine emissions dominated by farnesenes were lower than for α-pinene but higher than for the artificial mixture of farnesenes and
bisabolenes. The reduction in the SOA yield in the farnesene- and
bisabolene-dominated mixtures is due to exocyclic C=C bond scission in
these acyclic–monocyclic sesquiterpenes during ozonolysis leading to smaller
and generally more volatile products. SOA particles from the oxidation of
Scots pine emissions had similar or lower volatility than SOA particles
formed from either a single precursor or a simple mixture of VOCs. Applying
physical stress to the Scots pine plants increased their monoterpene, especially monocyclic β-phellandrene, emissions, which further decreased SOA particle volatility and increased SOA mass yield. Our results
highlight the need to account for the chemical complexity and structure of
real-world biogenic VOC emissions and stress-induced changes to plant
emissions when modelling SOA production and properties in the atmosphere.
These results emphasize that a simple increase or decrease in relative
monoterpene and sesquiterpene emissions should not be used as an indicator of
SOA particle volatility.
Characteristics of sub-10 nm particle emissions from in-use commercial aircraft observed at Narita International Airport

Abstract. Civil aviation is undergoing rapid growth as a result of global economic development. Characterizing ultrafine particle emissions from jet aircraft equipped with turbofan engines, which are commonly used in civil aviation, is an important issue for the assessment of the impacts of aviation on climate and on human health. Previous studies have reported that particle number emissions from jet aircraft are dominated by volatile particles (mainly sulphate and organics) with mode diameters of 10–20 nm and that non-volatile particles (mainly soot) exhibit mode diameters of ~20–60 nm, depending on the engine types and thrust conditions. However, there are significant uncertainties in measuring particles with diameters smaller than ~10 nm, especially when fresh aircraft exhaust plumes are measured near the emission sources. We conducted field observations of aerosols and carbon dioxide (CO2) near a runway of Narita International Airport, Japan, in February 2018, with specific focuses on the contributions of sub-10 nm size ranges to total and non-volatile particles. Spiked increases in particle number concentrations and CO2 were observed to be associated with wind directions from the runway, which can be attributed to diluted aircraft exhaust plumes. We estimated the particle number emission indices (EIs) for discrete take-off plumes. The median total particle number EI with diameters larger than 2.5 nm was ~60 times greater than the median non-volatile particle number EI with diameters larger than 10 nm for take-off plumes. This value can be interpreted as the difference between total particle number emissions under real-world conditions and non-volatile particle number emissions regulated by standard engine tests. More than half of particle numbers in the plumes were found in the size range smaller than ~10 nm on average for both total and non-volatile particles. The mode diameters of the size distributions of particle number EIs were found to be smaller than ~10 nm in most cases, and the peak EI values were larger than those previously reported under real-world operating conditions. This study provides new insights into the significance of sub-10 nm particles in aircraft exhaust plumes under real-world conditions, which is important in understanding aviation impacts on human health and also in developing aviation emission inventories for regional and global models.
TROPOMI Aerosol Products: Evaluation and Observations of Synoptic Scale Carbonaceous Aerosol Plumes during 2018–2020

Published: May 2020

Abstract. TROPOMI near UV radiances are used as input to an inversion algorithm that simultaneously retrieves aerosol optical depth (AOD) and single scattering albedo (SSA) as well as the improved qualitative UV Aerosol Index (UVAI) that accurately accounts for the scattering effects of water clouds. We first present the TROPOMI aerosol algorithm (TropOMAER), an adaptation of the currently operational OMI near UV (OMAERUV & OMACA) inversion schemes, that take advantage of TROPOMI’s unprecedented fine near UV spatial resolution and the availability of ancillary aerosol-related information to derive aerosol loading in cloud-free and above-cloud aerosols scenes. An evaluation analysis of TROPOMI retrieved AOD/SSA products using sun-photometer observations shows improved levels of agreement with respect to those obtained with the heritage coarser resolution sensor. We then use TropOMAER aerosol retrieval results to discuss the the US Northwest and British Columbia 2018 wildfire season, the 2019 biomass burning season in the Amazon Basin, and the unprecedented January 2020 fire season in Australia that injected huge amounts of carbonaceous aerosols in the stratosphere.
Early Jurassic climate and atmospheric CO2 concentration in the Sichuan paleobasin, Southwest China
Authors: Li Xianghui , Wang Jingyu , Rasbury Troy , Zhou Min , Wei Zhen , Zhang Chaokai
Published: May 2020

Abstract. Unlike marine archives, terrestrial sediments show more complicated and dynamic environment and climate. This work presents new results of climate-sensitive sediment observation and carbon-oxygen isotope analyses of lacustrine and pedogenic carbonates for the Early Jurassic Ziliujing Formation from the grand Sichuan paleobasin (GSB), Southwest China. Lithofacies analysis indicates calcisols were widespread in riverine and flood plain facies. Climate–sensitive sediments and carbon-oxygen isotopes with palynofloral assemblages manifest that an overall (semi-) arid climate dominated the GSB; and that it became drier through time, accompanied by occasional evaporites in the Toarcian. This climate pattern is similar with the arid climate in Colorado Plateau, western America, but distinct from the relatively warm-humid climate in North China and northern Gondwanaland in Southern Hemisphere. The estimated Early Jurassic atmospheric CO2 concentration (pCO2) from carbon isotopes of pedogenic carbonates shows a range of 980–2610 ppmV (~ 3.5–10 times the pre-industrial value) with a mean 1660 ppmV. Three phases of pCO2 (the Sinemurian 1500–2000 pmV, the Pliensbachian 1000–1500 ppmV, and the early Toarcian 1094–2610 ppmV) and two events of rapid falling pCO2 by ~ 1000–1300 ppmV are observed, illustrating the pCO2 perturbation in the Early Jurassic. The pattern and associated rapid falling events of pCO2 are compatible with the excursions of stable isotopes and seawater temperature from the coeval marine sediments, consistent with a positive feedback of climate to pCO2 through the Early Jurassic.
A full Stokes subgrid scheme in two dimensions for simulation of grounding line migration in ice sheets using Elmer/ICE (v8.3)
Authors: Cheng Gong , Lötstedt Per , von Sydow Lina
Published: May 2020

Abstract. The flow of large ice sheets and glaciers can be simulated by solving the full Stokes equations using a finite element method.
The simulation is particularly sensitive to the discretization of the grounding line, which separates ice resting on bedrock and ice floating on water, and is moving with time.
The boundary conditions at the ice base are enforced by Nitsche's method and a subgrid treatment of the grounding line element.
Simulations with the method in two dimensions for an advancing and a retreating grounding line illustrate the performance of the method.
The computed grounding line position is compared to previously published data with a fine mesh, showing that similar accuracy is obtained using subgrid modeling with more than 20-times-coarser meshes.
This subgrid scheme is implemented in the two-dimensional version of the open-source code Elmer/ICE.
High-resolution fully coupled atmospheric–hydrological modeling: a cross-compartment regional water and energy cycle evaluation

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.

Abstract. Simulations from seven global coupled climate models performed at high and standard resolution as part of the High Resolution Model Intercomparison Project (HighResMIP) have been analyzed to study the impact of horizontal resolution in both ocean and atmosphere on deep ocean convection in the North Atlantic and to evaluate the robustness of the signal across models. The representation of convection varies strongly among models. Compared to observations from ARGO-floats, most models substantially overestimate deep water formation in the Labrador Sea. In the Greenland Sea, some models overestimate convection while others show too weak convection. In most models, higher ocean resolution leads to increased deep convection in the Labrador Sea and reduced convection in the Greenland Sea. Increasing the atmospheric resolution has only little effect on the deep convection, except in two models, which share the same atmospheric component and show reduced convection. Simulated convection in the Labrador Sea is largely governed by the release of heat from the ocean to the atmosphere. Higher resolution models show stronger surface heat fluxes than the standard resolution models in the convection areas, which promotes the stronger convection in the Labrador Sea. In the Greenland Sea, the connection between high resolution and ocean heat release to the atmosphere is less robust and there is more variation across models in the relation between surface heat fluxes and convection. Simulated freshwater fluxes have less impact than surface heat fluxes on convection in both the Greenland and Labrador Sea and this result is insensitive to model resolution. is not robust across models. The mean strength of the Labrador Sea convection is important for the mean Atlantic Meridional Overturning Circulation (AMOC) and in around half of the models the variability of Labrador Sea convection is a significant contributor to the variability of the AMOC.
On a new robust workflow for the statistical and spatial analysis of fracture data collected with scanlines (or the importance of stationarity)
Authors: Bistacchi Andrea , Mittempergher Silvia , Martinelli Mattia , Storti Fabrizio
Published: May 2020

Abstract. We present an innovative workflow for the statistical analysis of fracture data collected along scanlines, composed of two major stages, each one with alternative options. A prerequisite in our analysis is the assessment of stationarity of the dataset, that is motivated by statistical and geological motivations. Calculating statistics on non-stationary data can be statistically meaningless, and moreover the normalization and/or sub-setting approach that we discuss here can greatly improve our understanding of geological deformation processes. Our methodology is based on the analysis of the cumulative spacing function (CSF) and cumulative spacing derivative (CSD), that allows defining the boundaries of stationary domains in an objective way. Once stationarity has been analysed, other statistical methods already known in literature can be applied. Here we discuss in details methods aimed at understanding the degree of saturation of fracture systems based on the type of spacing distribution, and we evidence their limits in cases where they are not supported by a proper spatial statistics analysis.

Railroad transportation system is considered a viable model in several aspects; however, its implementation is dependent on several decision factors, which include regional production viabilities, specific locations for railroad station construction, land slope, among others. This work aims to indicate the optimal location for new railroad stations and the best interconnection path among them in order to expand the railroad network of the Paraná State (Brazil) to regions that are not contemplated by this type of transportation. The layers used as information plans contemplated the geographic location of the regions with the highest representativeness in the agroindustrial production, associated with the demands and transportation of production and topographic relief. Was defined 1,390.802 km of new railroads, mainly in the Western and Southern Center regions of Paraná. This implantation generates a very significant importance for the municipalities since it increases the demand of revenues and generation of new currencies.

Authors: Santos Ana Karina , Dos Santos Luiz Silva , Bussab Vera Silvia Raad
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.
Perioperative complications and oncological outcomes following radical cystectomy among different racial groups: A long-term, single-center study

Published: May 2020

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.
Knowledge and confidence level of Canadian urology residents toward biostatistics: A national survey
Authors: Couture Félix , Nguyen David-Dan , Bhojani Naeem , Lee Jason Y. , Richard Patrick O.
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.

This study aimed to identify organizational justice and its impact on organizational commitment in the General Administration of Customs in the State of Kuwait.      The study population consists of workers in the General Administration of Customs in the State of Kuwait, who are (5000) employees. An appropriate sample of 150 people was drawn to distribute the study questionnaire to them, and 111 questionnaires valid for analysis were retrieved.

It is found that there is statistically significant effect at the level of significance (α≤0.05) for organizational justice with its combined dimensions (Procedural Justice, Distributive Justice and Interactional Justice) on the organizational commitment in the General Administration of Customs in the State of Kuwait.

According to these results the researcher suggested: - The necessity of senior management commitment to the dimensions of organizational justice in order to raise the level of job commitment to the highest degree.- Because there is a relationship between justice and commitment and being direct, therefore, it can be strengthened by showing the interest of different departments in strengthening the values of justice by satisfying the needs and desires of workers and reducing obstacles and obstacles impeding the achievement of their goals.

De Unierechtelijke status van de Caribische Koninkrijksdelen

Het aflopen van het Verdrag van Cotonou in 2020, de aanstaande Brexit en het nog in te voeren LGO-Besluit 2021 kunnen het startpunt zijn voor een hernieuwde dialoog over de Unierechtelijke status van de Caribische Koninkrijksdelen. In deze bijdrage wordt aandacht besteed aan de complexe relatie van de Landen en Gebieden Overzee (LGO) met de Europese Unie en de gevolgen van een eventuele statuswijziging van de Nederlandse LGO in Ultraperifeer Gebied (UPG).

On 17 July 2017, the Act of 23 March 2017 amending the Act - Criminal Code, the Act on juvenile proceedings and the Act - Code of Criminal Procedure entered into force. The legislator's aim was to increase the level of protection of minors and the helpless due to physical or mental condition. The implementation of the indicated purpose took place by introducing changes to art. 53 § 2 of the Penal Code determining the circumstances affecting the sentence and by introduction of modifications in the scope of certain types of prohibited acts (Article: 156, 189, 207, 210, 211, 240 of the Penal Code). The article discusses issues related to the application of art. 240 of the Penal Code in the case of offenses committed to the detriment of minors. Then from article 240 of the Penal Code were selected and discussed prohibited acts, witch protecting minors under 15 years of age and those that protecting everyone against the most severe forms of physical and sexual violence. Further considerations focus on the analysis of issues related to the subject side of the crime, the assessment of the premises for promptness and reliable information, the circumstances abrogating criminal liability and doubts related to the application of art. 240 of the Penal Code by persons obliged to keep professional secrecy.
Research on Aeroelasticity Phenomenon in Aeronautical Engineering
Authors: Thi Kim Dung Hoang , Phu Khanh Nguyen
Published: May 2020

Aeroelasticity phenomena arise when structural deformations induce changes on aerodynamic forces due to airplane structures that are not completely rigid. The additional aerodynamic forces cause an increase in the structural deformations, which leads to greater aerodynamic forces in a feedback process. These interactions may become smaller until reaching a condition of equilibrium or may diverge catastrophically if resonance occurs. Flutter is an instability aeroelasticity phenomenon which is the most difficult to predict. In this chapter, a numerical method and an experimental method were realized to predict aeroelastic response and characteristic parameters of a wing structure. The numerical method was firstly developed based on the interaction between computational fluid dynamic and computational structural dynamic methods using a coupling system, fluid–solid interaction (FSI), in the ANSYS software. Then, an experiment was set up in suitable conditions to study aeroelasticity characteristics with the goal of comparing the numerical results with the experimental results on the same wing structure at low speed. After that, a developed code based on immersed boundary method (IBM) was realized to predict aeroelasticity response and characteristic parameters of the wing structure. AGARD 445.6 wing model was chosen for this developed procedure at high speed. Obtained results were compared to other numerical and experimental results.
Ransomware and Academic International Medicine
Authors: C. Miller Andrew , M. Khan Abbas , Ziad Sophia
Published: May 2020

Healthcare is among the leading industries targeted by cyber-criminals. Ransomware exploits vulnerabilities to hijack target information technology (IT) infrastructures for monetary gain. Due to the nature and value of information, access to medical information enables cyber-criminals to commit identity theft, medical fraud, and extortion, and illegally obtain controlled substances. The utility and versatility of medical information, extensive centralized storage of medical information, relatively weak IT security systems, and the expanding use of healthcare IT infrastructure all contribute to an increase in cyber-attacks on healthcare entities. Research suggests that an individual’s medical information is 20–50 times more valuable to cyber-criminals than personal financial information. As such, cyber-attacks targeting medical information are increasing 22% per year. This chapter explores the history of ransomware attacks in healthcare, ransomware types, ransom payment, healthcare vulnerabilities, implications for international health security, and means of institutional protection.
Brace Treatment for Adults with Spinal Deformities
Authors: Weiss Hans-Rudolf , Turnbull Deborah
Published: May 2020

The bracing indication for adults with spinal deformities is two-fold: (1) pain and (2) deformity. Although pain is more frequent in the adult population with scoliosis, there is no correlation between the angle of curvature and pain intensity. Pain is reportedly more frequent in patients who were operated. Non-specific pain can successfully be treated with stabilisation exercises; however, some patients may need brace treatment to improve their pain. Today, with the help of a simple clinical test, we can distinguish between different types of lower back pain allowing a differential approach to the symptom. There is some evidence that pain can successfully be reduced by these approaches mainly influencing the sagittal profile. In patients with bigger deformities and in patients aiming at reducing their deformity, pattern-specific scoliosis braces are a successful choice according to published research cases. The different specific brace types/designs along with the differential indication for these brace types will be described in this chapter.
Arte Ilegal: historia y perspectivas de la propiedad intelectual
Authors: Córcoles César , Xalabarder Raquel
Published: May 2020

Arte Ilegal se presenta dentro de Copyfight, un ‘acontecimiento cultural’ dedicado a cuestionar las formas de la explotación actual de los derechos de autor. Si de algo puede criticarse a Copyfight es de un cierto populismo. Tanto en julio del año pasado en el CCCB como la semana anterior a Arte Ilegal, en Copyfight, los presentadores habían atacado –con más o menos razón, no nos corresponde discutirlo– las actuaciones de los lobbies y los grupos de las diferentes industrias culturales.
ARTISTIC GAZE OF TWO PAPUAN CHOREOGRAPHERS: VISUAL PERSPECTIVES ROOTED IN THE ORAL TRADITIONS OF THE KAMORO AND ASMAT TRIBE
Authors: Ismar Madia Patra , Pratiwi Rahayu
Published: May 2020

This article is based on the artistic practice of two Papuan choreographers trained in the Jakarta Institute of the Arts Dance Study Program. Both based their choreographies on their traditional roots which were presented as site specific performances in their respective villages. The choice of visuals and dramatic bodily expressions created by them, though a new dance design, was based on their deeply ingrained roots as indigenous Papuans. The roots called upon to be re-interpreted as choreography were based on the oral traditions they grew up with as part of their identity. The focus in this article is on the work by Martinus Akai from the Asmat tribe performed in 2013, and the work by Alfo Smith from the Kamoro Tribe performed in 2018. The purpose of this study is to understand the way Papuan choreographers ingrained in their cultural heritage re-imagine the traditions passed down from ancient times through their ancestors. The research done by the choreographers was in the context of revisiting the rituals and ancestral narratives and interpreting for a contemporary expression. The research done for this paper was based on discussions had with both the choreographers during the process of creating their individual work. Among the methods for collecting data by the choreographers for creating their work was field research, observations, interviews and personal memories experiencing their cultural heritage. The observations by the writers for this article were during the creating process in the studio and on site and viewing the end results both as presentations and site specific performances.
