Authors: Kurniawan Titis , Nurfuadah Irfani , Adiningsih Dian
Published: October 2020

Health beliefs among family members of diabetic patients are important factor of the diabetic preventing behaviours. This study aimed to describe family’s beliefs toward diabetes mellitus prevention based on the Health Belief Model and its’ contributing factors. This corelational study involved 72 peoples that purposively sampled from 34 diabetic patients who live in Jatinangor Public Health Center Working area. A questionnaire developed by the research team consisted of 37 items and 6 domains: perceived susceptibility, severity, benefits, barriers, cues to action, and self efficacy was used to collect the data. The collected data were analyzed descriptively and inferentially. The results showed that most of respondents (77.78%) positively believed on diabetes mellitus (DM) susceptibility, severity (59.72%), benefits of DM prevention (84.77%), and cues to action (76.4%). It was also found that most of respondents negatively believed on the prevention barriers (84%) and self-efficacy (77.78%). Female and actively involved in patient care were found as the contributing factors of the respondents’ beliefs related to DM prevention (p<0.05). To conclude, the DM patients’ family members believed that they are vulnerable to have DM and DM preventions are beneficial. Female and being actively involved in patient care potentially increase the family members’ beliefs toward DM prevention. So, it is important for the healthcare professionals to maximize the family members’ involvement in DM patient care program.

Published: October 2020

Nutritional problems in children are still common, including malnutrition and overweight and obesity. If this problem is not resolved it will have an impact on lack of learning achievement. This study aims to identify the nutritional status of elementary school children and their correlation with learning achievement in mathematics. This cross sectional study used a sample of 56 children in grade 1 elementary school. Nutritional status assessment is based on the Republic of Indonesia's Minister of Health Regulation No. 2 of 2020 concerning Child Anthropometry Standards. Category and threshold (Z score) nutritional status of children based on body mass index according to age (IMT / U) of children aged 5-18 years. Learning achievement is measured by the report card grades for mathematics subjects. Data analysis with Pearson product moment test and Chi-square. The results showed the nutritional status of children; thin: 6 people (10.7%), normal: 37 people (66.1%), fat: 4 people (7.1%) and obese: 9 people (16.1%). The average value of mathematics subjects is 93.16 ± 3.677. There is a relationship between nutritional status and learning achievement in mathematics (p = 0,000). Nutrition problems in children both undernutrition and over nutrition (overweight and obese) need to be addressed so that learning achievement in the future will be optimal.

Authors: Macedo Alline de Alencar , Alves Francisco Régis Vieira , Barroso Maria Cleide da Silva
Published: October 2020

A História e Filosofia da Ciência (HFC) tornou-se um assunto de grande interesse nos últimos anos, pois a interação entre HFC e o ensino ocorre de várias formas, podendo ser como propostas baseadas em diferentes tendências pedagógicas. Porém, o número de trabalhos publicados a respeito da temática HFC no Ensino de Ciências, que relatam resultados de investigações empíricas sobre trabalhos com esse tema apresentando a característica de revisão bibliográfica dividindo a HFC em categorias é inexistente na literatura. Devido à relevância do tema surgiu a necessidade de reunir e organizar os conhecimentos produzidos pelas pesquisas anteriores, percebeu-se a necessidade de fazer um levantamento bibliográfico dos trabalhos que envolvem a referida temática e dividi-las em categorias pela heterogeneidade encontrada diante das leituras, tendo como objetivo trazer um panorama de como a HFC vem sendo estudada. Analisamos um total de 107 artigos publicados entre 2012 e 2017 nas cinco revistas nacionais e uma internacional melhores avaliadas pela CAPES. Os resultados revelaram que das seis categorias que a HFC fora dividida existe um número muito expressivo (metade das categorias) de trabalhos publicados na área da física, como também ficou evidenciado uma escassez e até inexistência de trabalhos na área da Química e Biologia.
Mixing Characteristics Of Gas-Liquid Flow In A Static Mixer: A Numerical Study
Authors: Putra Ryan Anugrah
Published: October 2020

Mixing characteristics of gas-liquid co-current upward flow inside a vertical pipe equipped with a helical static mixer element were numerically investigated. The results from computational fluid dynamics (CFD) simulations with Euler-Euler model of three different length to diameter ratio (L/D) of the static mixer elements were compared. All simulated static mixers provide a better mixing condition in the comparison with the one without a static element. The sudden increase of rotational strength indicated by the liquid velocity curl was observed once the gas-liquid flows enter the static-mixer element zone. The smallest L/D static mixer provides the highest liquid velocity curl in the smallest axial distance providing the most effective mixing process among the tested elements. The best mixing characteristics shown by radial gas distribution was achieved with the static mixer with a smallest L/D.
Beyond Thrombosis: the Role of Platelets in Pulmonary Hypertension
Authors: Nicoleau Salina , Wojciak-Stothard Beata
Published: October 2020

Pulmonary Hypertension (PH) is a multifactorial and lethal disease, characterised by elevated pulmonary arterial pressure and progressive right heart failure. PH pathobiology rests on four pillars: vascular remodelling, vasoconstriction, inflammation and thrombosis. While vascular and inflammatory cells have been the focus of PH research over the past decades, platelets have received relatively less attention, despite their associations with key pathophysiological processes of the disease. Platelets contain a wide range of vasoactive, inflammatory and pro-thrombotic mediators, likely to promote PH development and progression. There is currently no cure for PH, and platelet-associated pathways may help identify new therapeutic strategies. This review summarises available evidence on the role of platelets in different forms of PH, and comments on the current state of platelet-targeting therapies. It also describes the latest advances in the in vitro technologies that enable exploration of platelet function under dynamic and physiologically relevant conditions. Doi: 10.28991/SciMedJ-2020-0204-7 Full Text: PDF
Levin Conjecture for Group Equations of Length 9
Authors: Akram Muhammad Saeed , Amjid Maira , Iqbal Sohail
Published: October 2020

Levin conjecture states that every group equation is solvable over any torsion free group. The conjecture is shown to hold true for group equation of length seven using weight test and curvature distribution method. Recently, these methods are used to show that Levin conjecture is true for some group equations of length eight and nine modulo some exceptional cases. In this paper, we show that Levin conjecture holds true for a group equation of length nine modulo 2 exceptional cases. In addition, we present the list of cases that are still open for two more equations of length nine.

The Component Weighted Median Absolute Deviations Problem
Authors: Novoselac Vedran
Published: October 2020

This paper considers the problem of robust modeling by using the well-known Least Absolute Deviation (LAD) regression. For that purpose, the approximation function is designed and analyzed, which is based on a certain component weight of the Weighted Median of Data. It is shown that the proposed approximation function is a piecewise constant function with finitely many pieces with respect to the model parameter. Thereby, an investigation of regions of constant values of the approximation function is conducted. It is established that the designed model based on the Component Weighted Median Absolute Deviations estimates a optimal model parameter on a finite set, which describes corresponding regions. Furthermore, the specified restriction of the approximation function is observed and analyzed, in order to examine the observed problem.

Authors: Mingxin Zha , Wenxiao Si , Tao Xie
Published: October 2020

It is well known that deviating argument and stochastic disturbance may derail the stability of recurrent neural networks (RNNs). This paper discusses the robustness of global exponential stability (GES) of RNNs accompanied with deviating argument and stochastic disturbance. For a given global exponentially stable RNNs, it is interesting to know how much the length of the interval of piecewise function and the interference intensity so that the disturbed system may still be exponentially stable. The available upper boundary of the range of piecewise variables and the interference intensity in the disturbed RNNs to keep GES are the solutions of some transcendental equations. Finally, some examples are provided to demonstrate the efficacy of the inferential results.

A REVIEW OF RABIES IN LIVESTOCK AND HUMANS IN ETHIOPIA
Authors: Oyda Semayat , Megersa Bekele
Published: October 2020

Rabies, a viral disease caused by lyssa virus of family Rhabdoviridae, is a fatal zoonotic disease with worldwide occurrence and endemic in developing countries of Africa and Asia. Rabies generally affects all warm-blooded animals, but it is primarily a disease of dogs in Ethiopia because access to suspected domestic canids and pets are not controlled indoor or by immunization. The major means of transmission of the disease is through any types of bite, scratch, or other situation in which saliva, cerebral, spinal fluid, tear, or nervous tissues from suspected or known rabid animal or person enters an open wound, is transplanted into, or comes in contact with mucus membrane of another animals or person. One of retrospective study of rabies in Addis Ababa from 1990 – 2000 indicated that an average of 2,200 people per year received post – exposure antirabies treatment while 95% of the reported fatal human rabies case was due to dog bites. The widespread use of traditional medicine among urban and rural population of Ethiopia could be attributed to cultural acceptability, physical accessibility and economic affordability. Individuals who are exposed to the rabies virus often see traditional healers for the diagnosis and treatments of the disease. Once the virus entered into body of exposed individuals through wound (abrasion) or direct contact with mucosal surface, then there, it replicates in the site of deposit (bitten site), where local viral proliferation occurs, and get access (viral attachment) to motor endplates. The clinical sign of the disease is nonspecific and difficult to differentiate without laboratory test, but some of signs such as pupil dilation in some case, paralysis (last stage) and hydrophobia are some characteristic signs. The control of access to domestic canid to other suspected animals is not only prevention method but also is treatment measures. Mass vaccination of dogs and removal of stray canids are the best measure of control. In general, this study provides an overview of the current status of Rabies in livestock and human in Ethiopia.
TO STUDY THE FACTORS THAT IS ENCOURAGING THE CHILD LABOUR IN BARAMULLA DISTRICT OF J&K
Authors: Akhtar Shahida
Published: October 2020

Research into the topic of child labour has experienced a significant upswing in the past two decades. Yet despite this increased attention, child labour remains a significant problem in many parts of the world. According to recent estimates by the International Labor Organization (ILO), there were approximately 176 million children between the ages of 5 and 14 in employment in 2008, of which roughly 53 million were participating in hazardous work (Diallo et al., 2010). A common perception is that most child labourers work for wages in the formal sector, conjuring images of children working long hours in sweatshops or toiling away in mines. As a result, consumer boycotts and trade sanctions against products using child labour as an input are often discussed as means of reducing the incidence of child labour. In reality, however, such methods may have little impact for several reasons. Firstly, the majority of working children are active in the agricultural sector, rather than manufacturing (ILO, 2006; Diallo et al., 2010). Secondly, very few children work for wages outside the home; rather, most children are employed by their parents on the family farm or enterprise (Edmonds and Pavcnik, 2005a).

Published: October 2020

Agriculture has a strategic role in a country whereas food self-sufficiency being the main goal to be achieved. Indonesia has set a strategic plan for increasing the productivity of several commodities, including rice, especially irrigated lowland rice. That matter can be done by agricultural land extensification, which requires a land suitability directional map. This study aims to produce irrigated lowland rice land suitability maps which can be obtained by evaluation using spatial decision tree algorithm. The model is made in two different types, where model Y is an optimized version of model X. The dataset consists of two categories, namely eleven explanatory layers which are land and weather characteristics, and a target layer that represents irrigated lowland rice land suitability in study area of Grobogan Regency, Central Java Province. As an addition to planting requirements, two spatial weather datasets were generated using ordinary cokriging interpolation, which was not used in previous research, while actually being important element for determining plant timing an agricultural commodity. Based on accuracy, model Y is the best model with 96.67%, compared to model X with 86%. Both models make relief variable as the root node, but in spatial decision tree result, model X involves all variables, while model Y does not involve an elevation variable. The addition of weather variables in models is appropriate, as evidenced by the involvement in rules.
The Guggenheim Museum Helsinki Plan as a Media Debate
Authors: Linko Maaria E
Published: October 2020

In connection with today’s competition between cities to portray an alluring image of economic and cultural success, the City of Helsinki and the Solomon R. Guggenheim Foundation put forward a plan to establish a Guggenheim museum in Helsinki, Finland. Following the plan’s release, a heated public debate emerged in the media. The present article analyzes this debate as a mediatized conflict and aims to show in what ways the debate on the Guggenheim report affected the decision-making process concerning the Helsinki Guggenheim museum. This debate is analyzed within the framework of current discussions on the culture-led development of cities, by applying a methodological tool inspired by Luc Boltanski’s and Laurent Thévenot’s theory of critical judgement to analyze the various justifications that the different actors used during the debate. Further, the article interprets why the museum plan was rejected in the first deliberation. It was found that the distance between different actors grew so wide that it could not be reconciled, especially with the effect of social media. Because the City did not encourage a discussion and communication with the art world was neglected at first, during the debate it proved impossible to convince the art world of the benefits a Guggenheim might bring to other art institutions or artists.  Guggenheim Helsinki was planned for a small capital in northern Europe, and yet it is linked to current European politics affected by nationalistic ideology and the question of preserving local cultures in the face of a globally shared culture.  The article ends with a discussion on what can be learned from the failure of the Guggenheim Helsinki.
Displaying Values, Scripting Stories: Writing Narratives of Environment Citizenship through Permanent Educational Exhibits at Local Nature Preserves
Authors: Johns Rebecca Anne , Pontes Rachelle
Published: October 2020

Material and interactive exhibits are important elements of many sites of learning, including science, technology, history and natural history museums. Parks and nature preserves are not usually identified as museums, and their purpose and mission do not necessarily align with the mission focus of museums. We argue here, however, that permanent environmental education exhibits at preserves should be treated as museums for analytic purposes. Preserve displays typically include collections of objects from within the park’s boundaries, i.e., bones, shells, rocks, skeletons, feathers, pelts, cones, etc., in addition to manufactured displays presenting ecosystems and physical as well as living elements of the environment. Exhibits at preserves have not been the focus of scholarship on museums to date. Bringing together analytic tools developed for museum experiences with evaluative frameworks from the field of environmental education provides a rich set of concepts for understanding the work that nature preserve exhibits do to increase ecoliteracy. We analyze permanent and interactive educational exhibits at three nature preserves in Florida through the application of a series of interdisciplinary and overlapping frameworks. We identify opportunities for transmission of knowledge about the environment and human interactions with local landscapes; opportunities for cognitive engagement with material artefacts and for participation in knowledge construction. We identify messages that use emotional engagement to encourage visitors to become active citizens on behalf of nature and humans; and to ultimately engage in sustainable actions to solve environmental problems.

Authors: Deng Dongyang , Lin Lian-shin , Ofori-Boadu Andrea Nana
Published: October 2020

This study investigated coal-mine drainage (AMD) and municipal wastewater (MWW) contaminant concentrations and conducted the combined treatment in phases I and II: phase I, evaluating effects of mixing the two based on extent of acid neutralization and metals removal; phase II: conducting anaerobic batch reactor treatment of AMD and MWW under varying COD/sulfate ratios (0.04-5.0). In phase I, acid mine drainage water quality conditions are as follows: pH 4.5, acidity 467.5 mg/L as CaCO3, alkalinity 96.0 mg/L as CaCO3, Cl- 11.8 mg/L, SO42- 1722 mg/L, TDS 2757.5 mg/L, TSS 9.8 mg/L, BOD 14.7 mg/L, Fe 138.1 mg/L, Mg 110.8 mg/L. Mn 7.5 mg/L, Al 8.1 mg/L, Na 114.2 mg/L, and Ca 233.5 mg/L. Results of the mixing experiments indicated significant removal of selected metals (Fe 85~98%, Mg 0~65%, Mn 63~89%, Al 98~99%, Na 0~30%), acidity (77~95%) from the mine water and pH was raised to above 6.3. The Phase II results suggested under the wide range of COD/sulfate ratios, COD and sulfate removal varied from 37.4%-100% and 0%-93.5% respectively. During biological treatment, alkalinity was generated which leads to pH increase to around 7.6-8.5. The results suggested feasibility of the proposed technology for co-treatment of AMD and MWW. A conceptual design of co-treatment system which is expected to remove a matrix of pollutants has been provided to utilize all the locally available water resources to achieve the optimum treatment efficiency. The technology also offers an opportunity to significantly reduce capital and operating costs compared to the existing treatment methodologies used.
Impacts of Foreign Direct Investment on Economic Growth in the East African Community (EAC): Empirical Evidence from Burundi
Authors: Irakoze Eric , YU Baorong
Published: October 2020

This study analyzes how Foreign Direct Investment affects the rate of economic development among nations in the EAC with the empirical evidence of Burundi. The paper indicates that there is a link between foreign direct investment(FDI), gross domestic product(GDP), human capital, and openness with support of yearly time-series data from 1989 to 2017. The results from the Vector Error Correction Model (VECM) analysis technics discover that all the variables in long-term they move together. The findings also discovered that there is short-term causality running from GDP and human capital to FDI and no short-run causality found from openness to FDI as a result of Burundi’s policies that do not implement market seeker FDI. For VECM validation, the paper went through some post estimation diagnostic tests such as Lagrange multiplier tests and Jarque-Bera test, the results did not indicate any autocorrelation among the variables as the residuals were normally distributed. Openness being an important factor to attracting foreign investors, it is very crucial for Burundi to revise its trade policies and encourage a conducive environment that promotes foreign investment penetration by promoting and encouraging both domestic and foreign investors and keep improving human capital for more FDI attraction as a goal for Burundi economic growth.
Option Pricing beyond Black-Scholes Model: Quantum Mechanics Approach
Authors: Li Pengpeng , Liang Shidong
Published: October 2020

Based on the analog between the stochastic dynamics and quantum harmonic oscillator, we propose a market force driving model to generalize the Black-Scholes model in ﬁnance market. We give new schemes of option pricing, in which we can take various unexpected market behaviors into account to modify the option pricing. As examples, we present several market forces to analyze their eﬀects on the option pricing. These results provide us two practical applications. One is to be used as a new scheme of option pricing when we can predict some hidden market forces or behaviors emerging. The other implies the existence of some risk premium when some unexpected forces emerge.

Cascade reservoirs optimal operation through combined guide curves
Authors: A.D. Ampitiyawatta
Published: October 2020

This study is concerned with the optimal operation of cascade reservoir system for hydropower generation. The problem involves optimizing hydropower production while reducing excess water spill during the flood season. A new combined reservoir operation model is proposed based on combined guide curves for optimizing hydropower production and for better storage distribution among cascade reservoirs. The storage distribution among cascade reservoirs is achieved by the storage effectiveness index method. The model is optimized with the particle swarm optimization algorithm and applied to the Qingjiang River cascade reservoir system in China. The optimized combined guide curves for Shuibuya-Geheyan reservoirs are obtained and compared with conventional reservoir operation charts and Lund analytical solution method. Simulation results show that the proposed model can modulate water levels of the Shuibuya reservoir and effectively increase hydropower heads of the Geheyan reservoir. Comparing with the original design, the proposed model enhances hydropower production considerably while reducing the spill release. It is capable to produce an extra amount of 201 GWh electrical energy (a 2.77% increment) and save 1067 Mm3 of flood water resources (a 38.96% reduction) annually in the Qingjiang cascade reservoirs.

Published: October 2020

Diagnosis and management of emerging infections like COVID 19 is a combination of clinical, epidemiological, and laboratory considerations. The mainstay of diagnosis is RT-PCR from oro-nasal swabs. Other blood investigations for hematology and biochemistry and imaging for chest infections can be supportive and may have prognostic value. Clinical management mainly involves supportive care as any acute care lung infections and sepsis, oxygen therapy, either invasive or non-invasive, as applicable. Corticosteroid therapy and anticoagulation are known to somewhat effective. Ivermectin, Tocilizumab, Favipiravir, and Remdesivir have shown to be of some benefit. Convalescent plasma therapy has been tried with not much evidence of benefit. Conclusive evidence for any particular modality of treatment is yet to be published. It is pertinent to understand that the successful management of critically ill patients with multi-system involvement requires a concerted holistic approach with multidisciplinary care.

Irrigated agriculture is dependent on an adequate water supply of usable quality. The different Irrigation sites were identified randomly, and named A, B, C, D and E respectively. Therefore, water and sediment or soil samples were collected from Rukuba Road River, Yelwan Zangam River, Gangare River, Busa Buji River and Angwan Rimi River respectively in Jos, Plateau State, Nigeria to evaluate their salinity level suitability for irrigation purpose and Agricultural Farming. The analytical results shows that the Electrical conductivity (EWc), Total dissolve solids (TDS), Sodium adsorption ratio (SAR) and specific ion toxicities of water and sediment are as followed: Rukuba Road River “A” (ECw = 508.00 µs/cm, 897.00µs/cm; TDS = 440.50 mg/l, 540.60mg/l and SAR = 12.73, ND), Yalwan Zangam River “B” ( ECw = 750.00µs/cm, 987.00µs/cm; TDS = 330.20mg/l, 470.50mg/l and SAR = 12.56, ND), Gangare River “C” (ECw = 489.00µs/cm, 897.00µs/cm; TDS = 40.70mg/l, 550.90mg/l and SAR = 13.16, ND), Busa Buji River “D” (ECw = 250.00µs/cm, 499.00µS/cm; TDS = 355.60mg/l, 495.00mg/l and SAR = 14.06, ND) and Angwan Rimi River “E” (ECw = 1030.00µs/cm, 1233.00µs/cm; TDS = 460.00mg/l, 610.60mg/l and SAR = 11.20, ND). The salinity of river A B C D fall within the normal ranges which were of excellent quality and considered to be highly suitable without any restriction on the use. Water and sediment from Angwan River “E” (ECw = 1030.00µs/cm, 1233.00µs/cm; TDS = 460.00mg/l, 610.60mg/l and SAR = 19.20, ND) will be highly suitable under proper management such as improved irrigation system and schedule, light soil with good infiltration and internal drainage and plant with good salt tolerant. The variation in chemical composition of the irrigation water and sediment sources could be attributed to the fact that the Angwan Rimi River “E” water and sediment sources are located within Jos metropolis. The additions from waste waters (domestic sewage and municipal), dirt and suspended inorganic matter and automobile effluents from Mechanic workshops could contributes to the high levels of Salinity, SAR and Total hardness and specific ion toxicities of the irrigation water.

Punica granatum L. (Pomegranate) is utilized in the treatment of parasitic contamination, loose bowels and ulcers. Extracts of the various parts of P. granum is reported to have anti-inflammatory, antioxidant and anticarcinogenic activities. Tannins are a group of polyphenolic compounds that are widely present in plant regions and possess various biological activities including antimicrobial, anti-parasitic, anti-viral, antioxidant, anti-inflammatory, immunomodulatory activities. This study focused on extraction of tannins from Punica granatum peel which can be further analyzed for its pharmacological activities. The results of this study revealed the abundance of tannins in the pomegranate peel extract. Tannins from pomegranate peel might contribute to the high antioxidant activity of this fruit peel and it is a valuable natural antioxidant source applicable in the health food industry.

Molecular docking is a computational technique that places a small molecule (ligand) in the binding site of its macromolecular target (receptor) and estimates its binding affinity. The present study attempted the high throughput in-silico screening of 65 compounds docked with the GABAA receptor (PDB ID: 4COF) using Molegro virtual docker (6.0). Out of these 65 compounds, 17 compounds showed very good mol dock score in ranging between -66.344 & -102.653. Ethosuximide and Carbamazepine drugs was used as a standard drug which showed mol dock score -50.6357 & -58.5047 respectively. Most of test compounds demonstrated excellent number of hydrogen bond interactions viz compounds 33, 38, 39, 45, 47, 53, 54, 59, 61, 62, 63, 64 & 65 which showed 7 to 11 number of hydrogen bond interactions as compared to standard drug interactions values 6 & 5 respectively and also showed the interaction with same amino acids Glu52, Ser51and Val53 and some other amino acids Asn54, Thr58 and Thr133 also showed very acceptable bond length less than 3.91Å. The obtained results indicated that all studied ligands have similar position and orientation inside the putative binding site of GABAA receptor (PDB ID: 4COF) which reveals a large space bounded by a membrane-binding domain which serves as an entry channel for substrate to the active site. In addition, the affinity of any small molecule can be considered as a unique tool in the field of drug design and offer prospective in future research to develop a potent anticonvulsant agent.

Prematurity is one of the main causes of neonatal morbidity and mortality and is responsible for a high percentage of infant sequelae, especially in very early gestation ages. Every year an estimated 15 million children are born preterm and this number continues to increase. Approximately 1 million children die each year as a result of the complications of preterm birth. We decide to perform a descriptive and retrospective study of patients admitted to Ángel Arturo Aballí Maternal-Infant Hospital, during the period from July to December 2015. 102 patients who were admitted in this center with symptoms of threatened preterm birth, single fetus and intact membranes. The birth and medical records of mothers and newborns were reviewed, as well the statistics department. For the processing and analysis, the SPSS statistical program was used and the results were expressed in numbers and percentages. Results showed that the average age of the mothers was between 20-25 years, the gestational age between 30-34 weeks, the most frequent cervical modification was the shortening of the cervix and most of the patients were managed to reach 37 weeks gestation. It was concluded that transvaginal ultrasound increases the sensitivity and specificity for the diagnosis of preterm delivery and also the shorter of the cervix increase the risk of preterm delivery.

NOTAS SOBRE A RELAÇÃO ENTRE DIALÉTICA E HISTÓRIA NA RECEPÇÃO DE HEGEL POR MARX
Authors: Schäfer Márcio Egídio
Published: October 2020

Uma parte considerável do pensamento de Marx foi moldada no contexto de sua confrontação crítica com a filosofia de Hegel. O presente trabalho pretende reconstruir esse confronto crítico abordando dois aspectos específicos: a dialética e a história. Procurar-se-á mostrar que Marx interessa-se, em distintas fases de sua produção, por aspectos distintos da dialética hegeliana. Ao ocupar-se com aspectos específicos da dialética de Hegel, Marx igualmente desenvolve concepções distintas de história. Com isso sugere-se, igualmente, que há uma relação intrínseca entre as concepções de história de Marx e as concepções específicas de dialética por ele tematizadas nos diferentes períodos de sua produção teórica.
A CATEGORIA DO SEM-MEDIDA EM HEGEL E MARX
Authors: Orsini Federico
Published: October 2020

O objetivo deste artigo é analisar as transformações que a categoria de “sem-medida” (maßlos) experimenta na transição da Ciência da Lógica de Hegel para O Capital de Marx. A premissa metodológica de minha investigação é a ideia de que exigência de esclarecer o método de O Capital traz consigo a necessidade de uma análise comparativa com o método hegeliano. A análise contém duas partes. Na primeira parte, mostrarei como o sem-medida surge nos primeiros capítulos de O Capital. Na segunda parte, reconstituirei a categoria de sem-medida na Doutrina do Ser (1832) de Hegel. Nas considerações conclusivas, apontarei três semelhanças e três diferenças entre as duas figuras do sem- medida em Hegel e em Marx. As semelhanças são: o uso de uma lógica dialética, a interação do qualitativo e do quantitativo, e o princípio da explicitação da coisa mesma. As diferenças dependem da diferença entre uma lógica sem-pressupostos e uma lógica peculiar do objeto peculiar.
SUBSTANTIELLE FREIHEIT ODER REELLE SUBSUMTION PROBLEME DER SITTLICHEN VERMITTLUNG BÜRGERLICHER GESELLSCHAFTEN
Authors: Städtler Michael
Published: October 2020

Hegels Begriff der Sittlichkeit steht für substantielle Freiheit, insofern er gleichermaßen die moralischen Prinzipien der Gesellschaft und ihre Verwirklichungsbedingungen umfasst. Deshalb wird er häufig als Korrektiv sozialer Pathologien bemüht. Der objektive Geist, die rechtlich organisierte Gesellschaft, ist aber prinzipiell in sich widersprüchlich verfasst. In diesen Widersprüchen machen sich herrschaftliche Elemente im Geistbegriff geltend, die sich auch in den heute sozialphilosophisch beliebten Konzepten von Anerkennung und Sittlichkeit auswirken. Die spezifisch gesellschaftliche Herrschaft, die mit den moralischen Prinzipien im Sittlichkeitsbegriff unvereinbar ist, wird von Hegel nicht ausreichend reflektiert. Marx gelingt es, mit dem Konzept der reellen Subsumtion der Arbeit unter das Kapital eine systematische Erklärung der spezifischen, institutionell vermittelten Herrschaft in der bürgerlichen Gesellschaft zu geben. Damit erweisen sich aber bürgerlich-kapitalistische Gesellschaft und Sittlichkeit als unvereinbar.
