Modelling of diesel generator operating modes on the basis of the engine speed characteristic in autonomous photovoltaic systems
Authors: Karamov D.N. , Naumov I.V. , Ivanov D.A. , Podyachikh S.V.
Published: September 2020

The article presents a universal diesel generator model based on the processing of the engine speed characteristic. Processing uses linear interpolation with a fixed discrete step. An autonomous photovoltaic system arbitrarily located in Eastern Siberia is used as a case study. Solar radiation modelling was based on multi-year meteorological data sets using the tandem of Iqbal-Kasten/Czeplak models. The photovoltaic system under investigation consists of two 400 kW diesel generators (totalling 800 kW) and one 375 kW solar power plant. In calculating the operating modes, the diesel power plant’s minimum limit load factor was taken into consideration. The resulting values of the diesel generator’s operating modes show the following patterns. As an example, the lesser the diesel generator’s load, the lesser engine speed and the higher specific fuel consumption. The suggested model can be used in comprehensive energy research, specifically in areas such as optimal equipment configuration, operational reliability and sustainability as well as cost-efficiency.
Automated tools for the development of microservice compositions for hybrid scientific computations
Authors: Oparin G.A. , Bogdanova V.G. , Pashinin A.A.
Published: September 2020

In recent years, a significant amount of research is focused on the development of tools for creating composite web-services for solving both business and scientific complex problems. This study discusses tools for building compositions or ensembles of microservices (depending on the method of integration) developed based on the HPCSOMAS framework. These tools are oriented on the application in a package of applied microservices for solving computationally complex problems of structural analysis and parametric synthesis of controlled dynamic systems in a heterogeneous high-performance computing environment. In particular, binary dynamic systems are studied using the Boolean constraint method for both their qualitative analysis and synthesis of laws to control these systems. Creating and executing composite services is carried out on a semantic peer-to-peer network of agents. The HPCSOMAS framework supports two modes of these processes, both the static creation and application of a composite service based on the procedural formulation of the problem and dynamic, based on the declarative formulation. In the first case, agents deployed on the network perform hierarchical control over the execution of the composition of microservices, in the second case, decentralized asynchronous management of the ensemble of microservices. Both operating modes are automated, and the validity of the resulting composite service is checked based on a logical approach. The tools are aimed both at a professional programmer and the end-user, a specialist in the subject domain. The HPCSOMAS framework supports the execution of composite microservices in a hybrid computing infrastructure, which includes both cloud and on-premises resources.

Abundance and seasonal distribution of the Southern North Carolina estuarine system stock (USA) of common bottlenose dolphins (Tursiops truncatus)
Authors: Silva Daniela
Published: September 2020

ABSTRACT
 
Under the U.S. Marine Mammal Protection Act, bottlenose dolphins [Tursiops truncatus] along the United States Atlantic coast are managed as a series of 17 distinct stocks.  To determine the status of each stock, the Potential Biological Removal (PBR) is compared with anthropogenic removals, primarily as a result of fisheries bycatch.  Estimates of abundance, with associated measures of variance, are required to generate the PBR for each stock.  The objectives of the current study were to estimate abundance for the Southern North Carolina Estuarine System Stock (SNCESS) of bottlenose dolphins and to refine the southern boundary of this stock.  To meet these objectives, photo-identification surveys were conducted during the summer and winter of 2014 in estuarine and nearshore coastal waters in southern North Carolina.  The surveys extended 25km south of the defined southern stock boundary, along the northern South Carolina coast.  One mark and one recapture survey were conducted for each season.  Each survey was completed in four or five days and covered over 300km of survey tracklines.  Dorsal fin images were processed and managed using FinBase, and only images of suitable quality and distinctiveness were used for estimates of abundance.  A three-step decision tree was used to assign each dolphin group to either the SNCESS or an adjacent coastal stock, based on sighting location, ranging patterns derived from matches to photo-identification catalogs, and statistical modeling.  Only sightings classified as SNCESS were used to estimate stock abundance.  Abundance estimates were calculated using three methods:  the Chapman modification to the Lincoln-Petersen method, package Rcapture in Program R, and program MARK 6.2.  The most parsimonious estimate was generated using the package Rcapture for program R, with the bias corrected M0 model yielding an estimate of 283 dolphins (CV = 0.33, 95% CI 170-396) in the summer of 2014.  The distribution of SNCESS dolphins shifted south in the winter and several individuals were observed up to 70km southwest of the currently recognized southern boundary.  The results of this study support the current definition of the SNCESS but suggest revisions to the southern boundary.  The SNCESS is the smallest bottlenose dolphin stock off the east coast of the USA and is at risk of population decline as a result of fisheries-related mortality.

Authors: Moslemi Petrudi Amin , Cristian Scurtu Ionut
Published: September 2020

Optimization is to find the best answer among existing situations. Optimization is used in the design and maintenance of many engineering systems to minimize costs or maximize profits. Due to the widespread use of optimization in engineering, this topic has grown a lot. In this paper, the optimization of multi-objective of Water Hybrid Nanofluid/Carbon Nanotubes is investigated. Multi-Objective Particle Swarm Optimization (MOPSO) algorithm has been used in order to maximize thermal conductivity and minimum viscosity by changing the temperature (300 to 340 ºk) and the volume fraction (0.01 to 0.4%) of nanofluid. Artificial Neural Network (ANN) modeling of experimental data has been used to obtain the values. Parto fronts, the optimal points and different values are 20 members and 15 iterations, and in order to compare the results optimization process on the first, fifth, tenth fronts, a relation has been proposed to predict the viscosity and Parto fronts in the optimization process. The aim of the study was to optimize nanofluid to reduce viscosity and increase thermal conductivity.

Published: September 2020

This paper proposes new rheological models for olive oil. The purpose of this study was to find an exponential  dependence between temperature and dynamic viscosity of olive oil, using one equation. Equation constants lnη0, A1 and t1 were determined by fitting exponential. The olive oil have investigated using a Haake VT 550 Viscotester developing shear rates ranging between 3 and 120 s-1 and measuring viscosities from 104 to 106 mPa·s when the HV1 viscosity sensor is used.

Olive oil dynamic viscosity decreases with increasing temperature at constant shear rate.  Plotting the ln dynamic viscosity depending on temperature shows an exponential decline.

The COVID-19 pandemic has disrupted every area of our daily activities and businesses. After the health crisis, the food crisis is the next battle to encounter, which will need to mobilize all energies to maintain social security and protect the citizens of the world. For sustained support and recovery of rural and urban populations, especially in the dryland areas of Sub-Saharan Africa, seed of the well-adapted, nutrient dense varieties should flow. The solution of quality seed flow equation is complex and involves several intervention areas, e.g., adapted and modern groundnut, chickpea, pigeonpea, sorghum and finger millet varieties, sustainable and long term approaches leveraging various seed production and delivery models, remote information and knowledge dissemination systems, digital seed production and delivery roadmaps, digitized variety release and promotion processes, smart food campaigns and trainings to promote good utilization of nutrient dense crops.

In these days education has changed as an essential for everyone. There are many preschools, elementary, secondary, higher secondary schools, universities, arts and science colleges and many. Finding the best school or institution for their children is really very tough for parents in these days. Our work is to create a web application to create online survey, which contains questions and feedbacks about the schools and institutions. The survey questions are related to the attributes, and the behavior of educational institution on behalf of the quality of education, school environment, teaching methodologies, about the management and teachers. And we give authority to attend the survey for the peoples from various places i.e. the former students of various institutions and schools. Thus using our survey we are collecting the data about the schools and institutions, then the data will be handover to the analyst. And the analyst will process the data and make decisions about the institutions and schools. They will decide the ratings for the institutions and schools in Tamilnadu, India. Based on the ratings the parents and students can choose their schools and colleges.

Improving the Sectional MOSAIC Aerosol models of WRF-Chem with the revised Gridpoint Statistical Interpolation System and multi-wavelength aerosol optical measurements: DAO-K experiment 2019 at Kashi, near the Taklamakan Desert, northwestern China
Authors: Chang Wenyuan , Zhang Ying , Li Zhengqiang , Chen Jie , Li Kaitao
Published: September 2020

Abstract. The Gridpoint Statistical Interpolation data assimilation (DA) system was developed for the four-size bin sectional Model for Simulating Aerosol Interactions and Chemistry (MOSAIC) aerosol mechanism in the Weather Research and Forecasting-Chemistry (WRF-Chem) model. The forward and adjoint operators for the aerosol optical depth (AOD) analysis were derived from WRF-Chem aerosol optical code. We applied three-dimensional variational DA to assimilate the multi-wavelength AOD, ambient aerosol scattering coefficient, and aerosol absorption coefficient, measured by the sun-sky photometer, nephelometer, and aethalometer, respectively. These were undertaken during a dust observation field campaign at Kashi in northwestern China in April 2019. The results showed that the DA analyses decreased the low biases in the model aerosols; however, it had had some deficiencies. Assimilating the surface particle concentration increased the coarse particles in the dust episodes, but AOD, and the coefficients for aerosol scattering and absorption, were still lower than observed values. Assimilating aerosol scattering coefficient separately from AOD improved the two optical quantities. However, it caused an overestimation of the particle concentrations at the surface. Assimilating the aerosol absorption coefficient yielded the highest positive bias in the surface particle concentration, aerosol scattering coefficient, and AOD. The positive biases in the DA analysis were caused by the forward operator underestimating particle scattering and absorption efficiency. As a compensation, the DA system increased particle concentrations excessively so as to fit the observed optical values. The best overall improvements were obtained from the simultaneous assimilation of the surface particle concentration and AOD. The assimilation did not substantially change the aerosol chemical fractions. After DA, the clear-sky aerosol radiative forcing at Kashi was −10.5 W m−2 at the top of the atmosphere, which was 46 % higher than the background radiative forcing value.
Sources and processes sustaining surface CO2 and CH4 fluxes in a tropical reservoir: the importance of water column metabolism
Authors: Soued Cynthia , Prairie Yves T.
Published: September 2020

Abstract. Freshwaters are important emitters of carbon dioxide (CO2) and methane (CH4) to the atmosphere, two potent greenhouse gases (GHG). While aquatic surface GHG fluxes have been extensively measured, there is much less information about their underlying sources. In lakes and reservoirs, surface GHG can originate from horizontal riverine flow, the hypolimnion, littoral sediments, and water column metabolism. These processes are generally studied separately, leading to a fragmented assessment of their relative role in sustaining CO2 and CH4 surface fluxes. In this study, we quantified sources/sinks of CO2 and CH4 in the epilimnion along a hydrological continuum in a permanently stratified tropical reservoir (Borneo Island). Results showed that horizontal inputs are an important source of both CO2 and CH4 (18 to 100 % of surface emissions) in the upstream reservoir branches. However, this contribution fades along the hydrological continuum, becoming negligible in the main basin of the reservoir, where CO2 and CH4 are uncoupled and driven by different processes. In the main basin, vertical CO2 inputs and sediment CH4 inputs contributed to on average 60 and 23 % respectively to the surface fluxes of the corresponding gas. Water column metabolism exhibited wide amplitude and range for both gases, making it the most influential but uncertain component in the epilimnetic gas budgets. Overall our results show that while sources sustaining surface CO2 and CH4 fluxes vary spatially and between the two gases, internal water metabolism remains a dominant driver. However, this study also highlights challenges and knowledge gaps related to estimating ecosystem-scale CO2 and CH4 metabolism, which hinder aquatic GHG flux predictions.

Abstract. In the fall of 2017, an airborne field campaign was conducted from the NASA
Armstrong Flight Research Center in Palmdale, California, to advance the
remote sensing of aerosols and clouds with multi-angle polarimeters (MAP)
and lidars. The Aerosol Characterization from Polarimeter and Lidar (ACEPOL)
campaign was jointly sponsored by NASA and the Netherlands Institute for
Space Research (SRON). Six instruments were deployed on the ER-2 high-altitude aircraft. Four were MAPs: the Airborne Hyper Angular Rainbow
Polarimeter (AirHARP), the Airborne Multiangle SpectroPolarimetric Imager
(AirMSPI), the Airborne Spectrometer for Planetary EXploration (SPEX
airborne), and the Research Scanning Polarimeter (RSP). The remainder were
lidars, including the Cloud Physics Lidar (CPL) and the High Spectral
Resolution Lidar 2 (HSRL-2). The southern California base of ACEPOL enabled
observation of a wide variety of scene types, including urban, desert,
forest, coastal ocean, and agricultural areas, with clear, cloudy, polluted,
and pristine atmospheric conditions. Flights were performed in coordination
with satellite overpasses and ground-based observations, including the
Ground-based Multiangle SpectroPolarimetric Imager (GroundMSPI), sun
photometers, and a surface reflectance spectrometer. ACEPOL is a resource for remote sensing communities as they prepare for the
next generation of spaceborne MAP and lidar missions. Data are appropriate
for algorithm development and testing, instrument intercomparison, and
investigations of active and passive instrument data fusion. They are freely

Seasonal watershed-scale influences on nitrogen concentrations across the Upper Mississippi River Basin

Published: September 2020

Abstract. Humanity's footprint on Earth systems has engendered water quality impoverishment in streams, lakes, and coastal waters globally. In agricultural areas, stream nitrogen concentrations are often high where excess nitrogen fertilization and wetland loss via artificial drainage degrade water quality. While the watershed-scale influence of fertilization and wetland loss on annual nitrogen loads has been studied, little is known about the watershed-scale effects of these wetland losses at seasonal time scales. Here we apply machine learning and linear statistical analyses in a big data framework to improve understanding of the role wetlands play in influencing the seasonality of down-gradient water quality. We confirm the seasonal role of wetlands in improving water quality at the watershed scale and uncover evidence demonstrating the importance of contemporary watershed nitrogen inputs to in-stream total nitrogen concentrations [TN]. We observe that in the Upper Mississippi River Basin, United States, after the application of spring fertilizers, [TN] drops by 70 % from June to September suggesting the importance of seasonal nutrient loading. Our data mining approach affords exploration of the potential influence of numerous landscape and wetland hydrologic processes on [TN], some of which are shown to exert seasonal influence. Our counterfactual analysis–in which wetlands are restored to their historic extent–points to the substantial water quality benefits of wetland restoration, including particular water quality improvements in the spring when [TN] are highest. Water quality benefits due to wetland restoration would make water safer for human consumption and improve the security of aquatic ecosystems.
Accretion, retreat and transgression of coastal wetlands experiencing sea-level rise

Published: September 2020

Abstract. The vulnerability of coastal wetlands to future sea-level rise (SLR) has been extensively studied in recent years, and models of coastal wetland evolution have been developed to assess and quantify the expected impacts. Coastal wetlands respond to SLR by vertical accretion and landward migration. Wetlands accrete due to their capacity to trap sediments and to incorporate dead leaves, branches stems and roots into the soil, and they migrate driven by the preferred inundation conditions in terms of salinity and oxygen availability. Accretion and migration strongly interact and they both depend on water flow and sediment distribution within the wetland, so wetlands under the same external flow and sediment forcing but with different configurations will respond differently to SLR. Analyses of wetland response to SLR that do not incorporate realistic consideration of flow and sediment distribution, like the bathtub approach, are likely to result in poor estimates of wetland resilience. Here, we investigate how accretion and migration processes affect wetland response to SLR using a computational framework that includes all relevant hydrodynamic and sediment transport mechanisms that affect vegetation and landscape dynamics, and it is efficient enough computationally to allow the simulation of long time periods. Our framework incorporates two vegetation species, mangrove and saltmarsh, and accounts for the effects of natural and manmade features like inner channels, embankments and flow constrictions due to culverts. We apply our model to simplified domains that represent four different settings found in coastal wetlands, including a case of a tidal flat free from obstructions or drainage features and three other cases incorporating an inner channel, an embankment with a culvert, and a combination of inner channel, embankment and culvert. We use conditions typical of SE Australia in terms of vegetation, tidal range and sediment load, but we also analyse situations with three times the sediment load to assess the potential of biophysical feedbacks to produce increased accretion rates. We find that all wetland settings are unable to cope with SLR and disappear by the end of the century, even for the case of increased sediment load. Wetlands with good drainage that improves tidal flushing are more resilient than wetlands with obstacles that result in tidal attenuation, and can delay wetland submergence by 20 years. Results from a bathtub model reveals systematic overprediction of wetland resilience to SLR: by the end of the century, half of the wetland survives with a typical sediment load, while the entire wetland survives with increased sediment load.
Storm tide amplification and habitat changes due to urbanization of a lagoonal estuary

Published: September 2020

Abstract. In recent centuries, human activities have greatly modified the
geomorphology of coastal regions. However, studies of historical and
possible future changes in coastal flood extremes typically ignore the
influence of geomorphic change. Here, we quantify the influence of 20th-century man-made changes to Jamaica Bay, New York City, on present-day storm tides. We develop and validate a hydrodynamic model for the 1870s based on detailed maps of bathymetry, seabed characteristics, topography, and tide observations for use alongside a present-day model. Predominantly through dredging, landfill, and inlet stabilization, the average water depth of the bay increased from 1.7 to 4.5 m, tidal surface area decreased from 92 to 72 km2, and the inlet minimum cross-sectional area expanded from 4800 to 8900 m2. Total (freshwater plus salt) marsh habitat area has declined from 61 to 15 km2 and intertidal unvegetated habitat area from 17 to 4.6 km2. A probabilistic flood hazard assessment with simulations of 144 storm events reveals that the landscape changes caused an increase of 0.28 m (12 %) in the 100-year storm tide, even larger than the influence of global sea level rise of about 0.23 m since the 1870s. Specific anthropogenic changes to estuary depth and area as well as inlet depth and width are shown through targeted modeling and dynamics-based considerations to be the most important drivers of increasing storm tides.
Tracking geothermal anomalies along a crustal fault using (U − Th)∕He apatite thermochronology and rare-earth element (REE) analyses: the example of the Têt fault (Pyrenees, France)

Published: September 2020

Abstract. The Têt fault is a major crustal-scale fault in the eastern
Pyrenees (France) along which 29 hot springs emerge, mainly within the
footwall damage zone of the fault. In this study, (U-Th)/He apatite (AHe)
thermochronology is used in combination with rare-earth element (REE) analyses in order to
investigate the imprint of hydrothermal activity around two main hot spring
clusters (Thuès-les-Bains and St Thomas) and between them. The main goal
is to better define the geometry and intensity of the recent thermal
anomalies along the fault and to compare them with previous results from
numerical modelling. This study displays 99 new AHe ages and 63 REE analyses
on single apatite grains from samples collected in the hanging wall (18 to
43 Ma) and footwall (8 to 26 Ma) of the Têt fault. In the footwall, the
results reveal AHe age resetting and apatite REE depletion due to
hydrothermal circulation along the Têt fault damage zone, near the two
hot spring clusters, and also in areas lacking present-day geothermal surface
manifestation. These age resettings and element depletions are more
pronounced around the Thuès-les-Bains hot spring cluster and are
spatially restricted to a limited volume of the damage zone. Outside this
damage zone, new modelling of thermochronological data specifies the thermal
evolution of the massifs. The footwall model suggests the succession of two
main phases of cooling: between 30 and 24 Ma and a second one around 10 Ma.
In the hanging wall, little evidence of hydrothermal imprint on AHe ages and
REE signatures has been found, and thermal modelling records a single cooling
phase at 35–30 Ma. Low-temperature thermochronology combined with REE
analyses allows us to identify the spatial extent of a recent geothermal
perturbation related to hydrothermal flow along a master fault zone in the
eastern Pyrenees, opens new perspectives to constrain the geometry and
intensity of geothermal fields, and provides new regional constraints on the
cooling history of the footwall and hanging-wall massifs.

Process Reengineering in African Public Sector: Lessons From the Private Sector
Authors: Jacob Olufemi Fatile, , Sybert Mutereko , Etim Emma
Published: September 2020

Process reengineering (PR) is a newly introduced approach to process management; it pays close attention to all the processes that are related to the achievement of organizational objectives. Although originally developed for and applied in the private sector, PR is expected to constitute a handy tool for the transformation of work processes in public sector organizations (PSOs), especially in this era of information and communications technology. This paper x-rays PR in African public sector organizations (APSOs) with an emphasis on lessons to be learnt from the private sector. This paper adopts a descriptive approach, to validate and modify extant theoretical models that are relevant in explaining PR in APSOs. The paper observes that APSOs, unlike the private sector organizations (PrSOs), PSOs have failed in the adoption of PR as well as carrying out logically related tasks in such a way that well-defined results are achieved. It reveals further that poor PR in APSOs has been a clog in the wheel of achieving high performance, efficient service delivery, public satisfaction, efficient management of resources, and sustainable development in Africa. This paper concludes that APSOs can fully adopt PR if they cut down on excessive bureaucracy and learn more from the private sector in terms of readiness and adaptability to environmental changes and transformation as advocated by the contingency theory (CT). The paper recommends, amongst others, that there should be the availability of information technology (IT) infrastructure and the willingness on the part of government representatives to deploy new technologies through adequate support for information technology companies and the prioritization of IT application's needs for high system automation. Managers of APSOs should be given the power to effect changes when the need arises, without any form of influence. Also, there should be concerns about the future of PSOs, and citizens who are clients thereof should be held in high esteem and not to be treated as ‘people in need of favour’. Finally, APSOs should embrace radical changes associated with PR especially by ensuring that promotions are based on merit and not on seniority alone.
The Role of Apostolic Faith Mission in Zimbabwe in the Fight Against Coronavirus
Authors: Pavari Never
Published: September 2020

Practical theology, according to Stone (2002) posits that churches should care and sacrifice for the community. Consequently, Christianity has been handling epidemics for more than 2000 years. This paper seeks to assess the role that is being played by the leadership in Apostolic Faith Mission in Zimbabwe (AFMZ) in response to the COVID-19 pandemic. The term leadership in this paper refers to those in charge of the congregants and this includes church pastors, reverends, bishops and elders. Church leaders are people who play influential roles within their faith communities and the broader local community. They benefit from trust and exercise moral authority over members of their local faith community, and shape public opinion in the broader community and even at the national or international level. The paper argues that the church and its leadership play an important role in providing moral guidance to tackle COVID-19 and also to dispel fear that stalks communities alongside the disease. In order to evaluate the role that AFMZ leadership is playing in the fight against COVID-19, the paper employs a qualitative research approach in its exploration and analysis of data gathered through an online survey method. The paper found out that the church is playing a vital role in communities by communicating messages of hope in the midst of severe fears of COVID-19. It also found out that the church leadership is playing a vital role in changing people’s attitudes toward COVID-19 by providing in depth discussions of safety measures in times of the pandemic. Lastly, the paper found out that the church leadership is not doing enough on the practical matters like providing food to the most vulnerable groups in their respective communities and for quarantined patients, maintaining clear communication with families and ensuring that basic primary care is not undermined due to limited finances. The paper therefore recommends that more finance should be availed to church leadership especially from the main church coffers to enable them to meet the above-mentioned demands.

Este texto analisa as descrições dos três aplicativos de produtividade mais acessados nas lojas virtuais PlayStore e AppleStore. O objetivo é delinear quais discursos são acionados para incentivar os potenciais usuários a baixar os aplicativos, e como esses dispositivos são situados no âmbito de uma economia da informação. A análise mostrou três pontos principais: (1) os aplicativos são voltados à organização do tempo de produção, progressivamente indefinido; (2) a organização do trabalho é pensada em termos de organização pessoal, da qual deve decorrer a profissional; (3) há, em um dos casos, um sistema de pontuações e recompensas pela produtividade. Esses dados são analisados criticamente contra o pano de fundo das noções de “cultura empreendedora” e, sobretudo, de trabalho informacional.
Relato etnográfico sobre a participação da audiência em programa televisivo sobre saúde
Authors: Souza de Miranda Amanda
Published: September 2020

Este artigo tem o objetivo de analisar como a audiência do programa Bem Estar, exibido pela Rede Globo,participa do programa, transformando-se em co-autora das narrativas sobre saúde veiculadas diariamente na emissora de maior audiência do Brasil. Com base em uma experiência etnográfica e na análise de episódios do matinal, discute-se como essa interação, cuja particularidade é a mediação entre o saber popular e o saber médico, é um recurso recorrente e fundamental na estrutura narrativa do programa. A análise indica ainda que a seleção das questões está alinhada ao que o roteiro oferece como forma e conteúdo, mas acaba por hibridizar o popular às histórias médicas veiculadas a cada edição.

Published: September 2020

Este trabalho se propôs a identificar quais fatores influenciam a atitude acadêmica de estudantes do curso de graduação em Ciências Contábeis da Universidade Federal de Minas Gerais em relação às disciplinas de Estatística. Para o alcance do objetivo, foi realizado um estudo quantitativo e qualitativo, com a aplicação de questionários a 93 estudantes do mencionado curso, englobando a Escala de Atitudes Perante a Estatística (SATS), que apresenta quatro dimensões da atitude: afetividade, competência cognitiva, dificuldade e valor. Os resultados da pesquisa foram analisados por meio de análise qualitativa, análise descritiva, teste de correlação e testes de diferença de média: teste T de Student e teste F (Anova). Foi aplicado, primeiramente, o teste de Shapiro-Francia, verificando a distribuição normal das variáveis, para então optar-se por testes paramétricos ou não paramétricos. Em um segundo momento, foi realizada a análise de correlação e verificado que todas as dimensões da atitude apresentam forte correlação entre si, ao nível de 95% de confiança. Dentre as características demográficas, observou-se, de forma geral, que o gênero foi a única característica pessoal dos alunos que influenciou a atitude em relação às disciplinas de Estatística, em que alunos do sexo masculino apresentaram maior atitude. As demais características analisadas não representaram fatores preponderantes nos estudantes em relação à atitude perante a Estatística.

A pesquisa identificou quais as características de governança corporativa e econômico-financeiras que influenciam as práticas de combinação de negócios em empresas brasileiras. A amostra compreendeu 88 entidades pertencentes ao Novo Mercado. Os resultados encontrados com a aplicação da correlação de Pearson e da regressão logística demonstraram que empresas com maior tamanho são as que mais efetuaram combinação de negócios. Conclui-se, que a relação entre a combinação de negócios e o tamanho da companhia poderia estar assentada na possibilidade de que as empresas aumentando o seu tamanho, não estão sendo alvo de aquisições de outras empresas.
