La responsabilidad social tácita. El caso de una hacienda y una cooperativa en el sureste de México
Authors: Rendón Cobián Marcela Victoria
Published: April 2019

El objetivo del trabajo es caracterizar la responsabilidad social tácita de las organizaciones y destacar la relevancia de las redes informales en su conformación. Dicho tipo de responsabilidad es propio de las organizaciones pequeñas, tradicionales y familiares, y se caracteriza por incorporar en ella aspectos afectivos, culturales y éticos, así como su falta de concreción en un documento formal. Se ilustra la propuesta analítica mediante el estudio cualitativo de dos organizaciones dedicadas a la industria del cacao en el sureste mexicano. Para tal efecto, se realizó un conjunto de entrevistas semiestructuradas, apoyándose además en observación participante y análisis documental. El principal hallazgo consiste en el descubrimiento de una modalidad de responsabilidad social de las organizaciones que no se presenta como una propuesta elaborada racionalmente sino como la expresión tácita de la búsqueda de una identidad social digna, respetuosa tanto del pasado y el futuro como de la cultura y la naturaleza. El trabajo abre una vía de debate sobre la importancia de recuperar valores culturales en la conformación de programas formales de responsabilidad social e incluye además una breve reflexión sobre el potencial de la generalización de los estudios de caso como estrategia metodológica para el estudio de las organizaciones.

Published: April 2019

O objetivo desta pesquisa foi compreender se existem relações entre os investimentos em pesquisa e desenvolvimento (P&D) e a divulgação de relatórios de sustentabilidade das empresas que são consideradas as que mais investem em P&D no mundo. A partir de uma pesquisa descritiva com abordagem quantitativa, os dados foram coletados por meio de três relatórios: EU Industrial R&D Investment Scoreboard, Global Reporting Initiative e Environmental Performance Index, que analisam 350 empresas e consideram 25 países. Os dados foram interpretados estatisticamente. Os resultados apontaram que as empresas que mais elaboram relatórios de sustentabilidade estão situadas em países que são considerados os mais sustentáveis do mundo. Entretanto, as empresas que mais investem em P&D não são as que mais elaboram relatórios de sustentabilidade, como também não houve relação entre lucratividade dessas empresas e relatórios de sustentabilidade. Pressupõe-se que, por razões estratégicas, as organizações optem por não destacar esses dados ao mercado, a fim de não municiar a concorrência com informações que podem vir a gerar interferência na vantagem competitiva. Por fim, foram apresentadas as limitações e oportunidades de trabalhos futuros.

Genome-Wide Analysis of Epstein-Barr Virus Isolated from Extranodal NK/T-Cell Lymphoma, Nasal Type
Authors: Lin Ningjing , Ku Wenjing , Song Yuqin , Zhu Jun , Lu Zheming
Published: April 2019

Background

Extranodal natural killer (NK) cell/T-cell lymphoma (NKTCL), a rare type of non-Hodgkin's lymphoma, has strongly been associated with Epstein-Barr virus (EBV) infection. However, there are no EBV genomes isolated from NKTCL, and the roles the variations of EBV strains play in the pathogenesis of NKTCL are still unclear.

Materials and Methods

In this study, whole EBV genomes from eight primary NKTCL biopsy specimens were obtained using next-generation sequencing, designated NKTCL-EBV1 to NKTCL-EBV8.

Results

Compared with the six mostly referenced EBV strains, NKTCL-EBVs closely resemble the GD1 strain but still harbor 2,072 variations, including 1,938 substitutions, 58 insertions, and 76 deletions. The majority of nonsynonymous mutations were located in latent and tegument genes. Moreover, the results from phylogenetic analysis of whole NKTCL genomes and specific genes demonstrated that all the NKTCL-EBVs were related to Asian EBV strains. Based on the amino acid changes in certain residues of latent membrane protein 1 (LMP1) and EBV-determined nuclear antigen 1 (EBNA1), all the NKTCL-EBVs were sorted to China 1 and V-val subtype, respectively. Furthermore, changes in CD4+ and CD8+ T-cell epitopes of EBNA1 and LMP1 may affect the efficacy for a cytotoxic T lymphocyte (CTL)-based therapy.

Conclusion

This is the first large study to our knowledge to obtain EBV genomes isolated from NKTCL and show the diversity of EBV genomes in a whole genome level by phylogenetic analysis.

Implications for Practice

In this study, the full-length sequence of Epstein-Barr virus (EBV) isolated from eight patients with nasal natural killer/T-cell lymphoma (NKTCL) was determined and further compared with the sequences previously reported isolated from other malignancies. Phylogenetic analysis showed that NKTCL-EBV strains are close to other Asian subtypes instead of non-Asian ones, leading to the conclusion that EBV infections are more likely affected by different geographic regions rather than particular EBV-associated malignancies. Therefore, these data have implications for the development of effective prophylactic and therapeutic vaccine approaches targeting the personalized or geographic-specific EBV antigens in these aggressive diseases.

O Brasil é o maior produtor mundial de cana-de-açúcar, com notável potencial para a produção de energias renováveis. O palhiço de cana-de-açúcar é um subproduto da colheita mecanizada que possui excelente poder calorífico podendo ser aproveitado para diversas finalidades na indústria. O presente trabalho teve por objetivo realizar a avaliação de desempenho de duas enfardadoras no recolhimento do palhiço de cana, equipadas com e sem sistema de trituração frontal. As enfardadoras foram tracionadas por um trator agrícola com 191 kW de potência, modelo 4x2 equipado com tração dianteira auxiliar (TDA). Foram mensuradas as variáveis de consumo de combustível (L h-1), velocidade operacional (km h-1), rendimento operacional do conjunto mecanizado (ha h-1), volume (m³) e massa (kg) dos fardos produzidos. Sem o sistema de trituração frontal (ST) os fardos apresentaram maiores volumes, em função da maior granulometria do palhiço recolhido, porém o consumo volumétrico de combustível e velocidade operacional do conjunto foi inferior em relação ao sistema com trituração (CT). A utilização do pré triturador frontal possibilitou um incremento de 25% no rendimento operacional do conjunto motomecanizado, porém aumentou a demanda de combustível em 38%.

O sucesso na implantação e desenvolvimento de uma lavoura somente é obtido quando a operação de semeadura é conduzida de forma adequada, com auxílio de tecnologias que facilitem seu monitoramento, minimizando assim, os erros na hora da deposição de sementes. O presente trabalho teve como objetivo avaliar sensores ópticos de semeadura com e sem fio, no monitoramento da distribuição longitudinal de sementes de milho, utilizando semeadoras de precisão em diferentes velocidades e mecanismos dosadores. O ensaio foi conduzido na Faculdade de Ciências Agronômicas da UNESP, campus de Botucatu/SP, e os tratamentos composto por: dois sensores ópticos (com fio e sem fio), cinco velocidades de deslocamento (4, 6, 8, 10 e 12 km h-1) e duas semeadoras (disco horizontal e pneumática). A coleta de dados experimento foi realizada utilizando uma semeadora-adubadora pneumática, tracionada por um trator de pneus, com 80 kW de potência no motor e uma semeadora-adubadora de discos horizontais, tracionada por um trator de pneus, com 89 kW de potência no motor. Os sensores foram instalados nas três primeiras linhas das semeadoras, posicionados no terço médio do tubo condutor de sementes. Para realizar a coleta de sementes, utilizou-se embalagens plásticas amarradas com abraçadeiras de nylon na saída dos tubos condutores, sendo as sementes coletadas, registradas pelos monitores de semeadura e contabilizadas por um contador automatizado modelo Seedburo 801 count-a-pak. O delineamento experimental adotado foi um fatorial 2x2x5, em blocos inteiramente casualizados, com quatro repetições cada. O sensor com fio apresentou acurácia superior. Pode-se adotar a velocidade de 8 km h-1 como velocidade ideal de trabalho. Quanto maior a velocidade de deslocamento, menor será a acurácia para ambos os sensores.

Considerando que a geração elétrica brasileira é alicerçada na produção hidráulica, associado à crise hídrica, o crescimento da demanda e a preocupação ambiental, fomentaram-se os estudos para encontrar mecanismos que minimizem os problemas que cercam a geração elétrica. Entre as formas de geração, está a proveniente de movimento de massas de ar, denominada eólica. Com o intuito de conhecer o potencial eólico sazonal do município de Cascavel, realizou-se um comparativo dos dados de velocidade do vento para descobrir qual estação pode render melhor aproveitamento de acordo com a velocidade média do vento local. Para tal análise, as velocidades médias do município de Cascavel foram obtidas através do Sistema Meteorológico do Paraná (SIMEPAR).Os dados foram apresentados em planilha eletrônica e analisados no programa BioEstat 5.0, onde realizaram-se testes estatísticos como o de Shapiro-Wilk e Análise de Variância ANOVA: um critério. Os testes foram aplicados objetivando a comparação das velocidades médias entre todas as estações em uma série histórica de 06 anos (2011-2016). Com as analises realizadas, pôde-se comprovar que na série histórica analisada, o inverno possui significante diferença de velocidade média sazonal, e portanto, pode proporcionar melhores condições de geração elétrica.

The association of chronic toxoplasmosis with mental disorders in general and with schizophrenia in particular was noticed in the mid-1950s. In subsequent years, the role of Toxoplasma gondii was established based on its ability to survive for long periods of time in the nerve cells of the brain. As a consequence, acute manifestations of the infection lead to psychopathic symptoms similar to schizophrenia and hallucinations. In the former USSR, and in other parts of the world, a number of studies were performed with respect to the association of latent toxoplasmosis and schizophrenia. However, with the dissolution of the USSR at the beginning of the 1990s, studies on the subject were halted due to financial problems and have resumed only recently. The reasons for the resumption of such studies in contemporary Russia are related to the progressively increasing incidence of schizophrenia over the last 25-30 years in the country. According to official data, approximately 550 000 persons reported suffering from the disease in 2014. There are reasons to believe that this is only a fraction of the real burden of the disease. Economically, it cost the state no less than approximately US $10 billion. The purpose of the study was to identify the level of toxoplasmosis seroprevalence in patients with verified diagnoses of schizophrenia in comparison to healthy people in Moscow City and in the Moscow region. A total of 155 persons constituted the experimental group and 152 healthy people were in the control group. An integrated approach to the diagnosis and comparison of data from the entire spectrum of serological markers of infection was used, including the detection of specific IgM and the determination of IgG concentrations and the IgG avidity index. It was found that among persons with neuropsychiatric disorders, the incidence of cases with chronic toxoplasmosis was higher than in the control group. The effect of toxoplasmosis was significant and similar for men and women. Further statistical analyses revealed that among patients with a diagnosis of schizophrenia, the incidence of chronic toxoplasmosis was significantly higher than in the control group. These data are in agreement with the results of similar studies in other countries.

Stories Behind a Minuscule Chinese Chip
Authors: Rezende Pedro Antonio Dourado de
Published: April 2019

We begin by examining the context of a political media campaign launched in October of 2018 in the scope of the North Atlantic Treaty Organization military alliance, aimed at disseminating among IT managers, with backing from general public opinion, perceptions of new risks in the use of electronic microchips fabricated by Chinese companies, for use in sensitive computational platforms.  We then contrast theses actions, which occur at the intersection of psychological and informational cyber fronts of the contemporary form of warfare (hybrid, 4th generation), with a similar type of risks inherent to the model for informatization of the federalized electoral process in Brazil, chosen more than twenty years ago and since frozen. Such contrast signals the presence of some form of geopolitical and/or ideological filtering, active in the mapping and evaluation of risks through scientific, legal and lay narratives on cibersecurity, regarding either embedded systems for military use, such as in weapons’ controls, or for civilian purposes, such as in electronic voting systems.
POLITICAL GEOGRAPHY OF XXI CENTURY
Authors: Masliak P.
Published: April 2019

The main regularities of the formation of the political map of the world and its individual regions in the XXI century.
Socio-geographical patterns in the field of political geography are determined by two objective factors. The first is that over time, the complexity of any territory increases. This is due to the fact that with the development of civilization and population growth, the territory of any taxonomic rank is constantly becoming more complex. More and more people and objects appear on it. Thus, smaller areas of size receive objective advantages over large ones.
The second factor is determined by the fact that on the political map of the world the number of countries absolutely does not coincide with the number of nations. The latter at least 50 times more. However, also absolutely objectively, no nation can fully realize its potential without the formation of a national state.
Proposed psychological-mental approach to the assessment of spatial-territorial factors in political geography.
The main contradictions between the action of objective laws of forming a map of the world in the XXI century and the principles of international relations.
Thus, on the basis of an objective statement that can be considered as axioms, we obtain the main interrelated patterns of forming a political map of the world in the XXI century. These include the pattern of imminent collapse of empires; the pattern of gradual increase in the number of countries on the political map of the world; the pattern of creation of national countries; regularity of the geopolitical pendulum of history.
In the XXI century the importance of spatial and territorial factors in the development of the political map of the world. Moreover, their implementation will take place against the background of psychological and mental local impulses. The development of individual countries will increasingly depend on the balance of their territories in a changing geopolitical space.
SIGNIFICANT DEPOSITS OF MINERALS IN THE TABLE D. I. MENDELEEV: NATIONAL DIMENSION
Authors: Bеidуk O.
Published: April 2019

The distribution of chemical elements and deposits of minerals is heterogeneous on the Earth. This heterogeneity reflects the following chain of levels of mineral resource supply of countries and territories: very low → low → average → high → very high.
Extreme links of this chain can be represented, for example, in the Republic of Korea (a very low level of mineral supply) and the South African Republic (very high level of mineral supply). Ukraine, according to various estimates, occupies the second (low) or third (middle) level in this rank. This publication serves as an objective basis for such assessments and aims as to demonstrate a certain raw material and energy independence of the quarry with respect to the provision of the most important minerals (this is demonstrated by the “mineral-raw” filling of the table by D. I. Mendeleev).
The systemic representation of Ukraine’s provision of mineral resources in general and regions (Donbas, Crimea, etc.) or economic regions (in some cases, in oblasts) provides a table «Deposits of minerals in Ukraine in the context of economic regions in the periodic system of chemical elements (tables by D. I. Mendeleev)».
The high level of provision of Ukraine’s territory with mineral resources in the context of economic-geographical regions has been confirmed. The periodic system of chemical elements (table by D. I. Mendeleev) is strengthened by data on the distribution of mineral raw materials and minerals in the context of economic-geographical regions of Ukraine. The highlighted problem has confirmed the high density of interdisciplinary connections (geography, geology, geochemistry, economics, regionalistics, zoning). The presented material reveals a decent level for developing strategies for socio-economic development of the regions, the given data can be implemented in the latest programs of reformed education of Ukraine.

Published: April 2019

The article reveals the main features of the development of the urban environment. The structure of the urban economy, the environmental aspects of the development of modern cities are considered. The economic progress of any city is closely related to the territory in which it is located. Prioritization of use by individual territories depends on changes in the socio-economic sphere. The main factors of transformational changes in the urban economy are highlighted, among them – the development of human society, which stimulates the emergence of new industries and technologies, the gradual loss of the cities industrial function due to the increasing influence of the services sector, concentration in the cities large numbers of the population, which causes the renovation of the infrastructure, development of service, cultural and entertainment facilities, the environmental degradation, which encourages cities to refuse dirty production and road transport. The ecological state of Chernihiv and the dynamics of its changes are characterized. Chernihiv belongs to the type of cities with relatively high level of industrial development. Industrial complex of the city, having significant share in the real sector of economy of the city, considerably influences the level and quality of life of city inhabitants. Industrial enterprises of the city went through a deep economic crisis, and beginning since 2002, stood on the way of post-crisis development, that means stabilization and rebirth of production. One of the peculiarities of industrial infrastructure of the city is that most of industrial facilities are located outside residential areas of the city. Analyzed the results of a survey among residents of the city on the idea of sustainable (balanced) development. According to the data, the population is characterized by insufficient information about the Sustainable Development Goals (SDGs). The results of a sociological study record the trend of the gradual spread of eco-regulatory practices among the population. First of all, it concerns energy conservation, cycling and rational use of natural resources.

The current study presents a fully qualitative palynological investigation carried out on the Raha Formation encountered from three wells in the Bakr Oil Field of the Gulf of Suez, Egypt. Around 30 species of pteridophytic spores, 26 species of angiosperm pollen, 24 species of gymnosperm pollen and 27 species of dinoflagellate cysts have been recorded. However, achritarchs, microforaminiferal test linings and freshwater algae are impoverished and sparsely documented throughout the Raha Formation. Two palynozones have been identified based on some stratigraphically significant pollen and spores, arranged from youngest to oldest: (1) Palynozone I (Classopollis brasiliensis–Tricolpites sagax Assemblage Zone) of late Cenomanian age; (2) Palynozone II (Afropollis jardinus–Crybelosporites pannuceus Assemblage Zone) of early-middle Cenomanian age. The distribution and ecological affiliation of specific palynomorph species, as well as various palynofacies parameters, are interpreted. A shallow marine environment from supratidal to distal inner neritic under proximal suboxic–anoxic to dysoxic–anoxic shelf conditions is reconstructed. Palaeobiogeographically, the absence of elaters from the recovered taxa is interpreted in terms of minor floral variation. This may be attributed to climatic and/or an environment-controlled niche establishment, which possibly was shaped by the existence of a physical barrier hindering the distribution of such type of elaterate parent plants.

Due to the growth of Cajazeiras in the last years, the city now has many university campuses, among them the Federal Institute of Education, Science and Technology of Paraíba (IFPB). Because of this growth in which the buildings take up the space of the vegetation, in conjunction with the necessity of the afforestation to mitigate the effects of the impacts on the environment, mainly the global warming, and to improve the living conditions in these places, this research underlines the identification and analysis of Cajazeiras campus’ afforestation. By the end of the research, it was possible to it was possible to determine the amount of trees in this campus, which adds up the number to 335 arboreal individuals. It was also pointed out that there is a predominance of exotic species, corresponding to a total of 78.14% of all arboreal individuals on campus. Since native species are a small minority, tree biodiversity is compromised, as exotic species predominate and there is a considerable percentage of invasive alien species.
Convergencia municipal en México con modelos de econometría espacial (1999-2014)
Authors: Rodríguez-Gámez Liz Ileana , Cabrera-Pereyra José Antonio
Published: April 2019

Comúnmente los estudios de convergencia en México no consideran la dependencia espacial entre áreas vecinas y solo unos cuantos de estos comprueban la hipótesis en el nivel municipal. Por ello el objetivo es comprobar si la convergencia (absoluta y condicional) ha ocurrido entre los municipios mexicanos durante el periodo 1999-2014 y evaluar si la contigüidad geográfica influye en el proceso. La evidencia permite concluir que los municipios pobres crecieron económicamente más rápido que los ricos, particularmente en el último quinquenio del periodo de estudio, y la dimensión espacial resultó ser un elemento cuya importancia se redujo con el tiempo; los anteriores resultados anticipan un crecimiento regionalmente más autónomo de las economías en años recientes.
Cognitive Assessment in Adult Cardiac Arrest Survivors: What Is Known and How Shall We Move Forward?

Published: April 2019

Background: Cardiac arrest (CA) remains the leading cause of premature deaths. Survivors often suffer from ischaemia-reperfusion injuries,which lead to neurological damage, cognitive impairment and psychosocial problems. While most survivors have to be assessed and deemed neurologically and functionally fit enough before discharge, adequacy of cognitive function is often neglected. This leads to problems with memory, attention, and executive function that are important for daily living. Aim: This study aims to provide an overview of existing literature regarding the use of cognitive assessment in adult CA survivors. Methods: A scoping review was conducted. Results/Findings: 62 articles were included and the existing relevant literature on the use of cognitive assessment can be mapped into the following themes: neurological–cognitive–psychosocial sequelae, effects of therapeutic hypothermia, prediction of cognitive function, adequacy of cognitive assessment tools, and effectiveness of post-CA rehabilitation interventions with cognitive domain. There is currently no consensus on the cognitive screening tool for cardiac arrest survivors although it is clear that they suffer from cognitive impairments especially memory and executive function. Conclusion: Routine cognitive testing should be part of follow-up care especially alongside cardiac rehabilitation to enhance patient outcomes and secondary prevention through complex self-care. This may decrease mortality, morbidity, and disease burden on an individual, national, and even global level.

Published: April 2019

Background: Undergoing general anesthesia and pneumoperitoneum could affect the lung function and comprise oxygenation in laparoscopic cholecystectomy patients. Position of patients after surgery may affect lung function of these patients. Aim: To observe the effect of semi-recumbent position on blood oxygen saturation (SpO2) in postanesthetic patients after laparoscopic cholecystectomy. Methods: A number of 225 patients who admitted to postanesthetic care unit after laparoscopic cholecystectomy from September 2016 to May 2017 were randomly assigned into the intervention group and the control group. The intervention group adopted a semi-recumbent position with head bed elevation by 10 to 20°, while the control received a supine position without lying on a pillow. Both groups received routine postanesthesia care. Data on SpO2 before and after extubation were collected. Independent t-test was used for data analysis. Results: There was no vomiting and cough reactions before and after extubation in both groups. Intervention group reported a significantly higher level of SpO2 at 1 minute and 30 minutes after extubation, compared to the control group (both ps < 0.05). Conclusion: Semi-recumbent position with the head bed elevation could significantly increase the SpO2 level of postanesthetic patients, thus ensuring the safety of patients when removing the endotracheal tube.

The experimental results showed the impact rendered by different rates of organic fertilizers in the kind of poultry excrements on crystallochemical parameters of minerals containing in the fine-dispersed fractions (less than 1, 1-5, 5-10 mkm). The considerable changes induced by increased rates of organic fertilizers take place in the ratio between the basic mineral phases and the crystallochemistry of minerals of the clay fraction as the most functional part of soil. One should indicate that the content of the clay fraction decreases, the layered silicates are destroyed and transformed as affected by higher rates of potassium and ammonium, fixed by mixed-layered formations with smectite pockets. The functionally inert minerals such as quartz, feldspar, plagi-oclase and mica of dioctahedral type are accumulated.
