A physicochemical, palynological and chronological analysis of a soil profile corresponding to a Haplic Chernozem (FAO, 2015) developed in the Ukrainian steppe allow the interpretation of recent environmental changes that have conditioned its formation. Uniformed under the blackening process, its surface horizon dark color contrasts with yellowish color loessic parental material; it is decarbonated and the organic carbon content on the surface is 2.24%.The texture is silty in surface but sandy in lower horizon denoting a clear wind selection and an energy change in aeolian sedimentation processes. The clays present similar values ​​in the three analyzed horizons. The presence of two discontinuities in the profile has made it possible to distinguish a very sandy blackened horizon of 2500 +/- 25cal BP chronologies from another silty surface and black chromas of age 1336–1256 cal BP. A total of fifteen pollen types have been identified; superficial horizon (A11) has a high presence of pollen of the Amaranthaceae type, the Poaceae are the most abundant and Quercus gender is identified. The sandy horizon (2A/B) shows Poaceas, Pinus, and Oleaceas presence together pollen of Rosaceas type (14%). Pollen data reveal vegetative changes in the three horizons with the presence of even non-existent species today, linked both to recent anthropic-climatic and holocene-type changes on a millennial scale since the last glacial period.
Characteristics of bottom fauna of small reservoirs of the Steppe zone of Ukraine
Authors: Poleva J. L.
Published: February 2021

The article is devoted to the study of the bottom fauna of small reservoirs of the Steppe zone of Ukraine and the search for approaches aimed at increasing fish productivity. The need to increase the fish productivity of reservoirs has put on the agenda the problem of increasing and improving the forage resources of fish. Increasing fish productivity by increasing stocks of industrially valuable fish species is possible by expanding aquatic invertebrate habitats by acclimatizing or relocating them to new reservoirs, introducing new species into all parts of the food chain that use food resources of reservoirs, i.e. by reconstructing benthic fauna. The main solution to this problem is the introduction and acclimatization of valuable forage aquatic invertebrates. Despite the fact that Ukraine has a very significant fishery fund of freshwater reservoirs, the state of many fisheries enterprises at the present stage is characterized by a decrease in production. The decline in fisheries production is largely due to a set of interrelated socio-economic and environmental limiting factors that emerged during the transition to market relations. The urgency of the problem and the biological productivity of water bodies are determined by the activity of aquatic organisms – an important part of which is the benthic fauna. Rational use of water bodies plays a significant role in the development of the country's economy and the preservation of the ecological situation.

Authors: Kushnerov O. I. , Bashev V. F.
Published: February 2021

New nanostructured Fe25B17.5Co21.35Nb3.65Ni25Si7.5 high-entropy metallic glass is synthesized by dint of splat-quenching technique. The estimated cooling rate is ~106 K/s. The coherently scattering domain size (crystallite size) of films of Fe 25B17.5Co21.35Nb3.65Ni25Si7.5 high-entropy metallic glass estimated by the Sherer formula is ~ 3 nm. The high-entropy metallic glass shows a high temperature of glass transition Tg ~ 800 K and the initial temperature of crystallization Tx ~ 863 K. After annealing to ~ 1010 K (above the crystallization temperature) and subsequent slow cooling, the amorphous films crystallize with the formation of several crystalline phases. The temperature dependencies of electrical resistivity of the Fe25B17.5Co21.35Nb3.65Ni25Si7.5 films indicate the occurrence of phase transformations. The phase transformation temperature (temperature of crystallization) is ~ 869 K. This value agrees well with the value obtained from the differential thermal analysis.

Published: February 2021

In the work, the nanocrystals ZnO and ZnO:Mn with a concentration of Mn 2 and 4 at.% were obtained by the low-temperature freeze-drying method. For this purpose, solutions of zinc acetate Zn(CH3COO)2∙2H2O and manganese one Mn(CH3COO)2∙4H2O were used. By means of XRD, it is established that nanocrystals (NC’s) have a pure phase and wurtzite-type hexagonal lattice, their size is d ~ 65 nm. The EPR spectra of the samples have a broad absorption line. It is due to the presence of a large number of intrinsic and impurity defects in the NC’s. These defects are the result of the destructive action of hydrogen, which is a product of the thermal decomposition of zinc and manganese acetates. It is shown that there is a relationship between the number of crystal lattice defects in the ZnO:Mn NC’s and their ferromagnetic properties at room temperature. Samples of ZnO:Mn with a concentration of Mn 2 and 4 at.%. have a specific magnetization value of Мs equal to 0.089 and 0.045 emu/g, respectively. The results can have great potential in spintronic devices and spin-based electronics.

Authors: Morozov V. M. , Magro V. I.
Published: February 2021

The stepwise transition in the coaxial waveguide is calculated by the integral equation method. To solve the problem, the entire region of field definition is conditionally divided into three partial areas for which the field components are recorded. A system of equations is obtained that allows one to calculate the reflection coefficient of a T-wave from this homogeneity. The geometric dimensions of the waveguide, which provide the minimum value of the reflection coefficient, are given.

Authors: Morozov V. M. , Magro V. I. , Trakhtman E. Yu.
Published: February 2021

An electrodynamics calculation is performed for an infinite waveguide antenna array in the form of open ends of waveguides, in the near zone of which a metal-dielectric structure is located. This metal-dielectric structure is located in the "Floquet channels" and is a combination of a dielectric coating over the antenna array and horns. In this case, the horns are not a continuation of the waveguides, but are located at some distance from them. The space between the waveguides and the horns is filled with a dielectric. A system of equations that allows calculating the reflection coefficients of incident waves in waveguides is obtained.

Published: February 2021

Clinical cases resembling strangles are regularly seen in some areas of Croatia. However, there are no data on the prevalence of infection and the clinical forms or geographic distribution of the disease. The aim of this study was to determine the seroprevalence of Streptococcus equi subspecies equi in horses resident in Croatia, in order to estimate the geographic distribution of infection. The study included 291 horse sera from the eight counties where the majority of Croatian horses are kept. Sera were tested by indirect ELISA (iELISA) for the presence of serum antibodies against S. equi protein A (SEQ_2190) and protein C (SeM). Positive horses were detected in all counties. Overall seroprevalence was 16.5 per cent (48/291), ranging from 7.1 to 29.6 per cent. A positive association was observed between the population size of the horses in the counties and the seropositivity rates: the larger the population, the higher the seropositivity. The results of this study suggest that S. equi infection is widespread in Croatia. Further investigation of the clinical manifestations, circulating strains and other characteristics of the disease in Croatia and raising awareness of the disease among horse owners are now required.

Published: February 2021

Abstract The ‘Niágara Rosada’ grape (Vitis labrusca) is the main table cultivar produced in the North and Northwest Regions of the Rio de Janeiro State. This cultivar presents greater rusticity and lower production cost than the cultivars of fine grape (Vitis vinifera L.) because it is more resistant to diseases and the absence of some cultural treatments. The research aimed to determine the economic affordability of the production of ‘Niágara Rosada’ grapes in the north and northwest regions of Rio de Janeiro state, by calculating the Net Present Value (NPV) and the Internal Rate of Return (IRR), and to identify the risk of viticulture, through the sensitivity analysis and the use of the Monte Carlo method. To collect the data, questionnaires, and interviews were applied directly to the wine producers on the technical coefficients and respective production costs of the grape in 1 ha. The results highlighted that viticulture could be a good alternative for the regions, with satisfactory profitability. The variables with the most significant effect on profitability were the sale price of the product, the cost of labor, and the price of packaging. The probability of winegrowers to obtain a negative NPV is 33.32%, considering an attractiveness rate of 6% per year.

Published: February 2021

Abstract Considering the importance of the functional assessment, a scale was developed to evaluate Executive Functions (EFs), State Regulation (SR) and Delay Aversion (DA) in adults, based on a children’s scale, and evidence of content validity was investigated. In Phase 1, items from the children’s version were adapted to generate the Inventory of Difficulties in Executive Functions, Regulation and Delay Aversion for Adults (IFERA-II), with 28 items of EFs (inhibition, working memory and flexibility), RS and DA. Analysis by judges verified the representativeness of the contents of the items. After adaptations, 18 adult participants responded to the IFERA-II and were interviewed regarding comprehension, need for examples and clarity of vocabulary. A new revision led to the preliminary version of the IFERA-II, the psychometric properties of which should be investigated.

Published: February 2021

Resumen El trabajo se centra en la variable subjetiva del aprendizaje: busca identificar las transformaciones psíquicas de seis niños en su tránsito por un dispositivo clínico mediado por cuentos (taller narrativo). El trabajo de campo se desarrolló en una escuela pública, con niños de 6 y 7 años, con pronóstico pedagógico desfavorable. Una herramienta informática organiza el análisis cualitativo y cuantitativo de la producción discursiva infantil. Los resultados ponen de manifiesto un incremento de dicha producción a medida que se fueron desarrollando los talleres y un menor requerimiento de participación del equipo coordinador. Sin embargo, se observa una tendencia decreciente de la producción imaginativo-reflexiva que motiva a focalizar el presente texto en esa dimensión y a dar cuenta de sus posibles causas.

ABSTRACT Objective The natural probiotic kefir is fermented milk, and may have effects on satiety and voluntary energy intake. This randomized crossover trial aimed to determine whether kefir, consumed with low- or high-glycemic index meals, affects appetite and subsequent food intake. Methods This is a cross-sectional study with families of farmers who supplied Programa Nacional de Alimentação Escolar from 2011 to 2016 in the city of Viçosa, Minas Gerais, Brazil. To assess Food Insecurity, the Brazilian Food Insecurity Scale was applied to the person responsible for purchasing and producing meals in the family. The nutritional aspect was analyzed through the measurement of hemoglobin to check for anemia among family members and using the household food availability survey, where it was possible to analyze the amount of calories available for consumption, as well as the origin and kind of food. Results 27 families were evaluated, totalizing 91 individuals. With the Escala Brasileira de Insegurança Alimentar, it was found that 25.9% of the families were in light food insecurty situation. When caloric availability was assessed, 11.0% of families were considered insecure. In contrast, 59.0% of families had high calorie availability per capita (>3000 calories). Of the total households, 14.8% had more than 50.0% of the calories available for consumption coming from their own production. The foods most commonly produced for self-consumption were fresh vegetables, which are the most common ones supplied to Programa Nacional de Alimentação. In addition, the main source of kilocalories for the families were fresh and minimally processed foods. The presence of anemia in at least 1 resident was detected in 29.6% of households, with a negative correlation between the hemoglobin value (g/dL) and the Escala Brasileira de Insegurança Alimentar score. Conclusion It appears that the majority of the families of farmers supplying Programa Nacional de Alimentação Escolar are in a situation of Food and Nutritional Security, both by Escala Brasileira de Insegurança Alimentar and by the household availability of food. However, we cannot ignore the percentage of insecure families, since this situation can lead to other problems. Therefore, it is necessary to constantly assess the family situation of Fodd Insecurty and encourage production for self-consumption so that it contributes to food availability and quality. For this reason, the we highlight relevance of programs that strengthen the production and commercialization of food from family farming.

ABSTRACT Objective To check the relationship of the degree of food processing with overweight and body adiposity in Brazilian adults. Methods Cross-sectional study with 670 adults (334 women and 336 men) aged 20-59 years in Viçosa, Minas Gerais, Brazil, based on population data collected using a questionnaire, 24-hour dietary recall interview, and anthropometric evaluation. Consumed foods were categorized into four groups: unprocessed or minimally processed foods, processed culinary ingredients, processed foods, and ultra-processed foods. Poisson regression models were used to assess the relationship between degree of food processing and overweight and body adiposity. Results The contribution of unprocessed or minimally processed foods to total energy intake was a protective factor for overweight in all quartiles. The contribution of ultra-processed foods to total energy intake was a risk factor for overweight in the highest quartile (prevalence ratio, 1.308; 95% confidence interval, 1.085-1.577). High energy intake from ultra-processed foods was a risk factor for excess adiposity in the highest quartiles. Conclusion Consumption of ultra-processed foods is associated with overweight and excess adiposity, whereas consumption of unprocessed and minimally processed foods is a protective factor for overweight.

Published: February 2021

Abstract The aim of the article was to analyze the purposes in life of young Brazilians. A total of 560 students, aged 15-19 years, from the five geopolitical regions of Brazil, answered an open questionnaire developed by the Stanford Center on Adolescence and adapted to the specificities of the research. The data were analyzed using the Theory of Organizing Models of Thinking, which enabled us to identify six models of purposes. Most young people expressed their life purposes as a natural course of life or as an idealized dream; most of them also presented a self-centered view of their purposes, focused on their own accomplishments. The results reveal an association between life purposes and identity of young Brazilians in the interaction with collective values, particularly regarding the overcoming of economic difficulties and financial achievements.

Effects of sulfates on adsorption-dispersing polycarboxylate behaviour with different carboxylic densities
Authors: He Yan , Liu Shuhua , Luo Qi , Zhang Yang , Wang Xiucai , Liao Gaoyu
Published: February 2021

The adsorption behaviour and dispersing capability of structurally different polycarboxylate superplasticisers (PCEs), with various carboxylic densities, was investigated in the presence of sulfates. The effect of sulfates on the early cement hydration evolution in the presence of PCEs with different carboxylic densities was also analysed. It was found that a higher proportion of carboxylate groups in the PCE backbone contributed to more intense adsorption of PCE onto cement grains, which contributed to lower sensitivity to the competitive adsorption of sulfate ions and hence produced higher resistance to the negative impacts of sulfates on fluidity and zeta potential. The addition of sulfates partially eliminated the retardation effect of PCE on cement hydration and boosted the nucleation of hydrates with increased cumulative hydration heat and higher heat evolution peak in the acceleration period. A higher concentration of sulfates led to a greater acceleration effect on cement hydration. However, PCEs with higher carboxylic density showed enhanced resistance to the impacts of sulfates on cement hydration.
Mitigating autogenous shrinkage using a combination of superabsorbent polymer and magnesia-based expansive additive
Authors: Fang Jianwei , Mo Liwu , Huang Bei , Deng Min , Wang Aiguo
Published: February 2021

Various strategies have been developed to mitigate the autogenous shrinkage of cement-based materials (CBMs), including internal curing and shrinkage compensation. However, the sole use of internal curing or shrinkage compensation is insufficient in many cases. In this study, magnesia-based expansive additives (MEAs) coupled with a superabsorbent polymer (SAP) were investigated as internal curing agents to mitigate the autogenous shrinkage of cement pastes. The internal relative humidity (RH), autogenous deformation and compressive strength of cement pastes containing two different types of MEAs and SAP were examined. The results showed that, with the incorporation of SAP, the RH in the cement paste was maintained at a higher level than that in cement pastes without SAP, and hence autogenous shrinkage was reduced. The combination of SAP and MEA provided very effective compensation for the autogenous shrinkage of cement paste. Moreover, the cement paste containing 8 wt% MEA and 0.2 wt% SAP produced a gentle expansion of 111 microstrain rather than shrinkage. This was attributed to the increased hydration degree of magnesia owing to the additional water supply provided by the SAP. This study provides a novel and efficient way to mitigate the autogenous shrinkage of CBMs.

Digital images are very popularly used for communications over the internet. Embedded information in the digital image has to be securely transmitted without any modification in the image. The biomedical telemedicine gains significant importance in information transmission and with increasing popularity with Tele-ophthalmology, requirement of medical data confidentiality and privacy also increases for data storage and secure transformation. The objective is to analyse  the bioimage encryption algorithms which provides security and privacy to the bioimages. In this paper retinal fundus image online available dataset have used. The proposed work is analysed by considering, three performance parameters such as PSNR, MSE and CR. The two different encryption algorithms namely block-based perceptual encryption (BBPE) and advanced encryption standard (AES) algorithm along with arithmetic compression have tested . The proposed work results tested on standard test images and retinal fundus images shows that the BBPE method attains PSNR of 27.58db , MSE of 3.20e+03 and CR of 4.27 for standard test images and 13.35db, 1.4046e+04 and 7.28 respectively for medical HRF images. The BBPE algorithm can be used in tele-ophthalmology and telemedicine applications.
Violencia contra las mujeres, un análisis desde los imaginarios del cuerpo femenino
Authors: Guachetá Elizabeth Ballen
Published: February 2021

Estudiar como la violencia derivada de la guerra, de la delincuencia organizada y, en general, del sistema de dominación patriarcal marca el cuerpo de las mujeres, es un reto para la sociología pues implica posicionar a aquel como objeto de estudio en un contexto cultural y socioeconómico caracterizado por la cosificación del cuerpo femenino, ícono de deseo y territorio donde se venga el honor de los señores de la guerra. De ahí que este análisis busque responder a la pregunta: ¿Cuál es el significado y el significante de la corporeidad femenina para tener una vida vulnerable y precaria? Una primera aproximación a la respuesta está entre el odio y la abyección en una sociedad jerarquizada en la cual las mujeres cumplen un rol de reproducción y producción de mano de obra o fuerza de trabajo junto con su cuidado y nutrición para mantener y fortalecer el sistema capitalista. De manera que el objetivo de este análisis se sitúa en comprender los contenidos y significados que la cultura ha impreso, a lo largo de la historia, y en todas las culturas, a los cuerpos de las mujeres. Éstos han constituido una cartografía de la violencia pues  desencadena una forma particular de circularlos y marcarlos como botines de guerra, debido a las relaciones de poder que se tejen en el conflicto armado, en el narcotráfico y la relación de pareja. Se busca llegar a entender, mediante la teoría comprensiva de Weber, cómo el cuerpo de las mujeres ha funcionado como territorio a ser conquistado violentamente por el género dominante .
LA RETROALIMENTACIÓN ENTRE PARES A TRAVÉS DEL BLOG EN LA CLASE DE INGLÉS LENGUA SEGUNDA AL SERVICIO DE UNA EDUCACIÓN INCLUSIVA
Authors: Gonzales María Lourdes Lira
Published: February 2021

La inclusión constituye un imperativo en todo el sistema educativo del cual la enseñanza de una lengua segunda (L2) en contexto universitario no está exento. La retroalimentación entre pares a través del blog en clases de escritura tiene el potencial de contribuir a dicha inclusión pues responde a las diferentes características, intereses, capacidades y necesidades de aprendizaje de los educandos. El presente artículo está dividido en dos secciones. En la primera se presenta una revisión de la literatura sobre la retroalimentación correctiva entre pares a través del blog en clases de escritura de inglés L2. En la segunda sección se presenta un estudio empírico realizado por Lira Gonzales y Nassaji (2019) sobre la retroalimentación entre pares a través del blog versus papel y se discuten los resultados de dicho estudio a la luz de la inclusión educativa.

Published: February 2021

Las prácticas pre profesionales constituyen un medio privilegiado para el desarrollo de competencias profesionales de los futuros docentes, siendo el análisis reflexivo un factor crucial en dicho desarrollo. El presente artículo reporta los resultados obtenidos en un estudio exploratorio descriptivo-interpretativo sobre el análisis reflexivo de los futuros profesores en las facultades de educación de dos universidades en Quebec (Canadá). Utilizando la tipología de retroacción de Rodet (2000) y los de niveles de reflexividad de Derobertmasure (2012), se plantearon dos preguntas de investigación: (1) ¿Cuáles son los tipos de retroacción ofrecidos por un supervisor después de escuchar los análisis de los practicantes en las cápsulas de video? y (2) ¿Cuál es la evolución del discurso de los practicantes a través de diferentes niveles de reflexividad, del principio al final de un semestre de práctica pre profesional? En este escrito se presentan y discuten las respuestas a ambas preguntas para finalmente proponer pistas de investigaciones futuras.
RUÍNAS DE REMANSO VELHO SOB A PERSPECTIVA DA MUSEOLOGIA: RELAÇÕES ENTRE COMUNIDADE E SÍTIO ARQUEOLÓGICO
Authors: Pinheiro Jarryer De Jesus
Published: February 2021

Após a realização do trabalho de conclusão de curso em Arqueologia e Preservação Patrimonial intitulada “O uso e transformação do espaço urbano: um estudo arqueológico da cidade de Remanso Velho, Bahia”, se evidenciou um conjunto significativo de ruínas da primeira sede do município de Remanso, chamada de Remanso Velho. Considerando a necessidade de compreender a perspectiva da comunidade atrelada a este sítio arqueológico, essa dissertação buscou conhecer e evidenciar as relações socioculturais existentes entre a comunidade da atual cidade de Remanso e o sítio arqueológico Remanso Velho. Dessa forma, apresentamos as principais ruínas, apontando suas funções enquanto eram estruturas arquitetônicas urbanas, bem como evidenciamos os processos históricos do surgimento até o seu desuso enquanto sede municipal. Em seguida, realizamos uma discussão teórica referente ao cenário estudado, apontando reflexões relativas ao patrimônio arqueológico e ao exercício museológico. Além de evidenciar os vínculos socioculturais existentes entre a comunidade e seu sítio arqueológico, o estudo realizado para esta pesquisa de mestrado também possibilitou caracterizar os processos históricos e os agentes que conduziram a construção dessas relações, a identificação do valor simbólico que é dado pela comunidade ao sítio arqueológico Remanso Velho e a identificação do papel desempenhado pelo sítio arqueológico na memória da sua comunidade. A problemática proposta como eixo delineador desta dissertação consiste no cenário no qual as ruínas de Remanso Velho não são reconhecidas como patrimônio arqueológico pelas instituições oficiais, tampouco se compreende a representatividade que esse bem arqueológico possui para a sua comunidade. Deduzimos, então, que tal condição colocaria essas estruturas fora das políticas públicas que possibilitariam o seu conhecimento e a sua salvaguarda, bem como dificultaria a implantação de processos de gestão social desse legado, colocando-o fora do eixo de pesquisas arqueológicas. Contrapondo esse cenário, foi proposta como hipótese que o fato de estar fora das políticas públicas oficiais não necessariamente impossibilitaria a sua comunidade de desfrutar de seu bem cultural, nas formas e maneiras por eles escolhidas. Conforme os resultados obtidos, confirmamos a hipótese apresentada e entendemos que a comunidade vinculada ao sítio arqueológico Remanso Velho utiliza o seu bem cultural na maneira que compreende os seus anseios.
Convivir con el coronavirus: ¿Cómo pueden las pruebas y el rastreo de contactos frenar la pandemia?
Authors: Savedoff Bill , Pinto Diana , Goyeneche Laura
Published: February 2021

Las pruebas y el rastreo de contactos son la columna vertebral de una respuesta eficaz del sistema de salud ante una epidemia. Sin embargo, en el caso del COVID-19, aunque la comunidad científica desarrolló pruebas de diagnóstico tan pronto se reconoció la amenaza pandémica, su producción se retrasó y la mayoría de los países no implementaron pruebas en cantidades suficientes o dentro de una estrategia nacional coherente. El objetivo del presente documento es identificar las estrategias exitosas en el uso de pruebas y el rastreo de contactos para informar a las políticas que puedan implementar los países de América Latina y el Caribe para desacelerar y controlar la pandemia. Se dan énfasis en las políticas de menor costo y las que toman en cuenta restricciones de recursos o en la oferta de insumos diagnósticos.
The Human Female Paradox: Biological Disadvantage Preimplantation, Biological Advantage, Thereafter
Authors: BR Migeon
Published: February 2021

The vital statistics show that human females outlive males at every biological stage. Once the embryo arrives in the uterus, more males die at every stage, at least until the eighth decade when the majority of survivors are female. Unexpectedly, the same statistics also show that more boys are born than girls, which is difficult to explain, because the sperm that determine the sex of the fetus, are not skewed toward males. Recently, new data reveal the reason for the increased number of male births; they imply the significant loss of females before the fetus arrives in the womb. Thereafter, there is an excessive loss of males – not only in utero but throughout their lives. One likely reason for the sex differences in fetal survival is the way that humans compensate for the sex difference in number of X chromosomes.
The age-related alerations in the enteric nervous system and their impact on peristalsis of the gastrointestinal tract

Published: February 2021

Constipation occurs more often in old patients, because the intestinal peristalsis decreases with aging. Constipation is caused due to impaired motility of the intestines, intestinal barrier damage and the imbalance between the absorption and secretion of water and electrolytes, as well as disturbed production and release of intestinal hormones, infiltration of the gastrointestinal tract with immune cells, excessive production of pro-inflammatory cytokines and the alterations in the functions of enteric nervous system.
In this review we will discuss the most important issues associated with the process of aging of the digestive tract, focusing on the enteric nervous system.

Revisitando o conceito da Nova Economia Institucional (NEI)
Authors: Strassburg Udo , Oliveira Nilton Marques de , Rocha Jr Weimar Freire da
Published: February 2021

O objetivo deste artigo foi apresentar o conceito da Nova Economia Institucional (NEI) com seus respectivos ambientes: institucional, organizacional, tecnológico, dos negócios e competitivo. Utilizou-se de um ferramental metodológico exploratório, à guisa da literatura. Os principais resultados sugerem que a Nova Economia Institucional teve sua origem com a evolução da Original Institutional Economics – OIE, tendo como proposta central as instituições. As instituições possuem a função de ser o principal regulador das atividades e interações humanas. O ambiente institucional é definido pelo conjunto de regras sejam elas formais e informais. O ambiente organizacional é composto pelas organizações que dão suporte para o funcionamento do sistema. O ambiente tecnológico está relacionado ao desenvolvimento e a necessidade de tecnologia que a organização possui. O ambiente de negócio tem avançado paulatinamente, com relação a redução da burocracia existente. Por fim o ambiente competitivo é aquele em que todas as empresas possuem as mesmas chances, mas somente irão ganhar aquelas que utilizarem melhor os recursos produtivos (físicos, humanos e financeiros).
