Background: Chronic renal failure (CRF) results in significant dyslipidemia and profound changes in lipid metabolism. Polyporus umbellatus (PPU) has been shown to prevent kidney injury and subsequent kidney fibrosis.

Methods: Lipidomic analysis was performed to explore the intrarenal profile of lipid metabolites and further investigate the effect of PPU and its main bioactive component, ergone, on disorders of lipid metabolism in rats induced by adenine. Univariate and multivariate statistical analyses were performed for choosing intrarenal differential lipid species in CRF rats and the intervening effect of n-hexane extract of PPU and ergone on CRF rats.

Results: Compared with control group, decreased creatinine clearance rate indicated declining kidney function in CRF group. Based on the lipidomics, we identified 65 lipid species that showed significant differences between CRF and control groups. The levels of 12 lipid species, especially fatty acyl lipids including docosahexaenoic acid, docosapentaenoic acid (22n-3), 10,11-Dihydro-12R-hydroxy-leukotriene C4, 3-hydroxydodecanoyl carnitine, eicosapentaenoic acid, hypogeic acid and 3-hydroxypentadecanoic acid had a strong linear correlation with creatinine clearance rate, which indicated these lipid species were associated with impaired renal function. In addition, receiver operating characteristics analysis showed that 12 lipid species had high area under the curve values with high sensitivity and specificity for differentiating CRF group from control group. These changes are related to the perturbation of fatty acyl metabolism. Treatment with PPU and ergone improved the impaired kidney function and mitigated renal fibrosis. Both chemometrics and cluster analyses showed that rats treated by PPU and ergone could be separated from CRF rats by using 12 lipid species. Intriguingly, PPU treatment could restore the levels of 12 lipid species, while treatment with ergone could only reverse the changes of six fatty acids in CRF rats.

Conclusion: Altered intrarenal fatty acyl metabolites were implicated in pathogenesis of renal fibrosis. PPU and ergone administration alleviated renal fibrosis and partially improved fatty acyl metabolism. These findings suggest that PPU exerted its renoprotective effect by regulating fatty acyl metabolism as a potential biochemical mechanism. Therefore, these findings indicated that fatty acyl metabolism played an important role in renal fibrosis and could be considered as an effective therapeutic avenue against renal fibrosis.

Misuse of the psychostimulant methamphetamine (METH) could induce serious hepatotoxicity. Our previous study revealed the effects of luteolin on alleviating METH-induced hepatotoxicity, however, the detailed mechanisms have not been elucidated. In this study, rats were orally pretreated with 100 mg/kg luteolin or sodium dodecyl sulfate water, and then METH (15 mg/kg, intraperitoneal [i.p.]) or saline was administered. Histopathological and biochemical analyses were used to determine the alleviative effects of luteolin. Based on the RNA-sequencing data, METH induced 1859 differentially expressed genes (DEGs) in comparison with the control group, which were enriched into 11 signaling pathways. Among these DEGs, 497 DEGs could be regulated through luteolin treatment and enriched into 16 pathways. The p53 signaling pathway was enriched in both METH administered and luteolin pretreated rats. Meanwhile, luteolin significantly suppressed METH-induced elevation of p53, caspase9, caspase3, cleaved caspase3, the ratio of Bax/Beclin-2, as well as autophagy-related Beclin-1, Atg5, and LC3-II. Luteolin also relieved METH-induced hepatotoxicity by decreasing inflammation factors, including TNF-α, IL-1β, and IL-18. Moreover, the levels of PI3K, p-Akt, and the normalized ratio of p-Akt/Akt declined after METH administration, whereas luteolin pretreatment failed to reverse these effects. Our results suggest that luteolin alleviates METH-induced hepatic apoptosis, autophagy, and inflammation through repressing the p53 pathway. It further illustrates the protective mechanisms of luteolin on METH-induced hepatotoxicity and provides a research basis for clinical treatment.
Time-Dependent Fractional Diffusion and Friction Functions for Anomalous Diffusion
Authors: Bao Jing-Dong
Published: February 2021

The precise determination of diffusive properties is presented for a system described by the generalized Langevin equation. The time-dependent fractional diffusion function and the Green-Kubo relation as well as the generalized Stokes-Einstein formula, in the spirit of ensemble averages, are reconfigured. The effective friction function is introduced as a measure of the influence of frequency-dependent friction on the evolution of the system. This is applied to the generalized Debye model, from which self-oscillation emerges as indicative of ergodicity that breaks due to high finite-frequency cutoff. Moreover, several inconsistent conclusions that have appeared in the literature are revised.
The Barley (Hordeum vulgare ssp. vulgare) Respiratory Burst Oxidase Homolog (HvRBOH) Gene Family and Their Plausible Role on Malting Quality
Authors: Mahalingam Ramamurthy , Graham Danielle , Walling Jason G.
Published: February 2021

Controlled generation of reactive oxygen species (ROS) is pivotal for normal plant development and adaptation to changes in the external milieu. One of the major enzymatic sources of ROS in plants are the plasma-membrane localized NADPH oxidases, also called as Respiratory Burst Oxidase Homologs (RBOH). In addition to the six previously reported, seven new members of RBOH gene family were identified in barley usingin silicoanalysis. Conservation of genomic structure and key residues important for catalytic activity and co-factor binding was observed in barley RBOH genes. Phylogenetic analysis of plant RBOHs revealed distinct clades for monocot and dicot RBOH proteins. Hence, we propose to use the rice nomenclature for naming barley RBOH genes. Temporal changes in ROS profiles were observed during barley malting and was accompanied by changes in protein carbonylation, lipid peroxidation, and antioxidant capacity. Among the nine differentially expressed HvRBOHs during various malting stages, HvRBOHA and HvRBOHC showed most significant sustained changes in expression. RNAi knockdown lines with reduced expression of HvRBOHA/C gene exhibited genetic compensation via inducible expression of other gene family members during malting. However, the physiological consequence of reduced expression of HvRBOHA/C manifested as a poor malting quality profile attributable to low alpha-amylase activity and high levels of beta-glucan. We propose that the HvRBOHs play a critical role in modulating the redox milieu during the early stages of malting, which in turn can significantly impact carbohydrate metabolism.

Published: February 2021

Forage quality determined mainly by protein content and fiber composition has a crucial influence on digestibility and nutrition intake for animal feeding. To explore the genetic basis of quality traits, we conducted QTL mapping based on the phenotypic data of crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and lignin of an F1 alfalfa population generated by crossing of two alfalfa parents with significant difference in quality. In total, 83 QTLs were identified with contribution to the phenotypic variation (PVE) ranging from 1.45 to 14.35%. Among them, 47 QTLs interacted significantly with environment and 12 QTLs were associated with more than one trait. Epistatic effect was also detected for 73 pairs of QTLs with PVE of 1.08–14.06%. The results suggested that the inheritance of quality-related traits was jointly affected by additive, epistasis and environment. In addition, 83.33% of the co-localized QTLs were shared by ADF and NDF with the same genetic direction, while the additive effect of crude protein-associated QTLs was opposite to that fiber composition on the same locus, suggesting that the loci may antagonistically contribute to protein content and fiber composition. Further analysis of a QTL related to all the three traits of fiber composition (qNDF1C, qADF1C-2, and qlignin1C-2) showed that five candidate genes were homologs of cellulose synthase-like protein A1 in Medicago truncatula, indicating the potential role in fiber synthesis. For the protein-associated loci we identified, qCP4C-1 was located in the shortest region (chr 4.3 39.3–39.4 Mb), and two of the seven corresponding genes in this region were predicted to be E3 ubiquitin-protein ligase in protein metabolism. Therefore, our results provide some reliable regions significantly associated with alfalfa quality, and identification of the key genes would facilitate marker-assisted selection for favorable alleles in breeding program of alfalfa quality improvement.

Published: February 2021

Yam (Dioscorea spp.) is a major food security crop for millions of resource-poor farmers, particularly in West Africa. Soil mineral deficiency is the main challenge in yam production, especially with the dwindling of fallow lands for the indigenous nutrient supply. Cultivars tolerant to available low soil nutrients and responsive to added nutrient supply are viable components of an integrated soil fertility management strategy for sustainable and productive yam farming systems in West Africa. This study’s objective was to identify white Guinea yam (D. rotundata) genotypes adapted to available low soil nutrients and responsive to externally added nutrient supply. Twenty advanced breeding lines and a local variety (Amula) were evaluated under contrasting soil fertility, low to expose the crop to available low soil nutrient supply and high to assess the crop response to added mineral fertilizer (NPK) input at Ibadan, Nigeria. The genotypes expressed differential yield response to low soil fertility (LF) stress and added fertilizer input. Soil fertility susceptibility index (SFSI) ranged from 0.64 to 1.34 for tuber yield and 0.60 to 1.30 for shoot dry weight. The genotypes R034, R041, R050, R052, R060, R100, and R125 combined lower SFSI with a low rate of reduction in tuber yield were identified as tolerant to LF stress related to the soil mineral deficiency. Likewise, the genotypes R109, R119, and R131 showed high susceptibility to soil fertility level and/or fertilizer response. Genotypes R025 and R034 had the tuber yielding potential twice of that the local variety under low soil nutrient conditions. Shoot dry weight and tuber yield showed a positive correlation both under low and high soil fertility conditions (r = 0.69 and 0.75, respectively), indicating the vigor biomass may be a morphological marker for selecting genotypes of white Guinea yam for higher tuber yield. Our results highlight genotypic variation in the tolerance to low soil nutrients and mineral fertilizer response in white Guinea yam to exploit through breeding and genetic studies to develop improved genotypes for low and high input production systems in West Africa.

Published: February 2021

This study compares cognitive and emotional responses to 360-degree vs. static (2D) videos in terms of visual attention, brand recognition, engagement of the prefrontal cortex, and emotions. Hypotheses are proposed based on the interactivity literature, cognitive overload, advertising response model and motivation, opportunity, and ability theoretical frameworks, and tested using neurophysiological tools: electroencephalography, eye-tracking, electrodermal activity, and facial coding. The results revealed that gaze view depends on ad content, visual attention paid being lower in 360-degree FMCG ads than in 2D ads. Brand logo recognition is lower in 360-degree ads than in 2D video ads. Overall, 360-degree ads for durable products increase positive emotions, which carries the risk of non-exposure to some of the ad content. In testing four ads for durable goods and fast-moving consumer goods (FMCG) this research explains the mechanism through which 360-degree video ads outperform standard versions.
The Mediating Role of Stress Perception in Pathways Linking Achievement Goal Orientation and Depression in Chinese Medical Students
Authors: Wang Yan , Liu Luping , Ding Ning , Li Honghe , Wen Deliang
Published: February 2021

Mental health problems are frequent obstacles in medical students’ careers as doctors. Given that previous studies overlook the mediation of stress perception, the current study expanded previous goal orientation researches by addressing an unexplored mechanism. This study aims to examine the mediational roles of stress perception (perceived stressors and stress-related cognition) on the relationship between achievement goal orientation and depression in medical students. A total of 1,015 Chinese 2-year medical students completed a multi-section questionnaire. Hypotheses were examined by structural equation modeling. The findings suggest that performance-avoidance goal orientation and perceived stressors both demonstrated direct facilitative effects on depression, whereas stress-related cognition demonstrated direct obstructive effects on depression. Both perceived stressors and stress-related cognition mediated the relationship between achievement goal orientation and depression. The findings spark a new perspective on motivational intervention that assist students in adopting mastery-approaching strategy as well as ways of coping with stressful academic situations. Identifying students with achievement goal orientation and providing them with the appropriate supportive services may help them to manage stress and mitigate or prevent depression.

Authors: Liu Weijun , Tian Yu , Yan Xinyu , Yang Jiemin
Published: February 2021

Objective: The purpose of this study is to evaluate whether the impulse inhibition ability with methamphetamine dependents would vary at different abstinence stages.

Methods: Sixty-three methamphetamine dependents, including 31 short-term (< 10 months) and 32 long-term (≥ 10 months) abstinence participants, were recruited for this study. In addition, 33 men were recruited as the healthy control (HC) group. All participants performed a two-choice oddball task, which is well-established to assess impulse inhibition. Accuracy for deviant trials and deviant–standard reaction time (RT) delay were computed as indexes of impulse inhibition.

Results: The accuracy for deviant trials was significantly decreased in short-term abstinence subjects (90.61%) compared to HC subjects (95.42%, p < 0.01), which was coupled with a shorter RT delay reflecting greater impulsivity in the short-term group vs. the HC group (47 vs. 73 ms, p < 0.01). However, impulse inhibition was improved in the long-term group, shown by the increased accuracy for deviant trials in the long-term group compared to the short-term group (94.28 vs. 90.61%, p < 0.05) and the similar accuracy for the long-term and HC groups (p > 0.05). Further regression analyses confirmed that the abstinence duration positively predicted impulse inhibition of methamphetamine dependents, both in accuracy and RT for deviant stimulus (β = 0.294, p = 0.019; β = 0.337, p = 0.007).

Conclusion: These results suggest that long-term abstinence is more effective in improving impulse inhibition with methamphetamine dependents.
Lessons From Joint Improvisation Workshops for Musicians and Robotics Engineers
Authors: Carter Anthonia , Papalexandri-Alexandri Marianthi , Hoffman Guy
Published: February 2021

We report on a series of workshops with musicians and robotics engineers aimed to study how human and machine improvisation can be explored through interdisciplinary design research. In the first workshop, we posed two leading questions to participants. First, what can AI and robotics learn by how improvisers think about time, space, actions, and decisions? Second, how can improvisation and musical instruments be enhanced by AI and robotics? The workshop included sessions led by the musicians, which provided an overview of the theory and practice of musical improvisation. In other sessions, AI and robotics researchers introduced AI principles to the musicians. Two smaller follow-up workshops comprised of only engineering and information science students provided an opportunity to elaborate on the principles covered in the first workshop. The workshops revealed parallels and discrepancies in the conceptualization of improvisation between musicians and engineers. These thematic differences could inform considerations for future designers of improvising robots.
Sclerosing Angiomatoid Nodular Transformation of the Spleen: Analysis of Clinical and Pathological Features in Five Cases
Authors: Shao Huijiang , Lu Baochun , Shen Zhihong , Liu Fang
Published: February 2021

Objective: We aimed to summarize the clinical and pathological features of sclerosing angiomatoid nodular transformation (SANT) in spleen among five cases.

Methods: Five cases (male: 3; female: 2; mean age: 47.6 years) with SANT confirmed by pathological analysis between July 2010 and November 2019 in our hospital were included in this study. The clinical, imaging, and pathological data were analyzed retrospectively.

Results: Three patients presented with mild abdominal pain or discomfort, while the other two were symptom free. Two patients received ultrasonography (US), and all patients underwent a computerized tomography (CT) scan in our hospital. The typical “spoke wheel” pattern was seen in two cases, and central calcification was detected in one case on the CT scans. All patients indicated peripheral enhancement around the SANT lesion during the arterial phase. Open or laparoscopic splenectomy was performed for treatment. No patient showed recurrence in the follow-up. The pathological characteristics of our cases were in line with those of previous literatures.

Conclusions: Peripheral enhancement around the SANT lesion during the arterial phase should be taken into consideration for the diagnosis of SANT as an imaging sign on CT scans. Special attention should be paid to the splenic integrality during the laparoscopic approach, due to the probability of malignancy and the fragility of the spleen.

Published: February 2021

Purpose: The study aimed to investigate the risk factors for postoperative ileus (POI) after small intestinal fistula excision (SIFE) in patients with diffuse extensive abdominal adhesions.

Methods: From October 2010 to December 2019, we enrolled patients who underwent SIFE and had diffuse extensive abdominal adhesions. Patients were divided into the POI group and the non-POI group according to its occurrence. We then investigated and analyzed the clinical characteristics of both groups.

Result: A total of 247 patients were enrolled into the study. There were 100 patients in the POI group, and 147 patients in the non-POI group. A multi-variable logistic regression analysis revealed that blood loss during SIFE (OR = 1.001; 95% CI: 1.000–1.259; P = 0.012), postoperative lactate(OR = 1.212; 95% CI: 1.001–1.304; P = 0.015), grade V abdominal adhesions (OR = 2.518; 95% CI: 1.814–3.44; P = 0.024), and time for recovery of lactate <2 mmol/L (OR = 2.079; 95% CI: 1.599–3.616; P = 0.026) were associated with POI. Moreover, POI was also associated with prolonged postoperative stay in the hospital (HR = 3.291; 95% CI: 2.511–4.172; P = 0.014).

Conclusion: Blood loss during operation, grade V abdominal adhesions, positive fluid balance within 48 h of operation, and time for recovery of lactate were the risk factors for POI after SIFE in patients with diffuse extensive abdominal adhesions.

Published: February 2021

Background: Multivisceral transplantation entails the en-bloc transplantation of stomach, duodenum, pancreas, liver and bowel following resection of the native organs. Diffuse portomesenteric thrombosis, defined as the complete occlusion of the portal system, can lead to life-threatening gastrointestinal bleeding, malnutrition and can be associated with liver and intestinal failure. Multivisceral transplantation is the only procedure that offers a definitive solution by completely replacing the portal system. However, this procedure is technically challenging in this setting. The aim of this study is to describe our experience, highlight the challenges and propose technical solutions.

Materials and Methods: We performed a retrospective analysis of our cohort undergoing multivisceral transplantation for diffuse portomesenteric thrombosis at our institution from 2000 to 2020. Donor and recipient demographics and surgical strategies were reviewed in detail and posttransplant complications and survival were analyzed.

Results: Five patients underwent MVTx. Median age was 47 years (23–62). All had diffuse portomesenteric thrombosis with life-threatening variceal bleeding. Major blood loss during exenteration was avoided by combining two techniques: embolization of the native organs followed by a novel, staged extraction. This prevented major perioperative blood loss [median intra-operative transfusion of 3 packed red blood cell units (0–5)]. Median CIT was 330 min (316–416). There was no perioperative death. One patient died due to invasive aspergillosis. Four others are alive and well with a median follow-up of 4.1 years (0.3–5.9).

Conclusions: Multivisceral transplantation should be considered in patients with diffuse portomesenteric thrombosis that cannot be treated by any other means. We propose a standardized surgical approach to limit the operative risk and improve the outcome.

Published: February 2021

Milk from grazing ruminants is usually rich in beneficial components for human health, but distinguishing milks sourced from grazing is difficult, and this hinders the valuing of the grazing benefit. This study aimed at evaluating the ability of milk biomarkers (1) to trace milks sourced from sheep submitted to different access times (ATs) to pasture and (2) to estimate sheep herbage dry matter intake (HDMI, g DM ewe−1 d−1) and herbage percentage (HP, % DM) in sheep diet. Animal data derive from a published experiment in which six replicated groups of mid-lactation Sarda sheep had ATs of 2, 4, or 6 h d−1 to a ryegrass pasture. Sheep HDMI and HP of each group were measured on four dates in April 2013. Group milk was sampled, and milk fatty acids (FAs) and n-alkanes were determined by gas chromatography. The latter markers were also measured in feces samples bulked by group. The data (N = 24 records) were submitted to Linear Discriminant Analysis (LDA) aimed at distinguishing the AT to pasture based on biomarkers previously selected by Genetic Algorithms (GA). Partial Least Square Regression (PLSR) models were used to estimate HDMI and HP using biomarkers selected by GA. Based on one milk alkane and six milk FAs as biomarkers, estimates of the AT using GA-LDA were 95.8% accurate. The estimation of HDMI by GA-PLSR based on five milk FAs was moderately precise [explained variance = 75.2%; percentage of the residual mean square error of cross-validation over the mean value (RMSECV%) = 15.0%]. The estimation of HP by GA-PLSR based on 1 milk alkane and 10 FAs was precise (explained variance = 80.8%; RMSECV% = 7.4%). To conclude, these preliminary results suggest that milks sourced from sheep flocks with AT to pasture differentiated by 2 h in the range 2–6 h d−1 can be precisely discriminated using milk biomarkers. The contribution of herbage to sheep diet can also be precisely estimated.

Este estudo objetivou compreender o perfil e a percepção ambiental dos professores, atendentes e gestores escolares das unidades de ensino básico, níveis Educação Infantil e Fundamental, de Luiz Alves/SC, nos anos de 2008 e 2018. Para a coleta dos dados, foi utilizado um questionário semiestruturado com perguntas objetivas, com justificativa de respostas em algumas das perguntas. Participaram da pesquisa 56 professores, atendentes e gestores em 2008 e 43 em 2018. Em sua maioria, os professores, atendentes e gestores têm conhecimento do conceito de educação ambiental. A maior parte relatou que aborda o tema em sala de aula, apesar de terem mencionado que materiais didáticos específicos e mesmo palestras poderiam ajudá-los a abordar melhor o tema em suas aulas. Embora tenha sido detectada pouca inclusão de atividades ambientais fora dos espaços escolares, observou-se um aumento nas construções de hortas escolares, grande aliada na abordagem de temas ambientais nas escolas. Percebeu-se uma lacuna entre a teoria e a prática no que tange às mitigações dos problemas ambientais apontados para o município de Luiz Alves. Formações complementares em educação ambiental de maneira integrada, contínua e a longo prazo tornam-se necessárias nas unidades de ensino do município.

Dancing Body as a Social Replica
Authors: Djeparoska Sonja Zdravkova
Published: February 2021

The dance as well as the art is a part of the life of each individual, but they are also a part of the general processes in society. Dance very frequently absorbs, and nevertheless at the same time reflects the conditions that are distinctive of a specific time and space. The dance body is a medium through which the reactions and responses to a specific problem or condition are articulated. In some examples, the body is used as an instrument to promote values often dictated by the centers of power and authority. However, the dancing body is also a channel through which one can follow reactions and answers to a real problems and hardship. This characteristic will be the subject of this analysis. The Middle Ages was chosen to show the manner and forms of reaction created in crisis situations. Although we have very few authentic sources for this period, it was an additional challenge to go deeper, to explore and to emphasize another function of the dance that is not aesthetic, yet socially engaged. The body is a strong articulator and although it is rarely included in general social research, it provides very interesting material and opportunities to decoded states, attitudes and positions on a collective level. The analysis deals with presenting events that feature the medieval period that have been followed and resulted in specific reactions shaped through several dance forms.

Following the pivot to online teaching as a result of COVID-19, discussion has turned to how the “new normal” in higher education will look, in light of rapid changes and technological upskilling that have taken place across the sector. Amongst this discussion, a longstanding debate as to whether higher education should abandon traditional face-to-face lectures has reignited, either because of uncertainty surrounding when large crowds can feasibly and reliably gather, or for pedagogical reasons, such as retaining the use of flipped classrooms or shorter chunks of pre-recorded material that have been developed during the pivot. In this paper, we set out our reflection on this issue based on the evidence available. We conclude that traditional on-campus lectures, and the recordings of those lectures have a place in higher education and the suggestion that they should be abandoned is as unhelpful as the suggestion that they should be the default mode of teaching. When lectures are deliberately chosen as the most appropriate method of teaching and when the same pedagogical care and attention is given as to other modes of delivery, they provide an effective, pragmatic solution, particularly for large classes. Our response to the pivot should not be to abandon lectures but to critically reflect on their purpose and potential.
IELP and Year 10 EAL/D Curriculum in Australia: An investigation into the adequacy of prior knowledge to international students
Authors: Crossley Louise
Published: February 2021

Emerging English as an additional language and dialect (EAL/D) teaching concepts suggest that the current education system for international students is lacking consistency. While the new Victorian Curriculum F-10 EAL 2020 Reporting Tool (DET, 2019), and other initiatives, show efforts being made to support students whose first language is not English, international students continue to struggle to successfully transition from language school to mainstream school education. Data is collected from IELTS Writing band 5 and EAL Developmental Continuum indicator S3 (DET, 2019). It is analysed using mostly Fairclough’s (2013) but also Gee’s (1999) and Foucault’s (cited in Garrity, 2010) definition of Critical Discourse Analysis and supported by Krashen’s Second Language Acquisition Theory (1982) for a look at the psychological impact of the transition on students. An unachievable gap between the existing IELP and EAL/D courses is showcased and found to be caused by unassociated course content, independent governing bodies and inequivalent and inefficient teacher qualifications, restricting Year 10 international students from being successful in their education. A pathway course to provide a common space (Nakata, 2011) between the curriculum expectations of the relevant governing bodies, ESOS (2018) and VCAA (2017) /ACARA (2018b), and broader qualified educators to teach the courses, are recommended.
CREATING STRATEGIC GOALS AND EFFECTIVENESS INDICATORS FOR THE GOVERNMENT REGULATION OF AGRI-FOOD SYSTEMS DEVELOPMENT IN THE REGIONS OF RUSSIA
Authors:   Institute of Agrarian Problems of RAS, Potapov A.P.
Published: February 2021

The aim of the work is to substantiate the possibilities of agreeing on strategic goals and performance indicators of the state regulation in developing the country’s agri-food system and local goals for developing agri-food sectors of the regions. The formation of strategic goals and indicators is due to the significant socio-economic differentiation among the regions according to the main characteristics of agricultural production: the provision of resources, the efficiency of their use, territorial location to the centers of product sales, natural, climatic and soil conditions. The diagram of the relationship between goals, objectives andindicators of state policy in the field of regulation of the development of agri-food systems in regions is presented. The forms of interaction between the management systems of the federal and regional levels on the issues of conducting a coordinated socio-economic policy in the agri-food sphere have been identified. These include: the signing of financial agreements between the Russian Ministry of Agriculture and regional authorities regarding the provision of subsidies for specific areas of agricultural policy; decomposition of target indicators for all regions within a separate indicator or direction; allocation of regions with a special status; co-financing of agricultural policy directions between federal and regional budgets; complementing the goals of the federal level through the implementation of similar directions in the structure of regional policy; general consideration of the regional specifics of Russia. The main directions for creating strategic goals and development indicators of increasing the effectiveness of state regulation of agri-food systems in the regions are proposed: equal distribution of state support funds by reducing the excessive concentration of subsidies in the main agricultural regions; updating the established priority directions for the development of the agro-industrial complex in the regions of Russia; taking into account regional production, social and infrastructural opportunities in the formation of directions of state agrarian policy; differentiation of development goals for AFS in the regions.
TERRITORY BRANDING AS A TOOL FOR MANAGING LOCAL INDUSTRY DEVELOPMENT
Authors:   Moscow International Academy, Rodina E.A.
Published: February 2021

The article considers the concept, the essence and evolution of the concept “territory brand”, and compares commercial and territorial branding; it studies the role of branding in a micro-context (region, city), and also identifies factors that affect the brand of a territory. The author considers various scientific approaches to determining the true goal of territorial branding. Basing on the analysis, the key points of creating a territory brand in the current economic situation are highlighted. The article discusses the features of positioning a territorial brand today. It is noted that currently the branding of the territory is defined with an emphasis on the brand and its ability to differentiate and project an image towards the external audience. The main goal is to go beyond attracting tourists in order to also attract talent, investment capital, infrastructure, etc. The author has developed a model for managing the development of local industry through the creation of a brand of the territory and considered the possibilities and prospects of its application on the example of the Kalyazinsky district, Tver region. The article identifies three main goals for which the branding of the territory should be focused: ensuring identification and commitment from the local population and business structures, acting as a mechanism that can generate positive audience perceptions about a given territory, as well as serving the interests of the development of territorial entrepreneurship. At the end, the author made the main conclusion that territory brand is a necessary and extremely important asset in poaching investment capital, talent, infrastructure, enterprises and events, among other advantages.
MEMBERSHIP OF SHARED HOUSING CONSTRUCTION
Authors:   Magnitogorsk State Technical University, Kiva-Khamzina Y.L.
Published: February 2021

The purpose of this work is to study the problems of legal regulation of relations in the field of shared construction in Russia at the present stage. In particular, the subject structure of the legal relationship in shared housing construction is being investigated. In recent decades, the practice of shared housing construction with attracting funds from individuals has shown the advantages of this form of investment activity in Russia and abroad. Using the practice of shared housing construction made it possible to solve the problem of providing housing and improving the living conditions of the population in different countries of the world as a way of efficiently investing funds and the ability to pay for the acquired property in installments at a price lower than its nominal value. These factors determine the attractiveness of entrepreneurial activity in housing construction for developers, but at the same time, abuses are inevitable, which lead to a situation of “defrauded equity holders”. Methods: dialectical, legal hermeneutics, formallogical analysis, historical-legal, statistical, system-structural, comparative analysis, generalization and others. Research results: the parts of legal relations in shared construction are: the developer, the shared construction members - individuals and legal entities, the bank accredited by the state that controls the use of funds by the developer. Economic security of the legal relations subjects in shared housing construction is ensured by the intermediation of banking structures, which reduces risks and losses for participants in shared construction. And also the most important principle of the developer’s activity today is the openness of information, which is implemented through the developer’s obligation to post information about the financial statements on its official website and in the Unified Housing Information System.
Paul Ricœur et le destin de la phénoménologie
Authors: de Gramont Jérôme
Published: February 2021

Every reader of Ricœur knows that hermeneutics endeavors to answer the aporiae of historical phenomenology. Hence arises the need to return to those aporiae and those answers. On the one hand, phenomenology, born with the maxim of going “directly to things themselves,” is confronted with the incessant evasion of the thing itself and with its dreams of presence being thereby shattered. This reversal should not be blamed on the failings of this or that thinker, but attributed to the very destiny of phenomenology itself. On the other hand, Ricœurian hermeneutics takes note of a gap (the very remoteness of the thing itself), and of a necessary return (to the thing of the text). Thus, there is nothing for thought itself to grieve over with respect to this enterprise. However, while the phenomenology of Merleau-Ponty, faced with the same difficulties, orients itself towards political philosophy, the hermeneutics of Ricœur rather seeks to lead us to a philosophy of religion. This article hypothesizes that, in spite of the formula (inherited from Thévenaz) of a “philosophy without an absolute,” the thought of Ricœur heads in fair measure towards the Absolute, and that ontology is not the only name of the Promised Land.
Tactical urbanism or revitalization – a city tailored for the people
Authors: Gaweł Dariusz
Published: February 2021

We live in the conditions of constantly changing cities. Spatial transformations taking place before our eyes concern both older districts, housing estates as well as technical infrastructure or non-urbanized areas. The participation of social organizations and the inhabitants themselves is very important for the success of the entire change process. So far, revitalization has been the most popular process of renewal in Poland. In recent years in many degrading cities of the world, tactical urban projects have proved to be a particularly popular and effective process of transforming public space. This article is an attempt to compare both processes in selected cities, taking into account the benefits of implementing them.
