Direct Shear Strength Characteristics in Unsaturated Compacted Soil Surface Coverage on Pb(II)-Polluted Tailings Reservoir under Low Normal Stress
Authors: Li Yong , Hu Zhenqi
Published: July 2022

Mining activities generate a large amount of solid waste called tailings, and it often contains a certain number of heavy metals, depending on the different types of minerals. To avoid disasters caused by the diffusion of tailings and their infiltration into surface water, mines often use tailings ponds as a surface coverage structure. This study mainly focused on the shear strength of surface coverage isolation layer soil under low normal stress. The soil isolation layers with different values of dry bulk density, water content, bentonite content, and Pb(II) ion concentration were treated with direct shear strength under normal stress at 12.5, 25, 50, and 100 kPa. It was found that when the dry bulk density was increased from 1.1 g/cm3 to 1.3 g/cm3, the shear strength increased by 49.3%~117.2%, and when the water content was decreased from 24% to 16%, the shear strength increased by one to three times. With the addition of bentonite in proportions from 18% to 30%, shear strength increased by 1.9 to 116.9 kPa, and the degree of improvement was related to both dry bulk density and water content; the specimens with bentonite added were more sensitive to Pb(II) ion concentration, and when the specimen with 24% bentonite addition was compared with the specimen without the addition of bentonite, both under a Pb(II) ion concentration of 5 mg/L, the shear strength decreased by 8.1~35.6 kPa, the internal friction angle decreased by 0.5~9.7°, the cohesion force decreased by 5.8~37.7 kPa, and the shear modulus decreased by 5~12 kPa/mm. Therefore, in order to maintain good mechanical properties in the surface covering structure, it is necessary to maintain a high dry bulk density, low water content, and bentonite content of no less than 24%.

This work aimed to improve the functionality of beer by increasing the level of antioxidant activity through the addition, up to acceptable sensory amounts, of red grape skin extract. A commercial hefeweizen beer was supplemented with different concentrations (1, 5, and 10 mg/mL) of grape skin extract (GSE). The phytochemical characterization of GSE and supplemented beer samples was achieved in terms of the total phenolic content (TPC), total flavonoid content (TFC), and total monomeric anthocyanin content (TMA). Additionally, the antioxidant activity of the samples was assessed using a variety of radical scavenging tests. The addition of various concentrations of GSE significantly increased the TPC and TFC content of beer samples, from 3.167 to 4.477 mg GAE/mL and from 0.841 to 1.226 mg CE/mL, respectively. The TMA content of the GSE-supplemented white beer samples ranged from 0.005 to 0.027 mg C3G/ mL. Consequently, the antioxidant capacity of the beer samples increased with the level of GSE addition. The obtained results suggest the potential of using GSE as a functional ingredient for beer production.

Authors: Huang Bingsheng , Zhang Fusheng
Published: July 2022

With the increase in people’s travel demands, the air pollution generated by the means of transportation they take is also becoming more and more serious. Among them, in the process of people’s travel, the exhaust pollution caused by traffic congestion is particularly serious. Accurately identifying various regimes of oversaturation and taking effective control strategies play a key role in alleviating traffic congestion. There are three regimes of evolution during an oversaturated scenario: loading, oversaturated operation, and recovery. In the traffic signal control under the oversaturated scenario, the corresponding control targets and methods should be adopted based on the regime of oversaturation. In this paper, the multi-objective attributes and their trajectory data of each movement at the intersection are analyzed. Based on the oversaturation severity index, the traffic volume, and the queuing on the movement, the identification and cause analysis of each regime of the oversaturation are carried out. The examples and simulation results proved that the method proposed in this paper could effectively analyze the cause and degree of oversaturation and identify its regime. This has important implications for alleviating traffic congestion and reducing vehicle carbon emissions.

Historically, carbon dioxide emissions from transport have been a globally discussed and analyzed problem. The adoption of flex fuel vehicles designed to run ethanol–gasoline blends is important to mitigate these emissions. The main purpose of this paper is to analyze the impact of the ethanol–gasoline price ratio on different vehicle models, and discuss the opportunities to increase ethanol consumption from this perspective. Our analysis shows that the use of a unique fuel economy ratio for all flex–fuel vehicles in the country significantly reduces the opportunity of some customers to purchase hydrous ethanol. The paper also discusses possible actions to provide adequate information that may increase the possibility of fuelling vehicles with a high-level ethanol blend.
Accounting Conservatism, R&D Manipulation, and Corporate Innovation: Evidence from China
Authors: Shen Yi , Ruan Qingsong
Published: July 2022

Research and development (R&D) is the main driver for the sustainable development of corporate innovation. Given the prevalence of information asymmetry in R&D, executives opportunistically manipulate R&D investment. While accounting conservatism as a corporate governance mechanism can effectively reduce information asymmetry, few studies have focused on the relationship between the two. Based on Chinese listed companies in 2008–2019, this paper investigates the impact of accounting conservatism on R&D manipulation, as well as the moderating effect of internal control quality and tax enforcement efforts on this relationship. The results indicate that not only are the results more significantly negative in subgroups of low-level internal control and tax collection, but the coefficients of their cross-sectional variables are also positive. Therefore, accounting conservatism can effectively deter R&D manipulation, and this effect is weakened by internal control and tax enforcement. Additionally, the impact of accounting conservatism on manipulation differs in direction and lifecycle. The negative conservatism–manipulation relationship is more significant for upward manipulation and growing enterprises. Further research also suggests that conservatism’s inhibitory effect on R&D manipulation is mediated by financial constraints, which enhances corporate innovation efficiency. The conclusions not only provide empirical evidence for the corporation to improve R&D efficiency but also provide the basis for the authorities to promote innovation supervision.

Published: July 2022

Vanadium tailings are a common solid waste in the vanadium industry. As they are rich in Fe, vanadium tailings could be a potential raw material for the blast furnace. However, the presence of approximately 4% Na2O in vanadium tailings is a major impediment to its return to the blast furnace. A novel method for removing sodium from vanadium tailings by calcification roasting and subsequent NaOH leaching was proposed in this work. The method demonstrated that calcification roasting of vanadium tailings can not only volatilize a part of sodium but also facilitate the dissolution of sodium during the subsequent NaOH leaching process. The thermodynamic analysis and behaviors of vanadium tailings during calcification roasting were systematically investigated. The transformation of sodium-containing phases in vanadium tailings during calcification roasting was studied. Further, the promoting effect of calcification roasting on sodium leaching by NaOH was clarified. The total removal efficiency of sodium was 80.37% under optimal conditions, and the residue obtained after sodium removal can be used as a raw material in the blast furnace process for in-plant recycling.
Stackelberg Game Analysis of E-Waste Recycling Stakeholders under Recovery Time Sensitivity and CRMs Life Expectancy Sensitivity
Authors: Li Shu-Hao , Sun Qiang
Published: July 2022

In order to discuss the participation selection strategy of relevant subjects in WEEE recycling, a Stackelberg game model of “recyclers—remanufacturers—government” in a WEEE recycling network is constructed, and the system’s stability strategy and conditions are analyzed. Besides this, the direct and indirect effects of recovery time sensitivity, CRMs’ life expectancy sensitivity, and government subsidies on the optimal decision-making of both recyclers and remanufacturers are explored. The results show that the system can achieve a stable and ideal equilibrium, and achieve win–win for all parties, through reasonable profit transfer and cost-sharing. The dual sensitivity of manufacturers’ demand and policy subsidies has the same qualitative impact on the decision variables of the recyclers and remanufacturers. The subsidies vary depending on the CRMs’ recovery effort level of remanufacturers, and these can incentivize the remanufacturers to increase CRMs’ life expectancy. Moreover, a cost-sharing contract between recyclers and remanufacturers can avoid “free-riding” behavior in WEEE recycling. The research can assist in the benefit coordination and behavior adjustment of WEEE recycling members, and provide a theoretical basis for governments to formulate appropriate recycling subsidies to promote the formal recycling of E-waste.

Published: July 2022

Very drastic environmental changes require the development of an adaptive performance management framework that supports the strengths of the company’s structure. The position of internal CSR as a resource that can solve performance problems needs to be proved. The purpose of the study was to analyze the effect of internal corporate social responsibility on job performance through employee well-being. To this end, this causal study surveyed 282 non-managerial employees at four strategic industrial state-owned enterprises in Indonesia. The respondents were recruited using the proportional random sampling technique. The collected data were analyzed using SEM with SPSS 26. The results showed that changes in job performance can be predicted by the adequacy of work resources and personal resources. Both resources can be realized by the existence of corporate social responsibility intended for employees. Internal corporate social responsibility was found to encourage increased work engagement and decrease burnout, which ultimately improves job performance. Internal CSR is an important personal and work resource for employees. Internal CSR is the company’s main orientation in an effort to strengthen the company’s performance structure while ensuring the implementation of the company’s ethical responsibility in its environment. From the theoretical perspective, this study implied the need for exploring the concept of internal corporate social responsibility to expand our understanding of the relationship between corporate social responsibility and personal and work resources and employee performance. Meanwhile, the practical implications of this study highlight the importance of microlevel corporate social responsibility programs to meet personal and work resource needs so that companies benefit from high employee engagement and low burnout in order to improve adaptive performance and the structure of the company’s performance.

As the world pays more attention to carbon reduction, it is of great significance to identify the factors of CO2 to achieve carbon peaking and carbon neutrality goals for China. Therefore, this paper explores the factors of CO2 from the perspective of CO2 mitigation potentials (CESP) and analyzes the heterogeneity of each factor. We first employ the DEA-IDA model framework to analyze the CESP and influencing factors of each region, and then use geographically and temporally weighted regress to analyze the spatiotemporal heterogeneity of influencing factors, the efficiency, coal proportion, energy intensity, per capita GDP, urbanization rate, electrification rate, trade, economic structure, and climate conditions. The research results show that: (1) for 1 unit increase in per capita CO2, the per capita CESP increases by 0.56 units. The CESP of the central and western regions is greater than that of the eastern regions, and the improvement of resource utilization efficiency can achieve the peak in advance. (2) Per capita GDP and energy intensity are the main positive factor and negative factor, respectively, and the impact of efficiency changes on CESP is mostly positive. (3) Efficiency is the most influential factor affecting the CESP; among them, a 1% increase in efficiency in Hebei can reduce the CESP of 62.47 Mt. In regions dominated by clean power, the impact of electrification rates is negative. The rest of the factors also showed spatiotemporal heterogeneity. Our findings have important policy implications, especially in how to effectively reduce carbon emissions to formulate more appropriate policy.
Digital Technology Deployment and the Circular Economy
Authors: Wynn Martin , Jones Peter
Published: July 2022

The relationship between digital technologies and the circular economy, both characterised as disruptive, is attracting increasing attention in company boardrooms, policy and pressure groups and in academic communities. Nevertheless, studies to date highlight a lack of understanding of how digital technologies enable organisations to improve their resource flows and value creation to promote the circular economy. This article looks to address this gap in the academic literature by an examination of if and how a small number of organisations are using digital technologies to support their sustainability objectives and circular economy initiatives. The research approach is inductive, using questionnaires and interviews with IT professionals employed in a range of organisations. The article concludes that where organisations are pursuing circular economy initiatives, the connection with digital technology deployment is not evident, even though a more general association with sustainability is. Digital technologies are bringing about greater efficiencies, improved processes and better data management, which are supporting and enabling sustainability objectives, but a more direct linkage with the circular economy will require clearer use cases of how specific digital technologies can progress the circular economy, both within organisations and across the supply chain. Enhanced information systems that facilitate the reporting and analysis of the operational performance of circular economy activities against set objectives will also be needed.

Up to 30% of ischemic stroke cases are due to large vessel occlusion (LVO), causing significant morbidity. Studies have shown that the collateral circulation of patients with acute ischemic stroke (AIS) secondary to LVO can predict their clinical and radiological outcomes. The aim of this study is to identify baseline patient characteristics that can help predict the collateral status of these patients for improved triage. In this IRB approved retrospective study, consecutive patients presenting with AIS secondary to anterior circulation LVO were identified between September 2019 and August 2021. The baseline patient characteristics, laboratory values, imaging features and outcomes were collected using a manual chart review. From the 181 consecutive patients initially reviewed, 54 were confirmed with a clinical diagnosis of AIS and anterior circulation LVO. In patients with poor collateral status, the body mass index (BMI) was found to be significantly lower compared to those with good collateral status (26.4 ± 5.6 vs. 31.7 ± 12.3; p = 0.045). BMI of >35 kg/m2 was found to predict the presence of good collateral status. Age was found to be significantly higher (70.5 ± 9.6 vs. 58.9 ± 15.6; p = 0.034) in patients with poor collateral status and M1 strokes associated with older age and BMI.

Published: July 2022

On a group level, satisfaction with botulinum neurotoxin (BoNT) treatment in neurological indications is high. However, it is well known that a relevant amount of patients may not respond as expected. The aim of this study is to evaluate the BoNT treatment outcome on an individual level using a statistical single-case analysis as an adjunct to traditional group statistics. The course of the daily perceived severity of symptoms across a BoNT cycle was analyzed in 20 cervical dystonia (CD) and 15 hemifacial spasm (HFS) patients. A parametric single-case autoregressive integrated moving average (ARIMA) time series analysis was used to detect individual responsiveness to BoNT treatment. Overall, both CD and HFS patients significantly responded to BoNT treatment with a gradual worsening of symptom intensities towards BoNT reinjection. However, only 8/20 CD patients (40%) and 5/15 HFS patients (33.3%) displayed the expected U-shaped curve of BoNT efficacy across a single treatment cycle. CD (but not HFS) patients who followed the expected outcome course had longer BoNT injection intervals, showed a better match to objective symptom assessments, and were characterized by a stronger certainty to control their somatic symptoms (i.e., internal medical locus of control). In addition to standard evaluation procedures, patients should be identified who do not follow the mean course-of-treatment effect. Thus, the ARIMA single-case time series analysis seems to be an appropriate addition to clinical treatment studies in order to detect individual courses of subjective symptom intensities.
From Soft Dirac Monopoles to the Dirac Equation

In the model of topological particles we have four types of topologically stable dual Dirac monopoles with soft cores and finite mass. We discuss the steps for getting a Dirac equation for these particles. We show for the free and the interacting case that we arrive at the Dirac equation in the limit, where the soft solitons approach singular dual Dirac monopoles.

HIV-HCV co-infected subjects are at risk of liver fibrosis which may be linked to immune imbalances. Direct-acting antivirals (DAAs) represent the mainstay of HCV treatment in co-infected individuals, yet their effects on immune cell populations playing a role in fibrogenesis is unknown. We assessed γδ T-cell phenotype and function, Treg and Th17 frequencies, as well as γ-globulins and B-cell activation in 47 HIV-HCV co-infected and 35 HCV mono-infected individuals prior to and following DAA treatment (SVR12). Γδ T-cell activation decreased in both groups yet persisted at higher levels in the HIV-HCV co-infected subjects. No differences were registered in terms of γδT-cell function. Of note, the Vδ2/Th17 ratio, inversely linked to liver damage, increased significantly in the two groups upon treatment, yet a negative correlation between the Vδ2/Th17 ratio and liver function enzymes was found in the co-infected subjects alone. B-cell activation and γ-globulin levels decreased in both settings, yet B-cell activation remained higher in the HIV-HCV co-infected individuals. In HIV-HCV co-infected and HCV mono-infected participants, the effect of DAA was limited to γδ T- and B-cell activation as well as γ-globulin concentrations and the Vδ2/Th17 ratio, with no changes in γδ T-cell function and Treg frequencies. Importantly, γδ T- and B-cell activation remained at higher levels in the co-infected individuals than in those with HCV mono-infection alone. The persistence of such alterations within these cell subsets may be associated with the risk of hepatic and extrahepatic complications.

Reinfection risk is a great concern with regard to the COVID-19 pandemic because a large proportion of the population has recovered from an initial infection, and previous reports found that primary exposure to SARS-CoV-2 protects against reinfection in rhesus macaques without viral presence and pathological injury; however, a high possibility for reinfection at the current stage of the pandemic has been proven. We found the reinfection of SARS-CoV-2 in Syrian hamsters with continuous viral shedding in the upper respiratory tracts and few injuries in the lung, and nasal mucosa was exploited by SARS-CoV-2 for replication and shedding during reinfection; meanwhile, no viral replication or enhanced damage was observed in the lower respiratory tracts. Consistent with the mild phenotype in the reinfection, increases in mRNA levels in cytokines and chemokines in the nasal mucosa but only slight increases in the lung were found. Notably, the high levels of neutralizing antibodies in serum could not prevent reinfection in hamsters but may play roles in benefitting the lung recovery and symptom relief of COVID-19. In summary, Syrian hamsters could be reinfected by SARS-CoV-2 with mild symptoms but with obvious viral shedding and replication, and both convalescent and vaccinated patients should be wary of the transmission and reinfection of SARS-CoV-2.

Since 2020, the COVID-19 (Coronavirus Disease 2019) has quickly become a worldwide health problem. Ophthalmologists must deal with symptoms as well. For the positive detection in the conjunctival sac swab in COVID-19 patients hospitalized in Slovakia during March 2021 in four hospital centers, we used a test based on a polymerase chain reaction (PCR). In a group of 484 patients, 264 males (55%) and 220 females (45%) with clinical symptoms were identified with COVID-19 as a clinical diagnosis. The PCR test swab results from the conjunctival sac taken on the same day were positive in 58 patients (12%), 31 males (with a mean age of 74.6 ± 13.59 years) and 27 females (with a mean age of 70.63 ± 14.17 years); negative in 417 patients (86%); and 9 patients (2%) had an unclear result. The cycle threshold values comparing the nasopharynx and conjunctiva were also different in the group of all patients divided by age and gender. In COVID-19 patients the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was detectable using PCR test in the nasopharynx but also in the conjunctival sac swab, where the positivity rate was only 12%.

Se realizó un análisis de la producción de crías de tilapia Oreochromis niloticus en instalaciones acuícolas en México de 2014 a 2021, a partir de la producción pesquera y acuícola registrada a nivel nacional. Para ello se analizaron los registros de producción de crías de tilapia en laboratorios, los volúmenes de cosechas anuales registrados en las instalaciones acuícolas que operan en las diferentes entidades federativas y las capturas de tilapia registradas de 2009 a 2018. En 2018 se produjeron en México 168.359 t de tilapia y se importaron 127.981 t, con un consumo nacional aparente de tilapia registrado de 298.644 t. Ese año se produjeron 169,2 millones de crías de tilapia (Conapesca 2018). Para cubrir el déficit de tilapia por la importación de 127.981 t, se requiere teóricamente una producción adicional estimada en 511,9 y 383,9 millones de crías de tilapia, considerando los escenarios de siembra de 4 y 3 organismos para cosechar un kilogramo (2 organismos de 500 g de peso promedio), con supervivencias durante su cultivo del 50 y 66,6 % y producciones de 7,5 - 10 t por ha, respectivamente. Se analizaron los sistemas de producción de tilapia a nivel extensivo y semi-intensivo por su sustentabilidad y se emiten conclusiones técnicas para mejorar el aprovechamiento de este recurso biológico-pesquero, que impacta favorablemente en la socioeconomía de las diferentes regiones donde se cultiva.

Published: July 2022

The stimulus-responsive room-temperature phosphorescence (RTP) materials have become an increasingly significant topic in the fields of bioimaging, sensing, and anticounterfeiting. However, this kind of materials is scarce to date, especially for the ones with delicate stimulus-responsive behavior. Herein, a universal strategy for multilevel thermal erasure of RTP via chromatographic separation of host-guest doping RTP systems is proposed. The tunable host-guest systems, matrix materials, heating temperature, and time are demonstrated to allow precise six-level data encryption, QR code encryption, and thermochromic phosphorescence encryption. Mechanistic study reveals that the thermal-responsive property might be attributed to molecular thermal motion and the separation effect of the silica gel, which provides expanded applications of host-guest RTP materials such as cold chain break detection. This work offers a simple yet universal way to construct advanced responsive RTP materials.

Published: July 2022

Background and aims: Skin ulcers are caused by various reasons such as physical, chemical, and biological damages. Wound healing has long been considered one of the most important issues in surgery. Extensive research has been employed in this field and various chemical, herbal, homeopathic, and physical methods such as laser therapy have been used for treatment. Nowadays, wound healing is one of the most important aims of medical science. Furthermore, people prefer to use natural drugs because of fewer side effects. Therefore, the present study was designed considering these issues. Methods: For this study, 6 albino rabbits with an average weight of 3 kg were purchased. After preparing the rabbits, two pairs of full-thickness wounds were created in a completely round shape with a diameter of almost 6.30 mm on both sides of the spine in two anterior and posterior parts at a distance of 3 cm from the midline of the body. The animals were divided into 2 groups of 3 rabbits, including 1 experimental group and 1 control group. The wounds of the experimental group were treated with fig fruit extract while the wounds of the control group received no treatment. The wounds were macroscopically examined at 4, 7, 12, 16, and 20 days after surgery. Results: The results of t-test showed a significant difference (P<0.05) among the groups on all days. Meanwhile, the average wound area significantly decreased in the group which was treated with the extract of fig fruit. Conclusion: This study showed that fig fruit extract contains phenolic compounds with antioxidant, antimicrobial, and anti-inflammatory properties which can accelerate the wound healing process.

Published: July 2022

Background and aims: Since cardiovascular diseases (CVDs) are the most common cause of morbidity and mortality in the world, this systematic review aimed to investigate the effectiveness and mechanism of aromatherapy on hemodynamic parameters in patients with CVDs. Methods: This review was performed in accordance with PRISMA guidelines. Using relevant keywords, an extensive search was done in 1.30.2022 in most important databases including Scopus, PubMed, Web of Science, and Google Scholar. A form was designed for recording data related to randomized clinical trials (RCTs), hemodynamic changes (e.g., heart rate, respiratory rate, systolic, and diastolic blood pressure), and information about possible mechanisms in non-RCT works was also extracted. Findings: In RCTs, aromatherapy with lavender (Lavandula angustifolia) oil, orange (Citrus sinensis) oil, lemon (Citrus limon), rose (Rosa damascena), and almond (Prunus dulcis) oil regulates pulse rate, respiratory rate, and blood pressure in patients with CVD. Aromatherapy can affect the sympathetic and parasympathetic systems through inducing local effects on veins, resulting in vasodilation, increased blood flow, and decreased peripheral resistance. Conclusion: Aromatherapy can be used as a complementary agent for regulating heart rate, blood pressure, and respiratory rate in patients with CVD. However, certain precautions such as allergic reactions in patients should be taken before administration.

Published: July 2022

The development of interfaces for technical systems, in contrast to general-purpose graphical user interfaces, is associated with several features that must be taken into account in order to increase the efficiency of human-machine interaction. If the general theory of user interfaces focuses on color-graphic and psycho-emotional aspects, then for technical systems, the correspondence of the operator’s activity comes to the fore, and in some cases, the organization of this activity by purposefully displaying individual windows and their parts. In order to take into account, the specifics of the operator›s activity, many attempts are being made to create new approaches to creating interfaces, but not all of them solve the problem. This article provides an overview of modern conceptual approaches to the design of user interfaces in terms of their applicability for implementation in technical systems.

Aim. The purpose of the article is to study the cryptographic strength characteristics of Boolean functions used in the blender algorithm. This algorithm is designed for information security tasks as part of a pseudorandom sequence generator. Methods. The methods of cryptographic Boolean functions theory, the methods of analysis and comparison were used in the work. Results. The general features of the blender Boolean functions are formulated. To assess their cryptographic strength, a computational study of compliance with criteria such as balancedness, algebraic degree, the presence of fictitious variables, the absence of linear structures, correlation immunity, high nonlinearity, avalanche criterion, etc. was performed. A comparison is made with similar results for Boolean functions that are part of nonlinear s-blocks of known cryptographic algorithms. Conclusions. The ability to adjust the blender dimension to obtain blocks of the desired size, forming the output sequence, allows increasing the values of some characteristics of Boolean functions cryptographic strength. It is detected that some cryptographic strength indicators of the Boolean blender functions (balancedness, nonlinearity and global avalanche characteristic) have asymptotic regularities of behavior. The results of the study makes it possible to consider the level of cryptographic strength of the blender Boolean functions acceptable for use in cryptographic protection systems.

The problems of modeling the structures of organizational systems by methods of network analysis are considered. Various aspects of the structure description based on the use of bipartite graphs and affiliation networks are considered. In order to identify communities in the structures, indicators and methods of clustering and modularity were used. To test the proposed approach, an organizational system for designing information systems was used. The results of the analysis of the proposed structures are presented.

The development of the modern economy associated with the development of natural resources is greatly influenced by information technologies of the platform type. In this area the formation of new economic entities of business structures of the resource type is taking place – ecosystems capable of solving new problems on the principles of the digital economy. The work is devoted to the methodological and technological aspects of the development and formation of resource-type business systems. The possibilities of platform interaction of business systems of a resource type are considered on the example of a resource region (Krasnoyarsk Territory). The key idea of the study: the basis for the development of resource-type business eco- systems in a resource-rich region is cooperation and network interactions which are effectively analyzed within the framework of the author’s technology – functional-environmental analysis. The paper proposes a variant of algorithmic support for solving expert problems of interaction within the framework of an information system that contains elements of a digital platform. The main result of the research is to substantiate and briefly describe the proposed implementations of algorithms and calculation schemes built into the relevant elements of the information system (digital platform) as a modern approach to solving problems of interaction and forecasting. The study was financially supported by the Russian Foundation for Basic Research, the Government of the Krasnoyarsk Territory an d the Krasnoyarsk Regional Science Foundation within the framework of scientific project No. 20-410-242916.

En este artículo intentamos abordar cómo durante algunas coyunturas precisas del período de entreguerras, la Constitución y las instituciones políticas argentinas fueron objeto de debate en algunos medios académicos norteamericanos y argentinos vinculados al ámbito del derecho. A través de una serie de fuentes poco exploradas –discursos, correspondencia y artículos académicos–, intentamos examinar ciertas narrativas generadas en torno de las instituciones políticas argentinas por parte de algunos juristas argentinos y americanos, que tuvieron a EE.UU. como punto de encuentro y al texto constitucional como objeto de análisis.

This research was conducted the Financial Statements of the Consumer Goods Industry listed on Bursa Efek IndonesiaIn 2014-2019. The phenomenon occurs is the consumer goods industry experiences fluctuating amount of net profit so Return On Equity (ROE) is the same. Most of the capital cannot meet the amount of debt, which makes the value of Debt to Equity Ratio (DER) high. In addition, companies continue to provide dividends even though experience losses. The purpose of this was to determine effect of ROE and DER on Dividend Payout Ratio (DPR). Using Panel Data Regression Analysis through three approach models, namely common effect, fixed effect and random effect. Chow test, Hausman test and Langrangian multiplier test were carried out to find appropriate approach. The result is that ROE and DER simultaneously have a significant effect on DPR. Furthermore, partially ROE and DER have an effect on DPR.
