Published: February 2020

The management of spatial arrangement in soybean culture (Glycine max L., Merrill) from seeding density and row spacing is an important tool that contributes to yield growth. The objective of this study was to evaluate the influence of spatial arrangement in the development and the production components of soybean in the Piauí Cerrado savanna. The experimental design was completely randomized, with subdivided plots and four replicates. The main plots consisted of different row spacing (17.5 cm, 25 cm, 50 cm and 76 cm) and subplots consisted of plant populations as follows: recommended (280,000 plant/ha); 50% below recommended; 50% and 100% higher than recommended. The subdivided plots had six lines of five metres in length. The highest growth component values (plant height, stem diameter and number of nodes) were observed in the larger spacing (50 cm and 76 cm) and lower populations (recommended and 50% below recommended). The highest component yield values (number of grains per pod, number of grains per plant, number of pods per plant, weight of one thousand seeds and productivity) were observed in the larger spacing (50 cm and 76 cm) and in the recommended population for the cultivar.

Published: February 2020

The evaluation of the root system is important for better understanding the effects of nutrient management on soil and plant nutri-tion. However, root system studies and culture are slow and show low accuracy. In this context, digital image processing may be an alternative. The objective of this research was to develop a computational method to assist evaluation of the soybean root growth. Initially, the free and open access software, available at: http://rm.deinfo.uepg.br/, was developed in Java platform with the OpenCV library supply through the plug-in JavaCV. To evaluate the software, copper wires with 10 mm, 20 mm, and 50 mm of length manually measured using callipers. They were scanned with a resolution of 300 dpi and then images were loaded in the software. Variation coefficients between 0.01 and 2.99 % were obtained. Subsequently, the samples of soybean roots were scanned and the results of developed software and Safira software were correlated with those from the line-intersect method. The determination coefficients (R² = 0.999) of the developed software, on average, were better than those obtained with Safira software (R² = 0.733), when compar-ing with the line-intersect method. Therefore, the proposed method was accurate for length measurements of soybean roots.

Published: February 2020

This research aimed to evaluate the maize grain yield and forage of grass species under intercropping system using nicosulfuron herbicide. In order to assess the parameters related to maize, a randomized block design was defined. The treatments were arranged in a (5 × 2+ 1) × 2 factorial design with four repetitions resulting in 11 treatments, where maize was cultivated under intercropping condition with different forage species (5) (Brachiaria brizantha cv. Marandu, Piatã, Xaraés, Brachiaria ruziziensis and Panicum maximum cv. Mombaça) and maize monoculture (1) as control treatment, with and without nicosulfuron herbicide application (2) in two growing seasons (2014 and 2015). The off-season intercropping of maize with tropical forage grasses with and without herbicide suppression decreased maize grain yield. The suppression with nicosulfuron herbicide decreased the dry matter production of forage grasses. Intercropping of P. maximum cv. Mombaça with maize showed higher decrease in maize grain yield. On the other hand, it showed higher forage grasses production for livestock feeding. B. brizantha cv. Piatã was the forage which less affected maize grain yield under intercropping, even with absence of nicosulfuron suppression. Off-season maize under intercropping with tropical forages can be used to recover degraded pastures; increasing forage dry matter production for livestock, remaining the soil covered with straws with possibility of no-till seeding for the next cultivation.

The rubber tree is a species native to the Amazon biome of great economic importance. Analyzing the soil physical attributes allows for quantifying the impact of different management practices on the soil properties and the yield of rubber plantations. The present experiment was developed on Red-Latosol soil cultivated with rubber tree (Hevea brasiliensis) since 2013. The experiment was set up as a factorial (2x3) design with two rubber-tree clones (PB 312 and RRIM 600) and three management strategies (organomineral fertilizer - poultry litter; mowing followed by mineral fertilizer application; green manure - pigeonpea [Cajanus cajan], as a cover crop) applied annually, with five replicates. Treatments were applied annually but the soil samples were collected at two times: firstly in 2015 (T1) and subsequently on 2016 (T2). Results revealed a reduction of microporosity, macroporosity, and total porosity and an increase in soil density with depth. However, no significant difference was detected across the management strategies for any of the evaluated traits. The different management strategies did not significantly influence the rubber-tree trunk circumference, suggesting a need for further evaluations throughout the entire development of individuals so that the response of this species can be quantified.

Published: February 2020

Crop residues left on the soil function as a nutrient reservoir and as a ground cover in agricultural systems. The aim of the present study is to assess the chemical alterations in the soil after the decomposition of different amounts of straw from corn as second crop. The climate of the region is classified as hot tropical and the soil is categorized as Red-Yellow Latosol (Typic hapludox) in the cerrado-amazon ecotone. The experiment was set up in randomized blocks in September 2013 after harvesting the second crop corn, comprised of corn straw rates (0, 14.18 and 42.54 t ha-1) with six repetitions. The content of macronutrients, H+Al, pH and base saturation in the soil profile were assessed. The straw rates were added to litter bags and stored on the soil, where they were kept for 154 days throughout the rainy period. Subsequently, the soil characteristics were assessed in layers 0 to 0.05, 0.05 to 0.10, 0.10 to 0.15, 0.15 to 0.20 and 0.20 to 0.40 m. The Ca+2 and Mg+2 elements were only released by the straw on the first 0.05 m of soil. However, K circulated in the soil profile reaching depth of 0.40 m. There was reduction in K+ saturation in treatments without straw. No alterations were observed in the other nutrients and studied attributes. According to the results, it is important to distribute the cultural remains of maize homogeneously in the area during harvesting to avoid the appreciation of soil fertility spots, especially of K.

The aim of this study was to evaluate the effect of salt stress on the contents of inorganic and organic solutes, pigments and essential oil in two basil genotypes cultivated in hydroponic system. The experiment was carried out in a greenhouse. Treatments were distributed in randomized blocks, in a 2 × 2 factorial arrangement, corresponding to two contrasting genotypes (‘Toscano folha de alface’ (TFA) and ‘Gennaro de menta’ (GM)) and two salt levels (0 - control and 80 mM NaCl), with six replicates. The Na+, Cl- and K+ accumulation in the leaves, stem and roots did not differ between genotypes. Salt stress increased free amino acids accumulation in the leaves of the TFA genotype. The proline content increased in the roots of both genotypes. However, in GM genotype, the proline content (3.12 mmol g-1 dry mass (DM)) was around 2-fold greater when compared to TFA genotype (1.48 mmol g-1 DM). The salt stress increased the photosynthetic pigments content only in the GM genotype. Inorganic solutes and photosynthetic pigments content are not good indicators of salt-tolerance in the studied genotypes. Under salt stress, there was increase in oil content in GM genotype, while the TFA genotype showed a decrease compared to control treatment. In spite of showing lower oil content, the TFA genotype showed higher yield and productivity of essential oil compared to GM under salt stress conditions.
Mycoplasmal pneumonia of swine: Update and importance of the disease
Authors: TARASIUK KAZIMIERZ
Published: February 2020

The paper provides an overview of updated knowledge on this common disease with a strong impact on pig production efficiency. Mycoplasma hyopneumoniae (Mhp), the etiologic agent of the condition, is the smallest self-replicating bacteria, distinguished from most other bacteria by the lack of a cell wall. Colonization of the respiratory cilia is a unique feature of Mhp, which results in a persistent presence of Mhp in the airways and creates a population of infected asymptomatic animals that continually expose other pigs to infection. The economic consequences of a long-term persistence of infection within the herd include a chronic reduction in feed efficiency and increased opportunity for co-infection with other respiratory pathogens, leading to PRDC (porcine respiratory disease complex) syndrome. Chronic Mhp infection in the form of a respiratory disease with high morbidity and low mortality has been estimated to affect up to 70% of pigs worldwide. Diagnostic tools include clinical diagnosis, examination of gross lesions and histopathology. Mycoplasma hyopneumoniaespecific laboratory tests are critical to identify asymptomatic carriers or to detect antibodies as a sign of endemic infection. Tools that demonstrate the presence of Mhp rely on visualizing the organism (culture, FIA) or on detection of nucleic acid (PCR) or antigen specific for that pathogen (ELISA). Control of Mycoplasma hyopneumoniae has been attempted by several widely practiced methods. These include sow vaccination programmes, early vaccination of suckling piglets, use of antibiotics at peak transmission times, introduction of piglet flow in the all-in/all-out system and a segregated system of pig production. Several Mhp elimination protocols have been developed and can be implemented to eradicate this pathogen from the herd. One of them is a partial depopulation procedure, which consists in depopulation of pigs below 9 months of age. The other animals are subjected to medication.

Published: February 2020

Data are presented concerning vaccines used in the prophylaxis and control of some viral and bacterial infectious diseases of swine, particularly against: MPS, PRRS, PMWS CSF, AD, SI, E. coli, Cl. perfringens type C and A and oedema disease. The lower efficacy in immunization of inactivated vaccines is stressed. However in case of live vaccines against PRRS this is not always the case since also live attenuated vaccines deliver unsatisfactory results of immunization. This is explained by frequently occurring genetic changes in the genome of the field PRRSV strains in comparison with the strain or strains being in the vaccine. Vaccines against PMWS are characterized, underlining high efficacy of the vaccines in the Baculovirus system. After withdrawing from field use against CSF the vaccines Lapest and Cellpest a recombinant vaccine against CSF was introduced for control of this disease. A recombinant vaccine against AD of swine is mentioned, which was successfully used in eradication program in Europe. Of high practical value is mentioned a vaccine against SI containing subptypes H1N1, H3N2 and H1N1. Referring to vaccines against viral diseases of swine marker vaccines were mentioned enabling differentiation of animals infected from vaccinated (DIVA strategy). At the beginning of the XXI century several new and effective vaccines were developed, produced and used against diarrheal diseases of different etiology and for the first time against oedema disease. The role of strategy of vaccination depending on the characteristic of the infectious disease, the vaccine and the production system of swine is present.

A contabilidade como ciência da informação tem um papel cada vez mais importante na promoção do Desenvolvimento Sustentável, pois, sua forma sistemática de registro e controle fornece dados à empresa sobre gastos e investimentos com o meio ambiente bem como a possibilidade reduzir custos e avaliar o impacto socioambiental do negócio. O presente estudo pretende colaborar com a divulgação e o conhecimento de metodologias para o cálculo de emissões de carbono em empreendimentos de pequeno porte, com ênfase no consumo de energia elétrica, tendo por base um salão de beleza. A pesquisa, exploratória, aplicada e descritiva, utilizou pesquisa telematizada e observações in loco para o estudo de caso, com um inventário dos equipamentos eletroeletrÿnicos e entrevista não estruturada da gestora/ proprietária do salão para identificação de aspectos subjetivos e detalhamento complementar. Recentemente o Brasil assumiu o compromisso de reduzir em 37% as emissões de gases causadores do efeito estufa entre 2005 e 2025 e em 43% até 2030. Contudo, o cálculo da pegada de carbono nem sempre compatível com as prioridades e realidade das micro e pequenas empresas, o que justifica este estudo, que apresenta ideias preliminares para contribuir na minimização dos impactos ambientais decorrentes das operações com equipamentos que utilizam esse recurso natural. Os resultados apontam a possibilidade de redução nas emissões de CO2 com pequenas intervenções, por exemplo, no projeto de iluminação do ambiente, com a substituição de lâmpadas incandescentes por LED, possibilidade para a criação de políticas públicas de incentivo ao consumo sustentável no segmento. Considerando que um reforço para a responsabilidade ambiental corporativa é a possibilidade de ter benefícios tangíveis, tais como aumento do lucro ou da redução de custo, o presente trabalho mostra uma maneira simples de ter esse retorno e ao mesmo tempo colaborar para atingir tanto as metas da PEMC e PNBMC quanto o compromisso de Contribuições Nacionalmente Determinadas Pretendidas brasileiras da COP21.

Tributo é elemento inerente à existência do Estado, necessário a organização da sociedade e ponto crucial da relação Estado-cidadão. No Brasil o segmento das micro e pequenas empresas tem fundamental importância no ambiente econÿmico, pois de acordo com pesquisas do SEBRAE representa 98% do número de empresas abertas no País. Diante dessa realidade o presente artigo tem como objetivo identificar qual é a percepção dos micro e pequenos empresários na cidade de São Paulo em relação aos tributos cobrados no Brasil. O estudo apresenta uma pesquisa de campo junto a diversos empreendedores situados na cidade de São Paulo para identificar sua percepção em relação à carga tributária brasileira. O resultado dessa pesquisa demonstra que apesar da maioria dos micro e pequenos empresários terem um grau de instrução alto, têm pouco conhecimento com relação ao tema.

Authors: Lima Luciana Campos , Lima Juliana Popp Barbosa
Published: February 2020

As empresas de pequeno e médio porte com caráter familiar tem sido objeto de estudos nos últimos anos, especialmente sobre o tema sucessão, por ser um processo extremamente crítico para a longevidade e sustentabilidade da organização. No entanto, a figura do fundador e seu impacto nessas organizações é pouco explorada no meio acadêmico. Assim, esse artigo busca suprir essa lacuna, abordando as influências do fundador na disseminação das estratégias de negócio e de Recursos Humanos (RH) nessas empresas. Através de uma pesquisa de caráter qualitativo e quantitativo, foi realizado um estudo de caso de uma única organização buscando uma análise mais aprofundada do tema. A coleta de dados qualitativa deu-se por meio de uma entrevista com roteiro semiestruturado com o fundador da organização e a qualitativa por meio de aplicação de um questionário com perguntas fechadas com funcionários de diversos níveis hierárquicos. Foi possível observar que os valores e princípios pessoais do fundador estão permeados na organização, refletidos na missão e valores da empresa, assim como a forma como o fundador trata temas como estratégia de negócio e o papel da gestão de pessoas, o que tem sido determinante para a inclusão e condução desses tópicos dentro de organizações de cunho familiar. O objetivo de analisar a disseminação das estratégias de negócio e a de Recursos Humanos pelo Fundador foi alcançado.Constatou-se que, de forma geral, as estratégias retratam a maneira de ser do Fundador, entretanto, a disseminação dessas, para os diversos níveis hierárquicos, demonstra uma complexidade maior, como no caso da GRH.

Investigation of photocatalytic performance of CuS/Bi2WO6 and degradation pathway of RhB in water
Authors: Zhou Houren , Guo Jiaxiu , Fang Ningjie , Liang Juan , Shen Ting , Yuan Shandong
Published: February 2020

A series of CuS/Bi2WO6 composites were synthesized by solvothermal synthesis, which showed enhanced photocatalytic activity. The as-prepared samples were characterized by X-ray diffraction, scanning electron microscopy, high-resolution transmission electron microscopy, photoluminescence ultraviolet–visible absorption spectroscopy, transient photocurrent and EIS. The results showed that as-prepared CuS/Bi2WO6 has flower-like nano microspheres self-assembled by nanoplates and CuS nanorods are uniformly dispersed on its surface. The CuS/Bi2WO6 forms heterojunctions between CuS and Bi2WO6 and shows a wide light response range and a strong light response intensity. The CuS/Bi2WO6 exhibits a better Rhodamine B (RhB) degradation effect than pure Bi2WO6 and CuS, and it can degrade 90% RhB in 50 min and achieve complete degradation in 70 min under Xe lamp irradiation. The CuS/Bi2WO6 has photocatalytic activity in a low pH environment and good stability. The formation of a heterojunction between CuS and Bi2WO6 can effectively separate photo-generated electrons and holes, greatly improving the photocatalytic activity. In the CuS/Bi2WO6-RhB reaction system, O2− is the main active species, and it can rapidly remove the ethyl group from the amino group linked to benzene rings to achieve the N-de-ethylation reaction in the process of RhB degradation. The N-de-ethylated products are simultaneously degraded to small organic molecules and even mineralized into CO2 and H2O.
New stochastic modeling strategy on the prediction enhancement of pier scour depth in cohesive bed materials
Authors: Sharafati Ahmad , Tafarojnoruz Ali , Yaseen Zaher Mundher
Published: February 2020

Scouring around the piers, especially in cohesive bed materials, is a fully stochastic phenomenon and a reliable prediction of scour depth is still a challenging concern for bridge designers. This study introduces a new stochastic model based on the integration of Group Method of Data Handling (GMDH) and Generalized Likelihood Uncertainty Estimation (GLUE) to predict scour depth around piers in cohesive soils. The GLUE approach is developed to estimate the related parameters whereas the GMDH model is used for the prediction target. To assess the adequacy of the GMDH-GLUE model, the conventional GMDH and genetic programming (GP) models are also developed for evaluation. Several statistical performance indicators are computed over both the training and testing phases for the prediction accuracy validation. Based on the attained numerical indicators, the proposed GMDH-GLUE model revealed better predictability performance of pier scour depth against the benchmark models as well as several gathered literature studies. To provide an informative comparison among the proposed techniques (i.e. GMDH-GLUE, GMDH, and GP models), an improvement index () is employed. Results indicated that the GMDH-GLUE model achieved = 6% and = 3%, demonstrating satisfying performance improvement in comparison with the previously proposed GMDH model.

Published: February 2020

Pharmaceutical compounds contribute to the emerging pollutants in water and in many cases, they are not efficiently mineralized by conventional treatment methods. At the same time, landfills remain the main final destination of discarded drugs. In the present study, the mineralization of the Ibuprofen medicinal commercial product (Algofren®) in aqueous solutions using UV irradiation, hydrogen peroxide, titanium dioxide and ferric ions was examined. All experiments were conducted in a batch photoreactor operated for 120–150 min. The main target was to select the most effective operating conditions for the mineralization of the solutions treated. Single photolysis or TiO2 photocatalysis were proved inefficient in eliminating the total organic carbon (TOC). By adjusting the initial amounts of Ibuprofen product and hydrogen peroxide, 81% TOC removal was achieved after 120 min. Adding iron in the solution led to a higher mineralization degree, especially during the first 30 min of the process. Iron was shown also to decrease the environmental footprint of the process as expressed via the electric energy per order, EEo.

Arendt não se dedicou a esmiuçar algumas das nuances históricas das Revoluções Americana e Francesa em sua obra, pois esse não era o seu objetivo, como ela mesma diz em Sobre a revolução. Outrossim, a empreitada da autora era a de se debruçar sobre os desdobramentos e implicações dos eventos em questão. Ela afirmava se interessar pelas questões iminentemente políticas ali postas. Neste artigo, iremos buscar percorrer essa indicativa proposta pela autora. Deste modo, e com a consciência de que o tema gera, ainda, grandes polêmicas, nosso recorte se dá pela perspectiva da relação entre os conceitos de liberdade política e república, tendo como fio condutor os eventos de Sobre a revolução.
Pioneiras da Educação no Brasil: Mulheres, professoras e intelectuais

Published: February 2020

As trajetórias teórico-práticas das intelectuais Nísia Floresta (1810-1885), Ana Maria Saul (1945) e Maria Lacerda de Moura (1887-1945) contribuíram e contribuem para movimentos de reinvenção da Educação nas dimensões popular, epistemológica, cultural, antropológica e política em uma perspectiva histórica. A compreensão de educação e universidade, neste texto, advém da trajetória das professoras que, em suas vidas e obras, possuem significativas contribuições para repensar a universidade na perspectiva da Educação libertadora. A sua prática profissional como mulheres intelectuais e militantes da Educação é permeada por processos de formação política. Entender esse processo na dimensão ético-política colabora no entendimento da Educação como concepção que disputa o projeto de sociedade. O objetivo deste artigo, portanto, é apresentar as trajetórias teórico-práticas dessas mulheres pioneiras da Educação brasileira. O seu trabalho é pouco conhecido pela academia, que por sua vez é machista. Desta maneira, faz-se necessário conhecer como suas trajetórias na educação brasileira possuem significativos impactos nas pesquisas educacionais, trazendo à vista o pensamento dessas mulheres, que é de suma importância para os estudos de educação e mulheres.

Políticas de golpe - sobre o poder de voz e o poder de silenciamento
Authors: Sattler Janyne
Published: February 2020

A proposta deste artigo é refletir sobre os significados engendrados pela voz masculina como a voz do poder por excelência, sinônima de voz pública e de legitimidade política cuja outorga é atribuída em detrimento das vozes femininas ou femininizadas, relegadas ao silêncio da domesticidade. Tais significados são construídos a partir da distinção público-privado-doméstico, oriunda das teorias políticas contratualistas modernas e da imposição social e econômica do capitalismo compreendido como fenômeno de contrarrevolução às lutas sociais anti-feudais. Tais significados reproduzem, sob a luz de uma conceituação aparentemente emancipatória, as imagens de exclusão e silenciamento presentes nos castigos mitológicos impostos sobre mulheres como Io, Eco e Filomela, e que repercutem nas políticas misóginas de texto e de linguagem vivenciadas contemporaneamente por mulheres na política.
Research Advances in the Molecular Functions and Relevant Diseases of TAOKs, Novel STE20 Kinase Family Members
Authors: Ye Junjie , Shi Mingjun , Chen Wei , Zhu Feng , Duan Qiuhong
Published: February 2020

As serine/threonine-protein kinases, Thousand and One Kinases(TAOKs) are members of the GCKlike superfamily, one of two well-known branches of the Ste20 kinase family. Within the last two decades, three functionally similar kinases, namely TAOK1-3, were identified. TAOKs are involved in many molecular and cellular events. Scholars widely believe that TAOKs act as kinases upstream of the MAPK cascade and as factors that interact with MST family kinases, the cytoskeleton, and apoptosis-associated proteins. Therefore, TAOKs are thought to function in tumorigenesis. Additionally, TAOKs participate in signal transduction induced by Notch, TCR, and IL-17. Recent studies found that TAOKs play roles in a series of diseases and conditions, such as the central nervous system dysfunction, herpes viral infection, immune system imbalance, urogenital system malformation during development, cardiovascular events, and childhood obesity. Therefore, inhibitory chemicals targeting TAOKs may be of great significance as potential drugs for these diseases.
Potential Therapeutic Effects of Exogenous Ketone Supplementation for Type 2 Diabetes: A Review
Authors: Walsh Jeremy J. , Myette-Côté Étienne , Neudorf Helena , Little Jonathan P.
Published: February 2020

Type 2 diabetes (T2D) is among the most prevalent non-communicable lifestyle diseases. We propose that overnutrition and low levels of physical activity can contribute to a vicious cycle of hyperglycemia, inflammation and oxidative stress, insulin resistance, and pancreatic β-cell dysfunction. The pathophysiological manifestations of T2D have a particular impact on the vasculature and individuals with T2D are at high risk of cardiovascular disease. Targeting aspects of the vicious cycle represent therapeutic approaches for improving T2D and protecting against cardiovascular complications. The recent advent of exogenous oral ketone supplements represents a novel, non-pharmacological approach to improving T2D pathophysiology and potentially protecting against cardiovascular disease risk. Herein, we review the emerging literature regarding the effects of exogenous ketone supplementation on metabolic control, inflammation, oxidative stress, and cardiovascular function in humans and highlight the potential application for breaking the vicious cycle of T2D pathophysiology.
Control of Oxygen Affinity in Mammalian Hemoglobins: Implications for a System Biology Description of the Respiratory Properties of the Red Blood Cell
Authors: Bellelli Andrea , Brunori Maurizio
Published: February 2020

Hemoglobin and myoglobin have been considered for a long time the paradigmatic model systems for protein function, to the point of being defined the “hydrogen atom[s] of biology”. Given this privileged position and the huge amount of quantitative information available on these proteins, the red blood cell might appear as the model system and“hydrogen atom” of system biology. Indeed, since the red cell's main function is O2 transport by hemoglobin, the gap between the protein and the cell may appear quite small. Yet, a surprisingly large amount of detailed biochemical information is required for the modelization of the respiratory properties of the erythrocyte. This problem is compounded if modelization aims at uncovering or explaining evolutionarily selected functional properties of hemoglobin. The foremost difficulty lies in the fact that hemoglobins having different intrinsic properties and relatively ancient evolutionary divergence may behave similarly in the complex milieu of blood, whereas very similar hemoglobins sharing a substantial sequence similarity may present important functional differences because of the mutation of a few key residues. Thus, the functional properties of hemoglobin and blood may reflect more closely the recent environmental challenges than the remote evolutionary history of the animal. We summarize in this review the case of hemoglobins from mammals, in an attempt to provide a reasoned summary of their complexity that, we hope, may be of help to scientists interested in the quantitative exploration of the evolutionary physiology of respiration. Indeed the basis of a meaningful modelization of the red cell requires a large amount of information collected in painstaking and often forgotten studies of the biochemical properties of hemoglobin carried out over more than a century.
De waarheid, absoluutheid en eigenheid van het christendom volgens Nederlandse protestanten
Authors: Jongeneel J.A.B.
Published: February 2020

This article describes and analyses the views of 20th Dutch Protestant scholars of religious studies, systematic theology and missiology on ‘the absoluteness of Christianity/the revelation of God in Jesus Christ’, and their response to Western relativism rooted in the Enlightenment. Previous adherence to the Augustinian concept of Christianity as ‘the true religion,’ was exchanged for new ideas and positions that took them back to the essentials behind the concept of ‘the absoluteness of Christianity;’ to rethinking ‘absoluteness;’ ‘the non-absoluteness of Christianity;’ and alternative terms such as ‘finality,’ ‘originality,’ and ‘normativity.’ The concept of ‘the absoluteness of Christianity’ may have disappeared but elements thereof survive in new forms.
Tranen in Gods ogen. De keerzijde van het oordeel in het boek Jeremia
Authors: Peels H.G.L.
Published: February 2020

Among the biblical ‘texts of terror’, the prophetic oracles against the nations stand out in their depictions of human and divine violence. Jeremiah’s lengthy oracle of merciless divine judgment against Moab (Jer. 48), centrally focuses on the curse ‘on him who keeps his sword from bloodshed’ (vs 10). Total annihilation leaves Moab without a future (vs 42). More than the other oracles of Jeremiah 46-49, chapter 48 has a theological interest. The prophetic announcement of Moab’s destruction shows an idiosyncratic alternation of judgment and lament, i.e., fierce divine fierce anger and his regret, divine judgment and his wailing over Moab. Detailed analysis shows that YHWH is most likely the subject of weeping several times in Jeremiah 48. This essay seeks to interpret this language of divine grief not figuratively as an ‘ironic inversion of the lamentation’ (Jones), but as a sign of divine compassion (Fretheim). The appearance of God’s tears in the midst of divine violence, inspires the hope that destruction will not have the last word, thereby pointing to a future the New Testament reveals.

Song copyright design has stages of identification, design, manufacture, recording, and feasibility testing. The song creation is expected to be one of the modification of the results of the theme of politeness and make it a habit of modesty.

Ser e como ser... eis a questão: a mudança necessária nos estilos de gestão pública
Authors: González Osorio Héctor Hernán
Published: February 2020

A questão do redesenho do papel do Estado é objeto de importantes discussões sobre as estratégias para sair do subdesenvolvimento. Nessas discussões, uma abordagem mais qualitativa, que subordine os problemas de tamanho à definição de funções, não pode deixar de considerar a forma em que essas funções venham a ser executadas. O como ser é tão importante quanto o ser. Nesse sentido, a questão gerencial, que se manifesta na procura de novos estilos de gestão, marcados pela procura da qualidade e uma prática participativa, constitui uma tendência institucional tão importante quanto as diversas reformas estruturais que buscam reformular o estado brasileiro.
