Ciências sociais em saúde: perspectivas e desafios para a saúde coletiva
Authors: Ribeiro Patricia Tavares , Castro Leonardo
Published: July 2020

RESUMO Desde a institucionalização da saúde coletiva, dos movimentos pela redemocratização e pela Reforma Sanitária até os dias atuais, transformações importantes ocorreram na sociedade brasileira e no mundo. Nas últimas décadas, as ciências sociais vêm buscando acompanhar essas transformações e desenvolver a reflexão sobre seus impactos. No campo da saúde coletiva brasileira, as chamadas ‘ciências sociais e humanas em saúde’ refletem essa dinâmica, introduzindo novos objetos de estudo e abordagens, assimilando também inovações oriundas da teoria social. O presente ensaio propõe uma releitura da trajetória das ‘ciências sociais em saúde’ no Brasil e as mudanças verificadas em sua produção desde os estudos pioneiros do campo até os dias atuais, no bojo do processo da institucionalização da saúde coletiva como área de conhecimento especializada. Busca-se identificar desafios e perspectivas para o desenvolvimento da subárea considerando as transformações que afetam a problemática sanitária nas sociedades contemporâneas. Reconhecendo a contribuição das ciências sociais em saúde para a compreensão dos processos saúde-doença e das políticas de saúde, argumenta-se que as transformações sociais recentes requerem um investimento intelectual renovado, capaz de contemplar as novas dinâmicas sócio-políticas e a produção social dos riscos, bem como trazer aportes mais adequados à formulação de respostas governamentais no setor saúde.

Published: July 2020

RESUMO Dando continuidade a iniciativas para tornar a Comissão de Ciências Sociais e Humanas em Saúde da Associação Brasileira de Saúde Coletiva (Abrasco) mais inclusiva e plural, como o ciclo de simpósios na gestão 2014-2016, a experiência de gestão nessa Comissão no período de 2017-2019 é apresentada com o objetivo de destacar suas prioridades, conquistas e desafios. Uma análise documental de planos diretores e registros de atividades promovidas pela Comissão em eventos científicos foi conduzida, resultando na divisão do texto em três partes: uma análise comparativa de seu Plano Diretor atual; uma lista das atividades promovidas pela Comissão em eventos científicos; uma discussão sobre a avaliação da produção científica. A renovação dos representantes de instituições que integram a Comissão resultou no aumento do número de integrantes, bem como da diversidade regional, tornando-a a única das comissões da Abrasco com representação institucional em todas as regiões do País. Essa expansão se deu em meio a um contexto singular na política científica nacional, já que os critérios de avaliação da produção científica vigentes, predominantemente quantitativos, estavam sendo contestados.

Objective: to identify the association between moral distress and the supporting elements of moral deliberation in Brazilian nurses. Method: a cross-sectional study conducted with Brazilian nurses working in health services at different complexity levels. The research protocol consisted of the Brazilian Scale of Moral Distress in Nurses, a sociodemographic and labor questionnaire, and a list of bases and ethical elements used for moral deliberation. For analysis, descriptive statistics, chi-square test, and Poisson regression were used. Results: 1,226 nurses took part in the study. The 12 elements associated with the moral deliberation process were classified as important for nurses’ actions, especially the professional experience acquired, code of ethics/law of professional practice, and ethical and bioethical principles. The relationship of moral distress showed higher prevalence in the Beliefs, culture and values of the patient, Beliefs and personal values, and Intuition and Subjectivity elements. Conclusion: the results showed a balance between the subjective criteria of professional experience and the objective ones of deontology for moral deliberation.
Retrocesso da reforma psiquiátrica: o desmonte da política nacional de saúde mental brasileira de 2016 a 2019
Authors: Cruz Nelson Falcão de Oliveira , Gonçalves Renata Weber , Delgado Pedro Gabriel Godinho
Published: July 2020

Resumo O artigo analisa os retrocessos na Política Nacional de Saúde Mental no período de 2016-2019, com base em estudo das normativas emanadas pelo governo federal e documentos de caráter público, e no estudo dos dados do Ministério da Saúde relativos à rede de saúde mental do Sistema Único de Saúde. Foram avaliados todos os documentos normativos que compõem um conjunto de ‘reorientações’ da Política, além daqueles que a afetam diretamente, incluindo posicionamentos contrários emitidos por instâncias dos poderes executivo, legislativo e judiciário. A análise indica os primeiros efeitos destas mudanças na Rede de Atenção Psicossocial, como o incentivo à internação psiquiátrica e ao financiamento de comunidades terapêuticas, ações fundamentadas em uma abordagem proibicionista das questões relacionadas ao uso de álcool e outras drogas. A análise dos dados de gestão permite afirmar que há tendência de estagnação do ritmo de implantação de serviços de base comunitária. Este estudo pretende contribuir para uma melhor compreensão sobre os fundamentos e a direção estratégica das mudanças, que implicam retrocesso nas diretrizes da Reforma Psiquiátrica, pretendendo ampliar o debate sobre as formas de resistência ao desmonte da Política Nacional de Saúde Mental.
A ética do silêncio racial no contexto urbano: políticas públicas e desigualdade social no Recife, 1900-1940
Authors: FISCHER BRODWYN MICHELLE
Published: July 2020

RESUMO Mais de meio século após o preconceito racial ter se tornado o principal alvo dos movimentos urbanos pelos direitos civis nos Estados Unidos e na África do Sul, e décadas depois do surgimento dos movimentos negros contemporâneos no Brasil, o conjunto de ferramentas legislativas criado no Brasil para promover o direito à cidade ainda adere à longa tradição brasileira de silêncio acerca da questão racial. Este artigo propõe iniciar uma exploração das raízes históricas desse fenômeno, remontando ao surgimento do silêncio sobre a questão racial na política urbana do Recife, Brasil, durante a primeira metade do século XX. O Recife foi e é um exemplo paradigmático do processo pelo qual uma cidade amplamente marcada por traços negros e africanos chegou a ser definida política e legalmente como um espaço pobre, subdesenvolvido e racialmente neutro, onde as desigualdades sociais originaram na exclusão capitalista, e não na escravidão e nas ideologias do racismo científico. Neste sentido, Recife lança luzes sobre a política urbana que se gerou sob a sombra do silêncio racial.

Published: July 2020

Abstract Indroduction: Establishing which parameters to use for diagnosing malnutrition in hemodialysis patients is a challenge in clinical practice. The handgrip strength (HGS) has stood out as a method of assessing nutritional status. Thus, the aim of this study was to determine the cut-off point for HGS in the assessment of the risk of malnutrition and inflammation in HD patients, and its association with other parameters. Methods: Study carried out in hemodialysis units in the city of Curitiba, Brazil. We obtained the cut-off point of the HGS through the ROC curve, using the malnutrition and inflammation score (MIS) as a reference. We checked the relationship (Odds ratio) between the variables “MIS” and “HGS” with the other study variables using the multivariate analysis (logistic regression). Results: We assessed 238 patients (132 men), between 18 and 87 years of age (median = 59). The HGS cut-off point for diagnosing malnutrition and inflammation according to the reference used was <14.5 kg for women, and <23.5 kg for men. According to the HGS criteria, malnourished patients were older (OR = 0.958), with lower arm circumference (OR = 1.328) and higher scores in the malnutrition and inflammation score (OR = 0.85). Conclusion: HGS was significantly correlated with other nutritional assessment parameters. These results suggest that HGS is a valid screening tool to identify the risk of malnutrition and inflammation in hemodialysis patients.

Abstract The consumer market has been demanding quality plant products, without any contamination or chemical residues, restricting their use in postharvest. As a result, is necessary increase the development of research seeking more sustainable and economic alternatives. The objective was to identify the ideal concentration of eucalyptus essential oil to maintain postharvest quality of ‘Carola’ roses. At laboratory, stems of the ‘Carola’ roses were standardized at 35 cm, labeled and subjected to the following doses of eucalyptus (Eucalyptus globulus) essential oil: 0.25%; 0.5%; 0.75%; 1.0% and 1.25%. Spraying with distilled water was used as a control. The experiment was conducted in a completely randomized design, in a factorial scheme consisting of two factors: six postharvest treatments and seven evaluation dates (0, 1, 2, 3, 4, 5, 6 and 7 days). Four replications were used, with two flowers each. Stems fresh mass and color of the petals were analyzed daily. In addition, the visual quality was also evaluated. The total anthocyanin content in the petals was evaluated every three days at the beginning, middle and end of the experimental period. Eucalyptus essential oil in all doses tested provided better maintenance on the postharvest quality of roses: 0.25% and 0.5% (better grades), 1.0% and 1.25% (lower hue angle) and 0.25% (higher anthocyanin content). On the 5th day, the flower stems lost 16% of fresh mass, without signs of wilting and the assigned scores also indicated that the stems remained fit for commercialization until the fifth day (total vase life). In conclusion, eucalyptus essential oil at doses 0.25%, 0.50%, 1.0% and 1.25% is effective in maintaining the quality of ‘Carola’ roses for up to five days at 25 °C.
Experimental evaluation of the thermal and hygrometric behavior of a Colombian greenhouse used for the production of roses (Rosa spp.)
Authors: Villagran Edwin , Bojacá Carlos
Published: July 2020

Abstract The spatial behavior of the environmental variables involved in rose production is one of the factors of greatest current interest in the Colombian ornamental sector. The aim of this work consisted in the evaluation of a passive greenhouse through an experimental approach that included the capture and recording of data through a grid of 40 sensors homogeneously distributed inside the greenhouse. The data processing was carried out through the application of geostatistical techniques that allowed to obtain contour plots for 5 levels of radiation intensity. The results of the exploratory analysis showed that the behavior of temperature, relative humidity and vapour pressure deficit are not the most suitable for rose production, mainly for the conditions of the night period where the temperature exhibited values below 12.5 °C, the relative humidity was above 90% and the vapour pressure deficit was below 0.1 kPa. On the other hand in the structural analysis the circular model of theoretical semivariogram was the one that better degree of adjustment presented in comparison with the experimental data finding that a strong spatial dependency exists for the studied variables, the prediction of the not sampled points was made by means of the method of ordinary kriging finding that horizontal gradients of temperature and relative humidity exist inside the greenhouse that increases in magnitude according to the level of radiation arriving to reach values of 6.1 °C and 30.4%.
Analysis of the microclimatic behavior of a greenhouse used to produce carnation (Dianthus caryophyllus L.)
Authors: Villagran Edwin , Bojacá Carlos
Published: July 2020

Abstract Carnation production in Colombia, the world’s main exporter, takes place entirely in naturally ventilated greenhouses. This type of structure presents non-homogeneous microclimate conditions which differentially affect crop growth and development, which is why this issue has been of great research interest in recent years. The objective was to determine the microclimatic behavior of a passive spatial-type greenhouse used in Colombia for carnation production. The experimental approach included the collection of meteorological data in the external environment through a weather station and in the inside of the greenhouse through a grid of 40 sensors uniformly distributed in a horizontal plane. Data processing to determine the spatial variability of temperature, relative humidity and vapour pressure deficit (VPD) is done by using geostatistical techniques and predicting these variables at unsampled points through the ordinary Kriging method. The main results obtained allowed us to determine that the conditions generated inside the greenhouse are not the optimal ones recommended for carnation production and that, in addition, the behavior of the variables studied shows a heterogeneous distribution, obtaining spatial variations in the horizontal profile evaluated for the night period of 0.5 °C, 9.1% and 1.5 kPa and for the daytime period of 7.2 °C, 42.6% and 1.5 kPa for temperature, humidity and VPD respectively.

Published: July 2020

Research background. TomloxB is the main isoform of lipoxygenase associated with ripening and senescence of fruits. On the other hand, ethylene, a gaseous hormone, is essential for the regulation of ripening in climacteric fruits like tomatoes. However, the relationship between TomloxB and ethylene production has not been thoroughly studied. Therefore, we aim to assess the effect of exogenous ethylene in transgenic tomatoes that contain a silenced TomloxB gene, and subsequently evaluate lipoxygenase activity, 1-aminocyclopropane-1-carboxylic acid oxidase and ethylene production; as well as to quantify the expression of the genes encoding 1-aminocyclopropane-1-carboxylic acid oxidase and TomloxB. Experimental approach. To investigate the effect of lipoxygenase and 1-aminocyclopropane-1-carboxylic acid oxidase activity, fruits harvested at the stages of break, turning and pink were used. Tomatoes at break stage collected from transgenic and wild type plants were used to determine ethylene production and gene expression. Genetically modified and wild type tomato fruits were exposed to 100 μL/L exogenous ethylene. Lipoxygenase activity was measured spectrophotometrically. Activity of 1-aminocyclopropane-1-carboxylic acid oxidase and ethylene production were determined by gas chromatography. Oligonucleotides for differentially expressed genes: 1-aminocyclopropane-1-carboxylic acid oxidase and TomloxB were used to determine gene expression by real-time PCR. Results and conclusions. The data showed that silencing of TomloxB caused a reduction in lipoxygenase activity and ethylene production in tomato fruits, and also reduced 1-aminocyclopropane-1-carboxylic acid oxidase activity. Hence, the addition of exogenous ethylene increased lipoxygenase activity in all treatments and 1-aminocyclopropane-1-carboxylic acid oxidase activity only in transgenic lines at break stage, consequently there was a positive regulation between TomloxB and ethylene, as increasing the amount of ethylene increased the activity of lipoxygenase. The results suggest that lipoxygenase may be a regulator of 1-aminocyclopropane-1-carboxylic acid oxidase and production of ethylene at break stage. Novelty and scientific contribution. These results lead to a better understanding of the metabolic contribution of TomloxB in fruit ripening and how it is linked to the senescence-related process, which can lead to a longer shelf life of fruits. Understanding this relationship between lipoxygenase and ethylene can be useful for better post-harvest handling of tomatoes.

Published: July 2020

OBJECTIVE: To describe the prevalence of nursing diagnostics and to analyse differences between the groups according to the indicator created from the diagnoses and intervention of the CIPE® relating to job satisfaction. METHOD: 869 workers attending the occupational health assessments of an oil industry with nurse practitioners, using a data collection form to support clinical reasoning in the definition of diagnostics and intervention, with CIPE®. Data collected were grouped into five indicators: food aspects, interpersonal relationships, physical health, health behaviours and working conditions. RESULTS: 13 types of diagnoses and 18 interventions were mapped, being the most prevalent "job satisfaction" (85.0 %) and "promoting healthy relationship and communication techniques" (76.3 %), respectively. The student's t-test was used to compare scores of the five indicators between the groups. The "satisfied at work" revealed better interpersonal relationships (p < 0.001). The group intervened with the initiative "to promote healthy relationships and communication techniques and to encourage healthy relationships" demonstrates better interpersonal relationships (p < 0.01) and better physical health (p < 0.05). The best working conditions (p < 0.01) were identified in the group subject to "other interventions". CONCLUSION: Structured performance of the nurse practitioner in the worker healthcare enables the development of strategies aimed at implementing improvements within organizational aspects of the nursing work.

MARVICS: A Robust and Safe Magnetic Nanoparticle based RNA Extraction Method Compatible with Phenol-chloroform Inactivated Infectious Samples v2
Authors: Li Mo , Ramos-Mandujano Gerardo
Published: July 2020

Diagnosis and surveillance of emerging pathogens such as SARS-CoV-2 depend on nucleic acid isolation from clinical and environmental samples. Under normal circumstances, samples would be processed using commercial proprietary reagents in Biosafety 2 (BSL-2) or higher facilities. A pandemic at the scale of COVID-19 has caused a global shortage of proprietary reagents and BSL-2 laboratories to safely perform testing. Therefore, alternative solutions are urgently needed to address these challenges. We developed an open-source method called Magneticnanoparticle-Aided Viral RNA Isolation of Contagious Samples (MAVRICS) that is built upon reagents that are either readily available or can be synthesized in any molecular biology laboratory with basic equipment. Unlike conventional methods, MAVRICS works directly in samples inactivated in acid guanidinium thiocyanate-phenol-chloroform (e.g., TRIzol), thus allowing infectious samples to be handled safely without biocontainment facilities.

Published: July 2020

A method is proposed for estimating the range of mineral group content in the cores of silicate bottom sediments of lakes based on the search for the minimum and maximum content of stoichiometric minals that make up the group of minerals, provided that the balance of the mineral composition and the content of elements in the sample is observed. The mineral components were determined using the method of qualitative X-ray phase analysis, the contents of the main rock-forming elements were determined by X-ray fluorescence analysis. Comparison with the results of quantitative X-ray phase analysis showed that the contents of mineral groups either lie in the range calculated in the extreme search procedure based on data on the element composition, or overlap with the calculated range within the measurement error. The systematic discrepancy between the results of calculating the range of content of the silicon dioxide phase and the results of quantitative X-ray phase determination of quartz observed for the samples under consideration is due to the presence of an X-ray amorphous phase of biogenic silica. The proposed method for estimating the range of mineral group content is easy to implement, uses the publicly available MS Excel software, and can be useful for estimating variations in mineral composition by core depth, in conditions of frequent shortages of individual sample material distributed between different methods of analysis

Published: July 2020

Debido a la caída abrupta a nivel mundial del costo nivelado de las tecnologías renovables no convencionales para la generación de energía con estas fuentes (en el caso de los mercados en Estados Unidos entre 39 y 152 USD/MWh para la energía solar fotovoltaica y entre 26 y 50 USD/MWh para la eólica), se ha sustituido la utilización de mecanismos como las Feed in Tariff por las subastas, como un mecanismo de mercado viable para incentivar la inversión en estas fuentes de generación. Por medio del modelo de difusión tecnológica de Bass, este artículo analiza el impacto que tienen los incentivos actuales, contemplados en la Ley 1715 de 2014, en la inversión en energía solar fotovoltaica en Colombia. Los principales resultados arrojados por el escenario de un proyecto a gran escala muestran una capacidad instalada de energía solar fotovoltaica de 1.542 MW en 2030, lo que lo hace el más rentable y el de mayor potencial de crecimiento. El aporte del artículo es examinar el potencial que tiene el mercado eléctrico colombiano respecto a la inclusión de energía solar fotovoltaica.

Published: July 2020

El objetivo de esta revisión sistemática ha sido analizar la influencia de la posesión del balón en el rendimiento físico de los equipos y los jugadores en el fútbol masculino de elite. Se realizó una búsqueda sistemática de artículos relevantes en inglés en una base de datos (Web of Science Core Collection) y un motor de búsqueda (PubMed) siguendo el protocolo de PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses). Las palabras clave “association football” y “soccer” se relacionaron con los términos: “possession of the ball”, “possession” “physical activity” y “physical performance”. Se buscaron estudios empíricos relacionados con el rendimiento físico y la posesión del balón para su inclusión y análisis. Se revisó el texto completo de 21 estudios. Globalmente, tener un alto (51–66%) o bajo (34–50%) porcentaje de posesión del balón produce diferencias muy poco relevantes en las distancias recorridas por los jugadores. Tan sólo la distancia cubierta con y sin la posesión del balón es significativamente diferente. Además, no está claro que correr más o menos pueda asociarse con un incremento de las probabilidades de ganar o perder.

A cryptographic hash work is a phenomenal class of hash work that has certain properties which make it fitting for use in cryptography. It is a numerical figuring that maps information of emotional size to a bit string of a settled size (a hash) and is expected to be a confined limit, that is, a limit which is infeasible to adjust. Hash Functions are significant instrument in information security over the web. The hash functions that are utilized in different security related applications are called cryptographic hash functions. This property is additionally valuable in numerous different applications, for example, production of digital signature and arbitrary number age and so on. The vast majority of the hash functions depend on Merkle-Damgard development, for example, MD-2, MD-4, MD-5, SHA-1, SHA-2, SHA-3 and so on, which are not hundred percent safe from assaults. The paper talks about a portion of the secure hash function, that are conceivable on this development, and accordingly on these hash functions additionally face same attacks.

Published: July 2020

Software-defined networking is the talk of the town in today’s networking industry. Because of the limitations of traditional networking, SDN is getting more popular every year. Lots of researches are taking place to improve the efficiency and overcome the challenges of SDN though it has many advantages. Hence one key problem of SDN is the network update. If the route update does not perform well, it causes congestion and inconsistencies in the network system whereas bandwidth utilization and security is our main concern. We have compared two pre-built algorithms especially for routing path update and proposed a new algorithm with maximum security and loop-free network.
HEX: Hyperbolic Event eXtractor, a Seismic Phase Associator for Highly Active Seismic Regions
Authors: Woollam Jack , Rietbrock Andreas , Leitloff Jens , Hinz Stefan
Published: July 2020

The task of seismic phase association is to correlate the onsets of radiated seismic energy with an underlying source. Commonly applied within seismic monitoring networks for event detection, it forms a vital component of many seismic processing pipelines. With the complexity of this task naturally increasing with the number of phases to simultaneously correlate, rapid advancements in the number of sensors per seismic deployment, along with improved picking algorithms have greatly increased the volume of phases now recorded across seismic networks. Although traditional phase association methods work well for historic catalogs, they become unreliable when tasked with associating the frequent smaller events recorded in the latest seismic datasets. Accurately correlating such events is crucial if seismologists are to better understand the underlying physical processes. The phase association problem is, therefore, being revisited with novel techniques now being applied to improve performance. We present a new technique for associating seismic phases, Hyperbolic Event eXtractor (HEX). HEX adapts the logic of Random Sample Consensus, a model estimation approach widely used in the computer vision community and specifically designed to deal with high proportions of noise in the data distribution. We demonstrate the performance of HEX in associating phases over a synthetic dataset for a regional seismic network in northern Chile. Synthetic testing reveals that HEX can correlate seismic phases when events have up to a ∼15  s average spacing.
Using Aftershocks to Help Locate Historical Earthquakes
Authors: Ebel John E.
Published: July 2020

For historical earthquakes, the spatial distributions of macroseismic intensity reports are commonly used to estimate the event locations. The methods to locate historical earthquakes assume that the highest seismic intensity shows the best estimate of the location of the earthquake. Uncertainties in the locations estimated from macroseismic data can be due to an uneven geographic distribution of sites with intensity reports, variations in intensities due to local soil conditions, ambiguous historical reports, and earthquake directivity effects. Additional constraint on the location of a historical earthquake can come from places where most aftershocks were felt, because these localities may have been closest to the fault on which the mainshock took place. Examples of estimated earthquake locations based on aftershocks are those of the 1727 MLg 5.6 earthquake in northeastern Massachusetts, the MLg 5.7 earthquake in Maine, and the 1755 MLg 6.2 earthquake offshore of Cape Ann, Massachusetts. In all of these cases, the earthquake locations based on the aftershock data are somewhat different from previous locations derived from the macroseismic intensities alone. Uncertainties with this method include identifying aftershocks in historical accounts and the possibility that smaller events that are reported following a strong earthquake are not on or near the mainshock rupture. Even so, evidence of possible aftershock activity may help constrain the location of that mainshock. Because aftershocks of strong earthquakes (M≥7) can last months to years, archival research for aftershocks must be carried out with a somewhat different mindset than that for a mainshock.
Widespread Small-Scale Anisotropic Structure in the Lowermost Mantle beneath the North American Continent and Northeastern Pacific
Authors: Lei Wei , Wen Lianxing
Published: July 2020

We constrain D″ anisotropy beneath the North American continent and northeastern Pacific using two approaches: (1) joint splitting analysis of SKS and SKKS phase pair for a common event, in which we obtain 158 pairs exhibiting discrepant splitting results and 791 pairs nondiscrepant splitting results; and (2) group splitting analysis of SKS (or SKKS) phase from neighboring events recorded at a common station, in which we observe 109 2°×2° grids with consistent splitting parameters, and 164 grids with abrupt changes from splitting to no splitting within 30–100 km. The seismic data from both analyses indicate that small-scale variations of D″ anisotropy are widespread beneath the studied regions, with a lateral scale up to tens of kilometers. For portion of the data recorded at the stations of simple upper-mantle anisotropy, we correct for the effects of upper-mantle anisotropy and obtain the splitting parameters of D″ anisotropy. The inferred D″ anisotropy exhibits a changing geographic pattern and lateral transition of anisotropy to a lateral scale of tens of kilometers. Such a length scale of changing anisotropy is also confirmed by synthetics modeling of the seismic data. We suggest that the inferred small-scale anisotropies could be best explained by the shape preferred orientation of widespread small-scale partial melt pockets derived by a composition change produced early in the Earth’s history, a similar compositional origin that was invoked to explain the African anomaly in the lower mantle.

The number of earthquakes in the western Canada sedimentary basin (WCSB) has increased drastically in the last decade related to unconventional energy production. The majority of reported earthquakes are correlated spatially and temporally with hydraulic fracturing (HF) well stimulation. In this study, we use waveform data from a new deployment of 15 broadband seismic stations in a spatial area of roughly 60×70km2, covering parts of the Montney Formation, to study the relationship between earthquakes and HF operations in the Dawson-Septimus area, British Columbia, Canada, where the two largest HF-related earthquakes in WCSB to date, an Mw 4.6 on 17 August 2015 and an ML 4.5 on 30 November 2018, have occurred. We use an automated short-term average/long-term average algorithm and the SeisComP3-software to detect and locate 5757 local earthquakes between 1 July 2017 and 30 April 2019. Using two clustering techniques and double-difference relocations of the initial catalog, we define event families that are spatially associated with specific wells, and exhibit temporal migration along a horizontal well bore and/or multiple fractures close to wells. Relocated clusters align in two dominant orientations: one roughly perpendicular to the maximum horizontal regional stress direction (SH) and several conjugate structures at low angles to SH. Comparing the two predominant seismicity lineations to regional earthquake focal mechanisms suggests that deformation occurs via thrust faulting with fault strike oriented perpendicular to SH and via strike-slip faulting with strike azimuth at low angles to SH. Local scale seismicity patterns exhibit clustering around individual HF wells, whereas regional scale patterns form lineations consistent with deformation on faults optimally oriented in the regional stress field.

Market and Accounting Risk Factors of Asset Pricing in the Classical and Downside Approaches
Authors: Rutkowska-Ziarko Anna , Markowski Lesław
Published: July 2020

Theoretical background: The variability of the company’s profitability is the result of the accompanying risk. To compare the profitability of many companies, relative profitability measures, which include profitability ratios, are more convenient. This article analyses market and accounting risk factors of CAPM. Risk was considered in variance and downside framework. Market betas, accounting betas were used in an extended version of the asset pricing model. Additionally, the influence of profitability ratios, such as ROA and ROE on the average rate of return on the capital market are considered.

Purpose of the article: The main purpose of this study is to test the standard and extended CAPM relations between systematic risk measures and mean returns for single companies quoted on the Polish capital market and equally-weighted portfolios in two approaches: variance and downside risk.

Research methods: The research based on individual securities and portfolios, compares the one-factor risk-return relationships with two-factor ones estimated using mean returns in cross-sectional regressions. The regressors were expressed in absolute terms and classical and downside beta coefficients. The sample includes companies differing in terms of size and across different industries.

Main findings: Portfolios with higher classical or downside market betas generate higher mean returns. The negative risk premium for accounting betas for variance and downside risk was identified. It is not in accordance with our earlier study of the Polish construction sector, where a positive and significant risk premium for downside accounting betas was found. The highest explanatory power of rates on returns on the Polish capital market were found for average ROA and ROE. This confirms the results of the previous studies on the Polish capital market for food and construction sectors.
Are Larger Banks More Efficient in the Central Eastern European Countries?
Authors: Kozak Sylwester
Published: July 2020

Theoretical background: The relationship between the size of banks and their efficiency has become an important subject for academics and policy makers in the recent decades. However, the outcomes of these studies are relatively divergent concerning the direction of this dependence.

Purpose of the article: The goal of this study is to assess how the size of banks affects their efficiency in the CEE countries in the years 2005–2017. Additionally, the relationship between the market concentration and banks efficiency is checked.

Research methods: The research covers 108 banks operating in eleven CEE countries. The efficiency scores are achieved through the SFA method and regressed with the individual bank characteristics and macroeconomic and sectoral variables.

Main findings: The results show that growing bank’s size and market share positively affect its efficiency. Additionally, higher concentration of the banking market has a similar effect. Higher inflation and GDP per capita decrease bank profit efficiency which can indicate that banks achieve the highest efficiency gains in less prosperous countries, however, in the low inflation environment. Additionally, banks’ efficiency is boosted with the growing development of the banking sector and increasing lending to the economy. Fast-growing banks tend to be more efficient, probably due to the positive effect of the fiancial leverage on profits.
