Authors: Ardi Syahril , Fairus Sirin , Sukmaningrum Sekar
Published: April 2020

Wastewater Treatment Plant (WWTP) is one of the infrastructures and systems in the manufacturing industry. This system serves to treat wastewater coming from boiler machines, which are used to produce steam to support the tire and tube production process of manufacturing companies, which are the object of our research. Wastewater from this boiler machine is alkaline and contains solids that are harmful to the ecosystem and the environment, so it needs to be processed so that wastewater can be discharged into drains. The process is not by following the standards; it can affect the quality of the process water so that water that is discharged into drains or water bodies violates government regulations. In this case, the pH standard of water is in a neutral state whose values are between 6 and 9 and is clear in color. Therefore, we conducted research that is designing a system to control and monitor the process at the wastewater treatment plant automatically. The design of this control system is done by adding sensors and actuators that are connected to the modular PLC that is the control system. This system is also designed to be connected to a PC (Personal Computer) as a monitoring system so that the process can be monitored continuously. Display interface created using HMI (Human Machine Interface) software. This is because many features that allow for a more attractive appearance. With this system, it can be sure that the boiler wastewater treatment process is more consistent and efficient in maintaining pH standards, and the process is monitored in real-time.

Published: April 2020

In presence of hydrodynamics phenomena occur surrounding propeller evidently affects on accuracy’s prediction of thrust, torque and its efficiency. To achieve the objective, a Computational Fluid Dynamics (CFD) simulations approach is then proposed to obtain a reliable prediction of the thrust (KT), torque (KQ) and efficiency (η) coefficients in open water condition. The effect of various blade numbers associated with constant propeller revolution (RPM=1320) and pitch ratio (P/D=1.0); are performed within the range of advance ratio from 0.1J1.0. The results revealed that the increase of blade number from Z=3 to 5 was proportional with the increase of thrust (KT) and torque (KQ) coefficients; meanwhile, it was reduced the maximum efficiency (η) that possibly lead to downgrade the propeller performance. It should be noted here, the propeller with three blade numbers (Z=3) provide the highest efficiency (η) up to 78.8% at J=0.9. These CFD simulation results are very useful as a preliminary study of propeller characteristics.

Published: April 2020

O valor atribuído às expressões atividade física ou práticas corporais guarda estreita relação com o referencial epistêmico que possuem acerca do corpo, incidindo sobre a própria Educação Física (sua especificidade). Considerando as implicações que o corpo gera para a Educação Física, exploramos neste ensaio a noção de corpo no pragmatismo de Richard Rorty (1931-2007). O objetivo é compreender a perspectiva rortyano-pragmática de corpo e suas implicações para a Educação Física. Dentre outros aspectos, nossa leitura sugere compreender o corpo como contingente e não admitindo fins teleológicos, deixando em aberto para exploração e redescrições. A implicação para a Educação Física é a ênfase nos critérios sociais e políticos (e não epistemológicos e ontológicos) para a criação de ações e pensamentos mais profícuos para a realização da educação corporal.
A model based new method for injection rate determination
Authors: Vass Sandor , Zoldy Mate
Published: April 2020

This paper presents a detailed model of a common rail diesel injector and its validation using injection rate measurement. A new method is described for injector nozzle flowrate determination using simulation and measurement tools. The injector model contains fluid dynamic, mechanic and electro-magnetic systems, describing all-important internal processes and also includes the injection rate meter model. Injection rate measurements were made using the Bosch method, based on recording the pressure traces in a length of fuel during injections. Comparing the results of the simulated injection rate meter, simulated injector orifice flow and injection rate measurements, the simulated and measured injection rates showed good conformity. In addition to this, the difference between nozzle flow rate and the measured flow rate is pointed out in different operating points, proving, that the results of a Bosch type injection rate measurements cannot be directly used for model validation. However, combining injector, injection rate meter simulation and measurement data, the accurate nozzle flow rate can be determined, and the model validated.

Authors: Guan Zixu , Cui Yi
Published: April 2020

Aiming at the thermal load problem of the four-stroke high-speed Diesel engine piston, a piston thermal fluid-solid coupling model based on the combustion thermal boundary and the two-phase flow oscillation cooling thermal boundary is established. The model considers the problem that the piston cannot fill the cooling cavity due to the reciprocating motion. The effects of different engine speeds and the injection speed on the filling rate are studied. The variation curves of the filling rate of the oil in the cooling cavity are simulated, and the transient heat transfer coefficient and temperature of each crank angle are obtained. The average value is then analyzed by thermal flow-solid coupling method, and the influence of the filling rate of the piston cavity on the temperature field of the piston is obtained. Through the comparison of the experimental results of the hardness plug measurement method, the calculation of the model is accurate and can be well used for the simulation of the piston temperature field and the evaluation of the thermal load at the critical position. Based on this model, the regularity analysis of the influencing factors of the piston thermal load is carried out. The influencing factors include the filling rate of the cavity, the air-fuel ratio, the injection timing, etc., and finally the engine operating range that meets the heat load requirements is obtained.

Authors: Sekulic Dragan , Ivkovic Ivan , Mladenovic Dusan , Vujanovic Davor
Published: April 2020

This paper analyzes the effects of intercity bus suspension system oscillatory parameters on driver?s ride comfort and road damage. The analysis has been carried out through simulation by means of validated in-plane bus model with six degrees of freedom ex-cited by real road roughness signal. Low root-mean-square values of the weighted vertical acceleration (less than 0.315 m/s2) have been achieved by shock-absorbers with lower damping coefficient and softer suspension system springs. Low values of dynamic load coefficient provide low shock-absorber damping and softer springs. However, low crest factor values for both axles are accomplished for high shock-absorber damping and softer springs in bus suspension system. Results from this analysis could be used as reference for selecting proper oscillatory parameter values when designing road-friendly bus suspension system which in turn would increase vehicle energy efficiency. Presented methods, results and analyzes are the part of wider methodology for assessing the impact of bus suspension system on fuel consumption and CO2 emission.

Authors: Sun Xudong , Xu Xiaoming , Tang Wei , Jin Huifen , Ding Hua
Published: April 2020

High speed rail vehicles need to start the emergency traction battery system in an emergency. In order to ensure that the emergency traction battery system can be quickly started in cold conditions and ensure that the high speed railway has sufficient mileage, this paper proposes a multi-stage heating method based on flat heat pipes. The thermodynamic parameters of the power battery are obtained by simulation analysis and experimental verification. According to the thermodynamic model, the heat generation model and coupled heat transfer model of the battery are established. Different heating powers are assigned to different heating points and the total heating power is kept constant. Through the analysis results, the multi-stage heating device of the emergency traction battery system can effectively reduce the heating time under cold conditions and the temperature difference between the battery system Modules. This paper can provide reference to the design of the battery pack and the matching of the heating system.
Applying the econometric modelling on the monitoring of wood energy consumption in households: Case study southwestern Serbia
Authors: Glavonjic Branko , Palus Hubert , Lazarevic Aleksandra
Published: April 2020

This paper focuses on two main research topics: the situation in the field of wood energy efficiency utilization in households in the region of Southwestern Serbia, and econometric modelling of wood energy consumption dependent on the size of the heating surface, the existence of thermal insulation on residential buildings, the age of heating appliances and moisture content of wood fuels. The results of the conducted research showed that the consumption of wood energy in most household?s ranges between 300 and 400 kWh/m2. This is considered energy inefficient. Although in the majority of households the size of the heating surface ranges between just 20 and 80 m2, exactly in these households the highest and the most inefficient consumption of wood energy expressed in kWh/m2 was registered. The first reason for the high consumption of wood energy is the fact that only 29% of residential buildings have thermal insulation, while 71% do not have any thermal insulation. Additionally, the wide diffusion of heating appliances aging over ten years and firewood with the average moisture content of 37% further contribute to such unfavourable situation in terms of energy efficiency. The parameters of the obtained econometric model of wood energy consumption clearly show that the greatest savings in the consumption of wood energy in the short term could be obtained by improving the condition of the thermal insulation of the residential buildings, replacing the old heating appliances with the new and the more efficient ones, as well as by using drier firewood.

Published: April 2020

Previous studies showed that 12 weeks of high-fat diet (HFD) consumption caused not only prediabetes but also cognitive decline and brain pathologies. Recently, necrostatin-1 (nec-1), a necroptosis inhibitor, showed beneficial effects in brain against stroke. However, the comparative effects of nec-1 and metformin on cognition and brain pathologies in prediabetes have not been investigated. We hypothesized that nec-1 and metformin equally attenuated cognitive decline and brain pathologies in prediabetic rats. Rats (n = 32) were fed with either normal diet (ND) or HFD for 20 weeks. At week 13, ND-fed rats were given a vehicle (n = 8) and HFD-fed rats were randomly assigned into three subgroups (n = 8/subgroup) with vehicle, nec-1, or metformin for 8 weeks. Metabolic parameters, cognitive function, brain insulin receptor function, synaptic plasticity, dendritic spine density, microglial morphology, brain mitochondrial function, Alzheimer protein, and cell death were determined. HFD-fed rats exhibited prediabetes, cognitive decline, and brain pathologies. Nec-1 and metformin equally improved cognitive function, synaptic plasticity, dendritic spine density, microglial morphology, and brain mitochondrial function and reduced hyperphosphorylated Tau and necroptosis in HFD-fed rats. Interestingly, metformin, but not nec-1, improved brain insulin sensitivity in those rats. In conclusion, necroptosis inhibition directly improved cognition in prediabetic rats without alteration in insulin sensitivity.

Published: April 2020

OBJECTIVE

Type 2 diabetes develops for many years before diagnosis. We aimed to reveal early metabolic features characterizing liability to adult disease by examining genetic liability to adult type 2 diabetes in relation to metabolomic traits across early life.

RESEARCH DESIGN AND METHODS

Up to 4,761 offspring from the Avon Longitudinal Study of Parents and Children were studied. Linear models were used to examine effects of a genetic risk score (162 variants) for adult type 2 diabetes on 229 metabolomic traits (lipoprotein subclass–specific cholesterol and triglycerides, amino acids, glycoprotein acetyls, and others) measured at age 8 years, 16 years, 18 years, and 25 years. Two-sample Mendelian randomization (MR) was also conducted using genome-wide association study data on metabolomic traits in an independent sample of 24,925 adults.

RESULTS

At age 8 years, associations were most evident for type 2 diabetes liability (per SD higher) with lower lipids in HDL subtypes (e.g., −0.03 SD [95% CI −0.06, −0.003] for total lipids in very large HDL). At 16 years, associations were stronger with preglycemic traits, including citrate and with glycoprotein acetyls (0.05 SD; 95% CI 0.01, 0.08), and at 18 years, associations were stronger with branched-chain amino acids. At 25 years, associations had strengthened with VLDL lipids and remained consistent with previously altered traits, including HDL lipids. Two-sample MR estimates among adults indicated persistent patterns of effect of disease liability.

CONCLUSIONS

Our results support perturbed HDL lipid metabolism as one of the earliest features of type 2 diabetes liability, alongside higher branched-chain amino acid and inflammatory levels. Several features are apparent in childhood as early as age 8 years, decades before the clinical onset of disease.
Influence of welding parameters on electromagnetic supported degassing of die-casted and wrought aluminum
Authors: Fritzsche André , Hilgenberg Kai , Rethmeier Michael
Published: April 2020

Laser beam welding of aluminum die casting is challenging. A large quantity of gases (in particular, hydrogen) is absorbed by aluminum during the die-cast manufacturing process and is contained in the base material in solved or bound form. After remelting by the laser, the gases are released and are present in the melt as pores. Many of these metallurgic pores remain in the weld seam as a result of the high solidification velocities. The natural (Archimedean) buoyancy is not sufficient to remove the pores from the weld pool, leading to process instabilities and poor mechanical properties of the weld. Therefore, an electromagnetic (EM) system is used to apply an additional buoyancy component to the pores. The physical mechanism is based on the generation of Lorentz forces, whereby an electromagnetic pressure is introduced into the weld pool. The EM system exploits the difference in electrical conductivity between poorly conducting pores (inclusions) and the comparatively better conducting aluminum melt to increase the resulting buoyancy velocity of the pores. Within the present study, the electromagnetic supported degassing is investigated in dependence on the laser beam power, welding velocity, and electromagnetic flux density. By means of a design of experiments, a systematic variation of these parameters is carried out for partial penetration laser beam welding of 6 mm thick sheets of wrought aluminum alloy AlMg3 and die-cast aluminum alloy AlSi12(Fe), where the wrought alloy serves as a reference. The proportion of pores in the weld seams is determined using x-ray images, computed tomography images, and cross-sectional images. The results prove a significant reduction of the porosity up to 70% for both materials as a function of the magnetic flux density.
Normal vector distribution as a classification tool for convoluted rough surfaces with overhanging features
Authors: Olsson R. , Powell J. , Frostevarg J. , Kaplan A. F. H.
Published: April 2020

Convoluted rough surfaces involving overhanging features can be a natural consequence of laser additive manufacturing and other spray techniques or can be generated deliberately by laser surface texturing, e.g., to aid osseointegration. Overhanging features add an extra level of complexity to the topography of a rough surface and can have a substantial effect on wettability, etc. However, features of this type are invisible to traditional surface roughness measurement techniques. This work presents a computer-based surface analysis method that gives useful information about the presence and nature of overhanging features on rough technical surfaces. The technique uses micro-computer tomography to generate a typical cross section of the surface under investigation. The angles of the vectors normal to the surface can then be analyzed to reveal the presence of overhanging features, which can also be indicated by the standard deviation of the normal vector distribution. Titanium surfaces generated by six different techniques were compared. The characteristics of these surfaces varied strongly, as did the shapes of the overhangs involved. These variations are reflected by different statistical distributions of the normal vectors.
Laser power modulation to grain refinement of SAE 1045 steel welds
Authors: Neto Francisco Cavilha , Fredel Marcio Celso , Pereira Milton , Paes Luiz Eduardo dos Santos
Published: April 2020

Refined grain size structure is one of the most sought-after features during parameterization of welding processing. Refined grains in the region of the molten zone provide high tenacity in addition to high hardness, due to the dislocation blocking by grain boundaries. However, obtaining refined grain structure is not trivial, since a molten pool is formed during bonding of materials via welding, which often results in grain growth. In this sense, this study aimed to refine the granular structure of an SAE 1045 steel by modulating laser power. The success through the modulation method in some aspects of welding is well known from the literature, such as the reduction of pores and cracks as well as deep penetration with narrow heat affected zones. These enhancements are due to cooling rate control produced by the nonuniform way of interaction between the laser and the specimen. In the present study, 1045 steel specimens were first welded utilizing the conventional continuous mode and then the results were compared with a modulated rectangular-shaped power mode while maintaining the average power constant. Microhardness measurements were used in order to investigate the mechanical effect of grain size changes. It was found that an increase in hardness of 50 HV was achieved by modulating the laser power in time. This increase is credited to the reduction in grain size of the studied steel. It can be assumed that the time modulation of the laser power provides a better control of the cooling rate and consequently the mass flux in the molten pool, what may explain the hardening effect by grain refinement.

Published: April 2020

In wireless sensor networks, the clustering method is often used to transmit information, which is one of the most energy efficient approaches. Since the master cluster node interacts with other nodes in the network, a node with a high residual energy is selected to perform its functions. The technology of selecting the main node based on fuzzy logic, which involves the use of a number of input parameters, the effect of which is demonstrated in the article, is proposed.

Islam dalam Budaya Jawa Perspektif Al-Qurâ€™an
Authors: Umar Mohamad Toha
Published: April 2020

The purpose of this study is to unfold the relations between culture and Islam in the Qurâ€™anic perspective. This paper examines the traditions that are absorbed into the aesthetic values of Islam, namely Sedekah Laut (sea offerings) and Wayang (shadow puppet). The data were collected through observations and library studies to find out the perspective of the Quran in viewing culture and tradition. The results of this study indicated that the Quran provides spaces for humans to constantly do ijtihad (seeking) that tradition and culture (â€˜urf) can be positioned as a source of Islamic law (fiqh). In the meantime, the rule of ushul fiqh for this case is â€œall cases are basically permitted until an argument comes to forbid them.â€ The results of this study showed that the Javanese traditions and culture, especially Sedekah Laut and Wayang, contained the values of Aqidah (faith), Muamalah (social values), and Akhlaqul Karimah (morals). In the Aqidah value, Wayang and Sedekah Laut are positioned as symbols of obedience and gratitude to Allah SWT. In the Muamalah value, tradition can evoke the strength of the community in various fields, for example, social and economy because both traditions, especially the sea offering are able to attract people. Meanwhile, the Akhlaqul Karimah value of the sea offering is that it represents the relationship between humans and nature, while the puppet is that it becomes disposition symbols aimed at Allah SWT.

 

Tujuan penelitian ini untuk mengungkap hubungan antara budaya dan Islam dalam perspektif al-Qurâ€™an. Tulisan ini mengkaji tradisi yang diserap ke dalam nilai estetika Islam, yakni sedekah laut dan wayang. Data dalam tulisan ini berdasarkan observasi dan data kepustakaan untuk mengetahui perspektif al-Qurâ€™an dalam memandang budaya dan tradisi. Hasil penelitian ini menunjukkan bahwa Al-Qurâ€™an memberikan ruang bagi manusia untuk senantiasa berijtihad bahwa tradisi dan budaya (â€™urf) dapat diposisikan sebagai sumber hukum (fiqh) Islam. Dalam pada itu, kaidah ushul fiqhnya adalah â€œpada mulanya semua perkara diperbolehkan, sebelum ada dalil yang mengharamkannya.â€ Hasil kajian ini menunjukkan bahwa dalam tradisi dan budaya (Jawa), khususnya wayang dan sedekah laut terdapat nilai aqidah, muamalah dan akhlaqul karimah. Dalam nilai aqidah, wayang dan sedekah laut diposisikan sebagai simbol ketaatan dan rasa syukur kepada Allah SWT. Dalam nilai muamalah, tradisi tersebut dapat membangkitkan kekuatan publik (kelompok) dalam berbagai bidang, misalnya sosial dan ekonomi karena kedua tradisi itu, khususnya sedekah laut mampu mengundang animo massa. Nilai akhlaqul karimah dalam sedekah laut merupakan representasi dari hubungan esoterik manusia dengan alam, sedangkan dalam wayang menjadi simbol perwatakan yang mengarah kepada Allah SWT.

Los derechos sociales como derechos «de segunda»: razones frecuentes y visiones críticas
Authors: Nasif Santiago Andrés
Published: April 2020

En este artículo indago sobre la exigibilidad de los derechos sociales a partir de visiones críticas que formulan autores que entienden a la democracia como una conversación entre iguales (Habermas, Nino, Gargarella, Alegre, Atria). Particularmente, examino algunas razones que han contribuido a reducirlos a «derechos de segunda», frente a los civiles y políticos. En ese cometido evalúo dos categorías de frecuente uso en el discurso de los derechos humanos: la que los califica según sean (o no) operativos y la que los separa por generaciones. A partir de allí doy cuenta de la convergencia existente entre las categorías «derechos de segunda generación» y «derechos programáticos». Luego describo visiones críticas de esa reducción, para sugerir que garantizar derechos sociales puede mejorar el valor sustantivo y el valor epistémico de los procesos democráticos. Finalmente, apunto algunas reflexiones provisorias.

El derecho en la obra de Michel Foucault. Un desajuste entre prácticas y conceptualizaciones
Authors: Benente Mauro
Published: April 2020

Si bien los trabajos de Michel Foucault han tenido influencia en numerosas disciplinas, no abundan los estudios que tematicen sobre sus aportes al derecho. Durante quince años, las discusiones sobre la ley en la obra de Foucault giraron en apoyo o en respuesta a los desarrollos de Foucault and Law publicado por Alan Hunt y Gary Wickham en 1994. Con anterioridad, François Ewald había dedicado algunos párrafos al tratamiento del derecho en la obra de Foucault, con posterioridad se publicaron varios artículos, hasta que en 2009 apareció Foucault´s Law de Ben Golder y Peter Fitzpatrick, quienes al año siguiente realizaron una compilación titulada Foucault and Law, con artículos ya publicados pero dispersos, y en el 2013 Golder compiló Re-reading Foucault: On Law, Power and Rights.

Published: April 2020

The main objective of modeling a switched reluctance machine is to derive a mathematical function to relate the outputs to the inputs. Due to the nonlinear relationship between the variables of torque, flux linkage, current and angular position of the rotor, Switched Reluctance Machine (SRM) modeling is a very challenging task and an open problem. Modeling is usually done in two situations, modeling a single machine, or modeling a set of machines. Each one must fulfill different requirements. This work presents a survey of different SRM modeling approaches, evaluating its advantages and limitations when modeling a single machine or a set of machines.

The aim is to understand the potential of transmedia storytelling in the recruitment process, in line with the technological and social changes of the world. A more detailed example of a Heineken campaign using transmedia storytelling is described, exploring how it could be seen as a way of attracting candidates and promoting the image of the company as an employer. We conclude that transmedia storytelling allows organizations to get closer to their target audiences by employing a synergetic process susceptible to influence the image of organizations and the way candidates interact and share information about organizations, choosing their level of involvement.
Agricultural holdings and farms: The right to development
Authors: Denisov V.I. , Potravnyi I.M.
Published: April 2020

Subject. We consider development prospects for agricultural organizations of different categories.
Objectives. The aim is to conduct a multifaceted study of positive and negative aspects of the production activities of agricultural holdings and farms, assessed by their contribution to the economic and social development of Russia.
Methods. We employ general scientific methods of research.
Results. The paper emphasizes high competitive performance of agricultural holdings, which displace farms from the market. This is mainly due to the administrative support to large corporate structures by regional and federal governments. We show that in the event of redistribution of available public funds to agriculture and increased assistance for farmers, the latter will be at a much higher level of economic efficiency of production vs. the current level. At the same time, the main advantage of small farms over agroholdings, i.e. the predominance of their environmental preservation-style of economy, will remain.
Conclusions. The growing economy of farms and their interest in higher output will assist in restoration of agricultural lands that are now abandoned. It is likely that in the future, farms will outpace agricultural holdings in their development and become leading large-scale producers of agricultural goods.
Researching the economic dynamics of high technology products
Authors: Leonov A.V. , Pronin A.Yu.
Published: April 2020

Subject. The article addresses the issue of adequate representation of economic dynamics. It considers the need to take into account internal nonlinear processes being an important factor and additional mechanism for managing the economic dynamics.
Objectives. The purpose is to rationalize a transition to a new probabilistic mapping of economic dynamics based on modern methods of nonlinear dynamics, which enables to establish the relationship between internal nonlinear processes and macroeconomic indicators of the economic system.
Methods. We employ a systems analysis of stages of State-run programs formation, a probabilistic approach to representing the economic dynamics on the basis of fundamental concepts and methods of nonlinear dynamics.
Results. We analyzed the cycles of government program formation for developing the high-tech products, established the identity of the main stages of economic and nonlinear dynamics. We also designed a methodology for studying the economic dynamics, which rests on the use of nonlinear dynamics methods. Modeling the processes of economic dynamics made it possible to determine the causes of its sensitivity to initial conditions and exponential divergence of its trajectory at initial stages of government programs formation. The paper presents methods to choose the optimal model of economic dynamics when substantiating and drafting the said programs.
Conclusions. The findings can be used to improve methodological tools for managing the creation of high-tech products when elaborating long-term technological programs, to reduce risk inherent in their implementation, to determine methods and ways for sustainable innovative and technological development of the country.
Financial impact of stakeholder policy in conditions of economic instability: An empirical analysis of panel data
Authors: Badykova I.R.
Published: April 2020

Subject. The article deals with a policy towards corporate stakeholders as a tool to enhance financial performance.
Objectives. The study aims at conceptualizing and presenting in a systematic way the accumulated knowledge on stakeholders' impact on business; identifying the influence of employee-related corporate policy on corporate financial performance in conditions of the informationally inefficient Russian market.
Methods. I employ general theoretical methods, including synthesis, deduction and induction, quantitative and empirical methods, namely the analysis of balanced panel data based on the application of random-effects and fixed-effects models.
Results. I conducted an empirical research to determine the relation between corporate social responsibility towards one of the most important stakeholder groups, i.e. the employees, and the corporate financial performance. The relation between expenditures on employees' education and development and the EBITDA margin was statistically insignificant. The value of coefficient using the core variables is negative for both models.
Conclusions. The analysis shows that against the backdrop of prolonged economic stagnation and weak market informational efficiency in Russia, the social responsibility towards company employees as measured by expenses on retraining and professional development has no statistically significant effect on financial performance. It is perceived as a discretionary expenditure, negatively affecting the financial results. However, in efficient financial markets, these expenses are viewed as investments, which in the long run may demonstrate positive results.

Published: April 2020

Subject. The paper deals with the economic analysis of university spatial networking.
Objectives. The purpose is to work out methods for economic analysis of spatial network of higher education institutions based on the European experience and information sources of the space location of universities in the EU countries.
Methods. The study rests on theoretical analysis of the higher education institutions network as a spatially localized system, economic and statistical techniques of sampling and grouping, methods for comprehensive economic indicators of distribution, indexing, and ranking.
Results. We underpinned approaches to the university network development as part of the science-push and the local development driver model; developed information support and methods for economic analysis of spatial organization of university networks; presented and tested the methodology for assessing the university spatial networking.
Conclusions. The offered methods enable to obtain the estimates of even distribution of universities across a country, which is achieved by the country policy. These methods may be recommended for sound management decisions and strategies for higher education institutions development, spatial and socio-economic growth, policies designed to equalize the level of social and economic development of subjects of the Russian Federation.
Changes in the consumer credit market in conditions of tightening of the Bank of Russia's macroprudential measures in 2019
Authors: Evstaf'ev K.A.
Published: April 2020

Subject. In 2019, the Bank of Russia updated and toughened regulatory approaches by increasing the capital requirements depending on borrowers’ debt burden. The disclosed bank statements have significantly changed and become more complicated. This enabled a comprehensive statistical analysis of the consumer credit market structure in 2019, based on effective interest rate and payment-to-income (PTI).
Objectives. The purpose of the study is to assess how the strengthened capital adequacy requirements influence the change in the effective interest rate on consumer loans and how banks consider debt burden of borrowers when issuing such loans.
Methods. The study draws on methods of statistical analysis of reporting forms presented by credit organizations in open databases of the Bank of Russia. A dynamic model is used for analytical determination of average maturity of consumer loans based on their effective interest rate.
Results. I estimated trends in outstanding consumer loans in all ranges of their full cost (effective interest rate), analyzed the impact of the new requirements of the Bank of Russia with respect to risk cover on consumer loans by banks’ own funds on the capital adequacy of banks in the medium term.
Conclusions. In 2019, loans with low effective interest rate (less than 20%) demonstrated the lowest growth rates; the volume of consumer loans to borrowers with high debt burden did not reduce; only a small number of banks incurred risk to capital adequacy due to strengthened requirements. Thus, the Bank of Russia’s macroprudential measures for consumer lending regulation cannot be regarded as effective.

Demographic maps can present statistical data on demographic education levels, population stages, family stages, education levels, age, and number of lives in families based on participation in the National Health Insurance (JKN). Where every Regional Apparatus Organization (OPD) in West Bandung Regency that requires population control data needs a data integration and performance optimization, so that in each Regional Apparatus Organization (OPD) in work there is no more duplication of work. In this study, it is expected to be able to map all information about population control data to help the community and Regional Apparatus Organizations (OPD) in West Bandung Regency in order to obtain information clearly from population control data based on the results of family data collection which will make it easier for Regional Apparatus Organizations (OPD) related in order to help the entire community in West Bandung Regency. In this case a solution will be made by utilizing the QGIS application in solving problems where for population control maps can be integrated in the Regional Apparatus Organization (OPD) in West Bandung Regency.
Disability Rights and the Discourse of Justice
Authors: Bagenstos Samuel R.
Published: April 2020

Although the ADA has changed the built architecture of America and dramatically increased the visibility of disabled people, it has not meaningfully increased disability employment rates. And the statute continues to provoke a backlash. Disability rights advocates and sympathizers offer two principal stories to explain this state of affairs. One, the “lost-bipartisanship” story, asserts that disability rights were once an enterprise broadly endorsed across the political spectrum but that they have fallen prey to the massive rise in partisan polarization in the United States. The other, the “legal-change-outpacing-social-change” story, asserts that the ADA was essentially adopted too soon—that the legislative coalition came together to pass the law before society as a whole was ready for it, leading to a backlash. There is something to be said for both stories. But the most important point is what connects them. The ADA was a bipartisan achievement largely because the efforts to pass the statute—in a brilliant tactical move—skirted difficult arguments about justice. Instead, they relied explicitly on a discourse of costs and benefits—and they relied implicitly on a discourse of charity and pity. But as soon as the ADA was adopted and the burdens imposed by it became apparent, the cost-benefit and charity/pity discourses reached their limit in providing support for the statute. To secure support for disability rights in the future, advocates will need to rely on a discourse of justice. And that will require renewed efforts at social, and not just legal, change.
