Percept of Teachers Regarding Integration of Education for Environment and Sustainable Development in Primary Schools
Authors: Pehoiu Gica
Published: June 2019

Environmental education studies emphasize the importance of this type of education since small ages as a basis for developing appropriate attitudes and behaviour towards the long-term environment, increasing accountability and motivation to take action to protect the environment. Geography has an essential role in environmental education, given the interdisciplinary character of this science, which aims at the interaction between man and environment, so that many studies are devoted to how this discipline contributes to forming of this type of education.      The present paper focuses on applying a questionnaire among teachers, they being discipline holders of some schools in Dâmboviţa County (Romania), to highlight their perceptions, with the main reference to the concept of environmental education in primary school. Perceptual studies will therefore be useful in understanding the importance that respondents place on these issues, how the concepts of environmental education and sustainable development are focused to students, methods and techniques used predominantly in the undertaken activities.

Published: June 2019

The article deals with modern types of sources in pedagogical historiography. Studying sources is an integral part of any science. Taking into account that pedagogical historiography considers pedagogy development and pedagogical views of scholars, it is very important to trace recent trends in educational thought. But epochs are changing, and nowadays this process is very fast, so, new types of sources are appearing. Thus, it is relevant to explore these sources. Therefore, the purpose of the paper is to study modern types of sources in pedagogical historiography. The tasks are: to find out, distinguish and describe innovative types in pedagogical historiography sources in comparison with traditional ones; to deliberate the classification of the mentioned phenomena. Such research methods as analysis and synthesis in historiography, source studies, historiography and pedagogical source studies were used. The results of the problem study allowed drawing the following conclusions. Both modern and traditional sources can be divided into types, families and kinds. Two of three types of pedagogical historiography sources (namely oral and written) have their reflection in modern means of storage and transition information. Modern kinds of oral sources can be represented by oral scientists’ reports, speeches in debates, discussions of educational issues, on-line pedagogical conferences and webinars etc. However, some of them can exist in traditional forms too (they are scientists’ speeches; consultations of scholars; discussions of educational issues). All traditional families of written sources in pedagogical historiography (namely narrative, didactic and documentary ones) have their reflection in modern means of storage and transition information. All kinds of written sources can be found both in traditional and modern forms, the exception is blogs. All varieties of sources have important but not the same meaning for pedagogical historiography. The conditional classification of modern pedagogical historiography sources was deliberated and presented in the article.

The aim of the research was to compare the results of the thermal decomposition of organic matter using different research methods. Experiments were carried out to assess interpretation methods in the characterization of the generation potential of source rocks. The research was conducted for samples of Menilite shales, recognized on the basis of long-term geochemical studies as good quality source rocks. The samples represented the Menilite Beds of the Silesian Unit, taken from the outcrops in the Carpathians. Research using known methods: Rock-Eval pyrolysis (RE), thermogravimetric and calorimetric methods (TG/DSC), and pyrolysis methods combined with gas chromatography analysis (PY-GC), were performed on the same samples- both on rock samples, as well as isolated kerogen. Such integrated studies have so far not been conducted on any rock material. The applied research methods showed a significant comparability of the results obtained. A number of correlations were found between the parameters from individual methods, including: the amount of hydrocarbons separated during PY-GC in the temperature range of 300–650°C, and the parameter S2 from RE, and mass loss in the TG analysis in the same temperature range; S2 values of rock samples and kerogen with weight loss as a result of pyrolysis from TG/DSC analysis at temperatures in the range of 300–650°C; temperature values of the maximum peak S2 (Tpk2) of rock samples with the maximum mass loss temperature during TG analysis; residual carbon content (RC) from RE analysis of rock and kerogen samples with a mass loss as a result of burning residual organic matter from TG/DSC analysis at temperatures in the range of 650–1050°C. The mass loss determined during thermogravimetric analysis, combined with the percentage share of individual hydrocarbon fractions, in which the C9+ fraction is significant, confirms the high petroleum potential of the organic substance contained in the Menilite Beds. Comparative studies of pyrolytic methods: Rock Eval, TG/DSC and PY-GC have proved the compatibility of the results obtained with all methods. Each of the methods also makes it possible to obtain mutually complementary information relating to the TOC, the degree of thermal maturity and type of generated hydrocarbons and other non-hydrocarbon compounds. The conducted tests and performed correlations showed the usefulness of a set of thermal methods to obtain complete information on source rocks.
Pomiary dwuenergetycznej tomografii (Dual Energy CT) w celu badania skał

Published: June 2019

One of the first applications of X-ray computed tomography in geology took place in 1974. X-ray tomography (CT) allows non-invasive imaging of the examined objects. The result of a tomographic measurement is a spatial image, showing the changes in X-ray absorption value for each point of the examined object, which are a result of calculations during the reconstruction process. An important advantage of computer tomographs is the ability to test large objects (meter sections of the core) in a very short time, while the disadvantage is the relatively low resolution of the measurement. Each voxel in the tomographic image has a specific grey value, proportional to the linear attenuation coefficient, depending on the electron density and the effective atomic number averaged in the imaged space (the averaging range is determined by the resolution of the tomographic image). Two tomographic images registered at two different energies, allows the deconvolution of the images into two components: the first – dependent on the electron density and the second – dependent on the effective atomic number. The aim of this study is to show the possibility of using dual energy computed tomography (DECT) to litho-density characterization of rock cores. In order to use tomographic images to obtain the above-mentioned physicochemical values, it is necessary to standardize CT images. The paper presents the process of determining calibration coefficients, which are necessary to convert the values of absorption coefficients, which are a direct result of CT reconstruction, into density values and effective Z atomic number. The article presents the calibration process with the use of reference rock fragments. The values of the standard samples computed from the analysis of images were compared with the values determined by laboratory methods. An example of the application of results is presented on the examined part of the image of the sandstone core, containing a calcite-filled fracture.

La moral del juguete de Baudelaire y las maneras estético-sagradas de la mirada
Authors: Márquez Osuna Francisco
Published: June 2019

Baudelaire observa que si en verdad existe una dimensión sagrada en lo humano, ésta se manifiesta desde la niñez. Interroga, así, por el sentido de lo sagrado en la vida infantil, como si una obsesión por el origen de lo sagrado se apoderara de su palpitante pluma. Y si profundiza en la espiritualidad de los niños es para indagar en la relación intrínseca de lo sagrado en las artes, pues en ellas parece sobrevivir el pathos latente de los tiempos perdidos: el tiempo de la infancia y el tiempo del pasado cultural. Ante este semblante, ¿qué genealogías de la espiritualidad hacen viables las artes? Y, de esta forma, ¿cómo las artes expresan lo sagrado?

Experiencing myth through adaptation, destruction and experiment (a case of cognitive linguistic analysis of Arthurian fan fiction)
Authors: Sharapkova Anastasia
Published: June 2019

El artículo trata de las formas en que el mito artúrico existe en el mundo contemporáneo, observando la correlación entre la narrativa ontológicamente básica y el fenómeno recientemente evolucionado de la era digital: fanfiction. Se demuestra que el mito es una reliquia del pasado, pero una herramienta para conocer el mundo. Experimentar el mito procede a través de su personalización, adaptación. Las historias de fanfiction exploran los límites de posibles transformaciones, haciendo que el concepto sea diferente pero reconocible. Después de analizar historias que cambian una característica central del Rey Arturo, concluimos que las otras características se refuerzan y las ideas más abstractas se llevan al nivel lingüístico mediante la repetición de conceptos significativos como historia, leyenda, mito, héroe. El mito evoluciona a través de la experimentación con la imagen, reforzando las características estereotípicas, solo a través de la narración contada por la gente.

Background and objectives: The initiation of apoptotic death in cancer cells is the aim of many chemotherapeutic strategies. As many anticancer agents have been discovered in natural plant sources, the search for novel phytochemicals displaying anticancer activities continues at a tremendous rate. This study was conducted to evaluate the effect of extractable polyphenols (EPP); non-extractable polyphenols (NEPP); nobiletin (NOB); tectorigenin (TEC) and persicogenin (PERS) from Barhi date palm kernels (BDPK) extracts on the induction of apoptosis in human lung cancer A549 and colon cancer HT29 cell lines. Materials and Methods: The anticancer activities were determined using MTT and trypan blue exclusion assays. Flow cytometry analysis was performed to study the cell viability, cell cycle arrest and apoptosis. The underlying mechanism of apoptosis induced by crude extracts and the purified compounds was investigated using caspase-3, -8 and -9 assays and the mitochondrial membrane potential assay. Results: The findings indicate that both BDPK extracts and the purified compounds do exert induced cell death on A549 and HT29 cells. The results observed from MTT- assay and trypan blue exclusion indicate that the cytotoxic effects of both plant extracts and the three isolated flavonoids are dose-dependent with higher cell death after 72 hours treatment. Treatment of human lung and colon cancer cells with EPP, NEPP, NOB, TEC and PERSI induced late stages of apoptosis as there was evidence of the DNA degradation and high percentage of the cells population was situated at sub-G1 phase, indicating a high population of apoptotic cells. Conclusions: Study of the apoptotic mechanism demonstrated that EPP and NEPP exhibited dependent mitochondrial signalling pathway as seen with caspase-9 and induced receptor-mediated (extrinsic) apoptotic pathway as seen with caspase-8. Therefore, our results suggest that BDPK extracts and the three isolated flavonoids could be a good candidate for developing anticancer agents.
Interpolation of Instantaneous Air Temperature Using Geographical and MODIS Derived Variables with Machine Learning Techniques
Authors: Ruiz-Álvarez Marcos , Alonso-Sarría Francisco , Gomariz-Castillo Francisco
Published: June 2019

Several methods have been tried to estimate air temperature using satellite imagery. In this paper, the results of two machine learning algorithms, Support Vector Machine and Random Forest, are compared with Multivariate Linear Regression, TVX and Ordinary kriging. Several geographic, remote sensing and time variables are used as predictors. The validation is carried out using four different statistics on a daily basis allowing the use of ANOVA to compare the results. The main conclusion is that Random Forest with residual kriging produces the best results (R$^2$=0.612 $\pm$ 0.019, NSE=0.578 $\pm$ 0.025, RMSE=1.068 $\pm$ 0.027, PBIAS=-0.172 $\pm$ 0.046), whereas TVX produces the least accurate results. The environmental conditions in the study area are not really suited to TVX, moreover this method only takes into account satellite data. On the other hand, regression methods (Support Vector Machine, Random Forest and Multivariate Linear Regression) use several parameters that are easily calculated from a Digital Elevation Model, adding very little difficulty to the use of satellite data alone. The most important variables in the Random Forest Model were satellite temperature, potential irradiation and cdayt, a cosine transformation of the julian day.
Dialectic of Homochirality
Authors: Kholmanskiy Alexander
Published: June 2019

To solve the problem of the origin of homochirality of living systems and life itself, it is necessary to rethink the conceptual foundations of physics dialectically. The review shows how this can be done within the framework of the paradigm of energoforms, which sets the principles of construction and mathematical formalization of the Heraclitus primary element of matter. The algorithm for modeling energoforms and structures of elementary particles was created based on the laws of dialectics, electromagnetic induction and the rules of quantum physics. The algorithm allowed to calculate the parameters of chiral structures of neutron, proton, electron, neutrino and photon in the ground and excited states, as well as the parameters of more than one hundred nuclei. As an adequate solution to the problems of neutrino physics and the nature of the universal chiral factor, we hypothesized the instability of the low-energy solar neutrino and the biogenicity of its decay products – chiral energoforms. The hypothesis was based on correlations of seasonal and daily variations of solar neutrino flux, optical activity of aqueous solutions of sugars and metabolism of plants and animals. In humans, chiral morphofunctional features that limit homeostasis and the rhythm of energy-informational connections of the brain with the external environment were revealed. It was shown that the mechanism of sensitivity of living matter to the action of chiral factor is based on the ability to self-organization of its cooperative water-containing systems consisting of spin homogeneous chiral elements.
The Choir Books of San Giorgio Maggiore in Venice: Results of in Depth Non-Invasive Analyses
Authors: Ricciardi Paola , Mazzinghi Anna , Legnaioli Stefano , Ruberto Chiara , Castelli Lisa
Published: June 2019

This paper discusses a cross-disciplinary, international collaboration aimed at researching a series of 15th century choir books at the abbey of San Giorgio Maggiore on the homonymous island in Venice. Produced for the abbey itself, the books have never left the island during their 500-years history, thereby allowing a unique opportunity to analyse historic artefacts, which have undergone little modification over time. Prompted by ongoing cataloguing work on the manuscripts, a week-long analytical campaign using a combination of non-invasive analytical methods used in portable configuration allowed the comprehensive characterisation of ten volumes. The manuscripts’ palette and painting techniques were analysed using near-infrared imaging, reflectance spectroscopy in the UV-vis-NIR range, Raman spectroscopy, X-ray fluorescence mapping and digital microscopy. The paper will discuss the challenges linked to the fragility and the large dimensions of the volumes as well as the most interesting results of the investigation. These include the detection of unusual painting materials such as bismuth ink, as well as the discovery of a less homogeneous palette than originally expected, which prompted a partial revision of the attribution of the decoration in one of the volumes to a single artist.
Mathematical Basis for the Assessment of Antibiotic Resistance and Administrative Counter-Strategies
Authors: Diebner Hans H. , Kather Anna , Roeder Ingo , de With Katja
Published: June 2019

Background: Temporal changes of the proportional abundances of different antibiotics (e.g. mixing or cycling) is regarded as an effective administrative control strategy to reduce the prevalence of antibiotic-resistant pathogens in nosocomial infections. Although such a mixing strategy appears to be plausible, a rigorous assessment of its efficacy is lacking. In particular, a sound mathematical method that correlates temporal changes on both sides, i.e. the consumption of antibiotics and the prevalence of pathogens, is still pending. Methods: We adopt diverse measures of heterogeneity and diversity based on the concept of entropy from other fields and adapt them to the needs in assessing antibiotic resistance. Most important, we extent the measures such that they optimally account for the temporal changes in heterogeneity of antibiotics consumption and pathogen prevalence. Furthermore, we introduce a scheme based on linear regression for the assessment of associations between changes of heterogeneities on the antibiotics and the pathogen side. Results: A crucial part of our results is the derivation and provision of a sound mathematical basis to assess administrative control strategies against antibiotic resistance. As a showcase, we apply the derived methods to records of antibiotics consumption and prevalence of antibiotic-resistant germs from the University Hospital Dresden, Germany. Since the data has not been recorded in a controlled way, the application has to be understood as proof-of-concept. Besides the reasonable quantification of heterogeneities of antibiotics consumption and prevalence of pathogens, we show that a reduction of prevalence of antibiotic-resistant germs correlates with a change of heterogeneity of antibiotics consumption. Conclusions: Although an interventional study is pending, our mathematical framework turns out to be a viable concept for the assessment and optimisation of control strategies intended to reduce antibiotic resistance. Provided that an interventional or comparative study yields different time courses of controlled mixing strategies, the method is potentially suitable to determine optimal counter-strategies by means of statistical learning, aka the maximum entropy method.
Comparative Histological Study of the Stomach in Two Species of Iraqi Vertebrates (Magpie Pica pica L. and Small Asian Mongoose Herpestes javanicus E.)
Authors: Et al. AL –Nakeeb
Published: June 2019

A histological study showed the wall of the stomach in Pica pica and Herpestes javanicus consists of four layers: mucosa, submucosa, muscularis externa and serosa. Also, the present study showed many  differences in the histological structures of the stomach for each in both types. The stomach of P. pica consists of two portions: the proventiculus and gizzard, while the stomach of H. javanicus consists of three portions: cardiac, fundic and pyloric regions. The mucosa layer formed short gastric folds, named plicae. In the proventiculus of P. pica, sulcus is found between each two plicae, but the folds called gastric pits in the gizzard, which are full with koilin. Lamina properia in both types contained gastric glands (straight simple tubular glands) named superficial glands, as well as another gastric gland found in the submucosa layer of the proventiculus in P. pica only named deep gastric glands. The gastric gland in the stomach of H. javanicus contained: mucous neck cells and parietal cells positive to AB/PAS stains in cardiac portion, as well as chief cells in fundic portion, but pyloric portion had just mucous neck cells. Muscularis externa in both types formed two muscle layers: inner and outer layer.
Histological Changes in the Lung and Liver of Mice Treated with Brake Pad Particles
Authors: Et al. Ghaidan
Published: June 2019

In the present study, the effects of brake pad particles of lung and liver histological sections were evaluated for (60) adult male mice. The animals were divided into three groups ( A,B,C) according to the periods of exposure (4, 8, and 12) weeks respectively exposed to brake pad particles in addition to the control groups (F) exposed to fresh air only. A special inhalation chamber designed locally has been used to expose the animals. The exposure to brake pad particles was (2.228) µg/m³ for 30 min/day, 5 days/week for (4,8and12) weeks respectively.

The examination in group (A) of the histological sections of the lung showed the thickness of interalveolar septa.  Also, a congestion of alveolar capillary was marked indicating pulmonary emphysema. The infiltration of alveolar macrophages showed the engulfed foreign particles (pad particles) within their cytoplasm, and peribronchial fibrosis. Group (B) showed the presence of pad particles (anthracosis), whereas the bronchial tree showed bronchitis with the bronchus-hyperplasia of mucin-producing cells (epithelial hyperplasia). Still another section showed an infiltration of mononuclear leukocytes and focal lobar necrosis. The third group (C), in turn, revealed acute interstitial bronchopneumonia with peribronchial focal necrosis and mild pulmonary edema with alveolar anthracosis.

As regards the liver, group (A) showed mild central venous congestion. Group (B), on the other hand, gave acute hepatitis, congestion of the central vein hyaline degeneration and mitotic figure having 2-3 nuclei. Severe congestion of the central vein with vascular amyloid deposition and most of the hepatocytes revealed coagulate necrosis in group (C). These changing tissues increased with increasing the exposure periods and were clearer in group (C) which was exposed for 12 weeks.

The continuous exposure to brake pad particles lead to damaging important body organs tissues and effect on human health, these particles can be considered as a type of pollutants added to air pollutants in different cities of Iraq.
New Fluorometric Method for the Determination of Ketotifen Fumarate Using Continuous Flow Injection Analysis via ISNAG-fluorimeter
Authors: Et al. Turkie
Published: June 2019

A newly developed analytical method was conducted for the determination of Ketotifen fumarate (KTF) in pharmaceuticals drugs via quenching of continuous fluorescence of 9(10H)-Acridone (ACD). The method was applied using flow injection system of a new homemade ISNAG fluorimeter with fluorescence measurements at ± 90◦ via 2×4 solar cell. The calibration graph was linear in the range of 1-45 mmol/L, with correlation coefficient r = 0.9762 and the limit of detection 29.785 µg/sample from the stepwise dilution for the minimum concentration in the linear dynamic ranged of the calibration graph. The method was successfully applied to the determination of Ketotifen fumarate in two different pharmaceutical drugs. A comparison was made between the newly developed method analysis and the classical method using the standard addition method via the use of individual and paired t-test and F-test. It was noticed that there was no significant difference between the two methods at 95 % confidence level.
Efficacy of verum and sham acupoint catgut embedding in treatment of simple adult obesity: study protocol for a randomized, placebo-controlled trial
Authors: Zhou Yumei , Yan Bing , Yuan Wei-Qu , Yu Hai-Bo , Yang Zhuo-Xin
Published: June 2019

Background

Obesity has became a global health issue. The previous studies suggested that acupoint catgut embedding (ACE) might be a potential treatment option for obesity. In this study, we will conduct a rigorous and normative trial to determine the efficacy of ACE for obesity.

Methods/design

A total of 99 eligble patients diagnosed with obesity will be recruited. They will be randomly allocated to either the verum ACE group, sham ACE group or waiting-list group with 33 patients in each group. Each patient in two ACE groups will recieve 8 sessions of treatment over 8 weeks. The primary outcomes will be the reduction of body mass index after treatments. Secondary outcomes will include waist circumference, hip circumference, waist hip rate, body fat percentage, blood lipid level, as well as the subcutaneous fat area, visceral fat area and the scale assessments of World Health Organization Quality of Life. All outcomes will be evaluated at baseline, end of 8 weeks treatments and 3-month follow up. The evaluators and data analysts will be blinded to group allocation.

Discussion

The finding of this randomized, sham- and waiting-list-controlled trial will help to investigate the influence of ACE on clinical variables as well as visceral fat area, which will provide high-quality evidence on the efficacy of ACE for treatment of obesity.
Adaptation of IncX3 plasmid encoding blaNDM-4 within broad host range: A study from India
Authors: Choudhury Nargis Alom , Paul Deepjyoti , Das Bhaskar jyoti , (Chanda) Debadatta Dhar , Bhattacharjee Amitabha
Published: June 2019

Different variants of blaNDM has been reported across Indian subcontinent within diverse host range of gram negative bacilli. Most of their transferability depends on types of plasmid that encodes resistance determinant. IncX type plasmid is more recently known for carrying carbapenem resistance and NDM-4 variant is considered to have better hydrolytic property. This study aims to investigate the maintenance and stability of blaNDM-4 within BHR and transcriptional response. E.coli of clinical origin that harbor blaNDM-4 within IncX3 plasmid were used. Six different hosts were selected for gene transfer experiment, two strains of E.coli, K.pneumoniae, P.mirabilis, A.baumannii and P.aeruginosa. All the transformants and parent isolate were subjected for stability within new host. IncX3 plasmid encoding blaNDM-4 was transferred in host when imipenem (0.5µg/ml) screen agar was used for selection of transformants which are coharbouring resistance for aminoglycosides and quinolone. Plasmid was successfully expanded within all the six recipients till 55th serial passages. Transcriptional expression with NDM gene was variable for parent isolates though for new hosts it was showing random increased pattern in Proteus, E.coli, and DH5α. This could highlight, external carbapenem pressure helps in maintenance and expression of blaNDM-4 within different host range and epidemiological significance and will help in tracking the genetic vehicle responsible for their transmission,restricting their spread.
Meta-analysis of the endothelial protein C receptor rs867186 genotype in malaria
Authors: Yang Lin , Xin Ruilian , Guo Shanchun , Liu Mingli
Published: June 2019

The interaction between the P. falciparum erythrocyte membrane protein 1 (PfEMP1) on the surface of parasitized red blood cells (pRBC) and the endothelial cells (EC) receptors during P. falciparum infection results in the sequestration of pRBC from blood circulation. The amount of sequestration is determined by specific interactions among PfEMP1 and several host adhesion receptors, including intercellular adhesion molecule 1 (ICAM-1), CD36, and endothelial protein C receptor (EPCR). PfEMP1 is composed of multiple domains such as the cysteine-rich inter domain region (CIDR) and Duffy binding –like (DBL) domains. CIDRα1 competitively binds to EPCR with activated protein C (APC) and impair cytoprotective and anticoagulant effects by APC, which plays an important role in severe malaria (SM) pathogenesis such as cerebral malaria (CM) and severe malaria anemia (SMA). The strategy to inhibit EPCR binding to pRBC while to concomitantly strengthen its binding to APC may be crucial in restoring impaired protein C (PC) system’s function. The purpose of this study is to evaluate the association between severity of malaria and the EPCR genotypes as well as the soluble EPCR (sEPCR), and the study also addresses the physiological relevance of EPCR genetic polymorphism. In this study, we conducted meta-analysis on the eligible studies by comparing the frequency of EPCR rs867186-GG versus rs867186- GA and -AA genotype in SM, mild malaria (MM) or uncomplicated malaria (UM) patients and healthy individuals from Thailand, Uganda, Benin, Tanzania, and Ghana. We also determined the relationship between rs867186 genotype and sEPCR levels. Our results showed that the gene type of rs867186-GG is higher in MM/UM than in SM patients. SM patients carrying the rs867186-GG genotype have higher plasma soluble EPCR (sEPCR) levels than in rs867186-AG and rs867186-AA carriers. A significant difference is seen with the higher plasma sEPCR expression among MM/UM patients carrying the rs867186-AG genotype compared to those carrying rs867186-AA. Similarly, the rs867186-GG is associated with sEPCR level in healthy individuals. In conclusion, this meta-analysis demonstrates that pRBCs and EPCR interactions are associated with malaria severity, and treatments that block pRBC binding to EPCR via PfEMP1 CIDRα1 could be a potential therapy for SM.
Cultural Encounters in the Banking Sector of Serbia: The Case of Raiffeisenbank
Authors: Pešić Jelena
Published: June 2019

Тhis paper aims to examine the existence of cultural shock, differences and conflicts inside Raiffeisenbank, between personnel belonging to two national cultures (Austrian and Serbian), which could, conditionally, be regarded as representatives of ’’Western’’ and ’’Eastern’’ cultural models. The focus of the research was on elements of organizational culture, such as horizontal and vertical relationships, the type of leadership, the extent of formalization of procedures and work tasks, the types of motivations for different parties, but also on certain elements of work cultures (e.g., the respect of time limits, attitude toward extended working hours, etc.). Specific focus was placed on the role of cultural mediators, whose function was to mediate in the process of adaptation by the representatives of local national culture to novelties in the organizational culture imported from the outside, but also in the process of adaptation by foreigners to the local culture. The case study comprises a short history of Raiffeisenbank, analysis of written documents, and in depth interviews with individuals who could be regarded as “typical” in the examined cultural encounters.
Conspiracy Theories as Alternative Regimes of Truth and as a Universal Socio-Cultural Phenomenon
Authors: Diković Jovana
Published: June 2019

The paper analyzes the universal phenomenon of conspiracy theories, which, depending on specific social or political circumstances and on the social context in general, exist as alternative regimes of truth. In both the institutional and private spheres, conspiracy theories represent a kind of cognitive apparatus by means of which individuals and groups gain certain "information" and interpretations of those levels of reality that seem exclusive, hidden and controlled by supposed centers of power. The ultimate implications of conspiracy theories can be seen in the forming of prejudices, which, particularly in certain political circumstances and in combination with populist doctrines, can have a great impact on the public and private spheres. The potential of conspiracy theories, therefore, goes beyond mere intellectual intrigue and diversion for the masses, as they lend themselves to all kinds of political instrumentalization.

Published: June 2019

Apomictic grasses predominate among tropical forages, and specific breeding techniques are needed for their genetic improvement. The objectives of this study were (i) to generate hybrids by crossing tetraploid sexual and apomictic Paspalum simplex Morong genotypes, (ii) to develop a technique based on molecular markers for early identification of apomictic hybrids, and (iii) to determine the relationship between mode of reproduction and performance of hybrids. Crosses were made between two induced sexual and seven apomictic tetraploid plants. Identification of apomictic hybrids during seedling stage was performed using a marker linked to apomixis, and by flow cytometric seed analysis. Hybrids were evaluated under field conditions for plant diameter and height, initial growth, and seasonal regrowth during two consecutive growing seasons. Sexual tetraploid plants used as female parents behaved as allogamous, since 95% of the progeny had male‐specific markers. The ratio between apomictic and sexual hybrids differed from 1:8.7 to 1:0.6 among crosses, with a mean of 1:2.4. There was a 96% coincidence between the use of the apomixis‐linked marker and flow cytometric seed analysis. A technique based on the use of early DNA isolation and the amplification of a molecular marker linked to apomixis was developed. We found no overall difference between apomictic and sexual hybrids for the evaluated traits, except for fall regrowth in the first year, for which apomictic hybrids were superior. Generation of large tetraploid hybrid progenies is possible in P. simplex. Segregation for mode of reproduction depends on parents involved. Agronomic performance is not related to reproductive mode among tetraploid hybrids.

O objetivo deste artigo é identificar como os discursos oriundos do International Integrated Reporting Council (IIRC) são apropriados pela literatura acadêmica brasileira sobre o Relato Integrado. Para tanto, foram identificados e analisados 34 artigos publicados em periódicos e congressos. Para identificar os autores e instituições mais produtivos, mapeou-se a rede de coautorias da amostra. Através da leitura dos artigos, suas abordagens em relação à responsabilidade social corporativa e à contabilidade socioambiental foram categorizadas conforme proposto por Brown e Fraser (2006). Além disso, os artigos foram classificados também quanto a suas formas de apropriação dos discursos oriundos do IIRC e quanto a suas metodologias. Os resultados revelam uma rede de coautorias fragmentada e pouco densa, a ausência de abordagens críticas e uma hibridização entre as abordagens business case e stakeholder-accountability. Usualmente, os discursos oriundos do IIRC são reproduzidos sem qualquer tipo de contestação. Além disso, as obras mais referenciadas têm autores formalmente vinculados ao IIRC e possuem uma nítida orientação de divulgação do Relato Integrado. Dentre os procedimentos metodológicos, prevalecem avaliações da conformidade de relatórios corporativos às diretrizes do IIRC através de checklists. Em conjunto, tais evidências corroboram o argumento de que o campo acadêmico na contabilidade brasileira possui um baixo grau de autonomia em relação ao campo profissional, avançando na identificação de mecanismos através dos quais a influência do campo profissional se dissemina no meio acadêmico. Em termos práticos, os resultados desta pesquisa sugerem que o engajamento da comunidade acadêmica brasileira com o projeto do Relato Integrado não contribui para suprir a ausência de diversidade nas perspectivas sociopolíticas dos agentes que compõem as estruturas de governança do IIRC.Pesquisa ou Propaganda?

As demonstrações financeiras das companhias do ano 2016 foram submetidas a um novo conjunto de Normas Brasileiras de Contabilidade de Auditoria Independente (NBC TA), editadas pelo Conselho Federal de Contabilidade (CFC). Esse conjunto é representado por seis normas que compõem o chamado Novo Relatório do Auditor Independente (NRA). Dentre tais normas, destaca-se a NBC TA 701, que dispõe sobre a comunicação dos principais assuntos de auditoria no relatório do auditor independente. A partir dessa norma, os auditores passaram a evidenciar os pontos considerados de maior relevância no processo de auditoria da empresa, relatando as razões pelas quais foram considerados relevantes, como foram conduzidos os processos de análises e as suas respectivas conclusões. Destarte, o objetivo do presente trabalho consiste em analisar a percepção de auditores das Big Four sobre o Novo Relatório de Auditor Independente após a emissão da NBC TA 701. A pesquisa foi conduzida pelo método exploratório e qualitativo, através de entrevistas semiestruturadas com seis auditores. Os dados foram analisados através da análise de conteúdo. Os resultados apontam que o relatório dos auditores independentes se tornou mais informativo e melhorou a comunicação dos auditores com os órgãos de governança corporativa. Além disso, revelam que as principais barreiras encontradas foi fazer com que os clientes, principalmente as grandes empresas, pudessem entender efetivamente o que estava sendo aplicado nesse primeiro ano de implementação. Por fim, destaca-se que os assuntos de maior relevância e as áreas avaliadas como de maior risco, sob a ótica dos entrevistados, são sempre aonde há um maior grau de julgamento por parte deles e que geralmente se faz necessário envolver um especialista.

Searches for soil management systems that aim at maintaining soil quality are fundamental, along with sustainable agricultural and farming management. Thus, the aim of the present research was to assess soil parameters such as porous system, soil resistance to penetration, aggregate stability, relative soil density and the S index of an Oxisol under the conventional and no-till sowing management systems of corn production. They soils of the experimental areas were classified as a typical Oxisol with medium texture (LVd1) and typical Oxisol of clayey texture (LVd2). The experimental design was completely randomized split plot, with six replications. The plots (60 m2) consisted of six soil management systems (1 - SD1LVd1 = after one year no-till sowing; 2 - SD8LVd1 = after 8 years no-till sowing; 3 - SD10LVd1 = after 10 years no-till sowing; 4 - CCLVd1 = conventional sowing; 5 - SD12LVd2 = after 12 years no-till sowing; 6 - CCLVd2 = conventional sowing) and the subplots consisted of three soil layers (0-0.10, 0.10-0.20 and 0.20-0.30 m deep). The results showed that in three analyzed layers, the no-till sowing on medium texture Oxisol had higher densities. Treatments of medium texture Oxisol showed higher values of maximum soil density. This occurred because the clay content influenced a larger quantity of surface charges and specific surface area which decreased the susceptibility to soil compacting. The 12-year-old no-till sowing yielded the lowest corn productivity (5.9 Mg ha-1), probably due to the formation of compact layers, mainly near the soil surface.

Genetic, biochemical and physiological parameters can be changed by applying seaweed extract-based products. However, there is scarce information about the influence of seaweed extract on yarrow performance (Achillea millefolium L.), which is widely used in the folk medicine. Therefore, this study aimed to evaluate the effects of Ascophyllum nodosum extract on plant development (leaf and root biomass, and leaf area), physiological indexes (leaf weight ratio, and root: leaf ratio), secondary metabolite (phenolic compounds) content and antioxidant activity of yarrow. The experiment was carried out in a completely randomized design with 4 treatments (seaweed extract concentrations 0, 3, 6 and 9 mL L-1) and 10 replications. The higher concentration of seaweed extract caused higher total dry weight of plants (from 17.8 to 19%), especially due to increases in the root biomass (up to 28.5%). Only plants that received the highest concentration of seaweed-based product presented increments in the number of leaves when compared to the control plants (18.3 %). Furthermore, the use of A. nodosum extract 9 mL L-1 provided increases in the antioxidant activity and content of phenolic compounds in leaves (up to 30.44%). In conclusion, application of A. nodosum is a potential tool strategy to improve the quality of raw material from yarrow plants, since it increased the phenolic compound content and antioxidant activity in leaves, which are the plant organs commonly used in folk medicine.

Soil salinity is one of the main factors limiting the development and global agricultural productivity. Melon (Cucumis melo L.) is mainly produced in arid and semi-arid regions around the world, favoring the accumulation of soluble salts in the soil. Therefore, this study aimed to evaluate the emergence and vegetative development of melon genotype under different levels of soil salinity. The assessments were performed based on the exchangeable sodium percentage (ESP) at 0, 20, 25, 30 and 35%. The emergence was affected around 30 percentage points, by comparing the control and the highest dose (35%). The emergence speed and the emergence speed index parameters were also affected in a similar way, as well as the length and dry matter of the shoot. The growth of the plants was also affected by the saline stress, being superior in the control (0%) in relation to the treatments with NaCl. The leaf area increased between weeks 4 and 7 after the planting and was slightly superior in the control in relation to the plants submitted to saline stress (20, 25, 30 and 35% of exchangeable sodium). The melon is more sensible to the saline stress in the seedling emergence than in the vegetative development over time. The development of melon seedlings is mainly affected in exchangeable sodium values superior to 20%. The analyzed hybrid is sensible to the saline stress even in 20% of exchangeable sodium.
